Description
Technical Field
The utility model belongs to the technical field of the belt drive technique and specifically relates to indicate a belt tightness adjusting device.
Background
With the rapid development of agricultural mechanization, domestic agricultural planting is basically mechanized. For example, the straws are smashed and thrown back to the farmland by the field machine to realize farmland fertilization and avoid straw combustion, a belt of the straw fertilizing machine is driven by two belt pulleys, the straw fertilizing machine belongs to one of mechanical transmissions, and the straw fertilizing machine utilizes friction between the belt and two wheels to transmit motion and power. The belt is the most prone to causing problems in mechanical transmission, after the belt is abraded and aged, the problems that the belt is easy to fall off, the running sound is large, the output force is insufficient and the like are easily caused, at the moment, the belt needs to be disassembled and replaced, and the service life of the belt is greatly shortened.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a belt tightness adjusting device is just avoiding the belt too pine condition to appear through adjusting the take-up pulley roof pressure belt, has prolonged the life of belt greatly. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a belt tightness adjusting device, includes the mounting panel, mounting panel one side is equipped with two belt pulleys, is connected with a plurality of belts between two belt pulleys, belt top or below are equipped with the runing rest, the runing rest middle part is fixed through the pivot on the mounting panel, runing rest one end is equipped with waist type hole, waist type hole joint has the take-up pulley, the take-up pulley top is pressed a plurality of on the belt, the runing rest other end is connected with the pull rod, the pull rod is connected with elastic spring, the elastic spring other end is connected with adjusting bolt, adjusting bolt overlaps on the connecting plate soon, the connecting plate horizontal welding is in on the mounting panel.
Furthermore, connecting holes are formed in the pull rod and the adjusting bolt.
(III) advantageous effects
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a rotating adjusting bolt just can adjust the tension of take-up pulley and then the roof pressure belt, avoids the belt the condition of pine to appear, sets up waist type hole simultaneously on runing rest, further increases the control range of take-up pulley, has prolonged the life of belt greatly.
