Description

Technical Field

[0001] The present application relates to the field of agricultural technology, and in particular to a device for removing soil continuous cropping obstacles in facility cultivation. Background Art

[0002] Facility cultivation, also known as facility horticulture, refers to the use of specific facilities (multi-span greenhouses, solar greenhouses, plastic greenhouses, small arch sheds and breeding sheds) in seasons (cold or hot) or regions where open fields are not suitable for the growth of horticultural crops, to artificially create an environment suitable for crop growth, so as to produce high-quality, high-yield and stable-yield vegetables, flowers, fruits and other horticultural products. In facility cultivation, various factors such as excessive nutrient consumption, deterioration of soil physical and chemical properties, increase in pests and diseases, and accumulation of toxic substances (including allelopathic substances, etc.) caused by continuous cropping will lead to the adverse effects of abnormal crop growth and development caused by cultivating the same crops or closely related crops on the same soil, which is called soil continuous cropping obstacles. Therefore, in order to maintain crop yields, it is necessary to remove soil continuous cropping obstacles.

[0003] Among them, the method of removing soil continuous cropping obstacles is to spray fertilizer to improve soil fertility, such as a greenhouse continuous cropping obstacle removal device with publication number CN206866043U, including a base, a box body is installed on the upper surface of the base, a partition is provided inside the box body, the partition divides the inside of the box body into a fertilizer tank and an installation tank, a water pump and a battery are installed inside the installation tank, the water outlet of the water pump is fixedly connected with a fixed pipe, the upper end of the fixed pipe is fixedly sleeved with a piston plate, the surface of the fixed pipe and the piston plate are slidably sleeved with a limiting pipe, the upper end of the limiting pipe is fixedly connected with a branch pipe, both ends of the branch pipe are fixedly sleeved with an internal threaded joint, the surface of the internal threaded joint is threadedly connected with an external threaded joint, and the middle part of the side of the external threaded joint is rotated to sleeve an extension pipe. The greenhouse continuous cropping obstacle removal device can increase the fertility of the land, remove the continuous cropping obstacles inside the greenhouse, and avoid the situation where the quality of vegetables decreases or cannot be cultivated.

[0004] However, the above-mentioned prior art has some defects in removing soil continuous cropping obstacles: first, in the process of spraying fertilizer water, since the nozzle sprays from top to bottom, if it encounters crops with lush branches and leaves, the fertilizer water is easily blocked by the branches and leaves, and thus cannot enter the soil completely; second, the fertilizer water of the above-mentioned prior art is only sprayed on the surface of the soil, so that a part of the fertilizer water cannot penetrate into the soil and evaporates on the soil surface, resulting in insufficient soil fertility or waste of fertilizer; third, due to the continuous planting of crops, a large amount of chemical fertilizers and pesticides are applied to the soil, as well as the roots of plants left in the soil. The plant roots will rot under the action of microorganisms and produce harmful gases, thereby harming the crops, while the above-mentioned prior art can only complete the role of fertilization, and cannot turn the soil, and its effect on removing soil continuous cropping obstacles is very limited.

[0005] Based on this, and according to the above-mentioned viewpoints, the existing technology still has room for improvement in removing soil continuous cropping obstacles in facility cultivation. Summary of the invention

[0039] The following is combined with Figures 1 to 13 This application is described in further detail.

[0040] The embodiment of the present application discloses a device for removing obstacles to continuous cropping in soil for facility cultivation. It is described that the device for removing obstacles to continuous cropping in soil is used for removing obstacles to continuous cropping in citrus soil. In terms of technical effect, it can realize turning over and loosening the citrus soil. At the same time, the present application can also fill fertilizer water into the soil, and the fertilizer water will also be sprayed on the soil surface, thereby removing the obstacles to continuous cropping in the soil through the fertilizer water.

[0041] Reference Figure 1The present embodiment discloses a device for removing obstacles to continuous cropping in soil for facility cultivation, comprising a mobile vehicle 1 and a soil-turning device 2 installed on the mobile vehicle 1, which is used to remove obstacles to continuous cropping in citrus soil; a fertilizer box 3 is installed on the top of the mobile vehicle 1 for storing fertilizer water.

