Description

A feeding vertical emery roller rice mill

technical field

The invention relates to the technical field of rice mills, in particular to a feeding vertical emery roller rice mill.

Background technique

Rice milling machine is a commonly used agricultural machinery. It is a professional machine used to peel corn, sorghum, millet and other miscellaneous grains. Its working principle is to make brown rice enter the rice milling chamber of the rice milling machine. The rotation of the roller allows the rice grains to be fully rubbed and scraped between the rice grains, the rice grains and the sieve plate, and the rice grains and the rice roller to achieve the effect of removing the surface rice skin and obtaining a smooth and bright appearance. Nowadays, in the rice milling industry There are two types of rice mills used: horizontal rice mills and vertical rice mills. The main shaft of the rollers of the horizontal rice mills is horizontal and the whitening chamber is horizontal in space. The roller spindle of the vertical rice mill is designed vertically and the whitening room is in a vertical position in space. The whitening and crushing rate and the whitening uniformity of the two are also different.

Since the gravity of the rice grain fluid in the whitening chamber of the vertical rice mill speeds up the speed of the rice grains passing through the whitening chamber, when the same roller structure parameters and motion parameters as those of the horizontal rice mill are used, the gravity makes the rice grains in the machine The milling time is shorter than that of the horizontal rice mill, and the milling effect on the rice grains is slightly weaker. If the milling time of the rice grains is shortened, the number of rolls during the whitening process is relatively reduced, and the whitening uniformity is worse than that of the horizontal rice mill. , so in actual production, multi-stage whitening is used to improve the uniformity of whitening. Generally, 4 or 5 stages of whitening are better, which can not only ensure good whitening uniformity, but also reduce broken rice by multi-machine light milling. However, in small and medium-sized grain processing workshops, due to cost reasons, there is no condition to purchase multiple rice mills for multiple whitening processes. Usually, the method of manual handling is used to collect each whitening process from the outlet below the rice mill. The rice grains are poured into the feeding trough above the rice milling machine again, which requires frequent operation and low efficiency, and because the height of the rice milling machine is relatively high relative to people, the rice collected from the bottom needs to be transported to the rice milling machine every time it is transported The feeding trough on the top is more labor-intensive.

For this reason, a feeding vertical emery roller rice mill is proposed. Through the circulation device, the whitened rice grains are automatically transported to the feeding trough for multi-pass whitening, without frequent operation, and the processing efficiency is improved.

Contents of the invention

The purpose of the present invention is to provide a kind of feeding vertical emery roller rice whitening machine, the rice grains after whitening are automatically retransported from the discharge port to the feeding trough for multi-pass whitening through the circulation device, so as to solve the problems in the above-mentioned background technology. proposed question.

To achieve the above object, the present invention provides the following technical solutions:

A feeding vertical emery roller rice milling machine, comprising a rice milling machine, a support frame and a motor 1, wherein: the top of the rice milling machine is provided with a feeding trough, and the side is provided with a discharge port, and the rice milling machine Bottom is fixedly installed with support frame by threaded connection, and described support frame is equipped with motor one that provides power for rice milling machine by belt transmission.

A circulation device, the circulation device is connected to the discharge port and the feed tank of the rice mill, and the circulation device is used to transport the rice grains whitened by the rice mill to the feed tank from the discharge port for further processing.

Preferably, the circulation device includes a feed pipe, a screw conveyor, a discharge pipe, and a second motor. The outlet of the rice mill is detachably installed on one end of the feed pipe, and the other end of the feed pipe is fixedly connected to the screw. The feed inlet below the conveyor, the top of the screw conveyor is fixedly connected to one end of the discharge pipe, and the discharge end of the discharge pipe extends out to connect to the feed trough, and the bottom of the screw conveyor is connected to a power supply for the screw conveyor. motor two. After the rice grains are processed inside the rice mill, the rice grains will flow out from the discharge port. At this time, the rice grains flowing out from the discharge port will flow into the feeding pipe, because there is a height difference between the discharge port and the feed port below the screw conveyor. Therefore, under the action of gravity, the rice grains flow into the material inlet below the screw conveyor through the inclined feeding pipe. At this time, the screw conveyor uses the motor 2 to drive the internal spiral blade to rotate, and the rotation of the spiral blade will transfer the grains in the tank box. The rice grains are transported upwards, and when the rice grains are transported to the top and reach the position of the discharge pipe, the rice grains flow out through the inclined discharge pipe. Since the discharge end of the discharge pipe is connected to the feed trough, the rice grains flowing out just flow into the inlet. Feed trough. Under the action of the screw conveyor, the rice grains can be circulated and processed, and the flow rate is stable during the processing, which reduces the phenomenon of traditional rice milling machines that cause a large number of rice grains to accumulate in the hopper at the same time, causing the feeding trough to be blocked.

