Description

Technical Field

[0001] This invention relates to the field of land preparation equipment technology, and in particular to a land preparation equipment for ecological landscaping projects. Background Technology

[0002] Ecological landscaping engineering prioritizes ecology and combines elements such as plants, topography, water bodies, soil, and landscape to design, construct, and maintain sustainable and self-regulating urban / regional green space systems. Land preparation is the basic procedure in ecological landscaping engineering, which can improve soil structure, enhance soil quality, and create suitable terrain.

[0003] Before the land preparation begins, in order to avoid the grass roots and residual straw in the soil from affecting the land preparation effect, a disc rake is usually used to rake the grass roots out of the ground first. Then the grass roots and straw are collected and crushed. The crushed grass roots and straw are then returned directly to the field, as disclosed in the invention patent with authorization announcement number CN119213915B.

[0004] However, when the above-mentioned scheme and similar schemes in the prior art carry out the grass root return operation during the land preparation process, the crushed grass roots can only fall on the surface of the soil after rotary tillage and cannot be buried deep in the soil. The decomposition speed is extremely slow. Since grass roots are high in carbon and low in nitrogen, nitrogen competition will occur during the decomposition process. Therefore, if sowing / transplanting is carried out before the grass roots are completely decomposed, it is very easy to cause poor crop growth.

[0005] Therefore, it is necessary to invent an ecological land preparation device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an ecological landscaping engineering landscaping device. By pushing a column to compress and output the mixture, it avoids blockage and allows the mixture to be buried deep in the soil, thereby effectively increasing the speed at which grass roots decompose into organic fertilizer. In addition, the addition of urea can compensate for the nitrogen consumed during grass root decomposition, further increasing the decomposition speed while preventing grass roots from competing for nitrogen during decomposition, which would lead to poor crop growth. This solves the problem mentioned in the background art, where crushed grass roots can only fall on the surface of the soil after rotary tillage and cannot be buried deep in the soil, resulting in a very slow decomposition speed. Because grass roots are high in carbon and low in nitrogen, nitrogen competition occurs during decomposition. Therefore, if sowing / transplanting is carried out before the grass roots are fully decomposed, it is very easy to cause poor crop growth.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an ecological landscaping engineering landscaping device, comprising a connecting frame, a grass root turning-out component disposed at the bottom left end of the connecting frame, a grass root crushing component disposed at the bottom right end of the connecting frame, a soil rotary tillage component disposed at the bottom right side of the grass root crushing component, a nitrogen fertilizer addition component disposed inside the grass root crushing component, and a mixture deep burial component disposed at the bottom right side of the grass root crushing component. The mixture deep burial component includes a sealing plate fixedly disposed at the bottom right side of a U-shaped mounting frame, and a motor D fixedly disposed at the top right side of the sealing plate. The output shaft of the motor D extends to the left side of the sealing plate. A rotating disk is fixedly connected to the side. A drive slide rod is nested on the bottom left side of the rotating disk via a bearing. The mixture deep-buried assembly also includes two guide shafts fixedly installed on the right side of the inner side of the U-shaped mounting frame. A lifting frame is slidably sleeved on the outer side of the two guide shafts in the vertical direction via linear bearings. A drive groove adapted to the drive slide rod is opened in the middle of the side of the lifting frame. The drive slide rod is slidably installed inside the drive groove. Multiple push columns are evenly fixedly installed at the bottom of the drive groove, each located directly above an adjacent rotating cylinder. Racks adapted to adjacent gears are fixedly connected to both ends of the left side of the lifting frame.

[0008] Preferably, the grass root turning component includes two side plates fixedly disposed on the left side of the bottom of the connecting frame. An inclined rotating shaft A is rotatably nested between the two side plates via a ball bearing. Multiple disc rakes are uniformly fixedly sleeved on the outside of the rotating shaft A. A motor A, which is drively connected to the rotating shaft A, is fixedly disposed on the outside of any one of the side plates.

[0009] Preferably, the grass root crushing component includes a U-shaped mounting bracket fixedly disposed on the bottom right side of the connecting frame, wherein a guide slope is provided on the left side inside the U-shaped mounting bracket, and multiple mounting holes are provided on the right side inside the U-shaped mounting bracket.

[0010] Preferably, a crushing cylinder is fixedly installed on the left side inside the U-shaped mounting frame, located above the guide slope. A grass root inlet is opened at the top left side of the crushing cylinder. An inclined screen plate is fixedly installed on the left side of the crushing cylinder, located on the side of the grass root inlet and inclined. An arc-shaped screen is fixedly nested at the bottom of the crushing cylinder.

