Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-14This utility model discloses a material adjustment device for a concrete transport vehicle, used to adjust the slump of concrete. It is installed on the bottom plate 5 of the mixer truck 1 and includes a mixing drum 2, a feed hopper 3 and a filling box 4. The feed hopper 3 is supported on the bottom plate 5 by a support frame 6. Multiple filling boxes 4 are provided on one side of the mixing drum 2 on the bottom plate 5. The bottom surface 45 of the filling box 4 is inclined. The top surface of the filling box 4 is rectangular and horizontally arranged. The cross-section of the filling box 4 is a right trapezoid.

[0033] The cross-section of the existing concrete transport truck's floor plate 5 is as follows: Figure 6 As shown, a flat bottom recess 52 is provided in the middle, and the two sides of the bottom recess 52 are inclined surfaces 51. The bottom recess 52 is used to support the mixing drum 2. The existing stuffing box 4 is located on the bottom recess 52 below the mixing drum 2. The stuffing box 4 is rectangular in shape. Because the stuffing box 4 is located near the center of the cross section of the vehicle floor 5, the stuffing box 4 is very inconvenient to add materials.

[0034] The bottom surface 45 of the filling box 4 of this utility model is inclined, and the inclination angle of the bottom surface 45 is the same as the slope of the inclined surface 51. The filling box 4 is located on the inclined surface 51, so the top surface of the filling box 4 is horizontal. The filling box 4 is close to the outer edge of the vehicle floor 5, which greatly facilitates the feeding. The inner side of the filling box 4 abuts against the bottom support of the mixing drum 2.

[0035] The existing filling pump for the stuffing box 4 is located outside the stuffing box 4. Because the bottom of the stuffing box 4 is horizontal, there will inevitably be a lot of residual liquid at the bottom when filling. The filling pump 46 of this invention is located at the lowest end of the bottom surface 45 inside the stuffing box 4, so that the residual liquid at the bottom is minimized when filling.

[0036] A fixing plate 47 is provided at the bottom of the stuffing box 4. Figure 7 In the middle, the fixing plate 47 is visible from the water pipe inlet / outlet 42, and the liquid pump 46 is fixed on the fixing plate 47.

[0039] The feed hopper 3 is equipped with a housing 8 for housing the camera 10. The housing 8 is fixed above the internal discharge port 31 of the feed hopper 3. When it is necessary to monitor the situation inside the mixing drum 2, the controller drives the telescopic rod 85 to extend the telescopic bracket 9 out of the housing 8. The camera 10, located on the telescopic bracket 9, enters the internal discharge port 31 of the feed hopper 3, facing the inside of the mixing drum 2, thereby taking pictures of the situation inside the mixing drum 2. The images and videos are transmitted to the display screen 7 so that the staff below can understand the situation at any time. Video streams and photos or video information can also be pushed to the cloud. A supplementary light 11 is provided next to the camera 10 to supplement light in low-light conditions. The display screen 7 can be used as follows: Figure 8 As shown, it is located on support frame 6, or it can be in the cab, or on a mobile phone or computer.

[0040] The outer shell 8 is rectangular, and a telescopic bracket 9 is provided inside the shell 8. The bottom of the shell 8 has an inlet and outlet for the telescopic bracket 9. When the telescopic bracket 9 is retracted, its bottom blocks the inlet and outlet to prevent debris from entering the shell 8. Fixing ears 83 are provided on both sides of the shell 8, and fixing holes are provided on the fixing ears 83 for fastening the shell 8 to the inner wall of the feed hopper 3 with bolts. A power cord inlet 81 is provided on the inner wall of the shell 8 facing the feed hopper 3, and a water pipe inlet 82 is provided on the side of the power cord inlet 81. A corresponding through hole is provided on the inner wall of the feed hopper 3, through which the water pipe enters the shell 8. A water pipe outlet 84 is provided at the bottom of the shell 8; the water pipe outlet 84 is located on the inlet and outlet side of the telescopic bracket 9. In this way, the water pipe is fixed by the shell 8, and the water pipe faces the inside of the mixing drum 2.

[0041] The housing 8 is equipped with a telescopic rod 85 that is fixedly connected to the telescopic bracket 9. The rear of the telescopic rod 85 is connected to the front of the piston rod of the electric hydraulic cylinder (not shown in the figure), and the electric hydraulic cylinder is fixed to the rear of the housing 8.

[0042] The telescopic bracket 9 is equipped with a camera 10 and a fill light 11. Openings are provided on the front and rear sides of the telescopic bracket 9. The camera 10 facilitates image and video capture, while the fill light 11 provides illumination. The images and videos are transmitted to a display device so that staff below can monitor the situation at any time. The positions of the camera 10 and the fill light 11 are interchangeable.
