Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to a harvester blade which is easy to replace. Background Art

[0002] A harvester is a mechanical device that plays an important role in agricultural production. It is mainly used to harvest crops such as wheat, rice, corn, etc. The emergence of harvesters has greatly improved the efficiency of agricultural production and reduced the labor intensity of farmers. Different types of harvesters have different characteristics and applicable scenarios. For example, small harvesters are suitable for small farmlands and complex terrains, while large combine harvesters are suitable for large-scale plain farmland operations.

[0003] However, at present, the common harvester blades on the market have some shortcomings in terms of replacement. Traditional harvester blades are usually installed on the blade holder by bolts and other fixing methods. Special tools are required for replacement, and the operation process is cumbersome, time-consuming and laborious. This not only increases the labor intensity of farmers, but may also affect the farming time due to the long replacement time. The blade fixing structure of some harvesters is complex and the number of bolts is large. Bolts are easily lost or damaged during the disassembly and installation process. Moreover, due to the harsh working environment, bolts are prone to rust, which further increases the difficulty of replacement. For this reason, we provide a harvester blade that is easy to replace.

[0026] The fixing assembly 2 includes: a control panel 21, a surface of a rotating disk 32 is fixedly mounted on the control panel 21, a plug rod 22 is fixedly mounted on the bottom of the control panel 21, a positioning rod 23 is hinged on the surface of the plug rod 22, one end of a torsion spring 24 is fixedly mounted on the surface of the plug rod 22, the other end of the torsion spring 24 is fixedly mounted on the inner side of the positioning rod 23, and a positioning plate 25 is fixedly mounted on the inner side of the fixing ring 31. When the control panel 21 is pressed downward, the plug rod 22 and the positioning rod 23 will move in the same active direction as the control panel 21. When the positioning rod 23 moves, it will penetrate the positioning plate 25. After the positioning rod 23 penetrates the positioning plate 25, the positioning rod 23 will be fixed on the torsion spring 2 4, so that it is reset under the action of the positioning plate 25, thereby being clamped at the bottom of the positioning plate 25 for restriction, thereby improving the stability and fixing effect of the installation of the blade 6.
