Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-Figure 7 The utility model discloses a lobster weighing machine, comprising: a fixed frame 1 arranged on one side of a lobster conveyor belt, and also comprising: a first funnel 2 fixedly mounted on the inner side wall of the fixed frame 1 and near the top position, a second funnel 3 fixedly mounted on the inner side wall of the fixed frame 1 and directly below the first funnel 2, a PID controller 4 for controlling weighing is provided on the outer side wall of the fixed frame 1, a motor valve 5 is provided at the bottom position of the inner cavity of the first funnel 2; a rotating component 6 arranged in the inner cavity of the second funnel 3 and near the bottom position, which is assembled so that when the lobster is being weighed, the rotating component 6 and the bottom outlet end of the second funnel 3 remain parallel and engaged to form a closed bucket for weighing the lobster; when the weight of the lobster in the closed bucket reaches a set value, the motor valve 5 is closed to stop the first funnel 2 from conveying the lobster to the second funnel 3, and the rotating component 6 rotates forward so that the rotating component 6 and the bottom outlet end of the second funnel 3 remain perpendicular to form two discharge holes for discharging lobsters that meet the weight standard.
[0028] Specifically, the first funnel 2 and the second funnel 3 each include a tubular horizontal portion disposed on the upper portion and a tubular inclined portion disposed on the lower portion, and the horizontal portion and the inclined portion are integrally formed.
[0029] In this embodiment, the first funnel 2 and the second funnel 3 are fixed as a whole on the fixing frame 1 by the tubular horizontal portion provided at the top of the first funnel 2 and the second funnel 3. The tubular inclined portion provided at the bottom and integrally formed with the horizontal portion can limit the amount of lobsters output due to the limited size of its outlet end.
[0030] Specifically, the rotating assembly 6 includes a first positive and negative rotating motor 601 symmetrically installed on the outer wall of the inclined part of the second funnel 3 and close to the bottom through a fixed rod. The output end of the first positive and negative rotating motor 601 is fixedly installed with a first rotating rod 602, and one end of the first rotating rod 602 is fixedly installed with a support plate 603, and the top of the support plate 603 is fixedly installed with a weighing plate 604.
[0031] In this embodiment, a first positive and negative rotating motor 601 is symmetrically welded to the bottom of the outer side wall of the inclined portion of the second funnel 3, and a first rotating rod 602 is installed at the output end of the first positive and negative rotating motor 601. A support plate 603 is welded to one end of the first rotating rod 602, thereby providing a fixed space for the weighing plate 604 and providing support for the weighing plate 604. When the lobster on the weighing plate 604 reaches the weight set by the PID controller 4, the PID controller 4 controls the first positive and negative rotating motor 601 to rotate forward, so that the lobsters that meet the weight standard are leaked from the outlet end of the second funnel 3 to the lobster conveyor belt, so as to achieve automatic weighing and uniform discharge after weighing.
[0032] Specifically, the support plate 603 and the weighing plate 604 have the same size, and the sizes of the support plate 603 and the weighing plate 604 are both smaller than the size of the outlet end of the inclined portion of the second funnel 3 .
[0033] In this embodiment, the support plate 603 and the weighing plate 604 are of the same size and slightly smaller than the size of the outlet end of the inclined portion of the second funnel 3, so that the support plate 603 and the weighing plate 604 can prevent the lobster from leaking out of the gap between the support plate 603, the weighing plate 604 and the outlet end of the inclined portion of the second funnel 3, while not affecting the rotation of the support plate 603 and the weighing plate 604 at the outlet end of the inclined portion of the second funnel 3.
[0034] Specifically, a sealing assembly 8 is provided on the inner wall of the horizontal part of the second funnel 3, and the sealing assembly 8 includes a second positive and negative rotating motor 801 fixedly installed on the inner wall of the horizontal part of the second funnel 3 and located at the top position, and a second rotating rod 802 is fixedly installed on the output end of the second positive and negative rotating motor 801, and a sleeve tube 803 is sleeved on the outer wall of the second rotating rod 802, and a sealing plate 804 is fixedly installed on the outer wall of the sleeve tube 803 and located at the bottom position; four groups of mounting grooves 7 and sealing assemblies 8 are provided, and the overall shape of each group of sealing plates 804 is a triangular plate.
[0035] In this embodiment, four groups of second positive and negative rotating motors 801 are welded to the top of the inner wall of the horizontal part of the second funnel 3, and the second rotating rod 802 is installed at the output end of each group of second positive and negative rotating motors 801. The outer wall of each group of second rotating rods 802 is sleeved with a sleeve tube 803. At the same time, a sealing plate 804 with an overall triangular plate shape is welded to the bottom of the outer wall of the sleeve tube 803. When the lobster on the weighing plate 604 reaches the set weight of the PID controller 4, the motor valve 5 is closed, and the PID controller 4 controls the second positive and negative rotating motors 801 to rotate counterclockwise, so that the second positive and negative rotating motors 801 synchronously drive the second rotating rod 802, the sleeve tube 803, and the sealing plate 804 to rotate toward the center position of the inner cavity of the second funnel 3, so that the four groups of sealing plates 804 can be directly engaged with each other to form a closed bucket in the horizontal part of the second funnel 3, thereby preventing the lobster from falling from the gap during the closure of the motor valve 5 and affecting the weighing results.
