Description

Detailed Description of the Invention

[0001]

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

[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 rice transplanter equipped with a chemical spraying device.

[0002]

2. Description of the Related Art Various types of riding type rice transplanters equipped with a chemical spraying device have been proposed. The devices for spraying chemicals in a field are roughly classified into the following [1] and [2].
The form described in (1) is conventionally 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. Moreover, with such a structure that sprays already planted seedlings on the lateral sides of the aircraft, it will not be possible to spray the seedlings after the traveling aircraft has passed in the final process of planting seedlings, so artificial post-working There is also a problem in that

It is also possible to use the power from the seedling planting device to drive the drug spraying device. But,
When the seedling planting device is configured for multiple articles,
When using power from a transmission system that drives one of the planting strips, such as a planting arm that is relatively easy to take out power, the planting system is changed by a mechanism for changing the number of planting strips called each clutch. There is room for improvement because the chemical spraying device cannot be driven when the seedling planting work is performed without driving.

An object of the present invention is to suppress the increase of the vertical height of the drug spraying device to reduce the size of the whole, and to spread the drug from the spraying device as widely and as uniformly as possible,
In addition, the rice seeder plant is rationally configured to operate by the power from the seedling planting device and to reliably operate the chemical spraying device regardless of how the clutch for changing the number of planting rows is operated.

[0009]

A feature of the present invention is that a chemical spraying device is provided at a position rearward of a seedling planting device connected to the rear of a riding type traveling body and the seedling planting device is used for a plurality of articles. And at least two transmission systems for the seedling planting device are formed, and a clutch for independently driving and stopping the planting strips on both the left and right sides is provided. A rotating body that scatters the medicine supplied from the feeding mechanism along with the rotation, and a diffusion guide body that scatters the medicine scattered by this rotating body to a seedling planting width and sends it to the field scene. Furthermore, it has two independent transmission mechanisms that drive the feeding mechanism by the power from the drive systems of the planting strips on both the left and right sides of the seedling planting device, and the action and effect are as follows. Is the street.

[0010]

According to the above feature, after the medicine delivered from the feeding mechanism is splashed by the rotating body, the diffusion guide action of the diffusion guide member makes it uniform in the seedling planting width direction in the field scene. When it is sent in this way, the drug is forcibly scattered by the rotating body, so that the dispersion angle can be easily expanded, and furthermore, the drug that moves at a relatively high speed is guided, and Since the particles are diffused, the spraying can be made directional, and a desired spraying amount can be secured even at a position separated from the rotating body.

Further, since this diffusing device is arranged further rearward of the seedling planting device at the rear of the riding type traveling, the spraying direction is set to the field scene at a position greatly separated from the control section on which the operator is riding. Controllable drug delivery. Therefore, it is easy to work in a good working environment by suppressing the scattering of the medicine near the control section as much as possible.

Further, while the sprayed chemicals are sprayed to the seedlings in the machine running row, the spraying device is located behind the seedling planting device in the traveling direction, so that the seedling planting device The chemicals are sprayed in a field scene where there is a seedling planted in. Therefore, it is possible to avoid a situation in which the drug adheres to the root of the seedling before planting.

Further, since two transmission mechanisms are provided between the drive systems of the left and right planting strips and the drug spraying device, the drug spraying device is powered even if any of the strip clutches is disengaged. It becomes possible to convey. In other words, when operating with the number of planting rows changed, the planting operation of a predetermined number of rows is stopped from one end side in the left-right direction of the seedling planting device, and the other side is always activated. Even during such an operation, the medicine spraying device can be operated by the power from the side where it is operated.

[0014]

Therefore, the medicine is spread widely and evenly in the lateral direction after traveling of the machine body, and the medicine spraying apparatus is prevented from becoming large in size, and the working environment is good. The rice transplanter was reasonably constructed so that it could be sprayed without causing the chemicals to adhere, and that even if the clutch for changing the number of planting lines was disengaged, it was operated by the power from the seedling planting device.
