Abstract
Description
Technical Field
[0001] This utility model relates to the field of lawnmower technology, specifically to a lawnmower debris collection structure. Background Technology
[0002] A lawnmower is a type of garden machinery that uses rotating or reciprocating sharp blades to trim lawns or ground vegetation to an aesthetically pleasing height. Its core function is to replace traditional manual tools (such as sickles and scythes) to achieve efficient, high-quality, and low-labor-intensity lawn maintenance. A typical lawnmower consists of a power system, a cutting system, a walking system, and a control system. Some lawnmowers also have a grass handling system to collect the cut grass. Through the coordinated operation of these systems, the lawnmower achieves fully mechanized operation from power output, vegetation cutting, material handling to operator safety control.
[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: after the existing lawnmower debris collection structure is full of debris generated from mowing, the debris needs to be discharged. The existing debris collection structure requires stopping the machine and removing the debris collection structure from the main body of the lawnmower. Then the debris collection structure needs to be manually emptied to discharge the debris. The operation requires stopping the machine for disassembly, and additional installation steps are required after discharge. The process is complicated, cumbersome, and inconvenient to use. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a simple and convenient lawnmower debris collection structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lawnmower debris collection structure, comprising a collection device detachably installed on one side of the lawnmower main unit, the collection device comprising a collection body and a disassembly structure disposed on one side of the top of the collection body, the collection body comprising a collection bin and a discharge gate disposed on one side of the collection bin, the collection bin having an inlet on the same side as the disassembly structure, the collection bin having a power motor disposed on the opposite side of the discharge gate, a screw fixedly installed on the shaft of the power motor penetrating the collection bin and movably engaged with the collection bin through a bearing, and a push plate with its edge abutting against the inner wall of the collection bin meshing on the screw.
[0006] A further improvement is that a limiting plate is integrally formed at the end of the screw.
[0007] A further improvement is that the pusher plate includes a pusher plate body whose edge fits against the inner wall of the collection chamber and a threaded ring embedded in the middle section of the pusher plate body, wherein the inner wall of the threaded ring meshes with the outer wall of the screw.
[0008] A further improvement is that the bottom end of the push plate body is integrally formed with a wedge-shaped bottom block.
[0009] A further improvement is that the feed inlet includes a material opening integrally formed on one side of the collection chamber and a curved first swing handle that is movably engaged with the top of the material opening. The bottom of the material opening is movably engaged with a second swing handle that has the same structure as the first swing handle. The material opening can be closed when the second swing handle and the first swing handle are closed. An elastic piece is provided between the bottom side of the second swing handle and the side of the collection chamber.
[0010] A further improvement is that a weight is provided at the bottom of the first swing handle.
[0011] A further improvement is that the disassembly and assembly structure includes a hardened block disposed on one side of the top of the collection body and a snap-in groove integrally formed on the hardened block, and the hardened block is integrally formed with a raised rail on the other side of the snap-in groove.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the lawnmower main unit cuts the grass and feeds it into the collection body, the thrust generated by the grass being transported and moved opens the first and second swing handles of the feed inlet, allowing the grass to enter the collection bin. After the collection bin is full, the grass feeding is stopped, and the first swing handle hangs down naturally under the action of gravity, while the second swing handle is lifted by the action of the elastic plate, thereby sealing the material opening to prevent leakage. Then, the power motor is started, which drives the screw to rotate, causing the push plate to move laterally under the action of the screw and the threaded ring on it, simultaneously opening the discharge door on one side of the collection bin, allowing the grass to be pushed out from the discharge door. At this time, it is only necessary to place bags or other objects at the discharge door for collection, thus quickly and automatically discharging without disassembling the collection structure. The discharge operation is simple and convenient to use. Attached Figure Description

Detailed Implementation
[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0016] See Figure 1-5As shown, the technical solution adopted in this specific embodiment is: a lawnmower debris collection structure, including a collection device 2 detachably installed on one side of the lawnmower main unit 1. The collection device 2 includes a collection body 21 and a disassembly / assembly structure disposed on one side of the top of the collection body 21. The disassembly / assembly structure includes a hardened block 22 disposed on one side of the top of the collection body 21 and an insertion groove 23 integrally formed on the hardened block 22. A lifting rail 24 is integrally formed on the other side of the hardened block 22 located in the insertion groove 23. The hardened block 22 is made of high-strength engineering plastic (such as nylon or POM), and the internal insertion groove 23 has an inverted U-shaped cross-section for interlocking with a corresponding connecting protrusion on the side wall of the lawnmower main unit 1. The lifting rail 24 is used to limit the connection with the side of the main unit 1 during connection, preventing the collection device 2 from being inserted too deeply. The entire disassembly / assembly structure is quickly fixed by the weight of the collection device 2 itself and the suspension effect of the connecting protrusion of the main unit 1, without the need for additional fasteners. The collection device 2 can be separated by lifting it upwards. The collecting body 21 includes a collecting bin 211 and a discharge gate 212 located on one side of the collecting bin 211. The inner wall of the collecting bin 211 is preferably a smooth plane to facilitate the entry and discharge of crushed materials and reduce the resistance when the push plate 217 moves. The collecting bin 211 is provided with a feed inlet 213 on the same side as the disassembly structure. The feed inlet 213 includes a material opening 41 integrally formed on one side of the collecting bin 211 and a curved first swing handle 42 that is movably engaged with the top of the material opening 41. A second swing handle 45 with the same structure as the first swing handle 