Description

Technical Field

[0001] This utility model relates to the technical field of tea picking and pruning machines, and in particular to an angle-adjustable tea picking and pruning machine. Background Technology

[0002] Tea pruning machines are essential equipment for mechanized harvesting and canopy shaping in tea garden management. In actual operation, due to the undulating terrain and differences in tea varieties, the tea canopy layer often exhibits an irregular spatial distribution: on the one hand, there is a difference in elevation between the planting areas on both sides of the tea trees, which means that the left and right blades need to adapt to different working heights when the machine moves; on the other hand, the tea trees themselves grow at different heights, requiring the pruning blades to have dynamic vertical adjustment capabilities.

[0003] Currently, most mainstream tea-picking and pruning machines use a split-type bolt-fastening structure to adjust the blade height. This solution has a significant drawback:

[0004] 1. Low adjustment efficiency: Operators need to individually tighten or loosen the fixing bolts of the cutter, and the machine needs to be stopped during the adjustment process;

[0005] 2. Insufficient positioning accuracy: Bolt tightening is prone to loosening due to vibration, which can cause tool displacement during operation and result in an uneven tea crown trimming surface;

[0006] 3. Functional limitations: It cannot achieve overall posture adjustment of the tool holder, making it difficult to adapt to the inclined surface of tea crowns in sloping tea gardens. Utility Model Content

[0007] This utility model addresses the shortcomings of existing technologies by providing a tea-picking and pruning machine that achieves overall lifting and tilting adjustment of the cutter through a dual-sided independent lead screw mechanism.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an angle-adjustable tea-picking and pruning machine, comprising...

[0009] The chassis is used to mount the front and rear wheels;

[0010] A lifting frame, with its lifting mechanism mounted on a base and equipped with trimming blades; and

[0011] The symmetrically arranged adjustment components are located between the base frame and the lifting frame to realize the vertical lifting of the lifting frame relative to the base frame, thereby realizing the lifting adjustment of the trimming blade relative to the base frame.

[0012] In the above scheme, preferably, the adjusting component includes an adjusting screw and an adjusting nut that cooperates with it;

[0013] The adjusting screw is rotatably mounted on the lifting frame, and the adjusting bolt is fixed to the base frame.

[0014] In the above scheme, preferably, the base frame is provided with a plurality of positioning tubes, and the lifting frame is provided with a lifting tube that is slidably sleeved with the positioning tubes;

[0015] The adjusting nut is located on any of the positioning tubes, and the adjusting screw is located on the lifting tube that cooperates with the positioning tube.

[0016] In the above scheme, preferably, an adjustment gap is provided between the inner wall of the lifting tube and the outer wall of the positioning tube.

[0017] In the above scheme, preferably, the adjusting screw rotates through the lifting tube and then cooperates with the adjusting nut, and the adjusting nut is fixed at the upper end of the positioning tube.

[0018] In the above scheme, preferably, a handle is fixedly provided at the upper end of the adjusting screw.

[0019] In the above scheme, preferably, the adjusting screw is provided with a limiting plate, the upper end of the lifting tube is provided with a fixing plate, and the fixing plate is provided with a rotating hole that cooperates with the adjusting screw;

[0020] The adjusting screw is engaged with the rotating hole via a limiting plate and a handle.

[0021] In the above scheme, preferably, the adjusting screw is a lead screw and the adjusting nut is a ball nut.

[0022] In the above scheme, preferably, the trimming blade is fixed on the lifting pipes on both sides.

[0023] In the above scheme, preferably, the handle includes a rotating arm and a gripping handle disposed on the rotating arm, one end of the rotating arm is fixedly connected to the adjusting screw, and the other end is provided with a gripping handle;

[0024] The rotating arm is equipped with a pin that cooperates with the grip handle.

[0025] The beneficial effects of this utility model are: This utility model drives the overall lifting of the lifting frame through the symmetrically arranged screw and nut adjustment components, which subverts the traditional split bolt adjustment mode, greatly shortens the height adjustment time, and does not require stopping the machine during adjustment, thus greatly improving the efficiency of the tea picking and pruning machine.

[0026] Meanwhile, by utilizing the adjustment gap design between the lifting tube and the positioning tube, and in conjunction with the handle mechanism with independent control on both sides, the tilt angle of the pruning blade can be dynamically adjusted, effectively solving the problem of fitting the pruning of the inclined surface of the tea crown in sloping tea gardens;

[0027] In addition, the self-locking transmission using a trapezoidal lead screw and ball nut maintains high positioning accuracy in vibration environments. Meanwhile, the anti-detachment structure of the limit plate and the fixed plate ensures the long-term operational stability of the mechanism, achieving the combined effects of efficient operation, precise adaptation to complex terrain, and reduced operational intensity.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-5 .

