Description

Technical Field

[0001] This invention belongs to the field of vortex vegetable washing technology, specifically designing an automatic vegetable washing production line. Background Technology

[0002] Freshly picked fruits and vegetables usually have some pesticide residue and insect remains on their surface. Therefore, washing vegetables is a crucial step before processing. To more thoroughly remove residues from the surface of fruits and vegetables, a vortex washing method is often used.

[0003] Currently, the vortex vegetable washer with announcement number CN207707807U and vortex vibration vegetable washers including this vortex vegetable washer include a washing tank. The side wall of the washing tank is equipped with a vortex mechanism communicating with the washing tank. One end of the washing tank is the vegetable inlet, and the other end is the vegetable outlet. A rinsing mechanism is set at the vegetable inlet of the washing tank. The rinsing mechanism includes a main rinsing pipe extending to near the vortex mechanism. Several rinsing branch pipes communicating with the washing tank are opened on the main rinsing pipe. The end of the rinsing water pipe is set near the vortex water outlet, which cooperates with the vortex water outlet to push vegetables in the dead corners towards the outlet.

[0004] However, some problems exist: 1. The device does not perform fixed-weight packaging after discharging the material; if all the material is piled together, it is prone to mold. 2. The device does not dehydrate the vegetables, which will reduce their shelf life and affect packaging and transportation. Summary of the Invention

[0005] This invention provides an automatic vegetable washing production line to solve the problem of fixed-weight packaging after washing vegetables and reduce the probability of mold growth.

[0006] This solution provides an automatic vegetable washing production line, including: a vortex device for vortex washing vegetables; a water pump connected to the vortex device; a removal device for removing impurities from vegetables, the vortex device and the removal device being connected in sequence; a controller electrically connected to the water pump; and a weighing device comprising: a base for fixing the weighing device; a control panel for setting a predetermined weight, the control panel being fixedly connected to the base; a rotating motor fixedly connected to the base and electrically connected to the controller; a rotating shaft fixedly connected to the shaft of the rotating motor; multiple weighing plates fixedly connected to the rotating shaft, arranged circumferentially around the rotating shaft, used for measuring weight; and a vegetable basket placed on the weighing plate, the vegetable basket cooperating with the removal device.

[0007] The principle of this solution is as follows: The operator places the vegetables into the vortex device for vortex washing. The water pump is started, adding a high-speed water flow into the vortex device, causing the vegetables to tumble continuously in the spiral water flow. This strong water flow effectively removes dirt, dust, insect residue, and some pesticide residue from the surface of the vegetables. The vegetables then move to a cleaning device, which removes moisture and adhering dirt. After cleaning, the vegetables are placed in a basket for weighing. When the basket reaches the set weight, a motor is started, controlling the rotation of the rotating shaft. The rotating shaft drives the weighing plate to rotate, which in turn drives the basket to rotate, aligning the next empty basket with the discharge port of the cleaning device. This process is repeated to ensure equal weight loading.

[0008] The beneficial effects of this solution are: 1. The high-speed water flow generated by the vortex continuously washes the surface of the vegetables, resulting in a more thorough cleaning effect compared to manual washing or ordinary water rinsing. 2. The treated vegetables are then packed in equal-weight containers to prevent them from piling up and increasing the probability of mold growth.

[0009] Furthermore, the vortex device includes a primary vortex device and a secondary vortex device, and the impurity removal device includes a primary impurity removal device and a secondary impurity removal device. The primary vortex device, the primary impurity removal device, the secondary vortex device, the secondary impurity removal device, and the weighing device are connected sequentially. The two-stage device has two independent cleaning chambers and impurity removal devices, each designed for different cleaning needs. The primary stage focuses on initial decontamination and sediment separation, while subsequent stages perform more detailed cleaning and disinfection. This tiered cleaning method helps to gradually remove different types of contaminants, improving overall cleanliness.

