Description

Technical Field

[0001] The invention relates to the field of fertilization, and more specifically, to a load-reducing fertilizer applicator which has no contact with cultivated land. Background Art

[0002] The fertilizer retention capacity and fertilizer supply characteristics of soils of different properties are also different; soils with heavy clay and high organic matter content have better fertilizer retention capacity, and there is no need to worry about nutrient loss when applying more fertilizer to this type of soil at one time; however, sandy soils have low fertilizer retention capacity, and small amounts of fertilizer should be applied multiple times to ensure full utilization of fertilizers and no waste; based on the crops grown, it is possible to analyze what kind of fertilizer the soil needs to ensure soil fertility.

[0003] There are many ways to apply fertilizer, such as basal fertilizer, topdressing, foliar fertilizer, hole fertilizer and base fertilizer. In the fertilization during the growth stage of crops, mechanical fertilization devices cannot enter the crops to perform precise positioning and fertilization. Although there are solutions to improve the above problems in the prior art, such as a Chinese patent for a fertilizer spreading fertilizer applicator and the technology with the authorization announcement number CN114982444B, it is provided that "fertilizer is spread through a spreading wheel device, and there is no need to enter the field for fertilization. Fertilizer can be spread on the ridge, which effectively reduces people's labor intensity and improves work efficiency"; however, when the spreading is applied to some plants with branches and leaves (such as seedlings, crops growing on trellises), the branches and leaves will form a certain obstruction to the spread fertilizer, so that the fertilizer cannot accurately fall near the plant roots to form effective fertilization.

[0004] Based on this, a load-reducing fertilizer applicator that does not contact the cultivated land is proposed to solve the problem that the mechanical fertilizer applicator cannot enter the crops to carry out precise positioning and fertilization during the fertilization in the growth stage of the crops. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art: during the fertilization of crops during the growth stage, mechanical fertilization devices cannot enter the crops to perform precise positioning and fertilization operations, and a load-reducing fertilizer applicator that does not contact the cultivated land is proposed.

The flexible conveying pipe fittings can adjust the fertilization coverage range by installing a plurality of unit conveying pipe fittings that are detachably assembled at the head and tail. At the same time, the conveying pipe uses a connecting pipe to drive the hollow ball for passing materials to rotate at multiple angles on the material guide head, and completes the angle rotation through the multi-angle adjustment head, so that the multi-angle adjustment head can adjust the rotation angle between multiple unit conveying pipe fittings, so that the flexible conveying pipe fittings can be adjusted into a variety of curved shapes to flexibly insert into the crop clusters blocked by branches and leaves, and accurately walk in the effective fertilization area near the crops. The storage box is placed outside the crop cluster, and the flexible conveying pipe fittings are adjusted into a variety of curved shapes to be flexibly inserted into the crop clusters, so as to realize precise positioning and fertilization on the basis of non-contact burden reduction of cultivated land.

[0007] In the detailed technical solution of the present invention, the unit conveying pipe also includes a vibrator, which includes a vibrating shell and two elastic positioning parts. The conveying pipe movably passes through the vibrating shell and is locked by two elastic positioning parts on both sides of the vibrating shell; a vibration motor is installed inside the vibration shell, and the vibration motor acts on the conveying pipe to vibrate the conveying pipe. The vibration motor transmits the vibration power source to the conveying pipe, and the conveying pipe will continue to vibrate the fertilizer inside the vibrator, so that the flexible conveying pipe can vibrate and disperse the fertilizer inside one part or multiple parts of multiple conveying pipes, so as to improve the uniformity of subsequent fertilization on the basis of improving the passing rate of the fertilizer by vibrating and dispersing the fertilizer.

[0008] Furthermore, the elastic mounting flange and the elastic positioning member adopt the same structure.

The material guide auger is connected to the conveying motor included in the conveying pipe by power transmission, and the conveying motor is installed outside the conveying pipe body. The vibration motor transmits the vibration power source to the conveying pipe, and the conveying pipe will continuously vibrate the fertilizer inside the vibrator. The agglomerated fertilizer will continuously hit the inner wall of the conveying pipe body and the material guide auger to be broken up, so that the flexible conveying pipe can vibrate and disperse the fertilizer inside one part or multiple parts of multiple conveying pipes, so as to improve the uniformity of subsequent fertilization on the basis of improving the passing rate of the fertilizer by vibrating and dispersing.

