Description

Technical Field

[0001] This application relates to the field of garden machinery and equipment, and in particular to a foldable wood chipper with a Hall switch. Background Technology

[0002] A branch shredder, also known as a wood chipper, is a mechanical device used to crush garden waste such as branches, leaves, and shrubs into fragments or granules. Its working principle is primarily based on mechanical cutting and a high-speed rotating blade system.

[0003] A wood shredder consists of a main body and a frame for housing the main body. The main body houses the blade system and a drive mechanism that propels the blades to cut branches. When the shredder is in operation, the main body is fixed to the upper part of the frame. Driven by the motor, the blade system rapidly cuts the branches, achieving the purpose of shredding. The frame typically also includes movable structures for rotating the main body and locking mechanisms, allowing the shredder to be folded when not in use.

[0004] Regarding the aforementioned technologies, the inventors believe that when workers are using the paper shredder, they may accidentally touch the locking mechanism, causing the paper shredder to fold. At this time, the paper shredder is still in the running state, thus posing a certain safety hazard. Utility Model Content

[0005] To prevent the shredder from remaining in operation when folded due to accidental activation of the locking mechanism, this application provides a foldable shredder with a Hall switch.

[0006] The foldable wood chipper with a Hall switch provided in this application adopts the following technical solution:

[0007] A foldable wood chipper with a Hall effect switch includes a mounting frame, a collection bin, and a wood chipper main unit. The rear bottom of the wood chipper main unit is rotatably mounted on the mounting frame, which is provided with a locking mechanism for locking the front bottom of the wood chipper main unit. The mounting frame has a cavity for accommodating the collection bin. A Hall effect switch is mounted on the front bottom of the wood chipper main unit. The Hall effect switch is connected in series with the power supply of the wood chipper main unit and is used to control the start and stop of the wood chipper main unit. The collection bin is provided with a magnetic element that cooperates with the Hall effect switch. The wood chipper main unit has a working position and a folding position. When the wood chipper main unit is in the working position, it is positioned on the upper side of the mounting frame, and the Hall effect switch cooperates with the magnetic element to make the Hall effect switch in an on state. When the wood chipper main unit is in the folding position, it is located inside the collection bin, the Hall effect switch is separated from the magnetic element, and the Hall effect switch is in an off state.

[0008] By adopting the above technical solution, a Hall switch is installed at the bottom front of the shredder, connected in series with the power supply of the shredder and used to control the start and stop of the shredder. A magnetic component is installed in the collection box to cooperate with the Hall switch. When the shredder is in the working position, it is positioned on the upper side of the mounting frame, and the Hall switch and magnetic component work together to keep the Hall switch in the connected state. When the shredder is in the folding position, it is located inside the collection box, the Hall switch and magnetic component are separated, and the Hall switch is in the open state. This prevents the shredder from continuing to work when folded due to accidental activation of the locking mechanism, thus improving the safety performance of the shredder. At the same time, when the collection box is separated from the mounting frame, the Hall switch and magnetic component are separated, and the Hall switch is in the open state. This prevents the shredder from starting to work when the collection box is not installed, thus preventing children from accidentally touching the shredder and getting injured.

[0009] Optionally, the top front end of the collection box is provided with a magnetic groove for arranging the magnetic components.

[0010] By adopting the above technical solution, the magnetic components are arranged in the magnetic groove at the top front end of the collection box, making the installation of the magnetic components more compact. This makes the Hall switch less likely to fail due to the detachment of the magnetic components, which helps to further improve the safety performance of the wood chipper.

[0011] Optionally, the number of Hall switches is two, and the two Hall switches are arranged in parallel.

[0012] By adopting the above technical solution, two Hall switches are arranged in parallel and connected in series to the power supply of the wood chipper, so that when one Hall switch fails, the normal operation of the wood chipper can still be guaranteed, which helps to ensure the working stability of the wood chipper.

[0013] Optionally, the two Hall switches are arranged laterally with a spacing of not less than 10cm between them; the magnetic element is arranged facing the corresponding Hall switch.

[0014] By adopting the above technical solution and setting a larger gap between the two Hall switches, the probability of mutual interference between the two paired magnets is reduced, further ensuring the working stability of the wood chipper.

[0015] Optionally, the front end of the collection box is provided with a fixed protrusion, the mounting frame has an arrangement groove for arranging the fixed protrusion, both sides of the arrangement groove are provided with vertically arranged fixed protrusions, and both sides of the fixed protrusion are provided with a fixing groove for locking the fixed protrusions.

