[0060] In the related art, hopper cars have a technical problem of using a touch-type bottom door opening and closing mechanism, which is inconvenient to use. The embodiments of the present application provide a hopper box bottom door unit and a hopper box, which can at least to some extent solve the technical problem of using a touch-type bottom door opening and closing mechanism in hopper cars, which is inconvenient to use.

[0061] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0062] like Figures 1 to 8 As shown, the hopper box bottom door unit 100 is installed on the box body 200 of the hopper box 1000. The box body 200 of the hopper box 1000 is provided with a material leakage opening. The hopper box bottom door unit 100 includes a bottom door mechanism 110, a door closing drive assembly 120, and a door opening drive assembly 130. The bottom door mechanism 110 is installed on the box body 200 and has a shielding position for shielding the material leakage opening and an open position for opening the material leakage opening; the door 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 shielding position; the door 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.

[0063] The bottom of the box body 200 of the hopper box 1000 is provided with a material leakage opening through which the material in the hopper box 1000 leaks out. The bottom door mechanism 110 is installed on the box body 200, and the bottom door mechanism 110 can shield the material leakage opening so that the material leakage opening is in a closed state, and at this time, the material in the hopper box 1000 cannot leak out through the material leakage opening. The bottom door mechanism 110 can also not shield the material leakage opening so that the material leakage opening is in an open state, and at this time, the material in the hopper box 1000 can leak out through the material leakage opening.

[0064] The door closing driving assembly 120 is installed on the box body 200, and the door closing driving assembly 120 is connected with the bottom door mechanism 110 and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 can be located at the shielding position. The door opening driving assembly 130 is installed on the box body 200, and the door opening driving assembly 130 is connected with the bottom door mechanism 110 and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 can be located at the opening position.

[0065] In this way, the hopper box bottom door unit 100 has the door closing driving assembly 120 for controlling the bottom door mechanism 110 to close and the door opening driving assembly 130 for controlling the bottom door mechanism 110 to open, and the hopper box 1000 with the hopper box bottom door unit 100 can realize the opening and closing of the bottom door mechanism 110 by the structure itself, and does not need to realize the opening and closing of the bottom door mechanism 110 by cooperating with the ground facilities. The opening and closing of the bottom door mechanism 110 is more convenient, which helps to improve the opening efficiency and closing efficiency of the bottom door mechanism 110, thereby improving the transportation efficiency of the hopper box 1000. Moreover, the opening and closing of the bottom door mechanism 110 is realized by the door opening driving assembly 130 and the door closing driving assembly 120 respectively, rather than by a group of driving assemblies. In this way, the movement speed of the bottom door mechanism 110 can be more accurately controlled, the stability and reliability of the opening and closing actions are ensured, and the door opening driving assembly 130 and the door closing driving assembly 120 can be maintained and optimized respectively. Once a problem occurs, the problem can be quickly located and solved, which ensures the efficient operation and safety performance of the hopper box bottom door unit 100 and improves the opening and closing efficiency and safety of the bottom door mechanism 110.

[0066] The specific structure of the bottom door mechanism 110 is various and known to those skilled in the art, and is not limited in the present application.

[0067] In some embodiments, as shown in FIG. 1, the hopper box bottom door unit 100 further comprises a door opening and closing driving assembly 140, and the door opening and closing driving assembly 140 is connected with the bottom door mechanism 110 and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 can be located at the shielding position or the opening position. Figure 1 and Figure 2As shown, the bottom door mechanism 110 includes a main shaft component 111, a door plate component 112, and a connecting rod component 113. The main shaft component 111 is rotationally connected to the box body 200, and the door closing driving assembly 120 and the door opening transmission mechanism 132 are both connected to the main shaft component 111. The door plate component 112 is rotationally connected to the box body 200, and the door plate component 112 is used to shield the material leakage hole. The connecting rod component 113 is hingedly connected to the main shaft component 111 and the door plate component 112.

