[0006] According to one embodiment of this utility model, the aforementioned first guide rail adjustment device includes: an adjustment plate connected to the shaft of the soft brush roller; a fixed plate connected to the adjustment plate via several telescopic rods; a slide rail plate that slides in cooperation with the fixed plate via a first slide rail mechanism and is fixed to the inner wall of the outer shell; a slide track plate located between the two slide rail plates and fixed to the inner wall of the outer shell; a trapezoidal slide track located on the slide track plate; an L-shaped support rod fixed to the upper part of the adjustment plate; and a sliding wheel located at one end of the support rod and sliding in cooperation with the trapezoidal slide track. Through the above scheme, the cooperation of the trapezoidal slide track and the sliding wheel, combined with the telescopic rod and the slide rail mechanism, enables precise displacement and angle adjustment of the soft brush roller in the horizontal and vertical directions, allowing for smooth switching with the hard brush roller. This achieves precise and flexible adjustment of the soft brush roller, adapting to the cleaning needs of fruits and vegetables whose outer skin is easily damaged, improving the cleaning effect and the applicability of the device.

[0007] According to one embodiment of the present invention, the aforementioned second guide rail adjustment device includes: a slide plate connected to the shaft of the hard brush roller; a slide rod disposed on the outer wall of the outer shell; an electric slider fixedly connected to the side wall of the slide plate and sliding in cooperation with the slide rod; and a second slide rail mechanism disposed at the bottom of the slide plate and sliding in cooperation with the outer shell. By connecting the slide plate to the shaft of the hard brush roller and cooperating with the slide rod fixed to the outer wall of the outer shell, the linear motion adjustment of the hard brush roller is realized, making its movement process smoother and more automated. At the same time, it also allows the soft brush roller to pass smoothly when switching to it for cleaning, and thus performs precise positioning according to cleaning requirements.

[0008] According to one embodiment of the present invention, the belt adjustment device includes: four pulleys disposed on the inner wall of the outer casing; a tension pulley disposed on the inner wall of the outer casing and between two pulleys; a first fixing block fixedly connected to the upper belt outside the pulleys and fixed to the top of the slide plate; and a second fixing block fixedly connected to the lower belt outside the pulleys and fixed to the top of the fixing plate. Through the above scheme, the synergistic effect of the four pulleys and the tension pulley, as well as the fixing block on the belt, allows the operator to more conveniently adjust the distance between the soft and hard brush rollers according to the size and shape of different fruits and vegetables, ensuring that they always clean the fruits and vegetables at the optimal spacing. It also ensures that the brush rollers exert a balanced force on the fruits and vegetables during the cleaning process, avoiding insufficient cleaning or excessive wear in certain areas.

[0009] According to one embodiment of this utility model, the aforementioned first motor drive device includes: a first motor fixed to the top of the adjustment plate, and a first belt rotating device that rotates in cooperation with the first motor and the soft brush roller. Through the above scheme, it is ensured that the soft brush roller can maintain a constant speed and stable rotational force during the cleaning process, thereby uniformly brushing the surface of fruits and vegetables, effectively removing mud, dust and minor stains without damaging the fruits and vegetables. At the same time, since the motor directly drives the soft brush roller to rotate, a complex transmission structure is avoided, the failure rate is reduced, and the reliability and maintenance convenience of the equipment are improved.

[0010] According to one embodiment of this utility model, the second motor drive device includes: a third slide rail fixed to the outer wall of the housing, a third slider cooperating with the third slide rail, a second motor fixed on the third slider, and a third belt rotating device cooperating with the second motor and the hard brush roller to rotate. Through the above scheme, the third belt rotating device ensures stable and efficient power transmission between the second motor and the hard brush roller, and ensures that the hard brush roller can maintain a stable speed and strong brushing force at different positions. The modular design also facilitates the installation, maintenance and upgrading of the equipment, further improving the practicality and reliability of the entire fruit and vegetable cleaning device.

[0011] According to one embodiment of this utility model, the first motor and the third motor are both electrically connected to the control box. Through the above scheme, precise centralized control of the soft brush roller and the hard brush roller is realized, which greatly improves the automation level and ease of operation of the entire fruit and vegetable cleaning device. The speed of the brush roller can be preset or adjusted in real time in the control box to achieve the best cleaning effect, which can not only powerfully remove stubborn stains, but also avoid damage to delicate fruits and vegetables.

