Description

Technical Field

[0001] The present invention relates to the field of concrete block preparation, and specifically to a concrete block cutting machine. Background Art

[0002] In the fields of construction and building materials processing, the cutting of concrete bricks is a key process in production and construction. Traditional cutting processes mostly use diamond saw blades (saw strips) or alloy saw blades for mechanical cutting. During this process, the phenomenon of "jamming the saw blade" (i.e., the saw blade is stuck inside the brick body or in the cutting seam) is the main technical problem affecting cutting efficiency, tool life, and construction safety.

[0003] The tooth shapes of traditional diamond saw blades (such as continuous teeth and segment teeth) are prone to chip accumulation due to poor chip evacuation during high-speed cutting, resulting in the saw blade heating up due to friction, which easily leads to saw blade jamming. In addition, the cutting seam generated by the cut concrete brick has a tendency to converge inward. Especially as the cutting seam gradually deepens, this tendency becomes more obvious, and the inward force will increase the friction on the saw blade and also cause saw blade jamming. Summary of the Invention

[0004] The purpose of the present invention is to provide a concrete block cutting machine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A concrete block cutting machine includes a support frame.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a concrete block cutting machine, including a support frame 1, guide columns 2 symmetrically arranged at the four corners of the support frame 1 are provided on the support frame 1, a lifting frame 3 is slidably connected to the guide columns 2, a cutting saw structure 4 is provided on the lifting frame 3, and a dust reduction pipe structure 5 is provided above the cutting saw structure 4;

[0031] The cutting saw structure 4 includes a cutting saw 41, a mounting frame 42 and a guide frame 43. The cutting saw 41 is installed on the mounting frame 42 and is driven to reciprocate horizontally by a motor 44 provided. Through the reciprocating movement of the cutting saw 41, the cutting of the concrete block is realized;

[0032] The mounting frame 42 includes an upper frame body 421 and a lower frame body 422. The cutting saw 41 is installed on the lower frame body 422, the guide frame 43 is installed on two symmetric sides of the lower frame body 422, and the upper frame body 421 and the lower frame body 422 are respectively used to install the cutting saw structure 4 and the dust reduction pipe structure 5;

[0033] The dust reduction pipe structure 5 includes a water pipe 51 and an arc-shaped baffle 52. The water pipe 51 is installed on the upper frame body 421, the arc-shaped baffle 52 is installed directly below the water pipe 51, and the arc-shaped baffle 52 is used to divert the water flowing out of the water pipe 51.

[0034] In this embodiment, the four corners of the lifting frame 3 are slidably connected to the guide columns 2 through guide sleeves, and the guide columns 2 provide guidance for the lifting frame 3.

[0035] In this embodiment, a lifting cylinder 31 is provided above the lifting frame 3. The lifting cylinder 31 is fixedly installed on the support frame 1 through a mounting member. The output shaft of the lifting cylinder 31 is connected to the lifting frame 3. By driving of the lifting cylinder 31, the up and down movement of the lifting frame 3 is realized.

[0036] In this embodiment, a plurality of cutting saws 41 are arranged side by side and at the same height. Both ends of the cutting saw 41 are adjustably installed on the lower layer frame body 422. The number of the cutting saws 41 is set as required, and as many cut blocks as possible can be obtained by one-time cutting.

[0037] In this embodiment, an elastic sheet 411 made of shape memory metal is provided on the top of the cutting saw 41. The elastic sheet 411 includes two groups with the same shape and symmetrically arranged. A through hole 412 is provided on the elastic sheet 411. The material property of the shape memory metal can restore its original shape after no external force acts on itself, so that the elastic sheet 411 can still maintain its elasticity during subsequent cutting.

[0038] In this embodiment, one end of the lower layer frame body 422 is connected to an eccentric cylinder on the turntable 46 through a swing rod 45. The turntable 46 is installed on the output shaft of the motor 44. By driving the turntable 46 to rotate by the motor 44, the turntable 46 drives the swing rod 45 to move back and forth through the eccentric cylinder, and then the cutting saw 41 can be driven to move continuously back and forth.

[0039] In this embodiment, the upper layer frame body 421 and the lower layer frame body 422 are fixedly connected by columns, so that the motor 41 can drive the layer frame body 421 and the lower layer frame body 422 to move together.

[0040] In this embodiment, the guiding frame 43 includes guiding rollers 431. The guiding rollers 431 are slidably connected in a slide rail 432. The slide rail 432 is fixedly installed on the lifting frame 3 to provide guidance for the reciprocating movement of the cutting saw 41.

[0041] In this embodiment, a drip tube 511 is provided below the water pipe 51. Water droplets in the water pipe 51 are dripped onto the arc-shaped baffle 52 through the drip tube 511.

[0042] In this embodiment, the arc-shaped baffle 52 is composed of two groups of arc-shaped plates arranged symmetrically. A drip hole 521 is provided at the middle position of the arc-shaped baffle 52. The arc-shaped baffle 52 is located at the middle line position between two adjacent cutting saws 41 in the vertical direction. When the water flow rate of the water dripping onto the arc-shaped baffle 52 is greater than the water flow rate of the drip hole 521, a part of the water flowing out of the drip tube 511 will flow downward through the arc-shaped plates on both sides to the elastic plate 411 and then flow onto the cutting saw 41 along with the elastic plate 411.

[0043] Working principle: First, place the concrete block under the support frame 1 and at a position where the cutting saw 41 can cut it. Then, start the motor 44 and the lifting cylinder 31 to make both the cutting saw 41 and the lifting frame 3 start running. When the cutting saw 41 cuts the block, as the cutting progresses and the cutting saw 41 penetrates into the block, the elastic piece 411 on the back of the cutting saw 41 will also enter the cutting seam to support the cutting seam and prevent it from closing inward to cause saw jamming. At the same time, the provided water pipe 51 will also make the dripping water flow into the cutting seam to lubricate and cool the cutting saw 41 and achieve the purpose of dust reduction.

[0044] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
