Screening device for pineapples and screening method thereof

Abstract

The invention discloses a screening device for pineapples and a screening method thereof. The screening device for the pineapples comprises a top plate, a mounting frame is fixedly connected to the lower surface of the top plate, a conveying device is arranged in the mounting frame, two rotating plates are arranged below the top plate, a fixing base is arranged above one side of each rotating plate, a sliding block is connected into each fixing base in a sliding and penetrating mode, supporting rods are arranged on the front surfaces and the back surfaces of the sliding blocks, two hydraulic cylinders are arranged on the front surface of the mounting frame, pushing plates are fixedly connected to one ends of pushing rods, and rotating devices are arranged at the tops of the rotating plates. According to the screening device and the screening method thereof, the arrangement mode that the rotating plates and the hydraulic cylinders cooperate with each other is utilized, the pineapples push the bottoms of the rotating plates, the rotating plates can rotate with the axes of second round rods as the circle centers, the rotating plates drive the bottoms of the supporting rods to move, then the hydraulic cylinders operate to drive the pushing rods to move, and therefore the pineapples can be automatically sorted and collected, a large amount of manpower and material resources are reduced, and sorting of the pineapples is more flexible.

Description

Technical field [0001] The present invention relates to the field of screening, and in particular, to a screening apparatus for pineapple and a screening method thereof. Background technique [0002] Pineapple is originally produced in South America Brazil, Paraguay's Amazon River Basin, and passed from Brazil to China in the 16th century. It has been circulated to the entire tropical area. Its edible part is mainly increasing in the meat, the spiral arrangement is arranged in the outer circumference, and the flowers are usually unsaped. The flowers of the consumed are surrounded by a cavity, and the contained stamens and flower columns are hidden in the cavity. The fiber of the leaves is very tough, which can be supplied, rope, junction, and paper. [0003] In the sale of pineapples, the larger size of pineapple is solder than the smaller pineapple price, which makes it necessary to classify the size of the same pineapple before selling. Because the pineapple is a cylindrical fo...

Problems solved by technology

[0003] In the sale of pineapples, the price of larger pineapples is generally higher than that of smaller pineapples, which makes it necessary to classify the size of the same batch of pineapples before selling. Since pineapples are cylindrical fruits, this Therefore, when measuring the body shape of pineapples, the size of pineapples is generally measured by a vernier caliper, but this method of measuring pineapples one by one will waste a lot of manpower and material resources, and workers need to waste a lot of time. Pineapple is measured, which makes the measurement of pineapple not flexible enough
