Description

Technical Field

[0001] This utility model relates to the field of corn peeling equipment, and in particular to a discharge auger mechanism with corn husk shredding function and a corn peeling machine. Background Technology

[0002] Corn peeling machines are indispensable equipment in modern agriculture and food processing, widely used in various fields such as agricultural planting, food processing, feed production, and biomass energy production, with a consistently stable market demand. With continuous advancements in agricultural technology, the performance of corn peeling machines has been significantly improved, with continuously optimized peeling rates and productivity, while breakage and loss rates have been further reduced, better meeting the needs of agricultural production.

[0003] Corn peeling machines are typically powered by electric motors or diesel engines, connected to the drive shaft via belts, chains, or gears, providing power for the entire peeling process. The frame serves as the supporting structure, securing and supporting other components to ensure the machine's stability and overall integrity. It is generally equipped with one or two pairs of longitudinally arranged rubber peeling rollers. The surface of the rubber rollers has a certain roughness to increase friction with the corn cobs, thus better removing the husks. The drive shaft has a spiral and rubber spikes. The spiral propels the corn cobs forward, while the rubber spikes remove the husks through friction and compression. In addition to friction, the peeling device also exerts a squeezing and tearing effect on the corn cobs. For example, with the combination of the spiral and rubber spikes, as the spiral propels the cob forward, the rubber spikes embed and tear the husks, while the rubber wheel on the drive shaft applies pressure to the cob, making the husks easier to peel off. After peeling, the corn husks and corn cobs are discharged through their respective outlets. The corn husks are collected and processed after being discharged from the corn husk outlet, while the peeled corn cobs are discharged from the corn cob outlet, completing the entire peeling process.

[0004] However, while corn peeling machines have improved corn processing efficiency to some extent in the current agricultural machinery market, they also present several troublesome hidden problems. In terms of construction, many corn peeling machines use rubber studs to assist in the peeling operation. These rubber studs are prone to falling off during long-term use. Once the rubber studs fall off, the internal screws are exposed. When corn is processed in the peeling machine, these exposed screws come into direct contact with the corn kernels. Because the screws are hard and have a rough surface, the corn kernels are inevitably scratched and bumped during the high-speed peeling process, leading to kernel damage. This has a very negative impact on the quality of the corn and its subsequent storage and processing. Secondly, the auger plays an important role in the corn peeling process, but it also faces a dilemma. If a softer auger design is used, the friction is insufficient when interacting with the corn husk and kernels, making it difficult to effectively peel the husk from the kernel, significantly reducing peeling efficiency and seriously affecting the overall processing progress. Conversely, while using a high-friction spiral strip can improve peeling efficiency, the excessive friction between the strip and the corn kernels can damage them during the peeling process, leading to a decrease in kernel integrity. This also reduces corn quality and wastes resources, making it difficult to find an ideal balance between efficiency and kernel integrity. The subsequent processing of corn husks also presents significant challenges. After the husks are removed and discharged, their unique properties prevent them from being directly used as feed for cattle and horses. Typically, secondary crushing and grinding are required. This undoubtedly increases the number of steps and time involved, raising production costs. Furthermore, using conventional crushers or grinders often results in the husks becoming powdered or finely shredded. Such feed lacks chewiness and is unpalatable to livestock, leading to feed waste. Some might think that simple kneading can solve the problem, but in reality, due to the distinctly fibrous structure of corn husks, simple kneading is insufficient to achieve the desired shape, often requiring secondary kneading. The secondary kneading not only makes the process more complicated and cumbersome, but also increases the breakage rate during operation, further exacerbating the waste of resources and making the effective utilization of corn husks extremely difficult. Summary of the Invention

[0005] To address the shortcomings and defects of the existing technology, the inventors, through research and development, improved the key components of the equipment, solving the aforementioned problems. This results in a more durable and stable operation, protecting the integrity of the corn kernels while improving peeling efficiency. Furthermore, the innovative auger roller structure, combined with the design of the kneading fixed and moving blades at the discharge end, enables the one-time kneading of the corn husks into shreds, shortening the processing time, improving efficiency, and ensuring the integrity of the corn kernels. Specifically, this utility model is implemented as follows:

