Description

Technical Field

[0002] With the development of the clean vegetable industry, fruit and vegetable cleaning technology, as a key link in the processing of the clean vegetable industry, has received attention for its research and development. With the rapid expansion of my country's cherry cultivation area and the annual increase in total output, commercial processing technologies such as cherry storage and preservation are also improving. Cherry cleaning, as an indispensable link in the cherry storage process, plays an important role in ensuring cherry food safety.

[0003] The gas flushing part of the existing cherry washing equipment often cleans the surface of the cherry through water jets and rising bubbles, and drives the cherries forward through the push plate of the perforated conveyor belt. This method is mainly used for small cherries. Since large cherries are large in size and have soft skin, their surface resistance to the impact of water jets is poor and they will be damaged during water flushing. Since the gas washes the cherries through the through holes of the conveyor belt, it is difficult for the gas to push the large cherries to roll vertically upward, making it difficult to completely clean the large cherries. In addition, the cherry washing equipment cannot screen out the leaves, and the leaves will enter the next processing link together with the washed cherries. It is necessary to manually identify and separate impurities during the cleaning or subsequent processing links, which greatly increases the labor cost. Summary of the invention

DETAILED DESCRIPTION

[0038] Example 1

[0039] A large cherry cleaning and packaging equipment, such as Figure 1-Figure 9 As shown, it comprises a cleaning box 1, a water outlet valve 101 is installed at the bottom of the front side of the cleaning box 1, a U-shaped plate 2 is sealed and fixed in the cleaning box 1, both sides of one end of the U-shaped plate 2 are supported by a support frame, a cleaning mechanism 3 is installed in the cleaning box 1, a conveying mechanism 4 is installed in the U-shaped plate 2, and a packaging mechanism 5 is arranged below the conveying mechanism 4;

[0040] The cleaning mechanism 3 includes a first support plate 301 and a first air pipe 302. The first support plate 301 is fixedly connected in the cleaning box 1. A plurality of square through grooves are provided on one side of the first support plate 301. A plurality of groups of track rods 3011 are fixedly connected linearly between the inner wall of the cleaning box 1 and the first support plate 301. Each square through groove corresponds to each group of track rods 3011. Adjacent track rods 3011 are staggered and distributed in parallel along the vertical direction. The first air pipe 302 is fixedly connected linearly through the cleaning box 1. A fan-shaped nozzle 3021 is fixedly connected linearly on the first air pipe 302.

[0041] The conveying mechanism 4 includes a transmission roller 402, and both ends of the U-shaped plate 2 are rotatably connected to the transmission roller 402. A plurality of limiting grooves are provided on the transmission roller 402, and a plurality of first corrugated belts 4021 and a plurality of second corrugated belts 4022 are respectively provided in the plurality of limiting grooves. Wave grooves are provided on the outer sides of the first corrugated belt 4021 and the second corrugated belt 4022. There are two first corrugated belts 4021 between two adjacent second corrugated belts 4022, and two adjacent first corrugated belts 4021 are symmetrical to each other. Two adjacent first corrugated belts 4021 correspond to a square through groove of the first support plate 301. The first corrugated belt 4021 has a larger inclination angle on the side close to the second corrugated belt 4022, and a first transmission group 401 is installed on the outer side of the transmission roller 402 located at the upper end of the U-shaped plate 2.

[0042] The cleaning mechanism 3 also includes a first motor 303. The first motor 303 is fixedly connected to one side of the U-shaped plate 2 through a motor frame. The output end of the first motor 303 is connected to the first transmission group 401. The first transmission group 401 includes a first driving pulley, a first driven pulley and a first transmission belt. The outer side of the output end of the first motor 303 is fixedly connected to the first driving pulley, and the first driven pulley is fixedly connected to one end of the transmission roller 402. The first driving pulley and the first driven pulley are jointly sleeved with the outer walls. The output end of the first motor 303 passes through the U-shaped plate 2 and is installed with an air transmission unit 304.

