[0002] The loader bucket structure usually consists of a bucket body, wear plates, reinforcement strips, bucket connecting ears and protective equipment, and some loaders are specially designed for excavating silt or wet and soft soil.

[0003] The patent with patent announcement number CN220080130U relates to a loader bucket structure, including a blade plate, a baffle plate and bucket teeth. The baffle plate is fixedly connected to the top of the blade plate, and the bucket teeth are inserted into the front end of the blade plate. A cylindrical long groove is opened in the blade plate, and rectangular openings are opened in the cylindrical long groove at intervals up and down. The patent is through opening a cylindrical long groove inward on the side of the blade plate, and a cylinder is inserted into the cylindrical long groove and fixedly connected to the bottom of the cylindrical long groove with a first spring. At the same time, rectangular openings are sequentially spaced on the cylindrical long groove, and the rectangular openings correspond to bucket teeth. A rectangular groove is provided in the bucket tooth, and an inclined block and a second spring are provided in the rectangular groove. When force is applied to the cylinder, the cylinder will lift the inclined block and retract it into the rectangular groove, and the bucket teeth can be removed. When the bucket teeth need to be installed, the front end of the blade plate will push the inclined block into the rectangular groove, and the bucket teeth can be directly pressed into the blade plate with force, so that the bucket teeth are easy to disassemble when replaced after wear, and the workload is reduced.

[0014] The present invention provides a loader bucket structure having the following beneficial effects: (1) The bucket structure of the loader moves to the right side through the U-shaped frame under the elastic force of the shielding spring. The U-shaped frame moves to the right side to seal the installation frame. The sealing installation frame can effectively prevent debris such as silt and sand from entering the installation area of ​​the bucket rack when the bucket rack is replaced, thereby reducing the jamming or loosening of the bucket rack caused by debris, thereby improving the operation efficiency of the loader in excavating silt. The connection between the installation frame and the bucket rack is protected by the protective frame in cooperation with the elastic force of the protective spring.

[0015] (2) The bucket structure of the loader can clean the residual sludge inside the bucket body and discharge it through the square hole. The residual sludge will increase the weight of the bucket. By cleaning the residual sludge inside the bucket body, the burden of the bucket body can be reduced, thereby improving the overall performance and efficiency of the loader operation. The hollow plate moves away from the servo motor to reset and drive the stirring plate to move. The stirring plate reciprocates to stir the sludge inside the bucket body. The reciprocating motion of the stirring plate can effectively redisperse the particles and water in the sludge, thereby improving the fluidity of the sludge, reducing the obstruction caused by viscosity or agglomeration, and then increasing the working volume of the bucket body.

[0016] (3) The bucket structure of the loader pushes the silt that falls on the right side of the receiving plate by moving the receiving plate toward the annular block. The silt on the right side of the receiving plate is pushed by the receiving plate and falls back into the bucket body under the action of its own gravity. The receiving plate pushes the silt and makes it flow back into the bucket body, which can prevent the silt from overflowing or falling during the operation of the loader, thereby improving the operation efficiency of the loader. The receiving plate moves toward the annular block and hits the annular block to generate vibration. The vibration of the receiving plate further enhances the effect of pushing the silt. The vibration can enhance the fluidity of the silt and make it looser, thereby avoiding the adhesion caused by long-term accumulation of silt. BRIEF DESCRIPTION OF THE DRAWINGS

The sealing installation frame 2 can effectively prevent silt, sand and other debris from entering the installation area of ​​the bucket rack 3 when replacing the bucket rack 3, thereby reducing the jamming or loose installation of the bucket rack 3 caused by debris.

[0021] A No. 1 spring is arranged between the U-shaped rod 5 and the mounting frame 2, one end of the No. 1 spring is arranged on the left side of the mounting frame 2, and the other end is arranged on the right side of the U-shaped rod 5. The No. 1 spring can drive the U-shaped rod 5 to reset, and the U-shaped rod 5 passes through the inner and outer walls of the mounting frame 2. The U-shaped rod 5 is in contact with the mounting groove 4. The protective frame 10 can effectively absorb the impact force of external blocks, thereby preventing the connection between the bucket rack 3 and the mounting frame 2 from being subjected to severe impact and friction, thereby improving the stability of the bucket structure.

