[0029] To better understand the purpose, structure, and function of this invention, a garlic harvester of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1 As shown, the garlic harvester in this embodiment includes a frame 1, a power unit 2, and a seat 9. Various mechanical components are connected to the frame 1. The power unit 2 provides power to the entire garlic harvester. The frame 1 is equipped with a connecting mechanism 3, which is fixedly connected to the frame 1. The power unit 2 is equipped with a connecting frame 4, which is detachably connected to the power unit 2. A shaft 5 is located inside the connecting frame 4 and can rotate within it. The connecting frame 4 includes a first fixing plate 401, a connecting sleeve 402, a connecting frame 403, and a second fixing plate 404. The connecting sleeve 402 is inclined to the first fixing plate 401. Figure 5 As shown, if the connecting sleeve 402 is taken as the horizontal reference plane, the first fixing plate 401 should be tilted to the right relative to the connecting sleeve 402. The connecting frame 403 is fixed to the first fixing plate 401, and the second fixing plate 404 is fixed to the connecting frame 403. That is, the connecting frame 403, the second fixing plate 404, and the first fixing plate 401 have the same tilt angle. The connecting sleeve 402 is connected to the connecting mechanism 3 via a shaft 5. The connecting sleeve 402 is fixed to the connecting frame 4, which is fixed to the power unit 2. The connecting mechanism 3 is fixed to the frame 1. Thus, the connection between the power unit 2 and the frame 1 is achieved through the connection between the connecting sleeve 402 and the connecting mechanism 3. The power unit 2 is equipped with a gear shift mechanism 203, which has a shift lever 2031. Figure 3 , 4As shown, the gear shift mechanism 203 on the power unit 2 is located above the connecting frame 4. Since the connecting sleeve 402 of the connecting frame 4 is inclined to the first fixing plate 401, the connection angle between the connecting frame 4 and the frame 1 is moved downward. As a result, the angle of the gear shift mechanism 203 located above the connecting frame 4 toward the seat 9 is also moved downward. This allows the shift lever 2031 located on the gear shift mechanism 203 to pass through the seat 9 without contacting the seat 9.

[0032] In this embodiment, the power unit 2 includes a walking mechanism 201, an engine 202, a gear shift mechanism 203, and a transmission mechanism 204. The walking mechanism 201 propels the entire garlic harvester to move forward or backward. The engine 202 provides the power required by the garlic harvester. The gear shift mechanism 203 is used to change the direction and speed of movement of the walking mechanism 201. The transmission mechanism 204 is used to transmit the power of the engine 202 to other mechanisms. The engine 202 is installed in the middle of the walking mechanism 201. The gear shift mechanism 203 is installed on the engine 202. The transmission mechanism 204 is also installed on the engine 202.

[0033] like Figure 6 As shown, in this embodiment, a conveying mechanism 6 is installed below the frame 1. By installing the conveying mechanism 6 below the frame 1, the conveying mechanism 6 shakes off the soil from the garlic cloves and gradually gathers the garlic cloves after shaking off the soil, conveying them to the tail of the frame 1. The conveying mechanism 6 includes a second sprocket 601, a conveying roller 602, a rotating shaft 603, and a fixed frame 604. The second sprocket 601 is used to drive the power on the drive shaft 11 and transmits the power to each rotating shaft 603. The rotating shaft 603 then drives the conveying roller 602 to rotate, completing the conveying and soil-shaking steps of the garlic. The fixed frame 604 is provided with a rotating shaft 603, a conveying roller 602 is provided on the rotating shaft 603, and a second sprocket 601 is provided on the rotating shaft 603.

[0034] In this embodiment, the frame 1 is provided with a garlic collecting mechanism 7, which is used to shovel garlic out of the soil and transfer it to the conveying mechanism 6. The garlic collecting mechanism 7 includes a first swing arm 701, a second swing arm 702, and a garlic collecting blade 703. The first swing arm 701 and the second swing arm 702 are movably connected, and the second swing arm 702 is fixedly connected to the garlic collecting blade 703. The first swing arm 701 is connected to the eccentric wheel 12 on the drive shaft 11. The first swing arm 701 drives the second swing arm 702 and the garlic collecting blade 703 to perform garlic shoveling actions through the power on the eccentric wheel 12.

