Description

Technical Field

[0001] The invention belongs to the technical field of cleaning devices, and in particular relates to a forestry seed cleaning device. Background Art

[0002] In the field of forestry planting, seed cleaning is an important step before sowing, which is directly related to the germination rate of seeds and the subsequent growth of trees. Traditional forestry seed cleaning devices usually adopt a simple soaking and flushing method, spraying water on seeds through fixed nozzles to achieve the purpose of removing impurities.

[0003] However, the traditional cleaning device has a relatively simple cleaning method and cannot fully expose the seeds to the spraying range of the water flow. Seeds vary in shape and size, and it is difficult for the fixed-position nozzle to ensure that the high-pressure water flow can evenly and effectively cover all parts of the seeds, especially for stubborn impurities attached to the surface of the seeds, which affects the cleaning effect and efficiency of the seeds. In addition, due to the large differences in seed sizes, the existing fixed-structure cleaning device has poor flexibility. Cleaning different seeds requires replacing devices of different specifications, which not only increases the cost of use, but also affects the versatility and practicality of the cleaning device.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is in use, the driving motor is operated so that the cleaning rod drives the seeds inside the cleaning box to move back and forth and rise above the liquid surface, so that the seeds are fully exposed to the spray range of the nozzle, and the high-pressure water flow directly impacts the surface of the seeds, which can effectively remove stubborn impurities attached to the seeds and improve the cleaning effect and efficiency.

[0014] By rotating the screw rod to adjust the initial positions of the rectangular block and the swing block, the swing angle of the cleaning rod can be flexibly adjusted, thereby adjusting the distance between the seeds and the nozzle, so that the present invention can clean seeds of different sizes and enable the high-pressure water flow to evenly and effectively cover all parts of the seeds, thereby improving versatility and practicality.

[0015] When the support frame swings back and forth, the combination of the first damping spring and the pulley makes the first gear rod slide back and forth on the support frame, and cooperates with the second gear to drive the rotating rod and the cleaning rod to rotate back and forth. This design allows the user to more accurately control the cleaning force and range of the seeds by adjusting the rotation angle of the cleaning rod, thereby avoiding seed damage caused by excessive cleaning, and ensuring the uniformity and effectiveness of cleaning. During the cleaning process, the stirring effect of the water flow promotes the circulation of water in the cleaning box and improves the overall cleaning efficiency. At the same time, the reciprocating swing of the cleaning rod and the rising movement of the seeds also increase the contact area and time between the seeds and water, further enhancing the cleaning effect.

[0016] The servo motor drives the nozzle to reciprocate on the top of the cleaning box, and cooperates with the reciprocating rotation of the cleaning rod to achieve dynamic correspondence between the nozzle spray angle and the seed position, ensuring the accuracy and comprehensiveness of the spray cleaning, improving the cleaning effect, and more effectively removing impurities and dirt on the seed surface.

[0017] The reciprocating rotation of the stirring paddle can make the cleaning liquid form a vortex, so that the cleaning liquid and the seeds are fully in contact, making it easier to peel off the impurities and dirt attached to the seeds, thereby accelerating the decomposition of the dirt.

[0018] The up and down movement of the stirring paddle promotes the horizontal flow and vertical convection of the cleaning liquid, so that the cleaning liquid can cover the surface of the seeds more comprehensively. This comprehensive cleaning method helps to improve the utilization rate of the cleaning liquid and can completely remove impurities and dirt on the surface of the seeds.

A first gear rod 417 slidably installed in the vertical groove is fixedly connected to the top of the first damping spring 416, and a pulley 418 slidably adapted to the arc frame 12 is provided at the bottom of the first gear rod 417. The first gear rod 417 moves downward under the elastic tension of the first damping spring 416, so that the pulley 418 slides in contact with the outer wall of the arc frame 12; The inner end of the support frame 414 is rotatably connected to a rotating rod 419 , and the cleaning rod 415 is fixedly mounted on the rotating rod 419 . Both ends of the rotating rod 419 are fixedly connected to second gears 420 meshing with the first gear rod 417 .

[0023] In the embodiment of the present invention, the driving motor 43 is started to drive the first rotating block 44 to rotate synchronously. When rotating, the first rotating block 44 cooperates with the first connecting rod 45 and the adjusting block 411 to drive the rectangular block 49 and the swing block 47 to reciprocate on the positioning shaft 46. The swing block 47 cooperates with the lever 48, the swing groove 413 and the movable frame 412 to drive the positioning rod 41, the support frame 414 and the cleaning rod 415 to reciprocate, so that the cleaning rod 415 reciprocates around the positioning rod 41 as the axis. During the reciprocating rotation, the cleaning rod 415 drives the seeds inside the cleaning box 1 to rise above the liquid surface, so that the seeds are fully exposed to the spraying range of the nozzle 3. The nozzle 3 sprays and cleans the seeds above the liquid surface, and the high-pressure water flow directly impacts the surface of the seeds, thereby improving the cleaning effect. The high-pressure water flow can not only directly wash away the stubborn impurities attached to the seeds, but also promote the circulation of water in the cleaning box 1 through the stirring effect of the water flow, thereby improving the cleaning efficiency. By rotating the screw rod 410, the adjusting block 411 is driven to slide in the groove, thereby adjusting the initial positions of the rectangular block 49 and the swing block 47, and then changing the swing angles of the movable frame 412, the positioning rod 41, the support frame 414 and the cleaning rod 415, so that the swing angle of the cleaning rod 415 can be flexibly adjusted according to the size of the seeds, that is, by controlling the swing angle of the cleaning rod 415 to adjust the distance between the seeds and the nozzle 3, the high-pressure water flow sprayed by the nozzle 3 can evenly and effectively cover the surface of seeds of different sizes. For larger seeds, the swing angle of the cleaning rod 415 can be increased to make the seeds rise to a higher position, so that the water flow sprayed by the nozzle 3 can fully wash all parts of the seeds; for smaller seeds, reducing the swing angle of the cleaning rod 415 can avoid the seeds from colliding with each other due to excessive movement and causing breakage, while ensuring that the water flow can be concentrated and effectively clean the seeds. This flexible adjustment function greatly improves the adaptability of the cleaning device to seeds of different sizes. When the support frame 414 swings back and forth, under the action of the pulling force of the first damping spring 416, the pulley 418 always keeps sliding in contact with the outer wall of the arc frame 12. Since the arc frame 12 is arc-shaped, the first gear rod 417 can slide back and forth on the support frame 414, so that the first gear rod 417 cooperates with the meshing second gear 420 to drive the rotating rod 419 and the cleaning rod 415 to rotate back and forth. By adjusting the rotation angle of the cleaning rod 415, the cleaning force and range of the seeds can be more accurately controlled, and the impurities on the surface of the seeds can be thoroughly washed away.

