Description

Technical Field

[0001] This utility model relates to the field of corn harvesting, and in particular to a high-volume fresh corn residue crushing and cleaning device. Background Technology

[0002] Fresh corn is loved by consumers for its sweet taste and rich nutrition, and occupies an important position in the food processing industry. In the processing of fresh corn, such as harvesting, peeling and threshing, a lot of waste is generated, such as corn husks, corn silks and corn cob fragments. If these wastes are not dealt with in time, they will not only occupy space, but may also breed bacteria and cause pests, affecting the hygiene and safety of the processing environment.

[0003] In existing technologies, the harvesting of fresh sweet corn has strict time requirements, usually during the milk stage. At this stage, the corn kernels are tender, have a high moisture content, and a relatively fragile outer skin, making them easily damaged. After harvesting, fresh sweet corn needs to undergo a waste cleaning process to remove impurities, residual leaves, broken ears, etc., from the ears to ensure product quality. However, existing cleaning devices are often designed with the cleaning needs of ordinary corn in mind, and do not adequately consider the special case of fresh sweet corn. During the cleaning process, when existing cleaning devices come into contact with the ears, the lack of targeted protective measures and precise operation control easily damages the ears. For the tender kernels of fresh sweet corn, such collisions and friction can easily lead to kernel breakage, deformation, or even detachment. Once the ears are damaged, it will not only affect the appearance quality of the fresh sweet corn and reduce its market value, but also necessitates the development of a high-volume fresh sweet corn waste crushing and cleaning device to solve the above problems. Utility Model Content

[0004] To overcome the problem that direct contact cleaning of tender corn ears during the milk stage can damage them.

Detailed Implementation

[0022] Fresh corn, a popular agricultural product among consumers, holds a significant position in the food processing industry due to its unique sweet and delicious taste and rich and diverse nutritional components. With the improvement of people's living standards and increased health awareness, the market demand for fresh corn continues to grow. It can be used directly as a fresh ingredient for cooking, or processed into a variety of delicious foods such as corn juice, canned corn, and corn chips, satisfying the diverse taste preferences of consumers.

[0023] In the processing of fresh corn, harvesting, husking, and threshing are essential steps. However, while these steps bring high-efficiency production, they also create a thorny problem—the generation of a large amount of waste. This waste mainly includes corn husks, corn silk, and corn cob fragments. Corn husks, the layers of green outer covering the corn cob, often separate from the cob after harvesting, becoming part of the waste; corn silk, long and soft, easily scatters during the husking process; and corn cob fragments are formed during threshing when the corn cob is broken into small particles by mechanical action.

[0024] If these waste materials are not handled promptly, they will lead to a series of serious consequences. First, they will occupy a large amount of processing space. During the peak season for fresh corn processing, large amounts of straw and other waste materials pile up, making the already limited processing space even more crowded. This not only affects the proper placement of processing equipment and the movement of operators, but also reduces the efficiency of the entire processing flow. Imagine a small processing workshop filled with piles of corn husks and corn cob fragments; workers moving around in this environment will not only find it difficult to move, but will also be prone to collisions and other safety accidents.

[0025] Secondly, these scraps are highly susceptible to bacterial growth and pest infestation. Corn husks and silks contain abundant moisture and nutrients, providing an ideal environment for bacterial reproduction. Under warm and humid conditions, bacteria multiply rapidly, producing unpleasant odors that not only affect air quality in the processing environment but may also contaminate the fresh corn being processed, reducing product quality and safety. Simultaneously, corn cob fragments and other scraps easily attract various pests, such as cockroaches and rats. These pests not only feed on stalks and other scraps but may also spread diseases, posing a threat to the processing environment and the health of employees. Once pests invade processing equipment or storage areas, they may damage the equipment, affecting its normal operation and increasing maintenance costs.

[0026] More seriously, the presence of these straw and other waste products can severely impact the hygiene and safety of the processing environment. A poorly hygienic processing environment not only fails to guarantee the quality of fresh corn products but may also violate relevant food safety regulations. In today's era where consumers are highly concerned about food safety, any hygiene issue can damage a company's reputation and even lead to legal action. Therefore, effectively handling the waste products generated during fresh corn processing has become a crucial issue that fresh corn processing companies urgently need to address.

