Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a frame assembly of a corn harvester. Background Technique

[0002] A corn harvester is an agricultural machinery for mechanically harvesting corn straws. When the corn is mature or nearly mature, according to agronomic requirements, it is an agricultural machinery for mechanically harvesting corn straws. It is a new type of agricultural machinery developed for the development of new energy sources and the reduction of the labor intensity of farmers. It is an agricultural machinery with a low price suitable for the popularization of small four-wheel tractors in rural areas, and can harvest corn straws when equipped. It shortens the labor cycle of farmers and liberates people from heavy physical labor.

[0003] The frame assembly of a corn harvester is a main component of the corn harvester, which can provide a stable working environment for the cab and the storage bin. An auxiliary feeding hydraulic telescopic column is arranged between the existing frame assembly of the corn harvester and the storage bin, and one end of the receiving bin is lifted during the unloading process, so that the harvested corn can fall along the inclined direction of the receiving bin. However, relying solely on the hydraulic telescopic column to lift the storage bin has a large working load, and it is easy to damage the telescopic column structure during the unloading operation of a large amount of materials. Moreover, during the process of storing corn in the storage bin, the corn is stacked in a mountain shape in the storage bin, seriously affecting the storage effect of the storage bin. Therefore, we designed a frame assembly of a corn harvester to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a frame assembly of a corn harvester, which solves the problems put forward in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A frame assembly of a corn harvester includes a frame base, a mounting seat and a storage bin. The mounting seat is fixedly installed on the frame base. The storage bin is sleeved inside the mounting seat. A hydraulic system is assembled on the frame base. A hydraulic telescopic column is connected to the hydraulic system. A telescopic column is sleeved in the hydraulic telescopic column. An activity seat is installed outside the storage bin and is movably connected to the telescopic column. A vibration motor is sleeved in the storage bin. A vibration plate is connected to the outside of the vibration motor. The storage bin and the mounting seat are connected by a deflection rod. A servo motor associated with the deflection rod is fixedly installed outside the mounting seat.

[0006] Furthermore, a discharge inclined plane is arranged at the bottom end of the storage bin. The vibration motors are evenly distributed inside the storage bin. The discharge inclined plane at the bottom end of the storage bin is convenient for the discharge operation of the corn stored in the storage bin when the storage bin deflects. The even distribution of the vibration motors inside the storage bin is convenient for the installation of the vibration plate.

[0007] Further, the vibrating plate is arranged in parallel with the side surface of the storage bin, and inclined end heads are provided at both ends of the vibrating plate. The parallel arrangement between the vibrating plate and the storage bin can prevent the vibrating plate from obstructing the corn entering the storage bin and also prevent the corn from being blocked by the vibrating plate during the discharging process.

[0008] Further, the length value of the vibrating plate is adapted to the length value of the bottom end of the storage bin, and the height value of the vibrating plate is less than the depth value of the storage bin. The length value of the vibrating plate determines the vibration range of the vibrating plate, ensuring that the corn entering the storage bin can be shaken evenly under the vibration of the vibrating plate.

[0009] Further, a fixing frame is connected between the outside of the mounting seat and the servo motor, and the driving part of the servo motor extends to the inside of the mounting seat and is fixedly connected to one end of the deflecting rod. The fixing frame between the mounting seat and the servo motor can ensure the stability of the working environment of the servo motor. The servo motor can drive the deflecting rod to rotate through its driving shaft, thereby assisting the operation of the storage bin to deflect and discharge materials around the deflecting rod.

[0010] Further, a gap is provided between the mounting seat and the storage bin, and the position of the gap corresponds to the position of the discharging inclined surface at the bottom end of the storage bin. The gap between the mounting seat and the storage bin can facilitate the deflecting action of the storage bin, enabling the storage bin to have sufficient space for the deflecting and discharging operation.

[0011] Further, connection notch openings matching the cab of the corn harvester are provided on the outside of the frame base and the cab mounting interface. The notch openings provided on the frame base and the cab mounting interface enable the frame assembly to be connected and assembled with the cab of the corn harvester, thereby forming a complete corn harvester.

[0012] Further, the servo motor and the hydraulic system are symmetrically distributed at the front and rear ends of the storage bin, and the telescopic column is movably connected to the movable seat through a shaft rod. The symmetrical distribution of the servo motor and the hydraulic system can ensure the full effect of the servo motor, the hydraulic telescopic column, and the telescopic column on the storage bin.

[0013] The present utility model provides a frame assembly of a corn harvester, having the following beneficial effects:

[0014] 1. The frame assembly of the corn harvester, through the combined use of hydraulic telescopic columns, telescopic columns, servo motors, and deflection rods, enables the connection between the assembly seat of the frame assembly of the corn harvester and the storage bin through the deflection rod. The storage bin can deflect around the deflection rod under the combined action of the hydraulic telescopic column and the telescopic column, thereby realizing the dumping of the raw materials in the storage bin. At the same time, the servo motor can work and drive the deflection rod to rotate through its drive shaft to assist the deflection action of the storage bin, thereby reducing the working intensity of the hydraulic telescopic column and the telescopic column during the unloading process of the storage bin and avoiding damage to the hydraulic telescopic column and the hydraulic system due to high-intensity work.

