The diameter of the air outlet check valve is smaller than the diameter of the air inlet check valve. The sliding telescopic rod A and the sliding telescopic rod B are circular rod structures, and the cross-section of the connecting block is square.

[0014] Preferably, the outer wall of the counterweight ball is provided with an acceleration mechanism, and the acceleration mechanism includes a hinge block A, one end of which is fixedly connected to the outer wall of the counterweight ball, the inner wall of the hinge block A is hinged with a hinged toggle rod, the other end of the hinged toggle rod is hinged with a hinge block B, and the outer wall of the hinge block B is fixedly connected with a connecting sleeve.

[0015] Preferably, the inner wall of the connecting sleeve is rotatably connected to a transverse sliding sleeve, and the inner wall of the transverse sliding sleeve is slidably connected to the outer wall of the rotating rod.

[0016] Preferably, the outer wall of the rotating rod is fixedly connected to a limit fixing sleeve, and two sides of the limit fixing sleeve are in contact with one side of the transverse sliding sleeve.

[0017] The present invention provides a chute device for pouring concrete retaining walls in construction engineering. It has the following beneficial effects:

[0018] 1. The present invention sets a speed limiting mechanism. When the fluid is slowed down, the flow rate is faster when the slope is higher or the fluid is thinner. At this time, the motor can be started to control the rotation of the rotating rod, and the rotation of the rotating rod drives the bottom arc-shaped speed limiting plate to rotate by ten to forty-five degrees, so that the raised arc-shaped speed limiting plate can be used to intercept and collide with the fluid. Through different degrees of viscosity and different slopes, the lifting angle of the arc-shaped speed limiting plate can be adjusted in real time according to the situation, so as to achieve a more appropriate speed limiting effect under different circumstances, and the speed limit can be changed without changing the angle of the chute plate itself, so as to avoid the splashing of the fluid in the chute plate by changing the angle of the chute plate;

[0019] 2. The present invention sets a speed limiting mechanism. When the cement concrete on the chute plate slides down in the chute plate due to gravity, the speed-reducing groove inside the chute plate, the connecting block, the sliding telescopic rod A, the sliding telescopic rod B and the counterweight ball on the arc-shaped speed limiting plate are used to limit the speed of the concrete and cement falling inside. In the construction of a high retaining wall, the speed of the lower fluid is effectively limited. Without extending the chute plate, the deceleration effect can also be achieved for fluids such as concrete and cement.

[0020] 2. The present invention sets a speed limiting mechanism. Once the problem of slow flow rate in the chute plate caused by cement concrete with high viscosity occurs, the motor can be started to control the rotating rod to rotate 180 degrees based on the original position, so that the rotating rod rotates to drive the arc-shaped speed limiting plate to be completely lifted, and the channel inside the chute plate is completely opened, so as to achieve the acceleration effect of the fluid in the steeper chute plate based on the original state of the arc-shaped speed limiting plate at the bottom, thereby achieving different degrees of deceleration according to different situations, and accelerating the output of the fluid. Compared with the original chute plate with a large slope to transmit the fluid, the problem that the chute plate with a large slope encounters a slow flow rate of concrete with a large viscosity and cannot be solved is avoided;

[0021] 3. The present invention sets a speed limiting mechanism. If the concrete with higher viscosity flows down, even if the arc-shaped speed limiting plate is completely lifted up, the fluid still flows slowly due to its own weight. At this time, the motor is started to control the rotating rod and the arc-shaped speed limiting plate to rotate continuously and slowly, and the rotating rod drives the arc-shaped speed limiting plate to rotate in the direction of moving the fluid in the chute plate downward, thereby actively accelerating the downward transportation effect of the fluid by moving the fluid.

[0022] 4. The present invention provides a speed limiting mechanism, so that when the sliding telescopic rod A and the sliding telescopic rod B retract into the connecting block, the air is discharged very slowly through the air outlet non-return valve, so that when the rotating rod drives the arc speed limiting plate to rotate continuously, even if the arc speed limiting plate rotates to the bottom of the rotating rod, it will be lifted up again by the rotating rod before the sliding telescopic rod A and the sliding telescopic rod B retract into the inside of the connecting block, and the sliding telescopic rod A and the sliding telescopic rod B after going up will quickly fall into the inside of the connecting block, and the air will be quickly discharged through the large-diameter air intake non-return valve, so that when the rotating rod continuously drives the arc speed limiting plate to rotate, the sliding telescopic rod A and the sliding telescopic rod B can be fully kept in the extended state, thereby increasing the contact area of ​​the viscous fluid in the chute plate below, thereby improving the pushing effect on the fluid, and the rotating rod and the arc speed limiting plate will not extend out when the rotating rod and the arc speed limiting plate are stationary in the chute plate, thereby avoiding the problem of blocking the fluid in a stationary state.

