Description

Technical Field

[0001] The utility model relates to the technical field of river sand conveying, and more specifically, to a river sand conveying device. Background Art

[0002] In the building materials industry, as an important raw material, the conveying efficiency and quality of river sand directly affect the production efficiency and product quality. Existing river sand conveying devices often have problems such as complex structures, high maintenance costs, and low conveying efficiency. At the same time, the remaining river sand adhered to the conveyor belt during the conveying process is likely to fall off, directly falling on the processing site, causing environmental pollution, posing safety hazards, and being troublesome to clean.

[0003] The existing patent CN218808538U discloses a river sand conveying device that conveys fine sand and coarse stones separately through a first conveying component and a second conveying component, and the second conveying component can adjust the position and direction as needed, which is convenient to use. The coarse stones are blocked by a partition component to prevent the coarse stones from bouncing onto the conveyor belt due to vibration, damaging the conveyor belt and affecting the product quality. The baffle component can prevent the coarse stones from falling to the ground, facilitating the transfer of the coarse stones by the staff. Although this device has many beneficial effects, some river sand will still adhere to the conveyor belt during the conveying process. Especially in windy weather, it is more likely to fall onto the construction site. In view of this, we propose a river sand conveying device. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment:

[0022] Please refer toFigures 1-3 , a river sand conveying device, including a sand screening machine 1. A conveying mechanism 2 is arranged below the sand outlet of the sand screening machine 1. The conveying mechanism 2 is used to convey river sand to the target position. A cleaning mechanism 3 is arranged at a position near the bottom surface of the other end of the conveying mechanism 2. The cleaning mechanism 3 is used to clean the conveying mechanism 2 after the river sand has been conveyed, preventing the residual river sand from floating into the air. A collection box 4 is arranged below the cleaning mechanism 3. The top surface of the collection box 4 is in contact with both sides of the conveying mechanism 2. The collection box 4 is used to collect the river sand cleaned by the cleaning mechanism 3.

[0023] The cleaning mechanism 3 includes a rotary brush 301. Installation blocks 302 are rotatably connected to both sides of the rotary brush 301. Installation grooves 401 are opened on both sides of the top surface of the collection box 4. The installation blocks 302 extend into the installation grooves 401. An elastic member is arranged at the bottom of the installation grooves 401. The elastic member can be set as a spring or a spring telescopic rod. Through the setting of the elastic member, an elastic supporting force is provided for the rotary brush 301, facilitating the contact between the rotary brush 301 and the conveying mechanism 2. The installation blocks 302 are in sliding fit with the installation grooves 401. A motor 303 is arranged at the top of one of the installation blocks 302. The output shaft of the motor 303 is connected to the central axis of the rotary brush 301. The motor 303 is used to drive the rotary brush 301 to rotate and clean the conveying mechanism 2. The rotation direction of the rotary brush 301 is opposite to the movement direction below the conveying mechanism 2, facilitating a better cleaning effect.

[0024] In a possible embodiment, a scraper is arranged on one side of the rotary brush 301. Both ends of the scraper are installed at the upper opening of the collection box 4. The scraper is located at the rear side of the rotation direction of the rotary brush 301. As Figure 1 shown, if the conveyor belt 201 conveys upward, the rotary brush 301 rotates to the right, and the scraper is arranged on the left side of the rotary brush 301. Through the setting of the scraper, the rotary brush 301 that has brushed the lower surface of the conveyor belt 201 is scraped, and the river sand brought in by the rotary brush 301 is scraped off.

[0025] In this application, the conveying mechanism 2 includes a conveyor belt 201 and a mounting frame 203. The drive of the conveyor belt 201 is prior art and will not be elaborated here. The conveyor belt 201 is arranged on the mounting frame 203. Anti-slip strips 202 are arranged oppositely on both sides of the conveyor belt 201. The inner side surface of the anti-slip strips 202 is set as an inclined surface. The setting of the anti-slip strips 202 and the inclined surface facilitates the river sand at the edge of the conveyor belt 201 to leave towards the inner side of the conveyor belt 201, preventing the river sand from falling between the conveyor belt 201 and the mounting frame 203. The conveyor belt 201 is made of wear-resistant material, reducing wear, extending the service life, and reducing the maintenance cost.

[0026] As Figure 2As shown in the figure, the rotary brush 301 is arranged below the conveyor belt 201 near the end. When the conveyor belt 201 rotates downward after transporting the river sand, the rotary brush 301 brushes off the river sand remaining on the downward-facing surface of the conveyor belt 201, and the fallen river sand will fall into the lower collection box 4.

[0027] In a possible embodiment, a partition is arranged between two oppositely arranged baffles 202 to facilitate the transportation of river sand on the surface of the conveyor belt 201 and prevent the river sand from slipping backward during transportation.

[0028] In this application, multiple sets of support legs 204 are arranged at the bottom of the mounting frame 203. The support legs 204 are of telescopic structure. Through the arrangement of the telescopic structure, the inclination angle of the conveying mechanism 2 can be adjusted, and the support legs 204 are rotatably connected to the bottom of the mounting frame 203 for corresponding adjustment according to the target position to be conveyed.

[0029] In this application, a filter screen assembly is arranged in the sand screening machine 1. Through the arrangement of the filter assembly, the coarse river sand is filtered to separate the coarse river sand from the fine river sand, and a coarse river sand outlet is provided. The coarse river sand flows out from the coarse river sand outlet, and a conveying mechanism 2 is also arranged at the outlet of the coarse river sand to convey the coarse river sand to different positions.

[0030] In this application, baffles 205 are arranged on both sides of the mounting frame 203 to prevent the river sand from splashing outside the conveyor belt 201. Among them, the two baffles 205 can be arranged as arc-shaped structures bent inward, which is convenient for preventing the river sand from splashing outward and at the same time enabling the river sand splashed on the baffles 205 to flow downward onto the conveyor belt 201.

[0031] Working principle: When the device is in use, the river sand flows into the top surface of the conveying mechanism 2 through the sand screening machine 1, and the conveying mechanism 2 conveys the river sand to the target position. As Figure 1 shown, the river sand flows into the top surface of the conveyor belt 201 from the sand screening machine 1 and is conveyed from the left end to the right end of the conveyor belt 201. When the part of the conveyor belt 201 that has transported the river sand rotates to the lower side, the motor 303 drives the rotary brush 301 to rotate. The rotary brush 301 brushes off the river sand remaining on the downward-facing surface of the conveyor belt 201, and the fallen river sand will fall into the lower collection box 4. In this application, an elastic member is arranged in the installation groove 401, and an elastic supporting force is provided to the rotary brush 301 through the elastic force of the elastic member, which is convenient for the bristles of the rotary brush 301 to be in close contact with the conveyor belt 201 and is convenient for brushing off the river sand remaining on the conveyor belt 201. By arranging the baffles 205 on both sides of the mounting frame 203 and the baffles 205 being arc-shaped structures bent inward, it is convenient for preventing the river sand falling on the conveyor belt 201 from splashing outward and at the same time enabling the river sand splashed on the inner side of the baffles 205 to flow downward along the inner wall onto the conveyor belt 201.
