Abstract
Description
Technical Field
[0001] This utility model relates to the field of weeding device technology, specifically an agronomic weeding device. Background Technology
[0002] A weeding machine is an agricultural machine mainly used to remove weeds in farmland, forests, or horticultural areas. Its main components include a motor, a linkage structure, a weeding disc, and a handle. To further improve user safety during operation, existing technologies also disclose weed guards that are adapted to the linkage structure. When in use, the weed guards can shield soil and grass that are splashed toward the operator's standing position, thereby reducing the chance of debris hitting the operator and improving the safety of operation.
[0003] However, while external structures such as grass barriers and rack handles can produce some positive effects, they also have negative impacts on the overall use of the device. For example, during storage and transportation, these external structures result in the device occupying a large space and making it difficult to neatly store and move. Secondly, the rack handles have a large span and require both hands to operate, leaving the user's arms without rest and causing rapid physical exertion, which affects work efficiency. Utility Model Content

The threaded rod has two ends that pass through the front and rear ends of the slide groove and extend to the outside of the weeder body. Both ends of the threaded rod are threaded with limit nuts. When the two limit nuts are threadedly connected to the threaded rod, they can clamp and limit the adjusting plate and the threaded rod in a way that tightly fits the corresponding surface of the weeder body. The other end of the adjusting plate can be rotated and adjusted with the threaded rod as the rotation base axis. The adjusting plate, when adjusted to an inclined position, can provide top pressure support to the composite weed baffle plate that is perpendicular to the weeder body.
[0006] Preferably, the composite grass barrier includes a support frame, and a plurality of filter screens are fixedly nested inside the support frame, the surface of which is coated with a corrosion-resistant coating.
[0007] Preferably, the top inner side of the support frame plate is engaged with one end of the pin, and the other end of the pin is fixed to the surface of one end of the U-shaped rod. One end of the pin is set as a T-shaped structure and fitted with a torsion spring. When the torsion spring is not under force, it stores the elastic traction composite weed guard plate parallel to the outside of the bottom of the weeder body.
[0008] Preferably, both ends of the threaded rod are configured as T-shaped structures, and the inside of the adjusting plate is provided with a through-shaped weight-reducing groove.

[0023] 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.
[0024] Please see Figure 1 and Figure 8 An agricultural weeding device includes a weeding machine body 1, a blade disc 2 connected to the weeding machine body 1 via a transmission, a U-shaped rod 3 fixed to the bottom surface of one side of the weeding machine body 1, and a composite weed baffle 4 hinged to one end of the U-shaped rod 3 via a pin. The composite weed baffle 4 can be flipped and expanded or stored parallel to the outside of the weeding machine body 1 under the support of the U-shaped rod 3. The composite weed baffle 4 includes a support frame plate, and several filter screens are fixedly nested inside the support frame plate. This reduces the weight of the overall structure of the composite weed baffle 4 while ensuring the shielding and protection effect of the composite weed baffle 4, and optimizes the use effect. The surface of the filter screen is coated with a corrosion-resistant coating to extend its service life.
[0025] The top inner side of the support frame plate is engaged with one end of the pin, and the other end of the pin is fixed on the surface of one end of the U-shaped rod 3. One end of the pin is set as a T-shaped structure and fitted with a torsion spring 5. When the torsion spring 5 is not under force, it will keep the elastic traction composite weed baffle 4 parallel to the outside of the bottom of the weeder body 1. The torsion spring 5 can ensure the stability of the composite weed baffle 4 parallel to the outside of the weeder body 1 by elastic traction, thereby reducing the footprint of the overall device.
