[0002] Currently, the coal slag / rock slag discharged from the coal mine underground drilling is usually transported out of the roadway in two ways. The first way is that if there is a transportation belt in the roadway, the accumulated coal slag / rock slag is shovelled onto the belt by an operator, and then transported out of the roadway. The second way is that if there is no transportation belt in the roadway, the accumulated coal slag / rock slag is shovelled into a woven bag by a worker, and then pulled out of the roadway by a mine car.

The device can realize that the cinder does not fall to the ground in cooperation with a cinder water separator.

[0040] Working principle:

[0041] The woven bag opening is hung on the hook 15, so that the woven bag opening can completely wrap the discharge opening. The full-hydraulic control system provides four oil sources, three of which are power oil sources, respectively supplying the compression hydraulic cylinder 42, the sliding door hydraulic cylinder 22 and the pushing-out hydraulic cylinder 32; one of which is a control oil source, supplying the control oil circuit. The compression hydraulic cylinder 42 moves to the direction of the stop plate end point hydraulic travel valve one 8.1 under the action of the compression hydraulic cylinder control valve (two-position four-way hydraulic control double-side pilot reversing valve), and when the compression hydraulic cylinder connecting seat 7.1 touches the stop plate end point hydraulic travel valve one 8.1, the compression hydraulic cylinder control valve is reversed, so that the compression hydraulic cylinder 42 moves to the direction of the stop plate end point hydraulic travel valve two 8.2, until the compression hydraulic cylinder connecting seat 7.1 touches the stop plate end point hydraulic travel valve two 8.2, the compression hydraulic cylinder control valve is reversed again, so as to realize the reciprocating action of the compression hydraulic cylinder. The compression hydraulic cylinder 42 drives the compression member 41 to reciprocate, the cinder enters the inside of the box body 12 through the hopper 11, and is compacted by the reciprocating compression member 41. With the increase and extrusion of the cinder in the box body 12, the cinder triggers the spring 53 in the compression trigger assembly 5, until the stop plate 51 triggers the stop plate end point hydraulic travel valve one 8.3.1 and the stop plate end point hydraulic travel valve two 8.3.2. After the stop plate end point hydraulic travel valve one 8.3.1 is triggered, the power oil supplied to the compression hydraulic cylinder 42 is directly returned to the oil tank, and the compression hydraulic cylinder 42 stops moving. After the stop plate end point hydraulic travel valve two 8.3.2 is triggered, the sliding door hydraulic cylinder control valve (two-position four-way hydraulic control single-side pilot reversing valve) is controlled, so that the control sliding door hydraulic cylinder 22 is retracted. When the stop plate end point hydraulic travel valve two 8.3.2 is not triggered, the sliding door hydraulic cylinder control valve continuously supplies oil to the no-rod cavity of the sliding door hydraulic cylinder, so that the sliding door hydraulic cylinder 22 is in the extended state. When the stop plate end point hydraulic travel valve two 8.3.2 is always in the contact state, the rod cavity of the sliding door hydraulic cylinder is in the continuous oil supply state, and the sliding door hydraulic cylinder 22 is in the continuous retraction state. After the sliding door hydraulic cylinder 22 drives the sliding door 21 to retract, the discharge opening is opened, and after the discharge opening is completely opened, the sliding door hydraulic cylinder starting point hydraulic travel valve 8.4 is triggered. After the sliding door hydraulic cylinder starting point hydraulic travel valve 8.4 is triggered, the pushing-out hydraulic cylinder control valve (two-position four-way hydraulic control single-side pilot reversing valve) is controlled, and the pushing-out hydraulic cylinder 32 is controlled by the pushing-out hydraulic cylinder control valve to push the compacted cinder in the box into the woven bag. When the pushing-out is completed, the pushing-out member contact block 7.2 triggers the pushing-out hydraulic cylinder starting point hydraulic travel valve one 8.5.1 and the pushing-out hydraulic cylinder starting point hydraulic travel valve two 8.5.2. The pushing-out hydraulic cylinder starting point hydraulic travel valve one 8.5.1 blocks the left-side pilot oil supply of the sliding door hydraulic cylinder control valve, and makes the left-side control oil return to the oil tank. The sliding door hydraulic cylinder control valve is reversed under the action of the spring force, the sliding door hydraulic cylinder 22 is extended, and the discharge opening is closed. The pushing-out hydraulic cylinder starting point hydraulic travel valve two 8.5.2 blocks the left-side pilot oil supply of the pushing-out hydraulic cylinder control valve, and the pushing-out hydraulic cylinder control valve is reversed under the action of the spring force, the pushing-out hydraulic cylinder 32 is extended, and the pushing-out member 31 is retracted.After the pusher 31 is fully retracted, the material blocking plate 51 is reset under the action of the spring, the material blocking plate end liquid pressure stroke valve one 8.3.1 and the material blocking plate end liquid pressure stroke valve two 8.3.2 are disconnected, the material blocking plate end liquid pressure stroke valve one 8.3.1 is disconnected to restore the oil supply of the compression hydraulic cylinder 42, the compression hydraulic cylinder 42 continues to reciprocate, and the whole operation enters the next cycle.

[0042] Finally, it should be pointed out that the above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, and they should be covered in the scope of the claims of the present application.
