2. Description of the Related Art In recent years, various types of grain dry storage and preparation facilities have been constructed in which grains from individual cultivators are collected, dried and stored, and after necessary processing such as hulling and necessary preparation and shipment. Is becoming popular. 4 and 5 show an example thereof, and in this example, the cargo receiving hopper 1 for collecting grain,
Consignment elevator 2, relay conveyor 3, rough sorter 4, weighing machine 5
And a grain carry-out section including a regulating tank 6, a grain huller 7, a swing sorter 8, a shipping tank 9, and the like, and a grain drying and storage section between them. A large number of storage bins 10 that also serve as are arranged.

In the illustrated example, two storage bins 10 are arranged in parallel in a state of being adjacent to each other, and the received grain is weighed by a predetermined amount, and then a predetermined amount is fed from the bin feeding elevator 11 via the top conveyor 12. Storage bin 10
Are sequentially put into. A rectangular storage bin is often used as the storage bin 10, and an air conditioner 13 and a blower 14 are arranged in each storage bin group.

Each storage bin group has an air duct 15 for dehumidified air in the lower part thereof, and the dehumidified air supplied from the blower 14 passes through the air duct 15 and is stored in the storage bin 10.
Go inside and dry the grain. The grain after the drying process is stored in the storage bin 10 as it is, and the storage bin 1 is stored when necessary.
It is taken out from the discharge hopper 16 formed on the floor surface of 0,
It is sent from the discharge conveyor 17 to the unloading side.

FIG. 2 shows a cross section of the storage bin 10 portion in the grain processing apparatus as described above. The storage bin groups forming two rows are arranged in parallel with the passage portion 20 interposed therebetween, and the roof portion is provided above. 30 is provided. In addition, 31 is an exhaust port. The passage portion 20 includes a discharge hopper 16 and a discharge conveyor 17.
It is necessary for inspections, etc., and workers come and go as needed even while the grain processing apparatus is in operation. A walkway 21 used for inspection of grains in the storage bin 10 and the like is provided above the passage portion 20, and an operator enters and exits on this walkway 21 while the apparatus is in operation as necessary. In addition, 2
Reference numeral 2 indicates a handrail for the safety of pedestrians.

The floor surface 10a of each storage bin 10 is substantially horizontal, and innumerable small air supply holes 19 are formed in the storage hopper 16 toward the discharge hopper 16 to discharge the grain from the storage bin 10. This is performed by using the wind force from the blower 14 blown out from the air supply hole 19. As described above, the grain discharged from the discharge hopper 16 is conveyed to the adjustment tank 6 via the discharge conveyor 17, and thereafter sequentially passes through the grain discharge section and is conveyed to the outside of the facility. In the process, the relatively light slag (the paddy without the contents) and the dust mixed in the grain are removed to the outside of the facility by the wind sorter 18 interposed in the middle of the route, and only the husks are shipped.

[0007] In such a facility, workers enter and leave both the aisle 20 and the corridor 21 even when the facility is in operation, so that workers in the aisle 20 can enter the garbage, etc. from the top of the corridor 21. Conventionally, the corridor 21 is usually made of a blind plate, that is, a plate material having no openings or gaps so that the particles do not drop.

[0008]

With the modernization of agricultural work, the number of large-scale dry storage / preparation facilities for this type of grain is increasing, and a large flow rate is required to process a large amount of grain in a short time. The drying facilities that it has are becoming more common. Along with this, improvement in the ability to discharge grains from the storage bin 10 is also required. Storage bin 1 as described above
The discharge of the grain from 0 is the air supply hole 19 formed in the floor surface 10a.
When a large amount of grain is to be discharged within a limited time, it is necessary to eject a large amount of air from the air supply hole 19 by using the wind force from the.

In the case of a conventional relatively small-scale dry storage and preparation facility for grains, a relatively small amount of air is required at the time of grain discharge, and a relatively lightweight powder mixed in the grains is used. Most of the dust and dirt are not soared due to the air supply during grain discharge, and even if they are soared, most of them fall into the storage bin again and are finally discharged from the grain hopper together with the grains, which is then selected in the post-process. It was discharged to the outside of the facility due to the fact that it was not deposited on structures such as corridors, and even if it was deposited, it did not cause a major obstacle.

However, as described above, when the facility is enlarged and a large amount of air is sent to discharge the grain, the residual grain in the bin like the storage bin group on the left side of FIG. Storage bin 10 for waste and garbage
2, the phenomenon of accumulation as an aggregate G on the corridor 21 is occurring as shown in FIG. The aggregate G of dust and dirt accumulated on the corridor is not discharged together with the grain discharge, and remains on the corridor even after the discharge work is completed. To that end, workers climb up the corridor after or during the operation of the facility,
Bags are used to pack the dust and dirt accumulated by human power and to carry it downward.

