Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small grain storage for storing grains such as rice and wheat.

[0002]

2. Description of the Related Art Conventionally, small grain storages have been used to store grains such as rice while controlling insects and preventing the formation of dew and mold. In this grain store,
Generally, since an input port for inputting grains is provided in the upper part of the storage, an operator has to lift the bagged grain to above the storage in order to input the grains into the storage.

[0003]

However, the weight of bagged grains is so large that it takes a lot of labor to lift such bagged grains above the storage. In addition, the device height may increase due to an increase in the storage volume while suppressing the installation area of the device, and in such a case, it may not be possible to insert the device unless a step is used. At this time, a ready-made step stool may be used, but it is complicated to store and assemble the step stool, and a storage space for the step stool is separately required, so that the space cannot be effectively used.

Therefore, it is advisable to attach a step to the storehouse in advance, but most of the places where the storehouse is installed are barns where there is no room for installation space. In many cases, there is an installation space only in the front. Therefore, the mounting position of the step is best on the front of the storage, but the front wall of the storage is provided with an outlet for taking out grain, and when attaching the step, consider the positional relationship with this outlet. There must be.

Therefore, according to the present invention, the installation can be performed easily and quickly in order to reduce the labor of the work of throwing in the grain,
Moreover, it is an object of the present invention to provide a grain storage provided with a storage step that can be compactly stored without interfering with the work of taking out grain from the outlet.

[0006]

In order to achieve the above object, the present invention provides a grain storage having an input port for inputting grain in the upper part and an outlet for taking out grain in the lower part of the front wall. Took appropriate measures. That is, in the storage bin with a storage step according to the present invention, a pair of links in which the base end portions are pivotally connected to the front wall on the left and right sides of the outlet, and the posture can be changed between a hanging posture and a rising posture, One end is pivotally connected between the tip ends of the pair of links, and the other end is foldably pivotally connected to the other end of the footrest so as to support the footrest substantially horizontally when the pair of links is in a hanging posture. A supporting leg and a holding tool for holding the footstep in a state where the footstep is substantially along the front wall above the outlet when the pair of links are in a standing posture. There is.

[0007]

When the grain is loaded into the loading port at the upper part of the storage, one end of the stepping is hung with the pair of links in a hanging posture, while the other end of the stepping is supported by the supporting leg so that the stepping is substantially horizontal, If you do the loading work on this step,
The height of the inlet is lowered by the height of the step, and the labor is reduced accordingly.

[0008] Further, during non-loading work, the pair of links is set in a standing posture, and the platform is held in a state in which the platform is substantially along the front wall by the holder above the outlet, so that the platform can be stored compactly, Further, the stepping board does not interfere with the work of taking out the grain from the take-out port.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, the grain storage 1 is formed in a box shape having an input port 3 into which the grain 2 is input,
The input port 3 is covered with a lid 13. Wheels 25 are provided at the bottom of the storage 1, and a handle 26 is provided at the upper part of the front wall 4.
Is provided and is portable. Also, grain storage 1
In the lower part of the front wall 4 of the above, an outlet 5 for taking out the grains 2 stored in the storage 1 and a door 14 for opening and closing the outlet 5 are provided.

Supporting fittings 15 are fixed to the front wall 4 on both the left and right sides of the outlet 5, and the base ends of a pair of links 8 are attached to the supporting fittings 15 via horizontal and horizontal shafts 12. The link 8 is pivotally supported, and the posture of the link 8 can be changed between a hanging posture 6 extending downward from the support fitting 15 and a rising posture 7 extending upward from the support fitting 15.

When the link 8 is in the drooping posture 6, the tip of the link 6 is located at a height at which the worker M can move up and down,
When the link 8 is in the standing posture 7, the link 7
The tip of is positioned above the outlet 5. One end of a rectangular step 9 is pivotally connected between the tip ends of the pair of links 8. A foldable support leg 10 is pivotally connected to the other end of the step 9 via a hinge 19. When the link 8 is set in the hanging posture 6, one end is hung by the link 8 and the step 9 is made substantially horizontal, and the other end can be supported by the support leg 10. At this time, the step 9 Is installed in front of the door 14. The support leg 10
It is preferable that a synthetic resin such as rubber is attached to the end surface on the ground side to prevent slippage, and a cushioning material is provided between the front end of the link 8 and the front wall 4.

