Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to a seedling root loosening machine. Background Technology

[0002] Loose, well-aerated, and well-drained soil is the ideal soil texture for seedling planting. To facilitate planting seedlings, allow their roots to spread out in the soil, and make it easier for them to absorb water, thus promoting seedling growth, it is usually necessary to loosen the soil with a soil loosening machine before planting. This makes the soil looser and more aerated. The use of a soil loosening machine is a prerequisite for seedling planting, greatly improving the survival rate of seedlings and making planting easier.

[0003] Currently, during the use of soil rippers, the shovel head used to loosen the soil is in contact with the soil for a long time. When the soil is relatively moist, a lot of soil will stick to the shovel head. The soil adhesion brings certain resistance to the rotation of the shovel head, which makes the machine driving the shovel head consume more energy. In addition, the long-term operation of the shovel head makes the equipment driving the shovel head prone to overheating, which may lead to damage to the equipment, thus posing certain hidden dangers to the use of soil rippers.

[0004] Therefore, it is necessary to provide a seedling root loosening machine to solve the above-mentioned technical problems. Summary of the Invention

Installed on circular long rods 25 and 26, two bevel gears 27 mesh with each other. An isolation box 24 isolates and protects the two bevel gears 27. Multiple loosening plow teeth 28 are fixedly fitted onto the circular long rod 26. Two placement racks 29 are fixedly installed at the bottom of the machine casing 1. A positioning frame 30 is fixedly installed on one side of the right placement rack 29. The same water storage tank 31 is slidably installed on both placement racks 29. The right side of the water storage tank 31 contacts the positioning frame 30. The bottom inner wall of the water storage tank 31 is higher on both sides and lower in the middle to facilitate sewage discharge and reduce residue in the water storage tank 31. An inlet / outlet hole 32 is opened at the top of the water storage tank 31, aligned with a rectangular hole 8 on the right side. Both placement racks 29 are screwed... The water tank 31 is fitted with positioning screws 33, the tops of which are slidably connected to the bottom of the water tank 31. A horizontal plate 34 is slidably mounted on the water tank 31, extending to the outside of the water tank 31 on the left side. A waterproof plate 35 is fixedly mounted on the right end of the horizontal plate 34, which is compatible with the inlet / outlet hole 32 and can block the inlet / outlet hole 32 to prevent water from splashing out of the water tank 31. A connecting rod 36 is fixedly mounted on the end of the horizontal plate 34 away from the waterproof plate 35. Two wedge-shaped grooves 37 are formed on the same side of the horizontal plate 34. A side block 38 is fixedly mounted on the left side of the water tank 31, and a sliding rod 39 is slidably mounted on the side block 38. The sliding rod 39 is L-shaped and is slidably mounted in the wedge-shaped groove 37 on the left side.A spring 40 is fitted onto the sliding rod 39.

[0036] In order to provide sufficient space for the circular rod 3 and prevent the adjusting block 4 from falling off the circular rod 3, in this method, the adjusting block 4 is provided with a longitudinal hole, the circular rod 3 is slidably installed in the longitudinal hole, a lifting handle is fixedly installed on one side of the sealing plate 5, and two square blocks are fixedly installed on one side of the housing 1. A pull rod is rotatably installed between the two square blocks, and the equipment can be easily moved by pulling the pull rod.

[0037] To reduce wear on the circular block 10 and to reserve space for the installation of the adapter block 11, in this method, multiple rolling balls 1 are embedded on the inner wall of the annular block 9, and all of the rolling balls 1 are in contact with the circular block 10. Multiple rolling balls 2 are embedded on the bottom of the circular block 10, and all of the rolling balls 2 are in contact with the bottom inner wall of the chassis 1. A circular groove is provided on the bottom of the circular block 10, and the circular groove is adapted to the adapter block 11.

[0038] In order to limit the movement tendency of the two sliding blocks 19 and increase the stability of the two sliding blocks 19, in this method, in the two adjustment mechanisms, two vertical rods are fixedly installed on the top inner wall of the two mounting brackets 17, the bottom ends of the four vertical rods are fixedly connected to the top of the circular block 10, and the four vertical rods are slidably connected to the two sliding blocks 19 respectively.

[0039] To provide support for the waterproof membrane 35 and make its position more stable, in this method, a connecting rod is fixedly installed between the inner walls of both sides of the water storage tank 31. A roller is rotatably mounted on the connecting rod, and the roller contacts the bottom of the waterproof membrane 35. A positioning plate is fixedly installed on the bottom of the waterproof membrane 35. The positioning plate can control the sliding range of the waterproof membrane 35 and prevent the waterproof membrane 35 from sliding excessively. A water outlet is fixedly installed on the bottom of the water storage tank 31, and a water inlet is fixedly installed on one side of the water storage tank 31. Both the water outlet and the water inlet are threaded with sealing caps. The water inlet and the water outlet facilitate the replacement of the water stored in the water storage tank 31, and the sealing caps can prevent water from flowing out.

