(54) CRUSHING PLANT

The invention relates to a device for grinding materials and can be used in mining, construction and other industries of Usti.

A known installation for crushing, including a receiving hopper with a safety grill, crusher. Г ^ З The disadvantage of this design is the impossibility of crushing oversize.

The purpose of the invention is the provision of the possibility of crushing oversized on a safety’s grate. _

This goal is achieved by the fact that the crushing plant, including the receiving hopper with the safety grill, the crusher, is equipped with a platform on which the crushing device and pusher are mounted, 20 while the platform is connected to the safety grill from the opposite side to the loading.

Figure 1 schematically shows a 25 installation for crushing; in Fig.2 node I in Fig.1 '(platform with a pusher mounted on it and a crushing device); in Fig.Z - node. I, top view; figure 4 - installation 30 of one of the guides of the pusher in the groove of the frame of the safety grill. The crushing plant consists of a receiving hopper 1 with a safety grill 2, a crusher 3, a conveyor 4. On the opposite side to the loading, a platform 5 is mounted on the safety grill 2, on which the pusher 6 with side walls 7. is mounted. guides 8 installed in the grooves of the frame 9, which is common for both the safety grill 2 and the platform 5. The pusher 6, through shock absorbers, for example, Belleville springs 10, is supported by a rigid wall 11, which is supported from below by the column 12 and the foundation of the entire crushing plant. Half couplings 13 are attached to the rear wall of the slider 6 for connecting the slide with the drive, for example, with the half coupling 14, rods 15, hydraulic cylinder 16. The stand 17 with guides 18 for the crushing device 19, which, for example, is made in the form of butters with drive 20, an electric motor for crushing a piece of rock 21 that has not passed into the cells of the safety grill

814460 4 when feeding the Rock mass onto it from a dump truck 22.

Installation for crushing works as follows.

From the dump trucks 22, the rock mass flows through the safety grate 2 into the receiving hopper 1, the crusher 3 and onto the conveyor 4. When loading the rock mass with an excavator with a large bucket capacity, a piece that is oversized through the receiving hole can enter the receiving grate 2 crushers

3. Such pieces are rolled onto the platform 5, where they are held by the pusher B and the wall 11. The impact of the piece 21 on the pusher 6 is mitigated by shock absorbers, for example, Belleville springs 10. 15

A crushing device 19 is supplied to a piece 21 and crushes it to overall pieces. After that, the drive of the pusher 6 is turned on, the hydraulic cylinders 16 bring the rods 15 with half-couplings 14 to the 20 half-couplings 13 of the slider and engage them. The pusher 6 moves the crushed pieces onto the safety grill 2 and they enter the receiving hopper 1 and the crusher, and the pusher jg body b is returned by the hydraulic actuator to its original position. Oversized pieces can be crushed anywhere in the platform 5, since the crushing device 19 is made movable along the guide rail 18 and equipped with a drive 20. * 0

So that the hydraulic actuator 16 does not take the blow from the piece falling on the pusher 6 and, when it is crushed, the rod 15 is coupled to the pusher with half-couplings 13 and 14 only for shifting the fragmented 35 pieces to the safety grill 2. After the pusher returns to its original position, the half-couplings 13 and 14 are disengaged.

Using the installation for crushing provides the possibility of crushing oversized pieces directly when feeding the rock mass to the safety grill. This eliminates the stoppage of the transshipment point, the explosion of oversized pieces near the transshipment point, or the use of a mobile retrofit installation.

Claims (1)

 The invention relates to devices for grinding materials and can be used in the mining, construction and other industries. A known crushing plant, comprising, a receiving hopper with a safety grate, a crusher .flj. The disadvantage of this design is the impossibility of crushing oversize. The purpose of the invention is to provide the possibility of maintaining oversize on the safety grids. This goal is achieved by the fact that a crushing plant, including a receiving hopper with a safety grid, a crusher, is equipped with a platform on which a crusher device and a pusher are mounted, while the platform is attached to the safety grid on the side opposite to the load. 1 shows a schematic of a crushing plant; in Fig. 2, node I in Fig. 1 (a platform with a pusher mounted on it and a splitter); on fig.Z - left. I, top view; Fig. 4 shows the installation of one of the pusher guides in the slot of the safety grate frame. The crushing unit from the receiving bin 1 with the safety grid 2, the crusher 3, the conveyor 4 is installed. On the opposite side of the load, an area 5 is mounted on the safety grid 2 On which the pusher 6 is mounted with side walls 7. In the upper part of the pusher 6 there are made guides 8 installed in the grooves of the frame 9, which is common both for the safety grid 2 and for the junction 5. The pusher 6 is through shock absorbers, for example elchatye spring 10, is supported on a rigid wall 11 which is supported by the bottom column 12N foundation entire installation for crushing. To the rear wall of the slider 6, coupling halves 13 are attached to connect the slide with a drive, for example, coupling half 14, rods 15, hydraulic cylinder 16. On platform 5, a fixed rack 17 with guides 18 for a crushing device 19, for example, is made butoboys with a drive 20, an electric motor for crushing a piece of rock 21 that did not pass into the cells of the safety grid 2 when feeding the mountain mass from the dump truck 22. The installation for crushing works as follows. From dump trucks 22, the flow of rock mass flows through the safety grate 2 to the receiving bunker 1, crusher 3 and to the conveyor 4. When loading the mountain mass by an excavator with bsgN Iyu bucket capacity, a piece oversize through the receiving opening of the crusher 3 can enter the receiving grate 2 the pieces roll onto the platform 5, where they are held by the pusher 6 and the wall 11. The impact of the piece 21 on the pusher 6 cm is damped by shock absorbers, for example cup springs 10. The piece 21 is fed by the crushing device 19 and is crushed to size pieces. After that, the drive of the pusher b is turned on, the hydraulic cylinders 16 move the rods 15 with the coupling halves 14 to the coupling halves 13 of the slide, and engage them. The pusher 6 moves the crushed pieces to the safety grid 2 and they enter the receiving bunker 1 and the crusher, and the pusher b is returned to the initial position by a hydraulic actuator. Oversized pieces can be crushed anywhere on site 5, since the crusher device 19 is made movable along guide rails 18 and equipped with a drive 20. So that the hydraulic actuator 16 does not take the blow from the piece falling on the pusher and during its crushing; the rod 15 is coupled with the pusher with the half couplings 13 and 14 just to shift the crushed pieces to the safety grid 2. After the pusher has returned to its original position, the coupling half 13 and 14 are disengaged. The use of a crushing plant provides the possibility of crushing oversized pieces directly when the rock mass is fed to a safety grid. This eliminates stopping the operation of the transshipment point, blasting oversized pieces near the transshipment point or using a mobile crushing unit. The invention of the crushing plant, including a receiving hopper with safety grille, crusher, characterized in that, in order to ensure the possibility of crushing of oversize on the safety grille, the installation is equipped with a platform on which the crushing device and the pusher are mounted, while the platform is attached to safety guard on the opposite side of the load.
