Referring to fig. 1 to 3, a schematic structural diagram of the garbage dumping device, a state diagram of the released garbage collection box, and a state diagram of the garbage collection box when it is dumped are shown respectively in an embodiment of the present invention. An embodiment of the present invention provides a garbage dumping device, which comprises a frame 100, a first driving member 200, a second driving member 300, a third driving member 400, a garbage collection box 500, and the like. This device is emptyd to rubbish can install on the sanitation car, and parts such as the brush cleaner on the sanitation car clean the road surface to collect the storage through rubbish collection box 500 to rubbish. After cleaning, the garbage is conveyed to a garbage recycling point to be dumped.

The garbage collection box 500 is used for storing garbage and comprises a box body 510 and a box door 520, wherein a pouring opening 511 is formed in the side portion of the box body 510, and the box door 520 is arranged on the side portion of the box body 510, and the top end of the box door is rotatably connected with the box body 510. When the door 520 is closed, the pouring port 511 is closed, and when the door 520 is opened, the garbage in the box body 510 can be poured out through the pouring port 511.

The bottom of the garbage collection box 500 is provided with a bracket 700, and the garbage collection box 500 is supported by the bracket 700. The first driving member 200 is fixedly connected with the frame 100, the bracket 700 is connected with the power output end of the first driving member 200, and the bracket 700 and the garbage collection box 500 can be driven by the first driving member 200 to move relative to the frame 100 so as to reach one side of the frame 100 and avoid other parts at the top of the garbage collection box 500, thereby facilitating the dumping of garbage.

Meanwhile, the garbage collection box 500 is connected to the power output end of the second driving member 300, and the garbage collection box 500 can be driven to rotate by the second driving member 300 so that the dumping port 511 thereof is brought from the state shown in FIG. 2 to the inclined state shown in FIG. 3.

Meanwhile, the garbage collection box 500 is connected to the power output end of the third driving member 400, and the door 520 of the garbage collection box 500 can be driven to rotate relative to the box 510 by the third driving member 400, so that the dumping opening 511 can be opened for dumping.

Further, the first driving member 200 can drive the garbage collection box 500 and the bracket 700 to move to one side of the frame 100. For example, the first driving member 200 may be a linear motor, an air cylinder, an electric push rod, or the like, and may drive the bracket 700 to move horizontally outward.

Alternatively, the first driving member 200 may drive the garbage collection box 500 and the bracket 700 to rotate to one side of the frame 100. Such as in the manner shown in the drawings, the garbage collection box 500 and the bracket 700 are rotated outwardly and upwardly. When adopting this kind of mode, height when rubbish collection box 500 emptys is great, if the dustbin height of rubbish recovery point is great, can be better formation dodge to accomplish smoothly and emptys.

Specifically, the bracket 700 is connected to the power output end of the first driving member 200 through the link assembly 600. The first driving member 200 may be a linear motor, an air cylinder or an electric push rod, which can push the connecting rod assembly 600 to rotate the garbage collection box 500 outwards and upwards. This link assembly 600 can form the parallelogram mechanism, can improve the stationarity when garbage collection box 500 rotates.

Specifically, the connecting rod assembly 600 includes a first connecting rod 610 and a second connecting rod 620. The first link 610 and the second link 620 have the same length and are parallel to each other. The first link 610 has a top end rotatably coupled to the frame 100 and a bottom end rotatably coupled to the bracket 700. Similarly, the second link 620 has a top end rotatably connected to the frame 100 and a bottom end rotatably connected to the bracket 700. Moreover, the first link 610 is sleeved with a rotating block 611, the rotating block 611 and the first link are fixedly connected through a threaded fastener, and the rotating block 611 is rotatably connected with the power output end of the first driving member 200. Alternatively, the second link 620 may be rotatably connected to the power output end of the first driving member 200.

In the initial state shown in fig. 1, the first link 610 and the second link 620 are both in the vertical state. When the first driving member 200 pushes the first link 610, the first link 610 rotates clockwise relative to the frame 100, the second link 620 rotates clockwise, and the garbage collection box 500 is driven by the link assembly 600 to rotate clockwise and lift up to the state shown in fig. 2 and 3.

