Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural planting, and in particular relates to an agricultural wheat planting and fertilizing device. Background Art

[0002] Wheat is a general term for plants in the wheat family. It is a monocotyledonous plant and a grass plant widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods; after fermentation, it can be made into beer, alcohol, liquor, or biofuel. Wheat is the main food crop in my country; and the agricultural wheat planting and fertilization device is a special equipment used in the wheat planting process to achieve precise fertilizer delivery and efficient utilization through mechanical or intelligent methods. Its core goal is to improve fertilization efficiency, reduce resource waste, and promote the improvement of wheat yield and quality.

[0003] Currently, existing wheat planting and fertilization devices face some problems in actual use: the solid fertilizer poured into the fertilizer box is occasionally mixed with large lumps of fertilizer. These lumps can easily clog the outlet pipe when the fertilizer is discharged to the land, affecting the continuity and efficiency of the fertilization operation. More seriously, if the lumped fertilizer falls into the soil, after the wheat seeds are sown, the fertilizer will be over-concentrated and the concentration will be too high in the lumps, resulting in excessive fertilizer in the local soil, which will then cause seedling burn, damage the growth of wheat seedlings, reduce wheat yield and quality, and bring unnecessary losses to agricultural production. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes an agricultural wheat planting and fertilizing device to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

One of the crushing rollers is fixedly installed with the output end of a first motor and is driven to rotate by the first motor. A filter screen for screening fertilizer is movably installed inside the fertilizer box, and the lower end of the filter screen is in contact with the raised end of a cam, and the filter screen is driven to vibrate up and down by the rotation of the cam. The cam is fixedly installed on a rotating shaft, and the rotating shaft is rotatably installed inside the fertilizer box. The rotating shaft is connected to one of the gears through a transmission mechanism to achieve rotation of the rotating shaft driven by the rotation of the gear. A discharge port is provided below the fertilizer box, and the discharge port is connected to a distribution mechanism, and the distribution mechanism is used to distribute the fertilizer to the field.

[0007] Furthermore, the gear is rotatably mounted on the fertilizer box to ensure stable rotation of the gear. The first motor is fixedly mounted on the fertilizer box to provide stable power for the crushing roller. The filter is located below the two crushing rollers to screen the crushed fertilizer.

[0008] Furthermore, there are several cams, and the cams are all fixedly mounted on the rotating shaft to enhance the vibration effect on the filter screen. The transmission mechanism includes a first transmission wheel arranged on the rotating shaft, the first transmission wheel is fixedly mounted on the rotating shaft, the first transmission wheel is connected to the second transmission wheel through a transmission belt, and the second transmission wheel is fixedly mounted on one of the gears. The rotation of the gear drives the first transmission wheel and the second transmission wheel to rotate, thereby driving the rotating shaft to rotate.

[0009] Furthermore, a feed port is provided above the fertilizer box for adding fertilizer into the fertilizer box. The material distribution mechanism includes a connecting plate arranged below the fertilizer box, the connecting plate is fixedly mounted on the frame, the frame is fixedly mounted on the protective box, and the protective box is fixedly mounted on the mobile cart to facilitate the movement and operation of the entire device.

[0010] Furthermore, the connecting disk is connected to the discharge port to ensure that the fertilizer can enter the connecting disk smoothly. The connecting disk is provided with two discharge ports for spreading the fertilizer to both sides. A fertilizer rotating disk is rotatably installed below the discharge port to evenly spread the fertilizer. A lever is rotatably installed inside the connecting disk to control the discharge of the fertilizer. Fertilizer ports are provided on both sides of the frame to allow the fertilizer to be spread to the field.

[0011] Furthermore, the shift lever and the two fertilizer rotating disks are controlled by a linkage mechanism to achieve synchronous operation. The linkage mechanism includes a protective box arranged on the mobile cart, and a second motor is fixedly installed inside the protective box to provide power for the linkage mechanism. The output end of the second motor is fixedly installed with a first connecting shaft.

[0012] Furthermore, the first connecting shaft is fixedly mounted with a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is fixedly mounted on the shift rod, and the rotation of the first connecting shaft drives the shift rod to rotate, the first bevel gear is meshed with a third bevel gear, the third bevel gear is fixedly mounted on the second connecting shaft, the second connecting shaft is rotatably mounted inside the protective box, the second connecting shaft is fixedly mounted with a fourth bevel gear, the fourth bevel gear is meshed with a fifth bevel gear, the fifth bevel gear is fixedly mounted on the fertilizer rotating disk, and the rotation of the first connecting shaft drives the fertilizer rotating disk to rotate.

[0013] Furthermore, the fertilizer box is movably mounted on the base frame so that the height and angle of the fertilizer box can be adjusted, and the mobile cart is fixedly mounted with a handle to facilitate the operator to push the mobile cart for fertilizing operations.

