Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically to a grain dehulling device. Background Technology

[0002] Grain processing refers to the business activities of transforming raw grains into semi-finished grains or finished grains, or vice versa. In the process of processing some grains with husks, it is necessary to remove the husks. Manual husking is inefficient, so husking equipment is often used to process grains with husks.

[0003] However, existing dehulling devices do not completely separate the grain from the husk during use, and husk residue is easily left in the grain. This makes it difficult to centrally process the dehulled grain husks, and the grain husks are directly discharged from the device and scattered around, affecting subsequent processing and environmental protection.

[0004] Therefore, it is necessary to modify it by using a negative pressure device to extract the grain husk mixture after dehulling, removing the lighter husks to ensure thorough separation of the grain husks, and then collecting and processing the separated grain husks in a centralized manner to facilitate subsequent processing and improve environmental friendliness. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a grain dehulling device that uses a negative pressure device to extract the grain-hull mixture after dehulling, removing the lighter hulls to ensure thorough separation of grain and hulls. It also provides centralized collection and processing of the separated grain hulls, facilitating subsequent processing and improving environmental friendliness. This solution addresses the problems of incomplete hull-grain separation, hull residue in the grain, difficulty in centralized processing of separated grain hulls, and grain hulls scattering everywhere after being discharged from the device, thus affecting subsequent processing and environmental impact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain hulling device, comprising a base plate, a thresher body disposed on the left side of the top of the base plate, a feed hopper connected to the top of the thresher body, a discharge port disposed on the lower right side of the thresher body, a receiving frame disposed on the right side of the top of the base plate and located to the right of the discharge port, an inclined plate fixedly connected inside the receiving frame and located below the discharge port, the inclined plate being inclined to the right, a shell-extraction cover disposed in the center of the receiving frame and located above the inclined plate, a negative pressure pipe connected to the top of the shell-extraction cover, a collection box connected to the top of the negative pressure pipe, an exhaust fan fixedly connected to the right side of the collection box via a support plate, the input end of the exhaust fan being connected to the right side of the collection box, a sealing cleaning door hinged to the front of the collection box via a hinge, a vibration motor fixedly connected to the right side of the top front of the base plate, the output end of the vibration motor being in contact with the front of the receiving frame, and reset buffer mechanisms fixedly connected to the front and back sides of the receiving frame.

[0007] As a preferred embodiment of this utility model, the reset buffer mechanism includes a damping rod fixedly connected to the surface of the receiving frame, a support plate fixedly connected to the end of the damping rod away from the receiving frame, the bottom of the support plate fixedly connected to the top of the base plate, a buffer spring sleeved on the surface of the damping rod, the inner end of the buffer spring fixedly connected to the surface of the receiving frame, and the outer end of the buffer spring fixedly connected to the inner side of the support plate.

[0008] As a preferred embodiment of this utility model, slots located outside the input end of the exhaust fan are fixedly connected to both the upper and lower sides of the right side of the inner wall of the collection box. A protective frame is inserted into the slot, and a filter screen is fixedly connected inside the protective frame.

[0009] As a preferred embodiment of this invention, the output end of the exhaust fan is threadedly connected to a filter cartridge box, and an air filter is provided inside the filter cartridge box.

[0010] As a preferred embodiment of this utility model, T-shaped strips are fixedly connected to the left and right sides of the top of the base plate, and T-shaped grooves that cooperate with the T-shaped strips are opened on the left and right sides of the bottom of the receiving frame. The surface of the T-shaped strips is slidably connected to the inner wall of the T-shaped grooves.

[0011] As a preferred embodiment of this utility model, a vibration damping pad is fixedly connected to the bottom of the base plate, and the surface of the vibration damping pad is provided with anti-slip texture.

