DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a stacking mechanism for timely stacking square bundles after bundling, thereby improving work efficiency and reducing the labor intensity of workers.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-7 As shown, this embodiment provides a palletizing mechanism, including a platform structure, a multi-stage hydraulic cylinder 1, a push plate 2, a hydraulic motor, a sprocket 7, a chain and a push rod.

[0034] The platform structure has a transverse groove, one end of which extends to one side edge of the platform structure, and the distance between the other end of the transverse groove and the other side edge of the platform structure is not less than the width of a square bundle. The multistage hydraulic cylinder 1 is fixedly connected to the platform structure, and the push plate 2 is fixed to the telescopic end of the multistage hydraulic cylinder 1. When the multistage hydraulic cylinder 1 is working, the square bundle on the platform structure is pushed longitudinally by the push plate 2. The hydraulic motor is fixedly connected to the platform structure, and the chain is sleeved on the outside of the two sprockets 7 and cooperates with the two sprockets 7. The output shaft of the hydraulic motor is key-connected with one of the sprockets 7, and the other sprocket 7 is rotatably connected with the platform structure, specifically, it is rotatably connected with a fixed shaft through a bearing, and the fixed shaft is fixed on the platform structure. The chain is located directly below the gap, and the push rod is fixed on the outer contour of the chain. When the push rod moves, it can extend upward from the gap without colliding with the platform structure. When the hydraulic motor is working, the push rod is driven to move in the gap through the chain transmission system of the sprocket 7, thereby pushing the square bundle on the platform structure in the horizontal direction.

[0035] When in use, place the platform structure under the square bale machine, and make the square bale of the square bale machine fall on one side of the platform structure, which is the side where the transverse groove extends to the edge of the platform structure. Make the hydraulic motor work, the push rod pushes the first square bale to the transverse edge and then retreats, ready to push the second square bale, so that each square bale can move horizontally in sequence. When the square bales are arranged in a row horizontally, the multi-stage hydraulic cylinder 1 works to push the whole row of square bales longitudinally to the position of the next row. The lower edge of the push plate 2 should be higher than the upper end of the push rod to prevent the two from colliding.

[0036] In order to reduce the occupied space when not in use, the stacking mechanism of this example is a foldable structure. Specifically, the platform structure in this embodiment is a split structure, including a support pin, a push plate platform 8, a sealing plate 4 and a bundle storage platform. The push plate platform 8, the sealing plate 4 and the bundle storage platform have equal height horizontal surfaces for the square bundle to slide, and the sealing plate 4 is installed on the push plate platform 8. A comb tooth structure 42 is provided at the edge of one of the transverse long sides of the sealing plate 4, and a strip notch 51 is provided at the position corresponding to each comb tooth of the comb tooth structure 42 on the bundle storage platform, and the total width of the comb tooth structure 42 is not less than the width of a square bundle.

[0037] The structure of the push plate platform 8 has various forms, and those skilled in the art can choose according to actual needs. In this embodiment, the push plate platform 8 includes a platform reinforcement plate 81, a platform upper vertical plate 82, a platform horizontal plate 83, a platform lower vertical plate 84, a second hanging ear 86 and a sealing plate mounting plate 3. The platform vertical plate 82 is vertically welded and fixed to one long side of the platform horizontal plate 83, and the platform lower vertical plate 84 is vertically welded and fixed to the other long side of the platform horizontal plate 83. The platform vertical plate 82 and the platform lower vertical plate 84 are respectively located on the upper and lower sides of the platform horizontal plate 83. The platform reinforcement plate 81 is a triangular plate, and the two platform reinforcement plates 81 are respectively fixed to the two sides of the platform horizontal plate 83, and one right-angled side of the platform reinforcement plate 81 is welded and fixed to the short side of the platform horizontal plate 83, and the other right-angled side of the platform reinforcement plate 81 is welded and fixed to the short side of the platform lower vertical plate 84, and a plurality of second hanging ears 86 are welded and fixed to the side of the platform lower vertical plate 84 facing the lower vertical plate 6. The sealing plate mounting plate 3 is a parallelogram plate, and two sealing plate mounting plates 3 are respectively located on both sides of the platform transverse plate 83, and each sealing plate 4 mounting plate 3 is fixedly connected to one of the platform reinforcement plates 81 by bolts and nuts. The two bottom sides of the sealing plate mounting plate 3 coincide with the short sides of the upper platform vertical plate 82 and the short sides of the lower platform vertical plate 84, respectively, and the hypotenuse of the sealing plate 4 mounting plate 3 coincides with the hypotenuse of the platform reinforcement plate 81.

[0038] A limiting hole 85 for inserting a support pin is provided on the lower vertical plate 84 of the platform. After the support pin is inserted into the limiting hole 85 , the sealing plate 4 can be supported, thereby improving the bearing capacity of the sealing plate 4 .

[0039] In this embodiment, vertical rods 41 are fixed at both ends of the sealing plate 4, and the vertical rods 41 are perpendicular to the sealing plate 4. The push plate platform 8 is provided with vertical grooves 31 for the vertical rods 41 to be inserted, that is, the vertical rods 41 can slide in the vertical grooves 31. The bundle storage platform includes a fixedly connected horizontal large plate 5 and a lower vertical plate 6. The lower vertical plate 6 is vertically arranged and extends along the horizontal direction of the horizontal large plate 5. The lower vertical plate 6 is fixed to one end of the horizontal large plate 5 close to the push plate platform 8 and is located at the lower side of the horizontal large plate 5. A plurality of first hanging ears 62 are provided on the lower vertical plate 6, and a plurality of second hanging ears 86 are provided on the push plate platform 8. The horizontal positions of the first hanging ears 62 and the second hanging ears 86 correspond to each other one by one and are rotatably connected through a pin shaft. When the lower vertical plate 6 rotates to the vertical position, the first hanging ears 62 and the push plate platform 8 limit against each other. If you want to fold it, pull out the supporting pin, lift the platform horizontal plate 83 slightly, and slide the vertical rod 41 on the sealing plate 4 from the upper part of the vertical groove 31 to the lower part, so that the push plate platform 8 can be rotated to the vertical position, and the multi-stage hydraulic cylinder works to make the push plate 2 and the horizontal large plate 5 collide with each other, thus reducing the longitudinal length and the space occupied.
