[0022] The above scheme is adopted: the mixing barrel 1 is the shell of the mixing device used for preparing cement slurry, the operator can pour the cement slurry raw materials into the mixing barrel 1 and stir them through the composite mechanism 2, and automatically add water through the water injection mechanism 3, so as to ensure that the cement slurry components are evenly mixed under stirring, and there is no need to add water manually, which reduces the workload of the operator; through the composite mechanism 2, the cement and water can be stirred in both forward and reverse directions at the same time, so that the cement particles and water can fully move under the action of forces in different directions, ensuring that the cement slurry in all parts can be fully stirred, avoiding local unevenness, and at the same time speeding up the stirring efficiency; and during the stirring process, the inner wall of the mixing barrel 1 can be scraped by the scraper 207 to prevent the cement slurry from adhering to the inner wall of the mixing barrel 1, which is inconvenient for the operator to clean; the mixed cement slurry can be discharged through the discharge port 4, and a valve is installed on the discharge port 4, which is the existing technology. The valve is in a closed state during the stirring process, and the valve can be opened when it needs to be discharged for subsequent processing.

[0023] like Figure 2 and Figure 3 As shown, the mounting block 201 is fixedly connected to the top outer wall of the mixing barrel 1, and the rotating rod A205 is rotatably connected to the inner wall of the mounting block 201; the outer wall of the scraper 207 contacts the inner wall of the mixing barrel 1, and the secondary bevel gear B211 is rotatably connected to the outer wall of the rotating rod A205, and the secondary bevel gear A212 and the secondary bevel gear B211 are both engaged with the main bevel gear 204.

[0024] The above scheme is adopted: the motor 202 is started, and its output shaft drives the rotating rod A205 to rotate, and the connecting rod 206 and the scraper 207 provided on the outer wall of the rotating rod A205 rotate accordingly, and the stirring rod A208 rotates with the scraper 207 to stir the cement and water, and the scraper 207 can continuously scrape the cement attached to the inner wall of the mixing barrel 1; when the rotating rod A205 rotates, the secondary bevel gear A212 rotates accordingly, driving the main bevel gear 204 meshing with it to rotate, while the rotating shaft 203 is in a fixed state; when When the main bevel gear 204 rotates, it drives the auxiliary bevel gear B211 meshing with it below to rotate, and the auxiliary bevel gear B211 and the auxiliary bevel gear A212 are symmetrically distributed, so that the two rotate in opposite directions. The auxiliary bevel gear B211 drives the rotating rod B209 to rotate, and the stirring rod B210 set on the outer wall of the rotating rod B209 can stir the cement and water. Therefore, by the stirring rod B210 and the stirring rod A208 rotating in opposite directions at the same time, the cement slurry can be stirred more evenly and the stirring efficiency can be improved.

[0025] like Figure 4As shown, the water injection mechanism 3 includes a connecting block 301, the outer wall of the connecting block 301 is fixedly connected to the water tank 302, the bottom outer wall of the water tank 302 is elastically connected to the movable plate 304 through a connecting spring 303, the outer wall of the movable plate 304 is fixedly connected to the protrusion 305, the top outer wall of the protrusion 305 is fixedly connected to the counterweight ball 306, and the outer wall of the rotating rod B209 is fixedly connected to the baffle 307.

[0026] The above scheme is adopted: water can be automatically added to the inside of the mixing barrel 1 through the water injection mechanism 3 during the mixing process, so that the operator does not need to add water manually, reducing the operator's workload; the protrusion 305 is hemispherical, and its arc surface faces downward; an opening is provided on the outer wall of the bottom end of the water tank 302, and the diameter of the counterweight ball 306 is larger than the diameter of the opening. A water inlet pipe is provided on the outer wall of the top end of the water tank 302, and the water inlet pipe is connected to an external device, which is a prior art. The external device can transport water to the water tank 302 through a water pump to add water during the mixing process.

