[0029] Example:

[0030] Reference Figure 1-Figure 7 The utility model embodiment provides a frame for an electric tractor, including a frame body 1, and also includes: two connecting arms 2, both of which are installed on the frame body 1, wherein the frame body 1 is provided with an adjustment part, and the adjustment part is used to drive the two connecting arms 2 to move toward or away from each other; two hooks 3 with open surfaces are provided, which are fixedly connected to the two connecting arms 2 respectively, wherein the two hooks 3 are both installed with arc blocks 4, and the arc surfaces of the two arc blocks 4 are arranged facing each other, and the hooks 3 are provided with elastic members, and the arc blocks 4 are pressed against the outer wall of the open part of the hook 3 by the elastic force of the elastic members.

[0031] Specifically, when in use, through the setting of the adjustment part, the two hooks 3 can be driven to move towards each other, so that the hooks 3 are sleeved on the mounting arms of the agricultural machinery, which can facilitate the rapid installation of the agricultural machinery, thereby improving work efficiency, and through the coordinated use of the elastic member and the arc block 4, the mounting arms of the agricultural machinery can be limited, thereby improving the installation stability of the agricultural machinery and the electric tractor frame.

[0032] The adjustment part includes: a shell 21, which is fixedly connected to the frame body 1, wherein a motor 22 is fixedly installed on the outer wall of the shell 21, a double-headed screw 23 is rotatably connected inside the shell 21, and the threads on both sides of the outer wall of the double-headed screw 23 are designed in opposite directions. Two moving blocks 24 are slidably installed on the shell 21, and the two moving blocks 24 are respectively threadedly connected to both sides of the outer wall of the double-headed screw 23, and the connecting arm 2 is installed on the moving block 24.

[0033] Specifically, when in use, by starting the motor 22, the output end of the motor 22 drives the double-headed screw 23 to rotate, and under the action of the opposite threads, the moving block 24 drives the two connecting arms 2 to move towards each other, and drives the hook 3 and the arc block 4 to move together, so that the installation arm with a slot on the agricultural machinery passes through the open part of the hook 3 and is sleeved on the hook 3, so that the agricultural machinery can be installed and connected to the frame.

[0034] The elastic member includes:

[0035] The pull rod 42 is slidably connected to the hook 3, wherein a through slot 41 is provided on the hook 3, and the arc block 4 is slidably connected in the through slot 41. One end of the pull rod 42 is fixedly connected to the arc block 4, and a spring 43 is sleeved on the pull rod 42. The two ends of the spring 43 are respectively fixedly connected to the surface of the arc block 4 and the inner wall of the through slot 41.

[0036] Specifically, when in use, during the process of installation and sleeve connection between the hook 3 and the mounting arm of the agricultural machinery, the mounting arm on the agricultural machinery will squeeze the arc surface of the arc block 4, causing the arc block 4 to slide into the through groove 41 and push the pull rod 42 to move, while compressing the spring 43. When the mounting arm on the agricultural machinery passes through the opening of the hook 3, under the elastic force of the spring 43, the arc block 4 slides out of the through groove 41 and blocks the opening of the hook 3, which can limit the mounting arm of the agricultural machinery and improve the installation stability of the agricultural machinery and the electric tractor frame.

[0037] One end of the pull rod 42 away from the arc block 4 is fixedly connected with a knob 8, and the shape of the knob 8 is hexagonal.

[0038] Specifically, by setting the knob 8, it is convenient for workers to apply force to pull the pull rod 42 and the arc block 4, so as to facilitate the removal of the agricultural machinery from the frame, and the hexagonal design can play an anti-slip role.

[0039] A guide tube 5 is arranged between the two connecting arms 2, and T-slots 6 are slidably installed on both sides of the guide tube 5, and one end of the T-slot 6 away from the guide tube 5 is fixedly connected to the connecting arm 2; one end of the connecting arm 2 is rotatably connected to the moving block 24, and a hydraulic rod 52 is rotatably connected to the frame body 1, and the output end of the hydraulic rod 52 is rotatably connected to the top of the guide tube 5 through the connecting block.

[0040] Specifically, when in use, by starting the hydraulic rod 52, the output end of the hydraulic rod 52 contracts or extends, and drives the guide tube 5, the guide rod 51 and the connecting arm 2 to deflect upward or downward, so that the position of the hook 3 can be adjusted, so that the frame can be suitable for the installation of agricultural machinery of different models and sizes, which is beneficial to the use of electric tractors.

[0041] A T-shaped groove 6 is formed on the inner wall of the housing 21 , and a T-shaped block 7 is fixedly connected to the surface of the moving block 24 . The T-shaped block 7 is laterally slidably connected in the T-shaped groove 6 .

[0042] Specifically, by providing the T-shaped groove 6 and the T-shaped block 7, the moving block 24 can be guided, thereby improving its use stability.

[0043] The motor 22 is covered with a protective shell 9 , which is detachably mounted on the outer wall of the housing 21 .

[0044] Specifically, by providing the protective shell 9, the motor 22 can be shielded and protected to prevent dirt and impurities from adhering to the motor 22 and thus affecting its service life.

[0045] One end of the T-shaped slot 6 away from the connecting arm 2 is fixedly connected to a limiting block 10 , and the limiting block 10 is slidably connected to the inside of the guide tube 5 .

[0046] Specifically, by providing the limiting block 10 , the guide rod 51 can be limited to prevent it from being separated from the guide tube 5 .

[0047] Working principle: During the use of the electric tractor frame, when the required agricultural implements are installed and connected, the motor 22 is started, and the output end of the motor 22 drives the double-headed screw 23 to rotate. Under the action of the opposite threads, the moving block 24 drives the two connecting arms 2 to move towards each other, and drives the hook 3 and the arc block 4 to move together, so that the installation arm with a slot on the agricultural implement passes through the open part of the hook 3 and is sleeved on the hook 3, thereby completing the installation and connection of the agricultural implement and the frame;

[0048] At the same time, during the process of hooking the hook 3 and the mounting arm, the mounting arm on the agricultural machinery will squeeze the arc surface of the arc block 4, so that the arc block 4 slides into the through groove 41 and pushes the pull rod 42 to move, and at the same time compresses the spring 43. When the mounting arm on the agricultural machinery passes through the opening of the hook 3, under the elastic force of the spring 43, the arc block 4 slides out of the through groove 41 and blocks the opening of the hook 3. The frame of the electric tractor drives the two hooks 3 to move towards each other through the motor 22, so that the hook 3 is mounted on the mounting arm of the agricultural machinery, which can facilitate the rapid installation of the agricultural machinery, thereby improving work efficiency.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
