Abstract
Description
Technical Field
[0001] This utility model relates to the field of winter melon seed removal machinery technology, specifically, to a winter melon pulp seed removal machine. Background Technology
[0002] Winter melon seeds are rich in protein, unsaturated fatty acids, vitamin C, vitamin E, potassium, magnesium, iron and other nutrients, so the seeds need to be separated during the processing of winter melon.
[0003] In existing technology, winter melon seed removers can crush the pulp containing seeds in a crushing chamber. The crushed pulp and seeds then enter a screen equipped with a screw conveyor to separate them. However, to ensure crushing quality, the winter melon pulp usually needs to be soaked for a day before threshing. This soaking process not only occupies a lot of space but also seriously affects threshing efficiency. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a winter melon pulp deseeding machine, which solves the technical problem that winter melon pulp needs to be soaked for a day to be completely deseeded in the prior art.
[0005] According to one aspect, at least one embodiment of the present invention provides a winter melon pulp and seed removal machine, comprising:
[0006] The frame has a feed inlet.
[0007] A sieve cylinder is installed on the frame. The top of the sieve cylinder has a feed inlet located below the feed port. The sieve holes of the sieve cylinder are larger than the melon seeds. The sieve cylinder is used to separate the melon seeds and the smaller melon pulp.
[0008] A rotating roller is rotatably mounted on the frame and located inside the sieve cylinder. The rotating roller is coaxial with the sieve cylinder and has a spiral conveying section and a striking section. The spiral conveying section is located below the feed inlet and is used to convey the pulp into the striking section.
[0009] A plurality of support rods are distributed at intervals along the axis of the rotating roller on the striking section. The support rods extend radially toward the inner wall of the sieve cylinder. A plurality of striking rods are distributed at intervals along the extension direction of the support rods. The length direction of the striking rods is parallel to the axis of the rotating roller. The striking rods are used to strike the pulp entering the striking section to separate the seeds from the pulp.
[0010] For example, in a winter melon pulp deseeding machine provided in at least one embodiment of the present invention, the front end of the striking rod has a cutting tip along the rotation direction of the rotating roller. The cutting tip is used to cut the pulp so as to expose the seeds located inside the pulp.
[0011] For example, in a winter melon pulp deseeding machine provided in at least one embodiment of the present invention, the bottom of the sieve cylinder away from the feed inlet has a discharge outlet, which is used to discharge melon pulp with a larger volume.
[0012] For example, in a winter melon pulp deseeding machine provided in at least one embodiment of the present invention, the beating section has a spiral baffle that abuts against the inner wall of the sieve cylinder. The spiral baffle is used to guide the pulp of the beating section to the discharge port, and the support rod is located within the interval of the spiral baffle.
[0013] For example, in a winter melon pulp deseeding machine provided in at least one embodiment of the present invention, the top of the support rod is also provided with a scraper, which abuts against the inner wall of the sieve cylinder so that the scraper can scrape off the adhesive on the inner wall of the sieve cylinder.
[0014] For example, in at least one embodiment of the present invention, a winter melon pulp deseeding machine is provided, wherein the frame has a melon seed outlet, and further includes:
[0015] A sieve is installed on the frame and located below the sieve cylinder. The sieve is used to catch melon seeds and pulp falling from the sieve cylinder. The sieve holes are smaller than the melon seeds so that the melon seeds remain on the sieve. The sieve is semi-circular.
[0016] A spiral conveyor rod is rotatably mounted on the frame. The spiral conveyor rod abuts against the inner wall of the screen and is used to guide the melon seeds on the screen to the melon seed outlet.
[0017] For example, in at least one embodiment of the present invention, a winter melon pulp deseeding machine further includes:
[0018] There are two guide baffles, both of which are set on the frame. The guide baffles are located on both sides of the screen cylinder in the horizontal direction. The guide baffles are used to guide the material falling from the screen holes of the screen cylinder to the screen mesh.
