Description

Technical Field

[0001] This utility model relates to the field of taro cultivation technology, and in particular to a small taro harvesting device. Background Technology

[0002] Taro is typically harvested 6-8 months after planting, with the exact timing varying depending on the variety and climate. When the leaves at the base of the plant begin to yellow and wither, and the petioles droop, it indicates that the underground tubers have matured. Watering should be stopped 7-10 days before harvest to allow the soil to dry appropriately. On a sunny day, use a shovel or rake to dig dig slanted downwards about 30 cm around the plant. After lifting the entire plant, carefully shake off any attached soil. Taro sap contains calcium oxalate crystals, which may cause itching upon skin contact; therefore, large-scale cultivation now often uses machinery for harvesting.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0023] like Figure 1-5As shown, a small taro harvesting device includes a mounting bracket 1 with a traction component 6 installed at one end. The traction component 6 can be installed on a tractor and moved in the taro field for harvesting by the tractor traction device. The mounting bracket 1 is rotatably connected to a conveying component and a support wheel 4. A screen plate 5 is fixedly connected to the rear side of the mounting bracket 1 at an incline. Multiple air jets 24 are fixedly connected to the upper rear side of the mounting bracket 1. An air supply component is fixedly connected to one end of the air jet 24. A bearing 25 is fixedly connected to one end of the air jet 24. A cleaning sleeve 18 is fixedly connected to the movable end of the bearing 25. A cleaning brush 23 is fixedly connected to the outside of the cleaning sleeve 18. Multiple ventilation slots 19 are opened on the side wall of the cleaning sleeve 18. The mounting bracket 1 is slidably connected to a vibrating plate 7 at one end, and multiple shovels 8 are fixedly connected to the lower end of the vibrating plate 7; When the device moves, the inclined shovel 8 inserts into the soil to excavate the taro. It employs a two-stage digging shovel design with shovel face angles of 20° and 25°, and a blade angle of 45° to reduce digging resistance and accommodate the planting depth of the taro. Each shovel is 60mm wide, and the spacing between adjacent shovels is 24mm. The maximum force it can withstand is 45.516 MPa, meeting design requirements, and it also possesses high strength, wear resistance, and corrosion resistance. The taro is then squeezed and moved backward, falling onto the conveyor assembly and being transported above the inclined sieve plate 5. The sieve plate 5 is higher in the front and lower in the back, and because the device moves up and down and vibrates as it moves through the field, the taro rolls down on the sieve plate 5. At the same time, the cleaning sleeve 18 above rotates, which drives multiple cleaning brushes 23 to rotate and clean the taro. The rotation direction of the cleaning brushes 23 is opposite to the direction of movement of the taro, which can brush off more soil. In addition, the air jet vent 24 installed in the cleaning sleeve 18 can spray high-speed gas downward, which works with the cleaning brushes 23 to remove the soil on the taro and clean it simultaneously.

[0024] In this embodiment, the conveying assembly includes a conveyor belt component 10 and a plurality of drive shafts 11. The drive shafts 11 are rotatably connected inside the mounting bracket 1. The conveyor belt component 10 is drive-connected to both ends of the plurality of conveyor belt components 10. The conveyor belt component 10 is preferably a plate chain, which can support and transport taro. There are sprockets on both sides of the drive shaft 11, which can drive the chains on both sides of the conveyor belt component 10.

[0025] In this embodiment, a drive motor 3 is fixedly connected above the mounting bracket 1. One end of the drive shaft 11 on one side is fixedly connected to a sprocket set 12, one end of the cleaning sleeve 18 on one side is fixedly connected to a sprocket set 2 13, and one end of the cleaning sleeve 18 on the other side is fixedly connected to a synchronous sprocket 14. The two ends of the sprocket set 12 are respectively connected to the power output end of the drive motor 3 and the sprocket set 2 13 via chain transmission. The sprocket set 2 13 and the synchronous sprocket 14 are fixedly connected by a chain. The sprocket set 12, the sprocket set 2 13 and the synchronous sprocket 14 are rotatably connected to the mounting bracket 1. When the drive motor 3 starts, it can drive the sprocket set 12, the sprocket set 2 13 and the synchronous sprocket 14 to rotate simultaneously through multiple chains, thereby driving the conveying component and the cleaning sleeve 18 to rotate to realize the transportation and cleaning of taro.

[0026] In this embodiment, the air supply assembly includes a fan 2 and a diversion pipe 17. The fan 2 is fixedly connected to the upper end of the mounting bracket 1, and the diversion pipe 17 is fixedly connected to the air outlet of the fan 2. The air outlet of the diversion pipe 17 is fixedly connected to the jet nozzle 24. The fan 2 can spray high-speed gas from the jet nozzle 24 through the diversion pipe 17 for cleaning.

[0027] In this embodiment: when the device moves, the inclined shovel plate 8 inserts into the soil to dig out the taro. A two-stage digging shovel design is adopted, with shovel face inclination angles of 20° and 25°, and a blade inclination angle of 45°, to reduce digging resistance and accommodate the planting depth of the taro. Each shovel is 60mm wide, and the spacing between adjacent shovels is 24mm. The maximum force it can withstand can reach 45.516Mpa, meeting design requirements, and it also possesses high strength, wear resistance, and corrosion resistance. The taro is then squeezed and moved backward, falling onto the conveyor assembly and being transported above the inclined sieve plate 5. The sieve plate 5 is higher in the front and lower in the back, and because the device moves up and down and vibrates as it moves in the field, the taro rolls down on the sieve plate 5. At the same time, the cleaning sleeve 18 above rotates, which can drive multiple cleaning brushes 23 to rotate and clean the taro. The rotation direction of the cleaning brushes 23 is opposite to the direction of movement of the taro, which can brush off more soil. The air jet vent 24 installed in the cleaning sleeve 18 can spray high-speed gas downward, which works with the cleaning brushes 23 to remove the soil on the taro and clean it simultaneously. When the drive motor 3 starts, it can simultaneously drive the sprocket group 12, sprocket group 2 13 and synchronous sprocket 14 to rotate through multiple chains, thereby driving the conveying component and cleaning sleeve 18 to rotate to realize the transportation and cleaning of taro. The optimal device operates at a speed of 1.2 m / s, with a linear chain speed of 1.6 m / s, achieving a harvesting efficiency of 3.11 mu / hour, which is about 15 times higher than the manual harvesting efficiency of 0.2 mu / hour.

A spring 16 is fixedly connected to one end of the vibration plate 7 and the limit plate 15. The protective baffle 20 can prevent soil from falling onto the cam 22 and the bottom motor 21. When the bottom motor 21 drives the cam 22 to rotate, it can work with the spring 16 to squeeze the vibrating plate 7 to move back and forth, which can more effectively shovel the taro out of the soil and prevent the device from getting stuck.

[0029] In this embodiment, a protective cover 9 is fixedly connected to the outside of the limiting plate 15. The protective cover 9 can prevent the stems and leaves of weeds in the field from getting stuck in the spring 16.
