Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for disintegrating aggregated and consolidated lumps, and more particularly, for disintegrating aggregates that are accumulated and tend to consolidate with each other, such as crushed ice blocks. This invention relates to a device for easily disintegrating and separating the lumps in a stocker that stores them when the lumps become solidified and cannot be carried out from the storage, making it easier to carry out the lumps.

BACKGROUND ART For example, on fishing boats and fishing ports, it is common to cover the catch with a large amount of crushed ice blocks and preserve them frozen, and for this reason, there is a strong demand for crushed ice blocks. The crushed ice blocks are generally obtained by crushing plate ice produced by a large ice maker using an ice crusher to form a large amount of small ice blocks, and are piled up and stored in an ice storage box, and are placed at the bottom of the box. It is designed to be carried out of the warehouse as needed by means such as a screwdriver.

Problems to be Solved by the Invention By the way, as a physical property of ice, which is a fusible solid, this crushed ice block has a phenomenon (caking) in which crystal particles agglomerate into large clumps. Often makes removal of crushed ice blocks difficult. Considering the fact that the freezing effect of ice cubes is greater at temperatures close to the melting point as long as it is below the melting point, if crushed ice cubes are to be stored for a relatively long period of time, the inside of the ice storage should be forcedly cooled. The internal temperature is maintained at around -10℃. However, even if the crushed ice blocks put into the ice storage are sufficiently drained in a solid-liquid coexistence phase at 0°C, they will inevitably have some moisture attached to them.
This moisture is frozen by the cold air in the ice storage, causing condensation between particles, leading to the solidification (blocking) of ice blocks. Moreover, when a large amount of crushed ice blocks are deposited, the solidification is promoted by the accumulated pressure.

Furthermore, when a large amount of ice blocks accumulates, there is a tendency for them to form bridges (arching) inside the ice storage tank due to the characteristics of powder and granules, and therefore, while the ice blocks are being carried out from the bottom of the ice storage tank using a screw, they arch internally and form a cavity. This makes it extremely difficult to subsequently remove the crushed ice blocks from the warehouse.

In this way, ice blocks solidify (blocking) or bridge (arching) inside the ice storage.
As an example of a means to deal with the inconvenient phenomenon in which the ice mass becomes difficult to collapse due to its own weight, Figure 14a
The structure shown in is proposed. This ice storage 12 is provided with an unloading screw 10 near the bottom, and a plurality of rotatable crushers 14 each having a protruding pin are arranged in a plurality of stages. However, even if the crusher 14 is forcibly rotated synchronously when the ice block group is carried out, only the ice block group around the crusher collapses, as shown in FIG. 14b, and bridging phenomena etc. occur in other parts. The reality is that the disadvantage of remaining ice blocks and making it difficult to remove them remains unresolved.

Further, as shown in FIG. 1 of Japanese Utility Model Publication No. 38-4008, a diaphragm 7 is provided along the inner wall of the hopper 1,
A means for preventing the arching of small ice blocks that tend to occur near the exit of the hopper by vibrating the ice has also been proposed. However, in a large-capacity ice storage where a large amount of ice is stored, the total weight of the crushed ice that accumulates inside the storage becomes 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.

Furthermore, the "crushed ice supply device for freezing" described in Japanese Patent Application Laid-Open No. 59-60471 has vertical vibration plates 15, 15 whose left and right bottom parts are constructed as separate bodies, respectively, and pivot points 16, 16 on the inside thereof. A structure is disclosed in which the diaphragms 15, 15 are pivotally connected to each other, and the diaphragms 15, 15 are vertically oscillated by vertical vibration mechanisms 17, 17 provided individually. In the configuration described in this publication, the total weight of the stored crushed ice blocks is distributed on the upper surfaces of the upper and lower diaphragms 15, 15, and in this state, both diaphragms 15, 15 are oscillated in the vertical direction. It is intended to
However, the device described in the publication and the invention of the present application,
As mentioned earlier, this relates to a stockker that stores large amounts of crushed ice used to preserve catches at fishing ports, for example, and has a storage capacity of 5 tons of ice blocks for small ones and 20 tons for large ones. ing.

