Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying machine technology, specifically a construction spraying machine. Background Technology
[0002] The working principle of a concrete spraying machine is mainly to use compressed air to spray concrete of a certain proportion onto the construction surface through a conveying pipeline to form a concrete support layer. Concrete spraying machines are mainly divided into two types: dry spraying machines and wet spraying machines.
[0003] Wet shotcrete machines deliver pre-mixed concrete mix to the nozzle via pneumatic pumps or concrete pumps. The mixed concrete is then pumped to the nozzle, and compressed air is applied at the pump outlet to ensure thorough mixing of the material and air in the pipeline. This results in better uniformity of the sprayed material, lower rebound rate, and lower dust concentration, which is beneficial to worker health and has lower shotcrete costs. However, the increased viscosity of the slurry in wet shotcrete due to water mixing causes it to adhere to the hopper, leading to slurry residue during sandblasting. Utility Model Content
[0004] The purpose of this invention is to provide a construction spraying machine to solve the above problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction spraying machine, characterized in that it comprises;

[0024] Please see Figure 1-3 This utility model provides a technical solution: a construction spraying machine, comprising;
[0025] The mortar spraying machine body 100 is equipped with a slurry falling and sinking structure, which includes a mortar pipe 200, a hopper cover 300, a mortar hopper 400, a vibrating motor 403, and a spring 404.
[0026] The mortar spraying machine body 100 has a mortar pipe 200 on the outside and a high-pressure air pump inside the mortar spraying machine body 100. One end of the mortar pipe 200 is connected to the high-pressure air pump inside the mortar spraying machine body 100.
[0027] The hopper cover 300 is funnel-shaped and is located at the top of the mortar pipe 200. The bottom of the hopper cover 300 is connected to the top of the mortar pipe 200. The mortar hopper 400 is fitted on the outside of the hopper cover 300. There is a gap between the hopper cover 300 and the mortar hopper 400. There are multiple springs 404. The springs 404 are located between the hopper cover 300 and the mortar hopper 400. The two ends of the springs 404 are respectively connected to the hopper cover 300 and the mortar hopper 400.
[0028] The top of the mortar hopper 400 has a feed plate 401, and the bottom of the outer wall of the feed plate 401 has multiple vibrating motors 403.
[0029] Furthermore, the mortar hopper 400 and the feed plate 401 are an integral structure. The feed plate 401 is funnel-shaped, and its diameter is larger than that of the hopper cover 300. This effectively prevents materials from entering the interior of the hopper cover 300 when materials are fed, thus avoiding the spring 404 between the hopper cover 300 and the mortar hopper 400 from being affected.
[0030] Furthermore, the bottom of the mortar hopper 400 has a discharge pipe 402. The mortar hopper 400 and the discharge pipe 402 are an integral fixed structure. The discharge pipe 402 and the mortar hopper 400 are combined to form a funnel shape. Therefore, the material inside the mortar hopper 400 is directionally fed along the inner wall of the mortar hopper 400 and the discharge pipe 402.
[0031] Furthermore, the mortar spraying machine body 100 has a handle 101 on its outer side, and the handle 101 is covered with an anti-slip sleeve. Multiple heat dissipation grooves are provided on the bottom side of the mortar spraying machine body 100 to dissipate heat from the high-pressure air pump inside the mortar spraying machine body 100.
[0032] Furthermore, one end of the mortar pipe 200 has a mud spray pipe 500, one end of which has a mud nozzle 501, and the other end of the mud spray pipe 500 has a mud hose 503. The two ends of the mud hose 503 have pipe connectors A502 and B504, respectively. The mud hose 503 can be connected to the mud spray pipe 500 through pipe connector A502, and to the mortar pipe 200 through pipe connector B504. The mud hose 503 is coiled inside the mortar pipe 200, and the mud spray pipe 500 is embedded in one end of the mortar pipe 200. The mud spray pipe 500 can be pulled out from inside the mortar pipe 200, thereby pulling out the mud hose 503. The mud hose 503 serves as an extension of the mud spray pipe 500, allowing workers to hold the mud spray pipe 500 and spray it onto the wall, providing flexibility.
[0033] Working principle: During use, materials are fed through the feeding disc 401, which is funnel-shaped and has a diameter larger than that of the hopper cover 300. This effectively prevents materials from entering the hopper cover 300 and avoids affecting the spring 404 between the hopper cover 300 and the mortar hopper 400. The mortar hopper 400 stores the materials. Then, the vibration motor 403 is started to continuously vibrate the mortar hopper 400, causing... The mortar hopper 400 is shaken inside the hopper cover 300. During the shaking, the slurry inside the mortar hopper 400 flows downward to prevent the slurry from adhering to the inner wall of the mortar hopper 400 and causing accumulation. The slurry flows downward inside the mortar hopper 400 to the mortar pipe 200. The high-pressure air pump inside the mortar spraying machine body 100 is started to pressurize the slurry. The slurry inside the mortar pipe 200 passes through the slurry hose 503 and the slurry spraying pipe 500 and is sprayed out through the slurry nozzle 501.
[0034] Furthermore, the mud hose 503 is coiled inside the mortar pipe 200, and the mud spray pipe 500 is embedded in one end of the mortar pipe 200. The mud spray pipe 500 can be pulled out from inside the mortar pipe 200, thereby pulling out the mud hose 503. The mud hose 503 serves as an extension of the mud spray pipe 500. Workers can hold the mud spray pipe 500 and aim it at the wall to spray, making it flexible to use.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
