The photoelectric sensor 8 is arranged on the baffle plate to detect the in-position state of the garlic seeds;

The rotating motor 10 is arranged on the bracket 1 and is connected with the turning tray 12, and is used to drive the turning tray 12 to turn over;

The proximity switches 9 are arranged on the side of the bracket 1 where the rotating motor 10 is installed and are placed at both ends of the inversion tray 12 to detect the in-position state after the inversion tray 12 is rotated.

In this embodiment, the conveying member is the conveying square pipe 7, and the straightening conveying mechanism and the direction adjusting mechanism are set obliquely. The cross-sectional dimension of the square tube 7 is smaller than the length L of the garlic seed and greater than the width H of the garlic seed.

In this embodiment, the detection mechanism 6 includes a set of opposite light gratings, and is vertically arranged on the straightening and conveying mechanism.

(1) Recognition of the direction of garlic scale buds:

a. The conveyor belt transports garlic seeds through the grating area, and the photoelectric signal sampling period T must be greater than the time t for the garlic seeds to pass through the grating area, t=L/v, L is the length of the garlic seeds, and this value is the average value obtained by sampling and measurement; v is the speed of the conveyor belt, obtained by measuring the speed of the conveyor motor 2;

Garlic garlic is mainly composed of three surfaces, and there are three states during the conveying process, as shown in Figure 1, state 1: surface II is the bottom surface in contact with the conveyor belt; state 2: surface III is the bottom surface in contact with the conveyor belt; state 3: surface Ⅰ is the contact between the bottom surface and the conveyor belt. The garlic and garlic seeds pass into the grating area, and the photoelectric signal is triggered from the garlic seeds entering the grating area to the garlic seeds leaving the grating area. The garlic and garlic seeds on the straightening and conveying mechanism pass through the detection mechanism. Signal generation array, the number of arrays is denoted as N, and the arrays of the two intervals (0, 0.3N) and (0.7N, N) are extracted, which is equivalent to extracting the front 30% and the rear 30% along the length of the garlic. Contour data, through integral operation, the contour area S1 of the front 30% part and the contour area S2 of the rear 30% part along the garlic length L direction are obtained. When S1>S2, the rear part is the garlic scale bud, and when S2 >S1, the front part is the garlic scale bud;

(2) Adjustment of the direction of garlic scales:

According to the identification result of the garlic scale bud direction, when the scale bud direction is at the front end of the running direction, the turning tray 12 is turned to the rear end; when the scale bud direction is at the rear end of the running direction, the turning tray 12 is turned to the front end; After the angle, the garlic seeds slide into the mouth of the seed dropping tube 11. After the inversion operation is completed, the proximity switch 12 detects whether the inversion tray 12 is in a horizontal state.

The photoelectric sensors 8 are arranged on the baffles on both sides of the inversion tray 12. The length of the detection area is greater than the length L of the garlic seeds. The garlic seeds are in the photoelectric detection area after sliding into the inversion tray 12, as shown in Figure 3. trigger. If the garlic seed triggers the photoelectric sensor on the far right, no matter whether the garlic seed is in a static state or a sliding state at this time, in order to prevent the garlic seed from sliding out of the turning tray 12 to the right, the rotating motor 10 will act immediately. Partly, the overturning tray 12 is turned over to the rear end to prevent the garlic seed from continuing to slide, and the garlic seed is slid into the nozzle on the left side of the seed drop tube 11; 2. the rear end of the operation is the scale bud part, and the overturning tray 12 is turned over to the front end to promote the garlic seed to continue. Slide, slide the garlic seeds into the right nozzle of the seed drop tube 11.

The device of the present invention also has the function of adjusting the spacing of garlic seeds, and the specific method is:

Adjust the speed of the conveying motor 2 and the rotation of the rotating motor 10, so that the conveying action and the speed of the turning action are coordinated, the speed v of the conveying belt changes, and the distance between the garlic seeds that fall on the conveying belt in an orderly manner also changes, v becomes garlic The distance between the seeds increases, v becomes smaller and the distance between the garlic seeds decreases, and the time interval between the garlic seeds that are flipped and slid into the seed pipe 11 through the inversion tray 12 also changes with the change of v, and finally passes through. The distance between the garlic seeds sown in the soil by the seeding device also changes with the change of v, so as to realize the purpose of adjusting the spacing between garlic seeds.

Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