The box 510 is rotatably connected to the bracket 700 via a rotating shaft, the second driving member 300 is fixed to the bracket 700, and the power output end thereof is rotatably connected to the box 510. The second driving member 300 may be a linear motor, an air cylinder, or an electric push rod. If the second actuator 300 pushes the container 510, the container 510 is rotated counterclockwise with respect to the bracket 700 from the state shown in FIG. 2 to the state shown in FIG. 3 with the pouring spout 511 facing downward.

Alternatively, the second driving member 300 may be fixed to the case 510, and the power output end thereof may be rotatably connected to the bracket 700.

The third driving member 400 is fixed to the box 510, and the power output end thereof is rotatably connected to the box door 520. The third driving member 400 may be a linear motor, an air cylinder, or an electric push rod. If the third actuator 400 pushes the door 520, the door 520 rotates clockwise with respect to the container 510 from the state shown in FIG. 2 to the state shown in FIG. 3 to open the pouring spout 511.

Alternatively, the third driving member 400 may be fixed to the door 520, and the power output end thereof may be rotatably connected to the cabinet 510.

When the garbage collection box 500 is dumped, the first driving member 200 pushes the first link 610 to rotate the bracket 700 and the garbage collection box 500 clockwise with respect to the frame 100. The garbage collection bin 500 is then pushed by the second driving member 300 to rotate counterclockwise with respect to the bracket 700 until the dumping port 511 faces downward. Then, door 520 is pushed by third actuator 400 to rotate clockwise with respect to container 510, thereby opening pour spout 511. At this time, the garbage in the bin 510 drops down by gravity. In order to ensure that the garbage located at the bottom of the box 510 can be discharged, the rotation angle needs to be as large as possible when the garbage collection box 500 is driven by the second driving member 300 to rotate counterclockwise relative to the bracket 700.

After the garbage is dumped, the door 520 is pulled by the third driving member 400 to rotate counterclockwise relative to the box 510, and the dumping port 511 is closed. And the second driving member 300 pulls the garbage collection box 500 to rotate clockwise with respect to the bracket 700, so that the bottom of the garbage collection box 500 is attached to the bracket 700. The bracket 700 is pulled by the first driving member 200, so that the bracket 700 and the garbage collection box 500 are reset by rotating counterclockwise.

When pouring spout 511 is provided at the side of container 510, the bottom of container 510 is a single plate without any gap, as compared to some methods of providing pouring spout 511 at the bottom of container 510, and the possibility of liquid in the garbage leaking downward through pouring spout 511 to the lower part thereof can be reduced.

Preferably, a sealing strip may be installed between the box 510 and the door 520 to further improve the sealing performance therebetween and reduce the possibility of liquid in the garbage flowing out through a gap therebetween.

In addition, after the garbage is dumped, when the third driving member 400 pulls the box door 520 to close the dumping opening 511, the box door needs to be pulled in place to tightly abut against the box body 510, so that the sealing strip between the box door and the box body is compressed, and the sealing effect is better.

In another embodiment of the present invention, there is provided a road surface cleaning device, which can be a sanitation vehicle, comprising the above garbage dumping device. In the advancing process of the sanitation truck, the road surface garbage is cleaned and gathered by components such as a cleaning brush and the like, and the garbage enters the garbage collection box 500 through the matching of the garbage collection device. When the garbage in the garbage collection box 500 is full, the sanitation vehicle is driven to a garbage collection point, and the garbage is automatically dumped.

Referring to fig. 4 to 6, a schematic structural diagram of a garbage collecting device, a schematic structural diagram of a rolling brush assembly, and a schematic structural diagram of a part of the rolling brush assembly according to another embodiment of the present invention are respectively shown. The garbage collection device comprises a rolling brush assembly 800 and a suction assembly 900, and garbage on the road surface is collected into the garbage collection box 500 through the cooperation of the rolling brush assembly 800 and the suction assembly 900.

Specifically, the brush roll assembly 800 includes a brush roll 810, a fourth driver 820, a trash holding box 830, and the like. The rolling brush 810 is disposed in the garbage storage box 830 and exposed from an opening 8311 disposed at the bottom of the garbage storage box 830, and elastically abuts against the road surface. The fourth driving member 820 is fixedly connected to the trash holding box 830, and the rolling brush 810 is connected to a power output end of the fourth driving member 820, so that the rolling brush 810 can be driven to rotate by the fourth driving member 820. The rolling brush 810 rotates in the opposite direction to the wheels of the sanitation vehicle.

