Description

Technical Field

[0001] This utility model applies to the field of rice processing technology, and in particular relates to a rice milling machine that facilitates the removal of chaff. Background Technology

[0002] Currently, rice milling machines are mechanical devices used to process paddy rice into polished rice. Through mechanical friction and sieving, they efficiently remove the husk and bran layer while retaining the nutrients in the rice grains. Their core advantages include simple operation, high processing efficiency, and uniform quality of finished rice, which can meet the needs of families, small workshops, and large-scale rice mills in various scenarios.

[0003] However, in current rice milling machines, when the bran layer on the surface of paddy rice is removed by friction, the bran layer falls into the corresponding collection box along with the finished rice and is then separated. This method cannot quickly remove the bran layer that has detached from the paddy rice surface while processing the raw material. Furthermore, the separated bran layer is lightweight and easily dispersed into the air by external forces, affecting the collection of bran impurities and subsequent processing. Therefore, we propose a rice milling machine that facilitates bran removal. Utility Model Content

[0004] The main purpose of this invention is to provide a rice milling machine that facilitates the removal of chaff, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rice milling machine that facilitates chaff removal, wherein rotating rollers are rotatably arranged on both sides inside the processing frame, and a friction belt is movably sleeved on the outer side of each rotating roller; a feeding funnel is fixedly connected to the top of the processing frame; and a discharge trough is opened in the middle of the bottom of the processing frame.

[0007] A hollow frame is fixedly installed on the outside of the processing frame, and a waste storage frame is detachably installed at the bottom of the hollow frame by bolts. A negative pressure mechanism is provided on the outside of the hollow frame.

[0008] A spraying mechanism is provided on the top outer side of the hollow frame.

[0009] As an optional solution to the technical solution of this application, a negative pressure pump is fixedly installed on the bottom side of the hollow frame. A connecting pipe is vertically fixedly connected to the top of the negative pressure pump, and the bottom of the connecting pipe is connected to the air inlet of the negative pressure pump. A first fixing sleeve is fixedly installed at both ends of the outer side of the hollow frame. A gas collecting pipe is fixedly installed through the inner side of the two sets of first fixing sleeves, and the bottom side of the gas collecting pipe is fixedly connected to the top of the connecting pipe. A fixing pipe is fixedly connected to the side of the connecting pipe, and there are several sets of fixing pipes. The fixing pipes are fixedly installed through the inside of the side of the hollow frame, and the fixing pipes extend from the outside of the hollow frame to its inside. A suction pipe is fixedly connected to the top of the side of each fixing pipe.

[0010] By adopting the above technical solution, under the operation of the negative pressure pump and the connecting and conveying action of the gas collection pipe and the gas extraction pipe, the chaff layer impurities that detach from the surface of the rice can be directly sucked up during the process of processing the rice raw material and causing it to fall. This achieves rapid separation of the chaff layer and the rice raw material, reduces the operation steps required for separating the chaff layer impurities, and improves the efficiency of subsequent processing of the chaff layer impurities.

[0011] As an optional solution to the technical solution of this application, the spraying mechanism includes an atomizing nozzle. A second fixing sleeve is fixedly installed on both sides of the top of the hollow frame. A liquid collecting pipe is fixedly installed through the inner sides of the two sets of second fixing sleeves. A water supply pipe is fixedly connected to the middle of the side of the liquid collecting pipe. A conveying pipe is fixedly connected to the bottom of the liquid collecting pipe vertically. An atomizing nozzle is fixedly connected to the bottom of each conveying pipe, and the atomizing nozzle is located inside the hollow frame.

[0012] By adopting the above technical solution, the collection pipe and the atomizing nozzle are connected through the water supply pipe, so that the surface of the chaff layer impurities transported into the hollow frame can be covered with corresponding water droplets, thereby increasing the weight of the chaff layer impurities and ensuring that they can be quickly transported into the waste collection frame, avoiding arbitrary scattering during cleaning and affecting subsequent cleaning processes.

[0013] As an optional solution to the technical solution of this application, the hollow frame is fixedly installed on both sides inside, and a breathable baffle is slidably inserted between the inner sides of the two sets of the limiting frames. The air extraction pipe and the atomizing nozzle are respectively located on the outer sides of the breathable baffle. A waste discharge groove is opened at the bottom of the hollow frame, and the waste discharge groove is located on the outer side of the top of the waste collection frame. A guide plate is fixedly installed at an inclination on both sides inside the processing frame. An air suction groove is opened on the inner side of the processing frame, and the air suction groove is located below the rotating roller and above the outer side of the guide plate. A feed groove is opened inside the side of the hollow frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application discloses a rice milling machine that facilitates the removal of bran. This machine features a hollow frame on the outside of the processing frame and a negative pressure pump on the outside of the hollow frame. During operation, the negative pressure pump generates a corresponding negative pressure suction inside the air collecting pipe through a connecting pipe. This negative pressure suction is then transported to the hollow frame through a connecting pipe. Subsequently, through the connection of the waste discharge trough and the air suction trough, a corresponding negative pressure suction is generated inside the processing frame. During the processing of the rice grains, as they fall, the machine directly absorbs the bran impurities detached from the surface of the rice grains, thus achieving rapid separation of the bran layer and the rice grains. This reduces the number of steps required for separating the bran impurities and improves the efficiency of subsequent processing of the bran impurities.

