Technical Field

[0001] This utility model relates to the field of sand and gravel cleaning technology, specifically a device for cleaning the surface of recycled sand and gravel. Background Technology

[0002] With the rapid development of the construction industry, the demand for building materials such as sand and gravel is increasing. Natural sand and gravel resources are becoming increasingly scarce. Recycled sand and gravel, as a sustainable resource, is being used more and more widely. However, during the production process, recycled sand and gravel often have a large amount of impurities such as mud, dust, and old mortar attached to their surface. These impurities will seriously affect the performance and subsequent use of recycled sand and gravel. Therefore, workers usually use recycled sand and gravel surface cleaning equipment to clean the dust on the surface of the sand and gravel, thereby improving the quality of recycled sand and gravel.

[0003] Because the gaps between sand and gravel are large, when cleaning sand and gravel, you only need to put it in water and lift it back and forth, and the water can wash away the mud and dust on its surface. However, if the sand and gravel are removed directly after cleaning, a large amount of water will drip onto the ground, making the construction site muddy. Existing cleaning devices do not have water control functions. Therefore, a recycled sand and gravel surface cleaning device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a surface cleaning device for recycled sand and gravel to solve the problem mentioned in the background art that the existing cleaning devices do not have water control function.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A surface cleaning device for recycled sand and gravel includes a cleaning tank and a drain valve fixedly connected to the bottom of the cleaning tank. Multiple fixed blocks arranged in a polar axis are fixedly connected to the bottom inner side of the cleaning tank. A vertically arranged limiting rod is fixedly connected to the top of each fixed block. A return spring is provided on the outer side of the limiting rod. A mounting plate is threadedly connected to the top of the limiting rod. A storage assembly installed on the outer side of the limiting rod is located below the mounting plate.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A surface cleaning device for recycled sand and gravel includes a cleaning tank 1 and a drain valve 2 fixedly connected to the bottom of the cleaning tank 1. Multiple fixed blocks 3 arranged in a polar axis are fixedly connected to the bottom inner side of the cleaning tank 1. Vertically positioned limiting rods 4 are fixedly connected to the top of the fixed blocks 3. Return springs 5 ​​are provided on the outer side of the limiting rods 4. A mounting plate 6 is threadedly connected to the top of the limiting rods 4. A storage assembly 7 is installed below the mounting plate 6, mounted on the outer side of the limiting rods 4. A storage mesh tube 8 is provided at the top of the storage assembly 7. Multiple sets of support assemblies 9 arranged in a polar axis are installed on the outer side of the cleaning tank 1. The outer diameter of the limiting rods 4 is smaller than the inner diameter of a circular hole 72, and the limiting rods 4 are inserted into the inner side of the circular hole 72. The top of the return spring 5 is in contact with the bottom of the storage plate 71, and the bottom of the return spring 5 is fixedly connected to the top of the fixed blocks 3. The storage mesh tube 8 is located inside multiple clamping plates 73 and is in contact with the inner side of the clamping plates 73. The support component 9 includes a connecting frame 91 fixedly connected to the outside of the cleaning tank 1. An insert plate 92 is slidably connected to the inside of the connecting frame 91, passing through the cleaning tank 1 and slidably connected to it. Through the fixed block 3, limit rod 4, return spring 5, mounting plate 6, placement component 7, placement net tube 8, support component 9, connecting frame 91 and insert plate 92, when cleaning sand and gravel, the placement net tube 8 is placed on top of the placement plate 71, and the placement net tube 8 is pulled back and forth to clean the mud and dust off the surface of the recycled sand and gravel. After cleaning, the placement net tube 8 is pulled so that the placement plate 71 is higher than the cleaning tank, the insert plate 92 is pushed and the placement net tube 8 is released, and the insert plate 92 can support the placement plate 71. The water in the placement net tube 8 can drip into the inside of the cleaning tank 1 through the round hole 72, thereby draining the water in the placement net tube 8 and preventing a large amount of water from falling on the construction site.

[0024] The storage assembly 7 includes a storage plate 71 located outside the limiting rod 4. A vertically penetrating circular hole 72 is formed inside the storage plate 71. Multiple retaining plates 73 are fixedly connected to the top of the storage plate 71. Water-retaining rings 74 are fixedly connected to the upper and lower edges of the storage plate 71 on the outer side of the retaining plates 73. Multiple vertically arranged water-guiding plates 75 are fixedly connected to the bottom of the lower water-retaining ring 74. The outer diameter of the storage plate 71 is smaller than the inner diameter of the washing tub 1, and there are multiple circular holes 72. The round holes 72 are evenly distributed inside the shelf 71. When water is controlled by the shelf assembly 7, shelf 71, round holes 72, retaining plate 73, water-blocking ring 74 and water-guiding plate 75, the water-blocking ring 74 can restrict the water so that the water only flows down from the round holes 72. The water-guiding plate 75 can guide the water from the edge of the shelf 71 into the inside of the washing tank 1. The shelf assembly 7 can prevent water from flowing down the outside of the washing tank 1 when water is controlled, thus ensuring the dryness of the site.

[0025] Workflow: Before using the device, install all components. First, install the mounting assembly 7. Place the placement plate 71 above the cleaning tank 1 and align the corresponding circular hole 72 vertically with the limiting rod 4. Press down the placement plate 71 so that the limiting rod 4 passes through the circular hole 72, and ensure that the top of the return spring 5 is tightly fitted to the bottom of the placement plate 71. Then, screw the mounting plate 6 onto the top of the limiting rod 4 to create a threaded connection between the mounting plate 6 and the limiting rod 4. Next, add an appropriate amount of water to the cleaning tank 1 and pour regeneration fluid into the inner side of the placement mesh cylinder 8. After removing the sand and gravel, place the storage net tube 8 inside the clamping plate 73 at the top of the storage plate 71, so that the outer side of the storage net tube 8 is in contact with the inner side of the clamping plate 73. When the storage net tube 8 is released, the storage plate 71 slides downward outside the limiting rod 4, and the return spring 5 at the top of the fixing block 3 is compressed, and the storage net tube 8 gradually sinks into the water. When the storage net tube is completely submerged in the water, pull the storage net tube 8 upward. The return spring 5 returns to its original position, causing the storage plate 71 to slide upward outside the limiting rod 4. Repeat this lifting and pulling motion to remove the mud and ash from the surface of the recycled sand and gravel. After cleaning, pull the storage net cylinder 8 so that the storage plate 71 is higher than the cleaning cylinder. Push the insert plate 92 inside the connecting frame 91 so that the insert plate 92 moves below the storage plate 71. At this time, release the storage net cylinder 8, and the insert plate 92 can support the storage plate 71. The water in the storage net cylinder 8 can drip into the inside of the cleaning bucket 1 through the round hole 72, thereby draining the water in the storage net cylinder 8 and preventing a large amount of water from falling on the construction site. When controlling the water, the water-blocking ring 74 can restrict the water flow, so that the water only flows out through the round hole 72. Downstream, the water guide plate 75 can guide the water from the edge of the storage plate 71 into the inside of the cleaning tank 1. The storage component 7 can prevent water from flowing down the outside of the cleaning tank 1 during water control, thus ensuring the dryness of the site. The support component 9 and the reset spring 5 make it easier to lift the storage net cylinder 8, making it easier for workers to drain the water in the storage net cylinder 8. After the device has been used for a period of time, the drain valve 2 can be opened to collect the sewage for unified treatment. Then, clean water can be added to continue cleaning the sand and gravel.
