Detailed Description
In order to make the technical purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are further described below with reference to the accompanying drawings and specific embodiments.
Example 1:
a fodder divides sieve equipment, as shown in fig. 1-3, including the screening cylinder that the slope set up, the screening cylinder slope 30, the higher one end of screening cylinder is the feed end 1, the lower one end of screening cylinder is discharge end 2, the screening cylinder is connected with the drive arrangement transmission and is realized rotating. The screening roller comprises a shell 3 and 3-5 drum sieves which are coaxially arranged in the shell and sleeved at intervals in sequence, wherein the screen holes of the drum sieves are sequentially reduced from inside to outside along the radius direction, and annular grading regions are respectively formed between every two adjacent drum sieves and between the drum sieves and the shell.
In this embodiment, the screening drum comprises a housing 3, and a first drum screen 4, a second drum screen 5 and a third drum screen 6 are coaxially arranged in the housing from inside to outside in sequence, wherein the screen holes are as large as: the first rotary screen is larger than the second rotary screen and larger than the third rotary screen, a driving wheel 14 is sleeved on the periphery of the shell 3, and the driving wheel 14 is in transmission connection with a driving motor through a transmission belt, so that the rotation of the whole screening roller is realized. The grading material area comprises a first-level material area 7, a second-level material area 8, a third-level material area 9 and a fourth-level material area 10 which are sequentially arranged from inside to outside. Discharge doors are respectively and correspondingly arranged at the discharge ends 2 of the first-level material area, the second-level material area, the third-level material area and the fourth-level material area.
The feed to be sieved (feed particles are not uniform with plate clumps) enters the primary feed zone 7 from the feed end 1, the clumps and the feed with larger particles are left in the primary feed zone 7; the feed with the next largest granules enters a secondary material area 8 through a first drum screen 4; the medium-sized grains of feed enter a third-level material area 9 through a second drum screen 5; finally, the small-particle feed enters a four-stage feed area 10 through a third drum screen 6. And finally, along with the rotation of the drum screen, the feed in the drum can be gradually conveyed to the discharge end 2 because the drum screen inclines by 30 degrees, and the discharge doors of all levels of material areas are opened after the feeding is stopped for a certain time, so that the feed in all levels of material areas can be collected and packaged.
In order to enable the hardening blocks in the primary feeding zone 7 to be broken up, a bulk spreader 11 for breaking up the hardening blocks in the feed is arranged in the first trommel screen 4. The concrete structure is as follows: the inner wall of the first drum screen 4 is uniformly distributed with buffer springs 13, one ends of the buffer springs 13 are connected to the inner wall of the first drum screen 4, and the other ends of the buffer springs 13 are used for installing the bulk material hammers 11. The bulk material hammer 11 is integrally provided with a bulk material claw 12 protruding outward at the periphery thereof. Because the bulk material claw 12 is sent out to scattering all around, can strike, collide and break up the great piece fodder (board caking) that gets into in one-level material district 7, the probability of breaking up of board caking can reach more than 90% basically. Effectively improves the quality of the feed. Meanwhile, due to the design of the buffer spring 13, the bulk hammer 11 with heavier mass can continuously shake to the periphery in a reciprocating and undirectional mode under the action of the buffer spring 13, and the impact force of the bulk hammer is utilized to achieve a better scattering effect.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent substitutions and modifications or partial substitutions made without departing from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
