DETAILED DESCRIPTION
[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.
[0025] The utility model provides a dust removal device for a red date screening machine, such as Figures 1 to 3 As shown, it includes a machine body 1, a feed roller 2 rotatably arranged on the machine body 1, and a feed belt 3 arranged on the feed roller 2, a material receiving frame 4 is arranged on one side of the machine body 1, a discharge port 5 is arranged at the bottom end of the material receiving frame 4, a dust hood 6 is arranged on the inner wall of the material receiving frame 4 away from the feed belt 3, an exhaust pipe 7 connected to the dust hood 6 is arranged on the material receiving frame 4, an exhaust motor 8 is arranged on the top of the exhaust pipe 7, a detachable dust accumulation piece 9 is arranged at the bottom of the exhaust pipe 7, and a mesh material baffle plate 10 is arranged on the inner wall of the dust hood 6.
[0026] Furthermore, a long strip-shaped first dust removal pipe 11 is arranged on the inner wall of the material receiving frame 4 on the side close to the conveyor belt 3 , and a plurality of first air outlet pipes 12 are evenly arranged on the first dust removal pipe 11 .
[0027] Furthermore, the receiving frame 4 is symmetrically provided with long strip-shaped second dust removal pipes 13 on the inner walls on both sides close to the first dust removal pipe 11 , and the second dust removal pipes 13 are evenly provided with second air outlet pipes 14 .
[0028] Furthermore, the dust collecting member 9 comprises a funnel-shaped material guide pipe 91 connected to the bottom of the air exhaust pipe 7 and a dust collecting box 92 threadedly connected to the bottom of the material guide pipe 91 .
[0029] Furthermore, the first air outlet pipe 12 is arranged along the horizontal direction.
[0030] Furthermore, the second air outlet pipe 14 is arranged in an inclined upward direction.
[0031] Furthermore, the horizontal plane at which the first dust removal pipe 11 is located is higher than the horizontal plane at which the second dust removal pipe 13 is located.
[0032] Furthermore, the opening direction of the dust hood 6 on the side close to the conveyor belt 3 is inclined downward.
[0033] Furthermore, the horizontal plane at which the bottom end of the dust hood 6 is located is higher than the horizontal plane at which the first dust removal pipe 11 is located.
[0034] Furthermore, the dust box 92 is made of a transparent material.
[0035] When the feeding belt 3 transports the red dates into the receiving frame 4 (it should be noted that the conveyor belt transports the red dates obliquely upward. In actual production, the conveyor belt is evenly provided with push plates so that the red dates can be transported obliquely upward. Since this technical feature is not within the technical scope protected by the present application, it will not be described in detail and will not affect the technical scope actually protected by the present application), the exhaust motor 8 drives the dust hood 6 to exhaust air, and the floating dust on the surface of the red dates is sucked into the exhaust pipe 7, while the red dates are blocked by the mesh baffle plate 10 and will not be sucked into the dust hood 6 (it should be noted that the dust hood 6 is located on the side of the receiving frame 4 away from the conveyor belt, and the red dates transported by the conveyor belt mainly enter the receiving frame 4 from the middle of the receiving frame 4. Therefore, there is a certain distance between the dust hood 6 and the red dates, and the suction provided by the exhaust motor 8 is adjusted to a suitable level so that the suction provided by the dust hood 6 is not strong. The red dates will not all be sucked and adsorbed on the material receiving plate 10, and at the same time, the red dates will continuously fall from the conveyor belt into the material receiving frame 4, so the red dates falling behind will hit the red dates in front, further ensuring that the red dates will not be adsorbed on the material receiving plate 10). While the dust hood 6 is sucking, the first dust removal pipe 11 blows air to one side of the dust hood 6 in a horizontal direction through the first air outlet pipe 12, and the two second dust removal pipes 13 blow air obliquely upward relative to each other through the second air outlet pipes 14, so that the floating dust on the surface of the red dates is further blown to the middle of the material receiving frame 4, and then sucked and removed by the dust hood 6. The red dates that enter the material receiving frame 4 then enter the red date screening body through the opening at the bottom of the material receiving frame 4 for screening; through the mutual cooperation between the dust hood 6, the first dust removal pipe 11 and the second dust removal pipe 13, the technical effect of removing the floating dust on the surface of the red dates and improving the quality of the red dates is achieved.
[0036] By setting the opening of the first air outlet pipe 12 to be horizontal and the opening of the second air outlet pipe 14 to be inclined upward, air is blown to the red dates entering the receiving frame 4, and the floating dust on the surface of the red dates is blown to the middle part of the receiving frame 4, and then further sucked into the exhaust pipe 7 by the dust hood 6, thereby improving the effect of removing the floating dust on the surface of the red dates.
[0037] By providing the guide pipe 91 and the dust box 92, and setting the dust box 92 to be transparent, the dust entering the exhaust pipe 7 enters the dust box 92 through the funnel-shaped guide pipe 91 under the action of gravity. After observing that there is a lot of dust in the dust box 92, the worker can directly turn and remove the dust box 92 and pour out the dust in the dust box 92. The operation is simple and convenient
[0038] By setting the opening of the dust hood 6 to be obliquely downward, and arranging the dust hood 6, the first dust removal pipe 11 and the second dust removal pipe 13 from top to bottom, so that the two second dust removal pipes 13 blow air obliquely upward, the first dust removal pipe 11 blows air in the horizontal direction, and the dust hood 6 sucks upward at the same time, the overall direction of the dust is from bottom to top, and the red dates are from top to bottom under the action of gravity, thereby ensuring the removal effect of the floating dust on the red dates and improving the quality of the red dates.
[0039] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0040] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
