Description

The adjustable picker for tuber crops of perching knife

First, technical field

The present invention relates to agricultural equipment technology field, more particularly to a kind of adjustable picker for tuber crops of perching knife.

2nd, background technology

In recent years, deepening continuously with agriculture industrialization structural adjustment, potato class are used as the important industrial crops in Shandong Province And brand article, cultivated area increases year by year, but potato type harvesting high labor intensive, production cost height, working performance are low, Nong Minke Hope that, using advanced potato type harvesting machinery, the demand of Shandong Province's potato type harvesting machinery increasingly will increase.Equipment in the market Use range also has certain limitation, has certain wanting to working width, edaphic condition, crop requirement, results opportunity etc. Ask, can not especially meet the requirement of different potato class difference excavating depths, process is harvested easily by potato class shovel wound or sliding trackle, cause to receive Quality reduction is obtained, farmers' income is reduced.Therefore, research improves the performance and operation quality of potato type harvesting machinery, for mitigation The labor intensity of peasant, increase farmers' income, it is significant.

3rd, the content of the invention

In order to solve the above problems, this utility model provides a kind of adjustable picker for tuber crops of perching knife.

A kind of adjustable picker for tuber crops of perching knife, including disengaging latch, land wheel, frame and the knife rest being fixed in frame and spiral shell Bar governor motion.Land wheel is arranged on below frame, for walking；Disengaging latch is arranged on the inside of the frame at knife rest rear；

Knife rest front end both sides are respectively provided with one and cut native disk；Pacify side by side two knife rest front ends cut between native disk Equipped with many perching knife, about 30 millimeters of spacing between adjacent perching knife；Knife rest rear end both sides are movable installed in machine by bearing pin In axle sleeve on frame, bearing pin freely can be rotated in axle sleeve, form a hinged support；Screw rod regulating mechanism is by swivel nut and is arranged on Two thread compositions inside swivel nut upper and lower ends, two thread thread rotary orientations are conversely, the processing of swivel nut endoporus two ends There is screw thread, the thread rotary orientation at two ends is conversely, installation can be screwed with two threads respectively.Screw rod regulating mechanism two ends connect respectively Connect relieving tool post and frame, rotate swivel nut, the thread at swivel nut two ends can precession or back-out simultaneously, to control relieving tool post around pin Axle is rotated, so as to adjust perching knife angle of penetration, so as to change excavating depth；Disengaging latch is located at perching knife rear end close to installation；Separate Chain total length is more than or equal to 5 meters, and the potato class that perching knife is given birth to fall on disengaging latch, and potato class and soil block are conveyed on disengaging latch backward During separated by the vibration of disengaging latch.

During work, this utility model is articulated in rear tractor by three-point hitch carries out operation, can be according to potato Class species is different and difference harvests excavating depth and requires to adjust perching knife angle of penetration, so as to change excavating depth, harvests damage and damages Lose few, soil block good separating effect, efficiency high, working stability.

5th, specific embodiment

The adjustable picker for tuber crops of a kind of perching knife, mainly by groups such as frame, knife rest, disengaging latch, screw rod regulating mechanism, land wheels Into.Install many perching knife on knife rest, adjacent perching knife is spaced about 30mm, can reduce hilling.Behind knife rest, two ends are equipped with bearing pin, frame Relevant position mounting sleeve, bearing pin can be freely rotated in axle sleeve, and bearing pin forms a hinged support with axle sleeve.Governor motion is by two Individual thread and swivel nut composition, reversely, swivel nut endoporus two ends process reverse thread to two thread screw threads, respectively with screw rod Coordinate.Thread two ends connect relieving tool post and frame respectively, turnbarrel, and thread precession simultaneously or back-out can change Pull bar length, relieving tool post are rotated around bearing pin, can adjust perching knife angle of penetration, so as to change excavating depth；For improve potato class and The separating effect of soil block, disengaging latch total length are more than or equal to 5 meters, and potato class and soil block are leaned in course of conveying on the disengaging latch backward The vibration of disengaging latch is separated.

During work, the length that the excavating depth rotary threaded sleeve for requiring adjusts thread is harvested according to plot, encloses knife rest Rotate around hinged support, so that perching knife obtains optimal embedded depth；Native disk is cut by the soil in this stroke working width Separate with both sides soil；The potato class that perching knife takes together are risen together with soil block transports to disengaging latch, with separation chain leading after course of conveying Soil block and potato class are separated because separating chain vibration.

Protection scope of the present invention not limited to this, skill of any those familiar with the art in present disclosure In the range of art, the simple change or equivalence replacement of the technical scheme that can be become apparent to each fall within protection scope of the present invention It is interior.
