Description

Double shell axial flow pulverizer

Technical field:

The utility model belongs to the technical field of agricultural machinery manufacturing and relates to a straw crushing device.

Background technique:

In the vast rural areas, corn stalks are directly used as fuel for cooking and heating, which has a low benefit rate, causes waste, and also pollutes the environment. Crush the straw and use it in combination with other fuels to burn fully, improve thermal efficiency, and greatly reduce pollution. Straw is also the main feed for livestock, and straw powder can help livestock digest and absorb straw. At present, there is no report on the crushing device for straw.

Invention content:

The technical problem to be solved by the utility model is to disclose a double-shell axial flow pulverizer for pulverizing straw.

The solution of the utility model to solve the technical problem is to use the shell, the front axle, the rear axle, the guillotine, the hammer, the fixed knife, the sieve cylinder and the fan to form a double-shell axial flow pulverizer. The front axle is at the front of the shell, and one end It protrudes from the front side of the shell, and there is a connecting bearing inside the shell. The other end of the front axle is mounted on the connecting bearing, and the rear axle is at the rear of the shell. On the connecting bearing, the guillotine is fixed on the front shaft, and the shaft plate perpendicular to the rear shaft is fixed on the rear shaft. The shaft plate is connected to the hammer through the pin shaft. The fixed knife is fixed on the inner wall of the housing, and the position of the fixed knife corresponds to the hammer. , and the fixed knives and hammers are arranged alternately, the shell is equipped with a screen cylinder, the screen cylinder surrounds the guillotine and the hammer, the rear part of the shell is equipped with a fan, and the shell between the fan and the screen cylinder has a partition net, and the front end of the shell There is a material inlet, the fan corresponds to the material inlet, and the rear end of the shell has a material outlet. When working, start the rotation of the front shaft and the rear shaft, drive the guillotine, hammer and fan, and send the straw into the shell through the feeding port. The powder is sent out through the sieve cylinder and the screen by the fan through the discharge port.

In order to facilitate the overall movement of the pulverizer, a walking mechanism is installed at the bottom of the casing.

This book has the following characteristics:

1. Double-layer casing: one layer of outer protective casing, and two layers of sieve-type inner casing to screen and filter the output materials.

2. After the material is fed, the material is pretreated by the guillotine device.

3. The pulverizer adopts the working principle of axial flow pulverization, and the process is: material inhalation → pulverization step by step → screening → re-crushing → output.

4. The material output system adopts centrifugal output, which increases the material output capacity and avoids the phenomenon of material blocking.

5. In terms of transmission, multi-stage same power transmission is adopted, so that the working speed of each part of the equipment can reach the optimal configuration, and the same power source is used to reduce the energy consumption of the equipment.

6. The power can be powered by electric motor or tractor, which is more convenient for crushing in the field.

7. It can be separated from the walking mechanism, which is convenient for users to crush materials in different places.

8. The crushing efficiency is high. After the prototype is crushed, the particle size of the material can reach φ3～φ5mm, and the working efficiency is 2.5 tons/hour (if the pulverizer sold in the market reaches this particle size, the working efficiency is only 1～1.8 tons/hour. hour).

9. The product can adjust the particle size of the crushed material according to the needs of users.

The utility model can effectively crush the straw powder, and has the advantages of convenient operation, stable operation and low cost.
