[0055] Embodiment

[0056] First of all, it should be noted that the present application is further improved and developed by the applicant on the basis of the prior application of the inventor, in order to overcome the shortcomings of the prior application;

[0058] But there is still the following insufficient in actual use: first, only single material can be sprayed in the process of spray mixing; spray mixing different materials needs to be reloaded and then spray mixed and applied, and the operation is complicated; second, when spray mixing different materials for the same spray point, spray mixing amount and spray mixing depth are not easy to control; third, shock wave and material input are carried out in two steps, in actual use process, shock wave is used to form crack in land first, then material is suspended and transported, and then shock wave is used to impact again, so as to transport material into the formed crack, and the efficiency is low, and the energy consumption in process is large.

[0059] In addition, the utility model discloses a kind of gas pressure series active devices for applying material to deep soil, the device includes material application gun, gas spray explosion system and material application system are connected with material application gun, gas spray explosion system and material application system are connected with material application gun in series, wherein, the gas spray explosion system includes spray explosion generator, the material application system includes material bin, feed valve, valve 1, material sending bin, valve 2 and material pipe connected with each other in sequence, the material pipe is inserted into high-pressure gas tank interior and is connected with its bottom in communication.The utility model device can uniformly apply quantitative various materials to the inside of soil layer of any depth, replace traditional mode, greatly improve the operation efficiency of material application to deep soil layer, significantly reduce the cost of material application to deep soil layer, reduce manual labor intensity.

[0060] But its actual use still has the following shortcomings: first, only single material spraying can be carried out during spraying; different materials need to be reloaded before spraying, which is complicated to operate; second, when spraying different materials at the same spraying point, the spraying amount and spraying depth are not easy to control; third, the time interval between the shock wave explosion soil loosening process and the material pre-spraying is relatively long, and the soil cracks formed by soil loosening are easy to recover, which is not conducive to the subsequent mixing of materials into the soil cracks, increasing the difficulty, uniformity and distribution range of the material distribution into the soil cracks.

[0061] Based on the defects of the prior application, the embodiment provides a gas-material mixed spraying executor, please refer to Figures 1-11 which comprises a material mixed spraying pipe 100, a material temporary storage assembly 200, a pressure material supply assembly 300, a second material supply assembly 400 and a gas supply assembly 500.

[0062] Among them, one end of the material mixed spraying pipe 100 has a material outlet 110; the material temporary storage assembly 200 is arranged at the end of the material mixed spraying pipe 100 away from the material outlet 110, for temporarily storing materials; the second material supply assembly 400 is in communication with the material temporary storage assembly 200, for conveying materials to the material temporary storage assembly 200; the gas supply assembly 500 is in communication with the material temporary storage assembly 200, for providing high-pressure gas for forming cracks or lifting effect of soil; and cooperating with the material temporary storage assembly 200, the materials temporarily stored in the material temporary storage assembly 200 are synchronously conveyed to the cracks.

[0063] It should be noted that the purpose of the material temporary storage assembly 200 is to temporarily store materials, and when needed, the materials can be discharged into the material mixed spraying pipe 100 for material conveying.

[0064] The second material supply assembly 400 can be used to first convey the material to be conveyed to the material temporary storage assembly 200, and then the gas supply assembly 500 can convey high-pressure gas to the temporary storage assembly at the same time, and the temporary storage assembly is opened to make the high-pressure gas and the material synchronously enter the material mixed spraying pipe 100, so that the high-pressure gas carries the material to move synchronously, and the soil is impacted to form cracks at the same time, and the material is distributed in each crack.

[0065] Through the above arrangement, the material and the high-pressure gas can move synchronously, so that one impact can realize the impact of the soil to form cracks and the conveying of the material to each crack, thereby improving the work efficiency while reducing the energy consumption; in addition, the design of the second material supply assembly 400 can increase the storage capacity of the material, thereby further improving the application range of the device.

[0066] Overall, the gas-material mixed spraying executor provided by the embodiment of the application can realize large-scale and rapid suspension conveying and residence of materials in the deep soil, improve the work efficiency, and effectively improve the utilization rate of materials and energy.

