The features and properties of the present invention will be described in further detail with reference to the following examples.

Referring to fig. 1-5, a feeder comprises a vibration device 11, a feeding channel 12 and a conveyor belt 13; the vibration device 11 is a vibration shaft 111 arranged below the feeding channel 12, the vibration shaft 111 is driven by a motor through a belt to rotate, the vibration device 11 adopts mechanical vibration in the prior art, the vibration device has the specific structure that an eccentric weight block 112 is arranged on the vibration shaft 111, and the gravity center shifts when the vibration shaft 111 rotates, so that the feeding channel 12 is driven to vibrate, and the functions of screening and transmission are achieved; the conveyor belt 13 is arranged below the feeding channel 12 and used for collecting the screened small stones, which is equivalent to automatic collection, so that the workload of workers is greatly reduced; the screening device 14 is composed of grate bars 141, and the screening device 14 is arranged in a form that a plurality of grate bars 141 are spliced; when the single grate bar 141 is damaged, the single grate bar can be independently replaced, so that the maintenance cost and the maintenance time of the screening device 14 are reduced.

The grate bars 141 are T-shaped when viewed from the front, and are trapezoidal when viewed from the top, and the upper bottoms of the trapezoids point to the discharge hole; the T-shaped arrangement is convenient for screening; the batcher is the slope when using, makes things convenient for the transmission of raw materials, sets up grid 141 into the trapezoidal structure of seeing from the top again, and it further guarantees the general and further screening of raw materials transmission, because probably appear some not big stones of self in the vibration in the front but because the situation that the edges and corners blocked and can't sieve, and trapezoidal setting can be along with the continuous advance of raw materials, sieve out the preceding little stone that is for sieving out.

A fixing block 142 is arranged below the grate bar 141, and a bolt hole 143 is arranged on the fixing block 142; the grate bars 141 and the feeding channel 12 are connected through bolts through bolt holes 143, and the grate bars 141 are fixed through bolts, so that the grate bars 141 are convenient to replace, and the maintenance cost and the maintenance time of the screening device 14 are reduced.

The feeding channel 12 is provided with a spring as a damping device 15, so that the stability of the whole mechanism of the feeder under the vibration driven by the vibration device 11 is ensured, and the good damping can further improve the screening and transmission efficiency of the feeder.

The screening device 14 is divided into a first screening layer 144 and a second screening layer 145, the second screening layer 145 is arranged below the first screening layer 144, the tail end of the first screening layer 144 extends to the front end position of the second screening layer 145, and the double screening layers can be arranged more fully for screening, and the principle is as follows: the gaps between the grate bars 141 in the second screening layer 145 are enlarged, so that small stones which are not screened in the first screening layer 144 originally can be screened in the second screening layer, and small stones in the raw materials are screened as much as possible, so that the load of the crusher is reduced, and the service life of the crusher is prolonged.

The two sides of the feeding channel 12 are provided with the side plates 122, the inner sides of the side plates 122 are provided with the lining plates 123, the lining plates 123 are connected with the side plates 122 through bolts, the rigidity of the feeding machine is greatly enhanced due to the arrangement of the lining plates 123, and the stability of the structure of the feeding machine is ensured; a feed inlet baffle 121 is arranged at the feed end of the feed channel 12, and the feed inlet baffle 121 is arranged to prevent raw materials from directly falling from the feed inlet when the raw materials are fed from the feed inlet, so that the raw materials are fully screened; a bottom cushion plate 124 is arranged on the feeding channel 12, the bottom cushion plate 124 is flush with the first screening layer 144 in height, and the tail end of the bottom cushion plate 124 is tightly connected with the front end of the first screening layer 144; the bottom backing plate 124 is connected with the feeding channel 12 through bolts, and the bottom backing plate 124 is arranged to ensure that a certain buffer is generated when raw materials fall from the feeding hole, so that the safety performance of the feeding machine is improved.

When the feeding device is used, the motor is turned on to rotate the motor, so that the vibration shaft 111 is driven to rotate, and the gravity center of the vibration shaft 111 is continuously changed by the eccentric balancing weight 112 on the vibration shaft 111 in the rotating process, so that the feeding channel 12 is driven to vibrate, and the functions of screening and transmission are achieved; then, the raw materials are fed from the feeding end of the feeding channel 12, and the feeding hole baffle 121 is arranged to prevent the raw materials from directly falling from the feeding hole when the raw materials are fed from the feeding hole; the raw material continuously moves forwards in the continuous vibration process, smaller stones fall onto the conveyor belt 13 through gaps between the grate bars 141 of the first screening layer 144 and the second screening layer 145 to be collected, and the screened raw material falls into the crusher from the tail end of the feeding channel 12 to be subjected to post-processing steps.

The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but it should not be understood as the limitation of the protection scope of the present application, it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the technical solution idea of the present application, and these all fall into the protection scope of the present application.
