A conveying unit 3 is arranged behind the main body 1, and an anti-jamming member 4 is arranged above the main body 1.

[0020] The first pushing block 24, the second upper pushing block 25 and the third pushing block 26 are connected by a hydraulic rod 21 to realize the synchronous lifting of the pushing blocks. Cooperating with the first step 111, the second step 112 and the third step 113, the tops of the first pushing block 24, the second pushing block 25 and the third pushing block 26 are set to be inclined inwardly and communicate, so that the parts will not fall, thus forming a stepped feeding structure. Through the stepped feeding structure, while realizing intermittent feeding, it effectively prevents material accumulation; through the anti-jamming member 4 arranged above the conveyor belt 35, it is limited that only one part can pass through each time. The accumulated parts will be blocked and dropped by the anti-jamming member 4 and re-enter the feeding chute 13 from the return chute 14, thereby further preventing the equipment from being jammed; through the arranged conveyor, continuous conveying is realized, so that the parts are continuously conveyed into the heat treatment furnace.

[0021] Furthermore, the main body 1 includes a housing 11. The housing 11 is provided with a feeding chute 13, and a support plate 12 is arranged at the bottom of the feeding chute 13.

[0022] Furthermore, the housing 11 further includes a first step 111, a second step 112 and a third step 113. The two ends of the first step 111, the second step 112 and the third step 113 are respectively fixedly connected to the housing 11. The first step 111, the second step 112 and the third step 113 are arranged in a stepped manner from bottom to top in sequence. A return chute 14 is arranged on the outer side of the housing 11, and the return chute 14 communicates with the feeding chute 13.

[0023] It should be emphasized that the feeding unit 2 includes a hydraulic rod 21. The bottom of the hydraulic rod 21 is fixedly connected to a cross bar 22. Both ends of the cross bar 22 are fixed to the outer shell 11. The output end of the hydraulic rod 21 is fixedly connected to a connecting piece 23. The connecting piece 23 is connected to the bottoms of the first pusher block 24, the second pusher block 25 and the third pusher block 26. And the first pusher block 24, the second pusher block 25 and the third pusher block 26 correspond to the first step 111, the second step 112 and the third step 113 respectively.

[0024] It should be emphasized that the conveying unit 3 includes a driving motor 31. The bottom of the driving motor 31 is fixedly connected to a fixing plate 32. The fixing plate 32 is fixedly connected to a first support arm 33. The first support arm 33 is fixedly connected to the outer shell 11. The output end of the driving motor 31 penetrates through the first support arm 33 and is drivingly connected to a conveyor belt 35.

[0026] Working principle: First, place the parts in the feeding chute 13. The inclined pallet 12 causes the parts to slide to the top of the first pusher block 24. Then start the hydraulic rod 21. The hydraulic rod 21 drives the first pusher block 24, the second pusher block 25 and the third pusher block 26 simultaneously through the connecting piece 23. The first pusher block 24 pushes the parts upward to the first step 111. When the second pusher block 25 descends, the parts roll to the top of the second pusher block 25. The second pusher block 25 rises and pushes the parts to the second step 112. When the third pusher block 26 descends, the parts roll to the top of the third pusher block 26. The third pusher block 26 rises and pushes the parts to the third step 113. The parts slide onto the conveyor belt 35 and are driven forward by the conveyor belt 35. The stacked parts are blocked by the anti-jamming part 4 and fall into the return chute 14 and then enter the feeding chute 13 again through the return chute 14.
