TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a buffer mechanism of a storage device that buffers an impact when a lump is put into the storage device and prevents crush of the lump.
[0002]
[Prior art]
In general, a storage device such as a hopper is used for storing the lump. As shown in FIG. 4, the conventional lump hopper 31 is provided with a charging chute 33 at an upper portion of a storage space S surrounded by a vertically long casing 32 and a cutout device 34 at a lower portion. The lump B input from 33 falls in the storage space S and is stored. When there is no or a small amount of the stored bulk material B in the storage space S, the falling distance is long, and therefore, the input bulk material B increases the falling speed, and is reduced by the casing 32 and the stored bulk material B. The impact at the time of the collision becomes excessive and is crushed.
[0003]
Therefore, in the storage space S, a buffer mechanism called a lock ladder frame 35 is provided in connection with the charging chute 33 in order to buffer an impact when the bulk material B is charged.
The lock ladder frame 35 is a structure having a rectangular cross section and a vertically long structure, and as shown in FIGS. 5 and 6, a main frame formed by connecting a beam 46 and a beam 47 in multiple stages to form a frame. Inside each step of the main frame 36, baffle plates 37 that shield substantially half of the cross section of the main frame 36 are alternately arranged left and right so as to be staggered when viewed from the front. The two left and right side surfaces which are the back side of 37 are covered with side plates 39.
[0004]
On the upper surface of the baffle plate 37, a partition plate 38 having a trapezoidal shape as viewed from the front and having a base length equal to the length of the baffle plate 37 is set such that the oblique side faces inward (open side of the baffle plate 37). Is provided. Two partition plates 38 are fixed on one baffle plate 37 at a predetermined interval, thereby forming a self-dead chamber 42. Further, since the bottom side of the partition plate 38 is fixed to the baffle plate 37 and the side thereof is fixed to the side plate 39 of the main frame 36, the partition plate 38 serves as a reinforcing material for the baffle plate 37.
[0005]
The upper end surface of the lock ladder frame 35 is covered with a top plate 40, and a passage port 41 is opened in the top plate 40 at a position offset from the center so as to face the baffle plate 37 immediately below. The lower end of the input chute 33 of the hopper 31 is inserted through the passage opening 41.
When the block B is put into the hopper 31, the block B enters the lock ladder frame 35 from the input chute 33, is captured by the uppermost baffle plate 37, and is accumulated in the self-dead chamber 42 in the partition plate 38. . When the self-dead chamber 42 is filled with the lump B, the filled lump B forms an inclined surface having substantially the same slope as the hypotenuse of the partition plate 38 when viewed from the front.
[0006]
When the lump B is subsequently supplied, the lump B collides with the inclined surface of the lump B formed on the uppermost baffle 37 to reduce the momentum of the loading, and the lump B on the second baffle 37 Falls and is caught. When the mass B is further supplied, the inclined surface is formed by the mass B filled also on the second-stage baffle plate 37, and thereafter, the inclination of the mass B is similarly repeated in the lower-stage baffle plate 37. A surface is formed.
[0007]
When the inclined surfaces of the block B are formed on all the baffles 37, the passage space of the block B in the lock ladder frame 35 has a zigzag shape. Therefore, the lump B fed thereafter is repeatedly collided with the lump B forming the inclined surface, and is stored below the hopper while reducing the momentum of fall.
(See, for example, Patent Document 1).

[Problems to be solved by the invention]
However, if the low-strength lump B is thrown into the lock ladder frame 35, the lump L may drop when the lump B falls on the baffle plate 37 or when the lump L that collides with the lump B forming the inclined surface may collide. There was a problem that it was crushed by an impact.
The present invention solves such a problem in the buffer mechanism of the storage device, and an object of the present invention is to provide a buffer mechanism of the storage device that can prevent crushing even when a low-intensity lump is charged. .
[0010]
[Means for Solving the Problems]
The present invention relates to a storage chute having an input chute at an upper part, a lock ladder frame connected below the input chute, and a cutout device at a lower part, wherein an upper end of a rubber plate is fixed to a beam of the lock ladder frame, The lower end of the rubber plate extends below the baffle plate of the lock ladder frame to form a zigzag inclined surface of the rubber plate covering the self-dead chamber, and the lower end of the rubber plate is inclined one step below the inclined surface of the rubber plate. The above-mentioned subject is solved by making it contact.
[0011]
When a lump is put into the storage device, the lump enters the lock ladder frame from the charging chute, collides with the inclined surface of the rubber plate, and the momentum of the fall is reduced. The lump whose falling momentum is reduced then falls on the inclined surface of the lower rubber plate. Since the lower end of the upper rubber plate and the inclined surface of the lower rubber plate are in contact with each other to close the passage where the lump falls, the fall of the lump momentarily stagnates at this contact point. Since the weight exceeds the elastic force of the rubber plate, the lump pushes open the contact portions of the upper and lower rubber plates in the closed state, and further falls.