Although the supporting leg 10 has a flat plate shape in this embodiment, it may have a rectangular frame shape or a columnar shape. One end of a long holder 11 is pivotally connected to both sides of the support leg 10 via a pin 20, and the other end of the holder 11 is provided on both sides of the step 9 when the step 9 is installed. It is engaged with the protrusion 16 so as to be detachable, and holds the installation state of the step stool 9. At this time, if the grounding end side of the supporting leg 10 is slightly inclined forward so that when the worker M rests on the step 9, the step 9 can be moved backward by the load thereof. Since the movement of the front wall 4 is suppressed by contacting the front wall 4, it is possible to more reliably maintain the installation state without the step 9 falling.

FIG. 3 shows an example of the engaging portion between the protrusion 16 and the holder 11. In this example, the protrusion 16 comprises a small diameter portion 16a on the base end side and a large diameter portion 16b on the tip end side. An engaging hole 18 is provided at the tip of the holder 11 so that the large diameter portion 16b of the protrusion 16 is slightly displaced from the inserted position to prevent the protrusion 16 from coming off. More specifically, the engagement hole 18 has an insertion hole 18a through which the large diameter portion 16b can be inserted, and a small diameter portion 16a extending from the insertion hole 18a in both the longitudinal direction.
And a retaining hole 18b that can be inserted only. Therefore, even if the protrusion 16 engaged with the one retaining hole 18b swings, in many cases, the protrusion 16 moves to the other retaining hole 18b without stopping at the insertion hole 18a, and the protrusion 16 is accidentally moved. It rarely comes off.

In the modified example of the engaging portion shown in FIG. 4, the engaging hole 18 comprises an insertion hole 18a and a retaining hole 18b extending from the insertion hole 18a toward the tip side.
The tip end side of b is bent so that the projection 16 locked in the retaining hole 18b is hard to come off. In this grain storage 1, normally, a step 9 is stored so that the grain 2 can be taken out from the outlet 5. In this case, as shown by the chain double-dashed line in FIGS. 1 and 2, The pair of links 8 is rotated upward to a standing posture 7, and the step 9 is placed above the links 8 and substantially along the front wall.
Further, the supporting leg 10 is folded back and overlaps with the stepped step 5, and the other end of the holder 11 is detachably engaged with an engaging protrusion 17 provided on the front wall 4 to maintain this stored state. be able to. The locking protrusion 17 may be similar to the protrusion 16 provided on the side portion of the step 9.

In this stored state, the step pedestal 9 is located above the tip of the link 8 and therefore is located above the take-out port 5, and therefore the front of the take-out port 5 is completely opened. This does not hinder the opening / closing of the door 14 and the work of taking out the grain 2 from the take-out port 5. In this embodiment, a storage container 21 is arranged in the storage 1, and the storage container 21 has an opening 21a at its upper portion. By opening the lid 13, the grain 2 can be stored from the upper portion. Has become. The opening 21a may be closed by a slide-type inner lid.

This storage container 21 has a bracket 33 fixed in the middle of the outer peripheral surface in the vertical direction, which is long in the circumferential direction, for example, the same length as each side, and the bracket 33 projects from the four side walls of the storage 1. It is received by and is suspended in the air. Therefore, there is a gap in all between the outer peripheral surface, the bottom surface and the upper portion of the storage container 21 and the inner surface of the storage 1 and the lower surface of the lid body 13 to form the cooler air circulation space 34.

The bottom of the storage container 21 is a two-step bottom consisting of a front bottom and a high rear, and a front bottom and a rear bottom. The front part of the front bottom is the lowest, and the side wall on that side has the front wall 4 on the side. An opening 22 facing the outlet 5 is formed. A shutter 23 that opens and closes the opening 22 is provided at the lower portion of the front wall of the storage container 21, and a square tube-shaped chute 24 is pivotally supported by a hinge or the like at the front end of the front bottom. Specifically, for example, a rectangular cylindrical guide is provided on the opening edge of the opening 22 so as to project from the front,
A shutter guide having an opening corresponding to 2 is attached to the inner surface thereof, while the shutter 23 has a handle on the upper part, and the opening 22 can be opened and closed by sliding by the guide action of the shutter guide. Has been done. In this case, the handle of the shutter 23 may be bent to project outward from the window formed on the front wall of the storage container 21 so that the window serves as a guide portion and the window is closed by a shutter guide. preferable.

Therefore, the shutter 23 closes the opening 22 when sliding downward, and opens the opening 22 when sliding upward. In this open posture, it is preferable to attach a magnet to the front wall of the storage container 21 and hold the handle by magnetizing it.
In addition, a detent mechanism consisting of a suction cup, spring and ball,
The spring plate may be replaced with a means for elastically gripping the handle.

