[0003] (1) Existing crop harvesting robots: Most of the products on the market are large-scale crop harvesting machines, which are expensive. For small farms, the cost of purchasing and maintaining these machines may exceed the cost of crop investment.

[0004] (2) Modern large-scale harvesting equipment is usually equipped with complex automated systems and multiple functions. Although the complex system improves applicability, it also increases the skill requirements of the operator and reduces the reliability of the equipment for a single crop. Improper operation by the operator may lead to equipment failure and poor harvesting results.

[0005] (3) Large harvesting equipment usually uses diesel fuel. As a flammable and explosive liquid, diesel fuel has a relatively low flash point and is easy to mix with air to form flammable gas. In dry and high-temperature working environments, it needs to operate under high load for a long time, which can easily lead to unsafe accidents. In addition, diesel engines produce incomplete combustion gases and particulate matter during combustion, which have a huge impact on human health and the environment.

Detailed Implementation

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] Please refer to Figures 1 to 4. This embodiment provides a leafy vegetable harvester suitable for operation in mountainous and hilly areas, including a transmission mechanism 1, a reeling device 2, a tracked walking mechanism 3, and a height adjustment mechanism 4; the specific structure is as follows:

[0029] The transmission mechanism 1 includes a transmission frame 1.1, a frame support 1.2, and a transmission roller assembly. The frame support 1.2 is located at the bottom of the transmission frame 1.1. The transmission roller assembly includes multiple transmission rollers 1.3 mounted on the transmission frame 1.1. Each transmission roller 1.3 has a transmission gear 1.4 at one end, and all transmission gears 1.4 are located on the same side of the transmission frame 1.1. All transmission gears 1.4 are connected by a chain (not shown in the figure) for ring chain transmission. A first drive device drives the chain to rotate via an output gear, thereby rotating the transmission rollers 1.3. In this structure, a row of transmission gears 1.4 is arranged on one side of the transmission frame and welded to both sides of the transmission rollers. The first drive device controls the output gear, which drives this row of gears to rotate via chain transmission, thus rotating the transmission rollers. A cutting blade 1.1a is located at the bottom front end of the transmission frame 1.1. This cutting blade is detachable from the transmission frame for easy replacement; alternatively, it can be integrally formed with the transmission frame. The roller-type conveyor can sieve fine sand, clods of soil, weeds, etc.

[0030] The reeling device 2 is located at the front end of the transmission mechanism 1. The reeling device 2 includes a reeling roller shaft, a plurality of reeling fan blades 2.1 arranged in the circumferential direction of the reeling roller shaft, and two reeling support arms 2.2 located at the front of both sides of the transmission frame 1.1. One end of the reeling support arm 2.2 is fixedly connected to the transmission frame 1.1, and the other end of the reeling support arm 2.2 is rotatably connected to the reeling roller shaft.

[0031] There are two tracked walking mechanisms 3, respectively located on both sides of the frame support 1.2. Each tracked walking mechanism includes a track 3.1, a spur gear 3.2, and an idler pulley assembly 3.3. The spur gear 3.2 and the idler pulley assembly 3.3 are located within the track 3.1. The spur gear 3.2 is driven to rotate by a second drive device to move the track 3.1 and the idler pulley assembly 3.3, thereby enabling the leafy vegetable harvester to move forward and backward and turn on the spot. The idler pulley assembly 3.3 includes three idler pulleys spaced horizontally within the track 3.1 and connected by an idler linkage. The spur gear is located above the two rear idler pulleys and is connected to the track 3.1 for transmission. In this structure, each tracked walking mechanism includes a second drive device, which controls the differential rotation of the spur gears of the two tracked walking mechanisms 3, thereby enabling the leafy vegetable harvester to turn and turn. The first drive device and the second drive device are drive motors.

[0032] A height adjustment mechanism 4 is located at the bottom rear of the conveying mechanism 1 and is used to adjust the conveying angle of the conveying mechanism 1. The height adjustment mechanism 4 includes a hinged height adjustment linkage assembly 4.1 and a height adjustment bolt 4.2. The height adjustment bolt 4.2 passes through the height adjustment linkage assembly 4.1, and one end of the bolt has a handle for operation. In this structure, the height adjustment linkage assembly 4.1 is a rhomboid structure hinged between each link. By operating the height adjustment bolt 4.2, the height of the height adjustment linkage assembly 4.1 is adjusted, thereby adjusting the harvesting height of the leafy vegetable harvester, which in turn adjusts the conveying angle of the conveying mechanism 1. The conveying angle of the conveying mechanism 1 is 15°~28° to prevent leafy vegetables from rolling and clogging.

[0033] In one specific embodiment, the frame support 1.2 includes a pair of symmetrically arranged frame plates 1.2a and a frame connector 1.2b disposed between the pair of frame plates 1.2a. The frame connector 1.2b is rotatably connected to the transverse connecting rod 1.1b at the bottom of the transmission frame 1.1. In this structural arrangement, the rotation of the frame support 1.2 and the transverse connecting rod 1.1b allows for adjustment of the conveying angle of the transmission mechanism 1. Simultaneously, in conjunction with the height adjustment mechanism 4, the transmission mechanism 1 remains stable after height adjustment, preventing any back-and-forth swaying or instability.

[0034] In one specific embodiment, a leafy vegetable collection basket 5 is also provided at the rear bottom of the conveyor frame 1.1 to receive the conveyed leafy vegetables; a collection basket support 6 is connected to the frame support 1.2, and the leafy vegetable collection basket 5 is set on the collection basket support 6. A handrail 7 is also provided at the rear end of the collection basket support 6. This structure is simple and reasonable.

[0035] In one specific embodiment, the leafy vegetable harvester also includes a remote control system, which comprises a smart remote controller and a remote controller receiver for receiving remote control signals. The remote controller receiver is connected to the first drive unit and the second drive unit, respectively. This configuration allows the harvester to be started, stopped, and its speed adjusted via the remote controller.

[0036] In this invention, the tracked walking mechanism employs spur gears and tracks, enabling it to turn around on the spot and achieve high obstacle-crossing capability. The tracked walking mechanism design gives the harvester better maneuverability and stability in complex terrain such as hills and mountains. This invention also features a compact design, making it suitable for operation in confined spaces.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
