Technical Field
[0001] This utility model relates to the field of soil sieving technology, and in particular to a soil sieving device. Background Technology
[0002] Soil testing refers to the detection and evaluation of the physical, chemical, and biological characteristics of soil through a series of scientific analytical methods and techniques. Soil testing sieving devices are equipment specifically used to screen and separate soil samples. Through soil testing, information such as soil fertility, pollution level, and pH balance can be obtained, providing important basis for rational fertilization, soil improvement, environmental protection, and land planning in agricultural production.
[0003] In existing technologies, soil samples need to be classified and tested during soil analysis to meet specific needs. Manual screening is tedious and prone to errors, and cannot be completed quickly and accurately. Therefore, we propose a sieving device for soil analysis. Utility Model Content
[0004] The purpose of this invention is to provide a sieving device for soil testing, in order to solve the problems mentioned in the background art, such as the cumbersome and error-prone manual screening, which cannot complete the screening work quickly and accurately.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for soil testing, comprising a base and a sieving mechanism, wherein the sieving mechanism includes a sieving box, the sieving box being movably connected to multiple sets of stainless steel screens via multiple sets of slots, a vibrator being fixedly installed at the center of the bottom of the sieving box, and telescopic rods being fixedly installed near the four corners of the bottom of the sieving box, a motor being fixedly connected to the sieving box via a mounting frame, and the motor being connected to a rotating frame via a rotating shaft.
[0006] As a preferred embodiment, the bottom of the vibrator is fixedly installed at the center of the upper surface of the base, and the bottom of the telescopic rod is fixedly installed near the four corners of the upper surface of the base.
[0007] As a preferred embodiment, multiple sets of slots are provided inside the screening box, and multiple sets of stainless steel screens are respectively secured inside the multiple sets of slots. The right side of the screening box is provided with a discharge port corresponding to the slots.
[0008] As a preferred embodiment, the bottom of the mounting frame is fixedly mounted on the back of the screening box, the motor is fixedly mounted on the front of the mounting frame, the rotating shaft is fixedly mounted on the output shaft of the motor, the rotating frame is fixedly mounted on the outer wall of the rotating shaft, and the bottom of the rotating frame abuts against the surface of the stainless steel screen.
[0009] As a preferred embodiment, a material guiding mechanism is provided on the right side of the screening mechanism. The material guiding mechanism includes a base plate, which is fixedly installed on the right side of the base. A vertical rod is fixedly installed on the upper surface of the base plate. A limit hole passes through the side of the vertical rod. A limit rod is inserted into the inside of the limit hole. A discharge pipe is fixedly installed on the inner side of the limit rod. One end of the discharge pipe is fixedly installed on the outer end of the discharge port.
[0010] As a preferred embodiment, the other end of the discharge pipe is connected to a telescopic extension hose.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. Through the set screening mechanism, with the help of the vibration of the vibrator and the extension and retraction of the telescopic rod, the screening box can be driven to shake up and down, causing the soil inside the screening box to move along the stainless steel screen towards the discharge port. The rotating shaft is driven by the motor to rotate, so that the soil rotates with the rotating frame. Soil particles with the appropriate aperture will pass through the corresponding size stainless steel screen, leaving soil particles that fit the aperture to flow out from the discharge port. In this way, the automatic screening can be accurately achieved according to the size of the soil particles, which is both convenient and efficient.
