and the dust collecting device and the winch cage at the lower part are independent, so that dust is easy to accumulate, and manual timing cleaning is needed.
Disclosure of Invention
In order to solve the problems, the utility model provides a grass screening plate of a pulverizer.
The utility model adopts the technical scheme that: a grass screening plate of a pulverizer,
comprises a grass screening plate and a soil accumulation plate arranged below the grass screening plate;
one end of the soil accumulation plate, which is close to feeding, is movably connected with the grass screening plate through a first connecting plate;
a second connecting plate is arranged at one end of the soil accumulating plate, which is far away from the feeding;
at least two fixed shaft heads are respectively arranged on two longitudinal sides of the grass screening plate;
the bottom of the soil accumulation plate is provided with two soil receiving plates, the two soil receiving plates are arranged at two sides of the material conveying direction, and a dust discharge port is formed between the two soil receiving plates; the two soil receiving plates incline downwards towards the dust exhaust port.
Further, the grass screening plate comprises a rectangular frame body and a screen mesh arranged on the upper surface of the frame body; the frame body is provided with longitudinal reinforcing ribs.
Further, the mesh number is 10-50 mesh.
Further, a first mounting hole is formed in the top of the first connecting plate, and a second mounting hole is formed in the top of the second connecting plate.
Compared with the prior art, the utility model has the beneficial effects that: the grass screening plate of the pulverizer is connected with the power of the pulverizer, the fixed shaft head is arranged in the inclined strip-shaped groove on the side wall of the discharge bin, and the grass screening plate is driven to move obliquely upwards through the transmission block, so that crushed straws do periodic parabolic motion towards the direction of the discharge hole, contact with the screen cloth when falling down, have small gravity and inertia effects, dust is separated from the straws, falls onto the soil accumulation plate below from the screen cloth, and the soil accumulation plate swings left and right, so that the dust can be discharged from the dust discharge hole.
Drawings
FIG. 1 is a schematic view of a grass screen plate of a pulverizer provided by the utility model;
FIG. 2 is a schematic view of the structure of a grass screen;
FIG. 3 is a schematic view of a soil accumulation plate;
wherein: grass screening plate 1, soil accumulating plate 2, first connecting plate 3, second connecting plate 4, fixed spindle nose 5, soil receiving plate 6, dust exhaust port 7, framework 8, screen cloth 9, strengthening rib 10, first mounting hole 11, second mounting hole 12.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 3, the present embodiment provides a grass screen plate of a pulverizer, comprising a grass screen plate 1 and a soil accumulation plate 2 disposed below the grass screen plate 1; the grass screening plate 1 comprises a rectangular frame body 8 and a screen 9 fixed on the upper surface of the frame body 8, the frame body 8 is made of square steel, and the frame body 8 is provided with longitudinal reinforcing ribs 10, so that the screen 9 is prevented from deforming or falling off from the bottom of the frame body 8 after long-time use;
one end of the soil accumulating plate 2, which is close to feeding, is movably connected with the grass sieving plate 1 through two first connecting plates 3; the end of the soil accumulating plate 2, which is far away from the feeding, is provided with two second connecting plates 4 for hanging the soil accumulating plate 2 in the discharging bin;
the first connecting plate 3 and the second connecting plate 4 are integrally L-shaped, and the transverse edges are fixed with the bottom surface of the frame body 8;
two fixed shaft heads 5 are respectively arranged on two longitudinal sides of the grass screening plate 1, and the two fixed shaft heads 5 are spaced at a certain distance, so that the grass screening plate 1 can move more stably;
the bottom of the soil accumulation plate 2 is provided with two soil receiving plates 6, the two soil receiving plates 6 are arranged at two sides of the material conveying direction of the soil accumulation plate 2, and a dust discharge port 7 is formed between the two soil receiving plates 6; the two soil receiving plates 6 are inclined downwards towards the dust discharge opening 7, so that dust can move downwards along the soil receiving plates 6 and be discharged from the dust discharge opening 7;
the mesh number of the screen mesh 9 is determined according to the pulverizing effect of the pulverizer, and the screen mesh 9 aims to prevent the straw from passing through the screen mesh 9 as long as the effect can be achieved, and the mesh shape is not particularly limited, but in the present embodiment, the mesh of the screen mesh 9 is rectangular, the mesh is enlarged in the drawing, and the purpose is to clearly show the screen mesh structure, and the mesh number of the screen mesh in the present embodiment is 20 mesh.
