DETAILED DESCRIPTION

[0031] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides an ultra-fine grinding electric shredder, comprising: Branch chipper housing 1; The bearing assembly 2 is arranged at the front end of the shell 1 of the branch chipper; The fourth rotating shaft 9 is rotatably disposed above the discharge end of the bearing assembly 2; The pressure roller 3 is mounted on the fourth rotating shaft 9; The third rotating shaft 6 is arranged on a side of the pressing roller 3 away from the bearing assembly 2 and is rotatably connected to the shell 1 of the shredder; A crushing roller 5 is mounted on the third rotating shaft 6; The arc-shaped crushing net 7 is fixedly connected to the inner wall of the shredder housing 1 and is located below the crushing roller 5; A discharging device is arranged below the arc-shaped crushing net 7; A spline shaft 13, coaxially and fixedly connected to one end of the third rotating shaft 6; The speed regulating disc 12 is slidably arranged on the spline shaft 13 and is symmetrically distributed; The reset assembly 14 is used to elastically support the outer side of the speed regulating disc 12; The belt 11 is sleeved at one end between two speed regulating discs 12. The cross section of the belt 11 is an isosceles trapezoid and fits with the inner side of the speed regulating disc 12 through an inclined surface. Fig.13 As shown; The diameter adjusting disk 10 is connected to the fourth rotating shaft 9 and is connected to an end of the belt 11 away from the speed adjusting disk 12; The sliders 20 are slidably disposed on both sides of the shredder housing 1 and are rotatably connected to the fourth rotating shaft 9; The arc-shaped slide grooves 19 are provided on both sides of the shell 1 of the branch shredder and are slidably matched with the slide block 20; The driving device 21 is used to drive the fourth rotating shaft 9 to rotate.

[0033] In the embodiment of the present invention, a branch is placed on the carrying component 2, and the carrying component 2 drives the branch to move under the pressure roller 3. The protrusion on the pressure roller 3 is stuck in the branch, causing the pressure roller 3 to lift, and the driving device 21 drives the fourth rotating shaft 9 to rotate, and the fourth rotating shaft 9 drives the pressure roller 3 to rotate to transport the branch to the crushing roller 5. The rotation of the fourth rotating shaft 9 drives the diameter adjusting disk 10 to rotate, and the diameter adjusting disk 10 drives the speed regulating disk 12 to rotate through the belt 11, and the speed regulating disk 12 drives the spline shaft 13 to rotate, and the spline shaft 13 drives the third rotating shaft 6 to rotate, and the third rotating shaft 6 drives the crushing roller 5 to rotate, and the crushing roller 5 crushes the branch, and the crushed residue falls from the arc-shaped crushing net 7 into the unloading device.

[0034] What is different is that when the pressure roller 3 is lifted, the lifting range of the pressure roller 3 is different according to the diameter of the branch. The lifting of the pressure roller 3 drives the fourth rotating shaft 9 to lift, and the fourth rotating shaft 9 drives the slider 20 and the diameter adjusting disk 10 to lift, and the slider 20 slides upward along the arc-shaped slide groove 19. The diameter adjusting disk 10 tightens the belt 11 so that the belt 11 squeezes the speed regulating disk 12, and the speed regulating disks 12 move away from each other along the spline shaft 13, so that the radial distance between the axis of the speed regulating disk 12 and the belt 11 is reduced, thereby achieving the effect of increasing the transmission ratio, so that the crushing roller 5 can obtain different rotation speeds, and the thicker the branch, the closer the axis of the speed regulating disk 12 and the belt 11 The smaller the radial distance, the faster the crushing roller 5 rotates, which prevents the problem of jamming and blockage caused by the crushing roller 5 crushing the branches too thick and the speed at which the crushing roller 5 crushes the branches cannot keep up with the speed of the forced feeding of the pressure roller 3, thereby improving the crushing efficiency. After the branches are crushed, the pressure roller 3 is reset under the action of gravity, and the pressure roller 3 drives the fourth rotating shaft 9 to reset. The fourth rotating shaft 9 drives the slider 20 and the diameter adjusting disk 10 to move downward and reset. The slider 20 slides downward along the arc-shaped slide groove 19, the belt 11 loses its tension, and the speed regulating disk 12 is reset under the action of the reset component 14. The radial distance between the axis of the speed regulating disk 12 and the belt 11 increases until it is restored.

