Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] Reference Figures 1 to 4As shown, in one embodiment of the present invention, a bulk material conveying device includes a sealed box 1 and a scale conveyor 2. The scale conveyor 2 is located in the sealed box 1. The sealed box 1 includes a tail sealing cover 11, a middle sealing box 12 and a head sealing cover 13.

[0031] The middle section sealing box 12 includes a main keel 121 extending along the conveying direction of the scale conveyor 2. There are two main keels 121 arranged at intervals. Multiple ribs 122 are provided between the two main keels 121. The multiple ribs 122 are arranged at intervals along the extension direction of the main keel 121.

[0032] It also includes multiple U-shaped frames 123 arranged at intervals along the extension direction of the main keel 121. The U-shaped frames 123 are mounted on the two main keels 121. The U-shaped frames 123 correspond one-to-one with the ribs 122. The ribs 122 and the corresponding U-shaped frames 123 form a rectangular frame, through which the scale conveyor 2 passes.

[0033] Four enclosure plates 124 are provided between two adjacent rectangular frames. The four enclosure plates 124 correspond to the four sides of the rectangular frames. The four enclosure plates 124 enclose the tube body, and the two ends of the tube body are respectively connected to the rectangular frames.

[0034] The two rectangular frames at the very end of the main keel 121 are connected to the tail sealing cover 11 and the head sealing cover 13 respectively; the tube body adjacent to the tail sealing cover 11 is provided with a feed inlet 125, and the head sealing cover 13 is provided with a discharge outlet 131.

[0035] In use, bulk materials are fed into the feed inlet 125, and the scale conveyor 2 transports the bulk materials to the discharge outlet 131. Except for the feed inlet 125 and the discharge outlet 131, the tail sealing cover 11, the middle sealing box 12 and the head sealing cover 13 are all sealed to reduce dust diffusion.

[0036] The intermediate sealing box 12 is based on the main keel 121. Ribs 122 and U-shaped frames 123 are fixed on the main keel 121. The ribs 122 and U-shaped frames 123 correspond to each other to form a rectangular frame. Multiple tubes are set between the rectangular frames so that the multiple tubes and the rectangular frame are connected in series for sealing, thus forming the intermediate sealing box 12. Based on this, the surrounding plate 124, ribs 122 and main keel 121 can be processed separately and then assembled on site. The processing and transportation difficulty is greatly reduced. Moreover, the surrounding plate 124, ribs 122 and U-shaped frames 123 can be used with scale conveyors 2 of different transport lengths, without the need for too many customized parts, thus reducing equipment costs.

[0037] Specifically, the main keel 121 is bent into a horizontal section and an inclined section. The inclined section is inclined upward. Therefore, the assembled middle section sealing box 12 is also bent upward, and the head sealing cover 13 is located at the upper end of the middle section sealing box 12.

[0038] In this embodiment, the feed port 125 is opened at the top of the tube body, and the feed port 125 can be provided on several tube bodies near the tail sealing cover 11 to expand the feed area; or, the upper surrounding plate 124 in the tube body can be removed to form the feed port 125.

[0039] In this embodiment, the U-shaped frame 123 includes a crossbeam 1231 and two longitudinal beams 1232. The crossbeam 1231 connects the two longitudinal beams 1232, and the longitudinal beams 1232 are fixedly connected to the main keel 121.

[0040] A reinforcing plate can be installed between the longitudinal beams 1232 of two adjacent U-shaped frames 123, and a reinforcing plate can also be installed between the two longitudinal beams 1232 of the same U-shaped frame 123 to improve the strength of the middle sealing box 12. At the same time, the reinforcing plate can be used to support the scale conveyor 2.

[0041] In this embodiment, the longitudinal beam 1232 is fixed to the top surface of the main keel 121, the top surface of the rib 122 is flush with the top surface of the main keel 121, and the surrounding plate 124 corresponding to the rib 122 is located between two adjacent ribs 122. In this way, the lower end of the surrounding plate 124 connected to the longitudinal beam 1232 will be bent and contact the top surface of the main keel 121 and extend towards the rib 122, enclosing the surrounding plate 124 located between the two ribs 122. Alternatively, it can be enclosed by a part of the main keel 121 with the surrounding plate 124 located between the two ribs 122, thereby completing the seal.

[0042] In this embodiment, the surrounding plate 124 located between the two ribs 122 is flush with the top surface of the ribs 122, and the inner bottom surface of the sealed box 1 is relatively flat. By controlling the size of the scales of the scale conveyor 2, the inner bottom surface of the sealed box 1 can contact the scales, thereby allowing the scales to scrape the loose material on the inner bottom surface of the sealed box 1 and avoid the accumulation of loose material.

[0043] Preferably, a return material arc plate 111 is provided in the tail sealing cover 11. The return material arc plate 111 is adapted to the end of the scale conveyor 2. The scales on the scale conveyor 2 can contact the concave surface of the return material arc plate 111.

[0044] After the scales scrape the loose material on the enclosure plate 124, as the scale conveyor 2 runs, the scales will move to the return arc plate 111, thereby pushing the loose grain up along the return arc plate 111 until the scales flip up and the loose grain falls between the two scales, thus returning the loose material to the scale conveyor 2 and continuing to be conveyed to the discharge port 131.

[0045] More preferably, an elastic sheet can be provided at the end of the scale plate. The elastic sheet can contact the surrounding plate 124 and the return material arc plate 111 to better scrape the loose material.

[0046] In this embodiment, a turntable 112 is provided at the end of the tail sealing cover 11 away from the middle sealing box 12. A screw 113 is inserted through the turntable 112. The screw 113 extends into the interior of the tail sealing cover 11 and is connected to the return material arc plate 111. Rotating the turntable 112 allows the screw 113 to move horizontally, so that the return material arc plate 111 can move closer to or away from the scale conveyor 2, thereby controlling the distance between the return material arc plate 111 and the scale plate, and ensuring that the elastic film can contact the return material arc plate 111.

[0047] In this embodiment, baffles 114 are provided on both sides of the return material arc plate 111 along its bending direction.

[0048] In this embodiment, the inner wall of the tail sealing cover 11 is provided with a guide rail 115, and the baffle 114 is provided with a guide wheel 116. The guide wheel 116 and the guide rail 115 are slidably engaged so that the return material arc plate 111 can move horizontally, which facilitates the adjustment of the position of the return material arc plate 111.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
