Description

Technical Field

[0001] This invention belongs to the field of concrete placement, specifically relating to a concrete production and placement device for a concrete pump used in sponge cities. Background Technology

[0002] Sponge cities are an ecological construction method for dealing with rainwater. By absorbing and storing rainwater on-site, cities can be made to respond to rainwater as flexibly as a sponge. The concrete pump's concrete production and placement device is a special equipment for green space construction in sponge cities. The concrete pump truck transports concrete from the mixing plant to the pouring point, and then the placement device precisely spreads it on the green space.

[0003] Patent CN222162016U discloses a concrete production placing mechanism for a concrete pump, including a mounting base installed on the side surface of a concrete pump truck. A hydraulic cylinder is fixedly connected to the inner bottom surface of the mounting base, and a lifting frame is fixedly connected to the output end of the hydraulic cylinder. A placing frame is fixedly connected to one side surface of the lifting frame, and a fixing seat is fixedly connected to the upper surface of the placing frame. An arc-shaped fixing plate is embedded and connected to the other side surface of the fixing seat. In this invention, the output end of the hydraulic cylinder can drive the lifting frame to move up or down. The limiting groove and the limiting rod limit the lifting of the lifting frame, making the height of the placing frame adjustable. Furthermore, it can place concrete into flower bed molds with different thickness requirements. Rollers No. 1 and No. 2 are used for spreading operations, making the concrete placement more uniform. The placing frame prevents concrete splashing and protects the stepper motor.

[0004] When the concrete production and placement device is used to place concrete in the green space of the sponge city, the concrete slurry delivered by the concrete pump truck falls directly onto the green space, causing the concrete slurry to clump together and accumulate. This leads to uneven distribution of the concrete by the concrete production and placement device. At the same time, the excessively fast rotation of the round rod can easily lead to poor material spreading effect of the orifice plate, and the concrete slurry adheres to the surface of the orifice plate, resulting in poor material discharge effect of the orifice plate. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The present invention uses a housing, a pressing assembly, a connecting block, a roller assembly, a strip plate, a shovel plate, a Z-shaped plate, a motor, a round rod, and a transmission assembly to cooperate with a perforated plate. The pressure roller of the transmission assembly II presses the concrete slurry on the green area to flatten it during the reverse process. The transmission assembly I drives the round rod to rotate forward. The round rod rotates forward in the Z-shaped plate. The round rod drives the perforated plate to rotate forward. The concrete slurry falls onto the surface of the perforated plate. During the rotation of the perforated plate, the concrete slurry is evenly spread onto the shovel plate, so that the shovel plate evenly distributes the concrete slurry on the green area, preventing the concrete slurry from accumulating in clumps and causing uneven distribution of the concrete production material distribution device.

[0018] (2) By setting a speed limiting device, the present invention enables the I-shaped plate, rubber ring, slide rod and return frame to work with the spring. The perforated plate drives the I-shaped plate to rotate forward, and the I-shaped plate drives the rubber ring to rotate forward. When the rubber ring rotates, the return frame slides to the left on the slide rod. The return frame presses against the surface of the rubber ring by the elastic force of the spring, so that the round rod rotates slowly, preventing the round rod from rotating too fast and causing poor material spreading effect of the perforated plate.

[0019] (3) By setting a speed limiting device, the present invention enables the short column and the slide plate to cooperate with the groove plate. The circular frame drives the short column to move to the left, and the short column drives the slide plate to move to the left. The slide plate moves to the left in the groove plate, and the groove plate supports the movement of the slide plate, preventing the slide rod from being deformed and damaged due to the sliding of the circular frame.

[0020] (4) The present invention uses a vibration device to make the connecting plate, long rod and strip rod cooperate with the rubber column. The I-shaped disk drives the connecting plate to rotate forward. Under the action of gravity, the long rod rotates to the left in the connecting plate. The long rod drives the strip rod to rotate to the left. The strip rod drives the rubber column to rotate to the left. During the left rotation, the rubber column hits the surface of the orifice plate to prevent concrete slurry from adhering to the surface of the orifice plate and causing poor material discharge effect.

