Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a precision seeder for small-particle special-shaped seeds. Background Art

[0002] At present, the cultivation of Chinese medicinal materials, fruits and vegetables has been scaled up. However, due to the special shape of the seeds of these crops, the mechanized sowing technology is very backward, and it is mainly based on manual or semi-mechanized operations. Therefore, a precision seeder is needed to sow special-shaped seeds.

[0003] The current precision seeder uses a dividing tray to sow special-shaped seeds. Multiple dividing troughs are arranged on the dividing tray. After the seeds fall into the dividing trough, they are transported downward and fall into the pipeline for transportation. However, the special-shaped seeds are not piled up solidly in the dividing trough. When the precision requirement is high, there will be a certain difference in the sowing amount, which may affect the sowing accuracy. Summary of the invention

[0007] In order to facilitate the extraction of gas in the rotating tube, the exhaust assembly further includes an air pump fixedly arranged on the frame, and the exhaust end of the air pump is fixedly connected to an exhaust pipe, and the exhaust pipe is connected to the rotating tube.

[0008] Preferably, an air pumping ring is fixedly connected to the frame, and the rotating tube is sealingly and rotatably connected in the air pumping ring, and a plurality of circular grooves communicating with the air pumping ring are provided on the rotating tube.

[0009] In order to facilitate the driving of the rotating tube to rotate, further, two pulleys are rotatably arranged on the frame, and the two pulleys are driven by belts, a motor is fixedly connected to the frame, and the output end of the motor is fixedly connected to one of the pulleys, and the other pulley is fixedly connected to the rotating tube.

[0010] Preferably, an air jet pipe is fixedly connected to the frame, and the air jet pipe is sealed and rotatably connected in the rotating tube, the exhaust end of the air pump is fixedly connected to the exhaust pipe, the exhaust pipe is connected to one end of the air jet pipe, and a connecting block connected to the air jet pipe is fixedly connected in the material distribution tray, and a first exhaust port and a second exhaust port are provided on the connecting block, and the second exhaust port matches the air suction port.

[0011] In order to facilitate the seeds in the distribution trough to fall, further, a fixing ring is fixedly connected in the fixed tube, a sliding ring is provided on one side of the fixing ring, and the sliding ring slides in the fixed tube, a tension spring is fixedly connected between the fixing ring and the sliding ring, a striking rod is provided on the sliding ring, a rubber layer is fixedly connected in the fixed tube, and a fitting portion is provided on the rubber layer.

[0012] Preferably, the ventilation unit comprises a breathable mesh fixedly arranged on a fixed tube.

[0013] In order to facilitate striking the breathable mesh, further, a mushroom head is fixedly connected to the striking rod.

[0014] In order to facilitate the limiting of the distribution tray, further, the limiting assembly includes a flow limiting block detachably connected to the storage box, and the flow limiting block matches the distribution tray.

[0015] In order to facilitate the sowing of special-shaped seeds, the sowing mechanism further includes a steel pipe fixed on the frame, a soil shovel is fixedly connected to the steel pipe, and a front guide wheel, a support wheel, a rear guide wheel and a flat soil block are provided on the frame.

[0016] Compared with the prior art, the present invention provides a precision seeder for small-particle special-shaped seeds, which has the following beneficial effects:

[0017] 1. The small-particle special-shaped seed precision seeder drives one of the pulleys to rotate through the motor, and then drives the rotating tube to rotate through the pulley and the belt. The rotating tube drives the dividing plate to rotate in the storage box, and the seeds in the storage box fall into the dividing trough. At the same time, the air is pumped through the air pump to make the rotating tube in a negative pressure state. At this time, the gas in the dividing trough is extracted through the air suction port, so that the seeds in the dividing trough are in a compact state. When the dividing plate rotates to the specified angle, the seeds in the dividing trough fall, and the fallen seeds enter the steel pipe through the connecting hose, and finally enter the planting trough shoveled out by the soil shovel, thereby effectively ensuring that the amount of special-shaped seeds sown each time is consistent, and then effectively preventing the seeds from being loose in the dividing trough and affecting the precision of their planting.

[0018] 2. The precision seeder for small-particle special-shaped seeds discharges the extracted gas into the jet pipe through the exhaust pipe, and the gas in the jet pipe enters the connecting block through the first exhaust port, so that the air pressure in the connecting block gradually increases. When the connecting ring moves to the air suction port on one of the fixed pipes and coincides with the second exhaust port, the gas in the connecting block instantly enters the fixed pipe through the second exhaust port and the air suction port, and the gas blows the seeds in the dividing trough downward, causing them to completely fall into the connecting hose, thereby effectively preventing seeds from remaining in the dividing trough, and thus effectively improving the accuracy of sowing special-shaped seeds.

[0019] 3. In this small-particle special-shaped seed precision seeder, when the gas in the connecting block enters into the fixed tube, the pressurized gas blows the mushroom head and the sliding ring, so that the sliding ring drives the striking rod to move downward. At this time, the striking rod drives the mushroom head to strike the breathable mesh, so that the seeds stuck on the breathable mesh fall off, thereby effectively preventing the residual seeds on the breathable mesh.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The present invention effectively ensures that the amount of irregular seeds sown each time is consistent, thereby effectively preventing the seeds from being loose in the dividing trough and affecting the precision of their planting.

DETAILED DESCRIPTION

[0032] 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 the embodiments.

