Abstract

The utility model discloses a vertical kneading machine for crop stalks, which comprises a machine body, a feed port at the upper end of the machine body and a discharge port at the side of the machine body. There is a cutter with a driving pulley at the lower end of the transmission shaft, and two auxiliary cutting and kneading mechanisms under the primary cutter. Composed of fixed knives, the moving knives and fixed knives are arranged in a staggered manner to form a multi-layer knife group. The inner wall of the body below each fixed knife is equipped with toothed tiles. After preliminary dehydration, the crop stalks enter the feeding port through the conveyor belt and are first cut off by the first cutting knife, and then enter the four knife groups arranged in a specific order to further chop the material. At the same time, there are toothed tiles on the barrel wall of the kneading machine. For each section of crop stalks, it has gone through a high-speed spiral curve movement from the entry to the output, and the waxy and hard shells of the corn stalks have undergone "cutting", "tearing", "rubbing" and "touching" movements to become non-waxy hard husks. The length of 30 ~ 50mm, width 3 ~ 5mm of kneading soft fiber strips, this kind of straw strips are dried and processed by adding nutrients, it becomes a high-quality feed suitable for the digestion requirements of cattle and sheep, which is convenient for storage and transportation.

Description

Crop straw vertical kneading machine

technical field

The utility model relates to a crop straw processing equipment, in particular to a vertical crop straw rubbing machine.

Background technique

my country produces about 600 million tons of various crop straws every year. Due to the low level of crop harvesting mechanization, the existing equipment is not matched, and farmers do not have the ability to process straws. As a result, a large number of straws are burned on the spot in summer and autumn, causing traffic jams. Airplanes cannot land, which seriously wastes energy and pollutes the atmosphere. In order to solve this problem, people have invented a straw grinder, through which the crop straw is crushed and made into feed for livestock. However, the length and hardness of the crushed straw are relatively large, which is very unfavorable for feeding cattle, sheep and ruminant livestock.

Utility model content

The purpose of the utility model is to provide a vertical kneading machine for crop stalks which is novel in structure and can turn crop stalks into the most suitable for animal digestion.

The technical scheme of the utility model is: 1. A vertical rubbing machine for crop straws, including a body, a material feeding port on the upper end of the body and a material outlet on the side of the body, a transmission shaft is installed in the middle of the body, and the upper end of the transmission shaft is loaded The lower end of the mouth is equipped with a primary cutter, and the lower end of the transmission shaft is equipped with a transmission pulley. Under the primary cutter, there are two auxiliary cutting and kneading mechanisms, which consist of a set of moving knives mounted on the transmission shaft and mounted on the inner wall Composed of a set of fixed knives on the top, the movable knives and fixed knives are arranged in a staggered manner to form a multi-layer knife set, and toothed tiles are installed on the inner wall of the body below each fixed knife.

A driving plate is installed on the transmission shaft opposite to the position of the discharge port.

After preliminary dehydration, the crop stalks enter the feeding port through the conveyor belt and are first cut off by the first cutting knife, and then enter the four knife sets arranged in a specific order. The knife set has two types: fixed knife and moving knife. broken. At the same time, there are toothed tiles on the barrel wall of the kneading machine. For each section of crop stalks, it goes through a high-speed spiral curve movement from the entry to the output, and the waxy and hard shell of the corn stalk skin becomes hard without wax after going through the "cutting", "tearing", "grinding" and "touching" kneading movements. The length of the leather is 30-50mm, and the width is 3-5mm, which is kneaded and soft. After drying and adding nutrients, this straw strip becomes a high-quality feed suitable for the digestion of cattle and sheep, which is convenient for storage and transportation. Tests have shown that cattle and sheep do not want to eat ordinary straw after eating the feed, which greatly improves the feed absorption rate of cattle and sheep.

There are also two high-speed rotating drive plates at the lower part of the kneader. The wind driven by the rotation sends the kneaded straw into the first storage bin for drying in the drying cylinder. Realized conveying automation. It can process about 5 tons of straw per hour.

If it is used to process fuel for energy, it only needs to adjust the number and position of moving knives.

The kneading machine is completely designed by the research group and is a special equipment for crop straw processing. The common guillotine cutting and shredding machines at home and abroad are completely different from this, and it does not have the function of kneading.
