Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable screening technology, specifically relating to a fruit and vegetable screening device based on AI vision. Background Technology

[0002] With the modernization and large-scale development of fruit and vegetable planting, the quality and yield of fruit and vegetable planting are also increasing year by year. In order to increase the income of fruit and vegetable products, the harvested fruits and vegetables are often graded and sorted. This not only improves the brand quality of fruit and vegetable products, but also increases the sales value of the fruits and vegetables themselves.

[0003] In reality, many fruit sorting facilities in China still require a large number of workers to sort the fruit by appearance, including size and color, and to remove any moldy or rotten fruit. The fruit is then subjected to internal mechanical sorting. This semi-automated sorting environment reduces work efficiency.

[0004] Therefore, to address the aforementioned technical issues, it is necessary to provide a fruit and vegetable screening device based on AI vision.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a fruit and vegetable screening device based on AI vision, which can solve the problem of low screening efficiency in existing fruit and vegetable screening devices.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A fruit and vegetable sieving device based on AI vision includes: a support frame, a pair of rotating shafts, a pair of chains, multiple mounting components, a mounting rack, multiple pairs of storage baskets, and multiple pushing mechanisms.

[0009] A support plate is fixed inside the support frame. A pair of rotating shafts rotate within the support frame and are respectively located at both ends of the support plate. Each pair of rotating shafts is equipped with a pair of chain teeth. A pair of chains rotate on their respective pairs of chain teeth. Multiple mounting components are installed between the pairs of chains, and a tray is mounted on the upper end of each mounting component. A mounting frame is mounted on the support frame, and a vision scanner is mounted on the mounting frame. Multiple pairs of storage baskets are respectively installed on the side walls of the support frame. Multiple pushing mechanisms are installed on the support plate and are respectively located between each pair of storage baskets. Each pushing mechanism includes a moving groove, a moving component, and a telescopic cylinder. The moving groove is carved into the support plate and is located between a pair of storage baskets. The moving component slides in the moving groove, and the bottom end of the mounting component is located in the moving component. The telescopic cylinder is installed on one side of the support plate, and a telescopic rod connects the telescopic cylinder and the moving component.

[0010] In one embodiment of this utility model, a pair of C-shaped fasteners are fixed to the storage basket, and both C-shaped fasteners are fastened to the side wall of the support frame. The storage basket is secured to the side wall of the support frame by the pair of C-shaped fasteners.

[0011] In one embodiment of this utility model, the installation assembly includes: a pair of crossbars, a support rod, and a first sliding groove. The pair of crossbars rotate between a pair of chains and are fixedly connected. The support rod rotates between the pair of crossbars, the tray is fixed to the top of the support rod, and a sliding head is fixed to the bottom of the support rod. The first sliding groove is fixed to both sides of the upper end of the support plate, and the sliding head slides in the first sliding groove and is located in the moving part. When the tray is used to transport fruits and vegetables normally, the pair of chains drive the support rod to move through the pair of crossbars, causing the support rod to move the tray. When the support rod moves, the sliding head at its bottom slides in the first sliding groove, thus preventing the support rod from rotating. When the sliding head moves into the moving part, a telescopic cylinder drives the moving part to move left and right, causing the moving part to rotate the sliding head, causing the fruits and vegetables in the tray to fall into the storage basket.

[0012] In one embodiment of this utility model, each end of the pair of crossbars is fixed with a rotating head, which rotates on a chain. The pair of crossbars rotate between the pair of chains via the rotating heads.

[0013] In one embodiment of this utility model, a fixed shaft is fixed between the pair of crossbars, and the support rod rotates on the fixed shaft. The pair of crossbars are fixedly connected by the fixed shaft, and the support rod rotates between the pair of crossbars by rotating on the fixed shaft.

[0014] In one embodiment of this utility model, a pair of pulleys are installed on both sides of the sliding head to reduce the friction of the sliding head sliding in the first groove.

