Epoxy terrace priming paint scraping device

Technical Field

The invention belongs to the technical field of scraping devices, and particularly relates to an epoxy floor primer scraping device.

Background

Along with the long-time use of original epoxy terrace priming paint, can appear droing, it is ageing, influence the condition of normal use such as fracture, epoxy terrace painting need renovate, and current epoxy terrace painting and former ground terrace painting material conflict, unable stack construction, so need strike off again specially, and adopt the manual work to strike off when striking off most epoxy terrace priming paints in the market and polish, not only inefficiency is polished unclean, can influence the quality that the later stage renovated again, influence pleasing to the eye, often can appear a large amount of dust and solid particle when the manual work strikes off and polish, extremely influence constructor's healthy. Therefore, we propose an epoxy floor primer scraping device.

The technical scheme of the floor primer scraping device also appears in the prior art, for example, a Chinese patent with the patent number of 201820061250X provides the epoxy floor primer scraping device which comprises a support and a bottom box, wherein the support is positioned at the upper end of the bottom box and is fixedly connected with the bottom box, a fixing plate and an alkaline liquid box are arranged at the upper end of the bottom box, the fixing plate is positioned on one side of the alkaline liquid box, and a first vertical beam and a second vertical beam are arranged at one end of the fixing plate. The utility model discloses a basicity liquid case that sets up, the pipeline, distributive pipe and shower nozzle, can utilize the corrosive action of alkali lye, make old coating film inflation soft, thereby recycle the scraper and get rid of old epoxy terrace priming paint, strike off efficiently, can effectually inhale into the dust storage incasement portion with the gray layer through the dust catcher and the pipeline that set up, dust and solid particle are to the harm of human body in the effectual reduction air, lift cylinder through setting up, carousel and sand abrasive disc, can polish when striking off epoxy terrace priming paint, it is unclean to have overcome general scraping device striking off terrace priming paint because certain reason strikes off, further improvement strikes off the quality.

But the scraping device among the prior art produces easily when utilizing the scraper to scrape off the priming paint and scrapes incomplete the condition, and the priming paint after scraping simultaneously also can't carry out effectual recovery to influence the quality of scraping off of terrace and the cleanliness after scraping off.

In view of the above, the invention provides an epoxy floor primer scraping device, which is characterized in that the structure of the scraping device is arranged, so that the scraped primer can be automatically and effectively collected, the floor is cleaner after the primer is scraped, the subsequent floor renovation is convenient, the primer is scraped by using a scraper, the scraping effect is more sufficient and comprehensive, the dead angle generated in the scraping process of the primer is reduced, and the scraping efficiency is higher.

Disclosure of Invention

In order to make up the defects of the prior art, the invention provides the epoxy floor primer scraping device, the scraped primer can be automatically and effectively collected through the structure of the scraping device, so that the floor is cleaner after the primer is scraped, the subsequent floor renovation is convenient, the primer is scraped by using the scraper, the scraping effect is more sufficient and comprehensive, the dead angle generated in the scraping process of the primer is reduced, and the scraping efficiency is higher.

The technical scheme adopted by the invention for solving the technical problems is as follows: an epoxy floor primer scraping device comprises a machine body; the scraper blade is arranged on one side of the machine body, an inclined scraping surface is arranged on one side, away from the machine body, of the scraper blade, an arc-shaped surface is arranged at the bottom end of the scraping surface, support plates are symmetrically connected to two sides, close to the scraper blade, of the machine body, a cylindrical transition box is fixedly connected between the two support plates, the diameter of the inner wall of the transition box is the same as that of the arc-shaped surface, meanwhile, the bottom end of the inner wall of the transition box is in contact alignment with the top end of the arc-shaped surface, a motor is installed on one side of each support plate, a rotating shaft is connected to the end portion of the motor, the other end of the rotating shaft penetrates through the middle portion of the end surface of the transition box and is connected with a rotating column, the rotating column is connected with the end surfaces on two sides of the transition box in a rotating manner, a group of arc-shaped plates, a material receiving box is arranged between the two supporting plates and corresponds to the material receiving port; when the scraping device works, the situation of incomplete scraping is easily caused when the scraping device in the prior art scrapes the primer by using the scraper, and meanwhile, the scraped primer cannot be effectively recovered, so that the scraping quality and the cleanness of the ground floor are influenced; when the scraping device is used, the machine body can drive the scraper blade point consisting of the bottom surface and the scraping surface of the scraper blade to scrape off the primer when the machine body moves, so that paint slag generated after the primer is scraped can fall into the arc-shaped surface along the scraping surface due to the advancing state of the machine body, meanwhile, the motor can drive the rotary column and the arc-shaped plates to rotate through the rotating shaft, so that the paint slag in the arc-shaped surface can be pushed along the inner wall of the transition box in the process of rotating the arc-shaped plate at the receiving port into the arc-shaped surface until the paint slag stored between the two adjacent arc-shaped plates and the transition box can move to the receiving port, and at the moment, the inner wall of the transition box does not block the paint slag any more, so that the paint slag is thrown into the receiving box under the action of the self gravity and the arc-shaped plates, the effect of automatically collecting the scraped primer is achieved, and the floor is cleaner after the primer, convenient follow-up renovating to the terrace utilizes the scraper blade to strike off the priming paint simultaneously, strike off the effect more fully and comprehensive, reduce the priming paint at the dead angle that strikes off the in-process and produce, it is higher to strike off efficiency simultaneously, and the arc can produce the negative pressure at the work position of scraper blade when the transition incasement portion rotates for the priming paint can be collected by effectual suction arcwall face after being scraped by the scraper blade, has strengthened the collection effect of scraping device to striking off back priming paint.
