Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a multi-purpose roughening device. Background Technology
[0002] In the field of building construction, in order to ensure a tight bond between new and old concrete at different construction stages, the old concrete substrate surface needs to be roughened to remove laitance, loose stones, and weak concrete soil layers, thereby increasing the bonding strength between the new and old concrete surfaces.
[0003] In existing technologies, scabbing machines rely on rotating chisels to roughen old concrete. However, the chisels move horizontally with the old concrete, and the old concrete that has not been roughened and that has been roughened forms a stepped platform. This platform can block the movement of the chisels, requiring greater force to move the scabbing machine. At the same time, the scabbing process generates a lot of dust and gravel, polluting the surrounding environment. Moreover, in some dry areas, it is necessary to keep the roughened old concrete moist. Utility Model Content

[0036] Example 1
[0037] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a multi-purpose chiseling device that can simultaneously perform rotary chiseling and hammer chiseling on concrete, thereby achieving a better chiseling effect.
[0038] Specifically, including,
[0039] The body 100 includes an outer shell 101, a rotating cavity 101a disposed inside the outer shell 101 and penetrating the upper and lower surfaces of the outer shell 101, a rotating component 102 disposed inside the rotating cavity 101a, a guide component 103 disposed above the rotating component 102, and a power component 104 disposed above the guide component 103 and capable of driving the rotating component 102 to rotate.
[0040] The chiseling unit 200 includes a chiseling component 201.
[0041] Furthermore, the rotating assembly 102 includes an internal gear 102a, a vertically symmetrical connecting plate 102b, and three spur gears 102c evenly distributed in a ring.
[0042] The connecting plate 102b is rotatably connected to the lower end of the rotating cavity 101a and sealed by a rubber ring. The internal gear 102a is installed between the connecting plates 102b and fixedly connected to the rotating cavity 101a. The connecting plate 102b has three mounting holes 102b-1 that penetrate the upper and lower surfaces of the connecting plate 102b and are evenly distributed in an annular pattern. The spur gear 102c meshes with the internal gear 102a. The spur gear 102c is rotatably connected to the mounting holes 102b-1 and sealed by a rubber ring. The spur gear 102c has a cross sliding hole 102c-1 that penetrates the upper and lower surfaces of the spur gear 102c.
[0043] Furthermore, the chiseling assembly 201 includes a cross sliding shaft 201a and a conical chisel head 201b;
[0044] The cross sliding shaft 201a is slidably connected to the cross sliding hole 102c-1, and the lower end of the cross sliding shaft 201a is connected to the top end of the conical chisel 201b by a thread.
[0045] Furthermore, the guide assembly 103 includes a guide ramp 103a and a semi-circular guide slider 103b;
[0046] The guide ramp 103a is connected to the rotating cavity 101a by a thread, and the semi-circular guide slider 103b is connected to the top end of the cross sliding shaft 201a by a thread. The arc surface of the semi-circular guide slider 103b is slidably connected to the inclined surface of the guide ramp 103a.
[0047] Furthermore, the guide assembly 103 also includes a return spring 103c;
[0048] The reset spring 103c is installed between the semi-circular guide slider 103b and the spur gear 102c.
[0049] Furthermore, the power assembly 104 includes a first motor 104a and a drive shaft 104b;
[0050] The first motor 104a is mounted on the upper surface of the guide inclined plate 103a, and the drive shaft 104b is mounted on the first motor 104a. The drive shaft 104b passes through the guide inclined plate 103a and is fixedly connected to the connecting plate 102b. The drive shaft 104b and the guide inclined plate 103a are sealed by a rubber ring.
[0051] It should be noted that the spur gear, cross sliding shaft, guide ramp, and semi-circular guide slider are all made of wear-resistant materials, thereby improving their service life.
[0052] When in use, the first motor is started, which drives the connecting plate to rotate through the transmission shaft. At the same time, the spur gear mounted on the connecting plate rotates in a circular motion. Simultaneously, the spur gear meshes with the internal gear and rotates on its own axis. Meanwhile, the semi-circular guide slider is pressed tightly against the inclined surface of the guide plate under the action of the return spring. This causes the cross sliding shaft to move up and down with the undulation of the inclined surface and under the restriction of the cross sliding hole. This drives the conical chisel head to make a circular motion while rotating and moving up and down to chisel the concrete.
