Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery operation equipment technology, specifically an automatic ash spreading equipment for corn experimental fields based on dual-track drive. Background Technology

[0002] The maize experimental field is an important carrier for agricultural scientific research and technology promotion. Through centralized planting, scientific management and comparative experiments, it explores the adaptability and high-yield potential of new maize varieties, planting techniques and management models. Its core value lies in verifying the achievements of agricultural scientific and technological innovation, providing replicable experience for large-scale production, and promoting the transformation of traditional agriculture towards modernization and precision. In the maize experimental field, the straight marking of the planting path by spreading lime is an important preparatory work. It helps to ensure the accuracy and uniformity of the planting path, thereby improving the growth efficiency and yield of crops.

[0003] Currently, corn experimental fields typically undertake precision agriculture research tasks such as variety selection, fertilization effectiveness, and pest and disease control, which have high requirements for operational accuracy and data recording. Traditional wheeled ash spreading equipment cannot cope with the uneven field conditions of corn experimental fields. When marking lines for ash spreading, it is easy to become skewed, which makes it impossible for the ash spreading equipment to spread ash and arrange the paths accurately in the corn experimental fields, affecting the results of later experiments. Furthermore, when marking lines with lime, the material is usually replenished manually, which results in high labor intensity during the operation and is not conducive to the continuous operation of the ash spreading equipment.

[0015] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0016] 1. The agricultural machinery chassis drives the connecting frame and the lime-spreading funnel to move. The chassis is driven by double moving tracks on both sides, allowing for stable movement in uneven, ditched fields. This ensures the accuracy of the lime-spreading lines. By filling the lime-spreading funnel with lime, the funnel moves with the machinery during its movement. The distance between the centers of the two funnels is adjusted to one meter, facilitating the spread of lime in one-meter channels. The height of the flexible material-leaching hose at the bottom of the funnel is five centimeters above the ground, allowing for straight lime application into the ground without overflowing. This ensures precise straight-line marking of the channels, resulting in more accurate and neat subsequent sowing paths.

The lime storage box is used to conveniently store lime powder. Combined with the negative pressure conveying pipe and the centralized hopper, the axial flow fan and the lime storage box are connected. With the help of the air box, after the axial flow fan is started, the lime powder in the lime storage box can be quickly transported to the ash-spreading funnel based on the negative pressure. This facilitates the rapid replenishment of lime stored in the lime storage box to the ash-spreading funnel, reducing the labor intensity of manual replenishment. At the same time, it realizes automatic replenishment and avoids frequent replenishment from affecting the continuous operation of agricultural machinery.

[0018] 3. The fixed base facilitates quick and stable connection and installation between the end of the connecting frame and the chassis of the agricultural machinery. At the same time, the telescopic support rod inside the connecting frame allows for easy adjustment of the position of the connecting base and the ash-spreading funnel. Multiple positioning holes facilitate adjustment of different spacings, so that the spacing between the two ash-spreading funnels can meet the usage requirements of different width channels. Through the limiting connection between the positioning bolt and the standard hole, the distance between the center points of the two ash-spreading funnels can be quickly adjusted to one meter, thus facilitating the rapid ash-spreading use of a one-meter channel.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figure 1-4 As shown, this utility model provides a technical solution: an automatic ash spreading equipment for corn experimental fields based on dual-track drive, including an agricultural machinery chassis 1. An engine 2 is fixedly installed on one side of the top of the agricultural machinery chassis 1, and a mobile power supply box 3 is fixedly installed on one side of the engine 2. An oil tank 4 is fixedly installed on the same side of the engine 2 and the mobile power supply box 3. A crash barrier 5 is fixedly installed in the middle of the forward end of the agricultural machinery chassis 1, and mobile tracks 6 are installed on both sides of the bottom of the agricultural machinery chassis 1. The power input end of the mobile track 6 is connected to the power output end of the engine 2, and the engine 2 drives the mobile track 6 to move. The input end of the axial flow fan 13 is electrically connected to the output end of the mobile power supply inside the mobile power supply box 3, which facilitates the movement of the agricultural machinery equipment through the mobile track 6. The dual mobile tracks 6 can move stably in uneven fields with ditches, thereby ensuring the accuracy of the ash spreading equipment in actual ash spreading and line drawing. A control lever 7 is connected to the other side of the agricultural machinery chassis 1 corresponding to the crash barrier 5.

[0028] The top of the agricultural machinery chassis 1 is detachably connected to the connecting frame 8 on both sides of the oil tank 4. The adjustable end of the connecting frame 8 is fixedly connected to the ash-spreading funnel 10. The bottom discharge end of the ash-spreading funnel 10 is connected to the material-leaking hose 11. The top edge of the ash-spreading funnel 10 is fixedly connected to the connecting plate 12. The bottom of the ash-spreading funnel 10 is equipped with a solenoid valve, which is connected to the top of the material-leaking hose 11. The connecting plate 12 is fixedly connected to the ash-spreading funnel 10 by screws. The bottom of the connecting plate 12 is provided with a sealing ring, which facilitates the opening and closing control of the material-leaking hose 11 by the solenoid valve. It also facilitates the connection between the connecting plate 12 and the ash-spreading funnel 10. When the lime powder inside the ash-spreading funnel 10 is insufficient, it is convenient to replenish the lime powder into the ash-spreading funnel 10. The ash-spreading funnel 10 is fixedly connected to the axial flow fan 13 through the connecting plate 12 on its top. The top air inlet end of the axial flow fan 13 is connected to the negative pressure conveying pipe 14.

