[0014] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0016] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0017] Combine Figure 1-3As shown, the orchard weeder includes a cart 1, which is provided with a fixed frame 2, and three connecting shafts 3 and a pair of screw rods 4 are rotatably provided on the fixed frame 2. The screw rods 4 are covered with screw rod sleeves 5, and the screw rod sleeves 5 are jointly provided with an adjustment plate 6. The adjustment plate 6 is provided with a weeding head 7 corresponding to each connecting shaft 3, and a square column 8 is provided above the weeding head 7. The bottom of the connecting shaft 3 is provided with a square groove facing upward (blocked in the figure), and the square column 8 is located in the corresponding square groove. A driven gear 9 is also provided on the screw rod 4, and an adjustment motor 10 is provided on the fixed frame 2. A driving gear 11 is provided on the drive shaft of the adjustment motor 10, and a chain 12 is provided between the driving gear 11 and the driven gear 9. The cart 1 is also provided with a driving mechanism for driving the connecting shaft 3 to rotate.

[0018] In the daily management of an orchard, weeding is an important operation. Proper weeding can not only promote the growth of fruit trees in the orchard, but also beautify the orchard.

[0019] In this structure, the cart 1 is provided with a pair of rotatable wheels 13. To use this weeder to weed an orchard, a worker first holds the handle and rotates it as needed, aligning all the weeding heads toward the roots of the weeds. The worker then pushes the weeder to begin weeding. Simultaneously, the drive mechanism drives all the connecting shafts to rotate synchronously, causing the weeding heads to rotate accordingly. This rapid rotation of the weeding heads achieves the desired weeding effect.

[0020] In this structure, the weeding head can be adjusted to the required weeding height. When the height of the weeding head is adjusted, the adjustment motor first drives the driving gear to rotate. Under the linkage of the chain, the two screws rotate synchronously. As the screw rotates, the screw sleeve drives the adjustment plate to move along the height direction of the screw, and the weeding head moves vertically. When the adjustment plate is adjusted into place, the drive motor stops working. During the vertical movement of the weeding head, the square column above the weeding head will move vertically within the corresponding square groove.

[0021] The structural design of the weeding knife not only allows the weeding knife head to be adjusted up and down, but also does not affect the rotation of the weeding knife head.

[0022] As a preferred structure, Figure 1 The cart 1 is further provided with a retaining frame 14 , and a plurality of tooth grooves 15 are formed at the front end of the retaining frame 14 along the length direction, and the weeding blade 7 is located directly above the tooth grooves 15 .

[0023] During the weeding process, the weeds will first be stuck in the corresponding grooves, which can prevent the weeds from shaking during the weeding operation, thereby affecting the weeding effect. At the same time, the grooves also play a role in protecting the weeding blade to a certain extent, preventing the weeding blade from directly colliding with hard objects such as stones hidden in the weeds during the weeding process.

[0024] In this structure, if Figure 1-2 A discharge rack 16 is provided on the rear end of the trolley 1 facing the retaining frame. A pair of front and rear rotating shafts 17 are rotatably provided on the discharge rack. A discharge belt 18 is provided between the rotating shafts 17. The discharge belt 18 is arranged to face backward and upward. The trolley 1 is also provided with a discharge motor 19 for driving the rear rotating shaft to rotate.

[0025] When the weeder is used for weeding, the cut weeds are thrown onto the discharging belt by the weeding cutter head, and the weeds are transported backwards by the discharging belt and fall onto the ground. In this structure, the discharging motor drives the discharging belt to rotate.

[0026] Further as a preferred structure, Figure 1-2 A pair of upper and lower pulleys 20 are provided on the middle connecting shaft 3, and linkage wheels 21 are provided on the connecting shafts 3 on both sides. The linkage wheels 21 are respectively covered with belts 22 with the corresponding pulleys 20. A driven wheel 23 is also provided on the left connecting shaft 3. The driving mechanism includes a reduction gear box 24 installed on the cart, and the output end of the reducer in the reduction gear box 24 is connected to the driving wheel 25. A driving belt 26 is provided between the driving wheel and the driven wheel.

[0027] During weeding, the drive mechanism rotates the three connecting shafts, driving all the weeding heads to achieve the desired weeding effect. In this structure, a pair of upper and lower pulleys are mounted on the central connecting shaft, while left and right connecting shafts are each equipped with a left and right interlocking pulley. Matching belts are secured between the upper and lower pulleys and the left and right interlocking pulleys. A driven pulley is also mounted on the left connecting shaft. Therefore, when the driven pulley rotates, the three connecting shafts rotate synchronously, driven by the belts. The driven pulley is driven by the reducer. Specifically, the reducer drives the driving pulley, which in turn rotates under the drive belt.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
