[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figure 1-2A wheat sowing device comprises a silo 1, a first wheel 2 installed on the silo 1, a feeding pipe 4 located below the silo 1, a furrow opener 3 located in front of the feeding pipe 4, a blowing hole 5 is opened on the side of the feeding pipe 4, an air storage box 10 is dragged by a pull rod 8 behind the silo 1, a second wheel 14 is arranged at the bottom of the air storage box 10, a pump air component capable of inflating air into the air storage box 10 is connected and installed, an air pressure control valve 7 is installed on the air storage box 10, an air inlet end of the air pressure control valve 7 is connected to the air storage box 10, and an air outlet end of the air pressure control valve 7 is connected to the blowing hole 5 through an air pipe 6.

[0017] The silo 1 is pulled by a tractor to move in the field, and the silo 1 pulls the air storage box 10 to follow the movement. At the same time, the pump air component inflates the air storage box 10, and the gas is transported to the discharge pipe 4 through the air pressure control valve 7 and the air pipe 6. The discharge pipe 4 is unblocked by the air flow, thereby reducing the probability of blockage of the discharge pipe 4, reducing the number of times of manual unblocking of the discharge pipe 4, and reducing the number of shutdowns.

[0018] As an embodiment of the pump air assembly, the pump air assembly includes an air pump and a battery capable of powering the air pump. The air pump and the battery are both installed on the outside of the air storage box 10. The air outlet of the air pump is connected to the air storage box 10, and air is pumped into the air storage box 10 through the air pump.

[0019] As another embodiment of the pump gas assembly, refer to Figure 1 The pump air assembly includes an air cylinder 16 fixed to the air storage box 10, a piston 12 is installed in the air cylinder 16, a chamber is provided between the piston 12 and the air cylinder 16, the chamber is communicated with the air storage box 10, and a one-way air outlet valve 11 is installed between the two, and the air cylinder 16 is provided with a one-way air inlet valve 17 communicated with the chamber, a push-pull rod 15 is installed on the side of the piston 12 away from the chamber, and a connecting rod 13 is rotatably connected to the end of the push-pull rod 15, and an eccentric shaft 24 is eccentrically installed on the second wheel 14, and the connecting rod 13 is rotatably connected to the eccentric shaft 24. When working, when the second wheel 14 rotates, the eccentric shaft 24 is driven to move eccentrically in the vertical plane around the horizontal axis, and the connecting rod 13 is driven to move up and down through the eccentric shaft 24, and the push-pull rod 15 is driven by the connecting rod 13 to push and pull the piston 12 up and down. When the chamber becomes larger, the gas enters the chamber through the one-way air inlet valve 17, and when the chamber becomes smaller, the gas in the chamber enters the air storage box 10 through the one-way air outlet valve 11.

[0020] As an implementation manner, there are four second wheels 14 distributed at the four corners of the bottom of the air storage box 10, there are four air pumping assemblies, and each second wheel 14 corresponds to one air pumping assembly.

[0021] A plurality of air pumping components are arranged to pump air into the air storage box 10, so that the air storage box 10 is pressurized faster and with a higher pressure, and the air blowing from the air blowing hole 5 to the lower material pipe 4 is stronger, and the dredging effect is better.

[0022] In order to prevent the air pressure in the air storage tank 10 from being too high, a pressure relief valve 25 may be provided in the air storage tank 10 , and when the pressure is too high, the pressure is released through the pressure relief valve 25 .

[0023] refer to Figure 2 The air pressure control valve 7 includes a first pipeline 18 fixed and connected to the air storage box 10, a second pipeline 23 is installed at the end of the first pipeline 18, and the second pipeline 23 is connected to the air pipe 6.

A valve plate 19 is fixedly connected to one end of the support rod 20 close to the first pipeline 18. The valve plate 19 can open or close the open end of the first pipeline 18. A limit block 22 is installed at the other end of the support rod 20. A tension spring 21 is connected between the limit block 22 and the second pipeline 23. The tension spring 21 pulls the valve plate 19 to elastically abut against and close the open end of the first pipeline 18. When the air pressure in the air storage box 10 is greater than the tension of the tension spring 21, the gas pushes the valve plate 19 to connect the first pipeline 18 and the second pipeline 23, thereby realizing energy storage in the air storage box 10.

[0024] refer to Figure 1 A spare box 9 with an open top is installed above the gas storage box 10, and the agricultural tools or wheat seeds that can be used can be placed in the spare box 9, so that when the silo 1 has no wheat seeds, it can be more convenient to refill the material.

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
