[0004] The device in the above-mentioned comparative document cannot accurately control the amount of seeds sown during the sowing process, and may cause excessive sowing and waste of seeds. In order to achieve more accurate sowing, a wheat seeder that reduces the sowing amount and shortens the row spacing is proposed. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a wheat seeder that reduces the sowing amount and shortens the row spacing, which can reduce the sowing amount, improve sowing accuracy, and avoid seed waste.

[0006] To achieve the above object, the application provides the following technical scheme: a wheat seeding machine capable of reducing seeding amount and shortening row spacing, comprising a frame, a seeding mechanism, a soil loosening mechanism and an irrigation mechanism, the seeding mechanism comprises a seed bin fixedly connected to the inner wall of the frame, a rotating shaft rotatably arranged in the inner wall of the seed bin, and a first servo motor fixedly connected to the outer surface of the seed bin, the output shaft end of the first servo motor is fixedly connected to one end of the rotating shaft, the outer surface of the rotating shaft is fixedly connected with a plurality of seed trays, the outer surface of each seed tray is provided with uniformly distributed seed grooves, the inner wall of the seed bin is fixedly connected with two scrapers, the bottom end of the seed bin is provided with uniformly distributed seeding pipes, the other end of the rotating shaft is fixedly connected with a first sprocket, the tail end of the frame is rotatably connected with a drive shaft, the outer surface of the drive shaft is fixedly connected with a second sprocket, the second sprocket is provided with a chain, and the first sprocket is in transmission connection with the drive shaft through the chain.

[0007] Through the above scheme, the rotating shaft can be driven to rotate by starting the first servo motor, and the seeds in the seed bin can fall into the seed grooves on the surface of the seed tray due to their own gravity, and the size of the seed groove can only accommodate one wheat seed, so that one rotation of the seed tray can realize the work of seeding the quantitative wheat seeds, and the first sprocket, the second sprocket and the chain are arranged in cooperation, so that the driving wheel can rotate during the seeding process, thereby realizing the movement of the device, so that the wheat seeds can be accurately seeded in different positions of the farmland, and the row spacing during seeding is short, the planting density per unit area can be improved, and the device is more practical.

[0008] Further, the diameter of the first sprocket is slightly larger than the diameter of the second sprocket, and the surface of the frame is provided with a reserved groove matched with the chain.

[0009] Through the above scheme, by limiting the size relationship between the first sprocket and the second sprocket, the rotation speed of the second sprocket can be slightly greater than that of the first sprocket, so that the effect of shortening the seeding row spacing can be achieved.

[0010] Further, the soil loosening mechanism comprises a soil loosening knife assembly installed at the front end of the frame, and the output shaft end of the second servo motor is fixedly connected to the rotating shaft end of the soil loosening knife assembly.

[0011] Through the above scheme, the soil loosening mechanism can loosen the soil in the farmland, facilitating the subsequent wheat seeding work.

[0012] Further, the irrigation mechanism comprises a water tank fixedly connected to the upper surface of the frame, a spray head connected to the bottom end of the water tank through a liquid pump, and a liquid filling port installed at the top end of the water tank.

[0013] Through the above solution, the farmland where wheat seeds have been sown can be properly watered by setting up the irrigation mechanism, thereby optimizing the actual use effect of the device.

[0014] Furthermore, two symmetrical steering wheels are installed at the front end of the frame, and the loosening knife assembly is located between the two steering wheels.

[0016] Furthermore, a rotatable soil pressing roller is installed on the bottom surface of the frame, and the soil pressing roller is located between the driving wheel and the sprinkler head.

[0017] According to the above solution, the soil pressing roller can be provided to flatten the land where wheat sowing is completed, thereby optimizing the wheat sowing process.

[0018] Furthermore, a bulldozer block is fixedly connected to the bottom surface of the frame, and the bulldozer block is located between the seeding pipe and the loosening knife assembly.

[0019] According to the above scheme, the soil turned over by the loosening knife assembly can be flattened by setting the bulldozer block, which makes it convenient to sow wheat seeds into the farmland through the sowing tube.

