Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to an agricultural planting drilling device. Background Technology

[0002] In modern agricultural planting systems, precise and efficient planting operations are key prerequisites for ensuring crop yield and quality. With the continuous advancement of agricultural modernization, various planting technologies and equipment are constantly iterating and upgrading, injecting strong momentum into improving agricultural production efficiency. However, among many planting processes, the drilling operation, as an important pre-process of sowing, transplanting, and fertilization, has long faced severe challenges in terms of its operational effectiveness and stability. The shortcomings of existing technologies have gradually become bottlenecks restricting the development of precision agricultural planting, and innovation breakthroughs are urgently needed.

[0003] In traditional agricultural planting practices, drilling operations mainly rely on manual hand tools or simple machinery. Manual drilling is not only extremely labor-intensive, requiring workers to bend over for long periods of time, but also extremely inefficient in large-scale planting scenarios, making it difficult to meet the needs of large-scale planting. Even when some simple drilling machinery is introduced, these devices can mostly only perform basic drilling functions and lack specific guarantees for the stability of the holes.

[0004] In farmland environments with complex and variable soil conditions, especially for sandy soils with low clay content and loose texture, and for plots with high soil moisture content and soft structure after rain, the holes are prone to collapse after traditional drilling operations. This drawback directly leads to uneven sowing depth, difficulty in spreading the roots of transplanted seedlings, and even prevents seeds from falling accurately to the predetermined depth, seriously affecting the germination rate and uniformity of crop growth. To compensate for this defect, growers often need to invest a lot of extra manpower to repair the collapsed holes, which not only significantly increases planting costs but also delays the best planting time and disrupts the rhythm of agricultural production.

[0005] The collapse of holes can cause seeds or seedlings to deviate from the preset planting depth. Seeds cannot obtain sufficient soil coverage and a stable growth environment, and seedling roots cannot take root and stabilize in the collapsed holes, which can easily lead to lodging, slow growth and other problems. This seriously affects the survival rate and growth consistency of crops, and ultimately leads to a decline in both the yield and quality of crops. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides an agricultural planting drilling device to solve the problem of automatically reinforcing the holes after drilling and preventing the holes from collapsing.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An agricultural planting hole-drilling device, comprising: The base has a side plate installed on one side of the top of the base. A drive shaft is rotatably connected to the outer wall of the side plate. A perforated eccentric wheel and a cleaning eccentric wheel are respectively installed on the outer wall of the drive shaft from front to back. The adjustment assembly includes a slide groove and an adjustment block. The slide groove is located on the outer wall of the base, and the adjustment block is slidably connected inside the slide groove. A connecting shaft is slidably connected up and down inside the adjustment block, and the connecting shaft abuts against the outer wall of the perforated eccentric wheel. The drilling component includes a drilling cylinder, a hole-expanding shaft, a sliding shaft, and a hole-expanding arc plate. The drilling cylinder is installed at the lower part of the connecting shaft. The hole-expanding arc plate slides on the outer wall of the drilling cylinder. The hole-expanding shaft is located inside the drilling cylinder and is used to control the extension of the hole-expanding arc plate. The sliding shaft is located at the bottom of the sliding shaft and is used to break the soil and cooperate with the hole-expanding shaft to control the retraction of the hole-expanding arc plate. Through the setting of the drilling component and the adjustment component, this device can automatically drill holes when pushed. The drilling component can drill multiple holes continuously. Different spacing can be used for different crops. After drilling, in order to prevent the holes from collapsing, the device can automatically expand and reinforce the holes during drilling to prevent uneven sowing depth or difficulty in spreading the roots of transplanted seedlings caused by hole collapse, without the need for manual secondary adjustment.

[0008] Preferably, a drive motor is fixedly installed on the side wall of the side plate, and the output end of the drive motor is fixedly connected to one end of the drive shaft; The lower end of the reset spring is fixedly mounted on the adjusting block, and the upper end of the reset spring is fixedly mounted on the outer wall of the connecting shaft. The pressing plate is located on the upper part of the base, and the pressing plate is driven by the perforated eccentric wheel.

