[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0025] In related technologies, funnel boxes employ a touch-sensitive bottom door opening and closing mechanism, which is inconvenient to use. This disclosure provides a funnel box bottom door unit and a funnel box, which can at least partially solve the technical problem of inconvenience caused by the touch-sensitive bottom door opening and closing mechanism.

[0026] The technical solutions of this disclosure are described below with reference to the accompanying drawings and specific embodiments.

[0027] As shown in Figures 1 to 8, the bottom door unit 100 of the funnel box is installed on the box body 200 of the funnel box 1000. The box body 200 of the funnel box 1000 has a material discharge port. The bottom door unit 100 includes a bottom door mechanism 110, a closing drive assembly 120, and an opening drive assembly 130. The bottom door mechanism 110 is installed on the box body 200 and has a covered position for covering the material discharge port and an open position for opening the material discharge port; the closing drive assembly 120 is installed on the box body 200 and connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 is in the covered position; the opening drive assembly 130 is installed on the box body 200 and connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 is in the open position.

[0028] The funnel box 1000 has a discharge port at the bottom of its body 200. Material inside the funnel box 1000 discharges through this discharge port. A bottom door mechanism 110 is mounted on the body 200. The bottom door mechanism 110 can either cover the discharge port, keeping it closed and preventing material from discharging through it, or leave the discharge port open, allowing material to drain through.

[0029] A door closing drive assembly 120 is mounted on the housing 200. The door closing drive assembly 120 is connected to the bottom door mechanism 110 and drives the bottom door mechanism 110 to move, enabling the bottom door mechanism 110 to be in the covered position. A door opening drive assembly 130 is mounted on the housing 200. The door opening drive assembly 130 is connected to the bottom door mechanism 110 and drives the bottom door mechanism 110 to move, enabling the bottom door mechanism 110 to be in the open position.

[0030] As described above, the funnel box bottom door unit 100 has a closing drive assembly 120 for controlling the closing of the bottom door mechanism 110 and an opening drive assembly 130 for controlling the opening of the bottom door mechanism 110. Therefore, the funnel box 1000 with the funnel box bottom door unit 100 can realize the opening and closing of the bottom door mechanism 110 by its own structure, without the need for cooperation with ground facilities. This makes the opening and closing of the bottom door mechanism 110 more convenient, which helps to improve the opening and closing efficiency of the bottom door mechanism 110, thereby improving the transportation efficiency of the funnel box 1000. Furthermore, since the opening and closing of the bottom door mechanism 110 are realized by the opening drive assembly 130 and the closing drive assembly 120 respectively, rather than by a set of drive assemblies, the movement speed of the bottom door mechanism 110 can be controlled more precisely to ensure the stability and reliability of the opening and closing actions. At the same time, it is also convenient to maintain and optimize the opening drive assembly 130 and the closing drive assembly 120 separately. Therefore, any problems can be quickly located and resolved, ensuring the efficient operation and safety of the funnel box bottom door unit 100, and improving the opening and closing efficiency and safety of the bottom door mechanism 110.

[0031] The structure of the bottom door mechanism 110 is varied and known to those skilled in the art, and is not limited in this disclosure.

[0032] In some embodiments, as shown in Figures 1 and 2, the bottom door mechanism 110 includes a main shaft assembly 111, a door panel assembly 112, and a connecting rod assembly 113. The main shaft assembly 111 is rotatably connected to the housing 200, and the closing drive assembly 120 and the opening transmission mechanism 132 are both connected to the main shaft assembly 111; the door panel assembly 112 is rotatably connected to the housing 200, and the door panel assembly 112 is used to cover the material leakage port; the connecting rod assembly 113 is hinged to the main shaft assembly 111 and the door panel assembly 112.

