Description

Technical Field

[0001] This invention relates to the field of fruit processing technology, specifically to a conveying and cleaning machine for fruit processing. Background Technology

[0002] Conveyor washing machines are crucial equipment in the fruit processing industry. They are designed to improve production efficiency and ensure the hygiene and safety of fruits. These machines are typically integrated into fruit processing production lines as a pre-treatment step. Bubble washing machines are widely used cleaning equipment in the fruit processing field. Their core advantages lie in their efficient, environmentally friendly, and automated cleaning capabilities. They are suitable for cleaning a variety of fruits and can perform efficient and comprehensive cleaning.

[0003] Existing bubble washing machines have some drawbacks. Traditional bubble washing machines typically only have limited water pressure adjustment capabilities, making it difficult to find a suitable water pressure balance point when washing both soft and hard fruits simultaneously. Soft fruits, such as grapes, are extremely sensitive to water pressure due to their thin skin and tender flesh; excessive water pressure can easily cause them to crack and damage their skin, affecting the integrity and quality of the fruit. Hard fruits, such as apples, have thick skin and require higher water pressure to effectively remove surface dirt and pesticide residues. Therefore, existing equipment often struggles to balance cleaning effectiveness and fruit integrity when processing both types of fruit at the same time. In addition, traditional bubble washing machines easily create cleaning dead zones when washing fruits with special shapes, such as pears and peaches, which have concave or convex bottoms. Although the equipment is designed with bubble agitation and stirring devices, these devices often cannot ensure that the fruit is evenly rotated in the water when dealing with larger and heavier fruits. As a result, dirt and pesticide residues on the bottom of the fruit, which are in the cleaning dead zones for a long time, are difficult to remove effectively. Summary of the Invention

[0011] Furthermore, a waterproof spring rod is provided at the connection between the lower feed pipe and the lower cleaning pipe, the two sides of the lower feed pipe are fixedly connected to the inner side surface of the cleaning tank, and multiple bottom arc-shaped brackets are provided on the bottom surface of the lower cleaning pipe.

[0012] Furthermore, the water flow transmission belt is equipped with a control motor for driving it, and the water flow transmission belt is also equipped with multiple internal support rods for support. The inner side surface of the cleaning tank is also equipped with multiple fixed support plates, and a waterproof spring rod is also provided above the fixed support plate. The top end of the waterproof spring rod is connected to the bottom surface of the cleaning pipe below.

[0013] Furthermore, the cleaning mechanism also includes a discharge assembly, which includes a draining conveyor belt located at the junction of the cleaning tank and the discharge conveyor belt. A baffle plate is also provided on one side surface of the cleaning tank. Multiple mounting base plates are provided on the surface of the draining conveyor belt. A limiting base plate is fixedly installed on one side surface of the mounting base plate. A rotatable support frame is also provided on one side surface of the mounting base plate. A rotating shaft is provided at the connection between the support frame and the mounting base plate. A draining mesh for draining water is provided on the bottom surface of the support frame.

[0014] Furthermore, the cleaning tank is equipped with multiple rotating shafts. Each fixed horizontal plate is connected to the cleaning pipe below with a rotating shaft. Each end of the rotating shaft is equipped with a sliding disc. A rotating shaft is connected between the rotating shaft and the sliding disc. A force-bearing plate is provided on one side surface of the rotating shaft. A groove for absorbing the impact force of water flow is provided on one side surface of the force-bearing plate. An end weight block is provided on one side surface of the force-bearing plate.

[0015] Furthermore, a connecting block is provided on one side surface of the rotating shaft, and arc grooves that mate with both sides of the connecting block are provided on the bottom surface of the lifting rod and the upper surface of the branch top pile. Arc grooves that mate with the connecting block are provided on the top surfaces of the two protrusions on the upper surface of the branch top pile.

