The seedlings are opened in a state and are supplied to the field to be planted, and provided with a powder container (26) that circulates around the seedling planting body (4) in a plan view, the powder container (26) When it comes to a predetermined position, it is configured to receive the powder particles in the seedling planting body (4) and supply it into the soil by descending the seedling planting body, and the seedling inlet at the upper part of the seedling planting body The upper part of (5a) is open.

  At the time of seedling planting work, when the seedling planting body (4) is placed at the top dead center position and a seedling is introduced from the seedling insertion port (5a) above the seedling planting body, the vertical movement mechanism (3) The seedling is lowered to a predetermined position by the operation of, and the seedling that is opened and received at the bottom dead center position is planted in the soil of the field. After planting, it rises, closes, reaches the top dead center position, stops, and waits until the next seedling is introduced.

  The powder container (26) rotates around the seedling planting body (4) located at the center, and when it reaches a predetermined position, the outlet opens to lift the powder body in the container (26). It is received at the bottom of the seedling planting body waiting at the dead center position. And the granular material received by the fall of a seedling planting body is supplied to the downward direction of the seedling planted in soil.

  In short, according to the present invention, without changing the structure of the seedling planting body, the powder body can be received in the lower part of the seedling planting body with a simple structure. Can be supplied to the soil first, i.e., the granular material can be supplied below the seedling to be planted. If this granular material is a fertilizer, the growth of the seedling can be promoted. In addition, since the upper part of the seedling inlet at the upper part of the seedling planting body is open, seedlings can be easily input, artificial seedling input work can be performed efficiently, and the machine body can be configured compactly.

Embodiments of the present invention will be described with reference to the drawings.

  The seedling transplanter opens and closes up and down in conjunction with a vertical movement mechanism 3 that is driven to move up and down on a machine equipped with a traveling device 1 and a steering handle 2 that travel along the left and right grooves while straddling the ridge U in the field. A seedling feeding hopper that can be planted by a beak-like seedling planting body 4 and that feeds seedlings from the seedling inlet 5a to the upper part of the seedling planting body and guides them into the lower seedling planting body 4 5 is provided.

  In the illustrated example, the traveling device 1 includes a pair of left and right rear wheels 6 and 6 that are driven and rotated by transmission of the power of the engine E, and a pair of left and right front wheels 7 that are rotatably supported in front of the rear wheels 6 and 6. , 7.

  A mission case 8 is disposed at the rear portion of the engine E, and the mission case 8 has a case portion extending from the left side portion to the left side of the engine E, and this is connected to the left side portion of the engine E. The output shaft of the engine E enters the case portion and the power is transmitted to the transmission mechanism in the transmission case 8. A transmission case 9, 9 is rotatably attached to both left and right sides of the transmission case 8, and the tip of a wheel drive shaft 9a is extended from the transmission case 8 to the left and right outer sides at the rotation center of the transmission case 9, 9. Enters the transmission power in the transmission case 9 and the transmission mechanism in the transmission case 9. The driving power is transmitted to the axles 10 and 10 which extend to the rear side of the machine body and protrude to the side of the rear end side via the transmission mechanism in the transmission cases 9 and 9, and the rear wheels 6 and 6 are driven to rotate. It is supposed to be.

  Also, upwardly extending arms 11, 11 are integrally attached to the attachment parts of the transmission cases 9, 9 to the transmission case 8, and this is the tip of the piston rod of the lifting hydraulic cylinder 12 fixed to the transmission case 8. Are connected to the left and right sides of a balance rod 13 that is pivotably mounted around a vertical axis. The right side of the connecting portion is connected by a rod 14, and the left side is connected by a left / right horizontal control hydraulic cylinder 15 which can be expanded and contracted.

