Description

[Detailed description of the invention] This invention relates to the improvement of a roll-type feeder for agricultural powder and granules, and is capable of handling from relatively large seeds such as rice, wheat, and soybeans to relatively small seeds such as radish and rapeseed. Alternatively, the purpose is to make it possible to dispense everything from chemical fertilizer to Digeston fertilizer with one roll.

A hopper containing agricultural powder and granules such as seeds and fertilizers has a first feeding roll having feeding grooves in the roll axis direction formed at intervals in the circumferential direction on the outer periphery, and a first feeding roll in which feeding grooves in the roll axis direction are formed at intervals in the circumferential direction. A roll-type feed-out device is known which is formed by combining a second feed-out roll having a feed-out amount adjustment piece that is movably fitted therein.

This type of feeding device slides the second feeding roll in the axial direction, and depending on the extent to which the adjusting piece closes the feeding groove, it can be used to feed out large or small particles, for example, from large particles to small particles. Adjustments between the two are possible.

However, the feeding groove has a considerable depth in order to accommodate the powder and granules, and therefore, if the feeding groove is completely closed with the adjustment piece, it will naturally become impossible to feed out the powder.

However, agricultural powders range from large grains such as soybeans to small grains such as radish, and there are times when it is necessary to feed out a small amount of small particles, and in such cases, the rolls must be replaced each time. This was extremely troublesome.

Therefore, with this invention, it is possible to adjust the feeding from large particles to small particles, and it is also possible to feed out small amounts of small particles with one roll.
It is possible to feed everything from soybeans, etc. to radish, rapeseed, etc., or from chemical fertilizers to fertilizers such as Digestion with a single roll. A first feeding roll having feeding grooves in the roll axial direction formed at intervals in the circumferential direction on the outer periphery, and a feeding amount adjustment piece fitted in the feeding groove of the roll so as to be slidable in the roll axial direction. In a roll-type feeding device provided in combination with two feeding rolls, when the feeding groove is completely closed by the feeding amount adjusting piece, the groove width is smaller than the groove width of the feeding groove and the groove depth of the feeding groove is shallower. The present invention provides a roll type feeding device for agricultural powder and granular material, characterized in that a concave portion with a minimum feeding amount is formed on the outer periphery of the second feeding roll so as to face the inside of the hopper.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example in which an agricultural granular material working machine 2 such as a seeding machine or a fertilizer applicator is connected to a tractor 1 via a link mechanism 3 so as to be movable up and down.

The working machine 2 is equipped with a hopper 4 and a roll type feeding device 5 shown in FIG. An example is shown in which the object is dropped to the ground through the soil cover member 8 and can be covered with soil.

Referring to FIG. 2, details of the roll-type dispensing device 5 are shown, and FIG. 3 shows an exploded perspective view of the dispensing roll.

The hopper 4 is provided with an inlet 9 for agricultural granular material A such as seeds and fertilizers, as shown in FIG.
2 is provided.

The first feeding roll 11 has feeding grooves 13 in the roll axis direction formed at intervals in the circumferential direction on the outer circumference, and can be freely adjusted and fixed in the axial direction by inserting and removing a pin 15 on the shaft 14 of the drive wheel 6. The two-feeding roll 12 has a feeding amount adjustment piece 16 that is fitted into the feeding groove 13 so as to be slidable in the roll axis direction, and can be adjusted and fixed in the roll axis direction by a screw structure 17.

That is, the innermost vertical surface 13A of the feeding groove 13 is located on substantially the same vertical plane as one vertical surface 10A of the funnel section 10, and the end surface 16A of the adjustment piece 16 is positioned on the other vertical surface of the funnel section 10. 10B, the amount of feeding is maximized and the end face 1
6A is superimposed on the vertical surface portion 13A and fully closed, a recess 18 located inside the hopper 4, that is, inward from the vertical surface portion 10B of the funnel portion 10, is formed at the base of the adjustment piece 16 in this example. has been done.

Therefore, the concave portion 18 is designed to have a minimum amount of feeding.In other words, the groove width and groove depth of the feeding groove 13 are designed to accommodate relatively large particles such as rice, wheat, and soybeans. The diameter and depth are designed to accommodate a very small amount of small particles such as rapeseed.

That is, the concave portion 18 is made smaller than the groove width of the feeding groove 13 and shallower than the groove depth of the feeding groove 13, thereby achieving the minimum feeding amount.

Note that the roll type feeding device 5, which is rotated via the drive wheel 6 and feeds out the granular material A, is equipped with a metering brush, etc. not shown.

Next, the action will be explained.

When the drive wheel 6 is rotated as the tractor 1 travels, the roll-type feeding device 5 is rotated counterclockwise in FIG. The powder and granular material A is sequentially fed out through the sheet 7 under the feeding amount determined by the fixing method.

Therefore, relatively large particles A of soybeans, rice, etc.
can be delivered a predetermined amount.

Next, in order to feed out a small amount of small particles such as radish or rapeseed, the end surface 16A of the adjusting piece 16 is connected to the groove vertical surface 13.
If the distance is slightly greater than A, accurate feeding becomes difficult because the groove width and groove depth of the feeding groove 13 are designed for large particles such as soybeans as described above.

Therefore, in such a case, the second feeding roll 12 is slid to the right in FIG. It is fully closed by the adjustment piece 16, and at this time, the recess 18 is positioned within the hopper 4.

In addition, at this time, the first feeding roll 11 is attached to the pin 1.
It is desirable to move the roll 11 a little to the right by removing the pin 5 and inserting it into the pin insertion hole 15A shown in FIG. The rightward movement of the roll 11 may be achieved by a screw structure in addition to the above-mentioned insertion and removal of the pin 15, and the cover 19 can be fixed with bolts 20 for such adjustment.

The present invention includes a first feeding roll 11 in which feeding grooves 13 in the roll axis direction are formed at intervals in the circumferential direction on the outer periphery of a hopper 4 in which agricultural granular materials A such as seeds and fertilizers are stored; In a roll-type feeding device 5 provided in combination with a second feeding roll 12 having a feeding amount adjusting piece 16 that is slidably fitted in the feeding groove 13 in the roll axis direction, the feeding groove 13 adjusts the feeding amount. When the adjusting piece 16 is fully closed, the recess 18, which is smaller than the width of the feeding groove 13 and shallower than the depth of the feeding groove 13 to achieve the minimum feeding amount, faces the inside of the hopper 4. Since the present invention relates to a roll-type feeding device for agricultural powder and granular material, which is characterized in that it is formed on the outer periphery of the roll 12, it has the following advantages.

That is, for example, a roll device for feeding rice, wheat, soybeans, etc. can be used to feed small amounts of radish, rapeseed, etc., and a chemical fertilizer feeding roller device can be used to apply Digestion, and here, the same A wide variety of agricultural powder and granules can be accurately fed out using rolls.
