Description

Technical Field

[0001] This utility model relates to the field of sand and gravel washing equipment, specifically to a wheel bucket type sand washing device. Background Technology

[0002] Concrete, a key material widely used in civil engineering, shipbuilding, machinery manufacturing, marine development, and geothermal engineering, plays a decisive role in the quality of engineering projects due to its strength. During concrete preparation, sand and gravel, as important aggregates, are susceptible to damage from impurities such as dust and mud on their surfaces, which can severely affect the strength and durability of the concrete. Therefore, cleaning the sand and gravel using sand and gravel cleaning equipment before concrete preparation is an essential and crucial step.

[0003] Currently, the wheel bucket sand washing machine is a common sand and gravel cleaning equipment. It mainly consists of a wheel bucket, a sand washing tank, and a transmission device. During sand washing, the wheel bucket sand washing machine relies on the rotation of the wheel bucket to drive the sand and gravel to continuously roll and grind against each other inside the sand washing tank. With the help of the impact of the water flow, the dust, mud, and other impurities on the surface of the sand and gravel are cleaned. At the same time, the sand washing bucket set in the wheel bucket will scoop up the sand and gravel in the sand washing tank, dehydrate it, and throw it out.

[0004] In the existing technology, during the sand washing process, smaller sand particles remain in the washing bucket of the wheel bucket sand washing machine, occupying the space inside the washing bucket and reducing the amount of sand scooped up by the washing bucket during the sand washing process, resulting in a decrease in the sand washing efficiency of the wheel bucket sand washing machine. Utility Model Content

[0005] The purpose of this utility model is to provide a wheel bucket sand washing device to solve the problem that in the existing wheel bucket sand washing machine, small sand particles will remain inside the sand washing bucket during the sand washing process, occupying the internal space of the sand washing bucket, reducing the amount of sand scooped up by the sand washing bucket during the sand washing process, and thus reducing the sand washing efficiency of the wheel bucket sand washing machine.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A wheel-type sand washing device includes a drive assembly, a connecting assembly, and a sand washing assembly. The sand washing assembly includes a wheel bucket, a sand washing tank, and a pair of support seats. The pair of support seats are symmetrically arranged on the top of the left and right side walls of the sand washing tank. A wheel axle is provided at the center of the wheel bucket, and the axis of the wheel axle coincides with the axis of the wheel bucket. The two ends of the wheel axle are respectively rotatably mounted on the pair of support seats. Multiple sand washing buckets are evenly distributed along the circumferential side walls of the wheel bucket. The inner walls of the sand washing buckets are provided with grooves extending from the axis to the circumference on the left and right sides. The device also includes a scraper plate, with a first slider and a second slider symmetrically arranged on the left and right sides of the scraper plate. The scraper plate is slidably arranged in the sand washing bucket through the cooperation of the first slider and the second slider with the grooves on the left and right sides of the inner walls of the sand washing bucket. The drive assembly is connected to the wheel bucket through the connecting assembly to drive the wheel bucket to rotate. After the sand and gravel are thrown out, the scraper plate moves towards the opening of the sand washing bucket under the influence of gravity and centrifugal force, scraping away the residual sand and gravel in the sand washing bucket.

[0008] Furthermore, the drive assembly includes a reducer, a turntable, a transmission belt, and a motor; the turntable is coaxially fixed on the input shaft of the reducer, and the output shaft of the motor is connected to the turntable via the transmission belt; the output shaft of the reducer is connected to the bucket wheel drive.

[0009] Furthermore, the connecting assembly includes a first gear and a second gear; the first gear is coaxially fixed on the output shaft of the reducer, and the second gear is coaxially fixed on the left end of the wheel axle, with the first gear meshing with the second gear; the wheel axle is fixedly connected to the wheel bucket, and the output shaft of the reducer drives the wheel bucket to rotate through the meshing of the first gear and the second gear.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0011] In operation, a wheel-type sand washing device transmits power from a drive component to a connecting component, causing the wheel to rotate and perform sand washing. During the rotation of the wheel, multiple sand washing buckets on the surface of the wheel wash the sand and gravel inside the sand washing tank. During the discharge of sand and gravel after washing, the sand washing buckets continuously change their tilt angle according to the rotation of the wheel. When the tilt angle is too large, the sand and gravel inside the sand washing buckets will be thrown out by gravity and centrifugal force. At the same time, under the action of gravity and centrifugal force, the scraper plate inside the sand washing bucket moves towards the bucket opening to scrape off the small sand and gravel particles remaining in the sand washing bucket, preventing residual sand and gravel from occupying the internal space of the sand washing bucket and thus preventing a decrease in sand washing efficiency.

[0018] The technical solution of this embodiment will be clearly and completely described below with reference to the accompanying drawings, so as to provide a better understanding of the concept of this embodiment, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0019] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.