[0014] The present invention has the following beneficial effects:

[0015] 1. The first motor drives two intermeshing gears to drive the crushing rollers to rotate synchronously in opposite directions, which can effectively squeeze and crush the block fertilizer; at the same time, the gear transmission drives the cam to rotate, causing the filter to vibrate periodically, which not only effectively prevents the mesh from being blocked, but also allows large particles of fertilizer that are not fully crushed to fall back for secondary crushing, ensuring that the fertilizer particles that finally enter the distribution mechanism are uniform and small, thereby improving the fertilizer quality and providing more suitable nutrients for wheat growth.

[0016] 2. The material distribution mechanism is rationally designed. The second motor drives the lever and the fertilizer rotating disc through a linkage mechanism to work in coordination. The lever evenly distributes the fertilizer in the connecting disc to the discharge port, and the fertilizer rotating disc then evenly spreads the fertilizer through the fertilizer port into the field. This achieves precise and uniform fertilizer distribution, avoids the problem of excessive or insufficient fertilizer in some areas due to uneven fertilization, and effectively improves fertilizer utilization and the overall fertilization effect of wheat planting.

[0017] 3. The device is installed on a mobile cart. The operator can easily push the device forward through the handle, which is convenient for flexible fertilization in different planting areas. At the same time, the fertilizer box can be adjusted in height along the base frame to ensure the consistency of fertilization depth according to actual planting conditions and fertilization needs, thereby enhancing the adaptability of the device to different planting environments and fertilization requirements, and improving the convenience and flexibility of fertilization operations.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0031] See also Figure 1-Figure 7 As shown, the present invention is a wheat planting fertilization device for agriculture, comprising a fertilizer box 1, within which two parallel grinding rollers 2 are rotatably mounted via bearings. Gears 4 are fixedly mounted at the ends of each grinding roller 2, and the two gears 4 mesh with each other, ensuring that the two grinding rollers 2 can rotate synchronously and in opposite directions. The output end of a first motor 3 is fixedly mounted to the shaft end of one of the grinding rollers 2 via a coupling, and the first motor 3 provides power to drive the grinding roller 2 to rotate.

[0032] A filter 5 is also movably mounted inside the fertilizer box 1, located below the two crushing rollers 2, to filter the crushed fertilizer. The lower end of the filter 5 engages with the raised end of a cam 6, which is fixedly mounted on a rotating shaft 7. The rotating shaft 7 is rotatably mounted inside the fertilizer box 1 via bearings and is connected to one of the gears 4 via a transmission mechanism to transmit power.

[0033] The operating principle of the agricultural wheat planting and fertilization device proposed in this invention is that when fertilizer is needed, an operator adds fertilizer to a fertilizer tank 1. After starting a first motor 3, the motor's output shaft rotates one of the crushing rollers 2. Because meshing gears 4 are fixedly mounted on the ends of the two crushing rollers 2, they rotate synchronously in opposite directions, creating a counter-extrusion effect that efficiently crushes fertilizer lumps into fine particles.

[0034] The crushed fertilizer naturally falls onto the tilted filter screen 5. Fertilizer particles that meet the required particle size fall through the mesh, while larger particles are intercepted and further crushed during the subsequent crushing process. Simultaneously, the rotation of one of the gears 4 is transmitted to the rotating shaft 7 via a transmission mechanism, causing the cam 6 fixed to the rotating shaft 7 to rotate synchronously. As the cam 6 rotates, its raised portion periodically lifts the filter screen 5, causing it to vibrate up and down. This effectively prevents fertilizer from clogging the mesh and encourages uncrushed fertilizer to fall back to the crushing roller 2 for secondary crushing.

[0035] After filtering, uniform fertilizer particles are discharged through outlet 8 at the bottom of fertilizer box 1 and enter the distributing mechanism. The distributing mechanism evenly distributes the fertilizer, ensuring uniform fertilization across the wheat planting area and improving fertilizer utilization. The entire process is continuous and efficient, achieving an integrated operation of crushing, screening, and fertilizing.

[0036] In one embodiment, for the above-mentioned gear 4, the gear 4 is rotatably mounted on the side wall of the fertilizer box 1 through a bearing to ensure the stability of rotation, and the first motor 3 is fixedly mounted on the outer wall of the fertilizer box 1 by bolts for easy maintenance and inspection, and is located directly below the two crushing rollers 2 to maximize the filtering effect.

[0037] In one embodiment, the aforementioned cams 6 are provided in multiple numbers, evenly distributed on the rotating shaft 7, to enhance the vibration effect on the filter 5. The transmission mechanism includes a first transmission wheel 9 disposed on the rotating shaft 7. The first transmission wheel 9 is fixedly mounted on the rotating shaft 7 via a key to ensure synchronous rotation. The first transmission wheel 9 is connected to a second transmission wheel 11 via a transmission belt 10. The second transmission wheel 11 is also fixedly mounted on one of the gears 4 via a key to achieve smooth power transmission.