[0011] Preferably, a crushing blade is provided inside the crushing cylinder, and the crushing blade is rotatably nested inside the U-shaped mounting frame via a ball bearing. A motor B, which is connected to the crushing blade, is fixedly installed on the front of the U-shaped mounting frame.

[0012] Preferably, the soil rotary tillage assembly includes multiple buried cylinders fixedly installed inside adjacent mounting holes. The bottom right side of each buried cylinder has a mixture outlet connected to the bottom opening of the buried cylinder. A rotating cylinder is rotatably sleeved on the outside of any one of the buried cylinders via a ball bearing. A driven wheel is fixedly sleeved on the top of the outer side of the rotating cylinder. Multiple evenly distributed rotary tillage plates are fixedly installed on the middle and bottom of the outer side of the rotating cylinder.

[0013] Preferably, the soil rotary tillage assembly further includes a fixing plate fixedly disposed on the right side of the front of the U-shaped mounting frame. A motor C is fixedly disposed on the top of the fixing plate. The output shaft of the motor C extends to the bottom of the fixing plate and is fixedly connected to a drive wheel. A synchronous belt is sleeved on the outside of the drive wheel and multiple driven wheels for common transmission.

[0014] Preferably, the nitrogen fertilizer addition component includes a storage hopper fixedly mounted on the top of the connecting frame and extending into the inner side of the U-shaped mounting frame. A rotating shaft B is rotatably nested at the bottom of the inner cavity of the storage hopper via a ball bearing. Gears are rotatably sleeved at both ends of the outer side of the rotating shaft B via one-way bearings.

[0015] Preferably, a feeding roller that blocks the bottom opening of the storage hopper is fixedly sleeved on the outer middle of the rotating shaft B, and multiple storage troughs are evenly opened on the outer side of the feeding roller.

[0016] The technical effects and advantages of this invention are as follows:

[0017] This invention incorporates a deep-burying component for the mixture. After the grass roots are crushed, they are evenly mixed with nitrogen fertilizer and fed into the deep-burying cylinder. The mixture is then extruded by a pushing column, preventing blockages and ensuring the mixture is buried deep in the soil. This effectively increases the rate at which the grass roots decompose into organic fertilizer. Furthermore, the addition of urea compensates for the nitrogen consumed during the decomposition of the grass roots, further increasing the decomposition rate while preventing the grass roots from competing for nitrogen during decomposition, which could lead to poor crop growth.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides, for example Figures 1-6 The above-described ecological landscaping engineering land preparation device includes a connecting frame 1 welded from Q355B low alloy high strength structural steel. A grass root turning component 2 is provided at the bottom left end of the connecting frame 1, a grass root crushing component 3 is provided at the bottom right end of the connecting frame 1, a soil rotary tillage component 4 is provided at the bottom right side of the grass root crushing component 3, a nitrogen fertilizer addition component 5 is provided inside the grass root crushing component 3, and a mixture deep burial component 6 is provided at the bottom right side of the grass root crushing component 3.

[0027] like Figure 2As shown, the grass root turning component 2 includes two side plates 21 fixedly installed on the bottom left side of the connecting frame 1. The side plates are made of Q235B carbon structural steel with powder coating for corrosion protection. An inclined rotating shaft A22 is nested between the two side plates 21 via a ball bearing. Multiple disc rakes 23 are uniformly fixedly sleeved on the outside of the rotating shaft A22. The disc rakes 23 are made of 65Mn spring steel, with overall quenching and tempering treatment. The cutting edge is boronized to strengthen it, giving it both toughness and wear resistance. After boronizing, the resistance to soil abrasion and sand and gravel impact is greatly improved, making it less prone to chipping or breaking when turning over grass roots, thus reducing the frequency of replacing vulnerable parts. A motor A24 is fixedly installed on the outside of any side plate 21 and is connected to the rotating shaft A22 for transmission.

[0028] By setting up the above structure, the motor A24 drives multiple disc rakes 23 to rotate continuously counterclockwise through the rotating shaft A22, thereby turning over the grass roots in the soil. At the same time, the turned-over grass roots are thrown towards the inclined screen plate 36 by the centrifugal force generated when the disc rakes 23 rotate.

