Description

Technical Field

[0001] This utility model relates to the technical field of grain cleaning equipment, and in particular to a fully automatic grain cleaning machine. Background Technology

[0002] A grain impurity remover is a mechanical device specifically designed to remove various impurities from grains. Its main purpose is to improve the purity and quality of grains, ensuring the safety of subsequent processing and consumption.

[0003] Existing grain cleaning machines typically require the grain to be collected before cleaning. However, these machines lack drying capabilities. During the grain accumulation process, moisture may appear on the surface of the grain, requiring separate drying after cleaning, which increases the complexity and time cost of operation.

[0004] To address the aforementioned issues, there is a need for a fully automatic grain cleaning machine capable of drying grains. Utility Model Content

[0005] In order to overcome the shortcomings of existing grain impurity removal machines that do not have a drying function, this utility model provides a fully automatic grain impurity removal machine.

[0006] The technical solution of this utility model is as follows: a fully automatic grain impurity removal machine, comprising a shell, a feeding frame, a first fixed frame, a second fixed frame, shock-absorbing springs, a vibrating motor, a vibrating frame, a screen, and a fan. The first fixed frame and the second fixed frame are installed on the inner wall of the shell. Shock-absorbing springs are symmetrically installed on both the first and second fixed frames. Vibrating motors are installed on both the first and second fixed frames. The vibrating frame is connected between the upper parts of the four shock-absorbing springs. The vibrating frame is fixedly connected to the vibrating motor. A sliding groove is opened on the vibrating frame, and a screen is slidably connected in the sliding groove. A fan is installed at the bottom of the first fixed frame. The machine also includes a connecting frame, a belt conveyor, a dryer, a first motor, a scraper, a lead screw, and a guide rod. The feeding frame is connected to the shell. The connecting frame is connected to the left side of the shell. The belt conveyor is installed at the bottom of the shell. The dryer is installed at the bottom of the second fixed frame. The first motor is installed on the right side of the dryer. The output shaft of the first motor is connected to the lead screw. The guide rod is connected to the right side of the dryer. A scraper is slidably connected between the guide rod and the lead screw.

[0007] Furthermore, it also includes a second motor and a baffle. The second motor is installed on the top of the housing, and the output shaft of the second motor passes through the feed frame and is connected to the baffle.

[0008] Furthermore, it also includes a collection box, with the collection box placed inside the connecting box.

[0009] Furthermore, it also includes a pull plate, which is connected to the front side of the screen.

[0010] Furthermore, the scraper is V-shaped.

[0011] The beneficial effects of this utility model are as follows: by adjusting the scraper, grains of different sizes can be spread out to different degrees, and then the grains can be dried by the dryer to remove surface moisture, thereby preventing the grains from generating excess moisture during the stacking process.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Example: A fully automatic grain impurity removal machine, such as Figures 1-5As shown, the device includes a housing 1, a feed frame 2, a first fixed frame 3, a second fixed frame 301, shock-absorbing springs 302, a vibrating motor 303, a vibrating frame 4, a screen 5, a pull plate 6, a fan 7, a connecting frame 8, a collecting frame 801, a belt conveyor 9, a dryer 10, a first motor 11, a scraper 12, a lead screw 13, a guide rod 1301, a second motor 14, and a baffle 15. The feed frame 2 is connected to the housing 1. The first fixed frame 3 and the second fixed frame 301 are installed on the inner wall of the housing 1. Shock-absorbing springs 302 are symmetrically installed on both the first fixed frame 3 and the second fixed frame 301. Vibrating motors 303 are installed on both the first fixed frame 3 and the second fixed frame 301. A vibrating frame 4 is connected between the upper parts of the four shock-absorbing springs 302. The vibrating frame 4 is fixedly connected to the vibrating motors 303. A sliding groove 401 is provided on the vibrating frame 4. A screen 5 is slidably connected inside the chute 401. A pull plate 6 is connected to the front side of the screen 5. A fan 7 is installed at the bottom of the first fixed frame 3. A connecting frame 8 is connected to the left side of the outer shell 1. A collection frame 801 is placed inside the connecting frame 8 to collect grains. A belt conveyor 9 is installed at the bottom inside the outer shell 1 to transport grains. A dryer 10 is installed at the bottom of the second fixed frame 301 to dry the grains. A first motor 11 is installed on the right side of the dryer 10. A lead screw 13 is connected to the output shaft of the first motor 11. A guide rod 1301 is connected to the right side of the dryer 10. A scraper 12 is slidably connected between the guide rod 1301 and the lead screw 13. The scraper 12 is V-shaped and can adjust the height of the grains passing through. A second motor 14 is installed at the top of the outer shell 1. The output shaft of the second motor 14 passes through the feed frame 2 and is connected to a baffle 15 to adjust the feeding speed.

[0020] When this device is needed to remove impurities from grains, the user first places a screen 5 of appropriate size into the groove 401 of the vibrating frame, and then starts the vibrating motor 303 on the first fixed frame 3 and the second fixed frame 301. The vibrating motor 303 rotates and drives the vibrating frame 4 to vibrate on the shock-absorbing spring 302. Then, the dryer 10, the belt conveyor 9 and the first motor 11 are turned on. The output shaft of the first motor 11 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the scraper 12 to move upward along the guide rod 1301. Once the scraper 12 has moved to the appropriate position, the second motor 14 is turned off and then restarted. The rotation of the output shaft of the second motor 14 will drive the baffle 15 to rotate. After the baffle 15 is rotated to the appropriate position, the grain can be quantitatively fed. Then the second motor 14 is turned off again. The user can then pour the grain into the feed frame 2. The grain falls from the feed frame 2 onto the screen 5 on the first fixed frame 3. The screen 5 vibrates and removes heavier objects from the grain. The removed impurities will then be discharged from the first fixed frame 3. Grains fall from the fixed frame 3, and then from the screen 5 on the first fixed frame 3 to the screen 5 on the second fixed frame 301. During the falling process, the fan 7 blows away lighter impurities in the material, which will fall into the connecting frame 8 and then into the collection frame 801. The screen 5 on the second fixed frame 301 will perform a second fine sieving of the grains, and the sieved impurities will fall from the second fixed frame 301. Then, the grains will fall from the screen 5 on the second fixed frame 301 onto the belt conveyor 9. The belt conveyor 9 will transport the grains to the left. During the grain transport process, the scraper 12 will block the grains, so that only one layer of grains is transported to the left at a time. During the grain transport process, the dryer 10 is started. When the grains are transported to a certain distance, the dryer 10 will dry the grains on the belt conveyor 9 to prevent excessive moisture on the grains. After the grains are dried, they will be transported out of the outer casing 1 by the belt conveyor 9 for fully automatic impurity removal.

[0021] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
