[0030] In a preferred embodiment, please refer to Figure 7The vibration anti-blocking component 300 includes a wave wheel 301 and multiple end frames 303. A conical gear ring 302 is fixedly provided on the top of the wave wheel 301, and a toggle rod 304 is rotatably provided at the bottom of the end frame 303.

Through the tightening of the return spring 306, the toggle rod 304 resists the concave and convex edges of the outer periphery of the wave wheel 301.

[0031] In a preferred embodiment, please refer to Figure 8 The boost anti-blocking assembly 400 includes a boost cylinder 401, a one-way valve 408 is arranged on the air outlet pipe 409 at the bottom of the boost cylinder 401, and a boost shaft 406 is rotatably arranged on the top of the boost cylinder 401, a fourth pulley 405 is fixedly arranged on one end of the boost shaft 406, and a linkage arm 403 is rotatably arranged on the middle of the boost shaft 406 through a crank arm 404, a boost piston 407 is rotatably arranged at the bottom of the linkage arm 403, and a one-way valve 408 is arranged on the boost piston 407 The air inlet pipe 402, the bottom of the boost cylinder 401 is fixed on the top of the discharge pipe 114, and a belt 106 is sleeved between the third pulley 111 and the fourth pulley 405. The boost shaft 406 drives the boost piston 407 to reciprocate up and down in the boost cylinder 401 through the crank arm 404 and the linkage arm 403. At this time, the external air enters the boost cylinder 401 unidirectionally through the air inlet pipe 402, and the air in the boost cylinder 401 enters the top of the discharge pipe 114 unidirectionally through the air outlet pipe 409.

[0032] In summary, in actual use, the fertilization outer frame assembly 100 is fixed at the reserved position by bolts. At this time, the feed pipe 113 is connected to the external fertilizer delivery device. The fertilizer delivery device is a prior art, so it is not repeated. In actual use, the external fertilizer is continuously delivered to the discharge pipe 114 through the feed pipe 113. At this time, the drive motor 104 is started, and the drive motor 104 drives the quota storage inner wheel 201 to rotate through the drive shaft 105. At this time, the multiple quota storage grooves 202 on the quota storage inner wheel 201 rotate in the fertilization outer frame 101. During the rotation process, the quota storage groove 202 at the top receives the fertilizer at the discharge pipe 114, and then rotates to the discharge pipe 118 to discharge the fertilizer. In this process, the capacity of the quota storage groove 202 is constant, and the quota fertilizer can be taken through the quota storage groove 202. During the rotation process, rapid loading and unloading of fertilizer can be achieved.

[0033] On the basis of the above, that is, during the rotation of the quota storage inner wheel 201, a stirring shaft 203 is rotatably arranged inside each quota storage slot 202. When the quota storage inner wheel 201 is in the rotational fast loading and fast unloading, the driven gear 204 arranged at each quota storage slot 202 is meshed and moved on the periphery of the fixed gear 207. In this way, when the quota storage inner wheel 201 rotates to load and unload, the stirring shaft 203 rotates in the quota storage slot 202. Through this follow-up rotation, the stirring support arm 206 and the scraping end plate 205 are rotated and stirred in the quota storage slot 202. In this way, on the one hand, the fertilizer inside the quota storage slot 202 can be quickly dropped when fertilizer is added, and on the other hand, the fertilizer can be prevented from caking and clogging on the inner wall of the quota storage slot 202, and the unloading can be prevented from being fast and thorough, thereby avoiding the deviation of the quota fertilizer addition.