[0010] Furthermore, it also includes a pretreatment device, which comprises a feeding trough, a rinsing pipe, a water curtain box, and a pre-washing pipe. The feeding trough is connected to the primary vortex device, and the feeding trough is connected to the water pump through the rinsing pipe. The water curtain box cooperates with the feeding trough, and the water curtain box is connected to the water pump through the pre-washing pipe. The controller starts the water pump, causing water to flow out from the pre-washing pipe and the rinsing pipe respectively. The water flow from the rinsing pipe rushes into the feeding trough from the bottom up. The operator puts the vegetables into the feeding trough, and the vegetables move towards the primary vortex device under the water flow from the rinsing pipe. At the same time, the water flow from the pre-washing pipe flows out from the water curtain box, forming a water curtain located between the feeding trough and the primary vortex device. The vegetables pass through the water curtain, and large particles of impurities on the vegetables are carried away.

[0011] Pre-rinsing quickly removes most visible dirt from the surface of vegetables, such as soil, gravel, fallen leaves, and insects. These larger particles can easily cause wear and tear on cleaning equipment during subsequent deep cleaning or spread in the cleaning water, affecting the overall cleaning effect. Pre-rinsing effectively reduces the impact of these impurities on subsequent cleaning processes. Pre-rinsing typically uses lower water pressure and less water volume, making it more water-efficient compared to the water required for the vortex cleaning stage. By removing most visible dirt through pre-rinsing, unnecessary waste is avoided.

[0012] Furthermore, the vortex device includes vortex tubes, vortex channels, and adjusting rods for regulating water flow velocity. Multiple vortex tubes are provided, and each tube is helical. One end of each vortex tube is connected to a water pump, and the other end is connected to the vortex channel. The adjusting rod is rotatably connected to the vortex tube. Vortex tubes are typically designed in a helical shape, with their internal channels forming a continuous spiral. This helical structure guides the fluid along a spiral path, generating rotational motion, which is the basis for forming vortices. The adjusting rod can regulate the flow velocity within the vortex tubes, thus affecting the overall cleaning time of the device. Slowing down the flow rate when dealing with a large quantity of vegetables and increasing it when dealing with a small quantity improves cleaning efficiency.

[0013] The impurity removal device includes a cover plate and a frame. The frame is rotatably connected to the cover plate. The frame is equipped with a conveyor belt and a drainage plate. The conveyor belt has a screen belt. A pressure bar for stretching the screen belt is rotatably mounted on the frame of the conveyor belt. The pressure bar is slidably connected to the screen belt. The conveyor belt cooperates with the drainage plate.

[0014] The vegetables arrive at the conveyor belt of the impurity removal device, which transports them to the weighing device. During transport, because the belt is a screen, moisture and small particles from the vegetables pass through the screen and fall onto a drainage plate. The drainage plate carries the water and particles out for recycling or as wastewater. Some impurities may adhere to the screen. When the screen moves under the conveyor belt, a pressure bar stretches the screen, enlarging the sieve openings and removing the particles.

[0015] Furthermore, it also includes an automatic dehydration device, which comprises a frame for fixing various devices; a turntable rotatably connected to the frame; a rotary motor fixedly connected to the frame, with its shaft coaxially fixedly connected to the turntable, and electrically connected to a controller; dehydration cylinders rotatably connected to the turntable, with multiple cylinders arranged circumferentially around the turntable; and multiple dehydration motors fixedly connected to the turntable. The shaft of the water motor is connected to the dewatering cylinder via a belt, and the dewatering motor is electrically connected to the controller; the bearing frame is rotatably connected to the dewatering cylinder; the feed hopper is fixedly connected to the frame and cooperates with the dewatering cylinder; the bottom plate is rotatably connected to the dewatering cylinder via a rotating shaft; the rotating mechanism includes: a rotating shaft with a torque spring; a rotating ring fixedly connected to the rotating shaft; and an automatic feeding mechanism for rotating the rotating ring, which cooperates with the rotating ring.

