Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, specifically to a combined suspended traction four-fertilizer belt layered positioning and quantitative fertilization device. Background Technology

[0002] In agricultural planting, in order to increase crop yield, it is usually necessary to apply various fertilizers. Nowadays, most fertilization is done manually or by fertilizer truck. Manual fertilization is to use fertilizer applicators to spread fertilizer in the field. This method is not only time-consuming and labor-intensive, but also exposes a large number of crops to trampling. Manual fertilization means that fertilizer cannot be effectively distributed around the roots of the crops.

[0003] Publication number CN116998291A discloses a quantitative fertilization device for land conditions, including a frame, side plate, fertilizer box, fixing plate, hole-digging component, mounting frame, and fertilization component; the hole-digging component can dig holes to be fertilized at corresponding positions during the hole-digging process, and the fertilization component can deliver fertilizer during the fertilization process and cover and bury the holes after fertilization.

[0004] However, the aforementioned patents can only apply fertilizer at the same depth, and the fertilizer's effect is relatively concentrated. This makes it impossible for the coating of soil suitable for planting crops to fully benefit from the fertilizer's effects, which is not conducive to quickly improving soil fertility.

[0005] Based on this, the present utility model is proposed. Utility Model Content

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0026] Example 1:

[0027] like Figure 1 and Figure 2As shown, this combined suspended traction four-layer positioning and quantitative fertilization equipment includes: a frame 1, wheels 2, a shallow fertilization mechanism 3, a deep fertilization mechanism 4, a spreading mechanism 5, shovels 6, bulldozers 7, and soil levelers 8. The frame 1 is a metal frame that serves as the overall support structure for the equipment. There are two wheels 2, symmetrically mounted on both sides of the frame 1 via connecting frames. This combined suspended traction four-layer positioning and quantitative fertilization equipment requires the use of a traction device. Specifically, a traction component is installed on the frame 1, and then a tractor is connected to the traction component, allowing the tractor to tow the equipment. Several shovels 6 are evenly spaced on the frame 1. The bottom of each shovel 6 is wedge-shaped, with the pointed end facing the direction of the equipment's movement, allowing it to penetrate the soil and create furrows as the equipment moves, forming ridges on both sides of the furrows. Several shallow fertilization mechanisms 3 are evenly spaced at the bottom of the frame 1, and these mechanisms are used to apply fertilizer to the shallow soil layer of the ridges. Several deep fertilization mechanisms 4 are installed at equal intervals at the bottom of the frame 1. These mechanisms apply fertilizer to the deeper soil layers of the ridges. Each deep fertilization mechanism 4 corresponds to one of several shallow fertilization mechanisms 3. The deep and shallow fertilization mechanisms 4 and 3 are staggered relative to the direction of the equipment's movement by 4-6 cm, ensuring even fertilizer distribution and preventing overlap. Several shovels 6 are staggered with each deep fertilization mechanism 4, ensuring that each shovel 6 is equidistant from its adjacent deep fertilization mechanism 4. This ensures that the position of the formed ridges corresponds to the positions of the deep and shallow fertilization mechanisms 4 and 3, guaranteeing that the fertilization is applied correctly to the ridges. A spreading mechanism 5 is installed on the frame 1 and delivers fertilizer to both the deep and shallow fertilization mechanisms 4 and 3. Several bulldozers 7 are installed on the side of the frame 1 away from the shovels 6, with each bulldozer 7 corresponding to a different shovel 6. The bottom of each bulldozer 7 is wedge-shaped, with its pointed end facing the direction of movement. Symmetrically arranged outward-sloping push plates are located on both sides of the bottom of each bulldozer 7. As the equipment moves, the two push plates of each bulldozer 7 level the soil on both sides of the furrow. A soil leveler 8 is installed on the side of the frame 1 away from the shovels 6 and is used to level and shape the soil.

[0028] refer to Figure 6The shallow fertilization mechanism 3 includes two shallow fertilization sections, each comprising: a first mounting frame 31, a first mounting plate 32, a first crossbar 33, a first adjusting frame 34, a first furrow opener 35, a first fertilizer trough 36, and a first feed inlet 37. The first mounting frame 31 is connected to the frame 1. The first mounting plate 32 is mounted on the first mounting frame 31 and is U-shaped, with its opening facing away from the frame 1. There are two first crossbars 33, each mounted within the first mounting plate 32. The first adjusting frame 34 is mounted within the first mounting plate 32 and slides on the first crossbar 33. The width of the inner cavity of the first mounting plate 32 is 2-4 cm larger than the width of the first adjusting frame 34. The first furrow opener 35 is mounted at the bottom end of the first adjusting frame 34. A first fertilizer trough 36 is formed on the circumferential edge of the first furrow opener 35. A first feed inlet 37 is mounted on the first adjusting frame 34. The first feed inlet 37 has a fertilizer channel, and its bottom end extends into the first fertilizer trough 36. After the fertilizer falls through the channel in the first feed inlet 37, it can pass through the first fertilizer trough 36, ensuring that the fertilizer is concentrated and discharged within the width of the first fertilizer trough 36. In order to adjust the distance between the two shallow fertilization sections, a first lead screw 38 is installed through the corresponding position on the outer wall of the first feed inlet 37 in the two shallow fertilization sections. Nuts are installed on both sides of the outer wall of the first feed inlet 37 in the two shallow fertilization sections, and the nuts are threadedly connected to the first lead screw 38. By rotating the nuts individually, the first adjusting frame 34 can be finely adjusted within the first mounting plate 32 along the axial direction of the first crossbar 33.

