Abstract
The utility model relates to a hydraulic tree pruner. The utility model comprises a long rod, a pair of scissors and a universal joint which can adjust the pair of scissors to rotate to random directions, wherein one end of the universal joint is fixed on the head end of the long rod. The utility model is characterized in that a hydraulic device is arranged on the long rod and connected with two handles of the pair of the scissors; the hydraulic device is manipulated to realize the push and the draw of the connected handles of the pair of the scissors so as to realize the open and the close of an opening of the pair of the scissors and complete the pruning of tree branches or the shearing picking of fruit. The utility model has the advantages of simple structure, large shearing force, convenience in use and labour saving.
Description
Technical field:
The utility model belongs to the branch pruning instrument, is used to prune higher branch or cuts and pluck higher fruit.
Background technology:
The present averruncator that uses, normally, an end of stock or telescopic stock has a scissors, a handle of scissors is fixed on the stock, another handle splicing, and rope hangs down and is controlled by the user, between two handles of scissors spring is arranged, make the scissors mouth of scissors be in open state; When under the user during pulling cord, scissors mouth closure is cut the branch that need cut, and when unclamping rope, the scissors mouth opens under the effect of spring, carries out cut operator next time.Though the structure of this averruncator is simple, shearing force is less when having pruning, and slightly slightly the branch of any is just cut continuous defective.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of rapid operation, fluid pressure type averruncator that shearing force is big.
The technical solution of the utility model is, a kind of fluid pressure type averruncator, comprise stock, scissors and can regulate the universal joint that the scissors any direction rotates, one end of universal joint is fixed in the head end of stock, it is characterized in that, hydraulic means is arranged on the stock, two handles of hydraulic means and scissors are connected, operating hydraulically operated device, the edge of a knife of scissors (70) can be in closed or open position, finish the pruning or the cutting of fruit of branch are plucked.
The utility model has the advantages that simple in structure, shearing force is big, convenient during use, laborsaving, only need very little strength, just can finish the pruning of branch, fruit cut, easy especially, without lifting an eyebrow.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Hydraulic means of the present utility model comprises initiatively hydraulic cylinder 40, driven hydraulic cylinder 60 and connect the withstand voltage oil pipe 50 of oil circuit between them, and the handle 20 of operating hydraulically operated device, initiatively the cylinder body of hydraulic cylinder 40 is hinged with the cylinder frame 30 that is fixed in stock 10 tail ends, the piston rod 41 of the front end of handle 20 and active hydraulic cylinder 40 is hinged, the fulcrum 21 and the cylinder frame 30 of handle 20 are hinged, initiatively the oil nozzle 61 of the oil nozzle 43 of hydraulic cylinder 40 and driven hydraulic cylinder 60 is communicated with by withstand voltage oil pipe 50, the head end of the cylinder body of driven hydraulic cylinder 60 and universal joint 80 is hinged, the other end of universal joint 80 is fixed in the head end of stock 10, a handle of the piston rod 63 of driven hydraulic cylinder 60 and scissors 70 is hinged, another handle of scissors 70 and the cylinder body of driven hydraulic cylinder 60 are hinged; Between two handles of scissors 60, back-moving spring 71 is arranged.When holding handle 20 with a firm grip, the head end of handle 20 promotes initiatively piston rod 41, piston 42 walkings of hydraulic cylinder 40, initiatively the hydraulic oil in the hydraulic cylinder 40 is released by piston 42, hydraulic oil enters driven hydraulic cylinder 60 by withstand voltage oil pipe 50, and the piston 62 in the driven hydraulic cylinder 60, piston rod 63 are promoted, thereby promote hinged with it shear shank, shear shank is open, and scissors mouth closure realizes the pruning or the cutting of fruit of branch are plucked; During release handle 20, the back-moving spring 71 closed shear shanks between the shear shank, opposite with previous action, handle 20 is replied the position by piston rod 41 tops, and is ready for pruning once more.Initiatively hydraulic cylinder 40 and driven hydraulic cylinder 60 are the hydraulic means that generally use in the prior art, and concrete structure repeats no more.For ease of carrying, stock 10 can be a contractible type more piece sleeve pipe, and at this moment, withstand voltage oil pipe 50 can coil and be helical form, on the contractible type loop bar, follows the contraction of contractible type loop bar and elongates or shortens.
