Description

Technical Field

[0001] This invention relates to the field of agricultural technology, specifically to a peanut cleaning device and cleaning method. Background Technology

[0002] Peanuts, as an important economic crop and oilseed crop, play a vital role in the food industry through their processed products. In the initial stages of peanut processing, cleaning is an essential and crucial step, especially in the mechanical processing of edible tubers / fruits. The core of this process lies in cleaning, which aims to remove the large amounts of dirt, sand, plant stems, and leaves that adhere to the peanuts during harvesting, drying, and transportation, providing clean raw materials for subsequent drying, shelling, oil extraction, or food processing. Therefore, efficient and reliable peanut cleaning equipment, as a type of batch processing equipment for fruits or vegetables, is of paramount practical significance for ensuring final product quality, improving processing efficiency, and achieving food safety in production.

[0003] Referring to Chinese invention patent publication number CN 210869794 U, entitled "A Peanut Cleaning Device and Peanut Processing Equipment," its key technical features are: the cleaning device includes a base, a cleaning tank is provided above the base, a second support is connected to the center of the bottom surface of the cleaning tank, a protrusion is installed in the center of the upper surface of the base, the second support and the protrusion are hinged together by a second rotating shaft, the cleaning tank has an open top structure, drainage holes are provided on the side and bottom walls of the cleaning tank, a nozzle is provided above the cleaning tank, a support rod is installed on the right side of the upper surface of the base, the nozzle is installed on the support rod, and a drive assembly is also provided on the base. This peanut cleaning device, through the cooperation of a motor, a rotating disc, a third rotating shaft, a connecting rod, a first rotating shaft, a first support, a cleaning tank, a second support, a second rotating shaft, and a protrusion, can drive the cleaning tank to swing back and forth, resulting in better cleaning of peanuts in the cleaning tank, reducing labor intensity, and achieving high cleaning efficiency and speed.

[0004] However, some problems still exist in actual use: However, most peanut cleaning equipment currently on the market uses drum-type or soaking and stirring cleaning devices, which mostly use unidirectional stirring. The cleaning force is relatively gentle and it is difficult to effectively remove stubborn stains from the crevices of the peanut surface, resulting in poor cleaning effect and failure to meet cleanliness standards. At the same time, these devices often require manual assistance or use complex spiral conveyor devices in the discharge stage, which not only increases labor intensity and reduces the level of automation, but also easily damages the peanut seed coat during the discharge process, affecting the commercial value. In addition, problems such as water splashing and inconvenience in handling impurities during the cleaning process also restrict the application of existing equipment in modern and large-scale production, making it difficult to meet the needs of efficient and clean batch processing. Summary of the Invention

[0005] The purpose of this invention is to provide a peanut cleaning device and cleaning method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peanut washing device, comprising a washing tank, a sedimentation tank, and a shielding cover, and further comprising: An agitation assembly is located inside a cleaning tank. The agitation assembly includes a connecting rod located inside the cleaning tank. Several agitating filters are fixedly connected to the outer side of the connecting rod in a circular array. Both ends of the connecting rod are fixedly connected to a connecting pipe, and the outer side of the connecting pipe has a through groove in a circular shape. An extension pipe and a discharge pipe are fixedly connected to the ends of the two connecting pipes away from the connecting rod, respectively. The discharge pipe extends to the outer side of the cleaning tank and is movably connected to a bearing seat.

The other end of the extension pipe is movably connected to a feed pipe via a sealed bearing. A reverse cleaning assembly is located inside the cleaning tank and is connected to the agitation assembly via a transmission connection. The discharge control component is movably connected to one side of the cleaning tank and to the outside of the agitation component. The discharge control component includes a mounting bracket sleeved on the outside of the extension tube via a bearing. The mounting bracket is L-shaped and a drive motor is fixedly connected to the surface of the mounting bracket. A support frame is fixedly connected to the bottom of the mounting bracket, and the top of the support frame is movably connected to the outside of the connection between the extension tube and the feed tube via a rotating shaft. Preferably, both sides of the mounting frame are movably connected to an electro-hydraulic rod via a rotating shaft, and the other end of the electro-hydraulic rod is movably connected to one end of the sedimentation tank via a rotating shaft. The sedimentation tank is fixedly connected to the bottom of the cleaning tank. A drain pipe is fixedly connected to one side of the sedimentation tank and is interconnected with the interior of the sedimentation tank. An electric control valve is movably connected inside the drain pipe. Two shields are provided, and a set of symmetrical guide rails are slidably connected to the bottom. One end of each guide rail is fixedly connected to the outside of the cleaning tank, and the shield is arc-shaped. A set of symmetrical electric push rods is fixedly connected to both ends of the cleaning tank, and the other end of each electric push rod is fixedly connected to both ends of the shield.

