[Prior art]

  For example, at fishing ports, a large amount of flaky ice (hereinafter referred to as “flake ice”) is used to catch fish. It is common to store things frozen, and flake ice is vigorous for this purpose. There is a great demand. Flake ice is generally formed on the inner wall of a cylindrical frozen casing. It is obtained by freezing ice in layers and scraping this ice layer with a peeling blade. This is because a large amount of this is accumulated and stored in the ice storage, and the screw installed at the bottom of the storage The required amount of ice is carried out of the refrigerator.

[0003]   Here, flake ice is a physical property of ice, which is a fusible solid, and crystal particles are agglomerated. It has a phenomenon of solidifying and clumping (caking). Also, a large amount of flake ice accumulation There is a tendency to bridge (arch) inside the ice storage, which causes flare from the bottom of the ice storage. While the ice is carried out by the screw, it is internally arched to create a cavity, then It makes it extremely difficult to carry out flake ice from outside.

[0004]   In this way, flake ice clumps and arches in the ice storage, As means for coping with the phenomenon that it is difficult to carry out the flake ice, FIG. 3 and FIG. An ice storage with the structure shown is proposed. In other words, the ice box with a box shape A space 12 capable of accumulating and storing a large amount of flake ice to a predetermined level is imaged inside the interior of 10. Is made. This space 12 is an ice storage space 12a by a crusher 16 described later. And an ice carry-out space 12b, and a slat container is provided at the bottom of the ice storage space 12a. The yarn 15 is arranged so that it can travel freely. In addition, flake ice production is provided on the top of the ice storage 10. The flake ice produced by the machine 13 is mounted on the flake ice through the chute 14. It is dropped and discharged into the storage space 12a. The outer surface of the side wall of the ice storage 10 is covered with a heat insulating material. Then, the inside of the ice storage 10 is forcibly cooled by a refrigeration unit (neither is shown). It is like this.

[0005]   As shown in FIG. 3, the slat conveyor 15 is provided on the upper part on the downstream side in the traveling direction. The space 12 is divided into an ice storage space 12a and an ice discharge space 12b, and Crusher 1 that functions to scrape the flake ice groups 11 accumulated in the space 12a 6 are provided. As shown in FIG. 4, the crusher 16 is a slat controller. The rotatable shaft 17 extending in the direction intersecting the traveling direction of the bayer 15 has a large number of Place the rectangular crusher body 19 in which the protruding pins 18 are planted in an appropriate arrangement in the vertical direction. A plurality of stages are arranged at regular intervals. Also, at the bottom of the ice unloading space 12b side The screw conveyor 20 is rotatably arranged, and the screw conveyor 20 is discharged into the space 12b. The lake ice was opened on the side wall of the ice storage 10 by the screw conveyor 20. It is designed to be carried out of the refrigerator via the mouth 21.

[0006]   That is, the flake ice produced by the production machine 13 is stored in the ice storage as shown in FIG. It is discharged and stored on the slat conveyor 15 arranged in the retaining space 12a, and is accumulated here. The resulting flake ice solidifies to each other and agglomerates. Large flake ice group 1 1 is conveyed toward the crusher 16 as the slat conveyor 15 travels. It At this time, each rectangular crusher body 19 that constitutes the crusher 16 is forcibly rotated. By doing so, the flake ice group 11 is sequentially scraped from the downstream side in the traveling direction and ice is It is discharged to the carry-out space 12b. And the flake ice that was crushed is It is carried out of the warehouse by the conveyor 20.

[0007]

[Problems to be solved by the device]

  The rectangular crusher body 19 constituting the crusher 16 has a large number of rotary shafts 17. Since a large number of projecting pins 18 are planted, the flake ice is carried out from the ice storage 10. When the operation is continued for a long time, as shown in FIG. 5, the adjacent protruding pins 18 are provided. The phenomenon that flake ice adheres between them occurs. In this case, The flake ice group 11 is not scraped (so-called "idle operation") and the ice is taken out. The release of flake ice into the space 12b is stopped, and the screw conveyor 20 is used. There was a drawback that the flake ice would not be carried out. Also due to this Then, the subsequent flake ice group 11 is moved by the slat conveyor 15 and the crusher 1 is moved. 6, the rotating shaft 17 of the rectangular crusher body 19 is deformed or damaged. There was a serious problem to do. Moreover, this phenomenon is caused by the traveling of the slat conveyor 15 and Also, the rotation of the rectangular crusher body 19 is impaired, and the slat conveyor 15 and the rack It is also pointed out that the drive motor (not shown) of the lasher 16 gives an excessive load. .

[0008]   Further, when the crusher 16 is stopped, each square crusher is The ice storage space 1 is provided between the projecting pins 18, 18 projecting from the body 19 and adjacent in the axial direction. Inevitably a gap is created that connects the 2a and the ice unloading space 12b (see FIG. 4). others Therefore, the flake ice produced by the flake ice making machine 13 is accumulated in the ice storage space 12a. At the time of storage, a part of the flake ice accumulated in a mountain shape on the slat conveyor 15 is in front. From the gap, spill into the ice unloading space 12b, or carry out the required amount of flake ice. After the crusher 16 is stopped, the flake ice in the ice storage space 12a will not leave a gap. There was a drawback that the ice spilled into the ice carry-out space 12b via the.
