Description

Technical Field

[0001] The utility model relates to the technical field of crop harvesting devices, in particular to a small harvester capable of improving the taro harvesting efficiency. Background Art

[0002] Taro is a nutritious food suitable for all ages. At the same time, its starch granules are small and easy to digest, making it an important vegetable and food crop.

[0003] With the large-scale development of taro cultivation, the harvesting mode mainly relying on manual labor can no longer meet the development needs. The harvesting process of taro mainly includes the cutting of stems, the excavation and soil screening of taro, and the separation and screening of mother and son taros. The existing taro harvesting machines mainly solve the excavation process of taro, while the collection after taro excavation and the separation process of mother and son taros still rely on manual labor, which is time-consuming and laborious, and there are many problems such as low mechanization degree of taro harvesting and difficulty in handling stems and leaves. Content of the Utility Model

[0004] The utility model aims to at least improve one of the technical problems existing in the prior art. For this purpose, the utility model provides a small harvester capable of improving the taro harvesting efficiency.

[0005] The small harvester capable of improving the taro harvesting efficiency according to the first aspect embodiment of the utility model includes:

[0006] A frame body;

[0007] An unearthed mechanism fixedly installed at the bottom of the frame body;

[0008] A stem and leaf crushing mechanism fixedly installed on the frame body for crushing taro stems and leaves;

[0009] A transportation mechanism fixedly installed on one side of the stem and leaf crushing mechanism;

[0010] A mother and son taro separation mechanism fixedly arranged on the frame body far away from the unearthed mechanism. The taro at the bottom of the stem and leaf crushing mechanism is transported above the mother and son taro separation mechanism through the transportation mechanism, facilitating the separation operation of mother and son taros.

[0011] The small harvester capable of improving the taro harvesting efficiency according to the embodiment of the utility model can replace manual labor, reduce labor intensity, and improve the taro harvesting efficiency; the utility model can mechanically separate mother and son taros through the mother and son taro separation mechanism, avoiding later manual processing and improving work efficiency; at the same time, it also meets the current trend of agricultural production mechanization, scientificization, and efficient utilization, and has a relatively wide application prospect.

[0012] In a possible implementation manner of the first aspect, the unearthed mechanism includes an aluminum plate and a harrow plate fixedly connected, and the aluminum plate is fixedly connected to the main body of the frame.

[0013] In a possible implementation manner of the first aspect, the stem and leaf crushing mechanism includes a first motor, a first drive shaft, a cutting blade group, and an arc-shaped outer cover. The first motor is fixedly installed on the main body of the frame, the main body of the frame is coaxially connected to the first motor, a cutting blade group is fixedly installed at the end of the first drive shaft away from the first motor, and an arc-shaped outer cover in the shape of a "C" is fixedly installed on the main body of the frame near the periphery of the cutting blade group. A notch for the taro stems and leaves to enter is provided in the arc-shaped outer cover.

[0014] In a possible implementation manner of the first aspect, the transportation mechanism includes a second motor, two second drive shafts, a chain, a strip-shaped mounting plate, and a partition. The second motor is fixedly installed on one side of the main body of the frame, the two second drive shafts are respectively obliquely installed at the bottom end and the top end of the main body of the frame through bearings, the second drive shaft at the top end is fixedly connected to the second motor, the two second drive shafts are connected by chain drive, a number of strip-shaped mounting plates are provided on the chain, and partitions are arranged at intervals on the strip-shaped mounting plates. By driving the second drive shaft to rotate through the second motor, the taro is conveyed from the bottom end to the top end of the main body of the frame.

[0015] In a possible implementation manner of the first aspect, the mother and son taro separation mechanism includes a third motor, a belt, a driven wheel, a stripping member, a spiral blade, and a sleeve. The third motor is fixedly installed on the main body of the frame, a roller is installed at the output end of the third motor, the roller is connected to the driven wheel through a belt, the driven wheel is fixedly connected to a rotating shaft equipped with a spiral blade, the spiral blade is located inside the sleeve, and a number of stripping members are distributed on the side wall of the sleeve for separating the mother and son taros. When the taro falls into the sleeve, the third motor drives the spiral blade through the synchronous belt composed of the belt and the driven wheel, so that the spiral blade rotates downward, and the taro moves downward along the rotation direction of the spiral blade. At the same time, affected by the centrifugal force, the taro moves towards the cylinder wall. The stripping member with a human-like tiger mouth design on the cylinder wall is in the shape of a "U" groove, which can effectively hold the son taro and give the son taro a force opposite to the movement direction. At this time, the mother taro still maintains the trend of moving downward in a spiral manner, and the son taro is separated from the mother taro along with the spiral blade and moves downward into the collection box.

[0016] In a possible implementation manner of the first aspect, the first drive shaft adopts an aluminum drive shaft, which is light in texture while ensuring the stiffness and strength required for a certain drive shaft. While ensuring the normal operation of the function, it reduces the load of the function module, thus ensuring a higher rotation speed and making the function module work more smoothly.

[0017] In a possible implementation of the first aspect, the cutting blade group is formed by splicing two manganese steel blades in a staggered manner up and down, which increases the crushing area and improves the efficiency and degree of crushing. The manganese steel material ensures the sharpness of the cutter while ensuring the quality of the cutter.

[0044] It should be noted that the unearthed mechanism 200 includes an aluminum plate and a rake plate fixedly connected, and the aluminum plate is fixedly connected to the frame body 100. This structure reduces the resistance to entering the soil and has strong soil-breaking ability, so as to smoothly shovel out the taro. Due to the specific growth characteristics of taro, that is, the daughter taro only grows around the mother taro, and the depth of the mother taro is determined during sowing, so the approximate depth of the taro in the soil can be determined according to the height of the ridge, ensuring that it can be smoothly dug out without damaging the taro.

[0045] It should be noted that the stem and leaf crushing mechanism 300 includes a first motor 310, a first drive shaft 320, a cutting blade group 330 and an arc-shaped outer cover 340. The first motor 310 is fixedly installed on the frame body 100, and the frame body 100 is coaxially connected to the first motor 310. A cutting blade group 330 is fixedly installed at the end of the first drive shaft 320 far from the first motor 310, and an arc-shaped outer cover 340 in the shape of a C is fixedly installed on the frame body 100 near the periphery of the cutting blade group 330.

The taro moves downward along the rotation direction of the spiral blade 550. At the same time, affected by the centrifugal force, the taro moves toward the cylinder wall. The stripping member 540 with a design imitating the human tiger's mouth on the cylinder wall is in the shape of a U-shaped groove, which can effectively hold the child taro and give the child taro a force opposite to the movement direction. At this time, the parent taro still maintains the tendency to move downward in a spiral manner, and the child taro is separated from the parent taro along with the trend and moves downward along the spiral blade 550 into the collection box.

[0048] It should be noted that when the transportation mechanism 400 lifts the taro to the top, at this time the taro is located above the sleeve 560, which is convenient for the taro to fall into the parent and child taro separation mechanism 500 for separation.

[0049] It should be noted that the first drive shaft 320 is made of an aluminum drive shaft, which is light in texture while ensuring the stiffness and strength required for a certain drive shaft.