[0043] The air delivery unit 304 includes a first crankshaft 3041 and a fan housing 3042. The output end of the first motor 303 is fixedly connected to the first crankshaft 3041. The first crankshaft 3041 is located in the U-shaped plate 2 and is rotatably connected to the U-shaped plate 2. The fan housing 3042 is fixedly connected to one side of the U-shaped plate 2. An air inlet is provided at one end of the fan housing 3042. The diameter of the air inlet is larger than the diameter of the first crankshaft 3041. The first crankshaft 3041 passes through the fan housing 3042, and the outer wall is circumferentially distributed and fixedly connected with fan blades 3043. An air outlet 3044 is provided on the outer wall of the fan housing 3042, and the air outlet 3044 is connected to the first air delivery pipe 302 through an air duct.

[0044] In the initial state, the water outlet valve 101 is not opened, and the staff introduces an external water source into the cleaning box 1 until the cleaning box 1 is filled with water, and starts the first motor 303. The output shaft of the first motor 303 rotates to drive the first crankshaft 3041 to rotate, and the first crankshaft 3041 drives the fan blades 3043 to rotate synchronously. The rotation of the fan blades 3043 pushes and squeezes the air into the air outlet 3044. On the one hand, the air pressure in the fan housing 3042 is reduced, so that the fan housing 3042 inhales air from the air inlet. On the other hand, the air enters the airway through the air outlet 3044 and is sprayed by the fan-shaped nozzle 3021 through the first air supply pipe 302, forming bubbles in the water. The bubble trajectory sprayed by the fan-shaped nozzle 3021 is fan-shaped, and the bubble trajectories sprayed by the fan-shaped nozzle 3021 installed on the same first air supply pipe 302 overlap with each other to form an inclined bubble wall, such as Fig. 9 As shown in A1, when the air bubble moves, it drives the nearby water to move with the same trend. When the water at the bottom of the cleaning box 1 rises to the water surface with the air bubble, the water at the top of the cleaning box 1 will be squeezed by the water at the bottom of the cleaning box 1 and move away from the air bubble in the horizontal direction until the water at the top of the cleaning box 1 collides with the inner wall of the cleaning box 1 or another horizontally moving water flow. At this time, due to the rise of the water near the air bubble at the bottom of the cleaning box 1, a temporary cavity appears at the bottom of the cleaning box 1, and the water around it will flow to the temporary cavity at the bottom of the cleaning box 1 due to the hydraulic pressure, so that the temporary cavity is filled. When the temporary cavity is filled, the macroscopic flow direction of the water is toward the flow direction of the air bubble, thereby forming a circulating vortex. Then, cherries are poured into the cleaning box 1, and the cherries fall into the water and move downward along the track rod 3011. Since the circulating vortex is caused by the rising of the air bubble and the flow of the surrounding water, the flow velocity of the circulating vortex near the air bubble is higher than the flow velocity far away from the air bubble, and the flow velocity of the outer circle of the circulating vortex is greater than the flow velocity of the inner circle of the circulating vortex. Therefore, the cherries are moved. During the process, the circulating eddy current acts on the surface of the cherry, so that the upper and lower parts of the cherry in the water are subjected to different eddy current thrusts, the torque of the lower part of the cherry is greater than the torque of the upper part of the cherry, thereby driving the cherry to roll, and when the cherry contacts the air bubble, the bubble surface and the cherry surface flexibly collide and rub, so that the attachments on the surface of the cherry are hit by the air bubble and attached to the bubble surface under the action of the tension of the bubble surface, and finally the attachments are suspended in the water when the bubble bursts and releases, completing the flexible cleaning of the cherry; compared with the existing horizontal conveyor belt air bubble cleaning, the cleaning method uses the air bubble and the gravity of the cherry itself as power to drive the cherry forward, and the cleaning method can make the cherry roll, so that the flexible cleaning of the air bubble can fully act on the surface of the cherry, thereby improving the cleaning effect of the cherry surface, while the existing parallel conveyor belt cleaning method has poor bubble cleaning effect due to the sieve holes on the conveyor belt that reduce the bubble flow rate, and the cherry cannot be moved, so the cherry can only be cleaned at the bottom.

