Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and particularly relates to a seedling root soil loosener. Background Art

[0002] Soil that is loose, breathable, and well-drained is the most ideal soil texture for seedling planting. In order to facilitate the planting of seedlings, enable the roots of the seedlings to stretch in the soil, absorb water in the soil, and be more conducive to the growth of seedlings, usually, before planting seedlings, it is necessary to use a soil loosener to loosen the soil to make it more loose and breathable. The use of a soil loosener is a prerequisite for seedling planting, which greatly improves the survival rate of seedlings and also facilitates the planting of seedlings.

[0003] At present, during the use of the soil loosener, the shovel head for loosening the soil is in contact with the soil for a long time. When the soil is relatively moist, a large amount of soil will adhere to the shovel head. The adhesion of the soil brings a certain resistance to the rotation of the shovel head, causing the machine driving the shovel head to 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, posing certain potential hazards in the use of the soil loosener.

Two placement frames 29 are fixedly installed at the bottom of the chassis 1. A positioning frame 30 is fixedly installed on one side of the placement frame 29 on the right side. The same water storage tank 31 is slidably installed on the two placement frames 29. The right side of the water storage tank 31 is in contact with the positioning frame 30. The two sides of the inner wall at the bottom of the water storage tank 31 are higher and the middle is lower, which is convenient for sewage discharge and reduces the residue in the water storage tank 31. An access hole 32 is opened at the top of the water storage tank 31. The access hole 32 is aligned with the rectangular hole 8 on the right side. Positioning screws 33 are threadedly installed on both of the two placement frames 29. The tops of the two positioning screws 33 are slidably connected to the bottom of the water storage tank 31. A transverse plate 34 is slidably installed on the water storage tank 31. The left side of the transverse plate 34 extends outside the water storage tank 31. A waterproof plate 35 is fixedly installed at the right end of the transverse plate 34. The waterproof plate 35 is adapted to the access hole 32. The waterproof plate 35 can block the access hole 32 to prevent the water in the water storage tank 31 from splashing out. A connecting rod 36 is fixedly installed at the end of the transverse plate 34 away from the waterproof plate 35. Two wedge-shaped grooves 37 are opened on the same side of the transverse plate 34. A side block 38 is fixedly installed on the left side of the water storage tank 31. A sliding rod 39 is slidably installed on the side block 38. The sliding rod 39 is L-shaped and is slidably installed in the wedge-shaped groove 37 on the left side.A spring 40 is sleeved on the sliding rod 39.

[0022] In order to reserve sufficient moving space for the circular rod 3 and prevent the adjusting block 4 from falling off the circular rod 3, in this solution, a longitudinal hole is formed in the adjusting block 4, and the circular rod 3 is slidably installed in the longitudinal hole. One side of the sealing plate 5 is fixedly installed with a handle, and two square blocks are fixedly installed on one side of the chassis 1. A pull rod is rotatably installed between the two square blocks, and the pull rod facilitates pulling the device to move.

[0023] In order to reduce the wear on the circular block 10 and reserve installation space for the adapter block I 11, in this solution, a plurality of first rolling beads are embedded on the inner wall of the annular block 9, and the plurality of first rolling beads are all in contact with the circular block 10. A plurality of second rolling beads are embedded at the bottom of the circular block 10, and the plurality of second rolling beads are all in contact with the bottom inner wall of the chassis 1. A circular groove is formed at the bottom of the circular block 10, and the circular groove is adapted to the adapter block I 11.

[0024] In order to limit the moving tendency of the two sliding blocks 19 and increase the stability of the two sliding blocks 19, in this solution, in the two adjusting mechanisms, two vertical rods are fixedly installed on the top inner walls of the two mounting frames 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 respectively slidably connected to the two sliding blocks 19.