In order to reduce the work, as shown in FIG. 3, a hopper 23 for cleaning is attached to a part of the corridor 21, and a chute 24 reaching the ground surface is piped there, and
There is also a method in which the dirt and dust G on the corridor 21 is put into the hopper 23 and is packed in the bottom, or a vacuum cleaner is arranged in the corridor, and the dirt and dust are sucked and discarded by the vacuum cleaner. ing.

[0012] In any of these methods, labor is required for the work of removing dust and dirt, and special equipment is also required, resulting in a sharp rise in cost, and with the increase in the scale of the grain dry storage and preparation facility. It has been regarded as a new issue to be solved. An object of the present invention is to solve the above-mentioned problems caused by the increase in the scale of a grain dry storage and preparation facility, and more specifically, a slight improvement to the conventional grain dry storage and preparation facility. Grains that prevent the accumulation of dust and dirt on the corridor provided above the passage between storage bins and can return most of the blown dust and dust to the storage bin. It is to provide a structure between storage bins of a dry storage preparation facility.

[0013]

The structure between the storage bins of the dry storage and preparation facility for grains according to the present invention for solving the above-mentioned problems is as follows. Is formed by a member having a large number of gaps, and an inclined plate for guiding a fallen object passing through the gaps into the storage bin is arranged at the lower part of the corridor.

[0014]

With the above structure, a large amount of air is blown when the grain is discharged from the storage bin, and lightweight materials such as dust and dirt that have been mixed in the grain are blown up onto the storage bin and floated. Even if the corridor is dropped upward, the corridor is formed of a member having a large number of gaps, such as an extract band metal, so that the corridor does not stay on the corridor and passes through the corridor and drops downward. An inclined plate is placed at the bottom of the corridor,
The dropped dust, dirt and the like further fall on the guide plate and are returned to the storage bin.

As a result, most of the blown dust and dirt can be returned to the inside of the storage bin, discharged together with the grain from the storage bin, and removed outside the facility by the wind separator installed in the subsequent process. . This eliminates the need for manpower to remove accumulated dirt and dust, and eliminates the conventional arrangement of hoppers and the use of a vacuum cleaner to eliminate waste, reducing facility installation costs and operating costs. It will be possible.

EXAMPLES The structure between the storage bottles of the grain dry storage and preparation facility will be described in more detail with reference to examples. FIG. 1 shows an embodiment of the structure between the storage bins of the grain dry storage and preparation facility according to the present invention, except for the configuration of the corridor provided above the passage 20 and the inclined plate provided below it. Is similar to that of the dry storage and preparation facility for grains described above with reference to FIG. 2, and the same members are denoted by the same reference numerals and the description thereof will be omitted.

In this embodiment, the corridor 21 is not a blind plate, but is formed by a plate member 31 having a large number of gaps 30 such as extract band metal. Further, the upper ends 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 directly below the plate member 31.

With the above-mentioned structure, for example, when the grain is taken out, a small amount of air blown from the blower blows up the lightweight materials such as dust and dirt mixed in the grain onto the storage bin 10 and blows it up. Even if the portion falls onto the corridor 21, the dust, dust, etc. pass through the gap 30 of the plate member 31 and fall downward, and then the inclined portion of the upper end of the side wall 32 of the storage bin 10 on the side of the passage portion 20. It is guided by 33 and returned to the storage bin 10.

As a result, dirt and dust will not be deposited on the plate member 31 of the corridor 21, facilitating cleaning work, and all dirt, dirt, and the like mixed in the grain will be picked up in the subsequent process. Can be eliminated by. The above description is of one embodiment of the structure between the storage bins of the grain dry storage and preparation facility according to the present invention, and there are many other variations. First, the dry storage and preparation facility for grains shown in FIGS. 4 and 5 is merely an example, and the structure between the storage bins of the present invention is a rice center having a plurality of storage bin groups with a passage in between. It will be easily understood that it can be applied to all conventionally known grain drying facilities and grain storage facilities such as country elevators.

Further, the plate member 31 constituting the corridor is not limited to the extract band metal, but a perforated plate such as punching metal, a perforated synthetic resin plate, and a perforated wood material, provided that an operator can walk on the plate member 31. It may be a material or the like, or may be a braided wire material. The inclined plate that guides falling objects such as dirt and dust into the storage bin is not integrated with the side wall of the storage bin as in the illustrated example, but may be configured as a separate member, and its inclination direction is also illustrated. It is not limited to the mountain shape, and may be inclined only to one storage bottle side.

[0021]

As described above, according to the present invention, it is possible to prevent deposits such as dust and dirt on the corridor by adding a simple structure, and to reduce the installation cost of the facility and the operating cost. Is possible.
