Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

This specific embodiment is only an explanation of the present invention, and it does not limit the present invention. Those skilled in the art can make modifications without creative contribution to the present embodiment as required after reading this specification, but as long as the rights of the present invention are used All claims are protected by patent law.

Example 1, as shown in FIG. 1 , includes a feeding port 2, which is connected to a slag silo, and wastes such as coal slag enter the feeding port 2 from the slag silo. In this embodiment, coal slag is used as an example, but the technical solution is not limited to the collection and transportation of coal slag, and is applicable to the collection of most granular or powdered industrial products. Below the feeding port 2, there is a double-tube channel extending in the vertical direction. The double-tube channel is double-layered. The inner layer is made of rigid material, such as the inner telescopic tube 4 of steel material, and the outer layer is The outer telescopic cylinder 3 is made of elastic material, such as rubber material. A discharge head 5 is connected to the lower end of the double-layer channel, the upper end of the discharge head 5 is connected to the outer telescopic cylinder 3, and the lower end is connected to a dust cover 7. Below the unloading head 5 there is a transport vehicle. The transporter and the slag bin are not shown in Figure 1.

In actual work, the operator first swipes the card on the operating device, and only the card-swiping system records the cardholder information, the time of operating the device and other information. At this time, the entire control system controls the plug board of the slag bin and the discharge opening device 8 to be closed, and the material will not fall, which is convenient for the operator to work safely. After the operator drives the transport vehicle to the designated position, the system can be turned on through the switch. First, enter the descending step of the binocular channel.

As shown in FIG. 1 and FIG. 2 , the traction device includes a power device 12 and a traction rope 11 . The power device 12 includes common driving components and transmission components, such as a motor, a reducer, a transmission wheel, etc., to drive the movement of the traction rope 11 . The outer telescopic cylinder 3 includes a cylindrical rubber outer layer 31. At different height positions of the rubber outer layer 31, for example, a ring-shaped connecting section 32 is arranged every 0.5 meters, and each connecting section 32 is provided with a connecting rope ring 33. , one end of the traction rope 11 is connected to the power device 12 , and the other end is connected to the discharge head 5 . The unloading head 5 is originally located at a high position. Under the action of the traction device 1, the traction rope 11 is lowered, and the originally folded outer telescopic barrel 3 stretches and walks down.

Inside the outer telescopic barrel 3 is an inner telescopic cylinder 4, and the inner telescopic cylinder 4 adopts a multi-cone laminated structure. Specifically, as shown in FIG. 2 , it includes a plurality of single vertebral bodies 41 , which are connected in series with each other using connecting ropes. Each of the single vertebral bodies 41 is a conical structure with a wide upper part and a narrow lower part, and penetrates in the vertical direction. It includes an upper main portion 411 and a lower folded portion 412 at a lower position with a slightly smaller opening. When the discharge port 5 is at a high position, the plurality of single vertebral bodies 41 are overlapped and sleeved with each other. When the discharge head 5 descends, the plurality of single vertebral bodies 41 are opened to each other, the distance is increased, and the synchronous downward extension.

The expansion and contraction modes of the inner and outer cylinders are different. The lower end of the outer expansion and contraction cylinder 3 is directly connected to the discharge head 5 , and its rise and fall are directly driven by the traction rope 11 . The inner telescopic cylinder 4 has no power components directly connected to it, and the single vertebral body 41 at the lowermost end collides with the discharge head 5. During the lifting and lowering of the discharge head 5, the inner telescopic cylinder 4 also expands and contracts.

When the double-tube channel is extended to a predetermined length, that is, the unloading head 5 has reached the bottom position of the hopper of the transport vehicle, then the next step, namely, the unloading step, begins. At this time, first open the plug board of the upper slag bin, and the plug board is opened by its plug board valve. The material begins to fall and falls in the inner telescopic cylinder 4 . The inner telescopic cylinder 4 is made of steel, which has high strength and long service life. Since a plurality of single vertebral bodies 41 are folded and arranged, they are constantly in contact with the deceleration slope 413 during the descending process of the material, and the deceleration slope 413 is inclined and arranged to slow down the descending speed of the material.

In this technical solution, the plug board of the slag silo and the discharge opening device 8 adopt a time delay design. That is, after the plug board is opened for a preset time, the discharge opening device 8 is opened. This uses its own structure to maximize the reduction of the speed of material falling, which not only reduces the impact on the truck, but also reduces the spread of dust.

The specific structure of the discharge opening device 8 can be shown in FIG. 3 , including two rotating half bins 81 that can rotate in the vertical direction, which are located opposite to each other, and are connected by a pushing device 83 such as an oil cylinder. When it needs to be opened, the oil cylinder works and the piston cylinder is pushed out. A rotating gear 82 is arranged on each rotating half-silo 81 , and the two rotating gears 82 are meshed with each other to ensure the stability of rotation and the rotation stroke.

A spray device 6 and a dust cover 7 are provided on the discharge port 5 . When the discharge opening device 8 is opened, the spraying operation is performed synchronously. The spray device 6 includes an annular annular pipeline 61, and a plurality of spray ports 62 are arranged at annular intervals on the annular pipeline 61 to further reduce the flying of dust.

Then, it goes to the next step, that is, the step of shrinking the double-tube channel and raising the discharge port 5 . When the material is falling, the traction rope 11 pulls the unloading head 5 to rise slowly, which also makes the material gradually pile up in an orderly manner after entering the top of the hopper of the transport vehicle, which has the effect of shaping the material.

When the unloading head 5 reaches the highest position, first close the plug board of the slag bin, and then close the discharge opening device 8, the unloading is completed, and the transport vehicle drives away. When the next transport vehicle arrives, repeat the above steps to realize intelligent dust-free unloading and loading.
