Description

Rear-mounted rotary dust collector of peanut Technical Field The utility model relates to the technical field of agricultural machinery equipment, in particular to a rear-mounted rotary dust removing device for peanuts. Background In the peanut harvesting operation process, after the working procedures of peanut digging, fruit picking and the like are finished, a large amount of impurities such as broken seedlings, dust and the like are generated by a harvesting machine and are intensively stored in the grass collecting box. The existing peanut harvesting equipment usually adopts a simple filter screen filtering or natural sedimentation mode to treat impurities in the grass collecting box, however, the traditional mode has obvious defects. On one hand, the filter screen is easy to be blocked by larger impurities such as broken seedlings and the like, so that the filtering efficiency is greatly reduced, frequent shutdown and cleaning are needed, and the operation continuity and efficiency are seriously affected, on the other hand, the natural sedimentation mode has poor separation effect on fine dust, and a large amount of dust can be diffused into an operation environment along with air flow in the running and discharging processes of equipment, so that air pollution is caused, the health of the respiratory system of an operator is threatened, and occupational diseases such as pneumoconiosis and the like are easily caused by long-term exposure to the high-dust environment. Meanwhile, scattered dust can be attached to key parts of equipment, so that mechanical abrasion is accelerated, and equipment fault risks and maintenance cost are increased. Therefore, a high-efficiency and reliable dust removing device is needed, which can effectively filter and separate the impurities such as broken seedlings, dust and the like in the grass collecting box, reduce the dust raising problem during peanut harvesting operation, and ensure the safety of the operation environment and the stable operation of equipment. Disclosure of utility model In order to solve the problems, the embodiment of the utility model provides a rear-mounted rotary dust removing device for peanuts, which is used for filtering and separating impurities such as crushed seedlings, dust and the like in a grass collecting box, so that dust emission during operation is reduced.
