[0017] The beneficial effects achieved by adopting the above technical solution are as follows:

[0018] This utility model discloses a poultry whole leg cutting machine, which includes a frame, a racetrack-shaped track fixed to the top of the frame, multiple leg-hanging mechanisms slidably mounted on the racetrack-shaped track, a chain conveying mechanism for driving the multiple leg-hanging mechanisms to run along the racetrack-shaped track, and a cutting device located below a straight track section on one side of the racetrack-shaped track. A tension adjustment mechanism is provided between the frame and the driven sprocket of the chain conveying mechanism. The tension adjustment mechanism includes an adjustment frame fixed to the frame, a slide block slidably mounted on the adjustment frame along the direction of approaching / away from the driving sprocket of the chain conveying mechanism, an elastic structure for driving the slide block to slide away from the driving sprocket, a lead screw rotatably mounted on the adjustment frame, and an adjustment wheel fixed to the end of the lead screw away from the driving sprocket. The lead screw is threadedly connected to the slide block, and the driven sprocket is rotatably mounted on the slide block.

[0019] The dividing device includes a dividing conveyor chain mechanism arranged along the extension direction of the straight track section, multiple leg clamping mechanisms spaced apart on the outer periphery of the dividing conveyor chain mechanism, a pushing structure for pushing the leg clamping mechanisms to clamp, and a dividing mechanism arranged above the dividing conveyor chain mechanism. One end of the dividing conveyor chain mechanism is set as the inlet end and the other end is set as the outlet end.

[0020] The poultry leg splitting machine also includes a splitting detection unit located on the feed end side of the splitting mechanism near the splitting conveyor chain mechanism for detecting the leg-holding mechanism, a discharge plate located on the discharge end side of the splitting conveyor chain mechanism and fixed to the frame, a counting detection unit located on the splitting mechanism, and an electrical control box fixed to the frame. The running chain conveyor mechanism, the splitting conveyor chain mechanism, the splitting mechanism, the splitting detection unit, and the counting detection unit are all electrically connected to the electrical control box.

[0021] When splitting poultry legs, the operator places the flank of the poultry leg onto the U-shaped hook of the leg-hanging mechanism on the side of the machine frame away from the splitting device, thus suspending the poultry leg in the leg-hanging mechanism. A drive motor drives a drive sprocket to rotate, which in turn drives multiple leg-hanging mechanisms along a racetrack-shaped track via a drive chain, conveying the poultry leg to the splitting conveyor chain mechanism. After the leg-holding mechanism holds the poultry leg tightly, the splitting conveyor chain mechanism drives the holding mechanism to move. As the leg passes the splitting mechanism, the splitting mechanism separates the upper leg from the flank. The poultry leg is cut off, the upper leg falls off, and the flank leg is suspended by the U-shaped hook of the leg hanging mechanism. The chain conveyor drives the leg hanging mechanism to move to the unloading plate. Under the movement of the leg hanging mechanism and the limitation of the unloading plate, the flank leg is pushed upward to disengage from the U-shaped hook of the leg hanging mechanism. The entire cutting process only requires the operator to suspend the poultry leg on the leg hanging mechanism to complete the feeding operation of the poultry leg. The poultry leg is cut by the poultry leg cutting machine, which can improve the consistency of the cutting of the upper leg and the flank leg and the production efficiency, and can also reduce the labor intensity of the operator.

[0022] Meanwhile, since the slide block is slidably mounted on the adjusting frame, the driven sprocket is rotatably mounted on the slide block, and the screw is threadedly connected to the slide block, rotating the adjusting wheel can adjust the position of the slide block, thereby adjusting the position of the driven sprocket, so that the running chain is in a taut state. Furthermore, the elastic structure can drive the slide block to slide away from the driving sprocket, preventing the slide block from sliding towards the driving sprocket. This avoids the running chain from becoming loose and affecting the conveying accuracy of the running chain conveying mechanism, and can further improve the consistency of segmentation.

[0023] This invention provides a poultry whole leg cutting machine that solves the problems of poor cutting consistency and low production efficiency caused by manual cutting of poultry whole legs, such as the upper leg and the flank leg. It also reduces labor intensity. Attached Figure Description

[0038] like Figures 1 to 10 As shown, the poultry whole leg splitting machine of this utility model is used to split the upper leg and the flank leg of poultry whole legs. It includes a frame 10, a racetrack-shaped track 20 fixed to the top of the frame 10, multiple leg hanging mechanisms 30 slidably installed on the racetrack-shaped track 20, a running chain conveying mechanism 40 for driving the multiple leg hanging mechanisms 30 to run along the racetrack-shaped track 20, and a splitting device set below a straight track section on one side of the racetrack-shaped track 20.

