An alfalfa transplanting machine and method for adjusting the transplanting posture of alfalfa pot seedlings

Abstract

The invention belongs to the field of agricultural machinery, and relates to an alfalfa transplanting machine for adjusting the transplanting posture of alfalfa pot seedlings and a method. The alfalfatransplanting machine comprises a rack, a pot seedling posture adjusting and seedling taking mechanism, a seedling feeding mechanism and a seedling tray conveying mechanism, the pot seedling postureadjusting and seedling taking mechanism comprises a posture adjusting and seedling taking unit and a seedling sending unit, and the seedling sending unit comprises a guide rail side baffle, a rack, aconveying gear, a guide rod, a conveying motor and a conveying sliding block. The posture adjusting and seedling taking unit comprises a clamping paw, a clamping plate, an adjusting stand column, an adjusting plate, a driven gear, a clamping adjusting motor, a driving gear and a clamping adjusting mounting base. The clamping plate and the adjusting plate are located on the same horizontal plane and vertically intersect in the middle so as to form a cross-shaped structure. The alfalfa transplanting machine has the advantages that the automation degree is high, the posture of the alfalfa pot seedlings can be adjusted, and the alfalfa pot seedlings can be automatically clamped and conveyed, the alfalfa transplanting machine can be adjusted according to the transplanting requirement of row spacing and plant spacing, and the alfalfa transplanting machine is high in applicability and suitable for being popularized and used in a wide range.

Description

technical field [0001] The invention relates to an alfalfa transplanting machine and a method for adjusting the transplanting attitude of alfalfa seedlings in a pot, which belong to the field of agricultural machinery, and are especially suitable for the environment where a large amount of alfalfa pots are artificially raised and the transplanting efficiency is relatively high. Background technique [0002] Alfalfa is a perennial high-quality forage grass, known as the "king of forage grass" because of its rich nutrients and wide application. The development of alfalfa industry is of great significance to adjust the planting structure, promote the process of "grain to feed" and enhance the market competitiveness of grass products and livestock products. In recent years, the country has implemented the action of revitalizing the development of dairy industry alfalfa, and the production of high-quality alfalfa has been effectively developed. According to industry statistics, ...

Problems solved by technology

[0006] A multi-functional self-propelled combined vegetable transplanting machine (application number: 201510431798.X), the device includes a body and its connected engine and drive shaft, capable of transplanting vegetables and vegetables of different specifications Selective transplanting, but the device is more complicated and the applicability is poor

[0007] The pot seedling transplanter starts the seedling picking device (application number: 201610160034.6). The device uses a four-bar mechanism and pneumatic drive to take seedlings. The movement process of the device is relatively fixed. For irregular seedling trays during the placement of seedling trays, Due to the relatively fixed trajectory of the device, the process of picking seedlings is likely to cause damage to seedlings and leakage of temples.

[0008] An end effector for pot seedling transplanting machine with controllable picking and throwing of seedlings in trays (application number: 201510542278.6). The situation of injured seedlings and exposed seedlings in the process of taking seedlings is still not considered. At the same time, the seedlings of the above two devices are taken through a single seedling process, and the efficiency of the device is generally low.
