Agricultural rotary cultivator tool shaft automatic welder

Abstract

The invention discloses an agricultural rotary cultivator tool shaft automatic welder which comprises a sequencer (2), a main frame (1), a shaft disc fixing device (3), a drive device (9), an attached rack (7), a tool apron automatic supply device (4), a movable welding gun (6), a fixing welding gun (10) and a shaft end fixing device (11). The drive device (9) is connected on the main frame (1) to drive the attached rack (7) to perform reciprocating linear movement. The attached rack (7) is provided with the tool apron automatic supply device (4) and the movable welding gun (6). The shaft end fixing device (11) is connected on a slide rail of the main frame (1) and capable of freely adjusting the distance with the shaft disc fixing device (3) to be adaptive to tool shafts (8) of different lengths. The fixing welding gun (10) is arranged front above the shaft end fixing device (11) and used for welding of shaft ends and shaft pipes of the tool shafts (8). The agricultural rotary cultivator tool shaft automatic welder is high in degree of automation, capable of achieving one-button operation, achieving multiple techniques including shaft disc sealing, shaft head sealing, tool seat distribution and welding. Compared with manual operation in the prior art, the agricultural rotary cultivator tool shaft automatic welder is capable of achieving operation accuracy which can not be achieved manually and improving speed greatly.

Description

technical field [0001] The invention relates to an automatic welding machine for the cutter shaft of an agricultural rotary tiller. The utility model belongs to the technical field of agricultural machinery, and is specifically related to the manufacturing technology of the cutter shaft of the agricultural rotary tiller. Background technique [0002] The agricultural rotary tiller is used for land cultivation. It is one of the most important equipments for modern agricultural production in my country, and the market demand is very large. The knife shaft is one of the main parts of the agricultural rotary tiller. It is welded by the shaft end, the shaft tube, the shaft disc and the knife seat. The knife seat is arranged in two helical lines, positive and negative, on the shaft tube. Through the rotation of the knife shaft, the rotary tiller knife fixed on it is driven to pulverize the soil. The known agricultural rotary cultivator cutter shaft is manufactured by manual weld...

AI Technical Summary

Problems solved by technology

The known cutter shafts of agricultural rotary cultivators use manual welding, which not only has high labor intensity and low work efficiency, but also has a large deviation in the welding position of the cutter seat, and the quality of the cutter shaft cannot be guaranteed.
