Description

Technical Field

[0001] The invention belongs to the technical field of design and improvement of forestry and grassland machinery, and in particular relates to a special cleaning machine for Artemisia seeds. Background Art

[0002] In forestry and grass production and scientific research, seed quality is crucial to crop yield and quality. After harvest, seeds are often mixed with various impurities, such as stones, soil, plant debris, empty seeds, etc. In order to obtain pure and high-quality seeds, they need to be cleaned. The cleaning process includes operations such as removing impurities and grading by seed size and weight, among which screening is one of the important links. Traditional screening equipment mostly uses a fixed screen structure. This equipment has a simple structure and is usually composed of screens of different mesh sizes. The seeds roll or slide on the screen by gravity for screening. However, it has obvious defects. For some irregularly shaped, fluffy or humid seeds, it is easy to clog the screen holes, resulting in a sharp drop in screening efficiency, and even frequent shutdowns for cleaning. The movement of seeds on the fixed screen is single and can only rely on gravity. Some impurities similar in size to seeds are difficult to separate effectively and cannot be effectively screened.

[0012] Working principle: The seeds are first poured into the feed hopper 1, and the motor 1 drives the shaft 1 and the auger blades to rotate, and the seeds are transported from the guide tube to the top of the feed hopper 2, and enter the cleaning machine through the feed hopper 2. In the vibration assembly at the bottom of the cleaning machine, the motor 2 drives the shaft 2 to rotate, and the eccentric block on the shaft 2 rotates accordingly. The centrifugal force generated causes the fixed seat and the bottom plate to vibrate. This vibration is transmitted to the screen 1, screen 2 and screen 3 through the fixed column to screen the seeds. Screen 1 can screen seeds, weeds, debris and branches and leaves, so that larger impurities are isolated by screen 1, and the seeds and smaller impurities fall into screen 2 together. Screen 2 further screens the seeds and impurities, allowing the seeds to enter screen 3. Screen 3 then finely screens the seeds to separate the bran from the silkworm seeds, and the bran falls on the bottom plate due to vibration.

[0013] During the cleaning process, the centrifugal fan starts, forming a negative pressure inside it, sucking in the dust generated by the cleaning and the light impurities mixed in the seeds through the connecting pipe, air duct and dust hopper, and discharging them into the dust bag through the connecting pipe for collection. At the same time, motor three drives the threaded rod to rotate. Since the threaded rod is threadedly connected to brush one and the two ends of brush one are restricted by guide rod two, brush one makes reciprocating linear motion along guide rod two. Brush two at the bottom fits tightly to the screen under the action of spring two, follows the movement of brush one, cleans the screen, prevents the screen holes from being blocked, and ensures the continuity and stability of the screening work. The entire cleaning machine achieves efficient and accurate cleaning of Artemisia sericulture seeds through the coordinated work of various components.

