The specific embodiment
The utility model embodiment provides a kind of scraper of trommel mixer, has reduced difficulty of processing.
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to accompanying drawing 1-3, the scraper of the trommel mixer that the utility model embodiment provides comprises rabble arm 1 and the drag head 2 that is arranged on rabble arm 1 one end, and drag head 2 is weldingly connected with rabble arm 1.The scraper of this trommel mixer adopts split-type structural, drag head 2 and rabble arm 1 welding, consists of.While processing above-mentioned scraper, cast out first respectively drag head 2 and rabble arm 1, then drag head 2 and rabble arm 1 are carried out respectively to fine finishining, finally control both relative connection angle well both are welded together.Because scraper of the present utility model is adding man-hour, cast separately respectively drag head 2 and rabble arm 1, be convenient to the die sinking of casting; Meanwhile, when being carried out to fine finishining, drag head 2 and rabble arm 1 can not impact, and be convenient to each other both connected positions of fine finishining; So the utility model has reduced the difficulty of processing of scraper.
In addition, when the utility model difference fine finishining drag head 2 and rabble arm 1, be convenient to controlled working precision, can control well the precision of scraper by controlling the connection angle of drag head 2 and rabble arm 1 simultaneously, and then be applicable to well the situation of production.
Preferably, in a kind of specific embodiment of the utility model, on drag head 2, offer the first groove, on rabble arm 1, offer the second groove 11, between drag head 2 and rabble arm 1, by being filled in respectively the welding rod 3 of the first groove and the second groove 11, be weldingly connected.On drag head 2 and rabble arm 1, offer respectively the first groove and the second groove 11 for welding, can guarantee welding quality, and then guarantee the bonding strength of drag head 2 and rabble arm 1.
Further, in the scraper that above-described embodiment provides, welding rod 3 is preferably cast tungsten carbide gas welding rod.Cast tungsten carbide gas welding rod has higher wearability and resistance to impact, can improve the bonding strength of drag head 2 and rabble arm 1, has improved the service life of scraper.Certainly, above-mentioned drag head 2 and rabble arm 1 can also adopt other welding rods that can reach weld strength to weld.
In order to guarantee welding quality, the first groove and the second groove 11 are all preferably miter angle groove.Now, the first groove forms by two relative inclined-planes with certain angle with the second groove 11, and in the present embodiment, the angle on two inclined-planes is 45 degree, and the groove welding quality of 45 degree is better; Certainly, above-mentioned the first groove and the second groove 11 can also be other number of degrees, as 30 degree or 60 degree etc.; Meanwhile, above-mentioned groove is not limited to by inclined-plane and forms, and can also consist of curved surface, and the utility model is not done concrete restriction to this.
In the scraper that above-described embodiment provides, the width of the first groove and the second groove 11 is 12mm.According to the actual size of different use occasions and drag head 2, rabble arm 1, the width of the first groove and the second groove 11 can also be selected other numerical value, as 11mm-16mm etc.
In a kind of specific embodiment of the utility model, on the surface of drag head 2 and the surface of rabble arm 1 near one end of drag head 2, be provided with wearing layer 4, improved the wearability of scraper, extended scraper service life.Fill as shown in Figure 1 figuratum position and be wearing layer 4 of the present utility model.
For wearing layer is combined better with drag head 2 and rabble arm 1, in above-described embodiment, the surface of drag head 2 and rabble arm 1 are near all offering a plurality of spaced installing holes on the surface of one end of drag head 2, and wearing layer 4 is laminated in installing hole.Because installing hole covers wearing layer 4 inner sides, so attached not shown installing hole.Part wearing layer 4 is laminated to the interior surface of drag head 2 and rabble arm 1 like this, has improved bond strength, has reduced coming off of wearing layer 4.
In order further to optimize technique scheme, the thickness that the wearing layer 4 of above-mentioned scraper protrudes drag head 2 and rabble arm 1 surface is preferably 8mm, the thickness that is wearing layer is 8mm, can guarantee in wearability, to avoid the too thick problem that causes cost to increase of wearing layer preferably.It will be appreciated by persons skilled in the art that this wearing layer also can be other thickness, as the thickness that protrudes from above-mentioned surface is 6mm-10mm, the present embodiment is not specifically limited this.
For the ease of manufacturing, the installing hole in the scraper of the present embodiment is preferably circular hole.Meanwhile, the degree of depth of this circular hole is 6mm, and diameter is 6mm.Now, be arranged on size and circular hole that the wearing layer in circular hole is limited in this hole measure-alike, this size can guarantee drag head 2 and the good bonding strength of wearing layer, reduces the disengaging of wearing layer; Can also avoid the waste to wearing layer simultaneously.Certainly, above-mentioned circular hole can also be other sizes, and above-mentioned installing hole can also be other shapes, trapezoidal hole as shown in FIG. or the hole of other shapes.
The utility model also provides a kind of trommel mixer, comprises rotating shaft and is arranged on the scraper in rotating shaft; The scraper that this scraper the utility model Arbitrary Term embodiment provides.As shown in the figure, on the rabble arm 1 of scraper, also arrange by connecting hole, and be connected with above-mentioned rotating shaft by the bolt through this connecting hole.
The scraper that above-mentioned trommel mixer adopts the present embodiment to provide, has reduced the difficulty of processing of scraper, and its advantage is brought by scraper, concrete please refer to part relevant in above-described embodiment, at this, just repeats no more.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
