[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] This utility model provides a counting device, such as... Figure 1 and Figure 2 As shown, it may include: a detachably connected housing 1 and a dispensing hopper 2. The housing 1 has an inlet 101 on its upper side and an outlet (not shown) on its lower side. The inlet 101 is connected to the dispensing hopper 2.

[0014] In the embodiments of this utility model, such as Figure 1 As shown, the feeding hopper 2 can be formed into a funnel shape for the objects to be counted to slide into the housing. The feeding hopper 2 can be made of non-woven fabric, making it easy to manufacture feeding hoppers of different sizes according to actual needs, and achieving a flexible connection with the housing. The feeding hopper can be detachably connected to the inlet through snap-fit, bolt connection, or other methods.

[0015] In one illustrative embodiment of this utility model, the object being counted can be a fish, or of course, other objects.

[0016] Furthermore, such as Figure 2 As shown, the housing is provided with a first guide structure and a second guide structure. The first guide structure is formed by a first guide plate 103 and a first baffle 104. The first guide plate 103 is fixedly connected to a first side of the housing and is inclined downward. The first baffle 104 is detachably connected to the first guide plate 103.

[0017] In this embodiment of the invention, the first guide plate 103 is used to allow the object to be counted to slide smoothly into the second guide structure. The tilt angle of the first guide plate can be set according to actual needs. In one illustrative embodiment, the included angle between the first guide plate 103 and the first side can be 60° to 70°, preferably 65°, to ensure that the object to be counted slides smoothly into the second guide structure.

[0018] In this embodiment of the invention, the first baffle 104 is formed as a bent structure that bends toward the second side. Specifically, the first baffle 104 may include a first connecting plate 1041 and a second connecting plate 1042. The upper end of the first connecting plate 1041 is rotatably connected to the upper side of the housing 1, and the lower end of the first connecting plate 1041 is connected to the second connecting plate 1042. The bending angle of the first baffle can be set according to actual needs. In one illustrative embodiment, the first connecting plate 1041 can be rotatably connected to the housing via a rotating shaft. The bending angle θ of the first baffle satisfies the condition: 100°≤θ≤120°, that is, the included angle θ formed by the first connecting plate and the second connecting plate satisfies the condition: 100°≤θ≤120°.

[0019] In this embodiment of the present invention, the first baffle 104 is configured to rotate along the rotation axis under the gravity of the counting object, that is, to open outward to separate from the first guide plate, so that the counting object falls into the second guide structure, and after the counting object slides into the second guide structure, it can rotate back to the initial state under its own gravity, that is, connect with the first guide plate.

[0020] Furthermore, such as Figure 2 As shown, the second guide structure is formed by a second guide plate 105 and a second baffle 106. The second guide plate 105 is fixedly connected to the second side of the housing and is inclined downward. The second baffle 106 is detachably connected to the second guide plate. The first side and the second side are arranged opposite to each other, i.e., opposite to the first side.

[0021] In this embodiment of the invention, the second guide plate 105 is used to allow the object being counted to slide smoothly and steadily, such as... Figure 2 As shown, the second guide plate 105 is formed as a bent structure that bends toward the second side. Specifically, the second guide plate 105 may include a third connecting plate 1051 and a fourth connecting plate 1052. The upper end of the third connecting plate 1051 is fixedly connected to the second side, the lower end of the third connecting plate 1051 is connected to the upper end of the fourth connecting plate 1052, and the lower end of the fourth connecting plate 1052 is fixedly connected to the bottom side of the housing.

[0022] In this embodiment of the utility model, the tilt angle of the second guide plate 105 can be set according to actual needs. In one illustrative embodiment, the included angle between the third connecting plate 1051 and the second side is greater than 30° to ensure that the counting object slides down smoothly.

[0023] Furthermore, in this embodiment of the invention, the second baffle 106 is formed as a bent structure that bends toward the first side. The upper side of the second baffle 106 can be rotatably connected to the first guide plate via a rotating shaft.

[0024] Furthermore, in this embodiment of the invention, the first baffle, the second guide plate, and the second baffle can be formed as a hollow structure to facilitate air permeability and water leakage.

[0025] Furthermore, in this embodiment of the invention, a first magnet (not shown) is provided on the first baffle 104, and a second magnet (not shown) is provided on the second baffle 106; a first magnetic sensor (not shown) is provided on the housing at a position corresponding to the first magnet, and a second magnetic sensor (not shown) is provided on the housing at a position corresponding to the second magnet. Both the first and second magnetic sensors are housed in a control box (not shown) and connected to a circuit board in the control box. When the first baffle is separated from the first guide plate, the positions of the first magnet and the first magnetic sensor do not correspond, and the first magnetic sensor cannot sense the magnetic field of the first magnet. When the second baffle is separated from the second guide plate, the positions of the second magnet and the second magnetic sensor do not correspond, and the second magnetic sensor cannot sense the magnetic field of the second magnet. Only when the baffle is connected to the corresponding guide plate can the magnetic sensor sense the magnetic field of the corresponding magnet.

