[0003] The feeding mode of Sandvik can cause the following problems of the crusher;One, uneven distribution of material causes local load of the crusher, and the pressure increases instantaneously, so the high-pressure oil pipe is frequently impacted by load, leading to pipe explosion, affecting the service life of high-pressure oil pipe and normal operation of equipment.Two, one-side feeding causes local wear of fixed cone lining plate to increase, leading to premature failure of fixed cone lining plate, affecting the service life of lining plate and increasing the operation and maintenance cost of the crusher.Three, partial load operation of the crusher increases the operation load of the crusher, leading to increased operation energy consumption of the crusher, and if the local load is too large, the crusher may even be stuck, which is not conducive to normal production. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at solving the above-mentioned series of problems caused by uneven distribution of material, and provides a uniform material distributing device of cone crusher without distributing disc, which realizes uniform material distribution through self-rotation of the material distributing device.

[0006] Preferably, the discharge ports are symmetrically opened in four along the axis.

[0007] Further, the lower support is wider than the outer contour size of the arm frame guard plate.

[0008] Further, the motor is electrically connected with a frequency converter.

[0009] Furthermore, the diameter of the distribution plate is larger than the outer contour dimension of the boom cap.

[0014] like Figure 1 , 2 A uniform material distribution device for a cone crusher includes a cross brace 11 fixed to the inner wall of the dust hopper of the feeding belt. An upper support 6 is welded and fixed to the cross brace 11. The upper support 6 is a steel plate frame with four sides: top, bottom, left, and right. A cycloidal pinwheel reducer 2 is bolted to the upper support 6, and the cycloidal pinwheel reducer 2 is connected to a motor 1. The output end of the cycloidal pinwheel reducer 2 passes downward through the upper panel of the upper support 6 and is connected to a rotating shaft 4 via a flexible pin coupling 3. When the motor 1 starts, it drives the rotating shaft 4 to rotate via the cycloidal pinwheel reducer 2 and the flexible pin coupling 3.

[0015] The rotating shaft 4 is vertical, passes through the upper support 6, and is fixed to the upper support 6 with an upper bearing seat 5. The upper part of the rotating shaft 4 is rotatably supported by the upper bearing seat 5. A material distribution plate 7 is welded to the lower part of the rotating shaft 4. The material distribution plate 7 has four symmetrical discharge ports 71 along the axis. The material distribution plate 7 is located below the material drop point and above the boom cap 12. The bottom of the rotating shaft 4 is rotatably connected to the lower bearing seat 8, which supports the bottom of the rotating shaft 4 and allows it to rotate. The lower bearing seat 8 is fixed to the lower support 9. The lower support 9 is inverted U-shaped, spans the boom cap 12, and its bottom ends are welded and fixed to the boom guard plate 10.

[0016] A uniform material distribution device for a cone crusher, characterized in that: the lower support 9 is wider than the outer contour dimension of the boom guard plate 10, which can protect the boom guard plate.

[0017] The feeding conveyor belt has displacement phenomenon, so the motor 1 is electrically connected with the frequency converter. The motor forward rotation / reverse rotation can be controlled through the frequency converter to realize the material front and back movement caused by the feeding belt displacement, so that the stone falls as much as possible on the distribution disc 7, and the frequency can be adjusted to realize the same crushing frequency as the crusher. The material size change can be realized by adjusting the frequency converter frequency to realize uniform material distribution.

[0018] The diameter of the distribution disc 7 is greater than the outer contour size of the arm support cap 12, and the stone is thrown out by the centrifugal force of the distribution disc 7, and does not directly hit the arm support cap 12.

[0019] The operation of the device: the material enters the distribution disc 7 through the feeding belt, the motor 1 drives the rotating shaft to rotate through the elastic column pin shaft coupling 3 connection rotating shaft 4, drives the distribution disc 7 to uniformly distribute the material around the crushing chamber of the cone crusher. The utility model has the advantages of simple structure, compactness and reasonableness, which solves the feeding segregation phenomenon caused by feeding, improves the use performance of the cone crusher, improves the production efficiency, prolongs the service life of the main machine and the spare parts, and effectively reduces the operation and maintenance cost of the crusher.