[0034] An angle-adjustable tea-picking and pruning machine includes a base frame 1, a lifting frame 2, and adjustment components symmetrically arranged on both sides.

[0035] The base frame 1 is equipped with a front wheel 101 and a rear wheel 102, which are symmetrically arranged on both sides of the base frame 1. The lifting frame 2 is movably mounted on the base frame 1 and is equipped with a pruning blade 201. The pruning blade 201 is mounted at one end of the base frame 1 in the direction of travel. Preferably, the pruning blade 201 can be a pruning blade of a pruning machine or a pruning blade of a tea picking machine. The blades can be fixed on the lifting frame 2 by mounting plates with the same spacing to achieve mutual replacement.

[0036] The adjustment assembly is located between the base frame 1 and the lifting frame 2. Adjustment of the adjustment assembly drives the lifting frame 2 to move vertically relative to the base frame 1. Specifically, the adjustment assembly includes an adjustment screw 301 and an adjustment nut 302 threadedly engaged with it. The adjustment screw 301 is rotatably mounted on the lifting frame 2, and the adjustment nut 302 is fixed to the base frame 1. The adjustment screw 301 and the lifting frame 2 are rotatably engaged. When the adjustment screw 301 rotates, it can move vertically relative to the adjustment nut 302, thereby driving the lifting frame 2, which is engaged thereon, to move vertically.

[0037] Furthermore, the base frame 1 is provided with several vertical positioning tubes 303, and the lifting frame 2 is provided with lifting tubes 304 that are slidably sleeved with the positioning tubes 303. The adjusting nut 302 is fixed to the upper end of one of the positioning tubes 303 by welding. The adjusting screw 301 is installed on the corresponding lifting tube 304, and the upper end of the adjusting screw 301 is rotatably locked to the upper end of the lifting tube 304, while the lower end is threadedly engaged with the adjusting nut 302. The lower end of the lifting tube 304 is slidably sleeved on the upper end of the positioning tube 303 to achieve mutual sliding between the two, thereby realizing the vertical sliding of the lifting frame 2 relative to the base frame 1.

[0038] An adjustment gap 305 is provided between the inner wall of the lifting tube 304 and the outer wall of the positioning tube 303, allowing the lifting tube 304 to deflect slightly during the adjustment process.

[0039] The adjusting screw 301 passes through the fixed plate 308 at the upper end of the lifting tube 304 and forms a rotating pair with the fixed plate 308 through the rotating hole 309. The adjusting screw 301 is provided with a limiting plate 307, which is set below the fixed plate 308 and cooperates with the fixed plate 308 to prevent the screw from coming out. The adjusting screw 301 is fixed with a handle 306 at the upper end of the fixed plate 308. The adjusting screw 301 is rotated and locked on the fixed plate 308 through the cooperation of the handle 306 and the fiberboard 307. After the adjusting screw 301 passes downward through the fixed plate 308, the lower end of it is threadedly engaged with the adjusting nut 302 on the positioning tube 303.

[0040] For ease of operation, the handle 306 includes a rotating arm 4 and a grip 5. One end of the rotating arm 4 is fixedly connected to the adjusting screw 301, and the other end is fitted with the grip 5 via a pin.

[0041] The adjusting screw 301 is a trapezoidal lead screw, and the adjusting nut 302 is a ball nut, which has both self-locking and low-friction characteristics; the trimming blade 201 is directly fixed on the lifting tubes 304 on both sides to ensure accurate transmission of lifting action.

[0042] In use, the adjusting screw 301 is driven to rotate by rotating the handles 306 on both sides. Since the adjusting nut 302 is fixed to the positioning tube 303, the rotation of the screw drives the lifting tube 304 to move axially along the positioning tube 303. When both sides rotate synchronously, the lifting frame 2 is raised and lowered as a whole; when the handle 306 is rotated on one side (for example, rotating the left handle counterclockwise), the lifting tube 304 on that side rises, so that the pruning blade 201 forms an inclined working angle to adapt to the different slope heights on both sides of the tea tree.

[0043] The adjustable gap 305 (0.5-2mm) allows the lifting tube 304 to slide smoothly with the positioning tube 303 when tilted. The ball nut and trapezoidal screw work together to ensure that the lifting and positioning accuracy is controlled within ±2mm and there is no displacement under operational vibration.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
