Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a deep tillage machine. Background Art

[0002] A subsoiler is an agricultural machine used for deep loosening and tidying of land to improve soil structure, increase soil fertility, and thus promote the growth of crops. Existing vibrating subsoilers, vibrating subsoilers are chisel shovels, and the technical principle is to loosen deep soil strips locally, with the purpose of breaking the bottom layer of the plow. Existing wing shovel subsoilers: The working part of this subsoiler is a series of wing-shaped shovels, which can flip and move a large amount of soil, thereby achieving rapid and large-scale soil loosening, which seriously damages the soil structure. Existing chisel subsoilers: Also known as single-column subsoilers, its working part is a shovel column with a blade, which is used to loosen the entire layer of soil at intervals. This subsoiler is suitable for relatively hard soils. The shovel column can be inserted into the deep soil layer to break the soil compaction and improve the permeability and air permeability of the soil. Its disadvantages are large traction requirements and limited soil loosening range: Although the chisel subsoiler can loosen the deep layer, its range of action is relatively limited and may not cover all areas that need to be loosened, especially when the soil is severely compacted. Traditional deep tillage machines mainly use mechanical methods to deep till the soil. Pure mechanical deep tillage cannot achieve a good uniform loosening effect in the deep soil, and has a poor loosening effect on the deep soil, which limits the deep growth of crop roots.

[0003] In order to solve the above problems, the present invention provides a deep tillage machine, which realizes deep loosening and ventilation of the soil through the combined use of a front deep tillage plow, an air compressor and a liquefied gas tank. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment one:

[0039] See also Figure 1-7As shown, the present invention is a deep tillage machine, and its structure includes a front deep tillage plow 1, an equipment vehicle 2, a rear deep tillage plow 3, an air compressor 4, and a liquefied gas tank 5. The front deep tillage plow 1, the equipment vehicle 2, and the rear deep tillage plow 3 are hinged in sequence from front to back. The air compressor 4 and the liquefied gas tank 5 are respectively installed on the equipment vehicle 2. The front deep tillage plow 1 is used to deep till the soil when the tractor pulls things; the air compressor 4, the liquefied gas tank 5, and the front deep tillage plow 1 are combined to mix the combustible gas and air and rush them into the ground. When ignited, they are detonated under the front deep tillage plow 1 and the equipment vehicle 2 to blast the soil deeply, and the high pressure generated at the moment of the explosion is used to loosen the soil; the rear deep tillage plow 3 cooperates with the air compressor 4 to encrypt and loosen the soil layer after the blasting, and introduces air to discharge the carbon dioxide and heat generated by the blasting. The deep soil is loosened and in an oxygen-rich state, which can increase the microbial activity of the soil, which is conducive to the decomposition of organic matter by deep soil microorganisms, thereby increasing the intensity of soil respiration, which helps to increase the fertility of the soil.

[0040] The structure of the front deep tillage plow 1 specifically includes a front plow frame 11 and three deep tillage shovels 12. The deep tillage shovels 12 vertically penetrate the front plow frame 11 and are fixed on the front plow frame 11 by two first latches 13. The three deep tillage shovels 12 are arranged in a triangle. The deep tillage shovel 12 includes a rectangular plow column 121, an inclined plow column 122 and a loosening knife 123 connected as a whole from top to bottom. A limiting plate 124 is fixed to the upper end of the rectangular plow column 121, which is located in the front half of the deep tillage direction of the deep tillage shovel 12. The upper end of the rectangular plow column 121, which is located in the rear half of the deep tillage direction of the deep tillage shovel 12, is provided with a mixing air guide hole 125 arranged along the length direction of the rectangular plow column 121. The mixing air guide hole 125 passes through the rectangular plow column 121 and the inclined plow column 122. A first internally threaded blind hole 126 and a second internally threaded blind hole 127 connected to the mixed air guide hole 125 are provided on the rear wall of the upper end of the rectangular plow column 121, and the first internally threaded blind hole 126 is located on the upper side of the second internally threaded blind hole 127. A row of vertically arranged first positioning pin holes 129 are provided on the upper half of the side surface of the rectangular plow column 121. The first latch 13 is inserted into the first positioning pin holes 129 at different height positions to adjust the specific deep tillage depth of the deep tillage shovel 12. An air outlet channel 128 connected to the mixed air guide hole 125 is provided on the rear wall of the lower end of the rectangular plow column 121. A first air pipe joint is installed at the upper end of the mixed air guide hole 125. A second air pipe joint is installed on the first internally threaded blind hole 126. A timing igniter 6 is installed on the second internally threaded blind hole 127. The timing igniter 6 includes three ignition needles, a pulse igniter, a timing module assembly, a power board assembly and a power supply. The three ignition needles are respectively installed on the second internal threaded blind holes 127 on the three deep tillage shovels 12, and the pulse igniter, the timing module assembly, the power board assembly and the power supply are installed on the first horizontal carrier 111. The power board assembly is connected to the power supply. The pulse igniter and the timing module assembly are respectively connected to the power board assembly. The three ignition needles are connected to three of the pulse output connectors on the pulse igniter. The working mode of the timing module assembly is power-on delay / cycle delay. The pulse igniter is excited once at a set time interval, and the three ignition needles are ignited synchronously to provide a stable frequency of detonation ignition for deep tillage operations.

