Residual film recovery device and operation method thereof

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a residual film recovery device and an operation method thereof. The device comprises a carrier, a stalk pulling mechanism and a residual film recovery mechanism; the stalk pulling mechanism comprises a stalk pulling wheel, a main stalk pulling wheel, an auxiliary stalk pulling wheel, a cotton stalktransfer wheel set, a first stalk cutting rotor, a second stalk cutting rotor and a cotton stalk collecting and throwing device; the residual film recovery mechanism comprises a film loosening wheel,a soil retaining plate, a film picking wheel, a film brushing transfer wheel and a film collecting box; the stalk pulling mechanism is connected with the front of the carrier, and the residual film recovery mechanism is connected with the rear of the carrier, so that on a cotton field after picking, pulling, chopping and residual film recycling operation of the cotton stalk and the surface and underground residual film can be completed in one time by the carrier, which not only greatly improves the agricultural production efficiency of cotton field post-treatment, but also greatly improves the quality and quantity of the pulling and cutting of the cotton stalk and the residual film recovery.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a residual film recovery device and an operation method thereof. Background technique [0002] China is the world's largest cotton producer. At its peak, there were nearly 20 provinces and regions planted in the country, covering an area of ​​90 million mu. It is an important economic crop for China's agricultural production. The climate and geographical conditions in Xinjiang are very suitable for the growth of cotton. Due to drought and water shortage, the cotton planting area has been at a low level for a long time in the past. In the past ten years, driven by drip irrigation technology under plastic film, the cotton industry has developed rapidly. By 2018, cotton production accounted for 83.9% of the country's total, and the planting area exceeded 40 million mu. , but due to the lack of high-efficiency residual film recovery machinery, a large amoun...

[0002] China is the world's largest cotton producer. At its peak, there were nearly 20 provinces and regions planted in the country, covering an area of ​​90 million mu. It is an important economic crop for China's agricultural production. The climate and geographical conditions in Xinjiang are very suitable for the growth of cotton. Due to drought and water shortage, the cotton planting area has been at a low level for a long time in the past. In the past ten years, driven by drip irrigation technology under plastic film, the cotton industry has developed rapidly. By 2018, cotton production accounted for 83.9% of the country's total, and the planting area exceeded 40 million mu. , but due to the lack of high-efficiency residual film recovery machinery, a large amount of residual plastic film left in the soil has caused very serious white pollution, which directly led to a sharp decline in the germination rate of cotton seeds, and the decline in some areas has reached 25%, making The output of cotton planting has dropped seriously, which directly affects the income of cotton farmers. If no effective measures are taken, it will inevitably lead to the serious problem that the land cannot grow crops. At present, experts at all levels of government, agriculture, scientific research departments and agricultural machinery enterprises in our The solution is basically to smash the cotton stalks and then recycle the residual film. The problem with this technical solution is that there are still a lot of broken stalks and stubble on the ground after the upper cotton stalks are broken, which can directly affect the next step. The effect of recycling soil residual film makes it difficult for the recovery rate of surface residual film to exceed 80% in that year
