Abstract
Description
Technical Field
[0001] The present application relates to the technical field of agricultural machinery, and in particular to a magnetic separation type melon seed worm eye machine. Background Art
[0002] Melon seeds, a general term for the seeds of melons and fruits, come in many varieties, including sunflower seeds, hanging melon seeds, watermelon seeds, pumpkin seeds, cucumber seeds, and loofah seeds. Melon seeds themselves are highly nutritious, boasting exceptional vitamin, protein, and oil content. Melon seeds are nutritious and have an alluring aroma. Watermelon seeds can strengthen the stomach, benefit the lungs, and moisten the intestines; sunflower seeds are rich in fatty acids and vitamin E; pumpkin seeds have an insect repellent effect. Eating a moderate amount of melon seeds can stimulate the taste nerves on the tongue, promote saliva and gastric juice secretion, aid digestion, and promote health. They can also stimulate facial muscle function.
[0003] When processing sunflower seeds, they need to be screened to effectively separate good seeds from those with worm holes. This process is typically performed using a magnetic separator. A magnetic material is mixed with the seeds, allowing the material to enter some of the seeds, imparting magnetic properties. The magnetic separator generates a magnetic field, which magnetizes the magnetic material. This magnetic force then separates the magnetic material from the seeds, effectively removing them.
[0004] In the prior art, melon seeds and iron powder are usually only stirred and mixed before magnetic separation. This not only results in insufficient mixing of some worm-hole melon seeds with the iron powder, reducing the removal rate of worm-hole melon seeds, but also causes greater power consumption during the stirring process.

[0014] Optionally, a vibration motor is provided at the bottom of the screen.
[0015] The magnetic separation type melon seed worm hole machine provided in this application realizes the efficient removal of worm hole melon seeds and has the following beneficial effects compared with the existing technology:
[0016] (1) Melon seeds and iron powder are mixed by using a venturi mixing tube. Since the melon seeds and iron powder have a certain speed after entering the contraction section and move in different directions, the iron powder and melon seeds are mixed while moving after entering the contraction section. This not only improves the degree of mixing between the iron powder and the melon seeds, but also enables the iron powder to fully enter the worm holes and cracked melon seeds. In this way, in the subsequent magnetic separation process, the force generated by the worm holes and cracked melon seeds and the magnetic source is stronger, and the separation efficiency of the worm hole melon seeds is also greatly improved. At the same time, compared with the use of a stirring mechanism, it saves more electricity and reduces costs.
[0017] (2) By setting up a magnetic separation structure, the magnetic source interacts with the iron powder, and the iron powder and the worm holes and cracked melon seeds containing iron powder are sucked out, thereby achieving the purpose of separating the worm holes and cracked melon seeds from the intact melon seeds. The magnetic separation structure includes a first motor, a rotating shaft, a barrel-shaped magnet, and a scraper. When the mixture of melon seeds and iron powder enters the shell and falls parabolically, the barrel-shaped magnet sucks the worm holes and cracked melon seeds containing iron powder and the iron powder to the surface of the barrel-shaped magnet. The scraper scrapes them to the worm hole area and discharges them from the first outlet. The intact melon seeds without iron powder fall to the finished product area under the action of gravity and are discharged from the second outlet. In this way, the worm hole melon seeds are screened out, and the screening efficiency of the worm hole melon seeds is improved.
[0018] (3) The worm-eye melon seeds are squeezed and crushed by two matching grinding rollers to expose the iron powder inside. The broken shells of the worm-eye melon seeds are completely separated from the iron powder by setting a screen, thereby maximizing the recovery rate of the iron powder.
[0019] (4) By setting up a spiral pusher, the iron powder and melon seeds mixed in the Venturi mixing tube are pushed into the shell for magnetic separation, and the mixing degree of melon seeds and iron powder is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.
[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides a magnetic separation type melon seed worm hole machine, including: a shell 1, a mixed feeding structure 2 and a magnetic separation structure 3.
