[0002] As a commonly used cleaning equipment at present, the floor cleaning machine is widely used in cleaning work of public places such as stations, shopping malls and office places, and is a kind of efficient cleaning facility. The ball head scraper of the floor cleaning machine is an important part of the floor cleaning machine, which is mainly used for cleaning the ground and removing stains, and is widely used in cleaning work of various hard floors such as railway platforms and station buildings. It has the advantages of environmental protection, energy saving and high efficiency. With the vigorous development of the floor cleaning machine, the ball head scraper has been fully developed. For example, the ball head scraper structure at the tail of the ground cleaning machine disclosed in the Chinese patent network (publication number CN214073165U) shows that such scraper structure is provided with a ball head structure between the scraper connecting plate and the bottom plate connecting plate, which realizes the change of the position of the scraper when passing through different cleaning surfaces, and the cleaning is more complete. The deformation problem of the scraper is avoided, and the use cost is reduced.
[0003] However, the floor cleaning machine scraper structure adopted by the above-mentioned disclosed patent and the existing market still has some deficiencies. The existing form of scraper structure can change synchronously with the concave-convex change of the road surface, but the overall volume is large, the modular compactness is insufficient, the space occupied is more, and the adaptive assembly with the floor cleaning machine is limited. Therefore, the technical personnel in the field provide a ground cleaning machine tail scraper structure for railway station platform to solve the problems raised in the above background technology.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution for the tail scraper structure of a railway station platform floor cleaning machine: A tail scraper structure for a railway station platform floor cleaning machine includes a mounting plate 1, a tooling plate 2 below the mounting plate 1, and telescopic guide rods 4 extending through the mounting plate 1 in an opposing configuration on the tooling plate 2. A return spring 5 is sleeved on the telescopic guide rod 4, directly opposite the mounting plate 1 and the tooling plate 2. The mounting plate 1 has guide holes adapted to the telescopic guide rod 4. The combined elastic force of the telescopic guide rod 4 and the return spring 5 allows the telescopic guide rod 4 to extend and retract along the mounting plate 1, and also allows the return spring 5 to compress and return along the mounting plate 1. Therefore, when the scraper structure is not in use... The tooling plate 2 is raised upwards and close to the mounting plate 1, separating the scraper component 11 from the ground. At the same time, the return spring 5 is compressed, maintaining an elastic compression and reset state. When the scraper structure is used later, the compression and reset of the return spring 5 pushes the tooling plate 2 downwards, so that the scraper component 11 contacts the ground for scraping and cleaning. Due to the combination of the tooling plate 2 and the scraper component 11, and the combination of the return spring 5 and the telescopic guide rod 4, it maintains an elastic contact with the ground. When encountering uneven road surfaces, it can elastically extend and retract to adjust and reset itself, always maintaining close contact with the ground for cleaning. At the same time, it has good self-adjustment and anti-scratch characteristics, and stronger self-adaptability.
[0028] As a further technical solution in this embodiment, two sets of magnetic magnets 7 are provided on the tooling plates 2 near both ends of the mounting plate 1, and two sets of electromagnetic magnets 6 are provided at both ends of the mounting plate 1. When the electromagnetic magnets 6 are energized, they generate electromagnetic force to magnetically attract and lock with the magnetic magnets 7. The electromagnetic attraction between the electromagnetic magnets 6 and 7 is greater than the elastic compression force of the return spring 5 and the load pressure of the tooling plate 2. By utilizing the energization of the electromagnetic magnets 6 to generate electromagnetic attraction with the magnetic magnets 7, the elastic compression force of the return spring 5 and the load pressure of the tooling plate 2 are overcome, allowing the electromagnetic magnets 6 and 7 to magnetically attract and lock with each other. The magnet 7 magnetically engages and lifts the tooling plate 2, separating the scraper component 11 from the ground. This enables the scraper structure to be lifted when not in use. Subsequently, by de-energizing the electromagnetic magnet 6, the electromagnetic magnet 6 and the magnet 7 are demagnetized and opened / closed. Under the elastic restoring potential energy of the return spring 5, the tooling plate 2 and the scraper component 11 make close contact with the ground in an elastic manner, while maintaining good self-expansion and contraction adjustment characteristics. This makes the scraper cleaning more flexible, the overall structure more compact, the braking more efficient, and is more conducive to the adaptation and assembly of the cleaning machine.
