Abstract

The present invention relates to the technical field of land irrigation, and specifically relates to an irrigation device for land treatment, including a chassis, a dredging mechanism, a covering mechanism, a ramming mechanism, a water storage tank and an irrigation head. The dredging mechanism is rotatably arranged at the end of the chassis and is used for opening a drainage ditch. The covering mechanism is rotatably arranged at the bottom of the chassis and is used for filling the drainage ditch with soil. The ramming mechanism is movably arranged at one end of the chassis away from the dredging mechanism and is used for compacting the soil. Through the rotation of the hexagonal block in the dredging mechanism and further through the connection of the chute, slider and torsion shaft, the shovel is driven to rotate to excavate the drainage ditch.

At the same time, the irrigation water cannot flow along the land surface inside the drainage ditch, effectively avoiding the waste of irrigation water.

Description

Technical Field

[0001] The present invention relates to the technical field of land irrigation, and specifically relates to an irrigation device for land treatment. Background Art

[0002] In the process of land improvement, in order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply sufficient water to the crops. Under natural conditions, due to insufficient precipitation or uneven distribution, the water requirements of the crops cannot be met. Therefore, it is necessary to artificially irrigate to make up for the deficiency of natural rainfall.

[0003] Referring to a Chinese patent with the application number 202210062955.4, a farmland irrigation device for land improvement is disclosed. By the operation of a double-shaft motor, two sector gears rotate, and then through the first gear and the second gear, the first nozzle and the second nozzle intermittently rotate 180 degrees to fully spray the farmland, enabling the crops to better absorb water and achieving a better irrigation effect. Nevertheless, the above-mentioned farmland irrigation device for land improvement sprays irrigation water onto the ground surface, which easily causes the irrigation water to flow on the ground surface, is not conducive to the absorption of plant roots, and a part of the irrigation water is directly evaporated by sunlight before it can penetrate downward, resulting in low utilization rate of irrigation water resources. Therefore, we propose an irrigation device for land treatment to solve the above technical problems. Summary of the Invention

[0066] Compared with the prior art, the beneficial effects of the present invention are:

[0067] 1. In the present invention, the rotation of the hexagonal block in the diversion mechanism further drives the rotation of the shovel through the connection of the chute, slider, and torsion shaft to excavate the diversion ditch. As the device moves, the built-in pump inside the water storage tank pumps irrigation water through the conduit into the irrigation head, and finally irrigates the excavated diversion ditch from the bottom of the irrigation head, so as to infiltrate downward, which is beneficial for the absorption of plant roots. At the same time, the irrigation water cannot flow along the land surface inside the diversion ditch, effectively avoiding the waste of irrigation water.

[0068] 2. In the present invention, after the shovel in the diversion mechanism shovels up the soil and moves along the chute, it drives the reversing gear to move together. When the reversing gear meshes with the reversing rack, the torque limiting block just separates from the torque limiting bar. At this time, the reversing gear rolls along the surface of the reversing rack and drives the shovel to turn over through the torsion shaft, pouring the shoveled soil beside the diversion ditch, preventing the shoveled soil from falling into the diversion ditch again. After the diversion ditch is filled with irrigation water, the covering mechanism of the device scrapes the soil beside the diversion ditch into the diversion ditch to avoid direct sunlight on the irrigation water, so as to reduce the evaporation of irrigation water and improve the utilization rate of irrigation water.

[0069] 3. In the present invention, the rotation of the cam is also driven by the rotating shaft, pushing the guide wheel downward, causing the lever to turn over along the positioning pin, making the path groove tilt upward, pushing the pin and the slide bar to slide upward along the guide rail, further driving the ramming frame, ramming rod, ramming plate and guide rod to move upward, compressing the third spring. And under the continuous rotation of the cam and the resilience of the third spring, the lever rotates reciprocally along the positioning pin, so that the ramming plate swings up and down reciprocally, compacting the soil covering the diversion ditch and preventing the soil layer covering the diversion ditch from being blown away by the wind.

