Abstract
The utility model relates to the reequipment of an air induction system for air suction type sower which relates to a seeding machinery in the agricultural machinery. The modified air induction system for air suction type sower primarily redesigns a set of a power input shaft and wheel system adding a freewheel clutch device, and the function of the redesign is that the service life of the two-stage belt of the air induction system for air suction type sower is prolonged and work efficiency and seeding work quality are raised.
Description
The utility model relates to agricultural machinery aspect seeding machinary, particularly a kind of repacking of pneumatic seeder induced draught system.
The main power input shaft by tractor of the blower fan of more widely used pneumatic seeder rotation at present comes transferring power, main effect is to provide the work facility for the pneumatic seeder induced draught system, the power output that is tractor connects universal coupling, make the draught fan impeller high speed rotating by the two-stage V belt, make air chamber produce negative pressure and reach and inhale the purpose of planting sowing, as seen the induced draught system of pneumatic seeder is its main aspiration workpiece, the blower fan rotation of at present common pneumatic seeder and the number of moving part that makes it to reach desirable are realized through the speedup system, its power is input as direct loading, so belt very easily elongates or ruptures, and also being easy to generate breaks broadcasts empty seedling situation because of wind-force does not increase when the parking cycling start.
The utility model is reequiped at the problem that prior art exists, and provides a kind of simple in structure, easily the induced draught system that installs a kind of freewheel clutch structure additional of processing and manufacturing.
The utility model is achieved by following manner, and a kind of induced draught system that is retrofitted on the pneumatic seeder comprises power input shaft and goes up belt pulley and the freewheel clutch of installing, and freewheel clutch is fastened on the side of belt pulley.The effect of installing freewheel clutch additional mainly is prolongation pneumatic seeder induced draught system belt service life, increases work efficiency and the seeding operation quality.
Pneumatic seeder induced draught system draught fan impeller revolution need reach 4400 rev/mins and can enter normal duty, and only 500-600 rev/min of the power take-off speed of supporting tractor, illustrate that this induced draught system needs speedup work, because the motive power of pneumatic seeder is input as direct loading, so staring torque is bigger, and in the moment of cutting off the power input (tractor gearshift in as operation, turn round in the edge of a field, or because of other situation temporary parking etc.) poly-right increase of the anti-phase moment of resistance, and former induced draught system also will keep corresponding inertia torque simultaneously, thereby impel the pilled-in selvedge of belt and the anxious poly-alternation of slack list stress and rupture or elongates, start or when stopping also can producing a large amount of frictional heats and make the belt inefficacy.
When pneumatic seeder is turned in work, tractor must interim cut off power output, and starting torque is bigger when starting once more, makes belt produce friction, simultaneously induced draught system reaches number of moving part needs certain hour, then be easy to generate as on-line operation disconnectedly broadcast, empty seedling situation.
The utility model compared with prior art has the characteristics of following several respects:
1, when tractor cuts off power output, the draught fan impeller of pneumatic seeder and the inertia of belt pulley can break away from power input shaft control by freewheel clutch and keep corresponding inertia torque.
2, because of freewheel clutch can surmount separation, clutch separation work when promptly passive rotating speed inertia is higher than initiatively rotating speed, when passive rotating speed is lower than initiatively rotating speed then with main transmission run-in synchronism.
3, because of freewheel clutch surmount separation when then having avoided cutting off power the moment of resistance of moment increase and damage the belt phenomenon.
4, can overcome in the operation because of what of short duration shutdown produced and disconnectedly broadcast sky seedling situation, thereby strengthen land utilization rate and output capacity.Its social benefit can not be estimated.

Among the figure: 1 freewheel clutch overcoat; 2 belt pulleys; 3 bearings; 4 power input shafts; 5 rollers; 6 freewheel clutch wheel hubs; 7 flat keys; 8 fixed bolt holes; The endoporus of 9 regular convex concaves; 10 with the belt pulley composition surface; 11 fixed bolt holes; 12 with freewheel clutch overcoat composition surface; 13 install the position of bearings; 14 install the position of bearings; 15 install the position of bearings; 16 keyways; 17 spindle nose splines; 18 Ka Tai; 19 roller working faces; 20 keyways; 21 wheelboss inner holes; The all working faces of 22 rollers unit; The installation site of 23 freewheel clutches; 24 blower fans.
Most preferred embodiment of the present utility model, a kind of induced draught system component assembly that is retrofitted on the pneumatic seeder shown in Fig. 1 general structure component drawings comprises power input shaft 4 belt pulleys 2 and freewheel clutch overcoat 1 roller, 5 wheel hubs 6 and flat key 7 and the bearing 3 fixed on it.Feature of the present utility model is: the key connected mode of design former belt pulley of cancellation and axle, changing bearing 3 into supports, ring and power input shaft 15 interference fit in the bearing 3, bearing 3 outer shrouds and belt pulley endoporus 13 interference fit, simultaneously wheel hub 6 endoporus 21 of freewheel clutch being bumped into 16 with power input shaft 4 with flat key 7 is connected fastening with 20 places, freewheel clutch overcoat 1 can penetrate on the side 12 that 8 and 11 places are fastened on belt pulley with bolt, also can adopt closing-up.Freewheel clutch wheel hub 6 is the claw type structure, it can be four paws shape, also can be three claw types, also can be processed into the multijaw shape of other shape, should depending on the circumstances or the needs of the situation decide, the roller 5 that is equipped with suitable specification and quantity at wheel hub 6 and 1 in overcoat can play the overdrive clutch effect through 18,19,22 and 9 interphase interactions, and spindle nose spline 17 is connected the power that can import tractor by universal coupling with tractor motive power output shaft.
Present technique can produce large, medium and small all size according to actual conditions, is applied on various types of pneumatic seeder tools, also can be retrofitted to thresher, cracker, return straw into soil machine etc. other mechanically to satisfy the needs of agricultural.
