[0002] In agriculture, weeding is a time-consuming and labor-intensive process, especially in the cultivation of sweet corn. Weeding is particularly crucial because weeds compete with corn crops for nutrients, water, and sunlight, thus affecting the growth and yield of corn.

[0003] A search revealed Chinese Patent Publication No. CN217523742U, which discloses a weeding device for fresh corn cultivation, belonging to the technical field of weeding equipment. The device includes a support rod, one end of which is fixedly connected to a connecting structure. Rotating rods are rotatably connected to both ends of the connecting structure. Auxiliary wheels are mounted on the ends of the two rotating rods that are far apart from each other. Harvesting devices are mounted on both rotating rods. An equipment box is installed at the lower end of the support rod, and a drive motor is installed inside the equipment box. The drive motor can rotate the rotating rods, thereby using the harvesting devices to weed the ground.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] When adjusting the weeding blades to the soil depth, each blade needs to be adjusted sequentially, and then the bolts are tightened to limit the blade position. This process can easily lead to slow adjustment speed.

[0006] Therefore, in response to the above problems, the applicant provides a weeding device for fresh corn cultivation. Utility Model Content

[0007] To address the problems mentioned in the background section, this application provides a weeding device for fresh corn cultivation.

[0008] This application provides a weeding device for fresh corn cultivation, which adopts the following technical solution:

[0009] A weeding device for fresh corn cultivation includes a fixed block, on which a lifting mechanism is provided. The lifting mechanism includes a support plate and an "I"-shaped sliding column. Slide grooves are provided on both sides of the fixed block, and sliders are slidably connected to the two slide grooves. The sliders are fixedly connected to the corresponding sides of the support plate. An "I"-shaped slide groove block is fixedly connected to the top of the support plate. The support plate and the "I"-shaped slide groove block are slidably connected to the "I"-shaped sliding column. An "I"-shaped sliding column is fixedly connected to the top surface of the fixed block.

[0010] The fixed block is provided with a forward and reverse rotation mechanism, which includes a motor, a driving bevel gear, a driven bevel gear one, and a driven bevel gear two. The motor is bolted to the fixed block, and the rotating end of the motor is fixedly connected to the driving bevel gear. The driving bevel gear meshes with the driven bevel gear one and the driven bevel gear two.

[0011] Optionally, the fixing block has two motor slots, and a motor is placed in each of the two motor slots.

[0012] Optionally, it also includes a double-wheel connecting rod, which consists of double wheels and a connecting rod. The connecting rod is rotatably connected to the bearing plate, and the two ends of the connecting rod are fixedly connected to the double-wheel connecting rod.

[0013] Optionally, the "I"-shaped sliding block has a horizontally penetrating threaded hole, and the "I"-shaped sliding column has multiple threaded holes equidistantly opened. The threaded holes of the "I"-shaped sliding block and one of the threaded holes of the "I"-shaped sliding column are threaded together with a nut, and an inclined push handle is fixedly connected to one side of the bearing plate.

[0014] Optionally, a fixing rod and a connecting rod are fixedly connected to both sides of the corner of the fixing block, and a slider ring A and a slider ring B are fixedly connected to one end of the fixing rod and the connecting rod, respectively.

[0015] Optionally, a rotating rod is fixedly connected to the inner ring of the driven bevel gear one, and a weeding blade one is fixedly connected to one end of the rotating rod. A sleeve is fixedly connected to the inner ring of the driven bevel gear two, and a driven bevel gear two is fixedly connected to the middle of the sleeve. A weeding blade two is fixedly connected to one end of the sleeve, and the rotating rod passes through the sleeve.

[0016] Optionally, the rotating rod has a circular groove one, and the circular groove one is rotatably connected to a slider ring A; the sleeve has a circular groove two, and the circular groove two is rotatably connected to a slider ring B.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. This utility model, through the setting of the lifting mechanism, allows the nut to be unscrewed from the threaded holes of the "I"-shaped sliding block and the "I"-shaped sliding column, so that the bearing plate can slide up and down on the fixed block. The up and down movement of the bearing plate causes the double wheel connecting rod to move up and down synchronously. When the height of the double wheel connecting rod is raised, the first and second weeding blades will descend, and conversely, when the height of the double wheel connecting rod is lowered, the first and second weeding blades will rise above the ground. This achieves the advantage of quickly adjusting the first and second weeding blades, thus avoiding the trouble of adjusting each blade of the first and second weeding blades one by one.

[0019] 2. This utility model, through the setting of a forward and reverse rotation mechanism, uses a motor to drive the active bevel gear to rotate. The active bevel gear, along with driven bevel gear one and driven bevel gear two, rotate to achieve forward and reverse rotation. Driven bevel gear one rotates forward, driving the rotating rod to rotate forward, which in turn drives weeding blade one to rotate forward. Driven bevel gear two rotates in reverse, driving weeding blade two in reverse. The alternating operation of weeding blade one and weeding blade two ensures that weeds are cut from different directions in two adjacent cutting processes, thereby effectively reducing the phenomenon of missed cutting and double cutting.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This application discloses a weeding device for fresh corn cultivation.

[0028] like Figures 1-5As shown, a weeding device for fresh corn planting includes a fixed block 1, on which a lifting mechanism is provided. The lifting mechanism includes a support plate 3 and an "I"-shaped sliding column 4. Slide grooves 100 are provided on both sides of the fixed block 1. Slide blocks 2 are slidably connected to the two slide grooves 100. The slide blocks 2 are fixedly connected to the corresponding sides of the support plate 3. An "I"-shaped slide block 30 is fixedly connected to the top of the support plate 3. The support plate 3 and the "I"-shaped slide block 30 are slidably connected to the "I"-shaped sliding column 4. An "I"-shaped sliding column 4 is fixedly connected to the top surface of the fixed block 1.

