Detailed description of the invention
Fig. 1 shows the schematic diagram according to chipper of the present utility model.Chipper comprises the accessories such as feed hopper 1, tapping channel 2, frame, engine 4, transmission case 5, cutting part and wheel, support portion, lift-pull handle.Described feed hopper 1 is preferably obliquely installed horizontal by an angle.Material to be comminuted is fed in feed hopper 1 and cut parts are drawn in.Described cutting part is arranged on cutting rotor, described cutting rotor in crush box with High Rotation Speed.Described crush box is the bearing of cutting rotor, feed hopper 1 and tapping channel provide support.Described engine 4 is fuel engines or motor, and it is connected by the belt in transmission case and cutting rotor thus drives cutting rotor to rotate.Material (such as band leaf or the wooden branch not with leaf and/or other organic matter) to be comminuted is cut into small pieces by described cutting part.After cutting, material chopped is discharged to outside chipper by tapping channel.
Chipper of the present utility model is provided with safety device.Described safety device comprises the safety switch for feed hopper 1 and/or tapping channel 2.Preferably, see Fig. 4, safety device comprises the safety switch 12 for feed hopper 1 and the safety switch 13 for tapping channel 2.See Fig. 5, described safety switch 13 comprises the safety switch body 14 be arranged in frame and the plug 15 be arranged on bottom tapping channel 2.See Fig. 6, safety switch 12 comprises the safety switch body 16 be arranged in frame and the plug 17 be arranged on bottom tapping channel.Described safety switch body 14,16 is provided with contact, and described plug 15,17 is arranged so that safety switch closes when described plug engages with corresponding contact, and when described plug is disengaged with corresponding contact, safety switch disconnects.Described safety device also comprises brake hard bar, and described brake hard bar is connected with at least one plug machinery, and make when user touches brake hard bar along a direction, corresponding plug moves thus can keep departing from corresponding contact.When safety switch disconnects, chipper circuit disconnects thus fail to start; When safety switch closes, chipper can start as required.
Preferably, brake hard bar is connected with plug 17 machinery bottom feed hopper 1, this brake hard bar comprises action bars 18 and drive link 19, described action bars 18 to be articulated on feed hopper 1 (see Fig. 7) and can to swing around pivot part, one end of described drive link 19 is connected on the plug 17 bottom feed hopper 1, the other end and the action bars 18 of described drive link 19 are coupled, make when applying active force to action bars 18, described drive link 19 moves thus drives described plug 17 to move to make this plug 17 keep departing from corresponding contact.
Preferably, described action bars 18 and described drive link 19 are configured to make when downward pressing operation bar 18, and described drive link 19 moves upward thus drives described plug 17 to move upward to make this plug 17 keep departing from corresponding contact.Preferably, see Fig. 8, described action bars 18 is connected by actuator 20 and described drive link 19, and described actuator is rotatably installed on a holder 21 by pivot.Described actuator is provided with lock piece, and described lock piece can make described plug latch fix on to keep with corresponding contact on the position that departs from.Described lock piece comprises the pin door bolt of band spring, the pin door bolt of described band spring can move between non-lockup state and lockup state, wherein, in described non-lockup state, the wall that the pin door bolt of described band spring can be resisted against described holder moves, in described lockup state, the pin door bolt of described band spring is locked in the pin-and-hole on the wall of holder.Pass through said structure, when user's downward pressing operation bar 18, described action bars 18 brings actuator is around pivot, described actuator and then drive drive link 19 move upward, the plug 17 be now connected with drive link 19 also moves upward, thus depart from corresponding contact, when actuator rotates to an angle thus drive link 19 and plug 17 have moved upward after certain distance, the pin door bolt of band spring moves to pin-and-hole and is locked in pin-and-hole.In this lock-out state, actuator can not be made to rotate by applying active force to action bars, therefore plug 17 departs from keeping with corresponding contact.When wanting to reset chipper, pin need be fastened with a bolt or latch with instrument and unlock from pin-and-hole, therefore improve security.
By above structure, all or part of safety switch of the present utility model has double insurance function.First, if feed hopper 1 or tapping channel do not install or loosen for a certain reason, the plug of safety switch can not engage with the contact of the body of safety switch, therefore chipper can not start, this effectively prevents feed hopper or tapping channel mounted or loosening time start the machine and the injury accident that may cause.Secondly; at least one safety switch has also been coupled brake hard bar; like this; even if feed hopper or tapping channel are reliably installed; if there is other emergencies; operating personnel also can make safety switch disconnect thus chipper is shut down by push bar simply, if while operating personnel unlock without instrument, chipper can not be activated.This double insurance substantially increases the security of chipper of the present utility model.
The tapping channel 2 of chipper of the present utility model is designed to containing bent section.The radian of described bent section is larger to avoid the material flowed out block in tapping channel 2 or flow backwards.Preferably, see Fig. 1, described tapping channel comprise be positioned at upstream vertical substantially portion's section 6, be positioned at portion's section 8 in downstream and the bent section 7 of connecting portion section 6 and portion's section 8, each portion section is designed so that material emission direction and horizontal direction angulation are in the scope of 0 ° to 20 °.The total length of described tapping channel 2 meets the requirement of safety standard for minimum safe distance.But in order to make material more early and more easily flow out and reduce the total height of tapping channel, the posterior segment of tapping channel 2 especially described in be positioned at the both sides of portion's section 8 in downstream sidewall on the otch 9 of equidistant intervals is set.As shown in Figure 2, preferably, each otch 9 in every side forms grid-like arrangement, and preferably, the height of each otch 9 in every side increases gradually from the downstream of swimming over to of effluent.Preferably, the otch 9 of both sides toward each other.In addition, more preferably, the posterior segment of tapping channel 2 especially described in be positioned at the bottom-open of portion's section 8 in downstream and there is at least one connect cross bar 10 of two side.The tapping channel of design like this can adapt to the discharge of various material well, makes material can not block, raise, under the prerequisite meeting safety standard, also make discharging more early easier simultaneously.
As shown in Figure 1, chipper comprises the bottom bay 3 of carrying complete machine weight, and described bottom bay adopts U-section, and described U-section is preferably U-shaped steel, and the U-shaped opening of described U-section toward the outer side.Described outside refers in the horizontal direction away from the side on the direction of chipper.The section bar of such layout creates unexpected technique effect, under equal conditions, its intensity adopts opening towards 4 times of the bottom bay of the U-section of disposed inboard, and this greatly reduces bottom bay 3 in use diastrophic risk, thus improves the service life of complete machine.
In addition, transmission-case cover of the present utility model is installed by Access Division 11 at least one position.Compared with the traditional approach needing a large amount of screw to carry out connecting, facilitate detachable maintaining like this and avoid connector and lose at maintenance part.
Foregoing description is the explanation of preferred embodiment and can carries out multiple amendment by those of skill in the art under the prerequisite not deviating from the scope limited by the literal of claims and equivalent scope of the present utility model.