[0035] It should be noted that the driving device 21 is a motor.

[0036] In one case of this embodiment, a roller 15 is installed at the bottom of the branch chipper housing 1.

[0037] like Figure 3 As shown, the bearing assembly 2 is a first conveyor belt, and the first conveyor belt is connected to a transmission device 4, and the transmission device 4 includes: The first rotating shaft 41 is rotatably connected to both sides of the shredder housing 1; The swing plate 42 is rotatably connected to the first rotating shaft 41 and is rotatably connected to the fourth rotating shaft 9. The driving device 21 is installed on one side of the swing plate 42; A second pulley assembly 43, wherein the two pulleys are mounted on the first rotating shaft 41 and the fourth rotating shaft 9 respectively; The third pulley assembly 44 has two pulleys respectively mounted on the first rotating shaft 41 and a rotating roller of the first conveyor belt.

[0038] In the embodiment of the present invention, the driving device 21 drives the fourth rotating shaft 9 to rotate, and the fourth rotating shaft 9 drives the pressure roller 3 to rotate. At the same time, the fourth rotating shaft 9 drives the first rotating shaft 41 to rotate through the second pulley assembly 43, and the first rotating shaft 41 drives the supporting assembly 2 to operate through the third pulley assembly 44, thereby ensuring that the rotation speed of the pressure roller 3 is the same as the rotation speed of the first conveyor belt roller.

[0039] like Figure 2 As shown, as another preferred embodiment of the present invention, the unloading device comprises: The second conveyor belt 16 is installed below the arc-shaped crushing net 7; The guide plate 18 is arranged at the discharge end of the second conveyor belt 16 and is symmetrically distributed. The guide plate 18 is fixedly connected to the inner wall of the shredder housing 1, and the bottom thereof abuts against the second conveyor belt 16; A first pulley assembly 17, wherein two pulleys are respectively mounted on the third rotating shaft 6 and a rotating roller of the second conveyor belt 16; The screening mechanism 8 is arranged below the discharge end of the second conveyor belt 16 and is used for screening the crushed branch debris and leaf debris.

[0040] In the embodiment of the present invention, the crushed slag falls from the arc-shaped crushing net 7 onto the second conveyor belt 16, and the second conveyor belt 16 transports the crushed slag to the discharge end. The crushed slag is gathered under the guiding action of the guide plate 18 and falls into the screening mechanism 8 for screening.

The second spring 142 is fixedly connected to the connecting block 141 .

[0042] In the embodiment of the present invention, when the diameter adjusting disk 10 moves downward to reset, the belt 11 loses its tension, and the speed adjusting disk 12 moves toward each other and resets under the elastic action of the second spring 142. The speed adjusting disk 12 squeezes the belt 11, so that the radial distance between the axis of the speed adjusting disk 12 and the belt 11 increases until it is restored.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the diameter adjustment disk 10 includes: A visual detection sensor 101 is fixedly connected to the feed end of the shredder housing 1; The disc 102 is fixedly connected to one end of the fourth rotating shaft 9; The chutes 103 are arranged on the disc 102 at equal intervals around the circumference; A slide bar 104 is slidably connected in the slide slot 103; The arc-shaped support block 105 is fixedly connected to the outer side of the slide bar 104; The arc groove 106 is formed on the arc support block 105, and the inner wall of the arc groove 106 abuts against the bottom of the isosceles trapezoidal cross section of the belt 11; A rotating disk 107 is coaxially rotatably connected to the circular disk 102; Guide grooves 108 are provided on the rotating disk 107 at equal intervals around the circumference; The guide rod 109 is fixedly connected to the slide rod 104 and slides in cooperation with the guide groove 108; A fixing seat 110, fixedly connected to the disc 102; The motor 111 is fixedly connected to the fixing base 110 , and an output end thereof is fixedly connected to the rotating disk 107 .

