Description

Technical Field

[0001] This utility model relates to the field of taro impurity removal technology, specifically to a conveying mechanism with impurity removal function for a taro harvester. Background Technology

[0002] Taro, also known as taro root, is the underground corm of a plant in the Araceae family. Its shape and texture vary depending on the variety; the edible type is usually the small taro. It is a perennial tuberous plant, often cultivated as an annual crop. The leaves are shield-shaped with long, thick petioles, green or purplish-red. A short stem forms at the base of the plant, gradually accumulating nutrients and enlarging into a fleshy corm, called "taro" or "mother taro," which can be spherical, oval, elliptical, or tuberous.

[0003] Taro is widely cultivated and harvested using taro harvesters. Most taro harvesters perform screening during the harvesting process before transporting the taro to the grain storage. However, since taro grows in the soil, some soil or impurities may remain on the surface. This residue increases the moisture content of the taro and the chance of bacterial growth. Especially if the soil contains bacteria or fungi, it will accelerate the taro's decay and shorten its shelf life. To address these issues, a taro harvester with a conveying mechanism that incorporates impurity removal is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a conveying mechanism with impurity removal function for a taro harvester. This solves the problem that most current taro harvesters screen the taro during harvesting before transporting it to the grain silo. However, since taro grows in the soil, some soil or impurities may still remain on the surface. The residue of soil and impurities may increase the moisture content of the taro and the chance of bacterial growth. In particular, if the soil contains bacteria or fungi, they will accelerate the rot process of the taro and shorten its shelf life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a conveying mechanism with impurity removal function for a taro harvester, including a mounting frame, an impurity removal component mounted on the top of the mounting frame, two connecting seats fixedly connected to the front and rear sides of the mounting frame, connecting rods fixedly connected above the four connecting seats, a mounting frame fixedly connected between the four connecting rods, a mesh conveyor belt for conveying taro installed inside the mounting frame, several guide baffles fixedly connected to the surface of the mesh conveyor belt, and a U-shaped guide groove fixedly connected to the bottom of the mounting frame through a connecting piece.

[0006] Preferably, a drive source for driving the mesh conveyor belt is fixedly installed on the upper front side of the mounting frame.

[0007] Preferably, the impurity removal component includes a fixed frame, which is fixedly connected to the top of the mounting bracket and located below the guide channel. The inside of the fixed frame is separated into a clean water tank and a wastewater tank by a partition. An mounting plate is fixedly connected to the top of the fixed frame at the position of the clean water tank.

[0008] Preferably, a drain pipe is fixedly connected to the left front end of the fixed frame at the location of the sewage tank, and a filling pipe is fixedly connected to the middle upper part of the mounting plate.

[0009] Preferably, a centrifugal water pump is fixedly connected to the upper right side of the mounting plate, an inlet pipe is fixedly connected to the input end of the centrifugal water pump, the end of the inlet pipe extends into the interior of the clean water tank, and a filter sleeve is fixedly connected to the outer side of the end of the inlet pipe. A delivery pipe is fixedly connected to the output end of the centrifugal water pump.

[0010] Preferably, the impurity removal component further includes two pipe clamps, both of which are fixedly connected to the upper rear side of the mounting frame. A main pipe is fixedly connected between the two pipe clamps, and an elbow is fixedly connected to the upper right side of the main pipe. The other end of the elbow, away from the main pipe, is fixedly connected to the end of the conveying pipe.