Preferably, the bottom surface of the feeding pipe is provided with a discharge hole, and the bottom of the inner wall of the feeding pipe is installed with a switching door through a hinge. , and the switching door and the discharge hole magnetically cooperate with each other. When the switching door is opened to the inside, the feeding pipe is just closed. The end of the switching door away from the hinge is provided with a small groove. And the extended end of the elastic plunger cooperates with the small groove, and a handle 1 is fixedly installed on the switching door. When the rice grain cycle processing is completed, manually push the switching door to the inside of the feeding tube, and the elastic plunger installed on the inner wall of the feeding tube retracts under the extrusion of the switching door, and when it moves to the position of the small groove, the elastic plunger pops up and switches The door is fixed. When the switching door is fixed inside the feeding pipe, on the one hand, the feeding pipe is closed to stop conveying the rice grains to the screw conveyor for further processing, and on the other hand, the processed rice grains flow out from the discharge hole. Place it under the discharge hole to collect the processed rice grains. When the collection is complete, you can pull the switching door back through the handle. The switching door and the discharge hole are fixed by magnetic attraction, and you are ready for the next cycle processing.

Preferably, an induction circuit is connected to the bottom of the elastic plunger, and is electrically connected to the second motor when the extended end of the elastic plunger is pressed back. When the rice grain cycle processing is completed, push the switching door to the inside of the feeding pipe, and the elastic plunger installed on the inner wall of the feeding pipe retracts under the extrusion of the switching door. At this time, the feeding pipe is closed, and the rice grains stop being discharged from the rice mill. The inlet flows into the material inlet below the screw conveyor. When the elastic plunger is squeezed, it means that no rice grains have entered the material inlet at this time. Through the electrical connection, the motor 2 will be powered off after a period of time. This design can make the screw conveyor The rice grains inside the machine are all conveyed to the feeding trough and then stop working.

Preferably, the top of the feeding pipe is provided with an observation hole, and the top of the outer wall of the feeding pipe is rotated through the second hinge to install an observation door that cooperates with the observation hole. It is installed on the side wall of the observation door, and the second handle is fixedly installed on the observation door through screw connection. After the rice grains have been processed in a cycle for a period of time, it is necessary to manually observe whether the processing degree of the rice grains has reached the expected effect. At this time, the observation door can be opened to the outside by the handle, and a small amount of rice grains can be reached into the observation hole for observation. When the rice grains have reached the expected effect, you can close the observation door and push open the switching door to collect the rice grains from the bottom of the feeding pipe. When the expected effect is not achieved, you can close the observation door and wait for it to continue to circulate for a period of time before observing again.

Preferably, the bottom side of the screw conveyor is provided with a discharge port, the outer wall of the screw conveyor is fixedly installed with an upper hopper connected to the discharge port, the outer wall of the screw conveyor is provided with a sliding groove, and the sliding groove is installed There is a sealed door that cooperates with the discharge port. The upper hopper is used to feed unprocessed rice grains into the screw conveyor, because for traditional rice mills fed from above, the height of the feed trough is relatively high compared to the person, and it is inconvenient to put the rice grains into the feed trough, so the screw conveyor There is a discharge opening on the side of the bottom of the conveyor, which can be directly loaded on the bottom of the screw conveyor. After loading, the screw conveyor automatically transports the rice grains upwards to the feeding trough of the rice mill. When the inside of the screw conveyor has certain requirements for sealing, slide troughs are set on both sides of the discharge port, and then the airtight door is installed in the chute to be opened and closed freely up and down, and the airtight door is closed after feeding to ensure The tightness does not affect its normal operation.

Preferably, a feeder is installed at the bottom of the inner wall of the upper hopper, and a motor three for powering the feeder is installed below the upper hopper. In order to effectively avoid the occurrence of material blocking inside the upper hopper, a feeder is installed at the bottom of the inner wall of the upper hopper. The feeder is composed of a main shaft and multiple blades, and the output end of the motor three is connected to its main shaft. The feeder works At this time, the three output ends of the motor connected under the upper hopper rotate to drive the main shaft and the blades to rotate, and the rice grains are swept into the discharge port under the action of the blades to realize the function of auxiliary feeding. After the feeding is completed, the feeder and the seal are closed Door.

