A saline-alkali land ecological restoration device

Abstract

This invention relates to the field of saline-alkali land ecological restoration, and more particularly to a saline-alkali land ecological restoration device. Current saline-alkali land ecological restoration devices struggle to synchronize soil loosening and pesticide application, and often cause accumulated carbonates on the surface of the saline-alkali land to be re-entered into the soil. The saline-alkali land ecological restoration device includes a frame; four hydraulic push rods are fixedly connected to the frame, with two hydraulic push rods forming a group, and a mounting plate fixedly connected between the bottom of the telescopic rods of the two hydraulic push rods in the same group. The device loosens the saline-alkali land using a soil loosening paddle, and simultaneously administers restoration agents through a reagent tank, ensuring more thorough contact between the soil and the restoration agents, thereby neutralizing and restoring the saline-alkali soil. Simultaneously, several scrapers remove carbonates from the surface of the saline-alkali land, which are collected through a feed pipe, thus achieving simultaneous soil loosening and pesticide application, improving the restoration efficiency of the saline-alkali land.

Description

Technical Field

[0001] This invention relates to the field of saline-alkali land ecological restoration, and more particularly to a saline-alkali land ecological restoration device. Background Technology

[0002] Saline-alkali land is a type of salt accumulation, referring to soil where the salt content affects the normal growth of crops. Its formation is essentially due to the horizontal and vertical redistribution of various soluble salts on the ground, causing them to accumulate in the surface layer of the soil through capillary water transport. Through proper ecological restoration of saline-alkali land, a large amount of arable land resources can be obtained, breaking through the "ceiling" of increasing grain planting area and achieving the expansion, improvement, and efficiency of arable land resources.

[0003] However, most current saline-alkali land ecological restoration devices involve deep tilling of the saline-alkali land first, followed by chemical spraying for restoration. This process is complex and makes it difficult to synchronize soil loosening and chemical application, consuming a lot of manpower and time, resulting in low restoration efficiency. Furthermore, direct deep tilling of saline-alkali land can cause the carbonates accumulated on the surface of the saline-alkali land to be stirred back into the soil, thus resulting in poor restoration effects. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides an ecological restoration device for saline-alkali land, which can realize the synchronization of soil loosening and chemical application in saline-alkali land, improve the restoration efficiency of saline-alkali land, and more thoroughly scrape off the carbonates on the surface of saline-alkali land, so as to achieve better restoration effect.

[0005] An ecological restoration device for saline-alkali land includes a frame on which four hydraulic push rods are fixedly connected. Two hydraulic push rods form a group, and a mounting plate is fixedly connected between the bottom of the telescopic rods of two hydraulic push rods in the same group. The two mounting plates are symmetrically arranged, and a support frame is fixedly connected between the top of the two mounting plates. A chemical tank is fixedly connected to the support frame. One of the mounting plates is equipped with a soil turning component, and the soil turning component is equipped with a saline-alkali soil collection component, which is connected to the support frame.

[0006] Furthermore, the frame is equipped with four wheels at its bottom.

[0007] Furthermore, the bottom of the medicine tank has a discharge port, and a baffle is slidably connected to the discharge port at the bottom of the medicine tank.

[0008] Furthermore, the soil turning assembly includes a servo motor, with one of the mounting plates fixedly connected to the side away from the reagent tank. The output shaft of the servo motor passes through one of the mounting plates, and a pulley is fixedly connected to the output shaft of the servo motor. A soil loosening paddle is rotatably connected between the two mounting plates, and a drive wheel is provided on the soil loosening paddle. A drive belt is fitted between the pulley and the drive wheel of the soil loosening paddle.

