Description
Technical Field
[0001] The present invention relates to the technical field of fruit and vegetable sorting, and in particular to a fruit basket turning and conveying device for fruit and vegetable sorting. Background Art
[0002] With the continuous advancement of agricultural technology and consumers' increasing demands for fruit and vegetable quality, fruit and vegetable sorting has become a critical link in ensuring market supply. The fruit basket turning and conveying device plays a crucial role in the fruit and vegetable sorting process. It is responsible for smoothly turning the filled fruit and vegetable baskets so that the fruits and vegetables can fall smoothly and undamaged onto the sorting machine's conveyor belt, completing quality and size grading.
[0003] However, traditional fruit basket turning devices often adopt a simple tilting method during the turning process, causing fruits and vegetables to be directly and quickly poured out under the action of gravity. This uncontrolled pouring method causes fruits and vegetables to accumulate a large amount of energy when they freely fall in the air, and eventually hit the conveyor belt or sorting equipment, which can easily cause surface damage to the fruits and vegetables. This not only affects the appearance of the fruits and vegetables, but may also shorten their shelf life and cause economic losses.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This invention utilizes the coordinated design of a rotating structure, a rotatable conveying structure, a fruit basket placement plate, a lifting plate, and a lifting structure. The lifting structure controls the basket's tilting angle, ensuring contact between the fruit and vegetable conveyor belt and the basket. A rotating motor then drives the shaft at a low speed, slowly rotating the basket 180 degrees, allowing the fruits and vegetables to naturally slide onto the conveyor belt under the influence of gravity. During this process, the sliding coordination of the guide post and the lifting plate ensures smooth lifting of the basket, completely resolving the problem of rapid tipping in conventional systems, which can lead to free fall and impact damage to fruits and vegetables, and significantly reducing the rate of mechanical damage to fruits and vegetables.
[0018] 2. This invention features several hemispherical airbags fixed to the surface of the fruit and vegetable conveyor belt. When the fruit basket flips and falls, the airbags elastically deform and absorb the impact energy, forming a flexible buffer layer. This design effectively disperses the localized pressure of falling fruits and vegetables, avoiding surface abrasions and internal pressure loss caused by traditional hard contact. This design not only improves the appearance and shelf life of fruits and vegetables, but also reduces the economic losses caused by damage.
[0019] 3. This invention uses a fruit basket recovery motor to drive the fruit basket recovery rollers and the fruit basket recovery conveyor belt. When the damage prevention basket turning mechanism rotates to 270 degrees, the empty fruit baskets are released from the clamping plate and fall onto the fruit basket recovery conveyor belt, which quickly transports the empty baskets to a designated area. This fruit basket recovery mechanism completely replaces manual recovery operations, solving the inefficiency caused by traditional systems relying on manual intervention and significantly improving the overall efficiency of the sorting process.

[0034] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.
[0035] The present invention provides a technical solution:
[0036] See also Figures 1 to 8 A fruit basket flipping and conveying device for sorting fruits and vegetables includes a fruit basket recovery workbench 1, a fruit basket recovery and conveying mechanism 2 is fixedly installed on the top of the fruit basket recovery workbench 1, and an anti-damage flipping basket mechanism 3 is provided on the top of the fruit basket recovery workbench 1 and is located directly above the fruit basket recovery and conveying mechanism 2.
[0037] The anti-damage basket turning mechanism 3 includes a bracket 301 symmetrically mounted on the top of the fruit basket recovery workbench 1, a bearing 302 fixedly mounted on the bracket 301, and a rotating structure 303 rotatably connected to the bearing 302; a rotatable conveying structure 304 is symmetrically mounted on the outer side of the rotating structure 303, and the number of rotatable conveying structures 304 is two, and a plurality of hemispherical column air bags 305 are fixedly mounted on the outer side of the rotatable conveying structure 304; guide pillars 305 are fixedly mounted at the four corners of the rotatable conveying structure 304 06, there are four guide pillars 306, and a fruit basket placement plate 307 is fixedly installed at one end of the four guide pillars 306 away from the rotatable conveying structure 304. A lifting plate 308 is provided on the fruit basket placement plate 307, which is slidably connected to the guide pillars 306. Electric cylinders 309 are symmetrically installed on the lifting plate 308. A clamping plate 310 is fixedly installed at the output end of the electric cylinder 309. A fruit basket 311 is provided on the inner side of the clamping plate 310, and a lifting structure 312 is provided on the outer side of the fruit basket placement plate 307.
