The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0061] As Figures 1 - 16 shown, this embodiment provides a garbage collection device and an environmental cleaning vehicle. The environmental cleaning vehicle includes a vehicle body and a garbage collection device provided on the vehicle body. In this embodiment, the environmental cleaning vehicle is a sweeper, and the sweeper further includes a garbage cleaning device provided on the vehicle body. The garbage cleaning device can move along with the vehicle body and clean the garbage on the ground, and can also put the cleaned garbage into the garbage collection device for collection. It should be noted that the structure and working principle of the garbage cleaning device are prior art and will not be elaborated here. Of course, in other embodiments, the environmental cleaning vehicle can also be a garbage recycling vehicle, which is used to recycle the garbage in garbage bins such as roadside garbage bins.

[0062] As Figures 1 - 4As shown in the figure, the garbage collection device includes a garbage bin 1, a garbage bag storage member 2, a bag laying mechanism 3, a garbage detection member 4, a garbage bag closing mechanism 5, a garbage bag sealing mechanism 6, and a pushing mechanism 7. The garbage bin 1 includes a bin body 11, a bin door 12, and a door driving member 13. The bin body 11 is fixedly installed on the vehicle body. The bin body 11 includes a garbage collection cavity 111, a garbage inlet 112, and a bin opening 113. The garbage inlet 112 and the bin opening 113 are both communicated with the garbage collection cavity 111. The door driving member 13 is used to drive the bin door 12 to move so that the bin door 12 can close or open the bin opening 113. The garbage bag storage member 2 is fixedly installed at the garbage inlet 112; the garbage bag storage member 2 is used to store the garbage bag 100 and open the open end 101 of the garbage bag 100. The bag laying mechanism 3 can unfold and lay the garbage bag 100 in the garbage collection cavity 111. The garbage detection member 4 is used to detect the garbage in the garbage bag 100 to determine whether the garbage bag 100 is full. The garbage bag closing mechanism 5 includes a plurality of closing members and a closing driving assembly 52. The plurality of closing members are arranged in sequence along the circumference of the garbage inlet 112. The closing driving assembly 52 is communicatively connected with the garbage detection member 4. The closing driving assembly 52 is used to drive the plurality of closing members to move so that the plurality of closing members can clamp the garbage bag 100 for closing. The garbage bag sealing mechanism 6 includes a heating member 61. The heating member 61 is used to heat the closing part of the garbage bag 100 to heat-seal and fuse the garbage bag 100. The pushing mechanism 7 includes a pushing member 71 and a pushing driving member 72. The pushing driving member 72 is used to drive the pushing member 71 to move to push the heat-sealed garbage bag 100 out of the garbage bin 1 from the bin opening 113.

[0063] In the garbage collection device of this embodiment, after the garbage detection member 4 detects that the garbage bag 100 is full, the closing driving assembly 52 can be used to drive the plurality of closing members to move so that the plurality of closing members can clamp the garbage bag 100 for closing. Then, the garbage bag 100 is heat-sealed and fused by the garbage bag sealing mechanism 6, that is, the automatic garbage packing is completed. Then, the door driving member 13 is used to drive the bin door 12 to open, and then the pushing driving member 72 is used to drive the pushing member 71 to push the sealed garbage bag 100 out of the garbage bin 1 from the bin opening 113; at the same time, the garbage bag 100 is stored by the garbage bag storage member 2, and the garbage bag 100 is automatically laid in the garbage bin 1 by the bag laying mechanism 3. The degree of automation is high, and the efficiency of garbage collection work is improved.

[0064] It should be noted that after the heating member 61 heats the closing part of the garbage bag 100 to heat-seal and fuse the garbage bag 100, the garbage bag 100 forms two closed fusing ends. One fusing end is the bag mouth of the garbage bag 100 filled with garbage, thereby realizing the automatic packing and sealing of the garbage; the other fusing end is the bottom end of the next garbage bag 100, which closes the bottom end of the next garbage bag 100 for continuously containing garbage.

[0065] Optionally, the garbage detection member 4 is a ranging sensor for detecting the height of the garbage in the garbage bag 100. When the height measured by the garbage detection member 4 in the garbage bag 100 reaches a preset height, it indicates that the garbage bag 100 is full, and then the closing drive assembly 52 can be used to drive a plurality of closing members to move for closing. Exemplarily, the ranging sensor uses a single-angle ultrasonic ranging sensor, and the measurement accuracy is higher.