[0053] In summary, the conical chisel head of this invention, through the combined action of the drive component, the rotating component, and the guide component, achieves both rotation and circular motion, as well as vertical movement. This allows the chisel head to form an inclined cutting plane during operation, enabling the concrete to be roughened gradually at an angle. This reduces the roughening stress and avoids the problem of traditional roughening equipment creating stepped cutting marks on the concrete, requiring workers to exert considerable force to push the equipment forward. Simultaneously, the vertical movement of the chisel head also impacts the ground, achieving simultaneous rotary roughening and hammer roughening for a better roughening effect.
[0054] Example 2
[0055] Reference Figures 6-7 This is the second embodiment of the present invention, which differs from the first embodiment in that it can spray water to moisten the concrete and prevent dust from splashing when roughening the concrete. At the same time, it can also evenly mix the moisturizer into the water, so that it can be evenly sprayed on the concrete surface under the action of the centrifugal force of the rotating conical chisel, thereby achieving the function of moisturizing the newly roughened concrete.
[0056] Specifically, the chisel assembly 201 includes a cross sliding shaft 201a and a conical chisel head 201b;
[0057] The cross sliding shaft 201a is slidably connected to the cross sliding hole 102c-1, and the lower end of the cross sliding shaft 201a is connected to the top end of the conical chisel 201b by a thread.
[0058] Furthermore, the cooling assembly 202 includes a stirring blade 202a, a first channel 201a-1 disposed inside the cross sliding shaft 201a and opening downward, a water inlet hole 201a-2 disposed at the upper end of the first channel 201a-1 and penetrating the surface of the cross sliding shaft 201a, and a uniformly distributed cavity 201b-1 disposed inside the conical chisel 201b and communicating with the first channel 201a-1;
[0059] The stirring blade 202a is mounted on the drive shaft 104b.
[0060] Furthermore, the cooling assembly 202 also includes an upper connecting plate 102b that cooperates with the guide inclined plate 103a to form a stirring chamber 101a-1 with the rotating cavity 101a, and the stirring blade 202a is located in the stirring chamber 101a-1.
[0061] Furthermore, the cooling assembly 202 also includes a water inlet 103a-1 that penetrates the guide plate 103a and is symmetrical about the left and right positions of the first motor 104a.
[0062] Furthermore, the lower surface of the conical chisel head 201b is evenly distributed with chisel teeth, and the uniformly distributed cavity 201b-1 is evenly distributed with nozzles 201b-2 that penetrate the lower surface of the conical chisel head 201b.
[0063] It should be noted that the surfaces of the stirring blades, the first channel, the water inlet, the distribution chamber, the water inlet, and the nozzle are all coated with an anti-rust coating to prevent the inside of the device from rusting.
[0064] When in use, external water enters the mixing chamber through the inlet on one side, and the moisturizer enters the mixing chamber through the inlet on the other side. Then, the first motor is started, which drives the mixing blades to rotate through the drive shaft, so that the moisturizer and water are evenly mixed together. Then, the mixture passes through the inlet and the first channel into the distribution chamber, and is then evenly sprayed onto the concrete surface through the nozzle.
[0065] In summary, this invention enables water introduced into the mixing chamber to enter the uniform distribution chamber through the water inlet and then spray out from the nozzle of the conical chisel head. This achieves the simultaneous cooling of the conical chisel head and spraying of concrete, thereby increasing the service life of the conical chisel head and reducing dust. Furthermore, the mixing blades can evenly mix the introduced humectant into the cooled water, which is then sprayed onto the concrete by the nozzle. This protects the freshly roughened concrete in high-temperature and dry areas, ensuring the quality of the roughened concrete surface.

This embodiment provides a multi-purpose chiseling device that can simultaneously perform rotary chiseling and hammer chiseling on concrete to achieve a better chiseling effect. At the same time, it forms a beveled chiseling surface to reduce chiseling stress. While chiseling the concrete, water is sprayed to moisten the concrete to prevent dust from splashing. At the same time, it can also evenly mix the moisturizer into the water. Under the action of the centrifugal force of the rotating conical chisel head, it is evenly sprayed on the concrete surface, thereby achieving the function of moisturizing the newly chiseled concrete and cooling the conical chisel head.

