The utility model content

The purpose of this utility model is to be power source with the direct current generator, and the structure of whole hedgerow tea bush trimmer machine is optimized and revised comprehensively, make machinery more reliable, safer, use more smoothly.

For achieving the above object, the technical solution of the utility model is, this kind electric hedgerow tea bush trimmer mechanism becomes to include, frame, power section, working portion, frame becomes an integral body with power section with the working portion structure, operate portions is made of cutter and bottom knife, power part drives cutter and bottom knife motion, be characterized in, described power section includes accumulator, direct current generator and driving mechanism, wherein driving mechanism is again by the transmission reel, last connecting rod and lower link constitute, described transmission reel is provided with eccentric wheel and following eccentric wheel, the transmission reel is fixedlyed connected with the direct current generator output shaft, last connecting rod one end pin-and-hole is movable mode with last eccentric wheel pin key and is connected, last connecting rod other end pin-and-hole then is movable mode with the terminal pin key of cutter and is connected, and lower link one end pin-and-hole is movable mode with following eccentric wheel pin key and is connected, and lower link other end pin-and-hole then is movable mode with the terminal pin key of bottom knife and is connected.For one-sided angle of throat sheet and bilateral angle of throat sheet, all can realize being connected with the technical program power-driven mechanism.

In technique scheme, described accumulator is not fixed in frame, promptly is in the flexible circuit conductor mode between accumulator and the direct current generator to be electrically connected.

In technique scheme, described frame is made of machine chamber, knife rest, main handle and secondary handle, and direct current generator, reel, upper connecting rod and lower connecting rod are set in the machine chamber, and knife rest is fixedly connected on holster shell, main handle is arranged at holster shell one end, and secondary handle then is fixed in the knife rest top.

The utility model has the advantages that power drive mechanism only relates to direct current generator, band eccentric wheel reel and connecting rod and working blade, structure is very simple, and mechanical movement is reliable; The secondary handle that has backplate has ensured the safety of using when double-edged blade is installed; Accumulator separates with the direct current generator installation site, the implementation flexible circuit conductor is electrically connected, make accumulator bear operation by the operator, alleviated the hand-held trimmer weight of operator on the one hand, reduce operation labor intensity, on the other hand, can prolong once and prune the activity duration, thereby satisfy urban landscaping and the tea plantation tea grower prunes the needs of tea tree operation by changing accumulator.

Specific embodiment

Embodiment one: the present embodiment structure as shown in Figure 1.

In the present embodiment, frame housing 1 and bottom 19 are metal casting, drive plate 6, reel 2, last eccentric wheel 14, following eccentric wheel 17 is a metal parts, cutter 21 and bottom knife 20 are one-sided angle of throat sheet, drive plate 6 is connected with the line shaft of direct current generator combination 7, last connecting rod 13 1 end pin-and-holes are set in eccentric wheel pin key 14, last connecting rod 13 other end pin-and-holes are set in cutter 21 pin keies, lower link 18 1 end pin-and-holes are set in down eccentric wheel 17 pin keies, lower link 18 other end pin-and-holes are set in bottom knife 20 pin keies, cutter 21 and bottom knife 20 have slotted eye, through hole about bolt 25 passes on blade slotted eye and the knife rest 5, and spacing with nut 26, and knife rest 5 is fixed as one by press strip 4 and holster shell 1.Main handle 10 is fixed in holster shell, and secondary handle 22 and secondary handle base 23 are fixed in press strip 4 tops by bolt nut, and it is opposite with the one-sided sword direction of blade that secondary handle 22 stretches out direction.Accumulator places knapsack, and the battery feed lead divides wrapped joint and black line joint, is connected to the red joint 8 and the black joint 9 of direct current generator combination 7.The power switch of direct current generator combination can be arranged on the main handle 10.

During the beginning operation, at first red joint of battery cable in the knapsack and black joint are docked with red joint of direct current generator and black joint, open the power switch on the main handle, motor rotates, the motor power axle makes drive plate, reel, last eccentric wheel, following eccentric wheel rotates thereupon, the end that upper and lower strut is connected with the eccentric wheel suit also rotates with eccentric wheel and does the circumference operation, this moment, upper and lower strut then returned multiple rectilinear motion with the other end that last bottom knife suit is connected, and then, bottom knife is done left and right sides relative displacement in the driving, realizes the pruning operation to the hedgerow tea tree.When operation a period of time, a group storage battery electric energy exhausts, and can change one group of new accumulator, realizes continuous operation, and the disposable activity duration is prolonged.

Embodiment two:

Present embodiment frame, power part structure are with embodiment one, difference is, what install is bilateral angle of throat sheet, when making trimmer along hedgerow tea tree surface back and forth movement, all can prune bilateral angle of throat sheet, can increase work efficiency, but owing to be the bilateral sword, need be to a backplate 24 as shown in Figure 2 be set between secondary handle and blade, thereby prevent that in the operating process, blade injures the operator.
