Description

Technical Field

[0001] This invention relates to the technical field of leafy vegetable cleaning, and in particular to a rotary leafy vegetable cleaning device. Background Technology

[0002] With the continuous improvement of living standards and optimization of dietary structure in my country, leafy greens (such as cabbage and romaine lettuce) have become an indispensable ingredient on the daily dining table due to their rich nutrition and refreshing taste. In recent years, the pre-processed vegetable industry has developed rapidly, and large supermarkets, fresh food e-commerce platforms, and central kitchens for catering have increasingly higher demands for standardized, clean, and preserved leafy greens.

[0003] In existing technologies, leafy vegetables are cleaned using manual methods and automated equipment. The drawbacks of both methods are as follows:

[0004] 1. Manual washing of leafy vegetables is inefficient, and the quality of washing may be inconsistent due to the different washing workers.

[0005] 2. Many existing automated equipment do not thoroughly clean leafy vegetables, easily damage the leaves, fail to drain properly, and have fragmented processes, making it difficult to meet the overall requirements of modern leafy vegetable processing for cleaning quality and safety. Summary of the Invention

[0006] The present invention aims to provide a rotary leafy vegetable washing device to achieve efficient and thorough washing of leafy vegetables, stabilize the washing quality of leafy vegetables, reduce the loss of leafy vegetables during the washing process, fully drain the water from the leafy vegetables, and centralize the leafy vegetable washing process.

[0007] Therefore, the technical solution adopted by the present invention is as follows: a rotary leafy vegetable washing device, including a frame, on which a central column and a power motor are fixedly installed, and a conical water collection plate is rotatably installed. The central column is located inside the conical water collection plate. The power motor is driven and connected to the conical water collection plate and electrically connected to a control module so that the conical water collection plate rotates relative to the central column.

[0008] A ring-shaped guide rail is fixedly installed at the upper end of the central column. Around the central column, a feeding area, an ultrasonic cavitation soaking area, a brushing area, an air-vibration drying area, a detection area, and a discharging area are arranged in sequence. A feeding lifting mechanism, an ultrasonic cavitation soaking mechanism, a brushing mechanism, an air-vibration drying mechanism, a detection mechanism, and a discharging mechanism are installed in sequence. The feeding lifting mechanism, ultrasonic cavitation soaking mechanism, brushing mechanism, air-vibration drying mechanism, and detection mechanism are all electrically connected to a control module to automate the leafy vegetable cleaning process. Multiple material holders are hinged to the top of the conical water collection tray so that the conical water collection tray can drive the multiple material holders to achieve feeding, soaking, washing, vibrating, drying, detection, and discharging of the leafy vegetables.

[0009] The annular guide rail has a feeding port in the feeding area and the feeding area, and a soaking port, a washing port, and a drying port in the ultrasonic cavitation soaking area, the brushing area, and the air-vibration drying area, so that after the leafy vegetables are fed, soaked, washed, brushed, and vibrated and dried, the holding rack can move onto the annular guide rail as the conical water collection plate rotates.

[0010] As a preferred embodiment of the above solution, the material holding rack includes a mounting plate formed by three U-shaped plates connected in sequence. Upper material holding rods are fixedly installed at the four upper ends of the inner side of the mounting plate, and lower material holding rods are fixedly installed at the three lower ends, so that three U-shaped vegetable placement troughs are formed on the mounting plate. Each vegetable placement trough consists of two upper material holding rods and one lower material holding rod. The length of the lower material holding rod of the middle vegetable placement trough is greater than the lengths of the other upper and lower material holding rods. This lower material holding rod is designed as a functional rod, so that the end of the functional rod away from the conical water collection tray is placed on a circular track, thereby keeping the material holding rack in a horizontal state.

