Description

Technical Field

[0001] The invention belongs to the technical field of dust removal equipment, and in particular relates to a unloading sealing shed device. Background Art

[0002] Dust removal systems (such as bag filters and cyclone dust collectors) require a sealed enclosure to operate efficiently. Otherwise, dust escape will reduce dust removal efficiency. During open feeding or unloading, dust escape can result in 0.5% to 3% material loss. A sealed enclosure allows for material recovery while maintaining dust removal effectiveness.

[0003] In the prior art, when materials are loaded and unloaded, a sealing cover is generally set above the unloading position to collect dust during unloading, and most sealing covers are fixed and not easy to adjust. Especially in the case of dump trucks unloading, the sealing cover needs to be set high enough and maintain a sufficient unloading distance from the unloading truck to ensure that the dump truck does not collide with the sealing cover on the top when the dump truck turns over to unload. However, the open space of this sealing cover is too large and the dust removal efficiency is low. Summary of the Invention

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0039] Example

[0040] like Figures 1 to 7 As shown, a sealing shed device for unloading includes a sealing shed arranged on a funnel platform 1, the sealing shed includes vertical poles 7, movable support poles and a shed cloth, the vertical poles 7 and the movable support poles are arranged in a U-shape, a plurality of vertical poles 7 are arranged at a fixed distance on the upper end of the funnel platform 1, the movable support poles include a main movable support pole 8 and a plurality of secondary movable support poles hinged on the main movable support pole 8, and the heights of the plurality of secondary movable support poles increase successively toward the vertical pole 7. The main movable support pole 8 is hinged at the upper end of the funnel platform 1, and the hinge point of the main movable support pole 8 is arranged close to the vertical pole 7, but has a certain distance from the vertical pole 7. The outer side of the vertical pole 7 and the movable support pole is wrapped with a shed cloth. The main movable support pole 8 can be rotated to the funnel platform 1, so that the movable support pole drives the shed cloth to unfold; the main movable support pole 8 can be rotated to the position of the vertical pole 7, so that the movable support pole drives the shed cloth to fold.

[0041] The present invention designs a sealed unloading shed device, in which the heights of several secondary movable support rods increase successively toward the vertical pole 7, so as to realize a compact design and optimize the space after folding. After folding, several secondary movable support rods can be folded against the main movable support rod 8 for storage. The outer sides of the vertical pole 7 and the movable support rod are wrapped with a shed cloth, which is fixed at the vertical pole 7 position and foldable at the movable support rod position. When the main movable support rod 8 is rotated to the funnel platform 1, the movable support rod drives the shed cloth to unfold, realizing fully sealed dust collection; when the movable support rod is rotated to the vertical pole 7 position, the movable support rod drives the shed cloth to fold, opening the dust collection port. This dust collection structure is easy to adjust, and can be folded and used according to the situation, whether it is unloading and loading, or ordinary unloading and feeding.

[0042] like Figures 1 to 19As shown, two vertical rods 7 are provided at a fixed distance apart, and two secondary movable support rods are provided, including a first secondary movable support rod 5 and a second secondary movable support rod 6. A rocker seat 4 is provided at one end of the main movable support rod 8, and a first column 44 is vertically provided on the rocker seat 4. A second column 81 is vertically provided in the middle section of the main movable support rod 8. The first column 44 is hinged to the first secondary movable support rod 5, and the second column 81 is hinged to the second secondary movable support rod 6. Through the first column 44 and the second column 81, the first secondary movable support rod 5 and the second secondary movable support rod 6 can be folded and then sequentially fitted and stored. When folded, the first secondary movable support rod 5 is close to the second secondary movable support rod 6, and the second secondary movable support rod 6 is close to the main movable support rod 8, so as to achieve compact storage (such as Figure 3 and Figure 4 shown).

[0043] Furthermore, when the main movable support rod 8 is positioned horizontally, the height of the first upright post 44 is greater than the height of the second upright post 81. This ensures that the movable support rods can be folded and stored layer by layer. Because the height of the first upright post 44 is greater than the height of the second upright post 81, the first secondary movable support rod 5 can be folded and placed on the surface of the second secondary movable support rod 6. At the same time, the gap between the first and second secondary movable support rods 5, 6 can be folded and stored to accommodate the tent cloth.

[0044] Furthermore, the length of the first secondary movable support rod 5 in the vertical direction is greater than the length of the second secondary movable support rod 6 in the vertical direction (e.g. Figure 1 As shown), the first secondary movable support rod 5 and the second secondary movable support rod 6 are fan-shaped. After folding, when the first secondary movable support rod 5 and the second secondary movable support rod 6 are almost parallel, the height of the first secondary movable support rod 5 is lower than the height of the second secondary movable support rod 6 (as shown). Figure 4 shown).