[0016] The operator pours vegetables into the feeding hopper. After a set time, the feeding stops. At this point, the controller controls the rotary motor to rotate, moving the dehydration drum to the second station. The dehydration motor in the second station rotates, driving the belt to rotate, which in turn rotates the dehydration drum for dehydration. Simultaneously, the feeding hopper in the first station begins feeding. After another set time, the feeding stops, and the controller controls the rotary motor to rotate, moving the dehydration drum to the third station. The dehydration drum in the third station rotates faster for further dehydration, while the feeding hopper in the first station begins feeding. After yet another set time, the controller controls the rotary motor to rotate, moving the dehydration drum to the fourth station. The dehydration drum in the fourth station rotates slower. When the dehydration drum reaches the fourth station, the rotating ring at the shaft intermittently contacts the automatic feeding mechanism. Each contact causes the automatic feeding mechanism to rotate the ring, opening the bottom plate to release the vegetables. This mechanism utilizes the fact that when the dehydration drum rotates to the fourth station, it contacts the automatic feeding mechanism, causing the bottom plate to rotate and open, thus achieving automatic feeding. The structure is simple. Because the bottom plate of this mechanism opens intermittently and closes automatically due to a torque spring, the repeated opening and closing generates impact vibrations on the dehydration drum, which can shake off the vegetables adhering to the drum wall.

[0017] Furthermore, the automatic feeding mechanism includes a guide block, a connecting rod, and a fixing plate. The fixing plate cooperates with the frame. One end of the connecting rod is fixedly connected to the fixing plate, and the other end is fixedly connected to the guide block. The surface of the guide block is frosted, and the frosted surface of the guide block cooperates with the rotating ring.

[0018] When the dehydration drum reaches the fourth station and rotates, the rotating ring contacts the guide block. Due to the high surface friction of the guide block, the rotating ring rotates, driving the rotating shaft to rotate. The rotating shaft then drives the bottom plate to rotate, causing the bottom plate to open and allowing the vegetables to fall out. When the rotating ring moves away from the guide block, the bottom plate returns to its original position under the action of the torque spring, simultaneously impacting and vibrating the dehydration drum. This mechanism achieves automatic feeding through a mechanical structure and possesses stability.

[0019] Furthermore, it also includes a buffer mechanism, which comprises a slide cylinder. The piston rod of the slide cylinder is fixedly connected to a fixed plate, and the cylinder body of the slide cylinder is fixedly connected to a frame. The guide block is a right-angled triangle with a frosted surface on its inclined plane. When the guide block contacts and rubs against the rotating ring, it is easy for the ring to impact and jam. This mechanism designs the guide block as a right-angled triangle, making it easier for the rotating ring to slide onto the guide block. However, this also subjects the guide block to an upward force, which could easily damage it. This mechanism uses the fixed connection between the guide block and the piston rod of the slide rail to give the guide block a certain degree of buffering, reducing the damage caused by the force.

[0020] Furthermore, it also includes a jetting mechanism, which includes a venting plate and a return spring. The slide cylinder is a pneumatic cylinder, which includes a cylinder body, a piston, and a pressure rod. The cylinder body is fixedly connected to the frame, and the cylinder body is provided with an air inlet. The air inlet is provided with a one-way valve. The piston is slidably connected to the cylinder body. One end of the pressure rod is fixedly connected to the piston, and the other end is fixedly connected to a fixed plate. One end of the return spring is fixedly connected to the piston, and the other end is fixedly connected to the cylinder body. The venting plate is fixedly connected to the bearing bracket, and the venting plate is provided with a nozzle. The nozzle is aligned with the dehydration cylinder, and the cylinder body is connected to the venting plate.