[0011] More preferably, the feeding lifting mechanism includes a lead screw assembly and a feeding section. The lead screw assembly includes a lifting motor, a motor protective cover, a mounting bracket, a threaded rod, and a slider. The mounting bracket is fixedly mounted on a central column, the motor protective cover is fixedly mounted on the bottom end of the mounting bracket, the lifting motor is fixedly mounted inside the motor protective cover, the output shaft of the lifting motor is fixedly connected to the threaded rod, the lifting motor is electrically connected to a control module, both ends of the threaded rod are rotatably connected to the mounting bracket, the slider is slidably connected to the mounting bracket and threadedly connected to the threaded rod, and the feeding section is fixedly mounted on the slider so that the feeding section moves the material holding frame upwards, causing the material holding frame to move onto the annular guide rail as the conical water collection plate rotates.

[0012] More preferably, the ultrasonic cavitation soaking mechanism includes a screw assembly, a soaking bucket, a lifting door, a soaking water pipe, and a placement rack. The soaking bucket and the soaking water pipe are both fixedly installed on a central column so that the soaking water pipe sprays water into the soaking bucket. The soaking bucket has a drain outlet, and an ultrasonic transducer is fixedly installed on the soaking bucket. The ultrasonic transducer is electrically connected to a control module. The lifting door is slidably installed inside the drain outlet and is fixedly installed on the slider of the screw assembly. The placement rack is fixedly installed on the lifting door and located inside the soaking bucket to support the material holder. This allows the lifting door to lift the material holder and the leafy vegetables after they have been soaked and cleaned in the soaking bucket, and the soaking water to be automatically discharged from the drain outlet.

[0013] More preferably, the brushing mechanism includes a lead screw assembly, a brushing section, multiple water inlet pipes, and a water-driven spinning roller with brush bristles adhered to its outer surface. The multiple water inlet pipes are all fixedly installed on a central column, and the multiple water inlet pipes are supplied with water by a water supply device. The water supply device is electrically connected to a control module. The water-driven spinning roller is rotatably installed on the water inlet pipes, and multiple inclined water spray holes are evenly spaced around the circumference of the water-driven spinning roller.

[0014] Multiple water spray holes constitute a water spray hole group. The portion of the water inlet pipe located inside the water-driven spinning drum has multiple water outlet holes. Multiple water spray hole groups are evenly spaced along the length of the water-driven spinning drum so that the water-driven spinning drum can automatically rotate by spraying water through the water spray holes on the water inlet pipe. The brushing section is fixedly installed on the slider of the screw assembly and located between two water-driven spinning drums so that the material holder can rotate up and down between multiple water-driven spinning drums, thereby placing the leafy vegetables between multiple water-driven spinning drums for brushing.

[0015] More preferably, the air-vibration draining mechanism includes a fan, a cam, and a rotating motor. The cam is rotatably mounted on the central column and located inside the air-drying opening. The rotating motor is fixedly mounted on the central column and is connected to the cam via a transmission. The fan is fixedly mounted on the central column and is located above the cam so that it can dry the leafy vegetables when the cam vibrates the material holding frame. Both the fan and the rotating motor are electrically connected to the control module.

[0016] More preferably, the detection mechanism includes a processing module and multiple cameras. The multiple cameras are all fixedly installed on the central column and are located at the upper and lower ends of the annular guide rail, so as to collect image information from both the upper and lower ends of the leafy vegetables. The processing module is electrically connected to the multiple cameras to process the image information and generate corresponding visual identification information, thereby providing data support for affixing identification codes to the packaging bags of the cleaned leafy vegetables. The control module is electrically connected to the multiple cameras.

[0017] More preferably, the feeding mechanism includes a feeding hopper, on which a plurality of evenly spaced guide wheel sets are fixedly installed, so that the material holding frame rotates downward through the gaps between the plurality of guide wheel sets and drops the leafy vegetables into the feeding hopper through the guide wheel sets.

[0018] A further preferred embodiment is that a water tank is fixedly installed on the frame, and multiple water receiving hoppers are provided around the central column. The multiple water receiving hoppers are all fixedly installed on the central column and are sequentially and fixedly connected to each other. Drain pipes are fixedly installed at the bottom of the multiple water receiving hoppers. The bottom of the conical water collecting plate is rotatably connected to the multiple water receiving hoppers, and the drain pipes are fixedly connected to the water tank so as to drain the water in the conical water collecting plate into the water tank.

