[0002] Drainage pipes are mainly responsible for draining rainwater, sewage, farmland irrigation and other drainage tasks. Drainage pipes are divided into plastic drainage pipes, concrete drainage pipes and reinforced concrete drainage pipes. Reinforced concrete drainage pipes, as the name suggests, are made of a combination of steel bars and concrete. During the preparation process of concrete, cement, sand and gravel and water need to be mixed and stirred.

[0003] In the prior art, when preparing concrete for producing drainage pipes, the operator puts sand and gravel and cement into a mixing frame respectively, and then adds water to mix them. However, the sand and gravel generally contain many larger stones. After the concrete made by mixing these larger stones is made into drainage pipes, the larger stones are on the outer surface of the drainage pipes, which will cause the surface flatness of the drainage pipes to be poor and the produced drainage pipes to be poor in appearance. In addition, when the sand and gravel are mixed with the cement, the sand and gravel are on two different levels. During mixing, it is difficult to quickly mix the sand and gravel and cement. For this reason, we have designed a reinforced concrete drainage pipe raw material pretreatment device to solve the above problems. Utility Model Content

[0024] A cleaning mechanism is provided between the two first baffles 8, the bottom of the cleaning mechanism abuts against the top of the screen frame 7, and the cleaning mechanism includes a push plate 18 slidably connected between the two first baffles 8, a second baffle 17 is fixedly installed on the top of the push plate 18, a connecting rod 16 is fixedly installed on the side wall of the second baffle 17, and a rectangular frame 13 is fixedly installed on the side wall of the connecting rod 16;

[0025] The bottom of the mounting plate 19 is rotatably connected with a stirring rod 10, and a second transmission wheel 20 coaxially rotating therewith is fixedly mounted on the stirring rod 10. A driving mechanism is provided between the mounting frame 4 and the top of the mounting plate 19, and the driving mechanism extends into the cleaning mechanism and is slidably connected thereto. The driving mechanism includes a conveyor belt 11 installed between the mounting frame 4 and the top of the mounting plate 19, and a driving rod 12 is fixedly mounted on the top of the conveyor belt 11, and the driving rod 12 extends into the rectangular frame 13 and is slidably connected thereto. By setting the driving mechanism, the driving mechanism and the cleaning mechanism, it can ensure that sand and cement can be added to the frame 1 in small amounts during mixing, so as to facilitate rapid mixing thereof.

[0026] A driving mechanism is provided on the side wall of the mounting frame 4, and the output shaft end of the driving mechanism is fixedly connected to the rotating shaft of the driving mechanism, and the driving mechanism is connected to the second transmission wheel 20. The driving mechanism includes a driving motor 5 fixedly installed on the side wall of the mounting frame 4, and a first transmission wheel 14 is fixedly installed on the output shaft of the driving motor 5. A transmission belt 15 is connected between the first transmission wheel 14 and the second transmission wheel 20, and the output shaft end of the driving motor 5 is fixedly connected to the rotating shaft of the conveyor belt 11. Through the arrangement of the screen frame 7, the first baffle 8, the vibration mechanism, the driving mechanism, the driving mechanism and the cleaning mechanism, when the sand and cement are stirred and mixed, the larger sand and gravel can be cleaned out to ensure the beauty of the drainage pipes produced subsequently.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] When concrete preparation is needed, first, the operator puts sand and gravel into the left feed hopper 2, and cement into the right feed hopper 2, and starts the drive motor 5 and the vibration motor 6. The vibration motor 6 drives the screen frame 7 on the first baffle 8 to vibrate slightly left and right through the T-shaped plate 9, and the drive motor 5 drives the conveyor belt 11 and the first transmission wheel 14 to rotate clockwise, and the first transmission wheel 14 drives the stirring rod 10 on the second transmission wheel 20 to rotate through the transmission belt 15. The sand and gravel in the left feed hopper 2 falls onto the screen frame 7, and the shaking screen frame 7 screens it. The larger sand and gravel stays on the screen frame 7, and the smaller sand and gravel falls into the frame body 1 through the screen frame 7. When the conveyor belt 11 rotates, it drives the driving rod 12 to rotate clockwise, and the driving rod 12 squeezes the rectangular frame 13 to move to the left, and the rectangular frame 13 drives the push plate 18 on the second baffle 17 to move to the left through the connecting rod 16. The plate 18 pushes the larger sand and gravel to the left. When the second baffle 17 blocks the feed hopper 2 on the left, the second baffle 17 is separated from the blockage of the feed hopper 2 on the right, and the push plate 18 continues to push the sand and gravel to move to the left. At this time, the cement in the feed hopper 2 on the right falls into the frame 1, and the stirring rod 10 rotates to stir the sand and gravel and cement. When the second baffle 17 moves to the leftmost end, the second baffle 17 pushes the sand and gravel down. When the driving rod 12 rotates to the upper right and moves to the right, it drives the push plate 18 to move to the right, and the push plate 18 drives the second baffle 17 to move to the right. At this time, the second baffle 17 is separated from the blockage of the feed hopper 2 on the left, and blocks the feed hopper 2 on the right. The sand and gravel in the feed hopper 2 on the left falls down for screening again, and so on and so forth, to achieve the screening and stirring and mixing of sand and gravel. During the stirring process, the operator introduces water into the water inlet pipe 3 to mix the sand, gravel, cement and water.
