Embodiment
Be described further as follows below in conjunction with accompanying drawing 1-4 to the technical scheme of hay rake structure described in the utility model.
As shown in Figure 1, the power of tractor output drives through universal joint transmission 1 flywheel 2 that is arranged on transfer case 3 power shafts and rotates, through transfer case 3 with power distribution to the hinge wheel 13 on the crank axle of compressing mechanism 4, minor sprocket 15 by chain-driving and final drive shaft 14 seam again, thereby with transmission of power to final drive shaft 14, be cemented in the drive bevel gear 16 of final drive shaft 14 axle heads and driven wheel of differential 17 engagements that are cemented in main crank axle 22, with transmission of power to main crank axle 22.Final drive shaft 14 and main crank axle 22 all are fixed on the left support plate 20 of feed chamber 5 by bearing.as shown in Figure 4, for guaranteeing the stability of hay rake structure operation, driven main crank 8b and driven auxiliary crank 9b are set respectively on the right support plate 21 of feed chamber 5, its axle center is concentric with main crank 8a axle and auxiliary crank 9a axle respectively, the main crank 8a and the driven main crank 8b that are cemented in main crank axle 22 axle heads are connected to become the two end supports structure by the axle A29 that has strong market potential, the auxiliary crank 9a that is cemented in auxiliary crank axle 23 axle heads be connected auxiliary crank 9b and connect by the axle B30 that has strong market potential and also become the two end supports structure, guarantee that so the stable grass of hugging of described hay rake structure moves under the stalk transporting resistance.
To shown in Figure 4, it is secondary that the main crank 8a of described hay rake structure is connected to form turnover by keeper 24 and first connecting rod 10 as Fig. 2, and keeper 24, first connecting rod 10 and hug fixed being integrated of careless pawl 12 make and hug the extension rod that careless pawl 12 becomes first connecting rod 10.It is secondary that auxiliary crank 9a is connected to form turnover by sleeve 25 and second connecting rod 11, and first connecting rod 10 is connected to form revolute pair by short pin shaft 26 and second connecting rod 11.In order to cushion the inertia force of described hay rake structure member when running up, install respectively an extension spring 27 in the both sides of first connecting rod 10, cover has a stage clip 28 on second connecting rod 11.Be consolidated with respectively drive sprocket 18 and driven sprocket 19 on main crank axle 22 and auxiliary crank axle 23, make main crank 8a and auxiliary crank 9a constant speed in the same way around axle center revolution separately by chain.Like this, described hay rake structure 6 is under main crank 8a and the common driving of auxiliary crank 9a, drive by first connecting rod 10 and second connecting rod 11 and hug the turning, left side that careless pawl 12 can stretch into feed chamber 5, make and hug careless pawl 12 and walk out and hug the grass required track that do not block up, the stalk that pickup 7 is picked up is hugged into discharge chambe, then compressed the square bale of predetermined density by compressing mechanism 4.
Described hay rake structure utilizes the more abundant characteristics of five-rod coupler-point curve, and the track of generation is compared with existing crank-rocker style hay rake structure, can overcome largely the defective that there is defeated careless blind area in feed chamber, has the characteristics that grass is smooth and stability is high of hugging.
