Equipment for filling tray with substrate for tobacco floating seedling raising

Abstract

The invention relates to equipment for filling a tray with a substrate for tobacco floating seedling raising. The equipment comprises a substrate box, a pressing connection device, a charging shovel and a blocking device, wherein the substrate box comprises an upper box body and a lower box body which are both provided with a top opening and a bottom opening and vertically assembled; the blockingdevice comprises gauze used for blocking the bottom opening of the lower box body, the two ends of the gauze are wound around a driving roller and a driven roller respectively, a tensioning roller isparallel to the driving roller and is used for tensioning the gauze and making the gauze fit the bottom face of the lower box body, the charging shovel comprises a frame body provided with a top opening and a bottom opening, and the top and bottom of the inner side wall of the frame body in the length direction slidably cooperate with an upper material plate and a lower material plate; the pressing connection device comprises a base plate and multiple square frames fixedly arranged on the bottom of the base plate, the tops of the square frames are provided with stirring rods, and the stirringrods are connected with an external stirring driving mechanism. The equipment has the advantages that the structure is simple, blending of turf, vermiculite and perlite can be effectively achieved, and seedling holes of the seedling raising tray are filled with the substrate uniformly as soon as possible, so that matching of the substrate components in each seedling hole is reasonable, and the survival rate and activity of the tobacco seedling are improved.

Description

technical field [0001] The invention belongs to the field of tobacco planting, and in particular relates to a substrate packing device for floating seedling raising of tobacco. Background technique [0002] At present, the tobacco seedlings in my country basically adopt the floating seedling cultivation method of greenhouse management: after compounding the substrate and stirring it evenly, the substrate is put into the seedling tray, and then the coated tobacco seeds are sown into the seedling hole of the seedling tray, and then the seedling tray It can be cultivated in the seedling pond. The existing seedling trays have been produced in standard specifications and are mostly made of foamed plastics. Holes are provided on the bottom wall of the seedling hole so that the nutrient solution in the seedling pool can enter the inner matrix of the seedling hole and supply the tobacco seeds to absorb and grow. The tobacco seedling raising substrate in the prior art includes three ...

Problems solved by technology

[0003] In the prior art, the mixing operation of the three components by the staff is relatively rough, and most of them use tools such as shovels for manual mixing, or use equipment such as mixers for mixing. These two methods have certain disadvantages: whether it is vermiculite or puffed When perlite is used as a substrate component for tobacco seedling breeding, its particle size is small, and both have good water absorption effects. When mixed with a wet substrate, it is easy to quickly absorb water and form agglomeration, causing both Unable to mix e