[0014] The present invention provides a special cleaning machine for Artemisia seeds. It has the following beneficial effects: (1) The present invention realizes a multi-stage screening process of Artemisia seeds from raw materials containing various impurities to gradually separating pure seeds by screening through screen 1, screen 2 and screen 3 in sequence, greatly improving the precision and screening efficiency of seed cleaning. The fine screening and separation of bran and Artemisia seeds by screen 3 can effectively remove bran impurities in the seeds, ensure that the Artemisia seeds finally obtained have high purity, and solve the problem of low screening efficiency. (2) The present invention can accurately fit the surface of the screen through brush 1 and brush 2 under the action of spring 2, and timely clean the blockage on the edge of the screen hole, effectively avoiding the occurrence of screen hole blockage. It can clean the screen comprehensively and efficiently while it is working, greatly improving the cleaning efficiency and reducing the cleaning time and labor cost. This allows the screen to always maintain good screening performance and ensure the accuracy and speed of seed screening. (3) The present invention can perform real-time dust suction during the seed cleaning process through the dust collection mechanism, and promptly remove the dust generated by the screening operation and the light impurities mixed in the seeds. By removing the dust and light impurities, the possibility of these impurities mixing into the seeds is reduced, thereby improving the purity and quality of the seeds finally obtained, which makes the interior of the cleaning machine always maintain a relatively clean working environment and reduces the interference of dust and impurities on the subsequent screening process. (4) The present invention can continuously and stably transport seeds from feed hopper one to feed hopper two through the spiral conveying method of the auger blade, avoiding the accumulation and blockage of seeds during the conveying process. By controlling the speed of motor one and accurately positioning the guide pipe, the seed placement position and amount can be accurately controlled, so that the seeds can accurately enter the subsequent processing link of the cleaning machine, ensuring the stability and reliability of the cleaning process, and helping to improve the accuracy and quality of seed cleaning.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0017] Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 , Attachment Figure 6The embodiment of the present invention provides a special cleaning machine for Artemisia sericulture seeds, including a cover plate 1, side plates 2 are arranged on both sides of the cover plate 1, a bottom plate 37 is fixedly arranged at the bottom end of the side plate 2, a vibration component is arranged at the bottom end of the bottom plate 37, fixed columns 26 are symmetrically arranged at both ends of the upper surface of the bottom plate 37, a cleaning mechanism is arranged on the inner side of the fixed column 26, a screen 20 is arranged at the top of the fixed column 26, a screen 23 is arranged in the middle of the fixed column 26, a screen 38 is arranged at the bottom end of the fixed column 26, a plurality of sieve holes are opened on the upper surfaces of the screen 1 20, the screen 2 23, and the screen 3 38, a discharge hopper 3 is arranged at one end of the screen 1 20, and the screen 20 is provided with a plurality of sieve holes. A discharge hopper three 25 is provided at one end of the net two 23, and a discharge hopper two 4 is provided at one end of the screen three 38. Both ends of the discharge hopper one 3, the discharge hopper three 25 and the discharge hopper two 4 are arranged on the inner side of the side plate 2, and a support block 7 is symmetrically fixedly provided on the outer side of the side plate 2. A spring one 6 is provided at the bottom end of the support block 7, and a supporting device is provided at the bottom end of the spring one 6. The supporting device includes a base 5, and the top end of the base 5 is arranged at the bottom end of the spring one 6. A fixing rod 9 is fixedly provided on the side wall of each base 5, and a column 11 is provided on the upper surface of the fixing rod 9, and a bearing plate 10 is provided on the top end of the column 11, and a dust collecting mechanism is provided on the upper surface of the bearing plate 10.

[0018] Specifically, when materials containing seeds, weeds, debris, branches and leaves enter the cleaning machine and fall on the screen 20, the vibration component of the cleaning machine is started, driving the screen 20 to vibrate. Due to the size design of the sieve holes of the screen 20, larger impurities such as weeds, larger debris blocks and branches and leaves cannot pass through the sieve holes, but are isolated on the surface of the screen 20. Under the action of vibration, these larger impurities gradually move to one side, and the discharge hopper 3 discharges the screened impurities. However, since the size of seeds and smaller impurities is smaller than the sieve holes of the screen 20, they fall into the screen 2 23 through the sieve holes of the screen 20 under the action of gravity and vibration. The seeds and smaller impurities that fall into the screen 2 23 continue to be screened under the vibration of the screen 23. The sieve holes of the screen 23 are between the size of the screen 20 and the screen 3 38. It can further retain impurities larger than seeds on its surface, and under the action of vibration, move these impurities to one side and be discharged from the discharge hopper three 25, while allowing the seeds to fall into the screen three 38 through the sieve holes. The seeds entering the screen three 38 may also be mixed with lighter impurities such as bran. The screen three 38 finely screens the seeds under the action of vibration. Since the bran has a lighter specific gravity, the bran will gradually float on the surface of the seeds during the vibration process, and under the vibration generated by the vibration of the cleaning machine, the bran will be separated from the seeds and fall onto the bottom plate 37 below. The Artemisia selengensis seeds, due to their own weight and shape characteristics, remain on the screen three 38, completing the separation from the bran. The bran that falls on the bottom plate 37 gradually gathers at a specific position of the bottom plate 37 under the continuous vibration of the cleaning machine, making it convenient for the operator to collect it.

[0019] Through the sequential screening of the first screen 20, the second screen 23 and the third screen 38, a multi-stage screening process of the Artemisia selengensis seeds from the original material containing various impurities to the gradual separation of pure seeds is realized, which greatly improves the seed selection accuracy and screening efficiency. Through the graded screening of the three-layer screen, different impurities such as seeds, weeds, slag, branches and leaves, and bran can be effectively separated, solving the problem of low screening efficiency.

