A scraper 63 is fixedly connected to the rotating shaft 62. The lower surface of the scraper 63 contacts the inner bottom wall of the barrel body 1. The prepared raw materials and solvent are put into the barrel body 1 through the barrel mouth of the barrel body 1, and then the round block 9 is stuck into the barrel body 1, so that the barrel body 1 is connected with the barrel cover 2, and then the motor 3 is started, and the output shaft of the motor 3 drives the stirring shaft 4 to rotate. The paint is then driven to move, thereby driving the stirring blade 5 to stir and mix the raw materials and the solvent, and the prepared paint falls through the discharge chute 61. After falling, the rotating shaft 62 can be rotated to drive the scraper 63 to rotate, and the paint remaining on the bottom wall of the barrel body 1 is cleaned up, so that it falls from the discharge chute 61, thereby avoiding the situation that many existing stirring barrels are usually discharged from the discharge port under the action of gravity when discharging the stirred paint, and more paint will remain on the bottom wall of the barrel, resulting in a waste of paint. A rectangular block 65 is fixedly connected, and an annular groove 64 is provided on the barrel body 1. The annular groove 64 is slidably connected to the rectangular block 65. The rectangular block 65 slides in the annular groove 64 to make the rotation of the scraper 63 more stable. A slideway 66 is fixedly connected to the outer bottom wall of the barrel body 1. The slideway 66 is located below the discharge chute 61. A U-shaped groove 67 is provided on the barrel body 1. A baffle 68 is slidably connected in the U-shaped groove 67. When discharging is required, the baffle 68 can be slid outward to keep the baffle 68 away from the limit of the U-shaped groove 67, and the material can be discharged from the discharge chute 61. The fallen paint will fall onto the slide 66, which is convenient for the staff to take it. After the discharge is completed or during the mixing process, the baffle 68 can be slid so that the baffle 68 blocks the discharge trough 61 to prevent the paint from falling. Two springs 69 are fixedly connected to the baffle 68, and one end of the spring 69 is fixedly connected to the barrel body 1.

A cleaning plate 72 is fixedly connected to the L-shaped column 71. The cleaning plate 72 contacts the inner wall of the barrel body 1. When the L-shaped column 71 rotates, it will drive the cleaning plate 72 to scrape and clean the inner wall of the barrel body 1 to prevent the paint from adhering to the inner wall of the barrel body 1, causing the paint to be wasted. The stirring shaft A circular groove 73 is provided at one end of 4, and the circular groove 73 is adapted to the size of the rotating shaft 62. When connecting the barrel body 1 and the barrel cover 2, the circular groove 73 and the rotating shaft 62 can be connected.

A connecting groove 75 is provided on the rotating shaft 62, and a connecting block 74 is fixedly connected to the circular groove 73. The size of the connecting block 74 is adapted to the connecting groove 75. When connecting the rotating shaft 62 and the circular groove 73, the connecting block 74 can be inserted into the connecting groove 75, so that the connection between the stirring shaft 4 and the rotating shaft 62 is more stable.

[0031] Working principle: During the preparation of polyurethane waterproof coating, various raw materials and several solvents need to be mixed together, and a stirring barrel is needed to stir and mix different raw materials to accelerate the reaction between the raw materials and improve production efficiency. The prepared raw materials and solvents are put into the barrel body 1 through the barrel mouth, and then the round block 9 is inserted into the barrel body 1, so that the barrel body 1 is connected with the barrel cover 2, and then the motor 3 is started, and the output shaft of the motor 3 drives the stirring shaft 4 to rotate, thereby driving the stirring blade 5 to stir and mix the raw materials and the solvent, and the prepared coating passes through the discharge trough 61. After the paint falls, the rotating shaft 62 can be rotated to drive the scraper 63 to rotate, and the paint remaining on the bottom wall of the barrel body 1 can be cleaned up, so that it all falls from the discharge groove 61, thereby avoiding the situation that when many existing mixing barrels discharge the stirred paint, the paint is usually discharged from the discharge port by itself under the action of gravity, and a lot of paint will remain on the bottom wall of the barrel, causing waste of paint. The limited sliding of the rectangular block 65 in the annular groove 64 can make the rotation of the scraper 63 more stable. When discharging is required, the baffle 68 can be slid outward to keep the baffle 68 away from the The U-shaped groove 67 is limited, and the paint falling from the discharge groove 61 will fall onto the slide 66, which is convenient for the staff to take. After the discharge is completed or during the mixing process, the baffle 68 can be slid so that the baffle 68 blocks the discharge groove 61 to prevent the paint from falling. When the baffle 68 is pulled outward, the spring 69 is in a stretched state. Therefore, when the discharge is completed, the baffle 68 is released, and the baffle 68 is stuck in the U-shaped groove 67 under the action of the rebound elastic force of the two springs 69, making the operation more convenient. When the motor 3 drives the stirring shaft 4 to rotate, it will drive the L-shaped column 71 to rotate, and further Stirring can enhance the mixing effect of the raw materials and the solvent. When the L-shaped column 71 rotates, it will drive the cleaning plate 72 to scrape and clean the inner wall of the barrel body 1 to prevent paint from adhering to the inner wall of the barrel body 1 and causing paint waste. When connecting the barrel body 1 and the barrel cover 2, the circular groove 73 and the rotating shaft 62 can be connected, so when the stirring shaft 4 rotates, the rotating shaft 62 will be driven to rotate, further improving the convenience of operation. When connecting the rotating shaft 62 and the circular groove 73, the connecting block 74 can be inserted into the connecting groove 75, so that the connection between the stirring shaft 4 and the rotating shaft 62 is more stable.