[0045] In the process of washing cherries, Fig. 9As shown in B1, multiple cherries form an obstacle on the track rod 3011 to block the water flow, causing part of the circulating vortex to flow along the surface of the cherries and be deformed. At this time, the circulating vortex has a smaller volume and a faster flow rate, and the flow rate of the circulating vortex on the right side of the bubble is greater than the flow rate of the circulating vortex on the left side of the bubble. Due to the different flow rates of the circulating vortices on both sides of the bubble, the water at the bottom of the cleaning box 1 generates a water flow that flows toward the water outlet valve 101 as a whole under the joint action of multiple water flows. The water flow will drive the washed attachments to move at the same time, and when the water flow contacts the inner wall of the cleaning box 1, the attachments will be The attached objects are accumulated at the corners of the cleaning box 1 which are less affected by the water flow, so as to reduce the flow of the attached objects and prevent the cherries from being contaminated. The accumulated attached objects are convenient for subsequent cleaning. The water flow will continue to flow upward along the inner wall of the cleaning box 1 to the water surface, and move along the water surface toward the U-shaped plate 2 to flow back into the circulating vortex, thereby forming a large-scale circulating current. The large-scale circulating current is superimposed on the circulating vortex, so that the cherries can continue to move toward the U-shaped plate 2, preventing the cherry stalks from being stuck by the track rod 3011 and becoming unable to move. By opening the water outlet valve 101, the attached objects can be quickly discharged while changing the water, and the cleaning of the cleaning box 1 is completed.

[0046] Example 2

[0047] On the basis of Example 1, Figure 2 , Figure 5-Figure 8 As shown, the conveying mechanism 4 also includes a push rack 403, the push rack 403 is slidably connected inside the U-shaped plate 2, a linear slide groove is provided at the bottom of the push rack 403, the first crankshaft 3041 passes through the linear slide groove of the push rack 403 and is slidably connected thereto, a plurality of plate-like protrusions are provided at the top of the push rack 403, and a rectangular through groove is provided between the plate-like protrusions, the plate-like protrusions are all located between two adjacent first corrugated bands 4021, a second air pipe 404 is fixedly connected to the inner wall of the U-shaped plate 2 in a through-type manner, a plurality of conical nozzles 4041 are linearly distributed, fixedly connected and connected to the second air pipe 404, and an air outlet 3044 of the fan housing 3042 is connected to the second air pipe 404 through an air duct.

[0048] After the cherries are cleaned in the cleaning box 1, they move to the first corrugated belt 4021. At this time, the output shaft of the first motor 303 rotates through the first transmission group 401 to drive the transmission roller 402 and the first crankshaft 3041 to rotate synchronously. The transmission roller 402 rotates to make the first corrugated belt 4021 and the second corrugated belt 4022 rotate synchronously. When the cherries move above the first corrugated belt 4021, the corrugated grooves of the first corrugated belt 4021 will hold up the cherries and limit the cherries, so that the first corrugated belt 4021 drives the cherries The movement continues until the cherry moves to the push rack 403. At this time, the first crankshaft 3041 rotates and slides in the linear slide groove at the bottom of the push rack 403, thereby pushing the push rack 403 to slide up and down in the U-shaped plate 2. The push rack 403 extends between two adjacent first corrugated belts 4021 and pushes up the cherry. The cherry leaves the corrugated groove of the first corrugated belt 4021, rolls along the inclined surface of the first corrugated belt 4021, and rolls into the corrugated groove of the second corrugated belt 4022. At this time, the first corrugated belt 4021 and the second corrugated belt 4022 are in contact with each other. The wave grooves of the belt 4022 clamp the big cherry together. If there are leaves left on the first wave belt 4021, the leaves will also be pushed up by the push frame 403. The pushed leaves are in an inclined state and slide along the inclined surface of the first wave belt 4021. Since the thickness of the leaves is much smaller than the diameter of the big cherry, the inclined leaves can fall along the inclined surface of the first wave belt 4021 and fall on the U-shaped plate 2 through the rectangular through grooves on the push frame 403, thereby separating the leaves from the big cherry; the big cherry continues to move with the first wave belt 4021 and the first wave belt 4021. The second corrugated belt 4022 moves, and when the big cherry is located above the conical nozzle 4041, air enters the second air pipe 404 through the airway, and is sprayed onto the surface of the big cherry through the conical nozzle 4041, so that the moisture on the surface of the big cherry is quickly dried, thereby achieving the drying process of the big cherry; if there are leaves adhering to the first corrugated belt 4021 and the second corrugated belt 4022 that cannot fall off, the air sprayed by the conical nozzle 4041 will quickly dry the water on the surface of the leaves, and blow the leaves to make them fall off, thereby further completing the cleaning of the leaves.

