Description
Technical Field
The utility model belongs to the technical field of agricultural machine, specifically speaking relates to a spiral sword reducing mechanism of banana straw still field machine.
Background
Bananas occupy an extremely important position in the fruit trade in the world, are the most important fruits in tropical and subtropical regions, are deeply favored by people by virtue of rich nutrition, faint scent and delicious taste, and are sold in the largest amount of fresh fruits in the world. China is one of the main banana production areas in the world, and in subtropical regions of China, the banana industry has become the underpinning industry of agricultural economy and plays an important role in agricultural economy and social development. The main byproducts of bananas comprise banana pseudostems and banana leaves, and are bulk agricultural wastes in tropical regions of China. Because of low mechanization level and lack of matched agricultural machines, the banana straws are still processed mainly in the traditional mode of manual cutting, carrying to the field and self-rotting in China. The traditional mode has many disadvantages, which are mainly embodied in the following 3 aspects that firstly, manual operation is mainly adopted, which causes large labor intensity, low working efficiency and high operation cost; secondly, the time for stacking and decaying the stalks is long, so that the spreading of plant diseases and insect pests is easy to cause, and the environment is polluted; thirdly, banana straws are difficult to process in time by manpower, and the banana garden is influenced to be updated.
At present, banana stalks are directly smashed and then thrown into a field by utilizing a banana stalk smashing technology, so that the next round of planting is facilitated, organic matters in soil can be increased, and the soil structure of a banana garden is improved. The smashing device is a core component of the banana straw smashing and returning machine, and part of the smashing device needs to be reasonably and effectively designed.
SUMMERY OF THE UTILITY MODEL
The utility model belongs to the technical field of agricultural machine, specifically speaking relates to a spiral sword reducing mechanism of banana straw still field machine. Which comprises a hollow roller, a left spiral blade and a right spiral blade. The spiral knife is mainly characterized in that: the cutter is designed by adopting a spiral profile curve, so that the crushing performance of the banana straw returning machine is improved. The utility model relates to a simple structure innovation accords with reality, and the banana straw returning machine that adopts spiral sword reducing mechanism has the characteristics that crushing effect is strong, the cutter durability is strong. Therefore, the banana straws can be efficiently crushed and returned to the field with high efficiency and low energy consumption, the utilization rate of banana straw resources in the main production area of China can be effectively improved, and the social ecological environment is improved.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a spiral sword reducing mechanism of banana straw returning field machine which characterized in that: comprises a roller (1), a left spiral blade (2) and a right spiral blade (3); the left spiral blade (2) is arranged on the left side of the roller, and the right spiral blade (3) is arranged on the right side of the roller and symmetrically distributed on the roller; and the left spiral blade (2) and the roller (1) are fixedly connected, and the right spiral blade (3) and the roller (1) are fixedly connected by welding.
Further: the outer diameters of the left spiral blade (2) and the right spiral blade (3) are both 500-550 mm.
Further: the cutting angles of the cutting edge (2.1) of the left helical blade and the cutting edge (3.1) of the right helical blade are both 30-35 degrees.
Further: the thickness of the left spiral blade (2) and the thickness of the right spiral blade (3) are both 5 mm.
Further: the thread pitches of the left spiral blade (2) and the right spiral blade (3) are both 90 mm.
Further: the outer diameter of the roller (1) is 200 mm.

Detailed Description
The present invention is described below with reference to the accompanying drawings and examples, and the technical solutions in the examples of the present invention are fully and clearly described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.
As shown in figure 1, figure 2 and figure 3, the utility model discloses a spiral knife smashing device of banana straw returning machine, which comprises a roller (1), a left spiral blade (2) and a right spiral blade (3). The left spiral blade (2) is arranged on the left side of the roller, the right spiral blade (3) is arranged on the right side of the roller, and the left spiral blade and the right spiral blade are symmetrically distributed on the roller, so that the crushing effect of the banana straw returning machine can be effectively enhanced. The left spiral blade (2) is fixedly connected with the roller (1) through welding, and the left spiral blade (2) is fixedly connected with the roller (1) through welding. The outer diameters of the left spiral blade (2) and the right spiral blade (3) are 500-550 mm. The cutting angle between the cutting edge (2.1) of the left spiral blade and the cutting edge (3.1) of the right spiral blade is 30-35 degrees, so that the crushing rate of the straw can be effectively improved. The thickness of the right spiral blade (3) and the left spiral blade (2) is 5 mm. The screw pitch of left side spiral blade (2) and right spiral blade (3) is 90mm, left side spiral blade all adopts high carbon steel integrated into one piece with right spiral blade, can improve the durability of cutter greatly.