[0029] A lime storage box 15 is fixedly placed on the top of the agricultural machinery chassis 1, next to the engine 2 and the mobile power supply box 3. The input end of the negative pressure conveying pipe 14 is connected to the discharge end of the top of the lime storage box 15. Concentrated buckets 16 are installed at the connection points between the negative pressure conveying pipe 14 and the axial flow fan 13 and the lime storage box 15. An air box 17 is provided on the side of the lime storage box 15. The air box 17 is filled with filter cotton and is connected to the inside of the lime storage box 15. A sealing cover is detachably connected to the top of the lime storage box 15 to facilitate the intake of air into the lime storage box 15. Based on the negative pressure, the lime powder in the lime storage box 15 is quickly transported to the lime spreading funnel 10.

[0030] The inner side of the connecting frame 8 is telescopically connected to a telescopic support rod 18, and the end of the connecting frame 8 is detachably connected to the agricultural machinery equipment chassis 1 via a fixing seat 9. The telescopic support rod 18 is fixedly connected to the outer wall of the ash spreading funnel 10 via the connecting seat 19 connected to its end.

[0031] The top of the telescopic support rod 18 is provided with positioning holes 20 at equal intervals, and the top of the connecting frame 8 is connected with positioning bolts 21 corresponding to the positioning holes 20. After the positioning bolts 21 are connected to the standard holes, the distance between the center points of the two ash-spreading funnels 10 is one meter. The bottom end of the material-spreading hose 11 at the bottom of the ash-spreading funnel 10 is five centimeters away from the ground. Through the limiting connection between the positioning bolts 21 and the standard holes, the distance between the center points of the two ash-spreading funnels 10 can be quickly adjusted to one meter, which is convenient for the rapid ash-spreading of the one-meter channel. The fixed seat 9 is detachably connected to the agricultural machinery equipment chassis 1 by bolts. The positioning hole 20 at the top of the telescopic support rod 18 that is farthest from the ash-spreading funnel 10 is the standard hole. The positioning bolts 21 are connected to the positioning holes 20 and the standard holes by threads, which is convenient for the quick and stable connection and installation of the end of the connecting frame 8 to the agricultural machinery equipment chassis 1. At the same time, the telescopic support rod 18 on the inside of the connecting frame 8 can be used to adjust the position of the connecting seat 19 and the ash-spreading funnel 10.

[0032] The working principle and usage process of this utility model: In actual application, the automatic ash spreading equipment for corn experimental fields based on dual track drive uses oil tank 4 to supply oil to engine 2 and mobile power supply box 3 to provide power. Engine 2 drives the mobile track 6 to move, and the mobile track 6 drives the agricultural machinery chassis 1 to move. In this way, driven by dual mobile track 6, it can move stably in uneven fields with ditches, ensuring the accuracy of the subsequent actual ash spreading and line drawing process.

[0033] The end of the connecting frame 8 is quickly and stably connected to the agricultural machinery chassis 1 by the fixing seat 9. At the same time, the position of the connecting seat 19 and the ash spreading funnel 10 is adjusted by the telescopic support rod 18 on the inner side of the connecting frame 8. The multiple positioning holes 20 are used to easily adjust different spacings so that the spacing between the two ash spreading funnels 10 can meet the usage requirements of different width channels. The positioning bolt 21 and the standard hole limit connection can be adjusted to quickly make the spacing between the center points of the two ash spreading funnels 10 one meter, so as to facilitate the rapid ash spreading of one-meter channels.

[0034] Before spreading lime, it is necessary to ensure that the lime spreading funnel 10 is filled with lime. When it is necessary to replenish the lime powder in the lime storage box 15 into the lime spreading funnel 10, the axial flow fan 13 is integrated and connected to the top of the lime spreading funnel 10 through the connecting plate 12. The axial flow fan 13 and the lime storage box 15 are connected by the negative pressure conveying pipe 14 and the centralized hopper 16. With the help of the air box 17, after the axial flow fan 13 is started, the lime powder in the lime storage box 15 can be quickly transported into the lime spreading funnel 10 based on the negative pressure. This facilitates the quick replenishment of the lime stored in the lime storage box 15 into the lime spreading funnel 10, reduces the labor intensity of manual replenishment, and realizes automatic replenishment, avoiding frequent replenishment from affecting the continuous operation of agricultural machinery.

[0035] Finally, during the actual process of spreading lime and marking the path, the lime spreading funnel 10 is moved and spread as the agricultural machinery moves. The distance between the centers of the two lime spreading funnels 10 is one meter, which facilitates the use of lime spreading for a one-meter path. The height of the material leakage hose 11 at the bottom of the lime spreading funnel 10 is five centimeters from the ground. The lime is then spread into the ground in a straight line through the material leakage hose 11 to avoid lime overflow, thus achieving precise straight line marking of the path and ensuring that the subsequent sowing path is more accurate and neat. In addition, during the actual operation of marking the path, the straight line marking of the path can also be completed by remote control or by setting an automatic positioning program. It can also be turned around and switched to another path as needed.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
