Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for disintegrating accumulated and consolidated agglomerates, and more particularly, for disintegrating agglomerates that tend to accumulate and consolidate together, such as crushed ice blocks. This invention relates to a device configured to easily disintegrate and separate the lumps when they become solidified and become impossible to carry out from the storage in a storage warehouse.

BACKGROUND OF THE INVENTION For example, on fishing boats and fishing ports, it is common practice to cover and freeze catch with a large number of ice-breaking rings, and for this reason there is a strong demand for ice-breaking rings. The crushed ice ring is obtained by crushing plate ice produced by a large ice maker using an ice crusher to form a large amount of small ice blocks, which are deposited and stored in a water storage chamber, and are crushed by a screw installed at the bottom of the chamber. It is designed to be carried out of the warehouse as necessary by means such as the following.

Problems to be Solved by the Invention By the way, this ice-breaking ring has a physical property of ice, which is a fusible solid, that causes crystal particles to aggregate and form large clumps (caking). This often makes removal of ice-breaking rings difficult. Considering the fact that the condensation effect of ice blocks is greater the closer the temperature is to the melting point as long as it is below the melting point, when preserving crushed ice rings for a relatively long period of time,
The inside of the water storage is forcibly cooled to maintain the internal temperature at around -10°C. However, even if crushed ice rings placed into a water storage are thoroughly drained in a solid-liquid coexistence phase at 0°C, they will inevitably have some moisture attached to them, and this moisture will be frozen by the cold air inside the storage. This causes condensation between particles, leading to ice blocks solidifying (blocking) together. Moreover, when a large amount of crushed ice rings are deposited, the solidification is promoted by the cumulative pressure.

Furthermore, the accumulation of a large amount of ice blocks tends to form bridges (arching) inside the water storage tank due to the characteristics of powder and granular materials, so while the ice blocks are being carried out from the bottom of the storage tank with a screw, they arch internally and form a cavity. This makes it extremely difficult to remove the crushed ice ring from the warehouse.

As an example of means for dealing with the inconvenient phenomenon in which blocks of ice solidify (blocking) or form bridges (arching) in a water reservoir, making it difficult for the blocks of ice to collapse under their own weight, A structure shown in Figure 14(a) has been proposed. This is a water reservoir 12 in which a discharge screw 10 is provided near the bottom, and a plurality of rotatable lashers 14 each having a projecting pin implanted therein are arranged in multiple stages. However, even if the crusher 14 is forcibly rotated synchronously when transporting the ice blocks, only the ice blocks around the crusher will collapse, as shown in FIG. The current situation is that the drawback that ice blocks remain and it is still difficult to remove the ice blocks has not been resolved1.

Also, as shown in Figure 1 of Utility Model Publication No. 38-4008,
A method has also been proposed in which a vibrating plate 7 is provided along the inner wall of the hopper 1 and vibrates to prevent the arching of small ice blocks that tends to occur near the exit of the hopper. However, in a large-capacity water storage where a large amount of ice is stored, the total weight of the crushed ice rings accumulated inside the storage is extremely large, and a huge load is concentrated on the diaphragm, so such technical measures are not possible. It is extremely difficult to employ them. In addition, as a further development of this mechanism, the bottom of the storage is tilted from both side walls to the center of the lower part to form an "inverted chevron" shape, and one of the sloped bottoms is pivoted to the side wall so that it can be opened and closed. At the same time,
It has also been proposed to suppress the inclined bottom surface and swing it around its pivot point. However, a large amount of lumps are stored in the storage, and the lumps are present between the side wall and the inclined bottom surface. Therefore, even if the inclined bottom surface is driven, it only presses the lump that is interposed between it and the side wall, and a powerful driving source and jll! lr1! Although it requires a mechanical structure, it is not effective in preventing arching and the like. Another disadvantage is that as a result of pressing the lump between the side wall and the inclined bottom surface, the lump is crushed into small particles.

Purpose of the Invention The present invention is aimed at, in view of the current situation in which a large amount of lumps that are relatively easy to solidify are stored, as described above, where the lumps are solidified or crosslinked in the storage, making it difficult to carry them out. This system was proposed to solve this problem in an appropriate manner, by using simple means to reliably disintegrate and separate the accumulated and mutually solidified lumps, thereby preventing the so-called blocking phenomenon and arching phenomenon. , the purpose is to realize good removal of lumps.

