[0037] The striking mechanism 4 includes a swivel 41, the bottom of which is fixedly connected to a bracket 42, and the bracket 42 is arranged in a circular array along the central axis of the swivel 41. A vibration column 43 is provided at the bottom of the swivel 41, and the top of the vibration column 43 is fixedly connected to the bottom of the fixed disk 31 through a spring plate 44, and the bottom of the spring plate 44 is fixedly connected to the top of the vibration column 43. The outer wall of the vibration column 43 is in contact with the outer wall of the bracket 42. The vibration column 43 transmits the vibration force to the sliding ring 32 through the spring plate 44, thereby driving the vibration rod 36 to vibrate, and the outer wall of the bracket 42 is slidably connected to the inner wall of the fixed tube 7.

[0038] Working principle:

[0039] When in use, first place the fixing frame 2 on the ground, so that the fixing frame 2 fixes the storage barrel 1 on the ground, then pour the granular material into the storage barrel 1, and then connect the external air source to the quantitative mechanism 3, so that the external air source can flow into the quantitative mechanism 3, and the quantitative mechanism 3 quantitatively releases the amount of particles in the storage barrel 1, and the released granular material flows out of the quantitative mechanism 3 driven by the airflow. In the process of the granular material flowing from the storage barrel 1 to the quantitative mechanism 3, if blockage occurs and the granular material cannot pass through the quantitative mechanism 3, the striking mechanism 4 can be rotated to vibrate the vibration rod 36 in the quantitative mechanism 3, so that the vibration rod 36 vibrates the granular material, thereby solving the blockage problem, and the anti-blocking mechanism 5 is used to assist in clearing the blockage.

[0040] The granular material moves downward from the storage barrel 1 under the action of gravity, and thus moves into the limiting ring 33, and a fixing block 38 is provided in the limiting ring 33, and the fixing block 38 is fixed to the fixing cylinder 7 through a connecting frame 37, so as to support the position of the fixing block 38, so that the granular material is blocked from moving downward, and a tension spring 35 and a resistance rod 34 are arranged on the fixing plate 31, so that under the action of the tension spring 35 and the resistance rod 34, the fixing plate 31 has a supporting force, but when the granular material accumulates more and more, the weight of the granular material is greater than the supporting force of the tension spring 35 and the resistance rod 34, so that the limiting ring 33 is provided with a fixing block 38, and the fixing block 38 is fixed to the fixing cylinder 7 through a connecting frame 37, so as to support the position of the fixing block 38, so that the granular material is blocked from moving downward, and the fixing plate 31 is blocked with a tension spring 35 and a resistance rod 34, so that the fixing plate 31 has a supporting force, and when the granular material accumulates more and more, the weight of the granular material is greater than the supporting force of the tension spring 35 and the resistance rod 34, so that the limiting ring 33 is provided with a fixing block 38, and the fixing plate 31 is provided with a fixing plate 31 ... The ring 33 moves downward, thereby causing the limit ring 33 and the fixed block 38 to be offset, so that the granular material can move downward from the gap in the offset, and the granular material moving downward moves to the conveying shell 52 through the bellows 39, and can be transported to the outside through the airflow. A limit ring 33 is provided in the fixed cylinder 7. The limit ring 33 blocks the granular material on the top of the sliding ring 32 during the downward movement of the sliding ring 32. After the weight of the granular material in the limit ring 33 is reduced and is not enough to withstand the supporting force of the tension spring 35 and the resistance rod 34, the limit ring 33 moves upward, thereby resetting, and can block the movement of the granular material again.

[0041] When the granular material is blocked while passing through the quantitative mechanism 3, the blocked granular material can be cleared by the striking mechanism 4. It is only necessary to reciprocate the rotating ring 41 to drive the bracket 42 to move synchronously through the rotating ring 41. During the movement, the bracket 42 reciprocates and hits the vibration column 43. Because the vibration column 43 is fixed to the fixed disk 31 through the spring plate 44, when the vibration column 43 vibrates, the vibration is synchronously transmitted to the fixed disk 31 through the spring plate 44, thereby causing the fixed disk 31 to vibrate, thereby driving the vibration rod 36 on the sliding ring 32 to vibrate synchronously. Through the vibration of the vibration rod 36, the granular material is dispersed, thereby solving the problem of granular material blockage.

[0042] In addition, an air outlet pipe 53 is fixed on the sliding ring 32. Therefore, after the airflow in the external air source enters the conveying shell 52, part of the airflow enters the air outlet pipe 53 through the air inlet pipe 51, and then blows into the sliding ring 32 through the air outlet pipe 53, thereby blowing away the granular material, thereby preventing the granular material from being accumulated and compacted and causing blockage.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
