DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: an anti-blocking hopper, in this embodiment, such as Figure 1 and Figure 2 As shown, a telescopic rod 9 is screwed between the outer barrel 3 and the hopper 7. The telescopic rod 9 is composed of a sleeve and a sliding rod inserted in a sliding manner with the sleeve. A spring 8 is sleeved on the outer side of the telescopic rod 9. The two ends of the spring 8 are screwed to the outer barrel 3 and the hopper 7 respectively. A plurality of push rods 5 are bolted to the outer barrel 3. The number of push rods 5 is the same as that of the cam 204 and they correspond to each other. The push rods 5 are parallel to the direction of the telescopic rod 9. The push rod 5 is a round rod structure with a roller head rotatably set at one end. A vibration mechanism 2 is set on one side of the outer barrel 3 to drive the push rod 5. A discharge pipe 11 is installed at the lower end of the hopper 7. A rotating shaft is rotatably set inside the discharge pipe 11. A material dividing plate 4 is arranged on the rotating shaft. A motor is installed on the outer side of the discharge pipe 11. Ⅱ10, the output end of the motor Ⅱ10 is connected to the shaft flange. Through the arrangement of the telescopic rod 9 and the spring 8, when the vibration mechanism 2 drives the push rod 5 to push the hopper 7, the spring 8 will be stretched. When the vibration mechanism 2 is separated from the push rod 5, the hopper 7 will vibrate, which can speed up the discharge of materials in the hopper 7 and make it less likely to be blocked. Through the dividing plate 4 arranged in the discharge pipe 11, the dividing plate 4 is driven by the motor Ⅱ10 to rotate, so that the material between the dividing plates 4 is discharged from the discharge pipe 11 when it rotates to the bottom, so that the material discharged from the discharge pipe 11 each time can be the amount of material contained between the two dividing plates 4, thereby achieving the function of quantitative discharge of materials.

[0023] like Figure 2-4As shown, the vibration mechanism 2 includes a motor Ⅰ201 fixed by bolts on the front side of the outer barrel 3, and the output end of the motor Ⅰ201 is connected to a gear 205 by an interference key, and the gear 205 is meshed with a driving ring 202. A driving rod 203 is arranged on the upper end of the driving ring 202, and the driving rod 203 is meshed with an annular cam 204. During specific operation, the motor Ⅰ201 is started to drive the gear 205 to rotate, and the gear 205 drives the driving ring 202 to rotate, so that the driving rod 203 arranged on the driving ring 202 rotates synchronously with the driving ring 202, so that the cam 204 pushes the pushing rod 5, so as to achieve the purpose of pushing the hopper 7. Through the synchronous rotation of multiple cams 204 in different directions throughout the whole circle, the hopper 7 is continuously shaken, the speed of material discharge is accelerated, and the material in the hopper 7 is not easily blocked.

[0024] like Figure 3 As shown, a mounting frame 1 is installed on the lower side of the outer barrel 3, and a symmetrical slider 12 is installed on the side of the mounting frame 1 close to the cam 204. An annular groove is opened on one side of the cam 204, and a load-bearing surface of a plane bearing 13 is fixed in the annular groove by screws, and the slider 12 and the other load-bearing surface of the plane bearing 13 are fixed by screws; therefore, the cam 204 is supported by the rotation of the plane bearing 13, so that the cam 204 can stably rotate on the side of the slider 12.

[0025] like Figure 3 and Figure 5 As shown, bevel teeth 15 are arranged on the inner wall of the annular cam 204, and the driving rod 203 is meshed with the bevel teeth 15, wherein the bevel teeth 15 match the movement trajectory of the driving rod 203, so that when the driving ring 202 drives the driving rod 203 to move, the driving rod 203 can drive the cam 204 to rotate by pushing the bevel teeth 15.

[0026] More specifically, the size of the drive ring 202, the distance between adjacent drive rods 203, and the arc direction of adjacent bevel teeth 15 satisfy the following conditions: when the drive ring 202 rotates, the drive rod 203 pushes on the arc surface of the adjacent bevel teeth 15, and the cam 204 rotates due to the push-pull cooperation between the two. The process state is: when the top of the previous drive rod 203 is about to slip out from between the previous level of bevel teeth 15, the top of the next drive rod 203 initially enters between the next level of bevel teeth 15, and when the top of the previous drive rod 203 completely slips out from between the previous level of bevel teeth 15, the top of the next drive rod 203 completely enters between the next level of bevel teeth 15. By operating in this way, the cam 204 at each position can rotate around the whole circle.

[0027] like Figure 4 As shown, teeth 14 are arranged on the inner wall of the driving ring 202, and the gear 205 meshes with the teeth 14. When the motor I 201 drives the gear 205 to rotate, the gear 205 can drive the driving ring 202 to rotate on the mounting frame 1 by meshing with the teeth 14.

[0028] like Figure 1 As shown, the driving ring 202 is rotatably arranged on the mounting frame 1, and the motor I 201 is installed on the mounting frame 1.

[0029] like Figure 2 As shown, a material baffle plate 6 is installed on the top of the outer barrel 3. The material baffle plate 6 is arranged above the hopper 7. When adding materials into the hopper 7 and when the hopper 7 vibrates, the materials can be prevented from falling into the outer barrel 3.

[0030] The utility model provides an anti-clogging hopper, and the specific working principle is as follows: during specific operation, the vibration mechanism 2 is started, so that the vibration mechanism 2 drives the push rod 5 to slide on the outer barrel 3, so that the push rod 5 pushes the hopper 7, and the hopper 7 is pushed by the push rod 5 and the action of the spring 8 and the telescopic rod 9 to achieve shaking, so that the material inside the hopper 7 falls from the discharge pipe 11 during the vibration, which can prevent the material from being blocked in the hopper 7, and the motor II 10 drives the dividing plate 4 to rotate at a uniform speed, so that the dividing plate 4 can drive the material between the dividing plates 4 to fall from the discharge pipe 11, thereby realizing the function of quantitative discharge.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