[0034] On the basis of the above, in order to ensure that the fertilizer at the feeding pipe 114 can smoothly enter the quota storage tank 202, when the driving motor 104 of the present invention is started, the first pulley 103 on the driving shaft 105 drives the second pulley 108 to rotate through the belt 106, and at this time the third pulley 111 drives the boost shaft 406 to rotate through the belt 106 and the fourth pulley 405. When the driving motor 104 is started, the boost shaft 406 also rotates synchronously. At this time, the boost shaft 406 drives the boost piston 407 to move up and down in the boost cylinder 401 through the crank arm 404 and the linkage arm 403. When the boost piston 407 moves upward in the boost cylinder 401, the external air passes through the intake pipe 40 2 and the one-way valve 408 enter the boost cylinder 401 in one direction. When the boost piston 407 moves downward in the boost cylinder 401, the air in the boost cylinder 401 is squeezed and enters the discharge pipe 114 in one direction through the air outlet pipe 409 and the one-way valve 408. At this time, a downward blowing structure is formed on the top of the discharge pipe 114. By blowing air downward, it can be ensured that the fertilizer at the bottom of the discharge pipe 114 can smoothly fall into the quota storage tank 202, that is, air supply-assisted fertilizer feeding is realized. At the same time, in this process, due to the air supply, a micro-pressure environment is formed on the top of the discharge pipe 114. Through this micro-pressure environment, it is further ensured that the fertilizer at the bottom of the discharge pipe 114 falls into the quota storage tank 202, further forming an anti-blocking structure to avoid fertilizer blockage.

[0035] On the basis of the above, a pressure relief pipe 112 is provided at the top of the feed pipe 114. In order to avoid excessive pressure in the feed pipe 114, which affects the fertilizer from falling into the quota storage tank 202, when the pressure in the feed pipe 114 is too high, the high pressure will overcome the pushing force of the tightening spring 122, and push the sealing piston 123 to the position of the perforated inner disk 120. At this time, the sealing piston 123 will release the blockage of the pressure relief groove 119. At this time, the high-pressure gas inside the feed pipe 114 will be discharged in time through the pressure relief groove 119. Through this structure, the inside of the feed pipe 114 is always in a micro-pressure environment, avoiding excessive pressure that affects the feeding of the feed pipe 113 into the feed pipe 114.

[0036] On the basis of the above, in order to further avoid the accumulation and blockage of fertilizer at the bottom of the discharge pipe 114, when the driving motor 104 is started, the support shaft 109 rotates synchronously. At this time, the bevel gear 110 on the support shaft 109 drives the wave wheel 301 to rotate around the fixed platform 116 through the bevel gear ring 302. At this time, the protrusion on the edge of the wave wheel 301 will have an outward pushing force on the toggle rod 304. At this time, the resisting rubber ball head 307 will compress the reset spring 306 and move away from the barrel of the discharge pipe 114. As the wave wheel 301 continues to rotate, the toggle rod 304 will quickly fall into the groove on the edge of the wave wheel 301. At this time, through the reset of the reset spring 306, the resisting rubber ball head 307 will form an impact action on the barrel of the discharge pipe 114. Through this knocking structure, the smooth discharge of fertilizer at the discharge pipe 114 is further achieved, thereby further avoiding the blockage of fertilizer.

[0037] Generally speaking, during the rotation of the inner wheel assembly 200 of fertilizing, the quota material receiving and quota material discharge of the quota material storage tank 202 are realized, and at the same time, during the rotation, the internal follow-up stirring of the quota material storage tank 202 is realized, so as to avoid the compaction and blockage of the fertilizer in the quota material storage tank 202, and at the same time, ensure the rapid discharge of the fertilizer in the quota material storage tank 202. This is a primary anti-blocking mechanism. During the rotation of the inner wheel assembly 200 of fertilizing, a follow-up air supply auxiliary fertilizer discharge structure and a micro-pressure auxiliary fertilizer discharge structure are arranged on the top of the discharge pipe 114. Through this structure, secondary anti-blocking is realized, and the smoothness of fertilizer discharge is ensured. At the same time, During the rotation of the fertilizing inner wheel assembly 200, the corrugated wheel 301 continuously rotates with it, so that the rubber ball head 307 is pushed outward and reset inward, thereby realizing the anti-blocking knocking of the rubber ball head 307 on the discharge pipe 114. Through this structure, three-level anti-blocking is realized. The second-level anti-blocking and the third-level anti-blocking are realized on the basis of the first-level anti-blocking operation. The second-level anti-blocking and the third-level anti-blocking are realized with it and synchronously, and do not require additional power to participate in the realization of follow-up and synchronization. Through the cooperation of the above-mentioned structure, on the basis of ensuring the quota discharge of fertilizer, the anti-blocking discharge of fertilizer is also realized.