[0020] Furthermore, the number of the sowing tubes corresponds to the number of the seed trays, and each sowing tube is located directly below the seed tray.

[0021] According to the above solution, by defining the relationship between the sowing tube and the seed tray, the seeds in the seed groove can be transported to the farmland through the sowing tube for sowing.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] This wheat seeder reduces the sowing amount and shortens the row spacing. By starting the first servo motor, the rotating rod can drive multiple seed discs to rotate, and the seeds in the seed bin will fall into the seed groove on the surface of the seed disc under the action of gravity. It is worth noting that the seed groove is designed to accommodate only one wheat seed. Therefore, each rotation of the seed disc can accurately sow a certain amount of wheat seeds. At the same time, the equipped scraper can effectively remove excess seeds to ensure that only one seed remains in each seed groove. In addition, the seeder is also specially designed with a series of linkage mechanisms. Components such as the first sprocket, the second sprocket and the chain can cooperate synchronously with the sowing action, and the drive wheel rotates accordingly, thereby realizing the movement of the entire machine. This not only ensures that the wheat seeds are accurately sown in different locations of the farmland, but also increases the planting density per unit area by shortening the row spacing, improves planting efficiency and productivity, and makes the seeder more practical.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] See also Figure 1 、 Figure 2 and Figure 4 In this embodiment, a wheat seeder for reducing the sowing amount and shortening the row spacing includes a frame 1, a sowing mechanism 2, a loosening mechanism 3 and a watering mechanism 4. The sowing mechanism 2 includes a seed bin 201 fixedly connected to the inner wall of the frame 1 and a rotating rod 203 rotatably sleeved on the inner wall of the seed bin 201, and a first servo motor 202 fixedly connected to the outer surface of the seed bin 201. By setting the seed bin 201, wheat seeds can be stored to facilitate subsequent sowing work. The output shaft end of the first servo motor 202 is fixedly connected to one end of the rotating rod 203. When the first servo motor 202 is started, the rotating rod 203 can be driven to rotate. The outer surface of the rotating rod 203 is fixedly connected to a plurality of seed disks 204. When the rotating rod 203 rotates, the plurality of seed disks 204 can be driven to rotate.

[0032] See also Figure 2 、 Figure 3 and Figure 4 , the outer surface of each seed tray 204 is provided with uniformly distributed seed grooves 205, and the inner wall of the seed bin 201 is fixedly connected with two scrapers 206. By setting the scrapers 206, the excess seeds can be scraped off during the rotation of the seed tray 204, leaving only one seed in the seed groove 205. The bottom end of the seed bin 201 is equipped with uniformly distributed sowing tubes 207. The number of sowing tubes 207 corresponds to the number of seed trays 204, and the position of each sowing tube 207 is located directly below the seed tray 204. By limiting the distance between the sowing tubes 207 and the seed tray 204, the seed tray 204 can be easily moved. The relationship between them can enable the seeds in the seed slot 205 to be transported to the farmland through the sowing tube 207 for sowing. The size of the seed slot 205 can only accommodate one wheat seed. When the seed tray 204 rotates one circle, a certain amount of seeds can be sown into the farmland through the sowing tube 207. The sowing amount achieved by the seed tray 204 rotating one circle is related to the number of seed slots 205 opened on the seed tray 204. A certain amount of seed slots 205 can be opened on the seed tray 204 as needed, thereby achieving more accurate sowing and avoiding seed waste.

[0033] It should be noted that when the first servo motor 202 drives the rotating rod 203 to rotate, the speed is slow, which can ensure that the seeds in the seed groove 205 can smoothly fall into the sowing tube 207 and be sown into the soil through the sowing tube 207.

