send to.

The configuration of the seed dispensing box 30 is the same as that in Japanese Utility Model Publication No. 41-5141, so illustration and description thereof will be omitted.

41 is a soil-covering hopper mounted on a support stand 42 on the machine frame;
A thick conduit 43 connected to the outlet is inserted into the upper opening of the soil-covering chamber 29 of the hole puncher, and a steel shaft 45 is fixed to the shaft end of a screw set feeder 44 provided at the bottom. By hooking a chino 47 onto the steel shaft 46 and intermittently rotating the feeder 44 using the drive shaft 10 as a power source, the soil or rice husk E placed in the soil covering hopper 41 is fed out little by little into the soil covering chamber 29 of the hole puncher. Send it in.

The toothless steel shaft 46 has a tooth profile only on a part of its periphery, and the power of the drive shaft 10 is transmitted only when the tooth profile meshes with the chino 47, and this time is used to send it to the seed drilling machine. The time when the puncher 20 is closed is determined according to the timing.

The first embodiment of the present invention has the above-mentioned configuration, and when the machine frame 6 is connected to the agricultural vehicle and the machine frame 6 is moved, the grounding wheel 8 rotates together with the steel shaft 12, and the drive shaft 10 that receives this rotation is powered by the The crank plate 18, the steel shaft 30, and the toothless steel shaft 46, which are coaxial with each other, are rotated.

When the crank plate 18 rotates in the direction of arrow A, the connecting rod 19
The lifting rod 17 is vertically raised and lowered by the guide 16, and the hole puncher 20 is vertically raised and lowered with a constant lift.

When the borer 20 descends, the movable body 22 is closed, and at the end of its descent, the tip of the arm rod 31 passes the water wheel 32 (with the borer closed), and the borer 20 closes. When it descends to its lowest point, the flat bottom 24 of the lower edge is pressed against the ground G to make a shallow hole H.

When the borer starts to rise, the tip of the arm rod 31 gets caught on the waterwheel 32, and in this case, the waterwheel cannot rotate, so the borer 2
0 rises, the tip of the arm rod is pushed down, and as a result, the movable body 22 is separated from the fixed body 21 and the punch 20 is opened.

A few seeds and a small amount of covering soil E have already been fed into the hole puncher 20, and the covering soil E stored at the lower end of the soil covering chamber 29 and the seeds E stored at the lower end of the seed chamber 29 are arranged one above the other. Therefore, when the hole puncher 20 opens, the seeds and the covering soil E slide down from the sloping tube bottoms 25 and 27 and enter the hole H in an overlapping state, and the covering soil E is placed inside the hole. The seeds are covered, and the grounding wheel 8 passes over them to make them flat.

The seed dispensing box 34 uses the drive shaft 10 as a power source to rotate an internal recessed roll, thereby dispensing seeds one by one from the seed box 35 and placing them on the bottom cover.

When the tip of the arm rod 26 passes through the water wheel 27, the hole puncher 20 joins the movable body 22 to the fixed body 21 and closes, and thereafter continues to close until it makes one reciprocation and starts to rise again. .

After the hole punch 20 finishes closing, until it descends to its lowest point, for example, during the descent of the hole punch, the seed dispensing box 34 opens the bottom cover and drops the seeds, and the seeds are sent to the hole punch through the conduit 36. The seeds are placed in the lower end of the seed chamber 30.

The soil-covering hopper 41 rotates the feeder 44 intermittently by a toothless steel shaft 46 on the drive shaft, and the feeder 44 is rotated intermittently when the hole puncher 20 is closed, for example, while the hole puncher is lowering in accordance with the feeding of seeds. is rotated to feed out the covering soil and rice husk in the hopper, which is sent to the hole puncher 20 through the conduit 43 and stored in the soil covering chamber 29 directly above the seed chamber 30.

In this way, when the borer 20 descends to its lowest point, a small amount of covering soil E and several grains of seeds are placed above and below the bottom of the borer, and the borer 20 rises. When the movable body 22 is opened for the first time, the soil covering E and the seedling are each placed at the tube bottom 27.
．． 25, and they fall one on top of the other into the hole H drilled by the hole punch when it descends to its lowest point.

Note that the pitch of sowing, that is, the interval of holes drilled in the ground, can be changed by replacing the steel shaft 12 attached to the ground wheel.

In the second embodiment shown in FIG. 3, a sharp or serrated cutting edge 20a is provided on the entire circumference of the lower edge of the hole puncher 20, and the hole puncher 20 with such a cutting edge is suitable for use in mulch cultivation. Since the film can be perforated, holes can be removed from the film to make shallow holes in the ground, and seeds and cover soil can be dropped into these holes, making it a suitable seeding machine for mulch cultivation.

The above describes two embodiments of the present invention, and the present invention is not limited to these embodiments, and the design can be changed within the gist of the idea.

According to the present invention, a half-split hole puncher, a seeding machine, and a covering soil feeder are mounted on a machine frame connected to an agricultural vehicle, and a soil covering chamber and a seed chamber are placed vertically close to the bottom of the puncher. Seeds and covering soil are fed into the hole puncher by raising, lowering and opening/closing the hole puncher, so the seeds and covering soil are dropped into a shallow hole drilled in the ground as the machine frame advances. This has the effect of efficiently sowing seeds such as Chinese cabbage and radish, which are sown shallowly and covered with soil.

In addition, a sloping tube bottom and a partition wall along the lower half of the sloping tube bottom were installed on the fixed body of the hole puncher, and a tube bottom was installed on the movable body that rose slightly at the lower end and then sloped, allowing the hole punch to close. When the tube bottom and partition wall are closed to form a soil covering chamber and a seed chamber, it is possible to easily create a soil covering chamber and a seed chamber close to each other at the bottom of the hole puncher. The seeds slide down the sloping bottom of the tube, making it suitable for dropping them into the hole one above the other.

Next, a hole puncher with a cutting edge on the lower edge can make holes in the film, so it has the effect of making holes, sowing, and covering soil more efficient even in mulch cultivation.
