Description
Technical Field
[0001] This application relates to the technical field of seed pretreatment, and in particular to a crushing device for corn seeds. Background Technology
[0002] Currently, traditional cellulose enzymatic hydrolysis processes typically involve multiple steps, including microbial culture, raw material pretreatment, fermentation, concentration and drying. Each step requires precise control of various parameters, such as temperature, pH value and fermentation time, to ensure maximum enzymatic hydrolysis efficiency.
[0003] The pretreatment steps include washing, drying, crushing, and screening. When crushing, the corn seeds are small and have smooth surfaces. Traditional crushing devices are relatively simple, including a crushing vessel, crushing blades, and a drive mechanism. In use, the corn seeds are placed in the crushing vessel, and then the drive mechanism drives the crushing blades to rotate. The rotating crushing blades stir the corn seeds. However, during the stirring process, the corn seeds fall due to their own gravity and tend to settle at the bottom of the crushing vessel, making it impossible for the crushing blades to complete all the stirring, resulting in poor crushing effect. Utility Model Content
[0004] To improve the crushing effect, this application provides a crushing device for corn seeds.
[0005] This application provides a corn seed crushing device, which adopts the following technical solution:
[0006] A corn seed crushing device, comprising:
[0007] The crushing vessel has a horizontal cylindrical cavity inside and a feeding hole for feeding materials.
[0008] The crushing rod rotates on the crushing vessel and is coaxial with the cylindrical cavity;
[0009] Multiple crushing blades are provided, and all of them are provided on the crushing rod;
[0010] The rotating rod rotates on the crushing vessel and along the inner wall of the cylindrical cavity;
[0011] A flipper, mounted on the rotating rod, is used to lift the corn seeds at the bottom.
[0012] A power mechanism is mounted on the crushing vessel and connected to the crushing rod and the tilting blade, used to drive the crushing rod and the tilting blade to rotate;
[0013] A discharge pipe is installed on the bottom wall of the crusher, communicates with the cylindrical cavity, and is equipped with a valve.
[0014] By adopting the above technical solution, firstly, the corn seeds to be crushed are added into the cylindrical cavity through the feeding hole on the crushing vessel. This feeding hole is designed for easy operation, ensuring a smooth and safe feeding process. Once the corn seeds are added, the power mechanism is activated. The power mechanism is connected to the crushing rod and the rotating rod, so it will simultaneously drive these two rods to start rotating. As the crushing rod rotates, the multiple crushing blades on it begin to crush the corn seeds in the cylindrical cavity. The design of these crushing blades can effectively apply pressure to the seeds, thereby achieving the crushing effect.
[0015] At the same time, the rotating rod also begins to rotate, and the flipping blades set on it begin to work. The function of the flipping blades is to push the corn seeds at the bottom of the cylindrical cavity upward, ensuring that all seeds can receive the action of the crushing blades evenly, avoiding the situation of piling up and not being crushed.
[0016] When the corn seeds are crushed to the required degree, turn off the power mechanism and open the valve on the discharge pipe; the crushed corn seeds will be smoothly discharged from the crushing kettle through the discharge pipe.
[0017] Through the design of the crushing rod and crushing blades, this device can efficiently crush corn seeds to meet production needs. The rotating blades ensure that the corn seeds in the cylindrical cavity are evenly crushed, avoiding local accumulation and uncrushed seeds. The design of the feeding hole and discharge pipe makes the operation simple and quick, improving work efficiency. The entire device has a compact structure, small footprint, and is easy to install and use. The connection between the power mechanism and the crushing rod and rotating rod is stable and reliable, ensuring the safety of the device during operation. At the same time, the design of the feeding hole and discharge pipe also takes into account the safety of the operators.
[0018] Optionally, the flipping blade and the crushing rod rotate in opposite directions.
[0019] By adopting the above technical solution, the rotation of the flipping blade in the opposite direction to the crushing rod enhances the mixing and tumbling of seeds within the cylindrical cavity, ensuring that each seed receives the crushing action evenly, greatly improving the uniformity of crushing. The movement of the flipping blade not only promotes the upward lifting and mixing of seeds but also helps to send larger or insufficiently crushed seeds back into the action area of the crushing blade, thereby improving the overall crushing efficiency. Although the movement of the flipping blade is increased, its enhanced mixing and crushing uniformity may reduce the total time and power input required to achieve the same crushing effect, thus reducing energy consumption to some extent. The rotation of the flipping blade in the opposite direction to the crushing rod requires a more refined and efficient design of the power mechanism and transmission system.
[0020] Optionally, the cutting portions of the flipping leaf and the breaking leaf are arranged alternately.
