Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a tracked garlic harvester. Background Technology

[0002] As an important economic crop in my country, the level of mechanization in the harvesting process of garlic directly affects the planting benefits. At present, existing garlic harvesting equipment generally suffers from problems such as low efficiency, high damage rate and poor adaptability when dealing with complex soil conditions.

[0003] In the soil treatment stage, existing harvesting equipment often lacks an effective soil pretreatment mechanism when facing heavy clay soil or compacted plots formed by long-term cultivation. This leads to a significant increase in the resistance of the digging parts to enter the soil. At the same time, the compacted soil that is not sufficiently broken up is easy to stick to the surface of the digging parts, resulting in uneven digging depth. This causes some garlic to be cut off due to digging too deep or left in the field due to digging too shallow, resulting in a high rate of missed harvesting.

[0004] In the root separation and harvesting stage, existing equipment mostly adopts a single digging or rigid clamping method, which does not effectively resolve the binding force between garlic roots and soil. When garlic seedlings are directly pulled out by mechanical force, the friction between the fibrous roots and soil exceeds the tensile strength of the stem, resulting in a stem breakage rate of over 20%. Furthermore, the integrity of the garlic bulb's skin is significantly reduced compared to ideal working conditions due to friction with the soil during dragging. In addition, roots that are not completely separated often carry large clumps of soil, increasing the energy consumption and cost of subsequent soil cleaning processes. The broken roots remaining in the field will also affect the planting quality of the next season's crop. In clay soil environments, traditional garlic harvesters are difficult to adapt to soil conditions, resulting in a low harvesting rate of intact garlic, which is far below the market's demand for high-quality garlic.

[0005] In terms of overall operational efficiency, traditional harvesting equipment suffers from poor process coordination due to the lack of coordinated design among its functional modules. Furthermore, the rigid extraction structure is poorly adaptable to deviations in the growth angle of garlic sprouts, resulting in a high rate of missed pickups. This necessitates manual secondary picking, further increasing harvesting and planting costs. Utility Model Content

[0006] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a tracked garlic harvester that can solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tracked garlic harvester, comprising a base, an engine fixedly connected above the base, a gearbox fixedly connected above the base, the power output of the engine being at the input end of the gearbox, a vibrating arm rotatably connected to one power output end of the gearbox, an eccentric wheel fixedly installed at this end, and a digging shovel fixedly connected to the other end of the vibrating arm.

[0008] A frame is fixedly connected to the rear end of the base, and a motor is fixedly installed at the rear end of the base. A drive sprocket is fixedly connected to the output shaft of the motor. A rotating shaft is rotatably connected to the top of the frame, and a driven gear shaft is rotatably connected to the top of the frame. The drive sprocket is connected and meshed with the sprocket on the rotating shaft through a transmission chain.

[0009] The gear on the rotating shaft meshes with the gear on the driven gear shaft. A small sprocket is fixedly connected to the lower end of the driven gear shaft. The small sprockets mesh with each other through a pull chain, and a clamping block is fixedly installed on the pull chain.

[0010] Preferably, a bracket is fixedly connected to the front end of the base, and a soil-loosening plow is fixedly installed on the bracket.

[0015] Preferably, a guide rod is fixedly installed at the front end of the frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The tracked garlic harvester is placed between two rows of garlic seedlings by the operator, the engine and motor are started, the track starts to move, the soil loosening plow loosens the soil to prevent the digging shovel from blocking the soil, the digging shovel vibrates to cut the roots, the guide rod guides the garlic seedlings after the roots are cut to one place, the pull chain starts to pull the garlic seedlings out of the soil. The soil loosening is done first and then the roots are vibrated to cut. The soil loosening breaks the soil compaction and reduces the resistance of the subsequent root cutting operation. After the roots are cut, the garlic seedlings are pulled out, which improves the continuity and integrity of the operation, reduces the damage to the garlic bulbs, and ensures the quality of the product. It is highly efficient in adapting to complex working conditions, improves the efficiency of operation, and simplifies the subsequent processing.