Means for Solving the Problems In order to achieve the above object, the present invention provides a casing-shaped storage tank configured to store a large amount of lumps in a piled state and carry out the lumps from the bottom of the storage tank. is defined into a side wall portion forming a side surface thereof, and a boat-shaped bottom portion separated from the side wall portion to form a separate bottom surface, and this boat-shaped bottom portion is pivotably supported with respect to the side wall portion. It is characterized in that it is connected to a suitable driving means, and the boat-shaped bottom is rocked by energizing the driving means.

Embodiment Next, a preferred embodiment of the apparatus for disintegrating accumulated solidified lumps according to the present invention will be described in detail with reference to the accompanying drawings. In addition, in the present invention, crushed ice blocks are exemplified as a typical example of lumps that tend to solidify with each other when piled up, and a description will be given of a water storage tank that accumulates and stores large amounts of them. It goes without saying that the present invention is not limited to the present invention, and can be effectively applied to any other lumps that cause the blocking or arching phenomenon when deposited, such as wood chips and coke. Furthermore, in this specification, the term "consolidation" is used to include both "blocking" in which lumps are firmly bound to each other through interparticle coagulation and entanglement, and "arching" in which aggregates are crosslinked within the storage chamber. be.

FIG. 10 is a partially cutaway side view showing the overall structure of a water reservoir incorporating a disintegration device according to the present invention, and FIG.
6 is a cross-sectional view taken along line I, and FIG. 2 is a perspective view showing a schematic configuration of the apparatus of the present invention. In FIG. It has a double-sealed structure with a heat insulating material inside to improve heat insulation. The inside of this water storage 16 is forcibly cooled by convection by a refrigeration unit (not shown). A water storage tank (stocker) 18 in which a device according to the present invention is implemented is housed in the water storage 16, and crushed ice blocks 2° are discharged and supplied into the water storage tank 18, and accumulated and stored up to a predetermined level. In addition, in this specification, crushed ice block 2
A casing-like container in which o is directly deposited and stored is called a "water storage tank 18", and a casing defining a cooling space that seals the water storage tank 18 is called an "ice storage 16" to distinguish between the two. .

As shown in FIG. 10, an ice making unit 22 that simultaneously generates a plurality of sheets of ice is mounted on the top of the water storage 16, and the ice sheets produced here are crushed by a crushing mechanism shown in FIG. The ice cubes turn into a large amount of small ice blocks, which fall and are discharged through a chute 24 into an ice storage tank 18 in an ice storage 16.

The water tank 18 has side walls 26 forming four peripheral sides of its housing, as shown in FIGS. 1 and 2, for example.
and a boat-shaped bottom portion 28 that is separated from the side wall portion 26 to form a separate bottom surface. That is, the side wall portion 26 has a pair of vertical sides @ 26 a extending in the longitudinal direction and facing each other.

26a, and a pair of vertical side walls 26b, 26b extending in the transverse direction perpendicular to the vertical side walls 26a and facing each other. This side wall portion 26 is made of, for example, a stainless steel plate, and is fixed to a plurality of columns 30 that are vertically arranged at predetermined positions in the water storage chamber 16, and occupies approximately the entire volume of the chamber. is fully open. Further, below the side wall portion 26, a boat-shaped bottom portion 28 provided separately from the side wall portion 26 is, as is clear from the drawings,
It is composed of inclined planes 28a and 28b that are inclined at a predetermined angle from both ends in the longitudinal direction toward the center, respectively, and has an inverted chevron shape as a whole. Note that the short side wall 26
The vertical dimension b is set to be larger than the vertical dimension of the longitudinal side wall 26a by the height dimension of the boat-shaped bottom portion 28.

The boat-shaped bottom part 28 is also made of, for example, a stainless steel plate, and is stretched over a base frame 32 formed by bending an angle steel material into an inverted chevron shape. Note that the longitudinal center portion of the boat-shaped bottom 28 is 2
As shown in the figure, it is formed in a flat part, and a screw 34 for transporting the lumps is horizontally and rotatably arranged slightly above the flat bottom part, and extends in the longitudinal direction inside the water storage tank. ing. This screw 34 is a speed reducer as shown in FIG.

It is driven by an attached motor 36 to convey the crushed ice blocks 20 in the water storage tank 18 toward a discharge port 38 provided at the front of the water storage tank 16.

