Description

The little grain header of a kind of modified

Technical field:

The utility model relates to a kind of crop cropper, and the little grain header of particularly a kind of modified belongs to the agricultural equipment field.

Background technology:

Along with the development of agricultural activityization, various types of millets, wheat grain header, combine are numerous, but are adapted to hills, mountain region and the less farmland of field piece, have only small harvester can party on purposes.But many small harvesters of Xiao Shouing in use exist some shortcomings and defective because of the structure imperfection in the market, if any grain header have only a ceding of Taiwan, stay cut the stubble too high, be unfavorable for that the back is as crops such as kind of beans, perhaps go up the asynchronous or upper header of lower cutting table and earlier paddy is pushed over, lower cutting table can not carry out perpendicular cuts and paddy can not be cut off; Or too many because of the paddy paddy amount of sending under cutting off, stuck phenomenon takes place; Or because of after the threshing because of air quantity is big inadequately, fail better to make many impurity, weeds to realize cleaning separating with various, grain.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming of prior art, invents a kind of follow-on little grain header.

The utility model is finished by following array structure: A, ceding of Taiwan assembly are made up of upper header and lower cutting table, following knife section (18) on last moving knife (17) on the upper header and the lower cutting table is driven synchronously by last connecting rod (7) and lower link (5) respectively and realizes synchronous cutting; B, installed an axial flow fan vane wheel (23) additional, connected a centrifugal blower (1) in threshing bin (25) outside simultaneously in the end of the critical piece threshing cylinder (24) of threshing assembly; Cage (19) two ends are stirred in C, the conveying in delivery assembly, and spring automatic mechanism (11) is installed.

Lower cutting table in the little grain header of described modified, the following cutter (comprise and decide cutter, following moving cutter down) that it is characterized in that being installed on the lower cutting table frame by angle-adjusting mechanism (6) control, can be made 0 °～15 ° angle adjustment.

The upper cutter of making synchronous cutting (17) of the little grain header of described modified and following moving knife (18), the synchronous structure that it is characterized in that realizing moving is that upper and lower strut (7,5) is fixed on the same vertical pendulum post (8), and is hinged with the eccentric wheel (10) of a rotation with the rocking bar (9) that pendulum post (8) is hinged.

The last moving knife (17) of making synchronous cutting in the little grain header of described modified and following moving knife (18), the synchronous structure that it is characterized in that realizing moving be up and down knife section (17,18) hinged respectively moving connecting rod (16) and under moving connecting rod (15); Going up moving connecting rod (16) is hinged with last draw bar (14); Moving connecting rod (15) is hinged with following draw bar (13) down, when two upper sprocket wheels (26) that connected by chain are done to rotate synchronously with lower sprocket (20), reach moving connecting rod (15) down by moving connecting rod (16) in two draw bars (14,13) drive, swing around last pendulum post (22) and bottom post (21) respectively, reach knife section (18) down so also just driven the upper cutter (17) that links to each other respectively, realize synchronous cutting.

Operation principle: this modified small harvester is the same with other little grain header, is made up of power assembly, crawler travel assembly, ceding of Taiwan assembly, delivery assembly, threshing assembly, and it has carried out the improvement of following aspect:

1), ceding of Taiwan assembly is made up of upper header and lower cutting table, going up on the upper header decides moving knife and the upper cutter assembly forms, and forms power sheet and decide moving knife relative motion realization and cut by deciding moving knife and play knife section assembly down.Go up and decide moving knife and decide moving knife down to be synchronized with the movement, reach synchronous cutting.

A kind of structure that realizes synchronous cutting is: the last connecting rod that is hinged mutually with upper cutter (17) and all be fixed on the same vertical pendulum post with lower link that following moving knife (18) is hinged mutually, be hinged with pendulum post (8), rocking bar (9) is hinged with the eccentric wheel (10) of a rotation, eccentric wheel (10) rotates, driving upper and lower knife section by upper and lower connecting rod again is synchronized with the movement, another structure is: upper and lower knife section is made synchronous cutting by two sprocket wheels of the synchronous rotation of do of chain link through upper and lower draw bar and upper and lower moving connecting rod transmission.

2), the following cutter on the lower cutting table frame (comprise and decide cutter, following moving cutter down) by angle-adjusting mechanism (6) control, can be made 0 °～15 ° angle adjustment.Guarantee to be pushed away before the ceding of Taiwan on the rice bar when tilting with this, still can perpendicular cuts, guarantee to cut off rice stubble, grain header is operated steadily.

3), installed an axial flow fan vane wheel (23) additional in an end of threshing cylinder (24), connected a centrifugal blower (1) in threshing bin (25) outside simultaneously, making has enough wind-force to separate preferably with grain by weeds, and weeds can comparatively fast blow out from grass outlet.

4), stir cage (19) two ends fulcrum in conveying and make adjustablely, adopt spring control, when initial tension of spring hour, the feeding adjustment amount is little, can realize that in a word the rice stubble grass that cuts down stirs cage (19) Shi Buhui and is stuck entering to carry.

Carry out the little grain header of improved the utility model according to technique scheme, owing to adopted synchronous cutting to reach the adjustability of cutter angle down, make grain header operation balance, good cutting effect, can not push over rice stubble and cut continuous phenomenon, can not carry the stuck phenomenon of feeding yet, and weeds and grain preferably, the overwhelming majority can be received the bag of packing into.
