Description
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 agricultural mechanical field.
Background technology:
Present all kinds of millet, wheat grain header, combine are numerous.But be adapted to the hills, the harvesting of mountain region and little field piece has only the small harvester platform to use.Yet many small harvesters on sale in the market in use exist some shortcomings and defective because of the structure imperfection.If any grain header have only a ceding of Taiwan, stay cut the stubble too high, be unfavorable for the sowing of back crop; Perhaps upper and lower ceding of Taiwan cutting is asynchronous; Or upper header earlier pushes over cereal, the lower cutting table cutting that can not be well on; Or preferably cereal is separated with weeds because of failing after the threshing, make many weeds enter collecting bag with grain, cause harvesting quality to descend; What also have can not adjust owing to the lower cutting table height, makes and moves inconvenience when ditch is crossed bank.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned prior art deficiency, invents the synchronous interlock of a kind of employing, has realized upper and lower ceding of Taiwan synchronous cutting; Cleaning fan and recleaner screen are installed in employing additional, reach weeds and realize preferably separating with cereal, and structurally make threshing bin and selected assembly fixed-site, and complete machine is operated steadily; Upper header and lower cutting table are independently controlled, and are convenient to adapt to the little grain header of modified that piece operation of different fields and field are crossed ditch and crossed bank.
The purpose of this utility model is that sad array structure is down finished; The little grain header of modified is made up of power assembly, crawler travel assembly, ceding of Taiwan assembly, delivery assembly, threshing assembly, selected assembly, it is characterized in that:
A, ceding of Taiwan assembly are made up of upper header and lower cutting table, and the following knife section (21) on upper cutter on the upper header (19) and the lower cutting table is driven synchronously by last connecting rod (18,32) and lower link (23) respectively and realizes synchronous cutting.
B, threshing assembly and selected assembly fixed-site; Upper header and joining with it transport tube (13) and threshing bin (1) side-lower fulcrum hinge-coupled, it can under normal circumstances, only do 0 ° of-15 ° of rotation around the upwards 30 ° of rotations of your writing of hinge (11B); Lower cutting table and upper header belong to independently to be controlled.
In C, the selected assembly, recleaner screen (6) and cleaning fan (10) have been increased.
The described upper header of above-mentioned B is controlled by upper header top machine (14); Lower cutting table is controlled by lower cutting table top machine (25).
The described ceding of Taiwan assembly of above-mentioned A, upper cutter (19) are hinged with connecting rod (18), (32), (31) respectively, are controlled by crank (31); Following knife section (21) is hinged with connecting rod (22), (23) respectively, and by crank (9) control, crank (9) and (31) are to move in the same way with speed equally, the existing synchronous cutting of historical facts or anecdotes.
The described cleaning fan of above-mentioned C (10) is positioned at below, threshing bin right side, and air outlet is facing to selected teacher (6) top; Described recleaner screen (6) links with connecting rod (4), (5), (7), when crank (9) rotates, and drivening rod, it is moving that recleaner screen is not stopped.
The little grain header of modified is the same with other little grain header, and it is made up of power assembly, crawler travel assembly, ceding of Taiwan assembly, delivery assembly, threshing assembly, selected 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, last stationary knife and upper cutter assembly on the upper header form; Lower cutting table is formed by following ledger-plate and following knife section assembly, and knife section and ledger-plate relative motion realize cutting, and last moving knife and following moving knife drive the realization synchronous cutting synchronously by last connecting rod and lower link respectively;
2), threshing and selecting device are fixed in the selected assembly, and complete machine is operated steadily; Increase the bigger centrifugal blower (cleaning fan) of power and install a selected vibrating screen additional on collecting box top at the threshing bin side lower part, vibrating screen is driven by fork, and it is moving not stop; The vibrating screen hole can make heavy and little grain falls, and the weeds on the vibrating screen are promptly blown away by the wind that blower fan blows out.
3) upper header and the transport tube that connected can rotate around a fulcrum, can realize the upper header Height Adjustment, when upper header was adjusted to the extreme higher position, upper cutter knife and horizontal sextant angle were 30 ° of angles, in working order, the angle of upper cutter knife and horizontal plane is advisable between 0 °-15 °; Following cutter height overhead can be adjusted separately, is convenient to, hardness and peasant household different require immediately adjustment cutting height soft according to the field piece, guarantees harvesting quality.
The harvesting work flow is as follows: after the grain ear or the wheat head are cut off by upper cutter knife, in ceding of Taiwan case, be transferred and stir cage and send into transport tube, and under the effect of upper and lower two conveying cylinders, rising enters threshing bin, and in threshing bin, through threshing cylinder, the realization threshing of tempering, grain after the threshing or wheat drop on the selected vibrating screen through a threshing scalping, fall again and enter in the collecting box, and weeds can not fall from selected vibrating screen after falling, and are blown away by stronger wind, and blow out from grass outlet; Cut the stubble that cuts than length of the grain ear or the wheat head, the following cutter that is highly mixed up cuts off and falls to lying in Tanaka.
According to the improved little grain header of technique scheme, owing to adopted synchronous cutting, and make upper cutter knife and following cutter adjust to suitable angle and height independently, feasible harvesting operates steadily, adapt to multiple plot and various operation, good cutting effect, installed selected vibrating screen and cleaning fan additional after, the selected effect of each thing is improved greatly, and weeds can not sneaked in the collecting box.
