Description

Technical Field

[0001] The invention belongs to the technical field of cabbage seed sowing, in particular to an air suction sowing device based on cabbage seeds. Background Art

[0002] In the mechanization process of vegetable planting, cabbage, as an important leafy vegetable crop in my country, faces significant challenges in its sowing process due to seed characteristics and agronomic requirements. Cabbage seeds have small particle size (about 1-2mm in diameter), light weight (1,000-seed weight 2-4g) and smooth surface. Traditional mechanical sowing is prone to problems such as missed sowing, repeated sowing or seed damage, resulting in uneven seedling emergence. A large amount of manual thinning and seedling filling is required in the later stage. Manual sowing is not only inefficient (taking 3-5 hours per mu), but also difficult to ensure the accuracy requirements of plant spacing and row spacing (such as plant spacing 20-30cm, row spacing 40-50cm). The aging of power is getting worse, and labor costs are rising year by year (the current cost of manual sowing is about 200-300 yuan / mu). In large-scale planting, the qualified rate of seed holes in traditional mechanical sowing is often less than 70%. The problems of seed waste and seedling competition are prominent. There is an urgent need for automated and precise sowing equipment. Air suction sowing technology uses negative pressure airflow to adsorb seeds. It has the advantages of no seed damage, high precision and significant efficiency. The single-grain adsorption rate can reach more than 95%, and the operating speed can reach 5-8 mu / hour, which is 10-20 times higher than manual efficiency. It can also adapt to different seeds by adjusting the negative pressure, and is suitable for small seeds such as cabbage.

[0003] Most of the existing sowing devices based on cabbage seeds rely on the weight of the seeds to fall, which is prone to causing the sowing spacing to fluctuate due to seed accumulation and uneven friction. In particular, for small-particle cabbage seeds, "clustering" or "missing sowing" occurs, and a large amount of manual thinning is required in the later stage, which is costly and affects the quality of seedlings. At the same time, cabbage seeds are small in size and rough in surface, and are easily formed into an "arch bridge" overhead structure at the discharge hole or the dividing plate due to moisture, static electricity or extrusion, resulting in interruption or uneven sowing. In particular, the risk of blockage increases significantly during high-speed sowing. Therefore, an air suction sowing device based on cabbage seeds is proposed. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention facilitates maintaining uniform sowing spacing by arranging the coordination of structures such as the discharge chute and the discharge hole. The starting motor intermittently aligns the discharge chute on the toothed disc with the discharge hole through transmission, and causes the scraper to stir the seeds in the storage compartment, thereby preventing the seeds from accumulating inside the storage compartment and making it difficult for the seeds to fall. When the discharge chute is aligned with the discharge hole, the seeds above the toothed disc will fall into the guide tube under the action of gravity and the negative pressure in the discharge port, thereby avoiding seed accumulation or missed sowing caused by continuous seed supply. The present invention is particularly suitable for the needs of small-particle and high-density sowing of cabbage seeds, ensuring uniform distribution of seeds between ridges, reducing the cost of manual thinning, ensuring uniform sowing spacing, and realizing uniform and orderly seeding.

[0019] The present invention solves the problem that cabbage seeds are easily blocked by the discharge hole by arranging the cooperation of structures such as the rotating plate and the dividing plate. Through transmission, the rotating plate will rotate in the direction close to the dividing plate under the action of the elastic force of the elastic part and the air pressure in the folded airbag, and finally resist the dividing plate to exert an impact force on the dividing plate to make it vibrate. The vibration effect can effectively destroy the overhead accumulation of seeds on the surface of the dividing plate or near the discharge hole due to the friction between particles, preventing the cabbage seeds from blocking the discharge channel and ensuring smooth seeding. At the same time, the vibration can reduce the adhesion between seeds and the friction with the dividing plate, so that the seeds gathered on the discharge trough or the dividing plate are more easily dispersed into single grains or small groups to fall. Combined with the adsorption effect of the negative pressure of the air suction, the sowing accuracy can be further improved and the phenomenon of multiple grains sticking or missing seeds can be reduced.

[0020] The present invention facilitates the dispersed discharge of seeds by arranging the cooperation of structures such as the divider and the conical block. After the seeds enter the guide tube, they will enter the divider under the transportation of pressurized airflow, and will be evenly distributed and enter the divider tube under the action of the divider, realizing multi-row synchronous sowing and consistent seeding amount in each row, thereby improving the uniformity of field emergence. When the seeds move to the conical block, the conical surface structure of the conical block will force the concentrated falling seeds to radiate and diffuse around, and finally scatter through the discharge port into the furrows plowed by the coulter, avoiding the concentrated discharge of seeds in a single direction. In addition, the surface of the conical block has a smooth transition and a soft airflow speed, which can avoid the seeds from being damaged by hard collision or extrusion, thereby ensuring the seed germination rate.

