Description

Trim equipment in a kind of hanging-connecting tea place side

Technical field

A kind of pruning tool is the utility model is related to, especially a kind of hanging-connecting tea place side trimming equipment, belong to agricultural Field of mechanical technique.

Background technology

According to the applicant understood, for a long time, the trimming of tea place side fixes the reciprocal of support using soft axle transmission, both-end Formula razor construction, it is equidistant that it cuts cutter tooth.In practice, there are the following problems for this existing trimming equipment：

1）Both ends support fixed structure is when needing to adjust operation height, since blade both ends fixed module can free skating It is dynamic, therefore it is difficult to ensure that blade in same plane, easily deviates, phenomena such as excessive wear, fracture easily occurs in high-speed job； And tea tree near end branch diameter is thicker, the fixed structure of equipment lower end be easy to cause tea tree branch blocking and damages tea tree； Especially tea tree side trimming is different from the fluffy trimming of tea, because of branch thickness inequality, during the vertical operation of blade in branch extruding force, cut Shear force and equipment move ahead under the effect such as thrust, flexural deformation phenomenon easily occur, cause excessive wear, are even broken；

2）As the increase of flexible axle length, power loss constantly increase in driven by quill shaft transmission process, especially shearing During run into stone, iron wire when hard foreign matter, unexpected rigid shock easily cause flexible axle damage；

3）Branch diameter change is not suitable with Deng tooth pitch, often swaging clamp phenomenon occurs because low section of branch of tea tree is excessively thick, not only The pruning efficiency is influenced, also makes tool damage rate higher.

Although the Chinese patent of Patent No. ZL201520478223.9 has carried out prior art beneficial improvement, simultaneously The above problem is not properly settled.

The content of the invention

The purpose of this utility model is that：The problem existing in the prior art for more than, propose one kind can it is convenient into While row working depth adjusts, prevent cutter distortion fracture, effectively avoid the hanging-connecting tea place side trimmer of swaging clamp phenomenon Tool, so as to ensure operating efficiency, greatly prolongs service life.

In order to reach object above, the basic technical scheme of the utility model hanging-connecting tea place side trimming equipment is：Bag Include the vertical electric pushrod mechanism being connected by upper and lower mounting fixing piece with traction frame, the movement of the electric pushrod mechanism Block is connected with outer cover shell component；The upper end of the outer cover shell component and the mounting base of trunnion axis hydraulic motor are connected, and away from extension Vertical tool magazine is fixed in the side for connecing fixing piece；The output shaft of the hydraulic motor has two eccentric wheels that angular position staggers, institute State tool magazine and shaving shape or so cutting blade and form vertical prismatic pair, two eccentric wheel is cut by left linkages and left and right respectively The upper end of cutting blade hingedly forms eccentric wheel sliding block mechanism.

The utility model not only instead of original both-end with single-ended support driving blade mechanism and fix support, so that from knot Phenomena such as cutter result in excessive wear, fracture in high-speed job because of installation error is avoided on structure, while avoids equipment The fixed structure of lower end be easy to cause tea tree branch blocking and damages tea tree, and the single-ended supporting structure and electric pushrod are reasonable With reference to that has properly settled working depth facilitates regulation problem；In addition, the utility model uses direct connection hydraulic-driven not only efficiency Height, and by the overload protection characteristics of hydraulic pressure rigid shock can be avoided to cause breaks down.

The utility model further improves：The cutter tooth of the left and right cutting blade is at least divided into that tooth pitch is smaller, tooth is high Higher epimere and tooth pitch is larger, the high relatively low hypomere of tooth.The cutting blade of this non-homogeneous tooth is adapted to lower tea tree branch The thick actual condition of bar, effectively avoids the occurrence of swaging clamp phenomenon, improves shear efficiency, reduce further the spoilage of blade.

Embodiment

Embodiment one

As shown in Figures 1 to 5, when design, fully takes into account the hanging-connecting tea place side trimming equipment of the present embodiment：Tea place Planted according to specification 1.5m line-spacing duplicate rows bar into age tea tree, generally set high 90cm-120cm, a diameter of 3- of the following branches of ground 40cm 10cm or so, 0.3-3cm a diameter of higher than the branch of 40cm, prior art are not suitable with branch diameter change, often because of tea tree Upper 40cm sections of branch is excessively thick and swaging clamp phenomenon occurs, not only influences the pruning efficiency, also makes tool damage rate higher.

The trimming equipment of the present embodiment includes vertical electric pushrod mechanism 5, on the guide rod 5-2 of the electric pushrod mechanism 5 Lower end is connected by upper mounting fixing piece 7 and lower mounting fixing piece 7 ' with traction frame respectively, the shifting in the electric pushrod mechanism 5 Motion block 5-1 is connected with outer cover shell component 4.Outer cover shell component 4 is surrounded by left and right case, and the upper end of outer cover shell component 4 passes through arc Plate 6 and the mounting base of trunnion axis hydraulic motor 1 are connected, and the side away from mounting fixing piece 7 is fixed to form with cutter 3-2 and moved Move secondary vertical tool magazine 3-1.The output shaft of hydraulic motor 1 and the prior art are similar, have two eccentric wheels that angular position staggers, Tool magazine 3-1 and shaving shape or so cutting blade 3-2 form vertical prismatic pair, and two eccentric wheels are cut by left linkages and left and right respectively The upper end of cutting blade hingedly forms eccentric wheel sliding block mechanism.The cutter tooth of left and right cutting blade 3-2 is divided into that tooth pitch is smaller, tooth is high Epimere and tooth pitch is larger, the high relatively low hypomere of tooth, a height of 21mm of epimere tooth, the tooth pitch 35mm of the present embodiment cutting blade, The a height of 16mm of hypomere 40cm teeth, tooth pitch 40mm, the measure that this adaptability reduces tooth height, increase tooth pitch can improve shearing energy Power, because being planted according to 1.5m line-spacing duplicate rows bar into age tea tree, generally sets high 90cm-120cm, 40cm following branches in ground are a diameter of 3-10cm or so, 0.3-3cm a diameter of higher than the branch of 40cm.

Experiment shows that the present embodiment utility model does not avoid cutter in high-speed job because installation error is led from structure Phenomena such as having caused excessive wear, fracture, at the same tea tree branch blocking caused by avoiding equipment lower end and damage tea tree, work is high Degree can easily step-less adjustment, transmission efficiency be aobvious with the overload protection characteristics for avoiding rigid shock from causing breaks down Writing reduces the spoilage of blade, and tea tree both sides can be trimmed at the same time, and can be adjusted at the same time by adjusting setting angle Cutting range, width and both sides cut-back angles are saved, it is easy to operate, it is easily manipulated, degree of regulation is high.
