Problems solved by technology

[0002] The silt in the river needs to be cleaned regularly. If the silt in the river is too thick, it will cause a large number of bacteria to multiply, and it will greatly damage the purity of the water source and the navigation and flood discharge capabilities of the river itself. The common dredging method is to use a backhoe hydraulic excavator to dig , when carrying out river dredging work, the transfer and unloading actions are generally realized by manipulating the working device of the excavator, and finally the sludge is poured into the truck next to it. During the silt working process, when the bucket is fully loaded, it is necessary to keep the opening surface of the bucket parallel to the ground, and the bucket will remain in this state until the unloading work is performed, which reduces flexibility and efficiency invisibly; or directly digs Silt, the directly excavated sludge contains a lot of water, which will also make the subsequent sludge treatment procedures more complicated and cumbersome, and the transportation cost will be greatly increased

Embodiment 1

[0025] see Figure 1 to Figure 6 , a river dredging grab device provided in an embodiment of the present invention includes an adjustment mechanism for adjusting the grabbing direction of the grab, a support rod 4, a bucket flap mechanism and a pressure plate mechanism; the adjustment mechanism includes a grab hydraulic cylinder 2, The rocker 9, the connecting rod 11, the connecting seat 12, and the arm 1 of the hydraulic excavator as the frame, and the components of the adjustment mechanism form a plane six-bar mechanism through hinged connection. The driving part of the plane six-bar mechanism is the grab hydraulic cylinder 2 , the plane six-bar mechanism converts the telescopic movement of the grab hydraulic cylinder 2 into the rotary motion of the connecting seat, and increases the rotary angle range of the connecting seat to a large extent; the upper end of the support rod 4 is fixed on the connecting seat 12 of the adjustment mechanism On the top, the support rod 4 moves...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the top of the connecting seat 12 is fixed with an ear plate 15, one side of the ear plate 15 is hinged with the end of the stick 1 through a pin 14, and the other side of the ear plate 17 is hinged through a pin. The shaft 14 is hinged to the end of the connecting rod 11 ; in this embodiment, an ear plate 15 is fixed on the top of the connecting seat 12 to increase the range of rotation angles of the connecting rod 11 around the connecting seat 12 .

Embodiment 3

[0033] The difference between this embodiment and Embodiment 1 is that the outer surface of the bucket petals 6 is welded with arc-shaped reinforcing ribs. When the pressure plate hydraulic cylinder 8 pushes the pressure plate 7 to squeeze the mud, the bucket petals 6 will be subjected to pressure from the inside to the outside. Due to the expansion force, the bucket petals 6 are easily deformed or even damaged, so it is necessary to strengthen the strength and rigidity of the bucket petals 6. Generally, a stiffened plate is a better choice. Since the outer surface of the bucket petals 6 is curved, so the The added ribs are preferably arc-shaped, fitting the surface of the bucket petals 6, and the specific connection method is welding.

Abstract

The invention provides a river channel dredging grab bucket device. The device comprises an adjusting mechanism, a supporting rod, bucket piece mechanisms and a pressing disc mechanism. The adjustingmechanism is a planar six-rod mechanism composed of a bucket rod, a grab bucket hydraulic cylinder, a rocker, a connecting rod and a connecting seat through hinging, wherein the grab bucket hydrauliccylinder is a driving part; the upper end of the supporting rod is fixed to the connecting seat of the adjusting mechanism; and the side wall of the supporting rod is provided with the bucket piece mechanisms uniformly distributed in the circumferential direction. Each bucket piece mechanism comprises a bucket piece hydraulic cylinder and a bucket piece. The lower end of the supporting rod is provided with the pressing disc mechanism, and the pressing disc mechanism comprises a pressure disc hydraulic cylinder fixedly connected with the lower end of the supporting rod, and a pressing disc fixedly connected with a piston rod of the pressure disc hydraulic cylinder. The side wall of each bucket piece is provided with a drainage groove. The river channel dredging grab bucket device takes theplace of a hydraulic excavator bucket mechanism to achieve grabbing, squeezing and removing of river channel sludge, and has the advantages of high convenience flexibility, high efficiency and low cost.
