Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery wheel technology, and in particular relates to a rice transplanter anti-sinking wheel. Background Technology

[0002] In the field of agricultural production, rice transplanters are key equipment for realizing the mechanization of rice planting, which greatly improves transplanting efficiency and reduces labor costs. However, when rice transplanters operate in paddy fields, they face many challenges, among which the problem of wheels easily getting stuck in silt is particularly prominent.

[0003] The geological conditions of paddy fields are complex, with significant differences in silt depth and soil viscosity. To prevent rice transplanter wheels from sinking into the silt, it is usually necessary to install anti-sinking plates that are wider than the wheel width. However, traditional rice transplanter wheel anti-sinking plates are usually molded as a single piece with the wheel body. This structure makes maintenance and replacement inconvenient. When an anti-sinking plate is damaged, the entire wheel usually needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a rice transplanter anti-sinking wheel that allows for easy removal and replacement of the anti-sinking plate on the wheel, thereby reducing maintenance costs and time.

[0005] In view of this, the present invention provides a rice transplanter anti-sinking wheel, comprising:

[0006] Wheel body;

[0007] The chain links are connected by multiple hinges at the beginning and end, forming a ring around the wheel body, and include a connecting end for connection and an anti-sinking plate for increasing the support area;

[0008] The connecting post is mounted on the wheel and is used to limit the circumferential movement of the chain link.

[0009] In the above technical solution, further:

[0010] The anti-sinking plate bends at both ends along the wheel body axis away from the axis to form an inner groove, and a support rib is provided in the inner groove;

[0011] The support ribs are multiple and arranged at equal intervals to form anti-slip patterns.

[0012] In the above technical solution, further:

[0013] Both the inner groove and the support rib have triangular cross-sections.

[0014] In the above technical solution, further:

[0015] The anti-sinking plate has a reinforcing rib on the side closest to the axis;

[0016] Among them, the reinforcing ribs and the supporting ribs are set accordingly.

[0017] In the above technical solution, further:

[0018] The two ends of the connector are respectively formed with a protruding part and a concave part;

[0019] The protruding part has a mounting groove that is compatible with the connecting column.

[0020] In the above technical solution, further:

[0021] A U-shaped frame is installed in the mounting slot, and one open end of the U-shaped frame forms a connecting arm that can be bent under pressure.

[0022] The mounting groove has a first pin hole on its inner wall and a second pin hole in its recessed part. A pin is provided at the end of the connecting arm located at the opening of the U-shaped frame, passing through the first pin hole and the second pin hole.

[0023] In the above technical solution, further:

[0024] The mounting slot has mounting holes on its inner wall;

[0025] The connecting arm has a protrusion that matches the mounting hole.

[0026] In the above technical solution, further:

[0027] There is a gap between the anti-sinking plates on two adjacent links.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. By placing anti-sinking plates on the chain links and then fitting them onto the wheel body through multiple hinged chain links, the wheel is prevented from sinking. The hinged chain links can be replaced individually, and if an anti-sinking plate is damaged, it can be easily disassembled and replaced. At the same time, a connecting post is formed on the wheel body to ensure the stability of the connection between the chain links and the wheel body.

[0030] 2. By bending the anti-slip plate to form an inner groove and setting support ribs in the inner groove, not only is the structural strength of the anti-slip plate improved, but also multiple support ribs are arranged at equal intervals to form anti-slip patterns, further preventing wheel slippage.

[0031] 3. By using a U-shaped frame and a connecting arm under pressure bending to push the pin to install and connect two adjacent chain links, the ease of disassembling and assembling the chain links is effectively improved, as is the ease of maintenance and replacement.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides a rice transplanter anti-sinking wheel, including:

[0041] Wheel 1;

[0042] The chain link 2 has multiple hinges at the beginning and end, forming a ring around the wheel body 1, and includes a connecting end 20 for connection and an anti-sinking plate 21 for increasing the support area;

[0043] The connecting post 3 is mounted on the wheel body 1 and is used to limit the link 2 in the circumferential direction;

[0044] The connecting end 20 and the anti-sinking plate 21 adopt an integrated structure;

[0045] Meanwhile, the surfaces of the anti-sinking plate 21 and the connecting end 20 can both be arc-shaped, and the connecting column 3 and the wheel body 1 can be an integral structure.

[0046] As can be seen from this embodiment, by setting the anti-sinking plate 21 on the chain link 2, and then by fitting multiple chain links 2 connected end to end on the wheel body 1, the wheel can be prevented from sinking. Furthermore, the hinged chain links 2 can be replaced individually. When a certain anti-sinking plate 21 is damaged, it is convenient to disassemble and replace it individually. At the same time, a connecting post 3 is formed on the wheel body 1 to ensure the stability of the connection between the chain link 2 and the wheel body 1.

[0047] The use of curved surfaces for both the anti-slip plate 21 and the connecting end 20 reduces the bumpiness when the wheels are rolling, thus improving comfort.

[0048] Example 2:

[0049] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0050] The anti-sinking plate 21 is bent at both ends along the axis of the wheel body 1 away from the axis to form an inner groove 22, and a support rib 23 is provided in the inner groove 22;

[0051] Among them, there are multiple support ribs 23, which are arranged at equal intervals to form anti-slip texture;

[0052] Meanwhile, the support rib 23 and the anti-slip plate 21 can be integrated into one structure, and the specific anti-slip texture is formed by the gap 6 between two adjacent support ribs 23.

[0053] As can be seen from this embodiment, by bending the anti-slip plate 21 to form an inner groove 22 and setting a support rib 23 in the inner groove 22, not only is the structural strength of the anti-slip plate 21 improved, but also multiple support ribs 23 can be arranged at equal intervals to form anti-slip patterns, further preventing wheel slippage.

