Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, specifically a self-propelled, range-extended, reciprocating cutter with adjustable blade width for tea garden side pruning. Background Technology

[0002] With the continuous expansion of tea plantation area in my country, the demand for mechanized management of tea gardens is becoming increasingly urgent. Statistics show that the tea plantation area increased from 35.51 million mu in 2013 to 51.45 million mu in 2023, mainly concentrated in hilly areas. This terrain is characterized by uneven topography, small and scattered plots, making traditional manual pruning inefficient and leading to rising labor costs. Mechanized pruning can not only improve operational efficiency and reduce labor intensity, but also enable precise operations, improve resource utilization efficiency, reduce waste and pollution, ensure the nutrient needs of tea trees, complete large-scale harvesting in a timely manner, guarantee tea quality, and enhance the economic benefits and market competitiveness of tea gardens.

[0003] Currently, some progress has been made in the research of tea tree pruning machines both domestically and internationally, but existing equipment still has shortcomings in terms of adaptability and efficiency. Domestic hand-held tea tree pruning machines, such as the KM3CJ-35 double-sided trimming machine and single-person handheld tea tree pruning machines, while capable of flexibly adjusting pruning width and angle to meet different pruning needs, still have limitations in large-scale and complex hilly tea gardens. Foreign self-propelled tea tree pruning machines, such as those produced by ARS (Japan) and STIHL (Germany), while highly automated, lack adaptability to hilly areas in my country and are mostly used in flat tea gardens. Therefore, designing a high-efficiency, highly adaptable tea garden side-pruning machine tailored to the specific needs of hilly tea gardens is of significant practical importance, contributing to the modernization of the tea industry in hilly areas and enhancing the international competitiveness of my country's tea industry. It can also be used for various operations such as hedge side-pruning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a self-propelled, extended-range, reciprocating cutter with adjustable blade width for tea garden side pruning, addressing the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A self-propelled, range-extended, reciprocating, width-adjustable side-pruning machine for tea gardens includes a tracked universal chassis, pruning components, and a width-adjusting mechanism. The pruning components, width-adjusting mechanism, and diesel engine are all mounted on the tracked universal chassis. The tracked universal chassis drives the pruning machine forward along the ground. The pruning components are used to prune tea bushes. The pruning components consist of two sets, arranged left and right on the width-adjusting mechanism, for pruning tea bushes on the left and right sides respectively. The width-adjusting mechanism includes a slider connecting plate, a slide rail, a slider connecting rod, a slider connecting block, an electric push rod, and a working component base plate. The slider connecting block is located at the movable end of the electric push rod. The electric push rod is horizontally fixed on the base plate of the working component. The base plate of the working component is fixed on the tracked universal chassis. One end of the slider connecting rod is hinged to the slider connecting block, and the other end is hinged to the slider connecting plate. The slider connecting plate is fixedly connected to the slider on the slide rail. The slider connecting rod and the slider connecting plate form a sliding arm. There are two sets of sliding arms symmetrically arranged on the left and right sides of the electric push rod. A set of trimming components is fixed on the slider connecting plates of the two sets of sliding arms respectively. When the movable end of the electric push rod extends or retracts, it can push the two sliding arms to drive the two trimming components to move closer or further apart.

[0007] Furthermore, the universal tracked chassis includes tracks, a motor, a left drive wheel, a left track side plate, a right drive wheel, a right track side plate, a right driven wheel, a left driven wheel, a crossbeam square steel, and a working component support plate. The left driven wheel is fixed to the left track side plate via an axle and bearing, and the right driven wheel is fixed to the right track side plate via an axle and bearing. The tracks are fixed to the left drive wheel, right drive wheel, right driven wheel, and left driven wheel via grooves. The motor is fixed to the left track side plate and the right track side plate via bolts. The crossbeam square steel is fixed to the left track side plate and the right track side plate by welding. The motor is fixed relative to the left drive wheel and the right drive wheel via a key.

[0008] Furthermore, the trimming component includes a reciprocating cutter, a cutter motor, a cutter handle fixing plate, a sleeve fixing plate, and a sleeve. The cutter handle fixing plate and the sleeve fixing plate are welded to the slider connecting plate. The reciprocating cutter is connected to the cutter motor through the sleeve and the shaft. The cutter handle fixing plate is fixed to the reciprocating cutter by two bolts, and the sleeve fixing plate is fixed to the sleeve by two bolts.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] The advantages of this invention are that the machine's overall width is ≤600mm, allowing it to move flexibly between tea ridges in tea gardens without damaging the tea trees. During operation, the engine drives a generator to power the tracked chassis and charge the battery, ensuring continuous pruning operations. The width adjustment device, via an electric push rod transmission system, allows for flexible adjustment of the cutter width within 50-70cm, adjusting the working range of the cutter. This is further secured by a slider and electric push rod, meeting the pruning needs of different ridge widths. Simultaneously, the reciprocating cutter itself can have its angle adjusted via a screw, effectively pruning branches of different diameters. It meets the requirements for shaping pruning of young tea trees and light pruning of mature tea trees. This pruning machine can significantly improve the mechanization level of pruning in hilly tea gardens, reduce manual labor intensity, and improve tea production efficiency and quality, making it widely applicable.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