[0033] The upper end of the door panel assembly 112 is rotatably connected to the housing 200. A connecting rod assembly 113 is located between the door panel assembly 112 and the main shaft assembly 111. One end of the connecting rod assembly 113 is rotatably connected to the middle of the door panel assembly 112, and the other end is rotatably connected to the main shaft assembly 111. Both the closing drive assembly 120 and the opening drive assembly 130 are connected to the main shaft assembly 111 to drive it to move in opposite directions. If the closing drive assembly 120 drives the main shaft assembly 111 to rotate clockwise, then the opening drive assembly 130 drives the main shaft assembly 111 to rotate counterclockwise; conversely, if the closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, then the opening drive assembly 130 drives the main shaft assembly 111 to rotate clockwise. The main shaft assembly 111 rotates, driving the connecting rod assembly 113 to rotate, which in turn drives the door panel assembly 112 to rotate around the housing 200, thereby opening or closing the material leakage port. In some embodiments, the closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise. The opening drive assembly 130 drives the main shaft assembly 111 to rotate clockwise. When the main shaft assembly 111 rotates clockwise, the door panel assembly 112 opens the material leakage port; when the main shaft assembly 111 rotates counterclockwise, the door panel assembly 112 closes the material leakage port. For ease of description, this disclosure will use the example of the door panel assembly 112 opening the material leakage port when the main shaft assembly 111 rotates clockwise and the door panel assembly 112 closing the material leakage port when the main shaft assembly 111 rotates counterclockwise as an example.

[0034] In some embodiments, the door closing drive assembly 120 and the door opening drive mechanism 132 are respectively disposed at both ends of the main shaft assembly 111.

[0035] In some embodiments, along the axis of the main shaft assembly 111, the door closing drive assembly 120 is disposed at one end of the main shaft assembly 111, and the door opening drive assembly 130 is disposed at the other end of the main shaft assembly 111. The door closing drive assembly 120 and the door opening drive mechanism 132 are respectively disposed at both ends of the main shaft assembly 111 to help keep the door closing drive assembly 120 and the door opening drive mechanism 132 away from each other, thereby avoiding interference between the door closing drive assembly 120 and the door opening drive mechanism 132.

[0036] In some embodiments, the door panel assembly 112 includes a first door panel 1121 and a second door panel 1122 disposed opposite to each other. The upper ends of both the first door panel 1121 and the second door panel 1122 are rotatably connected to the housing 200. A main shaft assembly 111 and a connecting rod assembly 113 are located between the two door panels. The main shaft assembly 111 includes a main shaft 1111 and a first rotating arm 1112 and a second rotating arm 1113 fixedly disposed on the main shaft 1111. The first rotating arm 1112 is disposed on the side of the main shaft 1111 near the first door panel 1121. The second rotating arm 1113 is disposed on the side of the main shaft 1111 near the second door panel 1122. The connecting rod assembly 113 includes a first connecting rod 1131 and a second connecting rod 1132. The first connecting rod 1131 is disposed between the first door panel 1121 and the first rotating arm 1112. One end of the first connecting rod 1131 is rotatably connected to the end of the first rotating arm 1112 away from the first main shaft 1111, and the other end is rotatably connected to the middle region of the first door panel 1121. A second connecting rod 1132 is disposed between the second door panel 1122 and the second rotating arm 1113. One end of the second connecting rod 1132 is rotatably connected to the end of the second rotating arm 1113 away from the first main shaft 1111, and the other end is rotatably connected to the middle region of the second door panel 1122. Rotation of the main shaft 1111 can drive the first rotating arm 1112 and the second rotating arm 1113 to rotate, thereby driving the first connecting rod 1131 and the second connecting rod 1132 to rotate, thus causing the lower ends of the first door panel 1121 and the second door panel 1122 to move closer to or further away from each other. When the lower ends of the first door panel 1121 and the second door panel 1122 approach each other, the first door panel 1121 and the second door panel 1122 respectively open their corresponding material discharge ports; when the lower ends of the first door panel 1121 and the second door panel 1122 move away from each other, the first door panel 1121 and the second door panel 1122 respectively close their corresponding material discharge ports. In some embodiments, when the main shaft 1111 rotates clockwise, the lower ends of the first door panel 1121 and the second door panel 1122 approach each other; when the main shaft 1111 rotates counterclockwise, the lower ends of the first door panel 1121 and the second door panel 1122 move away from each other.