[0012] According to one embodiment of this utility model, the minimum distance between the adjusting plate and the fixed plate is configured to be greater than the outer diameter of the first motor. Through the above solution, sufficient installation space is ensured for the first motor between the adjusting plate and the fixed plate, avoiding installation difficulties, component interference or forced compression caused by insufficient space, thereby simplifying the assembly process of the equipment and reducing production costs. At the same time, it effectively prevents the first motor from colliding with the adjusting plate or the fixed plate during the adjustment of the soft brush roller, ensuring the safety and stability of the motor during normal operation and avoiding mechanical failure and potential damage.

[0013] According to one embodiment of the present invention, the highest point of the side wall of the outer shell is set to be higher than the lowest point of the outer wall of the soft brush roller when the adjustment plate is at its highest position. Through the above solution, it is ensured that the soft brush roller avoids collision with the hard brush roller when the soft brush roller is adjusted to its highest position, thereby improving the safety of the equipment.

[0014] According to one embodiment of this utility model, the bristles of the soft brush roller are made of silicone material, suitable for cleaning fruits and vegetables with easily damaged peels; the bristles of the hard brush roller are made of hard nylon material, suitable for cleaning root vegetables. This solution avoids the drawback of traditional single brush heads that cannot meet the cleaning needs of fruits and vegetables with different hardness levels.

By connecting the slide plate 1042 to the shaft of the hard brush roller 103 and cooperating with the slide rod 1043 fixed on the outer wall of the housing 107, the linear motion adjustment of the hard brush roller 103 is realized, making its movement process smoother and more automated. At the same time, it also allows the soft brush roller 102 to pass smoothly when switching to it for cleaning, and thus performs precise positioning according to cleaning requirements.

[0043] The aforementioned belt adjustment device 109 includes: four pulleys 1092 disposed on the inner wall of the outer casing 107; a tension pulley 1093 disposed on the inner wall of the outer casing 107 and between two pulleys 1092; a first fixing block 1091 fixedly connected to the upper belt outside the pulleys 1092 and fixed to the top of the slide plate 1042; and a second fixing block 1094 fixedly connected to the lower belt outside the pulleys 1092 and fixed to the top of the fixing plate 1013. Through the above scheme, the synergistic effect of the four pulleys 1092 and the tension pulley 1093, as well as the fixing block on the belt, allows the operator to more conveniently adjust the distance between the soft and hard brush rollers 103 according to the size and shape of different fruits and vegetables, ensuring that they always clean the fruits and vegetables at the optimal spacing, and also ensuring the balanced force of the brush rollers on the fruits and vegetables during the cleaning process, avoiding insufficient cleaning or excessive wear in some areas.

[0044] The aforementioned first motor drive device 106 includes: a first motor 1062 fixed to the top of the adjusting plate 1012, and a first belt drive device 1061 that rotates in cooperation with the first motor 1062 and the soft brush roller 102. Through the above scheme, it is ensured that the soft brush roller 102 can maintain a constant speed and stable rotational force during the cleaning process, thereby evenly brushing the surface of fruits and vegetables, effectively removing mud, dust and minor stains, without damaging the fruits and vegetables; at the same time, since the motor directly drives the soft brush roller 102 to rotate, a complex transmission structure is avoided, the failure rate is reduced, and the reliability and maintenance convenience of the equipment are improved.

[0047] The minimum distance between the adjusting plate 1012 and the fixed plate 1013 is configured to be greater than the outer diameter of the first motor 1062. This design ensures that the first motor 1062 has sufficient installation space between the adjusting plate 1012 and the fixed plate 1013, avoiding installation difficulties, component interference, or forced compression due to insufficient space. This simplifies the equipment assembly process and reduces production costs. At the same time, it effectively prevents the first motor 1062 from colliding with the adjusting plate 1012 or the fixed plate 1013 during the adjustment of the soft brush roller 102, ensuring the safety and stability of the motor during normal operation and avoiding mechanical failures and potential damage.

Through the above scheme, it is ensured that the soft brush roller 102 avoids collision with the hard brush roller 103 when the soft brush roller 102 is adjusted to the highest position, thereby improving the safety of the equipment.

