Description

Technical Field

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

[0002] Plant protection is a comprehensive effort to prevent and control plant damage caused by pests and ensure healthy plant growth by utilizing multidisciplinary knowledge and a variety of technical measures. Among the many methods of plant protection, fertilization and tillage are effective. Scientific and rational tillage and fertilization techniques can help plants grow stronger and improve their resistance to pests and diseases, thereby reducing the use of chemical pesticides, ensuring the quality and safety of agricultural products and protecting the ecological environment.

[0003] Fertilization can provide plants with various nutrients they need 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 plant growth, but also improves the soil environment and provides better growth conditions for plants.

[0004] Ploughing increases the space between soil particles by turning the soil, which facilitates the infiltration of water and air. It also effectively destroys the overwintering sites of pests, exposing them to the surface where they may be eaten by birds or frozen to death, thereby reducing the base number of pests and alleviating damage to crops in the following year. Furthermore, the rough surface of the soil after plowing is not conducive to the breeding and spread of pests and diseases.

[0005] However, in existing equipment, fertilizing and plowing are generally independent devices, so when treating the soil, it is divided into two processes, which undoubtedly increases the workload of soil maintenance. Therefore, it is necessary to provide a fertilizing and plowing device for plant protection to solve the above problems.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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 present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0042] Example 1

[0043] This embodiment mainly describes the structure and basic principles of the fertilizing and plowing device, specifically:

[0044] like Figures 1-4 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. The connecting end 12 is suitable for connecting to 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 move on the field soil;

[0045] like Figure 1 、 Figure 4 and Figure 6 As shown, two sets of wheel frames 111 are fixedly mounted on both ends of the frame 11, and a central shaft 116 is fixedly mounted on the wheel frames 111 at both ends, and a shaft sleeve 117 is rotatably mounted between the two sets of wheel frames 111 on the same side, and a wheel 18 is fixedly mounted 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 external groove wheel fertilizer discharger in the prior art. The mechanism and principle thereof can be referred to the patent 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. 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. A first sprocket 15 is fixedly installed on the chain shaft 112. A first chain 17 is provided on the first sprocket 15 and the second sprocket 16. When the chain shaft 112 rotates, the rotating rod 14 can be driven to rotate synchronously, thereby driving the groove wheel 191 to rotate, so as to drive the groove wheel fertilizer discharger 19 to work;

[0049] In order to drive the sprocket 112 to rotate, a third sprocket 113 is fixedly mounted on the sprocket 112, and a fourth sprocket (not shown) is fixedly mounted on the shaft sleeve 117. A second chain 114 is provided between the fourth sprocket and the third sprocket 113. When the wheel 18 rolls, the shaft sleeve 117 is driven to rotate synchronously, thereby driving the sprocket 112 to rotate through the second chain 114.

[0050] At the same time, a fertilizer discharge pipe 110 is provided at 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, multiple sets of plowing mechanisms 2 are provided on the shaft sleeve 117. The plowing mechanisms 2 have multiple sets of discs 22. The discs 22 at the two ends are fixedly mounted on the shaft sleeve 117, while the discs 22 in the middle are rotatably mounted on the central shaft 116. Connecting rods 21 are fixedly mounted between the multiple sets of discs 22 so that the multiple sets of discs 22 can rotate synchronously with the shaft sleeve 117.

[0052] At the same time, multiple groups of plowing structures are arranged along the circumferential direction of the disc body 22, and the 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, thereby driving 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 in a quantitative and uniform manner, thereby allowing the fertilizer to evenly enter the already 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 workers.

[0057] Example 2:

[0058] During the process of turning the soil, because the soil is generally moist and has a high viscosity, it may adhere to the plow soil structure and then contaminate 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, Figures 8-12 As shown, multiple groups of grooves 221 are provided on the disc body 22 along the circumferential direction, and two groups of slides 222 are fixedly provided inside the grooves 221 near the outer ring of the disc body 22, thereby forming a slide groove 223 between the two groups of slides 222;

[0060] At the same time, a control console 41 is slidably provided in the chute 223. A slide rod 43 is fixedly installed at one end of the control console 41. The slide rod 43 is adapted to the chute 223. 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. In the initial state, due to the action of the spring 24, the plowing portion 44 is received in the chute 223, and the slide rod 43 is still in the chute 223, closing the chute 223 to prevent soil adhering to the plowing portion 44 from entering the interior of the disc body 22.

