Description

Combine with walking tractor matching

The utility model relates to a kind of combine, particularly relate to a kind of small-sized, light, be suitable for the knob that use with combine walking tractor matching.

As everyone knows, combine is a kind of comprehensive crop cropper tool that integrates harvesting, threshing, although its structure and form and different, its basic structure all comprises climbs standing grain device, rice cutter, send standing grain device, conveying mechanism and thrasher.Large-scale combine begins to use already, but because it is bulky, and structure and complicated operation cost an arm and a leg and can not be that common peasant household buys and uses.This in addition big machinery also is difficult in the mountain area and use the knob.With regard to small-sized agricultural activity, the most often hand tractor of use, but with the combine of walking tractor matching seldom, and be suitable for just more difficult the seeing that use mountain area and knob.For this reason, the applicant discloses in utility model patent 992368847 a kind of " with the combine of walking tractor matching ", and this grain header can be finished from gathering in whole work of threshing, has practical effect preferably.But still there is certain defective in design in this machine, mainly shows, its thrasher is arranged at the exit, top of conveying mechanism, has so just blocked the sight line of human pilot, makes its harvesting situation that can't see the place ahead clearly, thereby influences harvesting quality and efficient.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of more convenient to operate flexibly performance is more reliable and provide, harvesting efficiency higher with combine walking tractor matching.

For achieving the above object, the utility model provides a kind of and combine walking tractor matching, this combine comprise climb standing grain device 1, rice cutter 2, send standing grain device 3, conveying mechanism 4 and thrasher 5, the described standing grain device 1 of climbing flexibly connects by two pull bars 11 and rack of standing grain-feeding device 31, and adopt belt gears 13 transmissions with being contained in the spiral-wound roll sent in the standing grain frame 32, be connected with the adjusting rod 12 that standing grain device height is climbed in an adjusting on the above-mentioned pull bar; Described rice cutter 2 comprises rice crop-cutter 21 and secondary rice crop-cutter 22, wherein rice crop-cutter is contained in the front end of rack of standing grain-feeding device 3, the secondary rice crop-cutter be contained in be contained in the connecting rod that rack of standing grain-feeding device 31 links to each other on, they link to each other with power transmission shaft 6 by the swing mechanism 23 of one side; The described rear end of standing grain device 3 and the transmission case 7 of sending is affixed, and adopts sprocket wheel chain mechanism driving with power transmission shaft 6; Described conveying mechanism 4 is contained in and send between standing grain device and the thrasher, the one end is connected in the exit of sending the standing grain device, the other end is connected in the porch of thrasher 5, this end bottom is supported on the tractor fuselage with support bar 41, its drive sprocket is contained on the power transmission shaft 6 of conveyer belt bottom, the elevating mechanism 8 of a control rice cutter 2 and conveying mechanism 4 liftings is housed in the tractor front portion, it is characterized in that, described thrasher 5 is contained in the exit of the downward-sloping slideway 51 of conveying mechanism, its shell is fixed on the gear box of tractor bonnet, it and power transmission shaft 6 adopt belt transmission, be connected with a grain conveyer belt 10 at the thrasher port of export by chain gear transmission, it extends to tractor driver obliquely upward the side, and its exit is with grain catcher.

A plurality of " L " shape scraper plate 101 is housed on the described grain conveyer belt 10 at interval.

As shown from the above technical solution, the utility model combines combine with hand tractor, realized the miniaturization of combine, thereby not only greatly reduce production cost, make it and to be bought and use by common peasant household, and, thereby can carry out operation in the farmland of relatively poor mountain area of the landform of plow harrow operation and knob at hand tractor because its volume is little, can solve these areas can't be with the problem of mechanized harvest.Because it comprises that parts such as sending standing grain device, thrasher all are contained in the tractor bottom, thereby has not only reduced center of gravity, and makes human pilot the place ahead not have any shelter, makes its visual field openr, the operation of being more convenient for, thereby can more effectively improve harvesting efficiency.The utility model has not only been realized the supporting of combine and hand tractor, and have simple and compact for structure, flexible and convenient operation, dependable performance, produce and operating cost low, characteristics such as easy to maintenance, thereby have bigger promotional value.