[0032] The discharge end of the mixing and feeding structure 2 extends into the upper part of the shell 1. The mixing and feeding structure 2 includes a Venturi mixing tube and a feed port 220. The Venturi mixing tube includes a melon seed inlet section 211, a contraction section 212, an iron powder suction section 213, a throat section 214 and a diffusion section 215. The melon seed inlet section 211, the contraction section 212, the throat section 214 and the diffusion section 215 are connected in series in sequence. The outlet end of the iron powder suction section 213 is connected to the side wall of the contraction section 212, and the outlet end of the diffusion section 215 is connected to the feed port 220.
[0033] The magnetic separation structure 3 is located inside the shell 1, and the magnetic separation structure 3 is located on the lower side of the connection between the mixed feed structure 2 and the shell 1. A partition plate 350 is arranged between the mixed feed structure 2 and the magnetic separation structure 3, and the interior of the shell 1 is divided into an insect hole area 110 and a finished product area 120. The insect hole area 110 is provided with a first outlet 111, and the finished product area 120 is provided with a second outlet 121.
[0034] Specifically, the magnetic separation machine for removing wormholes from melon seeds works by mixing melon seeds with a magnetic substance (such as iron powder). The magnetic substance then enters the cracked and wormhole-infested melon seeds, making them magnetic. The melon seeds mixed with the magnetic substance are then transported to a magnetic source. The source generates a magnetic field, which magnetizes the magnetic substance and generates a magnetic force. This magnetic force separates the magnetic substance from the melon seeds, simultaneously removing any wormholes or cracked seeds, ultimately achieving the desired melon seed selection process.
[0035] In the present application, the mixing feeding structure 2 is used to mix the melon seeds and the iron powder and then transport them to the inside of the shell 1 for magnetic separation. The mixing feeding structure 2 includes a venturi mixing tube and a feed port 220. The venturi mixing tube includes a melon seed inlet section 211, a contraction section 212, an iron powder suction section 213, a throat section 214 and a diffusion section 215. The melon seeds are transported to the venturi mixing tube from the melon seed inlet section 211. When the melon seeds and air mixture enters the contraction section 212 from the melon seed inlet section 211, it has a certain speed and will generate a negative pressure area in the contraction section 212. The inlet end of the iron powder suction section 213 is connected to an iron powder storage tank. The negative pressure generated by the contraction section 212 will The iron powder is sucked into the contraction section 212. Since the melon seeds and iron powder have a certain speed after entering the contraction section 212 and move in different directions, the iron powder and melon seeds are mixed after entering the contraction section 212. In this way, the two are mixed while moving, which not only improves the degree of mixing between the iron powder and the melon seeds, but also allows the iron powder to fully enter the worm holes and cracked melon seeds. In this way, during the subsequent magnetic separation process, the force generated by the worm holes, cracked melon seeds and the magnetic source is stronger, and the separation efficiency of the worm hole melon seeds is greatly improved. The melon seeds and iron powder mixed in the contraction section 212 continue to move into the throat section 214 for further mixing, and finally move to the feed port 220 through the diffusion section 215, and then are sent to the shell 1 through the feed port 220 for magnetic separation. Using a venturi mixing tube to mix the melon seeds and iron powder is more energy-saving than using a stirring mechanism, thereby reducing costs.
[0036] Among them, the partition plate 350 is located between the mixed feeding structure 2 and the magnetic separation structure 3, and divides the interior of the shell 1 into an insect-hole area 110 and a finished product area 120. The height of the partition plate 350 is equal to or lower than the height of the magnetic source, which avoids the partition plate 350 being too high and blocking the magnetic source's attraction to the iron powder, and can also separate insect-hole melon seeds from complete melon seeds. The magnetic separation structure 3 is located on the lower side of the connection between the mixed feeding structure 2 and the shell 1 in the shell 1, so that the mixture of melon seeds and iron powder is easily attracted by the magnetic source during the process of falling under gravity, thereby improving the screening effect of insect-hole melon seeds.
