Description
Technical Field
[0001] The utility model relates to the technical field of paddy production, in particular to a drum separator for paddy production. Background Art
[0002] Paddy refers to the seeds without the husk removed. Botanically, it belongs to the common cultivated rice subgenus in the genus Oryza of the Gramineae family, and there are 22 types of paddy recognized by humans. However, the only type used for bulk trade is the common type of paddy. China is one of the countries with the longest history of rice cultivation and the richest genetic resources of rice. During the production and processing of paddy, a screening machine is needed, such as a paddy drum separator, which is mostly used for screening and processing paddy.
[0003] Currently, when screening paddy, a screening machine is always used. The traditional screening machine can only separate weeds and paddy. After separating weeds and paddy, because the sizes of paddy are different, it is impossible to accurately classify paddy of different sizes. As a result, after separating impurities, it is necessary to classify paddy of different sizes again. Therefore, a drum separator for paddy production is proposed to solve the above problems. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a drum separator for paddy production to solve the problems put forward in the above background art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A drum separator for paddy production includes a bottom plate. A fixed box is fixedly installed on the top side of the bottom plate. A separation drum is arranged on the fixed box through a moving component. An inlet is arranged on the top side of the separation drum. A connecting seat is fixedly installed on one side of the separation drum. Two long holes are respectively opened on both sides of the separation drum, and both long holes communicate with the separation drum. A first filter plate and a second filter plate are respectively arranged in the separation drum. The first filter plate and the second filter plate are respectively located on one side of the two long holes. A first discharge plate and a second discharge plate are respectively fixedly installed on one side of the separation drum. The first discharge plate and the second discharge plate are respectively located on one side of the two long holes, and the first discharge plate is located above the second discharge plate. A collection box is placed on the top side of the bottom plate. A baffle is fixedly installed on the inner wall of the collection box. The collection box is divided into two areas by the baffle. The second discharge plate faces the area close to the fixed box, and the first discharge plate faces the other area. An installation plate is fixedly installed on the top side of the bottom plate. A rotating component and a linkage component are respectively arranged on one side of the installation plate.
[0007] Preferably, the moving component includes two guide rods fixedly installed on the inner wall of the fixed box. A set of first sliders and a set of second sliders are respectively slidably arranged on the two guide rods. The number of each set of first sliders and second sliders is two. The top sides of each set of first sliders and second sliders are inclined. And the height of the two second sliders is higher than that of the two first sliders. The top sides of the two first sliders and the two second sliders are fixedly connected to the bottom side of the separation drum.
[0008] Preferably, the rotating component includes a side plate fixedly installed on one side of the mounting plate. A motor is fixedly installed on one side of the side plate. The output end of the motor rotatably penetrates the side plate and is fixedly sleeved with a second pulley.
[0009] Preferably, the linkage component includes a fixed column fixedly installed on one side of the mounting plate. A first pulley is movably sleeved on the outer side of the fixed column. The same belt is arranged between the first pulley and the second pulley.
[0010] Preferably, a connecting column is fixedly installed on one side of the first pulley. A linkage rod is movably sleeved on the outer side of the connecting column. The other end of the linkage rod is movably sleeved in the connecting seat.
[0011] Preferably, a collection box is placed on the top side of the bottom plate. One side of the collection box is attached to one side of the fixed box. A third discharge plate is fixedly installed on one side inner wall of the fixed box. The third discharge plate faces the collection box.
[0012] Preferably, a guide plate is fixedly installed on the bottom side of the separation drum. The two sides of the guide plate are inclined. The guide plate faces the third discharge plate.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this rice production drum selection machine, because the top sides of the first sliders and the second sliders are both inclined, the separation drum is also installed in an inclined state on the first sliders and the second sliders. Therefore, when the linkage rod drives the separation drum to move back and forth, the weeds and other impurities on the first filter plate will move towards the first discharge plate along the inertia, and thus will flow towards a region of the collection box along the first discharge plate. And the rice with larger volume will move towards the second discharge plate because the separation drum is inclined, and then will flow towards another region of the collection box along the second discharge plate. It is convenient to effectively separate the rice mixed with weeds, and at the same time, it can also separate the rice with different volumes.
