Description

Technical Field

[0001] This utility model relates to the field of road sweeping technology, and in particular to a high-efficiency dust suction and filtration device for a small road sweeper. Background Technology

[0002] The high-efficiency dust collection and filtration device for small road sweepers is a specialized design for these vehicles. It efficiently collects and filters dust and fine particulate matter generated during the sweeping process. This device is widely used in cleaning operations in city streets, parks, squares, factory workshops, and other locations. Its high-efficiency dust collection and filtration performance effectively improves environmental quality, reduces dust pollution, and provides strong support for urban sanitation and industrial production.

[0003] Existing high-efficiency dust collection and filtration devices for small road sweepers filter and collect impurities through a filter screen during use. However, the filter screen is usually installed using bolts, which makes the installation process cumbersome and inefficient, thus affecting the cleaning efficiency of the road sweeper. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a high-efficiency dust collection and filtration device for a small road sweeper, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-efficiency dust collection and filtration device for a small road sweeper, including a sweeper body. A fixed box is fixedly installed on the inner wall of the sweeper body, and a movable box is slidably connected to the inner wall of the sweeper body. An opening is provided on the side of the fixed box and the movable box that are close to each other. A sealing seat is provided on the side of the fixed box and the movable box that are close to each other. A filter screen is fixedly installed in the middle of the sealing seat. An exhaust assembly is provided on one side of the fixed box. A corrugated pipe section is fixedly installed on one side of the movable box. An air suction hood is fixedly installed at one end of the corrugated pipe section. The top of the fixed box... A motor is fixedly installed, and a lead screw is fixedly installed on one side of the motor via a coupling. A connecting plate threadedly connected to the lead screw is fixedly installed on the top of the movable box. The technical effect achieved by the above solution is that the motor drives the lead screw to rotate, and the rotation of the lead screw drives the guide rod, causing the threaded connecting plate to move, thereby moving the movable box and separating it from the fixed box. This relaxes the limit on the sealing seat between the movable box and the fixed box, making it easier for workers to replace the filter screen and greatly improving efficiency.

[0007] Preferably, in any of the above solutions, a guide rod is fixedly installed on the inner wall of the sweeper body, and the movable box is slidably connected to the guide rod. The guide rod is T-shaped. The technical effect achieved by adopting the above solution is that the guide rod can guide the movable box during its movement, thereby enabling the movable box to move more stably.

[0008] Preferably, in any of the above solutions, sealing grooves are provided on both sides of the sealing seat, a first sealing block is fixedly installed on the inner wall of the sealing groove, and a compression block is fixedly installed on the side of the fixed box and the movable box with the opening. The technical effect achieved by the above solution is that when the movable box moves towards the fixed box, the compression block enters the interior of the sealing groove and compresses the first sealing block, thereby greatly improving the sealing performance between the sealing seat and the fixed box and the movable box.

[0009] Preferably, one side of the sealing seat is fixedly connected to an auxiliary positioning cover, the outer dimensions of which are the same as the inner wall dimensions of the fixed box. The technical effect achieved by the above solution is that by first inserting the auxiliary positioning cover into the inside of the fixed box, the position of the sealing seat can be initially positioned, and then the position of the sealing seat can be positioned by moving the moving box.

[0010] Preferably, the inner wall of the mobile box is fixedly connected to a guide slant seat, one side of which contacts the filter. The technical effect achieved by the above solution is that the collected dust can be guided and accumulated on one side of the mobile box by the guide slant seat, which can reduce the amount of collected dust falling into the interior of the cleaning vehicle when the sealing seat is disassembled.

[0011] Preferably, one of the above solutions is that a cleaning port is provided on one side of the mobile box, and a disassembly door is fixedly installed on the inner wall of the cleaning port. The technical effect achieved by the above solution is that by disassembling the disassembly door, the staff can recycle the dust collected inside the mobile box.

[0012] Preferably, one side of the movable box has a sealing groove, one side of the disassembly door has a sealing plate fixedly installed, and one side of the sealing plate has a second sealing block fixedly installed. The technical effect achieved by the above solution is that when the disassembly door is reinstalled, the sealing plate enters the interior of the sealing groove and applies pressure to the second sealing block, thereby improving the sealing between the disassembly door and the movable box. The exhaust assembly includes an air pump and an air intake pipe connected to the fixed box, thereby enabling adsorption filtration.

The motor 9 drives the lead screw 10 to rotate, and the rotation of the lead screw 10 drives the guide rod 12 to move the connecting plate 11, thereby moving the movable box 3. The movable box 3 separates from the fixed box 2, thereby releasing the limit on the sealing seat 5 between the movable box 3 and the fixed box 2. Then, the operator can replace the filter screen 6, making the replacement of the filter screen 6 more convenient and greatly improving efficiency.

[0025] As an optional technical solution of this utility model, a guide rod 12 is fixedly installed on the inner wall of the sweeper body 1, and the moving box 3 is slidably connected to the guide rod 12. The guide rod 12 is T-shaped. The guide rod 12 can guide the moving box 3 when it is moving, so that the moving box 3 can move more stably.

[0026] As an optional technical solution of this utility model, sealing grooves 13 are provided on both sides of the sealing seat 5. A first sealing block 14 is fixedly installed on the inner wall of the sealing groove 13. A pressing block 15 is fixedly installed on one side of the fixed box 2 and the movable box 3 with the opening 4. When the movable box 3 moves towards the fixed box 2, the pressing block 15 enters the interior of the sealing groove 13 and presses the first sealing block 14, thereby greatly improving the sealing performance between the sealing seat 5 and the fixed box 2 and the movable box 3.

[0027] As an optional technical solution of this utility model, an auxiliary positioning cover 16 is fixedly connected to one side of the sealing seat 5. The outer dimensions of the auxiliary positioning cover 16 are the same as the inner wall dimensions of the fixed box 2.

The exhaust assembly includes an air pump and an air intake pipe connected to the fixed box 2, thereby enabling adsorption filtration.

[0031] A high-efficiency dust collection and filtration device for a small road sweeper operates as follows: A motor 9 drives a lead screw 10 to rotate. The rotation of the lead screw 10, in turn, drives a guide rod 12, causing the threaded connecting plate 11 to move, thus moving the movable box 3. The movable box 3 separates from the fixed box 2, releasing the limiting position of the sealing seat 5 between them. This allows for easier replacement of the filter screen 6 by the operator, significantly improving efficiency.

[0032] In summary, this high-efficiency dust collection and filtration device for a small road sweeper, through the cooperation between the sweeper body 1, fixed box 2, movable box 3, opening 4, sealing seat 5, filter screen 6, corrugated pipe 7, suction hood 8, motor 9, lead screw 10, and connecting seat 11, enables the motor 9 to drive the lead screw 10 to rotate, thereby separating the movable box 3 from the fixed box 2. This relaxes the restriction on the sealing seat 5 between the movable box 3 and the fixed box 2, making it easier to replace the filter screen 6 and greatly improving efficiency. The cooperation between the sealing groove 13, the first sealing block 14, and the squeezing block 15 increases the sealing between the fixed box 2 and the movable box 3, thus making the dust collection and filtration effect of the sweeper better during sweeping operations.

[0033] Example 2: A high-efficiency dust collection and filtration device for a small road sweeper. In this example, the motor 9 is replaced with a cylinder, which drives the moving box 3 to move.
