[0002] Guava, a tree of the Myrtaceae family, can reach up to 13 meters in height. Its bark is smooth, gray, and peels off in flakes. Young branches are angular and hairy. Leaves are leathery, oblong to elliptic, with an acute or obtuse apex and a nearly rounded base. The upper surface is slightly rough, and the lower surface is hairy. There are 12-15 pairs of lateral veins, often sunken, with prominent reticulate veins. The petiole is 5 mm long. Flowers are solitary or in cymes of 2-3. The calyx tube is campanulate and hairy, with the calyx cap irregularly split. Petals are white. Stamens are 6-9 mm long. The ovary is inferior, fused with the calyx. The style is the same length as the stamens. The berry is globose, ovoid, or pear-shaped, with persistent sepals at the apex. The pulp is white or yellow, with a large, fleshy, pale red placenta. Seeds are numerous.
[0003] Guava is currently a common food in people's lives. However, since the pulp and seeds of guava grow together, it is inconvenient to eat. At present, the separation of guava seeds and pulp is done manually, which is quite troublesome, seriously affecting the efficiency of seed and pulp separation and reducing the consumption rate. Therefore, we propose a guava pulp and seed separation device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a device for separating guava pulp and seeds, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5In this utility model, the guava pulp and seed separation device includes a separation tank 1. A separation component 2 is connected to one side of the separation tank 1. The separation component 2 includes a sealed bearing 201. A positioning rod 202 is connected to the inner ring of the sealed bearing 201. A power motor 203 is connected to one end of the positioning rod 202. Two slides 205 are provided on the inner side wall of the separation tank 1. An annular groove 204 is provided on the inner side wall of the separation tank 1. A separation chamber 206 is provided above the separation tank 1. A fixed groove 207 is provided on one side of the separation chamber 206. Two mounting seats 20 are connected to one side of the separation tank 1. 8. Each mounting base 208 has an electric push rod 209 embedded on one side. One end of two electric push rods 209 is connected to a mounting plate 210. A servo motor 211 is connected to one side of the mounting plate 210. One end of the servo motor 211 is connected to a support plate 212. A set of separating rods 213 is connected to one side of the support plate 212. Two positioning blocks 214 are connected to the outer surface of the separating chamber 206. The positioning blocks 214 are adapted to the slide rail 205. An annular groove 204 is adapted to the positioning blocks 214 and is connected to the slide rail 205. The separation chamber 206 is easily disassembled and installed, and its interior can be cleaned. Combined with the pushing force of the electric push rod 209, the separation rod 213 can be inserted into the separation chamber 206 and the pomegranate. The support plate 212 can cover the separation chamber 206, and the start of the servo motor 211 can cause the separation rod 213 to cut the pomegranate into pieces. Through the rotation of the power motor 203, the matching of the positioning rod 202 and the fixed groove 207, and the use of the sealed bearing 201, the separation chamber 206 can rotate at high speed. Combined with the high speed of the separation chamber 206... The rotation allows guava seeds to fly out of the holes in the separation chamber 206 and be stored in the separation tank 1. During the separation process, since the guava seeds are basically the same size, there is no size difference in practice. Furthermore, since the holes in the separation chamber 206 are adapted to the size of the guava seeds, the size of the guava pieces is generally larger than the diameter of the holes in the separation chamber 206. Therefore, the guava seeds can pass through the holes in the separation chamber 206 smoothly, while the guava pieces cannot. This increases the efficiency and quality of separating the pulp and seeds and reduces the amount of labor involved.
[0024] Each separating rod 213 has a set of auxiliary separating holes 4 on its outer surface. The fixed groove 207 is adapted to the positioning rod 202. The auxiliary separating holes 4 can improve the quality and efficiency of pulp and seed separation. The outer surface of the separating tank 1 is inlaid with an observation window 3. Each slide 205 is connected to the annular groove 204. The observation window 3 can be used to easily observe the separated pulp. A set of support frames 8 is connected to one side of the separating tank 1. Each support frame 8 has anti-slip texture on one side. The support frame 8 can be used to easily support the equipment.
[0025] One side of the separator 1 is connected to an electromagnetic discharge valve 7. The fixed groove 207 is adapted to the positioning rod 202. The electromagnetic discharge valve 7 can be used to conveniently discharge the separated seeds. One side of each electric push rod 209 is connected to a connecting block 5. One side of each connecting block 5 is connected to one side of the mounting plate 210. The connecting block 5 can increase the connection between the electric push rod 209 and the mounting plate 210. One side of the separator 1 is connected to a control display screen 6. Each positioning block 214 is adapted to the slide 205. The control display screen 6 can be used to conveniently set the operation of the electrical components.
[0026] The working principle of this utility model is as follows:
[0027] First, the device is transported to the location of use, and the electrical components are connected to the power supply. The positioning block 214 is inserted into the slide rail 205, and the positioning rod 202 is inserted into the fixed groove 207. The pomegranates to be separated are placed into the separation chamber 206. Then, the electric push rod 209 is activated to insert the separation rod 213 into the separation chamber 206. The support plate 212 covers the separation chamber 206, and the servo motor 211 and the power motor 203 are activated. The rotation of the servo motor 211 causes the separation rod 213 to cut the pomegranates into pieces. At the same time, the rotation of the power motor 203 causes the positioning rod 202 and the separation chamber 206 to be in a high-speed centrifugal force, so that the seeds enter the separation tank 1 through the holes of the separation chamber 206 for storage. Then, the seeds can be discharged through the electromagnetic discharge valve 7. At the same time, the mounting plate 210 and the separation rod 213 can be raised to remove the separation chamber 206 and then the fruit pieces can be removed. The above is the complete usage process of this utility model.
