One end of the drive shaft is fixedly connected to the center of the seed disk, and the other end is connected to the drive chain. The wheels are fixedly connected, and the middle is supported on the seed suction chamber shell via a bearing.

The combined suction block is composed of a toggle movable piece and a seed sucking piece. The toggle movable piece and the sucking piece are fixedly connected by screws, and the toggle movable piece and the seed sucking piece are arranged on the side of the cylinder in contact with the seed sucker. In a stepped shape, the diameter of the step gradually increases from the middle to the two sides. Two grooves are symmetrically provided on the surface of the moving block on one side of the seed suction chamber. The bottom plane of the groove is parallel to the surface of the moving block and is parallel to the concave surface. One side of the groove is perpendicular to the radial surface, and the included angle with the other side of the radial surface is 100-130°.

The rotation orienting device includes a motor, a rotating arm, a sleeve, a shift lever and a spring. The sleeve, shift lever and spring are arranged in pairs. The motor is located outside the seed suction chamber and fixed on the housing of the seed suction chamber, and the motor shaft passes through The housing of the seed suction chamber extends into the seed suction chamber. The middle of the rotating arm is fixedly connected with the motor shaft along the radial direction of the seed suction disc. The two ends of the rotating arm are respectively fixedly connected to two sleeves vertically, and the lever is a cylindrical shape with a shoulder in the middle. One end of the two shift rods are respectively installed in the two sleeves, the shift rod and the sleeve are in clearance fit, and two springs are respectively housed outside the two sleeves, and the other ends of the two shift rods are in contact with the surface of the movable block.

Its working principle is: an air suction type garlic directional seeding device is installed on the garlic planter, the suction pipe is connected to the fan inlet, and the tractor provides power to drive the transmission sprocket to rotate and the fan to work. The garlic planting in the garlic planting box passes through the seed room. The upper end of the casing enters the seed chamber with a proper amount. The fan works through the suction tube to generate negative pressure in the seed suction chamber. The transmission sprocket drives the seed suction plate to rotate counterclockwise, and the seed suction through hole of the combined suction block on the seed suction plate rotates to the seed suction area. When the garlic seeds in the seed chamber are adsorbed on the suction through holes under the action of negative pressure, the garlic seeds on the suction through holes will continue to rotate with the suction disc to enter the orientation zone. When it passes the directional shrapnel, the directional shrapnel will stand Pour down the garlic seeds so that the garlic seeds lie flat on the seed suction through holes of the seed sucker. When the suction through holes turn over the inner and outer directional needles, the garlic seeds on the through holes are sucked on the inner and outer needles. Under the constraint of the directional needle, pluck off the excess garlic seeds and leave only one, and make the length of the garlic seeds along the direction of movement with the tooth tips facing forward or backward to achieve the first orientation. The garlic after the first orientation When the seeds are transferred to the image collector position with the seed suction plate, the image collector collects garlic seeds images. The garlic seeds images are judged by the image recognition control unit to determine the direction of the garlic seeds. If the garlic seeds are facing forward, the image recognition control unit Send a signal to the motor. When the combined suction block carrying the garlic seeds moves to the position of the rotation orienting device, the motor is started to rotate 180°, and the combined suction block is rotated by the lever to rotate 180° relative to the suction plate, and the garlic seeds also rotate 180° accordingly. °, make the garlic seeds face backward, complete the second orientation, the garlic seeds that enter the seeding area are all backwards, and discharge upright in the seeding area to complete the directional discharge of single garlic seeds. By analogy, the air suction type garlic directional seeding device discharges garlic seeds one by one in a directional direction.

The beneficial effects achieved by the present invention are:

1. The directional shrapnel, inner directional needle and outer directional needle of the present invention realize the singulation and first orientation of garlic seeds. When the garlic seeds reach the image collector for image acquisition and recognition, the tooth tips are only facing forward and backward In both cases, the image recognition processing is simple, fast and accurate.

2. The orientation of the garlic seeds of the present invention is adjusted in two orientations for multiple times, the secondary rotation orienting mechanism is simple to move, and the discharged garlic seeds have a high consistency rate of tooth tips, which can improve the upright planting rate of the garlic planter.

3. The invention adopts the combination of air suction seed collection and image recognition control technology to realize the single-grain directional seeding of garlic seeds. There are no special requirements on the shape and center of gravity distribution of the garlic seeds. It is suitable for single-grain garlic seeds. Directional seeding.
