[0002] The seed braiding machine is an agricultural mechanical equipment, which is mainly used for braiding seeds on a specific weaving band to realize more precise and efficient seeding. The existing seed braiding machine can equidistantly adsorb the seeds in the tray on the surface of the rotatable pneumatic seed releasing turntable, and then a weaving band releasing device is arranged below the turntable to continuously release the weaving band and pass the weaving band through the rope winding device. When the seeds are rotated to the position close to the weaving band on the seed releasing turntable, the seeds are automatically released, so that the seeds fall on the weaving band. Then the weaving band is wound into a rope shape through the rope winding device, and the seeds are wrapped in the rope. However, since the weaving band releasing device on the general seed braiding machine has a limited limiting structure, the seeds may slide off the weaving band when falling from the seed releasing turntable, which is inconvenient. Moreover, the seeds are easy to slide off the weaving band when the weaving band is wound into a rope, which is also inconvenient. SUMMARY

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-4 In the embodiments of the utility model, the weaving belt limiting structure for seed weaving machine comprises:

[0023] The fixed plate 100 can be welded with the machine body, the plurality of guide rollers 200 can guide the seed weaving belt, the limiting mechanism 300 can limit the seed weaving belt, and the extrusion mechanism 400 is located at the other end of the one side of the fixed plate 100. One end of the plurality of guide rollers 200 is rotatably connected to the one end of the one side of the fixed plate 100, the limiting mechanism 300 is located at the one side of the fixed plate 100, the limiting mechanism 300 comprises the U-shaped plate 310, the bottom surface of the U-shaped plate 310 is fixedly connected with the supporting plate, one end of the supporting plate is fixedly connected with the one side of the fixed plate 100, the opposite sides of the U-shaped plate 310 are both provided with the U-shaped frame 320, one arm of the two U-shaped frames 320 is fixedly connected with the connecting plate, the connecting plate is fixedly connected with the supporting rod between the one side of the fixed plate 100, and the extrusion mechanism 400 is located at the other end of the one side of the fixed plate 100.

[0024] Specifically, by welding the fixed plate 100 to the machine body, the U-shaped plate 310 is located below the seed placing disc between the two arms, and then the woven belt is guided to move by the plurality of guide rollers 200, and then the woven belt passes through the limiting mechanism 300, the extrusion mechanism 400 and the rope winding device in turn. When the woven belt passes through the limiting mechanism 300, the woven belt passes through the U-shaped plate 310 and the two arms between the two U-shaped frames 320 in turn, so that the woven belt surface is attached to the two arms and the inner bottom surface of the U-shaped plate 310 and the two U-shaped frames 320, so that the cross section of the woven belt between the two U-shaped frames 320 and the U-shaped plate 310 is U-shaped. Then the seeds on the seed placing disc can naturally fall on the woven belt surface inside the U-shaped plate 310, so as to better receive the seeds falling from the seed placing disc and reduce the falling of the seeds from the woven belt.

[0025] Embodiment one

[0026] As shown in Figures 2-3 In this embodiment, two pump boxes 330 are arranged below the two U-shaped frames 320, and one end of each of the two pump boxes 330 is fixedly connected with one side of the fixed plate 100. Each of the two pump boxes 330 is internally provided with a suction pump, and the air inlet end of each of the two suction pumps is fixedly connected with a plurality of suction pipes 331 through a multi-way connecting piece. One end of each of the plurality of suction pipes 331 on any suction pump is fixedly connected with the two arms of the adjacent U-shaped frame 320, and the inside of each of the plurality of suction pipes 331 on any suction pump is in communication with the inside of the adjacent U-shaped frame 320. The distance between the two arms of any U-shaped frame 320 is greater than the distance between the two arms of the U-shaped plate 310.

[0027] In this embodiment, when the woven belt passes between the two arms of the U-shaped frame 320, the two suction pumps are started to suck the air in the space between the two arms of the adjacent U-shaped frame 320 through the adjacent suction pipe 331. Then the woven belt is manually attached to the two arms of the U-shaped frame 320 to form a U-shaped cross section, and the woven belt blocks the plurality of suction pipes 331. Thus, the plurality of suction pipes 331 adsorb the woven belt passing through the inside of the adjacent U-shaped frame 320 due to the internal negative pressure, and the cross section of the woven belt remains in a U-shaped state. Since the distance between the two arms of the U-shaped frame 320 is greater than the distance between the two arms of the U-shaped plate 310, the bottom surface of the woven belt inside the two U-shaped frames 320 is wider, so as to pull the woven belt inside the U-shaped plate 310 to keep it taut, avoiding the woven belt inside the U-shaped plate 310 from being out of the U-shaped state.

[0028] As shown in Figure 2 and Figure 4 In this embodiment, the extrusion mechanism 400 comprises:

[0029] Two moving plates 410, two L-shaped rods 420 and a clamping rail 430, the adjacent side of each of the two moving plates 410 is fixedly connected with a plurality of U-shaped connecting frames, the two arms of any connecting frame are rotatably connected with a press roller 411, and the side away from each of the two moving plates 410 is provided with a sliding groove, the short arm of each of the two L-shaped rods 420 is rotatably connected with the center of the side away from each of the two moving plates 410, the bottom end of each of the two L-shaped rods 420 is provided with a threaded hole, and the short arm of each of the two L-shaped rods 420 is fixedly connected with an internal thread cylinder 421, the inside of each of the two internal thread cylinders 421 is screwed with a resisting screw 422, and the adjacent end of each of the two resisting screws 422 is rotatably connected with a sliding block 423, and the two sliding blocks 423 are respectively slidably connected in the adjacent sliding grooves, one end of the clamping rail 430 is fixedly connected with one side of the fixed plate 100, one end inside the clamping rail 430 is rotatably connected with an adjusting screw 431, and the other end of the adjusting screw 431 penetrates through the inside of the clamping rail 430, the outer side wall of the adjusting screw 431 is screwed with the inner side wall of the two threaded holes, and the outer side wall of each of the press rollers 411 is fixedly sleeved with a sponge sleeve 412.

[0030] In specific implementation, after the woven belt with a U-shaped cross section carries the seeds, the woven belt passes through the press roller 411 between the two moving plates 410, the user can manually twist the two resisting screws 422 to drive the adjacent sliding blocks 423 to move in the adjacent sliding grooves and resist the rotation of the adjacent moving plates 410, so as to adjust the angle of the two moving plates 410, make the two moving plates 410 in an inclined state or a vertical state, make the woven belt with a U-shaped cross section pass through the press roller 411 between the two moving plates 410 and be extruded by the sponge sleeve 412 on the press roller 411 to be in surface adhesion, wrap the seeds in the woven belt, and make the woven belt bending part be extruded to form a crease, so that the woven belt remains in a surface adhesion state, reduces the situation that the seeds fall off from the woven belt when the seeds and the woven belt are subsequently wound into a rope by the rope winding device, and the user can also control the distance between the two moving plates 410 by rotating the adjusting screw 431 to drive the two L-shaped rods 420 to move towards each other or away from each other, the adjusting screw 431 is a positive and negative tooth screw, which can drive the two L-shaped rods 420 to move towards each other or away from each other when it rotates, and the user can adjust the angle and distance between the two moving plates 410 according to the size of the seeds and the size of the woven belt.
