To wheeled clear shutoff air suction drum-type seed metering ware, cylinder (6) are fixed through the bolt with end cover (1), sealed lid (2) are fixed as an organic wholely through screw and end cover (1), sprocket (5) pass through bolt rigid connection with sealed lid (2), cooperation through first bearing (4) and separate pressure axle (3), separate pressure axle (3) fixed, sprocket (5) rotation drive cylinder (6) synchronous rotation, cylinder (6) surface inhale the hole adoption staggered arrangement mode, clear stifled device is fixed in separate pressure axle (3) through the bolt by clear stifled upper bracket (7), separate pressure axle (3) right-hand member and fan link to each other, shaft shoulder department is connected with cylinder rotation part through first bearing (4), separate pressure axle (3) are as an organic whole by hollow shaft and two pressure-isolating plates welding, two pressure-isolating plates separate the inside air chamber of cylinder, be negative pressure air chamber and ordinary pressure air chamber respectively.
To clear stifled cylinder seed metering ware of blocking up air, clear stifled upper bracket (7) are fixed in on separate pressure axle (3) through the bolt, clear stifled lower carriage (9) is connected by spring (8) with clear stifled upper bracket (7), long axis (10) are installed on clear stifled lower carriage (9), clear stifled gyro wheel (11) are through second bearing (12) and long axis (10) cooperation, interference fit is all adopted to the outer lane in second bearing (12), ensure that clear stifled gyro wheel (11) position can not take place the skew, and cylinder (6) rotate drive clear stifled gyro wheel (11) rotate, realize the effect of clear suction hole jam thing.
The roller suction holes of the roller type blocking-removing air suction roller type seed metering device are arranged in a staggered mode.
For the roller type blocking-clearing air-sucking roller-type seed metering device, blocking-clearing teeth are arranged on the circumferential surface of the blocking-clearing roller (11), the blocking-clearing teeth are matched with roller suction holes, the blocking-clearing teeth are arranged in a staggered mode, and the blocking-clearing roller (11) rotates along with the rotation when the roller (6) rotates.

Detailed Description
The invention is described in further detail below with reference to the drawings and the detailed description.
As shown in fig. 1, the roller (6) is fixed with the end cover (1) through bolts, the sealing cover (2) is fixed with the end cover (1) through bolts into a whole, the chain wheel (5) is rigidly connected with the sealing cover (2) through bolts, the roller (6), the end cover (1), the sealing cover (2) and the chain wheel (5) form a whole together, the roller (6), the end cover (1), the sealing cover (2) and the chain wheel (5) are matched with the fixed pressure-isolating shaft (3) through the first bearing (4), and the rotary motion is formed through transmission of the chain wheel (5).
As mentioned before, the pressure isolating shaft (3) is formed by welding a hollow shaft and two pressure isolating plates, the two pressure isolating plates isolate the air chamber inside the roller and are respectively a negative pressure air chamber and a normal pressure air chamber, when the roller absorbs Kong Zhuairu the negative pressure air chamber, seeds are adsorbed and rotate along with the roller (6), when the seeds rotate to the pressure isolating surface, the negative pressure disappears, the seeds fall into the seed feeder, and the power consumption of a matched fan can be reduced by reducing the size of the negative pressure air chamber.
As mentioned above, when seeds fall into the seed feeder, part of impurities or broken seeds can block the suction holes, and the suction holes are turned to the blockage removing device. The anti-blocking upper bracket (7) is fixed on the pressure isolating shaft (3) through bolts, the anti-blocking lower bracket (9) is connected with the anti-blocking upper bracket (7) through a spring (8), the long shaft (10) is arranged on the anti-blocking lower bracket (9), the anti-blocking roller (11) is matched with the long shaft (10) through a second bearing (12), the inner ring and the outer ring of the second bearing (12) are in interference fit, the position of the anti-blocking roller (11) is ensured not to deviate, and the roller (6) rotates to drive the anti-blocking roller (11) to rotate, so that the effect of removing blocking objects of a suction hole is realized.
As described above, the suction holes of the drum are arranged in a staggered manner, and compared with the single-row arrangement, the staggered arrangement has more seeds when the rotation speed of the drum is the same. When the sowing interval is required to be unchanged, the operation speed can be greatly improved.
As mentioned before, the circumferential surface of the block-cleaning roller (11) is provided with block-cleaning teeth, the block-cleaning teeth are matched with the suction holes of the roller, the block-cleaning teeth are arranged in a staggered mode, and when the roller (6) rotates, the seed-cleaning roller (11) rotates along with the seed-cleaning roller, so that the block-cleaning effect is achieved.
