Abstract
Description
Technical Field
[0001] The invention relates to the field of tobacco leaf picking, in particular to an upper tobacco leaf segmented stem picking device and a picking method thereof. Background Art
[0002] Tobacco is an important economic crop. In the process of tobacco production, harvesting is a basic work. The harvesting period and method of tobacco leaves are related to the tobacco yield and quality. Therefore, scientific and timely harvesting of tobacco leaves is the key to ensuring the quality of tobacco leaves. When harvesting tobacco leaves, the vast majority of tobacco farmers in my country still harvest them manually, which not only consumes a lot of labor and time, but also has low harvesting efficiency and it is difficult to ensure timely harvesting.
[0003] The existing tobacco leaf harvesting method is mostly that the tobacco farmer carries a tobacco basket on his back, then uses electric scissors to cut the tobacco leaves according to actual needs and place the tobacco leaves in the tobacco basket on his back. During the cutting process, the tobacco farmer needs to bend back and forth, which wastes a lot of labor of the tobacco farmer, resulting in a decrease in the cutting efficiency of subsequent staff. At the same time, manual picking of tobacco leaves is difficult to ensure the best harvesting time of the tobacco leaves, which will affect the overall quality of the subsequent tobacco leaves.
[0004] In summary, the above structure requires tobacco farmers to bend back and forth during the actual picking process, which reduces the shearing efficiency of subsequent workers and makes it difficult to ensure the optimal harvesting time of tobacco leaves, affecting the overall quality of subsequent tobacco leaves. Summary of the invention
[0005] Based on this, the purpose of the present invention is to provide an upper tobacco leaf segmented stem picking device and a picking method thereof, so as to solve the technical problem that tobacco farmers are required to perform reciprocating bending work during the actual picking process, resulting in a decrease in the cutting efficiency of subsequent staff, and it is difficult to ensure the optimal harvesting time of tobacco leaves, thereby affecting the overall quality of subsequent tobacco leaves.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an upper tobacco leaf segmented stem picking device, comprising a vehicle body and a picking mechanism, the picking mechanism being slidably arranged on one side of the vehicle body, one end of the picking mechanism being connected to an electric slider that slides with the vehicle body, one end of the electric slider being elastically provided with a second guide column, and an adjusting gear being rotatably arranged in the electric slider, one end of the adjusting gear being connected to a worm gear through a transmission assembly, and one end of the worm gear being connected to the picking mechanism;
[0007] A first guide column that cooperates with a second guide column is elastically arranged in the vehicle body, and a column is elastically arranged on one side of the first guide column, a first tooth block is arranged on one side of the column, and a fixed gear is rotatably arranged on one side of the first tooth block, a collecting bin is opened in the vehicle body, and a cover plate that cooperates with the fixed gear is rotatably arranged on the top of the collecting bin.
[0008] By adopting the above technical solution, when the electric slider moves to the first guide post, the second guide post squeezes the first guide post to one side under the action of the elastic component. At this time, the second tooth block on the second guide post will drive the adjusting gear to rotate. Through the cooperation between the transmission components, the picking mechanism is rotated and adjusted as a whole. At this time, the clamping plate can be rotated to the bottom. When the first guide post is squeezed by the second guide post, the column will drive the first tooth block to move downward, thereby driving the fixed gear to rotate, thereby releasing the sealing work of the baffle door on the collecting bin, and realizing that the cover plate at the collecting bin is automatically opened after the picking is completed, and the cover plate is subsequently reset to seal the collecting bin again.
[0009] The present invention is further configured such that an electric slide groove for cooperation with the electric slider is provided on one side of the vehicle body, and the first guide column is protrudingly disposed in the electric slide groove in a normal state.
[0010] Preferably, the vehicle body can adjust the overall height of the picking mechanism through the cooperation of the electric slide and the electric slider, so that it is suitable for picking tobacco leaves of different heights, further improving the overall practicality of the device.
[0011] The present invention is further configured such that a plurality of second gear blocks meshing with the adjusting gear are arranged on the top of the second guide column, and an elastic component is connected to one end of the second guide column.
[0012] Preferably, when the second guide post moves to the first guide post, the first guide post is squeezed so that the second guide post drives the second tooth block on the top to slide, thereby driving the adjusting gear to rotate, and the setting of the elastic component facilitates the second guide post to slide stably laterally.
[0013] The present invention is further configured such that one end of the adjusting gear is connected to a transmission mechanism, and the other end of the transmission mechanism is connected to a worm, and the bottom of the worm is meshed with the worm wheel.
