Description

Technical Field

[0001] This invention relates to the field of garlic scape harvesting machinery technology, and in particular to a garlic scape harvester with vibration function. Background Technology

[0002] Garlic is rich in nutrients, containing allicin, minerals, and vitamins. It possesses antibacterial and anti-cancer health benefits, and enjoys strong domestic and international demand. my country is the world's largest producer and exporter of garlic. Garlic scapes, also known as garlic shoots or garlic sprouts, consist of the scape bud and stalk. They are one of China's highest-quality vegetables with the longest storage and supply period, boasting a unique flavor and rich nutrition, making them highly popular among consumers. Currently, research on mechanized garlic scape harvesting is still in its early stages. Garlic scape harvesting is time-sensitive, typically needing to be completed 15-20 days before the garlic bulb harvest; otherwise, the quality of the scapes and the yield of the garlic will be affected. For a long time, garlic scape harvesting has relied mainly on manual labor, which is labor-intensive, inefficient, and hampered by rural labor shortages and rising labor costs, severely restricting the industry's development. As an economic byproduct of the garlic industry, mechanized garlic scape harvesting is a crucial step in the overall mechanization of the garlic industry. However, due to inconsistent garlic planting standards and complex plant growth, mechanized harvesting requires taking into account both the integrity of the garlic scapes and the later growth of the plants, which is technically challenging and has become a key bottleneck restricting the development of the garlic scape and garlic industry. Summary of the Invention

[0003] The purpose of this invention is to provide a garlic scape harvester with vibration function to solve the technical problems of high damage rate to garlic plants, high rate of missed scapes, and easy breakage of scapes in existing garlic scape harvesters.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a garlic scape harvester with vibration function, including a walking frame, on which a scape clamping device, a vibration device, a scape pulling device and a collection box are arranged sequentially from front to back, and a control system is also provided on the walking frame; the scape clamping device is located at the front end of the walking frame and installed vertically to the ground, the vibration device is located above the walking frame and above and behind the scape clamping device, and the scape pulling device is located in the middle of the walking frame and below the vibration device, installed at an inclined angle on the horizontal plane, and the scape pulling device is connected to the vibration device and vibrates synchronously with the vibration device; The garlic scape clamping device is used to clamp the garlic scape from the root of the garlic plant. The vibration device is used to make the garlic scape pulling device generate periodic eccentric vibration. The garlic scape pulling device is used to clamp and pull out the garlic scape and transport it backward. The collection box is installed at the rear end of the walking frame to collect the pulled-out garlic scape. The control system is electrically connected to the garlic scape clamping device, the vibration device, and the garlic scape pulling device respectively.

[0005] Furthermore, the garlic shoot clamping device includes a connecting frame, a garlic shoot clamping wheel, a divider, and a protective plate; the garlic shoot clamping wheel is a pair of relatively rotating discs with parallel axes and is mounted on the side walls of the connecting frame; the divider is fixed to the end of the connecting frame and is used to allow the garlic plant to enter the garlic shoot clamping device; the protective plate is mounted on the side walls of the connecting frame; the rear end of the garlic shoot clamping wheel is connected to the garlic shoot extraction device via a telescopic universal joint coupling to transmit rotational power.

[0006] Furthermore, the connecting frame is fixedly installed to the front end of the walking support by U-bolts.

[0007] Furthermore, the vibration device includes a drive shaft, an eccentric bushing, a U-shaped plate, a bearing seat, and a third servo motor; the eccentric bushing is fixed on the drive shaft and connected to the drive shaft via a keyway, the drive shaft is connected to the U-shaped plate via the bearing seat, and the third servo motor is used to drive the drive shaft to rotate, thereby causing the vibration device to generate periodic eccentric vibration.

[0008] Furthermore, the vibration device is fixedly installed above the traveling frame via a vertical bearing seat.

[0009] Furthermore, the bolting device includes multiple bolting components arranged along the width of the frame. Each bolting component includes two sets of belt conveyor mechanisms arranged side by side. Each set of belt conveyor mechanisms includes a connecting plate. The connecting plate is provided with a front synchronous pulley and a rear synchronous pulley. The front synchronous pulley and the rear synchronous pulley are connected by a synchronous belt drive. The synchronous belts on opposite sides of the two sets of belt conveyor mechanisms are in contact with each other for clamping the garlic scapes.

