[0002] A concrete mixer truck is a special truck used to transport concrete for construction. Due to its appearance, it is often called a snail truck. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete. During the transportation process, the mixing drum is always kept rotating to ensure that the concrete being transported does not solidify. After the concrete is transported, the inside of the mixing drum is usually rinsed with water to prevent the hardened concrete from taking up space and reducing the volume of the mixing drum.

[0003] However, when the concrete mixer truck is flushed, the concrete attached to the inner wall of the mixing tank is washed away under the action of water pressure. However, the concrete deep in the mixing tank is difficult to be flushed by the cleaning water, resulting in a relatively mediocre effect of removing concrete waste. Utility Model Content

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application discloses a concrete waste scraping device for a concrete mixer truck. Figure 1 and Figure 2 The concrete waste scraping device of the concrete mixer truck includes a mounting rod 1, the length direction of the mounting rod 1 is parallel to the axial direction of the body, a support rod 2 is hingedly arranged on the mounting rod 1, the hinge axis of the support rod 2 is perpendicular to the length direction of the mounting rod 1, a scraper 3 is hingedly arranged at the end of the support rod 2, the rotation axis of the scraper 3 is parallel to the rotation axis of the support rod 2, the scraper 3 is used to abut against the inner wall of the mixer truck 4 and is located between the spiral stirring plates 5; it also includes a mounting frame 6, the mounting frame 6 is located outside the mixer truck 4, the mounting rod 1 is rotatably arranged on the mounting frame 6, and the rotation of the mounting rod 1 drives the scraper 3 to slide along the inner wall of the mixer truck 4.

[0023] When scraping the concrete inside the mixer truck 4, the mounting rod 1 is moved into the tank body of the mixer truck 4. After the mounting rod 1 enters the tank body, the support rod 2 and the scraper 3 rotate, so that the scraper 3 abuts against the inner wall of the tank truck and is located between the spiral stirring plates 5. Then the mounting rod 1 is rotated, and the rotation of the mounting rod 1 drives the scraper 3 to rotate. The rotation of the scraper 3 scrapes the concrete on the inner wall of the tank body, thereby improving the concrete scraping efficiency; further, the scraper 3 and the support rod 2 are both hingedly arranged, so that when the mounting rod 1 rotates, the scraper 3 passively adjusts the angle and position, and is convenient for scraping the concrete between the spiral scrapers 3.

[0024] Reference Figure 3 and Figure 4 In order to facilitate the scraper 3 to abut against the inner wall of the tank body, the support rod 2 includes a sleeve 21 hingedly arranged on the mounting rod 1 and a slide rod 22 slidably sleeved in the sleeve 21. The scraper 3 is hinged at the end of the slide rod 22. A spring 7 is arranged in the sleeve 21. One end of the spring 7 is fixedly arranged at the bottom of the sleeve 21, and the other end is fixedly arranged at the bottom of the slide rod 22. After the mounting rod 1 is moved into the tank body and the support rod 2 is located between adjacent spiral stirring screws, the scraper 3 is driven to slide toward the inner wall of the tank body under the action of the spring 7, and the scraper 3 abuts against the inner wall of the tank body, thereby facilitating the scraping of concrete on the inner wall of the tank body.

[0025] Reference Figure 3 In order to facilitate the scraper 3 to fit against the inner wall of the tank body, a first mounting shaft 8 is rotatably provided at the end of the slide rod 22, and the scraper 3 is fixedly provided on the first mounting shaft 8. A first torsion spring 9 is sleeved on the first mounting shaft 8. One side of the first torsion spring 9 is fixedly provided on the first mounting shaft 8, and the other side is fixedly provided on the slide rod 22. The torsion spring drives the scraper 3 to have a movement tendency to rotate away from the support rod 2; under the action of the first torsion spring 9, the scraper 3 is driven to rotate in a direction close to the horizontal direction, so that after the mounting rod 1 is moved into the tank body, the scraper 3 is driven by the spring 7 to abut against the inner wall of the tank body.

