Description

Technical Field

[0001] This utility model belongs to the field of forestry seed planting technology, and specifically relates to a forestry seed screening and cleaning device. Background Technology

[0002] Currently, seed screening equipment generally suffers from a single screening method, relying on variables such as weight and volume to screen seeds and impurities. This makes it difficult to comprehensively and accurately screen out high-quality seeds. Furthermore, during the field collection, transportation, and storage process, seeds and their surfaces accumulate a lot of mud and impurities. If the seeds are not cleaned, these impurities will seriously interfere with the seed quality assessment during the screening process, leading to many inferior seeds being mixed into the seedling stage. This affects the subsequent growth of trees and seriously impacts the quality and efficiency of seed screening.

[0003] A search revealed a forestry seed screening device (CN221017219U), comprising a base plate with support rods installed at the four corners of the top of the base plate. Multiple sets of vertically parallel swaying frames are installed between the four sets of support rods. An edge strip is integrally formed at the bottom of the inner ring of each swaying frame. A collection basket placed on top of the edge strip is located inside the bottommost swaying frame, while sieve frames placed on top of the edge strips are located inside the remaining swaying frames. A sliding support assembly is installed between two sets of support rods on the same side of the swaying frame, and the sliding support assembly is connected to the side of the swaying frame.

[0004] Further search revealed that, according to prior art publication number CN118491855A, a forestry seed screening device includes a base, a screening box, a vibration mechanism, a multi-stage seed screening mechanism, a feeding hopper, and a feeding mechanism. The screening box is installed on the top surface of the base and is inclined on the top surface of the base. The vibration mechanism is provided on the outside of the screening box, and the multi-stage seed screening mechanism is provided inside the screening box. A feeding hopper is fixedly installed on one side of the top of the screening box, and a feeding mechanism is provided on the side of the inside of the screening box near the feeding hopper.

[0005] The existing technologies mentioned above only use the size of the seeds for screening, and do not clean the seeds, making it difficult to comprehensively and accurately screen out high-quality seeds, which seriously affects the quality and efficiency of seed screening. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a forestry seed screening and cleaning device. By combining the screening of the screening mechanism with the cleaning of the seeds in the cleaning chamber, the seeds are comprehensively screened based on multiple variables such as volume and weight. This improves the problem of the existing equipment having a single screening method and being unable to comprehensively and accurately screen out high-quality seeds. In addition, the stirring mechanism accelerates the removal of dirt, dust and other contaminants from the seed surface during seed cleaning, achieving efficient seed cleaning.

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1) By combining the screening of the screening mechanism with the cleaning of the seeds in the cleaning chamber, the seeds are comprehensively screened based on multiple variables such as volume and weight. This improves the problem of the existing equipment having a single screening method and being unable to comprehensively and accurately screen out high-quality seeds. In addition, the stirring mechanism accelerates the removal of dirt, dust and other contaminants from the seed surface during seed cleaning, achieving efficient seed cleaning.

[0021] 2) The seed-spreading mechanism evenly spreads the seeds onto the filter plate in the screening mechanism. Motor II drives the gear to rotate the rotating collar, which in turn drives the fixed frame and the filter plate to rotate synchronously, ensuring that the seeds are evenly spread on the filter plate. Compared with directly pouring the seeds onto the filter plate, this effectively avoids the seeds accumulating in local areas of the filter plate, causing excessive local pressure on the screening mechanism and reducing the screening efficiency of the screening mechanism.

[0034] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-11 The technical solution of this utility model will be further described in detail below.

[0035] A forestry seedling screening and cleaning device includes a screening chamber 101, a connecting channel 102, a cleaning chamber 103, a suction pipe 104, a seed-spreading mechanism 2, a screening mechanism 3, a stirring mechanism 4, and a filter box 5. The screening chamber 101 is located at the top end of the connecting channel 102 and is connected to the connecting channel 102. The cleaning chamber 103 is located at the bottom end of the connecting channel 102 and is connected to the connecting channel 102. A fixing plate 105 is provided on the top of the screening chamber 101. The suction pipe 104 and the seed-spreading mechanism 2 are installed on the top of the screening chamber 101 through the fixing plate 105. The screening mechanism 3 is located inside the screening chamber 101. The stirring mechanism 4 is installed on the connecting channel 102 and located inside the cleaning chamber 103. The filter box 5 is located inside the cleaning chamber 103.

