Detailed Description

As shown in figures 1 and 2, the hand-held electric buffering weeding device comprises a handle 9, wherein the handle 9 is a basic component of the whole device, and other components are directly or indirectly arranged on the handle 9.

A sliding rod 3 is arranged on the front end face of the handle 9, a hoe rod 2 is arranged at the front end of the sliding rod 3, the middle of the hoe rod 2 is hinged with the front end of the sliding rod 3, and a hoe 1 is fixed at the bottom of the hoe rod 2.

The slide bar 3 is sleeved with a slide block 4, the left end of the slide block 4 is hinged with a pull rod 15, and the other end of the pull rod 15 is hinged with the top end of the hoe rod 2.

When the sliding block 4 moves back and forth along the sliding rod 3, the pull rod 15 is pulled to swing, the pull rod 15 further drives the hoe rod 2 to swing while swinging, and further drives the hoe 1 to move back and forth, and when the hoe 1 moves back and forth, the hoe 1 is placed at a weed position, and weeding and soil loosening can be carried out.

A block spring stop dog 6 is fixed on the slide rod 3 behind the slide block 4, a buffer spring 5 is sleeved on the slide rod 3, the front end of the buffer spring 5 is connected with the slide block 4, and the rear end of the buffer spring is fixedly connected with the spring stop dog 6.

When the sliding block 4 moves back and forth along the sliding rod 3, the sliding block 4 is connected with the buffer spring 5, so that the sliding block 4 can be stressed by the pressure or the pulling force of the buffer spring 5, and the stress of the sliding block 4 is more uniform, therefore, the buffer spring 5 exists, and the sliding block 4 has good buffer performance in the sliding process along the sliding rod 3.

A motor 7 is fixed on the sliding rod 3 at the rear end of the spring stop 6, a speed reducer 8 is arranged on the motor 7, a main shaft 12 is arranged on the speed reducer 8, a crank 13 is fixed on the main shaft 12, the top end of the crank 13 is hinged with a connecting rod 14, and the other end of the connecting rod 14 is hinged with the sliding block 4.

Therefore, after the motor 7 is started and the speed is reduced by the speed reducer 8, the main shaft 12 can rotate continuously, the main shaft 12 can drive the crank 13 to rotate while rotating, the crank 13 can further drive the connecting rod 14 to swing back and forth, and the connecting rod 14 can drive the sliding block 4 to move back and forth along the sliding rod 3 in the process of swinging back and forth.

The pulling rod 15 is driven to swing by the sliding block 4 through the back and forth movement of the sliding block 4, the hoe rod 2 is driven to swing through the swinging of the pulling rod 15, the hoe 2 further drives the hoe 1 to move back and forth when swinging, and finally the back and forth movement of the hoe 1 is utilized to realize weeding and soil loosening.

Compare with current weeding device, the electronic buffering weeding device of hand-held type of this embodiment, hoe 1 is carried out to hoe and loosen the soil by motor 7 drive, degree of automation is high, low in labor strength, and can improve the work efficiency of hoe and loosening the soil greatly, in addition, slider 4 is at the in-process of front and back removal, buffer spring 5 can cushion it, and then the swing to pull rod 15, the swing of hoe rod 2 and the back-and-forth movement of hoe 1 all can play the cushioning effect, thereby make hoe 1 at the in-process of hoe and loosening the soil, the atress is more balanced, avoid motor 7's main shaft 12 to receive great impact, effectual improvement motor 4's life.

The handle 9 is provided with a battery 10, and the battery 10 is used for starting the motor 7 and is a power source for the motor 7 to work.

Be equipped with shift knob 11 on the outer wall of handle 9, battery 10, shift knob 11 and motor 7 are established ties mutually, through the opening and close of shift knob 11, can control opening and close of motor 7, and it is very convenient to control.

The electronic buffering device of weeding of hand-held type of this embodiment, hoe 1 perpendicular to hoe pole 2, hoe are semi-circular, are equipped with the cutting edge on hoe 1, and the cutting edge is the arc of indent, so, can further improve hoe's efficiency of weeding and the efficiency of loosening the soil, reduce hoe 1 at the resistance of weeding with the in-process of loosening the soil.

The electronic buffering of hand-held type of this embodiment device of weeding, battery 10 are the lithium cell, the lithium cell is installed in handle 9 with the detachable mode, and after the electric quantity of lithium cell finishes, can also charge it, makes it be full of the electric quantity once more.

The electronic buffering of hand-held type of this embodiment device of weeding is equipped with the decorative pattern on the surface of handle 9, is convenient for hold the handle tightly, and 9 avoid skidding because of the frictional force is not enough.
