Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4As shown, an adjustment device for a paddy field pulverizer includes a paddy field pulverizer 1 and an adjustment assembly 2. The adjustment assembly 2 includes a large back square tube 26, a balance shaft 27, a first welding plate 21, a second welding plate 22, a third welding plate 23, a fourth welding plate 24, and a telescopic component 25. One end of the telescopic component 25 is installed on the paddy field pulverizer 1, and the other end is installed on the large back square tube 26. The balance shaft 27 passes through the first welding plate 21, the second welding plate 22, the third welding plate 23, and the fourth welding plate 24. The first welding plate 21 and the second welding plate 22 rotate around the balance shaft 27.

[0020] Preferably, a set of lifting lugs a3 are provided at the bottom ends of the first welding plate 21 and the second welding plate 22; and a set of lifting lugs b4 are provided at the bottom ends of the third welding plate 23 and the fourth welding plate 24.

[0021] Preferably, a positioning nut 10 is provided on the balance shaft 27.

[0022] Preferably, the second bushing 5 is embedded in the lug a3, the first bushing 6 is embedded in the lug b4, and the balance shaft 27 passes through the first bushing 6 and the second bushing 5 in sequence, and is fixed by the washer 7 and the positioning nut 10.

[0023] Preferably, the first welding plate 21 and the second welding plate 22 are installed on the main beam of the paddy field pulverizer.

[0024] Preferably, the telescopic component 25 is hydraulic oil.

[0025] Preferably, the large back square tube 26 is provided with suspension points 8 at both ends, and positioning pins 9 are provided on both sides of the suspension points 8, wherein the positioning pins 9 are movable. Example

[0026] The first welding plate 21 and the second welding plate 22 are welded to the main beam of the paddy field pulverizer. The balance shaft 23 passes through the first bushing 6 and the second bushing 5. The balance shaft 27 is the rotation point. Applying external force can make the first welding plate 21 and the second welding plate 22 rotate around the balance shaft 27.

[0027] The large back square tube 26 is not fixedly installed on the main beam of the paddy field pulverizer. It is only connected to the first welding plate 21 and the second welding plate 22 through the balance shaft 23. The connection between the two is a movable connection. Specifically, the large back square tube 26 is connected to the tractor through the suspension point 8, that is, the large back square tube 26 is a fixed end, and the first welding plate 21 and the second welding plate 22 can rotate around the balance shaft 27.

[0028] The telescopic component 25 uses a hydraulic cylinder. One end of the hydraulic cylinder is fixedly connected to the suspension frame of the paddy field threshing machine, which is installed on the main beam of the paddy field threshing machine. The other end is fixedly installed on the large back square tube 26. The large back square tube 26 is connected to the tractor through the suspension points 8 on both sides (i.e., the large back square tube 26 is essentially stationary). When the hydraulic cylinder extends or retracts, it applies an external force to the main beam. The first welded plate 21 and the second welded plate 22 at the lower end of the main beam rotate naturally around the balance shaft 27. This allows the left and right height adjustment of the paddy field threshing machine to achieve balance. Example

[0029] The large back square tube 26 has suspension points 8 on both sides, and each suspension point 8 has an extension plate on its side. The extension plate has a positioning pin 9. The positioning pin 9 can be inserted into the main beam of the paddy field pulverizer to lock the angle of the main beam, which is convenient for transporting the paddy field pulverizer when it is not in operation. When it is used in the paddy field, the positioning pin 9 needs to be removed to adjust the angle.

[0030] The above description is only a specific embodiment of this utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of the utility model.
