Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel crushing and feeding technology, specifically a feeding device for a sand and gravel crushing vibrating screen. Background Technology
[0002] After sand and gravel are crushed, they will produce sand and gravel particles of different sizes. Vibrating screens, as a type of efficient screening equipment, separate materials of different sizes by vibrating on a screen mesh. During screening, sand and gravel particles of different sizes are conveyed into the vibrating screen through a feeding device. However, there is a problem: because water is generally used for cooling during sand and gravel crushing, the crushed sand and gravel has an excessively high moisture content. This causes the sand and gravel particles with high moisture content to easily stick together. These sticky sand and gravel particles are prone to forming lumps or clusters during the feeding process, making screening more difficult.
[0003] Therefore, we propose a feeding device for a vibrating screen for crushing sand and gravel. Utility Model Content

[0016] 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 protection scope of the present utility model.
[0017] Example
[0018] Please see Figures 1-2The diagram shows a feeding device for a sand and gravel crushing vibrating screen, comprising a conveyor belt 1 and a frame 2. The conveyor belt 1 is located inside the frame 2, and a base 3 is located above the conveyor belt 1. A first drain pipe 4 is located on one side of the base 3, and a second drain pipe 5 is located on the other side of the first drain pipe 4. A water inlet pipe 6 is located above the second drain pipe 5. A filter plate 7 is located inside the base 3. The filter plate 7 is rotatably connected to an impeller 8. One end of the impeller 8 is fixedly connected to an output gear 9. The output gear 9 is meshed with a chain 10. The chain 10 is meshed with an input gear 11. The input gear 11 is fixedly connected to a motor 12. A guide plate 13 is located on one side of the filter plate 7, and a fan 14 is located above the guide plate 13. The fan accelerates the evaporation of moisture from the surface of the sand and gravel particles, thereby improving the dewatering efficiency of the sand and gravel particles and solving the problem of lumps or clumps formed due to high moisture content.
[0019] Furthermore, the base 3 has a filter chamber, and a drain chamber is provided on one side of the filter chamber. The drain chamber is fixedly connected to the drain pipe 4. The base is carefully divided into filter chambers. The filter chamber area is specifically used to contain and process sand and gravel particles with high water content. The drain chamber is provided on one side of the filter chamber. The drain chamber is designed to efficiently collect and discharge the water separated during the filtration process. The drain chamber guides the water smoothly out of the system through the fixedly connected drain pipe 4, ensuring the continuity and stability of the dehydration process.
[0020] Furthermore, the drain chamber is fixedly connected to the guide plate 13, and a guide plate 15 is provided below the guide plate 13. The drain chamber serves as a key component for water collection and discharge. The fixed connection between the drain chamber and the guide plate ensures that the water separated during the dehydration process can be smoothly and orderly guided into the drain pipe. A guide plate is installed below the guide plate. The shape and angle of the guide plate are carefully designed to further guide and accelerate the flow of water, ensuring that the water can be quickly and completely discharged from the system.
[0021] Furthermore, the filter chamber is equipped with a filter plate 7, which has perforations. The size of these perforations ensures that sand and gravel particles are effectively processed during dewatering while preventing particle loss. This allows for effective cleaning of sand and gravel particles of different sizes. Smaller perforations prevent fine particles from passing through, ensuring that the quality of the dewatered sand and gravel particles meets requirements. Simultaneously, the perforation design also considers the rolling and friction of sand and gravel particles, which helps to further break down and disperse adhering particles.
[0022] Furthermore, the fans 14 are arranged in a row and are fixedly connected to the top of the base 3. As an important component to assist in dehydration, the design of the fans in a row ensures that the airflow can be evenly and widely covered on the sand and gravel particles. Each fan is precisely installed on the top of the base, and the fixed connection ensures the stability and reliability of the fans during the dehydration process.
[0023] Furthermore, the motor 12 is fixedly connected to the top of the base 3, and the output shaft of the motor 12 is fixedly connected to the input gear 11. By fixing the motor to the top of the base, not only is the motor's stability ensured during operation and displacement caused by vibration or external force avoided, but the fixed connection between the motor's output shaft and the input gear also enables power transmission. The fixed connection ensures that the rotational power generated by the motor can be efficiently and without loss transmitted to the input gear, thereby driving the impeller to ensure the guidance of sand and gravel.
[0024] In this solution, the workflow is as follows: First, the freshly crushed sand and gravel raw material is directly fed into the filter chamber inside the base 3.
[0025] The filter plate 7 inside the filter chamber has holes that allow water to pass through while retaining sand and gravel particles. At the same time, the filter plate 7 is rotatably connected to the impeller 8. When the impeller rotates, it further promotes the tumbling and dispersion of sand and gravel particles, accelerating the dewatering process.
[0026] The water separated during the dehydration process passes through the drain chamber on one side of the filter chamber and is smoothly discharged from the system via drain pipe 4 and drain pipe 5. The drain chamber is also fixedly connected to a guide plate 13, and a flow guide plate 15 is provided below the guide plate, which together ensures the rapid and orderly discharge of water.
[0027] The motor 12 is fixedly connected to the top of the base 3, and its output shaft is tightly connected to the input gear 11. When the motor starts, its rotational power is transmitted to the input gear through the output shaft.
[0028] The input gear 11 meshes with the chain 10, which in turn meshes with the output gear 9. In this way, the power of the motor is transmitted to the impeller 8 through the gear and chain, driving it to rotate.
[0029] At the top of the base 3, fans 14 are arranged in a row and fixedly connected. When the device is running, the fans start simultaneously, generating strong airflow that acts on the sand and gravel particles on the filter plate 7, further accelerating the evaporation of moisture from its surface and improving dehydration efficiency.
[0030] After the above dehydration and screening process, most of the moisture in the sand and gravel raw materials is removed, and the sand and gravel particles that meet the requirements are left on the filter plate 7 and fall onto the conveyor belt, and are then transported to the subsequent vibrating screen for further screening and processing to meet different production needs.
