Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically a grain separator with a built-in dust separation structure. Background Technology

[0002] The rice-brown rice separator is a type of grain and oil machinery. It is mainly used in the rice processing process to initially separate the paddy rice and brown rice in the harvested rice-brown rice mixture, so as to facilitate further processing. During the separation process, the separator shakes the mixture to make it enter different channels.

[0003] The patent publication number “CN220239277U” discloses a rice grain separator. The separator body includes a frame and a separation plate. The separation plate is installed inside the frame. Motion grooves are opened on the side walls of the frame, and sliding rods are slidably connected to the side walls of the two motion grooves.

[0004] As shown in the above technology, existing grain separators distribute grains on a separating plate and separate them by vibration. However, since the grains contain dust, this dust will be stirred up during vibration. If the dust is not treated, it will enter the subsequent processing process along with the grains.

[0016] 1. This grain separator with a built-in dust separation structure includes multiple suction ports located on the back of the protective box via a dust removal component. Multiple dust hoods are inserted into the suction ports, and the dust hoods are connected to the collection box via flexible hoses. An exhaust vent is located on the right side of the collection box.

[0024] 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.

[0025] Please see Figures 1-5 The scourt separator with a built-in dust separation structure offers two technical solutions:

[0026] The first embodiment includes a support frame 1, a protective box 2, and a vibration mechanism 3. A dust removal mechanism for dust removal is located at the rear of the protective box 2. The dust removal mechanism includes:

[0027] The dust removal assembly 4 includes a collection box 41, multiple dust suction hoods 43, and an exhaust fan 47. The exhaust fan 47 draws in the dust generated in the protective box 2, and the collected dust enters the collection box 41. The dust collected in the collection box 41 can be quickly discharged. The dust removal assembly 4 also includes multiple suction ports 42 located on the back of the protective box 2. Multiple dust suction hoods 43 are inserted into the multiple suction ports 42. The dust suction hoods 43 and the collection box 41 are connected by flexible hoses 44. An exhaust port 45 is located on the right side of the collection box 41. A filter plate 46 is placed inside the 45. The exhaust fan 47 is fixedly connected to the back of the support frame 1, and the exhaust pipe of the exhaust fan 47 is fixedly connected to the exhaust port 45. A protective plate 48 is rotatably connected between the left and right sides of the inner wall of the collection box 41. The upper side of the protective plate 48 rotates with the inner wall of the collection box 41, and the lower side of the protective plate 48 is fixed to the collection box 41 by bolts. A through hole is opened inside the protective plate 48, and a transparent plate 49 is inlaid in the through hole. The dust collection in the collection box 41 can be observed through the transparent plate 49. A handle 410 is fixedly connected to the back of the protective plate 48.

[0028] When separating grains, the dust removal component 4 sucks away the dust that is raised, thereby avoiding the problem of dust being raised and the grains carrying dust. The dust that is sucked away enters the collection box 41, and the protective plate 48 can be opened to process the dust collected in the collection box 41, thereby improving the practicality of the device when in use.

[0029] The second embodiment differs from the first embodiment mainly in that: the mounting component 5 is used to install multiple vacuum hoods 43 onto the protective box 2, and the mounting component 5 can complete the installation and removal of the vacuum hoods 43 by rotation. The mounting component 5 has a symmetrical structure and includes two fixed seats 51, one above the other. A rotating rod 52 is rotatably connected between the two fixed seats 51, and multiple pressure blocks 53 are fixedly connected at equal intervals on the surface of the rotating rod 52. A handle 54 is fixedly connected to the end of the rotating rod 52 above the fixed seat 51. The left side of the vacuum hood 43... Fixed blocks 55 are fixedly connected to both sides. A limiting wheel 56 is fixedly connected to the surface of the rotating rod 52 above the fixed seat 51. The surface of the limiting wheel 56 has multiple limiting teeth arranged at equal intervals. A fixed rod 57 is fixedly connected to the top of the protective box 2. A limiting rod 58 is rotatably connected to the surface of the fixed rod 57. The limiting rod 58 can prevent the limiting wheel 56 from reversing. A torsion spring 59 is sleeved on the surface of the fixed rod 57 inside the limiting rod 58. One end of the torsion spring 59 is fixedly connected to the surface of the fixed rod 57, and the other end of the torsion spring 59 is fixedly connected to the limiting rod 58.

[0030] The dust collection hood 43 in the dust collection assembly 4 is installed with the protective box 2 through the installation component 5, which makes it easy to disassemble the dust collection hood 43 and thus easy to check the internal condition of the dust collection hood 43, and to handle any blockages.

[0031] When installing the dust cover 43, insert the dust cover 43 into the suction port 42 and rotate the handle 54. The rotation of the handle 54 drives the pressure block 53 to rotate via the rotating rod 52. The pressure block 53 rotates and presses against the fixing block 55, thereby pressing and fixing the position of the dust cover 43. During the rotation of the rotating rod 52, the limiting wheel 56 rotates. The limiting wheel 56 rotates and contacts the limiting rod 58, thereby pushing the limiting rod 58 to rotate. After the limiting wheel 56 stops rotating, under the action of the torsion spring 59, the end of the limiting rod 58 enters the gap between the limiting teeth of the limiting wheel 56, thereby preventing the limiting wheel 56 from reversing. In use, start the vibration mechanism 3 to separate the grains, and at the same time start... The exhaust fan 47 is activated, generating suction. Dust generated during separation is sucked into the dust hood 43 through the suction port 42. The dust enters the collection box 41 through the hose 44. The dust collection in the collection box 41 can be observed through the transparent plate 49. When it is necessary to discharge the dust, loosen the bolt and rotate the protective plate 48 to open it, allowing the dust to be discharged. When it is necessary to check the inside of the dust hood 43, press the limit rod 58. The rotating rod 52 can then rotate freely. By rotating the rotating rod 52 through the handle 54, the pressure block 53 is moved away from the fixed block 55, allowing the dust hood 43 to be pulled out from the suction port 42.
