Description

[Detailed description of the invention] This invention relates to a pollination machine that can send a mixed airflow of pollen and pressurized air over a considerable distance.

Currently, most of the artificial hybridization of fruit trees such as peaches, apples, pears, plums, and persimmons relies on manual labor.

In other words, apply pollen to something like a bristle brush,
This was used to press each petal onto the desired petal, but this method requires a lot of effort and time, and may damage the petal. Furthermore, on rainy days, the bristle brush gets wet and cannot be used.

As a solution to this problem, a pollination machine that sprays a mixed air flow of pollen and pressurized air onto the target flower petals has been proposed, for example, in Japanese Patent Publication No. 35-10660,
Various proposals have been made, including Publication No. 51-13407. However, although all of these systems ensure the wind pressure of pressurized air, they use a diaphragm structure to create and pressurize the air, so the air volume is absolutely insufficient, and it is difficult to put them into practical use. do not have.

This is because the conditions for mating, that is, the position and height of the petals, and the effects of wind, etc., cannot all be the same, and no matter what these conditions are, in order to ensure good pollination, it is necessary to use a considerable amount of mixed airflow. This is because it must be able to fly far.

On the other hand, Japanese Patent Application Laid-open No. 53-2236 discloses a system that uses a blower fan to generate wind.
These are axial fans with a weak air volume, and since the distance between the fan and the pollen container is long and not all of the air is sent into the pollen container, a sufficient amount of air cannot be secured. Furthermore, it has a structure that makes it impossible to control the amount of pollen.

In this sense, a power sprayer that utilizes the powerful jetting force can be seen in, for example, Publication No. 1973-33722, but this time, on the other hand, the air volume (also known as wind pressure) is too large and there is a risk of damaging the petals. There is, and
It has also been pointed out that the pollen density in the air mixture becomes too low, reducing pollination efficiency.

Therefore, this idea was developed as a source of pressurized air.
By using a small dedicated blower fan, it is possible to blow a low-pressure mixed airflow with high pollen density over a considerable distance, and it is also possible to softly touch the target petals.

Embodiments of this invention will be described below with reference to the drawings. In the accompanying drawings, FIG. 1 is a cross-sectional right side view of a pollinator according to this invention, and FIGS. 2 and 3 are also partially cross-sectional views. Front view and partially sectional left side view,
FIG. 4 is a perspective view of a storage box for dry batteries, and FIG. 5 is an electric circuit diagram for controlling a DC motor.

The pollinator has a spout 2 at the front of the upper part of the body 1.
Motor accommodating tubes 3 are respectively projected from the rear, and a pollen container 4 is connected to the lower part of the body 1 by screwing or the like. Note that pollen is stored in this pollen container 4, and
When in use, it also serves as a grip.

Two passages, namely a blow passage 5 and a blowout passage 6, are formed in the body 1. Of these, the blow passage 5 exits from a fan storage chamber 7 also formed in the body 1. The ejection passage 6 extends into the pollen container 4, bends horizontally forward on the way out of the pollen container 4, passes through the ejection tube 2, and reaches the ejection port 8 at the tip. Note that a ventilation sleeve 9 whose cut end is formed obliquely toward the center of the pollen container 4 may be fitted to the end of the ventilation passage 5.

A radial blower fan 1 is installed in the fan storage chamber 7.
0 is housed with its blade tip facing the starting end of this ventilation passage 5, and this is a DC motor 12 fixed in the motor housing cylinder 3 by two rings 11, 11'. (hereinafter referred to as the motor 12) is directly connected and supported to the shaft of the motor 12. Note that the rear part of the motor housing cylinder 3 is covered with a cap 13.

The motor 12 is driven by a separately installed dry cell battery 14, and is started and stopped by a switch 15.
Switch box 16 formed on the side of body 1
is housed within.

It goes without saying that a cord 17 is required to connect the switch 15, motor 12, and dry battery 14, but this cord 17 should be connected to each other by making appropriate holes in the body 1. . However, in order to connect the dry battery 14 continuously, the cord 17 must be taken out to the outside, but a hole 18 is made in the cap 13 and the cord 17 is made to extend from there.

As described above, when the push button 19 of the switch 15 is pressed, the power is turned on and the blower fan 10 is driven by the motor 12. Mouth 20,2
Since an air intake chamber 21 communicating from 0' is provided, the air sucked from the air intake ports 20, 20' is pressurized by the ventilation fan 10 and sent into the pollen container 4 through the ventilation passage 5.

Since pollen is stored in the pollen container 4, the pressurized air stirs and mixes the pollen, forms a mixed air flow with the pollen, and sends it out to the jetting passage 6, as well as jetting it out from the jetting port 8. It is.

Incidentally, the adjustment of the amount of jetting of the mixed air flow is performed by the adjustment mechanism 22 that adjusts the amount of pressurized air blown through the ventilation passage 5.

The first possible adjustment mechanism 22 is:
A bypass passage 23 is provided that short-circuits the blowing passage 5 and the blowing passage 6 leading to the pollen container 4, and an air passage switching valve 2 is provided at the branch point between the bypass passage 23 and the blowing passage 5.
4 will be installed. That is, by turning the knob 25 that switches the air path switching valve 24 and adjusting the volume of pressurized air overflowing into the bypass passage 23, the volume of pressurized air sent to the pollen container 4, and therefore , the air volume of the air mixture jetted out from the jetting port 8 can be adjusted.

Next, what can be considered as the adjustment mechanism 22 is:
By connecting a variable resistor 26 in series with the motor 12, the voltage applied to the motor 12 can be changed, and the rotational speed of the motor 12 and therefore the fan 10 can be changed. Note that it is clear that the amount of air mixture ejected from the ejection port 8 can be adjusted by changing the rotational speed of the blower fan 10.

By the way, regarding the installation location of the dry battery 14 mentioned above, it should be stored in a suitable box 27 and tied around the waist with a belt 28 or the like, or with a string or the like so that it can be carried while working. Just hang it from your shoulder.

As mentioned above, this invention uses the blower fan 10 as the air source to create a mixed airflow of pollen and pressurized air. It is possible to fly it quite far while maintaining the wind pressure. In this respect, it will be obvious when compared with the conventional diaphragm pumps and manual pumps described above, which do not have enough air volume and cannot be blown far.

In addition, since it is sufficient to use the minimum capacity of the blower fan 10 and motor 12 that exhibit this performance, it is necessary that their capacity is small, and this is combined with the fact that the dry battery 14 is placed separately. ,
The pollinator itself is lightweight and compact, can be provided at low cost, and is easy to operate.

Furthermore, even though the air mixture can be blown over long distances, as mentioned above, the amount of air emitted can also be finely adjusted.
It is possible to respond optimally depending on the position and height of the petals, weather conditions, etc.

In addition, by providing the adjustment mechanism 22 as described above, it is expected that by adjusting the air path switching valve 24 that constitutes the adjustment mechanism 22, the amount of pollen in the ejected airflow can be adjusted arbitrarily while working.
