Description

Technical Field

[0001] This utility model relates to the field of sand and gravel aggregate processing technology, specifically to a sand and gravel aggregate conveying and washing device. Background Technology

[0002] During the production and transportation of sand and gravel aggregates, contaminants such as mud, dust, and organic impurities often adhere to the surface of the sand and gravel due to processes such as mining, crushing, and screening. These impurities affect the quality of the aggregates, and consequently, the strength and durability of concrete. Sand and gravel need to undergo a washing process before being used or during production. The purpose of this process is to remove dust from the surface of the sand and gravel. Furthermore, the friction between sandpaper and sandpaper breaks down the moisture layer covering the surface of the sand and gravel, thus achieving a further cleaning effect. Currently, the main types of sand washing machines on the market include drum-type sand washing machines.

[0003] The drum-type sand washing machine mainly uses a conveying auger to continuously transport sand and gravel from the feed port to the discharge port. The spray nozzles of the existing sand and gravel aggregate conveying water washing device are usually installed at a fixed angle, resulting in a limited water flow coverage area. Some sand and gravel cannot be fully washed. Furthermore, due to the uneven distribution of sand and gravel in the sand washing machine, the fixed spray angle will cause some areas to have too much water while other areas have insufficient water, affecting the cleaning effect. Utility Model Content

[0004] The purpose of this utility model is to provide a sand and gravel aggregate conveying water washing device to solve the problems mentioned in the background art. The spray nozzles of the existing sand and gravel aggregate conveying water washing devices are usually installed at a fixed angle, resulting in a limited water flow coverage area. Some sand and gravel cannot be fully washed. Furthermore, due to the uneven distribution of sand and gravel in the sand washing machine, a fixed spray angle will cause some areas to have excessive water volume while other areas have insufficient water volume, affecting the cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel aggregate conveying and washing device, comprising a support frame and a spraying unit:

A rotating frame is mounted on the end of the spray pipe away from the arc-shaped limiting frame. The rotating frame is rotatably connected to the side of the arc-shaped limiting frame. A nozzle is mounted at the bottom of the spray pipe. The spray pipe slides within the arc-shaped limiting frame to control the spray angle of the nozzle.

[0007] By adopting the above technical solution, continuous conveying of sand and gravel aggregates can be achieved, and the spraying angle of the spray nozzle can be adjusted by sliding the spray pipe within the arc-shaped limiting frame, making water washing more uniform and efficient.

At the same time, the setting of multiple nozzles can expand the spraying range.

[0012] Preferably, the support frame also has a rotating shaft disposed on the side of the support frame, which is embedded in the bottom of the rotating frame and rotatably connected to the rotating frame.

[0013] By adopting the above technical solution, the spray pipe can be flexibly oscillated within the arc-shaped limiting frame through the cooperation of the rotating shaft and the rotating frame, thereby further optimizing the spray angle adjustment of the nozzle.

[0014] Preferably, the spray unit also has a slide rail disposed inside the support frame, and a movable frame is slidably disposed inside the slide rail.

[0016] Preferably, the spray unit also has a slide bar disposed at one end of the spray pipe, the slide bar being embedded in a slide rail and slidably connected to the slide rail.

[0017] By adopting the above technical solution, the displacement of the spray pipe can be replaced by the sliding of the slide rod in the slide rail, so that the spray pipe slides along the arc-shaped limit frame and rotates its own angle.

At the same time, the discharge port 102 facilitates the discharge of the washed material.

[0031] The spray section 2 is located inside the support frame 1. The spray section 2 has an arc-shaped limiting frame 201 located inside the support frame 1. A spray pipe 202 is slidably arranged on the side of the arc-shaped limiting frame 201. A rotating frame 203 is arranged at the end of the spray pipe 202 away from the arc-shaped limiting frame 201. The rotating frame 203 is rotatably connected to the side of the arc-shaped limiting frame 201. A nozzle 205 is arranged at the bottom of the spray pipe 202. The spray pipe 202 slides in the arc-shaped limiting frame 201 to control the spray angle of the nozzle 205. This can realize the continuous conveying of sand and gravel aggregates. By sliding the spray pipe 202 in the arc-shaped limiting frame 201, the spray angle of the nozzle 205 can be adjusted, making the water washing more uniform and efficient.

[0032] Example 2

[0033] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a sand and gravel aggregate conveying and washing device, including a spray section 2, an arc-shaped limiting frame 201, and a spray pipe 202.

[0034] The spray unit 2 also has a connecting pipe 206 at one end of the spray pipe 202. The spray pipe 202 is connected to a plurality of nozzles 205 at the bottom of the spray pipe 202. The connecting pipe 206 is connected to an external water pump. Water supplied by the water pump can be delivered to the spray pipe 202 through the connecting pipe 206 and sprayed evenly by the nozzles 205 to improve the washing effect. At the same time, the setting of multiple nozzles 205 can expand the spray range.

[0035] A rotating shaft 103 is fixedly installed on the side of the support frame 1. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The rotating shaft 103 is embedded in the bottom of the rotating frame 203 and rotates and is connected to the rotating frame 203. Through the cooperation of the rotating shaft 103 and the rotating frame 203, the spray pipe 202 can swing flexibly within the arc-shaped limiting frame 201, further optimizing the spray angle adjustment of the nozzle 205.

[0036] A slide rail 208 is fixedly installed inside the support frame 1. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. A movable frame 207 is slidably installed inside the slide rail 208, which allows the movable frame 207 to move laterally along the slide rail 208.

[0037] A slide rod 204 is integrally provided at one end of the spray pipe 202. The slide rod 204 is embedded in the slide rail 208 and slidably connected to the slide rail 208. The slide rod 204 can slide in the slide rail 208 to replace the displacement of the spray pipe 202, so that the spray pipe 202 slides along the arc-shaped limit frame 201 and rotates its own angle.

[0038] A lead screw 209 is laterally rotatable inside the slide rail 208, and a motor b210 is installed on the outside of the support frame 1. The output end of the motor b210 is connected to the lead screw 209. The lead screw 209 passes laterally through the movable frame 207 and is nested and threadedly connected to the movable frame 207. The motor b210 can drive the lead screw 209 to rotate, thereby driving the movable frame 207 to move precisely along the slide rail 208, thus accurately controlling the position of the spray pipe 202.

[0039] Working principle: First, start motor a108, which drives threaded rod a104 to rotate. Through the meshing transmission of gears a105 and b107, threaded rod b106 rotates synchronously, thereby pushing the sand and gravel aggregate forward within the support frame 1. Simultaneously, an external water pump supplies water to spray pipe 202 through connecting pipe 206. The water flows through nozzle 205 and is evenly sprayed onto the surface of the sand and gravel aggregate for efficient cleaning. Next, start motor b210, which drives screw 209 to rotate, causing the moving frame 207 to move along slide rail 20. 8. Lateral movement allows the spray pipe 202 to slide within the slide rail 208 via the slide rod 204. Simultaneously, the spray pipe 202 slides within the arc-shaped limiting frame 201 and adjusts the spray angle with the help of the rotating frame 203 and the rotating shaft 103, thereby increasing the spray range of the nozzle 205 and improving the cleaning uniformity. The cleaned sand and gravel aggregate is discharged from the discharge port 102, completing the entire water washing process. This device achieves efficient and uniform sand and gravel aggregate cleaning by automatically adjusting the spray angle and spray position, and is suitable for different working conditions.
