Description

[Detailed description of the invention] Industrial application field The present invention relates to a circulating grain drying device.

Conventional technology A humidity control tank is provided inside the humidity control section located at the top, and a plurality of vertical grain drying chambers each having vertical perforated plates on both sides are provided in the drying section at the bottom of the humidity control section. A funnel section is formed in the lower half of the humidity control section to guide grains from the wide humidity control section to a narrower downward grain drying chamber, and a grain collecting section is formed below the drying section. , a receiving gutter is provided in the grain collecting section, a spiral conveyor is installed horizontally on the upper surface of the receiving gutter, an elevator is provided on the side of the machine body, and a discharge end of the spiral conveyor is connected to a lower part of the elevator; Many moisture control type grain drying apparatuses are known in which the discharge gutter at the top of the elevator is connected to a humidity control tank to perform circulation drying.

Problems to be Solved by the Invention The circulation type humidity control type grain drying device has a rotary valve installed inside the down-flow grain drying chamber formed inside the drying section, or at the lower end of the drying chamber. A large amount of straw, etc. adheres to the rotor blades and shaft parts.

In order to remove this, the conventional method was to remove the upper canopy of the drying device and enter the interior to clean the perforated plate and the rotary valve.

However, the work of removing the canopy was not only quite troublesome because there was an upper conveyor connected to the elevator, but also the footing was poor once inside the narrow humidity control tank, making it impossible to completely clean it.

Therefore, when wheat is dried after rice is dried, residual rice grains are mixed into the wheat.

Therefore, in the present invention, the structure of the lower half of the humidity control section is made into a special structure, and the inclined board forming the funnel part is opened outward to form an opening window, and the grain drying chamber is opened from the opening window. This overcomes the defects of the conventional products described above by making it possible to clean the inside.

Means for Solving the Problem Therefore, the present invention provides a humidity control tank 4 inside the humidity control section 1 at the upper position, and a drying section 2 at the lower part of the humidity control section 1.
A plurality of vertical flow-down grain drying chambers 5 each having vertical perforated plates on both sides are installed in the humidity control section 1.
A funnel part 9 is formed in the lower half for guiding the grains into the falling grain drying chamber 5 which is narrower than the wide humidity control part 1, and a grain collecting part 3 is formed below the drying part 2. A receiving gutter 16 is provided in the grain collecting section 3, a spiral conveyor 17 is installed horizontally on the upper surface of the receiving gutter 16, an elevator 19 is provided on the side of the machine body, and the discharge end of the spiral conveyor 17 is connected to the elevator 19. The lower part of the elevator 19 is connected to the upper part of the elevator 19, and the discharge gutter at the upper part of the elevator 19 is connected to the humidity control tank 4 so that circulation drying can be performed.
The funnel part 9 formed in the lower half of the humidity control part 1
The center part has a rectangular board 10 and the outer inclined board 11.
The lower end of the outer inclined board 11 is pivoted to the upper end of the falling grain drying chamber 5, and the upper end is pivoted outward to open the circulating grain drying device. It is something.

EXAMPLE To explain with the drawings, 1 is an upper humidity control section, 2 is a drying section below the humidity control section 1, and 3 is a grain collecting section below the humidity control section 1. The upper humidity control section 1 is mainly a humidity control tank 4, which is formed in a rectangular empty chamber made of a thin iron plate. A plurality of down-flow grain drying chambers 5, 5 are provided in the drying section 2 in the lower part. Both side walls of the down-flow grain drying chambers 5, 5 are formed of nets or perforated plates 6, 6. A hot air supply chamber 7 is provided between the downstream grain drying chambers 5, 5, and a hot air exhaust chamber 8 is provided outside the downstream grain drying chambers 5, 5.
8 is formed. The lower half of the humidity control section 1 is formed into a funnel section 9 . The funnel portion 9 is formed by a square-shaped board 10 at the center and an inclined board 11 at the outside. The outer inclined board 11 is a down-flow type grain drying room 5
A shaft 12 is fixed to the upper end of the perforated plate 6 of
Tightened with 4. A normal drying device has a funnel part 9.
However, the present invention does not have a side plate. The upper ends of the down-flow grain drying chambers 5, 5 are connected to the lower ends of the funnel portion 9, respectively. Rotary valves 15, 15 are attached to the lower ends of the down-flow grain drying chambers 5, 5, respectively. A V-shaped receiving trough 16 is provided in the grain collection section 3 at the lower part of the drying section 2. The lower side of the rotary valves 15, 15 is
It is surrounded by the V-shaped receiving gutter 16. The V-shaped receiving trough 16 slopes lower toward the center, and a spiral conveyor 17 is horizontally installed above it.

In addition, 18 in the figure is a control box, 19
20 is an elevator, 20 is an upper conveyor, 21 is a burner, and 22 is a suction fan.

Effect Next, we will discuss the effect.

When undried rice is loaded into the loading hopper of the elevator 19, it rises inside the elevator 19 and then passes through the upper conveyor 20 from the discharge gutter into the humidity control tank 4 and the down-flow grain drying chambers 5, 5. be included. Then, when the burner 21 is ignited and the suction fan 22 is rotated to supply hot air from the hot air supply chamber 7 into the down-flow grain drying chambers 5, 5, the paddy rice in the down-flow grain drying chambers 5, 5 is exposed to the hot air. A portion of the surface tissue is dried. When the rotary valves 15, 15 are rotated at a constant cycle, the dried unhulled rice is fed out little by little by the rotation of the rotary valves 15, 15, and is discharged onto the V-shaped receiving trough 16, and then transferred to the spiral conveyor 17. It is transported horizontally and flows into the lower end of the elevator 19, and the elevator 1
It rises again in the humidity control tank 4 and is returned to the humidity control tank 4. As the work continues, the stacked unhulled rice is dried for a second time in the down-flow grain drying chambers 5, 5, and then stacked in the humidity control tank 4 again. When this drying is repeated about 4 to 6 times, the humidity control drying is normally completed.

However, when the above-mentioned humidity control drying is completed, a large amount of straw waste etc. sticks to the perforated plates 6, 6 forming the down-flow type grain drying chamber 5, and the rotary valves 15, 15.
The bolts and nuts 1 that secure the outer inclined panel 11 may become entangled with the wing pieces or shaft of the
When loosening and removing 4 and opening the inclined board 11 outwards around the shaft fitting 12, the funnel part 9 will form a large opening, so insert your hand through the opening using a shovel or the like to clean it. It is something to do.

Effects A humidity control tank is installed inside the humidity control section, which is conventionally located at the top, and multiple vertical grain drying chambers with vertical perforated plates on both sides are installed in the drying section at the bottom of the humidity control section. A funnel section is formed in the lower half of the humidity control section to guide grains from the wide humidity control section to a narrower downward grain drying chamber, and a grain collecting section is formed below the drying section. , a receiving gutter is provided in the grain collecting section, a spiral conveyor is installed horizontally on the upper surface of the receiving gutter, an elevator is provided on the side of the machine body, and a discharge end of the spiral conveyor is connected to a lower part of the elevator; Many moisture control type grain drying apparatuses are known in which the discharge gutter at the top of the elevator is connected to a humidity control tank to perform circulation drying.
