Description

Technical Field

[0001] The present invention relates to the field of soil improvement, and in particular to a device for improving saline-alkali soil treatment. Background Art

[0002] Saline-alkali soil refers to soil with a high salt or alkali content, which cannot be directly planted with crops. In order to make full use of resources, it is necessary to improve saline-alkali soil with a high salt and alkali content. Improvement methods include water conservancy improvement, agricultural technology improvement, biological improvement, and chemical improvement;

[0003] In common agricultural technology improvement, it is necessary to spray a modifier on the land. For example, a Chinese patent with the publication number: CN118556462A discloses a device for evenly spraying a liquid modifier for saline-alkali soil improvement. It drives the entire frame to move in the field by a tractor, so that the soil hardness detection mechanism installed on the roller detects the soil hardness of each area of the field. When detecting a relatively hard soil area in the field (relatively hard soil indicates that the salt content in the saline-alkali soil in this area is relatively high, and the water loss is relatively large, resulting in relatively dry and hard soil here), the control component drives the support disk to rotate a certain angle, so that the entire impeller housing installed on the support disk can deflect accordingly, reducing the transmission resistance between the driven wheel and the driving wheel, enabling the driving wheel to drive the driven wheel to rotate faster, increasing the rotation speed of the impeller driven by the driven wheel through the transmission shaft, enabling the impeller to more quickly send the modifier solution in the water tank into the two spraying pipes through the hose and the connecting pipe, thereby increasing the spraying amount of the modifier on the soil in this area, which is beneficial to better improving the water retention of the soil here.

[0004] However, since the hard soil and soft soil in the soil are unevenly distributed, and its pressure rod has a certain length, when the pressure rod passes through the soil, if the soil at one end of the pressure rod is hard saline-alkali soil and the soil at the other end of the pressure rod is normal soft soil, the pressure rod will be lifted when passing through the hard soil, which will cause the spraying pipe to increase the spraying amount for all the soil passed by the pressure rod, resulting in waste of the spraying amount of the modifier. Moreover, there is a gap between the pressure rods, and when the pressure rods roll on the soil, they will straddle some hard soil, greatly reducing the recognition efficiency of hard soil. Summary of the Invention

[0005] In order to overcome the shortcomings that the spraying pipe increases the spraying amount for all the soil passed by the pressure rod, resulting in waste of the spraying amount of the modifier, and there is a gap between the pressure rods, and when the pressure rods roll on the soil, they will straddle some hard soil, greatly reducing the recognition efficiency of hard soil, the present invention provides a device for improving saline-alkali soil treatment.

[0008] Further description, it further includes a scraping plate; each top rod is fixedly connected with a scraping plate, and the scraping plate is in contact with the corresponding pressing roller.

[0009] Further description, the scraping plate is arc-shaped.

[0010] Further description, it further includes scraping pieces; each scraping plate is fixedly connected with a plurality of scraping pieces.

[0011] Further description, it further includes a water inlet pipe and a water delivery pipe; the fixing frame is fixedly connected with the water inlet pipe; the water inlet pipe is communicated with a plurality of water delivery pipes, and the water delivery pipes are communicated with the infusion pipe, and the water delivery pipes are located between two adjacent partitions.

[0012] It is further explained that a sealing ring is provided between the push rod and the infusion tube.

[0013] Further description, it also includes a fixed plate and a shifting rod; the fixed frame is connected to the fixed plate; the fixed plate is fixedly connected to a plurality of shifting rods, and the shifting rods are located in front of the movement direction of the pressure roller.

[0014] Further description, it also includes a spring rod IV, a baffle and a connecting rod; the fixed frame is slidably connected to the fixed plate; a number of spring rods IV are fixedly connected to the vehicle body; the telescopic ends of all spring rods IV are commonly fixedly connected to a baffle, and the baffle is slidably connected to the hollow tube, and the upper side of the baffle is in contact with the lower side of the liquid inlet pipe; the fixed plate is fixedly connected to the connecting rod, and the connecting rod is fixedly connected to the baffle.