[0016] Furthermore, the inner side surface of the cleaning tank is provided with a water level indicator, the upper surface of the cleaning tank is provided with multiple spray nozzles, the primary surface of each spray nozzle is provided with a water supply pipe for supplying water, the bottom of both the feeding conveyor belt and the discharging conveyor belt is provided with a support frame, and the upper surface of the discharging conveyor belt is provided with a blower.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this solution, a separate washing component is installed. The water flow propels the lower washing pipe to vibrate, causing the soft fruits inside to move up and down. This enhances the washing effect while avoiding the direct impact of excessive water flow. In addition, the cooperation between the lower washing pipe and the shower head ensures that soft and hard fruits receive appropriate washing force, protecting the integrity of soft fruits and ensuring the washing quality of hard fruits, thus significantly improving washing efficiency and fruit quality.

[0019] 2. In this solution, by setting up a feeding component, different types of fruits are effectively separated through a movable plate and a fruit separation comb. The movable plate is raised by the drive of an electric telescopic rod, which drives the fruit separation comb to move, thereby separating the smaller soft fruits from the larger hard fruits. This reduces the quality decline and loss caused by mixed washing of fruits and improves the overall efficiency of fruit processing.

[0020] 3. In this solution, a water-repelling component is installed. Through the coordinated action of the rotating shaft, force-bearing plate, end weight block, and lifting rod, a random pushing and flipping effect is achieved on hard fruits in water. It utilizes the impact force of the water flow and the rotation of the rotating shaft to make the force-bearing plate drive the connecting block to swing, thereby randomly lifting the lifting rod and the agitator plate. This enhances the cleaning effect of hard fruits in water and increases the probability of the fruit surface being thoroughly rinsed. At the same time, the agitator plate also weakens the water flow sprayed from the shower head, protecting the soft fruits below from excessive impact and ensuring the stability and reliability of the entire cleaning process.

Detailed Implementation

[0030] 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.

[0031] Example 1: Please refer to Figures 1-8 A conveyor and washing machine for fruit processing, comprising:

[0032] The base 1 has a feeding conveyor belt 2 on its upper surface. A cleaning tank 4 is provided on the primary surface of the feeding conveyor belt 2. A water storage tank 16 is provided inside the cleaning tank 4. A water level indicator 12 is also provided on the inner side surface of the cleaning tank 4. Multiple spray nozzles 5 are provided on the upper surface of the cleaning tank 4. A water supply pipe 6 for supplying water to the spray nozzles 5 is provided on the primary surface of the spray nozzles 5. A discharge conveyor belt 3 is provided on the side surface of the cleaning tank 4 away from the feeding conveyor belt 2. A frame is provided below the feeding conveyor belt 2 and the discharge conveyor belt 3 to support them. A blower 8 is provided on the upper surface of the discharge conveyor belt 3.

[0033] During use, staff add water to the storage tank 16 from an external water source according to cleaning needs until the water level reaches the appropriate water level indicated by the water level mark 12 on the inner side surface of the cleaning tank 4. The design of the water level mark 12 allows operators to quickly and accurately adjust the water volume, ensuring cleaning effect while avoiding water waste. Then, the feeding conveyor belt 2 is started, and the fruit to be cleaned is placed on the feeding conveyor belt 2. With the continuous movement of the feeding conveyor belt 2, the fruit is smoothly transported into the interior of the cleaning tank 4. When the fruit enters the cleaning tank 4, the spray nozzles 5 start working, and water is supplied to each spray nozzle through the water supply pipe 6, forming a uniform and fine water flow to rinse the fruit in all directions. After cleaning, the fruit continues to move forward with the water flow and finally reaches the discharge conveyor belt 3 adjacent to the cleaning tank 4. At this time, the discharge conveyor belt 3 starts and transports the fruit to the next processing area. A blower 8 is installed on the upper surface of the discharge conveyor belt 3. When the fruit passes by, the blower starts and quickly removes the residual moisture on the surface of the fruit, achieving preliminary drying to facilitate subsequent processing.

[0034] The above process is the basic process of fruit processing and cleaning.