[0039] The chain conveyor mechanism 40 includes a drive sprocket 41 rotatably mounted on the frame 10 and positioned on an arc-shaped track section at one end of the racetrack 20; a drive motor for driving the drive sprocket 41; a driven sprocket 42 rotatably mounted on an arc-shaped track section at the other end of the racetrack 20; and a chain 43 surrounding the drive sprocket 41 and the driven sprocket 42. Multiple leg-mounting mechanisms 30 are fixedly connected to the chain 43. A tension adjustment mechanism is provided between the frame 10 and the driven sprocket 42. The tension adjustment mechanism includes a chain corresponding to the driven sprocket 42 and fixed to the frame 10. The frame 10 includes an adjusting frame 44, a slide block 45 slidably mounted on the adjusting frame 44 in the direction of approaching / away from the operating drive sprocket 41, an elastic structure 48 for driving the slide block 45 to slide away from the operating drive sprocket 41, a lead screw 46 rotatably mounted on the adjusting frame 44 in the direction of the interval between the operating drive sprocket 41 and the operating driven sprocket 42, and an adjusting wheel 47 fixed at the end of the lead screw 46 away from the operating drive sprocket 41. The lead screw 46 is threadedly connected to the slide block 45, and the operating driven sprocket 42 is rotatably mounted on the slide block 45. Alternatively, a nut slider can be mounted on the lead screw 46 and fixedly connected to the slide block 45.

[0040] The dividing device includes a dividing conveyor chain mechanism 50 arranged along the extension direction of the straight track section, a plurality of leg-holding mechanisms 60 spaced apart on the outer periphery of the dividing conveyor chain 54 of the dividing conveyor chain mechanism 50, a pushing structure for pushing the leg-holding mechanisms 60 to hold tightly, and a dividing mechanism 70 arranged above the dividing conveyor chain mechanism 50. One end of the dividing conveyor chain mechanism 50 is set as the inlet end and the other end is set as the outlet end.

[0041] It also includes a segmentation detection unit 81 located on the feed end side of the segmentation mechanism 70 near the segmentation conveyor chain mechanism 50 for detecting the leg clamping mechanism 60, a discharge plate 12 located on the discharge end side of the segmentation conveyor chain mechanism 50 and fixed to the frame 10, a counting detection unit 82 located on the segmentation mechanism 70, and an electrical control box 83 fixed to the frame 10. The drive motor, segmentation conveyor chain mechanism 50, segmentation mechanism 70, segmentation detection unit 81, and counting detection unit 82 are electrically connected to the electrical control box 83. Typically, the segmentation detection unit 81 and the counting detection unit 82 are detection sensors.

[0042] When cutting poultry legs, the operator places the flank of the poultry leg onto the U-shaped hook 321 of the leg-hanging mechanism 30 on the side of the frame 10 away from the cutting device, thus suspending the poultry leg on the leg-hanging mechanism 30. The drive motor drives the drive sprocket 41 to rotate, which drives multiple leg-hanging mechanisms 30 to run along the racetrack-shaped track 20 via the drive chain 43, conveying the poultry leg to the cutting conveyor chain mechanism 50. After the leg-holding mechanism 60 holds the poultry leg tightly, the cutting conveyor chain mechanism 50 drives the leg-holding mechanism 60 to move. When passing the cutting mechanism 70, the cutting mechanism 70 separates the upper leg and flank of the poultry leg. The upper leg is cut off and falls off. The flank leg is suspended by the U-shaped hook 321 of the leg hanging mechanism 30. The chain conveyor mechanism 40 drives the leg hanging mechanism 30 to move to the unloading plate 12. Under the movement of the leg hanging mechanism 30 and the limitation of the unloading plate 12, the flank leg is pushed upward to disengage from the U-shaped hook 321 of the leg hanging mechanism 30. The entire splitting process only requires the operator to suspend the poultry whole leg on the leg hanging mechanism 30 to complete the feeding operation of the poultry whole leg. The poultry whole leg is split by the poultry whole leg splitting machine, which can improve the splitting consistency between the upper leg and the flank leg and the production efficiency, and can also reduce the labor intensity of the operator.

