Description

Technical Field

[0001] This utility model relates to the field of sorting device technology, and in particular to a tobacco leaf weighing and sorting device. Background Technology

[0002] Tobacco leaf weighing and sorting refers to the precise classification of harvested tobacco leaves according to their quality, specifications, and other requirements, and the determination of the weight of each batch of tobacco leaves by weighing, so as to facilitate subsequent processing and sales. This ensures that the quality and specifications of the tobacco leaves meet market demands, improves production efficiency, optimizes resource allocation, and protects the income of tobacco farmers. However, many aspects of the existing technology still require manual operation, and staff need to constantly monitor the weight of the tobacco leaves for collection and packaging, which still poses the problem of excessive manpower consumption. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, which require manual operation in many areas and workers need to constantly monitor the weight of tobacco leaves for collection and packaging, resulting in excessive manpower consumption. Therefore, a tobacco leaf weighing and sorting device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tobacco leaf weighing and sorting device includes a stepped table, a motor frame and a support frame. The motor frame and the support frame are both fixedly connected to one side of the upper end of the stepped table. The sorting device also includes a conveying mechanism located on the stepped table. The conveying mechanism is used to convey the sorted tobacco leaves.

[0006] The sorting mechanism, located at the top of the stepped table, is used to screen tobacco leaves.

[0007] Preferably, the conveying mechanism includes: two connecting shafts, two rotating sleeves, a transmission belt, a stepper motor, a weight sensing unit, and a storage box;

[0008] Two connecting shafts are symmetrically rotated and connected to one side of the stepped table body. Two rotating sleeves are respectively rotated and fixedly sleeved on the two connecting shafts. The transmission belt is rotated and sleeved on the two rotating sleeves. The output shaft of the stepper motor is fixedly connected to the fixedly sleeved rotating sleeve. The motor frame is fixedly sleeved on the stepper motor. The weight sensing unit is fixedly connected to the support frame and located inside the transmission belt and in contact with the transmission belt. The weight sensing unit is electrically connected to the stepper motor. The transmission belt has multiple grooves, and the storage box is placed in the grooves.

[0009] Furthermore, when the weight detected by the weight sensing unit reaches a certain value, the stepper motor will be activated. The output shaft of the stepper motor drives the rotating sleeve to rotate, which in turn drives the transmission belt to rotate, thereby conveying the storage box and thus conveying the tobacco leaves that have been measured to a fixed weight.

[0010] Preferably, the sorting mechanism includes: a box, a discharge port, a chute, a top box, a compartment, a motor, a rotating rod, a fixed block, a limiting rod, a connecting rod, a pull rod, a U-shaped pull rod, two U-shaped blocks, a U-shaped sliding plate, a sliding hole, a slider, a first screen plate, and a second screen plate;

[0011] The box body is fixedly connected to the stepped table. The discharge port is located on one side of the box body. A chute is located on the inner wall of one side of the box body. A fixing block is fixedly connected to the upper end of the box body. The top box is fixedly fitted onto the upper end of the box body. The output shaft of the motor rotates through the top box and is rotatably connected to one end of a rotating rod inside the compartment. The other end of the rotating rod is rotatably connected to one side of a connecting rod and one end of a pull rod. The two ends of the connecting rod are rotatably connected to one end of a limiting rod and one end of a U-shaped pull rod, respectively. The other end of the limiting rod is rotatably connected to one side of the fixing block. The U-shaped slide plate is slidably connected to the slide groove, and the slide hole is opened at the top of the U-shaped slide plate. The slider slides inside the U-shaped slide plate. Two U-shaped blocks are fixedly connected to the upper ends of the U-shaped slide plate and the slider respectively. The U-shaped end of the U-shaped pull rod is rotatably connected to the inner walls of the two sides of the U-shaped block on the U-shaped slide plate. The other end of the pull rod slides through the inner walls of the two sides of the U-shaped pull rod and the slide hole and is rotatably connected to the inner walls of the two sides of the U-shaped block on the slider. The No. 1 sieve plate and the No. 2 sieve plate are fixedly connected to one side of the U-shaped slide plate and the slider respectively and slide inside the box.

