Pneumatic power-assisting garden shovel

Abstract

The invention provides a pneumatic power-assisting garden shovel. The garden shovel comprises a shovel head and a shovel handle. The shovel handle comprises a sliding piston cavity and a compressing cavity from front to back; compressed air is stored in the compressing cavity, a valve stem is arranged between the compressing cavity and the sliding piston cavity, and when an ejector rod of the valve stem is ejected to the side of the compressing cavity, the compressed air in the compressing cavity is charged into the sliding piston cavity through the valve stem; the shovel head is connected with a sliding piston capable of axially sliding in the sliding piston cavity through a connecting pillar; thin holes parallel with the axial line are formed in the sliding piston, so that the gap between the sliding piston and the valve stem is communicated with the external world, and the total cross section area of the thin holes is much smaller than the air-discharging area of the valve stem; in appearance, the sliding piston cavity and the compressing cavity are connected into an integrated cylinder; an air-charging valve is arranged at the outer end of the compressing cavity. During job engineering, the pneumatic power-assisting garden shovel can form explosive impact force so that hard objects can be rapidly shoveled off; in this way, physical power is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a garden shovel. Background technique [0002] In the neighborhood of garden tools, the garden shovel is a commonly used tool, mainly used for digging pits or removing tough buried objects, such as tree roots, gravel, etc.; when removing tough buried objects, the current garden shovel usually needs to consume Large physical strength, and it is difficult to provide explosive impact force to tough objects by manpower, resulting in slow and laborious removal process and low efficiency. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a pneumatic assisted garden shovel, which can form an explosive impact force in the operation project, so that tough objects can be quickly removed, so as to save physical strength and improve efficiency . [0004] The technical solution adopted by the present invention to solve the techn...