[0037] In some embodiments, the spindle assembly 111 includes two first rotating arms 1112 and two second rotating arms 1113. The two first rotating arms 1112 and the two second rotating arms 1113 are spaced apart along the axis of the spindle 1111. The connecting rod assembly 113 includes two first connecting rods 1131 and two second connecting rods 1132. The two first connecting rods 1131 and the two second connecting rods 1132 are spaced apart along a direction parallel to the spindle 1111.

[0038] As shown in Figure 3, in some embodiments, the door opening drive assembly 130 includes a door opening drive element 131 and a door opening transmission mechanism 132, with the door opening drive element 131 mounted on the housing 200; the door opening transmission mechanism 132 is mounted on the housing 200 and connected to the bottom door mechanism 110, and the door opening transmission mechanism 132 acts on the door opening drive element 131 and the bottom door mechanism 110; the door opening drive element 131 drives the door opening transmission mechanism 132 to move, so that the door opening transmission mechanism 132 drives the bottom door mechanism 110 to the open position.

[0039] Both the door opening drive element 131 and the door opening transmission mechanism 132 are mounted on the housing 200. The door opening transmission mechanism 132 is driven by the door opening drive element 131. The door opening drive element 131 drives the door opening transmission mechanism 132 to rotate clockwise, thereby causing the door panel assembly 112 to rotate around the housing 200, so that the door panel assembly 112 opens the material discharge port of the housing 200.

[0040] In some embodiments, the door opening mechanism 132 includes a lever assembly 1323, a first transmission member 1321, and a contact member 1322. The lever assembly 1323 is hinged to the housing 200 at its center. The contact member 1322 is fixedly connected to the bottom door mechanism 110. One end of the lever assembly 1323 is located above the contact member 1322. The first transmission member 1321 is connected to the other end of the lever assembly 1323. The door opening drive element 131 drives the first transmission member 1321 to move along the height direction, so that the lever assembly 1323 drives the contact member 1322 to move, thereby positioning the bottom door mechanism 110 in the open position.

[0041] The door opening drive element 131 drives the first transmission member 1321 to move along the height direction, and can drive the first transmission member 1321 to move upward or downward along the height direction. The contact member 1322 is fixedly connected to the main shaft 1111 of the main shaft assembly 111, and the middle part of the lever assembly 1323 is hinged to the housing 200; therefore, if the end of the lever assembly 1323 connected to the first transmission member 1321 is raised, the end above the contact member 1322 will be lowered; in this way, the lever assembly 1323 can press the contact member 1322 to press the contact member 1322 downward, thereby causing the main shaft assembly 111 to rotate clockwise by a certain angle, and then causing the main shaft assembly 111 to pass the dead point; after the main shaft assembly 111 passes the dead point, the material in the housing 200 will push the door panel assembly 112 to continue to rotate, so that the door panel assembly 112 is fully opened. In other words, when the lever assembly 1323 presses down on the contact member 1322, the main shaft assembly 111 rotates clockwise, and the door panel assembly 112 opens to a certain angle, allowing the door panel assembly 112 to fully open under the weight of the material. If the end of the lever assembly 1323 connected to the first transmission member 1321 lowers, the end above the contact member 1322 will rise. It is easy to understand that the contact member 1322 will return to its unpressed state under the action of the door closing drive assembly 120. In some embodiments, after the material has been completely lowered, the door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, which in turn causes the contact member 1322 to rotate counterclockwise, thus returning the contact member 1322 to its unpressed position. The lever assembly 1323 and the first transmission member 1321 can return to the state when the contact member 1322 is not pressed under the action of the door opening drive element 131, or they can return to the state when the contact member 1322 is not pressed under the action of the contact member 1322. If the lever assembly 1323 and the first transmission member 1321 are reset by the door opening drive element 131, the door opening drive element 131 drives the first transmission member 1321 to descend to the position before it was raised, thereby resetting the lever assembly 1323 and the first transmission member 1321. If the lever assembly 1323 and the first transmission member 1321 are reset by the contact member 1322, the contact member 1322 rotates counterclockwise by the door closing drive assembly 120, and then contacts the lever assembly 1323, causing the end of the lever assembly 1323 above the contact member 1322 to move upward, thereby resetting the lever assembly 1323 and the first transmission member 1321.

