[0046] See also Figure 1 , Figure 2 and Figure 7 The two hydraulic push rods 433 move the two telescopic branches 431 in the blanking frame 41 through the two traction branches 432. The two telescopic branches 431 gradually separate and connect the multiple discharge pipes 42 with the blanking frame 41 in sequence from the least to the most.

[0047] During specific operation, the lower end of the discharge pipe 42 is equipped with a sealing valve (not shown in the figure). According to the amount of mixed refractory materials, a corresponding number of discharge pipes 42 are selected to work simultaneously, which can not only improve the efficiency of loading, but also effectively control the input of loading labor, thereby effectively controlling the cost of loading and transportation. The two hydraulic push rods 433 are connected to the existing hydraulic pump, and then the two hydraulic push rods 433 are started. The two hydraulic push rods 433 drive the lower ends of the two telescopic branch chains 431 to separate through the two traction branch chains 432 until the lower ends of the two telescopic branch chains 431 move to the corresponding positions, thereby connecting the corresponding number of discharge pipes 42 with the blanking frame 41, and then the corresponding number of collection bags are placed on the working discharge pipes 42 and the sealing valves on the discharge pipes 42 are opened.

[0048] See also Figure 6 , Figure 7 and Fig.11 The telescopic branch chain 431 includes a first U-shaped frame 4311 which is hinged downward in the blanking frame 41 and located at the top corner. A second U-shaped frame 4313 which is opened downward is slidably connected in the first U-shaped frame 4311, and a first connecting spring 4312 is installed between the two. A rectangular plate 4315 is slidably connected in the second U-shaped frame 4313, and a second connecting spring 4314 is installed between the two. The lower end of the rectangular plate 4315 is rotatably connected to a movable roller 4316.

A traction rod 4324 is hinged on the second slider 4323 and is slidably connected to the corresponding side wall of the blanking frame 41. A traction plate 4325 is installed together with the end of the traction rod 4324 away from the second slider 4323 and the moving end of the hydraulic push rod 433.

[0050] See also Figure 6 Sliding grooves are provided at the inner ends of the two side walls of the first U-shaped frame 4311 and the inner ends of the two side walls of the second U-shaped frame 4313, sliding bars are installed at the outer ends of the two side walls of the second U-shaped frame 4313, and sliding bars are also installed on the two end surfaces of the rectangular plate 4315 that are slidably connected to the second U-shaped frame 4313, and the sliding bars are slidably connected to the sliding grooves.

[0051] During specific operation, in the initial state, the first connecting spring 4312 and the second connecting spring 4314 are both in a normal state, the first U-shaped frame 4311, the second U-shaped frame 4313 and the rectangular plate 4315 are in an inclined state, and the two moving rollers 4316 are in a close contact state, thereby blocking the path of the multiple discharge pipes 42 for dropping materials. When loading, the two hydraulic push rods 433 are started, and the two hydraulic push rods 433 drive the two traction rods 4324 to separate through the two traction plates 4325, and the two traction rods 4324 drive the two rectangular plates 4315 to separate through the second slider 4323 and the traction rod 4324, until the two rectangular plates 4315 drive the two moving rollers 4316 to move to the desired position. This process During the process, the rectangular plate 4315 is subjected to force to slide in the sliding groove on the second U-shaped frame 4313 through the corresponding sliding bar, and at the same time squeezes the second connecting spring 4314. The second U-shaped frame 4313 is subjected to force to slide in the sliding groove on the first U-shaped frame 4311 through the corresponding sliding bar, and at the same time squeezes the first connecting spring 4312, thereby changing the overall length of the first U-shaped frame 4311, the second U-shaped frame 4313 and the rectangular plate 4315 to meet the working requirements. During loading, the mixed refractory material falls from the guide frame 31 to the telescopic branch chains 431 on both sides. The two telescopic branch chains 431 guide the mixed refractory material and discharge it through a corresponding number of discharge pipes 42 and fall into the corresponding collection bag.

A lifting plate 481 is commonly installed on the left ends of the transverse sections of the plurality of anti-blocking rods 482, and the lifting plate 481 is installed at the lower end of the lifting rod 45.

[0054] During specific operation, when the mixed refractory material is loaded, the second drive motor 33 drives the cam 46 to rotate, and the cam 46 drives the corresponding two guide rods 49 to move through the two guide grooves 47, so that the two guide rods 49 move back and forth up and down, and the two guide rods 49 drive the lifting rod 45 to move back and forth up and down, and the lifting rod 45 drives the lifting plate 481 to move back and forth up and down, and the lifting plate 481 drives multiple anti-blocking rods 482 to move up and down in the corresponding discharge pipe 42 to avoid blockage in the discharge pipe 42 during the loading process. The baffle film 483 is made of elastic rubber. The baffle film 483 not only provides conditions for the up and down movement of the anti-blocking rod 482, but also seals the discharge pipe 42 to avoid the mixed refractory material from spilling, thereby ensuring that all the mixed refractory materials can be collected.

[0055] After the corresponding number of collecting bags are filled, close the sealing valve on the discharge pipe 42, separate the collecting bags filled with the mixed refractory material from the discharge pipe 42, connect the unused collecting bags to the discharge pipe 42, open the sealing valve on the discharge pipe 42, and continue to bag the collecting bags with the discharge pipe 42. Repeat this step until all the mixed refractory materials are bagged and the bagging and transportation of the mixed refractory materials is completed.
