Description

Technical Field

[0001] This invention relates to the field of fruit processing equipment technology, specifically to a fruit processing cleaning device with a sorting mechanism. Background Technology

[0002] In the deep processing of fruit, washing and sorting are two crucial pretreatment steps. Washing removes mud, pesticide residues, and microorganisms from the surface of the fruit, while sorting grades the fruit according to its diameter to meet the processing requirements of different products.

[0003] Currently, the existing equipment has the following main shortcomings: First, washing and sorting are usually done in separate steps using independent equipment. The fruit is first processed by a bubble washing machine or a spray washing machine, and then conveyed to a separate drum screen or vibrating grading screen for sorting. These two sets of equipment not only occupy a lot of space and consume a lot of energy, but also require the material to be transferred between the equipment, increasing the risk of fruit damage and labor costs.

[0004] Secondly, most existing sorting equipment is of a rigid structure. Rotary drum screens and vibrating screens use rigid metal or plastic mesh. During the sorting process, the fruit vibrates or tumbles with the screen, resulting in numerous hard collisions with the mesh and the equipment casing. Simultaneously, the fruit falling from a height onto the screen surface also generates gravitational impact. These collisions easily lead to damage to the peel and bruising of the flesh, which is particularly detrimental to thin-skinned, juicy fruits such as strawberries, cherries, and table grapes, directly affecting product quality and commercial value.

[0005] Therefore, developing a fruit processing device that integrates washing and sorting without hard collisions during the sorting process has significant practical value. In view of this, in-depth research was conducted to address the above-mentioned issues, leading to this case. Summary of the Invention

[0006] The purpose of this invention is to provide a fruit processing cleaning device with a sorting mechanism, which aims to solve the technical problems in the prior art where the cleaning and sorting equipment are independent of each other and the hard collision during the sorting process causes serious fruit damage.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fruit processing cleaning device with a sorting mechanism, comprising: A cleaning tank assembly, the cleaning tank assembly including at least a first cleaning zone and a second cleaning zone; A flexible sorting mesh has a drag net section and a screening section. The starting end of the flexible sorting mesh is the drag net section, which is movably disposed between the first cleaning zone and the second cleaning zone and flips up and down. A driving mechanism is connected to the flexible sorting mesh surface and is used to drive the flexible sorting mesh surface to move from the first cleaning zone to the second cleaning zone after it is flipped over. The trawl section initially hangs down in the first washing area to receive fruit from the first washing area; when the trawl section flips upward, it scoops up the fruit and transfers it to the screening section; the screening section, under the action of the driving mechanism, drags the fruit above the second washing area, and during the movement, the fruit flips and rolls along the surface of the screening section to fall into different screening areas.

[0008] Preferably, the flexible sorting mesh surface has multiple screening zones along its length, and the mesh size of each screening zone increases sequentially along the moving direction of the flexible sorting mesh surface to sort fruits of different sizes. The number of screening zones is preferably three to five, corresponding to small, medium, large, and extra-large fruits, respectively; the length of each screening zone is set according to the average passing time of the fruit to ensure that the fruit has sufficient time to fall and be screened when it reaches the corresponding mesh area.

[0009] Preferably, a movable brushing assembly is provided above the second cleaning zone. The movable brushing assembly includes a spray pipe and a brush roller. The movable brushing assembly is linked to the driving mechanism and synchronously brushes and sprays the fruit located on the screening section as the flexible sorting mesh moves. Multiple spray holes are evenly distributed on the spray pipe, with the spray direction facing the upper surface of the flexible sorting mesh. The surface of the brush roller is made of food-grade soft bristles, ensuring that the bristle tips only contact the fruit surface without penetrating the pulp during brushing, thus achieving gentle brushing.

[0010] Preferably, the driving mechanism includes a drive motor, drive wheels, and a movable frame, wherein the movable frame is driven by the drive motor and drive wheels to move above the second cleaning zone; The movable brush washing assembly is mounted on the movable frame, allowing the brush roller to move synchronously with the moving direction of the flexible sorting mesh. The drive motor is a servo motor equipped with a reducer to achieve speed adjustment, adapting to the washing and screening needs of different types of fruits. The movable frame is also equipped with guide wheels that slide in cooperation with guide rails set on the side wall of the second washing area to prevent the movable frame from swaying during movement.

