In other embodiments, the number of the columns 21 may be determined according to the shape of the hopper 10, for example, if the cross section of the hopper 10 is a prototype, the number of the columns 21 may be three or six.

In the preferred embodiment, the plurality of columns 21 are symmetrically arranged about the center of gravity of the hopper 10, so that the amount of gravity center offset of the hopper 10 can be calculated from the pressure values of the hopper 10 received by the plurality of columns 21 in combination with the inclination angle value of the hopper 10.

The frame 20 further comprises a chassis 23, and the upright 21 is arranged on the chassis 23.

The rack 20 further includes at least one cross bar 22, two ends of the cross bar 22 are respectively connected to the two columns 21, and the inclination angle detecting part 30 is disposed on the cross bar 22.

As shown in fig. 1 and 5, in the present embodiment, the frame 20 includes three beams, the beams are connected to the tops of the columns 21, and the inclination angle detecting portion 30 is provided on the upper surface of one of the beams.

In order to more accurately obtain the inclination angle of the position of the weighing parts 40, the inclination angle detecting part 30 is preferably provided on a plane on which the detection surfaces of the plurality of weighing parts 40 are located.

When the hopper 10 is in a horizontal state, the sum of the pressure values measured by the four weighing parts 40 is the weight of the hopper 10.

Since the pressure values measured by the four weighing parts 40 are smaller when the hopper 10 is in the inclined state than when the hopper 10 is in the horizontal state, the pressure values measured by the weighing parts 40 need to be adjusted by using the inclination angle of the hopper 10 with respect to the horizontal plane, which is detected by the inclination angle detecting part 30, to obtain a more accurate weight of the hopper 10.

If the inclination angle of the hopper 10 in the X direction is α, the inclination angle in the Z direction is β, and the pressure values measured by the four weighing sections 40 are G1, G2, G3 and G4, respectively, the actual weight M of the hopper 10 can be obtained by using the following formula:

M＝(G1+G2+G3+G4)/(cosα·cosβ)。

Stopping feeding the hopper 10 when the measured actual weight of the hopper 10 is greater than the upper limit alarm value; when the measured actual weight of the hopper 10 is less than the lower alarm limit, the discharge of the hopper 10 is stopped.

The method for stopping the discharging of the hopper 10 is that the first control part controls the push rod 11 of the discharging door to move, and the push rod 11 drives the baffle 12 to close the outlet of the hopper 10.

In addition, the first control unit displays data such as the pressure values measured by the respective weighing units 40, the inclination angle of the hopper 10 measured by the inclination angle detection unit 30, and the calculated weight of the hopper 10 on a display, and transmits the data to an upper computer through a communication circuit.

That is, when the measured actual weight of the hopper 10 is greater than the upper limit alarm value, the feeding of the hopper 10 is stopped.

The method of stopping the feeding of the hopper 10 includes stopping the discharging of the stock section while stopping the operation of the feed section.

The second control unit can also control the feeding of the hopper 10 according to the position of the center of gravity of the hopper 10.

In this embodiment, the aquatic bait casting device further comprises a second control part, the weighing part 40 and the inclination angle detection part 30 of the hopper device are electrically connected with the second control part, and the second control part calculates the gravity center position of the hopper device according to data measured by the weighing part 40 and the inclination angle detection part 30, and controls the start and stop of the feeding part according to the gravity center position of the hopper device.

When the hopper 10 is inclined, the center of gravity of the hopper 10 is shifted according to the inclination, and if the amount of shift is too large, the stability of the hopper 10 is insufficient, and a rollover accident is likely to occur.

As shown in fig. 6, if the center of gravity of the hopper 10 is higher than the chassis 23 and the projection of the center of gravity is located outside the chassis 23, the hopper 10 may turn over, so that an early warning range is set, the area of the early warning range is 80% to 90% of the area of the chassis 23, and when the center of gravity of the hopper 10 is detected to exceed the early warning range, the feeding of the hopper 10 is stopped.

The Y direction is set to be orthogonal to the X direction and the Z direction, i.e., the X direction, the Y direction, and the Z direction are three-dimensionally orthogonal.

As shown in fig. 6, if the pressure values measured by the four weighing sections 40 are G1, G2, G3 and G4, respectively, the pressure value measured by the weighing section 40 located on the upper right side in fig. 6 is G1, the pressure value measured by the weighing section 40 located on the upper left side in fig. 6 is G2, the pressure value measured by the weighing section 40 located on the lower right side in fig. 6 is G3, and the pressure value measured by the weighing section 40 located on the lower left side in fig. 6 is G4.

If the inclination angle of the hopper 10 in the X direction is α, the inclination angle in the Z direction is β, a is half the distance between the two columns 21 in the X direction, b is half the distance between the two columns 21 in the Z direction, and M is the weight of the hopper 10, the offset amounts of the center of gravity of the hopper 10 in the X direction, the Z direction, and the Y direction can be calculated by the following equations:

Xm＝(G1+G3-G2-G4)·a/M；

Zm＝(G1+G2-G3-G4)·b/M；

Ym＝{(G1+G2-G3-G4)·a·cotα/M}-{(G1+G2-G3-G4)·a·cscα/M}；

Ym＝{(G1+G2-G3-G4)·b·cotβ/M}-{(G1+G2-G3-G4)·b·cscβ/M}。

when Xm is larger than 0.8a or Zm is larger than 0.8b, the gravity center of the hopper 10 exceeds the early warning range, and the second control part stops the operation of the feeding part to stop feeding of the hopper 10.

In addition, the aquatic bait casting device of the invention can also adjust the upper limit alarm value for comparing with the weight of the hopper 10 according to the gravity center position of the hopper 10, and the specific operation flow is as follows:

program initialization is carried out before the overwater bait casting device operates, an upper limit alarm value and a lower limit alarm value of the weight are set, manual setting and automatic assignment can be carried out manually, and then the overwater bait casting device starts to operate.

During the operation of the aquatic bait casting device, the weighing part 40 and the inclination angle detection part 30 detect in real time, and transmit the detected data to the first control part and the second control part, and the second control part calculates the gravity center position of the hopper 10 according to the method. When the position of the center of gravity exceeds the allowable range, stopping the operation of the feeding part; when the position of the center of gravity is within the allowable range, the upper limit alarm value is adjusted downwards according to the deviation of the center of gravity, and the larger the deviation of the center of gravity is, the larger the amplitude of the upper limit alarm value is adjusted downwards.

The first control part calculates the weight of the hopper 10, and stops the operation of the feeding part when the weight is greater than the upper limit alarm value; when the weight is smaller than the lower limit alarm value, the first control part controls the blanking door to close.

The aquatic bait casting device can be arranged on a ship and also can be arranged on an aquatic floating platform, and is suitable for aquaculture industry.
