[0030] The feeding structure of the conventional wet garbage degradation equipment adopts a split design, and the opening and closing of the feeding port door, the dumping of the weighing hopper, and the opening and closing of the feed port door are separate steps, which require multiple driving components, high manufacturing cost, and long operation time. In view of the above problems, the present invention provides a feeding structure of wet garbage degradation equipment, which adopts a linkage design, so that one driving device can realize the coordinated action of multiple mechanisms, reducing the manufacturing cost, simplifying the feeding process, and shortening the operation time.

[0031] The feeding structure of the wet garbage degradation equipment is further explained below in conjunction with the accompanying drawings.

[0032] See also Figure 1 , Figure 1 A front view of the feeding structure of the wet garbage degradation equipment of the present invention is shown.

[0033] A feeding structure of a wet garbage degradation device, the wet garbage treatment device comprises a feeding bin 10 and a degradation bin 20, the feeding bin 10 is provided with a feeding port connected to the outside and a feeding port connected to the degradation bin 20, the feeding structure comprises:

[0034] A weighing hopper 30 is disposed between the feeding port and the feed port. A rotating shaft 31 is fixed to one end of the weighing hopper 30 close to the feed port. The rotating shaft 31 is rotatably connected to the feeding bin 10 via a bearing 32.

[0035] A feed inlet door, which is a double-opening sliding door, is provided at the feed inlet. The feed inlet door includes a large door 41 away from the weighing hopper 30 and a small door 42 close to the weighing hopper 30;

[0036] The linkage mechanism includes a driving device 50 for driving the main door 41 to move, a first connecting rod 60 for driving the rotating shaft 31 to rotate as the main door 41 moves, and a second connecting rod 70 for driving the small door 42 to move as the rotating shaft 31 rotates. The driving device 50 is fixed on the main door 41, the first connecting rod 60 is hinged between the main door 41 and the rotating shaft 31, and the second connecting rod 70 is hinged between the small door 42 and the rotating shaft 31.

[0037] Specifically, garbage is fed into the weighing hopper 30 of the feeding bin 10 through the feeding port, and the garbage is weighed by the weighing hopper 30. At the same time, the driving device 50 of the linkage mechanism drives the gate 41 of the feeding port door to move away from the weighing hopper 30. When the gate 41 moves, the rotating shaft 31 of the weighing hopper 30 is driven to rotate by the first connecting rod 60 and the bearing 32, thereby driving the second connecting rod 70 to push the small door 42 to move toward the weighing hopper 30, thereby realizing the linkage and mutual coordination of the two actions of opening the feeding port door and dumping the weighing hopper 30. When the garbage is completely dumped from the weighing hopper 30 into the degradation bin 20, the driving device 50 of the linkage mechanism drives the gate 41 of the feed inlet door to move toward the weighing hopper 30. While the gate 41 moves, the first connecting rod 60 and the bearing 32 drive the rotating shaft 31 of the weighing hopper 30 to rotate, and then drive the second connecting rod 70 to push the small door 42 to move away from the weighing hopper 30, thereby realizing the linkage and mutual coordination of the closing of the feed inlet door and the resetting of the weighing hopper 3. The degradation bin 20 uses microorganisms to degrade the garbage in the bin, and the garbage is discharged from the discharge bin after degradation. The driving device 50 can be any device such as an electric push rod or a cylinder that can drive the gate 41 to reciprocate.

[0038] It should be noted that the opening position of the feed inlet door (i.e., the docking position of the main door 41 and the small door 42) should be properly matched with the flipping angle of the weighing hopper 30 to avoid interference with each other and ensure that the garbage can smoothly enter the degradation bin 20 during the entire flipping process of the weighing hopper 30. Similarly, the closing speed of the feed inlet door should be properly matched with the reset angle of the weighing hopper 30 to avoid interference with each other and ensure that if there is residual garbage, it can still fall into the degradation bin 20 when the weighing hopper 30 is not completely reset. Preferably, a brush or scraper is installed at the lower part of the feed bin 10 at the gap between the feed bin 10 and the feed inlet door (including the main door 41 and the small door 42) to ensure that the feed inlet door plays a cleaning role when it is opened and closed smoothly. Further, a rubber pad is installed between the main door 41 and the small door 42 to play a buffering and sealing role when the feed inlet door is closed.