[0009] Furthermore, the saline-alkali soil collection assembly includes a guide wheel, one end of which is fixedly connected to the guide wheel. The guide wheel has a corrugated guide groove. A movable rod is slidably connected between the two mounting plates. A round rod is fixedly connected to the movable rod, with the end of the round rod away from the movable rod located in the corrugated guide groove on the guide wheel. Several scrapers are rotatably connected to the movable rod. Torsion springs are connected between the top of the movable rod and each of the scrapers. A collection box is fixedly connected to the support frame. An air pump is fixedly connected to the top of the collection box and communicates with the collection box. A feed pipe is fixedly connected to the air pump and communicates with the air pump.

[0010] Furthermore, it also includes a fixing rod and a connecting rod. The fixing rod is fixedly connected between the two mounting plates, and the connecting rod is fixedly connected to each of the several scrapers. The fixing rod and the several connecting rods are rotatably connected.

[0011] Furthermore, it also includes a dosage control component, which is disposed on the soil loosening slurry. The dosage control component includes a rotating disk, and the rotating disk is fixedly connected to the end of the soil loosening slurry away from the guide groove wheel. Four sliding blocks are slidably connected to the rotating disk, and a return spring is connected between the rotating disk and the four sliding blocks. An elastic ring is sleeved between the four sliding blocks. A limit block is fixedly connected to the lower part of the medicine tank, and a movable frame is slidably connected to the limit block. The movable frame is fixedly connected to the baffle, and the end of the movable frame away from the baffle contacts the elastic ring. A return spring is connected between the movable frame and the limit block.

[0012] Furthermore, the elastic ring is made of rubber.

[0013] Furthermore, it also includes a soil-breaking assembly, which is mounted on the mounting plate. The soil-breaking assembly includes a limiting frame, with limiting frames fixedly connected to both mounting plates. A sliding rod is slidably connected between the two limiting frames. A support spring is connected between the sliding rod and the two limiting frames. A slotted rod is fixedly connected to the end of the sliding rod away from the limiting frame. A slotted rod has a slot. A short rod is fixedly connected to the end of the guide wheel away from the loosening impeller. The end of the short rod away from the guide wheel is located in the slot on the slotted rod. A pressure frame is slidably connected to the sliding rod. Two compression springs are connected between the pressure frame and the sliding rod. The compression springs are sleeved on the pressure frame.

[0014] Furthermore, it also includes a rake, with the rake fixedly connected between the two mounting plates.

[0015] Furthermore, the lower part of the rake is provided with several rake teeth.

[0016] The beneficial effects of this invention are as follows: First, the operator simultaneously activates four hydraulic push rods, a servo motor, and an air pump, and pulls the baffle to move. The baffle no longer blocks the discharge port at the bottom of the reagent tank. The downward movement of the two mounting plates will jointly drive the support frame, reagent tank, and loosening slurry downward. At the same time, the loosening slurry will turn over and loosen the saline-alkali land, and several scrapers will scrape off the carbonate on the surface of the saline-alkali land. The air pump will draw the scraped carbonate from the surface of the saline-alkali land into the collection box through the feed pipe. Then, the repair agent in the reagent tank will be discharged through the discharge port at the bottom of the reagent tank. The agent is dropped downwards into the loosened soil of the saline-alkali land. The agent neutralizes and repairs the soil. In this way, the soil is turned over and loosened by the soil loosening slurry, and the agent is applied to the loosened soil through the agent tank. This allows the soil to come into full contact with the agent, thereby neutralizing and repairing the soil. At the same time, several scrapers scrape off the carbonate on the surface of the saline-alkali land and collect the carbonate through the feed pipe. This achieves the synchronization of soil loosening and agent application, improving the efficiency of saline-alkali land restoration.

[0017] When the round rod drives the movable rod to move horizontally back and forth, the movable rod will drive several scrapers to swing back and forth, which will increase the scraping range of the scrapers and make the scrapers scrape off the carbonates on the surface of the saline-alkali land more thoroughly, thus making the restoration effect of the saline-alkali land better.

