Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a self-propelled small-sized leek harvester. Background Art

[0002] Chinese chives, a perennial herbaceous plant of the Liliaceae family, are cultivated in large quantities for their cold-resistance, heat-resistance, and insect-resistance. Under normal circumstances, leeks are harvested 8 to 10 times a year, which requires a lot of harvesting work.

[0003] Some large and medium-sized farms often use large leek combine harvesters to automatically harvest leeks. However, for many leek farmers, large leek combine harvesters are expensive to use and purchase, so they usually have to harvest manually, which results in low overall harvesting efficiency.

[0004] Currently, there are some small harvesters available for small farmers. However, these harvesting machines have poor efficiency and effectiveness, and farmers still need to manually re-harvest the crops after harvesting. The overall harvesting efficiency and labor costs are not up to expectations. Summary of the Invention

[0022] Figure 1 This is a structural diagram of a self-propelled small leek harvester provided in an embodiment of the present application. Figure 1 As shown, the self-propelled small leek harvester includes: a harvester body 10, a straw separating mechanism 20, a clamping roller 30, an electric cutter and a conveying roller 40.

[0023] The harvester body 10 is provided with a walking system, through which the harvester body 10 can have a certain mobility and can automatically move along a set path or an expected path.

[0024] Specifically, such as Figure 3 As shown, the harvester body 10 includes: a body base 11 , a vertical bracket 12 extending from the body base 11 in a height direction, and a gripping armrest 13 .

[0025] The walking system is arranged on the main body base 11. The gripping armrest 13 is fixed on the vertical bracket 12. At least a portion of the gripping armrest 13 extends in the horizontal direction for the user to grip and control the self-propelled small leek harvester.

[0026] The straw separating mechanism 20 comprises a pair of triangular pyramidal straw separating structures 21. These pyramidal straw separating structures 21 extend outward from the front end of the harvester body 10, protruding from the harvester body 10. These structures 21 align the rows of leeks to be harvested, preventing leeks from adjacent rows from being mistakenly harvested.

[0027] Two clamping rollers 30 are provided at the front end of the harvester body to form a clamping area for the leeks. They can rotate around an axis set along a predetermined direction. The axis is a direction that is roughly equivalent to the height direction or at a certain angle to the height direction.

[0028] The electric cutter is fixed to the harvester body 10 and can cut the leeks as they pass by. It can be understood that the height of the electric cutter is the cutting height of the leeks. By providing an appropriate height adjustment mechanism to adjust the height of the electric cutter, the cutting height of the leeks can be adjusted.

[0029] Specifically, such as Figure 3 As shown, a pair of roller mounting brackets 14 are provided at the front end of the main body base 11 for mounting the clamping roller 30 .

[0030] The axis direction of the roller mounting bracket 14 forms a preset acute angle with the height direction. The two roller mounting brackets 14 are arranged roughly opposite each other, so that the pair of clamping rollers 30 rotate around the axis direction under the drive of the sponge conveyor belt and form a clamping area for clamping the leeks.

[0031] In some embodiments, as Figure 2 and Figure 3 As shown, the body base 11 is further provided with a cutter mounting bracket 15 .

[0032] The cutter mounting bracket 15 is located adjacent to the bottom end of the drum mounting bracket 14. The bottom end of the drum mounting bracket is the end close to the ground. The electric cutter can be mounted on the cutter mounting bracket 15 to cut the leeks clamped by the clamping mechanism.

[0033] Specifically, such as Figure 4 As shown, two conveyor rollers 40 are also provided. These are rotating structures located at the rear end of the harvester body and can also rotate about their own axes. Unlike the clamping rollers 30, the axes of the conveyor rollers 40 are arranged horizontally, allowing them to transport the harvested leeks horizontally to a collection device or other similar collection area.

[0034] A sponge conveyor belt is sleeved between the clamping roller 30 and the conveying roller 40. The sponge conveyor belt is a belt-like structure made of a soft elastic material with a certain thickness. On the one hand, the sponge conveyor belt can drive the clamping roller 30 and the conveying roller 40 to rotate synchronously.

