Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a cleaning device for potatoes. Background Art

[0002] Potatoes are annual herbaceous plants of the Solanaceae family, and their tubers are edible. They are the fourth most important food crop globally. With the increasing attention of people to food safety and quality, and the rapid development of the potato deep processing industry, the requirements for potato cleaning technology have also been gradually improved. Traditional potato cleaning methods, such as manual cleaning or simple watering cleaning, have many deficiencies. Their cleaning efficiency is low, time-consuming, and it is difficult to thoroughly remove the soil, impurities, and dirt in the bud eyes on the potato surface, which is likely to affect the quality and taste of subsequent processed products.

[0003] The applicant retrieved and obtained the following prior art. Specifically, the patent with the publication number CN215775408U discloses a drum-type potato cleaning machine, including a fixed cylinder. A motor is fixedly installed at the bottom of the fixed cylinder. The output shaft of the motor penetrates the bottom of the fixed cylinder and extends into the interior of the fixed cylinder. One end of the output shaft of the motor extending into the interior of the fixed cylinder is fixedly connected to a rotating cylinder. A plurality of through holes are formed in the side wall of the rotating cylinder. A sewage pipe is fixedly inserted at the bottom of the fixed cylinder. One end of the bottom of the sewage pipe is fixedly connected to a wastewater tank. A filter screen is fixedly connected inside the wastewater tank and located at the bottom of the sewage pipe. A delivery pipe is fixedly inserted into the side wall of the wastewater tank and located at the bottom of the filter screen. A water pump is fixedly installed inside the delivery pipe.

[0031] Embodiment 1:

[0032] The present utility model provides a cleaning device for potatoes.

[0033] In an embodiment of the present utility model, a cleaning device for potatoes includes a frame 1 and a water supply system arranged on the frame 1. It further includes a drum 2, a flushing assembly, and a cleaning assembly. A cleaning tank 3 is arranged on the frame 1. Discharge pipes 4, water outlet pipes 5, and a feed hopper 6 are arranged at intervals on the side wall of the cleaning tank 3. The drum 2 is rotatably installed in the cleaning tank 3. The feed hopper 6 is communicated with one end of the drum 2. An outlet 7 is formed at the position of the other end of the drum 2 corresponding to the discharge pipe 4. Inner spiral vanes 8 and outer spiral vanes 9 are respectively formed on the inner wall and the outer wall of the drum 2. The flushing assembly is communicated with the water supply system and penetrates through the drum 2. The cleaning assembly is detachably installed on the side wall of the cleaning tank 3 and is used for cleaning the outer spiral vanes 9.

[0034] Specifically, as Figures 1 to 5As shown, in the utility model, a washing device for potatoes, the frame 1 can be used as a supporting structure of the entire device, thereby ensuring the placement stability and reliability of the utility model during use. Further, since a drum 2 is rotatably installed in the washing tank 3 on the frame 1, one end of the drum 2 is connected to the feed hopper 6, and the other end of the drum 2 is provided with a discharge port 7 corresponding to the position of the discharge pipe 4, the feed hopper 6 is docked or connected with the external conveying device, so that the automatic feeding of the utility model can be realized, that is, when the potatoes are transported to the feed hopper 6 by the external conveying device, they can fall into the drum 2 through the feed hopper 6, and the structural design is simple and reasonable; at the same time, the rotatable driving mode of the drum 2 can be motor driven (such as the output end of the motor and the drum 2 are connected by belt drive or chain drive), when the potatoes enter the drum 2, since the inner spiral blades 8 are formed on the inner wall of the drum 2, the potatoes can be continuously rolled and moved to the discharge pipe 4 under the rotation of the drum 2. During this process, since a flushing component is provided in the drum 2, the flushing component is connected to the water supply system, and the potatoes are in a rolling state, the potatoes in the drum 2 can be fully cleaned by the flushing component, and impurities such as soil, sand and stones attached to the surface of the potatoes can be effectively removed, thereby ensuring the cleaning effect of the potatoes and being reliable to use.

