[0001] Fluid Spreader for Rice Transplanter [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rice transplanter mounted on a rice plant and a fluid distributing device for dispersing fluids such as pesticides and fertilizers together with a broaching operation.

The process of planting the seedlings from the germination of the seedlings is generally carried out in the following sequence. In the first place, rice seeds are sown in the box made of seedlings, germinated, and grown until they reach a certain size. Here, the box used is called a seedling box and is made to have a certain standard. Next, we plant seedlings grown in a certain size in a seedling box in a rice planting plant.

By the way, granular pesticide for pest control relief is dispersed in seedling auction just before planting seedling in rice field. Conventionally, such pesticide scattering has been carried out, for example, as disclosed in Japanese Patent Application Laid-Open No. 8-281157, before the seedlings are placed in the rice plant using acid aeration.

However, since the aging of agriculture workers is progressing in recent years, it is desirable to reduce the number of the agricultural work even a little because aggravated agricultural work is reluctant.

However, in the above-mentioned conventional technique, there is a problem that the pesticide is dispersed in the seedling box and then the seedlings are planted in the rice paddy field in the rice paddy field.

Here, since the reciprocating operation of the lathe bearing the tombstone works together with the planting operation of the rearing machine, for example, if the planting operation is slow, the reciprocating operation of the lathe bearing the tomb becomes slow, The reciprocating operation of the shelf loaded with the wafer is accelerated. Therefore, regardless of the planting speed, it is possible to distribute the desired amount of fluid to the seedling by the spreading mechanism.

According to a fourth aspect of the present invention, there is provided a brothel-type fluid distributing apparatus according to the second aspect of the present invention, wherein the scattering operation control mechanism is attached to a shelf containing a grave provided in the rearing station, A proximity switch for detecting an approach of an operating instrument unit that moves with the reciprocating operation of the shelf in which the seedling is placed and which is attached to the planting machine body toward the shelf carrying the seedling, And a control unit for operating the dispensing mechanism on the basis of the detection of the operation instrument unit by the proximity switch.

According to the fluid dispensing apparatus of the herbicide-mounting type according to the present invention, in the course of reciprocating movement of the operating instrument together with the shelf containing the seedling, the proximity switch detects the approach of the operating instrument and the proximity switch detects the approach of the operating instrument The dispersing mechanism is operated with its output as an instrument. Therefore, it is possible to distribute the desired amount of fluid to the grave by the distributing mechanism.

According to a fifth aspect of the present invention, there is provided a brothel-mounted fluid fountain apparatus according to any one of the second to fourth aspects, further comprising: at least one acid aerator for dispersing a fluid; And the opening and closing of the electromagnetic valve is controlled by the scattering operation control mechanism. The present invention has been made in view of the above problems.

According to the fluid distributing apparatus of the herbicide-mounting type according to the present invention, since the opening and closing of the electromagnetic valve is controlled by the dispersing operation control mechanism, it becomes possible to disperse the fluid from the dispersing device intermittently in cooperation with the seeding operation.

The pressure in the holding container rises when at least the fluid is supplied from the feeding pump in a state in which the solenoid valve is closed.

According to the metering device-mounted fluid spray device of the present invention, when at least the electromagnetic valve is closed, fluid is supplied from the supply pump to the holding container, and the pressure in the holding container rises. When the solenoid valve is opened from this state, the fluid is scattered with pressure in the holding container from the diffuser toward the outside. For this reason, the fluid is dispersed at a stable pressure regardless of the pulsation of the supply pump, and the fluid can be scattered at a desired position of the shelf on which the seedlings are placed.

According to a seventh aspect of the invention, there is provided a brothel-mounted fluid distributing device according to the fifth aspect of the present invention, wherein the distributing mechanism is provided with a scattering nozzle for dispersing a fluid and a rocking mechanism for rocking the scattering nozzle, Is controlled by the above-described dispersing operation control mechanism.

According to the rice flourishing type fluid distributing apparatus according to the present invention, in a state in which the solenoid valve is closed, the pressure in the holding vessel rises together with the fluid being supplied into the holding vessel by the feed pump. When the pressure in the holding container reaches a predetermined value, the pressure adjusting valve is closed to stop the inflow of the fluid into the holding container. Therefore, the pressure in the holding container does not rise excessively, and breakage of the holding container can be prevented.

