[0002] As the name suggests, a fertilizer applicator is a machine used for applying fertilizer. It consists of a fertilizer tank, a ditching device, and a covering device. Using a fertilizer applicator, fertilizer can be applied to farmland quickly and easily, thereby reducing the burden of agricultural work.

[0003] In existing technologies, fertilizer applicators, especially ditching devices, have difficulty controlling the depth of the ditch. In addition, some soil clods will appear during the ditching process. When covering the fertilizer, it is difficult to cover all the soil clods with the fertilizer in the ditch, which makes the fertilizer easy to volatilize and fails to achieve the purpose of supplementing the farmland with various nutrients.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] This application provides a fixed-depth fertilizer applicator, which solves the problem of soil clumping during fertilization, affecting fertilizer coverage. In use, it can break up soil clods during fertilization, thereby completely covering the soil with fertilizer and preventing fertilizer evaporation.

[0056] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0057] A crushing section 16 is provided on the side wall of the baffle 15, and soil clods are pushed onto the crushing section 16 to crush the soil clods, thereby enabling the soil to cover the fertilizer more fully.

[0058] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0059] Reference Figures 1-9 A fixed-depth fertilizer applicator includes a frame 10, an mounting plate 11 is provided on the frame 10, and a lifting drive assembly 20 is also provided on the frame 10, the lifting drive assembly 20 being used to drive the mounting plate 11 to lift.

[0060] The mounting plate 11 is equipped with a trenching motor 12, the trenching motor 12 is connected to a commutator 13, the output shaft of the commutator 13 is connected to a connecting shaft 14, and the lower end of the connecting shaft 14 is connected to a blade 30.

[0061] The side wall of the frame 10 is also rotatably connected to a baffle 15, and the baffle 15 is provided with a plurality of crushing parts 16;

[0062] A transmission rod 17 is connected to the side wall of the mounting plate 11, and one end of the transmission rod 17 contacts the side wall of the baffle 15.

[0063] The side wall of the frame 10 is provided with a nut 26, and a bolt 27 is provided on the nut 26. The bolt 27 passes through the nut 26, with one end extending to the outside of the frame 10 and the other end extending to the inside of the frame 10 and rotatably connected to a movable plate 28. The movable plate 28 is connected to the baffle 15 by an elastic member 29.

[0064] Reference Figure 2 , Figure 3 and Figure 6In a further embodiment, the lifting drive assembly 20 includes a drive motor 21, which is mounted on the frame 10.

[0065] The frame 10 is also provided with two ball screws 22, one of which is connected to the power shaft of the drive motor 21. Both ball screws 22 are fitted with transmission wheels 23, and a transmission chain 24 is provided between the two transmission wheels 23.

[0066] Each of the ball screws 22 is also provided with a locking slider 25, and the mounting plate 11 is connected to the locking slider 25.

[0067] The drive motor 21 drives a ball screw 22 to rotate, and at the same time drives a transmission wheel 23 to rotate. Through the transmission chain 24, it drives another transmission wheel 23 and another ball screw 22 to rotate. In this way, the two ball screws 22 can rotate at the same speed and in the same direction, which in turn drives the locking slider 25 to slide on the ball screw 22. Through the self-locking effect between the ball screw 22 and the locking slider 25, the stability of the position of the mounting plate 11 is ensured after the height of the mounting plate 11 is adjusted.

[0068] In a further embodiment, the two ball screws 22 are positioned diagonally opposite each other.

[0069] By adjusting the position of the ball screw 22, the mounting plate 11 can be kept stable during lifting and fixing, and will not tilt.

[0070] In a further embodiment, a hopper 40 is also included, which is located on the frame 10, and a feeding assembly 41 is connected to the lower end of the hopper 40.

[0071] The feeding assembly 41 includes a flow equalization hopper 42, which is connected to the hopper 40. A flow equalization motor 43 is connected to the side wall of the flow equalization hopper 42. The output shaft of the flow equalization motor 43 extends into the flow equalization hopper 42 and is connected to a rotating part 44. A plurality of evenly distributed flow dividers 45 are provided on the rotating part 44. The side wall of the flow divider 45 is in contact with the inner wall of the flow equalization hopper 42.

[0072] The fertilizer can be put into the hopper 40 first. The fertilizer falls into the flow equalization hopper 42 along the hopper 40. The flow equalization motor 43 drives the rotating part 44 and the flow divider 45 to rotate. When the fertilizer falls between the two flow dividers 45, the rotation of the flow equalization motor 43 drives the fertilizer to fall into the telescopic tube 46. The fertilizer continues to fall between other flow dividers 45. In this way, the fertilizer can fall evenly.

