Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a corn protective field weed spraying device. Background Art

[0002] There are many weeds such as foxtail grass, gray grass, and amaranth in corn fields. These weeds will compete for the nutrition of corn during the growth of corn seedlings, causing the corn seedlings to be weak and thin in the early growth stage, which seriously affects the yield of corn. Therefore, it is necessary to weed the corn field. The cost of weeding before corn seedlings is lower than that of weeding after corn seedlings. The existing weeding methods are mostly spraying herbicides, and most herbicides can only be sprayed on the surface of the soil. Due to the limited amount of herbicides sprayed, the herbicides may not penetrate into the roots of the weeds, which leads to limited weeding effects.

[0003] To this end, a corn planting weed control spraying device with a bulletin number of "CN117256596A" includes a mounting plate, a first mounting rod is provided at the bottom of the mounting plate, a second mounting rod is provided at the bottom of the first mounting rod, a first rotating shaft and a trough are provided at both ends of the second mounting rod, and a plurality of sleeves are provided on the first rotating shaft. The shovel blade is inserted into the soil to loosen the soil and turn out the weeds. Secondly, the bucket can also rotate to dig up the soil turned out by the shovel blade. As the bucket rotates, the soil will fall into the trough. A spray head is provided on the trough to spray herbicides. A spiral blade is provided in the trough to push the soil to move and push out the soil sprayed with herbicides. The device can turn out the roots of weeds buried in the soil and then spray herbicides. Compared with the existing device, the herbicide can be fully contacted with the weeds, thereby improving the weed control effect.

[0004] However, for the above-mentioned corn planting weed control spraying device, although a plurality of buckets are provided, the buckets can rotate around the material trough, and the buckets can continuously dig the soil, thereby improving the efficiency of soil spraying, there are still the following obvious defects during use: the spraying method is only to spray the medicine on the soil collected in the material trough, and when the soil is scattered on the surface, most of the soil with the medicine liquid will not be attached to the surface of the soil, so that the problem of evaporation of the medicine liquid on the soil surface occurs when the sunlight is good, which will reduce the herbicidal effect of the medicine liquid.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a corn protective field weed spraying device, comprising:

[0024] A mounting frame 1, wherein a weeding roller 2 for weeding is rotatably provided on the inner side of the mounting frame 1, so that the weeding roller 2 can be mounted on agricultural equipment through the mounting frame 1 for weeding operations, a connecting drive seat connected to the agricultural equipment is provided at the end of the mounting frame 1, and a driving member 3 for driving the weeding roller 2 to rotate is provided on the outer side of the mounting frame 1, so that the weeding roller 2 can be driven to rotate, and the weeding member on the weeding roller 2 is rotated to weed the weeds on the soil surface, and a high-pressure liquid pump 4 is provided at the upper end of the mounting frame 1 for extracting and transporting liquid medicine to the high-pressure liquid pump, and a ring-shaped spraying mesh plate 10 is embedded on the surface of the weeding roller 2, so that the spraying member arranged inside the weeding roller 2 can be sprayed on the surface of the soil and the weeded weeds through the spraying mesh plate 10;

[0025] The bearing ring 5 is fixed at both ends of the inner cavity of the weeding roller 2, and the annular mounting member 7 can be fixed inside the bearing ring 5, so that when the weeding roller 2 rotates, the annular mounting member 7 will not rotate with it, and the inner ring of the bearing ring 5 is fixed with an annular mounting member 7, and the annular spraying pipe 6 can be installed inside the annular mounting member 7 to maintain a stable non-rotating state, so that multiple square boxes can be fixed for spraying. The annular spraying pipe 6 is installed inside the annular mounting member 7, which is conducive to the entry of the liquid medicine into the annular spraying pipe 6 and the delivery of the liquid medicine. To the inside of the three connected spraying transverse pipes 8, three horizontal spraying transverse pipes 8 are arranged between the bottom ends of one side of the annular spraying pipe fitting 6, which can transport the medicine in the spraying transverse pipes 8 to the high-pressure spraying pipe head 13, and pass through the spraying mesh plate 10 to be sprayed at high pressure on the soil that has not been turned over and on the weeds that have been eradicated on the soil surface. At the same time, the medicine sprayed on the soil surface can be kept inside when turning over the soil. One side of the annular spraying pipe fitting 6 on the inside of the weeding roller 2 is connected to the medicine main pipe 9, which can transport the medicine extracted by the high-pressure liquid pump 4 to the spraying pipe fitting inside the weeding roller 2.

[0026] A hollow rotating shaft rod 11 is penetrated through the middle of one end of the weeding roller 2, so that the medicine main pipe 9 can penetrate into the interior of the weeding roller 2 through the hollow structure inside the rotating shaft rod 11 and communicate with the annular spray pipe 6. The medicine main pipe 9 penetrates into the interior of the rotating shaft rod 11 and extends to the outside of one side of the mounting frame 1, so that one end of the medicine main pipe 9 can be connected to the output end of the high-pressure liquid pump 4 for conveying the medicine. The medicine inlet port of the high-pressure liquid pump 4 is connected to a medicine extraction pipe, and one end of the medicine extraction pipe is connected to a medicine tank 12 installed at the end of the mounting frame 1, so that the medicine in the medicine tank 12 can be extracted and conveyed to the spray pipe component inside the weeding roller 2, so that the medicine can be sprayed on the soil and weeds in the corn plant field, and the medicine output end of the high-pressure liquid pump 4 is connected to a medicine hose, and the other end of the medicine hose is connected to the medicine main pipe 9 outside one side of the mounting frame 1, which is conducive to spraying the output of the medicine.

