2. Description of the Related Art Hitherto, there has been known a box application agent which sprays osmotic granules onto a nursery box immediately before rice planting to control pests that occur shortly after transplantation. The box application agent is capable of controlling most of the main pathogens occurring before heading by a single chemical treatment. Recently, long-lasting box application agents that can suppress the occurrence of insect pests, leaf potatoes, and sheath blight that occur after the middle stage of rice cultivation have appeared. However, since it is very troublesome to carefully spray a predetermined amount of the medicine to the nursery box by hand spraying just before the busy rice planting, it is very cumbersome to use a power sprayer to process a large amount of the medicine or hand spraying. Even if it is rough work, even spraying may be regarded as a problem.

[0003]

In the above-described chemical spraying operation, the operation of spraying a chemical to a nursery box immediately before rice transplanting is performed manually. However, the present invention provides a rice transplanter equipped with a drug applicator and rice transplanting.

However, in the case where the dispensing machine is mounted on the seedling mounting table of the rice transplanter, in order to avoid interference with members such as a seedling mat holding mechanism at the lower end of the seedling mounting table near the seedling outlet, The dispensing machine must be located at a location upwards away from the exit. That is, since the place where the medicine is sprayed is located above the seedling removal outlet, there is a portion where the medicine cannot be sprayed by the dispensing machine on the first seedling mat, and there is a possibility that uneven spraying may occur. However, the pests generated here may be an important source of infection. Therefore, in the construction of a working machine capable of carrying out medicine application simultaneously with rice planting by mounting a medicine applying machine on the rice planting machine, in particular, a rice planting machine capable of applying medicine evenly on the first seedling mat at the start of planting work. A configuration of a vertical feed mechanism is provided.

A description will be given of the dispensing machine C disposed above the seedling table 16 of the rice transplanter A for performing the above-mentioned medicine concurrently with the rice transplanting. As shown in FIGS. 2 to 7, the dispensing machine C includes a delivery unit 41 and a medicine hopper 42 mounted on the delivery unit 41.
The driving mechanism of the dispensing machine 40 is a cover 80
It is decorated inside. Support arms 43 are provided upright on the rear portions of the seedling mounting ribs 60, and a support frame 44 bridges the upper ends of the support arms 43. The feeding portion 41 is fixed to the support frame 44 by bolting.
The same number (6 in this embodiment, that is, 6) of drug application machines 40, 40... As many as the number of riding rice transplanters A are disposed above the seedling mounting table 16.

As shown in FIG. 4, a drug delivery roll 45 is provided in the delivery section 41, and is pivotally supported by a casing. The medicine hopper 42 and the feeding section 41 are connected to each other so that the medicine drops to the medicine feeding roll 45 via the medicine supply pipe 46 inside the feeding section 41.
The drug is in a granular form.

On the outer peripheral surface of the medicine feeding roll 45, FIG.
As shown in the figure, a number of depressions 45a are provided. Depression 4
5a is configured so that a certain amount of medicine can be dropped into the depression 45a, and the medicine stored in the medicine hopper 42 falls into the depression 45a. Further, the lower end of the medicine supply pipe 46 and the outer peripheral surface of the medicine feeding roll 45 are configured to be substantially in contact with each other, so that the medicine does not fall from this gap. The medicine feeding roll 45 is configured to rotate by a mechanism described later, but when the medicine feeding roll 45 is stopped, the medicine does not drop from the feeding section 41. When the medicine feeding roll 45 rotates, the medicine that has fallen into the depression 45 a and overflows from the outer peripheral surface of the medicine feeding roll 45 is regulated by the lower end of the medicine supply pipe 46. At this time, the overflowing medicine is retained inside the medicine supply pipe 46 and falls off from the depression 45a.
Therefore, only the medicine that has fallen into the depression 45a and is inside the outer peripheral surface of the medicine feeding roll 45 is fed to the feeding section 41.
It falls more and more sequentially.

At the lower end of the medicine supply pipe 46, a guide 46a is provided along the outer peripheral surface of the medicine feeding roll 45.
The guide 46a is provided only along the rotation direction of the medicine feeding roll 45. The medicine held in the depression 45a is restricted from falling by the guide 46a during the rotation of the medicine feeding roll 45. The medicine held in the depression 45 drops from the feeding section 41 only when the depression 45a reaches a position not covered by the guide 46a by the rotation of the medicine feeding roll 45. That is, by providing the guide 46a, the medicine is regulated so as to drop directly below the feeding section 41, and the diffusion of the medicine in the front-rear direction is prevented.

The medicine delivery roll 45 is provided with a rotary brush 66 in which a brush is implanted on a rotating shaft 66a so as to be in contact with the delivery roll 45. As shown in FIG. 6, the brush 66 has a rotation axis 66a parallel to the medicine feeding roll 45 and a rotation axis 49 of the medicine feeding roll 45.
The horizontal height is the same as or below, and it is detachably attached to the outer frame of the spraying part 41 below. When the medicine feeding roll 45 rotates, the brush 66, which is in contact with the medicine feeding roll 45, rotates so as to be caught in the depression 45a of the medicine feeding roll 45, and the medicine clogged in the depression 45a of the medicine feeding roll. Is scraping off.
That is, clogging can be prevented by attaching the brush 66, unevenness in the amount of applied medicine can be reduced, and delivery of the medicine can be stabilized with a simple mechanism. Brush 6
6 is rotatable, so that the brush 66 is also rotated by the rotation of the medicine feeding roll 45, and the depression 4
5a is rotated in a direction in which the tip of the brush 66 scrapes out the medicine clogged therein. Since the brush 66 rotates but does not require any special power, and the brush does not rotate more than necessary, the brush does not wear more than necessary, and in addition to the brush which is fixed and does not rotate, The rotating brush is less likely to have a habit. In addition, since the brush is configured to be detachable by the fixing member 65, it is convenient for cleaning the brush and replacing the brush with a new one when the brush is worn.

