[0019] See also Figures 1 to 4 A three-position four-way anti-blocking device comprises: a feed pipe 1, a drop pipe 2, a hydraulic push rod 8, and a scraper assembly 9.

[0020] See also Figure 1 In one embodiment, the feed pipe 1 discharges downward, and the discharge pipe 2 slides horizontally (left and right) at the lower end of the feed pipe 1. The discharge pipe 2 is mainly composed of a left discharge pipe 3, a middle discharge pipe 4, and a right discharge pipe 5 fixed together. The left discharge pipe 3, the middle discharge pipe 4, and the right discharge pipe 5 are connected by welding a connecting plate 7. The left discharge pipe 3, the middle discharge pipe 4, and the right discharge pipe 5 are all hollow cylindrical with openings at both ends. The left discharge pipe 3 and the right discharge pipe 5 are respectively located on the left and right sides of the middle discharge pipe 4, and are respectively arranged obliquely downward in a direction away from the middle discharge pipe 4.

[0021] See also Figure 1 , Figure 2 In one embodiment, a mounting frame 12 is further included. The mounting frame 12 is fixed on the ground beside the drop tube 2. A slide groove 13 is fixed on the mounting frame 12 in a direction parallel to the sliding direction of the drop tube 2. A slider 6 is fixed on the drop tube 2 by welding, and the slider 6 is slidably connected to the slide groove 13, so that the sliding effect of the drop tube 2 is more stable. Preferably, the cross-sections of the slide groove 13 and the slider 6 are both "convex" shaped. Such a configuration can further improve the sliding stability.

[0022] See also Figure 1The hydraulic push rod 8 is fixed on the mounting frame 12 by welding, and its telescopic rod is fixedly connected to the drop tube 2 by welding, so as to push the drop tube 2 to slide in the horizontal direction, so that the left discharge tube 3, the middle discharge tube 4, and the right discharge tube 5 can reach the feed tube 1 respectively as they slide, so as to realize the diversion of materials.

[0023] See also Figure 2 , Figure 3 , Figure 4 A scraper assembly 9 is respectively provided in the left discharge pipe 3 and the right discharge pipe 5, and each of the scraper assembly 9 includes a scraper 10 and a drive motor 11. The scraper 10 rotates in the left discharge pipe 3 or the right discharge pipe 5, and its rotating shaft is along the central axis of the left discharge pipe 3 or the right discharge pipe 5 where it is located. In the process of rotation, the side of the scraper 10 away from its rotating shaft always keeps in contact with the inner wall to scrape off the sticky material on the inner wall. Since the inner wall of the middle discharge pipe 4 is vertical, the material is difficult to stick, so there is no need to set the scraper assembly 9 in the middle discharge pipe 4.

[0024] See also Figure 4 , the driving motor 11 is arranged in the left discharge pipe 3 or the right discharge pipe 5, and is used to drive the scraper 10 to rotate. In one embodiment, a support frame 14 is fixedly provided in the left discharge pipe 3 and the right discharge pipe 5 by welding, and is used to provide an installation position for the driving motor 11. The housing of the driving motor 11 is fixedly connected to the support frame 14 by welding, and the output shaft of the driving motor 11 is fixedly connected to the rotating shaft of the scraper 10 by welding. Such an arrangement has a more reasonable structure and a stable effect.

[0025] See also Figure 4 In one embodiment, the scraper 10 is in an "L" shape. This arrangement makes the structure more reasonable and easier to drive.
