Description

Technical Field

[0001] This invention relates to the field of agricultural harvesting machinery, specifically, to the design of a multi-row garlic harvester. Background Technology

[0002] Garlic is generally grown on a large scale; however, my country's mechanized harvesting technology for garlic is relatively lagging behind, which seriously restricts the development of the garlic industry.

[0003] Garlic is a labor-intensive crop, and harvesting is a crucial part of its production process. Traditional manual harvesting involves removing the stems, leaves, and roots of the plant to obtain the fruit, which is extremely labor-intensive, time-consuming, inefficient, wastes a lot of manpower, and increases harvesting costs.

[0004] Existing garlic harvesters have a limited number of rows that can be harvested simultaneously, making it impossible to harvest large quantities of garlic at the same time. Furthermore, existing garlic harvesters can only cut off the stems and leaves of garlic, but cannot cut off the roots. In addition, garlic roots carry a large amount of soil with them during harvesting, and the soil clods can easily damage the garlic skin by colliding with each other during the harvesting process, affecting the quality of the garlic. Summary of the Invention

[0016] By incorporating a front-mounted guide component, along with central and edge guide forks, the garlic stems and leaves can be effectively guided, ensuring accurate entry into the clamp conveyor assembly. A conveyor tension adjustment component allows for adjustment of the conveyor chain tension. A multi-row power transmission assembly enables axial power transmission between adjacent main drive shafts via a transmission spline shaft, achieving power transmission for multi-row harvesting without being limited by the number of harvesting groups. This facilitates disassembly, replacement, and maintenance of the multi-row power transmission assembly. A root cutting component allows for rapid removal of garlic roots. A chain adjustment component allows for adjustable chain tension, increasing the adaptability of the garlic stems and leaves during transport. A power transmission universal joint ensures downward power transmission even after angle changes. A belt conveyor assembly, using a conveyor belt, prevents damage to the stems and leaves near the garlic. The system conveys garlic and features a garlic stem and leaf cutter powered by a root cutting component to cut the garlic stems and leaves, thus facilitating harvesting. A stem and leaf crushing component, through the interaction of the crushing cutter and the cutter limit baffle, crushes and cuts the garlic stems and leaves, preventing them from tangling and accumulating during transport, thus reducing the impact of tangling and accumulation on the harvester's efficiency. A soil-shaking screen component preliminarily removes loose soil carried during harvesting. An eccentric shaking wheel drives the soil-shoveling plate to reciprocate and also shakes the soil-removing screen, causing soil accumulated on the screen to fall off and preventing it from affecting harvesting efficiency. A ratchet soil-removing component, through the rotation of the soil-removing sleeve, continuously beats the garlic roots, removing clods of soil adhering to the roots, thus breaking up and removing the soil.

[0031] Example: Figure 1 As shown, a multi-row garlic harvester includes a harvester frame 1. The harvester frame 1 is connected to a clamping rod conveyor component 3. The clamping rod conveyor component 3 includes two conveying side plates 31. The two conveying side plates 31 are connected to a front guide component 2. Multiple sets of conveying assemblies 34 are connected between the two conveying side plates 31. The multiple sets of conveying assemblies 34 are driven to a root cutting component 4. The root cutting component 4 is driven to a belt conveyor component 5. The conveying side plates 31 are connected to a soil shaking screen component 7. The conveying side plates 31 are connected to a ratchet soil removal component 8. A stem and leaf crushing component 6 is connected inside the harvester frame 1.

[0032] like Figures 1 to 4 As shown, a fixed beam 32 is fixedly connected between the two conveyor side plates 31. Guide baffles 33 are connected to multiple sets of conveyor components 34. Each set of conveyor components 34 includes two conveyor plates 341. A conveyor drive shaft 342 and a conveyor driven shaft 344 are rotatably connected to each of the two conveyor plates 341. A conveyor drive gear 343 is fixedly connected to the conveyor drive shaft 342, and a conveyor driven gear 345 is fixedly connected to the conveyor driven shaft 344. A conveyor drive chain 346 is connected between the conveyor drive gear 343 and the conveyor driven gear 345. The conveyor drive gear 343 and the conveyor driven gear 345 drive the conveyor drive chain 346 to rotate, thus transporting the garlic. Compared to traditional belt conveyors, the conveyor drive chain 346 offers better stability, preventing the harvesting progress from being interrupted due to slippage or other factors during transport.

