Description

Technical Field

[0001] The utility model belongs to the field of cone crushers, and particularly relates to a feeding device for cone crushers. Background Art

[0002] Cone crushers are widely used in mining, construction, and metallurgy to crush various ores and rocks into smaller particles. Their primary operating principle is to utilize a crushing cone between a stationary liner and a moving cone to crush the rock. The increasing demand for construction projects is placing higher demands on high-performance, low-energy crushing equipment. Especially when processing high-hardness rocks such as basalt, equipment performance, durability, and energy efficiency are crucial.

[0003] For example, Chinese patent CN 216654892U discloses a cone crusher, which includes a crusher assembly, a material distribution assembly installed inside the crusher assembly, and the material distribution assembly includes a support rod, a material distribution plate, a support column and a fixed groove. The outer surface of the support rod is installed with a material distribution plate, the inner side wall of the material distribution plate is fixedly connected to the support column, and the bottom end of the support column is movably connected to the fixed groove.

[0004] In this cone crusher, the distribution plate is fixed and the size of the discharge channel cannot be controlled according to the size of the crushed material. When the crushed material particles are large, the crushed material is likely to accumulate above the distribution plate; when the crushed material particles are small, it is easy to cause overfeeding, resulting in reduced crushing efficiency and uneven particle size of the crushed material.

[0005] Therefore, we propose a feeding device for cone crusher to solve the above problems. Utility Model Content

[0008] The conical seat is arranged in the barrel and is fixed to the inner wall of the barrel through a plurality of support arms. A mounting rod is fixedly installed at the bottom of the conical seat.

[0009] Four sets of material guide units are arranged around the bottom of the conical seat. The material guide units include a material guide plate and a hydraulic rod. The upper end of the material guide plate is hinged to the bottom of the conical seat. There is a gap between the material guide plate and the inner wall of the barrel to form a material discharge channel.

[0010] The hydraulic rod is hingedly installed between the mounting rod and the guide plate.

[0011] Preferably, the top view of the conical seat is rectangular.

[0012] Preferably, it further comprises N groups of clamps, which are installed at the bottom of the barrel and connected to the feed port of the cone crusher.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See also Figure 1-2 The utility model provides a technical solution for a feeding device for a cone crusher:

[0022] Example 1:

[0023] according to Figure 1 and Figure 2As shown, it includes a barrel 1, a conical seat 2 and four sets of material guide units. The top and bottom of the barrel 1 are open, and the bottom end can be detachably installed at the feed port of the cone crusher.

[0024] The top view of the conical seat 2 is rectangular. The conical seat 2 is arranged in the barrel 1 and is fixed to the inner wall of the barrel 1 through a number of support arms 3. By setting the conical seat 2, the crushed material slides to the surroundings under the guidance of the conical seat 2, avoiding blockage of the crushed material.

[0025] A mounting rod 5 is fixedly mounted on the bottom of the conical seat 2 , and four groups of lug plates 7 are fixedly mounted on the bottom of the conical seat 2 , with each group of lug plates 7 having two.

[0026] Four groups of guide units are arranged around the bottom of the conical seat 2. The guide units include a guide plate 6 and a hydraulic rod 82. The upper end of the guide plate 6 is hingedly installed between the two ear plates 7 through a hinge shaft, so that the guide plate 6 can move. There is a gap between the guide plate 6 and the inner wall of the barrel 1 to form a discharge channel, so that the crushed material falls evenly into the crushing chamber of the cone crusher through the discharge channel.

[0027] The two ends of the hydraulic rod 82 are hinged to the upper hinge seat 83 and the lower hinge seat 81 respectively through a pin shaft. The lower hinge seat 81 is fixedly mounted on the side of the mounting rod 5, and the upper hinge seat 83 is fixedly mounted on the side of the guide plate 6. By controlling the extension and contraction of the hydraulic rod 82, the inclination angle of the guide plate 6 is adjusted, and then the discharge channel can be adjusted according to the size of the crushed material to control the discharge speed.

[0028] In specific use, the utility model is a feeding device for a cone crusher. First, according to the size of the crushed material, the four hydraulic rods 82 are controlled to extend and retract synchronously. When the hydraulic rods 82 are extended and retracted, the inclination angle of the guide plate 6 is adjusted, and the material discharge channel is adjusted at the same time.

[0029] After the adjustment of the surrounding discharge channels is completed, the crushed material enters the barrel and, under the guidance of the conical seat 2, slides into the surrounding discharge channels and falls into the crushing chamber of the cone crusher through the discharge channels for crushing.

[0030] Example 2:

[0031] Based on the first embodiment, Figure 1 and Figure 2 As shown, it also includes N groups of clamps, which are arranged at the bottom of the barrel 1.

[0032] The fixture includes an L-shaped plate 41, a movable clamping plate 42 and a fixed clamping plate 43. The fixed clamping plate 43 is welded to the bottom of the inner wall of the barrel 1. One end of the L-shaped plate 41 is welded to the outer side of the barrel 1. The threaded hole opened in the L-shaped plate 41 is threadedly connected to an adjusting bolt 44. A bearing is installed on the optical axis of the inner end of the adjusting bolt 44, and the bearing is installed on the movable clamping plate 42.

[0033] By docking the barrel 1 with the feed port of the cone crusher, the movable clamping plate 42 is moved toward the fixed clamping plate 43 by rotating the adjusting bolt 44, and then the barrel 1 is detachably installed at the feed port of the cone crusher through the cooperation of the movable clamping plate 42 and the fixed clamping plate 43.
