Specific embodiment
As shown in Figure 1 to Figure 3, a kind of cylinder concave with antiwind anti-blockage function of the invention sieves formula threshing system
System, it is similar with conventional cylinder concave sieve formula threshing system, include rack, is on the rack equipped with and to be distributed in the horizontal direction
Threshing cylinder 5 and driving device for driving high-speed rotation of the drum are equipped with arc positioned at the upper edge of threshing cylinder 5 on the rack
Cover board 1 is equipped with grid concave plate sieve 15 positioned at the lower edge of threshing cylinder 5 on the rack, passes through the spike-tooth 4 and grid being distributed on roller
Strike between lattice concave grate 15 curries effect and carries out threshing.
Unlike conventional cylinder concave sieve formula threshing system, the invention also includes for adjusting grid concave plate sieve 15
The anti-blocking mechanism in gap and broken de- to be discharged for cutting the stalk being wrapped on threshing cylinder 5 between threshing cylinder 5
The winding-preventing mechanism of grain system.
Anti-blocking mechanism is as shown in Figure 1, include being distributed on the rack and being located at 15 left side of grid concave plate sieve along the vertical direction
Shaft 10 and fixing axle 12.The upper end of shaft 10 is coaxially fixed with cylindrical cam 6, and the lower end surface of cylindrical cam 6 is set as
Figure wheel face, the lower end of shaft 10 are equipped with the motor 11 for driving cylindrical cam 6 to rotate, and motor 11 is fixedly connected on the machine of being distributed in
On 11, motor on frame.The middle part of fixing axle 12 is fixed with seat board 13, and the top of fixing axle 12 is equipped with supporting block 8, is propping up
The slide opening being slidably matched with fixing axle 12 is offered on bracer 8, is arranged between supporting block 8 and seat board 13 in fixing axle 12
There is spring 9, the both ends of spring 9 are fixedly connected with supporting block 8 and seat board 13 respectively.At the top of supporting block 8 close to cylindrical cam 6
The position of side is equipped with boss 7, and the upper edge of boss 7 is engaged with the cam lower edge of cylindrical cam 6 and spring 9 is made to be in compression
State controls lifting of the supporting block 8 in fixing axle 12 by the thrust of spring 9 and the rotating housing of cylindrical cam 6.Supporting block
8 sides for sieving 15 with grid concave plate are articulated and connected, and the other side articulated connection of grid concave plate sieve 15 is on the rack.
In the present embodiment, as shown in Figure 1, being equipped with the axis hole being distributed in the horizontal direction, axis hole transfer on the right side of supporting block 8
