Lifting type rice seedling-raising tray and lifting adjustment method

Abstract

The invention discloses a lifting type rice seedling-raising tray and a lifting adjustment method, belonging to the technical field of rice cultivation. The lifting type rice seedling-raising tray comprises a base plate, wherein four corners of the bottom part of the base plate are respectively provided with a supporting inner drum; the bottom part of each supporting inner drum is in sleeve connection with a supporting sleeve drum; a fastener is connected with and arranged between each supporting inner drum and each supporting sleeve drum; the outer wall of each supporting sleeve drum is uniformly provided with bolt holes; a reinforcer is arranged between every two supporting sleeve drums; a driving screw rod is horizontally inserted into the interior of the base plate; one end of the driving screw rod penetrates through the outer walls of the base plate; the outer wall of one end of the driving screw rod is in sleeve connection with a rotary knob; one side of the driving screw rod ismeshed with two driven screw rods; and a lifting plate is arranged at the top parts of two driven screw rods. The lifting type rice seedling-raising tray provided by the invention has the following advantages: the bearing capacity of a rice seedling-raising tray is improved; the rice seedling-raising tray is safer to use; the supporting height of the whole structure is adjustable; connection is extremely firm and convenient; and assembling is convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a lifting rice seedling raising tray and a lifting adjustment method. Background technique [0002] Rice is native to tropical Asia and is an annual grass plant with 24 chromosomes. After being widely planted in China, it gradually spread to all parts of the world. The rice seedling tray is a new type of seedling raising method that is matched with throwing seedlings. The quality of the seedlings directly affects the quality of the throwing seedlings and the level of rice yield. [0003] Seedling cultivation in seedling trays requires good environmental factors such as light, humidity, and nutrition for seedlings. As the seedlings grow, their growth angle will change, and manual adjustment is required. The height of the existing rice seedling trays is fixed. Invariably, the height cannot be adjusted in the process of raising seedlings and in the process of inserting se...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of lifting type rice seedling raising tray and the method of lifting adjustment, to solve the above-mentioned background technology with the growth of raising seedlings, its growth angle will change, then need to manually adjust it, the existing The height of the rice seedling tray is fixed, and the height cannot be adjusted during the seedling raising process and the seedling insertion process. It is inconvenient to use, the use effect is not good, and it is not convenient to deal with it after it is raised and lowered.
