[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] like Figures 1-4 As shown, a wet sieving device for soil aggregates according to an embodiment of the present disclosure is illustrated, comprising:
[0036] The outer casing 1 and the column 2 are fixed to the outer wall of the outer casing 1;
[0037] The screen plate 3 and the discharge assembly 6 are provided. The screen plate 3 is located inside the outer shell 1 and the discharge assembly 6 is located at the bottom of the outer shell 1.
[0038] Top-level screening component 5 is installed on column 2;
[0039] Vibration component 4 is disposed inside the housing 1;
[0040] The vibration assembly 4 includes several fixed plates 4-1, each fixed to the top of the inner wall of the outer shell 1. The surface of the fixed plate 4-1 has a round hole 4-2. A pair of damping springs 4-3 are provided on the surface of the fixed plate 4-1. The upper end of the damping springs 4-3 is connected to a base plate 4-4. A vibration motor 4-5 is provided on the base plate 4-4. A connecting rod 4-6 is provided at the bottom of the base plate 4-4. An outer frame 4-7 is provided at the lower end of the connecting rod 4-6. An inner frame 4-8 is fixedly connected inside the outer frame 4-7. Several connecting rods 4-9 are fixedly connected between the outer frame 4-7 and the inner frame 4-8.
[0041] In some examples, during soil screening, a vibration assembly 4 is designed to accelerate the screening speed for wet soil. This assembly includes several fixed plates 4-1 fixed to the top of the inner wall of the outer casing 1, providing a mounting base for the entire vibration assembly 4. The fixed plates 4-1 have circular holes 4-2 on their surfaces, and a pair of damping springs 4-3 are installed on their surfaces. The upper ends of these springs are connected to the base plate 4-4 and the vibration motor 4-5. The damping springs 4-3 act as buffers and absorb shocks, reducing the vibration transmitted to the outer casing 1 when the vibration motor 4-5 is working, thus ensuring the stability of the equipment. When the vibration motor 4-5 starts, it generates high-frequency vibration, which is transmitted to the connecting rod 4-6 through the base plate 4-4. The bottom of the base plate 4-4 is equipped with… The connecting rod 4-6, connected at its lower end to the outer frame 4-7, serves to transmit vibrations. It transmits the vibrations generated by the vibrating motor 4-5 to the outer frame 4-7 and the inner frame 4-8. The inner frame 4-8, fixedly connected inside the outer frame 4-7, and several connecting rods 4-9 fixedly connecting the outer frame 4-7 and the inner frame 4-8, form a stable frame structure. This frame structure, under vibration, can fully vibrate the wet soil, increasing the gaps between soil particles, accelerating the drainage of water and the separation of different particles, thereby accelerating the screening process. When the vibrating motor 4-5 starts, its high-frequency vibrations are transmitted through the base plate 4-4 and connecting rod 4-6 to the frame structure formed by the outer frame 4-7 and the inner frame 4-8. The outer frame 4-7 and the inner frame 4-8 are fixedly connected by several connecting rods 4-9, forming a rigid support system that ensures the vibration is evenly distributed throughout the screening space. This vibration reduces the adhesion between wet soil particles, widens the gaps between particles, accelerates water infiltration and drainage, and promotes the stratification of soil particles of different sizes due to differences in vibration inertia, thereby achieving better screening efficiency and reducing impurity residue.
[0042] like Figures 1-4As shown, this embodiment proposes a top-level screening component 5 including a telescopic cylinder 5-1, which is fixed inside the column 2. The output end of the telescopic cylinder 5-1 is connected to a crossbeam 5-2. A suction pump 5-3 is installed at the top of the crossbeam 5-2, and a connecting column 5-4 is installed at the bottom of the crossbeam 5-2. A screen hopper 5-5 is installed at the lower end of the connecting column 5-4, and a suction hood 5-6 is installed at the lower end of the connecting column 5-4. The side surface of the suction hood 5-6 is open around the perimeter, and the suction end of the suction pump 5-3 is connected to the suction hood 5-6.
