Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a spiral corn kernel lifting device carrying a dust removal fan. Background Technology
[0002] With the improvement of modern living standards, people's requirements for corn harvesting machinery are gradually increasing, and the demand for efficient and convenient corn harvesting methods is becoming increasingly urgent. In the post-harvest processing of corn, corn kernel lifting devices are commonly used equipment to lift corn kernels from a lower position to a higher position for subsequent storage, transportation, and other operations. Existing corn kernel lifting devices have some shortcomings. On the one hand, during the lifting process, various impurities, such as corn leaves, straw fragments, and dust, easily get mixed into the corn kernels. The presence of these impurities affects the quality of the corn kernels and their subsequent processing and utilization, reducing their economic value. On the other hand, the traditional structural design of lifting devices may result in low lifting efficiency and high energy consumption, which is not conducive to large-scale corn harvesting operations. Furthermore, the maintenance of existing lifting devices is often cumbersome, increasing operating costs and downtime. Utility Model Content
[0003] The purpose of this invention is to overcome the problems in the prior art and provide a spiral corn kernel lifting device with a dust removal fan.
[0004] The core concept of this invention is simultaneous lifting and cleaning, which is highly efficient, labor-saving, and saves energy and production costs. It uses a screw rod to horizontally transport corn kernels from a lower position and then vertically lift them up. Ingeniously, a fan blade is mounted on the same shaft above the lifting outlet, enclosed by a volute-shaped air duct. The fan generates a strong airflow when it rotates, blowing away any broken leaves and dust mixed in with the corn kernels directly through the adjacent waste discharge pipe, achieving simultaneous conveying and waste removal. The entire device is driven by a chain using the power from the peeling machine, eliminating the need for a separate power source and saving production costs. It is also designed as an easily disassembled modular unit, making it clean, convenient, and time-saving to use.
[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a spiral corn kernel lifting device with a dust removal fan, comprising a kernel horizontal conveying assembly, a lifting spiral assembly, a kernel storage assembly, and a frame;
[0006] The grain horizontal conveying assembly is fixed to the frame by a connecting plate. A sprocket is provided at the front end of the grain horizontal conveying assembly. The sprocket uses the power source of the peeling machine to realize the horizontal conveying of corn kernels.
[0007] The lifting screw assembly is connected to the rear end of the grain horizontal conveying assembly via the grain elbow assembly, and is used to lift the grain upwards. The lifting screw assembly includes a grain lifting auger, blower blades, and a grain blower housing. The grain lifting auger is located inside the grain lifting cylinder and is used to lift the grain spirally. The blower blades are coaxially mounted with the grain lifting auger and are located above the discharge port of the grain lifting cylinder. The grain blower housing covers the blower blades to form a volute air duct. When the blower blades rotate, they generate directional airflow, which can discharge impurities in the grains through the impurity discharge pipe of the grain blower housing.
[0008] Furthermore, the grain horizontal conveying assembly includes:
[0009] Conveyor box and transition channel located at its front end;
[0010] Horizontal auger for grains: This auger runs through the conveyor box and transition channel. It includes a horizontal grain shaft with helical blades welded onto it. This design effectively prevents material accumulation at the inlet, ensuring smooth entry of grains into the horizontal conveyor channel.
[0011] Sprockets: Installed at the front end of the horizontal auger for grain processing, they are used to receive external power and drive the horizontal shaft of the grain processing plant to rotate.
[0012] Furthermore, the grain horizontal auger also includes a dust cover and a grain spline shaft. The dust cover is used to seal the bearings and spline meshing parts, which can effectively prevent external dust and impurities from entering the key bearings and spline connections of the transmission parts, and extend the service life of these components.
[0013] Furthermore, the grain lifting auger includes:
[0014] Central tube and grain lifting blades welded onto it;
[0015] Feeding plate: Welded at an angle to the end of the central tube, used to guide and convey the grains into the grain discharge pipe;
[0016] Grain lifting auger disc: Located between the lifting section and the blower section, it is used to prevent grains from entering the grain blower housing. The diameter of the grain lifting auger disc is smaller than the inner diameter of the grain lifting cylinder. The inclined angle design of the feed plate facilitates the precise guidance of the lifted grains to the discharge pipe. While effectively preventing grains from entering the blower area, the disc's smaller diameter also provides a necessary flow channel for the impurity removal airflow generated by the blower.
