Description

Technical Field

[0001] This utility model relates to the field of lychee sorting technology, and in particular to a clamping and separating device for lychee sorting. Background Technology

[0002] Lychee sorting is a process of classifying and selecting lychees after harvesting based on their size, color, maturity, degree of appearance defects, and variety standards, using manual or mechanical equipment. The purpose is to group lychees of similar quality into one category, facilitating subsequent grading, sales, processing, or storage, thereby increasing the commercial value and market competitiveness of lychees and meeting the needs of different consumers.

[0003] The clamping and separating device for lychee sorting is a key component in the lychee sorting process. It mainly uses a mechanical clamping mechanism to gently grasp clusters or sticky lychees, and uses mechanical motion or separation elements to separate individual lychees. At the same time, sensors monitor the clamping force and separation status in real time to avoid damaging the fruit, achieving efficient and damage-free separation of individual lychees, providing a foundation for subsequent sorting processes. However, the magnetic suction interface of the modular quick-release clamp requires high-precision machining. Long-term use can lead to poor contact due to contamination by residue and juice, increasing maintenance costs. In existing technologies, the magnetic suction module is designed with a rotatable docking surface. Each time the module is disassembled, the outer ring is driven by a motor to rotate, and a flexible nylon brush is used to scrape off the residue on the magnetic suction surface. However, the fruit size difference of the unsorted fruit is significant. When it enters the same sorting channel directly, large and small fruits are not easy to sort on the conveyor belt, resulting in the inability to distinguish between large and small fruits, which has an adverse effect on subsequent packaging.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a lychee sorting and clamping separation device, including a conveyor body 1. A conveyor belt 7 is installed on the right side of the conveyor body 1. A screening mechanism 3 is installed on the top left side of the conveyor belt 7 for preliminary screening of lychees. An outlet mechanism 2 is installed on the bottom right side of the conveyor body 1 for outlet of lychees. The screening mechanism 3 includes a screening box 306, which is fixedly connected to the top left end of the conveyor belt 7. A rotating rod 303 is rotatably connected to the right side of the interior of the screening box 306. An inclined plate 301 is fixedly connected to the left side of the rotating rod 303. Multiple filter holes 304 are equidistantly opened on the top left side of the inclined plate 301. The filter holes 304 facilitate the screening of lychees. Springs 302 are fixedly connected to the front and rear ends of the bottom of the screening box 306. A cleaning component 305 is installed on the top of the screening box 306. The cleaning component 305 includes a cleaning box 3055. The cleaning box 3055 is fixedly connected to the top right side of the screening box 306. A second motor 3052 is installed on the front side of the cleaning box 3055. A connecting rod 3054 is fixedly connected to the output end of the second motor 3052. Multiple mixing blades 3053 are fixedly connected at equal intervals on the outer side of the connecting rod 3054. A connecting box 3051 is connected to the bottom of the cleaning box 3055. Multiple nozzles 3056 are installed at equal intervals on the left side of the connecting box 3051. The bottom of the spring 302 is fixedly connected to the inner bottom of the screening box 306. An installation rod 9 is installed on the bottom left side of the conveyor body 1.

