[0033] Example

[0034] Reference Figures 1-5 According to one embodiment of the present invention, a coal bunker coal removal device is provided, which includes a housing 101, a feed pipe 102 disposed outside the housing 101 and connected to the housing 101, a filter plate 103 horizontally fixedly disposed inside the housing 101, filter holes 104 uniformly disposed on the filter plate 103, a motor 105 fixedly disposed through the housing 101, a mounting bracket 106 fixedly connected to the inner wall of the housing 101, a rotating unit 200 driven by the motor 105, a crushing unit 300 and a striking unit 400 driven by the rotating unit 200, a driven unit 500 driven by the crushing unit 300, and a sealing unit 600 driven by the crushing unit 300. The housing 101 is hollow inside and has a discharge port at the bottom.

[0035] The rotating unit 200, crushing unit 300, striking unit 400, driven unit 500 and sealing unit 600 are all located inside the housing 101.

[0036] Furthermore, the rotating unit 200 includes a worm gear 201 fixedly connected to the output end of the motor 105, a turbine 202 connected to the worm gear 201, a first gear 203 driven to rotate by the turbine 202, a first half gear 204 coaxially arranged with the first gear 203, a second gear 205 axially connected to the mounting bracket 106, and a second half gear 206 coaxially arranged with the second gear 205, wherein the first half gear 204 and the second half gear 206 do not come into contact during rotation.

[0037] The turbine 202 is axially connected to the mounting bracket 106, the first gear 203 is axially connected to the side wall of the mounting bracket 106, the first half gear 204 is fixedly connected to the side wall of the first gear 203, the first gear 203 is meshed with the second gear 205, and the first half gear 204 and the second half gear 206 are located in the same vertical plane.

[0038] It should be noted that the starting motor 105 rotates in one direction, which drives the turbine 202 to rotate through the worm gear 201. The turbine 202 drives the first gear 203 to rotate. The first gear 203 synchronously drives the second gear 205 and the first half gear 204 to rotate. The rotation of the second gear 205 drives the second half gear 206 to rotate.

[0039] Furthermore, the crushing unit 300 includes a limiting inclined block 301 fixedly and vertically disposed on the side wall of the mounting frame 106, a lifting plate 302 that moves vertically along the limiting inclined block 301, a crushing plate 303 fixedly connected to the lower end of the lifting plate 302, a vertical rack 304 fixedly disposed on the side wall of the lifting plate 302, a fixing block 305 fixedly connected to the side wall of the lifting plate 302, and a side extrusion assembly 306 driven by the fixing block 305.

[0040] The vertical rack 304 can mesh with the first half gear 204 and the second half gear 206.

[0041] It should be noted that, with the cooperation of the first half gear 204, the second half gear 206 and the vertical rack 304, the lifting plate 302 can be driven to move vertically up and down along the limiting inclined block 301, so as to realize the function of crushing and squeezing the coal blocks in the coal bunker by the lifting and lowering of the crushing plate 303, thereby reducing the possibility of coal blockage.

[0042] Furthermore, two sets of side extrusion components 306 are provided and are symmetrically arranged along the axis of the fixing block 305;

[0043] The side extrusion assembly 306 includes a connecting rod 306a fixedly connected to a fixed block 305 at one end, a fixed plate 306b fixedly connected to the connecting rod 306a, an S-shaped limiting groove 306c passing through the fixed plate 306b, a horizontal rod 306d that moves horizontally through the S-shaped limiting groove 306c, and a side extrusion plate 306e fixedly connected to one end of the horizontal rod 306d. The inner wall of the housing 101 is provided with a limiting block, so that the horizontal rod 306d can only drive the side extrusion plate 306e to move horizontally.

[0044] The lower surface of the side extrusion plate 306e is in contact with the upper surface of the filter plate 103.

[0045] It should be noted that during the vertical downward crushing process of the crushing plate 303, the two side crushing plates 306e move towards each other, realizing multi-sided simultaneous crushing of the coal block, further reducing the possibility of coal blockage.

[0046] Furthermore, the striking unit 400 includes a horizontal transmission rod 401 fixedly connected at one end to the second half gear 206, a first transmission wheel 402 fixedly connected at one end to the horizontal transmission rod 401, a vertical frame rod 403 fixedly connected to the upper surface of the filter plate 103, a second transmission wheel 404 axially connected to the vertical frame rod 403, a transmission belt 405 connecting the first transmission wheel 402 and the second transmission wheel 404, a horizontal fixing rod 406 fixedly connected at both ends to the vertical frame rod 403, and a vertical frame rod 405 fixedly connected to the upper surface of the filter plate 103. The frame rod 403 is axially connected to a driven plate 407, a first straight groove 408 and a second straight groove 409 are provided through the driven plate 407, a rotating transmission rod 410 is fixedly connected to the second transmission wheel 404, a first slider 411 is driven by the rotating transmission rod 410 and moves along the first straight groove 408, a second slider 412 moves along the second straight groove 409, and a striking assembly 413 is driven by the second slider 412. The second straight groove 409 is located above the first straight groove 408.

