Abstract

The utility model discloses a dust removal device for a combine harvester, which consists of a header arranged on the front of the harvester, a threshing part, an engine, a running part, a grain bin and a bridge. A dust-removing pipe is arranged between the lean feed room casing of the header and the blower of the threshing part. A scale screen filter screen is arranged on a connecting part between the dust-removing pipe and the lean feed room. The dust-removing pipe can be arranged both outside and inside. With the connection of the dust-removing pipe and the wind power from the exhaustion of the blower, the dust is exhausted and driven to the back part of the harvester, which avoid that the dust is exhausted from the front mouth of the lean feed room to the front part of the harvester; the clear vision of a driver is ensured; the damage to the body is avoided; the service life of the engine is prolonged; the structure is simple; the dust-removing problem can be solved without big change on the harvester and the utility model is easy to be popularized.

Description

The combining dust removal device

(1) technical field

The utility model relates to a kind of agricultural machinery, relates in particular to a kind of dust arrester of combine.

(2) technical background:

Development along with agricultural economy, improving constantly of level of farming mechanization, utilize combine to replace the trend that original reaping hook formula carries out the harvesting of crops has been become agricultural development, present combine is of a great variety, also be not quite similar at different crops structures, utilizing maximum then is combining to wheat, and this type of combine essential structure comprises straw shift wheel, cutter, ceding of Taiwan screw feeder, carry chain harrow, notch board, drum with rasp bars, by the wormwood artemisia wheel, shuttle board, blower fan, top sieve, rethresher, following sieve, straw separator, check apron, the grain elevator, unloading screw conveyor; This class combine integrates harvesting, threshing, separates, cleans, and fuselage is little, compact conformation, and running is convenient, and flexible operation because applying of this type of combine improves harvesting efficiency greatly, reduces labour intensity.But the shortcoming of the maximum of this type of combine is: when body moves, because the dust that institute's body takes up flies upward by being positioned at the coupled conveying chain harrow barrel-type casing ejection in front, the result, make the driver who is sitting on the bridge fill the air operation under the environment of very severe at dust, the driver does not almost see the direction of advancing, and only advances with feeling, a class gets off, the driver has almost become natives, thereby diminishes the healthy of driver greatly; Simultaneously, a large amount of dust is blown in the engine and the infringement engine.

(3) summary of the invention

Problem to be solved in the utility model is: exist the problem in service life that a large amount of dirt flew upward, influenced pilot's line of vision, diminish driver's healthy and engine in the combine front portion; The technical solution of the utility model realizes in the following manner: a kind of combining dust removal device, it is made up of the header that is positioned at machine the place ahead, shelling part, engine, running gear, tanker, several parts of bridge, wherein feed between housing and the shelling blower fan partly in header inclination partly and establish a sweep-up pipe, sweep-up pipe and inclination feed chamber interface are provided with lip(ped) sieve sheet filter screen.

Sweep-up pipe can be external, also can be built-in.

The sweep-up pipe front end is connected with a sediment bowl with the precipitation dust.

Good effect of the present utility model is: by the connection of sweep-up pipe, utilize the wind-force of blower fan air draft make dust backward the row of operation to the rear portion of machine, avoid dust to discharge to the place ahead of machine from the prosopyle of inclination feed chamber, assurance driver's sight line is clear and health is avoided damaging and prolong the service life of engine, simple in structure, need not carry out big change to machine and can solve dirt problems, thereby be easy to promote the use of.

(4) description of drawings

The figure accompanying drawing is a structural principle schematic diagram of the present utility model.

(5) embodiment

The utility model is described in further detail for the knot accompanying drawing below, by accompanying drawing as can be seen, the utility model is made up of the header that is positioned at machine the place ahead, shelling part, engine, running gear, tanker, several parts of bridge, header is positioned at the place ahead of machine, partly become with shelling " T " type configuration, it comprises in the feed chamber, feed chamber of the cutter 2 of the crop that top straw shift wheel 1, cutting straw shift wheel are dialled, the ceding of Taiwan screw feeder 3 that is used for feeding crop, the inclination that is connected with ceding of Taiwan screw feeder and is fixed with conveying chain harrow 4; Shelling comprises that partly the cylinder 6 that is connected with the feed chamber outlet is used for carrying out threshing, be fixed with the notch board 5 in band glazing bar hole below the cylinder, notch board 5 belows are provided with shuttle board 8 and are used for receiving seed and clever chaff and the broken cane that falls from notch board 5 glazing bar holes, notch board 5 rears are fixed with straw separator 13 and are used for receiving by the long shoot bar under the throwing by wormwood artemisia wheel 7 of its top and excrete, by being provided with retaining wormwood artemisia plate 14 behind the wormwood artemisia wheel 7, shuttle board 8 tail sheet bars below is provided with top sieve 10, sieve 12 seeds that are used for receiving through shuttle board 8 tail sheet bars whereabouts down, the grain husk chaff, with broken cane, at top sieve 10, sieve the place ahead of 12 down and be fixed with blower fan 9 so that at clever chaff, broken cane is passing through top sieve, being blown to four winds in the following sieve process, it is external to blow out, and following sieve 12 rear portions are fixed with Rethresher 11 and carry out the secondary threshing and send back on the shuttle board together with clever shell then again and further clean to receive by the clean seed that do not take off that sieves down that the rear portion sieve aperture falls; Be connected with slide plate, seed screw feeder in turn and rising moving device 15 below two sieves up and down so that clean seed is transported to tanker; By accompanying drawing as can be seen, on header partly tilts the housing wall of feed chamber, have and connect a sweep-up pipe 16 on hole, this hole, this sweep-up pipe other end is connected with blower fan 9 air inlets of shelling part, sweep-up pipe and inclination feed chamber housing interface are provided with lip(ped) sieve sheet filter screen 17, connection through this sweep-up pipe, make and adsorbed also discharge backward by blower fan, thereby guarantee the sanitation and hygiene of the clear and engine in body the place ahead from the dust of inclination feed chamber ejection.
