Description

Technical Field

The present invention relates to a crushing plant for working inert material with interchangeable and perfected crushing unit. Specifically, the crushing plant is multipurpose and adapted to crush the inert material by means of a perfected crushing unit, as well as adapted to sieve and eject such material. For example, the crushing plant is of the type distributed by the company RIMAC TECHNOLOGY SA under the name MOBY 535 TRANSFORMER, MOBY 645 TRANSFORMER, MOBY 850 TRANSFORMER, MOBY 960 TRANSFORMER, MOBY 1160 TRANSFORMER, MOBY 1265 TRANSFORMER, MOBY 1180 TRANSFORMER, MOBY 1380 TRANSFORMER.

Background Art

Crushing plants are known in the state of the art. Particularly, inert material crushing plants are mainly divisible into two categories of plants: mobile plants and stationary plants.
The known mobile crushing plants comprise a frame and transport means connected to the frame and defining a bearing portion of the plant to the ground. The transport means are known per se and may comprise a set of tracks or tires to move the plant. The mobile crushing plants are then able to move independently, e.g. from a transport device to the work site.
On the other hand, the known stationary crushing plants do not comprise transport means and the bearing portion to the ground is stationary and does not allow the movement thereof. Stationary crushing plants can only be moved and positioned at the work site by means of an external transport device and not independently. Known plants comprise at least one material loading unit, generally a hopper, and one crushing unit coupled together and attached to the plant frame. In detail, the hopper is placed upstream of the crushing unit along one direction of development of the plant. Examples of crushing units may be a jaw crusher, a bump crusher and a cone crusher.
More specifically, the hopper is configured to receive the material to be worked and crushed and to convey the material to be worked to the crushing unit located downstream of the loading unit.
The crushing unit is configured to receive the material to be worked from the hopper, crush the material to be worked resulting in a worked material and convey the worked material to a conveyor belt connected to the frame. Normally, the crushing unit is placed between the hopper and the conveyor belt along the direction of development of the plant.
Specifically, the conveyor belt is developed between an input portion, adapted to receive the worked material from the crushing unit, and an evacuation portion. The conveyor belt is configured to move the worked material from the input portion to the evacuation portion. The conveyor belt is also switchable between a working configuration, so that it protrudes sideways from the crushing unit, and a transport configuration, wherein the belt is folded back on itself so as to reduce the overall dimensions of the plant during the movement thereof.
In addition, the crushing plant may comprise a magnetic separator associated with the conveyor belt and configured to detect and remove the metallic elements from the flow of worked material carried by the conveyor belt during use.
One drawback of known crushing plants is that in the event of a malfunction of the crushing unit, it is necessary to stop the operation of the entire crushing plant for long periods to provide maintenance for such a crushing unit. In fact, the Applicant has ascertained that maintenance of the crushing unit in the plant of known type is costly and time-consuming because maintenance must be done directly by operating at the plant and it is not possible to separate such crushing unit from the plant.

Description of the Invention

The Applicant has ascertained that connecting the crushing unit to the plant frame in a removable manner makes it easier to maintain or replace such crushing unit. In addition, the ability to replace the crushing unit allows the versatility of the crushing plant to be increased, e.g. by replacing a crushing unit with a different type of crushing unit.
A further object of this description is to provide a more versatile crushing plant and capable of operating different types of crushing units.
An additional object of this description is to provide a crushing plant that enables faster maintenance of the plant components.
A further object of the present invention is to provide a more efficient crushing plant with reduced downtime.
The aforementioned objects are achieved by the crushing plant with interchangeable crushing unit according to claim 1.

In detail, the loading unit 4 is configured to receive the material to be worked from a feeding unit. The feeding unit may comprise a machine for surface excavation works, transporting and unloading inert material such as, e.g., a bulldozer, a mechanical shovel or an excavator.
The screening unit of the loading unit 4 can be adapted to a phase of a first sieving of the material to be worked, thus separating a first fraction from the material to be worked.

Crushing unit

In one embodiment, the crushing plant 1 comprises a crushing unit 6 connected to the frame 2. The crushing unit 6 is configured to receive at input the material to be worked/processed or sieved material and to send at output the worked/processed material. In detail, the crushing unit 6 is configured to carry out a phase of receiving the material to be worked or sieved, preferably from the loading unit 4, and a phase of conveying and feeding the worked material to one or more conveyor belts. The crushing unit 6 is configured to carry out a process of work on the material to be worked to obtain a worked material. The working phase comprises one or more of the sub-phases:

reducing an average granular size of the material received at input,
carrying out a second sieving of the material received at input.