[0035] On the other hand, the sponge conveyor belts sleeved by the two clamping rollers are in contact with each other, thereby forming a clamping mechanism for clamping the leeks.

[0036] During the actual leek harvesting process, leeks are clamped and secured within the clamping zone between the sponge conveyor belts of the two clamping rollers. An electric cutter is positioned adjacent to or within the clamping zone, synchronously cutting the leeks as they pass through the clamping mechanism. Finally, the cut leeks, held and transported by the sponge conveyor belts, are moved to the conveyor rollers, where they are simultaneously adjusted to a horizontal orientation.

[0037] In some embodiments, please refer to Figure 2 The walking system includes: guide wheels 41, driving wheels 42 and driving equipment.

[0038] The guide wheel 41 is located at the front end of the main body base 11, for example, at a position corresponding to the cutter mounting bracket 15. The drive wheel 42 is spaced a predetermined distance from the guide wheel 41 and is located at the main body base. The drive device can be any suitable type of power device, such as a travel motor. This drive device is connected to the drive wheel 42 to provide power to the drive wheel, thereby driving the self-propelled small leek harvester.

[0039] In addition, the driving wheel 42 has a wheel diameter larger than the guide wheel 41. For example, the driving wheel 42 is a 40-inch wheel and the guide wheel 41 is a 14-inch wheel. In some cases, the driving wheel 42 can be provided with two and the guide wheel 41 can be provided with one.

[0040] In some embodiments, please refer to Figure 2The self-propelled small leek harvester also includes: an automatic bundling and collecting mechanism 50.

[0041] The automatic bundling and collection mechanism 50 is located on the side of the vertical support 12 that is away from the guide wheel, while the conveyor roller is located on the side of the vertical support 12 that is closer to the guide wheel. As a result, the leeks that leave the sponge conveyor belt of the conveyor roller are fed into the automatic bundling and collection mechanism 50, where they are bundled and packaged.

[0042] Specifically, such as Figure 3 As shown, the automatic bundling and collecting mechanism 50 may be composed of a bundling device 51 and an unloading device 52 .

[0043] The bundling device 51 is an automatic bundling component for bundling the collected leeks. When the number of leeks entering the collection area is sufficient, the user can automatically bundle the leeks by pressing down the bundling device 51.

[0044] The unloading device 52 is a component for unloading bundles of leeks. It has at least one openable and closable shielding component. By controlling the opening of the shielding component, the bundles of leeks contained in the collection area can be unloaded and subsequently processed.

[0045] Figure 5 This is a circuit diagram of a self-propelled small leek harvester provided in an embodiment of the present application. Figure 5 As shown, the self-propelled small leek harvester drives the electric cutter, conveyor roller, and travel motor respectively through the first driver 100, the second driver 200, and the third driver 300. An MCU controller 400 is used internally to control the first driver 100, the second driver 200, and the third driver 300 through PWM pulse wave control.

[0046] In summary, the self-propelled small leek harvester provided in this embodiment utilizes a sponge-like conveyor belt to flexibly clamp the leeks to be harvested, allowing them to be simultaneously cut at the root using an electric cutter. Furthermore, the cut leeks can be flexibly conveyed by the sponge-like conveyor belt, gradually shifting from a vertical orientation to a horizontal orientation until they are delivered to a collection and storage area. Once the leeks have accumulated to a suitable bundle size in the collection and storage area, the user can trigger the baling device to automatically tighten the leeks with the baling band, completing the bundle.

[0047] The above content is a further detailed description of the present invention in conjunction with specific / preferred embodiments, and the specific implementation of the present invention cannot be limited to these descriptions. Those skilled in the art will appreciate that various modifications and improvements can be made without departing from the concept of the present invention, and all of these modifications and improvements fall within the scope of protection of the present invention.
