[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: This embodiment is used to solve the problem that when a conventional disc coal dispensing is blocked, it is inconvenient to clear the blockage in time and it is difficult to achieve fast and effective material discharging processing.

[0029] See also Figure 1-Figure 7 As shown, this embodiment is an anti-blocking disc coal distribution assembly based on uniform feeding, comprising a turntable 1 supported by a frame, a rotating shaft 3 is coaxially fixedly connected to the lower surface of the turntable 1, a silo 2 supported by an external frame is arranged on the top of the turntable 1, a feeding cylinder 5 is arranged on the top of the silo 2, and a blocking removal mechanism is arranged in the silo 2;

[0030] The unblocking mechanism includes a lower barrel 4 fixedly connected to the bottom end of the feed barrel 5, and a lifting barrel 9 sleeved on the outer wall of the lower barrel 4 is provided in the silo 2. The lifting barrel 9 moves vertically upward to discharge the large pieces of coal accumulated on the inner wall of the lifting barrel 9. A discharging mechanism is provided in the silo 2;

[0031] The discharging mechanism includes a push rod 22 rotatably connected to one side of the silo 2, a movable connecting head is fixedly connected to the inner wall of the silo 2, and a pin is rotatably connected to the push rod 22 through a movable connection, a mounting box 21 is fixedly connected to the inner wall of the silo 2, a rotating disk 18 is rotatably connected to the lower surface of the mounting box 21, and the rotating disk 18 is movably connected to a movable rod 19 through a rotating shaft, and one end of the movable rod 19 away from the rotating shaft is fixedly connected to a connecting rod 20, and one end of the connecting rod 20 away from the movable rod 19 is fixedly connected to the push rod 22;

[0032] When the rotating disk 18 rotates, the rotating disk 18 pushes the movable rod 19 back and forth, and pushes the pushing rod 22 through the movable rod 19 and the connecting rod 20, so that the pushing rod 22 can swing back and forth on the upper surface of the turntable 1. When blockage occurs, the lifting cylinder 9 is moved in the vertical direction to facilitate the discharge of larger lumps of coal in the lifting cylinder 9, and the reciprocating swing of the pushing rod 22 can quickly separate the larger lumps of coal from the bottom of the lifting cylinder 9, thereby realizing rapid discharge processing.

[0033] The lifting cylinder 9 is located on the inner and outer walls of the silo 2 and is fixedly connected with two symmetrically arranged connecting rods 27. The upper surfaces of the two connecting rods 27 are fixedly connected with limiting rods 12. The upper surface of the silo 2 is fixedly connected with a cover plate 14. The limiting rods 12 penetrate the cover plate 14 and are vertically slidably connected to the cover plate 14. The limiting rods 12 limit the lifting cylinder 9 in the vertical direction to ensure that the discharge port 8 can move stably in the vertical direction.

[0034] The unloading barrel 4 penetrates and is vertically slidably connected with a connecting frame 11. The lower surface of the connecting frame 11 is fixedly connected to the limit rod 12. A hydraulic rod 13 is fixedly installed on the upper surface of the cover plate 14. A connecting plate 10 is fixedly connected to one side of the connecting frame 11. The telescopic end of the hydraulic rod 13 is fixedly connected to the lower surface of the connecting plate 10. When the hydraulic rod 13 is started, the hydraulic rod 13 pushes the connecting plate 10, which can push the connecting frame 11 vertically upward and push the lifting barrel 9 to move vertically upward, thereby quickly solving the problem of material blockage.

[0035] A worm wheel 24 is rotatably connected to the fixed axis in the installation box 21, and the connecting shaft of the worm wheel 24 is coaxially fixedly connected to the rotating disk 18. A worm 25 meshing with the worm wheel 24 is rotatably connected to the fixed axis in the installation box 21. A connecting frame 23 is fixedly installed on one side of the outer wall of the silo 2, and a motor 1 26 is fixedly installed on the connecting frame 23. The output shaft of the motor 1 26 passes through the silo 2 and is fixedly connected to the worm 25.