Detailed implementation manners

[0083] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0084] Please refer to Figures 1 to 12 , the technical solutions provided by the present invention specifically include the following embodiments:

[0085] An irrigation device for land treatment includes a chassis 100, a dredging mechanism 200, a covering mechanism 300, a ramming mechanism 400, a water storage tank 500 and an irrigation head 600. The dredging mechanism 200 is rotatably arranged at the end of the chassis 100 for opening a drainage ditch. The covering mechanism 300 is rotatably arranged at the bottom of the chassis 100 for filling the drainage ditch with soil. The ramming mechanism 400 is movably arranged at one end of the chassis 100 away from the dredging mechanism 200 for compacting the soil. The water storage tank 500 is fixedly arranged on the top of the chassis 100 for storing water. An in-built pump is arranged inside the water storage tank 500. The irrigation head 600 is fixedly installed inside the chassis 100 for irrigating the land. The input end of the irrigation head 600 is connected to the output end of the in-built pump inside the water storage tank 500 through a pipeline. It further includes a wheel frame 700, and the wheel frame 700 is fixedly installed on the outer side surface of the chassis 100 and the number is four. Rollers 800 are rotatably installed on all four wheel frames 700.

[0086] Further, specifically refer to Figures 4 to 7 as shown in

[0087] The dredging mechanism 200 includes a rotating shaft 201, a hexagonal block 202, a chute 203, a slider 204, a torsion shaft 205, a shovel 206, a flipping gear 207, a flipping rack 208, a first fixing plate 209, a permanent magnet 2010, a torsion limiting block 2011, a torsion limiting strip 2012, a first spring 2013, an electromagnetic block 2014, a first driven belt pulley 2015, a single-cylinder gasoline engine 2016, a first driving belt pulley 2017 and a first power belt 2018. The rotating shaft 201 is symmetrically and rotatably installed inside the chassis 100. The hexagonal block 202 is fixedly installed between the left and right rotating shafts 201 and is concentric with the rotating shaft 201. The chute 203 is opened on the six prism faces of the hexagonal block 202. The slider 204 is slidably installed inside the chute 203. The torsion shaft 205 is rotatably installed inside the slider 204. The shovel 206 is fixedly installed at one end of the torsion shaft 205 away from the center of the hexagonal block 202. The flipping gear 207 is fixedly installed at one end of the torsion shaft 205 away from the shovel 206. The flipping rack 208 is fixedly installed on the inner side faces of the six prism faces of the hexagonal block 202, and the positions and specifications correspond to the six flipping gears 207 respectively. The first fixing plate 209 is fixedly installed on one side of the slider 204 close to the chassis 100 and is located inside the hexagonal block 202. The permanent magnet 2010 is fixedly installed on one side face of the first fixing plate 209 away from the slider 204. The first spring 2013 is fixedly installed on one side face of the slider 204 away from the first fixing plate 209, and one end of the first spring 2013 away from the slider 204 is fixedly connected to the inner wall of one side of the hexagonal block 202. The electromagnetic block 2014 is fixedly installed on one side face of the chassis 100 close to the hexagonal block 202 and corresponds to the position of the permanent magnet 2010. The magnetism of the electromagnetic block 2014 is opposite to that of the permanent magnet 2010. The magnetic force between the electromagnetic block 2014 and the first spring 2013 is greater than the maximum elastic force of the first spring 2013. The torsion limiting block 2011 is fixedly installed on the outer wall of the torsion shaft 205. The torsion limiting strip 2012 is fixedly installed on the six prism faces of the hexagonal block 202 and is located outside the opening of the chute 203. The length of the torsion limiting strip 2012 corresponds to the tooth length of the flipping rack 208, and the side face of the torsion limiting strip 2012 close to the chute 203 is in sliding contact with the outer side face of the torsion limiting block 2011. The first driven belt pulley 2015 is fixedly installed at one end of one of the rotating shafts 201 away from the hexagonal block 202. The single-cylinder gasoline engine 2016 is fixedly installed on the top of the chassis 100. The first driving belt pulley 2017 is fixedly installed on the output shaft of the single-cylinder gasoline engine 2016. The first power belt 2018 is sleeved between the first driven belt pulley 2015 and the first driving belt pulley 2017.

