Description

Technical Field

[0001] This invention belongs to the field of agricultural fertilization technology, specifically relating to an organic fertilizer spreading device for fields. Background Technology

[0002] With the development of modern agriculture, farmland management is gradually shifting towards efficiency, environmental protection, and sustainability. While traditional fertilization methods can meet the basic needs of crop growth, the overuse of chemical fertilizers often leads to soil degradation and environmental pollution. To reduce these negative impacts, organic fertilizers, as environmentally friendly and renewable fertilizers, are gradually becoming an important choice in agricultural production. Unlike chemical fertilizers, organic fertilizers not only provide the nutrients needed for crop growth but also improve soil structure, enhance soil biological activity, and promote sustainable farmland development. However, traditional organic fertilizer application methods are often inefficient and labor-intensive, making them difficult to meet the needs of large-scale agricultural production. With continuous technological advancements, the design and performance of modern organic fertilizer application devices are constantly being optimized, becoming an important tool for promoting green agriculture and achieving sustainable agricultural development.

[0003] Organic fertilizer is widely used in fields. It is taken from nature and used for nature, which is in line with the contemporary green development concept. Existing organic fertilizer spreading devices for fields usually spread organic fertilizer by rotating two discs. However, organic fertilizer has a high moisture content and is prone to clumping, which makes it difficult to ensure uniformity in spreading organic fertilizer, thus reducing the spreading effect. At the same time, the spreading device can only spread to a limited area, which limits its application scenarios and greatly reduces the working performance of the spreading device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an organic fertilizer spreading device for fields.

[0005] The technical solution adopted to solve the above technical problems is: an organic fertilizer spreading device for fields, including a connecting frame, a support frame fixedly connected to one end of the connecting frame, a driving mechanism installed inside the support frame, and a spreading mechanism installed at the bottom of the driving mechanism away from the support frame, which is used to cooperate with the driving mechanism to destroy the organic fertilizer and increase the uniformity of the organic fertilizer spreading range.

[0006] The spreading mechanism includes a forward spreading disc, and a reverse spreading disc is connected to the upper inner wall of the forward spreading disc via a sliding groove. This reverse connection is used to drive the organic fertilizer to rotate in both directions. Three support columns are fixedly connected to the bottom of the reverse spreading disc. Inside the three support columns, ball bearings are slidably connected to upward-curved pads. These pads are used to push the reverse spreading disc up and down with the slope of the pads to break up the organic fertilizer. A disc is fixedly connected to the bottom of each of the three pads.

[0007] Furthermore, a hopper is fixedly connected to the top of the connecting frame, and the hopper is provided with an inlet and an outlet at its top and bottom, respectively, for loading and unloading organic fertilizer.

[0008] With the above technical solution, when in use, the connecting frame is connected to the power machinery on the side away from the support frame, so that the organic fertilizer spreading device for the field can work normally in the area where fertilizer needs to be spread. Then, the organic fertilizer is put in from the feed port at the top of the hopper, and then spread in conjunction with other mechanisms.

[0009] Furthermore, a conveying mechanism is installed at the discharge end of the discharge port away from the inlet. The conveying mechanism includes a first motor, and a conveying roller is fixedly connected to the output end of the first motor. Conveying components are rotatably connected to the outer wall of the conveying roller on both sides of the center plate of the hopper discharge port. The two conveying components respectively send the organic fertilizer into the center of the corresponding reverse spreading disc, and the other end of the conveying component is rotatably connected to the inner side of the connecting frame.

[0010] With the above technical solution, once the organic fertilizer is ready, it will flow out from the discharge port. At this time, the conveying mechanism will be used to transfer the organic fertilizer in the hopper to ensure that the organic fertilizer can pass through smoothly and flow to the central area of ​​the spreading machine. Specifically, the first motor is started to drive one of the conveying rollers to rotate. Then, with the support of the other conveying roller, the conveying component in the prior art will be driven to smoothly transfer the organic fertilizer to the central position of the corresponding spreading machine.

