Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil screening device for soil detection. Background Art

[0002] When testing the soil, it is necessary to screen the soil through a screening device, mainly to grade and screen the particles of different sizes in the soil. It is usually composed of components such as a screen, a vibration mechanism and a supporting structure, and the soil is graded and screened through screens of different apertures.

[0003] A soil screening device for soil detection disclosed in a Chinese patent with publication number CN219233010U includes a distributor, a controller is provided on the surface of the distributor, a material pipe is fixedly connected to the upper surface of the distributor, and a threaded rod is fixedly connected to the upper surface of the distributor. The utility model allows the operator to put soil into the third sieve plate, cover the top cover, fix the fixed plate by nuts, and start the motor to rotate through the controller. The holes of the third sieve plate are larger than the holes of the second sieve plate, and the holes of the second sieve plate are larger than the holes of the first sieve plate. The soil is screened by high-speed rotation, and the soil at each sieve plate is inconsistent. The soil is finally screened into the third sieve plate, and the soil is taken out by opening the top cover through the nut. The first sieve plate, the second sieve plate and the third sieve plate are taken out by rotating the threaded nails, and the soil is screened by the first sieve plate, the second sieve plate and the third sieve plate, thereby increasing the use efficiency.

[0004] In the process of implementing this application, the inventor found that there are at least the following problems in this technology: although the above technical solution can improve the efficiency of graded screening, in actual use, since the top cover is pressed by a fixed plate and then fixed by a nut and a threaded rod, the vibration amplitude of the screen plate is small, affecting the screening effect, and when loading and unloading, it is necessary to twist the nut to disassemble and assemble the top cover in order to take out the screened soil. The process is rather cumbersome, and therefore, further improvements can be made. Utility Model Content

[0005] To solve the above-mentioned problems, the utility model provides the following technical solutions: a soil screening device for soil detection, comprising a base, a multi-layer stacked screening box and a sealing cover located on the top of the topmost screening box, a mounting groove is opened in the top of the base, a spring is fixedly installed in the mounting groove, a flat plate is fixedly installed on the top of the spring, the outer edge of the flat plate has four protrusions arranged in an array, the spring is fixedly installed on the bottom side of the protrusion, a mounting block is fixedly installed at the center of the bottom side of the flat plate, a dual-axis motor is fixedly installed on the bottom of the mounting block, counterweights are fixedly installed on one end of the output shafts on both sides of the dual-axis motor, support rods are fixedly installed on the top side of the flat plate and on both sides of the screening box, a plurality of jacks are opened inside the support rods, and a convenient positioning plate assembly is provided on the outside of the support rods and directly above the sealing cover.

[0006] As an optimization, the spring supports the flat plate at the bottom side of the protruding part of the flat plate, and the support rod is located on the flat plate and can vibrate along with the flat plate. By starting the dual-axis motor, the counterweight block is driven to rotate. At the same time, since the spring supports the flat plate, the flat plate is driven to vibrate, so the soil in the screening box is graded and screened, and since the support rod vibrates along with the screening box, the vibration amplitude is not affected.

[0007] As an optimization, the convenient positioning plate assembly includes a pressure plate arranged directly above the sealing cover, support plates are fixedly installed on both sides of the pressure plate, a sleeve is fixedly installed on the middle of the support plate, and the sleeve is slidably sleeved on the outside of the support rod, a sliding groove is opened inside the support plate, an insertion rod is inserted into the inside of the sliding groove, a slide plate is fixedly installed on the outside of the insertion rod located in the sliding groove, a compression spring is fixedly installed between the slide plate and the inner wall of the sliding groove, and a pull handle is fixedly installed on the end of the insertion rod located outside the sliding groove.

[0008] As an optimization, a through hole is opened through the middle of the sleeve, and the outer diameter of the insertion rod is the same as the inner diameter of the support rod.

[0009] As an optimization, the plug rod passes through the middle hole of the sleeve, and the plug rod is inserted into the socket. By inserting one end of the plug rod into the socket, it will limit the support plate, and then press the pressure plate on the top side of the sealing cover, which is convenient for positioning the screening box.

[0010] As an optimization, the slide plate is slidably connected in the slide groove, and the compression spring is sleeved on the outside of the insertion rod. By pulling out the support rod by pulling out the insertion rod, the slide plate will be driven to slide inside the slide groove, and the compression spring will be compressed at the same time, and then the slide plate will be reset by the compression spring, and the insertion rod will be reinserted into the appropriate support rod.

[0011] As an optimization, the outer side of the pull handle is provided with a pattern that increases friction, making it convenient for the operator to pinch the pull handle to lift the insertion rod.

[0012] The beneficial effects of the utility model are:

[0013] 1. The soil screening device for soil detection drives the counterweight to rotate by starting the dual-axis motor, and the flat plate is supported by a spring, which will cause the flat plate to vibrate, so that the soil in the screening box will be screened downward step by step with the vibration, and because the support rod is located on the flat plate, it will vibrate with the screening box, so that the screening efficiency will not be reduced due to the fixed setting affecting the vibration amplitude.

[0014] 2. The soil screening device for soil detection uses the elastic force of the compression spring to ensure that the insertion rod is always inserted into the insertion hole to limit the support plate without external force, so that the pressure plate presses on the sealing cover to position the screening box. The insertion rod can be pulled out of the insertion hole by pulling the handle, and then the support plate is no longer limited. At this time, the support plate can be moved up and down to adjust the position, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