[0021] By adopting the above technical solution, the two are set up alternately, which facilitates the mixed shearing and crushing of corn seeds, thereby improving the crushing effect.
[0022] Optionally, the rotating rod slides and rotates on the crushing vessel, and the crushing vessel is provided with a sliding mechanism, which is connected to the rotating rod and drives the rotating rod to slide.
[0023] By adopting the above technical solution, before the crushing operation begins, the rotating rod is positioned at an initial position within the crushing vessel via a sliding mechanism. This position is typically determined based on the crushing requirements and the initial filling state of the seeds. Once the power mechanism is activated, the rotating rod begins to rotate, and simultaneously, the sliding mechanism starts working, driving the rotating rod to slide within the crushing vessel. As the rotating rod rotates, its rotating blades apply crushing and agitation to the corn seeds. At the same time, due to the sliding of the rotating rod, the effective range of the rotating blades continuously expands and changes within the cylindrical cavity, which helps to mix the seeds more evenly, ensuring that each seed receives crushing action. The sliding motion also promotes relative movement between seeds, further enhancing the crushing effect. During the crushing process, the sliding mechanism can dynamically adjust the position of the rotating rod as needed. For example, when insufficient seed crushing is detected in a certain area, the sliding mechanism can drive the rotating rod to move towards that area to strengthen the crushing action in that area. This dynamic adjustment capability improves the flexibility and adaptability of the crushing operation.
[0024] Optionally, the sliding mechanism includes:
[0025] A cam is mounted on the crushing vessel and located on one side of the rotating rod, and on the rotation path of the rotating rod;
[0026] A drive plate is mounted on the rotating rod and, as the rotating rod rotates, can abut against the cam and undergo relative displacement with the crushing vessel;
[0027] A reset component is disposed on the crushing vessel and connected to the drive plate, used to drive the drive plate closer to the crushing vessel.
[0028] By adopting the above technical solution, when the power mechanism is started and the rotating rod begins to rotate, the drive plate also rotates. As the rotating rod continues to rotate, the drive plate gradually approaches the cam. When the drive plate comes into contact with the cam, due to the continuous rotation of the rotating rod, the drive plate is obstructed by the cam, and the surface of the cam slides away from the crushing vessel.
[0029] As the rotating rod rotates further, the drive plate eventually disengages from the cam; at this point, the reset mechanism kicks in, resetting the drive plate (and the rotating rod) back to their original position. This process repeats when the rotating rod rotates back to the vicinity of the cam, forming a cycle.
[0030] The automatic sliding of the rotating rod on the crushing vessel is achieved through the contact between the cam and the drive plate, as well as the action of the reset component. This design simplifies the structure of the sliding mechanism, reduces manufacturing costs, and improves the reliability of the equipment. The sliding of the rotating rod allows the tilting blades to operate over a wider range within the crushing vessel, enabling more effective crushing and mixing of corn seeds. Simultaneously, the combined action of sliding and rotation helps break up the adhesion between seeds, further improving the crushing effect.
[0031] Optionally, the reset element includes:
[0032] A reset spring is disposed on the crushing vessel and connected to the drive plate, used to drive the drive plate closer to the crushing vessel.
[0033] By adopting the above technical solution, when the drive plate abuts against the cam, due to the continued rotation of the rotating rod, the drive plate is abutted by the cam, causing relative slippage. This causes the drive plate to move away from the crushing vessel, thereby driving the rotating rod to slip. At this time, due to the action of the return spring, the drive plate will try to maintain its original position (i.e., the position close to the crushing vessel). The abutment of the cam forces the drive plate to be unable to return to its original position. This slippage is achieved through the slippage of the guide rod on the crushing vessel and the elastic deformation of the return spring.
[0034] Optionally, the rotating rod is further provided with a mixing blade, which is located on the opposite side of the flipping blade.
[0035] By adopting the above technical solution, the mixing blades allow the rotating rod to not only crush and stir the corn seeds through the flipping blades during rotation, but also further mix the seeds through the mixing blades. This dual action helps to distribute the seeds more evenly, ensuring that each seed receives sufficient crushing and mixing treatment. The synergistic effect of the mixing blades and the flipping blades allows the seeds in the crushing vessel to be subjected to crushing force while also being stirred and mixed from different directions. This combined action helps to break up the adhesion and accumulation between seeds more quickly, improving crushing efficiency.
[0036] Optionally, a scraper is provided on the side of the mixing blade away from the axis of the rotating rod, and the scraper abuts against the inner wall of the cylindrical cavity and slides relative to it.
