Abstract
Description
Technical Field
[0001] This invention relates to the technical field of automatic cleaning and processing devices for Shanghai bok choy, specifically to an automatic cleaning and processing device for Shanghai bok choy. Background Technology
[0002] In industrialized vegetable production, vegetables must first be washed to remove dirt, sand, and peeling skin from their surface before being sent to the next processing stage. Currently, the most common vegetable washing equipment is the spray washing machine, which uses a simple spraying method to rinse the vegetables with a mist of water sprayed from top to bottom. However, its washing capacity is limited, especially as there are often blind spots at the bottom of the vegetables. In practice, it has been found that it is difficult to thoroughly clean the vegetables. Furthermore, when the dirt and other debris adhering to the vegetable surface are strongly bonded, the cleanliness of the vegetables cannot meet the requirements, and thorough cleaning is difficult. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic cleaning and processing device for Shanghai bok choy to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solutions: This invention discloses an automatic cleaning and processing device for Shanghai bok choy, comprising a cleaning machine, which includes a frame, a conveying mechanism, a spraying mechanism, and a blower mechanism. The conveying mechanism includes a drain conveyor belt, a drive shaft, a driven shaft, and a drive motor. The drain conveyor belt has evenly distributed drain holes and rotates on the drive shaft and the driven shaft. The drive motor is connected to the drive shaft and controls its rotation. The drive shaft and the driven shaft are rotatably connected to the frame, and the drive motor is fixed to one end of the frame. The spraying mechanism includes a water pump and a spray pipe. The water pump is connected to the spray pipe through a pipe. The water pump is fixed to one side of the frame. The spray pipe includes several water pipes that are fixed parallel to the top of the frame. The spray pipe is located above the dewatering conveyor belt and is equipped with several downward-facing nozzles. The blower mechanism includes a blower and a blower pipe. The blower is connected to the blower pipe through a pipe. The blower is fixed to one end of the frame. The blower pipe includes several air pipes that are fixed parallel to the bottom of the frame. The blower pipe is located below the drain conveyor belt and has several upward-facing air holes.
[0005] As an improvement, the drain conveyor belt includes a flat section and a sloping section, with the spray pipe and air blower pipe located above and below the flat section, respectively.
[0006] As an improvement, side panels are provided on both sides of the drain conveyor belt of the frame.
[0007] As an improvement, the water pump is connected to the water tank.
[0008] As an improvement, the flat end of the drain conveyor belt is the feeding end, and the feeding end of the frame is provided with an inclined discharge guide plate.
[0009] The advantages of this invention compared to existing technologies are as follows: When the cleaning machine is working, the nozzle faces downward to rinse the upper part of the Shanghai bok choy, while the lower air blower blows high-pressure air upward. The high-pressure air passes through the drain holes of the drain conveyor belt and impacts the Shanghai bok choy with moisture on its surface, enhancing the peristalsis of moisture on the lower surface of the Shanghai bok choy and forming an upward rinsing effect. This avoids blind spots in the lower cleaning area and also generates water bubble bursts, forming a compound force that helps to remove highly adhesive impurities from the surface of the Shanghai bok choy, further promoting the cleaning effect and making it easy to clean thoroughly.

[0022] This embodiment, in conjunction with the accompanying drawings, provides a detailed description of an automatic cleaning and processing device for Shanghai bok choy.
[0023] This embodiment describes an automatic cleaning and processing device for Shanghai bok choy, such as... Figure 1The cleaning machine includes a frame 1, a conveying mechanism 2, a spraying mechanism 3, and a blower mechanism 4. The conveying mechanism 2 includes a drain conveyor belt 21, a drive shaft, a driven shaft, and a drive motor 22. The drain conveyor belt 21 has evenly distributed drain holes with a diameter of 2-5 cm. The drain conveyor belt 21 rotates on the drive shaft and the driven shaft. The drive motor 22 is connected to the drive shaft and controls its rotation. The drive shaft and the driven shaft are rotatably connected to the frame 1. The drive motor 22 is fixed to one end of the frame 1. like Figure 1 The spraying mechanism 3 includes a water pump 31 and a spray pipe 32. The water pump 31 is connected to the spray pipe 32 through a pipe. The water pump 31 is fixed to one side of the frame 1 and is connected to a water source. The spray pipe 32 includes several connected water pipes that are fixed parallel to the top of the frame 1. The spray pipe 32 is located above the dewatering conveyor belt 21. The spray pipe 32 is provided with several downward-facing nozzles 33. The nozzles 33 are conventional rotating nozzles that spray spiral water. like Figure 3 , 5 The blower mechanism 4 includes a blower 41 and a blower pipe 42. The blower 41 is connected to the blower pipe 42 through a pipe. The blower 41 is fixed to one end of the frame 1. The blower pipe 42 includes several connected air pipes that are fixed parallel to the bottom of the frame 1. The blower pipe 42 is located below the drain conveyor belt 21. The blower pipe 42 is provided with several upward-facing blower holes 43. The blower holes 43 are smaller than the drain holes and have a diameter of 1-2 cm.
[0024] like Figure 2 , 3 The drain conveyor belt 21 includes a flat section 211 and a sloping section 212. The spray pipe 32 and the air blower 42 are located above and below the flat section, respectively. The sloping section is used for draining water.
[0025] like Figure 2 , 3 The frame 1 has guardrails 11 on both sides of the drain conveyor belt 21. The guardrails 11 block the Shanghai bok choy, and the flat section of the guardrails 11 has filter holes to prevent water accumulation.
[0026] like Figure 2 The water pump 31 is connected to the water tank 34. The water tank 34 can be located either near or far.
[0027] like Figure 1 , 2 The flat end of the drain conveyor belt 21 is the feeding end, and the feeding end of the frame 1 is provided with an inclined discharge guide plate 12. Shanghai bok choy slides from the discharge guide plate 12 onto the drain conveyor belt 21.
[0028] like Figure 2The system includes a root cutter located near the feeding end. The root cutter comprises a conveyor belt 5 and a circular cutter 6 on one side. The conveyor belt 5 is equipped with evenly distributed partitions 51. Both the conveyor belt 5 and the circular cutter 6 are driven by a motor. The output end of the conveyor belt 5 is located above the discharge guide plate 12. Shanghai bok choy is neatly stacked between the partitions 51, with its roots facing the circular cutter 6. During the conveying process, the roots are cut by the circular cutter 6.
[0029] The packaging machine uses an existing film packaging machine, which is placed at the sloping end of the washing machine to receive and package the washed and drained Shanghai bok choy.
[0030] In practical implementation, a root cutting machine and packaging machine can be used as needed. When the washing machine is working, the drive motor 22, water pump 31, and blower 41 are started. Shanghai bok choy is fed onto the drain conveyor belt 21 from the feed guide plate 12. During the horizontal conveying process, the upper matrix-distributed rotating nozzles 33 spray water onto the upper part of the Shanghai bok choy, forming a downward flush. Simultaneously, the lower matrix-distributed air holes 43 blow high-pressure air upwards. The high-pressure air passes through the drain holes of the drain conveyor belt 21 and impacts the Shanghai bok choy with moisture on its surface, strengthening the peristalsis of moisture on the lower surface of the Shanghai bok choy, forming an upward flush. Simultaneously, water bubbles burst, creating a compound impact force, which helps to remove strongly adhesive impurities from the surface of the Shanghai bok choy, further promoting the cleaning effect. After passing through the horizontal section, the Shanghai bok choy continues to drain as it rises along the slope section, and is finally output.
[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