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

[0013] 1. This utility model uses the threshing machine body to dehull grain. The discharged outlet contains a mixture of dehulled grain and husk, which falls into a receiving frame. The inclined plate allows the grain mixture to slide naturally within the receiving frame, facilitating subsequent separation operations. A negative pressure device, consisting of a hull extraction hood, negative pressure pipe, collection box, and exhaust fan, utilizes the negative pressure generated by the exhaust fan to extract the lighter grain husks through the hull extraction hood into the collection box, achieving effective separation of grain and husks and preventing husk residue from remaining in the grain. The sealed cleaning door on the front of the collection box facilitates regular cleaning of the collected grain husks, allowing for centralized processing and preventing further contamination. Grain husks are scattered everywhere. The vibrating motor causes the receiving frame to vibrate, which helps the grain slide better off the inclined plate and also allows the grain and husks to separate better during the vibration process, further improving the grain-husk separation effect. The reset and buffer mechanism can buffer and reset during the vibration process, ensuring the stability and service life of the receiving frame. This achieves the effect of using a negative pressure device to extract the grain-husk mixture after dehulling, removing the lighter husks, so that the grain and husks are completely separated, and the grain husks after separation are collected and processed in a centralized manner, which facilitates subsequent processing and improves environmental protection.

[0014] 2. This utility model uses a damping rod, a support plate, and a buffer spring to work together. When the vibrating motor causes the receiving frame to vibrate, the buffer spring can absorb and buffer the vibration energy, while the damping rod can further control the amplitude and frequency of the vibration to prevent the receiving frame from vibrating excessively. At the same time, after the vibration ends, the buffer spring and damping rod can help the receiving frame quickly return to its initial position, ensuring the stability and reliability of the receiving frame during the vibration process and extending its service life.

[0020] 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.

[0021] like Figures 1 to 4 As shown, the present invention provides a grain hulling device, including a base plate 1, a threshing machine body 2 disposed on the top left side of the base plate 1, a feed hopper 3 connected to the top of the threshing machine body 2, a discharge port 4 disposed on the lower right side of the threshing machine, a receiving frame 5 disposed on the right side of the top right side of the base plate 1, located to the right of the discharge port 4, an inclined plate 6 fixedly connected inside the receiving frame 5, located below the discharge port 4, the inclined plate 6 being inclined to the right, and a hulling cover 7 disposed in the center inside the receiving frame 5, located above the inclined plate 6. The top of the shell cover 7 has a negative pressure pipe 8, and the top of the negative pressure pipe 8 is connected to a collection box 9. The right side of the collection box 9 is fixedly connected to an exhaust fan 10 via a support plate. The input end of the exhaust fan 10 is connected to the right side of the collection box 9. The front of the collection box 9 is hinged to a sealing cleaning door 11. The right side of the top front of the bottom plate 1 is fixedly connected to a vibration motor 12. The output end of the vibration motor 12 is in contact with the front of the receiving frame 5. The front and back sides of the receiving frame 5 are fixedly connected to a reset buffer mechanism 13.

[0022] refer to Figure 2 The reset buffer mechanism 13 includes a damping rod 14 fixedly connected to the surface of the receiving frame 5. A support plate 15 is fixedly connected to one end of the damping rod 14 away from the receiving frame 5. The bottom of the support plate 15 is fixedly connected to the top of the base plate 1. A buffer spring 16 is sleeved on the surface of the damping rod 14. The inner end of the buffer spring 16 is fixedly connected to the surface of the receiving frame 5, and the outer end of the buffer spring 16 is fixedly connected to the inner side of the support plate 15.

[0023] As a technical optimization of this utility model, by setting up a damping rod 14, a support plate 15 and a buffer spring 16 to cooperate with each other, when the vibrating motor 12 works to make the receiving frame 5 vibrate, the buffer spring 16 can absorb and buffer the vibration energy, and the damping rod 14 can further control the amplitude and frequency of the vibration to prevent the receiving frame 5 from vibrating excessively. At the same time, after the vibration ends, the buffer spring 16 and the damping rod 14 can help the receiving frame 5 quickly return to its initial position, ensuring the stability and reliability of the receiving frame 5 during the vibration process and extending its service life.

