Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf picking, and more specifically to a flue-cured tobacco leaf picking and collecting device. Background Art

[0002] As tobacco companies' quality requirements for tobacco leaf raw materials continue to increase, tobacco farmers need to cultivate better flue-cured tobacco plants and optimize the tobacco leaf grade structure to improve the quality of tobacco leaf harvesting. After the tobacco leaves mature, they are generally collected manually and then processed through processes such as drying.

[0003] However, manual collection is inefficient. At the same time, due to the large number of leaves on the whole plant, they need to be repeatedly transported outward, which further reduces the collection efficiency. Some methods use mechanical picking, which generally cuts the whole plant and collects it. However, the transportation method will cause the integrity of the tobacco leaves to be squeezed and damaged, which is not conducive to subsequent baking and processing. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-4The tobacco leaf picking and collecting device includes a vehicle body 1, a connecting rod 2 is fixedly installed on the front of the vehicle body 1, a connecting block 3 is fixedly installed on the upper part of the connecting rod 2, a double-headed hydraulic cylinder 4 is installed inside the connecting block 3, both ends of the double-headed hydraulic cylinder 4 extend to the outside of the connecting block 3 and are fixedly connected to a driving seat 9, a rotating disk 5 is installed on the side of the driving seat 9 away from the connecting block 3, an annular groove 6 is provided on the outside of the rotating disk 5, and an equidistantly arranged shearing mechanism 7 is installed inside the annular groove 6, and a storage bin 8 is provided on the top of the vehicle body 1.

[0022] In the present invention, the vehicle body 1 is used as the main body of the device, and the connecting rod 2 and the connecting block 3 are used as connecting supports. When in use, the vehicle body 1 is driven to move to the tobacco field (the specific driving means can be the motor in the existing mature technology as the driving source, and the energy is supplied to the driving method on the vehicle body wheel, which is not limited here), and then the double-headed hydraulic cylinder 4 is started to adjust the distance between the two rotating disks 5 so that the annular grooves 6 on them are aligned with the two rows of tobacco plants, and then the vehicle body 1 is started to move in a straight line, and the two driving seats 9 are started synchronously to drive the two rotating disks 5 to rotate. When the shearing mechanism 7 inside the rotating disk 5 rotates to the outside of a tobacco plant, the single tobacco plant is quickly cut. The tobacco leaves are cut and clamped so that they rotate backward with the rotating disk 5 to the top of the storage bin 8 and then released so that they fall into the storage bin 8 with the rotation inertia, thereby achieving the advantages of being efficient and fast, and the transportation process will not cause damage to the tobacco leaves, thereby ensuring the integrity. This solves the problem in the prior art that due to the large number of leaves in the whole plant, they need to be repeatedly transported outward, resulting in a further decrease in collection efficiency, and some of them use mechanical picking, generally the whole plant is cut and collected, and the transportation method will cause squeezing and damage to the integrity of the tobacco leaves, which is not conducive to subsequent baking and processing.

[0023] See also Figure 2 , wherein: two guide rods 91 are fixedly connected to the opposite sides of the two driving seats 9, and the opposite ends of the two guide rods 91 pass through the interior of the connecting block 3 and are slidably connected thereto.

[0024] In the present invention, the guide rod 91 makes the connection between the two driving seats 9 and the connecting block 3 more stable.

[0025] See also Figure 1 . Figure 3 and Figure 4 , wherein: the shearing mechanism 7 includes a driving cylinder 71, two clamping blocks 72 and two shearing blocks 73, the driving cylinder 71 is fixedly installed to the inside of the annular groove 6, the two clamping blocks 72 are symmetrically installed to the output part of the driving cylinder 71 and are driven thereby, and the two shearing blocks 73 are respectively hingedly arranged at the bottom of the two clamping blocks 72.

[0026] In the present invention, by starting the driving cylinder 71, the clamping block 72 and the shearing block 73 are driven to perform a shearing action. The shearing block 73 at the bottom first contacts and shears the tobacco plant. As the clamping block 72 approaches and contacts the tobacco plant to clamp it, the shearing block 73 completely cuts it off. Then the clamping block 72 clamps the tobacco and transports it as it rotates, without contacting the tobacco leaves, thereby effectively protecting the integrity of the tobacco leaves.

[0027] See also Figure 3 and Figure 4 , wherein: opposite sides of the two shear blocks 73 are fixedly connected with staggered corresponding blades 731.

[0028] In the present invention, two staggered blades 731 are used to achieve fast and accurate cutting operations.

[0029] See also Figure 3 and Figure 4 , wherein: an open movable groove 721 is opened at the bottom of the clamping block 72, the shear block 73 is located inside the movable groove 721, a spring 722 is fixedly connected to the inside of the movable groove 721, and the other end of the spring 722 is fixedly connected to the shear block 73.

[0030] In the present invention, the spring 722 inside the movable groove 721 maintains the thrust on the shear block 73, and in the process of the clamping block 72 gradually clamping and approaching, the two shear blocks 73 will not be subjected to excessive force and will be buffered by the spring 722, thereby achieving the effect of shearing first and then clamping, while protecting the structure of the shear block 73.

[0031] See also Figure 4 , wherein: elastic rubber layers 74 are fixedly connected to opposite sides of the two clamping blocks 72.

[0032] In the present invention, the elastic rubber layer 74 provides a better clamping effect, thereby preventing the tobacco plants from being damaged or falling due to excessive clamping force.
