In order to reset the rotating seat in this patent document, an exposed tension spring structure is used. When the cutting device works, a large number of dust particles will be generated. The exposed tension spring is easy to collide with other objects. In addition, the tension spring is prone to dust accumulation, which affects the reliable operation of the tension spring. Content of the Utility Model

[0003] The utility model aims at the above problems and provides a cutting mechanism and a cutting device.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A cutting mechanism, comprising:

[0006] A mounting seat having a fixing plate;

[0007] A motor mounted on the mounting seat;

[0008] A rotating seat rotatably mounted on the mounting seat or the housing of the motor. The rotating seat has an initial working position. In the initial working position, the rotating member is located at an upper position;

[0009] A rotating member rotatably arranged on the rotating seat. A cutting blade is to be mounted on the rotating member, and the motor is used to drive the rotating member to rotate;

[0010] A fixing member for connecting the fixing plate and the rotating seat to relatively fix the fixing plate and the rotating seat;

[0011] A torsion spring having a body and two fixed ends. The torsion spring is hidden between the fixing plate and the rotating seat. One fixed end of the torsion spring is connected to the fixing plate, and the other fixed end is connected to the rotating seat; after the fixing member is loosened, the torsion spring is used to rotate the rotating seat to the initial working position.

[0012] In this application, the torsion spring is hidden between the fixing plate and the rotating seat and is no longer exposed, solving the problems caused by the external placement of the existing tension spring.

[0013] In one embodiment of the utility model, the rotation axis of the output shaft of the motor coincides with the rotation axis of the rotating seat;

[0014] The rotating seat has an operating handle.

[0015] The operating handle facilitates changing the rotation angle of the rotating seat.

[0016] In one embodiment of the present utility model, the motor drives the rotating member to rotate through a transmission structure.

Detailed Description of the Preferred Embodiments

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0041] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "inner" and "outer" is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, terms such as "first" and "second" are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0042] In the description of the present application, it should also be noted that unless otherwise clearly specified and defined, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0043] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0044] As Figures 1 - 4 shown, this embodiment discloses a cutting device, including:

[0045] A cutting seat 1, having a chute 11;

[0046] A water receiving box 3, slidably arranged on the chute 11 of the cutting seat 1, for receiving the water flowing down from the cutting seat 1.

[0047] In this application, the water receiving box 3 is directly slidably installed below the cutting seat 1. Compared with the prior art, the distance between the water receiving box 3 and the cutting seat 1 is very close, and there is no problem of a large amount of water splashing out. Moreover, when replacing the water for cutting, only the water receiving box 3 needs to be removed, and the whole operation is convenient and reliable.

[0048] As Figure 3 shown, in this embodiment, there are two groups of chutes 11. The two groups of chutes 11 are located at the lower part of the cutting seat 1 and are arranged in parallel at intervals. The outer side of the water receiving box 3 has a handle 31; the left and right sides of the water receiving box 3 have sliders 32 that cooperate with the corresponding group of chutes 11.

[0049] As Figure 1 shown, in this embodiment, the cutting seat 1 has a supporting part 12 and a vacant part 13 located on one side of the supporting part 12. The water receiving box 3 is located below the vacant part 13, and the water flows through the supporting part 12 and then flows into the water receiving box 3 through the vacant part 13.

[0050] This setting facilitates that when the cutting device is working, the sprayed water finally flows into the vacant part 13 through the supporting part 12 and then all flows into the water receiving box 3.

[0051] During cutting, a large amount of dust particles will be generated. The water flowing from the cutting device into the water basin contains more impurities, which will affect the long-term reliable operation of the water pump. In addition, when the water containing a large amount of dust particles is sprayed onto the blade, the cooling efficiency will be reduced compared with pure water. To address the above problems, as Figure 1 and 4 shown, in this embodiment, the water receiving box 3 has a water receiving groove 33, a filtering groove 34, and a water supply groove 35 arranged in sequence:

[0052] The water receiving groove 33 is used to receive the water flowing from the cutting seat 1;

[0053] The filtering groove 34 has a precipitation part 341 and a communication part 342. The precipitation part 341 is communicated with the water receiving groove 33. When the water in the precipitation part 341 overflows, it flows into the communication part 342. The bottom of the side wall of the communication part 342 has a communication port 3421;

[0054] As shown, the water supply groove 35 is communicated with the communication port 3421 of the filtering groove 34.

[0055] The bottom of the precipitation part 341 can precipitate a large amount of particulate matter (under the action of gravity, the particulate matter is borne below), and the relatively clean upper part flows into the communication part 342 after overflow, and finally enters the water supply groove 35 through the communication port 3421 and is finally pumped out by the water supply pump.

[0056] In actual use, there can be multiple precipitation parts 341. At this time, the precipitation parts 341 are arranged in sequence, the highest water level of the previous precipitation part 341 is greater than or equal to the highest water level of the next precipitation part 341. After the last precipitation part 341 reaches the highest water level, the water overflows and flows into the communication part 342.

[0057] The water from the water receiving groove 33 can be reliably filtered and purified through multiple precipitation tanks.

