Description

Technical Field

[0001] The utility model relates to the technical field of rice planting, and in particular to a rice inter-cultivation weeding wheel. Background Art

[0002] Since rice is a high-yield crop, it is often valued by many countries, and its distribution range is constantly expanding. For example, rice agriculture in Egypt and Nigeria in Africa; Spain and Italy in Europe; Cuba, Venezuela, Brazil and other countries in the Americas also occupy a certain position. In the United States, large tracts of rice fields have been developed in the lower reaches of the Mississippi River, where scientific large-scale dryland direct seeding technology is used for production. Due to eating habits, most of the rice in the United States is exported. In the northern region of my country, low-temperature resistant varieties are selected and irrigated with groundwater, so that the distribution of rice has expanded northward to North China, Northeast China, and even Heilongjiang. At present, chemical weeding is widely used in rice planting, and physical weeding is relatively weak. There are few easy-to-use machines. Although some manufacturers are also trying to use mechanized physical weeding, active power is rare, mainly because its principle is complicated, resulting in complex shapes of its parts and high manufacturing costs. For example, some research institutions use 3D printing or casting to manufacture inter-row weeding knives. This method is very expensive and the properties of the material cannot be guaranteed.

[0003] The Chinese patent with the announcement number CN2843024Y discloses a rolling weeding wheel that can less disturb the soil and moves with the tractor by friction with the ground. The rolling weeding wheel is composed of an inner ring of the rolling weeding wheel, reinforcement ribs, a flat blade, an outer ring of the rolling weeding wheel, and a blade seat. The inner ring of the rolling weeding wheel and the outer ring of the rolling weeding wheel are connected by reinforcement ribs, and the flat blade is installed on the blade seat. Through experiments and theoretical calculations, it is determined that the radial angle between the flat blade and the rolling weeding wheel is 122-130°, which can not only make the flat blade penetrate the soil to a specified depth, but also have better soil picking performance after the blade penetrates the soil to a specified depth, making it easy to turn the grass roots from underground to the ground.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for weeding and cleaning weeds between rice plants during use, and selective cleaning is impossible. The use of the soil-digging method for cleaning will inevitably cause limitations to the equipment. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a rice inter-cultivation weeding wheel, which solves the problem in the related art that it is inconvenient to selectively clean the weeds between the rice inter-cultivation plants.

[0015] The working principle and beneficial effects of the utility model are:

[0028] In this embodiment, the coupling connector 4 extends to the outside of the horizontal square tube 1 and is connected to the horizontal square tube 1 through a bearing. A plurality of bolts are arranged in a circular distribution to facilitate the support work of the coupling connector 4.

[0029] In this embodiment, the plurality of wire cutters 5 are arranged and distributed in a circular shape, and the plurality of wire cutters 5 are respectively distributed between the plurality of bolts in pairs, which can facilitate the positioning and connection work of the wire cutters 5.

[0030] In this embodiment, the two bolts are in compression contact with the outer surface of the wire cutter 5 , and a plurality of clamping plates and limiting shells 8 are arranged in a circumferential distribution, which can facilitate the limiting of the wire cutter 5 .

[0031] In this embodiment, an adaptable dust cover 7 is fixedly connected to one side of the interior of the horizontal square tube 1. The adaptable dust cover 7 is adapted to the internal shape of the horizontal square tube 1, which can facilitate the fixed connection of the adaptable dust cover 7 and facilitate dust prevention work inside the device.

[0032] In this embodiment, the inner sides of the plurality of limiting shells 8 are fixedly connected to the outer surfaces of the plurality of clamping plates respectively, and the plurality of limiting shells 8 are hollow in shape, which can facilitate the movement of the limiting shells 8 .

[0033] In this embodiment, the plurality of limiting shells 8 are respectively located outside the plurality of steel wire cutters 5 , and the interiors of the plurality of limiting shells 8 are respectively in contact with the outer surfaces of the plurality of steel wire cutters 5 .

[0034] In this embodiment, a plurality of mounting holes are provided on the front side of the vertical square tube 2, and the connection between the horizontal square tube 1 and the vertical square tube 2 is in an L shape, which can facilitate subsequent installation work.

[0035] The wire cutter 5 is made of a steel wire with a certain elasticity, so the weeds can be removed while the rice can be retained by taking advantage of the fact that the rooting depth of weeds is shallower than that of rice.

[0036] When in use, firstly, the vertical square tube 2 needs to be installed and connected with the external equipment. When the installation is completed, the staff needs to turn on the motor 6. After turning on, the motor 6 will synchronously drive the coupling connector 4 to rotate through the output shaft. The coupling connector 4 will synchronously drive the movable rotating disk 3 to rotate during the rotation process. The movable rotating disk 3 will synchronously drive the installed bolts to rotate during the rotation process. The bolts will synchronously drive the wire cutter 5 to rotate during the rotation process. The wire cutter 5 will clean the weeds during the rotation process.

[0037] The shape of the wire cutter 5 has two important angles. The first is a backward tilt angle, which is to use the flexibility of the rice seedlings and the elasticity of the wire cutter 5 to let go of the rice seedlings when passing through the rice, without damaging the rice seedlings. The second is a rotational inclination angle. When the wire cutter 5 is working, it rotates to push the weeds between the plants to the rows, and the weeding wheel between the rows eliminates them. Therefore, the wire cutter 5 also has a retreat angle in the rotational direction, which can automatically let go of the rice seedlings when it hits them by using its elasticity and the flexibility of the rice seedlings, without damaging the rice seedlings.
