TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a vibrating sand crusher.
[0002]
[Prior art]
Conventionally, as one type of a vibrating sand lump crusher of this kind, a box-shaped lump storage tank having a space capable of storing lump is elastically supported, and the lump storage tank is vertically or diagonally moved up and down. There is one that vibrates in a vertical direction or vibrates a sand mass in a sand mass storage tank in a vertical direction or an oblique vertical direction (see Patent Literature 1).
[0003]
[Patent Document 1]
JP-A-57-116366.
[Problems to be solved by the invention]
However, the conventional vibratory sand crusher configured as above requires a large vibration motor for vibrating the sand storage tank, and accordingly, the conventional vibratory sand crusher is large. In addition to being expensive, there was a problem that a large installation space was required and the pit became deep.
[0005]
The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a vibrating sand crusher capable of reducing the size of a vibration motor for vibrating a sand storage tank. is there.
[0006]
[Means to solve the problem]
In order to achieve the above object, the vibratory sand lump crushing device of the present invention is a device for crushing sand lump, a sand lump storage tank having a structure capable of storing sand lump and elastically supported, An inner tank having a large number of holes through which sand particles can be mounted and formed with an appropriate gap between the inner surface of the sand lump storage tank and a sand lump storage tank, and an unbalanced weight mounted on the outer surface of the sand lump storage tank. An unbalanced weight type vibrating means for vibrating the sand mass storage tank and the internal tank so that the Lissajous figure draws a substantially circular shape by rotation.
[0007]
With this configuration, when the unbalanced weight type vibrating means is driven after approximately a predetermined amount of sand mass to be crushed is put into the internal tank, the sand mass storage tank and the internal tank have a substantially circular Lissajous figure. Vibrating as if drawing, vibrations in two directions, horizontal and vertical, are applied to the sand mass. Along with this, the sand lumps are efficiently crushed into sand particles, and then fall from the holes onto the bottom plate of the sand lumps storage tank, and are discharged from the chute through the discharge holes.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 which is a front view. The vibrating sand lump crushing apparatus is provided with a sand lump storage tank 1 having a box shape capable of storing sand lump and elastically supported, and forming an appropriate gap between the inner surface of the sand lump storage tank 1 and the inside thereof. And an inner tank 3 having a number of slit-shaped holes 2 and 2 through which sand particles can penetrate, and is mounted on the outer surface of the sand lump storage tank 1, and the Lissajous figure is substantially circular by rotation of the unbalance weight. And an unbalance weight type vibrating means 4 for vibrating the sand lump storage tank 1 and the internal tank 3 as depicted.
[0009]
The sand lump storage tank 1 is installed on a frame 6 via a plurality of air springs 5.5. Further, a chute 7 communicating with a sand particle outlet (not shown) is provided below the sand lump storage tank 1.
[0010]
In the unbalance weight type vibrating means 4, two vibrating motors 8, 8 are mounted on both left and right sides of the sand lump storage tank 1 with their rotating shafts positioned on the same line. The axis of rotation of the motors 8 passes through the center of gravity of a vibrating object composed of the sand lump storage tank 1, the internal tank 3, and the sand lump stored in the internal tank 3. 8 is such that the unbalance weight rotates at the same speed in the same direction. Therefore, by the rotation of the unbalance weight, the sand lump storage tank 1 and the internal tank 3 are vibrated so that the Lissajous figure draws a substantially circular shape, and sand particles and the like can be transferred in a predetermined direction. It has become.
[0011]
In the above-described structure, after a predetermined amount of the sand mass to be ground is put into the inner tank 3, the two vibration motors 8.8 are driven in the forward direction, and the two pairs of unbalanced weights are moved in the predetermined direction. When rotated at a constant speed (forward rotation), the sand lump storage tank 1 and the internal tank 3 are vibrated so that the Lissajous figure draws a substantially circular shape.
[0012]
As a result, vibrations in two directions, a horizontal direction and a vertical direction, are applied to the sand lumps in the inner tank 3, whereby the sand lumps are efficiently crushed into sand particles, and then the holes 2. 2 falls on the bottom plate of the sand lump storage tank 1 and is discharged from the chute 7 through the discharge hole.
[0013]
Table 1 shows, for reference, data comparing the crushing performance of the vibrating sand crusher with a circular vibration according to the present invention and the conventional vibrating sand crusher with a longitudinal vibration.
[0014]
[Table 1]

From Table 1, it can be seen that the vibratory sand crusher of the present invention has almost twice the processing capacity of the conventional vibratory sand crusher. In other words, the vibration motor of the vibratory sand crusher of the present invention requires only half the capacity of the conventional vibratory sand crusher.
[0015]
【The invention's effect】
As is clear from the above description, the present invention is an apparatus for crushing a sand lump, a sand lump storage tank having a structure capable of storing the sand lump and elastically supported, and a sand lump storage tank in the sand lump storage tank. An inner tank having a plurality of holes through which sand particles can be inserted and formed with an appropriate gap formed between the inner surface thereof and an outer surface of the sand mass storage tank, and a Lissajous figure is substantially formed by rotation of an unbalanced weight. Since it is provided with an unbalanced weight type vibrating means for vibrating the sand lump storage tank and the internal tank so as to draw a circle, the vibration motor for vibrating the sand lump storage tank can be downsized. It has a practical effect.
