Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, specifically a crankshaft-type low-cost buckwheat hulling machine. Background Technology

[0002] Buckwheat is an important grain crop in my country. The protein content of buckwheat flour is significantly higher than that of rice, millet, wheat, sorghum, and corn. Buckwheat flour contains 18 kinds of amino acids, and its fat content is also higher than that of rice and wheat flour. Its fat contains nine kinds of fatty acids, with oleic acid and linoleic acid being the most abundant. In addition, it also contains several organic acids, trace elements, and various vitamins. Buckwheat is rich in protein and vitamins, thus it has the effects of lowering blood lipids, protecting eyesight, softening blood vessels, and lowering blood sugar. At the same time, buckwheat has antibacterial and anti-inflammatory properties, earning it the nickname "anti-inflammatory grain." Furthermore, buckwheat hulls have long been a good material for pillow fillings; long-term use of buckwheat hull pillows is believed to have a cooling and vision-improving effect.

[0003] The current buckwheat hulling process typically uses buckwheat hulling equipment. Existing buckwheat hulling machines usually include a hulling machine head, with a feed hopper at the top and a discharge port at the bottom. A tumbling and hull-breaking device is rotatably connected to the hulling machine head, driven by a motor. In operation, buckwheat falls from the feed hopper into the hulling machine head. Inside the hulling machine head, the motor drives the tumbling and hull-breaking device to rotate at high speed, breaking the buckwheat hull. The buckwheat kernels and hulls are then discharged mixed from the discharge port of the hulling machine head. After passing through a kernel sorting machine and other components, the buckwheat hulls are separated, and the buckwheat kernels proceed to the next process.

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

[0005] Existing buckwheat hulling equipment has a relatively complex structure. Most seed kernel sorters and sorters use a dual-vibration motor drive, which consumes a lot of electricity and is heavy, resulting in high overall manufacturing costs. Utility Model Content

[0006] The purpose of this utility model is to provide a crankshaft-type low-cost buckwheat hulling machine, which reduces the number of motors, optimizes the structure of the kernel sorting machine and the sorting machine, and reduces the weight of the screen body, so as to solve the problems mentioned in the background art.

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

[0008] A crankshaft-type low-cost buckwheat hulling machine includes a support frame on which two hulling machine heads are mounted. Each hulling machine head has a corresponding inlet and outlet, and the two hulling machine heads are placed side by side. A hulling, seed, and kernel sorting machine is installed below the hulling machine heads and is connected to the support frame via a swing arm assembly. A sorting machine is installed below the hulling, seed, and kernel sorting machine and is connected to the support frame via a swing arm assembly. The upper outlet of the sorting machine is connected to the two hulling machine heads.

[0009] Preferably, the side discharge port of the kernel and husk separator is located above the side feed port of the separator, and the discharge end of the kernel and husk separator is located above the feed end of the separator.

[0010] Preferably, the end of the kernel and husk sorting machine away from the head of the shelling machine is equipped with a cyclone separator, which is connected to a fan. The end of the cyclone separator is covered above the discharge end of the kernel and husk sorting machine, and the other end is connected to the fan, which is mounted on a support frame.

[0011] Preferably, the seed and kernel sorting machine is equipped with a drive component at the end of the sorting machine away from the head of the shelling machine. The drive component is mounted on the support frame at the end away from the head of the shelling machine. The drive component includes a motor, a main shaft, an eccentric bushing, etc., and adopts belt drive. The eccentric bushing cooperates with the main shaft to drive the seed and kernel sorting machine to perform cyclic reciprocating motion in the form of a crankshaft.

[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. The optimized kernel sorting machine has a simple structure and light weight, which reduces the equipment manufacturing cost.

[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 crankshaft-type low-cost buckwheat hulling machine, including a long strip support frame 7, with two hulling machine heads 1 mounted on one end of the support frame 7. Each of the two hulling machine heads 1 has a corresponding feed inlet and discharge outlet, and the two hulling 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 7 via a swing arm assembly 5. 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 located above the feed end of the long strip-shaped separator 3. The kernel and husk separator 2 has a layer of screen plates. The side discharge port of the kernel and husk separator 2 is located above the side feed port of the conveying start end of the separator 3. A cyclone separator 41 is installed at the end of the kernel and husk separator 2 away from the shelling machine head 1. The cyclone separator 41 is connected to a fan 4. One end of the cyclone separator 41 covers the kernel and husk separator 2, and the other end is connected to the fan 4. The fan 4 is mounted on the support frame 7.

[0022] Please see Figure 1 and Figure 2 Below the kernel and husk separator 2 is a long strip separator 3. The separator 3 has a screen section. The separator 3 is connected to the support frame 7 through the swing arm assembly 5. One end of the separator 3 is located below the discharge end of the kernel and husk separator 2, and the other end is located below the end of the kernel and husk separator 2 near the head 1 of the dehulling machine. The discharge end of the separator 3 is located above the feed inlet of the elevator 71 near the head 1 of the dehulling machine.

[0023] Working principle: The material enters from the feed inlet on the side of the elevator 71 away from the hulling machine head 1, is conveyed by the elevator 71, and is discharged from the upper discharge outlet into the feed hopper of the hulling machine head 1. After centrifugal hulling inside, it is discharged from the lower discharge outlet of the hulling machine head 1 and falls into the hull and kernel separator 2. The hulled material includes unhulled buckwheat, buckwheat hulls, buckwheat grains, and a small amount of broken kernels.

[0024] The buckwheat and buckwheat hull separator 2 has a screen. After dehulling, the material is separated into two categories by vibrating screening and conveying: one category is unhulled buckwheat and buckwheat hulls; the other category is buckwheat kernels and a small amount of broken kernels. The unhulled buckwheat and buckwheat hulls are above the screen and pass under the end cover of the cyclone separator 41 via vibrating conveying. The blower 4 draws air out from the end cover of the cyclone separator 41 to create negative pressure, carrying away the buckwheat hulls in the material, which are then discharged through the cyclone separator 41. The unhulled buckwheat is discharged from the discharge end of the buckwheat and buckwheat hull separator 2 and falls into the feed end of the kernel separator 3; the buckwheat kernels and broken kernels are below the screen and are discharged from the side discharge port of the buckwheat and buckwheat hull separator 2 via vibrating conveying and fall into the side feed port at the conveying start end of the kernel separator 3.

[0025] The sorting machine 3 has a layer of screen plates. Unhulled buckwheat falls into the feed end, and after being vibrated and screened on the screen plates, it is discharged from the discharge end and falls into the feed port of the elevator 71 near the head 1 of the hulling machine. Buckwheat rice and broken kernels enter the screen plate from the side feed port at the beginning of the conveying process, and after being vibrated and conveyed, they are discharged from the side discharge port at the end of the conveying process and enter the next process.

[0026] Both the buckwheat hulling machine 2 and the sorting machine 3 are connected to the drive assembly 6. The drive assembly 6 includes a motor, a main shaft, and an eccentric bushing, and uses belt drive. The eccentric bushing, in conjunction with the main shaft, drives the buckwheat hulling machine 2 and the sorting machine 3 in a crankshaft-like manner to perform cyclic reciprocating motion. Through the above technical solution, the functions of primary hulling, secondary hulling, separation of unhulled and broken kernels are achieved, while reducing the number of motors, lightening the weight of the equipment, and lowering the equipment manufacturing and operating costs.

[0027] 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.