[0073] The lower end of the equalizing hopper 42 is connected to a telescopic pipe 46, and the lower end of the telescopic pipe 46 is connected to an inclined discharge pipe 50.

[0074] After adjusting the height of the mounting plate 11, the length of the telescopic tube 46 can also be adjusted so that the lower end of the telescopic tube 46 is close to the bottom of the groove, thus preventing fertilizer from falling out of the groove.

[0075] The telescopic tube 46 includes an inner tube 47 and an outer tube 48. The inner tube 47 and the outer tube 48 are slidably connected, and the size of the inner tube 47 is smaller than that of the outer tube 48. The inner tube 47 is connected to the flow equalization hopper 42, and the outer tube 48 is connected to the discharge pipe 50.

[0076] The inner tube 47 and the outer tube 48 can be configured to slide with damping, so that the height of the inner tube 47 and the outer tube 48 will not change significantly after adjustment. The inner tube 47 is connected to the flow equalization hopper 42, and the outer tube 48 is connected to the discharge pipe 50. This configuration can prevent fertilizer from getting stuck between the inner tube 47 and the outer tube 48, and the fertilizer can smoothly enter the outer tube 48.

[0077] The discharge pipe 50 includes an arc-shaped portion 51, a blocking portion 52, and a pointed portion 53. The arc-shaped portion 51 is connected to the outer pipe 48 and is a pipe with an opening on one side, used to catch the material flowing down from the outer pipe 48. The lower end of the arc-shaped portion 51 is inclined toward one side of the blade 30. The upper end of the blocking portion 52 is connected to the outer pipe 48, and the connection between the blocking portion 52 and the outer pipe 48 is on a different side from that of the arc-shaped portion 51. The lower end of the blocking portion 52 contacts the bottom of the arc-shaped portion 51. The pointed portion 53 is connected to the lower end of the blocking portion 52, and the tip of the pointed portion 53 faces the blade 30.

[0078] The shielding part 52 can block the soil, preventing soil flying off the cutter from entering the curved part 51 and affecting the fertilizer's fall. The pointed part 53 not only breaks up the soil but also creates a small groove, allowing more fertilizer to fall into the groove and further improving the fertilizer's fertility so that it is fully absorbed by the soil.

[0079] In a further embodiment, a shaped rod 60 is connected to the frame 10, one end of the shaped rod 60 is connected to a push plate 61, one side of the push plate 61 is connected to a buffer spring 62, and the other end of the buffer spring 62 is connected to the shaped rod 60.

[0080] The push plate 61 includes a flat plate 63 and a side plate 64. The flat plate 63 is located behind the blade 30, and the side plate 64 is located on the side close to the baffle 15. The lower ends of both the flat plate 63 and the side plate 64 are inclined towards the frame 10.

[0081] As the frame 10 moves, it moves the irregular rod 60, which in turn causes the pusher plate 61 to push the soil, covering the fertilizer in the trough. The buffer spring 62 allows the pusher plate 61 to swing slightly, further improving the effect of covering the soil in the trough.

[0082] Fertilizer can be pushed into the trough through the side plate 64, while the soil can be leveled through the flat plate 63, so that the soil is not uneven, making the farmland look more level and facilitating subsequent operations.

[0083] In a further embodiment, the blade 30 includes a rotary cutting section 31 and a feeding section 32. The rotary cutting section 31 is connected to the connecting shaft 14, and the feeding section 32 is connected to the rotary cutting section 31 and is located above the rotary cutting section 31.

[0084] The material feeding section 32 includes a material plate 33 and a feeding plate 34. The material plate 33 is connected to the rotary cutting section 31. The tilt angle of the material plate 33 is greater than the tilt angle of the rotary cutting section 31. The feeding plate 34 is connected to the edge of the material plate 33. When the material plate 33 and the feeding plate 34 are configured to apply fertilizer, the blade 30 rotates, the material plate 33 first approaches the baffle 15, and the feeding plate 34 then approaches the baffle 15.

[0085] The rotary cutting section 31 can be used to cut trenches in farmland to extract soil, while the material feeding section 32 can feed the soil onto the baffle 15, thereby making better use of the crushing section 16 to crush the soil.

[0086] In a further embodiment, the frame 10 also includes a wheel 70, and a connecting frame 71 is connected to the side of the frame 10 away from the wheel 70.