[0023] 5. The present invention sets an acceleration mechanism. When the arc speed limit plate is above the rotating rod, the sliding telescopic rod A, the sliding telescopic rod B and the counterweight ball are released from the inside of the connecting block, the hinged block A, the hinged toggle rod and the hinged block B are pushed to the connecting sleeve to drive the transverse sliding sleeve to slide horizontally left and right on the outer wall of the rotating rod. When the connecting sleeve and the transverse sliding sleeve slide horizontally on the outer wall of the rotating rod, the two hinged toggle rods that were originally in a vertical state are changed into a V shape, so that when the rotating rod drives the arc speed limit plate to rotate and toggle the concrete to accelerate the flow, the hinged toggle rod can be expanded to further increase the contact area above the concrete fluid. In addition, by sliding the transverse sliding sleeve on the outer wall of the rotating rod, the problem of concrete falling on the rotating rod and adhering to it can be prevented during the rotation and toggle.

[0024] 6. The present invention sets an acceleration mechanism, and the air outlet one-way valve can only let out air but not let in air, while the air inlet one-way valve can only let in air but not let out air, thereby realizing one-way circulation of air, which is continuously drawn into the interior of the connecting block from the air inlet one-way valve, and then squeezed through the interior of the connecting block to be discharged through the air outlet one-way valve, thereby realizing the reciprocating telescopic work of the sliding telescopic rod A and the sliding telescopic rod B, and by having different calibers, the reciprocating telescopic speeds of the sliding telescopic rod A and the sliding telescopic rod B are different, the mutual stretching speed of the sliding telescopic rod A and the sliding telescopic rod B is faster, and the recovery speed is slower, thereby automatically controlling the lifting and sliding speeds of the sliding telescopic rod A and the sliding telescopic rod B.

DETAILED DESCRIPTION

[0041] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a chute device for pouring concrete retaining walls in construction engineering, comprising a chute plate 2, a connecting rod 1 is fixedly connected to the outer wall of the chute plate 2, a motor 5 is fixedly connected to one end of the connecting rod 1, a reinforcing plate 8 is fixedly connected to the bottom of the chute plate 2, and a speed limiting mechanism 3 is arranged inside the chute plate 2;

[0042] The speed limiting mechanism 3 comprises:

[0043] The deceleration groove 301 is an arc-shaped structure. The deceleration groove 301 is opened on the inner wall of the chute plate 2. The output end of the motor 5 is fixedly connected to a rotating rod 302. The outer wall of the rotating rod 302 is fixedly connected to a gear 6. The outer wall of the gear 6 is provided with a chain 7. The outer wall of the rotating rod 302 is rotatably connected to the inner wall of the chute plate 2. The outer wall of the rotating rod 302 is fixedly connected to an arc-shaped speed limiting plate 303. The deceleration groove 301 is used to slow down the fluid;

[0044] The connecting block 304 is fixedly connected to the inner wall of the chute plate 2, the inner wall of the connecting block 304 is slidably connected to a sliding telescopic rod A305, the inner wall of the sliding telescopic rod A305 is slidably connected to a sliding telescopic rod B306, and one end of the sliding telescopic rod B306 is fixedly connected to a counterweight ball 307;

[0045] When in use, when the cement concrete on the chute plate 2 slides down in the chute plate 2 due to gravity, the speed-reducing groove 301 inside the chute plate 2, and the connecting block 304, the sliding telescopic rod A305, the sliding telescopic rod B306 and the counterweight ball 307 on the arc-shaped speed-limiting plate 303 are used to limit the speed of the concrete and cement falling inside, thereby effectively limiting the speed of the lower fluid in the construction of a high retaining wall, and achieving a deceleration effect on fluids such as concrete and cement without extending the chute plate 2;

[0046] Example 2: Please refer to Figure 1-9On the basis of the first embodiment, the present invention provides a technical solution: the inner wall of the connecting block 304 is connected to the inner wall of the sliding telescopic rod A305, the inner wall of the sliding telescopic rod A305 is connected to the inner wall of the sliding telescopic rod B306, the inner wall of the connecting block 304 is connected to the inner wall of the arc speed limit plate 303, and the inner wall of the arc speed limit plate 303 is connected to the inner wall of the rotating rod 302.

