Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a chemical spraying device for a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, as a device for spraying a drug to a field, there are those shown in JP-B-54-33852 and JP-B-55-6248, and in each reference, the drug is supplied to the field. The path to do so is formed in a fan shape so that it expands toward the side closer to the field, and a wall body that disperses the drug is arranged in this path, and powdery and granular drugs will fall on the wall during the fall of this path. It is configured so as to be uniformly dispersed by collision with the body or guiding action of the wall body.

[0003]

However, in the spraying device of the above-mentioned reference, since the structure is to disperse in the horizontal direction by utilizing the drop motion of the medicine by its own weight, the angle of dispersion of the medicine can be increased. If it is difficult to spread the medicine widely, there is room for improvement because the vertical size of the spraying device becomes large. Therefore, it is conceivable that the drug is supplied to the rotating body and the drug is splashed by the rotating body to diffuse the drug, but in the structure in which the drug is diffused only by the rotating body, the drug is closer to the rotating body. Since it is sent out in large quantities, not only is it difficult to spread uniformly, but it is also difficult to give directionality to the spraying because the area where the drug is sprayed is formed in a circular shape, and as a spraying device for rice transplanters, There is room for improvement. Further, considering the chemical spraying device provided in the rice transplanter, in the chemical spraying device provided in the rice transplanter as described above, only during the seedling planting work, that is, the machine is run and the seedling planting device is driven. Since the spraying of the chemicals is performed only in the state where the seedlings are planted, for example, when a dedicated switch for stopping the operation of the chemical spraying device is provided, it is necessary to operate the switch each time the seedling planting work is started or interrupted. There is room for improvement not only because it is necessary but also because the operator forgets the operation. It is also possible to use the power from the seedling planting device to drive the drug spraying device. However, in the case where the seedling planting device is configured for a plurality of rows, if the power from the transmission system that drives one of the planting rows is used, such as a planting arm from which power can be extracted relatively easily, There is room for improvement because the mechanism for changing the number of rows to be planted, called a row clutch, may not be able to drive the chemical spraying device when performing seedling planting work without driving the planting system. Further, the drug spraying device needs to adjust the spraying amount, and in order to carry out this adjustment, it may be possible to change the dispensing amount by, for example, replacing the dispensing member for feeding the drug to the drug dispersing system. However, with this configuration, it takes too much time to adjust, and there is room for improvement. An object of the present invention is to firstly disperse a drug as widely as possible and evenly as much as possible, and to configure a spraying device that can be reasonably equipped in a rice transplanter, and secondly, a spraying device that operates smoothly during seedling planting work. The device is composed, thirdly, it is operated by the power from the seedling planting device and the spraying device which is operated regardless of how each row clutch is operated, and fourthly, the spraying amount is controlled by the simplest operation possible. The point is to reasonably configure the spraying device for adjustment.

[0004]

The features of the present invention are, firstly, a rotating body that scatters a medicine supplied from a feeding mechanism by its rotational force, and a medicine scattered by this rotating body in a predetermined direction. Secondly, it has a guide member for guiding and a diffusing member for diffusing the sprayed medicine in the seedling planting width at the guide direction position of this guiding member and sending it to the field scene. The seedling planting device has an operation system that is operated in association with the drive of the planting device and that operates the actuator that drives the rotating body in a manner not associated with the drive of the planting device. For at least two rows, and at least two transmission systems for the seedling planting device are formed to provide a clutch for independently driving and stopping the planting rows on both the left and right sides, and the feeding mechanism. Drive the planting strips on the left and right sides of the seedling planting device. The point is that it has two independent transmission mechanisms that are powered by each, and fourthly, the feeding mechanism is configured as a variable capacity type that increases or decreases the supply amount by changing the operation stroke, and this feeding mechanism has seedlings. The transmission mechanism for transmitting the reciprocating actuation force from the planting device is provided, and the adjusting mechanism for changing the reciprocating operation stroke is interposed in the transmission mechanism. The action and effect are as follows. .

[Operation] When the above features are configured as shown in FIGS. 2 and 4, for example, the medicine delivered from the delivery mechanism 18 is splashed by the rotating body 19 and then guided in a predetermined direction by the guide member 19. At the same time, it is sent to the field scene in a state where it is made uniform by the diffusion member 21. That is, since the medicine is forcibly scattered by the rotating body 19, the dispersion angle can be easily expanded, and moreover, the medicine moving at a relatively high speed is guided and diffused, so that the directionality of the dispersion can be improved. In addition to the holding, the desired amount of spraying can be secured even at a position separated from the rotating body 19.
Further, since the feeding mechanism 18 is linked to the drive of the seedling planting device A and the rotating body 19 is not linked, as shown in FIG.
It is also possible to operate the feeding mechanism 18 after the operation of, and by setting the sequence of the operations in this way,
It operates reliably during seedling planting work, and in this setting, the medicine is supplied to the rotating body 19 in a rotating state, so that necessary diffusion can be performed even in the initial stage of operation. Further, as shown in FIG. 3, two transmission mechanisms 25, 2 are provided between the drive system of the planting strips on the left and right sides and the drug spraying device.
Since 5 is provided, it is possible to transmit power to the drug spraying device C regardless of which of the thread clutches E is disengaged. Further, since the adjusting means D is provided as shown in FIG. 5, the spraying amount can be adjusted by an operation of adjusting the slack amount of the wire 25 as shown in FIG.