[0087] The wheels 70 can drive the frame 10 to move quickly, and the connecting frame 71 can easily connect it to other equipment, such as tractors.

[0088] In a further embodiment, the mounting plate 11 is provided with a receiving groove, one end of the transmission rod 17 extends into the receiving groove and is slidably connected to the receiving groove, and one end of the transmission rod 17 is connected to the bottom wall of the receiving groove through a return spring 80.

[0089] As the mounting plate 11 moves downward, the inclined baffle 15 increases the pressure on the transmission rod 17, compressing the return spring 80 and the elastic element 29. This also reduces the inclination angle of the baffle 15, allowing the rotary cutting section 31 to cut out more soil. The smaller baffle angle makes it easier for soil to fall off the baffle 15, preventing excessive soil accumulation. Furthermore, the elastic force of the return spring 80 and the elastic element 29 ensures the effective vibration of the baffle 15.

[0090] In a further embodiment, the crushing section 16 is configured as a pyramid, prism, frustum, or truncated cone, and the crushing section 16 is arranged in a rectangular array or a ring array.

[0091] This setup allows for thorough and complete breakup of compacted soil, ensuring that the soil is completely pulverized.

[0092] In a further embodiment, a roller 81 is provided at the other end of the transmission rod 17, and the roller 81 contacts the side wall of the baffle 15.

[0093] The use of roller 81 can reduce the friction between transmission rod 17 and baffle 15, thus protecting the safety of baffle 15.

[0094] In some embodiments, the crushing sections 16 of each layer are arranged staggered vertically, and the number of crushing sections 16 per unit area of ​​the baffle 15 gradually increases from top to bottom, such that the spacing between the upper crushing sections 16 on the baffle 15 is greater than the spacing between the lower crushing sections 16. In this way, because the baffle 15 is obliquely arranged, the soil clods on the baffle 15 can be impacted as much as possible during the downward movement, improving the thoroughness of soil clod crushing. On the other hand, when stones fly up, they can be blocked and held on the baffle 15 during the fall, avoiding damage to the blade 30 from repeated falling and flying stones. Furthermore, this method not only crushes the soil clods, but also makes the soil distribution more uniform along the width direction of the baffle 15 during the fall of the crushed soil clods, which is more conducive to the covering of fertilizer and / or crops.

[0095] When fertilizing farmland, a tractor or similar equipment can be used to pull the connecting frame 71, causing the wheels 70 to rotate and thus moving the frame 10. During this movement, the lifting drive assembly 20 moves the mounting plate 11, which in turn moves the cutter. Adjusting the cutter's height allows for adjustment of the grooving depth, thus determining the fertilization depth. Adjusting the fertilization depth as needed ensures optimal fertilizer efficiency.

[0096] During the rotation of the cutter, the rotary cutting part 31 can cut out the soil. The cut soil can move along the feeding part 32. The soil first moves to the material plate 33, and then rotates with the material plate 33. It is then pushed by the feeding plate 34, and the soil flies onto the baffle 15. It is then crushed by the crushing part 16. This breaks up the clumps of soil, making it easier to cover with fertilizer later.

[0097] Meanwhile, the trenching motor 12 will generate vibration during operation. The vibration is transmitted to the transmission rod 17, which in turn drives the baffle 15 to rotate. In this way, even if there are clumps of soil stuck between the crushing section 16, the clumps of soil can be further broken up by vibration, and the soil can be shaken off the baffle 15 by the vibration of the baffle 15.

[0098] During the vibration of the baffle 15, the elastic element 29 can be compressed, thereby causing the elastic element 29 to deform. The elastic element 29 can be a spring, which can increase the vibration frequency of the baffle 15, so that the baffle 15 can vibrate faster, thereby shaking the soil off the baffle 15 more quickly.

[0099] In summary, compared with existing technologies, it has the following beneficial effects:

[0100] The trenching motor 12 drives the cutter to rotate, which can cut the soil to open trenches. The excavated soil is scattered onto the baffle 15 and is crushed by the crushing part 16. This crushes the clumps of soil, so that when covering, the soil can be fully covered on the fertilizer, preventing the fertilizer from evaporating due to contact with the outside environment, and protecting the fertilizer so that its fertility can be fully absorbed by the soil.

[0101] The lifting drive assembly 20 can also drive the mounting plate 11 and the cutter to rise and fall, so that the depth of the trench can be adjusted as needed, and then fertilizer can be applied at a fixed depth to ensure that the fertilizer can better supplement the nutrients of the farmland.
