Description

Technical Field

[0001] This utility model relates to the field of weeding and obstacle avoidance technology, and in particular to an orchard weeding and obstacle avoidance mechanism. Background Technology

[0002] A lawnmower, also known as a lawn mower, lawn trimmer, or lawn trimmer, is a mechanical tool that uses an engine to drive blades to rotate at high speed to cut vegetation. Weeds growing in orchards can have a significant impact on fruit tree yields, so lawnmowers are needed to clear weeds when there are many weeds in the orchard.

[0003] However, in existing technology, weeds easily grow in the soil near the roots of fruit trees in existing orchards, and most weeding machines generally lack obstacle avoidance mechanisms. Therefore, when weeding near the roots of fruit trees, the weeding machine is prone to accidentally cutting and injuring the fruit trees. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: weeds easily grow in the soil near the roots of fruit trees in orchards, and most weeding machines generally lack obstacle avoidance mechanisms. Therefore, when weeding near the roots of fruit trees, the weeding machine is prone to accidentally cutting and injuring the fruit trees.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an orchard weeding and obstacle avoidance mechanism, comprising a connecting push rod, a motor rotatably connected to the front end of the connecting push rod, and a weeding blade fixedly connected to the output shaft of the motor, a connecting frame fixedly connected to the upper end of the motor, an electric telescopic rod passing through the connecting frame, and a gripping rubber ring fixedly connected to one end of the electric telescopic rod, a rotating column rotatably connected to the surface of the gripping rubber ring, and a mobile power supply fixedly connected to one end of the connecting push rod.

[0006] In a preferred embodiment, a support frame is fixedly connected to the surface of the electric telescopic rod, and one end of the support frame is fixedly connected to the surface of the motor.

[0007] In a preferred embodiment, a mounting bracket is fixedly connected to the rear end of the connecting push rod, and a gripping rod is fixedly connected to the surface of the mounting bracket.

[0008] In a preferred embodiment, a sponge sleeve is fitted onto the outer surface of the grip rod.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention, when it is necessary to remove weeds from the root system of fruit trees, moves the weeding blade disc near the trunk of the fruit tree and keeps it closed to avoid accidentally damaging the fruit tree. Then, by extending the electric telescopic rod, the gripping rubber ring moves towards the trunk of the fruit tree, clamping the gripping rubber ring at the trunk. Using the gripping rubber ring as a fulcrum, the connecting push rod drives the motor and the weeding blade disc to move around the fruit tree. With the help of the electric telescopic rod and the gripping rubber ring, the weeding blade disc is prevented from moving further towards the fruit tree when it moves around the fruit tree, effectively preventing the rotating weeding blade disc from accidentally damaging the fruit tree and achieving a good obstacle avoidance effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: an orchard weeding and obstacle avoidance mechanism, including a connecting push rod 1. A motor 2 is rotatably connected to the front end of the connecting push rod 1, and a weeding blade 3 is fixedly connected to the output shaft of the motor 2. By starting the motor 2, the weeding blade 3 is driven to rotate. Then, by grasping the surface of the connecting push rod 1 and pushing, the motor 2 and the weeding blade 3 move, allowing the rotating weeding blade 3 to cut weeds along the way. A connecting frame 4 is fixedly connected to the upper end of the motor 2. The connecting frame 4 provides an installation point for an electric telescopic rod 5 on the top of the motor 2. The electric telescopic rod 5 is fixedly fixed through the connecting frame 4. The telescopic rod 5 controls the left and right movement of the gripping rubber ring 7 by its extension and retraction. A gripping rubber ring 7 is fixedly connected to one end of the electric telescopic rod 5, and a rotating column 8 is rotatably connected to the surface of the gripping rubber ring 7. A mobile power supply 12 is fixedly connected to one end of the connecting push rod 1. The mobile power supply 12 is electrically connected to the motor 2 and the electric telescopic rod 5, facilitating the control of the electric... The motor 2 and the electric telescopic pole 5 provide outdoor power. When it is necessary to remove weeds around the roots of the fruit trees, the weeding blade 3 is moved to the vicinity of the tree trunk and kept closed to avoid accidentally damaging the fruit trees. Then, by extending the electric telescopic pole 5, the gripping rubber ring 7 is moved towards the tree trunk, clamping the gripping rubber ring 7 at the trunk. Using the gripping rubber ring 7 as a fulcrum, the connecting push rod 1 is pushed, which in turn drives the motor 2 and the weeding blade 3 to move around the fruit tree. During this process, the gripping rubber ring 7 will also move around the connecting push rod 1, the motor 2, and the... When the weeding blade 3 moves around the fruit tree, it rotates on the trunk. When the gripping rubber ring 7 rotates, the rotating column 8 also rotates and rolls on the trunk, reducing the resistance of the gripping rubber ring 7 rotating on the trunk. This makes it easier to move the push connecting rod 1. With the help of the electric telescopic rod 5 and the gripping rubber ring 7, the weeding blade 3 is prevented from moving further toward the fruit tree when it moves around the fruit tree, effectively preventing the rotating weeding blade 3 from accidentally injuring the fruit tree and achieving a good obstacle avoidance effect.

[0019] Example 2

[0020] like Figure 1-3 As shown, a support frame 6 is fixedly connected to the surface of the electric telescopic rod 5, and one end of the support frame 6 is fixedly connected to the surface of the motor 2. The support frame 6 provides support for the electric telescopic rod 5 and improves the stability of the electric telescopic rod 5 connected to the connecting frame 4. A mounting frame 9 is fixedly connected to the rear end of the connecting push rod 1, and a gripping rod 10 is fixedly connected to the surface of the mounting frame 9. With the mounting frame 9 and the gripping rod 10, the user can grip the horizontally arranged gripping rod 10 to push it, which is more convenient than holding the surface of the connecting push rod 1 to push and drive the motor 2 and the weeding blade 3. A sponge sleeve 11 is covered on the outer surface of the gripping rod 10. The sponge sleeve 11 improves the comfort of the hand gripping the gripping rod 10 and can absorb the sweat on the palm to avoid the sticky feeling of the palm after a long time of gripping.