[0011] Preferably, at least five branch pipes are fixedly connected to the front side of the main pipe, and several spray heads are fixedly connected to the bottom of each of the five branch pipes.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: This utility model adopts a combination of "high-pressure water flushing + mesh filtration". After the centrifugal water pump pressurizes the clean water, it forms a dense water curtain through the spray head of the branch pipe, which fully covers the surface of the taro and washes away the attached soil, fine sand and other impurities. The impurities are discharged with the water flow through the mesh of the mesh conveyor belt, which prevents bacteria / fungi in the soil from accelerating the taro to rot, prolongs the shelf life of the taro and reduces storage losses. The impurity removal component adopts a "dual-box separation" design. The partition in the fixed frame divides the space into a clean water tank and a wastewater tank. The clean water is only used for one flushing to avoid the backflow of dirty water. The filter sleeve at the end of the water inlet pipe can filter out a small amount of impurities in the clean water tank, preventing the water pump or spray head from clogging and extending the equipment life. The wastewater is discharged centrally through the sewage pipe or treated later, which saves water compared with the traditional "non-recovery water flushing" and reduces the water resource consumption cost of field operations.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Reference Figure 1 - Figure 6As shown, a conveying mechanism with a cleaning function for a taro harvester includes a mounting frame 1. The mounting frame 1 serves as the core supporting foundation of the overall mechanism, providing stable installation conditions for the cleaning component 10 above it. It can also be installed on the taro harvester by welding. The cleaning component 10 is installed on the top of the mounting frame 1. Two connecting seats 2 are fixedly connected to both the front and rear sides of the mounting frame 1. Connecting rods 3 are fixedly connected to the top of each of the four connecting seats 2. A mounting frame 4 is fixedly connected between the four connecting rods 3. A mesh conveyor belt 5 for conveying taro is installed inside the mounting frame 4. 5. Due to its mesh design, small impurities such as mud and pebbles attached to the taro can be naturally leaked off during the conveying process. Rubber baffles can be installed between the upper and lower belts of the mesh conveyor belt 5 to scrape off the impurities that fall between the two conveyor belts and prevent the impurities from affecting the rotation of the conveyor belt rollers. This is existing technology and will not be elaborated on here. Several guide baffles 6 are fixedly connected to the surface of the mesh conveyor belt 5. The guide baffles 6 are used to lift the taro and prevent the taro from falling under the action of gravity. The bottom of the mounting frame 4 is fixedly connected to a U-shaped guide groove 8 through the connecting piece 9.

[0018] Specifically, a drive source 7 for driving the mesh conveyor belt 5 is fixedly installed on the upper front side of the mounting frame 4. The drive source 7 can be a speed reducer or a servo motor.

[0019] Specifically, the impurity removal component 10 includes a fixed frame 1001, which is fixedly connected to the mounting bracket 1 and located below the guide channel 8. Inside the fixed frame 1001, a partition 1002 separates the clean water tank 1003 and the wastewater tank 1004. An mounting plate 1016 is fixedly connected to the fixed frame 1001 at the position of the clean water tank 1003. The fixed frame 1001 is located below the guide channel 8. This position design not only provides a stable mounting carrier for the internal components of the fixed frame 1001 and the mounting plate 1016 above, but also allows the wastewater generated during the impurity removal process to flow directly into the guide channel 8 below, avoiding wastewater overflow and pollution. The clean water tank 1003 and the wastewater tank 1004 realize independent partitioning of clean water storage and wastewater temporary storage, effectively preventing water pollution caused by the mixing of clean water and wastewater, improving water resource utilization, and facilitating the subsequent centralized treatment of wastewater in the wastewater tank 1004.

[0020] Furthermore, a drain pipe 1005 is fixedly connected to the front left end of the fixed frame 1001 at the location of the sewage tank 1004, and a filling pipe 1006 is fixedly connected to the upper center of the mounting plate 1016. The drain pipe 1005 can conveniently discharge the sewage temporarily stored in the sewage tank 1004, avoiding the long-term accumulation of sewage in the tank that may produce odors or breed bacteria. The filling pipe 1006 allows staff to add clean water to the clean water tank 1003 without disassembling any parts, effectively ensuring the continuity of the impurity removal process and avoiding the impact of water replenishment on the impurity removal efficiency.

