[0019] 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.

[0020] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0021] Example: A fully hydraulic shot blasting machine suitable for outdoor operation, see attached document. Figure 1 -Appendix Figure 7 The system includes a shot blasting chamber 1, a conveying mechanism 2, a shot blaster, a collecting mechanism 3, a lifting mechanism 4, a collecting box 6, and hydraulic motors. Workpieces requiring shot blasting pass through the shot blasting chamber 1 and undergo shot blasting within it. The conveying mechanism 2 drives the workpiece through the shot blasting chamber 1. The shot blaster is located within the shot blasting chamber 1 to project shot onto the workpiece passing through it. The collecting mechanism 3 collects the shot that falls to the bottom of the shot blasting chamber 1 after impacting the workpiece. The lifting mechanism 4 lifts the shot collected by the collecting mechanism 3. The collecting box 6 receives the shot lifted by the lifting mechanism 4 and transfers the collected shot to the shot blaster. Multiple hydraulic motors are provided to power the shot blaster, the conveying mechanism 2, the collecting mechanism 3, and the lifting mechanism 4.

[0022] In this embodiment, the hydraulic motor is configured so that when the shot blasting machine is used outdoors, it can work normally even in rainy weather, ensuring the normal operation of the shot blasting machine in rainy weather.

[0023] Specifically, this embodiment also includes a cleaning and drying mechanism 5, which is disposed between the top of the lifting mechanism 4 and the collection box 6. The cleaning and drying mechanism 5 is used to clean and dry the projectiles in rainy weather.

[0024] When using a shot blasting machine in rainy weather, rainwater will inevitably enter the shot blasting chamber 1 and mix with the shot. However, the cleaning and drying mechanism can dry and remove impurities from the shot before it enters the collection box 6, ensuring that the shot can be smoothly and high-speed ejected after entering the shot blaster through the collection box 6.

[0025] Specifically, the cleaning and drying mechanism 5 includes a drying box 51, an air supply box 52, and an air outlet pipe 53. One end of the drying box 51 is connected to the top of the lifting mechanism 4, and the other end is connected to the top of the collection box 6 near the lifting mechanism 4. The drying box 51 is inclined upward at the end near the lifting mechanism 4. The air supply box 52 is fixedly connected to the bottom of the drying box 51 and is used to blow air into the drying box 51. Several air outlet pipes are fixedly connected to the top of the drying box 51 and are used to discharge air upward.

[0026] Specifically, the bottom of the drying box 51 is set as an inclined plate 511, and a number of blocking rods are fixedly connected to the top of the inclined plate 511. The length direction of the inclined plate 511 is set along the inclined direction of the air supply box 52, and the width direction of the inclined plate 511 is set horizontally. The length direction of the blocking rods is set along the width direction of the inclined plate 511. Multiple blocking rods 512 are provided, and the multiple blocking rods 512 are arranged along the length direction of the inclined plate 511.

[0027] Specifically, the blocking rod 512 is provided with a guide surface. The side of the guide surface closer to the lifting mechanism 4 is in contact with the inclined plate 511, and the side away from the lifting mechanism 4 is inclined upward.

[0028] Specifically, the inclined plate 511 is provided with several sets of clearance holes 513. The clearance holes 513 penetrate the inclined plate 511 in a direction perpendicular to the inclined plate 511, and the length direction of the clearance holes 513 is set along the width direction of the inclined plate 511. Each blocking rod 512 corresponds to a set of clearance holes 513. A set of clearance holes 513 is set on the side of the corresponding blocking rod 512 away from the lifting mechanism 4. Multiple clearance holes 513 in the same set are arranged along the inclination direction of the inclined plate 511.

[0029] The lifting mechanism 4 lifts the shot into the drying chamber 51, where it rolls down the inclined plate 511. After passing a stop bar 512, the shot falls back onto the inclined plate 511 and impacts it. The impact shakes off the water and impurities on the shot, and at the moment of impact, the water and impurities pass through the clearance hole 513 into the air supply box 52 due to their own inertia. The air blown upward through the clearance hole 513 also carries away the moisture on the surface of the shot as it passes through it, thus cleaning and drying the shot.