[0029] Example 2
[0030] Please see Figures 1-6 As shown, this embodiment further explains Example 1. A negative pressure port 9 is connected through the middle of the frame of the mounting plate 1, and a negative pressure channel 14 is opened through the middle of the frame of the tooling plate 2. The negative pressure port 9 and the negative pressure channel 14 are connected by a telescopic hose 10. The telescopic hose 10 is made of corrugated hose material. Utilizing the corrugated telescopic characteristics of the telescopic hose 10, when the tooling plate 2 is raised close to the mounting plate 1, it retracts itself, and when the tooling plate 2 is lowered close to the ground, it stretches itself, always maintaining a conductive connection, so that the negative pressure port 9 and the negative pressure channel 14 always maintain negative pressure conduction.
[0031] Furthermore, a scraper component 11 is provided below the tooling plate 2. The scraper component 11 includes a front scraper 111 on one side of the tooling plate 2 and a rear scraper 112 on the other side of the tooling plate 2. A dirt accumulation chamber 13 that communicates with the negative pressure channel 14 is spaced between the front scraper 111 and the rear scraper 112. The dirt accumulated in the dirt accumulation chamber 13 formed by the internal space of the scraper component 11 is used to collect the dirt that has been scraped and cleaned. Under the negative pressure communication between the negative pressure port 9, the telescopic hose 10 and the negative pressure channel 14, a negative pressure suction state is formed to extract the dirt in the dirt accumulation chamber 13 and send the dirt to the wastewater tank of the floor scrubber.
[0032] It should be noted that the bottom of the front scraper 111 of the scraper component 11 is provided with a dirt collection groove so that the dirt is sucked into the dirt accumulation chamber 13 by negative pressure. The bottom of the rear scraper 112 of the scraper component 11 is a smooth structure to avoid dirt overflow.
[0033] Example 3
[0034] Please see Figure 1 , Figures 5-6 As shown in the figure, this embodiment further explains other embodiments. Both ends of the tooling plate 2 are provided with guide wheel components 8. The guide wheel component 8 includes a support plate 81. One end of the support plate 81 is provided with a rolling wheel 82, and the other end of the support plate 81 is provided with a driven wheel 83. Through the setting of the guide wheel component 8, the rolling wheel 82 can contact the ground and play an auxiliary support role for the scraper structure. The setting of the driven wheel 83 can play an anti-collision protection role and avoid the corners being scratched when the cleaning machine is moving.
[0035] In addition, a first limiting plate 12 for pressing the front scraper 111 is provided on one side of the tooling plate 2. The two ends of the first limiting plate 12 are screwed with positioning bolts 121 that are threadedly connected to the tooling plate 2. A second limiting plate 15 for pressing the rear scraper 112 is provided on the other side of the tooling plate 2. The second limiting plate 15 is divided into two sections, and the interface of the two sections is provided with a snap-fit buckle 151. By using the first limiting plate 12 to press and position the front scraper 111, the front scraper 111 can be easily disassembled and assembled by simply turning the positioning bolts 121. At the same time, by using the second limiting plate 15 to press and position the rear scraper 112, the rear scraper 112 can be easily disassembled and assembled by simply moving the snap-fit buckle 151. This makes the daily disassembly, cleaning and maintenance of the scraper component 11 simpler and more convenient.
[0036] Furthermore, the mounting plate 1 is provided with at least one set of mounting seats 3. By setting the scraper structure to a compact magnetic opening and closing state and utilizing its self-expanding adjustment capability, its overall volume is smaller than that of the traditional ball joint connection form, and its assembly compatibility with the cleaning machine is more flexible. The scraper structure can be integrated with the cleaning machine simply by using the mounting seats 3.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