[0066] Optionally, the bag laying mechanism 3 includes a negative pressure assembly for generating negative pressure in the garbage receiving cavity 111, so that the garbage bag 100 can be attached to the inner wall of the garbage receiving cavity 111 to achieve automatic bag laying.

[0067] Exemplarily, the negative pressure assembly uses a turbine fan to extract the air in the garbage receiving cavity 111 to generate negative pressure in the garbage receiving cavity 111. The structure is simple and the cost is low. Preferably, there are two turbine fans, and the two turbine fans are respectively arranged on opposite sides of the box body 11, so that the negative pressure in the garbage receiving cavity 111 is more uniform, ensuring that the garbage bag 100 is laid flat. Of course, the turbine fan can also be set to one, three, four, or even more, which is not limited here.

[0068] Optionally, a seal is provided between the box body 11 and the box door 12 to improve the sealing performance of the garbage receiving cavity 111 through the seal, which is beneficial to improving the working efficiency of the negative pressure assembly. Exemplarily, the seal is a sealing strip, and the sealing strip surrounds the periphery of the box door 12.

[0069] As Figures 5 - 7 shown, optionally, the garbage bag storage member 2 includes a bag storage box 21. The bag storage box 21 has an annular structure and is correspondingly arranged with the garbage inlet 112. It can be understood that the annular bag storage box 21 is provided with a box center hole, and the box center hole is coaxially arranged with the garbage inlet 112. Further, the bag storage box 21 includes a bag storage cavity 211 and a garbage bag inlet and outlet 212 communicating with the bag storage cavity 211. The open end 101 of the garbage bag 100 passes through the garbage bag inlet and outlet 212 and is stacked in the bag storage cavity 211. Then, after the filled garbage bag 100 is packed, the bag laying mechanism 3 can extract a part of the garbage bag 100 from the garbage bag inlet and outlet 212 to form the next garbage bag 100 and lay it in the garbage receiving cavity 111. At the same time, the garbage bags 100 are stacked layer by layer in the bag storage cavity 211 and stored neatly, which is convenient for the garbage bag 100 to be smoothly extracted.

[0070] Optionally, the bag storage box 21 is provided with a storage handle 213, which is convenient for taking and assembling the bag storage box 21 by holding the storage handle 213.

[0071] Optionally, the garbage inlet 112 is provided at the top of the box body 11, which facilitates the input of garbage into the box body 11. Further, the top of the bag storage box 21 is open to form a garbage bag inlet / outlet 212, so that the area of the garbage bag inlet / outlet 212 is relatively large, facilitating the extraction of the garbage bag 100 from the bag storage box 21. Further, the annular bag storage box 21 includes an inner side wall 214 and an outer side wall 215, and the top surface of the inner side wall 214 is lower than the top surface of the outer side wall 215, which is beneficial to further improve the smoothness of extracting the garbage bag 100 from the bag storage box 21.

[0072] As Figure 10 shown, optionally, the plurality of closing members include two first closing members 51a, a second closing member 51b, and a third closing member. The two first closing members 51a are arranged opposite to each other in a first direction; the third closing member is fixedly provided on one side of the garbage inlet 112, and the second closing member 51b is arranged opposite to the third closing member in a second direction; the second direction is perpendicular to the first direction.

[0073] The closing driving assembly 52 includes a closing transmission unit 521 and a closing driving member 522. The closing transmission unit 521 includes four lead screws sequentially arranged along the circumferential direction of the garbage bag 100 and four commutators 5212. Adjacent two lead screws are connected by a commutator 5212. The closing driving member 522 is used to drive one of the lead screws to rotate, so as to drive the remaining lead screws to rotate; both ends of the first closing member 51a are respectively threadedly connected to two of the lead screws, so that the two first closing members 51a can move relatively or towards each other in the first direction; both ends of the second closing member 51b are respectively threadedly connected to the other two lead screws, so that the second closing member 51b can move towards or away from the third closing member in the second direction.

[0074] The closing transmission unit 521 is formed by sequentially connecting four lead screws end to end through four commutators 5212. Thus, by driving one of the lead screws to rotate by a closing driving member 522, the remaining lead screws can be driven to rotate synchronously. The structure is simple, the cost is low, and the energy consumption is low; the closing transmission unit 521 can drive the two first closing members 51a to move relatively in the first direction, and can synchronously drive the second closing member 51b to move towards the third closing member in the second direction, finally enabling the two first closing members 51a, the second closing member 51b, and the third closing member to clamp the garbage bag 100, capable of automatically closing the opening of the garbage bag 100 in the garbage bin 1, with good closing effect, and not damaging the garbage bag 100, preventing secondary pollution.

