Description

[Detailed explanation of the invention] This invention has multiple discharge jets in the left and right directions of the machine so that it can supply chemicals such as fertilizers and herbicides for seedling cultivation at the same time as seedling planting. This invention relates to a rice transplanter with a fertilization device, which has a main tank connected to a fertilizer tank equipped with an outlet and which continuously or almost continuously supplies fertilizer or chemicals to the fertilizer tank.

In the rice transplanter mentioned above, the main tank and fertilizer tank are generally connected through a single pipe, etc.
Fertilizer from the main tank accumulates near the supply port to the fertilizer tank, and the amount of fertilizer supplied to the discharge port located away from the supply port is small.For example, the main tank side becomes empty, and the fertilizer in the fertilizer tank When the amount becomes low, the supply of fertilizer is stopped at the discharge port far from the supply port earlier than other discharge ports, and the fertilizer in the fertilizer tank is evenly supplied from all the discharge ports until the end. There was a drawback that I couldn't do it.

In view of the above points, the present invention aims to level out the fertilizer in the fertilizer tank so that the entire amount can be uniformly supplied from all discharge ports, and to simplify the configuration for this purpose. With the goal.

In order to achieve the above object, the present invention provides the above-mentioned rice transplanter with a fertilization device, in which a leveling tool is attached to the fertilizer tank, and the leveling tool and the operating part of the seedling planting device are interlocked and connected. It is characterized by certain things.

In other words, the fertilizer supplied from the main tank is successively leveled by a leveling tool driven by the actuating part of the seedling planting device, such as the seedling stand or the transmission shaft of the planting mechanism, until the main tank is emptied. Even in a worn-out state, the same amount of fertilizer is stored above each discharge port.

Therefore, if the fertilizer supply stops at all outlets almost simultaneously, and the fertilizer supply from some outlets is stopped early even though fertilizer remains in the fertilizer tank, This enabled us to avoid this problem and make it possible to supply almost the entire amount of fertilizer in the fertilizer tank. Moreover, since the leveling tool is driven using the actuating section of the seedling planting device, the drive structure can be simplified compared to, for example, a case where an electric motor is attached.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings.

A running vehicle body has a pair of left and right front wheels 1, 1 and rear wheels 2, 2 mounted on an axis, an engine 3 is mounted in the front part, and a steering wheel 4 and a driver's seat 5 are provided behind it.

8, the fertilizer tank 19 is narrow and long in the left and right direction of the aircraft.
At the same time, five discharge ports 20 are provided at the bottom of the fertilizer tank 19 at predetermined intervals in the left-right direction of the machine, and the floats 14 are placed slightly in the left-right direction of the machine from the planned trajectory for planting each seedling. A soil supply section 21 for fertilizer is attached to a location offset to one side, and the soil supply section 21 and the discharge port 20 are connected to each other via a first supply pipe 22, and the discharge port 20 ...Each is equipped with a rotary valve 23 for quantitative supply.

The main tank 17 and the fertilizer tank 19 are connected to each other at approximately the center in the left-right direction of the machine body through a single flexible second supply pipe 24 in a state that allows the seedling planting device 8 to be driven up and down. With the above configuration, fertilizer is supplied from the main tank 17 to the vicinity of the planted seedlings via the second supply pipe 24, the fertilizer tank 19, the discharge port 20..., the first supply pipe 22... and the ground supply section 21. The fertilization equipment is configured in such a way that

The communication opening area of the connecting portion between the main tank 17 and the second supply pipe 24 is configured to be smaller than the cross-sectional area of the second supply pipe 24, and the second supply pipe 24 is not filled with fertilizer as much as possible. , from main tank 17 to fertilizer tank 1
The structure is such that fertilizer is continuously or almost continuously supplied to the container 9.

A mounting shaft 25 is provided in the upper space of the fertilizer tank 19 so as to be slidable in the left-right direction of the machine, and a plate-shaped leveling tool 26 is mounted on the mounting shaft 25 so that the mounting shaft 25 protrudes from the fertilizer tank 19. and one end side,
It is connected to the seedling stand 11 via a connecting rod 27, and as the seedling stand 11 moves laterally, the leveling tool 26 is driven and moved to level the fertilizer in the fertilizer tank 19. It is configured.

The main tank 17 is attached to the support frame 16 so as to be rotatable and fixed around the left-right axis Q of the aircraft, and is configured to be changed between a horizontal position along the sunshade 15 and a vertically hanging position. In addition, a suction device 28 such as a fan or a vacuum pump is attached to the main tank 17, and the second supply pipe 24 is connected to the fertilizer tank 19 in a detachable manner, and as shown in FIG. By separating the supply pipe 24 from the fertilizer tank 19 and inserting it into the fertilizer bag 29, placing the fertilizer tank 19 in a hanging position, and driving the suction device 28 in this state, the tank 1 is removed.
The structure is such that the inside of the main tank 17 can be effectively sucked and supplied with negative pressure in the main tank 17.

FIG. 5 shows another embodiment, in which leveling tools 26 are mounted on the mounting shaft 25 at approximately the center of the seedling stand 11 in the left-right direction of the machine body, and on each side thereof, and the leveling tools 26, 26 on both sides are Auxiliary leveling tool 2 is installed at the bottom end so that it escapes to the outside of the machine only when moving inward.
