[0018] Example 2: A flexible disc planter, the drive shaft 7 is rotatably installed on the frame 9 through the bearing seat 6, the rigid disc 2 and the flexible disc 8 are fixed on the drive shaft 7, and the On the flexible disk 8, the swing rod 14 is hingedly installed through the hinge pin 11. The swing rod 14 is uniformly distributed along the circumferential direction and arranged radially on the flexible disk 8. On the edge of the outer end of the swing rod 14, a ring-shaped elastic connection is fixed. The plate 3 and the heavy foam 1 are respectively fitted on the outer edge of the rigid disc 2 and the swing rod 14, and the pressure adjusting bolt 12 with the compression spring 13 is fitted on the rigid disc 2 in an axially movable manner. One side end surface of spring 13 is press-contacted with swing rod 14, and opening adjustment support 5 is fixedly mounted on frame 9, and bowl disc gap adjustment assembly 4 is assembled on opening adjustment support 5, and is connec...

example 3

[0019] Example 3: The bowl plate gap adjustment assembly 4 is composed of the pot seedling feeding opening adjustment system 4.2 and the pot seedling release position adjustment system 4.4, and the pot seedling feeding opening adjustment system 4.2 is fixed by the axial position adjustment screw 4.3. Installed on the opening adjustment support 5, the pot seedling release position adjustment system 4.4 is fixedly fitted on the pot seedling feeding opening adjustment system 4.2 through the circumferential adjustment bolt 4.5, and the pot seedling feeding opening adjustment system 4.2 and pot seedling Bearings 4.1 are assembled respectively on the ends of the release position adjustment system 4.4.

[0020] During operation, the flexible disk 8 and the rigid disk 2 rotate coaxially and synchronously with the drive shaft 7, and the annular elastic connecting plate 3 is separated from the edge of the rigid disk 2 under the action of the leaf spring 10 or compression spring 13 and th...

Abstract

The invention relates to a flexible circular disc type planting device, which belongs to agricultural machinery. A driving shaft is arranged on a machine frame through a bearing seat, a rigid circular disc and a flexible circular disc are fixedly arranged on the driving shaft, plate springs are fixedly arranged in the radial direction on the flexible circular disc and are uniformly distributed in the circumferential direction, an annular elastic connecting plate is fixedly arranged on the outer end edge position of the plate springs, heavy body foam is respectively assembled on the outer end edge positions of the rigid circular disc and the plate springs, an opening degree regulating support seat is fixedly arranged on the machine frame, a pot disc gap regulating assembly is assembled on the opening degree regulating support seat and is in contact matching with the annular elastic connecting plate, or a swinging rod is arranged on the flexible circular disc through a hinging pin, an annular elastic connecting plate is fixedly arranged on the outer end edge position of the swinging rod, the heavy body foam is respectively assembled on the outer end edge positions of the rigid circular disc and the swinging rod, a pressure regulating screw bolt with a press spring is assembled on the rigid circular disc, and the press spring is in contact matching with the swinging rod. The flexible circular disc type planting device has the advantages that the structure is novel and reasonable, the use is reliable, the pot seedling transplanting operation quality is good, the efficiency is high, the faults are fewer, and the application range is wide.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a planting operation part on a pot seedling planting machine in dry land. Background technique [0002] At present, the flexible disc planter is composed of a pair of axes forming a certain inclination angle and synchronously rotating counterclockwise at a certain angular velocity. The edges of the two discs are in a state of close contact at the third quadrant angle. , The edge of the disk at the corner of the second quadrant is in a separated state. Feed pot seedlings at the corner of the fourth quadrant, clamp and transport the pot seedlings to the formed pits or grooves on the ridge surface at the corner of the third quadrant, and put the pot seedlings into the second quadrant area Holes or trenches to complete the transplanting process. Due to the influence of the rigid disk and the mechanical structure, the phenomenon of seedling leakage and pinching of the pot seedlings is ...