[0038] During operation, the fruit basket 311 is placed on the fruit basket placement plate 307 and clamped in place by the clamping plate 310 driven by the electric cylinder 309. The lifting motor 3123 in the lifting mechanism 312 rotates the screw 3122, causing the ball screw 3124 to drive the lifting plate 308 upward along the guide post 306, lifting the fruit basket 311 to a position where it contacts the rotatable conveyor structure 304. At this point, the rotating mechanism 303, driven by the rotating motor 3034, slowly rotates 180 degrees, causing the rotatable conveyor structure 304 and the fruit basket 311 to flip together. Gravity allows the fruits and vegetables in the fruit basket 311 to naturally slide onto the fruit and vegetable conveyor belt 3044 of the rotatable conveyor structure 304. The hemispherical airbag 305 acts as a cushion during the falling of the fruits and vegetables, effectively reducing mechanical impact and surface damage. After the flip is complete, the lifting plate 308 descends, releasing the fruit basket 311 and dropping it onto the fruit basket recovery mechanism 2 for automatic recovery. During the entire process, the anti-damage basket turning mechanism 3 achieves smooth turning of the fruit basket and lossless transportation of fruits and vegetables through its unique structure, which significantly improves the efficiency and quality of fruit and vegetable sorting.
[0039] See also Figure 1 、 Figure 4 and Figure 6 The rotating structure 303 includes a cross connecting frame 3031 fixedly mounted on the inner surface of the bearing 302, and a shaft 3032 is fixedly mounted on the inner wall of the cross connecting frame 3031. The shaft 3032 passes through the two brackets 301, and a rectangular bar 3033 adapted to the shaft 3032 is fixedly mounted on the outer side of the shaft 3032. The rectangular bar 3033 is located on the inner side of the two brackets 301, and the rectangular bar 3033 is fixedly connected to the rotatable conveying structure 304. A rotating motor 3034 fixedly connected to the bracket 301 is fixedly mounted on one end of the shaft 3032, and the output end of the rotating motor 3034 is fixedly connected to the shaft 3032.
[0040] During operation, the rotating motor 3034 starts, slowly rotating the shaft 3032. The rotational motion of the shaft 3032 is transmitted to the rotatable conveying structure 304 via the rectangular bar 3033, causing it to flip as the rotating structure 303 rotates. During this process, the rotatable conveying structure 304 slowly rotates the fruit basket 311 180 degrees, allowing the fruits and vegetables in the fruit basket 311 to naturally slide down the fruit and vegetable conveyor belt 3044 of the rotatable conveying structure 304 under the action of gravity. The cooperation between the cross-connecting frame 3031 and the bearing 302 of the rotating structure 303 ensures smooth and stable flipping, avoiding the free fall and impact damage of fruits and vegetables caused by rapid tipping in conventional devices. Furthermore, the rotating motor 3034 can adjust the rotation speed and angle as needed to ensure accurate and adaptable flipping of the fruit basket 311. The entire rotating structure 303 has a compact and rational design, occupies a small space, and is easy to integrate and install into the fruit and vegetable sorting equipment, significantly improving the overall efficiency and reliability of the equipment.
[0041] See also Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The rotatable conveying structure 304 includes a rotatable frame 3041 symmetrically mounted on the outside of the rectangular bar 3033. Two fruit and vegetable conveying rollers 3042 rotate inside the rotatable frame 3041. A fruit and vegetable conveying motor 3043 is fixedly mounted on one end of one of the fruit and vegetable conveying rollers 3042. The fruit and vegetable conveying motor 3043 is fixedly connected to the rotatable frame 3041. The outer side of the fruit and vegetable conveying roller 3042 is transmission-connected to a fruit and vegetable conveyor belt 3044; a number of hemispherical airbags 305 are fixedly mounted on the fruit and vegetable conveyor belt 3044; the rotatable frame 3041 is fixedly connected to the guide column 306.
