Abstract
The utility model relates to a cutting platform for harvesting maizes. The cutting platform comprises spiral roll ear picking devices arranged in parallel and ear conveying augers arranged at the rear parts of the ear picking devices, wherein each ear picking device comprises a stalk pulling roll, an ear picking bracket and a grain teasing chain. The front end of each stalk pulling roll is provided with spiral salient edge guide cones which pairwise rotate correspondingly, and chopping blades are uniformly arranged at the rear part of each stalk pulling roll in an axial direction; grain dividers are distributed in parallel at the front end of an outer cover on each ear picking device. The cutting edge angles of the chopping blades in staggered arrangement are from 30 DEG to 35 DEG, and greater coincident end surfaces mutually jogged can be formed between the cutting edges of the blades during rotation, so snatching force and the downward tensile force of the stalk are big, and the slip rate is low; thus, the impact force of the fruit ear on an ear picking board can be reduced, and the loss of the fruit ear seeds is reduced; simultaneously, the initial installation angle and the grain dividing angle of the grain dividers are small, so the requirements for harvesting crops of the fruit ears with a low ear position and the lodging maizes can be satisfied. The lower end of each stalk pulling roll is an overhung open end, so the axiality of the stalk pulling rolls is ensured; simultaneously, the utility model has the advantages of the simple integral structure, convenient installation and adjustment, difficulty reduction of the installation and debugging, and production cost reduction.
Description
Technical field
The utility model belongs to agricultural harvesting machinery, is specifically related to a kind of Maize harvesting machine.
Background technology
Corn is a kind of long-stalked crops, not only will cut down stalk during results, also will take fruit ear from stalk, also need for making straw-returning stalks cutting, so the farm work that harvesting corn is a multiple operation, workload is big.The stem roll structure shape of drawing of the maize harvesting machine ceding of Taiwan at present both at home and abroad can be divided into star structure and fin structure substantially, and wherein the advantage of star structure is a stable working, but its grasp force is little, draws in the stem process stalk slip rate bigger; Though fin structure grasp force is big, fruit ear was big to the impulsive force of plucking the fringe plate when it plucked fringe, caused the loss of fruit ear seed serious.In addition, the stem roller that draws in the general ceding of Taiwan is that bearings at both ends supports, and this structure must guarantee to draw that higher axiality is arranged between the stem roller when processing and Installation and Debugging, thereby the Installation and Debugging difficulty is big, has strengthened production cost.
Goal of the invention
The purpose of this utility model be to provide a kind of simple in structure, be easy to Installation and Debugging, Maize harvesting machine that the fruit ear Loss Rate is low, to overcome the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model is achieved in that this Maize harvesting machine comprises the spiral pair roller ear-picking unit and the fruit ear conveying screw feeder of being located at the ear-picking unit rear portion of parallel arrangement, ear-picking unit comprises and draws the stem roller, pluck fringe support and rice-pulling chain, draw stem roller front end to be provided with counterrotating in twos spirality fin and import awl, draw stem roller rear axle to the uniform chopping blade that is equiped with, outer cover front end on the ear-picking unit is provided with the nearside divider of parallel arrangement, the power intake of ear-picking unit is connected with each clutch end of integrated gear case, it is characterized in that described chopping blade blade angle is 30～35 °.
Described nearside divider rear portion lower limb and level ground angle are 25～32 °.
The described upper end of stem roller and the frame of drawing is in transmission connection, and drawing stem roller lower end is free end, and drawing stem roll axis and level ground angle is 25～30 °.
The technological progress that the utility model is obtained: (1). owing to draw stem roller rear axle to the uniform chopping blade that is equiped with, and the chopping blade blade angle of interlaced arrangement is 30～35 °, the counterrotating in twos stem roller that draws that is equipped with the chopping blade forms intermeshing bigger coincidence end face when rotated between blade cutting edge, thereby stalk grasp force and lower pulling force are big, and pulling force is stable, the stalk slip rate is low, and fruit ear is reduced the impulsive force of plucking the fringe plate, has reduced the corn ear grain loss.(2). owing to adopt small inclination, it is 25～30 ° that initial established angle promptly draws stem roll axis and level ground angle, nearside divider rear portion lower limb and level ground angle are that the nearside divider straw-distributing angle is 25～32 ° simultaneously, thereby can satisfy the results of low spike position fruit ear and falling corn, improved the corn ear utilization percent.(3). because to draw stem roller lower end is the cantilevered free end, when guaranteeing to draw the stem roller coaxiality, make overall structure simple, install easy to adjustly, thereby reduced Installation and Debugging difficulty of the present utility model and production cost.

Embodiment
For further describing the utility model, the utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1～shown in Figure 6, the utility model comprises the spiral pair roller ear-picking unit of parallel arrangement and is located at the fruit ear conveying screw feeder 1 at ear-picking unit rear portion, ear-picking unit comprises and draws stem roller 2, plucks fringe support 5 and rice-pulling chain 4, the power intake of ear-picking unit is connected with each clutch end of integrated gear case, draw the upper end and the frame of stem roller 2 to be in transmission connection, drawing the lower end of stem roller 2 is free end, draws stem roller 2 axis and level ground angle β
1It is 25～30 °, draw stem roller 2 front ends to bore 7 for counterrotating spirality fin importing in twos, draw the five group chopping blades 6 of stem roller 2 rear axle to the installing interlaced arrangement, counterrotating in twos stem roller 26 formation extractings of blade when rotated, the drop-down and shear action of drawing of chopping blade 6 is installed, and blade 6 blade angle α are 30～35 °; The nearside divider 3 of the front end installing parallel arrangement of the outer cover 10 on the ear-picking unit, as shown in Figure 2, the straw-distributing angle β of this nearside divider 3
2Be 25～32 °, this straw-distributing angle β
2Angle for nearside divider 3 rear portion lower limbs and level ground.
When harvesting corn, combine of the present utility model is installed in the ranks walks along corn, corn stem is imported between the counterrotating importing awl 7 by nearside divider 3, counterrotating importing awl 7 imports the stem stalk and draws the stem groove, the stem stalk is drawn the stem roller 2 that draws on stem groove both sides to draw in two gaps of plucking 9 of fringe plates, fruit ear is taken, and the corn ear of taking is gone into sheller unit after being transported to horizontal screw feeder conveyer under the stirring that imports the dialing-grain unit 8 on the chain 4, and stalk is by drop-down and chopping simultaneously; Along with advancing forward of combine, owing to draw stem roller 2 axis and level ground angle β
1And nearside divider 3 rear portion lower limbs and level ground angle β
2Be that the nearside divider straw-distributing angle is less, thereby low spike position fruit ear and falling corn are also drawn, and the counterrotating chopping blade 6 of stem roller 2 rear portions installing grasp, drop-down and mincing and returning to the field.
