Technical Field

[0001] This invention relates to the field of fruit and vegetable processing technology, and in particular to a pesticide residue removal device for fruit and vegetable processing. Background Technology

[0002] Freshly picked fruits and vegetables usually have dirt, pesticide residues, fertilizer residues, or other stains on their surface. In order to make the fruits and vegetables have a good appearance when sold, they usually need to be pre-washed, which requires the use of corresponding fruit and vegetable cleaning equipment.

[0003] A search revealed that Chinese patent application number 201710492214.9 discloses a device for removing pesticide residues during fruit and vegetable processing. The device includes two sets of parallel mounting brackets connected by a movable rod. A movable block is movably connected to the top of the movable rod. A connecting rod penetrating the movable block and the movable rod is connected to the bottom power output end of a cylinder. A stirring shaft is connected to the top power output end of a drive motor. A vibrating steel plate is installed at the bottom of the inner cavity of the ultrasonic cleaning tank.

[0004] The existing technology has the following shortcomings: existing devices cannot achieve orderly feeding and discharging of fruits and vegetables when cleaning and removing pesticide residues. It is not easy to improve the cleaning effect when feeding and cleaning large quantities or concentrated fruits and vegetables. In addition, there may be impurities such as branches, leaves and soil in the fruits, and it is inconvenient to remove these impurities. Excessive impurities are easy to accumulate inside the device, causing blockage, increasing the time required for subsequent cleaning, and reducing the continuous cleaning efficiency of the device for fruits and vegetables. Therefore, the present invention proposes a pesticide residue removal device for fruit and vegetable processing. Summary of the Invention

[0005] The purpose of this invention is to address the deficiencies in the existing technology by proposing a pesticide residue removal device for fruit and vegetable processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

First gears are installed at both ends of the rotating rod, and the first gears mesh with the vertical racks for transmission.

[0013] Furthermore, the cleaning and auxiliary discharge assembly includes two transverse guide rails and a transverse rack symmetrically installed on the inner walls of the front and rear sides of the housing. The transverse rack is located on the upper side of the transverse guide rails and its teeth are set downwards. A transverse lead screw is rotatably installed in each transverse guide rail. A slide is threaded on the transverse lead screw. Guide sliders are fixed on the upper and lower sides of the slide. The guide sliders slide and match the guide rail grooves of the transverse guide rails. One end of the transverse lead screw is installed on the drive shaft of a second motor. The second motor is installed on the outside of the housing.

[0014] A horizontal shaft is rotatably mounted between the two slides. Multiple perforated plates are radially mounted on the horizontal shaft. A second gear is mounted at both ends of the horizontal shaft, and the second gear meshes with a transverse rack on the same side for transmission.

[0015] Furthermore, the drainage and cleaning assembly includes a frame movably disposed within the sewage discharge chamber of the housing. The frame is composed of multiple horizontally and vertically arranged strip plates, with upwardly positioned sealing plugs installed at the joints between the horizontal and vertical strip plates. The ends of the horizontal strip plates are slidably disposed within vertical guide rails, which are fixed to the inner side wall of the housing. The ends of the horizontal strip plates are threadedly installed to a vertical lead screw through threaded holes. The upper end of the vertical lead screw is rotatably mounted to the bottom surface of the filter base plate, and the lower end of the vertical lead screw is rotatably mounted to a support seat via a bearing. The support seat is fixed to the inner side wall of the housing. A worm gear is installed at the lower end of the vertical lead screw. Multiple rotating shafts are rotatably mounted between the left and right inner walls of the housing. Worms are installed on the rotating shafts near the vertical lead screw, and the worms mesh with the worm gears for transmission. The left end of each rotating shaft extends to the outside of the housing and is driven by a pulley assembly. The left end of one of the rotating shafts is connected to the drive shaft of a third motor, which is mounted on the outside of the housing.

[0016] Furthermore, the pulley assembly includes pulleys mounted on the end of the shaft, and the pulleys are connected by a belt for transmission.

[0017] Furthermore, the inner top surface of the bottom plate of the box is inclined from left to right, and the height of its left surface is greater than the height of its right surface. The top of the auxiliary sewage pipe is connected to the inner side of the box at the bottom of the discharge port, and the bottom of the auxiliary sewage pipe is connected to the inside of the main sewage pipe. Moreover, the height of the connection point between the auxiliary sewage pipe and the main sewage pipe is greater than the height of the connection point between the top of the main sewage pipe and the right side of the box.

[0018] Furthermore, both the feeding conveyor belt and the discharging conveyor belt include multiple conveying rollers driven by a motor, and the conveyor belt is mounted on the surface of the multiple conveying rollers together, and the conveyor belt is provided with through holes.

