Description
Technical Field
[0001] This utility model relates to the field of stone grinding technology, and in particular to an integrated stone grinding and screening device. Background Technology
[0002] The integrated grinding and screening equipment for coating preparation is a specialized integrated mechanical equipment for coating production. It achieves efficient processing of coating raw materials by integrating crushing, grinding and screening functions. In the process of material processing, it usually needs to go through grinding and screening steps. Grinding uses abrasive particles coated or embedded on grinding tools. The grinding tools and workpieces are subjected to fine processing of the surface through relative movement under certain pressure. After grinding, the material is then transported to screening equipment for filtration.
[0003] Chinese Patent Publication No. CN209829150U discloses an integrated processing device for grinding and sieving Panax notoginseng powder, including a grinding head, a processing box, and a universal ball. The bottom of the universal ball is fixedly connected to the top of the grinding head. A collection box is slidably installed at the bottom of the processing box. A grinding chamber is fixedly connected to the middle of the processing box cavity. The surface of the grinding head and the surface of the grinding chamber are in contact with each other. A screen is embedded in the bottom of the grinding chamber. A universal ball groove is opened at the top of the grinding chamber. The outer surface of the universal ball is in rolling contact with the inner surface of the universal ball groove. A motor is fixedly installed at the top of the processing box, and a spur gear is fixedly connected to the surface of the motor spindle. This utility model has the advantage of being able to fully grind Panax notoginseng powder, solving the problem that during the grinding process, only the herbs in the upper part of the grinding chamber can be turned over, while the herbs at the bottom of the grinding chamber always accumulate at the bottom, resulting in uneven particle size and unsatisfactory grinding effect.
[0004] The above-mentioned existing technical solutions have the following shortcomings: In use, the processing device has a relatively simple function. When grinding materials by setting a grinding head, it is inconvenient to screen the ground materials and cannot achieve the screening of ground materials, thus failing to achieve the screening purpose. Moreover, it is inconvenient to achieve functional diversity, making the above-mentioned device less applicable and inconvenient to save costs. Therefore, it is necessary to make corresponding improvements. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated stone grinding and screening device, comprising an equipment box and a servo motor, wherein the top of the equipment box is fixedly connected to the servo motor via a support plate, and a cleaning door is movably connected to the outside of the equipment box via a fixed seat;
[0007] The bottom of the equipment box is provided with a discharge port, and the inside of the equipment box is provided with a grinding groove. The output shaft end of the servo motor is fixed with a connecting rod, and a conveying assembly is sleeved on the outside of the connecting rod. A grinding block is fixed at the bottom of the connecting rod. A connecting shaft passes through the inside of the conveying assembly, and a driving gear is sleeved on the outside of the connecting shaft. A driven gear meshes with one side of the driving gear, and a fixed rod passes through the inside of the driven gear. A belt assembly is sleeved on the outside of the fixed rod, and a fixed shaft passes through the inside of the belt assembly. A transport assembly is sleeved on the outside of the fixed shaft, and a rotating shaft passes through the inside of the transport assembly. The inside of the equipment box is provided with a grinding base plate, and a movable rod is fixed on one side of the grinding base plate. The inside of the equipment box is provided with a first screening screen and a second screening screen.
[0008] Preferably, both the rotating shaft and the fixed shaft are fitted with striking blocks, and the bottom of the first screening screen and the second screening screen are fixed with connecting blocks.
[0009] Preferably, one side of the first screening screen is movably connected to one side of the equipment box via a hinge seat, and one side of the second screening screen is movably connected to the other side of the equipment box via a movable seat.
[0010] Preferably, a slider is fixed to the bottom of the grinding base plate, and sliding rods are provided on both sides inside the equipment box, with the slider and the sliding rods being movably connected.
[0011] Preferably, the transport assembly consists of a rotating wheel, a conveying wheel, and a conveyor belt. The rotating wheel is sleeved on the outside of the rotating shaft, the conveying wheel is sleeved on the outside of the fixed shaft, and a conveyor belt connects the rotating wheel and the conveying wheel.
[0012] Preferably, the conveying assembly consists of a rotating wheel, a movable wheel, and a conveyor belt.

The transport wheel is sleeved on the outside of the fixed rod, the auxiliary wheel is sleeved on the outside of the fixed shaft, and the first belt connects the transport wheel and the auxiliary wheel.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the integrated stone grinding and screening equipment facilitates the grinding of the stone, improves the grinding effect, and facilitates the screening of the ground material, thereby improving the utilization rate of the stone for use in coating preparation;
[0015] By activating the servo motor, the connecting rod drives the conveyor assembly to rotate, causing the rotating wheel, movable wheel, and conveyor belt to cooperate, which in turn causes the connecting shaft to drive the drive gear to rotate. This meshes between the drive gear and the driven gear, which in turn causes the driven gear to drive the fixed rod to rotate.