[0088] Specifically, the device is towed by a tractor, and with the support of the four rollers 800 at the bottom of the device, the device moves on the land. Meanwhile, the single-cylinder gasoline engine 2016 is started, and the output shaft of the single-cylinder gasoline engine 2016 drives the first driving pulley 2017 to rotate. Further, under the connection of the first power belt 2018, the first driven pulley 2015 is driven to rotate. The rotation of the first driven pulley 2015 further drives the hexagonal block 202 to rotate through the rotating shaft 201. The rotation of the hexagonal block 202 further drives the shovel 206 to rotate and excavate the drainage ditch through the connection of the chute 203, the slider 204, and the torsion shaft 205. As the device moves, the built-in pump inside the water storage tank 500 pumps the irrigation water into the irrigation head 600 through the conduit, and finally irrigates it into the excavated drainage ditch from the bottom of the irrigation head 600, so as to infiltrate downward, which is beneficial for the plant roots to absorb. At the same time, the irrigation water cannot flow along the land surface inside the drainage ditch, effectively avoiding the waste of irrigation water.

[0089] It should be noted that during the process of the hexagonal block 202 driving the shovel 206 to rotate, the excavated soil is shoveled upward. As the shovel 206 with soil rotates, a corresponding slider 204 rotates together, and drives the first fixing plate 209 and the permanent magnet 2010 to rotate to the position of the electromagnetic block 2014. Then, through the magnetic force between the electromagnetic block 2014 and the permanent magnet 2010, the permanent magnet 2010 is pushed to move away from the electromagnetic block 2014, further driving the first fixing plate 209 and the slider 204 to slide along the chute 203, causing the first spring 2013 to be compressed and store energy. At the same time, the slider 204 also drives the torsion shaft 205, the shovel 206 and the flipping gear 207 to move together. Since the shovel 206 moves along the chute 203, the shovel 206 deviates above the drainage ditch. And during the movement of the torsion shaft 205 along the chute 203, it also drives the torque-limiting block 2011 to move together, so that the outer side surface of the torque-limiting block 2011 slides along the surface of the torque-limiting strip 2012, ensuring that the torsion shaft 205 does not rotate, that is, the shovel 206 does not rotate, to prevent the shoveled soil from falling back into the drainage ditch again. As the torsion shaft 205 continues to move, when the flipping gear 207 meshes with the flipping rack 208, the torque-limiting block 2011 just separates from the torque-limiting strip 2012. At this time, the flipping gear 207 rolls along the surface of the flipping rack 208, and drives the shovel 206 to flip through the torsion shaft 205, pouring the shoveled soil beside the drainage ditch. Until the permanent magnet 2010 rotates with the hexagonal block 202 and is misaligned with the electromagnetic block 2014, the magnetic force disappears, and the resilience of the first spring 2013 drives the slider 204 to slide back along the chute 203. At this time, the flipping gear 207 rolls in the reverse direction along the flipping rack 208, driving the torsion shaft 205 and the shovel 206 to flip back to the original position. When the flipping gear 207 disengages from the flipping rack 208, the torque-limiting block 2011 contacts the torque-limiting strip 2012 again, limiting the torque of the torsion shaft 205 again to prevent the shovel 206 from rotating during the soil-shoveling process.

[0090] Furthermore, specifically referring to Figure 9 and Figure 10 as shown:

[0091] The covering mechanism 300 includes a first bearing bracket 301, a covering shaft rod 302, a covering brush 303, a second driven pulley 304, a second bearing bracket 305, a transmission rod 306, a second driving pulley 307, a second power belt 308, a driven helical gear 309 and a driving helical gear 3010. The first bearing bracket 301 is fixedly installed inside the chassis 100 and the number thereof is two. The covering shaft rod 302 is rotatably installed between the two first bearing brackets 301. The covering brush 303 is fixedly installed on the outer wall of the covering shaft rod 302. The second driven pulley 304 is fixedly installed at one end of the covering brush 303 close to the guiding mechanism 200. The second bearing bracket 305 is fixedly installed on the outer side surface of the chassis 100 and the number thereof is two. The transmission rod 306 is rotatably installed inside the two second bearing brackets 305. The second driving pulley 307 is fixedly installed on the outer wall of the transmission rod 306 and is correspondingly positioned with the second driven pulley 304. The second power belt 308 is sleeved between the second driven pulley 304 and the second driving pulley 307. The driven helical gear 309 is fixedly installed on the outer wall of the transmission rod 306 and at one end close to the guiding mechanism 200. The driving helical gear 3010 is fixedly installed on the outer wall of a rotating shaft 201 far from the first driven pulley 2015 and is located at the top of the driven helical gear 309. The driving helical gear 3010 and the driven helical gear 309 are meshed with each other.