Since the rolling brush 810 elastically abuts against the road surface and the rolling brush 810 and the road surface are in an abutting state, the garbage in front of the rolling brush 810 is blocked by the rolling brush 810 and cannot leak from the road surface through the rolling brush 810. And the space between the roll brush 810 and the inner sidewall of the trash holding box 830 is limited, so that the trash is rolled up upward when the roll brush 810 rotates, rotates counterclockwise in the trash holding box 830, and reaches the upper space in the trash holding box 830 from the road surface.

The suction assembly 900 comprises a suction member 910 and a suction pipe 920, wherein the suction member 910 can be a suction fan, and the suction pipe 920 can be a plastic hose. The straw 920 should have good wear resistance and strength to prevent the straw 920 from being damaged when hard particles such as stones are inhaled. The suction assembly 900 and the garbage collection box 500 are positioned above the rolling brush assembly 800, and the garbage collection box 500 and the rolling brush assembly 800 are communicated with each other through a suction pipe 920. A suction port (not shown) of the suction member 910 communicates with the garbage collection bin 500 to provide a negative pressure to the garbage collection bin 500, so that the garbage rolled up by the rolling brush 810 to the upper space inside the garbage temporary storage bin 830 is sucked into the suction pipe 920 and then into the garbage collection bin 500.

Specifically, the rolling brush 810 may be elastically connected to the trash holding box 830 by an elastic member 860. The elastic member 860 may be a hard spring. The elastic member 860 is in tension, and the rolling brush 810 tends to move downward by its resilience, so as to abut against the road surface.

Further, the roller brush assembly 800 further includes a transmission member 840, and the roller brush 810 is connected to the power output end of the fourth driving member 820 through the transmission member 840. The fourth driving member 820 drives the roller brush 810 to rotate through the transmission member 840. The fourth driver 820 may be a rotary motor or an air cylinder. The garbage temporary storage box 830 is provided with a connecting plate 850, and the transmission member 840 is fixedly connected with the connecting plate 850. Hooks are respectively arranged at two ends of the elastic piece 860, hanging holes (not shown in the figure) are respectively arranged on the garbage temporary storage box 830 and the connecting plate 850, and the hooks at two ends of the elastic piece 860 are respectively hung in the hanging holes on the garbage temporary storage box 830 and the connecting plate 850.

The drive member 840 may be a belt drive member. For example, the transmission member 840 includes a driving pulley 841, a driving pulley 841 and a belt 843, the driving pulley 841 is connected to a power output end of the fourth driving member 820, the driving pulley 841 is connected to a rotating shaft of the roll brush 810, and the belt 843 is sleeved on the driving pulley 841 and the driving pulley 841. The belt 843 is not a rigid member, and can ensure that the roller brush 810 has a certain degree of freedom in the vertical direction and can move a small distance in the vertical direction.

Furthermore, the radius of the driving pulley 841 and the radius of the driving pulley 841 can be changed, so that the rolling brush 810 rotates at a proper speed, and garbage can be rolled up more easily.

Preferably, the fourth driver 820, the transmission member 840, the connection plate 850, and the like are disposed outside the trash storage box 830. A through extending hole 8312 is formed in a sidewall of the garbage temporary storage box 830, and a rotation shaft of the rolling brush 810 extends outward from the extending hole 8312 and is connected to the driving pulley 841.

Although the above components may be disposed inside the trash storage box 830, if the components are disposed outside, the internal space of the trash storage box 830 is not occupied, so that the space between the rolling brush 810 and the side wall of the trash storage box 830 is smaller, and the trash is more easily rolled up.

The protruding hole 8312 has a larger size in the vertical direction than in the horizontal direction to provide a moving space for the rotation shaft of the drum brush 810. When the roller brush 810 encounters uneven road surface, the resilient force of the elastic member 860 can drive the roller brush 810 to move in the vertical direction, so as to be attached to the road surface all the time.

Preferably, the surface of the rolling brush 810 can be covered with a layer of bristles, and the bristles can further clean the road surface when the rolling brush 810 rotates, so that the cleaning effect is optimized.

