M362865 五、新型說明： 【新型所屬之技術領域】 本創作係關於一種挖土機抓斗，尤指一種可對抓取物 加壓且透過振動加速脫水’以提高抓取物密度的挖土機抓 斗。M362865 V. New description: [New technical field] This is a kind of excavator grabber, especially an excavator that can pressurize the grab and accelerate the dehydration through vibration to increase the density of the grab. Grab.
【先前技術】 一種已知的挖土機抓斗係如我國專利公報公告第 114798號「碎（散）料抓斗之改良」新型專利案，其主要係[Prior Art] A known excavator grab is a new type of patent case for the improvement of the shredder (gravity grab) in the Chinese Patent Gazette No. 114798.
將抓斗設計成具有如拋物線之曲度，使抓斗得以更輕易地 抓取地上物，且不致於破壞地面。此種抓斗係由複數抓爪 組成，由於抓爪形成有曲度，因此各抓爪朝相對内侧收合 時可構成一取物空間。此種抓斗的優點在於取物空間大， 故可-次取得較大份量的抓取物，但由於各抓爪一經收合 後，其内部的取物空間幾乎是密閉的，換言之，對於抓取 物的内容是無可選擇的，當挖土機開挖的場所水分含量較 :’或作業對象為體積大密度低的膨鬆物時，抓取物中即 的水分或空氣，而嚴重影響開挖作業的效率。故 討，並課求可行的解決方案。問通’有待進一步檢 【新型内容】 因此本創作主要目的在提供一 的挖土機抓斗 其利用特殊的加屢設 種可提高抓取物密度 &與振動機構以壓縮 M362865 ’有效解決既有挖土機抓 不佳的問題。 斗The grapple is designed to have a curvature such as a parabola that allows the grapple to more easily grasp the ground without damaging the ground. The gripper is composed of a plurality of grippers. Since the grippers are formed with curvature, each gripper can form an object space when folded toward the opposite inner side. The advantage of such a grab is that the take-up space is large, so that a larger amount of the grab can be obtained, but since the grippers are folded, the internal take-up space is almost closed, in other words, for grasping The content of the object is not selectable. When the water content of the excavator is more than: 'or the bulk of the object is low bulk density, the water or air in the grab is seriously affected. The efficiency of excavation work. So discuss and seek a workable solution. QT's need to be further inspected [new content] Therefore, the main purpose of this creation is to provide an excavator grab that utilizes special additions and sets to increase the grab density & and the vibrating mechanism to compress M362865 'effectively The problem of poorly grasped excavators.

[Embodiment] M362865 With regard to a preferred embodiment of the present invention, first, as shown in the first and second figures, it has a base (10), a plurality of first pressure cylinders (20), and a plurality of grippers (3〇). And a press machine (40); wherein: in the embodiment, the base (10) has an I-shape, and has an upper seat plate (11), a lower seat plate (12) and a hollow sleeve ( 13) The upper end of the sleeve (13) is coupled with the upper seat plate (11), the lower end of the sleeve (13) extends through the lower seat plate (12), and has an opening; a surface of the upper seat plate (11) is provided with a connecting member ( 14) The connecting member (14) is a U-shaped seat body, and the mounting hole is formed thereon for connecting with the mechanical arm of the excavator or other excavating equipment, and the bottom plate of the upper seat plate (^) is fixed. There are a plurality of hinges (15) for pivotally connecting with the bodies of the first pressure cylinders (2〇), each of the first pressure cylinders (20) has a piston rod (21), and the ends of the piston rods (21) are respectively Each of the grippers (30) is pivotally connected to control the retracting action of each gripper (3〇). The cross section of each gripper (30) has a curvature, the sides of the gripper are tapered from the upper end, and the ends are tapered, and a plurality of meshes are formed on each gripper (3〇). (33) for filtering water; further, each of the grippers (3〇) is provided with a first hub (3彳) and a second hub (32) on the outer side of the other end of the tapered end. The second hub (32) is adjacent to the other end of the gripper (3) and is pivoted on the lower seat plate (12) of the base (10), and the first hinge (31) is located at the second The inner side of the hub (32) has a spacing, and the first hinge (31) is for pivoting with the end portion of the piston rod (21) of the first pressure cylinder (20), thereby, when each first pressure When the piston rod (21) of the cylinder (20) expands and contracts, each of the grippers (3〇) will be retracted with its second hinge (32) as a fulcrum, and when the grippers (3〇) are folded, A space is formed inside. The press machine (40) includes a second pressure cylinder (41), a pressure plate (42) and a vibrator (43), the second pressure cylinder (41) is a piston rod (410) and a pressure plate (42). M362865 is connected to control the pressure plate (42) to rise and lower. The vibrator (43) can be placed on the pressure plate (42) to generate vibration when the pressure plate (42) is pressurized to enhance the pressure effect.
