Soil screening device of round baler

Abstract

The invention discloses a soil screening device of a round baler. The device comprises a mud removing device and a soil screening device, the mud removing device comprises a pressure applying crawlerbelt pulled by a first transmission roller, a mud removing plate installed below the pressure applying crawler belt and a mud scraping cutter arranged on and closely fitting the lower surface of the mud removing plate; the soil screening device comprises a rotary shaft, an arc baffle plate arranged above the rotary shaft, an arc screening plate below the rotary shaft, fixed frames installed at thetwo ends of the rotary shaft, a fixed rod installed between the fixed frames and second stirring teeth fixedly arranged on the fixed rod. The pressure applying crawler belt of the mud removing devicestrictly controls the distance between the mud removing plate and the pressure applying crawler belt, so that straw entering the mud removing device is extruded by the pressure applying crawler belt,and wet mud is extruded out by a mud filtering through hole; the straw treated by the mud removing device enters the soil screening device and passes above the arc screening plate under the driving of the second stirring teeth, and under the effect of the pressure applying crawler belt arranged forward, soil blocks are smashed and can be more easily screened out through the arc screening plate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a soil screening device for a round straw baler. Background technique [0002] Every time the busy farming season is over, straw will be left everywhere in the fields. Burning straw will pollute the environment and affect the atmospheric climate. Straw can be used to prepare feed, living fuel, and retting fertilizer, and has a wide range of uses. However, if a large amount of stalks in the field are to be recycled, they will face the problem of stalk collection. [0003] The baler in the prior art can solve the problem of straw collection. However, after the straw has been piled up in the field for a period of time, the straw will stick to the ground. Coupled with the influence of rain and dew, many straws will have soil on them. When the straw with soil is involved, the baler will run poorly or even be blocked due to the siltation of the soil; in addition, colle...

However, if a large amount of straw in the field is to be recycled, it is faced with the problem of straw collection.

[0003] The baler in the prior art can solve the problem of straw collection. However, after the straw has been piled up in the field for a period of time, the straw will stick to the ground. Coupled with the influence of rain and dew, many straws will have soil on them. When the straw with soil is involved, the operation of the baler will be poor or even blocked due to the siltation of the soil; in addition, collecting the straw with soil is also very unfavorable for the secondary use in the later stage, increasing the cleaning cost of the straw
