Technical Field
The utility model belongs to threshing and redrying stalk head, stalk piece rejection equipment field, specific theory relates to a threshing and redrying high screening rate stalk head, stalk piece reject sieve grid of sieve that shakes.
Background
The mixed material comprises stem heads, stem blocks and tobacco stems, the sieve grids of the stem head and stem block removing vibrating sieve are composed of a plurality of sieve bars with certain gaps, and when the mixed material passes through the sieve grids, the sizes of the stem heads and the stem blocks are larger than the intervals of the sieve bars, so that the mixed material can pass through the sieve grids and be uniformly collected; the tobacco stems are smaller than the distance between the sieve bars, and are discharged by a charging chute below the sieve grids after falling from the gaps, and then are collected uniformly.
The sieve bars on the sieve grids for eliminating the stem heads and the stem blocks are cylindrical, and a funnel-shaped arc-shaped groove is formed between the sieve bars. However, the sections of the stems and the stems of the tobacco leaves are flat, and during the screening process, when the stems and the stems pass through the screen grid, the flat stems and the stems easily slide into the arc-shaped grooves between the screen bars under the action of the arc-shaped surfaces of the screen bars. The stem heads and the stem blocks which slide downwards into the grooves are mixed into the tobacco stems in the blanking groove, so that the screening rate is poor.
Therefore, it is necessary to provide a high-sieving-rate eliminating vibrating sieve grid, which can reduce the situation that flat stems and stem blocks slide into a blanking chute from gaps of sieve bars, effectively separate and eliminate the tobacco stems, the stems and the stem blocks, and improve the sieving rate of the eliminating vibrating sieve for the stems and the stem blocks.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that exists among the background art, the utility model provides a rejection of high screening rate shakes and sieves bars makes during stem head, the difficult clearance from the grating of following of stem piece slide into charging chute, improves the screening rate that stem head, stem piece rejected the sieve that shakes.
In order to realize the purpose, the invention is realized by the following technical scheme:
a sieve grid of a threshing and redrying high-screening-rate stem head and stem block removing vibrating sieve comprises rectangular sieve bars 1, supporting legs 2 and two frames 3; the two racks 3 are arranged in parallel, the number of the supporting legs 2 is at least two, each supporting leg 2 comprises a base 4 and supporting bars 5, two ends of the bottom surface of each base 4 are respectively arranged on the two racks 3, each base 4 is perpendicular to the corresponding rack 3, and the top surfaces of the bases 4 are evenly provided with the supporting bars 5 at intervals; the positions of the support bars 5 on the different support legs 2 correspond in sequence, the top of each support bar 5 is connected with a rectangular screen bar 1, and the width of each rectangular screen bar 1 is not smaller than the width of each support bar 5.
Furthermore, the two racks 3 have the same structure, the racks 3 are right-angle racks, and the horizontal arms of the right-angle racks are connected with the bottom surface of the base 4 and are opposite to each other in right angle; or the machine frame 3 is a Z-shaped frame, and a horizontal arm at the upper end of the Z-shaped frame is connected with the bottom surface of the base 4.
Furthermore, one of the two racks 3 is a right-angle rack, the horizontal arm of the right-angle rack is connected with the bottom surface of the base 4, and the right angle of the right-angle rack faces the other rack 3; the other rack 3 is a Z-shaped rack, and a horizontal arm at the upper end of the Z-shaped rack is connected with the bottom surface of the base 4.
The utility model has the advantages that:
the utility model adopts the rectangular screen bars 1 with the structure of cuboid, so that the screen grid working surface for eliminating the vibrating screen is a plane, and a funnel-shaped arc groove can not be formed between the rectangular screen bars 1; the sizes of the stem heads and the stem blocks are larger than the space between the rectangular screen bars 1, so that the stem heads and the stem blocks are not easy to fall down from the gaps between the rectangular screen bars 1; the tobacco stems are smaller than the distance between the rectangular screen bars 1, and after falling from the gaps, the tobacco stems are discharged by a blanking groove below the screen grids and then collected uniformly. The screening rate of the stem heads and the stem blocks is effectively improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below to facilitate understanding of the skilled person.
As can be seen from fig. 1-3, a sieve grid of a threshing and redrying high-sieving-rate stalk and stalk block removing and vibrating sieve comprises a rectangular sieve bar 1, supporting legs 2 and two frames 3; the two racks 3 are arranged in parallel, the number of the supporting legs 2 is two, each supporting leg 2 comprises a base 4 and supporting bars 5, two ends of the bottom surface of each base 4 are respectively arranged on the two racks 3, each base 4 is perpendicular to the corresponding rack 3, and the top surfaces of the bases 4 are evenly provided with the supporting bars 5 at intervals; the positions of a plurality of support bars 5 positioned on different support legs 2 correspond in sequence, the top of each support bar 5 is connected with a rectangular screen bar 1, the two ends of the same rectangular screen bar 1 are respectively connected to the support bars 5 corresponding to the front support leg and the rear support leg 2, and the width of each rectangular screen bar 1 is not less than the width of each support bar 5.
