[0014] In the aforementioned waste sorting and collection bin adapted to the beach cleaning robot, there are two collection boxes, and the volume of the collection box closer to the sieve plate is larger than the volume of the collection box farther away from the sieve plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, the interior of the housing includes an operating chamber. A sand-leaking plate is connected to the opening of the operating chamber via a connecting rod assembly. A bracket is positioned above the sand-leaking plate, and a sieve plate is mounted on the bracket. A first motor is mounted on the upper side of the sand-leaking plate, and the output shaft of the first motor is connected to a disc. An eccentric shaft is positioned at the edge of the disc, and the end of the eccentric shaft is fixedly connected to the lower side of the bracket. A mounting base is also provided on the upper side of the sand-leaking plate, and a rocker arm is hinged to the side of the mounting base. The upper end of the rocker arm is hinged to the upper side of the bracket. A sand-leaking outlet is provided at the lower part of the sand-leaking plate. In use, the sand-leaking plate is opened via the connecting rod assembly, the sieve plate is moved out of the operating chamber, and the first motor is started. The first motor drives the disc to rotate, thereby driving the eccentric shaft to perform circular motion. During rotation, the eccentric shaft can drive the lower side of the bracket to move back and forth and up and down. During the movement of the bracket, the rocker arm on the front side will swing back and forth with the bracket. The cleaning robot dumps the garbage onto a screen plate. As the screen plate moves with the support frame, it gradually tilts the garbage downwards, causing it to move into the operating chamber. During this movement, sand in the garbage passes through the screen plate onto a sand-leaking plate, then slides down to the sand-leaking opening and falls to the ground. This process effectively filters the sand from the garbage, facilitating subsequent garbage processing and recycling and reducing the adverse effects of fine sand on the recycling equipment.

[0017] 2. In this invention, the sand-filtering plate is connected to the operating chamber via a connecting rod assembly, and a cover plate is hinged to the side of the sand-filtering plate. The connecting rod assembly includes an electric push rod fixed to the inner wall of the operating chamber, with a first connecting rod hinged to the telescopic end of the electric push rod. A guide groove is provided on the inner wall of the operating chamber, and a slider is disposed within the guide groove. One end of the first connecting rod is connected to the slider, and the other end of the first connecting rod is hinged to the surface of the sand-filtering plate. A second connecting rod is hinged to the inner wall of the operating chamber, with its side hinged to the side of the first connecting rod, and a third connecting rod hinged to the end of the second connecting rod, with the end of the third connecting rod also hinged to the surface of the sand-filtering plate. In use, the sand-filtering plate is opened via the connecting rod assembly for sand screening. The cover plate hangs down under gravity and contacts the ground, providing good support. After use, the sand-leaking plate is rotated by the linkage assembly and moved into the operating chamber, reducing the overall size of the equipment. The cover plate rests on top of the sand-leaking plate under its own weight, preventing rainwater and other debris from falling into the operating chamber.

[0018] 3. In this invention, a winding box is fixedly installed on the inner wall of the operating chamber. A winding motor is installed inside the winding box, and the output shaft of the winding motor is connected to a winding reel. A connecting wire is wound on the winding reel, and one end of the connecting wire passes through the front side of the winding box and connects to the upper side of the sand-leaking plate. Since the linkage assembly bears a significant load from the sand-leaking plate and cover plate during operation, the winding motor can be activated to unwind the wire when the sand-leaking plate is opened, thus sharing some of the tension since one end of the connecting wire is connected to the sand-leaking plate. When the sand-leaking plate is closed, the winding motor can rewind the wire, pulling the sand-leaking plate upwards and helping the linkage assembly close the sand-leaking plate.

[0019] 4. In this invention, the bracket has a structure that is wider at the top and narrower at the bottom. The wider top allows waste to fall onto the bracket more easily, while the narrower bottom ensures that the waste falls accurately into the operating chamber. The bracket is equipped with a sieve plate, which has a stepped structure from top to bottom. This extends the retention time of waste on the sieve plate, allowing more time for filtering sand from the waste.

[0020] 5. In this invention, there are two collection boxes, and the volume of the collection box closer to the sieve plate is larger than the volume of the collection box farther from the sieve plate. During the sand filtration process, the rotation of the disc and eccentric shaft causes the sieve plate to bounce up and down, causing the waste to jump on the sieve plate and gradually move towards the operating chamber. Lighter waste, due to the vibration of the sieve plate, falls into the collection box at the far end, while heavier waste falls into the collection box at the near end. Since dry waste and wet waste have significant differences in weight, the above operation can pre-sort the waste, facilitating subsequent waste processing.

