Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an agricultural machinery towing device. Background Technology

[0002] When a tractor drives agricultural implements for movement, a towing device is needed to connect the two. Patent publication number CN219373039U, publication date July 21, 2023, entitled "A Towing Device for Agricultural Implements," describes a towing device where a first connecting component and a second connecting component are connected by a pin during towing. Because the pin is used, vibrations during movement can cause the pin to move, leading to its disengagement and separation between the towed agricultural implement and the tractor. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that vibration occurs during movement, causing the pin to come off, resulting in the separation of the towed agricultural implement from the tractor, and thus a new agricultural machinery towing device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an agricultural machinery towing device, including a first fixed base, on which two first connecting seats are fixedly connected, and a second connecting seat is connected to the second fixed base via a connecting mechanism. Both the second and first connecting seats have connecting holes, and a pin is provided in the connecting hole. A connecting cap is fixedly connected to the upper end of the pin. A through cavity is provided on the pin and the connecting cap, and a limiting cylinder is inserted through the through cavity. The limiting cylinder moves via a moving mechanism.

[0006] Preferably, both the first fixing seat and the second fixing seat are provided with fixing holes.

[0007] Preferably, the moving mechanism includes a crossbar, on which the limiting cylinder is sleeved, and a moving plate is fixedly connected to the limiting cylinder. A second spring is fixedly connected between the moving plate and the inner wall of the cavity.

[0008] Preferably, the second spring is a stainless steel spring.

[0009] Preferably, the upper end of the movable plate extends out of the cavity.

[0010] Preferably, the connecting mechanism includes a connecting ridge, which is fixedly connected to the second fixed seat. The second connecting seat has a through groove, through which the connecting ridge passes. Both the upper and lower surfaces of the second connecting seat are abutted by a first spring, which is fixedly connected to the second fixed seat.

[0011] Preferably, the first spring is a compression spring.

[0012] The agricultural machinery towing device proposed in this utility model has the following advantages: the connecting cap and the limiting cylinder limit the pin, so that the pin is always placed in the fixing hole, preventing the pin from coming off when the tractor moves, avoiding separation between the agricultural machinery and the tractor, and ensuring the connection effect of the towing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3 An agricultural machinery towing device includes a first fixed seat 1, on which two first connecting seats 8 are fixedly connected. The first fixed seat 1 is fixedly connected to the tractor by bolts, and the second fixed seat 4 is fixedly connected to the agricultural machinery implement by bolts.

[0019] The second fixed seat 4 is connected to the second connecting seat 9 via a connecting mechanism. Both the first fixed seat 1 and the second fixed seat 4 have fixed holes, and both the second connecting seat 9 and the first connecting seat 8 have connecting holes. A pin 6 is installed in the connecting hole, and a connecting cap 2 is fixedly connected to the upper end of the pin 6. A through cavity 10 is opened on the pin 6 and the connecting cap 2. A limiting cylinder 7 is installed through the through cavity 10. The limiting cylinder 7 moves through the moving mechanism. The connecting cap 2 and the limiting cylinder 7 limit the pin 6, so that the pin 6 is always placed in the fixed hole, preventing the pin 6 from coming off when the tractor moves. This avoids the separation between the agricultural implement and the tractor and ensures the connection effect of the trailer.

[0020] The moving mechanism includes a crossbar 13, on which a limiting cylinder 7 is sleeved. A moving plate 12 is fixedly connected to the limiting cylinder 7. The upper end of the moving plate 12 extends into a cavity 10. A second spring 11 is fixedly connected between the moving plate 12 and the inner wall of the cavity 10. The second spring 11 is a stainless steel spring. By moving the moving plate 12, the limiting cylinder 7 is moved and inserted into the cavity 10 so that the pin 6 can be removed. After use, the device can be separated from the tractor.

[0021] Example 2: Refer to Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, the connecting mechanism includes a connecting ridge 3, which is fixedly connected to the second fixed seat 4. The second connecting seat 9 has a through groove, through which the connecting ridge 3 passes. The upper and lower surfaces of the second connecting seat 9 are abutted by a first spring 5, which is fixedly connected to the second fixed seat 4. The first spring 5 is a compression spring. When traveling on a bumpy road, the height between the tractor and the agricultural implement changes continuously, which will compress the first spring 5. The first spring 5 undergoes elastic deformation, which plays a buffering role and facilitates pulling on bumpy roads.

[0022] By using the connecting cap 2 and the limiting cylinder 7 to limit the pin 6, the pin 6 is always placed in the fixed hole. When separation is required, the moving plate 12 is moved to drive the limiting cylinder 7 to move into the through cavity 10 so that the pin 6 can be removed, the first connecting seat 8 and the second connecting seat 9 can be separated, and the device can be separated from the tractor.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
