Description

Technical Field

[0001] This utility model relates to the field of earthen site restoration, and in particular to a raw soil treatment device for earthen site restoration. Background Technology

[0002] In the restoration of earthen sites, raw soil is required. Raw soil refers to the original natural deposited soil layer that has not been disturbed by human intervention. The characteristics of raw soil are strong cohesion. Raw soil is a three-phase system composed of solid soil particles, water, and gas. Solid soil particles are the main body of the soil, accounting for about 50% of the soil volume. The pores between solid particles are occupied by gas and water. However, raw soil tends to clump together during use. The traditional method is to break up these clumps, but it is necessary to ensure that the particle size distribution of the raw soil is not damaged. Therefore, tools such as wooden paddles are used to break up the clumps. This method is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0003] (1) Technical problem to be solved: How to realize a soil treatment equipment that can both disperse the clumps of raw soil and not damage the particle size distribution of the raw soil.

[0004] (2) The technical solution adopted by this utility model is as follows:

[0005] A raw soil treatment device for the restoration of earthen sites includes a frame. A soil grinding device and a screening machine are arranged sequentially from top to bottom on the frame. The soil grinding device includes a grinding disc, which is fixed to the frame. A discharge port is located in the center of the grinding disc, and the inlet of the screening machine is located directly below the discharge port. A grinding roller is installed on the top of the grinding disc. A soft layer is provided on the top surface of the grinding disc, and a second soft layer is provided on the curved surface of the grinding roller. A drive shaft is coaxially rotatably connected to the grinding disc. A transmission shaft is coaxially installed above the grinding disc, perpendicular to the drive shaft, with its lower end fixed to the drive shaft. The transmission shaft is rotatably connected to the frame. A drive motor is installed on the top of the frame, and its output shaft is coaxially fixed to the transmission shaft. An inclined scraper for guiding the material on the grinding disc to the discharge port is connected to the drive shaft via a connecting rod. A baffle cylinder is provided at the edge of the grinding disc.

[0006] A further technical solution is that both the first soft layer and the second soft layer are made of rubber.

[0007] A further technical solution is that the grinding rollers include two symmetrical about the center of the grinding disc, and the drive shaft corresponding to the other grinding disc is provided with an inclined scraper for guiding the material at the edge of the grinding disc to the center of the grinding disc.

[0008] A further technical solution involves installing a baffle cylinder at the edge of the grinding disc.

[0009] A further technical solution is that the roller has a shaft hole in the middle, a bushing is fixed inside the shaft hole, the drive shaft passes through the bushing, a radial clearance is left between the bushing and the drive shaft, and two limit nuts are provided on the drive shaft, with the two limit nuts respectively located on both sides of the roller.

[0010] (3) Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: By setting up a soil grinding device and a screening machine, after placing the raw soil on the grinding disc of the soil grinding device, the drive motor can be started to drive the grinding roller to roll on the grinding disc. When the grinding disc rolls, it will break up the raw soil clumps on the grinding disc. Since there is a soft layer 1 on the top of the grinding disc and a soft layer 2 on the curved surface of the grinding roller, the grinding roller and the grinding disc are essentially in soft contact, which can ensure that the soil particles will not be crushed. The drive shaft is connected by a connecting rod to an inclined scraper for guiding the material on the grinding disc to the discharge port, which can scrape the ground soil into the discharge port. Then the raw soil falls into the feed port of the screening machine, and qualified soil particles are screened out by the screening machine. Unqualified soil particles are returned for re-grinding. Thus, a soil treatment device that can both break up the raw soil clumps and not damage the raw soil particle size distribution is realized. Compared with the traditional method, it can improve efficiency and achieve the purpose of saving time and labor. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figures 1-3As shown. A raw soil treatment device for the restoration of earthen sites includes a frame 1. A soil grinding device and a screening machine 2 are arranged sequentially from top to bottom on the frame 1. The soil grinding device includes a grinding disc 3, which is fixed to the frame 1. A discharge port 4 is provided in the middle of the grinding disc 3. The feed port 5 of the screening machine 2 is located directly below the discharge port 4. A grinding roller 6 is provided on the top of the grinding disc 3. A soft layer 7 is provided on the top surface of the grinding disc 3, and a soft layer 8 is provided on the curved surface of the grinding roller 6. A drive shaft 9 is coaxially rotatably connected to the grinding disc 3. A transmission shaft 10 is coaxially arranged above the grinding disc 3. The transmission shaft 10 is perpendicular to the drive shaft 9, and the lower end of the transmission shaft 10 is fixed to the drive shaft 9. The transmission shaft 10 is rotatably connected to the frame 1. A drive motor 11 is provided on the top of the frame 1. The output shaft of the drive motor 11 is coaxially fixed to the transmission shaft 10. An inclined scraper for guiding the material on the grinding disc 3 to the discharge port 4 is connected to the drive shaft 9 through a connecting rod 12.

[0016] In use, raw soil is fed onto the millstone 3 via an existing screw conveyor or manually. The drive motor 11 is started, and the drive motor 11 drives the transmission shaft 10 to rotate. The drive shaft 9 then drives the millstone 3 to roll on the millstone 3. When the millstone 3 rolls, it breaks up the clumps of raw soil on the millstone 3. Since the millstone roller 6 and the millstone 3 have soft contact, it can ensure that the particles in the raw soil are not damaged. The broken soil is scraped into the discharge port 4 by the inclined scraper and falls into the screen 2 for screening. The screen 2 is a vibrating screen. The vibrating screen is an existing vibrating screen, which includes a base. The screen groove is connected to the base by spring shock absorption. A vibrating motor is installed on the screen groove. The top of the screen groove has a feed port 5 located below the discharge port 4. The transmission shaft 10 is connected to the frame 1 by a thrust bearing, so that the frame 1 can provide support for the transmission shaft 10.

[0017] Both soft layer 7 and soft layer 8 are made of rubber. Soft layer 7 is connected to the grinding disc 3 by screws, and soft layer 8 is connected to the grinding roller 6 by screws.

[0018] The grinding rollers 6 include two symmetrical about the center of the grinding disc 3. The drive shaft 9 corresponding to the other grinding roller 6 is equipped with an inclined scraper 13 for guiding the material at the edge of the grinding disc 3 to the inner side. The material is fed after the two grinding rollers 6 rotate one revolution. The feeding position only needs to be in front of the inclined scraper 13. Two grinding rollers 6 are more efficient, and two grinding rollers 6 are preferred.

[0019] The roller 6 has a shaft hole 14 in the middle, and a bushing 15 is fixed inside the shaft hole 14. The drive shaft 9 passes through the bushing 15, and a radial clearance 16 is left between the bushing 15 and the drive shaft 9, allowing the roller 6 to float radially. The roller 6 breaks the soil by its own weight when rotating. Two limit nuts 17 are provided on the drive shaft 9, respectively located on both sides of the roller 6. The axial position of the roller 6 can be limited by the limit nuts 17. If the drive shaft 9 and the roller 6 are fully engaged, a certain clearance needs to be left between the roller 6 and the grinding disc 3. This clearance distance is fixed to prevent the solid soil particles from being damaged.

[0020] A material retaining cylinder 18 is provided at the edge of the millstone 3, which can retain soil and facilitate the feeding of materials onto the millstone 3.

[0021] The above are merely preferred embodiments of this utility model.
