However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0036] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection, including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: choose welding connection for fixed connection and hinge connection for detachable connection.

[0037] Specific implementation method 1: Combination Figure 1-Figure 14 The present embodiment is described. A transparent cover of a tobacco conveyor in the present embodiment comprises a support frame assembly 2, a hinge assembly 3, a frame 4, a transparent cover plate 5 and a support beam 6. The transparent cover plate 5 is mounted on the frame 4. One end of the frame 4 is hinged to the support beam 6 through the hinge assembly 3. The support beam 6 is fixedly mounted on the top of the tobacco conveyor 1 through the support frame assembly 2, and a gap is left between the bottom surface of the support beam 6 and the top surface of the tobacco conveyor 1. No matter how the equipment moves, the support beam 6 remains stationary, and the frame 4 and the transparent cover plate 5 mounted on the support beam 6 also remain stationary. At the same time, if condensed water is generated on the transparent cover plate 5, the condensed water will also flow out through the gap left between the bottom surface of the support beam 6 and the top surface of the tobacco conveyor 1 to prevent the condensed water from dripping onto the tobacco shreds and causing local uneven moisture.

[0038] The number of the support frame assemblies 2 is at least two, and the support frame assembly 2 includes a lower support frame 21 and an upper adjusting member 22. The lower support frame 21 is fixed to one side of the tobacco conveyor 1, that is, a hole is drilled at a suitable position and fixed with bolts. The head of the lower support frame 21 has a waist-shaped groove for adjusting the front and rear position of the upper adjusting member. The upper adjusting member 22 is an L-shaped plate, and waist-shaped holes 23 are processed on both sides of the L-shaped plate. The waist-shaped hole 23 located on the top side of the L-shaped plate is used to adjust the width direction of the support beam 6, and the waist-shaped hole 23 located on the lower side of the L-shaped plate is used to fix the support beam 6 and adjust the upper and lower position directions of the support beam 6. The upper adjusting member 22 is bolted and connected to the support beam 6 and the lower support frame 21 through the waist-shaped hole 23, so that the support beam 6 can be adjusted in three dimensions in space to ensure that the support beam 6 does not contact the tobacco conveyor 1. A buckle handle 43 is provided on the front side of the frame 4.

[0039] The joist 6 is a continuous aluminum alloy profile and has an inverted U-shaped structure. The bottom of the joist 6 is flat. When installed, the joist 6 is inverted on the notch of the tobacco conveyor 1 and maintains a certain distance from the side plate of the tobacco conveyor 1.

[0040] The frame 4 includes an arcuate edge 41 and a straight edge 42, and the straight edge 42 and the arcuate edge 41 are connected to form a four-sided frame structure, that is, it includes two straight edges 42 and at least two arcuate edges 41, the two straight edges 42 are arranged in parallel, and are fixed and welded by the arcuate edges 41, and front and rear edging strips 44 and fixing seats are welded on the two straight edges respectively, the edging strips 44 are higher than the straight edges 42, and a gap is reserved for placing the groove of the transparent cover plate 5; the edging strips 44 have a row of holes for fixing the transparent cover plate 5;

[0041] As a more preferred technical solution, the frame 4 can also be formed by welding or riveting round tubes, square tubes, flat irons, etc.

[0042] The transparent cover plate 5 is made of a transparent and bendable plastic sheet, a high-strength and high-transmittance material, preferably a transparent acrylic plate or a PC plate. The transparent cover plate 5 is bent and inserted into the frame 4, and the transparent cover plate 5 and the frame 4 are connected as a whole using bolts. There are a row of mounting holes on both sides of the transparent cover plate 5; when installing, put one side of the transparent cover plate 5 into the edge strip 44, bend the transparent cover plate 5 along the curved edge 41 of the frame, insert both sides of the transparent cover plate 5 into the mounting grooves of the frame edge strip 44, and use bolts and nuts to fix the cover plate and the frame;

[0043] The hinge assembly 3 includes an upper hinge seat 31, a lower hinge seat 32, a hinge shaft 33, a sliding shaft 34 and an arc groove 35. The upper hinge seat 31 is fixedly installed on the rear side of the frame 4, and the lower hinge seat 32 is fixedly installed on the supporting beam 6. The upper hinge seat 31 and the lower hinge seat 32 are hinged through the hinge shaft 33, and the hinge shaft 33 is fixedly connected to the upper hinge seat 31. A penetrating arc groove 35 is processed on the lower hinge seat 32. The upper hinge seat 31 is fixedly provided with a sliding shaft 34, and the sliding shaft 34 is slidably provided in the arc groove 35. The arc groove 35 is used to limit the hinge flipping trajectory to make the device more stable.