When the pressure regulating valve is closed, the fluid drawn up from the supply pump is returned to the reservoir by the circulation means. Further, when the flow rate of the feed pump for a unit time is larger than the flow rate obtained by passing the pressure regulating valve for a unit time even in a state where the pressure regulating valve is open, a part of the fluid pulled up by the feed pump is circulated And returned to the storage section by the means.

As described above, when the outflow and inflow of the fluid to the storage portion are performed, a flow is generated in the storage portion, and it becomes possible to stir the fluid in the storage portion.

[Example]

1 to 6 illustrate an embodiment according to the present invention in which a rice flourishing type fluid distributing apparatus (hereinafter, abbreviated as "dispersing apparatus") according to this embodiment is a rice planting apparatus In fact, it is spraying the pesticide liquid on the tomb. This pesticide liquid is obtained by dissolving granular pesticides in water at a predetermined concentration and is intended for pest control.

As shown in Fig. 1, this dispersing device is provided with a storage tank (storage portion) 1 for storing the pesticide solution, a dispersing mechanism 2 for dispersing the pesticide solution together with the transplanting operation, 1 to the dispersion mechanism 2 and a dispersion operation control mechanism 4 that operates based on the reciprocating operation of the shelf S bearing the seedlings and intermittently performs dispersion of the pesticide solution by the dispersion mechanism 2 And a power supply mechanism 5 for supplying power for operation.

The dispersion mechanism 2 includes a chamber (holding container) 6 for temporarily holding the pesticide solution supplied by the supply pump 3, a plurality of acid dissolvers 7 for spraying the pesticide solution toward the lower end of the shelf S bearing the seedling, And a plurality of hoses 9 connecting the solenoid valve 8 and the diffuser 7 to each other.

The chamber 6 is a container in which the pressure inside the chamber 6 is increased when the pesticide liquid is supplied from the supply pump 3. By opening the solenoid valve 8, the pesticide liquid is dispersed from the acid aerator 7 with the pressure in the chamber 6.

The pick-up 7 is fixed to a support frame 10 provided on the rear side of the shelf S on which the seedlings are placed. The support frame 10 is fixed to a gear box B for operating the nail P for picking up the seedlings.

The open / close state of the solenoid valve 8 is controlled by the scattering operation control mechanism 4. When the solenoid valve 8 is opened, the pesticide liquid is supplied from the chamber 6 to the diffuser 7 through the hose 9. [

The hose 9 is formed of a rubber that can be elastically deformed easily, and can be easily installed according to each part of the herbicide.

As shown in Fig. 2, a plurality of the diffusers 7 are arranged at equal intervals in accordance with the number of branches (corresponding to the areas S1 to S5 in the figure) of the shelves S on which the grains are placed.

A large number of electromagnetic valves 8 are provided in accordance with the number of switching switches for changing the number of racks S on which the seedlings used for the moving works are placed. This is because the areas S1, S2 and S4, S5 of the shelf S on which the tombstones are placed can change their use states at the same time in one changeover switch. Therefore, the hose 9 connecting the one solenoid valve 8 and the two diffusers 7, 7 has a branched shape.

As shown in Figs. 3 and 4, the acid aerator 7 includes a dispersion nozzle 11 for dispersing the pesticide solution supplied from the hose 9 toward the shelf S bearing the seedlings, and a dispersion nozzle 11 for intermittently oscillating the dispersion nozzle 11 A swinging mechanism 12, and a housing case 13 for accommodating the swing mechanism 12. The scattering nozzle 11 is formed in a substantially L-shaped cylindrical tube. One end of the scattering nozzle 11 is connected to the hose 9 and protrudes outwardly from the bottom portion 13a of the housing case 13 at the same time. The front end portion 11b of the scattering nozzle 11 is capable of scattering the pesticide liquid toward the direction (Z direction) of the shelf S on which the seedling is placed.

The rocking mechanism 12 includes a plate-like member 14 fixed to the base 11a of the scattering nozzle 11, a spring 15 provided at one end in the longitudinal direction of the plate-like member 14, and a solenoid 16 provided at the other end .

One end of the spring 15 is fixed to the plate-like member 14, and the other end thereof is fixed to the accommodation case 13.

The solenoid 16 is composed of a solenoid body 16a and a drive shaft 16b, and its operation is controlled by a scattering operation control mechanism 4. [ The solenoid main body 16a is fixed to the accommodating case 13.

In a state in which the solenoid 16 is not operating, the driving shaft 16b is in a state of being stretched by the tension of the spring 15. [ When the solenoid 16 is operated, the drive shaft 16b is drawn into the solenoid body 16a fixed to the housing case 13, so that the plate-like member 14 is rotated about the fixed position with the base portion 11a of the scattering nozzle 11 And the dispersion nozzle 11 is oscillated.