[0044] In the embodiment of the present invention, when the fourth rotating shaft 9 rotates, the fourth rotating shaft 9 drives the disc 102 to rotate, the disc 102 drives the slide rod 104 and the arc-shaped support block 105 to rotate, the arc-shaped support block 105 drives the belt 11 to rotate under the action of friction force, and the belt 11 drives the speed regulating disk 12 to rotate.

[0045] When the fourth rotating shaft 9 is lifted, the fourth rotating shaft 9 drives the disc 102, the slide bar 104 and the arc support block 105 to be lifted. The arc support block 105 is lifted to tighten the belt 11 so that the belt 11 squeezes the speed regulating disk 12, so that the speed regulating disks 12 move away from each other along the spline shaft 13.

[0046] When the visual detection sensor 101 detects that the number of branches transmitted by the bearing assembly 2 is too large, a start signal is transmitted to the motor 111, and the motor 111 drives the rotating disk 107 to rotate, and the rotating disk 107 drives the guide groove 108 to rotate, and the guide rod 109 slides outward along the guide groove 108, and the guide rod 109 drives the slide bar 104 to move outward under the limiting action of the slide groove 103, and the slide bar 104 drives the arc support block 105 to move outward, and the arc support block 105 drives the belt 11 to open, so that the radial distance of the belt 11 and the axial distance of the disk 102 are increased, and the belt 11 opens and squeezes the speed regulating disk 12, so that The speed regulating disks 12 move away from each other along the spline shaft 13, so that the radial distance between the axis of the speed regulating disk 12 and the belt 11 is reduced, thereby adjusting the transmission ratio of the diameter regulating disk 10 and the speed regulating disk 12, thereby slowing down the rotation speed of the pressure roller 3 and speeding up the rotation speed of the crushing roller 5. When the thickness of the branches is the same, the transmission ratio of the diameter regulating disk 10 to the speed regulating disk 12 can be changed according to the number of branches, thereby slowing down the feeding speed of the pressure roller 3 and speeding up the crushing speed of the crushing roller 5, further avoiding the problem that the speed of crushing the branches by the crushing roller 5 cannot keep up with the speed of forced feeding by the pressure roller 3, thereby causing jamming and blockage problems.

[0047] It should be noted that a battery is installed inside the motor 111 to provide power for the motor 111 .

At the same time, the roller of the second conveyor belt 16 drives the round rod 86 to rotate through the fourth pulley assembly 85, and the round rod 86 drives the protrusion 87 to rotate. The protrusion 87 intermittently contacts the screen 811 and drives the screen 811 to vibrate intermittently under the action of the first spring 812, thereby accelerating the screening of branch debris and leaf debris. The screened leaf debris is discharged from the leaf discharge hopper 84, and the screened branch debris remains on the screen 811.

The first arc-shaped baffle plate 831 is used to shield the branch discharge hopper 83 during screening; The second arc-shaped baffle plate 832 is fixedly connected to the first connecting plate 830 and is slidably connected to the inner wall of the screening cylinder 81. The first arc-shaped baffle plate 831 is used to shield the material discharge hopper 82 when discharging materials; There are two limit bars 835 , both of which are fixedly connected to the inner wall of the screening cylinder 81 . The two limit bars 835 are respectively arranged on a side of the lower hopper 82 away from the second arc-shaped baffle 832 and a side of the leaf discharge hopper 84 away from the first arc-shaped baffle 831 .

