[0001] The invention relates to the field of bean sowing, and in particular to a turnover type precise quantitative bean sowing device and a sowing method. Background Art

[0002] The existing mung bean cultivation process requires a lot of manual labor and has high labor costs. In addition, the existing mung bean sowing operation mode is usually based on broadcasting, which not only affects the seedling survival rate, but also causes uneven distribution of seeds on the land. Different sowers have different strengths and methods, resulting in inconsistent seed density and spacing, which affects the growth and yield of crops and increases the cost of mung bean cultivation.

[0003] In recent years, small tractors and mechanical seeders have been used to sow mung beans. However, the filling performance of the seeds in the holes of the mechanical seeders will decrease under tilted conditions, which will aggravate the phenomenon of overseeding and missing seeding. In addition, small tractors and mechanical seeders require a higher initial investment, and also require additional costs in terms of maintenance and repair. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] Example 1

[0046] See also Figure 1-Figure 6 A flip-type precise quantitative bean sowing device comprises a sowing driving mechanism 1, a sowing screening mechanism 2, a grain storage bin 3, a suction force providing mechanism 4, and a flipping mechanism 5.

[0047] The sowing drive mechanism 1 includes a driving source 11, a first gear 12, a second gear 13, and a transmission rod 14. The driving source 11 is a servo motor, and its output end is connected to the first gear 12 to drive the first gear 12 to rotate. The rack of the second gear 13 is meshed with the rack of the first gear 12. One end of the transmission rod 14 is connected to the second gear 13, and the other end extends into the grain storage bin 3 and is connected to the screening unit 21 of the sowing screening mechanism 2. The driving source 11 drives the first gear 12 to rotate, and then drives the second gear 13 to rotate. The second gear 13 drives the transmission rod 14 to rotate, and then drives the screening unit 21 of the sowing screening mechanism 2 to rotate.

[0048] The sowing and screening mechanism 2 is placed in the mounting hole 3b of the grain storage bin 3, and is used to screen and transport beans. It includes a screening unit 21 and a separation unit 22. The screening unit 21 includes a disc 211 and a plurality of screening holes 212 arranged in a circumferential array on the edge of the disc 211. The diameter of the screening hole 212 is larger than the diameter of a single sowing object (beans). The disc 211 is connected to the transmission rod 14. In this embodiment, in order to prevent the beans from being sucked or stuck, the screening hole 212 includes an opening 7, a limiting portion 8, and an arc-shaped cavity 9. The opening 7 is placed at the outermost edge of the disc 211 and is located between the limiting portion 8 and the arc-shaped cavity 9; in the direction of rotation of the disc, the limiting portion 8 is located behind the arc-shaped cavity 9, and the arc-shaped cavity 9 is concave in the direction of rotation of the disc, and the limiting portion 8 is convex in the direction of rotation of the disc. This structure facilitates the screening and transportation of beans. The partition unit 22 includes a filter net, which is placed between the screening unit 21 and the suction providing mechanism 4 to prevent the sowing material from being sucked out under the suction of the suction providing mechanism 4 or to prevent beans from entering the suction providing mechanism 4 .

[0049] The suction providing mechanism 4 is arranged opposite to the mounting hole 3b on the grain storage bin 3, and is used to provide suction, and includes a housing 41 and a duct fan 42. The housing 41 is connected to the grain storage bin 3, and the duct fan 42 is placed in the housing 41, behind the partition unit 22. The suction force generated by the suction providing mechanism 4 facilitates the sowing to gather near the screening unit 21, and facilitates the sowing to fall into the sieve hole 212. Under the rotation of the screening unit 21, the sowing falls into the sowing pipe 6.

[0050] The grain storage bin 3 is used to store beans, and a sowing hole 3a is provided at the bottom thereof, which is connected to the inlet of the sowing pipe 6. The bottom plate 31 of the grain storage bin 3 is an inclined plate, which facilitates the sowing (beans) to be gathered on the screening unit 21 by gravity. In this embodiment, the angle between the bottom plate 31 and the horizontal plane is greater than 6 degrees. In order to facilitate the installation or placement of the entire device, a horizontal support plate 32 can be installed under the bottom plate 31.