[0041] The air compressor 4 is powered by a diesel engine or a gasoline engine, which is convenient for field operations. Two air outlet pipes 41 are installed on the gas tank of the air compressor 4, and a first pressure reducing valve 42 and a ball valve 43 are installed on the two air outlet pipes 41 respectively. One of the air outlet pipes 41 is connected in parallel with the three first air pipe joints through a plurality of first air guide pipes and three-way joints. The ball valve 43 is opened during deep plowing operations, and the air compressor 4 simultaneously provides air to the three deep plowing shovels 12. The liquefied gas tank 5 is filled with propane or butane, and a second pressure reducing valve 51 is installed at the air outlet of the liquefied gas tank 5. The second pressure reducing valve 51 is connected in parallel with the three second air pipe joints through a plurality of second air guide pipes and three-way joints. The liquefied gas tank 5 provides combustible gas to the three deep plowing shovels 12 synchronously. The timing igniter 6 is set according to the speed of the tractor and the length of the equipment vehicle 2 to ignite once for each length of the equipment vehicle 2 traveled. The gaps created by the deep tillage shovel 12 when loosening the deep soil layer are completely filled with a mixture of air and combustible gas. After the timing igniter 6 is ignited, the flame is transmitted downward from the mixed gas guide hole 125, igniting the underground combustible gas to produce an instantaneous deflagration, and the generated gas blasts the deep soil as a whole into a soft and loose state. Compared with the simple deep tillage shovel 12 deep loosening, the present invention uses the deep tillage shovel 12 to loosen the soil and then rush in a mixture of air and combustible gas and ignite it, producing an explosion in the deep soil layer. The short-term airflow and shock wave blast the deep soil as a whole into a soft and loose state, greatly improving the overall deep loosening effect.

[0042] Among them, the front plow frame 11 includes a first horizontal platform 111. A four-rod fixing frame 112 whose upper ends converge at one point is fixed on the upper surface of the first horizontal platform 111. A first pin connection seat 113 connected to the traction device is fixed on the top of the four-rod fixing frame 112. A pair of fixed shaft pin seats 114 connected to the traction device are fixed on the first horizontal platform 111. Three first rectangular guide holes 115 that match the deep tillage shovel 12 are provided on the first horizontal platform 111. A first rectangular guide tube 116 that corresponds to the three first rectangular guide holes 115 is fixed on the upper surface of the first horizontal platform 111. Two first positioning sockets 117 that match the first latch 13 are provided on the first rectangular guide tube 116.

[0043] In order to prevent the flame from going backward upward when the timing igniter 6 ignites the combustible gas in the mixed gas guide hole 125, two layers of parallel steel mesh are fixed on the inner wall of the mixed gas guide hole 125, and the two layers of steel mesh are located between the first internal thread blind hole 126 and the second internal thread blind hole 127. The steel mesh effectively cools the flame and blocks the upward transmission. The re-injected air cools the steel mesh again, effectively ensuring the long-term stable operation of the overall ignition process.

[0044] The equipment vehicle 2 includes a bearing platform 21, a retractable wheel frame 22 and a first hydraulic cylinder 23. The lower surface of the bearing platform 21 is rotatably connected to the retractable wheel frame 22 through two seat bearings 24. The fixed end of the first hydraulic cylinder 23 is hinged to the bearing platform 21 through a hinge seat. The telescopic end of the first hydraulic cylinder 23 is rotatably connected to the retractable wheel frame 22. A guardrail frame 25 for placing a liquefied gas tank 5 is fixed on the upper surface of the bearing platform 21. The structure of the retractable wheel frame 22 specifically includes two parallel support frame rods 221. Step shafts 222 connected and matched with the seat bearings 24 are symmetrically fixed on the two support frame rods 221. A wheel 223 is installed at the lower end of each of the two support frame rods 221. A round rod 224 is fixed to the upper end of the two support frame rods 221 relative to the inner wall. The telescopic end of the first hydraulic cylinder 23 is sleeved on the round rod 224.

[0045] The bearing platform 21 of the equipment vehicle 2 is mainly used to carry the air compressor 4 and the liquefied gas tank 5. Secondly, the bearing platform 21 is also used to cover and suppress the soil that rises during blasting of deep soil, so as to avoid soil splashing during blasting and loosening. The first hydraulic cylinder 23 is used to control the retraction and extension of the retractable wheel frame 22. During deep plowing operations, the first hydraulic cylinder 23 is retracted, and the two wheels 223 are lifted upward and away from the ground; when plowing is finished, the first hydraulic cylinder 23 is extended, and the two wheels 223 move downward, lifting the entire bearing platform 21, and at the same time driving the rear deep plow 3 to rise and leave the land, and the tractor and the equipment vehicle 2 work together to lift the front plow frame 11 off the ground.

