A grass cutting head with a convenient winding structure

Abstract

The invention discloses a grass collecting head with a convenient winding structure. The grass collecting head comprises a base, an upper cover, a thread spool, and a mowing thread wound on the thread spool, wherein the base is clamped with the upper cover; the thread spool is assembled between the base and the upper cover; a thread clamping groove is formed in the thread spool; two ends of the mowing thread extend out of a thread outlet hole of the upper cover; a fixing ring is arranged in the center of the upper cover; a knob is arranged on the outer side of the upper cover and is matched with the fixing ring; a large compression spring is arranged between the knob and the upper cover; a screw is arranged in the center of the fixing ring and is fixed with the knob; a screw washer is arranged between the screw and the fixing ring; and a small compression spring is arranged between the screw washer and the thread spool. The grass collecting head with the convenient winding structure, disclosed by the invention, has the advantages that the structure is simple, the upper cover and the thread spool form a whole, winding is convenient and rapid, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a mowing head with a convenient winding structure. Background technique [0002] The lawn trimmer is a common garden tool. Its main principle is to use a motor or an engine to drive the mowing head to rotate at a high speed, and to use the cutting line wound on the center axis of the mowing head to cut the grass. When the cutting wire protruding out of the trimming head housing breaks or becomes worn, a new cutting wire must be released from the spool, and when the cutting wire on the spool has been released, a new cutting wire needs to be rewound. thread; when winding the cutting wire with the trimming head on the market, it is often necessary to disassemble the trimming head, take out the spool and then wind it, which is very inconvenient and affects the work efficiency to a large extent. [0003] Existing patent No. is 201420384972.0 and the patent titled "a kind of ...

AI Technical Summary

Problems solved by technology

When the cutting wire protruding out of the trimming head housing breaks or becomes worn, a new cutting wire must be released from the spool, and when the cutting wire on the spool has been released, a new cutting wire needs to be rewound. thread; now when the cutting head on the market is winding the cutting line, it is often necessary to disassemble the cutting head, take out the spool and then wind it, which is very inconvenient and affects the work efficiency to a large extent

[0003] Existing patent No. is 201420384972.0 and the patent titled "a kind of grass-cutting head" discloses a kind of grass-cutting head, which includes a grass-cutting head cover, a grass-cutting head seat and a winding core, and the described grass-cutting head cover is connected Grass cutting head seat, the winding core is located in the grass cutting head seat, the grass cutting head cover includes a rivet-shaped metal cover, bearings, plastic seats and springs, and the shaft below the rivet-shaped metal cover is divided into an upper shaft And the lower shaft, the length of the lower shaft is shorter than the upper shaft, the lower shaft is tightly connected with the inner hole of the bearing, and the bearing is fixed in the center of the plastic seat on the grass cutting head cover; this grass cutting head has the problem of difficulty in threading, and it is difficult to wind new lines At this time, the mowing head cover needs to be opened, and the internal parts will be scattered all over the place. After the winding is completed, they need to be reassembled together, which is very troublesome, so its structure needs to be further improved.
