Description

The cutter head of mower

The utility model relates to a kind of electric tool.

Along with society and expanding economy, people's environmental consciousness is more and more higher, and the meadow, lawn has entered in our life in large quantities, and therefore, mower has also obtained using widely.Existing mower is equipped with the strip blade in the bottom of rotating shaft, the high speed rotary motion that is roughly parallel to ground by the strip blade prescinds too high careless class, if but blade is when running into hard objects such as stone when mowing, just be easy to damage blade or produce spark even have an accident, therefore, it exists some hidden danger aspect security performance.

The purpose of this utility model is: the cutter head that a kind of mower is provided, this device is installed in the blade flexibility on the cutterhead, mow by the rotating shaft rotating cutter-head, so blade is difficult for running into stone, can not damage blade yet or produce spark even run into stone, thereby improve the security performance of mower greatly.

The technical solution of the utility model is: a kind of cutter head of mower, this device comprise that the center is installed in the cutterhead of mower roller end, and the edge of cutterhead is evenly equipped with several pins, is with blade on the pin.

The further technical scheme of the utility model is: a kind of cutter head of mower, this device comprise that the center is installed in the cutterhead of mower roller end, and the edge of cutterhead is evenly equipped with several pins, is with blade on the pin; The cutting edge of described blade is the arc of evagination; The lower plane of described cutterhead curved recessed the contracting that make progress; Described pin is the T font, the diameter of head is greater than the diameter of neck, described blade is provided with looping pit, looping pit is partially overlapped by an aperture and a macropore and forms, and aperture and macropore are arranged along the diametric(al) of cutterhead, and aperture is positioned near the cutterhead center of circle one side, the diameter of aperture is less than the diameter of T shape pin head, the diameter of macropore is greater than the diameter of T shape pin head, the diameter of the openings of sizes T shape pin neck of aperture and macropore intersection, and the height of T shape pin neck is slightly larger than the thickness of annular distance.

The more detailed technical scheme of the utility model is: a kind of cutter head of mower, this device comprise that the center is installed in the cutterhead of mower roller end, and the edge of cutterhead is evenly equipped with several pins, is with blade on the pin; The cutting edge of described blade is the arc of evagination; The lower plane of described cutterhead curved recessed the contracting that make progress; Described pin is the T font, the diameter of head is greater than the diameter of neck, described blade is provided with looping pit, looping pit is partially overlapped by an aperture and a macropore and forms, and aperture and macropore are arranged along the diametric(al) of cutterhead, and aperture is positioned near the cutterhead center of circle one side, the diameter of aperture is less than the diameter of T shape pin head, the diameter of macropore is greater than the diameter of T shape pin head, the diameter of the openings of sizes T shape pin neck of aperture and macropore intersection, and the height of T shape pin neck is slightly larger than the thickness of annular distance; The neck of described pin is the boss that the cutterhead edge is provided with, and head is the packing ring that places the boss top, and the boss center is provided with the hole, is provided with rivet in the hole packing ring is fixed.

The utility model has the advantages that:

1. blade of the present utility model is not the bottom that is directly installed on rotating shaft, and be mounted in the edge of cutterhead, cutterhead is fixed on the rotating shaft lower end, by rotating cutter-head blade is mowed, so the cutterhead that rotates can be removed the hard objects such as stone that may exist on the meadow.

2. blade of the present utility model is enclosed within on the pin of cutterhead edge setting, and the cutting edge of blade is outer convex, so even blade contingency is run into hard objects such as stone, blade can turn over certain angle and get out of the way, rather than with the very stiff and demanding collision of stone, thereby also can avoid damaging and producing spark.

3. blade of the present utility model is provided with looping pit, it is very convenient to install, as long as the macropore of looping pit is inserted in the pin, and then broach for external bracing sheet, pin is entered in the aperture of looping pit, and blade just can not come off, during use, the cutterhead high speed rotating, blade more can not come off under action of centrifugal force.

The utility model will be further described below in conjunction with drawings and Examples:
