Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a corner soil pressing device in a seedling nursery box.

(Prior art) In the conventionally known Japanese Utility Model Application Publication No. 60-190244, a pressure roll is provided above a transfer table that transversely transports a seedling growing box filled with bed soil, and a pressure roll is provided on the front side of the pressure roll. It is described that a corner presser is provided which moves up and down integrally with the roll and presses the inner corner of the front wall of the seedling raising box.

(Problems to be Solved by the Invention) The above-mentioned known device has a problem in that it is a pressing body that moves up and down integrally with the pressing roll.

In other words, the pressure roll is used to push and flatten the large granular soil lumps (3 tags to 7 m+s) protruding from the top surface of the bed soil supplied to the seedling nursery box, so all the grains are 2.
The following very fine bed soil does not require compaction, and even in the case of such bed soil, there is a problem that the mound at the corner inside the front wall of the seedling nursery box cannot be flattened unless it is compacted.

In particular, in the case of a seeding device for row seeding, since the grooves are formed by a row roll after the bed soil is supplied, there is no compaction by a pressure roll, so the conventional one cannot be used, and instead of the pressure roll, a row roll is used. Another issue is that a dedicated corner floor soil pressing device is required.

(Object of the Invention) Therefore, the present invention flattens the embankment at the corner inside the front wall of the seedling nursery box, regardless of the compaction of the bed soil, and flattens the bed soil at the corner of both the withdrawal sowing device and the row sowing device. It can also be used as a pressing device and can be pressed.

(Means for Solving the Problems) Therefore, the present invention has a transfer table 1 for transversely transporting seedling growing boxes 2, and a bed soil supply device 5 provided above the transfer table 1, in which the bed soil is A rotary brush 8 for leveling the bed soil is provided on the seedling box transfer side of the supply device R5, and the rotary brush 8
Next, there is provided a corner bed soil pressing device in a seedling raising box, which is provided with a pressing body 13 having a pressing part 14 that presses the inner corner A of the front wall 16 of the seedling raising box 2.

A one-rotation type brush 8 is provided on the transfer table l located on the lower side in the transfer direction of the bed soil supply device 5. Although not shown in the drawing, the zero-rotation type brush 8 has shafts at the tips of a pair of left and right arms. The base of the arm is rotatably attached to the transfer table l, and the upper surface of the floor ±9 inside the seedling box z passing below is leveled.

A corner pressing device 10 is provided on the lower side of the rotary brush 8 to press soil that cannot be removed by the rotary brush 8 at the inner corner A of the front wall 16 of the seedling raising box 2.

The bases of a pair of left and right rotating arms 1111 are rotatably attached to the transfer table l (Fig. 2). Reference numeral 12 is a connecting rod that connects the ends of the rotating arms 11. It is bent into a b-shape and formed integrally with the rotating arm 11.11 (it may be formed separately).

The connecting rod □ is provided with a left-right corner pressing body 13 that moves vertically in an arc shape as the rotating arm 11.11 rotates.

The corner presser 13 has a modified square tube shape in cross section, and the inner surface of the square tube is fixed to the connecting rod.

The lower front side of the corner pressing body 13 forms a substantially horizontal pressing part 14 over the entire width in the left and right direction, and the rear edge of the pressing part 14 has an inclined guide that slopes higher toward the rear. The surfaces 15 are arranged in series (FIG. 9).

The inclined guide surface 15 is formed at an inclined angle such that when the upper edge of the front wall 16 of the seedling raising box 2 comes into contact with it and moves forward, the entire pressing part 14 is moved once.

The connecting rod 1 is attached to the base side of the rotating arm 11.11.
Attach the lever 17 which urges the pressing portion 14 to rotate downward at all times via the screw 17 (FIG. 2).

The pressing portion 14 and the inclined guide surface 15 are arranged inside the left and right side walls 13 so that when the seedling raising box 2 passes below, the spring 17 pushes the corner A of the seedling raising box 2 downward. It is formed with a left and right width slightly narrower than the width.

Horizontal plate-shaped mounting plates 19.19 are fixed to both left and right ends of the outer connecting rod 12 to which the corner presser 13 is fixed, and the mounting plates 19.19 have vertical screw shafts. Canada, 20
Screw the upper and lower intermediate parts of the

Adjustment dials 21 and 21 are fixed to the upper ends of the screw shafts 20 and 4, and pressing depth adjustment plates 21 and 21 are provided below the screw shafts 20 and 4.

Suppression depth sl! The base of lWJ board Shio and Shio is the transfer table 1.
It is pivoted on the upper surface by a vertical shaft n so as to be rotatable in the left and right direction, and a pressing depth adjustment plate n is provided on the tip side of the pressing depth adjusting plate η.
, a stepped portion 24 higher than the upper surface of the tide is provided.