[0011] Furthermore, the drive mechanism includes a second motor, with drive shafts fixedly connected to both sides of the output end of the second motor. A first T-shaped gear is fixedly connected to the other end of each of the two drive shafts. The second motor drives the first T-shaped gear to rotate and mesh with a second T-shaped gear. Universal joint nodes are fixedly connected to the tops of the two second T-shaped gears located inside the support frame. Connecting nodes are movably connected to the two universal joint nodes on the side away from the second T-shaped gears via cross-shaped nodes. Another universal joint node is movably connected to the two connecting nodes on the side away from the second T-shaped gears. This is used to drive the reverse spreading disc to reverse the organic fertilizer, while the angle adjustment is buffered by the two universal joint nodes and the connecting nodes.

[0012] Through the above technical solution, as the organic fertilizer is conveyed, the drive mechanism provides a driving force for spreading, and can be adjusted according to the spreading requirements to ensure that the organic fertilizer always falls smoothly into the center of the spreading device during the selection of the spreading row spacing, ensuring the processing and spreading uniformity of the organic fertilizer. Specifically, the second motor is started to drive the two drive shafts to rotate through the second T-shaped gear meshing with the first T-shaped gear, which in turn drives the two universal joints connected by the connecting nodes to rotate. It should be noted that the two universal joints and the cross-shaped joint can effectively change the direction of rotation during the rotation process, and the connecting nodes can effectively cope with the change of the spreading center position during the adjustment process.

[0013] Furthermore, an adjustment mechanism is installed inside the support frame. The adjustment mechanism includes a movable groove, and a hydraulic cylinder is movably connected inside the movable groove. Two first adjusting rods that are bent upwards are rotatably connected to the piston ends on both sides of the hydraulic cylinder. The bent ends of the four first adjusting rods are connected to a support shaft at the recessed part of the support frame. The support frame is also provided with an arc-shaped groove inside the support frame, in which the piston end of the hydraulic cylinder drives the four first adjusting rods to rotate around the support shaft as the rotation center. Four second adjusting rods are rotatably connected to the protruding part of the support frame away from the connecting frame. The other ends of every two first adjusting rods pull the corresponding disc and form a traction with the corresponding second adjusting rod to tilt outwards.

[0014] Through the above technical solution, during the movement of the organic fertilizer spreading device in the field, the choice can be made according to the spreading needs, selecting between area spreading and linear spreading, thereby improving the performance of the spreading device. When the spreading device is on a plane, it is area spreading; when the spreading device is tilted, it is linear spreading. Specifically, when the hydraulic cylinder is activated, its piston end extends away from both sides of the hydraulic cylinder. This will drive the four first adjusting rods to rotate around the corresponding support shaft as the center. One end of every two first adjusting rods will move in the arc groove. It should be noted that because the first adjusting rod is bent, its end point changes position during rotation, thus driving the hydraulic cylinder to move accordingly in the movable groove, thereby not affecting the normal support function. The other end will move towards the center of the hydraulic cylinder. At the same time, under the traction of the corresponding second adjusting rod, the two discs tilt outward, thereby achieving linear spreading and reducing the area. It should be understood that during this movement, the center position of the disc is moved, and the length of the connecting node is sufficient to meet the position movement of the disc, so that the organic fertilizer can still fall to the center position during the tilting process.

[0015] Furthermore, each of the two universal joint nodes is fixedly connected to a rotating shaft on the side away from the connecting node. A first gear is fixedly connected to the outer wall of each of the two rotating shafts. A second gear is provided inside each of the two discs. Multiple teeth mesh between the inside of the forward spreading disc and the second gear. The meshing of the first and second gears drives the multiple teeth to rotate the forward spreading disc in the forward direction. A connecting disc is fixedly connected to the top of each of the two rotating shafts on the side away from the corresponding universal joint node. Springs are provided on the outer walls of multiple support columns located between the connecting disc and the disc. The outer walls of the two connecting discs respectively limit the rotation of the upper disc of the corresponding forward spreading disc, and the lower discs of the two forward spreading discs respectively limit the rotation of the corresponding disc.

