Description

Technical Field

[0001] The present application relates to the technical field of plant protection, and in particular to a fertilizing and tilling device for plant protection. Background Art

[0002] Plant protection is a work that comprehensively utilizes multidisciplinary knowledge and multiple technical measures to prevent and control harmful organisms from harming plants and ensure the healthy growth of plants. Among the many means of plant protection, fertilization and soil plowing are an effective method. Through scientific and reasonable soil plowing and fertilization technology, plants can grow strong and improve their ability to resist the invasion of pests and diseases, thereby reducing the use of chemical pesticides, achieving the purpose of ensuring the quality and safety of agricultural products and protecting the ecological environment;

[0003] Fertilization can provide plants with various nutrients needed for growth, such as nitrogen, phosphorus, potassium and other macroelements, as well as iron, zinc, manganese and other trace elements. When plants obtain sufficient and balanced nutrients, their own immunity will be enhanced, making them more capable of resisting the invasion of pests and diseases. At the same time, reasonable fertilization not only helps the growth of plants, but also improves the soil environment and provides better growth conditions for plants.

[0004] Ploughing can increase the space between soil particles by turning the soil, which is conducive to the penetration of water and air. At the same time, plowing can effectively destroy the overwintering sites of pests, exposing the overwintering pests to the surface, where they may be eaten by birds or frozen to death, thereby reducing the base number of pests and reducing the damage to crops in the next year. The surface of the soil after plowing is rough, which is not conducive to the breeding and spread of pests and diseases.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] Embodiment 1

[0043] This embodiment mainly describes the structure and basic principle of the fertilization and soil plowing device, specifically:

[0044] like Figure 1-Figure 4 As shown, the present application provides a fertilizing and plowing device for plant protection, including a fertilizing mechanism 1, which is used to fertilize the soil. The fertilizing mechanism 1 includes a frame 11, and one end of the frame 11 is provided with a connecting end 12, which is suitable for connecting with an external driving mechanism, such as being hung on a tractor, so that under the action of the external driving mechanism, the fertilizing mechanism 1 can synchronously walk on the field soil;

[0045] like Figure 1 , Figure 4 and Figure 6 As shown, two sets of wheel frames 111 are fixedly installed at both ends of the frame 11, and a central shaft 116 is fixedly installed on the wheel frames 111 at both ends, and a shaft sleeve 117 is rotatably installed between the two sets of wheel frames 111 on the same side, and a wheel 18 is fixedly installed on the shaft sleeve 117, so that under the action of an external driving mechanism, the wheel 18 is suitable for rolling to drive the fertilizer application mechanism 1 to move synchronously;

[0046] like Figure 1-Figure 5As shown, a fertilizer box 13 is fixedly installed at the upper end of the frame 11, and a plurality of groove wheel fertilizer dischargers 19 are connected to the lower end of the fertilizer box 13. The groove wheel fertilizer dischargers 19 are connected to the fertilizer box 13 and are used to discharge the fertilizer in the fertilizer box 13. In this embodiment, the groove wheel fertilizer discharger 19 adopts the outer groove wheel fertilizer discharger in the prior art, and its mechanism and principle can refer to the patent with publication number CN206181792 U, which will not be described in detail here, and the groove wheel fertilizer discharger 19 has a groove wheel 191;

[0047] In order to drive the groove wheel fertilizer discharger 19 to work, a driving assembly is installed on the frame 11, and the driving assembly includes side plates 118 fixedly installed on both sides of the upper end of the frame 11, and a rotating rod 14 is rotatably installed between the two sets of side plates 118, and the groove wheel 191 is fixedly installed on the rotating rod 14;

[0048] At the same time, a second sprocket 16 is fixedly installed on one side of the rotating rod 14, and a chain shaft 112 is installed on the upper end bearing of the wheel frame 111, and a first sprocket 15 is fixedly installed on the chain shaft 112. The first sprocket 15 and the second sprocket 16 are provided with a first chain 17 for transmission, so that when the chain shaft 112 rotates, the rotating rod 14 can be driven to rotate synchronously, and then the groove wheel 191 can be driven to rotate, so as to drive the groove wheel fertilizer discharger 19 to work;

[0049] In order to drive the chain shaft 112 to rotate, a third sprocket 113 is fixedly mounted on the chain shaft 112, and a fourth sprocket (not shown in the figure) is fixedly mounted on the shaft sleeve 117. A second chain 114 is arranged between the fourth sprocket and the third sprocket 113, so that when the wheel 18 rolls, the shaft sleeve 117 can be driven to rotate synchronously, and then the chain shaft 112 is driven to rotate through the second chain 114.

