Description

Rotatable multi-clack grab bucket Technical Field The utility model relates to the technical field of grab buckets, in particular to a rotatable multi-petal grab bucket. Background A rotatable multi-lobed grapple is a device specifically designed to grasp and handle large amounts of material. The rotatable multi-flap grab bucket has a unique design structure and strong functions, is widely applied to carrying and loading of various materials, such as coal, ore, grain, chemical fertilizer and the like due to high-efficiency loading capacity and flexible operability, and is particularly suitable for loading and unloading operation of large materials. Chinese patent (bulletin number: CN 221275019U) discloses a rotatable multi-flap grab including a base plate, a support column, a circumferential rotation mechanism, a lifting rotation mechanism and a grab bucket mechanism, the base plate is movably connected with the support column, the circumferential rotation mechanism is mounted on the support column, the lifting rotation mechanism is connected with the circumferential rotation mechanism, the grab bucket mechanism is mounted under the circumferential rotation mechanism, the circumferential rotation mechanism includes a first motor, a first rotating shaft, a main gear, an internal gear and a top frame, the lifting rotation mechanism includes a first telescopic cylinder, a second motor, a second rotating shaft and a connecting plate, the grab bucket mechanism includes a mounting block, a second telescopic cylinder and a grab bucket leaf, the circumferential rotation mechanism allows the grab bucket to rotate in a horizontal plane, thereby changing the working direction of the grab bucket, which means that the grab bucket can work in a circumferential range, the grab bucket mechanism is multi-flap, it can adjust the open and close states of the grab bucket leaf as required, so that various objects can be handled, but the grab bucket of the device is fixed in position with the top frame, so that the working range of the grab bucket is limited. To solve the above problems, we propose a rotatable multi-flap grab. Disclosure of utility model In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a rotatable multi-petal grab bucket, which comprises a support column, wherein the top end of the support column is rotationally connected with a top frame, the top end of the top frame is fixedly connected with a plurality of sleeves, the inside of each sleeve is slidably connected with an extension rod, the end part of each extension rod is fixedly connected with a mounting plate, the bottom end of each mounting plate is fixedly connected with a grab bucket main body, the outer end of each sleeve is fixedly connected with a second motor, the output end of each second motor is fixedly connected with a threaded rod, the threaded rods are rotationally connected inside the corresponding sleeve, the outer side threads of each threaded rod are connected with movable blocks, and the movable blocks are fixedly connected to one end of each extension rod, which faces the support column.
