Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is for cultivating vegetables and the like, laying a multi-sheet, and seeds and fertilizers or seeds and pesticides at the center of the opening formed in the multi-sheet It is related to the configuration for distributing.

(B) Conventional Technology Conventionally, a technology for simultaneously performing fertilization and drug application via an intermittent opening chute has been known. For example, it is as disclosed in JP-A-59-151806.

Further, as a working machine to be mounted on a tractor or a management machine, a device for simultaneously performing fertilizer application and drug application is known.

For example, Japanese Utility Model Publication No. 60-67007 and Japanese Utility Model Publication No. 57-14011 are available.

(C) Problems to be Solved by the Invention In the technology disclosed in Japanese Patent Laid-Open No. 59-151806, which is the conventional technology, an opening / closing portion is configured by a shutter and a sensor, and the sensor and the shutter are integrated. It has been transformed.

Therefore, the stroke in which the sensor detects the opening portion and turns is the same as the opening / closing stroke and opening / closing stroke of the shutter both in terms of direction and stroke.

However, the surface of the mulch film does not always form a constant surface, and the soil surface below the mulch film also moves up and down, so that the sensor may not fully descend or may not sufficiently rise.

In such a case, the shutter 46 may not be opened or may not be closed.

Since the present invention opens and closes the rotating portion of the shutter through the U-shaped rod and the shutter pipe, the vertical direction and stroke of the U-shaped rod can be changed at the rotating portion of the shutter for reliable opening and closing. It was configured to do so.

(D) Means for Solving the Problems The object of the present invention is as described above, and the configuration for achieving the object will be described below.

The medicine / fertilizer tank 12 and the fertilizer or pesticide feeding device, and the seeding tank 13 and the seed feeding device are arranged side by side, and a merging chute 1 is provided at the lower part of both feeding devices. , The multi-sheet F is dropped into the aperture Fa, the intermittent opening chute fixes the U-shaped rod support plate 7 around the chute 6, and
The shutter rotation part 2 is pivotally supported by the pivot support part 2a around the lower end opening of the chute 6 below the rod supporting plate 7, and the shutter fixing part 3 is fixed around the lower end opening of the chute 6 as well. Then, when the rotating portion 2 rotates, the space between the rotating portion 2 and the fixed portion 3 is opened, and when the shutter pipe 4 rises, the rotating portion 2 rotates and closes in close contact with the fixed portion 3. A shutter is constituted, a U-shaped rod 5 is supported by the U-shaped rod support plate 7 so as to be movable up and down, and a shutter pipe 4 is fixedly mounted on the U-shaped rod 5. When the U-shaped rod 5 moves on the upper surface of the multi-sheet F, the rotating portion 2 of the shutter presses the fixed portion 3 of the shutter in the closing direction, so that the U-shaped rod 5 contacts. By passing through the opening Fa, the U-shaped rod 5 and the shutter pipe 4 descend, The rotating part 2 of the batter is constructed so as to rotate around the pivot 2a.

(E) Embodiment The purpose and construction of the present invention are as described above. Next, the construction of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a perspective view of a sowing / fertilizing / medicating machine of the present invention attached to a management machine, FIG. 2 is a perspective view of a disassembled state of a confluent chute 1 and a feeding device, and FIG. 3 is a tank and feeding. The device, the merge chute 1, the guide pipe and the intermittent opening chute are rear sectional views, FIG. 4 is a side sectional view of the same, FIG. 5 is a rear enlarged sectional view of the feeding device and the merge chute 1, and FIG. A side view of the intermittent opening chute and the portion of the multi-seat F, FIG. 7 is a rear view of the same, FIG. 8 is a side sectional view of the state in which the intermittent opening chute is open, and FIG. 9 is a multi-seat F.
A plan view showing a state in which seeds and pesticides are sprayed at the central position in the opening Fa of FIG. 10, FIG. 10 is a plan view showing a state in which seeds and pesticides are sprayed in a non-centered state. .

FIG. 1 shows a state in which the management machine is equipped with the seeding / fertilizing / medicated machine of the present invention.

Multi-sheet F is laid on the soil in which the plowing claws have been cultivated or agitated, and the soil is placed on the hem so as not to be blown off by the wind. The pesticide fed from the medicine / fertilizer tank 12 and the seed fed from the seeding tank 13 are dropped to the center of the opening Fa as far as possible in the center.

The feeding device under the medicine / fertilizer tank 12 / seeding tank 13
The feeding cases 19 and 20, the feeding rolls 14 and 15, and the brushes 16 and 17 that are in close contact with the feeding rolls.
The feeding rolls 14 and 15 are simultaneously driven by the feeding drive shaft 21 of the book.

And conventionally, the pesticide and the seeds fed from the feeding rolls 14, 15 have been conveyed to the soil surface through separate guide pipes, but in the present invention, the feeding rolls 14, 15 The confluent chute 1 is provided in the space below to concentrate the pesticide b and the seed a on one guide pipe 18.

The lower end of the guide pipe 18 communicates with the intermittent opening chute.

The intermittent opening chute includes a chute 6 and a U-shaped rod support plate 7
The pivotal support portion 2a of the rotating portion 2 of the shutter and the fixed portion 3 of the shutter are fixed.

The U-shaped rod 5 is supported by the U-shaped rod support plate 7 at the front portion via a spring 24, and the shutter pipe 4 is integrated with the U-shaped rod 5 and moves up and down.

Since the U-shaped rod 5 is positioned in contact with the top of the multi-sheet F, the multi-sheet F is pulled out and covered on the ridges, and the U-shaped rod 5 is placed on the top of the multi-sheet F. When moving, when coming over the part of the opening Fa, U
The character rod 5 falls into the opening Fa, whereby the shutter pipe 4 fixedly mounted on the U-shaped lever 5 moves up and down, and the rotary portion 2 of the shutter pivotally opens around the pivotal support portion 2a. .

The pesticide and the seeds have dropped from the confluent chute 1 through the guide pipe 18 and the chute 6 and onto the closed space of the shutter rotating portion 2 and the shutter fixing portion 3, so that the shutter rotating portion 2 While opening, both the pesticide and the seed are dropped on the center of the opening Fa.

The multi-sheet F is maintained in a stretched state by the front guide roller 22a and the rear guide roller 22b.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, the fixed part 3 of the shutter and the rotating part 2 of the shutter.
The shutter configured by is opened and closed by a shutter pipe 4 that abuts from below, and the shutter pipe 4
Since it is configured to move up and down by the rod 5, the opening and closing of the shutter portion is surely performed depending on the presence or absence of the opening portion Fa of the multi-sheet F, and between the rotating portion 2 of the shutter and the fixing portion 3 of the shutter. The possibility that fertilizer or seeds would be caught was low, and it was possible to prevent the fertilizer or seeds from running away when the fertilizer or seeds were caught in the portion.

Secondly, the vertical movement of the U-shaped rod 5 and the shutter pipe 4 due to the presence or absence of the opening Fa in the multi-seat F is converted into the rotational force of the rotating portion 2 of the shutter pivotally supported by the pivot 2a to open and close. As a result, the operation of the opening / closing part can be performed smoothly.
