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

[0055] As Figure 1 - 16As shown in the figure, 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 to clean the garbage on the ground, and can also put the cleaned garbage into the garbage collection device for storage. 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 collection vehicle, which is used to collect the garbage in trash cans such as roadside trash cans.

[0056] As Figure 1 - 4 shown, 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 box body 11, a box door 12 and a door driving member 13. The box body 11 is fixed on the vehicle body. The box body 11 includes a garbage storage cavity 111, a garbage inlet 112 and a box opening 113. The garbage inlet 112 and the box opening 113 are both communicated with the garbage storage cavity 111. The door driving member 13 is used to drive the box door 12 to move so that the box door 12 can close or open the box opening 113. The garbage bag storage member 2 is fixed at the garbage inlet 112; the garbage bag storage member 2 is used to store the garbage bag 100 and make the open end 101 of the garbage bag 100 open. The bag laying mechanism 3 can unfold and lay the garbage bag 100 in the garbage storage cavity 111. The garbage detection member 4 is used to detect the garbage in the garbage bag 100 to judge 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 in communication connection 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 melt 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 box opening 113.

[0057] In the garbage collection device of this embodiment, when the garbage detection member 4 detects that the garbage bag 100 is full, the closing drive assembly 52 can drive a 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 sealing mechanism 6 heat-seals and fuses the garbage bag 100, that is, the automatic garbage packing is completed. Then, the door drive member 13 drives the door 12 to open, and then the pushing drive member 72 drives 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 storage member 2 stores the garbage bag 100, and the bag-laying mechanism 3 automatically lays the garbage bag 100 in the garbage bin 1, with a high degree of automation and improved garbage collection work efficiency.

[0058] It should be noted that after heating the closing part of the garbage bag 100 by the heating member 61 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, thus 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.

[0059] Optionally, the garbage detection member 4 is a distance measuring sensor for detecting the height of the garbage in the garbage bag 100. When the garbage detection member 4 measures that the height in the garbage bag 100 reaches the preset height, it indicates that the garbage bag 100 is full, and then the closing drive assembly 52 can be made to drive a plurality of closing members to move for closing. Exemplarily, the distance measuring sensor adopts a single-angle ultrasonic distance measuring sensor, with higher measurement accuracy.

[0060] Optionally, the bag-laying mechanism 3 includes a negative pressure assembly. The negative pressure assembly is used to make the garbage storage cavity 111 generate negative pressure, so that the garbage bag 100 can adhere to the inner wall of the garbage storage cavity 111 to realize automatic bag laying.

[0061] Exemplarily, the negative pressure assembly adopts a turbine fan. The turbine fan extracts the air in the garbage storage cavity 111 to make the garbage storage cavity 111 generate negative pressure. 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 storage 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.

[0062] Optionally, a sealing member is provided between the box body 11 and the door 12. The sealing member improves the sealing performance of the garbage storage cavity 111, which is beneficial to improving the working efficiency of the negative pressure assembly. Exemplarily, the sealing member is a sealing strip, and the sealing strip surrounds the periphery of the door 12.

[0063] Such as Figure 5 - 7As 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 bag storage box 21 with an annular structure 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 / outlet 212 communicating with the bag storage cavity 211. The open end 101 of the garbage bag 100 passes through the garbage bag inlet / outlet 212 and is stacked in the bag storage cavity 211. Then, after the garbage bag 100 filled with garbage is packed, the garbage bag 100 can be partially drawn out from the garbage bag inlet / outlet 212 by the bag laying mechanism 3 to form the next garbage bag 100 and laid in the garbage storage 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 bags 100 to be smoothly drawn out.

[0064] Optionally, the bag storage box 21 is provided with a storage handle 213, which facilitates the taking and assembling of the bag storage box 21 by holding the storage handle 213.

[0065] Optionally, the garbage inlet 112 is arranged at the top of the box body 11, which is convenient for putting garbage into the box body 11. Further, the top of the bag storage box 21 is open to form the garbage bag inlet / outlet 212, so that the area of the garbage bag inlet / outlet 212 is relatively large, which is convenient for drawing the garbage bag 100 out of the bag storage box 21. Further, the annular bag storage box 21 includes an inner side wall 214 and an outer side wall 215. 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 drawing the garbage bag 100 out of the bag storage box 21.

[0066] 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 the first direction; the third closing member is fixedly arranged on one side of the garbage inlet 112, and the second closing member 51b is arranged opposite to the third closing member in the second direction; the second direction is perpendicular to the first direction.

[0067] The closing drive assembly 52 includes a closing transmission unit 521 and a closing drive member 522. The closing transmission unit 521 includes four lead screws arranged in sequence along the circumferential direction of the garbage bag 100 and four commutators 5212. Adjacent two lead screws are connected by the commutator 5212. The closing drive member 522 is used to drive one of the lead screws to rotate to drive the remaining lead screws to rotate; both ends of the first closing member 51a are respectively threadedly connected with 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 with 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.

