Description

Technical Field

[0001] This invention patent belongs to the field of taro harvesting technology, specifically relating to an integrated machine for taro harvesting, sorting, and storage. Background Technology

[0002] Taro, cultivated as a staple crop, is an important vegetable and food source with high nutritional and medicinal value, making it a suitable food for all ages. Currently, taro harvesting in my country mainly relies on manual or mechanized methods. On the one hand, manual harvesting is inefficient, and labor costs have been increasing year by year, while taro harvesters on the market generally suffer from low efficiency, resulting in low taro yields and hindering industrialized production. On the other hand, the market demand for taro is exceptionally large, leading to a significant supply shortage. Especially in the last two years, with the improvement of related production technologies, the standardization of taro cultivation and the scientific management have greatly increased taro yields, making the research and application of taro harvesters even more urgent.

[0003] Chinese patent application publication number CN 118202851 A discloses a taro harvesting device, including a frame with a stem and leaf crushing mechanism on the front side of the frame, and a taro conveying mechanism, a soil screening mechanism, and a sorting mechanism mounted on the frame. The multi-functional taro harvester of the above invention harvests taro by first shoveling and crushing the stems and leaves and then digging out the taro. During the harvesting process, it is impossible to harvest and preserve the taro stems and leaves completely, and the use of a shovel for harvesting easily damages the integrity of the taro fruit. Therefore, it is necessary to design an integrated machine for taro harvesting, sorting, and storage to solve the above technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machine for taro harvesting, sorting, and storage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A machine integrating taro harvesting, sorting, and storage includes a frame. Its features include: a drive unit connected to the frame chassis; a drill bit installed on each side of the front end of the frame; a stem-clamping conveyor belt installed inside each drill bit; a soil-sweeping device installed below the middle of the stem-clamping conveyor belt; after the soil-sweeping device cleans the taro's exterior, the taro comes into contact with the stem-cutting blade; a sorting conveyor belt is installed below the stem-cutting blade; a temporary storage area is located on each side of the sorting conveyor belt; an ascending conveyor belt is installed behind each of the two temporary storage areas; the ascending conveyor belt can transport the taro to the taro fruit collection area; and an unloading device is located below the fruit collection area.

[0007] Preferably, the outer sides of the two stem-clamping conveyor belts are covered with sponges, with no gaps between the sponges. The conveyor belts are connected to a motor, and the stepper motor drives the two conveyor belts to rotate in different directions. The taro stems are clamped by the sponges on both sides, causing the taro to move upward along the conveyor belts.

[0008] Preferably, the two drill bits are respectively installed on the outside of the stem clamping conveyor belt. The drill bits are controlled by a motor to move downward. The two drill bits are driven by a stepper motor to penetrate into the soil and rotate, thereby loosening the soil and making it easier to pull out the taro.

[0009] Preferably, the packaging conveyor belt is located below the stem-cutting blade. A DC motor drives the stem-cutting blade to rotate, separating the taro fruit from the taro stem. After passing through the stem-cutting blade, the taro falls onto the packaging conveyor belt. The forward and reverse rotation of the stepper motor below allows the conveyor belt to transport taro in two directions, sending it into a temporary storage area. When one temporary storage area is full, the direction of the stepper motor can be changed to transfer the taro to the empty temporary storage area on the other side, thus improving the taro collection efficiency.

[0010] Preferably, each of the two upward conveyor belts is connected to a stepper motor, and the upward conveyor belt is equipped with a baffle with curved edges. The upward conveyor belt drives the baffle to move along the conveyor belt path, and the baffle carries the taro collected in the temporary storage area to move upward along the conveyor belt and finally fall into the fruit collection area.

[0011] Preferably, the unloading device below the fruit collection area is connected to a stepper motor via a lead screw, and the lead screw is connected to the unloading device via a connecting rod. The stepper motor drives the lead screw to rotate and pushes one end of the connecting rod forward, while the other end connected to the unloading device will lift up, causing the unloading device to open and tilt, thereby achieving the purpose of pouring out all the collected taro.

[0012] Preferably, the stem-leaf separation conveyor belts are located on both sides of the center of the vehicle, and are covered with sponge with no gap between the two sponge pieces. Each of the stem-leaf separation conveyor belts on both sides is connected to a stepper motor, which drives the conveyor belts to rotate.

[0013] Preferably, the stem-leaf separating blade is connected to the motor and located below the stem-pulling device. There is a stem-leaf storage area on each side below the stem-pulling device. At the end of the stem-leaf storage area is a discharge plate, which is connected to a stepper motor via a lead screw. The stem-leaf separating blade is also connected to a stepper motor, which drives the blade to rotate clockwise to separate and cut the stem and leaves. Due to the curvature of the blade, when the stem below is separated, it will fall into the stem-leaf storage area on the left due to inertia, while the leaves will be pushed into the stem-leaf storage area on the right by the stem-pulling device. When the conditions for tilting the stem and leaves are met, the stepper motor will drive the lead screw to rotate and push the baffle outward, thus pushing out the stem and leaves.

[0014] As a preferred technical solution of the present invention, the rising conveyor belt, drill bit, stem cutting blade, stem and leaf separation conveyor belt, stem and leaf separation blade and stem pulling device work together to completely pull the taro out of the soil and completely cut and separate the taro stem, leaves and fruits and store them in different areas.