[0051] In the embodiment of the present invention, when a certain amount of branch debris accumulates on the screen 811, the second motor 815 drives the first connecting rod 816 to rotate, and the first connecting rod 816 drives the fan-shaped plate 819 to swing through the second connecting rod 817, and the fan-shaped plate 819 drives the second rotating shaft 818 to rotate back and forth; when the fan-shaped plate 819 moves toward the side close to the second motor 815, the fan-shaped plate 819 drives the second rotating shaft 818 to rotate, and the second rotating shaft 818 drives the second gear 824 to rotate, and the second gear 824 drives the third gear 826 to rotate, and the third gear 826 drives the second round tube 825 to rotate, and at the same time, the third gear 826 drives the fixed plate 828 to rotate through the torsion spring 829, and the fixed plate 828 drives The third circular tube 827 rotates, and the third circular tube 827 drives the first connecting plate 830 and the second connecting plate 834 to move. The movement of the first connecting plate 830 and the second connecting plate 834 drives the rotating ring 833 to rotate. At the same time, the first connecting plate 830 and the second connecting plate 834 drive the second arc baffle plate 832 and the first arc baffle plate 831 to move with the round rod 86 as the axis until the second arc baffle plate 832 and the first arc baffle plate 831 are against the limit bar 835, and then the fan plate 819 continues to move toward the side close to the second motor 815. Under the obstruction of the limit bar 835, the rotation of the third gear 826 will not drive the fixed plate 828 to rotate through the torsion spring 829, but will only twist the torsion spring 829.

[0052] When the fan plate 819 moves toward the side close to the second motor 815, the fan plate 819 drives the limit block 821 to move, and the limit block 821 away from the second motor 815 moves to abut against the arc rack 822, and then the fan plate 819 moves to drive the limit block 821 and the arc rack 822 to move together, and the arc rack 822 moves along the arc slide rail 820, and the arc rack 822 drives the first gear 823 to rotate, and the first gear 823 drives the first round tube 88 to rotate, and the first round tube 88 drives the fixed frame 810 and the screen 811 to rotate. During the rotation process, the screen 811 keeps vibrating and screening intermittently. When the screen 811 rotates to a horizontal state, the first arc baffle 831 and the second arc baffle 832 just move against the limit bar 835. At this time, the second arc baffle 832 covers the lower hopper 82, and the first arc baffle 831 is separated from the branch discharge hopper 83. The debris conveyed by the second conveyor belt 16 will accumulate in the lower hopper 82 and be blocked by the second arc baffle 832. Then the screen 811 continues to rotate to the unloading state, that is, the side of the fixed frame 810 that abuts against the inner wall of the screening cylinder 81 is at the lowest point. At this time, the branch debris on the screen 811 slides from the screen 811 into the branch discharge hopper 83 and is discharged from the screening cylinder 81.

[0053] When the fan plate 819 moves away from the second motor 815, the fan plate 819 drives the limit block 821 to move until the limit block 821 close to the second motor 815 hits the arc rack 822. Before this, the screen 811 has been in a feeding state, and the screen 811 has been vibrating intermittently, further accelerating the feeding speed. Then the fan plate 819 continues to move away from the second motor 815, and the fan plate 819 drives the limit block 821 and the arc rack 822 to move together. The arc rack 822 moves along the arc slide rail 820, and the arc rack 822 drives the first gear 823 to rotate in the opposite direction. The first gear 823 drives the first circular tube 88 to rotate in the opposite direction, and the first circular tube 88 drives the fixed frame 810 and the screen 811 to rotate in the opposite direction until the screen 811 rotates to a horizontal state. At the same time, the fan plate 819 moves to drive the second rotating shaft 818 to rotate in the opposite direction, and the second rotating shaft 818 drives the second gear 824 to rotate in the opposite direction. The second gear 824 drives the third gear 826 to rotate in the opposite direction, and the third gear 826 drives the torsion spring 829 to twist in the opposite direction and reset. That is, before the screen 811 rotates to a horizontal state, the second arc baffle 832 still covers the lower hopper 82, and the first arc baffle 831 still detaches from the branch discharge hopper 83.

