Abstract

The invention belongs to the technical field of weed removing, and particularly discloses a stretchable hoe. The stretchable hoe comprises a hoe handle. The hoe handle comprises a fixed rod and a movable rod. A piston cavity is formed in the fixed rod, and a piston rod matched with the piston cavity is arranged on the movable rod; an air bag is arranged on the outer wall of the fixed rod and is bonded to the fixed rod; an air tap is arranged on the air bag, and a one-way valve is installed on the air tap; a ventilating groove communicated with the piston cavity is formed in the fixed rod, and the air tap is located in the ventilating groove. The stretchable hoe has the function that the length of the hoe handle can be adjusted according to the specific condition of an operator.

Description

Technical field [0001] The invention relates to the technical field of weed removal, in particular to a telescopic hoe. Background technique [0002] Heterosis breeding is the main method of vegetable breeding at present. There are many ways of seed production technology used in heterosis breeding, but no matter which way, they are inseparable from the cultivation of seedlings of parental plants (including self-incompatible lines, inbred lines and male sterile lines). In order to ensure the quality of hybrids, it is indispensable to strictly remove hybrids during the positive breeding period. For a large area of ​​the positive border, it is necessary to enter the border to pull out the miscellaneous plants. This working method is not only inefficient, but also easy to trample on the seedlings of other parents. [0003] At present, the main tool for removing impurities is a hoe, usually a hoe is composed of a hoe plate and a hoe target, and the hoe target is usually a tree stick. ...
