In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 3 As shown, the present embodiment provides a small tobacco leaf harvesting vehicle that is manually transported and mechanically transported, comprising: a vehicle frame 1, two drive motors 2, two walking mechanisms 3, two tobacco frames 4, two seats 5 and a controller 6.

[0033] The frame 1 includes two support frames 11 arranged opposite to each other on the left and right sides and a connecting frame 12 connecting the upper ends of the two support frames 11. Two walking mechanisms 3 are arranged in parallel and are installed at the bottom of the two support frames 11 in a one-to-one correspondence. Two driving motors 2 drive and connect the two walking mechanisms 3 in a one-to-one correspondence and are respectively arranged on the two support frames 11. At the same time, two tobacco frames 4 are respectively installed on the two support frames 11 for holding the harvested tobacco leaves; two seats 5 are respectively arranged on the two support frames 11, and their heights are adjustable to meet the needs of different harvesters.

[0034] like Figure 1As shown, in order to adapt the spacing between the two walking mechanisms 3 to the distance between different tobacco planting ridges, the spacing between the two walking mechanisms 3 is adjustable, which is convenient for application to planting plots of various sizes and specifications, improves the efficiency of tobacco leaf harvesting, and has a wider scope of application. The harvesters on the two seats 5 can harvest tobacco leaves on both sides without damaging the tobacco plants. At the same time, the spacing between the two support frames 11 is based on the width of the transverse cross-section of the tobacco leaf growth, and the ground clearance of the connecting frame 12 is determined based on the average height of the tobacco plants. At the same time, in order for the harvesting vehicle to be better and more widely used in various terrains, the walking mechanism 3 adopts a crawler structure to improve overall safety and stability.

[0035] like Figures 1 to 3 As shown, a reducer 31 connected by a controller 6 is provided on the walking mechanism 3. At the same time, the controller 6 is installed on the connecting frame 12 to control the connection of two driving motors 2. An operating handle 7 connected to the controller 6 is provided on one side of at least one seat 5. The controller 6 controls the opening and closing of the driving motor 2 and the reducer 31, thereby controlling the moving direction and speed of the entire harvesting vehicle; at the same time, the operating handle 7 can be controlled and adjusted, and the forward, backward and travel speed of the harvesting vehicle can be indirectly controlled through the controller 6.

[0036] In order to better free the hands of the harvesters and improve the efficiency of tobacco leaf harvesting, an image recognition camera 8 is provided on the connecting frame 12 and connected to the controller 6, and a remote controller 9 can control the connection controller 6. The controller 6 can drive the harvester to drive automatically through the pre-set program and the image information collected by the image recognition camera 8, and the control and adjustment of the remote control 9 or the operating handle 7 can fully, flexibly and efficiently control the movement and stop of the harvester. The controller 6 integrates the software and hardware functional units of motor speed control, image recognition (realizing the automatic driving function of the harvester in the furrow), the driving and remote control driving signal reception and processing of the operating handle 7, and the AC-DC conversion unit (providing DC power supply for the control system). The controller 6 is connected to each functional unit through the line pre-buried in the cavity of the frame 1, and the operation of the whole vehicle is realized through the control system.

[0037] In other embodiments, the whole vehicle can adopt a full electric drive working mode, and gasoline generators are installed on both sides of the front of the vehicle to supply electricity for the whole vehicle and provide electricity for the controller 6. The transmission line connecting the generator and the drive motor 2 and the controller 6 is pre-buried in the cavity of the main frame 1. Using a large generator or a large drive motor 2 will cause the single generator to be too large and the load to be unbalanced, resulting in excessive occupation of the ridge space on one side, causing scratches and damage to tobacco leaves and plants during operation; using two generators and two drive motors 2 allows the front of the vehicle to occupy a balanced space on both sides of the ridge, which will not cause crop scratches and damage, and the weight distribution of the whole vehicle is more even, forming a counterweight effect with the rear workstation seat 5. With the auxiliary support of the support wheel 13, it is more stable and reliable to carry two people.

