Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel processing, specifically relating to a conveying device for sand and gravel desliming and dewatering equipment. Background Technology

[0002] In many industries such as construction, mining, and chemical industry, the transportation of sand and gravel is an important part of the production process. At present, ordinary sand and gravel transportation devices usually use conveyor belts as the transportation carrier. The working principle is to place the sand and gravel to be transported directly on the conveyor belt, and rely on the movement of the conveyor belt to realize the transportation of sand and gravel.

[0003] However, this traditional method of sand and gravel transportation has certain drawbacks. When sand and gravel are placed directly on the conveyor belt, the lack of effective buffering and flow equalization measures can cause impacts on the conveyor belt, potentially damaging its surface and reducing its service life. The distribution of sand and gravel on the conveyor belt is often uneven, leading to inconsistent load-bearing conditions in different parts of the belt. Excessive pressure in certain areas can damage the conveyor belt over time, shortening its lifespan. Furthermore, uneven pressure during transportation can cause different frictional forces on both sides of the conveyor belt, potentially leading to belt misalignment. This misalignment not only affects the normal transport of sand and gravel but also exacerbates wear between the conveyor belt and other equipment components, further increasing maintenance costs and downtime, and negatively impacting production efficiency. Utility Model Content

[0004] To overcome the problem that directly dumping sand and gravel during use may damage the conveyor belt, a new type of sand and gravel desliming and dewatering equipment conveyor device is proposed.

[0005] The technical solution of this utility model is as follows: a conveying device for sand and gravel desliming and dewatering equipment, including a conveying mechanism and a buffering mechanism. The conveying mechanism includes a conveying seat and a conveyor belt. A buffering mechanism and a tensioning mechanism are installed on the conveying mechanism. A bearing mechanism is installed below the conveying mechanism. Symmetrical conveying rollers are rotatably installed on the inner edges of the front and rear ends of the conveying seat. A conveyor belt is installed on the outer wall of the conveying rollers. The outer wall of the conveying rollers is tapered. The outer diameter of the two ends of the conveying rollers is larger than the outer diameter of the middle part. The buffering mechanism includes a support frame. A feed cylinder is installed on the inner wall of the support frame. The lower opening of the feed cylinder corresponds to the upper outer wall of the conveyor belt. Symmetrically distributed guide plates are fixed to the inner wall of the feed cylinder. A grid is fixed to the lower opening of the feed cylinder. The tensioning mechanism includes an electric cylinder. The electric cylinder is fixed to the lower inner wall of the conveying seat. A movable frame is fixed to the output end of the electric cylinder. Tensioning rollers are rotatably installed on the inner walls of the front and rear ends of the movable frame. The outer wall of the tensioning rollers is in contact with the lower inner wall of the conveyor belt.

[0006] Furthermore, support rollers are rotatably installed on the inner walls of the front and rear ends of the conveyor seat. The support rollers are located between the conveyor rollers, and the outer wall of the support rollers is in contact with the upper inner wall of the conveyor belt.

[0007] Furthermore, a servo motor and an electric motor are fixedly connected to the outer wall of the conveyor seat. The output end of the servo motor is connected to the rotating shaft of the left conveyor roller. Brush rollers are rotatably installed on the inner walls of the front and rear ends of the conveyor seat.

[0008] Furthermore, the output end of the motor is connected to the shaft of the brush roller, the brush roller is located on the lower side of the conveyor belt, and the outer wall of the brush roller is in contact with the lower outer wall of the conveyor belt.

[0009] Furthermore, several support bars are fixed to the outer wall of the conveyor belt, encircling the conveyor belt. Symmetrical baffles are fixed to the upper edge of the conveyor seat, with the lower end of the baffles fitting against the upper end of the conveyor belt.

[0010] Furthermore, a sliding groove is provided at the inner edge of the front and rear ends of the conveyor seat, and a slider is slidably installed in the sliding groove. The slider is fixed to the outer wall of the front and rear ends of the movable frame, and the extension direction of the sliding groove is the same as the extension and retraction direction of the output end of the electric cylinder.

[0011] Furthermore, the supporting mechanism includes a base, with a conveyor seat rotatably mounted on the inner walls of the front and rear ends of the base, and symmetrical hydraulic cylinders fixed to the upper edge of the base. The output ends of the hydraulic cylinders are all fixed to a support frame, which is rotatably mounted on the outer wall of the conveyor seat.