[0047] A square groove 308 is formed on the outer wall of the rotating rod 302 , and an air intake check valve 309 is fixedly connected to the inner wall of the square groove 308 .

[0048] One end of the rotating rod 302 is fixedly connected to a connecting ring 310 , an inner wall of the connecting ring 310 is provided with a circular hole 311 , and an inner wall of the circular hole 311 is fixedly connected to a gas outlet one-way valve 312 .

[0049] The inner wall of the inlet check valve 309 is connected to the inner wall of the rotating rod 302, and the inner wall of the outlet check valve 312 is connected to the inner wall of the rotating rod 302. The diameter of the outlet check valve 312 is smaller than that of the inlet check valve 309. The sliding telescopic rod A305 and the sliding telescopic rod B306 are circular rod structures, and the cross section of the connecting block 304 is square.

[0050] While slowing down the fluid, when the slope is higher or the fluid is thinner, the flow rate is faster. In this case, the motor 5 can be started to control the rotation of the rotating rod 302, and the rotation of the rotating rod 302 can be used to drive the bottom arc-shaped speed limit plate 303 to rotate by ten to forty-five degrees, so that the raised arc-shaped speed limit plate 303 can be used to intercept and collide with the fluid. Through different degrees of viscosity and different slopes, the lifting angle of the arc-shaped speed limit plate 303 can be adjusted in real time according to the situation, so as to achieve a more suitable speed limit effect under different situations;

[0051] The gear 6 is driven to rotate by the motor 5, which drives a large number of gears 6 through the chain 7. Each gear 6 corresponds to a speed limiting mechanism 3 and an acceleration mechanism 4 to work.

[0052] Once the problem of slow flow rate in the chute plate 2 caused by high viscosity cement concrete occurs, the motor 5 can be started to control the rotating rod 302 to rotate 180 degrees based on the original position, so that the rotating rod 302 rotates to drive the arc-shaped speed limit plate 303 to be completely lifted, and the channel inside the chute plate 2 is completely opened, so as to achieve the acceleration effect of the fluid in the steeper chute plate 2 based on the original state of the arc-shaped speed limit plate 303 being at the bottom, thereby achieving different degrees of deceleration according to different situations, and accelerating the output of the fluid. Compared with the original chute plate 2 with a larger slope to transmit the fluid, the problem that the chute plate 2 with a larger slope encounters a slow flow rate of concrete with a larger viscosity and cannot be solved is avoided;

[0053] If the concrete with higher viscosity flows down, even if the arc-shaped speed limiting plate 303 is completely lifted up, the fluid still flows slowly due to its own weight. At this time, the motor 5 is started to control the rotating rod 302 and the arc-shaped speed limiting plate 303 to rotate continuously and slowly, and the rotating rod 302 drives the arc-shaped speed limiting plate 303 to rotate in the direction of moving the fluid in the chute plate 2 downward, thereby actively accelerating the downward transportation of the fluid by moving the fluid.