[0011] Preferably, the trawl segment is hinged to the side wall of the movable frame via a flipping mechanism. The flipping mechanism includes a flipping frame and a hydraulic drive rod. The trawl segment is connected to the flipping frame and is driven by the hydraulic drive rod to form an up-and-down deflection structure on the side wall of the movable frame. The extension and retraction stroke of the hydraulic drive rod matches the flipping angle of the trawl segment. When the hydraulic drive rod retracts from fully extended to fully retracted, the trawl segment flips upward from a hanging state to a state above horizontal, ensuring that the collected fruit can smoothly slide to the screening section.

[0012] Preferably, the connection between the flipping frame and the flexible sorting mesh further includes a tension adjustment component. The main body of the tension adjustment component is an elastic winding drum, used to adjust the tension of the flexible mesh. The elastic winding drum is equipped with a spiral spring, which can apply tension to the flexible sorting mesh. When the weight of the fruit on the flexible sorting mesh changes, the elastic winding drum automatically retracts or expands the mesh length, ensuring the mesh always maintains a moderate tension. This facilitates rinsing and washing with the close-fitting washing components while preventing fruit accumulation or inaccurate sorting due to an excessively loose mesh.

[0013] Preferably, the first cleaning zone is a bubble cleaning zone, with a bubble generating device at its bottom; the second cleaning zone is a clean water rinsing zone, with an overflow outlet and a water supply pipe inside. The bubble generating device forms a uniform bubble curtain to gently rinse the surface of the fruit; the overflow outlet is located on the upper side wall of the second cleaning zone, and the water supply pipe is connected to a clean water source to maintain a constant water level.

[0014] Preferably, the flexible sorting mesh is made of food-grade silicone mesh or polyester fiber mesh, and the edges of the flexible sorting mesh are provided with flexible reinforcing edging to help form an arc-shaped scoop for catching the fruit. Silicone mesh has good elasticity and anti-slip properties, which can further buffer the contact force between the fruit and the mesh surface; when polyester fiber mesh is used, its surface is coated with a food-grade waterproof coating, and the edges of the mesh are rounded; flexible memory alloy wires or high-elasticity rubber strips are embedded in the edging, so that the trawl segment can naturally form an arc-shaped scoop when flipping to catch the fruit, effectively preventing the fruit from rolling off the edges of the mesh.

[0015] Preferably, a partition is provided between the first cleaning zone and the second cleaning zone, and the flexible sorting mesh extends from the first cleaning zone to the second cleaning zone, bypassing the top of the partition. The second washing zone is equipped with partitions corresponding to the screening zones at each stage, dividing the second washing zone into multiple independent rinsing sections. Each rinsing section has an inclined discharge conveyor belt at its side. The partitions completely separate the rinsing sections within the first and second washing zones, improving the washing effect while preventing mixing of fruits of different sizes during the rinsing process. The inclined discharge conveyor belt is equipped with baffles to smoothly lift the rinsed fruit from the water to the discharge port.

[0016] Preferably, the cleaning device further includes a control system, which is electrically connected to the drive mechanism, the flipping mechanism, and the movable brush washing assembly, respectively, for controlling the moving and sorting speed of the flexible sorting mesh to match the cleaning and discharging speed of the equipment. The control system includes a programmable logic controller and a human-machine interface touchscreen. After the operator sets parameters such as processing output via the touchscreen, the control system automatically calculates and matches the drive speed of the drive mechanism, the flipping speed of the flipping mechanism, and the spray pressure and brush roller speed of the movable brush washing assembly. The control system also includes multiple sensors for real-time monitoring of the fruit distribution and processing status.

[0017] Compared with existing technologies, this fruit processing cleaning device with a sorting mechanism has the following advantages: 1. Flexible processing throughout the entire process significantly reduces fruit damage. This invention uses a flexible sorting mesh that simultaneously performs both conveying and screening functions. The fruit is in contact with the flexible mesh throughout the entire process, replacing the traditional rigid screen structure and avoiding hard collisions during screening. At the same time, the screened fruit falls directly into the clean water in the second washing zone, where the water buffer completely offsets the impact of gravity. From picking, conveying, screening to unloading, the entire process eliminates the risk of rigid collisions, significantly reducing the rate of fruit skin damage and pulp bruising, making it especially suitable for processing delicate berries.

[0018] 2. Integrated washing and sorting system reduces equipment costs and floor space. This invention integrates multiple processes such as bubble washing, spray washing, grading and screening, and rinsing with clean water into a single device. A flexible meshing mechanism completes the entire process of fruit transportation and processing, eliminating the need for intermediate lifting and transfer mechanisms required by traditional separate equipment. This not only reduces secondary damage during transportation but also significantly reduces the overall floor space required by the equipment, lowering equipment procurement and maintenance costs.

