[0033] Figure 1 is a structural schematic diagram of a chute according to an embodiment of the present application. As shown in Figure 1 , and referring to Figure 2 , the present embodiment provides a chute 10, which comprises a discharge port 102, and the discharge port 102 faces downward. Along the material conveying direction, the rear edge 103 of the discharge port 102 is below the front edge 104 of the discharge port.

[0034] In the embodiment of the utility model, the setting that the rear edge 103 of the discharge port 102 is below the front edge 104 of the outlet of the discharge pipe makes the discharge port 102 adapt to the gradually rising conveying surface of the belt conveyor 70 from back to front, compared with the horizontal discharge port 102, the discharge port 102 of the chute 10 in the embodiment of the utility model can reduce the height difference between the discharge port 102 and the conveying surface of the belt conveyor 70 as much as possible without blocking the conveying of the broken material on the belt conveyor 70, reduces the impact of the material on the belt conveyor 70, avoids the impact of the broken material on the belt conveyor 70 when the broken material falls on the conveying surface of the belt conveyor 70 from the relatively high place at a large speed, and avoids the damage of the belt conveyor 70 to affect the service life of the belt conveyor 70. Especially for some heavy jaw crushers, the heavy jaw crusher has large capacity, the material size is large, so the gravitational potential energy of the material is large, and the impact on the chute 10 and the belt conveyor 70 is large, and the protection effect of the setting on the belt conveyor 70 is more obvious.

[0035] In some embodiments of the utility model, as shown in Figure 1 The outlet of the discharge pipe is the discharge port 102. The rear wall of the discharge pipe includes a stepped structure 105 to form a material retention area on the rear wall of the discharge pipe. The lower edge of the rear wall of the discharge pipe is the rear edge 103 of the discharge port 102.

[0036] The broken material 60 will be temporarily retained in the corner of the stepped structure 105 during rolling along the discharge pipe, especially the relatively small material 60 is more likely to be retained in the corner of the stepped structure 105, forming a material retention area, and the material 60 accumulated in the material retention area can form a slope material lining, which uses the material lining to reduce the gravitational potential energy of the rolling material 60, reduces the noise generated by the collision of the material 60, and facilitates the slow rolling of the material to the belt conveyor 70. The chute 10 of the conventional jaw crusher needs to withstand the impact and friction of the material, so a steel plate with sufficient thickness is needed to prevent the material from being punched or ground through, which results in the self-weight of the box body 101 being relatively heavy, and the direct impact of the material on the steel plate generates a lot of noise, which can harm workers. The setting of the embodiment can reduce the wall thickness of the chute 10 and reduce the noise, and also can protect the chute 10 to a certain extent.

[0037] In some other embodiments of this utility model, the rear wall of the discharge pipe includes a corrugated structure, which gradually slopes downward from back to front along the material conveying direction. During the rolling process along the discharge pipe, a portion of the crushed material 60 will temporarily remain within the corrugations of the corrugated structure, especially smaller pieces of material 60, forming a material retention area. The accumulation of material 60 in this retention area forms a sloping lining, which reduces the gravitational potential energy of the rolling material, decreases the noise generated by material collisions, and facilitates the slow rolling of material onto the conveyor belt 70. Simultaneously, this design also provides some protection for the chute 10.

[0038] In some embodiments of this utility model, such as Figure 2 As shown, when the discharge pipe is small, the outlet of the discharge pipe can extend into the guide chute of the belt conveyor 70, which can also reduce the height difference between the discharge port 102 and the conveying surface of the belt conveyor 70, further reducing the impact of the material on the belt conveyor 70, and preventing the belt conveyor 70 from being easily damaged when broken material falls from a relatively high place onto the conveying surface of the belt conveyor 70 at a certain speed, thus affecting the working life of the belt conveyor 70.

[0039] In some embodiments of this utility model, such as Figure 1 As shown, the rear wall of the discharge pipe also includes a discharge section 108, the upper edge of which is connected to the lower edge of the stepped structure 105 or the corrugated structure. Along the material conveying direction, the lower edge of the discharge section 108 is in front of the upper edge. The lower edge of the discharge section 108 is the rear edge 103 of the discharge port 102. In other words, along the material conveying direction, the discharge section 108 slopes downwards and forwards, forming a forward ramp. This arrangement further reduces the gravitational potential energy of the material 60, reduces the speed at which the material 60 rolls onto the conveyor surface of the belt conveyor 70, and also gives the material 60 a velocity component in the same direction as the conveyor surface of the belt conveyor 70. This also reduces the impact of the material on the conveyor surface of the belt conveyor 70 and facilitates material transport.

[0040] In some embodiments of this utility model, such as Figure 1 As shown, the front wall of the discharge pipe is rotatably configured, and the lower edge of the front wall of the discharge pipe is the front edge 104 of the discharge port 102.