This causes the fixed shaft and rotating shaft to drive the striking blocks to rotate, which in turn causes the striking blocks to strike the connecting block as they rotate.
[0016] Because one side of the first screening screen is movably connected to one side of the equipment box via a hinge seat, and one side of the second screening screen is movably connected to the other side of the equipment box via a movable seat, it is convenient to drive the first and second screening screens to move up and down, so that the first and second screening screens can filter and screen the incoming material, thereby improving the screening effect of the integrated equipment for coating preparation. It also realizes that different motion structures can be driven by a single drive component, which can improve the functionality of the integrated stone grinding and screening equipment and is conducive to energy saving.
[0017] By pulling the movable rod outward, the movable rod drives the grinding base plate to move horizontally, so that the slider can be supported and guided on the sliding rod. This facilitates the horizontal movement of the grinding base plate, allowing the ground material inside the grinding tank to fall into the equipment box for screening. Attached Figure Description

[0026] Please see Figures 1-5 The present invention provides the following technical solution:
[0027] Example 1
[0028] To address the problem that existing integrated equipment is inconvenient for grinding and screening stone materials, the following solution is disclosed. Please refer to the following for details. Figure 1 , Figure 3 , Figure 4 , Figure 5A stone grinding and screening integrated device includes an equipment box 1 and a servo motor 2. The servo motor 2 is fixedly connected to the top of the equipment box 1 via a support plate. A grinding groove 4 is provided inside the equipment box 1. A connecting rod 5 is fixed to the output shaft end of the servo motor 2, and a conveying assembly 7 is sleeved on the outside of the connecting rod 5. A grinding block 6 is fixed to the bottom of the connecting rod 5. A connecting shaft 8 passes through the inside of the conveying assembly 7, and a drive gear 9 is sleeved on the outside of the connecting shaft 8. A driven gear 10 meshes with one side of the drive gear 9, and a fixed rod 11 passes through the inside of the driven gear 10. A belt assembly 21 is sleeved on the outside of the fixed rod 11, and a fixed shaft 12 passes through the inside of the belt assembly 21. A transport assembly 13 is sleeved on the outside of the fixed shaft 12, and a rotating shaft 14 passes through the inside of the transport assembly 13. A first screening screen 18 and a second screening screen 19 are respectively provided inside the equipment box 1. A striking device is sleeved on the outside of both the rotating shaft 14 and the fixed shaft 12. Block 17, connecting block 20 is fixed to the bottom of the first screening screen 18 and the second screening screen 19. One side of the first screening screen 18 is movably connected to one side of the equipment box 1 through a hinge seat. One side of the second screening screen 19 is movably connected to the other side of the equipment box 1 through a movable seat. The transport assembly 13 is composed of a rotating wheel, a conveying wheel and a conveyor belt. A rotating wheel is sleeved on the outside of the rotating shaft 14. A conveying wheel is sleeved on the outside of the fixed shaft 12. A conveyor belt is connected between the rotating wheel and the conveying wheel. The transport assembly 7 is composed of a rotating wheel, a movable wheel and a transport belt. A rotating wheel is sleeved on the outside of the connecting rod 5. A movable wheel is sleeved on the outside of the connecting shaft 8. A conveyor belt is connected between the rotating wheel and the movable wheel. The belt assembly 21 is composed of a transport wheel, an auxiliary wheel and a first belt. A transport wheel is sleeved on the outside of the fixed rod 11. An auxiliary wheel is sleeved on the outside of the fixed shaft 12. A first belt is connected between the transport wheel and the auxiliary wheel.
[0029] In this embodiment, during use, the grinding material is placed inside the grinding tank 4. The servo motor 2 is activated, causing the connecting rod 5 to rotate. The connecting rod 5 then rotates the grinding block 6, allowing the grinding block 6 to grind the grinding material inside the grinding tank 4. The connecting rod 5 also rotates the conveying assembly 7, causing the rotating wheel, movable wheel, and conveyor belt to cooperate. This causes the connecting shaft 8 to rotate the drive gear 9, resulting in meshing between the drive gear 9 and the driven gear 10. The driven gear 10 then rotates the fixed rod 11, which in turn rotates the belt assembly 21, causing the conveyor wheel, auxiliary wheel, and first belt to cooperate. This, in turn, causes the fixed shaft 12 to rotate. Simultaneously, the rotating wheel, conveyor wheel, and conveyor belt cooperate with each other. The rotating shaft 12 and the rotating shaft 14 rotate synchronously, causing the fixed shaft 12 and the rotating shaft 14 to drive the striking block 17 to rotate. The striking block 17 then strikes the connecting block 20 as it rotates. Since one side of the first screening screen 18 is movably connected to one side of the equipment box 1 via a hinge seat, and one side of the second screening screen 19 is movably connected to the other side of the equipment box 1 via a movable seat, it is convenient to drive the first screening screen 18 and the second screening screen 19 to move up and down. This allows the first screening screen 18 and the second screening screen 19 to filter and screen the incoming material, improving the screening effect of the integrated equipment for coating preparation. Furthermore, it enables different motion structures to move using a single driving component, improving the functionality of the integrated stone grinding and screening equipment and contributing to energy conservation.
[0030] Example 2
[0031] This embodiment differs from Embodiment 1 in that it utilizes the grinding base plate 15 to facilitate material feeding, allowing for subsequent sieving of the ground material for coating preparation. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 2 The equipment box 1 has a cleaning door movably connected to the outside of the box via a fixed seat. The bottom of the equipment box 1 has a discharge port 3. The inside of the equipment box 1 has a grinding base plate 15, and a movable rod 16 is fixed to one side of the grinding base plate 15. A slider is fixed to the bottom of the grinding base plate 15. Sliding rods are provided on both sides inside the equipment box 1. The slider and the sliding rod are movably connected.
[0032] In this embodiment, during use, after the stone is ground, the movable rod 16 is pulled outward, causing the movable rod 16 to drive the grinding base plate 15 to move horizontally. This allows the slider to support and guide the movement on the sliding rod, facilitating the horizontal movement of the grinding base plate 15. This allows the ground material inside the grinding tank 4 to fall into the equipment box 1 for screening. Finally, the ground material is discharged through the discharge port 3 for use in coating preparation. Furthermore, a cleaning door is provided on the outside of the equipment box 1, making it easy to open the cleaning door to collect and clean the residue on the first screening screen 18 and the second screening screen 19 for subsequent use.