[0019] The beneficial effects of this invention are:

[0020] 1. By adopting a control module, power motor, conical water collection tray, material holding rack, ring guide rail, feeding and lifting mechanism, ultrasonic cavitation soaking mechanism, brushing mechanism, air vibration draining mechanism and unloading mechanism, the leafy vegetable washing process can be automated, thereby improving the washing efficiency of leafy vegetables, and ensuring that the washing quality of leafy vegetables remains stable and the washing is more thorough.

[0021] 2. The feeding lifting mechanism, ultrasonic cavitation soaking mechanism, brushing mechanism, air vibration draining mechanism, detection mechanism and unloading mechanism of the present invention are all relatively gentle on leafy vegetables, which reduces the loss of leafy vegetables in the washing process and improves the safety of leafy vegetables.

[0022] 3. The air-vibration drying mechanism can vibrate and air-dry leafy vegetables, thereby fully draining the water from the leafy vegetables and facilitating subsequent testing of the leafy vegetables.

[0023] 4. The feeding area, ultrasonic cavitation soaking area, washing area, air-vibration draining area, testing area and unloading area are arranged around the central column in sequence, which can concentrate the leafy vegetable washing process and thus improve the washing efficiency of leafy vegetables.

[0035] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-10 As shown, a rotary leafy vegetable washing device consists of a frame 1, a central column 2, a power motor 3, and a conical water collection tray 4. The central column 2 and the power motor 3 are fixedly mounted on the frame 1, and the conical water collection tray 4 is rotatably mounted on the frame 1. The central column 2 is located inside the conical water collection tray 4. The power motor 3 is driven and electrically connected to the conical water collection tray 4 and a control module, so that the conical water collection tray 4 rotates relative to the central column 2.

[0037] A ring-shaped guide rail 9 is fixedly installed on the upper end of the central column 2. Around the central column 2, a feeding area, an ultrasonic cavitation soaking area, a brushing area, an air-vibration drying area, a detection area, and a discharging area are arranged in sequence. A feeding lifting mechanism, an ultrasonic cavitation soaking mechanism 300, a brushing mechanism 400, an air-vibration drying mechanism 500, a detection mechanism, and a discharging mechanism 600 are also installed in sequence. The feeding lifting mechanism, ultrasonic cavitation soaking mechanism 300, brushing mechanism 400, air-vibration drying mechanism 500, and detection mechanism are all electrically connected to a control module to automate the leafy vegetable washing process. Multiple material holders 100 are hinged to the top of the conical water collection tray 4, allowing the conical water collection tray 4 to drive the multiple material holders 100 to perform feeding, soaking, washing, vibrating drying, detection, and discharging of the leafy vegetables.

[0038] The annular guide rail 9 has a feeding port 13 in the feeding area and the feeding area, and a soaking port 10, a washing port 11 and a drying port 12 in the ultrasonic cavitation soaking area, the brushing area and the air-vibration drying area, so that after the leafy vegetables are fed, soaked, washed, brushed and vibrated and dried, the material holding rack 100 can move onto the annular guide rail 9 as the conical water collecting plate 4 rotates.

[0039] The material holding rack 100 is composed of an installation plate 101 formed by four upper material holding rods 102, three lower material holding rods 103, and three U-shaped plates connected in sequence. The four upper material holding rods 102 are respectively fixedly installed on the four upper ends of the inner side of the installation plate 101, and the three lower material holding rods 103 are respectively fixedly installed on the three lower ends of the inner side of the installation plate 101, so that three U-shaped vegetable troughs are formed on the installation plate 101. Each vegetable trough is composed of two upper material holding rods 102 and one lower material holding rod 103. The length of the lower material holding rod 103 of the middle vegetable trough is greater than the length of the other upper material holding rods 102 and lower material holding rods 103. The lower material holding rod 103 is set as a functional rod 104, so that the end of the functional rod 104 away from the conical water collection plate 4 is placed on the circular track, thereby keeping the material holding rack 100 in a horizontal state.

[0040] The feeding mechanism 600 consists of a feeding hopper 602 and multiple guide wheel sets 601. Multiple guide wheel sets 601 arranged at even intervals are fixedly installed on the feeding hopper 602 so that the material holding frame 100 can rotate downward through the gaps between the multiple guide wheel sets 601 and drop the leafy vegetables into the feeding hopper 602 through the guide wheel sets 601.