[0068] The upper end of the door plate component 112 is rotationally connected to the box body 200, the connecting rod component 113 is located between the door plate component 112 and the main shaft component 111, one end of the connecting rod component 113 is rotationally connected to the middle of the door plate component 112, and the other end is rotationally connected to the main shaft component 111. The door closing driving assembly 120 and the door opening driving assembly 130 are both connected to the main shaft component 111 and are used to drive the main shaft component 111 to move in opposite directions. If the door closing driving assembly 120 drives the main shaft component 111 to rotate clockwise, the door opening driving assembly 130 drives the main shaft component 111 to rotate counterclockwise; if the door closing driving assembly 120 drives the main shaft component 111 to rotate counterclockwise, the door opening driving assembly 130 drives the main shaft component 111 to rotate clockwise. The main shaft component 111 rotates, driving the connecting rod component 113 to rotate, and driving the door plate component 112 to rotate around the box body 200, so as to open or close the material leakage hole. In some embodiments, the door closing driving assembly 120 drives the main shaft component 111 to rotate counterclockwise, the door opening driving assembly 130 drives the main shaft component 111 to rotate clockwise, the door plate component 112 opens the material leakage hole when the main shaft component 111 rotates clockwise, and the door plate component 112 closes the material leakage hole when the main shaft component 111 rotates counterclockwise. In order to facilitate the introduction of the present application, the following text of the present application is introduced by taking the door plate component 112 opening the material leakage hole when the main shaft component 111 rotates clockwise and the door plate component 112 closing the material leakage hole when the main shaft component 111 rotates counterclockwise as an example.

[0069] In some embodiments, the door closing driving assembly 120 and the door opening transmission mechanism 132 are respectively arranged at the two ends of the main shaft component 111.

[0070] Specifically, along the axis of the main shaft component 111, the door closing driving assembly 120 is arranged at one end of the main shaft component 111, and the door opening driving assembly 130 is arranged at the other end of the main shaft component 111. Arranging the door closing driving assembly 120 and the door opening transmission mechanism 132 at the two ends of the main shaft component 111 helps to keep the door closing driving assembly 120 and the door opening transmission mechanism 132 away from each other, avoiding interference between the door closing driving assembly 120 and the door opening transmission mechanism 132.

[0071] In some embodiments, the door plate assembly 112 includes a first door plate 1121 and a second door plate 1122 arranged oppositely, and upper ends of the first door plate 1121 and the second door plate 1122 are rotationally connected to the box body 200. The main shaft assembly 111 and the connecting rod assembly 113 are located between the two door plates. The main shaft assembly 111 includes a main shaft 1111, a first rotating arm 1112 and a second rotating arm 1113 fixedly arranged on the main shaft 1111. The first rotating arm 1112 is arranged on the side of the main shaft 1111 close to the first door plate 1121, and the second rotating arm 1113 is arranged on the side of the main shaft 1111 close to the second door plate 1122. The connecting rod assembly 113 includes a first connecting rod 1131 and a second connecting rod 1132. The first connecting rod 1131 is arranged between the first door plate 1121 and the first rotating arm 1112, one end of the first connecting rod 1131 is rotationally connected to the end of the first rotating arm 1112 away from the first main shaft 1111, and the other end is rotationally connected to the middle region of the first door plate 1121. The second connecting rod 1132 is arranged between the second door plate 1122 and the second rotating arm 1113, one end of the second connecting rod 1132 is rotationally connected to the end of the second rotating arm 1113 away from the first main shaft 1111, and the other end is rotationally connected to the middle region of the second door plate 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, and further causing the lower ends of the first door plate 1121 and the second door plate 1122 to approach or move away from each other. When the lower ends of the first door plate 1121 and the second door plate 1122 approach each other, the first door plate 1121 and the second door plate 1122 open the corresponding material leakage openings respectively; when the lower ends of the first door plate 1121 and the second door plate 1122 move away from each other, the first door plate 1121 and the second door plate 1122 close the corresponding material leakage openings respectively. In some embodiments, when the main shaft 1111 rotates clockwise, the lower ends of the first door plate 1121 and the second door plate 1122 approach each other, and when the main shaft 1111 rotates counterclockwise, the lower ends of the first door plate 1121 and the second door plate 1122 move away from each other.