[0016] The beneficial effects of the present invention are as follows: when one or several of the pressure rollers of the present invention pass through hard saline-alkali soil, the corresponding pressure roller is pushed up by the hard soil, the spring rod I is compressed, and the elastic cloth undergoes adaptive deformation to seal the inside of the pressure roller to prevent soil from entering the inside of the pressure roller. The pressure roller pushes the push rod upward, and the spring rod II is compressed, so that the push rod drives the plug to move upward, so that the gap between the plug and the liquid inlet hopper increases, and then the flow rate of the liquid improver passing through the gap between the plug and the liquid inlet hopper increases, and then the amount of improver flowing downward from the liquid inlet hopper to the infusion pipe increases, and finally the amount of improver sprayed from the circular tube into the soil increases, so that the corresponding hard soil obtains more improver, while the soft soil in other areas maintains a normal spraying amount.

[0017] The present invention enables the pressure roller to contact with the scraper when rolling, and the scraper promptly scrapes off the dirt on the surface of the pressure roller to clean the surface of the pressure roller. When a pressure roller rolls to a pit or a relatively soft area in the soil, the pressure roller will fall downward under the elastic force of the spring rod I, and the push rod and the scraper will also move downward under the elastic force of the spring rod II, so that the pressure roller is separated from the contact with the scraper, and the telescopic end of the scraper can still scrape off the dirt on the surface of the pressure roller. At the same time, the push rod drives the plug to move downward, thereby reducing the gap between the plug and the liquid inlet hopper, thereby reducing the amount of liquid sprayed by the round tube into the pit or the relatively soft area in the soil.

[0018] When the lever of the present invention pushes the hard soil blocks and stones to the front and rear sides, the lever drives the fixed plate to slide leftward on the fixed frame under the action of the continuous rightward movement of the vehicle body, and the fixed plate drives the connecting rod and the baffle plate to move leftward, the spring rod IV is compressed, and then the baffle plate blocks a part of the pipe opening at the lower end of the liquid inlet pipe, thereby reducing the pipe opening at the lower end of the liquid inlet pipe, thereby reducing the amount of the modified liquid entering the hollow pipe from the liquid inlet pipe, and thereby reducing the amount of soil sprayed from the circular pipe.

[0028] It also includes a fixed shaft 101, a spring rod I 102, a pressure roller 103, an elastic cloth 104 and a liquid spraying assembly; the fixing frame 3 is rotatably connected with the fixed shaft 101; the fixed shaft 101 is connected with a number of rod groups linearly distributed along the axis of the fixed shaft 101; each rod group is composed of two vertically distributed spring rods I 102, and the fixed ends of the spring rods I 102 are fixedly connected with the fixed shaft 101; the telescopic ends of the two spring rods I 102 in the same rod group are each slidably connected with a pressure roller 103; each pressure roller 103 is provided with a chute 1031, and a slider is arranged corresponding to the telescopic end of the spring rod I 102, and the slider slides in the chute 1031; each pressure roller 103 is fixedly connected with two elastic cloths 104, and a rotating ring is fixedly connected to the middle of each elastic cloth 104, and all the rotating rings are jointly rotatably connected with the fixed shaft 101; the vehicle body 1 is connected with a liquid spraying assembly for spraying the liquid modifier.

