In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0030] Combine the following Figure 1-Figure 6 The dump truck compartment of the embodiment of the utility model is described.

[0031] The embodiment of the first aspect of the utility model provides a dump truck compartment, such as Figures 1 to 3 As shown, the dump truck compartment includes a compartment body, which includes a compartment body 100 and a compartment door 200 arranged on one side of the compartment body 100; a cleaning mechanism 300 is arranged on the inner wall of the compartment body 100, and the cleaning mechanism 300 includes a driving component 310 and a material guide 320, the driving component 310 is arranged on the inner wall of the compartment body 100, the material guide 320 is connected to the driving component 310, and the material guide 320 has a cleaning portion 321 that cooperates with the bottom plate of the compartment body 100, and the driving component 310 is used to drive the material guide 320 to move along the plane where the bottom plate is located between a first position and a second position, in the first position, the material guide 320 is close to the side plate of the compartment body 100, and in the second position, the material guide 320 is away from the side plate of the compartment body 100.

[0032] It is understandable that if Figure 1 As shown, when the compartment body 100 is loading or unloading, the driving assembly 310 makes the material guide member 320 be located at the first position close to the side plate. At this time, the material guide member 320 retracts to the angle between the side plate and the bottom plate of the compartment body 100, and the material guide member 320 is used for material guiding. When the remaining tailings of the compartment body 100 cannot be unloaded, the driving assembly 310 makes the material guide member 320 move from the first position to the second position, as shown in FIG. Figure 2 As shown; during the movement of the material guide member 320 from the first position to the second position, the material guide member 320 extends relative to the side plate, and the cleaning portion 321 at the bottom of the material guide member 320 cleans the tailings on the compartment body 100.

[0033] It should be noted that the driving assembly 310 drives the material guide member 320 to extend relative to the side plate to clean up the tailings in the later stage of unloading. The tailings cleaning does not require the compartment body 100 to be reset to a horizontal state, and there will be no hidden danger to personnel safety. In addition, the inclined compartment body 100 is more conducive to the unloading of the tailings on the compartment body 100, thereby improving the unloading efficiency.

[0034] It should be noted that when cleaning the tailings on the compartment body 100 , the driving assembly 310 can drive the material guide member 320 to move back and forth between the first position and the second position for multiple times to improve the cleaning effect of the tailings.

[0035] The dump truck compartment provided by the embodiment of the utility model is provided with a cleaning mechanism 300 on the compartment body 100. The driving assembly 310 of the cleaning mechanism 300 drives the material guide member 320 to move along the plane where the bottom plate of the compartment body 100 is located, so as to clean the tailings on the bottom plate of the compartment body 100, and under the action of gravity of the compartment body 100 in an inclined state, the cleaned tailings are automatically unloaded from the compartment body 100.

[0036] It should be noted that in the related art, a guide plate is installed on the dump truck to guide the loading and unloading of materials. However, for small sandy soil particles or viscous materials with high moisture content, the friction between the particles and the bottom plate and the molecular force result in residues left after unloading, which requires manual cleaning, which is inefficient and also easily leads to safety hazards. The utility model provides a movable guide member 320 in the compartment body 100. When loading, the guide member 320 is retracted to the edge of the bottom plate for guiding the materials. When unloading, the guide member 320 is driven to move by the drive assembly 310 to clean the tailings. Thus, the guide plate has the functions of guiding the materials and cleaning the tailings, and there are no safety hazards in the tailings cleaning process.

[0037] In one embodiment of the present invention, Figure 3 As shown, the material guide member 320 includes a material guide plate, and a plurality of teeth are provided at the lower end of the material guide plate. The plurality of teeth form a cleaning portion 321 to clean the tailings left on the bottom plate of the compartment body 100 during the movement of the material guide plate.

[0038] In one embodiment of the utility model, there is a preset angle between the guide plate and the bottom plate. Optionally, the angle between the guide plate and the bottom plate can be a right angle, and the guide plate is vertically arranged above the bottom plate. Of course, the angle between the guide plate and the bottom plate can be any angle.

[0039] Furthermore, the angle between the guide plate and the bottom plate is an acute angle to improve the tail cleaning effect. For example, the guide plate is arranged at an angle relative to the bottom plate, the angle between the guide plate and the bottom plate is an acute angle, and the lower end of the guide plate is away from the side plate of the compartment body 100, the upper end of the guide plate is close to the side plate, and when the guide plate is in the first position, the upper end of the guide plate is against the side plate, and the drive assembly 310 is hidden on the back side of the guide plate. It should be noted here that when the guide plate is in the first position, the surface of the guide plate close to the side plate is the back side, and a storage space for accommodating the drive assembly 310 is formed between the back side of the guide plate and the side plate.

