[0035] In the embodiment of the utility model, in order to achieve high-precision feeding, improvements are mainly made in three aspects: the positioning accuracy of the working position during the movement of the unloading crane 1, the accuracy of the discharge amount in the material box 14, and the power transmission reliability during the movement of the unloading crane 1.

[0036] like Figure 2 As shown, as an improvement to improve the positioning accuracy of the working position during the movement of the unloading crane 1, a positioning proximity switch 101 is provided on the unloading crane 1, which is electrically connected to the operation control unit 15, and a plurality of positioning blocks 201 ( Figure 2Only one of them is shown), specifically, the origin, work position and turning point (the point at the other end opposite to the origin) in the motion trajectory of the unloading crane 1 are all provided with positioning blocks 201, and an encoder is installed in the operation control unit 15; when the positioning proximity switch 101 reaches each positioning block 201, it will trigger a corresponding electrical signal and transmit the signal to the encoder in the operation control unit 15, so that the position of the unloading crane 1 can be known by the PLC (the specific program coordination method of the PLC, the positioning proximity switch 101 and the encoder is a design that can be directly made by technical personnel in this field in combination with the disclosed content of this scheme, so it will not be repeated here), and the unloading crane 1 can accurately perform corresponding actions at each key working point (origin, work position and turning point).

When the driving wheel 1221 is driven, if the motion sensor 1253 detects that the test wheel 1251 does not rotate synchronously, the PLC in the operation control unit 15 will determine that slipping occurs, the system alarms and stops driving the unloading crane 1 until the operator cancels the alarm and takes action, and the feeding system can continue to operate.
