Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
Shown in Fig. 1 is the stepless height adjusting device of mower, and this device is mainly used in regulating mowing height of mower, makes the working environment that mowing functional adaptation is different.Mower comprises body 13, connecting rod 12, be movably connected first three gusset 8 at connecting rod 12 two ends and Vee formation plate 11.Particularly, first three gusset 8 comprises three angles, and be respectively the rear base angle 8c of the first drift angle 8a, the first front base angle 8b and first, Vee formation plate 11 comprises three angles equally, is respectively the rear base angle 11c of the second drift angle 11a, the second front base angle 11b and second; In the present embodiment, first and second drift angle 8a, 11a are movably connected in the two ends of connecting rod 12 respectively; 8b, 11b are connected with body 13 respectively at first and second front base angle; After base angle 8c and second, base angle 11c is respectively arranged with front axle 9 and hind axle 10 after first, this forward and backward wheel shaft 9,10 is flexibly connected with the front and rear wheel (not shown) of mower respectively.Cutterhead (not shown) due to mowing is arranged in body 13, therefore, forward and backward set square 8 is rotated, body 13 can be regulated to be elevated, realize the adjustment of mowing height of mower.
Stepless height adjusting device is fixedly installed on body 13 and connecting rod 12, and as shown in Figure 1, this stepless height adjusting device comprises tooth bar 7, geared parts 3, locking wheel 4, knob 1, upper fixed cover 2, lower fixed cover 6, flexible member 5.Wherein, tooth bar 7 is fixedly installed on connecting rod 12; Geared parts 3 and tooth bar 7 engage each other, and rotate this geared parts 3, tooth bar 7 can move by drivening rod 12 occurred level, thus causes forward and backward set square to swing around connecting rod 12; Locking wheel 4 is housed in geared parts 3, and engages each other with this geared parts 3; Knob 1 passes geared parts 3, and matched with locking wheel 4; Lower fixed cover 6 is fixedly mounted on body 13, and matched with geared parts 3, and locking wheel 4 and flexible member 5 are housed between lower fixed cover 6 and geared parts 3, and flexible member 5 is between locking wheel 4 and lower fixed cover 6; Upper fixed cover 2 is mutually permanently connected with lower fixed cover 6, and geared parts 3, locking wheel 4 and flexible member 5 are all housed between fixed cover 2 and lower fixed cover 6, and knob 1 partial receipt is between upper fixed cover 2 and lower fixed cover 6.
With further reference to Fig. 1 to Fig. 4, geared parts 3 comprise fixed cover be located at socket part 3a on lower fixed cover 6, to be arranged on above the 3a of socket part and with the intermeshing tooth-like part 3b of the tooth bar 7 and end-tooth 3c that is arranged in the 3a of socket part, this geared parts 3 also has central through hole 3d, in the present embodiment, this central through hole 3d is mounting hole, end-tooth 3c is arranged on the inside top surface of socket part 3a, and is centered around outside central through hole 3d.
Knob 1 comprises top cover 1a and swing arm 1b, the wherein mating shapes of the shape of swing arm 1b cross section and the central through hole 3d of geared parts 3, be all kidney-shaped, therefore after swing arm 1b inserts geared parts 3, rotating cap 1a, swing arm 1b can rotate by driven gear parts 3, and engages each other due to geared parts 3 and tooth bar 7, therefore can be the rectilinear motion of connecting rod 12 by the converting rotary motion of swing arm 1b.
Locking wheel 4 is face gear, and namely the gear teeth circumferentially are arranged on end face, and knob 1 can pass geared parts 3, and be connected with locking wheel 4, particularly, the bottom of swing arm 1b is provided with screw rod 21, the center of locking wheel 4 is provided with screw 22, screw rod 21 is threaded mutually with screw 22.This locking wheel 4 is housed between lower fixed cover 6 and socket part 3a movably simultaneously, and engages each other with the end-tooth 3c of geared parts 3.
Flexible member 5 is spring in the present embodiment, and it can be locking wheel 4 and provides an active force upwards, and locking wheel 4 is closely engaged with geared parts 3; When locking wheel 4 engages with geared parts 3, geared parts 3 cannot rotate, but, when with hand knob 1 downwards on time, flexible member 5 shrinks, and locking wheel 4 departs from geared parts 3 and is connected, and geared parts 3 is rotatable.
Upper fixed cover 2 fixed cover is located on lower fixed cover 6, it comprises the first resettlement section 2a and the second resettlement section 2b, geared parts 3, locking wheel 4 and spring 5 are all housed between this first resettlement section 2a and lower fixed cover 6, and the second resettlement section 2b is then set on connecting rod 12 and tooth bar 7.
Shown in Fig. 5 and Fig. 6 is stepless height adjusting device rotation status, in the present embodiment, first presses knob 1 downwards with hand, cause locking wheel 4 to move down, and extrude flexible member 5, make it there occurs contraction distortion, simultaneously because locking wheel 4 moves down, thus depart from the connection with geared parts 3; Then, turn clockwise knob 1, its driven gear parts 3 are turned clockwise, so just cause tooth bar 7, connecting rod 12, first drift angle 8a and the second drift angle 11a to move horizontally backward, and be movably arranged on front and rear wheel due to forward and backward wheel shaft 9,10, and front and rear wheel height cannot change, thus result in first and second front base angle 8b, 11b and move upward, therefore body 13 moves upward, and mowing height improves.Same principle, when knob 1 is rotated counterclockwise, body 13 moves downward, and mowing height reduces.
Shown in Fig. 7 and Fig. 8 is stepless height adjusting device locking state, particularly, after mowing height of mower is adjusted to correct position, unclamp knob 1, flexible member 5 resiles, thus cause locking wheel 4 to rise, and closely engage with geared parts 3, therefore, geared parts 3 cannot rotate motion, tooth bar 7 and connecting rod 12 also cannot move by occurred level, and therefore mowing height of mower cannot regulate, and is in locking state.
In sum, in high-low limit value, this stepless height adjusting device can regulate the mowing height of mower in arbitrary height, there is not the restriction of gear, and only needs operation knob 1, and it is extremely convenient, simple and easy to operate.
It is pointed out that above-mentioned preferred embodiment is only and technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
