[0002] Rice is an annual aquatic herb of the Poaceae family. It is an important grain widely cultivated in tropical Asia, with southern China being the main rice-producing area, and it is also grown in northern provinces. It is mainly divided into two subspecies: indica rice and japonica rice. There are many cultivated varieties under the subspecies. The mature caryopsis is used as medicine. It has a sweet and mild taste, aids digestion, and strengthens the spleen and stomach.

[0003] In the process of rice breeding, the traditional manual sowing method is not only inefficient, but also highly dependent on manpower, resulting in high labor intensity and easy errors. Although the existing automatic sowing devices on the market have improved sowing efficiency to some extent, they are usually expensive, complex in structure, and difficult to maintain. This is not only difficult for poor families with limited economic conditions to afford, but also relatively complicated to operate. Therefore, it is particularly important to develop a rice breeding auxiliary device that is simple in structure, easy to operate, and cost-effective. Utility Model Content

[0004] One objective of this invention is to provide a rice breeding sowing aid device. This invention addresses the problem mentioned in the background that traditional manual sowing methods in rice breeding are not only inefficient but also highly dependent on human labor, resulting in high labor intensity and a high risk of errors. Although existing automatic sowing devices on the market have improved sowing efficiency to some extent, they are usually expensive, complex in structure, and difficult to maintain. This makes them not only unaffordable for impoverished families with limited economic resources but also relatively complicated to operate.

[0005] A rice breeding aid device according to an embodiment of the present invention includes:

[0006] The mobile mechanism includes a vehicle body, with movable wheels rotatably mounted on the underside of the vehicle body via a drive shaft, and a support platform connected to the top of the vehicle body via an electric push rod for adjusting the sowing depth;

[0007] The sowing mechanism includes a hopper connected to the top of a support platform via a fixed component. Inside the hopper, a cleaning cylinder and a conveying cylinder are rotatably arranged. At one end of the cleaning cylinder and the conveying cylinder, a flexible brush and a metering groove are respectively provided. The flexible brush is used to clean the inside of the metering groove. The conveying cylinder and the cleaning cylinder are linked by a second transmission component, which is driven by a first transmission component. At the bottom of the hopper, a retractable sowing component is used to sow rice seeds into the soil.

[0008] Preferably, four electric push rods are symmetrically arranged and located at the four corners between the vehicle body and the support platform.

[0009] Preferably, the fixing component is a bolt.

[0010] Preferably, the flexible brush and the metering groove are both arranged in a circular pattern and there are several of them.

[0011] Preferably, a guide plate is fixedly installed at the upper end of the inside of the hopper, and the guide plate corresponds to the metering groove opened on the surface of the conveying cylinder.

[0012] Preferably, the second transmission assembly consists of four meshing gears, wherein two gears are fixed to the ends of the conveying cylinder and the cleaning cylinder, respectively.

[0013] Preferably, the first transmission assembly consists of a transmission wheel and a transmission belt. The transmission wheel is distributed on the outside of the drive shaft, above the vehicle body, and on one side of the gear. The transmission belt above the vehicle body is mounted on the vehicle body through a bearing seat.

[0014] Preferably, the retractable seeding assembly includes a sleeve and a cam fixed to the other end of the conveying cylinder. The sleeve is movably configured via a groove opened on the surface of the hopper. The cam and the sleeve are connected by a connecting rod to achieve lifting and lowering movement. A conical seeding plate is rotatably configured at the bottom of the sleeve via a first rotating seat. A second rotating seat is fixedly configured on the outer side of the hopper. A third rotating seat is movably configured at one end of the conical seeding plate corresponding to the second rotating seat. A crank is rotatably configured between the second rotating seat and the third rotating seat.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problems of low efficiency and error-proneness in traditional manual sowing through its specially designed sowing mechanism. In use, seeds first enter the hopper and are guided by a guide plate to a metering groove on the surface of the conveyor cylinder. As the vehicle's wheels roll, the conveyor cylinder, cleaning cylinder, and drive shaft are connected via a first and second transmission assembly, synchronously driving the various components of the sowing mechanism as the vehicle moves. Simultaneously, the seeds, under the undulation of the flexible brush, enter the area below the hopper. At the same time, the conveyor cylinder drives the cam to rotate, causing the sleeve, guided by the connecting rod and the sliding groove, to move towards the soil. The moving inserts the seeder while the conical seeding plate connected to the bottom of the sleeve rotates and, with the help of the curved rod, opens up the soil and sows the seeds into the soil. When the cam rises to the highest point, the sleeve rises back to the top, and the third rotating seat connected to the bottom of the curved rod slides to the bottom of the arc-shaped seeding plate. At this time, the two arc-shaped seeding plates close, which can collect the fallen seeds again. By repeating the above steps, the problem of low efficiency and easy error in traditional manual sowing is effectively solved, the accuracy and efficiency of sowing are improved, and the difficulty of operation is reduced, making it suitable for poor families with limited economic conditions.

[0017] This utility model, through its movable mechanism, allows the device to move flexibly in the field by utilizing the cooperation between the vehicle body, drive shaft, and moving wheels. The electric push rods are symmetrically arranged between the vehicle body and the support platform. By adjusting the extension and retraction of the push rods, the height of the support platform can be adjusted, thereby controlling the sowing depth. This improves sowing efficiency and makes the rice breeding process easier and more efficient. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A rice breeding aid device, comprising:

[0026] The mobile mechanism 1 includes a vehicle body 101, with a moving wheel 103 rotatably mounted below the vehicle body 101 via a drive shaft 102, and a support platform 106 connected to the top of the vehicle body 101 via an electric push rod 105 for adjusting the sowing depth. The electric push rod is symmetrically arranged between the vehicle body and the support platform. By adjusting the extension and retraction of the push rod, the height of the support platform can be adjusted, thereby controlling the sowing depth and thus improving the sowing efficiency.