[0019] For example, in at least one embodiment of the present invention, a winter melon pulp deseeding machine further includes a shearing device. The shearing device is disposed on the frame and located between the discharge port and the screen. The shearing device is used to shear the melon pulp falling from the discharge port so that the pulp falls onto the screen with a volume smaller than that of the seeds. The shearing device includes:
[0020] The first rotating rod is connected to the driving component and has several spaced first shearing blocks along the axial direction of the first rotating rod.
[0021] The second rotating rod is connected to the first rotating rod in a driving manner. It has a plurality of second shearing blocks distributed at intervals along the axial direction of the second rotating rod. The first shearing blocks and the second shearing blocks are distributed alternately along the axial direction of the second rotating rod. The first shearing blocks and the second shearing blocks have overlapping portions along the radial direction of the second rotating rod. The first shearing blocks and the second shearing blocks are capable of shearing the pulp of the melon.
[0022] For example, in at least one embodiment of the present invention, a winter melon pulp deseeding machine further includes:
[0023] A plurality of water sprayers are provided on the frame, all located above the screen cylinder, and the plurality of water sprayers are spaced apart along the axial direction of the rotating roller. The water sprayers are configured to be connected to an external water pump, and the water sprayed by the water sprayers passes through the screen holes of the screen cylinder and falls into the inside of the screen cylinder, the shearing device, and the screen mesh in one go, so as to soften the pulp of the melon when it comes into contact with water.
[0024] For example, in a winter melon pulp deseeding machine provided in at least one embodiment of this utility model, the conveying direction of the spiral conveying rod is opposite to the conveying direction of the spiral conveying section.
[0025] The beneficial effects of the embodiments of this utility model are as follows:
[0026] In this invention, after the melon pulp is conveyed to the beating section of the rotating roller, the beating rod on the support rod continuously beats the pulp as the roller rotates. The high-speed impact of the beating rod breaks the pulp, weakening the connection between the seeds and the pulp, thus allowing the seeds to detach from the pulp. The detached seeds and some pulp fragments continue to fall through the sieve holes, completing the seed removal process. Compared to soaking before seed removal, mechanical beating better preserves the integrity and nutritional components of the seeds, improving seed quality and facilitating subsequent processing and utilization.

[0040] like Figures 1-5 As shown, it illustrates a winter melon pulp and seed removal machine according to one embodiment of the present invention, comprising:
[0041] The frame 100 provides stable support for components such as the sieve cylinder 200 and rotating roller 300. The feed inlet 110 is located at the top of the frame 100 and is rectangular or circular. The sieve cylinder 200 is cylindrical, and its top feed inlet 210 corresponds to the feed inlet 110 of the frame 100, ensuring that the pulp can fall directly into the sieve cylinder 200. The sieve holes on the sieve cylinder 200 are larger than the seeds, allowing seeds and smaller pulp to fall through while blocking larger pulp pieces for further processing. The sieve cylinder 200 is fixed to the frame 100 by welding or bolting to ensure a secure connection. When the pulp enters the sieve cylinder 200, the seeds and smaller pulp are sieved out through the sieve holes by the rotating roller 300, achieving initial separation and reducing the burden of subsequent processing.
[0042] The rotating roller 300 is rotatably mounted on the frame 100 via bearings at both ends, and is coaxial with the screen cylinder 200. The rotating roller 300 is divided into a spiral conveying section 310 and a striking section 320. The spiral conveying section 310 is located below the feed inlet 210, and its surface is provided with spiral blades. The rotating roller 300 conveys the pulp entering from the feed inlet 210 to the striking section 320 by rotating. Several support rods 400 are distributed at intervals along the axis of the rotating roller 300 on the striking section 320. The support rods 400 extend radially towards the inner wall of the screen cylinder 200 along the rotating roller 300. Several striking rods 410 are distributed at intervals on each support rod 400, and the length direction of the striking rods 410 is parallel to the axis of the rotating roller 300. The rotating roller 300 is driven to rotate by a motor via a belt or chain transmission mechanism. The screw conveyor section 310 is responsible for smoothly conveying the melon pulp entering the sieve cylinder 200 to the beating section 320, ensuring that the pulp can undergo further processing in an orderly manner. The rotating roller 300 drives the support rod 400 and the beating rod 410 to rotate. The beating rod 410 continuously beats and collides with the pulp, breaking down the connection structure between the pulp and the seeds, making it easier to separate the seeds from the pulp. Through this mechanical beating method, there is no need to soak the winter melon pulp for a long time, thus improving the seed removal efficiency.
