AI Technical Summary
When the existing crusher puts the material into the interior, the material tends to fall into the sides of the two rollers, resulting in that part of the material cannot be squeezed and crushed, and needs to be taken out and put again later, which is inconvenient to operate.
A rotating plate and a supporting plate are set inside the feeding port of the crusher body. The rotating plate and the supporting plate are separated or engaged by a moving mechanism to form a V-shaped feeding hopper. The rotating plate contacts the crushing roller to prevent the material from falling into the side. The pressure sensor is used to detect the load and the gear is driven by the motor to drive the tooth plate to move the supporting plate to achieve automatic adjustment.
It effectively prevents materials from falling into the sides of the crushing rollers, ensuring that the materials are squeezed and crushed between the two sets of crushing rollers, simplifying the feeding process and improving the crushing efficiency.

[0002] Crusher equipment is widely used in many sectors, including mining, smelting, building materials, highways, railways, water conservancy, and the chemical industry. Among them, the double-roll crusher is a common crushing device. The double-roll crusher utilizes a pair of counter-rotating rollers to crush the material passing between them. However, when feeding material into the crusher, existing crushers tend to cause it to fall between the rollers, preventing it from being crushed and requiring subsequent removal and re-feeding, which is inconvenient. Therefore, a crusher with easier feeding is proposed. Utility Model Content
[0003] In order to solve the problem that when materials are fed into the existing crusher, the materials easily fall into the sides of the two rollers, and this part of the materials cannot be squeezed and crushed, and needs to be taken out and fed again later, which is inconvenient, the present application provides a crusher that is easy to feed.

The rotating plates can rotate based on the side walls of the feeding port of the crusher body. The contact surfaces of the two groups of rotating plates are located between the two groups of crushing rollers. When the rotating plates are arranged horizontally, the distance between the rotating plates and their rotating ends is greater than the distance between the rotating plates and the crushing rollers. Support plates are provided at the bottom of the rotating plates, and grooves adapted to the support plates are opened on the surface of the crusher body. The support plates move inside the grooves through a moving mechanism, and the support plates can support the rotating plates or be separated from them.
[0006] Preferably, connecting plates are fixedly connected to both sides of the inner wall of the feed port of the crusher body, and the connecting plates are rotatably connected to the rotating plate through a rotating shaft, and the upper surface of the connecting plate is inclined toward the rotating plate.

[0017] The following is combined with Figure 1-4 This application is described in further detail.
[0018] An embodiment of the present application discloses a crusher that is easy to feed, including a crusher body 1. Rotating plates 2 are provided on both sides of the inner side of the feeding port of the crusher body 1. The rotating plates 2 can rotate based on the side walls of the feeding port of the crusher body 1. The contact surfaces of the two groups of rotating plates 2 are located between the two groups of crushing rollers. When the rotating plates 2 are arranged horizontally, the distance between the rotating plates 2 and their rotating ends is greater than the distance between the rotating plates 2 and the crushing rollers. Support plates 5 are provided at the bottom of the rotating plates 2. Notches that are adapted to the support plates 5 are opened on the surface of the crusher body 1. The support plates 5 move inside the notches through a moving mechanism. The support plates 5 can support the rotating plates 2 or be separated from them.
[0019] In this embodiment, two sets of rotating plates 2 are provided, and the contact surfaces of the two sets of rotating plates 2 are located between the two sets of crushing rollers. When materials are fed into the feeding port of the crusher body 1, the moving mechanism can be used to drive the support plate 5 to separate from the rotating plate 2, so that the rotating plate 2 rotates downward until it contacts the crushing roller. The two sets of rotating plates 2 form a V-shaped feeding hopper, and the rotating plates 2 separate the sides of the crushing roller to prevent the materials from moving to the sides of the crushing roller, thereby ensuring that the fed materials are located between the two sets of crushing rollers and can be squeezed and crushed.
[0020] Furthermore, connecting plates 3 are fixedly connected on both sides of the inner wall of the feeding port of the crusher body 1. The connecting plates 3 are rotatably connected to the rotating plate 2 through the rotating shaft 4. The upper surface of the connecting plate 3 is inclined toward the rotating plate 2. By setting the connecting plate 3 and the rotating shaft 4, the rotating plate 2 can be rotatably installed inside the crusher body 1, and by setting the upper surface of the connecting plate 3 as an inclined surface, it is ensured that the material can fall onto the rotating plate 2 along the inclined surface, preventing the material from being trapped on the connecting plate 3.
[0021] Furthermore, a pressure sensor 7 is provided on the upper surface of each support plate 5 , and the pressure sensor 7 is used to detect the load of the rotating plate 2 .
[0022] Furthermore, several groups of support plates 5 are provided, and the support plates 5 are all arranged perpendicular to the central axis of the rotating shaft 4. One end of the support plates 5 located on the same side is fixedly connected to a movable plate 6, and the movable plate 6 is located outside the feeding port of the crusher body 1.
[0023] Specifically, pressure sensor 7 typically consists of a pressure-sensitive element and a signal processing unit. Depending on the type of test pressure, pressure sensor 7 can be classified as a gauge pressure sensor, a differential pressure sensor, or an absolute pressure sensor. In this embodiment, pressure sensor 7 can be any existing type that can monitor the load of rotating plate 2. In practical applications, weighing the crushed material is often necessary. By providing pressure sensor 7, automatic measurement of the crushed material's weight can be achieved.
[0024] Furthermore, one end of the movable plate 6 is fixedly connected to a tooth plate 9, and the two groups of tooth plates 9 are centrally symmetrical based on the middle of one side of the feeding port of the crusher body 1. The surface of the crusher body 1 is rotatably connected to a gear 10, and the gear 10 is located between the two groups of tooth plates 9 and meshes with them. The surface of the crusher body 1 is fixedly connected to a frame 11, and the surface of the frame 11 is fixedly connected to a motor 8, and the output shaft of the motor 8 is fixedly connected to the gear 10.
[0025] In this embodiment, by driving the motor 8 to rotate forward and reverse, the gear 10 can be driven to rotate forward and reverse, thereby driving the two sets of tooth plates 9 to move closer to or away from each other, thereby driving the movable plate 6 and the support plate 5 to move, so that the support plate 5 moves to the bottom of the rotating plate 2 or moves away from the bottom of the rotating plate 2.
[0026] It should be noted that the switch interface of the motor 8 is connected to the external power supply via a wire, and the circuits and related drivers involved are all conventional technologies and will not be described in detail here.
[0027] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships.
