[0037] The controller in the embodiment can adopt a PLC controller in the prior art, such as a Siemens S7-200CN controller.

[0038] The working principle of the quantitative weighing device of the grain unloading cart is as follows:

[0039] First, a slot for connection is formed on the truck box of the grain unloading cart, and then the unloading mechanism 1 is installed on the truck box of the grain unloading cart, with the unloading port 13 aligned with the slot. When it is necessary to weigh and bag the grain, the support frames 9 at the bottom of the fixed frame 3 are unfolded and placed on the bottom surface, the fixed frame 3 is supported by the support frames 9, and the weighing hopper 2 is aligned with the unloading port 13. The unloading mechanism 1 is started through the foot switch 4, the first driving motor 14 is started, the first blocking door 18 is opened through the first connecting rod 16 and the first pull rod 17, and the grain enters the weighing hopper 2 from the unloading port 13 of the grain unloading cart. The weighing scale 8 measures the weight of the grain in the weighing hopper 2 in real time and sends the data to the controller 5. The controller 5 determines whether the grain reaches the predetermined amount according to the preset quantitative value or the target weight input by the user. When the grain reaches the predetermined amount, the controller 5 sends a signal to the first driving motor 14 to control the first driving motor 14 to reverse, so that the first blocking door 18 is closed through the reversal of the first driving motor 14. Then, when the grain reaches the predetermined amount, the controller 5 sends a signal to the second driving motor, the second driving motor is started, the second blocking door 24 is opened through the second connecting rod 23 and the second pull rod 29, and the grain flows out of the discharge port 25 and enters the external bag. The material guide groove 10 guides the grain to smoothly flow out, thereby reducing splashing or scattering. When the grain completely flows out, the controller 5 sends a signal to the second driving motor again to close the second blocking door 24. The device returns to the initial state and waits for the next use. When the device is not in use, the support frames 9 can be folded through the hinges, thereby reducing the occupied space of the device and facilitating storage and carrying.

[0040] Through the foot switch 4, automatic door opening can be realized, and the user can receive the bagged grain, and the first door 18 will not be opened when the foot switch 4 is not stepped on, so that the operation is very convenient.

[0041] The unloading cart quantitative weighing device realizes the automatic operation of unloading, weighing and quantitative discharging through the cooperation of the controller 5, the weighing scale 8, the driving motor and the door, improves the unloading efficiency and the bagging accuracy, and brings convenience for the breeders and the users who need quantitative bagging.

[0042] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not a limitation on the embodiments of the present application. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description, and all the embodiments cannot be exhausted here. Any obvious changes or variations derived from the technical solutions of the present application still fall within the protection scope of the present application.
