Description

Technical Field

[0001] This utility model relates to the field of grass-grabbing claw technology, specifically an electrically driven grass-grabbing claw. Background Technology

[0002] Currently, the powered grippers on weed-cutting boats are mainly hydraulically driven. Hydraulically driven grippers have advantages such as sufficient power and large gripping force, but they require supporting pump stations, cylinders, pipelines, etc., resulting in complex structures, large weight, high manufacturing costs, and high operating and maintenance costs. However, weeding on a weed-cutting boat does not require particularly large gripping force; on the contrary, the complex structure and weight would burden the boat. Therefore, a simplified electrically driven weed-cutting gripper with a simple structure is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an electrically driven grass-grabbing claw, which solves the problem that the hydraulically driven claws on existing weed-cutting boats are complex in structure and heavy in weight, causing inconvenience in use.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An electrically driven grass-grabbing claw includes a left grab bucket and a right grab bucket, and two sets of symmetrical scissor forks are provided between the left grab bucket and the right grab bucket, with the lower ends of the scissor forks fixedly connected to the left grab bucket and the right grab bucket respectively.

[0006] The upper end of the scissor lift is movably hinged with two sets of two left connecting rods and two right connecting rods that are symmetrically connected front and back. The upper ends of the left and right connecting rods are movably hinged to the suspension connecting plate. The bottom of the suspension connecting plate is vertically movably hinged with an electric push rod, and the lower end of the electric push rod is movably hinged to the scissor lift.

[0007] Preferably, the gripping teeth of the left and right grippers are staggered.

[0008] Preferably, the suspension connecting plate has a vertically arranged triangular structure and a suspension connecting hole is provided near the center of the top.

[0009] Preferably, two sets of scissor lifts symmetrically arranged front and rear are rotatably connected to support plates on their pin shafts, and the electric push rod is movably hinged to the scissor lifts through the support plates.

[0010] Preferably, both the left grab bucket and the right grab bucket are frame structures.

[0011] Preferably, both the left grab bucket and the right grab bucket are welded steel pipe structures.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses an electric push rod and a scissor fork to drive the left and right grab buckets to grab and open. It is designed for grabbing grass, and the weight of each grab is relatively light. A 12V battery can drive the lightweight electric-driven grass grabbing claw to complete the grass grabbing work. The electric-driven grass grabbing claw has a simple structure, which is convenient for production, manufacturing, use and maintenance. It can effectively save manufacturing and usage costs and solve the problem that the existing hydraulic-driven claws on weeding boats have a complex structure and heavy weight, which causes inconvenience in use.

[0017] 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.

[0018] like Figure 1-2 As shown, this utility model provides a technical solution: an electrically driven grass-grabbing claw, including a left grab bucket 1 and a right grab bucket 2, the grab teeth of the left grab bucket 1 and the right grab bucket 2 are staggered, the left grab bucket 1 and the right grab bucket 2 are both frame structures, the left grab bucket 1 and the right grab bucket 2 are both welded steel pipe structures, and two sets of symmetrical scissor forks 3 are provided between the left grab bucket 1 and the right grab bucket 2, the lower ends of the scissor forks 3 are fixedly connected to the left grab bucket 1 and the right grab bucket 2 respectively;

[0019] The upper end of the scissor lift 3 is movably hinged with two sets of symmetrical left connecting rods 4 and two sets of symmetrical right connecting rods 5. The upper ends of the left connecting rods 4 and the right connecting rods 5 are movably hinged to the suspension connecting plate 6. The suspension connecting plate 6 is a vertically arranged triangular structure with a suspension connecting hole 601 near the center of the top. The bottom of the suspension connecting plate 6 is vertically hinged to an electric push rod 7. The lower end of the electric push rod 7 is movably hinged to the scissor lift 3. The two sets of symmetrically arranged scissor lift 3 are rotatably connected to the pins of the pins of the two sets of scissor lift 3. The electric push rod 7 is movably hinged to the scissor lift 3 through the support plate 8.

[0020] Working principle:

[0021] The electric push rod 7 pushes the support plate 8 downward, which causes the left connecting rod 4 and the right connecting rod 5 to move closer together, reducing the bottom angle of the scissor 3 and causing the left grab bucket 1 and the right grab bucket 2 to move closer together to grab the aquatic plants. The electric push rod 7 pulls the support plate 8 upward, which causes the left connecting rod 4 and the right connecting rod 5 to move away from each other, increasing the bottom angle of the scissor 3 and causing the left grab bucket 1 and the right grab bucket 2 to move away from each other and open up, releasing the grabbed aquatic plants. The structure is simple and easy to use.

[0022] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
