Description

A kind of grinding screen sieve

Technical field

The utility model belongs to feed processing equipment technology field, and in particular to a kind of grinding screen sieve.

Background technique

During pig production, Grinding Particle Size of Feeds has great influence to the digestion and absorption of pig.When piglet feeds scalping When the feed of crushing, will result in have loose bowels, indigestion the problems such as.And when the hog feeding thinner feed of crushing, it can also face Gastric ulcer and other dyspeptic symptoms give the feed of suitable particle size thus according to the growth phase of pig, have weight The production meaning wanted.In a line production process, pig farm mainly uses a pulverizer, during powder, to sieve into Row replacement, to obtain suitable feed granularity.The feed of different-grain diameter is obtained by replacement sieve, gives operation band in production Come it is inconvenient, or even due to different sieve models mismatch, it is in irregular shape and inconvenient to use the problems such as, appearance do not change sieve The phenomenon that piece, unified feed granularity is fed.The problems in sieve use process in production is analyzed, discovery mainly by Following reason causes: (1) in production scene, there is deformation in sieve, not match with existing slot position, inconvenience replacement.(2) one is produced The large labor intensity of line, arrangement of time is tighter, and replacement sieve is more time-consuming, reduces working efficiency, it is therefore desirable to easily facilitate The multi-purpose type sieve of operation.

The first sieve between described two conducting bars is equipped with several first sieve pores.

Second sieve is equipped with aperture the second sieve pore identical with the first sieve pore and aperture less than the first sieve pore Third sieve pore.

Second sieve pore is consistent with the distributing position of the first sieve pore, and the third sieve pore is set to the second sieve pore front-rear direction Gap location.

The waist-shaped hole for extending along the longitudinal direction and matching, the waist type are equipped in first sieve and the second sieve Fastening bolt is equipped in hole.

Further, mounting plate is respectively provided at left and right sides of first sieve, mounting plate is equipped with threaded hole.

Further, first sieve pore is equipped with several rows along the longitudinal direction, and the spacing that often ranked first between sieve pore is greater than Equal to the aperture of the first sieve pore, second sieve pore is consistent with the distributing position of the first sieve pore.

Further, the third sieve pore ranked second the middle position between sieve pore set on two.

Further, the aperture of first sieve pore and the second sieve pore is 3.5mm, and the aperture of the third sieve pore is 1.5mm。

The utility model has the beneficial effects that

1) the utility model realizes screen-aperture by being equipped with the first sieve and the second sieve, and by two sieve slidings Adjustment.The length and width of second sieve is respectively less than the length and width of the first sieve, and the setting of the second sieve will not influence original The installation of first sieve, to ensure that the compatibility of sieve.

2) first sieve and the second sieve are installed by waist-shaped hole, have both provided the mobile space of the second sieve, together When two sieves are fixed together by fastening bolt.

Specific embodiment

A kind of grinding screen sieve, as shown in Figs. 1-5, including the first sieve 1, and it is close to the second of 1 bottom surface of the first sieve Sieve 2.The length and width of second sieve 2 is respectively less than the length and width of the first sieve 1, and the setting of the second sieve 2 will not influence original The first sieve 1 installation, to ensure that the compatibility of sieve and pulverizer.

First sieve, the 1 bottom arranged on left and right sides is respectively equipped with the conducting bar 13 extended along the longitudinal direction, second sieve 2 are equipped with sliding slot 24 with 13 position corresponding section of conducting bar, and the conducting bar 13 is slidably connected with sliding slot 24.Second sieve 2 can be along The extending direction of conducting bar 13 slides.

The first sieve 1 between described two conducting bars 13 is equipped with several first sieve pores 12.In the present embodiment, described One sieve pore 12 is equipped with several rows along the longitudinal direction, often ranked first the hole that the spacing between sieve pore 12 is more than or equal to the first sieve pore 12 Diameter.

Second sieve 2 is equipped with aperture second sieve pore 23 identical with the first sieve pore 12 and aperture less than first The third sieve pore 22 of sieve pore 12.In the present embodiment, second sieve pore 23 is consistent with the distributing position of the first sieve pore 12, and described Three sieve pores 22 ranked second the middle position between sieve pore 23 set on two.

In the present embodiment, the aperture of first sieve pore 12 and the second sieve pore 23 is 3.5mm, the hole of the third sieve pore 22 Diameter is 1.5mm.

It is set in first sieve 1 there are four the first waist-shaped hole 14 for extending along the longitudinal direction, is set in second sieve 2 There are four the second waist-shaped hole 21 to match with the first waist-shaped hole 14, it is equipped in first waist-shaped hole 14 and the second waist-shaped hole 21 Fastening bolt.On the one hand first waist-shaped hole 14 and being used cooperatively for the second waist-shaped hole 21 can fasten the first sieve 1 and the second sieve On the other hand piece 2 meets the sliding of the second sieve 2.