[0020] Please refer to the attached Figure 5 -Attached Figure 7 The cleaning mechanism includes two cross bars 40, a bearing seat is fixedly provided on one side of the cross bar 40, a motor three 33 is provided on the upper surface of the bearing seat, a threaded rod 43 is fixedly provided on the output end of the motor three 33, both ends of the threaded rod 43 are rotatably connected with the cross bar 40, both ends of the cross bar 40 are fixedly provided on one side of the fixed column 26, the outer wall of the threaded rod 43 is threadedly connected with a brush one 42, both ends of the brush one 42 are slidably connected with a guide rod two 41, both ends of the guide rod two 41 are provided on one side of the cross bar 40, a spring two 44 is symmetrically provided at the bottom end of the brush one 42, a brush two 45 is provided at the bottom end of the spring two 44, both ends of the brush two 45 are slidably connected with a guide rod one 39, and both ends of the guide rod one 39 are provided on one side of the fixed column 26.

[0021] Specifically, when the cleaning machine starts working, the motor 33 is started to drive the threaded rod 43 to rotate. Since the two ends of the threaded rod 43 are rotatably connected to the cross bar 40, and the brush 1 42 is threadedly connected to the outer wall of the threaded rod 43, and the two ends of the brush 1 42 can only slide linearly under the restriction of the guide rod 2 41, when the threaded rod 43 rotates, the brush 1 42 will make reciprocating linear motion along the guide rod 2 41, and the spring 2 44 at the bottom of the brush 1 42 has a certain elasticity, so that the brush 2 45 can fit closely to the screen while following the movement of the brush 1 42 The surface of the screen can ensure that the brush 2 45 always maintains good contact with the screen even if the screen has a slight up and down displacement during the vibration process. The two ends of the brush 2 45 also slide linearly under the restriction of the guide rod 1 39 to ensure the stability and directionality of its movement, so that it can accurately clean the screen. When the screen is screening, the continuously vibrating screen will cause seeds and impurities to move and roll on the screen surface. At this time, the reciprocating brushes 1 42 and 2 45 will promptly clean up the seeds and impurities stuck on the edge of the screen hole to prevent them from accumulating and clogging the screen hole.

[0022] The brush 1 42 and the brush 2 45 can precisely fit the surface of the screen under the action of the spring 2 44, and timely clean the blockage on the edge of the screen hole, effectively avoiding the blockage of the screen hole, so that the screen can always maintain good screening performance, ensure the accuracy and speed of seed screening, and improve the working efficiency and stability of the entire cleaning machine. Through the reciprocating motion of the brush and the design of tightly fitting the screen, foreign matter blocking the screen hole can be removed in time, solving the key problem of screen blockage and ensuring the continuous and efficient operation of the cleaning machine.

[0023] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 The dust collecting mechanism includes a centrifugal fan 22, the bottom end of the centrifugal fan 22 is arranged on the upper surface of the carrying plate 10, a connecting pipe 31 is fixedly arranged at the input end of the centrifugal fan 22, one end of the connecting pipe 31 is arranged with an air duct 32, a feed hopper 21 is arranged on one side of the air duct 32, a conveying device is arranged on one side of the feed hopper 21, a dust hopper 28 is arranged on the outer wall of the air duct 32, the outer wall of the dust hopper 28 is arranged on the upper surface of the cover plate 1, a connecting pipe 27 is fixedly arranged at the output end of the centrifugal fan 22, and a dust collecting bag 8 is arranged at one end of the connecting pipe 27.

[0024] Specifically, after the centrifugal fan 22 is started, a negative pressure environment is formed inside it. At this time, the dust hopper 28 is connected to the negative pressure area inside the fan through the connecting pipe 31 and the air duct 32. When the seeds enter the screen 20 for screening, dust will be generated due to the turning, friction of the materials and the separation process of the seeds and impurities. At the same time, the light impurities such as weeds, branches and leaves, bran mixed in the seeds will be lifted up and moved to the dust hopper 28 with the air flow under the action of the airflow generated by the fan. The dust hopper 28 is on the upper surface of the cover plate 1 and can effectively capture the generated dust and light impurities. The dust and impurities sucked into the dust hopper 28 are transported to the centrifugal fan 22 through the air duct 32 and the connecting pipe 31 under the negative pressure suction of the fan. Then, through the connecting pipe 27, these dust and impurities are discharged into the dust bag 8 for collection. The dust bag 8 has a certain filtering performance, which can prevent dust and impurities from escaping again, ensuring the cleanliness of the internal working environment of the cleaning machine.

