Abstract
The utility model provides a manual tensioning wheel for a driving belt of a thresher, which comprises a tensioning wheel (1), a guide block (2), a guide trough plate (3), a tension pull rod (4), a positioning block (5), a positioning pin (6), a tension spring (7), a pressure spring (8), a positioning spring sleeve (9) and a positioning handle (10). The utility model has the advantages of simple structure, convenient operation and low manufacturing cost; and a power machine of miniature agricultural machinery can be enlarged from an electric motor to a diesel or a petrol engine only through mounting a set of small mechanism, thereby realizing no-load starting. The tensioning wheel is applicable to agricultural machineries and threshers.
Description
Technical field:
The utility model relates to a kind of manual device, especially a kind of tension device of power transmission belt.
Background technique:
Miniature farm machineries such as existing small-sized rice-wheat thresher, universal thrashing machine, majority is not provided with engaging and disengaging gear, adopts petrol engine, when diesel engine is used as power the source, starting of petrol engine, diesel engine is very difficult, even power adopts motor, because voltage is low, start also relatively difficulty in the remote mountain areas; And being provided with engaging and disengaging gear, every of its cost cost needs to increase 70-100 unit, the corresponding economic burden that increases the peasant.
Summary of the invention:
The utility model is intended to overcome above-mentioned shortcoming, has both made things convenient for the peasant to use, and reduces peasant's economic burden again, and is simple in structure, easy to operate, and suitable remote mountain areas is promoted agricultural machinery and used.The utility model is made of Idle wheel [1], guide pad [2], guide groove plate [3], tensioning pull bar [4], positioning block [5], locating stud [6], extension spring [7], stage clip [8], positioning spring cover [9], position fixing handle [10].Guide groove plate [3] is adorned on the setting a roof beam in place of solid central rack below power rack, and guide pad [2] passes the guiding groove of guide groove plate [3], and the upper end of guide pad [2] and tensioning pull bar [4] connect firmly.The front end of tensioning pull bar [4] is equipped with a bearing, and Idle wheel [1] is installed on the bearing.One end of extension spring [7] hangs over the front end of tensioning pull bar [4], and the other end of extension spring [7] hangs on the setting a roof beam in place of central rack.The tail end dress of tensioning pull bar [4] spurs handle admittedly, and the rear portion of tensioning pull bar [4] connects firmly a positioning block [5] that is shaped on 4-8 positioning hole; Locating stud [6] becomes 90 ° of installations with positioning block [5], and the pin head of locating stud [6] front end inserts in the interior location of positioning hole on the positioning block [5].The foot piece of locating stud [6] passes stage clip [8], positioning spring cover [9], the solid position fixing handle [10] of tail end dress.Stage clip [8] is loaded in the positioning spring cover [9], and positioning spring cover [9] dress is solid on frame.The utlity model has simple in structurely, easy to operate, cost of production is low, only installs once the little mechanism of cover to make the power engine of miniature farm machinery expand diesel engine, petrol engine to by motor, realizes characteristics such as idling lotus startup.Suitable being installed on farm machinery, the threshing machine used.
Description of drawings:
Fig. 1 is the structure installation diagram, and Fig. 2 is that the A of Fig. 1 is to partial sectional view.
Embodiment:
By Fig. 1, Fig. 2, constitute by Idle wheel [1], guide pad [2], guide groove plate [3], tensioning pull bar [4], positioning block [5], locating stud [6], extension spring [7], stage clip [8], positioning spring cover [9], position fixing handle [10].Guide groove plate [3] is made with angle steel.Guide pad [2], tensioning pull bar [4], positioning block [5], locating stud [6], positioning spring cover [9] are made with A 3 steel.The bearing of tensioning pull bar [4] front end dress is selected the ball bearing of Z6202-6204 for use, and Idle wheel [1] is cylinder iron cast.Extension spring [7], stage clip [8] are made quenching with Subsequent tempering with Spring Steel Wire.Position fixing handle [10], that tensioning pull bar [4] tail end is adorned solid pulling handle is made of plastic.Pull back position fixing handle [10] with hand when diesel engine, gasoline engine starting, locating stud [6] and positioning block [5] are thrown off, and loosen and realize that the idling lotus starts at the effect underdrive belt of extension spring [7].After diesel engine, gasoline engine starting work well, with the drivign belt tensioning, spur locating stud [6] location again, realize the proper functioning running with the pulling handle that pulls tensioning pull bar [4] tail end.
