[0023] Figure 1 This schematic diagram illustrates the structure of a tobacco leaf harvesting device according to one embodiment of the present invention. Figure 2 This schematic diagram illustrates the structure of a first walking component according to one embodiment of the present invention. Figure 3 This schematic diagram illustrates the structure of the second walking component according to one embodiment of the present invention, as shown below. Figure 1-3 As shown, this utility model discloses a tobacco leaf harvesting device with an adjustable picking position, comprising: First walking assembly 10, second walking assembly 20 and sunshade 30; The first walking component 10 and the second walking component 20 are parallel to each other and spaced apart. The first walking component 10 and the second walking component 20 are used to move forward and backward synchronously. The space between the first walking component 10 and the second walking component 20 is used for tobacco plants to pass through. The first walking assembly 10 includes a first mounting frame 101 and a first seat 102. The first seat 102 is slidably connected to the top of the first mounting frame 101 and is capable of moving toward and away from the second walking assembly 20. The second walking assembly 20 includes a second mounting frame 201 and a second seat 202.

[0024] When in use, the user sits in the seat and controls the tobacco leaf collection device to move. The tobacco plants pass through the space between the first walking component 10 and the second walking component 20. The user picks the tobacco leaves from the passing tobacco plants and places them on the first mounting frame 101 and the second mounting frame 201.

[0025] By sliding the first seat 102 and the second seat 202, the user can freely adjust the position of the first seat 102 and the second seat 202 according to the walking position of the tobacco leaf collection device and the size of the tobacco plant, such as plant height and plant spacing, so that they are closer to or further away from the tobacco plant, thereby making it easier for the user to pick the tobacco leaves and improving the efficiency of tobacco leaf harvesting.

[0026] Furthermore, Figure 4 This diagram schematically illustrates the structure of the first limiting structure according to one embodiment of the present invention. Figure 5 This schematic diagram illustrates the structure of the second limiting structure according to one embodiment of the present invention, as shown below. Figure 4 , 5 As shown: The first walking assembly 10 also includes a first slide groove 103, a first slider 104 and a first limiting structure 105. The first slide groove 103 is disposed on the top of the first mounting bracket 101 and located at one end of the first mounting bracket 101. The first slide groove 103 is fixedly connected to the first mounting bracket 101. The first slider 104 is disposed on the bottom of the first seat 102 and fixedly connected to it. The first slider 104 is used to insert into the first slide groove 103 and slide along the first slide groove 103.

[0027] The first limiting structure 105 includes a first limiting hole 1051, a second limiting hole 1052 and a first locking bolt 1053. The first limiting hole 1051 is disposed on the side wall of the first slide groove 103 and penetrates the first slide groove 103. The second limiting hole 1052 is disposed on the side wall of the first slider 104 and penetrates the first slider 104. Multiple first limiting holes 1051 are provided. When the first slider 104 moves to make the first limiting hole 1051 correspond to the second limiting hole 1052, the first locking bolt 1053 is inserted in sequence to limit the displacement of the first seat 102.

[0028] Similarly, the second walking assembly 20 also includes a second slide groove 203, a second slider 204, and a second limiting structure 205. The second slide groove 203 is disposed on the top of the second mounting bracket 201 and located at one end thereof. The second slide groove 203 is fixedly connected to the second mounting bracket 201. The second slider 204 is disposed on the bottom of the second seat 202 and fixedly connected thereto. The second slider 204 is used to insert into the second slide groove 203 and slide along the second slide groove 203. The second limiting structure 205 includes a third limiting hole 2051, a fourth limiting hole 2052, and a second locking bolt 2053. The third limiting hole 2051 is disposed on the side wall of the second slide groove 203 and penetrates the second slide groove 203. The fourth limiting hole 2052 is disposed on the side wall of the second slider 204 and penetrates the second slider 204. Multiple third limiting holes 2051 are provided. When the second slider 204 moves to make the third limiting hole 2051 and the fourth limiting hole 2052 correspond, the second locking bolt 2053 is inserted in sequence to limit the displacement of the second seat 202.

[0029] With the above settings, taking the first walking component 10 as an example, when the user sits on the first seat 102, by controlling the movement of the first seat 102, the first slider 104 is driven to slide in the first slide groove 103, thereby changing the position of the first seat 102, which can move closer to or away from the tobacco plant, making it more convenient for the user to pick tobacco leaves. Meanwhile, once the first seat 102 is in place, the first locking bolt 1053 is sequentially inserted into the first limiting hole 1051 and the second limiting hole 1052, thereby restricting the movement of the first seat 102 and fixing the first seat 102 to the first mounting bracket 101, thus achieving adjustment of the picking position.

[0030] Similarly, the operation method of the second walking component 20 is the same as described above.

[0031] Furthermore, for easier use and operation, the first limiting structure 105 also includes a first connecting rod 1054, a second connecting rod 1055, and a first collar 1056; The first connecting rod 1054 is fixed and vertically connected to the first slider 104. The first connecting rod 1054 passes through the first collar 1056. The first collar 1056 is slidably connected to the first connecting rod 1054. The second connecting rod 1055 is fixedly connected to the circumferential side wall of the first collar 1056. The first locking bolt 1053 is perpendicular to and fixedly connected to the second connecting rod 1055. The first collar 1056 is used to control the insertion or extension of the first locking bolt 1053 into the first limiting hole 1051 and the second limiting hole 1052.

