Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, specifically a castor bean dehulling machine. Background Technology

[0002] Castor beans can be pressed for oil. The oil has high viscosity and a low freezing point, exhibiting properties unmatched by other oils, including resistance to both extreme cold and high temperatures. It is an important industrial oil used to produce surfactants, fatty acids, glycerides, glycols, drying oils, sebacic acid, stabilizers and plasticizers for polymerization, foamed plastics, and elastic rubber. It is also a raw material for high-grade lubricants. Castor beans can also be used as a medicine, having a mild laxative effect. The oil cake is rich in nitrogen, phosphorus, and potassium, making it a good organic fertilizer. After high-temperature detoxification, it can be used as animal feed. The castor bean stalk bark is rich in fiber and can be used as a raw material for papermaking and rayon production.

[0003] Due to the large quantity of castor beans, manual dehulling is extremely inefficient. Therefore, existing castor dehulling processes typically utilize castor dehulling equipment. Current castor dehulling machines generally include a dehulling machine head with a feed hopper at the top and a discharge port at the bottom. A tumbling and crushing device is rotatably connected to the machine head, driven by a motor. In operation, workers directly feed the castor beans into the feed hopper. The motor drives the tumbling and crushing device to rotate at high speed, breaking the castor beans into shells. The castor kernels and shells are then discharged mixed from the discharge port of the dehulling machine head.

[0004] When using the above-mentioned prior art, the inventors discovered the following problems:

[0005] Existing castor bean dehulling equipment typically produces a mixture of unhulled and partially hulled castor beans, castor kernels, broken castor kernels, and castor husks in the processed material. The unhulled and partially hulled castor beans need to be fed back into the dehulling machine head for secondary dehulling. However, during this secondary dehulling, the existing equipment also processes the unseparated castor husks, which affects the dehulling efficiency and production capacity of the castor beans. Utility Model Content

[0006] The purpose of this invention is to provide a castor bean dehulling machine that reduces the proportion of castor bean husks that are not separated during secondary dehulling, thereby improving dehulling efficiency and production capacity, and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A castor bean dehulling machine includes a support frame on which two dehulling machine heads are mounted. Each dehulling machine head has a corresponding inlet and outlet, and the two dehulling machine heads are placed side by side. A shell, seed, and kernel separator is installed below the dehulling machine heads and is connected to the support frame via a vibration spring. The shell, seed, and kernel separator is connected to a return material assembly, which is connected to the inlet of the separator. The upper outlet of the separator is connected to the two dehulling machine heads.

[0009] Preferably, the material return assembly includes a first material return chute and a second material return chute, which are fixedly connected to a support frame. One end of each material return chute is located below the kernel and husk sorter, and the other end is below the sorter. The sorter is connected to the support frame via a vibration spring. The material return assembly is suspended at the end of the sorter, and the sorter conveys the material away from the material return assembly. The end of the sorter away from the material return assembly is located below the shelling machine head, and an elevator is provided between the sorter and the shelling machine head.

[0010] Preferably, a sorting machine is provided below the kernel and husk sorting machine. The sorting machine is connected to the support frame by a vibration spring. One end of the sorting machine is located below the return material assembly, and the other end is located below the end of the kernel and husk sorting machine near the head of the shelling machine. An elevator is provided between the sorting machine and the head of the shelling machine.

[0011] Preferably, the kernel and husk sorting machine is equipped with a cyclone separator at one end near the return material assembly. The cyclone separator is connected to a fan. The cyclone separator end is covered above the kernel and husk sorting machine, and the other end is connected to the fan. The fan is mounted on a support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model shelling machine adopts a brand-new design, integrating primary shelling, secondary shelling, separation of unshelled kernels and separation of crushed kernels into one unit, and features a compact structure and complete functions.

[0014] 2. After dehulling, all materials enter the shell and kernel sorting machine and the sorting machine for screening. The materials are finely separated by the screens of the shell and kernel sorting machine and the sorting machine itself, which further improves the production capacity.

[0015] 3. During the material transportation process, the combined action of the fan and cyclone separator creates a negative pressure state at the discharge end of the castor bean peel sorter, thereby removing the castor bean peel and eliminating the need for workers to sort the castor bean peel, further improving production capacity.

