The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
A kind of wood chipper rotor, as shown in Figs. 1-5, including mandrel 1 and pulverization roller 2, the pulverization roller 2 are fixed on institute
It states on mandrel 1.The mandrel 1 is rotatably dispose in the crushing bin of wood chipper by rolling bearing units, described in the pulverization roller 2
Including 4 group pulverizing units, the pulverizing unit is circumferentially set to the outer of the mandrel 1 using the center line of the mandrel 1 as axis
Side, and it is in turn connected to form an entirety, pulverizing unit described in every group includes support plate 21, fly cutter seat 23 and bending plate 22, institute
It states fly cutter seat 23 and connects the support plate 21 and bending plate 22.The material of the bending plate 22 be steel plate, the bending plate 22 to
Inner bending forms a groove (not shown).
Fly cutter 3 is installed, the fly cutter 3 extends along the length direction of the pulverization roller 2, described to fly on the fly cutter seat 23
The length of knife 3 is less than the length of the bending plate 22 and is greater than or equal to the half of the length of the bending plate 22, adjacent described
One of fly cutter 3 in fly cutter 3 on pulverizing unit is located at the side of the pulverization roller 2, another fly cutter 3 is located at the powder
The other side of broken roller 2.
The length of fly cutter 3 is less than the length of the fly cutter of traditional rotor, and therefore, the length of fly cutter stress reduces, it is easier to by
Power is uniform, is not easy to damage because of unbalance stress two, and service life is longer, reduces vulnerable part cost, although the length of fly cutter 3 is smaller,
But the area of cut of entire rotor is not less than traditional rotor.And since fly cutter is shorter, the cheap and weight of fly cutter
It is relatively light.
Straight line and 3 place of fly cutter where the diameter of the mandrel 1 in straight line, by the center of the fly cutter 3
Plane is perpendicular, and the cutting edge of the fly cutter 3 is located at the outside of the pulverization roller 2.Cutting when fly cutter 3 can be allowed to contact timber
Sword timber vertical as far as possible, improves the force-bearing situation of cutting edge, the opposite abrasion for reducing fly cutter 3, while falling after cutting
Material is fallen in as far as possible in charging conduit 26.
The both ends of the pulverization roller 2 are respectively fixed with end plate 24, and the center of the end plate 24 offers through-hole, the through-hole
Interior to be equipped with tensioner connector sleeve 11 (model ZT3-75X115), the end plate 24 passes through the tensioner connector sleeve with the mandrel 1
11 are fixedly connected, and are pulverization roller cavity 28 inside the pulverization roller 2.
Partition 25 is equipped in the groove, the groove is divided into charging conduit 26 and seal groove 27 by the partition 25, described

The side wall of 22 inside of bent plate is equipped with the second stiffening plate 272.The partition 25, first stiffening plate 271 and described second add
Strong plate 272 strengthens the structural strength of the bending plate 22, so that the intensity of entire rotor is reinforced.The partition 25, described
One stiffening plate 271, the end plate 24 and the bending plate 22 form a closed space, so set, make rotor lighter,
Higher integral strength simultaneously.
The charging conduit 26 side adjacent with the end plate 24 extends outwardly, and perforation end is formed on the end plate 24
The opening 241 of plate 24.The high speed rotation for crushing rod 2 gives the material after cutting with sufficiently large centrifugal force, each
The crushing bin of wood chipper is smoothly thrown away when charging conduit 26 rotates to discharging channel side because of no barrier, realizes quickly row
Material.
According to the design experiences of the wood chipper of many years, the outer diameter of the pulverization roller 2 is 508mm, and revolving speed is
2100RPM, the log of the 2 machinable diameter 300mm of pulverization roller.Make the dynamic balancing of rotor by the dynamic balancing measurement of profession
Accuracy class is not less than G6.3, thus rotor may be implemented and steadily run at high speed that (traditional drum chipper cutting rotational speeds are general
Lower than 1000RPM), as rotor runs at high speed in the unit time, the frequency for cutting timber is also correspondinglyd increase, in charging rate
Single cutting output significantly reduces in the case where certain, thus cutting power greatly reduces.
The quantity of the pulverizing unit is equal to the quantity of the fly cutter 3, the quantity of the fly cutter 3 according to the size of fly cutter 3,
The rotary inertia of pulverization roller 2, powder particle diameter are simultaneously chosen to be 4 in conjunction with many years design experiences, 4 fly cutter on the surface of pulverization roller 2
Layout "Z"-shaped, and axial is in 90 ° of distributions, it is 90 ° of every turn of rotor, primary with regard to staggered cutting, it had both solved because material is more, flies
The problem of knife 3 is relatively chopped less than material, while reducing every cutting power knife.
Diesel engine (not shown) is installed, the end plate 24 far from the diesel exhaust gases mouthful on wood chipper
Surface be equipped with 4 groups of blades 4 at equal intervals close to edge is circumferential, blade 4 described in every group includes the first trapezoidal blade of section
41 and section the second blade 42 triangular in shape.Radial distribution of first blade 41 along end plate 24, second blade 42
It is perpendicular with first blade 41, and it is fixed to side of first blade 41 far from the charging conduit 26.With crushing
Roller 2 runs at high speed, and constantly the air blast outside crushing bin enters air pressure in crushing bin increase crushing bin to blade 4, accelerates discharge, protects
Having demonstrate,proved the material that each fly cutter 3 is cut can be discharged quickly, to improve equipment operation efficiency.
The fly cutter seat 23 includes threaded block 231 and tool apron 232, and the length of the tool apron 232 is equal to the bending plate 22
Length, the length of the threaded block 231 is equal to the length of the charging conduit 26.The tool apron 232 is welded in the pulverization roller 2
On the end plate 24 at both ends, the threaded block 231 is placed in the charging conduit 26.Threaded block can take out from the opening of end plate
Perhaps be put into when the screw thread in some threaded hole on threaded block due to torsion is larger or be used for a long time damage, can not be complete
When tightening, quickly replacement threaded block can be convenient, and be unlikely to entire rotor and all scrap.
Through-hole is offered on the fly cutter 3, tool apron 232, is opened up at the position of through-hole described in 231 face of threaded block
There is threaded hole, fastening bolt 233 is equipped in the through-hole, the tail portion of the fastening bolt 233 passes through through-hole and is screwed into the screw thread
In hole, the fly cutter 3 is installed on the threaded block 231 by the fastening bolt 233.The fastening bolt 233 is height
Strong fastening bolt 233, strength grade reach 12.9 grades.
The wood chipper is equipped with diesel engine (not shown), one end of the mandrel 1 by belt pulley with it is described
The output shaft of diesel engine is connected, and the diesel engine is the power source of the mandrel 1 rotation.
The course of work of the invention are as follows:
Wood chipper rotor of the present invention is mounted on mobile wood chipper.When work, pass through diesel engine band
Dynamic belt pulley realizes running at high speed for rotor, when raw material is sent by feeding mechanism, i.e., cuts into wood chip by fly cutter 3, works as blanking
