The construction of high-speed railways adheres to scientific and technological innovation and talent training, and applies a series of high-tech technologies, such as integrated independent technology and intelligent rail transportation, which greatly improves the speed and safety of high-speed rail trains, and also promotes the development of modern manufacturing and economic growth. The continuous improvement of the high-speed rail network and the continuous improvement of technology have made high-speed rail one of the important choices for people to travel. From 2009 to 2019, the average annual compound growth rate of China's high-speed rail passenger volume was about 42.9%, and its share of the total railway passenger volume increased from 3% to 64%, and reached 76% by 2022. The average annual compound growth rate of high-speed rail passenger turnover was about 42.1%, and the proportion increased from 2% to 53%, and even increased to 67% in 2022. In 2023, China's railway passenger volume will be about 3.85 billion, of which high-speed rail passenger volume will be about 2.94 billion, an increase of about 24% compared with 2019; the railway passenger turnover will be about 1,472.94 billion person-kilometers, of which high-speed rail passenger turnover will be about 982.19 billion person-kilometers, an increase of about 27% compared with 2019.

[0003] According to China State Railway Group Co., Ltd., in the first half of this year, the national railways transported a total of 2.096 billion passengers, with a passenger turnover of 777.952 billion person-kilometers, an increase of 2.1% and 2.3% year-on-year. The growth rates were 18.4% and 14.1%, both of which were record highs for the same period in history. It is expected that the growth rate of high-speed rail passenger volume will maintain at 15-20% in 2024. At present, my country's railway passenger volume and turnover are firmly ranked first in the world.

[0004] The history of China's high-speed rail development is a history of continuous innovation and struggle. In the future, with the continuous improvement and upgrading of the high-speed rail network, I believe that the development of China's high-speed rail will become more mature and perfect; the continuous improvement of the high-speed rail network and technological advancement will make high-speed rail an important choice for people's travel.

[0005] Due to the various natural needs of people during a long ride, domestic waste is an inevitable product. Vehicles are usually equipped with trash cans with garbage bags to store various garbage generated by passengers, such as skins, paper scraps, plastic packaging, etc.

The length of the garbage bag can be set to hold more than ten garbage blocks respectively, and the "compression-pushing-sealing-cutting" process is fully automatically controlled. Compared with the relatively single skills of existing new products, the automation level and comprehensive use have been greatly improved. Summary of the invention

[0013] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a new patented technology that can compress the stored garbage after collection and storage, push the compressed garbage into a garbage bag, and perform heat sealing and cutting on the bag. The technology can effectively reduce the volume of garbage and reduce pollution in an open environment, and at the same time can effectively reduce the number of manual removals and reduce labor intensity.

[0014] (II) Technical solution The present invention is achieved through the following technical solutions: A special equipment for garbage bins for motor vehicles, mainly comprising four parts: 1. a bin part consisting of a bin body and a lid which integrates storage and compression functions; 2. a device which is operated by a worm gear assembly and pushes the compressed garbage blocks in the bin body from the inside to the outside outlet through a push plate connected to the bin body; 3. a garbage bag and a garbage bag placement buckle part located around the outlet at the lower part of the bin body; 4. an electric heating double-channel sealing and cutting machine device arranged at the upper and lower edges of the outlet.

[0015] Automatic hot melt double-channel sealing, the function is to seal the bag mouth that has already been filled with garbage and the bottom of the unused part of the garbage bag, thus forming a sealed garbage bag body structure for the next use. While heat-sealing, the device is also designed with a cutting function between the two seals.

[0016] Preferably, a rotatable lid is provided at the upper end of the box body through a rotating shaft connection. An electric push rod mechanism is connected to the top surface of the lid. The size of the lid is designed to be hermetically matched with the four sides of the box body. At the same time, a guiding device is designed at the connection between one side of the box body and the lid to keep the lid in a horizontal state and move up and down.

[0017] Preferably, the compression stroke of the lid can run to a position flush with the inner surface of the upper edge of the box body outlet and stop automatically, temporarily remaining stationary. Thus, a volume cavity is formed together with the box body, which can keep the garbage block in a block shape and not easily disperse when the garbage block is pushed; after the horizontal push plate completes pushing the compressed garbage block out of the outlet, the cover plate starts to move upward to the initial open state at the top under the control of the control system.

[0018] Preferably, the worm and worm gear start to work through the push plate assembly connected in the box body after the pressing cover completes the compression action. Through the effective stroke design of the device, the push plate can completely push the garbage block out of the outlet and into the garbage bag located on the outlet at the bottom of the box body.

[0019] Preferably, the garbage bag is designed to be foldable and compressible. When the compressed garbage block is being pushed, the folded part is pulled open by a corresponding length, thus ensuring the process of filling the garbage. When there is no external force pulling, the un-stretched part remains in the folded state. When customizing, the stretching working length is considered to be sufficient for more than ten uses, so there is no need to replace and install a new garbage bag every time.

[0020] Preferably, outside the outlet of the garbage bin, a hot melt double-channel sealing machine device is provided. The outer seal relative to the box body is used to seal the bag filled with garbage, and the inner seal is used to seal the opening of the folded unused part of the garbage bag, thus forming the bottom of a new garbage bag. A cutting edge is provided between the two sealing devices, which can cut the continuous bag body from the middle part between the two seals.

[0021] Preferably, to achieve the coordinated consistency of the system operation, a special control program module is developed. The compression force is moderate and sufficient, and the stroke can ensure that the pressing cover stops automatically when it reaches the upper edge of the box body outlet. The device operates in an orderly manner according to the sequence of "compression - pushing - sealing and cutting - sealing return - push plate return - pressing cover return".

[0022] Preferably, the system is also provided with sensors and a stroke threshold warning function, which can prompt in time when a running fault occurs, facilitating the staff to discover and solve problems in time.