[0017] Furthermore, the lifting spiral assembly also includes:
[0018] Rotary baffle: Hinged onto the grain discharge pipe, used to adjust the downward or backward discharge direction of the grains;
[0019] Sensor wheel: Mounted on the upper end of the bearing, it is used to detect the speed of the auger. The rotating baffle allows the discharge direction to be flexibly adjusted according to storage or subsequent processing requirements, while the sensor wheel facilitates real-time monitoring of the auger's operating status, providing a basis for equipment control and maintenance.
[0020] Furthermore, it also includes a power transmission system, which comprises a single-row chain, a transition sprocket assembly and a tension wheel assembly mounted on the frame. The single-row chain sequentially connects the vibrating screen sprocket assembly, the transition sprocket assembly, the tension wheel assembly and the sprocket. The sprocket borrows the power from the vibrating screen sprocket assembly through the single-row chain to achieve single-power drive for horizontal and vertical grain conveying. By utilizing the existing vibrating screen power source of the peeling machine or threshing machine and efficiently transmitting power with a single chain, it avoids configuring a separate power source for the lifting device, simplifies the structure and reduces energy consumption.
[0021] Furthermore, the inlet of the grain elbow assembly is connected to the rear end of the grain horizontal conveying component, and the outlet of the grain elbow assembly is connected to the bottom of the grain lifting cylinder. The grain elbow assembly is used to achieve unobstructed turning of the grain from horizontal conveying to vertical conveying.
[0022] The rear end of the horizontal auger and the lower end of the vertical auger are respectively equipped with sector gears. The two sector gears mesh inside the grain bend assembly. The meshing transmission of the sector gears inside the bend ensures the reliable transmission of power from the horizontal auger to the vertical auger. At the same time, the bend structure works together to prevent the grain from getting clogged when the conveying direction changes.
[0023] Furthermore, the grain blower housing is a tapered volute structure, and the impurity discharge pipe is installed on the grain blower housing. The tapered volute structure helps to guide and accelerate the airflow generated by the blower blades, forming a more concentrated and higher-velocity directional airflow, thereby more effectively blowing impurities away from the discharge pipe.
[0024] Furthermore, the fan blades include a fan bushing and multiple arc-shaped blades. The fan bushing is interference-fitted to the driven shaft head for seed lifting. The multiple arc-shaped blades are radially welded to the chassis. The interference fit ensures the firmness of the connection between the fan blades and the shaft head. The radially welded arc-shaped blades can generate a stable and sufficiently high airflow when rotating at high speed, meeting the requirements for efficient impurity removal.
[0025] Furthermore, the grain horizontal conveying assembly, the lifting screw assembly, and the grain storage assembly are connected by detachable bolts to form a modular maintenance unit. This modular connection method greatly facilitates the disassembly and assembly of the equipment, as well as the inspection, cleaning, or replacement of specific components, significantly improving the maintainability of the equipment.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0027] 1. Highly efficient integrated impurity removal function to improve grain purity.
[0028] By coaxially integrating fan blades and a tapered volute-type grain fan housing above the discharge port of the lifting screw assembly, a directional high-speed airflow is simultaneously generated during grain conveying. This airflow efficiently separates light impurities (such as broken leaves and dust) through the impurity discharge pipe, preventing impurities from mixing into the grain stream. Compared to traditional structures without impurity removal or with simple screens, this significantly improves grain purity, reduces subsequent processing burden, and directly enhances the quality and economic value of corn.
[0029] 2. The screw conveyor structure is stable, efficient, and highly adaptable.
[0030] Employing a horizontal and vertical double-helix conveying design (horizontal auger and lifting auger for grains), coupled with the unobstructed power transmission of the sector gears within the grain elbow assembly, continuous conveying of grains at 90° rotation is achieved. The helical blades are highly adaptable to both dry and wet grains, are not prone to clogging, and maintain stable conveying efficiency. The feed plate precisely guides the discharge, and the rotating baffle allows for flexible direction adjustment to meet different storage requirements, significantly improving the efficiency of large-scale operations.
[0031] 3. Power reuse optimizes energy consumption, and the transmission is simple and reliable.
