Technical Field

[0001] The invention relates to the technical field of apple sorting, and in particular to an apple sorting device. Background Art

[0002] As consumers’ requirements for fruit quality continue to increase and the fruit market becomes more standardized and refined, the need for standardized classification of apples has become more urgent. Different sales channels and consumption scenarios have clear requirements for the quality grade of apples, especially the size of apples, which usually need to be classified after picking.

[0003] In the prior art, traditional sorting devices have great defects. For example, most traditional sorting devices are drum screening machines. During use, materials are directly poured from the feed hopper into the drum screening machine for screening. However, due to the one-time feeding, it is easy to cause the sorting machine to be blocked. Therefore, the present invention proposes an apple sorting device to solve the above problem.

[0005] In view of the deficiencies in the prior art, the present invention provides an apple sorting device, in which a rotating plate repeatedly rotates with a cross bar as an axis, and the lower end of the feed hopper is intermittently opened. When the feed hopper is opened, apples fall into the machine body, thereby realizing intermittent feeding, avoiding blockage of the machine body caused by a large number of apples entering at one time, and improving the practicability of the device.

[0028] Furthermore, a feeding mechanism for feeding materials is provided in the feed hopper 3, and the feeding mechanism includes a cross bar 11 rotatably connected between the inner walls at both ends of the feed hopper 3, a rotating plate 10 is fixedly sleeved on the cross bar 11, a rotating rod 13 is rotatably connected between the inner walls at both ends of the feed hopper 3, a cam 12 matched with the rotating plate 10 is fixedly sleeved on the rotating rod 13, and a torsion spring 5 is provided at the rotating connection between the two ends of the cross bar 11 and the feed hopper 3.

[0029] Furthermore, one end of the three drum screens 9 is rotatably connected to the inner wall of the body 1, and the other end of the drum screen 9 passes through the side wall of the body 1 and is rotatably connected thereto. The ends of the three drum screens 9 are fixedly sleeved with sprockets 16, and the three sprockets 16 are transmission connected by chains 17. A motor 4 is fixedly connected to the side wall of the body 1, and the end of the output shaft of the motor 4 is fixedly connected to the end of one of the drum screens 9. The end of one of the drum screens 9 and the end of the rotating rod 13 are fixedly sleeved with a transmission wheel 14, and the two transmission wheels 14 are transmission connected by a belt 15.

[0030] Furthermore, two dampers 8 are fixedly connected to the upper end of the base 1, and the telescopic ends of the two dampers 8 are commonly fixedly connected to a placement plate 7. The lower end of the placement plate 7 and the upper end of the base 2 are elastically connected by two symmetrically arranged springs 6.
