Description

Technical Field

[0001] This utility model belongs to the field of mounting base technology, specifically relating to an adjustable wear-resistant mechanical parts universal mounting base. Background Technology

[0002] In the field of agricultural machinery, rotary tillers are key wear-resistant mechanical parts, and their performance directly affects the quality and efficiency of tillage operations. With the increasing demands of modern agriculture for precision farming, the adaptability of rotary tillers under different soil types and tillage depths is becoming more and more prominent. This requires the mounting base of the rotary tillers to have flexible adjustment functions.

[0003] Most existing rotary tiller blade mounting seats have a fixed structure, making it difficult to effectively adjust the position and angle of the rotary tiller blades. Although some mounting seats have a certain degree of adjustment capability, the adjustment method is complicated and consumes a lot of time and manpower in actual operation. Moreover, these adjustable mounting seats often cannot provide reliable fixation after the position and angle of the rotary tiller blades are adjusted. During the operation of the rotary tiller, the rotary tiller blades are prone to loosening and displacement due to soil resistance, vibration and other factors. This not only reduces the quality of tillage, resulting in uneven tillage depth and poor soil breaking effect, but may also cause mechanical failure, shorten the service life of the rotary tiller blades and mounting seats, and increase maintenance costs and agricultural production burden.

[0004] Therefore, there is an urgent need for a mounting base that can easily adjust the position and angle of the rotary tiller blades and ensure stability after adjustment, in order to meet the needs of efficient and precise farming in modern agriculture. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable wear-resistant universal mounting base for mechanical parts, which can flexibly adjust the position and angle of the rotary tiller blades to adapt to different soil types and tillage depth requirements; after adjustment, it can ensure connection stability and prevent loosening and displacement during operation.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable wear-resistant universal mounting base for mechanical parts includes a mounting base body on which multiple rotary tillers are mounted. A stepper motor is installed inside the mounting base body. A threaded rod is fixed to the output end of the stepper motor. A movable seat is threadedly connected to the outer side of the threaded rod. A mounting rod, the same number and position as the rotary tillers, is rotatably connected to the outer side of the movable seat. A rotating ball is fixed to the outer side of the mounting rod. A fixing strip is fixed to the bottom of the rotating ball. Multiple rotating grooves are provided on the mounting base body at positions corresponding to the fixing strips. A retaining strip is installed at the bottom of the inner side of the fixing strip. The retaining strip is located in one of the rotating grooves and rotatably connected to the mounting base body.

[0008] A first push rod motor is installed at the top inside the rotating ball. A first chuck is fixed vertically downward on the stroke rod of the first push rod motor. A second chuck is fixed inside the rotating ball at the top of the fixing strip, and the second chuck is engaged with the first chuck. A second push rod motor is installed inside the mounting rod. Multiple slots are provided inside the moving seat at positions corresponding to the second push rod motor. The stroke rod of the second push rod motor extends into one of the slots. An adsorption structure is installed inside the fixing strip for adsorbing the chuck upward.

[0009] The adsorption structure includes a first mounting groove disposed inside the fixing strip, the clip being slidably connected in the first mounting groove, a magnet being fixed to the top of the clip, a first spring being installed inside the first mounting groove and located at the top of the magnet, and the first spring being connected to the fixing strip, and an electromagnet for adsorbing the magnet being assembled at the top of the inner side of the first mounting groove and located inside the first spring.

[0010] Both the first chuck and the second chuck have locking teeth on their adjacent sides, and the two locking teeth engage with each other.

[0011] Both of the two teeth have beveled surfaces on the sides that are close to each other.

[0012] The inner wall of the mounting base body is provided with a second mounting groove on both sides of the rotating ball. A protective plate is slidably connected in the second mounting groove on both sides of the rotating ball. Both protective plates are in contact with the rotating ball. A second spring is installed in the second mounting groove between the protective plate and the mounting base body.

[0013] A soft pad is provided between the two protective sheets.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes the rotation of a threaded rod to move the movable seat back and forth. The use of fixing and locking strips allows for angle adjustment of the rotary tiller blades. Furthermore, by pulling out the locking strips and different rotating slots, the position of the rotary tiller blades can be moved as the movable seat moves, thus achieving flexible adjustment of the blades' position and angle to suit different soil types and tillage depths. After adjustment, the threaded rod and the stepper motor's built-in locking mechanism ensure stable connection, preventing loosening or shifting during operation and improving tillage uniformity and soil breaking effect.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-6As shown, an adjustable wear-resistant mechanical accessory universal mounting base includes a mounting base body 1, on which multiple rotary tillers 2 are mounted. A stepper motor 5 is installed inside the mounting base body 1, and a threaded rod 4 is fixed to the output end of the stepper motor 5. A movable seat 3 is threadedly connected to the outer side of the threaded rod 4. The outer side of the movable seat 3 is rotatably connected to mounting rods 6, which are the same number and position as the rotary tillers 2. Multiple mounting rods 6 at the same position are all driven by the same movable seat 3, ensuring that all rotary tillers 2 move back and forth or adjust their angle synchronously, avoiding single-blade adjustment errors. The mounting rod 6 has a rotating ball 7 fixed to its outer side, and a fixing strip 11 fixed to its bottom. The inner wall of the mounting base body 1 is provided with a sliding groove corresponding to the fixing strip 11, and the mounting base body 1 is provided with multiple rotating grooves at the position of the corresponding sliding groove of the fixing strip 11. A retaining strip 14 is installed at the bottom of the inner side of the fixing strip 11. The retaining strip 14 is located in one of the rotating grooves and is rotatably connected to the mounting base body 1. The rotary tiller 2 is fixed to the outer end of the mounting rod 6 by a detachable bolt. Anti-slip washers are provided at the bolt holes to facilitate quick replacement of worn blades.