[0045] like Figure 4 As shown, the height of the main movable support rod 8 after erection is equal to or less than the height of the upright pole 7. That is, the vertical length of the main movable support rod 8 is equal to or less than the vertical length of the upright pole 7. The upright pole 7 is fixed, and the awning at the location of the upright pole 7 is fixed and cannot be folded. This location has the highest height. Therefore, when the main movable support rod 8 is folded, its maximum height does not exceed that of the upright pole 7, thus ensuring a compact layout of the entire dust collection device.

[0046] like Figures 1 to 7As shown, in the present invention, the awning cloth is fixed by a cable tie 10, and the awning cloth includes a first awning cloth 92 arranged on the rear side of the vertical pole 7, a second awning cloth 91 arranged on both sides of the movable support rod, and a third awning cloth 9 arranged on the top of the movable support rod. The second awning cloth 91 and the third awning cloth 9 are folded or unfolded along with the movable support rod.

[0047] like Figures 1 to 19 As shown, in the present invention, the unloading sealing shed device also includes a driving mechanism, which includes a cylinder 2, a connecting rod 25, a hinge shaft 3 and a hinge seat 27. The cylinders 2 are hinged on both sides of the funnel platform 1, and the end of the piston rod 21 of the cylinder 2 is hinged to the connecting rod 25. A hinge seat 27 is provided at the upper end of the funnel platform 1. The hinge shaft 3 is rotatably set on the hinge seat 27. One end of the connecting rod 25 is connected to the hinge shaft 3, and one end of the hinge shaft 3 is connected to the rocker arm seat 4. The connecting rod 25 and the rocker arm seat 4 are staggered at a fixed angle with each other.

[0048] Specifically, the end of the cylinder 2 is hinged to the cylinder base 22, which is fixed to both sides of the funnel platform 1. One end of the piston rod 21 is connected to the connecting rod 25 via a connecting fork 23. One end of the connecting fork 23 is provided with a U-shaped slot 232. Both sides of the connecting fork 23 are provided with first pin holes 233 that communicate with the slot 232. The other end of the connecting fork 23 is provided with a first threaded hole 231. One end of the piston rod 21 is threadedly connected to the first threaded hole 231. One end of the connecting rod 25 is set in the slot 232. One end of the connecting rod 25 is provided with a second pin hole 251. The second pin hole 251 is aligned with the first pin hole 233, and the first latch 24 is inserted into the connecting rod 25 to connect.

[0049] Furthermore, a connecting fork 23 is detachably provided at the end of the piston rod 21, and an avoidance groove 252 is provided on the side of the connecting rod 25 close to the connecting fork 23. The avoidance groove 252 is arranged close to the second pin hole 251 to realize the avoidance operation when the connecting rod 25 rotates, thereby avoiding motion interference and collision between the connecting rod 25 and the connecting fork 23.

[0050] In the present invention, the hinge shaft 3 includes a limiting portion 31. One side of the limiting portion 31 is provided with a first shaft segment 32, a second shaft segment 33, a third shaft segment 34, and a fourth shaft segment 35, each of decreasing diameters. The other side of the limiting portion 31 is provided with a fifth shaft segment 37 and a sixth shaft segment 38, each of decreasing diameters. The first shaft segment 32 is rotatably mounted on the inner wall of the hinge seat 27. The third shaft segment 34 defines a third keyway 36. A mounting seat 26 is provided at one end of the connecting rod 25 and is connected to the third shaft segment 34. A flat washer 28 and a stop nut 29 are provided on the fourth shaft segment 35 to secure the mounting seat 26. A third keyway 36 is provided on the fifth shaft segment 37. The rocker arm seat 4 is connected to the fifth shaft segment 37. A flat washer 28 and a stop nut 29 are provided on the sixth shaft segment 38 to secure the rocker arm seat 4.

[0051] A second axial hole 261 and a second key groove 262 are provided inside the mounting seat 26, and the second axial hole 261 and the second key groove 262 are used to cooperate and be set on the third shaft segment 34; a second connecting hole 41 is provided at one end of the rocker seat 4, and one end of the main movable support rod 8 is inserted into the second connecting hole 41, and a first axial hole 42 and a first key groove 43 are provided inside the rocker seat 4, and the first axial hole 42 and the first key groove 43 are used to cooperate and be set on the fifth shaft segment 37.

