Therefore, it is necessary to accurately dock the garbage bin of the garbage transfer truck with the compression box of the garbage compressor during the operation.

[0003] In this regard, Chinese invention patent CN106742993A discloses a docking and locking device for a garbage compactor and a garbage bin, which drives the support member to rotate and lift the garbage bin to a suitable height through a lifting cylinder, and the support member simultaneously drives the connecting member to rotate to a horizontal state, so that the hook on the connecting member locks the garbage bin, thereby achieving docking and locking of the garbage bin and the compactor. However, since the parking position of the garbage transfer vehicle may deviate due to different operations of the driver, that is, the distance between the garbage bin and the garbage compactor is different, a large gap needs to be reserved between the locking hook and the crossbeam of the vehicle box, so there will also be a large gap between the garbage bin and the garbage compactor, which cannot be completely sealed, so that in the process of pushing and compacting the garbage blocks, more sewage and residue will flow out from the gap, seriously polluting the environment.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0034] Figures 1 to 6 The garbage transfer station and its garbage bin docking and locking device provided by an embodiment of the present invention are jointly shown, wherein the garbage bin docking and locking device is used to dock the garbage bin to the compression box of the garbage compressor to achieve a locking seal between the garbage bin and the garbage compressor. The structure is simple and compact and the locking effect is good, which effectively avoids the problem of sewage and residue leakage due to gaps in the docking structure, and has low requirements on ground strength and strong applicability.

[0035] like Figure 2 As shown, the garbage bin docking locking device 1 includes a lifting mechanism 11 and a translation mechanism 12, a support seat 13 connected to the lifting mechanism 11 and a locking hook 14 connected to the translation mechanism 12, and the support seat 13 and the locking hook 14 are movably connected.

[0036] Please combine Figures 3 to 5 The lock hook 14 is provided with a first slide groove 141, and the first slide groove 141 is extended along the locking direction of the lock hook 14. The support seat 13 is provided with a first connecting pin 131, and the first connecting pin 131 is inserted into the first slide groove 141 and is used to slide relative to the first slide groove 141, so that the lock hook 14 can rotate and translate relative to the support seat 13 through the cooperation of the first connecting pin 131 and the first slide groove 141.

[0037] Specifically, the lifting mechanism 11 is used to be installed on the ground and drive the support seat 13 to rotate, so that the garbage bin 31 above the support seat 13 is lifted up by the rotation of the support seat 13, and the locking hook 14 is driven to rotate synchronously through the cooperation of the first connecting pin 131 and the first sliding groove 141, so as to drive the locking hook 14 to rotate to a horizontal state. The translation mechanism 12 is used to be installed on the garbage compactor 2 and drive the locking hook 14 to translate relative to the support seat 13, so that when the support seat 13 lifts the garbage bin 31 to a preset height, the locking hook 14 drives the garbage bin 31 to move in a direction toward the garbage compactor 2, and then the garbage bin 31 is docked and locked to the compression box 21 of the garbage compactor 2.

[0038] The garbage bin docking locking device 1 is provided with a first connecting pin 131 and a first slide groove 141 between the support seat 13 and the locking hook 14, so that when the lifting mechanism 1 drives the support seat 13 to rotate and lift up the garbage bin 31, the locking hook 14 can be driven to rotate synchronously through the cooperation of the first connecting pin 131 and the first slide groove 141, and the locking hook 14 is driven to a horizontal state, and the locking hook 14 can slide along the first slide groove 141 under the drive of the translation mechanism 12, so as to hook the garbage bin 31 to the compression box 21 of the garbage compressor 2, and realize the docking and locking operation of the garbage bin 31. The coordinated cooperation of the first connecting pin 131 and the first slide groove 141 enables the locking hook 14 to rotate and translate respectively, thereby ensuring the docking accuracy and sealing effect of the garbage bin 31 relative to the garbage compressor 2, and effectively avoiding the problem of sewage and residue leakage. Secondly, since the lifting mechanism 11 is used to be installed on the ground and the translation mechanism 12 is used to be installed on the garbage compressor 2, the ground only needs to bear the vertical pressure of the garbage bin 31, and the horizontal pulling force of the garbage bin 31 is borne by the garbage compressor 2. This not only improves the sealing strength between the garbage bin 31 and the garbage compressor 2, but also reduces the requirements for ground strength and reduces civil engineering costs.

[0039] In other embodiments, the first slide groove 141 may also be opened on the support seat 13. Accordingly, the first connecting pin 131 is set on the locking hook 14. The support seat 13 can also drive the locking hook 14 to rotate and rise and fall through the cooperation of the first connecting pin 131 and the first slide groove 141, and allow the locking hook 14 to translate relative to the support seat 13 when the locking hook 14 rotates to a preset angle.

