DETAILED DESCRIPTION

[0028] Referring to Figures 1-6 In the embodiment of the present application, a plough layer manure directional carbon supplementing device comprises a mounting seat 1, a T-shaped mounting groove is formed in the top of the mounting seat 1, and a hydraulic cylinder 11 is fixedly installed at the bottom of the mounting seat 1; a fixed plate 2 is fixedly installed at the extending end of the hydraulic cylinder 11, two vertical columns 21 are symmetrically and fixedly arranged at the bottom of the fixed plate 2, and an extending plate 22 is fixedly arranged at the side surface of the fixed plate 2; two symmetrically arranged guide rail plates 3 are respectively fixedly installed on the two vertical columns 21, and a guide groove 31 is formed in the guide rail plate 3; a ditching mechanism 4 is rotatably installed between the two vertical columns 21; a soil cleaning assembly 5 comprises a sliding plate 51, a bulldozing plate 52 and a vibrating mechanism 53, two supporting shafts 511 are fixedly arranged at the two sides of the sliding plate 51, a sliding block 512 is rotatably arranged on the supporting shaft 511, the two sliding blocks 512 are respectively and slidably arranged along the guide grooves 31 in the two guide rail plates 3, the bulldozing plate 52 is in a V shape, two T-shaped sliding rods 521 are fixedly arranged at the back side of the bulldozing plate 52, two sliding holes are formed in the sliding plate 51, the two sliding rods 521 respectively slide through the two sliding holes, a first spring 522 is sleeved on the sliding rod 521, and the two ends of the first spring 522 respectively abut against the bulldozing plate 52 and the sliding plate 51. The vibrating mechanism 53 is fixedly arranged on the bulldozing plate 52.

[0029] In the embodiment, the guide groove 31 is a ring-shaped groove composed of four arc-shaped guide rails, the four arc-shaped guide rails are respectively a first guide rail 311 located at the bottom of the guide rail plate 3, a second guide rail 312 located at the top of the guide rail plate 3 and two third guide rails 313 located at the two sides of the guide rail plate 3 and used for connecting the first guide rail 311 and the second guide rail 312.

[0030] In addition, a plurality of soil discharge openings 314 are formed in the inner side of the guide groove 31, and the two side walls of the guide groove 31 are in an arc shape, so that when part of the soil blocks enter the guide groove 31, they will not stay too much inside the guide groove 31, and the sliding block 512 and the guide groove 31 can be arranged in a clearance fit, that is, the sliding block 512 is not completely fitted with the side wall of the guide groove 31, and when sliding, it is fitted with one side wall of the guide groove 31 and rolls to slide, so that when the guide groove 31 has soil blocks inside, the sliding of the sliding block 512 will not be affected, and the sliding of the sliding block 512 can also extrude the soil blocks from the soil discharge openings 314 or the front side of the guide groove 31, so as to ensure that the sliding block 512 can effectively slide along the guide groove 31.

[0031] In this embodiment, the vibration mechanism 53 includes: a support column 531, which is fixedly installed on the bulldozer plate 52 and has a sliding cavity inside; a push rod 532, which is fixedly installed on the sliding plate 51, and a plurality of push plates 533 are fixedly arranged at intervals on the push rod 532. The push rod 532 and the push plates 533 can slide along the sliding cavity; wherein, two back plates 534 are symmetrically fixedly arranged on the side of the support column 531 near the sliding plate 51, and two deflection grooves are symmetrically opened on the side of the support column 531 near the back plates 534. An L-shaped deflection plate 535 is rotatably arranged in the deflection groove. One end of the deflection plate 535 extends into the sliding cavity, and the other end extends into the bulldozer plate 52. A striking block 536 is fixedly arranged at one end of the deflection plate 535 on the bulldozer plate 52. A second spring 537 is arranged between the deflection plate 535 and the back plate 534.

