Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a grooving device for house construction. Background Art

[0002] During construction, in some cases when water and electricity installation is involved, it is necessary to groove the ground. A common example is grooving the ground in a workshop, and then placing the wires of the production equipment or the water pipes for heat dissipation in the grooves.

[0003] Existing slotting devices have low slotting efficiency. For example, Chinese Patent Publication No. "CN220881844U" discloses a slotting device for house construction. This device uses grinding to create slots of a certain depth. This means that the device can only grind away the building material bit by bit. This process is relatively slow, and the amount of cutting is large, resulting in low slotting efficiency. Accordingly, the present application proposes a slotting device for house construction. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a grooving device for house construction.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip, and the toothed connecting strip is connected with said toothed connecting strip to form a monolithic structure.

[0007] Preferably, the end of the crushing chisel close to the No. 2 motor is slidably connected to a limiting block, the lower end of the limiting block is slidably connected to a limiting shaft, both ends of the limiting shaft are fixedly connected to protective sleeves, and the bottom end of the limiting block and the inner bottom end of the protective sleeve are fixedly connected to a reset spring.

[0008] Preferably, a push handle is fixedly connected to the rear end of the base, and a roller is fixedly connected to the lower end of the base.

[0009] Preferably, the support frame is fixed to the base by welding, the material of the support frame is ductile iron, and the support frame and the slide groove are formed by casting.

[0010] Preferably, there are two No. 1 motors, and a cutting blade is fixedly provided on each No. 1 motor.

[0011] Preferably, the buffer spring and the return spring have the same specifications.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting up the crushing chisel, the cutting amount of the device is greatly reduced, and the cutting disc can be quickly and easily cut out of the boundary to crush a groove, thereby improving the efficiency of grooving and avoiding the problem of low grooving efficiency caused by excessive cutting amount.

[0014] 2. By setting a push handle and a roller, the device can be pushed and grooves can be easily opened at the same time. Since only the device needs to be pushed and no other operations are required, the user experience of this device is better than that of similar devices. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 The bottom surface of the guide block 13 is fixedly connected to the bottom surface of the guide groove 14, and the bottom surface of the guide block 13 is fixedly connected to the bottom surface of the guide groove 14. The bottom surface of the guide block 13 is fixedly connected to the bottom surface of the guide groove 14, and the bottom surface of the guide block 13 is fixedly connected to the bottom surface of the guide groove 14. The base 1 is located at the rear of the support frame 4 and is fixedly connected to the crushing frame 9. The crushing frame 9 is fixedly connected to a second mounting plate 18. The second mounting plate 18 is fixedly provided with a second motor 20, and a crushing chisel 19 is fixedly provided on the output shaft of the second motor 20. It should be noted that the cutting blade 7 is of prior art, and the second motor 20 is a telescopic motor.

[0023] The end of the crushing chisel 19 closest to the second motor 20 is slidably connected to a limit block 12. The lower end of the limit block 12 is slidably connected to a limit shaft 21. The ends of the limit shaft 21 are fixedly connected to a protective sleeve 15. A return spring 22 is fixedly connected to the bottom end of the limit block 12 and the inner bottom end of the protective sleeve 15. It should be noted that the return spring 22 is used to make the return of the second motor 20 easier and faster.

[0024] The rear end of the base 1 is fixedly connected with a push handle 3, and the lower end of the base 1 is fixedly connected with a roller 2. It should be noted that the interior of the push handle 3 is hollow, which is used to reduce the weight of the device.

[0025] When using the device, first screw the screw 10 to make the cutting blade 7 slide down to the ground, then start the No. 1 motor 6, which will drive the cutting blade 7 to rotate and cut the building. Since there are two cutting blades 7 and two No. 1 motors 6, the cutting blade 7 will cut two boundary gaps during cutting. Then, the push handle 3 is used to push the device so that the bottom end of the crushing chisel 19 is placed between the two boundary gaps, and then start the No. 2 motor 20. Since the No. 2 motor 20 is a telescopic motor, it will cause the crushing chisel 19 to hit the part between the boundary gaps and crush it along the boundary gaps to form a groove.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
