Detailed Description

The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without any creative work based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in fig. 1 to 2, the exhaust treatment device for the agricultural machinery, which is convenient to install, comprises a treatment tank 1, a filter element assembly 2, a scraping brush assembly 3, a connecting hoop 4, a supporting hoop 5 and a telescopic rod 6.

Referring to fig. 1, a basic structure in which the filter element assembly 2 is disposed inside a treatment tank 1 and an air inlet and an air outlet are respectively formed at both ends of the treatment tank 1 is commonly used in the conventional structure.

In order to be convenient for being tightly connected with the end part of the agricultural machine exhaust pipe 7, a hose connector 1-4 is fixedly communicated with an air inlet of a treatment tank 1, and the hose connector 1-4 is sleeved on the end part of the agricultural machine exhaust pipe 7 and then is fastened through a connecting fastening hoop 4.

Because the end part of the agricultural machine exhaust pipe 7 is in a bent form, the treatment tank 1 is also inclined after being installed, which is not beneficial to the stability of the treatment tank 1, therefore, the supporting clamping ring 5 is fastened below the end part of the agricultural machine exhaust pipe 7, and the telescopic rod 6 is obliquely supported between the bottom of the treatment tank 1 and the supporting clamping ring 5. The upper end and the lower end of the telescopic rod 6 are respectively hinged with the bottom of the treatment tank 1 and the edge of the supporting fastening ring 5, so that the angle can be conveniently adjusted and installed. The telescopic rod 6 comprises an inner rod and an outer tube which are mutually sleeved, a screw hole is formed in the tube wall of the outer tube, a jackscrew is screwed on the tube wall of the outer tube, the inner rod and the outer tube are tightly fixed, and other structures with telescopic locking can be adopted for replacement.

In order to facilitate the installation, the replacement and the cleaning of the internal filter element assembly 2, the treatment tank 1 is provided with a detachable cover 1-1, the cover 1-1 and the treatment tank 1 can be fixed by bolts with one hinged end and the other end, or can adopt a detachable connection mode with two ends respectively fixed by bolts, the two modes are only simple examples, and other similar detachable structures naturally belong to the protection range of the application, such as conventional detachable replacement modes of lock catch fixation, interference clamping and the like.

Referring to fig. 2, in order to make the best of the vibration of the engine, the scraping brush assembly 3 is additionally arranged in the treatment tank 1 close to the filter element assembly 2, specifically, the sealing cover 1-1 is obtained by cutting the upper half part of the middle position of the treatment tank 1, semi-annular lattice blocking sheets are respectively machined on the inner wall of the sealing cover 1-1 and the corresponding position of the inner wall of the treatment tank 1 at intervals along the axial direction, and at least one filter element accommodating cavity 1-2 and a scraping brush accommodating cavity 1-3 adjacent to the filter element accommodating cavity are separated from the interior of the treatment tank 1.

Since the filter element assembly 2 mainly concentrates the particles obstructed by filtration on the air inlet side, that is, the side of the filter element accommodating chamber 1-2 adjacent to the hose connector 1-4, it is preferable that the wiper accommodating chamber 1-3 is also provided on the side of the corresponding filter element accommodating chamber 1-2 adjacent to the hose connector 1-4.

The filter element accommodating cavity 1-2 is internally and tightly plugged with the filter element assembly 2, the scraping brush accommodating cavity 1-3 is internally and movably provided with the scraping brush assembly 3, so that when engine vibration is transmitted to the agricultural machine exhaust pipe 7, the scraping brush assembly 3 can also vibrate in the scraping brush accommodating cavity 1-3. The wiper assembly 3 is a circular grid plate and is provided with bristles 3-1 on one side, and the structure can allow the exhaust gas to pass through. Specifically, the diameter of the scraping and brushing component 3 is larger than the diameter of the inner ring of the semi-annular grid separation blade, and is smaller than the diameter of the scraping and brushing accommodating cavity 1-3, so that the scraping and brushing component 3 can vibrate in the scraping and brushing accommodating cavity 1-3, and can not break away from the scraping and brushing accommodating cavity 1-3 to enter the inner ring in butt joint of the two semi-annular grid separation blades between the sealing cover 1-1 and the treatment tank 1 to cause blockage, the brush bristles 3-1 are attached to the corresponding surfaces of the filter element component 2, and partial particles adsorbed on the surface of the filter element component 2 can be swept through the brush bristles 3-1 when the scraping and brushing component 3 vibrates.

Through above-mentioned exhaust treatment device's design, not only to the form that 7 tops of present agricultural machinery blast pipe buckle simple to operate stable, what install moreover additional scrapes brush subassembly 3 can the rational utilization engine vibration scrape the brush to filter element group spare 2, effectively reduces the jam problem.