[0080] The first motor 104a is mounted on the upper surface of the guide inclined plate 103a, and the drive shaft 104b is mounted on the first motor 104a. The drive shaft 104b passes through the guide inclined plate 103a and is fixedly connected to the connecting plate 102b. The drive shaft 104b and the guide inclined plate 103a are sealed by a rubber ring.
[0081] Furthermore, the cooling assembly 202 includes a stirring blade 202a, a first channel 201a-1 disposed inside the cross sliding shaft 201a and opening downward, a water inlet hole 201a-2 disposed at the upper end of the first channel 201a-1 and penetrating the surface of the cross sliding shaft 201a, and a uniformly distributed cavity 201b-1 disposed inside the conical chisel 201b and communicating with the first channel 201a-1;
[0082] The stirring blade 202a is mounted on the drive shaft 104b.
[0083] Furthermore, the cooling assembly 202 also includes an upper connecting plate 102b that cooperates with the guide inclined plate 103a to form a stirring chamber 101a-1 with the rotating cavity 101a, and the stirring blade 202a is located in the stirring chamber 101a-1.
[0084] Furthermore, the cooling assembly 202 also includes a water inlet 103a-1 that penetrates the guide plate 103a and is symmetrical about the left and right positions of the first motor 104a.
[0085] Furthermore, the lower surface of the conical chisel head 201b is evenly distributed with chisel teeth, and the uniformly distributed cavity 201b-1 is evenly distributed with nozzles 201b-2 that penetrate the lower surface of the conical chisel head 201b.
[0086] It should be noted that the spur gear, cross sliding shaft, guide slant plate, and semi-circular guide slider are all made of wear-resistant materials to improve service life. The surfaces of the stirring blade, first channel, water inlet, uniform distribution chamber, water inlet, and nozzle are all coated with anti-rust coating to prevent rust inside the device.
[0087] In use, the first motor is started, driving the connecting plate to rotate via the transmission shaft. Simultaneously, the spur gear mounted on the connecting plate rotates in a circular motion. The spur gear also meshes with the internal gear and rotates on its own axis. At the same time, the semi-circular guide slider, under the action of the return spring, is pressed tightly against the inclined surface of the guide plate. This causes the cross sliding shaft to move up and down with the undulation of the inclined surface and under the restriction of the cross sliding hole. This drives the conical chisel head to perform a circular motion while rotating and moving up and down, chiseling the concrete. At the same time, external water enters the mixing chamber through the water inlet on one side, and the moisturizer enters the mixing chamber through the water inlet on the other side. Then, the mixing blades rotate under the drive of the first motor, mixing the moisturizer and water evenly. The mixture then passes through the water inlet and the first channel into the distribution chamber, and is then evenly sprayed onto the concrete surface through the nozzle. This process also removes the heat generated when the conical chisel head roughens the ground, preventing the conical chisel head from overheating and affecting its service life.
[0088] In summary, the conical chisel head of this invention, through the combined action of the drive component, rotating component, and guide component, achieves both rotation and circular motion, while also moving up and down. This allows the chisel head to form an inclined cutting plane during operation, ensuring that the concrete is gradually roughened at an angle, reducing roughening stress and avoiding the problem of traditional roughening equipment creating stepped cutting marks on the concrete, requiring significant force from the worker to push the equipment forward. Simultaneously, the up-and-down movement of the chisel head also impacts the ground. It achieves simultaneous rotary chiseling and hammer chiseling for better chiseling results. At the same time, the water introduced into the mixing chamber can enter the uniform distribution chamber through the water inlet and then be sprayed out from the nozzle of the conical chisel head. This achieves the function of spraying concrete while cooling the conical chisel head, thereby improving the service life of the conical chisel head and reducing dust. Moreover, the mixing blades can evenly mix the introduced humectant into the cooling water, and then spray it onto the concrete through the nozzle. This protects the freshly chiseled concrete in high-temperature and dry areas and ensures the quality of the chiseled concrete surface.
