Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, a feeding rotary member which is driven to rotate around a vertical axis is provided below a hopper for storing powdered and granular drugs, and the drug is scattered below the feeding rotary member. While providing a rotary vane body, in the feeding rotary body, upper and lower communicating eye holes are formed at predetermined intervals around the vertical axis, and the medicine discharge port of the hopper above the eye hole and the eye hole are formed. The present invention relates to a drug spraying device in which a drop port for dropping and supplying a drug to a lower rotary blade body is provided in a state where the phases around the axis of the vertical axis are shifted from each other.

[0002]

2. Description of the Related Art Heretofore, as a chemical spraying device of this type,
For example, as disclosed in Japanese Patent Application Laid-Open No. 3-30858, the medicine storage hopper is provided with one medicine discharge port and one medicine discharge port.

[0003]

By the way, in recent years, there has been a demand for increasing the amount of the drug sprayed per unit area, and this demand can be met. It is conceivable to increase the rotation speed to increase the chance that the medicine ejection port and the eye hole are located opposite to each other.
On the contrary, when the rotation speed of the feeding rotary member is too fast, the drug is not sufficiently supplied to the eye holes, and there is a limit to the increase of the drug spray amount. Further, in order to meet the above demands, a drug storage hopper,
Although it is possible to provide a plurality of payout rotors, drop ports, and rotary vanes, the drive structure for the payout rotors and rotary vanes is structurally complex and expensive, and
Dispersing the drug with a plurality of rotary blades has a drawback in that the sprayed spots are apt to be biased and it is difficult to spray the drug evenly.

The present invention has been made in view of the above circumstances, and has a simple structure, but can increase the amount of medicine sprayed and can evenly distribute the medicine. For the purpose of providing.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, a drug spraying device according to the present invention has the above-mentioned structure and is provided with a plurality of drug discharge ports and a plurality of drop ports. It is characterized in that the plurality of drop openings are provided on the single rotary vane body. The actions and effects of this characteristic configuration are as follows.

[0006]

In other words, by providing a plurality of drug discharge ports and a plurality of drop ports respectively, it is possible to supply a drug to a plurality of eye holes corresponding to the number of drug discharge ports and drop ports with respect to one feeding rotary member. In addition, it is possible to preset the dispersion distribution of the medicine by setting the positions of the plurality of drop openings.

[0007]

As a result, the amount of medicine supplied to a single rotary vane body depends on the number of medicine discharge ports and the number of drop openings, and the medicine can be sprayed more reliably than before. The present invention has made it possible to provide a simple structure at low cost without complicating the drive structure of the rotary vane body, etc., and to spread the medicine evenly in the field scene with good workability without much trouble such as adjustment.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 6 shows a riding type rice transplanter equipped with the chemical spraying device according to the present invention. A hydraulic cylinder 2 is provided at the rear of the body 1 supported by wheels of the riding-type rice transplanter so that it can travel.
It is equipped with a seedling planting device 4 for multiple row planting, a fertilizer application device 5 and a chemical spraying device 6 for spraying a control chemical such as a herbicide through a four-link mechanism 3 which is driven up and down by.

The chemical spraying device 6 will be described in detail. As shown in FIG. 1 to FIG. 4, a hopper 7 for storing a powdery drug is provided in the upper center part in the left-right direction of the machine body, and the drug discharge ports 7a and 7b having downward openings for discharging the drug in the hopper 7 are provided in the hopper. Two are provided at the bottom of 7. In the case 10 surrounding below the lower part of the hopper 7, a rotary disk-shaped feeding rotary member 9 is provided below the drug discharge ports 7a and 7b so as to be rotationally driven around the vertical axis P. At the same time, the feeding rotor 9 has eyelets 8 that communicate vertically with each other at a constant pitch along the circumferential direction centering on the vertical axis P.
Are formed in plural. The feeding rotator 9 has a structure in which its lower surface is rotated while sliding on the bottom plate 10B of the case 10.
Two drop ports 11a, 11 for dropping the medicine downward from
b is formed. The drop openings 11a and 11b have a disk-shaped shutter 13 provided below the drop openings 11a and 11b to open and close the medicine drop path. Further below the drop ports 11a and 11b, there is provided a rotary blade body 12 which is driven to rotate about a longitudinal axis Q by a motor 14, and the medicine is dropped and supplied from the drop ports 11a and 11b. Scatter the drug with the wings. A guide case 10A that guides the chemicals scattered by the rotary vane body 12 so as to collide and be evenly distributed in the lateral direction of the machine body is connected to the case 10.

As shown in FIGS. 2 and 3, the medicine discharge port 7
Each of a and 7b is 1 with respect to the vertical axis P as a center.
They are provided with a phase shift of 80 degrees. On the other hand, each of the drop openings 11a and 11b has a distance of
It is provided with the phase shifted by 80 degrees, and is provided at the lower position in the rotational direction of the feeding rotary member 9 from the installation position of the corresponding drug ejection ports 7a, 7b. Therefore, the medicines ejected from both medicine ejection openings 7a and 7b are supplied to the eye holes 8 at two locations almost at the same time, and at the same time fall from the two drop openings 11a and 11b to the rotary vane body 12. Will be supplied.

Next, the shutter 13 will be briefly described. The shutter 13 is provided so that it can be manually rotated around the vertical axis P from the outside of the case 10 and is held at a predetermined rotation position. In order to be able to switch between a state in which only one of the 11b is opened downward and a state in which both are opened, the elongated holes 13 having a phase shift as shown in FIG.
a and 13b are formed.

Next, the fertilizer storage hopper 1 of the fertilizer application device 5
5 will be briefly described. As shown in FIG. 5, the fertilizer storage hopper 15 is provided with a first hopper 15A for storing fertilizer for deep-layer fertilization at the center for each planting article, and side-row fertilizer application for left and right of the first hopper 15A. The second hoppers 15B and 15B for storing the fertilizer are continuously connected. First
At the upper edge of the partition wall between the hopper 15A and the second hoppers 15B, 15B, a swing lid 16, which can close the upper opening of each of the second hoppers 15B, 15B or the upper opening of the first hopper 15A, Resin support parts 17, 17 for pivotally supporting 16
Is provided. Therefore, when the fertilizer is supplied to the first hopper 15A, the rocking lids 16 and 16 are used to feed the second hoppers 15B and 1B.
5B, the upper opening of each of the second hoppers 15B, 1B is closed.
When supplying fertilizer to 5B, the rocking lids 16 and 16 are used for the first
By closing the upper opening of the hopper 15A, it is possible to prevent different types of fertilizer from entering.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