[0032] The innovative design employs a single-row chain drive system, reusing the power of the peeling machine through the vibrating screen sprocket assembly, which drives the horizontal conveyor sprocket via a tensioning wheel and a transition sprocket. Simultaneously, the fan blades and the lifting auger work coaxially, eliminating the need for an additional power source. This design avoids the repetitive energy consumption of traditional multi-drive devices, significantly reducing energy consumption, simplifying the transmission structure, minimizing potential failure points, and substantially lowering operating costs.
[0033] 4. Modular design improves maintainability
[0034] The core components (horizontal conveyor assembly, lifting screw assembly, and storage assembly) are connected by detachable bolts, forming independent modular units. Key components such as bearings are equipped with dust covers to prevent impurities, and the splined shafts facilitate power disassembly and assembly. During maintenance, faulty modules can be quickly disassembled (e.g., replacing auger blades or cleaning elbows) without requiring the entire machine to be shut down, significantly reducing maintenance time and substantially improving equipment availability and lifespan.

[0042] 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 the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.
[0043] Example
[0044] like Figures 1-5 As shown, this embodiment provides a spiral corn kernel lifting device with a cleaning fan, including a kernel horizontal conveying assembly 1, a lifting spiral assembly 2, a kernel storage assembly 3, and a frame 4.
[0045] The horizontal grain conveying assembly 1 is fixed to the frame 4 via a connecting plate 7. A sprocket 10 is installed at the front end of the assembly, which utilizes the power source of the peeling machine to achieve horizontal conveying of corn kernels. The horizontal grain conveying assembly 1 includes a horizontal grain auger 9, a conveying box 5, and a transition channel 8 at its front end. The horizontal grain auger 9 passes through the conveying box 5 and the transition channel 8. The horizontal grain auger 9 includes a horizontal grain shaft 11 with spiral blades 12 welded to it. This structural design effectively prevents material accumulation at the inlet, ensuring smooth entry of kernels into the horizontal conveying channel. The sprocket 10 is installed at the front end of the horizontal grain auger 9, receiving external power to drive the horizontal grain shaft 11 to rotate. The horizontal grain auger 9 also includes a dust cover 14 and a grain spline shaft 15. The dust cover 14 seals the bearings and spline meshing parts, effectively preventing external dust and impurities from entering the critical bearings and spline connections of the transmission parts, extending the service life of these components.
[0046] The lifting screw assembly 2 is connected to the rear end of the grain horizontal conveying assembly 1 via the grain elbow assembly 16, and is used to lift the grain upward. The lifting screw assembly 2 includes a grain lifting auger 17, a blower blade 18 and a grain blower housing 21. The grain lifting auger 17 is located inside the grain lifting cylinder 19 and is used to spirally lift the grains. The grain lifting auger 17 includes a central tube 25, grain lifting blades 27, a material guide plate 28, and a grain lifting auger disc 29. The grain lifting blades 27 are welded to the central tube 25, and the material guide plate 28 is inclinedly welded to the end of the central tube 25 to guide and convey the grains to the grain discharge pipe 39. The grain lifting auger disc 29 is located between the lifting section and the blower section to prevent the grains from continuing to rise and entering the grain blower housing 21. The diameter of the grain lifting auger disc 29 is smaller than the inner diameter of the grain lifting cylinder 19. The inclined angle design of the material guide plate 28 facilitates the precise guidance of the lifted grains to the grain discharge pipe 39. While effectively preventing the grains from entering the blower area, the smaller diameter of the grain lifting auger disc 29 also provides a necessary flow channel for the impurity removal airflow generated by the blower. The blower blades 18 are coaxially mounted with the grain lifting auger 17 and located above the discharge port of the grain lifting cylinder 19. The grain blower housing 21 covers the blower blades 18 to form a volute air duct. When the blower blades 18 rotate, they generate directional airflow, which discharges impurities in the grain through the impurity discharge pipe 38 of the grain blower housing 21.
[0047] The lifting screw assembly 2 also includes a rotating baffle 20 and a sensor wheel 24. The rotating baffle 20 is hinged to the grain discharge pipe 39, the inlet of which is connected to the outlet of the grain lifting cylinder 19. The grain discharge pipe 39 has two outlets. The rotating baffle 20 is used to adjust the downward or backward discharge direction of the grain discharge pipe 39. The sensor wheel 24 is mounted on the upper end of the bearing 23 and is used to detect the speed of the auger. The rotating baffle 20 allows the discharge direction to be flexibly adjusted according to storage or subsequent processing requirements, while the sensor wheel 24 facilitates real-time monitoring of the auger's operating status, providing a basis for equipment control and maintenance.
