[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] The present application discloses a waste alloy hydraulic baler, referring to Figure 1-3 , including a compression box 1, a hopper 2, a first compression assembly 3, a second compression assembly 4, a third compression assembly 5, and a shearing assembly 6;

[0033] The compression box 1 is a hollow box with an opening on the top. One end of the compression box 1 is hinged to the hopper 2. The size of the opening occupies two-thirds of the upper surface of the compression box 1. The hopper 2 is hinged to the box wall of the short side of the compression box 1.

[0034] The first compression assembly 3 includes a first hydraulic cylinder 31, a pressure cover plate 32 and a fixed platform 33. The fixed platform 33 is installed above the compression box 1. The fixed platform 33 is hinged to the first hydraulic cylinder 31. The pressure cover plate 32 is hinged at the opening of the compression box 1. A limit block 8 is installed on the pressure cover plate. There is a groove in the middle of the limit block 8. The piston rod of the first hydraulic cylinder 31 is hinged to the groove of the limit block 8. The fixed platform 33 is installed on the remaining one-third of the upper surface of the compression box 1. By driving the first hydraulic cylinder 31, the pressure cover plate 32 can be rotated to a certain extent around the hinge axis at the opening of the compression box 1, thereby compressing the waste alloy material downward and closing the opening of the compression box 1, or lifting up to open the opening of the compression box 1. The pressure cover plate 32 compresses the waste alloy material downward as the first level of compression, and the limit block 8 limits the downward pressure of the pressure cover plate 32.

[0035] The second compression assembly 4 includes a second hydraulic cylinder 41 and a main push block 42. The main push block 42 is slidably installed inside the compression box 1. The second hydraulic cylinder 41 is fixedly installed on the side wall of the compression box 1. The piston rod of the second hydraulic cylinder 41 passes through the side wall of the compression box 1 and is connected to the main push block 42. The second hydraulic cylinder 41 can drive the main push block 42 to move along the long side direction of the compression box 1, thereby pushing the waste alloy toward the hopper for the second stage of compression.

[0036] The third compression assembly 5 includes a third hydraulic cylinder 51 and a push block 52. The push block 52 is slidably installed inside the compression box 1. The third hydraulic cylinder 51 is fixedly installed on the side wall of the compression box 1. The piston cylinder of the third hydraulic cylinder 51 passes through the side wall of the compression box 1 and is connected to the push block 52. The third hydraulic cylinder 51 can drive the push block 52 to move along the short side direction of the compression box 1 to perform the third stage compression on the waste alloy. After the third stage compression is completed, the compression process ends.

[0037] The shearing assembly 6 includes a shearing hydraulic cylinder 61, a shearing knife 62, a rotating machine table 63 and a knife holder 64. The shearing hydraulic cylinder 61 and the rotating machine table 63 are fixedly installed on the side of the compression box 1. The knife holder 64 is rotatably connected in the middle of the rotating machine table 63. The shearing knife 62 is slidably connected to the knife holder 64. The knife holder 64 can rotate around the central axis in the middle of the rotating machine table 63.

[0038] Reference Figure 2 and Figure 4A discharge port 10 is provided on the side wall of the compression box 1, a gate block 11 is slidably installed at the discharge port 10, a gate hydraulic cylinder 12 is fixedly installed on the side wall of the compression box 1, and the piston rod of the gate hydraulic cylinder 12 is connected to the gate hydraulic cylinder 12. The gate hydraulic cylinder 12 can control the gate block 11 to move at the discharge port 10 to control the opening or closing of the discharge port 10. When compressing, the gate hydraulic cylinder 12 controls the gate block 11 to block the discharge port 10, and a closed compression chamber is formed in the compression box 1. After compression, the gate hydraulic cylinder 12 controls the gate block 11 to move away from the discharge port 10. At this time, the piston rod of the third hydraulic cylinder 51 continues to drive the side push block 52 to move, and the side push block 52 pushes the waste alloy block out of the discharge port 10.

[0039] Reference Figure 2 A discharge pipe 13 is installed outside the discharge port 10. The discharge pipe 13 ensures that the waste alloy block moves along a predetermined direction, making it convenient for the transportation tool below to receive the waste alloy block, and also ensures that the shearing assembly 3 can smoothly shear the waste alloy block.

[0040] Reference Figure 2 and Figure 7 The discharge pipe 13 is provided with a knife feed groove 14 to facilitate the shearing of the waste alloy block by the shearing knife.

[0041] Reference Figure 6 The knife holder 64 is provided with four knife slots for placing the shearing knives 62 .

[0042] Reference Figure 6 and Figure 7 The piston rod of the shearing hydraulic cylinder 61 and the handle of the shearing knife 62 can cooperate with each other and both have two threaded holes, and the piston rod of the shearing hydraulic cylinder 61 and the shearing knife 62 can be connected by bolts.

