Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a drum-type fruit and vegetable washing machine. Background Technology

[0002] In the food processing and fresh produce handling industry, fruit and vegetable cleaning is a crucial preliminary step in ensuring food safety and quality. Its core requirements are efficient removal of contaminants, minimal damage to fruits and vegetables, and continuous operation. As the market demands higher processing capacity and cleaning standards for fruits and vegetables, traditional cleaning methods have gradually revealed unavoidable technical shortcomings and are unable to meet the needs of large-scale, refined production.

[0003] Currently, fruit and vegetable cleaning mainly relies on two methods: manual cleaning and simple cleaning equipment. Although manual cleaning can achieve initial cleaning through human friction, it is extremely inefficient, labor-intensive, and the cleaning effect is significantly affected by human factors, making it difficult to guarantee the consistency of batch cleaning. At the same time, it cannot effectively remove fine dirt and pesticide residues attached to the surface of fruits and vegetables, posing a food safety hazard.

[0004] Existing simple cleaning equipment mostly adopts a single spray or drum agitation structure, which also has significant limitations: First, the cleaning method is singular, relying mainly on high-pressure water jets or coarse drum agitation. This either fails to penetrate deep into the crevices of fruits and vegetables for thorough cleaning, leading to excessive pesticide residues, or causes damage to the skin and flesh of fruits and vegetables due to excessive mechanical force, significantly reducing the commercial value of the products. Second, the equipment lacks self-cleaning ability. The cage or screen of drum-type equipment is easily clogged by fruit and vegetable residue, resulting in reduced water permeability and a gradual decline in cleaning efficiency. Frequent shutdowns for manual cleaning are required, further affecting the continuity of production. Third, the degree of automation is low. Feeding and discharging often require manual assistance, which not only increases labor costs but also easily causes secondary damage to fruits and vegetables during transportation. Fourth, wastewater treatment is unreasonable. Defective design of the washing tank structure leads to the accumulation of sewage, which can easily cause secondary pollution to subsequently cleaned fruits and vegetables, failing to meet the hygiene standards for food processing.

[0015] Compared with the prior art, the technical solution described in this utility model has the following beneficial effects: 1. This utility model has the characteristics of reasonable structural design, high degree of automation, high cleaning efficiency, and high degree of collaborative operation. The integrated structure of the inclined bucket-shaped cleaning tank and the water guide tank in this utility model enables wastewater to be quickly collected and discharged, which not only avoids secondary pollution of fruits and vegetables, but also facilitates cleaning and maintenance after the equipment is shut down, and improves the service life of the equipment. 2. In this utility model, the gentle friction of the cleaning guide brush and the internal and external dual spray system work synergistically. The fine water mist from the atomizing nozzles improves the dirt removal rate, especially targeting small dirt and pesticide residues in the crevices of fruits and vegetables. At the same time, the atomizing spray reduces water consumption per unit time, and the high-pressure water flow from the outer nozzles assists in cleaning and also cleans the cage, achieving a balance between water conservation and efficient cleaning. 3. The "brushing + tapping" dual cleaning mode of the cleaning device in this utility model effectively prevents fruit and vegetable residue from clogging the water holes of the cleaning guide cage, ensuring smooth water flow during the cleaning process; the cleaning guide cage, in conjunction with the axial and radial support of the support wheel, avoids axial movement of the cleaning guide cage due to the thrust of the fruit and vegetables or its own rotational inertia, and prevents it from sagging and deforming due to its own weight and the weight of the fruit and vegetables, ensuring stable rotation of the cleaning guide cage, reducing operating noise and vibration, and supporting continuous cleaning operations; 4. The inclined extension design of the feeding conveyor channel, the gentle contact of the cleaning guide brush, the appropriate rotation speed of the cleaning guide cage, and the smooth transition of the discharge ramp in this utility model prevent fruits and vegetables from impacting or falling from heights throughout the entire process from feeding to discharging, significantly improving the integrity of the cleaned fruits and vegetables and reducing production losses; 5. In this utility model, the continuous conveying of the feeding conveyor belt and the washing guide cage, and the automatic collection of the discharging conveyor belt form an assembly line operation, reducing manual intervention; the variable frequency speed regulation function of the power unit can be adapted to the washing needs of different kinds of fruits and vegetables, improving the equipment's versatility and operational flexibility. Other beneficial effects of this invention will be further explained in the following specific embodiments. Attached Figure Description

