The part of the clamping wheel clamping plate 382 extending into the rear wheel mounting plate 381 is set as an inclined panel structure, so as to adjust the position of the rear wheel mounting plate 381.

[0051] Please also read Fig. 9 , Fig.10 The pickup bucket 40 of this embodiment includes a bucket front plate 41, a bucket rear plate 42 arranged relative to the bucket front plate 41, and a bucket left plate 43 and a bucket right plate 44 for connecting the bucket front plate 41 and the bucket rear plate 42. The bucket front plate 41 is a transparent plate, so that people can observe the complete pickup process of the pickup bucket 40 through the bucket front plate 41, thereby improving people's visual experience when using the vending machine.

[0052] In this embodiment, the pickup bucket 40 further includes a bottom door 45 rotatably connected to the cargo bucket front plate 41 and the cargo bucket rear plate 42, and a driving assembly for controlling the rotation of the bottom door 45. The bottom door 45 can selectively cover the bottom of the pickup bucket 40, so as to realize the function of the pickup bucket 40 to contain the goods dropped from the cargo channel 101, and the pickup bucket 40 can realize the bottom door 45 opening the bottom of the pickup bucket 40 by the rotation drive of the bottom door 45 by the driving assembly, thereby realizing the pickup bucket 40 to discharge the goods to the pickup window 12 of the vending machine.

[0053] In this embodiment, the driving assembly includes a motor 461 fixed on the cargo box rear plate 42, a power arm 462 provided on the rotating shaft of the motor 461, and a connecting rod 463 hinged to the power arm 462, and one end of the connecting rod 463 away from the power arm 462 is hinged to the bottom door 45, and the motor 461 drives the power arm 461 to rotate, and drives the bottom door 45 to rotate relative to the cargo box rear plate 42 through the connecting rod 463, so as to realize the rotation control of the bottom door 45 by the driving assembly.

[0054] The power arm 461, the connecting rod 462, the bottom door 45 and the cargo bucket rear plate 42 together constitute a four-link transmission mechanism, and when the bottom door 45 covers the bottom of the pickup bucket 40, the connection node between the power arm 461 and the connecting rod 462 is at a dead point position, that is, when the bottom door 45 closes the bottom of the pickup bucket 40, the power arm 461 and the connecting rod 462 are in an almost collinear position. When the bottom door 45 on the pickup bucket 40 of this embodiment covers the bottom of the pickup bucket 40, the bottom door 45 can carry cargo of sufficient weight, thereby ensuring the control of the cargo loading and discharge of the pickup bucket 40.

[0055] In this embodiment, a position sensor 421 is provided on the cargo bucket rear plate 42, an extension convex portion 4621 is provided on the power arm 461, and when the bottom door 45 covers the bottom of the pickup bucket 40, the extension convex portion 4621 is arranged in contact with the position sensor 421. That is, when the pickup bucket 40 of this embodiment is in use, when the bottom door 45 covers the bottom of the pickup bucket 40, the position sensor 421 senses the extension convex portion 4621 and sends a corresponding signal; and when the bottom door 45 opens the bottom of the pickup bucket 40, the extension convex plate 4611 is separated from the position sensor 421 as the power arm 461 rotates, and at this time, the position sensor 421 cannot send a corresponding signal to the outside because it fails to sense the extension convex portion 4621. That is to say, this embodiment can realize signal feedback when the bottom door 45 covers the bottom of the pickup bucket 40 through the reasonable structural arrangement of the position sensor 421 and the extension protrusion 4621, thereby meeting the use requirements of the intelligent control of the vending machine.

[0056] Furthermore, a bottom door limiting screw 422 is provided on the cargo bucket rear plate 42, and the bottom door limiting screw 422 is provided above the connecting rod 462 for limiting the connecting rod 462, so that the bottom door limiting screw 422 can adjust the position of the connecting rod 462 when the power arm 461 drives the connecting rod 462 to swing and reset, thereby ensuring that the connecting rod 462 can return to the starting position, and then realize the position adjustment of the bottom door 45 when covering the bottom of the cargo bucket 40, thereby ensuring that the bottom door 45 covers the bottom of the cargo bucket 40.

