[0024] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0025] Such as Figure 1-3 As shown, the automatic garlic planting machine of the present invention includes a frame 17, a seed box 1 and a seed meter 3 are fixed on the upper part of the frame 17, and the outlet of the seed box 1 corresponds to the entrance of the seed meter 3, and is characterized in : The seed metering outlet 4 of the seed metering device 3 corresponds to the upper directional bucket 6 set below the seed metering device 3, and the lower directional bucket 7 is correspondingly set below the upper directional bucket 6, and the corresponding upper directional bucket 6 and the lower directional bucket 7 The directional bucket opening device 19 and the directional bucket opening transmission device 18 are arranged at the rear. The directional bucket opening device 19 is engaged with the directional bucket opening transmission device 18 through gears, and the directional bucket opening transmission device 18 is connected to the intermediate transmission shaft 20 through a sleeve roller chain. , The intermediate drive shaft 20 is respectively connected to the ground wheel shaft 15, the turntable shaft 11 and the seed metering shaft 2 through a sleeve roller chain, a receiving hopper 8 is correspondingly provided under the lower directional hopper 7, and the vertical seeding turntable 10 is fixed below the receiving hopper 8 The outlet of the hopper 8 corresponds to the duckbill 12 set on the direct seeding carousel 10. A plurality of duckbills 12 are arranged on the direct seeding carousel 10 evenly distributed along the circumference, and a duckbill 12 is arranged under the direct seeding carousel 10 The matching duckbill at the opening opens the cam 13, the frame 17 is connected to the ground wheel 14 through the ground wheel support frame 9, the back of the frame 17 is provided with a pinch wheel 16, and a pinch wheel spring 25 is provided between the pinch wheel 16 and the frame 17 , The leveling device 26 is arranged under the front of the frame, and the leveling device is equipped with a height adjustment device relative to the frame. The frame 17 is provided with a suspension frame 5, and the suspension frame 5 includes an upper suspension frame and a lower suspension frame fixed at the front end of the frame 17 Suspension frame.

[0026] The soil leveling device is composed of two screw conveying devices with opposite rotation directions, which are driven and rotated by the power output shaft of the tractor to transport the soil in the middle to both sides. When the machine moves forward, the ground that the soil leveling device passes through is leveled. It is fixed at a suitable position on the frame, and its shaft is connected with the power output shaft of the tractor with a coupling and a transmission shaft.

[0027] Such as Figure 4 As shown, the directional bucket opening device 19 includes an upper directional bucket opening cam 21 and a lower directional bucket opening cam 22. The upper directional bucket opening cam 21 and the lower directional bucket opening cam 22 are respectively associated with the upper directional bucket 6 and the lower directional bucket 7 Corresponding. The upper directional bucket 6 and the lower directional bucket 7 both include a left half directional bucket 23 and a right half directional bucket 24. The left half directional bucket 23 and the right half directional bucket 24 have the same structure and are symmetrically hinged.

[0028] The upper directional bucket opening cam 21 and the lower directional bucket opening cam 22 are coaxially fixed, and the upper directional bucket opening cam 21 and the lower directional bucket opening cam 22 are provided with a plurality of gear teeth. The gear teeth are preferably evenly distributed on the circumference.

[0029] The gear teeth of the upper directional bucket opening cam 21 and the lower directional bucket opening cam 22 are staggered and fixed by 5-20° in sequence.

[0030] The working principle and use process of the present invention:

[0031] When the present invention is in use, the automatic garlic planting machine is connected to the tractor through the suspension frame 5, and an appropriate amount of garlic seeds are placed in the seed box 1. When working, the ground wheel 14 touches the ground, the leveling device 26 touches the ground, the automatic garlic planter is hauled forward by the tractor, the ground wheel 14 rotates, the ground wheel shaft 15 of the ground wheel 14 drives the intermediate drive shaft 20 to move, and then passes through the middle The transmission shaft 20 drives the turntable shaft 11 and the seed metering device shaft 2 to move, that is, drives the vertical seeding turntable 10 and the seed metering device 3 to rotate. The seed meter 3 continuously picks seeds from the seed box 1 during the continuous rotation, and discharges them into the upper directional bucket 6 below the seed outlet 4 through the seed outlet 4, and the garlic seeds stay in the upper directional bucket 6 After 0.1-1 second, the upper directional bucket 6 is opened symmetrically by the upper directional bucket opening cam 21, and the garlic seeds fall into the lower directional bucket 7. After the garlic seeds stay in the lower directional bucket 7 for 0.1-1 second, the lower directional bucket 7 is removed from the bottom The directional bucket opening cam 22 opens symmetrically, and the garlic seeds fall into the receiving hopper 8. The shape of the upper directional bucket 6 and the lower directional bucket 7 orients the garlic seeds twice, so that the garlic seeds fall into the receiving hopper 8 With the tip of the teeth facing upwards, the mouth of the duckbill 12 on the vertical seeding carousel 10 is always upward when it rotates with the standing seeding carousel 10. When the duckbill 12 rotates to just below the receiving hopper 8, the receiving hopper 8 opens and the receiving hopper 8 The garlic seeds fall into the duck's bill 12, and the duck's bill 12 rotates to reach the bottom of the direct seeding turntable 10, enters the soil and opens under the action of the duck bill opening cam 13, and the garlic seeds are planted upright in the soil.

[0032] The invention has simple structure and reasonable design, can realize garlic planting upright with the tooth tip upward, does not require direct participation in the planting process, realizes mechanical automatic planting of garlic, reduces the labor intensity of workers, and can improve the efficiency of the planting machine. By adjusting the orientation twice, it has a better orientation effect and increased the vertical planting rate.

[0033] The present invention is not limited to the above-mentioned specific embodiments, and changes, modifications, additions or substitutions made by persons of ordinary skill in the art within the essential scope of the present should also fall within the scope of protection of the present invention.
