Abstract
Description
Technical Field
[0001] This invention relates to the field of soil improvement technology for mountain orchards, and in particular to an organic fertilizer burial device for rapid soil maturation in mountain orchards. Background Technology
[0002] Soil maturation refers to the process of continuously improving soil tilth and fertility through various technical measures, transforming raw soil into mature soil. Mature soil has a deep soil layer, high organic matter content, good soil structure, and coordinated water, fertilizer, air, and heat fertility factors. It also exhibits vigorous microbial activity and a strong ability to supply crops with water and nutrients. Composting organic fertilizer can effectively improve orchard soil. Its main principles are increasing soil organic matter, improving soil structure, regulating pH, and promoting the reproduction of soil microorganisms. This enhances the soil's water retention, fertilizer retention, and aeration capacity, creating favorable conditions for fruit tree growth. Mountainous orchards have complex terrain and uneven surfaces, making it difficult for large agricultural machinery to enter and operate. Small rotary tillers are generally used to dig ditches in the orchards. However, the working depth of rotary tillers is only 20 to 25 centimeters, while the appropriate depth for burying organic fertilizer for deep-rooted fruit trees is about 40 to 60 centimeters. Small rotary tillers are not suitable for ditching operations. In addition, mountainous orchards are usually uneven and the soil is hard and compacted. Rotary tillers are prone to bumping and jumping, which affects the stability of operation and the quality of cultivation, and also accelerates the wear of the blades.

[0011] Preferably, one end of the connecting disc is fixedly connected to a sprocket, which is located inside the second fixed cover, and a chain guide is installed at the turning point of the chain inside the second fixed cover.

[0014] Preferably, a bulldozer blade is installed on one side of the rotary tiller frame, and the side wall of the bulldozer blade has a "V" shaped cross section.
[0015] Compared with related technologies, the organic fertilizer burial device for rapid soil maturation in mountain orchards provided by this invention has the following beneficial effects: This invention provides an organic fertilizer burial device for rapid soil maturation in mountain orchards. During trenching operations, the rotary tiller blades rotate on the soil surface. Due to external forces such as rainfall or irrigation, the structure of the soil surface is easily damaged, the soil material disperses, and a hard crust or crust forms after drying. The continuously counterclockwise rotating rotary tiller blades first break up the hard crust or crust, making the soil surface soft and reducing the resistance of the fixed shaft and the blades in trenching. The fixed shaft and the blades are inclined in the soil layer, increasing the contact area between the blades and the soil, which facilitates soil breaking. Furthermore, the first fixed shaft rotates counterclockwise, and the second fixed shaft rotates clockwise. The fixed shaft drives the blades to rotate, pushing the soil between the first fixed shaft and the second fixed shaft outward. The spiral blades also push the soil upward, thereby pushing the broken soil outward. The diameters of the first and second fixed shafts and the width of the blades gradually decrease from top to bottom, reducing the resistance to rotation of the fixed shafts and blades within the soil layer. Simultaneously, a "V"-shaped orchard trench with a depth of at least 40 cm is created in the soil. Since orchards are typically uneven and the soil is compacted and hard, rotary tillers are prone to bumping and jumping. The working depth of the rotary tiller blades is approximately 15 cm, and at this depth, the rotating fixed shafts are tilted within the soil layer. The reduced soil support and working depth increase the stability of the rotary tiller blades during operation and extend their service life. Because the longest vertical distance between the two rotary tiller blades is greater than the maximum vertical distance between the first and second fixed shafts, from a top-down perspective, the rotary tiller... The working range of the blades on the soil surface is much larger than that of the fixed shaft, increasing the working area of the rotary tiller blades on the surface of the mountain orchard, increasing the area of loosened surface soil, and facilitating soil maturation in the mountain orchard. Because the first fixed shaft rotates counterclockwise and the second fixed shaft rotates clockwise, the fixed shafts drive the rotating blades downwards into the soil, thereby driving the support and the rotary tiller blades downwards. This ensures the rotary tiller blades are in close contact with the ground, increasing their stability. However, the large contact area between the rotary tiller blades and the soil increases the force-bearing area, making it easier to evenly distribute the downward thrust generated by the blade rotation into the soil, preventing the fixed shaft and blades from drilling into the soil, and facilitating the forward movement of the fixed shaft and blades to create trenches.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in Figure 1 This is a schematic diagram of a preferred embodiment of the organic fertilizer burial device for rapid soil maturation in mountain orchards provided by the present invention. Figure 2 This is a schematic diagram of organic fertilizer burial provided by the present invention; Figure 3 for Figure 1 The diagram shows a grooving process using a blade. Figure 4 for Figure 1 The diagram shows the internal structure of the mounting box. Figure 5 for Figure 2 The storage box structure shown is a top view. Figure 6 for Figure 2 The diagram shows an enlarged view of the structure at point A. Figure 7 for Figure 2The diagram shows a bulldozer blade structure. The organic fertilizer compaction device for rapid soil maturation in mountain orchards includes a rotary tiller frame 2. One end of the rotary tiller frame 2 is rotatably connected to a mounting box 10, and the bottom end of the rotary tiller frame 2 is equipped with a hydraulic rod 4 for driving the mounting box 10 and the support 13 to rotate up and down. To facilitate the operation of the hydraulic rod 4, the mounting box 10 and the support 13 are rotated, causing the rotary tiller blades 11 and the fixed shaft 16 to enter the soil layer.
