Technical Field
[0001] The present invention relates to a sowing device, in particular to a sowing device. Background Art
[0002] Currently, existing sowing devices are complex and costly, and cannot effectively control the number of seeds per rice plant. At the same time, the operation is cumbersome and inconvenient for farmers to use, and also increases farmers' planting expenses. Based on the current problems, the present invention designs a sowing device that is simple to operate and has low manufacturing cost. Summary of the Invention
[0003] The object of the present invention is to provide a low-cost, quick-to-use sowing device.
[0004] The technical solution adopted by the present invention to solve its technical problems is: a sowing device, including a motion mechanism, a silo and a sowing mechanism, wherein a plurality of hoppers are arranged on the silo, some of the hoppers are arranged along the length direction of the silo, and some of the hoppers can also be arranged along the width direction of the silo, and a sowing mechanism is arranged between the hoppers, optionally, a sowing mechanism is arranged between two hoppers, optionally, a sowing mechanism is arranged between three hoppers, and optionally, a sowing mechanism is arranged between four hoppers; one end of the sowing mechanism extends into the hopper and cooperates with the discharge port of the hopper, and the other end of the sowing mechanism contacts with the motion mechanism, and the motion mechanism is arranged at the bottom end of the silo, and the motion mechanism contacts with the sowing mechanism and controls the up and down movement of the sowing mechanism; The silo of the present invention comprises a silo bracket, a silo support rod, a silo shell and a hopper, wherein the silo shell is arranged at the upper end of the silo bracket, the silo bracket supports the silo shell, the hopper is arranged in the silo shell, the silo support rod is arranged at the lower end of the silo bracket, and the silo support rod is movably connected to the motion mechanism; The motion mechanism of the present invention includes walking wheels, a transmission shaft and a polygonal working plate. The walking wheels are respectively arranged on both sides of the silo. The two walking wheels arranged on both sides of the silo do not affect each other. The transmission shaft is movably connected to the silo support rod of the silo. One end of the transmission shaft is connected to the walking wheels, and the other end of the transmission shaft is connected to the polygonal working plate. The sowing mechanism of the present invention includes a push rod, an adjustment assembly and a sowing rod, the upper end of the push rod is connected to the sowing rod through the adjustment assembly, one end of the sowing rod is connected to the adjustment assembly, and the other end is close to the discharge port of the hopper or is at the same level as the discharge port, so as to ensure that the seeds in the hopper will not fall out by themselves when the sowing rod is initially stationary, but can be sown by the sowing rod when the sowing rod moves up and down, the adjustment assembly can adjust the distance between the sowing rod and the discharge port of the hopper, and the lower end of the push rod is provided with a roller, which is in contact with the polygonal working plate; The end of the sowing rod is arranged vertically to the lower opening of the hopper, wherein the ratio of the circumference of the walking wheel to the lift of the polygonal working plate is a fixed coefficient K, K=sowing grain spacing / single lift of the polygonal working plate, and the lift refers to the distance the polygonal working plate is lifted when it rotates, and also refers to the height of the sowing mechanism when the polygonal working plate rotates.
[0005] The polygonal working plate is driven by the walking wheel, which drives the sowing rod to perform precise reciprocating sowing operations. The innovative fixed parameter linkage system is adopted: the circumference L of the walking wheel, the lift H of the polygonal working plate and the hopper spacing D satisfy L=πD / H×K, which realizes the mathematical control of the sowing amount per unit area. The specially designed adjustment component can fine-tune the single sowing amount within the range of ±5%, so that the hybrid rice sowing accuracy reaches 1~5 seeds / hole. This device does not require its own power and has a simple and reliable structure. It is particularly suitable for precision sowing operations in large-scale hybrid rice seed fields.
[0006] The silo support rod of the present invention is provided with a plurality of conduits. The diameter of the transmission shaft is slightly smaller than the inner diameter of the conduits. The transmission shaft passes through the conduits and rotates inside the conduits.
[0007] The traveling wheel of the present invention is provided with a plurality of power plates at equal intervals along the outer diameter direction of the traveling wheel, so as to prevent the traveling wheel from slipping in paddy fields, muddy ground or other conditions with low friction.