[0021] (5) The present invention uses a vibration device to make the short column 2 and the double arc plate cooperate with the ring plate. The connecting plate drives the short column 2 to rotate in the forward direction, the short column 2 drives the double arc plate to rotate in the forward direction, the double arc plate drives the ring plate to rotate in the forward direction, and the ring plate blocks the concrete slurry from splashing, so as to prevent the concrete slurry from splashing and causing the placement effect of the material placement device to be unqualified.

[0031] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0032] like Figure 1-7 As shown, one embodiment of the present invention is: a concrete production and placement device for a concrete pump used in sponge cities, comprising: a housing 1, a concrete inlet on the top surface of the housing 1, a pressing component 2 on the right side of the top surface of the housing 1, the pressing component 2 comprising: a U-shaped frame 201, a second motor 202, two pressure rollers 203 and a second transmission component 204, the U-shaped frame 201 being welded to the top surface of the housing 1, the second motor 202 being fixed to the top surface of the U-shaped frame 201, the two pressure rollers 203 being installed through and rotatably on the inner wall of the U-shaped frame 201, the second transmission component 204 being disposed on the front side of the output shaft of the second motor 202 and the rotating shaft of the two pressure rollers 203, and a connecting block 3 being disposed on the left side of the top surface of the housing 1; Roller assembly 4 is located on the left side of housing 1; Strip 5 is fixed inside the top of the casing 1, and strip 5 is located to the right of the concrete pouring port of the casing 1. The shovel plate 6 is fixed to the bottom surface of the strip plate 5 and is located to the right of the concrete pouring port of the casing 1. Z-shaped plate 7, Z-shaped plate 7 is fixed inside the top of the casing 1; Motor 8 is fixed to the left side of Z-shaped plate 7; The round rod 9 is installed through and rotatably on the inner wall of the Z-shaped plate 7 at the front and rear. The round rod 9 is located below the concrete pouring port of the casing 1. Transmission assembly 10 is located on the front of the output shaft of motor 8 and the front of the round rod 9. Several orifice plates 11 are fixed to the outer wall of the round rod 9. The several orifice plates 11 are used to distribute the concrete output by the concrete pump truck.

[0033] Roller assembly 1 4 includes: a slant frame, a drive shaft, and two tires. The slant frame is fixed to the housing 1. The drive shaft passes through and is rotatably mounted on the inner wall of the slant frame. The two tires are fixed to the front and back of the drive shaft. Transmission assembly 1 10 and transmission assembly 2 204 are equipped with belts and transmission rollers. The belts are rotatably mounted on the inner wall of the transmission rollers. The outer surface of the drive structure needs to be equipped with a dust cover to prevent dust from affecting the belt transmission effect. The transmission roller is used to drive the round rod 9 and the pressure roller 203. The shovel plate 6 is located on the left side of the pressing assembly 2. The bottom of the shovel plate 6 is provided with several shovel teeth. The shovel plate 6 is inclined and set below each perforated plate 11. When using this concrete production and placement device to place concrete in green spaces in sponge cities, the operator installs the connecting block 3 at the rear of the concrete pump truck, inserts the input pipe of the concrete pump truck into the concrete pouring port of the casing 1, and the concrete pump truck moves to the left. The concrete pump truck drives the connecting block 3 to move to the left, the connecting block 3 drives the casing 1 to move to the left, the casing 1 drives the roller assembly 4 to move to the left, the tires of the roller assembly 4 roll to the left, the casing 1 drives the strip 5 to move to the left, the strip 5 drives the shovel 6 to move to the left, the concrete pump truck uses the input pipe to transport concrete slurry, and the shovel 6 spreads the concrete slurry on the green space. At the same time, the operator starts the pressing assembly 2, the output shaft of motor 202 starts to reverse, the output shaft of motor 202 drives the transmission roller of transmission assembly 204 to reverse, the transmission roller drives the belt to reverse, the belt drives the other two transmission rollers to reverse, and transmission assembly 204 drives... The pressure roller 203 reverses direction within the U-shaped frame 201. During this reversal, the pressure roller 203 smooths the concrete slurry on the green area. Simultaneously, while the concrete slurry is being delivered through the input pipe, the operator starts motor 8. The output shaft of motor 8 rotates forward, driving the transmission roller of transmission assembly 10 to rotate forward. This transmission roller drives the belt to rotate forward, which in turn drives another transmission roller to rotate forward. Transmission assembly 10 then drives the round rod 9 to rotate forward. The round rod 9 rotates forward within the Z-shaped plate 7, which in turn drives the perforated plate 11 to rotate forward. The concrete slurry falls onto the surface of the perforated plate 11. As the perforated plate 11 rotates, it evenly spreads the concrete slurry onto the shovel plate 6, ensuring that the shovel plate 6 distributes the concrete slurry evenly across the green area. This prevents the concrete slurry from clumping together and causing uneven distribution during concrete distribution.