[0029] refer to Figure 5The deep fertilization mechanism 4 includes two deep fertilization sections, each comprising: a second mounting frame 41, a second mounting plate 42, an extension frame 43, a second crossbar 44, a second adjusting frame 45, a second furrow opener 46, a second fertilizer trough 47, a second feed inlet 48, and a spring 410. The second mounting frame 41 is connected to the frame 1. The second mounting plate 42 is mounted on the second mounting frame 41. The second mounting plate 42 is U-shaped, with its opening facing away from the frame 1. The extension frame 43 is mounted inside the second mounting plate 42. There are two second crossbars 44, each mounted inside the extension frame 43. The second adjusting frame 45 is mounted inside the extension frame 43 and slidably mounted on the second crossbar 44. The inner width of the extension frame 43 is 2-4 cm wider than the width of the second adjusting frame 45. The second furrow opener 46 is mounted at the bottom end of the second adjusting frame 45. The second furrow opener 46 has a second fertilizer trough 47 on its circumferential edge. A second feed inlet 48 is mounted on the second adjusting frame 45. The second feed inlet 48 has a fertilizer channel, and its bottom end extends into the second fertilizer trough 47. After the fertilizer falls through the channel in the second feed inlet 48, it can pass through the second fertilizer trough 47, ensuring that the fertilizer is concentrated and discharged within the width of the second fertilizer trough 47. The two ends of the spring 410 are fixedly connected to the second adjusting frame 45 and the extension frame 43, respectively. The extension frame 43 is inclined forward from the top to the bottom of the frame 1 to ensure that the second furrow opener 46 is far from the first furrow opener 35, avoiding interference. The tension of the spring 410 helps to stabilize the second adjusting frame 45. In order to adjust the distance between the two deep fertilization sections, second lead screws 49 are installed through the corresponding positions on the outer walls of the second adjusting frame 45 in the two deep fertilization sections. Nuts are installed on both sides of the outer wall of the second adjustment frame 45 in the two deep fertilization sections, and the nuts are threadedly connected to the second lead screw 49. By rotating the nuts individually, the second adjustment frame 45 can be finely adjusted within the extension frame 43 along the axial direction of the second crossbar 44.

[0030] It is worth noting that the longitudinal height of the shallow fertilization mechanism 3 in this embodiment is 10-15 cm smaller than the longitudinal height of the deep fertilization mechanism 4. This ensures that shallow and deep trenching and fertilization can be performed separately.

[0031] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8The feeding mechanism 5 includes: a fertilizer box 51, a discharge port 52, a control chamber 53, a rotating shaft 54, a control wheel 55, a feeding plate 56, and a flexible hose 57. The fertilizer box 51 is installed at the top of the frame 1 and has an open, hollow structure. Several discharge ports 52 are located at the bottom of the fertilizer box 51, with two ports forming a group and arranged in two rows. The two rows of discharge ports 52 correspond to the shallow fertilization mechanism 3 and the deep fertilization mechanism 4, respectively. Several control chambers 53 are installed on the lower surface of the fertilizer box 51, and the positions of the control chambers 53 correspond to the positions of the discharge ports 52. There are two rotating shafts 54, each corresponding to the positions of the shallow fertilization mechanism 3 and the deep fertilization mechanism 4, and both rotating shafts 54 rotate through the control chambers 53. The control wheel 55 is rotatably installed in the control chamber 53 and is fixedly connected to the rotating shaft 54. Six feeding plates 56 are equidistantly mounted on the outer wall of the control wheel 55 along the circumference. Rotation of the control wheel 55 causes the feeding plates 56 to rotate within the control cavity 53. The space between adjacent feeding plates 56 is a storage space where fertilizer enters. As this space rotates from top to bottom, the fertilizer is discharged. Controlling the rotation of the control wheel 55 controls the fertilizer feeding rate. A hose 57 is installed at the bottom of the control cavity 53 for conveying fertilizer. The bottom ends of the front hoses 57 are connected to the second inlet 48 in the deep fertilization mechanism 4, and the bottom ends of the rear hoses 57 are connected to the first inlet 37 in the shallow fertilization mechanism 3. To drive the two rotating shafts 54 to rotate coaxially, the feeding mechanism 5 also includes: a motor 58, a first gear 59, a first toothed belt 510, a second gear 511, and a second toothed belt 512. There are two second gears 511, each fixedly mounted on one of the two rotating shafts 54. The two second gears 511 are meshed with a second toothed belt 512, which drives the two second gears 511 to rotate synchronously. A motor 58 is mounted on the frame 1. There are two first gears 59; one is mounted at the output end of the motor 58, and the other is fixedly mounted on one of the rotating shafts 54. The two first gears 59 are meshed with a first toothed belt 510, which drives the two first gears 59 to rotate synchronously. Turning on the motor 58 drives the connected first gear 59 to rotate. The first toothed belt 510 drives the other first gear 59 to rotate one of the rotating shafts 54, and the engagement of the second gears 511 and the second toothed belt 512 ensures that the two rotating shafts 54 rotate synchronously.