  When the lifting / lowering hydraulic cylinder 12 is actuated and the piston rod projects rearward, the left and right arms 11 and 11 are rotated rearward, and accordingly the transmission cases 9 and 9 are rotated downward, and the airframe. Rises. On the contrary, when the piston rod of the elevating hydraulic cylinder 12 is retracted forward, the left and right arms 11 and 11 are rotated forward, and accordingly the transmission cases 9 and 9 are rotated upward so that the aircraft is Descend. The elevating hydraulic cylinder 12 is configured to operate the airframe to be a set height with respect to the height of the heel surface based on the detection result of the sensor S that detects the height of the heel surface with respect to the airframe. It is also configured to operate so as to raise or lower the aircraft by manual operation of an operating tool arranged in the vicinity of the steering handle 2.

  Further, when the left / right horizontal control hydraulic cylinder 15 expands / contracts, the balance rod 13 rotates around the vertical axis connected to the tip of the piston rod of the lifting hydraulic cylinder 12 at the center of the left / right to transmit left / right transmission. Cases 9 and 9 are moved up and down alternately to incline the aircraft from side to side. The left / right horizontal control hydraulic cylinder 15 is configured to operate so that the airframe is horizontally horizontal based on a detection result of a sensor that detects the right / left inclination of the airframe relative to the left / right horizontal.

  The seedling planting vertical movement mechanism 3 is mounted on a planting transmission case 18 that includes a transmission mechanism that receives power for driving a seedling planting body from the mission case 8 and transmits it. As shown in the figure, the planting transmission case 18 includes a first case portion 18a, a second case portion 18b, a third case portion 18c, and the like. A power transmission mechanism for transmitting power for driving the vertical movement mechanism 3 up and down from the first case part 18a to the third case part 18c is provided. In addition, the transmission mechanism housed in the first case portion 18a includes a one-rotation clutch mechanism that stops the seedling planting body 4 at the vertical movement top dead center position. When a seedling is put into the seedling feeding hopper at the top of the seedling planting body, the sensor detects it and sets the clutch to “activate” to operate the one-rotation clutch mechanism, and the seedling planting body descends to a predetermined position to plant the seedling. After being attached, it rises to a predetermined position and stops.

  The seedling planting body 4 is moved up and down via the crank arms 19 and 20 and the swinging arms 21 and 22 of the vertical movement mechanism 3, and as a result, the lower end portion of the seedling planting body 4 is moved up and down in a side view. It moves up and down with a long closed loop trajectory T. In addition, when the beak-shaped seedling planting body 4 is lowered to the lowest position, the beak-like seedling planting body 4 opens back and forth and releases the seedlings in the seedling planting body 4 into the soil of the ridge U. And this seedling planting body closes when it rises, rises to the top, and stops automatically.

Next, the granular material supply apparatus 25 which supplies granular materials, such as a fertilizer and a chemical | medical agent, in the said seedling planting body 4 is demonstrated.
That is, the granular material supply device 25 has a cylindrical body that opens up and down and a bottom lid (not shown) that opens and closes an opening on the lower side of the cylindrical body, and a plurality of powders that are connected in a loop. A granular container moving mechanism for rotating the granular container 26 and the granular granular container 26 around a loop-shaped movement locus in a plan view of the machine body in a state of surrounding the seedling planting body 4. 27 (gear mechanisms 27a, 27b) and a bottom lid opening mechanism (not shown) for opening the bottom lids of the granular material containers 26 at predetermined positions. The gear mechanisms 27a and 27b are intermittently driven by the drive shaft 23 taken out from the planting transmission case 18a.

  At a predetermined position of the orbital movement trajectory of the powder container 26, the powder from the powder container that has reached this predetermined position is received and supplied to the inside of the seedling planting body 4. The body supply rod 28 is provided. The upper end opening portion 28a of the granular material supply rod 28 faces below the lower end opening portion of the granular material container 26 that has reached a predetermined position, and the lower end opening portion 28b is located on the lower end side of the seedling planting body 4. It faces the upper part of the granular material receiving funnel 30 provided in communication.

  A powder storage tank 31 is installed on the front side of the powder supply device 25 on the upper side thereof, and reaches a predetermined position (powder supply position) via the powder supply unit 32. A configuration is adopted in which a predetermined amount is fed and supplied into the granular material container 26.

