Embodiment 1

[0037] The power shaft 1 is the output shaft of the motor, and the wire crimping sleeve 6 has a cutting wire cover, such as Figure 4 shown.

Embodiment 2

[0039] The power shaft 1 is the output shaft of the motor, the wire crimping sleeve 6 does not have a cutting wire cover, the number of axial grooves 9 on the bobbin cylinder 4 is 6, and the number of cutting wires 7 is 3, such as Figure 5 shown.

Embodiment 3

[0041] The power shaft 1 is the output shaft of the motor, the wire crimping sleeve 6 does not have a cutting wire cover, the number of axial grooves 9 on the bobbin cylinder 4 is 12, and the number of cutting wires 7 is 6, such as Image 6 shown.

[0042] When assembling, first, pass the inner hole of the fixed screw sleeve 5 and the crimping sleeve 6 through the motor shaft, then connect the bobbin cylinder 4 with the motor shaft through a flat key or a spline, and then pass through the shaft shoulder of the motor shaft and The baffle plate 2 and the connecting screw 3 realize the axial positioning and fixing of the motor spindle and the bobbin cylinder 4; then the cutting line 7 passes through the hole at the bottom of the bobbin cylinder 4 and the hole 8 on the radially opposite side, and then the cutting line 7 Place them in the axial grooves 9 of the spool cylinder 4 at intervals, and make the axial height the same as the height of the spool cylinder 4; In the axial gro...

Abstract

The invention discloses a reel-free grass cutter head, which comprises a power shaft, a bobbin cylinder, a fixed barrel, a line pressing sleeve and a cutting line, wherein the power shaft is arranged on a rack of a grass cutter fixedly; the bobbin cylinder is a hollow frustum with the trapezoidal cross section; a central hole is formed in the center position of a flat plate at the upper part of the hollow frustum; the central hole is fit with the power shaft and is arranged fixedly on the power shaft; the lower part of the hollow frustum is provided with a convex step; the outer edge of the step is provided with a boss; the line pressing sleeve is a round sleeve; the line pressing sleeve is sleeved outside the middle-lower side wall of the bobbin cylinder; the fixed barrel is a barrel with inner threads and is arranged on the upper part of the hollow frustum of the bobbin cylinder through threads, and the lower edge of the fixed barrel is connected with the upper edge of the line pressing sleeve; one end of the cutting line is arranged on the step at the lower part of the hollow frustum of the bobbin cylinder while the other end is a free end; the cutting line is pressed on the step at the lower part of the hollow frustum of the bobbin cylinder through the line pressing sleeve. The reel-free grass cutter head has the advantages that the structure is simple, fewer parts are used, assembly and disassembly are convenient, the manufacturing cost is low, the cutting efficiency is high, the operation and maintenance operation is simple, and the failure rate is low.

Description

technical field [0001] The invention belongs to the technical field of mowing machinery and equipment, and in particular relates to lawn care, pruning and mowing machinery and equipment, in particular to a mowing machine head. Background technique [0002] The invention patents published by the State Intellectual Property Office of the People's Republic of China "A Lawn Mower" (Patent No.: 200910180677.7), "Rotary Cutter for Lawn Mower" (Patent No.: 200980103570.0), "Rotary Cutter for Lawn Mower "(Patent No.: 201080058938.9), "Lines for Lawn Mowers" (Patent No.: 201080001286.5) and "Wire Trimmer" (Patent No.: 201310086285.0) disclose several lawn mowers and mower heads, A common feature of these mower heads is the reel around which the cutting line is wound. Its disadvantages are: due to the reel winding the cutting wire, the structure is complex, the number of parts is large, and the manufacturing cost is high. Contents of the invention [0003] The purpose of the prese...