[0040] To prevent the two springs 40 from falling off the two sliding rods 39, in this method, anti-detachment blocks are fixedly installed at both ends of the sliding rods 39. Two circular grooves are opened at the bottom of the water tank 31, and the tops of the two positioning screws 33 are slidably installed in the two circular grooves respectively. The tops of the two positioning screws 33 are respectively inserted into the two circular grooves, which can fix the water tank 31 in the two placement racks 29.

[0041] In this embodiment

[0042] In the initial state, the water tank 31 is fixed to the bottom of the chassis 1 on two placement racks 29, the waterproof plate 35 covers the inlet and outlet holes 32, the water tank 31 is in a sealed state, and the two support racks 21 are located in the chassis 1.

[0043] Before using the soil loosening machine, first unscrew the sealing cap on the water inlet and inject an appropriate amount of clean water into the water storage tank 31 through the water inlet. Then, put the sealing cap back on the water inlet and tighten it. Next, pull the soil loosening machine using the lever to move it to the work site. Then, start the drive motor 3 22 and drive motor 2 18 located on the left. The output shaft of drive motor 3 22 drives the circular long rod 25 to rotate. Under the action of the two bevel gears 27, the circular long rod 25 drives the circular long rod 3 26 and multiple loosening plow teeth 28 simultaneously. The output shaft of the drive motor 18 rotates, causing the threaded rod 16 to rotate. The sliding block 19 drives the support frame 21 to move downward. The support frame 21 drives the multiple loosening plow teeth 28 located on the left side to move downward. As the loosening plow teeth 28 move, they gradually come into contact with the soil and break it up. After the sliding block 19 moves to an appropriate height, the drive motor 18 is turned off. The multiple loosening plow teeth 28 will maintain a fixed height and gradually stir the soil as the machine box 1 moves, so that the originally compacted soil is loosened.

[0044] After the multiple loosening plow teeth 28 on the left side have been working for a period of time, some soil clods will stick to them. The drive motor 3 22 will also get hot due to prolonged operation. At this time, the drive motor 2 18 can be restarted. The output shaft of the drive motor 2 18 will drive in the opposite direction, causing the support frame 21 to gradually move upward and back into the housing 1. During the movement of the support frame 21, the horizontal plate 34 can be pushed to the left by the connecting rod 36. The horizontal plate 34 drives the waterproof plate 35. While the horizontal plate 34 slides, it also moves the waterproof plate 35. The sliding rod 39 will generate a pushing force, causing it to slide on the side block 38, thereby compressing the spring 40 and deforming it. The sliding rod 39 will then gradually slide out of the wedge groove 37 on the left side until the other wedge groove 37 moves to one side of the sliding rod 39. Under the elastic force of the spring 40, the sliding rod 39 will automatically engage in the wedge groove 37. At this point, the control of the connecting rod 36 can be released, and the inlet and outlet holes 32 are now unobstructed by the waterproof plate 35.

[0045] Then turn off the second drive motor 18 on the left and then turn on the first drive motor 13. The first drive motor 13 drives the circular block 10 to rotate through the long circular rod 14, so that the positions of the two mounting brackets 17 are reversed. The multiple loosening plow teeth 28 that have just been used will be adjusted to the right side, while the loosening plow teeth 28 that were originally located on the right side and are on standby will be moved to the left side. Then, start the third drive motor 22 and the second drive motor 18 that are located on the left side in the same way, so that the standby loosening plow teeth 28 can be put into operation.

[0046] Restarting the drive motor 13, which has been moved to the right side, causes multiple rotating soil-loosening plow teeth 28 to enter the water tank 31 through the rectangular hole 8 and the inlet / outlet hole 32 on the right side. Most of the soil-loosening plow teeth 28 will move into the water tank 31 and be immersed in water. During the rotation of the soil-loosening plow teeth 28, the centrifugal force generated by the rotation and the friction of the water flow will clean the soil adhering to the soil-loosening plow teeth 28. After cleaning, restarting the drive motor 28 moves the soil-loosening plow teeth 28 to the housing 1 to enter the standby state. Then, turning off the drive motor 32 and drive motor 28 on the right side, and then pushing the connecting rod 36 to the right, the inlet / outlet hole 32 is covered with a waterproof plate 35 to prevent water from splashing out.

