[0018] Second, in the present invention, the driving assembly causes the jacking platform to swing, and the large ore is moved by the steel rope.

The stirring plate on the mesh cylinder stirs the ore to prevent material accumulation. Small ore passes through the mesh of the mesh cylinder. Since the bottom of the screening box is inclined and the inclination is greater than or equal to the inclination of the mesh cylinder, and the stirring plate hinders the movement of large ore, the small ore passing through the mesh cylinder will first enter the buffer structure along the bottom of the screening box. The small ore directly passes through the mesh structure, while the large ore is hindered by the mesh structure. The small ore first falls into the bottom of the mine car, and the driving component causes the jacking platform to swing. The mine car on the jacking platform swings together with the jacking platform. The small ores are evenly scattered at the bottom of the mine car. When the large ore falls in, the small ore buffers the large ore, thereby further reducing the impact force. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Among them, the buffer structure 5 includes a buffer cylinder 501, which is fixed in the support frame 3. The buffer cylinder 501 has two adjacent sides with uniformly distributed first circular holes, and the other two sides of the buffer cylinder 501 have second circular holes with uniformly distributed. A steel rope 509 is arranged between each first circular hole and the second circular hole directly opposite to it. Multiple steel ropes 509 at the same height and multiple steel ropes 509 at adjacent heights form a mesh structure. A limiting structure and a reset structure are respectively arranged at both ends of the steel rope 509, and the limiting structure and the reset structure on each steel rope 509 are respectively arranged in the first circular hole and the second circular hole where the steel rope 509 is located.

[0037] The technical solution of the present invention is that when the large ore enters the buffer cylinder 501, the large ore contacts the steel rope 509 forming the mesh structure, the steel rope 509 is bent, and the reset structure generates an antagonistic force to apply a straightening force to the steel rope 509, so that the steel rope 509 has the ability to reset, that is, the steel rope 509 has a tendency to be tightened. While the large ore bends the steel rope, the steel rope 509 applies a reaction force to the large ore, so that the impact force of the large ore is reduced, thereby reducing the impact force of the ore on the bottom of the mine car, thereby reducing the loss of the mine car; the driving component causes the lifting platform 102 to swing, and the large ore is pushed by the steel rope 509, so that the large ore has an upward pushing force, which increases the contact time between the large ore and each mesh structure, thereby greatly offsetting the impact force of the ore, and further reducing the impact force of the ore on the bottom of the mine car.

[0038] Specifically, the multiple limiting structures each include a positioning column 503 and a first circular plate 502 fixed on one end of the positioning column 503, the other ends of the multiple positioning columns 503 are fixed one-to-one with one end of the multiple steel ropes 509, and the multiple positioning columns 503 are slidably inserted into the multiple first circular holes.

[0040] Specifically, multiple reset structures include positioning cylinders 506, and multiple positioning cylinders 506 are respectively slidably inserted in each second circular hole, and the outer sides of the multiple positioning cylinders 506 are fixed with circular rings 505 coaxially arranged therewith, and the multiple circular rings 505 are located on the outer sides of the buffer cylinder 501. Sliding columns 508 are slidably inserted in the multiple positioning cylinders 506, and one end of the multiple sliding columns 508 is fixed with a second circular plate 504, and the outer sides of the multiple sliding columns 508 are respectively sleeved with reset springs 507, and the other ends of the multiple sliding columns 508 are respectively fixed one-to-one with the other ends of the multiple steel ropes 509.

[0041] In the present invention, the steel rope 509 is bent, and the reset structure generates an opposing force to apply a straightening force to the steel rope 509. The process is that the steel rope 509 pulls the sliding column 508, and the sliding column 508 moves toward the inside of the buffer cylinder 501. The sliding column 508 compresses the reset spring 507 with the help of the second circular plate 504, and the reset spring 507 generates an opposing elastic force, so that the sliding column 508 applies a straightening force to the steel rope 509.

[0042] Specifically, the driving assembly includes a plurality of electric push rods 108 , and the telescopic ends of the plurality of electric push rods 108 are rotatably mounted on the top of the jacking platform 102 .

[0043] In the present invention, the electric push rod 108 controls the lifting and lowering of the jacking platform 102 in the form of telescoping.

