Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fertilizer spreading device for spreading fertilizer in the form of two powder particles onto a field.

[Prior Art and Problems to be Solved by the Invention] Various fertilizer spreading devices of this type have been devised in the past, and the one disclosed in Japanese Utility Model Publication No. 14818/1983 is known.

However, since these fertilizer spreading devices are so-called specialized machines for spreading fertilizer, they cannot be used for general purposes or for multiple purposes, and this poses an economic burden for some farmers.

[Means for solving problems]

The purpose of the present invention is to eliminate these inconveniences, and its gist is that a transport platform that is connected to a traveling machine and that enables soil transport and snow removal is provided with fertilizer dispensing holes for dropping fertilizer in parallel. A fertilizer spreading device characterized in that a protector for protecting the fertilizer spreading hole when fertilizer is not being spread is detachably provided on the transport platform.

[For production]

The field is attached to the mounting frame 3 through the upper entry section by the movement of the traveling machine.
The mounting frame 3 can be vertically moved by the hydraulic swing of the swing arm 6.

8 is a carrier, and the carrier 8 has a bottom plate 9. Before.

Board 10. Left and right side wall plates 11. It is formed into a box shape by a rear plate 12, and the left and right side wall plates 11 and the rear plate 12 are configured to be horizontally foldable.

Further, the mounting frame 3 is formed in a side-sided shape, and its horizontal portion 3
a is pivotally attached to the lower part of both sides of the carrier 8 by a fulcrum shaft 13, and the front plate 10 is brought into contact with the vertical portion 3b, and the mounting frame 3 and the carrier 8 are locked by the holding mechanism 14, that is, the vertical The hook rod 15 of the part 31) is hooked to the hook rod 16 of the front plate 11 by the action of the spring member 17 to hold the carrier 8, and when released, the carrier 8 is configured to tilt backward about the fulcrum shaft 13. has been done.

Further, the fertilizer spreading hole 18 is formed by opening a guide plate 19 in the front part of the bottom plate 9 at a predetermined pitch in the left-right direction, and a long slide plate 20 is arranged on the inner surface of the hole so as to be slidable left and right by the guide plate 19. Fertilizer spreading holes 18 are formed in this slide plate 20.
A through hole 21 of the same diameter and pitch is bored, and an engagement pin 22 is provided protrudingly on the slide plate 20, while the lower part of the adjustment lever 23 is pivotally connected to the front plate 10 with a center pin 24. In addition, a position regulating plate 25 is attached to the front plate 1.0, and this position regulating plate 2
The upper part of the adjustment lever 23 is engaged with the toothed part 26 of 5 by the spring elastic action of the adjustment lever 23 itself, and the lower end of the adjustment lever 23 is
A U-shaped groove 27 is formed, and this U-shaped groove 27 is inserted into the engagement pin 22.
, presses the adjustment lever 23 toward the front plate 10 side, separates the adjustment lever 23 from the toothed portion 26, and then moves the adjustment lever 23 as it is.
The effective diameter of the fertilizer spreading hole 18 can be adjusted by swinging around the center pin 24 and sliding the slide plate 20 left and right.

Reference numeral 28 denotes a vibration mechanism, in which a holding frame 29 is attached between the vertical parts 31) of the mounting frame 3 with bolts 30, and a rotating shaft 31 is mounted on the holding frame 29 with a bearing 32 so as to rotate. An eccentric weight ring 33 is attached to this rotating shaft 31, and a flexible joint 35 connects the rotating shaft 31 and the power take-off shaft 34 of the traveling aircraft l.
and rotate the rotating shaft 31 with the power extraction shaft 34,
The entire mounting frame 4 is made to swing due to the eccentric weight action of the eccentric weight ring 33.

Reference numeral 36 denotes a superior entry portion, which is formed in the shape of a triangular blade at the rear edge of the opening of the bottom plate 9.

Since this first embodiment has the above-mentioned configuration, fertilizer in the form of one powder or the like is stored in the transport platform 8, the opening amount of the fertilizer spreading hole 18 is adjusted by the adjustment lever 23, and the power take-off shaft 34 is rotated. When the eccentric weight ring 33 is rotated, the mounting frame 3 is vibrated, and the traveling body l is moved forward, the fertilizer a falls from the fertilizer spreading hole 18, and the fertilizer a can be sprinkled on the field.

At this time, as shown in FIG. 1, if the transport platform 8 is placed in an upwardly rearward inclined manner by the connecting mechanism 2, the fertilizer a can be smoothly transferred on the bottom plate 9 toward the fertilizer spreading hole 18.

Further, the remaining fertilizer in the carrier 8 can be discharged by releasing the holding mechanism 14 and tilting the carrier 8 backward.

In addition, as shown in FIG. 7, by removing the rear plate 12 of the transport platform 8 and moving the traveling machine 1 backward, the field soil can be scraped out by the upper entry part 36 and introduced into the transport platform 8, and the soil at high places can be removed. is introduced in advance, the holding mechanism 14 is released at a low place, and the earth and sand in the transport platform 8 is discharged, thereby making it possible to perform land leveling work to correct the height of the field.

In addition, by traveling the traveling body 1, the soil introducing portion 36
It can be used to level the earth and sand, and especially to clear snow.

The second embodiment shown in FIG. 8 differs from the first embodiment in that the horizontal portion 3a of the mounting frame 3 is pivotally connected to the left and right side wall plates 11 of the carrier 8 by a fulcrum shaft 13. Obtain similar effects.

In addition, the position of the fertilizer spreading hole 18 is at the bottom of the transport platform 8.

For example, it can be applied to the boundary between the front plate 10 and the bottom plate 9 or a position near the boundary, or to the boundary between the rear plate 12 and the bottom plate 9 or a position near the boundary.

Further, the shape of the main introduction part 36 is not limited to the triangular blade shape.
Plane wave blade-like ones can be used intermittently.

Next, the protector A for the fertilizer spreading hole 18 of the present invention will be described in detail.

When the fertilizer spreading holes 18 are drilled in parallel, a protective body (the drawing shows an inverted dish-shaped cross section) has the width and length to hide all of the holes (in the case of multiple rows, the width to hide all of them).棧板)
Place.

This protector A is fastened using a suitable fastener opening.

The drawing shows fertilizer spreading holes 1 on the left and right of the protector A or in three locations.
The figure shows a case in which a bolt hole C that matches No. 8 is provided, a regular bolt 2 is inserted into this bolt hole C, and the nut is tightened through a washer E to fix it in a removable manner. method may be adopted.

〔Effect of the invention〕

According to the present invention, when spreading fertilizer, the protective body can be removed and the fertilizer spreading operation can be carried out as desired by leaving all the fertilizer spreading holes open.

Next time you carry out soil transport or work on the pond, you will not be spreading fertilizer, so protect the fertilizer spreading hole with a protector, and then carry out other work such as soil transport or snow removal in this protected state. By doing this, it is possible to reliably prevent soil from becoming clogged in the fertilizer application holes or damage to the fertilizer application holes.

In particular, when the small fertilizer application holes become clogged with soil, it is extremely troublesome to remove the clogs by poking them one by one with a stick. It has excellent practicality as it is easy to remove and put on and take off the protective body.

As described above, the present invention can uniformly spread fertilizer over a field through the fertilizer distribution hole, can perform soil leveling work, and can also perform various management work and transport work of harvested products, and can be used as a general-purpose tractor. , it can be used for multiple purposes.

As described above, the intended purpose can be fully achieved.
