Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, and in particular to a milling machine with a clutch function. Background Technology

[0002] Milling machines are one of the main types of machinery used in asphalt pavement maintenance and construction, and one of the main pieces of equipment used in asphalt concrete pavement maintenance and construction. They are mainly used for excavation and renovation of asphalt concrete pavement in highways, urban roads, airports, freight yards, etc. They can also be used to remove defects such as road surface bumps, oil waves, textures, and ruts. In addition, they can be used to excavate road potholes and trenches, as well as to roughen cement pavement and mill and level surface misalignments.

[0003] The crushing roller of a milling machine rotates at high speed during operation to mill the road surface. However, when the milling machine is paused midway, the crushing roller needs to stop rotating. Currently, most milling machines use a clutch to control the rotation and stopping of the crushing roller. However, the clutch of a milling machine generally uses a wet friction plate clutch or a dry friction plate clutch, but its structure is relatively complex, the manufacturing cost is high, maintenance is inconvenient, and the operation requires a high level of skill from the operator, which leads to prolonged troubleshooting time and affects the construction progress of the project. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a milling machine with a clutch function.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A milling machine with a clutch function includes a machine body, on which a power component and a crushing roller are disposed. A clutch assembly is disposed between the power component and the crushing roller. The clutch assembly includes a driving wheel and a driven wheel rotatably disposed on the machine body. The driving wheel is drivenly connected to the power component, and the driven wheel is drivenly connected to the crushing roller. A rocker arm is rotatably disposed on the machine body, and a tensioning wheel is rotatably disposed on the rocker arm. The tensioning wheel is located between the driving wheel and the driven wheel. A belt is wound around the driving wheel, the driven wheel, and the tensioning wheel.

[0007] Preferably, the rocker arm is provided with a straightening rod, the straightening rod is located on one side of the tensioning wheel, and the belt is located between the straightening rod and the tensioning wheel.

[0008] Preferably, the machine body is provided with a rotating shaft, the rocker arm is rotatably mounted on the rotating shaft, and the rotating shaft is located in the middle of the rocker arm.

[0009] Preferably, the machine body is provided with a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the rocker arm.

[0010] Preferably, the piston rod of the hydraulic cylinder is provided with a connecting rod, and the rocker arm is provided with a pin on the side away from the tension wheel, and the pin is connected to the connecting rod.

[0011] Preferably, the pin is slidably mounted on the connecting rod, a fastening nut is provided at the end of the connecting rod away from the hydraulic cylinder, and a spring is sleeved on the connecting rod, with the spring located between the pin and the fastening nut.

[0012] Preferably, the driving pulley, driven pulley, and tensioner pulley are all multi-groove pulleys.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] 1. In this utility model, the power component drives the drive wheel to rotate, and a belt is wound between the drive wheel and the driven wheel. Therefore, the driven wheel can be driven to rotate through the belt transmission, thereby driving the crushing roller to rotate and mill the ground. The tensioning wheel can tighten the belt and prevent it from slipping. When the work is stopped, simply rotate the rocker arm to separate the tensioning wheel from the belt. After the belt loosens, it can no longer transmit power, and the driven wheel and the crushing roller stop rotating. Conversely, the rocker arm rotates in the opposite direction to make the tensioning wheel engage with the belt, tightening the belt and allowing the crushing roller to continue rotating. Therefore, the clutch assembly in this utility model has a simple structure, can control the rotation and stop of the crushing roller, and is easy to maintain and repair, requiring less skill from the operator.

[0015] 2. In this utility model, a straightening rod is provided on the rocker arm. When the milling machine stops working, the rocker arm rotates to separate the tension wheel and the belt. At the same time, the straightening rod contacts the belt and drives the belt to quickly separate from the driving wheel and the driven wheel, shortening the response time of the crushing roller stopping rotation.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 3 As shown, a milling machine with a clutch function includes a machine body 1, on which a power component 2 and a crushing roller 3 are mounted. The power component 2 is fixedly mounted on the upper part of the machine body 1, and the crushing roller 3 is rotatably mounted on the lower part of the machine body 1 for milling the road surface. A clutch assembly is provided between the power component 2 and the crushing roller 3. The clutch assembly includes a drive wheel 4 and a driven wheel 5 rotatably mounted on the machine body 1. The drive wheel 4 is drivenly connected to the power component 2, and the driven wheel 5 is drivenly connected to the crushing roller 3. A rocker arm 6 is rotatably mounted on the machine body 1, and a tensioning wheel 7 is rotatably mounted on the rocker arm 6. The tensioning wheel 7 is located between the drive wheel 4 and the driven wheel 5 and is located at the lower part of the rocker arm 6. A belt 8, which is a V-belt, is wound around the drive wheel 4, the driven wheel 5, and the tensioning wheel 7.

