[0029] Example 1

[0030] like Figure 1-Figure 6 As shown:

[0031] A sealant scraping device is composed of a scraper assembly 1 and a collection box 2, and the scraper assembly 1 and the collection box 2 are connected in a detachable manner.

[0032] Specifically, the blade assembly 1 includes a blade holder 101, a main blade 102 and an auxiliary blade 103. The cross-section of the blade holder 101 is a square structure. The tail of the blade holder 101 is used for plugging and connecting with the collection box 2. The tail of the blade holder 101 is a gradually shrinking trapezoidal bin 104 structure. A rectangular connecting section 105 is integrally formed at the end of the trapezoidal bin 104. The rectangular connecting section 105 can be plugged and connected with the front end of the collection box 2.

[0033] Hollow side guard plates 106 are fixed to both sides of the front end of the blade holder 101, a middle transverse partition plate 107 is fixed horizontally between the two hollow side guard plates 106, and the main blade 102 is fixed to the front end of the middle transverse partition plate 107. The auxiliary blade 103 is fixed to the inner side of the front end of the two hollow side guard plates 106 and is located below the middle transverse partition plate 107.

[0034] In this embodiment, the distance between the two hollow side guard plates 106 is equal to or slightly larger than the thickness of the side wall of the gear box observation window 3, so that when the device is in use, the two hollow side guard plates 106 can be just stuck on the side wall of the gear box observation window 3, and at the same time, the middle cross partition 107 is located on the upper surface of the side wall of the observation window. At this time, the main scraper 102 is used to scrape the sealant on the side wall of the observation window, and at the same time, the auxiliary scraper 103 arranged inside the two hollow side guard plates 106 is used to scrape the sealant on the edge of the side wall of the observation window.

[0035] In this embodiment, the hollow side guard plates 106 on both sides of the front end of the tool holder 101 have a hollow structure inside, and the rear notch 108 of the hollow side guard plates 106 is connected to the inner side of the tool holder 101. During the scraping process, the sealant on both sides of the side walls of the observation window scraped by the auxiliary scraper 103 moves backward through the internal cavity of the hollow side guard plates 106. During the scraping process, the sealant is continuously pushed by the subsequent sealant, thereby entering the tool holder from the cavity of the hollow side guard plates 106, and is subsequently collected by the collection box 2.

[0036] In this embodiment, the main scraper 102 is mainly used to remove a large amount of sealant on the protruding edge of the gear box observation window; the auxiliary scraper 103 is mainly used to remove the sealant on the side edge of the gear box observation window.

[0037] The present invention scrapes away aged and dried sealant by the main scraper 102 and the auxiliary scraper 103, effectively avoiding the problem of sealant falling into the gear box. The spacing between the two auxiliary scrapers 103 allows the auxiliary scrapers 103 to fit well with the side wall of the gear box observation window 3, and the main scraper 102 can also fit with the upper surface of the side wall of the gear box observation window 3, ensuring the collection efficiency of the sealant.

[0038] Specifically, the collecting box 2 includes a box body 201 , a gradually shrinking trapezoidal connecting bin 202 is provided at the front end of the box body 201 , and a rectangular bin 203 for connecting to the rectangular connecting section 105 at the rear end of the knife holder 101 is provided at the front end of the trapezoidal connecting bin 202 .

[0039] In order to facilitate the connection between the knife holder 101 and the collection box 2, the inner side of the rectangular bin 203 of the collection box 2 matches the outer side of the rectangular connecting section 105 of the knife holder 101, so that the rectangular connecting section 102 can be inserted and fixed in the rectangular bin 203 of the collection box 2.

[0040] The rectangular bin 203 and the rectangular connecting section 105 have a certain length, so that the two can have a certain connection strength after being plugged and connected, so that the collection box can drive the knife seat to move together.

[0041] A sealant collection bag 4 is embedded in the interior of the rectangular bin 203, and a shaping steel ring 5 is provided at the open end of the sealant collection bag 4. The shaping steel ring 5 has a rectangular structure and can be placed in the interior of the rectangular bin 203, and a positioning step 204 is provided on the inner side of the rectangular bin 203. When the sealant collection bag 4 is placed in the collection box 2, the bag body is straightened and placed in the collection box 2, and the shaping steel ring 5 at the front end of the bag body is stuck in the positioning step 204 inside the rectangular bin 203. At this time, the rectangular connecting section 105 of the knife seat 101 is inserted into the rectangular bin 203 of the collection box 2, and the front end of the rectangular connecting section 105 is pressed against the positioning steel ring 5 to fix it.

[0042] The collecting box 2 is used to collect the sealant removed by the scraper assembly 1, and the sealant collecting bag 4 can be reused to prevent waste of resources. The sealant collecting bag 4 embedded in the collecting box 2 can better take out the collected sealant, solving the problem that the traditional sealant is difficult to handle after being collected in the box.

[0043] In this embodiment, a handle 205 is fixed on the top of the box body 201, and the handle 205 is used to facilitate holding and operating the collection box 2.

[0044] In this embodiment, the box body 201 of the collection box can be made of a transparent PVC board to facilitate observation of the internal sealant collection situation.

[0045] In order to allow the waste sealant removed by the scraper assembly to enter the collection box smoothly, an exhaust fan is provided at the rear of the collection box, which can exhaust air outward at the rear of the box body, forming a negative pressure inside the box body, thereby facilitating the waste sealant removed by the scraper assembly to be sucked into the collection box and stored in the sealant collection bag. A battery and a switch are provided at a suitable position on the box body, the battery provides power to the exhaust fan, and the switch controls the start and stop of the exhaust fan.

[0046] When the device of the present invention is in use, the collection box and the blade holder are assembled together, the handle is held, the two hollow side guard plates of the blade assembly are clamped on the protruding edge of the observation window of the gear box, and the main blade is aligned with the upper surface of the protruding edge. After confirming that the clamping is in place, the device is directly pushed to scrape away the waste sealant. The main blade scrapes away the sealant on the top of the protruding edge, and the auxiliary blade scrapes away the sealant on the side wall of the protruding edge, thereby improving work efficiency and effectively ensuring the safe and reliable operation of the unit.

[0047] The present invention effectively solves the problem of inconvenient removal of old sealant, ensures that the sealant will not fall into the gear box during the removal process, and ensures that the gear oil will not be affected and the gear box filter element will not be blocked. The device of the present invention is small in size, light in weight, and easy to carry. The waste sealant in the collection box is easy to handle, labor-saving, and fast, and can ensure that the sealant can be quickly removed after each inspection of the gear box.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
