Description

Technical Field

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

[0002] For root crops like garlic, harvesting still relies heavily on manual labor to dig the garlic out of the soil and then manually trim the seedlings. This method is very inefficient and easily breaks or scratches the garlic's surface, significantly impacting its long-term preservation. Currently, there are some semi-mechanized harvesters, typically using hand-held tractors or small four-wheeled tractors with attached harvesting devices. After digging the garlic, it is laid out on the ground for manual collection. However, this method is inefficient and cannot meet practical needs. Utility Model Content

[0003] In order to address the shortcomings of existing technologies, this utility model discloses a garlic and onion combined harvester, which solves the technical problems of low harvesting efficiency and damage to garlic during harvesting in existing technologies for root vegetables such as garlic.

[0004] This utility model is achieved through the following technical solution: A garlic and onion combine harvester includes a frame with a tracked walking mechanism at the bottom. A cutting platform is provided at the front end of the frame. The cutting platform includes a garlic sprout cutting mechanism, a garlic sprout crushing mechanism, a garlic digging mechanism, and a lifting and conveying mechanism. On the frame behind the cutting platform, a garlic-soil separation mechanism, a lifting mechanism, a film removal mechanism, a drum slag discharge mechanism, and a collection mechanism are arranged in sequence. The garlic-soil separation mechanism and the lifting mechanism have partially overlapping projections on the horizontal plane. The lifting mechanism and the film removal mechanism have partially overlapping projections on the horizontal plane. The drum slag discharge mechanism is inclined from the front end to the rear end from top to bottom, and the front end of the drum slag discharge mechanism is located below the film removal mechanism.

[0005] Further optimized, the soil-garlic separation mechanism includes a lower conveyor chain mechanism, a soil-crushing roller located above the front end of the lower conveyor chain mechanism, and an upper conveyor chain mechanism located on a frame above the lower conveyor chain mechanism and behind the soil-crushing roller. The upper conveyor chain mechanism includes an upper conveyor chain, which is connected to each other by several crossbars. Several rubber rods are located on the crossbars. The drive shaft of the lower conveyor chain mechanism is poweredly connected to a first hydraulic motor located on the frame. The soil-crushing roller and the drive shaft of the upper conveyor chain mechanism are poweredly connected to a gearbox via a chain drive mechanism. The gearbox is poweredly connected to the first hydraulic motor. The rotational speed of the lower conveyor chain mechanism is higher than that of the upper conveyor chain mechanism.

[0006] In a further optimized configuration, the lifting mechanism includes a lifting belt with several lifting plates on it, and the shaft of the lifting mechanism is connected to a second hydraulic motor mounted on the vehicle frame.

[0007] In a further optimized manner, the film removal mechanism includes a conveyor belt with a plurality of protrusions spaced along its length and teeth on the protrusions. The shaft of the lifting mechanism is connected to a second hydraulic motor mounted on the frame.

[0008] Further optimized, a film collection screen is provided on the frame below the rear end of the film removal mechanism.

[0009] In a further optimized manner, the drum slag discharge mechanism includes several drums arranged in parallel, and the power source of the drums is a second hydraulic motor mounted on the chassis.

[0010] In a further optimized manner, the collection mechanism includes a flip-up flap, with several bagging hoppers on the frame behind the flap, and a conveyor belt on the frame below the flap. When the flap is placed horizontally, garlic cloves rolling off the drum slag discharge mechanism fall into the bagging hoppers through the flap. When the flap is tilted and lowered, garlic cloves rolling off the drum slag discharge mechanism fall into the conveyor belt. The shaft of the conveyor belt is connected to a gear steering box mounted on the frame, and the power of the input shaft of the gear steering box comes from a second hydraulic motor mounted on the frame.

[0011] The beneficial effects of this utility model are as follows: This invention enables automatic harvesting of root crops such as garlic while avoiding damage to the garlic, allowing for long-term preservation and significantly improving harvesting efficiency. Attached Figure Description

Detailed Implementation

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] As shown in Figures 1-4, a garlic and onion combine harvester includes a frame 1 with a tracked walking mechanism at the bottom. A cutting platform 2 is provided at the front end of the frame 1. The cutting platform 2 includes a garlic sprout cutting mechanism, a garlic sprout crushing mechanism, a garlic digging mechanism, and a lifting and conveying mechanism. On the frame 1 behind the cutting platform 2, a garlic-soil separation mechanism, a lifting mechanism, a film removal mechanism, a drum slag discharge mechanism, and a collection mechanism are arranged in sequence. The projections of the garlic-soil separation mechanism and the lifting mechanism on the horizontal plane partially overlap. The projections of the lifting mechanism and the film removal mechanism on the horizontal plane partially overlap. The drum slag discharge mechanism is inclined from the front end to the rear end from top to bottom. The front end of the drum slag discharge mechanism is located below the film removal mechanism.

