[0031] In the related art, when working in areas with uneven ground (slope changes), due to the short length of the shovel plate, the cutting angle of the shovel plate increases, and the angle change at the hinged part between the shovel plate and the cylindrical body is large, resulting in large energy loss of the garbage in the chute, further increasing the resistance of the garbage from entering the cylindrical body from the shovel plate, thereby reducing the garbage collection effect; the support wheel is located behind the mouth of the shovel plate, resulting in the inability of the mouth of the shovel plate to respond to road surface changes (uneven road surface) in a timely manner, causing the mouth of the shovel plate to collide with the road surface, shoveling up small stones to form flying stones, creating a safety hazard, damaging passing vehicles, and the collision causing damage to the mouth of the shovel plate and shortening the service life of the shovel plate. In the vehicle storage state, the entire device rotates upward, blocking the driver's line of sight; when the vehicle storage device rotates, the storage platform also rotates accordingly, and there is also a risk of the garbage rolling down again, affecting the volume of the storage platform; the mouth of the shovel plate cannot be closed, and the rolling garbage is easy to fly out of the shovel plate, posing a safety hazard.

[0032] Therefore, the present utility model provides a garbage collection device and a garbage pickup truck, which can reduce or eliminate the formation of flying stones and eliminate the safety hazards of flying stones or garbage rolling down again; eliminate the problem of the change in the driver's field of vision during vehicle storage.

[0033] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0034] Combined with Figure 1 and Figure 2, The garbage collection device 100 according to an embodiment of the present utility model includes: a storage bin 10 and a collection shovel 20. Specifically, the storage bin 10 includes a cylinder 11 and a storage portion provided inside the cylinder 11. The storage portion can construct a storage space to realize garbage collection. More specifically, the collection shovel 20 extends in the front-rear direction. When the garbage collection device 100 moves forward, the garbage can be shoveled up by the collection shovel 20 and then move backward by inertia. The rear end of the collection shovel 20 is rotatably connected to the cylinder 11. Thus, the garbage on the ground can be collected by the collection shovel 20 and then enter the cylinder 11 from the collection shovel 20. That is to say, the front end of the collection shovel 20 faces the ground and the rear end is connected to the cylinder 11. In this way, the collection shovel 20 can collect the garbage on the ground, and the storage bin 10 can store the garbage collected by the collection shovel 20, thereby realizing garbage collection.

[0035] Further, in combination with Figure 3 , in some embodiments of the present utility model, the garbage collection device 100 further includes a support wheel 23. The support wheel 23 is provided at the front end of the collection shovel 20. The support wheel 23 supports the collection shovel 20 on the ground, and can space the collection shovel 20 at a fixed distance from the ground. Thus, the support wheel 23 can adjust the relative height between the collection shovel 20 and the ground in real time in response to road surface changes, respond to road surface changes in a timely manner, and reduce the small stones shoveled up due to the small distance between the collection shovel 20 and the road surface caused by delayed response. Specifically, by placing the support wheel 23 at the front, a space can be formed between the front end or the shovel mouth of the collection shovel 20 and the ground, and a stable spaced height can be maintained, which can prevent the collection shovel 20 from shoveling small stones on the ground and reduce flying stones. For example, after the small stones enter the device, they can enter the storage portion through the spiral chute of the cylinder 11 at an accelerated speed. Generally, a grid storage cabin door 12 for storing garbage is provided inside the storage portion, and the small stones will fall from the grid of the storage cabin door 12 and be accelerated again, increasing the energy, resulting in the stones flying out of the device. The flying stones may hit the surrounding vehicles and cause safety accidents.

[0036] For the garbage collection device 100 according to an embodiment of the present utility model, by providing the support wheel 23 at the front end of the collection shovel 20, it is possible to avoid shoveling small stones to form flying stones and improve the operation safety.