[0023] Preferably, the system operates with a 24V safety voltage, ensuring the safety performance of the device. For the mechanical components, low-noise equipment is selected, resulting in almost no noise pollution.

[0024] (III) Advantages The present invention provides a special device for a trash bin on a bullet train, having the following advantages: 1. The device realizes the storage of common domestic waste and the compression of normal inflatables, capable of reducing the volume occupation by nearly 70 - 80%. By setting multiple functions in one box, the garbage is compressed, and the compressed block is pushed into a garbage bag. Then, the bag is double-sealed and the connection of the bag is cut off, forming a full-cycle process without manual operation.

[0025] 2. The garbage bag is designed to be foldable and is provided with an installation bottom ring, which can be clamped on the buckle at the outlet to prevent it from being completely pulled out in a mess when taken out. According to the research on the use performance, the stretching length of the garbage bag can reach about 4.5 meters. Calculated according to the use length of about 38 cm for each package, it can be replaced once and used for more than ten times for packaging, effectively improving the efficiency and reducing the workload and labor intensity.

[0026] 3. After the compressed garbage block is put into the bag, the sealing machine device starts to work for double-channel hot melt sealing, which can seal the garbage part and also seal the bottom of the subsequent bag, forming a new sealed garbage bag body. A cutter is also designed between the two seals to cut the continuous plastic bag into individual pieces.

[0027] 4. The system operating voltage is selected as 24V DC safety voltage for power supply, which will not cause electric shock accidents. The whole process is set through programming, and each work operates in sequence. When a fault occurs, it can be prompted in time, with a high degree of automation and strong reliability and safety in device use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments.

[0029] Figure 1 It is a schematic diagram of the overall structure of a special device for a trash bin on a bullet train according to an embodiment of the present invention Figure 2 It is a schematic diagram of the pressing cover structure according to an embodiment of the present invention Figure 3 It is a schematic diagram of the pushing mechanism according to an embodiment of the present invention Figure 4 It is a schematic diagram of the heat-sealing structure design according to an embodiment of the present invention Figure 5 It is a schematic diagram of the structure design of the sealing and cutting working surface according to an embodiment of the present invention Figure 6Schematic diagram of the installation structure of the garbage bag in the embodiment of the present invention Detailed implementation manners

[0030] In combination with the attached drawings, for a special device for a high-speed train garbage bin of the present invention to achieve full-function automation, the electric push rod fixed on the push rod bracket pushes downward, and the movable pressing cover rotates along the rotatable shaft to the horizontal state. Then, under the combined action of the push rod and the guiding force, downward pressure is applied to compress the garbage already collected in the box into a block shape. The stroke stop position of the pressing cover is set at the inner edge level of the garbage block outlet. After the compression process is completed, according to the set program, the system worm gear push plate pushing mechanism starts to work. The worm gear drives the worm to rotate, thereby driving the pushing slider connected to the bottom inside of the box, and the garbage block can be horizontally pushed out of the garbage outlet. At this time, a folding garbage bag has been installed at the garbage bin outlet. The process of the garbage block being pushed out of the box is the process of entering the garbage bag. After this process is completed, the sealing and cutting mechanism starts to work, and the upper and lower sealing jaws close to complete the sealing and cutting actions of the garbage bag. A further description is made on the preferred mode of the technical solution Its static structure: As Figure 1 shown, a special device for a high-speed train garbage bin of the present invention mainly consists of a box body 1, a pressing cover 2, an electric push rod 3, an electric push rod bracket 4, a sealing device mechanism 5, a worm gear and worm pushing mechanism 6, a garbage bag 7 and other main parts

[0031] The support of the electric push rod is fixed on the bracket, and the bracket is connected to the outside of the garbage box body. The pressing cover is connected to the push arm of the electric push rod. The inner side of the pressing cover is designed with a horizontal step to ensure the horizontal state of the pressing cover by the mechanism. At the same time, the pressing cover is connected to the inner rear side wall of the box body through a hinge shaft and a fixed slider. In terms of the pushing mechanism, the power comes from the electric worm gear system. At the farthest distance from the worm gear, the pushing plate at the bottom of the box is connected through a connecting block. In the normal state, the pushing plate statically stops at the cavity position of the lowest groove in the box body, and the pushing surface of the pushing plate is flush with the inner wall surface of the box body when static, so it will not interfere with the process of garbage pressing down, and at the same time, it also plays a role in jointly forming a compression die cavity with the box body. The effective stroke of the pushing surface of the pushing plate is greater than the distance from this surface to the outer edge of the outlet, so it can ensure that the garbage block is completely pushed out

[0032] The sealing and cutting mechanism is installed at the upper and lower positions of the outlet. The power supply and control board are fixed on the outer vertical surface of the box body. The lower part of the sealing working port is horizontal with the lower part of the outlet. The upper sealing port is movable and compressible, and the fusion sealing process is completed when it contacts the lower jaw. The two contact surfaces of the seal are designed in the form of a double-channel sealing working surface. At the same time, a blade protruding in the middle of the two seals can cut the continuous garbage bag body. The garbage bag is professionally designed, including a rectangular base made of cardboard and a folded plastic garbage bag body. It is sleeved on the outlet position from the garbage bin outlet and is fixed by a buckle designed on the box body to fix the whole garbage bag. The folded part of the garbage bag has passed the tensile test and can expand synchronously with the length of the garbage block during the process of pushing the garbage block in without getting scattered. An entire garbage bag can hold more than a dozen garbage blocks, avoiding the problem of having to replace a new bag every time. The system also designs a management module to orderly control the operating conditions of each process. When a problem occurs, it has a fault prompt function to help detect and solve the fault in time.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