[0036] The starting motor 26 drives the worm 25 to rotate. The worm 25 and the motor 26 cooperate to withstand a large torque and load, and can rotate the rotating disk 18 coaxially fixedly connected to the worm wheel 24. The rotating disk 18 rotates to push the movable rod 19, and the movable rod 19 and the connecting rod 20 reciprocate to push the pushing rod 22 to swing back and forth in the silo 2, thereby accelerating the discharge of the blocked coal in the silo 2.

[0037] Embodiment 2: This embodiment is used to solve the problem of stable and orderly transportation of coal.

[0038] See also Figure 1-Figure 7 As shown, in the anti-blocking disc coal blending assembly based on uniform feeding of this embodiment, a discharge port 8 is arranged on one side of the outer wall of the connecting plate 10, a conveying platform 6 is arranged on one side of the bottom of the discharge port 8, and a horizontally arranged conveying belt 7 is arranged on the inner side of the conveying platform 6. The conveying belt 7 is located on one side of the bottom of the discharge port 8. The rotating shaft 3 is driven to rotate by a reducer, and the rotating shaft 3 is rotated by reducing the speed to drive the turntable 1 to rotate, so that the coal is discharged from the bottom side of the discharge port 8, so as to realize the batching and conveying of the materials in the silo 2, and ensure the uniform and stable transportation of the coal.

[0039] A guide plate 15 is movably connected to one side of the silo 2 near the discharge port 8. The guide plate 15 is rotatably connected to one side of the inner wall of the discharge port 8 through a pin shaft. As the turntable 1 rotates, the coal on the turntable 1 contacts the guide plate 15 and moves along the surface of the guide plate 15 toward the discharge port 8, thereby evenly discharging the coal.

[0040] An opening is provided on one side of the outer wall of the silo 2, and a positioning plate 16 is fixedly connected to one side of the outer wall of the silo 2 near the opening. The guide plate 15 is movably connected to an adjusting rod 17 through a pin shaft. Positioning grooves are provided on the surfaces of the adjusting rod 17 and the positioning plate 16. The positioning grooves on the surface of the adjusting rod 17 are arranged at intervals, and the position of the adjusting rod 17 is positioned by inserting a pin into the positioning groove.

[0041] Combining the first and second embodiments, it can be seen that the blocking problem of coal in the feeding process can be effectively solved by setting the unblocking mechanism and the discharging mechanism, especially the cooperation between the lifting cylinder 9 and the push rod 22. The vertical movement of the lifting cylinder 9 can loosen and discharge the coal accumulated on the inner wall, and the reciprocating swing of the push rod 22 further ensures that the accumulated coal can quickly break away from the bottom of the lifting cylinder 9, thereby realizing fast and effective discharging processing.

[0042] The angle and position of the guide plate 15 can also be adjusted according to actual needs to further optimize the feeding effect and meet different production needs. The feeding barrel 5 and the discharge barrel 4 ensure that the coal can enter the silo 2 stably and evenly, which helps to reduce the fluctuation and accumulation of coal during the feeding process, realize stable and orderly transportation of coal, and improve the accuracy and stability of coal blending.

[0043] like Figure 1-Figure 7 As shown, the working process and principle of the present invention are as follows:

[0044] Step 1: When material blockage occurs, the hydraulic rod 13 is started to push the connecting plate 10, which can push the connecting frame 11 to move vertically upward. The connecting frame 11 pulls the limit rod 12 fixedly connected thereto, and pulls the connecting rod 27 fixedly connected thereto through the limit rod 12, pulls the lifting cylinder 9 to move in the vertical direction, and pushes the lifting cylinder 9 to move vertically upward. The motor 126 is started to drive the worm 25 to rotate, and the rotating disk 18 coaxially fixedly connected to the worm gear 24 rotates. The rotating disk 18 rotates to push the movable rod 19, and the push rod 22 is reciprocated through the movable rod 19 and the connecting rod 120 to swing back and forth in the silo 2, thereby accelerating the discharge of the blocked coal in the silo 2;

[0045] Step 2, push the adjusting rod 17 to move, the adjusting rod 17 moves in the opening of the outer wall of the silo 2, push the guide plate 15 to adjust the angle of the guide plate 15, insert the pin into the positioning groove to fix the position of the guide plate 15, the coal on the turntable 1 contacts the guide plate 15, and moves along the surface of the guide plate 15 toward the side of the discharge port 8, and the discharge port 8 discharges the material evenly onto the conveyor belt 7.
