Description

Self-unloading container with frame turned on one's side in

Technical Field

The utility model relates to a self-unloading container, in particular to a self-unloading container which turns on one's side in a self-frame.

Background

The container is used as an international cargo loading tool, is widely applied to the fields of railways, highways, sea transportation and the like, and is an international modularized transportation mode. Existing containers are 20 feet, 30 feet, 40 feet, 45 feet in length; the device comprises a high box and a low box; there are open top type, self-unloading type etc. special containers.

The transportation amount and mileage of the coal and the powder particle goods in China are very large, most of the coal in the existing market is transported by adopting a common bin-grid semitrailer, an 8.6-meter rear dump truck and a 9.6-meter common car, and only a small part of the coal is transported by adopting a railway. And the problems of serious splashing, unsafe, difficult unloading and the like exist in the vehicle transportation of serious privacy-changing illegal actions of part of dump semitrailers. In recent years, the call for 'bulk change set' in industry is higher and higher, and meanwhile, along with the change of 'bulk change set', the problems of sprinkling, self-unloading, unloading safety and the like also need to be solved.

Dumpers, and particularly dumper containers, have wide demands and remarkable advantages in transportation and unloading of granular (e.g., coal slime, grains, engineering materials such as sand, stone and soil, and the like) and other types of cargoes. In the specific self-unloading setting, the aspects of unloading safety, unloading efficiency, simple operation, high automation degree, small personnel health/danger coefficient, cost saving, service life of a self-unloading setting mechanism, practical application specification and the like are all the common problems to be solved in the freight transportation field for a long time.

The existing self-unloading device is generally divided into three common modes of side turning (unilateral unloading), back turning and middle turning (bilateral unloading), and the three designs also respectively meet different requirements. The side turning is mainly aimed at one side of a storage yard where cargoes need to be unloaded, for example, coal cargoes need to be unloaded in a floor drain; the middle turning provides a double-side unloading mode, and the track through which the vehicle passes is the middle of two stacks of cargoes; and then the turnup is usually directly connected with the fixed-width discharge opening. First, the smooth departure of the vehicle after the unloading is completed is also a matter of consideration when designing the dump mechanism. Secondly, the freight unloading place is often not a flat and tamped station or road surface, but is often complex and changeable in case of uneven ground or loose ground. In practical application process for many years, because the whole container body of the container fully loaded with a large weight (for example, tens of tons) is offset when in rollover, only one bottom edge (or a tire on the side) of the unloading side is taken as a fulcrum, the proportion of rollover safety accidents of the whole vehicle/carriage caused by rollover self-unloading is far higher than that of other unloading modes, and huge property and personnel losses are brought. In addition, due to the problem of poor balance force of the single fulcrum design, the service life of the side-turning type product is relatively short.

In recent years, manufacturers of these particulate material transportation demands are more willing to purchase dump products with a medium or medium turnover arrangement, and in the case of heavy-duty dump products, the case side turnover design is in a trend of being gradually eliminated. However, as mentioned above, due to the limitation of some places or unloading demands, people have to use side-turning self-unloading, and have to bear corresponding safety accident risks, which are very huge in loss of personnel and property.

Disclosure of Invention

Aiming at the existing problems, due to the continuous existence of single-side unloading demands, the utility model changes the conception mode of the original side-turning self-discharging box, and provides a self-discharging container with a side-turning in a frame, which is an open top self-discharging container with a side-turning in a frame, and the top is optionally provided with an automatic or manual tarpaulin system to solve the problem of sprinkling. Meanwhile, the utility model provides a container for unloading goods under the condition that a container body (frame) is not moved on the basis of providing a stable integral frame, particularly a stable bearing type bottom frame consisting of a fixed underframe and side beams, so that the problems of difficult unloading, high energy consumption, high potential safety hazard and the like are solved. The utility model relates to a self-unloading container with a side-turned frame, which effectively solves the defects and problems in the transportation and unloading of the existing powder particle goods such as coal and the like, and expands the functions of the container. The container provided by the utility model realizes the function of unloading (self-unloading) the container to a single side, and the product has the advantages of reasonable, simple and convenient design, better strength of the container body and stronger applicability.

