Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to intelligent mechanical equipment for fruit and vegetable cleaning. Background Technology
[0002] Fruit and vegetable washing machines are automated equipment that integrates mechanical engineering, intelligent control, and food science technology. They are designed to clean various fruits and vegetables efficiently, safely, and environmentally. Their core function is to remove pollutants such as mud, pesticide residues, and microorganisms from the surface of fruits and vegetables through physical methods (such as mechanical scrubbing, high-pressure spraying, and bubble tumbling), while maximizing the protection of the integrity of the fruit and vegetable skin, thus meeting the needs of modern large-scale agricultural processing and high food safety standards.
[0003] Existing intelligent machinery for cleaning fruits and vegetables uses a drum type, which usually relies on the unidirectional rotation of the drum to tumble the fruits and vegetables. It relies on the impact of the fruits and vegetables and water flow against the drum wall in a single direction to remove dirt. This easily creates cleaning dead corners, has limited effect on removing stubborn stains, and the drum is difficult to install and disassemble, making it difficult to deeply rinse or disinfect the inside of the drum. Dirt remains inside the drum, causing cross-contamination and making it inconvenient for the next use. Utility Model Content
[0004] This utility model addresses the technical problems of existing intelligent mechanical equipment for cleaning fruits and vegetables, which relies on unidirectional rotational friction to remove dirt, leaving dead corners and making it difficult to remove stubborn stains. Furthermore, the drum is difficult to disassemble, making it difficult to rinse and disinfect the interior and causing cross-contamination due to residual dirt. Therefore, this utility model provides intelligent mechanical equipment for cleaning fruits and vegetables.
[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:
[0006] This utility model provides a special intelligent mechanical device for fruit and vegetable cleaning, including a box body, a cover plate on the box body, a mounting shell fixedly installed on the cover plate, a motor fixedly installed on the mounting shell, a fixing shell fixedly installed around the motor, a rotating shaft fixedly installed through the mounting shell through the output shaft of the motor, a rotating cylinder fixedly installed inside the box body through the rotating shaft, a main pulley fixedly installed on the rotating shaft, a rotating rod rotatably connected between the mounting shell and the cover plate through a bearing, a driven pulley and a driving gear fixedly installed on the rotating rod, the main pulley being driven by the driven pulley through a belt, a rotating tube fixedly installed on the cover plate, a driven gear fixedly installed on the rotating tube, the driving gear meshing with the driven gear, a connecting plate fixedly installed at the bottom end of the rotating tube, and the rotating shaft being rotatably connected to the connecting plate through a bearing.
[0007] The box is equipped with a cleaning frame inside, and multiple first cleaning rods are fixedly installed inside the cleaning frame. Multiple second cleaning rods are fixedly installed on the rotating cylinder. Both the first and second cleaning rods are made of thermoplastic elastomer (TPE) material, and both the first and second cleaning rods are provided with raised and recessed textures.
[0008] In this technical solution, the cleaning frame is provided with multiple through holes that are evenly distributed.
[0009] In this technical solution, multiple auxiliary wheels are fixedly installed at the bottom of the cleaning frame, and all of the auxiliary wheels are in contact with the bottom wall of the box.
[0010] In this technical solution, a positioning ring is fixedly installed on the cleaning frame, and the positioning ring has multiple positioning holes distributed at equal intervals.
[0011] In this technical solution, multiple positioning rods are fixedly installed on the connecting plate at equal intervals, and each of the multiple positioning rods can be inserted into the positioning hole.
[0012] In this technical solution, the inside of the cleaning frame is rotatably connected to a rotating shaft via a bearing, and a rotating plate is fixedly installed at the top of the rotating shaft. The rotating plate has multiple equally spaced insertion slots.
[0013] In this technical solution, four plug-in blocks are fixedly installed on the rotating cylinder, and all four plug-in blocks can be plugged into the plug-in slot.
[0014] In this technical solution, two handles are fixedly installed on the mounting shell, and the cover plate is fixed to the box body by two latches.
[0015] In this technical solution, the box body is connected to a water inlet pipe and a water outlet pipe, and both the water inlet pipe and the water outlet pipe are equipped with valves.
[0016] In this technical solution, four support legs are fixedly installed at the bottom of the box.
