Seedling taking device for automatic transplanting machine

Abstract

The invention discloses a potted tray seedling taking device for an automatic transplanting machine. The device mainly comprises a crankshaft sliding chute door-shaped combined mechanism, seedling taking claws, a cam swinging rod mechanism and a drawing wire, wherein the crankshaft sliding chute door-shaped combined mechanism is formed by connecting a crankshaft door-shaped guide rod mechanism and a cam sliding chute mechanism in series; the cam swinging rod mechanism is used for controlling the opening and the closing of the seedling taking claws; the seedling taking claws are fixed on a door-shaped beam and is driven by the crankshaft door-shaped guide rod mechanism to form a seedling taking trace; the crankshaft guide rod mechanism is used by the mechanism to ensure that the seedling taking claws are used for taking seedlings and pushing the seedlings at a low speed and the seedling taking claws return along with the seedlings or without any seedling at a high speed; the seedling taking claws can be inserted into a potted tray in a vertical linear track and can be used for delivering the seedlings above a vertical transplanting device; and as the door-shaped mechanism is used, a plurality of seedling taking claws can be arranged at the same time. The mechanism is controlled only by a machine, and a large quantity of external auxiliary power devices are not required to additionally arrange, so that the device has a simple structure, is low in cost, high in success rate of seedling taking and seedling delivering and high in overall efficiency, and can be applied to the field of automatic transplantation of the potted tray seedlings.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic seedling picking device applied to an automatic transplanting machine for seedlings in plug trays. Background technique [0002] Transplanting can avoid natural disasters in the early stage of seedlings, and can make full use of light and heat resources. It has a comprehensive effect on climate compensation, early maturity of crops and increased income, and has huge economic and social benefits. For a long time, transplanting has always been a It is a labor-intensive operation, which accounts for about 20% of the total labor required for crops from sowing to harvesting. [0003] At present, there are semi-automatic and fully automatic transplanting machines on the market. The semi-automatic transplanting machine uses the planter to plant seedlings, but it needs to manually take the seedlings from the hole tray and throw the seedlings. This kind of transplanting ...

Problems solved by technology

Among the relevant published patents, such as the patent CN201491493U discloses an automatic seedling picking device, which adopts a combination of machinery and electricity. Although automatic seedling picking is realized, a power supply, an air compressor, and a pneumatic cylinder Such as electric control system, many auxiliary devices, large matching power, high cost of use; patent CN101940102A discloses a seedling picking mechanism of a plug seedling transplanting machine, which can realize the action of clamping seedlings and throwing seedlings of seedling claws, but the The seedling picking track of the mechanism is a closed duckbill shape, that is, the trajectory of inserting the seedling claws into the substrate and pulling out the substrate after clamping the seedlings is not the same straight line. When picking seedlings, it is easy to crush the seedlings in the pot. Low success rate, easy to damage seedlings