[0032] It should be noted that there is a gap between the striking block 536 and the bulldozing plate 52, meaning that the deflecting plate 535 can deflect in both directions. A ramp (not shown in the figure) can be provided on the portion of the deflecting plate 535 extending into the sliding cavity, facing the bulldozing plate 52. When the push plate 533 slides inward along the sliding cavity, it pushes the deflecting plate 535 to deflect until it completely disengages from the deflecting plate 535, at which point the deflecting plate 535 returns to its original deflected position. When the push plate 533 slides out of the sliding cavity and returns to its original position, it slides along the ramp while pushing the deflecting plate 535 to deflect, allowing the push plate 533 to slide through without the deflecting plate 535 deflecting too much. Therefore, a gap can be provided between the striking block 536 and the bulldozing plate 52 to allow the deflecting plate 535 to deflect, ensuring that the push plate 533 can slide back to its original position.

[0033] In this embodiment, the trenching mechanism 4 includes a turntable 41, a guide plate 42, and a soil breaking block 43. The turntable 41 is rotatably installed between the two columns 21. Multiple arc-shaped guide plates 42 are uniformly fixed on the turntable 41 along the circumference, and the cross-sectional shape of the guide plate 42 is V-shaped. A V-shaped soil breaking block 43 is fixed at the end of the guide plate 42.

[0034] In implementation, such as Figure 1As shown, when the trenching work is carried out, the rotating disc 41 rotates clockwise, that is, rotates in the direction opposite to the traction direction of the traction mechanism, the soil breaking block 43 and the soil guide plate 42 perform the trenching work from bottom to top, and the soil blocks generated by the trenching can be transported to the ground by the soil guide plate 42 and transported to both sides of the trench, and the soil breaking work and the soil transporting work are always carried out on the side of the trenching mechanism 4 located in the advancing direction of the traction mechanism, thereby avoiding the soil blocks falling into the trench after excavation, and the cooperation of the soil cleaning assembly 5 ensures that the soil breaking block 43 and the soil guide plate 42 do not stick to larger soil blocks when they complete the trenching work and re-enter the trench, further ensuring that the excavated trench can remain unobstructed, providing convenience for subsequent fertilization and carbon application work.

[0035] In addition, the power source for rotating the rotating disc 41 along the stand 21 is an external driving mechanism. A first gear plate can be arranged on the transmission shaft of the rotating disc 41, a driving shaft 7 is arranged to rotate on the fixed plate 2, a second gear plate is arranged on the driving shaft 7, the first gear plate and the second gear plate are drivingly connected by a chain, a chain transmission channel is arranged in the stand 21 to ensure that dust does not enter the transmission system, and a pin hole is arranged in the driving shaft 7, so that the driving shafts 7 of the two adjacent devices are drivingly connected by a pin shaft, and thus one power driving mechanism can drive all the trenching mechanisms 4 to work.

[0036] In the embodiment, the bottom side of the sliding plate 51 and the bulldozing plate 52 is a V-shaped groove with the same cross-sectional shape as the soil guide plate 42, two L-shaped clamping blocks 513 are symmetrically arranged at the bottom of the sliding plate 51, a C-shaped clamping groove is formed between the L-shaped clamping block 513 and the sliding plate 51, the soil guide plate 42 is slidingly arranged along the clamping groove, and two rotating rollers 514 are rotatably arranged on the L-shaped clamping block 513, and the two rotating rollers 514 can roll along the back side of the soil guide plate 42.

[0037] It should be noted that the clamping groove is also in gap sliding cooperation with the soil guide plate 42, that is, there is a gap between the sliding plate 51 and the soil guide plate 42, that is, a small amount of soil blocks can also pass between the sliding plate 51 and the soil guide plate 42, and the L-shaped clamping block 513 limits the placement position of the sliding plate 51 on the soil guide plate 42, ensures that the sliding plate 51 can push the bulldozing plate 52 along the soil guide plate 42, and is less affected by the soil blocks during the sliding process, and does not appear to be stuck.