A check valve 17 is provided on the halfway of the hose 9 inserted in the housing case 13 to prevent the backflow of the pesticide solution from the dispersion nozzle 11 side toward the hose 9 side. The check valve 17 is for preventing air from being mixed into the hose 9 from the scattering nozzle 11 side and holding a certain amount of pesticide solution dispersed from each acid aerator 7.

As shown in Fig. 1, the scattering operation control mechanism 4 is composed of an operation instrument unit 21 fixed to a lathe S bearing a seedling and serving as an instrument of operation of the dispersing mechanism 2, and an operation instrument unit 21 A proximity switch 22 for detecting the approach of the proximity switch 22, and a control section 23 for operating the dispensing mechanism 2 on the basis of the detection of the proximity switch 22.

5, the operating instrument part 21 is composed of a plurality of metal bolts 25 attached to a rod 24 reciprocating with a shelf S bearing a seedling, And is attached parallel to the moving direction of the shelf S on which the seedlings are placed.

The bar 24 has a U-shaped cross section, that is, a so-called channel shape, and is fixed to the beam portion Sx of the shelf S on which the seedling is placed by using the lock belt 26 with the central groove portion 24a facing forward. The plurality of bolts 25 are attached to a portion corresponding to the bottom surface of the groove portion 24a and arranged at equal intervals in a range slightly narrower than the movement width of the shelf S on which the tombstones are placed.

The proximity switch 22 has a detecting portion 22a which is movably attached in the longitudinal direction of the bar 24 and detects the approach of the bolt 25 moving along the reciprocating operation of the shelf S bearing the tombstone by the action of a magnetic line of force. The detecting portion 22a is fixed to the bottom surface of the groove portion 24a with respect to a carriage 27 movably attached along the rod 24. [

Two carrier wheels 27a are attached to both sides of the carrier 27. These carrier wheels 27 are rotatable in the longitudinal direction of the bar 24 by being rotatably fitted to the rail portions 24b provided on the bar 24.

The proximity switch 22 is moved relative to the rod 24 together with the wheel 27, and is switched when the detection unit 22a detects the approach of the bolt 25. [

As shown in Fig. 1, the control section 23 is provided with a main switch 23a for operating the supply pump 3 and a changeover switch 23b for enabling the solenoid valve 16 and the solenoid valve 16 to operate. In a state in which the main switch 23a is turned on, power is supplied from the power supply mechanism 5 to the supply pump 3, and when the switch 23b is turned on, the solenoid valve 16 and the solenoid 16 Is ready for operation.

Between the supply pump 3 and the chamber 6, a pressure regulating valve 31 for keeping the pressure in the chamber 6 constant is provided. Therefore, even if the supply pump 3 continues to operate, the pressure in the chamber 6 is excessively increased, thereby preventing the chamber 6 from being damaged. A hose (circulation means) 32 is provided between the supply pump 3 and the pressure regulating valve 31 for returning the pesticide liquid which has been drawn up by the supply pump 3 but not supplied into the chamber 6 to the storage tank 1.

A method of using the dispersing device constructed as described above will now be described.

At first, we put pesticide liquid into storage tank 1 while putting seedling bunch raised in seedling box on shelf S carrying seedling. Next, the main switch 23a is turned on to operate the supply pump 3, and the change-over switch 23b is turned on so that the spreading mechanism 2 can operate based on the switching of the adjacent switch 22.

At this time, the pesticide solution is supplied from the reservoir 1 to the chamber 6 through the supply pump 3, and the pressure in the chamber 6 rises. When the pressure in the chamber 6 reaches a predetermined value, the pressure regulating valve 31 is closed and the supply of the pesticide solution to the chamber 6 is stopped. Therefore, the pesticide liquid drawn up by the supply pump 3 is returned to the storage tank 1 through the hose 32.

When the flow rate of the feed pump 3 for a unit time is larger than the flow rate obtained by passing the pressure regulating valve 31 for a unit time even in the state where the pressure regulating valve 31 is open, A portion of the liquid is returned to the reservoir 1 through the hose 32.

Thus, when the pesticide solution flows out and flows into the storage tank 1, a flow occurs in the storage tank 1, and the pesticide solution in the storage tank 1 is stirred.