[0019] 3. Synchronized and coordinated brushing improves cleaning uniformity and cleanliness. The movable brushing component and drive mechanism of this invention are linked and can move synchronously with the flexible sorting mesh. In conjunction with the rolling and turning of the fruit on the mesh, it can achieve all-round dynamic brushing and spray rinsing of the fruit surface. Compared with a fixed spray brushing structure, there are no dead corners in the cleaning, the cleanliness is higher, and the fruit skin will not be scratched due to relative movement.

[0020] 4. Graded rinsing and zoned discharge ensure smooth and efficient process flow. The second washing zone of this invention is divided into independent rinsing zones corresponding to each grade of screening zone by partitions. Fruits of different sizes after screening fall directly into their corresponding zones to complete the final rinsing, and are then discharged in their respective zones via their respective discharge conveyors. Grading and rinsing are completed simultaneously, resulting in a compact process flow, high processing efficiency, and prevention of mixing of fruits of different sizes again.

[0021] 5. High structural adaptability and high degree of automation. The flexible sorting mesh of this invention is made of food-grade flexible material, which is suitable for the processing needs of various types of fruits. With the tension adjustment component, the mesh tension can be flexibly adjusted to ensure the screening effect. At the same time, the control system realizes the coordinated linkage of the drive, flipping and washing mechanisms. The operating parameters can be adjusted according to the fruit type and processing needs, with a high degree of automation and convenient operation. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-10 The present invention provides the following technical solutions: like Figures 1-4 As shown, the fruit processing cleaning device with a sorting mechanism mainly includes: a cleaning tank assembly, a flexible sorting mesh 3, a drive mechanism 4, a movable brushing assembly 5, a flipping mechanism 6, a tension adjustment assembly 7, and a control system 9.

[0026] The cleaning tank assembly includes at least a first cleaning zone 1 and a second cleaning zone 2. The first cleaning zone 1 is a bubble cleaning zone, with a bubble generator 11 installed at its bottom; the second cleaning zone 2 is a clean water rinsing zone, with an overflow outlet and a water supply pipe installed inside. A partition 8 is installed between the first cleaning zone 1 and the second cleaning zone 2, and a flexible sorting mesh 3 extends from the first cleaning zone 1 to the second cleaning zone 2, bypassing the top of the partition 8.

[0027] The flexible sorting mesh 3 has a drag net section 31 and a screening section 32, with the drag net section 31 being the starting end of the flexible sorting mesh 3. The drag net section 31 is movably positioned between the first washing zone 1 and the second washing zone 2, allowing it to be flipped up and down. The flexible sorting mesh 3 is made of food-grade silicone mesh or polyester fiber mesh, and its edges are reinforced with flexible edging to help form an arc-shaped scoop for catching fruit.

[0028] The drive mechanism 4 is connected to the flexible sorting screen 3 and is used to drive the flexible sorting screen 3 to move from the first cleaning zone 1 to the second cleaning zone 2. The drive mechanism 4 includes a drive motor 41, a drive wheel 42, and a movable frame 43. The movable frame 43 is driven by the drive motor 41 and the drive wheel 42 to move above the second cleaning zone 2.

[0029] A movable brush washing assembly 5 is installed above the second cleaning zone 2. The movable brush washing assembly 5 includes a spray pipe 51 and a brush roller 52. The movable brush washing assembly 5 is installed on the movable frame 43, so that the brush roller 52 moves synchronously with the moving direction of the flexible sorting mesh surface 3 to achieve linkage brush washing.

[0030] The trawl segment 31 is hinged to the side wall of the movable frame 43 via a flipping mechanism 6. The flipping mechanism 6 includes a flipping frame 61 and a hydraulic drive rod 62. The trawl segment 31 is connected to the flipping frame 61 and is driven by the hydraulic drive rod 62 to form an up-and-down deflection structure on the side wall of the movable frame 43. The connection between the flipping frame 61 and the flexible sorting mesh surface 3 also includes a tension adjustment component 7. The main body of the tension adjustment component 7 is an elastic winding drum, used to adjust the tension of the flexible mesh surface.

[0031] like Figures 9-10 As shown, the second washing zone 2 is equipped with partitions 8 corresponding to each screening zone, dividing the second washing zone 2 into multiple independent rinsing zones. Each rinsing zone has an inclined discharge conveyor belt on its side.

[0032] The cleaning device also includes a control system 9, which is electrically connected to the drive mechanism 4, the flipping mechanism 6 and the movable brush washing assembly 5, respectively, and is used to control the moving sorting speed of the flexible sorting screen 3 to match the cleaning and discharge speed of the equipment.

[0033] The working process of the fruit processing cleaning device with a sorting mechanism will be described in detail below, based on the above structure.