[0016] 2. The present application provides a rice milling machine for easy bran removal. A liquid collection pipe is installed at the top of the hollow frame, and a conveying pipe and atomizing nozzle are installed at the bottom of the liquid collection pipe. The atomizing nozzle is positioned on the side of a permeable baffle. After the negative pressure pump draws the bran impurities into the hollow frame, the atomizing nozzle discharges water. This causes water droplets to adhere to the surface of the bran impurities conveyed into the hollow frame, thus increasing their weight and ensuring rapid transport to the waste collection frame. This prevents the impurities from scattering during cleaning and affecting subsequent cleaning processes. Attached Figure Description

Detailed Implementation

[0021] like Figure 1-3As shown, this utility model provides a technical solution: a rice milling machine that facilitates the removal of bran, wherein rotating rollers 12 are rotatably arranged on both sides inside the processing frame 1, and a friction belt 13 is movably sleeved on the outer side of each rotating roller 12, a feeding funnel 14 is fixedly connected to the top of the processing frame 1, and a discharge trough 15 is opened at the middle of the bottom of the processing frame 1.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a hollow frame 21 is fixedly installed on the outside of the processing frame 1. A waste storage frame 42 is detachably installed at the bottom of the hollow frame 21 by bolts. A negative pressure pump 25 is fixedly installed on the bottom side of the hollow frame 21. Under the control of an external controller, the negative pressure suction of the negative pressure pump 25 can be adjusted and controlled so that the negative pressure suction generated inside the processing frame 1 can only suck up the lighter bran layer impurities, and not suck up the heavier finished rice. A connecting pipe 24 is vertically fixedly connected to the top of the negative pressure pump 25, and the bottom of the connecting pipe 24 is connected to the negative pressure pump. The air inlets of 25 are connected. The outer ends of the hollow frame 21 are fixedly installed with first fixing sleeves 22. A gas collecting pipe 23 is fixedly installed through the inner side of the two sets of first fixing sleeves 22. The bottom side of the gas collecting pipe 23 is fixedly connected to the top of the connecting pipe 24. The side of the connecting pipe 24 is fixedly connected with a fixing pipe 27. There are several sets of fixing pipes 27. The fixing pipes 27 are fixedly installed through the inside of the side of the hollow frame 21. The fixing pipes 27 extend from the outside of the hollow frame 21 to its inside. The top of the side of each fixing pipe 27 is fixedly connected with an air extraction pipe 28.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), guide plates 11 are fixedly installed on both sides of the inside of the processing frame 1 at an angle. An air suction groove 2 is opened on the inside side of the processing frame 1, and the air suction groove 2 is located below the rotating roller 12 and above the outside of the guide plate 11. A feed groove 26 is opened inside the side of the hollow frame 21, and the feed groove 26 and the air suction groove 2 are at the same horizontal position and are connected.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a second fixing sleeve 3 is fixedly installed on both sides of the top of the hollow frame 21. A liquid collection pipe 31 is fixedly installed through the inner side of the two sets of second fixing sleeves 3. A water supply pipe 34 is fixedly connected to the middle of the side of the liquid collection pipe 31. A conveying pipe 32 is fixedly connected vertically to the bottom of the liquid collection pipe 31. There are several sets of conveying pipes 32. The conveying pipes 32 are fixedly installed through the top of the hollow frame 21 and extend from the outside of the hollow frame 21 to its interior. Atomizing nozzle 33 is fixedly connected to the bottom of each conveying pipe 32 and the atomizing nozzle 33 is located inside the hollow frame 21.

[0025] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), limit frames 4 are fixedly installed on both sides inside the hollow frame 21. A breathable baffle 41 is slidably inserted between the inner sides of the two sets of limit frames 4. The air extraction pipe 28 and the atomizing nozzle 33 are respectively located on the outer sides of the breathable baffle 41. A waste discharge groove 43 is opened at the bottom of the hollow frame 21, and the waste discharge groove 43 is located on the outer side of the top of the waste collection frame.

[0026] During operation, the external drive motor is activated via an external controller, causing it to rotate and drive the two sets of rotating rollers 12. Simultaneously, the negative pressure pump 25 is activated, and its negative pressure suction is adjusted so that the negative pressure suction generated inside the processing frame 1 can only suck up the lighter chaff impurities, not the heavier finished rice. As the rollers rotate, they drive the friction belt 13 to simultaneously transport the rice raw material bucket into the processing frame 1 via the feed funnel 14. Under the rotation of the rollers 12 and the friction belt 13, the chaff layer on the surface of the rice raw material is removed. During the simultaneous falling of the finished rice and chaff impurities, the lighter chaff impurities can be sucked up by the negative pressure pump. During operation, the negative pressure suction from the air intake trough 2 is used to draw water through the waste discharge trough 43 and transport it into the hollow frame 21. At the same time, with the operation of the external water pump, water can be continuously transported through the water supply pipe 34 to the liquid collection pipe 31, and then transported to the atomizing nozzle 33 through the connection of the delivery pipe 32. Under the structural action of the atomizing nozzle 33, the water is atomized and discharged into the hollow frame 21. This allows the bran layer impurities to adhere to the surface of the bran layer impurities while being drawn into the hollow frame 21, thus increasing their weight. Under the blocking action of the air permeable baffle 41, the bran layer impurities are discharged from the waste discharge trough 43 into the waste storage frame 42 for collection and treatment.