[0043] Meanwhile, since the slide block 45 is slidably mounted on the adjusting frame 44, the driven sprocket 42 is rotatably mounted on the slide block 45, and the lead screw 46 is threadedly connected to the slide block 45, rotating the adjusting wheel 47 can adjust the position of the slide block 45, thereby adjusting the position of the driven sprocket 42, so that the running chain 43 is in a tensioned state. Furthermore, the elastic structure 48 can drive the slide block 45 to slide away from the driving sprocket 41, which can prevent the slide block 45 from sliding towards the driving sprocket 41, thus avoiding the running chain 43 from becoming loose and affecting the conveying accuracy of the running chain conveying mechanism 40, and further improving the consistency of the division.

[0044] This invention provides a poultry whole leg cutting machine that solves the problems of poor cutting consistency and low production efficiency caused by manual cutting of poultry whole legs, such as the upper leg and the flank leg. It also reduces labor intensity.

[0045] In this utility model, in order to facilitate the installation of the driven sprocket 42, a support arm 49 is provided below the slide 45 in a horizontal direction. A connecting arm is provided between one end of the support arm 49 and the slide 45, and the driven sprocket 42 is rotatably installed at the other end of the support arm 49.

[0046] Specifically, the adjustment frame 44 includes a square frame, a fixed crossbeam 441 fixed between the proximal side of the square frame near the drive sprocket 41 and the distal side of the square frame away from the drive sprocket 41, and a slide block 45 disposed between the fixed crossbeam 441 and the distal side; two parallel guide rods are connected between the proximal side and the distal side, and the slide block 45 is slidably connected to the two guide rods respectively.

[0047] Furthermore, the lead screw 46 is positioned between the two guide rods. Typically, the elastic structure 48 is a spring fitted onto the lead screw 46 between the fixed crossbeam 441 and the slide block 45.

[0048] In this invention, the inner side of the racetrack-shaped track 20 is provided with an inner slide rail, and the outer side of the racetrack-shaped track 20 is provided with an outer slide rail. Specifically, the racetrack-shaped track 20 includes a racetrack-shaped vertical plate ring and a racetrack-shaped flat plate ring fixed to the bottom side of the vertical plate ring. An inner slide rail is formed between the inner side of the vertical plate ring and the corresponding flat plate ring, and an outer slide rail is formed between the outer side of the vertical plate ring and the corresponding flat plate ring. Of course, the racetrack-shaped track 20 can also be configured as follows: it includes a track body, the inner side of the track body is provided with an inner ring groove, and the outer side of the track body is provided with an outer ring groove. The inner ring groove forms the inner slide rail, and the outer ring groove forms the outer slide rail.

[0049] like Figure 3 As shown, the leg-hanging mechanism 30 includes a leg-hanging seat 31 and a hook 32 fixed to the leg-hanging seat 31. The hook 32 is provided with a U-shaped hook 321, on which the flank of the poultry's entire leg is hung. It also includes a first roller bracket 33a and a second roller bracket 33b respectively rotatably mounted on the leg-hanging seat 31. The rotation axes of the first roller bracket 33a and the second roller bracket 33b are arranged vertically and parallel to each other. A first inner roller 34a and a first outer roller are rotatably mounted on the upper part of the first roller bracket 33a. 35a, the rotation axes of the first inner roller 34a and the first outer roller 35a are perpendicular to the rotation axis of the first roller bracket 33a. The second inner roller 34b and the second outer roller 35b are rotatably mounted on the upper part of the second roller bracket 33b. The rotation axes of the second inner roller 34b and the second outer roller 35b are perpendicular to the rotation axis of the second roller bracket 33b. The first inner roller 34a and the second inner roller 34b are slidably mounted on the inner slide rail, and the first outer roller 35a and the second outer roller 35b are slidably mounted on the outer slide rail.

[0050] Since the two ends of the runway-shaped track 20 are respectively provided with arc-shaped track sections, the first roller bracket 33a and the second roller bracket 33b are rotatably installed on the leg support body 31. The first roller bracket 33a and the second roller bracket 33b can rotate accordingly in the arc-shaped track section, which is convenient to adapt to the arc-shaped track section and enables the leg support mechanism 30 to slide more smoothly along the arc-shaped track section of the runway-shaped track 20.

