Embodiment Construction

[0053] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] Please refer to Figure 1-3 , Figure 7-10 , the structure of the chain knife is as follows: the upper chain knife 1 is mainly composed of a chain and a group of upper chain knife blades 40 riveted on the chain upper chain knife outer plate 41, which surrounds the upper chain knife driving sprocket 20 and the upper chain knife driven The sprocket 3 is arranged; the lower chain knife 22 is mainly composed of a chain and a group of lower chain knife blades 39 riveted on the outer plate 38 of the chain lower chain knife, which surrounds the lower chain knife driving sprocket 33 and the lower chain knife driven sprocket 23 arrangements. Moreover, the distance between adjacent chain knife blades 40 on the chain knife 1 is the same as the width of one chain knife blade 40 , and the structure of the bot...

Abstract

The invention belongs to the technical field of agricultural machineries, specifically to a chain-type double knife cutter for a mower, which has the advantages of high speed like rotary mower and low consumption like reciprocating mower, small vibration, low noise and stable cutting, comprising an upper chain knife (1) and a lower chain knife (22), wherein one end of the upper chain knife (1) surrounds a driving sprocket (20) of the upper chain knife to be located; the other end surrounds a driven sprocket (3) of the upper chain knife to be located; one end of the lower chain knife (22) surrounds a driving sprocket (33) of the lower chain knife to be locate; the other end surrounds a driven sprocket (23) of the lower chain knife to be located; the driving sprocket (20) of the upper chainknife is connected with a left input shaft (21); the driven sprocket (23) of the lower chain knife is supported on the left input shaft (21); the driving sprocket (33) of the lower chain knife is connected with a right input shaft (2); the driven sprocket (3) of the upper chain knife is supported on the right input shaft (2); the rotation directions of the left input shaft (21) and the right input shaft (2) are opposite and the rotation speeds are the same.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a chain-type double-moving knife cutter for a lawn mower. Background technique [0002] At present, there are mainly two types of reciprocating and rotary lawn mowers. Reciprocating lawn mowers are widely used due to their simple structure and low cost. speed, so the working speed is low; although the rotary lawn mower does not have the inertial force of the reciprocating lawn mower, the cutting speed and working speed are much higher than the reciprocating lawn mower, but the rotary lawn mower adopts serial gear transmission. It is relatively high, and the power consumption per unit cutting width is large. In order to eliminate the inertial force of the reciprocating lawn mower and increase the speed of the reciprocating lawn mower, the driving device of the reciprocating lawn mower has gradually changed from a crank linkage mechanism to a crank swing...
