Abstract

The utility model relates to a small combine harvester which is driven by a tractor of from 25 to 30 horsepower. A header is hung at the front part of the tractor, a threshing device is hung at the stern of the tractor, and the front and the rear parts are connected by a conveying device. The utility model adopts novel structures to improve wording property. The small combine harvester adopts a waste recycling rethreshing mechanism to reduce threshing loss, a long segment cleaning sieve which uses the cleaning mode of first sieving dust and then sucking case to improve cleaning rate of more than 99.5 % and to reduce pollution, a cleaning sucking fan and a roller which are coaxial to simplify structure and a soybean flexible low-cutting device to reduce the header loss for harvesting soybean, and a grass anti-winding wheel device is arranged in a middle belt conveying device.

Description

Baby combine

The utility model belongs to the technical field of agriculture field combine.

Current, rise baby combine heat in the whole nation, the producer that starts is a lot, but really suitable seldom welcome, mainly has following defective:

1, owing to put undue emphasis on and fraction horsepower tractor (as 12 horsepowers, 15 horsepowers, 18 horsepowers), the excessive miniaturization of parts causes dependability poor, and fault is many, and maintenance time is long, and the actual job time is short.

2, in order to reduce power consumption, adopt and do not have sieve selection by winnowing or simple and easy sieve selection by winnowing, the grain clean rate is low, generally between 95-97%, so still need winnow or special machinery is cleaned.

3, also be for the minimizing machine is heavy, reduce power consumption, be not with assorted surplus recovery rethreshing device, so just increased the threshing loss.

The purpose of this utility model is a kind of baby combine of design, adapt to farm agricultural machinery specialist of current rural households needs, it and 25-30 horsepower tractor, it is few to have fault, reliability height, band rethreshing device, the threshing loss is few, dressing mechanism uniqueness, thereby grain clean rate height (＞99%) have also reduced environmental pollution.In order to reduce characteristics such as the ceding of Taiwan loss of soybean, band soybean flexible lower cutting installation.

The utility model is walking and operation power with the tractor, forms by the ceding of Taiwan, thresher and conveyer three parts in addition, and the anterior header part that hangs of tractor, tractor rear hangs the thresher part, and the centre is coupled together front and back two parts by conveyer.

Header part mainly contains: compositions such as nearside divider, ceding of Taiwan screw feeder, ceding of Taiwan hanger bracket, cutter, straw shift wheel.In order to reduce the ceding of Taiwan loss of harvesting soybean, other is furnished with flexible lower cutting installation.The soybean flexible lower cutting installation is made up of suspension rod assembling, pull bar assembling, the assembling of cutter head roller slideway, cutter head extension spring, the assembling of cutter head roller, the assembling of cutter head case, nearside divider, the seam of cutter head block, cutter, the sliding palm of cutter head, transiting rod, leaf spring etc.

Thresher part mainly by thresher hanger bracket, frame, cylinder, notch board, long segmentation sorting screen, clean blower fan, assorted surplus lifter, tailing auger, Da Gai, connect grain mouth etc. and form.

The structure of long segmentation sorting screen is: first section is the aperture wire gauze sieve, and second section be that iron plate round-hole mesh, the 3rd section are the macropore wire gauze sieve.

Middle conveyer adopts belt to inlay the rake teeth structure.At the other anti-grass wheel that twines that adds of driving wheel, the anti-grass wheel outer rim that twines studs with three cuttves, and its rotating speed and driving wheel speed ratio are 2: 1.When two-wheeled rotated in the same way, the official post cutter of speed produced cut-out power to the grass that twines of driving wheel, thereby the grass that twines on the driving wheel is in time cut off.

The utility model has adopted assorted surplus recovery Rethresher structure, has reduced and has carried button mistake, threshing performance height secretly; Adopt long segmentation sorting screen to clean the mode of cleaning of sieve ash back suction shell earlier, clean rate is improved greatly, can reach 99.5%, reduced environmental pollution; Adopted the soybean flexible lower cutting installation to reduce ceding of Taiwan loss, the cutting amount of floating is 80mm, and close mowing is recommended and is 40mm; The anti-grass wheel that twines is set on the intermediate belt conveyer, can cuts off twining grass, avoided the belt rake teeth and made rake teeth and cylinder spike-tooth interfere the destruction that collision causes owing to twine grass; Owing to adopted tractor to drive than high-power, make structure more reasonable, operating efficiency is higher.

Fig. 1 is a front view of the present utility model, shows its general structure;

Fig. 2 is the left view of thresher part;

Fig. 3 is the front view of soybean flexible lower cutting installation.

Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described

This machine is driven by 25 or 30 horsepowers tractor; by ceding of Taiwan link 6 ceding of Taiwan is connected with the tractor front end; by threshing hanger bracket 17 the thresher part is connected machine when advancing operation with tractor rear; divide woodenware 1 cutting the inside and outside crop in district separately; straw shift wheel 2 is guided the crop of needs results into cutter 3; crop after cutting off; in its deadweight; swing to the ceding of Taiwan 5 equably under the pace of grain header and the synergy of straw shift wheel; ceding of Taiwan screw feeder 4 is transported to right-hand member to crop; the expansion link of screw feeder right-hand member and rubbing board are installed with the anti-grass wheel 18 that twines with the crop middle conveyer 7 of pulling in middle conveyor belt driving wheel one side.Crop is sent into thresher at middle conveyer under the pressure holding of tooth; under threshing cylinder 9 and the 8 guide plate synergy of big lid, do circular motion and axially-movable; the crop cane is shifted to left end from the right-hand member of cylinder; under the effect of centrifugal force and Lysimachia sikokiana plate; cane is by outside the straw outlet 13 discharge machines; crop is in the process of motion; be subjected to the cylinder spike-tooth; (hit under the synergy of notch board 10; collide; curry); emersion object falls from the concave grate hole; fall on long segmentation sorting screen 12; along with the shake of sieve, dust sifts out from the aperture wire gauze sieve, falls on the ground; grain husk shell and seed; beans folders (wheat head) are when the inlet scoop; the grain husk shell is picked up by cleaning outside the blower fan 11 discharge machines, and seed falls from round-hole mesh, passes through bag by connecing 14 collections of grain mouth.Beans folders (wheat head) fall by slide plate from griddle and drop to 15 li of lifters, and the lifter scraper plate is sent to 16 li of tailing augers, and tailing auger is sent beans folders (wheat head) into cylinder and taken off again, and whole harvesting threshing course is all finished.

As shown in Figure 3, be the soybean flexible lower cutting installation.Before the harvesting soybean, nearside divider among Fig. 11, cutter 3 are unloaded, the soybean flexible lower cutting installation is suspended on A, B 2 points (double dot dash line is the ceding of Taiwan) of the ceding of Taiwan, during the harvesting soybean, the sliding palm 20 of cutter head is close to the ridge platform, cutter 29 is under the effect of leaf spring 32 when vertical ground is uneven, with the profiling that fluctuates of the sliding palm 20 of cutter head; When horizontal ground was uneven, cutter 29 was under the synergy of the strain of cutter band steel beam and leaf spring 32 and the profiling that fluctuates, and cutter 29 is close to ridge platform operation like this, has realized that the low stubble of soybean gathers in, and has reduced field loss.

The structure of soybean flexible lower cutting installation is formed to be had: derrick rig 21, pull bar assembling 22, cutter head roller slideway assembling 23, cutter head extension spring 24, cutter head roller assembling 25, cutter head case assembling 26, nearside divider 27, cutter head block seam 28, cut 29, cutter head slidingly slaps 30, transiting rod 31, leaf spring 32.
