Description

Technical Field

[0001] The utility model relates to the technical field of picking mechanical claws, in particular to a broccoli picking mechanical claw which is adaptable to various pedicel lengths. Background Art

[0002] In modern broccoli agricultural production activities, picking broccoli heads is the most time-consuming and laborious part of the entire production process. During the picking process, the picked fruits must be protected from mechanical damage to the greatest extent possible. Therefore, in most cases, farmers mostly use manual picking. At present, there are relatively few mechanical claws for picking fruits of crops such as broccoli that are close to the ground and have thick stalks, and none of them can meet the requirements of picking broccoli with various stalk lengths. Therefore, a broccoli picking mechanical claw that can adapt to various stalk lengths is needed to solve the above problems.

[0003] The prior art has the following deficiencies: The "broccoli picking mechanical claw adapted to various pedicel lengths" in the prior art with application number 201921885228.8 "includes a base, a support arm plate, a push-out assembly, a cutting assembly, a fixed panel, a first hinge and a fixed ring; the push-out assembly includes a guide column, an upper mounting plate, a translation drive member 1, a piston rod 1, a movable plate, a second hinge, a connecting plate and a third hinge; the translation drive member 1 is fixed to the upper mounting plate and drives the movable plate to translate; the three guide columns are evenly distributed along the circumference, and The top ends are all fixed to the upper mounting plate; the movable plate and the three guide columns all form a sliding pair; the bottom ends of the three guide columns are all fixed to the base; the movable plate is arranged between the upper mounting plate and the base; the three support arm plates are evenly distributed along the circumference, one end of each is fixed to the base, and the other end is fixedly connected to the fixing ring through a fixed panel; the three connecting plates are evenly distributed along the circumference, one end of each is hinged to the movable plate through a second hinge; the cutting assembly includes a cutting mounting plate, a cylinder mounting seat, a second translation driving member, a second piston rod, a cutting knife mounting seat and a cutting blade".

[0004] The above-mentioned equipment can adapt to the picking of broccoli with various pedicel lengths by providing a pushing component, a cutting component, etc., but the cutting blade will inevitably become blunt after long-term use. In order to maintain the overall sharpness of the cutting component, the cutting blade needs to be polished or replaced regularly. The cutting blade of the above-mentioned equipment is often difficult to disassemble and assemble after being fixed and installed, which makes it inconvenient to polish and replace the cutting blade. In addition, since the broccoli heads are of different sizes, the fixing ring of the above-mentioned equipment cannot fit the broccoli head very well. The broccoli head will inevitably hit the fixing ring during the movement of the mechanical claw. Since the fixing ring is made of a hard material, it is easy to cause damage to the broccoli head.

[0038] The working principle and use process of the utility model are as follows: the mounting plate 1 is mounted on the three-axis motion platform, and then the three-axis motion platform is driven to move by external force, and the broccoli picking mechanical claw can perform broccoli picking operations. When the mechanical claw is located above the broccoli, the output end of the second cylinder 15 moves downward to drive the three sets of mounting parts 14 to flip inward, thereby causing the three sets of cutters 8 to flip toward the broccoli.

At the same time, the cutter 8 is moved outward to make the connecting block 902 disengage from the connecting groove 901 to complete the disassembly of the cutter 8. At this time, the cutter 8 can be polished by a polishing tool, or the cutter 8 can be replaced. The corresponding pull rod 909 is pulled to make the fixing rod 905 completely located in the empty groove 903 as a whole, and the connecting block 902 is clamped in the connecting groove 901. The pull rod 909 is loosened, and the spring 904 can make the fixing rod 905 rebound and reset. The fixing rod 905 will pass through the connecting block 902 and be located in the fixing groove 906. The connecting block 902 can be limited and fixed, and the installation of the cutter 8 can be completed. The disassembly and assembly of the cutter 8 is relatively convenient, which can facilitate the polishing and replacement of the cutter 8 of the broccoli picking mechanical claw.