[0018] When the output shaft of the servo motor drives the loosening paddle to rotate, the movement of the movable frame will cause the baffle to move away from the loosening paddle, so that the baffle no longer blocks the discharge port at the bottom of the agent tank. In this way, by moving the baffle closer to or away from the loosening paddle through the sliding frame, the baffle can be opened automatically, further improving the restoration efficiency of saline-alkali land.

Detailed Implementation

[0031] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0032] Example 1: An ecological restoration device for saline-alkali land, such as Figures 1-11 As shown, the device includes a frame 1 with four wheels at its bottom. Four hydraulic push rods 2 are bolted to the frame 1. Two hydraulic push rods 2 form a group, and a mounting plate 3 is bolted between the bottom of the telescopic rods of the two hydraulic push rods in the same group. The two mounting plates 3 are symmetrically arranged. A support frame 4 is bolted between the tops of the two mounting plates 3. A medicine tank 5 is bolted to the support frame 4. The medicine tank is used to hold repair agents. A discharge port is opened at the bottom of the medicine tank 5 for discharging the repair agents. A baffle 6 is slidably connected to the discharge port at the bottom of the medicine tank 5 to block it. One of the mounting plates 3 is equipped with a soil-turning component for loosening the soil in saline-alkali land. A saline-alkali soil collection component is also installed on the soil-turning component to collect carbonates from the surface of the saline-alkali land. The saline-alkali soil is connected to the support frame 4.

[0033] The soil-tillage assembly includes a servo motor 71. One of the mounting plates 3 is bolted to the side away from the reagent tank 5. The output shaft of the servo motor 71 passes through one of the mounting plates 3. A pulley 72 is connected to the output shaft of the servo motor 71 via a flat key. A soil-loosening paddle 73 is rotatably connected between the two mounting plates 3. The soil-loosening paddle 73 is equipped with a drive wheel. The soil-loosening paddle 73 is used to loosen the soil in saline-alkali land. A drive belt 74 is fitted between the pulley 72 and the drive wheel of the soil-loosening paddle 73.

[0034] The saline-alkali soil collection assembly includes a guide wheel 81. One end of the loosening paddle 73 is bolted to the guide wheel 81. The guide wheel 81 has a corrugated guide groove. A movable rod 82 is slidably connected between the two mounting plates 3. A round rod 83 is welded to the movable rod 82. The end of the round rod 83 away from the movable rod 82 is located in the corrugated guide groove on the guide wheel 81. Several scrapers 84 are rotatably connected to the movable rod 82. The scrapers 84 are used to scrape off the carbonates on the surface of the saline-alkali soil. The top of the movable rod 82 and several scrapers 84 are connected by hooks to torsion springs 85. A collection box 86 is bolted to the support frame 4. A vacuum pump 87 is bolted to the top of the collection box 86. The vacuum pump 87 is used to extract carbonates from the surface of the saline-alkali land. The vacuum pump 87 is connected to the collection box 86. A feed pipe 88 is connected to the vacuum pump 87 through a flange. The feed pipe 88 is used to transport carbonates from the surface of the saline-alkali land. The feed pipe 88 is connected to the vacuum pump 87.