[0006] A auger mechanism with corn husk shredding function includes an auger conveying section and a discharge end installed at the end of the auger conveying section. The auger conveying section includes: an auger roller arranged laterally; several screws perpendicular to the axial direction mounted on the roller surface and protruding upwards; a spiral winch spirally wound around the surface of the auger roller, extending from the beginning to the end of the roller; the outer edge of the spiral winch has several continuous sharp teeth forming a toothed edge; the discharge end includes: a discharge hood installed on the auger roller. The end of the roller has an inner opening on the side facing the auger roller, and the discharge port is set in a horizontal direction perpendicular to the axis of the auger roller. The discharge blades are set on the roller surface inside the discharge hood. Each blade of the discharge blades is equipped with several kneading knives on its top edge. Several fixed kneading knives that are adapted to the kneading knives are installed on the bottom plate of the discharge port of the discharge hood. This allows the kneading knives and the fixed kneading knives to work together to knead and shred the corn husks as the auger roller rotates, and then blow the corn husks out as the discharge blades rotate.

[0007] Furthermore, the front edge of the kneading moving blade is a beveled surface with toothed blades, and several are evenly and equidistantly distributed on the upper edge of the discharge blade, with the blade head extending beyond the upper edge of the discharge blade; several kneading fixed blades are fixedly installed on the fixed blade base plate, which is fixed to the base plate of the discharge port. The kneading fixed blades are arranged vertically and horizontally, and their installation displacement is offset from that of the kneading moving blades. Furthermore, the front and rear blade heads or the blade head facing backward of the kneading fixed blades are provided with beveled surfaces with toothed blades.

[0008] Furthermore, the kneading fixed blades are in two sets. One set is located at the bottom of the discharge hood near the discharge port, and the other set is located on the inner side wall of the discharge hood away from the discharge port. The blades of these two sets of kneading fixed blades are arranged opposite each other and are staggered. One set is used to face one side of the kneading moving blade, and the other set is used to face the other side of the kneading moving blade.

[0009] Furthermore, each set of kneading knives is arranged in two rows, and the gap between the kneading knives and the kneading stationary knives is maintained between 1.5 and 5 mm when the kneading knives pass by the kneading stationary knives; and the inclined surfaces of the toothed blades on the kneading knives and the corresponding kneading stationary knives are arranged facing each other.

[0010] Another aspect of this utility model provides a corn peeling machine with corn husk shredding function, including a flexible roller and a peeling spiral roller, and the discharge auger mechanism as described above is arranged below the flexible roller and the peeling spiral roller.

[0011] A peeling spiral roller has a rubber strip spirally wound on the roller body, and several rubber nails are installed on the surface of the roller body. The rubber nails are arranged in multiple groups between the rubber strips along the axis of the roller body.

[0012] A flexible roller is set on one side of the peeling spiral roller, forming an inwardly rotating roller assembly with the peeling spiral roller. The surface of the flexible roller can contact the rubber belt on the inner side to clamp the corn husk and pull it downward to remove the husk.

[0013] Furthermore, a perforated metal sheet is embedded inside the rubber nail, and a side pad is installed below it. The side pad is integrally formed and includes a base plate and two side baffles. The side baffles are set on two sides away from the flexible roller shaft. The rubber nail is installed on the base plate and is adapted to the two side baffles. It is fixed to the shaft of the peeling spiral roller shaft by screws passing through the holes in the perforated metal sheet. The height of the tail surface of the screw is lower than the height of the rubber nail block surface.

[0014] Furthermore, several metal teeth are installed on the feeding section of the peeling spiral roller shaft. The top edge of the metal teeth is a rack structure, and they are arranged on the roller surface of the peeling spiral roller shaft along the axial direction. No rubber nails are installed in this feeding section.

[0015] Furthermore, the rubber strips are arranged in pairs, with their surfaces at the same height.

[0016] Furthermore, the metal serrations are arranged vertically along the axial direction of the peeling spiral roller shaft, and several arc-shaped protrusions with alternating concave and convex distribution are provided on the top edge.

