Detailed description of the invention

nullAs Fig. 1 is to shown in 9: log splitter，Including frame 1，Frame 1 therein is made a square framework by angle steel welding，Roller 10 can be installed in the lower section of framework，Upper end in framework is interval with two the first axle beds 32，First axle bed 32 is connected with framework by screw，And the dead in line of two the first axle beds 32，Rotating shaft 3 is arranged in the first axle bed 32，First driven pulley 31 is installed at the middle part of rotating shaft 3，And one end of rotating shaft 3 extends to outside frame 1，It is installed with motor 2 in the lower end of frame 1，The output shaft of motor 2 is provided with the first drive pulley 21，First driven pulley 31 and the second drive pulley 21 connect and has a belt 23，42 one end extended to outside frame 1 of clutch shaft bearing are provided with sawmilling assembly 4，Under the driving of motor 2，Rotating shaft 3 can rotate in clutch shaft bearing 42，Rotating shaft 3 drives sawmilling assembly 4 to move；

Sawmilling assembly 4: include the ball bearing 42 that inner ring is enclosed within rotating shaft 3, the bracer 41 being connected on ball bearing 42 outer ring, the chain saw being arranged in rotating shaft 3 and be arranged on the handle 6 of chain saw one end；Described chain saw includes the sprocket wheel 43 being arranged in rotating shaft 3, one end carrier bar 44 affixed with bracer 41 and is arranged on saw chain on sprocket wheel 43 and carrier bar 44；Handle 6 is arranged on carrier bar 44 one end away from sprocket wheel 43.

Further, a cavity 61 is offered in handle 6, one end of chain saw and carrier bar 44 is positioned at cavity 61, many positioning sleeves 62 it are mounted with in the both sides cavity 61 of carrier bar 44, in each positioning sleeve 62 is with the axis of carrier bar 44 for the cavity 61 of the symmetrical both sides being placed in carrier bar 44 of line of symmetry, carrier bar 44 and cavity 61 outer wall offer multiple through hole corresponding with positioning sleeve 62, securing member 63 is installed in through hole, at handle 6, one portion of the handle can also be set away from vestibule one end, the chain saw of rotation can be separated by positioning sleeve 62 with cavity 61, prevent the chain saw rotated from touching cavity 61 inwall, portion of the handle facilitates operator handle 6.

After motor 2 rotates, the first drive pulley 21 is driven to rotate, torsion is passed to the first driven pulley 31 by belt and rotates by the first drive pulley 21, first driven pulley 31 takes rotating shaft 3 to after rotating and rotates in clutch shaft bearing 42, rotating shaft 3 rotates and sprocket wheel 43 is rotated, sprocket wheel 43 drives saw chain to rotate, the chain saw rotated is utilized to can be used to cut timber 9, when needs cutting timber 9, the portion of the handle of handle 6 can be held, press downwards, because carrier bar 44 is affixed with a bracer 41, therefore carrier bar 44 can move down with rotating shaft 3 for axle center under the support of bearing 42 with saw chain, after moving down, just timber 9 can be cut.

Further, frame 1 is additionally provided with one for timber 9 hold down gag compressed by timber 9, the effect of hold down gag is to be possible to prevent timber 9 left and right during cutting to roll, and it includes the depressed portion 5 being arranged on frame 1 upper end and is arranged on the holding portion 7 in the middle part of frame 1；

Depressed portion 5 includes the rotary sleeve 51 being fixed in frame 1 upper end, one rotating support shaft 52 is installed in rotary sleeve 51, also include the depression bar 55 that one end is fixed in support shaft 52, depression bar 55 is socketed with gland 54, gland 54 is connected with a pressing plate 53, pressing plate 53 offers the gully of an arc towards one end of frame 1, rotary sleeve 51 is preferably installed in frame 1 upper end with two intervals, after rotary sleeve 51 is fixed, again support shaft 52 can be inserted in two support sets, then one end of depression bar 55 is being weldingly fixed on the supporting axis between two rotary sleeves 51；

Holding portion 7 includes the gripper shoe 71 that one end is fixed in frame 1, is provided with many support bars 72 below gripper shoe 71, and one end of support bar 72 is fixing with gripper shoe 71 to be connected, and other end is affixed with frame 1.

After again timber 9 being placed in gripper shoe 71, can be with hand-held depression bar 55, press downwards, under the drive of depression bar 55, pressing plate 53 can push timber 9 to frame 1, by pressing plate 53, frame 1 and gripper shoe 71 3, timber 9 is positioned, and then timber 9 can be clamped in gripper shoe 71 firmly, and gland 54 can slide on depression bar 55, and then the timber 9 of different-diameter can be compressed, the gully of the arc on pressing plate 53 can increase the contact area between timber 9, further improves clamping effect.

Further, the cross sectional shape of depression bar 55 is polygon, and the shape of gland 54 is corresponding with the shape of depression bar 55, and this structure can rotate on depression bar 55 with gland 54 so that machine uses safer.

Further, described gripper shoe 71 offers a square hole 75, many rotary shafts it are installed with in square hole 75, each rotary shaft is all socketed with one and can roll carrying roller 74 on the rotating shaft, this structure is so that be placed on timber 9 in gripper shoe 71 and move on carrying roller 74, compare for use plane, move lighter.

Further, also include one for the stopping means limiting sawmilling assembly 4 rotational angle, described stopping means includes that one end is fixedly connected on the upper limit position block 81 on frame 1 end face and lower position block 83, a tapped through hole it is provided with in upper limit position block 81 and lower position block 83, tapped through hole at upper limit position block 81 is built-in with upper limit screw 82, tapped through hole at lower position block 83 is built-in with lower limit screw 84, when sawmilling assembly 4 is rotated up, prop up 41 1 end faces of bracer and can be resisted against one end of upper limit screw 82, when sawmilling assembly 4 rotates down, the other end propping up bracer 41 can be resisted against lower limit screw 84 one end.

Preferably, also include one for the stopping means limiting sawmilling assembly 4 rotational angle, described stopping means includes being threaded in the upper limit screw 82 on a bracer 41 and lower limit screw 84, is installed with the upper limit position block 81 corresponding with upper limit screw 82 and lower limit screw 84 and lower position block 83 in frame 1.

Stopping means can improve safety when machine uses, because when timber 9 is cut by staff handle, probably due to vibrate and cause handle to be slipped out of the hand, chain saw is caused to freely swing downwards, this situation is breakneck, it is likely to cut to human body, lower limit screw 84 and lower position block 83 in stopping means then can be after workman slip out of the hand, play an effect stopped, limit the degree of sawmilling assembly 4 swung downward, upper limit is then possible to prevent sawmilling assembly 4 to rotate from another one direction after being lifted, and then it is possible to prevent free-falling sawmilling assembly 4 to cut to human body, improve safety when device uses, wherein by regulation upper limit screw 82 and lower limit screw 84, the limited angular limiting sawmilling assembly 4 can be carried out trace adjustment.

The operational approach of the present invention: timber 9 is placed in gripper shoe 71, opening motor 2, sawmilling assembly 4 is lifted by hand-held handle, promotes timber 9 feeding suitable length, it is pressed downward against dynamic pressure bar 55, timber 9 is clamped, it is possible to the timber 9 of feeding is cut, after first paragraph timber 9 cuts, unclamp depression bar 55, again timber 9 being carried out feeding, carry out the cutting of second segment, so circulation carries out cutting section to remaining timber 9.