[0037] The present application realizes the efficient screening of worm-hole melon seeds through the above scheme. By using the venturi mixing tube to mix the melon seeds and iron powder, since the melon seeds and iron powder have a certain speed after entering the contraction section and move in different directions, the iron powder and melon seeds are mixed while moving after entering the contraction section, which not only improves the degree of mixing of the iron powder and melon seeds, but also enables the iron powder to fully enter the worm holes and cracked melon seeds. In this way, in the subsequent magnetic separation process, the force generated by the worm holes and cracked melon seeds and the magnetic source is stronger, and the separation efficiency of the worm holes and melon seeds is greatly improved. At the same time, it saves more electricity than the stirring mechanism, thereby reducing costs. By setting up a magnetic separation structure, the magnetic source and the iron powder interact, and the iron powder and the worm holes and cracked melon seeds containing iron powder are sucked out, so as to achieve the purpose of separating the worm holes and cracked melon seeds from the intact melon seeds. The magnetic separation structure includes a first motor, a rotating shaft, a barrel-shaped magnet, a scraper, and a separator. When a mixture of melon seeds and iron powder enters the housing and falls parabolically, the barrel-shaped magnet attracts the insect-hole and cracked melon seeds containing iron powder to the surface of the barrel-shaped magnet. The scraper then scrapes them into the insect-hole area and discharges them through the first outlet. Intact melon seeds, free of iron powder, fall under gravity to the finished product area and are discharged through the second outlet, thus removing the insect-hole melon seeds. This arrangement improves the efficiency of removing insect-hole melon seeds.
[0038] Optionally, the angle between the iron powder suction section 213 and the melon seed inlet section 211 is 40-90°.
[0039] Specifically, this allows the iron powder to be more smoothly sucked into the contraction section 212 and mixed with the melon seeds, thereby improving the degree of mixing between the melon seeds and the iron powder, helping to increase the force of the subsequent barrel magnet 330 on the iron powder, and further helping to screen out worm-eyed melon seeds.
[0040] like Figure 4 、 Figure 5 As shown, optionally, a screw pusher is provided inside the feed port 220, and the screw pusher includes a screw 221 and a second motor 222. The second motor 222 is provided outside the feed port 220 at one end away from the shell 1, and one end of the screw 221 is connected to the output end of the second motor 222. One end of the screw 221 extends into the feed port 220 and is rotatably connected to the second fixed rod 223 through a bearing.
[0041] Specifically, the iron powder and melon seeds mixed in the venturi mixing tube enter the feed port 220, and are powered by the second motor 222 to drive the screw 221 to rotate. The propeller on the screw 221 acts on the melon seeds and iron powder inside while rotating, so that the iron powder and melon seeds are further mixed while moving forward, thereby improving the degree of mixing of the melon seeds and iron powder, and at the same time, the mixture of melon seeds and iron powder is transported to the inside of the shell 1 for magnetic separation.
[0042] Among them, the two ends of the second fixed rod 223 are connected to the inner wall of the feed port 220, and the bearing is set at the center of the second fixed rod 223 and is coaxial with the screw 221, so that the screw 221 does not deviate when rotating, which is conducive to the stable operation of the screw pusher.
[0043] The magnetic separation structure 3 includes a first motor 310, a rotating shaft 320, a barrel-shaped magnet 330, and a scraper 340. The first motor 310 is disposed outside the housing 1, and the output end of the first motor 310 is connected to one end of the rotating shaft 320. The other end of the rotating shaft 320 extends into the housing 1 and is connected to a positioning plate 321 connected to the inner wall of the housing 1 via a bearing. The barrel-shaped magnet 330 is coaxially arranged with the rotating shaft 320 via a connecting rod 331. The scraper 340 is connected to the inner wall of the housing 1 via a first fixing rod 341. One side of the scraper 340 in the longitudinal direction is parallel to the axial direction of the barrel-shaped magnet 330 and abuts the outer wall of the barrel-shaped magnet 330.
