Description

Technical Field

[0001] This utility model belongs to the field of grain processing technology, specifically a grain processing anti-accumulation and impurity removal device. Background Technology

[0002] In the grain processing industry, impurity removal from grains such as wheat is a crucial step in ensuring product quality. In actual production, wheat harvested from the field often contains various impurities, such as straw, stones, clods of soil, and particles of different sizes. These impurities not only affect the purity of the grain but can also damage subsequent processing equipment, reducing production efficiency and product quality. Therefore, effective impurity removal is essential before wheat enters deep processing.

[0003] Currently available grain processing and impurity removal devices have significant shortcomings when processing wheat. They lack effective means to break up piled-up wheat. When wheat enters the equipment, it tends to clump together due to the characteristics of wheat itself and the limitations of the equipment structure. Moreover, the impurities inside the piled-up wheat are difficult to fully expose, making it impossible to fully separate the particle impurities from the wheat. This reduces the impurity removal effect and affects the efficiency and quality of subsequent processing. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model proposes a grain processing anti-accumulation and impurity removal device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A grain processing anti-accumulation and impurity removal device includes a drum mounted above a support frame. A second servo motor is mounted on the drum. The output end of the second servo motor is connected to a stirring shaft via a gear set. The stirring shaft is equipped with stirring blades for breaking up wheat inside the drum. Each end of the stirring shaft is provided with a sleeve column that penetrates the drum and is fitted onto the outside of the rotating shaft. A counterweight ball is provided on the outer wall of the sleeve column.

[0007] As a further preferred embodiment of this technical solution: a sliding shaft is slidably connected to the support frame, a bearing is provided at the top of the sliding shaft, and a rotating shaft is rotatably connected inside the bearing, the rotating shaft being fixedly connected to the roller.

[0008] As a further preferred embodiment of this technical solution: a No. 1 screen is hinged to the roller, and a locking device is provided between the roller and the No. 1 screen.

[0009] As a further preferred embodiment of this technical solution: a baffle is provided on the sliding shaft, and a spring is sleeved on the outer side of the baffle and arranged between the support frame and the baffle.

[0010] As a further preferred embodiment of this technical solution: a connecting frame is provided on the outer wall of the sliding shaft, a first servo motor is provided on the connecting frame, a worm is provided at the output end of the first servo motor, the worm is meshed with a worm wheel, and the worm wheel is fixedly connected to the rotating shaft.

[0011] As a further preferred embodiment of this technical solution: the support frame is also provided with a second screen arranged at an incline, and a baffle for preventing wheat from rolling off is provided on the side of the second screen, and an ultrasonic transmitter is provided on the baffle.

[0012] As a further preferred embodiment of this technical solution: a protective shell is provided on the outer side of the gear set to prevent wheat from entering the gaps of the gear set.

[0013] As a further preferred embodiment of this technical solution: a waste bin is provided below the second screen, and a collection bin is provided below the end of the second screen.

[0014] As a further preferred embodiment of this technical solution: the aperture of the second screen is smaller than that of normal wheat, while the aperture of the first screen is larger than that of normal wheat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the first servo motor drives the drum to rotate. After the first screen is inverted, the second servo motor drives the stirring shaft and stirring blades to rotate, effectively breaking up the wheat accumulated in the drum and exposing the impurities. At the same time, the counterweight ball on the sleeve rotates with the stirring shaft, and the spring makes the drum shake up and down. This not only accelerates the separation of large particles of impurities from the wheat through stirring, but also prevents the wheat from accumulating on the first screen and affecting the screening, significantly improving the initial impurity removal rate and effect.

