[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Please also refer to Figures 1 to 5 , a discharge hopper assembly for a mixing station provided by the present invention is now described. The discharge hopper assembly for a mixing station includes a discharge hopper body 1, which is a conical structure; the top of the discharge hopper body 1 is a large end, and is detachably connected to the mounting frame of the mixing station; the top of the discharge hopper body 1 is a feed port; the bottom of the discharge hopper body 1 is a small end, and the small end of the discharge hopper body 1 is provided with an opening and closing valve, which is a prior art and will not be described in detail here. Among them, a plurality of strip-shaped wear-resistant lining plates 2 are provided on each inner side wall of the discharge hopper body 1, and each strip-shaped wear-resistant lining plate 2 is slidably matched with the discharge hopper body 1; a fixed structure is provided between the strip-shaped wear-resistant lining plate 2 and the discharge hopper body 1, and the fixed structure can laterally limit the position of the strip-shaped wear-resistant lining plate 2.

[0026] The utility model provides a discharge hopper assembly for a mixing station. Compared with the prior art, when it is necessary to remove the strip wear-resistant lining 2, the strip wear-resistant lining 2 is slid upward along the side wall of the discharge hopper body 1. When the strip wear-resistant lining 2 is separated from the fixed structure, the strip wear-resistant lining 2 can be removed from the discharge hopper body 1; through the above-mentioned arrangement of the present application, the fixed structure can play a role in lateral limitation of the strip wear-resistant lining 2, so the strip wear-resistant lining 2 will not be separated from the inner side wall of the discharge hopper; and compared with the bolt connection method in the prior art, the above-mentioned connection method of the present application is easier to disassemble.

[0027] For example, a connecting frame 11 is fixedly provided on the top of the discharge hopper body 1, and a plurality of connecting holes 12 are provided on the connecting frame 11 along its circumference; through the above-mentioned setting method, it is convenient to fix the discharge hopper body 1 on the mounting frame of the mixing station; when the strip wear-resistant lining 2 in the discharge hopper body 1 needs to be replaced, the discharge hopper body 1 is first removed from the mounting frame, and then the strip wear-resistant lining 2 is removed.

[0028] It should be noted that by arranging the wear-resistant liner into a strip structure, compared with the overall arrangement, the arrangement of the present application can reduce weight and facilitate the operator to install the wear-resistant liner inside the discharge hopper body 1.

[0029] In some embodiments, as Figures 1 to 5 As shown, the fixed structure includes a wedge-shaped slide rail 3 arranged on the inner wall of the discharge hopper body 1, and a wedge-shaped groove 21 is provided on the strip wear-resistant liner 2, which is slidably matched with the wedge-shaped slide rail 3; wherein, the wedge-shaped groove 21 has a cross piece 22 near the top of the strip wear-resistant liner 2, and the cross piece 22 is used to abut against the top of the wedge-shaped slide rail 3.

[0030] It should be noted that the strip wear-resistant lining 2 is slidably fitted with the wedge-shaped groove 21 and the wedge-shaped slide rail 3. On the one hand, it can enable the strip wear-resistant lining 2 to slide into place, and on the other hand, it can play a role in lateral limitation of the strip wear-resistant lining 2 to avoid the strip wear-resistant lining 2 from separating from the inner wall of the discharge hopper.

[0031] By providing a cross piece 22 at the top position of the wedge-shaped groove 21, the sliding position of the strip wear-resistant lining plate can be limited, thereby reducing the occurrence of the strip wear-resistant lining plate 2 falling downward.

[0032] In some embodiments, as Figures 1 to 5 As shown, the fixed structure includes a T-shaped slide rail 4 arranged on the inner side wall of the discharge hopper body 1, and the strip wear-resistant lining 2 has a T-shaped groove 23 that slides with the T-shaped slide rail 4; wherein, the T-shaped groove 23 has a cross bar 22 near the top of the strip wear-resistant lining 2, and the cross bar 22 is used to abut against the top of the T-shaped slide rail 4.

[0033] It should be noted that by providing the T-shaped slide rail 4, the T-shaped slot 23 on the wear-resistant strip liner 2 can slide with the T-shaped slide rail 4, thereby acting as a lateral limit for the wear-resistant strip liner 2. Lateral limit here refers to a direction perpendicular to the corresponding inner sidewall of the discharge hopper. After the wear-resistant strip liner 2 slides into place, the crosspiece 22 contacts the top of the T-shaped slide rail 4, limiting further sliding of the wear-resistant strip liner 2.

[0034] In some embodiments, as Figures 1 to 5As shown, the sliding directions of the several strip-shaped wear-resistant liners 2 on each inner side wall of the discharge hopper body 1 are the same, and the top of the discharge hopper body 1 has a connecting component 5 for connecting the several strip-shaped wear-resistant liners 2 on the same side; the top of the connecting component 5 has a threaded hole, and the threaded hole on the connecting component 5 can cooperate with the lifting ring thread.

[0035] It should be noted that when the hopper body 1 is mounted on the concrete mixing station's mounting bracket, the lifting ring on the connecting component 5 needs to be removed. To remove the wear-resistant strip liner 2, the hopper body 1 is removed from the mounting bracket, and the lifting ring is then installed on the connecting component 5. This allows all the wear-resistant strip liners 2 on the same side of the hopper body 1 to be pulled out at once, improving removal efficiency. The lifting ring is prior art and will not be described in detail here.

[0036] In some embodiments, as Figures 1 to 5 As shown, a receiving box is fixedly provided on the outer peripheral wall of the discharge hopper body 1, and the top of the receiving box has an opening, and the receiving box can accommodate a lifting ring; wherein, the lifting ring has a screw segment, and the lifting ring is threadedly engaged with the connecting component 5 through the screw segment.

[0037] It should be noted that, by providing a receiving box on the outer peripheral wall of the discharge hopper body 1, the lifting ring can be stored, thereby reducing the possibility of the lifting ring being lost.

[0038] In some embodiments, as Figures 1 to 5 As shown, the connecting component 5 includes a connecting plate 51, which has a bent rod 52 corresponding to each strip-shaped wear-resistant lining plate 2; each strip-shaped wear-resistant lining plate 2 has a socket 24 that is plugged into the corresponding bent rod 52; an elastic layer is provided at the position where the connecting plate 51 contacts the discharge hopper body 1 to reduce scratches between the connecting plate 51 and the inner wall of the discharge hopper body 1.

[0039] It should be noted that after the strip wear-resistant plate is installed in the discharge hopper body 1, the connecting plate 51 is installed on the top of the strip wear-resistant lining plate 2, and the bent rod 52 is plugged into the socket 24 on the strip wear-resistant lining plate 2; through the above arrangement, the connecting plate 51 can be connected to all the strip wear-resistant lining plates 2 on the same side, and when disassembly is required, all the strip wear-resistant lining plates 2 on the same side can be removed at one time.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