[0021] When the dehydration cylinder reaches the fourth station and rotates, the rotating ring contacts the guide block. The rotating ring then lifts the guide block, causing it to move upwards. This movement drives the connecting rod upwards, which in turn moves the fixed plate upwards. The fixed plate then moves the pressure rod upwards, which in turn moves the piston upwards, drawing air into the cylinder through the inlet. When the rotating ring moves away from the guide block, the guide block returns under the action of the return spring, and the piston moves downwards, forcing the air into the venting plate. The venting plate then sprays air through nozzles onto the dehydration cylinder. This high-pressure gas sprays the vegetables adhering to the cylinder wall off. This mechanism uses the vertical displacement of the guide block as a buffer to generate high-pressure gas for spraying onto the dehydration cylinder, effectively preventing vegetables from adhering to the cylinder wall. Compared to existing methods that use an air pump for spraying, this solution saves energy by converting the previously buffered vertical movement into the power of an air pump, thus reducing costs.

[0035] The basics are as follows: Figure 1 , Figure 7 As shown:

[0036] This solution provides an automated vegetable washing production line, including an automatic dehydration device, a pretreatment device 100, a primary vortex device 200, a primary impurity removal device 300, a secondary vortex device 400, a secondary impurity removal device 500, and a weighing device 600. The pretreatment device 100 is used to initially clean large particles of impurities from the vegetables. The primary vortex device 200 is used for initial decontamination, with a higher vortex speed compared to the primary vortex device 200. The secondary vortex device 400 focuses on rinsing and disinfection, with a relatively lower vortex speed. The primary impurity removal devices 300 and 500 are used to initially separate impurities and moisture from the vegetables. The automatic dehydration device is used to further separate moisture from the vegetables, and the weighing device 600 is used for precise measurement of a fixed weight. The pretreatment device 100, primary vortex device 200, primary impurity removal device 300, secondary vortex device 400, secondary impurity removal device 500, automatic dehydration device, and weighing device 600 are connected sequentially.

[0037] As attached Figure 2 As shown:

[0038] The primary vortex device 200 and the secondary vortex device 400 have the same structure, differing only in the controlled vortex velocity and propulsion speed. The primary vortex device 200 includes vortex tubes 201, vortex channels 202, and adjusting rods 203 for regulating water flow velocity. Multiple vortex tubes 201 are provided, and each vortex tube 201 is helical. One end of each vortex tube 201 is connected to a water pump 204, and the other end is connected to the vortex channel 202. The adjusting rod 203 is rotatably connected to the vortex tubes 201. The vortex tubes 201 are typically designed in a helical shape, with their internal channels forming a continuous spiral. This helical structure guides the fluid along a spiral path, generating rotational motion, which is the basis for vortex formation. The adjusting rod 203 regulates the flow velocity within the vortex tubes 201, thus affecting the overall cleaning time of the device. Slowing down the flow velocity when dealing with large quantities of vegetables and increasing it when dealing with small quantities improves cleaning efficiency. The primary vortex device 200 also includes steps 205 for easy inspection by staff.

[0039] As attached Figure 3 As shown:

[0040] The pretreatment device 100 includes a feeding trough 101, a rinsing pipe 102, a water curtain box 103, and a pre-washing pipe 104. The feeding trough 101 is connected to the first-stage vortex device 200. The feeding trough 101 is connected to the water pump 204 through the rinsing pipe 102. The water curtain box 103 is located above the feeding trough 101. When water enters the water curtain box 103 through the pre-washing pipe 104, it will form a water curtain downwards. When vegetables enter from the feeding trough 101, they will pass through the water curtain, achieving the pre-washing effect. The water curtain box 103 is connected to the water pump 204 through the pre-washing pipe 104.

[0041] As attached Figure 4 As shown:

[0042] The impurity removal device includes a cover plate 301 and a frame 305. The frame 305 is rotatably connected to the cover plate 301. The frame 305 is equipped with a conveyor belt 302 and a drainage plate 304. The belt of the conveyor belt 302 is a screen belt 303. A pressure bar 306 for stretching the screen belt 303 is rotatably provided on the frame of the conveyor belt 302. The pressure bar 306 is slidably connected to the screen belt 303. The conveyor belt 302 is above the drainage plate 304, so that when the vegetables are on the conveyor belt 302, water and small particles will fall through the screen belt 303 of the conveyor belt 302 and fall into the drainage plate 304.

