Description
Technical field
The utility model relates to a kind of track tension device, especially a kind of track tension device for combine.
Background technology
At present; the grain harvesting in rural area achieves automation substantially; wherein most important plant equipment is exactly combine; especially miniaturized track combine is more popular, but track combine after long-term use, and crawler belt usually there will be loosening; if can not place under repair timely and effectively; then probably cause security incident, not only delayed the harvesting of peasant's grain, also made the economic loss that the combine owner is huge.
Summary of the invention
The technical problems to be solved in the utility model is that existing track combine does not also possess conveniently track tension device.
In order to solve the problems of the technologies described above, the utility model provides a kind of track tension device of combine, comprises rectangular crawler body and level and is arranged on crossbeam in crawler body widthwise edges; The two ends of crossbeam are stretched out from the length edge of the crawler body left and right sides respectively, and are respectively equipped with a strainer on two external parts; Strainer comprises two sleeve pipes, clamping screw, push pedal, front nut, back nut, two push rods and regulating wheel; Two cover tube side-by-sides pass perpendicularly through crossbeam, and are fixed on crossbeam; Two push rods are inserted in two sleeve pipes respectively, and can pull and push back and forth along sleeve pipe; Push pedal is vertically mounted on one end of two push rods, and the two ends of the central shaft of regulating wheel respectively rotary type are arranged on the other end of two push rods, and regulating wheel stretches out the widthwise edges of crawler body; Clamping screw successively through push pedal and crossbeam, and screws mutually with front nut and back nut; Front nut and back nut lay respectively at the both sides of crossbeam.
Adopt clamping screw to promote push pedal, make two push rods limit regulating wheel all the time and be in tight state, can effectively prevent crawler belt from loosening, improve the safety and reliability that crawler belt uses; Before adopting, nut can match with back nut and realize the location of clamping screw, prevents clamping screw in the crawler belt course of work from loosening and retracts, guarantee that crawler belt no longer comes back to relaxed state; Adopt back nut can when keeping in repair easy adjustment rate of tension, only need turn back nut to realize fine adjustment, maintenance speed is fast, and can Field adjustment; Adopt two sleeve pipes be arranged side by side effectively can improve the stability of regulating wheel, prevent regulating wheel from occurring skew or crooked, improve the stability of regulating wheel.
In the widthwise edges of crawler body, also level is provided with a reinforcement, and reinforcement parallels with crossbeam, and two cover tube side-by-sides pass perpendicularly through reinforcement, and is fixed on reinforcement.Adopt built-in beam to be fixed two sleeve pipes further, further increase the stability of regulating wheel.
This beneficial effect is: (1) adopts clamping screw to promote push pedal, makes two push rods limit regulating wheel all the time and is in tight state, can effectively prevent crawler belt from loosening, and improves the safety and reliability that crawler belt uses; (2) before adopting, nut can match with back nut and realize the location of clamping screw, prevents clamping screw in the crawler belt course of work from loosening and retracts, guarantee that crawler belt no longer comes back to relaxed state; (3) adopt back nut can when keeping in repair easy adjustment rate of tension, only need turn back nut to realize fine adjustment, maintenance speed is fast, and can Field adjustment; (4) adopt two sleeve pipes be arranged side by side effectively can improve the stability of regulating wheel, prevent regulating wheel from occurring skew or crooked, improve the stability of regulating wheel.

Embodiment
As shown in Figure 1, the track tension device of combine of the present utility model, comprises rectangular crawler body 1 and level and is arranged on crossbeam 2 in crawler body 1 widthwise edges; The two ends of crossbeam 2 are stretched out from the length edge of crawler body 1 left and right sides respectively, and are respectively equipped with a strainer on two external parts; Strainer comprises two sleeve pipes 3, clamping screw 4, push pedal 5, front nut 6, back nut 7, two push rods 8 and can be embedded in the regulating wheel 9 in the gathering sill in the middle of crawler belt; Two sleeve pipes 3 pass perpendicularly through crossbeam 2 side by side, and are fixed on crossbeam 2; Two push rods 8 are inserted in two sleeve pipes 3 respectively, and can pull and push back and forth along sleeve pipe 3; Push pedal 5 is vertically mounted on one end of two push rods 8, and the two ends of the central shaft of regulating wheel 9 respectively rotary type are arranged on the other end of two push rods 8, and regulating wheel 9 stretches out the widthwise edges of crawler body 1; Clamping screw 4 successively through push pedal 5 and crossbeam 2, and screws mutually with front nut 6 and back nut 7; Front nut 6 and back nut 7 lay respectively at the both sides of crossbeam 2; In the widthwise edges of crawler body 1, also level is provided with a reinforcement 10, and reinforcement 10 parallels with crossbeam 2, and two sleeve pipes 3 pass perpendicularly through reinforcement 10 side by side, and is fixed on reinforcement 10.
Track tension device of the present utility model in use, if the crawler belt of combine occurs lax, then first front nut 6 is unclamped a segment distance, again by spanner turn back nut 7, make clamping screw 4 pull push pedal 5 to move to crossbeam 2 place, now regulating wheel 9 will withstand crawler belt forward, crawler belt is tightened again, finally more front nut 6 is screwed, make clamping screw 4 be fixed on crossbeam 2 firmly, after having regulated the crawler belt of side, continue the crawler belt regulating opposite side as required.
