Description

Natural sand and stone material feeding device

Technical Field

The utility model belongs to the technical field of the building stones processing technique and specifically relates to a natural grit feeding device is related to.

Background

The natural sand and stone material yard is produced by adopting natural raw materials of river channels or river beaches, and the natural raw materials have a lot of uncertainty, such as large mud content, large water content, more ultrapath stones and the like. In the feeding process, the mud-stone mixture is adhered to the hopper due to mud content and high water content, so that the feeding speed is reduced; the falling process of the ultrapath stone breaks a receiving belt or blocks a feed inlet due to large volume and heavy weight.

Disclosure of Invention

The utility model aims to provide a simple structure, easy and simple to handle's natural grit material feeding device.

In order to achieve the above purpose, the utility model can adopt the following technical proposal:

The natural sand material feeding device of the utility model comprises a supporting frame with a frame structure and a conical hopper arranged at the top of the supporting frame, wherein the feed inlet of the conical hopper is positioned above the supporting frame, and the feed outlet of the conical hopper extends to the inner side of the supporting frame; the feed inlet of toper hopper seals through the sieve material grid that the slope set up, and the feed opening of toper hopper links up with the vibration feeding machine feed end that sets up below it, vertical spring has been laid in pairs in the both sides limit department of vibration feeding machine, the upper end of vertical spring with the outer wall of toper hopper links to each other, has a plurality of flat plate vibrators that drive its armplate vibrations along the circumference equipartition on the outer wall of toper hopper.

The conical hopper is of a rectangular pyramid structure, and the four flat plate vibrators are uniformly distributed on each arm plate of the conical hopper.

Reinforcing ribs are arranged on the opposite side edges and the middle part of the screening grid in parallel, and the reinforcing ribs are perpendicular to the grid plate of the screening grid.

The utility model has the advantages of simple structure, simple installation and operation. The oversize stone is screened out by obliquely arranging a screening grid at the feeding port of the conical hopper, so that the oversize stone is prevented from being fed into the conical hopper to damage a receiving belt; the hopper wall of the conical hopper is vibrated by the flat vibrators uniformly distributed on the outer side wall of the conical hopper, so that raw materials adhered to the hopper wall are separated from the hopper wall through vibration, the hopper is prevented from being blocked, the feeding speed is increased, the production cost is reduced, the working efficiency is improved, and the reliable guarantee is provided for efficiently producing qualified finished gravel materials from a natural sand gravel source with a complicated condition.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the construction of the screen grid of fig. 1.

Detailed Description

as shown in fig. 1, the natural sand material feeding device of the present invention comprises a supporting frame 1 with a frame structure, and a tapered hopper 2 with a large top and a small bottom arranged on the top of the supporting frame 1, wherein the feeding port of the tapered hopper 2 is positioned above the supporting frame 1, and the discharging port thereof extends to the inner side of the supporting frame 1; the feed inlet of the conical hopper 2 is sealed by the obliquely arranged screening grid 3, and the screening grid 3 can screen out larger stones (oversize stones) in the fed raw materials, so that the blockage of the feed outlet of the conical hopper 2 is avoided, and the damage to a receiving belt caused by the feeding of the oversize stones into the conical hopper 2 can also be avoided; in order to improve the strength of the screen grid 3, reinforcing ribs 7 (shown in fig. 2) are arranged in parallel on opposite sides and in the middle of the screen grid 3, and the reinforcing ribs 7 are perpendicular to the grid plates of the screen grid 3.

The feed opening of toper hopper 2 links up with the vibration feeding machine 4 feed end that sets up below it, longitudinal spring 5 has been laid in pairs in the both sides limit department of vibration feeding machine 4, the upper end of longitudinal spring 5 links to each other with the outer wall of toper hopper 2, vibration feeding machine 4 is driven by the vibrator that sets up on its diapire, along the tensile direction (vertical promptly) of longitudinal spring 5 vibration from top to bottom, the quick raw materials that will fall by 2 feed openings of toper hopper are delivered to the conveyer belt on, and deliver to next process through the conveyer belt, realize the even feed of subsequent handling.

A plurality of flat plate vibrators 6 for driving the arm plates to vibrate are uniformly distributed on the outer wall of the conical hopper 2 along the circumferential direction, and the conical hopper 2 can be designed into a rectangular pyramid structure because the flat plate vibrators 6 have good vibration effect on the flat plate, and the number of the flat plate vibrators 6 is four, and the four flat plate vibrators are uniformly distributed on each arm plate of the conical hopper 2; in addition, because the material sieving grid 3 is obliquely arranged, raw materials can automatically fall onto the side wall of the conical hopper 2 connected with the oblique lower end of the material sieving grid 3 during feeding, and therefore, the flat plate vibrator 6 on the side wall of the conical hopper 2 connected with the oblique upper end of the material sieving grid 3 can be omitted for saving cost.

The utility model discloses an operation process as follows:

On shaking natural sand gravel material source to sieve material grid 3 through the loader, sieve material grid 3 can be with great piece stone (promptly super footpath stone) screen out in the raw materials, avoids super footpath stone to block up toper hopper feed opening, avoids super footpath stone whereabouts to pound bad vibration feeder 4 simultaneously. When the raw materials contain more muddy water, in order to avoid unsmooth feeding caused by the adhesion of the raw materials on the hopper wall of the conical hopper 2, the flat vibrator 6 arranged on the outer wall of the hopper can be opened to vibrate the hopper wall, so that the raw materials adhered on the hopper wall are separated from the hopper wall through vibration, and the feeding speed is increased. The switch of the vibration feeding machine 4 is turned on before feeding, and the vibration feeding machine 4 is hung below the conical hopper 2 through the longitudinal springs 5 on two sides, so that the vibration feeding machine 4 shakes up and down under the rotation of the motor, raw materials falling onto the vibration feeding machine 4 through the conical hopper 2 are uniformly and quickly conveyed to the conveying belt, and the raw materials are conveyed to a washing screening machine of the next process for screening and washing through the conveying belt.
