Abstract
The utility model provides a rod formula sieve that rod formula sieve (b), (b) relate to vibrating feeder accessory, especially a vibrating feeder who is applicable to hierarchical material. The utility model discloses a rod formula sieve, this sieve of its characterized in that includes bottom plate and grating, and the grating amounts to strip, parallel arrangement, the bottom plate is two parallel arrangement's steel sheet, fixes respectively in the bottom at grating both ends for every, and it is perpendicular with the grating, material flow direction parallel arrangement is followed to the grating. The utility model discloses a rod formula sieve, design science, it is rational in infrastructure, convenient to use, the cast steel grating is formed by the alloy steel casting, has fine wearability and anti shock -resistant ability, improved the life of sieve, has reduced the number of times that the user changed the sieve, the while grating is trapezoidally, reduces along the material flow direction for the sieve mesh changes from small to big, and the material is not blockked through the sifter time, reduces the jam probability of sieve mesh, has improved screening efficiency and feed ability.
Description
Technical field
The utility model relates to oscillating feeder accessory, especially a kind of Bar strip type sieve plate being applicable to the oscillating feeder of point stage material.
Background technology
Oscillating feeder is widely used in mine, metallurgical, coal, building materials, chemical industry, the screening feed operation of the industries such as electric power, and sieve plate is workpiece the most basic in oscillating feeder, the large multiplex rail steel welding of traditional sieve plate, or form by bolt and screen frame are directly fixing with many rods, during work, the material being less than sieve aperture becomes screenings by sieve aperture, the material being greater than sieve aperture constantly moves forward on sieve plate face, until the discharging opening of oscillating feeder and enter next process, the quality of sieve plate directly has influence on screening efficiency and the disposal ability of oscillating feeder in the course of the work.
Because sieve plate many employings rail steel of traditional oscillating feeder welds, or many rods are directly fixedly formed by bolt and screen frame.Therefore, the sieve aperture of existing sieve plate is all fixed dimensions, and when sieve aperture is less, material easily causes sieve pore blockade by compass screen surface, must shut down cleaning sieve aperture, and when sieve aperture is larger, feed, screening effect can be caused again poor, greatly reduce operating efficiency time serious.
And existing sieve plate, the flatness of its contact surface is poor, and fixing bolt is more, and in use, bolt easily loosens, and is difficult to fastening after loosening, operation inconvenience, and fault rate is higher.Meanwhile, in feed operation, material is comparatively large to the impulsive force of sieve plate, requires that sieve plate has certain impact resistance and wearability.Existing sieve plate is directly fixed by bolt, and fixing unreliable, impact resistance is more weak, easily bolt looseness occurs after impact, and cause relevant parts and components to damage time serious, fault rate is high, adds user's maintenance, repair rate.
Summary of the invention
To be solved in the utility model is exactly the sieve plate of existing oscillating feeder, its screen size is fixed, and when sieve aperture is less, easily blocks, when sieve aperture is larger, feed, screening effect are poor, and the bolt that adopts is fixed more, fixing unreliable, the problem of impact resistance difference, there is provided a kind of and reduce sieve pore blockade, bolt is fixing reliable, and Maintenance and Repair are Bar strip type sieve plate easily.
Bar strip type sieve plate of the present utility model, it is characterized in that this sieve plate comprises base plate and grating, grating is several, be arranged in parallel; Base plate is two blocks of steel plates be arranged in parallel, and every block is separately fixed at the bottom at grating two ends, and vertical with grating; Grating be arranged in parallel along Flow of Goods and Materials direction.
Its width of described grating reduces along Flow of Goods and Materials direction, and the sieve aperture gap between adjacent two gratings increases along Flow of Goods and Materials direction, guarantees that material is not by being stopped during compass screen surface, increases screening percentage and the mobility of material, increases work efficiency.
Described grating is fixedly connected with base plate by welding manner.
Described base plate is provided with installing hole, when needed, can be fixed by bolt or welding manner.
The grating of steel is made up of steel alloy, and tool has good wearability and resists shock-resistant ability, improves the service life of sieve plate, decreases the number of times that user changes sieve plate; Grating is trapezoidal simultaneously, reduces, sieve aperture is changed from small to big along Flow of Goods and Materials direction, and material, by not stopped during compass screen surface, reducing the blocking probability of sieve aperture, improve screening efficiency and feed ability.
Bar strip type sieve plate of the present utility model, design science, rational in infrastructure, easy to use, cast steel grating is cast by steel alloy and is formed, and tool has good wearability and resists shock-resistant ability, improves the service life of sieve plate, decreases the number of times that user changes sieve plate; Grating is trapezoidal simultaneously, reduces, sieve aperture is changed from small to big along Flow of Goods and Materials direction, and material, by not stopped during compass screen surface, reducing the blocking probability of sieve aperture, improve screening efficiency and feed ability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, base plate 1, grating 2, sieve aperture 3, installing hole 4.
Detailed description of the invention
Embodiment 1: a kind of Bar strip type sieve plate, comprises base plate 1 and grating 2, and grating 2 is several, be arranged in parallel; Base plate 1 is two blocks of steel plates be arranged in parallel, and every block is separately fixed at the bottom at grating 2 two ends, and vertical with grating 2; Grating 2 be arranged in parallel along Flow of Goods and Materials direction.This its width of grating 2 reduces along Flow of Goods and Materials direction, and sieve aperture 3 gap between adjacent two gratings 2 increases along Flow of Goods and Materials direction, guarantees that material is not by being stopped during compass screen surface, increases screening percentage and the mobility of material, increases work efficiency.Grating 2 is fixedly connected with base plate 1 by welding manner.Base plate 1 is also provided with installing hole 4, when needed, can be fixed by bolt or welding manner.
The grating 2 of steel is made up of steel alloy, and tool has good wearability and resists shock-resistant ability, improves the service life of sieve plate, decreases the number of times that user changes sieve plate; Grating 2 is in trapezoidal simultaneously, reduces, sieve aperture 3 is changed from small to big along Flow of Goods and Materials direction, and material, by not stopped during compass screen surface, reducing the blocking probability of sieve aperture 3, improve screening efficiency and feed ability.
