[0040] The working principle of embodiment 1 is as follows: when in use, the stirred concrete is first input into the storage cavity 30 for storage. At the same time, when the cam 34 is kept in a normal state, the raised part can be vertically upward, so that the cam 34 can squeeze the sealing plug 36 and insert it into the inside of the conveying pipe 37, thereby preventing the concrete inside the storage cavity 30 from flowing out. Subsequently, the mold 3 and the mold bottom plate 2 can be assembled and placed on the supporting base 29. Subsequently, the driving motor 24 is started to drive the screw rod 25 to rotate, and the connecting block 21 is threadedly sleeved on the outer ring of the screw rod 25, so that when the screw rod 25 rotates, it can drive the connecting block 21 to move, and the sleeve 17 is slidably sleeved on the outer ring of the guide rod 26, so that the collection cavity 16 can be supported to move along a straight line. At the same time, when When the conveying cavity 18 moves to align with the mold 3 at the center of the top of the support base 29, the hydraulic cylinder 19 can be started to drive the closing plate 20 to move downward, so that the closing plate 20 can be separated from the bottom end of the conveying cavity 18, and communicate with the inside of the conveying cavity 18 through the collecting cavity 16, and a discharge hole is provided at the bottom end of the conveying cavity 18, so that concrete can flow out from the inside of the conveying cavity 18, so that the concrete can flow into the inside of the mold 3. At the same time, the collecting cavity 16 continues to move toward the front end, so that the conveying cavity 18 can evenly pour concrete into the inside of the mold 3. At the same time, when the collecting cavity 16 moves toward the front end, it can drive the lower edge bracket 8 to move toward the front end at the same time, so that the toggle piece 10 can pass through the top of the mold bottom plate 2 and pass through the blocking of the mold bottom plate 2. , so that the mold bottom plate 2 can rotate toward the rear end, so that the toggle plate 10 can pass over the top of the mold bottom plate 2. Then, when the collecting cavity 16 moves to the front end to the limit position, the conveying cavity 18 can be vertically aligned with the internal front end of the mold 3, so that the interior of the mold 3 can be completely poured with concrete. At the same time, when the collecting cavity 16 moves to the front end to the limit position, it can drive the limit key 14 to move through the mold 3 at the top front end of the support base 29. The front end surface of the limit key 14 is inclined at 45°, so that the smoothness of the limit key 14 passing through the mold 3 can be improved. Then, when the collecting cavity 16 moves to the front end to the limit position, the limit key 14 can completely pass through the surface of the mold 3, and the elasticity of the first spring 13 will drive the limit key 1 4 is reset, so that the limit key 14 can be located on the front end of the mold 3, and when the collecting cavity 16 moves to the front end to the limit position, the toggle piece 10 can completely pass through the top of the mold bottom plate 2, so that the toggle piece 10 can be moved out from the top of the mold bottom plate 2, and then, the toggle piece 10 can be located at the front end of the mold bottom plate 2 at the center of the support base 29 in a vertical state, and then, the driving motor 24 can be started to drive the screw rod 25 to rotate in the opposite direction, so that the collecting cavity 16 can be displaced to the rear end. At this time, when the collecting cavity 16 moves to the rear end, the toggle piece 10 will not rotate to the front end due to the blocking of the blocking block 9, so that when the collecting cavity 16 moves to the rear end, the toggle piece 10 can push the mold bottom plate 2 at the center of the top of the support base 29 to the rear end, and at the same time,When the collecting cavity 16 drives the lower bracket 8 to move toward the rear end, the front bracket 11 can drive the limiting key 14 to move toward the rear end at the same time, so that the limiting key 14 can push the mold 3 at the front end of the top of the supporting base 29 to move toward the rear end, until the collecting cavity 16 moves to the limit position toward the rear end, the toggle plate 10 can push the mold 3 at the top center of the supporting base 29 to the rear end, and the mold 3 at the front end of the top of the supporting base 29 can move to the position of the previous mold 3, completing the pushing work of the two mold bottom plates 2 and the mold 3, so as to facilitate the casting of the next cement precast block, and when the collecting cavity 16 moves toward the rear end, it can drive the rack 15 to contact the gear 31, so that the rack 15 can drive the gear 31 to rotate, and when the collecting cavity 16 has not moved to the limit position toward the rear end, the collecting cavity 16 can move to the bottom end of the conveying pipe 37, and at the same time, when the gear 31 rotates, it can drive the worm 33 to rotate, and when the worm 33 rotates, it can drive the worm wheel 32 to rotate. The worm gear 32 can drive the raised part of the cam 34 to rotate downward, so that the sealing plug 36 will lose the extrusion of the cam 34 and move downward. The sealing plug 36 is slidably sleeved on the vertical guide rod 35, so that the sealing plug 36 can move downward in a straight line, so that the sealing plug 36 can be drawn out from the inside of the conveying pipe 37, so that the concrete inside the storage cavity 30 can flow into the inside of the collecting cavity 16 through the conveying pipe 37, and the work of replenishing the concrete inside the collecting cavity 16 is completed. Subsequently, when the screw rod 25 drives the collecting cavity 16 to move to the front end again, the rack 15 can pass through the bottom end of the gear 31, so that the gear 31 can drive the worm 33 to rotate in the opposite direction, so that the worm gear 32 can drive the cam 34 to rotate upward, so that the raised part of the cam 34 rotates to contact with the bottom end of the sealing plug 36, and the sealing plug 36 can be pushed upward until the sealing plug 36 can close the inner bottom end of the conveying pipe 37, preventing the concrete inside the accumulation cavity 30 from flowing out, and completing the work.

[0041] Example 2

[0042] On the basis of Example 1, Fig.10 As shown, the closing plate 20 includes a vibration rod 38 and an extended front frame 39 . The vibration rod 38 is symmetrically fixedly mounted at the bottom front end of the extended front frame 39 , and the extended front frame 39 is fixedly mounted at the front end of the closing plate 20 .

[0043] When implementing this embodiment, when the closing plate 20 moves downward, it can drive the vibration rod 38 to be inserted into the concrete accumulated inside the mold 3. At this time, the vibration rod 38 can be started so that the vibration rod 38 can be inserted into the concrete and vibrate. At the same time, the vibration rod 38 can be displaced along with the collection cavity 16 and displaced inside the mold 3, so that the concrete inside the mold 3 can be vibrated, thereby improving the density and uniformity of the concrete and reducing later manual intervention.
