Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an air blowing device to the tiller to restore the aeration and drainage properties of the hardened tiller around the roots of crops such as fruit trees, and to improve the soil W. , and blows out pressurized air from the bottom to expand and soften the tiller, and furthermore, from this air blower, 111!
This invention relates to a soil improvement device for injecting powdered soil improvement agents such as fertilizer and lime into the tiller.

In conventional soil improvement equipment, the soil conditioner in the hopper is injected into the ground after the pressurized air is emptied and blown into the ground. When injecting through the auxiliary tank, the soil conditioner tends to adhere to the inner wall of this auxiliary tank, and the soil conditioner that adheres in this way worsens the flow, making it difficult to smoothly inject the air into the air blower. The problem is that it won't happen.

Therefore, in this invention, the hopper (1) is used while deeply cultivating the soil.
In a soil improving device configured to blow a soil improving agent stored in a hopper into the ground using pressurized air, an auxiliary tank is provided at the bottom of the hopper to store a soil improving agent equivalent to one injection, A soil conditioner supplying device is provided with a pressurized air injection port in the upper part of the auxiliary tank for blowing off the soil conditioner adhering to the inner circumferential wall of the auxiliary tank. The soil conditioner adhering to the inner circumferential wall of the auxiliary tank is blown off each time it is ejected, and the soil conditioner is prevented from adhering to the inner circumferential wall of the auxiliary tank, so that the injection operation can be carried out smoothly.

And - to explain an actual example, in the figure (1) is a hopper that stores the soil conditioner, and the auxiliary tank (
2) are connected in series through the shutter (3), and the shutter (3)
is the piston (5) of cylinder r4) (4) installed on the left and right.
(5) The Q slides in and out, and communicates between the hopper (1) and the auxiliary tank (2) through the opening (6) provided in the shutter (3). The hopper (1) is equipped with an agitator (8) that rotates by a motor (force) installed at the top of the hopper (1), and a stirrer (8) that rotates by a motor (force) is installed at the top of the hopper (1). A jet nozzle (9) for pressurized air is provided which is bent along the line and further projects diagonally downward at the tip thereof, and pressurized air is injected from this nozzle nozzle (9) to the auxiliary tank (2).
Pressurized air is blown in a spiral along the inner circumferential wall of the auxiliary tank (2) to wipe away the soil conditioner Q agent that adheres to the inner circumferential wall, thereby preventing the soil conditioner from adhering in layers to the inner circumferential wall of the auxiliary tank (2). do. or,
In the lower part of the auxiliary tank (2), a pressure air inlet 00) and a soil conditioner inlet 111) are provided facing each other on the same axis with a predetermined interval apart. The upper shutter (3) is connected to the hopper and auxiliary tank (as shown in the plan view of Fig. 6).

(Through snoring, the lower link (1ω (10) is raised and lowered, and the marking mechanism (I) is configured so that the device frame (F') always moves up and down in the same posture. Then, as shown in the front view in Fig. 3, the air tank C21 is installed on top of the driving mechanism (K), which has the air blowing body Q1 at the bottom, and the air tank C21 is installed on the left and right sides of the air tank (23).

511251, so that the ash tilling mechanism (I) can move up and down in a straight line, the tilling mechanism (I) is attached to the equipment frame (1) using a guide mechanism consisting of, for example, the above-mentioned vertical rail (2). (S) Supported by Vc.

As shown in the front view in Fig. 3 and in the side view in Fig. 4, there are passages (1) in three directions in the upper part of the air blowing body Cυ.
The valve body (p) of the switching valve (P) having → (-) is rotatably fitted, and the force piston ( 28a) and the protruding part of the valve body (p) are connected by a rod (', 3ji), and when the operating lever 1'' (■) installed near the driver's seat is operated, the valve (not shown) opens.

The upper passage (21c) and the lower 110,000 passage (21a) of the air blowing body (21) communicate with each other at the passage (→), and the passage (21d) connects to the valve body (p) as shown in the N-th passage. passage (21)

Next, if you release your hand from this operating lever (34) to close the air jet valve and then operate the other operating lever (Liu), pressurized air will be supplied to the switching cylinder r2 (to) by a valve not shown. Piston (2FA) IJ - protrudes, valve body (p) rotates and air blowing body (21) 6 auxiliary tanks

From @ through the passageway (10a), water flows out into the pond, and
A certain amount of soil conditioner stored in the auxiliary tank (2) in advance is pumped through the hose C'l+3 by this jet of pressurized air.
The soil improver is sucked from the passageway (21d) into the passageway (21a), and is injected into the tiller from the blowout hole (21b). Once the predetermined amount of pressurized air and soil improver have been ejected into the ground, the equipment frame (1) is lifted again and moved to the next work area.

In this invention, when injecting the above-mentioned soil conditioner into the tiller, pressurized air is simultaneously ejected from the jet nozzle (9) provided above the auxiliary tank (2).
2) Pressurized air is blown in a spiral along the inner peripheral wall of the tank (2) to wipe off the soil conditioner adhering to the inner wall and cause it to fall, and the soil conditioner is injected into the tiller from the passage below the auxiliary tank (2). It is also poured into the tiller.

The soil conditioner supply device according to the present invention is provided with an auxiliary tank having a capacity equivalent to one injection at the bottom of the hopper, and pressurized air is sent spirally downward onto the inner peripheral wall from the injection nozzle provided at the top of the auxiliary tank. By constantly blowing off the soil conditioner adhering to the auxiliary tank, the soil improver no longer adheres to the inner wall, and as a result, the soil conditioner can be smoothly injected into the soil. It is.