[0032] In addition, a plate 53a is inserted into the control cavity 53. The plate 53a is located on top of the control wheel 55. Pulling the plate 53a controls the depth of its insertion into the control cavity 53, which can control the amount of fertilizer that enters the control cavity 53 per unit time from the fertilizer box 51.

[0033] Furthermore, in this embodiment, the output end of the motor 58 is connected to the first gear 59 via a speed changer. By controlling the speed changer, the rotation of the shaft 54 ​​can be precisely controlled, thereby precisely controlling the amount of fertilizer fed.

[0034] refer to Figure 9 The soil leveler 8 has a cylindrical main body, and several leveling blocks 801 are evenly spaced on its outer wall, with the leveling blocks 801 corresponding to the positions of several shovels 6 and bulldozers 7. The leveling blocks 801 are used to level the ridges. Rubber sheets 802 are installed on the main body of the soil leveler 8 between two adjacent leveling blocks 801, and the rubber sheets 802 are used to assist in leveling the soil between the two adjacent ridges.

[0035] Example 2:

[0036] refer to Figure 10 , Figure 11 , Figure 12 and Figure 13 The difference between this embodiment and embodiment 1 is that a turning mechanism 9 is provided at the bottom of the fertilizer box 51. The turning mechanism 9 can push the fertilizer inside the fertilizer box 51 while the fertilizer is being discharged, so that the fertilizer moves between them and avoids the fertilizer from being piled up and making it difficult to discharge.

[0037] The flipping mechanism 9 includes: guide wall 91, soft pad 92, cam 93, drive rod 94, first slide groove 95, second slide groove 96, push rod 97, and lever 98. There are two guide walls 91, symmetrically installed in the fertilizer box 51. The two guide walls 91 are inclined inwards from top to bottom to ensure that the fertilizer tends to concentrate inwards. The soft pad 92 is installed between the two guide walls 91. There are two cams 93, respectively installed on two rotating shafts 54, which can rotate synchronously. The cams 93 are eccentrically positioned, having a proximal end and a distal end, and the two cams 93 are arranged in opposite directions. There are two drive rods 94, rotatably installed on the fertilizer box 51. There are four first slide grooves 95, divided into two symmetrically arranged groups. Two of the first slide grooves 95 in each group are respectively opened on both sides of the fertilizer box 51, located at the bottom of the guide wall 91 and the soft pad 92. There are two second slide grooves 96, symmetrically opened on the outer wall of the fertilizer box 51. Both the first slide groove 95 and the second slide groove 96 are arc-shaped and coaxial. The two ends of the push rod 97 are slidably installed in the two first slide grooves 95 of the same group, with one end of the push rod 97 connected to the drive rod 94 and the push rod 97 connected to the soft pad 92. One end of the lever 98 is connected to the drive rod 94, and the other end of the lever 98 extends into the fertilizer box 51 through the second slide groove 96 and contacts the cam 93.

[0038] The working principle of the above structure is as follows: Rotation of the shaft 54 ​​drives the cam 93 to rotate. When the distal end of the cam 93 contacts the lever 98, it drives the drive rod 94 to rotate, causing the push rod 97 to rise and push the soft pad 92 upwards, thus allowing the material in the fertilizer box 51 to flow. Conversely, when the lever 98 contacts the proximal end of the cam 93, the drive rod 94 flips using the fertilizer and its own gravity, pulling the soft pad 92 downwards. Because the two cams 93 are set in opposite directions, the two drive rods 94 rotate alternately, achieving alternating pulling of the soft pad 92. This pushes the fertilizer, preventing difficulties in discharging due to accumulation.

[0039] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
