DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and understandable, the utility model will be further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model. Embodiment one

[0024] To solve the technical problems in the background art, the following chassis structure for small transplanting machine is given:

[0025] In combination with Figures 1-4As shown, the chassis structure of the small transplanting machine comprises a running wheel 2 supporting a vehicle frame 1, an operation table 4 and shelves 5 on both sides of the vehicle frame 1 for loading plants to be transplanted, and a transplanting mechanism 3 arranged below the vehicle frame 1 for turning over the soil synchronously with the forward movement of the transplanting machine. The vehicle frame 1 comprises a towing handle 11 extending upward from the head, which can be connected to a power device for forward movement. The root of the towing handle 11 is symmetrically provided with two circular transplanting discs 12, and a semi-open transplanting gun 14 is arranged below the transplanting discs 12 for conveying the transplanted plants. The front part of the transplanting gun 14 is provided with an oblique soil breaking shovel 13 for breaking up the hardened soil as the transplanting machine moves forward. The transplanting mechanism 3 comprises a transplanting roller 33 arranged on the transplanting disc 12, wherein a plurality of cylindrical transplanting bins 331 are arranged in a ring shape and are connected with the transplanting gun 14, so that the transplanted plants can be loaded into the transplanting gun 14 for transplanting. The bottom of the transplanting roller 33 is sleeved with a multi-stage chain belt 32, and a ring-shaped hollow soil turning wheel 31 is suspended behind the vehicle frame 1. The outer periphery of the soil turning wheel 31 is provided with cylindrical soil inserting guns 311 at intervals, and the side of the soil inserting gun 311 is provided with an L-shaped soil lifting tooth 312. As the transplanting machine moves forward, the soil turning wheel 31 rotates synchronously to drive the transplanting roller 33 to rotate and discharge.

[0026] Through the above technical scheme, the embodiment introduces an optimized chassis structure of a small transplanting machine, which aims to overcome the problems of low transplanting efficiency, insufficient soil treatment and inconvenient operation in the prior art. The chassis structure is composed of a vehicle frame 1, a running wheel 2, an operation table 4, shelves 5 and a transplanting mechanism 3, and the specific design is as follows:

[0027] Firstly, the vehicle frame 1 is designed to be stable and lightweight, made of high-strength steel to ensure the overall carrying capacity and durability. The operation table 4 is installed on the top of the vehicle frame 1, which is designed in accordance with ergonomics, and the operator can comfortably transplant and feed. The shelves 5 are arranged on both sides of the operation table 4 for storing and loading the plants to be transplanted. The shelves 5 have a reasonable structure, which can effectively increase the storage capacity, reduce the frequent loading and unloading during operation, and improve the work efficiency.

[0028] Secondly, the towing handle 11 is upwardly extended at the front of the chassis, which is designed to connect various power devices to realize the forward and backward movement of the transplanting machine. The root of the towing handle 11 is symmetrically provided with two circular transplanting discs 12 to ensure the stability and balance of the plant conveying during transplanting. The semi-open transplanting gun 14 is installed below the transplanting disc 12, and the front part of the transplanting gun 14 is equipped with an oblique soil breaking shovel 13. As the transplanting machine moves forward, the soil breaking shovel 13 can effectively break up the hardened soil, improve the efficiency of turning over the soil, and ensure the loosening of the soil and the smooth transplanting of the plants.

[0029] Next, the transplanting mechanism consists of three parts. A transplanting roller 33 is mounted on the transplanting tray 12. Multiple cylindrical transplanting chambers 331 are arranged on the roller. These chambers 331 can rotate circumferentially and communicate with the transplanting gun 14, ensuring that the plant can be smoothly transported to the designated position along the transplanting gun 14. A multi-stage chain belt 32 is fitted at the bottom of the transplanting roller 33. The chain belt has a multi-stage transmission structure, which improves the traction and stability of the transplanting roller 33.

[0030] A hollow annular soil-turning wheel 31 is suspended rearward along the frame 1. Cylindrical soil-inserting guns 311 are spaced apart on the outer circumference of the soil-turning wheel 31, and L-shaped soil-lifting teeth 312 are equipped on the sides of the soil-inserting guns 311. This design allows the soil-inserting guns 311 to effectively insert into the soil and turn it over during the rotation of the soil-turning wheel 31, while the soil-lifting teeth 312 further loosen the soil, ensuring the comprehensiveness and uniformity of the soil-turning process. The coordinated work of the soil-turning wheel 31 and the transplanting roller 33 achieves synchronous soil turning and rotating material feeding, significantly improving the efficiency of soil treatment and the accuracy of transplanting.

