Abstract

The invention relates to a clamping device for rapidly replacing cutting blades, which comprises a sample fixing mechanism, a movable cutter adjusting mechanism and a fixed cutter adjusting mechanism. Thickness, tooth shape and the like of a movable cutting blade and a fixed cutting blade are optionally selectable, and an open angle between the movable cutting blade and the fixed cutting blade isvariable along with different replaced positioning blocks. The distance between the sampling fixing mechanism and each of the movable cutter adjusting mechanism and the fixed cutter adjusting mechanism can be adjusted according to the sample length, and then the sampling fixing mechanism, the movable cutter adjusting mechanism and the fixed cutter adjusting mechanism can be fixed onto an operation table of a universal testing machine with a T-shaped groove through bolts for the T-shaped groove. Using the clamping device can conveniently solve the problem of influences of factors such as thickness and sliding cutting angle of the cutting blades, the open angle between the cutting edges of a movable cutter and a fixed cutter, different cutting edge shapes and the like on cutting performanceof the cutting blades. Further, the clamping device for rapidly replacing cutting blades has the advantages of simple structure, easiness in mounting, convenience and rapidness in cutting blade adjustment, safety, reliability and the like.

Description

(1) Technical field

[0001] The invention relates to a clamping device capable of quickly replacing cutting blades, which belongs to the field of agricultural machinery and equipment. (2) Technical background

[0002] Crop stalks are an important biological resource in crop production systems. In recent years, with the sharp increase in the demand for biomass raw material products such as animal feed, high-quality paper products, and fuel alcohol, crop stalks have been widely developed and utilized. The shape characteristics of the stalks of rice, wheat and other crops are soft and thin. Compared with these crops, the shape characteristics of the stalks of cotton, sugarcane, reed bamboo, corn and other crops are different due to their different biological characteristics and growth mechanisms. It is obviously hard and thick, and the hardness and rigidity of the stalks are large, such as cotton stalks with a diameter of 25 mm, sugarcane stalks with a diameter of 50 mm, and ree...
