Abstract

The utility model discloses an alfalfa screen sieve which is composed of a machine body, a transmission system, a feed inlet, a conveying auger blade, a main shaft, a beating board, a screen drum, a material blocking rack, a distribution partition board, a discharge door, etc., wherein the front end of the main shaft is provided with the conveying auger blade and the back end thereof is provided with the beating board. The interspace between the beating board and the screen drum can be regulated through a screw bolt, and material discharging speeds and the dwell time of materials in the screen drum can be controlled through regulating the opening degrees of two door panels on the discharge door. Coarse crushing alfalfas enter a conveying auger before entering the screen drum through the feed inlet, and fine leaves enter a leaf discharge port by penetrating through screen holes through the stir of the beating board, but larger stalks slowly move forwards and enter a stalk discharge port through the discharge door along the conic screen drum, in this way, the utility model can achieve the purpose of separating the stalks and leaves of alfalfas.

Description

A kind of clover grass bolter

Affiliated technical field

The utility model relates to a kind of separator, particularly a kind of clover grass separator.

Background technology

In recent years, along with China's pasture growing has already obtained significant progress, herbage produces and the enterprise and the producer of deep processing also constantly are developed, because gross protein value accounts for 70% of complete stool gross protein value in the leaf of clover grass, and protein and energy content are very low in the cane, and the material proportion that cellulose and lignin etc. are difficult to digest is bigger, so the size of leaf proportion has great influence to the quality of feed in the clover grass feed, and on market particularly the selling price of the international market clover grass feed of improving quality and the careless feed of ropy clover very big gap is arranged, in order to improve the quality of clover grass feed, increase the profit of feed processing enterprise to greatest extent, the stem of clover grass is separated with leaf, the content of leaf in the feed is increased, increase Protein content in the feed, thereby improve the quality of feed, farthest increase the food patch added value, improve the benefit of production of fodder producer.

Yet, also be not specifically designed at present the device that the stem with the clover grass separates with leaf.

Summary of the invention

The purpose of this utility model is will provide a kind of can separate the stem and the leaf of the clover grass of process coarse crushing automatically, and effective, the simple in structure a kind of clover grass bolter that separates.

The technical solution of the utility model is: clover grass bolter is made up of body, transmission system, main shaft, conical sieve tube, in body, be provided with conical sieve tube, the center of screen drum is a main shaft, screen drum is provided with charging aperture and discharge door, charging aperture and discharge door lay respectively at the two sides of screen drum, the bottom of charging aperture is a main shaft, is connected with by connecting rod on the main shaft in screen drum to re-pack; Transmission system is connected with main shaft.

Further, connecting rod is provided with oval-shaped slot, re-pack to be connected with bolt in the oval-shaped slot place with connecting rod, by this bolt can regulate re-pack and screen drum between the gap.

Further, the main shaft of the charging aperture of screen drum side bottom is provided with the conveying auger blade, and the clover grass of process coarse crushing is entered by charging aperture and is delivered in the screen drum through the conveying auger blade.

Because the leaf of clover grass is more crisp, after hitting, be easy to be broken into very little particle, then toughness is bigger relatively for the stem of clover grass, after hitting, be not easy to be broken into very little particle, so through after the pulverizing of Roughpulverizer, the leaf of clover grass becomes smaller particles, and stem is not easy fragmentation and is elongated rod shape comparatively speaking.Will the clover grass after coarse crushing enter conveying auger and enter screen drum again by charging aperture, tiny leaf passes sieve aperture through the stirring that re-packs and enters the leaf discharging opening, bigger stem then slowly moves through discharge door to the front along the screen drum of taper and enters the stem discharging opening, thereby reaches the purpose that the stem with the clover grass separates with leaf.

The specific embodiment

Clover grass bolter is made up of body 7, transmission system 9, main shaft 4, conical sieve tube 3, in body 7, be provided with conical sieve tube 3, the center of screen drum 3 is main shafts 4, screen drum 3 is provided with charging aperture 1 and discharge door 16, charging aperture 1 and discharge door 16 lay respectively at the two sides of screen drum 3, the bottom of charging aperture 1 is a main shaft 4, is connected with four by connecting rod 21 on the main shaft 4 in screen drum 3 and

re-packs

5, and 5 the setting angle of re-packing is consistent with the angle of conical sieve tube 3.Connecting rod 21 is provided with oval-shaped slot 22, re-packs 5 to be connected with connecting rod 21 usefulness bolts 14, can regulate re-packing 5 and the gap of 3 of screen drums by this bolt 14.The bottom main shaft 4 of the charging aperture 1 of screen drum 3 sides is provided with conveying auger blade 2.Main shaft 4 is fixed on by two rolling bearing units 6 on the wallboard 8 of body 7, and main shaft 4 one ends are installed transmission system 9, and transmission system 9 is made up of big belt wheel 10, small pulley 11, driving belt 12 and motor 13, and transmission system 9 drives main shaft 4 and rotates.

Send into the charging aperture 1 of clover grass bolter through the clover grass of coarse crushing by preceding road conveying equipment, the conveying auger blade 2 by charging aperture 1 bottom is transported to material in the screen drum 3 of taper endlessly.Because clover blade of grass through coarse crushing is tiny graininess, under conveying auger blade 2 and rotating 5 the effect of re-packing, material tiny leaf through conical sieve tube 3 time just passes sieve aperture, separate from leaf discharging opening 15, because stem toughness is not easy fragmentation more greatly, is the elongated rod shape stem and only wears screen drum 3 and separate from stem discharging opening 17 through discharge doors 16 along conical sieve tube 3.The specification of screen drum 3 sieve apertures can be made the segmentation form, and promptly the screen-aperture of front and back section is different, and the aperture can be according to actual operating position adjustment.Two door-plates 18 that aperture is adjustable are arranged on the discharge door 16, the balanced handle on the door-plate 18 19 is unclamped, door-plate 18 can be along the track move left and right of arc, thereby can reach the purpose of the aperture that adjusts bin gate 16.By adjusting the aperture size of bin gate 16, can control the flowing velocity of material, thus control material final control of time of staying separating effect in screen drum 3.One sub-material dividing plate 20 is installed below the stem discharging opening 17, prevents that leaf and the stem separated from mixing once more.