[0019] The discharge conveyor belt is inclined and installed inside the discharge port, with the left end of the conveyor belt located on the lower side and its height lower than the right end of the filter base plate.

[0020] Furthermore, a one-way baffle assembly is provided on the right side of the filter base plate and above the left side of the discharge conveyor belt.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention includes a feeding conveyor belt and an unloading conveyor belt, allowing fruits to be continuously and orderly transported into the box for cleaning. After cleaning, the fruits can be output in an orderly manner, avoiding the inconvenience of subsequent cleaning caused by a large batch of fruits and vegetables being fed in at once, which could lead to incomplete removal of pesticide residues. Furthermore, the unloading process allows water to be drained, reducing the residual moisture on the surface of the fruits and vegetables and facilitating subsequent processing.

[0023] 2. In this invention, the water pump delivers the cleaning solution into the tank through pipes and nozzles, immersing and cleaning the fruits and vegetables inside. During cleaning, the cleaning and auxiliary discharge components agitate the fruits and vegetables, causing them to move within the cleaning solution, thereby improving the cleanliness and efficiency of the cleaning process. After cleaning, the fruits and vegetables can be discharged when the door panel in the discharge door assembly is opened. With the cooperation of the cleaning and auxiliary discharge components, the fruits and vegetables can be pushed towards the door opening and the discharge conveyor belt, allowing them to be smoothly received by the discharge conveyor belt and transported out of the entire device to complete the cleaning operation. Furthermore, water can be drained during discharge, facilitating subsequent processing.

[0024] 3. In this invention, when fruits and vegetables need to be discharged, the drainage and cleaning hole assembly is opened, and water and impurities therein can be discharged through the drainage hole into the sewage chamber of the box. Sewage and impurities can be discharged from the main sewage pipe. The flushing pipe is connected to a flushing pump, which can flush the inside of the sewage chamber, so that the sewage and impurities inside can be discharged smoothly and thoroughly. The drainage and cleaning hole assembly also unclogs the drainage hole, preventing the inner wall of the drainage hole from being blocked by impurities, and ensuring its normal sewage discharge use in the future.

[0025] In summary, this invention can continuously and orderly transport fruits and vegetables, allowing them to smoothly enter the box for pesticide residue cleaning. During cleaning, the fruits and vegetables can be agitated to ensure that a large quantity of fruits and vegetables can be cleaned evenly, improving the cleaning degree and efficiency. Furthermore, the materials can be discharged in an orderly manner and water can be drained. In addition, the internal parts of the device can be effectively cleaned to maintain its own cleanliness, avoid internal blockage, reduce subsequent cleaning costs, and reduce device downtime.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0037] Reference Figure 1-8 A pesticide residue removal device for fruit and vegetable processing includes a first support 1 and a second support 5. A box 2 is installed on the upper part of the first support 1. A receiving port 3 is provided on the left side of the top of the box 2, and a discharge port 6 is provided on the right side of the top of the box 2. A feeding conveyor belt 4 is installed on the upper part of the second support 5. The feeding conveyor belt 4 is connected to the receiving port 3. A discharge conveyor belt 7 is provided inside the discharge port 6, and the discharge conveyor belt 7 is inclined.

[0038] A pipe 8 is installed on the top of the housing 2, and the inlet of the pipe 8 is connected to the outlet of the water pump. Multiple nozzles 9 facing the inside of the housing 2 are installed on the surface of the pipe 8. A filter-type bottom plate 14 is installed inside the housing 2. Multiple drainage holes 15 are opened through the filter-type bottom plate 14. The cleaning chamber is located inside the housing 2 and above the filter-type bottom plate 14. The sewage discharge chamber is located below the filter-type bottom plate 14. A flushing pipe is installed on the front side of the housing 2 and below the filter-type bottom plate 14. The flushing pipe is connected to the inside of the sewage discharge chamber and is connected to the flushing pump. A main sewage discharge pipe 13 is installed on the bottom right side of the housing 2. An auxiliary sewage discharge pipe 17 is installed on the bottom right side of the housing 2 and at the bottom of the discharge port 6.

[0039] The right side inside the housing 2 is provided with a discharge door assembly 10, which is located above the filter bottom plate 14 and between the cleaning chamber and the discharge port 6.

[0040] The cleaning chamber of housing 2 is equipped with a cleaning and auxiliary discharge assembly 11;

[0041] The drain chamber of the box 2 is equipped with a drain cleaning hole assembly 12.

[0042] The fruits and vegetables to be cleaned are fed from the feeding conveyor belt 4 and gradually transported into the box 2. The cleaning solution is delivered into the box 2 by an external water pump. The cleaning solution is sprayed into the box 2 from the nozzle 9 installed at the pipe 8, thereby soaking and cleaning the fruits and vegetables. The type of cleaning solution is selected according to actual needs and belongs to the prior art. This application does not limit it.

