Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation vehicles, and in particular relates to a parking linkage structure for a towed irrigation vehicle. Background Art

[0002] In the field of irrigation vehicle technology, irrigation vehicles usually adopt a towing structure, that is, the front side is a traction vehicle, and the rear end is a traction hose retraction device. The hose is retracted and released by moving the vehicle forward, thereby delivering water to the irrigation point.

[0003] The technical problem currently encountered is that when the traction vehicle moves forward, it drags the irrigation vehicle to move synchronously, but when the traction vehicle stops, the hose retracting and releasing drive device on the irrigation vehicle must receive a stop signal synchronously, that is, when the traction vehicle stops, the hose retracting and releasing drive device on the irrigation vehicle stops rotating synchronously. In the prior art, this synchronous stop function is mostly achieved by manual operation by operators or by electronic control components. The disadvantages of these two methods are: manual operation requires two people to operate synchronously, and a single person cannot operate, resulting in two people having to cooperate synchronously when the equipment is running, which takes up a lot of manpower and has poor efficiency; because the equipment is used in the field, the electronic control components have poor stability in harsh environments, high failure rate, and need to be replaced regularly after years of use, with high maintenance costs.

[0004] In view of the drawbacks of the existing technology, as a researcher in this field, the technical problem that needs to be solved is: to design a mechanical parking linkage structure for a towed irrigation vehicle, so as to achieve synchronous drive when the towing vehicle stops, and to avoid disorderly driving of the hose retraction and extension drive device causing the hose to be retracted too long and affect the irrigation operation. Summary of the invention

[0005] In view of the shortcomings of the prior art mentioned above, the utility model proposes a parking linkage structure for a trailer irrigation vehicle, which is provided with a linkage drive structure, utilizes inertia to realize the force of the driving rod, applies force to the driving module through the driving rod to realize clutch linkage, and then accurately controls the hose retracting and extending driving device.

DETAILED DESCRIPTION

[0024] The present invention is further described below through an implementation method. As shown in the accompanying drawings, the following description is only an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The protection scope of the parking linkage structure of the trailer irrigation vehicle shall be based on the scope recorded in the claims.

[0025] Embodiment 1:

[0026] A parking linkage structure for a trailer irrigation vehicle comprises a traction frame 1, a retractable frame 2 is arranged on the top surface of the traction frame 1, a retractable tube driving device 21 is arranged on the side of the retractable tube driving device 21, and a clutch shaft 22 is arranged on the top surface of the retractable tube driving device 21.

[0027] An oblique extension frame 4 is disposed at the front end of the storage frame 2 . A horizontal adjustment seat 9 is disposed on the oblique extension frame 4 . A horizontal adjustment slot 91 is disposed in the horizontal adjustment seat 9 .

[0028] The front end of the inclined extension frame 4 is also provided with a horizontal hinge seat 57, and a driving frame 6 is hingedly connected through the horizontal hinge seat 57. A front end driving rod 8 is hingedly provided on the driving frame 6. The tail end of the front end driving rod 8 is fixed in a horizontal adjustment slot 91 in a horizontal adjustment seat 9. The front end driving rod 8 and the rear end driving rod 81 are hinged in the horizontal adjustment slot 91 through a hinge shaft 92 and are constrained in the horizontal adjustment slot 91 to only realize horizontal movement. A clamping spring 93 is also provided between the hinge shaft 92 and the horizontal adjustment seat 9. The clamping spring 93 squeezes the hinge shaft 92 to give it a certain clamping force, thereby preventing the front end driving rod 8 and the rear end driving rod 81 from being hinged and loose in the horizontal adjustment slot 91.

[0029] The rear end driving rod 81 is connected to the clutch shaft 22 on the retractable tube driving device 21 and performs clutch driving on it.

[0030] The driving frame 6 is a U-shaped frame. When it is used, when the traction vehicle drives the traction frame 1 to move forward, and the traction vehicle reaches the specified position and stops, the traction frame 1 is still moving forward due to inertia. At this time, the driving frame 6 touches the traction vehicle and flips upward. At this time, the front end driving rod 8 hinged on the driving seat 61 drives the rear end driving rod 81 to apply force to the clutch shaft 22 on the rear side to realize clutch drive, thereby realizing the drive stop of the retractable frame 2.

