Conventionally, Japanese Unexamined Patent Publication No. 5-27 is disclosed.
As shown in Japanese Patent No. 6818, a planting section is provided on the rear side of the traveling vehicle, an air tank, a fertilizer hopper, a fertilizer feeding case and the like are mounted on the rear upper surface of the traveling vehicle, and a fan case of a blower is provided on one side of the air tank. There is a technique in which the fertilizer is fed from a fertilizer feeding case to a planting section via a transfer hose by air blowing from an air tank when the fertilizer is connected to the plant. However, since the stay is provided and connected between the end face of the air tank and the end face of the exhaust port of the fan case, it is necessary to form the fan case with high rigidity, and it is easy to reduce the manufacturing cost of the fan case and improve the mounting strength. I can't do it. Also, since an electric fan motor is provided on the back of the fan case and the intake port is opened forward on the front of the fan case,
By storing the fan case in front of the air tank, the electric fan motor protrudes outside the fan case, which makes it difficult to reduce the lateral width during transportation and prevent damage to the fulcrum shaft due to vibration, etc. Alternatively, there is a problem that car wash water easily enters the fan case from the air inlet, and fertilizer easily absorbs moisture.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a planting portion on the rear side of a traveling vehicle, and attaches an air tank, a fertilizer hopper, a fertilizer feeding case, and the like to an upper surface of a rear portion of the traveling vehicle. In a rice transplanter in which a fan case of a blower is connected to a side portion and fertilizer from a fertilizer feeding case is sent out to a planting portion via a transfer hose by blowing air from an air tank, a stay having one end connected to a fulcrum shaft in front of an air tank. The other end of the fan case is extended and fixed to the front of the fan case, an electric fan motor for driving the blower fan inside the fan case is provided on the front of the fan case, and the intake case is extended downward on the back of the fan case. The fan case has a cover that closes the upper part of the intake port at the lower end of the intake case, and the fan case is stored in front of the air tank. The intake case is located outside the fan case, and the stay is fixed by extending it to the front of the fan case. The fan case can be easily formed, the manufacturing cost of the fan case can be reduced, the mounting strength can be easily improved, and the intake case is provided downward on the back of the fan case. It can easily prevent rainwater or car wash water from entering by blocking the front and rear, and because the upper part of the intake port is closed by the cover, it can easily prevent intrusion of water droplets scattered by wind etc.
Since the clogging accident of fertilizer or fertilizer dust that easily absorbs moisture can be easily eliminated and the intake case is located outside the fan case stored in front of the air tank, the left and right width when storing the fan case can be formed compactly, It is possible to easily reduce the left and right width at the time of transportation mounted on a truck bed or the like, and to easily protect the electric fan motor and the like at the time of transportation and reduce vibration.