[0029] like Figure 3 As shown, the grass root crushing component 3 includes a U-shaped mounting bracket 31 fixedly installed on the bottom right side of the connecting frame 1. The bracket is also made of Q355B low-alloy high-strength steel, with anti-corrosion coating on both the inner and outer surfaces. A guide slope 32 is provided on the left side inside the U-shaped mounting bracket 31, and multiple mounting holes 33 are provided on the right side inside the U-shaped mounting bracket 31. A crushing cylinder 34, made of ZG270-500 cast steel, is fixedly installed on the left side inside the U-shaped mounting bracket 31, located above the guide slope 32. The inner wall of the crushing cylinder 34 is treated with wear-resistant alloy welding. A grass root inlet 35 is provided on the top left side of the crushing cylinder 34. An inclined screen plate 36 is fixedly installed on the left side of the crushing cylinder 34, located on one side of the grass root inlet 35 and angled. An arc-shaped screen 37 is fixedly nested at the bottom of the crushing cylinder 34, along with the inclined screen plate. All parts 36 are made of 304 stainless steel, which has excellent corrosion and rust resistance. It can be in contact with nitrogen fertilizer and moist soil for a long time without mesh blockage, rust and damage. The crushing cylinder 34 is equipped with crushing blades 38, which are made of 9CrSi alloy tool steel. They are quenched and tempered at low temperature. The blade edge is coated with a laser-coated wear-resistant coating, which has excellent wear resistance and impact resistance. The laser-coated coating can resist the erosion and wear of sand and gravel carried by grass roots. The blade edge has good sharpness retention and can achieve ultra-fine crushing of grass roots to ensure subsequent composting efficiency. At the same time, it is not easy to have grass entanglement and material blockage problems. The crushing blades 38 are rotatably nested in the U-shaped mounting bracket 31 through ball bearings. The motor B39, which is connected to the crushing blades 38, is fixed on the front of the U-shaped mounting bracket 31.

[0030] By setting up the above structure, grass roots are thrown towards the inclined screen plate 36 and fall to the top of the inclined screen plate 36 and slide along the inclined screen plate 36. During this process, the soil that is also thrown passes through the inclined screen plate 36 and falls down, while the grass roots enter the crushing cylinder 34 through the grass root inlet 35. Then, the motor B39 drives the crushing blade 38 to rotate continuously inside the crushing cylinder 34, thereby crushing the grass roots that have entered the crushing cylinder 34. After crushing, the qualified grass roots pass through the arc screen 37 and fall to the top of the guide slope 32. Then, under the guidance of the guide slope 32, they continue to slide towards the top opening of the deep burial cylinder 41.

[0031] like Figure 4 As shown, the soil rotary tillage assembly 4 includes multiple buried cylinders 41 fixedly installed inside adjacent mounting holes 33. These cylinders are made of seamless steel pipes with hard chrome plating on the inner wall and hardened ends. A mixture outlet 42, connected to the bottom opening of the bottom of the buried cylinder 41, is located on the right side of each buried cylinder 41. A rotating cylinder 43, made of low-alloy high-strength steel, is rotatably sleeved on the outside of any buried cylinder 41 via a ball bearing. A driven wheel 44 is fixedly sleeved on the top of the outer side of the rotating cylinder 43. Multiple evenly distributed rotary tillage plates 45 are fixedly installed on the middle and bottom of the outer side of the rotating cylinder 43, with their working surfaces made of wear-resistant alloy. The soil is welded, providing excellent resistance to soil abrasion and stone impact. It can achieve deep rotary tillage, providing a suitable loose soil environment for deep burial of mixtures. After rotary tillage, the soil looseness is uniform, directly adapting to the needs of garden planting. The soil rotary tillage component 4 also includes a fixing plate 46 fixedly installed on the right side of the front of the U-shaped mounting frame 31. The plate is made of Q235B steel with hot-dip galvanized surface treatment. A motor C47 is fixedly installed on the top of the fixing plate 46. The output shaft of the motor C47 extends to the bottom of the fixing plate 46 and is fixedly connected to the drive wheel 48. The drive wheel 48 and multiple driven wheels 44 are connected to a synchronous belt 49 for transmission.

[0032] By setting up the above structure, the motor C47 drives multiple driven wheels 44 to rotate synchronously through the drive wheel 48 and the synchronous belt 49. When the driven wheels 44 rotate, they drive multiple rotary tillage plates 45 to rotate continuously through the rotating cylinder 43. The multiple rotary tillage plates 45 located inside the soil continuously till the soil.

