Description

Technical Field

[0001] This utility model relates to the field of grassland ecological restoration equipment technology, and in particular to a starting device for ecological restoration of alpine meadows. Background Technology

[0002] In the ecological restoration of alpine meadows, a crucial step is the complete excavation and transplantation of native turf, including the roots. The quality of this work directly determines the meadow's recovery rate. Currently, this work is mostly carried out using traditional excavators or tillers, but these general-purpose machines have revealed significant shortcomings when applied to this refined operation.

[0003] Traditional excavators and tillers were not designed for precise turf cutting. Their operation is often a crude, "one-cut" approach, making it difficult to accurately control the cutting depth. If the cut is too shallow, it will not include the complete root system (usually 15-30cm deep), damaging the turf structure and making it prone to crumbling during excavation and transportation, resulting in a low yield of finished turf. If the cut is too deep, it will remove too much subsoil, increasing equipment load and transportation costs, and also causing unnecessary disturbance to the original soil structure.

[0004] The root cause of this inaccurate control over the working thickness lies in the lack of a stable and reliable height adjustment and locking mechanism in existing equipment, capable of adapting to the rugged terrain and continuous operational vibrations of the plateau. In bumpy and vibrating working environments, even equipment with adjustment functions is prone to loosening or displacement of its locking devices, causing the set working depth to constantly change during actual operation. This unstable working condition not only severely affects the quality and integrity of turf excavation but also significantly reduces overall operational efficiency, contradicting the goals of high efficiency, low disturbance, and high survival rate pursued in plateau ecological restoration.

[0005] Therefore, this utility model proposes a starting device for ecological restoration of alpine meadows to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a lifting device for the ecological restoration of alpine meadows, aiming to improve the problems of unreliable locking of the height adjustment mechanism under vibration conditions, easy accidental changes, and inconvenient adjustment and locking operations in the existing lifting devices for the ecological restoration of alpine meadows.

[0007] To achieve the above objectives, this utility model provides a lifting device for ecological restoration of alpine meadows, comprising: a lifting machine and a support assembly fixedly connected to the lifting machine.

[0008] The support assembly includes a support block and a baffle. The support block has a threaded post with internal threads. A handle is fixedly connected to the top of the threaded post, and a support wheel is rotatably connected to the bottom of the threaded post.

[0009] The lower outer periphery of the handle has multiple snap-fit ​​grooves.

[0010] Furthermore, the baffle, the limiting block, and the support block are slidably disposed within the support block via the baffle. The baffle and the limiting block are integrally connected. A spring is provided between the limiting block and the inner wall of the support block. The baffle is configured such that, under the elastic force of the spring, one end of it extends into and is locked into one of the locking grooves.

[0011] Preferably, the support block has a guide hole, and the shaft of the support wheel is fixedly connected to a guide post, which is slidably fitted into the guide hole.

[0012] Preferably, it also includes a cutting component, which is fixedly connected to the front end of the loading machine.

[0013] Preferably, the cutting assembly includes a blade that is detachably fixed to the loading machine by bolts.

[0014] Preferably, both the loading machine and the blade are provided with slots for the bolts to pass through.

[0015] Preferably, the cutting assembly further includes a first wedge-shaped washer and a second wedge-shaped washer fitted onto the bolt.

[0016] Preferably, the surfaces of the first wedge-shaped gasket and the second wedge-shaped gasket that are in contact with each other are formed with interlocking wedge-shaped teeth.

[0017] Preferably, at least one of the first wedge-shaped gasket and the second wedge-shaped gasket has radial teeth formed on its surface opposite to the other gasket.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting a simple and reliable height adjustment and locking mechanism consisting of a threaded column, a handle, a snap-fit ​​groove and a baffle, the problem of difficulty in accurately controlling the thickness and easy cutting of roots leading to turf breakage during traditional excavator or tiller operation is solved. It achieves the effect of setting and maintaining the cutting depth according to the meadow root layer, ensuring the integrity of the excavated turf block structure and high yield.

