Description

A disc mower with adjustable width

技术领域：本实用新型涉及一种割草刀具，特别是指一种可调幅宽的圆盘割草刀。Technical Field: The utility model relates to a mowing knife, in particular to a disc mowing knife with adjustable width.

背景技术：现有的割草刀大多是固定双刃或圆盘刀，其幅宽是固定的。它不能根据草丛植被稀密长短及土质松软坚硬的具体情况来调整割草刀具的幅宽，从而不能充分利用现有的动力来提高生产效率。Background technology: Most of the existing lawn mowing knives are fixed double-edged or disc knives, and their width is fixed. It cannot adjust the width of the mowing cutter according to the specific conditions of the denseness of the grass vegetation and the softness and hardness of the soil, so that the existing power cannot be fully utilized to improve production efficiency.

发明内容：本实用新型的目的在于克服现有技术的不足，设计了一种结构简单、调整方便、成本低廉的可调幅宽的圆盘割草刀。Summary of the invention: The purpose of this utility model is to overcome the deficiencies of the prior art, and to design a disc mowing knife with adjustable width, simple structure, convenient adjustment and low cost.

一种可调幅宽的圆盘割草刀。包括有刀盘1、割草刀4及螺栓组 5。刀盘1的中间开有六方形的安装孔2；刀盘1上均匀分布地开有三个长型孔3；长型孔3上通过螺栓组5安装有割草刀4。Disclosed is a disc mower with adjustable width. Including a cutter head 1, a mowing knife 4 and a bolt group 5. There is a hexagonal mounting hole 2 in the middle of the cutter head 1; three elongated holes 3 are evenly distributed on the cutter head 1;

所述的割草刀4的刀刃加工有带曲线的刀锋。The blade of the mowing knife 4 is processed with a curved blade.

所述的割草刀4每一把通过两个螺栓组5固定。Each of the mowing knives 4 is fixed by two bolt groups 5 .

所述的螺栓组5包括有螺栓a、弹簧垫圈b、螺母c。The bolt group 5 includes a bolt a, a spring washer b, and a nut c.

拧松螺栓组5，把割草刀4沿着长型孔3移到合适位置然后再拧紧，从而达到调整割草幅宽的要求。Unscrew the bolt group 5, move the mowing knife 4 to a suitable position along the elongated hole 3 and then tighten it, so as to meet the requirement of adjusting the width of mowing.

综上所述：本实用新型的装置结构简单紧凑，调整使用安全方便，制造成本低。To sum up: the utility model has a simple and compact structure, safe and convenient adjustment and use, and low manufacturing cost.

附图说明：图1为本实用新型的主视图；图2为本实用新型的俯视图。Description of drawings: Figure 1 is a front view of the utility model; Figure 2 is a top view of the utility model.

具体实施方案：下面结合附图1、附图2进一步详细说明一种可调幅宽的圆盘割草刀的具体实施方式。Specific embodiments: the specific implementation of a disc mower with adjustable width will be further described below in conjunction with accompanying drawings 1 and 2 .

如图1、图2所示，一种可调幅宽的圆盘割草刀包括有刀盘1、割草刀4及螺栓组5。刀盘1的中间开有六方型的安装孔2；通过螺母可把刀盘1安装在六方形的动力轴上。刀盘1上均匀分布地开有三个长型孔3；在长型孔3上通过螺栓组5安装有割草刀4。所述的螺栓组5有螺栓a、弹簧垫圈b及螺母c。本实用新型的工作原理是：工作时，将刀盘1安装在动力轴上，并用螺母锁紧，然后拧松螺栓组5，将割草刀4移到长型孔3的合适位置，再拧紧螺母c。所述的割草刀4每一把通过两个螺栓组5固定。固定好割草刀4后，启动动力机，动力轴就可以带动刀盘1转动，这样就可以割草了。As shown in FIG. 1 and FIG. 2 , a disc mower with adjustable width includes a cutter head 1 , a mower 4 and a bolt group 5 . There is a hexagonal mounting hole 2 in the middle of the cutterhead 1; the cutterhead 1 can be installed on the hexagonal power shaft through nuts. Three elongated holes 3 are evenly distributed on the cutter head 1; mowing knives 4 are installed on the elongated holes 3 through bolt groups 5. The bolt group 5 includes a bolt a, a spring washer b and a nut c. The working principle of the utility model is: when working, install the cutter head 1 on the power shaft, and lock it with a nut, then loosen the bolt group 5, move the mowing knife 4 to a suitable position in the elongated hole 3, and then tighten it nut c. Each of the mowing knives 4 is fixed by two bolt groups 5 . After fixing the grass cutter 4, start the power machine, and the power shaft can drive the cutter head 1 to rotate, so that the grass can be mowed.

由于本实用新型结构简单可靠，生产效率高，制造成本低，且安装使用安全方便，因此具有广阔的市场前景。Because the utility model has simple and reliable structure, high production efficiency, low manufacturing cost, and safe and convenient installation and use, it has broad market prospects.
