Description

Technical Field

[0001] The utility model relates to the technical field of pulverizer blades, in particular to an adjustable-distance blade group. Background Art

[0002] A crushing machine is a machine that uses mechanical force to crush solid materials into small pieces, fine powder or powder. A crushing machine is a general term for crushing machines and grinding machines. The crusher blade is a device used on the output shaft of the crusher and is mainly used to crush solid materials. The effect of crushing objects is achieved through the cutting and crushing of the blade.

[0003] At present, when the crusher blade group is in use, the drive shaft drives the cutter disc to rotate, and the cutter disc drives the blade to crush the material. The distance between two adjacent cutter discs cannot be controlled, and the distance between the blades cannot be adjusted according to the different crushed materials, which affects the crushing efficiency of the crusher.

[0004] After searching, the Chinese patent with application number CN202222597005.X proposes an adjustable-distance blade group, including a driving shaft, on which are sleeved blade discs arranged at equal distances, and a circularly distributed slider is fixedly connected to the right side of the blade disc, and a circularly distributed slide groove is provided on the driving shaft, and the inner wall of the slide groove is slidably connected to the slider, and a locking rod threadedly connected to the slider is inserted on the slider, and the slider and the slide groove can be unlocked and fixed by rotating the locking rod. However, this fixing method is relatively cumbersome, and each locking rod needs to be rotated, and the side sliding of the blade disc cannot be guaranteed by fixing the locking rod by tightly contacting the inner wall of the slide groove during use.

[0008] Preferably, the stopper is provided with a second hole groove matching the fixing rod; and the middle of the stopper is provided with a second connecting groove matching the driving shaft.

[0009] Preferably, crushing teeth are connected to the outer side of the stopper.

[0010] Preferably, the stopper is cylindrical; a connecting groove three matching the drive shaft is provided in the middle of the stopper; and the stopper is connected to the drive shaft through the connecting groove three.

[0011] Preferably, the stopper is cylindrical; the stopper is provided with a hole slot three matching the fixing rod; the stopper is connected to the fixing rod through the hole slot three.

[0012] Preferably, the blade comprises a first curved surface and a second curved surface; the first curved surface and the second curved surface form a cutting end.

[0013] Preferably, a shock-proof gasket is connected to the inner side of the fixing frame.

[0014] Preferably, both ends of the fixing rod are provided with external threads; both ends of the fixing rod are threadedly connected to limiting blocks; and the limiting blocks are arranged on the outside of the fixing frame.

[0015] Compared with the prior art, the utility model provides an adjustable-distance blade set, which has the following beneficial effects:

[0016] The adjustable-distance blade assembly changes the distance between the blade discs by arranging blocks between the blade discs, and arranges stirring teeth at the outer ends of the blocks, which can adapt to different usage conditions in conjunction with the blade discs, and changes the connection relationship between the blocks and the blade discs by arranging fixed rods. When the working strength of the blade discs is high, the blocks can be connected to the drive shaft and the fixed rod at the same time to enhance the stability between the blade discs. When the working strength of the blade discs is low, the blocks can be connected to the drive shaft or the fixed rod separately to reduce the overall load-bearing capacity.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