[0020] One end of the mounting box 10 is fixedly connected to the funnel-shaped bracket 13. One end of the bracket 13 is symmetrically rotatably connected to a connecting plate 19. The connecting plate 19 is connected to a rotating shaft 17 via a coupling 20. Multiple rotary tillage blades 11 are mounted on the surface of the rotating shaft 17 to agitate the surface soil. The height of the rotary tillage blades 11 gradually decreases from the center of the rotating shaft 17 towards its edge. This design increases the working depth of the rotary tillage blades 11 in the soil layer, facilitating subsequent ditching and preventing the rotary tillage blades 11 from penetrating other areas. The excessive size reduces the working intensity of the rotary tiller blades 11; the bottom surface of the mounting box 10 is symmetrically and tilted to connect the first fixed shaft 5 and the second fixed shaft 16. The side walls of both the first fixed shaft 5 and the second fixed shaft 16 are fixedly connected to spiral blades 6 used for creating deep trenches on the soil surface. The height of the first fixed shaft 5 and the second fixed shaft 16 is greater than the height of the rotary tiller blades 11; when it is necessary to create deep trenches inside the soil, the hydraulic rod 4 is opened, so that the angle between the fixed shaft and the rotary tiller frame 2 is approximately 70°, the rotary tiller blades 11 penetrate the soil to a depth of approximately 15 cm, and the fixed shaft penetrates the soil to a depth of approximately 45 cm; during trenching operations, the rotary tiller blades 11 rotate on the soil surface, due to... Under the influence of external forces such as rainfall or irrigation, the surface structure of the soil layer is easily damaged, the soil material disperses, and a hard crust or crust forms after drying. The continuously counterclockwise rotating rotary tillage blades 11 first break up the hard crust or crust, making the soil surface soft and reducing the resistance of the fixed shaft and the blades 6 in trenching the soil layer. The fixed shaft and the blades 6 are inclined in the soil layer, increasing the contact area between the blades 6 and the soil, making it easier to break up the soil. Furthermore, the first fixed shaft 5 rotates counterclockwise and the second fixed shaft 16 rotates clockwise. The fixed shaft drives the blades 6 to rotate, pushing the soil between the first fixed shaft 5 and the second fixed shaft 16 outward. The spiral-shaped blades 6 rotate and push the soil upward, thereby pushing the broken soil outward. The diameters of the first fixed shaft 5 and the second fixed shaft 16 gradually decrease from top to bottom. The sidewall cross-sections of the first fixed shaft 5, the second fixed shaft 16, and the blade 6 are arranged in a "V" shape, which reduces the resistance of the fixed shaft 5 and the blade 6 rotating inside the soil layer. At the same time, a "V" shaped orchard trench with a trench depth of not less than 40 cm is dug in the soil layer. Since orchards are usually uneven and the soil is hard and compacted, the rotary tiller is prone to bumping and jumping. The working depth of the rotary tiller blade 11 is about 15 cm, and at this time the rotating fixed shaft is tilted inside the soil layer. The support of the soil layer and the reduction of the working depth increase the stability of the rotary tiller blade 11 during construction and extend the service life of the rotary tiller blade 11.Because the longest vertical distance between the two rotary tiller blades 11 is greater than the maximum vertical distance between the first fixed shaft 5 and the second fixed shaft 16, from a top-down perspective, the working range of the rotary tiller blades 11 on the soil surface is much larger than that of the fixed shaft. This increases the working area of the rotary tiller blades 11 on the surface of the mountain orchard, increasing the area of loosened surface soil and facilitating soil maturation in the mountain orchard. Since the first fixed shaft 5 rotates counterclockwise and the second fixed shaft 16 rotates clockwise, the fixed shaft drives the rotating blades 6 downwards into the soil, thereby causing the support 13 and the rotary tiller blades 11 to move downwards. This ensures that the rotary tiller blades 11 are in close contact with the ground, increasing their stability. However, because the contact area between the rotary tiller blades 11 and the soil is large, the force-bearing area is increased, making it easier to evenly distribute the downward thrust generated by the rotation of the blades 6 into the soil. This prevents the fixed shaft and the blades 6 from drilling downwards into the soil, facilitating the forward movement of the fixed shaft and the blades 6 to create trenches.