[0020] 2. This utility model solves the problem that the connecting bolts of the equipment are easy to loosen under high-intensity vibration, which leads to cutting interruption or poor effect by using double anti-loosening washers with wedge-shaped teeth and radial fine teeth to fix the cutting blade. It achieves the technical effect of ensuring the blade connection is stable even under severe vibration, realizing continuous and uniform cutting, and thus successfully separating the complete turf, which provides a guarantee for the high recovery rate of the meadow.

[0021] 3. This utility model solves the problem that when the support wheel is easily deflected or shaken when the height adjustment is made by opening a guide hole in the support block and fixing a guide column that slides with the guide hole on the rotating shaft of the support wheel. This results in an unstable adjustment process and affects the accuracy. It provides a stable guide for the lifting and lowering of the support wheel, prevents its rotation and deflection, and ensures a smooth, stable and accurate height adjustment process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-4This utility model provides a lifting device for alpine meadow ecological restoration, which aims to solve the problems of complex structure of the working height adjustment mechanism, insufficient locking reliability, and easy loosening of the connection of the cutting parts under severe vibration environment in existing alpine meadow restoration equipment, thereby affecting the stability and safety of operation.

[0030] Specifically, it includes a lifting machine 1 as the main load-bearing body, a support component 2 fixedly connected to the lifting machine 1, and a cutting component 3 fixedly connected to the front end of the lifting machine 1. The support component 2 is used to support the lifting machine 1 and realize the precise adjustment and stable locking of the overall working height. The cutting component 3 is used to cut the meadow during the movement of the equipment.

[0031] The support assembly 2 includes a support block 201 fixedly connected to the bottom of the lifting machine 1 by welding or bolting. The support block 201 has an internally threaded hole extending vertically. A threaded post 202 is threaded into the internally threaded hole. The upper end of the threaded post 202 protrudes from the top surface of the support block 201. The top end of the threaded post 202 is fixedly connected to a handle 203 for easy gripping and rotation by a key or integral molding. The bottom end of the threaded post 202 is rotatably connected to the axle of the support wheel 204 by a rolling bearing. This connection method allows the threaded post 202 to rotate within the support block 201 and move smoothly up and down along the axial direction when the handle 203 is turned, thereby driving the support wheel 204 to rise or fall, thus changing the ground clearance of the lifting machine 1.

[0032] To achieve quick and reliable locking after height adjustment, multiple locking grooves are uniformly machined along the circumferential direction on the lower outer periphery of the handle 203. These locking grooves can be V-shaped, U-shaped, or rectangular, providing multiple independent locking points. Simultaneously, a transverse sliding cavity is formed on the support block 201, and a baffle 206 is slidably disposed within this cavity. The baffle 206 is integrally connected to a limiting block 207, which is also accommodated within the cavity inside the support block 201. A spring 208, which is usually a compression spring, is provided between the walls to provide preload. In its natural state, the elastic force of the spring 208 continuously pushes the limiting block 207 and the baffle 206, so that one end of the baffle 206 extends into and is locked in a locking groove at the lower end of the handle 203. The end profile of the baffle 206 matches the profile of the locking groove to form a stable engagement, thereby circumferentially limiting the handle 203, preventing the handle 203 from rotating accidentally, and thus firmly fixing the position of the threaded post 202, ensuring the stability of the working height.

[0033] To further ensure the smoothness and stability of the support wheel 204 during lifting and lowering, and to prevent it from rotating along with the threaded column 202, a guide hole is provided in the support block 201 along a direction parallel to the axis of the threaded column 202. Correspondingly, a guide column 205 is firmly fixedly connected to the rotating shaft of the support wheel 204. The outer diameter of the guide column 205 and the inner diameter of the guide hole form a tight sliding fit. During height adjustment, when the threaded column 202 rotates and rises, the guide column 205 can only slide in a pure axial straight line under the constraint of the guide hole, thus forming an efficient anti-rotation guide mechanism. This ensures that the support wheel 204 always maintains the correct orientation and can effectively resist lateral impact forces from the ground, protecting the threaded pair structure.

