The invention discloses a dustproof protective cover, relates to the field of dustproof protection, and aims to solve the problems that most of existing dustproof covers adopt an isolation dustproof treatment mode, dust is not fundamentally treated by the method, and the dust is easy to drift into the air and pollute the environment in the process of operating equipment. According to the dustproofprotective cover, two supporting sliding rods are welded to the outer surface of the upper end of a fixed bottom plate; the supporting sliding rods are perpendicular to the outer surface of the upperend of the fixed bottom plate; a hydraulic rod is arranged on one side of each supporting sliding rod, a supporting transverse rod is fixedly installed at the telescopic end of each hydraulic rod, one end of each supporting transverse rod is connected to the outer surface of the corresponding supporting sliding rod in a sleeving mode, and the other ends of the supporting sliding rods are connected to the outer surface of a dust suction hood through adjusting knobs.

The invention discloses an environment-friendly dust removal device. The environment-friendly dust removal device comprises a frame composed of supporting feet and a top plate, universal wheels are arranged at the bottoms of the supporting feet, a control pipe device is arranged in the frame, a first cavity is formed in the control pipe device, first sliding connection grooves are equally formed in the left side inner wall and the right side inner wall of the first cavity, first screw joint rods are arranged in the first sliding connection grooves, a first sliding connection block is in movable fit connection with the interior of the first cavity, a second cavity is formed in the position, below the first cavity, in the control pipe device, a guide connection groove is formed in the inner wall of the right side of the second cavity, a guide connection rod is arranged in the guide connection groove, a guide connection frame with the left side penetrating into the second cavity is in movable fit connection with the guide connection rod, and a first inclined wheel is arranged in the guide connection frame penetrating into the second cavity. The device is simple in structure and convenient to operate, and has multiple purposes, equipment investment is reduced, the metal workpiece clamping and positioning frequency is reduced, time and labor are saved, dust after grinding can be treated in the same device, and the environment-friendly coefficient is high.

The invention discloses a substrate for soilless seedling cultivation of plum vegetables. The substrate contains leaf dregs of plum vegetables, which are decomposed and used as organic fertilizers. Sterilize and provide nutrients to obtain a loose, breathable, water- and fertilizer-retaining substrate, and compared with traditional soil seedlings for plum vegetables, it has the advantages of less pests and diseases, low cost, high survival rate, strong disease resistance, and high yield; Utilizing the plum vegetable leaf dregs and tea dregs can also realize waste utilization, reduce costs, and have strong economic efficiency.
