Description

Technical Field

[0001] The utility model relates to a disc plough, in particular to a disc plough tail wheel bent shaft capable of realizing tail wheel angle adjustment. Background Art

[0002] A disc plow is a tillage machine with a disc plow body as its working part. The disc is usually a part of a hollow sphere with a cutting edge ground on its edge to facilitate cutting grass and entering the soil. The disc is supported solely on the bearing of the plow column. The disc surface forms an angle with the forward direction and the plumb direction respectively, which are called the deflection angle α and the inclination angle β. Generally, there are 3 to 6 disc plow bodies on a standard disc plow. When working, the unit moves forward, the disc rolls and cuts into the soil, and the soil rises along the concave surface of the disc. At the same time, the scraper board cooperates to make the soil flipped and broken.

[0003] In the prior art, the lateral force generated by the disc plow during tillage is mainly balanced by the tail wheel. The balancing ability of the lateral force of the tail wheel directly affects the tillage performance, the stability of the unit and the straight-line driving performance. The tail wheel is subjected to different forces under different working conditions, and different soil properties also have different supporting effects on the tail wheel. Therefore, it is usually necessary to adjust the inclination and deflection of the tail wheel to improve its lateral force balancing ability. The existing tail wheel shaft is straight. When the tail wheel shaft rotates, although the tail wheel rotates with it, the inclination and deflection will not change, and the angle of the tail wheel cannot be adjusted and fixed, resulting in poor use effect. Now, there is an urgent need for a disc plow tail wheel bent shaft that can realize tail wheel angle adjustment to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a disc plow tail wheel bending axis capable of adjusting the tail wheel angle, so as to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure, can adjust and fix the tail wheel angle, and has a good use effect.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a disc plow tail wheel bending axis capable of adjusting the tail wheel angle, comprising:

[0006] A tail wheel shaft is provided on a tail wheel swing frame of a disc plough, the tail wheel shaft comprises a limiting column embedded in the top of the tail wheel swing frame of the disc plough, a threaded column is provided at the bottom of the limiting column and passes through the bottom of the tail wheel swing frame of the disc plough, a bending column is provided at the top of the limiting column and is placed above the tail wheel swing frame of the disc plough, a connecting shaft is provided at the top of the bending column and is connected to the tail wheel for rotation, and a fastening nut is provided on the side wall of the threaded column and is connected to the tail wheel swing frame of the disc plough to stop the tail wheel shaft.

[0007] Furthermore, the diameter of the threaded column is smaller than the diameter of the bottom of the limiting column, and the diameter of the top of the bending column is larger than the diameter of the bottom of the connecting shaft.

[0008] Further, the connecting shaft is connected to the bearing inside the bearing chamber of the tail wheel.

[0009] Furthermore, a mud scraping assembly is provided on the side wall of the bending column;

[0010] The scraper assembly comprises a fixed block arranged on the side wall of the bending column, the side wall of the fixed block is provided with a scraper plate for scraping mud from the tail wheel, and fixing bolts are arranged between the scraper plate and the fixed block.

[0011] Furthermore, a spare nut is provided on the side wall of the threaded column and is placed below the fastening nut.

[0012] Furthermore, a limiting hole matching the limiting column is provided at the top of the tail wheel swing frame of the disc plow, and a through hole connected to the limiting hole and matching the diameter of the threaded column is provided at the bottom of the tail wheel swing frame of the disc plow, and the upper end surface of the fastening nut is fitted with the bottom surface of the tail wheel swing frame of the disc plow.

[0013] According to the utility model, a disc plow tail wheel bending shaft capable of adjusting the tail wheel angle is provided. By using a bending column of the tail wheel rotating shaft that is bent, when the tail wheel needs to be adjusted, the tail wheel can be driven to rotate by simply rotating the tail wheel rotating shaft and its inclination and deflection angle can be adjusted under the action of the bending of the bending column to achieve a better tillage effect. After the angle is adjusted, the fastening nut sleeved on the side wall of the threaded column is fitted and connected with the tail wheel swing frame of the disc plow, thereby stopping the threaded column to prevent it from rotating, thereby preventing the tail wheel on the tail wheel rotating shaft from rotating, thereby facilitating the angle adjustment and fixing of the tail wheel, and the use effect is good.

