[0002] The tractor is equipped with connecting brackets at the front and rear ends of its body to match different working machines and implement rotary tillage, plowing, transplanting, grader, bucket or loading operations. As market users have more and more requirements for the diversity of supporting tools for front loaders, traditional quick-change connecting brackets need to adapt to different working machines and implements. For example, while meeting the installation requirements of buckets, they also need to meet the installation requirements of forks and square forks. However, due to the differences in the bracket structure and installation limit surfaces of different agricultural machinery, the adaptability of the connecting bracket is poor, and it cannot be directly connected by the driver driving the tractor.

[0003] In the prior art, it is therefore necessary to provide a front loading rack to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to provide a front loading frame and a tractor.

[0038] See attached Figures 1 to 5 The present embodiment provides a front loading frame 1, which is arranged at the front end of a tractor 3 and mounted with an operating tool 2, wherein the operating tool 2 may be, but is not limited to, a bucket, a grass fork, a bulldozer, a digging bucket, and a grab bucket. However, for those skilled in the art, the front loading frame 1 may also be applied to the fields of trucks, engineering machinery, etc., which are not listed here one by one. The connecting bracket includes a mounting side plate 11, a first crossbeam 12, a locking assembly, and an adjustable support member 18.

[0039] The mounting side plates 11 are respectively arranged on both sides of the front end of the tractor 3, and the mounting side plates 11 on both sides are connected to form a whole through the first cross beam 12, the second cross beam 14 and the connecting rod 13, wherein the second cross beam 14 is located in the middle of the mounting side plate 11; the connecting rod 13 is located at the lower part of the mounting side plate 11, and the second cross beam 14 is located in the middle area of ​​the mounting side plate, which plays the role of a reinforcing rib and improves the stability of the connecting bracket. In addition, a connecting hole 112 is also provided on the mounting side plate 11, and the front loading frame 1 can be fixedly connected to the tractor 3 by bolt fixing to form a whole; the first crossbeam 12 is installed on the upper part of the mounting side plate 11, so that the hook 21 on the working agricultural implement can be mounted on the first crossbeam 12; the locking assembly includes a mounting hole 111 provided on the mounting side plate 11, and a pin shaft can pass through the mounting hole 111 and the locking hole 22 on the working machine 2; the adjustable support member 18 is installed on the mounting side plate 11, specifically, the adjustable support member includes: a mounting seat 181 and a limiting bolt 182, the mounting seat 181 is installed on the mounting side plate 11; the limiting bolt 182 is installed on the mounting side plate 11, and can be radially adjusted along the mounting hole 111 until the locking hole 22 is concentric with the mounting hole 111.

[0040] During the assembly of the agricultural machinery, the hook 21 of the working tool 2 is mounted on the first crossbeam 12. Under the action of gravity, the connecting end face of the working tool 2 abuts against the connecting end face of the connecting bracket. Since different working tools 2 have different installation limit surfaces, the locking hole 22 of the working tool 2 cannot be directly connected with the locking component of the connecting bracket. In this embodiment, the utility model adds an adjustable support member 18 at the mounting point under the front-loading quick-change connecting bracket. When the work tool 2 is first assembled, the user only needs to easily adjust the length of the adjustable support member 18 so that the locking hole 22 and the guide member 16 of the work tool 2 are adjusted to be concentric, and the initial locking and installation of the work tool 2 can be achieved; when the user replaces the work tool 2 again, the work tool 2 is lifted and the work tool 2 is contacted with the adjustable support member 18 by its own gravity to achieve positioning and complete automatic alignment. The entire process of alignment between the locking hole 22 of the work tool 2 and the mounting hole 111 does not require manual step-by-step adjustment, which solves the problem of difficulty in switching between the front-loading pitchfork and the bucket. The operation of mounting the work tool 2 is simpler and more convenient, more time-saving, convenient, safer and more efficient, and the operating efficiency is significantly improved under the condition that the usage function remains unchanged.

[0041] It is understandable that a telescopic module 15 is provided between the two pins 17 to drive the two pins 17 to move toward or away from each other. For those skilled in the art, there are many options for the telescopic module 15, which can be an automated driving device such as a cylinder, an oil cylinder, a motor linear module, or a manual connecting rod 153 structure. In this embodiment, an exemplary structure is given, in which the telescopic module 15 is a scissor-type connecting rod 153 structure, and the scissor-type connecting rod 153 structure includes: a driving rod and two connecting rods 153; the driving rod includes an operating rod 151 whose central region is rotatably mounted on the connecting rod 13, and a handle 152 integrally formed at one end of the operating rod 151 and extending outward; one end of the connecting rod 153 is respectively connected to the two ends of the operating rod 151 symmetrically distributed with the rotation point of the operating rod 151 as the midpoint, and the other ends of the two connecting rods 153 are respectively connected to two pins 17. The operating rod 151 is manually rotated along the rotation point, thereby driving the two connecting rods 153 to rotate along the tangent of the operating rod 151, thereby driving the two pin shafts 17 to move toward or away from each other.

[0042] In order to ensure the stability of the locking of the locking assembly, on the one hand, the mounting side plate 11 is also provided with a guide 16 which is arranged concentrically with the mounting hole 111. The guide 16 is a pin barrel fixedly mounted on the mounting side plate 11, which can ensure the stability and accuracy of the pin shaft 17 when it is inserted into the mounting hole 111 and / or the locking hole 22. On the other hand, a through hole 171 is provided on the pin shaft 17, which cooperates with the latch to realize the locking and unlocking of the locking assembly. The safety of the working tool 2 during use is ensured to prevent the pin shaft 17 from moving, resulting in abnormal unlocking of the locking assembly and forming a safety hazard.

[0043] It will be apparent to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention covers modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