[0009] Preferably, a fixing frame is fixedly installed on the outer wall of the adjusting block; A shrinking cylinder is fixedly installed on the inner top wall of the punching cylinder. An expanding shaft is slidably connected inside the shrinking cylinder. A stretching plate is fixedly installed on the outer wall of the expanding shaft. The stretching plate abuts against the fixing frame and is slidably connected to the outer wall of the punching cylinder. A reaming plate is slidably connected to the outer wall of the reaming shaft. Friction textures are provided on the outer wall of the reaming plate to slow its sliding. The width of the reaming plate increases sequentially from top to bottom. The reaming plate matches the connecting block and is slidably connected to the inner wall of the reaming shaft. The outer wall of the reaming plate abuts against one end of the reaming arc plate located inside the drilling cylinder. A resisting spring is fixedly installed on the side wall of the connecting block, and the other end of the resisting spring is fixedly connected to the inner wall of the drilling cylinder. In use, the device first starts by activating the drive motor, causing the drive shaft to rotate. This displacement is achieved by pushing the base. The rotation of the device drives the eccentric drilling wheel to rotate, and the eccentric drilling wheel reciprocates against the pressing plate. The pressing plate drives the connecting shaft to move downward, and the return spring reciprocates to compress and reset. The descent of the connecting shaft drives the drilling cylinder to move downward, so that the drilling cylinder can drill holes in the ground. Through the setting of the tension plate and the fixing frame, this device can automatically expand and reinforce the hole when the drilling cylinder is automatically drilling. The fixing frame can stretch the tension plate to achieve the function of automatic hole expansion, prevent the hole from collapsing, and automatically reset after drilling, so as to facilitate drilling and hole expansion reinforcement again.

[0010] Preferably, a top groove is formed on the outer wall of the connecting block; The bottom of the punching cylinder is slidably connected to a sliding shaft. An upper spring is installed on the outer wall of the lower part of the sliding shaft. The bottom of the upper spring is fixedly connected to the inner wall of the punching cylinder. An abutting rod is fixedly installed on the outer wall of the upper part of the sliding shaft. The top of the abutting rod abuts against the bottom of the connecting block.

[0011] Preferably, the enlarging shaft is internally slidably connected to an inner shaft, the bottom of the inner shaft matches the top of the sliding shaft, a pressure spring is fixedly installed on the top of the inner shaft, and the other end of the pressure spring is fixedly connected to the inner top wall of the enlarging shaft. An expansion plate is fixedly installed on the outer wall of the inner shaft. The thickness of the expansion plate increases from bottom to top. The expansion plate abuts against the expansion shaft, which is installed at one end of the expansion plate. In the initial state, the sliding shaft of this device is temporarily fixed because the abutting rod abuts against the bottom of the connecting block. The connecting block limits the abutting rod and the sliding shaft. The abutting rod slides within the drilling cylinder, and any limiting sliding method in the prior art can be used. For example, a limiting groove is opened on the inner wall of the drilling cylinder, and a limiting block is installed on the outer wall of the abutting rod. The abutting rod slides into the limiting groove through the limiting block. Therefore, when the drilling cylinder moves downward to drill, The sliding shaft can break the soil. When the hole is enlarged and reinforced, as the drilling cylinder continues to descend, the tension plate will be stretched by the fixing frame. When the drilling cylinder descends, the fixing frame is stationary. When the tension plate is stretched, the enlarging shaft moves upward, and the enlarging plate on its outer wall moves upward accordingly. The abutment surface of the enlarging plate and the connecting block gradually increases, and the connecting block moves outward, causing the enlarging arc plate to extend outward. At this time, the drilling cylinder is in the state after being lowered and drilling. The enlarging arc plate enlarges and reinforces the hole. When the drilling cylinder returns to its original position, the abutment spring causes the enlarging arc plate to return to its original position. The outward displacement of the connecting block will cause the abutment rod to... Opposite to the abutment groove, the abutment rod is inserted into the interior of the abutment groove. At this time, the abutment rod disengages from the abutment at the bottom of the connecting block, and the sliding shaft disengages from the abutment, becoming slidable. As the drilling cylinder descends, the sliding shaft abuts against the inner bottom of the hole. Because the sliding shaft loses the abutment force of the abutment rod, it contracts inward when subjected to an upward abutment force, inserting into the interior of the expanding shaft. At this point, the inner shaft is displaced inward under force. Initially, the inner shaft, under the action of the compression spring, is in a resisted and extended state. The outer expansion plate on the outer wall of the inner shaft abuts against the outer expansion shaft, causing the expanding plate to extend outward, facilitating abutment against the expanding arc plate. Meanwhile, the sliding... When the axial displacement is upward, the hole is in the expanded state. The sliding shaft abuts against the inner shaft, causing the outer expanding plate to disengage from the outer expanding shaft. This allows the connecting block to slide inward under the action of the abutment spring, and the expanding arc plate is in a contracted state. Through the setting of the sliding shaft, the sliding shaft is in a relatively fixed state during normal drilling, breaking the ground to facilitate drilling. After drilling and expanding are completed, the sliding shaft moves inward, causing the expanding plate to contract and the expanding arc plate to reset. This avoids the soil being stretched when the expanding arc plate is extended when the drilling cylinder is pulled out of the hole, thus preventing the collapse of the inner wall of the hole due to the pulling out of the drilling cylinder.