[0052] One end of the vertical rod 7 is inserted into the inner wall of the first mounting tube 71 and secured with a locking screw. The first mounting tube 71 is welded to the funnel platform 1. One end of the first secondary movable support rod 5 is inserted into the inner wall of the second mounting tube 51 and secured with a locking screw. One end of the second mounting tube 51 is hinged to the first column 44 via a second latch 52. One end of the second secondary movable support rod 6 is inserted into the inner wall of the third mounting tube 61 and secured with a locking screw. One end of the third mounting tube 61 is hinged to the second column 81 via a third latch 62.

[0053] like Figure 3 As shown, in the present invention, a limiting mechanism 73 is provided at the upper end of the first secondary movable support rod 5. When the first secondary movable support rod 5 rotates to be parallel to the vertical rod 7, the limiting mechanism 73 abuts against the vertical rod 7 to limit the transitional folding of the movable support rod, thereby preventing the secondary movable support rods folded and attached to the main movable support rod 8 from separating from the main movable support rod 8 and tilting toward the vertical rod 7 after the movable support rod is transitionally folded, thus preventing the secondary movable support rods folded and attached to the main movable support rod 8 from detaching from the main movable support rod 8 and tilting toward the vertical rod 7, thus preventing the compact folding from being achieved. At the same time, after the compact folding, when unfolding, Figure 4 to Figure 3 During this unfolding process shown, the secondary movable support rod is always folded and fitted onto the primary movable support rod 8; Figure 3 to Figure 1 During the unfolding process shown in FIG, the secondary movable support rods are gradually unfolded to achieve orderly unfolding. Figure 4 to Figure 3 In the unfolding process shown, the secondary movable support rod is not compactly folded and fits on the main movable support rod 8, resulting in that the overall folding structure is messy and cannot be smoothly unfolded or folded when unfolded.

[0054] like Figure 3 and Figure 4As shown, further, the limiting mechanism 73 includes a cylinder 731 provided on the first secondary movable support rod 5, a sliding post 732 is provided at one end of the cylinder 731, a sleeve 733 is slidably provided on the sliding post 732, and a semicircular elastic block 734 is provided at one end of the sleeve 733. The elastic block 734 can be clamped on the surface of the vertical rod 7. A spring 735 is provided on the sliding post 732, one end of the spring 735 is closely attached to the cylinder 731, and the other end is closely attached to the end surface of the sleeve 733. With this design, when the cylinder 2 is extended to control the flipping of the main movable support rod 8, the secondary movable support rod gradually folds and fits on the main movable support rod 8 until the secondary movable support rod rotates to a vertical state and is parallel to the vertical rod 7. At this time, the elastic block 734 is clamped on the surface of the vertical rod 7 to achieve limited fixation, preventing the secondary movable support rod from excessively flipping. At the same time, if the end position of the cylinder 2 is not accurate enough, even if the stroke of the cylinder 2 has a certain error at the end position, the spring 735 will be compressed a certain distance during the continuous extension of the cylinder 2. At this time, the sleeve 733 is relatively stationary and will not be rigidly connected to the vertical rod 7, causing the vertical rod 7 to be stressed. Conversely, when unfolding, the elastic force will tend to move the secondary movable support rod toward the primary movable support rod 8, ensuring that it is first kept in the folded state, preventing the secondary movable support rod from tipping toward the vertical rod 7 when it is first unfolded, and ensuring smooth deployment.

[0055] like Figure 1 and Figure 2 As shown, the funnel platform 1 is hollow inside and is used for unloading materials. Figure 1 The mid-unloading vehicle enters from direction A and flips over to unload, unloading the material into the funnel platform 1; the material flows down to the bucket lifting system along direction B. The funnel platform 1 is configured as a U-shape, with an annular flow channel inside. The upper inner wall of the funnel platform 1 is provided with a number of dust suction ports 11, and the lower inner wall of the funnel platform 1 is provided with a number of return ports 12 connected to the dust suction ports 11. The outer sides of the return ports 12 are connected to the dust collection pipes, and the return ports 12 are hinged with door panels that can be squeezed open by the material to the inside of the funnel platform 1. When the material vehicle is unloading, the sealed shed is opened, and the shed cloth at the position of the vertical pole 7 is used to remove dust during unloading. After the material is unloaded, the sealed shed is closed. The dust collecting pipe sucks and absorbs the dust. The dust floating after unloading enters the annular flow channel inside the funnel platform 1 from the dust suction port 11. The material accumulates due to its own weight or friction, and flows back to the funnel platform 1 from the reflux port 12 for recycling. The remaining dust is sucked into the dust removal system through the dust collecting pipe outside the reflux port 12.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
