[0047] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0048] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0049] Example: A mobile shot blasting machine, see attached document. Figure 1 -Appendix Figure 8 The system includes a platform 1, a dust removal mechanism 2, a shot supply mechanism 3, and a shot blasting mechanism 4. The platform 1 is a component of a flatbed transport vehicle. The dust removal mechanism 2 is located at the top of the platform 1 near the front of the flatbed transport vehicle. The shot supply mechanism 3 is located at the top of the platform 1 and on the side of the dust removal mechanism 2 away from the front of the vehicle. The shot supply mechanism 3 can slide along the length of the platform 1. The shot blasting mechanism 4 is located on the side of the shot supply mechanism 3 away from the front of the vehicle. The shot blasting mechanism 4 can slide along the length of the platform 1 and also slide vertically on the shot supply mechanism 3. After the shot blasting mechanism 4 moves away from the top of the platform 1 and leaves the platform 1, it can contact the ground by sliding up and down on the shot supply mechanism 3.

[0050] When moving the shot blasting machine, the dust removal mechanism 2, the shot supply mechanism 3, and the shot blasting mechanism 4 are all located on the platform 1 and transported by a flatbed transport vehicle. When moving to the work site, the shot supply mechanism 3 and the shot blasting mechanism 4 are slid away from the front of the vehicle so that the shot blasting machine can detach from the platform 1 at the end away from the front of the vehicle. Then, the shot blasting mechanism 4 is slid down until it contacts the ground, and then the shot blasting work begins. When the work is finished and needs to be moved, simply move the shot blasting mechanism 4 upward, then slide the shot blasting mechanism 4 and the shot supply mechanism 3 towards the front of the vehicle and move them to the top of the platform 1, and then move them.

[0051] Specifically, the shot blasting mechanism 4 includes a shot blasting box 41, a shot blaster 49, and a transmission assembly. The shot blasting box 41 is configured with a shot blasting chamber inside. The shot blaster 49 is located inside the shot blasting chamber and is positioned near the top of the shot blasting chamber. The transmission assembly passes through the shot blasting chamber and is located below the shot blaster 49, thereby driving the workpiece through the shot blasting chamber.

[0052] Specifically, the transmission assembly includes a transmission roller 42, a connecting component 44, and a transmission belt 43. Two transmission rollers 42 are provided and are respectively arranged on both sides of the shot blasting box 41. The axis of the transmission roller 42 is horizontal and perpendicular to the transmission direction of the workpiece. The two ends of the transmission roller 42 are provided with connecting components 44 that connect the ends of the transmission roller 42 to the outside of the shot blasting box 41. The transmission rollers are arranged in a closed loop around the two transmission rollers 42. The transmission belt 43 is provided with through holes 47 for the shot to fall.

[0053] The connecting assembly 44 includes a fixed plate 441 and a rotating plate 442. Two fixed plates 441 are provided. The fixed plates 441 are fixedly connected to the outside of the shot blasting box 41. The fixed plates 441 are vertically arranged and perpendicular to the axis of the transmission roller 42. One end of the rotating plate 442 is inserted between the two fixed plates 441, and the other end is connected to the end of the transmission roller 42. The transmission roller 42 is rotatably connected to the rotating plate 442. The rotating plate 442 is rotatably connected to the two fixed plates 441, and the axis of rotation of the rotating plate 442 is parallel to the axis of the transmission roller 42.

[0054] By setting up the fixed plate 441 and the rotating plate 442, when transporting the shot blasting machine, the end of the rotating plate 442 away from the shot blasting box 41 is rotated upward until the rotating plate 442 is rotated vertically in the length direction and fixed on the shot blasting box 41. Then the rotating plate 442 is fixed, saving the space occupied by the shot blasting mechanism 4 during transportation. When using the machine after the shot blasting box 41 is in contact with the ground, it is only necessary to release the fixing of the rotating plate 442 to the shot blasting box 41 and rotate the rotating plate 442 to be horizontal in the length direction for use.

[0055] Specifically, the fixed plate 441 is provided with a positioning hole 4411 that passes through the fixed plate 441 along the axis of the conveyor roller 42, and the rotating plate 442 is also provided with a positioning hole 4411 that passes through the rotating plate 442 along the axis of the conveyor roller 42. When the rotating plate 442 rotates to a position where its length is parallel to the conveying direction of the workpiece, the positioning hole 4411 on the fixed plate 441 is aligned with the positioning hole 4411 on the rotating plate 442. The connecting assembly 44 also includes a connecting rod 443, which can pass through the positioning holes 4411 on the fixed plate 441 and the rotating plate 442 and cooperate with the positioning holes 4411. The connecting rod 443 is provided with a blocking plate 4431. When the connecting rod 443 passes through the rotating plate 442 and the two fixed plates 441, the blocking plate 4431 contacts the side of one of the fixed plates 441 away from the other fixed plate 441.