[0040] It should be noted that if an additional cleaning device is provided in the compartment body 100, the cleaning device will be larger due to the longer size of the compartment body 100, thereby occupying more internal space of the compartment body 100, thereby reducing the interior of the compartment body 100, resulting in a decrease in the amount of material loaded in the compartment body 100. At the same time, the cleaning device may interrupt the support beam of the compartment body 100, resulting in a decrease in the overall strength of the compartment body 100. In the compartment of the dump truck provided by the embodiment of the utility model, when the guide plate is in the first position, the drive assembly 310 is hidden on the back side of the guide plate and does not occupy additional space. The guide plate can be used for guiding materials and can also be used to clean the remaining materials on the bottom plate of the compartment body 100 after unloading, without the need for additional cleaning devices.

[0041] In one embodiment of the present invention, Figure 3As shown, the driving assembly 310 includes a driving component 311 and a lifting frame 312. The driving component 311 is arranged on the side plate of the compartment body 100. One end of the lifting frame 312 is connected to the output of the driving component 311, and the other end of the lifting frame 312 is connected to the material guide plate; the lifting frame 312 switches between the extended state and the folded state under the action of the driving component 311. When the lifting frame 312 is in the folded state, the material guide member 320 is in the first position. When the lifting frame 312 is in the extended state, the material guide member 320 is in the second position, so that the lifting frame 312 drives the material guide member 320 to move between the first position and the second position under the action of the driving component 311.

[0042] Optional, such as Figure 3 As shown, the driving component 311 includes a mounting plate 3111 arranged on the side plate and a driving cylinder 3112 arranged on the mounting plate 3111. The driving cylinder 3112 can be a driving oil cylinder or a driving electric cylinder. After the unloading is completed, the driving cylinder 3112 on the back of the guide plate is controlled by the control valve group. The driving cylinder 3112 is used to push the guide member 320 forward, clean the tailings on the bottom plate of the compartment body 100, and unload the tailings by gravity by tilting the compartment body 100.

[0043] like Figure 3 and Figure 4 As shown, the lifting frame 312 includes at least two connecting rod components hinged in sequence, the connecting rod components include a first connecting rod 3122 and a second connecting rod 3123 hinged in the middle, the first connecting rod 3122 and the second connecting rod 3123 of two adjacent connecting rod components are hinged, the first connecting rod 3122 of one of the connecting rod components located on the outermost side is hinged to the mounting plate 3111, and the second connecting rod 3123 of one of the connecting rod components is connected to the output of the driving cylinder 3112; the second connecting rod 3123 of the other connecting rod component located on the outermost side is hinged to the material guide plate, and the first connecting rod 3122 of the other connecting rod component is slidably connected to the material guide plate.

[0044] For example, the lifting frame 312 includes two connecting rod components hinged in sequence, and the connecting rod components include a first connecting rod 3122 and a second connecting rod 3123 hinged in the middle, the first connecting rod 3122 and the second connecting rod 3123 are cross-arranged, and the two connecting rod components are respectively a first connecting rod component and a second connecting rod component, a first end of the first connecting rod 3122 of the first connecting component is hinged to the mounting plate 3111, and a first end of the second connecting rod 3123 of the first connecting component is connected to the output of the driving cylinder 3112; the second end of the first connecting rod 3122 of the first connecting component is hinged to the first end of the second connecting rod 3123 of the second connecting component, the second end of the second connecting rod 3123 of the first connecting component is hinged to the first end of the first connecting rod 3122 of the second connecting component, the second end of the second connecting rod 3123 of the second connecting component is hinged to the material guide plate, and the first end of the first connecting rod 3122 of the second connecting component is slidably connected to the material guide plate.

[0045] Furthermore, the mounting plate 3111 is provided with a first slide rail, and the first end of the second connecting rod 3123 of the first connecting rod component is connected to a first slider slidably arranged on the first slide rail, and the first slider is adjacent to the output of the driving cylinder 3112. The driving cylinder 3112 drives the first slider to move on the first slide rail to realize the switching of the lifting frame 312 between the extended state and the folded state.

[0046] Furthermore, the material guide plate is also provided with a second slide rail 322, and the second slide rail 322 is parallel to the first slide rail. The second end of the first connecting rod 3122 of the second connecting rod component is connected to the second slider 323 slidably set on the second slide rail 322, so that when the driving cylinder 3112 drives the second connecting rod 3123 of the first connecting component to move along the first slide rail, the second end of the first connecting rod 3122 of the second connecting rod component is driven to move on the second slide rail 322.

