DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0020] according to Figure 1-6 As shown, a shot blasting machine that is easy to load includes a frame 1, an active roller and two transmission rollers are arranged inside the frame 1, the active roller and the transmission rollers are distributed in a triangle, and a crawler is sleeved on the outer wall of the active roller and the transmission roller. A feed port 2 is provided on one side of the crawler of the frame 1, and a loading mechanism is provided at the feed port 2. The loading mechanism includes a loading barrel 3, a shaftless spiral blade 4 is provided in the loading barrel 3, and the end of the shaftless spiral blade 4 is connected to the rotating motor 6 through a rotating shaft 5. The bottom of the loading barrel 3 is provided with a driving mechanism for driving the end of the loading barrel 3 in and out of the frame 1.

[0021] In the above-mentioned specific technical solution, the shaftless spiral blade 4 transports the workpiece in the loading barrel 3 to the crawler belt by rotation, and during the transportation process, the loading barrel 3 is driven by the driving mechanism to gradually move out of the frame 1, so that the workpiece in the loading barrel 3 is evenly distributed on the crawler belt, thereby improving the cleaning effect of the workpiece and realizing automatic loading of the workpiece.

[0022] The loading barrel 3 is provided with a storage bin 7 away from the opening end, and the workpiece enters the loading barrel 3 through the storage bin 7 .

[0023] The driving mechanism includes a support frame 8 for supporting the loading barrel 3, the bottom of the support frame 8 is slidably connected to the base 9, and the base 9 is provided with a loading screw 10 that is connected to the support frame 8. One end of the loading screw 10 is connected to the mobile motor, and the mobile motor is installed on the base 9. The driving mechanism enables the loading barrel 3 to enter and exit the frame 1, so that the workpiece in the loading barrel 3 can fall evenly onto the crawler.

[0024] The frame 1 is provided with a discharge port 11, a guide plate 12 is provided at the discharge port 11, a conveyor belt 13 is provided below the guide plate 12, and a collection box 14 for collecting workpieces is placed on the conveyor belt 13. When the workpieces are cleaned, the door of the discharge port 11 is opened, and the crawler pushes the workpiece out during rotation, and the workpiece falls into the collection box 14 through the guide plate 12.
