Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a seedling planting operation assembly on a rice seedling pot planting machine. Background Art

[0002] The swing planting of rice seedlings in pots is an advanced new agronomic technology method that has been successfully researched and started to be promoted and applied in recent years. The seedling planter is an instrument to complete and realize the mechanized operation of swing planting of rice seedlings in paddy fields. When the existing seedling planter is swing planting the rice seedlings in the paddy field, it only needs to clamp the front end of the rice seedlings in the paddy field with the seedling planting claws of the seedling planter and implant it into the paddy field soil, and rely on the soil resistance to comb the rice seedlings off the seedling planting claws to complete the seedling planting operation. In the operation practice, it is found that the above-mentioned existing seedling planter has many technical problems that need to be solved, such as poor quality of rice seedlings in pots, unstable seedlings, slow planting speed, low operation efficiency, high requirements for paddy field land conditions, and poor ability to adapt to soil. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of the mechanized operation of rice seedlings in pots, and study and design a paddy field seedling planting and pushing seedling transplanter, so as to achieve the purpose of good quality of rice seedling planting, high operation efficiency and strong ability to adapt to land conditions.

[0004] The basic design of the present invention is as follows: a connecting seat plate and a seedling planting claw plate are fixedly mounted on the bottom of the claw seat frame from left to right in sequence, a seedling fork is opened on the right end of the seedling planting claw plate, a driving block is fixedly mounted on the connecting seat plate, the left and right ends of the connecting rod are respectively fixedly connected to the driving block and the claw seat frame, a positioning configuration and a self-rotatable seedling pushing active shaft are fixedly mounted on the driving block, a seedling pushing lever is hingedly mounted on the upper end of the claw seat frame through an upper pin shaft so as to be able to swing left and right, a return torsion spring sleeve is mounted on the upper pin shaft, and the return The two ends of the positioning torsion spring are respectively contacted and positioned with the seedling pushing lever and the claw seat frame, and a seedling pushing plate is slidably arranged in the fork of the seedling pot. The lower part of the seedling pushing lever is hingedly connected to the left end of the seedling pushing rod through a lower pin shaft, and the right end of the seedling pushing rod is connected to the seedling pushing plate. A push rod seat is fixedly arranged and installed on the right side of the claw seat frame and above the seedling planting claw plate. The push rod seat is in contact or non-contact cooperation with the upper end of the seedling pushing lever, thereby constituting a paddy field seedling swinging and seedling pushing type seedling planter.

[0005] The invention adopts a compulsory seedling pushing structure. While pushing the rice seedlings off the seedling planting claw plate, the rice seedlings are continuously pushed into the paddy field soil with force to complete the mechanized seedling planting operation. The invention has the characteristics of novel, unique and reasonable structure, good seedling planting operation quality, high efficiency, strong ability to adapt to land conditions, reliable use and low seedling injury rate, and provides technical support for the promotion of advanced new agronomic technology for paddy field seedling planting.

DETAILED DESCRIPTION

[0013] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A paddy field seedling swinging and pushing seedling planting device, a connecting seat plate 14 and a seedling planting claw plate 10 are fixedly installed on the bottom of a claw seat frame 7 from left to right in sequence, a seedling fork 9 is provided on the right end of the seedling planting claw plate 10, a driving block 12 is fixedly installed on the connecting seat plate 14, the left and right ends of the connecting rod 6 are respectively fixedly connected to the driving block 12 and the claw seat frame 7, a positioning configuration and self-rotatable seedling pushing active shaft 8 is fixedly installed on the driving block 12, a seedling pushing lever 1 is hingedly installed on the upper end of the claw seat frame 7 through an upper pin shaft 4 so as to swing left and right, and a return torsion spring 3 is provided. The seedling pushing plate 11 is slidably mounted in the seedling fork 9, and the left end of the seedling pushing rod 13 is hingedly connected to the seedling pushing plate 11 through the lower pin 2 on the lower part of the seedling pushing lever 1. The right end of the seedling pushing rod 13 is connected to the seedling pushing plate 11. A push rod seat 5 is fixedly installed on the right side of the claw seat 7 and above the seedling planting claw plate 10. The push rod seat 5 is in contact or non-contact with the upper end of the seedling pushing lever 1.

[0014] During operation, the external power drives the positioning configuration of the seedling pushing active shaft 8 to rotate clockwise, and the claw seat frame 7 is driven to rotate clockwise as a whole through the driving block 12, the connecting rod 6, and the connecting seat plate 14 in turn. Synchronously, the lower pin 2, the seedling pushing rod 13 and the seedling pushing plate 11 are driven by the upper pin 4 to rotate clockwise together through the seedling pushing lever 1. When the upper end of the seedling pushing lever 1 rotates to contact the fixed push rod seat 5, the push rod seat 5 is resisted, so that the seedling pushing lever 1 rotates counterclockwise around the upper pin 4 on the claw seat 7. The lower pin 2 and the seedling pushing rod 13 are used to drive the seedling pushing plate 11 to move to the right end in the seedling fork 9 on the seedling planting claw plate 10, and the rice seedlings located in the seedling fork 9 are pushed out and squeezed into the paddy field soil, completing the rice seedling swing planting operation. Then the seedling pushing active shaft 8 rotates counterclockwise as a whole, and the seedling pushing lever 1 is separated from the contact and cooperation with the push rod seat 5. Under the torsion of the return torsion spring 3, the seedling pushing lever 1 rotates clockwise around the upper pin shaft 4 on the claw seat frame 7 as a whole, and the lower pin shaft 2 and the seedling pushing rod 13 drive the seedling pushing plate 11 to move to the left end in the seedling pot fork 9 on the seedling planting claw plate 10, and the seedling pushing plate 11 returns to the initial position. The cycle is repeated in sequence, and the operation is continuous. After planting, the rice seedlings are planted firmly, the floating seedling phenomenon is not easy to occur, and the seedlings have good uprightness.