Conveyor belt

The crushing plant 1 comprises a conveyor belt 7 connected to the frame 2. The conveyor belt 7 mainly extends along a longitudinal direction A-A between an input portion 7a and an opposite evacuation portion 7b. The input portion 7a is adapted to receive material, especially material worked by the crushing unit 6. The evacuation portion 7b is adapted to evacuate the material from the crushing plant 1 and to convey the inert material at output. The conveyor belt 7 is configured to move the inert material from the input portion 7a to the evacuation portion 7b.
According to one aspect, the conveyor belt 7 is switchable between a working configuration and a transport configuration. In particular, the conveyor belt 7 comprises sections 14, 15 connected to each other in a rotatable manner, e.g., by means of pivoting elements. For example, the sections 14, 15 are connected by means of pins defining an axis of rotation around which at least one of the sections is rotatable. In more detail, in the working configuration, the sections 14, 15 are arranged substantially aligned along a straight longitudinal direction, as e.g. shown in Figure 2. In the transport configuration, the sections 14, 15 are close to each other, thus reducing a lateral extension of the conveyor belt 7 with respect to the frame 2, such as e.g. shown in Figure 1. In other words, the overall dimensions of the conveyor belt 7 laterally to the frame 2 is reduced in the switch from the working configuration to the transport configuration to facilitate the movement of the crushing plant 1.

removing the unwanted material from the worked material.

According to a further aspect, the control unit is configured to command the driving unit 10 to carry out a phase of operating the transport means 3 and moving the crushing plant 1.

