Description

[Detailed Description of the Invention] The present invention relates to a fertilization device for an agricultural working machine that is capable of fertilizing the soil at the same time as the working of the agricultural working machine.

In order to maintain the balance of the machine, the fertilizer storage tank in the fertilization device of agricultural machinery is divided into two, on the left and right sides of the center of the machine.
The fertilizer supply paths of these two tanks are merged and connected to a fertilization pump, and the fertilizer is discharged from the fertilization pump to a fertilization nozzle. However, when filling each tank with paste-like fertilizer, it is generally necessary to transfer a commercially-bagged bag of fertilizer to a bucket or the like and stir it before adding it. Therefore, due to the difference in the degree of stirring, there may be a slight difference in viscosity between the paste fertilizer supplied to the left and right tanks, or the state of precipitation may vary between the left and right tanks. Therefore, of the left and right tanks, the side filled with paste-like fertilizer with low viscosity will consume the fertilizer faster than the other side, and in this case, air may be trapped in the fertilizer supply pipe. There is a problem that the paste fertilizer becomes difficult to flow because it mixes and causes vapor lock.

Vapor lock makes it difficult for fertilizer to flow, resulting in variations in fertilization conditions. For example, in a multi-row rice transplanter that has one fertilization pump for each fertilization nozzle in each row, the paste fertilizer may be unevenly distributed to each fertilization pump. This causes the problem of uneven seedling growth.

The purpose of this invention is to solve the above-mentioned problems with conventional equipment and provide separate tanks for storing fertilizer on the left and right sides of the aircraft. It is an object of the present invention to provide a fertilization device for an agricultural working machine, which can uniformly apply fertilizer at all times without introducing air after the fertilization pump.

The fertilization device for the agricultural machine of the present invention that achieves the above purpose is provided with main tanks for storing fertilizer on the left and right sides of the machine body, and the fertilizer in both main tanks is supplied to the fertilization nozzle via a fertilization pump. The apparatus is characterized in that a sub-tank connected to the fertilizer supply paths of both tanks is provided at a position lower than the bottom surfaces of both tanks, and this sub-tank is connected to a fertilization pump.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to embodiments shown in the drawings.

The figure shows a riding-type rice transplanter for five-row planting equipped with a fertilization device according to the present invention, in which a front wheel 2 and a rear wheel 3 are provided at the front and rear of the machine body 1, respectively. Further, a planting device 4 is connected to the rear of the body 1 via a lower link 5 and an upper link 6. 7 is a seedling stand provided on the top of the planting device 4, and 8 is a float supported by the planting device 4.

Auxiliary seedling stands 10 are fixed on both sides of the driver's seat 9 on the machine body 1 and on both outer sides of the rear wheels 3, which are approximately at the center of gravity of the machine.
Main tanks 12 for storing paste fertilizer are fixed to the lower ends of the frames 11 on both sides of the frame 11 to which the machine 0 is fixed, to balance the machine body. Lower frame 1 of the aircraft 1 located below the driver's seat 9
Inside a is a sub-tank 1 for storing paste fertilizer.
3, a fertilization pump 14 is also provided. The sub-tank 13 is fixed at a position lower than the horizontal line L connecting the bottoms of the main tanks 12, and pipes 15, 15, which are fertilizer supply paths for the two main tanks 12, 12, are connected to the sub-tank 13. . On the other hand, five fertilization pumps 14 are provided corresponding to the number of planting rows, and these five fertilization pumps 14 are
Installed in the fuselage 1 for power extraction of the planting device 4
It is designed to be driven by receiving power from the PTO shaft 16. The sub-tank 13 and each fertilizer pump 14 are connected by pipes 17, respectively. Further, from each of the five fertilizer pumps 14, a pipe 18 for supplying fertilizer extends rearward and is connected to a fertilizer nozzle 19, respectively.

The five fertilizing nozzles 19 are arranged and fixed at predetermined intervals to a horizontal bar 20 fixed to the lower link 5 so as to extend in the lateral direction. This horizontal bar 20 has a pin 21 located at the center of the fuselage.
The pin 21 is pivoted to the fulcrum and can be rolled left and right. On the other hand, the planting section frame 22 of the planting device 4 is pivotally supported by a pin 23 provided at the center of the body, and is able to freely roll left and right using the pin 23 as a fulcrum. Furthermore, the planting section frame 22 and the horizontal bar 20 are connected to the support frame 2.
4 and are connected and fixed to each other so that the rolling of both is synchronized. in this way,
Fertilizing nozzle 19 is not fixed to float 8,
By being fixed to the horizontal bar 20 fixed to the lower link 5, not only does piping to the planting device side become unnecessary, but also the float 8
Since the fertilizing nozzle 19 does not exert any resistance on the rice, the planting device can roll smoothly from side to side, improving its ability to follow the rice field surface, and its planting performance is not hindered. Furthermore, since no complicated structural parts such as piping are added to the planting device, its maintainability is not hindered. Furthermore, when the planting device 4 is restored during turning, etc., the discharge end of the fertilizing nozzle 19 is tilted upward as the lower link 5 rises, so that the paste fertilizer flows out from the nozzle end and leaves the seedlings. It also prevents things that could cause harm to people.

Now, in the fertilization device in the rice transplanter mentioned above,
Main tanks 1 on the left and right sides of the aircraft to maintain balance.
Since the two main tanks 2 and 12 are installed separately, the fertilizer in one of the main tanks may decrease faster due to the viscosity variation of the left and right paste fertilizers, but the sub tank 13 is located lower than the main tank 12.
Since the fertilizer from both main tanks is combined into this sub tank 13,
Air is not mixed into the fertilization pump 14 side. That is, even if the fertilizer in one main tank is consumed quickly, the sub-tank 13 is always kept full because the fertilizer is replenished from the other main tank, which prevents air from entering the fertilization pump 14. Instead, each fertilizer pump always discharges a fixed amount of paste-like fertilizer. In addition, in the case of a multi-row rice transplanter, the complicated configuration of connecting the inlet pipe of each fertilization pump to both main tanks is eliminated, making maintenance easier and reducing breakdowns. It will be done.

As mentioned above, the fertilizer application device for the agricultural machine of the present invention has main tanks for storing fertilizer on the left and right sides of the machine body, and the fertilizer in both main tanks is supplied to the fertilizer nozzle via the fertilizer pump. In this case, a sub-tank connected to the fertilizer supply path of both tanks was provided at a lower position than the bottom of both tanks, and this sub-tank was connected to the fertilizer pump, so that the fertilizer could be supplied to either the left or right main tank. Even if it is consumed quickly,
The inside of the sub-tank connected to both main tanks is always kept full, and air is not mixed into the fertilization pump side, making it possible to always apply fertilizer uniformly.