[0034] Step 1: First Cleaning Zone 1 - Initial Bubble Wash like Figures 1-4 As shown, the fruit to be processed first enters the first cleaning zone 1. The first cleaning zone 1 is a bubble cleaning zone, where the bubble generator 11 at the bottom produces a uniform bubble curtain to gently wash the surface of the fruit, removing mud and surface deposits. During this process, the drag net section 31 of the flexible sorting net surface 3 initially hangs down in the first cleaning zone 1.

[0035] The fruit moves slowly in the first washing zone 1 under the action of water flow and air bubbles, gradually approaching the position of the trawl section 31 of the flexible sorting net surface 3.

[0036] Step 2: Flip the trawling net segment 31 to collect the fruit. like Figures 5-8 As shown, when the fruit moves to the position of the trawl segment 31, the control system 9 sends a command to the flipping mechanism 6. The hydraulic drive rod 62 starts to move, driving the flipping frame 61 to flip upward. At this time, the trawl segment 31 gradually rises from its initial drooping state.

[0037] During the flipping process of the trawl section 31, the elastic winding drum of the tension adjustment component 7 automatically adjusts the tension of the flexible sorting mesh surface 3. At the same time, the flexible reinforced edge helps to form an arc-shaped scoop, scooping up the fruit in the first washing zone 1. When the hydraulic drive rod 62 retracts from the fully extended state to the fully retracted state, the trawl section 31 completes the upward flipping, transferring the fruit to the screening section 32.

[0038] Step 3: Flexible mesh surface dragged and moved while simultaneously brushing After the fruit is collected, the drive motor 41 of the drive mechanism 4 starts working. The drive motor 41 drives the movable frame 43 to move towards the second washing zone 2 via the drive wheel 42. Since the flexible sorting mesh 3 is connected to the movable frame 43, the mesh is dragged along, causing the fruit on the screening section 32 to move towards the second washing zone 2.

[0039] During this process, the fruit detaches from the water surface of the first washing zone 1 and the second washing zone 2 and is placed on the screening section 32 of the flexible sorting mesh surface 3. The movable brush washing assembly 5 is installed on the movable frame 43 and moves synchronously with the movable frame 43. The spray pipe 51 sprays clean water onto the surface of the fruit, while the brush roller 52 gently brushes the surface of the fruit. Because the fruit will naturally tumble and roll when dragged on the mesh surface, the brush roller 52 can evenly brush all surfaces of the fruit, without any dead corners.

[0040] It is worth noting that even if the total amount of fruit collected is different during the brushing process, or if some fruit has been sieved and fallen, causing a change in the total amount, the brush roller 52 can still maintain contact with the fruit for brushing under the action of the tension adjustment component 7. At the same time, the sprayed water can wash away the mud and sand attached to the fruit surface in time.

[0041] Step 4: Grading and screening during the drag-and-drop process The flexible sorting mesh 3 has multiple screening sections 321 along its length. The mesh size of each screening section 321 increases sequentially along the moving direction of the flexible sorting mesh 3, corresponding to small fruit, medium fruit, large fruit and extra-large fruit grades respectively.

[0042] During the continuous dragging process of the drive mechanism 4, the fruit moves with the mesh surface and continuously flips and rolls. When it moves to the screening section 321 corresponding to its own size, the fruit falls through the mesh, completing the grading and screening.

[0043] For example, smaller fruits fall first in the first screening section 321 (with the smallest mesh size), medium-sized fruits fall in the second screening section 321, and large and extra-large fruits fall in subsequent screening sections 321. Throughout the screening process, the fruits only come into contact with the flexible mesh surface and fall into the water in the second washing zone 2, without any rigid collisions. The screening power comes from the dragging motion itself, and the fruits fall and are screened while being rolled and washed, eliminating the need for an additional vibration mechanism.

[0044] Step 5: Rinse thoroughly with clean water, then perform a final wash in designated areas. The second washing zone 2 is equipped with partitions 8 corresponding to the various screening sections 321, dividing the second washing zone 2 into multiple independent rinsing sections. Fruits of different sizes fall directly into their respective rinsing sections after falling from their corresponding screening sections 321.

[0045] In the rinsing section, the fruit is immersed in clean water for a final rinse. A water supply pipe continuously replenishes water to the second washing zone (2), while an overflow outlet drains water to maintain a constant water level and cleanliness. The process of the fruit falling into the water is completely cushioned by the water's cushioning, eliminating the impact of gravity and preventing any hard collisions.