[0034] A speed limiting device 12 is provided on the outer wall of the round rod 9. The speed limiting device 12 is used to slow down the speed at which the concrete is distributed by the orifice plate 11. A vibration device 13 is provided on the side of the speed limiting devices 12 that are close to each other. The vibration device 13 is used to strike the orifice plate 11 to reduce the amount of concrete adhering to the surface of the orifice plate 11.

[0035] Working principle: Connecting block 3 is installed at the rear of the concrete pump truck. The input pipe of the concrete pump truck is inserted into the concrete pouring port of the casing 1. When the concrete pump truck moves to the left, it drives connecting block 3 to move to the left. Connecting block 3 drives casing 1 to move to the left, which in turn drives roller assembly 4 to move to the left. The tires of roller assembly 4 roll to the left, which in turn drives strip 5 to move to the left. Strip 5 then drives shovel 6 to move to the left. The concrete pump truck uses the input pipe to deliver concrete slurry, and shovel 6 spreads the concrete slurry onto the ground. The output shaft of the dynamic pressing assembly 2 and the motor 202 drive the transmission assembly 204 to reverse, which in turn drives the pressure roller 203 to reverse. During the reverse rotation, the pressure roller 203 presses the concrete slurry on the green area to flatten it. The output shaft of the motor 8 drives the transmission assembly 10 to rotate forward, which in turn drives the round rod 9 to rotate forward. The round rod 9 rotates forward in the Z-shaped plate 7, which in turn drives the perforated plate 11 to rotate forward. The concrete slurry falls onto the surface of the perforated plate 11, and during the rotation, the perforated plate 11 spreads the concrete slurry evenly onto the shovel plate 6.

[0036] like Figure 1-7 As shown, based on the above embodiments, in another embodiment of the present invention, the speed limiting device 12 includes: two I-shaped discs 121, which are fixed to the outer wall of the round rod 9; Rubber rings 122 are fixed to the inner walls of the two I-shaped disks 121 respectively; Two sliding rods 123 are fixed to the right side of the Z-shaped plate 7; The spiral frame 124 is slidably mounted on the outer wall of the two slide rods 123 respectively; Spring 125 is fixed between the left side of the two hinge frames 124 and the outer wall of the two slide rods 123 respectively, and spring 125 is sleeved on the outside of the two slide rods 123 respectively; The ring 124 is pressed against the surface of the rubber ring 122 by the spring 125 to slow down the rotation speed of the round rod 9; While the round rod 9 drives the perforated plate 11 to rotate clockwise, the perforated plate 11 drives the I-shaped disk 121 to rotate clockwise, and the I-shaped disk 121 drives the rubber ring 122 to rotate clockwise. The Z-shaped plate 7 supports the sliding rod 123, and the sliding rod 123 supports the return frame 124. When the rubber ring 122 rotates, the return frame 124 slides to the left on the sliding rod 123. The return frame 124 presses against the surface of the rubber ring 122 through the elastic force of the spring 125, slowing down the rotation speed of the rubber ring 122 and allowing the round rod 9 to rotate slowly. This avoids the problem of poor material spreading effect of the perforated plate 11 caused by the round rod 9 rotating too fast when the concrete spreading device is spreading concrete in the green area.

