[Industrial application fields]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure between storage bins of a dry storage preparation facility for grains, and in particular, a dry storage preparation facility for grains that facilitates the discharge of straw, dust, and the like that accumulates in a corridor provided at the upper part of a passage between the storage bins Relates to the structure between the storage bins.
[0002]
[Prior art]
In recent years, various forms of dry storage preparation facilities for grains have been widely used, where grains from individual farmers are collected, stored dry, processed such as hulling, and then shipped. . FIG. 4 and FIG. 5 show an example, and in this example, there is provided a grain carry-in section comprising a load receiving hopper 1 for picking up grains, a load receiving lift 2, a relay conveyor 3, a coarse sorter 4, a weighing machine 5 and the like. Further, on the carry-out side, there is provided a grain carry-out section comprising an adjustment tank 6, a hulling machine 7, a swing sorter 8, a shipping tank 9, and the like, and there are a large number of storage bins 10 serving both as grain drying and storage. Be placed.
[0003]
In the illustrated example, the storage bins 10 are arranged in two series in parallel in a state of being adjacent to each other, and the received grain is weighed for each predetermined amount, and then a predetermined storage bin is supplied from the bin loading elevator 11 via the top conveyor 12. 10 in turn. As the storage bin 10, a rectangular storage bin is often used, and an air conditioner 13 and a blower 14 are arranged in each storage bin group.
[0004]
Each storage bin group has an air duct 15 for dehumidified air at the lower part thereof, and the dehumidified air supplied from the blower 14 enters the storage bin 10 through the air duct 15 and dries the grains. Grains after the drying process are stored in the storage bin 10 as they are, taken out from the discharge hopper 16 formed on the floor surface of the storage bin 10 when necessary, and sent from the discharge conveyor 17 to the above-mentioned carry-out side.
[0005]
FIG. 2 shows a cross section of the storage bin 10 portion in the grain processing apparatus as described above. The storage bin groups in two rows are arranged in parallel with the passage portion 20 therebetween, and a roof portion 30 is provided above. It is done. In addition, 31 is an exhaust port. The passage portion 20 is necessary for inspection of the discharge hopper 16 and the discharge conveyor 17, and the operator goes in and out as necessary even during operation of the grain processing apparatus. Above the passage portion 20 is provided a corridor 21 used for inspection of grains in the storage bin 10 and the operator enters and exits the corridor 21 as needed while the apparatus is in operation. Reference numeral 22 denotes a handrail for pedestrian safety.
[0006]
The floor surface 10a of each storage bin 10 is substantially horizontal, and there are innumerable small air supply holes 19 in the direction of the discharge hopper 16, and the discharge of grains from the storage bin 10 is performed by the air supply holes. This is performed using wind force from the blower 14 blown out from the air blower 19. As described above, the grain discharged from the discharge hopper 16 is transported to the adjustment tank 6 via the discharge conveyor 17, and then sequentially passes through the grain unloading section and is transported outside the facility. In the process, relatively light rice cake (no rice cake) and garbage mixed in the grain are removed from the facility by the wind separator 18 interposed in the middle of the route, and only the husks are shipped.
[0007]
In such a facility, an operator enters and exits both of the passage portion 20 and the walkway 21 even when the facility is in operation, and dust or the like does not fall from the walkway 21 to the worker in the passage portion 20. Thus, conventionally, the corridor 21 is usually made of a blank plate, that is, a plate material having no openings or gaps.
[0008]
[Problems to be solved by the invention]
Along with the modernization of farming, this type of dry storage preparation facility for grains has also increased in size, and a drying facility with a large flow rate has been incorporated to process a large amount of grains in a short time. It is coming. Along with this, an improvement in the ability to discharge grains from the storage bin 10 is also required. As described above, the grain is discharged from the storage bin 10 using the wind force from the air holes 19 formed in the floor surface 10a. If a large amount of grain is discharged within a limited time, a large amount of air is discharged. Needs to be ejected from the air supply holes 19.
[0009]
In the case of conventional relatively small dry storage preparation facilities for grains, the amount of air required for grain discharge is relatively small, and the relatively light weight of straw and garbage mixed in grains However, even if soaring, most of it falls again into the storage bin, and finally it is discharged together with the grain from the grain hopper. It did not accumulate on structures such as walkways, and even if deposited, it did not become a major obstacle.
[0010]
However, as the facility becomes larger as described above, when a large amount of air is sent to discharge the grain, the amount of residual grain in the bin is small as in the storage bin group on the left side of FIG. As the distance increases, soot and garbage rise upward from the storage bin 10, and a phenomenon occurs in which the deposit G accumulates on the corridor 21 as shown in FIG. The soot and garbage accumulation G accumulated on the walkway is not discharged along with the grain discharge, and remains on the walkway even after the discharge work is completed. For this reason, after the operation of the facility is completed or during the operation, the worker goes up on the corridor, and the bags and garbage accumulated manually are packed in a bag and carried downward.
