Abstract
The utility model discloses a kind of mower tensile force adjustable certainly walk device, comprise motor-driven driving wheel, driving wheel is connected with driven pulley by belt, driven pulley drives from walking device walking, the described device of certainly walking comprises interconnective upper shell and lower house, between upper shell and lower house, be fixed with tensioning plate, tensioning plate side is provided with tooth bar, and cogged adjusting bolt is established in the tooth bar end that is connected with a joggle; Described upper shell is provided with the inside cavity that lower house forms the power transmission shaft that is connected driven pulley, and power transmission shaft connects the central rotating shaft of mower trailing wheel by actuator drives.The utility model rotates the gear driving rack that makes end by adjusting bolt, tensioning plate can be moved left and right in the horizontal direction, and then the power transmission shaft left and right horizontal having realized in upper shell and lower house cavity moves, thereby change the spacing between driving wheel and driven pulley, reach the technical purpose of adjusting tensioning force of belt, extended belt and certainly walked the service life of device.
Description
Technical field
What the utility model related to a kind of mower walks device certainly, specifically a kind of mower with tensile force adjustable certainly walk device.
Background technology
Mower uses for all having in ci ty gardens management, maintenance and family's garden, farm widely at present.Mower be the driving wheel utilizing on driven by motor mower from walking device, rotated by two trailing wheels on belt drives driven pulley band motor mower by driving wheel, realize mower mow process in automatically forward walking.Traditional tensioning of certainly walking its belt of device generally regulates by spring, due to the strain of spring self with and the position tensile force of controlling belt after fixing lack adjusting function, caused and certainly walked too early the scrapping or the technical problem such as belt is aging of device.How to improve from the driving belt service life of walking device, or to certainly walking the driving belt of device, tensile force regulates as required, is the object that those skilled in the art study always.
The Chinese utility model patent patent No. 201120296036.0 discloses a kind of embedded clutch of mowing machine, belong to the technical field of mower clutch, comprise being arranged in casing, being placed in gamp tooth and driven cover on driving shaft, and be fixedly connected with between gamp tooth and driven cover; On gamp tooth, engagement is provided with small bevel gear, and the tooth handle of small bevel gear penetrates and is positioned at the belt pulley axis hole of casing outside and is fixedly connected with belt pulley; Be positioned on the driving shaft of driven cover homonymy and be installed with guide rail, and on guide rail, be provided with the active cover matching with driven cover; Initiatively put the shift fork being provided with swing arm, reset tension spring, and swing arm and reset tension spring are installed in casing outside.This kind of relative complex structure of technical scheme do not adopt the regulation technology of belt tension, there is no the technical clarification of this respect yet.
Utility model content
The utility model provides a kind of simple in structure, safety, the mower on service life with tensile force adjustable certainly walk device.
A kind of mower with tensile force adjustable certainly walk device, comprise motor-driven driving wheel, driving wheel is connected with driven pulley by belt, driven pulley drives from walking device walking, the described device of certainly walking comprises interconnective upper shell and lower house, between upper shell and lower house, be fixed with tensioning plate, tensioning plate side is provided with tooth bar, and cogged adjusting bolt is established in the tooth bar end that is connected with a joggle; Described upper shell is provided with the inside cavity that lower house forms the power transmission shaft that is connected driven pulley, and power transmission shaft connects the central rotating shaft of mower trailing wheel by actuator drives.This kind rotates from walking device the gear driving rack that makes end by adjusting bolt, tensioning plate can be moved left and right in the horizontal direction, and then the power transmission shaft left and right horizontal having realized in upper shell and lower house cavity moves, thereby change the spacing between driving wheel and driven pulley, and then the tensile force of adjusting belt, extend belt and certainly walked the service life of device.
Described transmission device comprises to be located at the first cone tooth of end part of driving shaft and to be located at the cone of second on central rotating shaft tooth, and the first cone tooth and the second cone tooth are intermeshing, and raising power transmission shaft drives the stability of central rotating shaft and trailing wheel.
Be connected by conical belt with driven pulley as the preferred driving wheel of structure, increase transmission force.
The utility model rotates the gear driving rack that makes end by adjusting bolt, tensioning plate can be moved left and right in the horizontal direction, and then the power transmission shaft left and right horizontal having realized in upper shell and lower house cavity moves, thereby change the spacing between driving wheel and driven pulley, reach the technical purpose of adjusting tensioning force of belt, extended belt and certainly walked the service life of device.
Brief description of the drawings
Be illustrated in figure 1 the utility model mower tensile force adjustable certainly walk the main TV structure schematic diagram of device.
Embodiment
As shown in Figure 1 a kind of mower with tensile force adjustable certainly walk device, comprise motor-driven driving wheel 1, driving wheel 1 is connected with driven pulley 2 by belt 3, driven pulley 2 drives from walking device walking, comprise interconnective upper shell 7 and lower house 8 from walking device, between upper shell 7 and lower house 8, be fixed with tensioning plate 5, tensioning plate 5 sides are provided with tooth bar, and cogged adjusting bolt 6 is established in the tooth bar end that is connected with a joggle; The inside cavity that described upper shell 7 forms with lower house 8 is provided with 2 power transmission shafts 4 that are connected driven pulley, and power transmission shaft 4 connects the central rotating shaft 8 of mower trailing wheel by actuator drives, realizes trailing wheel and is certainly walking walking under device driving.Transmission device comprises to be located at the first cone tooth of power transmission shaft 4 ends and to be located at the cone of second on central rotating shaft 8 tooth, and the first cone tooth and the second cone tooth are intermeshing.
Be connected by conical belt with driven pulley 2 as the preferred driving wheel 1 of structure.
The foregoing is only an embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
