[0023] See also Figure 1-4 , an embodiment provided by the utility model:

[0024] The box body 1, movable groove 11, discharge pipe 12, bearing 13 and propeller 14 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here.

[0025] A material blocking mechanism for a screw conveyor comprises: a box body 1, a material discharging pipe 12 is installed on the bottom surface of the box body 1, and a propeller 14 is movably installed on the box body 1 through a bearing 13;

[0026] A movable groove 11 is provided on the inner wall of the box body 1, and a positioning groove 15 is provided on the right end surface of the propeller 14;

[0027] A material blocking structure 2 is installed on the inner side of the box body 1, and the material blocking structure 2 includes a material blocking plate 21, which is sleeved on the right end surface of the propeller 14, and a mounting groove 22 is opened on the surface of the material blocking plate 21. A fixing block 23 is installed on the inner side of the mounting groove 22. An external threaded sleeve 24 is welded on the right side wall of the material blocking plate 21 and the fixing block 23, and a positioning block 25 is welded on the inner wall of the external threaded sleeve 24. Two groups of internal threaded sleeves 26 are sleeved on the outer side of the right end of the propeller 14, and the two groups of internal threaded sleeves 26 are fixedly connected by threaded rods 27. Next, a conical groove 28 is provided on the left side wall of the baffle plate 21 and the fixed block 23. By arranging the baffle structure 2 on the upper side of the discharge pipe 12, when the baffle structure 2 blocks the material, the material can be located on the upper side of the discharge pipe 12, which is convenient for the material to be discharged through the discharge pipe 12. The conical groove 28 is provided on the baffle plate 21 and the fixed block 23, which can guide the material to move in the opposite direction from the upper end, avoiding the material from accumulating on the surface of the baffle plate 21 and the fixed block 23 and then being scattered, thereby ensuring the material transportation experience and improving practicality.

[0028] Furthermore, the movable groove 11 is located on the upper side of the discharge pipe 12 , and the material blocking plate 21 and the fixed block 23 installed on the inner side of the movable groove 11 can block the material from moving to the right, and the blocked material can be quickly discharged through the discharge pipe 12 .

[0029] Furthermore, the surfaces of the baffle plate 21 and the fixed block 23 are flush, and one end of the baffle plate 21 and the fixed block 23 are located inside the movable groove 11 . The baffle plate 21 cooperates with the fixed block 23 to prevent the material from moving to the right.

[0030] Furthermore, the two sets of external threaded sleeves 24 are both sleeved on the outside of the propeller 14 , and the positioning block 25 is stuck in the inside of the positioning groove 15 . The positioning block 25 provides a limit for the installation of the baffle plate 21 and the fixing block 23 on the propeller 14 .

[0031] Furthermore, the two groups of internal threaded sleeves 26 are movably installed on the outer walls of the two groups of external threaded sleeves 24 through threads, and the two groups of external threaded sleeves 24 can be fixed to the propeller 14 through the internal threaded sleeves 26, so that the assembly between the fixing block 23 and the baffle plate 21 is stable.

[0032] Furthermore, the conical groove 28 is conical, and the surface of the conical groove 28 fits the inner wall of the movable groove 11. When in use, the conical groove 28 can guide the material to move to the left from its edge, preventing the material from accumulating on the surface of the baffle plate 21 and the fixed block 23 and then spilling out.

[0033] Working principle: During installation, the mounting groove 22 is facing downward, and the baffle plate 21 can be installed on the surface of the propeller 14. The positioning block 25 on the baffle plate 21 can be stuck in the inside of the positioning groove 15. Then the propeller 14 is rotated, and the propeller 14 drives the baffle plate 21 to rotate. The baffle plate 21 can be rotated to the lower side of the propeller 14. At this time, the mounting groove 22 is facing upward, and the fixing block 23 is lowered into the mounting groove 22. The positioning block 25 on the fixing block 23 is stuck in the positioning groove 15. The baffle plate 21 cooperates with the mounting groove 22 to form a disc shape, and the two sets of external threaded sleeves 24 fit each other to form a cylindrical shape.

[0034] The two sets of internal thread sleeves 26 are respectively sleeved on both sides of the right end of the propeller 14, and are connected and fixed by the internal thread sleeves 26. The two sets of internal thread sleeves 26 can form a cylindrical shape. Then, the two sets of internal thread sleeves 26 are screwed on the surfaces of the two sets of external thread sleeves 24, and the fixed block 23 and the baffle plate 21 can be fixed. The edges of the baffle plate 21 and the fixed block 23 are located in the movable groove 11, and the conical groove 28 contacts the inner wall of the movable groove 11. The baffle plate 21 and the fixed block 23 can prevent the material from continuing to move to the right. The movement can ensure the smoothness of the bearing 13, and the setting of the tapered groove 28 can guide the material to move to the left from the edge of the tapered groove 28, to prevent the material from accumulating and then spilling out from the surface of the baffle plate 21 and the fixed block 23. At the same time, the baffle plate 21 and the fixed block 23 are located on the upper side of the discharge pipe 12. After the discharge pipe 12 and the fixed block 23 block the material, the material can be discharged downward through the discharge pipe 12, which can ensure that the material is quickly and completely discharged from the box body 1, which can ensure the material transportation experience and improve practicality.