[0042] The tilling equipment 2 includes a swing arm 21 and a swing seat 22. The mobile vehicle 1 is a hollow structure that runs through the left and right, and the swing seats 22 are rotatably arranged on both sides of the mobile vehicle 1. A detachable swing arm 21 is arranged on the side of the swing seat 22 away from the mobile vehicle 1. When the swing seat 22 swings back and forth, it can drive the swing arm 21 to swing synchronously; the adjacent swing arms 21 are also installed in a detachable manner, so that the swing arms 21 can be disassembled and installed, that is, the appropriate number of swing arms 21 can be selected according to actual needs; a tilling mechanism 4 for removing obstacles to continuous cropping of the soil is arranged at the lower end of the swing arm 21, a swing mechanism 5 for driving the swing arm 21 to swing back and forth is arranged in the cavity of the mobile vehicle 1, and a driving mechanism 6 for driving the tilling mechanism 4 to operate is arranged in the cavity of the mobile vehicle 1, and a liquid guide mechanism 7 is arranged between the fertilizer box 3 and the tilling mechanism 4, which is used to fill fertilizer water into the soil, and the fertilizer water will also be sprayed on the soil surface.

[0043] The moving vehicle 1 can be driven by its own electricity or pulled by a tractor. In the specific implementation process, the prepared fertilizer water is placed in the fertilizer box 3 in advance. When the moving vehicle 1 moves in the citrus field, the soil turning mechanism 4 can turn over and loosen the soil in the citrus field with the assistance of the driving mechanism 6. At the same time, the liquid guiding mechanism 7 can pour the fertilizer water in the fertilizer box 3 into the soil and the surface of the soil through the soil turning mechanism 4, and the soil turning mechanism 4 can swing back and forth with the cooperation of the swing mechanism 5 to increase the turning area.

[0044] Reference Figure 2The soil turning equipment 2 includes a rotating column 41 with a hollow structure. The rotating column 41 passes through the swing arm 21 and is rotatably installed with the swing arm 21 through a bearing, so that fertilizer water can pass smoothly from the center and receive the rotation of the mechanism below. A first adjusting rod 42 with a hollow structure is slidably sleeved at the lower end of the rotating column 41. A second adjusting rod 43 with a hollow structure is slidably sleeved at the lower end of the first adjusting rod 42. The first adjusting rod 42 and the second adjusting rod 43 are fixed by a screw. The rotating column 41 can drive the first adjusting rod 42 and the second adjusting rod 43 to rotate synchronously. At the same time, the screw can be adjusted according to actual conditions to control the first adjusting rod 42 and the second adjusting rod The relative distance between the two adjusting rods 43 can change the turning height. A liquid outlet pipe 44 is installed at the lower end of the second adjusting rod 43. After the fertilizer water enters the rotating column 41, it passes through the first adjusting rod 42 and the second adjusting rod 43 in sequence and is sprayed onto the soil through the liquid outlet pipe 44. A turning assembly 45 is arranged on the liquid outlet pipe 44 for turning the soil to loosen the soil and facilitate full contact between the fertilizer water and the soil. A transmission assembly 46 for driving the turning assembly 45 is arranged at the position of the swing arm 21 corresponding to the rotating column 41. A downward pressing assembly 47 is arranged between the first adjusting rod 42 and the rotating column 41, which can drive the turning assembly 45 to penetrate into the soil for turning and breaking the soil.

[0045] In the specific implementation process, the screw between the first adjusting rod 42 and the second adjusting rod 43 is adjusted according to the height of the citrus field to change the distance between the first adjusting rod 42 and the second adjusting rod 43, thereby controlling the height of the soil turning. When the mobile vehicle 1 is moving in the citrus field, the transmission assembly 46 transmits the power of the driving mechanism 6 to the soil turning assembly 45, so that the soil turning assembly 45 can better break the soil. At the same time, the downward pressure assembly 47 can apply force to the soil turning assembly 45 to insert it into the soil, assisting the soil turning assembly 45 to break the soil. At the same time, the liquid guiding mechanism 7 sprays fertilizer water into the soil to improve the efficiency of removing soil continuous cropping obstacles.

[0046] Reference Figure 3 The soil turning assembly 45 includes a sliding sleeve 451, a soil turning blade 452, a soil breaking cone 453, a mounting ring 454 and a blade connecting rod 455. The sliding sleeve 451 is slidably arranged on the second adjusting rod 43 and the liquid outlet pipe 44. A plurality of soil turning blades 452 are evenly hinged on the lower end of the sliding sleeve 451 in the circumferential direction. The sliding sleeve 451 drives the soil turning blade 452 to turn over. An inclined soil breaking cone 453 is arranged at the lower end of the soil turning blade 452 and in the rotation direction of the second adjusting rod 43, which can pierce the soil and turn up the soil, so that fertilizer water can better remove the soil. A mounting ring 454 is arranged at the lower end of the liquid outlet pipe 44 and below the sliding sleeve 451. A blade connecting rod 455 is hinged between the mounting ring 454 and the soil turning blade 452 to help the soil turning over.

