Description

A kind of straw shredder

technical field

The utility model relates to a straw pulverizer.

Background technique

The straw shredder is mainly composed of motor, rotating shaft, cutter mechanism, crushing chamber and other components, which can be applied to the shredding and processing of biomass such as cotton stalks, bark, branches, corn stalks, wheat straw, rice straw, etc., and the processed finished products It can be used for power generation, papermaking, wood-based panels, ethanol extraction, etc. It is currently the core processing equipment for straw recycling.

However, most of the existing straw pulverizers have the following defects:

(1) Feed by manual method, the work efficiency is low, and the feed is uneven, so it is easy to make some straws not be crushed well, resulting in waste.

(2) The motor transmission part cannot flexibly adjust the rotational speed of the rotating shaft, which greatly restricts the use of the straw crushing vermicelli machine, and the transmission efficiency is low and the power consumption of the motor is high.

Therefore, it is necessary to improve the existing straw grinder.

Utility model content

The purpose of the utility model is to provide a straw grinder, which mainly solves the problems of low working efficiency, limited use and high power consumption of the existing straw grinder.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A straw grinder, comprising a crushing chamber with a feeding channel and a discharging channel, a rotating shaft extending into the crushing chamber at one end, knife holders located inside the crushing chamber and arranged on both sides of the rotating shaft, arranged side by side The cutting blade on the knife rest, and the motor, the feed channel is connected with a conveyor, the collection box is arranged under the discharge channel, and the motor is connected with the other end of the rotating shaft through a transmission mechanism, and the motor A frequency converter is also connected; the transmission mechanism includes a driving wheel fixed on the motor shaft, and a driven wheel connected with the driving wheel through a transmission belt and fixed on the other end of the rotating shaft.

Preferably, the conveyor is a belt conveyor.

Preferably, the diameter ratio of the driving wheel to the driven wheel is 1:1.

Compared with the prior art, the utility model has the following beneficial effects:

(1) The utility model is equipped with a conveyor at the feeding channel, and preferably adopts a belt conveyor, so that not only the conveying capacity is strong, the maintenance is convenient, but also the automatic and uniform feeding of materials can be well realized, thereby effectively improving the cost While improving the working efficiency of the utility model, it can largely ensure that the crushing degree of the straw can meet the requirements and avoid waste.

(2) The utility model is equipped with a transmission mechanism composed of a driving wheel, a transmission belt and a driven wheel. Compared with the transmission mode adopted by the motor part of the straw pulverizer in the past, it has the characteristics of high transmission efficiency and can achieve a ratio close to 1:1. Transmission efficiency, thus reducing the power consumption of the motor. The frequency converter provided can adjust the rotational speed of the motor, thereby further facilitating the cutting and crushing of various crop stalks in the utility model, and greatly improving the applicability of the utility model.

(3) The utility model is equipped with a collection box at the discharge channel, which facilitates the collection and storage of crushed materials, and prevents the materials from being scattered and affecting the surrounding environment.

Among them, the names of parts corresponding to the reference signs are: 1-conveyor, 2-feed channel, 3-crushing chamber, 4-rotating shaft, 5-knife holder, 6-cutting blade, 7-driven wheel, 8- Transmission belt, 9-drive wheel, 10-motor, 11-frequency converter, 12-discharging channel, 13-collecting box.

Detailed ways

As shown in Figure 1, the utility model comprises a conveyor 1, a crushing chamber 3, a rotating shaft 4, a knife rest 5, a cutting blade 6, a transmission mechanism, a motor 10, a frequency converter 11 and a collection box 13. The crushing chamber 3 is respectively provided with a feed channel 2 and a discharge channel 12 , wherein the feed channel 2 is connected to the conveyor 1 , and the collection box 13 is arranged below the discharge channel 12 . One end of the rotating shaft 4 extends into the crushing chamber 3, and the other end is connected to the motor 10 through a transmission mechanism. The knife rest 5 is located in the crushing chamber 3 and is arranged on both sides of the rotating shaft 4, and the cutting blade 6 are arranged side by side on the knife rest 5.

The transmission mechanism is used to transfer the kinetic energy generated by the rotating shaft of the motor 10 to the rotating shaft 4, which includes a driving wheel 9 fixed on the rotating shaft of the motor 10, and is connected with the driving wheel 9 through a transmission belt 8 and fixed on the rotating shaft. The driven wheel 7 on the shaft 4, and, in order to further improve the transmission efficiency, preferably, the diameter ratio of the driving wheel 9 to the driven wheel 7 is 1:1. The frequency converter 11 is connected with the motor 10 for adjusting the speed of the motor 10 .

When the utility model is in use, the motor 10 is first turned on, and then according to the type of straw material and the degree of crushing, the frequency converter 11 is used to adjust the speed of the motor 10, and the motor 10 drives the rotating shaft through the driving wheel 9 and the driven wheel 7 in turn. 4 rotates, and then drives cutting blade 6 to rotate. Then, use the conveyor 1 to evenly send the straw material from the feeding channel 2 into the crushing chamber 3. In this embodiment, a belt conveyor is used to transport the straw material, which has the characteristics of strong conveying capacity, simple structure and easy maintenance. And can realize automatic operation conveniently.

When the material enters the crushing chamber 3, it will be continuously shortened and crushed by the high-speed rotating cutting blade 6, and relying on the action of the cutting blade 6 and the inner wall of the crushing chamber 3, the straw material will be kneaded into filaments to achieve uniform crushing. Come out from the discharge channel 12 at last, and enter in the collecting box 13 and collect.
