Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an agricultural fertilizer spreading device. Background Art

[0002] In the process of crop planting, fertilization is required to ensure the nutrients required for crop growth. Fertilizers are applied to the soil or spread on crops to improve the quality of crops and increase crop yields. At present, fertilization mainly relies on manual fertilization by personnel or the use of fertilizer spreading equipment. Manual fertilization is inefficient and labor-intensive. Fertilizer spreading equipment is mostly large-scale equipment and has poor applicability to areas with less arable land. Therefore, in order to cope with the above problems, a Chinese patent No. CN218649268U discloses an efficient and uniform fertilizer spreading vehicle, which drives a throwing plate 20 to rotate through a driving motor 18. The fertilizer on the surface of the throwing plate 20 will be thrown out along the side wall of the partition 21 due to the centrifugal force, so that automatic fertilizer spreading can be achieved. However, during use, a driving motor is required to drive the throwing plate to rotate, and external power is required to achieve spreading. In addition, the need for power makes the spreading port more complicated and the overall equipment heavier. Secondly, only the spreading range can be adjusted, but the amount of material discharged cannot be adjusted, and it cannot be adjusted according to the actual needs of the arable land.

[0030] Example

[0031] As mentioned in the background technology, fertilization is required during the crop planting process. The existing fertilization technologies are mostly manual fertilization or the use of larger fertilization equipment. However, the above methods have many disadvantages. The fertilization speed is too low and the labor intensity is high, or it is not suitable for small-scale spreading work. Although the fertilizer spreading vehicle in the existing patent can overcome the above problems to a certain extent, it requires more power equipment in actual use, which is more energy-wasting and has a more complicated structure and lower practicality. Therefore, the inventor has made improvements on the existing fertilization equipment and designed a new fertilization device, which is described in detail below with reference to the drawings.

[0032] This embodiment provides an agricultural fertilizer spreading device, see Figure 1 , including two inclined push rods 1, the two push rods 1 are arranged in parallel along a direction perpendicular to the overall movement, the upper ends of the push rods 1 are bent downward for the convenience of the user to hold them, a rotating shaft 2 runs through the bottom ends of the two push rods 1 and is rotatably connected, a sheet plate can be connected to the bottom end of the push rod 1, the rotating shaft 2 runs through the sheet plate and is rotatably connected, and for the convenience of movement, moving wheels 3 are connected at both ends of the rotating shaft 2, the rotating shaft 2 can rotate along with the moving wheels 3, and the entire fertilizer spreading device can be moved by pushing the push rods 1.

[0033] In order to support the entire fertilizer spreading device on the ground during non-seeding time, studs 17 are provided on the opposite sides of the two push rods 1, and a bracket 18 is connected through the studs 17. The bracket 18 can slide along the studs 17 in a direction away from the push rod 1. The studs 17 are non-threaded and protrude from the push rod 1 to facilitate the sliding of the bracket 18, and the upper end of the bracket 18 is plugged into the push rod 1, and a plug post 19 is provided on the side of the bracket 18 close to the push rod 1. A socket 20 is provided at the corresponding position of the push rod 1, and the length of the plug post 19 is less than the length of the stud 17 protruding from the push rod 1, so as to ensure that the plug post 19 can completely leave the socket 20. The length of the bracket 18 ensures that when the plug post 19 leaves the socket 20, it can be supported on the ground by rotating downward. When it needs to be supported on the ground, the bracket 18 is slid outward, the plug post 19 leaves the socket 20, and the upper end rotates downward around the stud 17, and one end of the plug post 19 is supported on the ground.

[0034] Based on the above structure, combined with Figure 2 The specific design of the fertilizer spreading component is that a support seat 4 is installed between the two hand push rods 1, and the support seat 4 is set in a plate shape. One end of the support seat 4 can be fixed between the two hand push rods 1 by welding, and is in the middle position of the entire hand push rod 1, and is set horizontally higher than the moving wheel 3, and extends to one side in the direction of the moving wheel 3, providing a larger space for installing a material throwing piece below. In order to store fertilizer, a storage barrel 5 is arranged on the support seat 4, and a discharge port 6 is opened at the bottom of the storage barrel 5 and the corresponding support seat 4. The positions of the discharge port 6 at the bottom of the storage barrel 5 and the support seat 4 are opened correspondingly, ensuring that the fertilizer in the storage barrel 5 can fall at the discharge port 6, and in order to conveniently control the amount of discharge, so as to realize the sowing of different amounts of fertilizers in different cultivated land areas, a material control component is arranged at the bottom of the support seat 4, and the material control component is arranged at the discharge port 6 at the bottom of the support seat 4, which can control the projection area of ​​the discharge port 6 toward the material throwing plate 7, that is, it can control the size of the area exposed by the discharge port 6, and then control the amount of fertilizer falling.