The screw shaft 20, the adjustment dial 21. and the pressing depth adjusting plate η form a pressing depth adjusting device ii.

The pressing depth adjusting device 3 lifts the corner pressing body 13 and once R the lower end on the screw shaft side is placed on the stepped portion 24 of the pressing depth adjusting plate.
In this state, rotate the adjustment dial 21 (Figs. 3 and 4) so that the lower surface of the pressing part 14 comes into close contact with the upper surface of the front wall 16 of the seedling raising box 2, and then turn the pressing depth adjustment plate When the lower end of the screw shank is brought into contact with the upper surface of the pressing depth adjusting plate n by rotating it laterally (Figs. 5 and 6), the upper part 9 of the height a of the stepped portion 24 is adjusted. It will put pressure on you.

In addition, with the lower end of the screw shaft side in contact with the upper surface of the transfer table l (FIG. 7), turn the adjustment dial 21 so that the lower surface of the pressing part 14 is brought into contact with the upper surface of the front wall 16 of the seedling box 2. When the lower end of the screw shaft 20 is brought into contact with the upper surface of the transfer table 1 by rotating the joint plate with a pressing depth of 7A, the height of the stepped portion 24 is a.
This means pressing 9 times the thickness b of the pressing depth adjusting plate n.

In this case, by forming a plurality of stepped portions 24 of the pressing depth adjusting plate and changing the height of the stepped portions 24, the pressing portion 14 can be
Of course, the height of the stepped portion 24 can be adjusted to match the leveling depth by the rotary brush 8, although the depth of the step 24 can be changed.

Although the corner pressing device 10 is attached to an arm separate from the arm of the rotary brush 8, it may be attached to the arm of the rotary brush 8.

In the case of a single-row seeding device, it is more effective if the pressing portion 14 has protrusions formed at predetermined intervals.

A pressing roll is provided on the transfer table l on the downstream side of the corner pressing device to. The pressing rolls are used to flatten the upper surface of the bed ±9 by pressing the soil clods when the bed ±9 having large grains of soil is filled into the seedling raising box 2. Therefore, the pressure roll is not necessary when using a very fine-grained bed of ±9 and in the case of row seeding, and is not used because it is moved upward by an upward movement holding device M (not shown).

A seed supply device n, a watering device, a soil covering supply device t28, etc. are provided on the front side of the pressing roll.

Moreover, in the seeding device for row seeding, a row roll is provided in place of the pressure roll.

The corner pressing device M10 is described as being incorporated into a seeding device equipped with a bed soil supply device 5, a seed supply device r, a hot water device, a covering soil supply device 28, etc., but it can also be used in a seedling raising box filled with bed soil. It is sufficient that only the rotary brush 8 is provided on the transfer platform 1 capable of horizontally conveying the materials, and the rotary brush 8 is provided next to the rotary brush 8. , the provision on the front side of the seed supply device H is done with care.

(effect) Next, I will explain the effect.

Since the present invention has the above configuration, when the seedling raising boxes 2 are continuously supplied to the transfer table 1, the seedling raising boxes 2 are continuously transported horizontally without any gaps, and the bed soil 9 is supplied by the bed soil supply device N5. It is leveled by a rotary brush 8.

The supply of this floor ±9 is not a method of supplying a small quantity and replenishing it, but a method of supplying a large quantity and removing the excess. Excess soil that cannot be removed by the brush 8 remains.

In the present invention, a corner pressing device 10 is provided on the front side of the rotary brush 8.
is provided, and the corner pressing device lO is provided with a pivot arm 11.1
A corner pressing body 13 in the left and right direction is provided at the tip of the corner pressing body 13, and the lower front side of the corner pressing body 13 is formed into a substantially horizontal pressing part 14, and the rear edge of the pressing part 14 has a shape that is higher toward the rear. Since the inclined guide surface 15 is formed to be inclined as follows,
When the upper edge of the front wall 16 of the seedling raising box 2 comes into contact with the inclined guide surface 15 and moves forward, the corner presser 13 as a whole moves against the inclined guide surface 15.
It moves upward once guided by (Fig. 10).

Since a spring 17 is attached to the rotating arm 11.11, which urges the corner pressing member 13 to rotate downward at all times, the seedling raising box 2 is slidably in contact with the lower surface of the pressing member 14.
When the front wall 16 moves further forward and passes below the pressing part 14, the lower surface of the pressing part 14 descends and presses the corners A to flatten them (FIG. 13).

The lower surface of the pressing part 14 descends on an arc centered on the base of the rotating arm 11.11, and the front end of the pressing part 14 comes into contact with the inner surface of the front wall 16 of the seedling box 2 (see 2), as the seedling raising box 2 moves forward, it descends and reaches the corner A.
Press down to make it flat.