[0021] 6. In this invention, the housing contains an installation cavity, inside which is a second motor. The output shaft of the second motor is connected to a gear. An extension arm is located within the installation cavity, with a toothed groove on its upper side that meshes with the gear. A distance sensor is mounted on the extension arm. A through hole, communicating with the installation cavity, is located on the front side of the housing, directly opposite the extension arm. In use, the second motor can be started beforehand to rotate the gear, thereby moving the extension arm. The extension arm passes through the through hole and extends forward, as shown in the attached diagram. When the extension arm reaches the target position, the second motor is turned off, and the cleaning robot moves closer to the housing. The distance sensor on the extension arm senses the distance between the cleaning robot and the housing. When the cleaning robot reaches the appropriate area, it stops moving, allowing it to better empty the waste into the waste collection bin. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0032] Example: A trash sorting and collection bin adapted to a beach cleaning robot, as shown in the attached document. Figure 1 and attached Figure 8 As shown, the device includes a housing 1, inside which is a mounting cavity 26. Inside the mounting cavity 26 is a second motor 27, and the output shaft of the second motor 27 is connected to a gear 28. Inside the mounting cavity 26 is an extension arm 5. The upper side of the extension arm 5 is provided with a tooth groove 501 that meshes with the gear 28. A distance sensor, also called a displacement sensor, is provided on the extension arm 5, which can sense the distance between objects. The front side of the housing 1 is provided with a through hole 4 that communicates with the mounting cavity 26, and the through hole 4 is positioned directly opposite the extension arm 5.

[0033] In use, the second motor 27 can be started beforehand to drive the gear 28 to rotate, thereby moving the extension arm 5. The extension arm 5 passes through the through hole 4 and extends forward, as shown in the attached figure. Figure 2 As shown. When the extendable arm 5 moves to the target position, the second motor 27 is turned off, and then the cleaning robot moves closer to the container 1. The distance sensor on the extendable arm 5 can sense the distance between the cleaning robot and the container 1. When the cleaning robot moves to the appropriate area, it stops moving, so that the cleaning robot can better dump the garbage into the garbage collection bin.

[0034] The housing 1 has an internal cavity 24, and a power supply 25 is installed inside the cavity 24. Since it is difficult to find other power supply equipment on the beach, the power supply 25 can supply power to various electrical devices inside the housing 1. Furthermore, a charging cable can be installed on the power supply 25, which is arranged along the extension arm 5. After the extension arm 5 is extended, the cleaning robot can be charged through the charging cable.

[0035] The interior of the housing 1 has an operating compartment 9, and the opening of the operating compartment 9 is connected to a sand-leaking plate 14 via a linkage assembly, as shown in the attached figure. Figure 4 and attached Figure 5 As shown, the linkage assembly includes an electric push rod 19 fixed to the inner wall of the operating chamber 9, with a first connecting rod 20 hinged to the telescopic end of the electric push rod 19; a guide groove 23 is provided on the inner wall of the operating chamber 9, and a slider is provided in the guide groove 23; one end of the first connecting rod 20 is connected to the slider, and the other end of the first connecting rod 20 is hinged to the surface of the sand-leaking plate 14; a second connecting rod 21 is hinged to the inner wall of the operating chamber 9, the side of the second connecting rod 21 is hinged to the side of the first connecting rod 20, and a third connecting rod 22 is hinged to the end of the second connecting rod 21, with the end of the third connecting rod 22 hinged to the surface of the sand-leaking plate 14.

[0036] Initially, the sand-leaking plate 14 is in a closed state, as shown in the attached diagram. Figure 5As shown. In use, the electric push rod 19 is activated, extending and pushing the first connecting rod 20 forward. The end of the first connecting rod 20 moves the sand-leaking plate 14 out of the operating chamber 9. Since the side of the first connecting rod 20 is hinged to the side of the second connecting rod 21, and the end of the second connecting rod 21 is hinged to the inner wall of the operating chamber 9, the movement of the first connecting rod 20 can drive the second connecting rod 21 to rotate. The upper end of the second connecting rod 21, through the third connecting rod 22, moves the sand-leaking plate 14 out of the operating chamber 9. Through the above operation, the sand-leaking plate 14 can be rotated out of the operating chamber 9. A cover plate 2 is hinged to the upper side of the sand-leaking plate 14. Both the surface of the sand-leaking plate 14 and the cover plate 2 are provided with connecting plates, and the corresponding two connecting plates are hinged to each other. During the process of removing the sand-leaking plate 14 from the operating chamber 9, the cover plate 2 will droop under the action of gravity and rotate relative to the sand-leaking plate 14 until the lower end of the cover plate 2 contacts the ground, thus providing support. See attached diagram for details. Figure 3 As shown. After use, simply retract the electric push rod 19 to close the sand-leaking plate 14. The specific process is the reverse of the opening process described above, and will not be elaborated further here. After the sand-leaking plate 14 rotates and closes, the cover plate 2 will rest on the upper side of the sand-leaking plate 14 under the action of gravity, completely blocking the opening of the operating chamber 9, thereby preventing rainwater and other debris from falling into the operating chamber 9.

