Abstract
The utility model relates to the field of hay mowers, in particular to a bidirectional belt tensioning device for a hay mower. The bidirectional belt tensioning device for the hay mower comprises a tensioning device body which is composed of a left rubber wheel, a right rubber wheel and a connection transverse board, the left rubber wheel is installed at the left end of the connection transverse board, and the right rubber wheel is installed at the right end of connection transverse board. The traditional unidirectional tensioning mode of a belt of a hay mower is changed to be the bidirectional tensioning mode. The bidirectional belt tensioning device for the hay mower is simple in structure and good in tensioning effect, reduces the requirements for the quality of the belt, a driving belt wheel and a driven belt wheel, and accordingly reduces the production cost and the later maintenance cost.
Description
[technical field]
The utility model relates to mower field, the particularly two-way tensioning apparatus of a kind of mowing leather machine belting.
[background technology]
Mower be a kind of be used to cut the grass on a lawn, the machine tool of vegetation etc., it is comprised of cutterhead, engine, road wheel, running gear, blade, handrail, control section, the belt stretcher of traditional mower is owing to being unidirectional tensioning, the coplanar of principal and subordinate's belt wheel had relatively high expectations, thereby selecting principal and subordinate's belt wheel limitation large, both thereby increased cost, also increased maintenance cost to later maintenance.
[utility model content]
The purpose of this utility model is for the defective of prior art and deficiency, provide a kind of simple in structure, the two-way tensioning apparatus of a kind of mowing leather machine belting reasonable in design, easy to use, it adopts the belt tension with traditional mower to become two-way tensioning by unidirectional tensioning, it has simple in structure, tension effects is good, has reduced the quality requirement to belt and principal and subordinate's belt wheel, thereby has reduced production cost and later maintenance cost.
For achieving the above object, the technical solution adopted in the utility model is:
The two-way tensioning apparatus of a kind of mowing leather machine belting described in the utility model, it comprises tensioner body, described tensioner body is by left rubber wheel, right rubber wheel and be connected transverse slat, and the left end of described connection transverse slat is provided with left rubber wheel, and the right-hand member of this connection transverse slat is provided with right rubber wheel.
Further, be provided with left rubber wheel belt grooves on the excircle of described left rubber wheel, this left rubber wheel circle centre position is provided with left rubber wheel built-in bearing.
Further, be provided with right rubber wheel belt grooves on the excircle of described right rubber wheel, this right rubber wheel circle centre position is provided with right rubber wheel built-in bearing.
Further, described connection transverse slat left side is provided with back-moving spring, and this back-moving spring outer end is connected with the body of mower.
Further, described connection transverse slat right side is provided with cable wire, and this cable wire outer end is connected with the handgrip of mower.
After adopting said structure, the utility model beneficial effect is: the two-way tensioning apparatus of a kind of mowing leather machine belting described in the utility model, employing becomes two-way tensioning with the belt tension of traditional mower by unidirectional tensioning, it has simple in structure, tension effects is good, reduce the quality requirement to belt and principal and subordinate's belt wheel, thereby reduced production cost and later maintenance cost.

[embodiment]
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation only are used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, the two-way tensioning apparatus of a kind of mowing leather machine belting described in the utility model, it comprises tensioner body 3, described tensioner body 3 is by left rubber wheel 31, right rubber wheel 32 and be connected transverse slat 33, the left end of described connection transverse slat 33 is provided with left rubber wheel 31, and the right-hand member of this connection transverse slat 33 is provided with right rubber wheel 32.
Be provided with left rubber wheel belt grooves on the excircle of described left rubber wheel 31, these left rubber wheel 31 circle centre positions are provided with left rubber wheel built-in bearing.
Be provided with right rubber wheel belt grooves on the excircle of described right rubber wheel 32, these right rubber wheel 32 circle centre positions are provided with right rubber wheel built-in bearing.
Described connection transverse slat 33 left sides are provided with back-moving spring, and this back-moving spring outer end is connected with the body of mower.
Described connection transverse slat 33 right sides are provided with cable wire, and this cable wire outer end is connected with the handgrip of mower.
The utility model installation method is, belt 2 is passed left rubber wheel belt grooves on the left rubber wheel 31 of tensioner body 3 and the right rubber wheel belt grooves on right rubber wheel 32, in the belt grooves of left end winding on driven pulley 1 of belt 2, this driven pulley 1 is connected with the grass-cutting head of mower, in the belt grooves of right-hand member winding on driving pulley 4 of belt 2, this driving pulley 4 is connected with the engine of mower.Be movably arranged on the body of mower in the middle part of the connection transverse slat of tensioner body 3.
The utility model in use, when driving pulley 4 rotates, be not arranged on if do not move to the cable wire that connects transverse slat 33 right sides, at this time tensioner body 3 does not play tension, the have the initiative pine of belt wheel 4 and driven pulley 1 of belt 2 is joined state, driven pulley 1 does not rotate, and this moment, the mower place was not in the state of not mowing; When pulling cable wire, this moment, tensioner body 3 was by clockwise rotating, driving left rubber wheel 31 and right rubber wheel 32 works simultaneously, thereby two-way tightening belt 2, this moment, belt 2 was in the tight fit state with driving pulley 4 and driven pulley 1, thereby 1 rotation of band driven pulley, this moment, mower was in the mowing state.
The two-way tensioning apparatus of a kind of mowing leather machine belting described in the utility model, employing becomes two-way tensioning with the belt tension of traditional mower by unidirectional tensioning, it has simple in structure, tension effects is good, reduce the quality requirement to belt and principal and subordinate's belt wheel, thereby reduced production cost and later maintenance cost.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