[0031] In summary, the small transplanter of this embodiment achieves efficient coordination between soil turning and plant transplanting, solving problems such as incomplete soil treatment, unstable plant delivery, and complex operation in existing technologies. It not only improves transplanting efficiency and work quality, but also enhances the adaptability and ease of operation of the equipment. It is suitable for various complex terrains and different types of soil environments, and has broad application prospects and market competitiveness. Example 2

[0032] like Figures 1-3 As shown, based on the above embodiments, this embodiment further provides the following:

[0033] In this embodiment, the transplanter 14 is provided with comb-shaped soil-combing teeth 15 on both sides from front to back, which can break up large clumps of soil as the transplanter moves forward, for efficient insertion of transplanted plants.

[0034] The outer edges of the comb teeth 15 are clamped with arched soil wings 34 that can rotate up and down. These wings can narrow the soil and straighten the transplanted plants as the transplanter moves forward, ensuring the correct orientation of the transplanted plants when they are planted.

[0035] The lower part of the transplanter 14 is a semi-open rotatable design, and a hinge shaft 16 is connected to the frame 1. It can rotate backward as the transplanter moves forward to block stones from entering the transplanting pit and guide debris to both sides.

[0036] Through the above technical solution, this embodiment introduces an improved small transplanter, aiming to solve the problems of insufficient soil breaking, inaccurate plant insertion, and interference from debris in existing transplanting equipment. The core improvement of this transplanter focuses on the design of the transplanting gun 14, and the specific implementation steps and structure are as follows:

[0037] First, the transplanting gun 14 is equipped with comb-shaped soil-combing teeth 15 on both sides, arranged sequentially from front to back in a comb-like structure. As the transplanter moves forward, the teeth 15 effectively break up large clumps of compacted soil, increasing soil looseness. This design ensures a suitable soil environment for plant root growth in the transplanting area, improving plant survival rate and health. Simultaneously, the optimized structure of the teeth 15 improves soil processing efficiency and reduces energy consumption during operation.

[0038] Secondly, rotatable arched soil wings 34 are installed on both outer edges of the soil comb teeth 15. These arched soil wings 34 automatically adjust their angle according to soil conditions as the transplanter moves forward, narrowing the soil space and evenly positioning the transplanted plants within the transplanting pit. This effectively ensures that the plants maintain the correct posture after being inserted into the soil, preventing them from tilting or slipping, thus improving the accuracy and stability of the transplanting. The movable design of the arched soil wings 34 enhances the equipment's adaptability to different soil densities, ensuring a smooth transplanting process.

[0039] Furthermore, the lower part of the transplanting gun 14 is designed as a semi-open, rotatable structure, connected to the frame 1 via a hinge shaft 16. This design allows the transplanting gun 14 to rotate backward as the transplanter moves forward, effectively preventing stones and other debris from entering the transplanting pit. The semi-open structure not only prevents damage to the plant roots from hard objects but also guides debris to both sides, avoiding the accumulation and blockage of debris during transplanting. This structure ensures a clean transplanting environment and the safety of the plants, improving the survival rate of transplanted plants.

[0040] In actual operation, after the operator starts the transplanter, the equipment drives the transplanter forward through the traction system. As the transplanter moves forward, the comb teeth 15 break up and comb the soil, and the arched wings 34 adjust the soil flow direction to ensure precise insertion of the plants. At the same time, the semi-open transplanter gun 14 rotates to divert and block debris, maintaining the ready-to-transplant state in the transplanting pit. This series of coordinated actions makes the transplanting process efficient, precise, and stable.

[0041] In summary, this embodiment demonstrates significant advantages in soil breaking, plant insertion, and debris management, addressing several shortcomings of existing technologies. It not only improves transplanting efficiency and quality but also enhances the equipment's adaptability to complex terrain and different soil conditions, meeting the needs of efficient and precise operations in modern agriculture and ensuring the robust growth of transplanted plants. Example 3

[0042] like Figure 4 As shown, based on the above embodiments, this embodiment further provides the following:

[0043] In this embodiment, the shaft portion of the soil turning wheel 31 is provided with a shock absorbing spring 35 with an embedded spring, the top of which is connected with the vehicle frame 1 and can reduce the shaking and jolting of the vehicle frame 1 as the transplanting machine advances.

[0044] The top of the shock absorbing spring 35 is provided with an adjusting nut 351, and rotating the adjusting nut 351 can change the stroke of the shock absorbing spring 35, so as to meet the tightness of the soil of different transplanted plants.

[0045] Through the above technical scheme, the embodiment introduces an optimized small transplanting machine, which is particularly aimed at the shaking and jolting of the vehicle frame 1 in the prior art during the transplanting process and the inability to adapt to different soil tightness.