[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0018] The positive and progressive effects of this utility model are as follows:
[0019] The aforementioned intelligent mechanical equipment for cleaning fruits and vegetables, by starting the motor, enables the cleaning frame and rotating drum to operate synchronously. The cleaning frame drives multiple first cleaning rods to apply lateral shearing force to the fruits and vegetables, causing them to tumble and collide with each other within the cleaning frame, removing large particles of mud or impurities attached to the surface. The rotating drum rotates in the opposite direction, and multiple second cleaning rods apply longitudinal rubbing force to the fruits and vegetables, further scrubbing their surfaces. The multiple first cleaning rods are responsible for the basic rinsing within the cleaning frame, while the multiple second cleaning rods perform secondary scrubbing of the fruits and vegetables as the rotating drum rotates. The synergistic effect of both significantly improves the efficiency of removing stubborn stains, allowing the fruits and vegetables to be subjected to a combination of lateral and longitudinal forces simultaneously within the cleaning frame, cleaning different parts of the fruits and vegetables and significantly improving cleaning efficiency.
[0020] The first and second cleaning rods are designed with thermoplastic elastomer (TPE) material, which allows them to disperse pressure through deformation when in contact with fruits and vegetables, avoiding mechanical damage to fruits and vegetables caused by sharp edges or hard surfaces. Its elastic properties allow the first and second cleaning rods to better conform to the uneven surfaces of fruits and vegetables, and enhance the tightness of contact with stains through slight deformation, thereby improving the cleaning efficiency. The uneven texture on the surface of the first and second cleaning rods can effectively remove stains such as mud and pesticide residues without damaging fruits and vegetables due to excessive friction.
[0021] By unlocking the cover and the box by using the latch, the cover can be separated from the box, and the cleaning frame can be removed separately. This allows for deep rinsing or disinfection of the cleaning frame and the rotating drum, preventing dirt residue from remaining in the box or cleaning frame and causing cross-contamination, while also ensuring hygiene for the next use.

A rotating rod 7 is rotatably connected between the mounting shell 16 and the cover plate 4 via a bearing. A driven pulley 6 and a driving gear 5 are fixedly mounted on the rotating rod 7. The main pulley 12 is connected to the driven pulley 6 via a belt 8. A rotating tube 9 is fixedly mounted on the cover plate 4. A driven gear 13 is fixedly mounted on the rotating tube 9. The driving gear 5 and the driven gear 13 are meshed together. A connecting plate 15 is fixedly mounted at the bottom end of the rotating tube 9. The rotating shaft 29 is rotatably connected to the connecting plate 15 via a bearing.
[0036] The box 1 is provided with a cleaning frame 32 inside, and a plurality of first cleaning rods 20 are fixedly installed inside the cleaning frame 32. A plurality of second cleaning rods 24 are fixedly installed on the rotating cylinder 25. The first cleaning rods 20 and the second cleaning rods 24 are both made of thermoplastic elastomer TPE material, and the first cleaning rods 20 and the second cleaning rods 24 are provided with concave and convex textures.
[0037] In this technical solution, the cleaning frame 32 is provided with a plurality of through holes 21 that are evenly distributed.
[0038] In this technical solution, a plurality of auxiliary wheels 22 are fixedly installed at the bottom end of the cleaning frame 32, and the plurality of auxiliary wheels 22 are in contact with the bottom wall of the box body 1.
[0039] In this technical solution, a positioning ring 2 is fixedly installed on the cleaning frame 32, and the positioning ring 2 has a plurality of positioning holes 18 distributed at equal intervals.
[0040] In this technical solution, a plurality of positioning rods 3 are fixedly installed on the connecting plate 15 at equal intervals, and all of the positioning rods 3 can be inserted into the positioning holes 18.
[0041] In this technical solution, the inside of the cleaning frame 32 is rotatably connected to a rotating shaft 27 via a bearing, and a rotating plate 28 is fixedly installed at the top of the rotating shaft 27. The rotating plate 28 has multiple equally spaced insertion slots 33.
[0042] In this technical solution, four plug-in blocks 26 are fixedly installed on the rotating cylinder 25, and all four plug-in blocks 26 can be plugged into the plug-in slot 33.
[0043] In this technical solution, two handles 14 are fixedly installed on the mounting shell 16, and the cover plate 4 is fixed to the box body 1 by two latches 17.
[0044] In this technical solution, the housing 1 is connected to a water inlet pipe 19 and a drain pipe 31, and both the water inlet pipe 19 and the drain pipe 31 are equipped with valves 30.
[0045] In this technical solution, four support legs 23 are fixedly installed at the bottom of the box body 1.
