Specifically, the grab mechanism 600 includes a grab body 601 and a receiving bin 602, the receiving bin 602 is located at the top of the grab body 601, and when the grab body 601 is closed, the receiving bin 602 communicates with the internal space of the grab body 601. The grab bucket body 601 comprises a top frame 6011 and a movable frame 6012 positioned below the top frame 6011, a plurality of hinge seats 6013 are uniformly arranged on the peripheral wall of the top frame 6011 at intervals, hollow pipes 6014 are hinged to the hinge seats 6013, grab bucket pieces 6015 are hinged to the bottom ends of the hollow pipes 6014, one ends of the grab bucket pieces 6015 are hinged to the side walls of the movable frame 6012, a telescopic oil cylinder 6016 is connected between the top frame 6011 and the movable frame 6012, when the top frame 6011 and the movable frame 6012 are close to each other, the grab bucket pieces 6015 are mutually closed, and when the top frame 6011 and the movable frame 6012 are far away from each other, the grab bucket pieces 6015 are mutually unfolded. In the present embodiment, the top frame 6011 has a regular pentagon shape, the hinge seats 6013 have five shapes, and the hollow tube 6014 has a steel tube structure with two ends penetrating.

The material receiving bin 602 is funnel-shaped, the material receiving bin 602 is fixedly connected with the top surface of the top frame 6011, the bottom of the material receiving bin 602 is provided with discharge pipes 603 corresponding to the hollow pipes 6014 one by one, and the bottom end of the discharge pipe 603 is connected with the hollow pipes 6014 through a hose 604.

The grab bucket sheet 6015 comprises an arc steel sheet 60151 and a reinforcing rib 60152 welded and fixed on the back surface of the arc steel sheet 60151, a material leakage hole 60153 is formed in the reinforcing rib 60152 in a penetrating mode, the bottom end of the hollow pipe 6014 stretches into the material leakage hole 60153 and is in rotary connection with the reinforcing rib 60152 through a rotary shaft 6017, when the grab bucket body 601 is closed, a plurality of arc steel sheets 60151 jointly enclose a conical structure with an upper end opening, and the material leakage hole 60153 is located above the opening of the conical structure. The arc steel plates 60151 are made of steel plates with the thickness of 16mm, the bottom ends of the arc steel plates are sharp, when the grab mechanism 600 is closed, the side edges of the arc steel plates 60151 are mutually abutted, and the bottom ends of the arc steel plates are closed. As material enters the interior of the receiving hopper 602, the material may pass through the discharge tube 603, the hose 604, the hollow tube 6014, and the discharge port 60153 in sequence into the conical structure, thereby loading the material into the conical structure.

In addition, the traction mechanism 500 comprises two electric hoists (not shown in the figure), lifting lugs 605 are arranged on two opposite sides of the top surface of the top frame 6011, output ends of the two electric hoists are respectively connected with the two lifting lugs 605 through steel wires 501, and a protective cover 502 is further arranged on the top surface of the feeding frame 400 and positioned on the outer sides of the two electric hoists. The two electric hoists are always synchronously started and stopped to control the two steel wire ropes 501 to synchronously extend or retract, so that the grab mechanism 600 can keep relative balance. In addition, the maximum traction weight of the electric hoist is 25 tons, the sum of the maximum traction weights of the two electric hoists is 50 tons, and the sum of the grab bucket mechanism 600 and the material weight is ensured to be always within the maximum traction amount range of the electric hoist.

It should be noted that, the top surface of the conveying arm 200 and above the belt conveyor 201 is further provided with a hopper 204, and the interior of the hopper 204 is in a cone shape with a wide top and a narrow bottom. When the material falls into the hopper 204 from top to bottom, the material can finally successfully fall onto the belt conveyor 201, and the effect is to prevent the material from being scattered to the outside. The upper surface of the belt conveyor 201 has a high-end and low-end posture, as shown in fig. 6, and the outer surface of the belt conveyor 201 has a uniform anti-slip strip.

In addition, the bottom of the discharge pipe 301 is inclined toward the end side of the conveying arm 200, and when the receiving bin 602 moves to a position right below the bottom end of the discharge pipe 301, the bottom of the discharge pipe 301 is located between the two wire ropes 501. The end-to-end spacing of the belt conveyor 201 and the conveyor arm 200 is greater than the width of the grapple mechanism 600, and the sum of the heights of the grapple mechanism 600 and the hopper 204 is less than the difference in height of the top wall of the cradle 400 and the conveyor arm 200. That is, the grapple mechanism 600 can smoothly pass through the gap between the belt conveyor 201 and the conveying arm 200, and the grapple mechanism 600 can also enter the upper side of the hopper 204.

In summary, in the practical application process of the present embodiment, when the ship unloading operation is required, the belt conveyor 201 is reversed, that is, the material falling on the upper surface of the belt conveyor 201 can move to the side close to the tower 103. The traction mechanism 500 is used for controlling the height of the grab mechanism 600, and the grab mechanism 600 can achieve grabbing action through the telescopic oil cylinder 6016 so as to grab materials in the ship cabin. The traction mechanism 500 then controls the grab mechanism 600 to ascend and pass through the gap at the front end of the belt conveyor 201, then the driving motor 403 acts to control the feeding frame 400 to translate, so that the grab mechanism 600 moves above the hopper 204, and finally the grab mechanism 600 loosens the material and the material falls on the belt conveyor 201 through the hopper 204.

When the present embodiment performs a shipping operation, the belt conveyor 201 is rotated in a forward direction, and the material falls into the receiving hopper 300 through the belt conveyor 201. In the initial state, the receiving bin 602 at the top of the grab mechanism 600 is located directly below the discharge pipe 301, and the grab mechanism 600 is in the closed state. At this time, when the switch valve is opened, the material can enter the receiving bin 602 through the discharging pipe 301, and then enter the grab bucket through the discharging pipe 603 and the hollow pipe 6014. When the interior of the grab is filled with material, the switch valve is temporarily closed, and then the traction mechanism 500 releases the grab mechanism 600 downward, so that the grab mechanism 600 falls to a proper position, and the grab mechanism 600 releases the material again. After completion, the grapple mechanism 600 returns to the initial position again, and the on-off valve opens again, thus reciprocating.

It should be noted that, in order to avoid the blockage of the discharge pipe 603 and the hollow pipe 6014, the loading operation of the present embodiment is only suitable for sand, because the particle diameter of the sand is small, and the blockage phenomenon is not easy to occur. When the loading operation is performed, the time for filling the grab bucket with sand is generally 15-20 seconds, so that the time for opening the switch valve each time is also controlled to be 15-20 seconds, and the excessive sand is prevented from leaking from the top of the receiving bin 602. In addition, when the receiving hopper 300 is about to be filled, the worker needs to shut down or slow down the operation of the belt conveyor 201 to prevent the material from overflowing from the top of the receiving hopper 300. And the top inner wall of the receiving hopper 300 may be provided with a camera mechanism to assist a worker in judging whether the receiving hopper 300 is full.

In addition, the front-back travel of the grab mechanism 600 is small, so the structure of the holder 104 is designed, and the conveying arm 200 is arranged in the holder 104 in a sliding way, and therefore, when the front-back distance of the grab mechanism 600 needs to be adjusted in a large range, the driving equipment on the holder 104 can control the conveying arm 200 to slide back and forth.