[0025] The dust collection mechanism can perform real-time dust collection during the seed cleaning process, and promptly remove dust generated by the screening operation and light impurities mixed in the seeds. This allows the cleaning machine to always maintain a relatively clean working environment, reducing the interference of dust and impurities on the subsequent screening process. If weeds, branches, leaves, bran and other impurities mixed in the seeds are not removed in time, the purity and quality of the seeds will be reduced, affecting the subsequent sowing and planting effects. The dust collection mechanism can separate and collect these impurities in time during the cleaning process, solving the problem of impurities mixed in the seeds and improving the quality of the seeds.

[0026] Please see attached Figure 1 , Attachment Figure 3 The conveying device includes a material guide pipe 18, the bottom end of the material guide pipe 18 is located above the feed hopper 21, a shell 17 is arranged at the top of the material guide pipe 18, a motor 19 is arranged at one end of the shell 17, a rotating shaft 29 is fixedly arranged at the output end of the motor 19, the rotating shaft 29 is arranged inside the shell 17, an auger blade 30 is arranged on the outer wall of the rotating shaft 29, a feed hopper 16 is arranged on the outer wall of the shell 17, a bracket 13 is arranged in the middle of the outer wall of the shell 17, a universal wheel 12 is arranged at the bottom end of the bracket 13, a bracket 2 15 is arranged at the bottom end of the outer wall of the shell 17, and a universal wheel 2 14 is arranged at the bottom end of the bracket 2 15.

[0027] Specifically, when the motor 19 is started, it drives the shaft 29 to rotate, and then the auger blades 30 on the outer wall of the shaft 29 rotate accordingly, and the seeds placed in the feed hopper 16 enter the shell 17 under the action of gravity. The rotation of the auger blades 30 will push the seeds along the guide tube 18 to the feed hopper 21. Due to the spiral structure of the auger blades 30, the seeds in the shell 17 will be continuously pushed forward step by step during the rotation process, so as to achieve stable seed transportation, and the seed transportation speed and flow rate can be controlled, and the speed of the motor 19 can be adjusted to meet different cleaning requirements. The universal wheel 12 at the bottom of the bracket 13 and the universal wheel 2 14 at the bottom of the bracket 2 15 provide flexible mobility for the entire conveying device. The operator can easily push the conveying device and adjust its position according to the layout of the cleaning machine and actual work requirements.

[0028] The spiral conveying method of the auger blade 30 can continuously and stably convey the seeds from the feed hopper 1 16 to the feed hopper 2 21, avoiding the accumulation and blockage of seeds during the conveying process, improving the seed conveying efficiency, and ensuring that the cleaning machine can continuously obtain a stable supply of seeds, thereby improving the working efficiency of the entire cleaning process. The spiral conveying structure of the conveying device can solve the problems of blockage and stagnation in the conveying process caused by factors such as the shape and humidity of the seeds, ensuring that the seeds smoothly enter the cleaning machine, and solving the problem of poor seed conveying.

[0029] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 The vibration assembly includes two fixed seats 35, the top of the fixed seat 35 is fixedly set on the bottom of the base plate 37, the middle of the fixed seat 35 is rotatably connected with a second rotating shaft 36, eccentric blocks 34 are set on both sides of the middle of the second rotating shaft 36, and one end of the second rotating shaft 36 is fixedly set with a second motor 24.

[0030] Specifically, when the motor 24 is started, it drives the rotating shaft 2 36 to rotate. Since the eccentric blocks 34 are arranged on both sides of the middle of the rotating shaft 2 36, when the eccentric blocks 34 rotate at high speed with the rotating shaft 2 36, centrifugal force will be generated, and the direction of this centrifugal force is constantly changing, so that the fixed seat 35 and the bottom plate 37 connected thereto are subjected to periodic force, thereby generating vibrations in the up and down and left and right directions. This vibration is transmitted to the screen 1 20, the screen 2 23 and the screen 3 38 through the fixed column 26, so that the entire screening system is in a vibrating state. The change of the centrifugal force size and frequency directly affects the amplitude and frequency of the vibration. The operator can distinguish the actual screening conditions according to the size, shape, humidity, etc. of the seeds, and adjust the speed of the motor 2 24 to achieve the best vibration effect.

[0031] Vibration makes the seeds bounce repeatedly on the screen, which can quickly make the seeds pass through the screen holes or move the impurities on the screen to the corresponding discharge position, greatly improving the screening speed and efficiency. It can process a large number of seeds in a short time and meet the needs of large-scale seed cleaning. Traditional screening methods often have the problem of slow screening speed and cannot meet the requirements of modern agricultural production for seed cleaning efficiency. The vibration of the vibration component greatly improves the screening efficiency and solves the problem of low screening efficiency.
