All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0022] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-3As shown, a chute for a crusher includes an upper chute 1, a middle chute 2, and a lower chute 3. A funnel 4 is provided at the upper end of the upper chute 1. The lower end of the upper chute 1 is connected to the middle of the middle chute 2, and the lower end of the middle chute 2 is connected to the upper end of the lower chute 3. The upper chute 1, the middle chute 2, and the lower chute 3 are all inclined, with the inclination angles of the upper chute 1 and the lower chute 3 being greater than the inclination angle of the middle chute 2. An inspection port 5 is provided at the upper end of the middle chute 2, and vibrators 6 are provided on both sides of the middle chute 2. This invention divides the chute into upper chute 1, middle chute 2, and lower chute 3, and provides an inspection port 5 on the middle chute 2 for quick unblocking when clogged. Furthermore, the addition of vibrators 6 reduces the likelihood of material blockage.
[0026] In this embodiment, a dust suction pipe 7 is provided at the upper end of the middle chute 2, and a vacuum cleaner is connected to the outside of the dust suction pipe 7. This utility model can use the vacuum cleaner and the dust suction pipe 7 to suck away the flying dust generated inside the chute, thereby reducing the environmental dust during material feeding.
[0027] In this embodiment, the upper chute 1 is inclined at an angle of 70-80 degrees, the middle chute 2 is inclined at an angle of 20-30 degrees, and the lower chute 3 is inclined at an angle of 60-70 degrees. The length of the upper chute 1 is more than 2m, the length of the middle chute 2 is 0.5-1m, and the length of the lower chute 3 is 0.2-0.5m. The middle chute 2 of this invention can absorb the potential energy generated by gravity when the material falls, preventing damage to the crusher from vertical material discharge.
[0028] In this embodiment, the inner walls of the upper chute 1, the middle chute 2, and the lower chute 3 are all provided with wear-resistant layers. The thickness of the wear-resistant layer is 1-2 cm. The wear-resistant layer of this utility model can be used to increase the wear resistance of the inner walls of the upper chute 1, the middle chute 2, and the lower chute 3, and extend the service life of this utility model.
[0029] In this embodiment, in order to improve the stability of the connection between the upper chute 1 and the middle chute 2, and in order to improve the stability of the connection between the middle chute 2 and the lower chute 3, fixing members are provided between the upper chute 1 and the middle chute 2, and between the middle chute 2 and the lower chute 3. The fixing members are connected by hooks.
[0030] In this embodiment, the upper chute 1 and the middle chute 2 are both multi-segmented. By using a multi-segmented design, when a local section is damaged, the corresponding chute segment is directly replaced.
[0031] In this embodiment, to further extend the service life of the present invention, the upper chute 1, the middle chute 2, and the lower chute 3 are all made of metal.
[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
