Embodiment 1

[0013] exist figure 1 In the first shown embodiment, the pneumatic power-assisted garden shovel includes a shovel head 1 and a shovel handle 2; the shovel handle 2 includes a slide chamber 21 and a compression chamber 22 from front to back; the compression chamber 22 stores compression air, and there is a valve 220 between the compression chamber 22 and the slide chamber 21, when the push rod 2201 of the valve 220 is pushed to the side of the compression chamber, the compressed air in the compression chamber 22 is filled into the valve through the valve 220 The shovel cavity 21; the shovel head 1 is connected to a spool 23 that can slide axially in the spool cavity 21 through the connecting column 11; the shovel 23 is provided with a thin hole 230 parallel to the axis to The gap between the slide plug 23 and the valve 220 is communicated with the outside world, and the total cross-sectional area of ​​the pores 230 is much smaller than the exhaust area of ​​the valve 220; The ...

Embodiment 2

[0018] for figure 2 The second embodiment shown is different from the first embodiment in that the shovel handle 2 also includes an air pump 24 integrated with the compression chamber 22 so that when the air pressure in the compression chamber 22 is low, , the compression chamber 22 is directly inflated and pressurized through the pump 24 ; at the same time, the entire shovel handle 2 is lengthened through the pump 24 .

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...
