[0024] like Figure 1-5As shown, the utility model provides a technical solution: a hydraulic push rod device for a bottom material discharge port, comprising a bottom material bin 1, a radar level meter 2 is fixed on the top of the bottom material bin 1, one end of an L-shaped fixing rod 3 is fixedly connected to the bottom of the bottom material bin 1, the other end of the L-shaped fixing rod 3 is fixedly connected to an electro-hydraulic push rod 4, and a dustproof mechanism 5 is arranged on the surface of the electro-hydraulic push rod 4. The dustproof mechanism 5 comprises: a receiving port gate 51, a transmission rod 52, a right piston block 53, a pull rope 54, a roller 55, a left piston block 56, a spring 1 57, a hollow column 58, a hollow channel cylinder 59, a fixing plate 510, a spring 2 511, a blocking plate 512, an air inlet filter 513, and an air outlet filter 514.

[0025] The surface of the electro-hydraulic push rod 4 is fixedly connected to the surface of a hollow column 58. The number of the hollow columns 58 is two, and the two hollow columns 58 are arranged symmetrically. The inner wall of the hollow column 58 is rotatably connected to a roller 55.

[0026] The output shaft of the electro-hydraulic push rod 4 is fixedly connected with a receiving port gate 51. When in use, the radar level meter 2 is used to detect the material level in the bottom paving silo 1. The electro-hydraulic push rod 4 is controlled according to the material level to adjust the opening of the receiving port gate 51, thereby realizing automatic discharge of the bottom paving material. The top of the receiving port gate 51 is fixedly connected with the bottom of a transmission rod 52, and the top of the transmission rod 52 is fixedly connected with the bottom of a right piston block 53. The top of the right piston block 53 is fixedly connected with one end of a pull rope 54, and the other end of the pull rope 54 is fixedly connected to the top surface of a left piston block 56 through a roller 55. The bottom surface of the left piston block 56 is fixedly connected with one end of a spring 57, and the other end of the spring 57 is fixedly connected to the bottom of the inner wall of the left hollow column 58.

[0027] The bottom of the hollow column 58 is fixedly connected to the surface of the hollow channel cylinder 59, and the inner wall of the hollow channel cylinder 59 is fixedly connected to a fixing plate 510. One end of a spring 2 511 is fixedly connected to the surface of the fixing plate 510, and the other end of the spring 2 511 is fixedly connected to a blocking plate 512. An air inlet filter 513 is fixedly connected to the side of the inner wall of the hollow channel cylinder 59 close to the fixing plate 510, and an air outlet filter 514 is fixedly connected to the side of the inner wall of the hollow channel cylinder 59 close to the blocking plate 512. The air hits the blocking plate 512, and the blocking plate 512 stretches the spring 2 511. The air is output through the air outlet filter 514 and blows to the connector of the output shaft of the electro-hydraulic push rod 4 to prevent dust from entering the output shaft of the electro-hydraulic push rod 4. The air is squeezed through the blocking plate 512 on the inner wall of the hollow channel tube 59 to blow the connecting head of the output shaft of the electric-hydraulic push rod 4. Regardless of the reciprocating movement of the electric-hydraulic push rod 4, the air is blown to the connecting head of the output shaft of the electric-hydraulic push rod 4 to prevent dust from entering through the connecting head of the output shaft of the electric-hydraulic push rod 4. At the same time, the hollow channel tubes 59 on both sides are unidirectional for air to pass, so that when the inner wall of the hollow column 58 absorbs external air, it uses the hollow channel tube 59 away from one end of the electric-hydraulic push rod 4 to prevent dust from being adsorbed on the air outlet filter 514 on the inner wall of the hollow channel tube 59 close to the end of the electric-hydraulic push rod 4 and being blown onto the connecting head of the output shaft of the electric-hydraulic push rod 4.

[0028] The transmission rod 52 passes through the bottom of the right hollow column 58 , and the transmission rod 52 is connected to the bottom piston of the right hollow column 58 , and the transmission rod 52 and the inner wall of the hollow column 58 reciprocate up and down.