[0043] As attached Figure 5 , Figure 6 As shown:

[0044] The weighing device 600 includes a base 604 for fixing the weighing device 600; a control panel 601 for setting a predetermined weight, the control panel 601 being fixedly connected to the base 604; a rotating motor 606 fixedly connected to the base 604 and electrically connected to a controller; a rotating shaft 605 fixedly connected to the shaft of the rotating motor 606; a weighing plate 603 fixedly connected to the rotating shaft 605, and multiple weighing plates 603 arranged in a circumferential pattern around the rotating shaft 605, used for measuring weight; and a vegetable basket 602 placed on the weighing plate 603.

[0045] As attached Figure 7 , Figure 8 As shown:

[0046] The automatic dewatering device includes a frame 1, a turntable 32, a rotary motor 30, a dewatering cylinder 5, a dewatering motor 10, a bearing frame 9, a base plate, a rotating mechanism, an automatic feeding mechanism 12, a feeding hopper 2, a cleaning mechanism, a top cover 3, and a side cover 4. The frame 1 is elliptical in shape with a hollow center. The turntable 32 is parallel to the ground and rotatably connected to the frame 1. The rotary motor 30 is fixedly connected to the frame 1, and the shaft of the rotary motor 30 is coaxially fixedly connected to the turntable 32. The dehydration cylinders 5 are rotatably connected to the turntable 32. There are four dehydration cylinders 5, which are distributed circumferentially around the turntable 32, with one dehydration cylinder 5 every 90 degrees, for a total of four stations. The first station is used for feeding, and the rotary motor 30 rotates after a certain time. The second station is used for medium-speed dehydration. Due to excessive moisture, excessive rotation speed can easily burn out the motor. The third station is used for high-speed dehydration, which further dehydrates and reduces the moisture content of the vegetables. The fourth station is the unloading station, used for unloading vegetables. The frame 1 has a loading port 31, which is aligned with the fourth station. The vegetables are unloaded into the vegetable basket of the weighing device 600 through the loading port 31. The bottom of the frame 1 has a fixed frame 6, which is a tripod used to stabilize the entire machine body. Multiple dehydration motors 10 are provided, and each motor 10 is fixedly connected to a turntable 32. The shaft of each motor 10 is connected to the dehydration cylinder 5 via a belt 11. A bearing bracket 9 is rotatably connected to the dehydration cylinder 5. A feeding hopper 2 is fixedly connected to a frame 1, located above the dehydration cylinder 5 and above the first workstation. The feeding hopper 2 is connected to the conveyor belt 302 of the secondary impurity removal device 500, allowing vegetables to enter the dehydration cylinder 5 at the first workstation through the feeding hopper 2. Three side covers 4 are provided, rotatably connected to the frame 1, and arranged in a circle around the frame 1. Each side cover 4 has a handle 13, which facilitates the operator's opening and closing of the side covers 4. A top cover 3 is rotatably connected to the frame 1. The top cover 3 and side covers 4 protect the internal motors and dehydration cylinder 5 from ash ingress, and also protect the operator from accidental contact with dangerous parts that could cause injury. The top cover 3 and side covers 4 can also be opened and closed for easy maintenance by the operator.

[0047] The cleaning mechanism includes a water pump 7 and a water inlet tank. The water pump 7 is located above the dehydration drum 5 and is fixedly connected to the frame 1. The water inlet tank is located at the fourth station and has an inlet 8 and an outlet. The water pump 7 is connected to the water inlet tank through the inlet 8, and the outlet is located above the dehydration drum 5 at the fourth station. The controller is electrically connected to all electrical components.

