Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-6 This embodiment provides the following technical solution: an agricultural machinery quick-attachment device, including a hanging beam 1 and a quick-attachment shaft 2. The hanging beam 1 includes a hanging beam 11 and a hanging frame 12. Multiple hanging frames 12 are fixedly connected to the hanging beam 11 along its axial direction. In some embodiments, the hanging beam 11 is fixed to the matching agricultural implement. The hanging frame 12 includes a clamping plate and a connecting plate 12a. The left and right sides of the clamping plate are fixedly connected to the connecting plate 12a, and the connecting plate 12a is fixedly connected to the hanging beam 11.

[0027] In some embodiments, the card plate includes a limiting part 12b and a guide part 12c. The limiting part 12b has a U-shaped structure, and the guide part 12c is fixedly connected to both ends of the limiting part 12b. The other end of the guide part 12c is bent outward. Through the limiting part 12b and the guide part 12c, the quick-release shaft 2 can be quickly inserted into the card plate.

[0028] The guide portion 12c of the card plate is provided with a limiting hole 12d for the pin to pass through. After the quick-release shaft 2 is assembled onto the bracket 12, the pin is simply inserted into the limiting hole 12d and the cotter pin is inserted into the other end of the pin to limit the pin, thereby assembling the quick-release shaft 2 onto the hanging beam 11.

[0029] The hanger 12 is provided with a first hanging groove 13 with the opening facing downward, which is used to quickly assemble the quick-mount shaft 2 onto the hanger 12. In some embodiments, the hanger 12 is provided with two, and the first hanging groove 13 is a U-shaped structure. The quick-mount shaft 2 is quickly assembled by inserting it into the first hanging groove 13 on the hanger 12.

[0030] The connecting plate 12a is provided with guide slopes 14 on both the front and rear sides at the bottom of the first hanging groove 13. The guide slopes 14 can better enable the connecting plate 12a to cooperate with the card plate, making it easier for the quick-hanging shaft 2 to move upward and be inserted into the first hanging groove 13.

[0031] The quick-release shaft 2 is detachably connected to the hanging beam 1. The quick-release shaft 2 includes a shaft body 21, a hanging lug 22, and a pin 24. Both ends of the shaft body 21 are fixedly connected to the hanging lug 22. In some embodiments, two hangers 12 are located between the hanging lugs 22 at both ends, and the outer side of the hanger 12 is fitted with the corresponding hanging lug 22. With the cooperation of the hanging beam 11 and the hanging lug 22, the two ends of the shaft body 21 can be limited to prevent the shaft body 21 from sliding freely on the hanger 12.

[0032] The ear 22 is provided with a second hanging groove 23 with its opening facing upward, for aligning with the hanging ring on the matching agricultural implement; the ear 22 is provided with a shaft hole 25 for the pin 24 to pass through, for limiting the hanging ring on the matching agricultural implement. In some embodiments, the shaft hole 25 on the shaft body 21 and the shaft hole 25 on the ear 22 are concentrically arranged. When the shaft holes 25 on the shaft body 21 and the ear 22 correspond to the hanging arm on the matching agricultural machinery, one end of the pin 24 can pass through the ear 22 to limit the hanging arm on the agricultural machinery to be positioned inside the second hanging groove.

[0033] In some embodiments, workers can quickly assemble the quick-connect shaft 2 onto the agricultural machinery and then quickly assemble the connecting beam 1 on the matching implement onto the quick-connect shaft 2, thereby completing the quick attachment of the matching implement to the agricultural machinery, replacing the traditional attachment method. This method is more efficient, simpler to operate, and reduces the driving requirements for the driver.

[0034] A positioning element 26 is fixedly connected to the side of the lug 22 away from the shaft 21. The positioning elements 26 on the two lugs 22 cooperate with each other to form the positioning structure of the pin 24. The positioning element 26 includes two positioning ears 26a, which are symmetrically distributed on the lug 22 with the shaft hole 25 as the center. The positioning ears 26a are provided with positioning holes 26b for the pin to pass through. Through the positioning ears 26a and positioning holes 26b, after the pin 24 is inserted into the lug 22, the outer end of the pin 24 can be limited, so that the pin 24 is fixedly installed on the lug 22.

[0035] The working principle of this utility model is as follows: When in use, the quick-release shaft 2 needs to be installed on the agricultural machinery equipment first. When quick-release, the hanging arm on the agricultural machinery equipment needs to be inserted into the second hanging groove 23. Then, the pin 24 is inserted into the shaft hole 25 and the hole groove on the hanging arm to limit the hanging arm in the second hanging groove 23. Then, the pin 24 is inserted into the positioning hole to limit the outer end of the pin 24. Similarly, the hanging arm on another agricultural machinery equipment is installed on another hanging ear 22, thereby completing the purpose of quickly installing the quick-release shaft 2 on the agricultural machinery equipment.

[0036] Then drive the agricultural machinery to move it toward the matching implement until the shaft 21 is aligned with the first mounting slot 13. Then start the agricultural machinery to make the hanging arm drive the quick-hanging shaft 2 upward, so that the shaft 21 is locked inside the first mounting slot 13. At the same time, insert the pin into the limiting hole 12d, so that the hanging beam 11 can be quickly assembled onto the quick-hanging shaft 2, thereby completing the purpose of assembling the matching implement onto the agricultural machinery.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
