Description

Technical Field

[0001] The utility model belongs to the technical field of weeding devices, in particular to a weeding device. Background Art

[0002] In the process of agricultural production, it is necessary to remove weeds in the planting area. Specifically, since the weeds growing in the field are mostly herbaceous plants, their roots, stems and leaves are relatively soft and can be easily cut by a weeder during the weeding process.

[0003] Specifically, with the shift towards green production, mechanical weed control is more environmentally friendly than chemical weed control. Specifically, the use of agricultural herbicides not only damages the ecological environment but also easily pollutes the soil. This is especially true in green agriculture, where crop cultivation and animal husbandry are carried out simultaneously, such as raising fish and shrimp in rice fields, where herbicides cannot be used during the weeding process.

[0004] Mechanical weed control is often done with a cutting wheel. The drawbacks of this method include low weeding efficiency, the inability of the rotating wheel to mow large areas, and increasing the size of the cutting wheel inevitably increases the weight of the weed control equipment.

[0005] Therefore, the use of cutting wheels for weeding is not used in agricultural weeding. In agricultural production, weeds in the fields grow very lushly. Therefore, how to use a weeding device with high weeding efficiency and the ability to cut weeds over a large area is of great significance for improving agricultural production in order to quickly restore a weed-ridden planting field to a clean, weed-free state suitable for agricultural planting. Utility Model Content

[0006] Based on the above background, the purpose of the present invention is to provide a weeding device.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A weeding device comprises a frame base, one side of which is fixedly connected to a plurality of convex seat plates, and the convex seat plates are assembled and connected to a weeding assembly;

[0009] The weeding assembly includes a mounting frame, the mounting frame is rotatably connected to a rotating seat, the rotating seat includes an upper seat body and a lower seat body that can be detachably mounted on the upper seat body, and a plurality of cutting soft belts are assembled and connected between the upper seat body and the lower seat body;

[0010] The weeding assembly further includes a motor for driving the rotating seat to rotate;

[0011] The mounting frame plate and the boss plate are connected via a hinge structure;

[0012] The hinge structure includes a U-shaped frame fixedly connected to the inner end of the mounting frame plate, the inner side wall of the U-shaped frame is fixedly connected to a pair of hinged ears, and the convex seat plate is hinged in the hinged ears;

[0013] The U-shaped frame and the convex seat plate are locked by a locking structure, and the locking structure includes sliding openings respectively opened at the top and bottom positions of the U-shaped frame, and the top and bottom of the convex seat plate are respectively fixedly connected to fixing screws passing through the sliding openings, and the fixing screws are threadedly connected to locking nuts;

[0014] During the process of flipping the mounting frame plate, the U-shaped frame rotates relative to the fixed screw through the sliding adjustment port. After the angle is adjusted, it is locked and positioned on the U-shaped frame through the locking nut.

[0015] Preferably, the side walls of the upper and lower bodies facing each other are respectively provided with a card slot adapted to the cutting soft belt, and when the upper and lower bodies are combined, the cutting soft belt is limited in the card slot.

[0016] Preferably, a top edge portion of the lower seat is fixedly connected to a plurality of mounting screws penetrating the upper seat, and the mounting screws are slidably connected to the upper seat;

[0017] A fastening nut is threadedly connected to the mounting screw.

[0018] Preferably, the motor is fixedly mounted on the bottom of the mounting plate;

[0019] The output shaft of the motor is fixedly mounted at the bottom center of the lower seat body.

[0020] Preferably, a front support roller is installed on the left side of the bottom of the mounting frame plate.

[0021] Preferably, a plurality of rear balancing roller components corresponding to the front supporting rollers are fixedly connected to the right side wall of the frame seat.

[0022] Preferably, the rear balancing roller component includes a horizontal seat fixedly connected to the right side wall of the frame seat;

[0023] A rear balancing roller is installed at the bottom of the horizontal seat.

[0024] Preferably, the front supporting roller and the rear balancing roller both comprise a wheel frame, and the supporting roller is rotatably connected in the wheel frame;

[0026] Preferably, a push handle is fixedly connected to the top of the frame seat.

[0027] The utility model has the following beneficial effects:

[0028] 1. During operation, the motor is turned on. The juxtaposed mounting plate, rotating base, and cutting belt structure cause the rotating base to spin the cutting belt at high speed. When the cutting belt strikes the stem of a herb, it cuts and breaks the plant. Because the cutting belt is elastic and has a certain length, the high-speed rotation covers a wide area, effectively removing large areas of weeds.

[0029] 2. A locking structure allows the mounting plate, rotating seat, and cutting strip to be adjusted in angle and height. For example, by flipping the mounting plate, rotating seat, and cutting strip downward, plants near their roots can be cut off during weeding, improving the mowing effect. Specifically, the locking structure includes sliding openings at the top and bottom of the U-shaped frame. The top and bottom of the raised seat plate are fixedly connected to fixed screws that extend through the sliding openings, each of which is threaded with a locking nut. During the flipping of the mounting plate, the U-shaped frame rotates relative to the fixed screws via the sliding openings. After the angle is adjusted, the locking nut locks the frame into place on the U-shaped frame.

[0030] Specifically, after flipping, the top of the U-shaped frame is squeezed and locked by the upper locking nut, while the lower locking nut supports and locks the bottom of the U-shaped frame. After locking, the angle of the cutting belt changes, allowing the weeding process to cut plants of different heights, especially short young grass. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figure 1-5 As shown, a weeding device includes a frame base 1, and a left side wall of the frame base 1 is fixedly connected to a plurality of convex seat plates 21, and the convex seat plates 21 are assembled and connected with a weeding component.

