Description

[Detailed Description of the Invention] The present invention relates to an apparatus for evenly feeding raw materials in a crusher. In conventional devices of this kind, a tilting table for rotating and evenly feeding raw materials, such as stones, dropped from a hopper to a crusher was rotationally driven via a special motor, a V-belt, and the like. However, such a method requires electricity for driving the motor and also requires a motor control panel, which has the disadvantage that the entire device becomes expensive. Further, during operation, the V-belt easily comes off or is easily cut by stones, sand, dust, etc., and maintenance is time-consuming.

The present invention has been developed in view of the above points, and it is possible to use the rotational driving force of the main shaft of the crusher main body to operate the tilt table without requiring a special motor, etc., thereby solving the drawbacks of conventional devices. The aim is to eliminate all of these issues.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

The drawing is a vertical sectional view of an embodiment of the present invention,
Reference numeral 1 represents a cap that is connected to the bottom of a casing 3, which will be described later, and 2 represents a main shaft of the crusher main body, which reciprocates in the vertical direction while rotating. 3 is a casing to which the cap 1 is connected at the bottom. 4 is a bearing provided between the inner surface of the casing 3 and the outer surface of a cylindrical shaft 8, which will be described later. 5 is a bearing provided between the inner surface of the casing 3 and the outer surface of the cylindrical shaft 14 described later. 6 is the main shaft 2 of the crusher main body
This is a universal joint in which one side is connected to the upper end of the shaft and the other side is connected to the spline shaft 7. Reference numeral 7 denotes a spline shaft connected to the universal joint 6, and is provided in a vertical position. A cylindrical shaft 8 rotates outside the universal joint 6, and a boss 9 of the spline shaft 7 is provided at the upper end. 10 is a large bevel gear fixed to the upper outer periphery of the cylindrical shaft 8;
It rotates in the horizontal direction due to the rotation of .
Reference numerals 11 and 11 designate small bevel gears that mesh with the large bevel gear 10, and are rotatably supported on the inner surface of the casing 3 with a shaft 12. 13 is a large bevel gear that meshes with the small bevel gears 11, 11;
a cylindrical shaft 14 rotating outside the spline shaft 7;
is fixed to the lower end of the 15 is the cylindrical shaft 1
This is a support stand fixed to the upper end of 4. Reference numeral 16 denotes an inclined table mounted on and fixed to the support table 15 for evenly supplying raw materials. Additionally, 17 indicates a hopper.

Next, the operation mode of the present invention having the above configuration will be explained.

When the main shaft 2 of the crusher body rotates, the spline shaft 7 rotates via the universal joint 6. As the spline shaft 7 rotates, the cylindrical shaft 8 rotates via the boss 9, and the large bevel gear 10 fixed thereto also rotates. A small bevel gear 1 meshes with the large bevel gear 10 as it rotates.
1 and 11 rotate, and further the small bevel gears 11 and 11
The large bevel gear 13 that meshes with also rotates. Note that the rotation in this case is in the opposite direction to that of the large bevel gear 10. Further, as the large bevel gear 13 rotates, the cylindrical shaft 14 rotates, and the tilt table 16 rotates via the support table 15. Therefore, raw materials such as stones (not shown) fall from the hopper 17.
is evenly supplied to the crusher by means of a tilting table 16 which rotates in the opposite direction to the main shaft 2 of the crusher body.

The main shaft 2 of the crusher main body reciprocates in the vertical direction while rotating, but since it is connected via a spline shaft 7, the rotational force is transmitted without any problem.

Since the present invention has the above-described structure and operation, it is possible to rotate the inclined table for uniformly supplying raw materials by using the rotational force of the main shaft of the crusher main body. Therefore, unlike conventional devices, there is no need for a special motor and its control panel, and accidents such as V-belt breakage can be avoided, which is extremely advantageous in terms of manufacturing costs and maintenance management. This is extremely effective in practice.