[0019] 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.

[0020] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a castor bean dehulling machine, including a long strip support frame 6, with two dehulling machine heads 1 mounted on one end of the support frame 6. Each of the two dehulling machine heads 1 has a corresponding feed inlet and discharge outlet, and the two dehulling machine heads 1 are placed side by side.

[0021] Please see Figure 1 and Figure 2 Below the shelling machine head 1, a long strip-shaped kernel and husk separator 2 is installed. The kernel and husk separator 2 is connected to the support frame 6 via a vibration spring. One end of the kernel and husk separator 2 is located below the shelling machine head 1, and the end away from the shelling machine head 1 is equipped with a return material assembly 4. The kernel and husk separator 2 has an upper screen section and a lower screen section. The return material assembly 4 is connected to the feed inlet of the separator 5. A cyclone separator 31 is installed at the end of the kernel and husk separator 2 away from the shelling machine head 1. The cyclone separator 31 is connected to a blower 3. One end of the cyclone separator 31 covers the kernel and husk separator 2, and the other end is connected to the blower 3. The blower 3 is mounted on the support frame 6.

[0022] Please see Figure 1 and Figure 2The return material assembly 4 includes a return material chute 41 and a return material chute 42, which are fixedly connected to the support frame 6. One end of the return material chute 41 and the return material chute 42 is located below the end of the shell and kernel sorting machine 2 away from the head 1 of the dehulling machine, and the other end is provided below a long strip-shaped sorting machine 5. The sorting machine 5 is connected to the support frame 6 by a vibration spring and is arranged parallel to the shell and kernel sorting machine 2. The return material chute 41 and the return material chute 42 are suspended above the starting end of the sorting machine 5, and the sorting machine 5 conveys in a direction away from the return material chute 41 and the return material chute 42. The end of the sorting machine 5 is located below the head 1 of the dehulling machine, and an elevator 61 is provided between the sorting machine 5 and the two head 1s of the dehulling machine.

[0023] Please see Figure 1 and Figure 2 Below the kernel and husk separator 2, there is a long strip separator 5. The separator 5 has a screen section and is connected to the support frame 6 by a vibration spring. One end of the separator 5 is located below the return chute 41 and the return chute 42, and the other end of the separator 5 is located below the kernel and husk separator 2 and extends to the feed port of the elevator 61 near the head 1 of the shelling machine.

[0024] Working principle: The material enters through the feed inlet of the dehulling machine head 1, undergoes centrifugal dehulling inside, and is discharged from the discharge outlet below the dehulling machine head 1, falling into the shell and kernel sorting machine 2. The dehulled material includes unhulled castor beans, castor bean husks, castor beans, and a small amount of broken kernels.

[0025] The castor bean and seed separator 2 has upper and lower screen sections, separating the material into three categories: unhulled castor beans and larger castor husks, castor kernels and smaller castor husks (a small amount of smaller unhulled castor beans), and broken kernels and fine castor husks. Unhulled castor beans and larger castor husks enter the upper screen section, are conveyed by vibration, exit through the middle drain pipe, and enter the return chute 41. They then slide onto the screen surface of the feed end screen section of the separator 5, undergo vibrating screening and conveying, and are discharged from the front upper outlet, entering the feed inlet of the elevator 61. Castor kernels and smaller castor husks (a small amount of smaller unhulled castor beans) enter the lower screen section of the castor bean and seed separator 2, are conveyed by vibration, and enter the rear air chamber. The blower 3 draws air from the rear air chamber to create negative pressure, carrying away the smaller castor beans in the material, which are then discharged through the cyclone separator 31. The remaining material falls from the discharge port into the return chute 42, then slides down to the screen surface of the feed section of the separator 5. After being conveyed by vibration, it is discharged from the front lower discharge port and enters the next process. Crushed kernels and small castor husks enter the lower screen section of the kernel separator 2, are conveyed by vibration, and are discharged from the middle of the separator 2. Through the above technical solution, the efficiency of material separation after dehulling is improved, and the breakage rate of castor kernels during secondary dehulling is reduced. At the same time, the labor intensity of workers is reduced, and production capacity is increased.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
