  However, in a conventional direct sowing work machine, a plurality of seed sowing tubes for sowing seeds are provided over the entire width of the work machine, but the work width is not varied. In the prior art 1, there is a description of “a configuration that can be folded by the joint portions 24 and 25 provided on the extended boom 17”, but this folding is a configuration that can be folded during “transport and storage”. It cannot be folded during work. For this reason, depending on the size and shape of the field, there has been a problem that the seeding portion overlaps and seeds twice.

  And when making it the structure which makes the right-and-left side part of a direct sowing work machine fold, the position of the seed tank and the structure of several seed sowing pipes were a subject.

  Furthermore, when the traveling speed of the direct sowing machine slows down due to slipping of the traveling machine, a constant amount is automatically seeded, so the seeding amount per unit area increases as the speed decreases, and the unit area increases as the speed increases. There was a problem that the amount of seeding per hit decreased.

In order to solve the above problems, it is a direct sowing work machine that can be mounted on a traveling machine,
Central working body, left and right side working bodies that are extended to the left and right of the central working body and can be folded with respect to the central working body, and seeds can be sown behind the central working body and the left and right side working bodies A seeding device,

Unfolding direct sowing work performed by the central working body and the unfolded left and right side working bodies, single folding direct sowing work performed by folding one of the left and right side working bodies, and folding both left and right side working bodies. The present invention proposes a folding direct sowing machine characterized in that direct sowing work is possible by selecting either of the double-fold direct sowing work.

  In addition, the seeding device includes a seed tank disposed above the central working body, a plurality of transfer pipes from the seed tank to the rear position of the central leveling plate and the left and right side leveling plates at the seeding position, and a seed tank. Propose a folding direct sowing machine as described in column 0008, which is a seeding device in which each of the transfer pipes is provided with a seed feeding section for feeding seeds, and the transfer pipe reaching the rear position of the left and right side leveling plates can be folded. .

  In addition, the seeding device transfers seeds to the rear position of the side leveling plate of the folded side work body when either the left or right side work body is folded. The folding direct sowing work machine described in the 0008 column or the 0009 column, which is a seed feeding unit in which the seed feeding to the transfer pipe is automatically stopped, is proposed.

  Furthermore, the sowing apparatus is a sowing apparatus that automatically controls the amount of seed to be fed out by changing the rotation speed of the seed feeding unit in response to a change in the traveling speed of the traveling machine via the control device. Or the folding direct sowing work machine of the 0009 column or the 0010 column is proposed.

  According to the present invention, the unfolding direct sowing work performed by the left and right side working bodies deployed while being a direct sowing work machine, the single-fold direct sowing work performed by folding one of the left and right side working bodies, and both the left and right sides Since direct sowing work can be selected by selecting either double-fold direct sowing work performed by folding the part work body, it is possible to avoid duplication of direct sowing parts according to the size and shape of the field, and there is a wider work width It became possible to keep the work machine narrow when moving or storing.

  Further, when the side working body is folded, the seed tank of the seeding device is disposed above the central working body, so that even when folded, the weight movement of the seeding device is minimized, so that the balance is good. When the side working body is folded, the seed feeding part for feeding seeds to the transfer pipe is automatically stopped, so that the sowing width is changed, so that it is not necessary for the operator to descend and operate.

  Furthermore, since the direct seeding device can automatically control the amount of seeds fed out by the control device in accordance with the traveling speed of the traveling machine, the seeds that are automatically seeded when the traveling machine speed becomes slow. By reducing the amount and increasing the speed as the speed increases, there is an effect that the seeding amount per unit area can be automatically made constant regardless of the traveling speed by increasing the seed amount sowed proportionally.

  Next, the operation of the folding direct sowing machine according to the embodiment of the present invention will be described. The left and right side work machines 2L and 2R can be folded and unfolded independently by a drive device or manually around the folding rotation shaft 50. In the state where the left and right side work machines 2L and 2R are deployed as shown in FIGS. 1 to 3, the open seeding part 310a, which is the downstream end part of the central transfer pipe 31a, and the downstream end of the left and right side transfer pipes 31b The opening sowing part 310b which is a part is opened in the rear part of the center leveling board 11 and the left-right side leveling board 21 at equal intervals on the left and right sides, respectively.

  In this state, when the vehicle starts to be pulled by a tractor or the like, when the operation switch of the seeding device 3 is turned ON, the feeding motor 32d of the seed feeding unit 32 is activated, and the blower 33a of the blowing device 33 is activated. When the feeding motor 32d is actuated, the rotating shaft 32a rotates and puts seeds S into a number of grooves 32c on the surface of the cylindrical body 32b and rotates to feed them from the seed tank 30 to the transfer pipe 31. The seeding amount for a constant traveling speed is set in advance by the seeding amount adjustment dial 36.

  When the blower 33a of the blower 33 is operated, the blower duct 33b blows air into the six transfer pipes 31, and the seeds in the transfer pipes 31 having different lengths are also uniformly transferred in the transfer pipe 31. For example, the seeding amount is substantially uniform also in the outermost transfer pipe 31b of the central transfer pipe 31a and the left and right side transfer pipes 31b.

  The speed sensor 35a senses the speed (time interval) at which the traveling wheels 35 are rotated by the traveling of the folding work machine and the rod-shaped bodies 35d provided at equal intervals pass through. For example, when the tractor slips in the field and the traveling speed decreases, the passing speed decreases, and the signal is transmitted to the control device 34. Then, the control device 34 automatically reduces the rotation speed of the feeding motor 32 a of the seed feeding unit 32 to reduce the amount of seeds sent to the transfer pipe 31. On the contrary, if the speed sensor 35a sends a signal indicating that the speed has increased to the control device 34, the rotational speed of the feeding motor 32a is increased to increase the amount of seeds sent to the transfer pipe 31.

  Further, when both or one of the left and right side work bodies 2L and 2R are folded, the folded cutting switch 32b on the folded side is turned OFF, and the feeding motor 32a is automatically stopped. Therefore, when one of the side work bodies 2L, 2R is automatically folded during the work, the feeding of the seed S to the side transfer pipe 31b is automatically stopped.

  Further, when the left and right side work bodies 2L, 2R are folded, the side transfer pipe 31b is provided with a rotating part 31c immediately below the seed feeding part 32, and the rotating part 31c causes the rotating part 31c to Since the upstream side and the downstream side rotate, the side transfer pipe 31b that opens to the rear position of the side leveling plate 21 prevents the side transfer pipe 31b that is easily folded by the rotating part 31c from being damaged.

  The present invention is used for an operation of directly sowing seeds such as pods on a field by attaching to a traveling machine such as a tractor.