[0035] It can be understood that during the potato washing process, the flushing component flushes the impurities attached to the surface of the potatoes out of the drum 2, and since the outer spiral blades 9 are formed on the outer wall of the drum 2, as the drum 2 rotates continuously, the outer spiral blades 9 can push the impurities to the water outlet pipe 5, thereby realizing the self-cleaning function of the utility model, that is, automatically removing the impurities, without the need for the staff to manually clean the impurities in the cleaning tank 3 regularly, which not only reduces the labor intensity of the staff, but also improves the cleaning efficiency. In addition, the utility model can transport the washed potatoes to the next process by arranging a collection bucket or a conveying device at the discharge pipe 4, and by placing a sewage bucket at the water outlet pipe 5 or connecting the water outlet pipe 5 to the water supply system, it can not only realize the continuous processing of potatoes, but also collect or reuse the sewage (after filtering the sewage). Obviously, the utility model can automatically clean potatoes and automatically remove impurities such as soil, sand and stones during use, meeting the needs of continuous cleaning and processing of potatoes, and effectively reducing the frequency of equipment shutdown maintenance, making the utility model particularly suitable for automated production lines for deep processing of potatoes, and has high practicality.

[0036] It is worth noting that since a cleaning component is detachably installed on the side wall of the cleaning tank 3, the cleaning component can be a brush 10 in the prior art. When the drum 2 rotates, the cleaning component can automatically clean impurities such as dirt, sand and stones attached to the outer spiral blade 9, effectively improving the self-cleaning effect of the utility model.

[0037] It should be noted that the drum 2 is made into a mesh hollow structure that is well-known and common in the prior art. This not only meets the water drainage requirements of the drum 2 for potatoes, but also enables impurities to be washed out of the drum 2 under the action of the flushing assembly, effectively preventing phenomena such as water accumulation or impurity accumulation inside the drum 2. In addition, a control system is also provided on the frame 1. The control system and the water supply system are both mature prior arts and will not be elaborated here, and the specific structural composition is not shown in the attached drawings of the specification. The present utility model is only aimed at solving the problems of the existing potato cleaning equipment, which is likely to reduce the cleaning effect on potatoes, difficult to automatically remove impurities, not only increasing the labor intensity of workers, but also reducing the cleaning efficiency, and being inapplicable to the automated production line for deep processing of potatoes.

[0038] In one embodiment, a limiting step is provided on the side wall of the cleaning tank 3 along its extending direction. The cleaning assembly includes a brush 10 and a plurality of pressing plates 11. The brush 10 is placed on the step surface of the limiting step and is used to clean the outer spiral blade 9. The plurality of pressing plates 11 are respectively detachably installed on the limiting step through a locking member, and the plurality of pressing plates 11 are evenly and spaced along the extending direction of the limiting step and are used to press the brush 10.

[0039] Specifically, as Figures 2 to 5 shown, since a limiting step is provided on the side wall of the cleaning tank 3 along its extending direction, the limiting step not only provides an installation basis for the cleaning assembly, but also ensures the stability and positioning accuracy of the cleaning assembly after installation. Further, since the plurality of pressing plates 11 are respectively detachably installed on the limiting step through a locking member, the locking member can be selected as a screw or a buckle in the prior art. When the brush 10 is placed in place, at this time, the worker can operate the locking member to firmly press the brush 10 onto the limiting step, and the operation is simple and convenient. It can be understood that since the plurality of pressing plates 11 are evenly and spaced along the extending direction of the limiting step, the plurality of pressing plates 11 can achieve multi-point limiting of the brush 10 and apply a uniform pressing force to the brush 10, thereby ensuring the limiting effect on the brush 10 and preventing the brush 10 from moving or jumping when cleaning the outer spiral blade 9. In addition, the worker can remove the locking member to loosen the pressing and limiting of the brush 10 by the pressing plate 11, which is convenient for the worker to disassemble, clean or replace the brush 10.

[0040] In one embodiment, as Figures 1 to 4As shown, the outer spiral blade 9 abuts against the wall of the cleaning tank 3. The outer spiral blade 9 is used to push sewage towards the water outlet pipe 5. The water outlet pipe 5 is connected to the water supply system through a filtering component. It can be understood that since the outer spiral blade 9 abuts against the wall of the cleaning tank 3, it can not only ensure the pushing effect on sewage and impurities, reduce the residue of sewage and impurities in the cleaning tank 3, but also help to extend the cleaning and maintenance cycle of the equipment. Further, the sewage generated during the cleaning process can be discharged out of the cleaning tank 3 through the water outlet pipe 5. Since the water outlet pipe 5 is connected to the water supply system through a filtering component, the sewage can then flow back into the water supply system after being filtered by the filtering component. Thus, the utility model realizes the recycling of water resources and reduces the impact on the environment, meeting the requirements of efficient and environmental protection. It is worth noting that the filtering component includes but is not limited to filters and control valves, etc. The filtering component is a mature existing technology and a commonly used technical means, which will not be elaborated here.