[0026] When driven by the stepper motor 5, the threaded rod 4 can be rotated. Through the threaded connection between the threaded rod 4 and the movable seat 3, the movable seat 3 can have a rotational tendency. By setting the rotating ball 7 and the locking strip 14, the movable seat 3 can be limited, so that the movable seat 3 can convert the rotational tendency into a moving tendency, thereby enabling the movable seat 3 to move back and forth. Through the rotational connection between the movable seat 3 and the mounting rod 6, when the movable seat 3 moves, it drives the end of the mounting rod 6 near the movable seat 3 to move forward. With the fixing strip 11 as the fulcrum, the outer rotary tiller 2 swings backward, thereby changing the angle of the rotary tiller 2 and achieving the adjustment effect.

[0027] See attached document Figure 3 A first push rod motor 8 is installed at the top inside the rotating ball 7. A first chuck 9 is fixed vertically downwards on the stroke rod of the first push rod motor 8. A second chuck 10 is fixed inside the rotating ball 7 by the top of the fixing strip 11, and the second chuck 10 is engaged with the first chuck 9. (See attached diagram.) Figure 4Both the first chuck 9 and the second chuck 10 have locking teeth 12 on their adjacent sides, and the two locking teeth 12 engage with each other. This arrangement allows the first push rod motor 8 to drive the first chuck 9 downwards until the locking teeth 12 on the first chuck 9 engage with the groove between the two locking teeth 12 on the second chuck 10. This restricts the second chuck 10 and the fixing bar 11, preventing them from rotating. Consequently, when the rotating ball 7 moves, the fixing bar 11 moves with it instead of rotating in place. Furthermore, the two... Each of the 12 teeth has an inclined surface on one side that is close to each other. This design allows the 12 teeth to rotate along the inclined surface and engage with the 12 teeth on the first chuck 9. The mounting rod 6 is equipped with a second push rod motor 18. The moving seat 3 is equipped with multiple slots at the position corresponding to the second push rod motor 18. The stroke rod of the second push rod motor 18 extends into one of the slots. The fixing strip 11 is equipped with an adsorption structure to adsorb the 14 teeth upward.

[0028] When it is necessary to change the position of the rotary tiller blade 2, the suction structure can be used to move the retaining strip 14 upward, canceling its engagement with one of the rotating slots. At this time, the second push rod motor 18 can be driven to engage with one of the slots, thereby connecting the moving seat 3 and the mounting rod 6 into a whole. Then, the stepper motor 5 is started, causing the stepper motor 5 to drive the threaded rod 4 to rotate. Through the threaded connection between the threaded rod 4 and the moving seat 3, and through the sliding connection between the fixing strip 11 and the sliding groove, the moving seat 3 can drive the rotating ball 7 and the rotary tiller blade 2 to move back and forth as a whole, thereby achieving a sliding effect and changing the position of the rotary tiller blade 2.

[0029] See attached document Figure 5 The adsorption structure includes a first mounting groove 13 disposed inside the fixing strip 11, a clip 14 slidably connected inside the first mounting groove 13, a magnet 15 fixed to the top of the clip 14, a first spring 17 installed inside the first mounting groove 13 and located on the top of the magnet 15, and the first spring 17 is connected to the fixing strip 11, and an electromagnet 16 for adsorbing the magnet 15 is assembled on the top of the inner side of the first mounting groove 13 and located inside the first spring 17.

[0030] When the clamping strip 14 needs to move upward, the electromagnet 16 can be driven to attract the magnet 15, causing the clamping strip 14 to move upward. After the rotary tiller 2 has moved to the appropriate position, the electromagnet 16 can be turned off, causing the first spring 17 to drive the magnet 15 and the clamping strip 14 to reset, thereby causing the clamping strip 14 to spring into one of the corresponding rotating slots, which can provide a fulcrum between the rotary tiller 2 and the moving base 3. The electromagnet 16 is controlled by pulse signals to turn on and off. When energized, it attracts the magnet 15, causing the clamping strip 14 to completely detach from the rotating slot. When de-energized, the first spring 17 quickly resets the clamping strip 14, ensuring adjustment efficiency.

[0031] See attached document Figure 6 A second mounting groove 19 is provided on the inner wall of the mounting base body 1 and on both sides of the rotating ball 7. A protective plate 20 is slidably connected in the second mounting groove 19 and on both sides of the rotating ball 7. Both protective plates 20 are in contact with the rotating ball 7. A second spring 21 is installed in the second mounting groove 19 and between the protective plate 20 and the mounting base body 1.

[0032] With this arrangement, when the rotating ball 7 moves, it can compress one of the second springs 21, and the other protective plate 20, through the setting of the second spring 21, is always in contact with the rotating ball 7, blocking the space around the rotating ball 7 and preventing dirt and other objects from entering the mounting base body 1. The soft pad between the two protective plates 20 makes the contact between the protective plate 20 and the rotating ball 7 better and tighter. The soft pad can be made of materials such as rubber or silicone.

[0033] After the angle and position of the rotary tiller 2 are adjusted, the stability of the rotary tiller 2 can be ensured by setting the threaded rod 4.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
