Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher device, and more particularly to a crusher device capable of finely crushing a crushed material obtained by crushing an object to be processed with crushing blades.

2. Description of the Related Art A screw press apparatus is generally used to squeeze juice from a water-containing object to be processed, such as fruit, or to dehydrate water from vegetables. A screw press apparatus guides a material to be processed by a rotating screw and dehydrates the material by applying pressure with a screw blade. There are two types of screw press machines: a vertical type in which the screw blades are arranged vertically and a horizontal type in which the screw blades are arranged horizontally.

For example, since spherical fruits such as apples and spherical vegetables such as cabbage and onions cannot be put into the screw press as they are, they need to be first crushed by a crusher or the like. As the crusher device, for example, in addition to the one shown in Patent Document 1, those having various configurations are provided. As a conventional vertical crusher device used before dehydration of vegetables and fruits, for example, a crushing blade in which a coarse crushing blade is arranged at the top and a fine crushing blade is arranged at the bottom, and a lower part of the crushing blade It is known to have a screw blade located at the bottom of the screw blade and a discharge blade located below the screw blade.

As shown in FIG. 2, the upper-stage input hopper 2A and the lower-stage input hopper 2B are connected to each other, and as shown in FIG. there is Therefore, by rotating the hoppers 2A and 2B about the rotation shaft 31, the user can move the hoppers 2A and 2B between the input position above the opening of the fixed blade housing 3 and the retracted position outside the opening above the opening. can be moved.

The crushing blades 13 are arranged on the upper side and are rotary blades 13A (FIG. 3), which are rotating blades rotating around the rotating shaft 21, and are arranged on the lower side and are rotating blades rotating around the rotating shaft 21. The gap between the fine crushing blade 13B and the fixed blade 3B (FIG. 4) is larger than the gap between the coarse crushing blade 13A and the fixed blade 3B (FIG. 3). set small. These coarse crushing blades 13A and fine crushing blades 13B cooperate with a plurality of fixed blades 3B, 3B, . . . crush the For example, the objects to be crushed falling from the upper input hopper 2A and the lower input hopper 2B are roughly crushed by the coarse crushing blades 13A to become crushed objects (coarsely crushed objects) having a size of 3 to 10 mm. After falling to the bottom, it is finely crushed by the finely crushing blade 13B to become crushed objects (finely crushed objects) of 2 to 3 mm in size and further dropped downward.

The crushing blade 16A is a rotating blade that further finely crushes the crushed material obtained by crushing the object to be processed by the crushing blade 13 (FIG. 5). The crushing blade 16A is attached to the rotating shaft 21 coaxially with the crushing blade 13 on the lower side of the crushing blade 13. A plurality of fixed blades 3B, In cooperation with 3B, . The crushed material falling from the side of the crushing blade 13 is crushed by the crushing blade 16A to become crushed material having a size of 0.5 to 1.0 mm and further falls downward.

The raw material through control plate 16B is arranged below the grinding blade 16A, and is a rotating plate that guides the crushed material obtained by crushing the material to be crushed by the crushing blade 13 to the gap between the grinding blade 16A and the fixed blade 3B. is. The raw material slew control plate 16B is arranged coaxially with the grinding blade 16A on the rotating shaft 21, and is formed so that the peripheral edge portion is wavy in a plan view. Eight protruding portions 16B1, 16B1, . A curved inclined surface is formed between the portions 16B1, 16B1, . . . and the separation portions 16B2, 16B2, . That is, the raw material slew control plate 16B has a substantially ratchet gear shape in which the teeth are arranged so as to be inclined with respect to the rotation direction (FIG. 5). As a result, the crushed material falling below the crushing blade 13 is temporarily held on the plate surface of the raw material through control plate 16B, moved toward the inner peripheral wall portion 3A by the centrifugal force of the raw material through control plate 16B, and ground. It is guided to the gap between the crushing blade 16A and the fixed blade 3B.