[0027] The surface of the spraying transverse pipe 8 is evenly provided with high-pressure spraying pipe heads 13, and the liquid medicine transported to the spraying transverse pipe 8 can be sprayed out through the high-pressure spraying pipe head 13. One end of the high-pressure spraying pipe head 13 corresponds to the inner side of the spraying mesh plate 10 set on the weeding roller 2, which is conducive to the sprayed liquid medicine passing through the spraying mesh plate 10 and spraying on the soil and weeds. The surface of the weeding roller 2 and between the spraying mesh plate 10 are evenly provided with a shovel 14 for removing weeds in the corn field. The shovel 14 rotates with the weeding roller 2, and the shovel 14 rotates while the circular arc is inserted into the interior of the soil to turn over the soil and cover the liquid medicine sprayed on the soil surface with the interior of the soil, so as to prevent the liquid medicine from volatilizing and reducing the medicinal properties. The other end of the shovel 14 is provided with an arc-shaped weeding knife rod 15, so that the arc-shaped weeding knife rod 15 rotates and is inserted into the soil, and then continues to rotate and inserts into the roots of the weeds, and continues to rotate to dig out the weeds with the roots and expose them on the surface of the soil.

[0028] The driving component 3 includes a servo motor 16 fixed to the outside of the side plate of the mounting frame 1, which can drive the main driving teeth 17 to rotate to generate a meshing driving force on the auxiliary driving teeth 18. One end of the rotating shaft of the servo motor 16 is connected to the main driving teeth 17 for meshing driving. The rotation and meshing of the main driving teeth 17 drive the auxiliary driving teeth 18 to rotate. The rotating shaft of the other end of the weeding roller 2 passes through the outer side of the mounting frame 1 and is installed with the auxiliary driving teeth 18. The rotation of the auxiliary driving teeth 18 causes the weeding roller 2 to rotate. The auxiliary driving teeth 18 and the main driving teeth 17 on the servo motor 16 are connected to each other. The meshing drives the weeding roller 2 to rotate, and the rotation of the weeding roller 2 can drive the shovel blade 14 and the arc-shaped weeding knife rod 15 to rotate to turn up the soil and dig out the weeds. Cleaning support rods 19 are equidistantly provided on the inner side of the top plate of the mounting frame 1, and a wire brush 20 can be installed at the bottom of the cleaning support rod 19 to clean the surface of the weeding roller 2. The other end of the cleaning support rod 19 is provided with a wire brush 20, and the wire brush 20 is in contact with the surface of the spraying mesh plate 10 set on the surface of the weeding roller 2, so that the surface of the spraying mesh plate 10 that contacts the soil can be cleaned to avoid blocking the spraying of the medicine from the spraying mesh plate 10.

[0029] Specifically, when in use, the weeding roller 2 is first installed on the agricultural machinery equipment through the driving connecting seat on the mounting frame 1, and is protectively moved in the corn field. At the same time, the weeding roller 2 follows and rotates slowly, and the servo motor 16 is started to drive the main driving gear 17 to rotate. The main driving gear 17 engages to drive the auxiliary driving gear 18 to rotate, and the auxiliary driving gear 18 drives the weeding roller 2 to rotate through the shaft rod. The rotation of the weeding roller 2 is due to the hollow rotating shaft rod 11 at one end of the weeding roller 2, so that the medicine main pipe 9 inside its rotating shaft rod 11 does not follow the rotation and remains in a stationary state, and the outer ring of the bearing ring 5 arranged inside the weeding roller 2 follows and rotates. The rotation of the outer ring of the bearing ring 5 keeps the inner ring in a stationary state, so that the annular mounting member 7 in the inner ring of the bearing ring 5 can also remain in a stationary state, so that the annular spray pipe 6 inside the annular mounting member 7 does not follow the rotation of the weeding roller 2.

[0030] At this time, the rotation of the weeding roller 2 causes the shovel blade 14 to rotate and insert into the soil in the corn field, and insert into the soil in an arc shape and follow the circular rotation of the weeding roller 2 to turn over the soil, and at the same time, the arc-shaped weeding knife rod 15 rotates and inserts into the root and stem of the weeds in the soil, driving the weed roots to be dug out of the soil, so as to weed and turn the soil in the corn field. Prior to this, the high-pressure liquid pump 4 is started to extract the herbicide liquid in the liquid tank 12, and the extracted liquid is transported to the annular spray pipe 6 at one end of the weeding roller 2 through the liquid main pipe 9, and the liquid in the annular spray pipe 6 is transported to the spray cross pipe 8 in three directions arranged at the bottom end of the inner side of the weeding roller 2, and enters the spray cross pipe 8. The liquid medicine is sprayed out through the high-pressure medicine spraying pipe head 13 which is evenly arranged, and the sprayed liquid medicine passes through the multiple medicine spraying mesh plates 10 arranged on the weeding roller 2, so that the liquid medicine is sprayed on the surface of the soil that has not been turned over, the soil pits produced in the process of turning over the soil, and the surface of the dug weeds. In this way, the sprayed liquid medicine can be kept inside the soil after the soil that has not been turned over is turned over, and even if the sunlight is very good, the liquid medicine sprayed into the soil will not evaporate, and the medicinal property of the liquid medicine sprayed into the soil to kill weeds can be guaranteed. In order to prevent the medicine spraying mesh plate 10 from being blocked, the soil on the surface of the medicine spraying mesh plate 10 is cleaned by the wire brush 20 at the bottom of the cleaning support rod 19, so as to avoid the situation where the soil blocks the medicine spraying mesh plate 10 and the medicine liquid cannot be sprayed.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
