Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for a rice mill. Background Art

[0002] Rice milling machine is a kind of mechanical equipment used to process paddy into rice. It is mainly composed of fixed wrench, tightening nut wrench, brush, lower hopper, grinding wheel, wire brush, etc. The mechanical force generated by the mechanical equipment is used to peel and whiten the brown rice. The mechanical equipment used is called rice milling machine. There are three main types of small rice milling machines in my country: separate rice milling machine, rice hulling and milling combined rice milling machine and air jet rice milling machine.

[0003] The Chinese patent with authorization announcement number CN209696993U discloses a rice mill feeding device, including a hopper, a sieve plate, a magnet and a disassembly structure. The hopper is larger at the top and smaller at the bottom. The lower end of the hopper is used to be fixed to the rice mill body and connected to the rice milling chamber. The upper part of the hopper is a square cylinder, and the sieve plate is detachably connected to the square cylinder through the disassembly structure. The sieve plate is horizontally arranged, and sieve holes are evenly arranged on the sieve plate. Magnets are fixed on the nodes between the sieve holes.

[0004] In the prior art, when rice is fed, it is screened through a sieve, but larger impurities such as stones contained in the rice will remain on the surface of the sieve. Over a long period of time, the number of clogged holes gradually increases, resulting in a gradual decrease in the efficiency of screening and feeding. Therefore, the present application provides a rice mill feeding mechanism to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a feeding mechanism for a rice mill to solve the problem proposed in the above background technology that rice is screened through a screen, but impurities such as stones contained in the rice will remain on the surface of the screen, and the clogged through holes will gradually increase over a long period of use, resulting in a gradual decrease in the efficiency of screening and feeding.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A rice milling machine feeding mechanism includes a feeding bin and four mounting brackets. A filter plate is slidably connected to the bottom of the feeding bin. The shape of the filter plate is arc-shaped. A turning mechanism is arranged inside the feeding bin. The turning mechanism includes a reduction motor, a hose, a hot air blower and a mounting seat. One side of the reduction motor is fixedly installed on one side of the feeding bin. The output end of the reduction motor is drivingly connected with a clamping plug. One end of the clamping plug is clamped with a ventilation pipe. A rotating ring is fixedly installed on the outer wall of the ventilation pipe. Hook-shaped turning plates are evenly arranged around the rotating ring. The outer edges of all the turning plates form an annular shape. One end of the ventilation pipe is rotatably connected with a connecting pipe. The outer wall of the rotating ring is in contact with the inner wall of the filter plate. One end of the hose is fixedly installed on one end of the connecting pipe. One side of the hot air blower is fixedly installed on one end of the hose.

[0008] Preferably, one side of the four mounting brackets is fixedly connected to one side of the feeding bin. One side of the filter plate is in contact with one side of the feeding bin.

[0009] Preferably, the outer wall of the clamping plug is rotatably connected to the inner wall of the feeding bin. The outer wall of the connecting pipe is fixedly connected to the inner wall of the feeding bin.

[0010] Preferably, one side of the mounting seat is fixedly installed on one side of the feeding bin. The outer wall of the hot air blower is fixedly installed inside the mounting seat.

[0011] Preferably, the central axis of the ventilation pipe and the central axis of the annular shape formed by the outer edges of all the turning plates are on the same straight line. The inner wall of the ventilation pipe presents a frustum shape with a larger left end and a smaller right end in a horizontal placement.

[0012] Preferably, screening holes for screening are opened at the bottom of the filter plate. Ventilation holes for ventilation are penetrated and opened on the outer wall of the ventilation pipe.

[0013] Preferably, communication holes are penetrated and opened on the outer wall of the rotating ring. The axis of the communication hole and the axis of the ventilation hole are on the same straight line.

[0014] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0015] In the above solution, by setting the rotating ring and the turning plates, the stones stay on the top of the filter plate. Since the inner wall of the filter plate fits the shape of the outer edge of the turning plates, while the turning plates stir and turn the paddy clockwise, every time the curved arc surface of the outer edge of the turning plate passes through the top of the filter plate, it will scrape the top of the filter plate, lifting the stones staying on the top of the filter plate. The stones temporarily stay on the arc surface of the turning plates, avoiding the gradual reduction of the screening efficiency caused by the blockage of the screening holes of the filter plate by impurities.