[0017] The working principle of this utility model is as follows: The auger roller of the discharge auger mechanism with corn husk shredding function is arranged horizontally, and the screws are installed perpendicular to the axial direction on the protrusions on its roller surface. The spiral winch is spirally wound around the surface of the auger roller from the beginning to the end, and its outer edge has continuous sharp teeth. During operation, the material falls into the auger conveying section from above. As the auger roller rotates, the screws can initially process the material. The screws can pry and wrap around the corn husks. Subsequently, the toothed edge of the spiral winch can contact the other part of the corn husks. Due to its spiral arrangement, the toothed structure on it has a pulling and tearing effect on the corn husks. Under the action difference, the corn husks are initially pulled and refined from large leaf shapes, and also participate in the material transmission action, quickly pushing the initially refined corn husks towards the discharge end. When the material reaches the discharge end, the inner opening of the discharge hood at the end of the auger receives the corn husks. The discharge blades rotate with the auger, and the kneading moving blades on the top edge cooperate with the kneading fixed blades on the bottom plate of the discharge port of the discharge hood. The toothed blades of the kneading moving blades are evenly distributed on the upper edge of the blades and the blades protrude. The kneading fixed blades are arranged horizontally and vertically and are staggered with the kneading moving blades. The front and rear blades or the rear blades have toothed blades. The two sets of kneading fixed blades are located at the bottom of the discharge hood, near and far from the discharge port, and are relatively staggered. The gap between the two rows of kneading moving blades and kneading fixed blades is between 1.5-5mm and the toothed blades face each other. The relative movement of the moving blades and fixed blades kneads the corn husks and finally blows the corn husks out from the discharge port of the discharge hood. At the intersection of the fixed and moving blades, the corn husks are subjected to a kneading and pulling action, further refining the initially finely shredded corn husks. The key lies in controlling the gap between the kneading moving blade and the kneading fixed blade. This ensures that the part of the corn husk in contact with the fixed blade is in a fixed position, while the moving blade creates a pulling and tearing position. This kneading and tearing action further pulls the corn husks into shreds, thus completing the secondary shredding process in a short time and discharging the material. The structural design of the beveled toothed blade at the front of the kneading moving blade, the protruding blade head, and the staggered arrangement of the kneading fixed blade, as well as the beveled toothed blades at the front and rear or rear ends of the blade head, complements the pre-treatment function of the screws and spiral winch in the auger conveyor section. The pre-treatment in the auger conveyor section initially breaks down and refines the corn husks as a whole, while the structure of the fixed and moving blades further kneads and tears the initially refined corn husks, pulling them into shreds. The combination of these two functions allows corn husks to undergo a secondary shredding and kneading process and be discharged simultaneously during the conveying and discharging process in a short time.

[0018] The working principle of a corn peeling machine with corn husk shredding function: This corn peeling machine includes a flexible roller shaft and a peeling spiral roller shaft, with the aforementioned discharge auger mechanism arranged below it. A rubber belt is spirally wound around the peeling spiral roller shaft and several rubber nails are installed. Each rubber nail contains a perforated metal plate and has a side-mounted gasket below it. It is fixed to the shaft body with screws, the tail of which is lower than the surface of the rubber nail. The feeding section has metal teeth and no rubber nails in this section. The two rubber belts are parallel and at the same height. The rubber nail has a perforated metal plate inside, through which the screw passes. When force is applied during use, the force is mainly concentrated on the perforated metal plate, thus reducing stress concentration and the probability of breakage or tearing, thereby extending the service life of the rubber nail. Furthermore, an L-shaped side pad is placed on the opposite side of the force-bearing surface to provide limiting and blocking force for the rubber nail during operation, thereby reducing the probability of tearing or breakage caused by lateral displacement and further improving the service life of the rubber nail. Metal serrations are arranged at the feeding section; the arc-shaped protrusions on the serrations can move the corn cob and lift the corn husks during rotation. This design loosens and lifts the corn husks from their adhered state to the kernels, making them easier for the flexible roller surface and the inner side of the rubber belt to grip and pull downwards, thus peeling the corn. This improves the efficiency of corn peeling. Using the rubber belt as a clamping element not only increases the friction on the corn husks, improving peeling efficiency, but also effectively protects the peeled corn kernels from damage. Therefore, it yields corn cobs with good integrity and a high peeling rate. The arc-shaped protrusion design improves the efficiency of peeling the corn husks without scratching the kernels, which is the core guarantee for improving efficiency and quality. After peeling, the material falls into the discharge auger mechanism below. The discharge auger mechanism shreds the corn husks according to the above principle, thus realizing the integrated operation of corn peeling and corn husk shredding.

