Description

Technical Field

[0001] This utility model belongs to the technical field of mortar leveling devices, specifically relating to a material tray structure. Background Technology

[0002] In the process of leveling the ground with mortar, the mortar needs to be spread and leveled in advance using a mixer to mix the mortar, such as gypsum-based or cement-based materials, with water. Then, it is transported to the ground through pipelines, or the mixer is pushed to pour semi-dry material. Then, it is automatically or manually leveled. During the construction process using a troweling device, due to structural defects in the troweling tray, the semi-dry material is prone to accumulate and overflow, resulting in poor leveling effect and an unsightly coating.

[0003] Therefore, it is necessary to improve the tray structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a material tray structure. Through the design of the material tray structure, a smooth coating can be formed evenly, thereby improving the quality and efficiency of leveling construction operations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a material tray structure, including a material tray body, wherein the material tray body includes:

[0006] A rotary support device, comprising a rotating disk and a rotary support motor, wherein the rotary support motor drives the rotating disk to rotate and smooth the semi-dry material.

[0007] A fixed sleeve is installed coaxially with the rotating disk, and the rotary support motor is fixed on the fixed sleeve.

[0008] In one feasible implementation, a discharge port is set at the center of the tray body.

[0009] In one feasible implementation, the discharge port is connected to a conical hopper via a conveying auger, and the conveying auger is connected to a flexible pipe that connects to the central discharge port of the material tray.

[0010] In one feasible implementation, the fixing sleeve includes an outer ring and a central ring, with spokes symmetrically arranged between the outer ring and the central ring. The central axis of the central ring overlaps with the central axis of the fixing sleeve. The bottom of the outer ring has a serrated structure, and symmetrical openings are made on the bottom sidewall of the outer ring.

[0011] In one feasible implementation, the opening is a waist-shaped opening.

[0012] In one feasible implementation, the bottom of the rotating disk is concave, and the bottom surface is provided with arc-shaped grooves radiating outward from the center, with the arc-shaped grooves gradually narrowing outward from the center.

[0013] In one feasible implementation, symmetrical circular holes are also provided on the rotating disk as ventilation holes during the smoothing of semi-dry materials.

[0014] The beneficial effects of this utility model are as follows: The material tray structure of this utility model adopts the design of rotating disk and fixed sleeve to form an independent material cavity under the fixed sleeve. When smoothing semi-dry material, overflow is reduced. The serrated edge structure also effectively reduces the phenomenon of uneven coating. Attached Figure Description

[0020] See Figures 1-3 In the embodiments of this application, a material tray structure is provided for use on a smoothing machine. The smoothing machine includes a vehicle body 1, a feeding device, and a smoothing device. The feeding device is installed on the upper part of the vehicle body. The smoothing device includes an up-and-down adjustment mechanism, a material tray 2, and a left-and-right swinging device. The material tray is installed at the front end of the vehicle body. Through the up-and-down adjustment mechanism and the left-and-right swinging mechanism, the material tray can move up and down, swing left and right, and rotate itself to achieve smoothing of semi-dry material. The discharge port of the feeding device is connected to the central pipe of the material tray, and the material is fed through a metering pump.

[0021] The up-and-down adjustment mechanism includes a mounting plate, a servo cylinder, a transmitter, and a detector. The detector is mounted on the mounting plate, and the transmitter is mounted on the ground. In this embodiment, the transmitter uses a laser leveling instrument of model LESUN526, and the detector uses a laser receiver LS712-CAN. The mounting plate is connected to and mounted with a servo cylinder, which enables the mounting plate to move up and down in the vertical direction, thus adjusting the distance between the material tray and the semi-dry material.

[0022] In this embodiment, the vehicle body includes a frame, a first set of wheels and a second set of wheels installed at the front and rear of the bottom of the frame, and a first drive component for driving the first set of wheels. The frame includes a base plate and a frame mounted on the upper part of the base plate.

[0023] The feeding device described in this embodiment includes a conical hopper 3, which is fixed on the frame. The outlet of the hopper is connected to the inlet of the conveying auger. The conveying auger is fixedly installed on the base plate, and the outlet of the conveying auger is connected to one end of a flexible pipe. The other end of the flexible pipe is installed at the center of the material tray 4.

[0024] In this embodiment, the left and right swinging mechanism includes an L-shaped cantilever. The material tray is fixed to one end of the L-shaped cantilever. The bottom of the material tray is flush with or higher than the bottom of the traveling wheel. The other end of the L-shaped cantilever is provided with a vertical movement drive device and a left and right swinging device. Driven by the vertical movement drive device and the left and right swinging device, the L-shaped cantilever drives the material tray to move up and down and swing left and right.

[0025] The left-right swing mechanism in this embodiment also includes a first rotary support. The cantilever swings left and right around the axis of the first rotary support, so that the cantilever drives the material tray to swing left and right in the horizontal direction. The first rotary support is fixed to the mounting plate.

[0026] In this embodiment, the material tray includes a rotating disk 5 and a fixed sleeve 12. The rotating disk and the fixed sleeve are coaxially installed. The fixed sleeve is fixedly connected to one end of the L-shaped cantilever. The rotating disk is connected to a rotary support motor 6 and is driven to rotate by the rotary support motor.

[0027] In this embodiment, a reinforcing plate is also provided at the connection between the fixing sleeve and the L-shaped cantilever.

[0028] In one feasible implementation, the fixing sleeve includes an outer ring 7 and a central ring, with spokes 8 symmetrically arranged between the outer ring and the central ring. The central axis of the central ring overlaps with the central axis of the fixing sleeve. The bottom of the outer ring has a serrated structure 9, and symmetrical holes 10 are opened on the bottom sidewall of the outer ring.

[0029] In one feasible implementation, the opening is a waist-shaped opening.

[0030] In this embodiment, the bottom of the rotating disk is concave, and the bottom surface is provided with arc-shaped grooves 11 radially from the center outward, and the arc-shaped grooves gradually narrow from the center outward.

[0031] The construction method of applying the material tray structure of this utility model to a troweling machine includes the following steps: S1, the first driving component motor drives the vehicle body to move;

[0032] S2, the amount of material fed by the metering pump is controlled through actual construction;

[0033] S3, by controlling the servo electric cylinder to move up and down, the first rotary support to swing left and right, and the second rotary support motor to rotate the material tray, the semi-dry material falling from the hopper to the ground is smoothed out.

[0034] This utility model features a material tray structure with a laser level microsystem consisting of a transmitter and a detector. This ensures the material tray remains in close contact with the semi-dry material surface for smoothing. A servo electric cylinder precisely moves and adjusts the mounting plate, thus regulating the distance between the material tray and the semi-dry material, reducing spillage or idle running during smoothing. This utility model also achieves metered material feeding and automatic tray adjustment based on uneven ground, ensuring a smooth and aesthetically pleasing coating.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