[0035] Initially, the medicine tank 5 contains an appropriate amount of repair agent. A baffle 6 blocks the discharge port at the bottom of the medicine tank 5. The frame 1 is connected to the tractor via a hook, and the tractor will move the device. First, the operator simultaneously activates the four hydraulic push rods 2, the servo motor 71, and the air pump 87, and pulls the baffle 6 to move. The baffle 6 no longer blocks the discharge port at the bottom of the medicine tank 5. The extension rods of the two hydraulic push rods 2 in the same group extend and together move the mounting plate 3 downwards. The downward movement of the two mounting plates 3 together moves the support frame 4, the medicine tank 5, the loosening slurry 73, etc., downwards. The saline-alkali soil will contact the bottom of the loosening slurry 73 and several scrapers 84. At the same time, the output shaft of the servo motor 71 will... The rotating pulley 72 drives the loosening paddle 73 via the transmission belt 74. The loosening paddle 73 loosens the soil in the saline-alkali land. The rotation of the loosening paddle 73 drives the guide wheel 81, which in turn pushes the round rod 83 to move horizontally back and forth. This horizontal movement of the round rod 83 drives the movable rod 82 to move horizontally back and forth. This horizontal movement of the movable rod 82 drives several scrapers 84 and several torsion springs 85 to move horizontally back and forth. The scrapers 84 scrape off the carbonates on the surface of the saline-alkali land. The air pump 87 draws the scraped carbonates into the collection box 86 through the feed pipe 88. Then, the repair agent in the agent tank 5 is... The chemicals fall through the discharge port at the bottom of the chemical tank 5 into the loosened soil of the saline-alkali land. The chemicals neutralize and repair the soil. After the soil is repaired, the workers will turn off the servo motor 71 and the vacuum pump 87, and simultaneously adjust the four hydraulic push rods 2. The retraction of the telescopic rods of two hydraulic push rods 2 in the same group will move the mounting plate 3 upward and reset it. The reset of the two mounting plates 3 will jointly move the support frame 4, chemical tank 5, baffle 6, servo motor 71, pulley 72, loosening paddle 73, transmission belt 74, guide groove wheel 81, movable rod 82, round rod 83, scraper 84, torsion spring 85, collection box 86, vacuum pump 87 and feed pipe 88 upward and reset them. Then, the staff will push the baffle 6 to move and reset, and the baffle 6 will block the discharge port at the bottom of the agent tank 5 again. Then, the staff will open the collection box 86 to collect the carbonate and close the collection box 86 again. In this way, the soil of the saline-alkali land is turned over and loosened by the soil loosening slurry 73, and the remediation agent is applied to the loosened saline-alkali land soil through the agent tank 5, so that the saline-alkali land soil and the remediation agent can be in full contact, thereby neutralizing and remediating the saline-alkali land soil. At the same time, the carbonate on the surface of the saline-alkali land is scraped off by several scrapers 84 and collected through the feed pipe 88, thereby realizing the synchronization of soil loosening and chemical application of saline-alkali land and improving the remediation efficiency of saline-alkali land.

[0036] Example 2: Based on Example 1, such as Figure 8As shown, it also includes a fixing rod 91 and a connecting rod 92. The fixing rod 91 is welded between the two mounting plates 3, and the connecting rod 92 is welded on each of the scrapers 84. The fixing rod 91 and the connecting rod 92 are rotatably connected.

[0037] When the round rod 83 drives the movable rod 82 to move horizontally back and forth, the movable rod 82 will drive several scrapers 84 to swing back and forth. The torsion spring 85 will be twisted or reset continuously. The back and forth swing of the scrapers 84 will drive the connecting rod 92 to rotate back and forth, thereby increasing the scraping range of the scrapers 84. This allows the scrapers 84 to scrape off the carbonates on the surface of the saline-alkali land more thoroughly, thus improving the restoration effect of the saline-alkali land.

[0038] Example 3: Based on Example 2, such as Figure 6 and Figure 7 As shown, it also includes a dosage control component, which is mounted on the soil loosening paddle 73. The dosage control component includes a rotating disk 101. The end of the soil loosening paddle 73 away from the guide groove wheel 81 is bolted to the rotating disk 101. Four sliding blocks 102 are slidably connected to the rotating disk 101. Each of the four sliding blocks 102 is connected to a return spring 103 via a hook. An elastic ring 104 made of rubber is fitted between the four sliding blocks 102. A limit block 105 is welded to the lower part of the medicine tank 5. A movable frame 106 is slidably connected to the limit block 105. The movable frame 106 is fixedly connected to the baffle 6. The end of the movable frame 106 away from the baffle 6 contacts the elastic ring 104. A return spring 107 is connected to the movable frame 106 and the limit block 105 via a hook.

