As shown in fig. 1, a grain conveying device capable of adjusting a feeding angle comprises a machine body 1 and a conveying part 2. As disclosed in the prior art, in the present embodiment, the conveying section 2 includes a conveying bracket 21, a conveying roller 22, a conveying motor (not shown in the figure), a conveying belt 23, and an idler 24; generally, there are two conveying rollers 22, and the two conveying rollers are respectively mounted on the front and rear ends (the rear end refers to a feeding end and the front end refers to a discharging end) of the conveying bracket 21 through bearings, and the conveying belt 23 is wound on the two conveying rollers 22 and moves under the driving of the conveying rollers 22; the above-mentioned idler 24 is installed on the conveying bracket 21 between the two conveying rollers 22, and the idler 24 is used for supporting the conveying belt 23 to prevent the grain from pressing the conveying belt 23.

In this embodiment, the front part of the bottom surface of the machine body 1 is fixedly connected with a walking roller 11, and the rear part is rotatably connected with a steering roller 12; it can be understood that the bracket for mounting the walking roller 11 is fixedly mounted relative to the machine body 1, and the bracket for mounting the steering roller 12 is rotatably connected relative to the machine body 1, so that when the steering roller 12 is rotated, the moving direction of the machine body 1 can be adjusted, and the steering function is realized.

For example, in the present embodiment, a hinge base is fixed to both the rear portion of the lower side of the conveying support 21 and the front portion of the top surface of the machine body 1, and a pin hole is formed in the hinge base, and the pin hole penetrates through the two hinge bases, so that the conveying support 21 is hinged to the machine body 1.

The conveying support 21 is connected with a walking sliding table 3, and the walking sliding table 3 moves on the conveying support 21 along the direction parallel to the running and feeding directions of the conveying belt 23; in this embodiment, it is preferable that a slide rail (not shown in the figure) is fixed on the conveying support 21, and a slide block or a slide groove adapted to the slide rail is correspondingly arranged on the walking sliding table 3, so that the walking sliding table 3 can move on the conveying support 21 in a sliding manner by means of the slide rail.

Or in another embodiment, a roller can be rotatably connected to the walking sliding table 3, and a wheel rail adapted to the roller is correspondingly and fixedly connected to the conveying support 21, so that the walking sliding table 3 can move on the conveying support 21 in a rolling manner by depending on the wheel rail.

The lower side of the walking sliding table 3 is hinged with a connecting rod 4, and the other end of the connecting rod 4 is hinged with the front part of the top surface of the machine body 1; similarly, in this embodiment, the lower side of the walking sliding table 3 and the front portion of the top surface of the machine body 1 are both fixed with the hinge bases, and the connecting rod 4 and the hinge bases are connected through the pin shaft at the two ends of the connecting rod 4 and the pin holes, so that the connecting rod 4 and the hinge bases can rotate mutually, and the hinge connection is realized.

Meanwhile, an adjusting motor (not shown in the figure) is fixed on the walking sliding table 3, the output end of the adjusting motor is fixedly connected with a gear 5 through a key, and correspondingly, a rack 6 matched with the gear 5 is fixedly installed on the conveying support 21. The adjusting motor rotates, and the walking sliding table 3 is driven to move on the conveying support 21 through the meshing of the gear 5 and the rack 6, so that the connecting rod 4 rotates relative to the machine body 1, the purpose of adjusting the angle of the conveying support 21 is achieved, and the purpose of adjusting the discharging height of the discharging end of the conveying part 2 can be achieved through adjusting the angle of the conveying support 21.

In order to prevent the uncontrolled movement of the walking sliding table 3 during the use process, the adjusting motor is a self-locking motor in this embodiment, and the gear 5 is made to be unrotatable by locking the adjusting motor, so that the walking sliding table 3 cannot move relative to the conveying support 21.

When the device is used, the rotation direction of the adjusting motor is controlled according to actual needs, the walking sliding table 3 is driven to move on the conveying support 21 by rolling the gear 5 on the rack 6, and when the walking sliding table 3 moves, the angle position of the connecting rod 4 changes, so that the inclination angle of the conveying support 21 changes accordingly, the purpose of adjusting the discharging height of the discharging end of the conveying part 2 is achieved, and the effect of flexibly adjusting the discharging height of the conveying part 2 under different use working conditions is achieved; specifically, when the unloading height is too high, the walking sliding table 3 is made to move towards the front end of the conveying support 21, so that the inclination angle of the conveying support 21 is reduced, the purpose of reducing the unloading height is realized, and the raised dust is reduced; when the unloading height is too low, the walking sliding table 3 moves reversely.

On the basis of the above embodiment, the connecting rod 4 can be a threaded sleeve telescopic rod in another embodiment, and the length of the connecting rod 4 can be adjusted in advance during use, so that when the walking sliding table 3 moves, the length of the connecting rod 4 as a movement radius can be more fit to change the actual movement stroke of the walking sliding table 3 into the rotation angle of the conveying support 21.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