[0072] In some embodiments, the main shaft assembly 111 includes two first rotating arms 1112 and two second rotating arms 1113, and the two first rotating arms 1112 and the two second rotating arms 1113 are arranged at intervals along the axis of the main shaft 1111. The connecting rod assembly 113 includes two first connecting rods 1131 and two second connecting rods 1132, and the two first connecting rods 1131 and the two second connecting rods 1132 are arranged at intervals in a direction parallel to the main shaft 1111.

[0073] As Figure 3As shown, in some embodiments, the door opening driving assembly 130 comprises a door opening driving element 131 and a door opening transmission mechanism 132. The door opening driving element 131 is installed on the box body 200. The door opening transmission mechanism 132 is installed on the box body 200 and connected with the bottom door mechanism 110. The door opening transmission mechanism 132 acts on the door opening driving element 131 and the bottom door mechanism 110. The door opening driving 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 be located at the open position.

[0074] The door opening driving element 131 and the door opening transmission mechanism 132 are both installed on the box body 200. The door opening transmission mechanism 132 is driven by the door opening driving element 131. The door opening driving element 131 drives the door opening transmission mechanism 132 to move, so that the main shaft assembly 111 of the bottom door mechanism 110 is driven to rotate clockwise, thereby driving the door plate assembly 112 to rotate around the box body 200, so that the door plate assembly 112 opens the material leakage opening of the box body 200.

[0075] In some embodiments, the door opening transmission mechanism 132 comprises a lever assembly 1323, a first transmission member 1321 and a contact member 1322. The middle part of the lever assembly 1323 is hinged to the box body 200. 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 driving 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, so that the bottom door mechanism 110 is located at the open position.

[0076] The door opening driving 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 hingedly connected to the box body 200. Therefore, if the end of the lever assembly 1323 connected to the first transmission member 1321 is raised, the end located above the contact member 1322 will be lowered, so that the lever assembly 1323 can press the contact member 1322 downward, thereby making the main shaft assembly 111 rotate clockwise by a certain angle, so that the main shaft assembly 111 passes through the dead point. After the main shaft assembly 111 passes through the dead point, the material in the box body 200 will push the door plate assembly 112 to continue to rotate, so that the door plate assembly 112 is completely opened. That is, after the lever assembly 1323 presses the contact member 1322 downward, and the door plate assembly 112 is opened by a certain angle, the door plate assembly 112 will be completely opened under the action of the gravity of the material. If the end of the lever assembly 1323 connected to the first transmission member 1321 is lowered, the end located above the contact member 1322 will be raised. It is easy to understand that the contact member 1322 will be brought back to the state before being pressed by the door closing driving assembly 120. Specifically, after the material is completely lowered, the door closing driving assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, so that the contact member 1322 rotates counterclockwise, and the contact member 1322 returns to the position before being pressed. The lever assembly 1323 and the first transmission member 1321 can return to the state before pressing the contact member 1322 under the action of the door opening driving element 131, or can return to the state before pressing the contact member 1322 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 driving element 131, the door opening driving element 131 drives the first transmission member 1321 to descend to the position before being raised, so that the lever assembly 1323 and the first transmission member 1321 are reset. If the lever assembly 1323 and the first transmission member 1321 are reset by the contact member 1322, after the contact member 1322 rotates counterclockwise by a certain angle under the action of the door closing driving assembly 120, the contact member 1322 will contact the lever assembly 1323, and drive the end of the lever assembly 1323 located above the contact member 1322 to move upward, so that the lever assembly 1323 and the first transmission member 1321 are reset.