[0010] In the detailed technical solution of the present invention, the material storage box includes a material storage box body, a top cover is detachably installed on the top of the material storage box body, a plurality of supporting legs are installed at the bottom of the material storage box body, a material guide box is installed at the bottom of the material storage box body located on the inner side of the supporting legs, and a material discharge hole is opened on the material guide box, which is used for the installation of flexible conveying pipes.

[0011] In the detailed technical solution of the present invention, a shaking assembly is installed at the bottom of the storage box, and the shaking assembly includes a discharge barrel and a discharge auger. The discharge auger is rotatably assembled inside the discharge barrel to discharge the fertilizer inside the storage box and introduce it into the flexible conveying pipe.

[0012] Furthermore, the discharging auger includes a transmission shaft structure and a plurality of arc plates; the plurality of arc plates are spirally distributed on the transmission shaft structure in sequence to form a spiral pushing plate; the transmission shaft structure is used to drive the plurality of arc plates to rotate and push the material forward.

[0013] Furthermore, the transmission shaft structure includes a base plate and a plurality of support blocks, wherein the plurality of support blocks are distributed in a circular array on the base plate and form a cylindrical shape; the plurality of support blocks correspond to the plurality of arc plates one by one, and the arc plates are fixed on the side walls of the support blocks; the support blocks are slidably assembled on the base plate through pneumatic telescopic rods; and the plurality of support blocks are connected by elastic connecting belts. When the transmission shaft structure drives the plurality of arc plates that form a spiral push plate to rotate, a driving force is given to the fertilizer, prompting the fertilizer to move forward, and the fertilizer inside the storage box is discharged and introduced into the flexible conveying pipe; during the process of the arc plate rotating and pushing, the pneumatic telescopic rod is periodically started, prompting the support block to drive the arc plate to periodically reciprocate in the radial direction, so as to squeeze and break up the agglomerated fertilizer, improve the pass rate and quality of the fertilizer, and facilitate the uniformity of subsequent fertilization.

[0014] Furthermore, the shaking assembly also includes a plurality of extrusion abutment heads, which are distributed in a spiral array along the spiral gap of the discharging auger; the plurality of extrusion abutment heads are movably inserted into the discharging barrel; the discharging barrel includes an outer sleeve and an inner sleeve, and the inner sleeve is inserted and fixed inside the outer sleeve; a gap is reserved between the outer sleeve and the inner sleeve, the extrusion abutment heads are movably inserted into the tube wall of the inner sleeve, and the ends of the extrusion abutment heads are fixed on the inner wall of the outer sleeve.

During the process of the arc plate rotating and pushing materials, the hydraulic telescopic rod is started, and the hydraulic telescopic rod pushes the extrusion abutment plate into the spiral gap of the discharging auger. The fertilizer pushed by multiple arc plates will be squeezed onto the wedge-shaped surface of the extrusion abutment plate to break up the agglomerated fertilizer and improve the quality of fertilization; and during the periodic extension and retraction of the hydraulic telescopic rod, the extrusion abutment plate can be fully driven to mix and break up the fertilizer, and it can also be retracted in time when the fertilizer quality is high to improve the pass rate of the fertilizer; the extrusion abutment plate at the top of the wedge-shaped surface abuts against the bottom of the arc plate to clean the arc plate, improve the efficiency of the arc plate in pushing materials forward, avoid fertilizer residue, and avoid the pollution of subsequent replacement of other types of fertilizers for fertilization, avoiding the situation where unnecessary fertilizers appear in the application of different types of fertilizers at different times for crops, resulting in poor growth of crops.

