Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention [Industrial Application Field] The present invention relates to an earth and sand supply device used, for example, when supplying a bed or covering soil to a seedling box for raising seedlings.

[Prior Art] The above-mentioned earth and sand supply device includes a hopper for temporarily storing earth and sand, and a belt conveyor type feeding device provided at the bottom of the hopper. There is a device that uses a feeding device to feed out the earth and sand in the hopper. As shown in Utility Model Publication No. 51-41776,
"Soil delivery device" is an example of this, and in the specification, the delivery device is referred to as "soil delivery mechanism" and the delivery port is referred to as "soil delivery section." The soil delivery section of this soil delivery device is equipped with a soil delivery adjustment plate that can be adjusted up and down, and a shutter that is rotatably attached to the bottom end of the adjustment plate. By changing the size and adjusting the opening area of the soil delivery section, the delivery amount is adjusted, and by raising and lowering the shutter to open and close the soil delivery section, soil supply is started and stopped.

[Problem to be Solved by the Invention J] However, with the soil supply device having the above configuration, it is not possible to temporarily change the opening area of the outlet with a simple operation during the soil dispensing operation. There was a problem in that if large clods of earth, stones, etc., clogged the shutter, they could not be removed, resulting in poor soil delivery.

Structure of the Invention [Means for Solving the Problems] In order to solve the above problems, the present invention has the following structure.

That is, the earth and sand supply device according to the present invention is as follows.

It is equipped with a hopper for temporarily storing earth and sand, and a belt conveyor-type feeding device provided at the bottom of the hopper, and the earth and sand in the hopper is drawn out by the feeding device from a feeding opening formed on the wall of the hopper. In the earth and sand supply device, a feed-out amount adjusting plate for adjusting the opening area of the feeding outlet is attached, a holding means for holding the adjusting plate at a position where the opening area is constant, and a holding means for holding the adjusting plate at a position where the opening area is widened. The present invention is characterized in that it is provided with an operating means that can temporarily move the adjustment plate in the direction.

[Function] The holding means normally holds the feeding amount adjusting plate at a position where the opening area of the feeding port is constant. When the adjusting plate is clogged with clods of earth, stones, etc., the adjusting plate is moved in a direction to widen the opening area using the operating means to temporarily increase the amount of earth and sand delivered and remove the clods, stones, etc.

[Example] Figure 1 shows an example of a seeding machine. tl
are a belt conveyor 2a and a roller conveyor 2b,
. . . On top of the transport device fi2 consisting of..., a bed filling device 4, a seeding device 15. A irrigation device 6 and a soil covering device 7 are provided in order along the conveyance direction (arrow X direction). This sowing a1
The seedling box 8 used for this purpose is shaped like a rectangular dish with a shallow bottom, and the bottom is provided with numerous small holes for drainage. The seedling boxes 8 are continuously supplied one by one from the starting end side of the belt conveyor 2a without any gaps. Each device will be explained in detail below.

Floor soil filling M4 and soil covering! Reference numeral 7 indicates a soil supply device having a similar structure, and both are constructed like a tsuza.

In other words, these soil supply devices.

A hopper 10 containing soil for flooring or covering soil is installed above the conveying device 12, and a belt conveyor type feeding device 12 is provided adjacent to the bottom opening 11 of the hopper 10. The feeding device 12 is rotatably driven in a direction opposite to the direction of conveyance of the seedling box (counter-arrow X direction), and a feeding port 14 is formed in the hopper wall surface on the terminal end side of the feeding device. The feeding opening 14 is provided with a feeding amount adjusting shutter 15 which serves both to open and close the feeding opening and to adjust the opening area thereof. This shutter 15 is fixed to the tip of a support member 18 that is pivotally supported by a support shaft 17 installed laterally on the side of the hopper 10, and is rotatable up and down about the support shaft 17. A shutter handle 19, which is an operating means for opening and closing the shutter, is integrally attached to the support member 18 on the opposite side of the shutter 15 across the support shaft 17. Also.

A cylindrical retaining member 21 is provided protruding from the side surface of the support member 1B, and an engaging plate 23 fitted with the feeding amount adjusting screw 22 is engaged with this. The feed-out amount-setting screw 22 is screwed onto the outer box 25, and can be moved forward or backward by turning a handle knob 26 fixedly integrated with the end thereof.

Note that the engagement plate 23 has a spring 27 that loosely fits into the screw 22.
The engaging member 21 is elastically biased by the engaging member 21. These constitute a holding means for holding the feeding amount adjusting shutter at a constant position during the upper edge work.

When using this soil supply device, the shutter handle 19 is lowered until the engagement member 21 comes into contact with the engagement plate 23, as shown by the solid line in FIG. 2, and the outlet 14 is opened. As the feeding amount adjusting screw 22 is screwed in, the opening area of the feeding port 14 becomes smaller and the upper edge amount is reduced, and as the screw 22 is loosened, the opening area of the feeding port becomes larger and the upper edge projecting amount increases. As shown in Figure 6, if debris S such as clods of soil or stones gets caught in the shutter 15, the amount of soil delivered becomes uneven. In such a case.