[0054] Example 3:

[0055] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0056] Both the inner groove 22 and the support rib 23 have triangular cross-sections;

[0057] Specifically, when the anti-sinking plate 21 contacts the ground, the triangular structure is an upright isosceles triangle.

[0058] As can be seen from this embodiment, by setting the cross-sections of the inner groove 22 and the support rib 23 into triangular structures, the structural strength of the support rib 23 and the anti-sinking plate 21 can be further improved. Furthermore, when the anti-sinking plate 21 contacts the ground, the triangular structure is an upright isosceles triangle, which can further enhance the strength brought by the triangular structure, reduce the possibility of damage to the anti-sinking plate 21, and extend its service life.

[0059] Example 4:

[0060] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0061] The anti-sinking plate 21 is provided with a reinforcing rib 24 on the side near the axis;

[0062] Among them, the reinforcing rib 24 is provided in correspondence with the supporting rib 23;

[0063] Meanwhile, the reinforcing rib 24 and the anti-sinking plate 21 adopt an integrated structure.

[0064] As can be seen from this embodiment, by setting the reinforcing rib 24, the structural strength of the anti-sinking plate 21 is further improved, and by setting it in a corresponding manner with the supporting rib 23, the reinforcing rib 24 and the supporting rib 23 can have a mutual supporting effect, thus ensuring the structural strength of the anti-sinking plate 21.

[0065] Example 5:

[0066] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0067] The two ends of the connecting end 20 are respectively formed with a matching protrusion 25 and a concave part 26;

[0068] The protrusion 25 has a mounting groove 4 that is adapted to the connecting post 3.

[0069] As can be seen from this embodiment, the protrusions 25 and concave portions 26 formed at both ends of the connecting end 20 improve the adaptability and stability of the connection between two adjacent links 2, and the protrusions 25 are provided with mounting grooves 4 that are adapted to the connecting post 3, thereby improving the limiting effect of the connecting post 3 on the link 2 and improving the stability of the link 2 installation.

[0070] Example 6:

[0071] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0072] A U-shaped frame 5 is installed in the mounting slot 4, and one open end of the U-shaped frame 5 forms a connecting arm 50 that can be bent under pressure.

[0073] The inner wall of the mounting groove 4 is provided with a first pin hole 40, the inner recess 26 is provided with a second pin hole 41, and the connecting arm 50 is provided with a pin 51 that passes through the first pin hole 40 and the second pin hole 41 at the opening of the U-shaped frame 5.

[0074] Meanwhile, the pin 51 and the U-shaped frame 5 adopt an integrated structure.

[0075] As can be seen from this embodiment, by using a U-shaped frame 5 and a pressure-bending connecting arm 50 to push the pin 51 to install and connect two adjacent chain links 2, that is, by pushing the pin 51, two adjacent chain links 2 can be separated, which effectively improves the convenience of disassembling and assembling the chain links 2 and improves the convenience of maintenance and replacement.

[0076] Meanwhile, the chain link 2 is hinged by the pin 51 passing through the first pin hole 40 and the second pin hole 41. The structure is simple, and the U-shaped frame 5 is set in the mounting groove 4, which can prevent the U-shaped frame 5 from falling off, improve the stability of the connection between the pin 51 and the first pin hole 40 and the second pin hole 41, and make it less likely for two adjacent chain links 2 to fall off, thereby improving the installation stability of the anti-sinking plate 21.

[0077] Example 7:

[0078] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0079] The inner wall of the mounting groove 4 is provided with mounting holes 42;

[0080] The connecting arm 50 is provided with a protrusion 52 that is adapted to the mounting hole 42;

[0081] Meanwhile, the protrusion 52 and the connecting arm 50 can be integrated into one structure.

[0082] As can be seen from this embodiment, by setting the protrusion 52 on the connecting arm 50 and adapting it to the mounting hole 42 opened on the inner wall of the mounting groove 4, the installation stability of the U-shaped frame 5 in the mounting groove 4 can be improved, and the connection stability between two adjacent links 2 can be further improved.

[0083] Meanwhile, the protrusion 52 and the mounting hole 42 facilitate the installation of the chain link 2. Specifically, multiple chain links 2 are first connected by the U-shaped bracket 5 to form a complete chain link 2. Then, the wheel body 1 is fitted onto the chain link 2, and the mounting hole 42 is aligned with the corresponding connecting post 3. When connecting the last pair of adjacent chain links 2, the U-shaped bracket 5 is first installed in the mounting groove 4, so that the protrusion 52 aligns with the mounting hole 42, and the pin 51 aligns with the first pin hole 40. Then... After the protrusion 25 of the link 2 is pushed into the concave part 26, the force applied to the pin 51 is released. After the pin 51 is aligned with the second pin hole 41, the elastic reset of the connecting arm 50 will insert the pin 51 into the second pin hole 41 to achieve connection. During this process, the cooperation between the protrusion 52, the mounting hole 42, and the pin 51 with the first pin hole 40 can limit the U-shaped frame 5, improving the convenience of connecting the last set of two adjacent links 2.

[0084] Example 8:

[0085] This embodiment provides a rice transplanter anti-sinking wheel, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0086] A gap 6 is formed between the anti-sinking plates 21 on each pair of adjacent chain links 2.

[0087] As can be seen from this embodiment, the gap 6 formed between the anti-sinking plates 21 on each pair of adjacent chain links 2 allows the mud and water in the paddy field to flow through the gap 6, reducing the resistance to wheel travel caused by the anti-sinking plates 21. Specifically, when the anti-sinking plates 21 rise with the rotation of the wheel, they avoid carrying too much mud and water, allowing the mud and water to flow through the gap 6.

[0088] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