[0046] Step 6: Sectional discharge Each rinsing section is equipped with an inclined discharge conveyor belt at its side. The surface of the discharge conveyor belt is fitted with baffles to smoothly lift the rinsed fruit from the water to the discharge port. The conveyor belt outputs fruits of different sizes separately, completing the entire washing, screening, and discharge process.

[0047] During this process, the conveying of the discharge conveyor belt is matched with the movement of the flexible sorting mesh 3 to ensure smooth process connection.

[0048] Operating parameters and adjustment methods of each component As a preferred embodiment, the following parameters can be adjusted according to the type of fruit and processing requirements in practical applications: The drive motor 41 is a servo motor equipped with a reducer, and the drive speed is controlled between 0.05-0.2 m / s. For delicate fruits such as strawberries and cherries, a lower speed is selected; for harder fruits such as apples and oranges, the speed can be appropriately increased.

[0049] The surface of the brush roller 52 is made of food-grade soft bristles. The rotation speed of the brush roller 52 can be adjusted by the control system 9, and the tension adjustment component 7 maintains contact so that the bristle tips only contact the surface of the fruit without penetrating the pulp, thus achieving gentle brushing.

[0050] The flexible winding drum contains a spiral spring that applies tension to the flexible sorting mesh 3. When the weight of the fruit on the flexible sorting mesh 3 changes, the flexible winding drum automatically retracts or expands the mesh length, ensuring the mesh remains under appropriate tension. A manual adjustment knob is located at the end of the flexible winding drum for easy setting of the initial tension during equipment debugging.

[0051] Multiple spray holes are evenly distributed on the spray pipe 51, with the spray direction facing the upper surface of the flexible sorting mesh 3. The spray water pressure is controlled between 0.2-0.5 MPa, which can wash away dirt on the fruit surface without damaging the peel.

[0052] The control system 9 includes a programmable logic controller and a human-machine interface touch screen. After the operator sets parameters such as fruit type and processing output through the touch screen, the control system 9 automatically calculates and matches the drive speed of the drive mechanism 4, the flipping speed of the flipping mechanism 6, and the spray pressure and rotation speed of the movable brush washing component 5 and the brush roller 52.

[0053] The control system 9 also includes multiple sensors, respectively installed at the discharge end of the first cleaning zone 1, each screening section 321 of the flexible sorting mesh 3, and the discharge end of the second cleaning zone 2, for real-time monitoring of the fruit distribution and processing status. When an abnormality is detected (such as fruit accumulation, mesh misalignment, etc.), an alarm is automatically triggered or the machine is shut down. The control system 9 is also electrically connected to the bubble generator 11, automatically adjusting the bubble intensity according to the fruit load to achieve energy-saving operation.

[0054] It should be understood that the above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0055] For example, the material of the flexible sorting mesh 3 can be selected according to the type of fruit being processed. When processing fruits with extremely delicate skin, such as strawberries and cherries, food-grade silicone mesh (Shore hardness 30-50A, mesh thickness 2-5mm) is preferred, utilizing the elasticity of silicone to further buffer the contact force between the fruit and the mesh. When processing fruits with harder skin, such as apples and pears, polyester fiber mesh (coated with a food-grade waterproof coating, with rounded edges on the mesh holes) can be used to reduce costs and extend service life.

[0056] For example, the number of screening zones 321 can be set to three to five, corresponding to small, medium, large, and extra-large fruit grades, respectively. For processing scenarios with coarser grading requirements, three screening zones 321 can be used; for high-standard grading scenarios, five screening zones 321 can be used.

[0057] For example, in addition to the hydraulic drive rod 62, the flipping mechanism 6 can also be driven by an electric push rod or a cylinder, which can also achieve the up-and-down flipping function of the trawl section 31.

[0058] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.

[0059] In summary, the working principle of this fruit processing cleaning device with a sorting mechanism can be briefly described as follows: the fruit is first pre-washed with air bubbles in the first cleaning zone 1; then, the trolley section 31 flips upward to scoop up the fruit and transfer it to the screening section 32; the drive mechanism 4 drags the flexible sorting screen 3 towards the second cleaning zone 2, and during the movement, the movable brush washing component 5 simultaneously sprays and brushes the fruit; the fruit rolls and flips along the surface of the screening section 32 during the dragging process, and falls from the screening sections 321 with different mesh sizes according to its own size; the fallen fruit enters the corresponding rinsing section in the second cleaning zone 2 for final rinsing with clean water; finally, the fruit is discharged by the discharge conveyor belt at the side of each rinsing section. Throughout the entire process, the fruit only comes into contact with the flexible screen and water, completely avoiding collisions with rigid structures.

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 variations 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.