[0020] like Figures 1 to 6 As shown, this utility model provides a drum-type fruit and vegetable washing machine. It includes an overall support frame 1 and a cleaning device, a spraying device, a cleaning device, and a power device mounted on it. The cleaning device includes an inclined cleaning tank 201 and a roller-type cleaning guide cage 202 arranged inside it. The tail end of the cleaning tank 201 is provided with a discharge ramp 203. The bottom of the cleaning tank 201 is provided with a water guide trough 204, and the bottom of the water guide trough 204 has a water outlet 205. A water collection tank 206 is provided below the water outlet 205. The cleaning guide cage 202 includes a cage body and cleaning guide rods 207 and cleaning guide brushes 208 arranged on its inner surface. The spraying device includes a spraying mechanism I 301 located outside the cleaning guide cage 202 and a spraying mechanism II 302 located inside the cleaning guide cage 202. The spraying mechanism I 301 includes a spraying pipe I 3011 and a spraying mechanism II 302 located inside the cleaning guide cage 202. The cleaning device includes a cleaning brush 401 located on the outside of the cleaning guide cage 202 and a cleaning belt 402 located above the cleaning guide cage 202. The power device includes a synchronous sprocket mechanism 501 located at the feed end of the cleaning guide cage 202, a power motor 502 connected to the synchronous sprocket mechanism 501, and a support wheel 503 for supporting the cleaning guide cage 202. A feed conveyor belt 6 is provided on one side of the cleaning device. The feed conveyor belt 6 is provided with a feed conveying channel extending into the interior of the cleaning guide cage 202. A discharge conveyor belt 7 is provided on the other side of the cleaning device. The discharge conveyor belt 7 is located below the discharge ramp 203.

[0021] In the embodiments described in this utility model, the overall support 1 provides support for the equipment on it. The overall support 1 includes a support frame I and a support frame II symmetrically arranged therewith. The washing tank 201 is located between the support frame I and the support frame II and is fixed to the upper part of the overall support 1 in an inclined manner. The structure of the washing tank 201 is set as a bucket shape. The bucket shape structure of the washing tank 201 can concentrate the wastewater generated when washing fruits and vegetables at the bottom of the washing tank 201. The discharge ramp 203 is connected to the tail end of the washing tank 201 by integral molding and extends to the bottom of the discharge end of the washing guide cage 202. When the fruits and vegetables are discharged from the washing guide cage 202, they can slide smoothly down the discharge ramp 203, effectively avoiding damage or breakage caused by the fruits and vegetables falling directly from the height of the washing guide cage 202, and significantly improving the integrity of the fruits and vegetables after washing.

[0022] In the embodiments described in this utility model, the water guide trough 204 is integrally formed and disposed at the bottom of the washing tank 201. The water guide trough 204 extends along the length direction of the washing tank 201, and an outlet 205 is provided on the bottom end face of the water guide trough 204 near the discharge slope 203. The water guide trough 204 allows the wastewater generated during the washing process to converge along the water guide trough 204 to the outlet 205 and be discharged under the influence of gravity due to the inclined arrangement of the washing tank 201. This avoids the accumulation of wastewater in the washing tank 201 and the resulting secondary pollution of fruits and vegetables. At the same time, the water guide trough 204 also facilitates cleaning and maintenance after the equipment is shut down.

