Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a clogging-proof fertilizer applicator. Background Technology

[0002] Fertilizer applicators are typically used to apply fertilizer evenly to soil or plants.

[0003] According to a public announcement (publication number: CN217037934U), a fertilizer applicator includes a vehicle body, a power rod rotatably mounted on a mounting plate, and a crankshaft mounted on the power rod; a guide block slidably mounted inside a trough, and a shovel rotatably mounted on the guide block, the top of which is rotatably connected to the crankshaft via a connecting rod; and an adjusting block slidably mounted inside the vehicle body, wherein the adjusting block cooperates with a discharge pipe, and when the guide block slides to the end of the trough, the discharge pipe is opened or closed.

[0004] In the aforementioned application, although the precise cooperation between the vehicle body and the feeding pipe assembly can effectively fertilize crops, it is impossible to prevent the feeding pipe from clogging during the fertilization process. The feeding pipe is prone to clogging, which will lead to uneven fertilization and affect the flow and distribution of fertilizer. Therefore, we propose an anti-clogging fertilization device. Utility Model Content

[0005] The purpose of this utility model is to provide a clogging-proof fertilization device. Through the design of components such as the air pump, T-junction, and airbag of the clogging-proof mechanism, the problem of easy clogging of fertilization pipes and poor fertilizer flow in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a clogging-proof fertilizer applicator, including a disc beam, a hopper fixedly connected to the top of the disc beam, a fertilizer applicator pipe fixedly passing through the bottom of the hopper, a moving wheel, a soil covering device and a trench opener provided at the bottom of the disc beam, a placement box fixedly connected to the top of the disc beam, and an anti-clogging mechanism provided at the top of the disc beam. The anti-clogging mechanism includes an air pump, which is fixedly connected to the top of the disc beam. A three-way pipe is fixedly connected to the output end of the air pump. An air blowing pipe is fixedly inserted through one end of the three-way pipe. The end of the air blowing pipe away from the three-way pipe is fixedly inserted through the circumference of the fertilizer pipe. A conveying pipe is fixedly inserted through the circumference of the air blowing pipe. An air bladder is fixedly inserted through the end of the conveying pipe away from the air blowing pipe. A material control plate is rotatably connected to the discharge port of the hopper. The purpose of this mechanism is to prevent blockage of the fertilizer pipe during use.

[0007] Furthermore, the anti-clogging mechanism is provided in two sets, and is symmetrical to each other along the vertical central axis of the beam. The purpose is to ensure that the fertilizer pipe at the bottom of each hopper can be effectively unblocked.

[0008] Furthermore, the bottom of the control plate is located on the displacement trajectory of the airbag, the purpose of which is to ensure that the airbag can push the control plate during the expansion process.

[0009] Furthermore, the air outlet of the air blowing pipe faces the bottom end of the fertilizer application pipe. The purpose of this is to ensure that during the fertilization process, the air blowing pipe can effectively blow away any clumps or impurities in the fertilizer through high-pressure airflow, preventing them from forming blockages in the fertilizer application pipe.

[0010] Furthermore, an adjustment mechanism is provided at one end of the fertilizer application tube. The adjustment mechanism includes a conical elastic rubber strip, which is fixedly connected to the end of the fertilizer application tube away from the fertilizer application tube. An adjustment nut is threaded onto the circumferential surface of the conical elastic rubber strip, the purpose of which is to adjust the size of the fertilizer application tube outlet.

[0011] Furthermore, the number of the conical elastic rubber strips is set to four, and they are arranged in a circumferential array along the circumference of the fertilizer tube. The purpose of this is to ensure that the four conical elastic rubber strips can form a sealed space.

[0012] Furthermore, the tapered elastic rubber strip has a taper of 1:5, the purpose of which is to enable the tapered elastic rubber strip to better adapt to the flow requirements of fertilizer in the fertilizer application pipe through a reasonable taper design.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes the cooperation between components such as the air pump, three-way pipe, and airbag in the anti-clogging mechanism. When the air pump of the anti-clogging mechanism is activated, the high-pressure airflow generated enters the blowing pipe through the three-way pipe and is sprayed along the bottom of the fertilizer pipe, blowing away fertilizer clumps and pipe wall residues to prevent blockage and ensure smooth fertilizer flow. The airflow further enters the airbag, pushing the control plate to swing, breaking up fertilizer accumulation at the hopper outlet, preventing caking and blockage, improving fertilization efficiency, and reducing equipment failure.

