Automatic and uniform seed placement device and method for rice planting

Abstract

The invention relates to the technical field of rice sowing, and discloses an automatic uniform seed dropping device and method for rice planting. The device and method comprise a shell, wherein a feed port is provided at the top of the shell, a feed trough is provided at the top of the shell, and baffles are slidably connected to the left and right sides of the feed trough. The device and method for automatic uniform seed dropping for rice planting control the switch of the feed trough by the weight of seeds accumulated at the top of a trigger plate, so that seeds are automatically replenished when there are fewer seeds, thereby avoiding a reduction in the sowing rate due to lack of timely replenishment. When too many seeds are accumulated, the feed trough is automatically closed, thereby avoiding a reduction in the speed of seeds passing through the shell due to the accumulation of seeds at the top of the trigger plate. At the same time, when the trigger plate moves, the semi-gear drives the impact block to impact the inner plate, so that the trigger plate vibrates, thereby accelerating the speed of seeds passing through the through hole. Seeds can be sown periodically, and the sowing rate increases with the increase in the rotation speed of the shaft, thereby achieving the effect of equidistant sowing.

[0002] Rice is one of the main grains in my country. When raising rice seedlings, you first need to sow the seeds on the surface of the seedling bed and wait for the seeds to germinate before planting.

The rotating pin is rotatably connected to the inside of the annular groove. The end of the bent rod 22 away from the driving rod 21 is retractable. The end of the bent rod 22 away from the driving rod 21 can drive the slider 23 to move up and down reciprocatingly. The adjusting disk 20 The bottom end is rotatably connected to the output end of the driving rod 21, and the surface of the driving rod 21 is fixedly connected to a bent rod 22. The end of the bent rod 22 away from the driving rod 21 is rotatably connected to a slider 23. Grooves are provided at both upper and lower ends of the surface of the adjusting disk 20.

The other end of the elastic cloth is fixedly connected to the inner wall surface of the adjusting disk 20. The elastic cloth prevents seeds from passing through the groove. The end of the slider 23 away from the bent rod 22 is rotatably connected to a connecting rod 24. The end of the connecting rod 24 away from the slider 23 is rotatably connected to a connecting block 25. There are two connecting blocks 25 on the same side of the adjusting disk 20, and the two connecting blocks 25 are symmetrically installed inside the adjusting disk 20. A shield 26 is fixedly connected to the surface of the connecting block 25. The end of the shield 26 away from the connecting block 25 is fixedly installed on the inner wall surface of the groove provided on the surface of the adjusting disk 20. The width of the shield 26 is equal to the width of the groove. The periodic movement of the shield 26 drives the notch to open and close periodically.

[0044] Support rods 27 are fixedly installed on both sides of the bottom end of the housing 1, and the bottom end of the support rod 27 is rotatably connected to a rotating shaft 28. Rollers 29 are fixedly installed on both ends of the surface of the rotating shaft 28, and a rotating disk 30 is fixedly installed in the middle of the surface of the rotating shaft 28.

[0045] A resistor bar 31 is fixedly installed inside the turntable 30 , a contact 32 is slidably connected to the surface of the resistor bar 31 , a buffer spring 33 is movably connected to the surface of the contact 32 , and a support rod 34 is fixedly installed inside the turntable 30 .

[0046] When in use, the seeds are piled up at the top of the feed port 2. At this time, the feed slot 3 is opened, and the seeds enter the feed slot 3 through the feed port 2, and then enter the top of the trigger disk 7 inside the shell 1. The seeds enter the bottom of the trigger disk 7 through the through hole 8 provided on the surface of the trigger disk 7. Since the speed of the seeds passing through the through hole 8 is slow, more and more seeds are accumulated on the surface of the trigger disk 7. At this time, the mass of the trigger disk 7 continues to increase, and the trigger disk 7 moves downward. When the trigger disk 7 moves downward and compresses the spring rod 18, the trigger disk 7 drives the baffle 4 to contact each other through the push rod 5, thereby closing the feed slot 3. At this time, the seeds inside the feed port 2 cannot pass through the feed slot 3. After the seeds move downward through the trigger disk 7 to complete the sowing, the mass of the seeds accumulated on the surface of the trigger disk 7 is reduced, causing the trigger disk 7 to move on the spring rod 18 moves upward under the action of the restoring force, at this time the trigger disk 7 moves and drives the baffle 4 to move away from each other through the push rod 5, thereby opening the baffle 4, and the seeds inside the feed port 2 enter the shell 1 again, and the trigger disk 7 drives the rotating outer disk 9 to move when moving in the vertical direction, and the semi-gear 11 connected to the inner wall of the outer disk 9 rotates in meshing engagement with the surface of the rack 17, and the semi-gear 11 rotates and drives the fixedly connected rotating rod 12 to rotate, and the rotating rod 12 drives the fixedly connected impact block 13 to rotate and collide with the inner disk 10 to make it vibrate periodically, and the vibration of the inner disk 10 drives the rotatingly connected trigger disk 7 to vibrate, so that the seeds pass through the through hole 8 faster, avoiding the accumulation of seeds and causing blockage at the top of the trigger disk 7, and when the push roller 29 drives the shell 1 to move, the rotating shaft 28 As the roller 29 rotates, the shaft 28 drives the turntable 30 to rotate. The centrifugal force generated by the rotation of the turntable 30 drives the contact 32 to slide on the surface of the resistor bar 31, so that the resistance value of the resistor bar 31 decreases, and the driving rod 21 electrically connected to the resistor bar 31 is driven. The rotation of the driving rod 21 drives the bending rod 22 to rotate. The rotation of the bending rod 22 drives the rotatably connected slider 23 to move up and down reciprocatingly in the vertical direction. When the slider 23 moves, the rotatably connected connecting block 25 is driven to move up and down reciprocatingly through the connecting rod 24. When the connecting block 25 moves, it drives the fixedly connected shield 26 to move telescopically, thereby driving the notch on the surface of the adjusting disk 20 to open periodically, so that the seeds fall from the shell 1 periodically and are sown, and the frequency of the opening of the notch of the adjusting disk 20 is directly proportional to the rotation speed of the shaft 28, so as to achieve the effect of completing sowing at a specified distance.

[0047] In summary, the automatic uniform seed placement device and method for rice planting controls the switch of the feed trough 3 by the weight of the seeds accumulated on the top of the trigger disk 7, so that the seeds are automatically replenished when there are fewer, avoiding the reduction of the sowing rate due to the lack of timely replenishment. When the seeds are accumulated too much on the surface of the trigger disk 7, the feed trough 3 is automatically closed to avoid the excessive accumulation of seeds on the top of the trigger disk 7, which leads to a reduction in the speed of the seeds passing through the shell 1. At the same time, the half gear 11 drives the impact block 13 to impact the inner disk 10 when the trigger disk 7 moves, so that the trigger disk 7 vibrates, thereby accelerating the rate at which the seeds pass through the through hole 8. When the shell 1 moves with the rotation of the rotating shaft 28, the rotating disk 30 rotates accordingly, so that the driving rod 21 electrically connected to the resistor bar 31 drives the shutter 26 to open and close periodically, so that the seeds are sown periodically, and the sowing rate increases with the increase of the rotation speed of the rotating shaft 28, thereby achieving the effect of equidistant sowing.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