[0029] The receiving port gate 51 contacts the surface of the bottom discharge port of the bottom silo 1, thereby blocking the discharge port.

[0030] The surface of the right piston block 53 is connected to the inner wall piston of the right hollow column 58, and the surface of the left piston block 56 is connected to the inner wall piston of the left hollow column 58. The right piston block 53 and the inner wall of the right hollow column 58 move back and forth up and down, so that the air on the inner wall of the right hollow column 58 is squeezed and pulled.

[0031] An arrow indicating the direction of air flow is fixed on the surface of the hollow channel tube 59 to facilitate the installation direction of the hollow channel tube 59. At the same time, the hollow channel tube 59 can only allow air to flow in the direction indicated by the arrow.

[0032] The side of the blocking plate 512 close to the spring 2 511 contacts the protruding ring on the inner wall of the hollow channel tube 59, thereby blocking the air.

[0033] In the utility model, the radar level meter 2 is used to detect the material level in the bottom material bin 1, and the electro-hydraulic push rod 4 is controlled according to the material level to adjust the opening of the receiving port gate 51, thereby realizing automatic discharge of the bottom material.

[0034] When the output shaft of the electro-hydraulic push rod 4 extends out, the output shaft of the electro-hydraulic push rod 4 drives the receiving port gate 51 to move away from the hollow column 58, and the receiving port gate 51 drives the transmission rod 52 to move away from the hollow column 58, and the transmission rod 52 drives the right piston block 53 to move downward, and the right piston block 53 moves downward so that the air at the bottom of the inner wall of the right hollow column 58 is squeezed, and the air passes through the inner wall of the hollow channel tube 59 on the left side of the bottom of the right hollow column 58, and the air hits the blocking plate 512, and the blocking plate 512 stretches the spring 2 511, and the air is output through the air outlet filter 514 to blow to the connector of the output shaft of the electro-hydraulic push rod 4 to prevent dust from passing through. The piston block 53 on the right side drives the piston block 56 on the left side to move upward through the pull rope 54, and the piston block 56 on the left side forms a negative pressure at the bottom of the inner wall of the left hollow column 58. The blocking plate 512 on the inner wall of the hollow channel tube 59 on the right side of the bottom of the left hollow column 58 is squeezed by the outside air and tightly contacts the inner wall of the hollow channel tube 59. The air can only move unidirectionally in the hollow channel tube 59 in the direction of the arrow, so that the outside air passes through the hollow channel tube 59 on the left side of the bottom of the left hollow column 58. The hollow channel tube 59 is pushed by the outside air to push the blocking plate 512 into the inner wall of the left hollow column 58.

[0035] When the output shaft of the electro-hydraulic push rod 4 contracts, the output shaft of the electro-hydraulic push rod 4 drives the receiving port gate 51 to move toward the direction close to the hollow column 58, and the receiving port gate 51 drives the transmission rod 52 to move upward. At this time, the pull rope 54 no longer tightens the left piston block 56, and the spring 1 57 drives the left piston block 56 to move downward. At this time, positive pressure is formed at the bottom of the inner wall of the left hollow column 58, and the hollow channel cylinder 59 on the right side of the bottom of the left hollow column 58 is squeezed by air. The air is squeezed through the blocking plate 512 on the inner wall of the hollow channel cylinder 59 to blow the connector of the output shaft of the electro-hydraulic push rod 4;

[0036] At the same time, the hollow channel tubes 59 on both sides are unidirectional for passing air, so that when the inner wall of the hollow column 58 absorbs external air, it uses the hollow channel tube 59 far away from the end of the electro-hydraulic push rod 4 to prevent dust from being adsorbed on the air outlet filter 514 on the inner wall of the hollow channel tube 59 close to the end of the electro-hydraulic push rod 4 and being blown onto the connecting head of the output shaft of the electro-hydraulic push rod 4.

[0037] The connecting head of the output shaft of the electric-hydraulic push rod 4 is blown regardless of the reciprocating movement of the electric-hydraulic push rod 4, thereby preventing dust from entering through the connecting head of the output shaft of the electric-hydraulic push rod 4.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