[0031] After the above structure is set, after the equipment stops running, in order to ensure the stability of the clutch lock of the retractable pipe driving device 21, the parking linkage structure of the trailer irrigation vehicle also realizes a secondary positioning structure, as follows: Figure 2 As shown, the oblique extension frame 4 is provided with a hinge plate 41, and the hinge plate 41 is hinged with a positioning rod 7. The front end of the positioning rod 7 is provided with a slot piece 74, and a slot with a right-angle structure is formed at the junction of the slot piece 74 and the positioning rod 7. The positioning rod 75 is fixed by the slot. The positioning rod 75 is a rod body inserted into the driving frame 6. Through this structure, the driving frame 6 can be prevented from loosening when the clutch is applied, thereby avoiding clutch failure.

[0032] Furthermore, in order to prevent the positioning rod 7 from falling and affecting the normal travel of the traction frame 1 when the positioning rod 7 is in a non-positioning state, a swing support portion 72 is provided on the hinged plate 41 of the parking linkage structure of the trailer irrigation vehicle. The swing support portion 72 can be a rod body or a protrusion for supporting the positioning rod 7. The purpose is to prevent the positioning rod 7 from falling without restraint and to limit the swing of the positioning rod.

[0033] The positioning rod 7 is also provided with a pulling seat 73, through which a single end of a pulling limit rope 76 is fixed, and the other end of the pulling limit rope 76 is connected to the positioning rod 75, and the positioning rod 75 is fixed on the driving frame 6, and the pulling limit rope 76 is used to realize the pulling limit of the driving frame 6 by the positioning rod 7. This structure limits the lowest position of the driving frame 6 to prevent it from falling to the ground and affecting the normal driving of the traction frame 1.

[0034] The utility model also has the function of extending support, and the specific disclosed structure is as follows: the interior of the inclined extension frame 4 is a hollow structure, and an extension rod 5 is arranged inside it. The end of the extension rod 5 is vertically provided with a ground support seat 55 through a locking seat 56, and the traction frame 1 is supported on the ground surface through the ground support seat 55.

[0035] like Figure 3 As shown, a driven toothed belt 51 is provided on the bottom surface of the extension rod 5, and a driving gear 52 is also provided in the inclined extension frame 4 to mesh with the driven toothed belt 51. A driving rod 53 is provided at the axis of the driving gear 52 and extends to the outside of the inclined extension frame 3. The driving rod 53 is connected to an external driving handle or a driving motor. The driving handle or the driving motor drives the driving rod 53 to rotate, thereby realizing the rotation of the driving gear 52 and driving the driven toothed belt 51. This structure can realize the outward extension drive of the extension rod 5 and realize stable support of the entire traction frame 1 on the ground at different heights.

[0036] After the extension rod 5 is telescopically driven and its extension amount is fixed, the positioning device must be used to ensure its stability. The positioning structure disclosed in the utility model is as follows: a plurality of external positioning holes are provided on the inclined extension frame 4, and a plurality of internal positioning holes are provided on the extension rod 5. The external positioning holes and the internal positioning holes are connected by a plug-in rod 54 to achieve extension positioning. The plug-in rod 54 can be fixed to the inclined extension frame 4 by a steel cable or a rope, and can be used at hand during positioning, which is more convenient for the operator to perform positioning operations.

[0037] In summary, the utility model adopts the above structural setting. When the towing vehicle stops, the towing frame continues to move forward by inertia to push the driving frame 6 to squeeze with the towing vehicle, and the driving frame 6 flips up and pushes the front driving rod 8 and the rear driving rod 81 to link, and the clutch shaft 22 on the retractable tube driving device 21 is driven by the rear driving rod 81. The utility model also assists in adjusting the position of the ground support seat 55 by extending the extendable extension rod 5 to achieve stable support of the towing frame 1.

[0038] The utility model adopts mechanical driving, and can effectively realize the parking linkage of the trailer irrigation vehicle. This structure eliminates the complexity of multi-person operation and the instability of the electric control system, and is an ideal parking linkage structure of the trailer irrigation vehicle.