[0037] By adopting the above technical solution, the presence of the scraper allows the mixing blades to not only stir and mix the seeds during rotation, but also scrape off the seeds or materials adhering to the inner wall of the cylindrical cavity and remix them into the main flow through the relative sliding between the scraper and the inner wall of the cylindrical cavity. This helps to eliminate mixing dead zones and improve mixing uniformity. The contact and sliding between the scraper and the inner wall of the cylindrical cavity also plays an auxiliary crushing role. In particular, for larger particles or adhering materials on the inner wall, the scraper can scrape them off and crush them, thereby improving the overall crushing efficiency. During long-term crushing and mixing, materials may gradually accumulate on the inner wall of the cylindrical cavity. The scraper design can effectively prevent this accumulation, ensuring that the material is always kept in the main flow of crushing and mixing, avoiding equipment performance degradation or failure due to material accumulation.
[0038] In summary, this application includes at least one of the following beneficial technical effects:
[0039] 1. Through the design of the crushing rod and crushing blades, this device can efficiently crush corn seeds to meet production needs. The setting of the rotating blades ensures that the corn seeds in the cylindrical cavity can be uniformly crushed, avoiding local accumulation and uncrushed conditions. The design of the feeding hole and discharge pipe makes the operation simple and quick, improving work efficiency. The entire device has a compact structure, small footprint, and is easy to install and use. The connection between the power mechanism and the crushing rod and rotating rod is stable and reliable, ensuring the safety of the device during operation. At the same time, the design of the feeding hole and discharge pipe also takes into account the safety of operators.
[0040] 2. The presence of the scraper allows the mixing blades to not only stir and mix the seeds during rotation, but also scrape off seeds or materials adhering to the inner wall of the cylindrical cavity and remix them into the main flow through relative sliding between the scraper and the inner wall. This helps eliminate mixing dead zones and improves mixing uniformity. The contact and sliding between the scraper and the inner wall of the cylindrical cavity also plays an auxiliary role in crushing. In particular, for larger particles or adhering materials on the inner wall, the scraper can scrape them off and crush them, thereby improving the overall crushing efficiency. During long-term crushing and mixing, materials may gradually accumulate on the inner wall of the cylindrical cavity. The scraper design effectively prevents this accumulation, ensuring that the material is always kept in the main flow of crushing and mixing, avoiding equipment performance degradation or malfunctions caused by material accumulation.

Detailed Implementation
[0046] The following combination Figures 1 to 4 This application will be described in further detail.
[0047] This embodiment discloses a corn seed crushing device.
[0048] Reference Figure 1 and Figure 2 The corn seed crushing device includes: a crushing vessel 100, a crushing rod 210 rotatably mounted on the crushing vessel 100, a crushing blade 220 mounted on the crushing rod 210, a rotating rod 230 rotatably mounted on the crushing vessel 100, a tilting blade 240 mounted on the rotating rod 230, a power mechanism 300 mounted on the crushing vessel 100 for driving the crushing rod 210 and the rotating rod 230 to rotate, and a discharge pipe 400 mounted on the crushing vessel 100 for discharging the crushed corn seeds. When crushing corn seeds, the seeds are first placed into the crushing vessel 100, and then the power mechanism 300 drives the crushing rod 210 and the rotating rod 230 to rotate. The crushing rod 210 drives the crushing blade 220 to rotate, and the rotating rod 230 drives the tilting blade 240 to rotate. The crushing blade 220 and the tilting blade 240 agitate and crush the corn seeds. After crushing, the seeds are discharged through the discharge pipe 400.
[0049] The crushing vessel 100 is a horizontally placed cylindrical shape with an integral support leg placed on the ground. A horizontal cylindrical cavity 110 is formed inside the crushing vessel 100, and a feeding hole 120 is provided on the side of the crushing vessel 100 away from the ground. The feeding hole 120 is connected to the cylindrical cavity 110. The crushing rod 210 is rotatably connected to one end of the crushing vessel 100 and is concentric with the cylindrical cavity 110. Multiple crushing blades 220 are provided and evenly distributed on the crushing rod 210. The discharge pipe 400 is fixedly connected to the side of the crushing vessel 100 near the ground and is connected to the cylindrical cavity 110. A valve for discharging corn seeds is provided.