[0029] The liquid spraying assembly includes an infusion pipe 105, a connecting pipe 106, a liquid spraying pipe 107, a round pipe 108, a top rod 109, a spring rod II 1010, a liquid inlet hopper 1011, a plug 1012, a hollow pipe 303 and a liquid inlet pipe 304; the vehicle body 1 is fixedly connected with the infusion pipe 105; a number of partitions 1051 are fixedly connected in the infusion pipe 105; the infusion pipe 105 is communicated with a number of connecting pipes 106, and the connecting pipes 106 are located between two adjacent partitions 1051, and the number of the connecting pipes 106 corresponds to the number of the pressure rollers 103; the vehicle body 1 is fixedly connected with the liquid spraying pipe 107; a number of partitions 1071 are fixedly connected in the liquid spraying pipe 107, and the liquid spraying pipe 107 is communicated with the connecting pipe 106, and the connecting pipe 106 is located between two adjacent partitions 1071; the liquid spraying pipe 107 is communicated with a number of round pipes 108, and the round pipes 108 are separated by the partitions 1071; a number of top rods 109 are slidably connected in the infusion pipe 105, and the number and positions of the top rods 109 correspond to those of the pressure rollers 103, and the top rods 109 are in contact with the upper sides of the corresponding pressure rollers 103; a number of spring rods II 1010 are fixedly connected to the infusion pipe 105, and the telescopic ends of the spring rods II 1010 are fixedly connected with the corresponding top rods 109; the infusion pipe 105 is communicated with a number of conical liquid inlet hoppers 1011, and the liquid inlet hoppers 1011 are located above the corresponding top rods 109; each top rod 109 is connected with a conical plug 1012, and the plug 1012 is located in the corresponding liquid inlet hopper 1011; the vehicle body 1 is fixedly connected with a hollow pipe 303, and the hollow pipe 303 is communicated with the liquid inlet hopper 1011; the hollow pipe 303 is communicated with a liquid inlet pipe 304.

[0030] It further includes a scraper 1013; each ejector rod 109 is fixedly connected with a scraper 1013, and the scraper 1013 is in contact with the corresponding pressure roller 103.

[0031] The scraper 1013 is arc-shaped to limit the scraped soil, so that the soil drops downward along the surface of the corresponding pressure roller 103, thereby preventing the soil scraped by the scraper 1013 from being pushed onto the surface of the adjacent pressure roller 103.

[0032] It further includes a scraping blade 1014; two scraping blades 1014 are fixedly connected to each scraper 1013.

[0033] It further includes a water inlet pipe 1015 and a water delivery pipe 1016; the fixing frame 3 is fixedly connected with the water inlet pipe 1015; the water inlet pipe 1015 is communicated with a plurality of water delivery pipes 1016, and the water delivery pipe 1016 is communicated with the infusion pipe 105, and the water delivery pipe 1016 is located between two adjacent partitions 1051.

[0034] A sealing ring is provided between the ejector rod 109 and the infusion pipe 105 to seal the contact part between the ejector rod 109 and the infusion pipe 105, thereby preventing the liquid conditioner in the infusion pipe 105 from leaking when the ejector rod 109 moves vertically in the infusion pipe 105.

[0035] During use, place this device in the saline-alkali land to be improved, connect the discharge port of the liquid storage tank 4 with the liquid inlet pipe 304 through an external hose, connect the external water pump with the water inlet pipe 1015, then, control the hydraulic cylinder 2 to drive the fixing frame 3 and the parts thereon to move downward until the pressure roller 103 sinks to a predetermined depth below the ground line 11, as Figure 1 shown. Subsequently, control the vehicle body 1 to drive the hydraulic cylinder 2, the fixing frame 3 and the parts thereon to move to the right. While the pressure roller 103 rolls on the soil surface, the pressure roller 103 rolls the soil downward under the elastic force of the spring rod Ⅰ 102. At the same time, control the pump in the liquid storage tank 4 to start, and convey the liquid conditioner in the liquid storage tank 4 to the liquid inlet pipe 304 through an external hose. The conditioner enters the hollow pipe 303 and the liquid inlet hopper 1011 through the liquid inlet pipe 304, and flows downward from the gap between the liquid inlet hopper 1011 and the plug 1012, and flows into the area between two adjacent partitions 1051 in the infusion pipe 105. Then, it enters the area between two adjacent partitions 1071 in the liquid spraying pipe 107 through the connecting pipe 106, and finally sprays downward from the round pipe 108 onto the soil surface, thereby improving the salinity of the soil.

