[0030] The present application starts the synchronous driving mechanism 4 to drive the extrusion mechanism 3 and the primer scraping mechanism 2 to move synchronously, and then starts the vacuum cleaner 5, the primer scraping mechanism 2 scrapes the epoxy floor paint, and then the vacuum cleaner 5 will suck the epoxy floor paint in the primer scraping mechanism 2 into the transition box 6 through the telescopic pipe 7, and at the same time, the extrusion mechanism 3 will squeeze the epoxy floor paint in the transition box 6 into blocks and input it into the dust box 101, so as to maximize the use of the internal space of the dust box 101. The user does not need to worry about the need to frequently clean the dust box 101 during the process of cleaning the epoxy floor paint, thereby improving the cleaning efficiency; when using the device, the primer scraping mechanism 2 is lowered to contact the ground. Since the telescopic pipe 7 is retractable, there will be no interference problem. When it is not needed, the primer scraping mechanism 2 is raised to prevent it from scratching the ground; before scraping the epoxy floor paint, it is necessary to spray alkaline liquid on the epoxy floor.

[0031] Reference Figure 2 The primer scraping mechanism 2 includes: a shell 201, a first scraper 202, a recovery roller 203 and a second scraper 204. The shell 201 is liftably arranged on one side of the vehicle body 1, and a first scraper 202 is arranged at the bottom thereof. The recovery roller 203 is coaxially rotatably arranged in the shell 201, and a plurality of second scrapers 204 capable of abutting against the inner wall of the scraper are coaxially arranged on the roller body. One side of the shell 201 is connected to the interior of the transition box 6 through a telescopic pipe 7, and the synchronous drive mechanism 4 can drive the recovery roller 203 to rotate.

[0032] The present application starts the synchronous drive mechanism 4 to drive the recovery roller 203 to rotate, so that the epoxy floor paint on the inner side of the first scraper 202 is scraped off into the shell 201 through the second scraper 204, and then the epoxy floor paint in the shell 201 is sucked into the transition box 6 through the vacuum cleaner 5.

[0033] Reference Figure 3 : The outer side of the second scraper 204 is elastically connected to an elastic block 20401 that can abut against the inner side of the first scraper 202.

[0034] Through this design, the present application ensures that even if the second scraper 204 or the inner side of the second scraper 204 is worn, the elastic block 20401 will abut against the outer side of the second scraper 204 due to its elastic connection with the outer side of the second scraper 204 through the elastic member.

The extrusion screw 301 is coaxially and rotatably arranged in the transition box 6. The heating component is arranged on the vehicle body 1 and can heat the inside of the transition box 6.

One side of the transition box 6 is connected to the inside of the dust box 101 through a pipe whose inner diameter is smaller than the inner diameter of the transition box 6.

[0036] The present application starts the heating component to further soften the epoxy floor paint inside the transition box 6, and the synchronous drive mechanism 4 drives the extrusion screw 301 and the recovery roller 203 to rotate synchronously to squeeze the epoxy floor paint inside the transition box 6 into the dust box 101. Since one side of the transition box 6 is connected to the inside of the dust box 101 through a pipe with an inner diameter smaller than the inner diameter of the transition box 6, the squeezed epoxy floor paint is compressed, thereby greatly improving the utilization rate of the dust box 101, thereby reducing the cleaning frequency of the dust box 101, and improving the cleaning efficiency of the epoxy floor paint.

[0037] Reference Figure 2 The synchronous drive mechanism 4 includes: a first drive motor 401, a drive wheel 402, a transmission wheel 403 and a synchronous belt 404.

The recovery roller 203 is coaxially provided with a drive wheel 402 at one end, and the extrusion screw 301 is coaxially provided with a transmission wheel 403 at one end. The opposite ends of the synchronous belt 404 are respectively sleeved on the drive wheel 402 and the transmission wheel 403.

[0038] In the present application, the first driving motor 401 is started to drive the recovery roller 203 and the driving wheel 402 to rotate synchronously, thereby driving the transmission wheel 403 and the extrusion screw 301 to rotate through the synchronous belt 404 .

[0040] The housing 201 of the present application can be lifted and lowered in the limiting slide groove 102 through the limiting slider 20101, and the driving component 103 is started to drive the housing 201 to be lifted and lowered stably to ensure that no deviation occurs.

[0041] Reference Figure 4 and Figure 5 The driving assembly 103 includes: a second driving motor 10301, a driving gear 10302, a transmission gear 10303 and a screw rod 10304.

[0043] A filter screen is provided at the connection point between the air inlet of the vacuum cleaner 5 and the interior of the transition box 6 .

[0044] The present application adopts such a design to prevent the vacuum cleaner 5 from directly sucking the epoxy floor paint into the interior of the vacuum cleaner 5 .

[0045] Reference Figure 3 : A push handle 104 is vertically arranged on the vehicle body 1.

[0046] The present application adopts such a design to facilitate the user to push the vehicle body 1 .

[0047] Reference Figure 3 : A handle 10101 is horizontally arranged on one side of the dust box 101.

[0048] The present application adopts such a design to facilitate the user to disassemble the dust box 101 .
