Technical Field
[0001] This utility model belongs to the field of agricultural technology, specifically relating to a traction device for agricultural machinery. Background Technology
[0002] Agriculture is an industry that produces food and industrial raw materials through the cultivation of plants and animals. It belongs to the primary sector, and the science that studies agriculture is called agronomy. Its objects of labor are living plants and animals, and the final products are also the plants and animals themselves. Specifically, agriculture is the production sector in which people utilize the life functions of plants and animals to transform the matter and energy of nature into products needed by humankind. We generally refer to all sectors that utilize the growth and development patterns of plants and animals to obtain products through artificial cultivation as agriculture. Agriculture is a fundamental industry supporting national economic construction and development.
[0003] In agricultural production, machinery is often used for operations. Most machinery requires a traction device for towing. However, existing traction devices are mostly simple towing frames, with one end fixed to the tractor and the other end fixed to the agricultural machinery. During operation, the tractor moves the towing frame, thus pulling the agricultural machinery. However, when the tractor suddenly brakes, due to inertia, the agricultural machinery will continue to move forward, potentially causing a collision and damage between the machinery and the tractor. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

[0016] The traction device for agricultural machinery of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0018] This embodiment discloses a traction device for agricultural machinery. Through the ingenious design of the base plate 3, limiting rod 4, mounting base 5, buffer assembly 7, and connecting rod assembly 6, it can play a buffering role during the traction of agricultural machinery, effectively avoiding damage caused by collision between the agricultural machinery and the tractor due to inertial forces during traction. (Refer to...) Figures 1-4 It mainly includes a traction frame 1 with a rotating rod 11 rotatably mounted at one end, and a second connector 12 symmetrically fixed at both ends of the rotating rod 11 (the second connector 12 is fixedly connected to agricultural machinery, which is not shown, as it is existing equipment and will not be described in detail). Its characteristic is that a mounting frame 2 is fixedly connected to the middle of one end of the traction frame 1, and several base plates 3 are evenly spaced and fixedly connected inside the mounting frame 2. Several limiting rods 4 are evenly spaced and fixedly connected to the upper end of each base plate 3 along the circumferential direction. Each base plate 3 has a [missing information - likely a design feature] directly above it. There is a mounting base 5, which is sleeved on the corresponding limiting rod 4. Each limiting rod 4 is equipped with a buffer assembly 7, and the buffer assembly 7 is located between the mounting base 5 and the base plate 3. A number of connecting rod assemblies 6 are evenly spaced along the circumferential direction between the mounting base 5 and the base plate 3. A connecting plate 8 is fixedly connected to the end of each mounting base 5 away from the traction frame 1. A first connector 10 is installed on the connecting plate 8 through a connector 9 (the first connector 10 is fixedly connected to the tractor vehicle, which is not shown. Due to the existing equipment, the tractor vehicle will not be described in detail). By setting the connector 9, flexible rotation between the first connector 10 and the connecting plate 8 at multiple angles is achieved, thereby effectively preventing the agricultural machinery from overturning when the tractor turns or makes a U-turn due to excessively large angles.
[0019] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The buffer assembly 7 includes a plurality of elastic balls 701 and a plurality of partitions 702. Each of the limiting rods 4 is fitted with a plurality of elastic balls 701 and a plurality of partitions 702, and the elastic balls 701 and the partitions 702 are alternately arranged. Through the combined design of the elastic ball 701 and the partition 702, when agricultural machinery moves forward due to inertia, the impact force generated can be evenly transmitted to each elastic ball 701, rather than concentrated on one or a few elastic balls 701, thereby playing a more effective buffering role and reducing damage to agricultural machinery.
[0020] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4A baffle 401 is fixedly connected to the end of the limiting rod 4 away from the base plate 3 to prevent the mounting seat 5 from sliding off the limiting rod 4. With the setting of the baffle 401, when the tractor is towing, it can block the mounting seat 5 when it is about to slide off the limiting rod 4, thereby effectively preventing the mounting seat 5 from sliding off the limiting rod 4.
[0021] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The linkage assembly 6 includes a first linkage 601, a second linkage 602, a third linkage 603, and a fourth linkage 604. Each base plate 3 has a plurality of first linkages 601 fixedly connected at even intervals along the circumferential direction. The upper end of each first linkage 601 is rotatably connected to a second linkage 602. The upper end of the second linkage 602 is rotatably connected to a third linkage 603. The upper end of the third linkage 603 is rotatably connected to a fourth linkage 604. The upper end of the fourth linkage 604 is fixedly connected to the mounting base 5. Through the coordinated design of the first link 601, the second link 602, the third link 603 and the fourth link 604, the force can be evenly distributed and transmitted, so that the mounting base 5 remains stable during the up and down movement, ensuring the stability of the entire traction device during operation; and the structural strength of the device can also be effectively improved.
[0022] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The mounting base 5 is provided with a plurality of limiting ports 501 evenly spaced along the circumferential direction to limit the corresponding third link 603; by setting the limiting ports 501, the third link 603 can be limited, thereby making the base plate 3 move more smoothly.
[0023] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The connector 9 includes a first U-shaped seat 902, a first rotating shaft 902, a second rotating shaft 903, and a second U-shaped seat 904. The first U-shaped seat 902 is fixedly connected to the connecting plate 8. The first rotating shaft 902 is rotatably connected to the end of the first U-shaped seat 902 away from the connecting plate 8. The second rotating shaft 903 is fixedly connected to the middle of the first rotating shaft 902, and the second rotating shaft 903 and the first rotating shaft 902 are arranged in a cross shape. The second U-shaped seat 904 is rotatably connected to the second rotating shaft 903, and the second U-shaped seat 904 is fixedly connected to the first connecting plate 8. Through the coordinated design of the first U-shaped seat 902, the first rotating shaft 902, the second rotating shaft 903, and the second U-shaped seat 904, the first connector 10 can be rotated up and down and left and right, thereby effectively preventing the agricultural machinery from overturning due to excessive angle when the tractor turns or makes a U-turn.
[0024] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The traction frame 1 is in the shape of an "A". The "A" shape design allows the traction force to be evenly distributed on the two branch rods, avoiding local stress concentration, reducing the risk of the rods breaking or deforming due to excessive force, and improving the load-bearing capacity of the traction frame 1.
[0025] The working principle of the traction device for agricultural machinery of this utility model is as follows: When it is needed, the first connector 10 is fixedly connected to the tractor, and the second connector 12 is fixedly connected to the agricultural machinery. The tractor can be started and the agricultural machinery can be towed by the traction device. During traction, when the tractor suddenly brakes, the agricultural machinery will move forward due to inertia. At this time, the traction frame 1 moves forward, which in turn moves the mounting frame 2 forward. The mounting frame 2 then moves the base plate 3 forward. Through the cooperation of the first link 601, the second link 602, the third link 603, and the fourth link 604, the limiting rod 4 slides on the mounting seat 5. The elastic ball 701 provides some cushioning to the base plate 3, which in turn provides some cushioning to the mounting frame 2, the traction frame 1, and the second connector 12. This provides some cushioning to the agricultural machinery and effectively prevents the agricultural machinery from colliding with the tractor due to inertia during traction.
