Technical Field

[0001] This utility model relates to the field of soil conditioner application, and in particular to a soil conditioner application device. Background Technology

[0002] Soil conditioners are substances or materials used to improve the physical, chemical, or biological properties of soil, thereby enhancing soil quality and promoting plant growth. They help soil regain its health and adapt to the growth needs of different plants by adjusting soil structure, increasing nutrients, regulating pH, or remediating pollution. Currently, when spreading lime into the soil to adjust acidic soil, a specialized lime spreading machine is generally used.

[0003] Traditional lime spreaders still have certain shortcomings in actual use: Current lime spreaders are generally mounted at the rear of agricultural vehicles, and the bottom of the spreader has several lime outlets. When the vehicle moves forward, the lime is easily thrown up, causing the area above the machine and the surrounding roads in farmland, orchards to be covered with lime, which causes great disturbance to people in the vicinity. The traditional structural design is not reasonable enough, and there is a lack of a dust-proof component that can significantly reduce the degree of lime being thrown up, while being easy to maintain and replace.

[0004] Therefore, it is necessary to provide a new soil conditioner application device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a soil conditioner application device that can significantly reduce lime dusting, has a convenient structure for maintenance and replacement, and can be folded when not in use.

[0007] The left and right side walls of the cover are symmetrically provided with threaded holes. The surface of the fastener is provided with mounting holes corresponding to the threaded holes. A locking bolt is inserted through the inner side of the mounting hole. The locking bolt and the mounting hole are in clearance fit and the locking bolt and the threaded hole are in thread fit. A dustproof cloth is provided in the gap between the cover and the fastener.

[0008] As a further embodiment of this utility model, a bottom hopper is fixedly connected to the bottom of the storage bin, the bottom inner wall of the bottom hopper is set as an arc-shaped surface, a scraper is provided on the inner side of the bottom hopper, and the two ends of the scraper are rotatably connected to the left and right side wall surfaces of the bottom hopper.

[0009] With the above technical solution, when the first and second through holes are connected, the user starts the drive motor and uses the pulley belt transmission structure to drive the scraper to rotate, so that the blades on the scraper will move the lime in the storage bin to the bottom of the bottom hopper and through the first and second through holes, falling onto the soil.

[0010] As a further embodiment of this utility model, a protective shell is fixedly connected to one side of the outer wall surface of the bottom hopper, one end of the scraper extends into the interior of the protective shell and is fixedly connected to a large pulley, a drive motor is fixedly connected to the outer surface of the protective shell away from the large pulley, the output end of the drive motor passes through the side wall of the protective shell and is fixedly connected to a small pulley, the small pulley is located inside the protective shell and is meshed with the large pulley by a belt surrounding its outer circumference.

[0011] The above technical solution, by setting up a drive motor and a pulley belt transmission structure, allows the scraper in the bottom hopper to rotate and stir the lime after the worker turns on the drive motor.

[0012] As a further embodiment of this utility model, a movable component is provided at the lower side of the bottom hopper, the upper surface of the movable component is in contact with the bottom surface of the bottom hopper, and the bottom of the bottom hopper is provided with a plurality of equally spaced through holes I, and the surface of the movable component located below the through holes is provided with through holes II.

[0013] With the above technical solution, once the connection between through hole one and through hole two is achieved, the lime in the bottom hopper will pass through the two holes and fall onto the soil below.

[0014] As a further embodiment of this utility model, the movable part is slidably connected to the outer surface of the bottom hopper, and an electric telescopic rod II is fixedly connected to one side of the outer wall surface of the bottom hopper, with the telescopic end of the electric telescopic rod II being fixedly connected to the movable part.

[0015] Through the above technical solution, the position of the movable part can be adjusted, thereby adjusting the size of the part connecting the second through hole and the first through hole above, and thus adjusting the amount of lime falling.

[0016] As a further embodiment of this utility model, a top connecting shaft is fixedly connected to the outer surface of the storage compartment on one side relative to the electric telescopic rod, and bottom connecting shafts are fixedly connected symmetrically on the surface of the storage compartment located below the top connecting shaft. The top of the storage compartment is set as an opening.

[0017] The above technical solution allows for the overall fixation of agricultural power equipment by installing hooks at the rear of the top and bottom connecting shafts.

[0018] Compared with related technologies, the soil conditioner application device provided by this utility model has the following beneficial effects:

[0019] The device features a dust-covering structure on one side of the ash spreader, including a cover. The cover is hinged to the recessed part of the storage bin via an electric telescopic rod. When the user does not need the cover, it can be rotated and folded to avoid occupying too much storage space. At this time, the inner surface of the cover faces one side, making it convenient for the user to clean the lime powder and other impurities on the inner wall of the cover. The structure is reasonably designed. When the cover is in normal use, the dust-covering cloth fixed at its bottom edge can contact the soil surface. As the agricultural machinery moves the storage bin forward, most of the lime powder that is raised will enter the inner side of the cover. Due to the obstruction of the dust-covering cloth, the lime is effectively suppressed, greatly reducing the amount of lime powder flying to the outside. The dust-covering cloth is clamped to the outer surface of the cover by a fixing device. When the dust-covering cloth is worn, the user can remove it in time to replace it. The structural design facilitates user maintenance or replacement. Attached Figure Description

Figure 1 ; Figure 3 This is a partial structural breakdown diagram of a soil conditioner application device according to the present invention;

