[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0029] In the production process of melon seeds, color sorters are commonly used to remove defective products to improve the quality rate. During sorting, the melon seeds fall along the color sorter's feed ramp, generating dust. This dust is collected by a dust removal mechanism mounted above the feed ramp. However, because existing dust removal mechanisms are fixed, the dust collection range is fixed, which can easily create blind spots.

[0030] This embodiment provides a dust removal device for selecting melon seed color, which can drive the dust collection hood above the feed inclined plate to swing back and forth, solving the technical problem of dust collection blind spots that are easily generated due to the fixed dust collection range.

[0031] See also Figure 1-Figure 2 In this embodiment, a dust removal device for melon seed color includes a bracket 10, a transmission rod 20, a pipe 30 and a rotating shaft 40; the transmission rod 20 is slidably connected to the bracket 10; the pipe 30 is rotatably connected to the bracket 10, a dust cover 31 is provided on the pipe 30, the pipe 30 is slidably connected to the transmission rod 20, and the reciprocating movement of the transmission rod 20 along the axial direction of the pipe 30 can drive the pipe 30 to swing back and forth; the rotating shaft 40 is rotatably arranged inside the pipe 30, and the rotating shaft 40 is slidably connected to the transmission rod 20, and the rotation of the rotating shaft 40 can drive the transmission rod 20 to reciprocate along the axial direction of the pipe 30.

[0032] By adopting the technical solution of this embodiment, the rotation of the rotating shaft 40 drives the dust collection cover 31 on the pipe 30 to swing back and forth, which can expand the dust collection range and avoid the dust collection blind spot caused by the fixed dust collection range.

[0033] In this embodiment, the bracket 10 is arranged on the outside of the feed inclined plate 50, and the feed inclined plate 50 is used to guide the melon seeds to slide downward. A support plate 11 is fixedly connected to the top of the bracket 10, and the support plate 11 is arranged parallel to the feed inclined plate 50. At the same time, the plane where the support plate 11 is located is arranged parallel to the axis of the pipeline 30. A longitudinal slide groove 12 is also provided on the support plate 11, and the slide groove 12 is arranged parallel to the axis of the pipeline 30.

[0034] In this embodiment, the transmission rod 20 is constructed as a longitudinal round straight rod. The transmission rod 20 is passed through the slide groove 12 on the support plate 11, and the transmission rod 20 and the support plate 11 are arranged vertically. The transmission rod 20 as a whole is perpendicular to the axis of the pipe 30. Positioning nuts 21 are screwed on the transmission rod 20 on the upper and lower sides of the support plate 11. The two positioning nuts 21 limit the transmission rod 20 inside the slide groove 12 and keep the transmission rod 20 perpendicular to the slide groove 12. The transmission rod 20 can slide along the longitudinal direction of the slide groove 12.

[0035] In this embodiment, the pipe 30 is entirely mounted above the feed inclined plate 50. The pipe 30 is arranged along the width direction of the feed inclined plate 50, and the pipe 30 is kept parallel to the feed inclined plate 50. At the same time, the axis of the pipe 30 is kept parallel to the slide groove 12 on the support plate 11. A plurality of dust collection hoods 31 are arranged at intervals along the axial direction of the pipe 30. The dust collection hoods 31 are arranged above the feed inclined plate 50. The dust collection hoods 31 are fixedly connected to the pipe 30, and the dust collection hood 31 is communicated with the inner cavity of the pipe 30. A connector 32 is fixedly connected to the middle part of the pipe 30 along the axial direction of the pipe 30. The connector 32 is used to connect to a negative pressure generating unit. The negative pressure generating unit includes a dust collecting box. The negative pressure generating unit is used to form a negative pressure environment inside the pipe 30, so that the dust generated when the melon seeds slide down the feed inclined plate 50 is sucked into the pipe 30 through the dust collection hood 32, and then flows into the dust collecting box through the connector 32.

[0036] In addition, both ends of the pipe 30 are rotatably connected to the bracket 10, and one end of the pipe 30 extends out of the outside of the bracket 10 to form a connecting section. The connecting section is located below the support plate 11. A limiting groove 33 is provided on the connecting section of the pipe 30. The limiting groove 33 is arranged at an angle relative to the axis of the pipe 30. The transmission rod 20 passes through the limiting groove 33, and the transmission rod 20 can slide inside the limiting groove 33.

[0037] In this embodiment, the rotating shaft 40 is constructed as a longitudinal solid round rod. The rotating shaft 40 is arranged inside the pipe 30 and is coaxial with the pipe 30. Two sealing covers 43 are fixedly connected in the inner cavity of the pipe 30. The rotating shaft 40 is rotatably arranged on the sealing cover 43. The sealing cover 43 supports the rotating shaft 40. A guide groove 42 is opened on the outer wall of the rotating shaft 40, and the guide groove 42 extends along the circumference of the rotating shaft 40. The guide groove 42 is a closed-loop structure. The plane where the guide groove 42 is located is arranged at an angle to the axis of the rotating shaft 40. The inner end of the transmission rod 20 can be slidably engaged in the guide groove 42. A support plate is fixedly connected to the outer side of the bracket 10. The driving unit 41 is fixedly connected to the support plate. The output end of the driving unit 41 is transmission-connected to the rotating shaft 40. As an example, the driving unit is a motor, and the output end of the motor is fixedly connected to the rotating shaft 40.

[0038] It should be noted that when the driving unit 41 drives the rotating shaft 40 to rotate, the guide groove 42 is used to slide and engage with the transmission rod 20, so as to drive the transmission rod 20 to slide back and forth along the slide groove 12 on the support plate 11. At the same time, the limiting groove 33 is used to slide and engage with the transmission rod 20. When the transmission rod 20 slides back and forth along the slide groove 12, it can drive the pipe 30 to swing back and forth around the axis of the rotating shaft 40, thereby driving the dust hood 31 to swing back and forth.

[0039] It should be understood that the rotating shaft 40 passes through the interior of the pipe 30, and the rotating shaft 40 itself occupies part of the inner space of the pipe 30, so that the air flow rate inside the pipe 30 is accelerated, which can improve the dust collection efficiency to a certain extent.

[0040] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
