Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dryer configured to dry grains using hot air generated by a burner when the grains pass through a drying chamber.

In this type of dryer, the grains flowing down the drying room are collected from the grain conveyor at the bottom of the machine to the grain lifting device installed on the rear of the machine, and the grains are hoisted to the top of the machine by the grain lifting device. Generally, the grains are structured to flow down the drying chamber again, and as in Utility Model Publication No. 48-41017, the loading hopper for loading the grains into the machine body is installed toward the bottom of the grain lifting device. There are those that are installed to open, and those that have a hopper installed on the left and right sides of the machine so that it extends toward the grain hopper at the bottom of the drying room.Also, the burner is usually attached to a grain lifting device. It is installed at the bottom of the machine at a position opposite to the installation side of the hopper and its vicinity.

When installing a dryer in a barn, the burner must be placed a certain distance from the wall on one side of the barn to prevent fires. The distance between the device and the staking hopper and the wall on the other side of the barn has to be small, making it difficult to perform staking work on the staking hopper.

Therefore, in this invention, a loading hopper for loading grain into a grain collecting chamber provided in communication with the lower part of the grain lifting device is protruded from the outside of the machine near the outside of the burner installation location. When installed in a barn, the rear side of the dryer body (opposite the burner and stake hopper) is attached to one wall of the barn.
By placing the hoppers and burners close enough together, the working side of the staking hopper and burner can be placed at a sufficient distance from the other wall of the barn, allowing for staking work, burner ignition, and adjustment. It has been devised so that the work can be carried out easily and with plenty of space at hand.

To explain the specific structure based on an example shown in the drawings, a funnel-shaped storage hopper 2 is installed at the top of the body 1 of the dryer.
a, 2b... are arranged in parallel along the longitudinal direction of the machine body 10, and a mesh or a One or more drying chambers 4a, 4b... formed in the shape of a flat rectangular passage using a perforated plate or the like communicate with each other, and the drying chambers 4a, 4b...
Digit rotary valves 5a, 5b...
By rotating, the speed of the grains flowing down the drying chamber 4a is adjusted, and the grains are scraped toward the rear of the machine body 1 by the grain conveyor 6 provided at the bottom of the grain collection chamber 3. The grain is lifted to the top of the aircraft 1 by the grain lifting device 7 installed on the rear of the aircraft 1,
The grains discharged from the spreading conveyor 8 extending from the grain lifting device 7 to the upper center of the storage hopper 28 are spread by the spreading fan 9 into the storage hopper 2a, and also at the front lower part of the machine body 1. While embedding the hot air outlet 11 in the drying chamber 4a + 4b, the hot air outlet 11 is exposed to the front of the air passage 10 surrounded by the drying chambers 4a and 4b, and the outer surface of the drying chamber 4a or 4b and the fuselage 1 are A suction fan 14 is provided in the suction tube opening 13 that communicates with the rear of the suction passages 12a and 12b formed by the outer plates, respectively, and the combustion gas generated from the burner 15 provided in the hot air discharge tube opening 11 is discharged as hot air. It mixes with the outside air sucked from the rear opening end 11a of the tube mouth 11 to form hot air, which is sucked by the suction fan 14 and sent from the ventilation passage 10 to the left and right drying chambers 4.
The grains flowing down inside the drying chambers 4a and 4b across the a and 4b are dried, and the exhaust gas that has reached the suction passages 12a and 12b is sent to the atmosphere through the suction pipe opening 13 at the rear of the machine body 1 by the suction fan 14. To explain based on one embodiment applied to a gravity flow type dryer, a loading hopper 16 for loading grain into the machine body 1 has its upper part 16a connected to the hot air outlet 11. The lower opening end 16b of this staking hopper 16 is positioned close to the rear opening end 11a.
is attached to the machine body 1 so as to look above the feeding start end 3a of the grain collecting room 3.

Here, if the staking hopper is removably attached to the fuselage 1 using a mounting bolt or a removable hinge, then if this staking hopper is removed after the staking work is completed, the hot air discharge tube can be removed. Since the rear part of the burner 11 can be made wider, it becomes convenient for adjusting the burner 15 to adjust the firepower.

Also, although not shown in the drawings, even in models that have a burner and a hot air outlet on the rear of the machine on the same side as the grain lifting device, the tension hopper is located behind the hot air outlet as in the above embodiment. By providing this, it is possible to reduce the unnecessary amount of protrusion of this loading hopper from the front or rear side of the machine, and it is also possible to directly load grain into the grain collection room, so it is possible to reduce the amount of waste in protruding the loading hopper from the front or rear of the machine. This can shorten work time.

Although not shown in the drawings, the device of the present invention can also be applied to a dryer having a structure in which the hot-air discharge nozzle protrudes rearward and outward from the front lower part of the body. Although the total length of the dryer is longer than that shown in the above-mentioned example, it is possible to perform the grain loading operation just as efficiently.

The grain filling device according to the present invention is configured as described above, and the grain filling hopper 16 is provided protruding outside the machine body 1 near the outside of the installation location of the burner 15. When installing a dryer in a barn, if the rear side of the machine is brought close enough to the wall on one side of the dryer, the work side, where the hopper 16 and burner 15 are installed, will be placed on the other side of the barn. Since the position is sufficiently far from the wall, it is now possible to carry out stakeout work, ignition of the burner 150, and adjustment work easily and with plenty of space at hand.

Since the grains are loaded into the grain hoisting device 7 via the grain collecting room 3, it is necessary to load them into the hoisting hopper 16 little by little over time in accordance with the grain hoisting capacity of the grain hoisting device 7. There is no such inconvenience, and even if the grain is loaded into the grain hopper 16 all at once, the lack of lifting capacity will be fully absorbed by the grain collecting room 3, The work became easier.
