Description

Technical Field

[0001] The utility model relates to the technical field of scrapers, in particular to a scraper assembly. Background Art

[0002] At present, the more common scraper components, such as Figure 6 As shown, it generally includes a scraper 13 and a frame 14 for fastening the scraper 13, wherein the scraper 13 is mostly made of a straight plate structure, and the whole is in a straight line. This type of scraper assembly is very simple in structure, and the whole is only composed of a scraper 13 and a frame 14. Although the shape is regular, it is relatively simple, and basically in a single straight line. Therefore, this type of scraper assembly is generally suitable for scraping a small amount of scraped objects, and the scraped objects are relatively evenly distributed on the wall to be scraped.

[0003] However, for some occasions where a large amount of scraped material flows in from the outer end of the scraper assembly and is easily accumulated at the outer end of the scraper assembly, the above-mentioned type of scraper assembly cannot meet the use requirements of the occasion. Therefore, how to design a scraper assembly suitable for the occasion is an urgent problem that technicians in the industry need to solve. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a scraper assembly with a new structure to solve the problem that the existing single straight scraper cannot effectively scrape away a large amount of scraped objects flowing into the outer end of the single scraper.

[0005] To this end, the utility model proposes a scraper assembly, including a rear long scraper, a front short scraper is arranged in front of the outer section of the rear long scraper, and the front short scraper and the rear long scraper are connected at an angle.

[0006] Preferably, the scraper assembly also includes a mounting frame, and the front short scraper and the rear long scraper are mounted and connected to the mounting frame, thereby the two scrapers are mounted and connected through the mounting frame so that the two scrapers are at an angle to form a combined scraper assembly with a short front and a long rear.

[0007] Preferably, the mounting frame includes a linear mounting frame and an arc-shaped mounting plate, one end of the mounting plate is connected to the waist of the mounting frame, the front short scraper is installed and connected to the outer end of the mounting frame, the waist of the rear long scraper is connected to the other end of the mounting plate, and the inner end of the rear long scraper is connected to the inner end of the mounting frame.

[0008] Preferably, the front short scraper and the rear long scraper are mounted on the mounting frame through the provided mounting holes and fasteners fitted to the mounting holes, and the fasteners are sleeved with springs acting on the corresponding scrapers to achieve elastic mounting of the scrapers on the mounting frame.

[0009] Preferably, the mounting frame includes a mounting base plate and a reinforcing plate connected at right angles, the outer end of the mounting base plate is provided with a circular hole for mounting and connecting the front short scraper, and the rear end of the mounting base plate is provided with an oblong hole for connecting the inner end of the rear long scraper.

[0010] Preferably, the other end of the mounting plate is provided with an oblong hole for mounting and connecting the waist of the rear long scraper plate.

[0011] Preferably, the front short scraper and the rear long scraper both include a scraper body and a connecting frame, the connecting frame includes a top connecting plate, and two clamping plates located below the top connecting plate and connected to the top connecting plate, and the top of the scraper body is embedded in the two clamping plates.

[0012] Preferably, the angle is greater than zero degree and less than or equal to ninety degrees.

[0013] Preferably, the angle is greater than or equal to 30 degrees and less than or equal to 60 degrees.

[0014] Compared with the prior art, the utility model sets a front short scraper and a rear long scraper to form an angle between the two, and the front short scraper is set in front of the outer section of the rear long scraper, thereby constructing a front and rear combined scraper assembly with one short and one long.

[0015] Therefore, when the front and rear combined scraper assembly is scraping, especially when performing circumferential rotation scraping, in the process of the material to be scraped flowing in from the outer end of the scraper assembly, the front short scraper is arranged in front of the outer section corresponding to the rear long scraper, so it can first contact the material to be scraped flowing in from the outer end, and then push the material to be scraped in front of the outer section of the rear long scraper in advance, so as to reduce the scraping task of the rear long scraper, so that the rear long scraper can better effectively scrape the material to be scraped in front of it and avoid the accumulation of the scraped material.

[0016] During the scraping process, the scraped material scraped by the front short scraper will naturally push the material to be scraped near the inner end of the scraper assembly when the scraper assembly performs rotational scraping, thereby allowing the scraped material to be gradually pushed from the outer end of the scraper assembly to the inner end of the scraper assembly. If a collecting hole is provided at the inner end, the scraped material will be merged into the collecting hole under the action of the scraper assembly to achieve overall scraping, thereby avoiding the problem in the prior art that the single linear scraper, especially during circumferential rotation scraping, causes the material to be scraped to accumulate at the outer section and cannot be effectively and quickly merged into the collecting hole.

[0025] The following will be combined with the accompanying drawings to clearly describe the technical solutions in the specific embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the following embodiments are within the scope of protection of the utility model.

[0026] In this embodiment, a scraper assembly is disclosed, which can be used for circumferential rotation scraping. The circumferential rotation scraping occasions can be understood as, for example, the rotary scraping stirring in a mixer, the rotary scraping dirt at the bottom of a sewage treatment device, etc.

[0027] In this embodiment, circumferential rotation scraping and a central collection hole are provided at the bottom to be scraped are used as an example for description. Figure 1-Figure 5 In this embodiment, a scraper assembly is disclosed, which includes a front short scraper 1, a rear long scraper 2 and a mounting frame 3. The front short scraper 1 is arranged in front of the outer section of the rear long scraper 2, and both scrapers are installed and connected to the mounting frame 3. After installation and connection, an angle is formed between the two scrapers, thereby constructing a scraper assembly with different lengths in front and back, and the two scrapers of the scraper assembly are not arranged in parallel, but are arranged at an angle. For the front short scraper, it does not have the same length as the rear long scraper 2, but is significantly shorter than the rear long scraper 2, and is arranged in front of the outer section of the rear long scraper 2.