[0046] In use, all electrical components are externally connected to a power supply and control switch. A programmable logic controller integrates multiple parameter sensors, such as motor speed, water pressure, and temperature, to monitor the cleaning status in real time and automatically adjust. The fruits and vegetables to be cleaned are placed in the cleaning frame 32, the valve 30 is opened, and a predetermined amount of water is pre-injected into the tank 1 through the water inlet pipe 19, covering the fruits and vegetables. This allows multiple positioning rods 3 to be inserted into the positioning holes 18, and insertion blocks 26 to be inserted into the insertion slots 33. The cover plate 4 and the tank 1 are then fixed by the latch 17. The control system drives the motor, causing the cleaning frame 32 and the rotating drum 25 to rotate synchronously. The cleaning frame 32 drives the first cleaning rod 20 on its inner wall to apply a lateral shearing force to the fruits and vegetables, causing them to tumble and collide within the cleaning frame, peeling off large particles of mud or impurities adhering to the surface. The rotating drum 25 rotates in the opposite direction, causing the second cleaning rod 20 to apply a shearing force to the fruits and vegetables. The longitudinal rubbing force further scrubs the surface of fruits and vegetables. The cleaning rods on the cleaning frame 32 are responsible for the basic rinsing inside the cleaning frame. The second cleaning rod 24 on the rotating drum rotates with the rotating drum to perform a secondary scrubbing of the fruits and vegetables. The synergistic effect of the two can significantly improve the removal efficiency of stubborn stains. The first cleaning rod 20 and the second cleaning rod 24 work at the same time. When the fruits and vegetables roll in the cleaning frame 32, they are subjected to a combination of horizontal and longitudinal forces, cleaning different parts of the fruits and vegetables and significantly improving cleaning efficiency. After cleaning, the valve 30 on the drain pipe 31 is opened to discharge the sewage. The lock 17 is used to release the lock between the cover plate 15 and the box 1, and the cover plate 15 is separated from the box 1. The cleaning frame 32 can be taken out separately, which is convenient for deep rinsing or disinfection of the cleaning frame 32 and the rotating drum 25 respectively. This avoids dirt residue in the box 1 or the cleaning frame 32, which may cause cross-contamination and also ensures hygiene for the next use.
[0047] The first cleaning rod 20 and the second cleaning rod 24 are designed with thermoplastic elastomer (TPE) material, which allows them to disperse pressure through deformation when in contact with fruits and vegetables, avoiding mechanical damage to the fruits and vegetables caused by sharp edges or hard surfaces. Their elastic properties allow the first cleaning rod 20 and the second cleaning rod 24 to better conform to the uneven surface of fruits and vegetables, and enhance the tightness of contact with stains through slight deformation, thereby improving the cleaning efficiency. The uneven texture on the surface of the first cleaning rod 20 and the second cleaning rod 24 can effectively remove stains such as mud and pesticide residues without damaging fruits and vegetables due to excessive friction.
[0048] The advantages of this application are:
[0049] 1. By starting the motor 11, the washing frame 32 and the rotating drum 25 operate synchronously. The washing frame 32 drives multiple first washing rods 20 to apply a lateral shearing force to the fruits and vegetables, causing them to tumble and collide with each other within the washing frame 32, peeling off large particles of mud or impurities attached to the surface. The rotating drum 25 rotates in the opposite direction, and multiple second washing rods 24 apply a longitudinal rubbing force to the fruits and vegetables, further scrubbing the surface of the fruits and vegetables. The multiple first washing rods 20 are responsible for the basic rinsing within the washing frame, while the multiple second washing rods 24 perform a secondary scrubbing of the fruits and vegetables as the rotating drum 25 rotates. The synergistic effect of the two can significantly improve the removal efficiency of stubborn stains, so that the fruits and vegetables are simultaneously subjected to a combination of lateral and longitudinal forces within the washing frame 32, cleaning different parts of the fruits and vegetables and significantly improving cleaning efficiency.
[0050] 2. The design of the first cleaning rod 20 and the second cleaning rod 24 using thermoplastic elastomer (TPE) material allows them to disperse pressure through deformation when in contact with fruits and vegetables, avoiding mechanical damage to the fruits and vegetables caused by sharp edges or hard surfaces. Their elastic properties allow the first cleaning rod 20 and the second cleaning rod 24 to better conform to the uneven surface of the fruits and vegetables. Through slight deformation, they enhance the tightness of contact with stains and improve the cleaning efficiency. The uneven texture on the surface of the first cleaning rod and the second cleaning rod can effectively remove stains such as mud and pesticide residues without damaging the fruits and vegetables due to excessive friction.
[0051] 3. By unlocking the cover plate 4 and the box body 1 through the latch 17, the cover plate 4 can be separated from the box body 1, and the cleaning frame 32 can be taken out separately. This makes it convenient to deeply rinse or disinfect the cleaning frame 32 and the rotating drum 25 separately, avoiding dirt residue in the box body 1 or the cleaning frame 32 from causing cross-contamination, and also ensuring hygiene for the next use.