[0037] Furthermore, the cylinder body 11 extends in the left - right direction and has an opening 101 at the lower part, and garbage can enter the storage space from the opening 101. The rear end of the collection shovel 20 is rotatably connected to the rear - side edge of the opening 101 of the cylinder body 11. When the collection shovel 20 is working, the relative position between the collection shovel 20 and the cylinder body 11 may change. For example, when the ground has a slope or the ground is uneven, the angle between the collection shovel 20 and the ground may change, and the collection shovel 20 can rotate appropriately to adapt to the change of the ground. The collection shovel 20 is connected to the rear side of the cylinder body 11. Thus, the extension distance of the rear end of the collection shovel 20 is relatively long, which can form a transition space, facilitating the smooth transition between the collection shovel 20 and the cylinder body 11. Furthermore, it can reduce the influence of the change of the inclination angle of the collection shovel 20 on the connection part between the collection shovel 20 and the cylinder body 11, improve the garbage collection effect, and can also timely adapt to the change of the distance between the collection shovel 20 and the ground, avoid the interference between the collection shovel 20 and the ground, prevent the collection shovel 20 from shoveling small stones on the road surface to form flying stones and damaging passing vehicles, and at the same time avoid the wear or damage of the collection shovel 20, improving the operation effect of the garbage collection device 100.

[0038] Specifically, in combination with Figure 2 and Figure 7 , in the related art, the shovel plate 20' overlaps at the bottom of the cylinder body 10'. When the inclination angle of the shovel plate 20' becomes larger, when the garbage enters the cylinder body 10' from the shovel plate 20', the angle change at the connection part between the shovel plate 20' and the cylinder body 10' is relatively large, resulting in a large energy loss when the garbage enters the cylinder, so it is more difficult for the garbage to continue to enter the cylinder. In addition, at the overlapping part between the shovel plate 20' and the cylinder body 10', a large change in the inclination of the shovel plate 20' will cause the separation between the shovel plate 20' and the cylinder body 10', thus increasing the resistance for the garbage to enter the cylinder body 10' (see Figure 7 ). In this application, in combination with Figure 2 , the collection shovel 20 is connected to the rear side of the cylinder body 11. In the case of the same shoveling position, in this application, the collection shovel 20 extends further backward, so that the collection shovel 20 has a longer shoveling channel. After the garbage enters the collection shovel 20, the longer shoveling channel is conducive to constructing a smooth transition at the connection part between the collection shovel 20 and the cylinder body 11, and is also conducive to increasing the acceleration of the garbage when it enters the cylinder body 11, thereby reducing the resistance for the collection shovel 20 to enter the cylinder body 11. Especially when the inclination angle between the collection shovel 20 and the ground changes, the angle change between the collection shovel 20 and the cylinder body 11 can be appropriately reduced, so as to reduce the resistance when the garbage enters the cylinder body 11.

[0039] Therefore, by rotatably connecting the rear end of the collecting shovel 20 to the rear side edge of the opening 101 of the cylinder body 11, on the one hand, the connection position between the collecting shovel 20 and the cylinder body 11 can be moved backward, thereby reducing the excessive angle change between the collecting shovel 20 and the cylinder body 11 caused by the change in the inclination angle of the collecting shovel 20 relative to the ground, and increasing the resistance when the garbage enters the cylinder body 11 from the collecting shovel 20. Thus, the shoveled garbage can easily enter the cylinder body 11 from the collecting shovel 20, which can improve the connection effect and the garbage collection effect. In addition, improving the garbage collection effect also means that the garbage will not be unable to enter the cylinder body 11 due to excessive resistance when entering the cylinder body 11. When the garbage cannot enter the cylinder body 11 for collection, the garbage may fly out of the device, thereby increasing the road safety risk. Therefore, the garbage collection device 100 according to the embodiment of the present application can also improve the safety during garbage collection.

[0040] According to the garbage collection device 100 of the embodiment of the present invention, the rear end of the collecting shovel 20 is rotatably connected to the rear side edge of the opening 101 of the cylinder body 11.