[0024] In this invention, rotating the rocker arm 6 causes the tensioning wheel 7 to contact or separate from the belt 8, thereby tightening or loosening the belt 8 and causing the crushing roller 3 to rotate or stop. Specifically, when the crushing roller 3 needs to rotate to mill the road surface, rotating the rocker arm 6 causes the tensioning wheel 7 to contact the belt 8, putting the belt 8 in a tightened state. The output end of the power component 2 is connected to the drive wheel 4, so the power component 2 can drive the drive wheel 4 to rotate. Through the transmission of the belt 8, the driven wheel 5 can rotate. The driven wheel 5 is connected to the crushing roller 3, so the driven wheel 5 can drive the crushing roller 3 to rotate, thereby milling the road surface. Conversely, when... The crushing roller 3 needs to stop rotating to put the milling machine into standby mode, thereby reducing the output power of the power component 2 and saving energy. The rocker arm 6 rotates in the opposite direction, causing the tensioner 7 to separate from the belt 8. The belt 8 is then in a slack state, preventing the belt 8 from transmitting power between the drive wheel 4 and the driven wheel 5. Consequently, the power of the drive wheel 4 cannot be transmitted to the driven wheel 5, so the driven wheel 5 stops rotating, causing the crushing roller 3 to stop rotating, and the milling machine to be in standby mode. In this utility model, the clutch assembly has a simple structure, which facilitates the maintenance of the equipment, requires less skill from the operator, and makes maintenance faster, thus reducing the impact on the construction progress.

[0025] It should be noted that the power component 2 can be a motor or an engine. In this embodiment, the power component 2 is an engine. The output shaft of the engine is fixedly connected to the drive wheel 4. Therefore, after the engine starts, it can drive the drive wheel 4 to rotate, thereby realizing the output of power.

[0026] Furthermore, a straightening rod 9 is provided on the rocker arm 6. The straightening rod 9 is fixedly installed at the lower part of the rocker arm 6 and is located on one side of the tensioning wheel 7. A gap is left between the straightening rod 9 and the tensioning wheel 7, and the belt 8 is located between the straightening rod 9 and the tensioning wheel 7. In this embodiment, when the crushing roller 3 needs to stop rotating, the rocker arm 6 is rotated to move the straightening rod 9 closer to the belt 8. During the rotation of the rocker arm 6, the tensioning wheel 7 separates from the belt 8, causing the belt 8 to loosen. At the same time, the belt 8 comes into contact with the straightening rod 9. Since the belt 8 is a V-shaped belt and is used in large equipment such as milling machines, the belt 8 has a certain degree of rigidity. Therefore, after the straightening rod 9 comes into contact with the belt 8, it can push the belt 8, causing the belt 8 to quickly separate from the driving wheel 4 and the driven wheel 5, so that the crushing roller 3 can stop rotating quickly and avoid the belt 8 being in a semi-clutch state, which would cause the crushing roller 3 to continue rotating.

[0027] Furthermore, a rotating shaft 10 is fixedly installed on the machine body 1, and a rocker arm 6 is rotatably mounted on the rotating shaft 10. The rotating shaft 10 is located in the middle of the rocker arm 6. During the rotation process, the rocker arm 6 rotates around the rotating shaft 10 as the center, thereby achieving the tensioning and relaxation of the belt 8.

[0028] Furthermore, a hydraulic cylinder 11 is provided on the machine body 1. The cylinder barrel of the hydraulic cylinder 11 is hinged to the machine body 1, and the piston rod of the hydraulic cylinder 11 is connected to the upper end of the rocker arm 6. The extension and retraction of the piston rod of the hydraulic cylinder 11 causes the rocker arm 6 to rotate on the machine body 1, thereby tightening and loosening the belt 8.

[0029] In another embodiment, a connecting rod 12 is fixedly provided at the front end of the piston rod of the hydraulic cylinder 11. The connecting rod 12 is collinear with the piston rod of the hydraulic cylinder 11. A pin 13 is rotatably provided on the side of the rocker arm 6 away from the tension wheel 7. The pin 13 is connected to the connecting rod 12. A through hole is provided on the pin 13. The connecting rod 12 is slidably disposed in the through hole of the pin 13. A fastening nut 14 is threaded on the end of the connecting rod 12 away from the hydraulic cylinder 11. A spring 15 is sleeved on the connecting rod 12. The spring 15 is located between the pin 13 and the fastening nut 14. The spring 15 has a certain buffering function and can play a role in buffering and shock absorption. In this embodiment, when the belt 8 needs to be tightened, the piston rod of the hydraulic cylinder 11 retracts, and the connecting rod 12 slides to one side of the hydraulic cylinder 11, causing the rocker arm 6 to rotate clockwise. At the same time, it can compress the spring 15. During the rotation of the rocker arm 6, the tensioning wheel 7 contacts the belt 8, causing the belt 8 to tighten. Conversely, when the crushing roller 3 needs to stop rotating, the piston rod of the hydraulic cylinder 11 extends, causing the connecting rod 12 to slide away from the hydraulic cylinder 11. The rocker arm 6 then rotates counterclockwise, causing the belt 8 to loosen. At the same time, the straightening rod 9 pushes the belt 8 to quickly separate from the driving wheel 4 and the driven wheel 5. The power output from the power component 2 cannot be transmitted through the belt 8, so the crushing roller 3 can quickly stop rotating.

[0030] Furthermore, the driving pulley 4, driven pulley 5, and tensioner 7 are all multi-groove pulleys, and to match them, multiple belts 8 are provided, each belt 8 is set in a corresponding groove, making the transmission more stable.

[0031] Furthermore, a reducer is provided between the crushing roller 3 and the driven wheel 5. The driven wheel 5 is fixedly connected to the input shaft of the reducer, and the crushing roller 3 is fixedly connected to the output shaft of the reducer. The input shaft and output shaft of the reducer are arranged perpendicularly. Therefore, when the driven wheel 5 rotates, it transmits power to the crushing roller 3 through the reducer, causing the crushing roller 3 to rotate. At the same time, the reducer can reduce the speed and increase the output torque, enabling the crushing roller 3 to mill the road surface.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
