Problems solved by technology

[0004] The structure of the above-mentioned weeding machine is complicated, which leads to more failures and delays the weeding efficiency; because this weeding machine uses the rotation of the disc to make the disc column directly eradicate weeds, it will cause mud and water and weeds to adhere and entangle on the disc column , which affects the cleaning rate of weeding; and the depth of the disc column and the paddy field ground cannot be adjusted, and the scope of application is limited

Embodiment Construction

[0021] Referring to Fig. 1 and Fig. 2, a kind of elastic tooth rice weeder is mainly composed of walking wheel 1, power transmission device 2, weeding device 3, lifting adjustment device 4, shield 5, grain divider 6 and other components. On the wheel shaft 101 of two walking wheels 1, the power transmission device 2 and the weeding device 3 shown in the double dotted line in the figure are fixedly connected, and the power transmission device 2 is connected with the front walking power output of the existing rice transplanter, and The weeding device 3 is connected through a chain drive, and the weeding device 3 is a spring-toothed rotating wheel structure. The spring teeth are driven by the power transmission device 2 to rotate and pop up weeds in the paddy field. Grass can not be stuck on the elastic teeth, which is conducive to improving the weeding cleaning rate. The weeding device 3 is provided with a shield 5; Adjust spring teeth to the depth of paddy field ground; Describ...

Abstract

The present invention belongs to the field of agricultural machinery, and is a kind of elastic tine type rice field weeder. The weeder includes walking wheel, rice straw separator, engine, driving unit fixed to the shaft of walking wheel, chain driven weeding unit, and elevating unit on the walking unit. Weeding with the elastic tine rotating wheel mechanically has low weeding cost, and is fast, efficiency and favorable to producing green rice product. The present invention has easily regulated depth of weeding and is suitable for matching with various type of rice seedling transplanting machines.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a spring-tooth rice weeder that uses spring teeth to rotate weeds in rice fields. Background technique [0002] In my country, weeding in rice fields is generally done with pesticides or manual weeding. Pesticide weeding can easily cause residual pesticide toxins in rice, cause public nuisance, cause side effects, and affect the utilization rate of organic fertilizers; manual weeding is time-consuming, laborious, low in efficiency, and high in cost. . In recent years, my country has advocated green agriculture, pollution-free crops, and the cultivation of pure green rice that meets international standards. Therefore, the use of pollution-free mechanized weeding is under development. [0003] A Chinese patent discloses "a power weeder for paddy fields", the authorized announcement number is CN2472465Y, the structure of the weeder is: a vertical frame is provided on the frame, a...
