Description

A kind of pulverizer of hammering the sieve adjustable gaps into shape

Technical field

The utility model relates to the disintegrating apparatus in a kind of grain feed mechanical field, particularly a kind of pulverizer.

Background technology

Existing pulverizer, comprise the main shaft that is horizontally set on the two stands, be fixed with the pulverizer body between the two stands, be arranged at intervals with some hammer frame plates on the main shaft perpendicular to main shaft, hammer frame plate is provided with pin shaft hole, the bearing pin of hammer leaf through passing pin shaft hole is installed on the hammer frame plate, some hammer frame plates form the hammer frame plate assembly, the hammer leaf periphery is provided with the sieve plate that fixes with the pulverizer body, leave the gap between sieve plate and the hammer leaf, charging aperture is left on sieve plate top, and sieve plate is fixed in pulverizer body inboard by hold-down mechanism.During work, main shaft rotates, drive the hammer leaf high-speed motion, to hit broken from the material that charging aperture comes, the effect of sieve plate has been two, one is for to sieve the material of particle diameter less than hole on the sieve plate, it is two for stopping and reflect the material of big particle diameter, make it enter the scope that impacts of hammer leaf, carry out once more broken, require to pulverize different materials in theory and need different hammer sieve gaps (hammer leaf is to the distance between the sieve plate), slightly eccentric setting the between the hammer sieve of the prior art, therefore, hammer sieve gap is not to equate everywhere, because sieve plate top is charging aperture, so the problem in sieve gap can not occur hammering into shape on top, the hammer sieve gap here mainly refers to the gap of hammer leaf and sieve plate bottom, existing pulverizer has only by changing the position of hammer leaf on hammer frame plate in the time of need changing hammer sieve gap and could realize, the pin shaft hole of a plurality of different centre-to-centre spacing promptly is set on hammer frame plate, by realizing the gap adjustment of hammer sieve in the pin shaft hole that hammer leaf is installed in different centre-to-centre spacing, yet, the pin shaft hole of different centre-to-centre spacing has only limited quantity on the hammer frame plate, and waste time and energy when changing hammer leaf place pin shaft hole, and different raw material or when using the sieve plate of different sieve apertures to pulverize, hammer sieve gap is very big to the influence of crush efficiency, thus extremely inconvenient and can't accomplish any adjustment in gap by the pin shaft hole adjustment hammer sieve gap of different centre-to-centre spacing, influenced crush efficiency and operating time.

The utility model content

The purpose of this utility model provides a kind of pulverizer of hammering the sieve adjustable gaps into shape, can be at any time and adjust hammer sieve gap arbitrarily, and make pulverizer pulverize different material or can keep best crush efficiency when using the sieve plate in different apertures.

For achieving the above object, a kind of pulverizer of hammering the sieve adjustable gaps into shape described in the utility model, comprise the main shaft that is horizontally set on the two stands, be fixed with the pulverizer body between the two stands, be arranged at intervals with some hammer frame plates on the main shaft perpendicular to main shaft, some hammer frame plates form the hammer frame plate assembly, each hammer frame plate is provided with pin shaft hole, the bearing pin of hammer leaf through passing pin shaft hole is installed on the hammer frame plate, the hammer leaf periphery is provided with sieve plate, leave the gap between sieve plate and the hammer leaf, charging aperture is left on sieve plate top, the both sides of hammer frame plate assembly are respectively equipped with the sieve plate gripper shoe that is nested with on main shaft, and sieve plate is fixed on the sieve plate gripper shoe through the sieve plate hold-down mechanism, are respectively equipped with the guiding mechanism that can vertically regulate relative position between two sieve plate gripper shoes and the pulverizer body.

What above-mentioned guiding mechanism can comprise on sieve plate gripper shoe and the pulverizer body that level separately stretches out two is connected and fixed part, two are connected and fixed and uprightly are provided with connecting screw rod between the part, connecting screw rod root and two is connected and fixed one of part and fixes, the connecting screw rod end is passed another and is connected and fixed part, and described another is connected and fixed part and is respectively equipped with the adjusting nut that is meshed with connecting screw rod in both sides up and down.

During the utility model work, can regulate the sieve plate gripper shoe up or down by guiding mechanism, the sieve plate that is fixed on the sieve plate gripper shoe is moved up and down, and hammer leaf radially with the support relative fixed, therefore, can sieve the gap by governor weight by guiding mechanism, during adjusting, as long as unclamp the corresponding adjusting nut on the connecting screw rod, to be connected and fixed on the part, the adjusting nut of downside is twisted up or down, and then hammer sieve gap reduces or increases, compared with prior art, the utility model is because can be at any time and adjust hammer sieve gap arbitrarily, makes pulverizer pulverize different material or can keep best crush efficiency when using the sieve plate in different apertures.
