Description

Technical Field

[0001] The invention relates to the technical field of floor construction devices, and in particular to a special concrete pouring and initial leveling device for floors. Background Art

[0002] In floor construction, concrete is first poured evenly on the ground and then the initial leveling construction can be carried out. Initial leveling construction generally uses a scraper to scrape the concrete flat, thereby forming a highly flat floor. In order to ensure that the concrete in each place is the same, more concrete is generally poured. The scraper pushes away the excess concrete as it passes, and at the same time scrapes the remaining concrete flat. However, since concrete itself has a certain viscosity, the excess concrete will be pulled forward during the scraping process, which makes it easy for the ground to form uneven textures under the pulling, affecting the quality of the floor. Summary of the invention

[0003] The purpose of the present invention is to provide a special concrete pouring and initial leveling device for floor, which can smooth the concrete surface while pushing excess concrete, thereby improving the quality of the floor surface.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] A special concrete pouring and initial leveling device for floor, comprising an initial leveling head; the initial leveling head comprises a driving mechanism, a flattening roller, a transmission roller and a conveyor belt; the transmission belt is sleeved on the flattening roller and the transmission roller, so that the flattening roller and the transmission roller rotate synchronously under the drive of the transmission belt; the driving mechanism is transmission-connected to the flattening roller or the transmission roller; the line connecting the flattening roller and the transmission roller is inclined to the ground and the transmission roller is located above the flattening roller.

[0006] Furthermore, the initial flattening head also includes a smoothing roller; the conveyor belt is also connected to the smoothing roller; and the conveyor belt is parallel to the ground when passing between the flattening roller and the smoothing roller.

[0007] Furthermore, the initial flattening head also includes a connecting frame; the flattening roller, transmission roller and smoothing roller are all connected to the connecting frame; the connecting frame is hinged on the base and the rotating shaft of the connecting frame is concentric with the rotating shaft of the flattening roller; the connecting frame is also provided with a swinging mechanism for driving it to swing, so that the transmission belt between the smoothing roller and the flattening roller swings to be parallel to the ground or inclined to the ground, and when inclined to the ground, the distance between the smoothing roller and the ground is greater than the distance between the flattening roller and the ground.

[0008] Furthermore, the initial flattening head also includes a brush; the brush is arranged in cooperation with the driving roller so that when the conveyor belt between the smoothing roller and the flattening roller is parallel to the ground, the brush abuts against the surface of the conveyor belt.

[0009] Furthermore, the initial flattening head also includes a plurality of nozzles; the plurality of nozzles are distributed along the length direction of the driving roller and the nozzles point to the end of the brush.

[0010] Furthermore, it also includes a moving part; the initial flattening head is arranged on the moving part in a liftable manner; the moving part is also provided with a lifting mechanism for driving the initial flattening head to rise and fall.

[0011] Furthermore, the initial flat head is also provided with a laser ranging sensor; the laser ranging sensor is vertically pointed to the ground.

[0012] Furthermore, the swing mechanism includes an eccentric wheel and a connecting rod; two ends of the connecting rod are hinged to the connecting frame and the eccentric wheel respectively.

[0013] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0014] When the floor-specific concrete pouring and initial leveling device of the present invention is used, the initial leveling head contacts the concrete surface downward. Driven by an external mechanism, the initial leveling head gradually moves forward along the concrete surface. At this time, the flattening roller presses the concrete surface through the conveyor belt sleeved on its outside, so that the excess concrete is pushed forward during the movement of the conveyor belt, and the conveyor belt also scrapes the ground flat. In order to better smooth the concrete surface, the driving mechanism also drives the flattening roller or the transmission roller to rotate, so that the conveyor belt moves. The conveyor belt fits the concrete surface and moves to smooth the concrete surface. In order to achieve the smoothing of the concrete by the conveyor belt, the conveyor belt must move relative to the concrete surface. Therefore, the smoothing effect can be controlled by controlling the rotation speed of the driving mechanism.

[0015] In addition, the flattening roller and the driving roller tension the conveyor belt, so that the tensioned conveyor belt is in a plate shape, which can better push the excess concrete forward. The moving direction of the conveyor belt can also be the same as the pushing direction of the concrete, so that the excess concrete is pushed forward by the movement of the initial flattening head and the pushing of the conveyor belt, which is better than the prior art that only pushes forward by the scraper.

