[0031] The moving motor 551 is a three-phase asynchronous motor and is connected to an external circuit through a wire; one end of the moving lead screw 552 is rotatably connected to the top of the frame 1 through a fixed block.

[0032] In an embodiment of the present invention, the positioning mechanism 4 includes a positioning box 41 installed at the bottom of the conveying table 2. One side of the positioning box 41 is fixedly connected to a positioning motor 42. One end of the output shaft of the positioning motor 42 is fixedly connected to a bidirectional lead screw 43 through a coupling. A positioning plate 44 is threadedly connected to the surface of the bidirectional lead screw 43. The top of the positioning plate 44 is fixedly connected to a positioning rod 45. The top end of the positioning rod 45 is fixedly connected to a positioning frame 46. A plurality of positioning rollers 47 are rotatably connected inside the positioning frame 46.

[0033] The positioning motor 42 is a three-phase asynchronous motor and is connected to an external circuit through a wire; the bidirectional lead screw 43 rotates inside the positioning box 41.

[0034] In an embodiment of the present invention, symmetric positioning grooves 6 are formed at the top of the positioning box 41. The inner surface of the positioning groove 6 is slidably connected to the surface of the positioning rod 45.

[0035] The positioning groove 6 is used for sliding and limiting the positioning rod 45.

[0036] By starting the positioning motor 42 to drive the bidirectional lead screw 43 to rotate, the rotation of the bidirectional lead screw 43 will cause the positioning plates 44, positioning rods 45, positioning frames 46 and positioning rollers 47 on both sides to slide synchronously towards the opposite sides, so that the positioning rod 45 slides on the inner surface of the positioning groove 6. By adjusting the distance between the positioning rollers 47 on both sides, the centering positioning operation of the packaging bag containing large-grain crops is realized. By providing the positioning mechanism 4, under the drive of the positioning motor 42, the distance between the positioning rollers 47 on both sides can be flexibly adjusted. The plurality of positioning rollers 47 are used to center-position the packaging bag of large-grain crops during the conveying process, thereby preventing the packaging bag from shifting during the conveying process and improving the subsequent palletizing quality.

[0037] In an embodiment of the present invention, an infrared receiver 7 is fixedly connected to the top of the conveying table 2, and an infrared transmitter 8 is fixedly connected to the inner side of the frame 1. The infrared receiver 7 is electrically connected to the infrared transmitter 8.

[0038] There are two sets of infrared receivers 7 and infrared transmitters 8 symmetrically arranged. By setting the infrared receivers 7 and infrared transmitters 8, after the large - granular crop packaging bags are transported to the lower part of the clamping plate 518, the transportation can be automatically stopped, facilitating the subsequent palletizing operation.

[0039] At the same time, the content not described in detail in this specification belongs to the prior art well - known to those skilled in the art.

[0040] During operation, first, start the conveyor table 2 to transport the packaging bags containing large - granular crops. At this time, start the positioning motor 42 to drive the bidirectional lead screw 43 to rotate. The rotation of the bidirectional lead screw 43 will cause the positioning plates 44, positioning rods 45, positioning frames 46 and positioning rollers 47 on both sides to slide synchronously towards the opposite side, so that the positioning rod 45 slides on the inner surface of the positioning groove 6. By adjusting the distance between the two positioning rollers 47, the centering positioning operation of the packaging bags containing large - granular crops is realized. Subsequently, as the conveyor table 2 continuously transports the packaging bags containing large - granular crops, when the two sets of infrared transmitters 8 and infrared receivers 7 simultaneously sense an object, at this time, the conveyor table 2 stops transporting. Synchronously, the moving motor 551 starts. The moving motor 551 drives the moving lead screw 552 to rotate. The rotation of the moving lead screw 552 will cause the fixed block 553 and the sliding frame 511 as a whole to start moving. The sliding frame 511 slides on the top of the frame 1. When the sliding frame 511 slides above the conveyor table 2, at this time, start the lifting cylinder 512 to drive the connecting plate 513, the limiting rod 541 and the equipment box 514 as a whole to slide downwards, so that the limiting rod 541 slides inside the limiting block 542, and the clamping plate 518, the buffer plate 521 and the support rod 519 located below the equipment box 514 slide downwards synchronously. And the support rod 519 will move down to the bottom of multiple conveying shafts on the top of the conveyor table 2. The support rod 519 slides in the gap between adjacent conveying shafts. Therefore, the support rod 519 will be located below the packaging bag at this time. Subsequently, start the driving motor 531 to drive the driving gear 532 to rotate. The rotation of the driving gear 532 will cause the sliding tooth plates 517, the sliding plates 516, the support rods, the clamping plate 518 and the support rod 519 on both sides to slide synchronously towards the opposite side. During this process, the buffer plate 521 will first contact the packaging bag containing large - granular crops, and then compress the buffer spring 522, thereby buffering the clamping force to avoid damaging the crops. And the support rod 519 will support the bottom of the packaging bag. Finally, start the lifting cylinder 512 and the moving motor 551 to drive the equipment box 514 as a whole to reset, and stack the packaging bags of large - granular crops into the placement rack 3.
