Description

Technical Field

[0001] This utility model relates to the field of garden tools, and more specifically to a farmland weeding machine. Background Technology

[0002] In agricultural production, weeds are a significant factor affecting crop growth, especially tough weeds such as reeds and brambles, which have extensive root systems and sturdy stems, making them difficult to eradicate completely using traditional weeding methods. Traditional farmland weeding machines mostly use rotating blades or cutting discs, but these methods suffer from the following problems when dealing with tough weeds: poor weed control, incomplete cutting, and easy equipment damage. To address these issues, this application proposes a farmland weeding machine that guides weeds to gather and cut, effectively meeting the needs for removing tough weeds and improving weeding efficiency and quality. Utility Model Content

[0003] This utility model provides a farmland weeding machine, which has the beneficial effect of guiding weeds to gather and cut, effectively meeting the needs of removing hard weeds, and improving weeding efficiency and quality.

[0004] A farmland weeding machine includes a frame with wheels rotatably connected to the front, rear, and right sides of the frame. Two guide plates are symmetrically fixed to the left side of the frame. A Z-shaped frame is fixed to the frame between the two guide plates. Two motors are symmetrically fixed to the Z-shaped frame. The output shafts of the two motors are each fixed with a gear plate. The two gear plates are respectively attached to the inner wall of the right side of the two guide plates.

[0005] Both guide plates have an inwardly extending arc-shaped portion formed on their right sides.

[0006] The arc-shaped portion is concentric with the toothed disc on the same side.

[0007] Multiple inwardly inclined limiting plates I are fixed to the inner walls of both guide plates. Attached Figure Description

[0008] The present invention will now be described in further detail with reference to the accompanying drawings and specific implementation methods.

[0014] Figure 6 This is a schematic diagram of the corner plate.

[0015] In the diagram: frame 101; handlebar 102; wheel 103; guide plate 104; limit plate I 105; column rod 106; electric push rod 107; arc-shaped part 108; Z-shaped frame 201; motor 202; gear 203; top frame 204; corner plate 205; limit plate II 206. Detailed Implementation

[0016] See Figures 1 to 5 The diagram shows an embodiment of an effective cutting process for hard weeds according to the present invention.

[0017] A farmland weeding machine includes a frame 101, with wheels 103 rotatably connected to the front, rear, and right sides of the frame 101. Two guide plates 104 are symmetrically fixed to the left side of the frame 101. A Z-shaped frame 201 is fixed to the frame 101 between the two guide plates 104. Two motors 202 are symmetrically fixed to the Z-shaped frame 201. The output shafts of the two motors 202 are each fixed with a gear 203. The two gear 203 are respectively attached to the inner wall of the right side of the two guide plates 104.

[0018] The drive frame 101 moves, causing the two guide plates 104 and two geared discs 203 to move synchronously. The two motors 202 are energized and start, causing the two geared discs 203 to rotate in opposite directions. The two rotating geared discs 203 cut the weeds. During this process, as the frame 101 moves, the two guide plates 104 guide the weeds, guiding them towards the direction of the two geared discs 203 and gathering them together. The two rotating geared discs 203 cut the gathered weeds. The two guide plates 104 form a V-shape, and the V-shape allows the two guide plates 104 to gather more weeds.

[0019] Furthermore, some hard weeds will tilt when they come into contact with the rotating toothed disc 203, making it impossible for the toothed disc 203 to cut them effectively. However, the two guide plates 104 will restrict the tilting direction of the weeds and guide the weeds into the space between the guide plates 104 and the toothed disc 203. The two toothed discs 203 rotate in the direction of the two guide plates 104 respectively. Then, the rotating toothed disc 203 cooperates with the supporting action of the guide plates 104, so that the cutting force of the rotating toothed disc 203 can be effectively applied to the hard weeds, achieving effective cutting of the weeds.