Therefore, if this capacity were to be completely filled with crushed ice blocks, the total weight would be extremely large. However, in the device described in this publication, as mentioned above, the total weight of the crushed ice cubes is distributed flatly on the upper surfaces of the upper and lower vibration plates 15, 15, so in order to swing the crushed ice cubes in the vertical direction, it is necessary to A huge driving force is required to move the entire weight of the mass upwards. Therefore, apart from small-scale ones, it is almost impossible to create diaphragms 15, 15 on which a large mass weighing 5 to 20 tons is mounted with the configuration described in this publication. Further, excessive force is concentrated on the pivot points 16, 16, and the mechanical structure must be extremely rigid.

Purpose of the Invention The present invention has been developed 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 transport them. This was proposed in order to solve this problem in an appropriate manner, and by using simple means to reliably collapse and separate the accumulated and mutually solidified lumps, it prevents 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 overcome the above problems and achieve the intended purpose, the device for collapsing accumulated and solidified lumps according to the present invention includes a storage chamber having a closed structure using a heat insulating material; In a lump stocker comprising a housing-shaped storage tank disposed inside the storage tank for accumulating and storing lumps and transporting the lumps from the lower part as required, the housing-shaped storage tank is , vertical side walls facing each other in the longitudinal direction, vertical side walls facing each other in the transverse direction that intersect with the vertical side walls, and an integrated structure that is separated from these vertical side walls and slopes in an inverted chevron shape from the upper end in the longitudinal direction toward the center. and a boat-shaped bottom with a flat surface, and a shaft extending horizontally in the longitudinal direction is disposed at the bottom of the storage, and the shaft swings the center of the lower part extending in the longitudinal direction of the boat-shaped bottom. The shaft is movably supported to support the entire load of the hull bottom, and an appropriate drive means is connected to the outer surface of the hull bottom, and the lateral pressing force and The present invention is characterized in that the boat-shaped bottom section is configured to swing laterally by a predetermined angle with respect to the vertical side wall by applying a tensile force to the outer surface of the bottom section.

Embodiments Next, a preferred embodiment of the apparatus for disintegrating accumulated solidified lumps according to the present invention will be described below with reference to the accompanying drawings. 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 an explanation will be given regarding an ice storage warehouse that accumulates and stores large amounts of them. However, the present invention is not limited to this. It's not something you can do. Therefore, in addition to crushed ice blocks,
It can be successfully applied to all kinds of lumpy materials such as wood, chips, coke, etc., which cause the blocking or arching phenomenon due to accumulation. In addition, in this specification, "consolidation" refers to "blocking" in which lumps are firmly bonded to each other due to interparticle coagulation or entanglement.
The term is used to include both "arching" and "arching", which is crosslinking within a storage room.

FIG. 10 is a partially cutaway side view showing the overall structure of an ice storage unit incorporating the disintegration device according to the present invention, FIG. 1 is a cross-sectional view taken along the line -- in FIG. 10, and FIG. FIG. 2 is a perspective view showing a schematic configuration. In the figure, reference numeral 16 indicates an ice storage made of, for example, a prefabricated warehouse, and this ice storage 16 has a double sealed structure in which a heat insulating material is provided inside the structural material such as the wall surface to improve heat insulation. The inside of this ice storage 16 is
Convection cooling is forcibly performed by a refrigeration unit (not shown). An ice storage (stocker) 18 in which the device according to the present invention is implemented is housed in the ice storage 16, and crushed ice blocks 20 are discharged and supplied into the ice storage tank 18 and accumulated and stored up to a predetermined level. In this specification, the casing-like container in which the crushed ice blocks 20 are directly deposited and stored is referred to as the "ice storage tank 18", and the casing that defines the cooling space that seals and stores the ice storage tank 18 is referred to as the "ice storage 16". As such, there is a distinction between the two.