[0007] Preferably, the agitation assembly further includes two pulleys 1 fixedly connected to the outside of the extension tube, and pulley 2 is provided directly below the two pulleys 1. The pulleys 1 and 2 are connected by a transmission belt. A drive motor is provided on one side of the pulley 2, and the drive motor is fixedly connected to the shaft of the pulley 2 by a coupling.

[0008] Preferably, the reverse cleaning assembly includes a drive gear fixedly connected to the outside of the extension tube, the drive gear meshing with a transmission gear, and a transmission shaft fixedly connected to one side of the transmission gear. A connecting frame is movably connected to the middle position of the transmission shaft via a rotating shaft, and the connecting frame is movably connected to the outside of the extension tube via a rotating shaft.

[0009] Preferably, a second transmission gear is fixedly connected to the other end of the transmission shaft. The second transmission gear meshes with a connecting gear, and the connecting gear is movably connected to one side of the connecting frame via a rotating shaft. The connecting gear meshes with a driving gear, and the driving gear is fixedly connected to the outside of the extension tube. The other end of the driving gear is fixedly connected to a transmission disc via a rotating shaft, and the transmission disc is sleeved on the outside of the connecting tube. A reverse cleaning filter cover is fixedly connected to the outside of the transmission disc, and the reverse cleaning filter cover is cylindrical. The reverse cleaning filter cover is sleeved on the outside of the agitating filter screen. The other end of the reverse cleaning filter cover is fixedly connected to a collecting hopper, which is funnel-shaped, and the inside of the collecting hopper is fixedly connected to the outside of the discharge pipe via a rotating shaft.

[0010] A method for cleaning peanuts includes the following steps: S1. The peanuts to be cleaned are fed into the device through the feed pipe. Under the action of gravity, the material is conveyed to the inside of the reverse cleaning filter cover through the extension pipe, the connecting pipe and the through groove in sequence. Then, the electric push rod is controlled to push the two shields to move towards each other along the guide rail until they completely cover the top of the cleaning tank, forming a cleaning operation space. S2. Start the drive motor to drive pulley two to rotate, and drive pulley one of the two pulleys to rotate synchronously through the transmission belt, so that the extension tube drives the connecting rod to rotate through the connecting tube, and the several agitated filter screens fixed on the connecting rod rotate in the forward direction inside the reverse cleaning filter cover. S3. At the same time, the drive gear on the extension tube drives the gear to rotate in the opposite direction through the transmission gear one, the transmission gear two and the connecting gear in sequence. In turn, the transmission disc drives the reverse cleaning filter to rotate in the opposite direction, thereby forming strong turbulence and shearing in the cleaning liquid, so that the peanut particles are fully rubbed and flushed in the relative motion, achieving efficient cleaning. S4. After the set cleaning time is completed, stop the drive motor, control the electric push rod to pull the shield along the guide rail to open the top of the cleaning tank, and at the same time open the electric control valve of the drain pipe to discharge the cleaning wastewater containing impurities and sludge from the sedimentation tank for centralized sedimentation treatment. S5. Simultaneously start two electric hydraulic rods to smoothly lift the mounting frame. Under the support and guidance of the bearing seat, the entire cleaning mechanism slowly lifts with the connection between the extension pipe and the feed pipe as the fulcrum. As the tilt angle increases, the cleaned peanuts gather at the bottom of the collection hopper under the action of gravity and are finally automatically discharged from the device through the through groove and the discharge pipe. S6. After the material is discharged, control the electric hydraulic rod to slowly retract, so that the cleaning mechanism can smoothly return to a horizontal state and all parts can be reset to their initial positions, preparing for the next cleaning operation.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a drive motor to output stable torque, which is then efficiently transmitted to the extension pipe via a transmission belt and the precise cooperation of pulley one and pulley two. This drives the connecting pipe and connecting rod to rotate synchronously. Several agitating filter screens arranged in a ring on the connecting rod rotate continuously and evenly in the forward direction within the cleaning tank. This not only effectively prevents peanuts from accumulating and creating cleaning dead zones during the cleaning process, but also actively pushes the peanuts to tumble and move in the cleaning liquid through the rotation of the agitating filter screens, ensuring that each peanut can fully contact the cleaning liquid. At the same time, the material is continuously and evenly transported to the inside of the reverse cleaning filter cover through the grooves on the side wall of the feed pipe, extension pipe, and connecting pipe, realizing the synchronous operation of feeding and agitation. Its integrated transmission and conveying design lays a solid and efficient foundation for subsequent deep cleaning. 2. This invention uses a drive gear on an extension tube as the power input end, which sequentially meshes with transmission gear one, transmission shaft, and transmission gear two, ultimately driving the reverse cleaning filter cover fixed on the drive gear. This series of gear transmission mechanisms precisely transmits power in the reverse direction, causing the reverse cleaning filter cover and the internal agitating filter screen to form a pair of high-speed counter-rotating kinematic pairs. When the two rotate relative to each other in the cleaning fluid, turbulence, vortices, and hydraulic shearing effects are generated, forcing the peanut particles to continuously change their posture in the complex flow field, rubbing against each other and being violently washed by the cleaning fluid, thereby efficiently removing surface mud and stubborn stains. While the reverse cleaning filter cover, which is fitted outside the agitating filter screen, rotates, its end hopper can effectively collect the cleaned peanuts, while the filter screen itself plays a preliminary role in screening impurities. This dual-filter screen reverse collaborative working mode greatly improves cleaning efficiency and the purity of impurity separation.

