Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to an automatic tobacco leaf-cutting device for collecting and cutting leaves. Background Technology

[0002] During the tobacco seedling stage, the leaves of the seedlings are pruned to improve their quality, enhance their adaptability, and adjust their morphology. Pruning promotes root growth, ensures balanced growth of individual seedlings, controls early flowering, and improves the survival rate of transplanted seedlings.

[0003] In existing technologies, leaf trimming machines are typically used for thinning. These machines are usually suspended above the tobacco seedlings using a mobile frame, and rotating blades trim the seedlings. The trimmed leaves are discharged from the machine's discharge port by airflow. A receiving device is installed behind the discharge port for easy collection of leaf fragments. However, in actual use, the high airflow at the discharge port still causes some leaf fragments to splash onto the seedlings, damaging them. After trimming, the scattered leaf fragments also need to be washed, increasing the workload.

[0004] In addition, existing receiving devices need to be separated from the leaf trimming machine before they can be cleaned. For example, a tobacco seedling leaf trimming residue collection device disclosed in CN222030611U uses a collection hopper for collection. During cleaning, the connection between the first and second connecting parts needs to be disconnected, otherwise the leaf trimming mechanism will block the collection hopper. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic tobacco leaf-cutting device for collecting and cutting leaves.

[0006] The technical solution of this utility model is:

[0007] An automatic tobacco leaf-cutting device for collecting cut leaves includes:

[0025] 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.

[0026] Example 1:

[0027] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] An automatic tobacco leaf-cutting device for collecting cut leaves includes:

[0029] Leaf trimming assembly 2 includes a leaf trimmer 25. A lateral moving device is connected to the top of the leaf trimmer 25 to drive it to move laterally. A discharge hood 26 is provided behind the leaf trimmer 25. A collection assembly 3 is connected to the discharge hood 26. The collection assembly 3 includes a collection hopper 31. A baffle device is provided in front of the collection hopper 31 to block splashed leaf fragments. A moving assembly 1 is provided outside the leaf trimmer assembly 2 and the collection assembly 3. The moving assembly 1 includes a lifting device to adjust the height of the leaf trimmer assembly 2 and the collection assembly 3.

[0030] The lifting device includes a movable frame 11, a lifting frame 13 is slidably mounted on the top surface of the movable frame 11, and a drive structure is provided between the lifting frame 13 and the movable frame 11. The drive structure is used to drive the lifting frame 13 to move.

[0031] The drive structure includes a first threaded sleeve 14, which is welded to the middle of the top surface of the movable frame 11. A first screw 15 is installed on the inner thread of the first threaded sleeve 14. The top of the first screw 15 passes through the middle of the lifting frame 13 and is rotatably connected to the lifting frame 13.

[0032] By driving the first screw 15 to rotate, the first threaded sleeve 14 can be driven to move along the axis of the first screw 15, thereby driving the lifting frame 13 to move in the vertical direction.

[0033] The bottom surface of the movable frame 11 is rotatably mounted with movable wheels 12, and two movable frames 11 on the same side are fixedly connected by a connecting rod 16.

[0034] The connecting rod 16 can be a double-ended screw, and the connecting rod 16 is threadedly connected to both the front and rear movable frames 11 to achieve a rigid connection between the front and rear movable frames 11.

[0035] The lateral movement device is fixedly installed on top between the two front lifting frames 13.

[0036] The lateral movement device includes two guide rods 21, which are symmetrically engaged and mounted on the tops of the two front lifting frames 13. A mounting frame 22 is provided above the guide rods 21, and guide wheels 23 are rotatably mounted on the top inner side of the mounting frame 22, with the guide wheels 23 rollingly connected to the guide rods 21. Two of the guide wheels 23 are connected to a first power source 24.

[0037] The first power source 24 can be connected by two shafts. When the first power source 24 is working, it can drive the guide wheel 23 to rotate, thereby driving the mounting frame 22 to move along the axis of the guide rod 21.

