Description

Technical Field

[0001] This utility model relates to the field of harvester technology, and in particular to a potato harvester with soil-potato separation function. Background Technology

[0002] Currently, most potato harvesters focus on digging potatoes out of the soil, but are inadequate in soil-potato separation and potato size screening. Manual screening is inefficient and lacks precision, consuming significant manpower and resources. Existing mechanical screening devices, on the one hand, cannot efficiently and thoroughly separate soil from potatoes during soil-potato separation, leaving residual soil that affects potato quality and subsequent storage. On the other hand, their ability to screen potatoes by size is limited, failing to meet market demand for potatoes of different sizes.

[0003] Furthermore, traditional harvesters lack flexibility during the screening process and cannot adjust screening parameters in a timely manner according to the actual harvest situation. Therefore, it is urgent to develop a harvester with efficient potato-soil separation capabilities that can flexibly and accurately screen potatoes of different sizes to improve potato harvesting efficiency and quality and meet the needs of modern potato industry development.

[0004] The traditional potato harvester with soil-potato separation function has not solved the problem. Therefore, we propose a potato harvester with soil-potato separation function. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a potato harvester with soil-potato separation function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A potato harvester with a soil-potato separation function includes a mounting base and a screening assembly. The screening assembly is fixedly connected to the top of the mounting base. The screening assembly includes two E-shaped frames. Three mounting rings are fixedly connected to the middle of three sets of opposing columns on both sides of the two E-shaped frames. Three rotating inner rings are rotatably connected inside the three mounting rings. A rotating drum is fixedly connected inside the three rotating inner rings. Multiple sets of holes are opened around the inner wall of the rotating drum. A trapezoidal frame is fixedly connected to one side of the two E-shaped frames. A trapezoidal guide funnel is fixedly connected to the top of the trapezoidal frame near the two E-shaped frames. Multiple support nails are fixedly connected to the upper surface of the trapezoidal frame near the trapezoidal guide funnel.

[0007] As a further improvement of this utility model: a sliding groove is provided on the side of the upper surface of the trapezoidal frame away from the multiple support nails, and multiple sliders are slidably connected inside the sliding groove, and multiple T-shaped guide plates are fixedly connected to the top of the multiple sliders.

[0008] By creating grooves on the upper surface of the trapezoidal frame and allowing the slider to slide within the grooves, the T-shaped guide plate can be flexibly repositioned, facilitating the adjustment of its tilt angle according to the size of the potatoes, thus achieving the purpose of sorting and rolling potatoes by size.

[0009] As a further embodiment of this utility model: the ends of the multiple T-shaped guide plates away from the multiple sliders pass through the surfaces of multiple support nails, and three storage compartments are slidably connected inside the trapezoidal frame.

[0010] The T-shaped guide plate extends through the surface of the support nail at one end, allowing it to rotate around the support nail as a fulcrum. This, combined with position adjustments, guides potatoes of different sizes. The three slidingly connected storage compartments inside the trapezoidal frame effectively provide storage space for sorted potatoes, facilitating the collection of potatoes of different sizes and achieving orderly storage.

[0011] As a further improvement of this invention: the multiple sets of holes are distributed with increasing density from left to right, and two gear rings are fixedly connected to the surface of the rotating roller on both sides of the three inner rotating rings on the outer wall of the rotating roller. The multiple sets of holes are distributed with increasing density from left to right. As the rotary drum rotates, it effectively separates soil particles according to their size, allowing them to pass through holes of varying densities and be screened out more precisely, thus improving the screening efficiency. The two gear rings on the surface of the rotary drum, in conjunction with other transmission components, provide a power transmission path for the drum's rotation, ensuring stable rotation and continuous screening operations.

[0012] As a further improvement of this utility model, a soil discharge hole is provided on the upper surface of the mounting base at the lower end of the three mounting rings. Two support frames are fixedly connected to the left and right sides of the upper surface of the soil discharge hole. A drive motor is fixedly connected to one side of the support frame. The output end of the drive motor is rotatably connected to two rotating shafts through a coupling.

