Detailed Implementation
[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
[0037] Example: A tobacco grading platform, such as Figure 1-8 As shown, the tobacco grading platform includes a waste receiving box 1, a screen 6, a feeding hopper 2, a movable door, a drive mechanism 9, and support legs 3. Four support legs 3 are provided, arranged in a rectangular pattern and fixed below the waste receiving box 1. The waste receiving box 1 contains a receiving cavity 101 and a receiving cavity. A baffle is installed between the receiving cavity 101 and the receiving cavity, and the baffle is fixed to the inner wall of the waste receiving box 1. The top of the receiving cavity 101 is open, while the top of the receiving cavity is closed. The screen 6 is located at the top of the receiving cavity 101.
[0038] Preferably, the screen 6 is a plastic screen 6 and has a certain degree of elasticity.
[0039] Plastic mesh screens are inexpensive and have some elasticity, making it easy to shake off solid impurities such as dust, broken leaves, and mud.
[0040] The hopper 2 is located at the bottom of the waste receiving box 1. The hopper 2 is connected to the waste receiving box 1 and isolated by a movable door. Preferably, the hopper 2 is made of stainless steel and has a smooth inner surface, which facilitates the downward movement of impurities.
[0041] The drive mechanism 9 is located within the receiving cavity and is used to drive the movable door to open downwards. The movable door is located between the waste receiving box 1 and the discharge hopper 2. The movable door includes a first movable door 81 and a second movable door 82, which are arranged side by side and located on the left and right sides inside the waste receiving box 1, respectively. The side of the first movable door 81 opposite to the side of the second movable door 82 is rotatably connected to the inner wall of the waste receiving box 1, and the side of the second movable door 82 opposite to the side of the first movable door 81 is rotatably connected to the inner wall of the waste receiving box 1. The drive mechanism 9 is used to drive the first movable door 81 and the second movable door 82 to rotate downwards.
[0042] Preferably, both the first movable door 81 and the second movable door 82 are provided with protruding strips 11, which are located on the opposite side of the first movable door 81 relative to the second movable door 82 and on the opposite side of the second movable door 82 relative to the first movable door 81. A rotating shaft 12 passes through the protruding strip 11, and both ends of the rotating shaft 12 are fixed to the inner wall of the waste receiving box 1.
[0043] In the above technical solution, when the tobacco leaves are placed on the screen 6, small solid impurities such as dust, broken leaves, and mud will pass through the screen 6 and enter the receiving chamber 101 inside the waste receiving box 1, and fall onto the movable door, thereby achieving the collection of solid impurities. When the receiving chamber 101 is full of impurities or the waste receiving box 1 needs to be cleaned, the first movable door 81 and the second movable door 82 can be driven downward synchronously by the drive mechanism 9. At this time, the movable door opens downward, and the impurities enter the discharge hopper 2.
[0044] Preferably, the bottom of the hopper 2 is provided with a discharge port 4, and multiple buckles 5 for securing garbage bags are fixed on the outside of the discharge port 4, with the multiple buckles 5 wrapped around the discharge port 4.
[0045] In the above technical solution, when cleaning solid impurities, a garbage bag can be placed over the discharge port 4. This way, after the solid impurities enter the discharge hopper 2 and are discharged through the discharge port 4, they will fall into the garbage bag for centralized collection, making it simple and convenient to use. When the garbage bag is placed over the discharge port 4, the bag opening can be secured with the buckle 5 to prevent solid impurities from falling outside the garbage bag.
