Description

[Detailed description of the invention] This invention uses a rotor with striking blades arranged at regular intervals in the axial direction inside an ice-breaking chamber surrounded by a chute on one side and provided with an inlet and an outlet for ice blocks. The chute is rotatably supported, and the lower part of the chute is provided with a comb-shaped receiving tooth on the side surface through which the striking blade passes, and the ice cubes introduced into the ice crushing chamber from the input port are chuteed by the rotation of the rotor and the striking blade. pressed against
In an ice crusher that uses a striking blade that passes between the receiving teeth to crush the ice and discharge it from the outlet, the roughness of the cutting water cannot be changed because the forming interval of the receiving teeth remains unchanged, but this can be adjusted using an adjustment plate. The receiving tooth is formed at a large interval through which two of the adjacent striking blades pass, and the side part of the receiving tooth is formed as it moves from the lower position to the upper position. A shaft support for an adjustment plate provided with a plurality of protrusions forming a small interval through which the striking blades pass one by one in cooperation with the receiving teeth, and the adjustment plate is moved upwardly. This is characterized by the attachment of a cam that locks in position, and the adjustment plate is locked in the upper position by the cam, allowing fine adjustment of the ice crushing roughness, which is normally unchanged. The purpose is to

A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a machine frame supported by pillars 3 set up at the four corners of a base plate 2. A chute 4 inclined at an angle of about 60' is fixed inside the frame, and an ice-breaking chamber 7 surrounded on one side by the chute 4. is formed to provide an input port 8 and a discharge port 9, and a container 22 can be inserted into the lower part of the discharge port 9.

The chute 4 is provided with a curve 5 at the lower end, and the distal end surface of the curve is shaped like a comb to form a plurality of curved receiving teeth 6, 6, which project directly above the discharge port 9.

(Figures 1 and 3). The chute 4 is curved 5 by arranging a plurality of retaining ridges a to e at regular intervals in the width direction on its surface.
In this case, the receiving teeth 6, 6 are formed so as to form an extended shape at the tip of the ridge d.

In the ice-breaking chamber 7, a rotor 11 is fixed to a shaft 10 rotatably supported on its side wall, and a striking blade 13 sharpened in the rotational direction is attached to a large number of protrusions 12 provided on the outer periphery of the rotor.

The striking blades 13 are spaced at regular intervals in the axial direction and arranged in a spiral shape in the rotational direction.

The receiving teeth 6 provided on the chute 4 are close to the lower outer periphery of the rotor 11 and extend directly below the shaft 10, and these receiving teeth 6, 6 are connected to two adjacent central portions. It is formed to have a large interval through which the striking blades 13 are rotated.

The two outer striking blades 13 pass between each outer side of the receiving teeth 6, 6 and the inner surface of the side wall of the ice-breaking chamber 7.

In some cases, the impact blades 13 13 are arranged in pairs in the axial direction, passing between the receiving teeth 6 and the outside thereof.

Below the tip of the chute 4, an adjustment plate 15 is passed through an axle 14 which is fixed through the side wall of the machine frame 1, and is freely rotatably supported. The cam 19 is attached to the shaft rod 18 supported through the shaft.

The cam 19 can be rotated by approximately 1800 degrees by a knob fixed to the shaft rod 18 on the outside of the machine frame 1, and support surfaces 20 and 21 are provided at two positions thereof.

The adjustment plate 15 has a cam contact surface 16 extending rearward from the shaft 14, and the contact surface 16 is connected to the support surface 20 or 21 of the cam.
The receiving tooth 6, which is in front of the shaft 14, can be moved to either the lower position in FIG. 1 or the upper position in FIG. 2 by contacting the shaft 14 from below. Corresponding protrusions 17, 17.17 are provided between the receiving teeth on both sides and the inner surface of each side wall of the ice-breaking chamber 7.

When the adjusting plate 15 is moved to the upper position in FIG.
protrudes between the inner surface of the side wall of the
The projection is made to be the same as the upper surface 6a of the blade, and together with the receiving teeth 6, 6 forms a small interval L' having an equal interval through which one striking blade 13 passes.

The other 23 is a motor installed on the base plate 2, which drives a pulley 25 attached to the shaft 10 outside the ice-breaking chamber 7 via a speed reduction mechanism 24 to drive the rotor 11 in the arrow direction in FIG. do.

In this embodiment, when the cam abutment surface 16 of the adjustment plate 15 is received by the support surface 20 of the cam 19 and each projection piece 17 is placed in the lower position retracted below the receiving tooth 6 as shown in FIG. Between the teeth 6 and 6 and between one of the receiving teeth and the inner surface of the side wall of the ice-breaking chamber, a large gap is formed through which two adjacent striking blades 13 are passed, and from the input port 8 into the ice-breaking chamber 7. The water force ′ pressed against the chute 4 by the rotation of the rotor 11 is crushed to a roughness of, for example, 2 mm corresponding to the above-mentioned spacing, and the ice blocks a are moved downward according to the crushing and are discharged from the outlet 9 into the container 22 .
Drop crushed ice onto the ground.

Also, rotate the cam 19 by about 180 degrees, contact the cam contact surface 16 from below the support surface 21, and adjust the adjustment plate 1 as shown in FIG.
When the protruding pieces 17 of 5 are placed in the upper position, these protruding pieces protrude between the receiving teeth 6 and between the receiving teeth 6 and the inner surface of the side wall of the ice-breaking chamber 7, and together with the receiving teeth, the small distance L' is created. , and one striking blade 13 is passed through each small interval L'.

Therefore, the ice block a' in contact with the chute 4 is crushed to a roughness of, for example, 1 cm, which corresponds to the small distance L', and falls into the container 22.

When the chute 4 is provided with engagement protrusions a to e, when the adjustment plate 15 is in the upper position, the receiving teeth 6°6 and the protrusions 17,
17, 17 are located at the extensions of these protrusions a''e.

Each of the protrusions a''-e melts and engages the ice block a' that is supplied from the input port 8 and comes into contact with the chute 4, thereby preventing it from moving to the left or right, and the striking blade This prevents fluctuations due to the reaction force of crushing caused by 13.

When the adjustment plate 15 is in the downward position, broken water that is broken at large intervals and falls into the container 22 hits the protrusion 17 and slides down, which may cause vibration, but the cam 1
When the buffer spring is slightly protruded from the support surface 20 of 9 or in the downward position, the buffer spring is brought into contact with the cam contact surface 16, and when the buffer spring is compressed, the cam contact surface 16 abuts against the support surface 20. It can also reduce shock.

As clarified by the above description, the present invention protrudes the projecting piece 17 of the adjusting plate 15 that has been moved to the upper position between and outside the receiving teeth 6 of the chute 4, which have a large interval that cannot be changed. In cooperation with the receiving teeth 6, small intervals L' are formed, and the striking blades 13 of the rotor 11 are rotated to pass through each of the small intervals L'. , the ice block sliding down in contact with the chute 4 can be crushed to a roughness corresponding to a large interval, or by moving the adjustment plate 15 to an upper position, it can be crushed to a roughness corresponding to a small interval L'.

Further, since the adjustment plate 15 is supported by the cam 19 when forming the small interval L', it can have strength to withstand the impact of crushed ice, and has the effect of arbitrarily adjusting the roughness of crushed ice.