[0039] The present invention adopts a double-opening sliding door as the feed port door, which can better cooperate with the tipping of the weighing hopper 30 and avoid blocking the weighing hopper 30 during tipping, so that the weighing hopper 30 can completely tip out the garbage inside it; the feed port door and the weighing hopper 30 are connected by a linkage mechanism, so that only one driving device is needed to realize the coordinated action of the feed port and the weighing hopper 30, thereby ensuring the synchronization of each action.

[0040] As a preferred embodiment, Figure 2 and Figure 5 , Figure 2 The diagram shows the overall connection state of the feed port door and the linkage mechanism when the weighing hopper is in the dumping state; Figure 5 The diagram shows the overall connection status of the feed port door and linkage mechanism when the weighing hopper is in reset state:

[0041] The first connecting rod 60 includes a first swing arm 61 and a second swing arm 62 pivotally connected to the first swing arm 61. The end of the first swing arm 61 is pivotally connected to the door 41, and the end of the second swing arm 62 is fixedly connected to the rotating shaft 31.

[0042] The second connecting rod 70 includes a third swing arm 71 and a fourth swing arm 72 pivotally connected to the third swing arm 71 . The end of the third swing arm 71 is pivotally connected to the small door 42 , and the end of the fourth swing arm 72 is fixedly connected to the rotating shaft 31 .

[0043] Specifically, when the driving device 50 drives the gate 41 of the feed inlet door to move (including moving in a direction away from the weighing hopper 30 and moving in a direction close to the weighing hopper 30), the first swing arm 61 rotates with the movement of the gate 41, changes the pivot angle between the first swing arm 61 and the second swing arm 62 and drives the second swing arm 62 to rotate. Under the action of the bearing 32, the rotating shaft 31 rotates with the rotation of the second swing arm 62, and drives the fourth swing arm 72 fixed to the rotating shaft 31 to rotate, changes the pivot angle between the third swing arm 71 and the fourth swing arm 72 and drives the small door 42 to move through the third swing arm 71 (opposite to the direction of movement of the gate 41, so as to realize the relative opening or relative closing of the feed inlet door). The use of the above-mentioned connecting rod structure makes the structure of the linkage mechanism simple and ensures the synchronization of the linkage between the various actions.

[0044] After many calculations and verifications, a better coordination scheme is obtained, which can avoid interference between the feed port door, the weighing hopper 30 and the linkage mechanism during operation, while ensuring that the garbage can smoothly enter the degradation bin 20 during the entire flipping process of the weighing hopper 30, and ensure that if there is any residual garbage, it can still fall into the degradation bin 20 before the weighing hopper 30 is completely reset.

[0045] Specifically, the preferred matching scheme is as follows:

[0046] The length of the gate 41 along the moving direction is 250 mm, the length of the small gate 42 along the moving direction is 110 mm, the length of the first swing arm 61 is 260 mm, the length of the second swing arm 62 is 165 mm, the length of the third swing arm 71 is 180 mm, and the length of the fourth swing arm 72 is 170 mm. Figure 6 and Figure 7 , Figure 6 The diagram shows the connection state of the gate and the first connecting rod when the weighing hopper is in the reset state; Figure 7 The diagram shows the connection state of the small door and the second connecting rod when the weighing hopper is in the reset state. When the feed inlet door is in the fully closed state (i.e., the large door 41 and the small door 42 are in the docking state), the first angle a between the second swing arm 62 and the large door 41 is 90 degrees, and the second angle b between the fourth swing arm and the small door 42 is 60 degrees.