As shown in FIG. 10, at the top of the ice storage 16,
Ice making unit 22 that generates multiple sheets of ice at the same time
is installed, and the ice sheets produced here are crushed into a large amount of small ice blocks by the crushing mechanism shown in FIG. It's summery.

As shown in FIGS. 1 and 2, for example, the ice storage tank 18 has a side wall portion 26 forming four peripheral side surfaces of its housing, and a bottom surface separated from the side wall portion 26 as a separate body. A boat-shaped bottom 28 is defined. That is, the side wall portion 26 has a pair of vertical side walls 26 extending in the longitudinal direction and facing each other.
a, 26a, and a pair of vertical side walls 26b, 26b extending in the transverse direction perpendicular thereto 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 pillars 30 that are vertically arranged at predetermined positions in the ice storage 16, and occupies approximately the entire volume of the inside of the ice storage container 16. is fully open. Further, below the side wall portion 26, a boat-shaped bottom portion 28 provided separately from the side wall portion 26 has inclined planes 28a and 28b which are respectively inclined at a predetermined angle from both ends in the longitudinal direction toward the center portion, as is clear from the drawing. It is composed of , and has an inverted chevron shape as a whole.
The vertical dimension of the short side wall 26b is set to be larger than the vertical dimension of the long side wall 26a by the height of the boat-shaped bottom 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. In addition, the boat-shaped bottom 28
The central part in the longitudinal direction is formed as a flat part as shown in the figure, and a screw 34 for transporting lumps is horizontally and rotatably disposed slightly above this flat bottom part. extending in the direction. This screw 34 is driven by a motor 36 with a speed reducer as shown in FIG.
It is now being transported towards.

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. Also, a pair of bearings 40, 40 are installed at required positions on the bottom of the ice storage 16.
A support shaft 42 is inserted into the bearing 40.
By inserting the support plates 39 through the respective support shafts 42, the boat-shaped bottom portion 28 is configured to be able to swing left and right at a desired angle about the support shaft 42.
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 ice storage 16, but in the embodiments shown in FIGS. 2 to 7, the minimum unit is An example is shown in which only one unit is provided.

In this way, both walls 26 of the housing in the ice storage tank 18
A boat-shaped bottom portion 28, which is pivotally supported to be swingable from side to side below, 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 FIG. 2, power is transmitted from a dedicated motor 44 via a sprocket 46 and a chain 48 to a rotating shaft 52 supported on a bearing 50, and from this rotating shaft 52 further via a sprocket 54 and a chain 56. Power is transmitted to a common shaft 60 inserted through a pair of bearings 58 vertically arranged at predetermined positions in the ice storage 16. Eccentric arms 6 are provided at both ends of the common shaft 60, respectively.
2 is fixed, and a crank arm 64 is rotatably supported at the end of this arm 62 via a shaft pin 66.

Further, a pair of bearings 68, 68 are mounted on the back side of one inclined bottom surface 28b of the boat-shaped bottom portion 28, spaced apart by a predetermined distance.
is fixed, and a support shaft 70 is fixed to this bearing 68.
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. If the motor 44 is rotated by appropriately selecting the relative ratio of the lengths of the eccentric arm 62 and the crank arm 64,
An eccentric arm 62 and a crank arm 64 provided on the common shaft 60 perform the required cranking motion, which causes the boat bottom 28 to swing about the shaft 42 within a required angular range. In the illustrated example, a crank rocking mechanism is used as the drive mechanism, but instead of this, an actuator such as a hydraulic cylinder and a mechanism for converting to rocking motion may be combined as appropriate.

