BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain detection device for a grain dryer.

[0002]

2. Description of the Related Art In the conventional grain dryer, the grains stored in the upper grain storage chamber formed by the front / rear and left / right machine walls are While being fed and circulated from the chamber to the lower grain drying chamber, the hot dry air from the burner passes through the drying chamber,
When exposed to this dry hot air and dried, the grain moisture during drying is the same as the finishing target moisture, or when the grain moisture is below, the dryer is automatically stopped and the grain is dried. Is stopped.

During the grain loading operation in the first stage of the drying operation, the grain is placed slightly outside the central portion of the front machine wall on the front side,
Each viewing window of a predetermined size is provided at predetermined intervals in the up-down direction, and a predetermined amount of grain is loaded into the storage chamber while visually detecting the amount of grain loaded into the storage chamber through each of the viewing windows. To do. At the time of this stake-in work, the stake-in hopper position for staking in the grain is, for example, a model that is on the side of the machine body, and the worker who stakes in the grain machine must move to the front side of the machine body. , It was sometimes impossible to visually detect the amount of grain stuck into the storage chamber through the viewing window, but even if the machine has the pull-in hopper at any of the front side position and the side position of the machine body. It is intended to enable the operator to visually detect the amount of grains to be loaded into the storage chamber through the viewing window, regardless of the position of the operator who works to feed the grains.

[0004]

SUMMARY OF THE INVENTION The present invention is to transfer grains from the upper grain storage chamber 7 formed by the front / rear and left / right machine walls 4a, 4b, 4c, 4d to the lower grain drying chamber 8. While drying and circulating the particles while letting them flow out, the drying hot air from the burner 3 is ventilated to the drying chamber 8 for drying, and the front, rear, left, and
The four corners of the storage chamber 7 formed by the right machine walls 4a, 4b, 4c, 4d are notched diagonally 7a to form a vertical surface 7b in the up-down direction, and the vertical surface 7b is extended to the inside of the storage chamber 7. A stuck grain detecting device for a grain dryer is characterized in that a plurality of viewing windows 7c of a predetermined size for visually observing the amount of the incorporated grains are provided at predetermined intervals in the vertical direction.

[0005]

[Operation and effect of the invention] Before / after and left of the grain dryer
The grains stored in the upper grain storage chamber 7 formed by the right machine walls 4a, 4b, 4c, 4d are fed out from this storage chamber 7 to the lower grain drying chamber 8 and circulated, When the dry hot air from the burner 3 passes through the drying chamber 8, the dry hot air is exposed to the dry hot air and dried, and when the moisture content of the grain being dried is equal to or less than the target finish moisture, the drying is considered to be completed. The dryer is automatically stopped to stop the grain drying.

In the grain loading operation in the first stage of this drying operation, the four corners of the storage chamber 7 formed by the front, rear, left and right machine walls 4a, 4b, 4c, 4d are notched obliquely when viewed from a plane. Gi 7a
