Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This utility model provides, for example Figures 1-5 The image shows a dump box for a self-unloading semi-trailer.

[0046] Example 1: Includes a housing 101, a partition, a heat insulation mechanism, a refrigeration mechanism, a first air supply mechanism, a second air supply mechanism, and an adjustment mechanism. The partition is located inside the housing 101, and the heat insulation mechanism is located between the housing 101 and the partition. The heat insulation mechanism is used to prevent external heat from entering the interior of the partition. The refrigeration mechanism is located at the top of the partition, the first air supply mechanism is located at the top of the partition, and the second air supply mechanism is located on both sides of the partition. The adjustment mechanism is used to control the connection between the second air supply mechanism and the first air supply mechanism. With the arrangement of the first and second air supply mechanisms, the second air supply mechanism can evenly distribute cold air from both sides of the cargo box to the cargo. At the same time, with the cooperation of the adjustment mechanism, the cold air can flow only from the first air supply mechanism, that is, flow to the top of the cargo. Thus, the required air supply method can be selected according to the actual situation of the cargo, improving applicability.

[0047] The divider includes a divider frame 102, which is fixedly connected to the inner wall of the box 101. The refrigeration mechanism is located at the top of the divider frame 102. The divider frame 102 divides the space inside the box 101 into two areas. The area between the box 101 and the divider frame 102 is used to house the refrigeration mechanism, the first air supply mechanism, and the second air supply mechanism. The interior of the divider frame 102 is used to house goods. The two areas do not interfere with each other, thus improving the stability of the use of the cargo box.

[0048] The refrigeration mechanism includes a mounting bracket 201 and an air conditioner 202. The mounting bracket 201 is fixedly connected to the top of the inner wall of the box 101. The air conditioner 202 is installed on the inner wall of the mounting bracket 201. The first air supply mechanism is located at the bottom of the air conditioner 202. The air conditioner 202 generates cold air when it is working. Then, the cold air is delivered to the interior of the partition frame 102 through the first air supply mechanism and the second air supply mechanism to refrigerate the goods. The mounting bracket 201 is electrically connected to an external power supply through an external switch, which facilitates the operator to control the mounting bracket 201 and improves the safety and convenience of operating the mounting bracket 201.

[0049] The first air supply mechanism includes an air outlet duct 301 and a first horizontal pipe 302. The air outlet duct 301 is fixedly connected to the bottom end of the mounting bracket 201 and is connected to the output end of the air conditioner 202. The second air supply mechanism is connected to the air outlet duct 301. An adjustment mechanism is set inside the air outlet duct 301. The first horizontal pipe 302 is fixedly connected to the outer wall of the air outlet duct 301. Multiple first air outlets 303 are fixedly connected to the bottom end of the first horizontal pipe 302. One end of the first air outlet 303 is fixedly connected to the top end of the partition frame 102. The cold air generated by the air conditioner 202 flows downward through the air outlet duct 301, then enters the first horizontal pipe 302, and finally is discharged downward through the multiple first air outlets 303, so that cold air can be sent into the partition frame 102 from the top.

[0050] The second air supply mechanism includes a second horizontal pipe 401 and a third horizontal pipe 403. The second horizontal pipe 401 is fixedly connected to the outer wall of the air outlet pipe 301. A vertical pipe 402 is fixedly connected to the end of the second horizontal pipe 401 away from the air outlet pipe 301. The third horizontal pipe 403 is fixedly connected to the vertical pipe 402. Multiple second air outlets 404 are fixedly connected to the outer wall of the third horizontal pipe 403. One end of the second air outlet 404 is fixedly connected to the outer wall of the partition frame 102. The cold air entering the air outlet pipe 301 can be diverted into the second horizontal pipe 401, then into the vertical pipe 402, and then into the multiple third horizontal pipes 403. Finally, it is discharged through the second air outlet 404, so that cold air can be sent into the partition frame 102 from both sides, ensuring the uniformity of cold air distribution.

[0051] Example 2:

[0052] Compared to Embodiment 1, the adjustment mechanism includes a rotating ring 501, a docking hole 502, and a rotating mechanism. The rotating ring 501 is rotatably disposed on the inner wall of the air outlet duct 301, and the docking hole 502 is symmetrically opened on the inner wall of the rotating ring 501. The rotating mechanism is disposed at the bottom end of the docking hole 502. The rotating mechanism causes the rotating ring 501 to rotate. When the docking hole 502 coincides with the second horizontal pipe 401, the cold air in the air outlet duct 301 can be diverted into the second horizontal pipe 401. When the docking hole 502 does not coincide with the second horizontal pipe 401, the cold air in the air outlet duct 301 cannot enter the interior of the second horizontal pipe 401, thereby improving the ease of operation of the second air supply mechanism.

[0053] The rotating mechanism includes a first connecting ring 601, a third connecting ring 605, and a positioning mechanism. The first connecting ring 601 is rotatably disposed inside the air outlet duct 301. A connecting rod 602 is symmetrically and fixedly connected to the top end of the first connecting ring 601 and the bottom end of the rotating ring 501. A top groove 603 is opened at the top end of the inner wall of the partition frame 102. A second connecting ring 604 is fixedly sleeved at the bottom end of the outer wall of the first connecting ring 601. The third connecting ring 605 is fixedly sleeved on the outer wall of the second connecting ring 604. A second limiting ring 607 is fixedly sleeved on the inner wall of the third connecting ring 605. The bottom end of the outer wall of the air outlet duct 301 is fixedly... A first limiting ring 606 is fixedly connected to the first limiting ring 606, and a second limiting ring 607 is located below the first limiting ring 606. By limiting the first limiting ring 606 with the second limiting ring 607, the first connecting ring 601 will not fall out of the air outlet pipe 301. Then, the second connecting ring 604 will rotate by rotating the third connecting ring 605, and then the first connecting ring 601 will rotate. Then, through the connection of the connecting rod 602, the rotating ring 501 will rotate, thereby improving the convenience of the adjustment mechanism. The positioning mechanism is located between the second limiting ring 607 and the first limiting ring 606.

[0054] The positioning mechanism includes steel balls 702, springs 703, and locking holes 704. The top of the second limiting ring 607 has locking cavities 701 arranged in a ring array. The steel balls 702 are locked inside the locking cavities 701. The springs 703 are located inside the locking cavities 701 and above the steel balls 702. The locking holes 704 are located at the top of the first limiting ring 606. In this embodiment, there are four steel balls 702. When the first connecting ring 601 rotates 90 degrees, the steel balls 702 can be locked into a new locking hole 704 and a locking sound will be made. This makes it convenient for the operator to judge the rotation angle of the third connecting ring 605. At the same time, the compression of the steel balls 702 by the springs 703 makes the steel balls 702 press tightly against the inner wall of the locking holes 704, which can position the rotating ring 501, thereby improving the stability of the adjustment mechanism.

[0055] Example 3:

[0056] Compared to Embodiment 1, the heat insulation mechanism includes a foam board 801, which is disposed between the box 101 and the partition frame 102. By filling the space between the box 101 and the partition frame 102 with the foam board 801, external heat can be blocked, ensuring the loss of cold air inside the partition frame 102.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