[0043] Reference Figure 6 The shear knives 62 are high-speed steel HSS shear blades, tungsten carbide shear blades, carbon tool steel shear blades and D2 high-alloy steel shear blades. High-speed steel HSS shear blades are suitable for shearing softer metals such as brass and aluminum, and can remain stable at high temperatures. Carbon tool steel is suitable for cutting ordinary low-carbon cold-rolled plates and standard A3 plates. D2 high-alloy steel shear blades perform well in cutting hard metals, stainless steel and alloy metals. Choosing the right shear blade material can improve shearing efficiency, extend the service life of the blade, and ensure shearing quality.

[0044] 9. Reference Figure 1-4The compression box 1 is a rectangular box body, the shearing assembly 6 is installed at the side of the long side end face of the compression box 1, the hopper 2 is hinged at the upper end face of the short side of the compression box 1, the second hydraulic cylinder 41 is installed at the end face of the compression box 1 opposite to the hopper 2 installation position, the third hydraulic cylinder 51 is installed at the side end face opposite to the shearing assembly 6, the opening position of the discharge port 10 is opposite to the third hydraulic cylinder 51, and a control console 7 is also installed next to the shearing assembly 6. The control console 7 has five control levers, which respectively control the corresponding hydraulic cylinders.

[0045] The working principle of the example of the present application is as follows: in the normal state, the pressure cover plate 32 is in a downward pressure state, the hopper 2 is located on the ground, and the gate block 11 is blocked at the position of the discharge port 10; first, fill the scrap alloy material into the hopper 2, and turn the corresponding control lever 1 on the control console 7 to start the first hydraulic cylinder 31. The piston rod of the first hydraulic cylinder 31 contracts, and the piston rod of the first hydraulic cylinder 31 pulls the pressure cover plate 32 to rotate upward around the hinge axis at the opening of the compression box 1. The pressure cover plate 32 drives the hopper 2 to rotate around the hinge axis between the hopper 2 and the compression box 1 through the iron chain 9. The hopper 2 is tilted and lifted, and the waste alloy material is poured into the compression box 1 by the hopper 2. The corresponding control rod of the console 7 is toggled, and the first hydraulic cylinder 31 pushes the piston rod to move. The piston rod extends and drives the pressure cover plate 32 to rotate downward around the hinge axis at the opening of the compression box 1. The pressure cover plate 32 drives the limit block 8 to move downward. When the limit block 8 is attached to the upper surface of the compression box 1, the pressure cover plate 32 stops rotating, and the waste alloy material is compressed at the first level. In fact, the hopper 2 is put back on the ground, and the next batch of waste alloy materials can be added to the hopper 2 during the compression process;

[0046] The control rod corresponding to the control console 7 is turned to start the second hydraulic cylinder 41, and the piston rod of the second hydraulic cylinder 41 pushes the main push block 42 to move, and the main push block 42 pushes the waste alloy material to the side wall of the compression box 1 to perform the second stage compression;

[0047] The control rod 3 corresponding to the control console 7 is turned to start the third hydraulic cylinder 51. The piston rod of the third hydraulic cylinder 51 pushes the side push block 52 to move. The side push block 52 pushes the waste alloy material toward the gate block 11 to perform the third level of compression. The waste alloy material is compressed into a rectangular waste alloy block, and the compression process ends.

[0048] The control rod 4 corresponding to the control console 7 is turned to start the gate hydraulic cylinder 12, and the piston rod of the gate hydraulic cylinder 12 drives the gate block 11 to move, and the gate block 11 is moved to the discharge port 10, and the discharge port 10 is opened. The control rod 3 corresponding to the control console 7 is turned to start the third hydraulic cylinder 51, and the piston rod of the third hydraulic cylinder 51 drives the side push block 52 to push the waste alloy block out of the discharge port 10, and the waste alloy block enters the discharge pipe 13 from the discharge port 10;

[0049] The worker rotates the tool holder 64 according to the material of the scrap alloy material, selects a suitable shearing knife 62, rotates the shearing knife 62 to align with the piston rod of the shearing hydraulic cylinder 61, and turns the corresponding control lever five of the control console 7 to start the shearing hydraulic cylinder 61, so that the piston rod of the shearing hydraulic cylinder 61 and the handle of the shearing knife 62 cooperate with each other. After the cooperation is completed, the bolt is screwed in to connect the piston rod of the shearing hydraulic cylinder 61 and the shearing knife 62 together, and the shearing hydraulic cylinder 61 is continued to be started. The piston rod of the shearing hydraulic cylinder 61 pushes the shearing knife 62 into the feed groove 14 and continues to move to shear the scrap alloy block. The sheared scrap alloy block enters the transport vehicle along the discharge pipe 13.
