[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment 1:

[0024] like Figures 1 to 4 As shown, the single seed taking mechanism of the garlic planter of the present invention includes three seed taking driven shafts 1 and one seed taking driving shaft 5, at least one sprocket or pulley A2 is provided on the seed taking driven shaft 1, at least one sprocket or pulley B6 is provided on the seed taking driving shaft 5, and there are four sprockets or pulleys A2 and four sprockets or pulleys B6 as shown in the figure. The sprocket or pulley A2 is connected with the corresponding sprocket or pulley B6 through a chain or synchronous belt A3, and a plurality of evenly distributed supporting plates 4 are fixed on the chain or synchronous belt A3, and the seed taking driven shaft 1 and the seed taking driving shaft 5 are rotated in the positive direction through the driving mechanism; wherein, the rotation direction of the driving mechanism is set to be the positive direction. The present invention also includes a garlic sowing mechanism, which includes a first garlic sowing shaft 26, and a flexible garlic sowing plate 30 corresponding to the position of the chain or synchronous belt A3 is provided on the first garlic sowing shaft 26, and the first garlic sowing shaft 26 is rotated in the opposite direction through the driving mechanism and the changing mechanism.

[0025] Specifically, the driving mechanism in this embodiment includes an intermediate transition shaft 8, a sprocket or pulley D9, a sprocket or pulley E10, a sprocket or pulley F12, a chain or synchronous belt C13, a sprocket or pulley G14, and a ground wheel 15. The sprocket or pulley G14 is fixedly connected to the central axis of the ground wheel 15, the sprocket or pulley D9, the sprocket or pulley E10 and the sprocket or pulley F12 are fixed on the intermediate transition shaft 8, the sprocket or pulley D9 is connected to the sprocket or pulley G14 through the chain or synchronous belt C13, and the sprocket or pulley F12 is connected to the sprocket or pulley C7 on the seed taking drive shaft 5 through the chain or synchronous belt B11.

[0026] Specifically, the direction-changing mechanism in this embodiment includes a first direction-changing shaft 18, a second direction-changing shaft 19, a first gear 20, a second gear 21, a sprocket or pulley I22, and a sprocket or pulley J23. The sprocket or pulley I22 and the first gear 20 are fixedly arranged on the first direction-changing shaft 18, and the second gear 21 and the sprocket or pulley J23 are fixedly arranged on the second direction-changing shaft. The sprocket or pulley I22 is connected to the sprocket or pulley H16 via a chain or synchronous belt D17. The first gear 20 and the second gear 21 are meshedly connected, and the sprocket or pulley J is connected to the sprocket or pulley K25 on the first garlic shaft 26 via a chain or synchronous belt E24.

[0027] Specifically, the driving mechanism of the present invention is also connected to the planting drive shaft 35, and the planting drive shaft 35 is provided with a sprocket or pulley O36, and the sprocket or pulley O36 is connected to the sprocket or pulley E10 through a chain or synchronous belt G37. The planting drive shaft 35 is used to drive the planting mechanism of the planter to plant garlic seeds into the soil.

[0028] The working process of this embodiment is as follows: the ground wheel 15 moves in the field under the traction of the agricultural machine to generate driving force, driving the chain or synchronous belt A3 and the supporting plate 4 on the seed taking mechanism to rotate counterclockwise, and the garlic seeds in the garlic seed box 44 fall on the supporting plate 4 through the discharge port. At this time, each supporting plate 4 may have one or more garlic seeds, and the garlic seeds rise counterclockwise following the chain or synchronous belt; at the same time, the ground wheel 15 drives the first garlic-peeling shaft 26 to rotate clockwise through the changing mechanism. When there is only one garlic seed on the supporting plate 4, the flexible garlic-peeling plate 30 on the garlic-peeling mechanism cannot touch the garlic seed during the rotation process or can only touch it slightly but cannot remove the garlic seed. When there are multiple garlic seeds on the supporting plate 4, the flexible garlic-peeling plate 30 can touch it slightly to remove the excess garlic seeds on the supporting plate 4 of the seed taking mechanism, thereby ensuring that there is only one garlic seed on each supporting plate 4 of the seed taking mechanism, so that the garlic seeder meets the agronomic requirements of garlic sowing. When the pallet 4 turns to move downward, the chain or synchronous belt A3 and the box plates on both sides and the front end of the pallet 4 form a closed space, and the garlic seeds fall on the other pallet 4 at the front end under the action of gravity and continue to move downward. When the pallet 4 turns to move horizontally again, the garlic seeds are no longer supported by the pallet and fall into the planting mechanism under the action of gravity.