[0017] 2. In this utility model, wheat is shaken from the drum onto the inclined No. 2 screen. The ultrasonic transmitter causes the No. 2 screen to vibrate, causing the wheat to flow into the collection box. Because the aperture of the No. 2 screen is smaller than that of normal wheat, fine impurities pass through the screen holes and fall into the waste box, achieving secondary fine impurity removal, further removing fine impurities from the wheat, while ensuring smooth collection of wheat, improving the impurity removal effect and product quality of grain processing.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1:

[0025] Please see Figures 1-4 This application provides a grain processing anti-accumulation and impurity removal device, including a drum 6 installed above a support frame 1. A second servo motor 12 is installed on the drum 6. The output end of the second servo motor 12 is connected to a stirring shaft 15 through a gear set 13. The stirring shaft 15 is provided with stirring blades 16 for breaking up wheat inside the drum 6. A sleeve 24 is provided at each end of the stirring shaft 15, which is arranged through the drum 6. The sleeve 24 is sleeved on the outside of the rotating shaft 4. A counterweight ball 5 is provided on the outer wall of the sleeve 24.

[0026] The support frame 1 is also slidably connected to a sliding shaft 2. A bearing 3 is provided on the top of the sliding shaft 2, and a rotating shaft 4 is rotatably connected inside the bearing 3. The rotating shaft 4 is fixedly connected to the roller 6.

[0027] A first screen 7 is hinged to the roller 6, and a locking device is provided between the roller 6 and the first screen 7. This is an existing product, and its purpose is to ensure that the first screen 7 will not separate from the roller 6 after the roller 6 has rotated 180 degrees.

[0028] A baffle plate 23 is provided on the sliding shaft 2, and a spring 22 is sleeved on the outer side of the baffle plate 23 and arranged between the support frame 1 and the baffle plate 23.

[0029] A connecting frame 8 is provided on the outer wall of the sliding shaft 2. A first servo motor 9 is provided on the connecting frame 8. A worm gear 10 is provided at the output end of the first servo motor 9. The worm gear 10 is meshed with a worm wheel 11, and the worm wheel 11 is fixedly connected to the rotating shaft 4.

[0030] A protective shell 14 is provided on the outside of the gear set 13 to prevent wheat from entering the gap of the gear set 13 and affecting the transmission of the gear set 13.

[0031] Specifically, by opening the first screen 7, wheat is placed inside the drum 6. Then, the first screen 7 is closed onto the drum 6 and locked in place. Next, the first servo motor 9 is started, and through the transmission of the worm gear 10 and worm wheel 11, the drum 6 is rotated 180 degrees, effectively rotating the first screen 7 to the bottom of the drum 6. Then, by starting the second servo motor 12, and through the transmission of the gear set 13, the stirring shaft 15 drives the stirring blades 16 to break up the piled-up wheat, fully exposing impurities in the wheat and removing them along with the wheat. The wheat particles fall through the aperture of the first screen 7, while larger impurities remain inside the drum 6. The sleeve 24 rotates with the stirring shaft 15. Due to the action of the counterweight ball 5, the sliding shaft 2 slides downward relative to the support frame 1. With the cooperation of the spring 22, the drum 6 shakes up and down continuously. On the one hand, the stirring blades 16 break up the piled-up wheat, increasing the rate of initial filtration of larger impurities. On the other hand, the up and down shaking of the drum 6 can prevent the wheat from accumulating inside the first screen 7 and failing to be properly screened.

[0032] Example 2:

[0033] Based on Embodiment 1, the support frame 1 is also provided with a second screen 19 arranged at an angle. A baffle 18 for preventing wheat from rolling off is provided on the side of the second screen 19. An ultrasonic transmitter 17 is provided on the baffle 18. The ultrasonic transmitter 17 is a prior art technology that can generate vibration through ultrasonic waves. By being electrically connected to an external control device and power supply, the vibration of the second screen 19 is increased.

[0034] A waste bin 20 is provided below the second screen 19, and a collection bin 21 is provided below the end of the second screen 19.

[0035] The aperture of the second screen 19 is smaller than that of normal wheat, while the aperture of the first screen 7 is larger than that of normal wheat.

[0036] Specifically, after the wheat is shaken out of the drum 6, it falls onto the second screen 19 and vibrates with the help of the ultrasonic transmitter 17, making the second screen 19 vibrate. This facilitates the flow of wheat into the collection box 21. At the same time, small impurities pass through the screen holes above the vibrating second screen 19 and fall into the waste box 20, thus completing the removal of impurities from the wheat.

[0037] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
