JP 2010-268712 A

  The above-mentioned medicine spraying device equipped with the spraying amount control device or the medicine spraying device that manually operates the spraying operation is a spray valve opening / closing operation, a main cock opening / closing operation for switching the chemical solution to a spraying state or a circulation state, and a boom opening / closing operation. Various drive units that perform the above operation electrically are provided, and an operation input unit that operates the operation of the drive unit is provided around the driver's seat of the traveling machine body (for example, in the driving cabin).

  In such a medicine spraying device, the operator can perform normal spraying work without an auxiliary worker by operating the operation switch of the operation input unit while driving the traveling machine body in the driver's seat. However, in the inspection / preparation and maintenance work, etc., where the drug spraying device mounted on the traveling machine is directly handled, the operation input section around the driver's seat must be set every time the operation of the drug spraying device is checked and the chemical solution is circulated. In order to operate, it is necessary to move from the rear part of the traveling machine body to the vicinity of the driver's seat, and there is a problem that good workability cannot be obtained.

  In particular, when the relationship between spraying pressure and spraying flow rate is not set and there is an abnormality in the spraying operation, it is necessary to stop the traveling machine and check for nozzle abnormalities even in the middle of the field. However, in such a case, it is necessary for the operator to get out of the driver's seat and check the clogging of the nozzle provided in the boom portion of the medicine spraying device mounted on the rear part of the traveling machine body. At this time, if an attempt is made to check the spraying state after removing foreign substances clogged in the nozzle, the operator once returns to the vicinity of the driver's seat and operates the operation input unit. If the normal spraying state cannot be confirmed, the inspection of the nozzle located at the rear of the traveling machine body and the operation of the operation input unit that is performed around the driver's seat are repeated, and there is a problem that requires a lot of labor to avoid the abnormality. there were.

  Also, in the preparatory work before spraying work, for example, in the preparation work of the chemical solution to be put into the tank, after the chemical solution is put into the tank containing water, the pressure of the mixed liquid in the tank is adjusted from the main cock. Circulating agitation is performed by returning to the tank via the circulation path. If such a chemical solution is added and circulated and stirred by one worker, the pump drive and pressure adjustment operations after the chemical solution is supplied to the tank must be performed by the operator leaving the tank and moving around the driver's seat. Thus, there is a problem that it is impossible to perform an efficient work even in such a preparatory work.

  In order to solve such a problem, it is only necessary to provide an operation input unit around both the driver's seat and around the medicine spraying device. However, if the operation input unit is provided at a plurality of locations, the signal wiring becomes complicated and a failure or malfunction occurs. It is easy to cause. This invention makes it an example of a subject to cope with such a problem.
