Description

Technical Field

[0002] Edible fungi refer to edible mushrooms (large fungi) with large fruiting bodies, commonly known as mushrooms. Due to the wide source of raw materials for edible fungi cultivation and simple cultivation methods, edible fungi have begun to expand on a large scale and industrialized in recent years. Edible fungi bags are the prerequisite for the production of edible fungi. Edible fungi bags are mainly produced by mixing raw materials such as wood chips, rice husks and straw.

[0003] Before making edible mushroom bags, a cutting device is needed to cut the edible mushroom raw materials into fragments. However, when the cutting device cuts the raw materials (such as straw), its crushing mechanism cannot crush all the raw materials during cutting. Some raw materials that are not completely crushed enter the next process. Therefore, a screening device is needed to screen the cut raw materials, screen out the raw materials that are not completely crushed, and re-convey them to the cutting device for crushing. However, some raw materials are mixed with magnetic metals (such as iron nails, iron wires, etc.). In order not to affect the production and processing of edible mushroom bags, the metals mixed in the raw materials need to be screened out, and the existing edible mushroom raw material screening devices cannot effectively remove the metals mixed in the raw materials.

At the same time, a material dividing component is arranged between the two mounting plates 4 to spread the raw materials dropped from the feed hopper 3, so that the two magnetic nets 6 can adsorb the iron nails mixed in the raw materials, thereby further improving the removal effect of the iron nails.

[0021] Specifically, Figure 2As shown, each of the installation mechanisms includes: a slider 8, the slider 8 is fixed to the side wall of the magnetic net 6, and the side wall of the installation groove is provided with a slide groove for the slider 8 to slide.
