For example, the metal material may be stainless steel, iron, or the like. The metal shell is adopted to ensure the strength, the corrosion resistance and the like of the bamboo bag loosening device, and the damage of high-pressure gas to the structure of the gas production chamber is avoided. After the high-pressure gas is generated, the gas is preferentially flushed out of the plant root system or hardened soil with lower strength, namely the high-pressure gas is preferentially emitted out of the gas through holes 12.

The gas generating chamber 10, the handle 80, the connecting piece 30 and the ignition device 20 are arranged into a detachable structure, so that the assembly and the transportation are convenient, and after the gas generating pills in the gas generating chamber 10 are used, the bamboo bag loosening device can be reused by filling new gas generating pills.

Further, in the preferred embodiment, the power supply mechanism 23 includes a battery 24, such as a dry cell battery, a lead storage battery, a lithium battery, etc., and an electrical connector 25. One pole of the battery 24 is connected to the electrical socket 25 and the other pole is used to connect to the control switch 22. For example, the positive electrode of the battery 24 is connected to the contact base 25, the control switch 22 is a push button switch having a metal case, a metal spring 27 is provided between the metal case and the battery 23, and the control switch 22 is pressed to be connected to the negative electrode of the battery 24.

The housing 41 may be a thin plastic tube, a plastic film, a tin foil, a paper case, or the like, but is not limited thereto as long as it can contain the gas generating agent. After the gas generating agent is ignited by the electric igniter, the lightweight case 41 can be expanded to allow the gas to enter the gas chamber 11. The gas generating agent may be, for example, a gas generating pill for an automobile airbag, for example, guanidine nitrate is conventionally used as a combustible substance, and basic copper nitrate is conventionally used as an oxidizing agent. The specific components and preparation method of the gas generating agent are the prior art and are not described in detail herein. After the gas generating pills are ignited, violent oxidation-reduction reaction occurs, so that a large amount of gas is generated. When the gas-producing pills are in a relatively closed environment (root soil), a large pressure is generated after ignition. Preferably, the housing 41 has a flange, the bottom surface of the flange is abutted against the top surface of the gas generating chamber 10, when assembling, only the gas generating pill 40 needs to be inserted into the cavity of the gas generating chamber 10, and the flange is abutted against the nozzle of the gas generating chamber 10, so as to ensure that the gas generating pill 40 does not fall down and form a seal for the nozzle of the gas generating chamber 10.

In this embodiment, the conical head 50 seals the second end of the gas generation chamber 10 to ensure that the high-pressure gas does not escape from the second end but escapes from the sidewall of the gas generation chamber 10 through the gas passage hole 12. The taper angle of the conical head 50 is towards the end away from the gas generating chamber 10. By using the conical head 50, the bamboo bag loosening device 100 can be more easily inserted into the root system of a plant or hardened soil. Further preferably, the cone angle of the cone head 50 is 25-40 degrees, further preferably 30 degrees, and the cone angle is smaller, so that the cone head is more beneficial to being inserted into bamboo bags or hardened soil.

Further, the axial length ratio of the conical head 50 to the gas generation chamber 20 is 1:5-7, such as 1: 6. By adjusting the angle and the length of the conical head 50, the stability of insertion is ensured, and the product is prevented from being pushed out by gas during gas production.

Further, in the preferred embodiment, the gas generation chamber 10 and the conical head 50 are detachably connected. For example, in one embodiment, the second end 102 of the gas generating chamber 10 is internally threaded, the end of the conical head 50 adjacent to the gas generating chamber 10 is externally threaded, and the gas generating chamber 10 and the conical head 50 are threadedly coupled. The screw thread connection mode is adopted, the assembly and the transportation are convenient, and the replacement of parts is convenient.

In other embodiments, the connection manner of the cone head 50 and the gas generation chamber 10 may be welding, snap connection, or the like, as long as the fixing requirement of the cone head 50 and the gas generation chamber 10 can be satisfied.

