Description

Technical Field

[0001] This utility model relates to the technical field of agricultural product hulling equipment, specifically a highly stable 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 a buckwheat hulling machine. Existing buckwheat hulling machines usually employ a grinding and rolling method. The machine mainly consists of an outer cylinder, upper cover, bottom plate, rotating shaft, fixed wheel, moving wheel, bearing sleeve, discharge port, and gap adjustment device. Both the fixed and moving wheels are grinding wheels. The fixed wheel is installed below the gap adjustment device, and the moving wheel is positioned below the fixed wheel, mounted on the rotating shaft. There is a certain gap between the moving and fixed wheels. In operation, an external motor drives the rotating shaft at high speed via a belt, which in turn drives the moving wheel at high speed. Buckwheat falls into the hulling machine from the inlet. When it reaches the cavity between the moving and fixed wheels, under centrifugal force, it passes through the gap between the wheels and is crushed and rolled by the wheels, completing the hulling process. The crushed material is discharged from the hulling machine's outlet and proceeds to the next process.

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

[0005] There are two existing methods for fixing the fixed wheel in buckwheat hulling machines. One method involves installing several vertical fixing plates below the gap adjustment device. These plates have threaded holes, and bolts pass through these holes to connect to the cylindrical surface of the fixed wheel, securing it between the plates. The other method involves machining threads on the lower part of the gap adjustment device and installing two threaded rings on these threads. The fixed wheel passes through these threads, and tightening the two rings secures it to the lower part of the gap adjustment device. Both of these installation methods are susceptible to vibrations generated during machine operation, leading to bolt and ring loosening. This affects the stability of the hulling machine and reduces its hulling efficiency and capacity. Utility Model Content

[0006] The purpose of this invention is to provide a highly stable buckwheat hulling machine that reduces the possibility of the fixed wheel loosening, improves hulling efficiency and production capacity, and solves the problems mentioned in the background art.

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.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a highly stable buckwheat hulling machine, including a cylindrical outer cylinder 7, which is welded to a base plate 12. The base plate 12 has a material leakage hole, and a material outlet 22 is welded and fixed below the material leakage hole.

[0017] Please see Figure 1 and Figure 2 A bearing seat 13 is provided at the lower center of the base plate 12. A pressure cap 1 20 and a pressure cap 2 21 are provided above and below the bearing seat 13. A rotating shaft 18 is provided in the bearing seat 13. The rotating shaft 18 is connected to the bearing seat 13 through bearings 1 14, 2 15, pressure caps 1 20 and 2 21 and rotates smoothly.

[0018] Please see Figure 1 and Figure 2 A rotating shaft 18 has a rotating wheel 10 on its upper part and a sealing cover 19 below the rotating wheel 10. The rotating wheel 10 and the sealing cover 19 are fixed to the rotating shaft 18 by two set nuts 11 and washers 17. A pulley 16 is provided at the lower part of the rotating shaft 18.

[0019] Please see Figure 1 and Figure 2 The outer cylinder 7 is provided with an upper cover 6, which is connected to the outer cylinder 7 by bolts. The upper cover 6 has a threaded hole in the center, and a fixed wheel sleeve 3 is provided in the threaded hole. A locking nut 4 is provided above the threaded hole of the upper cover 6.

[0020] Please see Figure 1 and Figure 2 An adjustment handle 1 is provided on the upper part of the fixed wheel sleeve 3. The adjustment handle 1 is connected to the fixed wheel sleeve 3 by a fixing bolt 2. A scale 5 is provided on the upper part of the upper cover 6. A fixed wheel 9 is provided on the lower part of the fixed wheel sleeve 3.

[0021] Please see Figure 1 and Figure 2 The fixed wheel 9 is fixed to the pad 8 between the fixed wheel sleeve 3 by bolts, and the fixed wheel 9 is positioned above the moving wheel 10.

[0022] Working Principle: An upper cover 6 is installed on the upper part of the outer cylinder 7, and the upper cover 6 is connected to the outer cylinder 7 by bolts. The upper cover 6 has a threaded hole in its center, into which a fixed wheel sleeve 3 is installed. A locking nut 4 is installed above the threaded hole of the upper cover 6. An adjusting handle 1 is installed on the upper part of the fixed wheel sleeve 3, and the adjusting handle 1 is connected to the fixed wheel sleeve 3 by fixing bolts 2. A scale 5 is installed on the upper part of the upper cover 6, and a fixed wheel 9 is installed at the lower part of the fixed wheel sleeve 3. A pad 8 is installed below the inner ring of the fixed wheel 9. The fixed wheel 9 is fixed to the fixed wheel sleeve 3 by multiple bolts, and the contact surface between the pad 8 and the fixed wheel 9 is large, making it less prone to loosening. The fixed wheel 9 is positioned above the moving wheel 10. When processing buckwheat, the buckwheat falls into the hulling machine from above the central circular hole of the fixed wheel sleeve 3.

[0023] The outer cylinder 7 is welded to the base plate 12, which has a material leakage hole. The material outlet 22 is welded and fixed below the material leakage hole. A bearing seat 13 is provided at the lower center of the base plate 12. A pressure cap 1 20 and a pressure cap 2 21 are provided above and below the bearing seat 13. A rotating shaft 18 is provided in the bearing seat 13. The rotating shaft 18 is connected to the bearing seat 13 through bearings 1 14, 2 15, pressure caps 1 20 and 2 21, and rotates smoothly.

[0024] A drive wheel 10 is provided on the upper part of the rotating shaft 18, and a sealing cover 19 is provided below the drive wheel 10. The drive wheel 10 and the sealing cover 19 are fixed to the rotating shaft 18 by two set nuts 11 and washers 17. A pulley 16 is provided at the lower part of the rotating shaft 18.

[0025] When processing buckwheat of different particle sizes, the horizontal gap between the fixed wheel 9 and the moving wheel 10 needs to be adjusted. First, loosen the locking nut 4. Depending on the particle size, rotate the adjusting handle 1, which is connected to the upper cover 6 via threads. One full rotation of the adjusting handle 1 raises or lowers the fixed wheel 9 by one thread pitch. By observing the angle rotated by the adjusting handle 1 using the scale 5 fixed on the upper cover 6, the distance the fixed wheel 9 has risen or fallen can be accurately calculated. When the ratio of buckwheat grains to buckwheat hulls in the material discharged from the huller's outlet 22 is appropriate, tighten the locking nut 4 to complete the adjustment of the horizontal gap between the fixed wheel 9 and the moving wheel 10.

[0026] After the external motor is powered on, it drives the pulley 16 to rotate at high speed via a belt, which in turn drives the rotating shaft 18 and the moving wheel 10 to rotate at high speed. The buckwheat enters the hulling machine through the central hole of the fixed wheel sleeve 3 and reaches the cavity between the fixed wheel 9 and the moving wheel 10. Due to the shape of the fixed wheel 9, this cavity is frustoconical. Under the action of centrifugal force, the buckwheat at the center of the frustum pushes the buckwheat at the edge of the frustum to move outwards. When the buckwheat passes through the horizontal gap between the fixed wheel 9 and the moving wheel 10, it is subjected to mutual crushing and rolling by the stationary fixed wheel 9 and the high-speed rotating moving wheel 10, and the buckwheat husk is peeled off. The hulled material is discharged from the discharge port 22 of the hulling machine and enters the next process.

[0027] The above technical solutions aim to improve the operational stability of the shelling machine. At the same time, they increase production efficiency and capacity.

[0028] 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.
