Abstract

The utility model discloses a hand-held electric dresser for flowers and trees which is mainly composed of a fixed cutter head, a movable cutter head, an outer shell, bevel gears, a bearing, couplers, a wire flexible shaft, a connecting sleeve and a hose. The hose and the handle of the dresser are connected by the connecting sleeve 8 with screw threads. The motive power of a power case is transmitted to the terminal of the handle of the dresser through the wire flexible shaft. Then the motive power is transmitted to the shaft of the bevel gear through the two telescopic combined couplers which connect two flexible shafts. Through the engaging transmission of the two bevel gears, the movable cutter head fixedly connected with a vertical gear shaft rotates. The inner ring of the bearing is respectively used as the support of the two gear shafts. The outer ring of the bearing is connected with the outer shell. The fixed cutter head fixed with the outer shell is used as a cutting support.

Description

Hand-held electric dresser for flowers and trees

The utility model belongs to the horticultural machinery class.

It is by manpower that existing flowers and trees are pruned, with the special-purpose shear of pruning flowers and trees (a kind of blade that upper and lower two company's handgrips are arranged, terminal hinged at blade cutting edge with rivet, the instrument that is similar to common scissors that handgrip and cutting edge face are angled) prune.

The purpose of this utility model is to adopt electric trimmers to replace manpower to prune, and reduces labor intensity, and improves pruning speed (about more than 10 times) greatly.

The utility model technical solution:

It is power that this trimmer adopts by battery-driven direct current generator.Trimmer is designed to hand-held.Mainly containing stationary knife dish 1 (is a circular pieces of being made by sheet metal, the profile of tooth blade of some definite shapes that distributing in the scope of this part about 150), movable knife disc 2 (being the part of several leaf blades that are uniformly distributed along the circumference of making by sheet metal), shell 3, bevel gear 4, bearing 5, shaft coupling 6, Bowden cable 7, adapter sleeve 8 and flexible pipe more than 9 parts are formed.Except that cutterhead and several miniature bearing, all the other all adopt engineering plastics to make.Electromotor and accumulator place a chassis that steamboat is housed to be, add drawing handle and outer cover and form a small and exquisite spcific power case.Power switch is located on the handle.Adopt the Bowden cable transmission between headstock and the trimmer, flexible axle connects with trimmer union end employing activity, be convenient to take apart and deposit (if can adopt the less efficient accumulator of volume, headstock also can adopt piggy-back structure).

The utility model advantage: this trimmer technical difficulty is little, and structure and transmission of power are simple, and power attenuation is little, and is easily manufactured.Because of most parts adopt engineering plastics, thus in light weight, use, easy and simple to handle, safety.Labour intensity is little, and pruning speed is fast.

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with Fig. 1 the utility model is further described:

Headstock power reaches trimmer handgrip end through Bowden cable 7; The Bowden cable 7 outer flexible pipes 9 that are with, flexible pipe 9 links with threaded adapter sleeve 8 with the trimmer handgrip; Power just passes on the bevel gear shaft through two box-like shaft couplings 6 of telescopic that connect flexible axle again, two bevel gears 4 all are an integral body with its gear shaft, through the engaged transmission of two bevel gears 4, the movable knife disc 2 that is connected with the vertical teeth wheel shaft also rotates; As the supporting of two gear shafts, the outer ring links to each other with shell 3 inner ring of bearing 5 respectively; The stationary knife dish 1 that links to each other with shell 3 is as the cutting supporting.Along with the reach of trimmer, movable knife disc 2 cuts the flowers and trees cane that enters between two cutterhead cutting edges under the cooperation of stationary knife dish 1.

Claims

A kind of electronic flowers and trees trimmer, it is characterized in that by movable knife disc 2, stationary knife dish 1, drive bevel gear 4, bearing 5, the box-like shaft coupling 6 of telescopic, the hand-held cutter of garden disc type that shell 3 and Bowden cable 7 are formed, the box-like shaft coupling 6 of Bowden cable 7 and telescopic has been formed the power transmission structure between headstock and the trimmer, a pair of drive bevel gear 4 is by bearing 5 supportings, the outer ring of bearing 5 is by 3 supportings of trimmer shell, movable knife disc 2 directly is connected mutually with the vertical teeth wheel shaft, and stationary knife dish 1 is connected with shell 3.