As is clear from the explanation of the operation shown in FIGS. 7a to 7c, the boat-shaped bottom 28 swings left and right at a required central angle with respect to the lower edges of the longitudinally opposing side walls 26a, 26a of the side wall 26. . Therefore, the lower edges of the side walls 26a, 26a and the boat-shaped bottom 28
The upper edges of both inclined planes 28a and 28b constituting the slanted surfaces 28a and 28b temporarily form large gaps alternately along the longitudinal direction during the swinging thereof. Therefore, if this is left as it is, the small ice cubes in the ice storage tank 18 will fly out through the gap, or the small ice cubes will get caught between the upper and lower edges, causing the boat-shaped bottom 28 This will impede the smooth rocking of the

Therefore, as shown in FIGS. 1, 2, and 7, the lower end edges of the longitudinally opposing side walls 26a, 26a are each bent outward by a predetermined dimension to form a so-called skirt 26c. It has been done.
Further, the upper edges of both inclined planes 28a and 28b of the boat-shaped bottom 28 are also bent outward by a predetermined distance to form a skirt 28c. and the seventh
As shown in FIG.
The ridge portion a is located slightly inward from the open end of the inclined skirt 26c. Also, the left inclined plane 2
The ridge portion 8b is set in a positional relationship such that it is substantially aligned with the ridge portion which is the folding line of the inclined skirt 26c. Therefore, even if the boat-shaped bottom 28 swings, no space is formed between the longitudinally opposing side walls 26a, 26a, and the crushed ice blocks 20 are prevented from falling from the ice storage tank 18. Ru. Note that most of the weight of the large amount of crushed ice blocks 20 accumulated in the ice storage tank 18 is applied to the boat-shaped bottom part 28, and the strong lateral pressure of the ice blocks is applied to the side wall part 26. Needless to say, the mechanical structure must be designed to withstand the load.

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 ice storage tank 18 and extends in the longitudinal direction. In cooperation with the member 72, the solidified ice mass can be compressed and forcibly collapsed. As shown in FIG. 1, it is most effective for this rod member 72 to be positioned on or in the vicinity of an arc extending the rocking locus of the boat-shaped bottom 28 when it swings about the shaft 42. .

Further, the rod member 72, as shown in FIG.
Sprockets 76, 7 are provided at each end of the rotating shaft 52 and the rod member 72 of the crank rocking mechanism, with pins 74 inserted and supported alternately along the longitudinal direction thereof.
It is 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 chain 77 and the boat-shaped bottom 28.

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, the double inclined plane 2 of the hull bottom 28
In the area spanning between 8a and 28b and located slightly above the unloading screw 34, no matter how the boat-shaped bottom 28 shakes, the ice blocks only move integrally with the bottom and are not effectively collapsed. There is. Therefore, in order to prevent this, Figures 2 to 7
A flap 78 as shown is disposed 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 this opening 80. The upper end portion is connected via a hinge 82 so as to be openable and closable. This flap 78 also
For example, the hinge 82 is made of a stainless steel plate.
As can be seen particularly from FIGS. 1 and 5, skirts 84 are formed at right angles on the three unattached end edges, that is, the left and right edges and the lower edge. When the flap 78 swings about the hinge 82 as the boat-shaped bottom 28 swings, a gap is formed between each end edge of the skirt 84 and the opening 80. This is to prevent the crushed ice blocks 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 ice storage 1
A support rod 88 of the required height arranged perpendicularly to the bottom surface of 6
The protrusion 86 rests on the top of the flap 7.
8 is now supported. The relative positional relationship between the surface of the flap 78 and the inclined plane of the boat-shaped bottom 28 that supports it via the hinge 82 is such that, for example, when the flap 78 is provided on the right inclined plane 28a in FIG. arm 64
When the bottom dead center is reached and the boat-shaped bottom 28 is tilted to the left as much as possible, as shown in FIG. 7c, the flap surface and the inclined plane 28a become flat. Further, when the crank arm 64 reaches the top dead center as shown in FIG.
The flap 78 supported by the flap 78 also projects upwardly to the greatest extent with respect to the inclined plane 28a, but the skirt 84 has not yet come away from the opening 80. In addition, in the neutral position of FIG. 7b, the flap 78
is adapted to protrude by about half the height with respect 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 an example in which the flap 78 is provided on the flap 78 has been described, in reality, as shown in FIGS.
It is recommended to provide a flap 78 at b. This is because, as shown in FIG. 6, by widening the flap 78 to fully expose the opening 80, maintenance and inspection of the crank rocking 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 series in the longitudinal direction within the ice storage 16, and preferably three boat-shaped bottom sections 28 having the same configuration are provided. However, each adjacent boat-shaped bottom 28 is
They are driven to swing relative to each other by a crank swing mechanism with a phase difference of, for example, 180°. Each hull bottom 2
As shown in the figure, power is transmitted to the crank mechanism for driving the crankshafts 8 through a sprocket 54 and a chain 56 provided on a common rotating shaft 52, and the phase difference can be easily set by the manner in which each chain 56 is engaged. FIG. 9 shows a state in which a plurality of boat-shaped bottom sections 28 are disposed in the longitudinal direction in this manner and are oscillated with a required phase difference between them. With this configuration, the ice blocks accumulated and solidified on each boat-shaped bottom 28 are cut off between adjacent ends of the boat-shaped bottom 28 by the rocking performed with the phase difference. can be effectively destroyed.

