Description

Technical Field

[0001] This utility model belongs to the field of agricultural weeding equipment technology, specifically relating to vertical rotary weeding blades for dry and paddy fields. Background Technology

[0002] Weed control is a crucial step in agricultural production, directly impacting crop growth and yield. Currently, weeding methods include mechanical and chemical weeding. The use of chemical weeding methods has certain impacts on environmental protection, food safety, and the long-term sustainability of land. Furthermore, prolonged use of herbicides can lead to herbicide resistance in weeds and damage the soil's natural properties.

[0003] When using mechanical weeding, most weeding equipment is single-shaft driven, operating on a single blade. Due to the different soil characteristics of paddy fields and dry fields, a single blade has poor versatility for weeding different types of land. Dry field soil is hard, and ordinary blades are insufficient to cut weeds at their roots; while paddy field soil is soft and muddy, making it easier for the blades to remove weeds.

[0004] Therefore, this application proposes a vertical rotary weeding blade for dry and paddy fields to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems of excessive soil impact from existing chemical weed control methods and low weed control efficiency of mechanical weed control methods on different types of land.

A second transmission shaft is connected to each of the third and fourth driven gears.

[0013] Furthermore, the bottom end of the second drive shaft is connected to the weeding shovel via mounting bolts.

[0014] Furthermore, the frame includes a mounting plate, a steering mechanism, and anti-sinking wheels. The bottom of the mounting plate is provided with four anti-sinking wheels, each of which is connected to the mounting plate through the steering mechanism.

[0015] Furthermore, a visual sensing module is also provided at the bottom of the mounting plate.

[0016] Furthermore, the steering mechanism includes a slewing bearing, a drive gear, and a wheel mounting bracket. The anti-sinking wheel is rotatably mounted on the wheel mounting bracket, which is connected to the mounting plate via the slewing bearing. The external teeth of the slewing bearing mesh with the drive gear, and multiple soil-discharging shovels are evenly distributed around the circumference of the anti-sinking wheel.

[0017] Furthermore, the transmission mechanism includes a first motor, a second motor, a longitudinal guide rail, a first slider, a transverse guide rail, a second slider, and a tool mounting rod.

Detailed Implementation

[0033] 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.

[0034] 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.

[0035] Example 1, combined with Figures 1-5 This embodiment describes a vertical rotary weeding blade for both dry and paddy fields, comprising a frame 1, a transmission mechanism 2, a vertical weeding blade for paddy fields 3, and a vertical weeding blade for dry fields 4. The vertical weeding blade for paddy fields 3 or the vertical weeding blade for dry fields 4 is mounted on the frame 1 via the transmission mechanism 2, and the vertical weeding blade for paddy fields 3 or the vertical weeding blade for dry fields 4 is connected to the transmission mechanism 2 by bolts.

[0036] The vertical weeding blade 3 for paddy fields includes a first housing 31, a third motor 32, a first transmission shaft 36, and a weeding blade 37. The third motor 32 is installed inside the first housing 31. The actuator of the third motor 32 drives the first transmission shaft 36 to rotate. The weeding blade 37 is installed on the first transmission shaft 36. The weeding blade 37 is a spiral blade.

[0037] The dryland vertical weeding blade 4 includes a second housing 41, a fourth motor 42, a second transmission shaft 46, and a weeding shovel 48. The fourth motor 42 is installed inside the second housing 41, and the actuator of the fourth motor 42 drives the second transmission shaft 46 to rotate. The weeding shovel 48 is installed on the second transmission shaft 46, and the end of the weeding shovel 48 is machined with serrations.

[0038] Two sets of vertical weeding blades 3 for paddy fields or vertical weeding blades 4 for dry fields are installed at the bottom of each frame 1. The two sets of blades are staggered and can carry out weeding work on two rows at the same time.

[0039] When weeding paddy fields, two sets of vertical paddy field weeding blades 3 are installed at the bottom of the frame 1 through the transmission mechanism 2. The vertical paddy field weeding blades 3 can generate lateral or longitudinal displacement through the transmission mechanism 2. The first outer shell 31 of the vertical paddy field weeding blades 3 is connected to the transmission mechanism 2 through multiple bolts. The first outer shell 31 has a first motor mounting base 38 for installing a third motor 32. The execution end of the third motor 32 is connected to a first drive gear 33. When the first motor 32 is turned on, it drives the first drive gear 33 to rotate. The first drive gear 33 drives the two first driven gears 34 meshing with it to rotate. Each first driven gear 34 also drives the second driven gear 35 meshing with it to rotate. A first transmission shaft 36 is installed on both the first driven gear 34 and the second driven gear 35. The lower half of the first transmission shaft 36 is equipped with weeding blades 37. The weeding blades 38 are spiral teardrop-shaped blades.

