Double-use plant material cutting grinder

Abstract

The invention relates to processing machinery for producing edible fungi culture materials, in particular to a double-use plant material cutting grinder. The grinder comprises a frame, a cutting-grinding chamber arranged on the frame, a feeding hopper, a material outlet, a power device and a variable-speed transmission mechanism, wherein a public blanking hopper is directly arranged below the cutting-grinding chamber, namely at the bottom of a filter screen; a centrifugal material-sucking fan device is arranged in the public blanking hopper; the centrifugal material-sucking fan device consists of a pair of air impellers arranged on two sides of the same centrifugal fan main shaft ; and an air outlet of the centrifugal material-sucking fan device is communicated with the material outlet. The grinder can cut and grind straw of various plant materials, weeds, branches, woodwork shavings and other soft/hard raw materials, and helps to directly and smoothly suck out raw material particles even with high water content, thereby achieving the effects of reducing energy consumption, simplifying process and improving production efficiency.

Description

(1) Technical field: [0001] The present invention relates to a kind of processing mechanical equipment which can process various plant materials such as straw, weeds, branches and wood planing materials into edible fungus culture material, especially a kind of dual-purpose plant material cutting and crushing machine. (two) background technology: [0002] With the continuous breakthrough of edible fungi cultivation and production technology, most of the various plant material straws, weeds, fruit tree branches and wood chips can be used as raw materials for bag cultivation of edible fungi by being crushed into granules. my country is a large agricultural country, and the crop straw and fruit tree branches harvested every year are rich in resources. Although these plant straws have been successfully cultivated, in terms of raw material processing, cutting and crushing, due to the different characteristics of these plant materials, if Using the existing pulverizer equipment for...

AI Technical Summary

Problems solved by technology

But the aforementioned plant material cutting and crushing dual-purpose machine also has the following defects. One is that the air inlet of the centrifugal suction fan at the discharge port communicates with the bottom of the cutting and crushing chamber through the "U" shaped discharge channel pipe, so that There is a curved discharge channel that is too long, and the suction resistance increases during the suction process; the second is that the wet processing raw material will be blocked. For example, as long as the moisture content (amount) of the plant raw material exceeds 15%, it will It will greatly increase the workload of the centrifugal suction fan, the suction effect will be greatly affected, and it will even be difficult to discharge the material, thereby reducing the output and production efficiency

The third is that the water content of various plant materials such as orange stalks, weeds, and fruit tree branches is too high, especially in the rainy and humid climate conditions in the southern mountainous areas, the water content of the plant materials collected by mushroom farmers generally exceeds 15%. It takes a lot of time and labor to dry the raw materials repeatedly, such as drying, air drying, and air drying. Even so, it is often difficult to meet the processing requirements, which not only reduces production efficiency, but also affects the freshness of raw materials.