As shown in FIG. 2, support plates 39 are arranged and fixed at both ends in the longitudinal direction of the back surface of the base frame 32, which constitutes a part of the boat-shaped bottom 28. Further, a pair of bearings 40, 40 are arranged at required positions on the bottom surface of the water storage 16, and by inserting the support plate 39 into the support shaft 42 inserted through the bearing 40, the boat-shaped bottom 28 is connected to the support shaft 42. It is constructed so that it can be swung left and right at a desired angle around the center.

As shown in FIGS. 8 and 10, it is preferable that a plurality of these boat-shaped bottoms 28 are arranged in series in the longitudinal direction of the water storage 16, but in the embodiments shown in FIGS. 2 to 7, the minimum unit is An example in which only one unit is provided is shown.

The boat-shaped bottom part 28, which is pivotably supported to be swingable from side to side below both walls 26 of the casing in the water tank 18, is driven to swing at a predetermined timing by an appropriate drive mechanism. In the illustrated embodiment, a crank swing mechanism is used as the drive mechanism. That is, as shown in Figure 2,
From a dedicated motor 44 to a sprocket 46 and a chino 4
8, power is transmitted to a rotating shaft 52 supported by a bearing 50, and from this rotating shaft 52, further via a sprocket 54 and a chino 56, to a pair of bearings 58 vertically arranged at a predetermined position in the water storage 16. Power is transmitted to the common shaft 60 inserted therethrough. Eccentric arms 62 are fixed to both ends of the common shaft 60, and a crank arm 64 is rotatably supported at the ends of the arms 62 via a shaft pin 66. Further, a pair of bearings 6 are mounted on the back side of one of the inclined bottom surfaces 28b of the boat-shaped bottom 28 with a predetermined distance between them.
8 and 68 are identified, and the support shaft 7 is attached to this bearing 68.
0 is rotatably inserted and supported by a shaft, and the other ends of the pair of crank arms 64, 64 are inserted through this support shaft 70. By appropriately selecting the relative ratio of the lengths of the eccentric arm 62 and the crank arm 64, when the motor 44 is rotated, the eccentric arm 62 and the crank arm 64 provided on the common shaft 60 can be rotated as required. A cranking motion is performed, which causes the boat bottom 28 to pivot about the axis 42 within a required angular range. In the illustrated example, a crank rocking mechanism is used, but instead of this, an actuator such as a hydraulic cylinder and a mechanism for converting into rocking motion may be combined as appropriate.

As is clear from the explanation of the operation shown in FIGS.
It swings left and right at a required central angle with respect to the lower edges of 6a and 26a. Therefore, the side walls 26a, 26a
and the inclined plane 28 constituting the boat-shaped bottom 28.
Large gaps are temporarily formed alternately in the longitudinal direction between the upper edges of a and 28b during the swinging thereof. Therefore, if you leave this as it is, the water tank 18
The small pieces of water inside may fly out through the gap, or the small pieces of ice may get caught between the upper and lower edges, impeding the smooth rocking of the boat-shaped bottom 28. For this reason, the first
As shown in FIGS. 2 and 7, the lower edges of the opposing longitudinal side walls 26a, 26a are bent obliquely outward by a predetermined dimension to form a so-called skirt 26c. be. In addition, the inclined planes 28a, 2 of the boat-shaped bottom 28
The upper edges of 8b are also bent outward by a predetermined dimension to form a skirt 28c. And Figure 7(a)
As shown in , when the boat-shaped bottom 28 swings and tilts to the right, the ridge of the inclined plane 28a on the right side in the figure.

It is located slightly inward from the open end of the inclined skirt 26c. Further, the ridge of the left inclined plane 28b is set in a positional relationship such that it is substantially aligned with the ridge, which is the folding line of the inclined skirt 26c. Therefore, even if the boat-shaped bottom section 28 swings, no gap is formed between the opposing longitudinal side walls 26a, 26a, and the crushed ice blocks 2o are prevented from falling from the ice storage tank 18. In addition, in the boat-shaped bottom 28,
Since most of the weight of the large amount of crushed ice blocks 20 deposited in the water storage tank 18 is applied to the side wall portion 26, and the strong lateral pressure of the ice blocks is applied to the side wall portion 26, it is necessary to have a mechanical structure that can withstand these loads. Of course, the structure is designed.

This boat-shaped bottom part 28 is energized by the drive mechanism and oscillates, thereby effectively collapsing and separating a group of strongly consolidated ice blocks, as described later.As a means for further improving the efficiency, , the following various mechanisms are preferably employed. For example, as shown in FIG. 2, a rod member 72 is horizontally fixed at a predetermined position in the center of the water tank 18 and extends in the longitudinal direction. In cooperation with the member 72, the solidified ice mass can be compressed and forcibly collapsed. This rod member 72
As shown in the figure, it is most effective to position the boat-shaped bottom 28 on or near a circular arc that extends the rocking locus when the boat-shaped bottom 28 rocks around the shaft 42.