[0015] The beneficial effects of this invention are as follows: This taro harvester integrates taro picking, sorting, and storage, and is a multi-functional taro harvester that combines picking, sorting, and storage. After the taro is dug up, the surface soil can be removed by a sweeping mechanism, and different parts of the taro can be separated and sorted for collection at the same time. This taro harvester can quickly and completely complete the taro picking process. It has the characteristics of compact structure, small footprint, easy operation, high efficiency, and simple maintenance. It can not only effectively reduce the intensity of manual taro digging and reduce labor costs, but also make full use of the value of each part of the taro. Attached Figure Description

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, the multifunctional taro integrated harvester of the present invention includes a frame 17, a drive unit 1 connected to the frame chassis, a drill bit 2 installed on each side of the front end of the frame, a stem clamping conveyor belt 3 installed on the inner side of each drill bit, a soil sweeping device 4 installed below the middle of the stem clamping conveyor belt, after passing the soil sweeping device comes into contact with the stem cutting blade 5, a sorting conveyor belt 6 is installed below the stem cutting blade, a temporary storage area 7 is installed on each side of the sorting conveyor belt, an ascending conveyor belt 8 is installed behind each of the two temporary storage areas, a baffle 9 is installed on the ascending conveyor belt, which can convey taro to the taro fruit collection area 10, and an unloading device 11 is located below the fruit collection area; after the taro fruit and stems and leaves are separated by the stem cutting blade 5, they are conveyed to the stem and leaf separation conveyor belt 13, after passing the stem and leaf separation blade 12, the stems and leaves are separated by the stem pulling device 14 and collected in the two separate stem and leaf storage areas 15 on the left and right, and an unloading plate 16 is connected to the top by a screw rod.

[0027] Combination Figure 2 The multifunctional taro integrated harvester provided by the present invention uses a drive device 1 to reach the planting location of the taro, and the drill bit 2 is driven by a motor to rotate and extend into the soil, making the soil loose.

[0028] As the two side stem-clamping conveyor belts 3 rotate, the machine moves forward. The gap in the middle of the stem-clamping conveyor belt 3 contacts the stem of the taro. The outside of the stem-clamping conveyor belt 3 is covered with sponge to increase friction. The rotation of the conveyor belt pulls the taro out of the soil and makes it move upward along the stem-clamping conveyor belt 3. When the stem-clamping conveyor belt 3 carries the taro upward, the stem of the taro will come into contact with the soil-sweeping device 4 to clean the soil on the surface of the taro.

[0029] Combination Figure 3 When the stem-clamping conveyor belt 3 carries the taro upwards past the soil-sweeping device 4, the taro stem will come into contact with the stem-cutting blade 5 located on the upper part of the stem-clamping conveyor belt 3, and the taro fruit and stem will be separated.

[0030] The taro stems continue to move along the stem-clamping conveyor belt to the stem-leaf separation conveyor belt 13, while the taro fruits fall onto the packaging conveyor belt 6 under gravity. The packaging conveyor belt 6 then carries the taro fruits into the temporary storage areas on both sides.

[0031] Example 2

[0032] Combination Figure 4Based on Example 1, when the taro stem reaches the highest point of the stem clamping conveyor belt 3, the taro stem contacts the stem-leaf separation conveyor belt 13. Since the stem-leaf separation conveyor belt 13 is covered with a sponge, the taro stem is clamped by friction and moves toward the stem-leaf separation blade 12. When the top of the taro stem contacts the stem-leaf separation blade 12, the taro stem will fall into the left stem-leaf storage area 15 due to inertia. At the same time, the stem-pulling device 14 rotates to the other side, pushing the taro leaves to the right stem-leaf storage area 15. The taro leaves will fall into the stem-leaf storage area 15 due to gravity, thereby achieving the purpose of completely separating the taro stem and leaves and storing them separately in the two sides of the stem-leaf storage area 15.

[0033] Once the stem and leaf storage area 15 is full, the machine will move to the unloading area. Then, the stepper motor will drive the lead screw to rotate, causing the unloading plate 16 to push outward. The taro stems and leaves will push open the hatch of the stem and leaf storage area 15 and then fall into the designated unloading area.

[0034] Example 3

[0035] Combination Figure 5 Based on Example 1, when the taro is conveyed to the temporary storage area 7 by the packaging conveyor belt 6, the rising conveyor belt 8 equipped with baffles will rotate under the drive of the motor. The baffles will carry the taro fruits stored in the temporary storage area 7 from the temporary storage area 7 to the top of the rising conveyor belt 8. Finally, the baffle 9 will flip under the drive of the rising conveyor belt 8, and the taro fruits will fall into the fruit collection area 10 due to gravity.

[0036] Example 4

[0037] Combination Figure 6 When the taro in the fruit collection area 10 is full, the stepper motor drives the lead screw to rotate, causing the connecting rod at one end of the unloading device 11 to move towards the stepper motor, while the other end is lifted upwards. When a certain height is reached, the hatch of the fruit collection area 10 will open under the action of gravity. Since the base of the fruit collection area 10 is lifted at a certain angle, the taro fruits will roll out of the fruit collection area 10 under the action of gravity.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