[0047] Further cooperation Figure 3 and Figure 4 , Figure 3 The diagram shows the connection state of the gate and the first connecting rod when the weighing hopper is in the dumping state; Figure 4The diagram shows the connection state of the small door and the second connecting rod when the weighing hopper is in the dumped state. When the feed inlet door is in the fully opened state (i.e., the main door 41 and the small door 42 are completely separated), the second swing arm 62 drives the rotating shaft 31 and the fourth swing arm 72 to rotate 70 degrees, i.e., the first angle a changes from 90 degrees to 20 degrees, and the second angle b changes from 60 degrees to negative 10 degrees.

[0048] The above scheme is a better matching scheme for the given sizes of the main door 41, the small door 42 and the weighing funnel 30. In practical application, it can be adjusted according to the actual given sizes. However, it should be noted that when the feed inlet door is fully closed, the first angle a should not exceed 90 degrees to ensure that when the main door 41 is opened, the first swing arm 61 can smoothly pull the second swing arm 62. At the same time, the second angle b is smaller than the first angle a, and the third angle c between the third swing arm 71 and the small door 42 should be between the first angle a and the second angle c. The first angle a and the second angle b are between to ensure that the third swing arm 71 pushes the small door 42 to move in the direction opposite to the moving direction of the large door 41; in addition, the sum of the lengths of the first swing arm 61 and the second swing arm 62 should be greater than the opening width of the feed port door, that is, when the feed port door is fully opened, the fourth angle d between the first swing arm 61 and the second swing arm 62 should be less than 180 degrees, to ensure that when the feed port door is reset and closed, the first swing arm 61 can push the second swing arm 62 to rotate in the opposite direction.

[0049] As a preferred embodiment, the first connecting rod 60 and the second connecting rod 70 are disposed on two sides of the weighing hopper 30 opposite to each other.

[0050] Specifically, the rotating shaft 31 is arranged along a full length perpendicular to the flipping direction of the weighing hopper 30, and the two ends of the rotating shaft 31 extend out of the two sides of the weighing hopper 30. There are two bearings 32, which are respectively arranged at the two ends of the rotating shaft 31 and have a distance from the adjacent side of the weighing hopper 30. The first connecting rod 60 and the second connecting rod 70 are relatively arranged on both sides of the weighing hopper 30 and are connected to the corresponding distance sections of the rotating shaft 31 to ensure that the weighing hopper 30 is not interfered by the linkage mechanism when it is flipped.

[0051] As another preferred embodiment: Figure 8 , Figure 8The schematic diagram of the distribution state of the first connecting rod and the second connecting rod of the present invention is shown. The number of the first connecting rod 60 is two, and the two first connecting rods 60 are relatively arranged on both sides of the weighing hopper 30; the number of the second connecting rod 70 is two, and the two second connecting rods 70 are relatively arranged on both sides of the weighing hopper 30, and the two second connecting rods 70 are respectively located on the relatively outer sides of the two first connecting rods 60. Of course, the two second connecting rods 70 can also be respectively located between the two first connecting rods 60 and the weighing hopper 30. This embodiment combines the single-sided single-group connecting rod structure (such as Figure 1 The structure of the single-sided double-group connecting rod is improved into a single-sided double-group connecting rod structure, so that the force on the feeding structure is more balanced, the operation of the linkage mechanism is more stable, and the situation that the single-sided single-group connecting rod may have an overload during actual application is avoided.

[0052] As a preferred embodiment: guide rails are provided on opposite sides of the feed port, and the large door 41 and the small door 42 are installed on the guide rails through a sliding device.

[0053] Specifically, the sliding device can be any device that can cooperate with the guide rail to realize the relative sliding of the gate 41 and the small door 42. For example, for the guide rail in the form of a slideway, the sliding device can be a roller rotatably connected to the gate 41 and the small door 42, and the roller is embedded in the slideway. The sliding device can also be a transmission roller group arranged along the guide rail, and the gate 41 and the small door 42 are placed on the sliding device. For another example, for the guide rail in the form of a rail, the sliding device can be a pulley rotatably connected to the gate 41 and the small door 42, and the groove of the pulley is engaged with the guide rail. Through the above structure, the opening and closing of the feed port door is smoother and smoother. Of course, other methods can also be selected to achieve it in combination with actual conditions.