[0036] When one or several of the pressure rollers 103 pass through hard saline-alkali soil, the corresponding pressure roller 103 is lifted upward by the hard soil, the spring rod I 102 is compressed, and the elastic cloth 104 undergoes an adaptive deformation to seal the inside of the pressure roller 103, preventing soil from entering the inside of the pressure roller 103. The pressure roller 103 pushes the ejector rod 109 upward, and the spring rod II 1010 is compressed, causing the ejector rod 109 to drive the plug 1012 to move upward, increasing the gap between the plug 1012 and the liquid inlet hopper 1011. As a result, the flow rate of the liquid conditioner passing through the gap between the plug 1012 and the liquid inlet hopper 1011 increases, and thus the amount of the conditioner flowing downward from the liquid inlet hopper 1011 into the infusion tube 105 increases. Eventually, the amount of the conditioner sprayed from the round tube 108 into the soil increases, so that the corresponding hard soil obtains more conditioner, while the soft soil in other areas maintains the normal spraying amount.

[0037] When the pressure roller 103 rolls on the soil ground, soil will adhere to the surface of the pressure roller 103, increasing the thickness of the surface of the pressure roller 103. As a result, the depth at which the pressure roller 103 sinks into the soil is inconsistent with the predetermined depth, causing the pressure roller 103 to be lifted upward by the soil adhered to its surface during the rolling process, resulting in an abnormal increase in the liquid spraying amount. Therefore, when the pressure roller 103 rolls, it contacts the scraper 1013, and the scraper 1013 scrapes off the soil on the surface of the pressure roller 103 in a timely manner to clean the surface of the pressure roller 103.

[0038] When a pressure roller 103 rolls into a pit or a relatively soft area in the soil, the pressure roller 103 will drop downward under the elastic force of the spring rod I 102, and the ejector rod 109 and the scraper 1013 will also move downward under the elastic force of the spring rod II 1010, keeping the pressure roller 103 in contact with the scraper 1013. The telescopic end of the scraper 1013 can still scrape off the soil on the surface of the pressure roller 103. At the same time, the ejector rod 109 drives the plug 1012 to move downward, reducing the gap between the plug 1012 and the liquid inlet hopper 1011, thereby reducing the liquid spraying amount into the pit or the relatively soft area in the soil from the round tube 108.

[0039] When one of the pressure rollers 103 is lifted upward by the hard soil, when the pressure roller 103 rolls on the soil surface, soil will adhere to the front and rear sides of the pressure roller 103, causing too much soil to be trapped between two adjacent pressure rollers 103, resulting in the situation where the pressure roller 103 is stuck and cannot rotate. Therefore, after one of the pressure rollers 103 is lifted by the hard soil, the scraping blades 1014 on the adjacent pressure rollers 103 contact the front and rear sides of the lifted pressure roller 103, and then scrape off the soil adhered to the front and rear sides of the lifted pressure roller 103.

[0040] Since the right side of the pressure roller 103 contacts the hard soil first, and there is still a certain distance between the circular tube 108 and the right side of the pressure roller 103. If the spraying amount of the modifier is increased in the circular tube 108 as soon as the pressure roller 103 is jacked up, a part of the modifier sprayed from the circular tube 108 will be sprayed on the soft soil on the left side of the pressure roller 103, resulting in waste of the modifier. Therefore, the high-concentration modifier liquid medicine is conveyed into the liquid inlet pipe 304. When the high-concentration liquid medicine enters the infusion pipe 105 from the liquid inlet hopper 1011, an external water pump is controlled to convey clear water into the infusion pipe 105 through the water inlet pipe 1015 and the water delivery pipe 1016. After the clear water and the high-concentration liquid medicine are mixed, they are sprayed onto the soil from the circular tube 108 through the connecting pipe 106 and the liquid spraying pipe 107, thereby improving the soil. After the pressure roller 103 is jacked up by the hard soil, the pressure roller 103 jacks up the ejector rod 109, and the ejector rod 109 drives the plug 1012 to move upward, thereby increasing the gap between the plug 1012 and the liquid inlet hopper 1011, so as to increase the amount of the liquid medicine entering the infusion pipe 105 from the liquid inlet hopper 1011, making the concentration of the liquid medicine and clear water mixture in the infusion pipe 105 increase. The high-concentration mixture in the infusion pipe 105 needs to spray the original low-concentration liquid medicine in the connecting pipe 106 and the liquid spraying pipe 107 from the circular tube 108 in order to spray the high-concentration mixture onto the soil, thereby delaying the timing of the high-concentration mixture being sprayed onto the soil and making the high-concentration mixture sprayed from the circular tube 108 spray into the hard soil.