[0012] The beneficial effects of this utility model are as follows: The conveyor belt can be supported by the conveyor rollers. The outer diameter of the front and rear ends of the conveyor rollers is larger than the outer diameter of the center, which allows the conveyor belt to be automatically centered. In conjunction with the output end of the electric cylinder, the movable frame moves up and down, and the tension rollers are adjusted to fit and press the conveyor belt, which can reduce the probability of the conveyor belt shifting forward and backward. The feed cylinder can guide the sand and gravel entering the conveyor belt. The guide plate can evenly guide the sand and gravel into the upper end of the grid. The grid can buffer the sand and gravel and make the sand and gravel fall evenly on the conveyor belt, reducing the impact of sand and gravel on the conveyor belt. Compared with the existing sand and gravel conveying device, the added buffer mechanism can buffer the falling sand and gravel and make the sand and gravel fall evenly on the conveyor belt, reducing the damage to the conveyor belt. The added conveyor rollers and tensioning mechanism can keep the conveyor belt taut and automatically center the conveyor belt, reducing the probability of the conveyor belt shifting under load.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-7This utility model provides an embodiment of a sand and gravel desliming and dewatering equipment conveying device, including a conveying mechanism 1 and a buffering mechanism 2. The conveying mechanism 1 includes a conveying seat 101 and a conveyor belt 105. The buffering mechanism 2 and a tensioning mechanism 3 are installed on the conveying mechanism 1, and a bearing mechanism 4 is installed below the conveying mechanism 1. Symmetrical conveying rollers 102 are rotatably installed on the inner edges of the front and rear ends of the conveying seat 101. The conveyor belt 105 is installed on the outer wall of the conveying rollers 102. The outer wall of the conveying rollers 102 has a taper, and the outer diameter at both ends of the conveying rollers 102 is larger than the outer diameter at the middle. The buffering mechanism 2 includes a support frame 20. 1. A feed cylinder 202 is installed on the inner wall of the support frame 201. The lower opening of the feed cylinder 202 corresponds to the upper outer wall of the conveyor belt 105. Symmetrically distributed guide plates 203 are fixed to the inner wall of the feed cylinder 202. A grid 204 is fixed to the lower opening of the feed cylinder 202. The tensioning mechanism 3 includes an electric cylinder 301. The electric cylinder 301 is fixed to the lower inner wall of the conveyor seat 101. A movable frame 302 is fixed to the output end of the electric cylinder 301. Tensioning rollers 303 are rotatably installed on the inner walls of the front and rear ends of the movable frame 302. The outer wall of the tensioning rollers 303 is in contact with the lower inner wall of the conveyor belt 105.

[0023] The conveyor belt 105 is supported by the conveyor roller 102. The outer diameter of the front and rear ends of the conveyor roller 102 is larger than the outer diameter of the center, which allows the conveyor belt 105 to be automatically centered. In conjunction with the output end of the electric cylinder 301, the movable frame 302 is moved up and down. The tension roller 303 is adjusted to fit and press the conveyor belt 105, which can reduce the probability of the conveyor belt 105 shifting back and forth. The feed cylinder 202 can guide the sand and gravel entering the conveyor belt 105. The guide plate 203 can evenly guide the sand and gravel into the upper end of the grid 204. The grid 204 can buffer the sand and gravel and make the sand and gravel fall evenly on the conveyor belt 105, reducing the impact of the sand and gravel on the conveyor belt 105 and making the pressure on the conveyor belt 105 uniform.

[0024] Please see Figure 3 In this embodiment, support rollers 104 are rotatably mounted on the inner walls of the front and rear ends of the conveyor seat 101. The support rollers 104 are located between the conveyor rollers 102. The outer wall of the support rollers 104 is in contact with the upper inner wall of the conveyor belt 105. In use, the support rollers 104 can support the upper inner wall of the conveyor belt 105 to ensure the stability of the conveyor belt 105 during operation. A servo motor 103 and an electric motor 107 are fixedly connected to the outer wall of the conveyor seat 101. The output end of the servo motor 103 is connected to the rotating shaft of the left conveyor roller 102. Brush rollers 106 are rotatably mounted on the inner walls of the front and rear ends of the conveyor seat 101. In use, the output end of the servo motor 103 can drive the conveyor rollers 102 to rotate, thereby driving the conveyor belt 105 to rotate and transport sand and gravel.

