Description

Technical Field

[0001] This utility model relates to the field of sintering machine guide trough technology, and in particular to a scraper structure for a sintering machine guide trough. Background Technology

[0002] In the sintering production process of the metallurgical industry, the feed chute is a key material guiding device between the sintering machine trolley and the single-roll crusher. The performance of its internal scraper structure directly affects the material transfer efficiency and equipment maintenance cycle. Existing scrapers mostly adopt a fixed metal scraper structure, fastened to the inner wall of the feed chute with bolts. Material guidance and cleaning of adhering material are achieved through the contact between the scraper blade and the trolley side plate. However, this structure suffers from uneven blade wear, unadjustable contact pressure, and difficulties in maintenance and replacement during long-term operation, leading to increased equipment downtime and affecting continuous production. Utility Model Content

[0003] The purpose of this utility model is to provide a scraper structure for the feed trough of a sintering machine, so as to solve the problems in the prior art where it is inconvenient to disassemble the scraper and the contact pressure is not easy to adjust, which leads to an increase in the frequency of equipment downtime, affects continuous production, and increases time costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a scraper structure for a sintering machine feed trough, comprising a feed guiding component and a scraping component, wherein the feed guiding component comprises a feed guiding sidewall and a feed guiding inner groove formed inside the feed guiding sidewall, wherein a first screw is provided inside the feed guiding sidewall, and one end of the first screw is connected to a transmission gear;

[0005] The scraping assembly includes a first connector and a connecting crossbar connected to the first connector, and a second connector is connected to one side of the connecting crossbar, and an mounting component is provided on the connecting crossbar.

[0006] Preferably, the first screw is provided on both sides of the guide sidewall, and the first screws provided on both sides move synchronously.

[0007] Preferably, the first connector includes a connecting post and a second threaded rod disposed inside the connecting post, wherein the connecting crossbar is connected to the second threaded rod and moves inside the connecting post.

[0008] Preferably, the second connector includes a mounting bracket and a first connecting seat connected to the lower side of the mounting bracket. A first scraper is connected to one side of the first connecting seat, and a first spring is connected to the other side of the first connecting seat. Second connecting seats are provided on both sides of the mounting bracket. A second scraper is connected to one side of the second connecting seat, and a second spring is connected to the other side of the second connecting seat.

[0009] Preferably, the mounting component includes a mounting ring and an adjusting ring mounted on the mounting ring. The mounting ring has a snap-fit ​​slider inside and a positioning post connected to the inner side of the mounting ring. A limiting displacement block is fixedly connected to one side of the snap-fit ​​slider, and a third spring is fixedly connected to the limiting displacement block.

[0010] Preferably, one end of the positioning post is fixedly connected to the mounting bracket, and the other end of the positioning post is provided with a circumferential tangent.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a first screw inside the guide sidewall, the first screw is driven to rotate by the transmission gear, and the connection between the first screw and the scraping component is used to drive the scraping component to move inside the guide inner groove. This allows the second connecting piece to move back and forth inside the guide inner groove, improving the scraping effect of the second connecting piece on the inner wall of the guide inner groove and ensuring that no material residue appears inside the guide inner groove.

[0013] 2. With the second connector, the first scraper and the second scraper are respectively mounted on the mounting bracket via the first connecting seat and the second connecting seat. A first spring and a second spring are respectively connected to one side of the first connecting seat and the second connecting seat, which can buffer the first scraper and the second scraper and prevent the first scraper and the second scraper from being easily damaged due to excessive pressure.

[0014] 3. The second connector is quickly installed and removed by the installation component. The positioning post is fixed on the mounting bracket. The positioning post is inserted into the inside of the mounting ring. Then, the adjusting ring is rotated. The positioning post is fixed in position by the squeezing of the locking slider by the adjusting ring. The positioning post can be removed by releasing the adjusting ring. No additional tools are required, making the operation simpler and faster. Attached Figure Description
