Light and simple vertical banana stem crushing and returning machine

Abstract

The invention discloses a light and simple vertical banana stem crushing and returning machine, comprising a light and simple rack, a spacing mechanism, a vertical smashing blade, and a transmission device. The spacing mechanism comprises an upper spacing unit, a lower spacing unit, and a limit switch. The light and simple rack is connected with the upper spacing unit and the lower spacing unit through bolts. A U-shaped arm of the upper spacing unit and an L-shaped arm of the lower spacing unit realize spacing effect on banana stems. Torsion of an engine of the transmission device is transmitted to the vertical smashing blade after deceleration of a reducer, to realize to cut and smash banana stems, and then stems on the upper part are cut and smashed in sequence by cutters of the vertical smashing blade in a process of falling down with gravity. The upper spacing unit and the lower spacing unit are used to limit banana stems from two points on a radial direction. The vertical smashing blade realizes to cut and smash banana stems. The machine can efficiently complete crushing and field-returning of the banana stems in low energy consumption in one time, so as to improve effective utilization rate of banana stem resources. The machine is light and simple in structure, and flexible in moving.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a light and simple vertical banana stalk crushing and returning machine. Background technique [0002] Banana is one of the world's famous tropical economic crops. The main planting areas of bananas in my country are Guangdong, Guangxi, Hainan, and Fujian. Banana stems are the main by-products of banana production areas. The annual production of banana stems in the country is as high as 3,000. tons. At present, except for a small part of banana stems used as fertilizer, most banana planting areas still use the traditional method to deal with banana stems: first remove the leaves and tail tips, and then cut them manually and transport them to the field for natural treatment after about 2 months. Decompose or incinerate after drying up. The disadvantage of this treatment method is obvious, not only consumes a lot of labor, but also takes a lot of time, so it will in...

AI Technical Summary

Problems solved by technology

The disadvantage of this treatment method is obvious, not only consumes a lot of labor, but also takes a lot of time, so it will inevitably reduce the production efficiency of crops. From another perspective, the large amount of smoke produced by burning stalks will only aggravate the deterioration of the ecological environment. At the same time, a large amount of organic matter rich in banana stems cannot be fully utilized, which will only cause a lot of waste of straw resources

[0003] At present, the main factor limiting the low utilization rate of banana stalks is the lack of efficient field banana stalk processing equipment.

Due to the long time from banana harvesting to stalk processing, the water content of banana stalks decreases and the fiber increases. The existing banana stalk crushing and returning machines need to push down the stalks and other operations to achieve relatively good crushing. Moreover, during the operation process, the machine tool is easy to wind a large amount of fibers, which increases the energy consumption of the machine tool and reduces the efficiency.

[0004] Therefore, in the tropical banana planting areas in southern my country, there is an urgent need for a banana stalk crushing and returning machine with simple and reliable structure, flexible and convenient movement, low energy consumption and high efficiency, in order to solve the problem of low utilization rate of banana stalk resources and environmental deterioration. question
