Dual-roller type banana stalk crushing and returning machine

Abstract

The invention relates to a dual-roller type banana stalk crushing and returning machine. The dual-roller type banana stalk crushing and returning machine comprises a machine frame, a three-point hitch linkage, a transmission device, a stalk shredding device and a stalk crushing device. Left and right ends of front and rear knife shafts are separately connected to left and right side plates through bearings, and the front and rear knife shafts are arranged in a front-and-back parallel manner; and disk coulters are distributed on the front knife shaft, and Y-shaped flail knives are distributed on the rear knife shaft. Further, straight-knife type fixed knives can be arranged just above the front knife shaft. When in work, the disk coulters or further the disk coulters and the straight-knife type fixed knives which are matched with each other are used for firstly chopping banana stalks into minor segments, and then, the Y-shaped flail knives on the rear knife shaft are used for carrying out pick-up crushing on the chopped stalks. The dual-roller type banana stalk crushing and returning machine has the advantages that the problem that knife rollers are wound by banana fibers is effectively solved, and meanwhile, the crushing effect is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a double-roller banana straw crushing and returning machine. Background technique [0002] Banana is a famous tropical economic crop in South China. The main planting areas of bananas in my country are Guangdong, Hainan, Guangxi, and Fujian. Go to the field and burn it with fire after the banana stumps dry up. The disadvantage of this treatment method is obvious. It not only consumes a lot of labor, but also takes a lot of time, so it will inevitably affect the planting of the next crop. It will only aggravate the pollution of the environment. In addition to considering from the perspective of environmental pollution, the banana crop itself is rich in a large amount of organic matter. If the banana straw is treated according to the above method, it will only cause a lot of waste of resources. [0003] At present, there are some knife-roller banana straw smashing a...

Problems solved by technology

The disadvantage of this treatment method is obvious. It not only consumes a lot of labor, but also takes a lot of time, so it will inevitably affect the planting of the next crop. It will only aggravate the pollution of the environment. In addition to considering environmental pollution, the banana crop itself is rich in a large amount of organic matter. If the banana straw is treated according to the above method, it will only cause a lot of waste of resources.

[0003] At present, there are some knife-roller banana straw smashing and returning equipment. When these equipment crush the banana straw, the banana fiber will wrap around the knife roller and the knife, which will cause the returning machine to fail to continue to operate. Therefore, the existing knife-roller banana straw Crushing equipment does not effectively crush banana straw