Regarding the ancillary structure of the ice storage 16 in which the disintegration device according to the present invention is implemented, FIG. 12 shows a chute 24 that communicates the ice making unit 22 with the ice storage tank 18 in the storage 16. 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 crushing mechanism consisting of a rotary blade 94 installed in the ice making unit 2 is provided.
The plate ice produced in step 2 is passed through a crushing mechanism and crushed to obtain the aforementioned crushed ice blocks 20.
An oblique punching metal 96 is disposed below the rotary blade 94 to collect water droplets coming from the ice making unit into a drain 98. Therefore, the risk of the water droplets falling into the ice storage tank 18, adhering to the crushed ice blocks 20 deposited in the tank, and then freezing, thereby promoting the solidification of these crushed ice blocks, is avoided.

Further, below the crushing mechanism of the chute 24, a lid body 1 is provided.
00 is tiltably suspended and supported, and the passage of the chute 24 is normally closed to prevent the cold air in the ice storage 16 whose interior is kept cool from escaping to the ice making 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 can be seen from FIG. 12 and FIG. 1, a diffuser plate 102 having an inclined chevron cross section is disposed horizontally just below the opening of the chute 24 in the ice storage 16, and the ice is emitted from the chute 24. The crushed ice blocks 20 are widely spread in the ice storage tank 18. Note that the reference numeral 104 indicates the motor 10
6 indicates a rotating rod that rotates horizontally to stir up ice blocks that have accumulated above a predetermined level. 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 installed in the control circuit system of the device of the present invention shown in FIG. The ice discharge port 38 is provided in front of the unloading screw 34 extending from the ice outlet 38 to the ice outlet 38 . The ice discharge port 38 is configured as an inclined chute, and a lid body 110 is suspended and pivotally supported at the open end thereof, and an ice detection plate 112 is pivotally supported in a tiltable manner in the middle of the inclined chute 38. There is.
A protrusion 114 extends outward from the ice detecting plate 112, and the ice detecting 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 _SW1 , causing the circuit to It is designed to detect the presence of ice.

Next, the operation of the device for disintegrating accumulated solidified lumps according to the present invention will be explained. In the ice storage 16 shown in FIG. 10, when the ice making operation in the ice making unit 22 is completed, the generated sheet ice is transferred to the
A large number of crushed ice blocks 20 are crushed by the crushing mechanism in 4.
Then, the lid 100 is pushed open and the ice falls, is diffused diagonally downward by the diffusion plate 102, and is deposited and stored in the ice storage tank 18. At this time, ice storage 18
The inside is kept cooled by the refrigeration unit (not shown) as described above, and the unloading screw 34 and the apparatus of the present invention are in a standby state with their driving stopped.

Next, when it is necessary to take out a predetermined amount of crushed ice blocks 20 stored in the ice storage tank 18, pressing the push switch PB shown in FIG. 13 energizes the relay X ₁ and closes the normally open contact X ₁ . After starting the motor 36 for carrying out the screw, it is self-held. 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 the normally closed contact of the ice detection switch _SW1 is closed. In other words, the switch SW ₁ detects that no ice is being transported, 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 as follows. It is composed of In other words, since another normally open contact X ₁ installed in series with the ice detection switch SW ₁ is closed in cooperation with the relay X ₁ at this time, the timer connected in series with it is closed.
TM ₂ is energized and its normally open contact TM ₂ will close after a predetermined set time delay to energize relay x ₃ . 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 detection switch SW ₁ has already been activated.
is opened to detect the presence of ice. Therefore, when the carry-out screw 34 is first rotated to take out the crushed ice block 20, no command is issued to the drive mechanism, and the boat-shaped bottom 28 is not swung.

