Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a mobile agricultural working machine that is suitable mainly for use in soil disinfection machines, fertilizer applicators, and the like.

(Prior Art) Various types of agricultural working machines have been proposed in the past.

However, each of these has its own advantages and disadvantages, and there are some practical problems.

In other words, due to slippage of the drive wheels against the soil, the injection interval of disinfectant or liquid fertilizer from the injection blade attached to the soil disinfection machine or fertilizer application machine fluctuates, causing uneven injection.
Further, there is a problem in that soil adheres to or blocks the injection hole of the injection blade, causing a failure in injection of the liquid agent.

(Purpose) Therefore, in view of the above-mentioned problems, the present invention provides a vibrating injection blade that swings back and forth, and utilizes the force acting on the injection blade from the soil to suitably perform liquid injection work. The aim is to provide an agricultural working machine that can

(Structure) The agricultural working machine according to the present invention is characterized by having a gear 2 that interlocks with a wheel 1 driven by a prime mover 7, so that one end of the gear 2 side moves downward only when the gear 2 is in a predetermined position. A crank 3 that is driven intermittently is swingably mounted, and the crank 3 is connected to the injection blade 16, which swings back and forth about a pivot point 13 with a gap, by an interlocking mechanism and a spring 16. The tank 4 and the injection blade 6 are connected to each other, and the tank 4 and the injection blade 6 are connected to each other via the plunger pump 5, and the plunger pump 5 is interlocked with the crank 3, and the tip of the injection blade 6 is made to protrude below the body 8. It is at the point where it becomes.

(Embodiments) Specific embodiments of this invention will be described below with reference to the drawings.

The main parts of the agricultural working machine according to this invention include an axle 1, a gear 2, a crank 3, a tank 4, a plunger pump 5, an injection blade 6, etc.

The axle 1 is driven by a prime mover 7, and a gear 2 is connected to the axle 1.
is directly attached.

The crank 3 is provided with a lug 10 at one end of which freely rolls with the gear 2 so that the crank end swings back and forth in the vertical direction about a pivot point 9 with respect to the machine frame 8. They are connected by an intermittent actuator 11.

The other end of the crank 3 is connected to a drive shaft 12 of a plunger pump 5 disposed at the front of the fuselage, and the plunger pump 5 communicates with a chemical tank 4 located approximately in the middle of the fuselage.

On the other hand, the injection blade 6 is interlocked and connected to the crank 3 via an auxiliary crank 14 in order to move back and forth about a pivot point 13 with respect to the machine frame 8.

The outflow port of the plunger pump 5 and the injection blade 6 are connected to each other by a flexible pipe, etc. as appropriate, and the crank 3 and the injection blade 6
The support shaft 15 and the support shaft 15 are biased by a spring 16 so as to be pulled together.

This invention has the above structure and operates as follows.

When the aircraft moves, the gear 2 rotates as the axle 1 rotates, and the roller 1 comes into contact with the gear 2 in a free-flowing manner.
0 causes the intermittent actuator 11 to be actuated downward, and therefore, naturally the actuator side 11 of the crank 3 is also moved downward.

This operation of the crank 3 simultaneously causes the other end of the crank 3 to move upward, driving the plunger shaft 12 upward and supplying the medicinal solution to the injection blade 6.

On the other hand, the movement of the crank 3 is transmitted to the sub-crank 14, which gives forward movement to the injection blade 6, and the chemical solution is injected from the injection blade 6 into the soil.

By the way, when the injection blade 6 is moved forward by the gear 2 and positioned at the top of its movement stroke, the engagement between the roller 10 and the gear 2 is released.

Since the injection blade 6 is held in the soil despite the movement of the machine body 8, the injection blade 6 receives a force acting in the opposite direction of movement, and the support shaft 15 moves backward.

Therefore, the intermittent actuator 11 moves upward, and after the body 8 has traveled a predetermined distance, it returns to its original position.

On the other hand, at this time, the plunger shaft is driven downward and the chemical solution is sucked from the tank 4 into the plunger pump 5.

Thereafter, the above operations will be repeated as the aircraft 8 advances.

Since the naori rank 3 and the injection blade 6 are connected through an interlocking mechanism (with play in the connecting part), when the intermittent actuator 11 of the crank 3 and the gear 2 are suddenly disengaged, ,
Due to the interaction between the momentum caused by the sudden loss of the load on the crank 3 that is acting in one direction and the tensile force of the spring 16, the injection blade 6 moves around the pivot point 13 of the support shaft 15 and interlocks. Vibration amplitudes will be applied within the play of the mechanism.

Further, when the injection depth is shallow, when the injection blade 6 leaves the soil surface, the resistance to the crank 3 is suddenly released, and at this time, the vibration amplitude of the spring 16 is accompanied.

By continuing the above-described cycle, as the machine moves forward, the chemical solution in the tank 9 is gradually forced into the soil through the injection blade 6 by the operation of the plunger pump 5.

(Effects) In other words, according to the method, the injection blade moves forward and backward with the aircraft and is given a vibration amplitude by the spring, which prevents soil from adhering to or clogging the injection hole of the injection blade. This improves the separation of the injection blade from the soil, making it possible to perform the injection of chemical solutions very well.Although the overall structure is simple, it is possible to perform efficient injection, making it one of the most popular agricultural working machines of this type. It is highly practical and can be used in a wide range of applications.

Furthermore, since this invention links a vibrating drug injection blade with a plunger pump for forcibly feeding drugs, the plunger pump can be driven using the reciprocating vibration mechanism of the injection blade, making it possible to drive the plunger pump using a single drive. There are advantages such as equipment.

In addition, since the acting force from the soil is used as the driving source for the rearward movement of the injection blade, even if the drive wheel slips, the chemical solution will not be injected in the same place, making uniform injection possible.

In other words, the plunger pump operates only when the injection blade reciprocates, making it possible to perform efficient injection work.