[0016] By setting up a turning mechanism, the hot air blown by the hot air blower can accelerate the evaporation of moisture in the paddy. The stirring and turning of the turning plate can ensure that the paddy is in full contact with the hot air, achieving uniform drying, avoiding local over-wetness or over-dryness, and preventing the agglomerated paddy containing moisture from failing to sieve and fall through the screening holes of the filter plate.

[0017] By setting up an air pipe, since the inner wall of the air pipe is in the shape of a frustum of a cone, gradually narrowing from left to right, the particles will gradually move towards the right end of the air pipe without falling out of the air pipe. Since the clamping plug and the air pipe are clamped to each other, it is convenient to disassemble the clamping plug and the air pipe to clean out the remaining impurities.

[0029] As Figures 1-4As shown in the figure, an embodiment of the present utility model provides a rice milling machine feeding mechanism, comprising: a feeding bin 1 and four mounting brackets 2. A filter plate 3 is slidably connected to the bottom of the feeding bin 1. The filter plate 3 is in an arc shape. A turning mechanism 4 is arranged inside the feeding bin 1. The turning mechanism 4 includes a reduction motor 41, a hose 46, a hot air blower 47 and a mounting seat 48. One side of the reduction motor 41 is fixedly installed on one side of the feeding bin 1. The output end of the reduction motor 41 is drivingly connected to a clamping plug 42. One end of the clamping plug 42 is clamped with a ventilation pipe 43. A rotating ring 44 is fixedly installed on the outer wall of the ventilation pipe 43. Turning plates in the shape of hooks are evenly arranged around the rotating ring 44. The outer edges of all the turning plates form a circular ring. One end of the ventilation pipe 43 is rotatably connected to a connecting pipe 45. The outer wall of the rotating ring 44 is in contact with the inner wall of the filter plate 3. One end of the hose 46 is fixedly installed on one end of the connecting pipe 45. One side of the hot air blower 47 is fixedly installed on one end of the hose 46. One side of the four mounting brackets 2 is fixedly connected to one side of the feeding bin 1. One side of the filter plate 3 is in contact with one side of the feeding bin 1. The outer wall of the clamping plug 42 is rotatably connected to the inner wall of the feeding bin 1. The outer wall of the connecting pipe 45 is fixedly connected to the inner wall of the feeding bin 1. One side of the mounting seat 48 is fixedly installed on one side of the feeding bin 1. The outer wall of the hot air blower 47 is fixedly installed inside the mounting seat 48. Screening holes for screening are opened at the bottom of the filter plate 3. Ventilation holes for ventilation are penetrated and opened on the outer wall of the ventilation pipe 43.

[0030] When pouring paddy into the interior of the rice milling machine for feeding, the particles of paddy are smaller than those of impurities such as stones. First, fix the feed bin 1 to the top of the rice milling machine through the mounting frame 2, and then pour paddy into the upper opening of the feed bin 1. The upper opening of the feed bin 1 shows a trend of being larger at the top and smaller at the bottom. The larger upper opening allows more paddy to enter the rice milling machine simultaneously, thereby improving the feeding efficiency and the overall processing speed, helping the material to be more evenly distributed when entering the interior of the rice milling machine, avoiding local overload, and ensuring the uniformity and efficiency of the rice milling process. The paddy falls onto the turning plate blades on the outer wall of the rotating ring 44. Start the reduction motor 41 to drive the clamping plug 42, the ventilation pipe 43, and the rotating ring 44 to rotate. During the rotation of the turning plate, the paddy is turned over. At the same time, start the hot air blower 47. The hot air blown by the hot air blower 47 is transmitted to the interior of the connecting pipe 45 through the hose 46, and then enters the interior of the ventilation pipe 43 from the connecting pipe 45 and blows out from the ventilation holes and the communication holes. The diameters of the ventilation holes and the communication holes are smaller than the paddy particles. While the turning plate turns and stirs the paddy, the hot air is evenly blown between the paddy. By setting the turning mechanism 4, the hot air blown by the hot air blower 47 can accelerate the evaporation of moisture in the paddy. The stirring and turning of the turning plate can ensure that the paddy is fully contacted with the hot air, realizing uniform drying, avoiding local over-wetness or over-dryness, and preventing the agglomerated paddy containing moisture from not being screened and dropped from the screening holes of the filter plate 3. By setting the rotating ring 44 and the turning plate, the paddy drops from the screening holes of the filter plate 3, and the stones stay on the top of the filter plate 3. Since the inner wall of the filter plate 3 fits the shape of the outer edge of the turning plate, every time the curved arc surface of the outer edge of the turning plate passes over the top of the filter plate 3 while the rotating ring 44 and the turning plate rotate clockwise to stir and turn the paddy, it will scrape the top of the filter plate 3, scraping up the stones staying on the top of the filter plate 3. The stones temporarily stay on the arc surface of the turning plate, avoiding the screening efficiency from gradually decreasing due to the blockage of the screening holes of the filter plate 3 by impurities. Continuously pour paddy from the top of the feed bin 1 for screening and feeding. After use, pull the filter plate 3 outward from the left side, so that the filter plate 3 slides inside the feed bin 1. Some stones stay on the top of the filter plate 3, and some stones stay on the surface of the turning plate. Start the reduction motor 41 to drive the ventilation pipe 43 and the rotating ring 44 to rotate slowly. During the rotation of the turning plate, the stones attached to the surface gradually fall off and fall out from the bottom of the feed bin 1.