[0010] Furthermore, the connecting plate is also provided with a floating clamping device located inside the synchronous belt. The floating clamping device includes a baffle, a spring set on the baffle, a clamping frame set at the end of the spring, and a clamping wheel rotatably set on the clamping frame. The two clamping wheels respectively abut against the inner side of the synchronous belt on the opposite side of the two sets of belt conveyor mechanisms.

[0011] According to the above technical solution, the beneficial effects of the present invention are: 1. This invention employs an eccentric bushing fixed to a transmission shaft, driven by a servo motor to generate periodic eccentric vibration. This vibration is transmitted to the bolting working parts through a rigid connection between a U-shaped plate and the bolting device, causing the bolting device to vibrate continuously during clamping and bolting. This vibration causes the garlic scape to sway slightly while clamped, effectively reducing the adhesion between the garlic scape and the pseudostem, thereby reducing the pulling force required for bolting, preventing garlic scape breakage due to excessive pulling force, and reducing the bolting rate.

[0012] 2. The eccentric bushing of this invention adopts a replaceable structure, allowing for flexible adjustment of the vibration amplitude by selecting eccentric bushings with different degrees of eccentricity. This design enables the machine to select an appropriate vibration amplitude based on different varieties and growth conditions of garlic plants, avoiding insufficient auxiliary effect due to too little vibration or plant damage due to too much vibration, thus improving the machine's adaptability to different field conditions.

[0013] 3. This invention uses a control system to control the servo motor of the vibration device, enabling independent adjustment of the vibration frequency. Operators can adjust the vibration frequency in real time according to the actual field conditions, matching the vibration frequency with the bolting speed and the overall machine forward speed, ensuring coordinated optimization of various working parameters, thereby maximizing bolting efficiency while minimizing damage.

[0014] 4. The vibration device of this invention operates continuously during the scape clamping and bolting processes, working in synergy with the flexible clamping of the scape clamping device and the floating clamping of the bolting device. Vibration slightly straightens and loosens the garlic scape while it is clamped, facilitating accurate clamping and root detachment by the scape clamping device, while simultaneously enabling the bolting device to stably clamp the upper part for lifting. This synergistic effect effectively reduces scape leakage due to clamping deviation and damage to the garlic scape caused by uneven bolting resistance, achieving low-damage, high-efficiency garlic scape harvesting.

[0015] 5. In this invention, the bolting device, vibration device, and bolt-pulling device are arranged sequentially from front to back on the walking frame, forming a clear sequential coordination relationship between the devices. The vibration device is located between the bolting device and the bolt-pulling device, and the fixing method of the U-shaped plate and the bearing seat ensures vibration stability, enabling the whole machine to maintain stable operation in the field, reducing mechanical wear caused by uneven vibration transmission, and extending the service life of the whole machine.

[0021] like Figure 1-5 As shown, a garlic scape harvester with vibration function includes a walking frame 2, on which a scape clamping device 5, a vibration device 4, a scape pulling device 1, and a collection box 6 are arranged sequentially from front to back.

[0022] The traveling frame 2 is equipped with traveling wheels 21 at its bottom. The traveling drive is provided by a first servo motor 22, and the steering is controlled by a second servo motor 23 in conjunction with a reducer. The traveling frame 2 also has a control system 3, which is electrically connected to the garlic shoot clamping device 5, the vibration device 4, and the garlic shoot extraction device 1, respectively, and is used to adjust the extraction speed and vibration parameters. A collection box 6 is installed at the rear end of the traveling frame 2 to collect the extracted garlic shoots.

[0023] The garlic scape clamping device 5 includes a connecting frame 55, a clamping wheel 51, a divider 52, a protective plate 53, and U-bolts 56. The divider 52 is fixed to the front end of the connecting frame 55 by bolts, and the protective plate 53 is installed on the outer wall of the connecting frame 55. When the garlic scape harvester moves forward, the divider 52 and the protective plate 53 guide the garlic plants and gather the leaves in sequence, so that the garlic plants are fed into the area of ​​the clamping wheel 51 in an orderly manner. The clamping wheel 51 is a pair of relatively rotating discs with parallel axes and is installed on the side walls of the connecting frame 55. The discs are about 20cm above the ground and have a gap of about 7mm. This gap enables flexible clamping and separation of the garlic scapes, while the gathering effect of the protective plate 53 can reduce leaf damage. The rear end of the clamping wheel 51 is connected to the drive shaft 41 of the bolting device 1 via a telescopic universal joint coupling 54 to transmit rotational power; while the connecting frame 55 is fixedly installed on the 50×50mm square steel at the front end of the walking frame 2 by U-bolts 56 and installed vertically to the ground to ensure that the clamping wheels 51 are at the same height, and to achieve adaptive adjustment of clamping height and clamping gap by means of this installation structure.