[0012]
In this way, the lump of the mass is reduced on the sloped surface of the rubber plate and falls while sequentially pushing and opening the contact points of the upper and lower rubber plates, so that the drop momentum increases to the bottom bottom of the hopper. , It can be stored without crushing.
When a slit is formed at the lower end of the rubber plate at a position that comes into contact with the inclined surface of the lower rubber plate, the resistance when the lump passes through the contact point of the upper and lower rubber plates can be reduced, and the lump can be reduced. Abrasion of objects can be prevented.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a front view of a buffer mechanism of a storage device according to an embodiment of the present invention, FIG. 2 is a partial front view showing a configuration of a lock ladder frame, and FIG. 3 is a partial side view showing a configuration of a lock ladder frame. .
The basic configuration of the buffer mechanism of the storage device of the present invention is common to the buffer mechanism of the conventional storage device.
[0014]
The hopper 1 serving as a storage device for the lump B is provided with a charging chute 3 at an upper portion of a storage space S surrounded by a vertically elongated casing 2 and a cutout device 4 at a lower portion. A lock ladder frame 5 is provided so as to be connected.
The lock ladder frame 5 is a structure having a rectangular cross section that is long vertically and has a square shape. The main frame 6 is formed by connecting the beams 18 and the beams 13 in multiple stages to form a frame shape. The baffle plates 7 that shield substantially half of the cross section of the main frame 6 are alternately arranged on the left and right sides so as to be staggered when viewed from the front. Of the four side surfaces of the main frame 6, two side surfaces that are the back side of the baffle plate 7 are side plates 9. (Some gaps may be provided above the partition plate 8).
[0015]
On the upper surface of the baffle plate 7, a partition plate 8 having a trapezoidal shape when viewed from the front and having a base length equal to the length of the baffle plate 7 is set such that the oblique side faces inward (open side of the baffle plate 7). Is provided. Two partition plates 8 are fixed per one baffle plate 7, thereby forming a self-dead chamber 12. Further, since the bottom side of the partition plate 8 is fixed to the baffle plate 7 and the side side is fixed to the side plate 9 of the main frame 6, the partition plate 8 serves as a reinforcing material for the baffle plate 7.
[0016]
The upper ends 14a of the rubber plates 14 are fixed to the beams 13 of each step of the main frame 6, respectively. The rubber plate 14 has a zigzag inclined surface 14c covering the self-dead chamber 12 in the lock ladder frame 5, and the lower end portion 14b of the rubber plate 14 extends until it contacts the inclined surface 14c one step below. The self-dead chamber 12 may be filled with a lump B or the like. A slit 15 is provided at a position of the lower end portion 14b of the rubber plate 14 that comes into contact with the lower inclined surface 14c.
[0017]
The upper end surface of the lock ladder frame 5 is covered with a top plate 10, and a passage port 11 is opened in the top plate 10 at a position offset from the center so as to face the baffle plate 7 immediately below. The lower end of the input chute 3 of the hopper 1 is inserted through the passage opening 11. Further, a rubber plate 16 is hung downward from the passage opening 11 so as to face an inclined surface 14 c formed by the rubber plate 14.
[0018]
When the lump B is put into the hopper 1, the lump B enters the lock ladder frame 5 from the loading chute 3, is guided by the rubber plate 16, collides with the inclined surface 14c of the rubber plate 14, and the momentum of the fall is reduced. Can be The lump B, whose falling momentum has been reduced, slides on the inclined surface 14c and falls to a contact point between the lower end portion 14b of the rubber plate 14 and the inclined surface 14c of the rubber plate 14 one step below.
[0019]
At the contact points of the upper and lower rubber plates 14, the passage space of the block B is closed, so that the movement of the block B momentarily stagnates, but the block B is moved to the lower end of the upper rubber plate 14. 14b is pushed up to open the contact portion and slide down on the inclined surface 14c of the lower rubber plate 14.
In this way, the lump B falls on the inclined surface 14c of the rubber plate 14 and drops while pushing and opening the contact points of the upper and lower rubber plates 14 sequentially, so that the lump B reaches the lowermost bottom of the hopper 1. Since the momentum does not increase, the lump B having low strength is stored without being crushed.
[0020]
Since a slit 15 is provided at a position of the lower end portion 14b of the rubber plate 14 which is in contact with the inclined surface 14c of the lower rubber plate 14, the lump B passes through the contact position of the upper and lower rubber plates 14. The frictional resistance at the time of cutting is appropriately reduced, and the agglomerate B can be prevented from being worn. This frictional resistance can be appropriately adjusted by changing the setting of the interval between the slits 15. For example, it is possible to adjust the cushioning action such that the interval between the slits 15 is made wider for the rubber plate 14 above the lock ladder frame 5 and becomes narrower as it descends.
[0021]
In addition, in the buffer mechanism of the storage device, since the falling path of the lump B is covered with the rubber plate 14 as a buffer, vibration and noise when the lump B is thrown can be reduced.
[0022]
【The invention's effect】
As described above, the buffering mechanism of the storage device of the present invention can prevent crushing even when a low-strength lump is charged, and can reduce noise when the lump is charged.
