Detailed implementation mode
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a driving harrow with a gearbox oil liquid air-cooled radiator, including a driving harrow 1 and an air-cooled radiator 6. The housing of the driving harrow 1 is installed with a gantry 5 through a lower hanging bracket 15. A support plate 13 is installed at the rear end of the gantry 5, and the air-cooled radiator 6 is installed on the support plate 13. The rear end of the housing of the driving harrow 1 is connected to the support plate 13 through a reinforcing plate to ensure the support effect on the air-cooled radiator 6. Since the gantry 5 is bow-shaped, there are two air-cooled radiators 6 and they are symmetrically arranged.
[0024] A gear pump 7 is installed on the housing of the driving harrow 1. The gear pump 7 is the power source for the oil liquid circulation. The air-cooled radiator 6, the gear pump 7 and the gearbox of the driving harrow 1 are connected through an oil pipe 14. The liquid inlet end of the oil pipe 14 is arranged at the bottom of the gearbox, and the liquid outlet end of the oil pipe 14 is arranged at the top of the bottom of the gearbox to ensure good cooling effect on the oil liquid.
[0025] The gear pump 7 is matched with the gearbox of the driving harrow 1. The specific matching method is that a driven gear 9 is provided at the power input end of the gear pump 7. An extension section 11 is provided at the top of any output shaft of the gearbox of the driving harrow 1, and a driving gear 10 is provided on the extension section 11, and the driving gear 10 is meshed with the driven gear 9. The gear pump 7 is driven by the self-power of the gearbox, and the circulation of the oil liquid can be completed without connecting an external oil pump.
[0026] A traction plate 3 is installed on the driving harrow 1. The upper rear end of the traction plate 3 is rotatably connected with a hydraulic cylinder 4. The output end of the hydraulic cylinder 4 is rotatably connected to a pressing roller 2, and the pressing roller 2 is rotatably connected to the lower rear end of the traction plate 3.
[0027] During the process of the driving harrow 1 moving forward, the pressing roller 2 presses the turned-up soil. By adjusting the output length of the hydraulic cylinder 4, the contact pressure between the pressing roller 2 and the soil can be changed, thereby adjusting the pressing effect.
[0028] Working principle: In the state of long-term tilling, the temperature of the hydraulic fluid in the gearbox of the driving harrow 1 will change significantly. If heat dissipation cannot be carried out in time, the safety of the internal components of the gearbox will be seriously affected. By setting up an air-cooled radiator 6, the heated hydraulic fluid is cooled. However, if an independent pump is set up, it will not only increase the load-bearing burden of the driving harrow 1, but also cause interference between various components. By connecting the gearbox of the driving harrow 1 to the gear pump 7 through gears, the driving of the gear pump 7 is realized, thereby realizing the circulation of the hydraulic fluid. Without the need for external equipment, the cooling of the gearbox oil can be completed.
[0029] Please refer to Figure 5 , the present utility model also provides another technical solution: A subsoiling mechanism 8 is installed at the lower end of the gantry 5. The subsoiling mechanism includes a pair of brackets 81, a plurality of front subsoiling hooks 82 and a plurality of rear subsoiling hooks 83. The pair of brackets 81 are installed at the lower end of the gantry 5 and penetrate and are fixedly arranged on the lower hanging frame 15 to ensure the stability of the connection. A plurality of the front subsoiling hooks 82 and a plurality of the rear subsoiling hooks 83 are respectively installed on the pair of brackets 81 through an assembly mechanism. The assembly mechanism includes a pair of clamping plates 12. Symmetrically arranged mounting holes are provided on the pair of clamping plates 12. Subsoiling hook holes are vertically opened on the front subsoiling hooks 82 and the rear subsoiling hooks 83, and the number of subsoiling hook holes is greater than that of the mounting holes. The subsoiling hook holes and the mounting holes are connected through fasteners. Since the number of subsoiling hook holes is large, the operator can select the installation height of the front subsoiling hooks 82 and the rear subsoiling hooks 83 according to actual needs, and thus specifically select the plowing depth according to the soil conditions.
[0030] To ensure the plowing effect, the front subsoiling hooks 82 and the rear subsoiling hooks 83 are arranged at equal intervals on each bracket 81, and the front subsoiling hooks 82 and the rear subsoiling hooks 83 respectively installed on the pair of brackets 81 are arranged staggeredly.