[0051] Specifically, the first roller bracket 33a and the second roller bracket 33b each include a mounting base 331 rotatably mounted on the leg seat 31, and a frame 332 rotatably mounted on the mounting base 331. The rotation axis of the frame 332 is perpendicular to the rotation axis of the mounting base 331. The upper part of the frame 332 is provided with two mounting ears spaced apart along the rotation axis of the frame 332. The first inner roller 34a and the first outer roller 35a are rotatably mounted on the two mounting ears of the frame 332 of the first roller bracket 33a, and the rotation axes of the first inner roller 34a and the first outer roller 35a are parallel to the rotation axis of the frame 332 of the first roller bracket 33a. The second inner roller 34b and the second outer roller 35b are rotatably mounted on the two mounting ears of the frame 332 of the second roller bracket 33b, and the rotation axes of the second inner roller 34b and the second outer roller 35b are parallel to the rotation axis of the frame 332 of the second roller bracket 33b.

[0052] To further improve the segmentation efficiency, the hook 32 includes a connecting rod fixed to the leg-hanging seat 31, with U-shaped hooks 321 on opposite sides of the connecting rod. Each hook 32 can hang two whole poultry legs. Correspondingly, the first roller bracket 33a and the second roller bracket 33b are respectively arranged on opposite sides of the connecting rod, which can make the sliding of the leg-hanging mechanism 30 more stable.

[0053] In this utility model, in order to facilitate installation and fixation, a mounting bracket 15 corresponding to the dividing device is fixed on the frame 10, and the dividing device is mounted on the mounting bracket 15.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, the segmented conveyor chain mechanism 50 includes a segmented conveyor drive sprocket 51 and a segmented conveyor driven sprocket 53 spaced apart along the extension direction of the straight track section, a segmented conveyor chain 54 surrounding the segmented conveyor drive sprocket 51 and the segmented conveyor driven sprocket 53, and a segmented conveyor motor 52 for driving the segmented conveyor drive sprocket 51 to rotate. Multiple leg-holding mechanisms 60 are arranged sequentially at intervals along the circumference of the segmented conveyor chain 54 and are respectively fixed to the outer periphery of the segmented conveyor chain 54.

[0055] like Figure 7 and Figure 8As shown, the leg-holding mechanism 60 includes a leg-holding seat 61 fixed to the segmented conveyor chain 54 of the segmented conveyor chain mechanism 50. A limiting plate structure 62 and a roller structure 63 are respectively provided and rotatably mounted on the leg-holding seat 61, corresponding to the inner and outer sides of the straight track section. Magnet structures are respectively provided between the limiting plate structure 62 and the leg-holding seat 61, and between the roller structure 63 and the leg-holding seat 61. The magnet structure between the limiting plate structure 62 and the leg-holding seat 61 is used to push the limiting plate structure 62 to flip inwards towards the inner side of the straight track section, and the magnet structure between the roller structure 63 and the leg-holding seat 61 is used to push the roller structure 63 to flip outwards towards the outer side of the straight track section. Figure 8 As shown, the magnet structure includes a first magnet 64 fixed to the leg support body 61 and a second magnet 65 fixed to the limiting plate structure 62 / roller structure 63. The first magnet 64 and the second magnet 65 have the same magnetic polarity. The repulsive force between the first magnet 64 and the second magnet 65 pushes the limiting plate structure 62 to flip inward to the inside of the straight track section and the roller structure 63 to flip outward to the outside of the straight track section.

[0056] Specifically, the limiting plate structure 62 includes a limiting plate hinge seat 621 rotatably mounted on the leg-holding seat 61, a connecting plate 622 fixed to the limiting plate hinge seat 621, and an upper limiting plate 623 and a lower limiting plate 624 fixed to the side of the connecting plate 622 near the roller structure 63. The upper limiting plate 623 and the lower limiting plate 624 are spaced apart along the direction of approaching / moving away from the limiting plate hinge seat 621. The distance between the outer side of the upper limiting plate 623 away from the connecting plate 622 and the connecting plate 622 is less than the distance between the outer side of the lower limiting plate 624 away from the connecting plate 622 and the connecting plate 622. An upper leg-holding groove is provided on the outer side of the upper limiting plate 623, and a lower leg-holding groove is provided on the outer side of the lower limiting plate 624.

