Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] Please see Figure 1-7In this embodiment of the present invention, a shot blasting device for the outer wall of a ductile iron valve includes: a support frame 100, a conveying mechanism 200, and a shot blasting mechanism 300. A fixed shell 110 is fixedly connected to the top of the support frame 100. The conveying mechanism 200 is fixed to the fixed shell 110. The conveying mechanism 200 includes two fixed plates 210, which are respectively fixedly connected to both sides of the bottom of the fixed shell 110. Rotating rods 220 are rotatably connected to both ends of the two fixed plates 210. Synchronous gears 221 are sleeved and fixed to both ends of the rotating rods 220. Two... A synchronous toothed belt 222 is provided, and the two ends of the synchronous toothed belt 222 are respectively meshed with the corresponding synchronous gear 221. Multiple connecting holes 223 are evenly opened on the synchronous toothed belt 222. Multiple bearing components are evenly arranged between the two synchronous toothed belts 222.

[0041] Specifically, multiple load-bearing components are used to facilitate the support and fixation of multiple ductile iron valves, and the load-bearing components are also used to limit and fix ductile iron valves of different sizes. Then, by starting the second motor 230, the second motor 230 drives the corresponding rotating rod 220 to rotate, thereby causing the two synchronous gears 221 to rotate, which in turn causes the two synchronous toothed belts 222 to rotate. The rotation of the two synchronous toothed belts 222 drives the multiple load-bearing components and the multiple ductile iron valves to rotate. The shot blasting mechanism 300 is used to facilitate the shot blasting treatment of the ductile iron valves, and multiple rubbing components are used to facilitate the rotation of the corresponding load-bearing components and ductile iron valves, thereby ensuring the shot blasting treatment effect of the shot blasting mechanism 300.

[0042] like Figure 3-7As shown, in this embodiment, the thickness of the synchronous gear 221 is the same as the width of the synchronous toothed belt 222. The bearing assembly includes: a connecting rod 240, a round rod 270, and a fixing rod 280. The connecting rod 240 is disposed between two connecting holes 223. Both ends of the connecting rod 240 are fixedly connected to shafts 241, and the shafts 241 are fixedly connected to the inner sidewalls of the corresponding connecting holes 223. The round rod 270 is rotatably connected to one end of the connecting rod 240. A rubbing wheel 271 is fixedly connected to the bottom of the round rod 270. A bearing plate 272 is fixedly connected to the top of the 0, and a bearing shell 273 is fixedly connected to the top of the bearing plate 272. Multiple sliding through holes 274 are evenly provided on the outer side wall of the bearing shell 273. A fixing rod 280 is fixedly connected to the inner top surface of the bearing shell 273. Multiple pressing blocks 282 are evenly provided on the outer side of the fixing rod 280, and the pressing blocks 282 are slidably connected to the corresponding sliding through holes 274. Multiple compression springs 281 are fixedly connected between one end of the pressing block 282 and the fixing rod 280. The rubbing assembly includes: a connecting plate 25. 0.

The connecting frame 260 is fixedly connected to the other side of the connecting plate 250. The rectangular shell 290 is fixedly connected to one end of the connecting frame 260. A connecting notch is opened on the top of one side of the rectangular shell 290. A motor 291 is fixedly connected to the inner bottom surface of the rectangular shell 290, and the output end of the motor 291 is fixedly connected to... The second rubbing roller 292 passes through the connecting notch and makes pressing contact with the corresponding first rubbing roller 271. The shot blasting mechanism 300 includes: multiple shot blasting machine bodies 350 and multiple feeding pipes 360. The multiple shot blasting machine bodies 350 are all located on the top of the inner side of the fixed shell 110. Adjustment components are provided on the outer side of the multiple shot blasting machine bodies 350. The multiple feeding pipes 360 are all fixedly connected to the top of the fixed shell 110. The bottom of the multiple feeding pipes 360 are respectively connected and fixed to the feed port of the corresponding shot blasting machine body 350.

[0043] In this embodiment, the support plate 272 facilitates the support and fixation of the ductile iron valve. After one end of the ductile iron valve is inserted into the support shell 273, multiple extrusion blocks 282 and multiple compression springs 281 are used to extrude and fix the ductile iron valve, which is convenient for extruding and fixing ductile iron valves of different sizes. The moving synchronous toothed belt 222 drives the support assembly and the ductile iron valve to move. When the ductile iron valve moves to the position of the corresponding shot blasting machine body 350, multiple shot blasting machine bodies 350 are started, which facilitates the multiple shot blasting machine bodies 350 to perform shot blasting. The ductile iron valve undergoes shot blasting. The connecting plate 250 can shield the synchronous gear 221 and synchronous toothed belt 222, preventing shot from entering the synchronous toothed belt 222 and affecting its normal operation. By starting the motor 291, the rubbing wheel 292 is rotated, which in turn rubs the corresponding round rod 270, causing the bearing plate 272, bearing shell 273, and ductile iron valve to rotate, thus ensuring the shot blasting effect on the ductile iron valve.

[0044] Example 2

[0045] Based on Embodiment 1, in order to facilitate the collection of shot and to adjust the distance between the shot blasting machine body 350 and the ductile iron valve according to the size of the ductile iron valve, the shot blasting mechanism 300 can be adapted to ductile iron valves of different sizes.

[0046] like Figure 2-7 As shown, in this embodiment, a collection shell 120 is fixedly connected to the bottom of the fixed shell 110, and the bottom of one side of the collection shell 120 is fixedly connected to the support frame 100. A conveying pipe 121 is fixedly connected to the bottom of the collection shell 120. The adjustment assembly includes: a motor 310, a moving plate 320, two limiting rods 330 and multiple moving shells 340. One end of the motor 310 is fixedly connected to an inner side wall of the fixed shell 110. A screw 311 is fixedly connected to the output end of the motor 310. The moving plate 320 is screwed to the outside of the screw 311. One end of each of the two limiting rods 330 is fixedly connected to an inner side wall of the fixed shell 110. The two limiting rods 330 are slidably connected to both ends of the moving plate 320. Multiple moving shells 340 are fixedly connected to the bottom of the moving plate 320. Both ends of the moving shells 340 are fixedly connected to the corresponding shot blasting machine body 350.

[0047] In practice, the collection shell 120 and the conveying pipe 121 are used to collect the shot thrown out by the shot blasting machine body 350. By starting the motor 310, the screw 311 is rotated. The two limit rods 330 limit the moving plate 320, thereby allowing the moving plate 320, multiple moving shells 340 and multiple shot blasting machine bodies 350 to move. This facilitates the adjustment of the distance between the shot blasting machine body 350 and the ductile iron valve, making the shot blasting mechanism 300 applicable to ductile iron valves of different sizes and improving the practicality of the shot blasting treatment device for the outer wall of the ductile iron valve.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