Crushing plant with interchangeable crushing unit

According to one aspect, the loading unit 4 is connected to the frame 2 and adapted to receive inert material and to feed the inert material to the crushing unit 6. The crushing unit 6 is associated with the loading unit 4 to receive the inert material and configured to perform a working phase of the inert material and to feed the worked inert material to the conveyor belt 7. The conveyor belt 7 connected to the frame 2 is configured to receive and transport the worked inert material. In detail, the loading unit 4 and the crushing unit 6 are arranged along the direction of development B-B of the plant 1 so that the loading unit 4 is upstream of the crushing unit 6. More specifically, the conveyor belt 7 is placed along the direction of development B-B downstream of the crushing unit 6.
The crushing plant 1 comprises release/connecting means 11 to disconnect and/or connect the crushing unit 6 to the frame 2 in a removable manner. The release/connecting means 11 may comprise screw-nut screw and/or screw-bolt pairs. The release/connecting means 11 may be adapted to connect and disconnect the crushing unit 6 to/from the frame 2. The release/connecting means 11 can be activated and deactivated to connect the crushing unit to the frame. In particular, the release/connecting means 11 are configured to connect the crushing unit 6 to the frame 2, when activated. The release/connecting means 11 may attach the crushing unit 6 to the frame 2, when activated.
In one embodiment, the plant 1 is switchable between a blocked configuration and a free configuration. In the blocked configuration, the crushing unit 6 is attached to the frame 2. In the free configuration, the crushing unit 6 is movable away from and/or close to the frame 2. In other words, in the free configuration of the crushing plant 1, the crushing unit 6 is either disconnectable from the frame 2 or disconnected from the frame 2 and movable away from such a frame 2. In the blocked configuration of the crushing plant 1, the crushing unit 6 is constrained or attached to the frame 2 and can be blocked at least partly in contact with such a frame 2. In more detail, the release/connecting means 11 are activated, or active, in the blocked configuration and deactivated in the free configuration. For example, Figure 5 shows a crushing plant 1 wherein the plant is in the free configuration and the crushing unit 6 is disconnected and movable close to/away from the frame 2.
According to one aspect, the frame 2 extends substantially along the direction of development B-B. In detail, in the free configuration, the crushing unit 6 is movable away from the frame and/or close to the frame 2 along a direction of movement X-X which is transverse to the direction of development B-B. In the blocked configuration, the crushing unit 6 is constrained to the frame 2 in the direction of movement X-X. Specifically, the direction of movement X-X can be perpendicular to the direction of development B-B. The direction of movement X-X can be vertical and the direction of development B-B can be horizontal. For example, Figures 4 and 5 show a crushing plant in the free configuration with the direction of movement X-X perpendicular to the direction of development B-B. Again, for example, Figure 6 shows the plant 1 in the blocked configuration wherein the crushing unit 6 is connected to the frame 2 and its movement along the direction X-X is blocked.
Advantageously, moving the crushing unit 6 away from and close to the frame 2 allows the crushing unit to be disconnected from the frame 2 so that it can be moved away from the plant and, if necessary, replaced with an additional crushing unit 6. For example, if the crushing unit 6 were damaged or malfunctioning, it would be possible to disconnect the damaged crushing unit from the frame, and thus from the plant, to replace it with an additional functioning crushing unit 6 without the need to interrupt plant operation for long periods. In fact, the release/connecting means are configured to allow the crushing unit 6 to be released and connected quickly. The crushing plant 1 is configured to release/connect the crushing unit 6 from/to the frame 2 within a maximum time frame of 2 hours, preferably 1 hour, even more preferably half an hour. The release/connecting means advantageously allow the crushing unit 6 to be replaced or disconnected quickly, thus reducing plant downtime and promoting maintenance of the plant and of the crushing unit.
According to one aspect, the crushing unit 6 is connectable and disconnectable to a hydraulic system of the crushing plant in a removable manner. The hydraulic system of the crushing plant can be quickly connected to the crushing unit. Advantageously, the hydraulic system of the crushing plant is configured to be coupled to different types of crushing units. In other words, when replacing or removing the crushing unit, it is possible to disconnect such a crushing unit from the hydraulic system of the plant without implementing changes or replacements to the hydraulic system of the plant. In detail, it is possible to replace a crushing unit with an additional crushing unit without replacing the hydraulic system of the plant and coupling and using the additional crushing unit to the same hydraulic system coupled and previously used by the previous crushing unit.
In use, an overhead crane, a crane or other similar heavy-lifting equipment may be used to move the crushing unit 6 close to/away from the frame 2. Specifically, an overhead crane can move the crushing unit away from/close to the frame 2 vertically and/or along the direction of movement X-X.
According to one aspect, the crushing unit 6 comprises a connecting portion 12 for the connection to the frame 2. The connecting portion 12 of the crushing unit 6 is connected to the frame 2 by means of said release/connecting means 11. Specifically, the crushing unit 6 comprises lateral brackets 17. The connecting portion 12 is defined at least partly by such lateral brackets 17. In detail, each lateral bracket 17 comprises holes adapted to couple to the release/connecting means 11 or adapted to receive such release/connecting means. The holes are sized to receive respective screws of the release/connecting means 11.
In the blocked configuration, the release/connecting means 11 block the relevant movement of the crushing unit 6 with respect to the frame 2 at least along the direction of movement X-X. In detail, the release/connecting means 11 constrain the connecting portion 12 in contact with the frame 2. Specifically, the release/connecting means 11 constrain each lateral bracket 17 of the crushing unit 6 in contact with the frame 2. In other words, each lateral bracket 17 of the crushing unit is locked together with the frame 2 when the plant 1 is in the blocked configuration.
In the free configuration of the plant, the release/connecting means 11 allow the relevant movement of the crushing unit 6 with respect to the frame 2 at least along the direction of movement X-X. Specifically, in the free configuration, the connecting portion 12 is free to move with respect to the frame 2, particularly away from and/or close to such a frame 2. In more detail, in the free configuration, the lateral brackets 17 of the crushing unit are movable away from and/or close to the frame 2. In the free configuration, the release/connecting means 11 may not be inserted into the respective holes of each lateral bracket 17 of the crushing unit and/or may be deactivated.