[0057] The roller clamping structure 63 includes a roller clamping hinge seat 631 rotatably mounted on the clamping leg seat 61, a roller clamping bracket 632 fixed to the roller clamping hinge seat 631, and a roller clamping 633 rotatably mounted on the roller clamping bracket 632. The roller clamping 633 is correspondingly arranged with the upper clamping leg groove and the lower clamping leg groove and is arranged between the lower limiting plate 624 and the limiting plate hinge seat 621.

[0058] The pushing structure includes a first leg-holding guide rod 67 disposed on the inner side of the corresponding straight track section for pushing the limiting plate structure 62 to rotate outward of the straight track section, and a second leg-holding guide rod 68 disposed on the outer side of the corresponding straight track section for pushing the roller-holding structure 63 to rotate inward of the straight track section. Specifically, the first leg-holding guide rod 67 and the second leg-holding guide rod 68 each include a straight rod body and arc-shaped rod bodies disposed at both ends of the straight rod body. The arc-shaped rod body of the first leg-holding guide rod 67 bends downward and deflects inward of the straight track section, and the arc-shaped rod body of the second leg-holding guide rod 68 bends downward and deflects outward of the straight track section.

[0059] To facilitate the rotation of the limiting plate structure 62 to the outer side of the straight track section and the rotation of the clamping roller structure 63 to the inner side of the straight track section, the limiting plate structure 62 further includes a first rotating roller 625 rotatably mounted on the side of the connecting plate 622 away from the clamping roller structure 63, and the clamping roller structure 63 further includes a second rotating roller 634 rotatably mounted on the side of the clamping roller bracket 632 away from the limiting plate structure 62. Furthermore, two first rotating rollers 625 are spaced apart along the straight rod of the first clamping leg guide rod 67, and two second rotating rollers 634 are spaced apart along the straight rod of the second clamping leg guide rod 68.

[0060] Furthermore, the leg-holding mechanism 60 also includes a receiving tray 66 fixed to the leg-holding seat 61. When the limiting plate structure 62 and the roller structure 63 are engaged, the receiving tray 66 is located below the upper leg-holding groove, the lower leg-holding groove, and the roller 633, and is used to support the upper leg under the division.

[0061] To improve cutting efficiency, two upper leg-holding grooves are spaced apart on the upper limit plate 623 of the limiting plate structure 62, and two lower leg grooves are spaced apart on the lower limit plate 624. Correspondingly, two holding rollers 633 are spaced apart on the holding roller bracket 632 of the holding roller structure 63. In this way, two whole poultry legs can be suspended on each leg hanging mechanism 30, and each leg holding mechanism 60 can hold two whole poultry legs at the same time. When the more than 40 leg hanging mechanisms 30 run one revolution along the racetrack-shaped track 20 in the running chain conveyor mechanism, the number of whole poultry legs that can be cut can be doubled, which can greatly improve production efficiency.

[0062] like Figure 4 , Figure 5 and Figure 6 As shown, for ease of adjustment, the dividing device also includes a support frame 57 slidably mounted vertically on the mounting frame 15, a height adjustment mechanism 55 fixed to the mounting frame 15 for driving the support frame 57 to rise and fall, a dividing conveyor chain mechanism 50 slidably mounted on the support frame 57 in the direction of approaching / moving away from the frame 10, and a translation adjustment mechanism 56 provided between the support frame 57 and the dividing conveyor chain mechanism 50; a push structure is fixed to the dividing conveyor chain mechanism 50, that is, the first leg guide rod 67 and the second leg guide rod 68 are respectively fixed to the dividing conveyor chain mechanism 50, and the dividing mechanism 70 is fixed to the support frame 57. To enhance the adjustment effect, two sets of height adjustment mechanisms 55 are spaced apart along the extension direction of the straight track section. Typically, the height adjustment mechanism 55 is a worm gear screw jack, but it can also be an electric cylinder. Correspondingly, two sets of translation adjustment mechanisms 56 are spaced apart along the extension direction of the straight track section. Typically, the translation adjustment mechanism 56 is a screw nut mechanism, but it can also be an electric cylinder.