[0047] The downward movement of the sliding sleeve 451 can drive the movement of the upper end of the soil-turning blade 452. At the same time, since the soil-turning blade 452 is restricted by the blade connecting rod 455, the soil-turning blade 452 is driven to rotate downward when the sliding sleeve 451 moves downward, so that all the soil-turning blades 452 form a pointed cone with the tip pointing downward, and the soil-turning blades 452 in this state can be smoothly inserted into the soil; when the sliding sleeve 451 moves upward, the soil-turning blade 452 is driven to rotate upward, so that all the soil-turning blades 452 form an "eight" structure, and the soil-turning blades 452 in this state can turn over and break the soil.

[0048] Reference Figure 4 The transmission assembly 46 includes a collar 461, a first connecting rod 462, a second connecting rod 463, an annular seat 464, a support frame 465, a support shaft 466, a limiting frame 467, a limiting shaft 468 and a support frame 469. The collar 461 is rotatably fixed on the sliding sleeve 451 to ensure the relative rotation between the sliding sleeve 451 and the transmission assembly 46. The collar 461 is symmetrically hinged with the first connecting rod 462, and the other end of the first connecting rod 462 is hinged with the second connecting rod 463. The movement of the first connecting rod 462 and the second connecting rod 463 causes the sliding sleeve 451 to slide up and down. An annular seat 464 is rotatably provided on the second adjusting rod 43. A support frame 465 is extended on one side of the annular seat 464 corresponding to the second connecting rod 463. The support frame 465 A support shaft 466 is rotatably installed on the upper part, and the second connecting rod 463 is connected to the support shaft 466. The rotation of the support shaft 466 drives the rotation of the second connecting rod 463, so that the second connecting rod 463 can drive the reciprocating swing of the first connecting rod 462; a limit frame 467 with a hollow middle part is arranged on the upper end of the support frame 465, and a limit shaft 468 is installed at the hollow part of the top of the limit frame 467, and a bearing and suspension frame 469 is arranged at the position of the swing arm 21 corresponding to the limit frame 467. The bearing and suspension frame 469 is slidably matched with the middle part of the limit frame 467, and a limit sliding groove for the sliding of the limit shaft 468 is opened on the bearing and suspension frame 469, which is used to support the annular seat 464 and the support frame 465, and limits the rotation of the annular seat 464 with the rotation of the second adjusting rod 43.

[0049] During the specific implementation process, the rotation of the support shaft 466 drives the rotation of the second connecting rod 463, and the rotation of the second connecting rod 463 drives one end of the first connecting rod 462 to rotate in a circle, so that the first connecting rod 462 can swing back and forth, and then drive the sliding sleeve 451 to slide back and forth on the liquid outlet pipe 44, and change the rotational motion state of the support shaft 466 into a linear motion state of the sliding sleeve 451 reciprocating up and down, which helps the expansion and gathering of the soil-turning blade 452, and then the soil-turning blade 452 in the gathered state can be smoothly inserted into the soil, and the expanded soil-turning blade 452 can turn over and loosen the soil.

[0050] Reference Figure 5A power element 8 for driving the sliding sleeve 451 to slide up and down is provided on the swing arm 21, and the power element 8 includes a sprocket 81, a sprocket frame 82, a fixed shaft 83, a sprocket 84 and a chain 85. A sprocket 81 is fixed to the middle of the support shaft 466, and the sprocket 81 drives the rotation of the support shaft 466. An L-shaped sprocket frame 82 is provided at the lower end of the swing arm 21, and a horizontally arranged fixed shaft 83 is installed on the sprocket frame 82. The sprocket frame 82 is used to install the fixed shaft 83, and a sprocket 84 is fixedly installed on the fixed shaft 83. The sprocket 81 and the sprocket 84 are connected by a chain 85. A tensioner 86 for driving the chain 85 to be tightened is provided at the lower end of the swing arm 21. The tensioner 86 is used to prevent the chain 85 from loosening and falling off due to the change of position of the sprocket 81 due to uneven land.

[0051] Specifically, the tensioner 86 includes a tensioning frame 861, a spring rod 862 and a tensioning wheel 863. The tensioning frame 861 is arranged below the swing arm 21. The swing arm 21 and the tensioning frame 861 are connected by the spring rod 862. The tensioning wheel 863 is rotatably mounted on the lower end of the tensioning frame 861, and the tensioning wheel 863 is connected to the chain 1 85. The spring rod 862 can effectively make the tensioning wheel 863 always mesh with the chain 1 85, thereby adjusting the tension of the chain 1 85.

