[0023] Example 1

[0024] like Figure 1-4 As shown, a blast furnace distributor comprises a distributor body 1, a rotating ring 2, a driving sleeve 3 and a distribution trough 201. The lower part of the distributor body 1 is a semi-conical structure. By setting the lower part of the distributor body 1 as a semi-conical structure, the coal can be more converged when falling into the distribution trough 201, so as to prevent the coal from being impacted and scattered, thereby affecting the distribution effect. The bottom surface of the distributor body 1 is connected to and fixed with a discharge barrel 101. The drive sleeve 3 is fixedly arranged on the outer side of the discharge barrel 101 of the distributor body 1. The rotating ring 2 is rotatably connected to the lower part of the discharge barrel 101 through a bearing. A driving mechanism is arranged between the discharge barrel 101 and the driving sleeve 3. The driving mechanism controls the rotation of the rotating ring 2. Figure 3As shown, the driving mechanism includes a driving motor, which is installed on the discharge barrel 101. The output shaft of the driving motor is vertically downwardly arranged and a driving gear (not shown in the figure) is fixed at the end. A driven gear is fixed on the top surface of the rotating ring 2. The driving gear of the driving motor is meshed with the driven gear on the top surface of the rotating ring 2. Through the above technical solution, the driving gear is driven to rotate by the driving motor, and the rotating ring 2 is driven to rotate under the meshing action of the driving gear and the driven gear on the top surface of the rotating ring 2. A material distributing trough 201 is provided below the rotating ring 2, and the material distributing trough 201 rotates synchronously with the rotating ring 2, and one end of the material distributing trough 201 is hinged to the bottom of the rotating ring 2; a slidable connecting frame 301 is provided on the outer wall of the driving sleeve 3, and two engaging holes 302 are provided on the outer wall of the driving sleeve 3, and a engaging groove is provided on the inner side of the connecting frame 301, and the engaging hole 302 is slidably engaged with the engaging hole 302 of the driving sleeve 3 through the engaging groove, one end of the connecting rod mechanism is connected to the connecting frame 301, and the other end of the connecting rod mechanism is connected to one end of the material distributing trough 201, and the lifting mechanism controls the lifting and lowering of the connecting frame 301, and the connecting frame 301 drives one end of the material distributing trough 201 to lift and lower along the hinge through the connecting rod mechanism, thereby controlling the material distributing angle of the material distributing trough 201.

[0025] Through the above technical solution, the material in the distributor body 1 flows out from the distribution trough 201 through the discharge barrel 101, and the driving mechanism is turned on when rotary distribution is performed, so that the driving mechanism drives the rotating ring 2 to rotate, thereby driving the lower distribution trough 201 to rotate synchronously to realize rotary distribution, and the lifting and lowering of the connecting frame 301 is controlled by the lifting mechanism, and the lifting and lowering of one end of the distribution trough 201 is controlled by the connecting rod mechanism, thereby controlling the inclination angle of the distribution trough 201, realizing the change of the distribution speed, and thus there is no need to manually adjust the distribution speed, and the rotary distribution of the distribution trough 201 can achieve better distribution effect.

[0026] A further solution of the present invention is that: Figure 3 As shown, the lifting mechanism includes two electric push rods 102, the push rods of the two electric push rods 102 are arranged vertically downward, the two electric push rods 102 are installed on the inner wall of the driving sleeve 3, one end of the telescopic rod of the two electric push rods 102 is fixed to the top surface of the connecting frame 301, and the connecting frame 301 is driven to rise and fall by the electric push rods 102 so that the inclination angle of the cloth trough 201 changes.

[0027] like Figure 2As shown, the connecting rod mechanism includes a linkage rod 203, one end of which is connected to the connecting frame 301, and the other end of the linkage rod 203 is rotatably connected to a connecting block 202. One end of the material distributing trough 201 is hinged to a rotating seat 207, and the rotating seat 207 is fixedly connected to the bottom of the rotating ring 2. The connecting block 202 is fixedly connected to one end of the material distributing trough 201, and the other end of the linkage rod 203 is fixedly connected to one end of the material distributing trough 201 through the connecting block 202. When the linkage rod 203 is lifted or lowered, the connecting block 202 drives one end of the material distributing trough 201 to rotate and lift, thereby controlling the inclination angle of the material distributing trough 201.

[0028] Example 2

[0029] This embodiment is based on the implementation of embodiment 1, and the further technical solution is:

[0030] like Figure 2 As shown, the outer wall of the connecting frame 301 is provided with a continuous wavy arc groove 303, and one end of the linkage rod 203 is provided with a clamping block 204, and the clamping block 204 is slidably clamped with the inside of the arc groove 303. Through the above technical solution, when the rotating ring 2 rotates or drives the clamping block 204 to slide inside the arc groove 303, the material distribution trough 201 is driven by the rotating ring 2 to rotate while shaking up and down, thereby preventing the coal from piling up on the material distribution trough 201. Two limiting rods 205 are fixed to the outer wall of the rotating ring 2, and a sliding hole 206 is provided on one side of the linkage rod 203. The limiting rod 205 is slidably clamped with the inside of the sliding hole 206. The two limiting rods 205 can limit the linkage rod 203 to prevent the clamping block 204 on the linkage rod 203 from being separated from the arc groove 303.

[0031] How it works:

[0032] According to the above embodiment, when in use, by starting the driving motor, the driving gear of the driving motor meshes with the driven gear on the top surface of the rotating ring 2, so that the rotating ring 2 is driven to rotate, and when the rotating ring 2 rotates, the material distributing trough 201 is driven to rotate, and the rotating material distributing trough 201 can achieve a better material distributing effect. When the material distributing trough 201 rotates, since the material distributing trough 201 and the rotating ring 2 are in a synchronous rotation connection, the material distributing trough 201 can rotate relative to the bottom surface of the rotating ring 2. At the same time, the connecting block 202 is fixed to one side of the material distributing trough 201, and the connecting block 202 is rotatably connected to the linkage rod 203. When the linkage rod 203 is connected, When the connecting frame 301 is lifted or lowered, the connecting block 202 is pressed down or pulled up, so that the material distributing groove 201 rotates along the rotating seat 207. Since the clamping block 204 on the linkage rod 203 is slidably engaged with the inside of the arc groove 303, when the linkage rod 203 drives the clamping block 204 to slide inside the arc groove 303, due to the continuous wave-like arc structure of the arc groove 303, the linkage rod 203 moves up and down continuously, thereby realizing the vibration of the material distributing groove 201. The electric push rod 102 drives the connecting frame 301 to lift and lower, which can greatly raise or lower the position of the linkage rod 203, so that the material distributing groove 201 is greatly tilted, thereby realizing the change of the material distributing speed.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
