ものである。 [Detailed Description of the Invention] The present invention relates to a chute device for an oscillating fertilizer spreader, and aims to provide a fertilizer spreader with a simple structure and high spreading accuracy. Several proposals have been made to try to achieve this goal, but
If the structure is complicated or if the spray is spread over a wide area, the particles scattered at the end of the spray side will come into contact with the supporting members, etc. and the centrifugal force (release force) will be weakened, and it will be affected by slight winds, making it difficult to maintain the desired spray accuracy. There were some problems, such as not being able to get it. In view of this point, the present invention has wide vertical plates at the top and bottom opposite to the direction of fertilizer release at the end of the spreading tube, and spaces of appropriate width, which are spread symmetrically, and an inclined plate is installed at the bottom. A chute device for a rocking fertilizer spreader is provided, characterized in that collision plates are erected at both ends of the inclined plate, and the fertilizer material to be discharged to a long distance at the end position of the spreading side is released into a space. The present invention provides a revolutionary chute device for a rocking fertilizer spreader that directly discharges the fertilizer without losing centrifugal force and achieves highly accurate spraying even in wide, wide-angle rocking spread. Next, the present invention will be explained based on the drawings in which the invention is implemented. Reference numeral 1 denotes a tractor, and the front part of a frame 2 is connected to a three-point link device. The frame 2 supports the hopper 3, etc. Reference numeral 4 denotes a drive transmission, which receives input from the PTO shaft (not shown) of the tractor 1 via the rotating shaft 5 to swing the spray barrel 6 at high speed. The dispersing cylinder 6 has a somewhat tapered cylindrical body, and a mounting bracket 7 is welded to the tip in a vertically parallel manner. Reference numeral 8 denotes long holes, which are provided on the left and right sides of the distal end of the dispersion cylinder 6.
13 is a control member, and a mounting bracket 7 is attached to the tip of the spray tube 6.
The control member 13 is fixed via the. Control member 13
are a vertical plate 9, a space 10, an inclined plate 11, and a collision plate 1.
2. The connecting plates 14a and 14b are made of thin plate material. Reference numeral 9 denotes vertical plates, which are wide thin plates placed one above the other in opposition to the direction in which the fertilizer substance is released, and in this example, three of them were placed. Reference numeral 10 is a space formed to have an appropriate width. At the bottom of this vertical plate 9 is an inclined plate 1.
Collision plates 1 are installed obliquely on both sides of the inclined plate 11.
2 is tilted to the side and erected. The control member 13 has a general shape when viewed from the side. Incidentally, the long holes 8 are formed as desired, and are particularly effective in sandy minerals. Next, the effect will be explained. The fertilizer falling from the hopper 3 is agitated by the agitator 16, collected by the sub-hopper 15, and passed through the bottom of the spray tube 6.
is emitted along the sidewalls of the For example, the arrow schematically shown in FIG.
oscillates in the F direction, and as the fertilizer substance moves from the center to the reciprocating point, the release amount changes from _f1 to _f7 . Here, what is directly discharged into the space 10 retains a strong centrifugal force and is discharged far away.
However, the particles that come into contact with the vertical plate 9 and the collision plate 12 are scattered in a corrected direction such as f ₃ , f ₅ , or f ₇ and are scattered near the center of the spray range. Figure 6 is a graph (A) showing the spraying accuracy obtained in this example, and (B) is a graph showing the case where the tip of the sprayer cylinder is not treated at all. It represents the characteristics of Therefore, since the vertical plates 9 of the control member 13 of the present invention are arranged in several rows while having a wide space 10, the vertical plates 9 and the collision plate 12 are arranged in several rows.
Those that come into contact with the space are scattered at the center (C) position of the graph each time they reciprocate like f ₃ , f ₅ , or f ₇ , and those that are ejected directly from the space with centrifugal force are directed to the far side. The result is a suitably smooth scatter graph. Most of the released fertilizer that comes into contact with the center one of the vertical plates 9 is scattered near the center (C) of the graph, and the vertical plates 9 and collision plates 12 on both sides are scattered near the center (B) of the scatter graph. The main function is to scatter and even out the accumulated dispersion on both sides as shown in the figure. In addition, a part of the released fertilizer material comes into contact with the inclined plate 11 at the bottom of the vertical plate 9, loses centrifugal force while moving along the inclined surface, and is diffused and distributed near the center (C), resulting in overall dispersion. It has the effect of further improving accuracy. With the above configuration, it is possible to spray over a wide angle range with high precision, and the fertilizer substances released from the space where they are sprayed in a distant area maintain a strong centrifugal force and are not affected by weak winds. Achieving the desired accuracy without any problems. In addition, since the control member at the tip is made of thin plate material that spans the top and bottom, it is lightweight and has a strong impact resistance effect.