[0019] The beneficial technical effects of this utility model compared with the prior art are:

[0020] (1) The discharge auger mechanism has the functions of efficient material transmission and preliminary processing. The interaction between the screw and the spiral winch can achieve the function of preliminary tearing and refining of corn husks while rapidly conveying them. The kneading moving blade on the discharge fan and the kneading fixed blade on the bottom plate of the discharge hood cooperate with each other. Through the relative movement of the moving blade and the fixed blade, the corn husks are kneaded and torn more finely a second time, and further pulled into a fine filament structure. This combination achieves the secondary continuous and rapid refining of corn husks, combining the conveying section and the fine crushing and kneading section into one station to achieve two functions at the same time, which greatly improves the processing efficiency of corn husks and significantly shortens the processing flow and procedures.

[0021] (2) The gap between the kneading moving blade and the kneading stationary blade is controlled between 1.5-5mm to ensure that the corn husks are kneaded and pulled at the intersection of the stationary and moving blades, thereby achieving efficient secondary filamentization. The beveled surface of the toothed blade and the protruding blade head at the front of the kneading moving blade, as well as the staggered arrangement of the kneading stationary blade and the beveled surface of the toothed blades at the front and rear, improve the cutting efficiency and durability of the blades. This blade assembly structure design allows the processed corn husks to achieve a narrower filamentous structure, and because they form a fibrous structure after being pulled, it increases the comfort and palatability of the feed for cattle and horses. It can be fed directly to livestock without secondary processing and without causing additional waste, and it also solves the problem of livestock finding it difficult to eat or disliking to eat.

[0022] (3) The metal augers in the feeding section have arc-shaped protrusions, which can move the corn cob and lift the corn husks during rotation, so that the corn husks change from an attached state to a loose and raised state, which is convenient for subsequent clamping and pulling. The flexible roller shaft and the peeling spiral roller shaft form an inward rotating roller assembly. Through the clamping action of the rubber belt and rubber nails, the corn husks are effectively clamped and pulled, which improves the peeling efficiency. At the same time, it can also effectively improve the corn peeling rate, reduce the occurrence of incomplete peeling, and improve the peeling efficiency.

[0023] (4) Using rubber bands as clamping components not only increases the friction on the corn husks and improves peeling efficiency, but also effectively protects the peeled corn kernels from damage, resulting in corn cobs with good integrity and a high peeling rate. A perforated metal plate is embedded inside the rubber nail, through which the screw passes and is fixed to the shaft. When under stress, the force is mainly concentrated on the perforated metal plate, reducing stress concentration on the rubber nail and decreasing the probability of breakage and tearing. This reduces the likelihood of exposed screws damaging the corn kernels, extending the equipment's service life while improving the integrity and goodness rate of the processed corn, ensuring the quality of the corn cobs.

[0024] In summary, this auger mechanism with corn husk shredding function and the corn peeling machine with this auger mechanism, through optimized design and structure, achieve efficient material transfer, preliminary processing, fine shredding, secondary crushing, and efficient corn peeling and kernel protection, while extending the service life of key components and improving the overall performance of the equipment.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0039] Example 1: Working process of the auger conveyor section

[0040] Material input: The material (corn husks) is fed in from above the auger conveyor section. 2.

[0041] Preliminary processing: The auger roller 1 begins to rotate. Several screws 11 are installed perpendicular to the axial direction on the roller surface of the auger roller 1. As the auger roller 1 rotates, the screws 11 can move and wrap around the corn husks. The outer edge of the spiral winch 12 has several continuous sharp teeth 13, forming a toothed edge. These toothed edges pull and tear the corn husks during rotation. The screws 11 and the spiral winch 12 form a fixed-motion cooperation, thus efficiently refining the corn husks from large leaf-shaped pieces. A corn leaf that is originally 3-7 cm wide will be processed into a thin leaf that is 2-4 cm wide. The cooperation between the screws 11 and the spiral winch 12 participates in the conveying of the corn husks, quickly pushing the preliminarily refined corn husks towards the discharge end.

