Abstract

The utility model provides a secondary corn ear picking and cleaning device which is matched with a corn combine and is arranged on the top end of a lift conveyer of the prior corn combine, wherein the top end of the lift conveyer is connected with a frame; the upper part of the frame is parallelly connected with an upper roll and a lower roll rotating towards each other; the rear ends of the upper roll and the lower roll are connected with a third axle roll; the axle ends of the three rolls are driven through gears; moreover, one side of the upper roll and one side of the lower roll are respectively provided with a guide plate at one side. With a simple and reasonable structure and reliable performance, the device completely solves the problem of impure corn ear picking, thereby improving the comprehensive performance index of a corn combine.

Description

The supporting secondary of a kind of and corn combine is plucked the assorted clearly device of fringe

Technical field

The utility model relates to agricultural harvesting machinery, particularly corn combine.

Background technology

The ceding of Taiwan of existing corn combine exists the problem of breaking the stem stalk, and traditional technology is that one group of row's stem device is set on the top of ear or transport device, and purpose is that impurities in the fruit ear and long shoot stalk are removed.Unreasonable because of row's stem device technique exists and cleans thoroughly and sting the fringe phenomenon, makes containing of fruit ear case of the assorted not only unresolved breakage rate that increases fruit ear on the contrary of problem.Cause the high problem of fringe percentage of impurity of plucking of corn combine not solved at all.

Summary of the invention

The purpose of this utility model is the deficiency that overcomes existing corn combine technology, provide secondary a kind of and that corn combine is supporting to pluck the fringe impurity-removing mechanism, it is not only simple and reasonable, and installation, use, easy to maintenance, dependable performance is fit to various corn combines supporting.Fundamentally can solve and pluck containing of fringe of assorted problem, can improve the integrated performance index of corn combine.

The purpose of this utility model realizes by following measure: above existing exit, corn combine elevator top one group of secondary snapping bar assembly is set, when elevator also passes through with the below of secondary ear harvesting stick assembly during with the exit of impure fruit ear by the top simultaneously, the secondary snapping bar of running has been caught long shoot stalk and loose weeds and the corn bud skin in the elevator, and corncob is separated once more with stem stalk weeds.Obtain assorted clearly purpose.

Connect elevator on the body of corn combine, the top attachment secondary of elevator is plucked the assorted clearly device of fringe.The top of elevator connects frame, connect a pair of top roll and the lower roll of rotation in opposite directions side by side in the exit of the top corn ear that is positioned at the elevator chain harrow of frame, the rear portion of top roll and lower roll connects the 3rd beaming roller, the axle head of top roll, lower roll and the 3rd beaming roller links by gear, and gear shaft is subjected to the transmission of reaping machine dynamical system.One side of top roll and lower roll is equipped with guide plate, and guide plate is connected in the back side or the front of device as required.

The beaming roller diameter of above-mentioned top roll and lower roll is 40mm～90mm, and the helix 10 that is provided with on the beaming roller is 5mm～10mm for 5mm～10mm, helix width highly, and the lead of helix is 32mm～128mm.

Above-mentioned have secondary to pluck the top roll of fringe effect and the helix in the same way on the lower roll is left-handed or dextrorotation all can, the two forms ' cross ' crosspoint to the interface point circulation of changeing spiral in opposite directions, has the fringe of plucking and row's stem function.

The 3rd above-mentioned beaming roller is a major axis, is axially arranged with uniform convex tendon on the major axis, also can be set to chopper by the 3rd beaming roller.

Its principle is: when the below that elevator is also plucked the fringe cleaning plant with secondary during with the exit of impure fruit ear by the top is simultaneously passed through, the secondary snapping bar has been caught long shoot stalk and loose weeds and the corn bud skin in the elevator, and corn ear is separated once more with stem stalk and weeds.Fundamentally solved and plucked containing of fringe of assorted problem, improved the integrated performance index of corn combine.This apparatus structure advantages of simple, and installation, use, easy to maintenance, dependable performance is fit to various corn combines supporting.Fundamentally solved and plucked containing of fringe of assorted problem, improved the integrated performance index of corn combine.

In the accompanying drawing: 1 corn combine body; 2 elevators; 3 secondaries are plucked the assorted clearly device of fringe; 4 frames; 5 guide plates; 6 top rolls; 7 lower rolls; 8 the 3rd beaming rollers; 9 elevator chain harrows; 10 helixes; 11 convex tendons.

Embodiment

Embodiment 1: with reference to accompanying drawing is an embodiment of the present utility model.Connect elevator 2 on the body 1 of corn combine, the top attachment secondary of elevator 2 is plucked the assorted clearly device 3 of fringe.The top of elevator 2 connects frame 4, makes elevator 2 lengthenings.Connect a pair of top roll 6 and the lower roll 7 of rotation in opposite directions side by side in the exit of the top corn ear that is positioned at elevator chain harrow 9 of frame 4, there is secondary to pluck the top roll 6 of the assorted clearly function of fringe and the rear portion of lower roll 7 connects the 3rd beaming roller 8, the axle head of top roll 6, lower roll 7 and the 3rd beaming roller 8 links by gear, and gear shaft is subjected to the transmission of reaping machine dynamical system.Guide plate 5 is equipped with in the front of top roll 6 and lower roll 7.

The above-mentioned top roll 6 and the beaming roller diameter of lower roll 7 are 70mm, and the height of the helix 10 that is provided with on the beaming roller is 8mm, and the helix width is 8mm, and the lead of helix is 85mm.

The above-mentioned top roll 6 and the helix in the same way on the lower roll 7 10 that have secondary to pluck the fringe effect are left-handed, and the two forms ' cross ' crosspoint to the interface point circulation of changeing spiral in opposite directions, has the fringe of plucking and arranges the stem function.

The 3rd above-mentioned beaming roller 8 is a major axis, is axially arranged with 6 uniform convex tendons 11 on the major axis.