In particular, the present utility model aims to provide a self-unloading container with frame internal side turning, which mainly comprises: the side sill comprises a bottom frame, side beams and at least one internal turning bucket. The bottom frame and the side beams form a bearing type bottom frame structure (the side beams form long edges of the bottom surface of the container), and the inward turning bucket can rotate and lift along one side (unloading side) side beam so as to realize self-unloading (of the cargoes borne on the bottom plate/in the bucket); wherein the varus hopper has a floor which (when not lifted) acts as a floor of the container for carrying the cargo and side dams which, when not lifted, act as at least part of a side dam (lifting side/non-unloading side) of the container.

Wherein, one side (edge) of the bottom plate is rotationally connected with the side beam of the unloading side so as to rotate along the side beam; the other side (edge) of the bottom plate is connected with a side block and is lifted (lifting side) during lifting. The bottom plate and the side rails thus form an inverted bucket with an L-shaped cross section that is inverted inside the container frame.

Further, the inverted bucket also has at least one diagonal draw bar or at least one triangle.

Wherein the diagonal beams are used to connect the bottom plate and the side rails (preferably, the distal/distal ends of the two) for supporting the two. The two inclined-pulling beams are preferably two, and are respectively connected with the sections of the front end and the rear end of the internal turning bucket; there may be a plurality of: one or more pieces are arranged on the same section, or one or more pieces are respectively arranged on different sections of the internal turning bucket.

Wherein the triangular plate is used for connecting one side edge (front end or rear end section) of the bottom plate and the side block and is used for supporting/closing at least one part of end face of the L-shaped groove formed by the bottom plate and the side block, thereby forming a triangular inward turning bucket together with the bottom plate and the side block.

Most preferably, the diagonal braces, the edges of the floor, the edges of the side rails and/or the (unattached) edges of the triangle, which are located on the front or rear cross-section (i.e., the edges connecting the floor and the side rails), are also configured to move substantially against the fixed portion of the tank (e.g., the frame, the front rail, the rear rail, the intermediate rail, etc.) during lifting to act as/effect a scraper and at the same time prevent leakage of cargo.

In view of the total weight of the box, it is preferable that each of the sections of the front and rear ends of the inverted bucket is provided with a diagonal beam connecting the distal ends and the distal ends. From the standpoint of structural stability and protection against particle leakage, triangular plates that close the entire L-shaped cross section of the varus bucket, or at least the entire (edge) length of the bottom plate, are more preferred.

Further, the container also includes a lifting mechanism for rotational lifting of the in-turned cargo bucket (relative to the frame/bottom frame). Of course, the varus bucket may be lifted by other external mechanisms (e.g., a lifting mechanism).

Preferably, the lifting mechanism is a lifting cylinder, and the lifting cylinder is respectively connected with the varus bucket and the bottom frame (side beam and underframe cross beam) and is used for lifting the varus bucket. Each varus bucket is provided with at least one lifting cylinder, preferably two lifting cylinders, which are respectively arranged at the front side and the rear side of the varus bucket; the lifting cylinders are preferably arranged close to the lifting side. The lifting cylinders may be hydraulically, pneumatically or other lifting means/means to effect lifting.

Further, the varus bucket is provided with a chamber/protective cover (arranged according to the number of lifts) which isolates the lifting cylinder from the cargo, is open towards the bottom frame, and accommodates the lifting cylinder. Preferably, the chambers are provided at the front end/side and the rear end/side of the varus hopper. Alternatively, the lifting cylinder may be disposed outside the container body (e.g., outside the front and rear baffles and the side baffles), and the lifting cylinder may be lifted by lifting the varus bucket (e.g., the upper side baffle) or connecting the outer wall of the varus bucket (side baffle) to push the varus bucket.

