Description

[Detailed Description of the Invention] Industrial Application Field The present invention enables the receiving operation to be quickly completed with a short waiting time, no matter how large the amount of individual grains brought into a communal drying facility. The present invention relates to a cargo receiving device in a communal drying facility that can be used for drying.

Conventional technology Traditionally, grains harvested by each farmer were collected and put into a receiving hopper installed in a communal drying workshop.
The grains are sequentially supplied to multiple dryers and dried to the desired moisture level, and then the dried grains are transported to the next adjustment processing process where they are hulled and sorted, and then rice with the desired moisture level is dried. A common drying facility designed to obtain this is well known, having been described in, for example, Japanese Utility Model Publication No. 52-26392 prior to the filing of this application.

In addition, in the above-mentioned communal drying facility, when the amount of grain individually brought in by each farmer is larger than the capacity of the receiving hopper, the brought-in grain is temporarily stored and stored, thereby minimizing the farmers' waiting time for receiving the cargo. Container-type grain containers for reducing the number of grains were also disclosed before the present application, for example, in Japanese Utility Model Application Publication No. 51-109052 and Japanese Utility Model Application Publication No. 1989-109052.
They are described in Japanese Patent No. 51-146283 and are well known.

Problems to be Solved by the Invention Incidentally, the grain containers used in the above-mentioned known communal drying facilities are molded to a size that can accommodate a considerable amount of grain, and there are many grain containers in the communal drying facility. Because there is not enough open space to set up grain bins, when the amount of grain brought in exceeds the capacity of the receiving hopper, the excess grain is usually dumped into grain bins outside of the joint drying operation. The grain containers are stored and placed on top of each other outside the work area, and then, once the loading work of the grain previously stored in the receiving hopper is completed, the grain container is transported by a forklift, loaded onto the receiving hopper, and then placed on top of the receiving hopper. This involved receiving shipments over and over again.

Therefore, according to the conventional cargo receiving operation, the grain containers were installed outside, which caused many inconveniences during rainy days, etc., and required the work of transporting a large number of grain containers one by one using a forklift. However, the amount of work required by the operator increases, and labor saving cannot be achieved easily, and an expensive forklift must be provided. Therefore, the present invention provides that, when grains exceeding the storage capacity of the receiving hopper are brought into a communal drying facility, a large number of grain storage tanks capable of storing the grains under a suction ventilation condition are used for communal drying. Each grain stored in the above-mentioned large number of grain storage tanks arranged in parallel in the workshop can be sequentially transported via a transport conveyor and a transfer conveyor that are suspended in a pit directly below the grain storage tank and receiving hopper. In this way, it is possible to reduce the waiting time for farmers to receive cargo as much as possible, reduce the amount of work required by workers, and achieve labor savings, as well as to safely store grain and prevent dust from scattering around when grain is brought in. The above problem has been solved by providing a cargo receiving device in a communal drying facility that can perform sanitary communal drying work.

Means for Solving the Problem Therefore, the technical problem of the present invention is that even when grains in excess of the capacity of the receiving hopper are brought into the communal drying facility, the grains brought in can be immediately treated without deteriorating their quality. To obtain a cargo receiving device in a communal drying facility that can safely accommodate cargo, shorten the waiting time at the time of receiving cargo, reduce the amount of work by workers, and further improve the environment in the drying workplace. be.

In order to solve this technical problem, the structure was modified such that a large number of grain storage tanks for storing brought-in grains under suction and aeration were installed in parallel in a communal drying workshop, and a large number of grain storage tanks were discharged. The transport conveyors are arranged to face the transport conveyors suspended in the pit, and the transport end side of the transport conveyors is arranged to face the supply start end side of the transfer conveyor suspended in the pit directly below the receiving hopper. This is a cargo receiving device in a communal drying facility that is characterized by:

Effect The above technical means acts as follows. (Refer to the drawing) Now, the grains harvested by each farmer are transported to the communal drying workshop and are sequentially collected and deposited into the receiving hopper 7. If the amount of grain brought in individually is larger than the storage capacity of the receiving hopper 7, the excess grain is stored in a plurality of grain storage tanks 8 arranged side by side in the communal drying workshop 1. to maintain the aeration condition.

In this way, no matter how much more grain is brought in than the capacity of the receiving hopper 7, each farmer can immediately put it into the grain storage tank 8 and return home in a short time without having to wait for receiving the cargo. Is it possible to do that?
Since the grains stored in each grain storage tank 8 are stored under suction and aeration conditions, they can be stored without any deterioration, and even in rainy weather. In addition to not causing any inconvenience, it is possible to quickly complete the receiving work while preventing dust from scattering to the surrounding area at the time of loading.

When the grain loaded into the receiving hopper 7 is first loaded into the dryer 28 via the transfer conveyor 19, the grains placed in the receiving hopper 7 are loaded into the dryer 28. Conveyor 20 transfers the grains stored in
9, the conveyed grains are transferred to a large number of dryers 29 one after another by the transfer conveyor 19 as before, and as the dryers 29 start operating, the grains are finished to a predetermined moisture level and dried. At the same time, the rice can be hulled and sorted to produce rice with a desired moisture content.