[0032] Similarly, the second limiting structure 205 also includes a third connecting rod 2054, a fourth connecting rod 2055, and a second collar 2056; The third connecting rod 2054 is fixed and vertically connected to the second slider 204. The third connecting rod 2054 passes through the second collar 2056. The second collar 2056 is slidably connected to the third connecting rod 2054. The fourth connecting rod 2055 is fixedly connected to the circumferential side wall of the second collar 2056. The second locking bolt 2053 is perpendicular to and fixedly connected to the fourth connecting rod 2055. The second collar 2056 is used to control the insertion or extension of the second locking bolt 2053 into the third limiting hole 2051 and the fourth limiting hole 2052.

[0033] Specifically, taking the first walking assembly 10 as an example, the first connecting rod 1054 is arranged around the second limiting hole 1052, and the length of the distance between the center of the first connecting rod 1054 and the center of the second limiting hole 1052 is equal to the length of the second connecting rod 1055, so that the first locking bolt 1053 corresponds to the position of the second limiting hole 1052. When the first collar 1056 moves axially along the first connecting rod 1054, the second connecting rod 1055 moves synchronously, which enables the first locking bolt 1053 to be inserted into or extended from the first limiting hole 1051 and the second limiting hole 1052, thereby realizing the fixation of the first seat 102. This integrated design of the first locking bolt 1053 and the first seat 102 avoids the problem of the first locking bolt 1053 being lost or falling off, so that the user does not need to hold the first locking bolt 1053 separately, thus providing convenience for the user.

[0034] Similarly, the second walking component 20 is configured the same as the first walking component 10.

[0035] Furthermore, a first handle 1057 can be provided on the first ring 1056 and a second handle 2057 can be provided on the second ring 2056, which can make it more convenient for users to hold and control, and further improve the comfort of use.

[0036] Furthermore, Figure 6This schematic diagram illustrates the installation of the fifth and sixth connecting rods according to one embodiment of the present invention, as shown below. Figure 6 As shown: The sunshade 30 includes a frame 301, a fifth connecting rod 302, a sixth connecting rod 303, and a third locking bolt 304; The fifth connecting rod 302 is respectively disposed on the first mounting frame 101 and the second mounting frame 201. The top of the sixth connecting rod 303 is fixedly connected to the frame 301, and the bottom is sleeved with the fifth connecting rod 302 and slidably connected to the fifth connecting rod 302. The fifth connecting rod 302 is provided with a plurality of spaced fifth limiting holes 3021, and the sixth connecting rod 303 is provided with a sixth limiting hole 3031. The fifth limiting hole 3021 passes through the fifth connecting rod 302, and the sixth limiting hole 3031 passes through the sixth connecting rod 303. When the sixth connecting rod 303 is moved so that the sixth limiting hole 3031 corresponds to the fifth limiting hole 3021, the third locking bolt 304 is used to sequentially insert the fifth limiting hole 3021 and the sixth limiting hole 3031 so that the fifth connecting rod 302 and the sixth connecting rod 303 are fixedly connected.

[0037] By freely adjusting the sixth limiting hole 3031 to correspond with the fifth limiting hole 3021 at different positions and fixing it with the third locking bolt 304, the height of the frame 301 can be adjusted. The frame 301 can be set as a whole flat plate to achieve sunshade and rain protection functions, or a curtain can be placed on the frame 301 to achieve sunshade and rain protection, and custom adjustment can be achieved.

[0038] Furthermore, at least one fifth connecting rod 302 and one sixth connecting rod 303 are provided, preferably two of each.

The first track 108 is wound around the first drive wheel 106 and the first road wheel 107 to realize the transmission of the first drive wheel 106 and the first road wheel 107. The first drive wheel 106 and the first road wheel 107 are respectively located at both ends of the first mounting frame 101. The first drive wheel 106 is used to control the rotation of the first track 108 to move the first walking assembly 10, while the first road wheel 107 is a driven wheel used to support the first mounting frame 101 and its components. The first drive wheel 106 is powered by a power source (not shown in the figure) and can provide power to drive the first drive wheel 106 to rotate to realize walking.

[0040] Similarly, a second drive wheel 206, a second road wheel 207, and a second track 208 are provided at the bottom of the second mounting frame 201. The second track 208 is wound around the second drive wheel 206 and the second road wheel 207 to realize the transmission between the second drive wheel 206 and the second road wheel 207. The second drive wheel 206 and the second road wheel 207 are respectively provided at both ends of the second mounting frame 201. The second drive wheel 206 is used to control the rotation of the second track 208 to move the second walking assembly 20.

[0041] Furthermore, a first guardrail 109 is provided on the top of the first mounting frame 101, and the first guardrail 109 is provided on the side of the first mounting frame 101 away from the first seat 102 and on the adjacent two sides. The top of the second mounting bracket 201 is provided with a second guardrail 209, which is located on the side of the second mounting bracket 201 away from the second seat 202 and on the adjacent two sides.

[0042] Specifically, the first guardrail 109 and the second guardrail 209 are configured with a U-shaped structure. When the user sits on the seat and picks the tobacco leaves, he places them on the first mounting frame 101 and the second mounting frame 201.