42 is movably engaged at the bottom of the material opening 41. The material opening 41 can be closed when the second swing handle 45 and the first swing handle 42 are closed. An elastic piece 44 is provided between the bottom side of the second swing handle 45 and the side of the collecting bin 211. A power motor 216 is provided on the side of the collecting bin 211 opposite to the discharge gate 212. A shaft of the power motor 216 is fixedly installed with a part that penetrates the collecting bin 211 and is movably engaged with the collecting bin 211 through a bearing. The screw 214 is engaged with a push plate 217 whose edge is attached to the inner wall of the collection chamber 211. The push plate 217 includes a push plate body 31 whose edge is attached to the inner wall of the collection chamber 211 and a threaded ring 32 embedded in the middle section of the push plate body 31. The inner wall of the threaded ring 32 is engaged with the outer wall of the screw 214. In use, when the lawnmower main unit 1 cuts the grass and feeds it into the collection body 2, the thrust generated by the movement of the grass pushes the feed inlet 213. The first swing handle 42 and the second swing handle 45 are opened, allowing the hay to enter the collection bin 211. After the collection bin 211 is full, the hay feeding is stopped, and the first swing handle 42 hangs down naturally under the action of gravity, while the second swing handle 45 is lifted up under the action of the elastic piece 44, thereby sealing the material opening 41 to prevent leakage. Specifically, the first swing handle 42 and the second swing handle 45 are movably installed on the upper and lower edges of the material opening 41 through a rotating shaft, and can swing freely within a certain angle.The elastic sheet 44 is a one-piece stainless steel sheet or a high-strength plastic sheet. One end is fixed to the outer wall of the collection chamber 211, and the other end abuts against the outer side of the bottom of the second swing handle 45, providing a continuous upward torsional torque to the second swing handle 45, causing it to swing upward in its natural state to close the material opening 41. During operation, the flow of broken material blown or thrown out from the discharge port of the main unit 1 impacts the inner sides of the first swing handle 42 and the second swing handle 45. Its thrust overcomes the gravity of the first swing handle 42 and the elastic force of the second swing handle 45, causing them to swing outward, thereby opening the material opening 41 to allow the broken material to enter. After the material flow stops, the first swing handle 42 automatically droops under gravity, and the second swing handle 45 automatically swings upward under the elastic force of the elastic plate 44. The two then re-close to form an effective seal, preventing material leakage during discharge or machine vibration. Subsequently, the power motor 216 is started, driving the screw 214 to rotate. This causes the push plate body 31 of the push plate 217 to move laterally under the action of the screw 214 and its threaded ring 32. The threaded ring 32 is made of a self-lubricating material (such as nylon or POM) and forms a helical transmission pair with the screw 214. The push plate body 31 is preferably made of a lightweight and high-strength material (such as ABS engineering plastic), and the sealing scraper on its outer edge maintains slight contact with the inner wall of the collection chamber 211. When discharge is required, the discharge door 212 is opened, and the power motor 216 is started to drive the screw 214 to rotate. The push plate 217 then moves axially along the screw 214 under the screw drive, smoothly pushing the debris in the collection bin 211 out of the discharge door 212. Simultaneously, the discharge door 212 on one side of the collection bin 211 is opened, allowing the grass to be pushed out from the position of the discharge door 212. At this time, only bags or other items need to be placed at the discharge door 212 for collection. Thus, the discharge is quick and automatic without disassembling the collection structure. After the push plate 217 moves to the end of its stroke, the power motor 216 is controlled to reverse, so that the push plate 217 returns to the starting end of the collection bin 211, preparing for the next collection operation. At the same time, if maintenance is required, the main body 1 of the mower can be lifted directly, so that its connecting end is disengaged from the slot 23 of the disassembly structure for quick disassembly. Unlike traditional debris collection structures, there is no need for bolt disassembly and other steps. The discharge operation and maintenance disassembly operation are simple and convenient to use. The end of the screw 214 is integrally formed with a limiting plate 215, which helps to prevent the push plate 217 from moving excessively and disengaging from the screw 214. The bottom end of the push plate body 31 is integrally formed with a wedge-shaped bottom block 33, which is beneficial to the push plate body 31 to scoop up the grass deposited at the bottom of the inner wall of the collection bin 211 when it moves, so that it can be pushed and discharged better. This wedge design helps to reduce the front resistance of the push plate 217 when it moves, especially when dealing with compacted or wet grass. The bottom of the first swing handle 42 is provided with a weight 43, which helps to increase the weight at the bottom of the first swing handle 42. Thus, when the feeding of hay stops, the weight 43 can make the first swing handle 42 descend quickly, ensuring that it can close quickly and reliably with the second swing handle 45.
[0017] The working principle of this utility model is as follows: When the lawnmower main unit 1 cuts the grass and feeds it into the collection body 2, the thrust generated by the movement of the grass pushes open the first swing handle 42 and the second swing handle 45 of the feed inlet 213, allowing the grass to enter the collection bin 211. After the collection bin 211 is full, the grass feeding stops, allowing the first swing handle 42 to hang down naturally under gravity, while the second swing handle 45 is lifted by the elastic plate 44, thereby sealing the material opening 41 to prevent leakage. Then, the power motor 216 is started, driving the screw 214 to rotate, which in turn causes the push plate 217 to move. The push plate body 31 moves laterally under the action of the screw 214 and the threaded ring 32 on it, and simultaneously opens the discharge door 212 on one side of the collection chamber 211, so that the grass can be pushed out from the discharge door 212. At this time, you only need to place the bag or other objects at the discharge door 212 to collect them. Thus, the grass can be discharged quickly and automatically without disassembling the collection structure. At the same time, if maintenance is required, the main body 1 of the mower can be lifted directly so that its connecting end is disengaged from the slot 23 of the disassembly structure, and it can be quickly disassembled without the need for bolt disassembly and other steps as in the traditional debris collection structure. The discharge operation and maintenance disassembly operation are simple and convenient to use.