[0041] More specifically, in combination with Figure 2 , the connection position between the collecting shovel 20 and the cylinder body 11 can be that, in the horizontal projection, the connection position between the collecting shovel 20 and the cylinder body 11 is located behind the axis of the cylinder body 11; in the vertical projection, the connection position between the collecting shovel 20 and the cylinder body 11 is located below the axis of the cylinder body 11. Among them, the horizontal projection can be a projection from top to bottom, and the vertical projection can be a projection from front to back. When projecting along the up and down direction, the connection position of the collecting shovel 20 is behind the axis position. When projecting along the front and back direction, the connection position of the collecting shovel 20 is below the axis. That is to say, when the connection position between the collecting shovel 20 and the cylinder body 11 is connected within a certain area, the extension length of the collecting shovel 20 can be appropriately extended, and the angle change at the connection position between the collecting shovel 20 and the cylinder body 11 can be reduced, thereby reducing the resistance when the garbage slides from the collecting shovel 20 into the cylinder body 11, which is beneficial to improving the garbage collection effect. In combination with Figure 2 , the connection position between the collecting shovel 20 and the cylinder body 11 is a, and the connection position a can be set in the A area. When the connection position between the collecting shovel 20 and the cylinder body 11 is closer to the axis, the smaller the angle change of the collecting shovel 20 affected by the uneven ground is on the rotation change at the connection between the collecting shovel 20 and the cylinder body 11, and the smaller the resistance when the garbage enters.

[0042] In combination with Figure 2, in some embodiments of the present utility model, in the horizontal projection, the front end of the collection shovel 20 is arranged in front of the axis of the cylinder body 11, which can increase the length of the collection shovel 20 extending in the front-rear direction, thereby reducing the angle or the shoveling angle between the front end of the collection shovel 20 and the ground, and facilitating the reduction of the resistance when the garbage enters the collection shovel 20. Preferably, in the horizontal projection, the rear end of the collection shovel 20 is connected to the rear side of the cylinder body 11, and the front end of the collection shovel 20 is arranged on the front side of the cylinder body 11, which can extend the length of the collection shovel 20, thereby reducing the angle between the front end of the collection shovel 20 and the ground, as well as the angle between the rear end of the collection shovel 20 and the cylinder body 11, so as to reduce the resistance during garbage collection.

[0043] In some embodiments of the present utility model, the cylinder body 11 and the collection shovel 20 are smoothly connected, which is conducive to further reducing the resistance when the garbage enters. Specifically, the rear end of the collection shovel 20 can be configured into an arc shape, the opening 101 of the cylinder body 11 can be in an arc shape, and the rear end of the collection shovel 20 is connected to the rear side of the opening 101 of the cylinder body 11, which can construct a slideway for the convenience of the garbage to enter.

[0044] Combined with Figure 3 , the garbage collection device 100 includes a connecting rod 25. The connecting rod 25 includes a first rod body and a second rod body. The first rod body is connected to the collection shovel 20, and the second rod body is connected to the supporting wheel 23. There is an angle between the first rod body and the second rod body, which can fix the supporting wheel 23 at a predetermined height and improve the supporting effect.

[0045] Optionally, combined with Figure 1 , a plurality of reinforcing ribs 24 can be provided on the bottom wall of the collection shovel 20. The reinforcing ribs 24 protrude from the bottom wall of the collection shovel 20 to improve the structural strength of the collection shovel 20.

[0046] Furthermore, in some embodiments of the present utility model, a first baffle 21 and a second baffle 22 are respectively connected to the left and right ends of the collection shovel 20. The first baffle 21 and the second baffle 22 are respectively connected to the collection shovel 20, and the first baffle 21 and the second baffle 22 can play a shielding role on the left and right sides. Combined with Figure 3 , the first baffle 21, the second baffle 22 and the collection shovel 20 can construct an open collection cavity, which can prevent the shoveled garbage from flying out from the side, improve the garbage collection effect, and facilitate the reduction of flying stones.