[0020] In the description of this utility model, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., are used only to indicate the orientation or positional relationship for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In the embodiments of this application, using Figure 1 Using the indicated direction as a reference, the side of the sand washing tank 7 with the triangular support 8 is the left side, and the side furthest from the triangular support 8 is the right side. For example... Figure 1 , Figure 2 and Figure 4 As shown, a wheel-type sand washing device includes a drive assembly, a connecting assembly, and a sand washing assembly. The sand washing assembly includes a wheel bucket 1, a sand washing tank 7, and a pair of support seats 16. The pair of support seats 16 are symmetrically arranged on the top of the left and right side walls of the sand washing tank 7. A wheel axle 15 is provided at the center of the wheel bucket 1, and the axis of the wheel bucket coincides with the axis of the wheel bucket. The two ends of the wheel axle 15 are respectively rotatably mounted on the pair of support seats 16. Multiple sand washing buckets 2 are evenly distributed along the circumferential side wall of the wheel bucket 1. The inner walls of the sand washing buckets 2 are provided with grooves 6 extending from the axis to the circumference on the left and right sides. The device also includes... Figure 3The scraper plate 3 shown has a first slider 4 and a second slider 5 symmetrically arranged on its left and right sides. The scraper plate 3 is slidably arranged in the sand washing hopper 2 by the first slider 4 and the second slider 5 respectively cooperating with the sliding grooves 6 on the left and right sides of the inner wall of the sand washing hopper 2.

[0022] The drive assembly is connected to the wheel bucket 1 via the connecting assembly, which drives the wheel bucket 1 to rotate. After the sand and gravel are thrown out, the scraper 3 moves towards the opening of the sand washing bucket 2 under the influence of gravity and centrifugal force, scraping away the residual sand and gravel in the sand washing bucket 2.

[0023] During operation, the operator first activates the drive assembly, which transmits power to the wheel bucket 1 via the connecting assembly, causing the wheel bucket 1 to rotate. As the wheel bucket 1 rotates, the sand washing buckets 2 are successively immersed in the water of the sand washing tank 7. Once immersed, the sand washing buckets 2 agitate the water flow and the sand and gravel within the tank. The impact of the water flow carries away some impurities from the surface of the sand and gravel. Due to the mutual collision and friction between the sand and gravel, further impurities adhering to the surface are removed. During this process, the scraper... 3. Under the action of water pressure, it moves to the bottom of the sand washing bucket 2. The sand washing bucket 2 scoops up the sand and gravel in the sand washing tank 7. After rotating, the sand washing bucket 2 gradually rises away from the water surface inside the sand washing tank 7. As the wheel bucket 1 rotates, the sand and gravel are thrown out from the bucket opening of the sand washing bucket 2 under the action of centrifugal force and gravity. The scraper 3 moves along the chute 6 towards the bucket opening of the sand washing bucket 2 under the influence of centrifugal force and gravity, scraping off the small sand and gravel particles remaining in the sand washing bucket 2, avoiding the residual sand and gravel occupying the internal space of the sand washing bucket 2, and thus avoiding low sand washing efficiency.

[0024] In some embodiments, such as Figure 1 As shown, the drive assembly includes a reducer 11, a turntable 10, a transmission belt 12, and a motor 9; the turntable 10 is coaxially fixed to the input end of the reducer 11, the output shaft of the motor 9 is connected to the turntable through the transmission belt 12, and the output shaft of the reducer 11 is connected to the wheel bucket 1 in a transmission connection.

[0025] The power output by the motor 9 can be transmitted to the reducer 11 through the transmission belt 12. After being reduced and increased in distance by the reducer 11, the power is transmitted to the wheel bucket 1 to drive the wheel bucket 1 to rotate, so as to meet the power requirements of the wheel bucket type sand washing device under high load conditions.

[0026] In some embodiments, such as Figure 2 and Figure 3 As shown, the connecting assembly includes a first gear 13 and a second gear 14; the first gear 13 is coaxially fixed on the output shaft of the reducer 11, and the second gear 14 is coaxially fixed on the left end of the wheel axle 15. The first gear 13 and the second gear 14 mesh, and the wheel axle 15 is fixedly connected to the wheel bucket 1. The output shaft of the reducer 11 drives the wheel bucket to rotate through the meshing of the first gear 13 and the second gear 14.

[0027] Through the meshing of the first gear 13 and the second gear 14, the power output by the drive component is transmitted to the wheel axle 15 which is fixedly connected to the second gear 14, thereby driving the wheel bucket 1 to perform sand washing work. This can achieve higher efficiency in mechanical energy transmission, and because the gears have a large load-bearing capacity, they can support the wheel bucket sand washing device to clean heavy sand and gravel.

[0028] In this embodiment, the sand washing tank 7 is connected to a triangular bracket 8 on the left side. The motor 9, reducer 11, and turntable 10 are installed above the triangular bracket 8, which enables the drive assembly, connecting assembly, and sand washing assembly to form an integrated structure, facilitating the handling and storage of the equipment.