[0067] Specifically, the material conveyed in the embodiment can be compound fertilizer, organic fertilizer, biogas slurry, and modifier, etc., and the material can be in solid powder or liquid state. However, the device can also be used to convey other materials such as soil in actual use, which is within the protection scope of the application.

[0068] In addition, it should be noted that the connection between the second feeding assembly 400 and the material mixing and spraying pipe 100 adopts a parallel connection mode, which can further increase the storage capacity of the material and is suitable for large-area continuous fertilization.

[0069] Further, in order to enable the material temporary storage assembly 200 to better cooperate with the second feeding assembly 400 and the gas supply assembly 500, in the embodiment, the material temporary storage assembly 200 includes a shell 210 and a rotating core 220, the shell 210 is arranged in the material mixing and spraying pipe 100, and the shell 210 is respectively provided with a first through hole 230, a second through hole 240 and a third through hole 250 which are in communication with the material mixing and spraying pipe 100, the second feeding assembly 400 and the gas supply assembly 500.

[0070] The rotating core 220 is rotatably arranged in the shell 210, the rotating core 220 has a temporary storage cavity, the rotating core 220 is provided with a first central hole 270 and a second central hole 280 which are in communication with the temporary storage cavity, and the central axes of the first central hole 270 and the second central hole 280 coincide.

[0071] During rotation of the rotating core 220, the temporary storage cavity can be in communication with the pressure feeding assembly 300, the gas supply assembly 500 and the material mixing and spraying pipe 100.

[0072] Specifically, the central axes of the first through hole 230 and the third through hole 250 coincide, and the central axes are located in a vertical plane, and the central axis of the second through hole 240 is perpendicular to the central axis of the first through hole 230.

[0073] In the specific implementation process, the shell 210 can be in a hollow spherical shape.

[0074] Specifically, the shell 210 is provided with a rotating motor for driving the rotating core 220 to rotate.

[0075] It should be noted that the outer wall of the rotating core 220 is in gapless contact with the inner wall of the shell 210, so as to ensure the sealing property of the contact.

[0076] Through the above design, the temporary storage cavity can be communicated with the second feeding assembly 400, the gas supply assembly 500 and the material mixing and spraying pipe 100 through the rotation of the rotating core 220. When the rotating core 220 is rotated to the first central hole 270 or the second central hole 280 to be communicated with the second feeding assembly 400, the inner wall of the rotating core 220 closes the third through hole 250 and the first through hole 230 at this time, and the second feeding assembly 400 can be used to deliver the material to the temporary storage cavity. When the rotating core 220 is rotated to the first central hole 270 or the second central hole 280 to be communicated with the first through hole 230 and the third through hole 250 respectively, at this time, the gas supply assembly 500 releases a high-pressure shock wave, which passes through the temporary storage cavity into the material mixing and spraying pipe 100, and synchronously carries the material in the temporary storage cavity into the material mixing and spraying pipe 100, while impacting the soil to form a crack, so that the material synchronously enters the crack.

[0077] Further, in order to be able to improve the space of the temporary storage cavity, in the embodiment, the temporary storage cavity has a recessed area 291 on one side.

[0078] Specifically, in order to ensure the rotation efficiency of the rotating core 220, in the embodiment, the shell 210 and the rotating core 220 are preferably designed in a spherical shape.

[0079] Specifically, the second feeding assembly 400 includes a second conveying pipe 410, a second material hopper 420 and a second conveying device 430. One end of the second conveying pipe 410 is communicated with the second through hole 240, the second material hopper 420 is communicated with the second conveying pipe 410, and is used to deliver the material to the second conveying pipe 410. The second conveying device 430 is used to deliver the material in the second conveying pipe 410 to the temporary storage cavity.

[0080] In the embodiment, the second conveying device 430 can adopt two implementation modes:

[0081] The first mode: the second conveying device 430 includes a cylinder body 432 and a piston 433 arranged in the cylinder body 432. One end of the piston 433 is provided with a push rod 434, the push rod 434 is transitionally matched with the second conveying pipe 410, and the length of the push rod 434 is greater than the length of the second conveying pipe 410.

