For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that have been explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or apparatuses, or steps or units that are added based on further optimization schemes conceived by the present invention.

[0032] like Figure 1-Figure 4 As shown, a field tillage tractor stuck in the field self-rescue device disclosed by the utility model includes a fixing member 1 and a supporting member 2. The fixing member 1 is fixedly connected to the wheel hub of the tractor wheel. The supporting member 2 is a telescopic structure. The supporting member 2 is fixedly connected to the fixing member 1, and the telescopic direction of the supporting member 2 is along the diameter direction of the tractor wheel hub. A locking mechanism 23 is provided on the supporting member 2 for limiting the telescopic movement of the supporting member 2.

[0033] The fixing member 1 can be directly fixedly mounted on the wheel hub, or can be detachably mounted on the wheel hub, and the support member 2 can also be connected to the fixing member 1 in a fixed or detachable manner;

[0034] The support member 2 is a telescopic structure. The fixing member 1 and the support member 2 are installed on the two driving wheels of the tractor through the fixing member 1. When the wheel sinks into the mud, the support member 2 is extended to a suitable length, and then the wheel is rotated, and the end of the support member 2 away from the wheel is supported on the ground, and the tire of the tractor sunk into the mud is propped up with the ground as a fulcrum, and then the wheel is rotated to move forward.

[0035] The fixed connection between the fixing member 1 and the tractor wheel hub is a detachable fixed connection.

[0036] Furthermore, the fixing member 1 includes a cylindrical first connecting member 11 and a second connecting member 12 arranged at one end of the opening of the first connecting member 11, the second connecting member 12 is a sheet-like steel ring structure, the inner diameter of the second connecting member 12 is the same as the outer diameter of the first connecting member 11, and the first connecting member 11 is fixedly connected to the second connecting member 12, and a positioning hole 13 corresponding to the wheel hub bolt hole is provided at one end of the first connecting member 11 away from the second connecting member 12, and the first connecting member 11 is connected to the wheel hub through the hub bolts.

[0037] The first connecting member 11 and the second connecting member 12 are both made of iron, and the first connecting member 11 and the second connecting member 12 need to be set to a certain thickness to ensure that they can support the weight of the tractor without deformation after the tractor body is tilted with the unsunk wheel as the fulcrum;

[0038] The positioning hole 13 formed on the first connecting member 11 corresponds to the position of the hub bolt on the wheel hub. When installing, first remove the hub bolt, then attach the first connecting member 11 to the wheel hub, and make the positioning hole 13 correspond to the hub bolt hole, then install the hub bolt, fix the wheel and fix the first connecting member 11 of the fixing member 1 to the wheel, thereby installing the fixing member 1;

[0039] It should be noted that whether to install the fixing member 1 and the supporting member 2 can be determined based on observing the terrain in advance to prevent the wheels from sinking into the mud and making installation inconvenient; or the wheels can be installed in real time after sinking into the mud.

[0040] The first connecting member 11 is a cylindrical tube structure, and a second connecting member 12 with a flange is fixed to one end thereof, and is installed with the wheel hub through the flange.

[0041] like Figure 7 and Figure 8 As shown, in another embodiment, the first connecting member 11 may also be a square cylindrical structure, and is a rectangular parallelepiped structure in the figure.

[0042] The first connecting member 11 may also be set as a solid structure, which can further improve the strength of the first connecting member 11. Especially for large tilling machines, which are heavy, the first connecting member 11 is easily deformed by force. By setting an integrated first connecting member 11 structure, its supporting strength is guaranteed;

[0043] A high-strength metal material may also be used, and a paint may be sprayed on the surface to prevent rust and increase the service life. A reinforcing rib may also be provided inside the first connecting member 11 to increase the strength of the first connecting member 11.

[0044] When manufacturing the first connecting member 11, its load-bearing capacity needs to be considered and its load-bearing capacity needs to be tested in advance. The thickness of the first connecting member 11 can be increased or structures such as reinforcing ribs can be provided.

[0045] Furthermore, the first connecting member 11 and the second connecting member 12 are fixed by welding.

[0046] Furthermore, the first connecting member 11 and the second connecting member 12 are integrally provided.

[0047] The first connecting member 11 and the second connecting member 12 are configured as an integrated structure to increase the overall strength of the fixing member 1 and prevent deformation and damage that affect use.

[0048] The support member 2 includes a fixed rod 21 and a movable rod 22 . The fixed rod 21 is connected to the first connecting member 11 . The movable rod 22 is inserted into the fixed rod 21 , and the movable rod 22 is slidably connected to the fixed rod 21 . The locking mechanism 23 is used to lock or release the movable rod 22 .

[0049] The above-mentioned fixed rod 21 and movable rod 22 are made of iron material, and the fixed rod 21 and movable rod 22 are set to be slidingly connected. The movable rod 22 can slide and retract along the fixed rod 21. A locking mechanism 23 is set on the fixed rod 21, so that the sliding rod slides to a suitable position and can be locked by the locking mechanism 23 so that it no longer slides, so as to avoid sliding during the self-rescue process and affecting the use.

[0050] The fixed connection between the fixing rod 21 and the first connecting member 11 is a detachable fixed connection.