Then, when the weed plant is started by the weeding period, the shelf S carrying the weeds moves sideways (X direction) together with the scraping operation by the scraping nail P as shown in Fig. Here, the area Sb where the scraped nails P are scraped together is a portion surrounded by a broken line in the drawing, among the shelves S with the seedlings, and each scraped area Sb located at the lower end Sa of the shelf S, Are sequentially scraped by the scraped nails P simultaneously with the movement of the shelf S carrying the tombs. Thereafter, when the seedling of the lower end Sa is scratched, the seedling bundle slides toward the lower end portion Sa side of the shelf S carrying the seedling, and the nail P scraped as the shelf S carrying the seedling moves in the Y direction sequentially scoops the seedlings.

The rod 24 moves laterally with the shelf S carrying the seedling, and when the plurality of bolts 25 attached to the rod 24 pass the proximity switch 22, the proximity switch 22 is intermittently switched. Then, with the switching of the proximity switch 22, the dispersion mechanism 2 distributes the pesticide solution.

That is, when the proximity switch 22 is switched, the solenoid valve 8 is temporarily opened so that the pesticide solution is scattered from the scattering nozzle 11 toward the shelf S bearing the seedling, and the drive shaft 16a of the solenoid 16 reciprocates once to oscillate the scattering nozzle 11 .

At this time, irrespective of the pulsation of the supply pump 3, since the pesticide solution is scattered from the scattering nozzle 11 at a constant pressure from the chamber 6, the amount of the pesticide solution dispersed is constant. Then, the scattering nozzle 11 causes the pesticide solution to be scattered on a predetermined portion of the shelf having the seedlings corresponding to the swing range. Here, the predetermined portion shows each region of the cumulative scattering regions Sc1 to Sc4 obtained by dividing the scattering region Sc located above the lower end Sa of the shelf S carrying the seedlings, as shown in Fig.

During the movement of the shelf S carrying the seedlings in the X direction, the pesticide solution is dispersed intermittently every time the proximity switch 22 detects, and the pesticide solution is sequentially sprayed from the collective scattering region Sc1 to the collective scattering region Sc4 .

The scattering of the pesticide solution is similarly performed when the shelf S bearing the seedlings moves in the Y direction, and the pesticide solution is dispersed sequentially from the collective scattering region Sc4 to the collective scattering region Sc1.

In the case where the planting speed by the weaving machine changes, the moving speed of the shelf S carrying the weaving machine is slowed together, so that the detection time interval of the bolt 25 by the proximity switch 22 changes. Therefore, the time interval of dispersing the pesticide solution by the dispersing mechanism 2, which occurs together with the switching of the proximity switch 22, also changes.

While the plowing operation by the plowing machine is continued, the pesticide solution is intermittently dispersed from the dispersing mechanism 2 in the above-mentioned area, but when the planting operation is stopped, the reciprocating movement of the shelf S carrying the seedling is stopped, 2 stops and the dispersal of the pesticide solution is stopped.

As described above, according to such a rice flouring-type fluid distributing device, since the pesticide liquid is scattered on the seedlings together with the transplanting operation by the rice paddy, it is possible to reduce the number of operations for agricultural work and to reduce the physical burden of agricultural workers It is possible.

Further, in the process of reciprocating movement of the operating instrument part 21 together with the lathe S bearing the seedling, the electromagnetic valve 8 of the spreading mechanism 2 operates with the output of the proximity switch 22 every time it detects the approach of the bolt 25 , The dispersing mechanism 2 can disperse the pesticide liquid intermittently in cooperation with the planting operation by the rice planting period. Thus, irrespective of the speed of the planting operation, a desired amount of the pesticide solution can be dispersed by the dispersing mechanism 2 in the seedlings.

Further, by providing the pressure adjusting valve 31, the pressure in the chamber 6 is not excessively increased, and it is possible to prevent the chamber 6 from being damaged.

Particularly, the pressure in the chamber 6 becomes constant by the supply pump 3 and the pressure adjusting valve 31, and when the solenoid valve 8 is opened, the pesticide liquid flows outwardly from the scattering nozzle 11, 6, the flow rate of the pesticide solution dispersed from the acid aerator 7 becomes constant. Therefore, it becomes possible to distribute a predetermined amount of the pesticide liquid to a desired position of the shelf S on which the seedlings are placed.

Particularly, when the pesticide solution is dispensed, since the swinging mechanism 12 swings the dispensing nozzle 11, it is possible to dispense the pesticide solution over a wide range of the shelf S on which the seedling is placed by a single dispensing operation.

