Description

Technical Field

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

[0002] Saline-alkali land refers to soil with high salt or alkalinity content, which cannot be used to grow crops directly. In order to make full use of resources, it is necessary to improve saline-alkali land with high salt or alkalinity content. Improvement methods include water conservancy improvement, agricultural technology improvement, biological improvement and chemical improvement. Common agricultural technology improvements require spraying improvers on the land. For example, a Chinese patent with publication number: CN118556462A discloses a liquid improver uniformly spreading device for saline-alkali soil improvement. The device drives the frame as a whole to move in the field through a tractor, so that the soil hardness detection mechanism installed on the drum detects the soil hardness of each area of ​​the field. When the harder soil in the field is detected (harder soil means that the saline-alkali soil in this area has a higher salt content and more water loss, resulting in the soil here being drier and harder), the control component drives the support disk to rotate a certain angle, so that the impeller housing installed on the support disk can be deflected as a whole, reducing the transmission resistance between the driven wheel and the driving wheel, so that the driving wheel can drive the driven wheel to rotate faster, and increase the speed of the driven wheel driving the impeller to rotate through the transmission shaft, so that the impeller can faster send the improver solution in the water tank through the hose and the connecting pipe into the two spray pipes, thereby increasing the amount of improver sprayed by the spray pipe on the soil in this area, which is conducive to better improving the water retention of the soil here.

[0003] However, since the hard soil and soft soil in the soil are unevenly distributed, and the 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, the pressure rod will be lifted up when passing through the hard soil, which will cause the spraying amount of the spray pipe to increase on all the soil passed by the pressure rod, resulting in a waste of the spray amount of the amendment, and there are gaps between the pressure rods, so the pressure rod will cross part of the hard soil when rolling on the soil, greatly reducing the recognition efficiency of the hard soil. Summary of the invention

[0004] In order to overcome the problem that the spraying pipe increases the spraying volume for all the soil passed by the pressure rod, resulting in waste of the spraying volume of the improver, and there are intervals between the pressure rods, so that the pressure rods will cross over part of the hard soil when rolling on the soil, greatly reducing the recognition efficiency of the hard soil, the present invention provides a saline-alkali land soil improvement and treatment equipment.

[0015] 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.

[0016] 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.

[0017] 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.

[0023] A scraper 1013 is also included; each push rod 109 is fixedly connected to a scraper 1013, and the scraper 1013 is in contact with the corresponding pressure roller 103.

[0024] The scraper 1013 is arranged in an arc shape to limit the scraped soil, so that the soil falls downward along the surface of the corresponding pressure roller 103, thereby preventing the soil scraped by the scraper 1013 from being pushed to the surface of the adjacent pressure roller 103.

[0025] It also includes scrapers 1014; each scraper 1013 is fixedly connected to two scrapers 1014.

[0026] It also includes a water inlet pipe 1015 and a water delivery pipe 1016; the fixed frame 3 is fixedly connected with the water inlet pipe 1015; the water inlet pipe 1015 is connected with a plurality of water delivery pipes 1016, and the water delivery pipe 1016 is connected with the infusion pipe 105, and the water delivery pipe 1016 is located between two adjacent spacers 1051.

[0027] A sealing ring is provided between the push rod 109 and the infusion tube 105 to seal the contact portion between the push rod 109 and the infusion tube 105 , thereby preventing the liquid improver in the infusion tube 105 from leaking when the push rod 109 moves vertically in the infusion tube 105 .

[0028] When in use, the device is placed in the saline-alkali land to be improved, and the outlet of the liquid storage tank 4 is connected to the liquid inlet pipe 304 through an external hose, and the external water pump is connected to the water inlet pipe 1015. Then, the hydraulic cylinder 2 is controlled to drive the fixed frame 3 and the parts thereon to move downward until the pressure roller 103 sinks to a predetermined depth below the ground line 11, such as Figure 1 As shown, the vehicle body 1 is then controlled 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 Ⅰ102. At the same time, the pump in the liquid storage tank 4 is controlled to start, and the liquid improver in the liquid storage tank 4 is transported to the liquid inlet pipe 304 through the external hose. The improver enters the hollow tube 303 and the liquid inlet bucket 1011 through the liquid inlet pipe 304, and flows downward from the gap between the liquid inlet bucket 1011 and the plug 1012, flows into the area between the two adjacent partitions 1051 in the liquid delivery pipe 105, and then enters the area between the two adjacent partitions 1071 in the liquid spraying pipe 107 through the connecting pipe 106, and finally sprays downward from the circular pipe 108 to the soil surface, thereby improving the salinity and alkalinity of the soil.

[0029] When one or several rollers 103 pass through hard saline-alkali soil, the corresponding roller 103 is pushed up by the hard soil, the spring rod I 102 is compressed, and the elastic cloth 104 undergoes adaptive deformation to seal the inside of the roller 103 to prevent soil from entering the roller 103. The roller 103 pushes the push rod 109 upward, and the spring rod II 1010 is compressed, so that the push rod 109 drives the plug 1012 to move upward, so that the gap between the plug 1012 and the liquid inlet hopper 1011 increases, and then the flow rate of the liquid improver through the gap between the plug 1012 and the liquid inlet hopper 1011 increases, and then the amount of improver flowing downward from the liquid inlet hopper 1011 to the infusion pipe 105 increases, and finally the amount of improver sprayed into the soil from the circular tube 108 increases, so that the corresponding hard soil obtains more improver, while the soft soil in other areas maintains a normal spraying amount.