[0040] When weeding, the tractor pulls the frame 1 to move. The anti-sinking wheels 12 on the frame 1 have evenly distributed soil-dispersing shovels 16 on the circumference to push away the mud and prevent the tractor from getting stuck. The first drive shaft 36 is inserted 20mm into the paddy field soil. The third motor 32 drives the first drive shaft 36 to rotate. The spiral design of the weeding blade 38 rotates and cuts while quickly floating the removed weeds to the water surface along the arc of the blade head, which is convenient for cleaning.

[0041] A soil retaining plate 39 is installed at the bottom of the first housing 31. The soil retaining plate 39 prevents soil from splashing between the weeding blade 37 and weeds during the weeding process. The soil retaining plate 39 is machined with multiple water pipe mounting holes 30. Each water pipe mounting hole 30 corresponds to a first drive shaft 36. A water pipe is installed in the water pipe mounting hole 30 and the water pipe is directed towards the weeding blade 37 to rinse it. When weeding in paddy fields for a long time, some grass roots or weeds will become entangled on the weeding blade 37. The indirect rinsing by the water pipe improves the weeding efficiency of the weeding blade 37.

[0042] When weeding in dry fields, first remove the vertical weeding blade 3 from the paddy field. Then, connect the second housing 41 of the vertical weeding blade 4 to the transmission mechanism 2 with multiple bolts. Inside the second housing 41, there is a second motor mounting base 47 for fixing the fourth motor 42. The actuating end of the fourth motor 42 is connected to the second driving gear 43. The fourth motor 42 drives the second driving gear 43 to rotate, thereby driving the two third driven gears 44 meshing with the second driving gear 43 to rotate. Each third driven gear 44 also drives the fourth driven gear 45 meshing with it to rotate. A second transmission shaft 46 is installed on both the third driven gear 44 and the fourth driven gear 45. The bottom of each second transmission shaft 46 is connected to the weeding shovel 48 by mounting bolts 49. The bottom of the weeding shovel 48 has serrations.

[0043] When weeding, the fourth motor 42 is turned on to drive all the second drive shafts 46 to rotate. The weeding shovel 48 is pushed 20mm into the dry field soil through the transmission mechanism 2. The serrated design of the weeding shovel 48 can effectively cut the roots of weeds while reducing rotational resistance.

[0044] Example 2, combined with Figure 1 , Figures 6-9 This embodiment describes a vertical rotary weeding blade suitable for both dry and paddy fields. The frame 1 has a mounting plate 10 with four sets of anti-sinking wheels 12 connected to its bottom. Each set of anti-sinking wheels 12 is connected to the mounting plate 10 via a steering mechanism 11. The wheel mounting frame 15 of the steering mechanism 11 serves as the main connection between the anti-sinking wheels 12 and the mounting plate 10. The upper end face of the wheel mounting frame 15 is rotatably connected to the mounting plate 10 via a slewing bearing 13. The external teeth of the slewing bearing 13 mesh with a drive gear 14, which is driven by a motor. Under the motor's drive, the drive gear 14 rotates the slewing bearing 13, thereby causing the anti-sinking wheels 12 to swing left and right, improving their adaptability when weeding in the field.

[0045] The transmission mechanism 2 connected to the mounting plate 10 includes a transverse transmission mechanism and a longitudinal transmission mechanism. The longitudinal transmission mechanism is mounted on the mounting plate 10, and the longitudinal guide rail 22 of the longitudinal transmission mechanism is fixed to the bottom of the mounting plate 10. The actuator of the first motor 20 passes through the mounting plate 10 and the longitudinal guide rail 22 and is connected to the lead screw in the longitudinal guide rail 22. The first slider 23 is connected to the lead nut in the longitudinal guide rail 22. The lead nut and the lead screw are connected in a cooperative manner. The first slider 23 is slidably connected to the longitudinal guide rail 22. When the first motor 20 rotates forward or reverses, it drives the first slider 23 to move longitudinally upward or downward.

[0046] The transverse guide rail 25 is connected to the first slider 23 via the adapter 24. The execution end of the second motor 21 is connected to the lead screw inside the transverse guide rail 25. The second slider 26 is connected to the lead nut inside the transverse guide rail 25. The lead nut and the lead screw are connected in cooperation. The bottom of the second slider 26 is fixedly connected to the prop mounting rod 27. The bottom of the prop mounting plate 27 is connected to the paddy field vertical weeding blade 3 or the dry field vertical weeding blade 4 via multiple bolts.

[0047] The horizontal and vertical transmission mechanisms of the transmission mechanism 2 drive the prop to move horizontally or vertically. In conjunction with the visual sensing module 5 set at the bottom of the mounting plate 10, the visual sensing module 5 is model MV-GE232GC-T-CL of Medvision. It can identify crops and weeds in the field. Through the action of the transmission mechanism 2, the blade will not damage the crops during the weeding process and can effectively clear the weeds in the field.

[0048] 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.
