Technical Field
[0001] This utility model belongs to the field of starch raw material crushing technology, and in particular relates to a rapid crushing device for starch raw materials. Background Technology
[0002] Starch is frequently used in people's lives. It can be extracted from starchy substances such as corn, sweet potatoes, wild acorns, and kudzu root. The process involves crushing the raw materials to produce starch.
[0003] During the crushing process of starch raw materials, the damaged raw materials will stick to the inner wall of the crushing barrel, while the raw materials that are not fully crushed at the bottom of the device will be discharged together with the crushed raw materials, resulting in poor crushing effect of the device. In order to address the above problems, the following solutions are proposed. Utility Model Content
[0004] The purpose of this invention is to provide a rapid crushing device for starch raw materials. By setting a scraper, the raw materials adhering to the inner wall of the device can be scraped off, and large pieces of raw materials can be crushed again. This solves the problem that in existing devices, raw materials will stick to the inner wall of the crushing barrel and the raw materials at the bottom that have not been fully crushed will be discharged together with the crushed raw materials.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a rapid crushing device for starch raw materials, including a crushing mechanism. The crushing mechanism includes a shell, an inlet door on the left side of the shell, and an outlet at the bottom of the shell. It also includes:
[0007] The scraping mechanism includes a rotating rod disposed inside the housing, a sliding rod slidably connected to the inner wall of the rotating rod, and a spring fixedly connected to the bottom of the sliding rod;
[0008] The screening mechanism includes a screen that is slidably connected to the inner wall of the outer shell, a guide shell that is fixedly connected to the bottom of the screen, and four right-angle plates that are fixedly connected to the outer wall of the screen.
[0009] Furthermore, a support leg is fixedly connected to the bottom of the outer casing, a support plate is fixedly connected to the back of the outer casing, and a motor is fixedly connected to the top of the support plate. By setting the support plate, the motor can be fixed and supported.
[0010] Furthermore, the motor output end is fixedly connected to a rotating shaft via a coupling. The outer surface of the rotating shaft is rotatably connected to the inner wall of the housing. Several crushing rods are fixedly connected to the outer surface of the rotating shaft. By setting the crushing rods, the raw materials can be crushed.
[0011] Furthermore, the inner wall of the rotating rod is fixedly connected to the outer surface of the rotating shaft, the bottom of the spring is fixedly connected to the bottom of the inner wall of the rotating rod, and a scraper is fixedly connected to the top of the sliding rod. By setting the scraper, the broken residue adhering to the inner wall of the outer casing can be scraped off.
[0012] Furthermore, two limiting bent rods are fixedly connected to the inner wall of the outer shell. The top of the limiting bent rod has a through hole, which penetrates the bottom of the limiting bent rod. By setting the limiting bent rod, the scraper can be limited after the screen moves down.
[0013] Furthermore, the outer surface of the guide shell is slidably connected to the inner wall of the outer shell, and the inner wall of the outer shell is provided with four sliding grooves. The outer surface of the right-angle plate is slidably connected to the inner wall of the corresponding sliding groove. A limit rod is slidably connected to the inner wall of the right-angle plate. The top and bottom of the limit rod are slidably connected to the inner wall of the outer shell. A spring is sleeved on the outer wall of the limit rod. By setting the limit rod, the right-angle plate can be limited.
[0014] Furthermore, the top of the second spring is fixedly connected to the inner wall of the outer shell, the bottom of the second spring is fixedly connected to the outer wall of the right-angle plate, a lifting plate is slidably connected to the outer surface of the limiting rod, an electric push-pull rod is provided on the top of the lifting plate, the bottom of the output end of the electric push-pull rod is fixedly connected to the top of the lifting plate, and the top of the electric push-pull rod is fixedly connected to the inner wall of the outer shell. By setting the electric push-pull rod, the screen can be intermittently moved up and down, so as to achieve the crushing effect without affecting the output efficiency.