[0025] In order to support the waterproof plate 35 and make the position of the waterproof plate 35 more stable, in this solution, the same connecting rod is fixedly installed between the two inner walls on both sides of the water storage tank 31. A round roller is rotatably sleeved on the connecting rod, and the round roller is in contact with the bottom of the waterproof plate 35. A positioning plate is fixedly installed at the bottom of the waterproof plate 35. The positioning plate can control the sliding range of the waterproof plate 35 and prevent the waterproof plate 35 from sliding excessively. An outlet is fixedly installed at the bottom of the water storage tank 31, and an inlet is fixedly installed on one side of the water storage tank 31. Sealing caps are threadedly sleeved on the outlet and the inlet. The inlet and the outlet facilitate the replacement of the stored water in the water storage tank 31, and the sealing caps can prevent water from flowing out.

[0026] In order to prevent the two springs 40 from falling off the two sliding rods 39, in this solution, anti - detachment blocks are fixedly installed at both ends of the sliding rod 39. Two circular grooves are formed at the bottom of the water storage tank 31. The tops of the two positioning screws 33 are respectively slidably installed in the two circular grooves, and the tops of the two positioning screws 33 are respectively clamped into the two circular grooves, so as to fix the water storage tank 31 in the two placement frames 29.

[0027] In this embodiment In the initial state, the water storage tank 31 is located on the two placement frames 29 and is fixed to the bottom of the chassis 1. The waterproof plate 35 blocks the access hole 32. The water storage tank 31 is in a sealed state, and the two support frames 21 are both located in the chassis 1.

[0028] Before using the soil loosener to loosen the soil, first rotate and remove the sealing cover on the water inlet, inject an appropriate amount of clean water into the water storage tank 31 through the water inlet, then put the sealing cover back on the water inlet and tighten it. After that, pull the soil loosener through the pull rod to move the soil loosener to the working location. Then start the drive motor three 22 and drive motor two 18 located on the left side. The output shaft of the drive motor three 22 drives the circular long rod two 25 to rotate. Under the combined action of the two bevel gears 27, the circular long rod two 25 drives the circular long rod three 26 and multiple soil loosening teeth 28 to rotate simultaneously. The output shaft of the drive motor two 18 drives the threaded rod 16 to rotate, and the sliding block 19 drives the support frame 21 to move downward. The support frame 21 drives multiple soil loosening teeth 28 in the rotating state on the left side to move downward. During the movement of the soil loosening teeth 28, they gradually come into contact with the soil and break up the soil while in contact with the soil. After the sliding block 19 moves down to an appropriate height, the drive motor two 18 is turned off, and multiple soil loosening teeth 28 will maintain a fixed height. During the movement of the chassis 1, the soil is gradually stirred and loosened so that the originally compacted soil is broken up and loosened.

[0029] After multiple soil loosening teeth 28 on the left side work for a period of time, some soil blocks will adhere to the multiple soil loosening teeth 28, and the drive motor three 22 will also heat up due to long-term driving. At this time, the drive motor two 18 can be started again. The output shaft of the drive motor two 18 will drive in the reverse direction, driving the support frame 21 to gradually move upward and back into the chassis 1. During the movement of the support frame 21, the connecting rod 36 can be used to push the transverse plate 34 to move leftward. The transverse plate 34 drives the waterproof plate 35. While the transverse plate 34 slides, it will generate a driving force on the sliding rod 39, causing the sliding rod 39 to slide on the side block 38, thereby squeezing the spring 40 and deforming the spring 40. The sliding rod 39 gradually slides out of the wedge-shaped groove 37 on the left side until the other wedge-shaped groove 37 moves to one side of the sliding rod 39. Under the action of the elastic force of the spring 40, the sliding rod 39 will automatically snap into this wedge-shaped groove 37. At this time, the control of the connecting rod 36 can be released, and the inlet and outlet holes 32 and the unobstructed state without the waterproof plate 35 blocking are in an unobstructed state.