[0021] The mounting box 10 and the bracket 13 are equipped with a second fixing cover 8 on their side walls, and the rotary tiller frame 2 is equipped with a first fixing cover 7 on its side wall. One end of the second fixing cover 8 is rotatably connected to the interior of the first fixing cover 7. Multiple sprockets 23 are installed inside the second fixing cover 8. Adjacent sprockets 23 are connected by chains 21. In order to protect the sprockets 23 and the chains 21 from the fixing cover, and to facilitate the rotation of the sprockets 23 and the chains 21.
[0022] The surface of the rotary tiller frame 2 is equipped with a diesel engine 3. The sprocket 23 on the output shaft surface of the diesel engine 3 is connected to the sprocket 23 at one end of the second fixed cover 8 via a chain 21. The connecting chain 21 is gripped inside the first fixed cover 7 and the second fixed cover 8. One end of the connecting disc 19 is fixedly connected to the sprocket 23, which is located inside the second fixed cover 8. In order to facilitate the operation of the diesel engine 3, the sprocket 23 and the chain 21 drive the lead screw 24 and the connecting disc 19 to rotate. The chain 21 is equipped with a chain guide at the turning point inside the second fixed cover 8 to facilitate the curved movement of the chain 21 inside the second fixed cover 8 and to prevent the chain from shifting laterally, jumping or falling off during long-distance or high-speed operation.
[0023] The mounting box 10 is internally connected to a lead screw 24, one end of which is fixedly connected to a sprocket 23. This sprocket 23 is rotatably connected to the interior of the second fixing cover 8. The lead screw 24 meshes with a main gear 26, and the main gear 26 meshes with a second gear 25. The mounting box 10 is internally connected to the main gear 26, the second gear 25, and two first gears 22. One of the first gears 22 meshes with the second gear 25, and the second gear 25 drives the other first gear 22 to rotate via a chain 21 and a sprocket 23. To facilitate the lead screw 24 driving the main gear 26 to rotate, and the main gear 26 driving the second gear 25 to rotate, the second gear 25 achieves the rotation of the first gear 22 via the sprocket 23 and the chain 21. The two first gears 22 rotate in opposite directions, causing the sprocket 23 and the chain 21 to rotate in opposite directions.
[0024] The top ends of the first fixed shaft 5 and the second fixed shaft 16 are both fixedly connected to a first gear 22. The first gear 22 and the second gear 25 have the same diameter. In order to make the first gear 22 rotate at the same speed, the first fixed shaft 5 and the second fixed shaft 16 rotate at the same speed. The diameter of the main gear 26 is larger than the diameter of the first gear 22. In order to make the rotation speed of the first gear 22 greater than the rotation speed of the main gear 26, the rotation speed of the fixed shaft and the blade 6 is increased.
