Description

[Detailed description of the invention] The present invention relates to a towed seedling transplanter, and in particular provides an inexpensive towed seedling transplanter with the simplest structure by using an agricultural moving machine such as a tractor tailor owned by a farmer. The purpose is to

With conventional seedling transplanting machines, it has been impossible to arrange a plurality of seedling transplanting devices in a row in the lateral direction with respect to the seedling transplanting direction.

For example, in the case of the seedling transplanter shown in Figure 9, machine frame 1
A chain gear 2 is attached to the machine frame 1, a chain gear 4 is attached to the rising frame 3 set upright on the machine frame 1, and a chain gear 6 is attached to the horizontal frame 5 fixed to the rising frame 3, and an endless chain is attached to these gears 2, 4, and 6. A plurality of seedling clamp holders 9 each having a seedling clamping rubber 8 are arranged at predetermined intervals, and the left and right pressing wheels 10, 1 are rotatably stretched.
The endless chain 7 is rotated through the transmission device 11 using the drive source 0 as a driving source, and the seedlings 12 are planted.

Since this seedling clamp holder 9 is disposed on the endless chain 7, it can only be provided in a flat configuration, and moves parallel to the direction in which the seedlings 12 are transplanted. In other words, the seedling holder 9 cannot be moved laterally. Normally, the seedling planter should follow the direction of transplantation.
Although the user sits on the seat 13 facing backwards, even if the width of the seedling transplanter 14 configured as described above is smaller than the ridge width, the transplanter's lateral width is larger than the ridge width, making the transplanting work difficult.

In addition, the position where the seedling operator can insert seedlings into the seedling clamp holder 9 is only within a small range A where the seedling clamp rubber 8 rotates downward from the uppermost position where it opens with elasticity, which causes a decrease in work efficiency. There is.

In addition, the seedling transplanter 15 shown in FIG. 10 has an endless chain 21 stretched between the chain gear 17 of the machine frame 16 and the chain gears 19 and 20 provided on the riser frame 18 which is approximately parallel to the machine frame 16. A seedling clamp holder 23 is configured to be tilted laterally on this chain 21 via a pin number 22. However, this type of device has a drawback that, after transplantation, the seedling holder 23 rotates upward while tilting, so that the sapling holder 23 swings against the transplanted seedling, damaging the seedling.

The seedling transplanter 24 shown in FIG. 11 is a special-purpose machine in which a plurality of seedling transplanters 26, 26, . However, the seedling planter must sit on the seats 27, 27, etc. perpendicular to the transplanting direction, and due to the structure, a dedicated transplanter with a special structure such as the drive device such as the engine 28 and the machine frame 25 itself must be manufactured. There are economic problems. Furthermore, due to space considerations, it is not possible to install four or more seedling transplanting devices.

Moreover, one seedling operator is in charge of two seedling transplanting devices, but there are limits to human hand movement.
Whether one person is cutting two seedlings or one person is cutting one seedling, the amount of work will be the same. In other words, one person has 2
The transplanting speed is only halved when using the table, and when two machines are in charge of seedlings, when inserting the seedlings into the outer seedling transplanter, the seedling operator's body may come into contact with the inner seedlings. This has the disadvantage that the seedlings become uneven and the transplanting condition becomes unstable.

In view of the above drawbacks, the present invention aims to provide a towed seedling transplanter that can be easily attached to an agricultural mobile machine. That is, the towed seedling transplanter according to the present invention has a plurality of vertically adjustable devices interposed between the rear end of the pressing roller supported by the machine frame attached to the agricultural moving machine and which can be adjusted up and down by the machine frame and the connecting device. A seedling transplanting device is attached, and a plurality of seats are provided on the upper part of the up-and-down device, and a drive pulley is driven via a transmission device using a suppression wheel as a drive source, a pulley located above the drive pulley, and a fuselage. A tensioning pulley positioned at a predetermined angle to the outside of the aircraft body as viewed from the center is disposed on the machine body, and an endless belt is stretched between the driving pulley, the upper pulley, and the tensioning pulley, The endless belt is stretched at a predetermined angle outward from the center of the machine at least between the upper pulley and the tensioning pulley. The clamping tool is characterized in that it stands up vertically immediately after transplantation.
