DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 In an embodiment of the utility model, an automatic blueberry packaging and weighing device comprises a hopper 1, a loading port is arranged on one side of the hopper 1, a first conveyor belt 2 is arranged at the loading port, the first conveyor belt 2 is inclined, and a fixed baffle is arranged on the first conveyor belt 2; a screening box 3 is arranged on the other side of the first conveyor belt 2, three screening rollers 4 are arranged in the screening box 3, a plurality of screening holes are arranged on the screening roller 4, and the apertures of the screening holes on the three screening rollers 4 increase successively from right to left; a discharge port is arranged on one side of each screening roller 4, and a slide plate 5 is fixedly connected to each discharge port; a return conveyor belt 11 is arranged on the other side of the screening roller 4, a first motor 12 is fixedly connected to one side of the return conveyor belt 11, and the first motor 12 is rotatably connected with the transmission shaft of the return conveyor belt 11 through a reducer.

[0025] By adopting the above technical solution: when in use, first, a loading port is provided on one side of the hopper 1, and a first conveyor belt 2 is provided at the loading port, and the conveyor belt is inclined. The first conveyor belt 2 will convey the blueberry fruit to the screening box 3, and three screening rollers 4 are provided in the screening box 3. The screening rollers 4 are provided with a plurality of screening holes, and the apertures of the screening holes on the three screening rollers 4 increase from right to left. The screening rollers 4 will evenly screen and sort blueberries of different sizes, and the sorted blueberries are conveyed to the second conveyor belt via the slide plate 5; the setting of the return conveyor belt 11 can convey the fallen and scattered blueberries to the hopper for further screening and sorting.

[0026] In this embodiment, a second conveyor belt 6 is provided at the bottom of each slide plate 5, a third conveyor belt 7 is provided on one side of the second conveyor belt 6, a belt scale 9 is provided on one side of the third conveyor belt 7, and a certain gap is formed between the third conveyor belt 7 and the belt scale 9; a receiving shelf 10 is provided on the other side of the belt scale 9, and a receiving frame corresponding to each belt scale 9 is provided on the receiving shelf 10.

[0027] By adopting the above technical solution: the screened blueberries are conveyed to the third conveyor belt 7 via the slide plate 5 and the second conveyor belt 6. A belt scale 9 is provided on one side of the third conveyor belt 7, and there is a certain gap between the belt scale 9 and the blueberries. When the blueberries are conveyed to the belt scale 9, small-sized blueberries can be screened again, and then weighed, and finally packaged on the receiving shelf 10; thereby ensuring the uniformity of blueberry screening and sorting.

[0028] In this embodiment, fixed baffles are provided on both sides of the first conveyor belt 2, and the fixed baffles are fixedly connected to the base of the hopper 1. A third motor 19 is fixedly connected to one side of the fixed baffle, and the third motor 19 is rotatably connected to the transmission shaft of the first conveyor belt 2 through a reducer.

[0029] By adopting the above technical solution, when the blueberry screening work starts, the first conveyor belt 2 is driven by the third motor 19 to convey the blueberries in the hopper 1 to the screening box 3, and then screened by the screening drum 4; the setting of the baffles on both sides of the first conveyor belt 2 ensures that the blueberries will not fall from both sides during the transmission.

[0030] In this embodiment, the second conveyor belt 6, the third conveyor belt 7, and the belt scale 9 are all fixedly connected to the support base 13. A screening slot 8 is opened in the gap between the third conveyor belt 7 and the belt scale 9 on the support base 13, and a receiving frame is provided at the bottom of the screening slot 8.

[0031] By adopting the above technical solution, the support seat 13 is provided with a screening slot 8 in the gap between the third conveyor belt 7 and the belt scale 9. Because there is a certain gap between the third conveyor belt 7 and the belt scale 9, when the screened blueberries pass through the third conveyor belt 7 to the belt scale 9, the blueberries with very small sizes will be screened out and fall through the screening slot 8 to the receiving frame at the bottom of the screening slot 8, thereby avoiding the problem of blueberries of obviously different sizes being packed together, which affects the later sales.

[0032] In this embodiment, a camera 14 is disposed on the upper portion of the second conveyor belt 6 , and the camera 14 is fixed on a camera bracket.

[0033] By adopting the above technical solution, when a large number of blueberries are screened and conveyed via the second conveyor belt 6, accumulation is inevitable. The setting of the camera 14 can detect the accumulation problem in time, and issue an alarm to deal with it in time.

[0034] In this embodiment, the screening drum 4 is hollow and has a transmission shaft inside. One side of the transmission shaft is fixedly connected to the screening drum 4 and extends to the outside of the screening box 3, and is rotatably connected to the screening box 3 through a bearing. A seat bearing is installed on the other side of the transmission shaft, and the seat bearing is fixedly connected to the screening box 3; a screening box bracket 15 is fixedly connected to the bottom of the screening box 3, a second motor 16 is fixedly connected to one side of the screening box bracket 15, and a pulley 17 is installed on the output shaft of the second motor 16, and two pulleys 17 are provided, and the other pulley 17 is installed on one side of the transmission shaft of the screening drum 4, and the pulleys 17 are connected by a belt 18; the transmission shafts of the three screening drums 4 are all equipped with gears and connected by toothed belt transmission.

[0035] By adopting the above technical solution, one side of the transmission shaft is fixedly connected to the screening drum 4, the transmission shaft extends to the outside of the screening box 3, and is equipped with a pulley 17, and is connected to the pulley 17 on the output shaft of the second motor 16 through a belt 18; since the transmission shafts of the three screening drums 4 are equipped with gears and are connected through toothed belt transmission, the second motor drives the screening drum 4 to rotate while the other screening drums 4 also rotate, and then the blueberries will enter the screening drum 4 from the screening holes of corresponding sizes, and then reach the second conveyor belt 6 for transmission through the slide plate 5, thereby achieving the work of blueberry screening.

[0036] The working principle of the utility model is as follows: when in use, the blueberries in the hopper 1 are first conveyed to the screening box 3 through the first conveyor belt 2, and the blueberries enter the screening drum 4 from the screening holes of relatively large sizes through the rotation screening of the screening drum 4, so as to achieve the purpose of screening and sorting; and then the blueberries are conveyed to the third conveyor belt 7 through the second conveyor belt 6. The arrangement of the camera 14 on the second conveyor belt 6 can effectively avoid the long-term accumulation of blueberries. The screening slot 8 can screen out some blueberries of very small size, and convey them to the belt scale 9 for weighing, and finally arrive at the receiving rack 10 for packaging through the receiving frame; the integrated arrangement of screening, packaging and weighing saves labor and improves work efficiency.
