Description

[Detailed explanation of the idea] This invention relates to a soil disinfection device.

2. Description of the Related Art Conventionally, there is a soil disinfection machine that is connected to a tractor by a three-point hitch type connection means for spraying a disinfectant onto cultivated soil.

However, this soil disinfection machine is driven by a tractor, and it is extremely difficult to connect it with other working machines.

Therefore, it is impossible to disinfect while performing other tasks, resulting in an impossible rate.

Furthermore, such a sterilizer that is towed by a tractor is large-scale and has a complicated structure.

Furthermore, when the PTO shaft of the tractor is used to extract driving force, the rotation of the PTO shaft is not necessarily proportional to the traveling speed, and as a result, the amount of disinfectant sprayed cannot be made to correspond to the traveling speed.

Furthermore, even if power is extracted from the drive wheels of the tractor to spread the disinfectant, there is a drawback that the disinfectant will be sprayed in unnecessary areas as long as the tractor is running.

This idea was developed in consideration of the points mentioned above, and it is possible to spray disinfectant while connecting other working machines, has a simplified structure, and can spray disinfectant in an amount proportional to the traveling speed of the tractor. It is intended to be used as a soil disinfection device that can be used to spread soil.

An embodiment of this invention will be explained based on the drawings.

1 is a tractor, and a rotary 2 is installed at the rear of this tractor 1.
and other work equipment are connected.

A frame 4, which is a fixed part, is fixedly provided at the rear of the body 3 of the tractor 1.

As shown in FIG. 2, this frame 4 consists of a vertically long pole 5, an arm 6 fixed to the lower end of the pole 5 and extending forward, and a shelf 7 fixed to the upper end of the pole 5.

A tank 8 for storing a disinfectant is placed on this shelf 7.

Further, an operating rod 9 is rotatably connected to the arm 6 by a pin 10.

This operating rod 9 is biased clockwise by a spring 11.

A drive body 15 having a plurality of protrusions 14 on the outer periphery of the side surface is fixedly fitted to the axle 13 of the rear wheel 12 of the tractor 1.

A protrusion 16 that interferes with these protrusions 14 is fixed to one end of the operating rod 9.

A diaphragm pump 18 serving as a pump is fixed to the upper part of a stay 17 which is supported in a long hole by the operating rod 9 and whose lower part is hingedly connected to the arm 6.

Further, the operating rod 9 includes the pin 10 and the stay 17.
the pin 10 with a distance greater than the distance between the pin 10 and the mounting part of the
It has a piston part 19 attached at a defined distance from the piston part 19.

This pump 18 is driven by the reciprocating motion of a piston portion 19, and its suction side is connected to the tank 8 through a hose 20, and the hose 21 connected to its discharge side is connected to the upper surface of the transmission case 22 of the rotary 2. It extends between the tilling claws 23 and the ridge shaper 24, and a nozzle 25 is provided at its tip.

Further, an adjustment bolt 26 is screwed into the tip of the arm 6, and the adjustment bolt 26 comes into contact with the tip of the operating rod 9 to determine the clockwise movement range of the operating rod 9, and also functions as a release device. There is.

Further, the lift arm 27 of the tractor 1 and the operating rod 9 are connected by a wire 28 which also functions as a release device.

The length of this wire 28 is slack so as not to impede the rotation of the operating rod 9 when the lift arm 27 is lowered, and is tensed when the lift arm 27 is raised to pull the operating rod 9 counterclockwise. determined by the length.

In such a configuration, when the tractor 1 travels, the rotary 2 performs plowing work and the ridge shaper 24 performs plowing work.

On the other hand, each time the protrusion 14 moves by one pitch as the driving body 15 rotates, the operating rod 9 rotates counterclockwise and returns to its original position by the force of the spring 11.

As a result, the pump 18 moves together with the stay 17, but since the movement of the piston part 19 is larger due to the lever ratio, the piston part 19 reciprocates with respect to the pump 18 to drive the pump 18.

In other words, the disinfectant is sprinkled on the plowed areas.

Therefore, the amount of disinfectant to be sprinkled is proportional to the traveling speed of the tractor 1, and is sprinkled in just the right amount.

Further, when the lift arm 27 is raised for turning or the like, the wire 28 is tensed and the operating rod 9 is pulled up in the counterclockwise direction.

That is, the protrusion 16 of the operating rod 9 is the protrusion 14 of the driver 15.
located outside the trajectory of

This prevents the disinfectant from being sprayed where it is not needed and prevents the disinfectant from being wasted.

If a member for adjusting the length of the wire 28 is provided at the middle or both ends of the wire 28, the reciprocating movement of the operating rod 9 can be stopped without raising the lift arm 27.

Alternatively, by screwing in the adjustment bolt 26, the operating rod 9 can be retracted from the drive body 15, and the work of spraying the disinfectant can be stopped.

This allows other tasks to be carried out without having to remove the series of disinfectant supply devices.

Furthermore, it is easy to loosen the bolt 29, remove the arm 6 together with the operating rod 9 from the pole 5, and remove the tank 8, which also allows the work of dispensing disinfectant to be stopped and other work to be performed.

Although the operating rod 9 is shown in a rotating state, it may also be configured to reciprocate in a linear direction.

In this case, the pump 18 can be fixed to a fixed part such as the shelf part 7, and the operating rod itself that reciprocates linearly can function as a piston part.

Furthermore, the number of protrusions 14 on the driver 15 can be increased or decreased depending on the capacity of the pump 18, and may be one.

Alternatively, the operating rod 9 may be reciprocated by a cam-like driving body.

As mentioned above, this invention uses the drive body fixed to the axle of the tractor as the drive source to drive the pump, so it is possible to spray disinfectant in just the right amount and amount depending on the movement of the tractor.
The tank, drive body, pump, operating rod, etc. are installed on the tractor side, so other work equipment can be attached to it.This allows you to spray disinfectant while performing other tasks, improving efficiency. Unlike the conventional soil disinfection machine that is towed by a tractor, it is possible to eliminate the need for a traveling mechanism or a traction coupling mechanism, making it possible to simplify the structure and make it more compact. If it is located in a position where it can be retracted from the operating rod, it can prevent the reciprocating movement of the operating rod, thereby preventing waste of disinfectant.
