Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of requiring an inexpensive method to return to a snow shape, since snow-shaped seawater ice becomes a large snow ice mass by consolidating in a vessel when transporting the snow-shaped seawater ice to a distant place, though a demand of the snow-shaped seawater ice increases as a raw material of seawater sherbet being a coolant of raw fish. <P>SOLUTION: A recess-projection is arranged in an inclined part of an angle-shaped tool with the lateral width center as a top part, and is also bent in a " V " shape in a central part. In a snow shaving machine, the snow ice mass is scratched off from a surface in this recess-projection part, and a scratched-off snow ice piece is crushed by a rotary blade. A door for carrying in the snow ice mass is arranged in this ice shaving device, and an L-shaped carrying-in stage is also added, and the upper side of the door and an upper piece of the carrying-in stage, and also the lower side of the door and the contour of the ice shaving device, are respectively rotatably joined. Thus, an emptied vessel is returned to an original carrying-in stage position by sending out the inside snow ice mass in the device by automatically overturning the vessel lowered on the carrying-in stage only by opening-closing operation of a carrying-in door. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a device for returning a snowy ice block formed by solidifying snowy seawater ice in a transport container to snowy ice.

  Since the commercial value of fresh foods depends greatly on the freshness, refrigerated storage is essential. Fishes that are particularly susceptible to loss of freshness are cooled by putting a large amount of fresh water ice in the seawater in the hold immediately after capture. Even from the market to the point of demand, spread ice on the fish and sprinkle the seawater with a hose. Transported. However, because the area of the fish that is in direct contact with the cracked ice is small, the freshness was likely to decline early.

  Recently, seawater sherbet ice has attracted attention as an improvement measure. Fish is immersed and transported in sherbet-like ice, which is a mixture of fine snow-like ice made from seawater and seawater. Because the ice particles are fine, the entire sherbet has a uniform temperature, and the fish body is softly surrounded so that it is evenly cooled. It has the characteristics of

  Conventionally, snowy sea ice produced at an ice making factory near a fishing port is transported to a fishing port or a market in a dedicated container and mixed with sea water. As a container for snowy sea ice, for example, a synthetic resin container having a width, height of 1 m, and length of about 2 m is used, and a forklift is used for loading and unloading.

  As the advantages of seawater sherbet ice became clear, the demand for snowy sea ice from remote fishing ports and markets also increased. However, it was found that when snowy sea ice was transported to a remote location, it would harden in the container, resulting in a large-sized snow ice mass of container size. In order to use this as seawater sherbet ice, it must be subdivided and returned to snowy ice.

  The conventional ice lump subdivision methods are roughly divided into a crushing method and a cutting method.

  Examples of the crushing device include a device that strikes and breaks as disclosed in JP-A-8-54166, and a device that crushes with a sharp blade as disclosed in JP-A-6-331247. In the former Japanese Patent Laid-Open No. 8-54166, small ice cubes are thrown between two rotating cylinders provided with a large number of striking teeth so as to be crushed. In order to use this method for crushing large snow ice blocks, a huge rotating cylinder is required, and high equipment and operating costs must be borne.

  In an attempt, a forklift was used to raise the snow and ice mass to a height of about 2 m, and a drop test was carried out. However, it could not be crushed because only a part of the surface was missing.

  The method of swinging and thrusting the ice breaking blade disclosed in JP-A-6-331247 greatly increases the equipment. As a test, a large snow ice block was abutted against a thick iron bar with a sharpened tip, but it was found that the iron bar was buried in the snow ice mass and could not be expected to break.

  Such a sticky property that does not break due to impact force is a point that is significantly different from normal fresh water ice. This is probably because adjacent particles of ice are connected to form a mesh structure, and even if cracks occur on the surface, the progress is prevented at the ice particle portion, which is a node.

  The cutting method cuts the surface of hard ice using a blade. For example, Japanese Utility Model Laid-Open No. 01-041062 is a miscellaneous ice removing device in which a large number of circular blades are arranged in a spiral shape around the entire circumference of a rotating cylindrical body. Japanese Patent Laid-Open No. 6-185843 cuts hard ice pillars little by little with a solid cutting cutter attached to a driven chain to produce ice pieces for shaved ice.

  Using these devices to make a large amount of sticky large snow ice mass into a snowy state is too low in efficiency, and the equipment scale becomes very large and expensive.

  Moreover, in the conventional equipment which puts an ice block from the upper part of the equipment, the large snow ice block must be lifted high by a forklift, and there is a risk of causing an occupational accident.

JP-A-8-54166 JP-A-6-331247 Japanese Utility Model Laid-Open No. 01-041062 JP-A-6-185843

  The purpose of this application is to provide an inexpensive and safe apparatus for efficiently returning a large snow ice block in which snow-like sea ice is hardened in a transport container.

  The gist of the present application is a snow and ice lump placing table that can be moved, a chain that has a tool for scraping the snow and ice lump, and a snow and ice lump removal device that has a fixed blade and a rotary blade that crush the scraped snow and ice pieces. The scraping tool has a chevron shape with a top in the center of the width, and is provided with irregularities on the inclined part extending from the top to both ends to form a scraping part. This is a snow and ice lump device that is bent at both ends and fixed to a chain at both ends.

  In addition, it comes with a snow and ice lump carry-in stand in which a horizontal plate with wheels and a vertical plate are joined in an L shape, and the upper side of the vertical plate and the upper side of the carry-in door provided in the ice removing device can be rotated 180 degrees or more. This is a snow and ice lump removing device that is connected to the outer shell of the ice removing device and has a structure in which the lower side of the carry-in door can be rotated 90 degrees or more to the outside of the device.