[0023] In the embodiments described in this utility model, the cleaning guide cage 202 is erected and positioned inside the cleaning tank 201, and the central axis of the cleaning guide cage 202 is parallel to the central axis of the cleaning tank 201, that is, the cleaning guide cage 202 is inclined relative to the horizontal plane. The cleaning guide cage 202 is a cylindrical cage made of stainless steel, and several permeable holes are evenly opened on the surface of the cage to provide a channel for the flow of cleaning water and the discharge of sewage. The cleaning guide rods 207 are evenly distributed on the inner surface of the cleaning guide cage 202. Furthermore, the cleaning guide rod 207 is fixedly connected to the inner surface of the cleaning guide cage 202 at an angle relative to its central axis. The cleaning guide brush 208 is arranged in a staggered manner on the inner surface of the cleaning guide cage 202. The cleaning guide rod 207 can drive the fruits and vegetables to move gradually along the axis of the cage when the cleaning guide cage 202 rotates, realizing continuous cleaning operation. The cleaning guide brush 208 can provide gentle friction to the fruits and vegetables, helping to remove dirt from their surface, while effectively avoiding mechanical damage to the fruits and vegetables. Specifically, the included angle between the cleaning guide rod 207 and the central axis of the cleaning guide cage 202 ranges from 15° to 30°.

[0024] In the embodiments described in this utility model, the spraying device is connected to an external water tank via a water pump to achieve high-pressure water spraying; the spraying mechanism I 301 is fixedly connected to the top of the overall support 1 outside the cleaning guide cage 202, and its spraying pipe I 3011 is arranged along the length direction of the cleaning guide cage 202, and a plurality of nozzles 3012 are evenly distributed on the side of the spraying pipe I 3011 facing the outer side of the cleaning guide cage 202. The spraying direction of the nozzles 3012 forms a 30° angle with the tangent direction of the cleaning guide cage 202. The high-pressure water flow can directly impact the outer side of the cleaning guide cage 202 through the spraying pipe I 3011 and the nozzles 3012, which can wash away the fruit and vegetable residues attached to the surface of the cage on the one hand, and the water flow can enter the interior of the cage through the water permeable holes of the cage to perform preliminary cleaning of the surface of the fruit and vegetables on the other hand; the spraying mechanism II 302 extends from the discharge end of the cleaning guide cage 202 to the feed end of the cleaning guide cage 202, and is connected to the external support 1 via a water pump. The spraying supports at the front and rear ends of the overall bracket 1 are used to mount the spraying mechanism II 302 inside the cleaning guide cage 202, so that the spraying mechanism II 302 will not affect the continuous rotation of the cleaning guide cage 202. The spraying pipe II 3021 of the spraying mechanism II 302 is arranged parallel to the spraying pipe I 3011 of the spraying mechanism I 301, and the surface of the spraying pipe II 3021 is evenly distributed with several atomizing nozzles 3022 in a downward angle. The atomizing nozzles 3022 can convert high-pressure water into fine water mist. The water mist forms a uniform water film inside the cage and fully contacts the surface of fruits and vegetables. It can not only deeply clean the crevices and depressions on the surface of fruits and vegetables, removing attached fine dirt and pesticide residues, but also reduce the water consumption per unit time, achieving the effect of water-saving cleaning. In addition, the water circulation formed by the inner and outer double spraying structure can quickly discharge the sewage inside the cage through the water permeable holes to the water guide trough 204, further improving the cleaning efficiency.

