Description

Technical Field

[0001] The utility model belongs to the technical field of subsoilers, and particularly relates to the overall structure of a spiral subsoiler. Background Technique

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] A subsoiler is a device used for deep tillage and loosening of soil. It drives the spiral blades of the working part to penetrate deep into the soil layer to stir the soil layer, and at the same time drives the walking part to achieve deep tillage operation of the land.

[0004] In the prior art, in the technical solution disclosed in Patent CN220874989U, the subsoiler is equipped with two engines. One is installed on one side of the cab to provide the driving force for the whole vehicle to move, and the other is installed in the middle of the subsoiler to provide power for the rotating mechanism and the flipping mechanism of the working part. A fuel tank is installed between the two engines.

[0005] The overall layout of this subsoiler first leads to a relatively large overall self-weight of the subsoiler due to the need to install two engines, thus resulting in a large power demand for movement; secondly, setting a fuel tank between the two engines will cause the fuel tank temperature to be too high and the endurance to be insufficient; then, only using a lifting oil cylinder to control the flipping of the working part cannot change the operation depth of the subsoiler; finally, since the cab is set on one side, the field of vision is limited, and the safety and accuracy of the traveling route cannot be guaranteed during operation. At the same time, the cab being adjacent to the engine also has safety risks. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] The utility model is described in detail below in conjunction with the accompanying drawings. The present embodiment discloses a spiral deep tiller vehicle structure, such as Figure 1 As shown, it includes a frame 1, an engine 2 is arranged in the middle of the upper middle part of the frame 1, a fuel tank 3 is fixed on each side of the upper middle part of the middle part of the frame 1, a cab 4 is arranged on the upper front end of the frame 1, a frame crossbeam is fixed on the upper rear end of the frame 1, and the rear end of the frame 1 is hinged to the turning frame 10; the working component 5 is connected to the turning frame 10 and the frame 1 through a hydraulic transmission mechanism 6; the engine 2 provides power for the working component 5 and the hydraulic transmission mechanism 6, and the engine 2 provides power for the travel drive mechanism.

[0031] In this embodiment, the power output of the engine 2 includes a flywheel end and two power take-off ports, each of which is equipped with a PTO power take-off device; Figure 2 As shown, the flywheel end of the engine 2 is connected to one end of the main power transmission mechanism 7, and the other end of the main power transmission mechanism 7 is connected to the working component 5. The working component 5 includes a reduction box 51, which is arranged on the top of the gear transfer box 52, and the reduction box 51 is connected to the gear transfer box 52. The bottom of the gear transfer box 52 is rotatably connected to multiple knife shafts, and the gear transfer box 52 can drive multiple knife shafts to rotate synchronously or stop at the same time. It can be understood that the gear transfer box 52 and the reduction box 51 are both based on the existing technology, wherein the number of connections between the gear transfer box 52 and the knife shaft is independently set according to the actual situation.

[0032] like Figure 2 As shown, in this embodiment, the main power transmission mechanism 7 passes through the frame crossbeam at the rear end of the frame 1, one end is connected to the reduction box 51, and the other end is connected to the flywheel end of the engine 2 through a clutch. This is because when the operator shifts gears or performs emergency braking, the clutch can temporarily cut off the connection between the engine 2 and the reduction box 51, which can reduce the impact on the reduction box 51 and prevent overload.

[0033] like Figure 1 , 2As shown in the figure, the hydraulic transmission mechanism 6 includes a tipping cylinder 61 and a lifting cylinder 62; the bottom end of the tipping frame 10 is hinged to the rear end of the vehicle frame 1, and the top end of the tipping frame 10 is hinged to the vehicle frame cross beam at the rear end of the vehicle frame 1 through the tipping cylinder 61; the lifting cylinder 62 is arranged between the tipping frame 10 and the gear transfer case 52, and the tipping frame 10 is slidably connected to the gear transfer case 52 through the lifting cylinder 62. It can be understood that since the working component 5 is connected to the tipping frame 10, the tipping cylinder 61 can drive the working component 5 to flip relative to the vehicle frame 1, and the lifting cylinder 62 drives the working component 5 to lift and lower relative to the vehicle frame 1.

[0034] In this embodiment, since a lifting cylinder is added to the tipping frame to connect the working components, the working component can move up and down relative to the vehicle frame, and the adjustment of the working depth of the subsoiler can be realized.

[0035] As Figure 2 shown in the figure, two power take-off ports of the engine 2 are respectively connected with a hydraulic piston pump 8 and a gear pump 9; wherein the hydraulic piston pump 8 provides power for the traveling drive mechanism, and the gear pump 9 provides power for the hydraulic transmission mechanism 6. It can be understood that both the hydraulic piston pump 8 and the gear pump 9 are fixed on the vehicle frame 1 through connecting parts, and the connecting parts can be U-shaped clamps and bolts.

[0036] As Figure 3 shown in the figure, the traveling drive mechanism includes a front axle 81 and a rear axle 82 arranged at the bottom of the vehicle frame 1. The front axle 81 is connected to the speed change adjustment device 85 through the front transfer drive shaft 83, and the rear axle 82 is connected to the speed change adjustment device 85 through the rear transfer drive shaft 84. The speed change adjustment device 85 is connected to the output end of the hydraulic motor 86; the hydraulic motor 86 is connected to the hydraulic piston pump 8. The hydraulic piston pump 8 can convert mechanical energy into hydraulic energy. One end of the hydraulic piston pump 8 is connected to the fuel tank 3 through a hydraulic pipeline, and the other end transmits the hydraulic oil in the fuel tank 3 to the hydraulic motor 86 through a high-pressure hydraulic pipeline to drive the hydraulic motor 86 to rotate, and then convert the hydraulic energy into mechanical energy again. It can be understood that both the speed change adjustment device 85 and the hydraulic motor 86 are fixedly connected to the vehicle frame 1 through corresponding fixing connecting parts.