[0075] Exemplarily, the commutator 5212 is a bevel gear commutator; the closing driving member 522 is a stepping motor.

[0076] Optionally, the four lead screws include a driving lead screw 5211a. The driving lead screw 5211a includes two lead screw bodies 5211a1, and the two lead screw bodies 5211a1 are respectively connected to two ends of the driving shaft of the closing driving member 522. One end of the lead screw body 5211a1 away from the closing driving member 522 is connected to the corresponding commutator 5212. Specifically, the two lead screw bodies 5211a1 are respectively threadedly connected to the two first closing members 51a. Such a setting is conducive to improving the force uniformity of the four lead screws and ensuring more stable transmission.

[0077] Further, the thread directions of the two lead screw bodies 5211a1 are opposite, so that the two first closing members 51a can be respectively driven by the two lead screw bodies 5211a1 to move relatively or towards each other in the first direction.

[0078] Further, the four lead screws further include two first driven lead screws 5211b and a second driven lead screw 5211c. The second driven lead screw 5211c and the driving lead screw 5211a are respectively located at two ends of the first closing member 51a, and the two first driven lead screws 5211b are respectively located at two ends of the driving lead screw 5211a and the second driven lead screw 5211c. The second driven lead screw 5211c is provided with two second driven threads respectively threadedly connected to the two first closing members 51a, and the thread directions of the two second driven threads are opposite, so that the two first closing members 51a can be respectively driven by the second driven lead screw 5211c to move relatively or towards each other in the first direction.

[0079] Optionally, the second closing member 51b is provided with sliding grooves 51b1 arranged in one-to-one correspondence with the two first closing members 51a, and the first closing member 51a is slidably arranged in the corresponding sliding groove 51b1 along the first direction. The second closing member 51b further includes a closing clamping portion 51b2, and the closing clamping portion 51b2 is located between the two sliding grooves 51b1. The closing clamping portion 51b2 can press the garbage bag 100 against the third closing member. Such a setting prevents the first closing member 51a and the second closing member 51b from interfering with each other, and is also conducive to ensuring the stability of the clamping of the garbage bag 100 by the two first closing members 51a, the second closing member 51b and the third closing member.

[0080] Optionally, a non-slip structure is provided on the side of the closing clamping portion 51b2 facing the third closing member, and the non-slip structure prevents the garbage bag 100 from sliding, ensuring the closing and heat-sealing effects. Exemplarily, the non-slip structure is a plurality of protrusions arranged on the side of the closing clamping portion 51b2 facing the third closing member. Of course, the non-slip structure can also be an anti-slip pad fixed on the side of the closing clamping portion 51b2 facing the third closing member. The non-slip structure can also adopt other structures, which are not limited herein.

[0081] Optionally, on one side of the two first closing parts 51a opposite to each other along the first direction, there are first closing surfaces 51a1 provided, and at both ends of the first closing surface 51a1 along the third direction, there are first round chamfers 51a2; the third direction, the second direction and the first direction are perpendicular to each other in pairs; further, on the side of the second closing part 51b facing the third closing part, there is a second closing surface 51b3 provided, and at both ends of the second closing surface 51b3 along the third direction, there are second round chamfers 51b4. With such a setting, it is possible to avoid damage to the garbage bag 100 caused by the first closing part 51a and the second closing part 51b.

[0082] As Figure 9 shown, optionally, the garbage bag closing mechanism 5 further includes a closing housing 53. The closing housing 53 is of an annular structure and is correspondingly arranged with the garbage inlet 112. It can be understood that the closing housing 53 of the annular structure is provided with a central hole of the closing housing, and the central hole of the closing housing is coaxially arranged with the garbage inlet 112. Further, the lead screw and the commutator 5212 are both arranged inside the closing housing 53, which is beneficial to improving the aesthetics of the garbage bag closing mechanism 5 and can protect the lead screw and the commutator 5212.

[0083] Further, on the inner side of the closing housing 53 of the annular structure, there is an avoidance opening 531 for avoiding the first closing part 51a and the second closing part 51b, so as not to interfere with the movement of the first closing part 51a and the second closing part 51b.

[0084] It should be noted that through the closing housing 53, the garbage bag closing mechanism 5 can be formed into a whole, which is convenient for disassembling and assembling the garbage bag closing mechanism 5.

[0085] Optionally, the closing housing 53 is provided with a closing handle 532, and it is convenient to take and assemble the garbage bag closing mechanism 5 by holding the closing handle 532.

