Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to a brown rice discharge elevator. Background Technology
[0002] A hoist is a machine that transports objects from a low place to a high place. The outlet of a brown rice silo is usually located at the bottom to facilitate more thorough unloading and to solve the problem of difficult unloading of brown rice from the bottom of the silo. Therefore, a hoist is needed in the process of unloading brown rice.
[0003] In existing technologies, conveyor belt elevators or tray elevators are commonly used. Conveyor belt elevators have a small lifting angle to prevent brown rice from slipping, resulting in a large size. Tray elevators are prone to spillage during the conveying process. Using a vacuum feeder as an elevator can overcome the above disadvantages, but the operation of a vacuum feeder requires sufficient airflow to move the brown rice. However, brown rice particles are small and have poor internal airflow, resulting in poor feeding effect of the vacuum feeder. Utility Model Content
[0004] The purpose of this utility model is to provide a brown rice discharge elevator, which can control the brown rice in the rice bin to enter the feeding bin through the feeder, and mix the brown rice and air during the falling process through the feeding bin and send it into the lifting pipe, and ensure that there is sufficient airflow to carry the brown rice.
[0005] This utility model provides a brown rice discharge elevator, comprising:

[0029] Combination Figures 1 to 5 As shown, the brown rice discharge elevator provided by this utility model includes a vacuum elevator and a feeder 3.
[0030] Combination Figures 1 to 5 As shown, the vacuum elevator includes a lifting pipe 1 and a feeding bin 2. The inlet end of the lifting pipe 1 is fixedly connected to the inside of the feeding bin 2. A ventilation opening 21 is provided on the side wall of the feeding bin 2 away from the lifting pipe 1. The top of the feeding bin 2 is connected to the rice bin outlet. The feeder 3 includes a auger blade 31, a motor 32 and a control terminal. The motor 32 drives the auger blade 31. The control terminal is electrically connected to the motor 32 to control the rotation speed of the auger blade 31. The auger blade 31 is rotatably mounted in the rice bin outlet. The rice bin outlet faces downward and is connected to the feeding bin 2. The rice bin outlet is located between the lifting pipe 1 and the ventilation opening 21.
[0031] In this embodiment, the feeder 3 controls the brown rice in the rice bin to enter the feeding bin 2. Air enters the feeding bin 2 through the vent 21 and drives the brown rice to move towards the lifting pipe 1. The brown rice falls naturally between the vent 21 and the lifting pipe 1. During the natural fall, the brown rice is carried into the lifting pipe 1 by the flowing air, so as to achieve full mixing of brown rice and flowing air and ensure that there is enough flowing air to carry the brown rice.
[0032] In this embodiment, the control terminal controls the rotation speed of the auger blades 31 via the motor 32 to control the speed at which brown rice enters the feed hopper 2, thus preventing excessive brown rice from entering the feed hopper 2 and causing air circulation difficulties.
[0033] In some embodiments, combined with Figure 3As shown, a grid baffle 22 is fixedly installed inside the feeding hopper 2. The four sides of the grid baffle 22 are attached to the inner wall of the feeding hopper 2. The grid baffle 22 is inclinedly arranged directly below the discharge port of the feeder 3. The ventilation port 21 and the feeder 3 are located on both sides of the grid baffle 22. The grid baffle 22 can firstly prevent the brown rice from being lost through the ventilation port 21. At the same time, the grid baffle 22 can prolong the time that the brown rice stays in the air and improve the airflow effect on the brown rice.
[0034] In some embodiments, combined with Figure 2 As shown, the outlet end of the lifting pipe 1 is integrally formed with an outlet chamber 11, and the outlet end of the lifting pipe 1 is connected to the outlet chamber 11. The vacuum generator of the vacuum lifting machine is fixedly connected to the top plate of the outlet chamber 11, and the inlet end of the vacuum generator is connected to the interior of the outlet chamber 11. The outlet of the outlet chamber 11 is opened on the side wall away from the outlet end of the lifting pipe 1. The vacuum generator of the vacuum lifting machine is installed in the outlet chamber 11 to avoid the blockage problem after the vacuum generator is installed in the lifting pipe 1.
