Description

Technical Field

[0001] The invention relates to the technical field of seed impurity removal equipment, in particular to a ramie seed processor with an impurity removal function. Background Art

[0002] Ramie is a hemp plant with high economic value. Its fiber is widely used in the textile and papermaking industries, especially in agriculture in China and Japan. Ramie has a long history of cultivation. With the development of modern agricultural science and technology, its planting and processing techniques are constantly optimized. For example, through breeding technology, more high-yield and disease-resistant ramie varieties are selected, and modern cultivation techniques such as reasonable crop rotation, fertilization and irrigation are adopted. These measures have effectively improved the yield and quality of ramie. At the same time, the introduction of mechanized processing technology has also improved the production efficiency and product consistency of ramie fiber. Ramie seeds, as the main way of its reproduction, are small in shape, brown and smooth, with good germination characteristics, and require suitable soil and climatic conditions to grow smoothly. In addition to being an economic crop, ramie also plays a positive role in improving soil quality and promoting biodiversity, demonstrating its important value in ecological agriculture.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0039] Example 1: Please refer to Figures 1 to 6 In an embodiment of the present invention, a ramie seed processor with a de-impurity function includes a wind screen assembly 1, which includes a screening box 101. A positive pressure air duct 102 is plugged and fixed to the left wall of the screening box 101. A feed pipe 103 is fixedly connected to the positive pressure air duct 102. The feed pipe 103 passes through the upper side wall of the screening box 101 and is fixedly connected to a cone bucket. The positive pressure air duct 102 is connected and fixed with the feed pipe 103. The positive pressure air duct 102 is fixedly connected with an inclined A hopper 104 is provided, and the hopper 104 is located just below the feed pipe 103. The hopper 104 can be a sieve structure. How can the wind force be used to enable the seeds to better enter the drum 106? A fixed round block 105 is fixedly connected to the positive pressure air duct 102. The side wall of the fixed round block 105 is rotatably connected to the drum 106 through a bearing. The inner side wall of the drum 106 is fixedly connected to a plurality of evenly distributed advancing inclined plates 107. The plurality of advancing inclined plates 107 are inclined. In the process of the rotation of the drum 106, when the propulsion inclined plate 107 rotates to one side of the drum 106, the seeds will roll under their own gravity according to the tilted state of the propulsion inclined plate 107, thereby achieving the purpose of moving the seeds. After the drum 106 rolls for multiple turns, the seeds will gradually move until they fall from the outlet end of the drum 106. The upper inner wall and the front and rear inner walls of the screening box 101 are fixedly connected with a fixed ring block 108 by welding, and the fixed ring block 108 is rotatably connected to the drum 106. A driving gear 109 is rotatably connected to the side wall of the fixed ring block 108. A tooth surface 110 is fixedly connected to the side wall of the drum 106, and the tooth surface 110 is meshed with the driving gear 109. A motor 111 is fixedly connected to the fixed ring block 108, and the output end of the motor 111 is fixedly connected to the driving gear 109. A fan 2 is fixedly connected to the upper side wall of the screening box 101, and the air outlet end of the fan 2 is connected to the positive pressure air duct 102.

[0040] When the fan 2 is started, the air inside the screening box 101 enters through the backblowing anti-blocking component 4, and is discharged back to the screening box 101 through the positive pressure air duct 102 to realize air circulation. When the motor 111 is started, the motor 111 drives the drum 106 to rotate by engaging the driving gear 109 with the tooth surface 110. When the seeds enter from the cone bucket, the seeds will fall into the hopper 104, and then under the action of the wind force and the weight of the seeds themselves, the seeds fall into the drum 106. Through the rotation of the drum 106, the propulsion inclined plate 107 can throw the seeds up. In the process of throwing the seeds up, the wind force generated by the fan 2 can blow the seeds, and the lighter impurities and dust are directly separated from the seeds under the wind force. This repeated throwing method can also promote the separation of impurities with strong adhesion from the seeds.

[0041] It is worth noting that the roller 106 can only throw the seeds up when it is at a certain rotation speed. This principle is similar to that of a ball mill. The rotation speed can be set by installing a camera at the fixed round block 105 and observing the throwing state of the seeds. The rotation speed can also be factory-set according to the characteristics of the seeds. The specific rotation speed setting method is a prior art and will not be described here.

