Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically a hand-held garlic combine harvester. Background Technology

[0002] Garlic is widely cultivated in Jiangsu, Shandong, and other regions. It has high medicinal value, being rich in allicin and other components, and plays a positive role in preventing cardiovascular diseases and fighting tumors. Its harvest season is concentrated in April and May, which presents challenges such as high labor intensity, low efficiency, and significant damage. Garlic has also been proven to have significant antibacterial and anti-inflammatory properties, making it one of the most antibacterial crops in nature.

[0003] China's garlic planting area has reached 11.96 million hectares, with a total output of 22.34 million tons, ranking first in the world in both planting area and output. However, garlic harvesting has long relied on manual labor, facing a series of problems such as high labor intensity, low efficiency, and high costs. Traditional manual harvesting requires multiple processes, including digging, removing soil, cutting vines, and collecting. The fragile nature of garlic roots and stems and the heavy, sticky soil further increase the difficulty of mechanized operations. Although segmented machinery has been applied in recent years, manual assistance is still needed to complete the subsequent processes, preventing the achievement of full mechanization.

[0004] During my country's industrial transformation, the outflow of young rural laborers has led to a severe labor shortage during the garlic harvest season. Manual harvesting is costly, inefficient, and prone to damage, making it difficult to adapt to the tight harvest schedule and a prominent problem hindering industrial development. Promoting mechanized harvesting is a key path to address labor shortages, improve efficiency, and reduce costs.

[0005] Currently, various garlic harvesting machines have been developed in China, but compared with foreign models, they still lag behind in adaptability and performance, making it difficult to fully meet the diverse planting needs in the country. Therefore, developing efficient, practical, and adaptable garlic harvesting machinery is of great significance for promoting the modernization of garlic production in my country and supporting the sustainable development of the industry.

Detailed Implementation

[0022] like Figure 1-5As shown, a hand-operated garlic combine harvester includes a diesel engine 1, a stalk cutting device 2, a digging shovel 3, a transmission device 4, a drive device 5, a collection basket 6, a reducer 7, and a frame 8. The diesel engine 1 and reducer 7 are mounted on the frame 8 along the forward direction of the frame 8. The stalk cutting device 2 is mounted on the front side of the frame 8, the digging shovel 3 is mounted on the rear side of the stalk cutting device 2, the transmission device 4 is installed inside the frame 8, and the collection basket 6 is mounted on the rear side of the transmission device 4. The output end of the diesel engine 1 drives the stalk cutting device 2 and the reducer 7 through the drive device 5, and the reducer 7 drives the transmission device 4 and the frame 8 forward.

[0023] This utility model has functions such as garlic cutting, digging, separating garlic from soil, conveying garlic cloves, and automatically collecting them into a collection basket 6. First, the stem-cutting device 2 solves the problem of material entanglement that may occur during garlic sprout harvesting, and can also effectively remove obstacles in front of large machinery in farmland operations. Then, the digging shovel 3 is used to dig the garlic out of the soil, and the garlic is conveyed through the conveying device 4 to separate the garlic from the soil. It can fully cover the garlic growing area during harvesting operations, avoiding the need for manual turning of garlic due to garlic falling off, thereby improving the effect and efficiency of garlic harvesting. At the same time, it can prevent the harvester from being disturbed by surrounding weeds and other plants during operation, ensuring the continuity and stability of the operation.

[0024] like Figure 1-5 As shown, the output end of the diesel engine 1 is driven by an engine output shaft 101; the stem-cutting device 2 includes a pulley 201 mounted on a pulley shaft, a stem-cutting frame 2011 fixed to the front side of the frame 8, a drive shaft 204 and a cutter shaft 209 rotatably mounted on the stem-cutting frame 2011, a bevel gear set 205 used to connect the drive shaft 204 and the cutter shaft 209, a crushing cutter 208 mounted on the cutter shaft 209, and a straw-supporting stalk 206 mounted in front of the crushing cutter 208. The straw-supporting stalk 206 is fixed to the stem-cutting frame 2011. A pulley 203 is mounted on the drive shaft 204, and the pulley 203 is connected to the pulley 201 by a drive belt. The bottom end of the cutter shaft 209 is provided with a stem-cutting cutter 207, and the bottom of the stem-cutting frame 2011 is equipped with a depth-limiting wheel 2010. In this embodiment, during the forward movement of the frame 8, the depth-limiting wheel 2010 rolls forward along the ground. The supporting stalk 206 first inserts into the garlic stalk, and the diesel engine 1 outputs power. The diesel engine 1 drives the pulley shaft to rotate through the transmission device 5. The pulley shaft transmits power to the transmission shaft 204 through the pulley 201, the transmission belt 202, and the pulley 203. The transmission shaft 204 further transmits power to the cutter shaft 209 through the bevel gear set 205, thereby driving the stem-cutting cutter 207 and the crushing cutter 208 to rotate at high speed to cut off the garlic stalk, so that the garlic is separated from the stalk.