[0035] However, in the actual fruit processing industry, bubble washing machines, as a commonly used cleaning equipment, are widely used in the pre-treatment stage of various fruits. However, in practice, to accelerate processing efficiency and meet processing demands, it is common to wash different types of fruits simultaneously. These fruits often have different characteristics, such as common soft fruits (like grapes) and firm fruits (like apples). Existing bubble washing machines, typically with only one or a few water pressure adjustment levels, are insufficient to meet the cleaning needs of multiple fruits, especially when washing both soft and firm varieties. Because smaller, softer fruits have thinner skins and more delicate flesh, they are extremely sensitive to water pressure. Excessive water pressure can directly cause the fruit to crack and damage its skin, thus affecting the fruit's integrity and quality. On the other hand, larger, harder fruits have thicker skins and require higher water pressure to effectively remove surface dirt and pesticide residues. Finding a balance in water pressure when washing both types of fruits simultaneously—one that won't damage the soft fruits while ensuring the hard fruits are thoroughly cleaned—is a challenging problem. However, washing the two types of fruits separately increases the workload and processing time, leading to reduced processing efficiency.

[0036] In addition, some fruits (such as pears and peaches) have special shapes, such as concave or convex bottoms. When floating in water, these parts are often difficult to be directly rinsed by the spray nozzle 5. When in this state for a long time, the bottom of the fruit is prone to forming cleaning dead corners, and dirt and pesticide residues are difficult to be effectively removed. Although the bubble washing machine is designed with bubble disturbance and stirring devices, these devices often cannot ensure that all fruits can be evenly turned in the water when faced with fruits of different shapes. This is especially true for larger and heavier fruits, which are more difficult to turn and are more likely to form cleaning dead corners.

[0037] Therefore, based on the above problems, we first designed a cleaning mechanism, which includes a feeding component, a separating component, and a discharging component. The feeding component includes a baffle plate 10, which is set inside the cleaning tank 4. The lower surfaces on both sides of the baffle plate 10 are fixedly connected to the inner side surfaces of the cleaning tank 4. A movable plate 29 that can be raised and lowered is set on one surface of the baffle plate 10. Limiting side rods 26 are set on both sides of the movable plate 29. A shaft is set at the connection between the limiting side rods 26 and the movable plate 29. The other end of the limiting side rods 26 can slide on the side surface of the baffle plate 10. A slide rail is opened on the side surface of the baffle plate 10 to facilitate the sliding of the limiting side rods 26. Multiple fruit separating combs 27 are set on the side surface of the movable plate 29 opposite to the baffle plate 10. Multiple electric telescopic rods 28 are set on the side surface of the movable plate 29 away from the fruit separating combs 27. The electric telescopic rods 28 are set inside the frame below the feeding conveyor belt 2.

[0038] When different types of fruit need to be cleaned, multiple fruits enter the cleaning tank 4 via the feeding conveyor belt 2. As the fruit detaches from the upper surface of the feeding conveyor belt 2 and falls into the water storage tank 16, it is first blocked by the baffle plate 10 and rolls downwards onto the movable plate 29. Subsequently, the electric telescopic rod 28 is extended by a signal, causing the movable plate 29 to move upwards. The limiting side rods 26 on both sides can maintain the distance between the movable plate 29 and the baffle plate 10 during the movement. During the upward movement of the movable plate 29, the water on the sides of the movable plate 29 is released. The fruit separating comb 27 carries the fruit as it moves. Smaller, softer fruits fall through the gaps in the fruit separating comb 27 and enter the interior of the washing assembly below. Larger, harder fruits gradually lose the obstruction of the baffle plate 10 as the moving plate 29 rises, and roll down the slope of the fruit separating comb 27, falling back into the water. They then continue to move forward with the water flow. Meanwhile, the softer fruits move synchronously with them from inside the washing assembly. Finally, all fruits are scooped out of the washing tank 4 by the discharge assembly and transported to the upper surface of the discharge conveyor belt 3.

[0039] The washing assembly includes: a water flow conveyor belt 17, which is located at the center of the washing tank 4 and on the upper inner surface of the water storage tank 16. A control motor for driving the water flow conveyor belt 17 is installed inside the belt. Multiple internal support rods 20 are also installed inside the belt. Multiple water-dispelling plates 21 are also installed on the upper surface of the belt. A liftable lower washing pipe 15 is installed above the belt, and a lower feed pipe 1 is installed on one side of the lower washing pipe 15. 1. A waterproof spring rod 25 is provided at the connection between the lower feed pipe 11 and the lower cleaning pipe 15. The two sides of the lower feed pipe 11 are fixedly connected to the inner side surface of the cleaning tank 4. The inlet of the lower feed pipe 11 is located directly below the feeding component. Multiple bottom arc-shaped brackets 23 are also provided on the bottom surface of the lower cleaning pipe 15. Multiple fixed support plates 22 are also provided on the inner side surface of the cleaning tank 4. A waterproof spring rod 25 is also provided on the top of the fixed support plate 22. The top of the waterproof spring rod 25 is connected to the bottom surface of the lower cleaning pipe 15.

