Description

Technical Field

[0001] This utility model relates to the field of understory planting, and more specifically, to a land preparation device for understory planting. Background Technology

[0002] Understory planting is an ecological agricultural model that utilizes the complementary resources of the "canopy layer" and "understory space" in forest land. Without damaging the forest ecosystem, suitable crops, cash crops, or medicinal plants are planted under the forest to achieve a three-dimensional and integrated management of "forest" and "agriculture," thus achieving a win-win situation for ecological protection and economic benefits.

[0003] According to the prior art, Chinese patent publication number CN209185030U discloses "a digging, shaking and land preparation device for a self-propelled scallion combine harvester", which includes a frame, a depth limiting device, a digging device, a shaking device and a land preparation device. The land preparation device includes an auger support rod hinged to the frame and an auger roller mounted on the auger cover. A land preparation motor connected to the auger roller is fixed on the auger cover, and an adjusting bolt that passes upward through the frame is also hinged on the auger cover. This invention uses a depth-limiting device to control the digging depth and travel direction, facilitating the accurate operation of the digging, soil-shaking, and land-leveling device. The digging device breaks the soil, quickly and completely excavating the scallions, improving digging efficiency. The soil-shaking device removes most of the soil from the scallion roots, increasing the clean soil rate of the harvest. The land-leveling device plows and sun-dries the scallion field in advance, helping to eliminate pests and diseases. This invention achieves the digging, soil-shaking, and land-leveling operations for scallions, improving harvesting efficiency and quality.

[0004] However, the following defects still exist:

[0005] (1) It has limitations in adaptability to terrain and environment, and is not suitable for complex forest scenes. In steep slope areas, the equipment is prone to slipping or tilting, which leads to deviation of the land preparation range, making it difficult to control accurately and increasing the safety risks for operators. In addition, it lacks anti-rust and anti-corrosion design, and long-term use is prone to component jamming.

[0006] (2) The soil pretreatment function is relatively simple and cannot screen and separate impurities such as stones and tree roots in the soil, which can easily lead to the obstruction of crop roots during subsequent planting, requiring additional manual cleaning and increasing operating costs; in addition, it can only complete basic land preparation and cannot simultaneously achieve soil improvement, requiring separate fertility enhancement operations to reduce overall planting efficiency.

[0007] Therefore, a land preparation device for understory planting is proposed. Utility Model Content

[0008] The purpose of this utility model is to address the existing problems.

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0010] The present invention is as follows: a forest underplanting land preparation device, comprising a device body, a connecting ring being fitted onto the outer ring surface of the device body, a connecting frame being fixedly connected to one side of the connecting ring, and a protective shell being inserted into the inner ring surface of the connecting frame.

[0011] A connecting block is fixedly connected to the inner ring surface of the protective shell, a motor is fixedly connected to one side of the connecting block, and a leveling roller is fixedly sleeved on the top of the output shaft of the motor.

[0012] A fixing ring is fixedly connected to the outer ring surface of the main body of the device, a limiting ring is fixedly connected to the upper surface of the main body of the device, an adjusting ring is fixedly connected to the upper surface of the sleeve ring, a fixing block is fixedly connected to one side of the adjusting ring, a nut is fixedly connected to one side of the fixing block, and a threaded rod is inserted into the inner ring surface of the nut for limiting.

[0013] As a preferred technical solution of this utility model, the inner ring surface of the sleeve ring is provided with an insertion opening, and the size of the insertion opening and the device body are matched.

[0014] As a preferred technical solution of this utility model, the outer ring surface of the leveling roller is fixedly connected with a leveling rod, and the number of leveling rods is multiple.

[0015] As a preferred technical solution of this utility model, the motor is connected to the protective shell through a connecting block, and the connecting block is symmetrically arranged vertically with the horizontal dividing line of the motor as the axis of symmetry.

[0016] As a preferred technical solution of this utility model, the nut is connected between a fixing block and an adjusting ring, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0017] As a preferred technical solution of this utility model, an operating handle is fixedly connected to one side of the fixed ring, and there are multiple operating handles arranged around the fixed ring as the center point.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Through the limiting sleeve structure between the sleeve ring and the main body of the device, and in conjunction with the adjustment assembly consisting of the adjusting ring, fixing block, nut and threaded rod, the position and angle of the land preparation roller can be flexibly adjusted. It can accurately control the land preparation range according to the different tree spacing, terrain undulations and crop row spacing requirements under the forest, and avoid damage to the tree root system. At the same time, the multiple operating handles set around the fixing ring are convenient for single or multiple people to operate in a coordinated manner, reducing the difficulty of operation in complex forest environments and greatly improving the flexibility and efficiency of land preparation operations.

