[0015] A processing method for an edge grinding machine used for cement trench covers, comprising the following steps: S1: Adjust the spacing between the two limiting components and the height of the pressure plate according to the size of the cement trench cover. Start the servo motor to drive the double-acting screw to rotate, so that the drive rod can be threadedly connected to the double-acting screw. At this time, the two limiting components can be moved to the opposite side until the spacing between the two limiting components is adapted to the cement trench cover. Start the hydraulic lifting rod to drive the pressure plate to move up and down until the spacing between the pressure plate and the conveyor belt is adapted to the size of the cement trench cover. S2: Place the cement trench cover on top of the conveyor belt, continue to start the hydraulic lifting rod to press down the pressure plate. At this time, the roller in the inner cavity of the buffer component will contact the top of the cement trench cover. The buffer component will squeeze the spring to buffer the material. Stop the hydraulic lifting rod when the roller moves to the same axis as the pressure roller. S3: Start the conveyor belt, grinding wheel, pressure pump, and belt. After the conveyor belt starts, it will move to the right. After the grinding wheel starts, it can grind the edge of the cement trench cover.

When the grinding wheel grinds the edge of the cement trench cover, it can cool the cement trench cover and clean up the waste. After the belt starts, it will drive the pulley to rotate, so that the pressure wheel can cooperate with the conveyor belt to transport the cement trench cover. When the cement trench cover moves to the right, the grinding work of the cement trench cover is completed. S4: When the cement trench cover is being edged, the spray assembly will blow off the waste generated during the edge-grinding process, causing it to fall into the inner cavity of the water tank. The waste will be filtered by the filter screen, and the remaining water will be collected back into the inner cavity of the water tank. When there is a lot of waste, the screw is activated, allowing the back of the cleaning assembly to connect with its thread. At this time, the protrusion will move to the left. When the protrusion contacts the adapter post, it will move to the left. The adapter post will then move in the inner cavity of the adapter groove, and drive the shrink block to move in the inner cavity of the shrink groove. At this time, the waste on the top of the filter screen can be pushed into the discharge chute by the cleaning assembly and discharged. After the cleaning assembly is reset, the shrink groove will drive the adapter post to shrink through the shrink block, so that the adapter post can be blocked again in the inner cavity of the adapter groove.

[0016] Beneficial effects Compared with the prior art, the present invention provides an edge grinding machine and processing method for cement trench covers, which has the following beneficial effects: 1. The edge grinding machine and its processing method for cement trench covers, by activating the servo motor, can drive the bidirectional lead screw to rotate, so that the drive rods at both ends can be threadedly connected to the bidirectional lead screw, thereby driving the two limiting components to move to opposite sides. When grinding the cement trench cover, the grinding wheels at both ends can be driven to fit against the front and back of the cement trench cover according to its size, thus adapting to various sizes of cement trench covers for edge grinding work. Moreover, during edge grinding, it can prevent the cement trench cover from shaking, effectively ensuring the efficiency and accuracy of edge grinding.

[0017] 2. The edge grinding machine and its processing method for cement trench covers, through the water tank, can supply water to the spraying components via a pressure pump, water pipe and corrugated pipe. When grinding the edges of the cement trench covers, it can spray them, which can cool and reduce dust. This makes it convenient for the ground cement trench covers to be directly put into the next process without cleaning. In addition, the corrugated pipe can move with the movement of the limiting components, so that water can be supplied at all times.

[0018] 3. The edge grinding machine and its processing method for cement trench covers can filter the waste generated during edge grinding through the set filter screen, thereby filtering the water and collecting it back into the inner cavity of the water tank for water recycling. Through the movable cleaning component, the protrusion can be moved to the side, thereby opening the adapter pile and exposing the discharge chute, at which time the waste can be discharged through the discharge chute. This structure can automatically clean the water tank, thereby ensuring the normal water recycling work.

[0019] 4. The edge grinding machine and processing method for cement trench covers can drive the pressure plate to move up and down by activating the hydraulic lifting rod. When grinding the edge of the cement trench cover, the top of the cover can be limited. The pressure roller can be driven to move by the belt and pulley, thereby increasing the moving speed of the cement trench cover. When pressing down, the buffer component can buffer the cement trench cover and ensure its integrity during pressing. Attached Figure Description

[0026] A processing method for an edge grinding machine used for cement trench covers includes the following steps: S1: Adjust the distance between the two limiting components 3 and the height of the pressure plate 33 according to the size of the cement trench cover. Start the servo motor 7 to drive the bidirectional lead screw 6 to rotate, so that the drive rod 8 can be threadedly connected to the bidirectional lead screw 6. At this time, the two limiting components 3 can be moved to the opposite side until the distance between the two limiting components 3 is adapted to the cement trench cover. Start the hydraulic lifting rod 28 to drive the pressure plate 33 to move up and down until the distance between the pressure plate 33 and the conveyor belt 39 is adapted to the size of the cement trench cover. S2: Place the cement trench cover on top of the conveyor belt 39, continue to start the hydraulic lifting rod 28 to press down the pressure plate 33.