[0012] 3. This invention controls two synchronous electric hydraulic rods to smoothly lift the L-shaped mounting frame. The entire cleaning mechanism rotates around the sealed bearing at the connection between the extension pipe and the feed pipe. Supported and guided by the bearing seat at the other end, it slowly tilts. As the tilt angle increases precisely, the cleaned peanuts naturally slide into the collection hopper at the end of the reverse cleaning filter under gravity. Finally, they are smoothly discharged from the device through the through-slot of the connecting pipe and the discharge pipe, replacing the traditional manual material handling or screw conveyor. This not only avoids secondary damage and cross-contamination of the material, but also achieves a stable and controllable discharge process, significantly improving the overall automation level and operational continuity of the device, and providing a strong guarantee for large-scale production.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1 to 9The present invention provides a technical solution: a peanut washing device, including a washing tank 1, a sedimentation tank 2 and a shield 3, and further including: an agitation component 4, which is located inside the washing tank 1; a reverse cleaning component 5, which is located inside the washing tank 1 and is convexly connected to the agitation component 4; and a discharge control component 6, which is movably connected to one end of the outer side of the washing tank 1 and is movably connected to the outer side of the agitation component 4.

[0017] Please see Figure 1 and Figure 2 The sedimentation tank 2 is fixedly connected to the bottom of the cleaning tank 1. A drain pipe 7 is fixedly connected to one side of the sedimentation tank 2 and is connected to the interior of the sedimentation tank 2. An electric control valve is movably connected inside the drain pipe 7. There are two shields 3 and a set of symmetrical guide rails 10 are slidably connected to the bottom. One end of each guide rail 10 is fixedly connected to the outside of the cleaning tank 1. The shields 3 are arc-shaped. A set of symmetrical electric push rods 8 are fixedly connected to both ends of the cleaning tank 1, and the other end of each electric push rod 8 is fixedly connected to both ends of the shields 3.

[0018] The sedimentation tank 2 is fixedly connected to the bottom of the cleaning tank 1. Its function is to contain the wastewater containing a large amount of mud and impurities discharged from the cleaning tank 1 after the cleaning operation is completed. The solid pollutants are collected at the bottom of the tank by gravity sedimentation, realizing the preliminary treatment of solid-liquid separation. The sewage pipe 7 fixedly connected to one side and the internal electric control valve can be used to control the timed discharge of the settled sewage, which is convenient for centralized treatment and effectively avoids secondary pollution of impurities. At the same time, two arc-shaped shields 3 are slidably connected to the outside of the cleaning tank 1 through the bottom guide rail 10 and are driven by the electric push rods 8 at both ends to move in opposite directions. Their function is to close at the beginning of the cleaning to cover the top of the cleaning tank 1, effectively preventing liquid splashing and external dust from entering during the cleaning process, ensuring the cleanliness and safety of the working environment. After the cleaning is completed, they can be automatically opened to facilitate the subsequent material discharge and sewage discharge operations.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The agitation assembly 4 includes a connecting rod 401 located inside the cleaning tank 1. Several agitating filters 402 are fixedly connected to the outer side of the connecting rod 401 in a circular array. Both ends of the connecting rod 401 are fixedly connected to a connecting pipe 403, and the outer side of the connecting pipe 403 is provided with a through groove 404 in a circular shape. The ends of the two connecting pipes 403 away from the connecting rod 401 are respectively fixedly connected to an extension pipe 405 and a discharge pipe 406. The discharge pipe 406 extends to the outer side of the cleaning tank 1 and is movably connected to a bearing seat 407. The bottom of the bearing seat 407 is open to the outside of the tank. The extension tube 405 is movably connected to one end of the sedimentation tank 2 via a rotating shaft, and the other end of the extension tube 405 is movably connected to the feed tube 9 via a sealed bearing. The stirring assembly 4 also includes two pulleys 408 fixedly connected to the outside of the extension tube 405. A pulley 409 is provided directly below the two pulleys 408, and the pulleys 408 and 409 are connected by a transmission belt 410. A drive motor 411 is provided on one side of the pulley 409, and the drive motor 411 is fixedly connected to the shaft of the pulley 409 via a coupling.