[0036] The screening chamber 101 is provided with a mounting groove I 1011. The screening mechanism 3 is installed in the screening chamber 101 through the mounting groove I 1011. The screening chamber 101 is designed to be discontinuous. Both sections of the screening chamber 101 are provided with flanges 1012. The two sets of flanges 1012 are fixedly connected by bolts and nuts. Sealing strips are provided at the contact ends of the two sections of the screening chamber 101. The discontinuous design of the screening chamber 101 is to facilitate the installation and maintenance of the screening mechanism 3. A wiring conduit 1013 is provided at the bottom of the screening chamber 101. The power supply cable for the external power source is connected through the wiring conduit. Pipe 1013 connects to screening mechanism 3. The cleaning chamber 103 is provided with mounting groove II 1033. Filter box 5 is slidably installed in the cleaning chamber 103 through mounting groove II 1033. The cleaning chamber 103 is provided with overflow port 1031 on one side, which is located on the top side of filter box 5. The cleaning chamber 103 is provided with water inlet 1035 on one side, which is higher than overflow port 1031. The cleaning chamber 103 is provided with drain port 1032 at the bottom. The cleaning chamber 103 is provided with inspection port 1034 on one side for installing and inspecting stirring mechanism 4.

[0037] The suction pipe 104 is provided in two sets, and the fixed plate 105 is provided with two sets of sliding grooves 1051. The suction pipe 104 is slidably connected to the fixed plate 105 through the sliding grooves 1051. The suction pipe 104 is located at the top of the screening chamber 101. The suction pipe 104 has a telescopic design. The suction pipe 104 is used to suck up impurities such as mud and stones screened out by the screening mechanism 3. This is the prior art and will not be described in detail here.

[0038] The filter box 5 has an open design, and a filter screen is provided at the bottom of the filter box 5. The filter screen aperture is smaller than the seed diameter, and a handle is provided at the extraction end of the filter box 5.

[0039] As described above: the seed-spreading mechanism 2 evenly spreads a fixed amount of seeds to be treated onto the screening mechanism 3 in the screening chamber 101. The screening mechanism 3 performs preliminary screening to separate impurities such as stones, mud, and weeds mixed in with the seeds. The suction pipe 104 sucks out the impurities screened out by the screening mechanism 3. The seeds slide down through the connecting channel 102 into the filter box 5 in the cleaning chamber 103. Then, clean water enters the cleaning chamber 103 through the water inlet on one side of the cleaning chamber 103. After the clean water submerges the seeds, the stirring mechanism 4 stirs the seeds in the filter box 5 to accelerate the removal of dirt, dust and other contaminants attached to the seed surface. This causes the unripe seeds and dirt, dust and other contaminants to suspend on the water surface and be discharged through the overflow port 1031. Meanwhile, the mud and sand that are not easily suspended pass through the bottom of the filter box 5 and are discharged with the sewage through the drain port 1032.

[0040] After the unripe seeds, soil, dust and other impurities are discharged through the overflow port 1031, the sewage outlet 1032 is opened to discharge the mud and sand. After multiple washings, until clean water is discharged from the overflow port 1031, the filter box 5 is pulled out to obtain clean seeds.

[0041] The seed-spreading mechanism 2 includes a quantitative hopper 21, a discharge pipe 22, a spiral blade 25, and a motor I 26. The quantitative hopper 21 is installed on the top of the screening chamber 101 via a fixing plate 105. The top of the quantitative hopper 21 is provided with a feed inlet 2101, and the bottom of the quantitative hopper 21 is provided with a sealing plate 23. The discharge pipe 22 is provided with two sets, and the bottom end of the discharge pipe 22 is connected to the bottom side of the quantitative hopper 21. The spiral blade 25 is rotatably installed on the discharge pipe 22. The motor I 26 is installed on the top of the discharge pipe 22, and the output shaft of the motor I 26 passes through the discharge pipe 22 and is fixedly connected to the spiral blade 25. The side wall of the discharge pipe 22 is provided with a discharge port 2201.

