Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. An automatic seed cleaning, blockage preventing and seeding rate adjustable air suction pocket type roller seed sowing device comprises an air suction pocket type roller 1, a plurality of pocket holes 2 are formed in the wall of the air suction pocket type roller 1 along the radial direction, a seed box 3, a seed cleaning brush 4 and a seed protecting belt 5 are sequentially arranged and installed at the upper position of the outer side of the wall of the air suction pocket type roller 1 along the clockwise direction of the circumference, a barrel type seed filling cup 6 is fixedly installed in each pocket hole 2, the barrel type seed filling cup 6 is communicated with the seed box 3, a suction nozzle body 7 is installed in each cup hole of the barrel type seed filling cup 6 in a threaded connection mode and can axially move, an air suction hole 7-3 and a hollow cavity 7-2 which are coaxial along the axial direction and are communicated with each other are sequentially formed in the suction nozzle body 7, two ends of the air suction hole 7-3 are respectively communicated with the barrel type seed filling cup 6 and the hollow cavity 7-2, a cross-shaped groove 7-4 is formed in the end face, located on one side of the air suction hole 7-3, of the suction nozzle body 7, a limiting stop pin 10 is inserted on one side of a hollow cavity 7-2 of a suction nozzle body 7, a gravity rod 9 which is coaxially and fixedly provided with a seed cleaning anti-blocking needle 8 can be axially and reciprocally inserted into the hollow cavity 7-2 of the suction nozzle body 7, the seed cleaning anti-blocking needle 8 is in insertion and closed fit or in separation and insertion fit with a suction hole 7-3 in the suction nozzle body 7, the gravity rod 9 is in contact and limited fit or in separation and contact fit with the limiting stop pin 10, a through hole 7-1 is formed in the side wall of the suction nozzle body 7, and the hollow socket cavity 7-2 of the suction nozzle body 7 is communicated with the inner cavity of the air suction eye type roller 1 through the through hole 7-1.
When the negative pressure air suction pocket type roller is used, the inner cavity of the air suction pocket type roller 1 is communicated with a negative pressure air source in a sealing mode, so that the inner cavity of the air suction pocket type roller 1 becomes a negative pressure air chamber. When the pneumatic suction pocket type roller 1 is driven to rotate clockwise by external power transmission (see attached drawing 2 of the specification) during operation, when the suction nozzle body 1 rotates to a position above the axial lead of the pneumatic suction pocket type roller 1 along with rotation, under the action of gravity, the gravity rod 9 drives the seed cleaning anti-blocking needle 8 to move downwards along the axial direction in the hollow cavity 7-2 of the suction nozzle body 7 together, so that the seed cleaning anti-blocking needle 8 is separated from the insertion fit with the air suction hole 7-3 on the suction nozzle body 7, the negative pressure suction force in the cylinder cavity of the pneumatic suction pocket type roller 1 sucks seeds in the cylinder 3 into the cup cavity of the cylinder type seed filling cup 6 through the through hole 7-1, the hollow cavity 7-2 and the air suction hole 7-3 in sequence, and the gravity rod 9 is in contact with the limit stop pin 10 for limiting at the moment; the continuously rotating air suction pocket type roller 1 drives the cylinder type seed filling cup 6 which has sucked seeds to complete the operations of cleaning seeds outside the cup cavity of the cylinder type seed filling cup 6 and carrying seeds for transportation and rotation under the coordination with the seed cleaning brush 4 and the seed protecting belt 5, and the cleaned seeds fall back into the seed box 3; when the cylindrical seed-filling cup 6 after seed cleaning is rotated to the lower part of the axial lead of the air-suction pocket type roller 1, under the action of gravity, the gravity rod 9 drives the seed cleaning anti-blocking needle 8 to move downwards along the axial direction in the hollow cavity 7-2 of the suction nozzle body 7, the gravity rod 9 is separated from the contact fit with the limit stop pin 10, the gravity rod 9 closes the through hole 7-1 on the side wall of the suction nozzle body 7, the communication between the negative pressure inner cavity of the air suction pocket type roller 1 and the air suction hole 7-3 on the suction nozzle body 7 is cut off, so that the negative pressure suction force in the air suction hole 7-3 disappears, and seeds sucked and positioned in the cup opening of the cylinder type seed filling cup 6 fall down by the self gravity to finish seed sowing, synchronously, the seed cleaning anti-blocking needle 8 is inserted into the air suction hole 7-3 on the suction nozzle body 7, and the front end of the seed cleaning anti-blocking needle extends out, so that the blockage cleaning and dredging and auxiliary forced seeding operation on the air suction hole 7-3 are completed; the continuous operation of air suction seed filling, seed cleaning, seed protection, seed discharging and blocking prevention is performed in sequence and circularly.
When the seeding amount is adjusted, the rotation of the air suction pocket type roller 1 is stopped, a linear or cross-shaped tool is inserted into the cross-shaped groove 7-4 clamped on the end face of the suction nozzle body 7 to drive the suction nozzle body 7 to rotate, the suction nozzle body 7 moves axially in the cylindrical seed filling cup 6 under the control of thread fit, the volume of the outer end hole of the seed filling cavity in the cylindrical seed filling cup 6 is adjusted and changed, and the seeding amount is adjusted.