[0026] The bottom surface of the weeder body 1 has a spatially interconnected storage groove 6 and a sliding groove 7. An adjusting plate 8 is installed inside the storage groove 6, and a threaded rod 9 is fixedly connected to one end of the adjusting plate 8. The two ends of the threaded rod 9 pass through the front and rear ends of the sliding groove 7 and extend to the outside of the weeder body 1. The surfaces of both ends of the threaded rod 9 are threaded with limit nuts 10. When the two limit nuts 10 in the opposite position are threadedly connected to the threaded rod 9, they can clamp and limit the adjusting plate 8 and the threaded rod 9 in a way that tightly fits the corresponding surface of the weeder body 1. The other end of the adjusting plate 8 can be rotated and adjusted with the threaded rod 9 as the rotation base axis. The adjusting plate 8 adjusted to an inclined position can provide top pressure support for the composite weed baffle 4 that is perpendicular to the weeder body 1.
[0027] Both ends of the threaded rod 9 are designed with a T-shaped structure to prevent the limit nut 10 from separating from the threaded rod 9 during reciprocating use, thus optimizing the performance. In addition, the inside of the adjusting plate 8 is provided with a through-shaped weight-reducing groove to ensure the structural strength while reducing its own weight.
[0028] The front and rear surfaces of the other side of the weeding machine body 1 are provided with screw holes, and a curved handle 11 is connected to the screw hole by a thread. A rubber sleeve is nested on the surface of the curved handle 11 away from the weeding machine body 1 to improve the comfort of gripping and applying force.
[0029] A transition sleeve 12 is fixedly fitted on the other side surface of the weeding machine body 1, and positioning rings are fixed on both ends of the transition sleeve 12. A sling 13 is installed between the two positioning rings, so that the whole device can be suspended on the user's shoulder for relatively labor-saving use.
[0030] In use, flip the composite weed barrier 4 so that it is perpendicular to the weeder body 1 under the support of the U-shaped rod 3 and the pin. Simultaneously, the torsion spring 5 deforms under force. To ensure the stability of the composite weed barrier 4 after flipping, tighten the corresponding limit nuts 10 at both ends of the threaded rod 9 to temporarily move the two limit nuts 10 away from the weeder body 1, releasing the restriction on the adjusting plate 8. Flip the adjusting plate 8 so that the other end of the adjusting plate 8 is flipped out from inside the storage slot 6. Then, the adjusting plate 8 drives the threaded rod 9 and the limit nuts 10 along... The sliding groove 7 is moved downward until one end of the adjusting plate 8 presses against the inner wall of the middle part of the composite weed barrier 4 and applies pressure, thereby ensuring the stability of the composite weed barrier 4 in subsequent use. Then, the two limit nuts 10 are reset and locked to limit and lock the adjusting plate 8 again. Then, the sling 13 is put on the operator's shoulder and the two curved handles 11 are held. The weeding machine body 1 is turned on and the weeding machine body 1 drives the blade 2 to rotate. Then the operator moves the whole device and puts the blade 2 close to the ground to cut and clean the weeds.
[0031] When operating with both hands for extended periods or when the operating space is limited, the adjustment plate 8 can be used as a handle for one-handed operation. The specific operation is as follows:
[0032] Tighten the corresponding limit nuts 10 on both ends of the threaded rod 9 to temporarily move the two limit nuts 10 away from the weeder body 1, release the limit on the adjusting plate 8, flip the adjusting plate 8 so that the other end of the adjusting plate 8 is flipped out from inside the storage slot 6, and the adjusting plate 8 is flipped towards the other side of the weeder body 1. After the adjusting plate 8 is flipped to a suitable angle, reset and lock the two limit nuts 10 to lock the adjusting plate 8 again. Then, twist and remove the two curved handle rods 11 or rotate and adjust the curved handle rods 11 to a position parallel to the weeder body 1. Then, put the sling 13 on the operator's shoulder and hold the adjusting plate 8 with one hand. The other side of the weeder body 1 can be placed on the operator's shoulder for pressure distribution. Then, turn on the weeder body 1, and the weeder body 1 drives the blade 2 to rotate. Then the operator moves the whole device and puts the blade 2 close to the ground to cut and clean the weeds. During the subsequent continuous operation, the operator can use both hands alternately.
