Description

Technical Field

[0001] This utility model relates to the field of grooving equipment technology, and in particular to an adjustable multi-blade grooving device. Background Technology

[0002] Grooving equipment is mainly used for repairing asphalt and cement pavements, as well as for installing drainage pipes, gas pipes, electrical conduits, and fiber optic cables. A circular saw quickly cuts the pavement into uniform grooves, creating new bonding surfaces. This optimizes the contact surface between the grouting material and the groove, strengthening the bond between the grouting material and the groove sidewalls.

[0003] As a common building material processing tool, the core function of a grooving machine is to cut grooves of a specific width and depth on the surface of the material. The grooving width is a key parameter in the processing and needs to be adjusted frequently according to different usage requirements. Most existing operating methods combine multiple thin blades and shims to achieve the required width, which is cumbersome and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in adjusting the grooving width in the prior art, and to propose an adjustable multi-blade grooving device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable multi-blade grooving device includes a grooving assembly installed on the lower surface of a mobile vehicle. The grooving assembly is close to the front end of the mobile vehicle. The grooving assembly includes a hollow shaft rotatably disposed on the lower surface of the mobile vehicle and a plurality of cutting blades sleeved on the surface of the hollow shaft. The distance between the multiple cutting blades is adjusted by a spacing adjustment component, which includes an inclined block fixedly connected to the center of the cutting blade and an adjustment block vertically slidably disposed on one side of the cutting blade. The hollow shaft surface is provided with a first blocking cover and a second blocking cover for limiting the total length of the multiple cutting blades.

[0006] In some embodiments, the inclined surface of the inclined block faces the center of the cutting blade, and the side of the adjusting block away from the cutting blade is provided with an inclined surface that cooperates with the inclined block.

[0007] In some embodiments, a through groove is provided on the surface of the hollow shaft, and the lower ends of the adjusting block and the inclined block are slidably disposed on the inner wall of the through groove. A camshaft for driving the adjusting block to slide upward is rotatably disposed inside the hollow shaft, and the camshaft is driven to rotate through a transmission assembly.

[0008] In some embodiments, the transmission assembly includes two gears, which are respectively fixedly connected to one end of the camshaft and one end of the connecting shaft, and the two gears mesh with each other. The connecting shaft is rotatably disposed at the end of the hollow shaft.

[0009] In some embodiments, a limiting wheel is fixedly connected to the surface of the connecting shaft, and a plurality of limiting holes are evenly opened on the surface of the limiting wheel. A limiting rod that mates with the limiting holes is threadedly connected to the surface of the hollow shaft.

[0010] In some embodiments, the first barrier is fixedly connected to one end of the hollow shaft near the transmission assembly, and the first barrier is stepped.

[0011] In some embodiments, the second blocking cover is sleeved on the end of the hollow shaft away from the transmission component. The second blocking cover is stepped and is fixedly connected to the surface of the hollow shaft by a plurality of fastening bolts.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-8 An adjustable multi-blade grooving device includes a grooving assembly 2 installed on the lower surface of a mobile vehicle 1. The grooving assembly 2 is close to the front end of the mobile vehicle 1. The grooving assembly 2 includes a hollow shaft 202 rotatably disposed on the lower surface of the mobile vehicle 1 and a plurality of cutting blades 201 sleeved on the surface of the hollow shaft 202. A diesel engine is fixedly connected to the upper surface of the mobile vehicle 1. One end of the output shaft of the diesel engine and one end of the hollow shaft 202 are respectively fixedly connected to pulleys, and the two pulleys are driven by belts. It is understandable that the diesel engine works, and the belt and pulley drive the hollow shaft 202 and multiple cutting blades 201 to rotate, thereby causing the multiple cutting blades 201 to groove. During the grooving process, the moving vehicle 1 drives the grooving assembly 2 to move, so as to achieve the purpose of continuous grooving.