[0012] Preferably, a seeding box is installed in the middle of the base and is located at the rear end of the punching cylinder. A seeding control block is slidably connected to the bottom of the seeding box, and the seeding control block is in communication with the interior of the seeding box. The seeding control block of this device can be any existing seeder that can perform the seeding function, which will not be elaborated further here. The seeding box enables automatic seeding after punching. The sliding adjustment of the seeding control block allows this device to perform seeding at different intervals for holes with different spacings, meeting diverse needs.

[0013] Preferably, the system includes a cover component, which comprises a drive shaft and a sweeping roller. The drive shaft is drivenly connected to the drive shaft, and the sweeping roller is slidably connected to the outer wall of the drive shaft. Preferably, a linkage shaft is rotatably connected to one end of the top of the base, and a drive bevel gear is fixedly installed on the outer wall of the linkage shaft. The drive bevel gear meshes with the driving bevel gear, and the driving bevel gear is installed on the outer wall of the drive shaft. The linkage shaft is driven to the drive shaft via a linkage belt.

[0014] Preferably, a cleaning spring is fixedly installed on the outer wall of the drive shaft, and the other end of the cleaning spring is fixedly connected to the bottom of the base; The device comprises two sweeping rollers, which are connected by a connecting frame via bearings. A descending shaft is fixedly installed on the outer wall of the connecting frame, and the top of the descending shaft matches the sweeping eccentric wheel. When the drive shaft rotates, the device will synchronously drive the transmission shaft to rotate via the linkage shaft, thereby causing the transmission shaft to drive the sweeping rollers to rotate. The sweeping rollers fill the soil on the outer wall of the hole into the hole, achieving an automatic covering function. At the same time, to avoid the sweeping rollers from spinning idly, the descending shaft of the device can drive the sweeping rollers to descend, so that they rotate in contact with the ground. During rotation, the sweeping rollers are located on the outer wall of the hole.

[0015] The beneficial effects of this invention are as follows: 1. This device, through the setting of the punching component and adjustment component, can automatically punch holes when pushed. The punching component can punch multiple holes continuously, and different spacing can be used for different crops. At the same time, in order to prevent the holes from collapsing after punching, this device can automatically enlarge and reinforce the holes during punching, so as to prevent uneven sowing depth or difficulty in the root system of transplanted seedlings from collapsing, without the need for manual secondary adjustment.

[0016] 2. Through the setting of the tension plate and the fixing frame, this device enables the automatic hole enlargement and reinforcement function when the punching cylinder is automatically punching. The fixing frame can stretch the tension plate to achieve the automatic hole enlargement function, prevent the hole from collapsing, and automatically reset after punching, so as to facilitate the punching and hole enlargement reinforcement process again.

[0017] 3. This device, through the setting of the sliding shaft, is in a relatively fixed state during normal drilling, breaking the ground to facilitate drilling. After drilling and reaming are completed, the sliding shaft moves inward, causing the reaming plate to contract and the reaming arc plate to reset. This avoids the soil being stretched when the reaming arc plate is extended when the drilling cylinder is pulled out of the hole, thus preventing the collapse of the inner wall of the hole due to the pulling out of the drilling cylinder.

[0018] 4. This device enables automatic sowing after drilling by means of a sowing box. The sliding adjustment of the sowing control block allows the device to sow at different intervals for holes with different spacing, meeting diverse needs.

[0019] 5. When the drive shaft of this device rotates, it will synchronously drive the transmission shaft to rotate through the linkage shaft, so that the transmission shaft drives the sweeping roller to rotate. The sweeping roller fills the soil on the outer wall of the hole into the hole, realizing the function of automatic covering. At the same time, in order to avoid the sweeping roller from spinning idly, the lowering shaft of this device can drive the sweeping roller to descend, so that it rotates in contact with the ground. When rotating, the sweeping roller is located on the outer wall of the hole. Attached Figure Description