[0033] like Figure 5As shown, the nitrogen fertilizer addition component 5 includes a storage hopper 51 fixedly mounted on the top of the connecting frame 1 and extending into the inner side of the U-shaped mounting frame 31. It is welded from stainless steel sheet, with mirror-polished inner and outer walls, allowing for long-term storage of nitrogen fertilizers such as urea without rust or material deterioration. This prevents the fertilizer from absorbing moisture, clumping, or sticking to the walls, ensuring smooth feeding throughout the process. A rotating shaft B52 is nested within the bottom of the storage hopper 51 via a ball bearing. Gears 53 are rotatably connected to both ends of the rotating shaft B52 via one-way bearings. 2. A feeding roller 54, which is fixedly sleeved on the middle of the outer side and seals the bottom opening of the storage hopper 51, is also made of stainless steel. It can adapt to extreme working environments with high humidity and strong corrosion and has a longer service life. Multiple storage troughs 55 are evenly opened on the outer side of the feeding roller 54. The one-way bearing setting can prevent the rotating shaft B52 from rotating when the rack 69 drives the gear 53 to rotate in the opposite direction. This avoids the situation where the mixture cannot continue to slide down after the mixture inside the deep burial cylinder 41 is full, resulting in nitrogen fertilizer accumulation on the grass roots after local crushing.

[0034] By setting the above structure, after the rack 69 meshes with the gear 53, the rack 69 continues to rise. The rack 69 drives the feeding roller 54 with multiple storage troughs 55 to rotate at the bottom of the inner cavity of the storage hopper 51 through the gear 53 and the rotating shaft B52. At this time, the nitrogen fertilizer inside the storage hopper 51 is continuously output downward by the multiple storage troughs 55. The output nitrogen fertilizer falls into the crushed grass roots to form a mixture. Then the mixture enters the interior of the multiple deep burial cylinders 41 through the top opening of the deep burial cylinder 41.

[0035] like Figure 6As shown, the mixture deep burial assembly 6 includes a sealing plate 61 fixedly installed at the bottom right side of the U-shaped mounting bracket 31. A motor D62 is fixedly installed at the top right side of the sealing plate 61. The output shaft of the motor D62 extends to the left side of the sealing plate 61 and is fixedly connected to a rotating disk 63. A drive slide rod 64 is rotatably nested at the bottom left side of the rotating disk 63 via a bearing. Both the rotating disk 63 and the drive slide rod 64 are made of 45# steel. The mixture deep burial assembly 6 also includes two guide shafts 65 fixedly installed at the right end of the inner side of the U-shaped mounting bracket 31. The guide shafts are made of GCr15 bearing steel. A lifting frame 66 is slidably sleeved on the outer side of the two guide shafts 65 in the vertical direction via a linear bearing. Both the lifting frame 66 and the lifting frame 66 are made of Q355B low alloy high strength steel. The surface is hot-dip galvanized. The middle of the side of the lifting frame 66 is provided with a drive groove 67 that is compatible with the drive slide rod 64. The drive slide rod 64 is slidably set inside the drive groove 67. Multiple push columns 68 are evenly fixed at the bottom of the drive groove 67, which are located directly above the adjacent rotating cylinders 43. The push columns 68 are made of 304 stainless steel, with a smooth surface and low coefficient of friction. They can be smoothly inserted into the deep burial cylinder 41 to squeeze and push the mixture. This not only completely eliminates the problem of material blockage of the mixture, but also accurately pushes the mixture to a depth of 20cm in the soil for deep burial. Compared with traditional surface spreading, the grass root decomposition cycle is shortened by more than 50%. Both ends of the left side of the lifting frame 66 are fixedly connected with racks 69 that are compatible with the adjacent gears 53.

[0036] By setting up the above structure, the motor D62 drives the rotating disk 63 to rotate continuously. During the rotation of the rotating disk 63, the driving slide rod 64 and the driving slide groove 67 drive the lifting frame 66 to rise linearly along the two guide shafts 65. When the lifting frame 66 rises, it drives multiple push columns 68 to be pulled out from the inside of the adjacent buried cylinders 41, thereby releasing the seal on the top opening of the buried cylinder 41. At the same time as the push columns 68 release the seal, the rack 69, which rises synchronously due to the lifting frame 66, meshes with the adjacent gear 53 and drives the subsequent gear 53 to rotate continuously. The multiple push columns 68 continue to move down under the drive of the lifting frame 66 and enter the multiple buried cylinders 41. The mixture inside the deep-buried cylinder 41 is continuously pushed, and then continuously output through the mixture outlet 42 to the deep soil (about 20 cm deep). The mixture is then buried by the soil thrown up by the rotary tillers 45 during rotary tillage. By pushing the mixture out by the push column 68, not only can the deep-buried cylinder 41 be prevented from clogging, but the mixture can also be buried deep in the soil, thereby effectively increasing the speed of grass roots decomposing into organic fertilizer. In addition, the addition of urea can also compensate for the nitrogen consumed when grass roots decompose, further increasing the decomposition speed while preventing the grass roots from competing for nitrogen during decomposition, which would lead to poor crop growth.

