Description

Technical Field

[0001] This utility model relates to a tobacco harvesting device, specifically a vertically layered tobacco harvesting device, belonging to the field of tobacco harvesting technology. Background Technology

[0002] Tobacco harvesting is a heavy and arduous physical labor activity, and manual harvesting is inefficient and not conducive to timely harvesting of tobacco leaves. To solve this problem, several fully automatic tobacco harvesting machines have been introduced in recent years.

[0003] The harvesting device used in a fully automatic tobacco harvester is a key factor in determining the quality of harvested tobacco leaves. Currently, the main harvesting devices include plate-type harvesting devices and rotary arc-type leaf-beating devices. The characteristics of these harvesting devices are non-linear contact and repeated striking methods. During the harvesting process, the leaf surface is repeatedly struck, resulting in a high breakage rate of harvested tobacco leaves and significant harvesting losses. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the technical problem that existing harvesting devices repeatedly strike the leaf surface. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a vertically layered tobacco leaf harvesting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vertically layered tobacco harvesting device includes a first part and a second part with symmetrical structure, and both the first part and the second part include a leaf-picking device and a pushing device.

[0007] The leaf-plucking device includes a leaf-plucking frame and a linear bearing fixing bracket. The leaf-plucking frame includes a first L-shaped frame, a second L-shaped frame, and a connecting rod. One end of the first L-shaped frame and the second L-shaped frame are respectively connected to both ends of the connecting rod. A leaf-plucking rubber finger is provided on one side of the connecting rod. A tobacco inlet plate is provided on the outer side of one end of the first L-shaped frame. The other ends of the first L-shaped frame and the second L-shaped frame are respectively fixedly connected to both ends of the linear bearing fixing bracket. A transmission connecting plate is connected to the linear bearing fixing bracket.

[0008] The pushing device includes a track fixing plate, a drive motor, a rotating arm, a transmission rod, a first transmission bearing, a second transmission bearing, a first cylindrical track, a second cylindrical track, a first linear sliding bearing, a second linear sliding bearing, and a cylindrical track fixing rod.

[0009] The track mounting plate is fixedly connected to the drive motor, the drive motor is connected to the rotating arm, the rotating arm is connected to one end of the transmission rod through the second transmission bearing, and the other end of the transmission rod is connected to the upper end of the transmission connecting plate through the first transmission bearing.

[0010] One side of the track fixing plate is fixedly connected to one end of the first cylindrical track, and the other end of the first cylindrical track is fixedly connected to one end of the cylindrical track fixing rod. A first linear sliding bearing is sleeved on the first cylindrical track, and the first linear sliding bearing is connected to one side of the linear bearing fixing bracket.

[0011] The other side of the track fixing plate is fixedly connected to one end of the second cylindrical track, and the other end of the second cylindrical track is fixedly connected to the other end of the cylindrical track fixing rod. A second linear sliding bearing is fitted on the second cylindrical track, and the second linear sliding bearing is connected to the other side of the linear bearing fixing bracket.

[0012] As a further improvement of this utility model, the linear bearing fixing bracket is vertically fixedly connected to the lower end of the transmission connecting plate, and there are multiple linear bearing fixing brackets to ensure the stable operation of the leaf-picking device during the harvesting process.

[0013] As a further improvement of this utility model: the transmission connecting plate is provided with multiple harvesting layer height positioning holes, which are connected to the transmission rod through the first transmission bearing, so that the height of the leaf-picking device can be adjusted to realize the harvesting of tobacco leaves at different vertical heights.

[0014] As a further improvement of this utility model, the rotating arm is provided with multiple harvesting layer thickness positioning holes, which are connected to the transmission rod through the second transmission bearing, thereby adjusting the harvesting thickness of the leaf-picking device to meet different harvesting needs.

[0015] As a further improvement of this utility model: the first part and the second part of the leaf-plucking rubber fingers correspond to each other and together form a leaf-plucking claw. The leaf-plucking rubber fingers are rectangular teeth, which are evenly distributed on the outside of the connecting rod. The evenly distributed rectangular tooth structure can more effectively pluck tobacco leaves and improve harvesting efficiency.

