Description

Technical Field

[0001] This utility model belongs to the field of adjustment mechanism technology, and more specifically, it relates to an inlet adjustment mechanism for millet shelling processing. Background Technology

[0002] Rice, also known as millet or foxtail millet, is generally divided into two categories: glutinous millet and non-glutinous millet. Usually, red and gray millet is glutinous millet, while white, yellow, orange, and brown millet is non-glutinous millet. In the process of making millet, it needs to be hulled, and hulling requires a hulling machine.

[0003] The feed inlet size and structure of the existing millet shelling device are fixed and cannot be adjusted according to the required feeding speed. This results in the material falling in a concentrated manner during the feeding process, which affects the efficiency of millet shelling.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a feeding port adjustment mechanism for millet shelling processing, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a feed inlet adjustment mechanism for millet shelling processing, which is achieved by the following specific technical means:

[0006] A millet shelling processing feed inlet adjustment mechanism includes a feed pipe and a feed inlet at the top of the feed pipe. Multiple sets of baffles are rotatably installed along the circumference of the feed pipe inside the feed inlet. These baffles are fan-shaped and can be joined to form a circle that matches the shape and size of the feed inlet. A conical seat is rotatably mounted on one side of each set of baffles. The bottom end of the conical seat is fixedly connected to the inner wall of the feed inlet via a bracket. A rotating shaft is mounted on the other side of each set of baffles. The other end of each rotating shaft is installed through the outer wall of the feed pipe. A drive bar is mounted on the other end of each rotating shaft. A waist-shaped groove is formed on one side of each drive bar. A drive rod is slidably installed within each waist-shaped groove. A drive ring is mounted on one end of each drive rod. The drive ring is sleeved on the outer wall of the feed pipe, and the drive ring is rotatably connected to the outer wall of the feed pipe.

[0007] Preferably, a base frame is symmetrically installed on the outer wall of the feed pipe, and a pulley is rotatably installed on one side of each of the two base frames. Both sets of pulleys are slidably connected to the inner wall of the drive ring.

[0008] Preferably, the outer wall of the drive ring is equipped with drive teeth for driving the drive ring to rotate. A gear is meshed on one side of the drive teeth. A motor is driven to the bottom end of the gear. A bottom tube is fixedly connected to the bottom side of the motor. The bottom tube is fixedly fitted to the bottom end of the feed pipe.

[0009] Preferably, it also includes a feed hopper, which is a funnel-shaped structure with a large opening at the top and a small opening at the bottom.

[0010] Preferably, the axis of the rotating shaft is perpendicular to the axis of the feed pipe, and both ends of the rotating shaft are rotatably connected to the inner wall of the feed pipe through bearings, so that the baffle can rotate smoothly around the rotating shaft inside the feed pipe.

[0011] Preferably, the multiple baffles are made of stainless steel and have a polished surface.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model has multiple sets of fan-shaped baffles that can be rotatably installed along the circumference of the feed tube at equal angles, and can be spliced ​​together to form a circle that fits the feed inlet. This design allows the size of the feed inlet to be flexibly and precisely adjusted by controlling the rotation angle of the baffles, thereby achieving precise control of the amount of millet fed. At different stages of millet shelling, the feeding speed and amount can be adjusted according to actual needs to ensure shelling effect and production efficiency.

[0014] 2. In this utility model, multiple sets of baffles are connected to a drive bar via a rotating shaft. The waist-shaped groove on the drive bar cooperates with the drive rod, which in turn is connected to the drive ring. When the drive ring rotates, it can stably and synchronously drive multiple sets of baffles to rotate, ensuring that the rotation angle of each baffle is consistent, avoiding uneven opening of the feed inlet, and ensuring the stability and reliability of the feed rate adjustment. The base frame and pulleys are symmetrically installed on the outer wall of the feed pipe. The pulleys are slidably connected to the inner wall of the drive ring. This design reduces the friction between the drive ring and the outer wall of the feed pipe when the drive ring rotates, making the drive ring rotate more smoothly, reducing energy loss and component wear, extending the service life of the adjustment mechanism, and also improving the stability of the entire adjustment process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a feeding port adjustment mechanism for millet shelling processing, including a feeding pipe 1 and a feeding port opened at the top of the feeding pipe 1. Multiple sets of baffles 3 are rotatably installed inside the feeding port along the circumference at equal angles. The multiple sets of baffles 3 are all fan-shaped structures and can be spliced ​​together to form a circle. The circle is adapted to the shape and size of the feeding port. A conical seat 15 is rotatably installed on one side of the multiple sets of baffles 3. The bottom end of the conical seat 15 is fixedly connected to the inner wall of the feeding port through a bracket 16. A rotating shaft 4 is installed on the other side of the multiple sets of baffles 3. The other end of the multiple sets of rotating shafts 4 is installed through the outer wall of the feeding pipe 1. A drive bar 5 is installed on the other end of the multiple sets of rotating shafts 4. A waist-shaped groove 6 is opened on one side of the multiple sets of drive bars 5. A drive rod 7 is slidably installed in the multiple sets of waist-shaped grooves 6. A drive ring 8 is installed on one end of the multiple sets of drive rods 7. The drive ring 8 is sleeved on the outer wall of the feeding pipe 1 and is rotatably connected to the outer wall of the feeding pipe 1.