The chute 24 is in a first posture 24A which is in communication with the opening 22 and outflows the grain 2 out of the refrigerator, and a second posture 24B which is not in communication with the opening 22 and is on standby in the cooler air circulation space 34. The posture can be freely changed, and the first posture 24A is held by being fitted onto the guide. At this time, the first posture 24A is held at the same position as or protruding from the outlet 5 opened by the door 14 and the grain outside the storage 1. 2 can be spilled.

In the present embodiment, the take-out port 5 is large enough to allow the shutter 23 to slide and the chute 24 to change its posture from outside. Furthermore, 31 is a cooler arranged below the rear bottom of one side lower part in the storage 1.
It has a cooler, fan, temperature sensor, etc.
The temperature can be controlled by supplying cold air of 0 to 20 ° C., and preferably the inside of the storage 1 is kept at around 15 ° C.

The cooler 31 does not have a dryer and a powerful cooler, but is provided only with a mechanism for maintaining the temperature in the storage 1 at about 15 ° C. and always at a substantially constant level to minimize the atmosphere surrounding the storage container 21. The conditions are such that insects and molds do not occur, and rice is managed efficiently with inexpensive equipment. The cooler 31 is housed in a box 36, and the box 36 has an upper discharge port 36.
a and a lower suction port 36b are formed, and an upper and lower partition plate 37 extending in the left-right direction so as to divide the space therebetween is fixed,
The left and right side edges and the rear edge of the upper and lower partition plates 37 are fixed to the storage 1, and the front edge is attached to the storage container 21.

Further, left and right partition plates are provided on the left and right of the box 36 from the upper and lower partition plates 37 to the rear bottom of the storage container 21 so that the cooler air discharged from the discharge port 36a does not flow directly to the side surface of the storage container 21. Shield. Each bracket 3
3 is an angle member having an L-shaped cross section, the vertical portion of which is fixed to the storage container 21, and a large number of circular holes are formed in the horizontal portion in the longitudinal direction to form the air passage 33a.

The receiving member 35 is also an angle member having an L-shaped cross section, the vertical portion of which is fixed to the inner surface of the storage 1, and a large number of circular openings 35a in the longitudinal direction are formed in the horizontal portion.
The opening 35a is located at a position corresponding to each air passage so as not to block the cooler air from flowing vertically through the air passage. The cooler wind of the cooler 31 exits from the discharge port 36a and hits the storage container 21 at one end, and then the bracket 33 between the storage container 1 and one side surface of the storage container 21 near the cooler 31.
Of the storage container 21 from the upper side of the storage container 21 to the lower side of the storage container 1 through the air passage 33a of the bracket 33. After coming into contact with the lower side and the bottom of 21, it is sucked into the suction port 36b below the partition plate 37.

As described above, the rear bottom of the storage container 21 is a portion where the cooler air from the discharge port 36a directly hits and is guided, and the storage container 21 is locally cooled, Condensation may form inside. Therefore, it is preferable to attach a heat insulating material to the portion directly exposed to the cooler wind. In addition, if an inspection window and a door for opening and closing the storage window are provided on the side of the storage case 1, the cooler 31 can be inspected through the inspection window, and the storage container 21
Bagged grain 38 can be stored in the cooler-like distribution space 34 below.

According to the present embodiment described in detail above, the cooler air can be evenly distributed around the entire circumference of the storage container 21, the grain 2 can be stored efficiently and without causing uneven cooling, and the chute can be used. Since it can be distributed to 24, the shoot 2
It is possible to efficiently cool the leftover grains that have adhered to the 4 itself and ensure long-term storage. Further, since the chute 24 is exposed to the outside air only when the grain 2 is taken out temporarily and is exposed to the cooler air during the standby, it is possible to prevent the cooling efficiency from being extremely lowered. Further, since the grain 2 can be taken out instantaneously through the chute 24 by the shutter 23 that can be opened and closed, the outside air is prevented from entering the inside of the storage container 21, the dew condensation inside the container 21 is prevented, and the storage is maintained for a long time. Can be maintained.

Further, according to this embodiment, since the step 9 is located in front of the door 14 when the step 9 is installed, when the grain 2 is put on the step 9,
Since the door 14 is always closed and the chute 24 is housed inside the storage 1, it is possible to prevent the grain 2 from being carelessly input. The present invention is not limited to the above embodiment, and the design can be changed appropriately. For example, a weighing-out mechanism may be attached to the opening 22 of the storage container 21.