[0057] In this embodiment, a cargo guide plate 431 is provided on the cargo bucket left plate 43, which is used to guide the cargo to move away from the cargo bucket rear plate 42 and the cargo bucket left plate 43, so as to prevent the cargo from falling from the corresponding cargo channel 101 into the pickup bucket 40 and leaking out of the pickup bucket 40 due to bouncing or other reasons, and to ensure that the movement of the cargo is not blocked. It should be noted that when the pickup bucket 40 of this embodiment receives the cargo falling from the cargo channel 101, the cargo enters the pickup bucket 40 from above the cargo bucket rear plate 42; and the gear transmission mechanism 70 is provided on the outer side wall of the cargo bucket left plate 43.

[0058] Specifically, the cargo guide plate 431 of this embodiment is configured as a sloped structure that is smaller at the top and larger at the bottom, and the left side wall and the right side wall of the cargo guide plate 431 are respectively configured as sloped structures, so that the sloped side walls of the cargo guide plate 431 are used to guide the cargo.

[0059] In this embodiment, the left plate 43 of the cargo bucket is set as an insulation plate, so that when the pickup bucket 40 discharges the goods in it to the pickup window 12, the pickup bucket 40 can cooperate with the isolation plate 11 to achieve the function of isolating the left and right cabinets of the box body 10, so that when the vending machine is not in use, the pickup bucket 40 is set at the position of the pickup window 12, thereby preventing the cooler or heater in the box body 10 from leaking out through the pickup window 12.

[0060] Furthermore, the pickup bucket 40 of this embodiment is rotatably connected to a bottom side door 451 between the front plate 41 and the rear plate 42 of the pickup bucket, and the bottom side door 451 cooperates with the bottom door 45 to selectively cover the bottom of the pickup bucket 40. One side of the bottom side door 451 is always placed on the bottom door 45, thereby ensuring that the bottom of the pickup bucket 40 is covered. The structural setting of the bottom side door 451 allows the bottom door 45 to avoid the isolation plate in the box body 10 when it is opened, thereby ensuring the normal opening of the bottom of the pickup bucket 40.

[0061] The gear transmission mechanism 70 is used to cooperate with the push plate mechanism 30, and can selectively cooperate with the cargo lane front wheel 342 on the push plate mechanism 30, so as to realize the driving of the cargo lane push plate 35 on the push plate mechanism 30 to move in the cargo lane 101. In this embodiment, the gear transmission mechanism 70 is fixed to the outer side wall of the cargo bucket left plate 43 of the pickup bucket 40.

Specifically, a connecting shaft (not shown) may be fixed on the opposite surfaces between the first gear mounting plate 73 and the second gear mounting plate 74, and the second gear 72 is sleeved on the connecting shaft, wherein the connecting shaft may be connected and fixed to the first gear mounting plate 73 or the second gear mounting plate 74 according to usage requirements.

[0064] The first gear 71 is pressed and matched with the first gear mounting plate 73 and / or the second gear mounting plate 74; and the gear transmission mechanism 70 can drive the first gear mounting plate 73 and the second gear mounting plate 74 to swing back and forth through the first gear 71, and when the first gear mounting plate 73 and the second gear mounting plate 74 are swing-limited, the first gear 71 can drive the second gear 72 to rotate. That is to say, when the gear transmission mechanism 70 of this embodiment is working, the static friction on the contact surface between the first gear 71 and the first gear mounting plate 73 and / or the second gear mounting plate 74 can be used to realize the swing drive of the first gear mounting plate 73 and the second gear mounting plate 74, and then due to the swing limit, the static friction is converted into a sliding groove, and the rotation drive of the second gear 72 is realized. It should be noted that when the first gear mounting plate 73 and the second gear mounting plate 74 are swung to a limited position in one direction, the second gear 72 can engage with the front wheel 342 of the cargo lane, and then the gear transmission mechanism 70 drives the cargo lane push plate 35 on the push plate mechanism 30 to move in the cargo lane 101 when working.