[0020] See Figure 4 The diagram shows an embodiment of the complete cutting of weeds according to the present invention;

[0021] Both guide plates 104 have an inwardly extending arcuate portion 108 formed on their right sides;

[0022] The arc-shaped portion 108 is concentric with the toothed disc 203 on the same side;

[0023] The guide plate 104 and the toothed disc 203 are in a tangential point contact state, while the arc-shaped part 108 extends the effective contact surface between the toothed disc 203 and the guide plate 104, and the effective cutting surface becomes longer. This can fully cut the weeds that enter between the toothed disc 203 and the guide plate 104, avoiding incomplete cutting or incomplete cutting.

[0024] See Figure 4 The diagram shows an embodiment of the present invention that provides unidirectional guidance for weeds;

[0025] Multiple inwardly inclined limiting plates I105 are fixed to the inner walls of both guide plates 104;

[0026] It can guide the weeds that enter the inner side of the guide plate 104 in one direction, and at the same time make the weeds neatly gather inward, avoiding the irregular growth of weeds from tilting outward and making them impossible to cut effectively.

[0027] See Figure 6 The diagram shows an embodiment of weed diversion and guidance according to the present invention;

[0028] A top frame 204 is fixedly connected to the Z-shaped frame 201, and an angle plate 205 is fixedly connected to the top frame 204; both gear discs 203 are located inside the angle plate 205.

[0029] The surface of the angle plate 205 diverts the weeds that enter between the two guide plates 104 and directs them to both sides, further causing the weeds to move closer to the two guide plates 104, thereby guiding the weeds smoothly into the space between the toothed disc 203 and the guide plates 104 for cutting.

[0030] See Figure 6 The diagram shows an embodiment of effectively guiding the direction of weeds according to the present invention.

[0031] Multiple inwardly inclined limiting plates II 206 are fixed to the outer surface of the corner plate 205;

[0032] It can guide weeds that come into contact with the corner plate 205 in one direction, and at the same time make the weeds move neatly towards the guide plate 104, so as to avoid the irregular growth of weeds leaning outwards, which would make it impossible to effectively guide the direction of the weeds.

[0033] See Figure 5 The diagram shows an embodiment of the present invention that can cut weeds to different heights;

[0034] The vertical height of the toothed disc 203 is adjustable, thus enabling it to cut weeds to different heights.

[0035] See Figures 3 to 5 The diagram shows an embodiment of the adjustable toothed disc 203 according to the present invention.

[0036] A column rod 106 and an electric push rod 107 are fixedly connected to the frame 101. The Z-shaped frame 201 is slidably connected to the column rod 106, and the telescopic end of the electric push rod 107 is fixedly connected to the Z-shaped frame 201.

[0037] The extension or retraction of the electric push rod 107 causes the Z-shaped frame 201 to slide vertically on the column 106, thereby changing the vertical height of the Z-shaped frame 201 and the two toothed discs 203, so as to cut the weeds to different heights as needed.

[0038] See Figure 3 A schematic diagram of an embodiment of the present invention that is easy to operate by hand is shown.

[0039] A rod 102 is fixedly connected to the frame 101; this makes it easier for the operator to hold the lawnmower and then control the lawnmower to move and start mowing.

[0040] See Figure 2 The diagram shows an embodiment of the present invention that facilitates efficient cutting of weeds;

[0041] The end of the corner plate 205 points to the junction of the guide plate 104 and the toothed disc 203; thereby effectively guiding the weeds to the junction of the guide plate 104 and the toothed disc 203, which facilitates efficient cutting of the weeds.

[0042] Both ends of the electric push rod 107 are welded with flanges, and the electric push rod 107 is fixedly connected to the frame 101 and the Z-frame 201 by the flanges and screws.

[0043] One option for the electric linear actuator 107 is the JS-TGZ-U2, and other applicable models in the prior art can also be used.

[0044] The motor 202 is available in models Z1 to 112, and other applicable models in the prior art can also be used.