[0014] Preferably, the transmission mechanism is driven to rotate during the rotation of the adjusting gear, thereby causing the worm at the other end of the transmission mechanism to rotate. Since the worm and the worm wheel are meshed with each other, the worm wheel will also rotate as the worm rotates.
[0015] The present invention is further configured such that the picking mechanism includes a controller, a clamping plate and electric scissors, the electric scissors are arranged on one side of the controller, and the clamping plate is connected to the top of the electric scissors.
[0016] Preferably, when the picking mechanism is moved to a specified height by the action of an electric slider, the controller controls the clamping plate to clamp the upper part of the tobacco leaves, and then the tobacco leaves are cut by the action of electric scissors. At this time, the clamping plate can clamp and limit the cut tobacco leaves, effectively preventing the tobacco leaves from falling, and further reducing the burden of subsequent tobacco leaf collection.
[0017] The present invention is further configured such that the transmission mechanism includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the adjusting gear is connected to the driving disk, and one end of the driven disk is connected to the worm, and the diameter of the driving disk in the transmission mechanism is larger than the diameter of the driven disk.
[0018] Preferably, when the adjusting gear rotates under the action of the second guide column, the active disk at one end will be driven to rotate, and the driven disk will follow the rotation under the action of the transmission belt, thereby realizing the follow-up rotation of the worm. Since the diameter of the active disk in the transmission mechanism is larger than the diameter of the driven disk, when the adjusting gear rotates a certain angle during the rotation process, the worm will rotate several times the number of circles, ensuring that the subsequent picking mechanism can rotate stably.
[0019] The present invention is further configured such that a blocking door is provided at one side of the collecting bin at the front end of the vehicle body, and a cover plate groove for the cover plate to be inserted is provided on the vehicle body.
[0020] As a preferred embodiment, the collection bin can be shielded by the baffle door, and subsequent staff can open the baffle door to take out the tobacco leaves collected inside. The cover groove on the vehicle body ensures that when the cover is flipped, it can fit with the side wall of the vehicle body to ensure the overall flatness of the vehicle body.
[0021] The present invention is further configured such that a detection probe is provided at the front end of the vehicle body, and a plurality of universal wheels are symmetrically provided at the bottom of the vehicle body.
[0022] Preferably, the detection probe facilitates the detection of the overall height of the tobacco leaves and the movement of the picking mechanism to a specified height, thereby further improving the overall picking efficiency. Meanwhile, the universal wheels at the bottom facilitate the stable sliding of the vehicle body in the tobacco leaves.
[0023] A method for picking upper tobacco leaves in sections with stems comprises the following steps:
[0024] Step 1: Move the whole device to the designated position through the universal wheels at the bottom of the vehicle body, then detect the area of the tobacco leaves to be sheared by the detection probe, and move the clamping plate and the electric scissors to the tobacco leaves together;
[0025] Step 2: Use the blade of electric scissors to clamp the lower end of the upper excess stems. The upper excess stems are located above 0.5 cm above the horseshoe-shaped petiole groove of the upper leaf. Cut them off with the electric scissors so that the shearing surface is a horizontal circle. Use the same method to cut off the lower excess stems. The lower excess stems are located below 0.5 cm below the horseshoe-shaped petiole groove of the lower leaf.
[0026] Step three: Then cut and classify the leaves in turn, use white and black bags to classify the tobacco leaves in different parts, take them out of the field, and pack them under the rainproof shed according to their classification. The stacking height should not exceed 60 cm and they should be left open for 24 hours.
[0027] As a preferred embodiment, in the tobacco loading stage, it can reduce the breakage of tobacco leaves in the tobacco hanging stage, and reduce the damage to the cigarette clips; in the tobacco baking stage, it can realize the transportation of appropriate amount of water from the stems to the leaves of the baking tobacco to meet the needs of the leaf life metabolism, and can avoid the traditional half-cut stem harvesting that causes part of the tobacco leaves to be scraped of dust due to excessive water, and can also avoid the single leaf with small stem The less water supply and the additional increase in labor costs. After use, it can improve the baking quality of tobacco leaves and reduce the consumption of baking fuel.