[0051] Two through holes 3 are provided on the side wall of the first connecting member 11, and the angle between the two through holes 3 (i.e., on the opposite sides of the side wall of the first connecting member) is 180°. The shape of the through holes 3 is adapted to the shape of the fixing rod 21. Two mounting holes 4 are provided at positions corresponding to the two through holes 3 on the second connecting member 12, and a connecting hole 5 is provided at a position corresponding to the mounting hole 4 on the fixing rod 21. The second connecting member 12 and the fixing rod 21 are fixed by mounting bolts through the mounting holes 4 and the connecting holes 5.

[0052] The fixing rod 21 and the first connecting member 11 are fixed with bolts to further increase convenience. The fixing member 1 can be installed on the wheel first, and then the fixing rod 21 of the supporting member 2 can be installed when self-rescue is needed;

[0053] At the same time, the support member 2 is also configured as a detachable structure, so that after each self-rescue, the support member 2 can be disassembled to clean the dirt on the support member 2 to prevent the support member 2 from rusting and affecting sliding.

[0054] The locking mechanism 23 includes a pin rod, and a pair of opposite side walls of the fixed rod 21 away from the end of the fixed part 1 are each provided with a limiting hole 231, and a plurality of pin holes 232 are evenly spaced on the side walls of the movable rod 22 corresponding to the two limiting holes 231. A limiting pin 233 is provided in the limiting hole 231 and is threadedly connected to a limiting member 234 on the limiting pin 233. The limiting member 234 is provided at one end of the limiting pin 233, and a limiting block 235 larger than the size of the limiting hole 231 is provided at the other end of the limiting member 234.

[0055] The locking mechanism 23 mentioned above is inserted into the limiting hole 231 and the pin hole 232 by the limiting pin 233, and adjusts different pin holes 232 to lock the telescopic length of the fixed rod 21 and the movable rod 22, and makes real-time adjustments according to the depth of the wheel sinking.

[0056] The utility model utilizes the power of the vehicle itself to rotate the wheels, so that the telescopic support member 2 is inserted into the mud pit, and the vehicle itself is lifted up to achieve the effect of self-rescue and escape from difficulties.

[0057] like Figure 5 and Figure 6 As shown, in another embodiment, a slide groove 6 is opened along the axial direction of the side wall of the first connecting member 11 on the side where the fixing rod 21 supports the ground, and the other end of the fixing rod 21 is hinged to the first connecting member 11, and at least two ear plate groups 7 are arranged at intervals on both sides of the slide groove 6, and the fixing rod 21 is connected to the ear plate group 7 by a screw, and screw holes are arranged at intervals on the fixing rod 21, and the screw holes are arranged at the position corresponding to each ear plate group 7 when the fixing rod 21 rotates around the hinge point.

[0058] The detachable fixed connection between the fixing rod 21 and the first connecting member 11 is specifically as follows: the fixing rod 21 is installed on the first connecting member 11, one end of which extends far out of one side of the first connecting member 11, and the side serves as one end of the fixing rod 21 support, and the other end of the fixing rod 21 is hinged to the first connecting member 11 through a pin (ear plate), a limiting cap is provided at one end of the pin, and a nut is threadedly connected to the other end to limit the pin;

[0059] A slide groove 6 is provided on one side of the first connecting member 11 supported by the fixing rod 21 along the axial direction of the first connecting member 11. The fixing rod 21 rotates around the pin shaft, and the other side can slide in the slide groove 6. At least two groups of ear plate groups 7 are provided on both sides of the slide groove 6 (each ear plate group 7 is composed of two left and right ear plate groups 7). In this embodiment, three ear plate groups 7 are provided. When the fixing rod 21 rotates to positions corresponding to the three ear plate groups 7, corresponding screw holes are provided on the fixing rod 21, so as to fix the fixing rod 21 by passing a bolt assembly between the screw hole and the ear plate group 7 after the fixing rod 21 rotates to a suitable position.

[0060] It should be noted that the first ear plate group 7 (the ear plate group 7 installed on the side of the wheel hub close to the wheel hub) corresponds to the ear plate at the hinge point of the fixed rod 21, so that the fixed rod 21 is parallel to the vehicle body at this position, and when the fixed rod 21 slides in the slide groove 6 (rotates around the hinge point), the fixed rod 21 gradually tilts away from the vehicle body (away from the vehicle body to the outside), so that during the tilling process of the tiller, the support of the fixed rod 21 and the ground can be away from the tiller to avoid interference with the rotary tiller behind the tiller.

[0061] Especially for long sections of muddy roads, the fixing rod 21 can be fixed to one side of the wheel and tilted toward the side away from the wheel. During the forward movement of the wheel, the rotation of the fixing rod 21 will not affect the operation of the rotary tiller at the tail of the tiller, thereby ensuring the working efficiency of the tiller and avoiding repeated disassembly or retraction of the fixing rod to affect the working efficiency.

[0062] In addition, the plurality of ear plate groups 7 may also be a whole ear plate, and a plurality of holes are provided at intervals on the whole ear plate to fix the fixing rod 21 .

[0063] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0064] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0065] The above is a relatively specific and detailed description of the utility model through general description and specific embodiments. It should be pointed out that, without departing from the concept of the utility model, it is obvious that several variations and improvements can be made to these specific embodiments, which all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be based on the attached claims.