[0037] The speed change adjustment device 85 includes a torque converter and a gearbox, and its function is to reduce the speed and increase the torque of the power from the hydraulic motor 86, and then transmit it to the front transfer drive shaft 83 and the rear transfer drive shaft 84; it can be understood that the speed change adjustment device 85 is connected to the front transfer drive shaft 83 and the rear transfer drive shaft 84 through a transfer case, and can distribute the power output by the speed change adjustment device to the front axle and the rear axle, so as to drive the vehicle to move forward. It can be understood that the speed change adjustment device 85 can adopt the existing technology, and the speed change adjustment device has 2-4 gears with different speed ratios to meet the different speed requirements during work and transfer.

[0038] In this embodiment, the hydraulic piston pump and the hydraulic motor both adopt the prior art. The hydraulic piston pump is a two-way variable pump that can adjust and reverse the flow direction of the internal hydraulic oil. The hydraulic motor connected to the hydraulic piston pump can also change the rotation direction according to the switching of the hydraulic oil flow direction.

[0039] By changing the flow direction of the hydraulic oil inside the hydraulic piston pump 8, the rotation direction of the hydraulic motor 86 is further changed, so that the hydraulic motor 86 switches from forward rotation to reverse rotation, thereby enabling the control of the vehicle to move forward or backward, and eliminating the need to separately set a reverse gear for the vehicle.

[0040] As Figure 3 shown, the axis of the front axle 81 is parallel to the axis of the rear axle 82. Front wheels 811 are respectively provided at both ends of the front axle 81, and the front wheels 811 are rotatably connected to the front axle 81. Rear wheels 821 are respectively provided at both ends of the rear axle 82, and the rear wheels 821 are rotatably connected to the rear axle 82. It can be understood that the front axle, the front wheels, the rear axle, and the rear wheels also have the function of shock absorption.

[0041] As Figure 2 shown, another power take-off port of the engine 2 provides mechanical power for the gear pump 9, which can convert mechanical energy into hydraulic energy. One end of the gear pump 9 is connected to the fuel tank 3, and the other end is connected to the tipping cylinder 61 and the lifting cylinder 62 of the hydraulic transmission mechanism 6 through a hydraulic pipeline. The tipping cylinder 61 can control the tipping of the tipping frame 10 relative to the vehicle frame 1, thereby driving the working component 5 to tip relative to the vehicle frame 1. The lifting cylinder 62 can drive the working component 5 to lift and lower relative to the vehicle frame 1; the gear pump 9 is also connected to the clutch cylinder through a hydraulic pipeline. The piston of the clutch cylinder is connected to the clutch, and the connection and disconnection of the clutch can be controlled through the clutch cylinder.

[0042] The principle is as follows: when the gear pump 9 supplies hydraulic oil to the clutch cylinder, the piston of the clutch cylinder extends under the action of the hydraulic oil pressure, separating the clutch disc from the flywheel; when the gear pump 9 no longer supplies hydraulic oil to the clutch cylinder, the pressure inside the clutch cylinder disappears, the piston retracts, and the clutch disc engages with the flywheel.

[0043] In summary, it is not difficult to find that in this embodiment, only one engine can provide the operating power for the working components, the hydraulic transmission mechanism, and the traveling drive mechanism of the subsoiler, making the use space of the vehicle frame more reasonable, the overall self-weight of the subsoiler lighter, and reducing its moving power requirement.

[0044] As Figure 1 shown, a counterweight 41 is installed at the lower part of the front end of the vehicle frame 1 for adjustment according to the center of gravity position of the whole vehicle, making the weight distribution of the whole vehicle more reasonable; as Figure 2 shown, the two fuel tanks 3 fixed on both sides of the vehicle frame 1 are fixed to the vehicle frame 1 by a plurality of hoop members and bolts.

[0045] In this embodiment, since only one engine needs to be installed on the upper part of the middle section of the vehicle frame, the cab 4 is integrally arranged at the front end of the deep tillage tractor vehicle frame 1, with a wide field of vision, which can facilitate the operator to drive the deep tillage machine to control its traveling route and further ensure the safety of the deep tillage machine during the operation process; there is an operating platform in the cab, and the operator can control the operation of the tillage equipment through the operating platform.

[0046] It can be understood that a scraper and a press roller are arranged behind the working component 5. The scraper is used to level the ground after the working component 5 has carried out deep tillage, and the press roller can further compact the leveled ground. As Figure 1 shown, a heat dissipation mechanism is also arranged between the cab and the engine. A partition is installed on the heat dissipation mechanism, so that cold air enters the heat dissipation mechanism from the front, and hot air can also be discharged from the heat dissipation fan to the rear of the vehicle body, ensuring that the engine will not overheat; ensuring the stable heat dissipation operation of the engine.

[0047] Two fuel tanks are arranged on the vehicle frame on both sides of the engine, which can improve the endurance of the whole vehicle. And the heat dissipation mechanism of the engine is arranged between the cab and the engine, so that the heat will not spread to both sides of the engine, preventing the fuel tank from having too high a temperature; and it can also ensure the safety of the cab.

[0048] Although the specific implementation manners of the present invention have been described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