Preferably, the side beam of the side (unloading side) which is rotatably connected with the varus bucket (bottom plate) is provided with a diversion angle. For the situation that the bottom plate is positioned above the bottom frame (double-layer bottom surface) when the floor is on the floor, the guide angle of the boundary beam is required to be protruded out of the bottom plate frame; for the condition that the bottom plate falls into the bottom frame completely when falling, the diversion angle is set to be the missing angle in the bottom frame, so that the bottom plate in two conditions rotates around the boundary beam to a discharge surface which is flush with the diversion angle and has the same inclination angle after the bottom plate rotates to the required angle.

Further, the bottom plate of the varus bucket is also provided with a bottom beam of an inverse U-shaped structure, the bottom beam is matched with the cross beam of the bottom frame, and the inverse U-shaped bottom beam is sleeved on the cross beam when the bottom plate is not lifted, so that the lower surface of the bottom plate is attached to the bottom frame, the gravity center of the cargo of the container is greatly reduced, and the inverse U-shaped bottom beam can also play a role in deformation resistance of the bottom plate.

Preferably, after the internal turning bucket is lifted, the internal turning bucket can reach a state that an included angle of 40-50 degrees is formed between the bottom plate and the underframe, so that the goods can flow down from all sides in a self-unloading way.

Preferably, the container further comprises at least one intermediate barrier dividing the container into two or more separate compartments, depending on the overall length of the container concerned; each bin is provided with an varus bucket provided by the utility model. Likewise, adjacent two of the varus hoppers are preferably separated by an intermediate partition. For the example of the varus bucket adopting the triangular plates with the whole L-shaped section for sealing the varus bucket, no middle partition plate (considering the weight of the box body) can be arranged between the adjacent varus buckets, and the two triangular plates which are arranged in a pasting way are mutually scraping plates.

Further, the container also comprises a front baffle, a rear baffle, a side baffle and a side baffle small door; the front baffle, the rear baffle, the middle baffle (optional) and the upper side beams of the side baffles are connected with the underframe and the side beams into a whole to form a complete large frame structure. Preferably, the left side and the right side (long sides) of the container body are respectively provided with a side baffle (and an upper side beam thereof), the side baffle at the unloading side is rotationally connected with a side baffle small door, and the lower end of the side baffle small door can be locked with the side beam; the side baffle plate on the lifting side is matched with the side baffle plate of the inward turning cargo bucket, and the side baffle plate form an integral side baffle plate of the container body when the container body is not lifted. Preferably, said side barrier small door on the discharge side is provided with an (remotely controlled) automatic unlocking mechanism and an automatic lifting mechanism. Preferably, the cooperation between the side baffle of the lifting side and the side baffle of the varus bucket is arranged as a chamfer so as to facilitate the lifting of the side baffle. The tailgate is also a connection that can be locked/unlocked to the bottom frame (chassis).

The self-unloading container with the frame turned on one side, provided by the utility model, fundamentally solves the defects of the traditional side turning unloading mode from the following aspects, and provides a brand-new design conception mode with application and development prospects for single-side unloading requirements:

the single-side unloading process of the container product comprises the following steps: after the small side baffle door on the unloading side is opened (electrically), the granular goods originally abutted against the side wall on the side can automatically flow down due to the action of gravity, and the residual goods borne by the bottom plate can continuously flow down along with the rotation of the bottom plate until the angle of repose of the goods is exceeded, so that all the granules are left along the bottom plate to finish self-unloading.

