Description

Electronic secateurs

Technical field

The utility model relates to a kind of instrument of agriculture and forestry operation, particularly a kind of electronic secateurs of operating on the ground that stands in.

Background technology

Along with the development of fruit industry, develop into production in blocks from single of evacuating and fragmentary plantation, the orchard is more and more, and the area in orchard is increasing, for people provide various appetizing fruit.But whenever the fruit mature period, the harvesting of fruit is to make orchard worker's pain in the neck, and what get at is also easy to handle, though waste time and energy, plucks and gets up can be said to be convenient; And when people can't pluck on the ground, can only take to climb the way of branch, and standing in tree to stick, a hand will buttress branch, keeps one's balance, and the another hand could fruit-picking.The fruit of every harvesting one tree also will be in the tree moves everywhere, has plucked the fruit of one tree after, climb up other one tree again, from answering above-mentioned work, bother very much repeatedly, fruit-picking efficient is low, and very dangerous.

Can stand in the overhead fruit picking device of operating on the ground though also have at present,, waste time and energy, operate also cumbersome owing to when using, drive backguy control and shear by the pulling joystick.

Summary of the invention

The purpose of this utility model provides a kind of easy to use, simple to operate, electronic secateurs in labour-saving.

Electronic secateurs of the present utility model, comprise the shearing tool of expansion link, expansion link upper end, shearing tool comprises ledger-plate and knife section, and described knife section is controlled by motor-driven controlling organization, this controlling organization can make knife section around the positive and negative rotation of fixed axis, thereby makes shearing motion with ledger-plate.

Described controlling organization comprises the worm screw on the motor output shaft, and the worm gear that cooperates with worm screw has a pinion on worm gear is coaxial, and pinion cooperates with one section arc tooth on the knife section.

Described controlling organization comprises the worm screw on the motor output shaft, the worm gear that cooperates with worm screw, worm gear one side has a cam, and the knife section bottom has one can promote the guiding mechanism that knife section rotates when rotating by cam, guiding mechanism comprises extruded segment and reset section, and the back-moving spring of knife section is installed.

Described controlling organization comprises the worm screw on the motor output shaft, the worm gear that cooperates with worm screw, one pinion is arranged on worm gear is coaxial, other has a gear wheel to cooperate with pinion, in gear wheel one side one cam is arranged, the knife section bottom has one can promote the guiding mechanism that knife section rotates when rotating by cam, and guiding mechanism comprises extruded segment and reset section, and the back-moving spring of knife section is installed.

The utility model is reasonable in design, owing to,, therefore not only be suitable for fruit-picking because it can regulate height by expansion link by by motor-driven controlling organization control shearing tool, also can be used for the afforestation pollard, can improve the efficient of fruit-picking and pollard.It is simple in structure, portably uses conveniently, and is laborsaving, can fall the labour intensity of agrisilviculture.
