Description

Technical Field

[0001] This application relates to the technical field of lawnmowers, and in particular to a lawnmower with anti-clogging function. Background Technology

[0002] Lawn mowers are common tools used for the maintenance of lawns, gardens, sports fields, and other outdoor spaces. A cutting chamber is located at the bottom of the lawn mower, and multiple first-pass grass inlets communicating with this chamber are located at the front of the bottom. A blade, rotating horizontally, is rotatably connected to the center of the cutting chamber. The blade rotates at a certain height above the ground, cutting off excessively long grass and resulting in a smooth and aesthetically pleasing lawn.

[0003] Existing lawnmowers are prone to clogging the grass inlet when collecting the cut grass, which affects the collection of weeds and increases the workload of subsequent cleanup.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: when collecting the cut grass, the lawnmower is prone to clogging the grass inlet channel, affecting the collection of cut weeds and increasing the workload. Utility Model Content

[0005] The purpose of this application is to provide a lawnmower with anti-clogging function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a lawnmower with anti-clogging function, employing the following technical solution:

[0007] A lawnmower with anti-clogging function includes a lawnmower body, which comprises a main body, a handle, a front wheel, a rear wheel, and a grass collection box. The handle is located at the top of the main body. The front wheel is located at the bottom of the main body away from the handle, and the rear wheel is located at the bottom of the main body near the handle. The grass collection box is fixedly connected to one side of the rear wheel. A cutting blade is disposed between the front wheel and the rear wheel. A weed inlet is located on the side of the cutting blade near the rear wheel. A conveying mechanism is disposed within the weed inlet. The conveying mechanism includes a set of fixed frames, a rotating rod, a spiral conveyor shaft, a belt, and a rotary motor. The set of fixed frames is respectively disposed at both ends of the weed inlet. A rotating rod is inserted through the center of the fixed frame. A spiral conveyor shaft is fixed to the outside of the rotating rod. A belt is sleeved on one end of the rotating rod, and the belt is driven by the output shaft of the rotary motor.

[0008] By adopting the above technical solution, the lawnmower's cutting blades cut the lawn that needs to be trimmed and then enter the grass collection box through the weed inlet. Under the action of the rotary motor, the belt rotates, which in turn drives the rotating rod to rotate, causing the spiral conveyor shaft to rotate and transport the weeds into the grass collection box. This avoids clogging the weed inlet when there are too many cut weeds, thus playing a better anti-clogging role.

[0009] Preferably, multiple blades are fixed on the outer side of the spiral conveyor shaft.

[0010] By adopting the above technical solution, the spiral conveyor shaft rotates along with the spiral conveyor shaft, avoiding long weeds from getting tangled in it, which helps to cut the weeds and further prevents blockage.

[0011] Preferably, a weed collection box is provided at the end of the weed inlet away from the cutting blade. The weed collection box includes a collection port, a U-shaped baffle and a storage box. The collection port is provided at the end of the weed inlet away from the cutting blade. The storage box is fixedly connected to the end of the collection port away from the weed inlet. A U-shaped baffle is provided at the connection between the storage box and the collection port.

[0012] By adopting the above technical solution, the cut weeds can be collected, and the baffle can block the weeds from entering the weed collection box, preventing the weeds from falling out of the weed collection box.

[0013] Preferably, a fan is fixed on the side of the grass collection box away from the weed collection port, and an air outlet is provided on the side of the grass collection box near the fan.

[0014] By adopting the above technical solution, the weeds can be quickly sucked into the weed collection box by the action of the fan when collecting weeds.

[0015] Preferably, the side of the storage box closest to the fan is made of breathable non-woven fabric.

[0016] By adopting the above technical solution, ventilation is facilitated, which is beneficial for the absorption of weeds by the fan.

[0017] Preferably, a clamping mechanism is provided on the outside of the collection port. The clamping mechanism includes a clamping plate, a telescopic rod and a spring. The clamping plates are symmetrically arranged on both sides of the collection port. Multiple telescopic rods are fixed on the side of the clamping plate away from the collection port. A spring is sleeved on the thin end of the telescopic rod. The end of the telescopic rod away from the clamping plate is fixedly connected to the inner wall of the weed inlet.

[0018] By adopting the above technical solution, the clamping plate is squeezed by the telescopic rod and spring to fix the weed collection box, making it convenient to collect weeds.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The design of the conveying mechanism and blades allows the lawnmower's cutting blades to cut the lawn that needs to be trimmed and then enter the grass collection box through the weed inlet. Under the action of the rotary motor, the belt rotates, which in turn drives the rotating rod to rotate, causing the spiral conveyor shaft to rotate and transport the weeds into the grass collection box. This prevents the weed inlet from being blocked when there are too many cut weeds, thus playing a good anti-clogging role. The blades cut long weeds to prevent them from getting tangled in the spiral conveyor shaft, further preventing clogging.

[0021] 2. The weed collection box and clamping mechanism facilitate the collection of weeds, prevent weeds from falling out, and improve the collection efficiency. Attached Figure Description

[0032] The implementation principle of a lawnmower 15 with anti-clogging function in this application embodiment is as follows:

[0033] When the lawnmower is weeding, the cutting blade 2 cuts the grass. Under the action of the fan 7 and the rotary motor 45, the cut weeds enter the weed collection box 6 through the weed inlet 3. The rotary motor 45 drives the spiral conveyor shaft 43 to rotate, effectively transporting the weeds into the weed collection box 6, preventing the weeds from clogging the weed inlet 3. During the rotation, the blade 5 cuts and crushes the longer weeds again, preventing the weeds from getting tangled on the spiral conveyor shaft 43, further preventing blockage. After the fan 7 sucks the weeds into the weed collection box 6, the U-shaped baffle 62 blocks the weeds, preventing them from falling out.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