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] An agricultural planting drilling device, as shown in the attached document. Figure 1-8 As shown, it includes: A base 1 has a side plate 2 installed on one side of the top of the base 1. A drive shaft 3 is rotatably connected to the outer wall of the side plate 2. A perforated eccentric wheel 4 and a cleaning eccentric wheel 5 are respectively installed on the outer wall of the drive shaft 3 from front to back. The adjustment assembly includes a slide 6 and an adjustment block 7. The slide 6 is located on the outer wall of the base 1. The adjustment block 7 is slidably connected to the inside of the slide 6. The inside of the adjustment block 7 is slidably connected to a connecting shaft 8. The connecting shaft 8 abuts against the outer wall of the perforated eccentric wheel 4. The drilling component includes a drilling cylinder 9, a hole-expanding shaft 902, a sliding shaft 907, and a hole-expanding arc plate 10. The drilling cylinder 9 is installed at the lower part of the connecting shaft 8. The hole-expanding arc plate 10 slides on the outer wall of the drilling cylinder 9. The hole-expanding shaft 902 is located inside the drilling cylinder 9 and is used to control the extension of the hole-expanding arc plate 10. The sliding shaft 907 is located at the bottom of the sliding shaft 907 and is used to break the soil and cooperate with the hole-expanding shaft 902 to control the retraction of the hole-expanding arc plate 10. Through the setting of the drilling component and the adjustment component, this device can automatically drill holes when pushed. The drilling component can drill multiple holes continuously. Different gaps can be drilled for different crops. At the same time, after the drilling is completed, in order to prevent the hole from collapsing, this device can automatically expand and reinforce the hole during drilling to prevent uneven sowing depth or difficulty in spreading the roots of transplanted seedlings caused by hole collapse, without the need for manual secondary adjustment.

[0024] As attached Figure 1-2 As shown, a drive motor 201 is fixedly installed on the side wall of the side plate 2, and the output end of the drive motor 201 is fixedly connected to one end of the drive shaft 3. The lower end of the reset spring 801 is fixedly installed on the adjusting block 7, and the upper end of the reset spring 801 is fixedly installed on the outer wall of the connecting shaft 8. The pressing plate 802 is located on the upper part of the base 1, and the pressing plate 802 drives the 1 through the perforated eccentric wheel 4.

[0025] As attached Figure 2-4 As shown, a fixing bracket 701 is fixedly installed on the outer wall of the adjusting block 7; A shrinking cylinder 901 is fixedly installed on the inner top wall of the punching cylinder 9. An expanding shaft 902 is slidably connected inside the shrinking cylinder 901. A stretching plate 903 is fixedly installed on the outer wall of the expanding shaft 902. The stretching plate 903 abuts against the fixing frame 701 and is slidably connected to the outer wall of the punching cylinder 9. A reaming plate 904 is slidably connected to the outer wall of the reaming shaft 902. Friction textures are provided on the outer wall of the reaming plate 904 to slow its sliding. The width of the reaming plate 904 increases sequentially from top to bottom. The reaming plate 904 matches the connecting block 905 and is slidably connected to the inner wall of the reaming shaft 902. The outer wall of the reaming plate 904 abuts against one end of the reaming arc plate 10 located inside the drilling cylinder 9. A resisting spring 906 is fixedly installed on the side wall of the connecting block 905, and the other end of the resisting spring 906 is fixedly connected to the inner wall of the drilling cylinder 9. In use, the device first starts by activating the drive motor 201, causing the drive motor 201 to rotate the drive shaft 3. This displacement of the base 1, caused by the rotation of the drive shaft 3, drives the drilling eccentric wheel 4 to rotate. The pressing plate 802 reciprocates and pushes against the ground, causing the connecting shaft 8 to move downwards. The connecting shaft 8 is a sliding connection that moves up and down. When the connecting shaft 8 slides downwards, the return spring 801 is compressed. The reciprocating motion of the connecting shaft 8 punches holes, causing the return spring 801 to reciprocate and reset. The descent of the connecting shaft 8 causes the punching cylinder 9 to move downwards, allowing the punching cylinder 9 to punch holes in the ground. Through the setting of the tension plate 903 and the fixing frame 701, this device can automatically expand and reinforce holes when the punching cylinder 9 is automatically punching. The fixing frame 701 can stretch the tension plate 903 to achieve the function of automatic hole expansion and reinforcement, thus realizing the function of automatic hole expansion and preventing hole collapse. After punching, it can automatically reset, which is convenient for punching and hole expansion reinforcement.