[0038] The bottom of the mounting bracket 22 is located below the guide rod 21, and the leaf trimmer 25 is fixedly mounted on the bottom of the mounting bracket 22 by bolts.

[0039] The leaf trimmer 25 can be a known lawnmower, which trims tobacco seedlings by rotating blades.

[0040] The discharge cover 26 is fixedly installed on the rear side of the leaf shearing machine 25 by screws.

[0041] The hopper 31 is fixedly installed between the two lifting frames 13 on the rear side by screws, and a back plate 32 is snapped onto the rear side of the hopper 31.

[0042] The back plate 32 can slide vertically and be pulled out from above the hopper 31, thereby opening the rear side of the hopper 31.

[0043] The material blocking device includes a material blocking curtain 34, which is fixedly installed on the front side of the material collecting hopper 31 by a fixing frame 33. The material blocking curtain 34 is made of flexible material, and the discharge cover 26 passes through the material blocking curtain 34 and is inserted into the inside of the material collecting hopper 31.

[0044] The baffle curtain 34 can be composed of several cylindrical rubber strips arranged in parallel. The top of the baffle curtain 34 is inserted into the fixing frame 33, which is fixedly installed on the top front side of the collecting hopper 31 by screws. The bottom end of the baffle curtain 34 contacts the inner top surface of the collecting hopper 31.

[0045] The bottom surface of the discharge hood 26 is slidably connected to the inner bottom surface of the collection hopper 31.

[0046] When the discharge hood 26 is inserted into the collection hopper 31, the bottom of the baffle curtain 34 that is in contact with the discharge hood 26 will bend backward, while the remaining part remains stationary.

[0047] When the leaf trimmer 25 is working, the trimmed leaf fragments can enter the collection hopper 31 from the discharge hood 26 along with the airflow. The airflow and leaf fragments are blocked by the baffle curtain 34, thus preventing them from flying out of the collection hopper 31.

[0048] Limiting frames 36 are slidably installed at both ends of the fixed frame 33 via sliding rods 35. Fixing bolts 37 are provided on the outer sides of both ends of the limiting frame 36. The fixing bolts 37 pass through the limiting frame 36 and abut against the sliding rods 35. The limiting frame 36 clamps the middle of the baffle curtain 34.

[0049] After loosening the fixing bolt 37, the limiting frame 36 can slide along the sliding rod 35, thereby changing its own height. At the same time, the length of the baffle curtain 34 below the limiting frame 36 will also change.

[0050] By changing the length of the baffle curtain 34 below the limit frame 36, the movement of the discharge hood 26 is allowed while avoiding it from being blown away by the airflow due to excessive length, thus further ensuring that the broken leaves will not splash.

[0051] In this embodiment, when the operator uses this equipment, the moving wheel 12 moves the moving component 1 above the nursery, controls the first screw 15 to rotate, drives the lifting frame 13 to move, thereby controlling the height of the leaf trimmer 25 and the collection hopper 31, and controlling the trimming height.

[0052] The leaf trimmer 25 is controlled to work, and the moving component 1 is also controlled to move to trim the tobacco seedlings.

[0053] During the movement, the first power source 24 is controlled to work, driving the leaf trimmer 25 to reciprocate along the guide rod 21, covering a larger area.

[0054] When the leaf trimmer 25 is working, it can trim excess tobacco seedlings. The trimmed leaf fragments can enter the discharge hood 26 with the airflow and then be discharged from the discharge hood 26 into the collection hopper 31.

[0055] After the airflow and debris enter the collecting hopper 31, they will flow along the inner wall of the collecting hopper 31 until they are blocked by the baffle curtain 34.

[0056] When there is too much waste in the collection hopper 31, first stop the leaf trimmer 25, then remove the back plate 32 and clean the waste in the collection hopper 31. After cleaning, reinstall the back plate 32 in its original position, and the trimming work can continue.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
