The above-mentioned pencil-knife that digs core that easily changes, described projection are connected with draw-in groove, comprise being located at the projection of digging on the core end face, are located at the draw-in groove that adapts with described projection on load transfer device or the main frame; Described projection is connected also with draw-in groove, comprises being located at the draw-in groove that digs on the core end face, is located at the projection that adapts with described draw-in groove on load transfer device or the main frame.
Arbitrary above-mentioned pencil-knife that digs core that easily changes, described load transfer device are manual rocking bar or the gear mechanism that is connected with motor.
Compared with prior art, the utility model easily changes the pencil-knife that digs core, is convenient to dismounting nested connection of ground with main frame and load transfer device respectively owing to digging core, when digging the core damage, take off the plane core of damage from main frame easily, also easily good plane core is installed on the main frame.
Description of drawings
Fig. 1 is that the utility model easily changes the pencil-knife structural representation that digs core;
Fig. 2 digs the nested syndeton schematic diagram of core among Fig. 1;
Fig. 3 is the structural representation that digs core among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of pencil-knife that digs core that easily changes, comprise main frame 101, be located at the plane core 102 on the main frame 101, the load transfer device 103 that is connected with plane core 102, as shown in Figure 3, dig core 102 and comprise core frame 104 and the blade 105 that is located on the core frame 104, dig core 102 and be convenient to dismounting nested connection of ground with main frame 101 and load transfer device 103 respectively; Above-mentioned load transfer device 103 is the gear mechanism that is connected with motor, the above-mentioned nested axle that is connected to is connected with axle sleeve, axle is connected with axle sleeve and comprises: be located at the connecting axle 106 on plane core 102 end faces, be located at the axle sleeve 107 that adapts with connecting axle 106 on the gear 109 of described gear mechanism and the main frame 101; The axle sleeve degree of depth on the main frame 101 is 1.2 times of the length sum of digging core 102 two ends connecting axles 106; On the axle sleeve of main frame 101, be provided with slide damper 108.
Take off when digging core 102, baffle plate 108 is pushed open, make and dig core 102 and fall in the axle sleeve on the main frame 101, make and dig core and gear mechanism disengagement, so just can easily take off the plane core, otherwise, when changing new plane core, put in the axle sleeve on the main frame 101 digging core one end, the other end that will dig core then is inserted in the axle sleeve of gear mechanism, the baffle plate that closes at last so just can be installed the plane core easily.Because the setting of baffle arrangement can make plane core and gear mechanism in conjunction with closely, prevents slippage when the planing pencil.
