Description

[Detailed description of the invention] [Industrial application field] This invention relates to grain drying equipment.

[In order to dry a large amount of paddy that is brought in at once, which the prior art and the invention aim to solve, conventional dryers have multiple grain drying devices installed in parallel, and a common long loading conveyor and discharge conveyor. Because of this, a large number of pillars were required to support the middle part of the conveyor. This obstructs work and increases costs.

[Means to solve the problem]

In order to solve such technical problems, the technical means of the present invention includes a storage section 1, an aeration drying section 2 that applies drying air to the grains flowing down from the storage section 1, and a circulation mechanism section such as an elevator. A plurality of grain drying devices each having a cooling tank 5 placed in a grain drying section 4 consisting of are arranged vertically in parallel, and the discharge conveyor 31 and the loading conveyor 38 are supported by the elevator 14 and the machine frame part 32 of the main body of the grain dryer. That's true.

[Operation and effect of the invention]

This invention utilizes the space between the main body of the grain dryer and the elevator in the circulation mechanism to provide a discharge conveyor and a tension conveyor that are long in the transfer direction above and below. Since it is supported by the machine body side and the elevator, there is no need for complicated footwork to support the conveyor as in the past, and work space for inspections etc. can be secured, making the work easier and a few things easier. This will lead to cost reduction as only one supporting part is required.

are connected.

The dried grains from the discharge conveyor 31 are sent to the hulling device 1C.
The supply is transported to.

The hulling bag WC is of a known form and consists of a hulling section, a paddy/brown rice sorting section, and the like. A weighing device is disposed on the brown rice outlet side of the paddy/brown rice sorting section, and the rice is packed into bags according to a predetermined weight.

Next, the operation of the embodiment will be explained.

Grain harvested in the field, such as paddy, is transported by truck, etc.
Load it into receiving hopper A. The grains received in the receiving hopper A are lifted up by an elevator 42 and supplied to the starting end side of the tensioning conveyor 38.1 The grain drying device B to which the grains are to be tensioned is determined by selection control from a control room (not shown). When designated and the tensioning switch is turned ON, a predetermined tensioning on-off valve 40 opens, and the grains transferred by the tensioning conveyor 38 are tensioned and supplied into the specified drying bag fiB.

Regarding this specified grain drying device B, the grain drying section 4
The grains loaded in the storage section 1 flow through the ventilation drying section 2 and receive hot air through the grain flow passage 6, and then pass through the delivery valve 11.
, 11 . . . and transferred to the elevator 14 by the transfer spiral 12.

The switching valve 16 is set in advance so that the grain can be supplied to the first opening part A side (Fig. 2), and the grain is transferred to the communication pipe 17 and the transfer gutter 1.
9 and is returned to the reservoir 1 where it is subjected to a refining action. Then, such drying and tempering actions are repeated, and when the finishing moisture value is reached, drying is completed.

The grains that have undergone such a circulation drying process are transferred into the cooling tank 5. That is, the switching valve 16 is switched so that the grain can be fed to the lower side of the second opening, and the grain is fried by the elevator 14.
Cooling tank 5 placed on top of the frame of the four grain drying units
The grains inside are uniformly introduced via a rotating spreader plate 23 through a transfer [21]. After being left to cool for a predetermined time, the discharge spirals 25 and 25 are driven to flow down the inclined guide section 24 and are transferred by the discharge transfer@26, 26, and are supplied and dropped onto the discharge conveyor 31 surface via the guide chute 30. The paddy is transported by W! It is sent to device C.

In this embodiment of the grain dryer with such a circulation process, the space between the main body of the grain dryer and the elevator 14 is effectively utilized to provide the discharge conveyor 31 and the tension conveyor 38, which simplifies the structure. be done. That is, one side of the box-shaped frame part 33 of the discharge conveyor 31 is fixed to the machine frame part 32 of the dryer main body with an L-shaped mounting plate 34 via screws 35, and the other side of the box-shaped frame part 33 is fixed to the machine frame part 32 of the dryer main body. It is fixedly supported by inserting a letter-shaped hook 36 into an insertion plate 37 provided on the elevator 14. Further, a tensioning conveyor 38 is disposed in parallel below the discharge conveyor 31, and the tensioning conveyor 38 is attached to a box-shaped frame portion 33 of the discharge conveyor 31 through an L-shaped mounting plate 34 with a screw 35. Furthermore, only the sides of the dryer main body are firmly fixed with screws 35 via L-shaped mounting plates 34, so there is no need for pillars to support both conveyors 31 and 38. Become. Therefore, the main body of the dryer, the discharge conveyor 31, and the loading conveyor 32 are integrated into a paddy conveyance system, and the structure is simplified.

Moreover, the discharge conveyor 31. Since the pedestals that supported the stake conveyor 38 are no longer needed, inspection and cleaning work near the dryer itself is easier, and grain can be transported to the vicinity of the dryer using a transport vehicle such as a truck. can do 2
The space has been increased by the amount of pillars, making inspections and other tasks easier.

In this embodiment, since the discharge conveyor 31 is installed on the loading conveyor 38, circulation can be performed smoothly when grain is loaded from the receiving hopper A to the storage section 1 of the grain drying device B. Moreover, when the drying process is completed and the grains are left to cool in the cooling tank 5 and then sent to the discharge conveyor 31, the grains can be easily discharged from the cooling tank 5 by gravity.

Furthermore, as in this embodiment, by suspending the tension conveyor 38 from the discharge conveyor 31 supported by the machine frame 32 and the elevator 14, different conveyors 31 and 38 on the left and right sides can be supported. This is advantageous when
