Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a seeder with a single-sided, non-clogging, adjustable depth and speed-measuring ground wheel structure. Background Technology

[0002] In agricultural sowing operations, the ground wheel is a key component of the seeder, and its performance directly affects the seeder's operating efficiency and sowing quality. However, traditional ground wheel structures have many technical drawbacks in practical applications: traditional ground wheels often adopt a double-sided symmetrical rim design, which makes it easy for soil to accumulate in the gap between the rim and the hub during operation. Especially in sticky and wet soil environments, the continuous accumulation of soil clumps will significantly increase the rotational resistance of the ground wheel, and in severe cases, even cause the ground wheel to jam, greatly affecting the stability of the seeder and reducing operating efficiency; the existing ground wheel's soil penetration depth adjustment method is cumbersome to operate, often requiring complex disassembly and assembly processes, making it difficult to quickly and conveniently adapt to different soil moisture conditions, and making it difficult to ensure consistent sowing depth, thus adversely affecting seedling quality; in addition, the speed measuring device has low integration with the ground wheel structure, the installation and debugging process is complex, and it is easily affected by the operating environment, causing deviations in the speed measuring signal, affecting the accurate control of the sowing amount, and reducing the uniformity of sowing. These problems restrict the improvement of seeder operating performance and urgently need to be solved through structural innovation.

[0003] Therefore, those skilled in the art have provided a single-sided, non-clogging, adjustable-depth, and speed-measuring ground wheel structure for a seeder to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a single-sided, non-clogging, depth-measuring, and speed-measuring ground wheel structure for a seeder, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A seeder with a single-sided, non-clogging, adjustable depth and speed-measuring ground wheel structure, comprising:

[0007] The cantilever has a tire mounted on the front end via a pivot shaft, and the rear end is connected to a quick-adjustable hanger mechanism.

[0008] The quick-adjustable bracket mechanism includes a hook that can be detachably installed on the mounting plate for attaching external equipment; the mounting plate is fixedly connected to the adjustment plate by quick-release screws; the adjustment plate has an adjustable angle connection between its front end and the rear end of the cantilever via depth adjustment holes and pins, and several coaxial depth adjustment holes are provided at corresponding positions on both. By pulling out the pin to adjust the cantilever angle and then reinserting the pin to lock it, the depth of the ground wheel in the soil can be quickly adjusted.

[0009] The tires feature a single-sided flange design, which utilizes centrifugal force and soil compression to reduce soil adhesion;

[0010] The speed sensor is located on one side of the cantilever and installed on the end of the tire axle. It is connected to the external controller signal and is used to collect the wheel speed signal in real time and convert it into the seeder's travel speed.

[0011] As a further embodiment of this utility model: the depth adjustment holes are distributed along the arc-shaped adjustment trajectory of the adjustment plate and the cantilever to form a multi-level depth adjustment structure, with each level corresponding to a different depth of the ground wheel entering the soil.

[0012] As a further improvement of this invention: the speed sensor is synchronously rotated with the tire shaft, and the sensor signal output terminal is connected to an external controller via wired or wireless means to transmit real-time speed data.

[0013] As a further improvement of this utility model: the diameter of one side rim of the tire is larger than the diameter of the main body of the tire, forming a radially extending mudguard structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The single-sided rim design of the tires effectively solves the problem of mud clogging in traditional double-sided rim designs, reducing the rotational resistance of the ground wheel, decreasing the frequency of cleaning, and improving the continuity and efficiency of operations. The quick-adjustable depth adjustment mechanism allows for easy and quick depth adjustment by simply inserting and removing pins, adapting quickly to different soil conditions, ensuring consistent sowing depth, and improving seedling quality. The integrated speed sensor rotates synchronously with the ground wheel, ensuring stable signal transmission, minimal environmental interference, and high speed accuracy. This provides reliable data for precise control of the sowing rate, improving sowing uniformity. The ingenious overall structural design and coordinated operation of all parts significantly optimize the working performance of the seeder's ground wheel. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figures 1-3 This embodiment provides a seeder with a single-sided, non-clogging, adjustable-depth, and speed-measuring ground wheel structure, including:

[0023] The cantilever 3 has a tire 5 mounted on its front end via a pivot shaft, and its rear end is connected to the quick-adjustable hanger mechanism 1.

[0024] The quick-adjustable bracket mechanism 1 includes a hook 101, which is detachably installed on the mounting plate 102 for hanging external equipment; the mounting plate 102 is fixedly connected to the adjusting plate 2 by quick-release screws 103; the front end of the adjusting plate 2 is connected to the rear end of the cantilever 3 by a depth adjustment hole 6 and a pin 7 to form an angle-adjustable connection, and several coaxial depth adjustment holes 6 are opened at corresponding positions of the two. By pulling out the pin 7 to adjust the angle of the cantilever 3 and then re-inserting the pin 7 to lock it, the depth of the ground wheel into the soil can be quickly adjusted.

[0025] Tire 5 adopts a single-sided flange design, which uses centrifugal force and soil compression to reduce soil adhesion;

[0026] Speed ​​sensor 4 is located on one side of cantilever 3 and installed on the shaft end of tire 5. It is connected to the external controller signal and is used to collect the wheel speed signal in real time and convert it into the seeder's travel speed.

[0027] Example 2

[0028] Reference Figures 1-3 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the depth adjustment holes 6 are distributed along the arc-shaped adjustment trajectory of the adjustment plate 2 and the cantilever 3 to form a multi-level depth adjustment structure, with each level corresponding to a different depth of the ground wheel entering the soil.

[0029] Furthermore, the speed sensor 4 is synchronously rotated with the axle of the tire 5, and the sensor signal output terminal is connected to an external controller via wired or wireless means to transmit real-time speed data.

[0030] Furthermore, the diameter of one side rim of the tire 5 is larger than the diameter of the main body of the tire, forming a radially extending mudguard structure.

[0031] Working principle: During sowing operations, the quick-adjustable mounting bracket 1 connects to the main body of the seeder. The quick-release screws 103 between the mounting plate 102 and the adjusting plate 2 are used to adjust the left and right positions of the ground wheel, ensuring coordinated operation with other parts of the seeder. When it is necessary to adjust the depth of the ground wheel into the soil to adapt to different soil moisture conditions, the machine is lifted with the help of a tractor, and the pin 7 at the connection between the adjusting plate 2 and the cantilever 3 is manually pulled out. The angle of the cantilever 3 is adjusted according to the required depth, and the depth adjustment hole 6 at the corresponding position is aligned and then the pin 7 is inserted to lock it, thus quickly completing the depth adjustment. During operation, the single-sided rim design of the tire 5 reduces the adhesion and accumulation of soil on the wheel. The centrifugal force generated when the ground wheel rotates and the squeezing action of the soil will cause the soil to detach naturally, ensuring smooth rotation of the ground wheel. At the same time, the speed sensor 4 installed on the shaft end of the tire 5 rotates synchronously with the ground wheel, collects the speed signal in real time and transmits it to the external controller. The controller converts the speed signal into the travel speed of the seeder, providing data support for precise control of the sowing amount.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