[0047] In a preferred embodiment of the present invention, each driving assembly 310 includes two lifting frames 312, and the two lifting frames 312 are arranged side by side to improve the stability of the movement of the lifting frames 312. Furthermore, the middle hinge positions of the first connecting rod 3122 and the second connecting rod 3123 of the two lifting frames 312 are rotatably connected through a first pin; and the ends of the first connecting rod 3122 located at the outermost sides of the two lifting frames 312 are rotatably connected through a second pin, and the first slider or the second slider can be set on the second pin.

[0048] like Figure 5 and Figure 6 As shown, the cleaning mechanism 300 includes a plurality of drive assemblies 310 arranged side by side, and the plurality of drive assemblies 310 are arranged at equal intervals.

[0049] It is understandable that when the length of the material guide 320 is long, each cleaning mechanism 300 includes a plurality of drive assemblies 310 arranged side by side, and the plurality of drive assemblies 310 drive the material guide 320 to move between the first position and the second position, so as to improve the stability of the movement of the material guide 320. For example, the cleaning mechanism 300 includes three drive assemblies 310 arranged side by side, and the three drive assemblies 310 are arranged at equal intervals along the length of the material guide 320.

[0050] It should be noted that the material guide member 320 can also be divided into multiple sections along the length direction, each section is connected to a driving component 310, so that each section of the material guide member 320 is driven by a driving component 310, and the multiple sections of the material guide member 320 are respectively driven by multiple corresponding driving components 310, and the multiple driving components 310 can work synchronously or independently.

[0051] In one embodiment of the present invention, the side panel includes a left side panel, a right side panel and a front side panel, and at least one of the left side panel, the right side panel and the front side panel is provided with a cleaning mechanism 300. It should be noted that the front side panel is the side panel opposite to the door 200.

[0052] It can be understood that the compartment body 100 includes a left side panel, a right side panel and a front side panel. The cleaning mechanism 300 can be set on one of the left side panel, the right side panel and the front side panel, or on any two of the left side panel, the right side panel and the front side panel, or on all of the left side panel, the right side panel and the front side panel.

[0053] For example, Figure 1 and Figure 2 As shown, the left and right plates of the compartment body 100 are both provided with a cleaning mechanism 300; for the cleaning mechanism 300 on the left plate, the material guide 320 is in a first position, the material guide 320 is against the left plate, and in a second position, the material guide 320 is away from the left plate; for the cleaning mechanism 300 on the right plate, the material guide 320 is in a first position, the material guide 320 is against the right plate, and in a second position, the material guide 320 is away from the right plate; the material guide 320 moves in the left and right directions under the drive of the driving assembly 310; the first slide rail on the mounting plate 3111 and the second slide rail 322 of the material guide 320 are arranged in the front-to-back direction.

[0054] It should be noted that the left and right plates of the compartment body 100 are both provided with a cleaning mechanism 300, and when the material guide 320 is in the second position, the material guide 320 is located in the middle of the left and right directions, and there is a distance between the material guide 320 on the left and right plates to avoid collision between the material guide 320 on the left and right plates when they are in the second position, so that the travel of the material guide 320 in the left and right directions is less than half of the left and right width of the compartment body 100. Further, a stopper may be provided on one of the material guides 320 to avoid collision between the material guide 320 on the left and right plates.

[0055] It is understandable that, in the previous stage of loading and unloading, the driving cylinder 3112 is in an extended state, the lifting frame 312 is in a folded state, the material guide 320 connected to the left side plate is retracted to the angle between the left side plate and the bottom plate of the compartment body 100, and serves as a material guide, and the material guide 320 connected to the right side plate is retracted to the angle between the right side plate and the bottom plate of the compartment body 100, and serves as a material guide. When the residual tailings of the compartment body 100 cannot be unloaded after unloading, the control valve or controller controls the driving cylinder 3112 to retract, the lifting frame 312 to extend, and the material guide 320 to extend. The bottom of the material guide 320 has a cleaning portion 321 to clean the tailings on the bottom plate of the compartment body 100.

[0056] Further, such as Figure 4 As shown, a connecting member 324 is provided on the back of the material guide member 320, and the connecting member 324 is used to connect the lifting frame 312, and the material guide member 320 is arranged in an inclined manner. For example, the connecting member 324 is a connecting rod with a triangular cross section, and the second slide rail 322 is provided on the connecting member 324.

[0057] Optionally, the material guiding member 320 and the connecting member 324 are formed as an integral structure, and a reinforcing rib plate is provided between the material guiding member 320 and the connecting member 324 .

[0058] An embodiment of the second aspect of the utility model provides a dump truck, which includes a moving mechanism and a dump truck compartment provided by any of the above embodiments; wherein the compartment is arranged on the moving mechanism.

[0059] It should be noted that the types of dump trucks in this embodiment include but are not limited to excavators, dump trucks, hook machines, cranes, muck trucks, dump trucks, etc.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
