Description
Technical field
The utility model is related to harvester engine cooling system dust arrester technical field, more particularly to a kind of rotary
Dust arrester.
Background technology
Dust arrester in grain combine engine cooling system is varied, in severe operating environment,
Occur that clever chaff impurity blocks dust arrester outer net or clever chaff impurity enters blocking radiator inside dust arrester by mesh
The situation of core.Once blocking, air can not effectively circulate, and the heat that coolant is taken away from engine can not just dissipate in time
Fall, so that cause engine high-temperature, combustion deterioration.The service life of engine had so both been influenceed, user has also been forced in operation
Frequently parking cleaning, has a strong impact on operating efficiency and income in journey.
The dust arrester that current harvester is installed is roughly divided into rotary dust arrester and upper air formula dust arrester two
Type, is briefly described to the dust arrester of both types below.
A kind of rotary dust arrester makes dedusting by engine crankshaft front end belt pulley input power using belt transmission
Cover rotation, dust suction tube assembly is arranged in dust excluding hood outer peripheral face.Because dust excluding hood appearance and size is larger, and material is perforated sheet,
In manufacturing process and transport process, it is impossible to ensure its due circularity, namely in dust excluding hood rotary course, outer circumference surface is with inhaling
The distance of dirt pipe is suddenly big or suddenly small, it is impossible to ensure 2~5mm distance, and dust removing effects are undesirable.
Also a kind of rotary dust arrester is by engine crankshaft front end belt pulley input power, using belt transmission
Rotate dust excluding hood, dust suction tube assembly is arranged in apart from 2~5mm of dust excluding hood outer circumference surface position, and sweep-up pipe is answered with harvester
De- device connection.During harvester operation rotates, rotate to form suction using the blade in rethresher, reach to dust excluding hood week
The effect that the weeds of circle and end face are removed., need to be to rethresher because dedusting need to rotate the suction to be formed by rethresher intra vane
Transformed, high is required to rethresher and pick-up performance matching degree, cost is higher.
Upper air formula dust arrester is made up of the dust excluding hood of upper bands mesh and the wind scooper of bottom, and principle is：Make dedusting
The air that device air inlet becomes cloudy away from harvester bottom by operation, cleaner air passes through near the dust excluding hood of top
Mesh enters inside dust excluding hood, by radiator core body, takes away the heat in coolant, so enters as far as possible few dust
Radiator core, reduces the probability that impurity blocks water tank.Principle enters as far as possible few dust to avoid the air of muddiness as far as possible
To water tank.During harvester operation, environment is quite severe, and dust arrester Inlet Position only has enough high effects just enough ideals, but remove
Dust hood is too high will influence complete machine by property, be so not only restricted the size with mesh dust excluding hood, influence cooling is empty
Throughput, and intake swirl can be caused in wind scooper, scattered radiating effect is declined to a great extent.
Utility model content
Technical problem to be solved in the utility model is：A kind of rotary dust arrester is provided, the dust arrester is solved
Harvester engine radiating dust removal problem.

As an improvement mode, the dust excluding hood installed by internal support rotary mechanism and the frame member,
The internal support rotary mechanism includes a pivot, described to be pivotally secured to the framework, and the dust excluding hood is turned by bearing
Dynamic to be installed on the pivot, the arc bent plate is fixed on the pivot.
As an improvement mode, pivot is fixedly mounted in the framework, and the dedusting cover body passes through with the pivot
Bearing rotates connection, and the inner peripheral surface of the dust excluding hood is installed with supporting wheel hub, and the supporting wheel hub passes through with the pivot
Bearing rotates connection.
As an improvement mode, the dust excluding hood is provided with hairbrush close to one end border edge of the framework, institute
State and elastic sealing element is provided between dust excluding hood and the hairbrush.
As an improvement mode, the dedusting box sidepiece is provided with hairbrush.
As an improvement mode, the dust excluding hood is connected with transmission mechanism, and the transmission mechanism includes a transmission
Axle, one end of the power transmission shaft is drive end, and the other end of the power transmission shaft is driven end, the driven end and the dust excluding hood
Drive connection.
As an improvement mode, the drive end of the power transmission shaft is provided with driving pulley, the driven end of the power transmission shaft
Provided with driven pulley, the driven pulley is connected with the dust excluding hood by belt transmission.
Use the technique effect acquired by above-mentioned technical proposal for：
The dust arrester is arranged at the inlet side of radiator, and the fan of radiator air side, which is rotated, can make the inlet side of radiating
Suction is produced, when the clever chaff of weeds of the absorption on the outside of dust excluding hood is rotated to arc bent plate, wind is stopped by arc bent plate,
Wind-force reduces, and weeds grain husk chaff can automatically fall into dedusting box, it is to avoid enter inside dust excluding hood, makes enough clean air by radiating
Device, prevents impurity from blocking radiator core, so as to play good dust removing effects.Applicability of the dust arrester on harvester
By force, dust removal performance is high, and radiating dust pelletizing system maintenance period shortens, and greatlys save the maintenance time of user, improves efficiency of crop,
Reduce cost.
Because the dedusting box bottom connects deep bead, the passage that the clever chaff of weeds drops downwards is extended, it is to avoid drop
Weeds grain husk chaff is returned by air-flow again is drawn onto dust excluding hood surface.
Because the dust excluding hood is close to one end border edge setting hairbrush of the framework, the dust excluding hood and the hairbrush
Between be provided with elastic sealing element, can prevent gap of the clever chaff of weeds between dust excluding hood and hairbrush from entering the radiator that results in blockage
Core.
Because the dedusting box sidepiece is provided with hairbrush, hairbrush is contacted with wire side outside dust excluding hood all the time, in dust arrester work
During work, the clever chaff of the weeds not dropped can be cleared away in time.