[0042] An interception component 3 for preventing impurities from accumulating is fixedly connected inside the screening box 101, and the interception component 3 is located on one side of the drum 106. A backblowing anti-blocking component 4 for cleaning dust is fixedly connected to the air inlet of the fan 2. A dust collecting component 5 for collecting dust is magnetically connected to the side wall of the screening box 101. During the startup of the fan 2, dust and impurities enter the interception box 301 through the interception of the interception component 3. The interception component 3 can prevent more seeds from being thrown into the interception box 301 by the drum 106. After the impurities and dust enter the interception box 301, most of the relatively heavy impurities will directly fall to the bottom of the interception box 301, and the tiny impurities and dust floating in the air will be adsorbed and filtered by the backblowing anti-blocking component 4, and then backblown into the dust collecting component 5 to avoid blockage and affect the airflow size.

[0043] A vibrating screen 112 is fixedly connected to the lower inner wall of the screening box 101, a debris discharge port 113 is bored on the lower side wall of the screening box 101 and a seed discharge port 114 is bored on the lower side wall of the screening box 101 and is located on the lower side of the vibrating screen 112. After the seeds come out from one end of the drum 106, they will directly fall to the upper side of the vibrating screen 112 and be screened twice by the vibration of the vibrating screen 112. This process can screen out larger and heavier impurity particles and discharge them from the debris discharge port 113, while the seeds will pass through the vibrating screen 112 and fall from the seed discharge port 114.

[0044] The interception assembly 3 includes an interception box 301 fixedly connected to the inside of the screening box 101, a negative pressure square tube 302 is connected to the side wall of the interception box 301, and an interception cover 303 is connected to the end of the negative pressure square tube 302 away from the interception box 301, and a cross-rotating dust net 304 is rotatably connected to the inside of the interception cover 303, and a first leather gear 305 is rotatably connected to the upper end of the interception cover 303, and the first leather gear 305 is fixedly connected to the cross-rotating dust net 304, and the first leather gear 305 is fixedly connected to the side wall of the first leather gear 305. The driving gear 1 A second bevel gear 307 is fixedly connected to the side wall of 09, and the second bevel gear 307 is meshed with the first bevel gear 306. A semicircular screen plate 308 is fixedly connected to the lower end of the interception cover 303. During the rotation of the driving gear 109, the driving gear 109 also drives the second bevel gear 307 to rotate. At this time, the second bevel gear 307 drives the first skin gear 305 to rotate by meshing with the first bevel gear 306. When the first skin gear 305 rotates, it can not only drive the cross rotating dust screen 304 to rotate, but also drive the backblowing anti-blocking component 4 to rotate.

[0045] When impurities approach the cross-rotating dust net 304, they will quickly stick to the surface of the rotating cross-rotating dust net 304 under the negative pressure of the fan 2. Smaller impurities will directly pass through the cross-rotating dust net 304 and enter the interception box 301, while larger impurities will stick to the surface of the cross-rotating dust net 304. As the cross-rotating dust net 304 rotates, after larger impurities enter the negative pressure square tube 302, they will also enter the interception box 301 through the negative pressure. When seeds are thrown onto the surface of the cross-rotating dust net 304, the seeds themselves are not affected by the wind and fall directly. During this period, some seeds may be pushed into the interception cover 303 by the rotation of the cross-rotating dust net 304. However, through the setting of the semicircular sieve plate 308, the seeds can also fall from the semicircular sieve plate 308.

[0046] Example 2: Please refer to Figures 5 to 10Based on Example 1, the backblowing anti-blocking component 4 includes an air inlet pipe 401 rotatably connected to the air inlet of the fan 2 through a mechanical seal, and the air inlet pipe 401 is rotatably connected to the upper side wall of the interception box 301, a second leather gear 402 is fixedly connected to the air inlet pipe 401, a leather gear belt 403 is sleeved between the second leather gear 402 and the first leather gear 305, the lower end of the air inlet pipe 401 is connected to a multi-port cylinder 404, a plurality of dustproof nets 405 are fixedly connected to the side wall of the multi-port cylinder 404, an air distribution pipe 406 is rotatably connected to the lower side wall of the multi-port cylinder 404, the upper end of the air distribution pipe 406 is connected to a hollow box 407, and the end of the air distribution pipe 406 away from the multi-port cylinder 404 passes through the interception box. The interception box 301 is connected to the positive pressure air duct 102, and a sealing cover 408 is fixedly connected to the side wall of the interception box 301, and the sealing cover 408 is set through the screening box 101. Dust discharge ports 409 are opened on the hollow box 407 and the sealing cover 408. The tiny impurities and dust floating inside the interception box 301 are attached to the surface of the dustproof net 405. When the first leather gear 305 rotates, it can also drive the multi-mouth cylinder 404 to rotate through the leather tooth belt 403. During the startup of the fan 2, part of the blown wind force is distributed to the hollow box 407 through the air distribution pipe 406, so that the hollow box 407 can blow the dustproof net 405, so that the impurities and dust on the surface are blown into the dust collecting component 5.