[0041] The control module controls the motor 3 to rotate, causing the conical water collection tray 4 to rotate along with the material holder 100 until the function lever 104 rotates onto the feeding lifting mechanism. The conical water collection tray 4 then stops rotating. The control module then controls the feeding lifting mechanism to move, pushing the material holder 100 upwards until it reaches a horizontal position. Leafy vegetables are then placed in the vegetable trough with the stems facing inwards and the leaves facing outwards. The control module controls the motor 3 to rotate, causing the conical water collection tray 4 to rotate along with the material holder 100 and the leafy vegetables. The end of the function lever 104 away from the conical water collection tray 4 slides on the annular guide rail 9. The material holder 100 then rotates to the ultrasonic cavitation soaking zone, and the control module controls the ultrasonic cavitation soaking. Mechanism 300 soaks and washes the leafy vegetables, then the holding frame 100 rotates the leafy vegetables sequentially to the washing area, the air-vibration drying area, and the inspection area. The control module sequentially controls the washing mechanism 400 to wash the leafy vegetables, the air-vibration drying mechanism 500 to vibrate and air-dry the leafy vegetables, and the inspection mechanism to inspect the leafy vegetables. Then, the holding frame 100 rotates the leafy vegetables to the unloading area. The functional rod 104 passes downward through the feed inlet 13. The upper holding rod 102, the lower holding rod 103, and the functional rod 104 on the holding frame 100 all rotate downward and pass through the gap between the guide wheel assembly 601. The leafy vegetables on the holding frame 100 fall onto the guide wheel assembly 601 and then slide from the guide wheel assembly 601 to the lower hopper 602.

[0042] A packaging mechanism is connected below the feeding hopper 602 to package the leafy vegetables. This packaging mechanism is existing technology and will not be described in detail here. Figure 11As shown, the power motor 3 and the conical water collection tray 4 are connected by a Geneva mechanism 6. The Geneva mechanism 6 includes a Geneva wheel 15 and a dial 14. The Geneva wheel 15 is fixedly mounted on the conical water collection tray 4, and the dial 14 is fixedly mounted on the output shaft of the power motor 3. The movement mechanism of the Geneva mechanism 6 is as follows: the output shaft of the power motor 3 drives the dial 14 to rotate, but the Geneva wheel 15 remains stationary. At this time, the Geneva wheel 15 stops for 20 seconds, and the feeding lifting mechanism, ultrasonic cavitation soaking mechanism 300, brushing mechanism 400, air-vibration drying mechanism 500, detection mechanism, and unloading mechanism 600 work. Then, the dial 14 drives the Geneva wheel 15 to rotate for 10 seconds, so that multiple material holders 100 carry the leafy vegetables on them into the next area. The number of material holders 100 can be 6. The 6 material holders 100 are evenly spaced at the top of the conical water collection tray 4 so that the feeding, soaking, washing, vibrating and drying, detection, and unloading of leafy vegetables can occur in the same time period, improving the cleaning efficiency of leafy vegetables.

[0043] The feeding lifting mechanism consists of a lead screw assembly 200 and a feeding section 8. The lead screw assembly 200 comprises a lifting motor, a motor protective cover 204, a mounting frame 201, a threaded rod 202, and a slider 203. The mounting frame 201 is fixedly mounted on the central column 2, and the motor protective cover 204 is fixedly mounted on the bottom end of the mounting frame 201. The lifting motor is fixedly mounted inside the motor protective cover 204. The output shaft of the lifting motor is fixedly connected to the threaded rod 202, and the lifting motor is electrically connected to the control module. Both ends of the threaded rod 202 are rotatably connected to the mounting frame 201. The slider 203 is slidably connected to the mounting frame 201 and threadedly connected to the threaded rod 202. The feeding section 8 is fixedly mounted on the slider 203 so that the feeding section 8 moves the material holding frame 100 upward, causing the material holding frame 100 to move onto the annular guide rail 9 as the conical water collection plate 4 rotates.

