Along with the improvement of living standard of people, the output of garbage is increased day by day, and the problem of garbage recycling treatment is increasingly serious. Currently, the crushing treatment of garbage by crushing blades is the main operation mode of garbage recycling treatment, especially in the field of food garbage treatment.

Meanwhile, the crushing blades are also widely used in home appliances, such as juicers, meat grinders, cooking machines, etc., for cutting and crushing food.

However, the current crushing blades have a single structure and are mostly flat linear blades or serrated blades with connected blades. Since the hardness, texture, and the like of the object to be treated are very different, the crushing blade is easily subjected to high-strength impact when crushing a large-size and high-hardness substance, and thus problems such as edge curling and chipping easily occur.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 2, the present invention provides a crushing blade, including a blade body 1 and a cutting surface 3 formed on one side of the blade body, wherein the cutting surface 3 is a crushing operation surface of the crushing blade for crushing food or garbage; the structure of the cutting surface 3 is as follows: the cutting device comprises a first cutting edge 211 and a second cutting edge 221 which are adjacently arranged, wherein the first cutting edge 211 and the second cutting edge 221 form a cutting group 2, and a plurality of cutting groups 2 are sequentially arranged on a cutting surface 3; the second cutting edge 221 is recessed relative to the first cutting edge 211, and the second cutting edge 221 has a cutting edge and is sharper relative to the first cutting edge 211; the first cutting edges 211 arranged at intervals form the first cutting groups 21, and the second cutting edges 221 arranged at intervals form the second cutting groups 22.

In the invention, the first cutting group 21 which is relatively convex strikes the point surfaces which form clusters on the object to be processed, the point surfaces strike the object to be processed, the point surfaces have a hammering effect, and the high-hardness substance is easy to be cracked into a plurality of small individuals with equal or not different sizes by using the striking force. Is further comminuted by the second cutting edge when the aforesaid small individual size is small enough to enter the recess in which the second cutting edge is provided. So set up, first cutting edge 211 can realize the hammering effect, and second cutting edge 221 only is responsible for handling the pending thing that is less than sunken size, and two sets of cutting edges have carried out the cutting and have divided the labour, have improved the crushing ability of smashing the blade.

Because the second cutting edge 221 is set to be relatively sharper, the hard garbage is more easily and rapidly and gradually ground and cut by chopping and cutting, the overall size of the hard garbage is smaller and smaller, and the overall crushing efficiency of the blade is improved. Meanwhile, the second cutting edge 221 is concavely arranged on the cutting surface 3, so that the second cutting edge is not impacted by large-size objects to be processed, quality problems such as edge rolling, opening cracking and the like caused by the relatively sharp second cutting edge 221 can be effectively avoided, and the service life of the blade is prolonged. In addition, the chopping and cutting actions of the relatively sharp second cutting edge 221 are more beneficial to processing flexible substances such as fruits and vegetables, rubber, reed leaves and the like, and the capability of comprehensively processing hard and soft substances by the blade is improved.

The accumulated length of the cutting lines of the first cutting group 21 is the sum of the lengths of the cutting lines 2110 of all the first cutting edges 211; the accumulated cutting line length of the second cutting group 22 is the sum of the cutting line lengths 2210 of all the second cutting edges 221; the first cutting edge cutting line 2110 is an arc length of a cutting surface of the first cutting edge 211 participating in the crushing operation; the cutting line 2210 of the second cutting edge 221 is the arc length of the cutting surface of the second cutting edge 221 participating in the pulverizing operation. The longer the accumulated cutting line length of the second cutting group 22, the longer the cutting surface thereof participating in the crushing work, and the stronger the ability thereof to crush small particulate matter. The longer accumulated cutting lines of the second cutting group 22 are for the crushing blades to have a stronger ability to handle small particle materials, and since the larger number of particles is larger after the large size materials are crushed, the crushing blades are required to have a stronger fine crushing ability accordingly, thereby improving the crushing ability of the whole crushing blades as a whole.

Referring to fig. 3 and 4, in one embodiment, the concave shape of the second cutting edge 221 is an arc, the second cutting edge 221 is a serrated edge 2211, the number of the serrated edges 2211 is at least three, and all the serrated edges 2211 are uniformly arranged along the concave arc surface. The arc-shaped recess is beneficial to prolonging the arc length of the recessed crushing operation surface, so that more sawtooth edges 2211 can be arranged, and the cutting efficiency is improved. In addition, the serrated edge 2211 has a biting function and a better crushing effect than a straight cutting edge.

Alternatively, the plurality of serrated edges 2211 may have any tooth shape and size.

Optionally, the cutting edge of the serrated edge 2211 is sharpened by grinding, so that the thickness of the cutting edge is reduced, the sharpness of the cutting edge is improved, and the cutting and crushing efficiency of the cutting edge is improved.

Optionally, the first cutting edge 211 is an arc-shaped non-sharp edge.