[0035] Specific, combined Figure 3 and Figure 5The material control component includes a limit bar 12 arranged on both sides of the discharge port 6, the extension direction of the limit bar 12 is perpendicular to the moving direction of the fertilizer spreading device, and a slide groove 13 is opened in the limit bar 12, and two slide plates 14 that can cover the discharge port 6 are slidably arranged in the slide groove 13, and the bottom of the limit bar 12 after the slide groove 13 is opened is bent upward, which can support the slide plate 14, and the limit bar 12 has a certain elasticity, which can provide a certain clamping force for the slide plate 14 to ensure the stability of the slide plate 14, and the two slide plates 14 can move in opposite directions, and the moving direction is perpendicular to the moving direction of the fertilizer spreading device, which is convenient for the staff to operate the moving slide plate 14, and a pull ring 15 is installed on the opposite side of the two slide plates 14, by pulling the pull ring 15, the slide plate 14 can be driven to move, and then the slide plate 14 is driven to adjust the size of the area covering the discharge port 6, and then the amount of material discharged is controlled.

[0036] In order to realize the spreading function, combined with Figure 4 and Figure 6 A throwing tray 7 is provided at the bottom of the discharge port 6, and blades are provided on the throwing tray 7, which can throw the fallen fertilizer in the direction of the blade opening. In this embodiment, the rotation of the throwing tray 7 is mainly achieved by the cooperation of the rotating shaft 2 and the linkage 8, wherein a part of the linkage 8 is connected to the rotating shaft 2, and the other part is connected to the throwing tray 7. When the moving wheel 3 drives the rotating shaft 2 to rotate, the throwing tray 7 is driven to rotate through the conversion of the linkage 8, which reduces the input of the power source and makes the whole device more compact and tidy.

[0037] In addition, the upper end surface of the material throwing tray 7 can also be set to a spherical surface, that is, the middle of the material throwing tray 7 is higher than the surrounding area, and the spherical surface is set to a relatively gentle arc to prevent the fallen material from sliding directly to the ground, so that when the discharge speed of the discharge port 6 is faster, the time that the material stays on the material throwing tray 7 can be reduced, so that the fertilizer can be quickly thrown out of the material throwing tray 7.

[0038] Among them, the linkage member 8 includes a driving bevel gear 81 coaxial with the rotating shaft 2 and can rotate along with the rotating shaft 2. The driving bevel gear 81 is meshedly connected with a driven bevel gear 82. In order to drive the driven bevel gear 82 to rotate a certain number of circles, and then ensure that the material throwing tray 7 is driven to rotate quickly, the outer diameter of the driving bevel gear 81 is larger than the outer diameter of the driven bevel gear 82 to ensure a suitable transmission ratio. The upper end of the driven bevel gear 82 is connected to a connecting shaft 83, and the connecting shaft 83 is connected to the bottom end of the material throwing tray 7, and the material throwing tray 7 can be driven to rotate through the connecting shaft 83. The two push rods 1 are movable, and a support rod 9 is connected between them, and the support rod 9 is located under the support seat 4, and a support plate 10 is installed on one side, and the connecting shaft 83 passes through the support plate 10 and is connected to the material throwing tray 7, and the connecting shaft 83 is rotatably arranged, and the stability of the connecting shaft 83 can be improved by the support plate 10, and in order to further improve the stability, a limiting cylinder 11 is arranged on the support plate 10, and the connecting shaft 83 passes through the limiting cylinder 11 and is rotatably connected thereto, and the limiting cylinder 11 can wrap a part of the connecting shaft 83 to reduce the shaking of the connecting shaft 83.

[0039] It should be noted that the setting height of the connecting shaft 83 should ensure that the material throwing port on the upper side of the material throwing plate 7 is higher than the moving wheel 3, to ensure that during the material throwing process, the obstruction of the fertilizer by the moving wheel 3 is reduced, to ensure that more fertilizer can be spread on the surrounding cultivated land, and to improve the efficiency of spreading.

[0040] In order to improve the stability of the support seat 4, a reinforcing rod 16 is connected to the bottom of the support seat 4. The end of the reinforcing rod 16 away from the support seat 4 is connected to the support rod 9, and the reinforcing rod 16 should be connected to the support seat 4 near the front end to ensure that the reinforcing rod 16 can be closer to the free end of the support seat 4 to improve the supporting capacity.