[0030] Then turn off the drive motor two 18 on the left side, and immediately start the drive motor one 13. The drive motor one 13 drives the circular block 10 to rotate through the circular long rod one 14, causing the positions of the two mounting brackets 17 to be swapped. The multiple soil loosening teeth 28 that have just been used will be adjusted to the right side, and the originally unused soil loosening teeth 28 on the right side will be moved to the left side. Then start the drive motor three 22 and drive motor two 18 located on the left side in the same operation mode, so that the unused soil loosening teeth 28 can be put into operation.

[0031] Restart the drive motor 13 that has been moved to the right after use. The multiple loosening plow teeth 28 in the rotating state will enter the water storage tank 31 through the rectangular hole 8 and the inlet and outlet hole 32 on the right side. Most of the loosening plow teeth 28 will move into the water storage tank 31 and be immersed in the water. During the rotation of the loosening plow teeth 28, with the centrifugal force generated by the rotation and the friction of the water flow, the soil blocks adhered to the loosening plow teeth 28 are cleaned. After the cleaning is completed, restart the drive motor 18. Move the loosening plow teeth 28 into the chassis 1 to enter the standby state, and turn off the drive motor 3 22 and the drive motor 18 on the right side. Then, push the connecting rod 36 to the right and block the inlet and outlet hole 32 with the waterproof plate 35 to prevent water from splashing out.

[0032] When the water storage tank 31 needs to be cleaned subsequently, the sealing cover on the water outlet can be rotated and removed, and the sewage can be discharged through the water outlet. Then, rotate the two positioning screws 33 so that the tops of the two positioning screws 33 move out from the bottom of the water storage tank 31. Without the restriction of the two positioning screws 33, the water storage tank 31 can be slid off the two placement racks 29. When it is necessary to check the internal situation of the chassis 1, push the sealing plate 5 upward through the handle. The sealing plate 5 drives the adjustment 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 out from the limiting block 6. Then, rotate the sealing plate 5, and the sealing plate 5 will rotate around the circular rod 3 as the center. The sealing plate 5 will be gradually lifted, and the opening in front of the chassis 1 will gradually lose its cover, and the internal situation of the chassis 1 will be exposed.

[0033] Compared with the related technology, the seedling root loosening machine provided by the present invention has the following beneficial effects: In the present invention, two sets of loosening plow tooth 28 assemblies that can be rotated and adjusted by 180° are arranged in the chassis 1 to realize the rapid switching between the working state and the standby state, significantly improving the operation continuity and further ensuring the safety of the equipment. During the operation of one set of loosening plow tooth 28 assemblies, the other set of loosening plow tooth 28 assemblies can be automatically cleaned in an immersion manner, and automatic decontamination is realized by using centrifugal force and water flow scouring, reducing the manual cleaning frequency and reducing the driving burden of the drive motor 3 22, providing cooling and rest time for the two drive motors 3 22, preventing the drive motor 3 22 from overheating. The heights of the loosening plow teeth 28 on the left and right sides are independently controlled by the two drive motors 3 22, and the depth of the loosening plow teeth 28 entering the soil can be controlled according to needs, improving the flexibility of equipment use.

[0034] Second Embodiment: Based on the seedling root loosening machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another seedling root loosening machine. The second embodiment is only an optimized way of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

Protected by the protective plate 50, the sharp part of the harrow tooth 49 is avoided from causing harm. Before the loosening machine operates, first start the hydraulic cylinder 43. The output rod of the hydraulic cylinder 43 will gradually extend outwards. The sleeve block 42 will rotate on the U-shaped rod 41, and rotational contact will occur between the connecting block 44 and the receiving block 45. The connecting plate 48 will be pushed by an external force and rotate clockwise around the U-shaped rod 46. The connecting plate 48 drives the harrow tooth 49 until the output rod of the hydraulic cylinder 43 is fully extended. The position of the harrow tooth 49 will be leveled, and the hydraulic cylinder 43 will automatically close. During the movement of the chassis 1, the loosened soil makes the ground uneven. When the harrow tooth 49 passes through the turned-up soil, it can comb the soil flat, keep the ground orderly and regular, and facilitate the next step of seedling planting.