[0014] 2. This utility model utilizes the interaction between the conical elastic rubber strip and the adjusting nut assembly of the adjusting mechanism. Before fertilization, the user can adjust the size of the fertilizer pipe outlet by adjusting the adjusting nut. Rotating clockwise reduces the outlet diameter and fertilizer amount; rotating counterclockwise increases the diameter and fertilizer amount until the required discharge specifications are achieved, thus realizing precise fertilization and improving work efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model is a clogging-proof fertilizer applicator, including a disc beam 1, a hopper 2 fixedly connected to the top of the disc beam 1, a fertilizer pipe 3 fixedly passing through the bottom of the hopper 2, a moving wheel 4, a soil covering device 5 and a trench opener 6 provided at the bottom of the disc beam 1, a placement box 7 fixedly connected to the top of the disc beam 1, and an anti-clogging mechanism 8 provided at the top of the disc beam 1. The anti-clogging mechanism 8 includes an air pump 81, which is fixedly connected to the top of the disc beam 1. A three-way pipe 82 is fixedly connected to the output end of the air pump 81. An air blowing pipe 83 is fixedly passed through one end of the three-way pipe 82. The end of the air blowing pipe 83 away from the three-way pipe 82 is fixedly passed through the circumference of the fertilizer pipe 3. A conveying pipe 84 is fixedly passed through the circumference of the air blowing pipe 83. An air bag 85 is fixedly passed through the end of the conveying pipe 84 away from the air blowing pipe 83. A material control plate 86 is rotatably connected to the discharge port of the hopper 2. The purpose of this is to prevent the fertilizer pipe 3 from becoming clogged during use.

[0021] Two sets of anti-blocking mechanisms 8 are provided, and they are symmetrical to each other along the vertical central axis of the beam 1. The purpose is to ensure that the fertilizer pipe 3 at the bottom of each set of hoppers 2 can be effectively unblocked.

[0022] The bottom of the control plate 86 is located on the displacement trajectory of the airbag 85, the purpose of which is to ensure that the airbag 85 can push the control plate 86 during the expansion process.

[0023] The air outlet of the air blowing pipe 83 faces the bottom of the fertilizer pipe 3. The purpose is to ensure that during the fertilization process, the air blowing pipe 83 can effectively blow away the clumps or impurities in the fertilizer through high-pressure airflow, preventing them from forming blockages in the fertilizer pipe 3.

[0024] One end of the fertilizer pipe 3 is provided with an adjustment mechanism 9, which includes a tapered elastic rubber strip 91. The tapered elastic rubber strip 91 is fixedly connected to the end of the fertilizer pipe 3 away from the fertilizer pipe 3. An adjustment nut 92 is threadedly connected to the circumferential surface of the tapered elastic rubber strip 91. Its purpose is to adjust the size of the outlet of the fertilizer pipe 3.

[0025] Four tapered elastic rubber strips 91 are arranged in a circumferential array along the circumference of the fertilizer pipe 3, with the aim of ensuring that the four tapered elastic rubber strips 91 can form a sealed space.

[0026] The tapered elastic rubber strip 91 has a taper of 1:5. The purpose of this design is to allow the tapered elastic rubber strip 91 to better adapt to the flow requirements of fertilizer within the fertilizer application pipe 3.

[0027] A specific application of this embodiment is as follows: The air pump 81 of the anti-clogging mechanism 8 is activated. The high-pressure airflow generated by the air pump 81 enters the air blowing pipe 83 through the three-way pipe 82 at the output end. The airflow is transported to the fertilizer pipe 3 through the air blowing pipe 83. Since the air outlet of the air blowing pipe 83 faces the bottom of the fertilizer pipe 3, the high-pressure airflow is sprayed downward along the inner wall of the fertilizer pipe 3, which can directly blow away the clumps formed by the fertilizer during the transportation process. At the same time, it blows off the fertilizer residue attached to the pipe wall, avoiding the accumulation of impurities or clumps in the pipe and forming a blockage, ensuring that the fertilizer falls smoothly along the pipeline. The airflow inside the air blowing pipe 83 will form a second airflow through the conveying pipe 84. The second airflow is injected into the airbag 85 through the conveying pipe 84. The airbag 85 gradually expands under the action of the airflow. Since the bottom of the control plate 86 is located on the displacement trajectory of the airbag 85, the expanded airbag 85 will push the control plate 86 upward to swing. This swinging action can break the static accumulation of fertilizer at the outlet of the hopper 2 and prevent the fertilizer from caking and blocking at the hopper opening.

[0028] Before fertilization, the user can adjust the size of the fertilizer pipe 3 outlet by adjusting the adjusting nut 92 of the adjusting mechanism 9 according to the crop planting needs. When the adjusting nut 92 is rotated clockwise, the four conical elastic rubber strips 91 in a circular array contract inward, reducing the outlet diameter and the amount of fertilizer applied. When rotated counterclockwise, the rubber strips expand outward, increasing the outlet diameter and the amount of fertilizer applied, until the appropriate discharge specification is achieved. When the fertilizer reaches the bottom outlet of the fertilizer pipe 3 smoothly, the guide channel formed by the four conical elastic rubber strips 91 adapts to the fertilizer flow trajectory with a reasonable 1:5 taper design, reducing fertilizer adhesion. At the same time, the adjusted outlet diameter ensures that the fertilizer falls evenly into the fertilizer trench dug by the trench opener 6 according to the preset flow rate, achieving precise quantitative fertilization.