[0042] During operation, the fruit and vegetable conveyor motor 3043 is activated, driving one of the fruit and vegetable conveyor rollers 3042 to rotate. This, in turn, drives the other fruit and vegetable conveyor roller 3042 and the fruit and vegetable conveyor belt 3044 through a transmission connection. As the rotating structure 303 slowly rotates the rotatable conveying structure 304, the fruits and vegetables in the fruit basket 311 naturally slide onto the fruit and vegetable conveyor belt 3044 under the action of gravity. At this point, the hemispherical airbags 305 act as a cushion during the fruit and vegetable's fall. Their elastic deformation absorbs impact energy, forming a flexible buffer layer that effectively distributes the localized pressure of the falling fruit and vegetables, preventing surface abrasions and internal pressure loss caused by traditional rigid contact. The fruit and vegetable conveyor belt 3044 then smoothly transports the fruits and vegetables to the designated location. Throughout this process, the rotatable conveying structure 304, through its unique structure, power drive, and buffering design, ensures smooth conveyance and flexible cushioning of the fruits and vegetables, significantly improving their appearance and shelf life, while also enhancing the efficiency and quality of fruit and vegetable sorting.
[0043] See also Figure 1 、 Figure 5 、 Figure 6 and Figure 8 The lifting structure 312 includes a screw mounting frame 3121 fixedly mounted on the outside of the fruit basket placement plate 307. The screw mounting frame 3121 is composed of a mounting plate and a gantry frame, wherein the mounting plate is fixedly connected to the fruit basket placement plate 307, and the gantry frame is fixedly mounted on the mounting plate. A screw 3122 is rotatably connected to the screw mounting frame 3121, and a lifting motor 3123 fixedly connected to the screw mounting frame 3121 is fixedly mounted on one end of the screw 3122. The output end of the lifting motor 3123 is fixedly connected to the screw 3122. A ball screw block 3124 is threadedly connected to the screw 3122, and the ball screw block 3124 is fixedly connected to the lifting plate 308.
[0044] When the fruit basket 311 needs to be lifted, the lifting motor 3123 is activated, driving the screw 3122 to rotate. The rotational motion of the screw 3122 is converted into linear upward motion by the ball screw 3124 into the lifting plate 308. The lifting plate 308 then slides upward along the guide posts 306, lifting the fruit basket 311 until it contacts the rotatable conveying structure 304. During this process, four guide posts 306 are mounted at the four corners of the rotatable conveying structure 304 to ensure smooth lifting and lowering of the lifting plate 308. The sliding connection between the lifting plate 308 and the guide posts 306 further ensures stability during the lifting process. The lifting structure 312 ensures smooth and precise lifting and lowering of the fruit basket 311, providing strong support for the rotation and conveying of fruits and vegetables. Furthermore, the lifting structure 312 is fully automated, requiring no human intervention and improving work efficiency. Its mechanical transmission system is simple, reliable, and easy to maintain, ensuring efficient and stable operation of the fruit basket rotation and conveying device for fruit and vegetable sorting.
[0045] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The fruit basket recovery and conveying mechanism 2 includes fruit basket recovery supports 201 fixedly installed at the four corners of the top of the fruit basket recovery workbench 1. There are four fruit basket recovery supports 201. The inner sides of the two fruit basket recovery supports 201 are rotatably connected to two fruit basket recovery conveying rollers 202. One end of one of the fruit basket recovery conveying rollers 202 is fixedly installed with a fruit basket recovery motor 203. The fruit basket recovery motor 203 is fixedly installed on the fruit basket recovery support 201. The outer side of the fruit basket recovery conveying roller 202 is transmission-connected to a fruit basket recovery conveyor belt 204.
[0046] When the anti-damage basket turning mechanism 3 rotates to a certain angle (such as 270 degrees), the empty fruit basket 311 naturally falls onto the fruit basket recovery conveyor belt 204 under the action of gravity. At this time, the fruit basket recovery motor 203 starts, driving the fruit basket recovery conveyor roller 202 to rotate, and then driving the fruit basket recovery conveyor belt 204 to operate. During the operation of the fruit basket recovery conveyor belt 204, the empty fruit basket 311 is smoothly and quickly transported to the designated collection area, realizing the automatic recovery and recycling of the fruit basket. Throughout the entire process, the fruit basket recovery conveying mechanism 2 realizes the automatic recovery and transportation of the empty fruit baskets without the need for manual intervention, greatly improving work efficiency. At the same time, the design of the fruit basket recovery conveying mechanism 2 is compact and reasonable, occupies little space, and is easy to integrate and install in the fruit and vegetable sorting equipment, providing an efficient and lossless solution for fruit and vegetable sorting operations.