[0020] The drive motor 411 drives the pulley 409, which transmits power to the two pulleys 408 on the extension pipe 405 via the transmission belt 410. This causes the extension pipe 405, the connecting pipe 403, and the connecting rod 401 to rotate synchronously. Several agitating filters 402 fixed to the outside of the connecting rod 401 rotate forward in the cleaning tank 1, continuously tumbling and agitating the peanuts. The through groove 404 on the outside of the connecting pipe 403 serves as a material channel, allowing the peanuts fed into the feed pipe 9 to be conveyed to the cleaning area through the extension pipe 405 and the connecting pipe 403 in sequence. The entire assembly achieves dynamic sealing at the feed end through the sealed bearing connection between the extension pipe 405 and the feed pipe 9. The cooperation between the discharge pipe 406 and the bearing seat 407 provides rotational support and guidance for subsequent tilting discharge. Its integrated transmission, agitation, and conveying design provides a stable basic power for efficient cleaning.

[0021] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8The reverse cleaning assembly 5 includes a drive gear 501 fixedly connected to the outside of the extension tube 405. The drive gear 501 meshes with a transmission gear 502, and a transmission shaft 503 is fixedly connected to one side of the transmission gear 502. A connecting frame 504 is movably connected to the middle of the transmission shaft 503 via a rotating shaft, and the connecting frame 504 is movably connected to the outside of the extension tube 405 via a rotating shaft. A second transmission gear 505 is fixedly connected to the other end of the transmission shaft 503. The second transmission gear 505 meshes with a connecting gear 510, and the connecting gear 510 is movably connected to one side of the connecting frame 504 via a rotating shaft. A drive gear 506 is fixedly connected to the outside of the extension tube 405. The other end of the drive gear 506 is fixedly connected to a transmission disc 507 via a rotating shaft. The transmission disc 507 is sleeved on the outside of the connecting tube 403. A reverse cleaning filter cover 508 is fixedly connected to the outside of the transmission disc 507. The reverse cleaning filter cover 508 is cylindrical and is sleeved on the outside of the agitating filter screen 402. A collection hopper 509 is fixedly connected to the other end of the reverse cleaning filter cover 508. The collection hopper 509 is funnel-shaped, and the inside of the collection hopper 509 is fixedly connected to the outside of the discharge tube 406 via a rotating shaft.

[0022] The power input is provided by the drive gear 501 fixed on the extension tube 405. The power is transmitted to the drive gear 506 through a multi-stage gear transmission consisting of transmission gear 1 502, transmission shaft 503 and transmission gear 2 505. This drives the transmission disc 507 and the reverse cleaning filter cover 508 fixed on it to rotate in the opposite direction to the agitation filter screen 402. The reverse rotation generates strong turbulence and shear force in the cleaning liquid, which makes the peanut particles fully rubbed and washed in the relative motion, significantly improving the cleaning effect. The reverse cleaning filter cover 508, which is sleeved on the outside of the agitation filter screen 402, also plays the role of screening impurities while rotating. The funnel-shaped collection hopper 509 at its end is responsible for efficiently collecting peanuts after cleaning, preparing for the subsequent automatic discharge process. The entire assembly is movably connected to the extension tube 405 through the connecting frame 504, ensuring the stability and reliability of the transmission structure.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The discharge control component 6 includes a mounting bracket 601 that is sleeved on the outside of the extension tube 405 via a bearing. The mounting bracket 601 is L-shaped, and the drive motor 411 is fixedly connected to the surface of the mounting bracket 601. A support bracket 602 is fixedly connected to the bottom of the mounting bracket 601, and the top of the support bracket 602 is movably connected to the outside of the connection between the extension tube 405 and the feed tube 9 via a rotating shaft. Both sides of the mounting bracket 601 are movably connected to an electric hydraulic rod 603 via a rotating shaft, and the other end of the electric hydraulic rod 603 is movably connected to one end of the sedimentation tank 2 via a rotating shaft.

