In-line planting device of transplanter

Abstract

The invention provides an in-line planting device of a transplanter. The in-line planting device is used for perforating cavitation and plant setting operations of transplanting on a film, belongs to the field of agricultural machinery and consists of a driving device, a planting apparatus, a control mechanism and a stand. The reciprocating linear motion of the planting device can be realized by driving a crank link mechanism to act through power. The planting apparatus is in a closed state when moving to a top dead point; pot seedlings are fed into the planting apparatus by a seedling feeding device; the planting device penetrates a mulching film, enters soil and punches holes along the process that the planting apparatus moves to a lower dead point and the planting apparatus is opened under the action of the control mechanism; the pot seedlings are fed into the cavities to finish the seedling planting operation; and then the planting apparatus is closed by a rising control mechanism of the planting apparatus, and thereby next working cycle is turned into. The short planting distance thick planting transplantation can be realized by adjusting the rotating speed of a crank and improving the reciprocating frequency of the planning apparatus. Since the motion curve of the planting apparatus is consistent with that of the pot seedlings in the seedling feeding process, the frequency and the reliability of feeding seedlings can be improved.

Description

Technical field [0001] The in-line planting device of the transplanter provided by the present invention is used for punching, hole forming and seedling planting operations of transplanting on a film, and belongs to the field of agricultural machinery. Background technique [0002] At present, the hanging cup type planter is commonly used in pot seedling transplanting machinery on the membrane. Generally, 6 hanging cups are installed on the disc and rotated by the ground wheel. When the hanging cup rotates to the upper front, the seedling throwing device puts the pot seedlings into the hanging cup, and when it continues to rotate to the ground, it enters the soil and punches, and the duckbill of the hanging cup is opened by the cam mechanism to cast the seedlings. Because the bowl seedlings do a vertical falling motion during the seedling throwing process, and the hanging cup makes a circular motion, the movement time and position are required to be very accurate, the control mec...

AI Technical Summary

Problems solved by technology

Because the seedlings in the seedlings are dropped vertically while the cups are in a circular motion, the movement time and position are required to be very precise, the control mechanism is relatively complicated, and the rotation speed of the hanging cups is relatively low, otherwise seedling leakage will occur. , and the productivity is also low, generally 40 plants / minute

In addition, limited by the structure and movement of the hanging cup, the distance between plants for transplanting should generally not be less than 200 mm, so it is difficult to meet the needs of large-scale dense planting.