The shutter handle 19 can be removed by pushing down the shutter handle 19 with your hand to raise the shutter 15 as shown by the chain line to wash away the debris S along with the soil.
When the shutter 15 is released, the action of the spring 27 causes the shutter 15 to return to its original position. - A similar operation can be performed when it is desired to temporarily increase the amount of upper edge protrusion.

In the seeding device 5, a funnel-shaped hopper 30 for storing seeds has an opening 32 elongated in the width direction formed at the bottom thereof, and a seeding roll 33 is provided directly below the opening. Seeding roll 3
3, as shown in Fig. 6, has an IR spiral seed holding recess with a curved bottom surface and a slight twist (about 0 = 15 degrees) with respect to the axial direction, and a diameter of 1 seed. The circumferential groove 36. is also narrower in width and deeper than the recess 35. ...is formed. The seeding roll 33 has a roll shaft 37 installed horizontally.
It is rotatably driven by a motor (not shown). By switching the rotation direction of the motor 39, the seeding roll 39 can be rotated in either forward or reverse direction. A pair of left and right brushes 40, 40 are attached to the lower end of the hopper 30 so that their tips are in contact with the outer peripheral surface of the seeding roll 33. Further, a roll scraper 41 is attached to the horizontal shaft 42, in which a plurality of thin scraper plates 41a, . The scraper plate 41a extends in an arc shape along the groove 36 so as not to be exposed to the seed holding recess 35, and
The tip of the seed holding recess 3 is located on the lower side of the seed holding recess 3.
It stands out within 5.

Furthermore, a row plate 44 is rotatably attached to the roll shaft 37 via bushings 43 and 43.
The row sowing plate 44 has a seed passage 48 formed on the lower side of the sowing roll 33, and further below the seed passage 48 there is a sowing opening 50 partitioned by equally spaced row sowing guides 49, . . .
．． The upper part of the six seed passages 48, in which the six seeds are arranged side by side, is open, and this serves as the seeding opening 51 during sowing.
52a and 52b in the figure are threaded rods for fixing the row-seeding plate 44 at the row-seeding position or the scattering position, and are adapted to engage with engaging portions 53a, 53b of the row-seeding plate.

On the upper side of the storage box 31 of the seeding roller 33, there is a row-cropping roller 5.
5, the 0-row rollers 55 each having a pressure roller 56 on the sewing side are connected to the seeding opening 50 of the row-seeding plate 44. The pressure roller 56 is a roller on which a brim-like strip ring is formed in correspondence with the roller 56, and the pressure roller 56 is a roller with a smooth surface.

The M rollers 55, 56 are pressed onto the floor of the seedling box with constant pressure by pressure rods 57, 58. Further, both rollers are forcibly rotated at a speed equal to the moving speed of the seedling box.

When performing row sowing in the seedling box 8, a row sowing plate 44 is provided as shown by iA in FIG. ! A plurality of seeding grooves 61. During the zero-row sowing where... is formed, the sowing roll 33 is rotated in the direction of the arrow Y.

The seeds 62 held in the seed holding recess 35 are carried to the lower side of the seeding roll and dropped into the seed passage 48 of the single-row seeding plate 44. At this time, the seed holding recess 35. ... is twisted around the axis of the roll, so the seeds flow smoothly.

The seeds 62 dropped into the six-seed passageway 48, which is less prone to seed clogging, are placed in the seeding port 50. The upper surface of the four-child holding recess 34 that is supplied by falling into the seeding groove from... is the brush 40.
Each recess 35. is leveled and excess seeds are removed from the recess. The amount of seeds retained within ... is constant. Furthermore, when the recess 35 rotates to a predetermined position, the tip of the scraper plate 41a is inserted into the recess, and the seeds held therein are forcibly ejected. The timing of each seed falling is also constant. Note that the edge 10a of the seedling box 8 is the seeding port 50.
When passing under ・, the row sowing plate 44 is flipped up as shown by the chain line B in the t53 diagram. After sowing,
The pressing roll 56 crushes the seeding grooves 61 and at the same time lightly presses the floor surface.

Next, when performing seeding, as shown by the chain line C in FIG. The roller 55 and the pressure roller 56 are unnecessary, so remove them, and then rotate the seeding roll 33 in the opposite direction to the direction of row sowing (counter to the direction of arrow Y), and spread the seeds onto the bed from the upper side of the seeding roll 33. Distributed supply.

The watering device W16 is a device for watering the seedling box 8 after sowing, and is provided with a plurality of watering nozzles (not shown) on the ceiling. In the case of sowing, it is preferable to perform irrigation before sowing in order to prevent seeds from being washed away by irrigation, so the arrangement may be such that the sowing device m5 and the irrigation device 6 are interchangeable.

C. Effects of the Invention As is clear from the above explanation, the earth and sand supply device according to the present invention is capable of operating the operation device when clods, stones, etc. become clogged with the feeding amount WR stone plate of the feeding port during the upper edging work. By moving the feeding amount adjusting plate in the direction of increasing the opening area of the feeding port and temporarily increasing the amount of soil being fed out, these clods and stones can be easily removed, ensuring that the soil is always uniform and good. We are now able to supply.