[0016] As a further improvement of this utility model, the tobacco plant guide plate is a fan-shaped plate, which is set at the outer entrance of one end of the first L-shaped frame. The design of the fan-shaped plate helps the tobacco plants enter the harvesting device more smoothly.

[0017] As a further improvement of this utility model, the tobacco plant guide plates of the first and second parts form an "outward V-shaped" inlet. The outward V-shaped inlet can more easily guide the tobacco plants into the device and improve the convenience of harvesting.

[0018] The beneficial effects of this utility model are:

[0019] (1) The rectangular toothed rubber fingers on the leaf-plucking device can more effectively pluck the tobacco leaves, and the first part and the second part of the corresponding rubber fingers form leaf-plucking claws, ensuring that the tobacco leaves are stably plucked, reducing multiple contacts with the tobacco leaves, and improving harvesting efficiency; the pushing device can continuously and smoothly output thrust so that the leaf-plucking device moves linearly and vertically up and down along the first cylindrical track and the second cylindrical track, which can effectively pluck the tobacco leaves vertically layer by layer from top to bottom in one go; the multiple harvesting layer height positioning holes on the transmission connecting plate can adjust the harvesting of tobacco leaves at different vertical heights; the multiple harvesting layer thickness positioning holes on the rotating arm can adjust the harvesting thickness of the leaf-plucking device, meet different harvesting needs, and improve the flexibility and versatility of the device.

[0020] (2) This utility model uses a pushing device to push the leaf-plucking device to perform a vertical downward pressing action, which can peel off the tobacco leaves from the tobacco plant layer by layer in one go from top to bottom. It can also efficiently and stably vertically press down to harvest tobacco leaves of different layers and thicknesses. The leaves peeled off vertically by this device are intact and do not make secondary contact with individual tobacco leaves, reducing tobacco leaf damage and improving harvesting convenience and applicability.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1, as Figures 1 to 6 As shown in the figure, this embodiment provides a vertically layered tobacco harvesting device, which includes a first part and a second part with symmetrical structure. Both the first part and the second part include a leaf-plucking device and a pushing device.

[0036] The blade-cutting device includes a blade-cutting frame 1 and a linear bearing fixing bracket 4. The blade-cutting frame 1 consists of a first L-shaped frame 101, a second L-shaped frame 102, and a connecting rod 103. One end of the first L-shaped frame 101 and the second L-shaped frame 102 are welded to both ends of the connecting rod 103, forming a rectangular frame structure. Blade-cutting rubber fingers 2 are evenly distributed on the outside of the connecting rod 103. These blade-cutting rubber fingers have a rectangular tooth structure and are made of natural rubber, possessing good elasticity and wear resistance.

[0037] A fan-shaped tobacco guide plate 3 is fixedly installed on the outer side of one end of the first L-shaped frame 101. The upper ends of the first L-shaped frame 101 and the second L-shaped frame 102 in the vertical direction are fixedly connected to both ends of the linear bearing fixing bracket 4 by bolts. The linear bearing fixing bracket 4 is connected to a transmission connecting plate 5, and the lower end of the linear bearing fixing bracket 4 is vertically welded to the transmission connecting plate 5. In this embodiment, two parallel linear bearing fixing brackets 4 are provided to enhance structural stability.

[0038] The pushing device includes a track fixing plate 14, a drive motor 15, a rotating arm 12, a transmission rod 11, a first transmission bearing 111, a second transmission bearing 112, a first cylindrical track 91, a second cylindrical track 92, a first linear sliding bearing 81, a second linear sliding bearing 82, and a cylindrical track fixing rod 7.

[0039] The track mounting plate 14 is fixedly connected to the drive motor 15 by bolts. The drive motor 15 is fixedly connected to one end of the rotating arm 12, which can drive the rotating arm 12 to rotate.

[0040] The rotating arm 12 is connected to one end of the transmission rod 11 via the second transmission bearing 112, and the other end of the transmission rod 11 is connected to the upper end of the transmission connecting plate 5 via the first transmission bearing 111.