[0029] The fixed block 1 is provided with a forward and reverse rotation mechanism, which includes a motor 11, a driving bevel gear 12, a driven bevel gear 13 and a driven bevel gear 17. The motor 11 is bolted to the fixed block 1, and the rotating end of the motor 11 is fixedly connected to the driving bevel gear 12. The driving bevel gear 12 meshes with the driven bevel gear 13 and the driven bevel gear 17.

[0030] Please see Figure 3 The fixing block 1 has two motor slots 101, and a motor 11 is placed in each of the two motor slots 101; the bolt-mounted motor 11 is shown in the figure.

[0031] Please see Figure 3 It also includes a double-wheel connecting rod 19, which is composed of double wheels and connecting rods. The connecting rod is rotatably connected to the bearing plate 3, and the two ends of the connecting rod are fixedly connected to the double-wheel connecting rod 19; the four double-wheel connecting rods 19 are in contact with the ground.

[0032] Please see Figure 2 The "I"-shaped sliding block 30 has a horizontally penetrating threaded hole, and the "I"-shaped sliding column 4 has multiple threaded holes equidistantly arranged. The threaded holes of the "I"-shaped sliding block 30 and one of the threaded holes of the "I"-shaped sliding column 4 are threadedly connected to a nut 5. An inclined push handle 6 is fixedly connected to one side of the bearing plate 3 at an angle. The vertical sliding cooperation between the sliding groove 100 and the slider 2 enables the bearing plate 3 to play a vertical limiting role during the up and down movement of the "I"-shaped sliding column 4. When the bearing plate 3 and the "I"-shaped sliding block 30 move upward in the "I"-shaped sliding column 4, the position of the bearing plate 3 can be positioned by the nut 5. At the same time, the rise of the bearing plate 3 causes the double wheel connecting rod 19 to rise accordingly.

[0033] Please see Figure 2 and Figure 4 The fixing block 1 has a fixing rod 7 and a connecting rod 9 fixedly connected to its two sides at the corner. One end of the fixing rod 7 and the connecting rod 9 is fixedly connected to a slider ring A8 and a slider ring B10, respectively. The fixing block 1 has a built-in charging module for supplying power to the two motors 11.

[0034] Please refer to Figure 4 The inner ring of the driven bevel gear one 13 is fixedly connected with a rotating rod 14, one end of the rotating rod 14 is fixedly connected with a weeding blade one 15, the inner ring of the driven bevel gear two 17 is fixedly connected with a sleeve 16, the middle part of the sleeve 16 is fixedly connected with the driven bevel gear two 17, one end of the sleeve 16 is fixedly connected with a weeding blade two 18, and the rotating rod 14 penetrates through the sleeve 16; by adjusting the depth of the weeding blade one 15 and the weeding blade two 18 with the ground, the depth of turning over the soil is increased, so that weeds with different root depths can be removed.

[0035] Please refer to Figure 4 A circular sliding groove one 140 is formed in the rotating rod 14, the circular sliding groove one 140 is rotationally connected with a sliding block ring A 8, a circular sliding groove two 160 is formed in the sleeve 16, and the circular sliding groove two 160 is rotationally connected with a sliding block ring B 10; the sliding block ring B 10 and the sliding block ring A 8 mainly play a role of limiting the positions of the rotating rod 14 and the sleeve 16, and at the same time, the circular sliding groove one 140 is rotated in the sliding block ring A 8 and the rotating rod 14 is prevented from moving left and right, and the circular sliding groove two 160 is rotated in the sliding block ring B 10 and the sleeve 16 is prevented from moving left and right.

[0036] The implementation principle of the weeding device for fresh corn planting according to the embodiment is as follows:

[0037] The motor 11 drives the driving bevel gear 12 to rotate, the driving bevel gear 12 rotates with the driven bevel gear one 13 and the driven bevel gear two 17 to realize forward and reverse rotation, the driven bevel gear one 13 drives the rotating rod 14 to rotate forward, the rotating rod 14 drives the weeding blade one 15 to rotate forward, the driven bevel gear two 17 drives the weeding blade two 18 to rotate reversely, and the weeding blade one 15 and the weeding blade two 18 rotate forward and reversely alternately, so that weeds can be cut from different directions in the adjacent two cutting processes, and the phenomenon of missing cutting and repeated cutting is effectively reduced.

[0038] When it is necessary to adjust the distance between weeding blade 15 and weeding blade 218 and the ground, simply unscrew the nut 5 from the threaded holes of the I-shaped sliding block 30 and the I-shaped sliding column 4. Then, the position of the bearing plate 3 on the fixed block 1 can be slid up and down. The up and down movement of the bearing plate 3 causes the double wheel connecting rod 19 to move up and down synchronously. When the height of the double wheel connecting rod 19 is raised, weeding blade 15 and weeding blade 218 will descend. Conversely, when the height of the double wheel connecting rod 19 is lowered, weeding blade 15 and weeding blade 218 will rise from the ground. Through the above operation, the height of weeding blade 15 and weeding blade 218 can be quickly adjusted, thus avoiding the trouble of adjusting each blade of weeding blade 15 and weeding blade 218 one by one. By adjusting the depth of weeding blade 15 and weeding blade 218 relative to the ground, the depth of soil turning can be increased, thereby removing weeds with different root depths.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