[0025] Please see Figures 3-4In this embodiment, the output end of the motor 107 is connected to the rotating shaft of the brush roller 106. The brush roller 106 is located on the lower side of the conveyor belt 105, and the outer wall of the brush roller 106 is attached to the lower outer wall of the conveyor belt 105. During use, the output end of the motor 107 can drive the brush roller 106 to rotate, which can clean the lower end of the conveyor belt 105 and prevent the accumulation of mud and dust from affecting the work. Several support bars 110 are fixed to the outer wall of the conveyor belt 105 and surround the conveyor belt 105. A front and rear symmetrical baffle 108 is fixed to the upper edge of the conveyor seat 101. The lower end of the baffle 108 is attached to the upper end of the conveyor belt 105. During use, the support bars 110 can increase the surface friction of the conveyor belt 105, thereby improving the stability of conveying sand and gravel. The baffle 108 can separate the front and rear ends of the conveyor belt 105 to prevent sand and gravel from falling off the conveyor belt 105.

[0026] Please see Figures 4-5 In this embodiment, grooves 109 are provided at the inner edges of the front and rear ends of the conveyor seat 101. A slider 304 is slidably disposed in the grooves 109. The slider 304 is fixed to the outer walls of the front and rear ends of the movable frame 302. The extension direction of the grooves 109 is the same as the extension and retraction direction of the output end of the electric cylinder 301. In use, the grooves 109 and the slider 304 can improve the stability of the up and down movement of the movable frame 302, thereby ensuring the stability of the tension of the conveyor belt 105. The bearing mechanism 4 includes a base 401. The conveyor seat 101 is rotatably mounted on the inner walls of the front and rear ends of the base 401. The upper edge of the base 401 is fixedly connected to the symmetrical hydraulic cylinders 402. The output ends of the hydraulic cylinders 402 are fixedly connected to the support frame 403. The support frame 403 is rotatably mounted on the outer wall of the conveyor seat 101. In use, the base 401 can support the conveyor seat 101. The output ends of the hydraulic cylinders 402 can drive the support frame 403 to move up and down, and the tilt angle of the conveyor seat 101 can be adjusted to adapt to different conveying environments.

[0027] During operation, firstly, the hydraulic cylinder 402 is started, and the angle of the conveyor seat 101 is adjusted according to the conveying requirements. Then, the servo motor 103 is started, so that the output end of the servo motor 103 drives the conveyor roller 102 to rotate, which in turn drives the conveyor belt 105 to rotate. Then, the electric cylinder 301 is started, and the output end of the electric cylinder 301 is adjusted according to the rotation of the conveyor belt 105 to keep the conveyor belt 105 taut. Next, the motor 107 is started, so that the output end of the motor 107 drives the brush roller 106 to rotate, preventing a large amount of mud and dirt from sticking to the surface of the conveyor belt 105. Then, the sand and gravel to be conveyed are poured into the feed cylinder 202, so that the sand and gravel fall into the upper end of the conveyor belt 105 after passing through the guide plate 203 and the grid 204. Wait for the conveyor belt 105 to send the sand and gravel to the next process. Finally, the feed cylinder 202 is pulled upward, removed, and cleaned.

[0028] Through the above steps, the conveyor roller 102 can support the conveyor belt 105. The outer diameter of the front and rear ends of the conveyor roller 102 is larger than the outer diameter of the center, which can make the conveyor belt 105 automatically center. In conjunction with the output end of the electric cylinder 301, the movable frame 302 moves up and down. Adjusting the tension roller 303 to fit and press the conveyor belt 105 can reduce the probability of the conveyor belt 105 shifting back and forth. The feed cylinder 202 can guide the sand and gravel entering the conveyor belt 105. The guide plate 203 can evenly guide the sand and gravel into the upper end of the grid 204. The grid 204 can buffer the sand and gravel and make the sand and gravel fall evenly on the conveyor belt 105. This solves the problem that directly dumping sand and gravel may damage the conveying surface when the sand and gravel conveying device is in use.
