In sieve case 1, be located sieve 2 below direction down-dip ground and be equipped with flitch 21 down, flitch 21 welds with the inner wall of sieve case 1 down, and the fertilizer raw materials that are less than the filtration pore are followed sieve 2 and are passed through the entering flitch 21 and along inclined plane roll-off sieve case 1.

The vibration excitation device comprises two vibration motors 5 and bosses, and the two vibration motors 5 are symmetrically connected to the outer walls of the two sides of the screen box 1 through bolts. A base 34 contacted with the ground is arranged below the screen box 1, and a space suitable for the screen box 1 to vibrate is reserved between the screen box 1 and the base 34. The bosses comprise a first boss 31 and a second boss 33, the first boss 31 is provided with a plurality of pairs, preferably three pairs in the embodiment, and each pair of the first bosses 31 is symmetrically welded on the outer wall of the two sides of the screen box 1 close to the base 34. Second boss 33 and base 34 towards the one side fixed connection of sieve case 1 to with the coaxial setting of first boss 31, the joint has spring 32 between first boss 31 and the second boss 33, when vibrating motor 5 drove the vibration of sieve case 1 high frequency, spring 32 is flexible from top to bottom along with the vibration of sieve case 1, makes the fertilizer raw materials that are less than the filtration pore pass through sieve 2 rapidly, reaches the effect of branch sieve.

As shown in fig. 2, the swing mechanism of the present invention is fixed by a fixing frame 3 and is installed in cooperation with the organic fertilizer screening machine. Mount 3 is the door font, divide into horizontal arm and two vertical arms, and the horizontal arm spanes in the top of sieve case 1 feed inlet, and two vertical arms are located the outer wall both sides of sieve case 1 respectively, and vertical arm towards the one end and the base 34 fixed connection on ground. The swing mechanism comprises a telescopic cylinder 4, a swing rod 41 and a rocker 42, the upper end of the rocker 42 is hinged at the center of one surface of the horizontal arm facing the ground, the telescopic cylinder 4 is fixed on the top surface of the horizontal arm through a bolt, one end of the telescopic cylinder 4 facing the hinge point of the rocker 42 and the fixing frame 3 is an output end, the output end stretches out and draws back in the horizontal direction under the driving of the telescopic cylinder 4, the hinge point of the rocker 42 and the fixing frame 3 is spanned by the telescopic stroke of the output end, and the distance from the nearest end of the output end to the hinge point is equal to the distance from the farthest end of. One end of the swing rod 41 is hinged with the output end, the other end of the swing rod 41 is connected with a middle rotating shaft of the rocker 42, the swing rod 41 and the rocker 42 are not on the same horizontal plane, and at the moment, the telescopic cylinder 4, the swing rod 41 and the rocker 42 form a swing mechanism together.
