DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to solve the problems of low efficiency, large crushed particles, difficult replacement of crushing blades, low stability and safety of the device under high-speed rotation and easy damage of blades in the existing technology when crushing wood waste, please refer to Figure 1-7 , this embodiment provides the following technical solutions:

[0030] A high-frequency crushing tool for processing wood waste includes a rotating shaft 1, and a plurality of crushing blades 2 are arranged and installed on the outer wall of the rotating shaft 1. One end of the crushing blade 2 is engaged with the rotating shaft 1 through a mortise and tenon assembly 3. A diverter assembly 4 is installed on the top surface of the rotating shaft 1, and a crushing barrel 5 is provided on the outer periphery of the crushing blade 2.

[0031] Specifically, the bottom of the rotating shaft 1 is installed on the output end of the adjusting rotating motor. The rotating motor drives the rotating shaft 1 to rotate at high speed, and the rotating shaft 1 correspondingly drives the crushing blade 2 to rotate at high speed. The crushing blade 2 crushes the wooden waste put into the crushing barrel 5 during the high-frequency rotation process; the crushing blade 2 and the rotating shaft 1 are connected by the mortise and tenon assembly 3. While ensuring the stability of the connection, a certain movable gap is also left to cope with the thermal expansion and contraction effect, and to a certain extent absorb the impact force of the wooden waste on the crushing blade 2, so that the device can maintain the stability of the overall operation under high-frequency rotation.

[0032] In this embodiment, a first cutting edge 21 is provided at the top of the crushing blade 2, and a row of triangular cutters 22 are provided on the concave surface of the crushing blade 2. The tip of the triangular cutter 22 faces the rotation direction of the crushing blade 2, and a second cutting edge 221 is provided on both sides of the tip. A retaining piece 24 is also fixed on the concave surface of the crushing blade 2, and the retaining piece 24 abuts against the convex surface of the adjacent crushing blade 2; the longitudinal cross-section of the crushing blade 2 is an arc, and the cross-sectional curvature of the crushing blade 2 from the inside to the outside changes from large to small, and the inner concave side of the arc faces the rotation direction of the crushing blade 2.

[0033] Specifically, the crushing blade 2 rotates clockwise when viewed from top to bottom. The first blade 21 cuts and crushes the wood waste, passes through the triangular cutter 22 during the falling process, and the second blade 221 further crushes the preliminarily crushed wood; since the crushing blade 2 has a certain curvature and twisting angle, the crushing blade 2 will generate a vertical downward airflow during the high-speed rotation process, so that the crushed wood fragments will not float around in the crushing barrel 5, but will be directly carried by the airflow into the discharge port below the crushing blade 2, thereby not only improving the crushing efficiency, but also improving the working environment; the provision of the stop piece 24 can maintain a fixed spacing between the crushing blades 2.

[0034] In this embodiment, a clamping assembly 23 is provided at one end of the crushing blade 2 connected to the rotating shaft 1, and the clamping assembly 23 includes an arc-shaped fixing piece 231 and a convex strip 232. The crushing blade 2 is fixed on the outer convex surface of the arc-shaped fixing piece 231, and the convex strip 232 is fixed on the inner concave surface of the arc-shaped fixing piece 231; the outer peripheral surface of the rotating shaft 1 is milled with mounting grooves 11 equal to the number of the crushing blades 2, and a clamping block 12 is provided between the mounting grooves 11. The bottom of the clamping block 12 is welded to the top surface of the rotating shaft 1, and the mounting groove 11 is adapted to the convex strip 232. One end of the crushing blade 2 is clamped in the mounting groove 11 through the convex strip 232, and the inner concave surface of the arc-shaped fixing piece 231 fits into the outer peripheral surface of the rotating shaft 1; the mortise and tenon assembly 3 includes an L-shaped clamping strip 31 and a fan-shaped card 32. The fan-shaped card 32 penetrates between two adjacent clamping blocks 12 and abuts against the convex strip 232, and the L-shaped clamping strip 31 penetrates into the gap between the convex strip 232 and the mounting groove 11.

