Plastic-removing and rubbing machine for preparation of protected vegetable straw fertilizer

Abstract

The invention provides a plastic-removing and rubbing machine for preparation of protected vegetable straw fertilizer, which can meet the pretreatment requirement for plastic removing and rubbing in early straw fermentation and early package. The machine comprises a roller, a screen and a motor, wherein the motor is arranged on one side of the roller, and is linked with the roller by virtue of a belt pulley transmission mechanism; small dial teeth are arranged on the outer surface of the roller; a plurality of big dial teeth are arranged on the side, far from the motor, of the roller; a charging opening is formed at the upper part of the roller, and the screen is arranged at the lower part of the roller; a discharge hopper is arranged under the roller; a screening and rubbing cavity is reserved between the roller and the screen; and a plurality of rubbing plates are fixed on the roller and in axial parallel to the roller, and is positioned in the screening and rubbing cavity.

Description

technical field [0001] The invention relates to a kneading machine, in particular to a kneading machine for making fertilizer from facility vegetable straws and belongs to the technical field of organic fertilizer production. Background technique [0002] At present, in the process of producing organic fertilizer from facility vegetable straws, the recycled straws contain a large amount of easily entangled plastic ropes, plastic films, household garbage, crushed stones and other sundries. After the main stem of the straw is crushed by a large-scale straw crusher, the particle size is large, and it is not easy to rot and ferment, which affects the fermentation cycle of organic fertilizer; the debris in the crushed material cannot be cleaned and sieved, which affects the fermentation effect of organic fertilizer and the quality of organic fertilizer products in the later stage; debris If it follows the materials into the fermentation workshop, production equipment such as mixe...

AI Technical Summary

Problems solved by technology

After the main stem of the straw is crushed by a large-scale straw crusher, the particle size is large, and it is not easy to rot and ferment, which affects the fermentation cycle of organic fertilizer; the debris in the crushed material cannot be cleaned and sieved, which affects the fermentation effect of organic fertilizer and the quality of organic fertilizer products in the later stage; debris If the material enters the fermentation workshop, it will entangle the production equipment such as the mixer and compost turning machine, which requires a lot of manpower and material resources for cleaning and maintenance, which seriously affects the production cycle of organic fertilizer and increases the production cost of organic fertilizer

The existing drum screening equipment in the market cannot rub the facility vegetable straw material, and the screening efficiency is extremely low; the existing cleaning equipment has a wide variety and is widely used, but it cannot realize the cleaning and rubbing of the facility vegetable straw powder material Function
