Abstract
Description
Technical Field
[0001] This invention relates to the field of building decoration technology, specifically to an automatic sampling, recycling, and filling device for a leveling robot. Background Technology
[0002] During construction, the surface of cement and concrete pours may be uneven. Therefore, a surface leveling machine is needed to level the cement surface. Leveling robots typically rely on pressure to flatten the uneven ground, thus improving the construction efficiency. However, existing surface leveling machines still have certain shortcomings in their use:
[0003] Because the uniformity of cement putty on the ground is uneven, with both bumps and grooves, existing leveling robots only rely on pressure to flatten the uneven cement putty surface. They cannot collect excess putty and fill it into the areas that need putty filling. This not only leads to differences in the density of cement putty in different areas, resulting in poor leveling effect and the risk of future surface deformation, but also scrapes excess cement putty onto the side of the machine or the end of the driving path, requiring frequent manual adjustments, which is time-consuming, labor-intensive, and results in low work efficiency.
[0004] In view of the above problems, it is very necessary to design an automated sampling, recycling and replenishment device for the whole robot to solve the problems mentioned above. Summary of the Invention
[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an automatic sampling, recycling, and filling device for a leveling robot. This device not only recycles excess putty from the ground and fills it into areas where putty is needed, resulting in high-quality and effective leveling, but also prevents excess cement putty from spreading to the outside of the device, reducing the frequency of manual secondary repairs, saving time, labor, and costs, and greatly improving work efficiency.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.
[0007] This invention provides an automatic sampling, recycling, and filling device for a leveling robot, comprising a leveling structure connected to a main unit for leveling the ground. The leveling structure includes a housing, within which a storage bin and a recycling structure are disposed. The recycling structure is connected to the upper end of the storage bin, and a plurality of feeding pipes are connected to the lower end of the storage bin. The lower openings of the feeding pipes are located on the lower wall of the housing. A PLC controller is disposed within the main unit, and both the recycling structure and the feeding structure are electrically connected to the PLC controller.
[0008] Preferably, the recycling structure includes a drum cylinder, a recycling drum, and a pump body. The drum cylinder has a cylindrical inner cavity and is disposed within a housing. The lower part of the housing near the main unit has an opening that communicates with the inner cavity. The recycling drum is rotatably disposed within the inner cavity of the drum cylinder via a rotating shaft. The length of the recycling drum is the same as the length of the inner cavity, and the axial direction of the drum is horizontally arranged. The pump body is disposed within the housing. The feed end of the pump body is connected to the inner cavity of the drum cylinder via a conduit, and the discharge end of the pump body is connected to the top of the storage tank via a conduit.
[0009] Preferably, a motor is fixedly installed on the side wall of the drum cylinder, and the output shaft of the motor is fixedly connected to the rotating shaft; the motor is electrically connected to the PLC controller.
[0010] Preferably, the side wall of the recycling drum is provided with a plurality of equally spaced baffles, the baffles being parallel to the axial direction of the recycling drum; the end of the baffle away from the recycling drum is always in contact with the inner wall of the inner cavity.
[0011] Preferably, the two bottom walls of the drum cylinder are symmetrically provided with through holes arranged in an arc shape. The center of the through hole is on the axis of the recovery drum, the radius of the arc of the through hole is greater than the radius of the recovery drum, and the radius of the arc of the through hole is less than the radius of the inner cavity. One of the through holes is sealed to the feed end of the pump body through a conduit, and the other through hole connects the inside and outside of the drum cylinder.
[0012] Preferably, the lower openings of the plurality of feeding pipes are arranged in a straight line with equal spacing on the lower wall of the housing, and the straight line is parallel to the axis of the recycling roller; each feeding pipe is connected to a solenoid valve, and the plurality of solenoid valves are electrically connected to a PLC controller respectively.