  The upper part of the seedling input port 5a of the seedling planting body is open, and the upper end of the seedling input hopper 5 is made higher than the upper end of the granular material container, so that it is easy to manually input the seedling into the hopper 5. I can do it.

  The seedling transplanter operates as follows. The aircraft is self-propelled by the traveling device 1 straddling U. When the seedling planting body 4 is placed at the top dead center position and a seedling is introduced from the seedling inlet 5a above the seedling planting body, the seedling planting body 4 is lowered to a predetermined position by the operation of the vertical movement mechanism 3, and the bottom dead center position. Plant the seedlings opened and accepted in the soil in the field. After planting, the seedling planting body rises and closes, reaches the top dead center position, stops, and waits until the next seedling is introduced.

  When the granular material container 26 rotates around the seedling planting body 4 located at the center and reaches a predetermined position corresponding to the upper end opening 28a of the granular material supply rod 28, the bottom lid is opened and accommodated. The granular material in the body is received in the supply basket 28 and supplied to the lower part of the seedling planting body waiting at the top dead center position through the supply basket and the granular material receiving funnel 30. And, in this state where the granular material is received in the seedling planting body 4, when the seedling is introduced into the upper part of the seedling planting body, the seedling planting body is lowered and opened to a predetermined position in the soil, The granular material in the seedling planting body is supplied before the seedling, and the seedling is planted on the supplied granular material. In addition, after transplanting, the root side of the seedling planted by the pressure ring 33 is suppressed.

  As described above, when not using one seedling planting body, as shown in FIG. 3, the seedling feeding hopper 5 is lowered below the turntable 34, and the supply rod 28 is raised so that a turntable type seedling transplanting machine is used. It can also be used as

Further, if the seedling hopper 5 is configured in a bellows type, the height can be freely changed.
Next, the embodiment shown in FIGS. 4 and 5 will be described.

In the seedling transplanting machine, the front turntable Th is arranged at the center of the machine body, and the rear turntable Tn is offset to the right side so that the seedling can be easily supplied. The inner diameter of the powder body container 26 is small, and the seedling container 35 is larger than that so that the seedling can be easily supplied.

  If the bottom cover of the powder container 26 is opened before the bottom cover of the seedling container 35 in a timely manner, the powder will surely enter under the seedling. Conversely, the bottom cover of the seedling container can be configured to open before that of the powder container, and according to this, the powder is supplied onto the seedling. .

  The drive chains 36, 36 of the turntables Th, Tn are arranged below them so as to avoid the powder body container 26 and the seedling body body 35, and are driven from a drive shaft 23 protruding from the planting transmission case 18a. It has become so. A seedling stand 37 is provided on the upper right half of the rear turntable Tn, and an auxiliary seedling frame 38 is provided on the front side of the front turntable Th.

  In the embodiment shown in FIG. 6 and FIG. 7, in the turntables Th and Tn arranged at the front and rear, the front turntable Th is down and the rear turntable Tn is up and back and superposed, and The superposition | polymerization part is arrange | positioned so that it may overlap in the center upper part of the seedling planting body 4. FIG. The diameters of the front and rear containers 26 and 35 are the same, and the seedlings put in the rear fall simultaneously into the seedling feeding hopper 5 above the seedling planting body with the fertilizer put in the front down. The overlap of the front and rear turntables can be reversed (the front table Th is up and the rear table Tn is down). In this case, fertilizer can be supplied onto the seedlings.

If the seedling container 35 of the rear table Tn is configured so that the height in the vertical direction can be changed, it can be conveniently adjusted according to the seedling height.
Further, the front and rear turn tables Th and Tn can be arranged in an overlapping state as shown in FIG. In this case, the table may be rotated clockwise in the front and counterclockwise in the rear so that the fertilizer and the seedling are supplied into the seedling hopper above the seedling planting body.

  Moreover, as shown in FIG. 9, the front is a turntable (circular type) powder supply unit Th, and the rear is a rotating sushi type (circular with a loop-like movement trajectory that is non-circular in plan view and long in the horizontal direction) By moving to the seedling supply unit Tn, fertilization and seedling transplantation can be performed simultaneously.
