Spring plate-type deep-ploughing plow hook

Abstract

The invention discloses a spring plate-type deep-ploughing plow hook. The spring plate-type deep-ploughing plow hook includes a plow frame connecting plate and a plow hook body, the plow frame connecting plate is connected with a fixing plate, the plow hook body is fixed to a safety hook, the safety hook is hinged with the fixing plate, the fixing plate is provided with a spring plate corresponding to the safety hook, the fixing plate is connected with the safety hook through a connecting rod mechanism, the safety hook is provided with an approaching sensor corresponding to the spring plate, the spring plate is provided with a sensor plate corresponding to the approaching sensor, the plow hook body is provided with a warning device, and the warning device is electrically connected with theapproaching sensor through a control device. According to the plow hook, no pins need to be replaced, when a plowshare meets stones, the spring plate is bent backwards to pull a connecting rod to make the plow hook body unlocked, and the plow hook rotates backwards by 45 degrees to be separated from the stones, so that the use purpose is achieved; the operation cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a plow hook, in particular to a spring plate type deep plow hook. Background technique [0002] In agricultural production, deep plowing is used to loosen the land, because there are hidden stones in the land, especially in the cultivated land in mountainous areas. When pear birches encounter stones during operation, large pears will be damaged. In recent years, people have invented a broken safety plow .The safety pin is cut off when the plow encounters stones. This protects the large plow from damage, but the frequent pin breakage and the long time to replace the pin increase the operating cost and reduce the work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a spring plate type deep plow hook, which does not need to replace the pin. When the plow birch encounters a stone, the spring plate bends backward and pulls the connecting rod to unlock the plow hoo...
