JPS603692Y2 - Row seeding device of powder spreader - Google Patents

Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a powder spreader, mainly a row spreading device attached to a rocking type spreader.

(b) Prior Art Conventionally, powder spreaders have spread powder such as fertilizers and chemicals in the air, usually by shaking or spraying.

However, when spraying fertilizers, seeds, etc., it may be more effective to sow in rows, etc., depending on the type of crop, its size, the width of the rows, etc.

However, this cannot be done with conventional powder spreaders.

On the other hand, as a conventional example, 1 is used as a switching device (conventional example) in a fertilizer applicator in Utility Model Publication No. 35-18031, as shown in Fig. 5.
The introduction pipe 35 connected to the lower opening of the fertilizer dropping cylinder 34 installed below the hopper 32 faces the upper opening of the fertilizer receiving cylinder 36, and the dropping passages 37 and 38 are branched to the left and right at the bottom of the receiving cylinder 36. A pivot rod 41 is provided and rotatably pivoted near the branch part.
A switching device in a fertilizer application machine, which is fixed to a switching valve 41 and has a handle 43 attached to the rear protruding end of the shaft rod 41, and connects fertilization pipes 44 and 45 to the lower mouths of the drop paths 37 and 38. structure.

Known as Yo.

In addition, mounting the row pipe so that it can be rotated is based on the Utility Model Act of 1973.
23527' It is known for its fertilizing and seeding machine.

(c) Problems to be solved by the invention In the conventional example, the fertilizer sent from the hopper into the fall tube is guided into the fertilizer receiver 36 which has a branch fall path at the bottom, and The purpose of the present invention is to provide a switching device for a fertilizer applicator that allows fertilizer to fall to the left or right at will by operating a switching valve provided, and is suitable for powder spreaders, especially conventional rocking type. The purpose of this invention is not to provide a row sowing device for a powder and granular material spreader that can be detachably attached to the powder and granular material spreader and can spread powder and granular materials such as fertilizer in rows according to the width of the furrow, etc. Therefore, the side wall of the fertilizer receiver 36 serves as a barrier to prevent fertilizer, etc. (coming out from the open opening) from scattering, making it possible to keep the overall height of the distribution box low, and making it possible to prevent fertilizer, etc. from entering the row-seeding pipe. It did not have any effects such as no stagnation.

2) Means for understanding the problem This idea consists of forming a wide notch at the top of the front surface that allows the discharge pipe that protrudes from the powder spreader to pass through, and a mountain at the bottom that is raised toward the notch. The distribution tank consists of a molded distribution tank, the base is bent into a dogleg shape with a smooth curved surface, and the row spreading pipe is rotatably attached to the left and right bottom of the distribution tank, and one end is fixed to the distribution tank and the other end is used for distributing powder and granular material. To provide a row spreading device for a powder and granular material spreader, characterized by comprising a mounting plate that is detachably fixed to the machine to position the opening of a discharge pipe in a distribution tank.

(e) Operation When performing row sowing, attach the row sowing device to the powder spreader using a mounting plate, rotate the row sowing pipe and fix the appropriate position.
Following the discharge pipe, the fertilizer etc. from the spreader is discharged from the open port into the distribution tank.

Since the distribution tank has a wide notch in the upper part on the side of the sprayer, the discharge pipe swings in the notch.

Therefore, the side wall of the distribution tank other than the notch serves as a barrier to prevent fertilizer etc. from scattering, and the overall height of the distribution box is kept low.

Fertilizer, etc. smoothly passes through the row seeding pipe and is sown in rows.

Selection between sowing a single row and sowing multiple rows is made by rotating the row sowing tube.

(F) Embodiment An embodiment of this invention will be described based on the drawings. 1 is a row seeding device, 2 is a rocking type powder spreader, and 3 is a rear part of a tractor.

The row seeding device 1 is composed of a distribution tank 4 and a row seeding pipe 5.

The distribution tank 4 has a V-shaped side and a notch 6 at the upper front of the waist.
The bottom part 7 is formed into a medium-high mountain shape with the bottom part 7 raised toward the insertion port of the discharge pipe 23, and holes are bored in the left and right lower parts to provide a connecting part 8.

The bottom portion 7 may be formed flat (not shown).

The connecting portion 8 consists of upper and lower annular plates 9 and 10, a collar 11, and a bolt 12. A gap 13 is formed between the annular plates 9 and 10 by the collar 11 and the bolt 12, and a set screw 14 is attached to and removed from the lower annular plate 10.・Can be screwed freely.

The row tube 5 has two left and right tubes, each of which has a peripheral flange 15 formed at its upper end, and has a base 16 that is bent into a dogleg shape with a smooth curved surface and a linear base 16, as shown in FIGS. 3 and 4. Inclined part 1
7, is rotatably held in the gap 13 of the connecting portion 8 by the peripheral flange 15, and is fixed at an arbitrary position with a set screw 14.

Reference numeral 18 denotes a mounting plate, whose ends are detachably fixed to the distribution tank 4 and the support frame 19 of the rocking type powder spreader 2 with bolts, respectively.

The oscillating powder spreader 2 has a hopper 20 and a shutter 21.
, auxiliary box 22, discharge pipe 23, swing box 24,
It is composed of a support frame 19, a mounting frame 25, a shutter lever 26, and a link rod 27, and is connected to the rear part 3 of the tractor by the mounting frame 25 and a universal joint 28.

The discharge pipe 23 is provided to protrude rearward, and is configured such that its opening 29 is positioned into the distribution tank 4 when the row seeding device 1 is attached to the spreader 2.

The illustrated embodiment shows a case in which the distribution tank 4 is divided into two parts on the left and right sides, but it is also possible to divide the distribution tank into three parts by forming the bottom part 7 of the distribution tank 4 into a knee shape and installing three row pipes 5. It is.

When it is desired to sow powder and granular materials such as fertilizer in rows, the row sowing device 1 is attached to the conventional rocking type powder spreader 2 using the mounting plate 18, and the row sowing pipe 5 is rotated to set the set screw 14 at an appropriate position. Use it by fixing it with.

That is, fertilizer and the like in the hopper 20 are discharged into the distribution tank 4 from the opening 29 through the swinging discharge pipe 23.

Distribution tank 4. As shown in FIG. 2, the upper front surface has a notch 6 wider than the swing width of the discharge pipe, so that the discharge pipe 23
swings within the notch 6.

Therefore, the side wall of the distribution tank 4 other than the notch serves as a barrier to prevent fertilizer etc. from scattering, and the overall height of the distribution box can be kept low.

Fertilizer and the like smoothly pass through the row seeding pipe 5 and are sown in rows.

In FIG. 4, the example in which the row seeding pipe 5 is shown by a solid line is a case where a single row is sown, and the example shown by a dashed dotted line is a case where a plurality of rows are sown.

(g) Effects of the invention Since this invention has the above-mentioned configuration, it can be easily attached to a powder spreader, especially a conventional rocking type spreader, and can be used to spread powder such as fertilizer. It can be sown in rows without scattering the body.

Furthermore, since the plurality of row seeding tubes can be rotated as appropriate, it is possible to sow from a single row to multiple rows of arbitrary width depending on the type, size, width of the furrow, etc. of the crop.

Since the base of the row-seeding pipe is formed with a smooth curved surface, fertilizers, etc. do not stay inside the row-seeding pipe.

Therefore, only the necessary amount of powder or granular material such as fertilizer is used, making it very economical.