[0042] The bottom of the quantitative hopper 21 is provided with a guide block 24, which is fixedly connected to the sealing plate 23. The guide block 24 is conical in shape and guides the seeds into the discharge pipe 22 to prevent the seeds from accumulating at the bottom of the quantitative hopper 21.

[0043] As described above, a fixed amount of seeds to be processed are fed into the feed inlet 2101 at the top of the quantitative hopper 21. After falling to the bottom of the quantitative hopper 21, the seeds are guided by the guide block 24 into the two sets of discharge pipes 22. The spiral blades 25 of the motor I 26 rotate, and the spiral blades 25 gradually transport the seeds while rotating, discharging the seeds from the discharge outlet 2201 on the side wall of the discharge pipe 22. The discharged seeds fall onto the screening mechanism 3 in the screening chamber 101.

[0044] The screening mechanism 3 includes a filter plate 31, a rotating collar 32, a motor II 34, a spring I 37, a rotating shaft 311, a rotating rod 312, a pull rod 313, a sliding rod 314, a hammer head 316, and a spring II 318. The rotating collar 32 has a fixed frame 38 at its bottom, and two sets of telescopic rods 36 are mounted on the fixed frame 38. The bottom of each telescopic rod 36 has a damping block to reduce vibration damage to the device. The telescopic ends of the telescopic rods 36 are fixedly connected to the filter plate 31, and the filter plate 31 is slidably connected to the rotating collar 32. The outer diameter of the filter plate 31 matches the inner diameter of the rotating collar 32. A spring I 37 is sleeved on the telescopic rod 36. Two sets of mounting shells II 315 are provided on the fixing frame 38. The hammer head 316 is slidably installed in the mounting shell II 315. The hammering end of the hammer head 316 passes through the top of the mounting shell II 315, and the bottom end of the hammer head 316 passes through the fixing frame 38. A connecting plate 317 is provided in the middle of the hammer head 316. The connecting plate 317 is located in the mounting shell II 315 and is fixedly connected to the mounting shell II 315. A spring I 37 is sleeved on the hammer head 316. Two sets of springs II 318 are located at the upper and lower ends of the connecting plate 317, respectively. The hammer head 316 is hollow inside, and a sliding rod 314 is slidably installed inside the hammer head 316. A limiting block 319 is provided at the top of the sliding rod 314, and the outer diameter of the limiting block 319 matches the inner diameter of the hammer head 316. Springs III 320 are provided at both the upper and lower ends of the limiting block 319. The bottom spring III 320 of the limiting block 319 is sleeved on the sliding rod 314. The bottom end of the sliding rod 314 passes through the bottom of the hammer head 316 and is connected to the sliding rod 314. Rod 313 is hinged, and pull rod 313 is hinged to rotating rod 312. One end of rotating rod 312 is fixedly connected to rotating shaft 311. Rotating shaft 311 is rotatably mounted at the bottom of fixed frame 38. A bevel gear is provided in the middle of rotating shaft 311. Motor III 310 is provided at the bottom of fixed frame 38. The bevel gear on the output shaft of motor III 310 meshes with the bevel gear in the middle of rotating shaft 311. Mounting shell I 35 is provided at the bottom of fixed frame 38. Motor III 310, rotating shaft 311, rotating rod 312 and other structural components are all located inside mounting shell I 35.

