Abstract
Description
Technical Field
[0001] This utility model relates to the field of weeding equipment, and in particular to a weeding device for rice cultivation. Background Technology
[0002] Rice weeding equipment is used to remove weeds in the planting area before rice planting to prevent weeds from hindering rice planting. It is widely used in various rice planting situations.
[0003] However, when using weeding equipment, traditional equipment uses a fixed push-pull structure, which cannot adjust the push-pull angle according to the operator's height and terrain slope. Long-term operation can easily lead to back fatigue, and the muddy environment of paddy fields increases the operating resistance, resulting in significant labor consumption. In addition, the height of the weeding parts is fixed, making it difficult to match different growth stages of weeds. When weeding shallowly, weed roots are easily left behind and regenerate, and deep operation can easily damage the rice root system. As a result, existing equipment mostly relies on a single weeding method and cannot completely remove weeds. Utility Model Content
[0004] The main objective of this invention is to provide a weeding device for rice cultivation, which can effectively solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1-4 As shown, this is a weeding device for rice cultivation. Please refer to it carefully. Figures 1-4 The system includes a mounting bracket 1 and a movable wheel 2. The movable wheel 2 is movably mounted on the inner side of the mounting bracket 1. A shovel frame 3 is fixedly mounted on the rear inner side of the mounting bracket 1. A shovel plate 4 is fixedly mounted on the lower end of the shovel frame 3. Push-pull linkages 5 are movably mounted on both sides of the mounting bracket 1. A sliding sleeve 7 is movably mounted on the outer side of the push-pull linkage 5. A lifting mounting frame 8 is fixedly mounted on the lower end of the sliding sleeve 7. A weeding mechanism 10 is provided on the inner side of the lifting mounting frame 8.
[0020] Please refer to this carefully. Figure 1 and Figure 2 A positioning plate 17 is fixedly installed on the upper end of the mounting bracket 1. The positioning plate 17 is located on one side of the push-pull linkage 5 and is connected by a pin. A push-pull handle 6 is integrally formed on the upper end of the push-pull linkage 5.
[0021] Specifically, the push-pull linkage 5 rotates around the outside of the mounting bracket 1 to adjust the operating angle, and then inserts a pin to connect with the positioning plate 17 to achieve fixation. The device is pushed and pulled by the push-pull handle 6, and the entire device is moved by the rotation of the moving wheel 2.
[0022] Please refer to this carefully. Figure 1 and Figure 2 The sliding sleeve 7 slides up and down around the push-pull linkage 5, and the lifting mounting bracket 8 is located below the push-pull linkage 5.
[0023] Specifically, the overall height of the weeding frame 14 is adjusted by sliding the sliding sleeve 7 around the push-pull linkage 5.
[0024] Please refer to this carefully. Figure 4The weeding mechanism 10 includes an engine 11, a drive pulley 12, a rotating shaft 13, a weeding frame 14, a driven pulley 15, and a transmission belt 16.
