Abstract
Description
Technical Field
[0001] This application relates to the field of filling technology, specifically to a rice filling machine. Background Technology
[0002] my country is a major agricultural country, with a rice planting area of approximately 450 million mu (about 30 million hectares), ranking second in the world. my country has a large population, high consumption, and significant waste. About 50% of the population in China relies on rice as a staple food, and rice cultivation accounts for about 30% of the total grain crop area, with rice production approaching half of the total grain output. Therefore, rice processing is particularly important. After harvesting, impurities are removed from the paddy, the husk is removed, brown rice is extracted, and the bran layer is milled to produce graded white rice with minimal broken rice and impurities. Rice is an indispensable food in daily life. Currently, rice production and packaging typically use woven bags or plastic bags, usually filled by filling machines. To increase packaging speed, multiple openings are used simultaneously. When a bag under one opening is full, rice cannot enter through that opening and must be replaced with an empty bag immediately. This reduces the filling speed of the filling machine, which is detrimental to production. Utility Model Content
[0003] The purpose of this application is to overcome the above-mentioned technical deficiencies and provide a rice filling machine to solve the problem of reduced total filling speed when a single packaging port is full in the prior art.
[0004] To achieve the above-mentioned technical objectives, the technical solution of this application is as follows: A rice filling machine includes a hopper, a discharge trough, a discharge pipe, and an overflow pipe, wherein: a receiving cavity is formed inside the hopper, and multiple discharge ports are opened at the lower end; the discharge trough is arranged below the hopper, and an inclined discharge slide is formed inside the discharge trough; the upper ends of the multiple discharge pipes are connected to the discharge slide, and the multiple discharge ports correspond vertically to the positions of the multiple discharge pipes; the upper end of the overflow pipe is connected to the discharge slide, and the connection between the overflow pipe and the discharge slide is lower than the sliding connection between the discharge pipe and the discharge pipe.
[0005] Preferably, the rice filling machine further includes multiple gate valves, which are respectively disposed in multiple unloading pipes.
[0006] Preferably, the gate valve is also disposed in the overflow pipe.
[0007] Preferably, the rice filling machine further includes multiple receiving pipes, which are arranged below the unloading pipe and the overflow pipe.
[0008] Preferably, the rice filling machine further includes multiple mass meters, which are disposed between the unloading pipe and the receiving pipe to measure the load weight of the receiving pipe.
[0009] Preferably, the mass meter is also disposed between the overflow pipe and the receiving pipe for measuring the load weight of the receiving pipe.
[0010] Preferably, the rice filling machine further includes a bag clamping mechanism, which includes a clamping plate, an elastic unit, and an electromagnet. The upper end of the clamping plate is hinged to the receiving pipe. The elastic unit is connected to both the clamping plate and the receiving pipe to provide an upward rotational force for the clamping plate. The electromagnet is fixed to the receiving pipe and corresponds to the lower end of the clamping plate to provide a downward suction force for the clamping plate.
[0011] Preferably, at least two of the bag clamping mechanisms are provided at each of the receiving tubes.
[0012] Preferably, the rice filling machine further includes a conveyor belt, which is disposed below the unloading pipe.
[0013] Preferably, there are two overflow pipes.
[0014] Compared with the prior art, the beneficial effects of this application include: rice in the hopper enters each packaging bag through the unloading pipe. After a packaging bag is full, the rice will accumulate in the unloading chute and slide downwards into the next unloading pipe. Therefore, the filling speed of the next unloading pipe increases, and the total filling speed of rice will not slow down because a packaging bag is full. After all the packaging bags corresponding to the unloading pipes are full, the rice will enter the overflow pipe. The rice filling speed will not slow down because all the packaging bags corresponding to the unloading pipes are full, until the packaging bag corresponding to the overflow pipe is full of rice.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] Please see Figure 1 and Figure 2 This embodiment provides a rice filling machine, which includes a hopper 1, a discharge trough 2, a discharge pipe 3, and an overflow pipe 4. The hopper 1 is used to hold rice, the discharge trough 2 is used to receive the rice falling from the hopper 1, the discharge pipe 3 is used to fill the rice into a packaging bag, and the overflow pipe 4 is used to discharge the rice from the end of the discharge trough 2.
[0020] The hopper 1 forms a receiving cavity 1a. The hopper 1 is wider at the top and narrower at the bottom to facilitate feeding. Multiple discharge ports 1b are opened at the bottom to pour the rice in the receiving cavity 1a downwards.
[0021] The unloading chute 2 is located below the hopper 1, and an inclined unloading slide 2a is formed inside the unloading chute 2, so the rice in the unloading slide 2a can also move from high to low.
[0022] The upper ends of multiple unloading pipes 3 are connected to the unloading slide 2a, and multiple unloading ports 1b correspond one-to-one with the positions of multiple unloading pipes 3. The rice in the unloading pipes 3 falls directly into the corresponding unloading port 1b.