[0092] Specifically, the rotation of the rotating shaft 201 also drives the driving helical gear 3010 to rotate together, further driving the meshed driven helical gear 309 to rotate. The rotation of the driven helical gear 309 drives the transmission rod 306 and the second driving pulley 307 to rotate inside the two second bearing brackets 305. The rotation of the second driving pulley 307 drives the second driven pulley 304 and the covering shaft rod 302 to rotate along the two first bearing brackets 301 through the connection of the second power belt 308, thereby driving the covering brush 303 to rotate. When the irrigation head 600 finishes irrigation in the diversion ditch during the movement of the device, the rotating covering brush 303 scrapes the soil beside the diversion ditch into the diversion ditch to cover the diversion ditch, avoiding direct sunlight on the irrigation water to reduce the evaporation of the irrigation water and improve the utilization rate of the irrigation water.

[0093] Further, specifically referring to Figure 11 and Figure 12 as shown in:

[0094] The ramming mechanism 400 includes a positioning axle pin 401, a lever 402, a wheel groove 403, a guide wheel 404, a cam 405, a path groove 406, a guide rail 407, a slide bar 408, a bolt 409, a ramming frame 4010, a ramming rod 4011, a fixing cap 4012, a second spring 4013, a third spring 4014, a guide rod 4015, a second fixing plate 4016 and a ramming plate 4017. The positioning axle pin 401 is fixedly installed in the middle of the two opposite side surfaces of the chassis 100. The levers 402 are respectively hinged on the outer walls of the two positioning axle pins 401. The wheel groove 403 is opened at one end of the lever 402 close to the dredging mechanism 200. The guide wheel 404 is rotatably installed inside the wheel groove 403. The cam 405 is fixedly installed on the outer walls of the two rotating shafts 201, and the bottom of the outer wall of its top abuts against the bottom of the outer wall of the guide wheel 404. The path groove 406 is opened at one end of the lever 402 away from the wheel groove 403. The guide rail 407 is vertically and fixedly installed on one of the two opposite side surfaces of the chassis 100 and at the end away from the dredging mechanism 200. The slide bars 408 are respectively slidably installed around the two guide rails 407. The bolt 409 is fixedly installed on the upper part of the opposite sides of the two slide bars 408, and the bolt 409 is slidably inserted into the path groove 406. The ramming frame 4010 is fixedly installed at the bottom of the two slide bars 408. The ramming rod 4011 is vertically slidably installed inside the ramming frame 4010 and penetrates through the ramming frame 4010. The fixing cap 4012 is fixedly installed at the top of the ramming rod 4011. The second spring 4013 is sleeved around the ramming rod 4011 and is fixedly installed between the bottom of the fixing cap 4012 and the top of the ramming frame 4010. The ramming plate 4017 is fixedly installed at the bottom of the ramming rod 4011. The third springs 4014 are distributed left and right and fixedly installed at the top of the ramming frame 4010. The guide rods 4015 are distributed left and right and fixedly installed at the top of the ramming frame 4010 and are located inside the two third springs 4014. The second fixing plate 4016 is fixedly installed at one end of the top of the chassis 100 away from the dredging mechanism 200. The bottom of the second fixing plate 4016 is fixedly connected to the top of the two third springs 4014. The guide rod 4015 movably penetrates through the inside of the second fixing plate 4016.

[0095] Specifically, the rotation of the rotating shaft 201 also drives the cam 405 to rotate, pushing the guide wheel 404 downward, causing the lever 402 to flip along the positioning axle pin 401, making the path groove 406 tilt upward, pushing the bolt 409 and the slide bar 408 to slide upward along the guide rail 407, further driving the ramming frame 4010, the ramming rod 4011, the ramming plate 4017 and the guide rod 4015 to move upward, compressing the third spring 4014, and under the continuous rotation of the cam 405 and the resilience of the third spring 4014, the lever 402 rotates reciprocally along the positioning axle pin 401, so that the ramming plate 4017 swings up and down reciprocally, compacting the soil covering the drainage ditch and preventing the soil layer covering the drainage ditch from being blown away by the wind.

