Description

Description: TECHNICAL FIELD The present invention relates to a seeding machine in mulching cultivation, and more specifically, to allow the seeding holes to be formed at the same time as opening the seeding holes in the mulch film covering the ridges so that the seeding holes can be formed. The present invention relates to a seeding machine in multi-cultivation that can surely seed without misalignment even if the opening is small.

Conventional technology Recently, multi-cultivation in which ridges are covered with multi-film has become widespread for making vegetables such as Japanese radish and lettuce, but if a perforated film with pre-seeded holes is used as the multi-film, flat ridges will be used. In this case, the film shift is relatively small, so if the seeding holes are made larger, it is possible to mechanically detect the position of the seeding holes and seed, but the seeding holes that are larger Water is diverged from the soil to maintain proper soil water content, and weeds and the like grow around seeds. Further, in the case of high ridges, the position of the seeding holes preliminarily drilled so that the film easily shifts to the left and right does not necessarily match the top of the ridges, and it is not possible to seed at a predetermined position, so it is not possible to use a perforated film. Can not. On the other hand, the sowing time is determined by predicting the market conditions of the crop and considering the shipping time, so it does not always coincide with the time when the ridges are covered with mulch film, and proper soil moisture is maintained as it is until the sowing time. It is desirable to use a non-perforated film also in order to keep it. However, when the ridges are coated with a non-porous film, the seeding holes must be formed when seeding, and thus, conventionally, the seeding holes are manually opened, and then the seeding work is performed. However, even though it is possible to sow in a predetermined position, there is a drawback that the work is troublesome and inefficient.

Problems to be Solved by the Present Invention The present invention has been made in view of the above circumstances and was devised in order to solve the conventional drawbacks.
A non-perforated mulch film covered with ridges is sown at the same time as seeding holes are sown so that the seeds of vegetables can be sown. The size of the seeds should be small so that proper soil water content can be retained even after sowing, and weeds can be prevented from growing around the seeds to promote the growth of crops and thus to exert the effect of mulching cultivation sufficiently. There is an attempt to provide a seeder that can

Means for Solving the Problems In order to solve the above-mentioned problems, the technical means adopted by the present invention is a sowing machine adapted to sow from a sowing hole formed in the mulch film, in the traveling direction of the machine body. A piercing tool that cuts the mulch film while immersing in the soil and rotating forward is formed with a wedge-shaped heating element, and a seed feeding device is attached to the piercing tool to form a sowing hole. Simultaneously with this, it is configured to sow from a seed outlet provided on the back side of the punch.

Therefore, according to the present invention, when seeding vegetables is sown on the ridges covered with the mulch film, if the machine body is run along the ridges, the punching tool formed by the wedge-shaped heating element advances. The mulch film is sunk into the soil of the ridge in the direction and is rotated forward to form a seeding hole at a predetermined position. Since the feeding device provided in the punching tool feeds the seeds from the seed outlet provided on the back side of the punching tool, the seeding hole can be drilled at the same time, and the seeding hole can be surely seeded without being displaced. Therefore, the sowing work can be performed efficiently, moreover, the sowing holes can be made as small as possible to maintain proper soil moisture even after sowing, and weeds etc. can be kept from growing around the seeds. Can be prevented.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It is rotatable around the axis. Then, as the aircraft advances, as shown by arrow A in FIG. 5, the tip end side is immersed in the soil of the ridge toward the traveling direction of the aircraft, and the mulch film 3 covering the ridge is melted and blown while rotating forward and sowing holes. To drill.
Reference numeral 4 denotes a guide passage for the seed a which penetrates the inside of the perforation tool 1 in the longitudinal direction, and the seed outlet 5 of the guide passage 4 is opened to the rear surface side of the tip of the perforation tool 1 formed in a wedge shape. The seed inlet 6 is open to the side surface of the base end of the punch 1.

