Embodiment Construction

[0018] Such as figure 1 , figure 2 and image 3 , A vibration-damping double pick includes: double pick head 1, pick handle 2, wedge block 3, metal wire 4, support tube 5, end cap 6, metal block 7, screw 8 and handle 9. The double pick head 1 is welded to one end of the pick handle 2, the pick handle 2 is made of an aluminum alloy tube, and the pick handle 2 is made of an aluminum alloy tube with a specification of φ20-32 mm and a length of 500-1500 mm; the wedge-shaped The block 3 is made of phenolic plastic, the cross section is circular, and the longitudinal section has a taper. The wedge-shaped block 3 is driven into the end of the pick handle 2 with the double pick 1, and the depth of penetration exceeds the length of the sleeve 1.1 in the double pick 1. The strength and stability of the pick handle 2 are enhanced to prevent the pick handle 2 from being deformed. The metal wire 4, support tube 5, end cap 6 and metal block 7 form a double dynamic shock absorber, and th...

Abstract

The invention discloses a vibration reduction dual-head pickaxe which comprises double pickaxe heads, a pickaxe handle, a wedge block, metal wires, a supporting pipe, end covers, metal blocks, a screwand a handle, wherein the double pickaxe heads are arranged at one end of the pickaxe handle; the pickaxe handle is made of an aluminum alloy pipe; the wedge block is arranged in an inner cavity at one end of the pickaxe handle, and the double pickaxe heads are arranged at the end of the pickaxe handle; the metal wires, the supporting pipe, the end covers and the metal blocks form a double dynamic vibration absorber, and one metal block, one metal wire, one end cover, the supporting pipe, the other end cover, the other metal wire and the other metal block are sequentially arranged; the handleis sleeved at a gripping end of the pickaxe handle; the handle, the pickaxe handle and the supporting pipe in the double dynamic vibration absorber are fastened together. The vibration reduction dual-head pickaxe is simple in structure and convenient in use; when the pickaxe is used for digging a pit, vibration can be reduced, arms are not vibrated, the pit digging efficiency can be improved, andthe planting quality is ensured.

Description

technical field [0001] The invention relates to the technical field of agricultural ditch digging tools, in particular to a vibration-damping double pick. Background technique [0002] When farmers plant kidney beans on their own private plots, they first set up a wide ridge, plan two rows of small pits with a pick, sprinkle 3 to 5 kidney bean seeds in each small pit, and cover them with soil. Kidney bean seedlings in the two rows of small pits are used to build a kidney bean frame, so that the kidney bean seedlings are ventilated, and it is easy to produce more kidney beans. In this work, although picks are used to plan small pits, but the number of pits is large, there will be impact vibration during the process of digging pits, and frequent digging operations for a long time will make the arms numb and uncomfortable; traditional picks are It is a single pickaxe, although it does not use much force to dig a small hole, but the work efficiency is low, and the distance betw...