[0042] The discharge end workflow is as follows: The discharge hood 14 is installed at the end of the auger roller 1, with an inner opening 15 on the side facing the auger roller 1. Corn husks are conveyed by the auger roller 1 to the inner opening 15 of the discharge hood 14 and enter the discharge hood 14. The discharge blades 17 are set on the roller surface inside the discharge hood 14. Several kneading blades 18 are set on the top edge of each blade. The front edge of the kneading blades 18 is a beveled surface with toothed blades 10, which are evenly and equidistantly distributed on the upper edge of the discharge blades 17, and the blade heads extend beyond the upper edge of the discharge blades 17. In conjunction with this, several fixed kneading blades 19 are fixedly installed on the fixed blade base plate 190, which is fixed to the base plate of the discharge port 16. The fixed kneading blade 19 is arranged vertically and horizontally, and its installation displacement is offset from that of the moving kneading blade 18. Both the front and rear blades of the fixed kneading blade 19, or the rearmost blade, are equipped with beveled toothed blades 10. As the auger roller 1 rotates, the discharge fan 17 also rotates. The moving and fixed kneading blades 18 work together to knead and shred the corn husks through the relative movement of the moving and fixed blades. The gap between the moving and fixed kneading blades 18 and 19 is maintained between 1.5 and 5 mm, causing the corn husks to be squeezed and pulled at the intersection of the fixed and moving blades, thus further refining the initially finely shredded corn husks. The key is controlling the gap between the moving and fixed kneading blades 18 and 19, ensuring that the part of the corn husks in contact with the fixed blades forms a fixed position, while the moving blades form a pulling and tearing position. This kneading and tearing action further stretches the corn husks into shreds. That is, the corn husks, which are 2-4 cm wide, are rubbed and formed into thin shreds 1-2 cm wide. The discharge port 16 is set in a horizontal direction perpendicular to the axis of the auger roller 1. The rubbed and shredded corn husks are blown out by the discharge blades 17 through the discharge port 16 of the discharge hood 14. The entire processing is completed.

[0043] Example 2: Working process and steps of a corn peeling machine

[0044] Corn cob entry: Place the corn cobs to be processed into the feed inlet.

[0045] The corn cob first passes through the feeding section of the peeling spiral roller 2, which is equipped with several metal awls 24. The top edge of the metal awls 24 has several alternating concave and convex arc-shaped protrusions. During rotation, these metal awls 24 cause the corn cob to tumble and lift the corn husk, causing the corn husk to loosen and wrinkle from its state of being attached to the surface of the corn kernel. A flexible roller 3 is set on one side of the peeling spiral roller 2, forming an inwardly rotating roller assembly with the peeling spiral roller 2. Two parallel rubber belts 20 are spirally wound on the peeling spiral roller 2, and several rubber nails 21 are installed on the rubber belts 20. The rubber nails 21 have perforated metal pieces 23 embedded inside, and side pads 22 (including a bottom piece and two side guards) are installed below them. They are fixed to the shaft of the peeling spiral roller 2 by screws, with the tail of the screw lower than the height of the rubber nail 21. When the corn cob enters between the flexible roller 3 and the peeling spiral roller 2, the surface of the flexible roller 3 contacts the inner side of the rubber belt 20, clamping the corn husk and pulling it downwards, thus peeling the corn. The rubber nails 21 provide additional friction during rotation, aiding in the peeling process. The rubber nails 21 have a perforated metal plate 23 built into them; when under force, the force is mainly concentrated on the perforated metal plate 23, reducing stress concentration and extending the service life of the rubber nails 21. The side pads 22 provide limiting and blocking force, reducing tearing damage caused by lateral displacement.

[0046] The material falls into the discharge auger mechanism: the peeled corn cobs and the removed corn husks fall into the discharge auger mechanism below. The specific process is the same as shown in Example 1.

[0047] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