[0063] In this invention, the dividing mechanism 70 includes a dividing bracket fixed to the support frame 57, a pre-cutting blade 71 fixed to the dividing bracket and arranged along the extension direction of the straight track section, the pre-cutting blade 71 having a pre-cutting edge on one side corresponding to the feed end of the dividing conveyor chain mechanism 50, and also includes a dividing motor 72 fixed to the dividing bracket and a dividing circular blade 73 fixed to the output shaft of the dividing motor 72, the dividing circular blade 73 being arranged behind the pre-cutting edge of the pre-cutting blade 71. The pre-cutting blade 71 pre-cuts from the bone suture between the upper leg and the hind leg of the poultry, widening the bone suture, and then the dividing circular blade 73 divides it. At the same time, the pre-cutting blade 71 can widen the cut, making it easier for the dividing circular blade 73 to cut the upper leg and the hind leg of the poultry.

[0064] Specifically, the pre-cutting blade 71 has a stepped portion 711 on the side near the feed end of the dividing conveyor chain mechanism 50. The stepped portion 711 divides the pre-cutting blade 71 into a front blade body and a rear blade body. The rear blade body protrudes upward or downward from the front blade body. The dividing circular blade 73 is set corresponding to the rear blade body, and the dividing circular blade 73 is flush with the cutting edge of the pre-cutting blade on the side of the feed end of the dividing conveyor chain mechanism 50. The stepped portion 711 can further enlarge the bone gap, making it easier for the dividing circular blade 73 to divide the whole leg of poultry from the opening cut by the pre-cutting blade 71.

[0065] To prevent the poultry legs held by the limiting plate structure 62 and the holding roller structure 63 from moving towards / away from the frame 10 during the segmentation of poultry legs, a segmentation pressure rod 74 is provided above the leg holding mechanism 60 on the upper side of the segmentation conveyor chain mechanism 50, which is arranged along the extension direction of the straight track section. This rod is used to press the poultry legs. Specifically, the segmentation pressure rod 74 is fixedly connected to the segmentation conveyor chain mechanism 50.

[0066] In this utility model, in order to facilitate the precise clamping of the poultry's legs suspended on the leg-holding mechanism 30 by the limiting plate structure 62 and the clamping roller structure 63 of the leg-holding mechanism 60, a hook guide bar 11 fixed to the frame 10 is provided below the straight track section on the side corresponding to the dividing device of the racetrack-shaped track 20. The end of the hook guide bar 11 is provided with a guide slope, which can prevent the end of the hook guide bar 11 from affecting the operation of the leg-holding mechanism 30.

[0067] like Figure 2 and Figure 9 As shown, the unloading plate 12 includes a straight section plate and an inclined section plate connected to the rear side of the straight section plate and extending upward at an incline. The leg-hanging mechanism 30 operates along the racetrack-shaped track 20. The flanks of the poultry's whole legs and the U-shaped hooks 321 of the leg-hanging mechanism 30 move to both sides of the straight section plate. As the leg-hanging mechanism 30 moves, under the constraint of the inclined section plate, it can push the flanks of the poultry's whole legs to move upward and thus disengage from the U-shaped hooks 321.

[0068] Specifically, in order to ensure that the flanks of poultry can be smoothly detached from the U-shaped hook 321, a discharge block 13 is provided at the discharge end of the segmented conveyor chain mechanism 50, which is spaced apart from the hook guide bar 11. The discharge block 13 is fixed to the frame 10.

[0069] In this invention, in order to improve the accuracy of counting, the counting detection unit 82 is set on the side of the dividing mechanism 70 near the feed end of the dividing conveyor chain mechanism 50. A detection pressure block 14 corresponding to the counting detection unit 82 is fixed on the frame 10 to limit the leg hanging mechanism 30 that runs to the counting detection unit 82, so as to prevent the leg hanging mechanism 30 from shaking and affecting the accuracy of counting.

[0070] In this invention, a roller brush mechanism 90 is provided on the outer side of the feed end of the segmented conveyor chain mechanism 50, which is used to turn the skin and meat of the whole leg of poultry upward, thereby increasing the amount of skin and meat on the drumstick of the whole leg of poultry.

[0071] Specifically, the roller brush mechanism 90 includes a roller body arranged along the extension direction of the straight track section, the roller body is provided with hard bristles, and a roller brush drive motor for driving the roller body to rotate. The roller brush mechanism 90 is fixed to the frame 10.

[0072] The above description is only some embodiments of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