[0013] A discharge hole is provided on the mounting base to facilitate the removal of screened soil, ensuring proper cleaning and normal machine operation. Two support frames on the discharge hole provide support for other components. The drive motor is connected to the rotating shaft via a coupling, transmitting power from the motor to the shaft to drive subsequent transmission components and power the entire screening rotation system.

[0014] As a further embodiment of this utility model: a rotating column is rotatably connected to the middle of the two rotating shafts, and a driving gear is rotatably connected to the surface of the rotating column and at a position perpendicular to the two gear rings, and the lower ends of the two gear rings mesh with the upper ends of the two driving gears.

[0015] The rotating shaft drives the rotating column to rotate, which in turn drives the drive gear fixed on the surface of the rotating column to rotate. The drive gear meshes with the gear ring, effectively transmitting power from the rotating shaft to the rotating drum, facilitating the rotation of the rotating drum and achieving the purpose of making the rotating drum perform screening work in a predetermined manner.

[0016] As a further improvement of this utility model: two sets of moving wheels are provided at the lower end of the mounting base, the moving wheels having the ability to be controlled and moved with the cab; a bulldozing conveyor belt is provided at the top of the trapezoidal guide funnel away from the trapezoidal frame mounting base, the bulldozing conveyor belt is GRiMME SE150 / 170-60; and a controller is fixedly connected to the surface of the mounting base. The operator in the cab controls the entire harvester's direction and speed, allowing for flexible operation in the field and adaptability to different field environments and operational needs. The bulldozing conveyor belt (GRiMME SE150 / 170-60) at the top of the trapezoidal guide funnel effectively transports the soil and potato mixture to the funnel, facilitating material input for subsequent screening and ensuring a smooth harvesting process.

[0017] Compared with the prior art, this utility model provides a potato harvester with soil-potato separation function, which has the following beneficial effects: 1. In this utility model, the opening of the holes in the inner wall of the drum and the coordinated operation of the drive gear driving the gear ring, the mounting ring and the rotating inner ring are the key to achieving soil-potato separation and ensuring stable rotation of the drum in this potato harvester.

[0018] The inner wall of the drum has multiple sets of holes, which gradually increase in density from left to right. As the drum rotates, the soil and potatoes come into contact with the inner wall under centrifugal force. This design of varying hole density allows soil particles of different sizes to be ejected from the drum sequentially through these holes, achieving precise sieving based on particle size. This facilitates effective separation of soil and potatoes, improving both the efficiency and quality of soil-potato separation.

[0019] The drive gear meshes with the gear ring. When the drive motor rotates the shaft and the rotating column, the drive gear, fixed to the surface of the rotating column, rotates accordingly. The rotation of the drive gear, through meshing with the gear ring, transmits power to the gear ring, which in turn drives the connected rotating drum. Simultaneously, the inner rotating ring is embedded within the mounting sleeve, which provides stable support for the inner rotating ring. Through the cooperation between the drive gear and the gear ring, and the structural design between the mounting sleeve and the inner rotating ring, a stable driving force and support force are effectively provided for the rotating drum, ensuring its stability during high-speed rotation and guaranteeing continuous and reliable screening operations.

[0020] In summary, the scientifically designed holes in the inner wall of the drum enable effective screening of soil and potatoes. The coordinated design of the drive gear, gear ring, mounting ring, and rotating inner ring ensures the stability of the drum during rotation. This allows the device to efficiently screen soil and potatoes, providing strong support for the entire potato harvesting process.

[0021] 2. In this utility model, the T-shaped guide plate fixedly connected to the top of the trapezoidal frame and the storage trough designed inside the trapezoidal frame play a key role in screening potatoes of different sizes in this potato harvester with soil-potato separation function.

[0022] The T-shaped guide plate at the top of the trapezoidal frame has one end connected to a slider, allowing it to move within a groove, and the other end passing through the surface of a support pin. Workers push the slider, causing the T-shaped guide plate to rotate around the support pin. This allows for flexible adjustment of the T-shaped guide plate's tilt angle. Potatoes of different sizes roll along the T-shaped guide plate at varying tilt angles under gravity. Larger potatoes may require a gentler tilt angle to roll, while smaller potatoes roll at a steeper angle. This adjustable T-shaped guide plate design effectively guides the rolling path of potatoes based on their size, facilitating the initial separation of potatoes of different sizes and preparing them for subsequent sizing.