[0077] In this way, the lever assembly 1323 presses the contact piece 1322 downward, so that the contact piece 1322 drives the main shaft assembly 111 to pass the dead point, and then the bottom door mechanism 110 can be completely opened under the gravity of the material, and the contact piece 1322 and the lever assembly 1323 are separated, thereby overcoming the impact of the instantaneous rotation torque of the door plate assembly 112 on the opening door driving element 131, the lever assembly 1323 and the first transmission element 1321 when passing the dead point, helping to prolong the service life of the opening door driving element 131, the lever assembly 1323 and the first transmission element 1321, and ensure the continuous and stable operation of the opening door transmission mechanism 132. In this way, under the action of the lever assembly 1323, the opening door driving element 131 can apply a smaller force to the first transmission element 1321, so that the lever assembly 1323 can apply a larger force to the contact piece 1322, and the opening door driving element 131 can drive the contact piece 1322 to rotate clockwise, thereby driving the main shaft assembly 111 to rotate clockwise, which helps to reduce the requirements for the performance of the opening door driving element 131 of the opening door driving assembly 130, and reduce the cost of the opening door driving assembly 130.

[0078] In some embodiments, during the process that the closing door driving assembly 120 drives the bottom door mechanism 110 to move to the shielding position, the lever assembly 1323, the first transmission element 1321 and the opening door driving element 131 are driven by the contact piece 1322 to return to the initial position.

[0079] The closing door driving assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, thereby driving the contact piece 1322 to rotate counterclockwise, and when the contact piece 1322 rotates counterclockwise to a certain angle, the contact piece 1322 will contact the lever assembly 1323, so that the end of the lever assembly 1323 above the contact piece 1322 rises, thereby causing the end of the lever assembly 1323 connected with the first transmission element 1321 to descend, so that the first transmission element 1321 and the opening door driving element 131 descend, thereby causing the lever assembly 1323, the first transmission element 1321 and the opening door driving element 131 to reset to the initial position. In this way, the lever assembly 1323, the first transmission element 1321 and the opening door driving element 131 are reset by the contact piece 1322, without the need to reset by controlling the movement of the opening door driving element 131, thereby reducing the requirements for the opening door driving element 131, reducing the complexity of the control logic of the opening door driving element 131, and enabling the opening door driving element 131 to drive the first transmission element 1321 to rise to the lever 13231 to press the contact piece 1322 to rotate to the dead point of the lever assembly 1323, thereby helping to save the cost of the opening door transmission mechanism 132.

[0080] The opening door driving element 131 can be an oil cylinder, an air cylinder, a screw nut, a scissor arm lifting mechanism, etc., which is not limited in the present application.

[0081] In some embodiments, the door opening driving element 131 comprises a driving rotating element 1311 and an eccentric wheel 1312 mounted on the output end of the driving rotating element 1311, and the first transmission element 1321 is arranged above the eccentric wheel 1312.

[0082] The driving rotating element 1311 can be a motor, and the eccentric wheel 1312 is fixedly connected to the output shaft of the motor. When the motor rotates, the eccentric wheel 1312 rotates. The first transmission element 1321 is arranged above the eccentric wheel 1312 and in contact with the eccentric wheel 1312. Under the driving of the motor, when the eccentric wheel 1312 rotates counterclockwise, the eccentric wheel 1312 can contact the first transmission element 1321 and drive the first transmission element 1321 to move upward, so as to drive the lever assembly 1323 to press the contact element 1322 and drive the main shaft assembly 111 to rotate through the dead point.

[0083] In some embodiments, the lever assembly 1323 comprises a lever 13231 and a second transmission element 13232. The lever 13231 has a first end 13231a, a hinged end 13231b and a second end 13231c arranged at intervals. The hinged end 13231b is arranged between the first end 13231a and the second end 13231c. The first end 13231a is connected to the first transmission element 1321, and the hinged end 13231b is hinged to the box body 200. One end of the second transmission element 13232 is connected to the second end 13231c of the lever 13231, and the other end is arranged above the contact element 1322.

