DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Refer to the instruction manual Figure 1 - Figure 5 , a concrete mixing device that is easy to clean, such as Figure 1 and Figure 2 As shown, it comprises a supporting frame 1, a stirring drum 2 is rotatably mounted on the top of the supporting frame 1, a motor 3 is arranged on one side of the stirring drum 2, a discharge port 4 is connected to one side of the stirring drum 2, and a wall scraping mechanism 5 is arranged on one side of the discharge port 4;

[0025] like Figure 3and Figure 4 As shown, the scraping mechanism 5 includes a ring 51 rotatably mounted on the outer wall of the discharge port 4, the diameter of the ring 51 is larger than the diameter of the discharge port 4, a fixed plate 52 is fixedly mounted on the bottom of the ring 51, a weight block 53 is fixedly mounted on the bottom of the fixed plate 52, the weight block 53 and the fixed plate 52 are arranged perpendicular to each other, and the weight block 53 is arranged vertically downward, so that the weight block 53 pulls the fixed plate 52 by gravity so that the ring 51 rotating on the outer wall of the discharge port 4 maintains a vertically downward stable state, and then when the discharge port 4 rotates following the stirring drum 2, the ring 51 remains stable.

[0026] like Figure 3 and Figure 4 As shown, a support rod 54 is slidably installed on one side of the fixed plate 52, and the support rod 54 is arranged in a vertical state. A fixed plate 55 is fixedly installed at the bottom of the support rod 54, and limited sliding rods 56 are fixedly installed on both sides of the fixed plate 55. The two limited sliding rods 56 are arranged vertically upward, and the two limited sliding rods 56 are slidably installed on the inner wall of the fixed plate 52, so that the fixed plate 52 drives the support rod 54 to be located at the outer wall of the discharge port 4;

[0027] like Figure 3 and Figure 4 As shown, a limit spring 57 is fixedly installed on the top of the fixed plate 55, and the limit spring 57 is fixedly installed on the bottom of the fixed plate 52. The limit spring 57 and the fixed plate 52 are arranged perpendicular to each other. Then, when the scraper 58 extends into and fits against the inner wall of the discharge port 4, the fixed plate 55 at the bottom of the support rod 54 uses the limit slide rod 56 and pulls the limit spring 57, so that the support rod 54 drives the scraper 58 to be stuck on the inner wall of the discharge port 4, and the scraper 58 is tightly fitted with the inner wall of the discharge port 4 through the limit spring 57.

[0028] like Figure 3 and Figure 4 As shown, a scraper 58 is fixedly installed on the top of the support rod 54, and the bottom of the scraper 58 is in contact with the inner wall of the discharge port 4. The scraper 58 is arranged in an inclined state, and the scraper 58 and the discharge port 4 are arranged perpendicular to each other, so that when the discharge port 4 rotates to discharge, the scraper 58 always remains vertical and scrapes the concrete on the inner wall of the discharge port 4 out;

[0029] like Figure 3 and Figure 4As shown, rotating shafts 59 are rotatably installed on both sides of the supporting rod 54, and supporting plates 510 are fixedly installed on the outer walls of the two rotating shafts 59. The two supporting plates 510 are arranged in an arc shape, and the tops of the two supporting plates 510 are flush with the inner walls of the discharge port 4. The two supporting plates 510 are arranged in a horizontal state, and the outer walls of the two supporting plates 510 are in contact with the outer walls of the discharge port 4. The concrete flowing out of the discharge port 4 squeezes the two supporting plates 510, so that the supporting plates 510 are forced to rotate into a horizontal state on both sides of the supporting rod 54 through the rotating shafts 59, thereby bringing out the concrete and preventing the concrete from falling on structures such as the fixed plate 52.

[0030] like Figure 3 and Figure 5 As shown, the outer wall of the discharge port 4 is provided with a top protection mechanism 6, and the top protection mechanism 6 includes a pull rope 61 fixedly installed on the outer walls of the two supporting plates 510, and the two pull ropes 61 are symmetrically arranged. A cover guard plate 62 is fixedly installed on the top of the two pull ropes 61, and the cover guard plate 62 is arranged in an arc shape. The cover guard plate 62 and the outer wall of the discharge port 4 are arranged corresponding to each other, and the outer wall of the cover guard plate 62 is in contact with the outer wall of the discharge port 4. The two supporting plates 510 are forced to flip horizontally and pull the pull ropes 61 on both sides, and then the pull ropes 61 pull the cover guard plate 62 down to cover the outer wall of the discharge port 4.

[0031] like Figure 3 and Figure 5 As shown, a lifting plate 63 is fixedly installed on the outer wall of the cover guard plate 62, and a telescopic rod 64 is fixedly installed on one side of the lifting plate 63. The telescopic rod 64 is fixedly installed on the top of the ring 51, and the telescopic rod 64 is arranged in a vertical state. A supporting spring 65 is fixedly installed on the bottom of the lifting plate 63, and the supporting spring 65 is fixedly installed on the top of the ring 51, so that the cover guard plate 62 moves downward to pull the lifting plate 63 to compress and the supporting spring 65 to move vertically downward, so that the cover guard plate 62 moves down to cover the outer wall edge of the discharge port 4, so as to prevent part of the concrete from leaking out from the edge outer wall of the discharge port 4 when the discharge of the discharge port 4 is not thorough.

[0032] The working process and principle of the utility model are as follows:

[0033] The weight block 53 pulls the fixed plate 52 by gravity so that the sleeve ring 51 rotating on the outer wall of the discharge port 4 maintains a vertical downward stable state, and then the fixed plate 52 drives the support rod 54 to be located at the outer wall of the discharge port 4. When the scraper 58 extends into and fits the inner wall of the discharge port 4, the fixed plate 55 at the bottom of the support rod 54 uses the limit slide rod 56 to pull the limit spring 57, so that the support rod 54 drives the scraper 58 to be stuck on the inner wall of the discharge port 4, and the scraper 58 is closely fitted with the inner wall of the discharge port 4 through the limit spring 57. When the discharge port 4 rotates to discharge materials, the scraper 58 always remains vertical and scrapes the concrete on the inner wall of the discharge port 4 out, that is, the inner wall of the discharge port 4 is scraped clean, avoiding the adhesion and clogging of the inner wall of the discharge port 4 by concrete to affect the discharge efficiency.

[0034] At the same time, the two supporting plates 510 are forced to flip horizontally and pull the pull ropes 61 on both sides, and then the pull ropes 61 pull the cover plate 62 downward, and then the cover plate 62 moves downward to pull the lifting plate 63 to compress and support the spring 65 to move vertically downward, so that the cover plate 62 moves down to cover the outer wall edge of the discharge port 4, and then when the discharge port 4 is not discharged thoroughly, part of the concrete is prevented from leaking out from the edge outer wall of the discharge port 4.
