The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment, the scraper chip cleaner comprises a shell, a driving part and a chip removal assembly which is closed end to end, wherein the driving part is fixedly arranged on the shell and is in driving connection with the chip removal assembly; the chip removal assembly rotates between the tail of the shell and the chip removal port of the shell in a circulating mode and is used for conveying and discharging chips; the scraper chip cleaner further comprises a partition plate and a filtering assembly which are positioned in the chip removal assembly, the partition plate is fixedly connected with the shell and matched with the upper running track of the chip removal assembly, and chip removal channels are formed on the chip removal assembly, the upper surface of the partition plate and the bottom surface of the shell; the filtering component is fixedly connected with the shell and is positioned below the partition plate, and a water outlet is formed in the position, matched with the filtering component, of the shell.

A clapboard is arranged in a shell of the scraper chip cleaner to divide the chip removal assembly into an upper layer and a lower layer, and after a cutting fluid and chip mixture falls into the chip cleaner, chips are discharged along the clapboard by the chip removal assembly through a channel formed by the chip removal assembly and the clapboard; the cutting fluid flows into the bottom layer through the gap between the partition plate and the shell and is filtered by the filter assembly below the partition plate. According to the structure, the clearance formed by the chip removal assembly and the partition board is small, so that the phenomenon that long chips are wound on the scraper to cause chip removal blockage or deformation of the scraper can be avoided; the chips directly fall on the partition board, cutting fluid is left, and the chip removal assembly can be directly conveyed and discharged, so that the light chips are prevented from floating; and the filtering component at the bottom of the partition plate only needs to filter the liquid left from the partition plate, the cutting amount is less, and the cutting liquid can not be contacted with long chips, so that the filtering amount is reduced, the blockage of the filtering component is avoided, and the service life of the filtering component is prolonged.

Referring now to fig. 1-4, the design of the chip extractor blade is further understood by reference to the following description of the preferred embodiment, which includes a housing 10, a drive member, and a closed end-to-end chip removal assembly 20. Specifically, the higher end of the shell 10 is a head part provided with a chip removal port; the end facing away from the head is the tail. The driving member can be a speed reducing motor and is fixedly mounted on one side or the top of the housing 10. The output end of the speed reducing motor is in driving connection with the chip removal assembly 20. The speed reducer starts clockwise rotation, and the chip removal subassembly can circulate between the afterbody of casing and the chip removal mouth of casing and rotate, then discharges the transport of smear metal, because the chip removal mouth is higher than the afterbody, so the smear metal is carrying the waste that the carrying that the cutting can be reduced in the process of transport discharge and the process of dehydration in addition, also is convenient for the recovery processing of smear metal.

Further, the scraper chip ejector further comprises a baffle 30 and a filter assembly 40. The chip removal assembly is connected in the shell end to end for circulating operation, so that the chip removal assembly comprises an upper layer and a lower layer. The partition board is arranged between the two layers of conveying assemblies and is fixedly connected with the two inner sides of the shell. Welding or detachable connection may be used at this time. In order to achieve the best chip removal effect, the cross section of the partition plate on the side surface of the shell is matched with the upper-layer running track of the chip removal assembly. Namely, the shape of the clapboard is the same as the running track of the upper layer of the chip removal assembly, and the distance between the clapboard and the chip removal assembly is the same in the whole clapboard range. The filtering component is positioned below the partition plate and is fixedly connected with the two inner sides of the shell, and the shell is provided with a water outlet at the position corresponding to the filtering component. Therefore, the upper layer of the chip removal assembly and the upper surface of the partition plate form a chip removal channel; the lower layer of the chip removal component and the bottom surface of the shell also form a chip removal channel; a drainage channel is formed between the filter assembly and the shell. When the chip-liquid mixture falls into the scraper chip cleaner, chips directly fall on the partition plate and are conveyed to the chip removal port along the track of the partition plate through the chip removal assembly to be discharged; cutting fluid flows into the bottom of the shell through a gap between the partition plate and the shell, and is filtered by the filtering assembly when the liquid level is over the filtering assembly, so that clean liquid is discharged from the water outlet; a small amount of chips flowing into the bottom are conveyed to the partition plate through a chip removal channel formed by the chip removal assembly and the bottom of the shell, and then are discharged through a channel formed by the partition plate and the chip removal assembly. Therefore, a large amount of cuttings are directly conveyed and discharged by the partition plate, and the filter assembly cannot be blocked, damaged and the like; the clearance of chip removal subassembly and baffle is little, is not enough to make the long bits of long bits winding chip removal subassembly to the setting up of baffle makes the light direct of texture fall on the baffle, avoids floating the difficult exhaust problem.

The two ends of the scraper are fixed on the two conveying chains, and the extending end of the scraper facing one end of the partition board is intersected with the partition board (the extending direction of the chip removal surface of the scraper is intersected with the partition board). Optimally, the scraping plate is perpendicular to the partition plate, so that the structure is simplest, and the chip removal amount is maximum. The scraper blade can adopt any at least one of a flat plate, an L-shaped plate, a V-shaped plate or a wavy plate, and the like, as long as the chip removal function can be realized. Thus, on one hand, the connection is firm, and on the other hand, the structure of the scraper is simple, and the thickness can be relatively small.

In one embodiment, the scraper is provided with a plurality of water filtering gaps. Optimally, a certain distance is reserved between the water filtering gap and the upper surface and the lower surface of the scraper, namely the water filtering gap is arranged in the middle of the scraper. When the mixture of chips and liquid scraped from the bottom of the shell rotates clockwise and is lifted to the partition plate layer, the cutting liquid can flow out through the gap of the scraper plate, and the chips are remained on the scraper plate. Therefore, the water flowing speed can be increased, and the carrying of chips can be reduced.
