Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Example 1:

[0035] Figures 1 to 4 An embodiment of the chute of this utility model is shown. The chute of this embodiment includes a chute body 1 and a material channel 2 formed on the chute body 1. The two sides of the material channel 2 are arranged in a V-shape. Multiple bottom plates 3 are detachably provided on the bottom wall of the material channel 2. Each bottom plate 3 is connected sequentially along the extension direction of the material channel 2. At least one horizontal row of crushing blocks 4 is provided on each bottom plate 3. The crushing blocks 4 in adjacent rows are arranged alternately.

[0036] The material channel 2 is arranged in a V-shape on both sides, making the inlet (wide opening) wider and the outlet (narrow opening) narrower. In use, the chute body 1 is tilted, with the wide opening facing upwards and the narrow opening downwards. Material (such as stone powder blocks dewatered by a high-frequency screen) is fed into the material channel 2 and, under gravity, passes through the crushing blocks 4, where it is cut and crushed into small particles before falling out through the narrow opening of the chute body 1. The chute contains crushing blocks 4, which effectively crush the materials passing through. Furthermore, the bottom plate 3 is detachably mounted on the bottom wall of the material channel 2, facilitating disassembly and replacement to change the number of rows of crushing blocks 4, meeting different crushing requirements and demonstrating strong adaptability.

[0037] Furthermore, such as Figures 2 to 4 As shown, in this embodiment, slots 5 are provided on both sides of the material channel 2, and the bottom plate 3 is respectively secured in the slots 5 on both sides of the material channel 2. The bottom plate 3 enters from the wide opening of the material channel 2 for easy insertion into the slots 5. Furthermore, since the two sides of the material channel 2 are arranged in a V-shape, the slots 5 on both sides of the material channel 2 are also arranged in a V-shape, thereby restricting the position of each bottom plate 3 and ensuring that the bottom plate 3 can only be inserted and removed from the wide opening of the material channel 2, and will not fall out from the narrow opening. The lengths of each bottom plate 3 are different to meet different positional requirements.

[0038] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the upper surface of the base plate 3 facing the wide opening of the material channel 2 is provided with an upper chamfered surface 31, and the lower surface of the other side is provided with a lower chamfered surface 32. The joint of adjacent base plates 3 is connected by the upper chamfered surface 31 and the lower chamfered surface 32. On the one hand, in the adjacent base plates 3, the lower chamfered surface 32 of the upper base plate 3 overlaps with the upper chamfered surface 31 of the lower base plate 3, which helps to prevent materials from getting stuck between adjacent base plates 3; on the other hand, the upper chamfered surface 31 of the uppermost base plate 3 facilitates the sequential entry of materials into the material channel 2.

[0039] Furthermore, in this embodiment, the chute body 1 is provided with an upper cover 11 above the narrow opening of the material channel 2. This prevents material from flying out from above the narrow opening of the material channel 2, allowing the material to smoothly enter the conveying device 8 below. Preferably, the upper side of the material channel 2 is open to facilitate the disassembly and assembly of the bottom plate 3. Of course, in other embodiments, a cover can also be provided on the upper side of the material channel 2 to prevent material splashing.

[0040] Furthermore, in this embodiment, the upper cover 11 is tilted outwards on the side facing the entrance of the material channel 2, which facilitates material reception and allows the material to smoothly enter the conveying device 8 below.

[0041] Furthermore, the crushing block 4 is a steel block. The crushing block 4 is perpendicular to the base plate 3. A horizontal row is a row arranged along the material channel 2. A horizontal row of crushing blocks 4 includes multiple crushing blocks 4 arranged at intervals along the material channel 2.

[0042] Example 2:

[0043] Figure 5 and Figure 6 An embodiment of the sand and gravel processing system of this utility model is shown. The sand and gravel processing system of this embodiment includes a wastewater treatment device 6, a hydrocyclone 7, a conveying device 8, and a chute in the first embodiment. The inlet of the hydrocyclone 7 is connected to the outlet of the wastewater treatment device 6. The wide opening of the chute body 1 faces upward and is connected to the outlet of the hydrocyclone 7. The narrow opening of the chute body 1 faces downward and is located above the conveying device 8.

[0044] Material from the hydrocyclone 7 outlet (such as stone powder blocks dewatered by a high-frequency screen) is fed into material channel 2. Under gravity, it passes through crushing blocks 4, where it is cut and crushed into small particles. These particles then fall through the narrow opening of the chute body 1 onto the conveying device 8 below. The stone powder on the conveying device 8 (such as a belt conveyor) is evenly mixed with the sand produced in the rod mill and three-screen workshops before entering the finished product silo. This ensures uniform addition of stone powder and guarantees a stable and qualified content of the finished sand and gravel. This sand and gravel processing system possesses all the advantages of a chute, effectively crushing the materials passing through it. Furthermore, it is easy to disassemble and reassemble to change the number of rows of crushing blocks 4, meeting different crushing requirements and exhibiting strong adaptability.

[0045] Furthermore, in this embodiment, the upper part of the chute body 1 is hinged to the hydrocyclone 7, and the lower part of the chute body 1 is obliquely supported on the hydrocyclone 7.

[0046] Furthermore, in this embodiment, the hydrocyclone 7 is provided with an elastic component 9, and the lower part of the chute body 1 is inclinedly supported on the elastic component 9. In this way, the chute body 1 can have a certain vibration capability when the material passes through, which is conducive to the material sliding down.

[0047] Furthermore, in this embodiment, the elastic component 9 includes a pad 91 and a plurality of springs 92. The pad 91 is fixed to the hydrocyclone 7 by the plurality of springs 92, and the chute body 1 is obliquely supported on the pad 91.

[0048] Furthermore, in this embodiment, a support rod 12 is provided at the lower part of the chute body 1, and a support wheel 121 is provided on the support rod 12. An arc-shaped guide groove 71 is provided on the hydrocyclone 7. The arc-shaped guide groove 71 is located below the rotation center of the chute body 1, and the center of the arc of the arc-shaped guide groove 71 coincides with the rotation center of the chute body 1. The support wheel 121 slides within the arc-shaped guide groove 71. The arc-shaped guide groove 71 provides upward support to the support wheel 121, reducing the stress at the hinge of the chute body 1 and improving its service life. Preferably, the rotation center (hinge center) of the chute body 1 is located directly above the arc-shaped guide groove 71, ensuring that the arc-shaped guide groove 71 provides upward support to the support wheel 121.

[0049] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