Preferably, a material level sensor is fixedly installed under the inner wall of the upper hopper through threaded connection, an electromagnet that cooperates with the top of the sealed door is fixedly installed on the outer wall of the screw conveyor, and the material level sensor is electrically connected to the motor three and on the electromagnet. The material level sensor can sense the current amount of rice in the upper hopper. Since the inside of the screw conveyor has certain requirements for airtightness during transportation, when all the rice grains in the upper hopper flow into the screw conveyor, it is necessary to close the airtight door in time to avoid Affecting its normal operation, at this time, the mutual cooperation between the electromagnet and the top wall of the airtight door can realize that the airtight door will be automatically closed when the rice grains completely flow into the screw conveyor. The electricity generates magnetism, and generates magnetic attraction with the top of the sealing door to fix the sealing door above the sealing port, and then the feeder can be started to start feeding. At this time, the material level sensor also starts to detect the material level inside the hopper. When After sensing that the rice grains inside the upper hopper are basically transported to the screw conveyor by the feeder, the electromagnet is powered off through the electrical connection. Cooperate to form a seal, and also cut off the power of the three motors through electrical connection, and automatically stop the feeder from working.

Preferably, the inner wall of the upper hopper is provided with a scale groove for judging the loading amount, and the function of the scale groove is to observe the discharge amount in the upper hopper at this time. Since the circulation device needs to have precise control over the amount of feeding each time, if the amount of feeding is too large, the rice grains have not been completely fed after a cycle in the screw conveyor and rice mill, and the feeding cannot be continued at this time , forming accumulations in the upper hopper, and the airtight door cannot be closed, and the rice grains in the screw conveyor will flow out, affecting normal use; if the feeding amount is too small, the rice grains have not completed a cycle in the screw conveyor and rice milling machine After the material has been loaded, a section of vacant part is formed inside the screw conveyor and the rice mill at this time, which not only reduces the processing efficiency, but also affects the processing effect of the equipment. For this reason, a scale groove is set on the inner wall of the upper hopper, and an appropriate amount of rice grains can be added each time before starting the screw conveyor and rice milling machine, and then opening the sealed door to start the feeder, so as to ensure that when the processing material is loaded in each cycle, the first inflow The rice grains will be transported to the discharge port after being processed by the rice milling machine. At this time, the airtight door is closed, which not only ensures the processing efficiency but also the processing effect.

Preferably, a counterweight is installed on the top of the airtight door, and the bottom is wedge-shaped. When it is sensed that the rice grains inside the upper hopper are basically transported to the screw conveyor by the feeder, the electromagnet is powered off through an electrical connection. At this time, the magnetism of the electromagnet disappears, and the airtight door falls under the action of gravity. Due to the position of the feeder blade, the material level sensor cannot be installed at the bottom. Otherwise, there will still be some rice grains that have not been conveyed into the screw conveyor at the bottom of the upper hopper at this time. , the function of increasing the counterweight is to increase the gravitational potential energy of the airtight door, which can more effectively ensure that the airtight door falls to the bottom of the discharge port. There may be gaps between the airtight door and the side of the screw conveyor due to the existence of rice grains, which will affect the screw. The airtightness of the conveyor affects the conveying effect. At this time, the bottom of the airtight door is designed as a wedge, which can effectively prevent the rice grains from being stuck between the airtight door and the discharge port after the airtight door falls, greatly reducing the probability of gaps to ensure The tightness of the screw conveyor.

Compared with prior art, the beneficial effect of the present invention is:

1. Compared with the traditional vertical emery roller rice whitening machine, when multiple whitening processes are required, manual handling is usually used, and the rice grains after each whitening process are re-poured from the outlet below the rice whitening machine. The feeding trough above the rice mill is inefficient and labor-intensive. The invention automatically re-transports the whitened rice grains from the outlet to the feeding trough for reprocessing through the circulation device, which improves the processing efficiency.

2. When loading materials, the traditional vertical emery roller rice mill usually adopts the method of feeding from the top and discharging from the bottom. Since the discharge port of the rice mill is relatively high compared to the height of the person, each time it is put in The weight of the rice grains is also relatively large, and all are manual operations, which are more labor-intensive. The present invention can realize the lower feeding and lower discharging through the feeding port provided on the circulation device, which saves manpower.

3. When feeding the rice milling machine, the traditional vertical emery roller rice milling machine usually may cause material blocking at the feed port. The present invention uses a circulation device to stabilize the flow of rice grains during the processing process. The rice grains flowing out of the circulation device gradually flow into the feeding trough of the rice mill. Compared with the traditional one-time pouring of a large amount of rice grains into the feeding hopper, the invention is less prone to material blocking.