[0047] Combined with Figure 2 and Figure 4, in some embodiments of the present utility model, the garbage collection device 100 further includes a driving member 30, the driving member 30 is connected between the barrel 11 and the collection shovel 20, and is adapted to drive the collection shovel 20 to rotate relative to the barrel 11; the collection shovel 20 has a first position and a second position. When the collection shovel 20 rotates to the first position, the collection shovel 20 is retracted to cover the opening 101, and when the collection shovel 20 rotates to the second position, the collection shovel 20 is unfolded to approach the ground. Thus, the collection shovel 20 can be retracted when there is no need to collect garbage, and can be unfolded when it is necessary to collect garbage or dump the collected garbage, which is beneficial to improving the functionality of the device. Specifically, when the collection device is not working or has finished working, the driving member 30 can drive the collection shovel 20 to rotate to the first position to retract the collection shovel 20, and the retracted collection shovel 20 can cover the opening 101 at the bottom of the barrel 11, thereby preventing the collected garbage from falling. When it is necessary to dump or collect garbage, the collection shovel 20 is rotated to the second position to open the opening 101 of the barrel 11, and the collection shovel 20 is close to the ground, facilitating the collection of garbage on the ground.

[0048] Specifically, in combination with Figure 2 and Figure 4 , in some embodiments of the present utility model, the driving member 30 includes a first rod portion 31, a second rod portion 32 and a third rod portion 33. The first ends of the first rod portion 31 and the second rod portion 32 are hinged, and the second ends are respectively hinged to the barrel 11. The first rod portion 31 and the second rod portion 32 and the barrel 11 form a triangular structure, which can improve the structural stability; one end of the third rod portion 33 is hinged to the first ends of the first rod portion 31 and the second rod portion 32, and the other end is hinged to the collection shovel 20. Thus, the driving member 30, the barrel 11 and the collection shovel 20 can form a linkage structure, wherein the first rod portion 31 is telescopic, and when the first rod portion 31 is telescoped, it can drive the collection shovel 20 to rotate relative to the barrel 11. More specifically, in combination with Figure 2 , the storage bin 10 further includes a support arm 14 and a connecting frame 16. The support arm 14 is connected to the barrel 11 and extends in the vertical direction, and the connecting frame 16 is connected to the barrel 11 and extends in the front-rear direction. The first rod portion 31 is hinged to the support arm 14, and the second rod portion 32 is hinged to the connecting frame 16. One end of the connecting frame 16 is connected to the barrel 11 and is in a cantilever shape. The other end of the connecting frame 16 can be used to connect the garbage collection device 100 to the vehicle head 200 or the vehicle body 300. When the vehicle moves forward, it can drive the garbage collection device 100 to shovel the garbage on the ground forward.

[0049] Optionally, the second rod portion 32 can be arc-shaped. Thus, when the first rod portion 31 is telescoped, the arc-shaped structure of the second rod portion 32 can define the movement trajectory of the collection shovel 20.

[0050] More specifically, in combination with Figure 5, in some embodiments of the present utility model, the third rod portion 33 includes a housing 331, an elastic body 332, and a limiting shaft 333. A part of the limiting shaft 333 extends into the housing 331. The elastic body 332 is disposed within the housing 331 and abuts against the limiting shaft 333 along the extending direction of the limiting shaft 333. The elastic body 332 is adapted to expand and contract along the extending direction of the limiting shaft 333. One end of the limiting shaft 333 is configured with a stepped portion. There is a cavity within the housing 331. A part of the limiting shaft 333 extends into the cavity. The elastic member is supported between the stepped portion and the inner wall of the cavity. In this way, when the limiting shaft 333 is subjected to pressure from the collection shovel 20, the elastic body 332 can be compressed to play a buffering role, thereby improving the stability of the collection shovel 20.

