Problems solved by technology

The structure and operation steps such as chain intermittent movement, top pre-separation and lateral movement are relatively complicated, and the operation efficiency is relatively slow, and the two-finger ejector rod is easy to cause damage to the pot body and stems and leaves during the extrusion and reset process
[0009] This kind of seedling-picking mechanism based on the upward seedling-picking method has a complex structure, many operating links, and some damage to the seedlings and pots, so it is difficult to further increase the operating frequency.
Therefore, it has not been possible to develop a high-speed and low-loss seedling-taking and throwing mechanism based on the upward seedling picking method and to promote and apply it on a large scale.

Abstract

The invention belongs to the technical field of agricultural mechanical transplanting, and particularly relates to an automatic tray supply high-speed seedling taking and throwing device of an automatic tray seedling transplanter. The device comprises a rack, a tray supply device, a seedling feeding device, a seedling taking device, a seedling throwing device, a tray collection frame and a control system, wherein the tray supply device comprises a tray supply chain driving motor, a tray supply chain wheel shaft, a tray waiting position sensor, a plurality of trays, a tray positioning guide bearing, a tray supply chain, a tray suspension wire and the like; the seedling feeding mechanism comprises a seedling feeding chain, a plurality of lengthened pin shafts, a seedling feeding chain wheel, a seedling feeding bottom plate and the like; the seedling taking device comprises a seedling taking ejector rod, an air cylinder mounting plate, a seedling taking air cylinder and the like; the seedling throwing device comprises a seedling throwing hopper and a seedling throwing sensor; and the control system comprises a power supply, a control button, a microcontroller and the like. According to the invention, automatic tray supply is achieved, tray seedlings are continuously and downwards taken out at a high speed, the seedlings are directly thrown through the seedling throwing hopper, the seedling taking and throwing movement directions and spatial positions are consistent, and the operation efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanized transplanting, and in particular relates to a device for picking and throwing seedlings at a high speed with an automatic tray seedling automatic transplanter. Background technique [0002] Seedling transplanting is an important agronomic technology in the production process of crops. It can increase the accumulated temperature, avoid adverse climate effects in the seedling stage, mature early, achieve high yield and high quality, and increase its multiple cropping index. Transplanting can also establish the early growth advantage of crops over weeds, which is beneficial to inhibit the growth of weeds and improve the use efficiency of water and fertilizer in the field. [0003] Transplanting is a labor-intensive link, and the comprehensive mechanization rate is very low, only about 20%. Labor costs have already accounted for 40% to 60% of the total cost of crop production. The rise...