[0023] like Figure 1 As shown, the utility model provides a technical solution: a disc plow tail wheel bending axis capable of adjusting the tail wheel angle, comprising:

[0024] A tail wheel shaft 4 is provided on the tail wheel swing frame 2 of the disc plow 1, and the tail wheel shaft 4 includes a limiting column 42 embedded in the top of the tail wheel swing frame 2 of the disc plow 1, a threaded column 41 is provided at the bottom of the limiting column 42 and passes through the bottom of the tail wheel swing frame 2 of the disc plow 1, a bending column 43 is provided on the top of the limiting column 42 and is placed above the tail wheel swing frame 2 of the disc plow 1, a connecting shaft 44 is provided on the top of the bending column 43 and is rotatably connected to the tail wheel 6, and a fastening nut 3 is provided on the side wall of the threaded column 41 and is connected to the tail wheel swing frame 2 of the disc plow 1 to stop the tail wheel shaft 4. This design is achieved by using The bending column 43 of the tail wheel shaft 4 is bent. When the tail wheel 6 needs to be adjusted, the tail wheel 6 can be driven to rotate by rotating the tail wheel shaft 4 and its inclination and deflection can be adjusted under the bending action of the bending column 43 to achieve a better tillage effect. After the angle is adjusted, the fastening nut 3 sleeved on the side wall of the threaded column 41 is fitted and connected with the tail wheel swing frame 2 of the disc plow 1, so as to stop the threaded column 41 and prevent it from rotating, thereby preventing the tail wheel 6 on the tail wheel shaft 4 from rotating, thereby facilitating the angle adjustment and fixing of the tail wheel 6, and the use effect is good.

[0025] Reference Figure 1 and Figure 2The diameter of the threaded column 41 is smaller than the diameter of the bottom of the limiting column 42, and the diameter of the top of the bending column 43 is larger than the diameter of the bottom of the connecting shaft 44. This design facilitates the fastening nut 3 sleeved on the side wall of the threaded column 41 to fit and connect with the tail wheel swing frame 2 of the disc plow 1, and will not be connected with the limiting column 42, thereby improving the stability of the connection.

[0026] Reference Figure 3 The connecting shaft 44 is connected to the bearing 7 inside the bearing chamber of the tail wheel 6. This design improves the rotation stability of the tail wheel 6 by using the bearing 7.

[0027] Reference Figure 1 and Figure 3 , a mud scraping assembly 5 is provided on the side wall of the bending column 43;

[0028] The scraper assembly 5 includes a fixed block 51 arranged on the side wall of the bending column 43, and the side wall of the fixed block 51 is provided with a scraper plate 53 for scraping mud from the tail wheel 6, and a fixing bolt 52 is provided between the scraper plate 53 and the fixed block 51. This design uses the scraper plate 53 to be set on the bending column 43, thereby facilitating the scraper plate 53 to scrape mud from the tail wheel 6.

[0029] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The side wall of the threaded column 41 is provided with a spare nut 31 placed under the fastening nut 3. This design uses the fastening nut 3 and the spare nut 31 to play a secondary fixing and locking role on the threaded column 41 under the action of the spare nut 31. A limiting hole 21 matching the limiting column 42 is opened at the top of the tail wheel swing frame 2 of the disc plow 1, and a through hole 22 connected to the limiting hole 21 and matching the diameter of the threaded column 41 is opened at the bottom of the tail wheel swing frame 2 of the disc plow 1. The upper end surface of the fastening nut 3 is fitted with the bottom surface of the tail wheel swing frame 2 of the disc plow 1. This design facilitates the limiting column 42 to be limited by the limiting hole 21 to prevent the limiting column 42 from passing through the through hole 22. By using the through hole 22, it is convenient for the threaded column 41 to pass through, and then the fastening nut 3 is fitted with the bottom surface of the tail wheel swing frame 2, so that the threaded column 41 is stopped to prevent it from rotating, thereby preventing the tail wheel 6 on the tail wheel shaft 4 from rotating, thereby facilitating the angle adjustment and fixing of the tail wheel 6, and the use effect is good.

[0030] Reference Figure 1-Figure 6As an embodiment of the utility model: when it is necessary to adjust the angle of the tail wheel 6, the staff uses the bending column 43 of the tail wheel shaft 4 to be bent. When the tail wheel 6 needs to be adjusted, it is only necessary to rotate the tail wheel shaft 4 to drive the tail wheel 6 to rotate and adjust its inclination and deflection under the bending action of the bending column 43 to achieve a better tillage effect. When the angle is adjusted, the fastening nut 3 sleeved on the side wall of the threaded column 41 is fitted and connected with the tail wheel swing frame 2 of the disc plow 1, so as to stop the threaded column 41 to prevent it from rotating, and then prevent the tail wheel 6 on the tail wheel shaft 4 from rotating, thereby facilitating the angle adjustment and fixing of the tail wheel 6, and the use effect is good, which improves the practicality of the utility model.