[0047] When cleaning the water tank 31 is required, the sealing cap on the outlet can be rotated off to drain the sewage. Then, rotate the two positioning screws 33 to remove the tops of the two positioning screws 33 from the bottom of the water tank 31. Without the restriction of the two positioning screws 33, the water tank 31 can be slid off the two placement racks 29. When it is necessary to check the internal condition of the chassis 1, push the sealing plate 5 upward by lifting the handle. The sealing plate 5 drives the adjusting block 4 to slide on the circular rod 3 until the bottom inner wall of the longitudinal hole contacts the circular rod 3. The bottom of the sealing plate 5 will slide off the limiting block 6. Then rotate the sealing plate 5. The sealing plate 5 will rotate around the circular rod 3 as the center. The sealing plate 5 will be gradually lifted up, and the opening at the front of the chassis 1 will gradually be unobstructed, exposing the internal condition of the chassis 1.

[0048] Compared with related technologies, the seedling root loosening machine provided by this invention has the following beneficial effects:

[0049] In this invention, two sets of 180° rotatable plow teeth 28 are installed inside the casing 1, enabling rapid switching between working and standby states, significantly improving operational continuity, and further ensuring equipment safety. During the operation of one set of plow teeth 28, the other set of plow teeth 28 can be automatically immersed in for cleaning, using centrifugal force and water flow to achieve automatic decontamination, reducing the frequency of manual cleaning, reducing the drive burden on the drive motors 22, and providing cooling and rest time for the two drive motors 22 to prevent overheating. The height of the plow teeth 28 on the left and right sides is independently controlled by the two drive motors 22, allowing the depth of the plow teeth 28 into the soil to be controlled as needed, thus improving the flexibility of equipment use.

[0050] Second embodiment:

[0051] Based on the seedling root loosening machine provided in the first embodiment of this application, the second embodiment of this application proposes another seedling root loosening machine. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0052] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0053] Please refer to the following: Figures 11-13 In the seedling root loosening machine, a U-shaped rod 41 is fixedly installed on one side of the machine box 1. A mounting block 42 is rotatably sleeved on the U-shaped rod 41. An installation groove is opened on the mounting block 42, and a hydraulic cylinder 43 is fixedly installed in the installation groove. A connecting block 44 is fixedly installed on the output rod of the hydraulic cylinder 43, and a receiving block 45 is rotatably installed on the connecting block 44. A U-shaped rod 46 is fixedly installed on one side of the machine box 1. An annular tube 47 is rotatably sleeved on the U-shaped rod 46. The annular tube 47 fits against the right side of the machine box 1. A connecting plate 48 is fixedly installed on the annular tube 47, and the bottom of the receiving block 45 is... The top of the connecting plate 48 is fixedly connected, and the bottom of the connecting plate 48 is fixedly installed with rake teeth 49. The rake teeth 49 consists of a long strip plate and multiple longitudinal rods. The long strip plate is fixed to the bottom of the connecting plate 48, and the multiple longitudinal rods are distributed in a rectangular array and fixedly installed at the bottom of the long strip plate. The multiple longitudinal rods are made of stainless steel, which is tough, rust-proof, and has a long service life. A protective plate 50 is fixedly installed on one side of the chassis 1. The protective plate 50 can isolate the rake teeth 49 when the rake teeth 49 are retracted, wrapping the rake teeth 49 inside and reducing the safety hazards of the rake teeth 49.

[0054] To increase the stability of the protective plate 50 installation, in this method, two reinforcing rods are fixedly installed on the top of the protective plate 50, and both reinforcing rods are fixedly connected to one side of the chassis 1.

[0055] In this embodiment

[0056] In normal operation, the output rod of hydraulic cylinder 43 is retracted, the connecting plate 48 is retracted, and the rake teeth 49 are located below the protective plate 50, protected by the protective plate 50 to prevent damage from the sharp parts of the rake teeth 49. Before the soil loosening machine is in operation, hydraulic cylinder 43 is started first. The output rod of hydraulic cylinder 43 will gradually extend outward, and the mounting block 42 will rotate on the U-shaped rod 41. The connecting block 44 and the receiving block 45 will make rotational contact. The connecting plate 48 will be pushed by external force and rotate clockwise around the U-shaped rod 46. The connecting plate 48 drives the rake teeth 49 until the output rod of hydraulic cylinder 43 is fully extended. The position of the rake teeth 49 will be leveled, and hydraulic cylinder 43 will automatically shut down. During the movement of the machine box 1, the loosened soil makes the ground uneven. When the rake teeth 49 pass over the turned soil, they can smooth the soil and keep the ground orderly and regular, which is convenient for the next step of planting seedlings.

[0057] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention.
