Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature.

Referring to fig. 1-2, an embodiment of the present application provides an seed dispenser 10. The seed impactor 10 includes a pushing device 200 and a seed cartridge 100. The seed container 100 is used for containing seeds. The seed silo 100 includes an inlet 110 and an outlet 120. The pushing device 200 is used for pushing the seeds in the seed bin 100 through the inlet 110 so as to output the seeds from the outlet 120 one by one. The pushing device 200 can directly push the seeds to be output from the outlet 120 of the seed bin 100. The pressing means 200 may press the seed by pressing the intermediate medium. The intermediate medium may be a gas or a solid component. A plurality of seeds may be placed in the seed hopper 100 at the same time. When the pressing device 200 presses the seeds, only one seed can be output at a time from the outlet 120, and the seeds can be directly dropped to a target sowing position. When a plurality of target sowing positions exist, the seed sowing device 10 is moved above the target sowing positions every time, and then the pushing device 200 pushes and presses one seed to be output, so that the operation is convenient and fast, and the working efficiency is greatly improved.

In one embodiment, the pushing device 200 includes: a gas chamber 220, a piston 230, and a lever 240. One end of the air chamber 220 communicates with the seed chamber 100 through the inlet 110. The piston 230 is disposed at the air chamber 220. The operating rod 240 is connected to the piston 230 and extends from an end of the air chamber 220 remote from the seed cartridge 100. In this embodiment, the air chamber 220 may have a hollow cylindrical or cubic structure. The operating rod 240 may move the piston 230 up and down in the air chamber 220. The piston 230 is capable of squeezing the gas as the gas chamber 220 moves so that the gas pushes the seeds out of the outlet 120. Or the piston 230 moves within the air chamber 220 toward the seed chamber 100 and directly presses the seeds to cause the seeds to be output from the outlet 120. The shape of the piston 230 is adapted to the shape of the inner cross-section of the air chamber 220. It will be appreciated that the area of the piston 230 may be slightly larger than the cross-sectional area of the air chamber 220, thereby ensuring that the piston 230 divides the air chamber 220 into two disconnected parts and preventing air leakage. The lever 240 extends from the end of the air chamber 220 remote from the seed chamber 100, thus facilitating hand depression.

In one embodiment, the air chamber 220 is provided with a shrink tube 210 at an end thereof adjacent to the seed chamber 100. The diameter of the shrink tube 210 is smaller than the diameter of the seed silo 100. The inlet 110 of the seed bin 100 is sleeved on the surface of the shrinkage tube 210 and is communicated with the air chamber 220. The diameter of the shrink tube 210 may be smaller than the diameter of the air chamber 220. Therefore, when the piston 230 moves toward the contraction tube 210 at the air chamber 220, the air pressure is increased due to the cross-sectional area being reduced at the contraction tube 210, and power for pressing the piston 230 can be saved. The seed hopper 100 may be a funnel-shaped structure. The inlet 110 of the seed bin 100 is sleeved on the surface of the shrinkage pipe 210 for convenient matching, so that the installation efficiency can be improved.

In one embodiment, the plenum 220 is integral with the seed silo 100. That is, the air chamber 220 may be in integral communication with the seed chamber 100. The air chamber 220 and the seed chamber 100 may be one piece. In one embodiment, the air chamber 220 is integrally formed with the seed silo 100. Therefore, a part of seeds can be stored in the air chamber 220 to improve the utilization rate. The pushing device 200 may directly contact and push the seed such that the seed is output from the outlet 120.

In one embodiment, the outlet 120 of the seed bin 100 is provided with a barrier 300 for the individual output of seeds. The blocking structure 300 may be designed according to the size and shape of the seeds, so as to press the pushing device 200 in sequence to make the outlet 120 of the seed bin 100 output one seed. The barrier structure 300 may be integrally formed with the seed container 100, or may be a separate component that is mated with the seed container 100.

Referring to fig. 3, in one embodiment, the barrier structure 300 includes a barrier film 310. The barrier film 310 is provided with a notch 311, and when the pushing device 200 pushes the seeds in the seed bin 100, a single seed pushes the notch 311 open and is output from the notch 311. The barrier film 310 may be disposed at the outlet 120 of the seed bin 100 and seal the outlet 120. The cutout 311 may be a linear cutout 311. The incision 311 may be a cross-shaped opening, a multi-dimensional hole or a round small hole according to the shape of the seed. The barrier film 310 may be an elastic material. The incision 311 is thus opened by the seed and the seed is delivered. The cut 311 may be restored to await the output of the next seed. The outlet 120 of the seed bin 100 may be soft, and the diameter of the outlet 120 may be slightly smaller than the diameter of the seeds. Thus, the outlet 120 is deformed by the pressing of the seeds to allow the seeds to pass therethrough while passing through the seeds.

In one embodiment, the barrier 300 includes a hard tapered hole 320. The diameter of the tapered hole 320 is smaller than the diameter of the seed. When the pushing device 200 pushes the seeds in the seed bin 100, the seeds are output after being pushed and deformed through the tapered holes 320. The tapered hole 320 may be formed at the outlet 120 of the seed bin 100. The outlet 120 of the seed bin 100 may be slightly smaller than the diameter of the seed. The tapered hole 320 may be made of a material having a hardness greater than that of the seed, so that the seed may be deformed to a greater extent than the tapered hole 320 when the seed passes through the outlet 120, so that the seed is ejected from the tapered hole 320.

In one embodiment, the seed dispenser 10 further includes an anti-static device 400. The anti-static device 400 is disposed in the seed bin 100. The static electricity preventing means 400 may be a static electricity discharger. The electrostatic discharger may employ a point discharge principle. The static electricity preventing device 400 can prevent the seeds in the seed bin 100 from accumulating static electricity and adhering to the inner wall of the seed bin 100, thereby affecting sowing.

In one embodiment, the end of the operating rod 240 remote from the piston 230 is provided with a pressing member 250. The pressing piece 250 can be pressed to drive the operating rod 240 to push the piston 230 to move. The pressing member 250 may have a pie shape. The area of the pie shape is large, so that the pressure pressing the pressing member 250 is deformed, and the comfort of pressing is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present patent. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
