Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1, the raw grain screening apparatus for fodder according to the preferred embodiment of the present invention includes a cambered brush body 3 and a screen box 7 disposed on a bracket 1.

Wherein, the both sides of cambered surface brush body 3 utilize the spring to set up on support 1 as elastic buffer 2, and its lower surface is the cambered surface to it has one deck steel brush hair as stereoplasm brush hair 4 to shape on the cambered surface.

The screen box 7 is a movable structure box body, two sides of the screen box are provided with screen frames 11 and are connected with a vibration motor through the screen frames 11, a plurality of groups of screen mesh mounting frames 8 are arranged at the inner side of the screen box 7 corresponding to the screen frame 11, and four groups of screen meshes are arranged through the screen mesh mounting frames 8, namely a first screen 5, a second screen 6, a third screen 10 and a fourth screen 12, wherein the first screen 5 is a concave cambered screen, the corresponding radian of the brush body is larger than that of the cambered surface of the brush body 3, so that a variable gap is formed between the hard brush bristles 4 at the lower part of the brush body 3 and the upper surface of the first screen 5, the gap distance of the variable gap is gradually increased from the middle to the two sides, and the distance between the hard brush hair 4 and the first screen 5 can be adjusted by adjusting the mounting position up and down on the elastic buffer 2, so as to ensure that the variable clearance falls into the range of 0.5-3 times of grain diameter of grains to be screened.

And second screen cloth 6, plane combination screen cloth is constituteed to third screen cloth 10 and fourth screen cloth 12, set up in first screen cloth 5 lower part, and first screen cloth 5, second screen cloth 6, the sieve mesh clearance of third screen cloth 10 and fourth screen cloth 12 subtracts progressively, in order to guarantee the order screening out the cereal granule of different particle diameters, second screen cloth 6, third screen cloth 10 and fourth screen cloth 12 are the plane screen cloth, and install through corresponding screen cloth both sides screen cloth mounting bracket 8 respectively in both sides, be provided with height-adjustable's support in the screen cloth mounting bracket 8, and the inclination of height adjustment screen cloth through adjusting screen cloth mounting bracket 8, so that the contained angle control between the screen cloth that corresponds and the horizontal plane is in 20~30 within ranges. In addition, a separation partition plate 13 is further disposed at the bottom of each planar screen corresponding to the screen mounting frame 8, so as to form a blanking channel 9 between adjacent separation partition plates 13 and between the separation partition plate 13 and the wall of the screen box 7, while in this embodiment, the blanking channels 9 corresponding to the oversize products of the second screen 6, the third screen 10 and the fourth screen 12 are respectively connected to a first blanking channel 14, a second blanking channel 17 and a third blanking channel 15, and the undersize product of the fourth screen 12 corresponds to a fourth blanking channel 16, so that the grain particles of the raw grain screening device to be fed are screened into four groups of particles with different particle sizes by the screening device, and are connected to the storage tank seat collecting container for collection through the corresponding blanking channels.

This embodiment is when using, the cereal raw materials that smash in the last process are added from first screen cloth 5's both sides, start the vibrating motor that 11 outer links of bank of screens simultaneously, vibrating motor makes first screen cloth 5 and plane combination screen cloth homoenergetic realize the effect of shale shaker through driving 11 vibrations of bank of screens, with improve equipment utilization ratio, and the cereal that gets into clearance between first screen cloth 5 and the stereoplasm brush hair 4 can be through the extrusion of stereoplasm brush hair 4, and carry out the secondary crushing with the caking granule of big particle diameter, and be crowded screen cloth clearance in crushing process, stereoplasm brush hair 4 can also play the effect of lasting levigated cereal granule and mediation screen cloth simultaneously, and finally most oversize passes through the screen cloth. In addition, the cambered surface brush body 3 is connected with the support 7 through the elastic buffer part, the flexible impact between the first screen cloth 5 and the hard brush bristles can be guaranteed when the screen box 7 is subjected to vibration screening, the wear rate is reduced, in addition, the service life of the first screen cloth 5 can be prolonged by adopting wedge-shaped screen cloth gaps with narrow upper parts and wide lower parts as shown in fig. 2 for the first screen cloth 5, and the steel brush bristles adopted by the first screen cloth 5 have better wear resistance on one hand, the positions of the cambered surface brush body 3 on the elastic buffer part 2 can be adjusted after the surface layer is worn, the brush bristle surfaces of the hard brush bristles 4 can be moved downwards for continuous use, and the steel scraps and the brush bristles which are worn and dropped by the hard brush bristles 4 in the use process of subsequent necessary magnetic separation can be screened out together, so that the process cannot be additionally increased, and the device is very convenient.

The grain particles of the first screen 5 directly enter the plane combined screen, and four grain raw material particles with different particle sizes from large to small are sequentially screened out through the sequential screening of the vibrating screen so as to meet the processing requirements of different feeds.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
