In the present invention, unless explicitly stated or limited otherwise, the terms "connected," "fixed," "disposed," and the like are to be understood in a broad sense, either fixedly connected or detachably connected, or integrally formed; may be directly connected or indirectly connected through an intermediate, unless otherwise specifically limited. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Relational terms such as first, second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

As shown in fig. 1-2, the conventional scraper conveyor frame, especially the headstock and tailstock portions, includes a first frame body 1, the first frame body 1 is of a front opening type, and a first sprocket shaft group 2 is inserted along a front opening 3 of the first frame body. Then, pressing blocks 4 which press two ends of the first chain wheel shaft group 2 are placed on the first frame body 1 through the front opening 3. A first positioning pin hole is formed in the first chain wheel shaft group 2, a corresponding second positioning pin hole is also formed in the first frame body 1 or the pressing block 4 and used for axially positioning the first chain wheel shaft group 2 on the first frame body 1, and the first chain wheel shaft group 2 and the pressing block 4 are positioned through a first positioning pin 5; the pressing block 4 and the first frame body 1 are fixed through a first fastening piece 6, and the first fastening piece 6 can be a bolt. Set up the rectangle locating piece on the briquetting 4, correspond the position and set up the rectangle constant head tank on the first support body 1, fix a position through rectangle locating piece and rectangle constant head tank between briquetting 4 and the first support body 1. Wherein the first sprocket shaft group 2 generally employs an integral sprocket. The disadvantages of this structure are: firstly, the method comprises the following steps: the space for accommodating the first chain wheel shaft group 2 is divided into two parts, the hole in the shape of a half arc is arranged on the pressing block 4, and the hole in the shape of the other half arc is arranged on the first frame body 1, so that the strength of the whole shaft group installation structure is reduced. Secondly, the method comprises the following steps: the processing that holds the hole of first sprocket shaft group 2 between briquetting 4 and the first support body 1 at first needs separately to be preprocessed, then needs the equipment back cooperation processing round hole to guarantee the concentricity of two semicircle arcs. Thirdly, the method comprises the following steps: the axial between briquetting 4 and the first support body 1 needs reliable location, and prior art adopts rectangle strip and groove to fix a position, and processing is complicated, the degree of difficulty is high. And fourthly, the headstock is in a front opening type, and the strength and the rigidity are poor.

As shown in fig. 3-6, the utility model relates to an integral frame of scraper conveyor, including support body 7 and the sprocket shaft group 8 of setting in support body 7, sprocket shaft group 8 includes axle group 80 and sets up the sprocket 81 on axle group 80. The frame body 7 is provided with sprocket shaft group mounting holes 70 corresponding to two ends of a shaft group 80 of the sprocket shaft group 8, and two ends of the shaft group 80 are fixedly connected with the frame body 7. The frame refers to a head frame or a tail frame of the scraper conveyor. The structure of the frame body 7 refers to the attached drawings. The structure of the head frame and the tail frame of the scraper conveyor, which is irrelevant to the invention of the patent, belongs to the prior art and is not described in detail. The sprocket shaft set mounting holes 70 are generally circular and correspond to the shape of a conventional shaft. Of course, the shape may be other shapes as long as the function of the scraper conveyor is not affected.

Furthermore, two ends of the shaft group 80 of the sprocket shaft group 8 are fixed on the frame body 7 through positioning pins; the frame body 7 is provided with a positioning pin mounting hole 71 communicated with the sprocket shaft group mounting hole 70, the shaft group 80 is provided with a positioning pin hole 83 corresponding to the positioning pin mounting hole 71, and the positioning pin 9 penetrates through the positioning pin mounting hole 71 and the positioning pin hole 83 to fix the frame body 7 and the shaft group 80. The fixing mode of the positioning pin 9 is convenient and quick to install and disassemble. Other conventional fastening means are also possible, for example by bolting. Any end of the sprocket shaft group 8 is fixed by the positioning pin 9, so that the fixing function can be realized, but the sprocket shaft group is not stable, and one end of the sprocket shaft group is easy to damage due to overlarge stress.

A stop pin 10 for fixing the positioning pin 9 is arranged on the frame body 7; the positioning pin 9 is provided with a stop pin hole 90 and a stop pin mounting hole 72 corresponding to the stop pin hole 90 on the frame body 7, the stop pin mounting hole 72 is communicated with the positioning pin mounting hole 71, and the stop pin 10 passes through the stop pin mounting hole 72 and the stop pin hole 90.

The scraper conveyer is stressed greatly in the working environment, and when the headstock or the tailstock receives impact, the pin shaft is easy to shake and has the possibility of separation. The stop pin 10 for fixing the positioning pin 9 is arranged on the frame body 7, so that the front and rear positions of the positioning pin 9 are not changed, and the shaft group 80 is fixed in position in the frame body 7. The stop pin 10 and the positioning pin 9 are convenient to mount and dismount, and the whole headstock is simple, convenient and quick in dismounting and mounting process.

The sprocket 81 is preferably a combination sprocket comprising at least two sprocket plates 82, the sprocket plates 82 being disposed about the shaft set 80 and adjacent sprocket plates 82 being secured together by sprocket fasteners. As shown in the drawings in the specification, in a specific embodiment, the sprocket 81 may include upper and lower sprocket plates that are identical in construction and disposed about the axle set 80 and secured together by sprocket fasteners. The sprocket fasteners may be conventional fasteners such as bolts. The combined chain wheel belongs to the prior art, and is not described in detail, and specific reference can be made to patents related to combined chain wheels such as patent CN 205592348U. Although the integrated sprocket can be mounted on the frame 7 of the present invention, the mounting manner is troublesome. The utility model discloses in, the structure of support body 7 decides sprocket shaft group 8's mounting means and dismantlement mode. It was further determined that the composite sprocket was the most suitable sprocket.

The utility model discloses 8 installation processes of well sprocket shaft group: the shaft assembly portion 80 of the sprocket shaft assembly 8 is first inserted through the sprocket shaft assembly mounting hole 70 on one side of the frame body 7, then moved and inserted through the sprocket shaft assembly mounting hole 70 on the other side of the frame body 7. The two positioning pin holes 83 on the shaft group 80 of the sprocket shaft group 8 are respectively aligned with the two positioning pin mounting holes 71 on the frame body 7, the positioning pins 9 are mounted, and the positions of the positioning pins 9 are adjusted so that the stop pin holes 90 on the positioning pins 9 are aligned with the stop pin mounting holes 72 on the frame body 7. The stop pin 10 is inserted through the stop pin mounting hole 72 of the frame body 7 and the stop pin hole 90 of the positioning pin 9. The stopper pin 10 restricts the movement of the positioning pin in the longitudinal direction of the positioning pin attachment hole 71.