[0062] like Figure 6 、 Figure 8 and Figure 11-12 As shown, a cam 23 is rotatably mounted on the central shaft 116. The cam 23 is provided with a first arc 231 with a smaller diameter, a second arc 232 with a larger diameter, and a third arc 235 in sequence along the counterclockwise direction. The second arc 232 and the third arc 235 have the same diameter.

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

[0064] A first transition arc 233 is provided at the connection between the first arc 231 and the second arc 232. The provision of the first transition arc 233 enables the matching arc 42 to switch between the first arc 231 and the second arc 232 at will.

[0065] Continue to refer Figure 11 A step 234 is provided at the connection between the second arc loop 232 and the third arc loop 235. The setting of the step 234 makes it possible for the matching arc 42 to only enter the third arc loop 235 from the second arc loop 232 in one direction, but cannot return to the second arc loop 232 from the third arc loop 235.

[0066] At the same time, a second transition arc 236 is provided between the third arc 235 and the first arc 231. The provision of the second transition arc 236 enables the matching arc 42 to switch between the first arc 231 and the third arc 235 at will.

[0067] Furthermore, a plurality of third transition arcs 237 are provided on the second arc circle 232. The third transition arcs 237 serve as stationary points for the mating arcs 42 and are evenly distributed on the second arc circle 232. Therefore, in the initial state, the mating arcs 42 are located 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 control console 41 and the center of the disk body 22 is minimized, thereby allowing the plowing portion 44 to be completely received in the chute 223.

[0068] like Figure 7 As shown, a limiting mechanism 5 is mounted 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 mounted 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 mounted on the cam 23, and a pawl 52 is rotatably mounted on the fixed shaft 51. The pawl 52 is engaged with the ratchet 55, and a torsion spring 53 is fixedly mounted between the fixed shaft 51 and the pawl 52, so that the cam 23 is rotated. Figure 7 From a different perspective, when the cam 23 rotates clockwise, the pawl 52 can pass over the ratchet 55 without affecting the rotation of the cam 23. When the cam 23 rotates counterclockwise, the pawl 52 abuts against the ratchet 55, thereby stopping the cam 23. 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 sets of plowing portions 44 contact the multiple sets of transition arcs of the cam 23, thereby driving the cam 23 to rotate counterclockwise synchronously due to the action of friction. When the cam 23 rotates to the position where the pawl 52 abuts against the ratchet teeth 55, the cam 23 stops rotating due to the action of resistance. At this time, the second arc 232 is in a vertically downward position.

[0070] At this time, the disc 22 continues to rotate driven by the wheel 18, 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 chute 223 ;

[0072] When the mating arc 42 passes over the first transition arc 233 and contacts the second arc 232, the plowing portion 44 extends from the chute 223 due to the larger diameter of the second arc 232. Furthermore, since the second arc 232 is located in a vertically downward position, the plowing portion 44 contacts the soil after extending 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 sets of third transition arcs 237 on the second arc loop 232, the plowing portion 44 continuously extends and retracts, thereby causing the plowing portion 44 to repeatedly impact the soil, thereby achieving the effect of crushing larger and harder soil, thereby facilitating the soil turning work;

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

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

[0076] In this embodiment, the cleaning groove 34 is provided corresponding to the third arc 235. Thus, when the matching arc 42 passes over the step 234 from the second arc 232 and enters the third arc 235, since the third arc 235 and the second arc 232 have the same diameter, the plowing portion 44 extends out of the chute 223 and is located in the cleaning groove 34. At this time, as the disc 22 continues to rotate, the plowing portion 44 continues to move in the cleaning groove 34 and removes the attached soil with the help of the cleaning brush 35.

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

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

[0079] In this embodiment, when the disc body 22 rotates clockwise, the cam 23 is also synchronously driven to rotate clockwise. At this time, the pawl 52 can pass over the ratchet tooth 55 without affecting the rotation of the cam 23, so that the cam 23 continues to rotate with the disc body 22. When the matching arc 42 is located 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, resulting in excessive turning of the soil, and 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 foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
