The utility model discloses a quartz sand dehydration screen belongs to quartz sand processing technical field, and it is to solve the component of the uniform speed feeding of not usually being equipped with in prior art, thereby when quartz sand feeding to dehydration screen, it can appear the situation of a large number of gushing into screen surface in a short time, so as to partial accumulation is too thick, wherein the material layer of being too thick can hinder moisture to discharge, thereby reducing dehydration efficiency, increasing product moisture content, influencing quartz sand quality, and under the condition of uneven screen surface load, it can also aggravate screen mesh abrasion, shorten the service life of equipment problem. Including base, the dehydration screen frame is installed to the top of base, and the vibration screen mechanism is installed to the four end contact points of dehydration screen frame top and it, the polyurethane screen mesh is fixedly installed to the middle part of dehydration screen frame, and the uniform material anti -stacking mechanism is jointly installed to one side of dehydration screen frame middle part and one side of base, the uniform material anti -stacking mechanism includes uniform material subassembly, and uniform material subassembly fixed mounting is in one side of base.

This invention relates to the field of farmland treatment technology, specifically to a fixed-point root crushing drill bit assembly based on straw return to the field. It includes a concave main frame and an inverted concave auxiliary frame for connecting to an external machine. The main frame and auxiliary frame are fixedly connected vertically. A drill rod is also provided on the top of the auxiliary frame, and the top of the drill rod is connected to an external power structure. A first sliding frame and a second sliding frame are respectively embedded and fixed on the bottom surface of the main frame along the front-rear direction. A positioning hook module and a dynamic crushing module are respectively installed at the first and second sliding frames, and a dynamic repositioning module is provided between them. This invention achieves integrated processing of straw root positioning, loosening, extraction, cleaning, and dynamic crushing through multi-module collaborative operation. It effectively solves problems such as incomplete root processing, easy entanglement of blades, and low operating efficiency during straw return to the field, thereby achieving efficient and precise processing of straw roots.

The present application relates to the technical field of coal mining, and particularly relates to a retracted drill bit device for coal seam drilling test. The present application provides a retracted drill bit device for coal seam drilling test, which comprises a retraction device and a split device. The retraction device comprises a retraction main body in a columnar shape, a drill rod joint and a split interface arranged at two ends of the retraction main body respectively, the drill rod joint is fixedly connected with a drill rod, the split interface is connected with a bearing of the split device, a crushing device is arranged on the outer side surface of the retraction main body, the crushing device is driven to rotate by rotating the retraction main body, so as to crush the rock which hinders the retraction of the retraction device; one end of the split device away from the retraction device is fixed with one end of a test device in a linear shape, the retraction device and the split device are moved from one end of the drilling hole to the other end, so as to lay the test device in the drilling hole. The present application provides a retracted drill bit device for coal seam drilling test, which can lay the test device in the drilling hole.

This utility model relates to a buried wire device for water conservancy and hydropower projects, belonging to the field of water conservancy engineering technology. The buried wire device includes: a connecting frame disposed at the rear end of the buried wire device; and a buried wire assembly disposed below the connecting frame. The buried wire assembly includes an adjusting frame disposed below the connecting frame, and a shovel plate is disposed inside the adjusting frame via a rotating shaft. By setting the adjusting frame of the buried wire assembly, the tilt angle of the shovel plate can be adjusted, allowing the soil to accumulate towards the center of the trench when backfilling near the trench, thus improving the uniformity of soil backfilling. By setting guide strips and dispersing strips, the soil scooped up by the shovel plate can be evenly dispersed, ensuring that the soil is evenly spread in the lower inner part of the trench during backfilling, reducing the time and manpower spent on manually adjusting the soil backfill quality.
