DETAILED DESCRIPTION

[0028] The following will be combined with specific embodiments and attached Figure 1-11 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0029] A desert / salt-alkali land deep soil improvement device (such as Figure 1As shown), it includes a traction power mechanism 1, a hook-shaped hollow mechanical arm 2, a deep digging plow 3, a film roll 4, a biological bacteria spreading mechanism, a nutrient spreading mechanism, a film detection mechanism, and a controller. The traction power mechanism 1 can realize the traction movement of the hook-shaped hollow mechanical arm 2. The traction power mechanism 1 can be a bulldozer or a crawler chassis with a power drive mechanism. The hook-shaped hollow mechanical arm 2 can be swung up and down relative to the traction power mechanism 1 to adjust the positioning. The middle part of the hook-shaped hollow mechanical arm 2 is in a front-to-back through state. The deep digging plow 3 is arranged at the hook head end of the hook-shaped hollow mechanical arm 2. In actual application By adjusting the placement angle of the hook-shaped hollow mechanical arm 2, the depth to which the deep digging plough 3 finally extends into the soil can be achieved, thereby achieving flexible adjustment of the soil improvement depth. In order to facilitate the smooth movement of the deep digging plough 3 in the soil, the bottom of the deep digging plough 3 can be kept in a horizontal state. When the deep digging plough 3 extends to a certain depth in the soil, the middle and lower parts of the hook-shaped hollow mechanical arm 2 are all located in the soil. Since the interior of the hook-shaped hollow mechanical arm 2 is in a front-to-back through-state, the soil can smoothly pass through its internal cavity during the movement of the hook-shaped hollow mechanical arm 2 along the front-to-back direction, thereby greatly reducing the risk of the hook-shaped hollow mechanical arm 2 from moving too far. The moving resistance of the mechanical arm 2 is reduced. When the moving resistance is reduced, the power of the traction power mechanism 1 can be appropriately reduced, which is convenient for reducing the manufacturing cost. The deep digging plow 3 and the middle and lower parts of the hook-shaped hollow mechanical arm 2 synchronously realize the loosening function during the soil walking process; the film roll 4 is rotatably arranged inside the deep digging plow 3, and a film outlet 101 is arranged on the lower rear side of the deep digging plow 3. The deep digging plow 3 can drive the film roll 4 to move synchronously in the deep soil. The free end of the film roll 4 can be covered by the soil after being led out of the deep digging plow 3 through the film outlet 101, thereby realizing its fixation. After the free end of the film roll 4 is fixed During the movement of the film roll 4, the film roll 4 is gradually unfolded, and then the film 42 is deeply buried in the soil. The waterproof ability of the film 42 can effectively block the downward penetration of water, realize the deep soil water locking function, and thus help to save water resources; at the same time, the film 42 can effectively block the upward transmission of saline-alkali components in the deep desert / saline-alkali geology, and provide a guarantee for changing the composition of the upper geological layer; the biological bacteria sowing mechanism can sow biological bacteria to the upper left side of the film roll 4, and the nutrient sowing mechanism can sow nutrients to the upper left side of the film roll 4, When the deep digging plow 3 moves in the deep soil layer, the biological bacteria spreading mechanism and the nutrient spreading mechanism carry out the spreading work simultaneously, thereby realizing the spreading of nutrients and biological bacteria in the deep soil layer. The sown biological bacteria can reproduce from the deep soil and act on the roots of plants or the root system of crops and debris left after harvesting, thereby fundamentally changing the soil structure and nutrient components of the deep desert / salt-alkali strata; the sown nutrients, such as nitrogen, phosphorus, potassium and other nutrient elements, can change the soil nutrient conditions in a short period of time, thereby improving the survival rate of plants in desert / salt-alkali land;The film detection mechanism is used to detect whether the film 42 is broken or not. During the laying of the film 42, according to the detection result of the film detection mechanism on the film 42, the effective continuous laying of the film 42 in the deep soil layer can be ensured, and then the laying quality of the film 42 can be guaranteed. The controller can control the operation of the biological bacteria spreading mechanism, the nutrient spreading mechanism and the film detection mechanism. In the actual application process, the utility model can be used to realize the functions of loosening soil, laying film, spreading bacteria, and spreading nutrients at one time, thereby efficiently realizing soil improvement. ;

[0030] The applicant and relevant agricultural universities, combined with field investigations in Xinjiang, Inner Mongolia, etc., found that the deepest root depth of crops is about 1 meter. In order to facilitate the adjustment of the deep digging depth of the deep plow 3, the hook-shaped hollow mechanical arm 2 is enabled to move up and down relative to the traction power mechanism 1 for adjustment and positioning. By adjusting the high position of the hook-shaped hollow mechanical arm 2 on the traction power mechanism 1, the deep digging depth adjustment of the deep plow 3 is ultimately achieved. Therefore, in actual application, the film laying depth, nutrient and biological bacteria spreading depth can be adjusted according to the actual root depth of crops.