Further, as shown in FIG. 3, the rod member 72 has pins 74 inserted and supported alternately along its longitudinal direction, and is provided at each end of the rotation shaft 52 of the crank swing mechanism and the rod member 72. It is even more effective if the rod member 72 is rotated in synchronization with the rocking of the boat-shaped bottom 28 under the power transmission action by the sprockets 76, 76 and the chino 77.

By arranging the rod member 72 in the ice storage tank 18 in this manner, the collapse and separation of the solidified ice blocks in the area located within the side wall portion 26 shown in FIG. 1 is made extremely effective. However, in the area that spans both inclined planes 28a and 28b of the boat-shaped bottom 28 and is located slightly above the unloading screw 34, no matter how the boat-shaped bottom 28 swings, the ice blocks remain integral with the bottom. Sometimes it just moves and is not effectively collapsed. In order to prevent this, a flap 78 shown in FIGS. 2 to 7 is provided on the inclined plane of the boat bottom 28. That is, a rectangular opening 80 with a predetermined size is provided in the central portion of at least one inclined plane of the boat-shaped bottom 28, and a rectangular flap 78 with a slightly smaller size is provided in the opening 80. There is also a flap 78 connected at the upper end via a hinge 82 so as to be openable and closable.

For example, the hinge 82 is made of a stainless steel plate, and skirts 84 are formed at right angles on the three unattached edges of the hinge 82, that is, the left and right edges and the bottom edge, as can be seen particularly from FIGS. 1 and 5. has been done. This skirt 84
When the flap 78 swings about the hinge 82 as the boat-shaped bottom 28 swings, a gap is formed between each end edge and the opening 80, from which the crushed ice pieces are removed. This is to prevent 20 from falling off or getting caught.

Furthermore, as shown in FIGS. 1 and 7, a protrusion 86 is formed on the back surface of the flap 78, and the protrusion 86 is attached to the top of a support rod 88 of a required height disposed perpendicularly to the bottom surface of the water reservoir 16. is at rest to support the flap 78. The surface of the flap 78 and the hinge 82
For example, in the case where the flap 78 is provided on the right inclined plane 28a in FIG.
As shown in Figure (C), when the bottom dead center is reached and the boat-shaped bottom 28 is tilted to the left as much as possible, the flap surface and the inclined plane 28a become flat. In addition, the crank arm 64 is shown in FIG. 7(a).
As shown in FIG. 3, when the boat-shaped bottom 28 reaches the top dead center and tilts to the maximum to the right, the flap 78 supported by the support rod 88 protrudes upward to the maximum with respect to the inclined plane 28a, but the skirt 84 does not close to the opening. He has yet to break away from 8o. Further, in the neutral position shown in FIG. 7(b), the flap 78 protrudes by approximately half the height relative to the inclined plane 28a. In addition, in FIGS. 1 to 4, for convenience of explanation, the inclined plane 28 is shown opposite to the side where the crank rocking mechanism is provided.
Although the example in which the flap 78 is provided in the fifth
As shown in the drawings and FIG. 6, it is actually recommended to provide the flap 78 on the left inclined plane 28b where the crank swing mechanism is disposed. This is because, as shown in FIG. 6, by widening the flap 78 to fully expose the opening 8o, maintenance and inspection of the crank swing mechanism located on the back side of the inclined plane becomes easier. At this time, the flap 78 also functions as an inspection hatch.

Next, FIG. 8 shows a plurality of boat-shaped bottom sections 28 arranged in a row in the longitudinal direction inside the ice storage 16, and preferably three boat-shaped bottom sections 28 having exactly the same configuration are provided. However, the adjacent boat-shaped bottom portions 28 are driven to swing relative to each other by a crank swinging mechanism with a phase difference of, for example, 1801 degrees. The crank mechanism that drives each hull bottom 28 is powered by a sprocket 54 and a chino 56 provided on a common rotating shaft 52 as shown in the figure, and the phase difference is easily set by the way the chinos 56 are engaged. Ru.