[0044] Specifically, the drive assembly also includes a first servo motor 112 and multiple Z-axis shafts 107, one ends of the multiple Z-axis shafts 107 are rotatably mounted on the surface of the intermediate table 106, and each Z-axis shaft 107 is parallel to each other, the bottom ends of the outer shells of multiple electric push rods 108 are respectively rotatably mounted on the other end of the Z-axis 107, the casing of the first servo motor 112 is fixed on the intermediate table 106, and the output shaft of the first servo motor 112 is coaxially fixed with one end of one of the Z-axis shafts 107.

[0045] In the present invention, the driving component causes the lifting platform 102 to perform a swinging motion. Specifically, the first servo motor 112 drives the Z-axis 107 fixed thereto to rotate through the output shaft. Referring to the principle of the tea kneading machine in the prior art, it can be seen that the lifting platform 102 maintains its original state and performs eccentric rotation, so that the lifting platform 102 performs a swinging rotation.

[0046] Specifically, two mutually parallel parking rails 103 are fixed to the table surface of the lifting table 102;

[0047] In the present invention, the mining car of the prior art is moved onto the parking rails 103 by means of rail wheels.

[0048] Specifically, two notches facing each other are provided on the outer side of the lifting platform 102, and the two notches are located in the middle of the two parking rails 103.

Rotating shafts 110 are rotatably installed inside the two notches, and multiple limiting plates 104 are fixed on the outer sides of the two rotating shafts 110. Gear sleeves 117 coaxially arranged therewith are fixed on the outer sides of the two rotating shafts 110. A tooth plate 116 is provided in each of the two through openings 111, and the two tooth plates 116 are respectively meshed with two gear sleeves 117, and a fixing block 115 is fixed at one end of each of the two tooth plates 116, and a square rod 119 is fixed in each of the two grooves 118. The two fixing blocks 115 are respectively slidably sleeved on the two square rods 119, and one of the electric push rods 108 is located in the middle of the two recesses. An intermediate plate 113 is fixed to the outer side of the electric push rod 108, and connecting rods 114 are rotatably installed at both ends of the intermediate plate 113, and one end of the two connecting rods 114 is rotatably installed on the two fixing blocks 115.

[0049] In the present invention, when the lifting platform 102 is pushed upward by the electric push rod 108, the lifting platform 102 and the electric push rod 108 installed with the middle plate 113 move linearly relative to each other, and the middle plate 113 pulls the two fixed blocks 115 closer to each other through the two connecting rods 114, and the tooth plates 116 on the two fixed blocks 115 move accordingly, and the two tooth plates 116 synchronously shift the two gear sleeves 117, and the gear sleeves 117 drive the rotating shaft 110 fixed thereto to rotate until the limit plate 104 contacts the bottom rail shaft of the mine car, completing the limit, and aligning the mine car with the buffer cylinder 501.

[0050] Specifically, the inner annular surface of the top of the buried platform 101 is an inner conical surface 109 , and the lifting platform 102 is in the shape of an inverted truncated cone as a whole, and the conical surface of the lifting platform 102 is uniformly and movably embedded with balls 105 .

[0051] In the present invention, when each electric push rod 108 retracts, the lifting platform 102 moves downward. When the ball 105 on the lifting platform 102 contacts the inner conical surface 109 of the buried platform 101, the lifting platform 102 is corrected and reset until the lifting platform 102 coincides with the inner conical surface 109 of the buried platform 101.

[0052] Specifically, a separation mechanism 4 is provided on the top of the support frame 3, wherein the separation mechanism 4 includes a screening box 401, the screening box 401 is fixed to the support frame 3, one end of the screening box 401 is away from the buffer cylinder 501 and the end is provided with a rotating hole with a central axis inclined, a mesh cylinder 402 is rotatably installed in the rotating hole, a plurality of stirring plates 407 are fixed inside the mesh cylinder 402, a second servo motor 406 is fixed on the outside of the screening box 401, a first transmission wheel 403 coaxially arranged therewith is fixed on the output shaft of the second servo motor 406, a second transmission wheel 405 coaxially arranged therewith is fixed on one end of the mesh cylinder 402, a transmission belt 404 is jointly sleeved with the first transmission wheel 403 and the second transmission wheel 405, and the bottom of the screening box 401 is inclined, and the inclination is greater than or equal to the inclination of the mesh cylinder 402;