[0044] A more preferred technical solution is that the hinge assembly 3 also includes an energy storage spring, and the two ends of the energy storage spring are fixedly connected to the upper hinge seat 31 and the lower hinge seat 32 respectively. The frame 4 is inverted in the slot of the tobacco conveyor 1. By utilizing the spring energy storage function of the energy storage spring, the frame 4 is tightly buckled in the slot of the tobacco conveyor 1 when closed. After the frame 4 is opened to a certain angle, it automatically bounces to the limit angle and maintains it. That is, the energy storage spring needs to be calculated and verified. After the transparent cover 5 is lifted to a certain angle, it can automatically flip up to the maximum angle and maintain the open state. After the transparent cover 5 is closed downward at a certain angle, it will automatically close completely, and the state is stable when fully closed and fully opened.

[0045] It also includes a retainer 7, which is connected to the hinge assembly 3 and the joist 6 respectively, and is used to lock the opening and closing angle of the frame 4.

[0046] The retainer 7 includes a ratchet 71, a pulley 72, a pawl 73, a fixing seat 74, a threaded rod 75, a limit nut 76, a locking nut 77 and a handle 78. The ratchet 71 and the pulley 72 are fixedly mounted on the hinge shaft 33, and the sides of the ratchet 71 and the pulley 72 are fixedly fitted. The fixing seat 74 is fixedly mounted on the joist 6. The threaded rod 75 is slidably matched with the fixing seat 74 and is arranged parallel to the hinge shaft 33. One end of the threaded rod 75 is fixedly connected to the pawl 73, and the other end of the threaded rod 75 is fixedly connected to the handle 78. The limit nut 76 and the locking nut 77 are respectively threadedly matched with the threaded rod 75, and the limit nut 76 and the locking nut 77 are clamped on the left and right sides of the fixing seat 74. The pawl 73 is connected to the fixing seat 74 through a spring 79.

[0047] The retainer 7 has two use states, namely, an active state and a locked state. When the retainer 7 is in the active state, Fig.10 As shown, one hand holds the handle 78, and the other hand manually rotates the limit nut 76 and the locking nut 77, thereby adjusting the relative positions of the limit nut 76 and the locking nut 77 on the threaded rod 75, so that the pawl 73 is aligned with the pulley 72, and the pawl 73 slides and fits the side wall of the pulley 72, and the hinge assembly 3 can be opened to any angle;

[0048] When the retainer 7 is in the locked state, Fig. 9 As shown, one hand holds the handle 78, and the other hand manually rotates the limit nut 76 and the locking nut 77, thereby adjusting the relative positions of the limit nut 76 and the locking nut 77 on the threaded rod 75, so that the pawl 73 is aligned with the ratchet 71, and the pawl 73 slides and fits the side wall of the ratchet 71. When the locking frame 4 is turned over, the upper articulated seat 31 takes the articulated shaft 33 as the rotation center to realize the rotation relative to the lower articulated seat 32. Since the upper articulated seat 31 is fixedly welded to the articulated shaft 33, the upper articulated seat When the locking frame 4 is flipped upward, the ratchet 71 and the pawl 73 are in a relative sliding state. When the frame 4 is released, the frame 4 has a downward movement tendency under the action of its own gravity. At this moment, the pawl 73 is tightened by the spring 79, so that the ratchet 71 and the pawl 73 are in a clamping state, thereby realizing the locking of the upper hinge seat 31 relative to the lower hinge seat 32 at the opening and closing angle.

[0049] A more preferred technical solution is that the tobacco conveyor 1 can also be replaced by a vibrating trough conveyor, a vibrating screen and an elevator. When installing the vibrating trough conveyor, the support frame assembly 2 and the support beam 6 need to be installed on both sides, and the hinge assembly 3 is installed on the support beam 6 on one side.

[0050] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined, and those skilled in the art can exhaust all possibilities based on the mathematical knowledge of arrangement and combination. Therefore, the present utility model will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present utility model.

[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