Further, in a preferred embodiment, the gas generating chamber 10 is a cylindrical structure, which is more favorable for the gas generating chamber 10 to be inserted into the plant root system, such as into the bamboo bag. Further preferably, the length to diameter ratio (ratio of axial length to diameter) of the gas generation chamber 10 is 10: 0.6-2. The instantaneous pressure of the gas production pill can be controlled by setting a proper length-diameter ratio. The gas pressure is too high, which is easy to cause the growth of newly added plants around the root system of the plant, such as the newly added bamboo buds around the bamboo bag are damaged; if the gas pressure is too low, the root system of the plant cannot be burst, and the loose degree of the hardened soil is insufficient. Further, the ratio of the axial length of the gas generating chamber 10 to the axial length of the handle 80 is 1: 1-1.5. This ratio is more convenient for inserting the bamboo pocket loosening device into the bamboo pile.

Further, in a preferred embodiment, the bamboo bag loosening device further includes a limiting plate 60, and the limiting plate 60 is sleeved outside the gas generating chamber 10 and is located at one end of the gas generating chamber 10 close to the handle 80. The limiting plate 60 is used for limiting the bamboo bag loosening device to continue to move downwards, and when the bamboo bag loosening device is used, the limiting plate 60 is pressed through a heavy object, so that the bamboo bag loosening device is prevented from being separated from soil or a plant root system.

Further, in the preferred embodiment, the retainer plate 60 includes an annular plate 61 disposed coaxially with the gas generating chamber 10 and coaxially with the gas generating chamber 11, and the annular plate 61 is detachably connected to the gas generating chamber 10. For example, in the present embodiment, the inner wall of the annular plate 61 is provided with an internal thread, the connection between the gas generation chamber 10 and the annular plate 61 is provided with an external thread, and the annular plate 61 and the gas generation chamber 10 are connected by a thread.

The annular convex strips 62 are arranged, so that the strength of the limiting plate 60 can be improved.

Further, in the preferred embodiment, the outer wall of the gas chamber 11 is provided with a stop portion 70, and the stop portion 70 is in a reverse taper shape and includes a horizontal stop face 71 and a conical face 72 with a diameter gradually decreasing from the first end 101 to the second end 102 of the gas generation chamber 10. The inverted cone-shaped structure ensures that the gas generating chamber 10 can be smoothly inserted when the bamboo bag loosening device is inserted downwards, and the horizontal stop face 71 forms limit in the vertical direction in the gas bursting process, so that the gas generating chamber 10 is prevented from being flushed out by gas.

Further, in the preferred embodiment, the lower end surface of the annular plate 61 abuts against the stop surface 71 at the uppermost end of the gas chamber 11. The annular plate 61 is further provided with a fastener 63, the fastener 63 is screwed on the outer wall of the gas generating chamber 10, and the annular plate 61 is fastened on the stop face 71 by tightening the fastener 63. Further, the periphery of the fastener 62 is formed with a plurality of finger grooves for facilitating the application of force by the user.

Further, in the preferred embodiment, a plurality of stops 70 are spaced along the gas generation chamber 10 from the first end 101 to the second end 102. For example, 3, 4, 5, 6, etc. Preferably, the gas passing holes 12 are opened between two adjacent stoppers 70.

Further, in the preferred embodiment, a plurality of gas passing holes 12 annularly distributed along the cross section of the gas generating chamber 10 form a gas outlet portion 13, and a plurality of gas outlet portions 13 are arranged at intervals along the axial direction of the gas generating chamber 10. The number of the gas passing holes 12 of each gas outlet portion 13 may be 2, 3, 4, etc., but is not limited thereto.

Further, in the present embodiment, the distance between two adjacent gas outlet portions 13 is equal, and each gas outlet portion 13 has the same number of gas passing holes 12.

The operating principle of the bamboo bag loosening device 100 of the embodiment is as follows:

when the bamboo bag is used, the conical head 50 and the gas generating chamber 10 are inserted into the central position inside the bamboo bag through the conical head 50, and a relatively closed environment is formed around the gas generating chamber 10. After the switch base 26 is removed and the control switch 22 is pressed, the metal spring 27 contacts the battery 24, so that the battery 24 and the gas generating pill 40 are conducted. The battery 24 outputs current to the gas generating pills 40 to trigger the gas generating pills 40 to instantly generate a large amount of gas and form high-pressure gas with a certain pressure in a closed environment. High-pressure gas is flushed out from the gas through holes 12 to burst the bamboo pocket and loosen a large amount of hardened soil around the root system.