[0020] 2. Multiple soil-clearing rods, fixedly connected to the outer ring of the soil-clearing roller, can uniformly break up and loosen the understory soil under the drive of a motor, avoiding local soil compaction and creating a loose soil environment for crop growth. The motor is fixed inside the protective shell by symmetrically arranged connecting blocks, which not only reduces the transmission of vibration during motor operation and ensures the overall stability of the equipment, but also isolates the motor from the entanglement or collision of understory branches and weeds, extending the service life of the equipment. At the same time, it ensures that the soil-clearing operation can be carried out continuously and stably, providing a reliable soil pretreatment guarantee for understory planting.

[0030] Please see Figure 1-4 The present invention provides a technical solution: a forest underplanting land preparation device, including a device body 1, a sleeve ring 2 that is limited and sleeved on the outer ring surface of the device body 1, a connecting frame 3 that is fixedly connected to one side of the sleeve ring 2, a protective shell 4 that is limited and inserted into the inner ring surface of the connecting frame 3, and a connecting block 14 that is fixedly connected to the inner ring surface of the protective shell 4.

[0031] In this embodiment, the inner ring surface of the sleeve ring 2 is provided with an insertion opening 16, and the size of the insertion opening 16 and the device body 1 are matched. The outer ring surface of the leveling roller 5 is fixedly connected with a leveling rod 6, and there are multiple leveling rods 6.

[0032] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a motor 15 is fixedly connected to one side of the connecting block 14, a leveling roller 5 is fixedly sleeved at the top of the output shaft of the motor 15, and a fixing ring 7 is fixedly connected to the outer ring surface of the device body 1.

[0033] In this embodiment, the motor 15 is connected to the protective shell 4 via the connecting block 14, and the connecting block 14 is symmetrically arranged vertically with the horizontal dividing line of the motor 15 as the axis of symmetry. The nut 12 is connected to the adjusting ring 10 via the fixing block 11, and the fixing block 11 is symmetrically arranged with the vertical center line of the nut 12 as the axis of symmetry.

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting ring 9 is fixedly connected to the upper surface of the main body 1 of the device, an adjusting ring 10 is fixedly connected to the upper surface of the sleeve ring 2, a fixing block 11 is fixedly connected to one side of the adjusting ring 10, a nut 12 is fixedly connected to one side of the fixing block 11, and a threaded rod 13 is inserted into the inner ring surface of the nut 12 for limiting.

[0035] In this embodiment, an operating handle 8 is fixedly connected to one side of the fixing ring 7, and there are multiple operating handles 8 arranged around the fixing ring 7 as the center point.

[0036] Specifically, when using this understory planting and land preparation device: First, the protective shell 4 is inserted into the inner ring surface of the connecting frame 3 through the inner ring adapter structure to ensure a stable connection between the protective shell 4 and the connecting frame 3; then, the sleeve ring 2 on the outer ring surface of the device body 1 is confirmed to be in a limited sleeve position through the inner ring insertion opening 16, ensuring that the sleeve ring 2 can move stably along the outer ring of the device body 1, laying the foundation for subsequent adjustments. The operator holds the multiple operating handles 8 arranged around one side of the fixing ring 7 and rotates the adjusting ring 10 to move the sleeve ring 2 along the outer ring of the device body 1, adjusting the lateral position of the connecting frame 3 and the protective shell 4; after the position is initially determined, the threaded rod 13 is rotated, and the cooperation of the nut 12 and the fixing block 11 is used to lock the adjusting ring 10 and the limiting ring 9 on the upper surface of the device body 1, accurately locking the working angle and range of the land preparation roller 5 to avoid damaging the roots of the understory trees. The system starts by activating the motor 15, which is fixed to the inner ring of the protective shell 4 via the connecting block 14. The output shaft of the motor 15 drives the tiling roller 5, which is fixedly sleeved at the top, to rotate at high speed. Multiple tiling rods 6 on the outer surface of the tiling roller 5 rotate with the roller, uniformly breaking and loosening the soil under the forest. At the same time, the protective shell 4 isolates the motor 15 from the entanglement or collision of branches, leaves and weeds under the forest, while the connecting block 14 reduces the vibration transmission of the motor 15 during operation, ensuring the overall stability of the equipment. During the operation, the operator pushes the main body 1 of the device along the preset planting row by operating the handle 8, so that the tiling roller 5 continuously covers the area to be tiled. If it is necessary to adjust the row spacing, the threaded rod 13 can be rotated in the opposite direction to loosen the adjusting ring 10, and the steps can be repeated to readjust the tiling position. After the operation is completed, the motor 15 is turned off, the integrity of each structure is checked, and then the equipment is transferred to the storage area to complete one forest tiling operation.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