[0036] Specifically, a mounting groove 7 is provided on the inner wall of the second funnel 3 at the position of the second positive and negative rotating motor 801 . When the lobster is in the weighing state, the blocking plate 804 remains in contact with the inner wall of the horizontal portion of the second funnel 3 .
[0037] In this embodiment, by opening an installation groove 7 on the inner wall of the second funnel 3 and located at the position of the second positive and negative rotating motor 801, installation space can be provided for the second positive and negative rotating motor 801, and when the lobster is in the weighing state, the blocking plate 804 remains in contact with the inner wall of the horizontal part of the second funnel 3, so that the blocking plate 804 will not prevent the lobster from sliding from the inner cavity of the horizontal part of the second funnel 3 to the inner cavity of the inclined part.
[0038] Specifically, a protective sheet 805 is fixedly installed on the outer wall of the sealing plate 804 and at the bottom position, and the overall shape of the protective sheet 805 is consistent with that of the sealing plate 804; the protective sheet 805 is made of rubber material, and the inner wall of the protective sheet 805 and the outer wall of the sealing plate 804 are tightly fitted.
[0039] In this embodiment, a protective sheet 805 made of rubber material is bonded to the bottom of the outer wall of the sealing plate 804 and has the same shape as it, and its inner wall fits tightly with the outer wall of the sealing plate 804, thereby preventing the tips of the four sets of sealing plates 804 from damaging the lobster when they are rotated and engaged.
[0040] Specifically, a transverse fixing frame 9 is fixedly installed on the inner side wall of the fixing frame 1 , and the inner side walls of the transverse fixing frame 9 are fixedly connected to the outer side walls of the inclined portions of the first funnel 2 and the second funnel 3 through connecting rods.
[0041] In this embodiment, a transverse fixing frame 9 is welded to the inner wall of the fixing frame 1, and the inner wall of the transverse fixing frame 9, the outer walls of the inclined parts of the first funnel 2 and the second funnel 3 are fixedly connected by a connecting rod, thereby improving the stability of the first funnel 2 and the second funnel 3 during operation.
[0042] The working principle and use process of the utility model are as follows: when in use, first, the PID controller 4 is used to set the first positive and negative rotating motor 601 to only rotate forward 90 degrees, the weight value of the weighing plate 604, and the blocking plate 804 to only rotate reverse 45 degrees. Then, the first funnel 2 and the second funnel 3 are powered on, so that the lobsters begin to leak from the first funnel 2 to the second funnel 3. Since the bottom of the outer wall of the inclined part of the second funnel 3 is symmetrically welded by the first positive and negative rotating motor 601, and the first rotating rod 602 is installed at the output end of the first positive and negative rotating motor 601, The support plate 603 is welded to one end of the first rotating rod 602, thereby providing a fixed space for the weighing plate 604 and providing support for the weighing plate 604. The two are of the same size and are slightly smaller than the size of the outlet end of the inclined portion of the second funnel 3. As a result, the support plate 603 and the weighing plate 604 can prevent the lobster from leaking out of the gap between the support plate 603, the weighing plate 604 and the outlet end of the inclined portion of the second funnel 3, while not affecting the rotation of the support plate 603 and the weighing plate 604 at the outlet end of the inclined portion of the second funnel 3. When the lobsters on the weighing plate 604 reach the weight set by the PID controller 4, the PID controller 4 controls the motor valve 5 to close, the first positive and negative rotating motor 601 to rotate forward 90 degrees, and the second positive and negative rotating motor 801 to rotate reversely 45 degrees, so that the lobsters that meet the weight standard are discharged from the outlet end of the second funnel 3 to the lobster conveyor belt, and the second rotating rod 802 is installed at the output end of each group of the second positive and negative rotating motor 801. The outer wall of each group of the second rotating rod 802 is sleeved with a sleeve tube 803, and the overall shape is a triangular plate in the initial state. The sealing plate 804 that is in contact with the inner wall of the horizontal part of the second funnel 3 is welded to the bottom of the outer wall of the sleeve 803, so that the second positive and negative rotating motor 801 synchronously drives the second rotating rod 802, the sleeve 803, and the sealing plate 804 to rotate toward the center position of the inner cavity of the second funnel 3, so that the four groups of sealing plates 804 can be directly connected to each other to form a closed bucket in the horizontal part of the second funnel 3, thereby preventing lobsters from falling from the gap during the closing period of the motor valve 5 and affecting the weighing results, so as to achieve automatic weighing and uniform discharge after weighing.
[0043] By welding the transverse fixing frame 9 to the inner wall of the fixing frame 1, and fixing the inner wall of the transverse fixing frame 9, the outer walls of the inclined parts of the first funnel 2 and the second funnel 3 through connecting rods, the stability of the first funnel 2 and the second funnel 3 during operation can be improved.
