DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-7 The utility model provides a technical solution: a driving wheel of a rubber half-track for a crawler harvester, comprising a driving wheel 1, a crawler 2 is sleeved on the outer surface of the driving wheel 1, and a driving shaft 3 is fixedly arranged at the middle part of the inner side of the driving wheel 1; a cutting mechanism for cleaning entangled weeds is arranged between the driving shaft 3 and the driving wheel 1; the cutting mechanism comprises a slide groove 4, a slider 5, a cutting knife 6, a through groove 7, a moving block 8, and a connecting rod 9; a slide groove 4 is opened on the outer surface of the driving shaft 3, a slider 5 is movably engaged with the inside of the slide groove 4, a cutting knife 6 is fixedly arranged on the upper end and both sides of the slider 5, a through groove 7 is opened at the upper end of the driving shaft 3 inside the driving wheel 1, a moving block 8 is arranged inside the through groove 7, and a connecting rod 9 is fixedly arranged on the outer surface of the slider 5.

[0024] A moving block 8 is provided inside the through groove 7 by screwing; the moving block 8 is provided inside the through groove 7 by screwing; so that when the moving block 8 is rotated, the moving block 8 can move left and right along the through groove 7 under the action of the screw; so that the slider 5 and the cutting knife 6 can be driven to move left and right along the slide groove 4; so that the weeds wound around the surface of the driving shaft 3 can be cut off;

[0025] The movable block 8 is provided with a slot 10 inside, and a connecting ring 11 is fixedly provided at one end of the connecting rod 9 close to the movable block 8; the connecting ring 11 is movably engaged and arranged inside the slot 10; the purpose of the slot 10 and the connecting ring 11 is that since the movable block 8 is arranged inside the through groove 7 by a thread, the movable block 8 needs to rotate when it moves left and right; and the movable block 8 and the connecting rod 9 are fixed together by the slot 10 and the connecting ring 11; the rotation of the movable block 8 can be avoided; at the same time, when the movable block 8 moves left and right, the connecting rod 9 can also be driven to move left and right together; it can be simply understood that under the action of the slot 10 and the connecting ring 11, the movable block 8 can rotate freely and can drive the connecting rod 9 to move left and right;

[0026] A twisting block 12 is fixedly provided on one side of the surface of the moving block 8; the moving block 8 can be easily rotated by twisting the block 12; it should be noted that the moving block 8 of the device needs to be rotated by a socket wrench; in this way, the moving block 8 can be easily rotated even if it is inside the through slot 7 under the action of the socket wrench;

[0027] The outer surface of the driving wheel 1 is evenly and fixedly provided with a plurality of latch teeth 13; the inner side wall of the crawler 2 is provided with a limiting groove 14; the latch teeth 13 are arranged in the limiting groove 14; the crawler 2 can be driven to move when the driving wheel 1 rotates through the latch teeth 13;

[0028] The outer surface of the driving wheel 1 is fixed with a limit baffle 15 by bolts; the limit baffle 15 can limit the crawler 2, so that the crawler 2 cannot move left and right in a large range, thereby preventing the limit groove 14 from being separated from the latch 13; when the driving wheel 1 needs to be manually disassembled, first loosen the fixing screws of the limit baffle 15; remove the limit baffle 15 first;

[0029] Working principle: When using the device, the drive shaft 3 is inserted into the middle of the drive wheel 1 through the star-shaped latch 13; then one end of the drive shaft 3 is connected to the output shaft end of the hydraulic motor; in this way, the hydraulic motor can be used to drive the drive shaft 3 and the drive wheel 1 to rotate; and a fixing bolt should be provided between the end of the drive shaft 3 away from the hydraulic motor and the drive wheel 1 to prevent the drive shaft 3 and the drive wheel 1 from being laterally separated;

[0030] When the device is subsequently used, the limiting baffle 15 is limited on both sides of the limiting groove 14, thereby limiting the crawler 2, making it impossible for the crawler 2 to move left and right over a large range, thereby preventing the limiting groove 14 from being separated from the latching tooth 13.

[0031] And when the device is in use, if weeds, rice straws and other debris are entangled on the surface of the driving shaft 3, no matter how the weeds and rice straws are entangled, they will inevitably be entangled on the outside of the sliding groove 4 and will not hinder the movement of the sliding block 5. At this time, a socket wrench can be set on the outer surface of the twisting block 12; then the twisting block 12 can be rotated to drive the moving block 8 to move; and when the moving block 8 moves, the connecting rod 9 can drive the sliding block 5 to move left and right inside the sliding groove 4; at this time, the cutter head can cut off the weeds entangled on the surface of the driving shaft 3; in this way, the weeds, straws and other debris entangled on the surface of the driving shaft 3 can be conveniently cut off and removed at any time; the whole removal process is convenient and quick.