In one embodiment, the crushing plant 1 comprises a movement system 13 associated with the crushing unit 6. The crushing unit 6 is movable away from the loading unit 4 and/or close to the loading unit 4. The movement system 13 is configured to move at least part of the crushing unit 6 away from the loading unit 4 and/or close to the loading unit 4. For example, Figures 8 to 10 show the movement of the crushing unit 6 towards the loading unit 4. In detail, the distance between the crushing unit 6 and the loading unit 4 decreases from Figure 8 to Figure 10.
According to one aspect, the movement system 13 comprises a cylinder configured to move at least part of the crushing unit 6 with respect to the loading unit 4 and/or with respect to the frame 2. The movement system 13 comprises two cylinders associated with the connecting portion 12. Specifically, each cylinder is associated with a respective lateral bracket 17.
In one embodiment, the crushing unit 6 comprises a cavity 14 adapted to receive the inert material. The cavity 14 has an inlet 14a adapted to receive the inert material from a feeding outlet 15 of the loading unit 4.
The crushing unit 6 is movable with respect to the loading unit 4 among a plurality of positions comprising a close position and a spaced position. In the close position, the inlet 14a of the cavity 14 is in the proximal position with respect to the feeding outlet 15 of the loading unit 4. In the spaced position, the inlet 14a of the cavity 14 is in the distal position with respect to the feeding outlet 15 of the loading unit 4. For example, Figure 8 shows a plant with the crushing unit 6 in a spaced position with respect to the loading unit 4. Again, for example, Figure 10 shows a plant with the crushing unit 6 in a close position with respect to the loading unit 4. In detail, the distance between the crushing unit 6 and the loading unit 4 decreases from the spaced position, shown in Figure 8, to the close position, shown in Figure 10. Conversely, the distance between the crushing unit and the loading unit increases with the movement of the crushing unit from the close position to the spaced position.
In detail, each cylinder is configured to move the crushing unit among the plurality of positions. Specifically, each cylinder is adapted to move the crushing unit 6 with respect to the loading unit 4 from the spaced position to the close position and vice versa.
According to one aspect, the crushing unit 6 is movable among the plurality of positions in the blocked configuration and/or in the free configuration of the crushing plant 1. In other words, the crushing unit may move close to/away from the loading unit 4 both when the plant 1 is in the blocked configuration and when the plant is in the free configuration. In detail, the crushing unit 6 is configured to move among the plurality of positions when the plant is in the blocked configuration and the crushing unit is attached to the frame 2. The movement system 13 is configured to move the crushing unit 6 with respect to the loading unit 4 and/or with respect to the frame 2 when the crushing plant is in the blocked configuration.
In one embodiment, the crushing unit 6 comprises a main body 16 connected to the connecting portion 12. In particular, the main body 16 is configured for the relevant rotation with respect to the connecting portion 12 when moving the crushing unit 6 among the plurality of positions. The main body 16 is configured for the relevant rotation with respect to each lateral bracket 17. In other words, the main body 16 can rotate with respect to each lateral bracket 17. The main body 16 at least partly defines the cavity 14 and the inlet 14a.
In one embodiment, the main body 16 is connected to each lateral bracket 17 by means of a respective cylinder of the movement system 13. Specifically, the rod of each cylinder is attached to the main body 16 and the body of each cylinder is attached to a respective lateral bracket 17. Each cylinder is configured to move the main body 16 with respect to the lateral brackets 17. Specifically, when each cylinder is in an extended configuration, or the cylinder rod is extended with respect to the cylinder body, the crushing unit 6 is in the close position with respect to the loading unit 4. When each cylinder is in a close configuration, or the rod is inserted into the cylinder body, the crushing unit 6 is in the spaced position with respect to the loading unit 4. When moving the crushing unit 6 among the plurality of positions, the main body 16 is configured to move with respect to each lateral bracket 17.
The main body 16 is configured to rotate with respect to the lateral brackets when moving the crushing unit 6 among the plurality of positions. For example, Figures 8 to 10 show the crushing plant 1 wherein the crushing unit moves from the spaced position, shown in Figure 8, to the close position, shown in Figure 10. Each cylinder of the movement system 13 is configured to rotate the main body 16 with respect to the lateral brackets 17.
According to one aspect, the main body 16 is configured to rotate with respect to the frame 2 when moving the crushing unit 6 among the plurality of positions in the blocked configuration and/or in the free configuration of the crushing plant 1. Specifically, the movement system 13 is configured to move the main body 16 with respect to the lateral brackets 17 or with respect to the frame 2 when the crushing plant 1 is in the blocked configuration and the crushing unit 6 is attached to the frame 2.
In one embodiment, the loading unit 4 is movable with respect to the frame 2 from/to a front portion 2a of the frame 2. In detail, the plant comprises movement means associated with the frame 2 and with the loading unit 4. The movement means are configured to move the loading unit 4 with respect to the frame 2 at least from/to the front portion 2a so as to vary a height of the plant 1 and/or a distance between the loading unit 4 and the crushing unit 6.
According to one aspect, the loading unit 4 is configured to move with respect to the frame 2 from/to the front portion 2a in the passage of the crushing unit 6 among the plurality of positions. In other words, when the crushing unit 6 is moved between the close position and the spaced position, the loading unit 4 is configured to move with respect to the frame 2 from/to the front portion 2a.
In detail, in the movement of the crushing unit 6 from the spaced position to the close position, the loading unit 4 is configured to move towards the front portion 2a of the frame 2. When moving the crushing unit 6 from the close position to the spaced position, the loading unit 4 is configured to move from the front portion 2a of the frame 2 towards a rear portion 2b of the frame 2.
According to one aspect, the crushing unit 6 may comprise a jaw crusher, a free hammer crusher, an impact crusher or a cone crusher.
For example, the plant shown in Figures 1 to 3 and in Figures 8 to 10 has a crushing unit 6 comprising a jaw crusher. Again, by way of example, Figures 4 through 7 show a crushing plant with a crushing unit 6 comprising an impact crusher.
