[0031] The movable end of the hydraulic cylinder 13 is fixedly provided with an L-shaped connecting plate 4, the transverse protruding end of the L-shaped connecting plate 4 is detachably provided with a movable material blocking assembly 3, and the two sides of the top of the base 1 are fixedly provided with L-shaped splash-proof plates 2, and the movable material blocking assembly 3 is located between the opposite surfaces of the two splash-proof plates 2, and a splash-proof cavity is formed between the movable material blocking assembly 3, the machine bin 11 and the two splash-proof plates 2.

[0032] When the object is pressed down, the movable material blocking assembly 3 is first blocked in front of the two blocking blocks 12, so that the object is blocked, to prevent the splashing of the exploded object from polluting the environment and splashing the personnel, and when the pressing is finished, the movable material blocking assembly 3 will move upwards and will not be blocked in front of the two splash-proof plates 2, so as to facilitate the user to load and unload from the base 1, to avoid the splashing of the exploded object, and also will not affect the loading and unloading operation from the base 1, to ensure the operation convenience and improve the work efficiency.

[0033] As Figures 1 to 2As shown in the drawings, in this embodiment, the bottom of the L-shaped connecting plate 4 is welded with a horizontal connecting plate 41, and the horizontal connecting plate 41 is fixed on the top of the pressing plate 14.

[0034] As shown in the drawings, Figure 1 and Figure 4 As shown in the drawings, in this embodiment, the movable blocking assembly 3 includes a blocking plate one 31, a plastic film 32 and a blocking plate two 33, the plastic film 32 is fixed between the opposite surfaces of the blocking plate one 31 and the blocking plate two 33, and the elastic connecting pieces are installed between the two sides of the blocking plate one 31 and the blocking plate two 33.

[0035] As shown in the drawings, Figure 4 As shown in the drawings, in this embodiment, the elastic connecting piece includes a fixed block 34 welded on the blocking plate two 33, and a hole block 37 installed on the blocking plate one 31, the hole block 37 is slidingly installed with a guide rod 36 through a sliding hole formed on the hole block 37, the bottom end of the guide rod 36 is welded on the fixed block 34, the top end of the guide rod 36 is welded with a blocking disc 38 above the hole block 37, and the spring 35 is sleeved on the guide rod 36 between the opposite surfaces of the fixed block 34 and the hole block 37, when the blocking plate two 33 contacts the bottom of the base 1, if the hydraulic cylinder 13 continues to drive the L-shaped connecting plate 4 to move downward, the blocking plate two 33 contacts the top of the base 1, the L-shaped connecting plate 4 exerts pressure on the blocking plate one 31 to move downward to bend the movable blocking assembly 3, so that the movable blocking assembly 3 is not damaged under stress when the L-shaped connecting plate 4 is continuously elongated, at the same time, when the blocking plate one 31 moves downward, the hole block 37 compresses the spring 35, and under the elastic action of the spring 35, the distance between the blocking plate one 31 and the blocking plate two 33 is continuously expanded to reset to pull the plastic film 32 flat when the L-shaped connecting plate 4 is shortened and reset.

[0036] As shown in the drawings, Figures 1 to 2 As shown in the drawings, in this embodiment, the two sides of the top of the base 1 are fixed with the stop blocks 12, the distance between the front end surface of the stop block 12 and the front end surface of the base 1 is consistent with the thickness of the blocking plate one 31 and the blocking plate two 33, and the position of the movable blocking assembly 3 is limited by the stop block 12, when the movable blocking assembly 3 contacts the stop block 12, it means that the positioning rod 43 and the positioning hole 310 are coaxially arranged, which is helpful for conveniently installing the movable blocking assembly 3 and the L-shaped connecting plate 4.

[0037] As shown in the drawings, Figures 2 to 4As shown, in the embodiment, two sides of the top of the blocking plate one 31 and the top of the transversely protruding end of the L-shaped connecting plate 4 are provided with threaded hole grooves 39, and a bolt 42 is threadedly installed between the two threaded hole grooves 39 on the same side. The movable blocking assembly 3 and the L-shaped connecting plate 4 are fixed together in a detachable manner by screwing. When cleaning is needed, the movable blocking assembly 3 can be detached for comprehensive cleaning. After the movable blocking assembly 3 is detached, the splash-proof plate 2 and the machine bin 11 are completely exposed, which is more convenient for cleaning the machine bin 11 and the splash-proof plate 2, thereby improving the cleaning effect.

[0038] As shown in the drawings, Figures 2 to 4 As shown, in the embodiment, the middle of the transversely protruding end of the L-shaped connecting plate 4 is fixed with a positioning rod 43, and the middle of the top of the blocking plate one 31 is provided with a positioning hole 310 for clamping the positioning rod 43. The positioning rod 43 enters the positioning hole 310 for positioning, so that the blocking plate one 31 and the threaded hole groove 39 on the L-shaped connecting plate 4 are self-aligned.

[0039] In use, the process of installing the movable blocking assembly 3 on the L-shaped connecting plate 4 is as follows: the movable blocking assembly 3 is placed on the base 1 between the two splash-proof plates 2, and the position of the movable blocking assembly 3 is limited by the stop block 12. When the movable blocking assembly 3 is in contact with the stop block 12, it means that the positioning rod 43 and the positioning hole 310 are coaxially arranged, which is helpful for conveniently installing the movable blocking assembly 3 and the L-shaped connecting plate 4.

[0040] The hydraulic cylinder 13 extends to drive the transversely connecting plate 41 to move downward, thereby driving the L-shaped connecting plate 4 to press downward on the top of the movable blocking assembly 3, and making the positioning rod 43 enter the inside of the positioning hole 310 for clamping. Further, the movable blocking assembly 3 and the L-shaped connecting plate 4 are fixed together. The bolt 42 is screwed into the two threaded hole grooves 39 on the same side to fix the movable blocking assembly 3 on the L-shaped connecting plate 4.

[0041] The object is placed on the top of the base 1 and below the pressing plate 14. The hydraulic cylinder 13 drives the pressing plate 14 to move downward to press the object through the pressing plate 14. When the pressing plate 14 is in contact with the object, the bottom end of the blocking plate two 33 is in contact with the top of the base 1 to block the front side between the two splash-proof plates 2. When the object is pressed and explodes, the splashed objects are blocked between the two splash-proof plates 2, the movable blocking assembly 3 and the machine bin 11, preventing the object from splashing and polluting the environment and splashing and injuring the personnel.

[0042] When the blocking plate two 33 is in contact with the bottom of the base 1, if the hydraulic cylinder 13 continues to drive the L-shaped connecting plate 4 to move downward, the blocking plate two 33 is in contact with the top of the base 1, and the L-shaped connecting plate 4 applies pressure to the blocking plate one 31 to move downward to bend the movable blocking assembly 3.

[0043] Meanwhile, when the blocking plate one 31 moves downward, the hole block 37 drives the spring 35 to compress, and when the L-shaped connecting plate 4 is shortened and reset, the distance between the blocking plate one 31 and the blocking plate two 33 is continuously expanded and reset under the elastic effect of the spring 35, and the plastic film 32 is pulled flat.

[0044] It should be understood that the use of these embodiments is only for the purpose of illustrating the present application and is not intended to limit the scope of protection of the present application. In addition, it should also be understood that after reading the technical content of the present application, those skilled in the art can make various modifications, modifications and / or variations to the present application, and all these equivalent forms also fall within the protection scope defined by the claims attached to the present application.