[0054] The screen 811 continues to rotate from a horizontal state to a loading state (the side of the fixed frame 810 abutting against the inner wall of the screening cylinder 81 is at the highest point). At this time, the third gear 826 rotates in the opposite direction and drives the fixed plate 828 to rotate in the opposite direction through the torsion spring 829. The fixed plate 828 drives the third circular tube 827 to rotate in the opposite direction. The third circular tube 827 drives the first connecting plate 830 and the second connecting plate 834 to move in the opposite direction. The first connecting plate 830 and the second connecting plate 834 drive the second arc-shaped baffle plate 832 and the first arc-shaped baffle plate 831 to move in the opposite direction about the axis of the round rod 86, so that the second arc-shaped baffle plate 832 is separated from the lower hopper 82, and the first arc-shaped baffle plate 831 covers the branch discharge hopper 83 again. At this time, the debris accumulated in the lower hopper 82 falls into the screening cylinder 81 for screening, and the first arc-shaped baffle plate 831 covers the branch discharge hopper 83, and the screened leaf debris will not be discharged from the branch discharge hopper 83.

[0055] The above embodiment of the present invention provides an ultra-fine grinding electric branch shredder, which achieves the following technical effects: In the embodiment of the present invention, the driving device 21 drives the fourth rotating shaft 9 to rotate, and the fourth rotating shaft 9 drives the pressure roller 3 to rotate. At the same time, the fourth rotating shaft 9 drives the first rotating shaft 41 to rotate through the second pulley assembly 43, and the first rotating shaft 41 drives the bearing assembly 2 to operate through the third pulley assembly 44, ensuring that the rotation speed of the pressure roller 3 is the same as the rotation speed of the first conveyor belt roller. The branches are placed on the bearing assembly 2, and the bearing assembly 2 drives the branches to move under the pressure roller 3. The protrusions on the pressure roller 3 are stuck on the branches, causing the pressure roller 3 to lift, and the pressure roller 3 rotates to transport the branches to the crushing roller 5. The rotation of the fourth rotating shaft 9 also drives the disc 102 to rotate, and the disc 102 drives the slide rod 104 and The arc-shaped support block 105 rotates, and the arc-shaped support block 105 drives the belt 11 to rotate under the action of friction force, and the belt 11 drives the speed regulating disk 12 to rotate, and the arc-shaped support block 105 drives the speed regulating disk 12 to rotate through the belt 11, and the speed regulating disk 12 drives the spline shaft 13 to rotate, and the spline shaft 13 drives the third rotating shaft 6 to rotate, and the third rotating shaft 6 drives the crushing roller 5 to rotate, and the crushing roller 5 crushes the branches, and the crushed debris falls from the arc-shaped crushing net 7 onto the second conveyor belt 16, and the second conveyor belt 16 transports the debris to the discharge end, and the debris is gathered under the guiding action of the guide plate 18 and falls into the screening drum 81 from the lower hopper 82, and then falls on the screen 811 for screening.

[0056] When the pressure roller 3 is lifted, the lifting range of the pressure roller 3 is different according to the different diameters of the branches. The lifting of the pressure roller 3 drives the fourth rotating shaft 9 to lift, and the fourth rotating shaft 9 drives the slider 20, the disc 102, the slide bar 104 and the arc-shaped support block 105 to lift. The slider 20 slides upward along the arc-shaped slide groove 19, and the arc-shaped support block 105 lifts and tightens the belt 11 so that the belt 11 squeezes the speed regulating disk 12, and the speed regulating disks 12 move away from each other along the spline shaft 13, so that the radial distance between the axis of the speed regulating disk 12 and the belt 11 is reduced, thereby achieving the effect of increasing the transmission ratio, so that the crushing roller 5 can obtain different rotation speeds, and the thicker the branch, the smaller the radial distance between the axis of the speed regulating disk 12 and the belt 11, and the crushing roller 5 The faster the rotation speed is, the problem of jamming and blockage can be prevented because the speed of crushing roller 5 cannot keep up with the speed of forced feeding of pressure roller 3 due to branches being too thick, thereby improving the crushing efficiency. After the branches are crushed, pressure roller 3 is reset under the action of gravity, and pressure roller 3 drives the fourth rotating shaft 9 to reset. The fourth rotating shaft 9 drives the slider 20, the disc 102, the slide bar 104 and the arc-shaped support block 105 to move downward and reset. The slider 20 slides downward along the arc-shaped slide groove 19, the belt 11 loses its tension, and the speed regulating disk 12 moves toward each other and resets under the elastic action of the second spring 142. The speed regulating disk 12 squeezes the belt 11, so that the radial distance between the axis of the speed regulating disk 12 and the belt 11 increases until it is restored.