[0034] To address the issue of loose connections in cutting components caused by strong vibrations during equipment operation on rough terrain, the cutting assembly 3 includes a blade 301. The blade 301 is detachably fixed to the front end of the loading machine 1 by bolts 302. To facilitate installation, positioning, and fine-tuning, both the loading machine 1 and the blade 301 are provided with slots 305 for the bolts 302 to pass through.

[0035] It also includes a first wedge-shaped washer 303 and a second wedge-shaped washer 304 fitted onto the shank of the bolt 302. These two washers are used in pairs. On the surfaces where the first wedge-shaped washer 303 and the second wedge-shaped washer 304 meet, interlocking wedge-shaped teeth are formed. The helix angle of these wedge-shaped teeth is specially designed to be greater than the helix angle of the bolt thread 302. When the bolt 302 is tightened and an axial clamping force is generated, if there is vibration or torque that causes the bolt to loosen, the wedge-shaped tooth surfaces of the first wedge-shaped washer 303 and the second wedge-shaped washer 304 will undergo slight relative slippage. Due to the design of the helix angle of the wedge-shaped teeth, the axial lifting tension generated by this slippage will be greater than the preload of the bolt thread that is reduced due to loosening, thereby forming a net increase in tensile stress inside the bolt, producing a strong wedge-shaped locking effect and effectively counteracting the loosening torque.

[0036] On the surface of at least one of the first wedge-shaped gasket 303 and the second wedge-shaped gasket 304 that faces away from the other gasket, i.e. the surface that contacts the lifting machine 1 and the blade 301, dense radial fine teeth are machined. When the bolt 302 is tightened, these radial fine teeth with higher hardness will be pressed into and embedded into the surface of the connected parts with lower hardness, forming a strong mechanical engagement, which greatly increases the static friction between the gasket and the connected parts, thereby completely preventing the gasket itself from rotating, ensuring that the only relative movement can only occur between the wedge-shaped tooth surfaces of the two gaskets. Through the synergistic effect of the internal self-locking of the wedge-shaped teeth and the external locking of the radial fine teeth, the blade 301 can maintain a stable connection even under the most severe working conditions.

[0037] Working Principle: Before operation, the cutting depth of the equipment needs to be set according to the root layer depth of the target meadow. During operation, the baffle 206 is pressed first. After being subjected to force, the baffle 206 slides inward against the elastic force of the spring 208, and its locking end disengages from the locking groove of the handle 203, releasing the lock on the handle 203. Then, the handle 203 can be rotated. The handle 203 drives the threaded column 202 to rotate in the support block 201 and rise and fall smoothly along the axial direction, thereby changing the relative position of the support wheel 204 and realizing the height adjustment of the entire lifting machine 1 and the front cutting component 3. When the predetermined working height is reached, the baffle 206 is released. Under the action of the spring 208, the baffle 206 automatically resets and re-locks into the nearest locking groove, firmly locking the handle 203, thereby ensuring that the cutting depth remains constant during operation.

[0038] After setup, the equipment starts and moves forward. The blade 301, fixed to the front end of the lifting machine 1, begins to cut the meadow. During the cutting process, the equipment generates strong vibrations. At this time, the first wedge-shaped washer 303 and the second wedge-shaped washer 304, which are used to fix the blade 301, begin to function. Their interlocking wedge-shaped teeth utilize the vibration energy to generate a reverse lifting tension, achieving reliable self-locking. At the same time, the radial fine teeth on their backs also firmly engage with the surface of the connecting parts, preventing any loosening of the bolt 302 due to vibration, ensuring the continuity and stability of the cutting operation, and thus enabling the even and neat separation of turf with intact roots from the soil. In addition, the steel plate of the lifting machine 1 has weight-reducing holes, which effectively reduce the weight of the equipment and improve its passability and maneuverability on the soft ground of the plateau.