[0026] In this embodiment of the invention, the magnetic sensor can be a Hall switch or a reed switch, preferably a reed switch which is simple in structure and easy to operate.

[0027] In this embodiment of the invention, the counting of the objects to be counted can be achieved by the opening and closing operation of the first baffle sensed by the first magnetic sensor and the opening and closing operation of the second baffle sensed by the second magnetic sensor. Specifically:

[0028] The object being counted enters the first guide plate through the feeding hopper. Its own gravity pushes the first baffle to rotate, separating it from the first guide plate. At this point, the first magnetic sensor will not detect the magnetic field of the first magnet, recording that the first baffle is in the open state. The object then falls through the sliding opening onto the second guide plate. The first baffle rotates back to its initial position under its own gravity. At this point, the first magnetic sensor will detect the magnetic field of the first magnet, recording that the first baffle is in the closed state. The object falling into the second guide structure will push the second baffle to rotate under its own gravity, separating it from the second guide plate. At this point, the second magnetic sensor will not detect the magnetic field of the second magnet, recording that the second baffle is in the open state. Next, the object slides out of the second guide structure through the outlet. The second baffle rotates back to its initial position under its own gravity. At this point, the second magnetic sensor will detect the magnetic field of the second magnet, recording that the second baffle is in the closed state. Thus, when the operation of opening and closing the first baffle followed by opening and closing the second baffle is detected, the number of objects being counted is recorded as 1, and the total recorded number is incremented by 1.

[0029] Furthermore, such as Figure 1 As shown, the housing is also provided with a mounting base 102 for fixing the housing.

[0030] Furthermore, in another embodiment of the present invention, a counting device is provided. The device provided in this embodiment has a structure that is basically the same as that provided in the foregoing embodiments, except that it also includes a weighing sensor, a locking structure, and a side plate that connects the second baffle and the second guide plate.

[0031] Specifically, in this embodiment, the two sides of the second guide plate and the second baffle are also connected by side plates (not shown) to form a receiving cavity for accommodating the object being counted.

[0032] like Figure 3 As shown, a weighing sensor 112 is provided below the second guide plate 105 for weighing the object being counted.

[0033] Furthermore, in this embodiment, the locking structure is connected to the second baffle and is used to keep the second baffle in a locked state when no control command instructing the second baffle to open is received, and to keep the second baffle in an unlocked state when the control command is received.

[0034] The control commands are generated based on signals sent by the load cell. After the load cell weighs the object being counted, it sends a corresponding signal to the circuit board. At this time, the circuit board sends a control command to the locking structure to open the second baffle.

[0035] Specifically, such as Figure 3As shown, the baffle locking structure may include a third guide plate 107, a guide rod 108, and a locking member 109. The third guide plate 107 has a guide groove 110 for the guide rod to slide. One end of the guide rod 108 is connected to the second baffle 106, and the other end is inserted into the guide groove 110. The third guide plate 107 is formed with a bent structure to allow the second baffle to rotate smoothly. A limiting member 111 is provided in the guide groove 110 to limit the guide rod 108.

[0036] The locking member 109 is disposed on the third guide plate 107, such as Figure 4 As shown, the device includes a telescopic control component 1091 and a telescopic rod 1092. When no control command is received, the telescopic control component 1091 controls the telescopic rod 1092 to block the guide rod 108 to prevent the guide rod 108 from sliding in the guide groove 110. When the control command is received, the telescopic control component 1091 controls the telescopic rod 1092 to separate from the guide rod, so as to allow the guide rod 108 to slide in the guide groove 110.

[0037] In this embodiment of the invention, a stop 1093 is provided on the telescopic rod 1092 to securely block the guide rod. In one illustrative embodiment, the locking member 109 can be an electromagnetic lock, and the specific structure and working principle of the electromagnetic lock can be based on existing technology.

[0038] The working principle of the counting device provided in this embodiment is basically the same as that of the device provided in the previous embodiment. The difference is that when the object to be counted falls into the receiving cavity, because the second baffle is in a locked state, the object to be counted will stay in the second guide structure for a while. After the weighing sensor weighs it, the locking structure will release the lock of the second baffle. At this time, the object to be counted can push open the second baffle and slide out of the housing. Compared with the device provided in the previous embodiment, the device provided in this embodiment also has a weighing function.

[0039] One specific application scenario of the counting device provided in this utility model embodiment is to count the weight of the fish caught by the contestants in a fishing competition, with one counting device corresponding to one contestant.

[0040] Furthermore, the circuit board can communicate with the corresponding mobile terminal to send the quantity and weight of the objects to be counted to the corresponding mobile terminal.

[0041] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should also understand that various modifications can be made to the embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