[0016] The additional smoothing roller allows the tensioned conveyor belt between the smoothing roller and the flattening roller to have a larger area in contact with the concrete surface, thereby achieving a better smoothing effect. The swing mechanism drives the connecting frame to swing, so that the conveyor belt between the smoothing roller and the flattening roller swings and continuously beats the concrete surface, so that the bubbles inside the concrete are discharged under the vibration. At the same time, the beating also makes the surface of the scraped concrete smoother. At the same time, the swing of the driving roller causes the conveyor belt between the flattening roller and the driving roller to continuously squeeze the excess concrete downward. As a result, the excess concrete is continuously pushed forward under the squeezing, thereby better pushing away the excess concrete. The beating of the excess concrete also makes it denser, and if it is filled in a pit during the forward movement, the pit can be filled more tightly.

[0017] The brush can clean the concrete adhering to the conveyor belt surface, and the air or water sprayed from the nozzle can better clean the conveyor belt. It can prevent the adhering concrete from being carried to the bottom surface after the initial leveling and affecting the quality of the floor. It can also prevent the concrete from hardening on the conveyor belt surface and affecting the leveling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Example:

[0025] like Figure 1-Figure 3 As shown, the present invention provides a floor concrete pouring initial leveling device, including an initial leveling head. The initial leveling head includes a driving mechanism, a flattening roller 1, a transmission roller 2 and a transmission belt 3. The initial leveling head also includes a housing 10, and the driving mechanism, the flattening roller 1, the transmission roller 2 and the transmission belt 3 are all arranged inside the housing 10. Figure 2 and 3 As shown, the conveyor belt 3 is sleeved on the flattening roller 1 and the driving roller 2, so that the flattening roller 1 and the driving roller 2 rotate synchronously driven by the conveyor belt 3. The driving mechanism is connected to the flattening roller 1 or the driving roller 2. The driving mechanism can adopt a common motor, and its motor shaft is connected to the rotating shaft of the flattening roller 1 or the rotating shaft of the driving roller 2. Since the driving structure of the motor is common knowledge, it is not described in detail in the specification. The line connecting the flattening roller 1 and the driving roller 2 is inclined to the ground and the driving roller 2 is located above the flattening roller 1. The angle between the line connecting the flattening roller 1 and the driving roller 2 and the ground is an acute angle, so that excess concrete enters the acute angle area and is pushed forward by the conveyor belt 3 between the flattening roller 1 and the driving roller 2. The acute angle setting also allows the excess concrete to be separated and moved to the bottom of the flattening roller 1 during the process of being pushed forward, so that the concrete can enter the gap as much as possible and fill the surface of the concrete densely. Figure 2 and Figure 3 For example, the moving direction of the conveyor belt 3 is clockwise.

[0026] When the floor-specific concrete pouring and leveling device of the present invention is used, the leveling head contacts the concrete surface downward. Driven by an external mechanism, the leveling head gradually moves forward along the concrete surface. At this time, the flattening roller 1 presses the concrete surface through the conveyor belt 3 sleeved on its outside, so that the excess concrete is pushed forward during the movement of the conveyor belt 3, and the conveyor belt 3 also scrapes the ground flat. In order to better smooth the concrete surface, the driving mechanism also drives the flattening roller 1 or the transmission roller 2 to rotate, so that the conveyor belt 3 moves. The conveyor belt 3 fits the concrete surface and moves to smooth the concrete surface. In order to achieve the smoothing of the concrete by the conveyor belt 3, the conveyor belt 3 must move relative to the concrete surface. Therefore, the smoothing effect can be controlled by controlling the rotation speed of the driving mechanism.

[0027] In addition, the flattening roller 1 and the driving roller 2 tension the conveyor belt 3, so that the tensioned conveyor belt 3 is in a plate shape, which can better push the excess concrete forward. The moving direction of the conveyor belt 3 can also be the same as the pushing direction of the concrete, so that the excess concrete is pushed forward by the movement of the initial flattening head and the pushing of the conveyor belt 3, which is better than the prior art that only pushes forward by the scraper.

[0028] In this embodiment, the initial leveling head further includes a smoothing roller 12. The conveyor belt 3 is also connected to the smoothing roller 12. The conveyor belt 3 is parallel to the ground when passing between the flattening roller 1 and the smoothing roller 12. That is, when the flattening roller 1 compacts the ground downward, the smoothing roller 12 also compacts the ground downward. The smoothing roller 12 is added so that the conveyor belt 3 stretched between the flattening roller 1 and the flattening roller 1 can have a larger area to contact the concrete surface, thereby achieving a better smoothing effect.