[0043] Specifically, the weeding assembly includes a mounting plate 3, to which a rotating base 5 is rotatably connected. The rotating base 5 includes an upper base 51 and a lower base 52 to which the upper base 51 is detachably mounted. A plurality of cutting belts 53 are assembled and connected between the upper and lower bases 51, 52. The cutting belts 53 are elastic rubber belts with a circular longitudinal cross-section.

[0044] Specifically, slots A adapted for the cutting tape 53 are respectively defined on the mutually facing side walls of the upper and lower base bodies 51, 52. When the upper and lower base bodies 51, 52 are combined, the cutting tape 53 is retained within the slots A. A plurality of mounting screws 54 extending through the upper base body 51 are fixedly connected to the top edge of the lower base body 52. ​​The mounting screws 54 are slidably connected to the upper base body 51; fastening nuts are threadedly connected to the mounting screws 54.

[0045] Press the cutting strip 53 into the slot A of the lower base 52. Then, insert the mounting screw 54 through the through-hole of the upper base 51 and tighten the fastening nut. Because the cutting strip 53 is elastic, it remains firmly fixed between the upper and lower bases 51 and 52. This allows the cutting strip 53 to be removable and easily replaced.

[0046] The weeding assembly further includes a motor 55 for driving the rotating base 5 to rotate.

[0047] Specifically, motor 55 is fixedly mounted on the bottom of mounting frame 3; the output shaft of motor 55 is fixedly mounted at the bottom center of lower base 52. As with conventional methods, mounting frame 3 is equipped with a bearing that rotatably connects the output shaft of motor 55. As with conventional motor electrical connections, the motor is electrically connected to an external power source via power lines. As with conventional methods, the motors are connected in parallel and then electrically connected via power lines.

[0048] During operation, the motor 55 is turned on, and the juxtaposed mounting plate 3, rotating base 5, and cutting belt 53 structure cause the rotating base 5 to rotate at high speed, spinning the cutting belt 53 at high speed. When the cutting belt 53 strikes the stem of a herb, it cuts and breaks the herb. Because the cutting belt is elastic and has a certain length, the high-speed rotation can cover a wide area, thereby achieving large-scale weed removal.

[0049] Example 2

[0050] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 1. In order to achieve the cutting process, the angles of the rotating base 5 and the cutting soft belt 53 are adjusted, such as tilting the rotating base 5 and the cutting soft belt 53 downward, so that weeds of different heights can be removed by using the cutting soft belt 53, especially young grasses with smaller heights.

[0051] Specifically, the mounting frame plate 3 and the boss plate 21 are connected via a hinge structure.

[0052] Specifically, the hinged structure includes a U-shaped frame 4 fixedly connected to the inner end position of the mounting frame plate 3, the inner side wall of the U-shaped frame 4 is fixedly connected to a pair of hinged ears 42, and the convex seat plate 21 is hinged in the hinged ears 42; the convex seat plate 21 is hinged by a fixed pin shaft.

[0053] After the mounting frame plate 3 is turned over to adjust the angle of the mounting frame plate 3 , it is convenient to change the angles of the rotating seat 5 and the cutting soft belt 53 .

[0054] Specifically, the U-shaped frame 4 and the convex seat plate 21 are locked by a locking structure, and the locking structure includes sliding openings 41 respectively opened at the top and bottom positions of the U-shaped frame 4, and the top and bottom of the convex seat plate 21 are respectively fixedly connected with fixed screws 22 passing through the sliding openings 41, and the fixed screws 22 are threadedly connected with locking nuts 221; during the process of flipping the mounting frame plate 3, the U-shaped frame 4 rotates relative to the fixed screw 22 through the sliding openings 41, and after rotating to adjust the angle, it is locked and positioned on the U-shaped frame 4 through the locking nuts 221.

[0055] Specifically, after the U-shaped frame 4 is flipped over, the top of the U-shaped frame 4 is squeezed and locked by the upper locking nut 221 (as long as the locking nut 221 can be squeezed, it is locked), and the locking nut 221 at the lower end supports and locks the bottom of the U-shaped frame 4. After locking, due to the change in the angle of the cutting belt 53, specifically, the rotating base 5 and the cutting belt 53 are tilted downward by a certain angle, so that the young grass with a small height can be cut and removed.

[0056] Example 3

[0057] like Figure 1-5 As shown, this embodiment builds on the structure of Example 2, with a front support roller 13 mounted on the left side of the bottom of the mounting frame plate 3. Correspondingly, several rear balancing roller components corresponding to the front support rollers 13 are fixedly connected to the right side wall of the frame base 1. Specifically, the rear balancing roller components include a horizontal base 11 fixedly connected to the right side wall of the frame base 1; a rear balancing roller 12 is mounted on the bottom of the horizontal base 11.

[0058] Specifically, the front support roller 13 and the rear balancing roller 12 both include a wheel frame, in which a support roller is rotatably connected; the top of the wheel frame is fixedly installed by a mounting screw.

[0059] At the same time, the top of the frame seat 1 is fixedly connected with a push handle 6. During the weeding operation, the operator manually operates the push handle 6 to achieve weeding in the field with the entire device.

[0060] The above device is suitable for weeding dense fields, mostly herbaceous plants. For plants with harder stems, such as shrubs, traditional cutting wheels are required. Since most weeds in growing fields are herbaceous, this device can quickly and effectively weed a large area.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