[0013] 2. The material guiding mechanism can limit and lift the discharge pipe by using the limiting holes and limiting rods to prevent the discharge pipe from breaking due to excessive discharge weight. By extending the telescopic hose, soil particles are transported to the collection box, effectively avoiding the problem of inconvenient material collection caused by the limited length of the discharge pipe.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] Please see the appendix Figure 1 - Appendix Figure 4 A soil sieving device includes a base 1 and a sieving mechanism 2. The sieving mechanism 2 includes a sieving box 201, which is movably connected to multiple sets of stainless steel screens 206 via multiple sets of slots 204. A vibrator 202 is fixedly installed at the center of the bottom of the sieving box 201, and telescopic rods 203 are fixedly installed near the four corners of its bottom. A motor 208 is fixedly connected to the sieving box 201 via a mounting frame 207. The motor 208 is connected to a rotating frame 210 via a rotating shaft 209. The bottom of the vibrator 202 is fixedly installed at the center of the upper surface of the base 1, and the bottom of the telescopic rods 203 is fixedly installed... The screen is fixedly installed on the upper surface of the base 1 near the four corners. Multiple sets of slots 204 are opened inside the screening box 201. Multiple sets of stainless steel screens 206 are respectively snapped into the slots 204. The right side of the screening box 201 has a discharge port 205 corresponding to the slots 204. The bottom of the mounting frame 207 is fixedly installed on the back of the screening box 201. The motor 208 is fixedly installed on the front of the mounting frame 207. The rotating shaft 209 is fixedly installed on the output shaft of the motor 208. The rotating frame 210 is fixedly installed on the outer wall of the rotating shaft 209. The bottom of the rotating frame 210 abuts against the surface of the stainless steel screen 206.
[0024] The back of the screening box 201 has a discharge chute. The smallest soil particles after screening will fall to the bottom of the screening box 201 and can be poured out through the discharge chute on the back of the screening box 201. The slot 204 is tilted downward on the right end, so that the soil on the stainless steel screen 206 will slide from left to right under the action of gravity until it flows out from the discharge port 205.
[0025] Specifically, the vibration of the vibrator 202, combined with the extension and retraction of the telescopic rod 203, causes the screening box 201 to shake up and down, so that the soil inside the screening box 201 moves along the stainless steel screen 206 towards the discharge port 205. The motor 208 drives the rotating shaft 209 to rotate, and the soil rotates with the rotating frame 210. Soil particles with the appropriate aperture size will pass through the corresponding size of the stainless steel screen 206, leaving soil particles with the appropriate aperture size to flow out from the discharge port 205. It can accurately and automatically screen according to the size of the soil particles, which is convenient and efficient.
[0026] Example 2:
[0027] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 Furthermore, based on Embodiment 1, a material guiding mechanism 3 is provided on the right side of the screening mechanism 2. The material guiding mechanism 3 includes a base plate 301, which is fixedly installed on the right side of the base 1. A vertical rod 302 is fixedly installed on the upper surface of the base plate 301. A limiting insertion hole 303 passes through the side of the vertical rod 302. A limiting insertion rod 305 is inserted into the inside of the limiting insertion hole 303. A discharge pipe 304 is fixedly installed on the inner side of the limiting insertion rod 305. One end of the discharge pipe 304 is fixedly installed on the outer end of the discharge port 205, and the other end of the discharge pipe 304 is connected to a telescopic extension hose 306.
[0028] The tilt angle of the discharge pipe 304 is consistent with that of the slot 204, which allows soil particles to flow smoothly out of the discharge pipe 304 without clogging. The telescopic extension hose 306 is inserted into the discharge end of the discharge pipe 304, making it easy to replace when the length of the telescopic extension hose 306 is insufficient or damaged.
[0029] Specifically, the discharge pipe 304 can be limited and lifted by the limiting insertion hole 303 and the limiting insertion rod 305 to prevent the discharge pipe 304 from breaking due to excessive discharge weight. The soil particles are transported into the collection box by the extension and retraction of the telescopic extension hose 306, avoiding the problem of inconvenient material collection due to the limited length of the discharge pipe 304.
[0030] Working principle of this utility model: This utility model is a sieving device for soil testing. First, the suitable telescopic extension hose 306 is installed on the discharge pipe 304, and the end is extended into the inside of the collection box. The discharge pipe 304 is limited and lifted by the limiting insertion hole 303 and the limiting insertion rod 305. The vibrator 202 and the motor 208 are turned on, causing the screening box 201 to shake up and down. The telescopic rod 203 extends and retracts back and forth, and the soil is poured in from the upper left of the screening box 201. The rotating shaft 209, driven by the motor 208, drives the rotating frame 210 to scrape the soil, so that soil of different aperture sizes falls from different stainless steel screens 206. Soil particles larger than the stainless steel screen 206 will flow out from the discharge port 205. The last soil particles will fall into the bottom of the screening box 201 and be collected from the discharge trough on the back of the screening box 201.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