[0024] The vibration device 4 is located above the walking frame 2 and above and behind the bolting device 5. It includes a drive shaft 41, an eccentric bushing 44, a U-shaped plate 43, a bearing seat 45, and a third servo motor 42. The eccentric bushing 44 is fixed to the drive shaft 41 and connected to the drive shaft 41 via a keyway. The drive shaft 41 is connected to the U-shaped plate 43 via the bearing seat 45 to support the drive shaft 41 and ensure rotational accuracy, and is then connected to the walking frame 2. The bearing seat 45 is fixed to the U-shaped plate 43, and the U-shaped plate 43 is rigidly connected to the bolting mechanism to form a vibration transmission chain. When the third servo motor 42 is driven, the drive shaft 41 rotates, causing the U-shaped plate 43 and the entire vibration device 4 to move together, causing the bolting working part to generate periodic eccentric vibration. This vibration is transmitted to the bolting mechanism via the U-shaped plate 43, causing the garlic bolt to sway slightly during the bolting and bolting process to reduce bolting resistance while maintaining stable clamping. The vibration device 4 is fixedly installed on the upper part of the walking frame 2 by the vertical bearing seat 45, and the amplitude can be adjusted by replacing the eccentric bushing 44 with different eccentricity. The vibration frequency is controlled by the third servo motor 42, so as to realize the flexible adjustment of amplitude and frequency.

[0025] The garlic scape pulling device is located in the middle of the walking frame 2, below the vibration device 4, and is installed at an inclined angle on the horizontal plane. It is connected to the vibration device 4 and vibrates synchronously with the vibration device 4. It includes multiple garlic scape pulling components arranged along the width of the frame. Each garlic scape pulling component includes two sets of belt conveyor mechanisms arranged side by side. Each set of belt conveyor mechanisms includes a connecting plate 12. The connecting plate 12 is equipped with a front synchronous pulley 11 and a rear synchronous pulley 11. The front synchronous pulley 11 and the rear synchronous pulley 11 are connected by a synchronous belt 14. The synchronous belts 14 on opposite sides of the two sets of belt conveyor mechanisms are in contact with each other to clamp the garlic scapes. The connecting plate 12 is also equipped with a floating clamping device 13 located inside the synchronous belt 14. The floating clamping device 13 includes a baffle, a spring on the baffle, a clamping frame on the end of the spring, and a clamping wheel rotatably mounted on the clamping frame. The two clamping wheels respectively abut against the inner sides of the synchronous belts 14 on opposite sides of the two sets of belt conveyor mechanisms, so that the synchronous belts 14 keep clamping the garlic scapes during the garlic scape pulling process to prevent them from falling off.

[0026] In actual operation, the drive shaft 41 is connected to the control system 3 via the universal joint coupling 54. When the control system 3 drives the system, the synchronous pulleys 11 on both sides drive the synchronous belt 14 to rotate relative to each other, thereby clamping the top of the fed garlic scape. With the help of the rotation of the synchronous belt 14 and the forward movement of the walking frame 2, the top of the garlic scape is pulled backward to remove the scape. After the scape removal is completed, the synchronous belt 14 continues to transport the garlic scape and feed it into the collection box 6. The entire floating clamping device 13 is installed on the walking frame 2 and the connection between the connecting plate 12 and the frame realizes the adjustment of the scape removal height and the gap of the synchronous belt 14 to meet the needs of garlic plants of different growth heights. At the same time, under this adjustment, the garlic scape and garlic leaves are separated during the scape removal process, reducing the damage rate and the rate of missing scapes.

[0027] In this invention, the bolting device 5, vibration device 4, and bolting device 1 are arranged sequentially from front to back on the walking frame 2, forming a clear sequential coordination relationship between the devices. The vibration device 4 is located between the bolting device 5 and the bolting device 1. The fixing method of the U-shaped plate 43 and the bearing seat 45 ensures vibration stability, enabling the whole machine to maintain stable operation in the field, reducing mechanical wear caused by uneven vibration transmission, and extending the service life of the whole machine.

[0028] It should be noted that the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
