Description

Technical Field

[0001] The present invention relates to the technical field of soil turning and restoration, and in particular to a soil restoration device and method for facilitating soil screening. Background Art

[0002] In actual soil management and restoration work, in addition to using chemicals for sterilization and other operations, soil restoration work also requires soil turning. By turning the soil, the soil structure can be improved, soil permeability can be increased, root growth can be promoted, and crop yield can be increased. In the process of turning the soil, it is necessary to screen and separate the ground film and stone impurities. Traditional soil turning and restoration mainly turns the soil by plowing or rotary tilling with a rotary tiller. It is widely used due to its flexible use and other advantages. The current soil restoration device that is easy to screen the soil is mostly mixed with the topsoil when the plow bottom layer is actually turned over, resulting in the soil layer after turning over being mixed with the topsoil, which is not convenient for directly turning over and replacing the soil, and the turning over is not thorough enough. At the same time, it is also not convenient to control the turning over position. The turning over position control accuracy is poor, and the core layer soil below the plow bottom layer is easily turned out, which will affect the soil turning quality and turn over the soil layer with less nutrients. The screening rake teeth are easily entangled with stones and ground film, which is not convenient for automatic cleaning. Summary of the invention

The rectangular structure of the rotary turning portion 2 is utilized to move through the soil layer, and the soil layer can be directly rotated 180 degrees after being inserted into the internal part, so as to realize the control of soil turning, which can prevent the topsoil from mixing with the bottom soil of the plow, and ensure thorough soil turning. This structure can reduce the frequency of soil turning, improve the quality of soil turning, and ensure that the soil nutrients after soil turning are sufficient by directly rotating the soil layer. At the same time, this structure directly turns the weeds on the topsoil and covers them underground, which also plays a role in weeding, avoiding the problem of weed roots easily growing again in the rotary tillage method of traditional rotary tillers.

[0024] In the disclosed embodiment, the distance control unit 3 includes: a control wheel 301 and an extrusion spring piece 302, and the control wheels 301 are rotatably installed on both sides of the docking frame 103; a circle of raised columns are respectively provided on the outer sides of the two control wheels 301; an extrusion spring piece 302 is fixedly installed on the inner side of the control wheel 301 close to the rotary micro switch 104, and the extrusion spring piece 302 is installed obliquely; the extrusion spring piece 302 is an elastic steel sheet structure; the end of the extrusion spring piece 302 is used to squeeze the rotary micro switch 104; the distance control unit 3 can be used to control the rotary control motor 203 to perform rotational driving work, which can ensure that the soil layer can automatically perform flipping control work as the structure is towed and moved by the tractor, and at the same time, the distance control unit 3 can play a role in distance measurement to ensure that the structure is not affected by the running speed of the tractor, and can ensure The topsoil in the rotating cylinder 201 can be rotated and replaced in sequence. The structure is simple and the operation is stable. The soil turning effect can also be guaranteed for the sandy soil layer. The rotating cylinder 201 is used to surround the soil layer. The control wheel 301 is attached to the soil and driven by the friction of the soil to rotate. As the control wheel 301 rotates one circle, it can drive the squeezing spring 302 to squeeze the rotary microswitch 104. The controller of the rotary control motor 203 controls the rotary control motor 203 to rotate one hundred and eighty degrees. At this time, the soil layer inside the rotating cylinder 201 is turned over. As the rotating cylinder 201 continues to move, the new soil layer can push out the turned soil layer. In this way, the control wheel 301 rotates one more circle. At this time, the rotating cylinder 201 can be turned over again to continue the soil turning work. The structure is simple to control and mature.

[0025] In the disclosed embodiment, the soil turning and jointing control member 4 includes: a detection connection tube 401, an anti-misconducting spring 402, a sensitive adjustment stud 403, a hard soil squeezing column 404 and a jointing micro switch 405. The detection connection tube 401 is fixedly installed at the bottom of the soil taking tube 101; the detection connection tube 401 is internally sleeved with an anti-misconducting spring 402; the detection connection tube 401 is threadedly connected with a sensitive adjustment stud 403; the detection connection tube 401 is slidably sleeved with a hard soil squeezing column 404, and the front end of the hard soil squeezing column 404 is a cone The hard soil squeezing column 404 is fixedly connected to the anti-mistouch spring 402 at the tail end; the joint micro switch 405 is fixedly installed on the inner side of the hard soil squeezing column 404; the joint micro switch 405 is aligned with the sensitive adjustment stud 403; the hard soil squeezing column 404 is vertically aligned with the side edge of the soil taking barrel 101; the joint micro switch 405 is electrically connected to the prompt light 105 on the same side; the use of the soil turning joint control part 4 can facilitate the staff to understand the current soil turning position accuracy, can improve the soil turning accuracy, and avoid the adjacent soil that has been turned over The soil is turned over again, causing the topsoil to be turned out again. The present structure uses the joint micro switch 405 to detect the harder soil layer, and uses the looseness of the soil layer after turning over to improve the quality of turning over. In particular, for the turning over of sandy soil, the soil layer is prone to collapse, and it is inconvenient to observe with the naked eye. The sensitive adjustment stud 403 used can adjust the position, that is, the sensitivity. The closer the sensitive adjustment stud 403 is to the joint micro switch 405, the easier it is for the sensitive adjustment stud 403 to compress the anti-mistouch spring 402 and squeeze it. The sensitive adjustment stud 403 is simple and flexible to operate. After the soil barrel 101 is inserted into the soil, the hard soil squeezing column 404 is located on the side of the adjacent turned soil layer. If the hard soil squeezing column 404 is not pressed on the unturned soil layer, but is located on the turned soil layer, the soil layer is soft at this time. As the soil barrel 101 moves, it is difficult to squeeze the hard soil squeezing column 404 because of the soft soil layer, and the anti-mistouch spring 402 is compressed. At this time, the connection micro switch 405 will not be squeezed, and the prompt light 105 will not light up to prompt.