[0046] Firstly, the shock absorbing spring 35 with an embedded spring is installed at the upward extending portion of the shaft of the soil turning wheel 31. The design purpose of the shock absorbing spring 35 is to effectively absorb the vibration and impact generated during the operation of the transplanting machine, thereby reducing the shaking and jolting of the vehicle frame 1. This structure significantly improves the comfort of the operator and the stability of the equipment, ensuring the smooth progress of the transplanting process. In addition, the shock absorbing spring 35 is made of high-elasticity material, has excellent durability and response speed, and can maintain stable performance in various working environments.

[0047] Secondly, the top of the shock absorbing spring 35 is provided with an adjusting nut 351, and the operator can change the stroke length of the shock absorbing spring 35 by rotating the adjusting nut 351. This adjusting mechanism enables the transplanting machine to be flexibly adjusted according to the needs of different transplanted plants and the tightness of the soil. When the soil is relatively hard, the stroke of the shock absorbing spring 35 is lengthened to provide greater cushioning; on the contrary, when the soil is relatively loose, the stroke is shortened to enhance the response sensitivity of the equipment. This adjusting function significantly improves the adaptability of the transplanting machine to various soil conditions, ensuring that the plants can be transplanted into the soil in the best posture.

[0048] In actual operation, the operator can quickly adjust the stroke length of the shock absorbing spring 35 by simply rotating the adjusting nut 351 according to the current soil conditions, so as to change the soil turning depth of the soil turning wheel 31, ensuring the stability and accuracy during the transplanting process.

[0049] In summary, the embodiment not only effectively reduces the shaking and jolting of the vehicle frame 1, improves the stability and comfort of the operation, but also realizes the adaptation to different soil tightness through the adjusting device, further improving the overall performance and operation convenience of the equipment.

[0050] The working principle and use process of the utility model are as follows:

[0051] Device preparation and installation

[0052] The operator first loads the plants to be transplanted onto the shelves 5 on both sides of the frame 1 in an orderly manner, ensuring that each plant is securely fixed on the shelves 5 to prevent displacement or tipping during movement. Then, climb onto the operating platform 4 to check that all mechanisms are functioning properly.

[0053] Connecting the power device

[0054] Connect the transplanter to the power device, such as a tractor or animal power, through the traction handle 11, ensuring smooth power transmission. Adjust the connection point of the traction handle 11 to ensure stable connection between the transplanter and the power source, avoiding loosening during operation.

[0055] Adjusting the damping system

[0056] According to the current soil hardness, rotate the adjusting nut 351 at the top of the damping spring 35 to adjust the stroke length of the damping spring 35. For harder soil, appropriately extend the stroke of the damping spring 35 to provide more cushioning; for softer soil, shorten the stroke to enhance the responsiveness of the device, ensuring smoothness and accuracy of operation.

[0057] Starting the transplanter and advancing

[0058] Start the power device and slowly push the transplanter forward. The transplanter's travel wheels 2 begin to operate, driving the entire device forward. As it advances, the transplanting mechanism 3 below the transplanter is simultaneously started, performing soil turning and plant transplanting operations.

[0059] Soil breaking and plant insertion

[0060] The oblique soil breaking shovel 13 at the front of the transplanting gun 14 begins to work, breaking up the hardened soil and ensuring that the soil in the transplanting area is loose. The comb-shaped soil comb 15 breaks up large pieces of soil from front to back, further improving the looseness of the soil and facilitating efficient insertion of the plants. At the same time, the soil arching wing 34 automatically rotates up and down, narrowing the soil space and straightening the plants, ensuring that the plants enter the soil in the correct posture.

[0061] Obstacle handling and debris flow guidance

[0062] The semi-open lower part of the transplanting gun 14 rotates backward as the transplanter advances, effectively blocking stones and other debris from entering the transplanting pit. At the same time, through the design of the hinged shaft 16, the debris flow is guided to both sides, avoiding blockage and damage to plant roots during transplantation, maintaining the cleanliness and smoothness of the transplanting area.

[0063] Synchronous soil turning and feeding

[0064] The multi-stage chain belt 32 on the transplanting roller 33 works in cooperation with the annular hollow soil turning wheel 31, the cylindrical soil inserting gun 311 and the L-shaped soil lifting tooth 312 of the soil turning wheel 31 rotate synchronously, the soil is further loosened, and the transplanting roller 33 is rotated to unload. In this way, the soil is uniformly loosened, the plants are smoothly unloaded into the soil, the synchronization of soil turning and transplanting is realized, and the operation efficiency and the transplanting quality are improved.

[0065] Completion of transplanting and equipment shutdown

[0066] After the completion of the transplanting operation in the predetermined area, the forward movement of the transplanting machine is slowly stopped. The connection between the traction handle 11 and the power device is disconnected to ensure that the equipment is safely parked. Finally, the equipment is simply cleaned and maintained for the next use.

[0067] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