Further, since the pesticide liquid in the storage tank 1 is stirred by the supply pump 3 and the hose 32, the granular pesticide contained in the pesticide liquid is prevented from precipitating in the bottom portion of the storage tank 1 and the concentration of the pesticide liquid And it becomes possible to make it uniform.

Further, in the above embodiment, the acid aerator 7 is provided with the scattering nozzle 11 for dispersing the pesticide solution while swinging, but the present invention is not limited to this, and it is also possible to disperse a certain amount of the pesticide solution into the seedlings placed on the shelf S, It is preferable. For example, a spray nozzle for dispersing the pesticide liquid spray may be provided, or the pesticide liquid may be intermittently flowed from above the shelf S containing the seedlings.

In addition, although a plurality of diffusers 7 are provided in accordance with the number of shelves S placed on the tombstones, the present invention is not limited thereto. For example, only one diffusing device may be provided for the number of shelves S on which the tombs are placed. In this case, a plurality of scattering nozzles for dispersing the pesticide solution in one acidifier may be provided.

In particular, although a plurality of solenoid valves 8 are provided in accordance with the number of the change-over switches for changing the number of floats of the shelf S used for the immersion work, it is also possible to arrange a plurality of solenoid valves 8 It may be installed.

Further, the hose 9 is formed of rubber, but is not limited thereto, and may be a pipe made of metal, for example.

In particular, although the operating instrument part 21 is composed of the metal bolt 25 attached to the rod 24, the present invention is not limited thereto, and the proximity switch 22 may be any one capable of being detected by the action of a magnetic line of force.

For example, instead of a plurality of bolts 25, a plurality of protrusions are formed on the bottom surface of the groove portion 24a of the bar 24, and a roller that runs the bottom surface of the groove portion 24a of the bar 24 instead of the proximity switch 22, A switch for operating the dispersing mechanism 2 when the roller overruns the projecting portion may be provided on the rearinghorse main body M.

Particularly, the pesticide liquid to be used is not limited to the one in which the pesticide in granular form is dissolved in water, but it may be a liquid pesticide liquid. Further, the present invention is not limited to the pesticide solution for sickness relief, but may be a fluid dispersed in seedlings, for example, a liquid fertilizer.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific structure is not limited to this embodiment but includes design modifications within the scope of the present invention.

As described above, according to the invention of claim 1, since the spreading mechanism for spreading the fluid such as the pesticide, fertilizer and the like is installed in the paddy period, it is possible to distribute the fluid to the paddy field together with the paddy work, It is possible to reduce the physical burden of agricultural workers.

According to the invention of claim 2, since the dispersing mechanism performs the fluid scattering intermittently in cooperation with the planting operation by the rice planting period, it is possible to distribute a certain amount of fluid to the seedling regardless of the planting speed.

According to the invention according to claim 3, since the scattering operation control mechanism operates based on the reciprocating operation of the shelf bearing the seedlings, it is possible to distribute a desired amount of fluid to the seedlings by the scattering mechanism regardless of the planting speed It is possible.

According to the invention of claim 4, since the dispensing mechanism operates with the output as an instrument every time the proximity switch detects the approach of the actuating instrument part, it is preferable that the dispensing mechanism dispenses the desired amount of fluid It is possible.

According to the fifth aspect of the present invention, since the opening and closing of the electromagnetic valve is controlled by the scattering operation control mechanism, it is possible to intermittently disperse the fluid from the diffuser in cooperation with the seeding operation.

According to the invention of claim 6, since the fluid is scattered with the pressure in the holding container from the diffuser in the outward direction, the fluid is dispersed at a stable pressure regardless of the pulsation of the feed pump, It is possible to spread the desired position of the shelf.

According to the invention of claim 7, by oscillating the scattering nozzle, it is possible to spread the fluid over a wide range by a single scattering operation.

According to the invention as set forth in claim 8, by providing the pressure regulating valve, it is possible to prevent breakage of the holding container without excessively raising the pressure in the holding container.

In addition, since the fluid in the reservoir is agitated by the supply pump and the circulation means, it is possible to prevent the effective components of the pesticide and fertilizer contained in the fluid in the reservoir from being shifted and make the concentration of the fluid dispersed in the grains uniform .

Further, since the pressure in the holding container is made constant by the pressure pump and the pressure adjusting valve, the flow rate of the fluid dispersed from the diffuser when the solenoid valve is open is made constant, and it is possible to easily spread the desired fluid amount .