[0023] The trapezoidal rack has three storage compartments inside. After potatoes of different sizes are initially separated by the T-shaped guide plate, they fall into their respective storage compartments. This design of the storage compartments, in conjunction with the screening function of the T-shaped guide plate, effectively provides specific storage space for potatoes of different sizes, facilitating the classification and collection of potatoes of different specifications, and ultimately achieving the goal of screening potatoes according to size.

[0024] In summary, the T-shaped guide plate at the top of the trapezoidal frame allows for flexible adjustment of the tilt angle, guiding the rolling path of the potatoes. The internal storage compartments of the trapezoidal frame facilitate the classification and collection of potatoes of different sizes. This enables the device to easily adjust screening conditions and effectively screen potatoes of different sizes, improving the efficiency and accuracy of sieving according to specifications during potato harvesting.

[0025] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0030] Example: Reference Figures 1 to 4 A potato harvester with a soil-potato separation function includes a mounting base 1 and a screening component 2. The screening component 2 is fixedly connected to the top of the mounting base 1. The screening component 2 includes two E-shaped frames 201. Three mounting collars 202 are fixedly connected to the middle of three sets of opposing columns on both sides of the two E-shaped frames 201. Three rotating inner rings 203 are rotatably connected inside the three mounting collars 202. A rotating drum 204 is fixedly connected inside the three rotating inner rings 203. Multiple sets of holes 206 are opened around the inner wall of the rotating drum 204. A trapezoidal frame 207 is fixedly connected to one side of the two E-shaped frames 201. A trapezoidal guide funnel 208 is fixedly connected to the top of the trapezoidal frame 207 near the two E-shaped frames 201. Multiple support nails 209 are fixedly connected to the upper surface of the trapezoidal frame 207 near the trapezoidal guide funnel 208.

[0031] A slide groove 210 is provided on the side of the upper surface of the trapezoidal frame 207 away from the multiple support nails 209. Multiple sliders 211 are slidably connected inside the slide groove 210, and multiple T-shaped guide plates 213 are fixedly connected to the top of each slider 211.

[0032] Multiple T-shaped guide plates 213 have one end away from multiple sliders 211 that passes through the surface of multiple support pins 209, and three storage compartments 214 are slidably connected inside the trapezoidal frame 207.

[0033] Multiple sets of holes 206 are distributed from left to right in a gradually increasing density pattern. Two gear rings 215 are fixedly connected to the surface of the rotating roller 204 on both sides of the three rotating inner rings 203 on the outer wall of the rotating roller 204.

[0034] A soil discharge hole 216 is provided on the upper surface of the lower end of the mounting base 1, which is perpendicular to the three mounting collars 202. Two support frames 217 are fixedly connected to the left and right sides of the upper surface of the soil discharge hole 216. A drive motor 218 is fixedly connected to one side of the support frame 217. The output end of the drive motor 218 is rotatably connected to two rotating shafts 220 through a coupling 219. Two rotating shafts 220 are rotatably connected to a rotating column 221 in the middle. A drive gear 222 is rotatably connected to the surface of the rotating column 221 and at a position perpendicular to the two gear rings 215. The lower ends of the two gear rings 215 mesh with the upper ends of the two drive gears 222.

[0035] In this embodiment, the T-shaped guide plate 213 fixedly connected to the top of the trapezoidal frame 207 in the screening assembly 2 is ingeniously designed. One end of the T-shaped guide plate 213 is connected to the slider 211 that slides within the chute 210, and the other end passes through the support pin 209. When the operator pushes the slider 211, the chute 210 guides the slider 211, enabling the T-shaped guide plate 213 to rotate around the support pin 209. This operation method effectively allows for flexible adjustment of the tilt angle of the T-shaped guide plate 213, facilitating the provision of rolling tracks with different inclinations based on potato size differences, thus achieving the initial effect of differentiating the rolling paths of potatoes by size. Due to their own gravity and rolling characteristics, potatoes of different sizes will exhibit different rolling states on the T-shaped guide plate 213 at different tilt angles, thereby achieving preliminary screening.