  The scraping tool is scraped by an uneven tool slope while pulling both ends of the tool with a chain, with the width of the scraping tool oriented at a right angle to the direction of travel and the center top side against the surface of the snow ice block. The scraped ice pieces are transported downstream while being moved to the inside of the “ku” -shaped tool, and crushed into snow-like ice by a fixed blade and a rotating blade.

  The reason why the scraping tool is in the shape of a mountain is to prevent the tool from escaping by creating a catch at the top of the slippery surface of snow and ice. The concavo-convex portion is provided to allow a part of the snow and ice pieces to escape and reduce the scraping resistance. Furthermore, since the tool is connected to a chain that easily stretches, if excessive cutting resistance is applied, the tool escapes in a direction that reduces the resistance, and the remaining part is scraped off by the subsequent blade.

  The carry-in door and the carry-in stand are used for guiding the large snow ice block to the stand in the apparatus only by the forklift driver who transported the snow ice block. By placing the snow and ice litter container on the horizontal plate of the L-shaped loading table by forklift and rotating the loading door 90 degrees outward about its lower side, the loading table also falls 90 degrees toward the device in conjunction with the container. Move to a horizontal vertical plate. At this time, the snow / ice block in the container also slides onto the carry-in door that has fallen horizontally.

  Subsequently, by rotating the carry-in door 90 degrees to the equipment side in the opposite direction, the vertical plate of the carry-in base and the joint of the carry-in door compete upward, and the solid sea ice on the carry-in door is placed on the stand in the device. Be pushed to.

  Wheels are provided on the ground plane side of the horizontal plate and the vertical plate to smoothly move the loading table.

  The present application does not destroy large snow ice blocks with strong force, but returns them to snowy ice with a simple device by combining scraping of the surface of large snow ice blocks and crushing of scraped small ice pieces. Is possible.

  In addition, by attaching a loading table to the loading door that can rotate around the upper and lower sides, a large amount of snow and ice can be installed in the ice removing device with almost no effort. To increase.

  Hereinafter, embodiments of the present application will be described with reference to FIGS.

  In the figure, reference numeral 1 denotes a snow ice lump scraper, 2 a scraped snow ice piece crusher, 3 a solid sea ice L-shaped loading table, and 4 a crushed snow ice storage container. In FIG. 3, the snow and ice lump placing table 5 below the scraper 1 can be moved up and down by a hydraulic cylinder 6. The chain 7 constituting the scraper 1 is provided with a scraping tool 9 for the snow and ice lump 8, which is rotated by a pulley 10 in the direction of the arrow.

  As shown in FIG. 4, the scraping tool 9 has a mountain shape having a top at the center of the lateral width, connects both ends 11 to a chain, and scrapes the snow and ice lump 8 with an inclined portion 12 provided with irregularities. The uneven portion 12 of the inclined portion is for reducing the scraping resistance and forcibly scraping the hardened ice surface, and it is desirable that the tip has an acute angle as shown in FIG. . Further, as shown in FIG. 2, the scraping tool 9 is bent in a “<” shape with respect to the traveling direction at the center of the lateral width at the top.

  A slide 13 is arranged downstream of the chain 7 and a stationary blade 14 and a crushing gap 15 are arranged at the end of the slide 13, and the crushing gap 15 can be adjusted by shifting the position of the crotch gap 15. The rotary blade 16 is a rotary cylinder provided with a plurality of blades at equal intervals. Below the crushing gap 15, a container 4 for storing snowy seawater ice is placed.

  As shown in FIG. 4, the L-shaped carry-in table 3 is a combination of a horizontal plate 17 and a vertical plate 18 in an L shape, and wheels 19 and 20 are attached to outer surfaces to be grounded, respectively. The vertical plate 18 is joined to the upper side 22 of the carry-in door 21 so as to be able to rotate at an angle of 180 degrees or more. The carry-in door 21 is further joined to the outer shell of the ice removing apparatus by a mechanism that can be rotated 90 degrees or more toward the carry-in side at the lower side 23 portion.

  Next, the operation of the above apparatus will be described.

  The snow and ice lump 8 placed on the table 5 of the scraper 1 is lifted upward by the hydraulic cylinder 6 and scraped off from the surface by a scraping tool 9 protruding from the rotating chain 7. The scraps of snow and ice that have been scraped are pushed on the snow and ice lump while being collected inward by the bent scraping tool 9 having a "<" shape, and slide on the slide 13 to reach the vicinity of the crushing gap 15. . It is crushed by the fixed blade 14 and the rotary blade 16 disposed on the left and right sides of the gap 15, becomes snow-like ice, falls from the gap 15, and is accommodated in the lower container 4.

  The rising speed of the pedestal 6 is set according to the hardness of the solid sea ice or the particle size of the scraped ice. Further, the interval of the crushing gap 15 is also adjusted by shifting the position of the rotary blade according to the particle size and viscosity of the crushed snow-like ice.

  FIG. 5 shows a procedure for placing solid sea ice on the stage 6. The container containing the snow ice block 8 carried from the remote ice making factory is unloaded by a forklift or the like and lowered onto the horizontal table 17 of the L-shaped carry-in table 3. Next, the sprocket 26 meshed with the chain installed on the arc 25 of the quarter-circular side plate 24 attached to the carry-in door 21 is rotated, and the carry-in door 21 is rotated to the outside of the apparatus to be connected thereto. The carry-in table 3 is also pushed out and rotates as in (2) and (3). When the vertical plate 18 rotates more than the horizontal as in (4), the snow and ice lump 8 slides out from the container 27 that has been laid down. Therefore, the sprocket 26 is reversely rotated to return the carry-in door 21 and the carry-in table 3 together with the quarter-circular side plate 24 to the initial position. The empty container 27 is placed on the initially placed horizontal plate.