[0025] Because the amount of organic fertilizer applied is usually greater than that of chemical fertilizer, and organic fertilizer needs to be buried in trenches, the later construction intensity for workers is high; the side walls of the support 13 and the mounting box 10 are fixedly connected to the mounting plates 12. When using the rotary tillage blades 11, the mounting plates 12 are reinforced with reinforcing rods 9 to increase the stability of the support 13 and the mounting box 10; a storage box 14 is placed on the surface of the support 13 and the mounting box 10, and the bottom of the storage box 14 is symmetrically equipped with supporting rollers 29 to facilitate the movement of the storage box 14 on the bottom surface; multiple connecting plates 27 are fixedly connected to the bottom of the storage box 14, and the connecting plates 27 are connected to the mounting plates 12 by bolts; a feeding funnel 30 is installed at the bottom of the storage box 14, and the inclined bottom surface of the storage box 14 is rotatably connected to the feeding plate 18. Plate 18 is rotatably connected to the interior of the feeding hopper 30; multiple vibrating rods 28 are fixedly connected to the top of the feeding plate 18, and the spherical end of the vibrating rod 28 abuts against and presses the bottom surface of the storage box 14; the connecting shaft 31 is mounted on the surface of the connecting plate 19 through the coupling 20, and multiple ribs 32 are fixedly connected to the side wall of the connecting shaft 31, and the ribs 32 are slidably connected to the feeding plate 18; after the trench is dug in the soil, the rotating shaft 17 at one end of the support 13 is removed, and the connecting shaft 31 is fixed to the surface of the connecting plate 19 through the coupling 20; the storage box 14 is placed on the surface of the support 13 and the mounting box 10, the mounting plate 12 and the connecting plate 27 are aligned and fixed with bolts, and the mounting box 10 is fixed to the surface of the support 13 and the mounting box 10.Open the hydraulic rod 4 so that the angle between the fixed shaft and the rotary tiller frame 2 is approximately 80°, and the fixed shaft penetrates the soil to a depth of approximately 50 cm. Add organic fertilizer into the storage tank 14 through the feed funnel. Propel the rotary tiller frame 2 along the trench. At this time, the first fixed shaft 5 rotates clockwise, and the second fixed shaft 16 rotates counterclockwise. The rotating blade 6 will then emerge from the soil. The blade 6 and the fixed shaft tilt upwards and press against the storage tank 14, reducing the size of the storage tank 14. The resistance to motion occurs when the connecting shaft 31 drives the rib 32 to rotate, causing the rib 32 to continuously push the feed plate 18 to rotate up and down. When the feed plate 18 rotates upward, it pushes the vibrating rod 28 downward, causing the vibrating rod 28 to squeeze and vibrate the bottom surface of the storage box 14. The bottom surface of the storage box 14 vibrates. After the vibrating rod 28 vibrates the storage box 14, it rotates downward along with the feed plate 18. The vibration of the storage box 14 facilitates the movement of the storage box 14. The organic fertilizer enters the feeding hopper 31. Inside the hopper 31, the increased size of the organic fertilizer pushes the feeding plate 18 downwards, increasing the distance between the feeding plate 18 and the feeding hopper 30, facilitating the downward flow of the organic fertilizer into the orchard ditch 1. As the fixed shaft and the blade 6 move forward and come into contact with the organic fertilizer, the first fixed shaft 5 rotates clockwise, and the second fixed shaft 16 rotates counterclockwise. This rotation of the blade 6 pushes the organic fertilizer in the center of the orchard ditch 1 towards the side of the orchard ditch 1. The soil layer in the center of the orchard trench 1 is broken up again by the rotating blades 6 and the fixed shaft, increasing the depth of the orchard trench 1. The broken soil and organic fertilizer move towards the edge of the orchard trench 1, mixing the bottom soil with the organic fertilizer before falling back into the trench 1. This increases the burial depth of the organic fertilizer and improves the deep soil, increasing soil maturation efficiency. Due to the inclined setting of the fixed shaft, the rotating blades 6 squeeze the material downwards, thus keeping the organic fertilizer in the trench and preventing dust from flying upwards. A bulldozer plate 15 is installed on one side of the rotary tiller frame 2, and the side wall of the bulldozer plate 15 has a "V" shaped cross-section. To facilitate the movement of the bulldozer plate 15 by the rotary tiller frame 2, the soil pushed by the bulldozer plate 15 moves towards the center of the bulldozer plate 15, pushing the protrusions on the surface of the orchard trench 1 back into the trench 1, burying the organic fertilizer. This facilitates construction and reduces the workload for workers.