[0015] 2. The frame assembly of the corn harvester, through the combined use of the storage bin, vibration motors, and vibrating plates, enables the frame assembly of the corn harvester to store and stack the harvested corn. At this time, the corn is input into the storage bin under the action of the conveying mechanism and stored in a mountain-like pile. At this time, the vibration motors in the storage bin work and drive the vibrating plates to vibrate inside the storage bin, thereby shaking the mountain-like piled corn evenly, making the top of the piled corn flat, making full use of the storage space inside the storage bin, and enabling the storage bin to store more corn.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a frame assembly of a corn harvester, including a frame base 1, an assembly seat 2 and a storage bin 5. The assembly seat 2 is fixedly installed on the frame base 1, and the storage bin 5 is sleeved inside the assembly seat 2. A discharge inclined surface 13 is provided at the bottom end of the storage bin 5. The discharge inclined surface 13 at the bottom end of the storage bin 5 can facilitate the discharge operation of the corn stored in the storage bin 5 when the storage bin 5 deflects. Vibration motors 6 are evenly distributed inside the storage bin 5. The even distribution of the vibration motors 6 inside the storage bin 5 can facilitate the installation of the vibration plate 7.

[0025] A hydraulic system 9 is assembled on the frame base 1. A hydraulic telescopic column 8 is connected to the hydraulic system 9. A telescopic column 14 is sleeved inside the hydraulic telescopic column 8. An activity seat 11 that is movably connected to the telescopic column 14 is installed outside the storage bin 5. And a vibration motor 6 is sleeved in the storage bin 5. A vibration plate 7 is connected to the outside of the vibration motor 6. The vibration plate 7 is arranged parallel to the side surface of the storage bin 5. The parallel arrangement between the vibration plate 7 and the storage bin 5 can prevent the vibration plate 7 from obstructing the corn entering the storage bin 5, and can also prevent the corn from being blocked by the vibration plate 7 during the discharge process.

[0026] Inclined surface ends 12 are provided at both ends of the vibration plate 7. The inclined surface ends 12 at both ends of the vibration plate 7 can facilitate the guiding of the corn by the vibration plate 7. The length value of the vibration plate 7 is adapted to the length value of the bottom end of the storage bin 5. The length value of the vibration plate 7 determines the vibration range of the vibration plate 7, ensuring that the corn entering the storage bin 5 can be shaken evenly under the vibration of the vibration plate 7. And the height value of the vibration plate 7 is less than the depth value of the storage bin 5. The height value of the vibration plate 7 being less than the depth value of the storage bin 5 can prevent the vibration plate 7 from protruding from the storage bin 5 and being damaged.

[0027] Please refer to Figures 2 to 6 , the storage bin 5 is connected to the assembly seat 2 through a deflection rod 4. A servo motor 3 associated with the deflection rod 4 is fixedly installed outside the assembly seat 2. A fixing frame is connected between the outside of the assembly seat 2 and the servo motor 3. The fixing frame between the assembly seat 2 and the servo motor 3 can ensure the stability of the working environment of the servo motor 3. The drive of the servo motor 3 extends to the inside of the assembly seat 2 and is fixedly connected to one end of the deflection rod 4. The servo motor 3 can drive the deflection rod 4 to rotate through its drive shaft, thereby assisting the operation of the storage bin 5 to deflect and discharge around the deflection rod 4.

[0028] A gap is provided between the assembly seat 2 and the storage bin 5. The gap between the assembly seat 2 and the storage bin 5 facilitates the deflection action of the storage bin 5. The position of the gap corresponds to the position of the discharge inclined plane 13 at the bottom end of the storage bin 5, enabling the storage bin 5 to have sufficient space for deflection and discharging operations. Connection notches matching the cab of the corn harvester are provided on the outside of the frame base 1 and the cab assembly interface 10. The notches provided on the frame base 1 and the cab assembly interface 10 enable the frame assembly to be connected and assembled with the cab of the corn harvester, thus forming a complete corn harvester.

[0029] The servo motor 3 and the hydraulic system 9 are symmetrically distributed at the front and rear ends of the storage bin 5. The symmetrical distribution of the servo motor 3 and the hydraulic system 9 can ensure the full action of the servo motor 3, the hydraulic telescopic column 8, and the telescopic column 14 on the storage bin 5. The telescopic column 14 is movably connected to the movable seat 11 through a shaft rod. The shaft rod between the telescopic column 14 and the movable seat 11 can ensure the deflection between the telescopic column 14 and the movable seat 11 when the telescopic column 14 jacks up the storage bin 5, ensuring the progress of the jacking action.

[0030] In summary, for the frame assembly of this corn harvester, during use, the frame assembly is combined with its harvester accessories to form a complete corn harvester. Corn is input into the storage bin 5 by the conveying mechanism of the harvester and stored in a pile. At this time, the vibration motor 6 in the storage bin 5 works and drives the vibration plate 7 to vibrate inside the storage bin 5, thereby shaking the mountain-shaped piled corn evenly, making the top of the piled corn flat, making full use of the storage space inside the storage bin 5, enabling the storage bin 5 to store more corn. The assembly seat 2 and the storage bin 5 are connected through a deflection rod 4. When the corn in the storage bin 5 is full and needs to be discharged, the hydraulic system 9 can work and make the telescopic column 14 in the hydraulic telescopic column 8 extend under the action of hydraulic pressure, causing the storage bin 5 to deflect around the deflection rod 4 under the combined action of the hydraulic telescopic column 8 and the telescopic column 14, realizing the dumping of the raw materials in the storage bin 5. At the same time, the servo motor 3 works and drives the deflection rod 4 to rotate through its drive shaft, assisting the deflection action of the storage bin 5, reducing the working intensity of the hydraulic telescopic column 8 and the telescopic column 14 during the discharging process of the storage bin 5, and preventing the hydraulic telescopic column 8 and the hydraulic system 9 from being damaged due to high-intensity work. The corn in the storage bin 5 pours out along the discharge inclined plane 13 and the inclined direction of the storage bin 5, completing the working process of the entire frame assembly of the corn harvester.