[0046] Reference Figure 1-8The drive mechanism 9 is located above the first movable door 81 and the second movable door 82. The drive mechanism 9 includes a cylinder 901, a first connecting rod 902, a second connecting rod 903, a third connecting rod 904, a fourth connecting rod 905, a first turntable 906, a second turntable 907, a third turntable 908, a first fixed plate 909, and a second fixed plate 910. The cylinder 901, the first turntable 906, the second turntable 907, and the third turntable 908 are all rotatably connected to the inner wall of the waste receiving box 1. The installation height of the cylinder 901, the first turntable 906, and the second turntable 907 decreases from high to low, while the second turntable 907 and the third turntable 908 are at the same installation height. The connection point between the first turntable 906 and the inner wall of the waste receiving box 1 is located on the centerline between the connection point of the second turntable 907 and the inner wall of the waste receiving box 1, and between the connection point of the third turntable 908 and the inner wall of the waste receiving box 1. One end of the first connecting rod 902 is rotatably connected to the first turntable 906, and the other end is rotatably connected to the second turntable 907. One end of the second connecting rod 903 is rotatably connected to the first turntable 906 and the piston of the cylinder 901, and the other end is rotatably connected to the third turntable 908. The middle part of the first turntable 906 is rotatably connected to the inner wall of the waste receiving box 1, and both ends are rotatably connected to the first connecting rod 902 and the second connecting rod 903, respectively. One end of the third connecting rod 904 is rotatably connected to the second turntable 907, and the other end is rotatably connected to the first fixed plate 909. One end of the fourth connecting rod 905 is rotatably connected to the third turntable 908, and the other end is rotatably connected to the second fixed plate 910. The first fixed plate 909 and the second fixed plate 910 are respectively fixed to the top of the first movable door 81 and the second movable door 82 and are respectively close to the protrusions 11 on the first movable door 81 and the second movable door 82. The rotatable connection between the second turntable 907 and the inner wall of the waste receiving box 1 is located at one end of the second turntable 907. The rotatable connections between the first connecting rod 902 and the inner wall of the waste receiving box 1, and the rotatable connections between the third connecting rod 904 and the inner wall of the waste receiving box 1, are located on opposite sides of the other end of the second turntable 907. The rotatable connections between the third turntable 908 and the inner wall of the waste receiving box 1, the third turntable 908 and the second connecting rod 903, and the third turntable 908 and the fourth connecting rod 905 form a triangle. The distance between the rotatable connection between the third turntable 908 and the second connecting rod 903 and the rotatable connection between the third turntable 908 and the inner wall of the waste receiving box 1 is greater than the distance between the rotatable connection between the third turntable 908 and the second connecting rod 903 and the fourth connecting rod 905.
[0047] Preferably, when the first movable door 81 and the second movable door 82 are closed, that is, when the first movable door 81 and the second movable door 82 are parallel to the horizontal plane, the top surfaces of the first movable door 81 and the second movable door 82 are in contact with the bottom surface of the baffle. In this way, the baffle can play a limiting role, preventing the first movable door 81 and the second movable door 82 from rotating too much when closing, thereby ensuring that the first movable door 81 and the second movable door 82 can only rotate downwards to open, and will not rotate upwards.
[0048] Preferably, the waste receiving box 1 is equipped with a button 7, which is used to control the start and stop of the cylinder 901. In this way, when it is necessary to collect solid impurities in the waste receiving box 1, simply press the button 7 to start the cylinder 901, thereby driving the first movable door 81 and the second movable door 82 to open.
[0049] In the above technical solution, when the cylinder 901 is started, the piston inside the cylinder 901 extends and pushes the first turntable 906 to rotate clockwise. Under the drive of the first connecting rod 902 and the second connecting rod 903, the second turntable 907 will rotate counterclockwise, while the third turntable 908 will rotate clockwise synchronously. At this time, under the drive of the third connecting rod 904 and the fourth connecting rod 905, the first movable door 81 and the second movable door 82 will rotate downward and open, so that the material in the receiving chamber 101 enters the feeding hopper 2 and falls into the garbage bag through the feeding port 4.
[0050] In summary, compared with the traditional old-style grading table, this utility model uses a sieve 6 for screening, and a gentle shaking can cause impurities to sink and enter the feed hopper 2, which can improve the purity of professional grading, remove sand and soil, reduce the mixing of non-tobacco substances, solve the problem of the inconvenience of cleaning impurities in the existing flue-cured tobacco grading table, improve the qualified rate of tobacco leaves delivered, and reduce production costs.
[0051] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
