Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for discharging fertilizers, pesticides, etc. in the form of seeds, granules, etc., evenly divided and discharged from a plurality of discharge ports in a seeding machine, a fertilizer, a pesticide sprayer, etc. It is related to the device.

For multi-row seeding machines, or fertilizers and pesticide sprayers that apply powdered fertilizers and pesticides in multiple rows,
Seeds, granular fertilizers, or pesticides must be distributed evenly to each row, but conventionally, seeds, granular fertilizers, or pesticides are blown out from one end of a single feed pipe that has multiple outlets. Delivered with pressure air,
It was extremely difficult to divide and discharge equal amounts from each outlet.

In other words, the blowing compressed air flows evenly throughout the pipe, but the amount of seeds, granular fertilizers, or agricultural chemicals that are sent on top of it is often small and the distribution density within the pipe is low. Even if the amount of discharge from each outlet of the pipe is adjusted in advance to be equal, there is a drawback that if the feed amount changes, the amounts of each division will be unequal.

Therefore, in view of the above-mentioned drawbacks of the conventional art, the present invention concentrates the conveyed material in the center with a funnel of a quantitative dividing device installed corresponding to each discharge port of the conduit, and then uses a dividing tube and a residual amount release tube. By dividing by
To provide a fixed-quantity dividing discharge device capable of uniformly discharging seeds, granular fertilizers, agricultural chemicals, etc. from each discharge port even if the amount of fertilizer, agricultural chemicals, etc. to be fed is small and the amount changes.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a feed pipe, and the feed pipe 1 has a plurality of discharge ports 2. Reference numeral 3 denotes a metering divider, which has a funnel 6 in the front part of a cylinder that is closely installed in the feed pipe 1, and a dividing tube 4, 4' and a residual amount release tube 5 behind it. It is formed by forming. The funnel 6 has a large-diameter entrance at the front so that the objects to be conveyed, such as seeds, granular fertilizers, or agricultural chemicals, can be concentrated in the center.
It also has a small diameter outlet at the rear. The opening ratio of the divided tubes 4, 4' and the residual amount release tube 5 is adjustable or set to a predetermined value.

The quantitative dividing tool 3 is attached to the feed pipe 1 at each outlet 2.
The entrance of the funnel 6 faces the conveyance direction A of the conveyed object, and the divided cylinder 4,
4' is connected to each outlet 2.

To explain the function when used as a seeding machine,
Seeds are sent from a separate hopper (not shown) into the feed pipe 1 from one end as shown by arrow A in Figure 3 on the pressure air (in the case where the feed pipe has 10 outlets). Enter the first quantitative dividing tool 3,
In the metering divider 3, the ratio of the dividing tubes 4 and 4 and the residual amount release tube 5 is set at 1:9, so that the amount of seeds sent into the feed pipe 1 from the first discharge port 2 is reduced. 1/10 is discharged, and the remaining 9/10 passes through the remaining amount opening tube 5 and enters the next quantitative dividing tool 3, and is divided again, but the first quantitative dividing tool 3 has already reduced the amount to 1/10. Since 10 seeds have been discharged, the ratio of the dividing tubes 4 and 4' in the second fixed quantity dividing tool 3 and the remaining amount release tube 5 is adjusted to be 1:8. Therefore, 1/9 of the remaining 9/10 after being discharged from the first discharge port 2 (overall, the same amount as the first 1/10) is discharged from the second discharge port 2, The remaining 8/9 seeds move toward the third quantitative dividing tool 3. In this way, after passing through the third and fourth quantitative dividing tools 3, in the tenth quantitative dividing tool 3, 1/1 of 1/10, that is, the entire amount in the quantitative dividing tool 3 is reduced to the 10th quantitative dividing tool 3. Since the amount is equal to 1/10 of the amount in the first quantitative dividing tool 3, all of the divided tubes 4 and 4' are used in the tenth quantitative dividing device 3, and the remaining amount release tube 5 is not necessary.

By the way, in each quantitative dividing device 3 as described above, the seeds conveyed by the blowing pressure in the feed pipe 1 are always concentrated in the center by the funnel 6, and are separated from the dividing tubes 4, 4' and the remaining seeds. Since the seeds are divided by the amount release cylinder 5, even if the amount of seeds fed is small, the amount of divided seeds will not change due to the concentrated action of the funnel 6, and the amount of seeds fed will not change. However, all of the liquid is discharged equally from each discharge port 2.

In short, the present invention comprises a conduit pipe having a plurality of discharge ports, a funnel for concentrating the conveyed material in the front part, and a divided pipe and a residual quantity release pipe formed behind the funnel. A metering divider is installed inside corresponding to each discharge port, and a dividing tube of each metering divider is connected to each corresponding discharge port, and each metering divider is connected to an opening between the dividing tube and the remaining amount release tube. The weight ratio is gradually decreased in the feeding direction of the conveyed object so that the conveyed object is divided into equal parts and discharged from all the discharge ports, and then the conveyed object is conveyed by blowing pressure air from one end of the feed pipe. Seeds, granular fertilizers, pesticides, etc.
It is possible to concentrate fertilizers, agricultural chemicals, etc. in the form of seeds, granules, etc. by concentrating them in the center using a quantitative dividing device funnel built in corresponding to each discharge port of the feed pipe, and then dividing them using a dividing tube and a residual amount release tube. Even if the amount of feed is small, or even if the amount of feed changes, it is possible to uniformly discharge everything from each outlet.