[0027] To address this challenge, researchers and enterprise technicians have worked tirelessly to develop a high-volume fresh corn impurity crushing and cleaning device. This device has brought new hope to fresh corn processing enterprises and has become a key tool for solving the impurity problem.

[0028] The high-volume fresh corn waste crushing and cleaning device operates on the principle of advanced airflow crushing and cleaning technology. When waste generated during fresh corn processing is conveyed into the device, it first enters the crushing zone. Here, high-speed rotating crushing blades powerfully cut and break down the waste. Relatively soft waste such as corn husks and silks are quickly shredded, while harder waste such as corn cob fragments are further broken into smaller particles. This crushing process not only reduces the volume of waste, facilitating subsequent processing, but also disrupts the living environment of bacteria and insect eggs that may be present in the waste, reducing the breeding of bacteria and pests at the source.

[0029] After being crushed, the impurities enter the cleaning area. At this point, the device activates a high-volume airflow system. The powerful airflow separates the crushed impurity particles according to their different densities and weights. Lighter corn silk fragments and some fine corn husk fragments are carried to the top of the device by the airflow and collected through a dedicated collection pipe; while heavier corn cob fragments and other impurities settle to the bottom of the device due to gravity and are discharged through another collection port. This airflow-based cleaning principle efficiently separates different components from the impurities, achieving fine processing of the impurities.

[0030] This device boasts numerous significant advantages. Firstly, its high-volume airflow design greatly enhances processing efficiency. During peak fresh corn processing seasons, large quantities of impurities can be crushed and cleaned in a short time, preventing accumulation and ensuring smooth processing. Compared to traditional impurity handling methods, this device offers several times the processing speed, meeting the production needs of large-scale fresh corn processing enterprises.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please seeFigure 1 - Figure 5 This utility model provides an embodiment: a high-volume fresh corn impurity crushing and cleaning device, including an impurity inlet 1, a fan housing 21 fixedly connected to the impurity inlet 1, a support frame 22 disposed on the fan housing 21, fastening bolts 23 threadedly connected to the fan housing 21, a motor body 24 fixedly connected to the support frame 22, a coupling body 25 disposed at the output end of the motor body 24, a second rotating shaft 27 disposed on the coupling body 25, a transmission assembly disposed on the fan housing 21, a first rotating shaft 26 rotatably connected to the fan housing 21, a second crushing blade 29 fixedly connected to the first rotating shaft 26, a first crushing blade 28 fixedly connected to the first rotating shaft 26, a fan impeller body 210 fixedly connected to the first rotating shaft 26, and a fan blade body 21 fixedly connected to the first rotating shaft 26. 1. A guide assembly is provided on the fan housing 21. The second rotating shaft 27 is rotatably connected to the fan housing 21. The transmission assembly drives the first rotating shaft 26 and the second rotating shaft 27 to rotate synchronously. The guide assembly guides the discharged impurities. In use, the motor body 24 drives the first rotating shaft 26 and the second rotating shaft 27 to rotate after being transmitted through the coupling body 25 and the transmission assembly. When the first rotating shaft 26 rotates, it drives the fan blade body 211 to rotate, generating suction force, which draws straw and other impurities into the fan housing 21 through the impurity suction port 1. When passing through the impurity suction port 1, the rotation of the first rotating shaft 26 and the second rotating shaft 27 drives the first crushing blade 28 and the second crushing blade 29 to crush the straw and other impurities. After crushing, the guide assembly guides the straw and other impurities to be discharged evenly, thereby improving the recycling rate of returning straw to the field.

