[0034] like Figure 1-3 As shown, the coarse aggregate filtration device for the concrete truck discharge chute includes:

[0035] Filter assembly 4 is fixedly installed on the top side surface of the bottom end of the base plate 2. An outlet shell 5 is installed on the front side of the filter assembly 4. The filter assembly 4 is used to intercept coarse aggregate in mortar.

[0036] The fixing mechanism 6 is installed on the top of the adjusting mechanism 3 and is fixedly connected to the end surface of the discharge shell 1.

[0037] The adjustable mechanism 3 allows for easy adjustment of the position of the clamp 62 according to the size of the outlet shell 1. The clamp 62 is fixedly connected to the side edge of the outlet shell 1 by the fixing bolts 63, thus fixing the clamp 62 in place. This ensures that the fixing mechanism 6 is stably fixed at the end of the outlet shell 1, and the entire filter device is stably installed at the end of the outlet shell 1. The filter screen 42 intercepts coarse aggregate in the concrete, reducing the impact of coarse aggregate on the uniformity of the concrete, avoiding the need for secondary manual screening, and improving construction efficiency. During the movement of the adjusting fixing mechanism 6, the guide seat 71 moves along the guide column 72. The movement of the guide seat 71 along the guide column 72 is limited, improving the stability of the movement of the fixing mechanism 6 and ensuring that the baffle 65 fits tightly against the rear side of the filter screen 42, facilitating the subsequent filtration of coarse aggregate in the concrete.

[0038] The adjustment mechanism 3 includes a threaded post 32, a handle, a movable seat 33, and a movable groove 34. The movable groove 34 is engaged with the top side surface of the base plate 2. The movable seat 33 is slidably connected in the movable groove 34. The threaded post 32 is installed in the movable groove 34. The handle is fixedly connected to the left end of the threaded post 32. The movable seat 33 is threadedly sleeved on the surface of the threaded post 32.

[0039] According to the size of the discharge shell 1, rotate the handle. The handle drives the fixed threaded column 32 to rotate. The threaded column 32 drives the movable seat 33 with the surface threaded sleeve. The movable seat 33 drives the clamping shell 62 on the top side of the clamping plate 61 to move. Adjust the position of the two clamping shells 62 and slide them into the two sides of the discharge shell 1. After adjusting the position of the clamping shells 62, rotate the fixing bolt 63 to fix the clamping shells 62 to the side edge of the discharge shell 1, so as to fix the clamping shells 62 in place and make it easy to clamp and fix them according to the size of the end of the discharge shell 1.

[0040] There are two movable seats 33, and the threaded connection directions of the two movable seats 33 and the threaded post 32 are opposite.

[0041] The filter assembly 4 includes a filter frame 41, a filter screen 42, and a limiting plate 43. The filter frame 41 is fixedly connected to the top side of the bottom end, and the filter screen 42 is fixedly connected inside the filter frame 41. The limiting plate 43 is provided on the front side of the filter screen 42.

[0042] During concrete discharge, coarse aggregates in the concrete are intercepted by the filter screen 42, which reduces the impact of coarse aggregates on the uniformity of the concrete, avoids the need for secondary manual screening, and improves construction efficiency.

[0043] The number of limiting plates 43 is several, and the several limiting plates 43 are equidistantly distributed on the front side of the filter frame 41. The limiting plates 43 are fixedly connected to the front side of the filter frame 41.

[0044] The fixing mechanism 6 includes a clamping plate 61, a clamping shell 62, fixing bolts 63, and a limiting seat 64. The clamping plate 61 is fixedly connected to the top surface of the movable seat 33. The clamping shell 62 is fixedly connected to the top side of the clamping plate 61. The fixing bolts 63 are provided on the outer side of the clamping shell 62. The limiting seat 64 is fixedly connected to the front end of the clamping shell 62. A baffle 65 is fixedly connected to the front side of the clamping plate 61.

[0045] A rubber pad 66 is fixedly connected to the inner wall of the clamping plate 61, and the rubber pad 66 is in close contact with the outer surface of the discharge shell 1.

[0046] There are two baffles 65. The bottom side of the baffle 65 is slidably connected to the top side of the bottom plate 2, and the front side of the baffle 65 is slidably connected to the rear surface of the filter screen 42.

[0047] A guide mechanism 7 is fixedly installed on the front side of the baffle 65. The guide mechanism 7 includes a guide seat 71, a guide post 72, and a mounting seat 73. The guide seat 71 is fixedly connected to the front side of the baffle 65. The guide seat 71 is slidably connected in the guide groove on the top side surface of the filter frame 41. The guide post 72 slides through the side surface of the guide seat 71. The mounting seat 73 is fixedly connected to the end of the guide post 72.

[0048] During the adjustment of the fixed mechanism 6, the guide seat 71 moves along the guide column 72. The movement of the guide seat 71 along the guide column 72 is limited, which improves the stability of the fixed mechanism 6 and ensures that the baffle 65 fits tightly against the back of the filter screen 42, which facilitates the subsequent filtration of coarse aggregate in the concrete.

[0049] The guide seat 71 has a T-shaped cross-section. There are two guide seats 71. Both guide seats 71 are slidably connected to the surface of the guide post 72. The guide seats 71 fixedly connected to the two ends of the guide post 72 are fixedly connected to the front side of the filter frame 41.

[0050] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
