the right side of the shell 1 is provided with a transmission part 11, the transmission part 11 enables the rotating directions of the rotating shaft 3 and the brush roller 9 to be opposite, meanwhile, the rotating shaft 3 rotates intermittently, and the brush roller 9 rotates continuously.
In order to realize fixation, a connecting seat 12 is arranged on the front side surface of the shell 1, and the connecting seat 12 is fixed at the rear of the harvester through bolts.
In order to make the filter cartridge 4 function to divide large-particle straws and fine dust, the outer edge surface of the filter cartridge 4 is full of through holes 13.
In order to realize transmission, the transmission part 11 comprises a main shaft 14, the main shaft 14 is driven by the harvester to rotate through a belt and a belt pulley, a sheave mechanism 15 is arranged between the main shaft 14 and the rotating shaft 3, and the sheave mechanism 15 enables the rotating shaft 3 to rotate intermittently; the brush roller 9 and the main shaft 14 are linked through a belt and a belt pulley.
In order to realize better matching, the number of the telescopic plates 10 is six, and the geneva gear 15 rotates 60 degrees each time; when the rotating shaft 3 stops rotating each time, two expansion plates 10 are symmetrically distributed on the front side and the rear side of the feeding hole 2.
In order to realize the stable rotation of the rotating shaft 3, the filter cartridge 4 and the expansion plate 10, the expansion plate 10 is divided into three sections, and a pressure spring 16 is connected between the sections; wherein a section fixed to the rotation shaft 3 penetrates the filter cartridge 4 and is fixed to the filter cartridge 4.

In order to facilitate the rotation and the extension of the expansion plate, the length of the left and right directions of the discharge port is smaller than that of the expansion plate, so that the left and right ends of the expansion plate are always arranged in the shell 1.
When the harvester is used, the whole shell 1 is arranged behind the harvester through the base and the bolts, the discharge opening 8 of the shell 1 faces downwards, and the feed opening 2 faces upwards; then, slag outlets on the left side and the right side of the harvester are connected to the feed inlet 2 through pipelines; and the main shaft 14 at the right side of the shell 1 is driven to rotate by a belt and a belt wheel, and meanwhile, the exhaust fan 6 at the left side of the shell 1 needs to be connected. The installation process is convenient and fast, and the harvester can be suitable for harvesters of different sizes.
After the installation is finished, whether the dust collection box 7 is accumulated or not is checked, and after the dust collection box is cleaned, normal harvesting operation can be started.
During harvesting, straws crushed by the harvester are discharged from slag outlets on the left side and the right side of the harvester at a high speed and enter the feed inlets 2 on the left side and the right side of the shell 1 through pipelines, and the feed inlets 2 are arranged on the left side and the right side, so that the high-speed straws enter the shell 1 from the left side and the right side and flow towards the middle, the speed is reduced, the whole rotating shaft 3, the filter cartridge 4 and the expansion plates 10 are driven to rotate intermittently by actively driving the sheave mechanism 15, and when the expansion plates 10 stop rotating, the two expansion plates 10 are positioned on the front side and the rear side of the feed inlets 2 (see the attached drawing 3), and the straws entering the shell 1 are accumulated in a gap between the two uppermost expansion plates 10 and the shell 1 and are gradually accumulated; when the straw is fully stacked, the rotating shaft 3 can rotate forwards clockwise by 60 degrees, so that the straws originally positioned at the top are driven to rotate along the shell 1 and the expansion plate 10; the empty part originally at the rear side can be positioned at the top and continues to receive the material.
Because the rotating shaft 3 is arranged eccentrically and is located at a lower position, the space between two adjacent expansion plates 10 and the shell 1 is smaller downwards; consequently after pivot 3 drives the straw and rotates downwards, because the space diminishes, the straw can be extrudeed, and along with the continuous rotation of pivot 3, the compression ratio of straw also can be higher and higher, make original fluffy straw, by the compaction, discharge inside dirty gas, the combustion gas can enter into the inside of straining a section of thick bamboo 4 through straining a section of thick bamboo 4, simultaneously because cover 5 and air exhauster 6 are installed to the left end of straining a section of thick bamboo 4, consequently under the effect of air exhauster 6, the gas of dirty and tiny straw can be taken out by air exhauster 6, and enter into in the dust collection box 7, filter screen 17 through the dust collection box below carries out abundant filtration back, will compare purer gas outgoing.
When the straws are driven to rotate to the lowest part of the shell 1, the straws are not extruded at the moment and can be discharged from the discharge port 8 because the discharge port 8 is arranged at the lowest part; the discharged material is compressed due to the volume, so that the density is increased, the discharged material cannot float at will, and the discharging and the dissipation are avoided. Meanwhile, the brush roller 9 is arranged at the discharge port 8, so that straws clamped on the filter cartridge 4 can be cleaned under the action of the brush roller 9, and the situation that the through hole 13 on the filter cartridge 4 is blocked to influence continuous use is prevented; and because the brush roller 9 continuously rotates all the time, the brush roller 9 can completely clean the filter cartridge 4 along with the intermittent rotation of the filter cartridge 4.
The operation of collecting, compressing, discharging dust, discharging and collecting the straws is realized by reciprocating in sequence; and because the intermittent rotation of the rotating shaft 3 can make the whole device continuously carry out the process, the removal of the straws cannot be influenced. After the dust collection box is used for a period of time, the dust collection box 7 needs to be cleaned, and the dust collection box 7 is placed to contain too much sundries, so that the filtering effect is reduced.
The space at the feed inlet 2 and the space at the discharge outlet 8 in the whole device are separated by the expansion plate 10, so that materials and dust cannot be directly discharged from the discharge outlet 8; because the cost and the frictional resistance are considered, the device is not provided with sealing structures such as rubber rings, and the like, a small part of dust still escapes, but most of dust collection is not influenced, and the ideal effect can be achieved.
This device compact structure, the cooperation relation is inseparable between each spare part, and clearance through pivot 3 rotates, and the cooperation is strained section of thick bamboo 4 and is carried out the separation of dust and straw to through compressing the straw discharge, the effect that the harvester afterbody presses down dirt has been realized to the mode that the dust was collected, places straw and dust loss.
The device skillfully eccentrically arranges the rotating shaft 3, so that the distance between the filter cartridge 4 and the shell 1 is reduced from top to bottom in sequence after the filter cartridge is eccentrically arranged; therefore, when the material is stirred to the lower side from the lower part, the extrusion can be realized, and the continuous work can be realized.
Because traditional harvester generally has two row cinder mouths, consequently there are two feed inlets 2 in this device, arrange about through two feed inlets 2, can make high-speed exhaust straw, control and offset each other to reduce the speed of straw, and along with the rotation of pivot 3, the straw is compressed the back, more can become static state, and the density grow, is not easily drifting about, prevents that the straw from flying and polluting the environment.
In this device, strain a section of thick bamboo 4 and can play the effect of cutting apart straw and dust and be individual, make the straw discharge after can compressing, and the inside that dust and tiny straw that wherein contain can enter into dust collection box 7, this part is dust pollution's leading cause also, collects through dust collection box 7, can effectually prevent its diffusion.
