Specific embodiment

The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model, It states.The preferred embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms in fact It is existing, however it is not limited to embodiment described herein.On the contrary, purpose of providing these embodiments is makes public affairs to the utility model It is more thorough and comprehensive to open content.

It should be noted that when element be considered as " setting " or " connection " on the other element, it can be directly Setting connects on the other element or may be simultaneously present centering elements.

Unless otherwise defined, the technical field of all technical and scientific term and the utility model used herein The normally understood meaning of technical staff it is identical.Term used in the description is intended merely to describe specifically to implement purpose, It is not intended to limit the utility model.

As shown in Figure 1, 2, 3, the heavy type multiple blade saw including body 1, is set to running part and the setting of internal body In the sawing part of internal body, in which: the sawing part includes cutter shaft 2 and is distributed in cutter shaft table by the connection of spring 3 Several saw blades 4 in face, cutter shaft 2 are the hollow shaft of inner hollow closed at one end, and the cutter shaft of inner hollow is used to be passed through cold wind, Several screw holes 5 are distributed on axle body, the Extendible flake 6 with spring one is connected on spring 3, is opened on Extendible flake with both ends of the spring Have with the consistent through-hole 7 of 5 size shape of screw hole, spring can be neatly according to the specification size of timber to the spacing between saw blade It is adjusted, recycles screw by the screw hole on the through-hole and cutter shaft axle body on spring when adjusting the suitable spacing needed to operating condition It tightens and is fixed up；Cutter shaft axle body is equipped with several several ventilation slots 8 through axial wall, and ventilation slot is used to dissipate in cutter shaft The cold wind being passed through effectively can carry out wind cooling temperature lowering to the saw blade during sawing, avoid as traditional water-cooled cooling side Formula bring environment is slovenly, is difficult to the drawbacks of clearing up；Lower part is equipped with dust exhaust apparatus 9 in the body 1, can form negative pressure ring Border carries out effective absorptive collection to the wood powder generated during sawing.

As shown in Figure 2,3, the ventilation slot 8 is the string configuration for being slightly less than 2 axial length of cutter shaft, guarantees axle body length side Effective temperature-reducing can be obtained to each saw blade of distribution；Ventilation slot is equidistantly evenly distributed on 2 axle body of cutter shaft and quantity It is at least three, guarantees that each position of each saw blade can be blown to by cold wind.

As shown in Fig. 2, the cutter shaft 2 includes the closed end 2-1 and and air-cooler being connected with driving equipment (figure not depending on) (figure does not regard) connected ventilation end 2-2, air-cooler generates cold wind and is delivered to inside cutter shaft, and pressure liter in axis is caused in closed end Height keeps cooling effect more preferable so that the cold wind being passed through be made to exhale with more powerful power.

As shown in Fig. 2, the spring 3 is the mild steel piece of thinner thickness, it can preferably be attached at the axle body outer wall of cutter shaft 2 On.

As shown in figure 3, the saw blade 4 is connected on spring 3, spring is fitted and connected on 2 surface of cutter shaft, cutter shaft surface Be additionally provided with blade strengthening mechanism 10 other than springs, saw blade rely solely on spring and be connected on cutter shaft be it is far from being enough, therefore Blade strengthening mechanism can reinforce the stability that saw blade is connect with cutter shaft axle body.

As shown in Figure 1, the running part includes pressure roller 11 and the lower compression roller being correspondingly arranged immediately below it in several groups 12, running part is in the left and right two sides for being symmetrically distributed in sawing part, to guarantee the steady transmission of wood workpiece.

As shown in figure 4, the upper pressure roller 11 is connected by loop bar 13 with 1 roof of body, loop bar 13 includes upper hollow Bar 13-1 is fixedly connected on the fixed station 15 of lower part in body with the lower beam 13-2 being connected therewith by reset spring 14, lower compression roller On, reset spring realizes that the distance between upper and lower pressure roller can flexibly change, and lead to timber of different specifications and sizes can smoothly It crosses.

As shown in Figure 1, the body 1 is equipped with feed inlet 16 and discharge port 17, facilitate the charging and discharging of timber；Charging Mouth end is equipped with the push workbench 18 being connected with body, smoothly to push timber inside body 1.

Embodiment described in the utility model is only the description carried out to preferred embodiments of the present invention, not The utility model conception and scope is defined, under the premise of not departing from the design concept of the utility model, work in this field The all variations and modifications that journey technical staff makes the technical solution of the utility model should all fall into the protection of the utility model Range, technical content requested for protection of the utility model are all described in the claims.