[0031] On the basis of the above embodiments, the specific implementation of the biological bacteria spreading mechanism is as follows: the biological bacteria spreading mechanism includes a biological bacteria storage box 51, a first pneumatic conveying mechanism, and a biological bacteria conveying pipeline 52. The feed end of the first pneumatic conveying mechanism is connected to the biological bacteria storage box 51, and the discharge end of the first pneumatic conveying mechanism is connected to the feed port of the biological bacteria conveying pipeline 52. The biological bacteria conveying pipeline 52 is used to direct the biological bacteria to the upper left side of the film roll 4; the controller can control the operation of the first pneumatic conveying mechanism. The first pneumatic conveying mechanism is a commonly used actuator in the field of pneumatic conveying materials. When it is running, it can use flowing air to realize the movement and transportation of materials. In this specific embodiment, the specific structure of the first pneumatic conveying mechanism is no longer described in detail; during the movement of the deep digging plow 3, the first pneumatic conveying mechanism works synchronously, so that the biological bacteria in the biological bacteria storage box 51 are continuously spread to the top of the film 42 through the diversion effect of the biological bacteria conveying pipeline 52.

[0032] On the basis of the above embodiment, the specific implementation method of the nutrient spreading mechanism is as follows: the nutrient spreading mechanism includes a nutrient storage box 61, a second pneumatic conveying mechanism, and a nutrient conveying pipe 62, the feed end of the second pneumatic conveying mechanism is connected to the nutrient storage box 61, the discharge end of the second pneumatic conveying mechanism is connected to the feed port of the nutrient conveying pipe 62, and the nutrient conveying pipe 62 is used to direct the nutrients to the upper left side of the film roll 4, and the controller can control the operation of the second pneumatic conveying mechanism. The second pneumatic conveying mechanism is a commonly used actuator in the field of pneumatic conveying materials. When it is running, it can use flowing air to realize the movement and transportation of materials. In this specific embodiment, the specific structure of the second pneumatic conveying mechanism is no longer described in detail; during the movement of the deep digging plow 3, the second pneumatic conveying mechanism works synchronously, so that the nutrients in the nutrient storage box 61 are continuously spread to the top of the film 42 through the diversion effect of the nutrient conveying pipe 62.

[0033] During the laying process of the film 42, due to the limitation of the total length of the film 42 in the film roll 4 or the film 42 may break at the film roll 4 during the laying process, the continuous laying of the film 42 will be interrupted. In order to realize the continuous and uninterrupted laying of the film 42 in the deep soil, the specific implementation method of the film detection mechanism is as follows: the film detection mechanism includes a film detection laser photoelectric switch 71 and a line through-pipe 72. The film detection laser photoelectric switch 71 is fixedly arranged on the lower left side of the film roll 4, and the film detection laser photoelectric switch 71 is used to detect the tensioned film 42 passing through the film outlet 101. The line through-pipe 72 is connected with the inside of the deep digging plow 3. The line 73 for realizing the electrical connection between the film detection laser photoelectric switch 71 and the controller passes through the line through-pipe 72. The line through-pipe 72 is used to realize the protection of the line 73. In actual application, when the film 42 on the film roll 4 is completely used up or the film 42 is broken at the film roll 4, there will be no tensioned film 42 at the film outlet 101. At this time, the laser photoelectric switch 71 transmits the detection signal to the controller, and the controller processes the signal. Then, an alarm message can be generated through the alarm device, so that after receiving the alarm message, the staff will check the corresponding situation. If the film 42 is used up, the film roll 4 will be replaced. If the film 42 is broken, the film 42 will be pulled out from the film outlet 101 again, and then the subsequent film laying operation will be carried out.

At the same time, the free rotation of the film roll 4 in the plowshare body 32 is guaranteed. In order to facilitate the film roll 4 to rotate in the plowshare body 32 The first rotating shaft 41 is provided with a detachable limit plate on the vertical clamping plate 322. The limit plate blocks the first rotating shaft 41, thereby limiting the movement of the first rotating shaft 41.