[0065] In this embodiment, the first gear mounting plate 73 and the second gear mounting plate 74 are connected by the elastic force adjustment component 76, wherein an elastic element 77 is provided between the first gear mounting plate 73 and the second gear mounting plate 74, and the elastic force adjustment component 76 can adjust the distance between the first gear mounting plate 73 and the second gear mounting plate 74, so as to adjust the pressure of the first gear 71 when it is pressed and matched with the first gear mounting plate 73 and / or the second gear mounting plate 74. That is to say, in this embodiment, the elastic force adjustment component 76 can be used to adjust the pressure of the first gear mounting plate 73 and the second gear mounting plate 74 on the elastic element 77, so as to adjust the pressure of the first gear 71 when it is pressed and matched with the first gear mounting plate 73 and / or the second gear mounting plate 74, thereby achieving the maximum static friction force that the first gear 71 can be subjected to when rotating, so as to ensure that when the gear transmission mechanism 70 is working, the first gear mounting plate 73 and the second gear mounting plate 74 can be driven to swing by driving the first gear 71 to rotate.

[0066] Specifically, the elastic force adjustment component 76 includes an adjustment screw 761 fixed on the second gear mounting plate 74, an elastic force adjustment nut 762 and a locking nut 763 screwed to the adjustment screw 761; the adjustment screw 761 passes through the first gear mounting plate 73, wherein the portion of the adjustment screw 761 extending out of the first gear mounting plate 73 is connected to the elastic force adjustment nut 762 and the locking nut 763 in sequence; the elastic force adjustment nut 762 can adjust the pressure of the first gear mounting plate 73 and the second gear mounting plate 74 on the elastic element 77, and is limited by the locking nut 763. In other words, people can adjust the pressure of the first gear mounting plate 73 and the second gear mounting plate 74 on the elastic element 77 by screwing the elastic force adjustment nut 762, and finally limit it by the locking nut 763, so as to facilitate people to adjust the elastic adjustment component 76.

It can be understood that the elastic force adjustment component 76 is not limited to that shown in the figure, and those skilled in the art can set the number of the elastic force adjustment component 76 to one according to the needs of use, and the elastic force adjustment component 76 is set on the mid-perpendicular line of the first gear 71.

[0068] The elastic element 77 is configured as an elastic gasket, and the elastic gasket abuts against the first gear 71. Specifically, the elastic gasket can be sleeved on the rotating shaft of the driving motor 75. It can be understood that the elastic element 77 is not limited to being configured as an elastic gasket. Those skilled in the art can configure the elastic element 77 as a spring according to the use requirements, wherein the two ends of the spring abut against the first gear mounting plate 73 and the second gear mounting plate 74 respectively, and are limited and fixed relative to the first gear mounting plate 73 and the second gear mounting plate 74. Specifically, limiting bosses (not shown) can be respectively provided on the facing surfaces of the first gear mounting plate 73 and the second gear mounting plate 74, and the springs can be sleeved on the limiting bosses respectively. Alternatively, the elastic element 77 configured as an elastic gasket can be directly abutted and matched with the first gear mounting plate 73 and the second gear mounting plate 74.

[0070] Specifically, the limiting structure includes a limiting screw 702 and a gear position sensor 703, and the limiting screw 702 and the gear position sensor 703 are both fixed to the left plate 43 of the cargo box, and are separated on the two outer sides of the first gear mounting plate 73 and the second gear mounting plate 74, and realize the swing limiting of the first gear mounting plate 73 and the second gear mounting plate 74 through their respective abutment.

[0071] In this embodiment, the first gear mounting plate 73 is provided with a 731, and the limit baffle 731 can respectively abut against the limit screw 702 or the gear position sensor 703 to limit the back and forth swing of the first gear mounting plate 73 and the second gear mounting plate 74. The limit baffle 731 and the first gear mounting plate 73 are set as an integrated structure. It can be understood that the limit baffle 731 can also be set on the second gear mounting plate 74.

[0072] As can be seen from the above, the structural arrangement of the gear position sensor 703 and the limit screw 702 on the gear transmission mechanism 70 of this embodiment enables the first gear mounting plate 73 and the second gear mounting plate 74 to swing back to the starting position each time when the gear transmission mechanism 70 is working, so that the error amount is balanced each time the vending machine takes out goods, which has the effect of improving the stability of the vending machine when taking out goods.
