Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] 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 claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0027] Figure 1-Figure 8 A specific embodiment of the present invention is a fertilizer transport sealing device, such as Figure 1 , Figure 2 , Figure 3 As shown, the sealed box body 1 is hinged with a box door 2 on the side, and at least two sealed chambers 101 are opened inside. A plurality of mutually transmission-connected drive rods 5 are inserted in the sealed box body 1. The drive rods 5 control the spring pressure plates 3 arranged at the top and upper part of the sealed chamber 101 to move up and down. One of the drive rods 5 is driven to rotate by the rotation of the box door 2, and a storage box 4 containing fertilizer is clamped between the two spring pressure plates 3. Tilted guide plates 102 are fixed on both sides of the opening of the sealed chamber 101 of the sealed box body 1, and the forward projection of the guide plates 102 covers the drive rods 5. The guide plates 102 are provided to prevent the storage box 4 from touching the drive rods 5 when entering and exiting. The drive rods 5 are rotatably inserted at the four corners of the sealed box body 1, and the drive rod 5 on the lower left side is transmission-connected to the drive rod 5 on the upper left side through the synchronous belt 504, the drive rod 5 on the upper left side is transmission-connected to the drive rod 5 on the upper right side, and the drive rod 5 on the upper right side is transmission-connected to the drive rod 5 on the lower right side.

[0028] like Figure 1 , Figure 4 , Figure 8As shown, the driving rod 5 is divided into two upper and lower thread directions at a position located inside one of the sealed bins 101, the rotation direction of the first thread 501 at the top is opposite to the rotation direction of the second thread 502 at the bottom, and a pressing nut 503 is connected to the threads with different rotation directions, and the pressing nut 503 is a structure with an inner circle and an outer square, and one side thereof is close to the inner wall of the sealed box body 1. A spring pressure plate 3 is provided on one side of the pressing nut 503, and the spring pressure plate 3 includes a pressure plate connected to the driving rod 5 by sliding up and down, and a spring 301 is connected between the pressure plate and the bottom or top of the sealed bin 101, and the pressing nut 503 is driven to move up and down by rotating the driving rod 5, thereby driving the pressure plate to move up and down. A rubber layer is attached to the surface of the pressure plate, and the storage box 4 is a rectangular box structure with an upper opening, and the rubber layer plays a sealing role when the storage box 4 is clamped.

[0029] like Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the top of the driving rod 5 on the lower left side is fixedly connected to one end of the telescopic pull rod 6, and the other end of the telescopic pull rod 6 is rotatably connected to the hinge column 201 on the door 2. When the door 2 is in a closed state, the two pressing nuts 503 in the same sealed chamber 101 are close to each other, and the upper and lower spring pressure plates 3 clamp the sealed storage box 4. When the door 2 is opened and turned to the maximum opening, the telescopic pull rod 6 drives the driving rod 5 to rotate, and the driving rod 5 drives the pressing nuts 503 thereon to move up and down, pressing the spring pressure plate 3 to the inner wall of the sealed chamber 101, and the spring pressure plate 3 releases the clamping of the storage box 4, and the storage box 4 can be taken and placed. The bottom of the storage box 4 is provided with a groove, which is convenient for forklifts to pick up and place.

[0030] The specific practical method of this embodiment is as follows:

[0031] In the empty box state, the box door 2 is opened and the box door 2 is at the maximum opening. During the process of opening the box door 2, the telescopic pull rod 6 drives the driving rod 5 on the lower left side to rotate, and drives all the driving rods 5 to rotate through the synchronous belt 504. The pressing nut 503 on the driving rod 5 is limited by the inner wall of the sealed chamber 101 on one side, so that the pressing nut 503 will not rotate relative to the sealed chamber 101, but moves up and down, pressing the upper spring pressure plate 3 upward and pressing the lower spring pressure plate 3 downward. The space left between the two spring pressure plates 3 is convenient for feeding the storage box 4 containing fertilizer. During the feeding process, due to the presence of the guide plate 102, the storage box 4 will not bump against the driving rod 5, and can be quickly placed. Finally, the box door 2 is closed to drive the driving rod 5 to rotate in the opposite direction, so that the pressing nut 503 moves in the opposite direction, and the pressing of the spring pressure plate 3 is released. The spring pressure plate 3 will clamp the storage box 4 under the action of elastic force to complete the sealing.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
