Description
Technical field
The utility model relates to a kind of device for vibration screening, is specifically related to a kind of gradable screening machine.
Background technology
Potato is the fourth-largest cereal crops in the world, and it is of many uses, as manufactured potato chips, French fries, starch, the full powder of snowflake and potato seed etc.The processing enterprise of different potato products is different to the size requirements of potato.The product that large-scale potato non-staple food processing enterprise processes, based on potato chips, potato block and French fries, therefore needs to adopt big-and-middle-sized potato as processing raw material; The processing enterprises such as starch, snowflake Quan Fen then adopt mini potato; Rate that quality due to potato seed depends on that potato goes out " carrying " number, namely potato germinates a little number, so require potato the smaller the better, too little can be whole as seed, and this is than far better as seed after being split by large potato.Therefore, potato Seed company needs to adopt mini potato as the raw material processed.
China is potato planting state maximum in the world, but is not far the power of Potato ring rot bacteria and trade, and its export volume is always little, and one of reason is that especially classification level of processing entirety is backward in follow-up deep processing.At present, China's potato classification mainly by manually carrying out, by the impact of individual eyesight, mood, fatigue and surrounding environment in classification process, cause that the efficiency of classification is low, the difference of sorting greatly, can not actual requirement be met.The domestic existing equipment that can carry out classification to potato is mostly the common apparatus of fruits and vegetables series products classification, and special equipment is little, and is mostly single devices, can not Continuous maching.
Utility model content
The purpose of this utility model is to provide a kind of classifying screen, according to the difference of size, automatically carries out machine automatization sizing screening to potato.
For achieving the above object, the technical solution of the utility model is: classifying screen, comprises the body of rectangle, body secures a vibrating motor, vibrating motor is by belt wheel connecting crank, and crank is connected with sieve nest by elastic link, composition toggle; Sieve nest includes sieve, middle sieve and lower sieve three layers of sieve, sieve has sieve aperture, and the size of sieve aperture reduces from top to bottom successively; Sieve nest is fixed on body by vertical elastic rocking bar, composition elasticity double rocking lever four-bar mechanism.
When adopting technique scheme, by vibrating motor through reducing gear driving crank, drive crank and elastic link composition brace and connecting rod framework, thus band dynamic elasticity double rocking lever four-bar mechanism does round complex vibration, wherein as the reciprocal spinning of potato in the sieve nest drive sieve of one of elasticity double rocking lever four bar.Because in sieve, the size of sieve aperture reduces from top to bottom successively, so the potato that diameter is greater than sieve sieve aperture has in the process been stayed in upper sieve; Diameter is less than sieve sieve aperture and the potato being greater than middle sieve sieve aperture has been stayed in middle sieve, the like.The potato of different size is stayed in respective sieve, thus completes the classification to potato.
Further, the rectangular framework of described body, is welded by rectangular steel pipe.
Further, the below of described lower sieve is provided with a screen tray be fixed on sieve nest; Describedly comprise vertical long elasticity rocking bar and vertical short elasticity rocking bar by vertical elastic rocking bar, described vertical long elasticity rocking bar is fixed on the connecting plate of sieve and middle sieve, and described vertical short elasticity rocking bar is fixed on the connecting plate of lower sieve and screen tray.
Further, described sieve is obliquely installed.Because sieve exists inclination angle, so potato rolls along compass screen surface after staying respective sieve, fall into shunting conveying device downwards, thus complete the categorised collection to classification potato.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model classifying screen embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model classifying screen, comprises body 11, and the rectangular framework of body 11, is welded by rectangular steel pipe.Body 11 secures a vibrating motor 1, and vibrating motor 1 is by belt wheel connecting crank 4, and crank 4 is connected with sieve nest 6 by elastic link 5, composition toggle.Sieve nest 6 includes sieve 7, middle sieve 9 and lower sieve 10 3 layers of sieve.Every layer of sieve is all bolted on sieve nest 6, and sieve has sieve aperture, and the size of sieve aperture reduces from top to bottom successively, is the screen traies being fixed on sieve nest 6 in the below of lower sieve 10.Sieve nest 6 is fixed on body 11 by vertical elastic rocking bar.Wherein vertical elastic rocking bar is divided into vertical long elasticity rocking bar 3 and vertical short elasticity rocking bar 2.Vertical long elasticity rocking bar 3 is fixed on the connecting plate of sieve 7 and middle sieve 9, and vertical short elasticity rocking bar 2 is fixed on the connecting plate of lower sieve 10 and screen tray.Upper end and the sieve nest 6 of vertical long elasticity rocking bar 3 and vertical short elasticity rocking bar 2 are rigidly connected, and lower end and body 11 are rigidly connected and support sieve nest 6, and form two elasticity double rocking lever four-bar mechanisms.
The utility model operationally, by vibrating motor 1 through reducing gear driving crank 4, crank 4 and elastic link 5 is driven to form brace and connecting rod framework, thus band dynamic elasticity double rocking lever four-bar mechanism does round complex vibration, the sieve nest 6 wherein as one of elasticity double rocking lever four bar drives the reciprocal spinning of the potato in sieve.Because in sieve, the size of sieve aperture reduces from top to bottom successively, so the potato that diameter is greater than sieve 7 sieve aperture has in the process been stayed in upper sieve 7; Diameter is less than sieve 7 sieve aperture and the potato being greater than middle sieve 9 sieve aperture has been stayed in middle sieve 9, the like.Because sieve exists inclination angle, so potato rolls along compass screen surface after staying respective sieve, fall into shunting conveying device downwards, thus complete the classification to potato.
Go the potato after soil to be transported to hand picking device, after hand picking goes out sick and wounded potato, rise in classifying screen through elevator; The potato dropping into classifying screen is slipped in upper sieve 7 by feeding mouth, after the screening of multi-layer vibration screening plant, potato is made to stay in respective vibrating screen piece, and roll in people shunting conveying device slideway separately, through the vibrations of vibratory sieve, the surface dust on potato surface is fallen from sieve aperture, reaches the object that secondary removes soil; Potato after classification, can respective weighing and bagging after the conveying of shunting.
Classifying screen adopts the principle of multi-layer vibration screening, and wherein sieve is the critical component of classification processing, can use grid screen or grid sieve.According to different classification requirements, the sieve can changing different grid spacing or different size of mesh opening is sieved.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