[0033] The conveying drive shaft 342 is connected to multiple rows of power transmission components 36. The multiple rows of power transmission components 36 include a main drive sleeve 361, a secondary drive sleeve 362 fixedly connected to the side of the main drive sleeve 361, multiple main drive shafts 363 sleeved inside the main drive sleeve 361, a main drive bevel gear 365 fixedly connected to the main drive shaft 363, a transmission spline shaft 364 for axial transmission fixedly connected to one end of the main drive shaft 363, a secondary drive shaft 366 sleeved inside the secondary drive sleeve 362, a secondary drive bevel gear 367 fixedly connected to the driven shaft, the secondary drive bevel gear 367 meshing with the main drive bevel gear 365, and the secondary drive shaft 366 fixedly connected to the conveying driven shaft 344. The main drive shaft 363 transmits axial power through the drive spline shaft 364, thereby enabling multiple main drive shafts 363 to rotate simultaneously. The multiple main drive shafts 363 facilitate future replacement and maintenance. The power is transmitted in reverse direction through the secondary drive bevel gear 367 and the main drive bevel gear 365.

[0034] The conveyor plate 341 is connected to a conveyor tension adjustment assembly 35. The conveyor tension adjustment assembly 35 includes a tension fixing rod 351, which is fixedly connected to the upper surface of the conveyor plate 341. A tension telescopic rod 352 is slidably connected inside the tension fixing rod 351. One end of the tension telescopic rod 352 is fixedly connected to a tension telescopic shaft 353, which is rotatably connected to the conveyor driven shaft 344. The tension telescopic rod 352 can drive the tension telescopic shaft 353 to move back and forth, thereby adjusting the position of the conveyor driven gear 345 and changing the tension of the conveyor transmission chain 346. Excessive tension will cause wear to the stems and leaves of the garlic, leading to breakage of the stems and leaves during the backward transport of the garlic. Insufficient tension will prevent the garlic from being transported backward.

[0035] like Figure 5As shown, the front guide component 2 includes two guide connecting side plates 21, both of which are fixedly connected to the conveying side plate 31.

The angle of the central guide fork 235 can be adjusted by the positioning mounting bracket 231 and the telescopic mounting bracket 232. The overall position of the central guide component 23 can be adjusted by the guide fixing rod 22. The follow-up spring 234 can ensure that the central guide fork 235 can move with the undulation of the ground when it moves in the field, preventing the central guide fork 235 from colliding with the ground.

[0036] The edge guiding assembly 24 includes an edge mounting bracket 241, which is fixedly connected to the side of the guide connecting side plate 21. A telescopic cylinder 242 is connected to the side of the edge mounting bracket 241. One end of a cylinder support rod 243 is fixedly connected to the output end of the telescopic cylinder 242. The other end of the cylinder support rod 243 is fixedly connected to a follower wheel frame 244. A follower roller 245 is rotatably connected to the follower wheel frame 244. An edge support rod 246 is slidably connected to the positioning mounting bracket 231. One end of an edge guiding fork 248 is rotatably connected to the follower wheel frame 244. An edge spring 247 is connected between the other end of the edge guiding fork 248 and the edge support rod 246. The follower roller 245 can better guide the harvester forward. The cylinder support rod 243 and telescopic cylinder 242 realize the up and down movement of the follower roller 245, so that the follower roller 245 can move with the undulation of the ground. The rotating edge guide fork 248 installed on the follower roller 245 can also realize the undulation of the ground.

A chain adjustment assembly 45 is connected to the cutting mounting plate 41. The chain adjustment assembly 45 includes an adjustment mounting baffle 451, which is fixedly connected to the cutting mounting plate 41. A chain adjustment rod 452 is connected to the adjustment mounting baffle 451. One end of the chain adjustment rod 452 is rotatably connected to the chain driven gear 432. A chain adjustment spring 453 is sleeved on the chain adjustment rod 452. The power transmission universal joint 42 transmits power to the chain drive assembly 43. The chain drive gear 431 transmits power to the driven gear 432 via the drive chain 433. The drive chain 433 also transmits power to the cutting drive gear 443, thereby driving the root cutter 444 to rotate rapidly and achieve the purpose of cutting roots. The tension of the drive chain 433 can be adjusted by the chain adjustment assembly 45 to ensure the support force for the garlic stems and leaves.

[0038] like Figure 9 and 10As shown, the belt conveyor component 5 includes a belt conveyor plate 51, on which a belt drive assembly 52 is connected.

The multiple crushing cutters 633 further enhance the crushing efficiency of garlic stems and leaves. The cutter limiting baffle 621 and the baffle fixing plate 622 can also effectively prevent garlic stems and leaves from getting tangled on the crushing cutter 633 and being unable to be crushed.

[0040] like Figure 11As shown, the soil-shaking screen component 7 includes a component connecting side plate 71, which is fixedly connected to the conveying side plate 31.

The soil-removing bar 835 effectively breaks up soil clumps at the garlic roots, achieving soil removal. The first transmission gear 823 and the second transmission gear 824 provide speed regulation, thereby increasing the rotational speed of the soil-removing ratchet assembly 83 and improving its soil-removing effect. The one-way limiting ratchet 832 and the ratchet limiting block 833 enable one-way rotation of the soil-removing sleeve 834, preventing the garlic conveyor from driving the soil-removing sleeve 834 to rotate and reducing the soil removal effect on the garlic roots.