[0058] In this embodiment, there are multiple filtering grooves 34. The filtering grooves 34 are arranged in sequence. The communication part 342 of the previous filtering groove 34 is communicated with the first precipitation part 341 of the next filtering groove 34 through the communication port 3421. As Figure 4 shown, there are 2 filtering grooves 34 in this embodiment.

[0059] In this embodiment, the water supply groove 35 is used to install the water pump.

[0060] As Figure 3 and 4 shown, in this embodiment, the bottom of the water supply groove 35 has a water supply port 351.

[0061] As Figure 4 shown, in this embodiment, the water receiving tank 33 has a first part 331 and a second part 332 arranged in sequence. The first part 331 and the second part 332 are directly communicated. The bottom wall of the second part 332 is lower than the bottom wall of the first part 331. The second part 332 has a water outlet 3321. The second part 332 is communicated with the first sedimentation part 341 of the first filter tank 34 through the water outlet 3321;

[0062] The bottom of the water outlet 3321 extends to the bottom of the sedimentation part 341, or the bottom of the water outlet 3321 extends to the bottom of the second part 332.

[0063] As Figure 1 and 5 shown, the cutting device of this embodiment further includes:

[0064] A cross beam 2, located above the mounting seat 4;

[0065] A mounting seat 4, having a fixing plate 41, and the mounting seat 4 is movably arranged on the cross beam 2;

[0066] A motor 5, mounted on the mounting seat 4;

[0067] A rotating seat 6, rotatably mounted on the mounting seat 4 or the housing of the motor 5. The rotating seat 6 has an initial working position. In the initial working position, the rotating member 61 is located at an upper position;

[0068] A rotating member 61, rotatably arranged on the rotating seat 6. A cutting blade 62 is to be mounted on the rotating member 61, and the motor 5 is used to drive the rotating member 61 to rotate;

[0069] A fixing member 63, used to connect the fixing plate 41 and the rotating seat 6 to relatively fix the fixing plate 41 and the rotating seat 6;

[0070] A torsion spring 7, having a body 71 and two fixed ends 72. The torsion spring 7 is hidden and arranged between the fixing plate 41 and the rotating seat 6. One fixed end 72 of the torsion spring 7 is connected to the fixing plate 41, and the other fixed end 72 is connected to the rotating seat 6; after the fixing member 63 is loosened, the torsion spring 7 is used to rotate the rotating seat 6 to the initial working position.

[0071] In this application, the torsion spring 7 is hidden and arranged between the fixing plate 41 and the rotating seat 6 and is no longer exposed, solving the problems caused by the existing external tension spring.

[0072] In this embodiment, the rotation axis of the output shaft of the motor 5 coincides with the rotation axis of the rotating seat 6.

[0073] As Figure 1As shown, in this embodiment, the rotating seat 6 has an operating handle 64. The operating handle 64 facilitates changing the rotation angle of the rotating seat 6.

[0074] As Figure 5 shown, in this embodiment, the motor 5 drives the rotating member 61 to rotate through the transmission structure 8. The transmission structure 8 can be in various forms, including but not limited to a transmission belt, a gear set, and the like.

[0075] As Figure 5 shown, in this embodiment, a threaded hole (not marked in the figure) is provided on the fixing plate 41. The fixing plate 41 also has a first arc-shaped hole 411 arranged around the rotation axis of the rotating seat 6. The fixing member 63 passes through the first arc-shaped hole 411 and is in threaded cooperation with the threaded hole. The provision of the threaded hole on the fixing plate 41 of the present application means that it can be directly provided or achieved by installing a nut.

[0076] As Figure 1 and 6 shown, in this embodiment, a protective cover 65 is also rotatably mounted on the rotating seat 6. The protective cover 65 is used to cover the cutting blade 62.

[0077] Since the rotating seat 6 can change the angle, the rotatable design of the protective cover 65 facilitates adapting to the angle of the rotating seat 6, making the cutting work safer.

[0078] As Figure 6 shown, in this embodiment, the protective cover 65 has a second arc-shaped hole 66 arranged around the rotation axis of the rotating member 61. The protective cover 65 is connected to the rotating seat 6 through a fastener (omitted and not shown in the figure) passing through the second arc-shaped hole 66.

[0079] In actual use, a spring can be sleeved on the fastener. One side of the spring cooperates with the mounting seat 4, and the other side cooperates with the protective cover 65. The spring enables the protective cover 65 to have a self-positioning function.

[0080] As Figure 1 、 7 and 8 shown, the cutting device further includes a control mechanism. The control mechanism includes a fixed box 91 and an operation box 92. The operation box 92 is rotatably arranged on the fixed box 91.

[0081] The rotatable operation box 92 can facilitate the operator to adjust the angle as needed, making the operation more convenient.

[0082] As Figure 8 shown, in this embodiment, among the fixed box 91 and the operation box 92, one of them has an arc-shaped part 921, and the other has a convex block 911. The convex block 911 moves in the arc-shaped part 921, and the arc-shaped part 921 defines the rotatable angle of the operation box 92.

[0083] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent protection scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, directly or indirectly applied in other related technical fields, shall be included in the protection scope of the present utility model by the same token.
