Problems solved by technology

[0005] In the seedling transplanting device of the above-mentioned structure, there is such a problem: when making the planting interval in the front and rear direction of the seedlings, that is, the distance between plants becomes larger (especially 37 to 42 plants), or increasing the walking speed to make the planting drive shaft When the rotation becomes faster, the rotation speed of the rotating housing increases or decreases, and the vibration caused by the meshing with the gears resonates
Due to this resonance, the vibration amplitude of the seedling planting device part becomes large, and there is a problem that the seedling planting device cannot take out the seedlings and the seedlings are missing, or the seedlings cannot be planted at the proper planting position.
[0007] However, depending on the combination of eccentric gears, the trajectory of the front end of the planting will change, the planting depth of the seedlings will become shallower, and the seedlings that should be planted will disappear due to wind or water flow, and there will also be problems such as missing plants.

Embodiment Construction

[0083] Hereinafter, embodiments specifically configured based on the above-mentioned technical idea will be described with reference to the drawings. And, with the forward direction of the rice seedling transplanting machine as a reference, front and rear and left and right are respectively set. exist figure 1 and figure 2 In , the right side view and top view of the riding-type rice transplanter equipped with the rice seedling planting device of the present invention are shown.

[0084] In this passenger type rice transplanter, the traveling vehicle body 10 is equipped with an engine 11, and has a pair of left and right front wheels 12 and rear wheels 13 that are driven to rotate. The rice seedling planting part 15 of 6 row planting type is connected.

[0085] In addition, a driver's seat 16 , a joystick 17 for manipulating the front wheels 12 , and a preliminary seedling mounting table 18 on which a preliminary seedling is placed are provided on the traveling vehicle bod...

Abstract

The invention provides a seedling transplanting device, wherein the spacing among seedlings is made larger, so that the travellign speed is improved. Meanwhile, the rotating speed of a transplanting rotation shaft is improved, and the vibration / resonant oscillation of a transmission rotator is prevented. The transplanting rotation shaft (30) is provided with a rotation housing (31) and the rotation housing is provided with a transplanting rod (27). The rotation housing is provided with an eccentric input gear (40) capable of freely rotating relative to the transplanting rotation shaft (30); a rotating shaft (34) for driving a cultivation rod to rotate is provided with an eccentric output gear (42); and a relay input gear (41) used for transmitting the drive power from the eccentric input gear to the eccentric output gear.

Description

technical field [0001] The present invention relates to a seedling transplanting device installed in a seedling transplanting machine such as a rice transplanter. Background technique [0002] Mechanisms disclosed in Patent Document 1 and Patent Document 2 are known as a seedling planting device for taking out seedlings from a seedling blanket mounted on a seedling mounting table at the rear of a seedling transplanting machine and planting them in a field. The seedling planting device includes a left and right rotary housing that rotates around a planting drive shaft in the left and right directions, and a seedling transplanter having seedling claws and a seedling ejector is disposed at both ends of the rotary housing. During the rotation of the rotary housing, the front end of the seedling transplanter protrudes toward the outer circumference of the rotary housing to draw a roughly elliptical planting trajectory to separate and plant the seedlings.