[0011]
For the purpose of reducing the work, as shown in FIG. 3, a cleaning hopper 23 is attached to a part of the corridor 21, and a chute 24 reaching the ground surface is piped on it, and then the ridges and dust G on the corridor 21 Is placed in the hopper 23 and packed underneath, or a vacuum cleaner is arranged in the corridor, and a bag or dust is sucked and discarded by the vacuum cleaner.
[0012]
Both of these methods require manpower to eliminate dredging and garbage, and also require special equipment, resulting in a rise in cost and newly occurring as the scale of the dry storage preparation facility for grains is increased. It has been regarded as a problem to be solved.
An object of the present invention is to solve the above-mentioned problems that have occurred with the increase in the scale of a dry storage preparation facility for grains, and more specifically, a slight improvement over the conventional dry storage preparation facility for grains. For grain, it is possible to return most of the blown up dust and garbage to the storage bin without adding up soot and dust on the corridor provided above the passage between the storage bins. It is to provide a structure between the storage bins of a dry storage preparation facility.
[0013]
[Means for Solving the Problems]
The structure between the storage bins of the dry storage preparation facility for grain according to the present invention for solving the above-described problem is a member having a large number of gaps such as an extended metal, for example, a walkway provided above the passage portion between the storage bins. And an inclined plate that guides the fallen object passing through the gap into the storage bin is disposed in the lower part of the corridor.
[0014]
[Action]
With the above configuration, a large amount of air is sent when the grain is discharged from the storage bin, and light items such as straw and garbage mixed in the grain are blown up on the storage bin, and after floating, fall on the corridor Even if it does, since the walkway is formed with the member which has many gap | intervals like an extended metal, it passes there and falls below, without staying on a walkway. An inclined plate is disposed in the lower part of the walkway, and the dropped bags and dust fall further on the guide plate and are returned to the storage bin.
[0015]
As a result, most of the blown up slag and garbage can be returned to the storage bin, discharged together with the grain from the storage bin, and removed outside the facility by a wind separator installed in a subsequent process. This eliminates the need for manpower to remove accumulated soot and trash, and eliminates the need for hopper placement and the use of a vacuum cleaner as in the past, reducing both facility installation costs and operating costs. It becomes possible.
[0016]
【Example】
Hereinafter, the structure between the storage bins of the dry storage preparation facility for grains will be described in more detail based on examples.
FIG. 1 shows an embodiment of a structure between storage bins of a dry storage preparation facility for grain according to the present invention, except for the configuration of a walkway provided above the passage portion 20 and an inclined plate provided therebelow. Is the same as that of the grain dry storage preparation facility described above with reference to FIG. 2, and the same members are denoted by the same reference numerals and the description thereof is omitted.
[0017]
In this embodiment, the walkway 21 is not a blank board, but is formed of a plate member 31 having a large number of gaps 30 such as an expanded metal. Further, the upper end portions of the side walls 32, 32 of the storage bins 10, 10 on the side of the passage portion 20 are inclined portions 33, 33 that are inclined toward the passage side over the entire length of the storage bin group. Are joined to each other immediately below the plate member 31.
[0018]
In the above-described configuration, for example, when taking out the grain, a light quantity such as straw and garbage mixed in the grain is blown up onto the storage bin 10 due to a large amount of air sent from the blower, and a part of it is a walkway. Even if it falls to the top 21, the soot, dust, etc. pass through the gap 30 of the plate member 31 and fall downward, and then are guided by the inclined portion 33 at the upper end portion of the side wall 32 on the passage portion 20 side of the storage bin 10. And returned to the storage bin 10.
[0019]
As a result, soot and dust do not accumulate on the plate member 31 on the walkway 21 and the cleaning work becomes easy, and all the soot and dust mixed in the grain can be eliminated by wind-selection work in the subsequent process. It becomes.
The above description is one embodiment of the structure between the storage bins of the grain dry storage preparation facility according to the present invention, and there are many other variations. First, what is shown in FIG. 4 and FIG. 5 as a dry storage preparation facility for grains is merely an example, and the structure between the storage bins of the present invention has a plurality of storage bin groups across the passage, a rice center, It will be easily understood that the present invention can be applied to all conventionally known grain drying facilities and grain storage facilities such as country elevators.
[0020]
Moreover, the board member 31 which comprises a corridor is not restricted to an extended metal, On condition that an operator can walk on it, it is a perforated board like a punching metal, a perforated synthetic resin board, a perforated wood material, etc. It may also be a braided wire.
The inclined plate that guides fallen objects such as jars and dust into the storage bin is not integrated with the side wall of the storage bin as in the illustrated example, and may be configured as a separate member, and the inclination direction is also illustrated. In this case, the shape may be inclined only to the side of one of the storage bins instead of the mountain shape.
[0021]
【The invention's effect】
With the above configuration, according to the present invention, by adding a simple configuration, it is possible to prevent soot and dust from accumulating on the corridor, and it is possible to reduce the operating cost as well as the installation cost of the facility.
