[0012] Figure 1 A schematic structural diagram of a milling machine with a milling machine safety warning device according to the present application is shown.

[0013] Figure 2 A control logic schematic diagram of the safety warning device for a milling machine of the present application is shown. DETAILED DESCRIPTION

[0014] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0015] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0016] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0017] During the operation of the milling machine, due to the construction characteristics and equipment structure, the construction is usually carried out at night. The machine body is large in size and the construction environment is complex. There are also many various equipment (such as sweepers, cutters, sprinklers, etc.) around the machine for cooperation in the construction. Usually, the safety dispatch is carried out by the command personnel. There are inevitably certain safety risk factors, especially in the following situations: (1) Under special working conditions, the left or right side panel needs to be lifted during the operation. At this time, waste is likely to splash at the side panel, and it is easy to cause safety hazards when people get close to it; (2) The milling machine feed frame will swing left, right, up, and down according to the situation of the receiving vehicle. Ground staff often pass under the feeder. Because the feeder device uses a rotating feed belt to transport the milling materials during operation, it is easy to cause safety hazards when people pass under it.

[0018] Taking the above factors into consideration, the present application provides a milling machine safety warning device and a milling machine, which can form a warning fence around the equipment or in a specific working area, which can greatly improve the safety of the equipment construction site, especially the safety of nighttime construction.

[0019] Specifically, refer to Figure 1 and Figure 2In a first aspect, an embodiment of the present application provides a safety warning device for a milling machine, comprising a lighting device and a controller, wherein the lighting device comprises a plurality of side panel light-emitting elements 10, wherein the side panel light-emitting elements 10 are projection lamps or light strips, preferably projection lamps, and the side panel light-emitting elements 10 may be one or more. The plurality of side panel light-emitting elements 10 are installed on the fuselage 31 of the milling machine 30, for example, a projection lamp is installed at the middle position of each side of the fuselage 31, and a projection lamp is installed at the middle position of the rear side of the fuselage 31. In addition, the light-emitting end of the side panel light-emitting element 10 maintains a predetermined angle with the fuselage 31, so that when emitting light, a side panel warning light strip α can be formed on both sides and the rear side of the fuselage 31, especially at night and in dim light conditions, a relatively conspicuous light warning fence can be formed. In addition, the controller is connected to the electrical signal of the stroke sensor in the cylinder that controls the opening of the side panel 32 on the milling machine 30. , and is connected with the side panel light-emitting element 10 by electrical signals. In this way, after the milling machine 30 is started, when the controller recognizes the change of the stroke sensor in the cylinder, it indicates that the side panel 32 of the milling machine 30 is about to be opened or lifted. The controller controls the side panel light-emitting element 10 to emit light to form a side panel warning light belt on the left and right sides and the rear side of the fuselage 31, which can remind the surrounding personnel in a striking way not to approach, thereby preventing safety accidents caused by splashing materials at the side panel, making the operation of the milling machine 30 safer. The side panel light-emitting element 10 preferably emits red light, but of course it can also be light of other colors, which is not limited here.

[0020] In one embodiment, the lighting device further includes a material feeding light-emitting element 20, wherein the material feeding light-emitting element 20 is a projection lamp or a light strip, preferably a projection lamp, and the material feeding light-emitting element 20 can be one or more. The feed light emitting element 20 is installed on the feed frame 33 of the milling machine 30, and the light emitting end of the feed light emitting element 20 maintains a predetermined angle with the feed frame 33, so that when it emits light, a feed warning light strip β can be formed on both sides of the feed frame 33, which is particularly conspicuous at night and in dim light conditions. In addition, the controller is electrically connected to the control switch on the feed frame 33 and is electrically connected to the feed light emitting element 20. In this way, when the feed frame 33 starts to work, the controller recognizes that the feed frame 33 starts to transport waste by sensing the change of the control switch on the feed frame 33, and controls the feed light emitting element 20 to emit light to form a feed warning light strip 7 on both sides of the feed frame 33, which can remind surrounding personnel in a striking manner not to approach, thereby preventing the feed frame 33 from swinging up, down, left, or right to cause a safety accident, making the operation of the milling machine 30 safer.

[0021] It should be noted that since the feed light emitting element 20 is directly mounted on the feed rack 33, when the feed rack 33 swings left and right, the feed warning light strip β moves left and right accordingly, and when the feed rack 33 swings up and down, the illumination range of the feed warning light strip β also expands or shrinks accordingly. When it expands, it means that the feed rack 33 swings upward, and the danger level is higher at this time, and vice versa.

[0022] The second aspect of the embodiment of the present application also provides a milling machine 30, including a fuselage 31, a feed frame 33 and the milling machine safety warning device as described above, wherein the feed frame 33 is connected to the front end of the fuselage 31, wherein the lighting device is installed at the fuselage 31, or is installed at the fuselage 31 and on the feed frame 33 at the same time, wherein the beneficial effects of the milling machine safety warning device have been described in detail in the previous text, making the operation of the milling machine 30 safer, especially at night and in dim light conditions, which will not be repeated here.

[0023] It should be noted that the terms "first, second" in the present application are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0024] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