[0041] The rotatable front wall of the discharge pipe prevents some broken material 60 from getting stuck at the front wall of the discharge pipe due to its size exceeding the height difference between the discharge port 102 and the conveyor surface of the belt conveyor 70, thus preventing it from exiting the discharge port 102. When large broken material exits from the discharge port 102 and moves with the conveyor surface of the belt conveyor 70, the front wall of the discharge pipe rotates outward, allowing the large broken material 60 to pass smoothly. This design is beneficial for both material transportation and the protection of the discharge pipe and the belt conveyor 70.

[0042] Further, in some embodiments of the present application, as shown in Figure 1 The front wall of the discharge pipe is made of rubber material. Compared with the front wall of the discharge pipe made of rigid material, the rubber material is soft. When the material falling at a certain position is relatively large, the rubber material at the corresponding position is in contact with the material, and only the rubber at the position is turned over, so that the whole front wall 106 of the discharge pipe is not turned over to cause the leakage of bulk material and dust. Of course, the front wall of the discharge pipe made of rubber material can also be turned over as a whole.

[0043] In some other embodiments of the present application, the front wall of the discharge pipe can also be made of rigid material, for example, the front wall of the discharge pipe is made of steel plate.

[0044] In some embodiments of the present application, the discharge pipe can be a circular pipe. When the front wall 106 of the discharge pipe is not turned over, the front wall of the discharge pipe is in contact with the rear wall of the discharge pipe to form the discharge pipe. The front wall of the discharge pipe and the rear wall of the discharge pipe define the outlet of the discharge pipe and the inlet of the discharge pipe. Of course, in some other embodiments of the present application, as shown in Figure 1 The cross section of the discharge pipe is quadrangular, and the discharge pipe further comprises two side walls. Each side wall is connected with the corresponding side edge of the rear wall of the discharge pipe, that is, the two side walls are connected with the rear wall of the discharge pipe, respectively. When the front wall 106 of the discharge pipe is not turned over, the front wall of the discharge pipe is in contact with the two side walls of the discharge pipe to form the discharge pipe. The front wall of the discharge pipe, the rear wall of the discharge pipe and the two side walls define the outlet of the discharge pipe and the inlet of the discharge pipe. Of course, in some other embodiments of the present application, the cross section of the discharge pipe can also be other shapes.

[0045] In some embodiments of the present application, as shown in Figure 2 The chute 10 further comprises a box body 101. The box body 101 comprises an opening and an outlet. The opening is a feeding port, and the outlet is arranged on the bottom wall of the box body 101. The inlet of the discharge pipe is connected with the outlet.

[0046] The crushed material enters the opening of the box body 101, flows out from the outlet into the discharge pipe, and finally falls on the conveying surface of the belt conveyor 70 from the outlet of the discharge pipe. After the crushed material enters the box body 101, a part of the material will be temporarily stored in the bottom corner of the box body 101, especially the smaller material is more likely to be retained in the bottom corner of the box body 101, forming a material retention area. The material accumulated in the material retention area of the box body 101 can form an inclined material lining. The material lining is used to reduce the gravitational potential energy of the falling material, and reduce the noise generated by the collision between the material and the box body 101.

[0047] In some embodiments of the present application, as shown in Figure 1As shown, the chute 10 further comprises a pressing plate 107. The pressing plate 107 is configured to fix the upper edge of the front wall of the discharge pipe on the box 101.

[0048] In some embodiments of the present application, the upper edge of the front wall of the discharge pipe is hinged to the box 101. When the front wall of the discharge pipe is made of rigid material, the front wall of the discharge pipe is hinged to the box 101, and the front wall of the discharge pipe can be flipped over.

[0049] Further, in some embodiments of the present application, the front wall of the discharge pipe is hinged to the box 101 through a hinge or a hinge.

[0050] The present application also provides a jaw crusher, as shown in the accompanying drawings. Figure 2 As shown, the jaw crusher comprises a moving jaw 30, a stationary jaw 20, and a chute 10, the moving jaw 30 and the stationary jaw 20 define a downwardly directed crushed material outlet, and the feed inlet of the chute 10 is below the crushed material outlet, and the chute 10 is the chute 10 of any of the above embodiments. The feed inlet of the chute 10 is below the crushed material outlet.

[0051] In some embodiments of the present application, the width of the feed inlet is greater than the width of the moving jaw 30 and the stationary jaw 20. This arrangement ensures that all the side material of the moving jaw 30 enters the box 101, so as to prevent the side material of the moving jaw 30 from leaking out, causing dust to float in the plant or the plant to be dirty and messy, causing harm to the human body, and affecting the maintenance of the equipment.

[0052] At this point, those skilled in the art should realize that, although the present application has been shown and described in detail in the above embodiments, many other variants or modifications can be determined or deduced directly according to the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
