Technical Field

[0001] The utility model relates to the technical field of hair-pulling devices, in particular to a poultry hair-pulling device. Background Art

[0002] CN219593543U discloses a separable poultry hair-puller, which includes a main body and a chuck assembly detachably installed at the front end of the main body. The inside of the chuck assembly has two obliquely installed hair-pulling shafts. The front ends of the two hair-pulling shafts extend to the outside of the chuck assembly and the distance between them gradually decreases. The rear ends of the two hair-pulling shafts extend into the main body and are connected to the driving mechanism inside the main body, so as to solve the problems in the above background art that the existing hair-puller housing is easily damaged and cannot be used continuously, and replacing a new hair-puller results in high costs.

[0003] For the technical solution disclosed in CN219593543U, after the chuck assembly and its hair-pulling shafts are disassembled as a whole, it is necessary to disassemble the chuck assembly before replacing the hair-pulling shafts, and the operation steps for replacing the hair-pulling shafts are relatively cumbersome. In addition, to disassemble the chuck assembly and its hair-pulling shafts as a whole, a relatively large force is required to separate the two hair-pulling shafts from the coupling at the same time, which is not convenient.

[0004] CN218773272U discloses a hair remover, which is also not convenient for replacing the hair-pulling shafts. Summary of the Utility Model

The housing is provided with a rotary screw hole penetrating through the housing. The hair-pulling shaft locking hole is directly opposite to the rotary screw hole, so that after the coupling rotates, the hair-pulling shaft locking hole can be completely located inside the rotary screw hole.

[0007] The effect achieved by the utility model is that on the premise of ensuring safety, both of the two hair-pulling shafts can be replaced separately, which is relatively convenient.

[0008] A further technical solution is that anti-rotation structures for restricting relative rotation between the end face of the connecting section and the end face of the output end of the rotary driving device are provided.

Specific embodiments

[0030] The following will describe the specific embodiments of the present invention with reference to the drawings in the specification.

[0031] As a specific embodiment, the poultry hair-pulling device of the embodiment of the present invention includes a rotating drive device 2, a machine housing 3, a power supply 9, and two hair-pulling shafts 1 made of metal.

[0032] The two ends of the hair-pulling shaft 1 are respectively a connecting section 11 and a hair-pulling end 19. As shown in the prior art, the hair-pulling shaft 1 is generally cylindrical as a whole, but the hair-pulling end 19 is frustum-shaped or conical. The hair-pulling end 19 is provided with protrusions or grooves evenly distributed around the axis of the hair-pulling shaft 1 to increase the friction of the hair-pulling end 19 against feathers and the like. There is an included angle between the axes of the two hair-pulling shafts 1 to enable the hair-pulling ends 19 of the two hair-pulling shafts 1 to abut or be close to each other. It is easy to understand that for the embodiment where the hair-pulling end 19 is cylindrical, the two hair-pulling shafts 1 are arranged parallel to each other.

[0033] The power supply 9 and the rotating drive device 2 are fixed inside the machine housing 3, and the power supply 9 is electrically connected to the rotating drive device 2. The power supply 9 should be understood in a broad sense, and it can be a battery or a wire for power supply, etc.

[0034] Two coupling shafts 21 are fixedly arranged at the two rotary output ends of the rotary driving device 2, and the coupling shaft 21 is provided with a depilation shaft locking hole 211. Generally, the coupling shaft 21 is also provided with a driving shaft locking hole 219. A rotary screw (not shown in the drawings) is used to make the screw abut against the rotary output end (i.e., the rotary output shaft) of the rotary driving device 2, so that the coupling shaft 21 is fixed to the rotary output end of the rotary driving device 2. The rotary driving device 2 can be two motors, and the motor shafts of the two motors are the two rotary output ends of the rotary driving device 2. It is easy to understand that the rotary driving device 2 can also be shown as in CN218773272U, where the rotary output shaft of one motor is used as the power input to drive the two output shafts of the gearbox to rotate in opposite directions.

[0035] The connecting sections 11 of the two depilation shafts 1 are respectively inserted into the coupling shaft 21, and screws are screwed into the depilation shaft locking holes 211 to abut against the connecting sections 11, so that the connecting sections 11 are fixedly connected to the coupling shaft 21, and the depilation ends 19 of the two depilation shafts 1 abut against or are close to each other. When the rotary driving device 2 rotates, the two depilation shafts 1 can be driven to rotate in opposite directions (i.e., one rotates clockwise and the other rotates counterclockwise) through the coupling shaft 21. A bearing 37 is fixedly arranged in the machine housing 3, and the depilation shaft 1 passes through the bearing 37 to ensure the stability of the depilation shaft 1 during rotation. Since the bearing 37 needs to allow the connecting section 11 to pass through and also needs to maintain the stability of the depilation shaft 1 during rotation, a flexible pad such as a silica gel pad (not marked in the drawings) is fixedly arranged on the inner ring of the bearing 37.

[0036] The machine housing 3 is provided with a rotary screw hole 31 penetrating through the machine housing 3; the depilation shaft locking hole 211 is aligned with the rotary screw hole 31, so that after the coupling shaft 21 rotates, the depilation shaft locking hole 211 can be completely located within the rotary screw hole 31. As Figure 6 shown, when looking along the axis of the rotary screw hole 31 after the coupling shaft 21 rotates, the depilation shaft locking hole 211 is completely located within the rotary screw hole 31.