[0028] In summary, the present invention mainly has the following beneficial effects:
[0029] 1. The present invention is provided with a picking mechanism slidingly arranged on one side of the vehicle body. After the picking mechanism completes picking of its tobacco leaves, it will slide downward under the action of the electric slide. When the electric slide moves to the first guide post, the second guide post squeezes the first guide post to one side under the action of the elastic component. At this time, the second tooth block on the second guide post drives the adjusting gear to rotate. Through the cooperation between the transmission components, the picking mechanism is rotated and adjusted as a whole. At this time, the clamping plate can be rotated to the bottom, which is convenient for the subsequent direct placement of the picked tobacco leaves in the collection bin, reducing the collection burden of tobacco farmers during the picking process and further improving the overall picking efficiency of the device.
[0030] 2. The present invention elastically provides a column on one side of the first guide column, and provides a first tooth block on one side of the column. When the first guide column is squeezed by the second guide column, the column will drive the first tooth block to move downward, thereby driving the fixed gear to rotate, thereby releasing the sealing work of the baffle door on the collecting bin, and realizing that the cover plate at the collecting bin is automatically opened after picking is completed. After subsequent resetting, the cover plate re-seals the collecting bin. In this process, external dust and water vapor are effectively prevented from entering the collecting bin, further improving the subsequent overall collection quality of tobacco leaves.

[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0044] The following describes an embodiment of the present invention based on its overall structure.
[0045] First embodiment:
[0046] See also Figure 1-10The figure shows an upper tobacco leaf segmented stem picking device and a picking method thereof, comprising a vehicle body 1, a picking mechanism 2, a transmission assembly, a reset mechanism and a collection mechanism. Since an array of universal wheels are symmetrically arranged at the bottom of the vehicle body 1, the vehicle body 1 is convenient for stable sliding in the tobacco leaves under the action of the universal wheels, thereby improving the overall picking efficiency of the device, and a detection probe is arranged at the front end of the vehicle body 1, through which the overall height of the tobacco leaves can be detected, and at the same time, the picking mechanism 2 is moved to a specified height through the cooperation of the electric slider 17 and the electric slide 3. In this process, the clamping plate 202 in the picking mechanism 2 clamps the upper part of the tobacco leaf with shearing, and the tobacco leaves are sheared by the electric scissors 203. At this time, the clamping plate 202 prevents the tobacco leaves from falling;
[0047] The picking mechanism 2 is slidably arranged on one side of the vehicle body 1, and an electric slider 17 that slides with the vehicle body 1 is connected to one end of the picking mechanism 2. A second guide post 16 is elastically arranged at one end of the electric slider 17. Under normal conditions, the elastic component of the second guide post 16 located in the electric slider 17 is in a compressed state. When the electric slider 17 slides to the first guide post 8 through the electric slide groove 3, the second guide post 16 squeezes the first guide post 8 under the action of the elastic component. Since an array of second tooth blocks 18 are arranged on the second guide post 16, the second tooth blocks 18 will drive the adjustment during the sliding process of the second guide post 16. The segment gear 12 rotates, and the worm 14 rotates in cooperation with the transmission component, and the picking mechanism 2 is rotated in an angle through the cooperation of the worm 14 and the worm wheel 15. At this time, the clamping plate 202 is at the bottom of the picking mechanism 2, and the electric scissors 203 are at the top of the picking mechanism 2, which is convenient for the subsequent discharge of the tobacco leaves on the clamping plate 202 into the collection bin 7. In addition, a baffle door 6 is provided at one side of the collection bin 7 at the front end of the vehicle body 1, and the collection bin 7 is conveniently shielded by the baffle door 6. The subsequent staff can open the baffle door 6 to take out the tobacco leaves collected inside.
[0048] The first guide post 8 that cooperates with the second guide post 16 is elastically arranged in the car body 1, and a column 9 is elastically arranged on one side of the first guide post 8. In the process of the second guide post 16 resetting and squeezing the first guide post 8, the first guide post 8 will cause the column 9 on one side to slide downward. Since a first tooth block 10 is arranged on one side of the column 9, and a fixed gear 11 is rotatably arranged on one side thereof, the fixed gear 11 will rotate under the action of the first tooth block 10 during the downward sliding process of the column 9. A collecting bin 7 is opened in the car body 1, and a cover plate 5 that cooperates with the fixed gear 11 is rotatably arranged on the top of the collecting bin 7. When the electric slider 17 slides downward through the electric slide 3, the fixed gear 11 will drive the cover plate 5 to rotate, thereby making the top of the collecting bin 7 in an open state. At this time, the tobacco leaves on the clamping plate 202 can directly fall into the collecting bin 7. After the subsequent resetting, the cover plate 5 will reseal the collecting bin. In this process, external dust and water vapor are effectively prevented from entering the collecting bin 7, further improving the overall collection quality of subsequent tobacco leaves.
