Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention comprises a seedling platform that reciprocates from side to side, and a planting claw that takes out one seedling from the seedling platform and plants it continuously. The present invention relates to a planting device for a rice transplanter that performs rice transplanting work.

``Prior Art'' Conventionally, there has been a technique for adjusting the length of the seedling mat by adjusting the length of the planting claw or the height of the seedling take-out plate.

``Problems that Paper Cans Try to Solve'' In all of the above-mentioned conventional techniques, the amount of seedlings removed is set before the start of the rice transplanting operation, and during the rice transplanting operation, the seedling mat is set at a constant amount of seedlings set in advance. be cut off.

However, after moving the seedling mat horizontally and cutting one line,
This is because when the seedling mantle is vertically fed one step to the sloping lower end side of the seedling platform, it is not completely fed instantaneously.

The amount of seedlings removed from the end of the seedling pine that is cut immediately after vertical feeding is smaller than the amount of seedlings removed from the center of the seedling pine that is cut during horizontal movement. For this reason, the seedling mat is cut into a circular arc shape, and the insufficient amount of seedlings removed remains in a triangular shape at the end of the seedling mat, and a gap is created between the center of the 1m mat and the seedling removal plate, causing the bacterial mat to collapse. There was a problem that caused this.

However, the present invention is provided with a seedling vertical feed amount adjustment member of a planting claw that is linked with the left and right reciprocating movement of the seedling platform for horizontally moving the seedling mat, The structure is such that the amount of vertical seedling removal by the planting claw at the end can be increased compared to the amount during the reciprocation.

"Function" Therefore, according to the present invention, by increasing the amount of vertical seedling removal of the planting claw at the left and right reciprocating ends of the seedling platform using the seedling removal amount adjusting member than during the reciprocation, It solves the problem of insufficient amount of seedlings taken vertically, eliminates the triangular uncut edges at the ends of the seedling pine and the gap between the center of the seedling pine and the seedling removal plate, which prevents the seedling mat from collapsing. This makes it possible to carry out rice transplanting work more smoothly than before, and to obtain a stable harvest amount.

This embodiment is constructed as described above, and has a planting claw drive shaft (3
By continuously rotating the rotary case (21) and the bearing case (83) in one direction at a constant speed around this in the longitudinal direction of the aircraft, each gear (4B) (48) (4
9), the claw case shaft (5) rotates at an inconstant speed, and the planting claw (17) is placed in the seedling cutting position in front of the seedling removal port (37).
In addition, the planting claws (17) are moved to the planting position while entering the rice field, and one strain of bacteria is planted by turning the rotary case (21) half a turn.

In addition, the seedling platform (16) is reciprocated left and right by the horizontal feed drive shaft (56), and at the left and right reciprocating ends of the seedling platform (16), the vertical feed cam (66) of the vertical feed drive shaft (57) is moved. The vertical feed roller (65) is rotated clockwise together with the vertical feed shaft (87), and the seedling mat (89) is
) to the slanted lower end side of the seedling stand (1B).

When one of the swing levers (71) is pressed by one of the bushing arms (70) immediately before this vertical feeding operation, that is, near the end of the left and right reciprocating movement of the seedling platform (16), the wire (7
8) (79) is pulled and the inch holder is attached to the bracket (
80) (80) to the left and right fulcrum shafts (77) (??)
Rotate counterclockwise. Therefore, the left and right reverse-shaped links (75) (75) rotate upward around the fulcrum shafts (77) (77), and resist the force of the springs (85) (85) to act as a seedling vertical harvesting amount adjusting member. Phase adjustment lever (47) (
47) is rotated upward around the drive shaft (38) (38). When the lever (47) (4?) rotates upward, the sun gear (20b) moves against the chain case (20b) (20b).
38) The position fixing angle of (3B) changes, and the planting trajectory (X) of the planting claw (17) rises as shown by the imaginary line in Fig. 5, and the planting claw (17) moves the seedling mat (69). ) is increased at the left and right reciprocating ends of the seedling platform (1B), that is, at the end of the sprouting mat (89), than in the middle of the left and right reciprocating of the seedling platform (16), that is, at the center of the seedling mat (f19). I can do it.

Further, when the above-mentioned vertical cutting amount is temporarily converted, a sharp increase occurs.

Therefore, even if the seedling mat (89) is not completely vertically fed instantaneously, the seedling mat (69) immediately after the seedling is vertically fed.
By cutting off more at the ends than at the center, it is possible to prevent insufficient amount of seedlings from being removed vertically at the end of the seedling mat (89) due to a delay in the vertical feeding of the seedlings, and to obtain a constant amount of seedlings from the vertical direction at all times.

Note that the seedling vertical removal amount adjusting member (47) is attached to the seedling stand (16).
) can be operated near the end of the left and right reciprocating movement of the horizontal feed drive shaft (56), so instead of using the bushing arm (70) provided on the horizontal feed drive shaft (56), the amount of vertical seedling removal can be directly adjusted using the convex portion on the lower surface of the seedling stand (16). It is also possible to actuate the member (47), and the actuating operation of said adjusting member (47) is not limited to this.

Note that the support height of the seedling take-out plate (36) may be changed instead of the phase adjustment lever (47) (47).
