Problems solved by technology
However, the tight combination of lignocellulose in straw is not conducive to the digestion and absorption of animals.
Therefore, when producing straw feed, the straw must first be cleaned and crushed, and the existing crushing methods and crushing equipment can crush the straw to a certain fineness, but the subsequent crushed materials cannot be cleaned, and the fineness cannot reach the ideal degree

Embodiment Construction
[0032] The specific embodiment of straw superfine pulverization process of the present invention is illustrated below, and the implementation process procedure is as follows:
[0033] The first step is primary crushing of straw: a certain amount of wheat / corn / oil straw to be processed is bundled 2 ( figure 1 Shown) after natural air-drying, unpack, discharge in the V-shaped feeding port 302 ( figure 2(shown) on the operating platform, push the material into the upper cavity 305 of the primary crushing chamber, cover the cover plate 301, and the raw material is clamped on the upper part of the upper cavity 305, and the surface driven by a pair of idler rollers 314, 303 is concave-convex. In the V-shaped conveyor belts 313 and 304, the motor 316 drives the active roller group 314 to rotate, and the straw bales 2 are subjected to downward friction in the conveyor belts 313 and 304, and the surface layer of the straw bales is peeled off, and then enters the bottom 310 and 307. S...

Abstract
The invention discloses a simple and efficient straw ultrafine crushing process and device, and relates to a process method and crushing equipment for crushing crop straw. The invention aims to provide a process method and equipment for carrying out ultrafine crushing on the crop straw, so as to obtain fine straw powder for preparing feed and for other purposes. The process comprises the followingsteps of 1, primarily crushing straw raw materials; 2, carrying out secondary crushing and screening separation on the primarily crushed straw materials; and 3, collecting fine materials and removingdust in a material collecting bin. The device required for implementation of the process is composed of an equipment bracket, a straw primary crushing device, a dust removal device, a rotary screening device, a straw fine crushing device and the material collecting bin, wherein the primary crushing device comprises a pair of carrier roller, a screen and a rack; the dust removal device comprises abuffer air pocket, an induced draft fan, an exhaust pipe, an exhaust and dust removal pipe and a dust washing water tank; the rotary screening device is composed of a screen and a framework; and thefine crushing device is provided with a fine crushing cutter set and is a core component for fine crushing. The ultrafine crushing process and device is mainly used for ultrafine crushing of the cropstraw.
Description
technical field [0001] The invention relates to a processing method and crushing equipment for crop straw crushing, in particular to a simple and efficient superfine crushing process and device for straw. Background technique [0002] With the continuous development of science and technology, people often use crop straw as ingredients when producing livestock and poultry feed, not only because the cost of straw as ingredients is low, but also because the nutritional content of straw is fully utilized, which will not affect the feed intake of livestock and poultry, but also It can promote digestion. However, the tight combination of lignocellulose in straw is not conducive to the digestion and absorption of animals. Therefore, when producing straw feed, the straw must first be cleaned and crushed, and the existing crushing methods and crushing equipment can crush the straw to a certain fineness, but the subsequent crushed materials cannot be cleaned, and the fineness cannot ...