[0049] In the above embodiments, please refer to Figure 3 , Figure 4 and Fig. 9 , an array of second tooth blocks 18 meshing with the adjusting gear 12 is arranged on the top of the second guide column 16, and an elastic component is connected to one end of the second guide column 16. When the second guide column 16 moves to the first guide column 8, the first guide column 8 is squeezed to make the second guide column 16 drive the second tooth block 18 on the top to slide, thereby driving the adjusting gear 12 to rotate, and the setting of the elastic component facilitates the second guide column 16 to slide stably laterally, and one end of the adjusting gear 12 is connected to the transmission mechanism 13, and the other end of the transmission mechanism 13 is connected to the worm 14, and the bottom of the worm 14 is meshed with the worm wheel 15. When the adjusting gear 12 rotates, the transmission mechanism 13 is driven to rotate, so that the worm 14 at the other end of the transmission mechanism 13 rotates. Since the worm 14 and the worm wheel 15 are meshed with each other, the worm wheel 15 will also rotate with it when the worm 14 rotates.
[0050] In the above embodiments, please refer to Figure 5 The picking mechanism 2 includes a controller 201, a clamping plate 202 and an electric scissors 203. The electric scissors 203 are arranged on one side of the controller 201, and the clamping plate 202 is connected to the top of the electric scissors 203. When the picking mechanism 2 is moved to a specified height by the electric slider 17, the controller 201 controls the clamping plate 202 to clamp the upper part of the tobacco leaves, and then the tobacco leaves are cut by the electric scissors 203. At this time, the clamping plate 202 can clamp and limit the cut tobacco leaves, effectively preventing the tobacco leaves from falling, and further reducing the burden of collecting subsequent tobacco leaves.
[0051] Second embodiment:
[0052] See also Figure 4 The upper tobacco leaf segmented stem picking device and picking method shown in the figure have an overall structure similar to that of Example 1, wherein the transmission mechanism 13 includes a driving disk, a transmission belt and a driven disk, one end of the adjusting gear 12 is connected to the driving disk, and one end of the driven disk is connected to the worm 14, when the adjusting gear 12 rotates under the action of the second guide column 16, it will drive the driving disk at one end to rotate, and the driven disk will follow the rotation under the action of the transmission belt, thereby realizing the following rotation of the worm 14, since the diameter of the driving disk in the transmission mechanism 13 is larger than the diameter of the driven disk, when the adjusting gear 12 rotates by a certain angle during the rotation process, the worm 14 will rotate several times the number of circles, thereby ensuring that the subsequent picking mechanism 2 can rotate stably.
[0053] The present invention is in specific operation: when in use, the vehicle body 1 is used to move the device as a whole to the specified position, and then the picking mechanism 2 is moved to the specified height of the tobacco leaves through the cooperation of the electric slide 3 and the electric slider 17. The tobacco leaves are picked under the action of the picking mechanism 2, and at the same time, the clamping plate 202 clamps the picked tobacco leaves, and the electric slide 3 drives the electric slider 17 to move downward. When the electric slider 17 moves to the first guide post 8, the second guide post 16 squeezes the first guide post 8 under the action of the elastic component in the electric slide 3. At this time, the second guide post 16 slides outward and drives the adjusting gear 12 to rotate under the action of the second tooth block 18. With the cooperation of the transmission component, the overall angle of the picking mechanism 2 is adjusted, and the clamping plate 202 drives the picked tobacco leaves to rotate to the bottom, and then puts them into the collection bin 7 in the vehicle body 1.
[0054] When the first guide column 8 is squeezed by the second guide column 16, the column 9 will slide downward under the action of the first guide column 8, and the fixed gear 11 will rotate accordingly under the action of the first tooth block 10 on one side of the column 9. During this process, the cover plate 5 on the top of the collecting bin 7 will rotate ninety degrees, thereby causing the picked tobacco leaves on the clamping plate 202 to fall into the collecting bin 7. During the subsequent resetting process, the second guide column 16 will be squeezed by the electric slide 3 and slide. At this time, the picking mechanism 2 rotates and resets, and the first guide column 8 follows and resets under the action of the elastic component. During this process, the cover plate 5 will re-seal the top of the collecting bin 7, thereby effectively preventing external dust and water vapor from entering the collecting bin 7, further improving the subsequent overall collection quality of tobacco leaves.
[0055] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
