Description

[Detailed description of the invention] [Field of industrial application] The present invention has a planting arm that can rotate up and down so that the planting claws equipped with it can take out a unit amount of seedlings from the seedling take-out port and plant them on the mud surface. The present invention relates to a planting device that is provided with a soil gathering device that operates in conjunction with the circulation operation of the planting arm to press and move mud toward the planted seedlings.

[Conventional technology]

In this type of planting device, the soil is pressed and moved toward the planted seedlings by the soil gathering tool, and the planting claws backfill the holes formed in the mud surface and compact the muddy part where the seedlings have been planted. , it is possible to improve the survival of the planted seedlings, stabilize the posture of the planted seedlings, and thereby suppress poor planting as much as possible and improve the planting efficiency. And conventionally,
The soil gathering device was attached to a planting mission case that supported the planting arm, and the soil gathering device was driven by a drive shaft that was provided in a state that interlocked with the planting arm (for example, in 1983).
-90314).

[Problem that the invention attempts to solve]

However, when using conventional means, a dedicated drive shaft is required to drive the mulching tool, so the structure as a whole, including the mounting structure of the drive shaft, is complicated and has a large number of components. Ta. In particular, if multiple planting arms are configured to be able to be driven and stopped individually in order to enable ridge planting, the soil gathering tools that correspond to each planting arm are also driven and stopped separately. It is necessary to freely configure the structure, and as a result, a clutch is required for each of the earth movers, making the structure extremely complicated.

The present invention has been developed with this point in mind, and its purpose is to simplify the structure.

[Means for solving problems]

The characteristic configuration of the planting device according to the present invention, which was taken to achieve the above object, is that the soil gathering tool is attached to the planting arm, and the soil gathering tool is linked to the drive crankshaft of the planting arm. The effects of this are as follows.

[Effect]

Since the soil gathering tool is attached to the planting arm and linked to the drive crankshaft of the planting arm, there is no need for a special drive shaft to drive the soil gathering tool in conjunction with the planting arm. The mechanism that interlocks the two can be of simple structure. Moreover, when the planting arm is deactivated,
Since the mulching tool attached to the planting arm is also deactivated, there is no need for a special clutch for deactivating the mulching tool that corresponds to the deactivated planting arm.

[Effect of idea]

Therefore, it has become possible to provide a planting device that has a simple structure and is particularly useful when a plurality of planting arms are configured to be able to be driven and stopped individually.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 3, a link mechanism 3 that is driven up and down via a cylinder 3A is connected to the rear of a passenger vehicle 2 equipped with a driver's seat 1.
A multi-row planting device 4 is attached to the rear end of the rice transplanter to constitute a riding rice transplanter.

The planting device 4 includes a seedling platform 5 that can be moved back and forth in the lateral direction, a planting mechanism 6 that operates in conjunction with the lateral movement of the seedling platform 5, and a soil leveling float 7, which are arranged behind the link mechanism 3. A pair of links 8 at the end,
The structure is such that it is attached to a planting frame 9 which is suspended and supported via a frame 8 so as to be freely rolling.

As shown in FIGS. 1 and 2, the planting mechanism 6 has a planting arm 10 attached to the planting frame 9 so as to circulate up and down via a drive crank arm 11 and a swing link 12. The planting arm 10 has a planting claw 14 that takes out a unit amount of seedlings from the seedling take-out port 13 and plants them on the soil leveling mud surface as the planting arm 10 circulates, and the planting claw 14 plunges into the soil leveling mud surface. A seedling pusher 15 that detaches the taken-out seedlings held by the planting nails 14 from the planting nails 14 by sliding along the longitudinal direction of the planting nails 14 at a timely manner.
and a soil gathering tool 16 that swings in conjunction with the circulation operation of the planting arm 10 to press and move mud from both left and right sides toward the planted seedlings.

The driving means for the seedling pushing tool 15 includes a swinging arm 17 that slides the seedling pushing tool 15 in the planting arm 10, and a spring 18 that swings and urges the swinging arm 17 toward the seedling pushing side. At the same time, the swinging arm 1 is attached to the drive crankshaft 11 by the urging force of the spring 18 at the timing when the planting claw 14 enters the soil leveling mud surface.
This is means for fixing the cam 19 that allows the cam 7 to swing toward the seedling extrusion side.

The means for driving the mulch tool 16 includes a slide member 20 that is pressed and swung by the swing arm 17 that swings toward the extrusion side to push the mulch tool 16 from a standby position to press the mud; This is a means of providing a spring 21 for swinging the soil gathering tool 16 back to the standby position.

22, 22, as shown in FIG. 4, pull upward near both left and right ends of the planting frame 9 to suppress rolling of the planting device 4 relative to the link mechanism 3 due to lateral movement of the seedling stand 5. 23 is a balance spring fixed to one end of the balance springs 22, 22, and by swinging from side to side, the balance springs 22, 2
The operating lever 23 is an operating lever for adjusting the pulling force of the operating lever 23, and the swinging guide 24 of the operating lever 23 is formed with an engaging portion 25 that engages and fixes the operating lever 23 at each of a plurality of operating positions. There is.
Therefore, as shown in FIG. 4, when the tiller a and the mud surface b are both tilted left and right, and the riding machine 2 is working on the ridge in a tilted posture, the balance spring 22 on the ridge side is By adjusting the tensile force of the planting device 4 to be weaker and making the grounding load of the planting device 4 on the mud surface on the ridge side larger than that on the other side, Regardless of the slope,
This allows the planting device 4 to be held in a horizontal position.