[0035] In some embodiments, combined with Figure 4 As shown, at least two lifting pipes 1 are connected in series inside the vacuum lifting machine. The inlet end of the subsequent lifting pipe 1 is fixedly connected to the outlet of the outlet chamber 11 of the preceding lifting pipe 1. The brown rice is transported in segments to the designated height through multiple lifting pipes 1 connected in series.
[0036] In some embodiments, combined with Figure 2 , Figure 5 As shown, a sealing gate is fixedly installed on the outlet chamber 11. The outlet end of the lifting pipe 1 and the vacuum generator of the vacuum elevator are located on the same side of the sealing gate, and the outlet of the outlet chamber 11 is located on the other side of the sealing gate. The sealing gate increases the sealing performance by closing during the transportation of brown rice by the lifting pipe 1, ensuring the transportation process. The sealing gate opens when the brown rice is discharged to ensure the discharge of the brown rice. When the lifting pipes 1 are connected in series, the sealing gate is half-open to cooperate with the brown rice inside to ensure the independent sealing of each lifting pipe 1, ensuring that each lifting pipe 1 operates simultaneously and improving the transportation speed.
[0037] In some embodiments, combined with Figure 3 , Figure 5 As shown, the bottom plates of the feed hopper 2 and the outlet hopper 11 are both inclined. The bottom plate of the feed hopper 2 is inclined upward on the side near the ventilation opening 21, and the bottom plate of the outlet hopper 11 is inclined upward on the side near the outlet end of the lifting pipe 1. Compared with a horizontal ground, the inclined ground is conducive to the accumulation of brown rice. The greater height difference of the accumulated brown rice is conducive to the flow of air to carry the brown rice into the lifting pipe 1. The accumulation position of the brown rice is controlled by the inclination direction to ensure that the flow of air can pass through smoothly.
[0038] In some embodiments, combined with Figure 1 , Figure 4 As shown, the lifting pipe 1 is S-shaped. The horizontal height of the inlet end of the lifting pipe 1 is lower than the horizontal height of the outlet end of the lifting pipe 1. The main lifting end in the middle of the S-shaped lifting pipe 1 has a high verticality, which is not conducive to the brown rice adhering to the side wall of the lifting pipe 1, but is conducive to the transportation of brown rice.
[0039] In some embodiments, combined with Figure 3 , Figure 5 As shown, an air vent valve 12 is fixedly installed on the outer wall of the lifting pipe 1. The outlet of the air vent valve 12 faces downward. The air vent valve 12 is connected to the lowest point of the inner cavity of the lifting pipe 1. In case of an accident, the brown rice in the lifting pipe 1 can be quickly discharged by opening the air vent valve 12 to solve the blockage problem and ensure the cleanliness of the lifting pipe 1.
[0040] In some embodiments, combined with Figure 3 As shown, the motor 32 is fixedly installed inside the rice bin outlet. The drive end of the motor 32 is fixedly connected to the auger blade 31 with its upward facing direction. Since the auger blade 31 rotates during operation, it is less likely to clog with brown rice compared to the basically stationary motor 32, thus alleviating the clogging problem.
[0041] In some embodiments, combined with Figure 3 As shown, the tip of the auger blade 31 extends into the rice bin, which can increase the contact effect between the auger blade 31 and the brown rice, improve the control of the brown rice, and at the same time avoid the brown rice from clogging at the junction of the rice bin and the outlet.
[0042] Working process: Brown rice enters the feeding hopper 2 through the rice bin outlet under the action of the feeder 3. The vacuum generator of the vacuum elevator starts to work and generates negative pressure. Air is introduced into the lifting pipe 1 through the vent 21. The air is driven by the negative pressure to generate suction. As the air enters the lifting pipe 1, it passes the falling position of the brown rice entering the feeding hopper 2. The brown rice mixes with the air during the falling process, and the air flow carries the brown rice into the lifting pipe 1.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