[0025] In the embodiments described in this utility model, the cleaning device can work in conjunction with the cleaning guide cage 202 to clean the fruit and vegetable residue on the surface of the cleaning guide cage 202 in real time, preventing the residue from clogging the water permeable holes on the surface of the cage and affecting the cleaning effect. The cleaning brush 401 is located on the top surface of the overall bracket 1 opposite to the spraying mechanism Ⅰ301. The cleaning brush 401 includes a rotating shaft Ⅰ, bristles evenly distributed on the surface of the rotating shaft Ⅰ, and bearing seats Ⅰ at the head and tail ends of the rotating shaft Ⅰ. The bristles are made of nylon material. The bristles and the cleaning guide cage... The outer surface of the cleaning guide cage 202 fits tightly. The rotating shaft I of the cleaning brush 401 is connected to the cleaning motor I. When the cleaning guide cage 202 rotates, the cleaning motor I can drive the rotating shaft I to rotate synchronously in the opposite direction, thereby causing the cleaning brush 401 to roll synchronously in the opposite direction relative to the cleaning guide cage 202. The bristles can penetrate into the gaps on the surface of the cage to wash away loose fruit and vegetable residues and ensure the unobstructed drainage holes. The cleaning belt 402 is mounted directly above the cleaning guide cage 202 and is connected to the first and second ends of the overall support 1 through cleaning supports. 02 includes a rotating shaft II, beating strips evenly distributed on the surface of the rotating shaft II, and bearing seats II at both ends of the rotating shaft II. One end of the beating strip is fixed to the outer surface of the rotating shaft II, and the other end hangs down naturally and adheres to the outer side of the cleaning guide cage 202 when not rotating. When the beating strip hangs down naturally, it can extend from the position of the rotating shaft II to one-third of the radius of the cleaning guide cage 202. The rotating shaft II of the cleaning belt 402 is connected to a cleaning motor II. For tightly packed fruit and vegetable residues that are difficult to remove by the cleaning brush 401, the cleaning motor can... The cleaning motor II drives the rotating shaft II to rotate synchronously, which in turn causes the cleaning belt 402 to rotate and beat the outer surface of the cleaning guide cage 202 at high frequency. The beating action of the cleaning belt 402 can generate a vibration effect, which beats the residue out of the cage gaps of the cleaning guide cage 202. Then, the cleaning brush 401 further cleans it. The coordinated operation of the cleaning brush 401 and the cleaning belt 402 achieves dual cleaning of the residue in the cage gaps of the cleaning guide cage 202 by "brushing and beating", ensuring that the cleaning guide cage 202 always maintains good water permeability and cleaning performance.

[0026] In the embodiments described in this utility model, the power unit provides power for the rotation of the cleaning guide cage 202. The synchronous sprocket mechanism 501 includes a driven sprocket fixed to one end of the cleaning guide cage 202, a driving sprocket fixed to the output shaft of the power motor 502, and a chain surrounding the driven sprocket and the driving sprocket. The transmission ratio between the driving sprocket and the driven sprocket is 1:3. Through reduction transmission, the cleaning guide cage 202 is ensured to rotate at a suitable speed, which ensures thorough cleaning while avoiding damage to fruits and vegetables due to excessive speed. The power motor 502 is a variable frequency speed control motor, which is fixed to the bottom of the overall bracket 1 by bolts. The speed can be adjusted from 5 to 20 r / min depending on the type of fruit and vegetable and the cleaning requirements. The rotation speed is adjustable within the range of n. Four sets of support wheels 503 are symmetrically arranged below the left and right ends of the cleaning guide cage 202. All four sets of support wheels 503 are located on the inner bottom surface of the cleaning tank 201. The wheel surface of the support wheel 503 is provided with a limiting structure, which can cooperate with the limiting ring provided on the outer surface of the cleaning guide cage 202 to achieve axial limiting. The wheel surface of the support wheel 503 is in close contact with the outer surface of the cleaning guide cage 202. Its function is to provide radial support to the cleaning guide cage 202, preventing the cleaning guide cage 202 from sagging and deforming due to its own weight and the weight of the fruits and vegetables, ensuring that the cleaning guide cage 202 can rotate smoothly, and reducing noise and vibration during operation.

[0027] In the embodiments described in this utility model, the feeding conveyor belt 6 is provided with a feeding conveyor frame, which is connected to the overall support 1 by bolts. The feeding conveyor channel is located at the discharge end of the feeding conveyor belt 6. The feeding conveyor channel is made of bent stainless steel plate, and the end of the feeding conveyor channel extends into the interior of the washing guide cage 202 in an inclined form, so that fruits and vegetables can fall smoothly into the washing guide cage 202, avoiding damage caused by fruits and vegetables hitting the cage body. The feeding end of the discharge conveyor belt 7 is located below the discharge slope 203, and the height of the feeding end of the discharge conveyor belt 7 is lower than the height of the bottom edge of the discharge slope 203, ensuring that fruits and vegetables sliding down from the discharge slope 203 can fall completely onto the discharge conveyor belt 7, realizing the automatic collection and transfer of washed fruits and vegetables.