[0048] As attached Figure 11 As shown:

[0049] The base plate includes a left base plate 27 and a right base plate 28. The rotating mechanism includes a rotating shaft 25 and a rotating ring 15. A torque spring 26 is provided at the rotating shaft 25, and there are two rotating shafts 25, torque springs 26, and rotating rings 15. A mounting bracket 29 is provided in the middle of the bottom of the dewatering cylinder 5. The two rotating rings 15 are fixedly connected to the two rotating shafts 25 respectively. Both rotating shafts 25 are rotatably connected to the mounting bracket 29. The left base plate 27 and the right base plate 28 are fixedly connected to their respective rotating shafts 25. The left base plate 27 and the right base plate 28 are rotatably connected to the dewatering cylinder 5 through their respective rotating shafts 25. Since the rotation speed of the fourth station is slow, the two rotating mechanisms can increase the contact frequency between the rotating ring 15 and the guide block 14, increase the bottom plate flipping frequency, and thus improve the material feeding efficiency.

[0050] like Figure 2 , Figure 3 , Figure 4 As shown:

[0051] The automatic feeding mechanism 12 includes a guide block 14, a connecting rod 16, and a fixing plate 19. One end of the connecting rod 16 is fixedly connected to the fixing plate 19, and the other end is fixedly connected to the guide block 14. The guide block 14 is a right-angled triangle with a frosted surface on its inclined surface. When the dewatering cylinder 5 rotates, the rotating ring 15 also rotates. At this time, the rotating ring 15 contacts the frosted surface of the guide block 14. Since the guide block 14 is a right-angled triangle, the rotating ring 15 provides an upward force to the guide block 14, while increasing the friction between the two. When the rotating ring 15 moves away from the guide block 14, the bottom plate returns to its original position under the action of the torque spring 26, and simultaneously impacts and vibrates the dewatering cylinder 5. The buffer mechanism includes a slide cylinder. The piston 24 rod of the slide cylinder is fixedly connected to the fixing plate 19, and the cylinder body of the slide cylinder is fixedly connected to the frame 1. Since the guide block 14 is squeezed by the rotating ring 15, it is easy to be damaged if there is no buffer. When the guide block 14 comes into contact with the rotating ring 15, it is easy to hit the guide block 14 and get stuck. This mechanism designs the guide block 14 as a right triangle, which makes it easier for the rotating ring 15 to slide onto the guide block 14. However, this also makes the guide block 14 subject to an upward force, which can easily damage the guide block 14. This mechanism fixes the guide block 14 to the piston 24 rod of the slide rail, so that the guide block 14 has a certain buffering capacity and reduces the damage caused by the force.

[0052] As attached Figure 8 , Figure 9 , Figure 10 As shown:

[0053] The automatic feeding mechanism 12 includes a guide block 14, a connecting rod 16, and a fixing plate 19. One end of the connecting rod 16 is fixedly connected to the fixing plate 19, and the other end is fixedly connected to the guide block 14. The guide block 14 is a right-angled triangle with a frosted surface on its inclined surface. When the dewatering cylinder 5 rotates, the rotating ring 15 also rotates. At this time, the rotating ring 15 contacts the frosted surface of the guide block 14. Since the guide block 14 is a right-angled triangle, the rotating ring 15 provides an upward force to the guide block 14, while increasing the friction between the two. When the rotating ring 15 moves away from the guide block 14, the bottom plate returns to its original position under the action of the torque spring 26, and simultaneously impacts and vibrates the dewatering cylinder 5. The buffer mechanism includes a slide cylinder. The piston 24 rod of the slide cylinder is fixedly connected to the fixing plate 19, and the cylinder body of the slide cylinder is fixedly connected to the frame 1. Since the guide block 14 is squeezed by the rotating ring 15, it is easy to be damaged if there is no buffer. When the guide block 14 comes into contact with the rotating ring 15, it is easy to hit the guide block 14 and get stuck. This mechanism designs the guide block 14 as a right triangle, which makes it easier for the rotating ring 15 to slide onto the guide block 14. However, this also makes the guide block 14 subject to an upward force, which can easily damage the guide block 14. This mechanism fixes the guide block 14 to the piston 24 rod of the slide rail, so that the guide block 14 has a certain buffering capacity and reduces the damage caused by the force.