[0036] The storage compartments inside the trapezoidal frame 207 are an indispensable part of the screening component 2. After the potatoes undergo preliminary screening by the T-shaped guide plate 213, potatoes of different sizes fall into the three storage compartments inside the trapezoidal frame 207 along their respective rolling paths. Through the close cooperation between these storage compartments and the screening function of the T-shaped guide plate 213, dedicated storage spaces are provided for potatoes of different sizes, facilitating the precise collection of potatoes after preliminary sorting according to size specifications, ultimately achieving the goal of comprehensively screening potatoes according to different size specifications.

[0037] refer to Figure 1 The mounting base 1 has two sets of moving wheels 3 at its lower end. The moving wheels 3 are capable of being controlled and moved with the cab 5. The trapezoidal guide funnel 208 is away from the trapezoidal frame 207. The top of the mounting base 1 is equipped with a bulldozing conveyor belt 4. The bulldozing conveyor belt 4 is GRiMME SE150 / 170-60. The controller 5 is fixedly connected to the surface of the mounting base 1.

[0038] In this embodiment, the driver operates the machine from inside the cab 5, which enables control over the direction and speed of the entire harvester, facilitating flexible operation of the harvester in the field and achieving the goal of adapting to different field environments and operational needs.

[0039] Working principle: Before using the potato harvester with soil-potato separation function, the operator first turns on the harvester via the controller (position 5) to prepare for its operation. Simultaneously, other operators insert the three storage compartments (position 214) into the trapezoidal frame (position 207) in an orderly manner, preparing for subsequent potato collection.

[0040] After preparation, the machine is started. The rolling wheels 3 at the lower end of the mounting base 1 move the entire structure on top of the mounting base 1, allowing the harvester to move through the field. The bulldozing conveyor 4 at the front of the machine begins operation, transporting the soil and potato mixture to the trapezoidal guide funnel 208. The trapezoidal guide funnel 208, using its shape and position design, guides the mixture into the rotating drum 204.

[0041] At this time, the drive motor 218 starts running, and the output end of the motor drives the rotating shaft 220 to rotate through the coupling 219. The rotating shaft 220 further drives the rotating column 221 to rotate. The rotation of the rotating column 221 causes the drive gear 222 fixed on its surface to rotate as well. Since the drive gear 222 meshes with the gear rings 215 on both sides of the rotating drum 204, the rotation of the drive gear 222 drives the gear rings 215 to rotate, thereby driving the rotating drum 204 to rotate around its own axis. In this process, the rotating inner ring 203 is embedded inside the mounting collar 202. Through the cooperation of the two, the stability of the rotating drum 204 during rotation is ensured, which effectively provides support for the smooth operation of the rotating drum 204, facilitates continuous and efficient screening, and achieves the purpose of improving screening efficiency and quality.

[0042] During rotation, the rotating drum 204 uses centrifugal force to separate the soil and potatoes. Because the inner wall of the rotating drum 204 has multiple sets of holes 206 arranged from left to right with increasing density, the soil is thrown out of the rotating drum 204 through these holes 206 under centrifugal force and falls to the ground through the soil discharge holes 216 perpendicular to the upper surface of the mounting base 1 at the lower end of the mounting ring 202, thus achieving initial separation of the soil and potatoes. The potatoes remain inside the rotating drum 204 and subsequently enter the middle of multiple T-shaped guide plates 213 installed at the top of the trapezoidal frame 207.

[0043] Workers adjust the position of a T-shaped guide plate 213 fixed to the top of the slider 211 by pushing the slider 211 within the chute 210. The end of the T-shaped guide plate 213 furthest from the slider 211 passes through the surface of the support pin 209. When the slider 211 pushes the T-shaped guide plate 213, the T-shaped guide plate 213 rotates around the support pin 209. In this way, workers can adjust the tilt angle of the T-shaped guide plate 213 according to the size of the potatoes, allowing potatoes of different sizes (large, medium, and small) to roll along the T-shaped guide plate 213 separately, thus classifying the potatoes by size. Finally, the classified potatoes roll into the corresponding storage bin 214 for collection.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