[0043] Working principle: After the melon pulp is conveyed to the beating section 320 of the rotating roller 300, the beating rod 410 on the support rod 400 continuously beats the pulp as the rotating roller 300 rotates. The high-speed impact of the beating rod 410 breaks the pulp with external force, weakening the connection between the seeds and the pulp, thus allowing the seeds to detach from the pulp. The detached seeds and some pulp fragments continue to fall through the sieve holes, completing the seed removal process. Compared with soaking before seed removal, mechanical beating better preserves the integrity and nutritional components of the seeds, improving seed quality and facilitating subsequent processing and utilization.
[0044] In some examples, along the rotation direction of the rotating roller 300, the front end of the striking rod 410 is machined into a sharp cutting tip 411. The cutting tip 411 is shaped like a triangular pyramid. The cutting tip 411 can generate a concentrated cutting force during rotation, effectively cutting the pulp.
[0045] Working principle: When the rotating roller 300 drives the striking rod 410 to rotate, the cutting tip 411 first contacts the pulp. At high speed, the cutting tip 411 easily cuts into the pulp, exposing the seeds that were originally encased within. This not only helps the striking rod 410 to act more directly on the connection between the seeds and the pulp, promoting seed detachment, but also, for some thick pulp tightly encasing the seeds, the cutting tip 411 can preemptively disrupt the pulp structure, greatly improving seed removal efficiency. Compared to simple striking, this combination of cutting and striking allows for more comprehensive and thorough processing of the pulp, ensuring that the seeds are fully detached from all parts of the pulp.
[0046] In some examples, the discharge port 220 is located at the bottom of the sieve cylinder 200, away from the inlet 110. Its shape is typically rectangular or circular. During the seed removal process, the sieve holes of the sieve cylinder 200 block larger pieces of pulp, which gradually move towards the bottom of the sieve cylinder 200 under the action of the rotating roller 300. The discharge port 220 provides a discharge channel for these larger pieces of pulp, allowing them to leave the sieve cylinder 200 in a timely manner and preventing excessive accumulation within the sieve cylinder 200 that could affect the seed removal effect.
[0047] The melon pulp chunks that come off from the discharge port 220 can be manually refilled into the sieve cylinder 200 for secondary screening.
[0048] In some examples, a spiral baffle 321 is installed in the striking section 320 of the rotating roller 300. The spiral baffle 321 is in the shape of a continuous spiral, and its inner diameter is adapted to the outer diameter of the rotating roller 300, fitting tightly against the rotating roller 300. It is fixed by welding or bolting. The outer diameter of the spiral baffle 321 is slightly smaller than the inner diameter of the sieve cylinder 200, maintaining a gap of 5-10 mm between them. This allows the spiral baffle 321 to rotate smoothly and effectively guides the pulp to the discharge port 220. The support rod 400 is located within the intervals of the spiral baffle 321 and does not affect the spiral guiding function of the spiral baffle 321. The starting position of the spiral line of the spiral baffle 321 is close to the ending position of the bolt conveying section, and the ending position of the spiral baffle 321 is close to the discharge port 220, ensuring that the pulp can be smoothly guided from the striking section 320 to the discharge port 220.
[0049] As the rotating roller 300 rotates, the spiral baffle 321, with its spiral shape, propels the pulp within the beating section 320 along the axial direction of the sieve cylinder 200 towards the discharge port 220. During this movement, the spiral baffle 321 works in conjunction with the beating rod 410 on the rotating roller 300. On one hand, the spiral baffle 321 continuously delivers new pulp to the effective range of the beating rod 410, ensuring that the beating rod 410 continuously beats and removes the seeds from the pulp. On the other hand, after being beaten and removed from the seeds, the pulp, propelled by the spiral baffle 321, moves rapidly towards the discharge port 220 and is promptly discharged from the sieve cylinder 200, preventing excessive retention of the pulp within the sieve cylinder 200, which would affect the seed removal efficiency and the stability of the equipment operation. Simultaneously, the presence of the spiral baffle 321 ensures a more uniform distribution of the pulp within the sieve cylinder 200, which is beneficial for improving the overall seed removal effect.