[0041] Example 2: On the basis of Example 1, as Figure 2 、 Figure 3 and Figure 6 shown, it further includes a fixing plate 301 and a lever 302; the fixing frame 3 is connected with the fixing plate 301; the fixing plate 301 is fixedly connected with a plurality of levers 302, and the levers 302 are located in front of the moving direction of the pressure roller 103, and the levers 302 are arranged in a shape of an eight.

[0042] It further includes a spring rod Ⅳ 305, a baffle 306 and a connecting rod 307; the fixing frame 3 is slidably connected with the fixing plate 301; the vehicle body 1 is fixedly connected with two spring rods Ⅳ 305; the telescopic ends of all the spring rods Ⅳ 305 are commonly fixedly connected with a baffle 306, and the baffle 306 is slidably connected with the hollow tube 303, and the upper side of the baffle 306 contacts the lower side of the liquid inlet pipe 304; the fixing plate 301 is fixedly connected with a connecting rod 307, and the connecting rod 307 is fixedly connected with the baffle 306.

[0043] There may be large hard lumps of soil or gravel on the soil surface, which may cause the pressure roller 103 to be pushed upward when passing through the hard lumps of soil or gravel, resulting in an abnormal increase in the spraying amount of the circular tube 108. Therefore, an eight-shaped lever 302 is arranged in front of the movement direction of the pressure roller 103, so that when the lever 302 passes through the soil surface, the hard lumps of soil and gravel on the soil surface are pushed away to the front and rear sides, thereby reducing the impact of the hard lumps of soil and gravel on the pressure roller 103.

[0044] When the lever 302 pushes the hard soil and stones to the front and rear sides, the resistance to the lever 302 will increase, thereby causing the resistance to the rightward movement of the vehicle body 1 to increase and the speed of rightward movement to decrease. At this time, if the spraying amount of the circular tube 108 remains unchanged at the normal spraying amount, the modified amount of local soil spraying will increase. Therefore, when the lever 302 pushes the hard soil and stones to the front and rear sides, the lever 302 drives the fixed plate 301 to slide left on the fixed frame 3 under the action of the continuous rightward movement of the vehicle body 1, and the fixed plate 301 drives the connecting rod 307 and the baffle 306 to move left, and the spring rod IV 305 is compressed, so that the baffle 306 blocks a part of the pipe opening at the lower end of the liquid inlet pipe 304, thereby reducing the pipe opening at the lower end of the liquid inlet pipe 304, thereby reducing the modified amount entering the hollow tube 303 from the liquid inlet pipe 304, and thereby reducing the amount of soil sprayed from the circular tube 108.

[0045] Embodiment 3: Based on embodiment 2, Figures 4 - 5 As shown, it also includes a protruding rod 308 ; each scraper 1013 is provided with a notch 13 ; each pressure roller 103 is fixedly connected with a plurality of annularly distributed protruding rods 308 , and the protruding rods 308 pass through the notch 13 .

[0046] When the pressure roller 103 rolls on the soil, it drives the convex rod 308 to rotate, thereby increasing the friction between the pressure roller 103 and the soil through the convex rod 308. The convex rod 308 passes through the groove 13 when following the pressure roller 103 to rotate, and because the lever 302 has already pushed away the large rocks and hard soil blocks, even if there are small stones in the soil, they will be crushed by the convex rod 308, so the broken small stones will not push the convex rod 308 and the pressure roller 103 upwards.

[0047] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
