Abstract
The utility model discloses a motor -driven sword reciprocating motion device mows, motor -driven sword reciprocating motion device mows in this scheme, including the cam, the revolute pair, fix drive crank and driven crank in the revolute pair, elastomeric element and with the push rod that the sword is connected that moves of lawn mower, the coaxial rotation respectively of revolute pair and cam is fixed in the frame, drive crank tip matches with cam outer fringe groove, driven crank tip drives the push rod with the push rod cooperation and makes axial motion, this push rod and guide rail sliding fit, the one end of push rod is passed through elastomeric element and is connected in the frame, the structure principle is simply difficult to be got stuck by the weeds piece.
Description
Technical field
The utility model relates to a kind of mower moving knife reciprocator.
Background technology
Along with the raising that people require quality of the life, more and more paying attention to the green ring of living environment, plant grass, planting flower, plant tree is all good selection, once after planting these plants upper, often safeguard it: water, prune with regard to needs.The lawn of particularly planting, if pruned irregular weeds not in time, it is general that the lawn being easy to originally to appreciate for people becomes shrub.Traditional bothersome effort of artificial pruning, therefore usually adopt mower now, relatively artificial mowing, not only efficiency is higher, and the plant pruned is more regular.According to the working method of mower, be divided into reciprocating and rotary, shuttle low mower relies on the mutual shear motion cutting herbage of moving knife and stationary knife on cutter, namely a wherein very important device is produce reciprocating mechanism, and this mechanism can make the relative stationary knife generation of moving knife do relatively reciprocating motion.Existingly provide reciprocating mechanism; forget to pursue the portable of mower entirety; very compact often by global design; during work; often have weeds chip and enter inside; weeds chip enters compact structure and often causes getting stuck of machine, needs often to keep in repair, and adds cost virtually.
Utility model content
The utility model is intended to provide a kind of structural principle simple mower moving knife reciprocator.
Mower moving knife reciprocator in this programme, comprise cam, revolute pair, the push rod that is fixed on driving crank in revolute pair and driven crank, elastomeric element and is connected with the moving knife of mower, revolute pair and cam rotate respectively and are fixed in frame, driving crank end is mated with cam peripheral groove place, driven crank end coordinates with push rod and drives push rod to do axially-movable, this push rod coordinates with slide, and one end of push rod is connected in frame by elastomeric element.
The operation principle of this programme is as follows: idle time, the end coupling of driving crank is in the groove of cam, when cam driven device driven rotary, drive driving crank to rotate simultaneously, driving crank is by revolute pair and driven crank synchronous rotary, driven crank handle turns push rod axially moves in guide rail, the convex apexes rotating over cam when the end of driving crank rotates, driven crank drives driving crank synchronous backward by revolute pair, now the end of driving crank will be mated with the groove of the cam in rotation again, complete the motion of one-period since then, in like manner, next cycle can be carried out, thus realize driving moving knife to move back and forth.
The technique effect of this programme, can realize driving moving knife to move reciprocatingly by the cooperation of crank, cam and elastomeric element, structural principle is simple, due to the relatively independent setting of each parts, even if weeds chip enters machine intimate, there is larger activity space between parts, be not easy to occur getting stuck, thus the service life of machine is increased.
Further, push rod radial direction is provided with groove, and the end of driven crank is mated with groove, push rod and driven crank relatively independent, when occurring damaging for one, not easily there is chain reaction thus causing another damage.
Further, push rod comprises thrust portion and sliding part, and this thrust portion coordinates with driven crank, and described sliding part coordinates with slide, and this thrust portion is threaded with sliding part, during the relatively independent damage of each several part, easily changes.
Further, driven crank is detachably fixed in revolute pair, and convenient for maintaining is changed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: guide rail 1, push rod 2, extension spring 3, driving crank 5, cam 6, frame 7, driven crank 8, revolute pair 9.
Embodiment 1:
Substantially as shown in Figure 1:
Cam 6 rotates and is fixed in frame 7, transmit power by motor, cam 6 cylindrical is uniform arranges eight grooves, and driving crank 5 and driven crank 8 screw thread are fixed in revolute pair 9, revolute pair 9 and cam 6 are coaxially fixed in frame 7, the end of driving crank 5 and the matching grooves of cam 6.
Push rod 2 comprises thrust portion and sliding part, and thrust portion is provided with radial groove, and mate with it in the radial groove in end of driven crank 8, sliding part and guide rail 1 are slidably matched, and sliding part and thrust portion screw thread are fixed together.
The opposite end that the thrust portion of push rod 2 is connected with sliding part is connected in frame 7 by extension spring 3, and sliding part and moving knife link.
Dextrorotation rotating cam 6 during work, driving crank 5 is rotated, driving crank 5 is by revolute pair 9 and driven crank 8 synchronous axial system, and then driven crank 8 drives push rod 2 to slide axially in guide rail 1, when the projecting tip of cam 6 groove is crossed in driving crank 5 end, under the active force of extension spring 3, make the counter motion of driven crank 8, and then rotated by revolute pair 9 and driving crank 5 synchronous backward, now driving crank 5 end fits in groove again with the cam 6 turned clockwise, and realizes the motion of one-period.
Embodiment 2:
The same Fig. 1 of embodiment accompanying drawing, the extension spring 3 in embodiment 1 is replaced by spring, and rotating to be of cam 6 is rotated counterclockwise, and can realize the technique effect in embodiment 1 equally.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
