[0019] like Figure 1 , Figure 2As shown, a hopper for a concrete mixer includes a housing 1. The housing 1 contains a grinding chamber 101 and a collection chamber 102, with the collection chamber 102 located to the left of the grinding chamber 101. The grinding chamber 101 has an inlet 104 and a outlet 105 on its upper and lower sides, respectively. A first grinding roller 3 and a second grinding roller 4 are disposed within the grinding chamber 101. The second grinding roller 4 is rotatably and sealed within the grinding chamber 101 via a sealed bearing. Cavities are formed in both the front and rear side walls of the grinding chamber 101. Baffles 13 are slidably connected to these cavities via grooves and sliders. The housing 1 also has openings on its front and rear sides that connect to the cavities. The sliding groove is connected to the cavity. The baffle 13 always closes the side of the sliding groove. The two ends of the first grinding roller 3 are rotatably connected to the two baffles 13 through bearings. Both ends of the first grinding roller 3 are located in the sliding groove. Two sliding plates 14 and two first electric telescopic rods 2 are symmetrically arranged on the front and rear sides of the housing 1. The sliding plates 14 are slidably connected to the front and rear sides of the housing 1 through the slide rail. The side of the sliding plate 14 away from the housing 1 is bolted with a connecting plate 15 connected to the output shaft of the first electric telescopic rod 2. Both ends of the first grinding roller 3 pass through the baffle 13 and are rotatably connected to the sliding plate 14 through bearings.

[0020] The housing 1 and the sliding plate 14 are provided with a drive assembly for driving the second grinding roller 4 and the first grinding roller 3 to rotate.

[0021] During use, the operator pours concrete material into the grinding chamber 101 through the feed inlet 104. At the same time, the drive component drives the first grinding roller 3 and the second grinding roller 4 to rotate, thereby grinding the concrete material entering the grinding chamber 101, improving the fineness of the concrete material, and thus improving the quality of the concrete. When the operator needs to adjust the grinding fineness of the concrete powder, the operator can push the first grinding roller 3 to move left and right along the sliding groove through the first electric telescopic rod 2, thereby adjusting the distance between the first grinding roller 3 and the second grinding roller 4, thereby adjusting the grinding fineness of the concrete powder. When adjusting the position of the first grinding roller 3, the baffle 13 always closes the sliding groove to prevent the concrete powder in the grinding chamber 101 from flying out, reducing the waste of concrete powder.

[0022] In this embodiment, the drive assembly includes a first rotary motor 16 bolted to one of the sliding plates 14 and a second rotary motor 17 bolted to the rear side of the housing 1. The output shaft of the first rotary motor 16 passes through the sliding plate 14 and is connected to the end of the first grinding roller 3. The output shaft of the second rotary motor 17 passes through the housing 1 and is connected to the end of the second grinding roller 4. In use, the first rotary motor 16 and the second rotary motor 17 can drive the first grinding roller 3 and the second grinding roller 4 to rotate in opposite directions, thereby grinding the concrete powder passing between the first grinding roller 3 and the second grinding roller 4, thereby improving the fineness of the concrete powder.

[0023] In this embodiment, a filter screen 5 located on the first grinding roller 3 and below the first grinding roller 3 is installed in the grinding chamber 101 by bolts. The filter screen 5 is inclined upward from left to right. A collection component for collecting the material on the upper side of the filter screen 5 is provided in the collection chamber 102. When in use, the filter screen 5 can filter the ground concrete powder, further improving the quality of the concrete powder.

[0024] Preferably, the staff can replace the filter screen 5 according to the required fineness of the concrete powder.

[0025] In this embodiment, a feed port 103 is provided between the collection chamber 102 and the grinding chamber 101, and the lower side of the feed port 103 and the upper side of the filter screen 5 are located on the same plane.

[0026] In this embodiment, the collection assembly includes a second electric telescopic rod 11 bolted to the right side of the collection cavity 102, a sealing plate 12 slidably connected to the right side of the collection cavity 102 via a slide rail, a collection box 9 slidably connected to the lower side of the collection cavity 102 via a slider and a slide groove, and a second guide platform 8 bolted into the collection cavity 102. The left side of the collection box 9 and the left side of the housing 1 are on the same vertical plane. The output shaft of the second electric telescopic rod 11 is connected to the upper side of the sealing plate 12, and the second telescopic rod can push the sealing plate 12 to close the feed port 103. The right side of the collection cavity 102 contacts the left side of the guide platform, and the upper side of the guide platform is downward from right to left. The collection box 9 is tilted, and a handle 10 is bolted to its left side. During use, the concrete powder on the upper side of the filter screen 5 accumulates on the left side of the filter screen 5 under the action of gravity. When the staff needs to clean and collect the material, the staff controls the second electric telescopic rod 11 to move the sealing plate 12 upward, so that the material outlet 103 is connected to the collection chamber 102. Then, under the action of gravity, the powder on the upper side of the filter screen 5 slides down and falls to the upper side of the second guide platform 8. The material falling to the upper side of the second guide platform 8 can slide down the second guide platform 8 into the collection box 9. Finally, the staff can pull the handle 10 to pull out the collection box 9, which makes it easier for the staff to collect the concrete powder and reduce waste.

[0027] Preferably, a vibrating motor connected to the filter screen 5 is installed inside the grinding chamber. The vibrating motor can drive the filter screen 5 to vibrate and screen, thereby ensuring screening.

[0028] In this embodiment, a first guide platform 7 located below the filter screen 5 is installed in the grinding chamber 101 by bolts. The upper side of the first guide platform 7 is inclined downward from left to right. During use, the concrete powder filtered by the filter screen 5 will fall to the side of the first guide platform 7 and slide down the upper side of the first guide platform 7 into the discharge port 105, preventing the concrete powder from accumulating in the grinding chamber 101.

[0029] In this embodiment, a feed hopper 6 is bolted to the upper side of the housing 1. The inside of the feed hopper 6 is connected to the feed port 104. During use, the operator can pour concrete powder into the grinding chamber 101 through the feed hopper 6, which improves the convenience of the operator when pouring concrete powder.