[0056] With the positioning hole 4411 and the connecting rod 443, when the rotating plate 442 rotates to a horizontal position in the length direction, the connecting rod 443 can be inserted into the positioning hole 4411 of the fixed plate 441 and the rotating plate 442, so that the position of the rotating plate 442 is fixed and prevents the position from shifting during use.

[0057] Specifically, the transmission assembly also includes a fixing assembly, of which two are provided and respectively disposed on both sides of the shot blasting box 41; the fixing assembly includes a support plate 48, an extension rod 45, and a control plate 46. Two support plates 48 are provided, fixedly connected to the side of the shot blasting box 41 near the top, with the two support plates 48 horizontally arranged and vertically aligned; two extension rods 45 are provided and respectively fixedly connected to the ends of two rotating plates 442 away from the shot blasting box 41; both ends of the control plate 46 are respectively fixedly connected to the ends of the two extension rods 45 away from the rotating plates 442; The support plate 48 is provided with two vertical holes 481 that penetrate the support plate 48 in a vertical direction, and the vertical holes 481 on the two support plates 48 are aligned one to one; the control plate 46 is provided with two through holes 47 that penetrate the control plate 46 in a direction perpendicular to the control plate 46. When the rotating plate 442 rotates to be vertical in the length direction, the control plate 46 rotates between the two support plates 48 and the two through holes 47 on the control plate 46 are aligned with the two through holes 47 on the support plate 48 respectively. The connecting rod 443 can pass vertically through the corresponding through holes 47 and the two vertical holes 481, and the blocking plate 4431 can contact the top of the top support plate 48.

[0058] With the support plate 48 and control plate 46 in place, when the rotating plate 442 rotates to a vertical position in the length direction, it is easy to fix the rotating plate 442 on the shot blasting box 41 by means of the connecting rod 443.

[0059] Specifically, the shot blaster 49 is provided with a feed pipe 491 extending out of the shot blasting box 41 at one end near the shot supply mechanism 3, and a feed hopper 492 is provided at the top of the feed pipe 491; the shot supply mechanism 3 includes a receiving box 31, and a supply pipe 312 for transmitting shot to the feed hopper 492 is fixedly connected to the side of the receiving box 31 near the shot blasting box 41; when the bottom of the shot blasting box 41 is in contact with the ground, the discharge end of the supply pipe 312 is located at the top of the feed hopper 492, and the feed hopper 492 is configured as a flexible feed hopper 492.

[0060] During the process of moving the feed hopper 492 up and down in the shot blasting box 41, it will collide with the supply pipe 312. By setting the feed hopper 492 as a flexible feed hopper, when the feed hopper 492 collides with the supply pipe 312, the deformation of the feed hopper 492 can allow the feed hopper 492 to pass smoothly through the supply pipe 312.

[0061] Specifically, the bottom of the shot blasting box 41 is provided with a bottom conveying mechanism arranged along the length of the vehicle plate 1. The bottom conveying mechanism is used to convey the shot to the side of the shot blasting chamber away from the front of the vehicle. The side of the shot blasting box 41 away from the front of the vehicle is provided with a bucket elevator 5. The bucket elevator 5 is used to lift the shot conveyed by the conveying mechanism to the top of the shot blasting box 41. The top of the shot blasting box 41 is provided with a top conveying mechanism 6. The top conveying mechanism 6 is used to transfer the shot lifted by the lifting mechanism to the receiving box 31.

[0062] The top conveying mechanism 6 and the bottom conveying mechanism are configured as screw conveyors.

[0063] Specifically, the bottom of the top conveying mechanism 6 near the front of the vehicle is fixedly connected to a discharge pipe 61. The top of the receiving box 31 is provided with a receiving hole 313 that cooperates with the discharge pipe 61. When the bottom of the shot blasting box 41 is in contact with the ground, the discharge pipe 61 is inserted into the receiving hole 313 and cooperates with the receiving hole 313.

[0065] The dust removal mechanism 2 is set as a bag filter. The bag filter draws air from the receiving box 31 through the connecting pipe 21. The air inlet of the receiving box 31 allows outside air to enter the receiving box 31 and pass through the falling shot before entering the connecting pipe 21. During the process of passing through the shot, the debris cleaned off the workpiece in the shot blasting box 41 is carried into the connecting pipe 21 and into the bag filter. The bag filter filters the debris in the air before discharging the air.

[0066] Specifically, the top of the car plate 1 is provided with two slide rails 11 arranged along the length of the car plate 1; the bottom of the container box 31 and the shot blasting box 41 are provided with rollers that contact the two slide rails 11 respectively, and the bottom of the container box 31 and the shot blasting box 41 are provided with at least two rollers corresponding to each slide rail 11.

[0067] Specifically, two fixing blocks 311 are fixedly connected to the side of the receiving box 31 near the shot blasting box 41. The length direction of the two fixing blocks 311 is vertically arranged. A vertical groove 3111 is provided on the side of the fixing block 311 near the shot blasting box 41, which penetrates the shot blasting box 41 vertically.
