Description

Technical Field

[0001] The utility model belongs to the technical field of grab buckets, and particularly relates to a grab bucket anti-leakage device. Background Art

[0002] A grab bucket is a material taking device widely used for loading and unloading bulk goods. With its simple and dexterous shape structure and reliable and stable working mode, it is widely used in various water transportation and freight occasions. When the grab bucket grabs materials and moves, due to the imperfect closure between the two bucket bodies of the grab bucket, it is easy to cause the phenomenon of material leakage, polluting the on-site environment, threatening the safety of on-site personnel, and causing material waste at the same time.

[0003] Therefore, it is necessary to design a grab bucket anti-leakage device that can close the gap below the grab bucket after the material is grabbed to avoid material leakage to solve the current technical problems. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a grab bucket anti-leakage device that can close the gap below the grab bucket after the material is grabbed to avoid material leakage.

[0005] The technical solution of the utility model is as follows: a grab bucket anti-leakage device, including a first bucket body and a second bucket body. Telescopic mechanisms are arranged on both sides of the first bucket body. The upper end of the telescopic mechanism is rotatably connected to the first bucket body. The lower end of the telescopic mechanism is provided with an anti-leakage pressure plate. The anti-leakage pressure plate corresponds to the gap when the first bucket body and the second bucket body are closed. A rotary drive mechanism for driving the telescopic mechanism to rotate is arranged on the side surface of the first bucket body.

[0006] The telescopic mechanism has a mounting seat rotatably connected to the first bucket body. One end of the mounting seat is fixedly provided with an outer cylinder body. An inner rod body is slidably sleeved inside the outer cylinder body. A screw rod threadedly connected to the inner rod body is rotatably arranged inside the mounting seat. A telescopic drive motor for driving the screw rod to rotate is arranged at one end of the mounting seat away from the outer cylinder body. The bottom end of the inner rod body is fixedly connected to one end of the anti-leakage pressure plate.

[0007] The rotary drive mechanism has a support plate fixedly arranged on the side surface of the first bucket body. A driven gear is fixedly arranged on one side of the telescopic mechanism. The driven gear is rotatably connected to the support plate. A rotary drive motor for driving the driven gear to rotate is arranged on the support plate.

[0008] A driving gear is assembled on the rotary drive motor. The driving gear meshes with the driven gear.

[0009] One side of the rotation drive motor is fixedly equipped with a motor mounting plate, and the motor mounting plate is fixedly welded to one side of the support plate.

[0010] A elastic pad is fixedly arranged on the top of the leak-proof pressing plate.

[0011] The elastic pad is a rubber pad.

[0012] Advantages of the present utility model: In the present utility model, before the grab grabs materials, the telescopic mechanism extends, the leak-proof pressing plate moves away from the first hopper body, and the rotation drive mechanism drives the leak-proof pressing plate to rotate to the side away from the second hopper body to avoid affecting the material grabbing. After the material grabbing is completed, after the grab is lifted upward by a certain height, the rotation drive mechanism drives the telescopic mechanism to rotate so that the leak-proof pressing plate is directly below the gap between the first hopper body and the second hopper body. Then the telescopic mechanism shortens, causing the leak-proof pressing plate to move upward to abut against the bottom of the gap, and the bottom of the gap is closed by the leak-proof pressing plate, thereby avoiding the occurrence of material leakage during the hoisting process.

[0019] like Figures 1 to 4 As shown, the grab bucket leakage prevention device comprises a first bucket body 1 and a second bucket body 2. Telescopic mechanisms 3 are arranged on both sides of the first bucket body 1. The upper end of the telescopic mechanism 3 is rotatably connected to the first bucket body 1. The lower end of the telescopic mechanism 3 is arranged with an anti-leakage pressure plate 5. The anti-leakage pressure plate 5 corresponds to the gap when the first bucket body 1 and the second bucket body 2 are closed. A rotating drive mechanism 4 for driving the telescopic mechanism 3 to rotate is arranged on the side of the first bucket body 1. Before the grab bucket grabs the material, the telescopic mechanism 3 is extended, and the anti-leakage pressure plate 5 is away from the first bucket body 1. The rotary drive mechanism 4 drives the anti-leakage pressure plate 5 to rotate to the side away from the second bucket body 2 to avoid affecting the material grabbing. After completing the material grabbing, the grab bucket is lifted up to a certain height, and the rotary drive mechanism 4 drives the telescopic mechanism 3 to rotate, so that the anti-leakage pressure plate 5 is located directly below the gap between the first bucket body 1 and the second bucket body 2, and then the telescopic mechanism 3 is shortened to move the anti-leakage pressure plate 5 up to abut against the bottom of the gap, and the bottom of the gap is closed by the anti-leakage pressure plate 5, thereby avoiding leakage during the lifting process.

[0020] In some embodiments, as a specific implementation of the telescopic mechanism 3, as Figure 2 and 3 As shown, the telescopic mechanism 3 has a mounting seat 31 rotatably connected to the first bucket body 1, one end of the mounting seat 31 is fixedly provided with an outer cylinder 32, the inner sliding sleeve of the outer cylinder 32 is provided with an inner rod body 33, the inner rotation of the mounting seat 31 is provided with a screw 34 threadedly connected to the inner rod body 33, and the end of the mounting seat 31 away from the outer cylinder 32 is provided with a telescopic drive motor 35 for driving the screw 34 to rotate, the bottom end of the inner rod body 33 is fixedly connected to one end of the anti-leakage pressure plate 5, and the telescopic drive motor 35 can drive the screw 34 to rotate forward and reverse. When the screw 34 rotates, the threaded structure between the screw 34 and the inner rod body 33 cooperates to drive the inner rod body 33 to telescopically move inside the outer cylinder 32, thereby realizing the extension or shortening of the telescopic mechanism.

[0021] In some embodiments, Figure 1 and 4As shown, the rotation drive mechanism 4 has a support plate 41 fixedly arranged on the side of the first hopper body 1. One side of the telescopic mechanism 3 is fixedly provided with a driven gear 43, and the driven gear 43 is rotatably connected to the support plate 41. A rotation drive motor 42 for driving the driven gear 43 to rotate is arranged on the support plate 41. The rotation drive motor 42 drives the driven gear 43 to drive the telescopic mechanism 3 to rotate, so as to realize the swing and reset of the telescopic mechanism 3 in the direction away from the second hopper body 2.

[0022] In some embodiments, a driving gear (not shown in the figure) is assembled on the rotation drive motor 42. The driving gear meshes with the driven gear 43. The rotation drive motor 42 drives the driving gear to rotate. The driving gear meshes with the driven gear 43 to drive the driven gear 43 to rotate, and then the driven gear 43 drives the telescopic mechanism 3 to rotate.

[0023] In some embodiments, a motor mounting plate 44 is fixedly assembled on one side of the rotation drive motor 42. The motor mounting plate 44 is welded and fixed on one side of the support plate 41. The rotation drive motor 42 is assembled and fixed on one side of the motor mounting plate 44 through bolts.

[0024] In some embodiments, an elastic pad 6 is fixedly arranged on the top of the leak-proof pressing plate 5; specifically, the elastic pad 6 is a rubber pad. Through the elastic pad 6, it can be closely attached to the bottoms of the first hopper body 1 and the second hopper body 2 on both sides of the gap to avoid material leakage.

[0025] So far, the embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

[0026] The above-described embodiments only represent some implementation manners of the present invention.
