Description

Technical Field

[0001] This utility model relates to the field of wool shearing technology, and in particular to a shock-resistant and noise-reducing DC brushless motor for wool shearing. Background Technology

[0002] The DC brushless motor for wool shears is a core drive component designed specifically for electric wool shears. It adopts a brushless structure and is powered by DC power to provide high-speed and stable power to the shearing blades. It is suitable for efficient, low-noise, and long-term continuous shearing operations for livestock such as sheep and goats in livestock farming scenarios.

[0003] When workers need to use wool shears, they install a brushless motor on the shears so that the brushless motor can drive the shears. However, existing brushless motors vibrate during use, causing the connection between the brushless motor and the wool shears to loosen, which in turn leads to the wool shears malfunctioning during use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that wool shears may malfunction during use in the prior art, and to propose a shock-resistant and noise-reducing DC brushless motor for wool shears.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shock-resistant and noise-reducing DC brushless motor for wool shearing, including a driver, a handle above the driver, a shock-absorbing device on the upper surface of the driver, the shock-absorbing device including a metal ring, the metal ring being disposed between the driver and the handle, rubber pads being fixedly connected to both the upper and lower surfaces of the metal ring, one rubber pad being placed on the upper surface of the driver and the other rubber pad being placed on the lower surface of the handle, a sleeve opening being provided on the surface of the metal ring, the sleeve opening being located below the handle, an anti-rotation block being fixedly connected to the upper surface of the driver, the anti-rotation block being slidably connected to the inner wall of the sleeve opening, a connecting assembly being provided on the surface of the handle, the connecting assembly including a socket, a positioning rod, and a storage hole, the socket being opened on the top of the driver, the storage hole being opened on the surface of the handle, the socket being able to cooperate with the driver to achieve the purpose of storing the positioning rod, and the storage hole being able to cooperate with the handle to achieve the purpose of adjusting the positioning rod.

[0006] Preferably, the internal thread of the storage hole is connected to a positioning rod, which is inserted into the internal socket. The positioning rod can cooperate with the storage hole and the socket to connect the driver and the grip together.

[0007] Preferably, the top of the driver is provided with a noise reduction device, the noise reduction device includes a main block, the main block is fixedly connected to the top of the driver, the main block is internally threaded with a positioning block, the main block can cooperate with the driver to support the main block, and the main block can cooperate with the positioning block to guide the positioning block to extend.

[0008] Preferably, a soundproof cover is fitted onto the surface of the driver, and the soundproof cover is located below the grip. The soundproof cover can cooperate with the driver to achieve the purpose of sound insulation.

[0009] Preferably, the soundproof cover contains soundproof cotton, which is placed on the surface of the driver. The soundproof cotton can work in conjunction with the soundproof cover to achieve double soundproofing.

[0010] Preferably, the top of the soundproof cover has an anti-detachment opening, which is fitted onto the surface of the main block. The anti-detachment opening can cooperate with the soundproof cover to achieve the purpose of storing the main block.

[0011] Preferably, the surface of the soundproof cover has a limiting hole, and the positioning block is inserted into the inside of the limiting hole. The limiting hole can cooperate with the soundproof cover and the positioning block to restrict the sliding of the soundproof cover.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a shock-absorbing device, when the worker needs to dampen the brushless motor, the worker places a metal ring on the top of the driver, with the opening of the metal ring fitting onto the anti-rotation block. The worker then installs the driver on the top of the handle. The worker rotates the positioning rod, which extends inside the storage hole and inserts into the insertion hole. When the driver vibrates, the driver presses against the rubber pad on the lower surface of the metal ring, which in turn presses against the metal ring. The metal ring then pushes against the rubber pad on the upper surface, which in turn presses against the handle. The two rubber pads absorb the vibration generated by the driver during operation. By setting a shock-absorbing device, the worker can effectively dampen the brushless motor, preventing loosening at the connection between the brushless motor and the wool shears, thereby reducing the possibility of the wool shears malfunctioning during use.

[0013] In this invention, by setting a noise reduction device, when the worker needs to reduce noise in the driver, the worker puts the soundproof cover on the driver, and the soundproof cover pushes the soundproof cotton onto the driver. The soundproof cover presses down on the soundproof cotton and abuts against the top of the driver. When the soundproof cover slides to the designated position, the worker rotates the positioning block, the positioning block tightens and moves closer to the main block, and the positioning block abuts against the soundproof cover. By setting a noise reduction device, it is possible to effectively reduce noise in the driver, avoid the noise generated by the driver during operation from affecting the worker, and thus protect the worker's hearing.

