Straw crusher with high efficiency

Abstract

The invention discloses a straw crusher with high efficiency. The straw crusher comprises a shell, an upper opening of the shell is movably connected with a conveying device, a returning device and adust removing device are fixedly connected to the two side faces of the shell respectively, a reamer device is fixedly connected inside the shell, a double-reamer device is arranged under the reamer device, a pulverizing wheel device is fixedly connected under the double-reamer device, a filtering sieve is arranged under the pulverizing wheel device, and the lower side of the filtering sieve is fixedly connected with a lower side opening of the returning device through the shell. The straw crusher rapidly conveys straw to a feeding port through a feeding system; through the reamer device, thedouble-reamer device and the pulverizing wheel device, the straw which is different in shape is reamed and pulverized into powder, and therefore powder is formed rapidly; through the filtering sieve,the rough powder is sieved out; through the returning device, the powder is reamed and pulverized again, and therefore working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a high-efficiency straw crusher. Background technique [0002] Crusher generally handles larger pieces of material, and the product size is coarser, usually greater than 8mm. Its structural feature is that there is a certain gap between the broken parts and they do not touch each other. Crusher can be divided into coarse crusher, medium crusher and fine crusher. Generally speaking, the materials processed by the grinding machine are relatively fine, and the product particle size is fine, up to 0.074 mm, or even finer. With the mechanization of modern agricultural planting, while a large number of crops are planted, the problem of straw has also followed. The people of the country attach great importance to the problem of smog caused by burning straw, and the burning of straw is explicitly prohibited. With the development of renewable energy, Straw has also been proposed as a...

Problems solved by technology

With the mechanization of modern agricultural planting, while a large number of crops are planted, the problem of straw has also followed. The people of the country attach great importance to the problem of smog caused by burning straw, and the burning of straw is explicitly prohibited. With the development of renewable energy, Straw has also been proposed as a new energy raw material. More than half of the photosynthetic products of crops exist in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource. , but the straw is bulky, takes up space, and is inconvenient to store in large quantities. It can only be broken first and then stored. However, the ordinary crushers currently used for straw have poor crushing effect and low efficiency, so a high-efficiency straw crusher is urgently needed.