[0015] This utility model has the following beneficial effects:
[0016] 1. In the crushing process of this utility model, the feed door is opened, and the starch raw material is fed into the interior of the outer shell. Then, the motor is started, driving the rotating shaft to rotate. The rotating shaft drives several crushing rods to rotate, thereby crushing the raw material. The crushed material falls through the screen into the guide shell and is discharged from the outlet along the guide shell. During the rotation of the rotating shaft, it also drives the rotating rods to rotate. The rotating rods, in turn, drive the sliding rods and scrapers to rotate together. As the rotation speed increases, the sliding rods and scrapers move away from the rotating shaft due to centrifugal force, stretching the spring until the outer surface of the scraper contacts the inner wall of the outer shell. At this point, as the rotation speed increases... The rotating shaft drives the scraper to rotate, which scrapes away the crushed residue adhering to the inner wall of the outer casing. At the same time, the scraper can also move the incompletely crushed material that falls on the top of the screen along with it during the rotation. When the scraper moves the incompletely crushed material to a certain angle, the material will fall again and be crushed again by the crushing rod. This design can scrape away the crushed residue adhering to the inner wall of the outer casing by the scraper, avoiding the accumulation of residue on the shell wall and keeping the inside of the equipment clean. At the same time, the screen can prevent the incompletely crushed material from falling and further crush the large pieces of material, thereby improving the degree of crushing and helping to obtain finer crushed products.
[0017] 2. After a period of operation, this utility model can activate the electric push-pull rod to move the lifting plate downwards. At this time, the compressed spring will push the right-angle plate downwards, and the right-angle plate will move downwards along with the screen. During this process, the scraper will be blocked by the limiting bent rod and will not contact the screen. However, the crushed material will still fall on the top of the screen, thus giving the crushed material enough time to fall off the screen and preventing the scraper from continuously moving the material, which would affect the discharge efficiency. After a period of operation, the electric push-pull rod is controlled again to reset the lifting plate, thereby resetting the screen. At this time, the scraper can scrape off the crushed material on the top of the screen, performing secondary crushing while preventing the screen from being blocked. After this, the above steps of moving the screen up and down are repeated, which can balance the crushing effect without affecting the discharge efficiency.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 As shown, this utility model is a rapid crushing device for starch raw materials, including a crushing mechanism 1. The crushing mechanism 1 includes a housing 101, an inlet gate 1011 on the left side of the housing 101, and an outlet 1012 at the bottom of the housing 101. It also includes:
[0031] The scraping mechanism 2 includes a rotating rod 201 disposed inside the housing 101, a sliding rod 202 slidably connected to the inner wall of the rotating rod 201, and a spring 203 fixedly connected to the bottom of the sliding rod 202.
[0032] The screening mechanism 3 includes a screen 301 that is slidably connected to the inner wall of the outer shell 101, a guide shell 302 that is fixedly connected to the bottom of the screen 301, and four right-angle plates 303 that are fixedly connected to the outer wall of the screen 301.
[0033] A support leg 102 is fixedly connected to the bottom of the outer casing 101, a support plate 103 is fixedly connected to the back of the outer casing 101, and a motor 104 is fixedly connected to the top of the support plate 103.
[0034] The output end of the motor 104 is fixedly connected to the rotating shaft 105 via a coupling. The outer surface of the rotating shaft 105 is rotatably connected to the inner wall of the outer casing 101. Several crushing rods 106 are fixedly connected to the outer surface of the rotating shaft 105. When crushing is performed, the feed door 1011 is opened and the starch raw material is put into the interior of the outer casing 101. Then the motor 104 is started to drive the rotating shaft 105 to rotate. The rotating shaft 105 will drive the several crushing rods 106 to rotate, thereby crushing the raw material.
[0035] The inner wall of the rotating rod 201 is fixedly connected to the outer surface of the rotating shaft 105. The bottom of the spring 203 is fixedly connected to the bottom of the inner wall of the rotating rod 201. The top of the sliding rod 202 is fixedly connected to the scraper 204. During the rotation of the rotating shaft 105, it will also drive the rotating rod 201 to rotate. During the rotation of the rotating rod 201, it will drive the sliding rod 202 and the scraper 204 to rotate together. As the rotation speed increases, the sliding rod 202 and the scraper 204 will move away from the rotating shaft 105 together due to the centrifugal force and stretch the spring 203 until the outer surface of the scraper 204 contacts the inner wall of the outer shell 101. At this time, as the rotating shaft 105 drives the scraper 204 to rotate, the scraper 204 will scrape off the broken residue attached to the inner wall of the outer shell 101.
[0036] Two limiting bent rods 205 are fixedly connected to the inner wall of the outer shell 101. The top of the limiting bent rod 205 is provided with a through hole 206, which penetrates the bottom of the limiting bent rod 205. When the screen 301 drives the guide shell 302 to reset, the broken material between the top of the guide shell 302 and the bottom of the limiting bent rod 205 can be discharged through the through hole 206, preventing too much material from getting stuck between the limiting bent rod 205 and the guide shell 302, which would prevent the guide shell 302 from being completely reset.