[0015] In one embodiment of this utility model, a pair of slide rails are fixed inside the movable groove, and a pair of second slide grooves are chiseled on the bottom of the movable member, the second slide grooves sliding on the slide rails. The movable member slides on the slide rails through the second slide grooves, thereby sliding in the movable groove.

[0016] In one embodiment of this utility model, extension rods are fixed on both side walls of the movable member, and a pair of extension rods are respectively disposed on both sides of the support rod. When the movable member moves left or right, the pair of extension rods push the support rod, thereby causing the support rod to rotate.

[0017] In one embodiment of this utility model, rollers are slidably provided on each pair of extension rods to reduce the friction when the extension rods push the support rods.

[0018] In one embodiment of this utility model, a fixing member is fixed between the telescopic cylinder and the support plate, and the telescopic cylinder is fixed to the support plate by the fixing member.

[0019] Compared with existing technologies, the present invention provides a fruit and vegetable screening device based on AI vision, which effectively improves the screening efficiency of fruits and vegetables and reduces the labor intensity of operators through relevant structural design.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figures 1 to 6 As shown, an AI vision-based fruit and vegetable sieving device according to one embodiment of the present invention includes: a support frame 1, a pair of rotating shafts 103, a pair of chains 105, multiple mounting components 106, a mounting frame 101, multiple pairs of storage baskets 108, and multiple pushing mechanisms 2.

[0031] like Figures 1 to 6As shown, a support plate 117 is fixed inside the support frame 1. A pair of rotating shafts 103 rotate within the support frame 1 and are respectively located at both ends of the support plate 117. Each pair of rotating shafts 103 is equipped with a pair of chain teeth 104. A pair of chains 105 rotate on the pair of chain teeth 104 respectively. Multiple mounting components 106 are mounted between the pair of chains 105, and a tray 107 is mounted on the upper end of the mounting components 106. A mounting frame 101 is mounted on the support frame 1, and a vision scanner 102 is mounted on the mounting frame 101. Multiple pairs of storage baskets 108 are respectively mounted on the two side walls of the support frame 1. Multiple pushing mechanisms 2 are mounted on the support plate 117 and are respectively located between each pair of storage baskets 108. The pushing mechanism 2 includes: a moving groove 201, a moving part 202, and a telescopic cylinder 207. The moving groove 201 is carved into the support plate 117 and is located between a pair of storage baskets 108. The movable component 202 slides in the movable groove 201, and the bottom end of the mounting assembly 106 is located in the movable component 202. The telescopic cylinder 207 is installed on one side of the support plate 117, and a telescopic rod 208 is connected between the telescopic cylinder 207 and the movable component 202.

[0032] Before using this device, one of the rotating shafts 103 needs to be connected to an external drive unit to rotate it. During use, the fruits and vegetables to be screened are conveyed one by one by a conveyor belt into a tray 107 near one end of the mounting frame 101. Then, the rotating shaft 103 drives a pair of chain teeth 104 to rotate, which in turn drives a pair of chains 105 to rotate. The chains 105 then move the tray 107 via the mounting assembly 106. As the tray 107 passes through the mounting frame 101, the visual scanner 102 identifies the fruits and vegetables in the tray 107 to confirm their classification. Then, the chain 105 continues to move the tray 107. When it moves to the moving part 202, if the fruit or vegetable belongs to the classification at the moving part 202, the telescopic cylinder 207 controls the telescopic rod 208 to extend and retract. The telescopic cylinder 207 drives the moving part 202 to move left and right. The moving part 202 causes the tray 107 to rotate through the mounting component 106, so that the fruits and vegetables in the telescopic cylinder 207 are classified into the storage basket 108 on one side.