[0082] It should be noted that the transitionally matched means that the outer diameter of the push rod 434 is the same as the inner diameter of the second conveying pipe 410, and the push rod 434 can move in the axial direction of the second conveying pipe 410.

[0083] This way is to use the push rod 434 to push the material, and use the push rod 434 to control the opening and closing of the intersection of the second conveying pipe 410 and the second material hopper 420. When the end of the push rod 434 moves to the side of the second conveying pipe 410 away from the temporary storage cavity, the second conveying pipe 410 is in communication with the second material hopper 420 at this time, and the material in the second material hopper 420 enters the second conveying pipe 410 under the action of gravity. Then the push rod 434 moves towards the side of the temporary storage cavity, pushing the material in the second conveying pipe 410 while the side wall of the push rod 434 can seal the port of the second material hopper 420, thereby stopping the feeding. Repeat the above process to achieve the feeding.

[0084] The second way: the second conveying device 430 includes a second ball valve 431, a cylinder body 432 and a piston 433 arranged in the cylinder body 432; the second ball valve 431 is arranged in the second conveying pipe 410, and the second ball valve 431 can be in communication with the second material hopper 420;

[0085] The cylinder body 432 is located at the end of the second conveying pipe 410 away from the temporary storage assembly, and the piston 433 is provided with a push rod 434 at one end. The push rod 434 is in transition fit with the inner cavity of the second ball valve 431, and the length of the push rod 434 is greater than the length of the second conveying pipe 410;

[0086] This way is to use the second ball valve 431 to control the conveying of the material in the second material hopper 420. When the second ball valve 431 is rotated to be in communication with the second material hopper 420, the material in the second material hopper 420 enters the inner cavity of the second ball valve 431. When the second ball valve 431 is continuously rotated to be in communication with the second conveying pipe 410, the push rod 434 pushes the material in the inner cavity to the temporary storage cavity. In this embodiment, this scheme is preferred.

[0087] The purpose of the above two ways is to first quantitatively convey the material in the second material hopper 420 to the second conveying pipe 410, and then use the push rod 434 to push. The only difference is the way of implementation. All other schemes covered in this scheme should be understood as being within the protection scope of the present application.

[0088] Further, in order to be able to convey multiple materials alternately, the pressure feeding assembly 300 is specially added in this embodiment, and the shell 210 is provided with a fourth through hole 260 in communication with the pressure feeding assembly 300. During the rotation of the rotating core 220, the temporary storage cavity can be in communication with the pressure feeding assembly 300.

[0089] Specifically, the pressure feeding assembly 300 comprises a first material hopper 310, a pressure conveying device 320 and a first conveying pipe 330, the first material hopper 310 is in communication with the first conveying pipe 330 and is used to convey the material to the first conveying pipe 330, one end of the first conveying pipe 330 is in communication with the fourth through hole 260 and the other end is in communication with the pressure conveying device 320 so as to convey the material to the temporary storage cavity.

[0090] Specifically, the first conveying pipe 330 is provided with a control valve 340.

[0091] In addition, the central axis of the fourth through hole 260 coincides with the central axis of the second through hole 240 and they are respectively located on the two sides of the housing 210 in the horizontal direction, and the first through hole 230 and the third through hole 250 are respectively located on the two sides of the housing 210 in the vertical direction.

[0092] In the embodiment, the control valve 340 can adopt the form of a two-way rotary ball valve, and the communication is realized by rotating,

[0093] In addition, in the embodiment, the pressure conveying device 320 can adopt various implementation manners capable of providing pressure such as air pumps, which can be referred to the conventional prior art and will not be described here.

[0094] In addition, in order to enable the rotating core 220 to better cooperate with the pressure feeding assembly 300, the rotating core 220 is provided with a third central hole 290 in communication with the temporary storage cavity, the third central hole 290 is located in the same rotating plane as the first central hole 270 and the second central hole 280, and the central axis of the third central hole 290 is perpendicular to the central axis of the first central hole 270.

[0095] When the rotating core 220 is rotated to the first central hole 270 in communication with the pressure feeding assembly 300, the third central hole 290 is in communication with the material mixing and spraying pipe 100, and the material directly enters the material mixing and spraying pipe 100 through the first central hole 270, the temporary storage cavity and the third central hole 290.
