Description

Technical Field

[0001] This utility model relates to the technical field of soil testing devices, specifically a soil grinding device. Background Technology

[0002] Currently, soil contaminant testing requires on-site collection in advance. The collected soil may contain some impurities, such as small stones. Therefore, the collected soil needs to be pretreated. The collected soil needs to be air-dried, impurities removed, crushed and ground, and sieved to ensure that the final particle size of the dried soil is less than 100 mesh. During crushing and grinding, the soil is generally placed in a grinding device for grinding.

[0003] The invention patent with publication number CN116698542A discloses an ultrafine soil ball mill. It uses the rotation of a tooling disc and multiple tooling cylinders rotatably connected to the tooling disc to fix the ball milling cylinders inside the tooling cylinders. Soil and grinding balls are placed inside the ball milling cylinders, and grinding is achieved by the rotation of the tooling disc and the rotation of the tooling cylinders. However, the structure of fixing the ball milling cylinders inside the tooling cylinders in this application is complicated, and four ball milling cylinders need to be rotated and fixed each time. When performing large-scale ball milling, a lot of time is wasted. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a soil grinding device.

[0005] This utility model is achieved through the following technical solution: a soil grinding device is provided, including a cabinet, a tooling plate rotatably connected to the cabinet, and a plurality of tooling cylinders evenly distributed circumferentially along the rotating axis of the tooling plate. The tooling cylinders are rotatably connected to the tooling plate through tooling cylinder rotating shafts. Grinding cylinders and pressure caps located above the grinding cylinders are installed inside the tooling cylinders. A plurality of vertically elongated holes are evenly distributed circumferentially on the grinding cylinders, and centrifugal pressure plates are hinged in the vertically elongated holes.

[0006] As an optimization, the cabinet is equipped with a motor that drives the tooling disc to rotate, a planetary gear is fixedly connected to the rotating shaft of the tooling cylinder, and a fixed gear is fixedly connected to the cabinet. Multiple planetary gears are evenly distributed around the fixed gear and mesh with the fixed gear.

[0007] As an optimization, the tooling tray is rotatably connected to the cabinet via a tooling tray shaft. The tooling tray shaft passes through the cabinet and is connected to the motor. A fixing sleeve is fixedly connected to the tooling tray shaft insertion hole on the cabinet, and the fixing gear is fixedly connected to the outer ring of the fixing sleeve.

[0008] As an optimization, the lower end face of the pressure cap is provided with a conical ring that is inserted into the outer ring of the grinding cylinder.

[0009] As an optimization, a handle is fixedly attached to the upper end of the pressure cap.

[0010] As an optimization, the cabinet is equipped with a touch screen.

[0011] The beneficial effects of this utility model are as follows: The soil grinding device of this utility model uses a pressure cap to press the grinding cylinder, so that the conical ring is inserted between the grinding cylinder and the tooling cylinder to achieve the positioning of the grinding cylinder. The centrifugal force generated by the rotation of the tooling cylinder drives the lower end of the centrifugal pressure plate to swing outward, thereby causing the upper end of the centrifugal pressure plate to swing inward and press against the pressure cap, preventing the pressure cap from moving upward. This utility model achieves the pressing effect through centrifugal force, thereby eliminating the need for manual fixing and improving the grinding efficiency. Attached Figure Description

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] like Figures 1-9 As shown, the present invention provides a soil grinding device, which includes a cabinet 2, which is a high and low cabinet placed on the ground. The high cabinet of the cabinet 2 is equipped with a touch screen 1, which is used to control the start and stop operation of the system.

[0025] The upper surface of the lower cabinet of cabinet 2 is flat, and a tooling tray 3 is rotatably connected to it. The tooling tray 3 is a horizontally rotating disc. A tooling tray rotating shaft 5 is fixed to the center of the lower end of the tooling tray 3. The tooling tray rotating shaft 5 is rotatably connected to the cabinet 2. The cabinet 2 is equipped with a motor that drives the tooling tray 3 to rotate. The tooling tray rotating shaft 5 passes through the cabinet 2 and is connected to the motor. The motor is a variable frequency motor, which can control the rotation speed.