[0044] Specifically, the magnetic separation structure 3 is used to make the magnetic source interact with the iron powder, suck out the iron powder and the worm holes and cracked melon seeds containing iron powder inside, so as to achieve the purpose of separating the worm holes and cracked melon seeds from the intact melon seeds. The magnetic separation structure 3 includes a first motor 310, a rotating shaft 320, a barrel-shaped magnet 330, and a scraper 340. The output end of the first motor 310 is connected to one end of the rotating shaft 320. The first motor 310 provides power to drive the rotating shaft 320 to rotate. The barrel-shaped magnet 330 is coaxially arranged with the rotating shaft 320 through a connecting rod 331. The barrel-shaped magnet 330 is sleeved on the outside of the rotating shaft 320. When the rotating shaft 320 rotates, the barrel-shaped magnet 330 also rotates. When the barrel-shaped magnet 330 rotates, the mixture of melon seeds and iron powder enters the shell 1 from the feed port 220 and performs parabolic motion. During the falling process of the melon seeds and iron powder, the barrel-shaped magnet 330 generates a magnetic field, which sucks out the worm holes and cracked melon seeds containing iron powder inside. , cracked melon seeds and iron powder are sucked onto the surface of the barrel-shaped magnet 330. Since the barrel-shaped magnet 330 is in a continuous rotating state, and one side of the scraper 340 in the longitudinal direction is parallel to the axial direction of the barrel-shaped magnet 330 and abuts against the outer wall of the barrel-shaped magnet 330, when the worm eyes, cracked melon seeds and iron powder containing iron powder sucked onto the surface of the barrel-shaped magnet 330 rotate to the scraper 340, the scraper 340 scrapes the worm eyes, cracked melon seeds and iron powder containing iron powder into the worm eye area 110 and discharges them from the first outlet 111. The complete melon seeds without iron powder inside fall to the finished product area 120 under the action of gravity and are discharged from the second outlet 121, thereby achieving the screening of worm-eye melon seeds.
[0045] The end of the rotating shaft 320 away from the first motor 310 extends into the housing 1. A positioning plate 321 is connected to the inner wall of the housing 1. The positioning plate 321 has a through hole. A bearing is provided in the through hole for the rotating shaft 320 to pass through. This serves to limit and stabilize the rotating shaft 320, preventing the rotating shaft 230 from shaking due to unstable direction during rotation, thereby contributing to the stable operation of the magnetic separation structure 3. The scraper 340 is connected to the inner wall of the housing 1 via a first fixing rod 341. The provision of the first fixing rod 341 facilitates the scraper 340 to maintain a stable contact with the outer wall of the barrel-shaped magnet 330, thereby promptly scraping off insect holes, cracked melon seeds, and iron powder containing iron powder on the surface of the barrel-shaped magnet 330, thereby maintaining the magnetic properties of the barrel-shaped magnet 330.
[0046] Furthermore, the scraper 340 is located directly below the barrel-shaped magnet 330 to facilitate the falling of insect holes, cracked melon seeds and iron powder containing iron powder.
[0047] like Figure 5 、 Figure 6 and Figure 7 As shown, optionally, a crushing box 410 is provided in the wormhole area 110 directly below the barrel-shaped magnet 330. The crushing box 410 is a hollow structure that passes through from top to bottom. Two matching grinding rollers 420 are rotated inside the crushing box 410. A third motor 430 is provided outside the crushing box 410. The output end of the third motor 430 is connected to one of the grinding rollers 420, and the two grinding rollers 420 are meshed and connected via a gear 440.
[0048] Specifically, the wormhole area 110 contains iron powder and wormholes and cracked melon seeds containing iron powder, and the iron powder therein can be recycled and reused. However, iron powder inevitably remains inside the wormholes and cracked melon seeds, resulting in a low iron powder recovery rate and a large amount of iron powder waste. Therefore, the wormholes and cracked melon seeds containing iron powder are crushed to completely separate the iron powder inside from the melon seeds, thereby maximizing the iron powder recovery rate. The crushing box 410 is used to provide a crushing space for the wormholes and cracked melon seeds containing iron powder. Two matching grinding rollers 420 squeeze and crush the wormhole melon seeds, exposing the iron powder inside. A third motor 430 is used to power the two grinding rollers 420, causing them to rotate. The output end of the third motor 430 is connected to one of the grinding rollers 420, and the two grinding rollers 420 are meshed and connected via a gear 440, so that the two grinding rollers 420 rotate in opposite directions, crushing the wormhole melon seeds and improving the iron powder recovery rate.
[0049] like Figure 7 As shown, optionally, a conical guide plate 450 is provided on the top of the crushing box 410 .
[0050] Specifically, the guide plate 450 serves to guide the iron powder scraped off the barrel-shaped magnet 330 and the worm-hole melon seeds containing iron powder. The lower conical part of the conical guide plate 450 is located directly below the barrel-shaped magnet 330, and the adjacent parts of the two grinding rollers 420 are also located directly below the conical guide plate 450, so that the worm-hole melon seeds containing iron powder fall between the two grinding rollers 420, thereby improving the crushing efficiency of the two grinding rollers 420 on the worm-hole melon seeds, and thereby improving the recovery rate of iron powder.
