Description

Technical Field

[0001] This utility model relates to the technical field of agricultural seeding machinery, and in particular to an agricultural seeding and soil covering device. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. During the operation of a seeder, it is necessary to open furrows in the land before sowing to place the seeds. After the seeds are placed from the seeder into the furrows, the land after sowing needs to be covered with soil so that the seeds are buried in the soil.

[0003] In the prior art, the utility model patent with patent publication number CN213280622U discloses a furrowing and soil covering device for a seeder. This device can prevent the soil that has been plowed out from falling back into the furrow immediately after the furrowing plow passes through, which would cause the seeds to be buried too shallowly and affect sowing.

[0004] The furrowing and covering device for a seeder described in the above patent can sow crop seeds, but during the sowing and covering process, the covering roller is easily covered with mud due to soil moisture, which affects the covering effect of the covering roller. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an agricultural sowing and covering device that can prevent the covering roller from being covered with soil and avoid affecting the covering effect of the covering roller.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an agricultural sowing and soil-covering device, comprising a sowing and soil-covering mechanism and a cleaning mechanism. The sowing and soil-covering mechanism includes a sowing box, which is elongated and conical in shape. Multiple sets of sowing tubes are fixedly connected at equal intervals at the bottom of the sowing box. Each set of sowing tubes has a furrowing plow blade fixedly connected to its bottom. Each set of sowing tubes is equipped with a sowing valve. A traction frame is fixedly connected to the upper left side of the sowing box. L-shaped support plates are fixedly connected to the front and rear sides of the right side of the sowing box. Soil-covering rollers are rotatably mounted on the lower part of the two sets of L-shaped support plates. The cleaning mechanism includes a motor, which is fixedly installed on the right side of the sowing box. On the front L-shaped support plate, a reciprocating screw is fixedly connected to the motor output end, and the reciprocating screw is rotatably mounted on two sets of L-shaped support plates. A guide rod is fixedly connected between the two sets of L-shaped support plates, and the guide rod is located directly above the reciprocating screw. A slider is provided on the reciprocating screw, and the slider has a sliding hole. The slider slides onto the guide rod through the sliding hole. An arc-shaped scraper is integrally connected to the bottom end of the slider. The inner wall of the arc-shaped scraper contacts the outer wall of the covering roller. A driving synchronous pulley is fixedly connected to the rear end of the reciprocating screw, and a driven synchronous pulley is fixedly connected to the rear end of the covering roller. A synchronous belt is fitted on the driving synchronous pulley and the driven synchronous pulley.

[0008] Preferably, the top of the seeding box is fitted with a lid via a hinge, and two sets of latches are provided between the right end of the lid and the right end of the seeding box.

[0009] Preferably, the top of the box cover has an observation opening, and an observation window is fixedly installed inside the observation opening.

[0010] Preferably, a handle is fixedly connected to the right end of the box cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, when sowing and covering with soil, crop seeds are placed in the sowing box, furrows are opened by the furrowing plow, and the sowing valve is opened so that the crop seeds fall into the opened furrows through the sowing tube. Soil is then covered by the covering roller. When the motor is started, the motor drives the reciprocating screw to rotate, which in turn drives the slider to move back and forth along the guide rod. This causes the slider to drive the arc-shaped scraper to move back and forth. The reciprocating screw drives the covering roller to rotate through the transmission of the active synchronous pulley, the driven synchronous pulley, and the synchronous belt. During the covering process, the arc-shaped scraper continuously scrapes the surface of the covering roller, removing the soil adhering to the surface of the covering roller. This prevents the covering roller from being covered with soil and avoids affecting the covering effect. Attached Figure Description

