With the utility model, the grading transmission belts become more compact and stiff; the grading transmission belts are not transformed caused by downward pressing because of fruit gravity when fruits are transmitted; and the actual distance between the grading transmission belts are the same as designed and can be controlled effectively, so that the fruits can be accurately grouped and screened.
Description
Technical field
The utility model relates to fruit sorting triage techniques, special relevant with a kind of structure-improved of fruit grouping screening device.
Background technology
Along with industry science and technology, fruit grouping screening no longer adopts manual operation.Existing fruit sorting machine is mainly used roller strap clearance-type screening machine.As shown in Figure 1, the groundwork principle of roller strap clearance-type screening machine is to keep certain gap between grading roller 10 and canvas conveyer belt 20, its gap progressively increases, fruit, in canvas conveyer belt 20 transport process, falls into different log washer 30 according to gap length, to reach classification object.
But, there is major defect in the roller strap clearance-type screening machine of this structure:
One, grading roller 10 is different with the direction of motion of canvas conveyer belt 20, grading roller 10 is lateral rotation, canvas conveyer belt 20 is longitudinal rotations, so design will be taken fruit to right-hand member by left end and have difficulty, especially fruit reaches in the time of will falling, the contact-making surface of fruit and canvas conveyer belt 20 very little, is difficult to drive especially, and giving to transmit increases difficulty.
Two, in transport process, fruit all the time with grading roller 10 in Frotteurism, as shown in Figure 2, the frictional force that fruit is subject to grading roller 10 is large, very easily cause fruit surface impaired, affect the quality of fruit, so, the scope of above-mentioned roller strap clearance-type screening machine application is smaller, can only carry out sizing screening to the not easily damaged fruit in some surfaces, as orange, apple and so on, and softer for epidermises such as strawberry, red bayberry, tomato, honey peach, the impaired fruit of easy friction, roller strap clearance-type screening machine just cannot play a role.
For this reason, some producer improves grading roller 10 and canvas conveyer belt 20, improves the smoothness of surface both, reduces friction, in order to reduce the loss percentage of roller strap clearance-type screening machine.Like this, virtually improved the cost of fruit sorting machine, increased the weight of user's burden, and loss percentage cannot reduce to zero, still have the destroyed phenomenon of Some Fruits epidermis.
In view of the above-mentioned problems, roller strap clearance-type screening machine truly has room for improvement, and for this reason, the inventor specializes in a kind of fruit grouping screening device, as shown in Figure 3, comprises platform for placing material 1, transmission mechanism 2, at least two sorting conveyers 4 and adapting tables 5.Transmission mechanism 2 comprises motor and reducing gear.Sorting conveyer 4 has two at least, shown in figure, there are five, form four screening lines, every sorting conveyer 4 is all taken turns (can be also a whole large stepped transmission wheel) on 3 around corresponding stepped transmission, and the spacing of adjacent two sorting conveyers 4 increases gradually along direction of transfer.Sorting conveyer 4 is driven with the motion of same line speed and is carried out sizing screening by transmission mechanism 2.Platform for placing material 1 is positioned at the transmission initial end of sorting conveyer 4.Adapting table 5 is positioned at the below of sorting conveyer 4, and adapting table 5 is roughly vertical with sorting conveyer 4.Adapting table 5 has a plurality of, and concrete number is determined according to minute number of stages, such as there being large, medium and small three kinds of specifications.
During this device work, by motor, provide power, after slowing down, transmission mechanism 2 drives sorting conveyer 4 motions with a suitable rotating speed.By sorting conveyer, 4 drives have just entered while screening line fruit on platform for placing material 1, and the spacing between two sorting conveyers 4 is very little, and fruit can be shelved between two sorting conveyers 4, and static motion relative to sorting conveyer 4.When fruit moves ahead after certain distance, it is large that distance between sorting conveyer 4 becomes, and fruit cannot continue to be shelved on two sorting conveyers 4, thereby drop in corresponding below adapting table 5.For the fruit of different sizes, its drop point is different, just falls in the different region of adapting table 5, thereby realizes grouping screening.
Because adjacent sorting conveyer 4 is relatively static all the time in motion process, the fruit being transmitted is also relative static all the time with sorting conveyer 4 in motion process, transmit easily, and can not cause any damage to fruit surface, this just can all divide into groups to screen to all kinds of fruit such as orange, apple, strawberry, red bayberry, tomato and honey peach.
But, the sorting conveyer 4 of this device is softer, when transmitting fruit, be subject to fruit Action of Gravity Field to produce lower compressive strain, even stretch elongated, make sorting conveyer 4 lax, actual range between sorting conveyer 4 is larger than design, and uncontrollable, thus, easily cause large fruit to fall in advance in adapting table 5, be difficult to realize accurate grouping screening.
Therefore, this device still exists needs improvements, and the inventor studies improvement to this device again, and this case produces thus.
Utility model content
The utility model object is to provide a kind of structure-improved of fruit grouping screening device, accurately to realize grouping screening.
In order to achieve the above object, the technical solution of the utility model is:
A structure-improved for fruit grouping screening device, comprises platform for placing material, transmission mechanism, at least two sorting conveyers and adapting table; Sorting conveyer is upper around the stepped transmission wheel of transmission mechanism, and the spacing of adjacent two sorting conveyers increases gradually along direction of transfer, and sorting conveyer is driven with the motion of same line speed and carried out sizing screening by transmission mechanism; Platform for placing material is positioned at the transmission initial end of sorting conveyer; Adapting table is positioned at the below of sorting conveyer; Sorting conveyer below is rib fixedly.
Described rib is for being interrupted shape, and the rib of interruption is fixed on the below of sorting conveyer.
Adopt after such scheme, the utility model because increased rib sorting conveyer is become more compact, stiffening, when transmitting fruit, sorting conveyer can be because of the lower compressive strain of fruit Action of Gravity Field, actual range between sorting conveyer can be controlled effectively with the same of design, thus, can make fruit realize accurately grouping screening.
