Description

Technical Field

[0001] The present invention mainly relates to the technical field of agricultural equipment, and specifically provides an agricultural weeding and fertilizing device. Background Art

[0002] Agricultural equipment refers to various machinery and tools used in the field of agricultural production. They can significantly improve agricultural production efficiency, reduce the labor intensity of farmers, and promote agricultural modernization. They mainly include seeders, transplanters, tillers, weeders, and sprinkler irrigation equipment, etc. These equipment play a crucial role in different links of agricultural production, contributing to the mechanization, automation, and intelligentization of agricultural production, and thus promoting the sustainable and healthy development of agriculture.

[0003] In the process of weeding and fertilizing vegetables, currently, weeders are generally used for weeding. However, even small weeders are used for regional weeding and are used before planting vegetables to clean the weeds on the land to facilitate subsequent vegetable planting. However, during the growth of vegetables, some weeds will occasionally grow in the soil, and these weeds are scattered among the vegetables rather than appearing in a regional manner. At this time, generally, workers need to manually remove the weeds. If a small weeder is used at this time, it will damage the vegetables during the weeding process. Since the weeds appear randomly and irregularly, workers need to frequently check and clean them, which cannot meet the unmanned supervision mode, is very inconvenient, time-consuming and laborious, and is not conducive to large-scale private planting. Summary of the Invention

[0004] The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single. Specifically, the present invention mainly provides an agricultural weeding and fertilizing device to solve the technical problem that during the vegetable planting process, some weeds often grow randomly among the vegetables, and currently, mainly workers manually remove the weeds, which requires frequent checking and cleaning, is very inconvenient, time-consuming and laborious as mentioned in the above background art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: An agricultural weeding and fertilizing device includes a support structure. The support structure includes two steel ropes distributed in parallel. A driving mechanism is jointly arranged on the two steel ropes. The driving mechanism includes an outer housing. A watering and fertilizing mechanism is arranged on the outer housing. A weeding mechanism is arranged inside the outer housing. The weeding mechanism includes a U-shaped bracket that can move up and down. Both ends of the U-shaped bracket are provided with lead screws. A nut seat and a limit seat on the nut seat are arranged on the lead screws. The limit seat is movably connected with a weeding wheel; The weeding wheel includes a ring body, and a plurality of V-shaped hook members with arc-shaped structures are arranged at equal intervals around the outer edge of the ring body. The V-shaped hook members can hook weeds from the ground, and a gear portion is arranged at the inner edge of the ring body.

[0006] Preferably, the limiting seat includes a mounting plate, and two limiting rings are arranged on the mounting plate. The gap between the two limiting rings is greater than the width of the gear portion, and the weeding wheel is located on the two limiting rings.

[0007] Preferably, a first motor is arranged on the mounting plate, and a driving gear is arranged at the output end of the first motor. The driving gear is meshed and connected with the gear portion.

[0008] Preferably, a second motor is arranged at one end of the lead screw, and the second motor is installed on the U-shaped bracket by bolts.

[0009] Preferably, stable telescopic rods are arranged at the four top corner positions on the upper side of the U-shaped bracket, and the upper end of each stable telescopic rod is connected to the upper side of the inner wall of the outer shell body by bolts.

[0010] Preferably, cylinders are arranged on both sides of the inner wall of the outer shell body, and the two cylinders operate synchronously. The output end of each cylinder is connected to the U-shaped bracket.

[0011] Preferably, a double-shaft motor is connected to the inside of the outer shell body by bolts. First rollers with annular grooves in the middle are arranged at the two output ends of the double-shaft motor. A second roller is arranged on one side of each first roller. The parts of the first roller and the second roller with annular grooves are both in rolling connection with the steel rope.

[0012] Preferably, the watering and fertilizing mechanism includes a water tank, a hanging plate and a transition box. The water tank is located on the upper side of the outer shell body. The transition box is installed on one side of the U-shaped bracket through the hanging plate and bolts. A plurality of drip pipes are linearly arranged at equal intervals on the lower side of the transition box. A connecting pipe is arranged on the upper side of the transition box.