[0033] Please see Figure 1 - Figure 3In this embodiment, the support frame 22 has through holes at the relative positions of the fastening bolts 23. The fastening bolts 23 pass through the through holes and are threadedly connected to the fan housing 21. The support frame 22 is fixed by the fastening bolts 23 through the threaded connection between the support frame 22 and the fan housing 21. The first rotating shaft 26 has through holes inside, and the second rotating shaft 27 passes through the through holes and is rotatably connected to the fan housing 21. During use, the rotation of the first rotating shaft 26 and the second rotating shaft 27 drives the first crushing blade 28 and the second crushing blade 29 to rotate, crushing the impurities and discharging them for return to the field. The transmission assembly includes a fixed outer shell 212 fixedly connected to the fan housing 21, a first bevel gear 213 fixedly connected to the second rotating shaft 27, and a second bevel gear 214 meshing with the first bevel gear 213. A third bevel gear 215 meshes with the second bevel gear 214. The first bevel gear 213 is rotatably connected to the fixed housing 212, the second bevel gear 214 is rotatably connected to the fixed housing 212, and the third bevel gear 215 is fixedly connected to the first rotating shaft 26. Through the cooperation of the first bevel gear 213, the second bevel gear 214 and the third bevel gear 215, the first rotating shaft 26 and the second rotating shaft 27 rotate in a mirror image, thereby driving the first crushing blade 28 and the second crushing blade 29 to cut the debris. The fixed housing 212 has a limiting groove at the relative position of the second bevel gear 214. The second bevel gear 214 is rotatably connected to the groove, and the rotation of the second bevel gear 214 is restricted by the groove to prevent the second bevel gear 214 from disengaging from the fixed housing 212.

[0034] Please see Figure 1 , Figure 4 - Figure 5In this embodiment, the guiding assembly includes a first motor 31 fixedly connected to the fan housing 21, a rotating disk 32 fixedly connected to the output end of the first motor 31, a first fixed rod 33 fixedly connected to the rotating disk 32, a sliding rack 34 slidably connected to the fan housing 21, a connecting block 37 fixedly connected to the sliding rack 34, and a rotating gear 35 meshing with the sliding rack 34. The first fixed rod 33 is slidably connected to the connecting block 37, and the guide plate 36 is rotatably connected to the fan housing 21. The first fixed rod 33 and the connecting block 37 cooperate to drive the sliding rack 34 to slide back and forth, and the sliding rack 34 and the rotating gear 35 cooperate to drive the guide plate 36 to swing. The guide plate 36 guides the discharged material. The guide plate 36 swings to guide the discharged waste, increasing its discharge diffusion area and improving the subsequent utilization rate of returning it to the field. The fan casing 21 has a groove at the relative position of the sliding rack 34. The sliding rack 34 is slidably connected to the groove. The groove guides the sliding of the sliding rack 34 to prevent it from tilting during sliding, which would affect the meshing of the sliding rack 34 with the rotating gear 35. The connecting block 37 has a limiting groove at the relative position of the first fixed rod 33. The first fixed rod 33 is slidably connected to the groove. The groove restricts the sliding of the first fixed rod 33 to prevent it from disengaging from the connecting block 37. The first fixed rod 33 and the connecting block 37 cooperate to drive the sliding rack 34 to slide back and forth.

[0035] During operation, the motor body 24 drives the second shaft 27 to rotate via the coupling body 25. The rotation of the second shaft 27 drives the first bevel gear 213 to rotate, which in turn drives the second bevel gear 214 to rotate on the fixed housing 212. The rotation of the second bevel gear 214 drives the third bevel gear 215 to rotate, which in turn drives the connected first shaft 26 to rotate. The rotation of the first shaft 26 drives the fan blade body 211 to rotate, generating suction that draws straw and other debris into the fan housing 21 through the debris inlet 1. The first crushing blade 28 and the second crushing blade 29, driven by the rotation of the first rotating shaft 26 and the second rotating shaft 27, crush straw and other impurities. When the crushed material is discharged, the first motor 31 works to drive the rotating disk 32 to rotate. When the rotating disk 32 rotates, it drives the first fixed rod 33 to move. When the first fixed rod 33 moves, it cooperates with the connecting block 37 to drive the sliding rack 34 to slide back and forth. When the sliding rack 34 slides, it meshes with the rotating gear 35 and drives the guide plate 36 to swing back and forth, thereby guiding the discharged material and making the material sprayed more evenly and widely, thus increasing the utilization rate of returning to the field.

[0036] Through the above steps, suction is generated by the high-speed rotation of the fan impeller body 210 and the fan blade body 211 during use, and the first crushing blade 28 and the second crushing blade 29 are used to chop up straw and other debris. This solves the problem that direct contact cleaning of corn ears will damage the corn ears when the corn is tender during the milk stage of harvest.
