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 powder, granules, etc. onto a field.

[Problems to be solved by conventional technology and invention]

Hitherto, various types of fertilizer spreading devices have been devised, and one of them is known as Utility Model Publication No. 14818/1983.

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

[Means for solving problems]

The purpose of the present invention is to solve these inconveniences, and its gist is to connect a mounting frame to a traveling machine body by a coupling mechanism, and to provide a transport platform on which powdered, granular, etc. fertilizer is placed on the mounting frame. The fertilizer spreading device is characterized in that a plurality of fertilizer spreading holes are formed in the transport platform, and a movable member is provided above the fertilizer spreading holes to promote the fall of the fertilizer.

[Effect]

When the traveling body travels, the fertilizer in the transport platform falls in a scattered manner from the fertilizer spreading holes, and at this time, the movable member forces the fertilizer in the fertilizer spreading device to move, thereby promoting the fall of the fertilizer.

Further, the fertilizer spreading hole 18 is connected to a guide plate 19 at the front of the bottom plate 9.
The holes are opened at a predetermined pitch in the left-right direction, and a long slide plate 20 is disposed on the lower surface of the hole so as to be slidable left and right,
A through hole 21 having the same diameter and pitch as the fertilizer spreading hole 18 is bored in this slide plate 20, and an engaging pin 22 is provided protrudingly in the slide plate 20, while the lower part of the adjustment lever 23 is centered on the front plate 10. The position regulating plate 25 is attached to the front @ 10 by a pin 24, and the upper part of the adjusting lever 23 is engaged with the toothed part 26 of the position regulating plate 25 by the elasticity of the adjusting lever 23 itself. A U-shaped groove 27 is formed at the bottom of the U-shaped groove 23, and this U-shaped WI
I27 is engaged with the engagement pin 22, the adjustment lever 23 is pushed toward the front plate 10 side, the adjustment lever 23 is separated from the toothed part 26, and the adjustment lever 23 is swung around the center pin 24, By sliding the slide plate 20 left and right, the opening amount of the fertilizer spreading hole 18 can be adjusted.

Reference numeral 28 denotes a movable member, and the movable member 28 is formed in a comb shape. In this case, a plow member 29 is attached to the lower part of the mounting frame 3 in a detachable or retractable manner, and the front plate 1 is attached in correspondence with the plow member 29.
(The upper groove entrance 3G is formed on l, and the upper groove entrance 3G is formed on the front plate IO.
A blocking plate 31 is provided to block the air, a bearing 32 is provided on the blocking plate 31, a rotating shaft 33 is supported on the bearing 32, and the rotating shaft 33 and the power take-off shaft 34 of the traveling body l are connected with a universal joint 35.
An eccentric cam 36 is fixed to the rotating shaft 33, two link members 38 are suspended from the upper part of the front plate lO by pins 37, the two link members 38 are brought into contact with the eccentric cam 36, and the two link members 38 A movable member 28 is pivotally connected to the lower part of the movable member 28 by a pin 39.

Reference numeral 40 denotes an upper groove 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, powdered, granular, etc. fertilizer is stored in the transport platform s, 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 cam 36 is rotated and the movable member 28 is reciprocated to move the traveling machine l forward, fertilizer a is released from the fertilizer spreading hole 18.
falls, and the fertilizer a can be sprinkled on the field, and at this time, the fertilizer a above the fertilizer distribution hole 18 is forcibly moved, the fall of the fertilizer a is promoted, and the fertilizer a can be spread properly. be able to.

Furthermore, if the transport platform 8 is placed in an upwardly rearwardly 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.

In addition, by removing the blocking plate 31 equipped with the rotating shaft 33, etc., removing the rear plate 12 of the transport platform 8, and moving the traveling machine 1 backward, the field soil is scraped out by the upper grooving part 40 and introduced into the transport platform 8.
