Paper strip type pot seedling transplanting operation automatic seedling supply and cutting mechanism

Abstract

Belonging to agricultural machinery, the invention provides a paper strip type pot seedling transplanting operation automatic seedling supply and cutting mechanism. Specifically, a cutterhead shaft, a camshaft and a screw rod are mounted on a frame in parallel, a sawtooth cutterhead and a driven wheel are fixedly mounted on the cutterhead shaft, two cams are fixedly disposed on the camshaft symmetrical to each other, a drive wheel is fixed on the camshaft, and two push rods respectively sleeved with a pressure spring are mounted on the frame and can move up and down. A paper strip type pot seedling track is fixedly mounted on the upper ends of the push rods, the lower ends are in close contact cooperation with the cams, a driving belt is sleeved on the driving wheel and the driven wheel, a nut is assembled on the screw rod, the screw rod is in fixed connection with the nut, a stepping motor and the motor are respectively connected to the screw rod and the camshaft. The mechanism provided by the invention has the advantages of novel, reasonable and simple structure, high operation efficiency and automation degree, low operation labor intensity, and reliable use, and especially can meet and adapt to large area transplantation operation of paper strip type pot seedlings.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an automatic seedling-supplying and cutting mechanism that satisfies and adapts to the operation of transplanting seedlings in a paper strip type pot. Background technique [0002] In order to increase the yield per unit area of ​​dry field crops such as corn, an agronomic method of transplanting pot seedlings in dry fields has begun to be popularized and applied. The traditional method is as follows: firstly, the upland crops are raised in a plastic tray to raise seedlings in pots. During the transplanting operation, the potted seedlings must be taken out of the plastic tray first, and then the potted seedlings must be manually sent to the planting machine one by one to complete the field transplanting operation, which is labor-intensive and low-efficiency. In particular, it is a problem that must be solved that it cannot meet the needs of large-scale transplanting operations. In...

AI Technical Summary

Problems solved by technology

During the transplanting operation, the potted seedlings must be taken out of the plastic tray first, and then the potted seedlings are manually sent to the planting machine one by one to complete the field transplanting operation, which is labor-intensive and low-efficiency. In particular, the inability to meet the needs of large-scale transplanting operations is a problem that must be solved

In recent years, pot seedling transplanting machines with ejector or manipulator structures have been developed to adapt to the transplanting of pot seedlings in plastic pot seedlings. In addition to the technical problems of complex structure, difficult control, and many operational failures, other The efficiency of transplanting operation still cannot meet the requirements of large-scale transplanting operations
