Description

Technical Field

[0001] This utility model belongs to the field of rice transplanter wheel technology, specifically a universal high-speed rice transplanter variable angle tank wheel. Background Technology

[0002] In the process of agricultural modernization, the agricultural workforce is gradually decreasing while labor costs are rising. This has prompted farmers and agricultural production enterprises to seek more efficient agricultural machinery to replace manual labor. The market demand for high-speed rice transplanters is gradually increasing, and major agricultural machinery manufacturers are investing in research and development and production, driving optimization in performance, functionality, and price. The use of high-speed rice transplanters can effectively reduce agricultural production costs. Although the purchase and maintenance of the equipment itself requires certain expenses, in the long run, its high efficiency allows for the completion of large-scale rice transplanting in a short time, reducing labor costs and time, and improving the economic benefits of agricultural production.

[0003] When existing rice transplanter wheels are used in paddy fields, the blades are fixed and used for forward transplanting. When reversing, the wheel blades first insert into the soil and then rotate out, carrying a large amount of soil. The soil not only increases the weight of the wheel, leading to an increase in the overall energy consumption of the rice transplanter, but also easily causes the machine to get stuck (especially in saline-alkali land, low-lying areas, and deep muddy fields), affecting the transplanting operation.

[0004] To address this issue, those skilled in the art have proposed a universal high-speed rice transplanter with variable-angle tank wheels to solve the problems raised in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a universal high-speed rice transplanter with variable angle tank wheel, which solves the problem in the prior art that when the rice transplanter wheel is working in the paddy field, the wheel blades first insert into the soil when reversing, and then rotate out carrying a large amount of soil.

[0006] A variable angle tank wheel for a general-purpose high-speed rice transplanter includes: a drive wheel, which includes an inner wheel and an outer wheel, wherein the outer wheel is rotatably mounted on the periphery of the inner wheel, and a plurality of connecting seats are fixedly mounted on the inner sidewall of the inner wheel;

[0007] A limiting component, comprising a first limiting edge and a second limiting edge;

[0008] The support assembly includes a support blade and a connecting plate. Two sets of connecting plates are fixedly connected to the bottom surface of the support blade. The connecting plates are rotatably installed at the connecting seat. The support blade is located within the first limiting edge and the second limiting edge.

[0009] Preferably, the inner wall of the inner wheel is provided with a drive disc, the inner wall of the drive disc is provided with a connecting sleeve, and a plurality of drive rods are fixedly connected between the drive disc and the inner wheel.

[0010] Preferably, the support blade is located on the periphery of the outer wheel, and the outer wheel is located between the two sets of connecting plates.

[0011] Preferably, a positioning rod is installed between the connecting plate and the connecting seat.

[0012] Preferably, there are ten sets of both the limiting component and the supporting component.

[0013] Preferably, both the limiting component and the support component are in sets of twelve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention, by setting a limiting component and a support component, allows the support blades to detach in an upright posture when emerging from the paddy field in both forward and reverse states. Compared to traditional wheels, this effectively reduces the amount of soil carried out by the outer wheels, lowers the extra weight caused by soil adhesion, reduces the energy consumption of the rice transplanter, and to some extent avoids the adverse effects of soil falling on the growth of transplanted seedlings, thus improving the survival rate of transplanted rice and crop yield.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] Example: As attached Figure 1 As shown: This utility model provides a universal high-speed rice transplanter variable angle tank wheel, including a drive wheel, a limiting component 4 and a support component 5;

[0022] The drive wheel includes an inner wheel 2 and an outer wheel 3. The outer wheel 3 is rotatably mounted on the periphery of the inner wheel 2. Several connecting seats 201 are fixedly mounted on the inner side wall of the inner wheel 2. A drive disc 1 is provided on the inner wall of the inner wheel 2. A connecting sleeve 101 is provided on the inner wall of the drive disc 1. Several drive rods 102 are fixedly connected between the drive disc 1 and the inner wheel 2. The tank wheel can be driven by the connecting sleeve 101. By rotating the drive disc 1, the drive rods 102 and the inner wheel 2 are driven to rotate. Since the outer wheel 3 is rotatably connected to the inner wheel 2, the inner wheel 2 cannot directly drive the outer wheel 3. At this time, the inner wheel 2 spins freely, and the outer wheel 3 cannot rotate.

[0023] As attached Figure 2 As shown: The limiting component 4 includes a first limiting ridge 401 and a second limiting ridge 402. Several first limiting ridges 401 and second limiting ridges 402 are fixed to the periphery of the outer wheel 3 and arranged in a circular array.

