Referring to Fig. 1 to Fig. 3, actuating unit 400 is arranged on vehicle frame 100.Actuating unit 400 includes electromotor 410, storage battery 420 and starter motor 430, and the output shaft of electromotor 410 is provided with output shaft rotation wheel 440 and electromagnetic clutch 450.Electromotor 410 is arranged on vehicle frame 100 by engine foundation (figure is not marked), plays to the effect of electromotor 410 damping.Storage battery 420 is for powering for starter motor 430 and electromagnetic clutch 450, and electromagnetic clutch 450 rotates wheel 240 by conveyer belt 460 with cutting axis and is connected.The energising situation of electromagnetic clutch 450 controls cutting axis and rotates the rotation situation of wheel 240.Output shaft rotation wheel 440 can be output shaft belt wheel, utilizes the characteristic of V belt translation, it is allowed to transship and skid.
When electromagnetic clutch 450 is energized, the power of electromotor 410 is transferred to electromagnetic clutch 450 by its output shaft, electromagnetic clutch 450 is transferred to cutting axis by conveyer belt again and rotates wheel 240, cutting axis rotates wheel 240 drive cutting axis 210 and rotates and then drive Cutting tool 220 and cutting tooth 230 thereon to rotate, to cut stub.The power of electromotor 410 output is transferred to Cutting tool 220 by the way of band transmits, wherein without slowing down.When electromagnetic clutch 450 power-off, the power of electromotor 410 cannot be transferred to cutting axis by electromagnetic clutch 450 and rotate on wheel 240, and therefore Cutting tool 220 and cutting tooth 230 thereon do not rotate.
Seeing also Fig. 7, controlling organization 500 is arranged at the rear end of vehicle frame 100.Controlling organization 500 includes that control handle 510, shelves are 520, brake 530, engine throttle 540 and air door 550, control handle 510 turns to for control, shelves are used for controlling advance or the retrogressing of walking mechanism 300 520, brake 530 is for controlling the parking of walking mechanism 300, and engine throttle 540 and air door 550 are for controlling the operation of electromotor 410.Control handle 510 includes support 511 and the operation handle 512 being arranged on support 511, support 511 is arranged on vehicle frame 100, and support 511 is arranged at an angle with vehicle frame 100, the position of Cutting tool 220 and operation handle 512, at the two ends of vehicle frame 100, operates safety.
Hydraulic pump 320 is connected with output shaft rotation wheel 440, and by shelves, 520 control hydraulic pumps 320 is reached to control advance and the retrogressing of wheel 340, and brake 530 reaches the purpose of parking by limiting the motion of differential mechanism 310.Electromotor 410 is connected by V belt translation with the hydraulic pump 320 of walking mechanism 300, provides power drive wheel 340 to rotate for hydraulic pump 320 and realizes automatic walking function.Hydraulic pump 320 1 aspect realizes the function slowed down, and on the one hand also provides powerful moment of torsion for wheel 340, makes the highest abrupt slope that can climb 30 degree of vertical plate formula stump cleaning machine 10.Hydraulic pump 320 and differential mechanism 310 are designed as the structure of one simultaneously, and the width of stump cleaning machine is reduced so that stump cleaning machine can facilitate stump puller in the operation in forest zone through slype wide for the narrowest 800mm.
The power of above-mentioned vertical plate formula stump cleaning machine 10 is provided by electromotor 410, communicated band is respectively Cutting tool 220 and provides power with hydraulic pump 320, principal cutting movement is Cutting tool 220 and the high speed rotating of cutting tooth 230, feed motion is controlled translation and the lifting of Cutting tool 220 by control handle 510, realize the cutting of stub and surrounding soil, passed to the power of hydraulic pump 320 and differential mechanism 310 by electromotor 410 simultaneously and realize the automatic walking function of vertical plate formula stump cleaning machine 10.
Particularly as follows: start starter motor 430, starter motor 430 drives electromotor 410 to work, controlled vertical plate formula stump cleaning machine 10 by control handle 510 and shelves 520 and reach site clearing, electromotor 410 provides power by conveyer belt for cutting axis 210, the energising situation of electromagnetic clutch 450 decides whether to drive cutting axis 210 to rotate, Cutting tool 220 is driven to rotate when cutting axis 210 rotates, and then drive cutting tooth 230 thereon to rotate, with wheel 340 as fulcrum, the control handle 510 that swings makes vehicle frame 100 swing, drive the Cutting tool 220 being connected with vehicle frame 100 to swing milling stub with this, then control handle 510 is up moved and make Cutting tool 220 move down deep cutting stub the soil machining away around stub.Machinery is well combined by this excavating stump device with manual operation, principal cutting movement is completed by mechanical part, feed motion is by manual operation control, frame for movement is made to simplify as far as possible, mechanical dimension than realizing the cleaning dozer of function of the same race, tooth pushing machine is much smaller, power is also much smaller than these big machineries (18kw) and little to the destruction on ground, it is to avoid soil erosion.
Owing to the mode of milling needs to cut back and forth, it is impossible to disposably remove stump so that work efficiency is the most much smaller with big machinery.This vertical plate formula stump cleaning machine 10 is cutting with roots and soil, stay next heatable adobe sleeping platform the deepest for 500mm on ground after having cut, hack has all stayed ground with wood fragments bits, completes the process digged pit, loosen the soil for follow-up plantation, and the wood flour stayed can also play the effect of fertilizer.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