[0026] Multiple tooling cylinders 4 are evenly distributed around the circumference of the tooling disc 3. In this embodiment, four tooling cylinders 4 are provided. The tooling cylinder 4 is an open cylinder with an inner diameter larger than the outer diameter of the grinding cylinder 13. The grinding cylinder 13 is placed inside the tooling cylinder 4. The grinding cylinder 13 is formed by the threaded connection of the cylinder body and the cylinder cover, and is filled with grinding balls.

[0027] A tooling cylinder shaft 9 is fixedly connected to the center of the lower end of the tooling cylinder 4. The tooling cylinder shaft 9 passes through the tooling disk 3, and the tooling cylinder 4 is rotatably connected to the tooling disk 3 through the tooling cylinder shaft 9. A planetary gear 7 is fixedly connected to the lower end of the tooling cylinder shaft 9. A fixed gear 6 is fixedly connected to the cabinet 2. A fixed sleeve 8 is fixedly connected to the tooling disk shaft insertion hole on the cabinet 2. The fixed gear 6 is fixed to the outer ring of the fixed sleeve 8, so that the fixed gear 6 is coaxial with the tooling disk 3. Multiple planetary gears 7 are evenly distributed around the fixed gear 6 and all mesh with the fixed gear 6. The diameter of the planetary gears 7 is smaller than the diameter of the fixed gear 6.

[0028] To fix the grinding cylinder 13 within the tooling cylinder 4, a pressure cap 10 is installed above the grinding cylinder 13 inside the tooling cylinder 4. The outer diameter of the pressure cap 10 is equal to the inner diameter of the tooling cylinder 4, and a handle 11 is fixedly connected to the upper end of the pressure cap 10. A conical ring 12 is provided on the lower end face of the pressure cap 10 to insert into the outer ring of the grinding cylinder 13, such as... Figure 6 As shown, the conical ring 12 is inserted between the grinding cylinder 13 and the tooling cylinder 4 to position the grinding cylinder 13 and prevent it from moving.

[0029] To achieve the pressing of the cover 10, the grinding cylinder 13 has multiple circumferentially distributed vertical elongated holes, and a centrifugal pressing plate 14 is hinged in each of the vertical elongated holes. The centrifugal pressing plate 14 is a vertical strip, and the hinge axis between the centrifugal pressing plate 14 and the vertical elongated hole is located near the upper end of the centrifugal pressing plate 14. Thus, the lower end of the centrifugal pressing plate 14 swings outward through centrifugal force, and the upper end of the centrifugal pressing plate 14 swings inward to press the cover 10.

[0030] How to use this utility model:

[0031] When in use, open the cover of the grinding cylinder 13, put in the soil to be ground and the grinding balls, then tighten the cover, place the grinding cylinder 13 in the tooling cylinder 4, then put in the pressure cap 10 and press it down hard so that the conical ring 12 is inserted between the grinding cylinder 13 and the tooling cylinder 4 to achieve the positioning of the grinding cylinder 13.

[0032] The motor is started by controlling the touch screen 1. The motor drives the tooling plate 3 to rotate through the tooling plate shaft 5. The planetary gear 7 of the tooling cylinder shaft 9 meshes with the fixed gear 6, thereby driving the tooling cylinder 4 to rotate. This realizes the revolution and rotation of the grinding cylinder 13, realizing internal grinding. The centrifugal force generated by the rotation of the tooling cylinder 4 drives the lower end of the centrifugal pressure plate 14 to swing outward, thereby causing the upper end of the centrifugal pressure plate 14 to swing inward and press against the pressure cover 10 to prevent the pressure cover 10 from moving upward.

[0033] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
