[0002] Agricultural sowing is a key link in agricultural production. Here are some key points about agricultural sowing: Preparation before sowing: Choose the right seeds, considering the adaptability of the variety, resistance to pests and diseases, etc. Finely prepare the land to ensure that the soil is loose and flat. Determine the appropriate sowing time according to the crops and soil conditions. Sowing method: Row sowing: Sow the seeds in the soil in rows at a certain row spacing. Hole sowing: Dig holes and sow at a certain row spacing. Broadcasting: Spread the seeds evenly on the soil surface. Note: Control the sowing depth, different crops have different suitable depths. Maintain sowing uniformity to avoid lack of seedlings or overcrowding. Consider the soil moisture, too dry or too wet may affect emergence. Pay attention to the operating specifications of the seeder to ensure its normal operation. For some seeds that require special treatment, operate according to the requirements. Suppress in time after sowing to promote contact between seeds and soil and facilitate emergence. With the development of agricultural technology, more and more intelligent sowing equipment has been used to improve sowing efficiency and quality.

[0003] During the sowing process, a feeding device is required to discharge the seeds evenly along the feeding pipe so that the seeds can be buried in the soil when the plow head of the seeder turns the ground. The structure of the feeding device of the existing seeder is mostly to set grooves on the surface of a rotating disk so that the rotating disk is circulated in the seed storage bin of the agricultural seeder to complete the feeding. However, with this type of feeding device, it is easy for multiple seeds to enter the grooves on the surface of the rotating disk at one time, which makes the crops too dense and causes certain inconveniences in use.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the embodiments:

[0026] Example 1

[0028] In this embodiment, during the process of replacing the replacement plate 25, the fixing bolt 29 can be rotated, and then the unloading box 210 can be pushed to make the sliding block 28 slide along the sliding groove 27, so as to prevent the unloading box from affecting the replacement of the replacement plate 25. After the replacement is completed, the unloading box 210 is moved back, and the fixing bolt 29 is rotated to fix the sliding block 28, thereby fixing the position of the unloading box 210. The arrangement of the assembly block 42 and the assembly sleeve 44 enables multiple unloading mechanisms 2 to be assembled according to different needs, making it easier to use.

[0029] Example 2

[0030] like Figure 1-9 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the inner wall of the seed storage bin 21 of the agricultural seeder is fixedly connected with a sliding groove 27, the inner wall of the sliding groove 27 is slidably connected with a sliding block 28, one side of the sliding block 28 is fixedly connected with a discharge box 210, the top of the sliding block 28 is threadedly connected with a fixing bolt 29, the surface of the fixing bolt 29 overlaps the surface of the sliding groove 27, the bottom of the discharge box 210 is fixedly connected with a discharge hose 211, the bottom of the seed storage bin 21 of the agricultural seeder is fixedly connected with a mounting member 212, and the surface of the discharge hose 211 overlaps the inner wall of the mounting member 212.

[0031] In this embodiment, the air in the feed tray 24 is continuously extracted along the exhaust pipe 32 by the blower 31. Under the action of air pressure, the air in the seed storage bin 21 of the agricultural seeder carries the seeds to the surface of the feed tray 24. The single seed can be adsorbed to the surface of the feed tray 24 through the airflow. When the feed tray 24 rotates to carry the seeds to the feed box 210, the feed box 210 pushes the seeds to move upward and blocks part of the suction holes 26, reducing the suction force of the suction holes 26. The seeds fall into the feed box 210 and are discharged along the feed hose 211. When the plowshare turns the ground, they are buried underground. At the same time, by replacing the replacement plate 25 with different sizes of suction holes 26 and adjusting the output power of the blower 31, the feed device can adapt to seeds of different sizes.

[0032] Example 3

[0033] like Figure 1-9 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the driving mechanism 3 includes a blower 31, one side of the blower 31 is fixedly connected to one side of the seed storage bin 21 of the agricultural seeder, an exhaust pipe 32 is fixedly connected to the inner wall of the blower 31, one end of the exhaust pipe 32 is rotatably connected to one end of the driving pipe 23, the inner cavity of the exhaust pipe 32 is communicated with the inner cavity of the driving pipe 23, one side of the seed storage bin 21 of the agricultural seeder is fixedly connected to a mounting plate 33, and the top of the mounting plate 33 is fixedly connected to a motor 34. A small gear 35 is fixedly connected to one end of the rotating shaft of the motor 34, and a large gear 36 is meshed on the surface of the small gear 35. The interior of the large gear 36 is fixedly connected to the surface of the driving tube 23. A protective shell 37 is fixedly connected to one side of the seed storage bin 21 of the agricultural seeder. The assembly 4 includes an assembly unit 41. The structure of the assembly unit 41 is the same as that of the unloading mechanism 2. An assembly block 42 is fixedly connected to one side of the assembly unit 41, and a rubber pad 43 is fixedly connected to the surface of the assembly block 42. An assembly sleeve 44 is fixedly connected to the other side of the assembly unit 41.

[0034] In this embodiment, when in use, the plowshare is installed to the bottom of the mounting part 212, and the seeds are placed in the seed storage bin 21 of the agricultural seeder. When unloading, the motor 34 and the blower 31 are started. Under the action of the motor 34, the small gear 35 drives the large gear 36 to rotate, and then the large gear 36 drives the drive tube 23 to rotate, so that the unloading tray 24 rotates.

[0035] The working principle of the feeding device of the agricultural seeder is described in detail below.

[0036] like Figure 1-9As shown, when in use, the plowshare is mounted to the bottom of the mounting member 212, and the seeds are placed in the seed storage bin 21 of the agricultural seeder. When unloading, the motor 34 and the blower 31 are started. Under the action of the motor 34, the small gear 35 drives the large gear 36 to rotate, and then the large gear 36 drives the driving tube 23 to rotate, so that the unloading tray 24 rotates. During the rotation of the unloading tray 24, the air in the unloading tray 24 is continuously extracted along the exhaust pipe 32 by the blower 31. Under the action of air pressure, the air in the seed storage bin 21 of the agricultural seeder wraps the seeds and sticks to the surface of the unloading tray 24. The single seed can be adsorbed to the surface of the unloading tray 24 through the airflow. When the unloading tray 24 rotates and carries the seeds to the unloading box 210, the seeds are pushed upward under the action of the unloading box 210, and part of the suction holes are blocked. 26, so that the suction force of the suction hole 26 is reduced, the seeds fall into the discharge box 210, are discharged along the discharge hose 211, and are buried in the ground when the plow head turns the ground. At the same time, by replacing the replacement plate 25 with different sizes of suction holes 26 and adjusting the output power of the blower 31, the discharge device can be adapted to seeds of different sizes. During the replacement process, the fixing bolt 29 can be rotated, and then the discharge box 210 can be pushed to make the sliding block 28 slide along the sliding groove 27 to prevent the discharge box from affecting the replacement of the replacement plate 25. After the replacement is completed, the discharge box 210 is moved back, and the fixing bolt 29 is rotated to fix the sliding block 28, thereby fixing the position of the discharge box 210. The arrangement of the assembly block 42 and the assembly sleeve 44 enables it to assemble multiple discharge mechanisms 2 according to different needs, making it more convenient to use.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
