Through the optimization of process flow, it has excellent rock crushing, aggregate production, and open-pit mining crushing performance. Through the combination of different models, it can form a powerful crushing operation line to complete multi-demand processing operations. When the crushing equipment is working, the material enters the crushing host through the feed bin for crushing operation, and the crushed material enters the material screening system through the conveying device for screening. The materials that meet the requirements of the finished product are sent to the designated location through the finished product conveyor belt, while the materials that do not meet the requirements of the finished product (that is, the larger materials that have not been completely crushed) are returned to the feed bin through the return belt for secondary crushing.
[0003] In the prior art, due to the structure and spatial layout of the crushing equipment, the return belt and the feed bin are generally connected by a fixed connection receiving hopper to allow the material to fall from the return belt into the feed bin. After the receiving hopper is fixedly connected to the return belt, the tension of the return belt needs to be adjusted, which will cause the position of the return belt to change, that is, the gap between the receiving hopper and the return belt will be too large, and finally leakage will occur. In addition, the receiving hopper is fixedly connected to the return belt, and the receiving hopper is always in a higher position, which will cause the problem of restricted transportation. Therefore, based on the current status of the return process of the crushing equipment, there is an urgent need for a device to solve the problems of leakage and restricted transportation during the return process.

Implementation
[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0017] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.
[0018] Combine the following Figure 1-3 The specific implementation mode of the utility model is described.
[0019] The present embodiment provides a material return system for a crushing device, the material return system comprises a receiving hopper 1, a material return belt 2, a feeding bin 3, and a material return belt support frame 4, wherein the material return belt support frame 4 is arranged at the lower side of the material return belt 2. The material receiving hopper 1 comprises a material receiving hopper body 5, a connecting frame 6, a wear-resistant plate 7, and a scraper plate 8, and the material receiving hopper body 5 has a material receiving cavity 9, a material receiving hopper inlet 10, and a material receiving hopper outlet 11.
[0020] The receiving hopper 1 is arranged between the return belt 2 and the feed bin 3. Specifically, the discharge port of the return belt 2 is adjacent to the receiving hopper inlet 10, and the feed port of the feed bin 3 is adjacent to the receiving hopper outlet 11. Furthermore, a receiving plate 14 is arranged between the feed port of the feed bin 3 and the receiving hopper outlet 11. Since the return belt 2 and the receiving hopper 1 are located on the side of the feed bin 3, there is a certain distance between the receiving hopper outlet 11 and the feed bin 3, such as Figure 2 shown.
[0021] When the material is discharged through the receiving hopper outlet 11, most of the material will fall into the feed bin 3, but some of the material cannot accurately fall into the feed bin 3 and cause leakage. Therefore, a receiving plate 14 is fixedly arranged at the feed port of the feed bin 3. The receiving plate 14 effectively extends the height and width of the feed port of the feed bin 3, ensuring that when the material is discharged through the receiving hopper outlet 11, all of the material accurately falls into the feed bin 3 for secondary crushing, effectively solving the leakage problem of the return system. Preferably, the receiving plate 14 is connected to the feed port of the feed bin 3 by bolts, so as to facilitate the quick disassembly and assembly of the receiving plate 14.
[0022] The wear-resistant plate 7 is arranged on the inner wall of the receiving cavity 9, which can transfer the wear of the material docking hopper body 5 to the wear of the vulnerable part wear-resistant plate 7, effectively improving the wear resistance of the receiving hopper body 5 and extending the service life. Preferably, a plurality of wear-resistant plates 7 are connected by bolts at various positions of the inner wall of the receiving cavity 9 to improve the disassembly and assembly efficiency of the wear-resistant plates 7.
[0023] The connecting frame 6 is provided with a plurality of long holes 12, and corresponding mounting circular holes are respectively provided on both sides of the discharge port of the return belt 2. The connecting frame 6 is fixed to the return belt 2 by bolts to realize the connection between the receiving hopper 1 and the return belt 2. The corresponding positions of the long holes 12 and the mounting circular holes can be adjusted according to the needs of the site, so as to adjust the distance between the receiving hopper 1 and the return belt 2 to a distance that meets the needs of different sites, effectively solving the leakage problem of the return system.
[0024] The return belt 2 has a discharge roller 13, and a scraper plate 8 is arranged at the lower side of the discharge roller 13 and fixedly connected to the receiving hopper body 5. When the material of the return belt 2 is discharged along with the discharge roller 13, most of the material will fall into the receiving hopper 1 in a parabolic shape, but a part of the material will adhere to the surface of the discharge roller 13. Therefore, a scraper plate 8 is arranged at the lower side of the discharge roller 13. When the material adhered to the discharge roller 13 rotates to the scraper plate 8 along with the rotation of the discharge roller 13, the scraper plate 8 will scrape this part of the material from the surface of the discharge roller 13, and finally it can still fall into the receiving hopper 1, which effectively solves the leakage problem of the return system and the blockage problem of the discharge roller.
[0025] The return belt support frame 4 includes a telescopic hydraulic cylinder 15, wherein one end of the return belt support frame 4 is fixedly connected to the return belt 2, and the other end of the return belt support frame 4 is fixedly connected to the main frame of the crushing equipment. When the crushing equipment is in the process of transportation, the piston of the telescopic hydraulic cylinder 15 retracts, which drives the return belt 2 to rotate downward to lower the height of the crushing equipment to meet the transportation requirements. When the crushing equipment is working, the piston of the telescopic hydraulic cylinder 15 extends, which drives the return belt 2 to rotate upward, and the return belt 2 drives the receiving hopper 1 to rise to the feeding port of the feed bin 3 to ensure that the material of the return belt 2 falls into the feed bin 3.
[0026] The working principle of the utility model is:
[0027] When the crushing equipment needs to be transported, the receiving plate 14 and / or the receiving hopper 1 are removed, and then the piston of the telescopic hydraulic cylinder 15 is controlled to retract so that the return belt 2 rotates downward to reduce the height of the crushing equipment to meet the transportation requirements of the crushing equipment.
[0028] When the crushing equipment arrives at the work site, the piston of the telescopic hydraulic cylinder 15 is controlled to extend so that the return belt 2 rotates upward to a suitable height, and then the receiving plate 14 and / or the receiving hopper 1 are installed. When the crushing equipment is working, the material in the return belt 2 is continuously moved to the receiving hopper 1 by the drive of the discharge roller 13, and most of the material falls into the receiving hopper 1 in a parabolic shape, while the other part of the material adheres to the surface of the discharge roller 13 and moves to the scraper plate 8 as the discharge roller 13 rotates. At this time, the scraper plate 8 will scrape this part of the material from the surface of the discharge roller 13, and finally this part of the material can still fall into the receiving hopper 1, effectively solving the problem of material leakage in the return system and the problem of material blocking in the discharge roller.
[0029] When the material is discharged through the receiving hopper outlet 11 of the receiving hopper 1, the receiving plate 14 has the function of extending the height and width of the feed port of the feed bin 3, ensuring that when the material is discharged through the receiving hopper outlet 11, all of it falls accurately into the feed bin 3 for secondary crushing, effectively solving the leakage problem of the return system.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