[0038] It needs to be explained that the purpose of the bulldozing plate 52 is not to completely clean the soil on the guide plate 42, that is, not to slide on the surface of the guide plate 42, but to clean most of the soil on the guide plate 42, to ensure that the guide plate 42 can maintain a good soil conveying effect as much as possible, and correspondingly, the cleaning of the broken soil block 43 is similar to the cleaning effect of the guide plate 42, that is, not to clean the soil, but to prevent the accumulation of the soil block from causing the broken soil block 43 and the guide plate 42 to be unable to work.

[0039] In the embodiment, a sliding column 23 is slidably arranged on each of the two columns 21, a first hydraulic telescopic rod is arranged between the sliding column 23 and the fixed plate 2, and a depth limiting wheel 24 is rotatably arranged at the end of the sliding column 23.

[0040] In the embodiment, an L-shaped support plate 25 is fixedly arranged on each of the two sliding columns 23, the two L-shaped support plates 25 are arranged in parallel, and the two L-shaped support plates 25 are symmetrically and obliquely arranged at the bottom of the two L-shaped support plates 25. Two soil covering plates 26 are arranged in a V-shaped manner.

[0041] In the embodiment, two mounting holes are formed in the extension plate 22, two material application pipes 6 are fixedly installed in the two mounting holes respectively, a first sleeve pipe 61 and a second sleeve pipe 62 are sequentially sleeved on the bottom of the two material application pipes 6 along the extension direction of the extension plate 22, a plurality of second hydraulic telescopic rods are arranged between the first sleeve pipe 61 and the second sleeve pipe 62 and the extension plate 22 respectively, and a V-shaped soil retaining plate 63 is fixedly arranged on the first sleeve pipe 61.

[0042] Specifically, the V-shaped soil retaining plate 63 arranged on the first sleeve pipe 61 for applying fertilizer can further prevent the soil in the trench from adhering to the first sleeve pipe 61, thereby ensuring that the first sleeve pipe 61 will not be blocked, and at the same time, the soil retaining plate 63 can separate the excavated trench to a certain extent, prevent the manure from flowing to the front side of the first sleeve pipe 61 when the manure is applied, and thereby can strictly control the application height of the manure, that is, the application amount of the manure, to ensure that the manure layer and the carbon material layer at the same height position maintain a good proportion, so that the carbon supplement effect is better.

[0043] A method for applying manure to a plough layer and supplementing carbon in a targeted manner, comprising the following steps:

[0044] S1, the mounting seat 1 is installed on a traction mechanism, the operation height of the entire device is adjusted by driving the hydraulic cylinder 11 to act according to the manure application requirement, the height of the depth limiting wheel 24 and the soil covering plate 26 is adjusted by the first hydraulic telescopic rod, and the trenching depth and the soil covering effect are set;

[0045] Specifically, the entire device can be regarded as a whole module, and a suitable number of modules can be selected according to the specific fertilization needs, and they are installed on the traction mechanism in intervals, wherein the traction mechanism can be a tractor or other power traction equipment, and for the installation of the mounting seat 1, a beam structure can be provided on the traction mechanism, and the mounting seat 1 is slidably installed on the beam by means of the installation slot provided on the mounting seat 1, and the spacing between the devices can be adjusted after installation, and the mounting seat 1 is locked on the beam by means of the bayonet or the hydraulic cylinder 11;

[0046] S2, the whole device is pulled forward by the traction mechanism, and the trenching mechanism 4 is driven to rotate to dig a trench, and the rotation of the trenching mechanism 4 can drive the soil cleaning assembly 5 to slide along the guide groove 31, so that the soil cleaning assembly 5 reciprocally slides along the soil guide plate 42 to clean the soil on the soil guide plate 42;