[0050] At the same time, a fertilizer discharge pipe 110 is connected to the bottom of the groove wheel fertilizer discharger 19, and a fertilizer discharge shovel 115 is connected to the fertilizer discharge pipe 110, so that fertilizer can be discharged from the groove wheel fertilizer discharger 19 through the fertilizer discharge pipe 110 and the fertilizer discharge shovel 115 and applied to the soil surface;

[0051] like Figure 1 and Figure 2 As shown, a plurality of plowing mechanisms 2 are arranged on the shaft sleeve 117, and the plowing mechanism 2 has a plurality of discs 22, wherein the discs 22 at the two ends are fixedly mounted on the shaft sleeve 117, and the discs 22 in the middle are rotatably mounted on the central shaft 116, and connecting rods 21 are fixedly mounted between the plurality of discs 22, so that the plurality of discs 22 can rotate synchronously with the shaft sleeve 117;

[0052] At the same time, a plurality of groups of soil plowing structures are arranged on the disc body 22 along the circumferential direction, and the soil plowing structures are adapted to rotate synchronously with the disc body 22 to turn the soil;

[0053] In summary, under the action of the external driving mechanism, the wheels 18 can roll synchronously to travel on the soil that needs to be turned;

[0054] When the wheel 18 rolls, the disc 22 can be driven to rotate synchronously, so as to drive the plowing structure to turn the soil;

[0055] At the same time, the rotation of the wheel 18 drives the groove wheel 191 to rotate, so as to guide the fertilizer to the soil quantitatively and evenly, so that the fertilizer can evenly enter the turned soil;

[0056] Therefore, through the synchronous operation of plowing and fertilizing, the soil can be turned and fertilized synchronously, thereby reducing the difficulty of soil maintenance and reducing the workload of staff.

[0057] Embodiment 2:

[0058] In the process of turning the soil, because the soil is generally moist and has great viscosity, it may adhere to the plow soil structure and then pollute the plow soil structure, so subsequent cleaning work is required, which undoubtedly increases the burden on the staff;

[0059] In order to solve the above problems, Figure 8-Figure 12 As shown, a plurality of grooves 221 are provided on the disc body 22 along the circumferential direction, and two sets of slides 222 are fixedly provided inside the grooves 221 near the outer ring of the disc body 22, so that a slide groove 223 is formed between the two sets of slides 222;

[0060] At the same time, a control console 41 is slidably arranged in the slide groove 223, and a slide rod 43 is fixedly installed at one end of the control console 41. The slide rod 43 is adapted to the slide groove 223, and a plowing part 44 is rotatably installed at one end of the slide rod 43. The plowing part 44 is used to turn the soil;

[0061] A spring 24 is fixedly installed between the console 41 and the groove 221, so that in the initial state, due to the action of the spring 24, the plowing part 44 is received in the slide groove 223, and the slide rod 43 is still in the slide groove 223, and the slide groove 223 is closed to prevent the soil adhered to the plowing part 44 from entering the interior of the disc body 22;

[0062] like Figure 6 , Figure 8 and Figure 11-Figure 12 As shown, a cam 23 is rotatably mounted on the central shaft 116, and a first arc 231 with a smaller diameter, and a second arc 232 and a third arc 235 with larger diameters are sequentially arranged on the cam 23 in a counterclockwise direction, and the second arc 232 and the third arc 235 have the same diameter;

[0063] Meanwhile, a matching arc 42 is provided on the console 41, so that during the rotation of the disk 22, the matching arc 42 will sequentially contact the first arc circle 231, the second arc circle 232 and the third arc circle 235;

[0064] A first transition arc 233 is provided at the connection between the first arc 231 and the second arc 232. The first transition arc 233 is provided so that the matching arc 42 can switch between the first arc 231 and the second arc 232 at will.

[0065] Continue to refer Fig.11 A step 234 is provided at the connection between the second arc circle 232 and the third arc circle 235. The step 234 is provided so that the matching arc 42 can only enter the third arc circle 235 from the second arc circle 232 in one direction, but cannot return to the second arc circle 232 from the third arc circle 235.

[0066] Meanwhile, a second transition arc 236 is provided between the third arc 235 and the first arc 231. The second transition arc 236 is provided so that the matching arc 42 can switch between the first arc 231 and the third arc 235 at will.

[0067] Furthermore, a plurality of third transition arcs 237 are arranged on the second arc circle 232. The third transition arcs 237 are used as stationary points of the matching arcs 42 and are evenly distributed on the second arc circle 232. Therefore, in the initial state, the matching arcs 42 are distributed at the lowest points of the first transition arc 233, the second transition arc 236 and the third transition arc 237. At this time, the distance between the console 41 and the center of the disk body 22 is the smallest, so that the plowing part 44 is completely received in the slide groove 223.