(1) First, and most importantly, the container product of the present utility model has little change in the position (both laterally and longitudinally) of the overall center of gravity of the container during lifting and unloading of the varus hopper. In the whole self-unloading process, the whole frame structure of the container is always kept motionless: the discharge side frame sections are completely free of displacement/deflection, in particular the discharge side frames (bottom side rail, side rail top rail and frame, intermediate rail column sections), and likewise the opposite side (lifting side) frame sections are also free of deflection; and, because the goods are the particulate matter of self-running type, constantly flow out the box in the lifting process for still be in the focus of box/the horizontal direction of the particulate matter heap of bottom plate bearing still, just be located the box frame inside still all the time. Thus, the center of gravity shift of the whole of the cargo + box in the horizontal direction (width direction) is greatly reduced as compared with the center of gravity shift of the conventional whole side-turning box. Moreover, based on continuous gravity flow of the goods and the design of the utility model for only lifting the internal turning-over goods bucket, the gravity center lifting range of the goods and the box body is limited in the height direction because the position of the integral frame is unchanged, and is far smaller than that of the traditional side turning-over box body. The gravity center change of the container product provided by the utility model is greatly reduced in the self-unloading process, so that the stability and the unloading safety of the container body are greatly improved, the container can be more suitable for various complex unloading sites, and the container has great significance for practical application.

(2) On the basis, the design of the container of the utility model does not change the appearance and standard requirements of the existing container products, can integrate the design into the existing container, has no convex objects outside, can completely pass the authentication of relevant departments such as national class society, and the like, can be directly put into large-scale industrial application, has no whistle design of an air pavilion, solves the practical/existing problems of single-side unloading by using the box plate composition and structure of the container, and is simple and efficient.

Besides, the four mushroom nails at four corners required to be installed by regulations and standards are fixed, and the container can be pulled without any connection, namely, the butted skeleton car can be used for transporting the container without any refitting, so that the container has no improved requirements on the existing production line and matched equipment, and can be directly used for realizing standardized and automatic manufacturing.

(3) The container of the present utility model, for the longer case example, is more preferably of the segmented (two or more bins) design: the sectional type inward turning bucket design and the multi-lifting point support can effectively reduce the deformation probability of the bucket bottom plate, the lifting mechanism (such as a hydraulic system) has small energy supply/output requirements, and the service life of the whole product is prolonged; the side-turning risk of the vehicle can be further reduced by carrying out lifting in sections; meanwhile, the deformation rate of the bottom plate of the cargo bucket is reduced, so that the weight of the box body can be reduced (for example, aluminum alloy, nonmetal and the like are selected), the cost is reduced, the total weight of the box body is reduced, and the carrying capacity of products is increased.

In addition, the sectional design is more friendly to operators in practical application. In the actual unloading process, when the container products mounted on the framework vehicle are unloaded, the heavy granular cargoes naturally scatter around the wheels below the vehicle framework after flowing down to a pile, even if the empty vehicle after unloading is driven off site due to overlarge body quantity by using a deflector and the like, additional tractor pulling or loader pushing or jacking translation equipment is generally needed to help the empty vehicle to leave the site, and the unloading efficiency is greatly reduced. In addition, the sectional design provided by the utility model is preferable to firstly discharge goods in a warehouse far away from the position (tail part) of the power vehicle, and after the goods in the warehouse are discharged, the weight of the goods in the front warehouse is just pressed on the driving wheel of the tractor, so that the vehicle is easy to be started and push-pull is not needed. Finally, when the front side bin is unloaded, as the cargoes are few and the resistance is relatively small, the vehicle can be easily driven out, and the whole process can be quickly separated without the help of external force.

(4) The problem of cargo leakage is primarily solved by the self-unloading product, and the main problems of supporting and leakage of the varus bucket are solved by adopting the structural components (such as a bottom plate and a side baffle plate) of the traditional container in the container product structure, and only by simple element addition and proper position selection of the diagonal bracing beam/triangle plate, a stable triangular lifting section is formed and the fixed part is attached to move. Meanwhile, because the granular goods are used as the main service objects of the self-discharging products, the problem that partial granules (such as wet blocks and frozen blocks) are adhered to fixed parts (such as front and rear baffles and the like) can also exist due to the influence of various factors such as climate, temperature and humidity, and at the moment, the thin edges of each attaching motion on the internal turning bucket play a role of a scraping plate, so that the complete self-discharging is completed.