[0016] Through the above technical solution, when organic fertilizer is transported from the conveying mechanism to the spreading mechanism, the spreading mechanism uses the up-and-down movement of the inner disc to break up the wet, heavy, and clump-like organic fertilizer. Simultaneously, the inner and outer discs rotate in different directions; the clockwise rotation of the outer disc spreads the fertilizer further, while the counter-clockwise rotation of the inner disc helps control the spreading direction. The different rotation directions of the two discs also increase the degree of breakage. This not only increases the spreading area but also improves the spreading precision, resulting in a more uniform fertilizer distribution and reduced waste. Specifically, with the two discs rotating... The rotation of the shaft, through the meshing of the first and second gears and multiple teeth, causes the forward spreading disc to rotate clockwise, thereby spreading the organic fertilizer. During straight spreading, any organic fertilizer that leaks to the side can be spread on the lower disc of the forward spreading disc. At the same time, the tops of the two rotating shafts will drive the connecting disc to rotate counterclockwise. As the rotation continues, the three support columns rise and fall with the slope of the corresponding pads, forming a reciprocating motion. Under the limit of the connecting disc, the springs on the outer walls of the three support columns will provide a rebound force to assist in breaking.

[0017] The beneficial effects of the present invention are as follows: (1) By designing a conveying mechanism, a driving mechanism, an adjusting mechanism, and a spreading mechanism, the present invention can, when the organic fertilizer spreading device is used, cause the organic fertilizer to collide during the spreading process through the bidirectional rotation of the spreading mechanism, and at the same time break up the organic fertilizer with high moisture content and clumps, so that the organic fertilizer is spread irregularly during the spreading process, and thus spread more evenly. In addition, by adjusting the tilt of the spreading mechanism through the adjusting mechanism, the field organic fertilizer spreading device can be used for both planar spreading and straight-line spreading, thereby enhancing the working performance of the organic fertilizer spreading device; (2) By designing a conveying mechanism, the present invention can transfer organic fertilizer from the material The bucket is used to transport the organic fertilizer out along two paths, and then it is spread through the spreading mechanism so that the spreading device can work normally; (3) The present invention uses a driving mechanism, an adjustment mechanism and a spreading mechanism to make the organic fertilizer that falls into pieces have a certain buffer force to break it. Then, the organic fertilizer is irregular in the forward and reverse directions, so that the organic fertilizer can be spread evenly. At the same time, under the internal reverse and external forward rotation, the organic fertilizer that falls into pieces can be broken more thoroughly. At the same time, the tilt angle of the spreading mechanism can be adjusted so that the organic fertilizer can be switched at will between planar spreading and straight spreading, and the spacing between spreading rows can be controlled.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figures 1-9 As shown, an organic fertilizer spreading device for fields in this embodiment includes a connecting frame 11, a support frame 14 fixedly connected to one end of the connecting frame 11, and a hopper 12 fixedly connected to the top of the connecting frame 11. The hopper 12 is provided with an inlet 13 and an outlet 15 at its top and bottom, respectively. The inlet 13 and the outlet 15 are used for loading and unloading organic fertilizer. In use, the side of the connecting frame 11 away from the support frame 14 is connected to the power machinery, so that the organic fertilizer spreading device for fields can work normally in the area where fertilizer needs to be spread. Then, the organic fertilizer is put into the inlet 13 at the top of the hopper 12, and then spread in conjunction with other mechanisms.

[0030] like Figure 4As shown, a conveying mechanism 2 is installed at the discharge port 15, which is away from the inlet 13. The conveying mechanism 2 includes a first motor 21. The output end of the first motor 21 is fixedly connected to a conveying roller 22. The outer wall of the conveying roller 22 is rotatably connected to both sides of the center plate of the discharge port 15 of the hopper 12. The two conveying components 23 respectively send the organic fertilizer into the center of the corresponding reverse spreading disc 511. The other end of the conveying component 23 is rotatably connected to the inner side of the connecting frame 11. When the organic fertilizer is ready, it will flow out from the discharge port 15. At this time, the conveying mechanism 2 is used to transfer the organic fertilizer in the hopper 12 to ensure that the organic fertilizer can pass smoothly through the transport and flow to the center area of ​​the spreading machine. Specifically, the first motor 21 is started to drive one of the conveying rollers 22 to rotate. Then, under the support of the other conveying roller 22, the conveying component 23 in the prior art is driven to smoothly transfer the organic fertilizer to the center position of the corresponding spreading machine.