[0068] like Figure 7 As shown, a limiting mechanism 5 is installed on the central shaft 116, and the limiting mechanism 5 is used to limit the rotation direction of the cam 23. The limiting mechanism 5 includes a ratchet 54 fixedly installed on the central shaft 116, and a single ratchet 55 is provided on the ratchet 54. At the same time, a fixed shaft 51 is fixedly installed on the cam 23, and a pawl 52 is rotatably installed on the fixed shaft 51. The pawl 52 is engaged with the ratchet 55, and a torsion spring 53 is fixedly installed between the fixed shaft 51 and the pawl 52, so that Figure 7 From the perspective, when the cam 23 rotates clockwise, the pawl 52 can pass over the ratchet 55 without affecting the rotation of the cam 23, and when the cam 23 rotates counterclockwise, the pawl 52 will abut against the ratchet 55, so that the cam 23 stops rotating. Because the position of the ratchet 55 is fixed, the position of the cam 23 remains fixed each time it stops;

[0069] In summary, when the disc 22 starts to rotate counterclockwise, the multiple groups of plowing parts 44 are in contact with the multiple groups of transition arcs of the cam 23, so that the cam 23 is driven to rotate counterclockwise synchronously due to the friction force. When the cam 23 rotates to the position where the pawl 52 and the ratchet 55 abut against each other, the cam 23 stops rotating due to the resistance. At this time, the second arc 232 is located in a vertical downward position.

[0070] At this time, the disc 22 is still driven by the wheel 18 to continue to rotate, so that the matching arc 42 moves in contact with the cam 23 in the counterclockwise direction;

[0071] When the matching arc 42 contacts the first arc circle 231, the plowing portion 44 is completely received in the slide groove 223;

[0072] When the matching arc 42 passes over the first transition arc 233 and contacts the second arc circle 232, the plowing portion 44 extends out from the slide groove 223 due to the larger diameter of the second arc circle 232. Since the second arc circle 232 is located in a vertically downward position, the plowing portion 44 contacts the soil after extending out, and continuously turns the soil as the wheel 18 rotates, thereby achieving the purpose of turning the soil.

[0073] At this time, due to the presence of the multiple groups of third transition arcs 237 on the second arc circle 232, the plowing part 44 is continuously extended and retracted, so that the plowing part 44 repeatedly impacts the soil, so as to achieve the effect of crushing the larger and harder soil, thereby facilitating the soil turning work;

[0074] At the same time, the repeated extension and retraction of the plowing part 44 allows the soil adhering to the plowing part 44 to contact the side wall of the chute 223, thereby achieving the effect of removing part of the soil adhering to the plowing part 44, so as to prevent excessive soil from contaminating the disc body 22;

[0075] Further, such as Figure 2 and Figure 5 As shown, a cleaning mechanism 3 is also installed on the frame 11, and the cleaning mechanism 3 is used to completely remove the soil attached to the plowing part 44. The cleaning mechanism 3 includes a cleaning seat 31 fixedly installed on the frame 11, and a cleaning plate 32 is fixedly installed on the cleaning seat 31. A cleaning groove 34 is arranged on the cleaning plate 32. The cleaning groove 34 is a channel for the plowing part 44 to pass through. At the same time, a cleaning brush 35 is arranged inside the cleaning groove 34. The cleaning brush 35 is suitable for contacting with the plowing part 44 to remove the soil attached to the plowing part 44;

[0076] In this embodiment, the cleaning groove 34 is arranged corresponding to the third arc circle 235, so that when the matching arc 42 passes over the step 234 from the second arc circle 232 and enters the third arc circle 235, since the third arc circle 235 has the same diameter as the second arc circle 232, the plowing part 44 extends out of the slide groove 223 and is located in the cleaning groove 34. At this time, as the disc body 22 continues to rotate, the plowing part 44 continues to move in the cleaning groove 34 and relies on the cleaning brush 35 to remove the attached soil;

[0077] As the disc body 22 continues to rotate, the matching arc 42 passes over the second transition arc 236 and returns to the initial position. At this time, the soil plowing portion 44 that has been cleaned escapes from the cleaning groove 34 and is recovered into the chute 223.

[0078] Further, such as Figure 5 and Fig.12 As shown, a gear 45 is fixedly mounted on the plowing part 44, and a rack 33 is provided on the cleaning plate 32, and the rack 33 and the gear 45 are meshed with each other, so that when the plowing part 44 is located in the cleaning groove 34, the rack 33 and the gear 45 are meshed with each other and drive the plowing part 44 to rotate, so that the plowing part 44 is fully in contact with the cleaning brush 35 in the circumferential direction, so as to further improve the cleaning effect;

[0079] In this embodiment, when the disc body 22 rotates clockwise, the cam 23 is also synchronously driven to rotate clockwise, and at this time, the pawl 52 can pass over the ratchet 55 without affecting the rotation of the cam 23, so that the cam 23 continues to rotate with the disc body 22, and when the matching arc 42 is distributed at the lowest point of the first transition arc 233, the second transition arc 236 and the third transition arc 237, the friction between the matching arc 42 and the cam 23 is the largest, so that the matching arc 42 is maintained at this position;

[0080] As a result, under the action of the external driving mechanism, plowing operations can only be performed in one direction, which can avoid repeated turning of the soil in the same place and causing excessive turning of the soil. The one-way turning of the soil can also be coordinated with the fertilizing mechanism 1, so that fertilizer can be applied after the turning of the soil is completed, thereby ensuring the rationality of the integrated operation of soil turning and fertilization.

[0081] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