[0040] The separating and washing assembly is used to clean soft fruits that are separated from hard fruits. After the soft fruits fall from the surface of the feeding assembly, they fall downwards due to their own weight and enter through the upper opening of the lower feeding pipe 11. Finally, they enter the interior of the lower washing pipe 15 through the lower feeding pipe 11. Then, the water flow transmission belt 17 at the bottom of the washing tank 4 operates, and the water deflector 21 on its surface agitates the water flow, creating a continuous directional force that transports the fruits. The bottom surface of the lower washing pipe 15 is provided with multiple bottom arc-shaped frames 23. The bottom surface of the bottom arc-shaped frames 23 has an arc surface. When the water deflector 21 agitates the water flow, the impact force generated when the water flow hits the arc surface of the bottom arc-shaped frames 23 causes the lower washing pipe 15 to have an upward lifting force. During the upward movement of the lower cleaning pipe 15, the lower cleaning pipe 15 is restricted in its movement position by the waterproof spring rod 25 connected to the lower feed pipe 11 and the fixed support plate 22. With the reset effect of the waterproof spring rod 25 and the continuous water flow, it continuously shakes up and down, causing the soft fruits inside to shake up and down, so that the surface of the fruits can be fully rubbed and cleaned by the water. After the hard fruits on the water surface above are rinsed by the spray nozzle 5, the water flow is weakened by the water body and then rinses the hard fruits inside through the opening on the upper surface of the lower cleaning pipe 15. This avoids the soft fruits being directly damaged by the impact of the strong water flow. After passing through the interior of the lower cleaning pipe 15, the soft fruits exit from the other side and finally merge with the hard fruits.

[0041] The discharge assembly includes: a drain conveyor belt 7, which is located at the junction of the washing tank 4 and the discharge conveyor belt 3. A baffle plate 18 is also provided on one side surface of the washing tank 4. Multiple mounting base plates 33 are provided on the surface of the drain conveyor belt 7. A limiting base plate 30 is fixedly installed on one side surface of the mounting base plate 33. A rotatable support frame 31 is also provided on one side surface of the mounting base plate 33. A rotating shaft is provided at the connection between the support frame 31 and the mounting base plate 33. A drain mesh 32 for draining water is provided on the bottom surface of the support frame 31.

[0042] After both hard and soft fruits are washed, they arrive at one side of the washing pool 4. Then, the draining conveyor belt 7 operates, causing multiple support frames 31 to rise from below the water surface and scoop up the fruits from the water. As the draining conveyor belt 7 operates, the fruits leave the water surface. After leaving the water surface, the draining net 32 ​​can drain the water from the surface of the fruits. When the support frame 31 reaches the other side of the draining conveyor belt 7, the support frame 31 loses the restraining effect of the bottom plate 30 and tilts downwards, then pours out the fruits inside and lets them fall onto the discharge conveyor belt 3 for drying and transportation.