[0042] With this design, the lever assembly 1323 presses down on the contact member 1322, causing the contact member 1322 to drive the main shaft assembly 111 past the dead point, and the bottom door mechanism 110 can then be fully opened under the gravity of the material. Furthermore, the contact member 1322 and the lever assembly 1323 separate, overcoming the impact of the instantaneous rotational torque of the door panel assembly 112 at the moment of passing the dead point on the door opening drive element 131, the lever assembly 1323, and the first transmission component 1321. This helps to extend the service life of the door opening drive element 131, the lever assembly 1323, and the first transmission component 1321, thereby ensuring the continuous and stable operation of the door opening transmission mechanism 132. Furthermore, with this design, under the action of the lever assembly 1323, the door opening drive element 131 can apply a small force to the first transmission member 1321, which in turn allows the lever assembly 1323 to apply a large force to the contact member 1322. This enables the door opening drive element 131 to drive the contact member 1322 to rotate clockwise with a small force, thereby driving the main shaft assembly 111 to rotate clockwise. This helps to reduce the performance requirements of the door opening drive component 131 on the door opening drive component 130 and reduce the cost of the door opening drive component 130.

[0043] In some embodiments, during the process of the door closing drive assembly 120 driving the bottom door mechanism 110 to the shielded position, the lever assembly 1323, the first transmission member 1321 and the door opening drive element 131 are driven back to their initial positions by the contact member 1322.

[0044] The door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, thereby causing the contact member 1322 to rotate counterclockwise. When the contact member 1322 rotates counterclockwise to a certain angle, the contact member 1322 will contact the lever assembly 1323, causing the end of the lever assembly 1323 above the contact member 1322 to rise, thereby causing the end of the lever assembly 1323 connected to the first transmission member 1321 to fall. This causes the first transmission member 1321 and the door opening drive element 131 to fall, thereby resetting the lever assembly 1323, the first transmission member 1321, and the door opening drive element 131 to their initial positions. With this design, the lever assembly 1323, the first transmission component 1321, and the door opening drive element 131 are all reset by the drive of the contact component 1322, instead of being reset by controlling the movement of the door opening drive element 131. This reduces the requirements for the door opening drive element 131 and the complexity of its control logic. As a result, the door opening drive element 131 can drive the first transmission component 1321 to rise until the lever 13231 presses the contact component 1322 to rotate until the lever assembly 1323 passes the dead point, which helps to save the cost of the door opening transmission mechanism 132.

[0045] The door opening drive element 131 can be a hydraulic cylinder, a pneumatic cylinder, a lead screw nut, a scissor lift mechanism, etc., and is not limited in this disclosure.

[0046] In some embodiments, the door opening drive element 131 includes a drive element 1311 and an eccentric wheel 1312 mounted on the output end of the drive element 1311. A first transmission member 1321 is disposed above the eccentric wheel 1312.

[0047] The driving element 1311 can be a motor. An eccentric wheel 1312 is fixedly connected to the output shaft of the motor. The motor rotates to drive the eccentric wheel 1312 to rotate. A first transmission member 1321 is positioned above and in contact with the eccentric wheel 1312. Driven by the motor, when the eccentric wheel 1312 rotates counterclockwise, it can contact the first transmission member 1321, causing the first transmission member 1321 to move upwards. This causes the lever assembly 1323 to press down on the contact member 1322, thereby driving the main shaft assembly 111 to rotate past its dead center.

