Description

Technical Field

[0001] This utility model is a grain silo conveying mechanism based on an electronic control system. Background Technology

[0002] Corn is a major grain crop in my country, with a planting area of ​​approximately 300 million mu (13.3 million hectares). In recent years, with the continuous advancement of the national agricultural machinery subsidy policy, the mechanized harvesting rate of corn has been increasing year by year, reducing the intensity of manual labor. As a storage and transfer component of corn harvesters, the transmission efficiency and reliability of the grain silo are crucial. Currently, the grain silo ear conveyor belt transmission structure of similar models on the market is a mechanical structure, where the power transmission is completed by the meshing of the input gear and the drive gear of the ear conveyor belt through the hulling machine's transmission system. This structure is complex, has poor reliability, and is difficult to adjust. Furthermore, because the kernels falling from the hulling machine cannot be lifted into the grain silo, manual unloading is required, which is inconvenient, time-consuming, and increases labor intensity. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grain conveying mechanism based on an electronic control system.

[0004] A grain conveying mechanism based on an electronically controlled system includes a grain lifting mechanism, a grain bin, a peeling mechanism, a hydraulic system, an electronically controlled system, a first motor, and a second motor. The grain lifting mechanism is used to collect and lift corn grains to the grain bin. The hydraulic system is used to provide power to the first motor and the second motor. The electronically controlled system is used to independently control the working state of the first motor and the second motor. The first motor is used to drive the peeling mechanism, and the second motor is used to drive the grain lifting mechanism.

[0005] Furthermore, the hydraulic system includes a hydraulic circuit, a gear pump, an oil tank, and a solenoid valve. The gear pump is connected at both ends to the oil tank and the hydraulic circuit, respectively. The hydraulic circuit is connected to the solenoid valve, and the solenoid valve is connected to the first motor and the second motor.

[0006] Furthermore, the electronic control system includes a first button and a second button, which are used to control the working state of the switching solenoid valve.

[0007] Furthermore, a manual valve is provided between the solenoid valve and the second motor.

[0008] Furthermore, the manual valve is equipped with an operating lever.

[0009] Furthermore, the hydraulic system also includes a filter, which is installed between the gear pump and the hydraulic circuit.

[0010] Beneficial Effects: Compared with existing technologies, this utility model provides power output to the grain silo's corn cob conveyor belt via a hydraulic motor, and a gear pump converts mechanical energy into hydraulic energy, which is then converted back into mechanical energy. This drives two hydraulic motors, transporting the corn cobs from the peeling machine into the grain silo. The corn kernels falling from the peeling machine are collected in a kernel bin below the machine and then conveyed into the grain silo via an elevator. This allows for simultaneous storage of kernels. Furthermore, to facilitate separate bagging of corn cobs and kernels, the kernel elevator motor can be deactivated, allowing the corn cobs to enter the main grain silo while the kernels are stored in the kernel bin. Manual unloading via a mechanical valve ensures the separation of cob and kernel bagging and storage. Attached Figure Description

[0013] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0014] As shown in the figure, there is a first motor 1, a second motor 2, an oil tank 3, a hydraulic oil circuit 4, a solenoid valve 5, a manual valve 6, and an operating lever 7.

[0015] A grain conveying mechanism based on an electronically controlled system includes a grain lifting mechanism, a grain bin, a peeling mechanism, a hydraulic system, an electronically controlled system, a first motor 1, and a second motor 2. The grain lifting mechanism is used to collect and lift corn grains to the grain bin. The hydraulic system is used to provide power to the first motor 1 and the second motor 2. The electronically controlled system is used to independently control the working state of the first motor 1 and the second motor 2. The first motor 1 is used to drive the peeling mechanism, and the second motor 2 is used to drive the grain lifting mechanism.

[0016] In this example, the hydraulic system includes a hydraulic circuit 4, a gear pump, an oil tank 3, and a solenoid valve 5. The gear pump is connected at both ends to the oil tank 3 and the hydraulic circuit 4, respectively. The hydraulic circuit 4 is connected to the solenoid valve 5, and the solenoid valve 5 is connected to the first motor 1 and the second motor 2.

[0017] In this example, the electronic control system includes a first button and a second button, which are used to control the working state of the switching solenoid valve 5.

[0018] In this example, a manual valve 6 is provided between the solenoid valve 5 and the second motor 2.

[0019] In this example, the manual valve 6 is equipped with an operating lever 7.

[0020] In this example, the hydraulic system also includes a filter installed between the gear pump and the hydraulic circuit 4.

[0021] It should be noted that there are two connection points between the manual valve and the second motor. Depending on the direction in which the hydraulic oil enters and exits the second motor, the second motor can rotate forward and reverse. Similarly, there are also two connection points between the manual valve and the solenoid valve. Depending on the connection point from which the hydraulic oil enters the manual valve, the hydraulic oil will be located in different positions within the manual valve. These positions are mainly distinguished by the valve core in the manual valve. In other words, both the solenoid valve and the manual valve have different operating positions. Depending on the combination of these different operating positions, the hydraulic oil has multiple different paths, thereby achieving multiple working states.

[0022] In this structure, the solenoid valve branches into two lines, which lead to the first motor and the manual valve respectively. By controlling the solenoid, hydraulic oil can be controlled to enter the manual valve and the first motor. By controlling the manual valve, hydraulic oil can be controlled to enter the second motor. Thus, the working state of the hydraulic motor can be controlled independently without affecting the operation of other working devices. The first motor and the second motor can work simultaneously, or the second motor can be stopped when the first motor is working. This is achieved by switching between different working positions using the manual valve and the solenoid valve.

[0023] In other words, this structure controls the solenoid valve to switch positions by sending electrical signals via buttons (the first and second buttons correspond to different positions of the solenoid valve) according to production needs, and then manually controls the position of the manual valve via an operating lever, thereby achieving the following two working states:

[0024] The first working state: the first motor and the second motor work simultaneously, with the second motor rotating in the forward direction. The kernels in the kernel box and the corn cobs on the peeling machine are simultaneously transported to the grain bin, and the kernels and corn cobs are stored in the bin at the same time.

[0025] The second working state: the first motor is working and the second motor is not working, so that the kernels remain in the kernel box. Then, the manual valve 6 is operated by the operating lever 7 to reverse the second motor 2, so that the kernels are discharged from the kernel box from the other direction, thus realizing the separation of corn cobs and corn kernels into the silo.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