[0029] Specifically, the distance between multiple cutting blades 201 is adjusted by the spacing adjustment component 3. The spacing adjustment component 3 includes a wedge block 301 fixedly connected to the center of the cutting blade 201 and an adjustment block 302 vertically slidably disposed on one side of the cutting blade 201. The adjustment block 302 is vertically slidably disposed via a guide rail, which is fixedly connected to one side of the cutting blade 201. The inclined surface of the wedge block 301 faces the center of the cutting blade 201. The side of the adjustment block 302 away from the cutting blade 201 is provided with an inclined surface that cooperates with the wedge block 301. When the adjustment block 302 slides upward, the cooperation of the two inclined surfaces can make the two cutting blades 201 move away from each other. A through groove is provided on the surface of the hollow shaft 202. One end of the through groove is located at the end of the hollow shaft 202 away from the pulley. The lower end of the adjusting block 302 and the lower end of the inclined block 301 are slidably disposed on the inner wall of the through groove. A cam shaft 303 is rotatably disposed inside the hollow shaft 202 to drive the adjusting block 302 to slide upward. The cam shaft 303 is driven to rotate through the transmission assembly 304.

[0030] It is understandable that when installing the cutting blade 201, the inclined block 301 and the adjusting block 302 are aligned with the through slot, so that the cutting blade 201 is slidably set on the surface of the hollow shaft 202 through the inclined block 301 and the adjusting block 302. The cooperation between the inclined block 301 and the through slot can make the hollow shaft 202 drive the cutting blade 201 to rotate. After the cutting blade 201 is installed, the inclined surface of the inclined block 301 contacts the inclined surface of the adjusting block 302. By rotating the camshaft 303, the changing arc shape of the surface of the camshaft 303 pushes the adjusting block 302 to slide upward. With the cooperation of the two inclined surfaces, the two cutting blades 201 are moved away from each other, thereby adjusting the total length of the grooving assembly 2, so as to facilitate the adjustment of the grooving width.

[0031] Specifically, the transmission assembly 304 is located at the end of the hollow shaft 202 near the pulley. The transmission assembly 304 includes two gears 3041, which are fixedly connected to one end of the camshaft 303 and one end of the connecting shaft 3042, respectively. The two gears 3041 mesh with each other. The connecting shaft 3042 is rotatably disposed at the end of the hollow shaft 202. A handle is fixedly connected to the outer end of the connecting shaft 3042. The diameter of the gears 3041 on the surface of the connecting shaft 3042 is smaller than the diameter of the gears 3041 on the surface of the camshaft 303. A limiting wheel 3043 is fixedly connected to the surface of the connecting shaft 3042. Multiple limiting holes 3044 are evenly opened on the surface of the limiting wheel 3043. A limiting rod 3045 that mates with the limiting holes 3044 is threadedly connected to the surface of the hollow shaft 202.

[0032] It is understandable that the rotating handle drives the connecting shaft 3042 and the pinion 3041 to rotate, which in turn drives the large gear 3041 and the camshaft 303 to rotate. This allows the camshaft 303 to adjust the spacing between the cutting blades 201. Gears 3041 of different diameters can change the transmission ratio of the connecting shaft 3042 to the camshaft 303, allowing for more precise rotation of the camshaft 303. By setting a limiting wheel 3043 and a limiting rod 3045, rotating the limiting rod 3045 causes it to insert into the inner wall of the limiting hole 3044, thereby limiting the rotation of the limiting wheel 3043 and the connecting shaft 3042, and ultimately limiting the spacing between the camshaft 303 and the cutting blades 201.

[0033] Specifically, a first blocking cover 4 is fixedly connected to the surface of the hollow shaft 202. The first blocking cover 4 is stepped and is located at one end of the hollow shaft 202 near the transmission assembly 304. A second blocking cover 5 is fitted on the surface of the hollow shaft 202. The second blocking cover 5 is stepped and is located at the end of the hollow shaft 202 away from the transmission component 304. The second blocking cover 5 is fixedly connected to the surface of the hollow shaft 202 by a plurality of fastening bolts 501.