[0037] A winding box 10 is fixedly installed on the inner wall of the operating chamber 9. A winding motor is installed inside the winding box 10, and the output shaft of the winding motor is connected to a winding reel. A connecting wire 11 is wound on the winding reel, with one end of the connecting wire 11 passing through the front side of the winding box 10 and connecting to the upper side of the sand-leaking plate 14. Since the linkage assembly bears a significant load on the sand-leaking plate 14 and the cover plate during operation, the winding motor can be activated to unwind the wire when the sand-leaking plate 14 is opened to reduce the load. Because one end of the connecting wire is connected to the sand-leaking plate 14, it can share some of the tension. When the sand-leaking plate 14 is closed, the winding motor can rewind the wire, pulling the connecting wire back into the winding box 10 and causing the sand-leaking plate 14 to rotate upwards, thus helping the linkage assembly close the sand-leaking plate 14.

[0038] As attached Figure 6 and attached Figure 7As shown, a bracket 12 is provided above the sand-leaking plate 14. The bracket 12 has a structure that is wider at the top and narrower at the bottom. The wider top allows the waste to fall onto the bracket 12 more easily, while the narrower bottom allows the waste to fall accurately into the operating chamber 9. A screen plate 13 is provided on the bracket 12. To simplify the manufacturing process, the screen plate 13 can be designed as a planar structure. Preferably, in this embodiment, the screen plate 13 has a stepped structure from top to bottom, which can prolong the retention time of waste on the screen plate 13, thereby allowing more time for filtering the sand in the waste. A first motor 16 is provided on the upper side of the sand-leaking plate 14. The output shaft of the first motor 16 is connected to a disc 17. An eccentric shaft 18 is provided at the edge of the disc 17. The end of the eccentric shaft 18 is fixedly connected to the lower side of the bracket 12. A mounting base 29 is also provided on the upper side of the sand-leaking plate 14. A rocker arm 30 is hinged to the side of the mounting base 29. The upper end of the rocker arm 30 is hinged to the upper side of the bracket 12. A sand-leaking port 15 is provided at the lower part of the sand-leaking plate 14.

[0039] After the cleaning robot moves to the target position, the sand-leaking plate 14 is opened via the linkage assembly, and the sieve plate 13 is moved out of the operating chamber 9. The first motor 16 is started, which drives the disc 17 to rotate, thereby driving the eccentric shaft 18 to perform circular motion. During the rotation of the eccentric shaft 18, the lower side of the bracket 12 can move back and forth and up and down. During the movement of the bracket 12, the rocker arm 30 on the front side will swing back and forth with the bracket 12. The cleaning robot pours the garbage onto the sieve plate 13. As the bracket 12 moves, the sieve plate 13 can gradually tilt the garbage downwards, causing the garbage to jump on the sieve plate and gradually move into the operating chamber 9. During the movement, the sand in the garbage will fall through the sieve plate 13 onto the sand-leaking plate 14, then slide down to the sand-leaking outlet 15 and fall to the ground. Through the above operation, the function of filtering sand in garbage can be achieved.

[0040] The operating chamber 9 is equipped with two collection boxes 3, with the volume of the collection box 3 closer to the sieve plate 13 being larger than that of the collection box 3 farther from the sieve plate 13. During the sand filtration process, the rotation of the disc 17 and the eccentric shaft 18 causes the sieve plate 13 to bounce up and down, causing the waste to jump on the sieve plate 13 and gradually move into the operating chamber 9 along the sieve plate 13. Lighter waste, due to the bouncing of the sieve plate 13, falls into the far-end collection box 3, while heavier waste falls into the near-end collection box 3. Since dry waste and wet waste have significant differences in quality, the above operation can pre-sort the waste, facilitating subsequent waste processing. The operating chamber 9 is equipped with a movable frame 6, with casters 8 at its bottom. The collection box 3 is mounted on the movable frame 6. The inner wall of the operating chamber 9 has a limiting groove, and the side of the movable frame 6 has a limiting rod 7, one end of which extends into the corresponding limiting groove. The side of the housing 1 has an opening communicating with the operating chamber 9. A pressure sensor is installed on the movable frame 6. The pressure sensor can detect pressure signals and convert them into usable output electrical signals according to a certain rule. The pressure sensor can monitor the amount of waste collected in the collection box 3. Furthermore, a control screen can be installed on the housing 1 and connected to the pressure sensor, allowing the user to more intuitively understand the amount of waste in the collection box 3. When the waste in the collection box 3 needs to be processed, simply pull the movable frame 6 to move the collection box 3 out of the opening.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
