Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a reciprocating weeding blade for dry fields. Background Technology

[0002] In the cultivation of crops in dryland fields, weeds compete with crops for water, nutrients, and sunlight, severely impacting crop yield and quality. Therefore, weeding is a crucial aspect of dryland management. Currently, the main methods for weeding in dryland fields are as follows:

[0003] Manual weeding: Weeds are removed manually using tools such as hoes and sickles. Although this method can remove weeds accurately and cause little damage to crops, it is labor-intensive and extremely inefficient, making it difficult to meet the needs of large-scale agricultural production.

[0004] Chemical weeding: It kills weeds by spraying herbicides, which is highly efficient, but long-term use can lead to soil pollution, increased herbicide resistance in weeds, and may cause phytotoxicity to crops, which is not in line with the concept of green agriculture development.

[0005] In addition, the existing mechanical weeding equipment relies heavily on manual operation or simple mechanical steering, resulting in low steering accuracy and slow response. It lacks flexibility when operating in complex fields, leading to poor targeted weed removal.

[0006] Therefore, this application proposes a reciprocating weeding blade for dryland fields to solve at least one of the above-mentioned problems. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] 1. The reciprocating weeding blade of this utility model for dryland uses the cooperation of a first weeding blade fixed on the weeding blade mechanism and a second weeding blade that moves laterally in a reciprocating manner to cut weeds in multiple directions. It is especially suitable for dense weeds between plants and rows, and solves the problem of incomplete cutting in a single direction by traditional blades.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0029] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0030] Example 1, combined with Figures 1-4 This embodiment describes a reciprocating weeding cutter for dryland fields, which includes a frame mounting body 1, a transmission mechanism 4, and a weeding cutter mechanism 5. The weeding cutter mechanism 5 is mounted on the frame mounting body 1 via the transmission mechanism 4. The bottom of the frame mounting body 1 is also provided with multiple wheels 3.

[0031] The weeding blade mechanism 5 includes a third motor 51, a motor mounting base 52, a fixing plate 53, a first weeding blade 54, and a second weeding blade 55. The cylinder of the third motor 51 is mounted on the motor mounting base 52, and the fixing plate 53 is mounted on the motor mounting base 52. The first weeding blade 54 and the second weeding blade 55 are arranged sequentially below the fixing plate 53. The first weeding blade 54 is fixedly connected to the motor mounting base 52, and the second weeding blade 55 is connected to the third motor 51. The third motor 51 drives the second weeding blade 55 to reciprocate laterally.

[0032] When weeding, the frame mounting body 1 is connected to a tractor or other transport equipment, or the frame mounting body 1 is manually pushed to move in the field. The transverse transmission mechanism and the longitudinal transmission mechanism of the transmission mechanism 4 are used to drive the weeding blade mechanism 5 to move laterally or longitudinally. The third motor 51 is turned on, and the third motor 51 drives the drive gear 56 to rotate. When the drive gear 56 is meshed with the driven gear 57, it drives the driven gear 57 to rotate. The eccentric wheel 58 is coaxially set with the driven gear 57. During the rotation of the eccentric wheel 58, the second weeding blade 55 is driven to make a transverse reciprocating motion through the connecting rod 59. The weeds are in the gap after the second weeding blade 55 and the first weeding blade 54 are misaligned. The weeds are cut off by the transverse movement of the second weeding blade 55.

[0033] The first weeding blade 54 and the second weeding blade 55 have multiple slots 551 machined on them. The fixing plate 53, which is fixed to the motor mounting base 52 by bolts, has corresponding pin holes 531 machined on it. The fixing pins pass through the pin holes 531 and the slots 551 on the first weeding blade 54 and the second weeding blade 55 in sequence. With the cooperation of the pin and the slots 551, the lateral displacement of the second weeding blade 55 is limited, so as to prevent the second weeding blade 55 from falling off or cutting the crop due to excessive stroke.

[0034] Example 2, combined with Figures 1-6 This embodiment describes a reciprocating weeding blade for dryland fields. The bottom of the frame mounting body 1 is equipped with two sets of weeding blade mechanisms 5. Each set of weeding blade mechanisms 5 is mounted on the frame mounting body 1 via a transmission mechanism 4. The bottom of the frame mounting body 1 is also equipped with two sets of visual sensing modules 6. The model of the visual sensing modules 6 is MV-GE232GC-T-CL from Medvision. The visual sensing modules 6 are used to observe the distribution of crops and weeds in the field and control the lateral or longitudinal displacement of the weeding blade mechanisms 5 through the transmission mechanism 4, thereby improving weeding efficiency and avoiding damage to crops in the field.

[0035] The motor mounting base 52 of the weeding blade mechanism 5 is connected to the transverse slider 46 through the blade connector 47. The transverse slider 46 slides on the transverse slide rail 45. The transverse slide rail 45 is provided with a lead screw and a lead screw nut that are connected in a matching manner. The lead screw nut is connected to the transverse slider 46 and is used to drive the transverse slider 46 to make transverse displacement. The lead screw is connected to the second motor 44. When the second motor 44 is started, it drives the lead screw to rotate, thereby driving the weeding blade mechanism 5 to move laterally back and forth under the action of the lead screw nut and the transverse slider 46, avoiding the crops during the weeding process.

[0036] The transverse slide rail 45 is connected to the longitudinal slider 42 of the longitudinal transmission mechanism via the adapter 43. The longitudinal slider 42 slides on the longitudinal slide rail 41. The longitudinal slide rail 41 is equipped with a lead screw and a lead screw nut that are connected in a cooperating manner. The lead screw nut is connected to the longitudinal slider 41 and is used to drive the longitudinal slider 42 to make longitudinal displacement. The lead screw is connected to the first motor 40. The first motor 40 drives the lead screw to rotate, thereby driving the weeding blade mechanism 5 to move longitudinally and reciprocally under the action of the lead screw nut, the longitudinal slider 42 and the transverse sliding mechanism. During the weeding process, the depth of weed cutting can be controlled.

[0037] Four sets of wheels 3 are provided at the bottom of the frame mounting body 1. Each set of wheels 3 is connected to the frame mounting body 1 through a steering mechanism 2. The wheel mounting bracket 21 of the steering mechanism 2 is used to mount the wheels 3. The wheel mounting bracket 21 is connected to the frame mounting body 1 through a slewing bearing 22. The slewing bearing 22 has external teeth machined on it. The external teeth of the slewing bearing 22 are connected to the drive gear 23. The drive gear 23 is driven by a motor to control the wheel mounting bracket 21 to swing left and right, thereby causing the wheels 3 to swing left and right, realizing the overall steering of the frame mounting body 1. The steering angle can be precisely controlled by the motor speed.

[0038] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