[0084] That is, the first end 13231a, the hinged end 13231b and the second end 13231c are sequentially arranged and spaced along the length direction of the lever 13231. The lever 13231 is connected to the first transmission member 1321 through the first end 13231a, connected to the second transmission member 13232 through the second end 13231c, and rotationally connected to the box body 200 through the hinged end 13231b. In this way, when the first transmission member 1321 moves upward, the first end 13231a moves upward, the second end 13231c moves downward, and the second transmission member 13232 moves downward, the second transmission member 13232 presses the contact member 1322 below it, and the contact member 1322 rotates clockwise. In this way, when the door opening driving assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, the contact member 1322 contacts the second transmission member 13232, drives the second transmission member 13232 to move upward, the second end 13231c of the lever 13231 moves upward, and the first end 13231a of the lever 13231 moves downward, the first transmission member 1321 moves downward, the first transmission member 1321 presses the eccentric wheel 1312, the eccentric wheel 1312 drives the rotation shaft of the door opening driving element 131 to rotate counterclockwise, and the lever assembly 1323, the first transmission member 1321 and the door opening driving element 131 are reset.

[0085] In some embodiments, the distance from the first end 13231a to the hinged end 13231b is greater than the distance from the second end 13231c to the hinged end 13231b.

[0086] In this way, the second transmission member 13232 can drive the contact member 1322 to rotate with smaller force of the driving element 1311, the main shaft assembly 111 can pass the dead point, and the performance requirement of the door opening driving assembly 130 on the driving element 1311 is reduced, and the cost of the door opening driving assembly 130 is reduced.

[0087] 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 installed on the two bottom door mechanisms 110, and the other end of the second transmission member 13232 is respectively located on the two contact members 1322.

[0088] One of the contact members 1322 is installed on the main shaft 1111 of one of the bottom door mechanisms 110, and the other contact member 1322 is installed on the main shaft 1111 of the other bottom door mechanism 110. The second transmission member 13232 is located on both contact members 1322 at the same time. In this way, when the first transmission member 1321 is driven to rise by the eccentric wheel 1312, the second transmission member 13232 is simultaneously pressed downward on both contact members 1322. The door opening transmission mechanism 132 drives the two bottom door mechanisms 110 to open synchronously, thereby improving the opening efficiency of the bottom door mechanisms 110 and helping to improve the material dropping rate.

[0089] 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 of the first connecting portion 13233. The two third connecting portions 13235 are respectively fixedly arranged at the two ends of the first connecting portion 13233 and are respectively located above the two contact members 1322.

[0090] The first connecting portion 13233 is located below the lever 13231, and the second connecting portion 13234 is arranged 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. The 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 of the third connecting portions 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. Specifically, 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.

[0091] 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 perpendicularly to the main shaft 1111 of the bottom door mechanism 110, and the first connecting portion 13233 and the lever 13231 are arranged in parallel.

[0092] In some embodiments, the second connecting portion 13234 is connected to the middle of the first connecting portion 13233.

[0093] In some embodiments, the second connecting part 13234 is rotationally connected with the second end 13231c of the lever 13231 around an axis parallel to the main shaft 1111, and the upper end of the first transmission member 1321 is rotationally connected with the first end 13231a of the lever 13231 around an axis parallel to the main shaft 1111. In this way, the first transmission member 1321 can rotate around the first end 13231a of the lever 13231, and when the lever 13231 rotates around the hinged end 13231b, the first end 13231a of the lever 13231 also rotates. In this way, the upper end of the first transmission member 1321 can rotate with the first end 13231a of the lever 13231, and the lower end of the first transmission member 1321 can be located above the eccentric wheel 1312, which helps to ensure that the lower end of the first transmission member 1321 is always located above the eccentric wheel 1312, thereby ensuring the stability of the first transmission member 1321. In this way, the second transmission member 13232 can rotate around the second end 13231c of the lever 13231, and when the lever 13231 rotates around the hinged end 13231b, the second end 13231c of the lever 13231 also rotates. In this way, the upper end of the second transmission member 13232 can rotate with the second end 13231c of the lever 13231, and the lower end of the second transmission member 13232, i.e., the lower end of the third connecting part 13235, can always be located on the contact member 1322, and the two third connecting parts 13235 can simultaneously press the two contact members 1322, thereby ensuring the stability of the second transmission member 13232 and ensuring that the two bottom door mechanisms 110 are opened synchronously.

