[0027] like Figure 1-6 As shown, a vegetable storage and transportation device of the present invention comprises a truck compartment 1 and a plurality of storage frames 11, a compartment door 101 is arranged at the front end of the truck compartment 1, two bearing platforms 12 are fixed on the left and right sides of the truck compartment 1, a slide groove 13 is opened at the upper end of the truck compartment 1, a screw rod 14 is rotatably installed in the slide groove 13, a motor is installed in the truck compartment 1, the output shaft of the motor is transmission-connected with the screw rod 14, a slide plate 15 is slidingly arranged in the slide groove 13, the slide plate 15 is threadedly connected with the screw rod 14, the slide plate 15 is connected with a box body 16 sliding in the slide groove 13, the lower side of the box body 16 is opened, an electric scissor-type telescopic frame 17 is arranged in the box body 16, a movable plate 18 is connected to the lower side of the electric scissor-type telescopic frame 17, an electromagnet 181 is installed on the lower side of the movable plate 18, and an iron bar matching the electromagnet 181 is arranged on the upper side of the storage frame 11.

[0028] When in use, the door 101 of the truck compartment 1 is opened, the motor drives the screw 14 to rotate, and then the slide plate 15 drives the box body 16 to move, so that the box body 16 is completely moved out of the truck compartment 1. When loading, the staff will place two storage boxes 11 filled with vegetables under the box body 16, and then the electric scissor-type telescopic frame 17 in the box body 16 drives the moving plate 18 to move downward until it contacts the upper ends of the two storage boxes 11, so that the electromagnet 181 is energized to generate magnetic force to absorb the storage boxes 11, and the storage boxes 11 are lifted up by the electric scissor-type telescopic frame 17, and the motor drives the screw 14 to rotate, so that the storage boxes 11 enter the interior of the truck compartment 1, so that the staff does not need to carry and place, thereby reducing manpower costs;

[0029] There is a gap between the left and right bearing platforms 12 for the electric scissor-type telescopic frame 17 to pass through. The width of the truck compartment 1 can store two storage frames 11 placed on the left and right. When the storage frames 11 are placed on the upper side of the bearing platform 12, the middle parts of the storage frames 11 abut against each other to improve stability.

[0030] After loading is completed, the movable plate 18 can be located above the uppermost and outermost storage frame 11, which can facilitate closing of the compartment door 101.

[0031] The carrier plate 12 is provided with a fixing assembly;

[0032] The fixing assembly includes a cavity 2 opened by a bearing platform 12, a slide rod 21 is provided on the upper wall of the cavity 2 to slide forward and backward, a pressure plate 22 is provided in the cavity 2 to slide up and down, the slide rod 21 is hinged with a hinge rod 23, the lower end of the hinge rod 23 is hinged with the upper side of the pressure plate 22, a first spring 24 is provided between the lower side of the pressure plate 22 and the bottom wall of the cavity 2, a push plate 25 is connected to the front end of the slide rod 21, a slot is provided at the front end of the bearing platform 12, and a push block 26 matching the push plate 25 is provided on the inner wall of the door 101;

[0033] The upper wall of the freight car 1 is also provided with a fixing assembly;

[0034] When the door 101 is opened, the pressure plate 22 is located inside the cavity 2 under the elastic force of the first spring 24, so as not to hinder the movement of the moving plate 18;

[0035] After loading is completed, the staff closes the compartment door 101, and the push block 26 on the inner side of the compartment door 101 enters the cavity 2 through the slot, abuts against the push plate 25, and pushes the push plate 25 to move backward, thereby driving the slide bar 21 to slide backward, and driving the pressure plate 22 to slide downward through the hinge rod 23, so that the pressure plate 22 abuts against the upper end of the storage frame 11, and fixes the multiple storage frames 11 inside the truck compartment 1, which can prevent the storage frames 11 from moving during transportation;

[0036] The upper wall of the truck compartment 1 is also provided with a fixing assembly for fixing the storage frame 11 placed on the upper bearing platform 12 .