[0026] Reference Figure 3 Furthermore, in order to facilitate the vertical rotation of the support rod 2 after the mounting rod 1 enters the tank body, a second mounting shaft 10 is rotatably provided on the mounting rod 1, a sleeve 21 is fixedly provided on the second mounting shaft 10, and two second torsion springs 11 are sleeved on the second mounting shaft 10. The rotation directions of the two second torsion springs 11 are opposite, one side of the second torsion spring 11 is fixedly provided on the sleeve 21, and the other side is fixedly provided on the mounting rod 1, and the second torsion spring 11 drives the sleeve 21 to be in a length direction perpendicular to the mounting rod 1; after the mounting rod 1 drives the support rod 2 to enter the tank body, under the action of the second torsion spring 11, the support rod 2 is driven to rotate in the vertical direction, thereby causing the scraper 3 to rotate toward the inner wall of the tank body.

[0027] Reference Figure 4 Under the action of the first torsion spring 9 and the second torsion spring 11, it is difficult for the support rod 2 to enter the tank body. Therefore, in the embodiment of the present application, a traction rope 12 is fixedly arranged on the outer wall of the sleeve 21, and the traction rope 12 enters the mounting rod 1 and moves out through the end of the mounting rod 1; when the support rod 2 moves into the tank body, the traction rope 12 is pulled, and the traction rope 12 drives the support rod 2 to rotate in the direction close to the mounting rod 1. When the scraper 3 contacts the mounting rod 1, the scraper 3 rotates in a direction close to parallel to the mounting rod 1, so that the support rod 2 and the scraper 3 are close to the mounting rod 1, which facilitates the mounting rod 1, the support rod 2 and the scraper 3 to enter the tank body.

[0028] Reference Figure 4 In order to facilitate the removal of concrete from the side wall of the spiral stirring plate 5, the sleeve 21, the slide rod 22 and the mounting rod 1 are all hollow, and the ends away from each other are closed. The sleeve 21 is connected to the mounting rod 1, and the mounting rod 1 is connected to an external water source. A water spray hole 13 is provided on the sleeve 21 and the slide rod 22, and the water spray hole 13 faces the spiral stirring plate 5; the cleaning water is injected into the mounting rod 1, and the cleaning water in the mounting rod 1 enters the sleeve 21 and the slide rod 22, and is sprayed out from the water spray hole 13. After the cleaning water is sprayed, the side of the spiral stirring plate 5 is rinsed, and the operation is simple and convenient.

[0029] Reference Figure 4In order to improve the cleaning effect of the cleaning water, a water spray pipe is embedded in the water spray hole 13, and the water spray pipe is flat-mouthed and vertical; the water outlet of the water spray pipe is flat-mouthed, which increases the range of spraying cleaning water, and when the mounting rod 1 rotates, it is convenient to change the flushing position.

[0030] Reference Figure 4 In order to reduce the leakage of cleaning water through the opening of the sleeve 21, a bellows 14 is arranged in the sleeve 21, the bellows 14 is connected to the mounting rod 1, the other end of the bellows 14 is located in the slide rod 22 and is sealed, and a plurality of water outlet holes are opened on the bellows 14; the cleaning water in the mounting rod 1 enters the bellows 14 and is transferred from the bellows 14 to the slide rod 22, thereby reducing the leakage of cleaning water.

[0031] The implementation principle of a concrete waste scraping device for a concrete mixer truck in the present application is as follows:

[0032] When scraping the concrete inside the mixer truck 4, the mounting rod 1 is moved into the tank body of the mixer truck 4. After the mounting rod 1 enters the tank body, the support rod 2 and the scraper 3 rotate, so that the scraper 3 abuts against the inner wall of the tank truck and is located between the spiral stirring plates 5. Then the mounting rod 1 is rotated, and the rotation of the mounting rod 1 drives the scraper 3 to rotate. The rotation of the scraper 3 scrapes the concrete on the inner wall of the tank body, thereby improving the concrete scraping efficiency; further, the scraper 3 and the support rod 2 are both hingedly arranged, so that when the mounting rod 1 rotates, the scraper 3 passively adjusts the angle and position, and is convenient for scraping the concrete between the spiral scrapers 3.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