[0054] As attached Figure 1-11 As shown:

[0055] The principle of this solution is as follows: the operator puts the vegetables into the feeding trough 101, the controller starts the water pump 204, so that the water flows out from the pre-wash pipe 104 and the rinsing pipe 102 respectively. The water flow from the rinsing pipe 102 rushes into the feeding trough 101 from the bottom up. The operator puts the vegetables into the feeding trough 101, and the vegetables will move towards the first-stage vortex device 200 under the water flow from the rinsing pipe 102. At the same time, the water flow from the pre-wash pipe 104 flows out from the water curtain box 103 to form a water curtain, which is located between the feeding trough 101 and the first-stage vortex device 200. The vegetables pass through the water curtain, and the large particles of impurities on the vegetables are carried away.

[0056] Then the vegetables will come to the first-stage vortex device 200 for preliminary vortex washing. The vortex tube 201 inside the first-stage vortex device 200 enters the water flow, causing the vegetables to tumble continuously in the spiral water flow. This strong water flow force can effectively remove dirt, dust, insect residue, and some pesticide residues from the surface of the vegetables.

[0057] The vegetables then arrive at the primary impurity removal device 300, where they are placed on the conveyor belt 302. The conveyor belt 302 transports the vegetables to the automatic dehydration device. During transport, because the belt is a screen belt 303, moisture and small particles from the vegetables fall through the screen belt 303 onto the drain plate 304. The drain plate 304 carries the water and particles out for recycling or as wastewater disposal. Some impurities may adhere to the screen belt 303. When the screen belt 303 moves below the conveyor belt 302, the pressure rod 306 stretches the screen belt 303, enlarging the screen openings and removing the particles. The impurity removal device removes moisture and adhered dirt.

[0058] After the impurity removal is completed, the vegetables will enter the secondary vortex device 400 and the secondary impurity removal device 500 for secondary cleaning and impurity removal. Then, the vegetables in the secondary impurity removal device 500 will fall from the conveyor belt 302 to the automatic dehydration device.

[0059] Vegetables are poured into hopper 2. After a set time, the feeding stops. At this time, the controller controls the rotary motor 30 to rotate, causing the dehydration cylinder 5 to move to the second station. The dehydration motor 10 of the dehydration cylinder 5 in the second station rotates, driving the belt 11 to rotate. The belt 11 drives the dehydration cylinder 5 to rotate, performing dehydration. At the same time, the feeding hopper 2 in the first station begins to feed. After the set time is reached, the feeding stops, and the controller controls the rotary motor 30 to rotate, causing the dehydration cylinder 5 to move to the third station. The dehydration cylinder 5 in the third station rotates at a higher speed, further dehydrating, while the feeding hopper 2 in the first station begins to feed. Upon reaching the set time, the controller controls the rotary motor 30 to rotate, causing the dehydration cylinder 5 to move to the fourth station. At the fourth station, the rotation speed of the dehydration cylinder 5 decreases. When the dehydration cylinder 5 reaches the fourth station, due to its rotation, the rotating ring 15 at the rotating shaft 25 intermittently contacts the automatic feeding mechanism 12. Each contact causes the rotating ring 15 to contact the guide block 14. Because the guide block 14 has high surface friction and is a right-angled triangle, the rotating ring 15 can more easily slide onto it. Simultaneously, the guide block 14 provides a downward pressure, increasing friction. The rotating ring 15 drives the rotating shaft 25 to rotate, which in turn drives the bottom plate to rotate, causing the bottom plate to open and allowing the vegetables to fall into the basket. When the rotating ring 15 moves away from the guide block 14, the bottom plate returns to its original position under the action of the torque spring 26, simultaneously impacting and vibrating the dehydration cylinder 5 to shake off any adhering vegetables.