[0047] Specifically, the soil cleaning assembly 5 will slide along with the rotation of the trenching mechanism 4, so that the sliding blocks 512 on both sides of the sliding plate 51 slide along the guide groove 31, that is, along the first guide rail 311, the second guide rail 312 and the third guide rail 313, wherein when the sliding block 512 slides on the first guide rail 311, the soil cleaning assembly 5 is located at the root of the soil guide plate 42, and the relative position between the soil cleaning assembly 5 and the soil guide plate 42 does not change, when the sliding block 512 slides from the first guide rail 311 to the third guide rail 313, the soil cleaning assembly 5 will slide along the soil guide plate 42, thereby pushing the bulldozing plate 52 to slide to clean the soil on the soil guide plate 42, and when the sliding block 512 does not slide from the third guide rail 313 to the second guide rail 312, the sliding plate 51 will drive the bulldozing plate 52 to slide and abut on the broken soil block 43, and along with the sliding of the sliding block 512 along the third guide rail 313, the sliding plate 51 will continue to slide, thereby making the sliding rod 521 slide through the sliding hole and compress the first spring 522, in this process, the vibration mechanism 53 will act to produce vibration, so that the soil on the bulldozing plate 52 and the soil on the broken soil block 43 are shaken off, when the sliding block 512 slides from the third guide rail 313 to the second guide rail 312, the sliding plate 51 will reset and slide away from the bulldozing plate 52 at this time, so that the first spring 522 resets, and then when the sliding block 512 slides from the second guide rail 312 to another third guide rail 313, along with the sliding of the sliding block 512, the soil cleaning assembly 5 will slide to the root of the soil guide plate 42 again, and then the sliding block 512 continues to slide to the first guide rail 311, and the cycle is repeated, so that the soil cleaning assembly 5 can reciprocally slide along the soil guide plate 42 and clean the soil on the soil guide plate 42 and the broken soil block 43, thereby ensuring that the trenching mechanism 4 can always maintain good trenching efficiency;

[0048] S3, when the soil cleaning assembly 5 slides to the end of the soil guide plate 42 and contacts the soil breaking block 43, the sliding plate 51 continues to slide, so that the push rod 532 and the push plate 533 slide into the sliding cavity and push the deflection plate 535 to deflect, and when the push plate 533 is separated from the deflection plate 535, the second spring 537 drives the deflection plate 535 to knock on the bulldozing plate 52, so that the bulldozing plate 52 vibrates and transmits the vibration to the soil breaking block 43 and the soil guide plate 42;

[0049] Specifically, when the sliding plate 51 slides so that the sliding rod 521 passes through the sliding hole and extrudes the first spring 522, at this time the push rod 532 will slide into the sliding cavity, and because the push plate 533 is arranged on the push rod 532, the push plate 533 will contact the deflection plate 535 extending into the sliding cavity. And push the deflection plate 535 to deflect, and in the deflection process, the deflection plate 535 will extrude the second spring 537 to store energy, and then after the push plate 533 is separated from the deflection plate 535, the second spring 537 will instantaneously drive the deflection plate 535 to reset and make the knocking block 536 hit on the bulldozing plate 52, so that the bulldozing plate 52 vibrates and shakes the soil on its surface. At the same time, because the bulldozing plate 52 is in contact with the soil breaking block 43, the vibration force is transmitted to the soil breaking block 43 and the soil guide plate 42, so that the soil breaking block 43 and the soil guide plate 42 also vibrate, thereby further shaking the soil on the soil breaking block 43 and the soil guide plate 42, that is, effectively improving the soil cleaning effect of the soil cleaning assembly 5, and further ensuring that the soil breaking block 43 and the soil guide plate 42 have good ditching effect;

[0050] S4, by arranging the first sleeve 61 and the second sleeve 62 in front and back, the two fertilizer application pipes 6 with adjustable height are sleeved, the manure is applied to the bottom of the ditch through the fertilizer application pipe 6 connected with the first sleeve 61, and the carbon material is applied above the manure layer through the other fertilizer application pipe 6, so that a layered structure of lower manure and upper carbon is formed in the ditch.

[0051] This directional layered application technology directly creates an ideal microenvironment in the soil, in which the manure and the carbon material are closely adjacent, greatly promotes the activity efficiency of microorganisms, effectively reduces the nitrogen volatilization and leaching, improves the nutrient utilization rate, and significantly enhances the carbon sequestration capacity of the soil.

[0052] S5, the soil excavated is filled back into the ditch by the two V-shaped soil covering plates 26, covering the manure and the carbon material, and the directional carbon supplementing operation is completed.

[0053] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
