[0002] During tobacco cultivation, uniform seed sowing is one of the key factors affecting tobacco growth quality and yield. Traditional tobacco sowing methods mainly rely on manual or simple mechanical devices, which have problems such as uneven sowing, seed waste, and high labor intensity. Manual sowing makes it difficult to accurately control the spacing and number of seeds, which can easily lead to seed accumulation or missed sowing, thereby affecting the growth space and nutrient distribution of tobacco plants. Although existing mechanical sowing devices have improved sowing efficiency to a certain extent, they still have shortcomings in seed quantitative distribution and anti-blocking, especially for the sowing of small-particle seeds such as tobacco, which are prone to poor transportation or blockage, resulting in interruptions or uneven distribution during the sowing process.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figures 1-6 As shown, an anti-clogging intermittent tobacco sowing device includes a vehicle body 1, which is provided with a sowing box body 2. The top and bottom of the sowing box body 2 are respectively connected to a seed feed hopper 3 and a seed outlet 4. A delivery pipe 5 connected to the seed feed hopper 3 and a seed equalizing component 6 are provided in the sowing box body 2. The seed equalizing component is used to make the seeds in the delivery pipe 5 fall into the seed outlet 4 intermittently. The delivery pipe 5 is also provided with a vibration component 7 for making the delivery pipe 5 vibrate intermittently to prevent seed clogging.

[0021] like Figure 5 、 Figure 6 As shown, the seed equalization component 6 includes a fixed disk 601, a rotating disk 602 and a motor 603. The top of the motor 603 is fixedly connected to the top inside the box. The output shaft of the motor 603 passes through the fixed disk 601 and is rotatably connected to the fixed disk 601. The end of the output shaft of the motor 603 is fixedly connected to the top center of the rotating disk 602. The rotating disk 602 is located at the bottom of the fixed disk 601, and a gap is set between the top of the rotating disk 602 and the bottom of the fixed disk 601, and the gap is smaller than the size of the seed.

[0022] Specifically, the output shaft of motor 603 rotates, driving rotating disk 602. When through-hole 1 6011 and through-hole 2 6021 align, tobacco seeds in through-hole 1 6011 fall into feed hopper 8 and continue to fall out of seed outlet 4, allowing the tobacco seeds to be sown in the soil. As the output shaft of motor 603 continues to rotate, through-hole 1 6011 and through-hole 2 6021 become out of alignment, and tobacco seeds in feed pipe 5 fall into through-hole 1 6011 on fixed disk 601, awaiting delivery to feed hopper 8.

[0023] Specifically, the motor 603 is a stepping motor, which can control the rotation angle of the output shaft of the motor 603 , thereby controlling the alignment time of the through hole 1 6011 and the through hole 2 6021 .

[0024] like Figure 2 、 Figure 3 、 Figure 4 As shown, a shifting piece 604 is fixedly connected to the output shaft of the motor 603, and the shifting piece 604 is in the shape of an elongated strip.

[0025] Specifically, while the output shaft of the motor 603 drives the rotating disk 602 to rotate, the output shaft of the motor 603 also drives the paddle plate 604 to rotate. After the paddle plate 604 rotates to a certain position, it will hit the ball 705. The ball 705 will move under the action of the spring 2 704, thereby causing the feed pipe 5 to shake, thereby facilitating the seeds in the feed pipe 5 to move downward into the through hole 1 6011.

[0026] Specifically, the second spring 704 is a hard spring, which has a certain supporting effect on the ball 705.

[0027] The fixed disk 601 is provided with a through hole 1 6011 , which is close to the edge of the fixed disk 601 . The rotating disk 602 is provided with a through hole 2 6021 , which is close to the edge of the rotating disk 602 . The positions and specifications of the through holes 1 6011 and 6021 match.

[0028] In this embodiment, the top and bottom of the feed pipe 5 in the sowing box body 2 are fixedly connected with a folding short tube 9. One folding short tube 9 is connected to the seed feed hopper 3 through the seed feed port of the sowing box body 2, and the other folding short tube 9 is connected to the through hole 6011 of the fixed plate 601.

[0029] Specifically, the length of the folded short tube 9 is 1 cm, which can ensure the transportation of tobacco seeds while avoiding interference with the vibration of the feeding pipe 5, thereby ensuring the normal operation of the feeding pipe 5.