[0037] A short column 126 is fixed to the top surface of each of the two Z-shaped frames 124, and a sliding plate 127 is fixed to the top surface of each of the two short columns 126. Two grooved plates 128 are fixed to the right side of the Z-shaped plate 7, and the outer walls of the two sliding plates 127 are slidably connected to the inner walls of the two grooved plates 128. As the sliding frame 124 slides to the left on the slide bar 123, the sliding frame 124 drives the short column 126 to move to the left, and the short column 126 drives the sliding plate 127 to move to the left. The sliding plate 127 moves to the left in the grooved plate 128, and the grooved plate 128 supports the movement of the sliding plate 127. This ensures that the slide bar 123 will not deform or be damaged when the sliding frame 124 slides to the left on the slide bar 123, thus avoiding the problem of deformation and damage to the slide bar 123 caused by the sliding of the sliding frame 124 when the concrete placing device is used for concrete placement in the green area.

[0038] The vibration device 13 includes: a plurality of connecting plates 131, which are respectively fixed on one side of the two I-shaped disks 121 that are close to each other; Long rods 132 are rotatably installed on the side of each connecting plate 131 that is close to each other, and long rods 132 are located between each perforated plate 11. Bars 133 are fixed in pairs to the outer wall of each long bar 132; Rubber posts 134 are fixed between each bar 133 and each long bar 132. The outer wall of each perforated plate 11 is on the movement trajectory of each rubber column 134, which is used to strike the surface of the perforated plate 11. While the I-shaped disc 121 drives the rubber ring 122 to rotate clockwise, the I-shaped disc 121 drives the connecting plate 131 to rotate clockwise, the connecting plate 131 drives the long rod 132 to rotate clockwise, the long rod 132 drives the bar rod 133 to rotate clockwise, and the bar rod 133 drives the rubber column 134 to rotate clockwise. Under the action of gravity, the long rod 132 rotates to the left in the connecting plate 131, the long rod 132 drives the bar rod 133 to rotate to the left, and the bar rod 133 drives the rubber column 134 to rotate to the left. During the leftward rotation, the rubber column 134 strikes the surface of the orifice plate 11, thereby avoiding the problem of poor material discharge effect of the orifice plate 11 when the concrete placing device is used for concrete placing in green areas due to the concrete slurry adhering to the surface of the orifice plate 11.

[0039] Several connecting plates 131 are fixed with short columns 135 on their sides that are close to each other. Each short column 135 is fixed with a double arc plate 136 at the end away from each connecting plate 131. Two ring plates 137 are fixed on the outer wall of the double arc plate 136. The two ring plates 137 are located on the side close to the two I-shaped plates 121 that are close to each other. While the connecting plate 131 drives the long rod 132 to rotate clockwise, the connecting plate 131 also drives the short column 135 to rotate clockwise. The short column 135 drives the double arc plate 136 to rotate clockwise, and the double arc plate 136 drives the ring plate 137 to rotate clockwise. During the rotation, the ring plate 137 blocks the splashing of concrete slurry, thereby avoiding the problem of unqualified placement effect of the concrete placing device caused by the splashing of concrete slurry when the concrete placing device is placed in the green space.

[0040] Working principle: The perforated plate 11 drives the I-shaped plate 121 to rotate clockwise, the I-shaped plate 121 drives the rubber ring 122 to rotate clockwise, the slide rod 123 supports the return frame 124, when the rubber ring 122 rotates, the return frame 124 slides to the left on the slide rod 123, and the return frame 124 presses against the surface of the rubber ring 122 by the elastic force of the spring 125; The circular frame 124 drives the short column 126 to move to the left, the short column 126 drives the slide plate 127 to move to the left, the slide plate 127 moves to the left in the groove plate 128, and the groove plate 128 supports the movement of the slide plate 127. The I-shaped disk 121 drives the connecting plate 131 to rotate clockwise. Under the action of gravity, the long rod 132 rotates to the left in the connecting plate 131. The long rod 132 drives the bar 133 to rotate to the left. The bar 133 drives the rubber column 134 to rotate to the left. During the leftward rotation, the rubber column 134 strikes the surface of the perforated plate 11. Connecting plate 131 drives short column 2 135 to rotate forward, short column 2 135 drives double arc plate 136 to rotate forward, double arc plate 136 drives ring plate 137 to rotate forward, and ring plate 137 blocks concrete slurry splashing.