[0018] In this embodiment: the shock absorption device 3 includes a metal ring 35, which is disposed between the driver 1 and the grip 2. Rubber pads 34 are fixedly connected to both the upper and lower surfaces of the metal ring 35. One rubber pad 34 is placed on the upper surface of the driver 1 and the other rubber pad 34 is placed on the lower surface of the grip 2. A sleeve opening 36 is opened on the surface of the metal ring 35, which is located below the grip 2. An anti-rotation block 37 is fixedly connected to the upper surface of the driver 1. The anti-rotation block 37 is slidably connected to the inner wall of the sleeve opening 36. A connecting assembly is provided on the surface of the grip 2. The connecting assembly includes a socket 33, a positioning rod 32, and a storage hole 31.

[0019] Specifically, the socket 33 is located on the top of the driver 1, and the storage hole 31 is located on the surface of the grip 2. The socket 33 can cooperate with the driver 1 to store the positioning rod 32, and the storage hole 31 can cooperate with the grip 2 to adjust the positioning rod 32.

[0020] Specifically, the internal thread of the receiving hole 31 is connected to a positioning rod 32, which is inserted into the insertion hole 33.

[0021] In this embodiment, the positioning rod 32 can cooperate with the storage hole 31 and the insertion hole 33 to connect the driver 1 and the grip 2 together.

[0022] In this embodiment: a noise reduction device 4 is provided at the top of the driver 1. The noise reduction device 4 includes a main block 43, which is fixedly connected to the top of the driver 1. A positioning block 44 is threadedly connected inside the main block 43. The main block 43 can cooperate with the driver 1 to support the main block 43. The main block 43 can cooperate with the positioning block 44 to guide the positioning block 44 to extend.

[0023] Specifically, a soundproof cover 42 is attached to the surface of the driver 1, and the soundproof cover 42 is located below the grip 2.

[0024] In this embodiment, the soundproof cover 42 can cooperate with the driver 1 to achieve the purpose of sound insulation.

[0025] Specifically, the soundproof cover 42 contains soundproof cotton 41, which is fitted onto the surface of the driver 1. The soundproof cotton 41 can work in conjunction with the soundproof cover 42 to achieve double soundproofing.

[0026] Specifically, the top of the soundproof cover 42 is provided with an anti-detachment opening 45, which is fitted onto the surface of the main block 43.

[0027] In this embodiment, the anti-detachment opening 45 can be used in conjunction with the soundproof cover 42 to achieve the purpose of storing the main block 43.

[0028] Specifically, a limiting hole 46 is provided on the surface of the soundproof cover 42, and the positioning block 44 is inserted into the inside of the limiting hole 46.

Working Principle: By setting up the shock absorption device 3, when the operator needs to dampen the brushless motor, the operator places the metal ring 35 on the top of the driver 1, and the opening 36 on the surface of the metal ring 35 fits onto the anti-rotation block 37. The operator then installs the driver 1 on the top of the handle 2. The operator rotates the positioning rod 32, which extends inside the receiving hole 31 and inserts into the insertion hole 33. When the driver 1 vibrates, it compresses the rubber pad 34 on the lower surface of the metal ring 35, which in turn compresses the metal ring 35. The metal ring 35 pushes the upper surface rubber pad 34 to compress the handle 2. The two rubber pads 34 absorb the vibration generated by the driver 1 during operation. By setting up the shock absorption device 3, the operator can effectively and conveniently dampen the brushless motor. The vibration reduction device prevents loosening at the connection between the brushless motor and the wool shears, thus reducing the likelihood of the wool shears malfunctioning during use. Additionally, by incorporating a noise reduction device 4, when the worker needs to reduce noise in the driver 1, the worker places the soundproof cover 42 onto the driver 1. The soundproof cover 42 pushes the soundproof cotton 41 onto the driver 1, pressing the soundproof cover 42 against the top of the driver 1. When the soundproof cover 42 slides to the designated position, the worker rotates the positioning block 44, which tightens and moves closer to the main block 43, pressing against the soundproof cover 42. By incorporating the noise reduction device 4, the worker can effectively and conveniently reduce noise in the driver 1, preventing the noise generated by the driver 1 during operation from affecting the worker and thus protecting the worker's hearing.