[0050] In some examples, the scraper 420 is mounted on top of the support rod 400 and is made of wear-resistant rubber or high-strength plastic. These materials have good wear resistance and can avoid scratching the inner wall of the screen cylinder 200. The scraper 420 is elongated, and the scrapers 420 on adjacent support rods 400 are staggered and have overlapping parts to ensure thorough cleaning of the inner wall of the screen cylinder 200.
[0051] During the operation of the seed thresher, juice and fragments from the winter melon pulp may adhere to the inner wall of the sieve cylinder 200. The scraper 420 rotates together with the rotating roller 300 and support rod 400, and its close contact with the inner wall of the sieve cylinder 200 effectively scrapes away these adhering substances, preventing their accumulation. This not only helps maintain the unobstructed flow of the sieve holes in the sieve cylinder 200, allowing melon seeds and small-volume pulp to pass smoothly, but also prevents the adhering substances from affecting the beating effect of the striking rod 410 on the pulp and the guiding effect of the spiral baffle 321 on the pulp, ensuring that the seed thresher always operates at high efficiency.
[0052] Because the scraper 420 is long and narrow, it is difficult for the pulp to accumulate on the scraper 420. When the pulp on the scraper 420 accumulates to a certain extent, it will be thrown out or fall off under the action of centrifugal force and gravity.
[0053] In some examples, the sieve 500 is semi-circular, with its radius determined by the size of the sieve cylinder 200 and the equipment layout. It is generally slightly larger than or equal to the radius of the sieve cylinder 200 to ensure that it can completely catch the melon seeds and pulp falling from the sieve cylinder 200. The sieve mesh size of the sieve 500 is smaller than that of the melon seeds, ensuring that the seeds remain on the sieve 500, while smaller pieces of pulp and juice fall through the mesh. The sieve 500 is fixed to the frame 100 by welding or bolting, located directly below the sieve cylinder 200.
[0054] Screen 500 is mainly used for secondary screening of melon seeds and pulp falling from screen cylinder 200. After the initial seed removal is completed in screen cylinder 200, screen 500 catches the falling mixture and filters it through its sieve holes, leaving the melon seeds on screen 500 to further separate out small-volume melon pulp fragments, thus improving the purity of the melon seeds. The semi-circular shape of screen 500 allows the melon seeds to naturally gather at the bottom of screen 500 under the action of gravity, facilitating subsequent conveying by screw conveyor 600.
[0055] The screw conveyor 600 is rotatably mounted on the frame 100 via bearings at both ends, ensuring smooth rotation. A drive motor is connected to the shaft of the screw conveyor 600 via a belt or chain transmission mechanism, providing rotational power. The screw conveyor 600 abuts against the inner wall of the screen 500, effectively pushing the melon seeds on the screen 500 along its inner wall towards the seed outlet 120 during rotation. The spiral blades push the melon seeds on the screen 500 along its inner wall towards the seed outlet 120, achieving automatic seed collection and improving the efficiency and automation of seed collection.
[0056] In some examples, guide baffles 700 are also included, two of which are set on the frame 100. The guide baffles 700 are located on both sides of the screen cylinder 200 in the transverse direction. The guide baffles 700 are used to guide the material falling through the screen holes of the screen cylinder 200 to the screen mesh 500.
[0057] The guide baffle 700 is arc-shaped or rectangular, with a certain gap between it and both sides of the sieve cylinder 200. The length of the guide baffle is the same as the length of the sieve cylinder 200. The two guide baffles are arranged with the upper part farther apart and the lower part closer together. The guide baffles can block the melon seeds thrown out of the sieve cylinder 200, avoiding waste. Moreover, the guide baffles can ensure that the melon seeds coming out of the sieve cylinder 200 enter the screen 500, improving the efficiency and accuracy of material collection and ensuring the smooth progress of the seed removal process.
