Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a floating traction device. Background Technology

[0002] Existing agricultural equipment now employs integrated operation, combining multiple machines into a single agricultural vehicle. This allows for the completion of various tasks in a single trip, achieving goals such as fuel savings, cost reduction, time savings, and increased efficiency. For example, adding a seeder to the rear of a rotary tiller ensures the tilled soil is suitable for immediate sowing, significantly reducing tillage and sowing costs while improving efficiency.

[0003] However, when the ground is uneven or undulating, the undulation of the rotary tiller on the level surface will inevitably cause the seeder to undulate as well. This undulation of the seeder will lead to inconsistent sowing depth, resulting in inconsistent germination rates and germination times for seedlings, which seriously affects the survival rate and growth status of crops.

[0004] Therefore, there is an urgent need for a floating traction device that will not affect the operation of rotary tillers and seeders due to uneven ground. Utility Model Content

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example 1:

[0035] like Figure 1-6 As shown, a floating traction device includes a connector 2 and a mounting component 3. The connector 2 and the mounting component 3 are hinged together. The connector 2 includes a limiting part 21, and there is a gap 34 between the limiting part 21 and the mounting component 3. The mounting component 3 and the limiting part 21 restrict the rotation of the connector 2. When the rotary tiller enters an undulating road surface, the mounting component 3 connects to the rotary tiller, and the connector 2 connects to the seeder. During the sowing process, the mounting component 3 does not apply upward or downward force to the connector 2 and the seeder. The seeder sows by adjusting the sowing depth. The seeder is not disturbed by external forces during its vertical movement, resulting in consistent sowing depth, uniform germination time, easier management and maintenance, and higher germination and survival rates. The limiting part 21 and the mounting component 3 are used to restrict the rotation of the connector 2 and limit the range of motion of the seeder connected to the connector 2, thereby better controlling the sowing depth.

[0036] The limiting part 21 restricts the connecting member 2 from rotating clockwise toward the mounting member 3; the limiting part 21 is located below the hinge point. Figure 1 It can be seen that the gap 31 is the included angle between the limiting part 21 and the mounting part 3. When the connecting part 2 rotates around the hinge point, the size of the gap 31 changes. Figure 1 When rotating in the direction of the middle arrow, the mounting part 3 will restrict the rotation of the connecting part 2 to prevent the seeder from falling and control the sowing depth. After sowing is completed, the seeder can be lifted. The limiting part 21 is set below the hinge point to restrict the downward rotation of the connecting part 2, control the sowing depth, and realize the lifting of the seeder.

[0037] The connector 2 also includes a hanging rod 22. One end of the limiting part 21 or one end of the hanging rod 22 is hinged to the mounting part 3. The limiting part 21 is connected to the hanging rod 22. The connector 2 includes two interconnected parts. Either the limiting part 21 or the hanging rod 22 can be hinged to the mounting part 3.

[0038] The limiting part 21 and the hanging rod 22 have an included angle, which is greater than 0° and less than 180°. Analysis shows that the above function can be achieved when the included angle between the limiting part 21 and the hanging rod 22 is between 0° and 180°. This embodiment uses 90° as an example, but other angles are also possible. Figure 5 As shown, the angle between the limiting part 21 and the hanging rod 22 is greater than 90°, or it can be as follows: Figure 6 As shown, the angle between the limiting part 21 and the hanging rod 22 is less than 90°.

[0039] It also includes an adjusting plate 1, which is connected to the mounting member 3. The connecting member 2 is hinged to the mounting member 3 on the adjusting plate 1. The adjusting plate 1 facilitates the hinge connection between the connecting member 2 and the mounting member 3, and also uses the mounting member 3 in cooperation with the limiting part 21 to restrict the rotation of the connecting member 2.