The brush 66 does not necessarily have to be a rotating body. The brush 66 may be attached to the tip of a bracket and brought into contact with the feeding roll 45, as shown at 66b in FIG. . Also in this case, the brush 66b is provided detachably, and is configured so that the brush 66b can be easily replaced when the brush 66b is worn or deformed.

A dispensing cover 53 is attached to the feeding section 41. The left and right width of the medicine applying cover 53 is set to be longer than the left and right width of the seedling mat 51 so as to act over the width of the seedling mat 51. As shown in FIG. 2, the lower end of the drug application cover 53 is formed in an arch shape, and the contact position with the seedling is higher at the center of the lower end. This is because, when the lower end of the drug application cover is formed on a straight line, the division of the seedlings is delayed at the center of the seedling mat, and the division has a shape that bulges forward, so that the division formed by the drug application cover is linear. This is a shape for making the arrival rate of the drug on the seedling mat 51 uniform over the entire width of the seedling mat 51. Therefore, the seedling mat 51 placed on the seedling mounting base plate 62 is sent to the rear end of the seedling mounting base 16 by the seedling feeding belt 63, but is dropped on the seedling mat 51 in the process. The leaves of the seedlings to be provided are pressed down by the drug application cover 53 to form a division. Therefore, the medicine quantitatively discharged from the feeding section 41 falls in the air or the medicine cover 53.
, And reaches the division of the seedling mat 51 formed by the medicine applying cover 53, is absorbed from the roots, and exerts its effect.

The above-mentioned dispensing machine C feeds the granular medicine to the feeding section 4.
It is of the type that is dropped quantitatively from above by the first feeding roll 45, but as shown below, the agent is sprayed to the vicinity of the root of the seedling grown on the seedling mat with the assistance of a liquid such as water. There may be. By spraying the medicine together with the liquid, the medicine can be smoothly dropped onto the seedling mat and sprayed reliably. Furthermore, it is possible to mix and spray other liquids such as insect repellents to liquids, to spray with diluted liquid using condensed drugs, or to spray solid and liquid drugs simultaneously. Becomes

As shown in FIG. 8, the medicine hopper 42 of the dispensing machine is internally divided into two spaces by a shielding plate 58, one of which is a medicine tank 56 for storing a medicine, and the other is for storing a liquid such as water. A liquid tank 57 to be filled.

In the same manner as when the above-mentioned assist by water is not performed, a medicine dispensing roll 45 for dispersing a granular medicine quantitatively is provided inside the dispensing section 41, and is pivotally supported by a casing. .

The liquid to be mixed with the medicine in the dispensing machine C is supplied from the liquid tank 57 of the medicine hopper 42 to the drip nozzle 77 through the tube 67. A drain port 69 from the liquid tank 57 is provided outside the medicine hopper 42, and the tube 6 is connected to the drain port 69 via a packing 69a.
7 is attached. That is, the tube 67 is replaceable and detachable so as to be convenient for maintenance such as cleaning. Tube 67 is drug hopper 4
2, enters the feeding section 41, and the pressure roller 68 fixed to the rotating shaft 49 of the medicine feeding roll 45 of the feeding section 41 rotates to press the tube 67 to send out the liquid. That is, a predetermined amount of liquid is sent out by a tubing pump having a simple structure using a power for spraying a medicine without providing another power source.

The distal end of the tube 67 for transporting the liquid quantitatively sent out by the feeding section 41 enters the dripping nozzle 77. Therefore, the medicine that has quantitatively dropped from the feeding section 41 in the dropping nozzle 77 as described above is assisted by the liquid that is also quantitatively supplied, and drops from the dropping nozzle 77, and the chemical is dropped. Spread to 51. In addition, it is also possible to disperse a plurality of kinds of medicines simultaneously by dissolving another medicine in the liquid, or to spray only a liquid diluted with the medicine. When it is desired to spray only a solid medicine, the liquid tank 57 is used. If more liquid is removed or the tube 67 is removed from the tubing pump, no liquid is supplied and only solids can be sprayed.

Here, the vertical feeding mechanism E of the seedling mat 51 of the seedling mounting table 16 and the drive configuration of the dispensing machine C interlocked with this will be described.

A planting center case 20 is rotatably mounted on a pivot boss formed on the lower link 26 of the link mechanism 27 shown in FIG. 1, and the planting center case 20 has a power take-off shaft. Power is transmitted from the traveling unit 1 side via 23. Then, the power transmitted to the planting center case 20 is configured to be transmitted to the above-described lateral feed mechanism, vertical feed mechanism E, and planting mechanism D of the seedling mounting table 16.

The seedling mounting table 16 is provided with a vertical feeding mechanism E for vertically feeding the seedling mat 51 by a predetermined amount toward the planting mechanism D at a lateral sliding width end.