[0058] In some examples, the first rotating rod 810 is securely mounted on the frame 100 via a bearing housing, and one end is connected to a drive component (such as a motor) via a coupling or pulley drive to ensure effective power transmission. Along the axial direction of the first rotating rod 810, a plurality of first shearing blocks 811 are evenly spaced. The first shearing blocks 811 are fixed to the first rotating rod 810 by welding or bolting. The first shearing blocks 811 are elliptical in shape.
[0059] The second rotating rod 820 is arranged parallel to the first rotating rod 810 and is connected to the first rotating rod 810 via a gear transmission mechanism, ensuring that the two can rotate synchronously and relative to each other. Along the axial direction of the second rotating rod 820, several second shearing blocks 821 are also evenly distributed at intervals. The material of the second shearing blocks 821 is the same as that of the first shearing blocks 811, and their shape is also similar to an ellipse, with dimensions matching those of the first shearing blocks 811 to achieve the best shearing effect. Along the axial direction of the second rotating rod 820, the first shearing blocks 811 and the second shearing blocks 821 are distributed alternately at intervals, and along the radial direction of the second rotating rod 820, the first shearing blocks 811 and the second shearing blocks 821 have overlapping portions, the width of which is generally between 1-3 cm. The second shearing blocks 821 on the second rotating rod 820 are also fixed to the rod by welding or bolting, and their intervals are consistent with the intervals of the first shearing blocks 811 on the first rotating rod 810. The interval between adjacent first shearing blocks 811 and second shearing blocks 821 is smaller than the diameter of the sieve holes on the screen 500. The size of the first shearing blocks 811 and second shearing blocks 821 is adapted to the size of the discharge port 220 to ensure that the melon pulp falling out can be completely sheared by the first shearing blocks 811 and second shearing blocks 821 before falling onto the screen 500.
[0060] When the melon pulp falling from the discharge port 220 enters the area between the first rotating rod 810 and the second rotating rod 820, the driving component drives the first rotating rod 810 to rotate, and the first rotating rod 810 drives the second rotating rod 820 to rotate synchronously in the opposite direction through the transmission mechanism. During the rotation, the first shearing block 811 and the second shearing block 821 are staggered and their overlapping parts cooperate with each other, shearing the melon pulp like scissors. Because the melon pulp is continuously subjected to shearing force during its fall, it is sheared into a volume smaller than that of melon seeds, thus falling onto the screen 500 below. In this way, the screen 500 can screen melon seeds more efficiently and accurately, avoiding interference from larger melon pulp particles.
[0061] In some examples, several water spray elements 900 are mounted on the top of the frame 100. The water spray elements 900 are installed on the frame 100 via threaded connections or snap-fit fasteners. Each water spray element 900 has a water inlet at its top, connected to an external water pump via a flexible hose to ensure a stable water supply. The bottom of each water spray element 900 has multiple spray holes, arranged in a circular or elliptical shape.
[0062] The water spray unit 900 sprays water onto the pulp inside the sieve cylinder 200, softening it. During the seed removal process, the softened pulp, under the cutting and striking action of the striking rod 410, makes it easier for the seeds to detach from the pulp, improving seed removal efficiency. Furthermore, the sprayed water passes sequentially through the shearing device 800 and the sieve 500, washing away any remaining pulp on the shearing device 800 and allowing it to fall smoothly onto the sieve 500. This also helps the sieve 500 separate pulp and seeds, preventing pulp fragments from clogging the sieve's openings.
[0063] In some examples, the conveying direction of the screw conveyor 600 is opposite to that of the screw conveyor section 310. In practical applications, the seeds that first fall from the sieve cylinder 200 are usually distinct particles located on the periphery of the pulp; these seeds require minimal processing before being output. Subsequent seeds, after being knocked away, will have pulp adhering to them, and pulp fragments also need to travel a certain distance on the sieve 500 before falling through its openings. Throughout this process, water from the water spray unit 900 continuously drips, effectively cleaning the seeds.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