[0013] Preferably, a through groove is formed on the lower wall of the housing between the feeding pipe and the recycling drum, and the direction of the through groove is parallel to the axis of the recycling drum; a plurality of rangefinders are arranged at equal intervals in the through groove, and the working direction of the rangefinders is perpendicular to the lower wall of the housing; the plurality of rangefinders are electrically connected to the PLC controller respectively, and the number of rangefinders is the same as the number of solenoid valves and corresponds one-to-one.
[0014] The specific advantages of the automatic sampling, recycling, and filling device for a leveling robot of the present invention are as follows:
[0015] 1. This invention uses a baffle plate on the recovery drum to transfer excess cement putty into the inner cavity of the drum cylinder. The strong negative pressure of the pump body discharges the excess cement putty into the storage bucket for secondary use. This not only saves costs, but also prevents excess cement putty from spreading to the outside of the device, reduces the frequency of manual secondary repair, saves time and labor, and greatly improves work efficiency.
[0016] 2. This invention uses multiple rangefinders to monitor the distance between the surface of the cement putty on the ground directly below and the rangefinders in real time. If the distance is greater than a set value, it indicates that the ground is concave at that location and needs to be replenished with cement putty. Based on the current travel speed of the device and the distance between the rangefinders and the solenoid valves, the delay time for the PLC controller to issue a command is calculated. The PLC controller controls the corresponding solenoid valve to open, discharging some cement putty from the discharge bucket onto the concave ground. This invention can automatically fill the areas that need to be filled with putty, resulting in a smooth and high-quality flat surface. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example:
[0030] like Figures 1 to 8 As shown, this invention provides an automatic sampling, recycling, and filling device for a leveling robot, including a main unit 1 and a connecting bracket 2 connected to the side wall of the main unit 1. A leveling structure 3 for leveling the ground is connected to the connecting bracket 2. The leveling structure 3 includes a housing 4, within which a storage bin 5 and a recycling structure 6 are disposed. The recycling structure 6 is used to recycle excess cement putty from the ground and temporarily stores the recycled cement putty in the storage bin 5. The recycling structure 6 is connected to the upper end of the storage bin 5, and several discharge pipes 7 are connected to the lower end of the storage bin 5. The lower openings of the discharge pipes 7 are located on the lower wall of the housing 4. A PLC controller is disposed inside the main unit 1, and both the recycling structure 6 and the discharge structure are electrically connected to the PLC controller. The PLC controller can control the operation of the recycling structure 6 and the discharge structure.
[0031] As a further embodiment of the present invention: the recycling structure 6 includes a drum cylinder 8, a recycling drum 9, and a pump body 10. The drum cylinder 8 has a cylindrical inner cavity 11. The drum cylinder 8 is disposed inside the housing 4. The lower part of the housing 4 near the main unit 1 has an opening that communicates with the inner cavity 11. The recycling drum 9 is rotatably disposed in the inner cavity 11 inside the drum cylinder 8 via a rotating shaft. The length of the recycling drum 9 is the same as the length of the inner cavity 11. The axial direction of the drum is horizontally arranged. The pump body 10 is disposed inside the housing 4. The feed end of the pump body 10 is connected to the inner cavity 11 of the drum cylinder 8 via a conduit 12. The discharge end of the pump body 10 is connected to the top of the storage tank 5 via a conduit 12.
[0032] As a further embodiment of the present invention: a motor 13 is fixedly installed on the side wall of the drum cylinder 8, and the output shaft of the motor 13 is fixedly connected to the rotating shaft; the motor 13 is electrically connected to the PLC controller, and under the control of the PLC controller, the speed at which the motor 13 drives the recycling drum 9 to rotate can be adjusted to adjust the recycling rate of cement putty, which is suitable for various working conditions.
[0033] As a further embodiment of the present invention: a plurality of equally spaced lever plates 14 are arranged circumferentially on the side wall of the recycling roller 9, and the lever plates 14 are parallel to the axial direction of the recycling roller 9; the end of the lever plate 14 away from the recycling roller 9 is always in contact with the inner wall of the inner cavity 11, and the recycling roller 9 rotates to bring cement putty into the inner cavity 11 through the multiple lever plates 14.
