Chinese patent: a kind of on-vehicle hedge clipping machine; Application number: CN201010195513.4, the applying date: 2010.06.08, publication number: CN101849481A; Open day: 2010.10.06; The applicant: Chang An University, the address: No. 33, stage casing, South 2nd Ring Road, Xian City, Shanxi Province, the inventor: Zhao realizes; Luo Xiaohui; Zhang Xianlei; Liang Fengkai; Meng Qingcun; Miao Wenying; Feng Zhongxu; Yao Yunshi, summary: disclose a kind of on-vehicle hedge clipping machine, comprised carrying vehicle and be installed in the hedge trimming equipment on the carrying vehicle; Cutterhead frame, the level that hedge trimming equipment comprises can be at the rotary table of 360 ° of rotations on the horizontal plane, can carry out elastic and the telescopic arm that moves up and down simultaneously, be fixedly mounted on the telescopic arm leading section be installed in a plurality of rotary cutters, the cutter drives mechanism that rotary cutter is driven below the cutterhead frame, drive the cutterhead frame carry out around cutterhead upset driving mechanism, base drive unit, telescopic arm drive unit and the control system of rotary movement.Trimmer is simple in structure, easy to operate, automaticity is high, operating efficiency is high, it is fast and job area wide, prune that quality is high, job safety to prune the attitude conversion speed, can effectively overcome a high position that existing hedgeclipper exists and prune the defective such as need respectively two cover independent agencies, complicated operation, production cost is high, automaticity is low, job area is little of beating the grass with low level.
The inventor finds, more than the pruning executing agency that adopts of disclosed document have following problem: 1, the power source of executing agency adopts the power frequency threephase asynchronous machine, and maximum speed is merely 3000 rev/mins in theory; 2, the restriction of motor current collector insulating properties can't be used under the moist in the open air operating environment; 3, the cutting blade shape of executing agency adopts the rectangle structure blade; Practice effect from both combinations; Far can not reach desirable effect to hedge trimming, it is low to prune efficient, follows comparatively thick branch to cut off simultaneously and the phenomenon of the broken head of branch; 4, a plurality of cutting blades of executing agency adopt yi word pattern to arrange, owing to have the gap between the adjacent blade, cause the generation of pruning the dead angle.Therefore, extremely urgent as the research and development of the novel hedge trimming mechanism of such device core.
Summary of the invention
The purpose of the utility model promptly is to provide a kind of and can solves above-mentioned deficiency, and hedgerow maintenance simple in structure, that efficient is high is pruned mechanism at a high speed with staggered cutter battle array.
For realizing above-mentioned purpose, the maintenance of the utility model hedgerow is pruned mechanism at a high speed with staggered cutter battle array and is comprised circular saw bit cutter, hydraulic system and protection outer cover, and be characterized in: described hydraulic system comprises hydraulic motor, hydraulic cylinder, synchronized splitter motor and valve body; Pruning executing agency adopts several to prune the unit; Each hydraulic motor is formed one with each circular saw bit cutter respectively and is pruned the unit; It is isosceles triangle alternating expression arrayed structure in circumference arrangement radially that described several are pruned the unit; The circular saw bit cutter that is used to prune execution is installed on the hydraulic motor output shaft by shaft coupling and directly drives, and each hydraulic motor is all concentrated and by the synchronized splitter motor power is provided, and sleeve mechanism also is equipped with the protection outer cover outward.
Above-described valve body comprises unidirectional adjustable throttling, reversal valve and check valve; Hydraulic oil commutates through reversal valve through check valve; And carry out throttling by unidirectional adjustable throttling, and get into the synchronized splitter motor, concentrate hydraulic motor and hydraulic cylinder are driven and control.
It is 3～11 that above-described several are pruned the unit.
Above-described hydraulic motor adopts the little displacement hydraulic motor of high rotating speed.
Compare with prior art, the beneficial effect that the maintenance of this hedgerow is pruned mechanism at a high speed with staggered cutter battle array is:
The utility model adopts the little displacement hydraulic motor of high rotating speed as drive source; Through the direct driver plate sawtooth pattern of shaft coupling blade; Output speed is greater than 4000 rev/mins; From the practice effect analysis that both combine, prune efficient and improve a lot, can well prune diameter at the thick branch bar below 30 millimeters.A plurality of cutting blades of executing agency adopt isosceles triangle alternating expression arrayed, do not have the gap between the blade, make that pruning operation does not have the dead angle.Adopt the synchronized splitter motor to concentrate each hydraulic motor is carried out power supply; Promptly avoid fully under the simply shunting situation owing to the serious uneven rotating speed that causes of each cutting blade cutter load is asynchronous; The hydraulic control structure of the complicacy of also giving up a plurality of synchronous valve stacks and forming makes and makes and all greatly decline of maintenance cost.Lace and trees neat appearance are isolated in greening after the pruning.Also can use in the moist in the open air environment of the little displacement hydraulic motor of high speed that this mechanism adopts.
