Novel rice seedling hole tray breeding device

Abstract

The invention discloses a novel rice seedling hole tray breeding device which comprises an arc-shaped plate, wherein a first connecting rod is fixed with a side surface of the arc-shaped plate; two second connecting rods are moveably mounted at the lower end of the side surface of the arc-shaped plate through first through holes; support plates are fixed on side surfaces of the second connecting rods; chutes are formed in side surfaces of the support plates; and third connecting rods are fixed on side surfaces of lower ends of the support plate. Due to arrangement of the arc-shaped plate, thefirst connecting rods, the first through holes, the second connecting rods, the support plates, third connecting rods, L-shaped buckles, first hole trays, magnetic blocks, first clamping rods, secondclamping rods, third clamping rods, fourth connecting rods, second hole trays and anti-sliding strips, the whole device can be folded and closed up, then the device can be convenient to move and store, and the utilization rate of space can be increased; and due to arrangement of the chutes, threaded rods, limiting rods and hand-screwed caps, vertical distances of adjacent first hole trays can be conveniently and rapidly adjusted, and thus the working efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of seedling raising devices, in particular to a novel rice plug seedling raising device. Background technique [0002] Plug seedling raising is a new seedling raising technology that emerged in the 1970s in European and American countries. It was listed as a key scientific and technological project of the Ministry of Agriculture during the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" in my country. It has become the main way of specialized commercial seedling production in many countries. Plug seedling technology is a modern seedling technology that uses peat, vermiculite and other light-substrate soilless materials as the seedling substrate, and seedlings are seeded manually or mechanized at one time. It is widely used in greenhouse seedling cultivation. Along with the development of plug seedling raising technology, the seedling raising device related to it has also obtained further development an...

Problems solved by technology

[0004] The purpose of the present invention is to provide a novel rice seedling raising device to solve the problem that most of the existing rice seedling raising devices are layered and fixed frame structures, which cannot be folded and folded after use, are inconvenient to carry, and take up space when stored; The vertical spacing of the separation layers on the frame is adjusted and fixed in the early stage. When adjusting the vertical spacing between the separation layers again, the bolts need to be removed, which is troublesome and inefficient to operate. The device lacks necessary lighting facilities, resulting in insufficient light for plants in rainy days and slow growth The problem