[0028] Based on the above, the working steps of this utility model are as follows: Step S1: Device Start-up and Parameter Setting After the operator starts the equipment, according to the type of fruits and vegetables to be cleaned, the appropriate speed is preset through the frequency conversion function of the power motor 502. At this time, the power motor 502 drives the active sprocket to rotate through the synchronous sprocket mechanism 501, that is, the output end of the power motor 502 drives the driven sprocket to rotate, and then drives the driven sprocket to rotate through the chain, so as to drive the cleaning guide cage 202 to rotate smoothly; the high-pressure water pump starts, so that the spraying mechanism I 301 and the spraying mechanism II 302 form a high-pressure water supply; the cleaning motor I and the cleaning motor II drive the cleaning brush 401 and the cleaning belt 402 to operate synchronously, completing the start-up preparation; Step S2: Fruit and Vegetable Feeding The fruits and vegetables to be cleaned are conveyed from the inlet end of the inlet conveyor belt 6 to the inlet conveyor channel set at the outlet end of the inlet conveyor belt 6. The inlet conveyor channel, which extends into the inside of the cleaning guide cage 202, guides the fruits and vegetables smoothly into the cleaning guide cage 202 in an inclined manner to avoid damage caused by the fruits and vegetables hitting the cage. Step S3: Collaborative Cleaning Operation The rotating cleaning guide cage 202, through the cleaning guide rods 207 arranged in a staggered pattern on its inner side, drives the fruits and vegetables to move gradually towards the discharge end along the axis of the cage, realizing continuous conveying operation. At the same time, the cleaning guide brushes 208 set on the inner side of the cage gently rub the surface of the fruits and vegetables, helping to remove dirt. During this process, the spraying device works simultaneously. The nozzles 3012 of the spraying mechanism I 301 located on the outside of the cleaning guide cage 202 spray high-pressure water jets towards the outer side of the cleaning guide cage 202 at a direction of 30° with the tangent of the cage. On the one hand, it washes the residue on the outer surface of the cage, and on the other hand, the water flows into the inside of the cage through the water permeable holes to complete the initial washing of the fruits and vegetables. The spraying mechanism II 302 located inside the cleaning guide cage 202 forms a fine water mist through the atomizing nozzles 3022, which penetrates into the gaps of the fruits and vegetables to clean small dirt and pesticide residues. The water circulation formed by the inner and outer double spraying structure accelerates the discharge of sewage. Step S4: Cage cleaning and wastewater treatment During the rotation of the cleaning guide cage 202, the cleaning device operates synchronously to ensure the water permeability of the cleaning guide cage 202. The cleaning brush 401 located on the outside of the cleaning guide cage 202 is driven by the cleaning motor I and rolls in the opposite direction to the cleaning guide cage 202. The bristles of the cleaning brush 401 penetrate into the gaps of the cage to brush away loose residue. The cleaning belt 402 located above the cleaning guide cage 202 is driven by the cleaning motor II and beats the cage at high frequency through the beating strip to shake out the tightly mixed residue. Then, the cleaning brush 401 cleans it further. The two work together to ensure that the water permeable holes on the surface of the cage are unobstructed, achieving a dual cleaning effect of "brushing + beating". The wastewater generated during cleaning is guided by the bucket-shaped cleaning tank 201 and the water guide trough 204 to the outlet 205, and finally discharged into the collection tank 206 below through the outlet 205 to avoid wastewater accumulation and secondary pollution. Step S5: Fruit and vegetable discharge and equipment shutdown The washed fruits and vegetables, driven by the washing guide rod 207, reach the discharge end of the washing guide cage 202 and are discharged from the discharge end of the washing guide cage 202. They slide smoothly down the discharge ramp 203 at the end of the washing tank 201 to the discharge conveyor belt 7 below, avoiding damage from falling from a height. They are then transferred to the subsequent stages by the discharge conveyor belt 7. After the operation is completed, the feeding conveyor belt 6, the power motor 502, and the water pump are turned off in sequence to complete the equipment cleaning and maintenance.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
