Description

Technical Field

[0001] This utility model belongs to the field of fallen leaf collection technology, specifically, it relates to an automatic tilting device for a fallen leaf collection box. Background Technology

[0002] In urban environmental maintenance and landscaping management, leaf removal is a periodic and demanding task. With the acceleration of urbanization, urban green areas are constantly expanding, and the number of trees is increasing. Every autumn, when leaves fall in abundance, the amount of fallen leaves produced is considerable.

[0003] Traditional methods of collecting fallen leaves mostly involve manual sweeping in conjunction with ordinary leaf collection bins. These bins are typically fixed structures, requiring sanitation workers to manually move them to designated locations for dumping after they are full, or using forklifts or other equipment for assistance. This method has several drawbacks: firstly, it is physically demanding for sanitation workers, requiring frequent movement of heavy collection bins, resulting in low efficiency and difficulty in handling large areas and high volumes of fallen leaves; secondly, manual handling can easily lead to leaf spillage, causing secondary pollution, while the use of forklifts and other equipment increases operating costs and space requirements.

[0004] Therefore, there is an urgent need for an automatic leaf collection bin tilting device that is simple in structure, low in cost, and stable and reliable, in order to improve leaf collection efficiency, reduce the labor intensity of sanitation workers, and at the same time ensure the long-term stable operation of the device to meet the actual needs of urban greening and sanitation work. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic tipping device for a leaf collection box that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an automatic tilting device for a leaf collection box, including a leaf collection box base, and further including: a semi-circular tilting plate rotatably connected to the inner side of the leaf collection box base, a box support seat fixedly connected to the inner wall of the two sets of semi-circular tilting plates, and a support bracket provided at the bottom of the box support seat; a tension spring fixedly connected inside the support bracket, a trigger pressing seat fixedly connected to the top of the tension spring, a trigger block fixedly connected to the bottom of the trigger pressing seat, and a drive switch fixedly connected to the end of the support bracket near the trigger block.

[0007] Furthermore, the trigger block slides inside the load-bearing bracket.

[0008] Furthermore, a base support frame is fixedly connected to the bottom of the load-bearing bracket, and the base support frames are evenly distributed at the bottom of the load-bearing bracket.

[0009] Furthermore, a semi-circular limiting groove is fixedly connected to the front of the box's load-bearing base for the rotation of the semi-circular tilting plate on the leaf collection box base.

[0010] Furthermore, the bottom of the load-bearing base of the housing is fixed with a load-bearing shaft, which is circular, and the trigger pressure seat is an upward-facing semi-circular groove opening, with the load-bearing shaft corresponding to the trigger pressure seat.

[0011] Furthermore, a drive motor is fixedly connected to the load-bearing bracket, and a push rod is fixedly connected to the output end of the drive motor for driving the extension and retraction of the push rod.

[0012] Furthermore, a housing support is fixedly connected to the end of the push rod away from the drive motor.

[0013] Furthermore, the push rod extends and retracts under the drive of the drive motor. The end of the push rod away from the drive motor is fixedly connected to the box support. As the push rod extends, it generates a thrust on the box support. Since the semi-circular tilting plate is rotatably connected to the inside of the leaf collection box base, and the box support is fixedly connected to the inner wall of the semi-circular tilting plate, under the thrust of the push rod, the box support causes the semi-circular tilting plate to rotate around the connection point with the leaf collection box base. This rotation causes the entire leaf collection box to gradually tilt. When it tilts to a certain angle, the leaves inside the box automatically tip out under the action of gravity, completing the leaf tipping process.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1. This utility model uses a weight-triggered mechanism. When the fallen leaves in the leaf collection box reach a certain weight, the lower pressure seat is triggered, which drives the trigger block to automatically trigger the drive switch, thereby starting the drive motor to achieve automatic tilting. This eliminates the need for frequent manual checks on the full load of the collection box and manual tilting, greatly saving manpower inspection and operation time. It allows sanitation workers to focus more on other sanitation work and improves the overall efficiency of leaf collection.

[0016] 2. After the dumping is completed, the tension spring can quickly drive the device to reset, preparing for the next collection, shortening the time the collection box is not in operation, and enabling continuous and efficient collection and dumping of fallen leaves.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Example: Refer to Figures 1-4 An automatic tipping device for a leaf collection box includes a leaf collection box base 1 and a semi-circular tipping plate 2 rotatably connected to the inner side of the leaf collection box base 1. The inner walls of the two sets of semi-circular tipping plates 2 are fixedly connected to a box support 21. A support bracket 211 is provided at the bottom of the box support 21. A tension spring 221 is fixedly connected inside the support bracket 211. A trigger pressing seat 223 is fixedly connected to the top of the tension spring 221. A trigger block 224 is fixedly connected to the bottom of the trigger pressing seat 223. A drive switch 222 is fixedly connected to the end of the support bracket 211 near the trigger block 224.

[0026] The trigger block 224 is slidably connected inside the load-bearing bracket 211.

[0027] The bottom of the load-bearing bracket 211 is fixedly connected to a base load-bearing frame 22, which is evenly distributed at the bottom of the load-bearing bracket 211.

