Description
Technical Field
[0001] This utility model relates to the field of sand screening technology, and in particular to a sand screening device that facilitates material feeding. Background Technology
[0002] A sand screening device is a mechanical device used for separating and screening sand, widely used in construction, engineering, mining, and other fields. Its main function is to separate sand of different particle sizes using the principle of screening to meet various engineering needs. A sand screening device typically includes components such as a screen, a vibrating mechanism, and a transmission system, enabling efficient screening of sand. Sand screening devices usually require the material to be transported from a high position or over a long distance to the inside of the equipment.
[0003] In existing technologies, traditional feeding devices are mostly fixed structures, unable to be flexibly adjusted according to the installation height and feed inlet position of the sand screening machine. When changing to different models of sand screening machines or adjusting the work site, the feeding equipment is often difficult to adapt, requiring reinstallation and debugging, resulting in extremely poor adaptability. Moreover, most feeding machines only have a simple conveying function; after being conveyed, the material directly flows into the sand screening machine without an effective dispersing mechanism, causing the material to accumulate in clumps on the screen, unable to spread quickly and evenly. This results in some areas of the screen surface having no material to screen, while other areas have excessively thick material, which not only reduces screening efficiency and accuracy but also increases the risk of equipment failure due to excessive local impact force of the material on the screen. Therefore, we propose a sand screening device that facilitates feeding to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sand screening device that facilitates material feeding.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sand screening device for easy feeding includes a feeding hopper and a sand screening machine. An inclined U-shaped frame is fixedly connected to the outer wall of the feeding hopper. A belt conveyor is fixedly connected inside the inclined U-shaped frame. A support frame is fixedly connected to the outer wall of the inclined U-shaped frame. Four legs are fixedly connected to the outer wall of the feeding hopper. An arc-shaped guide frame is fixedly connected to one end of the inclined U-shaped frame. A discharge hopper is fixedly connected to the bottom of the arc-shaped guide frame. A discharge pipe is fixedly connected to the bottom of the discharge hopper. A T-shaped telescopic pipe is sleeved on the outer wall of the discharge pipe. A support plate is fixedly connected between the discharge hopper and the inclined U-shaped frame. An electric push rod is fixedly connected to the bottom of the support plate. The bottom of the output end of the electric push rod is fixedly connected to the outer wall of the T-shaped telescopic pipe. A dispersion component is provided at the bottom of the T-shaped telescopic pipe.
[0007] Preferably, the dispersing component includes a dispersing disc, two pillars are fixedly connected to the bottom of the T-shaped telescopic tube, the bottom of the two pillars are fixedly connected to the same chassis, a servo motor is fixedly connected to the bottom of the chassis, a conical disc is fixedly connected to the top of the chassis, and the top of the output shaft of the servo motor is fixedly connected to the bottom of the dispersing disc. By setting the dispersing component, the dispersing disc is driven to rotate, and the material is dispersed by centrifugal force.
[0008] Preferably, multiple V-shaped conveyor plates are uniformly fixedly installed on the outer wall of the belt conveyor. The V-shaped conveyor plates are made of rubber and are fixed to the outer wall of the conveyor belt inside the belt conveyor.
[0009] Preferably, the bottom of the support frame and the four legs are all fixedly connected to casters, the casters are equipped with foot brakes, and the foot brakes transmit torque through levers or mechanical connections.

[0011] Preferably, both the dispersing disc and the conical disc are located at the top of the sand screening machine.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] This solution allows for easy adjustment of the equipment position via casters, and the T-shaped telescopic tube is moved by an electric push rod, adapting to the installation height and feed inlet position of different sand screening machines without the need for reinstallation and debugging, significantly improving adaptability.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1-5 As shown, a sand screening device for easy feeding is disclosed, including a feeding hopper 1 and a sand screening machine 16 (2YK2460). An inclined U-shaped frame 2 is fixedly connected to the outer wall of the feeding hopper 1. A belt conveyor 3 is fixedly connected inside the inclined U-shaped frame 2. Multiple V-shaped conveyor plates 18 are evenly fixedly installed on the outer wall of the belt conveyor 3. The U-shaped structure of the inclined U-shaped frame 2 can provide lateral protection for the conveyor belt and the V-shaped conveyor plates 18, preventing materials from slipping off from both sides during the conveying process.
