Abstract
Description
Technical Field
[0001] This utility model relates to seeders in agricultural machinery, specifically to a fertilizer-applying plow leg reinforcement device for seeders. Background Technology
[0002] In agricultural production, seeders are key agricultural machinery for achieving efficient sowing and fertilization operations. Among them, the fertilizing plow leg (also known as the fertilizing furrow shovel) is the core component of the seeder's fertilization system. Its main function is to accurately deliver fertilizer and apply it to a specific depth in the soil, providing essential nutrients for the early stages of crop growth. It directly affects the accuracy of fertilization and the subsequent growth of crops.
[0003] Currently, most seeders on the market have their fertilizer plow legs directly connected to the seeder frame via a support frame. However, in actual field operations, the fertilizer plow legs need to be in continuous contact with the soil and withstand external forces such as soil resistance and impacts from stones. These forces are transmitted to the support frame through the fertilizer plow legs. Because the existing connection structure between the support frame and the main frame lacks sufficient reinforcement, the support frame is prone to bending and deformation under long-term stress. This can cause the fertilizer plow legs to shift, resulting in inaccurate fertilization depth, fertilizer spillage, or blockage of the fertilization channel. This severely hinders the normal fertilization operation of the seeder, reduces agricultural production efficiency, and increases farmers' operating costs and labor intensity. Summary of the Invention
[0004] This invention addresses the technical problem of easy deformation of the fertilizer plow leg support frame of a seeder, which leads to obstruction of fertilization in the prior art. It provides a seeder fertilizer plow leg reinforcement device with stable structure and significant reinforcement effect, so as to improve the reliability of the connection between the fertilizer plow leg and the frame and ensure the stability and accuracy of the seeder fertilization operation.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fertilizing plow leg reinforcement device for a seeder, including a special-shaped structural beam of the seeder, a fertilizing plow leg, and a support frame connecting the fertilizing plow leg and the beam. A connecting plate is provided on the beam, and the hook part on the upper part of the connecting plate is adapted to the outer contour of the outer wall of the beam. The hook part is hooked on the beam, and the lower part of the connecting plate is connected to the fertilizing plow leg and the support frame by bolts. A locking block is provided at the lower part of the beam, and a pad is provided at the rear part of the beam between the connecting plate and the support frame. A locking screw passing through the locking block is threadedly connected to the threaded hole on the pad. A locking nut is provided on the locking screw at the end of the locking block.
[0006] The hook part of the connecting plate and the contact surface of the main beam form a 45° angle.
[0007] The contact end of the locking block and the main beam is adapted to the outer wall contour of the lower part of the main beam, and the contact end of the locking block and the connecting plate is adapted to the outer wall contour of the lower part of the connecting plate.
[0008] The connecting plate, locking block, pad, and locking screw are all made of high-strength metal.
[0009] The seeder fertilizer plow leg reinforcement device designed using the above-mentioned technical solution has the following beneficial effects: 1. Significantly improved structural stability: The 45° fitting design and hook structure of the connecting plate achieve a tight fit and initial fixation between the connecting plate and the irregular beam. Combined with the compression reinforcement of locking blocks, pads, and locking screws, a double fixing structure of "hook + compression" is formed, which greatly enhances the overall strength of the connection between the fertilizing plow leg and the irregular beam, effectively disperses the external force borne by the fertilizing plow leg, and avoids the support frame from deforming due to excessive local stress. This fundamentally solves the problem of easy deformation and fertilization obstruction of the existing fertilizing plow leg support frame. 2. Easy installation and maintenance: All components of this device are assembled using detachable connections such as bolts and screws, eliminating the need for significant modifications to the original structure of the seeder. The installation process is simple and efficient. During later maintenance, damaged parts can be replaced simply by removing the corresponding bolts or screws, reducing maintenance difficulty and costs. 3. Strong adaptability: The mating surfaces of the connecting plate and locking block can be adapted to the contours of the irregular beams of different models of seeders, making it widely applicable to various seeders with irregular beam structures, and possessing strong versatility and market application value.

[0012] The following description, in conjunction with the accompanying drawings, details the fertilizer application plow leg reinforcement device for the seeder of this utility model.
[0013] This utility model relates to a reinforced fertilizer plow leg device for a seeder. See [link / reference] Figures 1 to 3The system includes a main beam 1 of the seeder with an irregular structure, a fertilizing plow leg 2, and a support frame 3 connecting the fertilizing plow leg 2 and the main beam 1. A connecting plate 4 is installed on the main beam 1. The hook part 41 on the upper part of the connecting plate 4 is adapted to the outer contour of the outer wall of the main beam 1. The hook part 41 hooks onto the main beam 1. The contact surface between the hook part 41 of the connecting plate 4 and the main beam 1 forms a 45° angle. This angle design allows the connecting plate 4 to better distribute lateral and longitudinal external forces. Two bolt holes are opened at the lower part of the connecting plate 4. Bolts 8 pass through the bolt holes of the connecting plate 4 and the corresponding mounting holes on the support frame 3 in sequence, and finally connect to the threaded hole at the bottom of the fertilizing plow leg 2. After tightening the bolts 8, the connecting plate 4, the support frame 3, and the fertilizing plow leg 2 form a solid integral structure.
[0014] A locking block 5 is provided at the lower part of the main beam 1, and a pad 6 is provided at the rear of the main beam 1 between the connecting plate 4 and the support frame 3. A locking screw 7 passing through the locking block 5 is threadedly connected to the threaded hole on the pad 6. Specifically, an internal threaded hole is opened at the center of the pad 6, which matches the external thread of the locking screw 7. The shank of the locking screw 7 passes through the through hole at the center of the locking block 5, the gap between the main beam 1 and the pad 6, and is finally screwed into the internal threaded hole of the pad 6. The contact side of the locking block 5 and the main beam 1 is adapted to the outer wall contour of the lower part of the main beam 1, and the contact side of the locking block 5 and the connecting plate 4 is adapted to the outer wall contour of the lower part of the connecting plate 4, ensuring that the locking block 5 can be tightly fitted with both the main beam 1 and the connecting plate 4. A locking nut 9 is provided on the locking screw 7 located at the end of the locking block 5. When the locking nut 9 is tightened clockwise, the locking block 5 moves towards the contact point between the main beam 1 and the connecting plate 4 under the pushing force of the screw until the connecting plate 4 is firmly clamped, thereby achieving secondary fixation between the connecting plate 4 and the irregular main beam 1.
[0015] The connecting plate 4, locking block 5, pad 6, and locking screw 7 of this utility model are all made of high-strength metal material.
[0016] In actual operation, the soil resistance borne by the fertilizing plow leg 2 is transmitted to the main beam 1 through the support frame 3 and the connecting plate 4. Since the connecting plate 4 and the main beam 1 are fitted at 45°, and with the double fixing structure of the locking block 5, the external force is effectively dispersed. The support frame 3 will not deform due to excessive local force, thus ensuring the positional stability of the fertilizing plow leg 2 and ensuring that the fertilizing operation is continuous and accurate.
