Extrusion device for producing edible mushroom culture medium

Abstract

The invention discloses an extrusion device for producing an edible mushroom culture medium. The extrusion device comprises an upper pressing plate, wherein a lower pressing plate is arranged under the upper pressing plate; the lower pressing plate is connected with a first driving rod; a first rolling wheel is arranged at the top end of the first driving rod; the first rolling wheel abuts against a wedge block; the upper pressing plate is connected with a second driving rod; the second driving rod is connected with a first spring; the second driving rod is provided with a second rolling wheel; the second rolling wheel abuts against a wedge block; the extrusion device further comprises a feeding hopper; the upper pressing plate and the lower pressing plate are in sliding connection with the feeding hopper; the feeding hopper is provided with a feeding hole and a discharging hole; the bottom of the feeding hopper is communicated with a material pushing pipe; the inside of the material pushing pipe is in sliding connection with a material pushing plate; the material pushing plate is connected with a push rod; a swinging rod is arranged on the left side of the push rod; the left side of the swinging rod is connected with a second spring; the swinging rod abuts against a cam; the swinging rod is in sliding connection with a slide block; and the push rod is hinged onto the slide block. The invention aims at providing the extrusion device for producing the edible mushroom culture medium, which can improve the compaction efficiency, so that the problem of an existing extrusion device that the compaction efficiency is low is solved.

Description

technical field [0001] The invention relates to the field of extruding devices, in particular to an extruding device for producing edible fungus culture medium. Background technique [0002] Edible fungi are a class of large edible fungi that belong to the Phylum Fungi, Basidiomycetes or Ascomycetes in taxonomy. Their vegetative structure is branched and filamentous, with cell walls, cells containing obvious nuclei, sexual cell differentiation, capable of sexual reproduction; no chlorophyll, unable to perform photosynthesis, mostly saprophytic or symbiotic ; Their propagule structures are various, such as umbrella-shaped, ear-shaped, head-shaped, flower-shaped, etc., and the colors are also different, including white, red, brown, gray, brown, black, cyan, etc. [0003] Edible mushrooms are rich in nutrients and delicious in taste. They have been listed as a good product in dishes since ancient times. Fang (accounting for 2-8% of the thousand weight), a variety of essential...

Problems solved by technology

[0005] In the process of compaction, an extrusion device will be used, while the existing extrusion device includes a pressing plate, and a platform is provided under the pressing plate, and the inoculated compost is put on the platform, and the pressing plate is used to move downward and compact As the platform is stationary, it can only be passively subjected to the pressure exerted by the medium on it, so that it can generate a reaction force on the medium to cooperate with the pressure plate to compact the compost, because the reaction force of the platform will not accelerate the cultivation The fine particles inside the base move, so the general press plate needs to press the medium several times to compact the medium, and the compaction efficiency is not high