While the rotation of the unloading screw 34 by the motor 36 continues and the crushed ice blocks 20 in the ice storage tank 18 are being continuously carried out from the ice discharge port 38, the ice detection switch _SW1 is pressed by the crushed ice blocks 20. It is opened to detect the presence of ice. However, due to the above-mentioned physical characteristics of ice, if the crushed ice blocks solidify with each other in the ice storage tank 18, once the ice blocks around the screw 34 have been scraped out, it is impossible to carry out the crushed ice blocks thereafter. becomes. 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 _SW1 .
Detects occurrence of blocking or arching.
That is, by closing the ice detection switch SW ₁ in the drive circuit system at the bottom of the hull and the normally open relay contact X ₁ installed in series therewith, the timer TM ₂ is energized and the normally open contact TM ₂ is Closes with a ~3 second delay. This energizes the relay _X3 and closes its normally open contact _X3 , energizes the motor 44 and operates the crank mechanism. It swings left and right by a predetermined angle around the support shaft 42, solidifies each other, and collapses the crushed ice blocks. This swinging time is set to several seconds by a timer. Note that if the crushed ice block 20 does not temporarily pass through the ice drain port 38 but continues to arrive, the timer TM ₂ is set in order to prevent the ice detection switch SW ₁ from chattering.
Accordingly, the motor 44 is driven only after a predetermined period of time has elapsed.

In addition, 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, the rod member 72 can be especially bridged to the surface facing the side wall of the ice storage tank 18. It is even more preferable that the ice blocks that are floating can be effectively collapsed by the cooperative action of the rod member 28 and the rocking boat-shaped bottom 28. In addition, the crushed ice blocks deposited below the rod member 72 and on both inclined planes 28a and 28b of the boat-shaped bottom 28 are as shown in FIGS. 7a to 7c.
Due to the movement of the flap 78, which oscillates relatively in synchronization with the oscillation of the boat-shaped bottom 28, this can also be effectively collapsed and separated.

Furthermore, crushed ice blocks that exist in a solidified state along the longitudinal direction of the ice storage tank 18 and have accumulated on the inclined plane of the hull bottom 28 other than the flap 78 formation area are removed from the hull bottom 28, which is connected to a plurality of ice cubes, as described above. By alternately swinging the crushed ice blocks with a required phase difference using the drive mechanism, the crushed ice blocks are vertically cut off by the vertical end faces of the adjacent boat bottoms, further promoting their collapse.

Effects of the Invention According to the device for disintegrating accumulated and solidified lumps according to the present invention, the storage tank is separated from the vertical side walls facing each other in the longitudinal direction and is separated from the side walls from the upper end in the longitudinal direction to the central part. The bottom center of the bottom of the boat is swingably supported by a shaft installed horizontally in the longitudinal direction at the bottom of the storage to carry the entire load. Can be supported by a shaft,
Furthermore, since a driving means is connected to the outside of the boat-shaped bottom for applying a lateral pressing force and a tensile force, when the driving means is energized, the boat-shaped bottom is moved laterally by the required angle with respect to the vertical side wall. It can be swayed. Therefore, it is possible to completely disintegrate the strongly consolidated crushed ice blocks, prevent the so-called blocking phenomenon and arching phenomenon, and realize good conveyance of the crushed ice blocks without interrupting the conveyance using a screw or the like. I can do it.

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 pivot, so we will discuss the problems first. This is fundamentally different from the above-mentioned proposal in which the inclined bottom surfaces are individually swung, and has the advantage that only a small driving force is required and the support mechanism can be of a simple structure.
