Description

Technical Field

[0001] This utility model relates to the technical field of wheat planting, and in particular to a soil covering and compaction device for a wheat planter. Background Technology

[0002] In most major grain-producing areas of my country, wheat is grown, and mechanical sowing is commonly used. After sowing, a compaction mechanism is usually used to compact the soil, ensuring that the wheat seeds make full contact with the soil and guaranteeing germination quality. Existing technology announcement number CN105638033A discloses a dual-purpose furrow-sowing and flat-sowing soil-covering, leveling, and compacting device, including: a spiral soil-covering and leveling device, a compaction device, a floating arm, a limiting block, side plates, and a transmission device. The compaction device is mounted on both side plates, with a thin-walled bearing installed on the shaft head. The floating arm is mounted on a thin-walled bearing seat. The shaft head of the spiral soil-covering and leveling device passes through an arc-shaped notch in the side plate and is installed in the thin-walled bearing on the floating arm. The limiting block is installed on the side plate, with its upper part contacting the lower part of the floating arm. The transmission device is installed on the shaft head inside the floating arm. The side plates have mounting holes at the front and rear, allowing the entire device to be mounted on the side plate of a wheat seeder frame in either the forward or reverse direction via these holes, enabling furrow or flat sowing. However, the press roller is prone to slipping on wet or uneven surfaces. During the pressing process, mud will constantly stick to the press roller, increasing the rotational resistance of the press roller and affecting the leveling effect. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a soil covering and compaction device for wheat planters that can adapt to changes in terrain, operate at high working speeds, scrape away soil in real time, achieve good compaction effect, and improve work efficiency.

[0004] This utility model discloses a soil covering and compaction device for a wheat seeder, comprising a crossbeam, a connecting component, a supporting component, a compaction component, and a cleaning component. The connecting component is installed on the left side of the crossbeam, and the supporting component is installed on the right side. The compaction component is mounted on the supporting component, and the cleaning component is installed on the compaction component. The crossbeam is connected to the seeder frame via the connecting component. The supporting component pushes the compaction component to compact the soil, ensuring close contact between the seeds and the soil and guaranteeing seedling emergence. The supporting component can swing and float up and down to adapt to changes in terrain, enabling operation at higher speeds. It provides excellent compaction, improves working conditions, and increases work efficiency. The cleaning component cleans the compaction component, scraping away soil in real time to reduce rotational resistance.

[0005] Preferably, the connecting components include two connecting columns, two connecting frames, and two connecting pins. The two connecting columns are installed at the front and rear ends of the left side wall of the crossbeam. The connecting frames are installed on the connecting columns, and the connecting frames have connecting holes. The connecting pins are inserted into the connecting holes. During installation, the connecting frames are connected to the seeder frame, and then the connecting pins are inserted into the connecting holes and the fixing holes of the seeder frame to fix the connecting frames and the seeder frame, ensuring stability during use.

[0006] Preferably, the support components include two side beams, two fixing plates, and two sets of U-bolts. The fixing plates are connected to one end of the side beams and are installed at the front and rear ends of the crossbeams by U-bolts. When the seeder is in use, the frame drives the crossbeams to move downwards, and the crossbeams drive the fixing plates to push the compaction components to compact the soil. The fixing plates are connected to the crossbeams by U-bolts, which facilitates disassembly and maintenance and improves practicality.

[0007] Preferably, the compaction component includes two mounting plates, two connecting plates, two sets of T-shaped rods, two sets of mounting blocks, and two sets of compaction rollers. The two mounting plates are located between two side beams. Connecting plates are installed at the front and rear ends of the mounting plates. The connecting plates are connected to the side beams by bolts. T-shaped rods are slidably installed on the mounting plates. The T-shaped rods on the two mounting plates are alternately arranged. Mounting blocks are installed at the bottom of the T-shaped rods. Compaction rollers are rotatably installed on the front and rear sides of the mounting blocks. The side beams push the mounting plates so that the T-shaped rods drive the compaction rollers to contact the soil through the mounting blocks, thereby compacting the surface soil layer, improving the seed germination environment, and ensuring the compaction area of ​​the ground and the effectiveness of use.

[0008] Preferably, the device further includes multiple first springs, multiple push rings, and multiple second springs. The first springs are fitted onto the upper part of the T-shaped rod, with the top of the first spring connected to the top of the T-shaped rod and the bottom of the first spring connected to the top of the mounting plate. A push ring is installed at the lower part of the T-shaped rod. The second springs are fitted onto the lower part of the T-shaped rod, with the bottom of the second spring connected to the top of the push ring and the top of the second spring connected to the bottom of the mounting plate. Under normal conditions, the first springs maintain tension on the T-shaped rod, while the push rings ensure thrust on the T-shaped rod. When the ground is uneven, the pressing roller moves upward, pushing the T-shaped rod through the mounting block. The T-shaped rod drives the push ring to compress the second springs, simultaneously pulling the first springs, allowing the T-shaped rod to swing and float up and down, adapting to changes in terrain. This enables operation at higher speeds, provides good pressing effect, and improves working conditions.