[0057] When the visual detection sensor 101 detects that the number of branches transmitted by the bearing assembly 2 is too large, a start signal is transmitted to the motor 111, and the motor 111 drives the rotating disk 107 to rotate, and the rotating disk 107 drives the guide groove 108 to rotate, and the guide rod 109 slides outward along the guide groove 108, and the guide rod 109 drives the slide bar 104 to move outward under the limiting action of the slide groove 103, and the slide bar 104 drives the arc support block 105 to move outward, and the arc support block 105 drives the belt 11 to open, so that the radial distance of the belt 11 and the axial distance of the disk 102 are increased, and the belt 11 opens and squeezes the speed regulating disk 12, so that The speed regulating disks 12 move away from each other along the spline shaft 13, so that the radial distance between the axis of the speed regulating disk 12 and the belt 11 is reduced, thereby adjusting the transmission ratio of the diameter regulating disk 10 and the speed regulating disk 12, thereby slowing down the rotation speed of the pressure roller 3 and speeding up the rotation speed of the crushing roller 5. When the thickness of the branches is the same, the transmission ratio of the diameter regulating disk 10 to the speed regulating disk 12 can be changed according to the number of branches, thereby slowing down the feeding speed of the pressure roller 3 and speeding up the crushing speed of the crushing roller 5, further avoiding the problem that the speed of crushing the branches by the crushing roller 5 cannot keep up with the speed of forced feeding by the pressure roller 3, thereby causing jamming and blockage problems.

[0058] The debris falling on the screen 811 first screens out a part of the leaf debris. At the same time, the roller of the second conveyor belt 16 drives the round rod 86 to rotate through the fourth pulley assembly 85, and the round rod 86 drives the protrusion 87 to rotate. The protrusion 87 intermittently contacts the screen 811 and drives the screen 811 to vibrate intermittently under the action of the first spring 812, thereby accelerating the screening of branch debris and leaf debris. The screened leaf debris is discharged from the leaf discharge hopper 84, and the screened branch debris remains on the screen 811.

[0059] When a certain amount of branch debris accumulates on the screen 811, the second motor 815 drives the first connecting rod 816 to rotate, and the first connecting rod 816 drives the fan-shaped plate 819 to swing through the second connecting rod 817, and the fan-shaped plate 819 drives the second rotating shaft 818 to rotate back and forth; when the fan-shaped plate 819 moves toward the side close to the second motor 815, the fan-shaped plate 819 drives the second rotating shaft 818 to rotate, and the second rotating shaft 818 drives the second gear 824 to rotate, and the second gear 824 drives the third gear 826 to rotate, and the third gear 826 drives the second round tube 825 to rotate. At the same time, the third gear 826 drives the fixed plate 828 to rotate through the torsion spring 829, and the fixed plate 828 drives the third round tube 825 to rotate. 827 rotates, the third round tube 827 drives the first connecting plate 830 and the second connecting plate 834 to move, and the movement of the first connecting plate 830 and the second connecting plate 834 drives the rotating ring 833 to rotate. At the same time, the first connecting plate 830 and the second connecting plate 834 drive the second arc baffle plate 832 and the first arc baffle plate 831 to move with the round rod 86 as the axis until the second arc baffle plate 832 and the first arc baffle plate 831 are against the limit bar 835, and then the fan plate 819 continues to move toward the side close to the second motor 815. Under the obstruction of the limit bar 835, the rotation of the third gear 826 will not drive the fixed plate 828 to rotate through the torsion spring 829, but will only twist the torsion spring 829.

