Description

TECHNICAL FIELD The present invention relates to a fertilizer replenisher for replenishing a fertilizer tank of a fertilizer application apparatus in a field with liquid fertilizer or granular fertilizer from outside the field.

(B) Conventional Technology Conventionally, fertilizer fertilizers are applied while traveling in the field, and when replenishing fertilizer, the fertilizer in a bag is transferred to a container such as a bucket and then replenished to a fertilizer tank in the field.

(C) Problems to be solved by the invention When fertilizer is replenished, the fertilizer in a bag is temporarily transferred to a transport container such as a bucket, and then the container is carried in the field and lifted to replenish the fertilizer tank. Therefore, the heavy fertilizer had to be transferred twice, and this work was extremely heavy work, and it was troublesome and the replenishment time was long, resulting in a decrease in work efficiency. In particular, it was a harsh work in a plowed field where the working conditions were bad.

Also, when the fertilizer was transferred to a container or replenished in the fertilizer tank, it was spilled and wasted.

Furthermore, in order to eliminate the above-mentioned problems, bag fertilizer,
Once it was put into the fertilizer storage tank and supplied to the fertilizer tank of the fertilizer applicator with a pump and a hose, precipitation occurred during storage, and the fertilizer concentration when it was pressed into the fertilizer tank changed.

Furthermore, when the fertilization work is finished, the work of extracting the fertilizer remaining in the fertilizer tank is troublesome and the fertilizer may be spilled.

(D) Means for Solving Problems The present invention relates to a fertilizer storage tank, a pressure feeding device for feeding fertilizer in the fertilizer storage tank, and a prime mover for driving the pressure feeding device.
A delivery hose for supplying the fertilizer pumped by the pumping device to the fertilizer tank of the fertilizer applying device is mounted on the machine base, and the suction port and the discharge port of the pumping device are connected by separate flow paths, and those flow paths and the above In the flow path leading to the delivery hose, the pumping mode in which the fertilizer inhaled from the fertilizer storage tank is discharged back into the fertilizer storage tank to be agitated, the pumping mode in which the fertilizer inhaled from the fertilizer storage tank is delivered to the delivery hose, and the fertilizer application The above-mentioned problems have been solved by interposing a switching device for switching between a fertilizer in the fertilizer tank of the apparatus and a pumping mode in which the fertilizer is sucked through the delivery hose and discharged so as to be returned to the fertilizer storage tank.

(E) Action Fertilizer is taken out of the bag and stored in the fertilizer storage tank of the fertilizer replenisher located on the farm roads around the field, and when the fertilizer tank of the fertilizer application runs out of fertilizer during operation When the fertilizer is fed to the delivery hose under pressure, the delivery device is driven in this state and the delivery hose is inserted into the fertilizer tank supply port of the fertilizer application. The fertilizer in the fertilizer storage tank of the fertilizer replenisher is pumped and filled into the fertilizer tank of the fertilizer applicator, and when it is full, the pumping is stopped and the fertilizer application is restarted.

Further, when the storage time of the fertilizer stored in the fertilizer storage tank becomes long, the fertilizer in the fertilizer storage tank circulates through the pressure delivery device when the pressure delivery device is driven while the switching device is switched back to the pressure delivery mode. , So that the concentration becomes almost constant because it is stirred, and then the fertilizer is supplied to the fertilizer tank.

Further, when fertilizer is left in the fertilizer tank at the end of the fertilizer application, when the switching device is switched back to the pressure feeding mode and the pressure feeding device is driven, the fertilizer in the fertilizer tank is removed via the feeding hose. It can be returned to the fertilizer storage tank.