[0052] During the specific implementation process, the rotation of sprocket two 84 drives sprocket one 81 through chain one 85, and at the same time, the tensioning wheel 863 is also transmitted with chain one 85, and due to the elastic force of the spring rod 862, the tensioning wheel 863 can be pushed to move, ensuring that the tensioning wheel 863 is always engaged with chain one 85, and then ensuring that chain one 85 is always kept in a taut state, so that the power of sprocket two 84 can be smoothly transmitted to sprocket one 81, that is, driving the rotation of the first connecting rod 462.

The adjusting sleeve 471 is sleeved on the rotating column 41, fixed to the swing arm 21 and does not affect the rotation of the rotating column 41. The outer wall of the adjusting sleeve 471 is threadedly connected with a worm gear 472. A guide seat 473 is slidably provided on the adjusting sleeve 471, and the worm gear 472 is located in the guide seat 473. The rotation of the worm gear 472 can cause the worm gear 472 to occur on the outer wall thread of the adjusting sleeve 471. The guide seat 473 is provided with a worm 474 meshing with the worm wheel 472 for moving up and down. The rotation of the worm 474 can rotate the worm wheel 472 meshing therewith. A rotating rod 475 for easy gripping is provided at one end of the worm 474. A lower pressure ring 476 sleeved on the adjusting sleeve 471 is provided at the lower end of the guide seat 473. A downward pressure spring 477 is provided between the lower pressure ring 476 and the first adjusting rod 42. When the guide seat 473 moves downward, the downward pressure spring 477 is compressed by the lower pressure ring 476, that is, the first adjusting rod 42 is pushed downward, so that the soil-turning blade 452 can have a downward force, thereby ensuring that the soil-turning blade 452 can turn the soil.

[0054] An ear seat 478 is provided on the side of the guide seat 473 facing away from the worm gear 472, and a guide rod 479 is provided on the ear seat 478. A longitudinally extending guide frame 4710 is provided at the position of the swing arm 21 corresponding to the guide seat 473, and the guide frame 4710 is slidably set in the ear seat 478. A guide hole 4711 for the guide rod 479 to slide is opened in the middle of the guide frame 4710. The mutual cooperation between the guide rod 479 and the guide hole 4711 limits the rotation of the downward pressure assembly 47 to ensure that the downward pressure is smoothly applied to the first adjustment rod 42.

[0055] In the specific implementation process, when turning the soil, the worm 474 is rotated by rotating the rotating rod 475, so that the worm wheel 472 meshing with the worm 474 rotates, and the worm wheel 472 drives the adjusting sleeve 471 to move downward under the cooperation with the thread of the adjusting sleeve 471, and drives the guide seat 473 and the lower pressure ring 476 to move downward, thereby compressing the downward pressure spring 477, giving the soil turning blade 452 a downward force to break the soil, and helping the soil turning assembly 45 to break the soil. When the soil turning is completed, the rotating rod 475 is rotated in the opposite direction, so that the worm 474 rotates in the opposite direction, and the worm wheel 472 meshing with the worm 474 rotates in the opposite direction, and the worm wheel 472 moves upward under the cooperation of the thread of the adjusting sleeve 471, releasing the elastic force of the downward pressure spring 477, so that the soil turning blade 452 is easily pulled out of the soil.

The rotating shaft two 628 is installed in the cavity of the mobile vehicle 1 and rotates corresponding to the rotating shaft one 626. The telescopic rod two 629 is connected between the rotating shaft two 628 and the rotating shaft one 626 through the universal joint 617. The cooperation between the universal joint 617 and the telescopic rod one 618 enables the swing arm 21 to rotate during the swinging process. Even if the relative positions of rotating shaft 1 626 and rotating shaft 2 628 change during the process, power can still be transmitted. Gear 3 6210 is installed on rotating shaft 2 628. Main shaft 2 6211 is horizontally arranged in the cavity of mobile vehicle 1. Two gears 4 6212 are installed on main shaft 2 6211, and gear 4 6212 is meshed with gear 3 6210.

A transverse tube 75 is installed at the end through a bracket, and the transverse tube 75 adjacent to the mounting tube 73 is connected to the mounting tube 73. The two adjacent transverse tubes 75 are connected in a detachable manner, so that fertilizer water can flow smoothly into the transverse tubes 75 to ensure that the fertilizer water can be transported to all transverse tubes 75. The transverse tube 75 is downwardly connected with a guide tube 76, and the lower end of the guide tube 76 is inserted into the rotating column 41. The fertilizer water in the transverse tube 75 smoothly enters the rotating column 41 through the guide tube 76 and then enters the liquid outlet pipe 44 after passing through the first adjusting rod 42 and the second adjusting rod 43. It should be noted that the rotating column 41 and the first adjusting rod 42 and the second adjusting rod 43 are all sealed to prevent overflow of fertilizer water.