[0030] When the pressure roller 103 rolls on the soil surface, the soil will adhere to the surface of the pressure roller 103, which increases the thickness of the surface of the pressure roller 103, thereby causing the depth of the pressure roller 103 sunk into the soil to be inconsistent with the predetermined depth, so that the pressure roller 103 will be lifted up by the soil attached to the surface during the rolling process, causing an abnormal increase in the amount of liquid sprayed. Therefore, the pressure roller 103 contacts the scraper 1013 during rolling, and the scraper 1013 scrapes off the soil on the surface of the pressure roller 103 in time to clean the surface of the pressure roller 103.

[0031] When a pressure roller 103 rolls to a pit or a relatively soft area in the soil, the pressure roller 103 will fall downward under the elastic force of the spring rod Ⅰ102, and the top rod 109 and the scraper 1013 will also move downward under the elastic force of the spring rod Ⅱ1010, so that the pressure roller 103 maintains contact with the scraper 1013, and the telescopic end of the scraper 1013 can still scrape the soil on the surface of the pressure roller 103. At the same time, the top rod 109 drives the plug 1012 to move downward, thereby reducing the gap between the plug 1012 and the liquid inlet bucket 1011, thereby reducing the amount of liquid sprayed by the circular tube 108 into the pit or relatively soft area in the soil.

[0032] When one of the pressure rollers 103 is lifted up by the hard soil, the soil will adhere to the front and rear sides of the pressure roller 103 when the pressure roller 103 rolls on the soil surface, causing too much soil to be mixed between two adjacent pressure rollers 103, causing the pressure rollers 103 to be stuck and unable to rotate. Therefore, after one pressure roller 103 is lifted up by the hard soil, the scraper 1014 on the adjacent pressure roller 103 contacts the front and rear sides of the lifted pressure roller 103, thereby scraping off the soil adhered to the front and rear sides of the lifted pressure roller 103.

[0033] Since the right side of the pressing 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 pressing roller 103, if the pressing roller 103 is pushed up, the circular tube 108 will increase the spraying amount of the improver, and part of the improver sprayed by the circular tube 108 will be sprayed on the soft soil on the left side of the pressing roller 103, resulting in a waste of the improver. Therefore, a high-concentration improver liquid is transported to the liquid inlet pipe 304. When the high-concentration liquid enters the liquid inlet pipe 105 from the liquid inlet bucket 1011, the external water pump is controlled to transport clean water to the liquid inlet pipe 105 through the water inlet pipe 1015 and the water delivery pipe 1016. The clean water and the high-concentration liquid are mixed and sprayed from the circular tube 108 onto the soil through the connecting pipe 106 and the liquid spraying pipe 107. , and then improve the soil. After the pressure roller 103 is lifted up by the hard soil, the pressure roller 103 lifts the push rod 109 upward, and the push rod 109 drives the plug 1012 to move upward, thereby increasing the gap between the plug 1012 and the liquid inlet hopper 1011, thereby increasing the amount of liquid medicine entering the infusion pipe 105 from the liquid inlet hopper 1011, so that the concentration of the liquid medicine and water mixture in the infusion pipe 105 increases, and the high-concentration mixed liquid in the infusion pipe 105 requires the original low-concentration liquid medicine of the connecting pipe 106 and the spray pipe 107 to be sprayed out from the circular pipe 108, so that the high-concentration mixed liquid can be sprayed into the soil, thereby delaying the timing of the high-concentration mixed liquid being sprayed into the soil, so that the high-concentration mixed liquid sprayed from the circular pipe 108 can be sprayed into the hard soil.

[0034] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 and Figure 6 As shown, it also includes a fixed plate 301 and a lever 302; the fixed frame 3 is connected to the fixed plate 301; the fixed plate 301 is fixedly connected to a plurality of levers 302, and the levers 302 are located in front of the movement direction of the pressure roller 103, and the levers 302 are arranged in an eight-shaped shape.

[0035] It also includes a spring rod IV305, a baffle 306 and a connecting rod 307; the fixing frame 3 is slidably connected to the fixing plate 301; the vehicle body 1 is fixedly connected to two spring rods IV305; the telescopic ends of all spring rods IV305 are commonly fixedly connected to a baffle 306, and the baffle 306 is slidably connected to the hollow tube 303, and the upper side of the baffle 306 is in contact with the lower side of the liquid inlet pipe 304; the fixing plate 301 is fixedly connected to the connecting rod 307, and the connecting rod 307 is fixedly connected to the baffle 306.

[0036] 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.

[0037] 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.

[0038] Embodiment 3: Based on embodiment 2, Figure 4-Figure 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 .

[0039] 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.

[0040] 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.