[0041] One side of the track mounting plate 14 is fixedly connected to one end of the first cylindrical track 91, and the other end of the first cylindrical track 91 is also fixedly connected to the cylindrical track fixing rod 7. A first linear sliding bearing 81 is sleeved on the first cylindrical track 91, and the first linear sliding bearing 81 is fixedly connected to one side of the linear bearing fixing bracket 4 by bolts.

[0042] The other side of the track fixing plate 14 is fixedly connected to one end of the second cylindrical track 92 of the same specification. The other end of the second cylindrical track 92 is fixedly connected to the other end of the cylindrical track fixing rod 7. The second cylindrical track 92 is fitted with a second linear sliding bearing 82 of the same model. The second linear sliding bearing 82 is connected to the other side of the linear bearing fixing bracket 4.

[0043] When the tobacco plant enters the middle position of the left and right leaf-picking devices, the on-board sensors are activated, and the on-board computer drives the drive motor 15 of the harvesting device. Figure 3 As shown, when the drive motors 15 on both sides rotate clockwise synchronously, they drive the rotating arm 12, which in turn drives the transmission connecting plate 5 through the transmission rod 11 and the transmission bearing 112, causing the entire blade-scraping device to move vertically upward along the first cylindrical track 91 and the second cylindrical track 92 to a high position. Then, the drive motors 15 continue to rotate clockwise, as... Figure 4 As shown, at this point, the leaf-plucking device begins to move vertically downwards, generating a downward thrust to pluck the tobacco leaves in the harvesting layer of the tobacco plant that is passing through in one go. After the leaf-plucking is completed, the leaf-plucking device reaches its original lowest point and then repeats the initial action. The leaf-plucking device gradually rises and returns to the highest position. At this time, the drive motor 15 brakes, allowing the leaf-plucking device to stop at the horizontal level above the harvesting layer, that is, return to the highest position, waiting for the next tobacco plant to enter the leaf-plucking device to begin leaf-plucking. This process is repeated until the harvesting of the entire row of tobacco is completed.

[0044] Example 2, as Figures 1 to 6 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0045] The transmission connecting plate 5 is provided with multiple harvesting layer height positioning holes 6. By selecting different harvesting layer height positioning holes 6 to connect with the first transmission bearing 111, the harvesting height can be adjusted within a different range.

[0046] The rotating arm 12 is provided with multiple harvesting layer thickness positioning holes 13. By selecting different harvesting layer thickness positioning holes 13 and connecting them with the second transmission bearing 112, the harvesting thickness can be adjusted within a range of different thicknesses.

[0047] The first and second parts of the leaf-picking rubber fingers 2 correspond to each other and together form the leaf-picking claw structure. When the two parts move relative to each other, the tobacco leaves can be clamped and picked.

[0048] The first and second sections of the tobacco plant guide plate 3 form an external "V" shaped tobacco plant inlet 16 with an opening angle of 90 degrees, which facilitates the entry of tobacco plants into the harvesting device.

[0049] When in use, the device is installed on a mobile frame. The harvesting height is determined by adjusting the position of the transmission bearing 111 in the harvesting layer height positioning hole 6 according to the growth height of the tobacco leaves. Alternatively, the harvesting thickness can be determined by adjusting the position of the transmission bearing 112 in the harvesting layer thickness positioning hole 13 according to the thickness of the tobacco leaves.

[0050] Start the drive motor 15, which drives the rotating arm 12 to rotate. The drive motor 15 then drives the transmission connecting plate 5 to move via the transmission rod 11, thereby driving the linear bearing fixing bracket 4 and the blade frame 1 to reciprocate linearly along the cylindrical track 91 and the cylindrical track 92.

[0051] When the tobacco plants enter the device through the outward-facing inlet 16, the leaf-plucking rubber fingers 2 of the first and second parts open and close relative to each other, plucking the tobacco leaves off the tobacco plants and realizing mechanized harvesting of tobacco leaves.

[0052] The vertical stratified tobacco harvesting device of this embodiment can realize stratified harvesting of tobacco leaves, reduce tobacco leaf damage, improve harvesting efficiency, and is suitable for harvesting tobacco leaves of different varieties and growth conditions.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