[0041] In one embodiment, a boss 12 is formed at the bottom of the cleaning tank 3. A driving member 13 is detachably installed on the boss 12. The drum 2 includes a mesh drum 14 and a limiting part 15 and a movable part 16 respectively arranged at both ends of the mesh drum 14. The limiting part 15 is rotatably connected to the wall of the cleaning tank 3, and the movable part 16 is in transmission connection with the driving member 13. A connecting pipe 17 is arranged inside the movable part 16. One end of the connecting pipe 17 away from the movable part 16 passes through the side wall of the cleaning tank 3 and is detachably connected to the feed hopper 6.

[0042] Specifically, as Figure 2 and Figure 4 shown, the boss 12 at the bottom of the cleaning tank 3 can provide a relatively stable installation position for the driving member 13, effectively preventing the driving member 13 from being damaged due to the erosion of sewage or impurities. Further, since the limiting part 15 in the drum 2 is rotatably connected to the wall of the cleaning tank 3, one end of the drum 2 can be limited. At the same time, the movable part 16 is in transmission connection with the driving member 13, and a connecting pipe 17 is arranged inside the movable part 16. One end of the connecting pipe 17 away from the movable part 16 passes through the side wall of the cleaning tank 3 and is detachably connected to the feed hopper 6. Thus, the other end of the drum 2 can be limited to ensure the stability of the drum 2 during rotation and ensure the conveying and cleaning effect of the potatoes. It is worth noting that a slope is formed on the inner wall of the connecting pipe 17, so that the potatoes can smoothly enter the drum 2 from the feed hopper 6 through the connecting pipe 17, effectively preventing the potatoes from piling up in the connecting pipe 17. In addition, the way of the movable part 16 being in transmission connection with the driving member 13 is by gear transmission. Gear transmission is stable, has a compact structure, and has a relatively constant transmission ratio, which helps to drive the drum 2 to rotate smoothly, and the structural design is simple and reasonable.

[0043] In one embodiment, specifically, as Figures 2 to 5As shown, a number of positioning wheels 18 are detachably installed on the tank wall of the cleaning tank 3 corresponding to the position of the limiting part 15. The number of positioning wheels 18 is arranged at intervals and is used to abut against the limiting part 15, so as to provide multi-point limiting support for the limiting part 15, and all the positioning wheels 18 can rotate synchronously with the drum 2, thereby ensuring that the drum 2 rotates smoothly relative to the cleaning tank 3. It should be noted that the number and installation position of the positioning wheels 18 should be determined according to the actual size of the limiting part 15 of the drum 2 to ensure the limiting support effect of the positioning wheels 18 on the drum 2.

[0044] In one embodiment, the flushing assembly includes an infusion tube 19 and a number of nozzles. One end of the infusion tube 19 is connected to the water supply system, and the other end of the infusion tube 19 passes through the connecting tube 17 and extends into the mesh drum 14. The number of nozzles is evenly and spacedly arranged on the infusion tube 19 along the extending direction of the mesh drum 14 and is used to spray water into the mesh drum 14. It can be understood that, as Figures 2 to 4 shown, by connecting the infusion tube 19 to the water supply system, the infusion tube 19 can convey the clear water in the water supply system to the inside of the drum 2, and the structural design is simple and reasonable. Further, since the number of nozzles is evenly and spacedly arranged on the infusion tube 19 along the extending direction of the mesh drum 14, the clear water in the infusion tube 19 can be sprayed onto the potatoes in the mesh drum 14 through the nozzles to wash the potatoes comprehensively, and the cleaning blind area can be reduced through the nozzles to ensure the cleaning effect on the potatoes.

[0045] In one embodiment, it further includes a top cover 20. The top cover 20 is rotatably installed on the frame 1 and is used to cover the inner cavity of the cleaning tank 3, and a handle is provided on the side wall of the top cover 20. Specifically, as Figures 1 to 5 shown, during the use of the present utility model, the cleaning tank 3 can be covered by closing the top cover 20 to prevent the outer spiral blade 9 from driving sewage to splash and pollute the working environment of the workshop; at the same time, it is convenient for the staff to maintain and repair components such as the drum 2 and the driving member 13 by opening the top cover 20. Further, since a handle is provided on the side wall of the top cover 20, it is convenient for the staff to open or close the top cover 20, and the operation is convenient.

[0046] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
