Plastic covered agricultural implement and forming method thereof

Abstract

The invention relates to a plastic covered agricultural implement and a forming method thereof. The plastic covered agricultural implement comprises a handle, the handle comprises a handle core made from solid wood, wood plywood or bamboo plywood; a plastic layer is wrapped on the outer surface of the handle core; besides, a hand-held steel framework formed by steel bars is installed on one end of the handle core; and a high strength plastic layer is integrally injected and molded on the outer surfaces of the handle core and the hand-held steel framework. The handle of the plastic covered agricultural implement provided by the invention is completely sealed, is waterproof, and prevents such phenomena as moisture regain, mustiness, worm damage and crack; the integral handle has the test tension of larger than 180 KG and test pressure of larger than 280 KG which are more than twice larger than the test tension and the test pressure of the handle made from solid wood, wood plywood or bamboo plywood and are more than 1.5 times larger than the test tension and the test pressure of a plastic covered handle with a steel pipe or a fiber bar as an inner core; the surface is smooth and the hand feel is tender; the surface is not treated by using paint, the yield is 95-100%, and the service life of the handle of the plastic covered agricultural implement is prolonged by more than two times.

Description

technical field [0001] The invention relates to the technical field of tool handles, in particular to a plastic-coated agricultural tool and a molding method thereof. Background technique [0002] At present, many tools are complete tool sets that are assembled after the iron parts and the handle parts are manufactured separately. Among them, agricultural tools with wooden handles such as steel shovel, steel shovel, steel pick, steel rake, steel hoe, hammer, sickle, etc. are represented. Most of the handles used by such tools use round solid wood handles, and there are also small ones. Part of it is a round handle made of composite materials such as wood plywood and bamboo plywood, and then a layer of paint is applied to the surface of the handle. Among them, some tools are equipped with plastic or iron handshakes at the end of the handle and are sold and used as complete sets of tools with steel shovel heads and the like. [0003] The tool handles produced by the above-me...

AI Technical Summary

Problems solved by technology

[0003] The tool handles produced by the above-mentioned process are prone to moisture regain, mildew, insects, and breakage, and the precision of solid wood surface treatment is very high, and the defective rate is very high (generally below 70% of the finished product rate)

After testing, the overall tensile test of this tool handle and plastic and iron handshakes is between 60-80KG, and the pressure test is between 100-120KG. The product quality level is low, and there is a serious waste of raw materials.
