[0019] The third bevel gear 306 is provided with a driving gear 402 fixedly mounted on the bottom of the third housing 303, and the driving gear 402 is rotatably connected to the inner wall of the annular fixed frame 401, and the rotating baffle 209 is rotatably connected to the inner wall of the annular fixed frame 401, and a mounting groove 403 is provided in the middle of the rotating baffle 209 corresponding to the position of the driving gear 402, and a fixed shaft 404 is fixedly mounted on the inner wall of the mounting groove 403, and a rotating tooth 405 is rotatably connected to the surface of the rotating tooth 405, and a limiting sleeve 407 for limiting the rotation of the rotating tooth 405 is rotatably connected to the surface of the rotating tooth 405. , and the limiting sleeve 407 is rotatably connected to the surface of the fixed shaft 404, the two ends of the rotating tooth 405 are respectively fixedly installed with a torsion spring 406, and the torsion spring 406 is fixedly installed on the inner wall of the installation groove 403, the rotating tooth 405 is a teardrop-shaped structure, and the limiting sleeve 407 is a V-shaped structure, and the inner wall of one end of the limiting sleeve 407 is tightly fitted with the surface of the rotating tooth 405, and the bottom of the annular fixed frame 401 corresponding to the position of the limiting sleeve 407 is provided with a guide groove 40 8, and the surface of the limiting sleeve 407 is closely fitted with the inner wall of the guide groove 408, a through groove 409 is opened in the middle of the guide groove 408, and an elastic sheet 410 for assisting the rotation of the limiting sleeve 407 is fixedly installed on the inner wall of the through groove 409, the movable end of the elastic sheet 410 is tilted upward, and there is a gap between the movable end of the elastic sheet 410 and one end of the inner wall of the through groove 409, the width of the through groove 409 is greater than the width of the limiting sleeve 407, and the length of the through groove 409 is greater than the length of the elastic sheet 410; When the above structure is in use, when the second bevel gear 305 rotates forward, that is, when the pouring operation is performed, the third bevel gear 306 rotates in the reverse direction, and drives the driving gear 402 to rotate in the reverse direction, and the driving gear 402 drives the rotating baffle 209 to rotate by rotating the teeth 405 in cooperation with the fixed shaft 404, until the rotating baffle 209 drives the through hole 211 to coincide with the through hole 211 of the fixed baffle 208, so that when the first driving shaft 102 rotates clockwise, the through hole 211 in the middle of the fixed baffle 208 and the rotating baffle 209 is coincident with each other. The holes 211 overlap with each other. On the contrary, when the second bevel gear 305 rotates in the opposite direction, that is, the third bevel gear 306 rotates forward, the third bevel gear 306 drives the rotating baffle 209 to rotate forward through the driving gear 402 in cooperation with the rotating teeth 405 and the fixed shaft 404, and the through hole 211 in the middle of the rotating baffle 209 and the through hole 211 in the middle of the fixed baffle 208 are staggered, so that a sealing structure is formed at the bottom of the second discharge pipe 203, thereby achieving self-sealing during stirring and achieving communication during pouring.

[0020] Working principle: When in use, the invention realizes mixing and pouring by driving the first driving shaft 102 and the first conveying blade 103 to rotate through the forward and reverse motors, wherein the main function of the first driving shaft 102 driving the first conveying blade 103 to rotate forward and reverse is to assist other mixing equipment in performing material mixing operations on concrete. When the forward and reverse motors drive the first driving shaft 102 to rotate clockwise, the first driving shaft 102 drives the first conveying blade 103 to rotate to assist in mixing concrete. At the same time, the clockwise rotation of the first driving shaft 102 drives the first bevel gear 304 to rotate clockwise, and the first bevel gear 304 drives the second bevel gear 305 and the third bevel gear 306 respectively. The gear 306 rotates, and the second bevel gear 305 and the third bevel gear 306 rotate in opposite directions. When the first drive shaft 102 rotates clockwise through the first bevel gear 304 to drive the second bevel gear 305 to rotate forward, the second bevel gear 305 drives the second drive shaft 206 to rotate forward, and the second drive shaft 206 drives the second conveying blade 207 to rotate forward, and the concrete entering the inside of the tee pipe 202 through the first discharge pipe 201 is conveyed to the second discharge pipe 203, and the concrete passes through the overlapping through holes 211 in the fixed baffle 208 and the rotating baffle 209, and is discharged from the bottom of the second discharge pipe 203 to complete the pouring work; When the forward and reverse motor drives the first driving shaft 102 to rotate counterclockwise, the first driving shaft 102 drives the first bevel gear 304 to rotate counterclockwise, and the first bevel gear 304 drives the second bevel gear 305 to rotate in the opposite direction. At this time, the through holes 211 in the middle of the fixed baffle 208 and the rotating baffle 209 are intertwined with each other, and the communication state at the bottom of the second discharge pipe 203 is closed, that is, when the second bevel gear 305 drives the second driving shaft 206 and the second conveying blade 207 to rotate in the opposite direction, the second conveying blade 207 will convey the concrete in the first discharge pipe 201 and the three-way pipe 202 to the first return pipe 204, and the concrete is conveyed upward. To the second return pipe 205, and then return to the mixing chamber 101 through the third return pipe 210. Since the concrete is transported upward in the first return pipe 204, it can be understood that the concrete is transported upward by the second transport blade 207, and then returns to the mixing chamber 101 through the third return pipe 210. Since the inner