[0051] The elastic body 332 may include two elastic members. The two elastic members are distributed at both ends of the stepped portion of the limiting shaft 333. The housing 331 can fix the elastic body 332 and can also be used to limit the axial and radial movement and rotation of the limiting shaft 333, and only expand and contract with the change in the length of the elastic body 332. One end of the elastic body 332 is fixed within the housing 3311, and the other end is connected to the limiting shaft. Neither end can move or rotate.

[0052] Preferably, the length range of the limiting shaft 333 extending out of the housing 331 is greater than or equal to the deformation amount of the elastic body 332.

[0053] Combined with Figure 1 and Figure 2 , in some embodiments of the present utility model, the storage bin 10 includes a storage compartment door 12. The storage compartment door 12 is disposed on the cylinder body 11. The storage compartment door 12 is adapted to open and close the storage portion. When the storage compartment door 12 closes the storage portion, garbage can be stored; when it is necessary to dump the garbage, the storage compartment door 12 can be opened to expose the storage portion.

[0054] During application, the first rod portion 31 is a telescopic rod, and the second rod portion 32 is a connecting rod. One end of each of the first rod portion 31 and the second rod portion 32 is respectively hinged to the storage bin 10 and can rotate along the axis, and a triangle is formed. The other ends of the first rod portion 31 and the second rod portion 32 are hinged to one end of the third rod portion 33; the other end of the third rod portion 33 is hinged to the collection shovel 20. The change in the length of the first rod portion 31 can change the angular change of the second rod portion 32 and the angular change of the collection shovel 20. The third rod portion 33 is used to absorb road surface changes (height changes when the slope and unevenness).

[0055] Preferably, the telescopic length of the first rod portion 31 is greater than or equal to the length change of the third rod portion 33.

[0056] Specifically, in some embodiments of the present utility model, the storage compartment door 12 has a fixed end and a free end. The fixed end is hinged to the cylinder body 11. The storage bin 10 further includes a limiting member 13. One end of the limiting member 13 is connected to the cylinder body 11 and the other end is detachably connected to the free end of the storage compartment door 12. The limiting member 13 has a third position and a fourth position. When the limiting member 13 is in the third position, it is clamped with the storage compartment door 12. When the limiting member 13 is in the fourth position, it is separated from the storage compartment door 12. That is to say, the limiting member 13 is connected to the storage compartment door 12, which can support the storage compartment door 12 to maintain the storage state. When the limiting member 13 is separated from the storage compartment door 12, the storage compartment door 12 can be opened. Specifically, in combination with Figure 2 , a support shaft 15 is provided on the cylinder body 11. The support shaft 15 is inside the storage part. The support shaft 15 can be located at the axis or close to the axis. One end of the storage compartment door 12 is hinged to the support shaft 15 and the other end is clamped with the limiting member 13. In this way, the storage compartment door 12 constructs a storage space inside the storage part. The garbage entering from the opening 101 of the cylinder body 11 can enter the storage space and be supported by the storage compartment door 12. When the limiting member 13 leaves the storage compartment door 12, the storage compartment door 12 falls under the action of gravity, and the collected garbage falls as the storage compartment door 12 is opened.

[0057] Furthermore, the limiting member 13 includes a fixing part 131, a clamping part 132 and a driving rod 133. The fixing part 131 is connected between the cylinder body 11 and the end of the driving rod 133 to facilitate the movement of the driving rod 133 relative to the cylinder body 11. The driving rod 133 is telescopically connected between the fixing part 131 and the clamping part 132. The end of the clamping part 132 is provided with a card slot. The free end of the storage compartment door 12 is adapted to extend into the card slot. The driving rod 133 can drive the clamping part 132 to clamp the storage compartment door 12 or release the storage compartment door 12. The limiting member 13 may further include a support part 1321. The support part 1321 is connected between the clamping part 132 and the cylinder body 11, which can improve the stability when the clamping part 132 is clamped. The support part 1321 can be provided below the fixing part 131 and close to the storage compartment door 12. The first end of the clamping part 132 is hinged to the driving rod 133, and the second end of the clamping part 132 is hinged to the support part 1321 and clamps the storage compartment door 12. Among them, the driving rod 133, the clamping part 132 and the cylinder body 11 can construct a triangular structure, which can improve the structural stability.