[0037] The specific working process of this invention is as follows:

[0038] Connect the connecting frame 1 to the tractor head, and then the tractor head drives the device to move in the land. During the movement, the hydraulic system on the tractor head drives the lower parts of multiple disc rakes 23 and multiple deep-buried cylinders 41 into the soil. During the subsequent movement, motors A24, B39, C47 and D62 are all powered on and started.

[0039] Motor A24 drives multiple disc rakes 23 to rotate counterclockwise continuously via rotating shaft A22, thereby turning over the grass roots in the soil. At the same time, the turned-over grass roots are thrown towards the inclined screen plate 36 by the centrifugal force generated when the disc rakes 23 rotate. They then land on the top of the inclined screen plate 36 and slide along the inclined screen plate 36. During this process, the soil that is also thrown over passes through the inclined screen plate 36 and falls down, while the grass roots enter the crushing cylinder 34 through the grass root inlet 35.

[0040] Motor B39 drives the crushing blade 38 to rotate continuously inside the crushing cylinder 34, thereby crushing the grass roots that have entered the crushing cylinder 34. After crushing, qualified grass roots pass through the arc-shaped screen 37 and fall to the top of the guide slope 32. Then, under the guidance of the guide slope 32, they continue to slide towards the top opening of the deep burial cylinder 41.

[0041] Motor C47 drives multiple driven wheels 44 to rotate synchronously via drive wheel 48 and synchronous belt 49. When the driven wheels 44 rotate, they drive multiple rotary tillage plates 45 to rotate continuously via rotating cylinder 43. The multiple rotary tillage plates 45 located inside the soil continuously till the soil.

[0042] Motor D62 drives the rotating disk 63 to rotate continuously. During the rotation of the rotating disk 63, the lifting frame 66 is driven to rise linearly along the two guide shafts 65 through the drive slide rod 64 and drive slide groove 67. When the lifting frame 66 rises, it drives multiple push columns 68 to be pulled out from the inside of the adjacent buried cylinder 41, thereby releasing the blockage of the top opening of the buried cylinder 41.

[0043] As the push column 68 releases the blockage, the rack 69, which rises synchronously due to the lifting frame 66, meshes with the adjacent gear 53. Subsequently, as the lifting frame 66 continues to rise, the rack 69 drives the discharge roller 54 with multiple storage troughs 55 to rotate at the bottom of the inner cavity of the storage hopper 51 through the gear 53 and the rotating shaft B52. At this time, the nitrogen fertilizer inside the storage hopper 51 is continuously output downward by the multiple storage troughs 55. The output nitrogen fertilizer falls into the crushed grass roots to form a mixture. Then the mixture enters the interior of the multiple deep burial cylinders 41 through the top opening of the deep burial cylinder 41.

[0044] The lifting frame 66 moves down along the two guide shafts 65 under the drive of the drive slide rod 64 and the drive slide groove 67. During the downward movement, the rack 69 drives the gear 53 to rotate in the opposite direction. At this time, due to the action of the one-way bearing, the rotating shaft B52 does not rotate, thus avoiding the situation where the mixture cannot continue to slide down after the mixture inside the deep buried cylinder 41 is full, resulting in the accumulation of nitrogen fertilizer on the grass roots after local crushing.

[0045] Multiple push columns 68 continuously move downward under the drive of the lifting frame 66 and enter the interior of multiple deep-buried cylinders 41, and then continuously push the mixture inside the deep-buried cylinders 41, so that the mixture is continuously output to the depth of the soil through the mixture outlet 42, and then the mixture is buried by the soil thrown up by the multiple rotary tillage plates 45 during rotary tillage.

[0046] It is worth noting that the control of each electrical component in this application is achieved by a programmable controller, and the control program can be easily implemented by those skilled in the art through simple programming, so it will not be elaborated on here.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
