[0027] The control box 10 is internally provided with a frequency converter and an AC contactor, and externally provided with a switching button.
[0028] The conveying belt 2 is provided with a hollow structure, and is made of nylon material, which is used to remove more water during the conveying of fish or shrimp.
[0029] The vertical partition plate 3 uniformly distributed on the conveying belt 2 has a height less than the maximum space height between the rack 1 and the bottom port of the feeding hopper 8, and a width less than the width of the conveying belt 2. Figure 3 and Figure 4 The structure shown in the drawings facilitates the smooth passing of the conveying belt 2 during the conveying of materials.
[0030] In order to prevent the sinking of the conveying belt 2, a support frame is arranged at the lower layer of the conveying belt 2, and the length of the support frame accounts for one third of the length of the lower layer of the conveying belt 2. The support frame is connected with the upper cross beam 9 of the rack 1, and is composed of four vertical rods 19 and two horizontal rods 20, and the two horizontal rods 20 are made of angle steel structure. Figure 3 The structure shown in the drawings facilitates the smooth passing of the conveying belt 2 during the conveying of materials.
[0031] A horizontal supporting plate structure (not shown in the drawings) for supporting the upper layer of the conveying belt 3 can also be arranged at the inner side of the two upper cross beams 9.
[0032] In the embodiment, the weighing sensor 15 is connected with the controller in the control box 10, the controller is connected with the frequency converter, the frequency converter is connected with the AC contactor through a line, and the AC contactor is connected with the conveying belt motor 18 through a line.
[0033] The control box 10 is externally provided with a rotary knob switch having two states of opening and stopping, which is used to control whether the frequency converter is connected or not.
[0034] When the conveyed materials, such as fish, shrimp and other weights, first fall slowly on the conveying belt 2 through the feeding hopper 8, the materials are uniformly dispersed through the vertical partition plate 3 on the conveying belt 2. Figure 1In the process of moving from right to left (the direction of the running of the conveyor belt 2 is regarded as the front end, wherein the running direction of the conveyor belt 2 is indicated by the arrow D), the material is slowly conveyed into the tray 14 embedded above the weighing disc 5, when the material in the tray 14 reaches the set weight, the weighing sensor 13 transmits a signal to the conveyor belt motor 18 to stop rotating, the conveyor belt 2 stops moving forward, the tray 14 is transferred to the next process, and another empty tray 14 is placed on the weighing sensor 13, the conveyor belt motor 18 circuit is connected, and the conveyor belt 2 continues to convey the material forward; such a cycle can better apply to small and medium-sized enterprises, which is convenient and flexible, improves the weighing accuracy, and reduces the labor intensity.
[0035] In this embodiment, the weighing disc 15 and the weighing sensor 13 are placed on the placing frame 16 according to the actual height of the rack 1, if the height of the rack 1 is low, the placing frame 16 can be completely saved, or the bottom support legs of the placing frame 16 can be made slightly shorter, because the upper surface of the placing frame 16 is generally flatter than the foundation or the ground, so that the weighing is more accurate. Embodiment 2:
[0036] A kind of automatic weighing conveyor, such as Figure 5 The structure shown in the figure, wherein: rack 1, conveyor belt 2, vertical partition 3, driven synchronous pulley 4, driven synchronous belt bearing seat 5, adjusting screw 6, nut 7, feeding hopper 8, upper beam 9, control box 10, driving synchronous belt bearing seat 11, speed reducer 12, weighing sensor 13, tray 14, weighing disc 15, placing frame 16, driving synchronous pulley 17, conveyor belt motor 18, vertical rod 19, cross bar 20, long hole 21, first connecting piece 22, second connecting piece 23, connecting seat 24, hinged shaft 25, spring 26, guard plate 27.
[0037] The difference from embodiment 1 is that a connecting seat 24 is additionally provided at the front end of the driving synchronous belt bearing seat 11 (the direction of the running of the conveyor belt 2 is regarded as the front end, wherein the running direction of the conveyor belt 2 is indicated by the arrow D), and a guard plate 27 with a triangular structure with rounded corners is hinged on the connecting seat 24 through a hinged shaft 25, and the guard plate 27 is shown in the attached Figure 5The structure placed in the middle is connected with the upper cross beam 9 of the rack 1 by adding a spring 26, the pulling force of the spring 26 is suitable for preventing the rotation of the guard plate 27 around the hinge shaft 25, of course, in order to also use the convenient pull hook structure instead of the spring 26 in the embodiment, the guard plate 27 is connected to the upper cross beam 9 of the rack 1 through the pull hook. The structure of the embodiment is used when the volume of the conveyor is large. The guard plate 27 is also placed on the driven synchronous belt bearing seat 11 on both sides, if the volume of the conveyor is too large, the guard plate 27 at this time plays a role in preventing the material from scattering outward; if the slow advancing process of the conveyor belt 3 is affected by the forward thrust of the material, the scattering phenomenon occurs, then the structure of adding a guard plate on the left side of the tray is also feasible.
[0038] The utility model is not limited to the protection scope listed above, any connection structure using the weighing sensor 13 connected below the weighing disc 15 to control the start and stop of the conveyor belt motor 18 is regarded as being within the protection scope of the utility model. Similarly, the structure recorded in the above embodiment is also applicable to the quantitative weighing of other materials.