In the container provided by the utility model, the internal overturning cargo bucket enables the inside of the container to be provided with a self-unloading function: when loading, the inward turning cargo bucket falls down to be used as a cargo box for carrying the cargo; when unloading, after opening the side baffle door, the goods can flow a large part automatically, and then the internal turning bucket is lifted from the container under the action of the lifting cylinder, and the container body frame is motionless. The internal turning bucket is lifted to one side and is in a 40-50-degree state, so that the goods can flow downwards to one side completely and are self-unloading, and the whole container is unloaded under the condition of no movement, and the internal turning bucket is very safe. The front baffle, the rear baffle, the middle baffle and the upper side beams of the side baffles are all connected with the underframe and the side beams into a whole to form a complete large frame structure, thereby playing the roles of bottom bearing and box strength of the container. The present utility model may be containers of various length, height dimensions (20 feet, 30 feet, 40 feet, 45 feet, 48 feet, etc.). In order to increase the strength of the box body, and facilitate and rationalize unloading, the internal length direction of the box body can be divided into a plurality of independent inward turning bucket units (one-section type, two-section type, three-section type, four-section type and the like). In addition, common goods can be loaded and unloaded from the small door of the rear baffle plate and also can be loaded and unloaded from the top; the automatic or manual tarpaulin system can also be installed at the top, can effectually be rain-proof or prevent the goods unrestrained, reaches the effect of environmental protection. The utility model provides a self-unloading container with a side-turning frame, which has the advantages of simple structure, high safety and convenient processing.

Detailed Description

The utility model is further described below with reference to the accompanying drawings, namely a self-unloading container with a side turned inside the frame.

It should be noted that "frame rollover" in the present utility model means that the discharge bucket is located substantially always inside the entire frame of the container product during the discharge process, and particularly means a design structure located always inside the frame in the horizontal direction of the entire frame.

Meanwhile, the bottom frame refers to a bottom supporting structure of a rib frame-shaped box body or a box body which is in a shape like a Chinese character 'Wang' or a Chinese character 'jing' -shaped (or a Chinese character 'three' -shaped) extending commonly in the field, and the bottom supporting structure and a bottom plate which is matched with the bottom supporting structure are combined to form the bottom surface of the box body or the box body. The edge beam is a design structure of the edge beam of the bottom supporting structure, is arranged to be attached to the long side of the bottom plate, is connected with the cross beams of the underframe which are mainly arranged in width, and forms a more stable bottom surface structure for being matched with various overturning arrangements of the bottom plate.

Here, a self-unloading container with frame side turning of the present utility model will be described using a two-stage container product (a middle deck 10 divided into two separate in-turned bucket units).

Specifically, as shown in fig. 1-6, the self-unloading container is composed of a front baffle 1, side baffles 2, side baffle small doors 3, a rear baffle 4, a bottom frame 5, side beams 6 (two), an inward turning bucket 7 (two), lifting cylinders 8 (4), turning pins 9 and a middle partition plate 10 (one).

The bottom of the container is made in the form of a fixed side beam 6 (discharge side with angle deflector function) and a bottom frame 5 to form a complete load-bearing bottom frame structure. An inward turning bucket 7 and a lifting cylinder 8 are arranged on the underframe 5. Referring to fig. 1 and 2, the in-turned bucket 7 can be rotatably lifted along the right side beam 6 to effect self-unloading of the cargo carried in the in-turned bucket 7. Preferably, the left side beam 6 is provided with a draft angle (see left-hand enlargement in fig. 1 and 2).