[0033] Example 1: Reference Figure 1-Figure 10, a precision seeder for small-particle special-shaped seeds, comprising: a frame 1, and also comprising: a plurality of sowing mechanisms, which are arranged on the frame 1; a plurality of storage boxes 2, which are fixedly arranged on the frame 1, and a connecting hose 204 is arranged between the storage box 2 and the sowing mechanism; a cover 201, which is arranged on the storage box 2; a distribution plate 4, which is rotatably arranged in the storage box 2; a rotating tube 3, which is rotatably arranged on the frame 1, and the rotating tube 3 is connected to the distribution plate 4; a plurality of fixed tubes 401, which are fixedly arranged on the distribution plate 4 at equidistant intervals around the circumference; a ventilation unit, which is arranged at one end of the fixed tube 401, and a distribution trough is arranged at one end of the distribution plate 4 close to the ventilation unit; a limiting component for limiting the flow of the distribution trough; a connecting ring 403, which is fixedly arranged between the plurality of fixed tubes 401, and the connecting ring 403 is provided with an exhaust port 404 connected to the fixed tube 401; an exhaust component, which is arranged on the frame 1, and the exhaust component is connected to the rotating tube 3.

[0034] The air extraction component includes an air pump 304 fixedly arranged on the frame 1 , and an air extraction pipe 306 is fixedly connected to the air extraction end of the air pump 304 , and the air extraction pipe 306 is communicated with the rotating tube 3 .

[0035] An air pumping ring 305 is fixedly connected to the frame 1 , and the rotating tube 3 is sealingly and rotatably connected in the air pumping ring 305 . The rotating tube 3 is provided with a plurality of circular grooves 308 communicating with the air pumping ring 305 .

[0036] Two pulleys 301 are rotatably provided on the frame 1 , and the two pulleys 301 are driven by belts 302 . A motor 303 is fixedly connected to the frame 1 , and the output end of the motor 303 is fixedly connected to one of the pulleys 301 , and the other pulley 301 is fixedly connected to the rotating tube 3 .

[0037] When small-particle irregular seeds are sown in a precise manner, the irregular seeds are placed in the storage box 2, and the cover 201 is closed, and the frame 1 is installed on the hydraulic mechanism of the tractor.

[0038] The motor 303 drives one of the pulleys 301 to rotate, and then the pulley 301 and the belt 302 drive the rotating tube 3 to rotate, and the rotating tube 3 drives the dividing plate 4 to rotate in the storage box 2, and the seeds in the storage box 2 fall into the dividing trough. At the same time, air is pumped through the air pump 304 to make the rotating tube 3 in a negative pressure state. At this time, the gas in the dividing trough is extracted through the air suction port 404, so that the seeds in the dividing trough are in a compact state. When the dividing plate 4 rotates to a specified angle, the seeds in the dividing trough fall, and the fallen seeds enter the steel pipe 203 through the connecting hose 204, and finally enter the planting trough shoveled out by the soil shovel 202, thereby effectively ensuring that the amount of special-shaped seeds sown each time is consistent, and then effectively preventing the seeds from being loose in the dividing trough and affecting the precision of their planting.

[0039] Example 2: Reference Figure 1-Figure 10, a precision seeder for small-particle special-shaped seeds, which is basically the same as Example 1, further, an air jet pipe 5 is fixedly connected to the frame 1, and the air jet pipe 5 is sealed and rotatably connected in the rotating tube 3, the exhaust end of the air pump 304 is fixedly connected to the exhaust pipe 307, the exhaust pipe 307 is connected to one end of the air jet pipe 5, and a connecting block 501 connected to the air jet pipe 5 is fixedly connected in the distribution tray 4, and a first exhaust port 502 and a second exhaust port 503 are provided on the connecting block 501, and the second exhaust port 503 matches the air suction port 404.

[0040] The air pump 304 discharges the extracted gas into the air jet pipe 5 through the exhaust pipe 307, and the gas in the air jet pipe 5 enters the connecting block 501 through the first exhaust port 502, so that the air pressure in the connecting block 501 gradually increases, and when the connecting ring 403 moves to the air suction port 404 on one of the fixed pipes 401 and coincides with the second exhaust port 503, the gas in the connecting block 501 instantly enters the fixed pipe 401 through the second exhaust port 503 and the air suction port 404, and the gas blows the seeds in the dividing trough downward, causing them to completely fall into the connecting hose 204, thereby effectively preventing seeds from remaining in the dividing trough, thereby effectively improving the accuracy of sowing special-shaped seeds.

[0045] The sowing mechanism includes a steel pipe 203 fixed on the frame 1, to which a soil shovel 202 is fixedly connected. The frame 1 is provided with a front guide wheel 101, a support wheel 102, a rear guide wheel 103 and a soil block 104.

[0046] The soil is shoveled out of the planting groove by the soil lifting shovel 202, and the seeds fall into the planting groove. The soil is leveled by the rear guide wheel 103 and the leveling soil block 104 to cover the seeds.

[0047] When the gas in the connecting block 501 enters the fixed tube 401, the pressurized gas blows the mushroom head 411 and the sliding ring 408, so that the sliding ring 408 drives the striking rod 410 to move downward. At this time, the striking rod 410 drives the mushroom head 411 to strike the breathable mesh 402, so that the seeds stuck on the breathable mesh 402 fall off, thereby effectively preventing the residual seeds on the breathable mesh 402.
