Abstract

Disclosed are a lifting device used for a combine in agricultural machinery to remove the impurities in crops during the operating process, and an alarm device used when an auger and a lifter go wrong. The crop pressure lifting device of the combine can effectively solve the problems that during the working process of the combine, seeds, mud, gravel, carpolite and other impurities are mixed in the soybeans, and the auger and the lifter can easily result in grain breaking, blocking and losing, so that the grain loss rate is high and an alarm can not be timely given when the auger and the lifter conk out. In the utility model, a wind duct is arranged on a closed separating bin and connected with a draft fan; a grain channel and a colloid grain outlet are arranged below the closed separating bin; therefore, the closed separating bin, the wind duct and the draft fan are communicated with each other; at the same time, the grain channel and the colloid grain outlet are communicated with the closed separating bin; the vanes of the draft fan are arranged inside the draft fan; the draft fan is fixed on a mounting bracket and arranged on the combine through the joint position.

Description

Cereal pressure intensity hoisting device of combine-harvester

Technical field

The utility model is in the agricultural machinery, and combine is in use removed the lifting device of impurity in the crop, and the warning device that breaks down of auger and elevator.

Background technology

The cereal of the present combine part of putting in storage, rely on rake formula or drag-flight elvator, when the harvesting soybean, can't solve that seed is stained with mud and and impurity such as soil block, stone ooze the problem of hybridization in soybean, and pushing auger and elevator very easily produces grain crusher and obstruction and runs grain, grain loss rate height, the shortcoming that auger and elevator break down and can not in time report to the police.

Summary of the invention

The purpose of this utility model: in order to overcome this type of problem that existing combine exists, the utility model provides a kind of combine cereal to promote and warning device, and this device can solve the problem of oozing assorted impurity in the cereal and mechanical disorder and the loss that causes effectively.

The utility model is that the technical scheme that its technical problem of solution is adopted is: the air-introduced machine rotation produces negative pressure, air-flow from bottom to top, the crop of results enters in the airtight separation bin along the air channel and scatters, and the heavy impurity of quality falls naturally, and the impurity of light weight is discharged through blower fan with air-flow.When grain when grain inlet stops up, grain drops down onto in the bucket, when grain during in fast expiring, contact with electronic inductor, at once warning; When filling, the heavy impurity of the quality such as stone that receive also reports to the police at once.

The beneficial effects of the utility model are: reduce the broken seed of operation, avoided the foundry loam grain, soil block, dust, stone ooze the shortcoming in the coarse cereals; Overcome auger, elevator is blocked and the shortcoming that breaks down and can not in time report to the police, has reduced the loss of grain.

Description of drawings

Figure is the cereal pressure intensity hoisting device of combine-harvester structural representation.

Among the figure: 1, prolong mouthful 2, grain inlet, 3, the cereal passage, 4, the colloid mouth of putting out cereal, 5, airtight separation bin, 6, the air channel, 7, wind-force adjusts valve, 8, air-introduced machine, 9, the air-introduced machine blade, 10, mounting bracket, 11, the joint; 12, the antifouling police's bucket of failing to report; 13, electronic inductor.

Embodiment

Air channel 6 is installed on airtight separation bin 5, and air channel 6 links with air-introduced machine 8, and airtight separation bin 5 belows are that cereal passage 3 and colloid put out cereal mouthfuls 4, therefore, airtight separation bin 5, air channel 6, air-introduced machine 8 communicate, and simultaneously, cereal passage 3 and colloid are put out cereal and mouthfuls 4 also communicated with airtight separation bin; Air-introduced machine blade 9 is installed in the air-introduced machine 8, and air-introduced machine 8 is fixed on the mounting bracket 10 and is installed on the combine by joint 11.Antifouling alarm 12 and electronic inductor are installed below grain inlet 2.When engine operation, drive air-introduced machine 8 belt pulley work, air-introduced machine blade 9 (designing specific angle) rotates as schemes (the quantity angle is not marked) by the working speed of engine, makes air channel 6 produce negative pressure.Airtight separation bin 5 also produces negative pressure simultaneously, the material behavior of mouth 4 because colloid is put out cereal, close this moment, air-flow is from bottom to top by prolonging mouthful 1 when entering through grain inlet 2, auger in the work (not mark) is pushed into grain inlet 2 with grain, grain rises in cereal passage 3 in the airtight separation bin 5 with air-flow and scatters, falling puts out cereal through colloid mouthfuls 4 enters silo, (can adjust as required) soil block, stone are then prolonging a mouthful whereabouts, 1 place under the control of wind-force adjustment valve 7, the foreign material that proportion is lighter, dust etc. are discharged through air-introduced machine 8 with air-flow.

Setting antifouling, that fail to report alert bucket 12 is that grain drops down onto in the bucket when grain stops up at grain inlet 2 places, when grain is expired soon, contacts with electronic inductor 13, reports to the police at once; Second function antifouling, that fail to report alert bucket 12, electronic inductor 13 is that stone, the soil block that receives filled, and also reports to the police at once.

Claims

A kind of cereal pressure intensity hoisting device of combine-harvester, it is characterized in that going up installation air channel (6) at airtight separation bin (5), air channel (6) links with air-introduced machine (8), airtight separation bin (5) below is cereal passage (3) and the colloid mouth (4) of putting out cereal, air-introduced machine blade (9) is installed in the air-introduced machine (8), and air-introduced machine (8) is fixed on mounting bracket (10) and upward is installed on the combine by joint (11); In the below of grain inlet (2) antifouling alarm (12) and electronic inductor are installed.