[0048] In some embodiments, the lever assembly 1323 includes a lever 13231 and a second transmission member 13232. The lever 13231 includes a first end 13231a, a hinged end 13231b, and a second end 13231c, which are spaced apart. The hinged end 13231b is disposed between the first end 13231a and the second end 13231c; the first end 13231a is connected to the first transmission member 1321; the hinged end 13231b is hinged to the housing 200; one end of the second transmission member 13232 is connected to the second end 13231c of the lever 13231, and the other end is located above the contact member 1322.

[0049] In other words, along the length of lever 13231, the first end 13231a, the hinged end 13231b, and the second end 13231c are arranged sequentially and at intervals. Lever 13231 is connected to the first transmission member 1321 via the first end 13231a, to the second transmission member 13232 via the second end 13231c, and rotatably connected to the housing 200 via the hinged end 13231b. With this design, the first transmission member 1321 moves upward, causing the first end 13231a to move upward, which in turn causes the second end 13231c to move downward, thereby causing the second transmission member 13232 to move downward, pressing the contact member 1322 located below it, and causing the contact member 1322 to rotate clockwise. With this design, when the closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, the contact member 1322 contacts the second transmission member 13232, causing the second transmission member 13232 to move upward, which in turn causes the second end 13231c of the lever 13231 to move upward, thereby causing the first end 13231a of the lever 13231 to move downward, which in turn causes the first transmission member 1321 to move downward; the first transmission member 1321 presses the eccentric wheel 1312, causing the eccentric wheel 1312 to drive the shaft of the opening drive element 131 to rotate counterclockwise, thereby resetting the lever assembly 1323, the first transmission member 1321 and the opening drive element 131.

[0050] In some embodiments, the distance from the first end 13231a to the hinge end 13231b is greater than the distance from the second end 13231c to the hinge end 13231b.

[0051] With this design, the drive element 1311 can use a smaller force to make the second transmission element 13232 drive the contact element 1322 to rotate, so that the main shaft assembly 111 passes the dead point. This helps to reduce the performance requirements of the drive element 1311 of the door opening drive assembly 130, thereby reducing the cost of the door opening drive assembly 130.

[0052] In some embodiments, the funnel box bottom door unit 100 includes two bottom door mechanisms 110. The door opening transmission mechanism 132 includes two contact members 1322. The two contact members 1322 are respectively mounted on the two bottom door mechanisms 110; the other end of the second transmission member 13232 is respectively located on the two contact members 1322.

[0053] One contact element 1322 is mounted on the main shaft 1111 of one bottom door mechanism 110, and the other contact element 1322 is mounted on the main shaft 1111 of the other bottom door mechanism 110; the second transmission element 13232 is located on both contact elements 1322. With this design, when the first transmission element 1321 rises under the drive of the eccentric wheel 1312, the second transmission element 13232 simultaneously presses down on the two contact elements 1322. The door opening transmission mechanism 132 drives the two bottom door mechanisms 110 to open synchronously, improving the opening efficiency of the bottom door mechanisms 110 and helping to increase the material feeding rate.

[0054] In some embodiments, the second transmission member 13232 includes a first connecting portion 13233, a second connecting portion 13234, and two third connecting portions 13235; the second connecting portion 13234 is connected to the second end 13231c of the lever 13231 and the middle part of the first connecting portion 13233; the two third connecting portions 13235 are respectively fixedly disposed at both ends of the first connecting portion 13233 and are respectively located above the two contact members 1322.