[0014] Preferably, support frames are arranged at both ends of the steel rope, and the support frames are arranged on the ground.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention realizes the cleaning of weeds growing randomly between vegetables in the process of vegetable planting through the U-shaped bracket, stable telescopic rod, driving gear, cylinder, lead screw, nut seat, limit seat, weeding wheel, first motor and second motor. It does not require manual cleaning by staff, liberating the hands, saving time and effort, and also avoiding the situation that staff accidentally step on vegetables when cleaning weeds between vegetables. Moreover, due to the mutual cooperation between the ring body, gear part and V-shaped hook member, the weeds between vegetables can be directly hooked up. Compared with cutting, it can better avoid the regrowth of weeds in the same position, further improving the weeding effect.

[0016] (2)The present invention realizes watering and fertilizing the roots and leaves of vegetables in the process of vegetable planting through the water tank, hanging plate, transition box, connecting pipe, dropper and solenoid valve, providing two fertilization modes. When the dropper moves near the roots of vegetables, the fertilizer can be dissolved by the water in the soil through watering and then absorbed by the roots of plants. Root fertilization can directly promote the growth and development of plants. When the dropper moves to the leaf surface of vegetables, it can quickly supplement certain trace elements or nutrients to vegetables. Foliar fertilization can be directly absorbed by plants through the stomata on the leaves, following scientific fertilization principles and methods, which helps the healthy growth of vegetables, improving the yield and quality.

[0017] (3)The present invention realizes that the weeding wheel can linearly move back and forth on the vegetable planting plot through the support frame, steel wire rope, outer shell, dual-axis motor, first roller and second roller. And due to the mutual cooperation and information interaction between the camera and the motor, when weeds grow between vegetables are photographed and identified, the whole device is directly driven to move above the weeds for automatic cleaning, achieving an unattended mode, without the need for regular maintenance and cleaning by staff, which is beneficial to large-scale vegetable planting and improves the efficiency of vegetable planting.

The weeding wheel 36 includes an annular body 361. A plurality of V-shaped hook members 363 with arc-shaped structures are equidistantly arranged around the outer edge of the annular body 361. The V-shaped hook members 363 can hook weeds from the ground. And a gear portion 362 is arranged on the inner edge of the annular body 361.

[0025] Through the above structure, during the process of growing vegetables, it is realized that the weeds growing scattered among the vegetables can be cleaned in time, without manual cleaning by staff, liberating the hands, saving time and effort. Also, it avoids the situation that the staff accidentally step on the vegetables when cleaning the weeds between the vegetables. And it can be automatically cleaned, achieving a mode of unmanned supervision, which is beneficial to large-scale vegetable planting, improving the efficiency of vegetable planting. Moreover, it can also carry out drip irrigation, fertilization and watering, applying the fertilizer to the place close to the plant roots in the soil, which is beneficial to root absorption and effectively promotes the growth and development of plants.

[0026] The specific operation is as follows. When the camera 5 takes a picture and recognizes that there are new weeds growing among the vegetables, the dual-axis motor 22 starts, driving the first roller 23 to rotate. Then, the first roller 23 and the second roller 24 move along the steel rope 12, making the whole device move above the weeds. Then, the second motor 39 drives the lead screw 34 to rotate. Then, the nut seat 341 on the lead screw 34 adjusts the position of the weeding wheel 36, making the weeding wheel 36 located above the weeds. Then, the first motor 37 starts. By driving the engagement between the driving gear 38 and the gear portion 362, the weeding wheel 36 is driven to rotate clockwise. At the same time, the cylinder 33 pushes the U-shaped bracket 31 to move down. The fork openings of the V-shaped hook members 363 on the weeding wheel 36 will hook up the weeds. Then, the weeding wheel 36 moves up and resets. At the same time, the dual-axis motor 22 drives the first roller 23 to reverse, making the whole device reset to one end of the steel rope 12. If watering and fertilizing are needed, the solenoid valve 45 is opened. Then, the water in the water tank 41 flows out from the drip tube 44 through the connecting pipe 431 and the transition box 43. At the same time, the dual-axis motor 22 drives the whole device to move linearly. Among them, if watering the leaf surface, the cylinder 33 raises the drip tube 44 above the vegetable leaf surface. If watering the roots, the cylinder 33 moves the drip tube 44 down to near the vegetable roots.