[0033] like Figures 1 to 6As shown, a pair of C-shaped clips 115 are fixed to the storage basket 108, and both C-shaped clips 115 are clipped onto the side wall of the support frame 1. The storage basket 108 is clipped onto the side wall of the support frame 1 by the pair of C-shaped clips 115. The mounting assembly 106 includes: a pair of crossbars 109, a support rod 112, and a first slide groove 116. The pair of crossbars 109 rotate between a pair of chains 105, and the pair of crossbars 109 are fixedly connected. The support rod 112 rotates between the pair of crossbars 109, the tray 107 is fixed to the top of the support rod 112, and a sliding head 113 is fixed to the bottom of the support rod 112. The first slide groove 116 is fixed to both sides of the upper end of the support plate 117, and the sliding head 113 slides in the first slide groove 116 and is located in the moving part 202. When the tray 107 is used to transport fruits and vegetables normally, a pair of chains 105 drive the support rod 112 to move through a pair of crossbars 109, so that the support rod 112 drives the tray 107 to move. When the support rod 112 moves, it slides in the first groove 116 through the sliding head 113 at its bottom end, thereby preventing the support rod 112 from rotating. When the sliding head 113 moves into the moving part 202, the telescopic cylinder 207 drives the moving part 202 to move left and right, so that the moving part 202 drives the sliding head 113 to rotate, causing the fruits and vegetables in the tray 107 to fall into the storage basket 108.

[0034] like Figures 1 to 6 As shown, a pair of crossbars 109 are each fixed to a rotating head 110, which rotates on a chain 105. The pair of crossbars 109 rotate between the pair of chains 105 via the rotating heads 110. A fixed shaft 111 is fixed between the pair of crossbars 109, and a support rod 112 rotates on the fixed shaft 111. The pair of crossbars 109 are fixedly connected by the fixed shaft 111, and the support rod 112 rotates between the pair of crossbars 109 by rotating on the fixed shaft 111. A pair of pulleys 114 are installed on both sides of the sliding head 113. The pulleys 114 on both sides of the sliding head 113 reduce the friction of the sliding head 113 sliding in the first groove 116.

[0035] like Figures 1 to 6As shown, a pair of slide rails 203 are fixed inside the moving groove 201. A pair of second slide grooves 204 are carved into the bottom of the moving part 202, and the second slide grooves 204 slide on the slide rails 203. The moving part 202 slides on the slide rails 203 through the second slide grooves 204, thereby sliding in the moving groove 201. Extension rods 205 are fixed on both sides of the moving part 202, and a pair of extension rods 205 are respectively provided on both sides of the support rod 112. When the moving part 202 moves left and right, it pushes the support rod 112 through the pair of extension rods 205, thereby causing the support rod 112 to rotate. Rollers 206 are slidably provided on each pair of extension rods 205, and the pair of rollers 206 reduce the friction when the extension rods 205 push the support rod 112. A fixing member 209 is fixed between the telescopic cylinder 207 and the support plate 117, and the telescopic cylinder 207 is fixed to the support plate 117 through the fixing member 209.

[0036] Working Principle: Before using this device, one of the rotating shafts 103 needs to be connected to an external drive unit to rotate it. During operation, the fruits and vegetables to be screened are conveyed one by one by a conveyor belt into a tray 107 near one end of the mounting frame 101. Then, the rotating shaft 103 drives a pair of chain teeth 104 to rotate, which in turn drives a pair of chains 105. The chains 105, through a pair of crossbars 109, move a support rod 112, which in turn moves the tray 107. As the tray 107 passes through the mounting frame 101, a vision scanner 102 visually identifies the fruits and vegetables in the tray 107, confirming their classification.

[0037] Subsequently, chain 105 continues to move tray 107. When 213 moves into moving part 202, if the fruit or vegetable belongs to the category at moving part 202, telescopic cylinder 207 controls telescopic rod 208 to extend or retract. Telescopic cylinder 207 drives moving part 202 to move left and right. Moving part 202 rotates support rod 112 via a pair of rollers 206. Support rod 112 drives tray 107 to rotate, causing the fruit or vegetable in telescopic cylinder 207 to be sorted into storage basket 108 on one side. After the fruit or vegetable is placed, moving part 202 drives support rod 112 to rotate, turning tray 107 to a horizontal position. Then chain 105 continues to drive tray 107 to move in a cycle.
