Description

Technical Field

[0001] The utility model relates to the technical field of fruit picking, in particular to a tomato picking auxiliary device. Background Technique

[0002] With the growth of the fruit tree planting industry, China's tomato output has ranked first in the world. When it comes to the tomato harvest season, tomato picking has become an important issue.

[0003] With the progress of technology, many picking machines have emerged. They can identify tomatoes intelligently through cameras and then control the robotic arms to pick tomatoes. Most of the current picking robotic arms pick tomatoes through grippers or suction cups. When the grippers or suction cups pick tomatoes, if the force of the grippers or the suction force of the suction cups is not well controlled, the tomatoes are likely to fall off, resulting in the tomatoes dropping to the ground and reducing the picking efficiency.

[0004] Therefore, a tomato picking auxiliary device is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide a tomato picking auxiliary device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tomato picking auxiliary device includes a picking arm, a gripper is installed at the end of the picking arm, a fixing hoop is installed outside the picking arm, a support plate is installed below the fixing hoop, a support frame is installed on one side of the support plate, and a cloth bag is installed below the support frame;

[0007] A finger cylinder is installed at the bottom end of the support plate, and two connecting rods for separating the cloth bag are symmetrically installed on the finger cylinder.

[0008] Preferably: The cloth bag is composed of two symmetric semi-surrounding fabrics.

[0009] Preferably: The two connecting rods are respectively connected to the bottom end of the cloth bag.

[0010] Preferably: Magnet strips are symmetrically installed on the cloth bag, and the magnet strips are flexible.

[0011] Preferably: The cloth bag is located below the gripper.

[0012] Preferably: A reinforcing plate is installed between the support frame and the support plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When tomatoes fall off, they will fall into the interior of the cloth bag, and then the cloth bag moves along with the picking arm. When it moves into the collection box, the finger cylinder controls the opening of the cloth bag, enabling the tomatoes to fall into the collection box, avoiding the situation where tomatoes fall to the ground and ensuring the picking efficiency.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] Embodiment

[0020] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: A tomato picking auxiliary device includes a picking arm 1, a clamping jaw 2 is installed at the end of the picking arm 1, a fixing hoop 3 is installed on the outside of the picking arm 1, a support plate 4 is installed below the fixing hoop 3, a support frame 5 is installed on one side of the support plate 4, and a cloth bag 6 is installed below the support frame 5;

[0021] A finger cylinder 8 is installed at the bottom end of the support plate 4, and two connecting rods 9 for separating the cloth bag 6 are symmetrically installed on the finger cylinder 8.

[0022] As Figure 2 and Figure 3 shown: The cloth bag 6 is composed of two symmetric semi-enclosing fabrics, and the two connecting rods 9 are respectively connected to the bottom end of the cloth bag 6; Through the above settings, the two connecting rods 9 are respectively connected to the two fabrics that make up the cloth bag 6, so that the lower part of the cloth bag 6 can be opened and closed by the movement of the connecting rods 9, facilitating the temporary storage and placement of tomatoes.

[0023] As Figure 2 and Figure 3As shown: Magnet strips 7 are symmetrically installed on the cloth bag 6, and the magnet strips 7 are flexible; through the above settings, when the cloth bag 6 is closed, the magnet strips 7 can suck and close the gap of the cloth bag 6, avoiding the situation of tomato shedding. The flexible material allows the magnet strips 7 to fold along with the cloth bag 6.

[0024] As Figure 1 shown: The cloth bag 6 is located below the clamping jaw 2; through the above settings, tomatoes can be received more precisely, avoiding the situation of tomato dropping.

[0025] As Figure 2 and Figure 3 shown: A reinforcing plate 10 is installed between the support frame 5 and the support plate 4; through the above settings, the overall strength is improved.

[0026] Working principle: The picking arm 1 drives the clamping jaw 2 to move, and the clamping jaw 2 clamps and picks tomatoes. When the tomatoes fall off, the picking arm 1 drives the tomatoes to move into the collection device to collect the tomatoes.

[0027] At the same time, during picking, when the clamping jaw 2 clamps the tomatoes, if the tomatoes fall off the clamping jaw 2, they will fall into the cloth bag 6. The cloth bag 6 follows the picking arm 1 to move into the collection device, and then the finger cylinder 8 drives the two connecting rods 9 to move. The two connecting rods 9 separate the cloth bag 6 from below, so that the tomatoes fall from the cloth bag 6 into the collection device, avoiding the situation of tomatoes falling to the ground. This ensures the efficiency of tomato picking.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