A third star frame 5064 is symmetrically fixed to the wall, a packaging cover is placed above the side protrusion of the third star frame 5064, third threads are provided at both ends of the third driving rod 5062, fourth threads are provided at both ends of the fourth driving rod 5065, the third threads and the fourth threads are both at an elevation angle of 45 degrees and mesh with each other, a fourth star frame 5066 is symmetrically fixed to the outer wall of the fourth driving rod 5065, the fourth star frame 5066 is inclined at 45 degrees, and a packaging cover is clamped in the recess of the fourth star frame 5066.

[0054] The second unloading unit 506 also includes a second gear set 5063 and a second support plate 5071. The second gear set 5063 is composed of a second driving gear and a second driven gear. Both ends of the third driving rod 5062 pass through the second loading frame 5061 and are fixedly connected to the second driven gear of the second gear set 5063. The second driving gear is connected to the second transmission group 5023, and the second driving gear is meshed with the second driven gear. A second crankshaft 5073 is installed on one side of the second driven gear. The second crankshaft 5073 passes through the second loading frame 5061 and is slidably connected to the sliding sleeve 5074. The bottom of the second loading frame 5061 is fixedly connected to the second support plate 5071. The support plate 5071, the second support plate 5071 is symmetrically fixed with an inclined groove plate 5072 at the bottom, an inclined groove is opened on one side of the inclined groove plate 5072, a sliding rod is symmetrically fixed with the outer wall of the sliding sleeve 5074, the sliding rod is slidably connected with the inclined groove of the inclined groove plate 5072, a push block 5075 is fixed at one end of the sliding sleeve 5074, the second transmission group 5023 includes a second driving pulley, a second driven pulley and a second transmission belt, the first driving rod 5022 is fixed with the second driving pulley, the second driven gear of one of the second gear groups 5063 is fixed with the second driven pulley, and a second transmission belt is transmitted between the second driving pulley and the second driven pulley.

