[0032] 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.

[0033] like Figures 1 to 3 As shown, the present embodiment provides a fully automatic tobacco leaf harvester for hilly and mountainous areas, comprising: a frame 1, a support 2, a walking device 3, a harvesting device 4, a conveying device 5, a collecting device 6, a seat 7 and an operating device 8.

[0034] Among them, the walking device 3 includes two driving mechanisms 31 and two crawler-type walking mechanisms 32. The two walking mechanisms 32 are arranged in parallel and are respectively installed on both sides of the bottom of the frame 1 of the gantry structure. The width is determined based on the left and right horizontal outline dimensions of the tobacco leaves of the tobacco plant; the two driving mechanisms 31 are installed on both sides of the rear end of the frame 1 along the forward direction, and the two walking mechanisms 32 are connected by a one-to-one drive, and the spacing is equal to the center distance of adjacent ridges; the crawler structure can walk better in hilly and mountainous areas, and can lower the overall center of gravity, lower the center of gravity, and balance the mass, greatly improving the climbing and descending anti-overturning ability of the vehicle, improving the safety and stability of the overall walking operation, and reducing the bumps of driving on undulating ground.

[0035] At the same time, the bracket 2 is installed on the frame 1, and the harvesting device 4 is installed on the bracket 2 so as to be movable and adjustable in the up and down directions, and is used to harvest tobacco leaves passing through the tobacco beads in the frame 1. The conveying device 5 is installed on the frame 1, and is used to collect the tobacco leaves harvested by the harvesting device 4 and lift and transport them upward. The collecting device 6 is installed on both sides of the frame 1, and is used to receive the tobacco leaves lifted and output from the conveying device 5. The seat 7 is installed at the front end of the frame 1 along the forward direction, and the operating device 8 is installed on one side of the seat 7 to control and connect the two driving mechanisms 31. The staff can sit on the seat 7 to control the forward direction of the harvester. Due to the operation in the hilly and mountainous areas, the planting of tobacco beads will be adjusted according to the terrain, and there is no neat and regular distribution in the plain area. The staff sitting in front of the forward direction can better control the direction of travel, and at the same time, can observe the height of the tobacco leaves to be harvested on the tobacco beads to ensure the efficiency of tobacco leaf harvesting.

[0036] like Figure 3 As shown, the conveying device 5 includes two conveying mechanisms 51 and two lifting mechanisms 52. The two conveying mechanisms 51 are arranged side by side on the frame 1 and below the harvesting device 4, and are used to horizontally convey the tobacco leaves falling thereon. The two lifting mechanisms 52 are arranged on the side away from each other of the two conveying mechanisms 51, and are respectively used to lift the tobacco leaves conveyed by the two conveying mechanisms 51. In addition, an introduction plate 53 for guiding tobacco beads into between the two conveying mechanisms 51 is provided at the front end of the two conveying mechanisms 51 along the forward direction.

[0037] Meanwhile, the lifting mechanism 52 includes a lifting assembly 54 and a pressing assembly 55. The pressing assembly 55 includes a plurality of connectors 551 and a plurality of pressing rollers 552. The plurality of pressing rollers 552 are rotatably mounted on the side of the lifting assembly 54 facing the harvesting device 4 through the connectors 551. The plurality of pressing rollers 552 are arranged in parallel up and down. The pressing rollers 552 are mounted on the lifting assembly 54 through the connectors 551 so that the distance between the pressing rollers 552 and the lifting assembly 54 can be adjusted. The tobacco leaves are horizontally transported to the bottom of the lifting mechanism 52 by the conveying mechanism 51, and are rolled between the lifting assembly 54 and the pressing assembly 55 under the joint action of the two components, and are lifted and moved upwards until they are output from the top of the lifting mechanism 52.

[0038] like Figure 3 As shown, the harvesting device 4 includes two harvesting frames 41 and two harvesting knife assemblies 42. The two harvesting frames 41 are respectively installed on both sides of the bracket 2 so as to be movable up and down. The two harvesting knife assemblies 42 are adjustably installed on the two harvesting frames 41 in a one-to-one correspondence. The front ends of the two harvesting frames 41 along the forward direction are provided with introduction parts 43.