[0043] Fruits and vegetables are soaked in the cleaning solution inside the container 2. The cleaning and auxiliary discharge assembly 11 agitates both the solution and the vegetables, keeping them in motion for more thorough soaking and a higher cleaning effect. This also helps separate impurities such as leaves, soil, and other debris adsorbed on the surface, especially facilitating soil sedimentation at the bottom. After cleaning, the drainage hole assembly 12 is opened to discharge wastewater, and clean water is sprayed through pipe 8 and nozzle 9 for surface rinsing. Wastewater is discharged from the main drain pipe 13. The discharge door assembly 10 is then opened, and the cleaning and auxiliary discharge assembly 11 again moves the fruits and vegetables towards the doorway, allowing them to enter the working range of the discharge conveyor belt 7. The fruits and vegetables are then conveyed out of the container 2 by the discharge conveyor belt 7. During this conveying process, surface moisture is drained, facilitating subsequent processing.

[0044] Furthermore, the material discharge gate assembly 10 includes a door panel 101 slidably mounted on the right side plate of the housing 2. The right side plate of the housing 2 has a door opening that matches the door panel 101. Vertical racks 102 are installed at both the front and rear ends of the left side of the door panel 101, and guide grooves corresponding to the vertical racks 102 are opened on the right side plate of the housing 2. The vertical racks 102 slide in the guide grooves. A rotating rod 103 is rotatably mounted on the right side plate of the housing 2. One end of the rotating rod 103 is connected to the drive shaft of the first motor 105. The first motor 105 is mounted on the left side plate of the housing 2. First gears 104 are installed at both ends of the rotating rod 103. The first gears 104 mesh with the vertical racks 102 for transmission.

[0045] When the door panel 101 needs to be opened, the first motor 105 drives the rotating rod 103 to rotate, and the first gear 104 meshes with the vertical rack 102 to drive the vertical rack 102 and the door panel 101 to move upward at the same time. At this time, the door panel 101 can be gradually opened, making it convenient for fruits and vegetables to move to the discharge conveyor belt 7.

[0046] Furthermore, the cleaning and auxiliary discharge assembly 11 includes two transverse guide rails 111 and a transverse rack 114 symmetrically installed on the inner walls of the front and rear sides of the housing 2. The transverse rack 114 is located on the upper side of the transverse guide rails 111 with its teeth facing downward. A transverse lead screw 112 is rotatably installed in each of the transverse guide rails 111. A slide block 118 is threaded on the transverse lead screw 112. Guide sliders 119 are fixed on the upper and lower sides of the slide block 118. The guide sliders 119 slide and match the guide rail grooves of the transverse guide rails 111. One end of the transverse lead screw 112 is installed on the drive shaft of the second motor 113. The second motor 113 is installed on the outside of the housing 2.

[0047] A horizontal shaft 115 is rotatably mounted between the two slides 118. Multiple perforated plates 116 are radially mounted on the horizontal shaft 115. A second gear 117 is mounted at both ends of the horizontal shaft 115. The second gear 117 meshes with a transverse rack 114 on the same side for transmission.

[0048] The PLC controller can simultaneously control the operation of two second motors 113. The second motors 113 drive the corresponding transverse lead screws 112 to rotate. The transverse lead screws 112 drive the slide block 118 and the guide slider 119 to move laterally relative to the transverse guide rail 111. Since the second gear 117 meshes with the transverse rack 114, the transverse shaft 115 can be controlled to rotate relative to the slide block 118. At this time, the multiple mesh plates 116 on the transverse shaft 115 can rotate. When the cleaning liquid is injected into the box 2, the rotating mesh plates 116 can disturb the fruits and vegetables in the box 2. After the cleaning liquid in the box 2 is discharged, the mesh plates 116 can also push the fruits and vegetables towards the doorway, making it convenient for the fruits and vegetables to enter the working range of the discharge conveyor belt 7.

