Positioning buckle system on the net frame for restoration of topsoil in degraded grassland of mountainous desert grassland

Abstract

The invention discloses a positioning and buckle system on a net frame for restoring the topsoil of a mountain desert steppe degraded grassland. The net frame includes a fixing pile and a filter screen assembly that can be separated from each other. The bracket is used to quickly and easily fix the fixed pile on the ground, and does not hinder the storage and transportation of the fixed pile; the filter screen assembly includes a screen main body and two connecting columns respectively arranged at both ends of the screen main body, the two The main body of the filter screen can be wound around each connecting column, so that the distance between the two connecting columns can be adjusted. On the fixing pile, there are mounting holes for accommodating the connecting columns along the vertical direction. The buckle system includes a hole plug, and the hole plug is used to be fastened at the opening of the installation hole in which the connection post is built, so that the connection post and the installation hole are fixedly connected.

Description

technical field [0001] The invention relates to the technical field of topsoil reconstruction and vegetation restoration of degraded grasslands, in particular to a positioning buckle system on a net frame for restoring topsoil of degraded grasslands in mountainous desert grasslands.

[0002] Grassland degradation and windbreak and sand fixation have always been a worldwide problem. For my country, the severity of windbreak and sand fixation is even more serious. Although my country has a vast land area, the desertification area is actually too large. People are doing their best to carry out related work. To control desertification from various angles, many scientific research institutions have carried out work with their own emphasis on the restoration of grassland topsoil in mountainous desert steppe degraded land. For the essential hardware equipment in this work, that is, the frame structure At present, the current main net frame structures are basically recorded in the patent literature, such as the net frame structure and method for the restoration of desert grassland degraded grassland surface soil with application number CN201310121943.5, and the net frame structure and method for desertified grassland with application number 201520982911.9 The protective net frame for the restoration of degraded pasture topsoil, the applicant found many problems in the process of specific treatment of degraded pastures, that is, the existing positioning buckle system on the mesh frame for restoration of degraded pasture topsoil in mountainous desert grassland has many deficiencies As a result, the actual processing work is subject to many limitations, and the work process is relatively complicated; specifically:

[0003] In the existing net frame structure, the base, the fixed rod and the protective net are fixed as a whole, which can improve the overall strength and adapt to the continuous strong wind. It is difficult to arrange the equipment on a large flat site, and there are some exposed stones or sunken holes on the ground, which will also bring inconvenience to the installation of this overall equipment;

[0004] Although the existing screen frame structure is designed with the stability of installation in mind, it is found that its stability is still insufficient in actual work. In the process of long-term use, it is attacked by wind and sand all day long. Once the wind increases on a certain day, It is very likely that part of the screen frame structure will be damaged or blown away;

[0005] In addition, because the existing screen frame structures are all integrated, and the installation sites are all deserts far away from urban areas, the transportation of this screen frame structure is extremely difficult. Usually, a truck can only transport a small amount of equipment at a time, and its consumption is large. It is very large, which leads to extremely high transportation costs. If it is disassembled and then transported, it needs to prepare a lot of workers on the installation site for assembly. The assembly efficiency and assembly effect are not ideal, so the screen frame is often only small-scale The use of real large-scale promotion is still difficult

[0006] The applicant’s prior application for patent No. 2017109643931, named in the patent literature titled “Mesh Frame for Restoration of Topsoil of Mountain Desert Grassland Degraded Grassland”, records a device that can basically solve the above problems, but it was found in practical applications that the device There are still some defects, mainly that the fixing between the connecting column and the mounting hole is not firm enough, and the fixing method is also relatively complicated. Generally, other common fixing methods are not advisable, because in actual work, the connecting column is often placed in the mounting hole first. , and then move the fixed pile. In the process of moving the fixed pile, the connecting column rotates in the installation hole, and the main body of the filter screen is gradually pulled out. If the common fixing method is adopted, the structural shape of the connecting column and the installation hole is improved. , it is difficult for the connecting column to rotate in the mounting hole, which will add a lot of trouble to the layout work