[0026] As attached Figure 3-5 As shown, a top groove 913 is provided on the outer wall of the connecting block 905; The bottom of the punching cylinder 9 is slidably connected to a sliding shaft 907. An upper spring 914 is installed on the outer wall of the lower part of the sliding shaft 907. The bottom of the upper spring 914 is fixedly connected to the inner wall of the punching cylinder 9. An abutting rod 908 is fixedly installed on the outer wall of the upper part of the sliding shaft 907. The top of the abutting rod 908 abuts against the bottom of the connecting block 905.

[0027] As attached Figure 3-5 As shown, an inner shaft 909 is slidably connected inside the expanding shaft 902. The bottom of the inner shaft 909 matches the top of the sliding shaft 907. A compression spring 910 is fixedly installed on the top of the inner shaft 909. The other end of the compression spring 910 is fixedly connected to the inner top wall of the expanding shaft 902. An outer expansion plate 911 is fixedly installed on the outer wall of the inner shaft 909. The thickness of the outer expansion plate 911 increases from bottom to top. The outer expansion plate 911 abuts against the outer expansion shaft 912, which is installed at one end of the expansion plate 904. In the initial state, the sliding shaft 907 of this device is temporarily fixed because the abutting rod 908 abuts against the bottom of the connecting block 905. The connecting block 905 limits the abutting rod 908 and the sliding shaft 907. The abutting rod 908 slides within the punching cylinder 9, and any limiting sliding method in the prior art can be used. For example, a limiting groove is opened on the inner wall of the punching cylinder 9, and a limiting block is installed on the outer wall of the abutting rod 908. The rod slides into the limiting groove through the limiting block. Therefore, in the punching cylinder... When the drilling cylinder 9 moves downwards to drill, the sliding shaft 907 can break the soil. When the hole is enlarged and reinforced, as the drilling cylinder 9 continues to descend, the tension plate 903 will be stretched by the fixing frame 701. When the drilling cylinder 9 descends, the fixing frame 701 is in a stationary state. When the tension plate 903 is stretched, the expanding shaft 902 moves upwards, and the expanding plate 904 on its outer wall moves upwards accordingly. The abutment surface of one end of the expanding plate 904 and the connecting block 905 gradually increases, and the connecting block 905 moves outwards, thereby causing the expanding arc plate 10 to extend outwards. At this time, the drilling cylinder 9 is in the state after being lowered to drill. The expanding arc plate 10 enlarges and reinforces the hole. When the drilling cylinder 9 returns to its original position, the expanding arc plate 10 is reset by the abutment spring 906. The outward displacement of the connecting block 905 will cause the abutment rod 908 to align with the abutment groove 913, and the abutment rod 908 will insert into the interior of the abutment groove 913. At this time, the abutment rod 908 will disengage from the bottom of the connecting block 905, and the sliding shaft 907 will disengage from the abutment, becoming slidable. As the drilling cylinder 9 descends, the sliding shaft 907 abuts against the bottom of the hole. Because the sliding shaft 907 loses the abutment force of the abutment rod 908, it will contract inward when subjected to an upward abutment force, inserting into the interior of the expanding shaft 902. At this time, the inner shaft 909 will be displaced inward under force, whereas initially, the inner shaft 909 was in a resisting extended state under the action of the compression spring 910. The outer expansion plate 911 on the outer wall of the inner shaft 909 abuts against the outer expansion shaft 912, causing the expansion plate 904 to extend outwards, facilitating abutment against the expansion arc plate 10. When the sliding shaft 907 moves upwards under the action of the upper spring 914, the expansion is complete. At this time, due to the outward sliding expansion of the expansion arc plate 10, the abutment groove 913 will slide outwards along with the expansion arc plate 10. At this time, the abutment position of the abutment rod 908 and the connecting block 905 gradually changes. With the continuous displacement of the expansion arc plate 10, the top of the abutment rod 908 will be opposite to the abutment groove 913, causing the abutment rod 908 to lose its upward abutment. Under the action of the upper spring 914, the sliding shaft 907 moves upwards, and the sliding shaft 907 abuts against the inner shaft 909.This causes the inner shaft 909 to shift upwards, thereby disengaging the outer expansion plate 911 from the outer expansion shaft 912. The connecting block 905 then slides inwards under the action of the abutment spring 906. The connecting block 905 presses against the expanding plate 904, causing the expanding plate 904 to shift inwards. The expanding arc plate 10 is in a contracted state. When the expanding arc plate 10 contracts inwards, the connecting block 905 shifts inwards, and the abutment rod 908 is subjected to inward pressure from the abutment groove 913. This causes the abutment rod 908 to slide downwards, and the inner wall of the abutment groove 913 abuts against the top inclined surface of the abutment rod 908, thus causing the abutment rod 908 to... Sliding downwards, the sliding shaft 907 disengages from the inner shaft 909, resetting the sliding shaft 907. After the connecting block 905 resets, the top of the abutment rod 908 abuts against the bottom of the connecting block 905 again. The connecting block 905 restricts the upward displacement of the abutment rod 908 and the sliding shaft 907. Simultaneously, to prevent the expanding plate 904 from sliding outwards when it disengages from the inner shaft 909, thus preventing its outer wall from abutting against the connecting block 905 and causing the expanding arc plate 10 to extend outwards again, this device uses friction grooves on the outer wall of the expanding plate 904. When the sliding shaft 907 slides out of the interior of the expanding shaft 902, and the sliding shaft 907 disengages from the inner shaft 909, the expanding plate 904, due to the friction texture on its outer wall, can slide downwards while the inner shaft 909 slides downwards. When the outer expanding plate 911 pushes against the expanding plate 904 and slides outwards, it slows down the repositioning and sliding out of the expanding plate 904, thereby limiting the sliding speed of the expanding plate 904. This prevents the expanding plate 904 from immediately pushing against the connecting block 905 after the sliding shaft 907 has returned to its original position, causing the expanding arc plate 10 to extend out again for expanding the hole. After the expanding is complete and the device pulls out of the hole, the downward pressure spring 910 then drives... The inner shaft 909 completes its downward displacement, causing the outer expansion plate 911 to re-abut against the outer expansion shaft 912. Through the installation of the sliding shaft 907, during normal drilling, the sliding shaft 907 is in a relatively fixed state, breaking the ground for easy drilling. After drilling and expansion are completed, the sliding shaft 907 moves inward, causing the expansion plate 904 to contract and the expansion arc plate 10 to reset. This prevents soil stretching caused by the expansion arc plate 10 being extended when the drilling cylinder 9 is pulled out of the hole, thus avoiding the collapse of the hole's inner wall due to the pulling out of the drilling cylinder 9.