The trash temporary storage bin 830 includes a first trash temporary storage portion 831 and a second trash temporary storage portion 832, and the first trash temporary storage portion 831 is located at one side of the second trash temporary storage portion 832 and is communicated with the second trash temporary storage portion 832. The first trash buffer 831 and the second trash buffer 832 may be fixed by welding or screw fasteners. The rolling brush 810 is disposed in the first trash temporary storage 831, and the suction pipe 920 is connected to the second trash temporary storage 832. The first waste buffer 831 is located before the second waste buffer 832 in the forward direction of the waste collection device. The garbage sequentially passes through the first garbage temporary storage 831 and the second garbage temporary storage 832 and then enters the suction pipe 920.

When the rolling brush 810 rotates, the garbage in front of the rolling brush is rolled up to the upper space of the first garbage temporary storage 831, and under the action of centrifugal force, the garbage is thrown into the second garbage temporary storage 832 and falls down to the bottom of the second garbage temporary storage 832 under the action of gravity. When the garbage reaches between the first garbage temporary storage 831 and the second garbage temporary storage 832, the suction force of the suction pipe 920 makes the garbage more easily enter the second garbage temporary storage 832 instead of the garbage attached to the first garbage temporary storage 831 rotating continuously and falling on the road again. In addition, some fine particles that cannot be rolled up by the roller brush 810 will also enter the suction pipe 920 under the suction force.

Preferably, a suction tube 920 is connected to the bottom end of the second waste buffer 832. The waste is deposited at the bottom of the second waste buffer 832 by gravity. Thus, coupling the suction tube 920 to the bottom end of the second trash buffer 832 may allow trash to be more easily drawn into the suction tube 920. If the suction pipe 920 is connected to the middle portion of the second trash temporary storage unit 832, the amount of the trash temporarily stored in the second trash temporary storage unit 832 is small and is lower than the lower end of the suction pipe 920, and when the suction force in the suction pipe 920 is insufficient, the trash may be retained in the second trash temporary storage unit 832 and cannot be removed.

Preferably, the second temporary garbage storage 832 is provided with a material taking door 8321, and the material taking door 8321 is positioned at a side portion of the main body of the second temporary garbage storage 832, and is rotatably connected with the second temporary garbage storage 832 through a hinge. A latch may be provided to secure the free end of the material extraction door 8321 to the main portion of the second waste buffer 832. If the size of some waste is larger than the diameter of the suction pipe 920, it cannot be drawn into the suction pipe 920. At this point, the latch may be unlatched and the waste manually removed to avoid clogging the straw 920 and affecting subsequent waste collection.

Preferably, a periphery of the blocking plate 833 is disposed at the bottom of the first temporary garbage storage 831, and the blocking plate 833 can block the garbage entering the first temporary garbage storage 831 from the front, and limit the moving area of the garbage, so that the garbage reaches the roller brush 810 and is prevented from moving around and leaving the inside of the first temporary garbage storage 831.

Further, in the forward direction of the garbage collection device, the position of the flapper 833 located at the front end is lower than the position of the flapper 833 located at the other position. Therefore, the garbage can enter the first garbage temporary storage 831 more easily, and after entering the first garbage temporary storage 831, the garbage is not easy to move in other directions and leave the first garbage temporary storage 831.

Preferably, the flap 833 is resilient. When the garbage collection device moves and encounters an uneven road surface, the baffle 833 can deform so as to avoid rigid collision with the road surface, and the baffle 833 can be protected and is not easy to damage.

Preferably, the roller brush assembly 800 further comprises a fifth driving member (not shown), the waste storage bin 830 is connected to a power output end of the fifth driving member, and the waste storage bin 830 can be moved in a vertical direction by the driving of the fifth driving member to adjust the position of the roller brush assembly 800.

If an obstacle is encountered during the cleaning process, the fifth driving element can drive the garbage temporary storage box 830 to move upwards to lift the rolling brush assembly 800, so as to prevent the rolling brush assembly 800 from colliding with the obstacle and causing damage to the rolling brush assembly 800. When the obstacle passes, the rolling brush assembly 800 is put down.

Specifically, a first rope 870 is further provided, and the first rope 870 may be a steel wire rope. The fifth driving part can be a linear motor, an air cylinder or an electric push rod and other common driving parts. One end of the first rope 870 is connected to the power output end of the fifth driving member, and the other end is fixedly connected to the top of the first temporary garbage storage 831.