[0024] The lifting power is provided by the electric hydraulic rods 603 on both sides of the mounting frame 601, which drives the entire stirring and cleaning structure to tilt. This allows for precise control of the electric hydraulic rods 603, enabling the cleaning mechanism to be slowly and smoothly raised to a predetermined angle. Gravity then allows the cleaned peanuts to be automatically collected and discharged. The entire process requires no manual intervention, achieving a high degree of automation and controllability in the discharge process.

[0025] Working principle: Peanuts to be cleaned are fed into the device through the feed pipe 9. Under the action of gravity, the material is conveyed sequentially through the extension pipe 405, the connecting pipe 403, and the through channel 404 to the inside of the reverse cleaning filter cover 508. Then, the electric push rod 8 is controlled to push the two shields 3 to move towards each other along the guide rail 10 until they completely cover the top of the cleaning tank 1, forming a cleaning working space. The drive motor 411 is started to drive the pulley 2 409 to rotate, which synchronously drives the two pulleys 1 408 through the transmission belt 410. This causes the extension pipe 405 to drive the connecting rod 401 to rotate through the connecting pipe 403. Several agitating filter screens 402 fixed on the connecting rod 401 rotate in the forward direction inside the reverse cleaning filter cover 508. At the same time, the drive gear 501 on the extension pipe 405 drives the gear 506 to rotate in the reverse direction through the transmission gear 1 502, the transmission gear 2 505, and the connecting gear 510. This, in turn, drives the reverse cleaning filter cover 508 to rotate in the reverse direction through the transmission disc 507, thereby stimulating the cleaning fluid. The strong turbulence and shearing action create sufficient friction and scouring of the peanut particles during relative motion, achieving efficient cleaning. After the set cleaning time is completed, the drive motor 411 is stopped, and the electric push rod 8 is controlled to pull the shield 3 along the guide rail 10 to open the top of the cleaning tank 1. At the same time, the electric control valve of the drain pipe 7 is opened to discharge the cleaning wastewater containing impurities and sludge from the sedimentation tank 2 for centralized sedimentation treatment. Simultaneously, the two electric hydraulic rods 603 are started to smoothly lift the mounting frame 601. Under the support and guidance of the bearing seat 407, the entire cleaning mechanism is slowly lifted with the connection between the extension pipe 405 and the feed pipe 9 as the fulcrum. As the tilt angle increases, the cleaned peanuts gather at the bottom of the collection hopper 509 under the action of gravity and are finally automatically discharged from the device through the through channel 404 and the discharge pipe 406. After the discharge is completed, the electric hydraulic rods 603 are controlled to slowly retract, so that the cleaning mechanism smoothly returns to the horizontal state and all components are reset to the initial position, ready for the next cleaning operation.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Start the drive motor (411) to drive the pulley two (409) to rotate, and drive the two pulleys one (408) synchronously through the transmission belt (410), so that the extension tube (405) drives the connecting rod (401) to rotate through the connecting tube (403), and the several agitated filter screens (402) fixed on the connecting rod (401) rotate in the forward direction inside the reverse cleaning filter cover (508); S3. At the same time, the drive gear (501) on the extension tube (405) drives the gear (506) to rotate in the opposite direction through the transmission gear one (502), the transmission shaft (503), the transmission gear two (505) and the connecting gear (510), and then drives the reverse cleaning filter cover (508) to rotate in the opposite direction through the transmission disc (507), thereby forming strong turbulence and shearing in the cleaning liquid, so that the peanut particles are fully rubbed and flushed in relative motion, achieving efficient cleaning. S4. After the set cleaning time is completed, stop the drive motor (411), control the electric push rod (8) to pull the shield (3) along the guide rail (10) to open the top of the cleaning tank (1), and at the same time open the electric control valve of the drain pipe (7) to discharge the cleaning wastewater containing impurities and sludge from the sedimentation tank (2) for centralized sedimentation treatment. S5. Simultaneously start two electric hydraulic rods (603) to smoothly lift the mounting frame (601). Under the support and guidance of the bearing seat (407), the entire cleaning mechanism is slowly lifted with the connection between the extension pipe (405) and the feed pipe (9) as the fulcrum. As the tilt angle increases, the cleaned peanuts gather at the bottom of the collection hopper (509) under the action of gravity, and are finally automatically discharged from the device through the through groove (404) and the discharge pipe (406). S6. After the material is discharged, control the electric hydraulic rod (603) to slowly retract, so that the cleaning mechanism can be smoothly restored to a horizontal state and all parts can be reset to their initial positions to prepare for the next cleaning operation.