[0035] A vibration mechanism 2 is provided inside the unloading mechanism 1, and the vibration mechanism 2 includes a second gear 201 and two bevel gears 203. The side of the second gear 201 is meshed with a transmission gear 202, and the bottom of the transmission gear 202 is fixedly connected to the bevel gear 203. The side of the other bevel gear 203 is fixedly connected to a half gear 204. A rotating plate 205 is provided on the side of the half gear 204 away from the second gear 201. A plurality of tooth grooves 206 are evenly provided on the end of the rotating plate 205 close to the half gear 204.

The inner wall of the discharge port 110 is provided with a second rotating groove 209.

[0036] The main mechanism 3 includes a device body 301, a crawler base 302 is provided at the bottom of the device body 301, a GPS navigation 303 is provided on the top of the device body 301, the side of the device body 301 is rotatably connected to an electric cylinder 304 and a rotating bracket 305, and a plurality of plow blades 306 are fixedly connected to the bottom of the rotating bracket 305.

[0037] A sowing mechanism 4 is provided inside the main body mechanism 3, and the sowing mechanism 4 includes a high-pressure fan 401. A guide pipe 402 is fixedly connected to the side of the high-pressure fan 401. A distributor 406 is provided at the end of the guide pipe 402 away from the high-pressure fan 401. Several distribution pipes 403 are provided at the bottom of the distribution pipe 406, and a conical block 404 is fixedly connected to the inner wall of the lower end of the distribution pipe 403.

[0038] The above scheme is adopted: by setting the coordination of structures such as the discharge chute 104 and the discharge hole 108, it is convenient to maintain the uniform sowing spacing, start the motor 101 to rotate the first gear 102 and the toothed disc 103, and the rotation of the toothed disc 103 will cause the toothed disc 103 to rotate. The rotation of the toothed disc 103 will cause the discharge chute 104 on it to be intermittently aligned with the discharge hole 108, and the scraper 105 to stir the seeds in the storage compartment 106 to prevent them from accumulating inside the storage compartment 106 and making it difficult for the seeds to fall. When the discharge chute 104 is aligned with the discharge hole 108, the seeds above the toothed disc 103 will fall into the guide pipe 402 under the action of gravity and the negative pressure in the discharge port 110, avoiding seed accumulation or missed sowing caused by continuous seed supply, which is especially suitable for the small-particle and high-density sowing requirements of cabbage seeds, ensuring uniform distribution of seeds between ridges, reducing the cost of artificial thinning, and ensuring uniform sowing spacing, so as to achieve uniform and orderly sowing;

[0039] By arranging the cooperation of the rotating plate 205 and the dividing plate 107 and other structures, the problem that the cabbage seeds easily clog the discharge hole 108 is solved. The rotation of the second gear 201 will drive the transmission gear 202 meshing with it to rotate. The rotation of the transmission gear 202 will drive the half gear 204 to rotate through the two bevel gears 203, so that it drives the rotating plate 205 meshing with it to rotate through the teeth, so that the end of the rotating plate 205 away from the tooth groove 206 rotates in the direction away from the dividing plate 107, squeezing the elastic member 208 and compressing the air in the folded airbag 207. When the teeth on the half gear 204 rotate to the position of disengaging from the tooth groove 206, the rotating plate 205 will rotate in the direction away from the dividing plate 107. Under the action of the elastic force of the elastic member 208 and the air pressure in the folded airbag 207, it rotates toward the direction of the dividing plate 107, and finally counteracts the dividing plate 107 to exert an impact force on the dividing plate 107, causing it to vibrate. The vibration can effectively destroy the overhead accumulation of seeds on the surface of the dividing plate 107 or near the discharge hole 108 due to the friction between particles, preventing the cabbage seeds from blocking the discharge channel and ensuring smooth seeding. At the same time, vibration can reduce the adhesion between seeds and the friction with the dividing plate, making it easier for the seeds gathered on the discharge trough or the dividing plate to disperse into single grains or small groups to fall. Combined with the adsorption effect of the negative pressure of the air suction, the seeding accuracy can be further improved and the phenomenon of multiple grains sticking together or missing seeds can be reduced.

