[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model provides a technical solution: a highly efficient and sealed hydraulic slag squeezing door for a slag scooping machine, comprising a slag squeezing door body 1, a left-seat squeezing door plate 4, a right-seat squeezing door plate 5 and a hydraulic cylinder 7.

The left-seat squeezing door plate 4 and the right-seat squeezing door plate 5 are arranged on both sides of the upper side of the slag squeezing door body 1 close to the material holding chamber 3, and the inner walls of the left-seat squeezing door plate 4 and the right-seat squeezing door plate 5 are both provided with extrusion heads 6. Hydraulic cylinders 7 are penetrated on both sides of the slag squeezing door body 1, and the output ends of the symmetrically arranged hydraulic cylinders 7 are respectively connected to the left-seat squeezing door plate 4 and the right squeezing door plate 5.

[0023] A left sealing seat 8 is arranged above the left seat extruded door panel 4, and a docking groove 9 is provided at the edge of the left sealing seat 8, a right sealing seat 10 is arranged above the right extruded door panel 5, and a sealing strip 11 is provided at the edge of the right sealing seat 10; a connecting sleeve 12 is arranged at the middle part of the outer side of the left sealing seat 8 and the right sealing seat 10, and a mounting seat 13 is arranged on the side surface of the left seat extruded door panel 4 and the right extruded door panel 5 close to the connecting sleeve 12; a mounting cavity 14 is opened in the middle part of the mounting seat 13, the connecting sleeve 12 is inserted in the inside of the mounting cavity 14, and the inner wall of the mounting cavity 14 is connected with a threaded rod 15 through a bearing seat, and the threaded rod 15 is docked and inserted in the middle part of the connecting sleeve 12; the mounting seat 13 is provided with a mounting cavity 14 ... and the connecting sleeve 12 is inserted in the inside of the mounting cavity 14. A motor 16 connected to the threaded rod 15 is installed on the outer side of the mounting seat 13, and limiting grooves 17 are provided at both ends of the mounting seat 13. Both ends of the left sealing seat 8 and the right sealing seat 10 are connected to the limiting seat 18, and the limiting seat 18 is docked and inserted in the limiting groove 17. The threaded rod 15 and the connecting sleeve 12 are threadedly connected. The limiting grooves 17 are symmetrically distributed about the center line of the mounting seat 13. The limiting seat 18 and the limiting groove 17 are slidably connected. The sealing strip 11 is made of rubber, and the size of the sealing strip 11 matches the size of the docking groove 9. The extrusion head 6 on the left seat extrusion door panel 4 and the extrusion head 6 on the right extrusion door panel 5 are meshedly connected.

[0024] During specific implementation, when the hydraulic cylinder 7 drives the left seat extrusion door plate 4 and the right extrusion door plate 5 to close the slag extrusion, the threaded rod 15 connected to the output end is driven to rotate synchronously by starting the motor 16. Since the threaded rod 15 and the connecting sleeve 12 are threadedly connected, the connecting sleeve 12 can move outward along the installation cavity 14 with the rotation of the threaded rod 15, the left connecting sleeve 12 drives the left sealing seat 8 to move inward, and the right connecting sleeve 12 drives the right sealing seat 10 to move inward, and the moving left sealing seat 8 and the right sealing seat 10 are stably moved along the inside of the limiting groove 17 on the installation seat 13 through the limiting seats 18 connected at both ends until the left sealing seat 8 and the right sealing seat 10 are moved to the limit position. At this time, the docking groove 9 on the left sealing seat 8 is sleeved on the outside of the sealing strip 11 on the right sealing seat 10. The left sealing seat 8 and the right sealing seat 10 can be used to assist in sealing the material holding cavity 3 when the left seat extrusion door plate 4 and the right extrusion door plate 5 are closed, so that the hydraulic slag extrusion door for the slag scooping machine has an efficient sealing structure.

[0025] See also Figure 1 A guide groove 19 is provided on the inner wall edge of the slag extrusion door body 1, and guide blocks 20 are respectively connected to the two ends of the left seat extrusion door panel 4 and the right extrusion door panel 5, and the guide blocks 20 are inserted into the inside of the guide groove 19; a limit rod 21 passes through the middle of the guide block 20, and the two ends of the limit rod 21 are connected to the inner wall of the guide groove 19, and a spring 22 is sleeved on the outer side of the limit rod 21; one end of the spring 22 is connected to the guide groove 19, and the other end of the spring 22 is connected to the guide block 20, and a connecting block 23 is provided on the side of the left seat extrusion door panel 4 and the right extrusion door panel 5 close to the hydraulic cylinder 7, and the connecting block 23 is made of rubber, and the guide blocks 20 are symmetrically distributed about the center line of the left seat extrusion door panel 4, and the guide blocks 20 form a telescopic structure through the spring 22 and the guide groove 19.

[0026] During specific implementation, when the hydraulic cylinder 7 is started to drive the left and right extrusion door panels 4 and 5 to move to both sides and open, the left and right extrusion door panels 4 and 5 are stably moved inside the guide groove 19 along the limit rod 21 through the guide blocks 20 connected at both ends. At this time, the moving guide blocks 20 squeeze the spring 22 sleeved on the outside of the limit rod 21. As the left and right extrusion door panels 4 and 5 move, the rubber connecting blocks 23 connected to one side of the left and right extrusion door panels 4 and 5 will lightly fit the inner wall of the slag extrusion door body 1. When the hydraulic cylinder 7 is started to drive the left and right extrusion door panels 4 and 5 to move to both sides and open, the left and right extrusion door panels 4 and 5 are stably moved inside the guide groove 19 along the limit rod 21. At this time, the moving guide blocks 20 squeeze the spring 22 sleeved on the outside of the limit rod 21. When the cylinder 7 drives the left and right extrusion door panels 4 and 5 to move inward to squeeze out the slag, the connecting block 23 is separated from the inner wall of the slag extrusion door body 1, and at the same time, the left and right extrusion door panels 4 and 5 are stably moved along the guide groove 19 again through the guide block 20, and at this time, the squeezed spring 22 can also automatically reset to its initial shape. Through the mutual cooperation between the rubber material connecting block 23, the guide block 20 and the guide groove 19, the moving left and right extrusion door panels 4 and 5 can be auxiliary limited, thereby making the hydraulic slag extrusion door for the slag scooping machine more stable when in use.

[0027] To sum up, when using the high-efficiency sealed hydraulic slag squeezing door for the slag scooping machine, the slag squeezing door body 1 is installed in a designated position of the slag scooping machine. When the slag falls in, the hydraulic cylinders 7 on both sides of the slag squeezing door body 1 are started to drive the left seat squeezing door panel 4 and the right seat squeezing door panel 5 to move inward at the same time. Since the extrusion head 6 on the left seat squeezing door panel 4 and the extrusion head 6 on the right seat squeezing door panel 5 are meshed, the slag can be squeezed and crushed by the two groups of meshing extrusion heads 6, and finally the squeezed slag falls into the interior of the material holding chamber 3 and is discharged through the discharge port 2. This is the prior art and will not be elaborated here. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.
