Description

Technical Field

[0001] The utility model relates to the technical field of tractor mud pit auxiliary escape, in particular to a wheeled tractor stuck vehicle self-rescue device. Background Art

[0002] It is well known that when a tractor is working in a farmland, when it rains or the water content in the soil is too high, the tractor is easy to get stuck in the soil and cannot move when working, and the tires of the tractor will spin idly and cannot move. Long-term idling of the tractor's tires will easily cause the tractor to get stuck deeper and deeper. In the prior art, a stick is tied to the rear wheel of the tractor to facilitate the tractor to get out of trouble. However, the weight of the tractor is too high, and the stick tied to the rear wheel of the tractor is easy to loosen. In addition, the stick is also easy to get stuck in the soil. The soil is too soft, resulting in the stick being unable to bear force. If the stick cannot bear force, the tractor cannot get out of trouble. For this reason, we propose a self-rescue device for a wheeled tractor stuck in the water. Utility Model Content

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with Figures 1 to 3 A self-rescue device for a wheeled tractor stuck in a vehicle comprises a fixing device 1 and a supporting device 2. The fixing device 1 is provided on the supporting device 2. The fixing devices 1 are arranged in pairs. The supporting device 2 consists of a fixing column 10 and a limiting block 11. The fixing column 10 is connected to the fixing device 1, and the limiting block 11 is provided on the fixing column 10.

[0018] The fixing device 1 is composed of a fixing block 4, a fixing sleeve 6, and a fixing rod 3. The fixing sleeve 6 is provided in the middle position of the front surface of the fixing block 4. The front surface of the fixing block 4 is provided with fixing holes 5 on both sides of the fixing sleeve 6. The fixing holes 5 penetrate the fixing block 4. The fixing rod 3 is provided in the fixing hole 5 on the fixing block 4. The fixing block 4 is fixed to the rear wheel of the tractor through the fixing rod 3.

[0019] A fixing column 10 is provided in the fixing sleeve 6, and a threaded hole 7 is provided on the side wall of the fixing sleeve 6. The threaded hole 7 penetrates the fixing sleeve 6, and a threaded pin 8 is provided in the threaded hole 7 on the fixing sleeve 6. The threaded pin 8 is matched with the threaded hole 7 on the fixing sleeve 6. The fixing column 10 is installed in the fixing sleeve 6 on the fixing block 4 and fixed and limited by the threaded pin 8.

[0020] The fixing rod 3 is a "U"-shaped structure. The fixing rod 3 is inserted into the fixing hole 5 on the fixing block 4. External threads are provided on the outer walls at both ends of the fixing rod 3. Nuts 9 are provided on the fixing rod 3. The nuts 9 are adapted to the external threads on the fixing rod 3. The fixing rod 3 is inserted into the wheel hub and fixed by the nuts 9.

[0021] The fixing column 10 is fixed in the fixing sleeve 6. Both ends of the fixing column 10 are provided with limit blocks 11. The limit blocks 11 are of an arc-shaped structure. The limit blocks 11 are movably connected to the fixing column 10 through threads. When the rear wheel of the tractor rotates, the fixing column 10 is driven to rotate. The length of the fixing column 10 is longer than the diameter of the rear wheel of the tractor. The fixing column 10 rotates and contacts the ground to support the rear wheel of the tractor, so as to help the tractor get out of the mud pit. The limit blocks 11 on the fixing column 10 increase the pressure of the fixing rod on the soil to prevent the fixing column 10 from being inserted into the soil and unable to support the rear wheel of the tractor.

[0022] Embodiment 1, the described self-rescue device for a wheeled tractor stuck in the mud, when in use, fixes the fixing block 4 on the rear wheel of the tractor through the fixing rod 3, installs the fixing column 10 in the fixing sleeve 6 on the fixing block 4 and fixes and limits it through the threaded pin 8, and installs the limiting block 11 on the fixing column 10. When the rear wheel of the tractor rotates to drive the fixing column 10 to rotate, the length of the fixing column 10 is longer than the diameter of the rear wheel of the tractor. The fixing column 10 rotates and contacts the ground to support the rear wheel of the tractor, so as to help the tractor get out of the mud pit. The limiting block 11 on the fixing column 10 increases the pressure of the fixing rod on the soil to prevent the fixing column 10 from being inserted into the soil and unable to support the rear wheel of the tractor. The utility model has a reasonable and practical structure and is easy to install, is convenient for the tractor to get out of the mud pit, and improves the convenience of the tractor getting out of the mud pit.
