[0031] First Embodiment

[0032] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the cone crusher feed plate protection device provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the protective shield. Figure 3 for Figure 1 The diagram shows a front sectional view of the structure. The cone crusher distribution plate protection device includes: a distribution plate 1, and a protective component 2 is provided at the bottom of the distribution plate 1. The protective component 2 includes a protective cover 21 and a threaded sleeve 22.

[0033] The first buffer assembly 3 is disposed inside the protective cover 21. The first buffer assembly 3 includes a connecting sleeve 31, which is fixedly connected to the bottom of the protective cover 21. A buffer spring 32 is movably installed inside the connecting sleeve 31. A first sliding block 33 is fixedly connected to the top of the buffer spring 32. A rotating ball 34 is movably embedded inside the top of the first sliding block 33. The rotating ball 34 is fixedly connected to the bottom of the material distribution plate 1.

[0034] The second buffer assembly 4 is disposed on the surface of the connecting sleeve 31, and the second buffer assembly 4 includes a connecting block 41, a spring slide rod 42, and a second sliding block 43.

[0035] The transmission assembly 5 is disposed inside the protective cover 21, and the transmission assembly 5 includes a rotating block 51 and a transmission rod 52.

[0036] The material distribution plate 1 is frustum-shaped with a certain slope and flow guiding structure at the top. When the material falls onto the material distribution plate, it will be evenly dispersed in all directions along the slope and flow guiding direction of the surface under the action of the material distribution plate, so that the material can enter the crushing chamber more evenly. The function of the protective component 2 is to connect and protect. The function of the first buffer component 3 is to reduce shock. The connecting sleeve 31 is cylindrical and is fixedly connected to the surface of the top of the bottom connecting plate of the protective cover 21. The bottom of the first sliding block 33 is slidably embedded in the inside of the connecting sleeve 31 and fixedly connected to the top of the buffer spring 32. A ball groove is opened at the top. The rotating ball 34 is rotatably embedded in the groove, so as to drive the material distribution plate 1 to rotate in all directions. The function of the second buffer component 4 is to connect and reduce shock. The function of the transmission component 5 is to indirectly transmit.

[0037] The protective cover 21 is fixedly connected to the bottom of the material distribution plate 1, and the threaded sleeve 22 is fixedly connected to the bottom of the protective cover 21.

[0038] The protective cover 21 is made of highly resilient rubber. A connecting ring is fixedly connected to the top and a connecting plate is fixedly connected to the bottom. When the material distribution plate 1 is impacted, the material distribution plate 1 will squeeze the protective cover 21 to expand and contract, which can protect the internal components. The threaded sleeve 22 has a threaded groove inside for threaded connection with the top of the crushing wall.

[0039] The connecting block 41 is fixedly connected to the outer surface of the connecting sleeve 31, the spring slide rod 42 is fixedly connected to the inside of the connecting block 41, and the second sliding block 43 is movably connected to the surface of the spring slide rod 42.

[0040] The second buffer assembly 4 consists of four components. The four connecting blocks 41 are fixedly connected to the outer surface of the connecting sleeve 31 in a circumferential array, and each has a groove inside. The spring slide rod 42 is composed of a spring movably sleeved on the outer surface of a rod. The upper and lower ends of the four connecting rods are fixedly connected to the inner surfaces of the grooves at the upper and lower ends of the four connecting blocks 41. The four second sliding blocks 43 are slidably sleeved on the outer surfaces of the four connecting rods and fixedly connected to the top of the four springs.

[0041] The rotating block 51 is movably connected to the inner surface of the top of the protective cover 21 and the surface of the second sliding block 43, and the two ends of the transmission rod 52 are movably connected to the surface of the rotating block 51.

[0042] There are four transmission components 5. Each pair of rotating blocks 51 forms a group. In each group, each pair of rotating blocks 51 is rotatably connected to the surface of each second sliding block 43 and the inner surface of the connecting ring at the top of the protective cover 21. The two ends of each transmission rod 52 are rotatably connected to the surfaces of the two rotating blocks 51 in each group. When the side of the material distribution plate 1 is impacted, the side of the material distribution plate 1 rotates, and the transmission rod 52 in the tilt direction is subjected to pressure. The angle of the transmission rod 52 under pressure changes, and one end pushes the second sliding block 43 to slide downward and squeeze the spring. Under the action of the spring force, the material distribution plate 1 is reset, thereby reducing the vibration of the side of the material distribution plate 1.

[0043] The working principle of the cone crusher feed plate protection device provided by this utility model is as follows:

[0044] When the material distribution plate 1 is impacted from above, the first sliding block 33 presses down to compress the buffer spring 32. Due to the elastic force of the buffer spring 32, the material distribution plate 1 is driven to return to its original position, reducing the amplitude of the vertical vibration of the material distribution plate 1. When the side of the material distribution plate 1 is impacted, the rotating ball 34 rotates, and the angle of the transmission rod 52 changes. One end drives the second sliding block 43 to move up and down while pulling the rotating block 51 to rotate. Due to the elastic force of the spring slide rod 42, the amplitude of the vertical vibration of the spring slide rod 42 is reduced, thereby achieving shock absorption on the side of the material distribution plate 1.

[0045] Compared with related technologies, the cone crusher feed plate protection device provided by this utility model has the following beneficial effects:

[0046] This utility model provides a protective device for the distribution plate of a cone crusher. By setting a first buffer component 3 inside the protective cover 21, the distribution plate 1 can be damped. At the same time, a second buffer component 4 is set on the outer surface of the connecting sleeve 31 and connected to the bottom of the distribution plate 1 through the transmission component 5, thereby buffering and damping the side of the distribution plate 1. This increases the buffering and damping effect of the distribution plate 1 and prevents the distribution plate 1 from being overloaded.

It can be threaded inside the threaded sleeve 22 and fitted onto the surface of the insert block 61. The groove inside the threaded block 72 has two holes. When the threaded block 72 is fully threaded into the threaded sleeve 22, the fixing block 63 can be embedded in the two holes under the elastic force of the fixing spring 62, thereby fixing the threaded block 72 and preventing it from loosening.

[0053] The threaded sleeve 22 is provided with an extrusion assembly 8. The extrusion assembly 8 includes a connecting rod 81. One end of the connecting rod 81 is fixedly connected to the top of the fixing block 63, and the other end of the connecting rod 81 is fixedly connected to an extrusion plate 82.

[0054] There are two extrusion components 8. The two connecting rods 81 are L-shaped, with one end fixedly connected to the top of the two fixing blocks 63 respectively. The two extrusion plates 82 are fixedly connected to the bottom of the other end of the two connecting rods 81 respectively.

[0055] The working principle of the cone crusher feed plate protection device provided by this utility model is as follows:
