Technical Field

[0001] The invention relates to the technical fields of material collection, transportation, environmental engineering, etc., and in particular to a double-force spiral transportation mechanism. Background Art

[0002] In environmental engineering, it is often necessary to remove pollutants, or collect and transport substances that may have an adverse impact on the environment. This type of construction device is often equipped with a spiral transport mechanism, an auger. The auger can transport the material in contact with the auger to one end of the spiral plate and output it from there through the rotation of the spiral plate (i.e., spiral blade) of the auger. In the process of using the auger to transport pollutants or harmful substances, it is necessary to control the diffusion of materials to avoid the expansion of the impact range of pollutants or toxic and harmful substances.

[0003] However, the existing auger only has a spiral plate structure. In the process of collecting and transporting materials, the disturbance of the spiral plate to the materials is likely to cause the materials to be scattered and diffused around, and the materials cannot be well gathered, which is likely to cause the expansion of the influence range of pollutants or toxic and harmful substances. Therefore, it is necessary to design a transport mechanism that can effectively control the diffusion range of the collected or transported materials in the case of unavoidable disturbance, so as to avoid the diffusion of pollutants and harmful substances during the transport process.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: a double-force screw conveying mechanism is disclosed, which can be used for collecting and conveying bulk or fluid materials, fluid substances or mixtures, so that the materials can be better gathered and not easily scattered and spread outside the conveying mechanism, thereby ensuring the material conveying effect and avoiding the spread of pollutants or toxic and harmful substances during the conveying process. Specifically:

[0017] (1) The double-force spiral conveying mechanism adds inner blades to the spiral plate of the auger body. When the spiral plate rotates in the forward direction in the bulk or fluid material, it will generate mechanical force on the material particles: the inner blades apply a driving force toward the central axis of the spiral plate to the material particles, so that the material particles generate a force to move toward the central axis of the spiral plate; the spiral plate applies a transfer force toward its output end to the material, so that the material generates a transfer movement. Based on the above mechanical forces, the double-force spiral conveying mechanism can be used in a collection and conveying device for bulk or fluid materials.

When the spiral plate rotates in the forward direction, the outer blade drives and guides the material at the discharge end to move away from the central axis of the spiral plate, thereby facilitating the discharge of the material from the discharge end of the spiral plate.

[0019] (3) In the preferred embodiment, the spiral plate is arranged in the packaging shell, and the gap between the packaging shell and the spiral plate is small, so that a pressure difference can be generated inside and outside the packaging shell, thereby generating fluid power, prompting the fluid material outside the packaging shell to be sucked in through the feed port, further reducing the possibility of material diffusion. The spiral plate with the packaging shell can be used in a fluid material collection and transportation device. Under the action of the pressure difference between the inside and outside of the packaging shell, its effect of preventing material diffusion can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0030] It should be noted that, in the description of the present invention, the directions or positional relationships indicated by terms such as “inside”, “outside”, “up”, “down”, “left”, “right”, “front” and “back” are based on the positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] like Figures 1 to 8 As shown, a double-force spiral transport mechanism includes an inner blade 2 and a spiral plate 1 as an auger body, wherein the inner blade 2 is fixedly installed between adjacent threads of the spiral plate 1, and the two side edges of the inner blade 2 are respectively connected to the two adjacent threads of the spiral plate 1, and the two ends of the inner blade outer edge 21 are respectively arranged close to the outer edges of the two adjacent threads, and the inner blade 2 extends from the inner blade outer edge 21 in a direction close to the central axis of the spiral plate 1, and the inner blade 2 is provided in a plurality and distributed around the central axis of the spiral plate 1; a fixed plane extending from the central axis of the spiral plate 1 in any direction is used as a reference plane ( Figure 3 The dashed box and Figure 4 The dashed lines in the middle represent reference planes), when the spiral plate 1 rotates in the positive direction (such as Figure 1 and Figure 2 As shown in the direction of the arrow, when the spiral plate 1 rotates in the positive direction, that is, the spiral plate 1 rotates around its central axis to drive the material to move toward its discharge end, during the process of the inner blade 2 passing through the reference plane, the minimum distance between the intersection line of the inner blade 2 and the reference plane and the central axis of the spiral plate 1 gradually decreases. That is, when the spiral plate 1 rotates in the positive direction, the inner blade 2 guides the material on the outer edge of the spiral plate 1 to move toward the central axis of the spiral plate 1.

[0032] The double-force spiral transport mechanism adds inner blades 2 to the spiral plate 1 of the auger body. When the spiral plate 1 rotates in the bulk or fluid material along the positive direction, it will generate mechanical force on the material particles: the inner blades 2 apply a driving force toward the central axis of the spiral plate 1 to the material particles, so that the material particles generate power to move toward the central axis of the spiral plate 1; the spiral plate 1 applies a transfer force toward its output end to the material, so that the material generates a transfer movement. Based on the above mechanical forces, the double-force spiral transport mechanism can be used for the collection and transportation device of bulk or fluid materials. Under the joint action of the inner blades 2 and the spiral plate 1, the material is better gathered during the collection and transportation process, and is not easy to be scattered and diffused outside the transport mechanism, thereby ensuring the material transportation effect and avoiding the diffusion of pollutants or toxic and harmful substances during the transportation process.

[0033] The cylinder formed by the motion trajectory of the inner edge line of the inner blade 2 when the spiral plate 1 rotates in the positive direction is used as the inner cylinder, the cylinder formed by the motion trajectory of the outer edge 21 of the inner blade when the spiral plate 1 rotates in the positive direction is used as the outer cylinder, the cylinder formed by the motion trajectory of the inner edge line of the spiral plate 1 when the spiral plate 1 rotates in the positive direction is used as the core cylinder, and the cylinder formed by the motion trajectory of the outer edge of the spiral plate 1 when the spiral plate 1 rotates in the positive direction is used as the surface cylinder. The double-force spiral transport mechanism adopts the above structure. By changing the relative size between the radius of the inner cylinder and the radius of the core cylinder and between the radius of the outer cylinder and the radius of the surface cylinder, the strength relationship between the driving action of the inner blade 2 and the transport action of the spiral plate 1 can be changed, thereby adjusting the performance of the double-force spiral transport mechanism.

[0034] Specifically, the inner cylindrical surface, outer cylindrical surface, core cylindrical surface and surface cylindrical surface can all be cylindrical surfaces, or non-cylindrical surfaces with variable radial dimensions, that is, the radii of certain cross-sectional circles intercepted at different positions of the cylindrical surface can be different.

[0035] Specifically, the inner blade 2 is configured as a unidirectional curved plate.

[0036] Specifically, the plurality of inner blades 2 fixedly mounted on the spiral plate 1 are evenly arranged along the outer edge spiral direction of the spiral plate 1. The plurality of inner blades 2 are evenly arranged along the outer edge spiral direction of the spiral plate 1 to ensure that the inner blades 2 evenly provide the material with power to move toward the central axis of the spiral plate 1, thereby ensuring the gathering effect of the material.

[0037] Specifically, the spiral plate 1 includes a plurality of thread segments 11 arranged axially along the spiral plate 1, each of the thread segments 11 includes a circle of threads, and a plurality of inner blades 2 (for example, Figure 1 and Figure 2 As shown, three inner blades 2 are fixedly installed between the two threaded sections 11).

[0038] Specifically, the spiral plate 1 and the inner blades 2 are configured as an integrated structure.

[0039] Specifically, the end of the spiral plate 1 to which the material conveying direction points when the spiral plate 1 rotates in the forward direction is used as the discharge end, and the discharge end is fixedly mounted with an outer blade 5, a side of the outer blade 5 is fixedly connected to the discharge end, and the outer edge 51 of the outer blade is arranged close to the outer edge of the thread of the discharge end, and the outer blade 5 extends from the outer edge 51 of the outer blade toward the direction close to the central axis of the spiral plate 1, and the outer blade 5 is provided in plurality. When the spiral plate 1 rotates in the forward direction, during the process of the outer blade 5 passing through the reference plane, the minimum spacing between the intersection line of the outer blade 5 and the reference plane and the central axis of the spiral plate 1 gradually increases. When the spiral plate 1 rotates in the forward direction, the outer blade 5 drives and guides the material at the discharge end to move away from the central axis of the spiral plate 1, so that the material can be discharged from the discharge end of the spiral plate 1 conveniently.

[0040] Specifically, the outer blades 5 are configured as curved plates, and the plurality of outer blades 5 fixedly mounted at the discharge end are evenly arranged along the outer edge spiral direction of the discharge end (for example, the outer blades 5 may be configured as three, four or five, etc.).

[0041] Specifically, Figure 5 As shown, it also includes a rotating shaft 3 arranged on the central axis of the spiral plate 1, and the rotating shaft 3 is fixedly connected to the spiral plate 1.

[0042] Specifically, Figure 5 As shown, the spiral plate 1 further comprises end circular plates 4 fixedly arranged at both ends of the spiral plate 1, the end circular plates 4 are fixedly connected to the rotating shaft 3, the end circular plates 4 connected to the discharge end are provided with a first discharge port 41 for discharging materials, and the outer blades 5 are fixedly mounted on the side of the end circular plate 4 away from the spiral plate 1. The first discharge port 41 can be set to any shape, and the material transferred to the discharge end by the spiral plate 1 through the first discharge port 41 can be transferred from one side of the end circular plate 4 to the other side to avoid the end circular plate 4 affecting the discharge.

[0043] Specifically, the end circular plate 4 is configured as a circular plate coaxially arranged with the central axis of the rotating shaft 3 , and the plurality of outer blades 5 are evenly arranged along the circumference of the end circular plate 4 .

[0044] Specifically, Figure 7 and Figure 8As shown, it also includes a packaging shell 6, the spiral plate 1 is horizontally installed in the packaging shell 6, one end of the rotating shaft 3 passes through the packaging shell 6 to connect the rotating shaft driving device, the rotating shaft 3 is rotatably connected to the packaging shell 6, and the packaging shell 6 is provided with a feed port 62 for feeding and a second discharge port 61 for discharging, and the second discharge port 61 is arranged close to the first discharge port 41 and communicated with the first discharge port 41. The gap between the packaging shell 4 and the spiral plate 1 is small, so that a pressure difference can be generated inside and outside the packaging shell 6 to generate fluid power, so that the fluid material outside the packaging shell 6 is sucked in through the feed port 62, further reducing the possibility of material diffusion. The spiral plate 1 with the packaging shell 6 can be used for the collection and transportation device of fluid materials. Under the action of the pressure difference between the inside and outside of the packaging shell 6, its function of preventing material diffusion can be improved.