[0028] The front of the box support 21 is fixedly connected with a semi-circular limiting groove 23 for the rotation of the semi-circular tilting plate 2 on the leaf collection box base 1.

[0029] The bottom of the load-bearing base 21 of the housing is fixed with a load-bearing shaft 24, which is circular. The trigger pressure seat 223 is an upward-facing semi-circular groove opening, and the load-bearing shaft 24 corresponds to the trigger pressure seat 223.

[0030] A drive motor 26 is fixedly connected to the load-bearing bracket 211, and a push rod 25 is fixedly connected to the output end of the drive motor 26 for driving the extension and retraction of the push rod 25.

[0031] The end of the push rod 25 away from the drive motor 26 is fixedly connected to the housing support 21.

[0032] Driven by the drive motor 26, the push rod 25 extends and retracts. The end of the push rod 25 away from the drive motor 26 is fixedly connected to the box support 21. As the push rod 25 extends, it generates a thrust on the box support 21. Since the semi-circular tilting plate 2 is rotatably connected to the inner side of the leaf collection box base 1, and the box support 21 is fixedly connected to the inner wall of the semi-circular tilting plate 2, under the thrust of the push rod 25, the box support 21 drives the semi-circular tilting plate 2 to rotate around the connection point with the leaf collection box base 1. This rotation causes the entire leaf collection box to gradually tilt. When it tilts to a certain angle, the leaves inside the box automatically tilt out under the action of gravity, completing the leaf tilting process.

[0033] When the leaf collection box of this utility model is put into use, as time goes by and leaves continue to fall, the leaves inside the box gradually accumulate. When the leaves accumulate to a certain weight, the weight of the entire collection box increases significantly. This weight change first acts on the box body support 21, which acts as the "force-bearing center" of the entire device, bearing the weight of the collection box and the leaves inside. The weight-bearing shaft 24 at its bottom, as a key component for weight transmission, begins to press down to trigger the pressure seat 223. The trigger pressure seat 223 is shaped like a structure with an upward semi-circular groove opening. The groove corresponds to the weight-bearing shaft 24 and can accurately bear the pressure transmitted by the weight-bearing shaft 24.

[0034] Under the downward pressure of the load-bearing shaft 24, the trigger pressing seat 223 slides downward inside the load-bearing bracket 211. The trigger block 224, which is fixedly connected to the bottom of the trigger pressing seat 223, moves downward together with the trigger pressing seat 223. When the trigger block 224 contacts the drive switch 222, which is fixedly connected to one end inside the load-bearing bracket 211, it is as if the start button has been pressed, triggering the entire automatic tilting program. During this process, the tension spring 221, which is fixedly connected inside the load-bearing bracket 211, is compressed. The tension spring 221 acts as an energy storage device, storing elastic potential energy when compressed, providing power support for the subsequent reset process.

[0035] When the drive switch 222 is triggered, the current is turned on and the drive motor 26 starts to work. The drive motor 26, as the power source of the entire device, is like the "heart" of the device, providing power for the tilting action. After the motor starts, its output end begins to rotate, driving the push rod 25 fixedly connected to the output end. The push rod 25 can be regarded as an extension of the force of the drive motor 26.

[0036] Driven by the drive motor 26, the push rod 25 extends and retracts. The end of the push rod 25 away from the drive motor 26 is fixedly connected to the box support 21. As the push rod 25 extends, it generates a thrust on the box support 21. Since the semi-circular tilting plate 2 is rotatably connected to the inner side of the leaf collection box base 1, and the box support 21 is fixedly connected to the inner wall of the semi-circular tilting plate 2, under the thrust of the push rod 25, the box support 21 drives the semi-circular tilting plate 2 to rotate around the connection point with the leaf collection box base 1. This rotation causes the entire leaf collection box to gradually tilt. When it tilts to a certain angle, the leaves inside the box automatically tilt out under the action of gravity, completing the leaf tilting process.

[0037] After the fallen leaves have been tilted, in order for the leaf collection box to continue collecting fallen leaves normally, the device needs to be restored to its initial state. At this time, the drive motor 26 reverses and the push rod 25 begins to retract. At the same time as the push rod 25 retracts, the previously compressed tension spring 221 begins to recover its deformation. When the tension spring 221 recovers its deformation, it generates an upward pulling force. This pulling force acts on the trigger pressure seat 223, pulling the trigger pressure seat 223 to move upward and reset. During the upward movement of the trigger pressure seat 223, it drives the connected components, including the box support seat 21 and the semi-circular tilting plate 2, to rotate back to their initial positions.

[0038] During the process of the semicircular tilting plate 2 returning to its initial position, the semicircular limiting groove 23, which is fixedly connected to the front of the box support 21, plays a crucial role. The semicircular limiting groove 23 cooperates with the corresponding structure on the leaf collection box base 1, acting like a track to ensure that the semicircular tilting plate 2 runs along the correct trajectory during rotation, preventing deviation or wobbling, and ensuring the stability and accuracy of the rotation. At this point, the entire automatic tilting device for the leaf collection box completes a full working cycle, preparing for the next leaf collection.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