[0053] In the present invention, ore is poured into the mesh cylinder 402, and the second servo motor 406 rotates the first transmission wheel 403 through the output shaft. The first transmission wheel 403 and the second transmission wheel 405 rotate synchronously through the transmission belt 404, and the second transmission wheel 405 drives the mesh cylinder 402 to rotate accordingly. The stirring plate 407 on the mesh cylinder 402 stirs the ore to prevent material accumulation. Small ore passes through the mesh of the mesh cylinder 402. Since the bottom of the screening box is inclined and the inclination is greater than or equal to the inclination of the mesh cylinder 402, the stirring plate 407 hinders the movement of large ore. The small ore passing through the mesh cylinder will first enter the buffer structure 5 along the bottom of the screening box 401. The small ore directly passes through the mesh structure, and the large ore is hindered by the mesh structure. The small ore is evenly scattered at the bottom of the mine car. When the large ore falls in, the small ore buffers the large ore, thereby further reducing the impact force.

[0054] Working principle: the mine car is parked on the parking guide rail 103 and moves roughly to the middle position of the two notches. The electric push rod 108 lifts the jacking platform 102 by extending. When the jacking platform 102 is pushed upward by the electric push rod 108, the jacking platform 102 and the electric push rod 108 installed with the middle plate 113 move in a relative straight line. The middle plate 113 pulls the two fixed blocks 115 closer to each other through two connecting rods 114, and the tooth plates 116 on the two fixed blocks 115 move accordingly. The two tooth plates 116 synchronously shift the two gear sleeves 117, and the gear sleeve 117 drives the rotating shaft 110 fixed thereto to rotate until the limit plate 104 contacts the bottom rail shaft of the mine car, completing the limit, so that the mine car is aligned with the buffer cylinder 501; When the large ore enters the buffer cylinder 501, the large ore contacts the steel rope 509 forming the mesh structure, the steel rope 509 is bent, and the reset structure generates an opposing force to apply a straightening force to the steel rope 509. In this process, the steel rope 509 pulls the sliding column 508, and the sliding column 508 moves toward the inside of the buffer cylinder 501. The sliding column 508 compresses the reset spring 507 with the help of the second circular plate 504, and the reset spring 507 generates an opposing elastic force, so that the sliding column 508 applies a straightening force to the steel rope 509; thereby, the steel rope 509 has the ability to reset, that is, the steel rope 509 has a tendency to be tightened. When the large ore bends the steel rope 509, the steel rope applies a reaction force to the large ore, thereby reducing the impact force of the large ore, thereby The impact force of the ore on the bottom of the mine car is reduced, thereby reducing the loss of the mine car; the driving component causes the lifting platform 102 to swing. Specifically, the first servo motor 112 drives the Z-axis 107 fixed thereto to rotate through the output shaft. Referring to the principle of the tea kneading machine in the prior art, it can be seen that the lifting platform 102 maintains its original state and rotates eccentrically, so that the lifting platform 102 swings and rotates; the large ore is moved by the steel rope 509, and the steel rope 509 applies upward resistance to the large ore, increasing the contact time between the large ore and each mesh structure, thereby greatly offsetting the impact force of the ore, and further reducing the impact force of the ore on the bottom of the mine car; the ore is poured into the mesh cylinder 402, and the second servo motor 406 drives the first transmission wheel through the output shaft 403 rotates, the first transmission wheel 403 and the second transmission wheel 405 rotate synchronously through the transmission belt 404, the second transmission wheel 405 drives the mesh drum 402 to rotate accordingly, the stirring plate 407 on the mesh drum 402 stirs the ore to prevent material accumulation, and the small ore passes through the mesh of the mesh drum 402. Since the bottom of the screening box is inclined and the inclination is greater than or equal to the inclination of the mesh drum 402, combined with the swinging motion, the stirring plate 407 hinders the movement of the large ore, and the small ore first enters the buffer structure 5, and the small ore directly passes through the mesh structure, the large ore is hindered, and the small ore is evenly scattered at the bottom of the mine car. When the large ore falls in, the small ore buffers the large ore, thereby further reducing the impact force.