[0043] Meanwhile, based on the aforementioned issues, we also designed a water-dispelling assembly, which includes: multiple actuating plates 14, each actuating plate 14 located on the upper surface of the lower cleaning pipe 15, with branch actuating posts 24 on the upper surface of each actuating plate 14, and a fixed horizontal plate 13 on the upper surface of each actuating plate 14. Two liftable lifting rods 35 are located at the center of the fixed horizontal plate 13, with actuating arc plates 9 on the upper surface of each lifting rod 35. The surface of each lifting rod 35 also has anti-detachment rings 34 to prevent it from detaching from the fixed horizontal plate 13. The cleaning tank 4 also contains multiple rotating shafts 38, with a rotating shaft 38 between each fixed horizontal plate 13 and the lower cleaning pipe 15. Each end of the rotating shaft 38 has a sliding disc 19. A rotating shaft is provided between the shaft 38 and the sliding disk 19. A force-bearing plate 40 is provided on one side surface of the rotating shaft. A groove for absorbing the impact force of water flow is provided on one side surface of the force-bearing plate 40. An end load block 41 is provided on one side surface of the rotating shaft 38. A connecting block 39 is provided on one side surface of the rotating shaft 38. An arc groove that matches the two sides of the connecting block 39 is provided on the bottom surface of the lifting rod 35 and the upper surface of the branch top pile 24. An arc groove that matches the two protruding top surfaces of the upper surface of the branch top pile 24 is provided. A sliding groove that facilitates the sliding of the sliding disk 19 is provided on the inner side surface of the cleaning pool 4. A connecting spring 37 is provided on the upper surface of the sliding disk 19. A fixing block 36 is provided on the top of the connecting spring 37. The fixing block 36 is fixedly connected to the inner side surface of the cleaning pool 4.

[0044] The water-dispensing assembly is activated when the washing assembly is in operation. As the lower washing pipe 15 moves up and down with the water flow, the multiple actuating plates 14 on the upper surface of the lower washing pipe 15 also move upward. The rotating shaft 38 above the lower washing pipe 15 is also rotated by the water flow. The force-receiving plate 40 on the side surface of the rotating shaft 38 swings due to the impact of the water flow, and under the weight of the end weight block 41 on one side of the force-receiving plate 40, it swings back quickly in the opposite direction, thereby driving the rotating shaft 38 to rotate, which in turn drives the connecting block 39 to swing synchronously. When the connecting block 39 swings randomly to one side with the water flow, the lower washing pipe 15 rises and is pushed upward by one of the branch actuating plates 14 at the top, and the connecting block 39 compensates for the gap between it and the lifting rod 35. The distance is such that one of the lifting rods 35 at the center of the fixed horizontal plate 13 can rise synchronously with the current rise of the washing pipe 15 below. Since both the lifting rod 35 and the end of the branch top post 24 have two, when the connecting block 39 swings, one of the lifting rods 35 will be randomly lifted up, and the top of the arc plate 9 will push upward to apply an upward thrust to the hard fruit floating on the water surface. Combined with the impact force of the spray nozzle 5, the fruit can be more easily overturned, making it easier for the surface of the fruit to be thoroughly rinsed. The random downward thrust can make the fruit less stable in the water, increasing the probability of the fruit overturning. The upward thrust generated by the arc plate 9 can also weaken the water flow sprayed from the spray nozzle 5 to a certain extent, thereby ensuring that the soft fruit below receives a weaker impact effect and preventing it from being damaged.

[0045] The working principle of this invention is:

[0046] During use, staff add water to the water storage tank 16 through an external water source according to the cleaning needs until the water level reaches the appropriate water level line indicated by the water level mark 12 on the inner side surface of the cleaning tank 4. The design of the water level mark 12 makes it easy for operators to quickly and accurately adjust the water volume, ensuring the cleaning effect while avoiding water waste. Then, the feeding conveyor belt 2 is started, and the fruit to be cleaned is placed on the feeding conveyor belt 2. With the continuous movement of the feeding conveyor belt 2, the fruit is smoothly transported into the interior of the cleaning tank 4. When the fruit enters the cleaning tank 4, the spray nozzles 5 start to work, and the water source is supplied to each spray nozzle through the water supply pipe 6 to form a uniform and fine water flow to rinse the fruit in all directions.

[0047] When different types of fruit need to be cleaned, multiple fruits enter the washing tank 4 via the feeding conveyor belt 2. As the fruit detaches from the upper surface of the feeding conveyor belt 2 and falls into the water storage tank 16, it is first blocked by the baffle plate 10 and rolls downwards onto the movable plate 29. Subsequently, the electric telescopic rod 28 is extended by a signal, causing the movable plate 29 to move upwards. The limiting side rods 26 on both sides can maintain the distance between the movable plate 29 and the baffle plate 10 during movement. During the upward movement, the fruit separating comb 27 on the side of the movable plate 29 carries the fruit. At this time, the smaller soft fruits fall down through the gaps in the fruit separating comb 27 and enter the interior of the washing assembly below. The larger hard fruits gradually lose the obstruction of the baffle plate 10 as the movable plate 29 rises, and roll down the slope of the fruit separating comb 27 and fall into the water again. They then continue to move forward with the water flow, while the soft fruits move synchronously with them from inside the washing assembly.