[0054] As a preferred embodiment: a limiting component for limiting the moving range of the main door 41 and the small door 42 is provided on the guide rail.

[0055] Specifically, the setting position of the limit assembly should be determined according to the specific structure of the linkage mechanism to ensure that the movement of the main door 41 and the small door 42 and the flipping of the weighing hopper 30 linked by the linkage mechanism are synchronized and do not interfere with or block each other.

[0056] As a preferred embodiment: a feeding port door and a control module for controlling the automatic opening and closing of the feeding port door are provided at the feeding port, and the driving device 50 is connected to the control module.

[0057] Specifically, the control module can use PLC and be installed on the wet garbage degradation equipment, preferably at the feeding port door. The feeding port door can be automatically opened by swiping a card or scanning a QR code. It is controlled uniformly by PLC, which facilitates the monitoring of the actions of each mechanism, makes the actions of each mechanism more closely connected, shortens the entire operating time, and improves work efficiency.

[0058] As a preferred embodiment: a weighing device 33 is installed at the bottom of the weighing hopper 30, and the weighing device 33 is connected to the control module.

[0059] Specifically, by setting the weighing device 33, the weighing hopper 30 can automatically weigh the garbage when it receives it, and upload the weight information to the control module. In order to facilitate the on-site understanding of the garbage processing situation, a display screen for displaying time, weight and other information can be set on the control module. By selecting PLC as the control module, other commonly used programs can also be expanded to improve the management of the wet garbage degradation equipment.

[0060] The following is a comparison of the process of single-time feeding by taking a single person bag feeding as an example. Fig. 9 , Fig. 9 A comparison diagram of the single feeding process of a conventional wet garbage degradation device and the wet garbage degradation device of the present invention is shown.

[0061] The process of single feeding of conventional wet garbage degradation equipment with a general feeding structure (i.e., process 1) is as follows:

[0062] The feeding port door is opened. The user sends a signal to the control module by swiping a card or scanning a code. Then the control module controls the driving device of the feeding port door to drive the feeding port door to open.

[0063] Manually put the garbage into the weighing hopper, and weigh the garbage through the weighing hopper;

[0064] The feeding port door is closed, and the driving device of the feeding port door is controlled by the control module to drive the feeding port door to be closed;

[0065] The feed inlet door is opened, and the driving device of the feed inlet door is controlled by the control module to drive the feed inlet door to open;

[0066] The weighing hopper dumps the waste after weighing. When the weighing is completed and the feed inlet door is open, the weighed waste is dumped into the degradation bin through the feed inlet door.

[0067] The weighing hopper resets and automatically resets after dumping;

[0068] The feed inlet door is closed, and the control module controls the driving device of the feed inlet door to drive the feed inlet door to close.

[0069] The wet garbage degradation equipment with the feeding structure of the present invention performs a single feeding process (i.e., process 2) as follows:

[0070] The feeding port door is opened. The user sends a signal to the control module by swiping a card or scanning a code. Then the control module controls the driving device of the feeding port door to drive the feeding port door to open.

[0071] Manually put the garbage into the weighing hopper, and weigh the garbage through the weighing hopper;

[0072] The feeding port door is closed, and the driving device of the feeding port door is controlled by the control module to drive the feeding port door to be closed;

[0073] The feed port door is opened while the weighing hopper is weighed and dumped. When the weighing of the weighing hopper is finished, the control module controls the linkage mechanism to drive the feed port door to open, and simultaneously drives the weighing hopper to flip, thereby simultaneously realizing the opening of the feed port door and the dumping of the weighed garbage into the degradation bin through the feed port door.

[0074] The feed port door closes as the weighing hopper is reset. After the weighing hopper is dumped, it automatically resets and drives the feed port door to close simultaneously.

[0075] By comparing the above process 1 and process 2, it can be clearly seen that the wet garbage degradation equipment using the feeding structure of the present invention simplifies the feeding process, shortens the operating time, and reduces the production cost.

[0076] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