[0008] The polygonal working plate of the present invention is vertically connected to the transmission shaft, and the outer edge of the polygonal working plate contacts the roller, so that the roller rolls along the outer edge of the polygonal working plate. The sowing mechanism can move up and down by the roller rolling along the outer edge of the polygonal working plate, so that the material falls evenly from the silo into the field.
[0009] The silo bracket of the present invention is provided with a through hole, which is slightly larger than the push rod. The push rod passes through the silo bracket to the upper end of the silo shell through the through hole, thereby enhancing the upward and downward movement of the push rod along the silo bracket and preventing the push rod from moving in other directions to affect the discharge volume.
[0010] The silo bracket of the present invention is also provided with a trailer, which is vertically connected to the silo bracket and extends forward and backward toward the silo bracket, so that the device can move in two directions, forward and backward. The trailer can be hung with other power and / or the device can be added. The power includes traction mechanisms such as tractors, plows, rice transplanters and oxen.
[0011] The adjustment assembly of the present invention includes an adjustment piece and an adjustment nut. The upper end of the push rod is provided with a thread that matches the adjustment nut. The push rod is fixedly connected to the adjustment piece through the adjustment nut. The height of the adjustment piece can be adjusted by rotating the adjustment nut clockwise or counterclockwise.
[0012] The upper end of the sowing rod of the present invention is provided with a thread that cooperates with the adjusting nut. The sowing rod is fixedly connected to the adjusting member through the adjusting nut. The distance between the sowing rod and the discharge port can be adjusted by rotating the adjusting nut clockwise or counterclockwise.
[0013] The polygonal shape of the polygonal working plate of the present invention includes triangle, quadrilateral, pentagon, hexagon, heptagon and the like.
[0014] When the polygonal shape of the polygonal working plate of the present invention is a triangle, the present invention sows three clumps, three seeds or three seeds when the walking wheel rotates one circle.
[0015] When the polygonal working plate of the present invention is a quadrilateral, the present invention sows four clumps, four seeds or four seeds when the walking wheel rotates one circle.
[0016] When the polygonal shape of the polygonal working plate of the present invention is a pentagon, the present invention sows five seeds or five grains when the walking wheel rotates one circle.
[0017] When the polygonal working plate of the present invention is a hexagon, the present invention sows six seeds or six grains when the walking wheel rotates one circle.
[0018] When the polygonal working plate of the present invention is a heptagon, the present invention sows seven seeds or seven grains when the walking wheel rotates one circle.
[0019] The hopper of the present invention is wide at the top and narrow at the bottom, and the inner surface of the hopper is smooth. The inner surface of the upper end of the hopper has a large slope, which ensures that all seeds can be hammered out freely. The discharge port of the hopper is set outward through the silo bracket, which reduces the distance between the discharge port and the ground.
[0020] The two running wheels of the motion mechanism of the present invention are respectively arranged on both sides of the silo. The two running wheels arranged on both sides of the silo do not affect each other. When the device turns, the inner running wheel stops or rotates with a small amplitude, and the outer running wheel rotates normally, so that the turn is achieved without affecting normal sowing, ensuring that the sowing work continues without adding additional workload.
[0021] The working principle of the present invention is as follows: when the device moves, the traveling wheel starts to rotate, and the traveling wheel drives the transmission shaft and the polygonal working plate to rotate at the same time. When the polygonal working plate rotates, the roller rolls along the outer edge of the polygonal working plate. Since the polygonal working plate is polygonal, the push rod with the roller moves up and down at a uniform speed, and the adjusting component at the upper end of the push rod also moves up and down with the push rod, thereby further driving the sowing rod to move up and down at a uniform speed, so that the sowing rod evenly helps the material leave the hopper, and each time the sowing rod moves, a certain number of seeds can be sown as required, and the number of seeds sown each time can be controlled by controlling the relative height between the sowing rod and the discharge port plane.
[0022] The beneficial effects of the present invention are: uniform sowing is achieved through the coordinated movement of the rollers and the polygonal working plate. Since the spacing between the hoppers is fixed, the circumference of the running wheels is fixed, and the correlation coefficient with the polygonal working plate is also fixed, the sowing rate per unit area can be strictly controlled. Therefore, it is particularly suitable for sowing hybrid rice, which requires strict seeding requirements. Furthermore, the device is easy to operate, has a simple structure, and is low in cost, making it very suitable for large-scale promotion. It is primarily used for sowing rice and other seeds.