[0026] The working principle of the organic fertilizer burial device for rapid soil maturation in mountain orchards provided by this invention is as follows: An electric drive wheel is installed at the bottom of the rotary tiller frame 2, and a power source for driving the electric drive wheel and the hydraulic rod 4 is installed inside the rotary tiller frame 2. During ditching operations, the diesel engine is activated, driving the fixed shaft and the rotating shaft 17 to rotate via the sprocket 23 and chain 21. The hydraulic rod 4 is opened, so that the angle between the fixed shaft and the rotary tiller frame 2 is approximately 70°, the rotary tiller blades 11 penetrate the soil to a depth of approximately 15 cm, and the fixed shaft penetrates the soil to a depth of approximately 45 cm (as shown in the attached diagram). Figure 1 and attached Figure 3(As shown) During ditching operations, the rotary tiller blades 11 rotate on the soil surface. Due to external forces such as rainfall or irrigation, the structure of the soil surface is easily damaged, the soil material disperses, and a hard crust or crust forms after drying. The continuously counterclockwise rotating rotary tiller blades 11 first break up the hard crust or crust, making the soil surface soft. The fixed shaft and the blades 6 are inclined in the soil layer, increasing the contact area between the blades 6 and the soil, making it easier to break up the soil. The first fixed shaft 5 rotates counterclockwise, and the second fixed shaft 16 rotates clockwise. The fixed shaft drives the blades 6 to rotate, pushing the soil between the first fixed shaft 5 and the second fixed shaft 16 outward. The spiral blades 6 rotate and push the soil upward, thereby pushing the broken soil outward, opening a "V" shaped orchard trench in the soil layer, with a trench depth of not less than 40 cm. Since the longest vertical distance between the two rotary tiller blades 11 is greater than that between the first fixed shaft 5 and the second fixed shaft 16, the rotation of the fixed shaft 5 and the second fixed shaft 16 further contributes to the soil structure. The maximum vertical distance between shaft 5 and the second fixed shaft 16, viewed from above, means that the working range of the rotary tiller blade 11 on the soil surface is much larger than that of the fixed shaft. This increases the working area of the rotary tiller blade 11 on the surface of the mountain orchard, increasing the area of loosened surface soil and facilitating soil maturation. Because the first fixed shaft 5 rotates counterclockwise and the second fixed shaft 16 rotates clockwise, the fixed shaft drives the rotating blade 6 downwards into the soil, thereby causing the support 13 and the rotary tiller blade 11 to move downwards. This ensures the rotary tiller blade 11 is in close contact with the ground, increasing its stability. However, the large contact area between the rotary tiller blade 11 and the soil increases the force-bearing area, making it easier to evenly distribute the downward thrust generated by the rotation of the blade 6 into the soil. This prevents the fixed shaft and the blade 6 from drilling downwards into the soil, facilitating the forward movement of the fixed shaft and the blade 6 to create trenches. After trenches are dug in the soil, remove the rotating shaft 17 from one end of the support 13, and fix the connecting shaft 31 to the surface of the connecting plate 19 using the coupling 20; place the storage box 14 on the surface of the support 13 and the mounting box 10, align the mounting plate 12 and the connecting plate 27 and fix them with bolts, fix the mounting box 10 to the surface of the support 13 and the mounting box 10, and then fix the bulldozer plate 15 to one end of the rotary tiller frame 1. Open the hydraulic rod 4 so that the angle between the fixed shaft and the rotary tiller frame 2 is about 80°, and the fixed shaft penetrates the soil to a depth of about 50 cm (as shown in the attached figure). Figure 2As shown, organic fertilizer is added into the storage tank 14 through the feeding funnel. The electric drive wheel is turned on, pushing the rotary tiller frame 2 to move along the ditch. When the connecting shaft 31 drives the rib 32 to rotate, the rib 32 continuously pushes the feeding plate 18 to rotate up and down, and continuously pushes the vibrating rod 28 to intermittently squeeze and vibrate the bottom surface of the storage tank 14, so that the organic fertilizer can fall into the orchard ditch 1 through the feeding funnel 30. As the fixed shaft and the blade 6 move forward and come into contact with the organic fertilizer, the first fixed shaft 5 rotates clockwise and the second fixed shaft 16 rotates counterclockwise. The rotating blade 6 pushes the organic fertilizer in the center of the orchard ditch 1 toward the edge of the orchard ditch 1. Then, the rotating blade 6 and the fixed shaft break up the soil layer in the center of the orchard ditch 1 again, increasing the depth of the orchard ditch 1. At the same time, the broken soil and organic fertilizer move toward the edge of the orchard ditch 1, so that the bottom soil and organic fertilizer mix and fall into the orchard ditch 1, increasing the burial depth of the organic fertilizer and improving the deep soil and soil maturation efficiency. As the rotary tiller frame 2 moves forward, it drives the bulldozer plate 15 to move, pushing the spikes on the surface of the orchard ditch 1 back into the orchard ditch 1, burying the organic fertilizer.
