Detailed Description

The present invention will be further explained with reference to the embodiments of the drawings.

As shown in fig. 1 to 5, the fruit screening device comprises a hopper 1 and a roller elevator 2, wherein the hopper 1 is arranged at the feeding end of the roller elevator 2, the fruit screening device also comprises a gradually-variable-pitch roller grader 8, the graded-pitch roller grader 8 comprises a graded pitch-limiting screw 81, a chain 82 and a plurality of roller components, the rolling rod assembly comprises a limiting seat 83, a rolling rod 84, a connecting rod 85 and a rolling block 86, the connecting rod 85 is arranged at two ends of the rolling rod 84, the rolling block 86 is arranged on the connecting rod 85, the connecting rod 85 passes through a sliding groove 87 on the limiting seat 83, the limiting seat 83 is arranged on the chain 82 through a mounting hole 88, the chain 82 is connected with the motor through a chain wheel set and a belt wheel set, two gradual change distance-limiting screws 81 are arranged on the body of the gradual change distance rolling rod grader 8, the two gradual change distance-limiting screws 81 are connected with the motor through a belt wheel group, the rolling blocks 86 at the two ends of the rolling rod 84 are respectively attached to the groove walls of the thread grooves on the two gradually-variable pitch screws 81.

Wherein, roll bar lifting machine 2 is used for promoting the conveying fruit, and gradual change is apart from roll bar grader 8 and is carried out hierarchical screening to fruit.

As shown in fig. 1, an electric control box 3 for controlling the operation of the roller elevator 2 and the gradual-change-pitch roller grader 8 is arranged at the bottom of the roller elevator 2.

When starting this device, at first set up the operation parameter of roller lifting machine 2 and gradual change distance roller grader 8 through operation electric cabinet 3, then start roller lifting machine 2 and gradual change distance roller grader 8 through electric cabinet 3, roller lifting machine 2 promotes the fruit of hopper 1 department and begins the conveying.

As shown in fig. 1, a leveling brush 9 is arranged on the roller lifter 2.

When the fruit is lifted to a position at the flattening brush 9 on the roller elevator 2, the flattening brush 9 flattens the fruit that is raised and piled together.

And a material guide plate 4 is arranged at the joint of the roller lifter 2 and the gradient-pitch roller grader 8.

When the roller elevator 2 lifts and conveys fruits to the transition positions of the roller elevator 2 and the gradual change distance roller grader 8, the fruits are gently conveyed to the feeding end of the gradual change distance roller grader 8 through the guide plate 4, and the guide plate 4 can avoid the phenomenon that the fall between the roller elevator 2 and the gradual change distance roller grader 8 is too large, so that the fruits are broken when falling onto the gradual change distance roller grader 8 from the roller elevator 2.

The pitch of the gradual pitch-limiting screw 81 becomes gradually larger.

After fruits fall on the gradual change pitch roller grader, as the chain 82 is connected with the motor through the chain wheel set and the belt wheel set, the motor drives the chain 82 to move, meanwhile, the gradual change pitch-limiting screw 81 is driven to rotate through the motor and the belt wheel set, the chain 82 drives the roller rod assembly to move through the limiting seat 83, and as the pitch of the gradual change pitch-limiting screw 81 is gradually increased and the roller block 86 of the roller rod assembly is attached to the thread groove of the gradual change pitch-limiting screw 81, while the gradual change pitch-limiting screw 81 rotates, the roller block 86 rotates along with the gradual change pitch-limiting screw, the roller block 86 drives the roller rod 84 to rotate together through the connecting rod 85, namely, the roller rod assembly rotates along with the rotation of the gradual change pitch-limiting screw 81, while the roller rod assembly rotates, due to the guiding effect of the screw 81 on the roller rod assembly, the distance between the roller rod assembly is gradually increased, and meanwhile, the connecting rod 85 slides on the sliding groove 87 on the limiting seat 83 (, so that the distance between the roller bar assemblies gradually increases and the position thereof moves), and the mounting hole 88 on the limiting seat 83 is used for fixing the limiting seat 83 on the chain 82.

The conveying device is located at the bottom of the gradual-change-distance rolling rod grader 8 and preferably comprises a first conveying belt 5, a second conveying belt 6 and a third conveying belt 7, and the first conveying belt 5, the second conveying belt 6 and the third conveying belt 7 are arranged at the bottom of the gradual-change-distance rolling rod grader 8 side by side. The utility model discloses in can be according to the demand that the product was selected separately, can increase to the material conveyer belt that connects of arbitrary quantity to change and select separately the grade.

The fruits fall onto the conveying device in the gaps among the rolling rod assemblies on the gradual-change-distance rolling rod grading machine 8, and the gaps among the rolling rod assemblies are gradually increased from small to large, so that the fruits gradually fall onto the first conveying belt 5, the second conveying belt 6 and the third conveying belt 7 from the gradual-change-distance rolling rod grading machine 8 from small to large, and the fruit grading process is completed; the number of belts of the conveyor can be set by the actual requirements.

The utility model discloses a roller lifting machine 2 will place the fruit on hopper 1 and carry, the effect of filtration and screening at first step, it can make its even gradual change apart from roller grader 8 departments to pave the brush 9 to pave the fruit, stock guide 4 enables fruit to enter into gradual change apart from roller grader 8 departments gently, gradual change limit for distance screw rod 81 pitch on the gradual change apart from roller grader 8 becomes from the coming grow, drive roller 84 parallel movement's in-process forward, the continuous increasement of interval between roller 84, the product constantly falls on ejection of compact conveyer from the space between two roller 84, thereby reach the mesh of selecting separately the size, the utility model discloses carry out the efficient grading to fruit under the condition that can not harm fruit.

The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
