Description

  The present invention relates to a seed pod feeder for supplying seed pods to a seed tank or the like of a potato planter.

Conventionally, there are several methods for supplying seed pods to a potato planter seed tank.
First, as a general method, first, seed pods are put in a plastic box called a minicomputer and transported to a farm by a truck. Next, the truck is stopped at the time of farming, and the seed tank of the potato planter is moved back and moved closer to the side of the truck. After that, the minicomputer loaded on the truck bed is manually transported to the seed tank, and the seed pods in the minicomputer are transferred to the seed tank.
Each minicomputer above contains about 25-30kg of seed pods, and it is necessary to move 400-480 minicomputers in one day in order to sow an average of 6 ha per day with a 4 potato planter. become.

  In the second method, seeds are first put in a cloth bag called a 500 kg pack and transported to the field by truck, and then lifted onto the seed tank of the potato planter by a truck crane, and the seed tank is discharged from the discharge port under the pack. The seeds are transferred inside.

In addition, as a third method, the seed pod supply machine described in Patent Document 1 can be used for supplying seed pods to the seed tank of the potato planter.
This seed vase feeder is loaded on the truck bed, and a discharge port is provided in the narrowed part of the pyramid meter tank, a conveyor is placed under it, and the seed vase in the tank is transferred to the seed tank by the conveyor. It can be transferred (Patent Document 1).

In the first method, as described above, it is necessary to carry 400 to 480 minicomputers per day from the truck bed to the seed tank, which is a heavy labor.
Furthermore, potato planters are generally equipped with a fertilizer applicator. When supplying seed potatoes to the seed tank at the headland, it is also necessary to supply fertilizer to the fertilizer tank at the same time. Must be done.

  In the second method, the operation of the truck crane for sequentially moving the pack directly above a plurality of seed tanks (two seed tanks in the case of 2 kg and four seed tanks in the case of 4 kg) is performed. There is a problem that it is cumbersome and requires a person who supports the swinging pack by hand. Also, it must be a truck with a crane, and not all farmers own a truck with a crane.

  In the third method using the soot feeder, etc., in order to prevent the soot from bridging in the tank, the inner surface of the tank is inclined by 60 ° or more from the horizontal plane. For this reason, the ratio of the actual volume of the tank that can actually store the seed potatoes to the external volume occupied by the tank on the truck bed is about 60 to 75%.

On the other hand, with respect to fertilizers, recently, work forms using fertilizer distributors (Patent Documents 2 and 3) have become mainstream, instead of using 20 kg bags and 500 kg packs of fertilizers.
At present, a general farmer loads fertilizer and seeds on a 4-ton truck and transports them to the field. At that time, the farmer loads half a day of fertilizer and seeds on the truck because of work efficiency. preferable.

However, when an existing fertilizer distributor is placed on a 4-ton truck bed, the remaining area of the bed is limited, so that the bottom area of the feeder for seeds and the like is limited.
Also, regarding the height of the feeder for seeds, if the tank position is too high, the seeds contained in the iron container and 500 kg pack cannot be transferred to the tank by a forklift, etc. Driving is dangerous (the road to the farm field is often not paved, and the road to the farm field with a slope also tilts).

For the above reasons, there is a certain limitation on the tank external volume (bottom area x height) of the feeder for seeds and so on. However, if the tank has a pyramid shape, the actual volume that can store the seeds is small relative to the external volume. Thus, half a day's worth of seeds cannot be loaded.
Further, it is desirable that seed tanks can be efficiently supplied to the four seed tanks of a four pot potato planter with a feeder having a simple configuration of one tank and one conveyor without dividing the tank into a plurality of tanks.

  Therefore, an object of the present invention is to provide a feeder for seeds and the like having a tank on which a sufficient amount of seeds can be loaded by increasing the actual volume with respect to the appearance volume. It is another object of the present invention to provide a seed pod feeder that can efficiently supply seed potatoes to a plurality of seed tanks of a potato planter.