[0040] The mounting component 3 is provided with a mounting positioning groove 33, and the adjusting plate 1 is provided with an adjusting insertion part 12 on one side, which is inserted into the mounting positioning groove 33. The mounting positioning groove 33 and the adjusting insertion part 12 are used to position the adjusting plate 1 mounted on the mounting component 3. The adjusting plate 1 is usually fixed to the mounting component 3 by welding. No measurement is required during welding. It is only necessary to insert the adjusting insertion part 12 of the adjusting plate 1 into the mounting positioning groove 33 to accurately position the adjusting plate 1. In this embodiment, the adjusting plate 1 is vertically connected to the mounting component 3.

[0041] The mounting component 3 is provided with a first mounting hole 31 and a second mounting hole 32, which are used to fix the mounting component 3 on the rotary tiller.

[0042] like Figure 3-4 As shown, the adjusting plate 1 has several mounting holes 11 along its length, and the limiting part 21 has a first hooking hole 211. The connector 4 passes through the mounting holes 11 and the first hooking hole 211 in sequence. The adjusting plate 1 has several mounting holes 11, and the appropriate mounting hole 11 can be selected for installation and fixation according to the sowing depth, the size of the seeder, etc. The multiple mounting holes 11 expand the application range of the traction device. The connector 4 is a pin or a pair of mating bolts and nuts.

[0043] like Figure 1 and Figure 2 As shown, the hanging rod 22 is provided with a second hanging hole 221, and the second hanging hole 221 is connected to the hanging mounting part 5. In this embodiment, the hanging mounting part 5 is used to connect the seeder. If other equipment is to be adapted, different mounting parts are required. This embodiment is only an example of the seeder, but it is not limited to the seeder.

[0044] The adjustment plate 1 is of one type, and the connector 2 is of one type, with the connector 2 located on one side of the adjustment plate 1. A suitable mounting hole 11 is selected as needed, and the plug 4 passes sequentially through the first hook hole 211 and the mounting hole 11. Example 2:

[0045] like Figure 7 and 8 As shown, a floating traction device differs from Embodiment 1 in that it has two adjusting plates 1 and one connecting member 2. The two adjusting plates 1 are arranged parallel to each other, and the connecting member 2 is disposed between the two adjusting plates 1. A suitable mounting hole 11 is selected as needed, and a connector 4 is used to hinge the two adjusting plates 1 and the connecting member 2 together.

[0046] The included angle between the limiting part 21 and the hanging rod 22 is 90°, which can also satisfy the purpose of the mounting part 3 and the limiting part 21 to restrict the rotation of the connecting part 2. Example 3:

[0047] like Figure 9-12 As shown, a floating traction device differs from Embodiment 1 in that the number of adjusting plates 1 is one, and the number of connecting pieces 2 is two. One connecting piece 2 is located on one side of the adjusting plate 1, and the other is located on the other side of the adjusting plate 1, or both connecting pieces 2 are located on one side of the adjusting plate 1. Figure 9 As shown, the two connectors 2 are on both sides of the adjusting plate 1, and the two connectors 2 are at the same height. Figure 10 and Figure 11 As shown, the two connectors 2 are on both sides of the adjusting plate 1, and the two connectors 2 have different heights. Figure 12 As shown in the schematic diagram of another type of connector 2, the connection position between the hanging rod 22 and the limiting part 21 is as follows: Figure 12 As shown, this also satisfies the purpose of the mounting part 3 and the limiting part 21 to restrict the rotation of the connecting part 2. Example 4:

[0048] like Figure 13 and 14 As shown, a floating traction device differs from Embodiment 1 in that it has two adjusting plates 1 and two connecting pieces 2. The two adjusting plates 1 are arranged parallel to each other, and the two connecting pieces 2 are arranged between the two adjusting plates 1. The two connecting pieces 2 are arranged side by side or along the adjusting plates 1. Figure 13 As shown, two connecting pieces 2 are overlapped and arranged between two adjusting plates 1. Figure 14 As shown, two connecting pieces 2 are arranged between the two adjusting plates 1 along the length of the adjusting plate 1.
