Abstract

A vibration grain sorting sieve resolves the problems of low efficiency and poor sorting effect of existing vibration sorting sieves, and comprises a frame, a sieve seat, a sieve body, a sieve surface, electric vibration exciters, an elastic element and an angle adjusting device. The electric vibration exciters are mounted on two sides of the sieve body which is mounted on the sieve seat through the elastic element, one end of the sieve seat is hinged onto the frame, the other end of the sieve seat is connected with the frame through the angle adjusting device, and the sieve surface is arranged inside the sieve body. The vibration grain sorting sieve is characterized in that the sieve surface consists of two sieve sheets which are connected together and form an included angle phi, namely the two sieve sheets are not coplanar. The vibration grain sorting sieve has the advantages that the included angle phi is formed between the two sieve sheets, and the inclining angle of the lower sieve sheet is smaller than that of the upper sieve sheet, so that kernels in materials can be prevented from not keeping moving downward but moving upward. Sorting effect is improved, sorting efficiency of the vibration grain sorting sieve is up to 95%, sorting range is wider, and the vibration grain sorting sieve is applicable to sorting of seeds and kernels of various materials.

Description

Crop vibrative final election sieve

Technical field

The utility model belongs to a kind of agricultural product sorting unit, particularly a kind of crop vibrative final election sieve.

Background technology

In the processing of agricultural product, often to carry out sorting removal of impurities or hierarchical processing, to guarantee the quality of product to the material after the shelling.At present, the common equipment that is used for sorting removal of impurities or hierarchical processing in the prior art is a vibration final election sieve, and it mainly is made up of framework, sieve seat, sieve nest, compass screen surface, electric activator, flexible member and angle regulator etc.Electric activator is installed in the both sides of sieve nest; Sieve nest is installed on the sieve seat through flexible member, and an end of sieve seat is hinged on the framework, and the other end is connected with framework through angle regulator; Compass screen surface is arranged in the sieve nest, and the angular adjustment of compass screen surface and sieve nest mainly realizes through angle regulator.In order to improve separating effect, vibration final election sieve adopts many usually and is used in combination, and compound mode or be horizontally disposed with, or vertical the setting all are difficult to the degree that reaches desirable but separating effect is set in any case, and the efficiency of separation is merely about 90%.Its main cause is: compass screen surface is as a whole, and its angle can only be along with the whole adjustment of sieve nest.During sorting, the benevolence in the material moves upward under the effect of vibration, and the seed of not opening shell then moves downward, but always some benevolence can move downward along with the seed of not holding shell, and seed, benevolence sorting are not thorough.Just can only carry out repeatedly final election in order to reach desired separating effect through the mode that increases sieve nest quantity.And this has increased the volume of equipment, has increased the cost of complete equipment and has used energy consumption, has reduced production efficiency, simultaneously, has also increased the difficulty of operation and management.

Summary of the invention

The technical problem that the utility model will solve is, overcomes existing vibration final election screening and selects weak effect, inefficient problem, a kind of good separation effect is provided, the crop vibrative final election sieve that production efficiency is high.

The utility model comprises framework, sieve seat, sieve nest, compass screen surface, electric activator, flexible member and angle regulator, and electric activator is installed in the both sides of sieve nest, and sieve nest is installed on the sieve seat through flexible member; One end of sieve seat is hinged on the framework, and the other end is connected with framework through angle regulator, and compass screen surface is arranged in the sieve nest; Its special character is; Compass screen surface is made up of two sieve sheets, and two sieve sheets link together, and between two sieve sheets an angle Ф is arranged; Promptly two sieve sheets improve separating effect through the angle that changes the sieve sheet not on same plane.

The advantage of the utility model is between two sieve sheets an angle Ф is arranged, and promptly two sieve sheets are not on same plane; Following sieve sheet is littler than the angle that top sieve sheet tilts, and can prevent that the benevolence in the material from continuing to move down, and it is moved upward again; Thereby improved the effect of sorting; Its efficiency of separation has reached 95%, and the scope of sorting is wideer, goes for seed, the benevolence sorting of more kinds of materials.

The specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises framework 3, sieve seat 2, sieve nest 5, compass screen surface, electric activator 4, flexible member 1 and angle regulator 6; Electric activator 4 has two, is installed in the both sides of sieve nest 5 respectively, and sieve nest 5 is vibrated; Sieve nest 5 is installed on the sieve seat 2 through flexible member 1, and flexible member 1 be a helical spring, and flexible member 1 makes that formation elasticity is connected between sieve nest 5 and the sieve seat 2, thereby under the vibration of electric activator 4, material is carried out the sorting processing; One end of described sieve seat 2 is hinged on the framework 3, and the other end is connected with framework 3 through angle regulator 6, and through the adjustment of angle regulator 6 realizations to sieve nest 5 angles of inclination; Compass screen surface is arranged in the sieve nest 5, and described compass screen surface is made up of two sieve sheets, promptly sieves sheet 9 and sieve sheet 10; Sieve sheet 9 is the lip(ped) sieve sheet with sieve sheet 10, also can be flat board with holes, and perhaps the surface has protruding flat board; Can also be the screen cloth of metal wire knitted, confirm that sieve sheet 9 links together with sieve sheet 10 according to the material variety of sorting; Sieve sheet 9 is positioned at the upper end of sieve nest 5, and sieve sheet 10 is positioned at the lower end of sieve nest 5, between sieve sheet 9 and the sieve sheet 10 an angle Ф is arranged; Promptly sieve sheet 9 and sieve sheet 10 not on same plane, the angle that sieve sheet 10 tilts is littler than the angle of sieve sheet 9 inclinations, improves separating effect through the angle that changes between sieve sheet 9 and the sieve sheet 10; The size of angle Ф between sieve sheet 9 and the sieve sheet 10 is not limit; Can adjust according to the kind of sorting material, described sieve sheet 9 also can be same sieve sheet with sieve sheet 10, through bending top and lower part shape is had a certain degree; In the lower end of sieve nest 5 discharging opening 8 is arranged, discharging opening 8 discharges the seed that sorts out, and a discharging opening 7 is arranged in the upper end of sieve nest 5, and discharging opening 7 discharges the benevolence that sorts out.