[0031] like Figures 6-7 As shown, a drive mechanism 3 is installed inside the support frame 14. The drive mechanism 3 includes a second motor 31. Drive shafts 32 are fixedly connected to both sides of the output end of the second motor 31. A first T-gear 33 is fixedly connected to the other end of each of the two drive shafts 32. The second motor 31 drives the first T-gear 33 to rotate and mesh with a second T-gear 34. Universal joint nodes 35 are fixedly connected to the tops of the two second T-gears 34 located inside the support frame 14. Connecting nodes 36 are movably connected to the two universal joint nodes 35 on the side away from the second T-gears 34 through a cross-shaped node. Another universal joint node 35 is movably connected to the two connecting nodes 36 on the side away from the second T-gears 34. This is used to drive the reverse spreading disc 511 to reverse the organic fertilizer. At the same time, the two universal joint nodes... The buffer angle adjustment of nodes 35 and 36 is achieved by using the drive mechanism 3 to provide a driving force for the spreading of organic fertilizer as it is conveyed. This force can be adjusted according to the spreading requirements to ensure that the organic fertilizer always falls smoothly into the center of the spreading device during the selection of the spreading row spacing, thus ensuring the uniformity of the organic fertilizer processing and spreading. Specifically, the second motor 31 is started to drive the two drive shafts 32 to rotate through the second T-shaped gear 34 meshing with the first T-shaped gear 33. This, in turn, drives the two universal joint nodes 35 connected by the connecting node 36 to rotate. It should be noted that the two universal joint nodes 35 and the cross-shaped node can effectively change their direction during rotation, while the connecting node 36 effectively responds to changes in the central position of the spreading during the adjustment process.

[0032] like Figures 6-7As shown, an adjustment mechanism 4 is installed inside the support frame 14. The adjustment mechanism 4 includes a movable groove 41, and a hydraulic cylinder 42 is movably connected inside the movable groove 41. Two first adjustment rods 43 that are bent upwards are rotatably connected to the piston ends on both sides of the hydraulic cylinder 42. The bent parts of the four first adjustment rods 43 are connected to the recesses of the support frame 14 and a support shaft 44. The support frame 14 is provided with an arc-shaped groove 45 inside, which drives the four first adjustment rods 43 to rotate around the support shaft 44 as the rotation center. Four second adjustment rods 46 are rotatably connected to the protruding part of the support frame 14 away from the connecting frame 11. The other end of each pair of first adjustment rods 43 pulls the corresponding disc 51 and the corresponding second adjustment rod 46 to form a traction to tilt outwards. During the movement of the organic fertilizer spreading device in the field, the choice can be made according to the spreading needs. It can be selected from area spreading and straight spreading, so as to improve the performance of the spreading device. When the spreading device is on a plane, it is area spreading. When the spreading device tilts, it achieves straight-line spreading. Specifically, the hydraulic cylinder 42 is activated, and its piston end extends away from both sides of the hydraulic cylinder 42. This drives the four first adjusting rods 43 to rotate around the corresponding support shaft 44. One end of each pair of first adjusting rods 43 will move in the arc-shaped groove 45. It should be noted that because the first adjusting rods 43 are bent, their end points change position during rotation, thus driving the hydraulic cylinder 42 to move accordingly in the movable groove 41, thereby not affecting the normal support function. The other end will move towards the center of the hydraulic cylinder 42. At the same time, under the traction of the corresponding second adjusting rod 46, the two discs 51 tilt outward, thereby achieving straight-line spreading and reducing the area. It should be understood that during this movement, the center position of the disc 51 is moved. The length of the connecting node 36 is sufficient to allow the disc 51 to move, so that the organic fertilizer can still fall to the center position during the tilting process.

