Abstract
The invention belongs to the technical field of corn harvesters and relates to an ear picking device which can be installed on the corn harvesters, in particular to a corn ear-picking stubble-cutting stem-cutting header capable of breaking off ears from upside. The corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside comprises a roller and plate combined type ear picking unit, a stem pulling and conveying device and a stubble-cutting stem-cutting device. The corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside is characterized in that the roller and plate combined type ear picking unit is composed of a pair of conveying rollers and a pair of ear baffles arranged below the conveying rollers, and the roller and plate combined type ear picking unit is fixedly connected with a machine frame of a harvest machine and is arranged obliquely in the mode that the front portion is high and the lower portion is low relative to the ground (when the roller and plate combined type ear picking unit is in work); the stem pulling and conveying device is a telescopic rod tooth type mechanism and is arranged behind the ear picking unit; the stubble-cutting stem-cutting device is composed of a stubble-cutting device and a stem-cutting device, the stubble-cutting device is arranged below the ear picking unit, and the stem-cutting device is arranged below the stem pulling and conveying device. According to the corn ear-picking stubble-cutting stem-cutting header capable of breaking off the ears from upside, the bending break principle of manual corn ear picking is simulated, the problem that corns are damaged when an existing stretching and squeezing method is adopted can be thoroughly solved, and ear picking power consumption can be greatly reduced.
Description
Technical field
The present invention relates to a kind of ear-snapping unit being applicable to be arranged on maize harvesting machine, belong to corn harvesting machine technical field.
Background technology
Ear-picking unit is the key working part of maize harvesting machine, can be divided into roll-type and board-like two kinds at present by operation principle.Board-like ear-picking unit belongs to passive-type harvesting, is the root of being lived corn ear by gear fringe board, by force corn stem is broken the object realizing harvesting by stem pulling roller.This device easily causes the problem of disconnected stem, blocking.The operation principle of roll-type completes ear harvesting operation by conveying roller to the stretching of corn stem and fruit ear and squeezing action.In existing roll-type ear-picking unit, most of conveying roller adopts the structure of surperficial additional spiral fin, produces extruding and the active force rubbed, very easily chew corncob to fruit ear root, cannot fundamentally solve conveying roller to the extruding of corncob with chew effect.Want to solve this difficult problem, be necessary to seek new principle and new equipment.
Research finds, what people carried out corn picker employing is makes that fruit ear is bending to fracture, and forms due to the special material of staff, very little to the extruding force of corn ear, can not produce and damage corn phenomenon, become the basis of corn picker new method research.
Summary of the invention
The object of this invention is to provide and one breaks fringe formula corn picker and cut stubble and cut the stem ceding of Taiwan, to overcome the shortcoming of prior art.
In order to achieve the above object, the technical solution used in the present invention is: by the achievement of bionics Study, be conceived to the innovation of harvesting method, by imitating the principle of manually plucking corncob work, design be connected with harvest corn frame on break fringe formula corn picker and cut stubble and cut the stem ceding of Taiwan.
By reference to the accompanying drawings, be described as follows: one is broken fringe formula corn picker and cut stubble and cut the stem ceding of Taiwan, comprise harden box-like ear-picking unit, stem stalk of roller to pull over mechanism and cut stubble and cut stem device, it is characterized in that: described roller hardens box-like fringe unit of breaking by a pair conveying roller 2 be placed in this and form a pair gear fringe plate 1 below conveying roller, during work, this mechanism is fixedly connected with the frame of harvest machinery, and with ground Cheng Qiangao after low heeling condition configure, described stem stalk mechanism of pulling over is the tooth-like mechanism of expansion link, and this organization establishes is in breaking fringe unit rear, batch organization establishes, by cutting batch device and cutting stem device and form, is cut in the below of breaking fringe unit by described Qie Chaqie stem mechanism, cuts stem organization establishes and to pull in stem stalk the below of mechanism, during work, milpa is guided by clamping device and enters roller and harden and box-likely break fringe unit, corn ear is made to be in the below of conveying roller 2, cut batch device the plant entering snapping bar is cut off, two conveying rollers 2 of opposite direction rotating clamp and guide plant upwards to move backward, gear fringe plate 1 contacts fruit ear, and the downward thrust of side direction is applied to fruit ear, make fruit ear produce bending fractureing and depart from plant, maize straw after harvesting is kept upright state, maize straw is left behind by the pull over expansion teeth 3 of mechanism of stem stalk, maize straw is fallen back ground, cut stem device and the stalk retracting ground is cut stem also field.
The surface of described conveying roller 2 is provided with the spiral ridge of oppositely distribution each other, and its core adopts body material, and spiral ridge adopts flexible material to make; Described gear fringe plate 1 is placed in below conveying roller 2, exists in pairs, is main spike cutting machine structure.
Large rear end, front end, gap between described a pair conveying roller 2 is little.
The drive manner of described a pair conveying roller 2 be each other forward and inverse hour hands to inner rotary.
Described stem stalk mechanism of pulling over is the tooth-like mechanism of expansion link, and be made up of expansion teeth 3, Eccentric cylinder 4 and flexible teeth groove 5, its rotation direction is forwards.
Described batch device of cutting is cut batch blade 11 by a pair and is cut batch tubular axis 10 and forms.
Described stem device of cutting is made up of moving knife seat 8, the knife section 7 evenly installed, moving knife seat axle 9 and ledger-plate 6.
The invention has the beneficial effects as follows: 1) the present invention imitates the bending principle of manually plucking corncob, fundamentally can solve the corn damage that existing stretching pressing method causes; 2) by the combination of conveying roller and gear fringe plate, realize imitating the effect of manually plucking corncob, effectively prevent from chewing corn ear, fundamentally solve conveying roller to the extruding of corn with chew effect; 3) conveying roller is to inner rotary, realizes the upwards function of transportation to stem stalk; 4) keep off the root that fringe board lives corn ear, realize the effect of manually breaking off corncobs downwards; 5) gap between conveying roller is greater than maize straw diameter, there is not the squeezing action to corn stem, can obtain complete corn stem, is also conducive to the comprehensive utilization of corn stem.
