Adjustable weeding device of rice transplanter

Abstract

The adjustable weeding device comprises a weeding part, a rack, wheels, single-wheel steering mechanisms, a power transmission device and a telescopic device, the single-wheel steering mechanisms are slidably arranged on the rack in a bilateral symmetry mode, the wheels are rotatably arranged on the independent steering mechanisms, the angles of the wheels can be changed, and the power transmission device is connected with the power transmission device. The weeding part comprises a plurality of groups of independent weeding wheels, two groups of independent weeding wheels are arranged on independent steering mechanisms on the left side and the right side, the independent weeding wheels rotate to weed the field surface, and the telescopic device comprises a universal shaft, a rotating shaft, a transmission gear set and a power shaft. The invention provides an adjustable weeding device of a rice transplanter, which can adjust the wheel track of the rice transplanter and the spacing of the weeding device, effectively adapt to rice seedling beds with different seedling spacing and perform weeding operation on the rice seedling beds, and can automatically circulate back, open and close in the adjusting process to improve the adjusting efficiency.

Description

technical field [0001] The invention relates to the technical field of rice transplanters, in particular to an adjustable weeding device for rice transplanters. Background technique [0002] With the improvement of our country's industrial level, farmland management has basically realized mechanized operations. When planting rice, rice transplanters are generally used for transplanting. However, due to different types of rice transplanters, the distance between the transplanted rice is not the same, resulting in multiple rice fields. The distance between the seedlings in the field is different, so when weeding the seedling field, the weeding mechanism cannot effectively match the row spacing of the seedlings, so that the seedlings are damaged during weeding, and it is difficult to realize mechanized operation, and the wheels of the rice transplanter are also easy to press the seedlings . Contents of the invention [0003] Aiming at the deficiencies in the prior art, the i...