[0027] like Figure 4 As shown, the connecting block 301 is fixedly connected to the top outer wall of the mixing barrel 1, and the counterweight ball 306 contacts the inner wall of the water tank 302; one end of the connecting spring 303 is fixedly connected to the outer wall of the movable plate 304, and the other end of the connecting spring 303 is fixedly connected to the bottom outer wall of the water tank 302; the movable plate 304 is slidably connected to the bottom outer wall of the water tank 302, and the protrusion 305 contacts the baffle 307.

[0028] The above solution is adopted: under the condition that no external force is affected, the connecting spring 303 drives the movable plate 304 and the protrusion 305 to remain in the downward state due to its own elastic force, and the counterweight ball 306 contacts the inner wall of the opening to close the opening, so that the water in the water tank 302 does not flow out; when the rotating rod B209 rotates, it drives the baffle 307 set on its outer wall to rotate. When the baffle 307 rotates to contact the arc surface of the protrusion 305, it squeezes the protrusion 305 and makes it move upward. The movable plate 304 moves accordingly to squeeze the connecting spring 303, causing it to contract under force, and the protrusion 305 05 drives the counterweight ball 306 to move upward, and the counterweight ball 306 is out of contact with the opening below the water tank 302, and the water in the water tank 302 can flow into the mixing barrel 1 from the opening; when the baffle 307 rotates to disengage from the protrusion 305, under the elastic force of the connecting spring 303, the movable plate 304, the protrusion 305 and the counterweight ball 306 move downward at the same time, closing the opening, and stopping water injection. The rotating rod B209 is continuously rotated to automatically inject water into the mixing barrel 1, and there is no need to manually add water during the mixing process, which is more convenient and reduces work intensity.

[0029] The working principle and use process of this utility model:

[0030] The mixing barrel 1 serves as the shell of the mixing device for preparing cement slurry. The operator can pour the cement slurry raw materials into it and start the motor 202. The output shaft of the motor 202 drives the rotating rod A205 to rotate. While the rotating rod A205 rotates, the connecting rod 206 and the scraper 207 arranged on its outer wall rotate accordingly. On the one hand, the scraper 207 continuously scrapes the inner wall of the mixing barrel 1 to prevent the cement slurry from adhering to the inner wall, which makes it inconvenient to clean up later. On the other hand, the stirring rod A208 rotates with the scraper 207 to stir the cement and water.

[0031] When the rotating rod A205 rotates, the secondary bevel gear A212 rotates accordingly, driving the main bevel gear 204 meshing with it to rotate. When the main bevel gear 204 rotates, it drives the secondary bevel gear B211 meshing with it below to rotate. Since the secondary bevel gear B211 and the secondary bevel gear A212 are symmetrically distributed, their rotation directions are opposite. The secondary bevel gear B211 drives the rotating rod B209 to rotate, and the stirring rod B210 set on the outer wall of the rotating rod B209 also stirs the cement and water. By rotating the stirring rod B210 and the stirring rod A208 in opposite directions at the same time, the cement slurry is stirred more evenly, and the stirring efficiency is improved, avoiding the problem of cement slurry agglomeration caused by stirring in the same direction for a long time.

[0032] At the same time, the rotation of the rotating rod B209 drives the baffle 307 on its outer wall to rotate. When the baffle 307 rotates to contact the arc surface of the protrusion 305, the protrusion 305 is squeezed to move upward, and the movable plate 304 moves accordingly, squeezing the connecting spring 303 to cause it to contract under force. The protrusion 305 drives the counterweight ball 306 to move upward, and the counterweight ball 306 is out of contact with the opening below the water tank 302. The water in the water tank 302 can flow into the mixing barrel 1 from the opening. When the baffle 307 rotates to disengage from the protrusion 305, the elastic force of the connecting spring 303 drives the protrusion 305, the movable plate 304 and the counterweight ball 306 to move downward, thereby closing the opening. As a result, the rotating rod B209 continuously rotates, and water can be automatically added to the mixing barrel 1. There is no need to manually add water during the mixing process, which reduces the workload of the operator.
