Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural tool production and manufacturing, in particular to a fixing device for an agricultural tractor head. Background Art
[0002] An agricultural tractor is a type of agricultural machinery used for plowing, harrowing, soil preparation, tillage, sowing, harvesting, and transporting in the fields. Tractors are further subdivided into wheeled tractors, crawler tractors, disc tractors, walking tractors, and boat tractors based on their specific usage scenarios and functions. Wheeled tractors and walking tractors are the most commonly used tillage machines for individual farmers. While they offer significant auxiliary agricultural functions, they both utilize a separate drive and load-bearing assembly design. Therefore, during maintenance, the engine head, which serves as the tractor's primary power source, needs to be disassembled and repaired separately. Once disassembled, the engine head is prone to tilting forward and flipping, as most of the power unit is located at the front end. This greatly increases the difficulty of maintenance and can pose a threat to maintenance personnel during the flipping process. Therefore, the existing technology urgently needs a technical solution to address the aforementioned issues. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0019] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.
[0020] Example
[0021] like Figures 1 to 4 As shown, the utility model provides a fixing device for the head of an agricultural tractor, including a base plate 1, a limiting arc groove 11 is provided on the base plate 1, and a head component 2 is installed in the limiting arc groove 11, a traction component 3 for fixing the head component 2 is fixedly installed on the base plate 1, and a locking component 4 for locking the traction component 3 is fixedly installed on one side of the traction component 3.
[0022] As a further illustration of this embodiment, in the prior art, wheeled tractors and walking tractors are the most commonly used tillage machines for individual farmers. Although they have a strong auxiliary effect in agricultural work, they both adopt a separate drive and load-bearing assembly connection design. Therefore, during maintenance, the head, which is the main power source of the tractor, needs to be separately disassembled for repair. Once the head is disassembled, most of the power devices are located at the front end of the head, making it prone to tilting forward and flipping, which greatly increases the difficulty of maintenance and may also pose a threat to maintenance personnel during the flipping process. In this embodiment, the tractor is moved onto the base plate 1, and the bottom of the tractor head is forced into the limiting arc groove 11 to restrain the tractor head, preventing it from moving further. The tractor head is then fixed by the traction assembly 3 to prevent uncontrolled flipping of the mechanical components during the disassembly process. At the same time, the traction assembly 3 is limited by the locking assembly, ensuring the stability of the traction assembly 3, thereby allowing the flipping of the head component 2 to be adjusted, thereby making the maintenance of the head component 2 more convenient and safe.
[0023] Furthermore, the nose component 2 includes a front wheel group 21 that penetrates into the limiting arc groove 11, and a connecting long plate 22 is fixedly connected to the front wheel group 21, and an engine 23 is fixedly installed on the connecting long plate 22, and a cover 24 is fixedly installed on the top of the engine 23.
[0024] Furthermore, the traction assembly 3 includes a connecting column 31 installed at the end of the connecting long plate 22, and a connecting ring 32 is fixedly installed at the bottom of the connecting column 31, a bracket 33 is fixedly installed on the base plate 1, a roller 34 is rotatably connected inside the bracket 33, a rope is wrapped around the roller 34, and one end of the rope is fixedly connected to the connecting ring 32, and a crank 35 is fixedly connected to one side of the roller 34.
[0025] As a further explanation of this embodiment, in this embodiment, the rope is fixedly connected to the bottom of the connecting ring 32 by installing a connecting column 31 in the connecting long plate 22, and the front wheel group 21 in the head component 2 is deeply trapped in the limiting arc groove 11 and cannot move. Therefore, when the head component 2 flips around the circumferential direction of the front wheel group 21, the connecting long plate 22 drives the connecting column 31 to move upward, and one end of the rope is fixedly connected to the connecting ring 32, and the other end is wrapped around the roller 34. By controlling the crank 35, the overall force of the head component 2 can be balanced, and shaking the crank 35 can adjust the number of turns of the rope wrapped around the roller 34 to control the minimum distance between the connecting long plate 22 and the bottom plate 1, thereby controlling the flipping angle of the head component 2.
[0026] Furthermore, the locking assembly 4 includes a chuck 41 fixedly mounted on the side wall of the bracket 33, a plurality of limiting holes 42 are provided on the chuck 41, a receiving ring 43 is sleeved on the crank 35, the receiving ring 43 and the crank 35 are slidably connected to the same adjusting rod 44, an annular support plate 45 is fixedly mounted on the adjusting rod 44, a spring 46 is sleeved on the adjusting rod 44, and the two ends of the spring 46 are respectively pressed against the side wall of the annular support plate 45 and the outer wall of the receiving ring 43.
[0027] As a further explanation of this embodiment, although the crank 35 in this embodiment has the effect of controlling the flipping angle of the head component 2, the overall weight of the head component 2 is relatively large. Even after the force of multiple levels of transmission, it will be very manpower-consuming to control the rotation of the crank 35 by manpower. Therefore, an adjustment rod 44 is inserted into the crank 35, and the adjustment rod 44 is pressed tightly and extended into the limit hole 42 by the elastic force of the spring 46 to limit the rotation of the crank 35, thereby saving manpower and enhancing the stability of the traction component 3.
[0028] Furthermore, a handle 47 is fixedly connected to one end of the adjusting rod 44 close to the receiving ring 43 , and a semi-arc frame 48 for placing the handle 47 is fixedly connected to one side wall of the receiving ring 43 .
[0029] As a further explanation of this embodiment, in this embodiment, if it is necessary to rotate the crank 35, the adjusting rod 44 is pulled out from the limiting hole 42 through the handle 47, and the adjusting rod 44 is rotated so that the handle 47 overlaps the side wall of the semi-arc frame 48, and the adjusting rod 44 is elastically pushed into the limiting hole 42, thereby achieving the effect of releasing the crank 35. After using the handle 47 to adjust the number of turns of the rope, the handle 47 can be rotated again to make the handle 47 fit the arc of the semi-arc frame 48, and the adjusting rod 44 can be pushed into the corresponding limiting hole 42 by the elastic force of the spring 46.
[0030] Furthermore, a buffer pad 5 for buffering is fixedly mounted on the bottom plate 1 .
[0031] As a further explanation of this embodiment, in this embodiment, when the head component 2 is rotated to the extreme angle, the connecting long plate 22 may collide with the base plate 1. In order to avoid the crank 35 being adjusted too quickly, which may cause a direct collision between the head component 2 and the base plate 1 and cause damage, a buffer pad 5 is laid under the head component 2 to alleviate the impact force generated when the head component 2 flips too quickly.