[0028] As attached Figure 1 and attached Figure 6As shown, a seeding box 13 is installed in the middle of the base 1 and is located at the rear end of the punching cylinder 9. A seeding control block 14 is slidably connected to the bottom of the seeding box 13, and the seeding control block 14 is in communication with the interior of the seeding box 13. The seeding control block 14 of this device can be any existing seeder that can realize the seeding function, which will not be described in detail here. The seeding box 13 enables automatic seeding after punching. The sliding adjustment of the seeding control block 14 allows this device to seed at different intervals for holes with different spacings, meeting diverse needs.

[0029] As attached Figure 1 and attached Figure 8 As shown, it includes a cover component, which includes a drive shaft 11 and a cleaning roller 12. The drive shaft 11 is driven and connected to the drive shaft 3, and the cleaning roller 12 is slidably connected to the outer wall of the drive shaft 11.

[0030] As attached Figure 1 and attached Figure 7 As shown, a linkage shaft 15 is rotatably connected to one end of the top of the base 1. A drive bevel gear 1501 is fixedly installed on the outer wall of the linkage shaft 15. The drive bevel gear 1501 meshes with the drive bevel gear 301. The drive bevel gear 301 is installed on the outer wall of the drive shaft 3. The linkage shaft 15 is driven to the drive shaft 11 via the linkage belt 1502.

[0031] As attached Figure 1 and attached Figure 7-8 As shown, a cleaning spring 1101 is fixedly installed on the outer wall of the drive shaft 11, and the other end of the cleaning spring 1101 is fixedly connected to the bottom of the base 1. There are two sweeping rollers 12. The two sweeping rollers 12 are connected to a connecting frame 1102 via bearings. A descending shaft 1103 is fixedly installed on the outer wall of the connecting frame 1102. The top of the descending shaft 1103 matches the sweeping eccentric wheel 5. When the drive shaft 3 rotates, the device will synchronously drive the transmission shaft 11 to rotate through the linkage shaft 15, so that the transmission shaft 11 drives the sweeping rollers 12 to rotate. The sweeping rollers 12 fill the soil on the outer wall of the hole into the hole, realizing the function of automatic covering. At the same time, in order to avoid the sweeping rollers 12 from spinning idly, the descending shaft 1103 of the device can drive the sweeping rollers 12 to descend, so that they rotate in contact with the ground. When rotating, the sweeping rollers 12 are located on the outer wall of the hole.