[0043] In some examples, during the screening process of wet soil, a top-level screening component 5 is designed to improve screening efficiency. This component includes a telescopic cylinder 5-1 fixed inside the column 2, which controls the lifting and lowering. The telescopic movement of the cylinder 5-1 controls the lifting and lowering of the crossbeam 5-2. When the cylinder 5-1 extends, the crossbeam 5-2 moves downward, causing the screen bucket 5-5 to approach the wet soil and press against the top of the soil. The screen bucket 5-5 is the main component for screening the wet soil. A suction pump 5-3 is installed at the top of the crossbeam 5-2 to extract the screened portion. The screen bucket 5-5 has a specific screen hole structure, allowing soil particles meeting certain size requirements to pass through the screen holes and enter the screen bucket 5-5 in reverse, thus achieving soil screening. A suction hood 5-6 is located at the lower end of the connecting column 5-4, with an open structure around its side surface, and is connected to the suction pump. The suction end of 5-3 is connected, and when the suction pump 5-3 starts, it can suck away the moisture and some fine particles from the surface of the wet soil through the suction hood 5-6, achieving effective separation. The suction pump 5-3 at the top of the crossbeam 5-2 forms a negative pressure suction system with the suction hood 5-6 through the connecting column 5-4. The annular opening on the side surface of the suction hood 5-6 is in close contact with the wet soil surface, which can simultaneously extract the screened water, fine particles, and residual impurities. When processing wet soil containing mud, the suction system can effectively separate the free water and simultaneously remove impurities such as grass roots and gravel, resulting in a higher purity of the final screened product, which is significantly better than the effect of gravity separation alone in traditional screening processes. In addition, the linkage control between the telescopic cylinder 5-1 and the suction pump 5-3 further optimizes the screening efficiency and impurity removal effect, achieving high-efficiency screening operation.
[0044] like Figures 1-4 As shown, this embodiment proposes a discharge assembly 6 including a docking cover 6-1, which is connected between the screen plate 3 and the inner bottom surface of the outer shell 1. The bottom of both the screen plate 3 and the outer shell 1 are connected to the docking cover 6-1. A pair of second cylinders 6-2 are provided at the bottom of the outer shell 1. A discharge pipe 6-3 is provided at the output end of the second cylinders 6-2. The discharge pipe 6-3 is sealed and slidably fitted with the inner wall of the docking cover 6-1. A discharge auger 6-4 is provided inside the discharge pipe 6-3. An inlet 6-5 is opened around the side surface of the discharge pipe 6-3.
[0045] In some examples, to achieve rapid discharge of the separated soil, a discharge assembly 6 is designed. This assembly includes a docking cover 6-1 connected between the screen plate 3 and the inner bottom surface of the outer shell 1, and is connected to the connection point, so that both ends of the discharge pipe 6-3 are open structures. A pair of second cylinders 6-2 are provided at the bottom of the outer shell 1, and the discharge pipe 6-3 at its output end is sealed and fitted into the docking cover 6-1. The second cylinders 6-2 can control the discharge pipe 6-3 to rise and fall within the docking cover 6-1. After rising, it can enter the soil. The inlet 6-5 around the discharge pipe 6-3 can receive the soil, and the discharge auger 6-4 provided inside can rotate to transport and discharge the soil outward, achieving the discharge effect.
[0046] For example, such as Figure 1 As shown, the entire circumference of the side surface of the sieve 5-5 is a filtration section.
[0047] In some examples, sieve hopper 5-5 is designed to maximize the removal of impurities, thereby accelerating the sieving efficiency and effectiveness.
[0048] For example, such as Figure 3 As shown, the bottom surface of the sieve hopper 5-5 is an inclined structural surface, and the suction hood 5-6 is located at the center of the sieve hopper 5-5.
[0049] In some examples, tilting the structural surface helps the suction hood 5-6 located at the center to extract impurities.
[0050] For example, such as Figure 3 As shown, both the inner frame 4-8 and the outer frame 4-7 are circular structures.
[0051] In some examples, the coverage area of the inner frame 4-8 and the outer frame 4-7 inside the outer shell 1 is increased by using a ring-shaped structure.
[0052] In actual use: Place the wet soil to be screened on the screen plate 3 inside the outer shell 1, start the vibration motor 4-5 of the vibration component 4, and the vibration is transmitted to the outer frame 4-7 and inner frame 4-8 through the bottom plate 4-4 and connecting rod 4-6 to vibrate and screen the soil. Start the telescopic cylinder 5-1 of the top screening component 5 to bring the screen bucket 5-5 close to the soil. The suction pump 5-3 sucks the surface moisture and fine particles of the soil through the suction hood 5-6. The screen bucket 5-5 screens the soil. After screening, start the second cylinder 6-2 of the discharge component 6 to raise the discharge pipe 6-3 to access the soil. The discharge auger 6-4 rotates to introduce the soil through the inlet 6-5 and transport it outward for discharge.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
