CN2824540Y - Corn picker unit of fruit stalk combined collection harvester - Google Patents

Abstract

The utility model discloses an ear picker unit of corn harvester for harvesting both stalks and ears, which comprises two picking rolls, wherein the front ends of the two picking rolls are guide cones, and the rear ends are roll shaft sleeves, straight-cut gears are respectively arranged on roll shafts which are arranged in the roll shaft sleeves; main picking rolls are arranged between the guide cones and the roll shafts, and the two picking rolls are arranged in bearing seats on a machine frame body via the roll shafts. A power-input gear which is arranged on one roll shaft is driven to rotate by a power output gear. The roll lengths of the two picking rolls are from 800cm to 500cm; the two main picking rolls are respectively composed of an introducing roll and a main picking pipe which are both conical bodies with smooth surfaces; the surface of each main picking pipe is provided with oblique crossing salient ribs, and the surface the introducing roll of one main picking roll is provided with a spiral salient rib. A clamping gap formed between the two oblique crossing salient ribs is changed from big to small, and the corn stalk which enters the clamping gap can not break due to brittleness. The fruit ear and the picking rolls are in smooth-surface contact, so the seed crashing ratio is low. The utility model has the advantages of simple structure, small volume, low cost of products and reliable performance.

Description

The ear-picking unit of stalk-spike-reaping maize harvesting machine

Technical field

The utility model relates to the results of standing crop, especially a kind of ear-picking unit that is applicable to the stalk-spike-reaping maize harvesting machine of harvesting corn.

Background technology

China is corn planting big country, and total cultivated area reaches 3.67 hundred million mu.At present, penetration and promotion along with agricultural mechanization production, the mechanization of harvesting corn is applied, its function mainly is to carry out corn ear results and straw-returning, horizontal spiral muscle snapping bar two row backpack combined harvesters as Shandong Dafeng Machinery Co., Ltd., the rich mechanical Co., Ltd of Shandong state and Zibo Xiangnong Machinery Co., Ltd produce have the advantage that harvest corn speed is fast, fruit ear seed damage rate is low, straw-returning is satisfactory for result.The ear-picking unit of the horizontal spiral muscle snapping bar two row backpack combined harvesters of above-mentioned manufacturer production all is made up of a pair of snapping bar in relative rotation, roller is about 1150cm, the front end of two snapping bars is respectively starting taper, the rear end is a roll sleeve, pluck the fringe home roll for what be provided with the smooth face of cylinder between starting taper and the roll sleeve, two rear portion, the smooth face of cylinder correspondences of plucking the fringe home roll are provided with the oblique convex tendon, wherein a snapping bar is provided with spiral convex rib on the smooth face of cylinder between oblique convex tendon and the starting taper, be respectively equipped with roll shaft in two roll sleeves, be respectively equipped with the straight-tooth gear that is meshed on the roll shaft, snapping bar is in roll shaft is installed in the bearing block that is arranged on the Rack Body, and on a roll shaft, be provided with power input gear, drive by power output gear and rotate.For example, " core ear-picking roller " of the just open a kind of like this structure of Chinese utility model patent specification of the CN2387717Y that announced on July 19th, 2000.During work, maize straw is plucked by the spiral convex rib delivery to two on the smooth face of cylinder of snapping bar between the oblique convex tendon of fringe home roll, by two oblique convex tendon clampings and in rotary course, finish draw the footpath and ear harvesting operation.Along with Developing of Animal Industry, the maize straw of chopping obtains user's approval as green fodder, so will set up straw chopping apparatus in the ear-picking unit bottom of existing maize harvesting machine, to realize the stalk-spike-reaping purpose.But according to the needs of the design and the installation of shredding mechanism, existing snapping bar is long, and volume is bigger, and the product cost height is so can not be fit to the stalk-spike-reaping maize harvesting machine.Simultaneously, because two pluck the oblique convex tendon that rear portion, the smooth face of cylinder of fringe home roll correspondence is provided with, the folder crack that forms when relatively rotating is little, and the maize straw root that maize straw is especially thick and moisture content is higher is prone to brittle failure when just entering two oblique convex tendons folder crack.

Summary of the invention

The utility model is bigger in order to solve in the prior art ear-picking unit volume, the folder crack of two oblique convex tendons is little, maize straw is prone to the deficiency of brittle failure when entering two oblique convex tendons folder crack, and provide a kind of ear-picking unit of stalk-spike-reaping maize harvesting machine, the ear-picking unit of this stalk-spike-reaping maize harvesting machine not only volume is little, product cost is low, and maize straw brittle failure can not occur when entering two oblique convex tendons folders crack.

The technical scheme that the utility model technical solution problem is adopted is: a kind of ear-picking unit of stalk-spike-reaping maize harvesting machine, comprise two snapping bars, the front end of two snapping bars is respectively starting taper, the rear end is respectively roll sleeve, be provided with between starting taper and the roll sleeve and pluck the fringe home roll, pluck on the fringe home roll and be respectively arranged with spiral convex rib, the oblique convex tendon, be respectively equipped with roll shaft in two roll sleeves, be respectively equipped with the straight-tooth gear that is meshed on the roll shaft, two snapping bars are respectively in roll shaft is installed in the bearing block that is arranged on the Rack Body, and on a roll shaft, be provided with power input gear, power input gear is driven by power output gear and rotates, characteristics are the long 500cm-800cm of two snapping bar rollers, two pluck the fringe home roll respectively by guide-in roller with pluck fringe and be responsible for and form, guide-in roller and pluck fringe and be responsible for and be respectively ganoid bullet, described oblique convex tendon are relatively arranged on respectively to be plucked fringe and is responsible for the surface, and described spiral convex rib is arranged at a wherein guide-in roller surface of plucking the fringe home roll.Roller of the present utility model is long to be shortened, and volume is little, and product cost is low; Two pluck the fringe home roll respectively by the guide-in roller of bullet with pluck fringe and be responsible for and form, are responsible for the folder crack that forms between the lip-deep oblique convex tendon by diminishing greatly gradually at the fringe of plucking of bullet, and the maize straw root can not produce brittle failure when two oblique convex tendons press from both sides the crack entering; Corncob is plucked in the fringe process and is contacted with the shiny surface of snapping bar, and the seed damage rate is low.

Two pluck the fringe home roll in relative rotation rotating speed be 900-1000 rev/min.

The beneficial effects of the utility model are, simple in structure, product cost is low, dependable performance, and fruit ear seed damage rate is low.