[0023] A support frame 4 is fixedly connected to the outer wall of the inclined U-shaped frame 2. The support frame 4 supports the suspended end of the inclined U-shaped frame 2. Four legs 5 are fixedly connected to the outer wall of the feeding bin 1. Casters 17 are fixedly connected to the bottom of the support frame 4 and the four legs 5. An arc-shaped guide frame 7 is fixedly connected to one end of the inclined U-shaped frame 2. A feeding bin 6 is fixedly connected to the bottom of the arc-shaped guide frame 7. The arc-shaped structure of the arc-shaped guide frame 7 conforms to the trajectory of the material falling from the end of the conveyor belt, which can effectively guide the material to slide smoothly into the feeding bin 6. A feeding pipe 8 is fixedly connected to the bottom of the feeding bin 6. The feeding bin 6 receives the material from the arc-shaped guide frame 7. Its funnel-shaped structure can collect the material and ensure that the material flows into the feeding pipe 8.
[0024] The outer wall of the feeding pipe 8 is fitted with a T-shaped telescopic pipe 9. A support plate is fixedly connected between the feeding bin 6 and the inclined U-shaped frame 2. An electric push rod 10 is fixedly connected to the bottom of the support plate. The bottom of the output end of the electric push rod 10 is fixedly connected to the outer wall of the T-shaped telescopic pipe 9. Driven by the electric push rod 10, the push rod 10 moves up and down along the feeding pipe 8 to adjust the height of the dispersing component and adapt to different feeding height requirements.
[0025] The bottom of the T-shaped telescopic pipe 9 is equipped with a dispersion component, which includes a dispersion disc 15. Two support columns 11 are fixedly connected to the bottom of the T-shaped telescopic pipe 9. The bottom of the two support columns 11 is fixedly connected to the same base plate 12. The support columns 11 connect the T-shaped telescopic pipe 9 and the base plate 12, and play the role of supporting and raising the base plate 12, so that a reasonable space is formed between the base plate 12 and the T-shaped telescopic pipe 9. This avoids structural interference between the dispersion component and the T-shaped telescopic pipe 9, and ensures that the material can fall smoothly from the T-shaped telescopic pipe 9 into the dispersion disc 15.
[0026] A servo motor 13 is fixedly connected to the bottom of the chassis 12, and a conical disk 14 is fixedly connected to the top of the chassis 12. The top of the output shaft of the servo motor 13 is fixedly connected to the bottom of the dispersing disk 15. The outer walls of both the chassis 12 and the conical disk 14 are provided with through holes, and the inner walls of the through holes are rotatably connected to the outer walls of the output shaft of the servo motor 13. The dispersing disk 15 and the conical disk 14 are both located on the top of the sand screening machine 16 (2YK2460). Driven by the servo motor 13, they rotate and further throw the material initially dispersed by the conical disk 14 onto the screen of the sand screening machine 16 (2YK2460) through centrifugal force. The rotation speed can be adjusted according to the width of the sand screening machine 16 (2YK2460) to control the dispersion range, ensure that the material evenly covers the screen, improve the screen utilization rate and screening efficiency, and reduce the local impact of the material on the screen.
[0027] Working principle: During operation, multiple casters 17 move the feeding hopper 1 and the inclined U-shaped frame 2 to position the discharge pipe 8 at the top of the sand screening machine 16. The electric push rod 10 drives the T-shaped telescopic pipe 9 downwards. The T-shaped telescopic pipe 9 moves downwards along the discharge pipe 8, and also drives the chassis 12 and servo motor 13 downwards, so that the servo motor 13 is slightly higher than the top of the sand screening machine 16. The dispersing disc 15 is located at the top of the middle position of the screen inside the sand screening machine 16. Material is added to the feeding hopper 1, and the material is then conveyed by the belt conveyor 3. The rotating conveyor belt drives multiple V-shaped conveyor plates 18 connected to it to rotate. The rotation of the multiple V-shaped conveyor plates 18 drives the material upward and then into the feeding hopper 6. The material enters the feeding pipe 8 from the feeding hopper 6, and then enters the T-shaped telescopic pipe 9 from the feeding pipe 8, falling onto the top of the dispersing disc 15. The setting of the dispersing disc 15 and the conical disc 14 can disperse the material onto the screen. The servo motor 13 drives the dispersing disc 15 to rotate, expanding the dispersion range through centrifugal force. The width can be selected according to the width of the sand screening machine 16.
[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the belt conveyor 3, electric push rod 10, servo motor 13, and sand screening machine 16 to facilitate the control of the overall operation.
