Problems solved by technology

However, seedlings need to borrow a lot of soil year after year. In the past, Hetao, mountainous areas, and under-forest land were the main sources of soil extraction, which has caused a large amount of soil loss and severely damaged vegetation.
It is becoming more and more difficult to obtain soil now, and farmers have to take dry land. Since there are a large number of pesticides in the dry land soil, rice seedlings often suffer from pesticide damage when using this soil to raise seedlings, causing great economic losses to farmers.

Abstract

A precision-shaping straw extruder and an extruding production method of a seedling substrate straw board belong to the technical field of agricultural machinery. Straw is used as raw materials to realize extrusion shaping of a seedling substrate straw board. A cylinder rod of a cylinder is fixedly connected with a push-out rod. A seal baffle is arranged at the abutting joint of a feeding hole of a housing and a discharge hole of a feeding hopper. Two first guide rails are fixed at a bottom end within the housing, and bottom ends of a pressing plate and a plurality of mold plates are connected in a sliding manner with the first guide rails by means of first sliders. Springs are fixed on front side surfaces of the mold plates and a front side surface of a rear sidewall of the housing. A piston rod of a hydraulic cylinder is arranged corresponding to a through hole in a front sidewall of the housing. Left and right sidewalls of the housing both are movable sidewalls. A plurality of push-out teeth of the push-out rod are arranged in a one-to-one corresponding relation with a plurality of mold cavities. Bearings are mounted at two ends of a rotating shaft, and fixedly connected with a base and a support frame by means of bearing blocks. An output shaft of a motor is in transmission connection with the rotating shaft by means of a belt transmission mechanism. Heating devices are fixed on the mold plates. The precision-shaping straw extruder and the extruding production method of the seedling substrate straw board are used for producing the seedling substrate straw board from straw in the extrusion shaping way.

Description

technical field [0001] The invention relates to a crop straw precision molding extruder and a preparation method of using the extruder to prepare seedling raising substrate straw boards, belonging to the technical field of agricultural machinery. Background technique [0002] The annual output of crop straw in my country is about 700 million tons, ranking first in the world. Crop straw is a valuable renewable energy source. However, since there is no economical and efficient way to use it for a long time, more than 60% of the straw is burned by farmers in the field every year, seriously polluting the environment. There are also application bottlenecks such as cost and process in technical methods such as making straw coal and feed, so a large amount of straw is still incinerated every year. [0003] Most of the rice seedling raising in our country adopts the dry seedling raising operation method, which has good seedling raising effect and has been popularized in our country...
