Because automatic mower belongs to existing mature equipment,Below the improvement part structure only the utility model being related to is described, and other structures are notRepeat again.
In conjunction with shown in Fig. 3 to Fig. 5, the automatic mower specific works mistake that the utility model providesJourney is such: in the process of automatically mowing at automatic mower, when user need to be according to grassWhen the height on level ground regulates the height of cutterhead system 500, rotation knob 100, due to knob 100Interfix with urceolus 200, such as: knob 100 can use card with urceolus 200Button is rigidly connected, and knob 100 drives urceolus 200 to rotate together, and now, inner core 300 canIn the interior upper and lower displacement of body 1000, but can not rotate with respect to body 1000, and outerCylinder 200 can rotate, but can not be with respect to body 1000 upper and lower displacements, and urceolus 200 and inBetween core 300, be mutually screwed together by internal thread 210 and external screw thread 310, therefore,In the time that urceolus 200 is clockwise or be rotated counterclockwise, inner core 300 upper and lower displacement thereupon,Because inner core 300 and motor 400 and cutterhead system 500 are rigidly connected, thus band movable knife disc systemSystem 500 is with respect to the upper and lower displacement of body 1000.
Rotate along with knob 100 drives inner core 300, external screw thread 310 rotates thereupon, shell fragment 600Progressively snap in each groove 330, be used for controlling different gears. The setting party of groove 330Between formula and gear, there is corresponding relation, such as: in quantity, the quantity setting of grooveMust be more, gear interval is just divided carefullyyer; Different gear corresponding to groove. Shell fragment600 insert groove 330 is more deeply more not easy slide piece, and shift feeling is stronger. In addition, due to shell fragment600 adopt Compress Spring conventionally, and itself has pressure to the outer wall of inner core 300. Work as needsWhen shell fragment discharges, rotary inner core 300, because groove 330 itself is arc, rotationTime, shell fragment 600 overcomes spring pressure can depart from this groove.
Be disposed radially in limited block 220 and the correspondence of urceolus 200 outer walls and be arranged on positioning tableUnder the effect of the protrusion stop bit 1201 on 1200, in the process of rotation knob 100, by cutterheadSystem 500 is limited to the highest or extreme lower position. Specifically, current location as shown in Figure 3,Limited block 220 and protrude stop bit 1201 a relative side mutually against, suppose now cutterhead system500 in extreme higher position, when knob 100 is clockwise or after being rotated counterclockwise less than one week, and limitPosition piece 220 and the opposite side that protrudes stop bit 1201 mutually against time, 500 of cutterhead systems inExtreme lower position. That is to say, the utility model is by limited block 220 and protrudes stop bit 1201Relative position to change to realize the height of cutterhead system 500 spacing. Due to extreme higher position andThe difference in height of lower position is to be decided by the pitch size of internal and external screw thread, is ensureing certain spiral shellUnder the prerequisite of distance, can ensure between extreme higher position and extreme lower position, to there is enough differences in height.Such as: in the present embodiment, the design parameter of pitch is 40mm, therefore, adjustable heightAlso be 40mm left and right.
In sum, the utility model is by having increased groove and elastic piece structure, and gear is fixing canLean on, the possibility and the shift feeling that greatly reduce slide piece strengthen; Meanwhile, adopt rotation radially spacing,Position limiting structure is completely enclosed within internal body, can not contact with external environment condition, simple in structure and limitPosition is reliable.
