Description

[Detailed explanation of the invention] This invention involves driving a fumarole pipe into the soil where plants are planted, and explosively injecting compressed air in the pressure storage tank into the soil from the fumarole hole of the fumarole pipe, thereby growing the plants. The present invention relates to a blower type deep cultivator that forms cavities or pores in the soil that facilitate the supply of moisture and nutrients to the roots, and supplies air injected into the holes to the roots of plants to promote plant growth.

The purpose of this invention is to generate strong driving force using a mechanically driven hammer device with a simple structure, thereby increasing work efficiency.

Conventionally, there are two methods for inserting fumarole pipes into the soil: manual driving methods in which the fumarole pipes are driven into the soil using a pressure storage tank, and power turning methods in which the fumarole pipes are rotated and spiraled like an awl. .

Manual driving type requires heavy labor as it requires repeated deep plowing, and the work speed is slow and inefficient.

In addition, in the powered swing type, the diameter of the perforation increases due to the lateral vibration of the fumarole pipe as it rotates, creating a gap between the perforation and the fumarole pipe, causing ejection from the fumarole. Because compressed air blows through the gaps to the ground, the pores that form in the soil are small, and deep plowing ability is extremely reduced.

In addition, the reaction force of the rotation drive of the fumarole pipe tends to cause the pressure accumulation tank to rotate in the opposite direction, and the operator must firmly hold down the bundle so as not to succumb to this reverse rotation force.
It's hard work.

In order to solve this deficiency, the applicant previously proposed a structure in which the hammer is driven by an air hammer mechanism, but in this case, the structure would be complicated and the impact would be severe.
Advanced technology is required to reduce manufacturing costs.

In order to improve the above-mentioned drawbacks, the present invention uses a mechanically driven hammer device with a simple structure to drive the fume pipe.

Next, an embodiment of the present invention will be described based on the drawings.

As shown in Fig. 1, the powered perforation-type fumarole-type deep cultivator has a pressure accumulator tank T with a pair of left and right bundles H, supports a housing 5 at the bottom of the pressure accumulator tank T, and has a perforation and blowhole on the underside of the housing 5. It has a structure in which pipes 1 are arranged and these are supported by a pressure accumulator tank T.

Drill the fumarole pipe 1 into the soil with a mechanically driven hammer device M, and after driving it in thoroughly, press the lever 2 of the right bundle H.
After accumulating compressed air from the compressed air source A to the accumulator tank T to a predetermined pressure, operate the valve opening lever 3 to open the injection control valve ■, and direct the compressed air from the accumulator tank T to the air guide hole. 16, and from the fumarole hole 4 at the tip of the fumarole pipe 1 to the root to deeply plow the soil.

As shown in FIGS. 3 and 4, the mechanically driven hammer device M is attached to a housing 5 that is vertically slidably housed in the lower part of the pressure storage tank T, and is configured as follows.

That is, a pair of rotating shafts 7 are installed horizontally and symmetrically in the upper part of the machine room 6 in the housing 5, and the rear end of the rotating shafts 7 is connected to the output shaft of an electric motor 8, which is a prime mover. Two rotary cams 9 are attached to the shaft 7.

On the other hand, the upper end of the fumarole pipe 1 is slidably inserted through the lower central part of the housing 5, and its top part 1a faces the machine room 6, and the hit part R is fixed to the top part 1a of the fumarole pipe 1. be done.

The hit portion R is fitted into the lower part of the machine chamber 6 so as to be slidable in the vertical direction, and is in contact with the circumferential surface of the rotary cam 9 while being weakly elastically biased upward by an auxiliary spring 10 .

When the left and right pair of electric motors 8 are rotated symmetrically, the left and right pair of rotary cams 9, each having two cams, rotate symmetrically and the striking portion S is rotated symmetrically.
This is a structure in which the blow pipe 1 is driven by hitting the hit portion R at a high rotational speed.

In order to prevent the above-mentioned impact force at the time of impact from directly propagating to the bundle H, the parts below the hammer device M are supported in a pressure accumulating tank T in a vibration-proof manner via a vibration isolating device C as described below.

That is, the center part of the bottom wall 11 of the pressure storage tank T is bulged inward in a cylindrical shape to form a spring mounting chamber 12, and a strong buffer spring 13 is installed therein to press the housing 5 downward. At the same time, by providing a gap between the bottom wall 11 and the upper surface of the housing 5, the reaction force propagated to the rotating shaft 7 at the time of impact can be stopped by both hands holding the bundle H via the buffer spring 13. do.

Furthermore, by driving while rotating the fumarole pipe 1, the frictional resistance between the fumarole pipe 1 and the soil is reduced as much as possible, and in order to achieve highly efficient driving, the worm gear 14 of the rotating shaft is used to drive the spur gear 15. It is formed so that the hit part R is rotated in a fixed direction through the hit part R.

Here, in order to prevent damage to gears due to impact, the spur gear 15 is rotatably attached to the housing 5.
The top of the hit portion R is inserted into the square hole No. 5 so as to be vertically slidable and rotationally transmittable.

In addition, an air guide hole 16 communicating with the pressure accumulator tank T is formed in the housing 5 and the fumarole pipe 1, and the air guide hole 16 is communicated with the fumarole hole 4, and the injection hole 16 is opened and closed at the lower side of the housing 5. A control valve V is provided, and the injection control valve V and the valve opening lever 3 are operated to open the valve.

Further, since the pressure accumulating tank T and the housing 5 move relative to each other, the structure is such that the air guide hole 16a and the housing 5 slide.

The four rotary cams 9 are arranged symmetrically in plan view with respect to the center of the hit portion R, and are formed so that each rotary cam 9 hits the hit portion equally.

However, two rotary cams 9 may be attached symmetrically to the central axis of the blow pipe 1, and in short, it is sufficient to attach at least one rotary cam.

The driving frequency, that is, the rotation speed of the rotary shaft 7, can be set as appropriate, but it is preferably about 5 to 10) T per second, and the electric motor 8 is a small motor with a reduction gear, and is powered by both AC and DC power sources. It is better to make it operational.

In addition, since the bundle H is gripped and pressed while driving into the hole, the rotating cam 9 does not impact the part R to be hit.
Since the rotating cam 9 drives the hammer while always being in contact with the hit portion R, the hammer can be driven quietly with almost no impact noise being generated.

Note that reference numeral 17 is a switch for starting and stopping the electric motor.

An air motor can be used instead of the electric motor 21 as the prime mover, or a small prime mover (small internal combustion engine) can also be used.

Since the present invention is configured as described above, it has the following effects.

1. The fumarole pipe is driven in by a mechanically driven hammer device, which provides a powerful driving force, allowing highly efficient deep plowing even in areas with poor soil conditions.

Moreover, since no reaction force is generated from the fumarole tube rotation and there is no leakage of compressed air, deep plowing can be carried out easily and reliably.

2 Mechanically driven hammer devices are powered by a prime mover such as an electric motor.
Since it has a simple structure consisting of simple parts such as a rotating shaft, gears, striking parts, and struck parts, it is highly durable and can be easily repaired in the event of a breakdown.

Therefore, the operating rate of the deep tiller is improved and running costs are also reduced.

3 A mechanically driven hammer device has a rotating shaft attached to the housing horizontally, a rotating cam is fixed to the rotating shaft, and the striking part made of this rotating cam is brought into contact with the struck part of the upper end of the perforation and blow pipe. Since the striking part and the struck part are made to face each other as much as possible, it is possible to drive with the striking part and the struck part constantly in contact with each other, and not only does the operator receive no impact due to the driving reaction force, but also no impact noise is generated.