[0030] like Figure 2 、 Figure 3 、 Figure 4 As shown, the vibration component 7 includes a bracket 701, a ring 702, a spring 1 703, a spring 2 704 and a sphere 705. Both ends of the side of the ring 702 are fixedly connected to one end of the bracket 701, and the other end of the bracket 701 is fixedly connected to the inner wall of the sowing box 2; the interior of the ring 702 is embedded with a feed pipe 5, and the inner side of the ring 702 is evenly arranged with multiple springs 1 703 in a circumferential direction, one end of the spring 1 703 is fixedly connected to the inner side of the ring 702, and the other end of the spring 1 703 is fixedly connected to the outer wall of the feed pipe 5.

[0031] Specifically, four springs 1 703 are evenly arranged between the ring 702 and the feed pipe 5. The function of springs 1 703 is to provide a buffering force for the feed pipe 5. Springs 1 703 are hard springs that can provide a certain degree of support for the feed pipe 5, ensuring that after the toggle piece 604 stops striking the ball 705, the feed pipe 5 returns to its original position, thereby ensuring that the next striking action can proceed normally.

[0032] One end of the second spring 704 is also fixedly connected to the outer wall of the feeding pipe 5 , and the other end of the second spring 704 is fixedly connected to a sphere 705 , and the sphere 705 and the second spring 704 face the output shaft of the motor 603 .

[0033] The horizontal center line of the toggle piece 604 and the horizontal center line of the sphere 705 are located on the same horizontal plane, and the length of the toggle piece 604 is adapted to the position of the sphere 705, thereby ensuring that the toggle piece 604 can hit the sphere 705, thereby causing the conveying pipe 5 to shake normally.

[0034] A feed hopper 8 is provided at the bottom of the rotating disk 602. The feed hopper 8 is fixedly connected to the inside of the sowing box 2, and the bottom of the feed hopper 8 is connected to the seed outlet 4. There is a gap between the top of the feed hopper 8 and the bottom of the rotating disk 602, and the gap is smaller than the size of the seed.

[0035] Specifically, the gap is smaller than the size of the seeds, thereby ensuring that the tobacco seeds will not escape from the gap while ensuring the normal rotation of the rotating disk 602.

[0036] Wheels are installed at the four corners of the bottom of the vehicle body 1, and a push handle is installed on one side of the vehicle body 1.

[0037] Specifically, a person pushes the handle to push the vehicle body 1 to move on the seed ditch that has been opened in the land. Since the tobacco seeds are intermittently output from the feeding hopper, the tobacco seeds are arranged at intervals in the ditch.

[0038] The use process of the present invention is: First, a person pushes the vehicle body 1 onto a seed ditch already opened in the soil by pushing a handle, and then fills tobacco seeds into the seed feeding hopper 3 .

[0039] Then, the motor 603 is started, and at the same time, a person pushes the vehicle body 1 to move on the seed ditch. The output shaft of the motor 603 rotates to drive the rotating disk 602 to rotate. When the through hole 1 6011 and the through hole 2 6021 are aligned, the tobacco seeds in the through hole 1 6011 can fall into the feed hopper 8 and continue to fall out from the seed outlet 4, so that the tobacco seeds can be sown in the seed ditch of the land. When the output shaft of the motor 603 continues to rotate, the through hole 1 6011 and the through hole 2 6021 are no longer aligned, and the tobacco seeds in the feed pipe 5 will fall into the through hole 1 6011 on the fixed disk 601, waiting to be transported to the feed hopper 8 next time. The motor 603 continues to run, so that the tobacco seeds are input into the seed ditch at intervals, realizing interval sowing.

[0040] In addition, while the output shaft of the motor 603 drives the rotating disk 602 to rotate, the output shaft of the motor 603 also drives the toggle plate 604 to rotate. After the toggle plate 604 rotates to a certain position, it will hit the ball 705. The ball 705 will move under the action of the spring 2 704, thereby causing the feed pipe 5 to shake, thereby facilitating the seeds in the feed pipe 5 to move downward into the through hole 1 6011, preventing blockage in the feed pipe 5.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