[0035] In this embodiment, the frame 1 is provided with a steering mechanism 8, which includes a steering wheel 801, a steering gear 802, and wheels 803. The steering gear 802 is equipped with the steering wheel 801 and wheels 803. The steering mechanism 8 is used to control the direction of the entire garlic harvester, as well as to control the lifting and lowering of the conveying mechanism 6 and the garlic collecting mechanism 7. The operator controls the steering wheel 801 to turn, and the steering wheel 801 controls the wheels 803 to rotate through the steering gear 802.

[0036] like Figure 2 As shown, in this embodiment, a seat 9 is provided on the frame 1, and a clutch mechanism 10 is provided on the frame 1. The clutch mechanism 10 is used to control the power transmission on the drive shaft 11. The frame 1 is provided with a drive shaft 11, and a pulley 16 is provided on the drive shaft 11. One end of the drive shaft 11 is connected to the clutch mechanism 10, and the other end is connected to the eccentric wheel 12. A first sprocket 1101 is installed on the drive shaft 11. The power unit 2 transmits power to the pulley 16. When the clutch mechanism 10 is engaged, the pulley 16 transmits power to the drive shaft 11. The drive shaft 11 then drives the eccentric wheel 12 and the first sprocket 1101 to rotate; the first sprocket 1101 and the second sprocket 601 are connected by a chain 13; the chain 13 connects the first sprocket 1101 and the second sprocket 601, transmitting the power of the first sprocket 1101 to the second sprocket 601; the first swing arm 701 is connected to the eccentric wheel 12, so that the first swing arm 701 is affected by the power of the eccentric wheel 12, thus performing regular movements.

[0037] In this embodiment, the number of conveyor rollers 602 is 4-6; the length of the conveyor rollers 602 is 0.84-1.26 meters. By changing the number of conveyor rollers and the length of the conveyor rollers, the conveying mechanism of the garlic harvester can be adapted to more working scenarios.

[0038] In this embodiment, the drive shaft 11 is movably connected to the pulley 16, and the transmission mechanism 204 is connected to the pulley 16 via the belt 14. The transmission mechanism 204 in the power unit 2 transmits power to the pulley 16 via the belt 14. When the clutch mechanism 10 is not engaged, the pulley 16 does not drive the drive shaft 11 to rotate.

[0039] The clutch mechanism 10 in this embodiment includes a control lever 1001, an elastic mechanism 1002, and a locking mechanism 1003. The locking mechanism 1003 is connected to the control lever 1001 and the elastic mechanism 1002. The clutch mechanism 10 controls whether the locking mechanism 1003 is engaged by moving the control lever 1001. The elastic mechanism 1002 provides a continuous thrust when the locking mechanism 1003 is engaged, ensuring the stability of the engagement of the locking mechanism 1003.

[0040] In this embodiment, the first fixing plate 401 is connected to the power unit 2, the second fixing plate 404 is connected to the frame 1, and the power unit 2 and the frame 1 are connected by the connecting frame 4. The first fixing plate 401 is connected to the power unit 2, and the second fixing plate 404 is connected to the frame 1, so that the power unit 2 and the frame 1 are connected by the connecting frame 4.

[0041] In this embodiment, the power unit 2 provides power to the entire garlic harvester. The transmission mechanism 204 on the power unit 2 transmits power to the pulley 16. The power on the pulley 16 is controlled by the clutch mechanism 10. When the clutch mechanism 10 is engaged, the power is transmitted from the pulley 16 to the drive shaft 11. After receiving the power, the drive shaft 11 drives the first sprocket 1101 and the eccentric wheel 12 to rotate. The first sprocket 1101 transmits power to the second sprocket 601, which in turn transmits power to the conveying mechanism 6. The conveying mechanism 6 performs conveying and soil shaking operations. The eccentric wheel 12 transmits power to the first swing arm 701, which drives the second swing arm 702 and the garlic harvesting blade 703 to perform garlic shoveling operations.

[0042] This utility model, by installing an inclined connecting bracket 4, allows the upward tilt angle of the gear shift mechanism 203 of the power unit 2 to decrease, thereby enabling the shift lever 2031 in the gear shift mechanism 203 to extend normally under the seat and through to the front of the seat 9 for normal gear shifting. It also prevents the shift lever 2031 from being bent, which could cause mis-shifting during the gear shifting process.

[0043] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