[0026] In the disclosed embodiment, the plow bottom layer detection member 5 includes: a plow bottom layer detection installation tube 501, a compression shaft 502, a buffer spring 503 and a retraction pressure block 5031. The plow bottom layer detection installation tube 501 is fixedly installed at the bottom of the soil taking tube 101; the compression shaft 502 is slidably inserted on the plow bottom layer detection installation tube 501, and the front end of the compression shaft 502 is an inclined structure; the plow bottom layer detection installation tube 501 is sleeved with a buffer spring 503, and the end of the buffer spring 503 is connected to the compression shaft 502; the retraction pressure block 5031 is slidably installed on the soil taking tube 101. The plow bottom detection member 5 also includes: a pressure sensor 504 and a retracting spring 505, which can be a HZC-H1 type pressure sensor 504, and a matching display, the pressure sensor 504 is fixedly mounted on the retracting pressure block 5031; the end of the pressure sensor 504 is attached to the inside of the soil barrel 101; the pressure sensor 504 is externally connected to a display; the retracting spring 505 is fixedly mounted on the compression shaft 502 by bolts; the retracting spring 505 is an elastic steel sheet structure; the end of the retracting spring 505 is plugged into the retracting pressure block 5031. The front end of the block 5031; the pressure sensor 504 is used to detect the plow bottom layer. The plow bottom layer detection member 5 can be used to detect the hardness of the soil layer when the structure is turned over, so as to avoid the problem that the thickness of the plow bottom layer at different positions is not completely uniform, and the soil is easily turned over too deep, resulting in the problem of turning out a harder core layer of soil. The structure can ensure the quality of turning over, and intuitively display the hardness of the underground soil layer through digital display, which is convenient for the staff to make timely adjustments. It is more practical and has a simple structure. At the same time, the retractable spring piece 505 uses its elastic steel sheet structure to facilitate replacement, avoid squeezing and damaging the pressure sensor 504, and has low cost. The compression shaft 502 will drive the retractable spring piece 505 to squeeze the retractable pressure block 5031 under the squeezing of the soil layer. The current soil hardness can be detected by squeezing the pressure sensor 504 through the retractable pressure block 5031. If the hardness is too high, the turning over depth needs to be adjusted in time. If the hardness is high, the elastic structure of the retractable spring piece 505 can be bent or broken, and the bolts on the retractable spring piece 505 can be disassembled and replaced later. The buffer spring 503 can be used to squeeze the compression shaft 502 to reset.

[0027] Embodiment 2, on the basis of embodiment 1, the screening auxiliary part 6 comprises: a screening connection frame 601, a rake rod 602 and rake teeth 603, the screening connection frame 601 is fixedly mounted on the docking frame 103; the rake rod 602 is fixedly mounted on the screening connection frame 601, and a row of rake teeth 603 is fixedly mounted at the bottom of the rake rod 602; the automatic cleaning part 7 comprises: a sliding shaft 701, a cleaning tension spring 702 and a cleaning scraping rod 703, the sliding shaft 701 is provided with two, and the two sliding shafts 701 are respectively slidably mounted at both ends of the rake rod 602; the two sliding shafts 701 are respectively sleeved with cleaning tension springs 702, and the ends of the two cleaning tension springs 702 are respectively connected to the two ends of the rake rod 602, and the other ends of the two cleaning tension springs 702 are respectively connected to the ends of the two sliding shafts 701; the bottoms of the two sliding shafts 701 A cleaning scraping rod 703 is fixedly installed on the top; the cleaning scraping rod 703 is slidably sleeved on a row of rake teeth 603; the cleaning scraping rod 703 is used to clean a row of rake teeth 603. The screening auxiliary part 6 can be used to facilitate the screening of gravel impurities, ground film, etc. in the soil, which can improve the soil quality after turning the soil. At the same time, the row of rake teeth 603 also plays a role in eliminating soil clods and garbage, which is convenient for loosening the soil. The automatic cleaning part 7 can realize automatic cleaning and scraping of the rake teeth 603. The cleaning scraping rod 703 that can be elastically lifted and lowered is used. During the tractor turning around, the height of the soil taking barrel 101 needs to be raised. At this time, the cleaning scraping rod 703 loses soil extrusion, and the cleaning scraping rod 703 can be pulled down by the cleaning tension spring 702 to discharge garbage or stones such as ground film on the rake teeth 603.