[0037] The pressing plate 22 is provided with a water cavity 3 matching the storage frame 11, a plurality of nozzles are arranged at the bottom of the water cavity 3, a water delivery pipe 31 is arranged on the side wall of the pressing plate 22, the water delivery pipe 31 is connected with the water cavity 3 through a pipeline, and a blocking component is arranged on the pipeline;

[0038] The plugging assembly includes a rectangular groove 32 formed in the pressure plate 22, a plugging block 33 for plugging the pipeline is slidably disposed in the rectangular groove 32, a second spring 34 is disposed between the upper side of the plugging block 33 and the upper wall of the rectangular groove 32, and an abutment rod 35 is connected to the lower side of the plugging block 33;

[0039] After the storage frame 11 is placed in the truck compartment 1, the plurality of water chambers 3 on the pressure plate 22 will correspond to the storage frame 11;

[0040] The storage frame 11 is provided with a water storage tank, and the water storage tank is provided with a water pump, which is connected to the delivery pipe 31 through a hose. During the transportation of vegetables, the water pump is started to deliver the clean water in the water storage tank to the water cavity 3 through the delivery pipe 31, and finally sprayed from a plurality of nozzles onto the vegetables on the upper side of the storage frame 11 to keep the vegetables moisturized.

[0041] After the pressure plate 22 moves downward and abuts against the upper end of the storage frame 11, the abutting rod 35 will abut against the frame wall of the storage frame 11, pushing the blocking block 33 to move upward in the rectangular groove 32, canceling the blockage of the pipeline, so that the clean water in the delivery pipe 31 can enter the water cavity 3. Therefore, when the storage frame 11 does not fill the truck compartment 1, there will be no storage frame 11 on the lower side of the water cavity 3. At this time, the abutting rod 35 is not blocked by the storage frame 11, so the blocking block 33 blocks the pipeline, and the clean water in the delivery pipe 31 cannot enter the cavity 3, which can save water resources.

[0042] The left and right sides of the movable plate 18 are provided with cleaning components, which include a groove 4 provided at the end of the movable plate 18, a rotating shaft 41 is rotatably installed in the groove 4, an elastic telescopic rod 42 is fixed in the middle of the rotating shaft 41, a cleaning brush 43 is connected to the end of the elastic telescopic rod 42, and the rotating shaft 41 is provided with a rotating member;

[0043] The rotating member includes a mounting groove 44 provided at the rear side of the moving plate 18, a rotating shaft 41 extends into the mounting groove 44 and is connected to a gear 45, a rack 46 meshing with the gear 45 is slidably provided in the mounting groove 44, a third spring 47 is provided between one side of the rack 46 and the side wall of the mounting groove 44, a push rod 48 is connected to the other side of the rack 36, three groups of linearly distributed bosses 49 are provided on the side wall of the truck compartment 1, two bearing platforms 12 separate the truck compartment 1 into three storage cavities, and the three groups of bosses 49 are respectively located in the middle of the three storage cavities;

[0044] When the movable plate 18 is loading or unloading goods, it moves forward and backward in the truck compartment 1, and its upper side will contact the lower wall of the loading platform 12 or the upper wall of the truck compartment 1, leaving space for the storage frame 11 on the lower side of the movable plate 18;

[0045] When there is no cargo inside the truck compartment 1, the bottom of the truck compartment 1 can be cleaned by the cleaning assembly, that is, the height of the movable plate 18 is controlled by the electric scissor-type telescopic frame 17 so that it is located in the middle of the storage cavity, and the push rod 48 will be located on the same horizontal plane as the plurality of bosses 49. In this way, when the movable plate 18 moves forward from the inside of the truck compartment 1, the push rod 48 contacts the boss 49, pushing the push rod 48 to move, driving the rack 46 to move in the mounting groove 44, driving the rotating shaft 41 to rotate through the gear 45, and then the cleaning brush 43 rotates. It contacts the side wall of the truck compartment 1 and the surface of the load-bearing platform 12, pushing the impurities on the surface to the middle of the truck compartment 1. When the push rod 48 leaves the boss 49, the elastic force of the third spring 47 pushes the rack 46 to reset, so that the movable plate 18 is moved from the three storage chambers in sequence, and the impurities on the surface of the load-bearing platform 12 can be cleaned and dropped to the middle of the compartment. Finally, the bottom of the movable plate 18 is controlled by the electric scissor-type telescopic frame 17 to contact the bottom of the truck compartment 1. The movable plate 18 moves forward, and the impurities can be pushed forward, realizing automatic cleaning of the interior of the truck compartment.

[0046] The elastic telescopic rod 42 can be extended and retracted, so that the cleaning brush 43 can be in close contact with the side wall of the carriage and the surface of the bearing platform.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