[0047] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5, guide rails 4 are symmetrically installed on the inner side of the bracket 301, and there are two guide rails 4. A fruit and vegetable transfer mechanism 5 is slidably connected to the inner side of the guide rails 4; the fruit and vegetable transfer mechanism 5 includes a fruit and vegetable transfer frame 501 slidably connected to the inner side of the guide rails 4, and two fruit and vegetable transfer conveying rollers 502 are rotatably connected to the inner side of the fruit and vegetable transfer frame 501, one end of which is fixedly installed with a fruit and vegetable transfer motor 503, and the fruit and vegetable transfer motor 503 is fixedly connected to the fruit and vegetable transfer frame 501, and the outer side of the fruit and vegetable transfer conveying roller 502 is transmission-connected with a fruit and vegetable transfer conveyor belt 504, and a fruit and vegetable transfer support frame 505 is fixedly installed at the bottom of the fruit and vegetable transfer frame 501, and a roller 506 is fixedly installed at the bottom of the fruit and vegetable transfer support frame 505.
[0048] The fruit and vegetable transfer motor 503 is started, driving one of the fruit and vegetable transfer conveyor rollers 502 to rotate, thereby driving the fruit and vegetable transfer conveyor belt 504 to operate. When the anti-damage basket turning mechanism 3 flips the fruit basket 311 to a certain angle, the fruits and vegetables in the fruit basket 311 naturally slide onto the fruit and vegetable transfer conveyor belt 504 under the action of gravity. At this time, the fruit and vegetable transfer conveyor belt 504 smoothly transports the fruits and vegetables to the designated position, making it convenient for the fruits and vegetables to undergo the next sorting task. During the entire process, the fruit and vegetable transfer rack 501 is slidably connected to the guide rail 4 on the inner side of the bracket 301 to achieve horizontal movement, which is convenient for docking with the fruit and vegetable conveyor belt 3044. At the same time, the design of the electric telescopic rod 507 allows the gap between the fruit and vegetable transfer conveyor belt 504 and the fruit and vegetable conveyor belt 3044 to be adjusted as needed to ensure the smooth transfer of fruits and vegetables.
[0049] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The fruit and vegetable transport mechanism 5 also includes an electric telescopic rod 507 rotatably connected to the fruit and vegetable transport support frame 505 , and the other end of the electric telescopic rod 507 is rotatably connected to the fruit basket recovery workbench 1 .
[0050] During the fruit and vegetable sorting process, when the damage prevention basket-turning mechanism 3 flips the fruit basket 311 to a certain angle, the fruits and vegetables in the fruit basket 311 naturally slide onto the fruit and vegetable transfer conveyor belt 504 under the action of gravity. At this time, the electric telescopic rod 507 adjusts the gap between the fruit and vegetable transfer conveyor belt 504 and the fruit and vegetable conveyor belt 3044 through telescopic movement, ensuring that the two are seamlessly connected. This control not only improves the efficiency of the entire transfer process, but also reduces manual intervention, significantly improving the flexibility and versatility of the equipment. Through the adjustment of the electric telescopic rod 507, the fruits and vegetables can maintain a smooth and continuous flow during the transfer process, effectively preventing leakage and damage to the fruits and vegetables, and improving the safety and quality of the sorting process.
[0051] In some embodiments, anti-spill plates are fixedly installed on the rotatable frame 3041 and the fruit and vegetable transfer frame 501.
[0052] In this embodiment, the anti-spill plate can reduce the possibility of fruits and vegetables sliding off the fruit and vegetable conveyor belt 3044 and the fruit and vegetable transfer conveyor belt 504 during transportation and transfer.