[Effects] Therefore, it is possible to disperse the medicine widely and evenly, and to equip the rice transplanter without difficulty, so that the seedlings can be operated reliably and comfortably at the time of planting work, and the respective clutches can be disengaged. The spraying device was rationally configured to operate with the power from the seedling planting device and to adjust the spraying amount with a relatively simple operation.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical spraying device for rice transplanters.

[0002]

2. Description of the Related Art Various types of chemical spraying devices have been proposed, but as a device for spraying chemicals in a field, the devices described in the following [1] and [2] are generally used. Better known.

[1] Self-weight drop type A path for supplying a drug to a field is formed in a fan shape so as to expand toward the field side, and a wall body for dispersing the drug is arranged in this path to form a powder. , The granular medicine is configured to be uniformly dispersed by colliding with the wall body or guiding action of the wall body while falling through this path (for example, Japanese Utility Model Publication No. 54-33852, or See Japanese Official Publication No. 55-6248).

[2] Side blow-off type A plurality of rows of planted seedling rows located laterally of the traveling machine body are provided with a chemical discharge nozzle toward the lateral outside of the machine body at one lateral side of the traveling machine body. A method in which a drug is sprayed and sprayed toward the target (for example, Japanese Utility Model Publication No. 50-64514 or Japanese Patent Application Laid-Open No. 56
-See 144034 publication).

[0005]

However, in the spraying device of the conventional structure described in the former [1], the drug is dispersed because it is a structure for horizontally dispersing by utilizing the drop motion of the drug by its own weight. It becomes difficult to increase the angle, and when it is attempted to spread the medicine widely, there is a problem that the vertical size of the spraying device becomes large and the size of the entire device increases.

Further, in the case of the conventional structure described in the latter [2], since the medicine is given a lateral lateral blowing motion, the medicine is sprayed and supplied to the existing seedlings at the lateral lateral position of the traveling machine body.
There is a problem that a larger amount of the medicine is sent out in the vicinity of the blowing nozzle, and it is difficult to uniformly diffuse the medicine in the lateral direction of the traveling direction.

Further, in the chemical spraying device of the rice transplanter, the chemical spraying is started at the same time when the seedling planting is started, and the spraying of the chemical is finished at the same time when the seedling planting is finished, in cooperation with the seedling planting operation. The point that the feeding operation improves the operability, and
It is desirable from the viewpoint of not wasteful consumption of the drug, and a device for easily performing this linkage is also desired.

The object of the present invention is to suppress the increase in vertical height to reduce the overall size, and to make the drug as wide as possible,
The point is to reasonably configure a rice transplanter equipped with a chemical spraying device that disperses as uniformly as possible and that can spray a proper amount of chemical with the start of seedling planting work.

[0009]

A feature of the present invention is to provide a delivery mechanism for delivering a predetermined amount of medicine stored in a hopper,
The seedling planting device is provided with a drug spraying device consisting of a rotating body that scatters the drug dispensed by the payout mechanism with a rotational force, and the payout mechanism has a large number of through holes for receiving the drug from the hopper, And, a one-way clutch composed of a disk-shaped member that rotates around the axis, and a one-way clutch that rotates the disk-shaped member around the axis in one direction by the reciprocating operation force transmitted from the seedling planting device. It is located at a lower position of, and its action and effect are as follows.

[0010]

According to the above feature, the medicine delivered from the feeding mechanism is splashed and diffused by the rotating body which is rotationally driven around the axis, and the dispersion angle is expanded to make the seedlings uniform in the width direction. As a result of being sent to the field scene in the illustrated state, it becomes possible to secure a desired spraying amount even at a position separated from the rotating body.

Further, in the medicine spraying apparatus, the reciprocating operation force transmitted from the seedling planting apparatus is converted into a rotational operation by a one-way clutch to transmit the disk-shaped member, and the disk-shaped member is rotated to dispense the medicine. Therefore, there is no time delay based on the operation of the seedling planting device when starting or stopping the feeding of the medicine,
Moreover, since reciprocating actuating force is used as a drive mode, for example, in comparison with a device that requires a complicated transmission system such as a bearing or a joint in order to transmit the rotational power from the seedling planting device to the feeding mechanism. Thus, a transmission system having a simple structure such as a wire or a rod is sufficient, and the structure can be simplified and the cost can be reduced. Further, since the one-way clutch is arranged below the disc-shaped member, a transmission system capable of directly transmitting power from the one-way clutch to the disc-shaped member can be easily formed, and the transmission system can be further simplified and the device can be improved. Enables downsizing.

[0012]

As a result, it is possible to reduce the size of the entire body while spraying a wide range of medicines in a state where the medicine is made uniform in the lateral direction of the machine body, and at the same time, the structure is small, simple and inexpensive, and has good operability. The rice sprayer's chemical spraying device that does not waste chemicals was reasonably constructed.
