Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and specifically refers to a motor-driven sprocket transmission anti-loosening tensioning structure. Background Technology

[0002] Agricultural machinery (hereinafter referred to as "agricultural machinery") refers to various mechanical equipment used in agricultural production and related processes, including tractors, seeders, harvesters, and plant protection drones, aiming to improve agricultural production efficiency, reduce labor intensity, and ensure food security. Currently, agricultural machinery has become a core force driving the high-quality development of modern agriculture.

[0003] With the continuous development of new energy power systems, agricultural machinery using electric tractors is gradually becoming mainstream in the market. For example, Chinese Patent Publication No. CN223094161U discloses a drive module for an agricultural tiller, including a transmission gearbox, a travel motor mounted on the transmission gearbox, and a transmission pulley assembly between the travel motor and the transmission gearbox. The transmission gearbox is provided with a mounting bracket for supporting the travel motor and the transmission pulley assembly. The mounting bracket includes a support plate fixed to the transmission gearbox and a sliding block slidably mounted on the support plate for fixing the travel motor. One end of the support plate is provided with a mounting groove for adjusting the position of the sliding block. By using a transmission pulley assembly between the travel motor and the transmission gearbox to connect and transmit power, the service life of the drive module can be improved.

[0004] However, in the aforementioned patent, the transmission pulley module is not equipped with a tensioning device, and the belt will lengthen after a period of use, causing the belt to loosen and making it impossible to achieve stable kinetic energy transmission.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] See Figures 1 to 4As shown, a motor-driven sprocket transmission anti-loosening tensioning structure includes: a support plate 231, a sliding plate 232 disposed on the support plate 231, and an adjusting block 233 disposed on one side of the sliding plate 232. A first sprocket 23A and a second sprocket 23B are respectively mounted on the support plate 231 and the sliding plate 232, and a motor 22 is mounted on the sliding plate 232. The support plate 231 is provided with a cavity 2310 for mounting the sliding plate 232 and allowing it to slide. The adjusting block 233 is wedge-shaped and located between the sliding plate 232 and the side wall of the cavity 2310, and is fixed to the support plate 231 by an adjusting bolt 234. The second sprocket 23B is mounted on the sliding plate 232, and the position of the sliding plate 232 is adjusted by adjusting the adjusting block 233 through adjusting bolt 234. This allows for adjustment of the distance between the first sprocket 23A and the second sprocket 23B, thereby fine-tuning the tension of the chain 23C and preventing the chain 23C from becoming loose after a period of operation, which would affect its use.

[0021] The adjusting block 233 is located between the first sprocket 23A and the second sprocket 23B. The adjusting bolt 234 passes through the adjusting block 233, and the depth of the adjusting block 233 inserted between the sliding plate 232 and the side wall of the cavity 2310 is adjusted by rotating the adjusting bolt 234. The adjusting block 233 is located between the first sprocket 23A and the second sprocket 23B. When the adjusting bolt 234 is turned, the adjusting block 233 pushes the sliding plate 232, causing the second sprocket 23B to move away from the first sprocket 23A, thereby stretching the chain 23C. Conversely, when the adjusting bolt 234 is turned in the opposite direction, the adjusting block 233 gradually releases its push on the sliding plate 232, thereby loosening the sprocket 23C and preventing the chain 23C from breaking during high-speed movement.

[0022] The support plate 231 is provided with a groove 2311 for accommodating the adjusting block 233. The groove 2311 is located on one side of the cavity 2310 and communicates with the cavity 2310. The adjusting block 233 has a first inclined surface 2331 and a second inclined surface 2332 on both sides for contacting the sliding plate 232 and the side wall of the groove 2311, respectively. The sliding plate 232 has a third inclined surface 2321 on one side for contacting the first inclined surface 2331. The side wall of the groove 2311 forms a fourth inclined surface 2312 for contacting the second inclined surface 2332.

[0023] The motor 22 is fixed to the sliding plate 232 by multiple bolts passing through the support plate 231, and the support plate 231 is provided with multiple travel slots 2313 for the bolts to slide with the sliding plate 232.

[0024] One end of the support plate 231 is mounted on the gearbox 21, and the other end of the support plate 231 is mounted on the frame 1. One end of the support plate 231 is formed with a protrusion 2314 for connecting with the frame 1, and a buffer sleeve 236 is installed inside the protrusion 2314.

[0025] The support plate 231 is also equipped with a protective cover 235 that covers the first sprocket 23A, the second sprocket 23B and the chain 23C.

[0026] In summary, this utility model employs a sliding plate 232 on a support plate 231 for mounting the motor 22 and the second sprocket 23B. An adjusting block 233 is placed between the first sprocket 23A and the second sprocket 23B to adjust the position of the sliding plate 232, thereby controlling the distance between the second sprocket 22B and the first sprocket 23A. An adjusting bolt 234 passes through the adjusting block 233 and is fixed to the support plate 231. When the adjusting bolt 234 is tightened, it pushes the adjusting block 233 into the space between the sliding plate 232 and the groove 2311, thus moving the adjusting block 233 away from the first sprocket 23A. Conversely, when the adjusting bolt 234 is loosened, it pulls the adjusting block 233 outward from between the sliding plate 232 and the groove 2311, thereby adjusting the tension of the sprocket 23C. Loosening the adjusting bolt 234 only reverses the direction of rotation and does not completely detach the adjusting bolt 234 from the support plate 231.

[0027] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