[0053] When used specifically, the working principle of the present invention is as follows:
[0054] When using this device, a robotic arm or other transfer device is first used to precisely place the fruit basket 311 on the fruit basket placement plate 307, ensuring that the fruit basket 311 is positioned correctly. Subsequently, an electric cylinder 309 drives the clamping plates 310 to move, firmly clamping both sides of the fruit basket 311 to prevent it from shaking during subsequent operations. The clamping force of the clamping plates 310 must be controlled to prevent deformation of the fruit basket or damage to the fruits and vegetables from pressure.
[0055] Once the fruit basket 311 is clamped and secured, the lifting mechanism 312 begins operating. The lifting motor 3123 slowly rotates the screw 3122, causing the ball screw 3124 to rise steadily along the screw 3122, thereby pushing the lifting plate 308 toward the rotatable conveying mechanism 304. During this process, the fruit basket 311 must remain balanced. When the open top of the fruit basket 311 comes into close contact with the hemispherical airbag 305 on the fruit and vegetable conveyor belt 3044, the lifting motor 3123 stops operating. At this point, the fruit basket 311 is at the optimal tilting angle, and the soft surface of the hemispherical airbag 305 fits perfectly against the edge of the fruit basket 311, further reducing the mechanical impact of the fruit and vegetables during tilting.
[0056] Next, the rotating motor 3034 rotates at a low speed under the action of the bearing 302, driving the shaft 3032 to slowly rotate 180 degrees. During the slow rotation process, the fruits and vegetables are ensured to slide naturally under the action of gravity, rather than being thrown by inertia. This slow and steady rotation method significantly reduces the collision energy between fruits and vegetables, effectively avoiding surface abrasions and internal damage. In the initial state, an appropriate gap is maintained between the fruit and vegetable transfer conveyor belt 504 and the fruit and vegetable conveyor belt 3044, providing sufficient space for the rotation process and preventing interference between the fruit and vegetable conveyor belt 3044 and the fruit and vegetable transfer conveyor belt 504 during rotation.
[0057] After completing the 180-degree rotation, the electric telescopic rod 507 slowly shortens, pulling the fruit and vegetable transfer support frame 505 to move smoothly, gradually narrowing the gap between the fruit and vegetable transfer conveyor belt 504 and the fruit and vegetable conveyor belt 3044. This prevents the fruit and vegetables from leaking out of the gap. At this point, the lifting motor 3123 is controlled to rotate in the opposite direction, driving the lifting plate 308 to slowly move, emptying the fruit and vegetables in the fruit basket 311 onto the hemispherical airbag 305 on the fruit and vegetable conveyor belt 3044.
[0058] When all the fruits and vegetables have fallen onto the fruit and vegetable conveyor belt 3044, the fruit and vegetable conveyor motor 3043 immediately starts, driving the fruit and vegetable conveyor belt 3044 to rotate at a constant speed, smoothly conveying the fruits and vegetables to the fruit and vegetable transfer conveyor belt 504. The fruit and vegetable transfer motor 503 rotates the fruit and vegetable transfer conveyor roller 502, which in turn drives the fruit and vegetable transfer conveyor belt 504, moving the fruits and vegetables to the designated sorting equipment. The fruit and vegetable conveyor belt 3044 and the fruit and vegetable transfer conveyor belt 504 maintain a seamless connection, ensuring that the fruits and vegetables do not need to stop during the transfer process, significantly improving sorting efficiency. When all the fruits and vegetables have been transferred, the electric telescopic rod 507 extends, returning the fruit and vegetable transfer conveyor belt 504 to its original position, ready for the next flipping operation.
[0059] Finally, when the rotary motor 3034 rotates to 270 degrees, the electric cylinder 309 controls the release of the clamping plate 310, and the fruit basket 311 naturally falls onto the fruit basket recovery conveyor belt 204 under the action of gravity. The fruit basket recovery motor 203 then starts, driving the fruit basket recovery conveyor roller 202 to rotate. The fruit basket recovery conveyor belt 204 rotates, transporting the empty fruit baskets to the designated collection area. The entire recovery process requires no human intervention, achieving automatic recycling of the fruit baskets 311 and significantly improving work efficiency.
[0060] In summary, this device, through its integrated clamping, lifting and rotation, conveying and docking, and basket recovery processes, not only effectively reduces mechanical damage to fruits and vegetables during the turning process, but also significantly improves sorting efficiency and ease of operation.