[0038] The operating principle of the agricultural wheat planting fertilization device proposed in this invention is that after fertilizer is added to a fertilizer tank 1, a first motor 3 is activated, which drives one of the crushing rollers 2 to rotate via an output shaft. Because meshing gears 4 are fixedly mounted on the ends of both crushing rollers 2, and the gears 4 are rotatably mounted on the side walls of the fertilizer tank 1 via bearings, the two crushing rollers 2 rotate synchronously in opposite directions, effectively crushing the fertilizer.

[0039] The crushed fertilizer falls onto the inclined filter screen 5. Fine particles that meet the required particle size pass through the mesh and fall, while larger particles are intercepted. Simultaneously, the rotation of one of the gears 4 is transmitted to the rotating shaft 7 via the second transmission wheel 11, the transmission belt 10, and the first transmission wheel 9, driving the synchronous rotation of several cams 6 fixed to the rotating shaft 7. As the cams 6 rotate, their raised portions periodically lift the filter screen 5, causing it to continuously vibrate. This prevents clogging of the mesh and encourages any insufficiently crushed fertilizer to fall back to the crushing rollers 2 for secondary crushing.

[0040] The filtered uniform fertilizer particles are discharged from the discharge port 8 at the bottom of the fertilizer box 1 and enter the distribution mechanism to achieve uniform fertilization. The entire working process is continuous and stable, ensuring efficient coordination of fertilizer crushing, screening and spreading.

[0041] In one embodiment, the fertilizer box 1 has a feed port 12 formed on its top to facilitate the addition of fertilizer. A discharge port 8 is formed on its bottom, connected to a dispensing mechanism. The dispensing mechanism includes a connecting plate 13 disposed below the fertilizer box 1. The connecting plate 13 is bolted to a frame 14, which is in turn bolted to a protective box 15. The protective box 15 is further bolted to a mobile cart 16, forming a stable, integrated structure.

[0042] In one embodiment, the connecting disc 13 is interconnected with the discharge port 8, ensuring smooth access of fertilizer to the connecting disc 13. The connecting disc 13 has two discharge ports 17. A fertilizer rotating disc 19 is rotatably mounted below the discharge ports 17 on bearings, evenly distributing the fertilizer. A lever 20 is also rotatably mounted within the connecting disc 13 on bearings to assist in fertilizer distribution. Fertilizer ports 21 are located on both sides of the frame 14 to facilitate fertilizer discharge.

[0043] In one embodiment, the lever 20 and the two fertilizer rotating discs 19 are controlled by a linkage mechanism. The linkage mechanism includes a protective box 22 mounted on the mobile cart 16. A second motor 23 is fixedly mounted inside the protective box 22 via bolts. A first connecting shaft 24 is fixedly mounted to the output end of the second motor 23 via a coupling.

[0044] In one embodiment, for the above-mentioned first connecting shaft 24, the first connecting shaft 24 is fixedly mounted with a first bevel gear 25 via a key, the first bevel gear 25 is meshed with a second bevel gear 26, and the second bevel gear 26 is fixedly mounted on the shift lever 20 via a key to realize rotation control of the shift lever 20.

[0045] In one embodiment, the first bevel gear 25 is further engaged with a third bevel gear 27, which is keyed to a second connecting shaft 28. The second connecting shaft 28 is rotatably mounted within the protective housing 15 via a bearing to ensure rotational stability. A fourth bevel gear 29 is keyed to the second connecting shaft 28, which is engaged with a fifth bevel gear 30. The fifth bevel gear 30 is keyed to the fertilizer disc 19 to control the rotation of the fertilizer disc 19.

[0046] In one embodiment, the fertilizer box 1 is movably mounted on a base frame 31 via a slide rail, which facilitates adjustment of the height and position of the fertilizer box 1. The mobile cart 16 is fixedly provided with a handle 32, which facilitates the operator to push the device for mobile fertilization.

[0047] The operating principle of the agricultural wheat planting fertilization device proposed in this invention is that fertilizer is added through a feed port 12 above a fertilizer tank 1, and a first motor 3 drives a crushing roller 2. The two crushing rollers 2 rotate synchronously in opposite directions via intermeshing gears 4, crushing the fertilizer. The crushed fertilizer is sieved through a filter 5, and qualified particles enter a connecting disk 13 through a discharge port 8.

[0048] When the second motor 23 is activated, it rotates the first bevel gear 25 via the first connecting shaft 24. The first bevel gear 25 also drives the second and third bevel gears 26 and 27. The second bevel gear 26 rotates the lever 20, evenly distributing the fertilizer in the connecting disk 13 to the two discharge ports 17. The third bevel gear 27, driven by the second connecting shaft 28, the fourth bevel gear 29, and the fifth bevel gear 30, drives the two fertilizer rotating disks 19, evenly distributing the fertilizer through the fertilizer port 21 onto the field.

[0049] When the operator pushes the mobile cart 16 forward by the handle 32, the fertilizer box 1 can be adjusted in height along the base frame 31 to ensure the consistency of the fertilizer depth. The entire device realizes the synchronous operation of crushing, distributing and spreading through the linkage mechanism, completing the efficient and uniform fertilization process.