[0094] In some embodiments, the door closing driving assembly 120 comprises a door closing driving element 121 and a door closing transmission mechanism 122. The door closing driving element 121 is installed on the box body 200. The door closing transmission mechanism 122 is driven by the door closing driving element 121 and connected with the bottom door mechanism 110. Under the action of the door closing driving element 121, the door closing transmission mechanism 122 drives the bottom door mechanism 110 to the shielding position.

[0095] The door closing driving element 121 drives the door closing transmission mechanism 122 to move. The door closing transmission mechanism 122 is connected with the main shaft group 111 of the bottom door mechanism 110. The door closing transmission mechanism 122 drives the main shaft group 111 to rotate counterclockwise, thereby driving the door plate group 112 of the bottom door mechanism 110 to rotate and shielding the material leakage opening of the box body 200.

[0096] In some embodiments, the door closing transmission mechanism 122 comprises a first gear 1221, a second gear 1222, and a first transmission chain 1223. The first gear 1221 is installed on the output end of the door closing driving element 121 and is driven to rotate by the door closing driving element 121. The second gear 1222 is installed on the bottom door mechanism 110. The first transmission chain 1223 is connected with the first gear 1221 and the second gear 1222.

[0097] The first gear 1221 is fixedly connected to the output end of the door closing driving element 121, and the door closing driving element 121 drives the first gear 1221 to rotate; the first transmission chain 1223 is sleeved outside the first gear 1221 and the second gear 1222 and is engaged with the first gear 1221 and the second gear 1222, and the second gear 1222 is fixedly connected to the main shaft 1111 of the bottom door mechanism 110. After such design, the door closing driving element 121 drives the first gear 1221 to rotate, drives the first transmission chain 1223 to rotate, and thus drives the second gear 1222 to rotate counterclockwise, so that the main shaft 1111 of the bottom door mechanism 110 rotates counterclockwise, thereby driving the door plate assembly 112 of the bottom door mechanism 110 to rotate, so that the door plate assembly 112 shields the material leakage opening of the box body 200.

[0098] In some embodiments, the funnel box bottom door unit 100 includes two bottom door mechanisms 110, the second gear 1222 is installed on one of the bottom door mechanisms 110, and the door closing transmission mechanism 122 further includes a third gear 1224, a fourth gear 1225 and a second transmission chain 1226, the third gear 1224 is installed on the bottom door mechanism 110 where the second gear 1222 is located; the fourth gear 1225 is installed 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.

[0099] 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 the other main shaft 1111, and the second transmission chain 1226 is sleeved outside the third gear 1224 and the fourth gear 1225 and is engaged with the third gear 1224 and the fourth gear 1225. After such design, the door closing driving element 121 drives the first gear 1221 to rotate counterclockwise, drives the first transmission chain 1223 and the second transmission chain 1226 to rotate counterclockwise synchronously, thereby driving the second gear 1222 and the fourth gear 1225 to rotate counterclockwise, driving the two main shafts 1111 to rotate counterclockwise, and driving the door plate assemblies 112 of the two bottom door mechanisms 110 to rotate synchronously to shield the material leakage opening, 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, and the output end of the door closing driving element 121 rotates clockwise.

[0100] In some embodiments, the door closing driving element 121 is a motor.

[0101] 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.

[0103] Specifically, 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 hopper box 1000 includes the above-mentioned hopper box bottom door unit 100, it naturally has all the beneficial effects of the hopper box bottom door unit 100, which will not be described in detail here.