[0048] This corn kernel lifting device also includes a power transmission system, which includes a single-row chain 37, a transition sprocket assembly 36 and a tension wheel assembly 35 mounted on the frame 4. The single-row chain 37 sequentially connects the vibrating screen sprocket assembly 34, the transition sprocket assembly 36, the tension wheel assembly 35 and the sprocket 10. The sprocket 10 borrows the power of the vibrating screen sprocket assembly 34 through the single-row chain 37 to achieve single-power drive for horizontal and vertical kernel conveying. By borrowing the existing vibrating screen power source of the peeling machine or threshing machine and efficiently transmitting power through the single-row chain 37, it avoids configuring a separate power source for the lifting device, simplifies the structure and reduces energy consumption.
[0049] The inlet of the grain elbow assembly 16 is connected to the rear end of the grain horizontal conveying component 1, and the outlet of the grain elbow assembly 16 is connected to the bottom of the grain lifting cylinder 19. The grain elbow assembly 16 is used to realize the unobstructed turning of the grain from horizontal conveying to vertical conveying. The rear end of the grain horizontal auger 9 and the lower end of the grain lifting auger 17 are respectively provided with sector gears. The two sector gears mesh in the grain elbow assembly 16. The meshing transmission of the sector gears in the grain elbow assembly 16 ensures the reliable transmission of power from the horizontal auger to the vertical lifting auger. At the same time, the elbow structure works together to prevent the grain from getting blocked when the conveying direction changes by 90 degrees.
[0050] The grain blower housing 21 has a tapered volute structure, and the impurity discharge pipe 38 is located on the grain blower housing 21. The tapered volute structure helps guide and accelerate the airflow generated by the blower blades, forming a more concentrated and higher-velocity directional airflow, thereby more effectively blowing impurities away from the discharge pipe. The blower blades 18 include a blower bushing 31 and multiple arc-shaped blades 32. The blower bushing 31 is interference-fitted to the grain lifting driven shaft head 30; the multiple arc-shaped blades 32 are radially welded to the chassis 33. The interference fit ensures the firm connection between the blower blades 18 and the grain lifting driven shaft head 30. The radially welded arc-shaped blades 32 can generate a stable and sufficiently high-pressure airflow when rotating at high speed, meeting the requirements for efficient impurity removal.
[0051] The grain horizontal conveying assembly 1, the lifting screw assembly 2, and the grain storage assembly 3 are connected by detachable bolts to form a modular maintenance unit. This modular connection method greatly facilitates the disassembly and assembly of the equipment, as well as the inspection, cleaning, or replacement of specific parts, significantly improving the maintainability of the equipment.
[0052] The working process of this device is as follows: Corn kernels fall from the harvesting component into the conveying box 5 of the horizontal kernel conveying assembly 1. The front sprocket 10 uses the power of the peeling machine to drive the horizontal kernel auger 9 to rotate, and its spiral blades 12 push the kernels horizontally to the rear end. The kernels achieve a 90° turn through the kernel elbow assembly 16: the sector gears inside the elbow mesh to transmit power to the vertical kernel lifting auger 17, simultaneously completing the change of kernel flow direction and avoiding blockage.
[0053] After the grains enter the lifting screw assembly 2, they are spirally conveyed upwards along the grain lifting cylinder 19 by the grain lifting blades 27. Upon reaching the top, the grain lifting auger disc 29 prevents them from entering the blower area, and the inclined material guide plate 28 directs the grains to the grain discharge pipe 39. At this time, the coaxially mounted blower blades 18 rotate at high speed, forming a directional high-speed airflow within the grain blower housing 21 with a tapered volute structure. This airflow powerfully removes mixed light impurities such as broken leaves and dust through the impurity discharge pipe 38, achieving simultaneous impurity removal during conveying.
[0054] Pure kernels fall through discharge pipe 39, and the user can adjust the direction via hinged rotating baffle 20: falling downwards into kernel storage assembly 3, or backwards into ear box. The entire process is powered solely by a single-row chain 37 reusing the power of the peeling machine's vibrating screen. Sensor wheel 24 monitors the auger speed in real time to ensure stable operation.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
