Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a high-efficiency mixing device for coal gangue-based artificial soil. Background Technology

[0002] Coal gangue-based artificial soil is a type of artificial soil made primarily from coal gangue, with the addition of specific activators, regulators, and intermediate reagents. It addresses the problem of large-scale coal gangue stockpiling and provides a high-quality soil substitute for soil improvement, artificial planting, and ecological restoration. However, efficient mixing is crucial during production. High-efficiency mixing devices for coal gangue-based artificial soil play a key role in improving production efficiency and quality. These devices are typically equipped with powerful mixing blades. These uniquely designed blades rotate at high speed under motor drive, thoroughly dispersing and mixing the coal gangue and additives. Optimized blade layout and speed control ensure uniform mixing of materials within the device in a short time, significantly improving mixing efficiency. However, complete agitation is often impossible during the mixing process.

[0003] The dual-mixing mechanism in the high-efficiency mixing device for coal gangue-based artificial soil, including blades, rotors, and a motor, has significant advantages in improving mixing efficiency and uniformity. This mechanism consists of two sets of mixing components, each containing a mixing shaft and blades of different shapes. One set of mixing components may have large-sized blades, focusing on generating a large-scale material flow to initially break up large pieces of coal gangue and mix the material at a macroscopic level. The other set of components may be equipped with turbine blades, which use the strong shearing force generated by their high-speed rotation to finely mix the material, allowing the additives to be more evenly integrated with the coal gangue. However, this type of mixing mechanism cannot replace worn or damaged blades, resulting in reduced mixing effect and poor half-effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency mixing device for coal gangue-based artificial soil, which aims to improve the problem that the mixing mechanism in the prior art cannot replace worn and damaged blades, resulting in reduced mixing effect and poor half-mixing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency mixing device for coal gangue-based artificial soil, comprising a box body, a fixing plate fixedly connected to the top of the inner wall of the box body, a motor fixedly connected to the bottom of the fixing plate, a gear I fixedly connected to the bottom of the motor, multiple gear II meshing with the outer wall of the gear I, a connecting block fixedly connected to the bottom of the gear II, a ring I fixedly connected to the lower end of the outer wall of the connecting block, multiple threaded holes I being provided on the top of the ring I, bolts I being threadedly connected to the inner wall of the threaded holes I, rings II being threadedly connected to the lower end of the outer wall of multiple bolts I near the middle, bolts II being threadedly connected to the lower end of the outer wall of bolts I near the edge, a cover plate fixedly connected to the top of the box body, and a replacement mechanism fixedly connected to the top of the box body, the replacement mechanism being used for replacement and installation.

[0006] As a further description of the above technical solution:

[0007] The replacement mechanism includes multiple limiting posts, the bottom of which is fixedly connected to the top of the cover plate. Springs are slidably connected to the outer walls of the limiting posts. Locking posts are fixedly connected to the left and right sides of the top of the cover plate. Fixing rings are slidably connected to the top of the locking posts. Circular grooves are provided at the left and right ends of the fixing rings. Circular holes are provided near the middle on the left and right sides of the fixing rings. The inner walls of the circular holes are slidably connected to the outer walls of the limiting posts.

[0008] As a further description of the above technical solution:

[0009] A rotating rod is fixedly connected to the bottom of the second ring near the middle, and blades are fixedly connected to the outer wall of the rotating rod.

[0010] As a further description of the above technical solution:

[0011] The top of the cover plate is connected to a cylinder near the middle, and a tapered tube is slidably connected to the inner wall of the cylinder.

[0012] As a further description of the above technical solution:

[0013] The top of each box is fixedly connected with multiple threaded rods, and the upper end of the outer wall of each threaded rod is threaded with a threaded cap.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the box is connected to a discharge pipe, and a valve is rotatably connected inside the discharge pipe.

[0016] As a further description of the above technical solution:

[0017] An annular plate is fixedly connected to the lower end of the outer wall of the box, and multiple support columns are fixedly connected to the bottom of the annular plate.