[0009] Preferably, the cleaning component includes multiple sets of scrapers. Scrapers are symmetrically installed at the bottom of the push ring, with the scrapers located above the pressing roller. The lower part of the scrapers is set to a shape that matches the pressing roller. When the pressing roller rotates, the scrapers scrape off the mud adhering to the outer wall of the pressing roller in real time, reducing rotational resistance.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the crossbeam is connected to the seeder frame through the connecting component, and the supporting component pushes the compacting component to compact the soil, so that the seeds are tightly combined with the soil and the seedlings are guaranteed to emerge. The supporting component can swing and float up and down to adapt to changes in terrain, and can operate at a high working speed. The compaction effect is good, which helps to improve working conditions and increase work efficiency. The cleaning component can clean the compacting component and scrape off the soil in real time, reducing rotational resistance. Attached Figure Description

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] like Figures 1 to 5As shown, two connecting columns 2 are installed at the front and rear ends of the left side wall of the crossbeam 1. Connecting brackets 3 are installed on the connecting columns 2, and connecting holes are opened on the connecting brackets 3. Connecting pins 4 are inserted into the connecting holes. One end of the side beam 5 is connected to a fixing plate 6, which is installed at the front and rear ends of the crossbeam 1 by U-bolts 7. Two mounting plates 8 are located between the two side beams 5. Connecting plates 9 are installed at the front and rear ends of the mounting plates 8, and the connecting plates 9 are connected to the side beams 5 by bolts. T-shaped rods 10 are slidably installed on the mounting plates 8, and the T-shaped rods 10 on the two mounting plates 8 are alternately arranged. Mounting blocks 11 are installed at the bottom of the T-shaped rods 10. Pressing rollers 12 are rotatably mounted on the front and rear sides of block 11. A first spring 13 is fitted on the upper part of T-shaped rod 10. The top of the first spring 13 is connected to the top of T-shaped rod 10, and the bottom of the first spring 13 is connected to the top of mounting plate 8. A push ring 14 is installed on the lower part of T-shaped rod 10. A second spring 15 is fitted on the lower part of T-shaped rod 10. The bottom of the second spring 15 is connected to the top of push ring 14, and the top of push ring 15 is connected to the bottom of mounting plate 8. Scrapers 16 are symmetrically installed on the bottom of push ring 14. The scrapers 16 are located above pressing rollers 12, and the lower part of scrapers 16 is set to a shape that matches pressing rollers 12.

[0019] During installation, connect the connecting frame 3 to the seeder frame, then insert the connecting pin 4 into the connecting hole and the fixing hole of the seeder frame to fix the connecting frame 3 and the seeder frame, ensuring stability during use. When the seeder is in use, the frame drives the crossbeam 1 to move downwards, and the crossbeam 1 drives the fixing plate 6 to push the compaction component to compact the soil. The fixing plate 6 is connected to the crossbeam 1 by U-bolts 7, which facilitates disassembly and maintenance and improves practicality. The side beam 5 pushes the mounting plate 8 so that the T-shaped rod 10 drives the compaction roller 12 to contact the soil through the mounting block 11, thereby compacting the surface soil layer and improving the seed germination environment. The alternating compaction rollers 12 can ensure compaction of the ground. To ensure effective use, the first spring 13 maintains tension on the T-shaped rod 10 under normal conditions, while the push ring 14 ensures thrust on the T-shaped rod 10. When the ground is uneven, the pressing roller 12 moves upward and pushes the T-shaped rod 10 through the mounting block 11. The T-shaped rod 10 drives the push ring 14 to compress the second spring 15, while simultaneously pulling the first spring 13, allowing the T-shaped rod 10 to swing and float up and down to adapt to changes in terrain. It can operate at higher working speeds, has a good pressing effect, and helps improve working conditions. When the pressing roller 12 rotates, the scraper 16 scrapes away the dirt adhering to the outer wall of the pressing roller 12 in real time, reducing rotational resistance.

[0020] like Figures 1 to 5As shown, this utility model discloses a soil covering and compaction device for a wheat seeder. During operation, the connecting frame 3 is connected to the seeder frame, and the connecting pin 4 is inserted into the connecting hole and the fixing hole of the seeder frame to fix the connecting frame 3 and the seeder frame. When the seeder is in use, the frame drives the crossbeam 1 downwards. The crossbeam 1 drives the fixing plate 6 to push the side beam 5 and the mounting plate 8, causing the T-shaped rod 10 to drive the compaction roller 12 to contact the soil through the mounting block 11, thus compacting the surface soil layer and improving the seed germination environment. The alternately arranged compaction rollers 12 ensure a compaction area on the ground. When the ground is uneven, the compaction roller 12 moves upwards, pushing the T-shaped rod 10 through the mounting block 11. The T-shaped rod 10 drives the push ring 14 to compress the second spring 15, while simultaneously pulling the first spring 13, allowing the T-shaped rod 10 to swing and float up and down, adapting to changes in terrain and enabling operation at higher speeds. When the compaction roller 12 rotates, the scraper 16 scrapes away the soil adhering to the outer wall of the compaction roller 12 in real time, reducing rotational resistance.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
