[0002] Impact crusher, also known as impact crusher, is mainly used for material processing in metallurgy, chemical industry, mineral mining, etc., which often need to be moved. It is especially used for operations of mobile stone such as highways, railways, hydropower projects, etc. It can be configured in a variety of forms according to the type, scale and requirements of finished materials. At present, mobile crushing stations in my country are mostly used for ore processing, crushing larger ores into standard crushed materials to meet subsequent production needs. Most of the existing crushers are fixed, so it is necessary to transport the mineral raw materials. Due to the large size and heavy weight of the mineral raw materials, it is difficult to transport the mineral raw materials and the efficiency is low. If rollers are directly set at the bottom of the crusher, the stability during operation cannot be guaranteed. Utility Model Content

[0023] Example:

[0024] See also Figure 1-Figure 5 As shown, a highly stable mobile crusher comprises a bottom plate 2, a body 1 is fixed on the upper surface of the bottom plate 2, a traction part 4 is arranged on the front side of the upper surface of the body 1 to facilitate traction of the equipment, lower extension plates 3 are symmetrically arranged on both side surfaces of the bottom plate 2, a rotating shaft 5 is installed on the outer surface of the lower extension plate 3 through a bearing, a roller 6 is arranged on the outer side of the rotating shaft 5, and the device is driven to move as a whole through the rollers 6 at the four corners, a fastening ring 7 is arranged on the inner side of the lower extension plate 3, and the roller 6 passes through the fastening ring 7. When not subjected to force, the fastening ring 7 is in a relaxed state and will not squeeze the rotating shaft 5. On the contrary, when the fastening ring 7 is tightened, the fixing of the rotating shaft 5 can be ensured, a notch is provided above the fastening ring 7, and extrusion plates 8 are symmetrically arranged at both ends of the notch of the fastening ring 7, and the two extrusion plates 8 are arranged in parallel, and the extrusion plates 8 are squeezed to make the two pressure plates approach, and then the tightening of the fastening ring 7 is controlled, and the bottom plate 2 Lower protrusions 9 are evenly arranged below the surfaces of both sides, and sliding rods 10 are symmetrically and slidably installed between the multiple lower protrusions 9 so that the sliding rods 10 can only slide horizontally. The two sliding rods 10 are symmetrically arranged, and the ends of the sliding rods 10 are placed on the inner sides of the lower extension plates 3. The ends of the sliding rods 10 are in contact with one of the extrusion plates 8. When the two sliding rods 10 move away from each other, the extrusion plate 8 can be squeezed to tighten the fastening ring 7. An extrusion head 11 is arranged at the end of the sliding rod 10 away from the lower extension plate 3, and the end of the extrusion head 11 is hemispherical. An edge plate is arranged at the center of both sides of the bottom plate 2, and a control shaft 13 is vertically penetrated by the bearing on the surface of the edge plate. An elliptical extrusion disk 14 is arranged at the bottom of the control shaft 13, and the elliptical extrusion disk 14 is placed between the two sliding rods 10. The two extrusion heads 11 are respectively in contact with the surfaces of the elliptical extrusion disk 14, and the elliptical extrusion disk 14 can be rotated to push the extrusion head 11 to achieve fixation of the equipment.

[0025] Please refer to Figure 5 As shown, a spring A12 is sleeved on the surface of the slide rod 10, and the spring A12 is placed between the extrusion head 11 and one of the lower protrusions 9. The elastic force of the spring A12 is used to make the two slide rods 10 approach each other when no force is applied, the fastening ring 7 is in a relaxed state, and the vertical drop of the extrusion head 11 is greater than that of the slide rod 10, so as to provide a force point for the spring A12.

[0026] Please refer to Figure 2 and Figure 5 As shown, a knob 15 is provided on the top of the control shaft 13 to facilitate external control of the elliptical extrusion disk 14.

[0027] Please refer to Figure 4 As shown, a ratchet disk 16 is provided on the surface of the control shaft 13, and the ratchet disk 16 is placed on the inner side of the plate body, and a storage hole 17 is opened on the inner side of the plate. A wedge block 18 is slidably installed inside the storage hole 17, and the wedge block 18 is meshed with the ratchet disk 16. A pull-twist 19 is provided on the end of the wedge block 18 away from the ratchet disk 16. The pull-twist 19 passes through the outer surface of the plate, and the pull-twist 19 is a T-shaped structure. A spring B20 is sleeved on the surface of the pull-twist 19, and the spring B20 is placed on the inner side of the storage hole 17. One end of the spring B20 contacts the end surface of the wedge block 18. The elastic force of the spring B20 allows the wedge block 18 to always cooperate with the ratchet disk 16 when not subject to external force, thereby ensuring that the control shaft 13 can only rotate in a single direction, and realizing real-time limiting during festivals.

[0028] Working principle: The traction part 4 at the front end is used to realize the movement of the device. After it moves into place, the knob 15 can be rotated to drive the elliptical extrusion disk 14 to rotate. The cooperation of the wedge block 18 and the ratchet disk 16 can realize that the control shaft 13 can only rotate in a single direction. The extrusion heads 11 on both sides are squeezed by the change of the major and minor axes of the elliptical extrusion disk 14. The spring A12 is squeezed and stored. The two slide bars 10 on the same side are separated from each other, and the extrusion plate 8 is squeezed, so that the fastening ring 7 is tightened to limit the rotating shaft 5 to prevent the roller 6 from moving during operation and ensure the stability of the device during operation. When it is necessary to move, the external pulling and twisting 19 can be used to make the wedge block 18 no longer cooperate with the ratchet disk 16. At this time, the control shaft 13 and the ratchet disk 16 can be driven to rotate in the opposite direction, and then the extrusion head 11 is no longer squeezed. The stored force of the spring A12 is used to make the two extrusion heads 11 close to each other, and the slide bar 10 no longer squeezes the extrusion plate 8. At this time, the rotating shaft 5 can rotate freely.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