[0018] (2) When the tracked garlic harvester starts the motor, the drive sprocket drives the shaft to rotate through the transmission chain, and the shaft drives the driven gear shaft to rotate, so the small sprocket starts to rotate. The pulling chain starts to move back and forth along the set trajectory. The clamping block follows the movement of the pulling chain. The clamping block makes the garlic shoots more stable when pulling them. The guide rod can gather the garlic shoots together for easy pulling. Attached Figure Description

[0029] Please see Figure 1-4 This utility model provides a technical solution: a tracked garlic harvester, including a base 1, an engine 4 fixedly connected to the top of the base 1, a gearbox 5 fixedly connected to the top of the base 1, the power output of the engine 4 is at the input end of the gearbox 5, a vibrating arm 6 is rotatably connected to one power output end of the gearbox 5, an eccentric wheel is fixedly installed at this end, a digging shovel 7 is fixedly connected to the other end of the vibrating arm 6, a track 17 is provided below the base 1, another power output of the gearbox 5 is on the track 17, a bracket 3 is fixedly connected to the front end of the base 1, a loosening plow 2 is fixedly installed on the bracket 3, and a handrail 8 is fixedly connected to the base 1;

[0030] Start the engine 4, which drives the gearbox 5 to operate. One output of the gearbox 5 transmits power to the track 17 to move and push the soil-loosening plow 2 to break the soil. The other output of the gearbox 5 is converted into vibration through the vibrating arm 6, which drives the digging shovel 7 to vibrate.

[0031] The principles and structures of the engine 4, gearbox 5, and tracks 17 are similar to those of existing fuel-powered micro-tillers and are well-known to professionals in this field, so their internal structures will not be described in detail.

[0032] A frame 9 is fixedly connected to the rear end of the base 1. A motor 15 is fixedly installed at the rear end of the base 1. A drive sprocket 10 is fixedly connected to the output shaft of the motor 15. A rotating shaft 12 is rotatably connected above the frame 9. A driven gear shaft 11 is rotatably connected above the frame 9. The drive sprocket 10 is connected and meshed with the sprocket on the rotating shaft 12 through a transmission chain 13.

[0033] The gear on the rotating shaft 12 meshes with the gear on the driven gear shaft 11. A small sprocket 20 is fixedly connected to the lower end of the driven gear shaft 11. The small sprockets 20 mesh with each other through the pull chain 18. The pull chain 18 is set in a Y-shaped trajectory according to the distribution of the small sprockets 20. A clamping block 19 is fixedly installed on the pull chain 18. A guide rod 16 is fixedly installed at the front end of the frame 9. A lifting wheel 14 is fixedly connected to the rear end of the frame 9.

[0034] When the motor 15 is started, the drive sprocket 10 drives the rotating shaft 12 to rotate via the transmission chain 13. The rotating shaft 12 drives the driven gear shaft 11 to rotate, thereby causing the small sprocket 20 to start rotating. The pulling chain 18 begins to reciprocate along the set trajectory. The clamping block 19 follows the movement of the pulling chain 18. The clamping block 19 makes the garlic sprouts more stable when pulling them out. The guide rod 16 can gather the garlic sprouts together for easy pulling.

[0035] Working principle: When in use, the operator places the harvester between two rows of garlic seedlings, starts the engine 4 and motor 15, the track 17 starts to move, the loosening plow 2 loosens the soil to prevent the digging shovel 7 from not entering the soil smoothly and causing blockage, the digging shovel 7 vibrates to cut the roots, the guide rod 16 guides the garlic seedlings after the roots are cut to one place, and the pull chain 18 starts to pull the garlic seedlings out of the soil.

[0036] Pre-loosening the soil before vibration to cut the roots breaks up soil compaction, reducing resistance to subsequent root cutting operations. After root cutting, the roots are pulled out, improving the continuity and integrity of the operation, reducing damage to the garlic bulbs, ensuring product quality, efficiently adapting to complex working conditions, improving operational efficiency, and simplifying subsequent processing.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