In this case, the corner pressing device ff1lO is a rotary brush 8.
Since it is provided on the front side of the seedling raising box 2, the inner corner A of the front wall 16 of the seedling raising box 2 is flattened regardless of the pressure by the pressure roll path.

That is, when the seedling box 2 is filled with fine-grained bed ±9, and especially in the case of row sowing, the soil in the corner A is already pressed by the corner pressing device 10, although the pressing roll is not used. Since it is flattened, it is sufficient to sow the seed as it is or to form grooves with a row roll, and it can be used for both removal and row sowing.

Therefore, mounting plates 19 are provided at both left and right ends of the connecting rod η.
．． 19 is fixed, and the mounting plate 19.19 is screwed onto the screw shaft side in the vertical direction, so when the lower surface of the pressing part 14 descends to the maximum, the screw shaft is applied, and the lower end of 20 is screwed onto the screw shaft side. side,
The pressing depth adjustment plate 14 provided below the presser contacts the upper surface of η and causes the pressing portion 14 to descend.

That is, an adjustment dial 21 is provided at the upper end of the screw shaft side.
21 is fixed, and the step 24 is provided at the tip of the pressing depth adjusting plate η, so lift the entire corner pressing member 13 by hand against the elasticity of the spring 17 and tighten the screw shaft. Place the lower end of the press on the stepped portion 24 of the pressing depth adjustment plate n! Next, rotate the adjustment dial 21 to bring the lower surface of the pressing part 14 into close contact with the upper surface of the front wall 16 of the seedling raising box 2. Next, rotate the pressing depth adjustment plate 22 to adjust the lower end on the screw shaft side. When the corner presser 13 is brought into contact with the upper surface of the pressing depth adjusting plate, the corner pressing member 13 is lowered from the upper end of the front wall 16 of the seedling raising box 2 by the height a of the stepped portion 24, and reaches the floor ±
You will press 9.

Also, while the lower end of the screw shaft side is in contact with the upper surface of the transfer table l, the adjustment dial 21 is rotated to bring the lower surface of the pressing part 14 into close contact with the upper surface of the front wall 16 of the seedling box 2, and then When the pressing depth adjusting plate is rotated and the lower end of the screw shaft side is brought into contact with the upper surface of the transfer table l, the pressing part 14 is moved to the height a of the stepped part 24 plus the thickness b of the pressing depth adjusting plate. It will descend by an amount of +9 and press the floor +/-9.

Since a pressure roll is provided on the transfer table l on the front side of the corner pressing device to, when a floor ±9 containing coarse soil particles is used, the pressure roll is attached to the floor ±9. Push in the granular soil particles protruding from the top surface of 9 and level it 1
Seeds are supplied by the seed supply device n, and covering soil is supplied by the soil covering supply device, and the sowing operation is completed.

(Effects) In the conventionally known Japanese Utility Model Application Publication No. 60-190244, a pressure roll is provided above a transfer table that transversely transports a seedling raising box filled with bed soil, and a pressure roll is provided on the front side of the pressure roll. It is described that a corner pressing body is provided which moves up and down in unison with the seedling raising box to press the inner corner of the front wall of the seedling raising box.

The above-mentioned known device has a problem in that it is a pressing body that moves up and down integrally with the pressing roll.

In other words, the pressure roll is used to press and flatten the large granular soil lumps (3 mm to 7 + e + w) protruding from the top surface of the bed soil supplied to the seedling nursery box, so all the grains are 2 mm.
The following very fine bed soil does not require compaction, and even in the case of such bed soil, there is a problem that the mound at the corner inside the front wall of the seedling nursery box cannot be flattened unless it is compacted.

In particular, in the case of a seeding device for row seeding, since the grooves are formed by a row roll after the bed soil is supplied, there is no compaction by a pressure roll, so the conventional one cannot be used, and instead of the pressure roll, a row roll is used. Another issue is that a dedicated corner floor soil pressing device is required.

However, the great invention has a transfer table 1 for transversely transporting the seedling-growing box 2, and a bed soil supply device 5 provided above the transfer table 1, in which the bed soil supply device 5 is provided on the seedling box transfer side. A seedling raising method in which a rotary brush 8 for leveling the bed soil is provided, and a pressing body 13 having a pressing part 14 for pressing the inner corner A of the front wall 16 of the seedling raising box 2 is provided next to the rotary brush 8. Since it is a corner bed soil pressing device in the box, it flattens the mound at the inner corner A of the front wall 16 of the seedling raising box 2 regardless of the compaction of the floor ±9, so it is possible to flatten the soil at the inner corner A of the front wall 16 of the seedling raising box 2. This has the effect of widening the scope of use, such as being able to be used as both a seeding device and a seeding device.