[0049] The soft brush roller 102 has bristles made of silicone, suitable for cleaning fruits and vegetables with easily damaged peels; the hard brush roller 103 has bristles made of hard nylon, suitable for cleaning root vegetables. This design avoids the drawback of traditional single brush heads that cannot meet the cleaning needs of fruits and vegetables with different hardness levels. By combining soft and hard brushes, it ensures that all kinds of fruits and vegetables are thoroughly and without damage. This tiered cleaning design significantly improves the versatility and cleaning efficiency of the equipment, while also reducing the loss rate of fruits and vegetables during the cleaning process.

[0050] Working principle:

[0051] Take fruits and vegetables with easily damaged peels as an example:

[0052] Fruits and vegetables enter from the left side of washing tank 2, as per [reference]. Figure 7 , 89. Adjust the control box 3 so that the electric slider 1041 drives the slide plate 1042 connected to the hard brush roller 103 to move to the left. The hard brush roller 103 drives the first fixed block 1091 to move in the same direction, which in turn drives the second fixed block 1094 of the lower belt to move in the opposite direction. At the same time, the rolling wheel connected to the soft brush roller 102 rolls in the opposite direction along the trapezoidal slide 1017. The L-shaped support rod 1015 drives the telescopic rod 1011 to extend and retract along the trajectory of the trapezoidal slide 1017, which in turn lifts the soft brush roller 102 upward and passes through the space between the hard brush roller 103 and the lower part of the outer shell 107 to move further in the opposite direction. When the rolling wheel reaches the end of one end of the trapezoidal slide 1017, the control box 3 stops the movement of the electric slider 1041, so that the soft brush roller 102 is adjusted to the front of the conveyor device 7 to clean the fruits and vegetables. Adjust the control box 3 again to drive the first motor drive device 106 to adjust the rotation speed so that the silicone bristles can perform a preliminary cleaning of fruits and vegetables with easily damaged peels, gently removing surface mud and light stains.

[0053] Fruits and vegetables pre-treated by the soft brush roller 102 are then conveyed to the high-pressure cleaning device 8. The high-pressure cleaning device 8 sprays a strong water stream to perform a secondary rinse on the surface of the fruits and vegetables, thoroughly removing residual mud and most of the dirt, ensuring a thorough cleaning. Wastewater and impurities generated during the cleaning process fall to the bottom of the cleaning tank 2 and undergo preliminary filtration through the impurity collection basket 6 inside the supporting housing 5, collecting larger impurities. The water circulation system 4 is connected to the impurity collection basket 6 and the cleaning tank 2 to filter, purify, and recycle the cleaning water, effectively saving water resources and conforming to environmental protection principles.

[0054] Take root vegetables and fruits and vegetables with stubborn stains as examples:

[0055] Fruits and vegetables enter from the left side of the washing tank 2. Adjusting the control box 3 causes the electric slider 1041 to drive the slide plate 1042 connected to the hard brush roller 103 to move to the right. The hard brush roller 103 drives the first fixed block 1091 to move in the same direction, which in turn drives the second fixed block 1094 of the lower belt to move in the opposite direction. At the same time, the rolling wheel connected to the soft brush roller 102 rolls in the opposite direction along the trapezoidal slide 1017. The L-shaped support rod 1015 drives the telescopic rod 1011 to extend and retract along the trajectory of the trapezoidal slide 1017, which in turn lifts the soft brush roller 102 upward and passes through the space between the hard brush roller 103 and the lower part of the outer shell 107 to move further in the opposite direction. When the rolling wheel reaches the end of one end of the trapezoidal slide 1017, the control box 3 stops the movement of the electric slider 1041, realizing the adjustment of the soft brush roller 102 to the front of the conveyor device 7 to clean the fruits and vegetables. Adjusting the control box 3 again drives the first motor drive device 106, which is a preliminary cleaning of the fruits and vegetables by the hard nylon bristles to remove surface mud and light stains.

[0056] Fruits and vegetables pre-treated by the hard brush roller 103 undergo a second rinse by the high-pressure cleaning device 8 to thoroughly remove any remaining mud, sand, and most of the dirt, ensuring a thorough cleaning. After cleaning, they are transported to a fruit and vegetable collection basket for convenient subsequent processing. Furthermore, the position of the brush roller cleaning device 1 can be flexibly adjusted according to actual needs to adapt to the cleaning requirements of different fruits and vegetables, further improving cleaning efficiency and quality.