[0060] When the fan plate 819 moves toward the side close to the second motor 815, the fan plate 819 drives the limit block 821 to move, and the limit block 821 away from the second motor 815 moves to abut against the arc rack 822, and then the fan plate 819 moves to drive the limit block 821 and the arc rack 822 to move together, and the arc rack 822 moves along the arc slide rail 820, and the arc rack 822 drives the first gear 823 to rotate, and the first gear 823 drives the first round tube 88 to rotate, and the first round tube 88 drives the fixed frame 810 and the screen 811 to rotate. During the rotation process, the screen 811 keeps vibrating and screening intermittently. When the screen 811 rotates to a horizontal state, the first arc baffle 831 and the second arc baffle 832 just move against the limit bar 835. At this time, the second arc baffle 832 covers the lower hopper 82, and the first arc baffle 831 is separated from the branch discharge hopper 83. The debris conveyed by the second conveyor belt 16 will accumulate in the lower hopper 82 and be blocked by the second arc baffle 832. Then the screen 811 continues to rotate to the unloading state, that is, the side of the fixed frame 810 that abuts against the inner wall of the screening cylinder 81 is at the lowest point. At this time, the branch debris on the screen 811 slides from the screen 811 into the branch discharge hopper 83 and is discharged from the screening cylinder 81.

[0061] When the fan plate 819 moves away from the second motor 815, the fan plate 819 drives the limit block 821 to move until the limit block 821 close to the second motor 815 hits the arc rack 822. Before this, the screen 811 has been in a feeding state, and the screen 811 has been vibrating intermittently, further accelerating the feeding speed. Then the fan plate 819 continues to move away from the second motor 815, and the fan plate 819 drives the limit block 821 and the arc rack 822 to move together. The arc rack 822 moves along the arc slide rail 820, and the arc rack 822 drives the first gear 823 to rotate in the opposite direction. The first gear 823 drives the first circular tube 88 to rotate in the opposite direction, and the first circular tube 88 drives the fixed frame 810 and the screen 811 to rotate in the opposite direction until the screen 811 rotates to a horizontal state. At the same time, the fan plate 819 moves to drive the second rotating shaft 818 to rotate in the opposite direction, and the second rotating shaft 818 drives the second gear 824 to rotate in the opposite direction. The second gear 824 drives the third gear 826 to rotate in the opposite direction, and the third gear 826 drives the torsion spring 829 to twist in the opposite direction and reset. That is, before the screen 811 rotates to a horizontal state, the second arc baffle 832 still covers the lower hopper 82, and the first arc baffle 831 still detaches from the branch discharge hopper 83.

[0062] The screen 811 continues to rotate from a horizontal state to a loading state (the side of the fixed frame 810 abutting against the inner wall of the screening cylinder 81 is at the highest point). At this time, the third gear 826 rotates in the opposite direction and drives the fixed plate 828 to rotate in the opposite direction through the torsion spring 829. The fixed plate 828 drives the third circular tube 827 to rotate in the opposite direction. The third circular tube 827 drives the first connecting plate 830 and the second connecting plate 834 to move in the opposite direction. The first connecting plate 830 and the second connecting plate 834 drive the second arc-shaped baffle plate 832 and the first arc-shaped baffle plate 831 to move in the opposite direction about the axis of the round rod 86, so that the second arc-shaped baffle plate 832 is separated from the lower hopper 82, and the first arc-shaped baffle plate 831 covers the branch discharge hopper 83 again. At this time, the debris accumulated in the lower hopper 82 falls into the screening cylinder 81 for screening, and the first arc-shaped baffle plate 831 covers the branch discharge hopper 83, and the screened leaf debris will not be discharged from the branch discharge hopper 83.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