[0035] The cam 232 is then inserted into the mounting groove 11 by inserting the L-shaped card strip 31 into the gap between the mounting groove 11 and the cam 232 until the cross plate at the top of the L-shaped card strip 31 abuts against the fan-shaped card strip 32. The L-shaped card strip 31 completely engages the cam 232 in the mounting groove 11 and limits the fan-shaped card strip 32.

[0036] Specifically, the crushing blade 2 is set to a single-piece structure, which makes it easy for staff to disassemble and replace damaged individual blades without replacing the entire blade, which not only saves production costs but also reduces resource loss; the crushing blades 2 and the crushing blade 2 and the rotating shaft are all loosely connected within a certain range, because the crushing blade 2 easily generates a lot of heat during high-intensity rotation, and it is easy to destroy the operating stability of the crushing blade 2 and the rotating shaft 1 during high-speed rotation to crush wood waste. The relatively loose single-piece crushing blade 2 can absorb and buffer the impact to a certain extent, thereby maintaining the overall stable operation. A certain range of movable gaps are left between the convex strip 232, the L-shaped card strip 31, the fan-shaped card 32 and the card block 12, which can cope with the expansion of components caused by heat generated under high-speed rotation, thereby improving the safety and stability of the device operation.

[0037] In this embodiment, the top surface of the protrusion 232 is on the same horizontal plane as the top surface of the rotating shaft 1, the bottom surface and top surface of the fan-shaped card 32 are respectively abutted against the protrusion 232 and the block 12, and the top surface of the block 12 is on the same horizontal plane as the top surface of the L-shaped card strip 31; the diversion assembly 4 includes an annular diverter plate 41 and a diverter cone 42, and the bottom of the annular diverter plate 41 is provided with a limiting groove 411, and the block 12 and the top of the L-shaped card strip 31 are inserted into the limiting groove 411 and abutted against the top surface of the limiting groove 411.

[0038] In this embodiment, an inner ring bolt hole 412 and an outer ring bolt hole 413 are provided on the top surface of the annular diverter plate 41, and a bolt hole corresponding to the inner ring bolt hole 412 is also opened on the top surface of the rotating shaft 1. The annular diverter plate 41 is fixed to the rotating shaft 1 by a first bolt 414. A diverter cone 42 is provided on the annular diverter plate 41, and a bolt hole corresponding to the outer ring bolt hole 413 is provided on the inclined surface of the diverter cone 42. The diverter cone 42 is connected to the annular diverter plate 41 by a second bolt 421.

[0039] Specifically, first install the annular diverter plate 41, insert the first bolt 414 into the inner ring bolt hole 412, and install the annular diverter plate 41 on the rotating shaft 1. At this time, the top of the block 12 and the L-shaped clamping strip 31 are against the limiting groove 411, limiting the block 12. At this point, the crushing blade 2 is completely fixed in the rotating shaft 1; then insert the second bolt 421 into the outer ring bolt hole 413, and install the diverter cone 42 on the annular diverter plate 41. The diverter cone 42 is set so that the input wood waste can be evenly scattered onto each crushing blade 2, thereby improving the uniformity of crushing and improving the crushing efficiency to a certain extent.

[0040] In this embodiment, the bottom of the rotating shaft 1 is connected to the output end of the rotating motor, the crushing blade 2 does not contact the inner circumference of the crushing barrel 5, and a bolt plate 51 is provided at the bottom of the crushing barrel 5.

[0041] Specifically, the crushing barrel 5 is mounted on the corresponding crushing device through a bolt plate 51 .

[0042] Working principle: Start the rotating motor, which drives the pulverizing blades 2 to rotate at high speed through the rotating shaft 1, and put the wood waste into the crushing barrel 5. The wood is dispersed to each pulverizing blade 2 through the diverter cone 42. The wood is quickly cut by the first blade 21. During the falling process, it is hit by the high-intensity impact of the pulverizing blade 2. It is then crushed into fine powder by the tip of the triangular cutter 22 and the second blade 221. The highly crushed wood is carried by the downward airflow into the discharge port below the pulverizing blade 2. The degree of pulverization of the wood waste can be changed by adjusting the speed of the rotating motor.
