At this time, the operator can carry out coal charging.
Referring to fig. 6 and 13, the oil tank 42 is provided with an oil return pipe 421 in communication, and an end of the oil return pipe 421 away from the oil tank 42 is in communication with the second rodless chamber 522. Referring to fig. 11, a second spring 523 is disposed in the second rod chamber 521, the length of the second spring 523 is reversely identical to the expansion and contraction direction of the second telescopic rod 52, and both ends of the second spring 523 are fixedly connected with the movable end of the second telescopic rod 52 and the fixed end of the second telescopic rod 52, respectively.
Referring to fig. 13 and 14, referring to fig. 5 and 6, the coal box 1 is provided with control assemblies 7, and the control assemblies 7 are provided in two groups and are in one-to-one correspondence with the oil tanks 42. The control assembly 7 includes a fourth telescopic rod 71, a third spring 72, a pull rod 73, and a third communication pipe 74. The movable end of the fourth telescopic rod 71 is inserted on the oil return pipe 421, the fixed end of the fourth telescopic rod 71 is fixedly connected with the outer side wall 12 of the oil return pipe 421, the movable end of the fourth telescopic rod 71 divides the fixed end of the fourth telescopic rod 71 into a fourth rod cavity 711 and a fourth rod-free cavity 712, and the fourth rod cavity 711 is located between the fourth rod-free cavity 712 and the oil return pipe 421.
Referring to fig. 14, the third spring 72 is located in the fourth rodless chamber 712, the length of the third spring 72 is opposite to the extension direction of the fourth telescopic rod 71, two ends of the third spring 72 are fixedly connected with the movable end of the fourth telescopic rod 71 and the fixed end of the fourth telescopic rod 71 respectively, and the third spring 72 is always in a compressed state. The pull rod 73 is inserted on the fixed end of the fourth telescopic rod 71, and one end of the pull rod 73 is positioned in the fourth rodless cavity 712 and is fixedly connected with the movable end of the fourth telescopic rod 71. Referring to fig. 12 and 14, the third communication pipe 74 has one end communicating with the fourth rodless chamber 712, and the other end provided with three branch pipes, and each communicating with the third rod-containing chamber 611, and oil is preset in each of the third communication pipe 74 and the fourth rodless chamber 712.
In the initial state, since the third spring 72 is in the compressed state, the third spring 72 pushes the fourth telescopic rod 71 to extend, so that the movable end of the fourth telescopic rod 71 abuts against the side wall 12 of the oil return tube 421 far away from the fourth telescopic rod 71, and the two ends of the oil return tube 421 are in the isolated state.
As the second telescopic link 52 is extended, the second spring 523 is compressed.
When the coal box 1 is unloaded, an operator pulls the pull rod 73, so that the fourth telescopic rod 71 overcomes the elasticity of the third spring 72 to shrink, the movable end of the fourth telescopic rod 71 is far away from the side wall 12, far away from the fourth telescopic rod 71, of the oil return pipe 421, and two ends of the oil return pipe 421 are in a communicating state. At this time, since the second spring 523 is in a compressed state, the second telescopic rod 52 is contracted and restored under the action of the second spring 523, so that the oil in the second rodless chamber 522 flows back into the oil tank 42 through the oil return pipe 421. The second telescopic rod 52 is contracted and drives the second rotating rod 322 to rotate around the rotation axis of the second rotating rod 322, so that the second sliding block 3212 is pushed to slide in the through groove, the second sliding block 3212 drives the sliding rod 321 to slide in the sliding groove, the sliding rod 321 slides to drive the first rotating rod 31 to rotate around the rotation axis of the first rotating rod 31, one end, far away from the sliding rod 321, of the first rotating rod 31 is rotated away from the frame 11, and the bottom plate 13 and the frame 11 are fixed in a cancel mode.
When the bottom plate 13 and the frame 11 are not fixed, under the action of gravity of coal in the coal box 1 and the bottom plate 13, the bottom plate 13 rotates downwards around the hinge axis of the bottom plate 13 and the frame 11 to be opened, and at the moment, the coal in the coal box 1 is poured out from the bottom of the coal box 1, so that the coal unloading work is completed.
When the bottom plate 13 rotates downwards, the second connecting rod 22 is driven to move downwards, so that the first connecting rod 21 rotates around the rotation axis of the second connecting rod, namely, one end close to the first telescopic rod 41 rotates upwards, so that the first telescopic rod 41 is driven to shrink and reset, the first telescopic rod 41 shrinks, oil in the first rodless cavity 412 is extruded into the second rodless cavity 522 through the first connecting pipe 53, and then flows back to the oil tank 42 through the oil return pipe 421.
When the first telescopic rod 41 is contracted, the movable end of the first telescopic rod 41 is gradually far away from the elastic member 63, the elastic member 63 is reset under the action of self elastic force, the volume in the elastic member 63 is increased, the third telescopic rod 61 is extended under the action of the first spring 62, and part of oil in the third rod cavity 611 flows back to the elastic member 63 by extrusion through the second communicating pipe 64. Since the oil in the fourth rodless chamber 712 is pressed when the operator pulls the pull rod 73 to retract the fourth telescopic rod 71, the oil enters the third rod-shaped chamber 611 through the third communication pipe 74 to further retract the third telescopic rod 61, and thus the first communication pipe 53 is still in the communication state.
After the coal unloading is completed, the operator sends the pull rod 73, under the action of the third spring 72, the fourth telescopic rod 71 extends and resets, so that two ends of the oil return pipe 421 are in an isolated state, at this time, as the volume in the fourth rodless cavity 712 increases, the oil left in the third rod cavity 611 can enter the fourth rodless cavity 712 through the third communicating pipe 74, the third telescopic rod 61 extends, two ends of the first communicating pipe 53 are in an isolated state, and the reset is completed, so that the next coal loading and coal unloading can be performed.
The implementation principle of the self-unloading structure at the bottom of the coal transporting container is as follows:
when the coal box 1 is charged with coal, the bottom plate 13 is driven to be closed by the closing component 2 in an upward rotating mode around the hinge axis of the bottom plate 13 and the frame 11, and then the bottom plate 13 and the frame 11 are fixed by the self-locking component 3, so that the coal box 1 can be charged with coal. In this process, the self-locking assembly 3 is ensured to start to work to fix the bottom plate 13 and the frame 11 after the bottom plate 13 is turned to be closed by the adjusting assembly 6.
When the coal box 1 is unloaded, the two ends of the oil return pipe 421 are controlled to be in a communication state through the control component 7, so that the self-locking component 3 is used for canceling fixation of the bottom plate 13 and the frame 11, the bottom plate 13 is rotated downwards to be opened under the action of gravity of coal in the coal box 1 and the bottom plate 13, and coal in the coal box 1 is poured downwards to finish the coal unloading operation.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
