Abstract

The present invention relates to a DC electric trimmer which belongs to a DC electric tool. When the present invention is used, a 12V battery 27 is carried on a back of a user, and the positive and the negative poles of the battery and wiring terminals 5 of the positive and the negative poles of the trimmer are respectively connected by power cords 28. The right hand holds a front handle 6, the left hand holds a back handle 4, a thumb of the left hand presses a switch 3, a motor is immediately powered on to run, and an eccentric member 24 is driven to rotate. The connection among a connecting rod 26, a connecting piece 18 of an upper blade and the connecting rod and the upper blade 9 drive the upper blade 9 to slide in a reciprocating way, the reciprocating speed reaches 1800 times / min, and therefore, the purpose of trimming excess branches is achieved. The present invention is mainly composed of a sliding part-direct current motor 1, the eccentric member 24, the connecting rod 26, the connecting piece 18 of the upper blade and the connecting rob, the upper blade 9, a fixing part-base 25, a lower blade reinforcing frame 8, a lower blade 10, etc. The present invention has the advantages of simple and light structure, convenient and flexible use, economy, practicability, safety and no pollution. The present invention is suitable for the greening of gardens and the trimming of tea leaves.

Description

The direct current drive trimmer

Technical field:

The present invention relates to a kind of direct current drive that is applied to afforestation shrub and tea bush trimmer and prune machine tool.

Background technology:

At present known for greening shrub and tea bush trimmer, employed instrument is nothing more than 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, but its cost height, and gasoline engine is fragile, maintenance difficult, and Heavy Weight is dumb, start difficulty, use inconvenience, secondly be that voice is big, vibration is big, day oil consumption expense height (expending every day more than 10 yuan), and discharge a large amount of smog, environment there is pollution, is unfavorable for environmental protection.

Summary of the invention:

For overcoming the above-mentioned existing technological deficiency of pruning tool to greening shrub and tea bush trimmer, this use direct current provided by the invention has overcome above-mentioned deficiency effectively as " the direct current drive trimmer " of working power, and people can use it to carry out pruning work trippingly.

Technical scheme of the present invention is: a kind of direct current drive trimmer, the accumulator and the interior dc motor of machine that comprise the outer configuration of machine, cutter, bottom knife, front hand grip, back handle, power switch, machine base, connecting rod, eccentric part, it is characterized in that: an end of eccentric part directly is connected with the lower end of rotor axis of electric with thread, the other end directly is connected with bearing box respectively with thread by the two ends of connecting rod, and by bearing, screw is connected with it and is connected with connector, connector is connected by screw with cutter, the movable part of forming complete machine is done round linear slide thereby constitute cutter on fixed bottom knife.

Cutter is processed with 3 slip locating slots, is installed in cutter on the bottom knife with screw, pad respectively and keeps certain free gap by this locating slot, and bottom knife is fixed on bottom knife strengthening frame and the machine base by screw.

Last bottom knife is processed with corresponding tooth, and has the inclined-plane of 45, and the tooth of cutter is than the short 0.5cm of the tooth of bottom knife.

Front hand grip is installed in machine base the place ahead, and back handle is installed in the machine base rear, and power switch places the back handle top.

The accumulator of configuration is the 12V interchangeable battery.

The present invention is because the rotating speed height of the dc motor that uses, thereby 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 gasoline engine power trimmer, weight is 1/3, it is 1/60 that day is expended, and it is little to have a volume, simple in structure, easy to maintenance, economy and durability, easy to use flexible, safety non-pollution, daily cost is low (once available more than 8 hours as the charge in batteries of adapted 12V26AH, power consumption 0.3-0.4 degree expends about 0.2 yuan), dependable performance, advantage such as practical is current comparatively ideal mechanical pruning tool.Being widely used in afforestation department and tea grower uses as pruning tool.

Description of drawings:

Fig. 1 is the general structure front view, and Fig. 2 is the general structure vertical view, and Fig. 3 is a structure principle chart.

Among the figure: 1 is dc motor, and 3 is power switch, and 4 is back handle, 5 is power-line terminal, and 6 is front hand grip, and 8 is the bottom knife strengthening frame, 9 is cutter (coming and going sliding blade), 10 are bottom knife (maintaining static blade), and 11 is the bottom knife fixed screw, and 15 are the slip set screw, 16 are the slip setting-up piece, 17 are the slip locating slot, and 18 is connector, and 19 is the connector screw, 20 is bearing, 21 is connecting rod screw, and 23 is bearing box, and 24 is eccentric part, 25 is machine base, 26 is connecting rod, and 27 is accumulator, and 28 is power line.

Embodiment:

With reference to accompanying drawing 1,2,3, when manipulating, respectively the both positive and negative polarity of accumulator (27) and two binding posts (5) of trimmer both positive and negative polarity are connected with power line (28), accumulator is carried on the back at back, the right hand is held front hand grip (6), and left hand is held back handle (4), and the left hand thumb is pressed power switch (3), direct current generator (1) is promptly connected the power supply entry into service, drives eccentric part (24) rotation; Because connecting rod (26), bearing (20) are connected with connector (18) with eccentric part (24) by screw (21) respectively with bearing box (23), under the wobbler action of eccentric part, thereby make connecting rod do the front and back back and forth movement; Again because cutter (9) and connector (18) are connected the positioning action that is processed with 3 slip locating slots (17) and slip set screw (15), slip setting-up piece (16) with cutter by screw (19), add certain free gap is arranged between bottom knife, so cutter is just and then done round linear slide simultaneously on fixed bottom knife, at this moment go up between the tooth of bottom knife and the tooth with regard to repetition alternate with each other, thereby the branches and leaves that enter in the cutter tooth are cut, played the pruning effect.In use, adopt intermittently and press, decontrol and close (3), be i.e. press switch when feed is pruned and make it to prune; withdrawing or do not have and decontrol switch when pruning; make it to quit work, so promptly be beneficial to and prolong battery service time, play the effect of saves energy and protection trimmer again.