[0034] As a further embodiment of the present invention: Symmetrically arranged arc-shaped through holes 15 are provided on the two bottom walls of the drum cylinder 8. The center of the arc of the through hole 15 is on the axis of the recovery drum 9. The radius of the arc of the through hole 15 is greater than the radius of the recovery drum 9, and the radius of the arc of the through hole 15 is less than the radius of the inner cavity 11. One of the through holes 15 is sealed to the feed end of the pump body 10 through a conduit 12, and the other through hole 15 connects the inside and outside of the drum cylinder 8. The length of the recovery drum 9 is the same as the length of the inner cavity 11. When the pump body 10 is powered on, the space formed between the side wall of the recovery drum 9 and the inner cavity 11 instantly becomes a negative pressure space. The cement putty in this negative pressure space enters the storage tank 5 through the through hole 15 connected to the conduit 12 and the conduit 12. The function of the other through hole 15 is to allow air from outside the drum cylinder 8 to enter the negative pressure space.
[0035] As a further embodiment of the present invention: the lower openings of several feeding pipes 7 are arranged in a straight line with equal spacing on the lower wall of the housing 4, and the straight line is parallel to the axis of the recycling roller 9; each feeding pipe 7 is connected to a solenoid valve 16, and several solenoid valves 16 are electrically connected to a PLC controller. A through groove 17 is formed on the lower wall of the housing 4 between the feeding pipes 7 and the recycling roller 9, and the direction of the through groove 17 is parallel to the axis of the recycling roller 9; several rangefinders 18 are arranged in the through groove 17 with equal spacing, and the working direction of the rangefinders 18 is perpendicular to the lower wall of the housing 4; several rangefinders 18 are electrically connected to the PLC controller, and the number of rangefinders 18 is the same as the number of solenoid valves 16 and corresponds one-to-one.
[0036] Multiple rangefinders 18 monitor the distance between the surface of the cement putty on the ground directly below and the rangefinder 18 in real time. If the distance value is greater than the set value, it means that the ground is in a concave state at that position and cement putty needs to be added. Based on the current travel speed of the device and the distance between the rangefinder 18 and the solenoid valve 16, the delay time for the PLC controller to issue a command is calculated. The PLC controller controls the corresponding solenoid valve 16 to open and discharge some cement putty from the discharge bucket onto the concave ground.
[0037] Working principle: When the operator turns on the main unit 1, the main unit 1 drives the flat structure 3 to move slowly and evenly against the ground through the connecting bracket 2. The PLC controller controls the motor 13 and the pump body 10 to work, and the recycling drum 9 rotates.
[0038] During the movement of the housing 4, the hanging plate on the recycling roller 9 transfers the excess (higher) cement putty to the inner cavity 11. The space formed between the side wall of the recycling roller 9 and the inner cavity 11 instantly becomes a negative pressure space. The cement putty in this negative pressure space enters the storage tank 5 through the through hole 15 connected to the conduit 12. The function of the other through hole 15 is to allow air from outside the roller cylinder 8 to enter the negative pressure space.
[0039] During the movement of the housing 4, multiple rangefinders 18 monitor the distance between the surface of the cement putty on the ground directly below it and the rangefinder 18 in real time. If the distance value is greater than the set value, it indicates that the ground is concave at that position and cement putty needs to be added. At this time, the rangefinder 18 sends an electrical signal to the PLC controller. The PLC controller calculates the delay time for issuing the command based on the current travel speed of the device and the distance between the rangefinder 18 and the solenoid valve 16. The PLC controller controls the corresponding solenoid valve 16 to open, discharging part of the cement putty in the discharge bucket onto the concave ground. This invention can automatically fill the position that needs to be filled with putty, resulting in a high-quality and excellent leveling effect.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