[0038] like Figures 1 to 3 As shown, in order to make the harvesting vehicle more stable and balanced, a support wheel 13 is provided at the bottom of the support frame 11, which is located below the seat 5, and has a good supporting effect on the seat 5 and the harvesting personnel, thereby improving the safety of the operators. At the same time, the drive motor 2 and the seat 5 on the same support frame 11 are respectively located on the opposite sides of the tobacco frame 4 along the walking direction, so that the weight of each part is more evenly and balancedly located in each part of the entire harvesting vehicle, thereby ensuring the stability of the vehicle body.

[0039] When the operation begins, two harvesting workers sit on the left and right seats 5 respectively. The seats 5 are located in the center of the ridges, so that the workers are equidistant from the tobacco plants on both sides, making it convenient to break off the mature tobacco leaves on both sides. The seat 5 can adjust the height of the seat 5, so that the workers can adjust the seat 5 according to the height of the mature tobacco leaves, making harvesting more convenient and comfortable.

[0040] At the same time, for the convenience of tobacco leaf harvesting and loading and unloading, the tobacco frame 4 is detachably mounted on the support frame 11 through a fixing card 43, and the tobacco frame 4 includes a frame body 41 with an upward opening and a movable door 42 installed on one side of the frame body 41 that can be switched, and the lower end of the movable door 42 is hinged on the side of the frame body 41 away from the other tobacco frame 4, and the movable door 42 and the frame body 41 are provided with a latch 44 to prevent the movable door 42 from rotating. The harvesters harvest the left and right mature leaves and put the harvested leaves into the front tobacco frame 4. When the tobacco frame 4 is full and the harvesting vehicle arrives at the end of the field, the latch 44 of the outer movable door 42 of the tobacco frame 4 is unplugged, and the outer movable door 42 is opened to unload the tobacco leaves. The tobacco frame 4 can be detached and replaced by removing the fixing card 43, and the movable door 42 is rotated by operating the latch 44, and the tobacco leaves placed in the frame body 41 can be efficiently and conveniently unloaded, which is efficient and convenient.

[0041] In order to improve the efficiency of harvesting operation, when the harvesting vehicle enters the tobacco ridge, the image recognition automatic driving function for the ridge is activated, so that the harvesting vehicle can automatically drive along the ridge ditch, and the harvesting personnel do not need to drive at the same time. In order to ensure the safety of personnel, the harvesting vehicle is driven by remote control 9 before going to the field for harvesting operation, and the remote control driver walks and follows; during the field harvesting operation, two operators sit on the workstation seats 5 respectively. When the harvesting operator continuously breaks tobacco leaves with both hands (in this case, he cannot free his hands to drive), the image recognition automatic driving function is activated, and the camera collects the ridge ditch image in real time. According to the curvature of the ridge ditch, the driving direction of the harvesting vehicle is corrected, so that the harvesting vehicle always keeps driving along the tobacco ridge, and the walking mechanism 3 is always in the center of the ridge ditch on both sides; at the end of the ridge, the harvesting vehicle is stopped, and the operator gets off the workstation seat 5, stands near the harvesting vehicle, holds the driving remote control 9, and remotely drives the operation vehicle to turn around and enter the adjacent operation ridge, and then sits on the workstation seat 5 to enter the next ridge for harvesting operation. In addition to the ridge and ditch automatic driving function, it is equipped with a driving handle. The operator can intervene and take over the automatic driving function through the driving handle, allowing the harvesting vehicle to switch from automatic driving to manual driving, and realize manual control of the harvesting vehicle's emergency stop, start, left and right steering, acceleration and deceleration and other functions, making the operation process safer and more reliable.

[0042] During actual harvesting, the harvesting workers are brought into the tobacco field, and the mature tobacco leaves are manually identified and broken off by hand, and the broken tobacco leaves are placed in the front tobacco frame 4, so that the continuous harvesting operation of human-machine collaboration is realized. When the tobacco frame 4 is full of tobacco leaves, the tobacco can be unloaded at the head of the field. Compared with traditional manual harvesting, this human-machine operation method can greatly reduce the labor intensity of the harvesting process and improve the efficiency of manual harvesting operations.

[0043] The harvesting vehicle has a simple structure, flexible control, good passability, and is suitable for harvesting irregular small plots in hilly and mountainous areas. It has good human-machine coordination and greatly reduces the labor intensity of operators.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
