Problems solved by technology

Compared with foreign advanced models, the round balers produced by domestic enterprises have smaller overall supporting power, low intelligence, and poor reliability, especially when harvesting long rice stalks and pastures with high moisture content. The blockage of the feed inlet is serious
The feeding device of the round baler often adopts a spiral knife-roller structure to force-feed grass and materials, which improves the conveying performance of materials, but the problem of blockage has not been effectively solved
When the moisture content of the straw or pasture is high or the accumulation layer of the grass is thick, the driver fails to reduce the forward speed of the unit, which will lead to the increase of the feeding resistance of the broken grass parts, and the rotation speed of the spiral knife roller will decrease accordingly, which will easily cause material damage. Blockage at the feed inlet, resulting in damage to grass-cutting parts and other failures, seriously affecting the operating efficiency of the round baler

Embodiment Construction

[0020] Such as figure 1 As shown, when the baler is working, it is connected with the tractor through the traction frame 15, and the power output shaft of the tractor is connected with the universal joint transmission 1 of the baler, and then the power is transferred through the transfer case 5 through the transfer case transmission shaft 6. Pass it to the driving sprocket 8, and then drive the driven sprocket 11 through the chain 9, and the chain tensioning device 10 plays the role of tensioning the chain.

[0021] Such as figure 2 and Figure 5 As shown, the screw cutter roller 7 is rotatably supported on the frame 26 through the screw cutter roller shaft 20, the screw cutter roller shaft 20 is fixed with the flange 18, and the driven sprocket 11 is idly sleeved on the screw cutter roller shaft 20 , the driven sprocket 11 and the flange 18 are affixed through the safety bolt 19 to realize the rotation of the screw cutter roller 7 . The spirally arranged 4-head blade grou...

Abstract

The invention discloses a forced grass-crushing and feeding anti-blocking method and device after a round baler picks up materials, and relates to the technical field of straw harvesting and baling. By adopting a double anti-blocking protective technology that the openness of a lower jaw is adjusted by using a controller and a mechanical overload protection device is arranged, when the controller commands the movable lower jaw to enlarge the openness so as not to alleviate the load of a roll shaft of a spiral cutter or the controller fails, a safety bolt is sheared off so as to realize overload protection of the forced grass-crushing and feeding device. The device is capable of uniformly crushing and feeding grass and effectively preventing the feed inlet from being blocked, and is safe and reliable to use; and the operational efficiency of the round baler is improved.

Description

technical field [0001] The invention relates to an anti-clogging method and device for forced broken grass feeding after materials are picked up by a picker of a round baler, in particular to an anti-blocking device for forced broken grass feeding of a round baler. Background technique [0002] Round balers are more and more widely used due to their high work efficiency and low price. Compared with foreign advanced models, the round balers produced by domestic enterprises have smaller overall supporting power, low intelligence, and poor reliability, especially when harvesting long rice stalks and pastures with high moisture content. The clogging problem of the feed inlet is serious. The feeding device of the round baler often adopts a spiral knife-roller structure to force-feed grass and materials, which improves the conveying performance of materials, but the problem of blockage has not been effectively solved. When the moisture content of the straw or pasture is high or ...
