Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a milling machine. Background Art

[0002] A road milling machine scraper is a blade installed on a road milling machine. It is used to remove the old asphalt layer and other impurities from the road surface so that it can be repaved with new materials. The scraper generally consists of a high-speed rotating blade, a crank connecting the blade and the milling machine, and other components. During use, the scraper of the milling machine will move on the road surface to scrape off the old asphalt layer and debris.

[0003] Existing milling machine scrapers are generally integrated molding structures. When one of the scraper blades is damaged, the entire scraper needs to be replaced. On the one hand, a lot of replacement time is wasted, and on the other hand, it causes waste of materials. In addition, the discharge belt conveyor is heavy, and the milling machine only uses the hydraulic cylinder to pull the discharge belt conveyor. When it is not working, the discharge belt conveyor still remains in a tilted state, which can easily cause damage to the discharge belt conveyor or the hydraulic cylinder, affecting its service life. Therefore, those skilled in the art provide a milling machine to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a milling machine, which aims to improve the problem in the prior art that when the scraper blade is damaged, the entire scraper needs to be replaced, wasting a lot of replacement time.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The transmission mechanism that this sliding part is connected with this sliding part has the shape of a cam, and this cam is fixed on the support frame, and this cam is fixed on the support frame, and this cam is fixed on the support frame.

[0007] Through the above technical solution, by driving motor one, the output shaft of driving motor one can drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the synchronous wheel two to rotate. The synchronous wheel two rotates through the synchronous belt and synchronous wheel one, so that the synchronous wheel one drives the connecting shaft to rotate, and the connecting shaft drives the mounting plate to rotate, thereby realizing the rolling of the cutter head, which can crush the ground. If one of the cutter heads is severely worn after long-term use, or is damaged by hard objects during milling of the road surface, the cutter head needs to be replaced. When replacing the cutter head, you only need to find the damaged cutter head, and then unscrew its corresponding fixing bolt from the inside of the threaded groove and the socket, and then pull out the clip mounting block from the inside of the clip mounting slot, take out the new clip mounting block and cutter head, and insert the clip mounting block into the inside of the clip mounting slot, and finally screw the fixing bolts into the inside of the threaded groove and the socket one by one to complete the replacement of the clip mounting block and cutter head.

[0008] Furthermore, the retracting and unretracting assembly includes a first belt segment, which is arranged on the left side of the machine body, and the left side of the first belt segment is hinged to the second belt segment, the first belt segment and the second belt segment are internally rotatably connected to a roller, and the external transmission of the roller is connected to a conveyor belt, an electric push rod is fixedly provided on the left side of the upper part of the machine body, and the telescopic end of the electric push rod is fixedly connected to the upper part of the second belt segment, a second motor is provided inside the first belt segment, and the output end of the second motor is fixedly connected to a winding wheel, a steel cable is provided outside the winding wheel, and the right part of the steel cable is fixedly connected to the front part of the first belt segment on the rear side.

[0009] Through the above technical solution, the user starts the drive motor 2, and the output end of the motor 2 drives the winding wheel to rotate synchronously, the steel cable is gradually unwound and separated from the winding wheel, and the first belt segment rotates along the rotating connection with the second belt segment under the action of its own gravity. The first belt segment and the second belt segment have the same length. When the first belt segment and the second belt segment are both in a vertical state, the lower ends of the first belt segment and the second belt segment are in contact with the ground. At this time, most of the weight of the entire discharge is supported by the ground, and the force applied to the machine body is small, which is conducive to extending the service life and effectively reducing the length and height of the space occupied by the milling machine in the storage state.

[0010] Furthermore, the front and rear sides of the right portion of the machine body are fixedly connected with a cylinder, and the rear side of the lower portion of the machine body and the telescopic end of the cylinder are fixedly connected with a roller.

[0011] With the above technical solution, by setting a cylinder for lifting, the relative position between the machine body and the roller in the vertical direction can be adjusted.

[0012] Furthermore, the fixing bolt is threadedly connected to the inside of the thread groove.

[0013] With the above technical solution, the clamping mounting block and the cutter head can be replaced by fixing the bolts in the internal threaded connection of the thread groove.

[0014] Furthermore, the mounting block is slidably connected to the inside of the mounting groove.

[0015] According to the above technical solution, the damaged cutter head can be taken out and replaced by sliding the mounting block inside the mounting groove.

[0016] Furthermore, the outer portion of the second belt segment is rotatably connected to a connecting frame, and the connecting frame is fixedly connected to the right portion of the machine body.

[0018] Furthermore, the mounting plate is rotatably connected to the interior of the fixing frame.

[0019] Through the above technical solution, the mounting plate is rotated inside the fixed frame, so that the cutter head can be rolled and the ground can be crushed.

[0020] Furthermore, universal wheels are fixedly connected to the outsides of the first belt segment and the second belt segment.

[0021] According to the above technical solution, the first belt segment and the second belt segment are moved in coordination by providing a universal wheel.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the present invention, through the coordination among the motor 1, the synchronous wheel 2, the synchronous wheel 1, the machine body, the mounting slot, the mounting block, the jack and the tool holder, when the tool head is worn or damaged, the operator can quickly and easily replace it, thereby reducing maintenance time and improving the availability of the equipment.

[0024] 2. In the present invention, through the coordination among the first belt segment, the second belt segment, the roller, the winding wheel, the steel cable, the slider, the winding wheel and the universal wheel, the length and height of the space occupied by the device in the storage state can be effectively reduced, which helps to save space during storage or transportation and improves the portability and economy of the device.
