[0034] In summary:

[0035] In the present invention, the plane formed by the axis of the rotating hole 6 and the axis of the lug connecting pin 3 is perpendicular to the inner wall slope of the bucket body 1 away from the lug connecting pin 3, and the axis of the rotating hole 6 coincides with the intersection of the two planes; this design The main function is to make the radius of the arc-shaped rail 4 rotate around the rotating pin 26 small, and increase the strength and stability of the bucket body 1 wall; the rotating pin 26 is opened on the bucket body 1 wall where the shovel teeth 27 are installed, so that When the bucket body 1 is digging the soil, it rotates relative to the rotation pin 26 so that the shovel teeth 27 can be perpendicular to the ground. The wall of the bucket body 1 with the shovel teeth 27 installed on the bucket body 1 will not be affected by the soil layer. Under pressure, the shovel teeth 27 will only receive the force perpendicular to the ground, which can effectively protect the bucket and enable the bucket to withstand greater force when digging; the role of the hydraulic torque converter 23 is to reduce the torque. When the bucket body 1 digs harder things, reduce the speed and increase the torque, so that the bucket body 1 can dig the soil with greater force; the function of the trigger type telescopic plate 15 is to During the movement of the arc-shaped shell 14 in the rail compartment 5 under the drive of the second transmission gear 21, when the second transmission gear 21 rotates to contact the trigger switch 16, the trigger telescopic plate 15 will Extend, to withstand the next arc-shaped shell 14, so that the next arc-shaped shell 14 cannot swing, and enables the second transmission gear 21 to pass through the gap between the two arc-shaped shells 14; the function of the stopper 19 is to block Adjacent to the arc-shaped shell 14, the arc-shaped shell 14 cannot swing, so that the arc-shaped shell 14 can form the arc-shaped rail 4. The function of the arc-shaped rail warehouse 5 is to store the arc-shaped shell 14 that is not driven by the second transmission gear 21 to prevent When the bucket body 1 is digging, the arc shell 14 affects the digging of the bucket body 1; the transmission sleeve 25 is installed on the rotating inner ring of the hydraulic motor 24, and the third transmission gear 22 is installed on the transmission sleeve 25. The transmission gear 22 meshes with the first transmission gear 20, the second transmission gear 21 meshes with the arc rail 4, and the hydraulic motor 24 provides power to move the arc rail 4, driving the bucket body 1 to rotate relative to the rotating pin 26, and the bucket The bucket body 1 excavates soil; the function of the curved rail 4 is to transmit the power of the hydraulic motor 24, so that the bucket body 1 rotates relative to the rotating pin 26 for excavation; the function of the pressure plate 30 and the trigger block 46 is, So that when the bucket teeth 27 are not perpendicular to the ground, the trigger block 46 affects the rotation of the hydraulic motor 24, so that the bucket teeth 27 can be perpendicular to the ground for shoveling operations; the first return spring 32 and the second The function of the second return spring 40 is that when the pressure receiving plate 30 is moved under pressure, the first telescopic rack 41 and the second telescopic rack 34 will not interfere with each other; the function of the safety plate 28 is to identify whether the tooth 27 is perpendicular to Digging the ground; the function of the pressure plate 30 is that when the bucket body is not perpendicular to the ground, the safety plate 28 installed on the shovel teeth 27 will be under pressure, so that the safety plate 28 will be on the shovel The teeth 27 slide on the outer wall. At this time, the movement of the safety plate 28 will be transmitted to the pressure plate 30, so that the first telescopic rack 41 and the second telescopic rack 34 move, the first extension of the movement The retractable rack 41 and the second retractable rack 34 will exert pressure on the force plate. Since the tooth 27 is not perpendicular to the ground at this time, the outer wall of the tooth 27 on one side will contact the ground. The pressure plate 30 will exert a force on the wall of the shovel tooth 27, thereby achieving the effect of strengthening the strength of the shovel tooth 27; the function of the oil circuit cooperation between the first hydraulic cylinder 45 and the second hydraulic cylinder 47 is to move the moving rod 36 It is transmitted to the sliding block 61, and the corresponding oil outlet 57 and the oil outlet pipe are matched by the sliding of the sliding block 61 to control the forward and reverse rotation of the hydraulic motor 24.