[0032] Specifically, lychees are conveyed from conveyor body 1 to screening box 306. The rotating rod 303 inside screening box 306 drives the inclined plate 301 to rotate. Utilizing the filter holes 304 of different sizes on the inclined plate 301, smaller lychees fall through the filter holes 304 under the action of gravity. The spring 302 at the bottom of the inclined plate 301 ensures the stability of the screening process. At the same time, the starting of the second motor 3052 drives the connecting rod 3054 and the mixing blade 3053 to rotate, mixing the washing liquid. The mixed washing liquid is sprayed out through the connecting box 3051 and the nozzle 3056 to clean the lychees. After screening, larger lychees continue to be conveyed by conveyor belt 7, while smaller lychees are guided by the bottom of conveyor body 1 and fall into the discharge mechanism 2, achieving efficient collection of smaller lychees. Through the above process, the screening, cleaning and separation of lychees are completed.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The discharge mechanism 2 includes a collection box 201, which is installed on the bottom right side of the conveyor body 1. Connecting square plates 202 are fixedly connected to the rear sides of both the left and right ends of the collection box 201. Mounting square plates 203 are slidably connected to the front sides of both the left and right ends of the collection box 201. A threaded rod 204 is threadedly connected to the middle of the mounting square plate 203. The outer side of the threaded rod 204 is threadedly connected to the middle of the connecting square plate 202. A drive assembly 205 is installed on the rear side of the threaded rod 204. The drive assembly 205 includes a first motor 2051. 51 is set at the rear left end of the threaded rod 204. The output end of the first motor 2051 is fixedly connected to the connecting long round rod 2053. The installation of the first motor 2051 facilitates the operation of subsequent processes. The left and right ends of the connecting long round rod 2053 are fixedly connected to the driving bevel gear 2052. The rear sides of the two threaded rods 204 are fixedly connected to the driven bevel gear 2054. The rear side of the driven bevel gear 2054 meshes with the front side of the driving bevel gear 2052. The outer side of the mounting square plate 203 is fixedly connected to the bottom of the conveyor body 1.

[0034] Specifically, the first motor 2051 is started, and its output drives the connecting long cylindrical rod 2053 to rotate, thereby driving the active bevel gear 2052 at both ends of the connecting long cylindrical rod 2053 to rotate. Due to the meshing transmission between the active bevel gear 2052 and the driven bevel gear 2054, the threaded rod 204 rotates synchronously. When the threaded rod 204 rotates, it pushes the connecting square plate 202 to move, thereby driving the collection box 201 to move forward or backward. When the collection box 201 is full, it is moved forward to facilitate subsequent processing. Through the above process, the collection and export of smaller lychees are realized.

[0035] Reference Figure 1 , Figure 2 and Figure 3A mounting plate 6 is installed on the rear side of the conveyor belt 7, and multiple robotic arms 4 are installed at equal intervals on the front side of the mounting plate 6. Multiple first collection boxes 5 are set at equal intervals on the front side of the conveyor belt 7, and a second collection box 8 is installed at the bottom right end of the conveyor belt 7.

[0036] Specifically, the installation of robotic arm 4 facilitates the detailed sorting of lychees, and the installation of the first collection box 5 facilitates the collection of lychees.

[0037] Working principle: Lychees are conveyed from conveyor body 1 to screening box 306. Inside screening box 306, rotating rod 303 drives inclined plate 301 to rotate. Utilizing the size difference of filter holes 304 on inclined plate 301, smaller lychees fall through the filter holes 304 under the action of gravity. Spring 302 at the bottom of inclined plate 301 ensures stable screening. At the same time, second motor 3052 is turned on to drive connecting rod 3054 and mixing blade 3053 to rotate, mixing the washing liquid, which is then sprayed out through connecting box 3051 and nozzle 3056 to wash the lychees. Larger lychees after screening continue to be conveyed by conveyor belt 7, while smaller lychees are guided by the bottom of conveyor body 1 and fall into discharge mechanism 2, achieving efficient collection of smaller lychees. Through the above process, the screening, washing and separation of lychees are completed.

[0038] First, the first motor 2051 is turned on, and its output end drives the connecting long round rod 2053 to rotate, which in turn causes the driving bevel gears 2052 at both ends of the connecting long round rod 2053 to rotate. Since the driving bevel gears 2052 and the driven bevel gears 2054 mesh and transmit power, the threaded rod 204 rotates synchronously. When the threaded rod 204 rotates, the connecting square plate 202 moves, which in turn drives the collection box 201 to move forward or backward. When the collection box 201 is full, the collection box 201 moves forward, which facilitates subsequent processing. Through the above process, the collection and export of smaller lychees are realized.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
