DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0025] In combination with Figures 1 to 3According to the transport equipment 100, the drainage mechanism 20 is arranged in the garbage can 10, the sewage generated in the garbage can 10 can be collected through the water guide groove 21 and the drainage hole 101, and then the sewage is guided to the sewage tank 30 outside the garbage can 10 through the drainage hole 101, so that the sewage treatment is facilitated.

[0026] According to the transport equipment 100, the drainage mechanism 20 is arranged in the garbage can 10, the sewage generated in the garbage can 10 can be collected through the water guide groove 21 and the drainage hole 101, and then the sewage is guided to the sewage tank 30 outside the garbage can 10 through the drainage hole 101, so that the sewage treatment is facilitated.

[0027] For example, when the garbage can 10 is filled with a material with a large expansion coefficient, especially recyclable materials, the sewage in the box needs to be completely drained. However, the material with a large expansion coefficient will hinder the flow of sewage in the box. Therefore, by arranging the water guide groove 21 in the garbage can 10, the material with a large expansion coefficient will not hinder the flow of sewage, and the sewage discharge effect is improved.

[0028] In combination with Figure 3In some embodiments of the present application, the plurality of drainage holes 101 are located at one end of the water guide groove 21, and the plurality of drainage holes 101 are arranged at the lowest position in the horizontal direction of the bottom wall of the garbage can 10. Thus, the water in the water guide groove 21 can flow naturally to the drainage hole 101 at the lowest position based on the action of gravity. The plurality of drainage holes 101 are opposite to the sewage tank 30 in the up-down direction, and the water at the drainage hole 101 can flow downward into the sewage tank 30. That is, the sewage can flow from the water guide groove 21 into the drainage hole 101, and then into the sewage tank 30. When the garbage in the garbage can 10 is full or the garbage is loaded with a material having a large expansion coefficient, the garbage will not block the flow of sewage from one end of the garbage can 10 to the other end with the sewage tank 30, thereby improving the collection effect of the sewage.

[0029] Of course, when the garbage in the garbage can 10 does not hinder the flow of sewage, the sewage can also flow directly into the sewage tank 30 through the drainage hole 101, thereby facilitating the collection of the sewage.

[0030] Optionally, the water guide groove 21 can be located at the side of the garbage can 10, which can avoid the garbage from blocking the water guide groove 21 and facilitate the improvement of the water guide effect.

[0031] Of course, the one end of the water guide groove 21 can also be directly communicated with the sewage tank 30. The water guide groove 21 can be arranged in a downward inclined form towards the sewage tank 30, so that the sewage can naturally flow into the sewage tank 30.

[0032] In combination Figure 3 In some embodiments of the present application, the water guide groove 21 comprises a flow guide part and a flow guide plate 211. The flow guide plate 211 is arranged on the flow guide part, and the flow guide plate 211 is provided with a plurality of water inlets 201 communicated with the flow guide part. Specifically, the flow guide plate 211 can guide the sewage into the flow guide part, thereby facilitating the collection of the sewage. The flow guide plate 211 can also cover the flow guide part, so that the sewage in the flow guide part can flow to the sewage tank 30 without being affected by the garbage or the expansion of the garbage.

[0033] Further, in some embodiments of the present application, the first side of the flow guide plate 211 is connected to the side wall of the garbage can 10, and the second side of the flow guide plate 211 is connected to the bottom wall of the garbage can 10. The flow guide plate 211 is configured in a form gradually inclined downward from the first side to the second side, and the water inlet 201 is arranged at the second side of the flow guide plate 211. Thus, the sewage flowing down from the side wall of the garbage can 10 can be guided to the water inlet 201 to enter the water guide groove 21. The flow guide plate 211 can also avoid the formation of water accumulation at the intersection of the side wall and the bottom wall when the sewage flows from the side wall of the garbage can 10 to the bottom wall of the garbage can 10, but directly guide the sewage into the water inlet 201. The water inlet 201 is located at the side of the flow guide plate 211 close to the bottom wall of the garbage can 10, so that the water inlet 201 is communicated with the bottom wall of the garbage can 10, and the sewage on the bottom wall of the garbage can 10 is also easy to enter the water guide groove 21 from the water inlet 201.

[0034] In combination Figure 3 The deflector 211 protrudes from the bottom wall of the garbage can 10, and the highest point of the deflector 211 is higher than the water inlet 201, so that the garbage in the garbage can 10 can be prevented from blocking the water inlet 201, thereby improving the guiding effect of the sewage.