[0061] A liquid outlet hole 77 for drainage is provided at the bottom of the liquid outlet pipe 44, and the fertilizer water is discharged into the soil through the liquid outlet hole 77 so as to fully contact the soil; a plurality of liquid discharge pipes 78 are evenly installed on the circumference of the outer wall of the sliding sleeve 451, and the liquid discharge pipe 78 and the liquid outlet pipe 44 are connected through a guide hose 79, and the fertilizer water in the liquid outlet pipe 44 enters the liquid discharge pipe 78 through the guide hose 79 and is then sprayed onto the soil surface. The angles between the plurality of liquid discharge pipes 78 and the liquid outlet pipe 44 are all different, and the angle between the liquid discharge pipe 78 and the liquid outlet pipe 44 does not exceed 90°, so that the angle at which the fertilizer water is sprayed by the liquid discharge pipe 78 is changed to increase the spraying area.

[0062] In the specific implementation process, by adjusting the control valve 72, the fertilizer water inside the fertilizer box 3 flows out through the vertical pipe 71, passes through the installation pipe 73 and then flows into the horizontal pipe 75 through the telescopic hose 74, then flows into the adjacent horizontal pipe 75 through the installation pipe 73, and then flows downward through the guide pipe 76 connected to the horizontal pipe 75, and finally flows into the bottom of the liquid outlet pipe 44, and is guided to the drain pipe 78 through the liquid outlet hole 77 or the guide hose 79 to be sprayed out.

Then, the first rotating shaft 613 is rotated with the cooperation of the second rotating shaft 615, the two universal joints 617 and the telescopic rod 1 618. That is, the sprocket 3 611 rotates synchronously with the first rotating shaft 613. At the same time, the fixed shaft 83 is rotated under the action of the chain 2 614. The rotation of the sprocket 2 84 drives the sprocket 1 81 to rotate through the chain 1 85. At the same time, the tensioning wheel 863 is also rotated with the first rotating shaft 613. The chain 85 is driven, and the sprocket 81 drives the support shaft 466 to rotate. The rotation of the support shaft 466 drives the rotation of the second connecting rod 463. The rotation of the second connecting rod 463 drives one end of the first connecting rod 462 to rotate in a circle, so that the first connecting rod 462 can swing back and forth, and then drive the sliding sleeve 451 to slide back and forth on the liquid outlet pipe 44, and change the rotating motion state of the support shaft 466 into a linear motion state of the sliding sleeve 451 reciprocating up and down, which helps the expansion and gathering of the soil-turning blade 452, and then the soil-turning blade 452 in the gathered state can be smoothly inserted into the soil.

[0067] (2): Motor 2 6213 is started to drive the two gears 4 6212 on the main shaft 2 6211 to rotate synchronously. The two gears 4 6212 respectively drive the gears 3 6210 meshing therewith to rotate, thereby realizing the synchronous rotation of the rotating shaft 2 628. At the same time, with the cooperation of the telescopic rod 2 629 and the two universal joints 617, the rotation of the rotating shaft 1 626 is realized, and then with the cooperation of the sprocket 4 625 and the chain 3 627, the rotation of the wheel axle 623 is realized, and finally the rotation of the rotating column 41 is realized, providing rotational power for the soil turning component 45.

[0068] (3): By controlling the output shaft of motor three 55 to rotate, the support shaft 53 connected to motor three 55 rotates, causing gear five 54 to mesh and rotate in the opposite direction, driving the fourth connecting rod 52 to rotate, driving one end of the third connecting rod 51 to rotate in a circle, causing the other end of the third connecting rod 51 to swing, causing the swing arm 21 to swing back and forth.

[0069] (4): By adjusting the control valve 72, the fertilizer water inside the fertilizer box 3 flows out through the vertical pipe 71, passes through the installation pipe 73 and then flows into the horizontal pipe 75 through the telescopic hose 74, then flows into the adjacent horizontal pipe 75 through the installation pipe 73, and then flows downward through the guide pipe 76 connected to the horizontal pipe 75, and finally flows into the bottom of the liquid outlet pipe 44, and is discharged to the discharge pipe 78 through the liquid outlet hole 77 or the guide hose 79 to be sprayed out.