[0086] Optionally, the closing housing 53 is provided with a closing installation opening 533 and a closing cover body 534 for closing the closing installation opening 533. The closing cover body 534 is detachably connected to the closing housing 53. By opening the closing cover body 534, it is convenient to assemble and repair the lead screw and the commutator 5212 inside the closing housing 53.

[0087] In this embodiment, the heating element 61 is an electric heating element, such as an electric heating wire. Exemplarily, the diameter of the electric heating wire is 1 mm, which can not only meet the heat sealing requirements, but also will not excessively increase the energy consumption. Of course, the diameter of the electric heating wire can also be set to other values, which is not limited herein.

[0088] It should be noted that the garbage bin 1 of the existing environmental cleaning vehicle is usually made of metal material, and the electric heating element is likely to cause electric leakage or short circuit problems with the garbage bin 1, thereby affecting the normal operation of the environmental cleaning vehicle.

[0089] To solve the above problems, as Figures 11 - 14 shown, the garbage bag sealing mechanism 6 further includes a sealing fixing member 62, a sealing mounting member 63, a first sealing locking member 64, a first insulating member 65 and a second insulating member 66. The electric heating member is fixedly arranged on the sealing mounting member 63; the first sealing locking member 64 is used to lock or unlock the sealing mounting member 63 and the sealing fixing member 62; the first insulating member 65 is used to insulate between the sealing mounting member 63 and the sealing fixing member 62; the second insulating member 66 is used to insulate between the first sealing locking member 64 and the sealing mounting member 63. In this embodiment, both the sealing fixing member 62 and the sealing mounting member 63 are made of metal materials, which are strong and durable.

[0090] Specifically, the sealing fixing member 62 is fixedly arranged on the third closing member, so that the first closing member 51a and the second closing member 51b can press the garbage bag 100 against the electric heating member. This not only enables the electric heating member to heat the closing part of the garbage bag 100 to heat-seal and fuse the garbage bag 100, but also improves the sealing effect and ensures the sealing performance of the garbage bag 100 after sealing.

[0091] The electric heating member is fixedly arranged on the sealing mounting member 63, and the sealing mounting member 63 can play a role in dissipating heat for the electric heating member; the sealing mounting member 63 is locked with the sealing fixing member 62 through the first sealing locking member 64, so that the garbage bag sealing mechanism 6 forms a whole, which is convenient for assembly. And through the first insulating member 65, insulation is formed between the sealing mounting member 63 and the sealing fixing member 62, and through the second insulating member 66, insulation is formed between the first sealing locking member 64 and the sealing mounting member 63. The insulation performance is good, and there will be no problems of electric leakage or short circuit.

[0092] Exemplarily, the sealing mounting member 63 is made of copper metal, and the heat dissipation effect is better.

[0093] Optionally, the first insulating member 65 includes an insulating gasket, and the insulating gasket is clamped between the sealing mounting member 63 and the sealing fixing member 62, and the insulating gasket is attached to the sealing fixing member 62.

[0094] In this embodiment, the insulating gasket is a Teflon tape, which not only has good insulation effect, but also is high-temperature resistant, corrosion-resistant and has a long service life.

[0095] In this embodiment, the first sealing locking member 64 includes a first sealing bolt 641 and a first sealing nut 642, the sealing mounting member 63 is provided with a first sealing hole, the sealing fixing member 62 is provided with a second sealing hole, the first sealing nut 642 is provided on the side of the sealing fixing member 62 away from the sealing mounting member 63, and one end of the first sealing bolt 641 passes through the first sealing hole and the second sealing hole in sequence and is threadedly connected with the first sealing nut 642. Of course, in other embodiments, the first sealing nut 642 may not be provided, and the second sealing hole may be provided as a threaded hole, so that one end of the first sealing bolt 641 passes through the first sealing hole and is threadedly connected with the second sealing hole, and the fixed connection between the first sealing bolt 641 and the sealing fixing member 62 can also be achieved.

[0096] Furthermore, the second insulating member 66 includes an insulating washer 661 and an insulating washer 662. The insulating washer 661 is sleeved on the outside of the first sealing bolt 641 and is located in the first sealing hole. The insulating washer 662 is sleeved on the outside of the first sealing bolt 641 and is fixedly connected to the insulating washer 661. The outer diameter of the insulating washer 662 is greater than the inner diameter of the first sealing hole. The two ends of the insulating washer 662 along the axial direction of the first sealing bolt 641 are respectively in contact with the first sealing bolt 641 and the sealing mounting member 63. In other words, the second insulating member 66 is a stepped insulating washer, which can prevent the rod of the first sealing bolt 641 from contacting the inner surface of the first sealing hole, and can also prevent the head of the first sealing bolt 641 from contacting the outer surface of the sealing mounting member 63, thereby ensuring insulation.

