Description

  The present invention relates to a transplanter for, for example, transplanting onion seedlings reciprocally two rows at a time for four rows.

  Conventionally, there has been a transplanter that equips a traveling machine body with two sets of rotary pots for one row and planting and opening devices for two rows, and planting two rows of seedlings at the same time.

JP-A-11-187711

  When the rotary pots are juxtaposed, the interval between the seedling positions from each of the rotary pots to the planting and opening unit is widened. Therefore, simultaneous planting of the first and second lines and the third and fourth adjacent lines from the end is not possible. It is impossible to do this, and simultaneous planting of the first and third lines and the second and fourth lines from the end is performed, but the distance between the adjacent two lines of the first and second lines and the third and fourth lines from the end is stable. Therefore, it is extremely difficult to work with a harvester that simultaneously harvests two adjacent strips. In addition, there is a problem that the seedling supply position to each rotary pot is far from the worker, and it is difficult to cope with short-plant transplantation or high-speed transplantation, and it is difficult to increase work efficiency.

To solve the above problems, the present invention is as follows.
That is, in the first invention, the vehicle is supported by the four left and right front wheels 4, 4 and the left and right rear wheels 5, 5, and the steering hand engine 1 and the traveling transmission case 2 are mounted. A four-wheel walking type airframe having an airframe frame 3 and a steering handle 6 at the rear is configured, and runs along a ridge 8 on which four onion seedlings 7 are planted with four wheels 4 and 5. The link plates 22 are fitted to the lower portions of the seedling pots 10 of the seedling supply unit 9, the link plates 22 are connected by connecting pins 23, and the link plates 22 are connected to the link plates 22 via fulcrum pins 32. The valve body 30 is pivotally supported so as to be openable and closable to form a pot continuous body 24 formed by connecting a large number of seedling pots 10 endlessly, and is driven by a drive shaft 25 which stands vertically inside the steering handle 6. Between two parallel vertical axes of axis 27 The pot linked body 24 is stretched in an oblong shape extending in the left-right direction of the machine body so as to project from the upper part of the steering handle 6 to one side thereof via the drive and driven sprockets 28 and 29 which are united. The operator manually puts the seedlings 7 one by one into the large number of cylindrical seedling pots 10 provided in the seedling feeding section 9 of the seedling feeding section 9. The seedlings 7 are automatically dropped from the seedling pots 10 of the seedling supply unit 9 to the planting and opening devices 12 and 13 which are provided side by side at the same interval as the interval between two adjacent lines. The seedling pot 10 containing the seedlings 7 has moved to the seedling supply position above the left and right planting openers 12, 13 in the case where two adjacent rows are simultaneously planted by the hole punches 12, 13. At the time, the two seedling pots 10 At a pitch at which two empty seedling pots 10 are arranged between 10, the pot link 24 connects a large number of seedling pots 10 so that the empty seedling pots 10 do not move to the seedling supply position. In addition to the above configuration, one section provided on the covering section 14 below the rear of the fuselage is covered by two pairs of covering rings 15 and 16 to cover and suppress the seedlings 7 planted in the ridges 8. It is characterized in that it is made to be performed.

  According to a second aspect of the present invention, two adjacent streaks are simultaneously planted by the left and right planting apertures 12 and 13, and further provided on the soil covering portion 14 below the rear part of the fuselage. Endless connection of a large number of seedling pots 10 in a transplanting machine in which soil covering and suppression of the seedlings 7 planted in the ridges 8 are performed by two pairs of covering rings 15 and 16 with left and right pairs of coverings. And a pot-like body 24 extending in the left-right direction of the machine so that the pot-like body 24 extends from above the control handle 6 to one side of the steering handle 6 via an engaging body between two vertical axes. At the same time, each seedling pot 10 is passed above the left and right planting apertures 12 and 13 of the planting part 11 from the front of the operator located behind the steering handle 6 and is again located behind the steering handle 6. Move back in front of the worker A valve 30 is provided at the bottom of each seedling pot 10, and each valve 30 is moved toward the moving direction of each seedling pot 10 at a position where seedlings are supplied to the planting and opening devices 12 and 13.