[0033] like Figure 5 and Figures 8-9As shown, a spreading mechanism 5 is installed at the bottom of the drive mechanism 3 away from the support frame 14. This mechanism works in conjunction with the drive mechanism 3 to break up the organic fertilizer and increase the uniformity of the spreading range. The spreading mechanism 5 includes a forward spreading disc 57, and a reverse spreading disc 511 is connected to the upper sliding groove on the inner wall of the forward spreading disc 57. This reverse connection drives the organic fertilizer to rotate in both directions. Three support columns 59 are fixedly connected to the bottom of the reverse spreading disc 511. Inside the three support columns 59, ball bearings are slidably connected to upward-curved pads 52. These pads 52 move up and down, pushing the reverse spreading disc 511 to break up the organic fertilizer. A disc is fixedly connected to the bottom of each of the three pads 52. 51, where two universal joint nodes 35 are fixedly connected to rotating shafts 53 on the side away from connecting node 36, and first gears 54 are fixedly connected to the outer walls of the two rotating shafts 53. Second gears 55 are provided inside the two discs 51. Multiple teeth 56 mesh with the second gears 55 inside the forward spreading disc 57. The meshing of the first gears 54 and second gears 55 drives the multiple teeth 56 to rotate the forward spreading disc 57 in the forward direction. Connecting discs 58 are fixedly connected to the top of the two rotating shafts 53 on the side away from the corresponding universal joint node 35. Springs 510 are provided on the outer walls of multiple support columns 59 located between the connecting discs 58 and the discs 51. The outer walls of disc 58 are respectively limited by the upper disc of the corresponding forward spreading disc 57, and the lower discs of the two forward spreading discs 57 are respectively limited by the corresponding disc 51. When organic fertilizer is transported to the spreading mechanism 5 by the conveying mechanism 2, the spreading mechanism 5 will use the up-and-down movement of the inner disc to break up the wet and heavy clumps of organic fertilizer. At the same time, the inner and outer discs rotate in different directions. The clockwise rotation of the outer disc spreads the fertilizer further, while the counterclockwise rotation of the inner disc helps control the spreading direction of the fertilizer. The different rotation directions of the two discs increase the degree of breakage. In this way, not only is the spreading range increased, but the spreading accuracy is also improved, making the fertilizer distribution more uniform and reducing waste. Specifically, as the two rotating shafts 53 rotate, the meshing of the first gear 54, the second gear 55, and multiple teeth 56 causes the forward spreading disc 57 to rotate clockwise, thereby spreading the organic fertilizer. During straight spreading, any organic fertilizer that leaks to the side can be spread on the lower disc of the forward spreading disc 57. At the same time, the tops of the two rotating shafts 53 will drive the connecting disc 58 to rotate counterclockwise. As the rotation continues, the three support columns 59 rise and fall with the slope of the corresponding pads 52, forming a reciprocating motion. Under the limit of the connecting disc 58, the springs 510 on the outer walls of the three support columns 59 will provide a rebound force to assist in breaking.

[0034] The working principle of this embodiment is as follows: In use, the side of the connecting frame 11 away from the support frame 14 is connected to the power machinery. When the organic fertilizer is ready, it will flow out from the discharge port 15. The first motor 21 is started to drive one of the conveying rollers 22 to rotate. Then, under the support of the other conveying roller 22, the conveying component 23 in the prior art conveys the organic fertilizer. Then, the second motor 31 is started to drive the other end of the two drive shafts 32 to rotate the second T-shaped gear 34 that meshes with the first T-shaped gear 33. This drives the two universal joint nodes 35 connected by the connecting node 36 to rotate. Finally, with the connection of the corresponding universal joint nodes 35, as the two rotating shafts 53 rotate, through the meshing of the first gear 54, the second gear 55, and multiple teeth 56, the forward spreading disc 57 rotates clockwise, thereby spreading the organic fertilizer. During straight spreading, there is some side leakage of organic fertilizer. The system can spread fertilizer on the lower plate of the forward spreading disc 57. At the same time, the tops of the two rotating shafts 53 will drive the connecting disc 58 to rotate counterclockwise. As the rotation continues, the three support columns 59 will rise and fall with the slope of the corresponding pads 52 to form a reciprocating motion. Under the limit of the connecting disc 58, the springs 510 on the outer walls of the three support columns 59 will provide a rebound force to assist in breaking up the fertilizer. During the operation of the organic fertilizer spreading device in the field, when the spreading needs are selected, the hydraulic cylinder 42 is activated, and its piston end extends away from the sides of the hydraulic cylinder 42. At this time, it will drive the four first adjusting rods 43 to rotate around the corresponding support shaft 44. One end of each pair of first adjusting rods 43 will move in the arc groove 45, and the other end will move towards the center of the hydraulic cylinder 42. At the same time, under the traction of the corresponding second adjusting rods 46, the two discs 51 will tilt outward, thereby achieving straight spreading. At this point, the operation of the spreading device ends.