[0040] like Figure 2As shown, the support seat 13 includes two support arms 132 which are arranged on opposite sides of the lock hook 14, the first slide groove 141 is opened on the lock hook 14 and penetrates the opposite sides of the lock hook 14, the first connecting pin 131 is passed through the first slide groove 141, and the two ends of the first connecting pin 131 are connected to the two support arms 132 one by one, so that the two support arms 132 are connected into one by the first connecting pin 131, thereby improving the overall structural strength and stability of the two support arms 132, and the lock hook 14 can be supported by the two support arms 132 at the same time, so that the lock hook 14 can be stably rotated under the joint drive of the two support arms 132.

[0041] Preferably, the support seat 13 further includes a connecting seat 133 which is disposed between the two support arms 132 and connects the two support arms 132 into a whole. The connecting seat 133 is located at a middle position along the length direction of the support seat 13 .

[0042] The lifting mechanism 11 includes a base 111 and a lifting cylinder 112. The base 111 is used to be installed on the ground and is hinged to the first end of the support seat 13. The first end of the lifting cylinder 112 is hinged to the base 111, and the second end of the lifting cylinder 112 is hinged to the connecting seat 133. The lifting cylinder 112 is used to drive the support seat 13 to rotate relative to the base 111, thereby driving the second end of the support seat 13 to move up and down.

[0043] The support seat 13 is hinged to the lifting cylinder 112 via the connecting seat 133, which not only enables the force of the lifting cylinder 112 to be applied to the middle position of the support seat 13 along the width direction to ensure force balance, but also further strengthens the fixation of the two support arms 132 via the connecting seat 133 to enhance the supporting strength of the two support arms 132.

[0044] Preferably, the support arm 132 is provided with a slideway 1321 for the preset roller 32 on the trash bin 31 to roll, that is, the support seat 13 supports the roller 32 on the trash bin 31 through the slideway 1321, and when the lock hook 14 drives the trash bin 31 to translate, the roller 32 on the trash bin 31 can roll along the slideway 1321, converting the sliding friction into rolling friction, so as to reduce the hook pulling resistance of the lock hook 14, thereby reducing the power of the translation mechanism 12 and improving the smoothness of the docking and locking.

[0045] Preferably, a guide groove is provided on the slide 1321, and the guide groove is used to embed the roller 32 and guide the rolling direction of the roller 32, so that during the translation of the trash bin 31, the trash bin 31 can be guided to a state facing the compression box 21 through the guiding cooperation of the guide groove and the roller 32, thereby achieving precise positioning.

[0046] In other embodiments, the support arm 132 may also be provided with support wheels (not shown in the figure, the same below) for supporting the trash bin 31. The support arm 132 lifts the trash bin 31 through the support wheels, and can also make the bottom surface of the trash bin 31 roll relative to the support wheels when the locking hook 14 drives the trash bin 31 to translate, thereby reducing the hook pulling resistance.

[0047] Please combine Figure 2 and Figure 6 The trash bin docking and locking device 1 also includes a guiding mechanism 15 for being arranged on the trash bin 31, and the guiding mechanism 15 includes two guiding strips 151 which are arranged on opposite sides of the support seat 13 and are arranged in a "V" shape along the translation direction of the trash bin 31.

[0048] Specifically, the two guide strips 151 are inclined relative to the translation direction of the garbage bin 31, so that the distance between the two guide strips 151 is gradually narrowed in the direction away from the garbage compressor 2. Therefore, when the locking hook 14 drives the garbage bin 31 to move in the direction toward the garbage compressor 2 (at this time, the support seat 13 moves relative to the garbage bin 31 in the direction away from the garbage compressor 2), the garbage bin 31 is guided relative to the support seat 13 through the cooperation between the two guide strips 151 and the support seat 13, so that the garbage bin 31 is aligned with the compression box 21 of the garbage compressor 2, thereby further improving the docking accuracy of the garbage bin 31.

[0049] exist Figure 6 As shown in the figure, preferably, one side of the guiding strip 151 facing the other guiding strip 151 is set as an introduction slope, and the introduction slope is used to guide the support seat 13 into the gap between the two guiding strips 151 to facilitate accurate alignment between the guiding mechanism 15 and the support seat 13.

[0050] Furthermore, the garbage bin docking and locking device 1 also includes a controller (not shown in the figure, the same below) for controlling the lifting mechanism 11 and the translation mechanism 12, and a first sensor and a second sensor electrically connected to the controller respectively, the first sensor being used to detect the height of the garbage bin 31, and the second sensor being used to detect the distance between the garbage bin 31 and the compression box 21, so as to judge whether the garbage bin 31 is lifted to a height level with the compression box 21 through real-time detection by the first sensor, and judge whether the garbage bin 31 and the compression box 21 are completely sealed through real-time detection by the second sensor, so that the controller can accurately control the movement of the lifting mechanism 11 and the translation mechanism 12 under the feedback of the first sensor and the second sensor, so as to realize accurate docking and locking of the garbage bin 31.