Further, the front baffle 1, the rear baffle 4, the middle baffle 10 and the upper side beams of the side baffles 2 of the container body are all connected with the underframe 5 and the side beams 6 into a whole to form a complete/integral large frame structure, thereby playing roles of bearing the bottom of the container and supporting the strength of the container body. During lifting and self-discharging, the whole frame of the box body does not move, for example, the side baffle plate 2 and the side baffle plate small door 3 at the unloading side/left side are completely motionless during lifting, and only granular goods are dumped and moved leftwards, so that the force for driving the box body to integrally incline towards the left side and even roll over during unloading due to factors such as ground reasons, support and the like is not generated. The left side baffle plate 2 and the right side baffle plate 2 of the container body (and the edge beam at the upper part of the container body) are respectively provided with a side baffle plate small door 3 which is rotatably connected, and the lower end of the side baffle plate small door 3 can be locked/unlocked with the edge beam 6. The right side baffle 2 is matched with the side baffle 7-2 of the varus bucket, and forms an integral side baffle of the container body when the container body is not lifted. The tailgate 4 is also connected to the bottom frame (chassis 5) in a locking/unlocking manner.

Referring to fig. 1-2 and 5-6, the varus bucket 7 is comprised of a varus bucket floor 7-1, a varus bucket side stop 7-2, and a varus bucket diagonal draw beam 7-3. Wherein the varus hopper floor 7-1 (when not lifted) serves as the floor of the container for carrying cargo, and the varus hopper side rails 7-2 serve as at least a portion of the right side barrier of the container when not lifted, both of which may be made of the trim panel technology and materials (or more lightweight materials) used in existing containers and serve as the respective floor and wall panels themselves when carrying cargo.

Wherein, the bottom beam of the bottom plate 7-1 (bottom surface) of the varus bucket is directly sleeved on the cross beam of the underframe 5 (see fig. 6) by adopting a lower U-shaped (reverse U-shaped) structure, thereby enabling the cargo carrying surface (bottom surface) of the varus bucket 7 to be attached on the cross beam of the underframe 5 and greatly lowering the gravity center of the cargo of the container. The left side edge of the inverted bucket bottom plate 7-1 is rotationally connected with the left side edge beam 6 through the inverted pin shaft 9 so as to rotate along the side edge beam 6; the right-hand side connection (which may be welded as one piece, or may be a detachable connection/sealing connection as with the side gate 3) of the inverted bucket floor 7-1, the inverted bucket side gate 7-2 is lifted during lifting.

The side baffle 7-2 of the varus bucket is matched with the right side baffle 2, and forms an integral side baffle of the container body when the container body is not lifted. The cooperation between the side dams 2 and the side dams 7-2 is preferably a chamfer (the tangent point on the inside of the tank is higher than the tangent point on the outside) to facilitate lifting of the side dams 7-2.

The varus bucket diagonal draw beams 7-3 connect the varus bucket floor 7-1 and the varus bucket side rails 7-2 (preferably connect the distal/distal ends) for support of both. The number of the inclined pull beams 7-3 of the varus bucket is preferably two, and the sections of the front end and the rear end of the varus bucket 7 are respectively; there may be a plurality of: one or more pieces are arranged on the same section, or one or more pieces are respectively arranged on different sections of the internal turning bucket. In the embodiment, only the inclined pull beam 7-3 of the inverted bucket is taken as an example to describe the supporting and scraping effects of the inclined pull beam; indeed, a triangle may be used in this example as well (e.g., a triangle is provided between the inverted bucket diagonal draw beam 7-3 and the right angle formed by the right side floor and the side rails in the illustration, thereby forming a "triangular bucket").

Each varus bucket 7 is provided with two lifting cylinders 8, respectively connecting the varus bucket 7 and the cross beam of the underframe 5. Two lifting cylinders 8 are arranged at the front end and the rear end of the varus bucket 7, respectively. As shown in fig. 1 and 2, in order to accommodate the lifting cylinders 8, to isolate them from the cargo and to provide openings for the lifting cylinders to connect to the underframe 5, two chambers are preferably provided on the right of the front and rear ends of the varus bucket 7 (closed towards the interior of the cargo/box and open towards the underframe 5, see also fig. 5) to accommodate the lifting cylinders 8. In fig. 1 and 2, the cylinder support is shown in the chamber, the top of the piston rod of the cylinder 8 is connected to the cross beam of the chassis 5, and in practice the cylinder 8 may be arranged in opposite fashion (fixed to the chassis 5 by the support, the top of the piston rod being connected to a top seat arranged in the chamber).