[0037] The outer surface of the guide shell 302 is slidably connected to the inner wall of the outer shell 101. The inner wall of the outer shell 101 is provided with four sliding grooves 304. The outer surface of the right-angle plate 303 is slidably connected to the inner wall of the corresponding sliding groove 304. The inner wall of the right-angle plate 303 is slidably connected to a limiting rod 305. The top and bottom of the limiting rod 305 are slidably connected to the inner wall of the outer shell 101. A spring 306 is sleeved on the outer wall of the limiting rod 305. The crushed raw material will fall into the guide shell 302 through the screen 301 and be discharged from the discharge port 1012 along the guide shell 302.
[0038] The top of spring 306 is fixedly connected to the inner wall of outer shell 101, and the bottom of spring 306 is fixedly connected to the outer wall of right-angle plate 303. A lifting plate 307 is slidably connected to the outer surface of the limiting rod 305. An electric push-pull rod 308 is installed on the top of the lifting plate 307. The bottom of the output end of the electric push-pull rod 308 is fixedly connected to the top of the lifting plate 307, and the top of the electric push-pull rod 308 is fixedly connected to the inner wall of outer shell 101. After a period of operation, the electric push-pull rod 308 can be activated to move the lifting plate 307 downwards. At this time, spring 306, under compression, will push the right-angle plate 303 downwards, causing the right-angle plate 303 to move downwards along with the screen 301. Meanwhile, the scraper 204 is rotating... The material will be blocked by the limiting bent rod 205 and will not come into contact with the screen 301. However, the crushed material will still fall on the top of the screen 301, thus giving the crushed material enough time to fall off the screen 301. This prevents the scraper 204 from continuously moving the material and affecting the discharge efficiency. After running for a period of time, the electric push-pull rod 308 is controlled again to drive the lifting plate 307 to reset, thereby resetting the screen 301. At this time, the scraper 204 can scrape off the crushed material on the top of the screen 301, performing secondary crushing while preventing the screen 301 from being blocked. After that, the above steps of moving the screen 301 up and down are repeated. This can balance the crushing effect without affecting the discharge efficiency.
[0039] One specific application of this embodiment is:
[0040] When using this device, first install it in the designated location. During crushing, open the feed door 1011 and feed the starch raw material into the outer shell 101. Then, start the motor 104 to drive the rotating shaft 105 to rotate. The rotating shaft 105 will drive several crushing rods 106 to rotate, thereby crushing the raw material. The crushed raw material will fall through the screen 301 into the guide shell 302 and be discharged from the discharge port 1012 along the guide shell 302. During the rotation of the rotating shaft 105, it will also drive the rotating rod 201 to rotate. During the rotation of the rotating rod 201, it will drive the sliding rod 202 and the scraper 204 to rotate together. As the rotation speed increases, the sliding rod 202 and the scraper 204 will move away from the rotating shaft 105 due to centrifugal force and stretch the spring 203 until... The outer surface of the scraper 204 contacts the inner wall of the outer shell 101. At this time, as the rotating shaft 105 rotates the scraper 204, the scraper 204 will scrape off the crushed residue attached to the inner wall of the outer shell 101. At the same time, the scraper 204 can also move the incompletely crushed material that has fallen on the top of the screen 301 along with it during the rotation. When the scraper 204 moves the incompletely crushed material to a certain angle, the material will fall again and be crushed again by the crushing rod 106. This design can scrape off the crushed residue attached to the inner wall of the outer shell by the scraper 204, avoid the residue from accumulating on the shell wall, keep the inside of the equipment clean, and at the same time, the screen 301 can prevent the incompletely crushed material from falling and then crush the large pieces of material again, thereby improving the degree of crushing and helping to obtain finer crushed products.
[0041] After a period of operation, the electric push-pull rod 308 can be activated to move the lifting plate 307 downward. At this time, the spring 306, which is under compression, will push the right-angle plate 303 downward. The right-angle plate 303 will move the screen 301 downward together. During this process, the scraper 204 will be blocked by the limiting bent rod 205 and will not come into contact with the screen 301. However, the crushed material will still fall on the top of the screen 301, thus giving the crushed material enough time to fall off the screen 301 and preventing the scraper 204 from continuously moving the material and affecting the discharge efficiency. After a period of operation, the electric push-pull rod 308 can be controlled again to reset the lifting plate 307, thereby resetting the screen 301. At this time, the scraper 204 can scrape off the crushed material on the top of the screen 301, performing secondary crushing while preventing the screen 301 from being blocked. After this, the above steps of moving the screen 301 up and down are repeated. This can balance the crushing effect without affecting the discharge efficiency.