[0014] The driving motor drives the second pulley to rotate. When the second pulley rotates, it drives the first pulley arranged at the other end of the belt to rotate. When the first pulley rotates, the connecting column is synchronously driven to rotate. Since one end of the linkage rod is movably sleeved on the connecting column and the other end of the linkage rod is movably sleeved in the connecting seat, when the connecting column reciprocally rotates, the linkage rod pulls the connecting seat back and forth to move, so that the separation drum moves back and forth, capable of shaking the rice inside, facilitating better separation of the rice mixed with weeds, and also capable of separating rice with different volumes and sizes.

Detailed Description of the Preferred Embodiments
[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Refer to Figures 1-4, A drum separator for paddy production, comprising a bottom plate 1. A fixed box 2 is fixedly installed on the top side of the bottom plate 1. A separation drum 6 is arranged on the fixed box 2 through a moving component. An inlet 8 is arranged on the top side of the separation drum 6. A connecting seat 23 is fixedly installed on one side of the separation drum 6. Two long holes are respectively opened on both sides of the separation drum 6, and both long holes communicate with the separation drum 6. A first filter plate 9 and a second filter plate 10 are respectively arranged inside the separation drum 6. The first filter plate 9 and the second filter plate 10 are respectively located on one side of the two long holes. A first discharge plate 11 and a second discharge plate 12 are respectively fixedly installed on one side of the separation drum 6. The first discharge plate 11 and the second discharge plate 12 are respectively located on one side of the two long holes, and the first discharge plate 11 is located above the second discharge plate 12. A collection box 14 is placed on the top side of the bottom plate 1. A baffle 15 is fixedly installed on the inner wall of the collection box 14. The collection box 14 is divided into two areas by the baffle 15. The second discharge plate 12 faces the area close to the fixed box 2, and the first discharge plate 11 faces the other area. An installation plate 17 is fixedly installed on the top side of the bottom plate 1. A rotating component and a linkage component are respectively arranged on one side of the installation plate 17. By providing the first filter plate 9, some paddy with larger and smaller volumes will fall onto the second filter plate 10 through the round holes opened on the first filter plate 9, while some impurities such as weeds will remain on the first filter plate 9. And because the separation drum 6 is fixedly installed on the first slider 4 and the second slider 5, and the top sides of the first slider 4 and the second slider 5 are both inclined, the separation drum 6 is also installed in an inclined state on the first slider 4 and the second slider 5. When the linkage rod 22 drives the separation drum 6 to move back and forth, the weeds and other impurities on the first filter plate 9 will move towards the first discharge plate 11 along the inertia, and thus will flow into one area of the collection box 14 along the first discharge plate 11. And because the radius of the round holes opened on the second filter plate 10 is smaller than that of the round holes opened on the first filter plate 9, some paddy with smaller volumes will fall onto the third discharge plate 13 along the second filter plate 10 and then flow into the collection box 16 for storage, while the paddy with larger volumes will move towards the second discharge plate 12 because the separation drum 6 is inclined, and then will flow into the other area of the collection box 14 along the second discharge plate 12. And by providing the baffle 15, it can also prevent the paddy with larger volumes from being shaken into the area for placing weeds and other impurities when the separation drum 6 shakes back and forth to discharge materials.
[0022] Specifically, the moving component includes two guide rods 3 fixedly installed on the inner wall of the fixed box 2. A set of first sliders 4 and a set of second sliders 5 are respectively slidably arranged on the two guide rods 3. The number of each set of first sliders 4 and second sliders 5 is two. The top sides of each set of first sliders 4 and second sliders 5 are inclined. And the height of the two second sliders 5 is higher than that of the two first sliders 4. The top sides of the two first sliders 4 and the two second sliders 5 are fixedly connected to the bottom side of the separation drum 6. By setting one first slider 4 and a set of second sliders 5, when the separation drum 6 moves back and forth, it will synchronously drive the first sliders 4 and the second sliders 5 to slide on the two guide rods 3, which can play a guiding and supporting role during movement. And because the top sides of the first sliders 4 and the second sliders 5 are inclined, the separation drum 6 is also inclined during installation, so as to better shake out weeds and some larger grains of rice from the separation drum 6, avoiding that too much accumulation will cause the filtering effect of the first filter plate 9 and the second filter plate 10 to deteriorate.