[0050] Reference Figure 2 , Figure 3 and Figure 4 The rotating rod 230 is L-shaped, with its long end parallel to the crushing rod 210. The rotating rod 230 and the crushing rod 210 rotate in opposite directions. Multiple tilting blades 240 are evenly distributed along the length of the rotating rod 230. The cutting parts of the tilting blades 240 and the cutting parts of the crushing blades 220 are staggered and can approach each other to cut and crush corn seeds. A rotating ring 270 is fixedly connected to the end of the rotating rod 230. The rotating ring 270 rotates and slides on the crushing vessel 100 and is sleeved on the crushing rod 210. The rotating ring 270 can rotate relative to the crushing rod 210. The rotating ring 270 can slide along the length of the crushing rod 210. The power mechanism 300 includes a fixed... A drive motor 310 is fixedly connected to one end of the crushing vessel 100. The output shaft of the drive motor 310 is coaxial with and detachably connected to the crushing rod 210. A first gear 320 is also keyed to the output shaft of the drive motor 310. A second gear 330 is rotatably connected to the crushing vessel 100 and meshes with the first gear 320. A gear ring 340 is rotatably connected to the crushing vessel 100 and meshes with the second gear 330. A rotating frame 350 is rotatably connected to the crushing vessel 100 and is fixedly connected to the gear ring 340. The rotating frame 350 is slidably connected to the rotating ring 270, and the rotating ring 270 slides along the axis of the crushing rod 210 on the rotating frame 350.
[0051] To facilitate the sliding of the rotating ring 270, a sliding mechanism 500 is provided on the crushing vessel 100. The sliding mechanism 500 includes a drive plate 520 fixedly connected to the rotating ring 270. The drive plate 520 is located between the rotating frame 350 and the crushing vessel 100, with gaps between it and both. The drive plate 520 is elongated and parallel to the end sidewall of the crushing vessel 100. The drive plate 520 is slidably connected to the rotating frame 350 along the axial direction of the rotating frame 350. A cam 510 is fixedly connected to the upper part. The surface of the cam 510 is smooth and rounded to form an arc-shaped surface. The cam 510 can intermittently abut against the drive plate 520. When the drive plate 520 abuts against the cam 510, the drive plate 520 can slide along the arc-shaped surface. A reset member 530 is provided on the crushing vessel 100. The reset member 530 includes a reset spring. The reset spring is fixedly connected to the rotating frame 350, abuts against the drive plate 520, and pushes the drive plate 520 closer to the crushing vessel 100.
[0052] To enhance the disturbance of corn seeds, a mixing blade 250 is also fixedly connected to the rotating rod 230. The mixing blade 250 is located on the opposite side of the flipping blade 240. The mixing blade 250 includes multiple blades and is inclined. A scraper 260 is integrally formed on the side of the mixing blade 250 away from the axis of the crushing rod 210. The scraper 260 abuts against the inner wall of the cylindrical cavity 110 and slides relative to it.
[0053] The implementation principle of a corn seed crushing device according to an embodiment of this application is as follows: First, corn seeds are added into the cylindrical cavity 110 of the crushing vessel 100 through the feeding hole 120; check whether the crushing rod 210 and the rotating rod 230 are installed correctly to ensure that they can rotate freely; start the drive motor 310, its output shaft starts to rotate, and drives the second gear 330 to rotate through the first gear 320; since the second gear 330 meshes with the gear ring 340, the gear ring 340 also rotates accordingly.
[0054] The rotating frame 350 is fixedly connected to the gear ring 340, so the rotating frame 350 also rotates with the gear ring 340. However, since the rotating ring 270 and the rotating frame 350 are slidably connected, the rotating ring 270 rotates together with the rotating frame 350. The output shaft of the drive motor 310 is coaxially connected to the crushing rod 210, and the crushing rod 210 starts to rotate, driving the crushing blade 220 to perform preliminary crushing and agitation on the corn seeds. The rotating rod 230 rotates in the opposite direction to the crushing rod 210, driving the turning blade 240 to further crush and agitate the corn seeds. The cutting part of the turning blade 240 and the cutting part of the crushing blade 220 are staggered, so that the two can cooperate with each other to crush the seeds more efficiently.
[0055] Meanwhile, the sliding mechanism 500 begins to function. When the rotating ring 270 moves the drive plate 520 to the vicinity of the cam 510, the drive plate 520 intermittently abuts against the cam 510. Due to the obstruction of the cam 510, the drive plate 520 slides relative to the crusher 100 along the surface of the cam 510. After the cam 510 separates from the drive plate 520, the reset member 530 functions after the drive plate 520 and cam 510 disengage, driving the drive plate 520 (as well as the rotating ring 270 and the rotating rod 230) back to their original positions. Thus, as the rotating rod 230 continues to rotate, the above sliding and reset processes will be repeated continuously.
[0056] As the rotating rod 230 rotates, the mixing blade 250 also rotates. The mixing blade 250 is located on the opposite side of the tilting blade 240, and its multiple blades are tilted to help to more thoroughly stir and mix the seeds.
[0057] When the desired crushing degree is reached, the drive motor 310 is turned off. At this time, the crushing rod 210 and the rotating rod 230 stop rotating; the valve on the discharge pipe 400 is opened, and the crushed corn seeds are smoothly discharged from the crushing kettle 100 through the discharge pipe 400.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
