Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 As shown, the blade of this embodiment includes a knife plate 1, the knife plate 1 is a blade-shaped structure provided with a central axis hole 11, and several circumferentially distributed punching pins are integrally formed on the outer edge side of the knife plate 1 2. The front part of the perforating needle 2 is a tubular structure 22 with a small head diameter and a large tail diameter, and a certain taper. The taper angle is 1-4°. There is a cutting edge 21 at the top, which can help cut into the soil and reduce the pressure of punching; the inner end of the middle and rear part of the perforating needle 2 is connected with the outer edge of the knife plate 1, preferably tangentially arranged, and the outer end is bent to form The tile-shaped structure 23 with an arc-shaped cross section is preferably a semicir...

Provided is a blade and a manufacturing method thereof. The blade is characterized in that the blade comprises a cutting board, the cutting board is in a fan blade structure with a central axle hole. One side of the outer edge of the cutting board is integrally provided with a plurality of punching pins distributed in a ring direction. The inner end of the middle-rear portion of the punching pin is connected with the outer edge of the cutting board, and the outer end bends to form a tile shaped structure whose section is in an arc shape. The front part of the punching pin is a hollow tubular structure. The head of the tubular structure is provided with a cutting edge. The blade is pressed by using a steel plate, and is rolled to make an integrated piece. The front part of the punching pin is in a tubular structure with conicity, being beneficial for soil to discharge, the head of the tubular structure is provided with the cutting edge, providing convenience for reducing pressure for cutting in soil. The middle-rear portion of the punching pin is in a tile shape, and the tail is provided with a dip angle turning to backward, so soil guided from the head of the punching pin can be discharged in time, and would not stack to cause blocking. The blade is simple in structure and convenient in manufacturing and processing, and the blade can be installed on a scarifier to puncture a lawn, thereby greatly saving materials and installing procedures, and cost of the blade is relatively low.
Description
technical field [0001] The invention belongs to the technical field of garden tools, in particular to a blade for punching lawns and a preparation method thereof. Background technique [0002] Due to factors such as trampling by humans and animals and natural hardening of garden lawns, the soil crispness of the lawn will be reduced, and the oxygen content in the soil will also be insufficient, which will affect the normal growth of the turf. Therefore, places with higher requirements for lawn quality, such as golf courses, will use professional lawn aerators for hole care. Because the expense of nursing is higher, thereby the lawn of common family can not get this patent nursing because of the reason of expense. [0003] The punching tool of the existing lawn punching machine is generally composed of multiple punching pins, each punching pin needs to be professionally installed and fixed, the assembly cost is relatively high, and the punching pins are generally made of stee...