[0047] It should be noted that the rotation of the second half gear 206 drives the first transmission wheel 402, which in turn drives the second transmission wheel 404 to rotate via the transmission belt 405. The second transmission wheel 404 then drives the first slider 411 to move within the first straight groove 408 via the rotating transmission rod 410, thereby enabling the driven plate 407 to reciprocate in a plane with the shaft connection point with the vertical frame rod 403 as the center.

[0048] Furthermore, the striking assembly 413 includes a rotating block 413a axially connected to the vertical frame rod 403, a rotating block 413a driven to rotate by the second slider 412, a movable rod 413b movably passing through the rotating block 413a, an L-shaped connecting block 413c fixedly connected to one end of the movable rod 413b, a first spring 413d fixedly connected to the lower surface of the L-shaped connecting block 413c at one end, a T-shaped sleeve block 413e sleeved on the horizontal fixed rod 406, a driven block 413f sleeved on the T-shaped sleeve block 413e, and a striking rod 413g fixedly connected to the lower surface of the driven block 413f.

[0049] The other end of the first spring 413d is fixedly connected to the inner wall of the rotating block 413a. The first spring 413d is wound around the movable rod 413b, and the driven block 413f and the L-shaped connecting block 413c are axially connected.

[0050] It should be noted that during the reciprocating oscillation of the driven plate 407, the second slider 412 slides along the second straight groove 409, causing the rotating block 413a to rotate around the shaft connection point with the vertical frame rod 403. During the rotation of the rotating block 413a, the first spring 413d alternates between compression and tension, causing the movable rod 413b to slide vertically along the rotating rod. With the cooperation of the L-shaped connecting block 413c and the T-shaped sleeve block 413e, the driven block 413f drives the striking rod 413g to move horizontally along the horizontal fixed rod 406, and moves vertically downward when it reaches the maximum displacement at both ends, realizing the multi-point striking effect on the filter plate 103, further reducing the possibility of coal blockage.

[0051] Preferably, the multi-sided crushing of coal blocks inside the housing 101 and the multi-point impact on the filter plate 103 can be achieved with only a single rotation of the motor 105, greatly reducing the possibility of coal blockage.

[0052] Furthermore, the driven unit 500 includes a U-shaped connecting rod 501306a that connects two L-shaped connecting blocks 413c simultaneously, a vertical rod 502 fixedly connected to one end of the U-shaped connecting rod 501306a, a first inclined block 503 fixedly connected to the other end of the vertical rod 502, a second inclined block 504 driven to move horizontally via a movable rod 413b, a driven rod 505 fixedly connected to one end of the second inclined block 504, a horizontal rack 506 fixedly connected to the other end of the driven rod 505, a mounting plate 507 fixedly connected to the lower surface of the filter plate 103, two second springs 508 connecting the second inclined block 504 and the mounting plate 507, and a rotating assembly 509 driven by the horizontal rack 506, wherein the first inclined block 503 and the second inclined block 504 do not disengage and always remain in contact;

[0053] The filter plate 103 is movably inserted through the vertical rod 502.

[0054] Furthermore, the rotating assembly 509 includes a third gear 509a disposed above and meshing with the horizontal rack 506, and two connecting rods 509b and two fourth gears 509c symmetrically arranged with the center of the third gear 509a as the axis.

[0055] The two connecting rods 509b are connected to a fourth gear 509c and a third gear 509a at their respective ends.

[0056] Furthermore, the sealing unit 600 includes two L-shaped pads 601 fixedly connected to the lower surface of the filter plate 103, a notch limiting cylinder 602 fixedly connected to the L-shaped pads 601, a lifting rod 603 that rises and falls vertically along the notch limiting cylinder 602, a sealing plate 604 that connects the two lifting rods 603, and sealing blocks 605 evenly disposed on the upper surface of the sealing plate 604, wherein the sealing blocks 605 and the filter holes 104 are sized to match.

[0057] The middle part of the lifting rod 603 is serrated and meshes with the fourth gear 509c, wherein the meshing point is located at the notch of the notch limiting cylinder 602.

