Description

Technical Field

[0001] This utility model relates to the field of soil loosening devices, and in particular to a soil loosening device for agricultural experimental fields. Background Technology

[0002] Experimental fields are primarily used to verify whether new varieties, fertilizers, or technologies are suitable for local climate, soil, and environmental conditions. Through experiments in these fields, researchers can collect data and evaluate the effects of different varieties or technologies, thus providing a scientific basis for agricultural production. Experimental fields include small-scale fields. Large machinery cannot be used to loosen the soil in small fields, and the soil texture is relatively loose, which would increase soil density. Therefore, small-scale soil loosening devices are used for loosening operations.

[0003] Existing technologies have certain shortcomings for soil loosening devices in experimental fields. For example, flat blades are prone to problems such as soil sticking or breakage when turning over soil, and they have high resistance to entering the soil, making it impossible to break up the soil in one go. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil loosening device for agricultural experimental fields, which has the advantages of low resistance to soil entry and easy soil breaking, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a soil loosening device for agricultural experimental fields, comprising a rotating wheel, the surface of which is uniformly provided with support pins in a ring, the support pins being uniformly arranged in a linear array on the outer ring of the rotating wheel, a support frame rotatably mounted on both sides of the rotating wheel, a handle fixedly connected between the support frames, the handle being detachably connected to the support frame, a worktable fixedly mounted on the outer ring of the support frame, the worktable including a sub-frame fixedly mounted to the support frame, an extension plate fixedly mounted on the bottom outer ring of the worktable, a motor fixedly mounted on the top of the worktable, a blade assembly rotatably mounted on the bottom of the worktable at the concentric axis of the motor, a soil-crushing device rotatably mounted on one side of the blade assembly on the bottom of the worktable, and a trenching plate fixedly mounted on one side of the soil-crushing device on the bottom of the extension plate.

[0006] With the above-mentioned structural design, in practical applications, this device is driven by a motor to rotate a rotating rod. When the rotating rod rotates, it drives the crushing roller through a transmission belt, causing the soil to be broken up in layers by the bionic curved blades. Due to the setting of the groove plate, the field through which the bionic curved blades travel has grooves, which fill and bury the crops on both sides, achieving the effect of low resistance to soil entry and high crushing degree.

[0007] Preferably, the blade assembly includes a rotating rod, which is fixedly connected to the output shaft of the motor. The outer ring of the rotating rod is provided with four sets of soil-breaking blades. Each soil-breaking blade includes a bracket, and a biomimetic curved blade is fixedly installed at the end of the bracket. The biomimetic curved blade is arc-shaped, and the outer ring of the biomimetic curved blade is provided with ripples that imitate the surface of an earthworm. A transmission groove is opened inside the workbench. A transmission belt is rotatably connected between the rotating rod and the soil-breaking device inside the transmission groove. A protective cover is fixedly installed at the opening of the transmission groove.

[0008] With the above structural design and the bionic curved blade, when the blade assembly rotates, the bionic curved blade rotates in a cycle and slowly enters the soil, breaking the soil in layers along the path, causing the soil to be broken by the bionic curved blade.

[0009] Preferably, the soil crushing device includes two crushing rollers, with gears fixedly sleeved on the top of each crushing roller, the gears on the top of the two crushing rollers meshing with each other, the transmission belt rotatingly sleeved between the rotating rod and the outer ring of the top of one of the crushing rollers, and a protective shell fixedly sleeved on the bottom of the worktable located on the outer ring of the gear.

[0010] With the above-mentioned structural design, the unbroken soil clods come into contact with the crushing roller. After the soil clods come into contact with the crushing roller, they are driven to rotate and thus broken up, achieving a uniform crushing effect.

[0011] Preferably, the groove plate is composed of three trapezoidal plates whose shapes and sizes decrease sequentially. The top trapezoidal plate is the largest and the bottom trapezoidal plate is the smallest. The trapezoidal plates are detachably connected, and the top trapezoidal plate is fixedly installed at the bottom of the extension plate.

[0012] With the above-mentioned structure, the broken soil moves to both sides of the work platform due to the obstruction of the grooved plate, so that the crops on both sides of the work platform are filled and buried by the broken soil, and the broken field has strip-shaped grooves.

[0013] This utility model has the following advantages:

[0014] 1. The soil loosening device used in this agricultural experimental field achieves uniform soil breaking by setting up a blade assembly, a bionic curved blade, and a soil crushing device, thereby reducing the resistance to soil entry. When the bionic curved blade rotates, it is located inside the soil to break it up. Due to the shape of the bionic curved blade, the resistance to entering the soil is reduced when it rotates, allowing the bionic curved blade to enter the soil more quickly. The soil broken up by the bionic curved blade is scattered inside the trench. When the soil that has not been broken into fragments comes into contact with the crushing roller, the rotation of the crushing roller will crush the clumps of soil, so that the clumps of soil are broken up evenly, achieving the effect of uniform soil breaking and reducing the resistance to soil entry.