[0051] The turning mechanism 5 is used for tamping soil and is installed on one side near the sowing hole. It includes a fixed mounting plate 51, a connecting rod unit, and a tamping plowshare 56. The fixed mounting plate 51 is installed on the grain storage bin 3. The connecting rod unit includes a first connecting rod 52, a second connecting rod 53, a third connecting rod 54, and a fourth connecting rod 55; the first connecting rod 52 and the second connecting rod 53 are arranged in parallel, and one end of the first connecting rod 52 and the second connecting rod 53 is respectively hinged to the third connecting rod 54, and the other end of the first connecting rod 52 and the second connecting rod 53 is respectively hinged to the fourth connecting rod 55; the third connecting rod 53 and the fourth connecting rod 54 are hinged to the fixed mounting plate 51, and the fourth connecting rod 54 is fixedly connected to the sowing pipe 6. The tamping plowshare 56 is installed at the outlet of the sowing pipe 6, and its front end is tapered to facilitate tamping soil.

[0052] When the storage bin 3 is full of sowing materials, since the bottom plate 31 of the storage bin 3 is arranged at an angle with the horizontal plane, under the action of gravity, the sowing materials in the storage bin 3 are tilted to one side of the screening unit 21, and the suction providing mechanism 4 provides suction, and under the action of the suction of the duct fan 42, the sowing materials (beans) stored in the storage bin 3 are sucked into the screening holes 212; the driving source 11 of the sowing driving mechanism 1 drives the screening unit 21 to rotate through the first gear 12 and the second gear 13; when the screening hole 212 rotates to just above the sowing hole 3a, the beans fall into the sowing hole 3a, and then enter the sowing pipe 6; the sowing pipe 6 is lifted, and the tamping plow head 56 moves upward to tamp the soil. At this time, the beans in the sowing pipe 6 fall into the soil, and the sowing of the sowing materials is completed.

[0053] The servo motor has the following advantages: 1. High precision: it realizes closed-loop control of position, speed and torque, and overcomes the problem of stepping out of step of the stepper motor; 2. High speed: it has good high-speed performance, and the rated speed can generally reach 2000-3000 rpm, which can improve the picking efficiency; 3. Adaptability: it has strong overload resistance and can withstand loads three times the rated torque. It is particularly suitable for occasions with instantaneous load fluctuations and requirements for rapid start-up; 4. Stability: it runs smoothly at low speed, and will not produce stepping operation phenomena similar to stepper motors when running at low speed. It is suitable for occasions with high-speed response requirements; 5. Timeliness: the dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds, which is convenient for controlling the operation of the picking device.

[0054] Gear transmission has the following advantages: 1. Constant instantaneous transmission ratio: Gear transmission has high stability, because the instantaneous transmission ratio remains constant, making the transmission process more stable. 2. Accurate transmission ratio: The transmission ratio of gear transmission can be precisely designed according to demand to meet the requirements of various working conditions. 3. High working efficiency: Gear transmission has high efficiency and can transmit greater power with smaller volume and weight, making the equipment lighter. 4. Long life: The material and structural design of gear transmission give it a long service life and can maintain stable operation under harsh environments such as high temperature and high pressure. 5. High load-bearing capacity: Gear transmission has a high load-bearing capacity, can withstand large loads and torques, and is suitable for various heavy-load conditions. 6. High reliability: Gear transmission has a simple structure, reliable working principle, is not prone to failure, and reduces the maintenance cost of equipment.

[0057] 1) Insert the tamping plowshare 56 into the soil;

[0058] 2) Turning on the suction providing mechanism 4, the suction of the suction providing mechanism 4 passes through the partition unit 22, so that the beans in the grain storage bin 3 are sucked into the sieve holes 212;

[0059] 3) Turn on the sowing drive mechanism 1 to drive the screening unit 21 to rotate; when the sieve hole 212 rotates to the top of the sowing hole 3a, the beans fall into the sowing hole 3a and then enter the sowing pipe 6; at this time, the beans in the grain storage bin 3 continue to be sucked into the sieve hole 212;

[0060] 4) The sowing pipe 6 is lifted, and the tamping plowshare 56 moves upward to tamp the soil. At this time, the beans in the sowing pipe 6 fall into the soil, and the sowing of one bean is completed;

[0061] 5) Repeat the above steps until the sowing is completed.

[0062] When the work is completed, in order to reduce the space utilization of the device in the vertical direction, the turning mechanism 5 is used to rotate the tamping plowshare 56 and the sowing pipe 6 by 90 degrees so that the tamping plowshare 56 and the sowing pipe 6 are at the same horizontal position as the storage bin 3.
