AI Technical Summary
The threaded rods of existing refrigerated van transport semi-trailers are prone to frost, resulting in the inability to drive the slider to move, and the defrost scraper contacts too much with the inner wall of the car, which is severely worn and has a short service life.
A refrigerated van transportation semi-trailer is designed. The loading mechanism can close the protective screw when not in use to prevent it from being exposed to the inner surface of the refrigerated van. The scraper of the defrosting mechanism drives the scraper to move and contact the inner wall of the refrigerated van by rotating the second screw to reduce wear.
It effectively avoids the screw being exposed to the inner surface of the refrigerated compartment for a long time, extends the service life of the screw, and extends the service life of the defrosting scraper by reducing the contact between the scraper and the inner wall of the refrigerated compartment.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerated transportation, in particular to a refrigerated box-type transportation semitrailer. Background Art
[0002] Cold chain transportation refers to the transportation of goods at a certain temperature throughout the entire transportation process, whether it is loading and unloading, changing the mode of transportation, changing the packaging equipment, etc. In the cold chain transportation process, refrigerated van transport semi-trailers are often used. When in use, the products to be transported are directly loaded into the semi-trailer compartment. The temperature control device in the compartment can control the temperature in the compartment to reduce the ambient temperature of the product, thereby refrigerating the product;
[0003] For example, the patent website discloses a refrigerated van transport semi-trailer (publication number: CN220639658U). This device uses a driving motor to drive a threaded rod to rotate and drive a slider to move to drive the loading rack to move. However, the threaded rod is exposed in the refrigerated compartment, and its surface is prone to frost. Once frosted, the rotating threaded rod cannot drive the slider to move. At the same time, the defrost scraper of this device is always in contact with the inner wall of the compartment, resulting in the defrost scraper always scraping the inner wall of the compartment when the loading rack moves, regardless of whether there is frost on the inner wall of the compartment, which leads to large wear of the defrost scraper and a short service life. Therefore, technical personnel in this field have proposed a refrigerated van transport semi-trailer. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a refrigerated box transport semitrailer. The loading mechanism of the device can seal and protect the screw when not in use, and the scraper does not contact the inner wall of the refrigerated box when not defrosting, thereby solving the problems in the above background.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a refrigerated van transport semitrailer, comprising:
[0006] A refrigerated compartment, which is used to store and refrigerate goods;
[0007] A semitrailer, wherein the semitrailer is used for transporting the device;
[0008] A loading mechanism, which is installed inside the refrigerated compartment for loading and unloading cargo;
[0009] The loading mechanism comprises two moving seats installed on the bottom surface of the refrigerated compartment, a moving groove is provided on the side of each moving seat, a motor is installed on the side of each moving seat on the side of the refrigerated compartment, a driving end of each motor extends into the corresponding moving groove, and a first screw rod whose end is rotatably connected to the inner wall of the moving groove is installed on the driving end of each motor, a threaded seat is provided on each screw rod, a loading shelf is installed between the two threaded seats, two L-shaped frames are correspondingly installed on the upper surface of each moving seat, an electric push rod is installed on the lower surface of each L-shaped frame, and a baffle plate adapted to the moving groove is installed on the lower end of the two electric push rods on each moving seat;
[0010] A defrost mechanism is installed on the loading mechanism for defrosting the inner side wall of the refrigerated compartment.
[0011] As a further technical solution of the utility model, the refrigerated compartment is installed on a semi-trailer.
[0012] As a further technical solution of the utility model, the defrosting mechanism includes two L-shaped plates installed on the upper surface of the loading shelf, and a mounting plate is installed on the upper end of each of the L-shaped plates.
[0013] As a further technical solution of the utility model, a threaded barrel is installed on each of the mounting plates, a second screw rod is arranged in each of the threaded barrels, and a knob is installed at the end of each of the second screw rods.
[0014] As a further technical solution of the utility model, the other end of each of the second screw rods passes through the mounting plate and is rotatably mounted with a scraper, and a limiting rod passing through the mounting plate is mounted above the second screw rod on the side of each of the knobs.
[0015] Beneficial Effects
[0016] The utility model provides a refrigerated box transport semitrailer. Compared with the prior art, it has the following advantages:
[0017] Beneficial effects:
[0018] 1. A refrigerated box transport semitrailer. When the loading mechanism of the device is not in use, the electric push rod can be extended to drive the baffle to descend to close the moving groove on the side of the moving groove, so that the screw is wrapped in the moving groove to prevent the screw from being exposed to the inner surface of the refrigerated box for a long time and frost will affect the next use of the screw.
[0019] 2. A refrigerated box transport semitrailer, in which the scraper of the defrosting mechanism of the device does not contact the inner wall of the refrigerated box. When the inner wall of the refrigerated box needs to be defrosted, the second screw can be rotated to drive the scraper to move and contact the inner wall of the refrigerated box, and then the defrosting operation can be performed. Furthermore, the scraper of this device does not need to contact the inner wall of the refrigerated box throughout the whole process, thereby reducing its wear and tear and extending its service life.

[0033] Two moving seats 2 are installed at the bottom edge of the refrigerated compartment 1, each moving groove 3 is opened on the side of the corresponding moving seat 2, each motor 4 is installed on the side of the refrigerated compartment 1 and is on one side of the corresponding moving seat 2, each first screw 5 is rotatably installed inside the corresponding moving groove 3 and the end is fixedly connected to the driving end of the motor 4 on one side, each threaded seat 6 is arranged on the corresponding first screw 5, the loading shelf 7 is installed between the two threaded seats 6, each group of two L-shaped frames 8 is installed on the upper surface of the corresponding moving seat 2, each electric push rod 9 is installed on the lower surface of the corresponding L-shaped frame 8, and each baffle 10 is installed at the lower end of the two electric push rods 9 on the corresponding moving seat 2 and is adapted to the moving groove 3;
[0034] The two motors 4 drive the two first screws 5 to rotate, and the two rotating first screws 5 drive the threaded seats 6 thereon to move, and the two moving threaded seats 6 drive the loading racks 7 to move, so that the loading racks 7 can be used to transport goods during loading and unloading, which is more convenient and quick, and improves the loading efficiency of the device. At the same time, when not in use, all the electric push rods 9 extend to drive the two baffles 10 to descend to close the two moving grooves 3, and wrap the two first screws 5 in the moving grooves 3 to prevent frost on their surfaces from affecting the next use;
[0035] like Figure 1-4 As shown, the defrosting mechanism includes an L-shaped plate 11, a mounting plate 12, a threaded barrel 13, a second screw 14, a knob 15, a scraper 16, and a limit rod 17;
