Description

[Detailed Description of the Invention] The present invention relates to a watering machine for a seedling seeding machine that supplies water to a seedling nursery box after supplying bed soil.

The irrigation machine is configured to catch water ejected from a water supply pipe with an inclined sprinkler plate, and allow the water to fall from the sprinkler plate onto the soil floor of the seedling box.

Normally, the depth of bed soil from the top of the seedling box is approximately constant, but there are many different heights of seedling boxes, and in order to properly water the bed soil, it is necessary to change the angle of inclination of the watering board. , it is necessary to keep the distance from the bottom of the sprinkler plate to the top of the soil approximately constant.

To change the angle of inclination of the sprinkler plate, install a position-selectable pin on the frame that pivots the sprinkler plate, use this pin to hold the sprinkler plate in an inclined position, and change the position of this pin. Therefore, it has been considered to change the inclination angle of the sprinkler plate.

However, with this configuration, the angle of inclination of the sprinkler plate must be adjusted every time the type of seedling box is changed, which is very complicated, and because it is tiered, it is difficult to obtain the best inclination position. There are problems.

In view of these problems, the present invention provides a guide part on the side of the sprinkler board, and this guide part slides on the upper surface of the side wall of the seedling nursery box, thereby tilting the sprinkler plate and lowering the lower end of the sprinkler plate to the floor. The purpose of the present invention is to provide a watering machine for seedling-raising seeding equipment that maintains a constant height above the soil surface.

A feature of the present invention for achieving this purpose is that a support frame that supports a water supply pipe is placed above the seedling box transfer mechanism, and the water supplied from the water pipe is transferred to this support frame onto the soil floor of the seedling box. A water sprinkling plate is supported to be able to swing freely around a horizontal axis, and a guide portion is provided on the side of the water sprinkling plate to slide against the upper surface of the side wall of the seedling nursery box and tilt the water sprinkling plate downward in the forward direction. .

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the entire seedling-raising seeding device 1, and the seeding device 1 is roughly divided into a seedling-raising box transfer mechanism 3 that reciprocates the seedling-raising box 2 and can be switched between forward and reverse directions, and a seedling-raising box transfer mechanism 3 that supports this transfer mechanism 3. A soil-entering machine 6, a watering machine 7, and a seeding machine 8 are placed on the support frame 4 and straddle the seedling-growing box transfer path 5 of the transfer mechanism 3.

The support frame 4 has two parallel U-shaped cross-sectional frames 11 and a pair of support legs 12, and a motor section 13 of the transfer mechanism 3 is attached to one of the support legs 12.

It is driven in sync with the

When supplying bed soil, the seedling raising box 2 is moved in the direction of arrow A to supply bed soil, and then the surface of the bed soil is leveled with the rotating brush 21. When supplying covering soil, the seedling raising box 2 is moved in the direction of arrow B to cover with soil. is supplied, and at this time the rotating brush 21 is retracted upward.

The irrigation device 7 has a watering plate 24 pivotably supported below a water supply pipe 23 communicating with a water pipe, and this watering plate 24 is formed in a corrugated cross-section and spreads over the soil in the seedling box 2. The required amount of water is supplied almost uniformly.

The seeding machine 8 includes an outer frame 26 fixed to the frame 11, an inner frame 27 arranged vertically movably within the outer frame 26, a seed hopper 28, and a feed roll 29 arranged on the outer frame 26.

2 and surplus paddy discharge body 33, and the seeding roll 3
1, a rotating brush 32, a surplus paddy discharge body 33, a drive mechanism 34 for driving the feed roll 29, etc. are provided.

The seeding machine 8 is operated when the seedling raising box 2 is transferred in the direction of arrow B. Therefore, when supplying bed soil and watering, the inner frame 27 is raised upwards and the seedling roll 31, rotating brush 32 and surplus paddy are removed. The discharge body 33 is retracted upward. The pivot point of the inner frame 27 is a support shaft 35 supported by the outer frame 26.

The present invention will be explained in detail based on FIGS. 2 and 3.

A pair of support frames 38 of the irrigation machine 7 are bolted to the frame 11 and connected to each other by a connecting rod 39, and support the water supply pipe 23 and the water sprinkling plate 24.

The water supply pipe 23 is substantially parallel to the connecting rod 39, has a large number of water injection ports 23a formed therein, and is connected to the water pipe via a socket 40.

The water sprinkling plate 24 has side walls 42 on both sides of the corrugated portion 41, and the side walls 42 fit into the support rods 43 so as to be swingable. Both ends of the support rod 43 are supported through vertical elongated holes 44 formed in the support frame 38, and are prevented from slipping out by bending the ends.

Reference numeral 46 denotes bed soil placed in the seedling raising box 2, the width of the corrugated portion 41 is less than the width of the bed soil 46, and the side wall 42 is located approximately above the side wall 2a of the seedling raising box 2. A guide portion 47 is provided on the outer surface of the side wall 42 and is slidable on the upper surface 2b of the side wall 2a.

The guide portion 47 consists of a round bar 47a welded along the side wall 42, and a sliding round bar 47b welded in a T-shape to the lower end of the round bar 47a.
is a posture in which the water sprinkler plate 24 hangs down from the support rod 43,
It is located below the upper surface 2b.

Although the guide portions 47 are provided on both side walls 42 of the water spray plate 24, they may be provided on only one side, or the guide portions 47 may be formed by welding only the sliding round rods 47b to the side walls 42.

When the seedling raising box 2 after supplying bed soil is transferred into the irrigation machine 7, the tip of the seedling raising box 2 hits the sliding round bar 47b, causing the watering plate 24 to tilt downward in the forward direction. While it is in sliding contact with the upper surface 2b of the side wall, its inclined posture is maintained, and the water ejected from the injection port 23a of the water supply pipe 23 flows through the corrugated portion 41 and is supplied to the soil 46 substantially uniformly.

Since the positional relationship between the sliding round rod 47b and the lower end of the corrugated portion 41 remains unchanged, the side wall upper surface 2b and the corrugated portion 41
The relationship between the lower end 41a and the lower end 41a remains unchanged, and water can always be sprinkled on the bed soil 46 at a constant depth from the upper surface 2b in the best condition. Furthermore, even if the depth of the seedling raising box 2 varies, the depth from its top surface 2b to the surface of the soil bed 46 is constant, so watering can be performed without changing the position of the sliding round rod 47b relative to the corrugated portion 41. be able to.

Irrigation is not necessary when sowing and covering soil, so Kotoku 40
Keep it closed. No other operations are necessary, and the seedling raising box 2 passes from the seeding machine 8 to the bottom of the irrigation machine 7, and hits the sliding contact round bar 47b of the watering plate 24 in the hanging position.
Push up as shown in the imaginary line in the figure.

The elongated hole 44 is a means of avoiding when the watering board 24 is forced up, and if the watering board 24 hangs down and is swung by the seedling box 2, there will be no problem, but if the watering board 24 is slightly tilted. When the seedling box 2 moves from the inclined side and becomes jammed between the sliding round rod 47b and the roller 14, the long hole 44
The sprinkler plate 24 is configured to escape upward within the range of 1 to prevent clogging.

According to the present invention described in detail above, the watering plate is pivotally supported on the support frame so as to be able to hang down, and a guide part that can be slidably contacted with the upper surface of the side wall of the seedling raising box is provided on the side of the watering plate, so that when the seedling raising box passes, Since the sprinkler plate is configured to slope forward and downward, the lower edge of the sprinkler plate is always placed at a constant position from the top of the side wall of the seedling nursery box, and even if the depth of the seedling nursery box changes, watering in the best possible conditions.