A state in which a plurality of boat-shaped bottom portions 28 are disposed in the longitudinal direction and are oscillated with a required phase difference with respect to each other is described in the ninth example.
With this configuration shown in the figure, the ice blocks accumulated and solidified on the respective hull bottoms 28 are cut off between the adjacent ends of the hull bottoms 28 by the rocking performed with the phase difference. can be effectively destroyed.

Regarding the ancillary structure of the water storage 16 in which the disintegration device according to the present invention is implemented, FIG. 12 shows an ice making unit 22.
A chute 24 that communicates the ice storage tank 18 in the storage 16 with the
It is shown. Inside the chute 24, as shown in the figure, there is a fixed blade 90 with a large number of pins protruding horizontally from the inner wall of the chute, and a predetermined number of pins alternately adjacent to the fixed blade 90 in the axial direction of the rotating shaft 92. An ice crusher groove consisting of an implanted rotary blade 94 is provided so that the sheet ice produced by the ice making unit 22 is passed through the crushing mechanism and crushed to obtain the aforementioned crushed ice blocks 20. .

Below the rotary blade 94 is a diagonal punching metal 9.
6 is arranged to collect water droplets coming from the ice making unit into a drain 98. Therefore, the risk that the water droplets fall into the water storage tank 18, adhere to the crushed ice blocks 20 deposited in the tank, and then freeze, thereby promoting the solidification of these crushed ice blocks, is avoided.

A lid 100 is tiltably supported below the crushing mechanism of the chute 24, and the passage of the chute 24 is normally closed so that the cool air in the water storage 16, which is kept cooled inside, is used to make ice. This is to prevent them from escaping to Unit 22. Note that the lid 100 is opened by the weight of the crushed ice chunks sliding down the chute 24, allowing the crushed ice chunks to be released.

Further, as is clear from FIG. 12 and FIG. 1, a diffusion plate 102 having an inclined chevron cross section is disposed horizontally just below the opening of the chute 24 in the water storage 16, and the water is discharged from the chute 24. The crushed ice blocks 20 are widely spread in the water storage tank 18. Note that the code 104 is
A rotary rod is shown that is rotated horizontally by a motor 106 to stir up ice blocks that have accumulated to a predetermined level or higher. A level sensor 108 is provided on the ceiling of the ice storage 16 to detect when a predetermined accumulation level has been reached.

FIG. 11 shows a specific example of the arrangement of the ice detection switch interposed in the control circuit system of the apparatus of the present invention shown in FIG. The ice outlet 38 is provided in relation to the ice outlet 38 provided in front of the ejection screw 34 extending from the ice outlet 38 to the ice outlet 38 . This ice outlet 38 is configured as an oblique chute, and a lid 11 is provided at the open end of the ice outlet 38.
0 is suspended and pivotally supported, and an ice detection plate 112 is pivotally supported in a tiltable manner in the middle of the inclined chute 38.

A projection 114 extends outward from the chute from the ice detection plate 112, and the ice detection plate is normally lifted and biased upward by a tension spring 116 shown.

When the crushed ice block 20 passes through the chute, the ice detection plate 112 moves diagonally downward against the elasticity of the tension spring 116 due to its weight, and presses the lever of the ice detection switch SW, causing the ice detection plate 112 to move diagonally downward due to its weight. It is designed to detect the presence of

Next, the operation of the device for disintegrating accumulated solidified lumps according to the present invention will be explained. In the water storage 16 shown in FIG.
When the ice making operation in the ice making unit 22 is completed, the generated sheet ice is crushed by the crushing mechanism in the chute 24,
A large number of crushed ice blocks 20 fall by pushing open the lid 100, and are diffused and released diagonally downward by the diffusion plate 102.
The water is deposited and stored in the water storage tank 18. At this time, the inside of the water storage 18 is kept cooled by the refrigeration unit (not shown) as described above, and the delivery screw 34 and the device of the present invention stop driving and are in a standby state.

Next, when it is necessary to take out a predetermined amount of crushed ice blocks 20 stored in the water storage tank 18, by pressing the push switch PB shown in FIG. 13, the relay ON is energized and its normally open contact system is closed. , after starting the motor 36 for the unloading screw,
maintain self. Note that when the rotation of the screw 34 is started, the crushed ice block 20 has not yet been delivered to the ice discharge port 38, so that the "normally closed contact of the ice detection switch SW is closed. In other words, no ice is being transported." is detected by the switch S■, but at this time there is no need to start rocking the hull bottom 28, so the drive circuit system for the hull bottom is configured as follows. Another normally open contact system installed in series with the detection switch SW1 is closed in cooperation with the cut rail, so the timer in series with this is energized, and its normally open contact TM is closed. After a delay of a predetermined set time, the relay is closed and the relay is energized.However, after the delay time has elapsed, the crushed ice block is transported by the screw 34 and reaches the ice outlet 38, and the ice has already been removed. The detection switch SW is opened to detect the presence of ice. Therefore, when the unloading screw 34 is started to rotate for the first time in order to take out the crushed ice block 20, no command is issued to the drive mechanism and the hull bottom 28 is rotated. It will not be shaken.