[0018] As a further description of the above technical solution:

[0019] Each of the support columns has a base plate fixedly connected to its bottom, and each base plate has multiple foot pads fixedly connected to its bottom perimeter.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when stirring is required and the blades are worn, first unscrew bolt 2 from bolt 1, then remove bolt 1 from ring 1. At this time, ring 1 and ring 2 are separated. Remove ring 2 with the rotating rod. Then, similarly, install the new rotating rod onto ring 1. Then, rotate bolt 1 back onto the inside of ring 1 and ring 2. Then, rotate bolt 2 back into bolt 1. This achieves the function of timely replacement of worn blades.

[0022] 2. In this utility model, when it is necessary to replace the tapered tube, first press the tapered tube. At this time, the tapered tube will drive the fixing ring to move downward. The fixing ring will then move downward along the limiting post, and then squeeze the spring. At this time, the spring will be compressed, and the circular groove will leave the locking post. The tapered tube will then drive the fixing ring to move downward until the circular groove is locked inside the locking post. At this time, the spring will return to its original state, thus realizing the function of replacing tapered tubes of different sizes and facilitating feeding operations. Attached Figure Description

[0031] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 This utility model provides an embodiment of a high-efficiency mixing device for coal gangue-based artificial soil, comprising a housing 1, a fixing plate 3 fixedly connected to the top of the inner wall of the housing 1, a motor 4 fixedly connected to the bottom of the fixing plate 3, providing a power source for the whole, a gear 5 fixedly connected to the bottom of the motor 4, and multiple gears 6 meshing with the outer wall of the gear 5 for convenient transmission, a connecting block 7 fixedly connected to the bottom of the gear 6, a ring 9 fixedly connected to the lower end of the outer wall of the connecting block 7, multiple threaded holes 10 opened on the top of the ring 9, bolts 8 threadedly connected to the inner wall of the threaded holes 10 for fixed connection, a ring 11 threadedly connected to the lower end of the outer wall of the multiple bolts 8 near the middle, and a bolt 12 threadedly connected to the lower end of the outer wall of the bolts 8 near the edge, a cover plate 18 fixedly connected to the top of the housing 1 for more stable connection, and a replacement mechanism 2 fixedly connected to the top of the housing 1 for replacement and installation;

[0032] Specifically, the housing 1 has a unique internal structure. A sturdy fixing plate 3 is fixedly connected to the top of its inner wall, providing support. The bottom of the fixing plate 3 is firmly connected to the motor 4, ensuring the stability of the motor 4 during operation. The motor 4, as the power source, has a gear 5 fixedly connected to its bottom. This gear 5 is a key part of the entire transmission system. Multiple gears 6 are evenly meshed on the outer wall of gear 5. The coordinated work of these gears 6 ensures smooth and efficient transmission.

A ring 9 is fixedly connected to the lower end of the outer wall of the connecting block 7. Multiple threaded holes 10 are evenly distributed on the top of the ring 9, which facilitates subsequent assembly. Multiple bolts 8 are fixed to the inner wall of the threaded holes 10 by threaded connection. The precise installation of these bolts 8 ensures the stability and reliability of the entire device. Near the middle position of the lower end of the outer wall of the multiple bolts 8, a ring 2 11 is fixed by threaded connection. The design of the ring 2 11 further enhances the structural strength of the device.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The replacement mechanism 2 includes multiple limiting posts 201. The bottom of each limiting post 201 is fixedly connected to the top of the cover plate 18. A spring 202 is slidably connected to the outer wall of the limiting post 201, providing elastic support for the whole. A locking post 203 is fixedly connected to the top left and right sides of the cover plate 18.

At the same time, circular holes 206 are also provided on the left and right sides of the fixing ring 204 near the middle. The inner wall of the circular hole 206 is slidably connected to the outer wall of the limiting post 201, thereby allowing the limiting post 201 to move within a certain range to adapt to different operating requirements.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 A rotating rod 13 is fixedly connected to the bottom of the second ring 11 near the middle, which plays a role in rotation. A blade 14 is fixedly connected to the outer wall of the rotating rod 13. A cylinder 15 is connected to the top of the cover plate 18 near the middle. A tapered tube 16 is slidably connected to the inner wall of the cylinder 15 to facilitate feeding. Multiple threaded rods 19 are fixedly connected to the top of the box 1.

