Profile modeling cotton top-cutting machine

Abstract

The invention discloses a profile modeling cotton top-cutting machine comprising a suspending traction frame (5), a stand (4), a driving mechanism (2) and a rotating top-cutting knife (11). The profile modeling cotton top-cutting machine is characterized in that the stand is provided with a height-measuring sensor which comprises a downward-floating swing rod (8) and a sensing sliding plate (9); a top-cutting knife rest (1) hinged with the stand (4) is arranged at the other end of the stand (4); the rotating top-cutting knife (11) is arranged at the end part of the top-cutting knife rest (1); a top-cutting knife floating driving mechanism (3) is arranged between the top-cutting knife rest (1) and the stand (4); and the top-cutting knife rest (1) and the floating swing rod (8) are provided with connecting rods (10) and travel switches (6). Compared with the prior art, the invention has the advantages of simple structure, reliable work, stable performance, low construction cost and easy popularization and application, can measure and model cottons with different heights aiming at topographical conditions, and has high production efficiency and favorable application prospect.

Description

Technical field: [0001] The invention relates to a cotton topping machine, in particular to a profiling cotton topping machine, which belongs to the technical field of agricultural machinery. Background technique: [0002] At present, the topping treatment of cotton in foreign countries mainly adopts the method of drug control, while in China, the control of cotton topping is the key link in cotton production and planting. At present, the cotton topping work mainly relies on manual topping, and manual topping Topping has a large demand for labor force, high labor intensity, low efficiency, and bad working environment. At the same time, because the topping cannot be done in time, the growth of cotton is adversely affected, thereby reducing the output of cotton. However, with the advancement of science and technology and the attention to environmental pollution at home and abroad, cotton topping machines will replace drugs and become an indispensable machine in the cotton prod...

Problems solved by technology

[0003] The cotton toppers introduced in Chinese patents 200720127132.6 and 200720189855.9 reduce labor intensity and improve efficiency to a certain extent, but their working process relies on manual height measurement and lifting of the cutter, and the entire operation process still relies on manual control of the cutter. , reducing labor intensity and improving efficiency are limited

[0004] The automatic height-adjusting cotton topping machine disclosed in Chinese patent CN201078930 includes a fixed frame, a floating frame, a lifting mechanism between the fixed frame and the floating frame, a grain lifter, a rotary topping knife, and a hydraulic transmission mechanism. A suspension frame is provided on the fixed frame, and a lifting cylinder is arranged between the fixed frame and the floating frame. The automatic lifting system composed of controller and CPU has a very complicated mechanism and high cost, and there are certain difficulties in popularization.
