Description

Technical Field

[0001] The utility model relates to a combined operation machine for crushing straws and returning them to fields and recovering ground film. Background Art

[0002] The application of mulch film planting technology in the arid areas of the north has become very common. At present, economic crops such as cotton are all planted using mulch film, and agricultural crops such as corn, beets, peppers and tomatoes are also widely used.

[0003] Although many recycling measures have been taken, the current situation of mulch film recycling is still very serious due to the increase in the total amount of mulch film cultivation.

[0004] Existing integrated powdered straw and plastic film recycling machines usually adopt an integrated integrated machine technology architecture mode. The traction locomotive tows the straw crushing and plastic film recycling machine. The overall length of the machine is more than ten meters. There are two problems when operating in the field: the first is that the height of the traction locomotive chassis from the ground is 35 cm to 55 cm, and the straw crushing mechanism and plastic film recycling machine towed by the rear are traveling on the crops to be crushed. For example, the height of cotton straw is generally about 80 cm to 130 cm, and the lignified hardness of cotton stalks is relatively high, which not only increases the resistance and fuel consumption of the traction locomotive's driving operation, but also the components of the entire bottom of the axle of the traction locomotive will be scratched and worn by the cotton stalks, which will not only cause the bottom structure of the axle to wear, but also easily cause the bottom oil pipeline line, electrical line and sensor to malfunction, and also cause the crop straw to be crushed and broken, affecting the operation effect.

[0005] Therefore, a combined machine for straw crushing and returning to the field and plastic film recovery, which can reduce the workload and improve work results, came into being. Summary of the invention
