Description
Technical field
The utility model belongs to technical field of transmission equipment, especially a kind of fruit sorter chain pneumatic tensioning device.
Background technique
When sorting fruit, need longer-distance conveying, to carry out sorting and shunting, in the kind of drive, general selection is applicable to remote chain transmission.Chain transmission, because its reliable operation, nonelastic slip and skidding, has been widely used in the machinery such as agricultural, metallurgy, building, oil, chemical industry.But two sprocket wheels of chain drive are in the same face, chain is because of service wear, and the active length of chain can increase gradually, causes effective total number of teeth in engagement to reduce, causes transmission performance to decline, cause driving unit fault time serious.In order to solve problems, generally all in driving mechanism, increasing tension device, effectively improving chain, the transmission performance of band and operating life.
Existing chain stretching device includes Idle wheel and tensile force adjusting device, and existing chain stretching device structure is comparatively complicated, and component are more, and regulates the complicated operation of the tensile force adjusting device of required tension chain, poor reliability.Especially after the as easy as rolling off a log because chain wear of existing chain stretching device is elongated, can not the rate of tension of adjusting chain efficiently in time, easily cause engagement bad, sprocket wheel such as to come off at the problem.
Model utility content
(1) technical problem that will solve
The utility model is in order to overcome the rate of tension that can not adjust chain in time and tensioning device structure is complicated, the shortcoming of poor reliability, the technical problems to be solved in the utility model is to provide one can automatically by chain tension, structure is relatively simple, the fruit sorter chain pneumatic tensioning device that tension effects is good.
(2) technological scheme
In order to solve the problems of the technologies described above, the utility model provides so a kind of fruit sorter chain pneumatic tensioning device, include support fixing device, tension sprocket, upper saw pulley, gas spring, tensioning shaft and guide rod, described support fixing device is provided with " one " font guiding groove, described upper saw pulley is arranged on " one " font guiding groove, described tension sprocket is arranged on described tensioning shaft, and described upper saw pulley has two, is arranged on the two ends of described tensioning shaft respectively; Described gas spring has two, and be arranged on the inner side of described support fixing device, one end is connected with described tensioning shaft respectively, and the other end is connected with described support fixing device; Described guide rod has two, and be arranged on the outside of described support fixing device, one end is connected with described tensioning shaft respectively, the other end is connected with described support fixing device, described guide rod cylindrical is threaded.
Working principle: during installation, be arranged on by decrement biggest place by described guide rod by gas spring, tensioning shaft is now fixed by nut.After this device is fixing by support fixing device, and tension sprocket engages with the chain of required tensioning, unclamps nut, because gas spring to be produced an outside thrust and chain by compressing, makes it be in tensioning state.Because chain wear is elongated in producing, the position of tension sprocket will be regulated by the outside thrust of gas spring automatically, make whole chain be in tensioning state.
(3) beneficial effect: the utility model has and automatically adjusts rate of tension, makes the chain long period be in tensioning state, the fruit sorter chain pneumatic tensioning device that apparatus structure is relatively simple, tension effects is good.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
embodiment 1
A kind of fruit sorter chain pneumatic tensioning device, as Figure 2-3, include support fixing device, tension sprocket, upper saw pulley, gas spring, tensioning shaft and guide rod, described support fixing device is provided with " one " font guiding groove, described upper saw pulley is arranged on " one " font guiding groove, described tension sprocket is arranged on described tensioning shaft, and described upper saw pulley has two, is arranged on the two ends of described tensioning shaft respectively; Described gas spring has two, and be arranged on the inner side of described support fixing device, one end is connected with described tensioning shaft respectively, and the other end is connected with described support fixing device; Described guide rod has two, and be arranged on the outside of described support fixing device, one end is connected with described tensioning shaft respectively, the other end is connected with described support fixing device, described guide rod cylindrical is threaded.
embodiment 2
A kind of fruit sorter chain pneumatic tensioning device, as Figure 2-3, include support fixing device, tension sprocket, upper saw pulley, gas spring, tensioning shaft and guide rod, described support fixing device is provided with " one " font guiding groove, described upper saw pulley is arranged on " one " font guiding groove, described tension sprocket is arranged on described tensioning shaft, and described upper saw pulley has two, is arranged on the two ends of described tensioning shaft respectively; Described gas spring has two, and be arranged on the inner side of described support fixing device, one end is connected with described tensioning shaft respectively, and the other end is connected with described support fixing device; Described guide rod has two, and be arranged on the outside of described support fixing device, one end is connected with described tensioning shaft respectively, the other end is connected with described support fixing device, described guide rod cylindrical is threaded.
During installation, as shown in Fig. 1 (b), be arranged on by decrement biggest place by described guide rod by gas spring, tensioning shaft is now fixed by nut.After this device is fixing by support fixing device, and tension sprocket engages with the chain of required tensioning, unclamps nut, because gas spring to be produced an outside thrust and chain by compressing, makes it be in tensioning state.As shown in Fig. 1 (a), because chain wear is elongated in producing, the position of tension sprocket will be regulated by the outside thrust of gas spring automatically, make whole chain be in tensioning state.
The above embodiment only have expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion, improvement and substitute, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