[0040] like Figures 2 to 5As shown, the rotating plate 205 is rotatably connected between one end close to the half gear 204 and the inner wall of the second rotating groove 209, and the folding airbag 207 is fixedly connected to the inner wall of the second rotating groove 209 on the side away from the rotating plate 205. The inner wall of the folding airbag 207 is elastically connected to the inner wall of the second rotating groove 209 through the elastic member 208. The rotating plate 205 is meshed with the half gear 204 through the tooth groove 206, and the two bevel gears 203 are meshed with each other. The second gear 201 is located below the first gear 102, and the second gear 201 is fixedly connected to the rotating shaft of the first gear 102. The second gear 201 passes through the side of the storage compartment 106 and extends to the inside of the second rotating groove 209. The half gear 204 and the transmission gear 202 are both rotatably connected to the inner wall of the second rotating groove 209, and the end of the rotating plate 205 away from the tooth groove 206 is against the bottom of the dividing plate 107.

[0041] The bottom of the electric cylinder 304 is rotatably connected to the rotating bracket 305, the plow 306 is located at the end of the rotating bracket 305 away from the device body 301, the storage compartment 106 is located above the device body 301, and the bottom of the motor 101 is fixedly connected to the top of the device body 301.

[0042] A discharge port 405 is provided on the plow 306, and the distribution pipe 403 extends from one end away from the distributor 406 to the inside of the discharge port 405. The high-pressure fan 401 is located on the side of the plow 306, and the guide pipe 402 is located below the storage compartment 106. The discharge port 110 at the bottom of the storage compartment 106 is connected to the inside of the guide pipe 402.

[0043] The above scheme is adopted: by setting up the cooperation of structures such as the divider 406 and the conical block 404, it is convenient to disperse the seeds. After the seeds enter the guide tube 402, they will enter the divider 406 under the transportation of pressurized airflow, and are evenly divided and enter the dividing tube 403 under the action of the divider 406, realizing multi-row synchronous sowing and consistent seeding amount in each row, thereby improving the uniformity of field emergence. When the seeds move to the conical block 404, the conical surface structure of the conical block 404 will force the concentrated falling seeds to radiate and diffuse around, and finally scatter through the discharge port 405 in the furrows plowed by the plow 306, avoiding the concentrated discharge of seeds in a single direction, and the smooth transition of the conical block surface and the soft airflow speed can avoid the seeds from being damaged by hard collision or extrusion, thereby ensuring the seed germination rate.

[0044] The working principle and usage process of the present invention are as follows: first, the cabbage seeds to be sown are loaded into the storage compartment 106, and the motor 101 is started to rotate the first gear 102 half a circle. The rotation of the first gear 102 will drive the toothed disc 103 meshing with it to rotate half a circle, so that the discharge chute 104 on it is misaligned with the discharge hole 108 on the dividing plate 107, and the channel of the discharge port 110 is closed. Then, the device is driven to the field to be sown through the crawler base 302, and the rotating bracket 305 is pushed downward by the electric cylinder 304 to rotate downward, driving the plow 306 to be inserted into the field, and the crawler base 302 drives the device to move, and the plow 306 is used to plow the field into furrows;

[0045] Then start the high-pressure fan 401 to deliver high-pressure gas to the guide pipe 402, generate negative pressure inside the discharge port 110, and start the motor 101 at the same time to rotate the first gear 102 and the toothed disc 103. The rotation of the toothed disc 103 will cause the toothed disc 103 to rotate, and the rotation of the toothed disc 103 will cause the discharge chute 104 on it to be intermittently aligned with the discharge hole 108, and cause the scraper 105 to stir the seeds in the storage compartment 106. When the discharge chute 104 is aligned with the discharge hole 108, the seeds above the toothed disc 103 will fall into the guide pipe 402 under the action of gravity and the negative pressure in the discharge port 110, and the rotation of the second gear 201 will drive the transmission gear 202 meshing with it to rotate, and the transmission gear The rotation of the wheel 202 drives the half gear 204 to rotate through the two bevel gears 203, so that the rotating plate 205 meshing with it is driven to rotate through the teeth, so that the end of the rotating plate 205 away from the tooth groove 206 rotates in the direction away from the dividing plate 107, squeezing the elastic member 208 and compressing the air in the folded air bag 207. When the teeth on the half gear 204 rotate to the position of disengaging from the tooth groove 206, the rotating plate 205 will rotate in the direction close to the dividing plate 107 under the action of the elastic force of the elastic member 208 and the air pressure in the folded air bag 207, and finally counteract the dividing plate 107 to exert an impact force on the dividing plate 107, causing it to vibrate, so that the seeds can fall evenly through the vibration;

[0046] After the seeds enter the guide tube 402, they will enter the distributor 406 under the transportation of pressurized airflow, and will be evenly distributed under the action of the distributor 406 and enter the distribution tube 403, realizing multi-row synchronous sowing and consistent seeding amount in each row, thereby improving the uniformity of field emergence. When the seeds move to the conical block 404, the conical surface structure of the conical block 404 will force the concentrated falling seeds to radiate and diffuse around, and finally scatter through the discharge port 405 into the furrows plowed by the plow 306.
