Description
Technical field
The present invention relates to stalk cutting bundling technical field, provide especially a kind of for the careless device of hugging of straw field pickup binder.
Background technology
Along with the development of agricultural mechanization, combine uses in crop harvesting in a large number, abandons among the farmland but machine is incorporated as more than one hundred million tons of stalks of deposits yields, needs artificial or processing collected and tie up by binder to stalk.Current, various places government forbids that the peasant directly carries out burning disposal to stalk under the requirement of building Ecological Society, straw electric generation plant and the straw gasification station of some have been set up simultaneously, for stalk comprehensive utilization finds a way out, the agricultural crop straws such as the rice wheat that so just needs to use binder to gather in the crops and be dispersed in a large number the field, corn.But; the ubiquitous problem of towed binder on the market is: when the stalk that crank-rocker style hay rake structure is picked up pickup is transported to discharge chambe from feed chamber; there is one at the turning, left side of feed chamber and hugs careless blind area; this piece blind area can be caused stalk to carry and be stopped up; usually cause the closed-down manual cleaning to be stopped up; affect the continuity of complete machine work, reduced stalk cutting efficient.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, a kind of supporting novel hay rake structure of straw field pickup binder that is is provided, solve stalk and have the problem of stopping up in feed chamber corner.
Technical scheme of the present invention is,The main feed chamber of described hay rake structure (being equivalent to frame), main crank, driven main crank, auxiliary crank, driven auxiliary crank, first connecting rod, second connecting rod and hug careless pawl and form, it is secondary that main crank is connected to form turnover by keeper and first connecting rod, keeper, first connecting rod and hug that careless pawl is fixed to be integrated make to hug the extension rod that careless pawl becomes first connecting rod.It is secondary that auxiliary crank is connected to form turnover by sleeve and second connecting rod, and first connecting rod is connected to form revolute pair by short pin shaft and second connecting rod, makes described hay rake constitute a kind of two-freedom link-type hay rake structure.Main crank and auxiliary crank are cemented in respectively the axle head of main crank axle and auxiliary crank axle, main crank axle and auxiliary crank axle are arranged on the gripper shoe of sidewall of feed chamber, the fixed drive sprocket of difference and driven sprocket on main crank axle and the auxiliary crank axle, drive sprocket turns round respectively main crank and auxiliary crank by the chain-driving driven sprocket in the same way around the axle center constant speed of main crank axle and auxiliary crank axle.
Two driving links of described hay rake structure are respectively main crank and auxiliary crank, the projecting shaft of main crank axle and driven main crank is supported on the left support plate and right support plate of feed chamber with one heart by bearing, the projecting shaft of auxiliary crank axle and driven auxiliary crank also is supported on the left support plate and right support plate of feed chamber with one heart by bearing, the main crank and the driven main crank that are cemented in main crank axle axle head are connected to become the two end supports structure by the axle A that has strong market potential, the auxiliary crank that is cemented in auxiliary crank axle axle head be connected auxiliary crank and connect by the axle B that has strong market potential and also become the two end supports structure, purpose is the stability that guarantees described hay rake structure operation under the stalk transporting resistance.
The invention has the beneficial effects as follows: described hay rake structure can generate than the more excellent track of existing crank-rocker style hay rake structure, easily manufactured, assembling is simple, can effectively alleviate the obstruction of stalk corner in feed chamber, has improved binder operating efficiency and stability.

Embodiment
Be described further as follows below in conjunction with accompanying drawing 1-4 to the technical scheme of hay rake structure of the present invention.
As shown in Figure 1, the power of tractor output drives the flywheel 2 that is installed on transfer case 3 power shafts through universal joint transmission 1 and rotates, through transfer case 3 with power distribution to the hinge wheel 13 on the crank axle of compressing mechanism 4, the 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 like this under the stalk transporting resistance that described hay rake structure is stable to hug the grass action.
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 such as Fig. 2, and keeper 24, first connecting rod 10 and hug careless pawl 12 fixed being integrated 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, at second connecting rod 11 covers a stage clip 28 is arranged.On main crank axle 22 and auxiliary crank axle 23, be consolidated with respectively drive sprocket 18 and driven sprocket 19, make main crank 8a and auxiliary crank 9a constant speed in the same way around separately axle center revolution by chain.Like this, described hay rake structure 6 is under main crank 8a and the common driving of auxiliary crank 9a, hug the turning, left side that careless pawl 12 can stretch into feed chamber 5 by first connecting rod 10 and second connecting rod 11 drives, 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, compressed again 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.
