As shown in fig. 1, the detection channel 201.2 is arranged obliquely so that coins in the detection channel 201.2 rest against the side walls of the detection channel 201.2. When the coin rolls to the coin detecting opening 201.1 formed on the side wall of the detecting channel 201.2, if the size of the coin detecting opening 201.1 is larger than the diameter of the current coin, the coin will drop from the detecting channel 201.2 through the coin detecting opening 201.1. Therefore, a plurality of coin detection ports 201.1 can be arranged, the calibers of the coin detection ports 201.1 are sequentially increased along the moving direction of the coins in the detection channel 201.2, and the coins cannot fall from other coin detection ports 201.1 before reaching the corresponding coin detection ports 201.1, so that the coins are accurately classified. For example, the diameters of the 1 st, old, pentagonal and new 1 st corner are reduced in turn, so that the coin detection ports 201.1 corresponding to the 1 st, pentagonal, old and 1 st corner are respectively arranged along the rolling direction of the coins in the detection channel 201.2, and the 1 st, pentagonal, old and 1 st corner classification detection is realized.

If the judgment result is normal coins, the electromagnet and the intercepting rod 207 do not act, and the coins roll through the detection area smoothly and enter the classification area. Because the diameters of different coins are different, the coins pass through the coin detection port 201.1 on the baffle 201 from small to large, namely a new version 1 corner, a new version 5 corner, an old version 1 corner and a new version 1 yuan in the embodiment. When the coins pass through the coin detection port 201.1 corresponding to each type of coin, the coins fall from the baffle plate 201 to the containing port 211 under the action of gravity, slide through the containing port 211, and switch on the first electrode and the second electrode 211.1 on the containing port 211 to form a counting signal, the BeagleBone Ai control chip 302 receives the counting signal, the number of the coins of the display 104 corresponding to the counting signal is increased by one through the control circuit 304 of the display 104, and the various types of coins obtained through classification finally fall into the storage box.

the coin feeder comprises a feed hopper, a feed disc, a baffle plate, a plurality of through holes, a plurality of coin discharge holes, a plurality of coin detection channels and a plurality of coin detection channels, wherein the through holes with the diameters larger than the diameters of coins are arranged on the feed disc, the bottom of one side surface of the feed disc corresponds to the coin outlet of the feed hopper, coins entering from the coin inlet enter the through holes through the coin outlet under the action of gravity, the other side surface of the feed disc corresponds to the baffle plate, an inclined detection channel is formed on the baffle plate, and the surface of the detection channel is positioned below the lower edge of the through holes at the top of the feed disc;
the motor drives the feed tray rotates, coin in the feed tray is in along with under the restriction of feed tray transports to the position of feed tray top through-hole, under the effect of gravity the coin gets into detection channel, along detection channel surface rolls extremely coin classification recognition device.
3. The intelligent coin counter of claim 1 wherein the intercepting mechanism includes an electrically controlled magnet, a pull rod assembly, and a spring assembly;
the pull rod assembly comprises a fixedly arranged bracket and an intercepting rod which is connected with the end part of the bracket and can rotate around the end part; one end of the intercepting rod is connected with the spring assembly, and the other end of the intercepting rod comprises an intercepting part;
the controller outputs the control signal to the electric control magnet to enable the electric control magnet to control the spring to move towards a first direction, and the spring drives the intercepting rod to rotate around the end of the bracket to enable the intercepting part to move into the detection channel to intercept the abnormal coin; when the control signal disappears, the spring moves towards the direction opposite to the first direction under the action of the elastic force, and the abnormal coin is removed from the detection channel.
4. The intelligent coin counter according to claim 1, wherein the normal coin sorting mechanism includes a plurality of coin detecting ports provided corresponding to the detecting passage provided obliquely, and the apertures of the plurality of coin detecting ports increase in order along the moving direction of the coins in the detecting passage.
5. The intelligent coin counter of claim 4 wherein the normal coin sorting mechanism further comprises a memory in communication with each coin detection port;
the storage is formed with a hollow part for accommodating the coins, and the top of the storage is formed with an accommodating port which is communicated with the coin detection port and the hollow part respectively so that the coins passing through the coin detection port enter the hollow part from the accommodating port.
6. The intelligent coin counter according to claim 5, wherein the accumulator comprises an accumulator housing and a housing provided in the housing, the housing having a top portion forming a recess as the hollow portion;
one side of the housing is formed with a housing opening allowing the housing to pass therethrough.
7. The intelligent coin counter according to claim 5, wherein the receiving opening is shaped to accommodate the coins, the coin counter includes first and second electrodes disposed on opposite sides of the receiving opening, and a counter connected to the first and second electrodes, respectively, wherein when the coins pass through the receiving opening, the first and second electrodes are conducted to form a counting signal, and the controller receives the counting signal to update the number of the coins.
8. The intelligent coin counter according to claim 7, further comprising a plurality of displays corresponding to the abnormal coins and the types of normal coins, respectively;
the counter is used for displaying the number of the coins on the display.
9. The intelligent coin counter of claim 4 further comprising a reset key corresponding to each display and a reset controller for receiving a reset signal generated by a user based on a pressing operation of the reset key to clear the displayed digits of the display.
10. The intelligent coin counter of claim 4 further comprising a power module for powering the coin transport device, coin sorting and identification device, and coin counter.
11. The intelligent coin counter of claim 4 further comprising a housing for housing the coin transport device, coin sorting and identification device, and coin counter.