[0051] like Figure 6 As shown, optionally, a screen 5 is obliquely arranged below the crushing box 410, the outer side of the screen 5 is connected to the inner wall of the shell 1 and the partition plate 350, the screen 5 is inclined downward along the direction from the partition plate 350 to the first outlet 111, and a third outlet 123 is provided at the lower end connection between the shell 1 and the screen 5.
[0052] Specifically, screen 5 is used to separate the worm-hole melon seed shells and iron powder obtained after crushing. After screening, the worm-hole melon seed shells are located on the upper surface of screen 5 and discharged through third outlet 123. The iron powder passes through the mesh of screen 5 and falls to the bottom of worm-hole area 110 and is discharged through first outlet 111, achieving efficient recovery of iron powder. Screen 5 is tilted to facilitate the discharge of the worm-hole melon seed shells through third outlet 123.
[0053] like Figure 7 As shown, optionally, a vibration motor 6 is provided at the bottom of the screen 5 .
[0054] Specifically, the vibration motor 6 vibrates the screen 5, which can not only accelerate the screening of worm-hole melon seed shells and iron powder, but also enable the worm-hole melon seed shells to move quickly to the third outlet 123 for discharge, which is beneficial to the separation of iron powder and melon seed shells, and improves the working efficiency of the magnetic separation melon seed worm-hole machine.
[0055] The technical solution of this application is described in detail below with reference to specific embodiments.
[0056] The operation process of the magnetic separation type melon seed worm hole machine in this embodiment is as follows:
[0057] Mixed feeding: Melon seeds are transported to the Venturi mixing tube from the melon seed inlet section 211. The melon seed and air mixture has a certain speed when entering the contraction section 212 from the melon seed inlet section 211, creating a negative pressure zone in the contraction section 212. The negative pressure generated by the contraction section 212 draws iron powder from the inlet end of the iron powder suction section 213 into the contraction section 212. After entering the contraction section 212, the iron powder mixes with the melon seeds, and the iron powder fully enters the insect holes and cracked melon seeds. The melon seeds and iron powder continue to move into the throat section 214 for further mixing, and finally move through the diffusion section 215 to the feed port 220. The second motor 222 is turned on to drive the screw 221 to rotate. The propeller on the screw 221 rotates and pushes the melon seeds and iron powder inside forward, further mixing them. The mixture of melon seeds and iron powder is transported to the interior of the shell 1 for magnetic separation.
[0058] Magnetic separation: Turn on the first motor 310 to drive the rotating shaft 320 to rotate, and drive the barrel-shaped magnet 330 to rotate. At the same time, the mixture of melon seeds and iron powder enters the shell 1 from the feed port 220 and performs parabolic motion. During the falling process of the melon seeds and iron powder, the barrel-shaped magnet 330 generates a magnetic field, which sucks the worm eyes, cracked melon seeds and iron powder containing iron powder inside to the surface of the barrel-shaped magnet 330. When the barrel-shaped magnet 330 rotates to the scraper 340, the scraper 340 scrapes the worm eyes, cracked melon seeds and iron powder containing iron powder into the worm eye area 110, and the complete melon seeds without iron powder inside fall to the finished product area 120 under the action of gravity and are discharged from the second outlet 121.
[0059] Iron Powder Recovery: The third motor 430 is activated to power the grinding rollers 420. Wormhole-shaped and cracked melon seeds containing iron powder fall through the conical guide plate 450 onto the two matching grinding rollers 420, where they are crushed and exposed to the iron powder. The resulting wormhole-shaped melon seed shells and iron powder pass through the screen 5. The vibration motor 6 is activated periodically, and the wormhole-shaped melon seed shells remain on the upper surface of the screen 5 and are discharged through the third outlet 123. The iron powder passes through the mesh of the screen 5 and falls to the bottom of the wormhole area 110, where it is discharged through the first outlet 111. This achieves the separation of wormhole-shaped melon seeds and the efficient recovery of iron powder.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