Reference numeral 7 denotes a seed a feeding device provided alongside the perforating tool 1, and a feeding roll 10 that rotates in conjunction with the traveling of the machine is pivotally supported by a seed outlet 9 that is opened at the lower end of the seed tank 8. . Reference numeral 11 is a seed hole formed on the outer peripheral surface of the payout roll 10. When the payout roll 10 rotates and the seed hole 11 reaches the upper position, a predetermined amount of seed a is fed from the seed tank 8 into the seed hole 11. Inflow. Reference numeral 12 denotes a roll receiver that is in sliding contact with the pay-out roll 10 from below. In the roll receiver 12, an inlet 13 is opened toward the pay-out roll 10 side, and an outlet 14 is opened toward a side surface of a base end portion of the punch 1. When the feeding roll 10 rotates and the seed hole 11 reaches the lower position, the seed a held in the seed hole 11 flows into the communication passage 15 from the inlet 13. . Then, when the punching tool 1 rotates downward as the machine body travels to open the seeding holes b in the mulch film 3 and sink into the soil, the seed inlet 6 of the guide passage 4 formed in the punching tool 1 is , The seed a which is in communication with the outlet 14 of the communication passage 15 and flows down from the communication passage 15 flows out from the seed outlet 5 through the guide passage 4 and is formed into a groove C formed at the rear of the punching tool 1.
It is supposed to be sown. 16 is a heat insulating material provided on the inner peripheral surface of the guide passage 4, 17 is a power battery for heating the perforation tool 1 to about 120 ° C. or higher, which is the melting temperature of the mulch film 3, 18 is a terminal, and 19 is a conducting wire.

In the configuration as described above, when sowing small seeds of root vegetables such as Japanese radish and vegetables such as lettuce into the ridges coated with the anhydrous mulch film, first, the seed a is filled in the seed tank 8. Then, if the aircraft is then run along the ridge, the payout roll 10 will rotate in conjunction with the running of the aircraft,
The seed a that has flowed in from the seed tank 8 when the seed hole 11 has reached the upper position flows into the communication passage 15 from the inlet 13 when the seed hole 11 rotates to the lower position. On the other hand, when the punching tool 1 heated by the electric current from the battery 18 rotates in the direction of arrow A as shown in FIG. 5 to melt the mulch film 3 and immerse in the soil while opening the seeding hole b, the guide passage Since the seed inlet 6 of 4 communicates with the outlet 14 of the communication passage 15, the seed a in the communication passage 15 flows down the guide passage 4 through the seed inlet 6 and flows out from the seed outlet 5. Therefore, at the same time that the drilling tool 1 drills the seeding hole b, the drilling tool 1 is seeded in the trench C formed by being immersed in the soil. It is not necessary to sow, and sowing work can be performed efficiently.

Further, since the seeding hole b is formed by rotating the wedge-shaped punching tool 1, the opening width required for germination can be secured at the lowest position of the rotation path of the punching tool 1 as shown in FIG. However, the front and rear end portions are formed in a substantially rhombic area with a reduced area to reduce the divergence of water from the sowing holes b to maintain proper soil water content, and the weeds around the seeds. It is possible to prevent overgrowth of plants and the like and promote the growth of crops. Moreover, since the seed outlet 5 is open to the rear surface side of the tip of the perforation tool 1, even if the seed feeding device 7 is installed side by side with the perforation tool 1 immersed in the soil, the groove C
The seed outlet 5 opening toward the bottom does not become clogged with soil, and the seeding work can be performed smoothly.

The seeding machine of the present invention is convenient because it can be used as it is as a fertilizer applicator if the seed tank is filled with granular fertilizer instead of seeds.

EFFECTS OF THE INVENTION In short, the present invention, in a seeding machine that seeds from a seeding hole formed in the mulch film, cuts the mulch film while immersing in the soil toward the traveling direction of the machine body and rotating forward. The piercing tool is formed of a wedge-shaped heating element, and a seed feeding device is provided along with the piercing tool, so that the seeding holes are formed at the same time as seeding is performed from the seed outlet provided on the back side of the piercing tool. In order to maintain proper soil moisture until the sowing time, even if the ridges are covered with anhydrous mulch film, the perforation tool formed by the wedge-shaped heating element is Since the seeding hole is formed by immersing in the ground and rotating forward, it is not necessary to separately form the seeding hole as in the conventional case, and the seeding work can be made efficient. Moreover, the wedge-shaped perforator only rotates forward, and at the same time when the seeding hole is drilled, the seed feeding device attached to the perforator taps the seed from the seed outlet provided on the back side of the perforator. It is possible to sow without being displaced from the provided sowing holes. Therefore, the sowing hole can be formed as small as possible with a wedge-shaped perforating tool, the divergence of water from the sowing hole can be reduced even after sowing, and proper soil water content can be maintained, and at the periphery of the seed. It is possible to prevent overgrowth of weeds and the like and to promote the growth of crops.