[0034] See also Figure 1 、 Figure 2 and Figure 3 The other end of the rotating rod 203 is fixedly connected to the first sprocket 208, and the tail end of the frame 1 is rotatably connected to the driving shaft 209. The outer surface of the driving shaft 209 is fixedly connected to the second sprocket 210. The outer surface of the second sprocket 210 is provided with a chain 211. The first sprocket 208 is connected to the driving shaft 209 through the chain 211. The outer surface of the driving shaft 209 is fixedly connected to four driving wheels 212. When the first servo motor 202 is started, the second sprocket 210 and the driving shaft 209 can be driven to rotate by the first sprocket 208 and the chain 211 at one end of the rotating rod 203. When the moving shaft 209 rotates, the driving wheel 212 can be used to move the device, so that the work of sowing while moving can be achieved, resources can be used reasonably, and the sowing process can be optimized at the same time. The diameter value of the first sprocket 208 is slightly larger than the diameter value of the second sprocket 210, and a reserved groove adapted to the chain 211 is provided on the surface of the frame 1. By limiting the size relationship between the first sprocket 208 and the second sprocket 210, the rotation speed of the second sprocket 210 can be made slightly larger than the rotation speed of the first sprocket 208, so that the effect of shortening the sowing row spacing can be achieved.

[0035] It should be noted that the rotational speed of the rotating rod 203 and the rotational speed of the drive shaft 209 can be adjusted by the size of the first sprocket 208 and the second sprocket 210, and the size of the drive wheel 212 can also be adjusted. This ensures that the device can move an appropriate distance after the seed disc 204 rotates one circle to sow a certain amount of seeds, thereby effectively shortening the sowing row spacing and achieving higher quality sowing work.

[0036] See also Figure 1 、 Figure 2 and Figure 3 The loosening mechanism 3 includes a loosening knife assembly 301 installed at the front end of the frame 1, and a second servo motor 302 is fixedly connected to one side of the frame 1. The output shaft end of the second servo motor 302 is fixedly connected to the rotating shaft end of the loosening knife assembly 301. By setting the loosening mechanism 3, the soil in the farmland can be loosened, which is convenient for subsequent wheat sowing work. Two symmetrical steering wheels 5 are installed at the front end of the frame 1, and the loosening knife assembly 301 is located between the two steering wheels 5. By setting the steering wheel 5, the device can have a steering function, which is convenient for wheat sowing work at various positions in the farmland and is more practical. The irrigation mechanism 4 includes a water tank 401 fixedly connected to the upper surface of the frame 1, and the bottom end of the water tank 401 is connected to the upper surface of the frame 1. The pump is connected to a nozzle 402, and a liquid injection port 403 is installed at the top of the water tank 401. By setting up the irrigation mechanism 4, the farmland where wheat seeds have been sown can be properly watered, thereby optimizing the actual use effect of the device. A rotatable soil-pressing roller 6 is installed on the bottom surface of the frame 1, and the soil-pressing roller 6 is located between the driving wheel 212 and the nozzle 402. By setting up the soil-pressing roller 6, the land where wheat sowing is completed can be flattened, thereby optimizing the wheat sowing process. A bulldozer block 7 is fixedly connected to the bottom surface of the frame 1, and the bulldozer block 7 is located between the sowing pipe 207 and the loosening knife assembly 301. By setting up the bulldozer block 7, the soil turned over by the loosening knife assembly 301 can be flattened, thereby facilitating the sowing of wheat seeds into the farmland through the sowing pipe 207.

[0037] In this embodiment, a wheat seeder that reduces the sowing amount and shortens the row spacing is provided. By starting the first servo motor 202, the rotating rod 203 can drive several seed discs 204 to rotate, and the seeds in the seed bin 201 will fall into the seed groove 205 on the surface of the seed disc 204 due to their own gravity. The size of the seed groove 205 can only accommodate one wheat seed. In this way, one rotation of the seed disc 204 can achieve the work of sowing a fixed amount of wheat seeds. At the same time, the first sprocket 208, the second sprocket 210 and the chain 211 are provided, and the driving wheel 212 can be rotated during the sowing process, thereby realizing the movement of the device, so that the wheat seeds can be accurately sown in different positions of the farmland. At the same time, the sowing row spacing is shorter, which can increase the planting density per unit area and is more practical.