[0048] After the soft fruit falls from the surface of the feeding component, it falls downwards due to its own weight and enters through the upper opening of the lower feeding pipe 11, eventually entering the interior of the lower washing pipe 15. Then, the water flow transmission belt 17 at the bottom of the washing tank 4 operates, and the water-dispelling plates 21 on its surface agitate the water flow, creating a continuous directional force that carries the fruit. The bottom surface of the lower washing pipe 15 is equipped with multiple bottom arc-shaped supports 23. The bottom surface of each support 23 has an arc shape. When the water-dispelling plates 21 agitate the water flow, the impact force generated when the water flows against the arc-shaped bottom surface of the supports 23 causes the lower washing pipe 15 to have an upward lifting force. During the activity, the lower cleaning pipe 15 is restricted in its movement position by the waterproof spring rod 25 connected to the lower feed pipe 11 and the fixed support plate 22. With the reset effect of the waterproof spring rod 25 and the continuous water flow, it continuously shakes up and down, causing the soft fruit inside to shake up and down, so that the surface of the fruit can be fully rubbed and cleaned by the water. After the hard fruit on the water surface is rinsed by the spray nozzle 5, the water flow is weakened by the water body and then rinses the hard fruit inside through the opening on the upper surface of the lower cleaning pipe 15. This avoids the soft fruit being damaged by the impact of the strong water flow. After passing through the interior of the lower cleaning pipe 15, the soft fruit comes out from the other side and finally merges with the hard fruit.

[0049] The water-dispensing assembly also starts when the washing assembly is working. As the lower washing pipe 15 moves up and down with the water flow, multiple actuating plates 14 on the upper surface of the lower washing pipe 15 also push upwards. The rotating shaft 38 above the lower washing pipe 15 is also rotated by the water flow. The force-receiving plate 40 on the side surface of the rotating shaft 38 swings due to the impact of the water flow, and under the weight of the end weight block 41 on one side of the force-receiving plate 40, it swings rapidly in the opposite direction, thereby driving the rotating shaft 38 to rotate, which in turn drives the connecting block 39 to swing synchronously. When the connecting block 39 swings randomly to one side with the water flow... The lower cleaning pipe 15 rises and is pushed upward by one of the branch top posts 24 at the top of the top of the top actuating plate 14, and the distance between it and the lifting rod 35 is compensated by the connecting block 39. This allows one of the lifting rods 35 at the center of the fixed horizontal plate 13 to rise synchronously with the rise of the lower cleaning pipe 15, making it easier for the surface of the fruit to be thoroughly rinsed. The random downward thrust can make the fruit less stable in the water, increasing the probability of the fruit tipping over. The upward thrust generated by the actuating arc plate 9 can also weaken the water flow sprayed from the spray nozzle 5 to a certain extent, thereby ensuring that the soft fruit below receives a weaker impact effect and preventing it from being damaged.

[0050] After both hard and soft fruits are washed, they arrive at one side of the washing pool 4. Then, the draining conveyor belt 7 operates, causing multiple support frames 31 to rise from below the water surface and scoop up the fruits. As the draining conveyor belt 7 operates, the fruits leave the water surface. After leaving the water surface, the draining net 32 ​​can drain the water from the surface of the fruits. When the support frames 31 reach the other side of the draining conveyor belt 7, the support frames 31 lose the restraining effect of the bottom plate 30 and tip downwards, then pour out the fruits inside and let them fall onto the discharge conveyor belt 3 for drying and transportation. A blower 8 is installed on the upper surface of the discharge conveyor belt 3. When the fruits pass by, the blower is activated to quickly remove the residual moisture on the surface of the fruits, achieving preliminary drying to facilitate subsequent processing.
