Mortise-tenon type rubber farmland cofferdam plate

Abstract

The invention relates to a cuboid mortise-tenon type rubber farmland cofferdam plate which is the substitute of a traditional soil cofferdam. The mortise-tenon type rubber farmland cofferdam plate ismanufactured by cooperatively using raw rubber (mainly regenerated rubber) and corresponding chemical fibers (mainly nylon fibers) and adding rubber auxiliaries, the cofferdam plate can be bent at will to form special shapes, the cofferdam plate can be produced by waste rubber in actual production, and the aged cofferdam plate can be recycled after smelting and be produced into a new cofferdam plate or other rubber products. The mortise-tenon type rubber farmland cofferdam plate has two reinforcing support wedges in the middle, the deformation torsion of the cofferdam plate is enhanced, and the stability of the cofferdam plate during use is guaranteed. Two mortise-tenon type rubber farmland cofferdam plates are connected through double inverted-n-shaped rubber mortise-tenon joints in a clamped manner, the inverted-T-shaped parts and the inverted-n-shaped parts are exactly integrally engaged with each other during connection, screws can be used for fixation when necessary, and firm andtight connection is achieved.

Description

technical field [0001] The invention relates to a cofferdam device used for water isolation in farmland seedling raising operations, in particular to a recycling device. Background technique [0002] In the existing farmland seedling raising operations, the water in the seedling ponds uses soil cofferdams. Due to the poor air tightness of the soil and the high water absorption of the soil itself, the leakage and loss of seedling raising water are very serious. The existing operation methods have caused precious water A huge waste of resources. [0003] At the same time, the cost of repairing and maintaining the soil cofferdam is high, the labor time is long, and the soil cofferdam itself is easy to breed weeds. All these reasons lead to high energy consumption, serious waste, and high labor intensity. The disadvantages are obvious. In addition, the application and residues of herbicides and other pesticides cause serious pollution to crops, and the damage to the environment...
