Description

Main shaft structure for straw treatment machine

Technical Field

The utility model relates to a main shaft structure that various straw processing mechanical equipment such as straw returning, recovery, baling press used on especially relate to and need not change the main shaft, can be used for handling ridge culture and non-ridge culture crop straw through simple adjustment to and be applicable to the different ridge depths of ridge culture crop and the main shaft structure of ridge distance.

Background

During the process of processing the ridge crop straws, various straw processing and harvesting machines such as straw returning machines, recycling machines, packing machines and the like have a difficult problem of processing the straws in the furrows due to the height difference between the ridge and the furrows.

In the prior art, straw treatment and receiving machinery mainly adopts the following two modes: firstly, the movable knives or the swinging hammers with the same length are adopted to only treat the straws on the ridge platforms, the straws in the furrows are abandoned, untreated straws are burnt later, the residual straws cannot be completely treated by the scheme, and the scheme is not feasible especially under the background of environmental protection and no straw burning.

And secondly, a structure of long and short movable blades or long and short swinging hammers is adopted, namely the short movable blades or the short swinging hammers are arranged at the positions, corresponding to the ridge, of the main shaft, the long movable blades or the long swinging hammers are arranged at the positions of the ridge furrows, the long movable blades or the long swinging hammers are used for treating the straws in the ridge furrows when the main shaft rotates, and the short movable blades or the short swinging hammers are used for treating the straws on the ridge to achieve the purpose of simultaneously treating the ridge furrows and the ridge straws. This structure is also the predominant structure in the market in recent years, but has several drawbacks: 1. the length and the installation distance of the movable knife or the drop hammer are fixed, and the movable knife or the drop hammer cannot adapt to different furrow depths and ridge distances; 2. because the tool magazine is not universal, the spindle for mounting the movable tool cannot be provided with the drop hammer, and the spindle is not universal and can only be replaced; 3. for non-ridge culture crops such as rice, wheat and other straws, the long and short movable knife or the swinging hammer structure cannot be used.
