Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a quick-change structure for the screen mesh of a vibrating screen for drying sand. Background Technology

[0002] In the production process of dried sand, the vibrating screen is an important piece of equipment for screening the dried sand. As a key component of the vibrating screen, the working condition of the screen directly affects the screening effect. With the increase of usage time, the screen will experience problems such as wear and blockage, and needs to be replaced regularly.

[0003] Currently, existing vibrating screens for drying sand typically use bolts, nuts, and other connectors to fix the screen to the screen frame. This fixing method requires unscrewing each bolt and nut individually when replacing the screen, which is cumbersome and time-consuming. Therefore, we propose a quick-change structure for the screen of a vibrating screen for drying sand to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Unless otherwise specified, the methods used in the present utility model are conventional methods; unless otherwise specified, the raw materials and apparatus used are conventional commercially available products.

[0021] Please see Figure 1-4 In this utility model, the quick-change structure for the screen of the drying sand vibrating screen includes a vibrating screen shell 6 and two support mechanisms 1. The outer surface of the vibrating screen shell 6 is provided with a replacement port 3 and two strip-shaped ports 16. Two concave blocks 10 are fixedly installed on the inner wall of the vibrating screen shell 6. The inner walls of the two concave blocks 10 are slidably connected to the screen body 12. Two limiting plates 9 are fixedly installed on the outer surface of the screen body 12. One end of each limiting plate 9 passes through the strip-shaped port 16 and extends to the outside of the vibrating screen shell 6. The upper surface of each limiting plate 9 is provided with a first limiting hole 18. Two fixing blocks 11 are fixedly installed on the outer surface of the vibrating screen shell 6. The outer surface of each fixing block 11 is provided with a threaded hole 17. The inner wall of each threaded hole 17 is threadedly connected with a limiting pin 13. The top of each limiting pin 13 is fixedly installed with a knob 14. The bottom end of each limiting pin 13 passes through the first limiting hole 18 and extends to the bottom of the limiting plate 9.

[0022] In this embodiment: the two concave blocks 10 together support the screen body 12. By connecting the outer surfaces of the two limiting pins 13 to the inner walls of the two threaded holes 17 respectively, and installing a knob 14 at the top of each limiting pin 13, the operator can change the position of the two limiting pins 13 by rotating the two knobs 14. When the bottom ends of the two limiting pins 13 are moved out of the first limiting hole 18, the limiting effect on the screen body 12 can be released.

[0023] As a technical optimization of this utility model, a baffle 5 is fixedly installed on the outer surface of the screen body 12, the outer surface of the baffle 5 is in contact with the inner wall of the replacement port 3, and a handle 4 is fixedly installed on the surface of the baffle 5.

[0024] In this embodiment: by installing a baffle 5 on the outer surface of the screen body 12 and making the outer surface of the baffle 5 contact the inner wall of the replacement port 3, the leakage of dried sand from the replacement port 3 during the screening process can be effectively prevented. By installing a handle 4 on the outer surface of the baffle 5, the operator can quickly pull the screen body 12 out of the vibrating screen housing 6 using the handle 4.

[0025] As a technical optimization of this utility model, four connecting blocks 2 are fixedly installed on the outer surface of the vibrating screen shell 6. A set of springs 8 are fixedly installed on the bottom surface of each connecting block 2. The bottom end of each set of springs 8 is fixedly installed on the upper surface of the support mechanism 1. Two sets of limiting rods 7 are fixedly installed on the upper surface of each support mechanism 1. A second limiting hole 15 is opened on the upper surface of each connecting block 2. The top end of each limiting rod 7 passes through the second limiting hole 15 and extends to the top of the connecting block 2.

[0026] In this embodiment: by installing four connecting blocks 2 on the outer surface of the vibrating screen housing 6 and assembling the four connecting blocks 2 with two support mechanisms 1 using four sets of springs 8, the resonance amplitude of the two support mechanisms 1 can be effectively improved when using the device to screen dried sand. The two support mechanisms 1 together support the vibrating screen housing 6. By installing two sets of limiting rods 7 on the upper surface of each support mechanism 1 and making the top of each limiting rod 7 pass through the second limiting hole 15 and extend to the top of the connecting block 2, the vibrating screen housing 6 can be effectively prevented from shaking left and right or back and forth during the screening process.

[0027] As a technical optimization of this utility model, each support mechanism 1 includes two load-bearing plates 102, a support plate 103 is fixedly installed on the bottom surface of each load-bearing plate 102, a base 104 is fixedly installed on the bottom surface of each support plate 103, and a connecting rod 101 is fixedly installed on the side of each set of support plates 103 that are close to each other.

[0028] In this embodiment: each connecting rod 101 serves to connect and reinforce the two support plates 103. The connecting rod 101 can effectively enhance the stability of the support mechanism 1. By installing a base 104 on the bottom surface of each support plate 103, the contact area between the device and the ground can be effectively increased. According to actual usage requirements, mounting holes can be opened on the upper surface of the base 104. When the operator uses bolts to pass through the mounting holes opened on the upper surface of the base 104, the device can be firmly installed on the ground.

[0029] The working principle of this utility model is as follows: When it is necessary to remove the screen body 12, the operator first rotates the two knobs 14 in sequence. Each knob 14 rotation drives the limit pin 13 to rotate. Through the cooperation of the two limit pins 13 with the two threaded holes 17, each limit pin 13 can gradually move upward during the rotation. When the bottom ends of the two limit pins 13 have moved out of the first limit hole 18, the operator can pull the screen body 12 out of the vibrating screen shell 6 through the pull handle 4.

[0030] However, the above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