[0028] It should be noted that the rear long scraper 2 is in a straight line shape, the short front scraper 1 is also in a straight line shape, and the rear long scraper 2 has an outer section, a middle section and a rear section connected in an integral structure.

[0029] It can be seen that when the scraper assembly of the above structure is scraping, especially when the material to be scraped is introduced from the outer end of the scraper assembly, the front short scraper 1 can share the scraping task of the rear long scraper 2, avoiding that all the material to be scraped is scraped by the rear long scraper 2, and under the scraping action of the front short scraper 1, the scraped material at the outer end can push the scraped material at the inner end, thereby driving all the scraped material to be scraped and introduced into the central collecting hole, avoiding the accumulation of scraped material at the outer end.

[0030] As for the specific structure of the front short scraper 1 and the rear long scraper 2, in this embodiment, the front short scraper 1 and the rear long scraper 2 both include a scraper body 4 and a connecting frame 5. The connecting frame 5 includes a top connecting plate 6, two clamping plates 7 located below the top connecting plate 6 and connected to the top connecting plate 6, and the top of the scraper body 4 is embedded in the two clamping plates 7. On the one hand, the scraper of this structure can firmly realize the reliable embedding of the corresponding scraper body through the two clamping plates, and at the same time, the corresponding scraper can be connected to the installation frame 3 through the top connecting plate 6. For details, please refer to Figure 1 , Figure 2 and Figure 3 .

[0031] As to how the front short scraper 1 and the rear long scraper 2 are installed and connected with the mounting frame 3, in this embodiment, the specific structure of the mounting frame 3 is firstly described in detail.

[0032] refer to Figure 1 , Figure 4 In this embodiment, the mounting frame 3 includes a straight mounting frame 8 and an arc-shaped mounting plate 9, one end of the mounting plate 9 is connected to the waist of the mounting frame 8, the front short scraper 1 is mounted and connected to the outer end of the mounting frame 8, the waist of the rear long scraper 2 is connected to the other end of the mounting plate 9, and the inner end of the rear long scraper 2 is connected to the inner end of the mounting frame 8. It should be noted that in this embodiment, in order to increase the strength of the mounting frame 3 and simplify the structure, the mounting frame 8 and the mounting plate 9 are an integrated structure. Thus, by setting the straight mounting frame 8 and the arc-shaped mounting plate 9, the effective installation of the front short scraper 1 and the rear long scraper 2 is achieved at the same time. In particular, by setting the arc-shaped mounting plate 9, an angle is formed between the front short scraper 1 and the rear long scraper 2 after installation and connection, so it can be adapted to the occasion of circumferential rotation scraping.

[0033] After installation and connection, in order to facilitate fine-tuning of the angle between the two scrapers to reach the desired set value, the mounting frame 8 includes a mounting base plate 10 and a reinforcing plate 11 connected at right angles, the outer end of the mounting base plate 10 is provided with a circular hole for mounting and connecting the front short scraper 1, and the rear end of the mounting base plate 10 is provided with an oblong hole for connecting the inner end of the rear long scraper 2. The other end of the mounting plate 9 is provided with an oblong hole for mounting and connecting the waist of the rear long scraper 2. It can be seen that the provision of the two oblong holes can achieve a slight adjustment of the installation position of the rear long scraper 2, thereby fine-tuning the distance between the two scrapers. It should be noted that the angle between the two scrapers is mainly determined by the arc-shaped mounting plate 9, and the fine-tuning of the installation angle between the two scrapers can be achieved by the provision of the two oblong holes.

[0034] It should be noted that the angle between the two scrapers is preferably greater than zero and less than or equal to 90 degrees. Of course, in this embodiment, 40 degrees between 30 degrees and 60 degrees is preferred. The main purpose is to avoid the angle being too large or too small so that the front short scraper 1 loses its function.

[0035] In actual operation, in order to prevent the two scrapers from hindering the normal rotation of the scraper assembly due to the presence of scraped objects between the scraper body 4 and the bottom to be scraped or the bottom to be scraped is not very smooth, the front short scraper 1 and the rear long scraper 2 are installed and connected to the mounting frame 3 through the provided mounting holes and the fasteners equipped in the mounting holes, and the fasteners are sleeved with springs 12 acting on the corresponding scrapers to realize the elastic installation of the scrapers on the mounting frame 3. It should be noted that the mounting holes can be understood as the above-mentioned round holes, oblong holes and through holes opened on the corresponding top connecting plates 6. Specifically, the fasteners can be a combination of fastening bolts and fastening nuts, the rod of the fastening bolts is arranged in the mounting holes, and the spring 12 is sleeved on the rod of the fastening bolts between the upper and lower mounting holes, and the upper and lower ends of the spring 12 are respectively pressed against the mounting frame 3 and the top connecting plate 6.

[0036] The scraper assembly of the utility model can effectively scrape the objects to be scraped by means of two scrapers of different lengths arranged at the front and the back. The front short scraper 1 can effectively reduce the scraping task of the rear long scraper 2, especially during circumferential scraping, which can prevent the accumulation of scraped objects.

[0037] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