[0039] When the output shaft of the servo motor 71 drives the tiller 73 to rotate, the tiller 73 drives the rotating disk 101 to rotate. The rotation of the rotating disk 101 drives the four sliding blocks 102 and the four return springs 103 to rotate. The rotation of the four sliding blocks 102 together drives the elastic ring 104 to rotate. As the tiller 73 drives the four sliding blocks 102 to rotate, the four sliding blocks 102 will move away from each other under the action of centrifugal force. The return springs 103 will be compressed. The movement of the four sliding blocks 102 will together expand the elastic ring 104, causing the elastic ring 104 to deform. The elastic ring 104 will push the movable frame 106 to move away from the sliding blocks 102. The return spring 107 will be compressed. The movement of the movable frame 106 will drive the baffle 6 to move away from the sliding blocks 102. The movement away from the loosening slurry 73 causes the baffle 6 to no longer block the discharge port at the bottom of the reagent tank 5. When the servo motor 71 is turned off, the reset spring 103 will reset. The reset spring 103 will drive the four sliding blocks 102 to move closer to each other and reset. The elastic ring 104 will rebound and the return spring 107 will reset. The reset spring 107 will drive the movable frame 106 to move closer to the sliding block 102 and reset. The reset frame 106 will drive the baffle 6 to move closer to the loosening slurry 73 and reset. The baffle 6 will then block the discharge port at the bottom of the reagent tank 5 again. In this way, by moving the baffle 6 closer to or away from the loosening slurry 73 through the sliding frame, the baffle 6 can be opened automatically, further improving the restoration efficiency of saline-alkali land.

[0040] Example 4: Based on Example 3, such as Figure 7 and Figure 9 As shown, it also includes a soil-breaking assembly, which is mounted on the mounting plate 3. The soil-breaking assembly includes a limiting frame 111, and limiting frames 111 are welded to both mounting plates 3. A sliding rod 112 is slidably connected between the two limiting frames 111. A support spring 113 is connected to the sliding rod 112 and the two limiting frames 111 via a hook. A slotted rod 114 is welded to the end of the sliding rod 112 away from the limiting frame 111. A slot is formed on the slotted rod 114. The guide wheel 81 is located away from... One end of the loosening paddle 73 is welded with a short rod 115. The end of the short rod 115 away from the guide groove wheel 81 is located in the groove on the groove rod 114. The groove on the groove rod 114 is used to guide the short rod 115. A pressure frame 116 is slidably connected to the sliding rod 112. The pressure frame 116 is used to crush large clods of soil turned over on the saline-alkali land. Two compression springs 117 are connected between the pressure frame 116 and the sliding rod 112 by hooks. The compression springs 117 are sleeved on the pressure frame 116.

[0041] When the loosening paddle 73 drives the guide wheel 81 to rotate, the guide wheel 81 drives the short rod 115 to rotate. The rotation of the short rod 115 pushes the slotted rod 114 to move up and down reciprocally. The up and down reciprocating movement of the slotted rod 114 drives the sliding rod 112 to move up and down reciprocally. The support spring 113 is continuously compressed or reset. The up and down reciprocating movement of the sliding rod 112 drives the pressure frame 116 to move up and down reciprocally. The pressure frame 116 continuously crushes the soil that has been turned over in the saline-alkali land, which allows the soil in the saline-alkali land to come into more sufficient contact with the remediation agent, further improving the remediation effect of the saline-alkali land.

[0042] Example 5: Based on Example 4, such as Figures 1-5 As shown, it also includes a rake 12, which is bolted between the two mounting plates 3. The rake 12 has several rake teeth on its lower part.

[0043] When the telescopic rods of the two electric push rods in the same group extend and jointly drive the mounting plate 3 to move downward, the two mounting plates 3 will jointly drive the rake 12 to move downward. The rake 12 will rake the soil crushed by the pressing frame 116 on the saline-alkali land, thereby cutting off the capillary water in the soil from transporting salt to the surface and preventing salt reversion.