[0055] When the first motor 303 is started, the second motor 503 is started at the same time. The output shaft of the second motor 503 rotates to drive the conveyor belt 5011 to move, and drives the first driving rod 5022 to rotate through the first gear set 5024. The first driving rod 5022 rotates to make the first star frame 5025 rotate ninety degrees to move a packaging bottom box downward. At the same time, the first driving rod 5022 rotates to engage the second thread of the second driving rod 5026 through the first thread, thereby driving the second driving rod 5026 to rotate synchronously. The second driving rod 5026 rotates ninety degrees to make the second star frame 5027 move a packaging bottom box downward. When the second star frame 5027 rotates, the distance moved in the vertical direction by the protrusion of the second star frame 5027 for moving is greater than the distance moved in the vertical direction by the protrusion of the second star frame 5027 for moving. The vertical distance moved by the protrusion of the frame 5025 is shorter, so the packaging bottom box peeled off by the second star-shaped frame 5027 will not be stuck by the packaging bottom box on top of it, and the packaging bottom box finally falls on the conveyor belt 5011; the conveyor belt 5011 transports the packaging bottom box to the bottom of the square funnel 5041, at this time, the second motor 503 is stopped and the third motor 505 is started, and the output shaft of the third motor 505 rotates to drive the cam 5044 to rotate, so that the cam 5044 controls the horizontal slot block 5043 through the sliding rod to squeeze the sliding frame 5042, and the sliding frame 5042 moves downward along the square funnel 5041. When the sliding frame 5042 moves, it will drive the rotating support frame 5045 to squeeze the packaging bottom box. Since the packaging bottom box is made of elastic material and the rotating support frame 5045 passes through the cylindrical The surface contacts and squeezes the packaging bottom box, the packaging bottom box is squeezed and deformed, and the rotating support frame 5045 is squeezed to rotate, and the torsion spring is compressed. The packaging bottom box is finally clamped by the rotating support frame 5045 through its own deformation and the rotation of the rotating support frame 5045. During the rotation of the rotating support frame 5045, the torsion spring is squeezed and released after the packaging bottom box is clamped. The output shaft of the third motor 505 continues to rotate to drive the cam 5044 to rotate, so that the cam 5044 controls the horizontal slot block 5043 through the sliding rod to pull the sliding frame 5042, so that the sliding frame 5042 moves upward until the sliding frame 5042 is reset and the third motor 505 is turned off to stop rotating. At this time, the dried cherries are driven by the first corrugated belt 4021 and the second corrugated belt 4022. 402 falls from the rear and contacts the square funnel 5041. The cherries move downward along the slope of the square funnel 5041 and pass through the square funnel 5041. When the cherries of sufficient weight fall into the packaging bottom box, the rotating support frame 5045 squeezes the torsion spring and triggers the button 5046 until the mass of the cherries in the packaging bottom box reaches the set value. At this time, the rotating support frame 5045 is not enough to clamp the packaging bottom box, so that the cherries fall onto the conveyor belt 5011 with the packaging bottom box. The torsion spring is released and resets the rotating support frame 5045. The button 5046 is released and sends electrical signals to the first motor 303 and the second motor 503 to stop the first motor 303 and start the second motor 503. The output shaft of the second motor 503 drives the conveyor belt 5011 to transport the packaging bottom box.Until the packaging bottom box moves to the bottom of the second loading rack 5061, the first unloading unit 502 repeats the above-mentioned action of placing the packaging bottom box, and the first driving rod 5022 drives the second transmission group 5023 to move, so that the second transmission group 5023 drives the second gear group 5063 to rotate, and drives the third driving rod 5062 and the second crankshaft 5073 to rotate through the second gear group 5063, and the third driving rod 5062 rotates to make the third star frame 5064 rotate 90 degrees to push a packaging cover downward, and at the same time, the third driving rod 5062 rotates to engage the fourth driving rod 5065 through the third thread The fourth thread of the fourth driving rod 5065 is driven to rotate synchronously, and the fourth driving rod 5065 rotates 90 degrees to make the fourth star frame 5066 push a packaging cover downward. Because when the fourth star frame 5066 rotates, the vertical distance moved by the protrusion of the fourth star frame 5064 is shorter than the distance moved in the vertical direction by the protrusion of the fourth star frame 5066 for pushing, so the packaging cover peeled off by the fourth star frame 5066 will not be stuck by the packaging cover on top of it, and the packaging cover finally falls on the packaging bottom box; at the same time, the third driving rod 5062 rotates to make the second gear set 5063 at the other end drive The second crankshaft 5073 thereon is driven to rotate, thereby causing the two second crankshafts 5073 to rotate simultaneously. When the second crankshaft 5073 rotates, it drives the sliding sleeve 5074 to rotate synchronously. At the same time, the sliding rod is limited in the inclined groove of the inclined groove plate 5072, so that the rotational force of the sliding sleeve 5074 is converted into a driving force for sliding along the inclined groove direction. It is worth noting that the sliding sleeve 5074 is located at the top in the initial state, that is, the sliding rod of the sliding sleeve 5074 is located at the top of the inclined groove of the inclined groove plate 5072, to prevent the packaging bottom box and the packaging cover from colliding with the push block 5075 on the sliding sleeve 5074 before they contact each other. , thereby avoiding the situation where the packaging cover cannot be covered on the packaging bottom box. When the sliding sleeve 5074 moves obliquely downward, it will drive the push block 5075 to move above the packaging cover that has been put down, and squeeze the packaging cover so that the packaging cover is covered on the packaging bottom box to complete the packaging. After that, the second crankshaft 5073 continues to rotate, and controls the sliding sleeve 5074 to drive the push block 5075 away from the packaging cover. When the sliding sleeve 5074 moves to the top, the sliding sleeve 5074 drives the push block 5075 to complete the reset; repeat the above packaging steps for big cherries, and the packaged big cherries are conveyed to the collection area by the conveyor belt 5011. ,

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
