Description

[Detailed description of the invention] Generally, paste-like liquid fertilizer is adjusted to a viscosity that allows it to flow through a hose and be applied into the soil.

The liquid fertilizer tank of the fertilizer applicator in conventional rice transplanters and other paddy field working machines was fixed to the machine frame, so when particles in the liquid fertilizer settled in the planting machine and the viscosity became high, the liquid fertilizer The tank becomes clogged,
To prevent this, the only way to prevent this is to shake the liquid fertilizer tank along with the aircraft, which is extremely difficult, and when the viscosity increases, if you do not drain the liquid fertilizer from the drain of the liquid fertilizer tank, it may become clogged and become unusable. There is.

The present invention aims to prevent the liquid fertilizer from becoming clogged by increasing the viscosity of the liquid fertilizer by swinging the liquid fertilizer tank up and down, thereby preventing the liquid fertilizer from clogging. In a paddy field work machine equipped with a tank, one end side of the liquid fertilizer tank is pivotally supported on the machine frame, and the other end side of the liquid fertilizer tank is linked to swing in conjunction with the swinging of a swinging member provided on the machine body. It is characterized by being connected.

The embodiment shown in the drawings will be explained below.1
is equipped with engine 2 at the front and planting device 3 at the rear.
The swing transmission case 6 has its front portion attached to the output shafts 5, 5 on both sides of the intermediate portion, and wheels 7 are pivotally supported at the rear of the swing transmission case 6. The arms 8, 8 installed upright are connected to both ends of the horizontal rod 10 by links 9, 9, respectively, and the rod of a hydraulic cylinder 11 mounted on the body 1 is connected to the intermediate portion of the horizontal rod 10.

The front part of the center float 12 provided at the bottom of the fuselage 1 is connected by a rod 13a to one end of a link 13 whose intermediate part is pivotally supported, and the other end of the link 13 is used to switch the hydraulic cylinder 11 via a wire 13b. Since it is connected to the valve, wheel 7
When the front part of the center float 12 moves up and down while rolling along the unevenness of the tiller, the switching valve is switched and the hydraulic cylinder 11 is operated, and when the wheel 7 rides on the protrusion, the swing transmission case 6 and wheels 7 are raised relative to the fuselage 1 and lowered when entering the recess.

Liquid fertilizer tank 1 contains paste fertilizer.
The front part of the liquid fertilizer tank 14 is pivotally supported by a column 15 set up on the body so that it can be tilted up and down, and the rear part of the liquid fertilizer tank 14 is swung up and down by a connecting rod 16 together with the wheels rolling on the uneven plowing platform. Since it is interlocked and connected to the rear upper surface of one of the swing transmission cases 6, when the swing transmission case 6 moves up and down as described above, the liquid fertilizer tank 14 moves to the first position about the pivot shaft 17.
It repeats the process of rising as shown in the figure and descending as shown in Fig. 2, during which time the stored liquid fertilizer flows up and down and back and forth as if being stirred, causing the particles in the liquid fertilizer to settle. Prevent viscosity from increasing.

Further, the suction port of the pump 4 is connected to the liquid fertilizer tank 14.
The discharge port of the pump 4 is connected to the discharge port at the lowest part of the bottom of the pump 4 by a bellows-shaped hose 18, and the discharge port of the pump 4 is connected to the fertilization pipe 21 by a hose 20 having an outflow confirmation meter 19 in the middle. The liquid fertilizer in the liquid fertilizer tank 14 is transferred to the fertilization pipe 21 by the pressure-feeding action of
Fertilizer is applied to muddy soil.

As described above, the present invention is a paddy field working machine that is equipped with a liquid fertilizer application device and a liquid fertilizer tank, in which one end of the liquid fertilizer tank is pivoted to the machine frame, and the other end of the liquid fertilizer tank is The liquid fertilizer in the liquid fertilizer tank 14 repeatedly moves back and forth and up and down because the liquid fertilizer in the liquid fertilizer tank 14 is moved back and forth and up and down repeatedly, and particles in the liquid fertilizer settle during work. The viscosity of the fertilizer increases, which can cause clogging, and the need to shake the machine to prevent clogging, or to remove liquid fertilizer that has lost its high viscosity, allowing work to be carried out with peace of mind and with high efficiency.