[0054] When the rotating rod 302 drives the arc-shaped speed limiting plate 303 to rotate and move the fluid continuously and slowly, when the arc-shaped speed limiting plate 303 slowly rises to above the rotating rod 302, the sliding telescopic rod A305 and the sliding telescopic rod B306 in the connecting block 304 on the arc-shaped speed limiting plate 303 are pulled out of the connecting block 304 to be extended and lengthened as the gravity of the counterweight ball 307 decreases. When the sliding telescopic rod A305 and the sliding telescopic rod B306 lengthen, the air in the connecting block 304 is sucked into the sliding telescopic rod A305 and the sliding telescopic rod B306, and the connecting block 304 The internal air is connected with the arc-shaped speed limiting plate 303 and the rotating rod 302, and is drawn into the connecting block 304 through the air inlet check valve 309 on the outer wall of the rotating rod 302. When the arc-shaped speed limiting plate 303 is located below the rotating rod 302, the sliding telescopic rod A305 and the sliding telescopic rod B306 will be pressed down by the gravity of the counterweight ball 307 to press the sliding telescopic rod A305 and the sliding telescopic rod B306 back into the connecting block 304, and the air in the connecting block 304 is connected with the air outlet check valve 312 through the arc-shaped speed limiting plate 303 and the rotating rod 302 again, and is ejected through the air outlet check valve 312. The air flow of the one-way valve 312 and the one-way valve 309 is one-way, so that the air will not flow back, and the diameter of the one-way valve 312 is much smaller than that of the one-way valve 309. Therefore, when the sliding telescopic rod A305 and the sliding telescopic rod B306 are retracted to the connecting block 304, the air is discharged very slowly through the one-way valve 312. Therefore, when the rotating rod 302 drives the arc speed limit plate 303 to rotate continuously, even if the arc speed limit plate 303 rotates to the bottom of the rotating rod 302, it will be lifted up again by the rotating rod 302 before the sliding telescopic rod A305 and the sliding telescopic rod B306 are retracted to the inside of the connecting block 304. Afterwards, the sliding telescopic rod A305 and the sliding telescopic rod B306 will quickly fall inside the connecting block 304, and the air will be quickly discharged through the large-diameter air intake check valve 309, so that when the rotating rod 302 continuously drives the arc-shaped speed limiting plate 303 to rotate, the sliding telescopic rod A305 and the sliding telescopic rod B306 can be fully extended, thereby increasing the contact area of ​​the viscous fluid in the chute plate 2 below to intercept and move, thereby improving the pushing effect on the fluid, and the rotating rod 302 and the arc-shaped speed limiting plate 303 will not extend out when they are stationary in the chute plate 2, avoiding the problem of blocking the fluid in a stationary state;

[0055] In addition, the air outlet check valve 312 can only discharge air but not intake air, while the air intake check valve 309 can only intake air but not discharge air, thereby realizing one-way circulation of air. Air is continuously drawn into the interior of the connecting block 304 from the air intake check valve 309, and then squeezed through the interior of the connecting block 304 to be discharged through the air outlet check valve 312, thereby realizing the reciprocating telescopic work of the sliding telescopic rod A305 and the sliding telescopic rod B306. In addition, due to the different calibers of 312 and 309, the reciprocating telescopic speeds of the sliding telescopic rod A305 and the sliding telescopic rod B306 are different. The mutual stretching speed of the sliding telescopic rod A305 and the sliding telescopic rod B306 is faster, while the recovery speed is slower, thereby automatically controlling the lifting and sliding speeds of the sliding telescopic rod A305 and the sliding telescopic rod B306.

[0056] Example 3: Please refer to Figure 1-15 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an acceleration mechanism 4 is arranged on the outer wall of the counterweight ball 307, and the acceleration mechanism 4 comprises a hinge block A401, one end of the hinge block A401 is fixedly connected to the outer wall of the counterweight ball 307, an hinged toggle rod 402 is hinged on the inner wall of the hinge block A401, and the other end of the hinged toggle rod 402 is hinged on the hinge block B403, and the outer wall of the hinge block B403 is fixedly connected to a connecting sleeve 404.

[0057] The inner wall of the connecting sleeve 404 is rotatably connected with a transverse sliding sleeve 405 , and the inner wall of the transverse sliding sleeve 405 is slidably connected with the outer wall of the rotating rod 302 .

[0058] The outer wall of the rotating rod 302 is fixedly connected to a limited position fixing sleeve 406, and two sides of the limited position fixing sleeve 406 are in contact with one side of the horizontal sliding sleeve 405;

[0059] When the arc speed limit plate 303 is above the rotating rod 302, the sliding telescopic rod A305, the sliding telescopic rod B306 and the counterweight ball 307 are released from the connecting block 304, and the hinge block A401, the hinged toggle rod 402 and the hinged block B403 are pushed to the connecting sleeve 404 to drive the transverse sliding sleeve 405 to slide horizontally left and right on the outer wall of the rotating rod 302. When the connecting sleeve 404 and the transverse sliding sleeve 405 slide horizontally on the outer wall of the rotating rod 302, the two hinged toggle rods 402, which were originally in a vertical state, are changed into a V shape, so that when the rotating rod 302 drives the arc speed limit plate 303 to rotate and toggle the concrete to accelerate the flow, the hinged toggle rod 402 can be expanded to further increase the contact area with the top of the concrete fluid, and the transverse sliding sleeve 405 slides on the outer wall of the rotating rod 302, so as to prevent the concrete from falling on the rotating rod 302 when rotating and toggling.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
