One of the conveying belts 2 conveys multiple cans containing agricultural products into the main support 1, the multi-station positioning assembly 3 synchronously positions and fixes the multiple cans in the main support 1, and the other conveying belt 2 is placed with a box for containing the cans, the grabbing mechanism 4 synchronously grabs the multiple positioned cans and moves to place them into the box, so as to simultaneously feed and contain the cans; The grabbing mechanism 4 comprises a driving assembly 5, a clamping assembly 6 and a locking assembly 7, the clamping assembly 6 is matched on the driving assembly 5, the clamping assembly 6 comprises a plurality of connecting seats 611, upper clamping plates 62 and lower clamping plates 63, the upper clamping plates 62 are rotatably installed on two sides of each connecting seat 611, and the lower clamping plates 63 are connected below each upper clamping plate 62 through slide rods 631; When the cans are grabbed, the driving assembly 5 drives the clamping assembly 6 to move above the positioned cans, the clamping assembly 6 synchronously drives the upper clamping plates 62 on the connecting seats 611 to drive the lower clamping plates 63 to combine, and meanwhile, the cans are clamped, the locking assembly 7 comprises a locking rod 71, the locking rod 71 is arranged in the upper clamping plate 62 and located at one side of the slide rod 631, and one end of the locking rod 71 extends from the inner side of the upper clamping plate 62, when the cans are clamped, the combined upper clamping plates 62 push the extending locking rod 71 into the opposite upper clamping plate 62, so that the locking rod 71 locks the slide rod 631.

[0022] In use, the conveying belts 2 on both sides of the main support 1 rotate in the same direction and start conveying the cans and boxes to their output ends respectively. When the first box is conveyed to the position for loading cans, the conveying belt 2 for conveying the boxes stops rotating and waits for loading cans, while the conveying belt 2 for conveying the cans continues to operate. The multi-position positioning assembly 3 on the conveying belt 2 positions the cans conveyed one by one in the position for grasping, waiting for the grasping mechanism 4 to grasp. When the multi-position positioning assembly 3 positions several cans, the driving assembly 5 drives the clamping assembly 6 initially located above the multi-position positioning assembly 3 to move downward and approach the positioned cans. At this time, the upper clamping plates 62 and the lower clamping plates 63 on both sides of the connecting seat 611 are in an open state, and the lower clamping plates 63 naturally drop to the lowest end. With the descent of the clamping assembly 6, the open upper clamping plates 62 and the lower clamping plates 63 cover the cans. The lower clamping plates 63 slide down along the bottle body until they come into contact with the upper side of the multi-position positioning assembly 3. After that, the upper clamping plates 62 continue to move downward and approach the upper clamping plates 62. The sliding rods 631 on the lower clamping plates 63 move upward in the upper clamping plates 62. When the top inside of the upper clamping plates 62 comes into contact with the upper end of the cans, the clamping assembly 6 stops moving downward and makes the upper clamping plates 62 on both ends of the connecting seat 611 combine with the lower clamping plates 63 below to clamp the cans. In this process, the upper clamping plates 62 on both sides of the connecting seat 611 push the locking rods 71 protruding from the opposite upper clamping plates 62 into the upper clamping plates 62, so that the locking rods 71 lock the sliding rods 631, preventing the sliding rods 631 from moving on the upper clamping plates 62, and fixing the position of the lower clamping plates 63 on the bottle body of the cans. Then the driving assembly 5 starts to lift the clamping assembly 6. Under the cooperation of the upper end of the cans clamped by the upper clamping plates 62 and the bottle body of the cans clamped by the lower clamping plates 63, several cans positioned by the multi-position positioning assembly 3 are lifted by the clamping assembly 6 and separated from the multi-position positioning assembly 3. After the cans are separated from the multi-position positioning assembly 3, the driving assembly 5 drives the clamping assembly 6 with the cans to the position above the box. When the clamping assembly 6 reaches the stacking position, the clamping driving assembly 5 stops driving the clamping assembly 6 to move horizontally, so that the clamping assembly 6 moves downward again. When the bottom of the cans comes into contact with the bottom inside of the box, the upper clamping plates 62 of the clamping assembly 6 open with the lower clamping plates 63 to put the cans into the box. At the same time, with the opening of the upper clamping plates 62, the locking rods 71 pressed into the upper clamping plates 62 protrude from the upper clamping plates 62 to release the locking of the sliding rods 631. The sliding rods 631 can move in the upper clamping plates 62 again. After the clamping assembly 6 releases the cans, the driving assembly 5 lifts the clamping assembly 6 and moves it to the multi-position positioning assembly 3. At this time, the lower clamping plates 63 have naturally dropped to the lowest end. When the clamping assembly 6 returns to the position above the multi-position positioning assembly 3, the next batch of cans is also positioned by the multi-position positioning assembly 3. This process is repeated until the first box is filled. In the process of the clamping assembly 6 returning to the position above the multi-position positioning assembly 3, the first box is conveyed out of the device, so that the second box reaches the loading position and waits for loading cans.