[0051] exist Figures 3 to 5 As shown in the figures, the translation mechanism 12 includes a translation cylinder 121 and a fixing seat 122, both of which are used to be installed on the garbage compactor 2, and a connecting rod assembly 123 arranged on the fixing seat 122, the first end of the connecting rod assembly 123 is hinged to the translation cylinder 121, and the second end of the connecting rod assembly 123 is hinged to the locking hook 14.

[0052] Furthermore, the fixing seat 122 is provided with a second slide groove 1221 extending along the locking direction of the lock hook 14, and the lock hook 14 is provided with a second connecting pin 142 inserted in the second slide groove 1221 and used to slide relative to the second slide groove 1221, so that the lock hook 14 can slide in the second slide groove 1221. The support seat 13 is used to drive the lock hook 14 to rotate relative to the second slide groove 1221 through the cooperation of the first connecting pin 131 and the first slide groove 141 during rotation, and the translation cylinder 121 is used to drive the connecting rod assembly 123 to rotate and drive the lock hook 14 to slide along the second slide groove 1221 through the rotation action of the connecting rod assembly 123.

[0053] Specifically, when the lock hook 14 is in an inclined state, the first slide groove 141 and the second slide groove 1221 have an angle to limit the lock hook 14 from being able to translate relative to the support seat 13, but at this time the lock hook 14 can rotate synchronously with the support seat 13 in cooperation with the first connecting pin 131 and the first slide groove 141. When the lock hook 14 is driven to a horizontal state by the support seat 13, the first slide groove 141 and the second slide groove 1221 are parallel to each other, and at this time the translation cylinder 121 can normally drive the lock hook 14 to translate, thereby realizing the action of hooking and pulling the trash bin 31.

[0054] Furthermore, the connecting rod assembly 123 includes a first connecting rod 1231 and a second connecting rod 1232, wherein the first end of the first connecting rod 1231 is hinged to the translation oil cylinder 121, the second end of the first connecting rod 1231 is hinged to the first end of the second connecting rod 1232, and the second end of the second connecting rod 1232 is hinged to the locking hook 14. The first connecting rod 1231 is hinged to the fixing seat 122 at a position between the first end and the second end thereof, so that the first connecting rod 1231 can rotate around the fixing seat 122 under the drive of the translation oil cylinder 121 and drive the second connecting rod 1232 to move, thereby driving the locking hook 14 to translate along the second slide slot 1221 through the second connecting rod 1232.

[0055] The translation mechanism 12 allows the locking hook 14 to rotate freely in the unhooked state through the coordinated cooperation of the first connecting rod 1231 and the second connecting rod 1232, and enables the locking hook 14 to be driven to translate by the translation cylinder 121 in the horizontal state. The transmission structure is simple and efficient, with strong stability. It can also make the distance at which the locking hook 14 tightens the trash bin 31 flexibly and controllably, and can adjust the hook pulling distance in real time according to the elasticity and aging degree of the sealing strip, further ensuring that the trash bin 31 and the compression box 21 have good and stable sealing.

[0056] like Figure 2 As shown, the translation mechanism 12 also includes a limit member 124 installed on the fixed seat 122, and the limit member 124 is provided with a limit hole 1241 corresponding to the second slide groove 1221, and the second connecting pin 142 is provided with a limit pin which is penetrated into the limit hole 1241 and is used to slide along the limit hole 1241. The second connecting pin 142 is guided and limited by the limit hole 1241, thereby further improving the movement stability and smoothness of the locking hook 14 and avoiding jamming.

[0057] like Figure 1 As shown, as a second aspect, an embodiment of the present invention further provides a garbage transfer station 1000, comprising a garbage compactor 2 and the above-mentioned garbage bin docking and locking device 1, wherein the translation mechanism 12 of the garbage bin docking and locking device 1 is installed on the garbage compactor 2, and the garbage compactor 2 is provided with a compression box 21 for compressing garbage. The garbage bin 31 of the garbage transfer vehicle 3 is docked and locked relative to the compression box 21 through the garbage bin docking and locking device 1, effectively ensuring docking accuracy and sealing effect, being able to accurately push the garbage blocks compressed in the compression box 21 onto the garbage bin 31, and avoiding leakage of sewage and residues in the process of pushing the garbage blocks.

[0058] Furthermore, a sealing strip is provided at one end of the compression box 21 facing the trash bin 31 and / or at one end of the trash bin 31 facing the compression box 21. The compression box 21 is sealed relative to the trash bin 31 through the sealing strip to ensure the sealing effect and further avoid leakage of sewage and residue.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
