[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an adjustable counterweight mechanism for a tractor, including a fixing component 1. A support plate 2 for support is fixedly installed on one side of the fixing component 1. A fixing plate 21 is fixedly connected to one side of the support plate 2. Two screws 22 are fixedly installed on the front and rear sides of the fixing plate 21 respectively. Multiple counterweight blocks 3 are slidably connected to one side of the support plate 2 on both the front and rear sides of the fixing plate 21. The multiple screws 22 pass through the multiple counterweight blocks 3 respectively. A disassembly and assembly component 4 is provided on the outside of every two screws 22. The two disassembly and assembly components 4 are located on the front and rear sides of the multiple counterweight blocks 3 respectively and support and fix the multiple counterweight blocks 3. Two movable plates 43 are slidably installed inside each disassembly and assembly component 4. When in use, the fixing component 1 is fixed in a suitable position on the front of the tractor. By moving the two movable plates 43 together, the disassembly and assembly component 4 can be moved outward and separated from the screw 22, making it easy to slide the counterweight 3 along the support plate 2 and to disassemble and install it. By disassembling and installing different numbers of counterweights 3, the weight of the counterweight can be adjusted. By fitting the disassembly and assembly component 4 on the outside of the two screws 22 and making the disassembly and assembly component 4 fit against the counterweight 3, and then pushing the two movable plates 43 to separate and move, the disassembly and assembly component 4 and the screw 22 can be fixed. The disassembly and assembly component 4 can be used to support and fix the counterweight 3, and the counterweight 3 can be disassembled and installed conveniently and quickly.

[0017] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the fixing component 1 includes a steel frame 11, with two fixing pins 12 penetrating the bottom of the steel frame 11. Both fixing pins 12 are slidably connected to the steel frame 11. The support plate 2 is fixedly connected to the steel frame 11 via a connecting frame 13. By pulling the fixing pins 12 to one side to separate them from the steel frame 11, and then snapping the steel frame 11 into a suitable position on the tractor front, the fixing pins 12 are inserted into the inside of the steel frame 11 to reset it. This fixes the steel frame 11 to the front of the tractor front. The connecting frame 13 provides support and fixation between the support plate 2 and the steel frame 11.

[0018] As one implementation method in this embodiment, please refer to Figure 1 - Figure 4 As shown, each counterweight 3 has a slot 31 on one side, and each counterweight 3 is slidably connected to the support plate 2 through the slot 31. The slot 31 allows the counterweight 3 to slide back and forth along the support plate 2, making it easy to disassemble and install the counterweight 3.

[0019] As one implementation method in this embodiment, please refer to Figure 1 - Figure 4 As shown, each counterweight 3 has two positioning holes 32 inside. Each pair of screws 22 passes through the two positioning holes 32. A handle groove 33 is provided on the inner side of the counterweight 3 above the screws 22. The positioning holes 32 allow the screws 22 to pass through the counterweight 3 and provide positioning support for the counterweight 3. The handle groove 33 makes it easy for personnel to manually lift the counterweight 3.

[0020] As one implementation method in this embodiment, please refer to Figure 1 - Figure 5 As shown, the assembly / disassembly component 4 includes a fixed cylinder 41 and a movable plate 43 slidably connected inside the fixed cylinder 41. Each fixed cylinder 41 has two fixing holes 42 on its front and rear sides, and each pair of screws 22 passes through the fixed cylinder 41 through the fixing holes 42. By having the two screws 22 pass through the fixed cylinder 41 through the multiple fixing holes 42, the fixed cylinder 41 can be easily fitted onto the outside of the two screws 22.

[0021] As one implementation method in this embodiment, please refer to Figure 1 - Figure 5 As shown, a pressure plate 46 is fixedly installed on one side of each movable plate 43. Every two pressure plates 46 extend outward from the outer side of a disassembly and assembly component 4 and are slidably connected to the disassembly and assembly component 4. A support seat 44 that meshes with two screws 22 is fixedly installed on the outer side of each two movable plates 43. By pressing the two pressure plates 46, the two pressure plates 46 are moved together, which can drive the two movable plates 43 to move together synchronously.

[0022] As one implementation method in this embodiment, please refer to Figure 1 - Figure 5 As shown, each assembly / disassembly component 4 has a thrust spring 45 inside. Each thrust spring 45 is located inside the two movable plates 43 and is fixedly connected to the two movable plates 43. When the two movable plates 43 move together, the thrust spring 45 can be compressed. Using the thrust of the thrust spring 45, the two movable plates 43 can be pushed to move apart.

[0023] Working principle: By removing the fixing pin 12, the steel frame 11 is clamped onto the tractor head. Then, the fixing pin 12 is inserted into the inside of the steel frame 11 to reset it, which can fix the steel frame 11 to the tractor. The connecting frame 13 can support and fix the steel frame 11 to the support plate 2. By pressing the two pressure plates 46 to move them together, the two movable plates 43 can be moved together synchronously, causing the two movable plates 43 to separate the two support seats 44 from the screw 22. The fixed cylinder 41 can be moved outward and separated from the screw 22. By sliding the counterweight 3 back and forth along the support plate 2, the counterweight 3 can be easily disassembled and installed. By disassembling and installing different numbers of counterweight 3, the weight of the tractor counterweight can be adjusted according to the number of counterweight 3. By fitting the fixing cylinder 41 onto the outside of the two screws 22, the screws 22 pass through the fixing hole 42 through the fixing cylinder 41. Then, the fixing cylinder 41 is pushed to move and fit against the counterweight 3. By loosening the pressure plate 46, the two movable plates 43 can be pushed to move separately using the thrust of the thrust spring 45. This simultaneously drives the support base 44 to move outward, and the support base 44 engages with the screws 22, which can support and fix the disassembly assembly 4 and the screws 22. At the same time, the disassembly assembly 4 supports and fixes multiple counterweights 3, making it easier to disassemble and install the counterweights 3. Alternatively, a nut can be used instead of the fixing cylinder 41 and screwed onto the outside of the screws 22 to support and fix the counterweights 3, avoiding the situation where it is difficult to fix the counterweights 3 if the disassembly assembly 4 is damaged or lost.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
