Description

The direct current drive trimmer

The direct current drive trimmer is a kind of electric mower tool that utilizes accumulator as power source, belongs to the direct current electric power tools type.

At present, various places are for the flowers and shrubs of greening and be engaged in the pruning work of tealeaves plantation, and employed pruning tool has two kinds of the manual scissors of traditional type and the motor-driven trimmers of gasoline engine, and its manual scissors labour intensity is big, effect is low, incompatibility development today trend; Though and the motor-driven trimmer work efficiency of gasoline engine height, its cost height, and gasoline engine is fragile, maintenance difficult, Heavy Weight is dumb, starts difficulty, uses inconvenient; Next is that noise is big, vibration is big, day oil consumption expense height (expending RMB every day more than 10 yuan), and discharges a large amount of smog environment is had pollution, is unfavorable for environmental protection.

The objective of the invention is to overcome the defective of prior art, this direct current drive trimmer of inventing out has overcome above-mentioned deficiency effectively, and people can utilize it to carry out pruning work trippingly.

The cunning moving part of direct current drive trimmer, standing part and casing are formed (seeing Figure of description).Slipper is mainly by dc motor 1, eccentric part 24, connecting rod 26, and cutter and connecting rod connector 18 and cutter 9 are formed (shown in Figure 3); Standing part is by machine base 25, bottom knife strengthening frame 8, and bottom knife 10 and screw 11,15 etc. are formed (Fig. 1, shown in Figure 2); Housing part is by shell 2, power switch 3, and back handle 4, power-line terminal 5, front hand grip 6, safety guard 7 and

screw

13,14 are formed (shown in Figure 1).Last bottom knife has corresponding tooth, and the tooth of cutter is than short 0.5 centimetre of the tooth of bottom knife (help like this with branches and leaves are disposable cut flat), and has the inclined-plane of 45 mutually, to increase the sharpness of tooth mouth.When manipulating, 12 overhead accumulators 27 are carried on the back at back, respectively the both positive and negative polarity of accumulator and two joint pins 5 of both positive and negative polarity of trimmer are connected with power line 28 again, the right hand is held front hand grip 6, left hand is held back handle 4, the left hand thumb is pressed switch 3 (shown in Figure 2), and dc motor is promptly connected the power supply entry into service, drives eccentric part 24 rotations; Connect pavilion 26, bearing 20 is connected with connecting rod connector 18 with cutter with eccentric part 24 by connecting rod screw 21 respectively with bearing box 23.Because the wobbler action of eccentric part, thereby make connecting rod do back and forth movement.Again because cutter 9 is connected by screw 19 with connecting rod connector 18 with cutter and cutter 9 is processed with 3 slip locating slots 17 and goes up fixedly slip screw 15 of bottom knife, the stationary positioned effect (shown in Figure 3) of upper blade slides setting-up piece 16, the fixing round linear slide so cutter also follows suit simultaneously, at this moment the tooth of going up bottom knife is with regard to repetition alternate with each other, thereby the branches and leaves that enter in the cutter tooth are cut, played the effect of pruning.In use, adopt and intermittently press switch 3, be i.e. press switch 3 when feed is pruned and make it work, relieving switch 3 during withdrawing helps prolonging battery service time like this.

Because the rotating speed height of the dc motor on this machine, the round sliding speed of cutter is also fast, per minute can reach 1800 times, the speed of its pruning is also just fast, improved operating efficiency greatly, compare with gasoline engine power trimmer, its cost is 1/4 of a petrol power trimmer, and weight is 1/3, it is 1/60 that day is expended, and it is little, simple in structure, easy to maintenance to have a volume, economy and durability, flexible and convenient to use, pollution-free, daily cost is low, and (accumulator as adapted 12V 26AH fills once electric available more than 8 hours, power consumption 0.3-0.4 degree, expend about 0.2 yuan) etc. advantage, be widely used in afforestation department and tea grower to use as pruning tool, reach the invention effect.

The direct current drive trimmer, its safe in utilization, convenient, flexible, dependable performance, practical, be current comparatively ideal mechanical pruning tool, belong to invention class invention product.