[0029] Embodiment 2:

[0030] In order to improve the success rate of the garlic-planting mechanism in removing excess garlic seeds, the garlic-planting mechanism also includes a second garlic-planting shaft 29 arranged in parallel with the first garlic-planting shaft 26, a flexible garlic-planting plate 30 corresponding to the chain or synchronous belt A3 position is arranged on the second garlic-planting shaft 29, a sprocket or pulley L27 is fixedly arranged on the first garlic-planting shaft 26, and a sprocket or pulley M28 is fixedly arranged on the second garlic-planting shaft 29, and the sprocket or pulley L27 is connected to the sprocket or pulley M28 through a chain or synchronous belt F31. The first garlic-planting shaft 26 and the second garlic-planting shaft 29 simultaneously drive the flexible garlic-planting plate 30 to rotate and remove excess garlic seeds, which greatly improves the success rate of removing excess garlic seeds.

[0031] The other contents of this embodiment are the same as those of Embodiment 1.

[0032] Embodiment 3:

[0033] This embodiment also includes a seesaw drive shaft 33, a movable seesaw 41 and a guide protrusion 43. The seesaw drive shaft 33 is provided with a sprocket or pulley N32 and a triangular plate 34. The sprocket or pulley N32 is connected to the sprocket or pulley J23 and the sprocket or pulley K25 through a chain or synchronous belt E24. The movable seesaw 41 and the guide protrusion 43 are arranged at intervals at the bottom of the garlic seed box 44, and the triangular plate 34 is arranged at the bottom of the movable seesaw 41. In the process of driving the triangular plate 34 to rotate, the seesaw drive shaft 33 intermittently pries the movable seesaw 40 covering the discharge port, so that each time the movable seesaw 40 moves up and down, garlic seeds will fall onto the support plate 4 through the discharge port.

[0034] like Figure 5 , Figure 6 As shown, the present embodiment also includes a garlic seed leakage prevention device, which includes a frame 45 and at least one garlic seed leakage nozzle 46. The number of garlic seed leakage nozzles 46 corresponds to the number of chains or synchronous belts A3. The garlic seed leakage nozzle 46 includes two side baffles 47, a top baffle 48 and a movable tongue 49. The two side baffles 47 are vertically fixedly connected to the frame 45 in parallel to form a channel. The top baffle 48 is fixed to the upper part between the two side baffles 47. The cross-section of the movable tongue 49 is a reverse "7" shape, and its bottom is movably connected to the side baffle 47 through a pin 50.

[0035] The support plate 4 passing through the garlic seed leakage nozzle 46 moves upward along with the chain or synchronous belt A3 and moves to the bottom of the garlic seed leakage nozzle. The movable tongue 49 tilts outward under the action of gravity, blocking the gap between the chain or synchronous belt or the synchronous belt A3 and the garlic seed leakage nozzle 46 to prevent the garlic seeds from leaking out. The garlic seeds fall into the top of the movable tongue 49 in the garlic seed leakage nozzle 46, and the support plate 7 continues to move upward along with the chain or synchronous belt A3 to push the movable tongue 49 toward the inside of the garlic seed leakage nozzle 46. The garlic seeds fall onto the support plate 4 under the blockage of the top baffle 47, and the process is repeated in sequence. Each support plate 4 passing through the garlic seed leakage nozzle falls into the garlic seeds after the above process.

[0036] like Figure 7 , Figure 8 As shown, in this embodiment, a limit plate 42 is provided in the garlic seed box 44, and the limit plate 42 includes an upper plate 51 and a lower plate 52. The upper plate 51 is provided with an adjustment long hole 53, and the lower plate 52 is connected to the adjustment long hole 53 by a bolt 54. By adjusting the fixed position of the lower plate 52 in the adjustment long hole 66, the gap between the bottom of the lower plate 52 and the bottom of the garlic seed box 44 can be adjusted, thereby adjusting the amount of leaked garlic.