[0039] At the same time, in order to better collect tobacco leaves, the collection device 6 includes two collection frames 61 respectively arranged on both sides of the frame 1. The collection frame 61 includes a frame bottom 62 and a movable bar 63. The movable bar 63 is movably installed on the side of the frame bottom 62 away from the conveying device 5. The upper end of the movable bar 63 is provided with support rods 64 for hanging and supporting the collection bag on both sides of the front and rear ends. In addition, the bottom of the movable bar 63 is rotatably installed on one side of the frame bottom 62. The movable bar 63 is limitedly supported on the frame bottom 62 by a latch 65. When the collection bag needs to be removed, the latch 65 is removed and the movable bar 63 is turned downward to open, so that the staff can easily remove the collection bag. Figure 2 At the same time, an electronic scale can be installed at the bottom of the frame 62 for preliminary weighing of the collected tobacco.

[0040] For the safety and stability of the traveling work, support wheels 9 are installed at both ends of the frame 1, the front support wheel 9 is set under the seat 7, and the rear support wheel 9 is set diagonally to the front support wheel 9. At the same time, for the efficiency and intelligence of tobacco leaf harvesting, a vehicle control system 10 is provided on the frame 1 to control and connect the two driving mechanisms 31, the harvesting device 4 and the conveying device 5, and the operating device 8 is controlled and connected to the two driving mechanisms 31 through the vehicle control system 10. In addition, there is a remote control connected to the vehicle control system 10, which can flexibly control the various operations and work of the harvester in real time.

[0041] In view of the characteristics of tobacco fields in hilly and mountainous areas, the harvester's travel, power, storage and other high-quality components are all distributed at the height of the tracks. This design greatly improves the safety of the vehicle's slope driving. At the same time, it has the characteristics of miniaturization, low center of gravity, durability, strong power, and simple and reliable driving control.

[0042] After all preparations are completed, the driving mechanism 31 is started, and the remote control is used to remotely drive the harvesting vehicle into the tobacco ridge (the terrain at the end of the tobacco field in the hilly and mountainous area is complex, with ditches or slopes. Remote control driving has a good field of vision and avoids the safety hazards of manual driving at the end of the field). After entering the tobacco ridge, the driver sits in the driving seat and controls the operating device 8 to accelerate, decelerate, move forward, backward, turn left and turn right, so that it can flexibly move in the tobacco field in the hilly and mountainous area.

[0043] The harvester moves along the harvesting ridge, and the whole ridge of tobacco plants gradually passes through the middle of the harvester. The left-right symmetrical harvesting device 4 harvests the tobacco leaves that pass through the corresponding height of the tobacco plants, and the harvested tobacco leaves fall onto the conveying device 5 below. The conveying device 5 conveys the tobacco leaves to the collection bags on both sides of the collection frame 61. After the collection bags are full, the collection bags are unloaded at the end of the field. After the collection bags are full, the harvester unloads the tobacco at the end of the field, pulls out the latches 65 of the collection frames 61 on both sides, and after the latches 65 are pulled out, the movable fences 63 on both sides open outwards. After opening, the collection bags in the collection frames 61 can be taken out.

[0044] After unloading the collection bag, a new collection bag is put into the collection frame 61, and the movable fence 63 is lifted. The latch 65 is inserted, and the remote control is used to remotely drive the vehicle to turn around and enter the next adjacent ridge. The driver sits on the seat 7 and drives the vehicle using the operating device 8 to start harvesting the tobacco leaves of the entered ridge, and the process is repeated until the entire tobacco field is harvested.

[0045] The harvester has good off-road passability, a sturdy body, uniform mass distribution, strong power, a small body, flexible control and driving, and high harvesting efficiency, meeting the operational needs of tobacco fields in hilly and mountainous areas.

[0046] 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.
