A storage battery is arranged in the inner cavity of the fixed frame. The left side of the fixed frame is fixedly connected with a controller. The center of the top of the left fixed box is fixedly connected with a servo motor. By using a combing rod, a protective shell, a trimming blade, a rotating rod, a driving motor, a right collection box, an induced draft fan, a through pipe, a telescopic hose, a lead screw, a servo motor, a ranging sensor, a screw sleeve, a one-way exhaust valve and a screen in cooperation, the utility model has the advantages of height adjustment and collection and treatment, and solves the problems that the existing trimming device cannot flexibly adjust the trimming height according to actual needs, cannot perform collection and treatment, increases the labor intensity of subsequent cleaning, and reduces the practicability of the trimming device. However, the patent still has the following deficiencies. When the screen on the device is used for a long time, it is inconvenient to prevent blockage of the device. The screen may be blocked after long-term use, resulting in a possible reduction in the working efficiency of the screen on the device. Therefore, it is necessary to improve the existing technology. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a weed trimmer for fruit tree planting is proposed, which solves the problem that when the screen on the device is used for a long time, the device has no anti-blocking mechanism, and the screen may be blocked after long-term use, resulting in a possible reduction in the working efficiency of the screen on the device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A weed trimmer for fruit tree planting, comprising a main body of the trimming device. A screen is arranged inside the main body of the trimming device. A motor is fixedly installed on the outer side of the main body of the trimming device. The rotating shaft of the motor is rotationally connected to the main body of the trimming device. The left end of the rotating shaft of the motor is fixedly connected to a screw rod. The screw rod is rotationally connected inside the main body of the trimming device. A fixed block is fixedly connected inside the main body of the trimming device. The screw rod is rotationally connected inside the fixed block. A threaded block is threadedly connected to the outer side of the screw rod. A guiding block is fixedly connected to the lower end of the threaded block. A guiding rod is slidably connected inside the guiding block. A groove is formed inside the guiding block. An annular sleeve is slidably connected to the outer side of the guiding rod. A sealing sleeve is fixedly connected to the annular sleeve. A bolt is threadedly connected inside the guiding block. An impact block is fixedly connected to the upper end of the threaded block. An elastic block is fixedly connected to the lower end of the screen. By rotating the screw rod, a threaded movement occurs between the screw rod and the threaded block. The movement of the threaded block drives the movement of components such as the impact block. The movement of the impact block impacts the elastic block to vibrate. The vibration of the elastic block drives the vibration of the screen, thereby preventing the screen from being blocked and preventing the working efficiency of the screen on the device from being reduced.

[0006] In addition, a preferred structure is that a bearing is fixedly sleeved inside the fixed block, and the screw rod is fixedly sleeved inside the bearing. By designing the bearing, it can be used to support the rotation of the screw rod.

[0007] In addition, a preferred structure is that one end of the guiding rod is fixedly connected to a fixed block, and the other end of the guiding rod is fixedly connected to the main body of the trimming device. By designing the guiding rod, it can guide the guiding block.

[0008] In addition, a preferred structure is that balls are arranged inside the groove, and the outer sides of the balls are in contact with the guiding rod. By designing the balls, the friction between the guiding block and the guiding rod can be reduced.

[0009] In addition, a preferred structure is that the guiding block is in contact with the sealing sleeve, and the guiding rod is slidably connected inside the sealing sleeve. By designing the sealing sleeve, the inside of the guiding block can be sealed.

[0010] In addition, a preferred structure is that the bolt is movably connected inside the sealing sleeve, and the outer side of the bolt is in contact with the annular sleeve. By designing the bolt, the annular sleeve and the sealing sleeve can be fixed.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By designing components such as the motor, screw rod, fixed block, bearing, threaded block, and guiding block, the present utility model makes the screw rod rotate to cause a threaded movement with the threaded block. The movement of the threaded block drives the movement of components such as the impact block. The movement of the impact block impacts the elastic block to vibrate. The vibration of the elastic block drives the vibration of the screen, thereby preventing the screen from being blocked and preventing the working efficiency of the screen on the device from being reduced.

The left end of the rotating shaft of the motor 3 is fixedly connected to a screw 4. The screw 4 is rotatably connected inside the pruning device body 1. A fixed block 5 is fixedly connected inside the pruning device body 1. A bearing 6 is fixedly sleeved inside the fixed block 5. The screw 4 is fixedly sleeved inside the bearing 6. By designing the bearing 6, it can be used to support the rotation of the screw 4.

[0020] Refer to Figures 1 - 4, a screw rod 4 is rotatably connected inside a fixing block 5. A threaded block 7 is connected to the outside of the screw rod 4 by threads. A guiding block 8 is fixedly connected to the lower end of the threaded block 7. A guiding rod 9 is slidably connected inside the guiding block 8. One end of the guiding rod 9 is fixedly connected to the fixing block 5, and the other end of the guiding rod 9 is fixedly connected to a trimming device body 1. By designing the guiding rod 9, the guiding block 8 can be guided. A groove 10 is formed inside the guiding block 8, and a ball 11 is arranged inside the groove 10. The outside of the ball 11 contacts the guiding rod 9. By designing the ball 11, the friction between the guiding block 8 and the guiding rod 9 can be reduced. A sealing sleeve 12 contacts the inside of the guiding block 8, and the guiding rod 9 is slidably connected inside the sealing sleeve 12. By designing the sealing sleeve 12, the inside of the guiding block 8 can be sealed.

[0021] Refer to Figures 2 - 4 , a ring sleeve 13 is slidably connected to the outside of the guiding rod 9. The sealing sleeve 12 is fixedly connected to the ring sleeve 13.

The movement of the impact block 15 impacts the elastic block 16 to vibrate, and the vibration of the elastic block 16 drives the screen 2 to vibrate, thereby preventing the screen 2 from being blocked and preventing the working efficiency of the screen 2 on the device from decreasing.

[0022] The specific implementation process of the present utility model is as follows: The basic principle of the weed trimmer has been disclosed in the utility model patent with the patent authorization announcement number CN214282191U;

[0023] When the screen 2 on the device is used for a long time, the motor 3 is started. The motor 3 drives the screw rod 4 to rotate. The rotation of the screw rod 4 causes a threaded movement with the threaded block 7, thereby causing the threaded block 7 to generate a relative displacement. The movement of the threaded block 7 drives the guiding block 8 and the impact block 15 to move. The movement of the guiding block 8 drives the groove 10, the sealing sleeve 12, the ring sleeve 13, and the bolt 14 to move. The movement of the groove 10 drives the ball 11 to move. The movement of the impact block 15 impacts the elastic block 16, thereby causing the elastic block 16 to vibrate. The vibration of the elastic block 16 drives the screen 2 to vibrate, thereby preventing the screen 2 from being blocked during long-term use and preventing the working efficiency of the screen 2 on the device from decreasing.
