DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4 The utility model provides a technical solution: a seed screening device for pepper planting, comprising a screening box 1 and a feed hopper 2, the feed hopper 2 is arranged above the screening box 1, a feed pipe 3 is connected between the feed hopper 2 and the screening box 1, a fan 4 is installed at the right end of the feed pipe 3, a waste pipe 5 connected to the feed pipe 3 is provided at the left end of the fan 4, and a dust bag 6 is provided at the end of the waste pipe 5.
[0026] When the pepper seeds are screened by the screening device, the pepper seeds with pepper shells and pepper stalks are added into the feed hopper 2. When the pepper shells, pepper stalks and pepper seeds in the feed hopper 2 fall into the feed pipe 3, the fan 4 is started, and the wind force blown by the fan 4 is controlled to be less than the gravity of the pepper seeds. Then, the wind blown by the fan 4 blows the debris lighter than the pepper seeds into the waste pipe 5, and then the debris is discharged into the dust collecting bag 6 by the waste pipe 5 for collection, so as to prevent the debris from floating in the air and falling into the eyes of the staff. Since the debris lighter than the pepper seeds is disposed of in advance, it is beneficial to ensure the subsequent screening quality of the pepper seeds and reduce the trouble of selecting and cleaning the debris in the later stage.
[0027] In this embodiment, a screening frame 9 is provided in the screening box 1, a screen 10 is fixed in the screening frame 9, a rotating shaft 12 rotatably connected to the screening box 1 is provided above the screen 10, and a plurality of beating rods 13 are fixed at the upper and lower ends of the rotating shaft 12. A driving motor 11 is installed on the outside of the screening box 1, and the rotating shaft 12 rotates rightward and passes through the outside of the screening box 1, and the power end of the driving motor 11 is connected to the right end of the rotating shaft 12.
[0028] When the pepper seeds enter the screening box 1, the driving motor 11 starts to work and drives the rotating shaft 12 and the beating rod 13 to rotate. The pepper shells, pepper stalks and pepper seeds are beaten by the beating rod 13, which is conducive to beating down the pepper seeds adhering to the pepper shells and preventing too much pepper seeds from accumulating in the same place of the screen 10, so that the pepper seeds are dispersed on the screen 10, thereby helping to better improve the efficiency of pepper seed screening.
[0029] In this embodiment, groove support plates 15 are fixed to the left and right ends of the inner wall of the screening box 1, and return springs 17 are connected to the left and right sides of the upper and lower ends of the screening frame 9. The ends of the return springs 17 are connected to the groove support plates 15. A material shaking drive component is provided above the screening frame 9, and the material shaking drive component includes a first impact ball 14 and two second impact balls 18. There are four first impact balls 14, and the four first impact balls 14 are fixed one by one on the left and right sides of the upper and lower ends of the rotating shaft 12, and the two second impact balls 18 are fixed one by one on both sides of the upper end of the screening frame 9, and the first impact balls 14 correspond to the second impact balls 18 on the same side.
[0030] When pepper shells, pepper stalks and pepper seeds fall onto the screen 10, the driving motor 11 drives the rotating shaft 12 and the first impact ball 14 to rotate when working, so the first impact ball 14 will continuously impact the second impact ball 18 through its arc surface, and the second impact ball 18 will push the screening frame 9 downward, so the screening frame 9 will compress or stretch the return spring 17, and then the elastic force of the return spring 17 will drive the screening frame 9 to reset upward, and so on, so that the screening frame 9 and the screen 10 will shake up and down, which is conducive to driving the screen 10 to shake and screen the pepper seeds, thereby better improving the screening efficiency of the pepper seeds, and the rotation of the first impact ball 14 and the rotation of the beating rod 13 are driven by the same driving motor 11, which is conducive to reducing the use of the motor, making the screening device more practical.
[0031] In this embodiment, an outer peripheral fixed sleeve of the end of the waste pipe 5 is connected with an external threaded connection sleeve 8, and the bag opening of the dust bag 6 is connected with an internal threaded connection sleeve 7, and the internal threaded connection sleeve 7 is threadedly connected to the external threaded connection sleeve 8.
[0032] By threading the internal threaded connecting sleeve 7 and the external threaded connecting sleeve 8 on the dust bag 6, when the dust bag 6 is full of debris, the internal threaded connecting sleeve 7 and the external threaded connecting sleeve 8 are threadably separated, so that the dust bag 6 can be easily disassembled and the debris in the dust bag 6 can be easily cleaned.
[0033] In this embodiment, guide rods 16 are fixed in the groove support plates 15 , and the screening frame 9 is slidably sleeved with the guide rods 16 .
[0034] When the screening frame 9 shakes up and down, the screening frame 9 slides up and down along the guide rod 16, so the guide rod 16 is used to limit the sliding of the screening frame 9 to prevent the screening frame 9 from shaking in other directions, so as to prevent the first impact ball 14 from failing to hit the second impact ball 18, thereby ensuring the accuracy of the first impact ball 14 hitting the second impact ball 18.
[0035] In this embodiment, the lower end of the screening box 1 is connected to a discharge pipe 19 .
[0036] When the pepper seeds are screened, the pepper seeds are discharged from the screening box 1 through the discharge pipe 19.
[0037] Working principle:
[0038] The pepper seeds with pepper shells and pepper stalks are added into the feed hopper 2. When the pepper shells, pepper stalks and pepper seeds in the feed hopper 2 fall into the feed pipe 3, the wind blown out by the fan 4 blows the debris lighter than the pepper seeds into the waste pipe 5, and then the debris is discharged into the dust bag 6 by the waste pipe 5 for collection. When the pepper seeds enter the screening box 1, the driving motor 11 works and drives the rotating shaft 12, the beating rod 13 and the first impact ball 14 to rotate together, and the pepper shells, pepper stalks and pepper seeds are beaten and dispersed by the beating rod 13. At the same time, the first impact ball 14 will continuously hit the second impact ball 18 through its arc surface, and the second impact ball 18 will push the screening frame 9 downward, so the screening frame 9 will compress or stretch the return spring 17, and then the screening frame 9 will be driven to reset upward by the elastic force of the return spring 17, so that the screening frame 9 and the screen 10 will shake up and down, thereby driving the screen 10 to shake and screen the pepper seeds.
[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