[0028] Figure 4 This is a partial structural cross-section of a soil conditioner application device according to the present invention. Figure 2 A soil conditioner application device includes:

[0029] The ash spreading machine body 1 includes a storage bin 13. A dust-proof structure 2 is installed on the surface of the storage bin 13. An indentation 3 is provided on the front wall surface of the storage bin 13. The dust-proof structure 2 includes a side connector 4. The side connector 4 is fixedly connected to the surface of the storage bin 13 on the lower side of the indentation 3. A cover 14 is hinged to the bottom of the side connector 4. An electric telescopic rod 5 is hinged between the surface of the storage bin 13 located at the indentation 3 and the top of the cover 14. Several equally spaced and evenly arranged locking teeth 15 are fixedly connected to the left and right side wall surfaces and the front wall surface of the cover 14. A fixing member 19 is provided on the outer side of the cover 14. The surface of the fixing member 19 facing the locking teeth 15 is provided with a slot 20 corresponding to the locking teeth 15.

[0030] The left and right side walls of the cover 14 are symmetrically provided with threaded holes 16. The surface of the fastener 19 is provided with mounting holes 18 corresponding to the threaded holes 16. A locking bolt 17 is provided inside the mounting hole 18. The locking bolt 17 and the mounting hole 18 are in clearance fit, and the locking bolt 17 and the threaded hole 16 are in thread fit. A dust cover 11 is provided in the gap between the cover 14 and the fastener 19.

[0031] like Figure 1-4 As shown, a bottom hopper 22 is fixedly connected to the bottom of the storage bin 13. The bottom inner wall of the bottom hopper 22 is set as an arc-shaped surface 23. A scraper 21 is provided on the inner side of the bottom hopper 22. The two ends of the scraper 21 are rotatably connected to the left and right side wall surfaces of the bottom hopper 22.

[0032] When the first through hole 24 and the second through hole 25 are connected, the user starts the drive motor 8, which uses the pulley belt transmission structure to drive the scraper 21 to rotate. This causes the blades on the scraper 21 to move the lime in the storage bin 13 to the bottom of the bottom hopper 22 and through the first through hole 24 and the second through hole 25, and fall onto the soil.

[0033] like Figure 1-4 As shown, a protective shell is fixedly connected to one side of the outer wall surface of the bottom hopper 22. One end of the scraper 21 extends into the interior of the protective shell and is fixedly connected to a large pulley 10. A drive motor 8 is fixedly connected to the outer surface of the protective shell away from the large pulley 10. The output end of the drive motor 8 passes through the side wall of the protective shell and is fixedly connected to a small pulley 9. The small pulley 9 is located inside the protective shell and is meshed with the large pulley 10 by a belt around its outer circumference.

[0034] By setting up a drive motor 8 and a pulley belt transmission structure, the scraper 21 in the bottom hopper 22 can rotate and stir the lime after the worker turns on the drive motor 8.

[0035] like Figure 1-4 As shown, a movable part 26 is provided on the lower side of the bottom hopper 22. The upper surface of the movable part 26 is in contact with the bottom surface of the bottom hopper 22. The bottom of the bottom hopper 22 has several through holes 1 24 that are evenly distributed at equal intervals. A through hole 25 is provided on the surface of the movable part 26 located below the through holes 1 24.

[0036] Once the connection between hole 1 (24) and hole 2 (25) is established, the lime in the bottom hopper 22 will pass through the two holes and fall onto the soil below.

[0037] like Figure 1-4 As shown, the movable part 26 is slidably connected to the outer surface of the bottom hopper 22, and an electric telescopic rod 12 is fixedly connected to one side of the outer wall surface of the bottom hopper 22. The telescopic end of the electric telescopic rod 12 is fixedly connected to the movable part 26.

[0038] The position of the movable part 26 can be adjusted to adjust the size of the part connecting the second through hole 25 and the first through hole 24 above, thereby adjusting the amount of lime falling.

[0039] like Figure 1-4As shown, a top connecting shaft 7 is fixedly connected to the outer surface of the storage compartment 13 on the side of the electric telescopic rod 5, and a bottom connecting shaft 6 is fixedly connected symmetrically on the surface of the storage compartment 13 located below the top connecting shaft 7. The top of the storage compartment 13 is set as an opening.

[0040] The entire device can be fixed by installing hooks at the rear of the agricultural power equipment that match the top connecting shaft 7 and the bottom connecting shaft 6.

[0041] The working principle of the soil conditioner application device provided by this utility model is as follows:

[0042] The device adds a dust-covering structure 2 to one side of the ash spreader body 1, including a cover 14. The cover 14 is hinged to the inner recess 3 of the storage bin 13 via an electric telescopic rod 5. When the user does not need to use the cover 14, it can be rotated and folded to avoid the cover 14 occupying too much storage space. At this time, the inner surface of the cover 14 faces one side, which is convenient for the user to clean the lime powder and other impurities on the inner wall of the cover 14. The structure design is reasonable. When the cover 14 is in normal use, the dust-covering cloth 11 fixed at its bottom edge can contact the soil surface. As the agricultural machinery moves the storage bin forward, most of the lime powder will enter the inner side of the cover 14. Due to the obstruction of the dust-covering cloth 11, the lime is effectively suppressed, greatly reducing the amount of lime powder flying to the outside. The dust-covering cloth 11 is clamped on the outer surface of the cover 14 by the fixing part 19. When the dust-covering cloth 11 is worn, the user can disassemble it in time to replace it. The structure design is convenient for users to maintain or replace.
