Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for manufacturing sawdust. Conventionally, when manufacturing sawdust, a multi-circular saw, a rotary hammer, etc. was used alone inside a safety cover. The machine is pivoted on the machine, and the board pieces generated in sawmills and wood factories are carried into the safety cover and cut into sawdust.

Problems to be Solved by the Invention However, the above-mentioned sawdust manufacturing machine has a drawback in that coarse particles tend to be mixed into the sawdust.

In order to solve the above-mentioned drawbacks, the present invention has a multi-circular saw pivoted at the upper position inside the safety case, and a rotary hammer at the lower position, which is rotated in conjunction with the rotary hammer and sucked into the upper and lower sides of the safety case. This is a device that connects ducts and sucks up the scraps crushed by the multiple circular saws at the top, while the coarse scraps are completely pulverized by the hammer at the bottom and then sucked out.It is designed to improve the accuracy of sawdust. 0 Means for Solving the Problems Below, the present invention will be explained in detail with reference to embodiment drawings.0 A lower cover box 2 is erected on the upper surface of the base frame 1, and a lower cover box 2 is installed at the upper end of the lower cover box 2. An upper cover box 3 with an arcuate surface extending from the upper surface to both sides is erected and communicated with the upper and lower sides, a bearing frame 4 is connected to the rear of the lower cover box 2, and bearings 5, 5' are mounted on the upper surface of the bearing frame 4. and tighten the bearing 5.
, 5', and the tip thereof passes through the upper cover box 3 at a position on the right side of the center. The multi-stage inclined saw 10, which has both ends secured with seats 9 and 9', is secured by inserting a large number of the upper cover box 3 alternately.
The tip of the first rotary shaft 6 is pivotally supported by a bearing 11 provided on the front side of the box, and a wood entrance 12 is opened on the right side of the upper cover box 3, facing the center position of the front and rear surfaces of the lower cover box 2. A bearing 13.13' is installed, the second rotating shaft 14 is supported by the bearing 13.13' through the inside of the lower cover box 3, and the radially symmetrical positions of the opposing flange plates are connected by a large number of shafts 15. A rotary hammer 18, which has a disk 16 inserted into each shaft 15 and the lower end of the hammer 17 loosely attached to the shaft 15 in the gap between each disk 16, is fixed to the second rotating shaft 14, and the second The rotating shaft 14 and the first rotating shaft 6 are interlocked by an interlocking mechanism 19 such as a belt pulley, and a suction port 20 is opened at the upper position of the left side of the lower cover box 2, and a wire mesh 21 is stretched over the lower cover box 2. Square tube chute 22 on the bottom of box 2
A suction duct 24 extending from a suction device 23 is formed into two prongs to form a sawdust manufacturing machine 25 that communicates with the suction port 20 and the lower end of the square tube chute 22. In the figure, reference numeral 26 indicates a wood carrying conveyor, and reference numeral 27 indicates a viewing window. Functions and Effects In the sawdust manufacturing machine 25 of the present invention, the first rotating shaft 6 is rotated by an external prime mover while the second rotating shaft 14 is interlocked. and rotate the multi-stage inclined saw 10 and rotary hammer 18 in the upper and lower cover boxes 3.2 as shown by the arrows in FIG.
The suction device 23 is driven to apply suction negative pressure to the suction duct 24. A carry-in conveyor 26 is installed facing the lumber carry-in port 12 of the upper cover box 3.
The tip of the wood brought into the machine through the wood delivery port 12 comes into contact with the multi-stage inclined saw 10 and is not cut, but becomes sawdust and is passed through the wire mesh 21 of the suction port 20 on the other side.
The air is sucked into the upper suction duct 24 through the suction duct 24. The scraps cut by the multi-stage inclined saw 10 fall downward and rotate at the lower position.
8(7) The particles are beaten and crushed by each hammer 17 into fine particles, which fall into the suction duct 24 from the square tube chute 22 and are also sucked into the suction machine 23. Therefore, the present invention In the sawdust making machine 25, the sawdust is completely refined and uniform sawdust can be manufactured, and since the multi-stage inclined saw 10 and the rotary hammer 18 are vertically opposed, the machine body can be made compact and compact. The saw blades can be operated in conjunction with a single prime mover, and produce the remarkable effects described above, such as being able to efficiently produce sawdust.