[0058] Furthermore, each sealing block 605 is directly opposite a filter hole 104.

[0059] It should be noted that during the downward movement of the first inclined block 503, it squeezes the second inclined block 504, and the two second springs 508 are tensioned. The second inclined block 504 drives the driven rod 505 and the horizontal gear to move linearly. The horizontal rack 506 drives the third gear 509a to rotate, and simultaneously drives the fourth gear 509c to rotate. The two fourth gears 509c simultaneously drive the two lifting rods 603 to move vertically up and down along the notch limiting cylinder 602, further driving the vertical movement of the sealing plate 604. The sealing block 605 blocks the filter hole 104, reducing the engagement of coal blocks with the filter plate 103 during the crushing process, and further reducing the possibility of coal blockage.

[0060] Preferably, during the crushing and compression of the coal blocks inside the housing 101, the engagement of the sealing block 605 and the filter hole 104 reduces the likelihood of coal blockage by preventing the coal blocks from engaging with the filter plate 103 during the crushing and compression process.

[0061] In use, this invention includes three usage states:

[0062] In the first operating state, the coal blocks inside the housing 101 are subjected to multi-sided crushing and extrusion. Specifically, the motor 105 is started to rotate, which drives the turbine 202 to rotate via the worm gear 201. The turbine 202 drives the first gear 203 to rotate, which in turn drives the second gear 205 and the first half gear 204 to rotate. The rotation of the second gear 205 drives the second half gear 206 to rotate. Furthermore, the first half gear 204 drives the vertical rack 304 to lift the plate 302 along the limiting inclined block 30. The vertical downward movement of the lifting plate 302 drives the crushing plate 303 to move vertically downward, thereby achieving vertical compression of the coal blocks inside the box. On the other hand, the lifting plate 302 simultaneously drives the fixing block 305 to move vertically downward, and the fixing block 305 drives the connecting rod 306a and the fixing plate 306b to move vertically downward. The two horizontal rods 306d respectively drive the two side compression plates 306e to move horizontally in opposite directions along the corresponding S-shaped limiting through grooves 306c, thereby achieving the effect of multi-sided compression and crushing of the coal blocks inside the box 101.

[0063] In the second operating state, the filter plate 103 is subjected to multi-point tapping. Specifically, the rotation of the second half gear 206 drives the first transmission wheel 402, which in turn drives the second transmission wheel 404 via the transmission belt 405. The second transmission wheel 404, through the rotation of the transmission rod 410, drives the first slider 411 to move within the first straight groove 408. The driven plate 407 oscillates in a plane around the axis of its connection with the vertical frame rod 403. During the reciprocating oscillation of the driven plate 407, the second slider 412 moves along the second straight groove 409. The sliding motion causes the rotating block 413a to rotate around the axis of its connection with the vertical frame rod 403. During the rotation, the first spring 413d alternates between compression and tension, causing the movable rod 413b to slide vertically along the rotating rod. The driven block 413f, in cooperation with the L-shaped connecting block 413c and the T-shaped sleeve block 413e, drives the striking rod 413g to move horizontally along the horizontal fixed rod 406, and then moves vertically downward when it reaches the maximum displacement at both ends, thus achieving the effect of multi-point striking of the filter plate 103.

[0064] In the third usage state, the filter hole 104 is sealed. Specifically, as the L-shaped connecting block 413c moves downward, it drives the vertical rod 502, which is fixedly connected to the U-shaped connecting rod 501306a, to move downward synchronously. The vertical rod 502 drives the first inclined block 503 to move downward, and as the first inclined block 503 moves downward, it squeezes the second inclined block 504. The two second springs 508 are stretched, and the second inclined block 504 drives the driven rod 505 and the horizontal gear to move linearly. The horizontal rack 506 drives the third gear 509a to rotate, and simultaneously drives the fourth gear 509c to rotate. The two fourth gears 509c simultaneously drive the two lifting rods 603 to rise vertically along the notch limiting cylinder 602, which drives the sealing plate 604 and the sealing block 605 to move vertically upward, thereby sealing the filter hole 104.

[0065] In summary, the beneficial effects of the coal bunker coal removal device of the present invention are that it can achieve multi-sided crushing of coal blocks inside the box 101 and multi-point impact on the filter plate 103 with only a single rotation of the motor 105, which greatly reduces the possibility of coal blockage. Furthermore, it can automatically seal the filter holes 104 during the crushing of coal blocks inside the box, reducing the jamming between coal blocks and the filter plate 103, and further reducing the possibility of coal blockage.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