[0016] The harvester of this utility model first uses a header to cut and crush garlic sprouts and dig up garlic. The dug garlic is then transported to a soil-garlic separation mechanism via a lifting and conveying mechanism of the header. The specific structure of the header is described in the applicant's previously filed patent application, application number "2025208651131," and will not be repeated here. Of course, existing structural designs capable of achieving the above-mentioned header functions can also be used. After the soil is removed, the garlic bulbs fall into the lifting mechanism, which then lifts them into the film removal mechanism to remove the film (which is used when planting garlic). The film-removed garlic bulbs then fall into a drum-type slag removal mechanism for further slag removal, finally reaching the collection mechanism. This harvester of the utility model can automatically harvest root crops such as garlic while avoiding damage to the garlic, enabling long-term storage of garlic, and improving harvesting efficiency and quality.

[0017] In some embodiments, the garlic-soil separation mechanism includes a lower conveyor chain mechanism 3, a soil-crushing roller 4 positioned above the front end of the lower conveyor chain mechanism, and an upper conveyor chain mechanism positioned on a frame 1 above the lower conveyor chain mechanism 3 and behind the soil-crushing roller 4. The upper conveyor chain mechanism includes an upper conveyor chain 5, which is connected to each other by several crossbars 6. Several rubber rods 7 are mounted on the crossbars 6. The drive shaft of the lower conveyor chain mechanism is powered by a first hydraulic motor 8 mounted on the frame 1. The soil-crushing roller 4 and the drive shaft of the upper conveyor chain mechanism are powered by a chain drive mechanism and a gearbox 9. The gearbox 9 is powered by the first hydraulic motor 8. The lower conveyor chain mechanism 3 includes an upper conveyor chain (not shown), which is connected to each other by steel bars (not shown). Rubber sleeves are fitted onto the steel bars. The lower conveyor chain is composed of flexible components to avoid damaging the garlic.

[0018] The garlic excavated from the cutting platform first reaches the lower conveyor chain mechanism. The soil crushing roller 4 can crush larger soil clods, and the soil will fall through the hollow gaps of the lower conveyor chain mechanism. The rotation speed of the lower conveyor chain mechanism is higher than that of the upper conveyor chain mechanism. The rubber rod 7 continuously agitates the garlic, which helps the soil to separate and fall. At the same time, the rubber rod 7 is a flexible component to prevent damage to the garlic.

[0019] In some embodiments, the lifting mechanism includes a lifting belt 10, a plurality of lifting plates 11 are provided on the lifting belt 10, and the rotating shaft of the lifting mechanism is connected to a second hydraulic motor 12 provided on the frame 1.

[0020] In some embodiments, the film removal mechanism includes a conveyor belt 13, on which a plurality of protrusions (not shown) are provided at intervals along the length of the conveyor belt 13, and teeth (not shown) are provided on the protrusions. The rotating shaft of the lifting mechanism is connected to a second hydraulic motor 12 mounted on the frame 1.

[0021] The garlic cloves fall from the top of the lifting mechanism onto the conveyor belt 13, where the teeth can hook the film and complete the film removal process.

[0022] In some embodiments, a film collecting screen 14 is provided on the frame 1 below the rear end of the film removal mechanism for collecting film.

[0023] In some embodiments, the drum slag removal mechanism includes several drums 15 arranged in parallel, and the power of the drums 15 is derived from a second hydraulic motor 12 mounted on the frame 1. Garlic bulbs are further descrambled by the inclined drum slag removal mechanism, with soil and other debris falling through the perforated gaps in the drums, resulting in garlic bulbs with very little debris. When the harvester of this application is used to harvest onions, the drum slag removal mechanism can be replaced with a corn peeling mechanism. The corn peeling mechanism is an existing mechanism, generally including a rotating roller with fish-scale rollers on both sides to separate the onion seedlings from the onions. This utility model can replace the intermediate mechanism with different ones depending on the actual crop being harvested.

[0024] In some embodiments, the collection mechanism includes a flip-up flap 16, a plurality of bag hoppers 17 are provided on the frame 1 behind the flap 16, and a conveyor belt 18 is provided on the frame 1 below the flap 16. When the flap 16 is placed horizontally, garlic cloves rolling off the drum slag discharge mechanism fall into the bag hoppers 17 through the flap 16. When the flap 16 is tilted and lowered, garlic cloves rolling off the drum slag discharge mechanism fall into the conveyor belt 18. The shaft of the conveyor belt 18 is connected to a gear steering box 19 provided on the frame 1. The power of the input shaft of the gear steering box 19 comes from a second hydraulic motor 12 provided on the frame 1.

[0025] Depending on the chosen collection method, if bagging is desired, the flap 16 is laid flat, allowing the garlic cloves rolling off the drum discharge mechanism to fall through the flap 16 into the bagging hopper 17, which holds woven bags. Once full, the bags are replaced. If collection is desired into a truck bed, the flap 16 is lowered, allowing the garlic cloves rolling off the drum discharge mechanism to fall onto the conveyor belt 18, and then transported to the truck bed of another vehicle via a lifting mechanism. The lifting mechanism can be selected and installed as needed. The conveying direction of the conveyor belt can be changed via the operating lever of the gear steering box 19. The transmission mechanism between the gear steering box 19 and the conveyor belt 18 is not shown in the figure.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model. For those skilled in the art, any alternative improvements or transformations made to the implementation of this utility model fall within the protection scope of this utility model.

[0027] Any aspects of this utility model not described in detail are known to those skilled in the art.
