[0015] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0016] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0017] like Figures 1 to 3 As shown, a feeding device for a shot blasting machine includes a pit 2 opened on the ground in front of a shot blasting machine 1, a liftable material trough 3 is arranged in the pit, the rear side of the material trough is open, and a material guide plate 4 is hinged at the bottom of the opening at the rear side of the material trough, which can swing up and down and can extend to the inlet and outlet of the front side of the shot blasting machine after swinging down, and a material blocking plate is arranged on the left and right sides of the material guide plate to prevent the workpiece from falling from both sides. In the initial state, the material trough 3 is in a descending position, and the material trough 3 can be flush with the ground or slightly higher than the ground, so that workers can place the workpiece to be cleaned in the material trough; then the material trough rises to the front of the inlet and outlet of the shot blasting machine, generally rising to a height of 1.2~1.5m, and then the material guide plate 4 swings down so that its front end tilts downward and extends to the inlet and outlet of the shot blasting machine, and the workpiece can slide down along the material guide plate 4 into the shot blasting machine, and the worker can manually push the workpiece in the material trough to the material guide plate 4.

[0018] In this embodiment, in order to further reduce the labor intensity and reduce the manual pushing operation of workers, the material trough is added with a unloading and dumping function: a scissor-type lift 5 is provided in the pit to drive the lifting of the material trough, and the bottom surface of the rear end of the material trough is hinged to the table of the scissor-type lift. The two sides of the bottom surface of the front end of the material trough and the table of the scissor-type lift are connected to a hydraulic cylinder A6 for driving the front end of the material trough to lift; when the hydraulic cylinder A6 is extended, the front end of the material trough is lifted to tilt the material trough, and the workpiece in the material trough can automatically slide to the guide plate 4, and then slide down along the guide plate 4 into the shot blasting cleaning machine.

[0019] In this embodiment, L-shaped mounting plates 7 are fixedly connected to both sides of the front end of the table of the scissor-type lift, and the two ends of the hydraulic cylinder A are respectively hinged to the bottom surface of the trough and the L-shaped mounting plate.

[0020] In this embodiment, brackets 8 are fixedly connected to both sides of the rear part of the material trough, a hydraulic cylinder B9 is connected between the bracket and the material guide plate, and both ends of the hydraulic cylinder B are hinged to the bracket and the material guide plate respectively.

[0021] In addition to being used for loading, the feeding device of the shot blasting machine can also be used for discharging. When discharging, the height of the trough is lower than the height of the inlet and outlet of the shot blasting machine, and the front end of the guide plate is tilted upward and extends to the vicinity of the lower edge of the inlet and outlet of the shot blasting machine. The workpieces transported by the shot blasting machine will also slide into the trough along the guide plate. In the specific implementation process, the discharging can also be done without using the feeding device of the utility model, and a material frame can be placed directly under the inlet and outlet of the shot blasting machine to receive the material.

[0022] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values ​​to be exhaustive, the utility model discloses only some numerical values ​​to illustrate the technical solution of the utility model, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the utility model.

[0023] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0024] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