[0018] Example

[0019] Please see Figures 1-4 This utility model discloses an agricultural sowing and soil covering device, comprising a sowing box 1 and a motor 8. The sowing box 1 is elongated and conical in shape. Multiple sets of sowing tubes 2 are fixedly connected at equal intervals at the bottom of the sowing box 1. Each set of sowing tubes 2 has a furrowing plow blade 3 fixedly connected to its bottom. Each set of sowing tubes 2 is equipped with a sowing valve 4. A traction frame 5 is fixedly connected to the upper left side of the sowing box 1. L-shaped support plates 6 are fixedly connected to the front and rear sides of the right side of the sowing box 1. Soil covering rollers 7 are rotatably mounted on the lower part of the two sets of L-shaped support plates 6. The motor 8 is fixedly mounted on the sowing box. On the L-shaped support plate 6 at the front right end of box 1, a reciprocating screw 9 is fixedly connected to the output end of motor 8. The reciprocating screw 9 is rotatably mounted on two sets of L-shaped support plates 6. A guide rod 10 is fixedly connected between the two sets of L-shaped support plates 6. The guide rod 10 is located directly above the reciprocating screw 9. A slider 11 is fitted on the reciprocating screw 9. The slider 11 has a sliding hole. The slider 11 is slidably fitted onto the guide rod 10 through the sliding hole. An arc-shaped scraper 12 is integrally connected to the bottom end of the slider 11. The inner wall of the arc-shaped scraper 12 is flush with the outer wall of the covering roller 7. The reciprocating screw 9 is fixedly connected to the rear end of a drive synchronous pulley 13, and the soil covering roller 7 is fixedly connected to the rear end of a driven synchronous pulley 14. A synchronous belt 15 is fitted onto both the drive and driven synchronous pulleys 13 and 14. In use, during sowing and soil covering, crop seeds are placed in the sowing box 1, furrows are opened using the furrowing plow 3, and the sowing valve 4 opens the sowing tube 2 to allow the seeds to fall into the furrows. The soil covering roller 7 then covers the seeds. The motor 8 is started, driving the reciprocating screw 9. The rotation causes the reciprocating screw 9 to drive the slider 11 to move back and forth along the guide rod 10, which in turn causes the slider 11 to drive the arc-shaped scraper 12 to move back and forth. The reciprocating screw 9 drives the covering roller 7 to rotate through the drive synchronous pulley 13, the driven synchronous pulley 14 and the synchronous belt 15. When the covering roller 7 is covering soil, the arc-shaped scraper 12 continuously scrapes the surface of the covering roller 7 to remove the soil stuck to the surface of the covering roller 7, thereby preventing the covering roller from being covered with soil and avoiding affecting the covering effect of the covering roller.

[0020] The top of the seeding box 1 is fitted with a lid 16 via a hinge, and two sets of latches 17 are provided between the right end of the lid 16 and the right end of the seeding box 1. After a sufficient amount of crop seeds are put into the seeding box 1, the lid 16 can be placed on the seeding box 1 by means of the latches 17, so as to prevent foreign objects from entering the seeding box 1.

[0021] The top of the box cover 16 has an observation opening, and an observation window 18 is fixedly installed inside the observation opening; by setting the observation window 18, it is easy to observe the amount of seeds remaining in the seed box 1 so that they can be replenished in time.

[0022] A handle 19 is fixedly connected to the right end of the box cover 16; by setting the handle 19, the box cover 16 can be opened and closed more conveniently.

[0023] This utility model discloses an agricultural sowing and soil covering device. In operation, the traction frame 5 is connected to an external traction machine, such as a tractor cab, via a pin. The cover 16 is opened using the latch 17, and seeds are poured into the sowing box 1, spreading them evenly inside. During sowing and soil covering, the device is moved by the traction machine. Simultaneously, the sowing valve 4 is opened and the motor 8 is started. During traction, furrows are opened using the furrowing plow blade 3. The opening of the sowing valve 4 allows crop seeds to fall into the furrows through the sowing tube 2. Soil is then covered by the soil covering roller 7. Starting the motor 8 drives the reciprocating screw 9, which in turn drives the slider 11. The guide rod 10 moves back and forth, causing the slider 11 to drive the arc-shaped scraper 12 to move back and forth. The reciprocating screw 9 drives the covering roller 7 to rotate through the drive synchronous pulley 13, driven synchronous pulley 14 and synchronous belt 15. When covering the soil, the arc-shaped scraper 12 continuously scrapes the surface of the covering roller 7 to remove the soil adhering to the surface of the covering roller 7, preventing the covering roller 7 from being covered with soil and avoiding affecting the covering effect of the covering roller 7. It should be noted that the slider 11 set on the reciprocating screw 9 is connected to the reciprocating screw 9 in a common way in the prior art. Mechanical technicians are also familiar with this connection method, so it will not be described in detail here.