[0034] It is understandable that by setting the first blocking cover 4 and the second blocking cover 5, the total length of the multiple cutting blades 201 is limited. By using the first blocking cover 4 as a reference plane, the position of the second blocking cover 5 is adjusted, and the distance between the first blocking cover 4 and the second blocking cover 5 is adjusted, thereby limiting the total length of the multiple cutting blades 201.

[0035] Specifically, the surface of the mobile vehicle 1 is provided with a height adjustment component 6 for adjusting the cutting depth. The height adjustment component 6 includes an adjustment frame 601 rotatably disposed on the surface of the mobile vehicle 1 and two support wheels 602 rotatably disposed at one end of the adjustment frame 601. The support wheels 602 are located in the middle of the mobile vehicle 1, the hinge shaft of the adjustment frame 601 is located in the middle of the adjustment frame 601, and two moving wheels are provided on the lower surface of the mobile vehicle 1. Both moving wheels are located at the rear end of the mobile vehicle 1. The adjusting frame 601 is driven to swing through the threaded tube 603 and the threaded rod 604. The threaded tube 603 is vertically slidably disposed at the rear end of the moving vehicle 1. The threaded rod 604 is threadedly connected to the inner wall of the threaded tube 603 and is rotatably disposed on the surface of the moving vehicle 1. A handwheel is fixedly connected to the upper end of the threaded rod 604. Two swing shafts 605 are symmetrically fixedly connected to the lower end of the threaded tube 603. Two elongated holes are opened at the end of the adjusting frame 601 away from the support wheel 602. The two swing shafts 605 are disposed on the inner wall of the two elongated holes.

[0036] Understandably, by rotating the threaded rod 604 via the handwheel, the threaded tube 603 moves up and down. Under the action of the elongated hole and the swing shaft 605, the adjusting frame 601 swings, adjusting the height of the support wheel 602. This causes the moving carriage 1 to tilt the cutting assembly downwards or upwards, thus facilitating the adjustment of the cutting depth.

[0037] Specifically, a dust cover 7 is vertically slidable at the front end of the mobile vehicle 1, and two rollers 701 are provided at the bottom of the dust cover 7.

[0038] It is understandable that by setting up the dust cover 7, the splashes generated during the grooving process of the cutting disc 201 can be blocked, thus achieving a protective effect and reducing dust dispersion.

[0039] In this invention, a diesel engine operates, driving the hollow shaft 202 and multiple cutting blades 201 to rotate via a belt and pulley. This causes the cutting blades 201 to perform grooving. When the grooving depth needs adjustment, a handwheel drives the threaded rod 604 to rotate, causing the threaded tube 603 to swing the adjusting frame 601, thus adjusting the height of the support wheel 602 and the cutting depth. During the grooving process, the moving carriage 1 moves the grooving assembly 2 to achieve continuous grooving. When the grooving width needs adjustment, the position of the second blocking cover 5 is first adjusted, ensuring the distance between the second blocking cover 5 and the first blocking cover 4 matches the required grooving width. The second blocking cover 5 is then secured with fastening bolts 501. The position is fixed, and then the limiting rod 3045 is released from the limiting wheel 3043, so that the connecting shaft 3042 drives the small gear 3041 to rotate, thereby driving the large gear 3041 and the camshaft 303 to rotate. The rotation of the camshaft 303 can drive the adjusting block 302 to slide upward. With the cooperation of the two inclined planes, the adjacent cutting pieces 201 are moved away from each other, and multiple cutting pieces 201 move towards the second blocking cover 5. When the cutting pieces 201 located on both sides abut against the surfaces of the first blocking cover 4 and the second blocking cover 5 respectively, the limiting rod 3045 limits the limiting wheel 3043 and limits the angle of the camshaft 303, and finally limits the total length of the cutting pieces 201, so as to facilitate the adjustment of the slot width.
