[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1-2 The present invention relates to an anti-clogging hopper for grain feeding, comprising a feeding frame 1, a bottom frame 5 fixedly installed at the bottom of the feeding frame 1, a feeding frame 4 movably sleeved on the outside of the bottom frame 5, and an anti-clogging mechanism 2 and a stirring mechanism 3 provided on the bottom frame 5.

[0025] Specifically, by Figure 3The anti-blocking mechanism 2 includes an outer frame 201 fixed to the outside of the feed frame 1. Two L-shaped rods 2010 are symmetrically fixedly connected between the bottom of the outer frame 201 and the outside of the bottom frame 5. Both L-shaped rods 2010 are located above the discharge frame 4. Side frames 205 are movably sleeved on the outside of each L-shaped rod 2010, and both side frames 205 are fixed to the outside of the discharge frame 4. A support base 203 and a support plate 209 are symmetrically fixedly connected to the bottom of the outer frame 201. A rotary motor 204 is fixedly connected to the side of the support base 203 closest to the support plate 209. A drive shaft 207 is fixedly connected to the rotary motor 204. The end of the drive shaft 207 furthest from the rotary motor 204 is connected to the support plate 209. 09 Rotary connection, the drive shaft 207 passes through the bottom frame 5 and is rotatably connected to the bottom frame 5, and the drive shaft 207 is located above the feeding frame 4. Multiple stirring plates 202 located inside the bottom frame 5 are fixedly connected to both sides of the drive shaft 207. Reset springs 2011 are fixedly connected between the top of the two side frames 205 and the bottom of the outer frame 201. The two reset springs 2011 are respectively sleeved on the outside of the two L-shaped round rods 2010. Two eccentric blocks 208 are symmetrically fixedly sleeved on the outside of the drive shaft 207. The bottom frame 5 is located between the two eccentric blocks 208. Two top plates 206 are symmetrically fixedly connected to the top of the feeding frame 4. The two eccentric blocks 208 are respectively located directly above the two top plates 206.

[0026] In operation, the rotary motor 204 is first started, which drives the drive shaft 207 to rotate and drives each stirring plate 202 to rotate to stir the grain passing through the bottom frame 5, preventing the bottom frame 5 from getting blocked. At the same time, the rotation of the drive shaft 207 drives the two eccentric blocks 208 to rotate and impact the two top plates 206 respectively. Under the action of the elastic force of the two return springs 2011, the two side frames 205 reciprocate along the two L-shaped round rods 2010 respectively, so that the feeding frame 4 moves up and down continuously to prevent it from getting blocked. Finally, no manual cleaning is required.

[0027] Specifically, by Figure 4-5The stirring mechanism 3 includes an inner plate 301 fixed inside the bottom frame 5. An L-shaped frame 302 is fixedly installed at the bottom of the inner plate 301. A stirring shaft 304 is rotatably connected to the inner bottom wall of the L-shaped frame 302. Multiple stirring rods 303, all located within the feeding frame 4, are fixedly connected to the outer side of the stirring shaft 304. A driven bevel gear 308 is fixedly connected to the top of the stirring shaft 304. A driving bevel gear 307 is fixedly installed on the outer side of the transmission shaft 207, and the driving bevel gear 307 meshes with the driven bevel gear 308. A protective box 305 is fixedly installed on the outer side of the inner plate 301. A guide plate 306 is fixedly installed on the top. Both the guide plate 306 and the inner plate 301 are triangular plates, which serve to guide the flow and prevent the grain from falling on the top of the guide plate 306 and the inner plate 301. The drive shaft 207 and the stirring shaft 304 both pass through the protective box 305 and are rotatably connected to the protective box 305. The active bevel gear 307 and the driven bevel gear 308 are both located inside the protective box 305. By setting the protective box 305, the driven bevel gear 308 and the active bevel gear 307 are contained and protected, preventing the grain from falling onto the active bevel gear 307 and the driven bevel gear 308 and affecting normal operation.

[0028] In use, when the rotary motor 204 is started, it drives the transmission shaft 207 to rotate, which in turn drives the active bevel gear 307 to rotate. Since the active bevel gear 307 is meshed with the driven bevel gear 308, it drives the stirring shaft 304 to rotate. At the same time, each stirring rod 303 rotates to stir the grain passing through the feeding frame 4, which further improves the anti-clogging effect of the feeding frame 4.

[0029] Working principle: When grain is put into the feeding frame 1, the rotary motor 204 is started, which drives the transmission shaft 207 to rotate and drives each stirring plate 202 to rotate to stir the grain passing through the bottom frame 5, preventing the bottom frame 5 from getting blocked. At the same time, the rotation of the transmission shaft 207 drives the two eccentric blocks 208 to rotate and impact the two top plates 206 respectively. Under the action of the elastic force of the two return springs 2011, the two side frames 205 reciprocate along the two L-shaped round rods 2010 respectively, so that the feeding frame 4 moves up and down continuously to prevent it from getting blocked. When the transmission shaft 207 rotates, it also drives the active bevel gear 307 to rotate. Since the active bevel gear 307 is meshed with the driven bevel gear 308, it drives the stirring shaft 304 to rotate. At the same time, each stirring rod 303 rotates to stir the grain passing through the feeding frame 4, further improving the anti-blocking effect of the feeding frame 4. Finally, no manual cleaning is required.