diameter of the first return pipe 204 is smaller than that of the mixing chamber 101, that is, the cross section is smaller, and during the surging of the concrete, the bubbles mixed in the concrete will contact with the air and release the bubbles into the air, thereby avoiding the problem of the mixed bubbles affecting the strength and durability of the concrete sandwich block; When the second bevel gear 305 rotates forward, that is, during the pouring operation, the rotation direction of the third bevel gear 306 is opposite to that of the second bevel gear 305, that is, the third bevel gear 306 rotates in the opposite direction, and when the third bevel gear 306 rotates in the opposite direction, the third bevel gear 306 will drive the driving gear 402 to rotate in the opposite direction, and the driving gear 402 drives the rotating baffle 209 to rotate by rotating the teeth 405 in cooperation with the fixed shaft 404, until the rotating baffle 209 drives the through hole 211 to coincide with the through hole 211 of the fixed baffle 208, so that When the first driving shaft 102 rotates clockwise, the through holes 211 in the middle of the fixed baffle 208 and the rotating baffle 209 coincide with each other. On the contrary, when the second bevel gear 305 rotates in the opposite direction, that is, when the third bevel gear 306 rotates forward, the third bevel gear 306 drives the rotating baffle 209 to rotate forward through the driving gear 402 in cooperation with the rotating teeth 405 and the fixed shaft 404, and the through holes 211 in the middle of the rotating baffle 209 and the through holes 211 in the middle of the fixed baffle 208 are interlaced, so that a sealing structure is formed at the bottom of the second discharge pipe 203; The function of the limiting sleeve 407 is that when the driving gear 402 rotates, the inner wall of the limiting sleeve 407 and the driving gear 402 at one end in the rotation direction will fit tightly with the rotating tooth 405. At the same time, since the bottom of the limiting sleeve 407 fits tightly with the inner wall of the guide groove 408, when the driving gear 402 rotates, the driving gear 402 will move the rotating tooth 405. Since the limiting sleeve 407 and the inner wall of the driving gear 402 at one end in the rotation direction will fit tightly with the rotating tooth 405, the limiting sleeve 407 can be used to prevent the rotating tooth 405 from rotating. The bottom of 07 is tightly fitted with the inner wall of the guide groove 408, that is, the limit sleeve 407 cannot rotate around the fixed shaft 404, and the limit sleeve 407 prevents the rotating tooth 405 from rotating in one end of the driving gear 402. That is, when the driving gear 402 rotates, the rotating tooth 405 cooperates with the fixed shaft 404 to drive the limit sleeve 407 and the rotating baffle 209 to rotate until the limit sleeve 407 moves to the position of the elastic sheet 410, wherein the movable end of the elastic sheet 410 is tilted upward, which makes the limit sleeve 407 The angle position of the bottom of the sleeve 407 will be blocked by the elastic sheet 410, and under the action of the elastic sheet 410, one corner of the limiting sleeve 407 moves to the gap position formed by the through groove 409 and the elastic sheet 410, that is, at this time, under the action of the elastic sheet 410 blocking the limiting sleeve 407, the limiting sleeve 407 will rotate around the fixed shaft 404 until the other end of the limiting sleeve 407 is tightly fitted with the bottom of the inner wall of the guide groove 408, and at this time, the limiting sleeve 407 no longer hinders the rotating tooth 405 from moving toward the driving gear 4 02, the rotating teeth 405 are restricted from rotating toward the end opposite to the rotation direction of the driving gear 402, that is, when the driving gear 402 continues to rotate, the rotating teeth 405 will rotate around the fixed shaft 404 toward the end of the driving gear 402, so that the driving gear 402 can no longer drive the rotating baffle 209 to rotate by cooperating with the fixed shaft 404 through the rotating teeth 405. At this time, the through holes 211 in the middle of the fixed baffle 208 and the rotating baffle 209 completely overlap or completely intersect with each other; On the contrary, when the driving gear 402 rotates in the reverse direction, the limiting sleeve 407 no longer prevents the rotating tooth 405 from rotating in the direction of rotation of the driving gear 402, but restricts the rotating tooth 405 from rotating in the opposite direction of rotation of the driving gear 402. That is, when the driving gear 402 continues to rotate, that is, when the driving gear 402 rotates in the reverse direction, the limiting sleeve 407 will prevent the rotating tooth 405 from rotating in the direction of rotation of the driving gear 402, which will cause the driving gear 402 to drive the rotating baffle 209 to rotate in the reverse direction through the fixed shaft 404. In this process, the limiting sleeve 407 will squeeze the elastic sheet 410 and will not be affected by the elastic sheet 410. The gap between the elastic sheet 410 and the through groove 409 is affected until the limiting sleeve 407 moves to another position of the elastic sheet 410 inclined toward the blocking movement of the limiting sleeve 407, which will cause the limiting sleeve 407 to rotate, so that the driving gear 402 can no longer drive the rotating baffle 209 to rotate. At this time, the through holes 211 in the middle of the fixed baffle 208 and the rotating baffle 209 are completely staggered or completely overlapped with each other, so that no additional driving source is required, and the closing and connection of the second discharge pipe 203 are synchronously carried out with the change of the rotation direction of the first drive shaft 102, thereby achieving the purpose of self-sealing during stirring and achieving connection during pouring; By providing the torsion spring 406 , the rotating teeth 405 will always fit the bottom of the driving gear 402 , so as to meet the need of driving the rotating baffle 209 to rotate by cooperating with the fixed shaft 404 when the driving gear 402 rotates forward and reversely.