The output end of the servo motor 59 is rotatably connected to the second rotating block 510 via a rotating shaft, and the two rotating shafts are transmission-connected via a synchronous pulley transmission member 512. The other end of the second rotating block 510 is rotatably connected to a second connecting rod 511, and the other end of the second connecting rod 511 is movably connected to the slide plate 53. The outer wall of the vertical rod 54 is fixedly connected to a limit block 519, a second damping spring 520 sleeved on the vertical rod 54 is arranged between the limit block 519 and the fixed plate 51, a movable rod 514 is arranged between the limit block 519 and the third gear 518, a sliding groove 515 is opened on the surface of the movable rod 514, and the movable rod 514 is slidably connected to the vertical rod 54 through the sliding groove 515, a push rod 516 is fixedly connected to one side of the movable rod 514, and a sliding rod 517 is arranged at the outer end of the push rod 516; An L-shaped sliding groove 57 is formed on the surface of the horizontal plate 52 , and an inclined groove 58 is formed on the surface of the sliding plate 53 . One end of the sliding rod 517 is slidably installed in the L-shaped sliding groove 57 and the inclined groove 58 .

[0025] In the embodiment of the present invention, the servo motor 59 is started to drive the rotating shaft and the second rotating block 510 to rotate synchronously, and the second rotating block 510 cooperates with the second connecting rod 511 to drive the slide plate 53 to slide back and forth on the horizontal plate 52, and the horizontal plate 52 drives the second gear rod 56 to move synchronously, so that when the second gear rod 56 reciprocates, the meshing first gear 22 drives the water pipe 2 and the nozzle 3 to reciprocate on the top of the cleaning box 1, thereby changing the spraying angle of the nozzle 3, so that the spraying angle of the nozzle 3 is reciprocated in coordination with the reciprocating rotation of the support frame 414, that is, when the cleaning rod 415 rotates counterclockwise, the nozzle 3 rotates clockwise, and when the cleaning rod 415 rotates clockwise, the nozzle 3 rotates counterclockwise, so that the spraying angle of the nozzle 3 corresponds to the seeds on the cleaning rod 415, thereby improving the spray cleaning effect; When the slide plate 53 moves back and forth, it drives the tooth plate 513 to move back and forth, so that the tooth plate 513 cooperates with the meshing third gear 518 to drive the vertical rod 54 and the stirring paddle 55 to rotate back and forth, so that the stirring paddle 55 stirs the cleaning liquid and seeds in the cleaning box 1, thereby improving the cleaning effect of the cleaning liquid on the seeds. The reciprocating rotation of the stirring paddle 55 can form a vortex in the cleaning liquid, so that the cleaning liquid and the seeds are fully in contact, so that the impurities and dirt attached to the seeds are easier to be peeled off, and the decomposition of the dirt is accelerated; When the slide plate 53 moves back and forth, the inclined groove 58 and the L-shaped groove 57 drive the slide bar 517, the top rod 516 and the movable rod 514 to move back and forth. The movable rod 514 slides on the vertical rod 54 in cooperation with the slide groove 515. When the slide bar 517 moves to the outermost side, the slide bar 517, the top rod 516 and the movable rod 514 move downward under the action of the L-shaped groove 57 and the inclined groove 58. When the movable rod 514 moves downward, the vertical rod 54 and the stirring paddle 55 move downward in cooperation with the limit block 519. When the slide bar 517 moves to one side of the nozzle 3, The movable rod 514, the top rod 516 and the sliding rod 517 cooperate with the second damping spring 520 to drive the vertical rod 54 and the stirring paddle 55 to move upward, so that the stirring paddle 55 mixes the cleaning liquid and seeds in the cleaning box 1 when moving up and down, thereby improving the cleaning effect of the cleaning liquid on the seeds. The up and down movement of the stirring paddle 55 not only promotes the horizontal flow and vertical convection of the cleaning liquid, so that the cleaning liquid can cover the surface of the seeds more comprehensively, but also, the convection and diffusion effects help to evenly distribute the cleaning liquid in the entire cleaning box 1, thereby improving the utilization rate of the cleaning liquid.
