[Prior Art] Generally, paddy field working machines such as rice transplanters are known to be provided with a side-row fertilizer applying apparatus for fertilizing fertilizer for initial growth along a planting row. By the way, in order to achieve smooth growth of seedlings, it is necessary to further apply fertilizer to the deep layer of the field. Therefore, conventionally, after performing lateral row fertilization, fertilizer for additional fertilizer is separately applied to the deep layer. For this reason, there is a drawback in that a deep-layer fertilizer application must be prepared separately, and labor required for side-line fertilization and deep-layer fertilization is required.

[Problems to be solved by the present invention]

The present invention was devised to eliminate the above-mentioned drawbacks, and it is possible to perform deep fertilization for side fertilization at the same time as side fertilization by using a traveling machine equipped with a conventional lateral fertilizer application device. It is an object of the present invention to provide a fertilizer application device capable of saving labor in fertilizer application and promoting the growth of seedlings.

In order to solve the above-mentioned problems, the technical means taken by the present invention is to provide a deep-layer fertilizer on the inside of the traveling wheel, behind the side-row fertilizer that is composed of the fertilizer pump and the transmission provided on the traveling machine body. The rotary shaft, which is located below the seat and is provided in series, is projected from the transmission of the side-row fertilizer application and the input shaft provided in the transmission of the deep-layer fertilizer application are connected through an interlocking mechanism. It is characterized by that.

[Function of device]

Therefore, according to the present invention, as the traveling machine body travels, the lateral strip fertilizer and the deep layer fertilizer are provided along the planting strip by the side strip fertilizer application device provided on the traveling machine body and the deep layer fertilizer application device provided behind it. Fertilization can be performed simultaneously. Then, the deep-layer fertilizing device located below the seat inside the traveling wheels can lower the center of gravity of the machine body and maintain good left-right balance. Moreover, in the deep-layer fertilizer application, it is only necessary to connect the input shaft of the transmission to the rotary shaft projecting from the transmission of the lateral-row fertilizer through the interlocking mechanism, so that a wasteful space inside the traveling wheel can be effectively utilized. It can be easily installed by using. Furthermore, since the transmission of the deep-layer fertilizer application and the transmission of the lateral strip fertilizer are connected in series, it is possible to shift the speeds of both transmissions by the same operation, and when adjusting the fertilizer application amount, etc. There is no fear of causing.

Reference numeral 23 denotes a deep-layer fertilizer application provided behind the side-row fertilizer application device 10. The deep-layer fertilizer application device 23 uses the space portion inside the rear wheel 3 below the seat 5 for the side-row fertilizer. It is arranged in series with the fertilizer application device 10. That is, as shown in FIG. 4, the deep transmission 24 is disposed between the side strip fertilizer application 10 under the seat 5 and the rear wheel 3, and the output of the deep transmission 24 is provided. The shaft 25 is communicatively coupled to an input shaft 27 of a deep pump 26 provided therebelow. The suction side of the deep pump 26 is connected to a deep tank 28 provided on the side of the seat 5 via a suction hose 29, and the discharge side is connected to a deep indicator 31 via a pipe 30. An indicator 31 is connected to the deep nozzle 32.

The input shaft 33 of the deep layer transmission 24 is connected to the side strip transmission.
By connecting the intermediate shaft 34 protruding from 11 through an interlocking mechanism 35 such as a belt, the deep layer transmission 24 is rotatably driven in conjunction with the lateral strip transmission 11. 36 is a lateral strip gearshift lever, 37 is a deep layer gearshift lever, and since both lateral gearshift levers 36, 37 have the lateral strip gearbox 11 and the deep layer gearbox 24 arranged in series, By operating in the same direction, it is possible to adjust the speed of each transmission.