[0028] A soil remediation method that facilitates soil screening: 1) The docking frame 103 is used to be installed on the tractor using an axle pin. The soil taking barrel 101 is driven to move by the tractor. The friction of the soil drives the control wheel 301 to rotate. The control wheel 301 rotates one circle, driving the squeezing spring 302 to squeeze the rotary micro switch 104. The controller of the rotary control motor 203 controls the rotary control motor 203 to rotate 180 degrees, and the soil layer inside the rotating barrel 201 is turned over and discharged; 2) After the rake teeth 603 are inserted into the soil, large stones and garbage in the soil are screened out. Under the pressure of the soil, the cleaning scraping rod 703 will drive the sliding shaft 701 to rise and fit the surface of the soil layer without blocking the rake teeth 603. Under the pulling of the cleaning tension spring 702, the cleaning scraping rod 703 moves down to scrape the plastic film garbage on the rake teeth 603.

[0029] The working principle of this embodiment is as follows: first, the universal connecting frame of the tractor is docked through the three pin holes on the docking frame 103, and the connecting frame of the existing tractor is used to control the soil barrel 101 to fall and insert into the soil. The inner top of the soil barrel 101 sticks to the surface of the soil layer and moves, and the soil barrel 101 will be inserted into the soil. As the soil barrel 101 continues to move, the rotating cylinder 201 will also be inserted into the soil. At the same time, the control wheel 301 will also stick to the soil and be driven by the friction of the soil to rotate. As the control wheel 301 rotates one circle, it can drive the squeezing spring piece 302 to squeeze the rotary microswitch 104, and the controller of the rotary control motor 203 controls the rotary control motor 203 to rotate one hundred and eighty degrees. At this time, the soil layer inside the rotating cylinder 201 is turned over. As the rotating cylinder 201 continues to move, the newly entered soil layer can push out the turned soil layer. In this way, the control wheel 301 can be controlled again. After rotating one circle, the rotating cylinder 201 can be turned over again to continue the soil turning work; when the soil taking cylinder 101 moves underground, it can drive the compression shaft 502 to move at the same time. Under the pressure of the soil layer, the compression shaft 502 will drive the retraction spring 505 to squeeze the retraction pressure block 5031. By squeezing the retraction pressure block 5031, the pressure sensor 504 can be detected to detect the current soil hardness; after the rake teeth 603 are inserted into the soil, the cleaning scraper rod 703 will drive the sliding shaft 701 to rise under the pressure of the soil to avoid blocking the rake teeth 603. By using the elastic traction of the cleaning tension spring 702, after completing a trip of soil turning work, the height of the soil taking cylinder 101 needs to be raised during the U-turn process of the tractor to avoid jamming. At this time, the cleaning scraper rod 703 loses the soil extrusion, and the cleaning scraper rod 703 can be pulled down by the cleaning tension spring 702 to push and discharge the garbage or stones such as the ground film on the rake teeth 603; After the soil-taking barrel 101 is inserted into the soil, the hard soil squeezing column 404 corresponding to the side of the adjacent turned soil layer, if the hard soil squeezing column 404 is not pressed on the edge of the unturned soil layer, but is located at the turned soil layer, the soil layer is soft at this time. As the soil-taking barrel 101 moves, it is difficult to squeeze the hard soil squeezing column 404 because the soil layer is soft and compresses the anti-mistouch spring 402. At this time, the micro switch 405 will not be squeezed, and the warning light 105 will not light up to remind, so the staff can be informed in time and adjust The position of the soil-taking barrel 101 ensures that the soil layer to be turned has not been turned before. The staff observes the position of the soil-taking barrel 101 in real time and tries to make its edge close to the cross-section of the soil layer that has not been turned. At this time, as the soil-taking barrel 101 moves, the soil layer that has not been turned will be relatively compact, which will squeeze the hard soil squeezing column 404, compress the anti-mistouch spring 402, and drive the joint microswitch 405 to touch the sensitive adjustment stud 403, so that the prompt light 105 lights up to prompt, so as to more intuitively understand the landing point of the lower edge of the soil-taking barrel 101.
