[0022] It should be noted that, in combination Figure 1 , Figure 3 and Figure 4As shown, the lower surface of the receiving box 4 is provided with a trapezoidal groove 41, the upper surface of the walking table 3 is provided with a sliding groove 32, the pushing mechanism 5 comprises a screw rod 51 rotatably installed in the sliding groove 32, the outer surface of the screw rod 51 is screw-connected with a push block 52, the push block 52 is slidingly installed in the sliding groove 32 and located in the corresponding trapezoidal groove 41, the left and right surfaces of the push block 52 are arc-shaped at the top, the opposite surfaces of the two walking tables 3 are fixedly installed with screw rod motors 53, the output end of the screw rod motor 53 is fixedly connected with the inner side end of the screw rod 51, when the screw rod motor 53 drives the screw rod 51 to rotate forward or reversely, the push block 52 can be driven to move towards or away from the adapter block 31, so as to lift the receiving box 4 to pour the material, after moving away from the adapter block 31, the push block 52 is located in the trapezoidal groove 41 of the receiving box 4, at this time, the receiving box 4 is reset under the action of its own weight.

[0023] As shown in the figure, Figure 2 The outer surface of the annular track 2 is fixedly installed with an annular rack plate 21, the lower surface of the walking table 3 is fixedly installed with a walking motor 33, the output end of the walking motor 33 is sleeved with a gear 331, the gear 331 is meshingly connected with the annular rack plate 21, the lower surface of the walking table 3 is rotatably installed with four positioning wheels 34, two of the four positioning wheels 34 are arranged on the inner and outer sides of the annular track 2;

[0024] In actual use, the walking motor 33 can be started to rotate, the gear 331 and the annular rack plate 21 are matched to drive the walking table 3 to move, so as to realize the alternate movement of the receiving boxes 4 on the two walking tables 3 to the discharging end of the shearing machine for receiving material, compared with the prior art, the two walking tables 3 drive the respective receiving boxes 4 to alternately displace towards the receiving position, so as to shorten the interval time of receiving material and improve the production efficiency.

[0025] In addition, the lower surface of the walking table 3 is fixedly installed with a lifting box 6, the lifting box 6 is fixedly installed with a storage battery 61, the storage battery 61 is electrically connected with the walking motor 33 and the screw rod motor 53 at the similar position, the upper surface of the walking table 3 is fixedly installed with a PLC programming controller 7 and an infrared positioning controller 8, the rack 1 is fixedly installed with two horizontal scales 11, the horizontal scales 11 are fixedly installed with reflective positioning gratings 9, the positions of the reflective positioning gratings 9 correspond to the positions of the similar infrared positioning controllers 8, the PLC programming controller 7 is electrically connected with the similar storage battery 61, infrared positioning controller 8, walking motor 33 and screw rod motor 53.

Among them, the PLC programming controller 7 plays a key role, on the one hand, it receives the positioning signal from the infrared positioning controller 8, and on the other hand, it controls the walking motor 33 and the screw motor 53 according to the pre-written program, thereby achieving automatic control of the entire device. In the actual application link, combined with Figure 5 When a certain receiving box 4 finishes the receiving work, the PLC programming controller 7 will start the corresponding walking motor 33 according to the preset logic control, prompting the walking motor 33 to drive the corresponding walking table 3 and the receiving box 4 to move synchronously in the clockwise direction. When the infrared positioning controller 8 moves to the reflective positioning grating 9 near the unloading position (the right side of the annular track 2 is the receiving position, and the left side is the unloading position), the infrared projection on the reflective positioning grating 9 will generate a feedback signal, which will be captured by the infrared positioning controller 8 and transmitted to the PLC programming controller 7. Then, the PLC programming controller 7 controls the walking motor 33 to stop running based on the signal, thereby accurately positioning the walking table 3 at the unloading position. Then, the PLC programming controller 7 will control the screw motor 53 to rotate, and the push block 52 will push the receiving box 4 to achieve push-over to complete the unloading operation. After unloading, the receiving box 4 is restored to the initial state. At the same time, another receiving box 4 has completed the receiving task. By pre-setting the control signal of the PLC programming controller 7 at a specific frequency, the automatic continuous operation of the entire receiving device can be realized, effectively improving the work efficiency and accuracy, meeting the production needs.
