Description

Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a trowel machine with a size-changing function. Background Art

[0002] A floor trowel, also known as a cement finishing machine, consists of a trowel rotor driven by an electric motor or gasoline engine. Two to four trowels are mounted on the cross-shaped base of the rotor. Existing trowels are categorized by their working mechanism into two main types: disc trowels and blade trowels. Blade trowels are available in either single or double trowel heads. They are also divided into two types based on power: electric and internal combustion. Disc trowels are primarily used for concrete slurry preparation and smoothing, while blade trowels are primarily used for finishing during subsequent concrete construction. They offer high-quality and efficient concrete floor construction machinery.

[0003] For safety reasons, trowels are generally equipped with protective nets when in use. Trowels of different sizes are required to perform troweling work according to different terrains to improve work efficiency. The sizes of protective nets of common trowels on the market are generally fixed. When replacing trowels of different sizes, they may not be suitable. In addition, the blades of common trowels on the market are fixedly installed, which makes it inconvenient to adjust the angle of the blades and cannot be well adapted to troweling work at different angles.

[0004] To this end, we propose a trowel with a size-changing function. Utility Model Content

[0005] The purpose of the present utility model is to provide a trowel with a size-changing function to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a trowel with a size conversion function, comprising a protective frame and a mounting assembly, wherein the mounting assembly is mounted on the outside below the protective frame, and the mounting assembly is used to facilitate the conversion of the size of the trowel blade. The mounting assembly comprises a second protective ring, which is mounted below the protective frame, and the first protective ring is placed on the outer ring of the second protective ring. Several card slots are provided on the upper surface of the second protective ring, and several card blocks adapted to the size of the card slots are fixedly mounted on the inner ring of the first protective ring.

[0007] An adjusting assembly is installed inside the lower part of the protective frame, and the adjusting assembly is used to facilitate adjusting the troweling angle of the trowel blade during operation of the trowel, and the adjusting assembly includes a power assembly, the power assembly is fixedly installed on the bottom surface of the protective frame, the output shaft of the power assembly is fixedly installed with a threaded rod, the bottom end of the threaded rod is fixedly connected to the rotating disk, and four evenly distributed mounting blocks are fixedly installed on the bottom surface of the rotating disk, and a trowel piece is fixedly installed on the side of each of the mounting blocks, and four groups of clamping rods are clamped on the upper surface of the rotating disk, and the bottom surface of each group of clamping rods is fixedly connected to a push rod, and each push rod is respectively in contact with the trowel piece corresponding thereto, and the upper surface of each group of clamping rods is fixedly connected to a fixing plate, and an elastic steel plate is fixedly installed between each fixing plate and the upper surface of the rotating disk.

[0008] Preferably, a plurality of protective sheets adapted to the positions of the blocking blocks are fixedly connected to the upper surface of the second protective ring.

[0009] Preferably, a handrail is fixedly mounted on the left side of the protective frame.

[0010] Preferably, each of the mounting blocks is connected to the rotating disk by screws.

[0011] Preferably, the outer surface of the threaded rod is threadedly connected to a top plate, and the bottom surface of the top plate is in contact with the upper surfaces of the four fixing plates.

[0012] Preferably, a plurality of handles are installed on the upper surface of the top plate.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. When it is necessary to replace the trowels of different sizes, first unscrew the screws on the bottom of the mounting block. At this time, the mounting block and the push rod can be removed from the bottom of the rotating disk, and then the trowel of appropriate size is installed on the bottom of the rotating disk through the mounting block. At this time, the first protective ring is put on the outer ring of the second protective ring, and then the first protective ring is rotated in the positive direction as a whole so that the card block is stuck in the inside of the card slot, and then the card block is hit downward with a hammer or other tools to make the card block firmly stuck in the inside of the card slot. At this time, the position of the first protective ring can be firmly fixed. When the first protective ring needs to be removed, it only needs to hit the card block upward and then rotate the first protective ring in the opposite direction to remove the first protective ring as a whole.

[0015] By providing the installation assembly, the first protective ring can be easily disassembled or installed as a whole, and further, the size of the entire device can be easily changed.

[0016] 2. When the angle of the trowel needs to be adjusted, hold the handle with your hand and rotate the top plate in the positive direction. The top plate can be lowered as a whole through the threaded connection between the top plate and the threaded rod. At this time, the ejector rod can be stably lowered through the clamping connection between the clamping rod and the rotating disk. At this time, the ejector rod will push the trowel, and then the trowel will be deformed, further improving the effect of adjusting the angle of the trowel.

[0017] By setting the adjustment component, the angle of the trowel blade can be easily adjusted, which solves the problem that it is inconvenient to adjust the angle of the trowel blade and it cannot be well applied to trowel work at different angles. BRIEF DESCRIPTION OF THE DRAWINGS