[0027] The sowing mechanism 2 includes a feeding hopper 201 connected to the top of the support platform 106 via a fixing component. Inside the feeding hopper 201, a cleaning cylinder 202 and a conveying cylinder 203 are rotatably mounted. A flexible brush 205 and a metering groove 204 are respectively provided at one end of the cleaning cylinder 202 and the conveying cylinder 203, used to clean the interior of the metering groove 204 with the flexible brush 205. The conveying cylinder 203 and the cleaning cylinder 202 are linked by a second transmission component 217, which is driven by a first transmission component 216. The bottom of the feeding hopper 201 is equipped with a retractable seeding assembly to sow rice seeds into the soil. The retractable seeding assembly includes a sleeve 208 and a cam 209 fixed to the other end of the conveying cylinder 203. The sleeve 208 is movably positioned via a groove 207 on the surface of the feeding hopper 201. The cam 209 and the sleeve 208 are connected by a connecting rod 210 for lifting and lowering. A conical seeding plate 211 is rotatably mounted on the bottom of the sleeve 208 via a first rotating seat 212. A second rotating seat 213 is fixedly mounted on the outer side of the feeding hopper 201. A third rotating seat 214 is movably disposed at one end of the seeding plate 211 corresponding to the second rotating seat 213. A crank rod 215 is rotatably disposed between the second rotating seat 213 and the third rotating seat 214. The seeds first enter the feeding hopper and are guided by the guide plate to the quantitative groove opened on the surface of the conveying cylinder. When the moving wheels of the vehicle body roll, the conveying cylinder, the cleaning cylinder, and the drive shaft are connected through the cooperation between the first transmission component and the second transmission component, so that the various components in the seeding mechanism are synchronously driven when the vehicle body moves. At this time, the seeds are fed into the seeding mechanism under the undulation of the flexible brush. The material enters the bottom of the hopper, while the conveying cylinder drives the cam to rotate circumferentially. This causes the sleeve to move towards the soil under the guidance of the connecting rod and the slide groove. At the same time, the conical seeding plate connected to the bottom of the sleeve, with the cooperation of the curved rod, opens up the soil and sows the seeds into the soil. When the cam rises to the highest position, the sleeve rises back to the top, and the third rotating seat connected to the bottom of the curved rod slides to the bottom of the arc-shaped seeding plate. At this time, the two arc-shaped seeding plates close, so that the falling seeds can be collected again, waiting for the reciprocating motion of the above steps.

[0028] Example 1: Four electric push rods 105 are symmetrically arranged at the four corners between the vehicle body 101 and the support platform 106. The electric push rods at the four corners can provide stability during operation and ensure stability during height adjustment. The fixing component is bolts. Several flexible brushes 205 and quantitative grooves 204 are arranged in a circle. A guide plate 206 is fixedly installed at the upper end of the inside of the hopper 201. The guide plate 206 corresponds to the quantitative grooves 204 opened on the surface of the conveying cylinder 203, which can evenly distribute the seeds inside the quantitative grooves, thereby improving the sowing effect.

[0029] Example 2: The second transmission assembly 217 consists of four meshing gears, two of which are fixed to the ends of the conveying cylinder 203 and the cleaning cylinder 202, respectively. The four gears enable relative movement between the conveying cylinder and the cleaning cylinder, which improves the cleaning of the quantitative groove by the flexible brush and avoids the problem of seed adhesion and blockage. The first transmission assembly 216 consists of a transmission wheel and a transmission belt. The transmission wheel is distributed on the outside of the drive shaft 102, above the vehicle body 101, and on one side of the gear. The transmission belt above the vehicle body 101 is mounted on the vehicle body 101 through a bearing seat. It can replace the operation of the motor-driven equipment. The sowing mechanism of the device can be operated simply by pushing the device to move in the soil, thereby reducing the cost.

[0030] Working principle: When the device is started, the electric push rods 105 (four symmetrically arranged) adjust the height of the support platform 106 to control the sowing depth and ensure sowing efficiency. The seeds enter the feed hopper 201 through the guide plate 206. The guide plate 206 ensures that the seeds are evenly distributed in the quantitative groove 204 on the surface of the conveying cylinder 203. The conveying cylinder 203 and the cleaning cylinder 202 are linked by the second transmission assembly 217 (composed of four gears). The gears are fixed to the ends of both to ensure relative movement between the conveying cylinder and the cleaning cylinder. The flexible brush 205 cleans the inside of the quantitative groove 204 to prevent blockage. When the vehicle body 101 moves, the drive shaft 102 drives the moving wheel 103 to roll, and at the same time, the first transmission assembly 216 (composed of four gears) drives the moving wheel 103 to roll. The first transmission assembly (comprising a wheel and a drive belt) transmits power to the second transmission component 217, enabling the sowing mechanism to operate. The conveyor cylinder 203 rotates, driving the cam 209, which in turn causes the sleeve 208 to move towards the soil under the guidance of the connecting rod 210 and the slide groove 207. The conical sowing plate 211, with the cooperation of the crank rod 215, opens up the soil and sows the seeds into it. When the cam 209 rises to its highest point, the sleeve 208 rises back, and the third rotating seat 214 slides to the bottom of the conical sowing plate 211. The two sowing plates close, collecting the fallen seeds and preparing for the next round of sowing. In this way, the device achieves automatic, efficient, and uniform sowing of rice seeds, while reducing the difficulty of operation and maintenance costs, making it suitable for users with different economic conditions.