[0016] Compared with the prior art, the load-reducing fertilizer applicator of the present invention which has no contact with the cultivated land can achieve the following: 1. Place a storage box containing fertilizers on the periphery of a crop cluster, and use a flexible conveying pipe to convey the fertilizers placed inside the storage box to the fertilization point. The flexible conveying pipe can adjust the coverage of fertilization by installing a plurality of unit conveying pipes that are detachably assembled at the head and tail. At the same time, the conveying pipe drives the hollow ball for passing materials to rotate at multiple angles on the material guide head by using a connecting pipe, and completes the angle rotation through the multi-angle adjustment head, so that the multi-angle adjustment head can adjust the rotation angles between the plurality of unit conveying pipes, and realize the flexible conveying pipe to be adjusted into a plurality of curved shapes, so as to flexibly insert the fertilizers into the crop clusters blocked by branches and leaves, and accurately walk in the effective fertilization area near the crops. The storage box is placed on the periphery of the crop cluster, and the flexible conveying pipe is adjusted into a plurality of curved shapes and flexibly inserted into the crop clusters, so as to realize the precise positioning operation and fertilization on the basis of non-contact burden reduction of the cultivated land. Second, when some granular fertilizers are poured from sealed bags and are in contact with humid air during fertilization, especially on rainy days with high humidity, there is a risk that the fertilizers will clump, causing blockage of the fertilization mechanism and uneven fertilization. Start the vibration motor, which transmits the vibration power source to the conveying pipe. The conveying pipe will continuously vibrate the fertilizer inside the vibrator. The clumped fertilizers will continuously hit the inner wall of the conveying pipe and the guide auger to break them up. The flexible conveying pipe can vibrate and disperse the fertilizers in one or more parts of the conveying pipes, so as to improve the uniformity of subsequent fertilization on the basis of improving the passing rate of the fertilizers by vibrating them. 3. When the transmission shaft structure drives multiple arc plates in the shape of spiral pusher plates to rotate, it will give the fertilizer a driving force, prompting the fertilizer to move forward, complete the extraction of the fertilizer inside the storage box, and introduce it into the flexible conveying pipe; during the arc plate rotation and pushing process, the pneumatic telescopic rod is periodically started to prompt the support block to drive the arc plate to periodically reciprocate in the radial direction, so as to squeeze and break up the agglomerated fertilizer, improve the pass rate and quality of the fertilizer, and facilitate the uniformity of subsequent fertilization; 4. During the process of the arc plate rotating and pushing materials, the hydraulic telescopic rod is started, and the hydraulic telescopic rod pushes the extrusion plate into the spiral gap of the discharging auger. The fertilizer pushed by multiple arc plates will be squeezed onto the wedge surface of the extrusion plate to break up the agglomerated fertilizer and improve the quality of fertilization. During the periodic expansion and contraction of the hydraulic telescopic rod, the extrusion plate can be fully driven to mix and break up the fertilizer, and it can also be retracted in time when the fertilizer quality is high, so as to improve the passing rate of the fertilizer. 5. The extrusion abutment plate at the top of the wedge-shaped surface abuts against the bottom of the arc plate to clean the arc plate, improve the efficiency of the arc plate in pushing materials forward, avoid fertilizer residue, and prevent pollution to subsequent fertilization by replacing other types of fertilizers, thus avoiding the situation in which unnecessary fertilizers appear in the application of different types of fertilizers at different times for crops, resulting in poor growth of crops.

[0037] Therefore, during the process of the arc plate 820 rotating and pushing the material, the hydraulic telescopic rod 910 is started, and the hydraulic telescopic rod 910 pushes the extrusion abutment plate 920 into the spiral gap of the discharging auger 800, and the fertilizer pushed by the multiple arc plates 820 will be squeezed onto the wedge surface 930 of the extrusion abutment plate 920, breaking up the agglomerated fertilizer and improving the quality of fertilization; and during the periodic expansion and contraction of the hydraulic telescopic rod 910, the extrusion abutment plate 920 can be fully driven to mix and break up the fertilizer, and it can also be retracted in time when the fertilizer quality is high, thereby improving the passing rate of the fertilizer; At the same time, the extrusion abutment plate 920 at the top of the wedge surface 930 abuts against the bottom of the arc plate 820, thereby cleaning the arc plate 820, improving the efficiency of the arc plate 820 in pushing the material forward, avoiding fertilizer residue, and pollution to subsequent fertilization by replacing other types of fertilizers, thereby avoiding the situation in which unnecessary fertilizers appear in the application of different types of fertilizers to crops at different times, causing poor growth of crops.