[0097] Optionally, the garbage bag sealing mechanism 6 further includes a second sealing locking member and a third insulating member, wherein the second sealing locking member is used to lock or unlock the electric heating member and the sealing mounting member 63; and the third insulating member is used to insulate the second sealing locking member from the sealing mounting member 63. The electric heating member is fixedly mounted on the sealing mounting member 63 through the second sealing locking member, which is convenient for disassembly and assembly to replace the electric heating member, and the insulation is ensured by the third insulating member, so that there will be no leakage or short circuit problems.

[0098] In this embodiment, the second sealing locking member includes a second sealing bolt 671, and the third insulating member includes an insulating washer 3 681. Two second sealing bolts 671 and two insulating washers 3 681 are provided, and the second sealing bolts 671 and the insulating washers 3 681 are provided one by one.

[0100] Optionally, the sealing mount 63 is provided with a heat dissipation structure, and the heat dissipation structure can improve the heat dissipation effect of the sealing mount 63.

[0101] In this embodiment, the sealing mount 63 includes a first surface 632 and a plurality of second surfaces 633. The electric heating element is fixed on the first surface 632; the plurality of second surfaces 633 are all connected to the first surface 632, and the plurality of second surfaces 633 are arranged in sequence along the circumferential direction of the first surface 632. The angle between the second surface 633 and the first surface 632 is an obtuse angle. In other words, the second surface 633 is inclined, which increases the contact area between the sealing mount 63 and the air, is beneficial to improving the heat dissipation effect, and does not interfere with the contact between the electric heating element and the garbage bag 100 for heat sealing.

[0102] It can be understood that in this embodiment, the second surface 633 is used as the heat dissipation structure. Of course, in other embodiments, the heat dissipation structure can also be set in other forms, which is not limited herein.

[0103] Optionally, the first surface 632 and the second sealing bolt 671 are respectively located on both sides of the sealing mount 63, thereby avoiding interference between the second sealing bolt 671 and the garbage bag 100 and ensuring the heat sealing effect.

[0104] Optionally, there are two cabinet doors 12, and the two cabinet doors 12 are respectively arranged on opposite sides of the cabinet opening 113; there are two door driving members 13, and the cabinet doors 12 and the door driving members 13 are arranged in one-to-one correspondence. Thus, when the cabinet doors 12 are opened, the occupied space is relatively small, which is beneficial to improving the versatility of the garbage storage device.

[0105] Optionally, the cabinet door 12 is rotatably arranged on the cabinet body 11 through a hinge. The inner side of the cabinet door 12 is provided with a door mounting groove 121. One end of the door driving member 13 is hinged in the door mounting groove 121, and the other end is hinged to the cabinet body 11. With this arrangement, when the cabinet door 12 is closed, the door driving member 13 can be embedded in the door mounting groove 121. On the one hand, it avoids the door driving member 13 being exposed in the garbage storage cavity 111 and does not occupy the space of the garbage storage cavity 111, which is beneficial to increasing the capacity of the garbage storage cavity 111. On the other hand, it avoids the door driving member 13 being exposed outside the cabinet body 11, improves the aesthetics, and is also beneficial to protecting the door driving member 13.

[0106] Exemplarily, the door driving member 13 is an electric push rod.

[0107] It should be noted that, asFigure 4 As shown, by opening the box door 12, the garbage bag storage member 2, the garbage bag closing mechanism 5, and the garbage bag sealing mechanism 6 can be directly taken out, which is convenient for maintenance.

[0108] As Figures 15 - 16 shown, optionally, the box opening 113 is provided on one side of the box body 11, and the pushing member 71 is provided at the bottom inside the box body 11. One end of the pushing member 71 is hinged to the box body 11 and located at the box opening 113, and the other end is connected to the pushing driving member 72, thereby facilitating the smooth pushing out of the packed garbage bag 100 from the garbage bin 1.

[0109] In this embodiment, the driving end of the pushing driving member 72 is hinged to the pushing member 71, and the mounting end of the pushing driving member 72 is hinged to the box body 11. Further, there are two pushing driving members 72, and the two pushing driving members 72 are respectively provided at both ends of the pushing member 71, which is beneficial to ensuring the stable lifting of the pushing member 71.
