Description

Technical Field

[0001] This utility model relates to the field of highway maintenance equipment technology, and in particular to a crack repair device for highway construction. Background Technology

[0002] With the rapid development of highway transportation, road maintenance has become increasingly important. Road surface cracks are one of the common road defects. If not treated in time, they will seriously affect driving safety and the service life of the road. At present, special crack repair devices are usually used to repair road cracks. These devices generally include a heating box for heating and melting repair materials such as asphalt, and a mixing mechanism for mixing the materials.

[0003] However, in actual use, the existing mixing mechanism is often relatively simple in structure. When dealing with repair materials with high viscosity, the simple mixing method is difficult to achieve comprehensive and uniform stirring of the materials in the heating box. It is easy to create stirring dead corners in corners or local areas, resulting in uneven heating of the materials and the phenomenon of local solidification and clumping, i.e. "glue flowers". This insufficient stirring will seriously affect the fluidity of the materials, making the subsequent discharge and filling operation not smooth, and ultimately reducing the quality of crack repair.

[0004] Furthermore, to ensure good adhesion between the repair material and the road surface, the cracks must be thoroughly cleaned before filling. Many existing repair devices are single-function and lack road cleaning capabilities, requiring workers to carry additional cleaning equipment such as blowers or perform manual cleaning. This separation of procedures not only increases the labor intensity and equipment burden on workers but also reduces the overall continuity and efficiency of the construction process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a crack repair device for highway construction, which aims to improve the problems of uneven mixing of repair materials, easy clumping, and poor fluidity in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The mixing assembly includes a fixed cylinder driven to rotate by a first motor, with threaded blades fixed on the outer wall of the fixed cylinder, and rotating bars connected to both ends of the fixed cylinder via connecting rods, the rotating bars rotating synchronously with the fixed cylinder.

[0008] Preferably, the stirring assembly further includes a connecting column and a rotating shaft; the rotating shaft is fixed to the inner wall of the heating box, and the first motor drives the connecting column to rotate around the rotating shaft, thereby driving the fixed cylinder to rotate.

[0009] Preferably, it also includes a flow box and a discharge pipe, wherein the flow box is connected to the interior of the heating box, and the discharge pipe is connected to the flow box.

[0010] Preferably, it also includes a second motor and a rotary paddle; the rotary paddle is rotatably disposed inside the flow box and driven by the second motor to push the material from the flow box to the discharge pipe.

[0011] Preferably, it further includes an extension body disposed at the outlet end of the discharge pipe.

[0012] Preferably, it also includes a cleaning component; the cleaning component is installed on the base and includes a blower, an air duct communicating with the air outlet of the blower, and a nozzle disposed at the end of the air duct.

[0013] Preferably, the cleaning assembly further includes a connector for mounting the blower and a fixing plate connected between the blower and the duct.

[0014] Preferably, the system further includes a chassis and a storage box, wherein the chassis is fixed to the top of the base and the storage box is disposed on the top of the chassis.

[0028] The stirring assembly 2 includes a first motor 201, a fixed cylinder 202, a threaded blade 203, a rotating bar 204, a connecting rod 205, a connecting column 206, and a rotating shaft 207. The rotating shaft 207 is fixedly connected to the inner wall of the heating box 5. The first motor 201 drives the connecting column 206 to rotate. The connecting column 206 is sleeved on the rotating shaft 207 and drives the fixed cylinder 202 to rotate. The threaded blade 203 is fixedly connected to the outer wall of the fixed cylinder 202. The connecting rod 205 is connected to both ends of the fixed cylinder 202. The rotating bar 204 is connected and fixed between the connecting rods 205. When the fixed cylinder 202 rotates, the threaded blade 203 on its outer side and the rotating bar 204 driven by the connecting rod 205 rotate synchronously. This composite double stirring structure can fully and thoroughly stir the material in the heating box 5 without dead angles, effectively preventing the material from clumping due to static standing, thereby ensuring that the material always has good fluidity.

[0029] The road construction crack repair device also includes a flow box 10, a discharge pipe 12, a second motor 9, a rotating paddle 13, and an extension body 11; the flow box 10 is connected to the interior of the heating box 5, and the discharge pipe 12 is connected to the flow box 10; the second motor 9 is installed on the outside of the flow box 10, the rotating paddle 13 is rotatably disposed inside the flow box 10 and is drivenly connected to the output shaft of the second motor 9; the extension body 11 is fixedly connected to the outlet end of the discharge pipe 12.

[0030] The road construction crack repair device also includes a cleaning assembly 3 installed on the base 1; the cleaning assembly 3 includes a blower 301, a connector 302, a fixing plate 303, an air duct 304, and a nozzle 305; the connector 302 is used to fix the blower 301 to the base 1; the fixing plate 303 is connected between the blower 301 and the air duct 304 and fixed to the base 1; the nozzle 305 is fixedly connected to the outlet end of the air duct 304.

[0031] The road construction crack repair device also includes a housing 6 and a storage box 4; the housing 6 is fixedly connected to the top of the base 1; the storage box 4 is located on the top of the housing 6.

[0033] Working principle: Before crack filling, the operator starts the cleaning component 3 through the control panel 8. The blower 301 fixed on the connector 302 starts to work. The generated air enters the fixed plate 303 and is sprayed out at high speed from the nozzle 305 through the air duct 304, which blows away the dust and debris in the road crack.

[0034] During operation, the casing 6 supplies power to the heating box 5 to heat the repair material inside. At the same time, the first motor 201 is started. The first motor 201 drives the connecting column 206 to rotate around the rotating shaft 207 fixed to the inner wall of the heating box 5, which in turn drives the fixed cylinder 202 to rotate. During the rotation of the fixed cylinder 202, the threaded blades 203 on its outer side perform preliminary stirring of the material. At the same time, the connecting rods 205 at both ends of the fixed cylinder 202 drive the rotating bar 204 to rotate, further strengthening the stirring of the material stirred by the threaded blades 203. Through this synergistic effect of the threaded blades 203 and the rotating bar 204, this utility model realizes a dual composite stirring of the material, effectively solving the problem of material clumping and poor fluidity caused by insufficient stirring in the prior art.

[0035] After the material is fully heated and stirred, the second motor 9 is started. The second motor 9 drives the rotating paddle 13 in the flow box 10 to rotate, actively pushing the material into the discharge pipe 12. The material is finally precisely filled into the crack through the extension 11 at the end of the discharge pipe 12.