[0068] The closing transmission unit 521 is formed by four screw rods connected end to end in sequence through four commutators 5212, and then one of the screw rods can be driven to rotate by a closing drive member 522, so as to drive the other screw rods 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 relative to each other along the first direction, and can synchronously drive the second closing member 51b to move along the second direction toward the third closing member, so that the two first closing members 51a, the second closing member 51b and the third closing member finally clamp the garbage bag 100, and can automatically close the garbage bag 100 in the garbage bin 1, with good closing effect, and will not damage the garbage bag 100, thereby preventing secondary pollution.

[0069] Exemplarily, the commutator 5212 is a bevel gear commutator; and the closing drive member 522 is a stepping motor.

[0070] Optionally, the four screw rods include an active screw rod 5211a, which includes two screw rod bodies 5211a1, which are respectively connected to the two ends of the drive shaft of the closing drive member 522, and one end of the screw rod body 5211a1 away from the closing drive member 522 is connected to the corresponding commutator 5212; specifically, the two screw rod bodies 5211a1 are respectively threadedly connected to the two first closing members 51a. Such an arrangement is conducive to improving the force uniformity of the four screw rods and ensuring more stable transmission.

[0071] Furthermore, the threads of the two screw rod bodies 5211a1 have opposite rotation directions, and thus the two first closing members 51a can be driven by the two screw rod bodies 5211a1 to move relative to or toward each other along the first direction.

[0072] Furthermore, the four screw rods also include two first driven screw rods 5211b and a second driven screw rod 5211c, the second driven screw rod 5211c and the active screw rod 5211a are respectively located at two ends of the first closing member 51a, and the two first driven screw rods 5211b are respectively located at two ends of the active screw rod 5211a and the second driven screw rod 5211c. The second driven screw rod 5211c is provided with two second driven threads respectively threadedly connected to the two first closing members 51a, and the two second driven threads have opposite rotation directions, so that the two first closing members 51a can be driven by the second driven screw rod 5211c to move relative to or toward each other along the first direction.

[0073] Optionally, the second closing member 51b is provided with sliding grooves 51b1 that are arranged in one-to-one correspondence with the two first closing members 51a, and the first closing members 51a are slidably arranged in the corresponding sliding grooves 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, and the closing clamping portion 51b2 can press the garbage bag 100 against the third closing member. With such an arrangement, the first closing members 51a and the second closing member 51b will not interfere with each other, and it is also beneficial to ensure 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.

[0074] Optionally, an anti-slip structure is provided on the side of the closing clamping portion 51b2 facing the third closing member, and the anti-slip structure prevents the garbage bag 100 from sliding, ensuring the closing and heat-sealing effects. Exemplarily, the anti-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 anti-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 anti-slip structure can also adopt other structures, which are not limited herein.

[0075] Optionally, first closing surfaces 51a1 are provided on the opposite sides of the two first closing members 51a along the first direction, and first circular chamfers 51a2 are provided at both ends of the first closing surfaces 51a1 along the third direction; the third direction, the second direction and the first direction are perpendicular to each other in pairs; further, a second closing surface 51b3 is provided on the side of the second closing member 51b facing the third closing member, and second circular chamfers 51b4 are provided at both ends of the second closing surface 51b3 along the third direction. With such an arrangement, damage to the garbage bag 100 caused by the first closing member 51a and the second closing member 51b can be avoided.

[0076] As Figure 9 shown, optionally, the garbage bag closing mechanism 5 further includes a closing housing 53, and the closing housing 53 is of an annular structure and is arranged corresponding to the garbage inlet 112. It can be understood that the annular closing housing 53 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.

[0077] Further, an avoidance opening 531 for avoiding the first closing member 51a and the second closing member 51b is provided on the inner side of the annular closing housing 53, so as not to interfere with the movement of the first closing member 51a and the second closing member 51b.

[0078] 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.

[0079] Optionally, the closing shell 53 is provided with a closing handle 532, which facilitates the taking and assembling of the garbage bag closing mechanism 5 by holding the closing handle 532.

[0080] Optionally, the closing shell 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 shell 53. By opening the closing cover body 534, it is convenient to assemble and overhaul the lead screw and the commutator 5212 in the closing shell 53.

[0081] 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 requirement 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.

[0082] 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, thus affecting the normal operation of the environmental cleaning vehicle.

[0083] To solve the above problems, as Figure 11 - 14 shown, the garbage bag sealing mechanism 6 further includes a sealing fixing member 62, a sealing installation member 63, a first sealing locking member 64, a first insulating member 65 and a second insulating member 66. The electric heating element is fixedly arranged on the sealing installation member 63; the first sealing locking member 64 is used to lock or unlock the sealing installation member 63 with the sealing fixing member 62; the first insulating member 65 is used to form insulation between the sealing installation member 63 and the sealing fixing member 62; the second insulating member 66 is used to form insulation between the first sealing locking member 64 and the sealing installation member 63. In this embodiment, both the sealing fixing member 62 and the sealing installation member 63 are made of metal material, which are strong and durable.