[0024] The support assembly 5 includes a support blade 501 and a connecting plate 502. Two sets of connecting plates 502 are fixedly connected to the bottom surface of the support blade 501. The connecting plates 502 are rotatably mounted on the connecting seat 201. The support blade 501 is located within the first limiting edge 401 and the second limiting edge 402. The support blade 501 is located on the periphery of the outer wheel 3, and the outer wheel 3 is located between the two sets of connecting plates 502. A positioning rod 503 is installed between the connecting plate 502 and the connecting seat 201. The two sets of connecting plates 502 are connected by the positioning rod 503. The support blade 501 is restricted by the connecting plate 502 and can rotate stably around the positioning rod 503. Both the limiting assembly 4 and the support assembly 5 have ten or twelve sets of connections.

[0025] By setting the support component 5, when the inner wheel 2 rotates, it drives the support blade 501 to move with the inner wheel 2. The support blade 501 is affected by gravity and the rotation of the inner wheel 2, and by setting the connecting seat 201, the support blade 501 can generate corresponding deflection.

[0026] When the inner wheel 2 rotates clockwise, the support blade 501 moves accordingly. When the support blade 501 contacts the second limiting edge 402, the inner wheel 2 continues to rotate, causing the support blade 501 to be stuck at the second limiting edge 402. Multiple sets of support blades 501 are simultaneously stuck at the second limiting edge 402. At this time, the outer wheel 3 is driven by the support blades 501. The support blades 501 at this time deflect in the opposite direction to the rotation of the inner wheel 2. When the support blades 501 are locked by the second limiting edge 402, the outer wheel 3 is stably driven. When a set of support blades 501 drives the outer wheel 3 into the paddy field, by controlling the length of the connecting plate 502 and the distance between the first limiting edge 401 and the second limiting edge 402, the support blades 501 in contact with the ground are made to be in a relatively horizontal state, so that they can contact the ground horizontally and come out of the paddy field vertically after rotation, ensuring grip while effectively reducing the amount of soil carried after exiting the water.

[0027] When reversing is required, the inner wheel 2 is rotated by reverse drive. At this time, the inner wheel 2 drives multiple sets of support blades 501 to move in the opposite direction, so that the multiple sets of support blades 501 are flipped and locked at the first limit ridge 401, thereby ensuring the driving force when reversing. Moreover, the state of the support blades 501 in contact with the ground and coming out of the paddy field is the same as when moving forward, thus ensuring that the amount of soil carried by the outlet can be effectively reduced when moving forward and reversing.

[0028] As can be seen from the above, the tank wheel is connected to the power output component of the rice transplanter via the connecting sleeve 101. When the rice transplanter starts power transmission, the power is transmitted to the drive disc 1, causing it to start rotating. Since the drive disc 1 and the inner wheel 2 are connected via the drive rod 102, the inner wheel 2 also rotates. The outer wheel 3 is rotatably mounted on the circumference of the inner wheel 2. In the initial state, the inner wheel 2 cannot directly drive the outer wheel 3; the inner wheel 2 is in an idle state, while the outer wheel 3 remains stationary.

[0029] When the inner wheel 2 rotates clockwise, the support blade 501 will move along with the inner wheel 2 and produce a corresponding deflection due to the influence of gravity and the rotation of the inner wheel 2.

[0030] As the inner wheel 2 continues to rotate clockwise, the support blade 501 will come into contact with the second limiting edge 402 fixed on the periphery of the outer wheel 3. Then the inner wheel 2 continues to rotate, causing the support blade 501 to be stuck at the second limiting edge 402. Since both the limiting component 4 and the support component 5 are ten sets, multiple sets of support blades 501 are stuck at the second limiting edge 402 at the same time. At this time, the inner wheel 2 can drive the outer wheel 3 to start rotating through the stuck support blades 501.

[0031] When the bottom support blade 501 drives the outer wheel 3 into the paddy field, the support blade 501 in contact with the ground is in a relatively horizontal state and makes flat contact with the ground, thus ensuring good grip. As the wheel continues to rotate, the support blade 501 will stand up and come out of the paddy field after rotation, effectively reducing the amount of soil carried by the outer wheel 3 after exiting the water.

[0032] When reversing is required, the rice transplanter drives the inner wheel 2 to rotate in the opposite direction. The inner wheel 2 drives multiple sets of support blades 501 to move in the opposite direction, causing the multiple sets of support blades 501 to flip and lock at the first limit ridge 401. This ensures that the outer wheel 3 can also obtain stable driving force when reversing, realizing the reversing operation of the rice transplanter. Furthermore, the state of the support blades 501 in contact with the ground and emerging from the paddy field is the same as when moving forward, thus ensuring that the amount of soil carried by the outlet can be effectively reduced when moving forward and reversing.
