Embodiment Construction

[0033] like figure 1 As shown, the present invention consists of three parts: teeth, tooth grooves and tooth backs; the teeth are composed of cutting parts, extension parts, chip removal parts and embedded angles, and the cutting parts are composed of main cutting edge EFH, secondary cutting edge e'f' h' and the leading cutting edge e"f"h", the main cutting edge EFH, the auxiliary cutting edge e'f'h' and the leading cutting edge e"f"h" are parallel to each other; The extension edge Ee' and the secondary extension edge e'e” are composed; the chip removal part is composed of the chip removal edge EJV and the chip guide edge e”jv, the chip removal edge EJV and the chip guide edge e”jv are both parallel, and the embedded angle α is The angle between the main cutting edge EFH and the chip removal edge EJV.

[0034] The main extension edge Ee' is a straight line connecting the main cutting edge EFH and the auxiliary cutting edge e'f'h', and the auxiliary extension edge e'e" is the ...

Abstract

The invention discloses a bionic sawtooth-shaped structure and belongs to the technical field of agricultures. The bionic sawtooth-shaped structure is composed of teeth, tooth spaces and tooth backs; each tooth is composed of a cutting part, an edge extension part, a chip removal part and an embedded angle. The bionic sawtooth-shaped structure is high in sawing speed and capable of increasing the single tooth embedded depth, saving more labor during sawing and better collecting, storing and discharging chips; due to the adoption of a bionic design of graded cutting, the cutting speed can be increased and the cutting force can be reduced on the basis that the tooth strength is guaranteed; the tooth spaces can be used for better cleaning saw lines and increasing the cutting efficiency; and the teeth and the tooth spaces can take effects only under tooth back supporting and force transferring actions.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and particularly relates to a bionic zigzag structure. Background technique [0002] The zigzag structure has the characteristics of wide application range, simple structure, low cost, convenient operation and high efficiency. Nowadays, the zigzag structure can be seen everywhere in forestry, agriculture, industry, construction, manufacturing and other industries and in life. An irreplaceable role in production and life. [0003] The sawtooth structure is widely used in forestry, such as double saws and chainsaws for logging, circular saws and wood saws for processing wood, garden saws for pruning branches, hacksaws for metal processing in industry, and other types of saws used in daily life. Hand saws, folding saws, and even surgical saws for amputations are all serrated structures. [0004] In recent years, the sawtooth structure has been used more and more in agriculture. The cutting dis...
