Detailed Description
The technical solutions of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.
1, working principle:
the corn is put into the thresher from the top end of the side leakage barrel, falls freely and is sent into the thresher through the guide groove on the rack. The corn cobs are subjected to primary pressure-releasing threshing under the action of the fixed grinding wheel and the rotary grinding wheel, and the circular boss protrusions can control the ungranulated or relatively large corn cobs to perform multiple circular motions inside the thresher so as to achieve the effect of pressure-releasing friction threshing. When the corn cobs are too small or a small amount of corn which is not completely threshed is left after primary threshing, the remaining corn cobs can fall into the screen, the rotation of the threaded roller pushes the corn cobs to move out of the thresher to carry out secondary threshing on the corn, and the threshing and the cob grain separation are carried out simultaneously in the process. In conclusion, the whole threshing process is divided into two-stage threshing, the crushing rate can be effectively reduced under the condition of ensuring complete threshing in the threshing process, if the threshing part is abraded, the threshing function can be realized through proper adjustment, and the continuous use capability is very high.
2, threshing device:
the threshing device is composed of two stages of threshing devices, the first stage is composed of two grinding wheels, the circular truncated cone-shaped bulge controls the arc motion rule of the corn, the kneading and threshing functions are realized in the relative motion of the two grinding wheels, and the larger corn is subjected to the first-step grinding. The second stage consists of five thread-shaped rollers, the rollers drive the corn to move, and the corn is threshed for the second time under the combined action of the mesh screen and the threads. In conclusion, the threshing process uses the threshing principle of hands for reference, and after the rotor is driven by the motor, the threshing effect is achieved through the pressure expelling and kneading action of the corns and the disks.
The design replaces rough impact threshing in a softer way, so that the limit of the machine on the feeding amount and the moisture content of the corn is relaxed, and simultaneously, the high threshing rate and the lower crushing rate can be maintained.
The innovative design of the rotor and the disc ensures that the vibration caused in the working process is reduced, the abrasion of the main part is greatly reduced, the service life is longer and more durable, and in addition, the effects of pressure expelling and kneading are reduced compared with the traditional impact threshing, the noise pollution is reduced, and the working environment is quieter and more comfortable.
3, a separation device:
the separating device mainly separates the corn kernels and the corncobs and discharges the corn kernels and the corncobs out of the thresher. The auxiliary turntable is driven by the rotation of the main shaft, the threaded roller on the auxiliary turntable rotates around the short shaft under the dual acting force of the corncobs and the auxiliary turntable, the corncobs are sent out of the machine body during the rotation of the threaded roller, the movement of the corn kernels is stirred by rotation, the corn kernels which are successfully threshed pass through the small holes under the screening of the sieve, leak into the guide holes, and are finally discharged by the material pouring device.
4, a dust removal device:
the dust removing device adopts a simple fan dust absorption principle, takes air as a carrier, and drives dust to move through one-way air circulation. When the thresher works, the fan is driven to rotate, the removed dust is sucked out, and the dust can be stored in the dust collecting bin or collected into a bag in a unified manner by the dust collecting bin for final treatment.
The dust removal device is mainly composed of a fan cover and fan blades, the fan cover is divided into two parts which are connected through screws, so that the fan can be assembled on the other side of a worker, and the harm of dust to people in the dust removal process is avoided.
5, a transmission device:
the power of the motor or the diesel engine is used as a main power source, and the power is transmitted to the working mechanism through the mutual matching of the rotating shaft and the bearing part, so that the dust removal device is driven to work cooperatively.
The size, the property, the speed and the working environment of the working load of the thresher are comprehensively considered, the type, the structural type and the power rotating speed of the motor are further selected, and the type of the motor is determined. The thresher is driven by a belt and can be flexibly connected with an external locomotive through a main shaft.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are within the scope of the present invention.