While the rotation of the carry-out screw 34 by the motor 36 continues and the crushed ice blocks 20 in the water storage tank 18 are continuously carried out from the ice outlet 38, the ice detection switch SVi& is pressed by the crushed ice blocks 20. It is opened to detect the presence of ice. However, due to the physical characteristics of ice mentioned above, when crushed ice blocks solidify together in the water tank 18, the screw 3
After the ice blocks around 4 have been scraped out, it will no longer be possible to remove the crushed ice blocks. At this time, the crushed ice block 20 no longer passes through the ice outlet 38, so the ice detection plate 112 rises and closes the ice detection switch SW.

Detects occurrence of blocking or arching.

In other words, the timer T1% is energized by the closing of the ice detection switch SW in the drive circuit system at the bottom of the hull and the normally open relay contact installed in series therewith, and the normally open contact TM is turned on.
, closes with a delay of, for example, 2 to 3 seconds. This energizes the relay, closes its normally open contact, and motor 4
4 is energized to operate the crank mechanism, and as shown in FIG.
) to (C), the boat-shaped bottom 28 swings left and right by a required angle about the support shaft 42 to break up the mutually solidified ice blocks. This swinging time is set to several seconds by a timer. Note that if the crushed ice block 20 does not pass through the ice outlet 38 temporarily and the crushed ice block continues to arrive, the timer TM is activated after a predetermined period of time has elapsed to prevent the ice detection switch SW from chattering. Only the motor 44 is driven.

Further, as shown in FIG. 2, by positioning the rod member 72 on an arc extending the rocking locus of the boat-shaped bottom 28 in the ice storage tank 18, it is possible to bridge the side wall of the water storage tank 18 in particular. It is even more preferable that the ice blocks that are floating can be effectively collapsed by the joint action of the rod member 28 and the rocking boat-shaped bottom 28. Further, below the rod member 72,
In addition, the crushed ice blocks accumulated on both inclined planes 28a and 28b of the hull bottom 28 are shaken relatively in synchronization with the rocking of the hull bottom 28, as shown in FIGS. 7(a) to (C). Due to the movement of the flap 78, this can also be effectively collapsed and separated.

Furthermore, it exists in a solidified state over the longitudinal direction of the ice storage tank 18,
In addition, the crushed ice blocks accumulated on the inclined plane other than the flap 78 formation area of the boat-shaped bottom 28 are removed from the boat-shaped bottom 28 which is connected to a plurality of crushed ice blocks.
By alternately swinging the crushed ice blocks with a required phase difference using the above-mentioned drive mechanism, the group of crushed ice blocks is vertically cut off by the vertical end surfaces of the adjacent boat-shaped bottoms, and their collapse is further promoted.

Effects of the Invention According to the device for disintegrating accumulated solidified lumps according to the present invention,
For example, for the side wall part that constitutes a water tank.

By simply swinging the boat-shaped bottom placed below it at the required angle, the strongly consolidated crushed ice blocks can be completely broken down, and removal using a screw or the like can be carried out smoothly without interruption. Moreover, the bottom of the hull, which supports most of the weight of a large amount of crushed ice, is pivoted around a support shaft, and the structure is such that the bottom of the hull swings when the load is applied to the shaft, so we will discuss the problems first. This is fundamentally different from the above-mentioned proposal of swinging an inclined bottom surface, and its drive mechanism can be configured extremely compactly. Moreover, since there is no risk that the crushed ice blocks will be forcibly pressed and crushed into powdered ice, the commercial value of the crushed ice blocks will not be reduced. Further, since a large number of the above-mentioned boat-shaped bottoms can be arranged in series along the longitudinal direction in the water storage tank, it is possible to easily increase the capacity of the water storage tank. As mentioned above, the device of the present invention is not limited to application to water storages where large amounts of crushed ice blocks are deposited and stored, but can also be applied to other lumps such as wood chips and coke that accumulate and cause blocking and arching phenomena. It can be successfully applied to all of the above.
