[0022] The embodiments of the application disclose a kind of closed container with self-unloading function. Refer to Figures 1-7, including the box assembly 1 and the chassis 5, so that the box assembly 1 is connected on the transport vehicle through the chassis 5. Specifically, the rear end of the box assembly 1 is hingedly connected with the rear end of the chassis 5, so that the rear end of the box assembly 1 can rotate relative to the chassis 5. The rear end of the box assembly 1 is fixedly connected with the turnover upper seat 17 through two three-port molding, and the rear end of the chassis 5 is detachably fixedly connected with the turnover lower seat 13 through bolts. The turnover upper seat 17 and the turnover lower seat 13 are rotationally connected through the turnover shaft 7, so that the rear end of the box assembly 1 and the rear end of the chassis 5 are rotationally connected together through the turnover upper seat 17, the turnover lower seat 13 and the turnover shaft 7, thereby realizing that the box assembly 1 can rotate relative to the chassis 5 with the turnover shaft 7 as the axis.
[0023] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 5 , the front end of the chassis 5 is detachably fixedly connected with the guiding device base 9 through bolts, and the front end of the box assembly 1 is detachably fixedly connected with the guide plate 8, so that when the box assembly 1 is placed on the chassis 5, the guiding device base 9 abuts against the guide plate 8, thereby limiting the box assembly 1 and the chassis 5 by using the guiding device base 9 and the guide plate 8, avoiding that the box assembly 1 is misaligned when placed on the chassis, and affecting the transportation of the box assembly 1.
[0024] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 5 , the front end of the chassis 5 and the front end of the box assembly 1 are connected through the lifting oil cylinder 2, so that the front end of the box assembly 1 can be lifted and lowered relative to the chassis 5 through the lifting of the lifting oil cylinder 2, thereby enabling the rear end of the box assembly 1 to rotate relative to the chassis 5 with the turnover shaft 7 as the axis. Specifically, the front end of the chassis 5 is detachably fixedly connected with the lifting oil cylinder base 11 through bolts, and the front end of the box assembly 1 is detachably fixedly connected with the mounting plate 14 through bolts. The lifting oil cylinder upper seat 22 is detachably fixedly connected with the mounting plate 14 through bolts. The two ends of the lifting oil cylinder 2 are hingedly connected with the lifting oil cylinder base 11 and the lifting oil cylinder upper seat 22 respectively, so that the two ends of the lifting oil cylinder 2 are connected together with the front end of the chassis 5 and the front end of the box assembly 1 through the lifting oil cylinder base 11 and the lifting oil cylinder upper seat 22, thereby enabling the front end of the box assembly 1 to be lifted and lowered relative to the chassis 5 by the extension and contraction of the lifting oil cylinder 2, and realizing that the box assembly 1 can be overturned around the turnover shaft 7.
[0025] Referring to Figure 1 , Figure 4 , Figure 5The middle part of the base frame 5 is connected to the middle part of the housing assembly 1 via a stabilizer 6, which increases the stability of the connection between the base frame 5 and the middle part of the housing assembly 1. Specifically, the lower end face of the middle part of the housing assembly 1 is detachably fixed to the upper stabilizer 16 by bolts, and the middle part of the base frame 5 is detachably fixed to the lower stabilizer 12 by bolts. The two ends of the stabilizer 6 are rotatably connected to the upper stabilizer 16 and the lower stabilizer 12 by connecting shafts, so that the stabilizer is connected to the base frame 5 and the housing assembly 1 together through the upper stabilizer 16 and the lower stabilizer 12, thereby increasing the stability of the connection between the base frame 5 and the housing assembly 1 using the stabilizer 6. The stabilizer 6 is composed of a first connecting frame and a second connecting frame. The first connecting frame and the second connecting frame are rotatably connected together. The first connecting frame is rotatably connected to the housing assembly 1, and the second connecting frame is rotatably connected to the base frame 5. This allows the stabilizer 6 to be folded or unfolded in the structure of the first connecting frame and the second connecting frame when the front end of the housing assembly 1 is raised or lowered.
[0026] Reference Figure 4 , Figure 5 , Figure 6 The front end of the base frame 5 is equipped with a pair of pin assemblies 4. A pair of housing positioning sleeves 15 are detachably fixed to the housing assembly 1 by bolts, so that when the housing assembly 1 is placed on the base frame 5, the pin assemblies 4 partially insert into the housing positioning sleeves 15 to lock the base frame 5 and the housing assembly 1 into place. The pin assembly 4 includes a pin cylinder 26, a pin cylinder seat 27, a pin seat 24, and a pin shaft 23. The pin cylinder seat 27 and the pin seat 24 are detachably fixed to the front crossbeam of the base frame 5 by bolts, so that the pin cylinder seat 27 and the pin seat 24 are connected to the front crossbeam of the base frame 5 to form a whole. The two ends of the pin cylinder 26 are detachably fixed to the pin cylinder seat 27 and the pin shaft 23 by bolts, so that the pin cylinder 26 is connected to the base frame 5 through the pin cylinder seat 27, so that the extension and retraction of the pin cylinder 26 drives the pin shaft 23 to move relative to the base frame 5. The pin shaft 23 is movably installed within the pin seat 24, allowing the pin shaft 23 to move against the pin seat 24 while the pin seat 24 supports and limits the pin shaft 23. The pin shaft 23 corresponds to the housing positioning sleeve 15, causing the pin cylinder 26 to extend and drive the pin shaft 23 into the housing positioning sleeve 15. When the housing assembly 1 is seated on the base frame 5, the pin cylinder 26 extends, driving the pin shaft 23 to move to both sides of the base frame 5 until the pin shaft 23 is inserted into the housing positioning sleeve 15, thereby locking the base frame 5 and the housing assembly 1 together to form a whole, preventing the housing assembly 1 from detaching from the base frame 5. When the housing assembly 1 needs to be lifted, first retract the pin cylinder 26, which will drive the pin shaft 23 to completely exit the housing positioning sleeve 15, thereby releasing the rigid connection between the housing assembly 1 and the front end of the base frame 5. Then, the lifting cylinder 2 can be extended to lift the housing assembly 1.
[0027] With reference to Figure 7 The rear end of the box assembly 1 is hinged with a rear door 19 through a rear door hinge 18, so that the rear door 19 is hinged with the box assembly 1 to form an integral whole. The inner edge of the rear door 19 is detachably fixed with a sealing strip 20 through bolts, so that the gap between the rear door 19 and the box assembly 1 is sealed by the sealing strip 20, and the inside of the box assembly 1 is ensured to be airtight. The rear door 19 is detachably fixed with a lock through bolts, and the lock is a common container door lock in the market, so that the rear door 19 is locked with the box assembly 1 through the lock, thereby realizing the sealing of the inside of the box assembly 1 by the rear door 19.
[0028] In the above embodiments, the device elements are conventional device elements unless otherwise specified, and the structure setting mode, working mode or control mode are conventional setting mode, working mode or control mode unless otherwise specified.
[0029] The above embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
