DETAILED DESCRIPTION

[0027] The utility model will now be further described in detail with reference to the accompanying drawings.

[0028] See also Figures 1 to 4 The utility model provides a technical solution: an experimental device for stone dumping, comprising a driving seat 1 and a stone placing frame 13, the driving seat 1 is fixed on one side of the upper end of the experimental hull, a cavity 3 for the driving block 2 to move is opened in the middle of the upper end of the driving seat 1, a buffer seat 4 is fixedly installed on the upper end of the driving block 2, a driving motor 6 fixed to a screw rod 5 inside the cavity 3 is fixed at the front end of the driving seat 1, and the driving motor 6 is connected to a controller 7 circuit on one side of the front end of the driving seat 1 through a wire;

[0029] Slide blocks 9 matching the outer dimensions of the slide rails 8 are fixed on both sides of the bottom of the driving seat 1. The slide rails 8 are fixedly mounted on the upper end of the driving seat 1. Grooves for placing the balls 10 are provided between the slide blocks 9 and the slide rails 8.

[0030] The upper end of the buffer seat 4 is provided with a slot 12 for installing the load-bearing block 11, a stone placing frame 13 is hinged on one side of the upper end of the load-bearing block 11, and a side cover plate 14 for blocking the stone is hinged on one side of the stone placing frame 13, and the upper end and the other side of the stone placing frame 13 are both open designs;

[0031] A protective plate 29 is provided on one side of the driving seat 1 for separating the block stone placement area. Considering that most of the existing block stone dumping devices are fixed on the hull, during use, the dumping position can often only be changed by adjusting the ship moving distance. It is difficult to temporarily adjust the block stone dumping position according to the dumping position required by the experiment, and it is difficult to achieve a good dumping effect. Therefore, the utility model will drive the block 2 stone placement frame to move to the specified block stone dumping experimental position through the driving seat 1. Compared with the existing method of only being able to change the stone dumping position by moving the hull, it is more convenient. When in use, it is only necessary to turn on the controller 7 according to the required use position during the block stone dumping measurement. The controller 7 will control the number of rotations of the output shaft of the driving motor 6 through the motor driving module inside the driving motor 6. After the output shaft is transmitted to the screw rod 5, the screw rod 5 rotates the specified number of times, and the threaded sleeve 15 is in the guide block 16 and the guide rail 17, the rotational motion is converted into linear motion, that is, the driving seat 1 drives the block 2 stone placement frame to move along the direction of the guide rail 17. After moving to the experimental position, the switch of the hydraulic cylinder 20 is started, and the hydraulic cylinder 20 will drive the moving block 21 to move upward. During the upward movement, the moving block 21 will move along the displacement of the moving rail 22. At this time, the stone placement frame 13 will rotate with the hinge point of the weighing block as the rotation point, and then the switch of the electric push rod 26 is started. The telescopic end of the electric push rod 26 will drive the push block 27 to move along the strip. At this time, the side cover 14 used to block the stone will be opened, and then the stone will be thrown into the river below. According to the experimental needs, a control experiment design with different stone throwing positions is carried out. It is only necessary to drive the block 2 stone placement block to move to different positions on the driving seat 1. It is more convenient than moving the hull to change the stone throwing position.

[0032] Among them, the other end of the screw rod 5 is rotatably connected to the inside of the cavity 3 through a bearing, and a threaded sleeve 15 is installed on the outside of the screw rod 5, and the upper end of the threaded sleeve 15 is fixedly connected to the bottom of the driving block 2. The screw rod 5 cooperates with the threaded sleeve 15 to drive the driving block 2, so that when the screw rod 5 rotates, the threaded sleeve 15 will drive the driving block 2 under the guidance of the guide block 16 and the guide rail 17.

[0033] Among them, guide rails 17 for the longitudinal movement of the guide blocks 16 are fixed on both sides of the trough body 12, and the two guide blocks 16 are symmetrically fixed on both sides of the load-bearing block 11, and a plurality of buffer springs 18 are installed between the bottom of the load-bearing block 11 and the trough body 12, and a plurality of damping rods 19 are installed at the bottom of the trough body 12, and the telescopic ends of the damping rods 19 are fixed to the bottom of the load-bearing block 11. Considering that when the blocks are filled into the block placement frame 13, due to the large volume of the blocks, a crane is generally used to lift the blocks on the experimental hull and move them to the blocks. In the placement frame 13, when the stone block falls from the mechanical claw of the crane to the placement area, there is an impact on the stone block placement frame 13, which will generate an impact force, and the impact force will affect the device. In order to solve this drawback, the utility model will use the buffer spring 18 and the damping rod 19 between the buffer seat 4 and the weighing seat for buffering, that is, the buffer spring 18 absorbs the impact force and releases the elastic potential energy, and when the buffer spring 18 releases the elastic potential energy, the damping rod 19 will suppress the elastic potential energy released until the buffering is completed.

[0034] Among them, a reserved hole for installing the hydraulic cylinder 20 is opened in the middle of the load-bearing block 11, and a moving block 21 is fixedly installed at the telescopic end of the hydraulic cylinder 20, and the moving block 21 is slidably connected to the moving rail 22 at the bottom of the stone placement frame 13. A dust-proof accordion cover 23 is fixed between the load-bearing block 11 and the buffer seat 4. The dust-proof accordion cover 23 is provided to prevent dust or gravel from entering the interior of the buffer seat 4 and affecting the normal use of the buffer spring 18 and the damping rod 19.

[0035] Among them, a resistance block 24 is fixed between the other side of the bottom of the stone placing frame 13 and the load-bearing block 11, and a polyurethane buffer block 25 is fixed on the opposite surfaces of the two resistance blocks 24. The polyurethane buffer block 25 is provided to play a contact buffering role for the non-hinged end of the stone placing frame 13 hinged on the load-bearing block 11, that is, it avoids the bottom of the stone placing frame 13 and the contact surface of the load-bearing block 11 to contact for a long time to produce a wound surface, and when the bottom of the stone placing frame 13 contacts the upper end of the load-bearing block 11, it will cause the inside of the stone placing frame 13 to tilt, which will cause the stone sample placed inside the stone placing frame 13 to fall off. The existence of the resistance block 24 effectively avoids the above two situations.

[0036] Among them, electric push rods 26 are fixed on the front and rear sides of the stone placement frame 13, and push blocks 27 are fixed on the telescopic ends of the two electric push rods 26, and the two push blocks 27 are respectively slidably connected to the bar rails 28 on the front and rear sides of the side cover 14. By setting the electric push rods 26, a control effect is played on the side cover 14. When it is necessary to throw and fill stones, the electric push rods 26 are turned on to drive the side cover 14 to open.

[0037] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