[0058] The garbage collection vehicle 1000 according to the embodiment of the present utility model includes: a vehicle head 200 and the aforementioned garbage collection device 100. The garbage collection device 100 is connected to the front side of the vehicle head 200. When the vehicle travels forward, the garbage can be collected by the garbage collection device 100. By applying the aforementioned garbage collection device 100, the garbage collection effect can be improved and the operation is convenient.

[0059] When the garbage collection device 100 is applied to the garbage collection vehicle 1000, the storage bin 10 of the garbage collection device 100 does not move, and the driving member 30 only drives the collection shovel 20 to rotate. Therefore, when the vehicle travels on a road surface with a large slope, the storage bin 10 will not block the driver's line of sight, and the operator does not need to frequently adjust the garbage collection device 100 according to the change of the road surface slope. The operator only needs to deploy the collection shovel 20 at the beginning of collection, open the cylinder body 11 when dumping garbage is required, or retract the collection shovel 20 after use. That is, during the garbage collection process, the operator only needs to open and close the collection shovel 20. In the related art, during the garbage collection process, if the road surface is uneven or has a large slope, the operator needs to lift the entire garbage collection device to avoid the collision between the shovel plate and the road surface.

[0060] During actual application, in the vehicle transportation pre-preparation state, the vehicle state is that the storage compartment door 12 is closed (its state is horizontally placed), the limiting member 13 is opened to restrict, restricting the storage compartment door 12 from swinging downward to open the door along the pin shaft due to heavy objects or its own weight, and the driving member 30 drives the shovel plate slideway of the collection shovel 20 to lift upward, which can drive the collection shovel 20 to close.

[0061] When the vehicle is working, the driving member 30 drives the shovel plate slideway of the collection shovel 20 to fall downward, and the supporting wheels 23 on the collection shovel 20 support on the ground. During the vehicle driving process, the third rod portion 33 can play an elastic buffering effect, so that the collection shovel 20 can change with the change of the road surface height or slope. The supporting wheels 23 support and roll on the ground, keeping a gap between the shovel mouth of the collection shovel 20 and the ground. The collection shovel 20 constructs a U-shaped slideway, and the slideway of the collection shovel 20 gradually extends in an arc from bottom to top from front to back. Thus, the collection shovel 20 can collect large garbage / foreign objects on the road surface on the collection shovel 20, and along with the vehicle driving speed and the wind pressure of the slideway, push the large garbage / foreign objects on the slideway along the inner walls of the collection shovel 20 and the cylinder body 11 to the storage compartment door 12.

[0062] When the vehicle finishes working, the driving member 30 drives the shovel plate slideway of the collection shovel 20 to lift upward so that the collection shovel 20 closes.

[0063] When the vehicle dumps garbage, the driving member 30 drives the shovel plate slideway of the collection shovel 20 to fall downward, and the supporting wheels 23 support on the ground. Then, the restriction of the limiting member 13 is released, so that the storage compartment door 12 swings downward to open the door along the pin shaft due to heavy objects or its own weight, and the items in the storage compartment are cleaned.

[0064] After cleaning, the storage compartment door 12 is closed (its state is horizontally placed), the limiting member 13 is opened to restrict the storage compartment door 12 from swinging downward to open the door along the pin shaft due to heavy objects or its own weight. And the driving member 30 drives the shovel plate slideway of the collection shovel 20 to lift upward (the collection shovel 20 closes).
