Description

Technical Field

[0001] This utility model belongs to the field of farmland soil wind erosion measurement technology, and in particular relates to a device that facilitates the measurement of the degree of wind erosion. Background Technology

[0002] Soil wind erosion is the process of soil being stripped, sorted, and transported by wind. It is a major environmental problem faced by arid and semi-arid regions. Soil wind erosion leads to coarser soil texture and deteriorated structure. Strong winds in black soil areas mostly occur in winter and spring, with strong winds and long durations. In addition, the low straw retention and low surface cover after the previous crop harvest lead to dry and loose soil, resulting in severe wind erosion. Therefore, it is necessary to use a soil wind erosion measuring device to measure the amount of soil erosion in black soil farmland. A search revealed that patent application number 202421831966.5 discloses a farmland soil wind erosion measuring device, including a supporting base plate, an adjusting frame set in the middle of the top of the supporting base plate, a fixing block set on one side of the top of the adjusting frame, a sliding rod set at the bottom of the fixing block, a sliding plate set on the outer surface of the sliding rod, a supporting block set on one side of the sliding plate, a sand collection box set on one side of the supporting block, a sand collection box set on the top of the sand collection box, and a supporting spring set in the middle of the top of the sliding plate.

[0003] However, during actual use, the applicant found that the bottom of the sand sifting box used to collect wind-eroded soil particles was fixedly connected to the sand collection box. Due to the lack of a sand-collecting structure, personnel needed to use external tools to remove the wind-eroded soil particles collected inside the sand sifting box little by little from the opening at the top of the sand sifting box, which made the collection of wind-eroded soil particles inconvenient. In view of this, we propose a device that is convenient for measuring the degree of wind erosion. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A device for easily measuring the degree of wind erosion includes a stabilizing base 1. The stabilizing base 1 has a multi-layered plate structure, which increases the contact area with the ground and enhances the stability of the device. A top plate 2 is fixedly connected to the top of the stabilizing base 1, and a supporting column 3 is fixedly connected to the top of the top plate 2. A sand collection box 5 is fixedly connected to the supporting column 3 through a connecting sleeve 4, and several sand collection boxes 5 are evenly spaced along the vertical axis of the supporting column 3. The connecting sleeve 4 is fixedly connected to the rear side of the sand collection box 5 and is fitted and fixed to the supporting column 3. The lower part of the sand collection box 5 is inclined downward. A sand discharge nozzle 51 is provided. A rotating shaft 7 is fixedly connected to the front side of the sand collection box 5. A sand baffle 6 for blocking the port of the sand discharge nozzle 51 is rotatably connected to the front end of the rotating shaft 7. The sand baffle 6 is rotatably connected to the rotating shaft 7 through a bearing. The rear side wall of the sand baffle 6 fits against the port of the sand discharge nozzle 51, which can block the port of the sand discharge nozzle 51 and prevent the wind-eroded soil particles collected inside the sand collection box 5 from leaking out of the sand discharge nozzle 51. A limit pin 8 is movably connected through the sand baffle 6 above the rotating shaft 7. The rear end of the limit pin 8 is elastically inserted into the sand collection box 5 through a return spring 9. In the limiting insertion hole 52 on the front side of the sand box 5, a pull ring 82 is fixedly installed at the front end of the limiting pin 8, and a limiting circular plate 81 is fixedly installed at the rear end of the limiting pin 8. The limiting circular plate 81 elastically abuts against the front side of the sand box 5. A return spring 9 is sleeved on the limiting pin 8, with its front end abutting against the sand baffle 6 and its rear end abutting against the limiting circular plate 81. Through the setting of the limiting pin 8, the sand baffle 6 can be effectively prevented from rotating around the rotating shaft 7, thereby effectively preventing wind-eroded soil particles inside the sand box 5 from being discharged from the sand discharge nozzle 51. The wind-eroded soil particles collected inside the sand collection box 5 will not be squeezed open by the sand discharge nozzle 51, causing the wind-eroded soil particles to spill out. By manually moving the sand discharge nozzle 6 to one side around the rotating shaft 7, the sand discharge nozzle 51 can be moved away from the sand discharge nozzle 51, and the wind-eroded soil particles collected from the sand collection box 5 can be quickly discharged and collected from the sand discharge nozzle 51. The operation is convenient. By inserting the rear end of the limiting pin 8 into the limiting hole 52, the sand discharge nozzle 6 can be limited, effectively preventing the wind-eroded soil particles collected inside the sand collection box 5 from spilling out from the sand discharge nozzle 51.

[0022] A striking element 10 is symmetrically arranged on both sides of the sand-collecting box 5. The striking element 10 includes a spring steel 101, a striking ball 102, and a deflecting handle 103. The striking ball 102 is fixedly connected to the rear end of the spring steel 101, and the deflecting handle 103 is fixedly set on the outer wall of the spring steel 101. The spring steel 101 has a strip-shaped plate structure, and the front end of the spring steel 101 is bent inward and fixedly connected to the outer wall of the sand-collecting box 5. The spring steel 101 has good elasticity and can drive the striking ball 102 towards the sand-collecting box 5. The sand box 5 is reset and moved, and the side wall of the sand box 5 is struck by the striking ball 102. This helps personnel to knock off the wind-eroded soil particles attached to the side wall of the sand box 5, thereby improving the collection of the wind-eroded soil particles. The striking ball 102 is against the outer wall of the sand box 5. The spring steel 101 makes it easy for personnel to knock off the side wall of the sand box 5, thereby improving the collection of the wind-eroded soil particles.

[0023] Working principle: In use, the stabilizing seat 1 can be buried underground, and the top plate 2 can be flush with the ground. Sand-collecting boxes 5 at different heights on the supporting column 3 can collect wind-eroded soil particles. When it is necessary to collect the wind-eroded soil particles, the pull ring 82 can be manually pulled outwards, causing the limiting pin 8 and the limiting circular plate 81 to move backwards, compressing the return spring 9 and causing the rear end of the limiting pin 8 to be pulled out of the limiting insertion hole 52. Then, the sand baffle 6 can be manually moved around the rotating shaft 7, causing the lower part of the sand baffle 6 to move away from the port of the sand discharge nozzle 51. This allows the wind-eroded soil particles collected inside the sand-collecting box 5 to be discharged and collected from the sand discharge nozzle 51. Moving the lever 103 outward causes the rear end of the spring steel 101, along with the striking ball 102, to move outward. Releasing the lever 103 allows the striking ball 102 to reset under the elasticity of the spring steel 101 and strike the sand collection box 5. This knocks off and collects the wind-eroded soil particles attached to the inner wall of the sand collection box 5. After collection, the sand baffle 6 can be reset again, allowing the rear end of the limiting pin 8 to be inserted into the limiting hole 52 under the elastic force of the reset spring 9, thus limiting the sand baffle 6. At this time, the rear side wall of the lower end of the sand baffle 6 can fit tightly against the port of the sand discharge nozzle 51, thus blocking the port of the sand discharge nozzle 51.