When the cement trench cover moves to the right, the grinding work of the cement trench cover is completed. S4: When the cement trench cover is being edged, the spray assembly 9 will blow off the waste generated during the edge grinding process, causing it to fall into the inner cavity of the water tank 10. The waste will be filtered by the filter screen 13, and the remaining water will be collected back into the inner cavity of the water tank 10. When there is a lot of waste, the screw 38 is activated, so that the back of the cleaning assembly 14 can be threaded to it. At this time, the protrusion 15 can be moved to the left. When the protrusion 15 contacts the adapter pin 25, it will be moved to the left. The adapter pin 25 will then move in the inner cavity of the adapter groove 20, and drive the shrink block 26 to move in the inner cavity of the shrink groove 22. At this time, the waste on the top of the filter screen 13 can be pushed into the discharge chute 21 by the cleaning assembly 14 and discharged. After the cleaning assembly 14 is reset, the shrink groove 22 drives the adapter pin 25 to shrink through the shrink block 26, so that the adapter pin 25 can be blocked again in the inner cavity of the adapter groove 20.

10. A processing method for an edge grinding machine for cement trench covers according to claim 1, characterized in that: The procedure includes the following steps: S1: Adjust the spacing between the two limiting components (3) and the height of the pressure plate (33) according to the size of the cement trench cover. Start the servo motor (7) to drive the double screw (6) to rotate, so that the drive rod (8) can be threadedly connected to the double screw (6). At this time, the two limiting components (3) can be moved to the opposite side until the spacing between the two limiting components (3) is adapted to the cement trench cover. Start the hydraulic lifting rod (28) to drive the pressure plate (33) to move up and down until the spacing between the pressure plate (33) and the conveyor belt (39) is adapted to the size of the cement trench cover. S2: Place the cement trench cover on top of the conveyor belt (39), continue to start the hydraulic lifting rod (28), press down the pressure plate (33), at this time the roller (37) in the inner cavity of the buffer assembly (35) will contact the top of the cement trench cover, the buffer assembly (35) will squeeze the spring (36) to buffer, and when the roller (37) moves to the same axis as the pressure wheel (34), stop the hydraulic lifting rod (28). S3: Start the conveyor belt (39), grinding wheel (4), pressurizing pump (19), and belt (31). After the conveyor belt (39) starts, it will move to the right. After the grinding wheel (4) starts, it can grind the side of the cement trench cover. After the pressurizing pump (19) starts, it will input the water in the inner cavity of the water tank (10) into the spray assembly (9) through the water pipe (17) and the corrugated pipe (18). When the grinding wheel (4) grinds the cement trench cover, it can cool the cement trench cover and clean up the waste. After the belt (31) starts, it will drive the pulley (32) to rotate, so that the pressing wheel (34) can cooperate with the conveyor belt (39) to transport the cement trench cover. When the cement trench cover moves to the right, the grinding work of the cement trench cover can be completed. S4: When the cement trench cover is being edged, the spray assembly (9) will blow away the debris generated during the edge-grinding process, causing it to fall into the inner cavity of the water tank (10). The debris will be filtered by the filter screen (13), and the remaining water will be collected back into the inner cavity of the water tank (10). When there is a lot of debris, the screw (38) is activated, so that the back of the cleaning assembly (14) can be threaded to it. At this time, the protrusion (15) can be moved to the left. When the protrusion (15) contacts the adapter post (25), it will push it towards When the device moves to the left, the adapter (25) will move in the inner cavity of the adapter groove (20) and drive the shrink block (26) to move in the inner cavity of the shrink groove (22). At this time, the waste on the top of the filter screen (13) can be pushed into the discharge trough (21) by the cleaning component (14) and discharged. After the cleaning component (14) is reset, the shrink groove (22) drives the adapter (25) to shrink through the shrink block (26), so that the adapter (25) can be blocked again in the inner cavity of the adapter groove (20).
