Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-4 This utility model provides a weight-based multi-stage fruit and vegetable sorting machine, including a conveyor table 1 and a support leg 2. The support leg 2 is fixedly installed at the bottom of the conveyor table 1. A feeding mechanism 3 is provided on the upper right side of the conveyor table 1 for guiding and conveying fruits and vegetables. A sorting mechanism 4 is provided on the left side of the feeding mechanism 3 for sorting by weight. A receiving device 5 is provided on the left side of the conveyor table 1 and matched with the sorting mechanism 4 for collecting the unloaded material.

[0026] The sorting mechanism 4 includes a conveying component 41 and a sorting component 42. The conveying component 41 is fixedly installed on the top of the conveying platform 1 and is used for classified conveying. The sorting component 42 is located on the upper part of the conveying component 41 and is used for conveying and sorting according to weight.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the feeding mechanism 3 includes a feeding frame 301, which is fixedly installed on the top right side of the conveyor table 1. A guide plate 302 is provided inside the feeding frame 301. An opening is opened at the bottom of the feeding frame 301 through the guide plate 302 in the rear left part of the feeding frame 301. An installation plate 303 is fixedly connected to the opening inside the feeding frame 301. A limiting band 304 is installed on the installation plate 303. The limiting band 304 is made of a flexible material with elasticity and is matched to the opening inside the feeding frame 301.

[0028] In use, the fruits and vegetables to be sorted are guided into the feed frame 301. Guided by the guide plate 302, the fruits and vegetables are guided to the left rear opening of the feed frame 301. The limiting belt 304 can buffer the guided fruits and vegetables. Through the opening, the fruits and vegetables enter in a single row through the limiting belt 304 and fall on the upper part of the conveyor table 1 for conveying.

[0029] As can be seen from the above working process, the feeding mechanism 3, in conjunction with the sorting mechanism 4, can perform stable positional conveying of the sorted fruits and vegetables, keeping them in a uniform conveying position. This facilitates weight-based sorting of the fruits and vegetables by the sorting mechanism 4, thereby improving the efficiency of fruit and vegetable sorting.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the conveying assembly 41 includes a conveying frame 411, which is fixedly connected to the top of the conveying platform 1 and located on the left side of the feed frame 301. A baffle 413 is fixedly connected inside the conveying frame 411. A protective plate 412 is fixedly connected to the front of the conveying frame 411 at the top of the conveying platform 1. The right side of the conveying frame 411 is obliquely arranged and matches the material distribution assembly 42. Multiple baffles 413 are provided inside the conveying frame 411, and the multiple baffles 413 are evenly spaced inside the conveying frame 411.

[0031] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the material distribution assembly 42 includes a U-shaped frame 421, which is fixedly connected to the top of the conveyor frame 411. A weighing block 422 is detachably and slidably arranged inside the U-shaped frame 421. The U-shaped frame 421 is configured as a boss-shaped slide block. The weighing block 422 slides inside the U-shaped frame 421 by gravity. A sliding rod 423 is provided at the front of the weighing block 422. The sliding rod 423 is slidably arranged on the U-shaped frame 421. A slider 424 is fixedly connected to the front of the sliding rod 423. The bottom of the slider 424 is fixedly... A connecting plate 426 is fixedly connected to the conveyor frame 411. A matching slide groove 425 is provided on the slide groove 425. A limiting groove 427 matching the connecting plate 426 is provided on the lower part of the slide groove 425 inside the conveyor frame 411. A reset rotating shaft 428 is fixedly installed on one end of the connecting plate 426 near the rear. A movable plate 429 is rotatably installed on the bottom end of the reset rotating shaft 428. A stop block 4210 is provided on one side of the front part of the movable plate 429. The stop block 4210 is fixedly connected to the baffle 413 inside the conveyor frame 411.