[0025] The feed pipe 1 has symmetrically mounted base frames 13 on its outer wall. Each of the two sets of base frames 13 has a pulley 14 rotatably mounted on one side. Both sets of pulleys 14 are slidably connected to the inner wall of the drive ring 8. The sliding connection between the pulleys 14 and the inner wall of the drive ring 8 transforms the sliding friction between the drive ring 8 and the feed pipe 1 into rolling friction, greatly reducing friction. This makes the rotation of the drive ring 8 smoother, reduces energy loss, and improves power transmission efficiency. The symmetrically arranged pulleys 14 can provide stable support and guidance for the drive ring 8, preventing the drive ring 8 from shaking or deviating during rotation, and ensuring the stability and reliability of the entire adjustment mechanism.

[0026] The outer wall of the drive ring 8 is equipped with drive teeth 9 for driving the drive ring 8 to rotate. A gear 10 is meshed on one side of the drive teeth 9. A motor 11 is connected to the bottom end of the gear 10. A bottom tube 12 is fixedly connected to the bottom side of the motor 11. The bottom tube 12 is fixedly fitted to the bottom end of the feed pipe 1. The meshing transmission between the drive teeth 9 and the gear 10 can accurately transmit the power of the motor 11 to the drive ring 8, realizing precise control of the rotation angle and speed of the drive ring 8. This helps to accurately adjust the opening size of the feed port to meet different feed volume requirements.

[0027] It also includes a feeding hopper 2, which is a funnel-shaped structure with a large opening at the top and a small opening at the bottom. The larger opening at the top can easily collect and hold a large amount of millet, while the smaller opening at the bottom can guide the millet to the feeding port, preventing the millet from scattering or piling up during the feeding process, thus improving the efficiency and smoothness of feeding.

[0028] The axis of the rotating shaft 4 is perpendicular to the axis of the feed pipe 1, and both ends of the rotating shaft 4 are rotatably connected to the inner wall of the feed pipe 1 through bearings, so that the baffle 3 can rotate smoothly around the rotating shaft 4 inside the feed pipe 1.

[0029] Among them, multiple sets of baffles 3 are made of stainless steel and have been polished.

[0030] The working principle of this embodiment is as follows: After the motor 11 starts, the output power drives the gear 10 to rotate. Since the gear 10 meshes with the drive teeth 9 on the outer wall of the drive ring 8, the rotation of the gear 10 will cause the drive ring 8 to rotate around the outer wall of the feed pipe 1. When the drive ring 8 rotates, the multiple sets of drive rods 7 connected to it will move accordingly. The drive rods 7 slide in the waist-shaped groove 6 of the drive bar 5, thereby driving the drive bar 5 to move. The drive bar 5 is also connected to the rotating shaft 4 installed on the outer wall of the feed pipe 1, which will eventually cause the rotating shaft 4 to rotate, driving the fan-shaped baffle 3 in the feed pipe 1 to rotate around the rotating shaft 4. The multiple sets of baffles 3 can be spliced ​​together to form a circle. By controlling the rotation angle of the baffles 3, the size of the circular opening formed by them can be changed, thereby accurately adjusting the size of the feed inlet and realizing the control of the millet feed amount.

[0031] To ensure stable equipment operation: On the one hand, the base frame 13 and pulley 14 symmetrically installed on the outer wall of the feed pipe 1 play an important role. The pulley 14 is slidably connected to the inner wall of the drive ring 8, which greatly reduces the friction when the drive ring 8 rotates, reduces component wear, and ensures stable rotation of the drive ring 8, making the feed port adjustment process smoother. On the other hand, the special installation method of the rotating shaft 4, with its axis perpendicular to the axis of the feed pipe 1 and its two ends rotatably connected to the inner wall of the feed pipe 1 through bearings, provides stable support for the rotation of the baffle 3, ensuring that the baffle 3 can rotate smoothly in the feed pipe 1, avoiding jamming, and ensuring the stable operation of the entire feed port adjustment mechanism. In addition, multiple sets of baffles 3 made of stainless steel and polished are not only durable, but also reduce the adhesion of millet to the surface of the baffle 3, making it easy to clean and ensuring the continuous and stable operation of the feeding process.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
