[0015] In order to deepen the understanding of the utility model, the utility model will be further described in combination with examples and drawings below, and the examples are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.

[0016] As Figures 1-3 shown, the granary 1, the kernel lifting mechanism 2, the kernel recovery box 3, the insertion plate 4, the stirrer 5, the hydraulic motor 6, the shell 7, the grain outlet 8 and the manual control valve 9;

[0017] A dual-purpose corn machine kernel lifting device, comprising a kernel lifting mechanism 2, a granary 1, a stirrer 5 and a kernel recovery box 3, wherein the kernel recovery box is a coverless box structure, the stirrer 5 is arranged in the kernel recovery box from front to back, one end of the kernel recovery box 3 is provided with a discharge outlet, one end of the stirrer 5 leads to the discharge outlet, the other end of the stirrer 5 is connected with the bottom of the kernel lifting mechanism 2, the top of the kernel lifting mechanism 2 is provided with a grain outlet 8, and the grain outlet 8 leads to the granary 1.

[0018] One end of the shaft of the stirrer 5 is provided with a transmission gear, the transmission gear is connected with a driving gear through a transmission chain, the driving gear is connected with the output end of the hydraulic motor 6, a control valve is arranged on the hydraulic motor 6, the control valve is used for controlling the reverse rotation of the hydraulic motor 6, and the working of the hydraulic motor 6 is controlled by a switch in the cab.

[0019] In the present example, the driving gear is installed on a driving shaft, and the driving shaft is connected with the output end of the hydraulic motor 6 through a shaft coupling.

[0020] In the present embodiment, the grain recovery box 3 has a structure of being wide at the top and narrow at the bottom.

[0021] In the present embodiment, the discharge port of the grain recovery box 3 is provided with a plug plate 4 for blocking the discharge port.

[0022] In the present embodiment, the control valve is a manual control valve 9.

[0023] It should be noted that there are two connection points between the manual valve and the hydraulic motor, and the hydraulic motor can be rotated forward and backward according to the direction of the hydraulic oil entering and exiting the hydraulic motor. Similarly, there are also two connection points between the manual valve and the electromagnetic valve, and the hydraulic oil will be located in different positions of the manual valve according to the different connection points, which are mainly distinguished by the valve core in the manual valve. That is, the electromagnetic valve and the manual valve have different working positions, and the hydraulic oil has different paths according to the combination of the different working positions of the two, so as to realize various working states.

[0024] In the present structure, the electromagnetic valve is connected with the manual valve, and the manual valve is connected with the hydraulic motor. The hydraulic oil can enter the manual valve by controlling the electromagnetic valve, and the hydraulic oil can enter the hydraulic motor by controlling the manual valve, so as to independently control the working state of the hydraulic motor without affecting the operation of other working devices.

[0025] In other words, according to the production demand, the button sends an electric signal to control the electromagnetic valve to switch the working position, and the operating rod manually controls the working position of the manual valve, so as to independently control the forward and backward rotation of the hydraulic motor.

[0026] Working principle: After the corn cob is peeled, a small part of the grain that falls off due to peeling enters the lower grain box of the grain lifting device. The grain has two transmission modes. One is that the main clutch is combined, the motor is rotated forward (the motor switch is pressed), the grain is transported to the grain lifting shell 7 by the grain stirring auger 5 in the lower grain box, the grain lifting chain drives the grain to be lifted upward, and the grain enters the granary 1 through the grain outlet 8. The second is that the main clutch is combined, the motor is not rotated (the motor switch is closed), the grain that falls off from the peeling machine no longer enters the granary 1, and the grain is stored in the lower grain box. As long as the manual control valve is pressed (at this time the motor is reversed), the grain stirring auger 5 can be controlled to reverse to drive the grain to be unloaded, that is, the grain can be directly discharged from the lower grain box.

[0027] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