[0049] Furthermore, the drainage hole cleaning assembly 12 includes a frame 121 movably disposed within the sewage chamber of the housing 2. The frame 121 is composed of multiple horizontally and vertically arranged strip plates, and an upwardly positioned sealing plug 122 is installed at the connection between the horizontal and vertical strip plates. The sealing plug 122 is cylindrical and consists of a central rod and a rubber sleeve wrapped around the outer surface of the central rod. The rubber sleeve is in contact with the inner wall of the drainage hole through compression friction. The ends of the horizontal strip plates are slidably disposed within the vertical guide rail 123, which is fixed to the inner side wall of the housing 2. The ends of the horizontal strip plates are threadedly installed with a vertical lead screw 124 through threaded holes. The upper end of the vertical lead screw 124 is connected to the vertical lead screw 124 through threaded holes. The bottom surface of the filter base plate 14 is rotatably mounted. The lower end of the vertical lead screw 124 is rotatably mounted with a support seat via a bearing. The support seat is fixed to the inner side wall of the box 2. The lower end of the vertical lead screw 124 is mounted with a worm gear 127. Multiple rotating shafts 125 are rotatably mounted between the left and right inner walls of the box 2. A worm gear 126 is mounted on the rotating shaft 125 near the vertical lead screw 124. The worm gear 126 meshes with the worm gear 127 for transmission. The left end of each rotating shaft 125 extends to the outside of the box 2 and is transmitted between them via a pulley assembly 128. The left end of one of the rotating shafts 125 is connected to the drive shaft of the third motor 129. The third motor 129 is mounted on the outside of the box 2.

[0050] Furthermore, the pulley assembly 128 includes pulleys mounted at the end of the shaft 125, and the pulleys are connected by a belt for transmission.

[0051] After the fruit and vegetable washing is completed, the drainage hole cleaning assembly 12 can be controlled to operate. The third motor 129 is turned on and drives the rotating rod 125 to rotate. Multiple rotating rods 125 are transmitted through the belt pulley assembly 128, so multiple rotating rods 125 can rotate at the same time. When rotating, the worm gear 126 meshes with the worm wheel 127. When the worm wheel 127 rotates, it can drive the corresponding vertical lead screw 124 to rotate. The vertical lead screw 124 is threaded to the end of the horizontal strip plate of the frame 121, so the entire frame 121 can be controlled to slide vertically relative to the vertical guide rail 123 and the inner wall of the box 2. When moving downward, the sealing plug 122 can leave the drainage hole 15. At this time, the cleaning liquid in the cleaning chamber of the box 2 can be discharged from the drainage hole 15 into the sewage discharge chamber, and then discharged from the main sewage pipe 13. When discharging wastewater (contaminated cleaning solution), an external flushing pump can be used to flush clean water into the sewage discharge chamber from the flushing pipe. At the same time, clean water can also be flushed into the tank 2 through pipe 8 and nozzle 9 with the help of the water pump, thereby accelerating the cleaning efficiency of the tank 2, maintaining the cleanliness of the tank 2, and facilitating subsequent reuse.

[0052] Furthermore, the inner top surface of the bottom plate of the housing 2 slopes from left to right, with the height of the left side surface being greater than the height of the right side surface. The top of the auxiliary drain pipe 17 is connected to the inner side of the housing 2 at the bottom of the discharge port 6, and the bottom of the auxiliary drain pipe 17 is connected to the interior of the main drain pipe 13. Moreover, the connection point between the auxiliary drain pipe 17 and the main drain pipe 13 is at a greater height than the connection point between the top of the main drain pipe 13 and the right side of the housing 2. The bottom plate of the housing 2 is sloping and tilts towards the main drain pipe 13, which facilitates the drainage operation. When fruits and vegetables are conveyed and discharged through the discharge conveyor belt 7, the drained water can be collected in the auxiliary drain pipe 17, and then discharged from the auxiliary drain pipe 17 into the main drain pipe 13, and finally discharged from the entire device.

[0053] Furthermore, both the feeding conveyor belt 4 and the discharging conveyor belt 7 include multiple conveying rollers driven by a motor. The surface of the multiple conveying rollers is wrapped with a conveyor belt, and the conveyor belt is provided with through holes.

[0054] The discharge conveyor belt 7 is inclined and set inside the discharge port 6. The left end of the conveyor belt is located on the lower side and its height is lower than the right end of the filter base plate 14.

[0055] like Figure 1 and Figure 2 As shown, partitions are also installed on the conveyor belts of the feeding conveyor belt 4 and the discharging conveyor belt 7. The partitions are used to increase the traction effect when transporting fruits and vegetables, making it more convenient to transport them.

[0056] Furthermore, a one-way baffle assembly 16 is provided on the right side of the filter base plate 14 and above the left side of the discharge conveyor belt 7. The one-way baffle assembly 16 includes a baffle, and a shaft is installed at one end of the baffle near the housing 2 and the filter base plate 14. The shaft is rotatably installed on the inner wall of the housing 2 near the bottom of the discharge port 6. A limiting plate is also provided at the right end of the filter base plate 14. The limiting plate is used to limit the excessive downward swing of the baffle, so that fruits and vegetables may get stuck or fall below the discharge conveyor belt 7. The one-way baffle assembly 16 can more conveniently transport fruits and vegetables into the working range of the discharge conveyor belt 7.
