[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 As shown, this utility model is a rapid pollination device for increasing the yield of silage corn, including a base 1. A fan 2 and a support 3 are fixedly connected to the top of the base 1. Two supports 3 are symmetrically arranged along the center of the base 1. An air bag 4 is fixedly connected to the outer side of each support 3. An adjustment mechanism 5 is provided on the air bag 4. A folding mechanism 6 is movably connected between the adjustment mechanism 5 and the support 3. Two folding mechanisms 6 are provided. The adjustment mechanism 5 includes a toothed rod 51 and a sleeve rod 52. The toothed end of the toothed rod 51 is slidably connected inside the sleeve rod 52. An adjustment port 53 is provided through the sleeve rod 52. A U-shaped plate 54 is fixedly connected to the sleeve rod 52. A worm 55 is rotatably connected to the inside of the U-shaped plate 54. The worm 55 meshes with the rack 51. A first bevel gear 56 is fixedly connected to one end of the worm 55. A gear shaft 57 is rotatably connected between the U-shaped plate 54 and the sleeve rod 52. A second bevel gear 58 is fixedly connected to the gear shaft 57. The first bevel gear 56 and the second bevel gear 58 mesh. One end of the gear shaft 57 passes through the U-shaped plate 54 and is fixedly connected to a crank handle 59.

[0026] The crank handle 59 is rotatably connected to the U-shaped plate 54.

[0027] Rotating the crank 59 sequentially drives the first bevel gear 56, the second bevel gear 58, and the worm gear 55 to rotate, thereby moving the rack 51. This achieves the adjustment of the device width, adapting to different planting widths and avoiding pollination omissions or plant damage caused by repeated pollination due to mismatched planting widths.

[0028] The folding mechanism 6 includes a rotating frame 61, an anti-rotation frame 62, and a pin assembly 63. The rotating frame 61 is fixedly connected to the bottom of the sleeve rod 52, and the anti-rotation frame 62 is fixedly connected to the outside of the bracket 3. A through hole 64 is provided on one side of the rotating frame 61, and a slot 65 is provided on the other side of the rotating frame 61. There are two of each of the through hole 64 and slot 65. The anti-rotation frame 62 is rotatably connected to the inside of the rotating frame 61 through a rotating shaft 66, and the pin assembly 63 is movably connected to the anti-rotation frame 62.

[0029] The two slots 65 correspond to the two sockets 64 respectively, and the two sockets 64 are at a 90° angle to the rotating shaft 66.

[0030] The pin assembly 63 includes a pin 631, one end of which passes through the anti-rotation frame 62 and the insertion hole 64 and extends to the outside of the rotating frame 61. A limit block 632 is fixedly connected to the pin 631, and a spring 633 is sleeved on the pin 631. Both the spring 633 and the limit block 632 are located inside the anti-rotation frame 62.

[0031] The insertion rod 631 is slidably connected to the anti-rotation bracket 62 and the insertion hole 64 respectively.

[0032] Move the insertion rod 631 towards the handle end, which in turn drives the rotating frame 61 to rotate via the sleeve rod 52. When the insertion hole 64 aligns with the insertion rod 631, moving the insertion rod 631 in the opposite direction will fix the position of the sleeve rod 52, thereby controlling the folding and unfolding of the device. This facilitates the storage and handling of the device, avoiding damage caused by storage difficulties.

[0033] Airbags 4 are fixedly connected to both racks 51. One end of the airbag 4 is fixedly connected to one side of the bracket 3. An air inlet pipe 7 is fixedly connected between the airbag 4 and the fan 2. The air inlet pipe 7 is snapped onto the outside of the bracket 3.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] The working principle of this utility model is as follows: When the width of the device needs to be adjusted, rotating the crank handle 59 drives the gear shaft 57 and the second bevel gear 58 to rotate. Through the meshing relationship, the first bevel gear 56 and the worm gear 55 are driven to rotate, thereby driving the rack 51 to move horizontally within the sleeve 52 through the adjustment port 53, thus adjusting the width of the device. This allows the device to adapt to different planting widths and optimizes the pollination operation. When the device needs to be stored, first adjust the device to the minimum width, and then move the insert rod 631 towards the handle of the insert rod 631 to pass through the limiting block 6. 32. Compress the spring 633 to disengage it from the insertion hole 64. Then, rotate the sleeve rod 52 to drive the rotating frame 61 to rotate around the pivot 66 towards the support 3. When another insertion hole 64 corresponds to the insertion rod 631, reverse the movement of the insertion rod 631 to insert it into the corresponding insertion hole 64. The spring 633 pushes the limit block 632 and the insertion rod 631, fixing the rotating frame 61 and the anti-rotation frame 62, thereby folding the device up. Similarly, the reverse operation can unfold the device, making it easy to store and avoid damage caused by storage difficulties.