[0037] The working principle is that when the depilation end 19 is worn or damaged and the depilation shaft 1 needs to be replaced, the coupling shaft 21 is rotated until the depilation shaft locking hole 211 is aligned with the rotary screw hole 31, and then a screwdriver (not shown in the drawings) is used to rotate the screw in the depilation shaft locking hole 211 so that it does not abut against the connecting section 11, and then the connecting section 11 of the depilation shaft 1 can be withdrawn from the coupling shaft 21 to achieve the disassembly of the depilation shaft 1. Conversely, after the depilation shaft 1 passes through the bearing 37 and is inserted into the coupling shaft 21, relying on the frictional force between the connecting section 11 and the coupling shaft 21 to make the coupling shaft 21 rotate after that (usually this action is not required. Because the action of withdrawing the depilation shaft 1 generally does not cause the coupling shaft 21 to rotate around its axis), so that the depilation shaft locking hole 211 is aligned with the rotary screw hole 31, and then the screwdriver can be rotated to fixedly connect the connecting section 11 to the coupling shaft 21. Therefore, the coupling shaft 21 and the screws thereon are located inside the machine housing 3 and cannot come into contact with the human body, so it is relatively safe.

[0038] When the two hair plucking shafts 1 are both fixedly connected to the coupling 21, when a single hair plucking shaft 1 is disassembled and the hair plucking shaft 1 is pulled out, although the other hair plucking shaft 1 will block the extraction of this hair plucking shaft 1, since the hair plucking shaft 1 is made of metal and has elasticity, the hair plucking shaft 1 can be slightly deformed to avoid the extraction of the hair plucking shaft 1. Therefore, compared with CN219593543U, where it is necessary to simultaneously pull out the two hair plucking shafts 1 from the coupling 21, which requires the two hair plucking shafts 1 to simultaneously undergo elastic deformation and requires a large force, the technical solution of the present utility model can realize the individual replacement of the hair plucking shaft 1, and the force required to pull out the hair plucking shaft 1 is smaller and more convenient.

[0039] As can be seen from the above, on the premise of ensuring safety, both of the two hair plucking shafts 1 can be individually replaced, which is more convenient.

[0040] As one of the specific implementation manners, anti-rotation structures (not marked in the attached drawings) for restricting the relative rotation of both are provided on the end face of the connection section 11 and the end face of the output end of the rotary driving device 2. The anti-rotation structure can be a structure such as a rectangular protrusion inserted into a rectangular groove. After the rectangular protrusion is inserted into the rectangular groove, the connection section 11 rotates synchronously with the rotary driving device 2. When the hair plucking shaft locking hole 211 is not aligned with the rotary screw hole 31, it is convenient to adjust the position of the hair plucking shaft locking hole 211 by rotating the output end of the rotary driving device 2 and the coupling 21 through the hair plucking shaft 1.

[0041] As one of the specific implementation manners, it further includes a flexible anti-hair member 4; the anti-hair member 4 is fixedly connected to the machine shell 3 and completely covers the rotary screw hole 31. The anti-hair member 4 is made of silica gel, rubber, or the like. Usually, the anti-hair member 4 completely covers the rotary screw hole 31 and can prevent feathers and the like from entering the machine shell 3 from the rotary screw hole 31 (i.e., has an anti-hair effect); and when it is necessary to replace the hair plucking shaft 1, the anti-hair member 4 is bent to expose the rotary screw hole 31, and then the hair plucking shaft 1 can be replaced as described above.

[0042] As one of the specific implementation manners, the anti-hair member 4 is provided with anti-hair protrusions 41; the anti-hair protrusions 41 are respectively inserted into the rotary screw holes 31. The anti-hair effect can be improved.

[0043] As one of the specific implementation manners, the machine shell 3 is provided with a through connection hole 32, and the middle part of the anti-hair member 4 is provided with a connection protrusion 42; the anti-hair protrusions 41 are respectively located on the connection protrusion 42, and the connection protrusion 42 is inserted into the connection hole 32 and fixedly connected to the machine shell 3. It is convenient for the assembly of the anti-hair member 4.

[0044] As one of the specific embodiments, the connecting protrusion 42 extends outward to form a frustum-shaped connecting flange 421; the end with a larger diameter of the connecting flange 421 abuts or is close to the inner wall of the housing 3. When assembling the anti-hair part 4, the connecting flange 421 is pressed into and passes through the connecting hole 32 until the end with a larger diameter of the connecting flange 421 abuts or is close to the inner wall of the housing 3. This facilitates the assembly of the anti-hair part 4.

[0045] As one of the specific embodiments, the housing 3 includes two half-housings 38 which are detachably connected to each other, for example, by screws.

[0046] As one of the specific embodiments, the housing 3 includes a total length adjustment housing 39. The bearing 37 is fixedly arranged in the total length adjustment housing 39, and the hair-pulling shaft 1 extends out of the total length adjustment housing 39. Generally, the total length adjustment housing 39 is detachable from the half-housing 38, but cannot be pulled out of the half-housing 38 along the direction of the hair-pulling shaft 1. Therefore, it is convenient to replace only the total length adjustment housing 39 to adapt to hair-pulling shafts 1 with different shaft lengths, and the overall length of the housing 3 can be correspondingly changed to improve the feel during use.

[0048] In the present utility model, terms such as a, an, etc. do not represent a limitation of quantity, but represent the existence of at least one of the mentioned objects.

[0050] In the present utility model, terms such as approximately, overall, approximate, close, etc. are limiting terms used to indicate the existence of features but allowing certain deviations. The amount of allowable deviation may vary depending on the specific background; for example, for dimensional deviations, the specific background that can be depended on includes but is not limited to relevant standards of dimensional tolerances.
