[0002] Feed is the general term for the food of all animals raised. More narrowly, feed generally mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, grease, meat and bone meal, grains, and feed additives. With the continuous development of modern livestock and poultry farming, the utilization rate of feed in these aspects is also getting higher and higher.

[0003] The existing Chinese utility model patent with the patent number CN202322402775.9 discloses "An anti-blocking feed salt sub-packaging and discharging device". Through the setting of grinding rollers and sieve plates, the agglomerated feed is ground and dispersed into finer feed powder, preventing the agglomerated feed from blocking the discharge port. The rotation of the rotating rod drives the dredging ball at the same time, and the dredging ball rotates continuously at the discharge port to prevent the feed from adhering to the side wall of the discharge port, further preventing the blockage of the discharge port. The blockage warning device enables the staff to discover in time when the discharging device is blocked, and spontaneously drives the air cylinder and the baffle to close the feed inlet to stop feeding, and the alarm timely reminds the staff to dredge.

[0004] Although the above-mentioned utility model has certain advantages in anti-blocking and alarming, there are still certain defects:

[0034] The material screening component 202 includes:

[0035] A first arc-shaped material screening plate 208, and the right end of the first arc-shaped material screening plate 208 is fixedly connected to the left side surface of the fixed long rod 209;

[0037] The working principle of a feed automatic screening box for preventing blockage implemented based on the above is:

[0038] Pour the feed from the feed hopper 102 into the inside of the observation cover plate 103, and then drive the crushing roller 204 to rotate on the top surface of the second arc-shaped sieve plate 213 through the output shaft of the first driving motor 206 in cooperation with the transmission belt, so as to drive the sweeping roller 203 to rotate on the top surface of the first arc-shaped sieve plate 208 through the synchronous transmission belt 207, and then carry out the sieving work through the cooperation of the sweeping roller 203 with the first arc-shaped sieve plate 208 and the first sieve holes 210. Part of the feed with a larger volume is pushed into the inside of the second arc-shaped sieve plate 21 by the rotation of several short rods on the surface of the sweeping roller 203, and is ground and dispersed by the crushing roller 204, and the feed that has been ground and dispersed is screened and dropped into the storage bin 303 through the second sieve holes 214;

[0039] During this process, the output shaft of the second driving motor 212 drives the rolling shaft 211 to rotate on the top surface of the fixed long rod 209, so as to prevent the material from piling up on the top surface of the fixed long rod 209 when transitioning from the first arc-shaped sieve plate 208 to the second sieve holes 214;

[0041] The utility model provides an anti-blocking automatic feed sieving box through improvement. The sweeping roller 203 cooperates with the sieving assembly 202 to push part of the feed with a larger volume towards the crushing roller 204, and the crushing roller 204 grinds and disperses the feed with a larger volume to avoid blockage caused by larger feed. At the same time, the two groups of sieve holes of the sieving assembly 202 carry out sieving at the same time, which improves the sieving efficiency and further avoids blockage of the sieving assembly 202. The four third driving motors 301 cooperate with the connecting rods 302 to swing the storage bin 303 reciprocally, so as to level the piled feed after sieving, and the piled height of part of the feed exceeds the bearing range.