[0031] As Figure 2 and 4 shown, communication holes are penetrated and opened on the outer wall of the rotating ring 44. The axis of the communication holes is on the same straight line as the axis of the ventilation holes. The central axis of the ventilation pipe 43 is on the same straight line as the central axis of the circular ring formed by all the outer edges of the turning plates. The inner wall of the ventilation pipe 43 presents a horizontally placed frustum shape that is larger at the left end and smaller at the right end.

[0032] While using the breather pipe 43 and the turning plates on the outer wall of the rotating ring 44 to stir the paddy, some particles smaller than the ventilation holes and communication holes fall into the interior of the breather pipe 43. Since the inner wall of the breather pipe 43 is frustum-shaped and gradually narrows from left to right, the particles will gradually move towards the right end of the breather pipe 43 without falling out of the breather pipe 43. Since the clamping plug 42 and the breather pipe 43 are clamped to each other, when disassembling and cleaning the breather pipe 43, the clamping plug 42 and the breather pipe 43 can be separated to clean out the remaining impurities.

[0033] For the technical solution provided by the present utility model, when pouring paddy into the rice mill for feeding, first fix the feed bin 1 on the top of the rice mill through the mounting frame 2, and then pour paddy from the upper opening of the feed bin 1. The upper opening of the feed bin 1 trends to be larger at the top and smaller at the bottom. The paddy falls onto the turning plate blades on the outer wall of the rotating ring 44. Start the reduction motor 41 to drive the clamping plug 42, the breather pipe 43 and the rotating ring 44 to rotate. During the rotation of the turning plates, the turning plates stir the paddy. At the same time, start the hot air blower 47. The hot air blown by the hot air blower 47 is transmitted into the interior of the connecting pipe 45 through the hose 46, and then enters the interior of the breather pipe 43 from the connecting pipe 45 and blows out from the ventilation holes and communication holes. The apertures of the ventilation holes and communication holes are smaller than the paddy particles. While the turning plates stir and mix the paddy, the hot air is evenly blown between the paddy. The paddy particles are smaller than the particles of impurities such as stones. The paddy falls through the screening holes of the filter plate 3, and the stones stay on the top of the filter plate 3. Since the inner wall of the filter plate 3 fits the outer edge shape of the turning plate, while the turning plates stir and turn the paddy clockwise, every time the curved arc surface of the outer edge of the turning plate passes over the top of the filter plate 3, it will scrape the top of the filter plate 3 to scrape up the stones staying on the top of the filter plate 3. The stones temporarily stay on the arc surface of the turning plate. Continuously pour paddy from the top of the feed bin 1 for screening and feeding. After use, pull the filter plate 3 outward from the left side so that the filter plate 3 slides inside the feed bin 1. Some stones stay on the top of the filter plate 3, and some stones stay on the surface of the turning plate. Start the reduction motor 41 to drive the breather pipe 43 and the rotating ring 44 to rotate slowly. During the rotation of the rotating ring 44 and the turning plates, the stones attached to the surface gradually fall off and fall out from the bottom of the feed bin 1;

[0034] While using the breather pipe 43 and the turning plates to stir the paddy, some particles smaller than the ventilation holes and communication holes fall into the interior of the breather pipe 43. Since the inner wall of the breather pipe 43 is frustum-shaped and gradually narrows from left to right, the particles will gradually move towards the right end of the breather pipe 43 without falling out of the breather pipe 43. Since the clamping plug 42 and the breather pipe 43 are clamped to each other, when disassembling and cleaning the breather pipe 43, the clamping plug 42 and the breather pipe 43 can be separated to clean out the remaining impurities.

[0035] The present utility model covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