[0055] The first connecting portion 13233 is located below the lever 13231; the second connecting portion 13234 is disposed between the first connecting portion 13233 and the lever 13231; the upper end of the second connecting portion 13234 is connected to the second end 13231c of the lever 13231, and the lower end is connected to the first connecting portion 13233. Two third connecting portions 13235 are respectively connected to one end of the first connecting portion 13233 and the other end of the first connecting portion 13233; one third connecting portion 13235 is located above one of the contact members 1322, and the other third connecting portion 13235 is located above the other contact member 1322. In some embodiments, the upper end of the third connecting portion 13235 is fixedly connected to the first connecting portion 13233, and the lower end of the third connecting portion 13235 is located above the contact member 1322.

[0056] It should be noted that the two main shafts 1111 of the two bottom door mechanisms 110 are arranged in parallel. In some embodiments, the lever 13231 is arranged perpendicular to the main shaft 1111 of the bottom door mechanism 110, and the first connecting part 13233 and the lever 13231 are arranged in parallel.

With this design, the first transmission member 1321 can rotate about the first end 13231a of the lever 13231; when the lever 13231 rotates about the hinge end 13231b, the first end 13231a of the lever 13231 will also rotate; with this design, the upper end of the first transmission member 1321 can follow the rotation of the first end 13231a of the lever 13231, and the lower end of the first transmission member 1321 can be located on the eccentric wheel 1312, so that the lower end of the first transmission member 1321 is always above the eccentric wheel 1312, thereby ensuring the stability of the first transmission member 1321. With this design, the second transmission component 13232 can rotate around the second end 13231c of the lever 13231, and when the lever 13231 rotates around the hinge end 13231b, the second end 13231c of the lever 13231 will also rotate. With this design, the upper end of the second transmission component 13232 can rotate with the second end 13231c of the lever 13231, and the lower end of the second transmission component 13232, that is, the lower end of the third connecting part 13235, can always be located on the contact member 1322. The two third connecting parts 13235 can press the two contact members 1322 at the same time, thereby ensuring the stability of the second transmission component 13232 and ensuring that the two bottom door mechanisms 110 open synchronously.

[0059] In some embodiments, the door closing drive assembly 120 includes a door closing drive element 121 and a door closing transmission mechanism 122. The door closing drive element 121 is mounted on the housing 200. The door closing transmission mechanism 122 is driven by the door closing drive element 121 and is connected to the bottom door mechanism 110. Under the action of the door closing drive element 121, the door closing transmission mechanism 122 drives the bottom door mechanism 110 to the shielded position.

[0060] The door closing drive element 121 drives the door closing transmission mechanism 122 to move. The door closing transmission mechanism 122 is connected to the main shaft assembly 111 of the bottom door mechanism 110. The door closing transmission mechanism 122 drives the main shaft assembly 111 to rotate counterclockwise, thereby causing the door panel assembly 112 of the bottom door mechanism 110 to rotate and causing the door panel assembly 112 to cover the material leakage port of the box 200.

[0061] In some embodiments, the door closing transmission mechanism 122 includes a first gear 1221, a second gear 1222, and a first transmission chain 1223; the first gear 1221 is mounted on the output end of the door closing drive element 121 and is driven by the door closing drive element 121; the second gear 1222 is mounted on the bottom door mechanism 110; and the first transmission chain 1223 is connected to the first gear 1221 and the second gear 1222.

[0062] The first gear 1221 is fixedly connected to the output end of the door closing drive element 121, and the door closing drive element 121 drives the first gear 1221 to rotate. The first transmission chain 1223 is sleeved on the outside of the first gear 1221 and the second gear 1222, and meshes with both the first gear 1221 and the second gear 1222. The second gear 1222 is fixedly connected to the main shaft 1111 of the bottom door mechanism 110. With this design, the door closing drive element 121 drives the first gear 1221 to rotate, thereby driving the first transmission chain 1223 to rotate, which in turn drives the second gear 1222 to rotate counterclockwise, causing the main shaft 1111 of the bottom door mechanism 110 to rotate counterclockwise, thereby causing the door panel assembly 112 of the bottom door mechanism 110 to rotate, and causing the door panel assembly 112 to cover the material leakage port of the box 200.