[0024] refer to Figure 4The upper and lower sides of the right side of the inner wall of the collection box 9 are fixedly connected to slots 17 located outside the input end of the exhaust fan 10. A protective frame 18 is inserted into the slot 17, and a filter screen is fixedly connected inside the protective frame 18.

[0025] As a technical optimization of this utility model, the use of the slot 17 and the protective frame 18 makes it convenient to install and remove the filter screen. The filter screen can prevent grain husks from being drawn into the exhaust fan 10, avoid damage to the exhaust fan 10, and play a role in protecting the exhaust fan 10. At the same time, when the filter screen needs to be cleaned or replaced, the protective frame 18 can be pulled out from the slot 17. The operation is convenient and the equipment is easy to maintain.

[0026] refer to Figure 2 The output end of the exhaust fan 10 is threadedly connected to a filter box 19, and an air filter is installed inside the filter box 19.

[0027] As a technical optimization of this utility model, by setting the filter cartridge 19 and the air filter in combination, the exhaust air can be filtered to further remove any small grain husk particles or dust that may remain in the air, purify the exhaust air, improve the air quality of the working environment, and meet environmental protection requirements. Moreover, the filter cartridge 19 is connected to the output end of the exhaust fan 10 by a thread, which makes it easy to disassemble and replace the air filter and facilitates equipment maintenance.

[0028] refer to Figure 1 T-shaped strips 20 are fixedly connected to the top left and right sides of the base plate 1. T-shaped grooves 21 that cooperate with the T-shaped strips 20 are opened on the bottom left and right sides of the receiving frame 5. The surface of the T-shaped strips 20 is slidably connected to the inner wall of the T-shaped grooves 21.

[0029] As a technical optimization of this utility model, by setting T-shaped strips and T-shaped grooves in combination, the receiving frame 5 is slidably connected on the base plate 1. When the vibration motor 12 is working, this sliding connection method can ensure that the receiving frame 5 can vibrate stably along the T-shaped strip, prevent the receiving frame 5 from shifting or shaking too much during vibration, and enhance the stability of the receiving frame 5 during vibration.

[0030] refer to Figure 2 The bottom of the base plate 1 is fixedly connected to a vibration damping pad 22, and the surface of the vibration damping pad 22 is provided with anti-slip texture.

[0031] As a technical optimization of this utility model, by setting the vibration damping pad 22, the impact of the vibration generated by the equipment during operation on the ground can be reduced, and the noise can be reduced. The anti-slip texture on the surface of the vibration damping pad 22 can increase the friction between the base plate 1 and the ground, prevent the equipment from sliding during operation, and improve the stability and safety of the equipment.

[0032] The working principle and usage process of this utility model are as follows: During use, check that all components of the equipment are securely installed, including the thresher body 2, receiving frame 5, exhaust fan 10, and vibrating motor 12. Check that the sealing cleaning door 11 of the collection box 9 is tightly closed, and that the filter screen in the protective frame 18 and the air filter element in the filter element box 19 are correctly installed and undamaged. After confirming that everything is correct, start the thresher body 2, exhaust fan 10, and vibrating motor 12 in sequence. Grain is added to the thresher body 2 through the feeding hopper 3, and the thresher body 2 begins to husk the grain. The threshing machine body 2 is based on existing mature technology, so its working principle will not be described in detail. After threshing, the grain and husk mixture falls onto the inclined plate 6 through the discharge port 4. Under the action of the vibrating motor 12, the grain and husk mixture slides down the inclined plate 6. At the same time, the husk extraction hood 7 draws the grain husk into the collection box 9 under negative pressure. The grain is output from the right side of the receiving frame 5. In subsequent use, the sealed cleaning door 11 of the collection box 9 needs to be opened regularly to clean the collected grain husk. After the filter screen and air filter element have been used for a period of time, they should be cleaned or replaced according to the actual situation.