[0029] In this embodiment, the initial flattening head further comprises a connecting frame 4. The flattening roller 1, the driving roller 2 and the smoothing roller 12 are all connected to the connecting frame 4. Figure 2 and 3 As shown, the connecting frame 4 is hingedly arranged on the base and the rotating shaft of the connecting frame 4 is concentric with the rotating shaft of the flattening roller 1. The connecting frame 4 is also provided with a swing mechanism for driving the swing thereof, so that the conveyor belt 3 between the flattening roller 12 and the flattening roller 1 swings to be parallel to the ground or inclined to the ground, and when inclined to the ground, the distance between the flattening roller 12 and the ground is greater than the distance between the flattening roller 1 and the ground.

[0030] Specifically, the swing mechanism includes an eccentric wheel 8 and a connecting rod 9. The two ends of the connecting rod 9 are respectively hinged to the connecting frame 4 and the eccentric wheel 8. When the motor drives the eccentric wheel 8 to rotate, the connecting rod 9 drives the movable connecting frame 4 to swing.

[0031] When the flat head moves forward, the connecting frame 4 is driven to swing through the swing mechanism, so that the conveyor belt 3 between the smoothing roller 12 and the flattening roller 1 swings and continuously beats the concrete surface, so that the bubbles inside the concrete are discharged under the vibration. At the same time, the beating also makes the surface of the scraped concrete smoother. At the same time, the swing of the driving roller 2 causes the conveyor belt 3 between the flattening roller 1 and the driving roller 2 to continuously squeeze the excess concrete downward. Then the excess concrete is continuously pushed forward under the squeezing, so as to better push away the excess concrete. The beating of the excess concrete also makes it denser. If it is filled in the pit during the forward movement, the pit can be filled more tightly.

[0032] In this embodiment, the initial flattening head further includes a brush 5. The brush 5 is arranged in cooperation with the driving roller 2 so that when the conveyor belt 3 between the smoothing roller 12 and the flattening roller 1 is parallel to the ground, the brush 5 abuts against the surface of the conveyor belt 3. The initial flattening head further includes a plurality of nozzles 6. The plurality of nozzles 6 are distributed along the length direction of the driving roller 2 and the nozzles 6 point to the end of the brush 5.

[0033] The brush 5 can clean the concrete adhered to the surface of the conveyor belt 3, and the gas or water sprayed by the nozzle 6 can better clean the conveyor belt 3. It is prevented that the adhered concrete is brought to the bottom surface after the initial leveling and affects the quality of the floor. At the same time, it is also prevented that the concrete hardens on the surface of the conveyor belt 3 and affects the leveling effect. Generally, the nozzle 6 can clean the conveyor belt 3 by spraying water.

[0034] In addition, driven by the swing mechanism, the conveyor belt 3 continuously contacts the brush 5 and separates the brush 5. During the contact between the two, the extrusion force of the brush 5 on the conveyor belt 3 gradually increases, thereby achieving a good scrubbing effect. When the conveyor belt 3 leaves the brush 5, the water sprayed by the nozzle 6 can rinse the conveyor belt 3 and make the water flow through the gap between the brush 5 and the conveyor belt 3, thereby preventing the concrete from being carried to the smoothing roller 12 through the driving roller 2. The continuous separation and combination of the conveyor belt 3 and the brush 5 also makes the scrubbing of the conveyor belt 3 more thorough.

[0035] In the present embodiment, a moving part 11 is also included. The moving part 11 is in the shape of a trolley, and is provided with rollers so that it can move forward under the rotation of the rollers. The initial leveling head can be raised and lowered on the moving part 11. The moving part 11 is also provided with a lifting mechanism for driving the initial leveling head to rise and fall. Specifically, a vertical guide rail can be provided on the moving part 11. The initial leveling head is connected to the guide rail, and a motor is provided in conjunction with the initial leveling head to drive the initial leveling head to rise and fall. The initial leveling head can be driven to rise and fall by the motor. The depth of the scraping can be adjusted as needed by the lifting and lowering of the initial leveling head, thereby making the surface of the floor flat.

[0036] In this embodiment, the initial leveling head is also provided with a laser distance measuring sensor 7. The laser distance measuring sensor 7 is vertically directed to the ground. The depth of the scraping can be detected and calculated by the laser distance measuring sensor 7, thereby controlling the lifting height of the initial leveling head.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