[0063] In some embodiments, the funnel box bottom door unit 100 includes two bottom door mechanisms 110. A second gear 1222 is mounted on one of the bottom door mechanisms 110. The closing transmission mechanism 122 also includes a third gear 1224, a fourth gear 1225, and a second transmission chain 1226; the third gear 1224 is mounted on the bottom door mechanism 110 where the second gear 1222 is located; the fourth gear 1225 is mounted on the other bottom door mechanism 110; and the second transmission chain 1226 is connected to the third gear 1224 and the fourth gear 1225.

[0064] The third gear 1224 is fixedly connected to the main shaft 1111 where the second gear 1222 is located; the fourth gear 1225 is fixedly connected to another main shaft 1111; the second transmission chain 1226 is sleeved on the third gear 1224 and the fourth gear 1225 and meshes with the third gear 1224 and the fourth gear 1225. With this design, the door closing drive element 121 drives the first gear 1221 to rotate counterclockwise, thereby driving the first transmission chain 1223 and the second transmission chain 1226 to rotate counterclockwise synchronously, causing the second gear 1222 and the fourth gear 1225 to rotate counterclockwise, causing the two main shafts 1111 to rotate counterclockwise, and causing the door panels of the two bottom door mechanisms 110 to rotate synchronously to block the leakage port, thereby improving the closing efficiency of the bottom door mechanism 110. It should be noted that when the main shaft 1111 rotates clockwise, the main shaft 1111 drives the second gear 1222 and the fourth gear 1225 to rotate clockwise, thereby driving the first transmission chain 1223 and the second transmission chain 1226 to rotate clockwise synchronously, so that the output end of the door closing drive element 121 rotates clockwise.

[0065] In some embodiments, the door closing drive element 121 is a motor.

[0066] It should be noted that the two bottom door mechanisms 110 are spaced apart. In some embodiments, along the direction in which the two bottom door mechanisms 110 are spaced apart, the first gear 1221 and the second gear 1222 are spaced apart, and the third gear 1224 and the fourth gear 1225 are also spaced apart.

[0067] Based on the same inventive concept, this disclosure also provides a funnel box 1000, including a box body 200 and the aforementioned funnel box bottom door unit 100; the box body 200 has a material outlet; the bottom door mechanism 110, the closing drive assembly 120, the opening drive element 131 and the opening transmission mechanism 132 of the funnel box bottom door unit 100 are all installed on the box body 200.

[0068] In some embodiments, the main shaft 1111 of the bottom door mechanism 110 is rotatably connected to the box body 200, and the upper end of the door panel assembly 112 is rotatably connected to the box body 200. Since the funnel box 1000 includes the aforementioned funnel box bottom door unit 100, it naturally possesses all the beneficial effects of the funnel box bottom door unit 100, which will not be elaborated here.

[0069] The technical solutions according to some embodiments of this disclosure have at least the following beneficial effects. The funnel box bottom door unit has a closing drive assembly for controlling the closing of the bottom door mechanism and an opening drive assembly for controlling the opening of the bottom door mechanism. Therefore, the funnel box having the bottom door unit according to some embodiments of this disclosure can realize the opening and closing of the bottom door mechanism through its own structure, without needing to cooperate with ground facilities. This makes opening and closing the bottom door mechanism more convenient, helping to improve the opening and closing efficiency of the bottom door mechanism, thereby improving the transportation efficiency of the funnel box. Furthermore, the opening and closing of the bottom door mechanism are realized separately by the opening drive assembly and the closing drive assembly, rather than by a set of drive assemblies. This design allows for more precise control of the movement speed of the bottom door mechanism, ensuring the stability and reliability of the opening and closing actions. It also facilitates the separate maintenance and optimization of the opening and closing drive assemblies. Problems can be quickly located and resolved, thus ensuring the efficient operation and safety performance of the funnel box bottom door unit, and improving the opening and closing efficiency and safety of the bottom door mechanism.
