In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the impeller of the utility model based on a mine stone crusher in conjunction with the accompanying drawings.

[0034] like Figure 1-7 As shown, the utility model is an impeller based on a mining stone crusher, including a lower guard plate 1 and an upper guard plate 2 located directly above the lower guard plate 1. The upper surface of the lower guard plate 1 and the lower surface of the upper guard plate 2 are both provided with wear-resistant plates. By installing wear-resistant plates on the lower guard plate 1 and the upper guard plate 2, the impeller body can be effectively protected from the impact of materials, reduce wear, and increase the service life of the impeller. A feed port 3 is provided in the middle part of the surface of the upper guard plate 2, and a dividing cone 6 detachably connected thereto is provided in the middle part of the upper surface of the lower guard plate 1, and the dividing cone 6 is fixedly connected to the lower guard plate 1 around by fixings, and the fixings include a mounting block 10, and the side walls of the mounting block 10 are provided with plug posts 11, and the side walls around the dividing cone 6 are provided with four plug holes 9 distributed in a circular array, and the size of the plug posts 11 matches the size of the plug holes 9, and the upper surface of the mounting block 10 is provided with a through hole 12, and the upper surface of the lower guard plate 1 is provided with four fixing holes 1 distributed one-to-one with the through holes 12. 4. Bolts are arranged between the through hole 12 and the fixing hole 14. When the sand making machine is working, the dividing cone 6 is the first part that the material contacts. It is subjected to repeated impact and extrusion by the material, resulting in wear on the surface of the dividing cone 6. Severe wear will affect the uniformity of material distribution. Therefore, the dividing cone 6 needs to be regularly maintained or replaced. In order to facilitate the disassembly and installation of the dividing cone 6, a fixing part of the dividing cone 6 is provided. When the dividing cone 6 needs to be replaced, the bolts of the fixed mounting block 10 are removed, and the plug 11 on the mounting block 10 is withdrawn from the plug hole 9, and the dividing cone 6 can be disassembled. The operation is simple and quick. The bottom of the dividing cone 6 is provided with four positioning columns 15 distributed in a circular array, and the upper surface of the lower guard plate 1 is provided with four positioning holes 13 distributed one by one with the positioning columns 15. The size of the positioning column 15 matches the size of the positioning hole 13. Through the cooperation between the positioning column 15 and the positioning hole 13, the dividing cone 6 is positioned, which is convenient for its installation and positioning.

[0035] The upper surface of the lower guard plate 1 is located around the dividing cone 6 and is provided with four material guide plates 4 distributed in a circular array. The material guide plate 4 is an L-shaped structure, and the material guide plate 4 is welded and fixed to the upper surface of the lower guard plate 1. The upper surface of the material guide plate 4 is in contact with the bottom of the upper guard plate 2. By setting the material guide plate 4 as an L-shaped structure, it is easier for the material to form a material pad inside the impeller, avoiding the problem of severe impeller wear. The speed of the material at the outer edge of the impeller is relatively large, and it is difficult to form a material lining. Therefore, friction and wear are concentrated on the outer edge of the material guide plate 4, so a wear-resistant carbide throwing head 5 is installed at the end of the material guide plate 4. The end of each guide plate 4 is provided with a throwing head 5 detachably connected thereto, and the throwing head 5 includes a connecting plate 16 and a throwing head base 17 fixedly connected to the connecting plate 16, the top of the throwing head base 17 is fixedly connected to the upper guard plate 2 by bolts, and the side wall of the throwing head base 17 is provided with a card slot 20, and a wear-resistant block 21 is provided in the card slot 20, and the side wall of the connecting plate 16 is provided with three mounting holes distributed at equal intervals up and down, and the side wall of the guide plate 4 is provided with three circular holes distributed one by one corresponding to the mounting holes, and the connecting plate 16 and the guide plate 4 are fixedly connected by bolts. The throwing head 5 is one of the parts with severe wear in the impeller, so the throwing head 5 needs to be replaced frequently during the production process, and the connecting plate 16 and the guide plate 4 are fixedly connected by bolts, so that the throwing head 5 is convenient to remove from the guide plate 4 for replacement, so that the throwing head 5 is easy to disassemble and assemble, and the maintenance cost is reduced at the same time. The slot 20 is an isosceles trapezoidal structure, the size of the wear-resistant block 21 is consistent with the size of the slot 20, and the outer surface of the wear-resistant block 21 is an arc-shaped structure, and the outer surface of the wear-resistant block 21 protrudes from the surface of the throwing head base 17, the wear-resistant block 21 and the slot 20 are fixed by bonding, the top of the throwing head base 17 is provided with an upper positioning block 18, and the bottom is provided with a lower positioning block 19, the bottom of the upper guard plate 2 is provided with four upper positioning grooves 7 in a circumferential array and consistent with the size of the upper positioning block 18, the upper surface of the lower guard plate 1 is provided with four lower positioning grooves 8 distributed in a circumferential array and consistent with the size of the lower positioning block 19, and the upper surface of the upper positioning block 18 is provided with A threaded hole is provided, and a mounting hole connected to the upper positioning groove 7 is provided on the upper surface of the upper guard plate 2. The throwing head 5 is divided into two parts: a throwing head base 17 and a wear-resistant block 21. The throwing head 5 is connected to the upper guard plate 2 and the lower guard plate 1 respectively by the upper positioning block 18 and the lower positioning block 19, and bears the main force. It is connected and fixed to the guide plate 4 through the mounting hole on the connecting plate 16. This installation method transfers part of the tension borne by the bolt to the impeller body, thereby reducing the force on the bolt and preventing the bolt from breaking and failing. Since the degree of wear in various areas of the throwing head 5 is different, the throwing head must be replaced after some areas are severely worn, resulting in material waste and increased production costs.Therefore, a slot 20 is milled out in the easy-to-wear area of ​​the throwing head base 17 to install the wear-resistant block 21. The wear-resistant block 21 is usually bonded to the mounting slot 20 using epoxy resin or brazing technology. The brazing technology has a high bonding strength, and the wear-resistant block 21 is not easy to fall off. However, the cost of the brazing process is high and the processing is complicated. The throwing head 5, as a consumable part, needs to be replaced frequently, so the use of epoxy resin is more economical. In order to prevent the wear-resistant block from falling off due to the failure of the epoxy resin, the structure of the wear-resistant block 21 is improved. The structure of the wear-resistant block 21 and the slot 20 is designed to be wide inside and narrow outside, and the two are bonded and fixed by epoxy resin. Even if the adhesive fails, the wear-resistant block 21 is not easy to fall off, and it is convenient to disassemble and assemble.

[0036] A material channel is formed between the four guide plates 4. The material particle group falls vertically from the feed port 3 to the high-speed rotating material distribution cone 6 by its own gravity. The material distribution cone 6 evenly distributes the material from the feed port 3 into the material channel to avoid the material from being blocked at the feed port 3. After entering the material channel, the material will be accelerated by external forces such as the impact force of the guide plate 4, the centrifugal force of the impeller, and the squeezing force between the materials. The unique structure and installation angle of the guide plate 4 can make the material move along the guide plate 4 toward the outer edge of the impeller at a certain speed. Finally, the material particles reach a certain speed and are thrown out from the end of the material channel, thereby completing the acceleration process.

[0037] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