[0030] Specifically, the length of the air outlet pipe 53 is parallel to the width direction of the inclined plate 511. The air inlet of the air outlet pipe 53 is connected to the drying box 51, and the air outlet is located on the side away from the drying box 51. An arc-shaped plate 531 is provided around the air outlet of the air outlet pipe 53. The axis of the arc-shaped plate 531 is parallel to the length direction of the air outlet pipe 53. The two ends of the arc-shaped plate 531 are respectively connected to the two ends of the air outlet pipe 53 through two connecting plates 532.

[0031] The curved plate 531 allows air passing through the drying chamber 51 to be smoothly discharged through the air outlet of the air outlet pipe 53, while rainwater from the outside is also prevented from entering the drying chamber 51 by the curved plate 531.

[0032] Specifically, the end of the air supply box 52 near the collection box 6 is configured as a sewage discharge section, and a sewage discharge rod 54 is provided in the sewage discharge section. The length direction of the sewage discharge rod 54 is arranged along the width direction of the inclined plate 511. The bottom of the air supply box 52 is configured as a sewage discharge plate 521, the length direction of the sewage discharge plate 521 is arranged along the length direction of the inclined plate 511, and the width direction of the sewage discharge plate 521 is arranged along the width direction of the sewage discharge plate 521. Sewage discharge holes 522 are provided on both sides of the air supply box 52, which penetrate the side wall of the air supply box 52 along the length direction of the sewage discharge rod 54. The top and bottom of the sewage discharge holes 522 are aligned with the bottom of the inclined plate 511 and the top of the sewage discharge plate 521, respectively. Two movable plates 55 are fixedly connected to the sewage discharge rod 54. The two movable plates 55 can be located in the two sewage discharge holes 522 respectively to close the two sewage discharge holes 522, and the two movable plates 55 can slide in the air supply box 52 along the length direction of the sewage discharge rod 54. The cleaning and drying mechanism 5 also includes an air inlet pipe 56, which is fixedly connected to the air supply box 52 near the inclined top.

[0033] By setting the connection position between the air inlet pipe 56 and the air supply box 52 and tilting the drain plate 521, the impurities that enter the air supply box 52 through the clearance hole 513 will move to the drain section of the air supply box 52. Then, the operator pulls the drain rod 54 to slide it, and then the two moving plates 55 push the impurities out of the two drain holes 522.

[0034] In rainy weather, in order to ensure the drying of the projectiles, the air inlet pipe 56 continues to supply air to the air supply box 52. In dry weather, since impurities will not adhere to the projectiles, the air inlet pipe 56 stops supplying air, allowing impurities to smoothly enter the air supply box 52 through the clearance hole 513.

[0035] Specifically, the collection mechanism 3 includes a collection pipe 31, a collection hopper, a rotating rod 32, and a spiral plate 33. The top of the collection pipe 31 is open, and the length of the collection pipe 31 is horizontal. The collection hopper is fixedly connected to the bottom of the shot blasting chamber 1 and to the top of the collection pipe 31. The bottom of the collection pipe 31 is semi-circular, and its axis is set along the length of the collection pipe 31. The rotating rod 32 is rotatably connected to the collection pipe 31 and is coaxial with the semi-circular part at the bottom of the collection pipe 31. The spiral plate 33 is fixed outside the rotating rod 32, and the outer side of the spiral plate 33 is in contact with the semi-circular inner wall of the collection pipe 31. The semi-circular part at the bottom of the collection pipe 31 is set as a filter screen.

[0036] By setting the bottom of the collection pipe 31 as a water filter, most of the rainwater entering the shot blasting chamber 1 is discharged downward through the water filter, thereby reducing the working pressure of the cleaning and drying mechanism 5.

[0037] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
