Abstract

The utility model designs a hammer crusher combined arc casting sieve plate. The structure of a sieve plate is that 2-6 high strength wear resisting alloy steels are cast into an arc sieve plate (1). A plurality of sieve-meshes (2) are provided on the sieve plate and the radian of each sieve block is 30-90 degrees. A 180 degree semi-arc combined by a plurality of arc casting sieve plates is embedded in an inside chamber of a crusher. The service life of the utility model is 3-5 times that of the traditional welding grizzly and steel plate drilled hole sieve plate, the wear resistance is strengthened, the times of dismounting are reduced and the labor productivity is improved.

Description

The combined arc-shaped casting screen plate of hammer mill

(1) technical field:

The combined arc-shaped casting screen plate of hammer mill that the utility model is designed be to be used for broken building stones and ore in the construction material machinery, and this arc casting screen plate belongs to the easily worn part in the disintegrating machine.

(2) background technology:

The bar grizzl(e)y that the hammer mill tradition is used is to adopt the electric welding soldering group to synthesize bar grizzl(e)y with A3 steel or No. 45 steel again through forging into square bar, reason owing to material and technology, its wearability and fastness are all relatively poor, and hole sizer also is by boring with the A3 steel plate, roll bending forms, the not only time-consuming material that takes, processing cost height and wearability hardness is all very low, at above-mentioned defective, adopt high strength, the bar grizzl(e)y of the hammer mill of highly wear-resisting alloy steel casting and hole sizer sieve plate, not only durable in use, and reduce the dismounting number of times, can improve labour productive forces, reduce user's labour intensity.

Improve 3-5 doubly service life than traditional sieve plate.

(3) summary of the invention:

The combined arc-shaped casting screen plate of hammer mill that the utility model is designed, select potassium steel, the moulding of high-strength wear-resistant alloy steel one-step casting for use, the structure of sieve plate is formed with 2-6 piece arc cast sheet, the radian of every sieve plate is that 30 degree are to 90 degree, the thickness of arc casting screen plate is 5mm-40mm, be provided with a plurality of strips hole in the casting arc screening plate bar grizzl(e)y, the two ends of bar hole are curved, and the bar pitch of holes is between 4mm to 25mm.Be provided with several holes, garden in the sieve plate of garden.The aperture is between 5mm to 60mm.

Above-mentioned polylith arc piece is combined into the bar hole sizer, garden hole sizer plate embeds thorax in the hammer mill body.

(4) description of drawings:

Fig. 1 is the structural representation of the combined arc-shaped casting screen plate of hammer mill, 1-arc screening plate, 2-sieve aperture.

Fig. 2 is the side structure schematic diagram of the combined arc-shaped casting screen plate of hammer mill, 1-sieve plate, 2-sieve aperture.

Fig. 3 is the installment state schematic diagram of the combined arc-shaped casting screen plate of hammer mill on body, thorax in the 1-sieve plate, 3-body.

(5) specific embodiment:

The combined arc-shaped casting screen plate of hammer mill that the utility model is designed, the structure of sieve plate is by 2 to 6 high strength, wear-resisting alloy steel is cast as arc screening plate (1), have several sieve apertures (2) on the sieve plate, the radian of every sieve plate is that 30 degree are to 90 degree, polylith arc casting screen plate is combined into one and half garden arcs of 180 degree, the thickness of sieve plate is 5-40mm, be provided with a plurality of strip sieve apertures (2) in the arc strip sieve plate, the two ends system of bar hole is half garden arc, between the bar pitch of holes 4-25mm, be provided with several holes, garden in the hole sizer plate of garden, the aperture is between 5-60mm, above-mentioned polylith arc casting screen plate piece is combined into cylindrical void sieve plate or garden hole sizer plate polylith and is combined into half garden arc among Fig. 3, embeds thorax in the hammer mill body.

Claims

1, the designed combined arc-shaped casting screen plate of hammer mill of the utility model, the structure that it is characterized in that sieve plate is cast as arc screening plate (1) by 2 to 6 blocks of high-strength wear-resistant alloy steel, have several sieve apertures (2) on the sieve plate, the radian of every sieve plate be 30 the degree to 90 the degree, by polylith arc casting screen plate be combined into 180 the degree half garden arc screening plates.Embed thorax in the disintegrating machine body.

2, by the combined arc-shaped casting screen plate of the described hammer mill of claim 1, the thickness that it is characterized in that sieve plate is that the two ends that are provided with a plurality of strip sieve apertures and garden sieve aperture (2) bar hole in the 5-40mm bar sieve plate are half garden arc, pitch of holes is between 4-25mm, and garden hole sizer panel aperture is between 5-60mm.
