Description

TECHNICAL FIELD The present invention relates to a seedling planting machine equipped with a fertilizer application device, and in particular,
The present invention relates to power transmission to a fertilizer application device.

[Conventional technology and its problems]

As a conventional technique of this kind, there is one in which a transmission mechanism for driving a fertilizer feeding device of a fertilizer applicator is provided in addition to a transmission mechanism for vertically moving a seedling plant of a seedling plant, but the transmission mechanism is complicated. However, it was not possible to obtain a small and lightweight seedling planting machine with a fertilizer application system.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides a rotary transmission case 11 which is rotated by a drive shaft 10 provided in the transmission case 9, and the seedlings are taken out from the seedling supply device 3 into the rotary transmission case 11 to produce a field. In the seedling planting machine provided with the seedling planting body 4 to be planted in, the actuating body 27 of the fertilizer feeding device 1 of the fertilizer applying device mounted on the seedling planting machine and the position eccentric from the drive shaft 10 of the rotary transmission case 11 are arranged. This is a seedling planting machine with a fertilizer application characterized in that the fertilizer feeding device 1 is driven by the rotation of the rotary transmission case 11 in a linked manner.

[Effects] The present invention links the actuating body 27 of the fertilizer feeding device 1 of the fertilizer application and the position eccentric from the drive shaft 10 of the rotary transmission case 11 and rotates the rotary transmission case 11 to rotate the fertilizer feeding device. Since it is configured to drive 1 to drive the seedling plant 4
Since the fertilizer feeding device 1 is driven by utilizing the rotation of the rotation transmission case 11 which is the transmission configuration of, the feeding of fertilizer can be performed smoothly, and a small and lightweight seedling planter with a fertilizer application can be obtained. The conventional problem can be solved with a simple structure.

〔Example〕

A riding type rice transplanter according to an embodiment of the present invention will be described in detail with reference to the drawings.

The seedling planting device 6 having the seedling supplying device 3 and the seedling planting body 4 is connected to the rear side of the tractor by an elevating link mechanism 7. Then, on the side of the transmission case 9 to which the float 8 is attached,
A rotary transmission case 11 that is driven to rotate around a lateral drive shaft 10 is provided, and at both ends of the rotary transmission case 11, seedling planting shafts 12 that mount the seedling planting body 4 are rotatably provided. Axis 12
Is rotatably transmitted between the drive shaft 10 and the drive shaft 10 through an eccentric fixed gear 13 that is integral with the transmission case 9 side and does not rotate, and an eccentric intermediate gear 14 that constantly meshes with the eccentric fixed gear 13. The eccentric rotary gear 15 and the like are provided, the eccentric rotary gear 15 is fixed to the seedling planting shaft 12, and the rotary transmission case 11 is integrally rotated with the drive shaft 10, thereby eccentricizing the eccentric intermediate gear 14. The eccentric rotation gear 15 is rotated while revolving around the fixed gear 13 to rotate the eccentric rotation gear 15, and the relative rotation transmission of the seedling plant 4 with respect to the rotation transmission case 11 is performed.

Each seedling plant 4 is constructed integrally with the eccentric rotation shaft 12 and is revolved while maintaining a posture substantially parallel to one rotation of the rotation transmission case 11, and has a needle-like seedling at the tip. Holding needle 1
6, and the seedling pushing claw 1 which is vertically moved along the seedling holding needle 16
It is transmitted and rotated with 7 etc. always facing downward. The seedling pushing claw 17 is provided with a pushing mechanism and is provided with an eccentric cam 19 on a fixed shaft 18 which is located on the outer periphery of the seedling planting shaft 12 and is integral with the rotary transmission case 11, and an outer peripheral surface of the eccentric cam 19 One end of a tribute rod 21 that swings around a pin 20 is slidably contacted with the stud, and the other end of the tribute rod 21 is engaged with the upper end portion of the seedling pushing claw 17 to allow the seedling plant 4 to revolve during its revolution. In the preceding stroke in which the holding needle 16 acts on the seedling take-out portion of the seedling feeding device 3, the seedling pushing claw 17 is placed at the upper position, and the seedling holding needle 16 moves to the lower position at the position where it intervenes in the soil surface, The seedling-holding needle 16 and the seedling-holding needle 16 are operated in such a relationship that the seedling can be planted in the soil.

The transmission structure of the fertilizer feeding device 1 is such that the lower end portion of the rod 23 is rotatably fitted to the outer end portion 22 of the seedling planting shaft 12 of the one seedling planting body 4, and the drive shaft 10 of this seedling planting shaft 12 is rotated. By orbiting around,
This rod 23 can be reciprocally rocked up and down. Fertilizer feeding device 1
Is rotatably attached to the lower end of the fertilizer tank 24, and the upper end of the rod 23 is connected to one end of the roll shaft 26 via an actuating member 27 of the one-way rotating clutch 2 such as a ratchet mechanism. The vertical movement of the rod 23 causes the actuator 27
Is configured to be reciprocally rotated up and down so that the feeding roll 25 can be intermittently rotationally transmitted at a constant rotation angle.

The tractor is provided with an operation handle 29 at the front of the vehicle body 28, a lifting link mechanism 7 at the rear of the cockpit 30 so that it can be lifted and lowered by a telescopic cylinder 31 by hydraulic pressure, and a prime mover under the cockpit 30.
The front wheel 33, the rear wheel 34, and the seedling planting device can be driven by the 32. 35 is fertilizer tank 24, fertilizer feeding device 1
A supporting frame for supporting the fertilizer application device, etc., is detachably mounted on the transmission case 9 constituting the machine body of the seedling planting device. Reference numeral 36 denotes a fertilizer pipe that receives the fertilizer fed from the fertilizer tank 24 by the rotation of the feeding roll 25 and guides it down the soil surface.

Then, in particular, the fertilizer feeding device 1 of the fertilizer feeding device 1 of the fertilizer application is connected to the position eccentric from the drive shaft 10 of the rotary transmission case 11 by rotating the rotary transmission case 11.
Since the fertilizer feeding device 1 is driven by utilizing the transmission structure of the seedling plant 4, it is possible to obtain a small-sized and lightweight seedling planter with a fertilizer application.
Also, since the transmission mechanism of the seedling planting device is hardly changed, it is possible to change from a seedling planter without a fertilizer application device to a seedling planter with a fertilizer application device by an external additional interlocking structure. And two types of seedling planters with fertilizer application can be manufactured at low cost and with high production efficiency.