[0035] In combination Figure 3 In order to improve the collection effect of the sewage, the water guide groove 21 can be arranged on opposite sides of the garbage can 10. In some embodiments of the utility model, the water guide groove 21 includes the first guide groove 21a and the second guide groove 21b arranged opposite in the second direction, and the sewage tank 30 is connected to the end of the first guide groove 21a and the second guide groove 21b in the first direction, and the first direction is perpendicular to the second direction. The first direction can be the length direction or the front-back direction of the garbage can 10, and the second direction can be the width direction or the left-right direction of the garbage can 10. That is, the first guide groove 21a and the second guide groove 21b can be arranged on the left and right sides of the garbage can 10 and extend in the front-back direction of the garbage can 10, and the sewage tank 30 can be arranged on the front bottom or the rear bottom of the garbage can 10. In this way, in the garbage can 10, the sewage at the front and rear ends of the garbage can 10 can be guided into the sewage tank 30 through the guide grooves on the left and right sides of the garbage can 10. When the garbage in the garbage can 10 is less, or the expansion coefficient of the garbage in the garbage can 10 is small, the sewage can directly flow to the sewage tank 30 located at the low position through the bottom wall of the garbage can 10. When the garbage can 10 is filled with substances with a large expansion coefficient, the sewage at one end of the garbage can 10 away from the sewage tank 30 cannot directly flow to the sewage tank 30 through the bottom wall of the garbage can 10, and then the sewage can be guided from one end of the garbage can 10 to the sewage tank 30 located at the other end through the first guide groove 21a and the second guide groove 21b on the left and right sides of the garbage can 10, thereby achieving the discharge of the sewage. In addition, the guide grooves are arranged on the left and right sides of the garbage can 10, and the sewage can flow into a guide groove nearby, thereby improving the collection effect of the sewage.

[0036] In some embodiments of the utility model, the first guide groove 21a and the second guide groove 21b are provided with a plurality of water inlets 201 arranged at intervals in the first direction, and the sewage can enter the first guide groove 21a from the water inlet 201 of the first guide groove 21a, or enter the second guide groove 21b from the water inlet 201 of the second guide groove 21b, thereby improving the collection effect of the sewage and reducing the leakage of the sewage.

[0037] In combination Figure 3In some embodiments of the utility model, the first guide groove 21a and the second guide groove 21b form a confluence area 110, the confluence area 110 is opposite to the sewage tank 30, and the confluence area 110 is provided with a plurality of drain holes 101 connected with the sewage tank 30. Specifically, the bottom wall of the garbage can 10 is provided with a plurality of drain holes 101 connected with the sewage tank 30, and the plurality of drain holes 101 are arranged in the confluence area 110. The confluence area 110 can converge the sewage guided by the first guide groove 21a and the second guide groove 21b to the confluence area 110, and also can converge the sewage flowing from the middle region of the bottom wall of the garbage can 10 to the confluence area 110, thereby facilitating the collection of the sewage. The sewage reaching the confluence area 110 can directly enter the sewage tank 30 from the drain hole 101 based on the gravity, thereby facilitating the collection of the sewage.

[0038] In some embodiments of the utility model, the confluence area 110 is arranged at the lowest position in the horizontal direction of the bottom wall of the garbage can 10, thereby facilitating the flow of the sewage tank 30 in the confluence area 110.

[0039] In combination Figure 1 And Figure 2 In some embodiments of the utility model, the sewage tank 30 is provided with a drain port arranged at the bottom or lower portion of the sewage tank 30, thereby facilitating the downward flow of the water in the sewage tank 30 and facilitating the discharge of the sewage in the sewage tank 30. Specifically, the sewage tank 30 comprises a sewage discharge pipe 31 and an adjusting valve 32, one end of the sewage discharge pipe 31 is connected with the drain port of the sewage tank 30, thereby guiding the discharge of the sewage, and the sewage discharge pipe 31 can extend for a certain distance or extend in a predetermined direction, thereby facilitating the collection of the sewage discharged from the sewage tank 30. For example, in combination Figure 1 The sewage tank 30 is arranged below the garbage can 10, and the drain port is arranged below the sewage tank 30, thereby when the position of the drain port is low or it is difficult to enter the bottom of the transfer equipment 100 to collect the discharged sewage, the sewage outlet can be guided to the side of the transfer equipment 100 by connecting the sewage discharge pipe 31, thereby facilitating the drainage operation.

[0040] The other end of the sewage discharge pipe 31 is connected with the adjusting valve 32, and the adjusting valve 32 can open or close the drain port, thereby when the transfer equipment 100 is transported, the drain port can be closed, and the sewage will not flow out during the transfer. When the sewage needs to be discharged, the adjusting valve 32 is opened, so that the sewage in the sewage tank 30 can be discharged.

[0041] Optionally, the adjusting valve 32 can be in the form of an automatic control switch, thereby improving the automation degree of the transfer equipment 100. For example, when the transfer destination is reached, the adjusting valve 32 is controlled to be opened, so that the sewage in the sewage tank 30 is discharged.

[0042] Of course, the adjusting valve 32 can also be manually controlled, thereby reducing the manufacturing cost of the equipment and facilitating the use and maintenance. For example, in combination Figure 2The adjusting valve 32 is provided with an adjusting switch 321, and an operator controls opening and closing of the adjusting valve 32 by rotating the adjusting switch 321.

