Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a grain stored in a grain storage chamber of a grain dryer is fed out from this storage chamber to the grain drying chamber and circulated while being circulated. As the drying air passes through the drying chamber, the grains flowing down in the drying chamber are exposed to the drying air and dried. Before this drying work, the dryer is installed in the work place.At the time of this installation work, it is necessary to install the grain raiser on the front side or the rear side of the machine due to the work place. The operating device having the starting means and the stopping means for starting and stopping the dryer is mounted on the front side of the machine body of the dryer, and thus, for example, the grain is loaded into the grain-raising machine. If the machine is equipped with a stake-in hopper, a malfunction occurs in the dryer during the stake-in operation in which the grains are put into the stake-in hopper and it is necessary to stop this dryer urgently. When this occurs, if this grain raising machine is installed on the front side of the machine body,
By performing the staking work on the front side of the machine body, by operating the stop means of the operation device mounted on the front side of the machine body,
This dryer can be stopped immediately.

When the grain raising machine is mounted on the rear side of the machine body, the operator performing the staking operation is mounted on the front side of the machine body by performing the staking operation on the rear side of the machine body. In order to operate the stop means of the operation device, the operator cannot move the operator to the front side of the main body and operate it, so that the dryer cannot be stopped immediately, and the dryer is damaged secondarily. There was something to do.

Further, in the case of a machine equipped with a stake-in hopper for squeezing grains on either the left or right side of the side wall of the dryer, when an emergency stop is performed in the same manner as described above, the operator must move to the side. It was necessary to move from the side to the front side of the main body, and the secondary damage to the dryer sometimes occurred.However, it was possible to immediately stop the dryer from either side, and this secondary This is intended to prevent physical damage.

[0005]

Therefore, according to the present invention, the grain is fed from the grain storage chamber 7 in the upper part to the grain drying chamber 8 in the lower part and allowed to flow down and conveyed to the upper part by the grain raising machine 25 to store the same. While being supplied to the chamber 7 and circulated, a drying device is provided for drying with a drying air, and an operating device 14 for operating a driving device is provided. The operating device 14 is provided with a starting device 33 for starting operation and a stopping device 34 for stopping operation. In the provided grain dryer, the entire length of the emergency stop harness 31 of the emergency stop means 32 for stopping the dryer other than the operation of the stop means 34 of the operating device 14 is set to a half circumference of the machine body of the dryer. The operation stop device for the grain dryer is characterized by being provided.

Further, an operation stop of the grain dryer is characterized in that an emergency stop means 32 for stopping and operating the dryer other than the operation of the stop means 34 of the operation device 14 is provided so as to be suspended from a ceiling portion of the dryer. The device configuration. Alternatively, the operating device 14
The operation stop device for a grain dryer is characterized in that mounting connectors 45 for mounting the emergency stop means 32 for stopping the dryer other than the operation of the stopping means 34 are provided at the four corners of the dryer body. And

[0007]

The function and effect of the invention: The grains stored in the grain storage chamber 7 of the grain dryer are fed out from the storage chamber 7 to the grain drying chamber 8 and flowed down, and then moved upward by the grain raising machine 25. The drying air passes through the drying chamber 8 while being conveyed, supplied into the storage chamber 7 and circulated, so that the grains flowing down in the drying chamber 8 are exposed to the drying air and dried. To be done.

The dryer is installed in the work place before the above-mentioned drying work. At the time of this installation work, the grain-raising machine 25 is attached to the front side or the rear side of the machine body due to the relation of the work place. The operating device 14 having the starting means 33 and the stopping means 34 for starting and stopping the dryer may be mounted on the front side of the machine body of the dryer. When a trouble occurs in the dryer during the stake-in operation in which the grains are put into the stake and the sewage is put into the sack 25, it is necessary to stop the dryer urgently. When mounted on the front side, the operator performing the staking operation operates the stopping means 34 of the operation device 14 mounted on the front side of the machine by performing the staking operation on the front side of the machine body. Stop this dryer immediately.

[0009] When the grain raising machine 25 is mounted on the rear side of the machine body, the operator performing the stake-in operation is performing the stake-in work on the rear side of the machine body, so that when the dryer is installed. To
The emergency stop means 32 attached to the emergency stop harness 31 having a half circumference of the machine is previously attached to the rear side of the machine, and when it is necessary to stop the dryer urgently, the emergency stop means 32 is installed on the rear side of the machine. By operating the mounted emergency stop means 32, the dryer is immediately stopped.

When the dryer is installed near the stake point, the stake of the grain in the dryer is a machine which carries out the stake operation from the side wall of the machine. The emergency stop means 32 attached to the length of the emergency stop harness 31 is attached, and when it is necessary to stop the dryer urgently, the emergency stop means 32 attached to the side of the machine is installed. Operate to stop this dryer immediately.

In the case of a machine provided with the emergency stop means 32 suspended from the ceiling of the dryer, the emergency stop means 32 is suspended to a place where the work is carried out in advance when the dryer is installed. When it is necessary to stop the dryer urgently in a state of emergency, the emergency stop means 32 provided near the stake-in work is operated to immediately stop the dryer.

In the case of a machine provided with an attachment connector 45 for attaching the emergency stop means 32 to the dryer, when the dryer is installed, the attachment connector 45 that is closest to the place where the stake-in work is performed in advance. When it is necessary to attach the emergency stop means 32 to an emergency stop of the dryer, the emergency stop means 32 provided in the vicinity of the stake-in work is operated to immediately stop the dryer.

According to the above, even when the staking operation is performed on the front or rear side or the side of the machine body, either the stop means 34 or the emergency stop means 32 of the operating device 14 is operated. As a result, the dryer can be stopped immediately, and thus, the delay of the stop operation of the dryer can be prevented and the secondary damage of the dryer can be prevented.
