Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transplanter for transplanting seedlings of plants such as soybeans, adzuki beans, and various satsatsu vegetables grown in a nursery into the soil of a field.

In general, if the above-mentioned vegetables are cultivated by sowing seeds directly in fields, etc., there are many problems such as being eaten by harmful birds during the time after sowing until the seeds sprout or before the seedlings reach a certain size. has a major impact on the harvest.

For this reason, in recent years attempts have been made to grow various vegetables such as soybeans and adzuki beans in nurseries, and after the seedlings have grown to a certain extent, they are transplanted to fields for cultivation.

By the way, conventional seedbeds for transplanting have been made by filling paper pots and the like with the bed, but these are made by hand one by one, and at the time of transplanting, the bed with seedlings is pulled out from inside the paper pot by hand. It is very troublesome and time-consuming, and the work efficiency is low.Also, even if you carefully and carefully remove the bed soil from the paper pot, the bed soil will collapse and cause damage to the seedlings. The roots are often damaged or cut, which impedes root growth and causes poor rooting in the transplant site, resulting in problems such as the plant's growth and harvest not being as expected.

Therefore, in order to solve the above-mentioned conventional problems, the present applicant has recently developed an agricultural machine for manufacturing a transplanting seedbed 1 as shown in FIG. 1. This is done by putting the floor material adjusted to a predetermined moisture content into a hopper, sending out the bed material from the hopper, and automatically compressing it into a predetermined amount one after another into a rectangular prism shape to create a floor of ±2. A pair of left and right sheets of resin film, etc. 3.
The left and right sheets 3, 3 cover the circumferential side of each floor 2 from the left and right with one diagonal line as the border, and the left and right sheets 1 to 3 are fed in a line between the two floors. 3.3
They are sewn together 4 by heat welding or the like to form the transplant seedbed 1.
It is a configuration that creates With this, it is possible to automatically create a large number of seedbeds 1 one after another in a chain shape without relying on much manual labor, and if such a seedbed 1 is used, it can be conveniently stored in a nursery box or the like and the desired plant seeds can be grown. You can grow seedlings 5 by sowing the seedlings 5, and once the seedlings 5 have grown to a certain extent, peel off the sheet 3.3 that covers the sides of each seedling bed 1 twice from side to side to avoid damaging the roots of the seedlings 5. Not only will it be possible to improve the workability of producing seedbeds by allowing them to be transplanted into fields without any problems, but it will also be effective for plant growth, and a significant increase in yield can be expected.

However, no transplanting machine has been developed that transplants the seedlings 5 to the soil of a field after sowing them in the seedbed 1 manufactured by the above-mentioned transplanting seedbed manufacturing machine and growing them to a certain size. Numerous seedbeds stored in boxes 1...
・It is inefficient and wide to manually pull out the floor ±2 by peeling off the left and right sheet 3. There is a problem in that it takes a lot of effort and time when transplanting a large number of plants onto a large field.

The present invention was made in view of the above circumstances, and its purpose is to use the above-mentioned transplanting seedbed manufacturing machine to sow seeds of desired plants in the prepared seedbed and grow them into seedlings of a certain size. It is very easy to transplant the plants in the field to the field, and it is very simple and efficient because they can be automatically planted one by one in the soil of the field without the need for any human hands. The purpose of this invention is to provide a highly practical transplant machine.

In other words, the transplanting machine of the present invention covers a large number of pillar-shaped floors from both sides with a pair of left and right sheets of resin film, etc., and sews the left and right sheets to each other on each floor by heat welding or other means.