[0060] Once the vegetables are placed in the basket, they are weighed. When the vegetables in the basket reach the set weight, the motor starts and controls the rotating shaft to rotate. The rotating shaft drives the weighing plate to rotate, and the weighing plate drives the basket to rotate, so that the next empty basket is aligned with the discharge port of the impurity removal device. This process is repeated to ensure equal weight loading.

[0061] The beneficial effects of this solution are as follows: 1. The high-speed water flow generated by the vortex continuously washes the surface of vegetables, resulting in a more thorough cleaning effect compared to manual washing or ordinary water rinsing. 2. The treated vegetables are reloaded to prevent accumulation and increase the probability of mold growth. 3. Pre-rinsing can quickly remove most visible dirt from the surface of vegetables, such as soil, gravel, fallen leaves, and insects. These larger particles can easily cause wear and tear on the cleaning equipment or spread in the cleaning water during subsequent deep cleaning, affecting the overall cleaning effect. Pre-rinsing can effectively reduce the impact of these impurities on the subsequent cleaning process. Pre-rinsing usually uses lower water pressure and less water volume, making it more water-efficient than the water volume required for the vortex cleaning stage. Removing most visible dirt through pre-rinsing avoids unnecessary waste. 4. When the dewatering cylinder 5 rotates to the fourth station, it touches the guide block 14, causing the base plate to rotate and open, achieving automatic unloading. The structure is simple. 5. The base plate of this mechanism opens intermittently and closes automatically due to the torque spring 26. This reciprocating opening and closing causes impact vibrations to the dehydration cylinder 5, which can shake off the vegetables adhering to the cylinder wall. 6. The buffer mechanism can increase the friction by utilizing the weight of the guide block 14 itself, and slowly release the pressure through the slide cylinder to prevent damage to the guide block 14.

[0062] As attached Figure 12 As shown:

[0063] Example 2

[0064] The automatic dehydration device adds an air jet mechanism, and the slide cylinder uses cylinder 18; otherwise, it is the same as in Example 1.

[0065] The jetting mechanism includes a vent plate 21 and a return spring 23. The cylinder 18 includes a cylinder body, a piston 24 and a pressure rod 17. The cylinder body is fixedly connected to the frame 1. The cylinder body is provided with an air inlet and a one-way valve. The piston 24 is slidably connected to the cylinder body. One end of the pressure rod 17 is fixedly connected to the piston 24 and the other end is fixedly connected to the fixed plate 19. One end of the return spring 23 is fixedly connected to the piston 24 and the other end is fixedly connected to the cylinder body. The vent plate 21 is fixedly connected to the bearing bracket 9. The vent plate 21 is provided with a nozzle 20. The nozzle 20 is aligned with the dehydration cylinder 5. The cylinder body and the vent plate 21 are connected through an air pipe 22.

[0066] When the dehydration cylinder 5 rotates to the fourth station, the rotating ring 15 contacts the guide block 14. The rotating ring 15 then lifts the guide block 14, causing it to move upwards. This movement drives the connecting rod 16 upwards, which in turn moves the fixing plate 19 upwards. The fixing plate 19 then moves the pressure rod 17 upwards, which in turn moves the piston 24 upwards, drawing air into the cylinder 18 through the air inlet. When the rotating ring 15 moves away from the guide block 14, the guide block 14 returns under the action of the return spring 23, and the piston 24 moves downwards, forcing the air into the ventilation plate 21. The ventilation plate 21 then sprays air through the nozzle 20 onto the dehydration cylinder 5. The high-pressure gas sprays the vegetables adhering to the cylinder wall off. This mechanism uses the up-and-down displacement of the guide block 14 as power to produce high-pressure gas that sprays air onto the dehydration cylinder 5, effectively preventing vegetables from adhering to the cylinder wall. Compared to existing methods that use air pumps for jet propulsion, this solution saves energy by converting the previously buffered up-and-down movement into the power of an air pump, thus reducing costs.