[0036] Specifically, a rotating rod 13 is fixedly connected to the bottom of the second ring 11 near the center. Several blades 14 are fixedly connected to the outer wall of the rotating rod 13. These blades 14 can generate a specific airflow effect when the rotating rod 13 rotates. In addition, a cylinder 15 is connected to the top of the cover plate 18 near the center. A tapered tube 16 is slidably connected to the inner wall of the cylinder 15, so that an adjustable sealing space is formed between the cylinder 15 and the tapered tube 16. In order to further enhance the stability and functionality of the structure, multiple threaded rods 19 are evenly fixedly connected to the top of the box 1. The upper ends of the outer walls of these threaded rods 19 are connected to threaded caps 17 by threads, so that the entire device can be more stable during use and is easier for operators to adjust and maintain.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5The front side of the outer wall of the box 1 is connected to a discharge pipe 20. The discharge pipe 20 is rotatably connected to a valve 21. The lower end of the outer wall of the box 1 is fixedly connected to an annular plate 24, which serves as a connection. The bottom of the annular plate 24 is fixedly connected to multiple support columns 22, which serve as a support. The bottom of the multiple support columns 22 is fixedly connected to a base plate 23. The bottom of the base plate 23 is fixedly connected to multiple foot pads 25 around its perimeter for easy support.

[0038] Specifically, a discharge pipe 20 is connected to the front side of the outer wall of the housing 1. A valve 21 is rotatably connected inside the discharge pipe 20 to control the flow of materials. To ensure the stability and durability of the housing 1, an annular plate 24 is fixedly connected to the lower end of its outer wall. Multiple support columns 22 are fixedly connected to the bottom of the annular plate 24. These support columns 22 are evenly distributed to provide uniform support force. A base plate 23 is fixedly connected to the bottom of the multiple support columns 22. Multiple foot pads 25 are fixedly connected to the bottom of the base plate 23. The foot pads 25 are designed to reduce friction and noise when the equipment contacts the ground, while protecting the ground from damage.

[0039] Working principle: When stirring is required, motor 4 is started first. Motor 4 drives gear 5 to rotate, then gear 5 drives gear 6 to rotate. Gear 6 will then drive connecting block 7 to rotate, and connecting block 7 will drive ring 9 and ring 11 to rotate. Subsequently, rotating rod 13 and blade 14 rotate together. At this time, the two rotating rods 13 inside the housing 1 will rotate in cooperation. When blade 14 is worn, first unscrew bolt 8 from bolt 22, and then remove bolt 8 from ring 9. At this time, ring 9 and ring 11 are separated. Ring 11 is removed along with rotating rod 13. Then, a new rotating rod 13 is installed on ring 9 in the same way. Then, bolt 8 is rotated back into the inside of ring 9 and ring 11. Then, bolt 22 is rotated back into bolt 8. This achieves the function of timely replacement of worn blade 14.

[0040] When the tapered tube 16 needs to be replaced, first press the tapered tube 16. At this time, the tapered tube 16 will drive the fixing ring 204 to move downward. The fixing ring 204 will then move downward along the limiting post 201, and then squeeze the spring 202. At this time, the spring 202 will be compressed, and the circular groove 205 will disengage from the locking post 203. Then the tapered tube 16 and the fixing ring 204 can be removed. Similarly, the new tapered tube 16 can be installed back. Then press the tapered tube 16. At this time, the tapered tube 16 will drive the fixing ring 204 to move downward until the circular groove 205 is locked inside the locking post 203. At this time, the spring 202 will return to its original state. This realizes the function of being able to replace tapered tubes 16 of different sizes, which facilitates the feeding operation.

[0041] 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.