[0023] Specifically, the rotating component includes a side plate 18 fixedly installed on one side of the mounting plate 17. A motor 24 is fixedly installed on one side of the side plate 18. The output end of the motor 24 rotates through the side plate 18 and is fixedly sleeved with a second belt pulley 25. The linkage component includes a fixed column 19 fixedly installed on one side of the mounting plate 17. A first belt pulley 20 is movably sleeved on the outer side of the fixed column 19. A same belt 26 is arranged between the first belt pulley 20 and the second belt pulley 25. A connecting column 21 is fixedly installed on one side of the first belt pulley 20. A linkage rod 22 is movably sleeved on the outer side of the connecting column 21. The other end of the linkage rod 22 is movably sleeved in the connecting seat 23. By starting the motor 24 to drive the second belt pulley 25 to rotate, when the second belt pulley 25 rotates, it drives the first belt pulley 20 arranged at the other end of the belt 26 to rotate. When the first belt pulley 20 rotates, it synchronously drives the connecting column 21 to rotate. And because one end of the linkage rod 22 is movably sleeved on the connecting column 21, and the other end of the linkage rod 22 is movably sleeved in the connecting seat 23, when the connecting column 21 rotates back and forth, the linkage rod 22 pulls the connecting seat 23 to move back and forth, so that the separation drum 6 moves back and forth, so as to shake the rice inside, which is convenient for better separating the rice mixed with weeds.
[0024] Specifically, a collection box 16 is placed on the top side of the bottom plate 1. One side of the collection box 16 is in contact with one side of the fixed box 2. A third discharge plate 13 is fixedly installed on the inner wall of one side of the fixed box 2. The third discharge plate 13 faces the collection box 16. A guide plate 7 is fixedly installed on the bottom side of the separation drum 6. Both sides of the guide plate 7 are inclined. The guide plate 7 faces the third discharge plate 13. By providing the guide plate 7, it can be avoided that the paddy rice splashes when it falls onto the third discharge plate 13. And by providing the collection box 16, after the paddy rice is separated, it will flow along the third discharge plate 13 into the collection box 16 for storage, which is convenient for subsequent unified processing.
[0025] This drum separator for paddy rice production is connected to the 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.
[0026] When in use: When it is necessary to screen paddy rice mixed with impurities such as weeds, the paddy rice is put into the separation drum 6 from the feed inlet 8. Then the motor 24 is started to drive the second belt pulley 25 to rotate. When the second belt pulley 25 rotates, it drives the first belt pulley 20 provided at the other end of the belt 26 to rotate. When the first belt pulley 20 rotates, it synchronously drives the connecting column 21 to rotate. And because one end of the linkage rod 22 is movably sleeved on the connecting column 21, and the other end of the linkage rod 22 is movably sleeved in the connecting seat 23, so when the connecting column 21 reciprocates, the linkage rod 22 pulls the connecting seat 23 back and forth to move, so that the separation drum 6 moves back and forth, so as to shake the paddy rice inside. And by providing the first filter plate 9, some paddy rice with larger and smaller volumes will fall onto the second filter plate 10 through the round holes opened on the first filter plate 9, while some impurities such as weeds will remain on the first filter plate 9. And because the separation drum 6 is fixedly installed on the first slider 4 and the second slider 5, and the top sides of the first slider 4 and the second slider 5 are both inclined, so the separation drum 6 is also installed in an inclined state on the first slider 4 and the second slider 5. When the linkage rod 22 drives the separation drum 6 to move back and forth, the weeds and other impurities on the first filter plate 9 will move towards the first discharge plate 11 along the inertia, and then will flow along the first discharge plate 11 into an area of the collection box 14. And because the radius of the round holes opened on the second filter plate 10 is smaller than that of the round holes opened on the first filter plate 9, so some paddy rice with smaller volumes will fall onto the third discharge plate 13 along the second filter plate 10, and then flow into the collection box 16 for storage. And the paddy rice with larger volumes will move towards the second discharge plate 12 because the separation drum 6 is inclined, and then will flow along the second discharge plate 12 into another area of the collection box 14. And by providing the baffle 15, it can also be avoided that when the separation drum 6 shakes back and forth to discharge materials, the paddy rice with larger volumes is shaken into the area where weeds and other impurities are placed.
