Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figs. 1-3As shown, this application discloses a mud and sand mixing device for construction engineering, including a mixing drum 1, a mounting frame 6 for fixing the mixing drum 1, a motor 11 mounted on the upper end of the mounting frame 6, a rotating rod 12 extending into the mixing drum 1 from the lower end of the motor 11, and a mixing blade 16 connected to the rotating rod 12. A transparent cover 14 that can move up and down is installed on the upper end of the mixing drum 1 to facilitate observation of the mixing situation inside the mixing drum 1. The rotating rod 12 passes through the middle part of the transparent cover 14. A support ring 5 and a collar 13 that are fitted together to form a ring are slidably inserted into the middle part of the transparent cover 14. Rubber sheets 4 are fixed to the inner walls of the support ring 5 and the collar 13. The upper end of the rubber sheet 4 contacts the outer surface of the rotating rod 12. The mixing drum 1 is used to pour in cement, sand and water. After mixing in the correct proportion, the motor 11 drives the rotating rod 12 and the mixing blade 16 to rotate, mixing the cement and sand until the mixture is complete. To avoid mixing the mud... During the sand mixing process, cement dust splashes out. A transparent cover 14 is installed at the upper end of the mixing drum 1, with the bottom end of the transparent cover 14 fitting against the upper end of the mixing drum 1 to shield the upper end of the mixing drum 1. This prevents excessive pollution caused by cement dust splashing during the mixing of mud and sand, reducing the impact on the surrounding environment. By setting a support ring 5 and a collar 13 at the upper end of the transparent cover 14, the rubber sheet 4 on the inner wall of the support ring 5 and the collar 13 contacts the outer surface of the rotating rod 12. This not only shields the upper end of the transparent cover 14 but also prevents the rotating rod 12 from directly contacting and rubbing against the transparent cover 14. Furthermore, during the rotation of the rotating rod 12 and its contact and friction with the rubber sheet 4, the elasticity of the rubber sheet 4 causes its upper end to contact the outer surface of the rotating rod 12, adapting to the situation where the upper end of the rubber sheet 4 becomes thinner due to friction. In addition, by moving the transparent cover 14, support ring 5, and collar 13 upwards, the upper end of the mixing drum 1 can be opened, making it convenient to pour in cement dust, sand, and water for mixing.

[0022] To connect the support ring 5 and the collar 13 together, positioning rods 18 are fixed at both ends of the support ring 5, and insertion holes 17 are opened at both ends of the collar 13. The two positioning rods 18 are inserted into the two insertion holes 17 respectively. The positioning rods 18 at the end of the support ring 5 are inserted into the insertion holes 17, so that the support ring 5 and the collar 13 are connected to form a ring. Moving the support ring 5 causes the positioning rods 18 to disengage from the insertion holes 17, so that the support ring 5 and the collar 13 can be separated.

[0023] A fixing seat 7 is fixed on the upper surface of the transparent cover 14, and a bolt 15 is threadedly connected between the support ring 5 and the fixing seat 7. In order to facilitate the connection between the support ring 5 and the transparent cover 14, the support ring 5 and the collar 13 can be moved upward and removed from the transparent cover 14 by removing the bolt 15. Then the collar 13 and the support ring 5 can be separated for replacing the rubber sheet 4. The bottom end of the rubber sheet 4 can be glued to the collar 13 and the support ring 5 with strong adhesive for easy installation and replacement.

[0024] To facilitate the covering of the upper part of the transparent cover 14, the upper ends of the two rubber sheets 4 are surrounded on the outer surface of the rotating rod 12, forming a hollow, trumpet-shaped structure.

[0025] An electric push rod 10 is fixedly installed on the upper end of the mounting bracket 6. The telescopic end of the lower end of the electric push rod 10 is fixedly connected to the upper end of the transparent cover 14. When the electric push rod 10 retracts during operation, it can drive the transparent cover 14, the support ring 5, and the collar 13 to move upward, thus opening the mixing drum 1.

[0026] An L-shaped sliding rod 8 is fixed to the upper end of the transparent cover 14. The mounting bracket 6 has a sliding groove 9. The end of the sliding rod 8 is vertically slidably connected inside the sliding groove 9. During the up-and-down movement of the transparent cover 14, the end of the sliding rod 8 moves up and down inside the sliding groove 9.

[0027] A discharge hopper 3 is fixed through one side of the bottom of the mixing drum 1, and a sealing plate 2 is slidably inserted into the inner wall of the upper end of the discharge hopper 3. When the mud and sand are mixed, the sealing plate 2 can be moved to disengage from the discharge hopper 3, so that the mud and sand mixture in the mixing drum 1 can flow out of the discharge hopper 3 for unloading.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: The user retracts the electric push rod 10, which moves the transparent cover 14, support ring 5, and collar 13 upwards, opening the mixing drum 1. The user then pours in the pre-mixed cement, sand, and water. The electric push rod 10 extends, causing the transparent cover 14 to descend and cover the upper part of the mixing drum 1. The motor 11 drives the rotating rod 12 and mixing blades 16 to rotate, mixing the cement and sand until the mixture is complete. To prevent cement dust from splashing out during mixing, a transparent cover 14 is installed at the upper part of the mixing drum 1. The bottom of the transparent cover 14 fits against the upper part of the mixing drum 1, covering the upper part of the mixing drum 1 and preventing excessive pollution caused by cement dust splashing during mixing, thus reducing the impact on the surrounding environment.