[0022] The U-shaped frame 6 penetrates the inner and outer walls of the mounting frame 2 , contacts the bucket rack 3 , contacts the bottom of the bucket body 1 , and the protective frame 10 collides with the block so that the protective frame 10 moves upward under the reaction force of the collision.

[0023] When the present embodiment is working, when the bucket rack 3 needs to be replaced, the U-shaped rod 5 is manually pulled to move away from the U-shaped frame 6, and the U-shaped rod 5 moves away from the U-shaped frame 6 to break away from the contact with the mounting groove 4 and release the limit on the bucket rack 3. After the limit of the bucket rack 3 is released, the bucket rack 3 is pulled out from the inside of the mounting frame 2 with the help of an external device. At the same time, the bucket rack 3 is pulled out from the inside of the mounting frame 2 to break away from the contact with the U-shaped frame 6 and release the limit on the U-shaped frame 6. After the limit of 6 is released, the U-shaped frame 6 moves to the right under the elastic force of the shielding spring 7, and the U-shaped frame 6 moves to the right to seal the installation frame 2. After the bucket rack 3 is pulled out from the inside of the installation frame 2, the new bucket rack 3 is inserted into the inside of the installation frame 2.

The shielding spring 7 is squeezed by the U-shaped frame 6 to deform and accumulate force. When the bucket rack 3 continues to move so that the U-shaped rod 5 is aligned with the installation groove 4, the U-shaped rod 5 moves toward the U-shaped frame 6 under the elastic force of the first spring. The U-shaped rod 5 moves toward the U-shaped frame 6 and contacts the inner wall of the installation groove 4 to restore the limit of the new bucket rack 3. After the new bucket rack 3 is firmly limited by the U-shaped rod 5, the loader operation drives the bucket body 1 to move and excavate the silt. When encountering blocks during sludge excavation, the bucket body 1 will cause the protective frame 10 to contact and collide with the blocks first. The collision between the protective frame 10 and the blocks will cause the protective frame 10 to move upward under the reaction force of the collision. The protective frame 10 moves upward to squeeze the protective spring 11. The protective spring 11 is deformed and accumulates force due to the squeezing of the protective frame 10. The protective frame 10 cooperates with the elastic force of the protective spring 11 to protect the connection between the mounting frame 2 and the bucket rack 3.

The connecting plate 137 is fixedly mounted on the circumferential surface of the rotating rod 133. Through the reciprocating motion of the stirring plate 134, the particles and water in the sludge can be effectively redispersed, thereby improving the fluidity of the sludge, reducing the obstruction caused by viscosity or agglomeration, and thereby increasing the operating volume of the bucket body 1.

[0025] The rotating rod 133 passes through the rear side of the sealing frame 12, and a seal is arranged between the rotating rod 133 and the sealing frame 12.

The vibration can enhance the fluidity of the sludge and make it looser, thereby avoiding the adhesion phenomenon caused by long-term accumulation of sludge.

[0029] When the present embodiment is working, the U-shaped frame 6 moves to the right side to break away from the contact with the shielding plate 131 and releases the limit on the shielding plate 131. After the limit on the shielding plate 131 is released, the shielding plate 131 moves toward the direction close to the protective frame 10 under the elastic force of the No. 3 spring. The shielding plate 131 moves toward the direction close to the protective frame 10 to release the blocking of the square hole 8. After the blocking of the square hole 8 is released, the high-pressure flushing equipment can be used to clean the sludge remaining inside the bucket body 1 and discharge it through the square hole 8. When the loader drives the bucket body 1 to move and excavate the sludge, the servo motor 132 drives the rotating rod 133 to rotate, and the rotating rod 133 rotates to drive the stirring plate 134 to rotate.

The No. 2 spring is squeezed by the hollow plate 136 to deform and accumulate force. When the stirring plate 134 continues to rotate and disengages from the contact with the arc panel 135, the stirring plate 134 is separated from the contact with the arc panel 135, so that the hollow plate 136 moves and resets in the direction away from the servo motor 132 under the elastic force of the No. 2 spring. The hollow plate 136 moves and resets in the direction away from the servo motor 132, driving the stirring plate 134 to move.
