Abstract

PURPOSE:To prevent damage to a chain transmission device through reversing drive of a chain transmission device, by a method wherein transmission of the chain transmission device of a delivery valve to deliver storage cereals can be started only after transmission of a cereals raising machine or an exhaust fan. CONSTITUTION:Transmission of a chain transmission device 3 to rotationally drive a delivery valve 2 for delivery and flow-down of stored cereals in a drying chamber 1 causes rotational drive of the delivery valve 2 after rotational drive of a cereals powder raising machine or an exhaust fan 5 except the delivery valve 2. Thus, even when a motor to rotationally drive each part of a drier is a 3-phase motor and the motor is reversed due to wrong connection, reverse drive of the cereals raising machine or the exhaust fan 5 is detected before rotational drive of the delivery valve 2, and the connection of the motor can be corrected. Since the chain transmission device 3 to rotationally drive the delivery valve 2 is prevented from reversing, this constitution prevents damage to the chain transmission device 3.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a starting device for a grain dryer.

2. Description of the Related Art Conventionally, a dryer is started for each task of loading, drying, and discharging.Depending on the sequence of operation of the loading start switch, drying start switch, and discharge start switch, The transmission of the chain transmission device of the feeding valve that feeds out the stored grains,
Alternatively, it was an operating device equipped with a starter device that rotates and drives an exhaust fan or the like at the same time as transmission.

Problems to be Solved by the Invention When the assembly and installation of the dryer is completed, a power supply is connected to the dryer and a trial run is performed by operating the operating device according to the order of each work process. Operate the drying start switch to perform the drying process to start the dryer, and if this process is OK, operate the drying start switch to perform the next drying process to start the dryer and complete this drying process. If the work process is OK, the dryer is started by operating the discharge start switch for the next process of discharge work, and if the discharge work process is OK, the trial run for each work is completed.

During this test run, when I started the dryer by operating the drying start switch first, I realized that the dryer's motor was a three-phase motor and the wiring was incorrect. In this state, this three-phase motor rotates in the opposite direction, and during the drying process, all parts of the dryer simultaneously rotate in the opposite direction. When the transmission gear is driven in reverse rotation, the chain 7 becomes jammed, causing damage to the chain transmission.

Means for Solving the Problems The present invention provides transmission of the chain transmission El (3) of the feeding valve (2) for feeding out the grains stored in the drying chamber (1) by a mechanism other than the feeding valve (2). The starting device for the grain dryer is configured so that it can be started only after kJ of the grain raising machine (4) or the exhaust fan (5) is transmitted.

Effect of the Invention After the assembly and installation of the dryer is completed, the power is connected to the dryer and the operating device is operated to perform a trial run of the dryer. Even if you operate it first.

If the rotational drive of the grain raising alk (4) or the exhaust fan (5) is not transmitted before this operation, the feed valve (2) that feeds out the grain stored in the drying chamber (1) and flows down. A chain transmission system that rotates and drives m! (3) is not rotationally controlled by the starting device, so it is not possible to dry the grains, so the dryer operates the loading start switch that starts loading the grains into the dryer, and the dryer
(4) or after rotating the exhaust fan (5), when the drying start switch for drying is operated, the starting device controls the rotation of each part of the dryer to dry the grains. can be done.

Effects of the Invention According to the present invention, the transmission of the chain transmission device 1 (3) that rotationally drives the feed-out valve (2) that feeds out and flows down the stored grains in the drying chamber (1) is controlled by a lift other than the feed-out valve (2). The feed valve (2) cannot be rotated unless the grain machine (4) or the exhaust fan (5) is rotated, so the motor that rotationally drives each part of the dryer is a three-phase motor, and the wiring Even if it is wrong and this motor rotates in the opposite direction,
Before rotating the feeding valve (2), the grain raising machine (4)
, or noticed that the exhaust fan (5) was being driven to rotate in the opposite direction, and the wiring of this motor was properly corrected, thereby preventing the chain transmission (3) that rotates the delivery valve (2) from rotating in the opposite direction.