[0045] The rotating collar 32 is provided with slewing bearings 33 on both the upper and lower sides. The bottom of the slewing bearing 33 is provided with a support platform. The support platform is fixedly connected to the rotating collar 32. The rotating collar 32 is rotatably installed in the mounting groove I 1011 in the screening chamber 101 through the slewing bearings 33. The slewing bearings 33 ensure that the rotating collar 32 rotates stably in the mounting groove I 1011. A sealing strip is provided at the rotatable connection between the rotating collar 32 and the mounting groove I 1011. A toothed ring is provided in the middle of the rotating collar 32. A motor II 34 is provided on the outside of the screening chamber 101. A gear is provided on the output shaft of the motor II 34. The gear meshes with the toothed ring in the middle of the rotating collar 32 through the mounting port on the side wall of the screening chamber 101. A protective shell is provided on the outside of the motor II 34 and the gear.

[0046] The bottom of the mounting housing I 35 is provided with a rotary electrical connector 39, and the power line of the screening mechanism 3 is connected to the power line in the wiring pipe 1013 through the rotary electrical connector 39.

[0047] The pore size of the filter plate 31 is larger than the seed diameter;

[0048] As can be seen from the above description: when the seeds fall onto the filter plate 31 in the screening mechanism 3 through the sowing mechanism 2, the motor II 34 drives the gear to rotate the rotating collar 32, which in turn drives the fixed frame 38 and the filter plate 31 to rotate synchronously, ensuring that the seeds are evenly spread on the filter plate 31.

[0049] Motor III 310 drives rotating shaft 311 to rotate rotating rod 312. Rotating rod 312 pulls sliding rod 314 through pull rod 313 to slide inside hammer head 316. With the help of spring II 318 and spring III 320 for buffering, it drives hammer head 316 to move up and down continuously. The top of hammer head 316 repeatedly hammers filter plate 31, causing filter plate 31 to generate high-frequency small-amplitude vibration. Since the pore diameter of filter plate 31 is larger than the seed diameter, the seed falls through the filter hole of filter plate 31. Stones, mud, weeds and other impurities remain on filter plate 31 and are sucked away by suction pipe 104.

[0050] The stirring mechanism 4 includes a motor IV 41, a coupling 42, a telescopic rotating shaft 43, and a fixed base 47. Two sets of telescopic rotating shafts 43 are provided, and each set is rotatably connected to the fixed base 47. The telescopic rotating shafts 43 pass through the connecting channel 102 and are located within the cleaning chamber 103. A synchronous pulley is provided at the top of each telescopic rotating shaft 43, and the two sets of synchronous pulleys are connected by a synchronous belt drive. The motor IV 41 is mounted on the top of one set of telescopic rotating shafts 43, and the output shaft of the motor IV 41 is fixedly connected to the telescopic rotating shaft 43 via the coupling 42. The outer side of both Ⅳ41 and the synchronous belt is provided with a protective shell. The fixed end and the telescopic end of the telescopic rotating shaft 43 are provided with a connecting plate 44. Electric push rods 45 are provided on both sides of the telescopic rotating shaft 43. The telescopic end of the electric push rod 45 is fixedly connected to the connecting plate 44 of the telescopic end of the telescopic rotating shaft 43. The outer side of the electric push rod 45 is provided with a protective shell. The top of the connecting plate 44 of the fixed end of the telescopic rotating shaft 43 is provided with a rotary electric connector 39. The bottom of the telescopic end of the telescopic rotating shaft 43 is provided with a stirring plate 46. The sides of the stirring plate 46 are rounded to prevent scratching the seeds.

[0051] As described above, after the seeds are submerged in clean water, the two sets of telescopic rotating shafts 43 of motor IV 41 rotate, and the electric push rod 45 pushes the connecting plate 44 at the telescopic end of the telescopic rotating shaft 43 to adjust the length of the telescopic rotating shaft 43, thereby driving the stirring plate 46 to penetrate deeper into the filter box 5 to stir and clean the seeds, accelerating the removal of dirt, dust and other contaminants from the seed surface, and suspending the unripe seeds and dirt, dust and other impurities on the water surface. After cleaning, the electric push rod 45 retracts the connecting plate 44 at the telescopic end of the telescopic rotating shaft 43, driving the stirring plate 46 to be lifted out of the filter box 5, and the cleaned water is discharged from the drain port 1032. Then, the filter box 5 is pulled out to obtain clean seeds.