[0096] When a land treatment irrigation device of this solution is working, the device is towed by a tractor and, with the support of four rollers 800 at the bottom of the device, the device moves on the land. At the same time, the single-cylinder gasoline engine 2016 is started. The output shaft of the single-cylinder gasoline engine 2016 drives the first driving pulley 2017 to rotate. Further, through the connection of the first power belt 2018, the first driven pulley 2015 is driven to rotate. The rotation of the first driven pulley 2015 further drives the hexagonal block 202 to rotate through the rotating shaft 201. The rotation of the hexagonal block 202 further drives the shovel 206 to rotate and excavate the drainage ditch through the connection of the chute 203, the slider 204, and the torsion shaft 205. As the device moves, the built-in pump inside the water storage tank 500 pumps the irrigation water into the irrigation head 600 through the conduit, and finally irrigates it into the excavated drainage ditch from the bottom of the irrigation head 600, so as to penetrate downward, which is beneficial for the plant roots to absorb. At the same time, the irrigation water cannot flow along the land surface inside the drainage ditch, effectively avoiding the waste of irrigation water;

[0097] Meanwhile, during the process of the hexagonal block 202 driving the shovel 206 to rotate, the excavated soil is shoveled upward. As the shovel 206 with soil rotates, a corresponding slider 204 rotates together, driving the first fixing plate 209 and the permanent magnet 2010 to rotate to the position of the electromagnetic block 2014. Then, through the magnetic force between the electromagnetic block 2014 and the permanent magnet 2010, the permanent magnet 2010 is pushed to move away from the electromagnetic block 2014, further driving the first fixing plate 209 and the slider 204 to slide along the chute 203, causing the first spring 2013 to be compressed and store energy. At the same time, the slider 204 also drives the torsion shaft 205, the shovel 206, and the reversing gear 207 to move together. Since the shovel 206 moves along the chute 203, the shovel 206 deviates above the drainage ditch. And during the movement of the torsion shaft 205 along the chute 203, the torque-limiting block 2011 is also driven to move together, making the outer side of the torque-limiting block 2011 slide along the surface of the torque-limiting strip 2012 to ensure that the torsion shaft 205 does not rotate, that is, the shovel 206 does not rotate, preventing the shoveled soil from falling back into the drainage ditch again. As the torsion shaft 205 continues to move, when the reversing gear 207 meshes with the reversing rack 208, the torque-limiting block 2011 just separates from the torque-limiting strip 2012. At this time, the reversing gear 207 rolls along the surface of the reversing rack 208 and drives the shovel 206 to turn over through the torsion shaft 205, dumping the shoveled soil beside the drainage ditch. Until the permanent magnet 2010 rotates with the hexagonal block 202 and is misaligned with the electromagnetic block 2014, the magnetic force disappears, and the resilience of the first spring 2013 drives the slider 204 to slide back along the chute 203. At this time, the reversing gear 207 rolls in the reverse direction along the reversing rack 208, driving the torsion shaft 205 and the shovel 206 to turn back to the original position. When the reversing gear 207 disengages from the reversing rack 208, the torque-limiting block 2011 contacts the torque-limiting strip 2012 again to limit the torque of the torsion shaft 205 again to prevent the shovel 206 from rotating during the process of shoveling soil;

[0098] During this period, the rotation of the rotating shaft 201 also drives the active helical gear 3010 to rotate together, further driving the meshing driven helical gear 309 to rotate. The rotation of the driven helical gear 309 drives the transmission rod 306 and the second active pulley 307 to rotate inside the two second bearing brackets 305. The rotation of the second active pulley 307 drives the second driven pulley 304 and the covering shaft rod 302 to rotate along the two first bearing brackets 301 through the connection of the second power belt 308, thereby driving the covering brush 303 to rotate. When the irrigation head 600 finishes irrigating the guide ditch during the movement of the device, the rotating covering brush 303 scrapes the soil beside the guide ditch into the guide ditch to cover the guide ditch, avoiding direct sunlight on the irrigation water to reduce the evaporation of the irrigation water. At the same time, as the device continues to move, the rotating shaft 201 also drives the cam 405 to rotate, pushing the guide wheel 404 downward, causing the lever 402 to flip along the positioning pin 401, making the path groove 406 tilt upward, pushing the pin 409 and the slide bar 408 to slide upward along the guide rail 407, further driving the ramming frame 4010, the ramming rod 4011, the ramming plate 4017 and the guide rod 4015 to move upward, compressing the third spring 4014. And under the continuous rotation of the cam 405 and the resilience of the third spring 4014, the lever 402 rotates reciprocally along the positioning pin 401, so that the ramming plate 4017 swings up and down reciprocally to compact the soil covering the guide ditch, preventing the wind from blowing away the soil layer covering the guide ditch.

[0099] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