[0043] In combination Figure 2 In some embodiments of the present application, in order to improve the cleanliness of the sewage tank 30, the sewage tank 30 can be provided with a cleaning port (not shown in the figure) communicating with the inside of the sewage tank 30, and an operator can inject clean water into the cleaning port to make the clean water or clean water enter the inside of the sewage tank 30 to achieve the cleaning effect. The sewage tank 30 comprises a sealing cover 33 which can open or close the cleaning port. When the sewage tank 30 stores sewage, the sealing cover 33 closes the cleaning port to ensure the sealing of the sewage tank 30 and prevent sewage leakage. When the sewage tank 30 needs to be cleaned, the sealing cover 33 can be opened to clean through the cleaning port.

[0044] In combination Figure 2 The sealing cover 33 can be connected to the sewage tank 30 in a separable manner, that is, the sealing cover 33 is mounted on the sewage tank 30 by means of fasteners 331 and closes the cleaning port, and during operation, the sealing cover 33 is mounted or dismounted by rotating the fasteners 331.

[0045] Alternatively, one side of the sealing cover 33 can be hinged to the sewage tank 30, and the other side can open or close the cleaning port.

[0046] Alternatively, the periphery of the sealing cover 33 or the cleaning port can be provided with a sealing ring to improve the sealing effect when the sealing cover 33 covers the cleaning port.

[0047] In some embodiments of the present application, the cleaning port is arranged along opposite sides of the sewage tank 30, and during cleaning, only one side or both sides can be opened to improve the flexibility during cleaning. During application, a suitable cleaning method can be selected according to the degree of dirtiness of the sewage tank 30.

[0048] Further, during cleaning, the adjusting valve 32 can also be opened to make clean water or clean water discharge through the sewage discharge pipe 31 to clean the sewage discharge port 320. Alternatively, a cleaning tool can be inserted into the sewage discharge pipe 31 for cleaning, and the present application is not limited thereto.

[0049] In combination Figure 4 In some embodiments of the present application, the transfer device 100 further comprises a chassis 40, and the garbage can 10 is arranged on the chassis 40. The garbage can 10 comprises a lower box body 12 and an upper box body 11, and the upper box body 11 is arranged above the lower box body 12. The upper box body 11 is rotatably connected to the lower box body 12 in the up-down direction. Specifically, the rear end of the lower box body 12 is rotatably connected to the chassis 40, and is used for rotating the lower box body 12 in the up-down direction.

[0050] The garbage can 10 of the present application is a box body structure separated in up-down direction,Figure 1 and Figure 4 is a schematic view of the transfer equipment 100 of an embodiment of the present application. The garbage can 10 comprises an upper box body 11, a lower box body 12, a lifting mechanism (for example, a lifting oil cylinder), a compression cavity, a locking mechanism, etc. The upper box body 11 is located at the upper portion of the lower box body 12, and the upper box body 11 is locked with the lower box body 12 during compression to form a storage box. During unloading, the upper box body 11 is separated from the lower box body 12 to facilitate unloading. The lower box body 12 is located at the bottom of the structure and is connected with the compression cavity 101 to form a whole. The lifting mechanism provides power for lifting and lowering of the upper box body 11. The locking mechanism is located at the tail of the structure and performs locking and loosening actions on the upper and lower box bodies 12.

[0051] Figure 4 is a schematic view of unloading, as shown in Figure 4 , after the equipment is fully compressed and filled with the compressed material, the equipment is transferred to a garbage disposal station by the pull arm vehicle 50. During unloading, the pull arm vehicle 50 is powered to lift the upper box body 11 by the lifting mechanism, separate the upper box body 11 from the lower box body 12, and lift the equipment to the unloading state by the pull arm of the pull arm vehicle 50. The compressed material in the box composed of the upper box body 11 and the lower box body 12 is unloaded under the action of gravity.

[0052] The transfer equipment 100 of one specific embodiment of the present application is described below with reference to the accompanying drawings.

[0053] In combination with Figures 1 to 4 , the lower box body 12 of the garbage can 10 is arranged with water guide grooves 21 at the bottom of both sides. The water guide grooves 21 are spaced apart by a water inlet 201. The sewage in the box enters the drainage hole position through the water guide grooves 21. The drainage hole position is the lowest point of the equipment. A sewage tank 30 is arranged below the drainage hole. The sewage tank 30 is used to store sewage. A drainage outlet is arranged at the bottom of the sewage tank 30. The drainage outlet is used to discharge the sewage in the sewage tank 30. Assembly type cleaning ports are arranged at both sides of the sewage tank 30. The cleaning ports are in a sealed state in a normal state and are sealed by a sealing cover 33 to ensure that the sewage tank 30 can store sewage. When the sewage tank 30 needs to be cleaned, the cleaning ports can be disassembled for cleaning operation.

[0054] Specifically, the sewage discharge process is as follows: when the garbage can 10 is fully compressed and filled with a material with a large expansion coefficient, the sewage at the tail of the garbage can 10 cannot normally flow to the drainage hole at the lowest point of the equipment. At this time, the sewage can enter the water guide grooves 21 through the water inlets 201 on the water guide grooves 21 at the bottom of both sides of the lower box body 12. The sewage flows to the drainage hole at the lowest point of the equipment through the water guide grooves 21, enters the sewage tank 30 through the drainage hole, and is discharged through the drainage outlet.
