Utility model works principle, as follows:
Thresher feeding connecting gear of the present utility model is arranged on above threshing cylinder; one buttress rice straw is placed on the chain at opened type spout place; then rice straw can be sent to grain pressing rod by chain automatically; rice straw is subject to the clamping (replacing staff to grip) of grain pressing rod and chain, and spike of rice hangs down to thrashing cylinder place by gravity or other briquetting machine effects and carries out threshing operation.Can put into fast like this, automation threshing can be accomplished again, laborsavingly to save time, efficient quick.
The synchronized transmission of the utility model definition refers to that linear velocity is identical.
Grain pressing rod is located at below chain transfer mechanism, joint space-efficient effect can be accomplished under the prerequisite ensureing effective threshing time.Due in the longitudinal direction, the grain pressing rod being in below can not can not form length and add up with the opened type spout being in top; And in the height direction, by quite limited for underlying for grain pressing rod increased height distance (mainly the thickness of grain pressing rod itself), compared with the scheme above being located at chain transfer mechanism with grain pressing rod, large quantity space can be saved by underlying for grain pressing rod,
Two chains, one for placing spike of rice, another is for placing the foundation portion of rice straw, determines that rear whole spike of rice can be more steady when transmitting at 2.When rice straw is brought to below chain, by gravity or other briquetting machine effects, the cylinder place fallen to below chain transmission system carries out threshing to the rice straw of fringe side, and the foundation portion of rice straw is also clamped by grain pressing rod, continue to transmit, until the rice straw after threshing is transported to discharging opening.
Further, for press standing grain gap between bar side chain bar and grain pressing rod, between described grain pressing rod and frame, be provided with the elastic component of pressing standing grain gap described in activity adjustment.
Realize the resilient clamp to rice straw by elastic component, the adjustment in the pressure standing grain gap of different feed quantity can be adapted to, there is stronger versatility.
Further, with sprocket on described bar side chain bar, with sprocket or comprise one group of laminated v-belt connected in turn on described fringe side chain bar.
Can with sprocket or the laminated v-belt composition connected in turn primarily of a group on described fringe side chain bar.Wherein fringe side chain bar is more suitable by laminated v-belt group.Come off because spike of rice is easily extruded, in order to avoid spike of rice directly drops on the transfer mechanism (likely cause metal bracelet stuck), the mode that fringe side chain bar can adopt V-belt to connect in turn is shaped, compared with profile of tooth chain, spike of rice can not be subject to rigidity extruding, difficult drop-off, even and if between the crack dropping to V-belt, be also difficult to produce stuck phenomenon.
