The traditional tobacco seedling matrix is ​​made of peat and vermiculite as the main raw materials in a certain proportion, but peat resources are limited. Excessive use of peat can have adverse effects on the environment. It is particularly important to develop raw materials for seedling matrix that can replace peat. In recent years, the production of mushrooms has been large, and a large amount of by-products such as mushroom residues have been produced. These mushroom residues are rich in crude protein, crude fat and nitrogen extracts, and also contain minerals such as calcium, phosphorus, potassium, and silicon. They are quite nutritious. At the same time, mushroom residues have a small specific gravity, are loose and porous, and have the excellent characteristics of ordinary matrices. Mushroom residues can be used to replace part of the peat to make mushroom residue seedling matrix.

[0003] In the process of making mushroom residue seedling medium, the mushroom residue needs to be crushed and screened first. After the mushroom residue is crushed to a certain size, it is mixed with materials such as vermiculite, perlite and fertilizer to finally make the seedling medium. However, since the mushroom residue often has a certain water content, in order to avoid the occurrence of screen clogging during screening, it is often necessary to use vibration screening to screen the mushroom residue.

[0035] The drawings in the present invention are not drawn strictly according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the process of making mushroom residue seedling medium, it is necessary to first crush and screen the mushroom residue, and after the mushroom residue is crushed to a certain size, it is mixed with materials such as vermiculite, perlite and fertilizer to finally make the seedling medium. However, since the mushroom residue often has a certain water content, in order to avoid the occurrence of screen blockage during screening, it is often necessary to screen the mushroom residue by vibration screening. Furthermore, due to the limitation of the overall structure of the device, the crushing and screening part of the mushroom residue seedling medium making equipment in the prior art is often independent of the mixing part, and the whole seedling medium making process is carried out step by step. During the production process of the seedling medium, it is also necessary to transfer and transport the materials between the two parts, which leads to high structural complexity of the whole equipment and limited production speed. At the same time, since some heavier materials such as vermiculite and perlite in the seedling medium are easy to sink to the bottom during the mixing process, the raw material distribution of the seedling medium is not uniform, so it needs to be improved.