[0036] The specific implementation is that when the equipment of the present invention is used for shoveling operations, such as Picture 10 As shown in b, the shovel teeth 27 are perpendicular to the soil surface and enter the soil. The hydraulic system of the excavator drives the hydraulic motor 24 to work, the hydraulic motor 24 drives the transmission sleeve 25 to rotate, and the transmission sleeve 25 drives the third transmission gear 22 to rotate, and the third transmission gear 22 Drive the first transmission gear 20 to rotate, the first transmission gear 20 drives the second transmission gear 21 to rotate, and the second transmission gear 21 drives the arc rail 4 to move, so that the arc rail 4 drives the bucket body 1 through the lug connecting pin 3 Rotate relative to the rotating pin 26, such as Picture 10 As shown in c, the bucket body 1 at this time begins to excavate soil, until the bucket body 1 turns parallel to the ground, the hydraulic motor 24 stops rotating, and the bucket body 1 ends when the second transmission gear 21 When driving the arc-shaped rail 4 to move, the second transmission gear 21 first drives the arc-shaped housing 14 to move. As the second transmission gear 21 rotates, the second transmission gear contacts the trigger switch 16 on the arc-shaped housing 14, so that the trigger type The telescopic plate 15 extends and bears the next arc-shaped shell 14; the second transmission gear 21 enters the next arc-shaped shell 14 through the trigger-type telescopic plate 15; the second gear 33 continues to rotate so that the arc-shaped shell 14 moves from the arc-shaped rail The arcuate rail 4 is formed out of the bin 5, so that the second transmission gear 21 meshes with the arcuate rail 4 to drive the arcuate rail 4 to move; when the shovel teeth 27 are not vertical to the ground to shovel soil, and the bucket body 1 is away from the excavator When the operator is tilted; the safety plate 28 will move along the strip groove 29 under the force of the soil, the moving safety plate 28 will drive the connecting block 44 mounted on it to move, and the connecting block 44 will push the third rack 39 movement; the third rack 39 will drive the second one-way gear 63 to move, the second one-way gear 63 will drive the first gear 31 to move, the first gear 31 will drive the fixed shaft 38 to move, and the fixed shaft 38 will move Will drive the second gear 33 and the third gear 37 to move, and the second gear 33 will drive the second telescopic rack 34 to move. The moving second telescopic rack 34 will exert a pressure on the pressure plate 30, thereby making the The pressure plate 30 will reinforce the shovel teeth 27 so that the shovel teeth 27 can withstand greater force from the soil; the moving second telescopic rack 34 will drive the moving rod 36 to move; compress the first return spring 32 to drive the moving rod 36 moves laterally to compress the first hydraulic cylinder 45. The first hydraulic cylinder 45 drives the second hydraulic cylinder 47 to expand and contract through a hose, pushing the sliding block 61 to move, so that the first oil outlet 48 and the first oil outlet pipe 49 are connected. The third oil outlet 52 and the third oil outlet pipe 53 are connected. The hydraulic oil in the hydraulic oil storage chamber 43 enters the hydraulic motor 24 through the first oil outlet pipe 49 through the hose, and drives the hydraulic motor 24 to rotate, making the bucket body 1 Rotate so that the shovel teeth 27 can shovel the soil perpendicular to the ground; when the shovel teeth 27 are not perpendicular to the ground and the bucket body 1 is tilted toward the operator of the excavator; the safety plate 28 will move along with the force of the soil. When the strip groove 29 moves, the moving safety plate 28 will drive the connecting block 44 mounted on it to move, so that the connecting block 44 will in turn drive the fourth rack 35, the first one-way gear 62, and the third Gear 37, second gear 33, first gear 31, first telescopic rack 41, second telescopic rack 34; the moving first telescopic rack 41 and second telescopic rack 34 will drive the moving rod 36 to move; The moving rod 36 will stretch the first hydraulic cylinder 45. The first hydraulic cylinder 45 drives the second hydraulic cylinder 47 to expand and contract through a hose, pushing the sliding block 61 to move, so that the second oil outlet 51 and the second outlet The oil pipe 50 is connected, the fourth oil outlet 55 and the fourth oil pipe 54 are connected, the hydraulic oil storage cavity The hydraulic oil in 43 passes through the hose and enters the hydraulic motor 24 through the second oil outlet pipe 50, and drives the hydraulic motor 24 to reverse, so that the bucket body 1 rotates, so that the shovel teeth 27 can shovel the soil perpendicular to the ground; When it is perpendicular to the ground, the safety plate 28 will not move, and the bucket will continue to shovel; when the bucket body 1 is filled with soil and starts to pour the soil, the hydraulic motor 24 reverses so that the curved rail 4 follows the shovel When the soil moves in the opposite direction, the bucket body 1 rotates relative to the rotating pin 26 so that the soil is poured out of the bucket body 1.
