Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 4, as a preferred embodiment, the present invention provides an arbor assembly, which includes an arbor 10 having a cross-section of a regular polygon; set up with the interval a plurality of blade disc assemblies 20 on the axle 10, blade disc assembly 20 include with the blade disc body 21 that axle 10 is connected, blade disc body 21 have with the hole 22 of the cross section looks adaptation of axle 10, blade disc body 21 still has along a radial N cutting edge installation department 23 that stretches out, blade disc body 21's both sides all are provided with the concave station 24 that is used for installing the blade, detachable installation in the concave station 24 with the blade subassembly 25 of cutting edge installation department 23 looks adaptation.

In the present application, referring to fig. 2-7, depending on the usage environment and the materials to be cut, the blade assembly 20 can be combined in different ways, for example, the blade assembly 20 is an integral disc blade, the disc blade has N cutting edges adapted to the cutter head body 21, in this structure, the blade is a disc with N cutting edges, and the disc blade is positioned and installed through the concave platforms 24 at both sides of the cutter head body 21; another structural style is that the blade assembly 20 includes N separating blades, N separating blades are detachably connected with N cutting edge mounting portions 23 of the cutter head body 21, wherein after N separating blades are connected with the cutter head body 21, the N separating blades can be in a disc shape with mutual contact from head to tail, or in a centrifugal distribution without mutual contact, in the present application, the detachable connection of the blade assembly 25 and the cutter head body 21 aims to directly separate the blade assembly from the cutter head body without disassembling the whole chopping equipment when the blade assembly needs to be replaced due to wear, breakage, fatigue fracture and other situations, so that the replacement efficiency can be greatly improved, the replacement auxiliary time can be shortened, the unnecessary downtime can be reduced, and the use efficiency of the equipment can be improved; the cutter head locking device comprises a main shaft, a cutter head locking device, a main shaft locking device, a blade lifting main shaft, a blade locking device, a blade locking main shaft.

In the application, the cutter head body 21 and the shaft 10 can be connected in various ways, for example, the cutter head body 21 and the shaft 10 are detachably connected through screws, and when the detachable connection of the screws is adopted, the cutter head body is convenient to install for the first time; the other structural form is that the cutter head body 21 and the shaft 10 are integrally formed, and the structural form omits the installation step of the cutter head body 21 and the shaft 10, but has higher requirements on the processing technology; another structural style does cutter head body 21 with axle 10 interference fit rises to be connected, adopts interference fit to rise when rising, is not convenient for dismantle cutter head body 21 and axle 10, cutter head body 21 with axle 10 can also adopt splined connection, and the connected mode homoenergetic of above cutter head body 21 and axle 10 can reach the technical purpose of this application, can select according to service environment and the demand of difference.

In the present application, the cross section of the shaft 10 is one of a regular pentagon, a regular hexagon, a regular octagon, a regular decagon and a regular dodecagon, and the regular polygon structure of the shaft 10 is intended to transmit torque, so that on the premise of satisfying the use function, the cross section of the shaft 10 may be selected from any one of the regular polygon structural forms including but not limited to the above regular polygon structural form; in the present application, it is preferable that every two impeller assemblies 20 are spaced apart by the spacer 30, so as to ensure that the plurality of impeller assemblies 20 on the shaft 10 do not have lateral displacement on the shaft, and ensure the stability and reliability of the operation of the shredding device.

Preferably, referring to fig. 1, 2 and 8, in the present application, N cutting edge mounting portions 23 on the cutter head body extend in a clockwise or counterclockwise direction, in order to achieve the best cutting effect, when all the cutting edge mounting portions 23 extend in the same direction, the blade assembly 25 cuts in the same direction, so as to ensure the cutting efficiency, and at the same time, the cutter head assemblies 20 on the shaft 10 are installed in a staggered manner along the axial direction, preferably by forming a fixed angle α between the cutter head assemblies 20, for example, the angular displacement interval between every two adjacent cutter head assemblies 20 is set to be 5 °, 10 °, 15 °, 18 °, etc., so that the cutting action of the cutter shaft assembly is continuous along the axial direction when the cutter shaft assembly rotates, thereby reducing the unstable vibration during the cutting process.