[0016] By adopting the above technical solution, fixed protrusions are vertically arranged in the arrangement slot of the mounting frame, and fixed slots corresponding to the fixed protrusions are set in the fixed protrusions at the top front end of the collection box, so that the collection box is not easy to fall off from the placement cavity when it is placed in the placement cavity of the mounting frame.

[0017] Optionally, a handle structure is provided at the fixed protrusion, the handle structure including a handle groove formed on the bottom side of the fixed protrusion and the opening of the handle groove is arranged downward.

[0018] By adopting the above technical solution, a downward-opening handle groove is provided at the fixed protrusion of the collection box, which helps to remove the collection box from the placement cavity.

[0019] Optionally, the front bottom of the shredder host is provided with a first locking groove along the width direction; the locking mechanism includes a locking crank that is horizontally rotatably mounted on the mounting frame, a locking spring connected to the locking crank and driving the locking crank to always have a rotating direction toward the shredder host, and an unlocking handle connected to one end of the locking crank and used to drive the locking crank to rotate; the unlocking handle is rotatably mounted on the mounting bracket.

[0020] By adopting the above technical solution, the locking relationship between the locking mechanism and the working host when the twig chipper is in the working position is disclosed. When the twig chipper is in the working position, it is located at the top of the mounting frame, and the locking crank is locked in the first locking groove at the bottom front end of the twig chipper, thereby locking the twig chipper to the top of the mounting frame. The above technical solution also discloses the specific structure of the locking mechanism. When the twig chipper is in the working position, by rotating the unlocking handle, the locking crank rotates and separates from the first locking groove, the twig chipper disengages from the locking mechanism and rotates to the folding position. At this time, releasing the unlocking handle resets the locking crank, thereby realizing the folding of the twig chipper.

[0021] Optionally, the top of the shredder has a second locking groove for locking by the locking crank; when the shredder is in the folding position, the locking crank is locked in the second locking groove of the shredder.

[0022] By adopting the above technical solution, the locking relationship between the locking mechanism and the working host when the shredder is in the folding position is disclosed. When the shredder is in the folding position, the top of the shredder is located at the front side of the inner cavity of the collection box, and the locking crank is locked in the second locking groove at the top of the shredder, thereby locking the shredder in the placement cavity of the mounting frame.

[0023] Optionally, the placement cavity has an opening on the front side of the mounting frame for the collection box to pass through; the mounting frame has guide grooves on both sides of the placement cavity; the collection box has guide protrusions for cooperating with the guide grooves.

[0024] By adopting the above technical solution, guide rails are set on both sides of the placement cavity of the mounting frame, and guide protrusions that cooperate with the guide rails are arranged on both sides of the collection box, realizing the sliding and disassembly of the collection box and the mounting frame.

[0025] Optionally, the mounting frame is provided with a limiting part on the rear side of the placement cavity for the collection box to abut against; when the fixing protrusion is arranged in the placement groove, the tail end of the collection box abuts against the limiting part.

[0026] By adopting the above technical solution, a fiber part is provided on the rear side of the placement cavity of the mounting bracket for the tail end of the collection box to abut against, so that the collection box will not fall out of the rear of the placement cavity when it is slidably installed on the mounting frame, which helps to improve the installation stability of the collection box on the mounting frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By installing a Hall switch at the bottom front of the shredder and a magnetic component that works with the Hall switch in the collection box, when the shredder is in the working position, it is positioned on the upper side of the mounting frame, and the Hall switch is in the connected state in conjunction with the magnetic component. When the shredder is in the folding position, it is located inside the collection box, the Hall switch is separated from the magnetic component, and the Hall switch is in the off state. This prevents the shredder from remaining in operation when folded due to accidental activation of the locking mechanism. When the collection box is not installed in the mounting frame, the Hall switch is separated from the magnetic component, and the Hall switch is in the off state. This prevents children from accidentally touching the shredder and getting injured, thus improving the safety performance of the shredder.

[0029] 2. By arranging two Hall switches in parallel and connecting them in series with the power supply of the wood chipper, the normal operation of the wood chipper can still be guaranteed even if one Hall switch fails, which helps to ensure the working stability of the wood chipper.

[0030] 3. By arranging the two Hall switches horizontally and setting a large gap between them, the probability of mutual interference between the two paired magnets is reduced, further ensuring the working stability of the wood chipper. Attached Figure Description
