Abstract
The utility model discloses a flexible comb-teeth cylinder used for a stripping combine harvester, which comprises a lower roller shaft and an upper roller shaft that can move up and down each other, a flexible band with a ring member sleeved at the outer circumference of the upper and lower roller shaft. The utility model has the advantages of simple and compact design, good working quality, lower loss rate of seed, less failure, easy regulation and wide application range. The utility model can be arranged at all kinds of stripping combine harvester.
Description
Technical field
The utility model belongs to the operating assembly on the combining facility, is mainly used in the preceding results of cutting of paddy rice and wheat crops.
Background technology
Threshing prior to cutting is a kind of new results agronomic technique that occurs in the agricultural production in recent years, it is when crop stand on the soil, only the crop kernel comb is taken off by broach harvesting mode and to send in the combined harvester, and cane does not enter in the combined harvester, cane or still stand in the field, or the seed comb cuts after taking off and is laid in the field.Because this technology cane do not enter in the grain header, crop is evenly distributed etc. all multifactorly in the field in addition, and this agricultural method seed rate of recovery is than traditional threshing height, and power consumption is little, and the threshing load evenly.But the hackle drum that mates in the combined harvester at home and abroad all is rigid structures at present, and the diameter of cylinder size is big, rotating speed is low, centrifugal force is little, and the seed loss is big, and it is less to promote face so far.In order to overcome the above-mentioned shortcoming of rigidity hackle drum, the induced-draught fan of on combined harvester, having set up special-purpose grain suction that has, not only configured in one piece difficulty, and structure is very complicated, and consumed power increases, and costs an arm and a leg.The applicant had once studied a kind of flexible hackle drum of the three-axis structure that supports rolling bar that has, and its transaction capabilities is good, but its structure still shows complexity, and the overall structure size is bigger than normal.
Summary of the invention
The purpose of this utility model is exactly technical problem and the defective at rigidity hackle drum and the flexible hackle drum existence of three-axis structure; design provides a kind of novel threshing prior to cutting combined harvester flexible hackle drum; reach and simplify the broach threshing structure, improve the broach results seed rate of recovery, reduce the purpose of losing, guaranteeing operation quality, reduce power consumption.
Basic design of the present utility model is, the bottom roller axle is fitted in the upper roller shaft below, and all can move up and down relatively between bottom roller axle and the upper roller shaft, and flexible band is sleeved on active roller and the following active roller outer circumference surface, and whole cross section is shape ringwise.
The utility model has overcome the shortcoming of rigidity hackle drum and the flexible hackle drum of three-axis structure, have simple in structure, volume is little, broach harvest operation quality is good, the seed percent of loss is low, fault is few, easy to adjust, characteristics that application is wide, can be fitted on the facility of results before various the cutting.
Description of drawings
Fig. 1 is the flexible hackle drum general structure of a threshing prior to cutting combined harvester schematic diagram;
Fig. 2 is the dextrad view of Fig. 1.
Piece number explanation among the figure:
1, goes up active roller, 2, upper roller shaft, 3, upper belt pulley, 4, flexible band, 5, broach, 6, bottom roller axle, 7, following belt pulley, 8, following active roller.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The flexible hackle drum of threshing prior to cutting combined harvester comprises the bottom roller axle 6 that is installing the upper roller shaft 2 of going up active roller 1, upper belt pulley 3 and installing active roller 8, following belt pulley 7, and the flexibility of equipped uniform arrangement broach 5 is with 4, bottom roller axle 6 is fitted in upper roller shaft 2 belows, and all can move up and down relatively between bottom roller axle 6 and the upper roller shaft 2, flexibility is with 4 to be sleeved on active roller 1 and following active roller 8 outer circumference surfaces, and whole cross section is shape ringwise.
When operation is used; this flexible hackle drum is fitted on the combined harvester that cuts preceding results; utilize driving belt with the transmission system of reaping machine respectively with last; following belt pulley 3; 7 connect; flexibility is with 4 last; following active roller 1; 8 drive down; annular flexible band 4 is around last; bottom roller axle 2; 6 axial lines rotate; when broach 5 inserts in the cane and moves upward, rice or wheat head head are taken off from cane top comb; on moving to during active roller 1 angle position place; owing to have big angular speed and produce big centrifugal force, rice or wheat head head and seed are thrown in the separating mechanism of combined harvester.Bottom roller axle 6 or upper roller shaft 2 are moved up and down its axle base of adjusting, realize the adjustment of flexibility with 4 rates of tension guaranteed broach operation quality and effect.Upper and lower roller shaft 2,6 all has the dual-use function and the effect of driving wheel and regulating wheel.
Claims (1)