As shown in fig. 2 and 5, after the varus bucket 7 is lifted, the varus bucket bottom plate 7-1 and the underframe 5 can be in a state of forming an included angle of 40-50 degrees, so that the goods can flow down from all sides in a self-unloading way.

The internal turning bucket 7 lifts and self-unloading process of 40-50 degrees along the left side beam 6, so that the internal turning bucket 7 and the goods therein are still integrally positioned in the box body frame when reaching the highest point, the offset of the integral gravity center of the box body to the left is small, and as the bottom plate is a rigid plate, the goods on the upper surface of the goods stack continuously drop along with the lifting process, and the upward movement amount of the integral gravity center of the box body is also very small.

Furthermore, in addition to the example of a single floor structure formed with the underframe 5 after the varus hopper floor 7-1 is dropped (dropped onto the cross beam) as shown in the sectional view in fig. 1-2, the container of the present utility model may be provided with a double floor structure (as shown in fig. 7-8): that is, the inverted bucket floor 7-1 is positioned on the floor formed by the underframe 5 after it is dropped (preferably with the inverted U-shaped bottom beam also described above fitted over the cross beam of the underframe 5), thereby forming a double floor structure (inverted) dump container. In the example of the double bottom structure, the side sill 6 on the discharge side is provided with a draft angle portion protruding/extending beyond the bottom frame (the lower bottom of the double bottom) and the inner upper edge (upper corner) of the draft angle is rotatably connected to the in-turned bucket floor 7-1 and is flush with the upper surface of the in-turned bucket floor (the upper bottom of the double bottom) at the time of its landing, and the inclination angle of the draft surface is equal to the lifting angle, whereby the same draft discharge effect can be achieved. In this example, other arrangements of the container are the same as the example described above.

The internal turning-over bucket 7 enables the inside of the container to be provided with a self-unloading function, and the internal turning-over bucket 7 falls down when loading; after the side baffle small door 3 is opened during unloading, the goods can flow a large part automatically, then the internal turning bucket 7 is lifted from the inside of the container under the action of the lifting cylinder 8, and the whole container body frame is not moved. The inward turning bucket 7 is lifted to one side to be in a 40-50 degree state, so that the goods can flow downwards to one side to be self-unloading, and the whole container is unloaded under the condition of no movement, and the container is very safe. The present utility model may be containers of various length, height dimensions (20 feet, 30 feet, 40 feet, 45 feet, 48 feet, etc.). In order to increase the strength of the box body, the unloading is convenient and reasonable, the internal length direction can be divided into a plurality of independent inward turning bucket units (one-section type, two-section type, three-section type, four-section type and the like); the common goods can be loaded and unloaded from the small door of the rear baffle 4 and also can be loaded and unloaded from the top.

The self-unloading process of the container structure provided by the utility model comprises the following steps: when the container needs to be unloaded, the small side baffle door 3 is opened, and the cargo automatically flows to one side for a large part under the action of dead weight; after the self-flowing is finished, the internal turning goods bucket 7 is lifted by the lifting cylinder 8 arranged on the underframe 5, the internal turning goods bucket 7 rotates along the turning pin shaft 9 fixed on the side beam 6 (the unloading side has an angle diversion function) on the left side of the box body, and the internal turning goods bucket 7 is in a 40-50 DEG state to one side after being lifted, so that the goods can flow down and be self-discharged to one side completely, and the goods can be discharged to one side completely under the condition that the whole container is not moved.
