A transmission link 25 is hinged on the front edge of the runner 23, the lower end of the transmission link 25 is hinged on the runner 23, the upper end of the transmission link 25 is hinged on the sliding sleeve 4, and the lower end of the sliding sleeve 4 is fixed vertically A leg 17 is installed. The lower end of the leg 17 is rotatably provided with a limit roller 18 that abuts on the bottom surface of the swing plate 24; the guide rod 5 is movably sleeved with a return spring 26, and the left end of the return spring 26 is fixed on the left side. On the right side wall of the plate 2, the right end of the return spring 26 is fixed on the left end of the sliding sleeve 4. The right side wall of the right vertical plate 14 is fixedly installed with a sawdust collecting trough 9, and the right side wall of the sawdust collecting trough 9 is provided with a conveying hole 10. The right end of the swing plate 24 is obliquely fixedly installed with a net plate 8 opposite to the conveying hole 10, a baffle 7 is vertically fixed at the connection between the swing plate 24 and the net plate 8, and the right end of the horizontal plate 29 is suspended The sleeve 6 above the screen 8; the bottom plate 1 is fixedly installed with a storage tank 11, and the sawdust collection tank 9 is located inside the storage tank 11; a limit spring 28 is connected between the compression rod 12 and the bottom plate 1 to limit the position The lower end of the spring 28 is fixedly installed on the upper surface of the bottom plate 1, and the upper end of the limit spring 28 is fixed on the lower bottom surface of the compression rod 12.
[0020] The working principle and use method of the present invention are:
[0021] When in use, the log is passed through the sleeve 6, the driving device drives the driving pulley 21 to rotate, the driving pulley 21 drives the driven pulley 19 to rotate through the flat belt 22, and the driven pulley 19 drives the runner 23 to rotate. The rotation of 23 drives the sliding sleeve 4 to reciprocate left and right along the guide rod 5 through the transmission link 25; during this period, the rotating motor 27 is started to drive the cutting blade 3 to rotate, and the sliding sleeve 4 drives the rotating motor 27 to reciprocate left and right. When 27 drives the cutting blade 3 to move to the right, the cutting blade 3 cuts the log on the sleeve 6 to the right. The cut log falls on the screen 8, and the sliding sleeve 4 drives the leg 17 to reciprocate and support The leg 17 is pressed against the swing plate 24 by the limit roller 18 to slightly alternately swing clockwise and counterclockwise under the elastic force of the vibration spring 16, thereby driving the screen 8 to slightly alternate clockwise and counterclockwise. When the screen 8 swings clockwise to a certain angle When the right end of the mesh plate 8 is lower than the lower edge of the conveying hole 10, the log section on the mesh plate 8 passes through the conveying hole 10 and enters the storage tank 11 to be collected. At the same time, the swing of the mesh plate 8 promotes the cutting process The sawdust generated in the process can quickly pass through the screen 8 and enter the sawdust collecting trough 9 to be collected; starting the telescopic cylinder 13 can drive the support platform 15 together with the runner 23 to adjust the height of the upper and lower positions. When the height of the runner 23 decreases, The lateral sliding stroke of the sliding sleeve 4 is shortened. At this time, the cutting feed depth of the cutting blade 3 is reduced, which is suitable for cutting logs with a smaller diameter. When the height of the runner 23 increases, the lateral sliding stroke of the sliding sleeve 4 increases At this time, the cutting feed depth of the cutting blade 3 increases, which is suitable for cutting larger diameter logs; the compression rod 12 drives the tension wheel 20 to compress the flat belt 22 under the elastic force of the limit spring 28 to achieve The tensioning effect of the flat belt 22 avoids the slack phenomenon of the flat belt 22 when the height of the runner 23 is adjusted.
[0022] In the present invention, the support platform 15 is driven by the telescopic cylinder 13 to adjust the height of the upper and lower sides, so as to realize the adjustment of the length of the left and right strokes of the sliding sleeve 4 along the guide rod 5, which is convenient for cutting logs of different sizes, and is pressed flat by the tension wheel 20 The belt 22 ensures that there is sufficient transmission friction between the driven pulley 19, the driving pulley 21 and the flat belt 22, which increases the smoothness of the transmission, thereby improving the cutting effect of the log; the screen 8 can be forward and backward The hour hand rotates slightly alternately. On the one hand, it is convenient for the sawdust generated during the cutting process to fall into the sawdust collecting groove 9 to be collected. On the other hand, the logs cut into sections can pass through the conveying hole 10 and enter the storage groove 11 to realize the sawdust and roundness. The separation of wood improves the cleanliness of logs after cutting to a certain extent.