[0044] When the function lever 104 rotates onto the feeding section 8, the control module controls the lifting motor (not shown in the attached diagram) to rotate. The lifting motor rotates the threaded rod 202, and the slider 203 moves upward together with the feeding section 8. The function lever 104 rotates upward until it passes through the material inlet 13 and rotates to a horizontal state. At this time, the material holder 100 is also in a horizontal state.

[0045] The ultrasonic cavitation soaking mechanism 300 consists of a lead screw assembly 200, a soaking tank 301, a lifting door 302, a soaking water pipe, and a placement rack 304. The soaking tank 301 and the soaking water pipe are both fixedly mounted on the central column 2, allowing the soaking water pipe to spray water into the soaking tank 301. The soaking tank 301 has a drain outlet 303, and an ultrasonic transducer is fixedly mounted on it, electrically connected to a control module. The lifting door 302 is slidably mounted inside the drain outlet 303 and is fixedly mounted on the slider 203 of the lead screw assembly 200. The placement rack 304 is fixedly mounted on the lifting door 302 and located inside the soaking tank 301 to support the material holder 100. This allows the lifting door 302 to lift the material holder 100 and the leafy vegetables after soaking and cleaning in the soaking tank 301, automatically draining the soaking water from the drain outlet 303.

[0046] The feed holder 100 rotates with the leafy vegetables into the ultrasonic cavitation soaking zone. The function lever 104 rotates onto the placement rack 304. Then, the control module controls the lifting motor of the ultrasonic cavitation soaking zone to rotate, causing the lifting door 302 to move downwards with the placement rack 304 inside the drain outlet 303. The function lever 104 rotates downwards through the soaking opening 10 until the bottom end of the lifting door 302 abuts against the bottom end of the drain outlet 303, forming a closure of the drain outlet 303. At this time, the leafy vegetables on the feed holder 100 are completely located inside the soaking hopper 301. The control module controls the water supply equipment of the soaking water pipe (not shown in the attached diagram) to supply water, and the soaking water pipe sprays water into the soaking hopper 301 until the water level in the soaking hopper 301 reaches the set water level range. After the vegetables are completely submerged in water, the control module controls the ultrasonic transducer (not shown in the attached diagram) to generate a cavitation effect in the water, which effectively cleans the vegetables. Once the vegetables are cleaned, the ultrasonic transducer stops, and the control module controls the lifting motor to move the lifting door 302 and the placement rack 304 upwards. The soaking water flows from the drain 303 into the conical water collection tray 4. The functional rod 104 rotates upwards with the material holder 100 and the vegetables until the functional rod 104 rotates upwards through the soaking port 10 and reaches a horizontal position. The control module then controls the power motor 3 to rotate the functional rod 104 onto the annular guide rail 9 and rotates the washing area along the annular guide rail 9.

[0047] The scrubbing mechanism 400 consists of a lead screw assembly 200, a scrubbing section 404, multiple water inlet pipes 401, and a water-driven rotating drum 402 with brush bristles adhered to its outer surface. The multiple water inlet pipes 401 are all fixedly mounted on the central column 2. Water is supplied to the multiple water inlet pipes 401 by a water supply device, which is electrically connected to the control module. The water-driven rotating drum 402 is rotatably mounted on the water inlet pipes 401, and multiple inclined water spray holes 403 are evenly spaced around the circumference of the water-driven rotating drum 402.

[0048] Multiple water spray holes 403 constitute a water spray hole group. The portion of the water inlet pipe 401 located inside the water-driven spinning drum 402 has multiple water outlet holes. Multiple water spray hole groups are evenly spaced along the length of the water-driven spinning drum 402 to enable the water-driven spinning drum 402 to automatically rotate by spraying water through the water spray holes 403 on the water inlet pipe 401. The brushing section 404 is fixedly installed on the slider 203 of the lead screw assembly 200 and located between the two water-driven spinning drums 402, so that the material holder 100 can rotate up and down between the multiple water-driven spinning drums 402, thereby placing the leafy vegetables between the multiple water-driven spinning drums 402 for brushing.