[0084] 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 element. This not only enables the electric heating element to heat the closing part of the garbage bag 100 to heat - seal and fuse the garbage bag 100, but also can improve the sealing effect and ensure the sealing property of the garbage bag 100 after sealing.

[0085] The electric heating element is fixedly arranged on the sealing installation member 63, and the sealing installation member 63 can play a role in dissipating heat for the electric heating element; the sealing installation 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. The first insulating member 65 forms insulation between the sealing installation member 63 and the sealing fixing member 62, and the second insulating member 66 forms insulation between the first sealing locking member 64 and the sealing installation member 63, with good insulation performance and no electric leakage or short - circuit problems.

[0086] Exemplarily, the sealing mounting member 63 is made of metal copper, which has a better heat dissipation effect.

[0087] Optionally, the first insulating member 65 includes an insulating gasket, which is sandwiched between the sealing mounting member 63 and the sealing fixing member 62, and the insulating gasket is attached to the sealing fixing member 62. With such a configuration, on the one hand, the insulating gasket can be used for insulation and heat insulation, and on the other hand, the installation stability of the insulating gasket is ensured, and it is not easy to fall off or shift, and it is also easy to replace.

[0088] In this embodiment, the insulating gasket is Teflon tape, which not only has good insulation effect, but also is resistant to high temperature and corrosion and has a long service life.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] In this embodiment, the second sealing and locking member includes a second sealing bolt 671, and the third insulating member includes a third insulating washer 681. There are two second sealing bolts 671 and two third insulating washers 681, and the second sealing bolts 671 and the third insulating washers 681 are arranged in one-to-one correspondence. The two second sealing bolts 671 are respectively arranged at both ends of the heating wire. The heating wire is clamped between the head of the second sealing bolt 671 and the third insulating washer 681, and the other end of the second sealing bolt 671 passes through the third insulating washer 681 and is threadedly connected to the sealing installation member 63.

[0093] Optionally, the sealing installation member 63 is provided with a sealing installation groove 631. One side of the electric heating member can be in contact with the garbage bag 100, and the other side of the electric heating member is embedded in the sealing installation groove 631. Thus, the sealing installation groove 631 can limit the electric heating member to prevent it from shifting, and further ensure the heat sealing effect.

[0094] Optionally, the sealing installation member 63 is provided with a heat dissipation structure, and the heat dissipation structure can improve the heat dissipation effect of the sealing installation member 63.

[0095] In this embodiment, the sealing installation member 63 includes a first surface 632 and a plurality of second surfaces 633. The electric heating member 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 sequentially arranged 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 is equivalent to increasing the contact area between the sealing installation member 63 and the air, facilitating the improvement of the heat dissipation effect, and will not interfere with the contact between the electric heating member and the garbage bag 100 for heat sealing.

[0096] 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.

[0097] Optionally, the first surface 632 and the second sealing bolt 671 are respectively located on both sides of the sealing installation member 63, so as to avoid interference between the second sealing bolt 671 and the garbage bag 100 and ensure the heat sealing effect.

[0098] 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, so that the space occupied when the cabinet doors 12 are opened is smaller, which is beneficial to improving the versatility of the garbage storage device.

[0099] Optionally, the box door 12 is rotatably arranged on the box body 11 through a hinge. A door mounting groove 121 is arranged on the inner side of the box door 12. One end of the door driving member 13 is hinged in the door mounting groove 121, and the other end is hinged to the box body 11. With such an arrangement, when the box 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 receiving cavity 111, does not occupy the space of the garbage receiving cavity 111, is beneficial to increasing the capacity of the garbage receiving cavity 111, and on the other hand, it avoids the door driving member 13 being exposed outside the box body 11, improves the aesthetics, and is also beneficial to protecting the door driving member 13.

[0100] Exemplarily, the door driving member 13 is an electric push rod.

[0101] It should be noted that as Figure 4 shown, by opening the box door 12, the garbage bag receiving 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.

[0102] As Figure 15 - 16 shown, optionally, the box opening 113 is arranged on one side of the box body 11, and the pushing member 71 is arranged at the bottom inside the box body 11. One end of the pushing member 71 is hinged to the box body 11 and is 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 packaged garbage bag 100 from the garbage bin 1.

[0103] 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 arranged at both ends of the pushing member 71, which is beneficial to ensuring the stable lifting of the pushing member 71. Exemplarily, the pushing driving member 72 is an electric push rod.

[0104] Optionally, the pushing member 71 includes a bottom plate 711 and a side plate 712. One end of the bottom plate 711 is located at the box opening 113 and is hinged to the box body 11 through a hinge; one end of the side plate 712 is fixedly connected to the other end of the bottom plate 711, and the other end of the side plate 712 extends obliquely upward and abuts against the side wall of the box body 11, so that the pushing driving member 72 only needs to drive the pushing member 71 to lift a small height to push the garbage bag 100 out of the box opening 113, and the operation is more convenient.