[0023] The upper end of the overflow pipe 4 is connected to the unloading slide 2a, and the connection between the overflow pipe 4 and the unloading slide 2a is lower than the connection between the unloading pipe 3 and the unloading slide. When the unloading pipe 3 is not blocked, all the rice enters the unloading pipe 3. When the unloading pipe 3 is blocked, the rice cannot enter the unloading pipe 3 and will accumulate and slide down from the unloading slide 2a into the next unloading pipe 3. Only when all the unloading pipes 3 are blocked will the rice slide to the overflow pipe 4 and fall from the overflow pipe 4. There are two overflow pipes 4. The rice will only enter the overflow pipe 4 when the packaging bags under all the unloading pipes 3 are full of rice, and it will enter the higher overflow pipe 4 first. Setting two overflow pipes 4 can allow the excess rice under the packaging bags under the higher overflow pipe 4 to enter the lower overflow pipe 4 when the packaging bags under the higher overflow pipe 4 are full, thus increasing the overflow capacity.
[0024] Preferably, the rice filling machine also includes multiple gate valves 5, which are respectively installed in multiple discharge pipes 3. The gate valves 5 are used to block the corresponding discharge pipe 3 when the packaging bag below the discharge pipe 3 is full of rice, preventing excessive rice from being filled into the packaging bag. Furthermore, the gate valves 5 can be electrically operated for easy control. Additionally, the gate valves 5 are also installed in the overflow pipe 4, which can also block the corresponding overflow pipe 4 when the packaging bag below the overflow pipe 4 is full of rice.
[0025] Preferably, the rice filling machine also includes multiple receiving pipes 6, which are located below the unloading pipe 3 and the overflow pipe 4. The receiving pipes 6 are used to fix the packaging bag. Further preferably, the rice filling machine also includes a bag clamping mechanism 8, which includes a clamping plate 8a, an elastic unit 8b, and an electromagnet 8c. The upper end of the clamping plate 8a is hinged to the receiving pipe 6. The elastic unit 8b is connected to both the clamping plate 8a and the receiving pipe 6 to provide an upward rotational force for the clamping plate 8a. The electromagnet 8c is fixed to the receiving pipe 6 and corresponds to the lower end of the clamping plate 8a to provide a downward attraction force for the clamping plate 8a. When installing the packaging bag, the upper side of the packaging bag is placed over the outside of the receiving pipe 6, and the clamping plate 8a is pushed downward. When the clamping plate 8a enters the magnetic range of the electromagnet 8c, it is attracted by the electromagnet 8c, firmly fixing the packaging bag to the outside of the receiving pipe 6. When it is necessary to remove the packaging bag, the electromagnet 8c is de-energized, the magnetism disappears, and the clamping plate 8a rotates upward under the action of the elastic unit 8b, separating from the packaging bag. Further preferably, at least two bag clamping mechanisms 8 are provided at each receiving pipe 6. Multiple bag clamping mechanisms 8 can make the clamping of the packaging bag more stable. Preferably, the elastic unit 8b is a spring.
[0026] Preferably, the rice filling machine also includes multiple mass meters 7, which are installed between the unloading pipe 3 and the receiving pipe 6 to measure the load weight of the receiving pipe 6, thereby measuring the mass of the packaging bag connected to the corresponding receiving pipe 6, and thus measuring the mass of the rice in the packaging bag. The mass meters 7 are also installed between the overflow pipe 4 and the receiving pipe 6 to measure the load weight of the receiving pipe 6, thereby measuring the mass of the rice in the corresponding packaging bag below the overflow pipe 4. In a further preferred embodiment, the mass meter 7 is electronic. When the rice in the packaging bag reaches the predetermined weight, it sends a signal to the controller. The controller de-energizes the corresponding electromagnet 8c and closes the corresponding gate valve 5, preventing rice from entering the corresponding unloading pipe 3. The packaging bag falls due to its own weight, the mass meter 7's measurement value returns to zero, and it sends a signal to the controller. The controller then energizes the electromagnet 8c, allowing the packaging bag to be installed. In a further preferred embodiment, an infrared sensor can be installed on the outside of the unloading pipe 3. When a packaging bag is detected, it outputs a signal, and the controller opens the gate valve 5, allowing rice to flow into the packaging bag. When no packaging bag is detected, the controller keeps the gate valve 5 closed. In a further preferred embodiment, an alarm can be added. When the weight of rice in the packaging bag below the overflow pipe continues to increase, an alarm is triggered, reminding staff that the packaging bag below the unloading pipe 3 is full and needs to be replaced promptly.
[0027] Preferably, the rice filling machine also includes a conveyor belt 9, which is located below the unloading pipe 3, and a conveyor bag is used to transport packaging bags filled with rice.
[0028] In summary, the rice filling machine provided in this application allows rice in the hopper 1 to enter various packaging bags through the discharge pipe 3. After a packaging bag is full, the rice will accumulate in the discharge chute 2a and slide downwards into the next discharge pipe 3. Therefore, the filling speed of the next discharge pipe 3 increases, and the total filling speed of rice will not slow down because a packaging bag is full. After all the packaging bags corresponding to the discharge pipes 3 are full, the rice will enter the overflow pipe 4. The rice filling speed will not slow down because all the packaging bags corresponding to the discharge pipes 3 are full, until the packaging bags corresponding to the overflow pipe 4 are full of rice.
