[0037] Example 2:

[0038] Based on Example 1, please refer to Figure 5 and Figure 6 .

[0039] Specifically, the support rod 19 is connected in the atmospheric hand hole 10, the middle end of the support rod 19 is rotationally connected with the rotating rod 20, the stirring rod 21 is connected at one end of the rotating rod 20, the other end of the rotating rod 20 is rotationally connected with the extension rod 22, the inserting assembly 23 comprises the support block 231, the support block 231 is connected at one side of the stirring rod 21 close to the atmospheric hand hole 10, the two sides of the support block 231 are both provided with the first sliding groove 232, the two first sliding grooves 232 are both slidably connected with the sliding block 233, the two sliding blocks 233 are both provided with the spring 234 at one side of the two first sliding grooves 232, the two sliding blocks 233 are both connected with the stop block 235 at the sides away from each other, the limiting assembly 24 comprises the limiting block 241, the limiting block 241 is connected at one side of the support rod 19 close to the stirring rod 21, the limiting block 241 is provided with the second sliding groove 242 at one side close to the stirring rod 21, the two sides of the second sliding groove 242 are both provided with the limiting groove 243, the two limiting grooves 243 are both provided with the slope at one side, and the two limiting grooves 243 are both matched with the two stop blocks 235. Through the above technical scheme, through the rotating rod 20, the extension rod 22 and the stirring rod 21, when the material in the feeding cylinder 9 is blocked, the stirring rod 21 is rotated to stir and push the blocked material in the feeding cylinder 9, so that the material falls into the auger pipe 1 smoothly and is fed, when not in use, the stirring rod 21 is pulled into the atmospheric hand hole 10, the support rod 19 at one side of the stirring rod 21 is inserted into the second sliding groove 242 at one side of the limiting block 241, the limiting grooves 243 on the limiting block 241 are used for fixing and limiting the stop blocks 235 at the two sides of the support block 231, so that the stirring rod 21 is fixed in the atmospheric hand hole 10, and the stirring rod 21 does not affect the feeding in the feeding cylinder 9 when not in use.

[0040] The working principle of the present invention is as follows: when in use, the staff installs the auger tube 1 on the rubber particle compression equipment through the second connecting flange 11, aligns the discharge port 5 on one side of the auger tube 1 with the feed port of the compression equipment, and the staff puts the rubber particles used for oil refining into the feed barrel 9. Due to the oblique setting of the feed barrel 9, the rubber particles slide in the feed barrel 9 and fall into the two auger tubes 1, and the two parallel shaft helical gear reducers 18 work to drive the coupling 16 to rotate, and the parallel shaft helical gear reducer 18 itself has the function of deceleration, which effectively ensures the rotation rate of the spiral blade 4, and increases the torque by deceleration, so that when a large amount of rubber particles are transmitted through the spiral blade 4, the spiral blade 4 can maintain normal rotation, and the shaft head 13 is driven by the coupling 16 to rotate in the spherical roller bearing 15 to drive the first center tube 2 and the second center tube 3 to rotate, and drive the two spiral blades 4 to rotate in the two auger tubes 1 to transport the material falling into the auger tube 1, and can transport it within the same time. The material in the feed barrel 9 is stirred and pushed, so that the material blocked in the feed barrel 9 falls smoothly into the auger tube 1, and then driven by the spiral blades 4 to perform the feeding operation;

[0041] After the feed barrel 9 is unblocked, the staff can pull the extension rod 22 to drive the rotating rod 20 to move on the support rod 19, and drive the stirring rod 21 to move in the feed barrel 9 into the normal pressure hand hole 10, so as to avoid the stirring rod 21 in the feed barrel 9 from blocking the material discharge, which may easily cause the feed barrel 9 to be blocked. During the pulling process, the support block 231 first contacts the limit block 241, and the support block 231 enters the second chute 242 on the side of the limit block 241. The slope setting of the second chute 242 makes the support block 231 The blocks 235 on both sides of the support block 231 can also enter the second chute 242. In the process of gradually entering, the blocks 235 on both sides of the support block 231 are squeezed by the second chute 242, so that the blocks 235 on both sides of the support block 231 slide close to each other in the first chute 232 on both sides of the support block 231, pushing the sliders 233 on one side of the two blocks 235 to move closer to each other. The two sliders 233 squeeze the two springs 234 at the same time, causing the springs 234 to undergo elastic deformation, thereby causing the springs 234 to produce an impact on the sliders 233. The two blocks 235 are pushed out of the two first slots 232, and the two blocks 235 enter the two limiting slots 243 respectively, thereby fixing the support block 231 on the limiting block 241. After moving into the normal pressure hand hole 10, it is fixed to prevent the stirring rod 21 from entering the feed barrel 9 during the loading process. After limiting the support block 231 by the limit block 241, the staff can rotate the extension rod 22 so that the extension rod 22 is perpendicular to the rotating rod 20, so that the extension rod 22 is retracted into the normal pressure hand hole 10. When the feed barrel 9 is blocked and cleaned next time, the staff can push the rotating rod 20 to move the support block 231 out of the second slide groove 242 on the side of the limit block 241, and then operate the stirring rod 21.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
