Description

Technical Field

[0001] This application relates to the technical field of food processing, and particularly to a metering device for nut production. Background Art

[0002] When producing macadamia nuts, it is necessary to remove the green skin from the picked macadamia nuts and then perform the operation of cracking the shell to obtain the kernels. Enterprises need to monitor the weight ratio of the macadamia nuts after peeling to the weight of the kernels taken out in each batch. The higher this ratio, the cleaner the kernels taken out by the equipment, and at the same time, it also indicates the better quality of this batch. For the kernels, the final output can be obtained by weighing, while for the weight of the macadamia nuts after peeling, a metering tank is required for weighing. After the silo fills the metering tank one by one, it is weighed one by one, and finally the total weight of the macadamia nuts after peeling is obtained. There is a sluice gate between the lower part of the silo and the metering tank, and in order to open and close quickly, a cylinder is often used to switch the sluice gate. The sluice gate is likely to crush the macadamia nuts when closing, causing certain losses. Therefore, a metering device for nut production is needed, which is provided with a buffer plate in the delivery pipe to avoid the sluice gate from cracking the macadamia nuts and improve the integrity of the kernels after kernel extraction. Utility Model Content

[0003] To solve the above problems, this application proposes a metering device for nut production, which is provided with a buffer plate in the delivery pipe to avoid the sluice gate from cracking the macadamia nuts and improve the integrity of the kernels after kernel extraction.

[0024] As Figures 1 to 4 shown, an embodiment of the present invention provides a metering device for nut production, including: a main material bin 1, the main material bin 1 is connected to the ground through a support frame 2, and a discharge pipe 3 is provided at the lower part of the main material bin 1; a metering tank 4, the metering tank 4 is installed on the support frame 2 directly below the main material bin 1, the upper part of the metering tank 4 is provided with an opening, and the lower part of the metering tank 4 is provided with a discharge port, and the lower end of the discharge pipe 3 extends into the metering tank 4; wherein, a buffer plate 5 and a gate plate 6 are provided in the discharge pipe 3, both ends of the buffer plate 5 are connected to the discharge pipe 3 through a connecting shaft 7, and an included angle is provided between the buffer plate 5 and the discharge pipe 3; a guiding groove 8 is provided on the inner wall of the discharge pipe 3, one end of the gate plate 6 is inserted into the discharge pipe 3, and the gate plate 6 is slidably connected to the guiding groove 8, and one end of the gate plate 6 is closely attached to the buffer plate 5.

[0025] After the processing enterprise purchases the green fruits of macadamia nuts from farmers, after peeling and removing sundries such as leaves and branches in the green peel peeling machine, when feeding them into the main material bin 1 through the feeding machine for weighing, the telescopic cylinder 12 extends, thus pulling open the gate plate 6, causing the macadamia nuts in the main material bin 1 to fall into the metering tank 4. After the PLC controller calculates and controls the gate plate 6 to open for 5 s to 10 s, the telescopic cylinder 12 contracts, closing the gate plate 6. After the macadamia nuts finish falling, they are weighed by the weighing sensor 14. After weighing, the macadamia nuts are conveyed to the conveyor belt through the screw conveyor 15. The macadamia nuts are sent into the shelling machine through the conveyor belt to complete the operation of shelling and kernel extraction. The enterprise can calculate the weight ratio of the peeled macadamia nuts to the extracted kernels in this batch by calculating the total weight weighed by the metering tank 4 and the total weight of the extracted kernels. If the ratio is abnormal, the enterprise promptly traces back the reasons.

[0026] When the gate plate 6 is closed, if macadamia nuts are clamped between the end of the gate plate 6 and the buffer plate 5, since there is an angle between the buffer plate 5 and the discharge pipe 3, the macadamia nuts will roll upward. At the same time, the buffer plate 5 will swing under the action of the impact force, so that the clamped macadamia nuts will slide, avoiding the macadamia nuts being cracked by the gate plate 6, improving the integrity of the kernels after kernel extraction. At the same time, when the gate plate 6 is closed, after the buffer plate 5 contacts the gate plate 6, it will compress the spring shock absorber 10 to achieve the purpose of reducing the impact force.

[0027] In a specific embodiment, as Figure 4 shown, both ends of the connecting shaft 7 extend outwards from the discharge pipe 3, and a swing rod 9 is provided on the connecting shaft 7. The swing rod 9 is connected to the outer wall of the discharge pipe 3 through a spring shock absorber 10. When the buffer plate 5 is squeezed by the gate plate 6 or clamps macadamia nuts, the swing rod 9 is driven to swing through the connecting shaft 7. After the swing rod 9 swings, it will compress the spring shock absorber 10 to achieve the purpose of reducing the impact force through the spring shock absorber 10. The spring shock absorber 10 adopts a commercially available spring shock absorber, and its internal compression spring can provide elastic force acting on the swing rod 9, making the buffer plate 5 in an inclined state.

[0028] Specifically, a first limit block 11 is provided on one side of the swing rod 9. One end of the first limit block 11 is connected to the outer wall of the discharge pipe 3. One side of the swing rod 9 is closely attached to one side of the first limit block 11. The first limit block 11 is used to limit the swing rod 9, so that the buffer plate 5 can maintain an appropriate angle under the elastic force of the spring shock absorber 10.

[0029] Preferably, as Figure 3 shown, telescopic cylinders 12 are provided on both sides of the discharge pipe 3. The main body of the telescopic cylinder 12 is fixedly connected to the discharge pipe 3, and the telescopic end of the telescopic cylinder 12 is connected to the gate plate 6. The opening and closing are realized pneumatically, improving the opening and closing speed of the gate plate 6.

[0030] Preferably, a second limiting block 13 is provided on the gate plate 6. When one end of the gate plate 6 is closely attached to the buffer plate 5, the second limiting block 13 abuts against the discharge pipe 3, and the closing position of the gate plate 6 is limited by the second limiting block 13.

[0031] In a preferred embodiment, as Figure 2 shown, a weighing sensor 14 is provided between the metering tank 4 and the support frame 2. The controller calculates the change in the total weight of the metering tank 4 before and after feeding, and thus obtains the amount of macadamia nuts added to the metering tank 4. By adding up the results of each weighing, the total weight of the shelled macadamia nuts can be known.

[0032] Specifically, a screw conveyor 15 is provided at the position of the discharge port at the lower part of the metering tank 4. The feed port of the screw conveyor 15 is communicated with the inner cavity of the metering tank 4. When the screw conveyor 15 stops rotating, the nuts stay in the metering tank 4. After the screw conveyor 15 is started, the nuts in the metering tank 4 can be sent to the conveyor belt or directly lifted and sent to the shelling equipment, realizing the full-automatic operation of the weighing process.

[0033] Certainly, the present application may also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present application.