[0049] The function lever 104 rotates onto the brushing section 404. The control module controls the lifting motor of the brushing area to rotate, causing the brushing section 404 to move downward. The function lever 104 rotates downward through the brushing port 11. The brushing section 404 and the material holder 100 both pass through the gap between the water-driven spinning drum 402, allowing the leafy vegetables on the material holder 100 to be placed on the water-driven spinning drum 402. Then, the control module controls the water supply equipment to supply water to the water inlet pipe 401. Water enters the water-driven spinning drum 402 from the water outlet of the water inlet pipe 401 (not shown in the attached figure) and then sprays out from the spray nozzle 403, driving the water-driven spinning drum 402 and the leafy vegetables to rotate. The water sprayed from the spray nozzle 403 and the brush bristles (not shown in the attached figure) form a brushing action on the leafy vegetables. After the washing is complete, the water-driven self-rotating drum 402 stops rotating, the washing section 404 moves upward, and the material holder 100 rotates upward with the leafy vegetables until the functional rod 104 passes through the washing port 11 and rotates to a horizontal position. The water supply equipment for the soaking water pipe and the water inlet pipe 401 can be the same. The water supply equipment is existing technology and will not be described in detail here.

[0050] The air-vibration drying mechanism 500 consists of a fan 501, a cam 503, and a rotary motor 502. The cam 503 is rotatably mounted on the central column 2 and located inside the drying inlet 12. The rotary motor 502 is fixedly mounted on the central column 2 and is driven by the cam 503. The fan 501 is fixedly mounted on the central column 2 and is located above the cam 503 so that it can dry the leafy vegetables when the cam 503 vibrates the material holder 100. Both the fan 501 and the rotary motor 502 are electrically connected to the control module.

[0051] Functional lever 104 rotates from the annular guide rail 9 onto cam 503. The control module controls the rotation of motor 502 and the blowing of fan 501. Fan 501 concentrates the airflow towards the ends of the leafy vegetables to dry them and peel off the water film on the leaf surface. Cam 503 pushes functional lever 104 to rotate up and down, creating high-frequency micro-amplitude oscillation of the holding frame 100. This mechanical vibration and blowing of fan 501 quickly drain the surface water of the leafy vegetables and shake off loosely attached yellow leaves. Then cam 503 stops rotating, and functional lever 104 and holding frame 100 are in a horizontal state. The control module controls the rotation of motor 3 to make functional lever 104 continue to rotate onto the annular guide rail 9 and move towards the detection area. Fan 501 can be replaced by an air pump to dry the leafy vegetables.

[0052] The detection mechanism consists of a processing module and multiple cameras. The cameras are fixedly mounted on the central column 2, positioned at the upper and lower ends of the annular guide rail 9, to collect image information from both ends of the leafy greens. The processing module is electrically connected to the cameras to process the image information and generate corresponding visual identification information, thus providing data support for affixing identification codes to the packaging bags of the cleaned leafy greens. The control module is also electrically connected to the cameras.

[0053] The material holder 100 rotates to the detection area, and the control module (not shown in the attached figure) controls the camera (not shown in the attached figure) to take pictures of the leafy vegetables from both the top and bottom, thereby realizing the acquisition of image information of the leafy vegetables. Then, the processing module (not shown in the attached figure) processes these image information and generates corresponding visual identification information.

[0054] A water tank 5 is fixedly installed on the frame 1. Multiple water collection hoppers 7 are arranged around the central column 2, and each water collection hopper 7 is fixedly installed on the central column 2 and sequentially connected to each other. Drain pipes are fixedly installed at the bottom of each water collection hopper 7, and the bottom of a conical water collection tray 4 is rotatably connected to the multiple water collection hoppers 7. The drain pipes are fixedly connected to the water tank 5 so that water from the conical water collection tray 4 can be drained into the water tank 5.

[0055] Water from the ultrasonic cavitation soaking zone, the brushing zone, and the air-vibration drying zone all flow into the water tank 5 through the water receiving hopper 7 and the drain pipe (not shown in the attached diagram). The water tank 5 is connected to a filtration system, which is connected to the water supply equipment so that the water in the water tank 5 can be filtered and reused. The water in the water tank 5 can be drained and replaced with new water periodically.

[0056] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
