This prevents wear and tear on the shutter 45.

Since it is configured as above, the shutter 45
can be opened and closed independently in each group,
This makes it possible to freely control part or all of the feeding even when the feeding roll 33 is in operation, and especially since it is closed by approaching or supporting the brush 35 as described above, the gap between the feeding rolls 33 If the number of threads is reduced after the thread has been rotated, the possibility of the thread remaining in the thread can be reduced, and mistakes such as when the thread is fed out even after being shot will be eliminated. The brush 35 has a function of scraping the inside of the variable feed groove 34 in addition to its guiding function.

Furthermore, the guide plate 38 that receives the seeds falling from the seed hopper 12 and supplies them to the feed roll 33 is set in a seed supply position, and the guide plate 38 is configured to feed seeds directly to the sowing chute 13 forming the drop opening without feeding the seeds to the feed roll 33. Since the position for taking out seeds can be changed freely, when sowing is completed or when you want to sow seeds of a different type, the dispensing material guide plate 38
Simply change the position of the machine to the seed extraction position.
All of the seeds inside can be taken out, making the work of taking out simple and easy, thereby improving the efficiency of sowing work.

In addition, a gap is required between the outer circumferential surface of the rotatable feed roll 33 and the guide plate 38 whose posture can be changed due to manufacturing reasons, but since this gap is closed by the brush 35, the guide plate Inadvertent dropping of seeds from the gap between 38 and the feed roll 33 can be effectively prevented.

The additional example shown in Fig. 2 is a basic base, for example, a four-row direct sowing machine 11, with extension direct sowing machines 11' attached to both left and right sides, which can be rotated and oscillated as needed. It has been devised so that you can take an evasive stance when faced with it. In other words, 4 direct sowing machine 1
Fixed support plates 54, 54 are erected high at both ends of a mounting bar 53 that is suspended horizontally on the front or rear surface of 1, and an extension bar 56 supported via a fulcrum roller 55 is used to extend two rows each on the left and right sides. The working posture is first completed by pivoting the direct seeding machine 11' and pinning the attachment plate 57 fixed to the extension bar 56 to the fixed support plate 54. The avoidance position is achieved by first raising the roller mast 58 along the fixed support plate 54, then turning inward at an angle of 90 degrees at the upper end and fixing the mounting plate 57. This allows the extended direct sowing machine 11' to be retracted in a very compact manner when it is not needed, and on the other hand, it can be put into a sowing mode very easily when it is needed. In this case, if the turning radius allows, the position of the lower fulcrum roller 5 may be used as a pivot axis, and the ground plate 26 may be raised and lowered freely around the pivot axis. Foldable. Further, the extension feeding shaft 60 is detachable via a joint 61.