[0032] The weighing blocks 422 are configured according to weight gradients: for example, three levels of 50g, 100g, and 150g (which can be replaced), arranged along the U-shaped frame 421 from back to front with decreasing weight; the reset shaft 428 has a built-in torsion spring to ensure that the movable plate 429 automatically resets within 0.2 seconds after the fruits and vegetables pass through.

[0033] In use, different weights of weighing blocks 422 are slidably installed inside the U-shaped frame 421, with the weight decreasing from back to front. When fruits and vegetables are conveyed through the conveyor table 1, based on their weight, when the fruits and vegetables contact the movable plate 429, the stop block 4210 prevents it from rotating, thereby causing the connecting plate 426 and the slider 424 to slide within the slide groove 425 and the limiting groove 427, respectively. When the weight of the conveyed fruits and vegetables exceeds the weight of the U-shaped frame 421 at this point... When the weight of the internally installed weighing block 422 is measured, the sliding of the slider 424 pushes the sliding rod 423, causing the weighing block 422 to slide within the U-shaped frame 421. This causes the movable plate 429 to disengage from the stop block 4210, and then the movable plate 429 rotates through the reset shaft 428. This allows the fruits and vegetables to be conveyed into the conveying frame 411 through the opening of the movable plate 429. The sorted fruits and vegetables are then transported by the baffle 413 and, through the matching setting of the partition 502, are easily sorted and collected.

[0034] Further as Figure 1 and Figure 2 As shown, it is worth noting that the receiving device 5 includes a material distribution frame 501 and multiple partitions 502. The material distribution frame 501 is fixedly installed on the left side of the conveyor table 1, and the multiple partitions 502 are fixedly installed on the upper part of the material distribution frame 501 and are matched with the baffle 413.

[0035] This solution has the following working process: When this device is used, the fruits and vegetables to be sorted are guided into the feed frame 301. Guided by the guide plate 302, the fruits and vegetables are guided to the left rear opening inside the feed frame 301. The limiting belt 304 provides buffering for the guided fruits and vegetables. Through the opening, the fruits and vegetables fall onto the upper part of the conveyor table 1 for transport, and are obliquely transported to the right rear side of the corresponding conveyor frame 411. At this time, weighing blocks 422 of different weights are sequentially slidably installed inside the U-shaped frame 421, with the weight decreasing from back to front. When the fruits and vegetables are transported through the conveyor table 1, based on their weight, when the fruits and vegetables contact the movable plate 429, the abutment block 4210 prevents the abutment block 4210 from rotating, thereby causing the connecting plate 426 and the slider 424 to slide within the sliding groove 425 and the limiting groove 427 respectively. When the weight of the fruits and vegetables being transported exceeds the weight of the weighing block 422 installed inside the U-shaped frame 421, the sliding of the slider 424 pushes the sliding rod 423, causing the weighing block 422 to slide within the U-shaped frame 421. This causes the movable plate 429 to disengage from the stop block 4210, and the movable plate 429 to rotate via the reset shaft 428. This allows the fruits and vegetables to be transported into the conveying frame 411 through the opening of the movable plate 429. The sorted fruits and vegetables are then transported by the baffle 413 and the matching arrangement of the partition 502 facilitates sorting and collection. During the transport of fruits and vegetables, the reset shaft 428 resets the movable plate 429, and the gravity of the weighing block 422 pushes the sliding rod 423, which in turn drives the slider 424, causing the movable plate 429 to return to its original position on the right side of the conveying frame 411, thus facilitating the transport of fruits and vegetables.

[0036] In summary: the feeding mechanism 3, in conjunction with the sorting mechanism 4, enables stable positional conveying of sorted fruits and vegetables, maintaining a uniform conveying position. This facilitates weight-based sorting of fruits and vegetables by the sorting mechanism 4, improving sorting efficiency. Furthermore, the sorting mechanism 4, based on the conveying operation of the conveyor table 1, enables sorting of fruits and vegetables of different weights, allowing for independent conveying and sorting based on weight, thus improving conveying stability.