[0047] It is worth noting that multiple circles of sealing rings are fixedly connected to the side wall of the hollow box 407 to prevent the wind blown out of the hollow box 407 from entering the multi-port cylinder 404. The arrangement of the sealing rings is prior art and will not be repeated here.

[0048] The dust collecting component 5 includes a dust box 501, to which a magnetic frame 502 is fixedly connected, and the magnetic frame 502 is magnetically attracted to the screening box 101, and a filter screen 503 is fixedly connected to the side wall of the dust box 501. After dust enters the dust box 501, the staff can directly remove the dust box 501 for cleaning in their spare time.

[0049] The working principle of the present invention is:

[0050] When the present invention is used, first, the staff starts the fan 2 and the motor 111. When the fan 2 is started, the air inside the screening box 101 enters through the back-blowing anti-blocking component 4, and is discharged back to the screening box 101 through the positive pressure air duct 102, so as to realize the circulation of air. The air flow can be referred to Fig.10 , then the seeds are put into the cone bucket at the upper end of the feed pipe 103. At this time, the seeds will fall into the drum 106 along the propulsion inclined plate 107. When the motor 111 is started, the motor 111 drives the drum 106 to rotate through the meshing of the driving gear 109 and the tooth surface 110, so that the propulsion inclined plate 107 can throw the seeds up. The throwing state of the seeds can be referred to Fig. 9In the process of throwing the seeds, the wind force generated by the fan 2 can blow the seeds through the positive pressure air duct 102, and the lighter impurities and dust are directly separated from the seeds under the wind force and move toward the interception component 3. At the same time, this repeated throwing method can also promote the separation of impurities with strong adhesion from the seeds;

[0051] When impurities approach the cross-rotating dust net 304, smaller impurities will directly pass through the cross-rotating dust net 304 and enter the interception box 301 under the negative pressure generated by the fan 2, while larger impurities will be intercepted and stick to the surface of the cross-rotating dust net 304. As the cross-rotating dust net 304 rotates, after larger impurities enter the negative pressure square tube 302, they will also enter the interception box 301 through the negative pressure. Since there is a certain distance between the backblowing anti-blocking component 4 and the negative pressure square tube 302, the larger impurities will fall to the bottom of the interception box 301. After the drum 106 rolls for many circles, the seeds will be repeatedly thrown up and will also be pushed toward the outlet of the drum 106 through the pusher inclined plate 107. The mouth end moves and falls, and when the seeds are thrown onto the surface of the cross-rotating dust net 304, the seeds fall directly because they are not affected by the wind. During this period, some seeds may be rotated and pushed into the interception cover 303 by the cross-rotating dust net 304. However, the semicircular screen plate 308 is arranged at the bottom of the interception cover 303, so that the seeds can also pass through the semicircular screen plate 308 and fall. Then the fallen seeds will fall directly to the upper side of the vibrating screen 112, and the vibration of the vibrating screen 112 will perform secondary screening. This process can screen out larger and heavier impurity particles, so that they are discharged from the impurity discharge port 113, and the seeds are passed through the vibrating screen 112 and fall from the seed discharge port 114;

[0052] The tiny impurities and dust floating inside the interception box 301 are attached to the surface of the dustproof net 405 under the negative pressure of the fan 2. When the first leather gear 305 rotates, it can also drive the multi-mouth cylinder 404 to rotate through the leather tooth belt 403. During the startup of the fan 2, part of the blown wind force is distributed to the hollow box 407 through the air distribution pipe 406, so that the hollow box 407 can blow the dustproof net 405, so that the impurities and dust on the surface are blown into the dust collecting component 5, thereby avoiding clogging of the dustproof net 405.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
