Referring to fig. 1 and 2 together, according to the utility model discloses an edulcoration mechanism for coal transportation includes coal conveying device 1, link assembly 2 and shift fork 3. Wherein, coal conveyor 1 locates the pouring opening below coal 4, and coal 4 is transported and is transported by coal conveyor 1 after toppling over. The connecting rod assembly 2 is fixedly arranged on the coal conveying device 1, and the connecting rod assembly 2 and the coal conveying device 1 are kept relatively static. The shifting fork 3 is movably connected with the connecting rod assembly 2, and when the coal conveying device 1 starts to convey coal 4, the shifting fork 3 swings on the coal conveying device 1 so as to filter sundries in the coal on the coal conveying device 1.

In particular, the connecting-rod assembly 2 comprises a mounting seat 21, a positioning rod 22, a cross-bar 24 and a sleeve 23. Wherein, each mounting seat 21 is respectively fixed on the frame 11 at one side of the coal conveying device 1, and each positioning rod 22 is detachably fixed in one mounting seat 21. The outer peripheral surface of sleeve 23 and shift fork 3 fixed connection, sleeve 23 endotheca is equipped with horizontal pole 24, and horizontal pole 24 is fixed to be located between two locating levers 22. Preferably, in the present embodiment, the sleeve 23 is movable on the shaft of the crossbar 24, and both ends of the crossbar 24 are fixedly connected to one positioning rod 22 respectively. When the coal conveying device 1 operates, the impurity removing position of the shifting fork 3 can be calibrated through the movable sleeve 23. In the present embodiment, the coal conveying apparatus 1 includes, but is not limited to, a belt conveyor or the like that conveys coal by a belt.

Preferably, the outer circumferential surfaces of both sides of the sleeve 23 are provided with a limiting groove 231, and the outer circumferential surfaces of both sides of the cross bar 24 are provided with a limiting post 241. Wherein, the limiting column 241 is located in the limiting groove 231 and penetrates out of the limiting groove 231. When the shifting fork 3 swings to the maximum set angle, one side of each limiting groove 231 is abutted to the corresponding limiting column 241, so that the shifting fork 3 is limited to swing, and the shifting fork 3 is supported to filter out impurities on coal 4. In the present embodiment, the notch of each stopper groove 231 is disposed toward the belt.

Specifically, the fork 3 includes a fork rod 31 and a fork 32. Wherein, one end of the fork rod 31 is fixedly connected with the peripheral surface of the sleeve 23, and the other end of the fork rod 31 is provided with a plurality of fork teeth 32 which are arranged at intervals. Preferably, in this embodiment, each prong 32 has a different length, gradually decreasing from the middle to the sides. When the coal conveying device 1 runs, the belt 12 is in an arch shape with a low middle part and high two sides, and the coal 4 is unevenly distributed on the belt 12. When the coal conveying device 1 is in operation, sundries in the coal are blocked by the plurality of fork teeth 32 with different lengths so as to be filtered.

Further, a torsion sensor is provided in the sleeve 23. The torque sensor monitors the bearing condition of the shifting fork 3 in real time and generates a bearing signal to be transmitted into the coal conveying device 1. When the fork teeth 32 of the shifting fork 3 block excessive sundries, the coal conveying device 1 stops running, thereby avoiding the shifting fork 3 from being damaged due to the excessive sundries.

To sum up, the utility model discloses a shift fork that the activity set up on the coal conveyor carries out the filtering to debris in the coal to coal has been solved convenient and fast ground and has been got rid of loaded down with trivial details problem in the transportation debris. Furthermore, the fork teeth with different lengths on the shifting fork are matched with coal which is unevenly distributed on the belt, so that the shifting fork can more accurately filter out sundries in the coal. Furthermore, a torsion sensor arranged in the sleeve is coupled with the coal conveying device, and the torsion sensor monitors the bearing condition of the shifting fork at any time, so that the shifting fork is prevented from being damaged due to excessive bearing of sundries. Furthermore, the limiting columns on the cross rods are matched with the limiting grooves in the sleeves, so that the swing amplitude of the shifting fork is limited, and then the shifting fork is supported to filter out sundries in coal.