[0046] The guardrail frame 25 structure includes a circular cylinder 251 fixed on the upper surface of the bearing platform 21. Three columns 252 are fixed to half of the outer annular surface of the circular cylinder 251. A row of fixed clamps 253 are fixed to the three columns 252. The fixed clamps 253 are fixed with movable clamps 254 by bolt connection. The bottom of the liquefied gas tank 5 is placed in the circular cylinder 251, and then the movable clamp 254 is connected to the fixed clamp 253, and the liquefied gas tank 5 is clamped and fixed by bolts.

[0047] Among them, the rear deep tilling plow 3 includes a rear plow frame 31, a deep tilling hook 32 and a second hydraulic cylinder 33. The fixed end of the second hydraulic cylinder 33 is hinged to the carrier 21 through a hinge seat. The rear plow frame 31 includes a second horizontal carrier 311. A rectangular column 312 is fixed to the middle of one end of the upper surface of the second horizontal carrier 311. A diagonal tie rod 313 is fixed between the rectangular column 312 and the second horizontal carrier 311. A second pin connection seat 314 is fixed to the upper end of the rectangular column 312. The telescopic end of the second hydraulic cylinder 33 is connected to the second pin connection seat 314 through a latch. Five second rectangular guide holes 315 arranged in a V shape are provided on the surface of the second horizontal carrier 311. Five second rectangular guide tubes 316 respectively matched with the five second rectangular guide holes 315 are fixed on the surface of the second horizontal carrier 311. Two second positioning sockets 317 are provided on the second rectangular guide tube 316. The upper end of the deep loosening hook 32 passes through the second rectangular guide tube 316 and the second positioning plug hole 317 , and is connected and positioned by the second latch 34 .

[0048] The deep loosening hook 32 includes a rectangular upright handle portion 321 and a curved hook portion 322 integrally formed from top to bottom. A through air supplement guide hole 323 is provided at the upper end of the deep loosening hook 32 near the rear wall. A diversion air guide groove 324 connected to the air supplement guide hole 323 is provided on the rear wall of the lower end of the rectangular upright handle portion 321. A row of second positioning pin holes 325 arranged along its length direction are provided on the side wall of the upper half of the rectangular upright handle portion 321. A blade portion 326 is provided in the middle and lower half of the rectangular upright handle portion 321. A third air pipe joint is installed at the upper end of the air supplement guide hole 323. Another air outlet pipe 41 is connected in parallel with the three third air pipe joints through a plurality of third air guide pipes and three-way joints.

[0049] The deep loosening hook 32 installed on the rear deep loosening plow 3, which has a density greater than that of the deep tillage shovel 12, performs secondary deep loosening on the deep soil. By cooperating with the air compressor 4, air is introduced into the deep loosening hook 32, and fresh air is introduced into the deep soil that has been deeply loosened. A large amount of air is filled to the bottom of the deep soil, and the carbon dioxide produced by the explosion is discharged upward. The introduction of air can provide more oxygen, thereby promoting the activity of microorganisms and accelerating the decomposition of organic matter and the nutrient cycle. By introducing air into the deep soil, the redox potential of the soil can be increased, and the living space of pathogens can be reduced, which helps to control soil-borne diseases. For contaminated soil, promoting the degradation and removal of volatile organic pollutants by forced ventilation is an effective soil remediation technology. The introduction of air into the deep soil is of great significance for maintaining soil health, promoting plant growth, and improving soil remediation efficiency. Specific embodiment 2:

[0051] Based on the specific embodiment 1, the difference of this embodiment is that:

[0052] like Figure 8-10As shown, in order to level the land after deep tillage, a leveling roller 7 is hingedly installed at the tail of the rear deep tillage plow 3. The leveling roller 7 includes a U-shaped frame 71 and a pressure roller 72. The U-shaped frame 71 is rotatably connected to the pressure roller 72 through a bearing. Two fixed connecting rods 73 that are connected to the hinge seat through a pin are fixed to the outer wall of the U-shaped frame 71. The pressure roller 72 includes a round shaft rod 721. Two round plates 722 are fixed on the round shaft rod 721. A circle of cylindrical pressure rods 723 are fixed in a circular arrangement between the two round plates 722 relative to the inner wall. The leveling roller 7 levels the raised soil during the movement. Specific embodiment three:

[0054] Based on the specific embodiment 1, the difference of this embodiment is that:

[0055] like Fig.11 As shown, when the front deep tillage plow 1 is deep tilling, the rear resistance needs to be reduced when the tractor slips, in order to facilitate the release of the friction between the three deep tillage shovels 12 and the deep layer of the soil. The front deep tillage plow 1 also includes three third hydraulic cylinders 14. The lower end of the third hydraulic cylinder 14 is hinged to the upper surface of the first horizontal platform 111 through a hinge seat. The telescopic end of the third hydraulic cylinder 14 is hinged to the limit plate 124 through a hinge seat. The contraction length of the third hydraulic cylinder 14 matches the depth of the soil layer that needs to be deep tilled.