[0015] 2. The soil loosening device used in this agricultural experimental field achieves trenching and lateral soil covering by setting up structures such as trench plates. Due to the shape of the trench plates, the broken soil cannot move towards the trench plates. Because of the obstruction of the trench plates, the broken soil moves to both sides of the work platform, so that the crops on both sides of the work platform are filled and buried by the broken soil. This creates strip-shaped trenches in the broken field, achieving the effect of lateral soil covering and filling. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3A soil loosening device for an agricultural experimental field includes a rotating wheel 1. The surface of the rotating wheel 1 is uniformly provided with support pins 11 in a ring. The support pins 11 are arranged in a linear array on the outer ring of the rotating wheel 1. Support frames 2 are rotatably mounted on both sides of the rotating wheel 1. Handles 21 are fixedly connected between the support frames 2 and are detachably connected to the support frames 2. A workbench 3 is fixedly mounted on the outer ring of the support frames 2. The workbench 3 includes a sub-frame 31, which is fixedly mounted to the support frames 2. An extension plate 32 is fixedly mounted on the bottom outer ring of the workbench 3. A motor 4 is fixedly mounted on the top of the workbench 3. A blade assembly 5 is rotatably mounted on the bottom of the workbench 3 at the concentric axis of the motor 4. A soil-crushing device 6 is rotatably mounted on one side of the blade assembly 5 at the bottom of the workbench 3. A trench plate 7 is fixedly mounted on one side of the soil-crushing device 6 at the bottom of the extension plate 32.

[0023] In practical applications, this device is driven by the motor 4, which drives the rotating rod 51 to rotate. When the rotating rod 51 rotates, it drives the crushing roller 61 through the transmission belt 54. When the soil is broken up in layers by the bionic curved blade 53, the unbroken soil comes into contact with the crushing roller 61 and is crushed by the crushing roller 61, so that the soil is evenly broken up. Due to the setting of the groove plate 7, the field through which the bionic curved blade 53 travels has grooves, which fill and bury the crops on both sides, achieving the effect of low soil resistance and high crushing degree.

[0024] Please see Figures 1-4 The blade assembly 5 includes a rotating rod 51, which is fixedly connected to the output shaft of the motor 4. The outer ring of the rotating rod 51 is provided with four sets of soil-breaking blades. Each soil-breaking blade includes a bracket 52, and a biomimetic curved blade 53 is fixedly installed at the end of the bracket 52. The biomimetic curved blade 53 is arc-shaped and imitates the design of an earthworm. The outer ring of the biomimetic curved blade 53 is provided with ripples that imitate the surface of an earthworm. During operation, this can reduce the soil penetration resistance of the biomimetic curved blade 53. The inside of the workbench 3 is provided with a transmission groove. The rotating rod 51 and the soil-breaking device 6 are rotatably connected to the transmission belt 54 inside the transmission groove. A protective cover is fixedly installed at the opening of the transmission groove to ensure that the transmission is not affected by the soil.

[0025] With the setting of the bionic curved blade 53, when the blade group 5 rotates, the bionic curved blade 53 rotates in a cycle and slowly enters the soil, breaking the soil in layers along the path, so that the soil is broken by the bionic curved blade 53.

[0026] Please see Figures 1-3 The soil crushing device 6 includes two crushing rollers 61, with gears 62 fixedly sleeved on the top of the crushing rollers 61. The gears 62 on the top of the two crushing rollers 61 mesh with each other. The transmission belt 54 is rotatably sleeved between the rotating rod 51 and the outer ring of the top of one of the crushing rollers 61. The bottom of the workbench 3 is located on the outer ring of the gear 62 and is fixedly sleeved with a protective shell 63 to ensure that the transmission between the gears 62 is not affected by the soil.

[0027] When the crushing roller 61 rotates, it drives another crushing roller 61 to rotate synchronously through the gear 62, so that the uncrushed soil clods come into contact with the crushing roller 61. After the soil clods come into contact with the crushing roller 61, they will be driven to rotate by the crushing roller 61 and thus be crushed, achieving a uniform crushing effect.

[0028] Please see Figures 1-3 The groove plate 7 is composed of three trapezoidal plates whose shapes and sizes decrease sequentially. The top trapezoidal plate is the largest and the bottom trapezoidal plate is the smallest. The trapezoidal plates are detachably connected, and the top trapezoidal plate is fixedly installed at the bottom of the extension plate 32.

[0029] Due to the shape of the trench plate 7, the broken soil cannot move in the direction of the trench plate 7. It is because of the obstruction of the trench plate 7 that the broken soil moves to both sides of the work platform 3, so that the crops on both sides of the work platform 3 are filled and buried by the broken soil, and the broken field has strip-shaped trenches.

[0030] Working principle: In use, first start motor 4. Motor 4 drives the rotating rod 51 to rotate via the output shaft. The rotation of the rotating rod 51 drives the soil-breaking blade and the crushing roller 61 to rotate. The rotating rod 51, located inside the transmission groove via the transmission belt 54, drives one of the crushing rollers 61 to rotate. The rotation of the crushing roller 61, via the gear 62, drives the other crushing roller 61 to rotate in the opposite direction. After starting the device, place it in the test field. The biomimetic curved blade 53, when rotating, enters the soil to break it up. Due to the shape of the biomimetic curved blade 53, it penetrates deep into the soil during rotation. The reduced resistance allows the bionic curved blade 53 to penetrate the soil more quickly. The soil, after being broken up by the bionic curved blade 53, flies around inside the trench. When the soil that has not been broken up comes into contact with the crushing roller 61, the rotation of the crushing roller 61 will crush the clumps of soil, making the clumps of soil evenly broken up. Due to the compression between the soil and the trench plate 7, the soil broken up by the bionic curved blade 53 and the crushing roller 61 will move to both sides to fill and move, so that the field after the device passes through has strip-shaped trenches, allowing the soil in the trenches to enter the soil around the roots of the crops on both sides to fill and bury the soil, thus realizing the soil loosening operation.