[0021] Furthermore, a centrifugal water pump 1007 is fixedly connected to the upper right side of the mounting plate 1016. An inlet pipe 1008 is fixedly connected to the input end of the centrifugal water pump 1007. The end of the inlet pipe 1008 extends into the interior of the clean water tank 1003, and a filter sleeve 1009 is fixedly connected to the outer side of the end of the inlet pipe 1008. A delivery pipe 1010 is fixedly connected to the output end of the centrifugal water pump 1007. The filter sleeve 1009 can effectively filter out a small amount of floating impurities that may exist in the clean water tank 1003, preventing impurities from entering the interior of the centrifugal water pump 1007 and causing pump blockage or component wear, thus significantly extending the service life of the centrifugal water pump 1007.

[0022] Specifically, the impurity removal component 10 also includes two pipe clamps 1012, both of which are fixedly connected to the upper rear side of the mounting frame 4. A main pipe 1013 is fixedly connected between the two pipe clamps 1012. An elbow 1011 is fixedly connected to the upper right side of the main pipe 1013. The other end of the elbow 1011 away from the main pipe 1013 is fixedly connected to the end of the conveying pipe 1010. The two pipe clamps 1012 can firmly clamp and fix the main pipe 1013, effectively preventing the main pipe 1013 from shifting under the impact of high-pressure water flow or equipment vibration, and ensuring the stability of the clean water conveying channel.

[0023] Furthermore, at least five branch pipes 1014 are fixedly connected to the front side of the main pipe 1013. Several spray heads 1015 are fixedly connected to the bottom of each of the five branch pipes 1014. The branch pipes 1014 can evenly distribute the high-pressure clean water in the main pipe 1013 to each spray position. The spray heads 1015 can convert the clean water into a uniform water mist or water flow, and spray the taro on the mesh conveyor belt 5 from above to clean it thoroughly. This effectively washes away the mud, weeds and other impurities attached to the taro. Combined with the mesh leakage function of the mesh conveyor belt 5, a dual impurity removal effect of "spraying impurity removal + mesh leakage" is formed.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0025] Working principle: First, clean water is injected into the clean water tank 1003 through the filling pipe 1006. The drive source 7 on the front side of the mounting frame 4 is started, and the drive source 7 drives the mesh conveyor belt 5 to rotate. The mesh on the surface of the mesh conveyor belt 5 prepares for subsequent water leakage. After the taro harvester is started, the digging device digs up the taro in the field and transports it to the input end of the mesh conveyor belt 5 of this mechanism. After the taro falls into the conveyor belt, it is blocked by the guide baffle 6 on the surface and moves towards the grain bin of the harvester with the conveyor belt. The guide baffle 6 can prevent the taro from running to both sides due to the bumps of the conveyor belt or piling up with each other during the transportation process. When the first group of taro moves with the conveyor belt to below the spray head 1015, the centrifugal water pump 1007 works to draw clean water from the clean water tank 1003 through the water inlet pipe 1008 at the input end. The filter sleeve 1009 filters weeds, small stones and other impurities in the water to prevent the water pump impeller from being blocked. After the clean water is pressurized by the water pump, The water is transported to the main pipe 1013 through the output pipe 1010 and elbow 1011. The clean water in the main pipe 1013 is evenly distributed to at least five branch pipes 1014 on the front side. Several spray heads 1015 at the bottom of each branch pipe 1014 spray high-pressure water at the same time. The water flows vertically downward to cover the taro on the surface of the conveyor belt. The impact force of the water can wash away the wet soil and fine sand on the surface of the taro. The dirty water after washing seeps downward through the mesh of the mesh conveyor belt 5 and falls into the U-shaped guide channel 8 at the bottom of the installation frame 4. The dirty water flows naturally along the inclined angle of the guide channel 8 to the sewage tank 1004 below, completing the closed loop of "washing impurities and collecting sewage". The dirty water in the guide channel 8 continues to flow into the sewage tank 1004 in the fixed frame 1001. When it is full, the operation can be stopped, the valve of the sewage pipe 1005 can be opened to discharge the sewage into the field drainage ditch. After the discharge is completed, the valve is closed and the operation can continue.