[0025] like Figure 1-5 As shown, the garlic stalks 206 are multiple L-shaped stalks with gaps between adjacent stalks. In this embodiment, during the forward movement of the vehicle frame 8, the problem of garlic stalks getting tangled is solved by inserting them into the gaps, which also effectively clears obstacles in front of large machinery in agricultural operations.

[0026] like Figure 1-5 As shown, the bevel gear set 205 includes a driving bevel gear fixed on the transmission shaft 204 and a driven bevel gear fixed on the tool shaft 209. The driving bevel gear meshes with the driven bevel gear. In this embodiment, the power on the transmission shaft 204 is transmitted to the tool shaft 209 through the meshing of the driving bevel gear and the driven bevel gear.

[0027] like Figure 1-5 As shown, a pulley seven is provided on the pulley shaft; the transmission device 5 includes a pulley three 501 fixed on the engine output shaft 101, a transmission belt three 503 connecting pulley seven and pulley eight, a pulley four 504 provided on the input shaft of the reducer 7, a transmission belt two 502 connecting pulley three 501 and pulley four 504, a reducer output shaft provided at the output end of the reducer 7, a drive sprocket one 702 provided on the reducer output shaft, a transmission shaft five 507 and a drive shaft rotatably mounted on the frame 8, a sprocket three 506 and a pulley five 508 provided on the transmission shaft five 507, and a transmission chain one 505 connecting the drive sprocket one 702 and sprocket three 506; in this embodiment, the diesel engine 1 outputs... Power is transmitted through pulleys 3 501 and 7 mounted on the engine output shaft 101. Pulley 7 transmits power to pulley 8 via transmission belt 3 503, causing the pulley shaft and pulley 1 201 to rotate, thereby driving the stem cutting device 2. Simultaneously, pulley 3 501 transmits power to pulley 4 504 via transmission belt 2 502. Pulley 4 504 transmits power to the reducer output shaft via the input shaft of reducer 7. The reducer output shaft drives the drive shaft 5 507 to rotate via drive sprocket 1 702, transmission chain 1 505, and sprocket 3 506. Since the large traveling wheels of the frame 8 are mounted on the drive shaft 5 507, the rotation of the drive shaft 5 507 drives the large traveling wheels of the frame 8 to rotate, providing a power source for the frame 8 and enabling the frame to move forward.

[0028] like Figure 1-5As shown, the reducer output shaft is equipped with a second drive sprocket, and the drive shaft is equipped with a sixth pulley 5010. The fifth pulley 508 and the sixth pulley 5010 are connected by a fourth transmission belt 509. The transmission device 4 includes a second drive shaft 403, a third drive shaft 404, and a fourth drive shaft 407 that are parallel to and rotatably mounted on the frame 8. A first sprocket 402 and a fourth sprocket 5012 are mounted on the second drive shaft 403, a second sprocket 406 is mounted on the fourth drive shaft 407, and a transmission chain 401 connects the first sprocket 402 and the second sprocket 406. The third drive shaft 404 is located between the second drive shaft 403 and the fourth drive shaft 407, and a cam 405 is mounted on the third drive shaft 404. The fourth sprocket 5012 and the second drive sprocket are connected by a second transmission chain 5011. In this embodiment, the reducer output shaft transmits power from the diesel engine 1 to the transmission shaft 403 via the second drive sprocket, the second transmission chain 5011, and the fourth sprocket 5012. The second transmission shaft 403 then transmits power to the first sprocket 402, realizing the output function of the transmission device 4 and conveying the garlic to the collection basket 6. At the same time, the fifth transmission shaft 507 drives the third transmission shaft 404 to rotate via the fifth pulley 508, the fourth transmission belt 509, and the sixth pulley 5010. The third transmission shaft 404 drives the cam 405 to rotate at a constant speed. The rotation of the cam 405 causes the transmission chain 401 to vibrate, thereby causing the soil to fall off and completing the separation of the garlic from the soil. The front end of the digging shovel 3 is lower than the lowest end of the transmission chain 401, and the rear end of the digging shovel 3 extends upward at an angle to above the lowest end of the transmission chain 401.
