[0029] As shown in Figures 1-4 , the upper end surface of the threaded seat 4 is fixedly connected with the touch rod 22, the inner top wall of the fixed frame 1 is fixedly installed with the control switch 23, and the control switch 23 and the servo motor 3 are electrically connected through the wire 24. When the threaded seat 4 rises to the specified position, the touch rod 22 will touch the control switch 23, and then control the servo motor 3 to close in time through the wire 24; through the cooperation of the touch rod 22 and the control switch 23, the servo motor 3 is closed in time, and the excessive feeding and waste of materials are avoided.

[0030] As shown in Figures 1-4 , the reset structure specifically includes the vertical rod 19 and the spring two 20 and other components. The vertical rod 19 is fixedly connected between the two end walls of the rectangular through slot two 16, and the spring two 20 is sleeved on the periphery of the vertical rod 19. The upper end of the spring two 20 is fixedly connected to the end wall of the rectangular through slot two 16, and the lower end is fixedly connected to the upper end surface of the U-shaped rod 18. When the limiting plate 15 moves down, the spring two 20 will be compressed; when the external force disappears, the spring two 20 will release energy, push the limiting plate 15 to move up and reset; through the design of the reset structure, the automatic reset of the limiting plate 15 is realized, and the stability and reliability of the device are improved.

[0031] As shown in Figures 1-4 , the lower end of the two limiting plates 15 is fixedly connected with the treading plate 21 for treading to make the two limiting plates 15 descend at the same time. In addition, the inner top wall and the inner bottom wall of the fixed frame 1 are further fixedly connected with the guide vertical rod 25, and the guide vertical rod 25 passes through the threaded seat 4 design.

[0032] As shown in Figures 1-4As shown, one end of the spring 10 is fixedly connected to the end wall of the strip-shaped installation groove 8, and the other end is fixedly connected to the end surface of the sliding sleeve block 11. When the pushing plate 6 is subjected to external force, the L-shaped connecting rod 12 and the sliding sleeve block 11 will slide in the strip-shaped installation groove 8, thereby compressing or stretching the spring 10.

Through the design of the spring 10, the automatic resetting function of the pushing plate 6 during reciprocating movement is realized, and the stability and reliability of the device are improved.

[0033] The working principle of the utility model is as follows: firstly, the servo motor 3 is started, and the output end drives the threaded rod 2 to rotate. Since the threaded rod 2 is rotatably connected to the fixed frame 1 through a bearing, and the threaded seat 4 is threadedly sleeved on the periphery of the threaded rod 2, the rotation of the threaded rod 2 will drive the threaded seat 4 to move up and down along the threaded rod 2. The side edge of the threaded seat 4 is fixedly connected with the feeding placement plate 5, so the feeding placement plate 5 will also move with the up and down movement of the threaded seat 4, realizing automatic feeding of materials.

[0034] When the feeding placement plate 5 moves to the specified position, the materials on its surface need to be pushed into the blast furnace. At this time, the two limiting plates 15 can be simultaneously lowered by stepping on the stepping plate 21. The lowering of the limiting plate 15 will drive the slope 17 on it to contact and push the pushing plate 6 to slide along the surface of the feeding placement plate 5. At the same time, since the limiting plate 15 is inserted into the rectangular through groove I 14, and the rectangular through groove II 16 passes through the U-shaped rod 18, the lowering of the limiting plate 15 will also compress the spring II 20. The sliding of the pushing plate 6 will drive the L-shaped connecting rod 12 and the sliding sleeve block 11 to slide in the strip-shaped installation groove 8, thereby compressing the spring I 10. After the pushing plate 6 pushes the materials into the blast furnace, the pushing plate 6 and the limiting plate 15 will be reset to the initial position respectively due to the elastic restoring force of the spring I 10 and the spring II 20. At this time, the stepping plate 21 can be released, and the spring II 20 will release energy to push the limiting plate 15 to move upward and reset.

[0035] In addition, in order to control the timely closing of the servo motor 3, the utility model also fixedly connects a touch rod 22 to the upper end surface of the threaded seat 4, and fixedly installs a control switch 23 on the inner top wall of the fixed frame 1. When the threaded seat 4 rises to the specified position, the touch rod 22 will touch the control switch 23, thereby controlling the servo motor 3 to close in time through the wire 24, avoiding excessive feeding and waste of materials.

[0036] During the whole working process, the guide vertical rod 25 plays a role in preventing the threaded seat 4 from rotating with the threaded rod 2, ensuring the stable movement of the feeding placement plate 5. At the same time, the cooperation of the reciprocating assembly and the limiting mechanism realizes the reciprocating movement and limiting function of the pushing plate 6 on the feeding placement plate 5, improving the accuracy and stability of feeding.

[0037] The above merely describes the preferred embodiments of the present utility, it should be pointed out that for those skilled in the art, without departing from the principles of the present utility, a number of improvements and refinements can also be made, which should be considered as the protection scope of the present utility.