[0012] Furthermore, by starting the motor, the output shaft of the motor drives one end of the rotating rod to rotate, which in turn drives the connecting rod to swing around one end of the rotating rod and rotate around the other end of the rotating rod. At the same time, the limiting rod will pull and limit the connecting rod. The two ends of the limiting rod rotate around one end of the connecting rod and the fixed block, respectively. Using the rotational force and swinging force of the connecting rod, the U-shaped pull rod and the pull rod can be reciprocated and pulled, thereby reciprocating and pulling the U-shaped slide plate and the slider. At the same time, the two ends of the pull rod rotate around one side of the connecting rod and the U-shaped block on the slider, respectively. The two ends of the U-shaped pull rod rotate around the other end of the connecting rod and the U-shaped block on the U-shaped slide plate, respectively. This allows the No. 1 screen plate and the No. 2 screen plate to be reciprocated and pulled, thereby screening the tobacco leaves on the screen plates.

[0013] Preferably, the box body is provided with a dust inlet, and a dustproof shell is fixedly connected to one side of the box body, which is fitted on the outside of the discharge port and the dust inlet. An air pump is bolted to one side of the dustproof shell, and an air supply pipe is fixedly connected to the air outlet of the air pump. One end of the air supply pipe is fixedly connected through the dustproof shell and is fixedly connected to an air blowing pipe.

[0014] Furthermore, by starting the air pump before the tobacco leaves fall from the discharge port after screening, the gas generated by the air pump is blown out through the air pipe via the air delivery pipe. This allows the dust in the tobacco leaves to be blown into the chamber through the dust inlet as the tobacco leaves fall, thus preventing a large amount of dust from spreading and affecting the health of the staff.

[0015] Preferably, a storage box slides through one side of the stepped table body, and the storage box is connected to the bottom of the box body.

[0016] Furthermore, when dust from the tobacco leaves enters the box, it falls into the storage box, thus allowing for dust collection.

[0017] Preferably, a flip door is rotatably connected to the opening of the top box, a handle is fixedly connected to the flip door, and two pipe clamps are fixedly connected to one side of the flip door. Two fixing posts are fixedly connected to one side of the opening of the top box, and the fixing posts are engaged with the pipe clamps.

[0018] Furthermore, by pulling the handle, the pipe clamp disengages from the fixed post, which allows the flip door to open, thus enabling the tobacco leaves to be placed from the opening of the top box.

[0019] Beneficial effects:

[0020] 1. When the weight detected by the weight sensing unit reaches a certain value, the stepper motor will be started. The output shaft of the stepper motor drives the rotating sleeve to rotate, which in turn drives the transmission belt to rotate, thereby conveying the storage box and thus conveying the tobacco leaves with a fixed weight.

[0021] 2. By starting the motor, the output shaft of the motor drives one end of the rotating rod to rotate, which in turn drives the connecting rod to swing around one end of the rotating rod and rotate around the other end of the rotating rod. At the same time, the limiting rod will pull and limit the connecting rod. The two ends of the limiting rod rotate around one end of the connecting rod and the fixed block, respectively. Using the rotational force and swinging force of the connecting rod, the U-shaped pull rod and the pull rod can be reciprocated and pulled, thereby reciprocating and pulling the U-shaped slide plate and the slider. At the same time, the two ends of the pull rod rotate around one side of the connecting rod and the U-shaped block on the slider, respectively. The two ends of the U-shaped pull rod rotate around the other end of the connecting rod and the U-shaped block on the U-shaped slide plate, respectively. This allows the No. 1 screen plate and the No. 2 screen plate to be reciprocated and pulled, thereby screening the tobacco leaves on the screen plates.

[0022] In this invention, the cooperation between the conveying mechanism and the sorting mechanism can effectively avoid excessive manpower consumption and prevent staff from expending a lot of energy on constantly monitoring the tobacco leaves. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1-7 A tobacco leaf weighing and sorting device includes a stepped table 1, a motor frame 30 and a support frame 31. The motor frame 30 and the support frame 31 are both fixedly connected to one side of the upper end of the stepped table 1. The sorting device also includes a conveying mechanism located on the stepped table 1. The conveying mechanism is used to convey the sorted tobacco leaves.

[0033] The sorting mechanism, located at the top of the stepped table 1, is used to screen tobacco leaves.

[0034] In this utility model, the conveying mechanism includes: two connecting shafts 26, two rotating sleeves 27, a transmission belt 28, a stepper motor 29, a weight sensing unit 32, and a storage box 33;

[0035] like Figure 2 As shown, two connecting shafts 26 are symmetrically rotatably connected to one side of the stepped table body 1. Two rotating sleeves 27 are respectively rotatably and fixedly sleeved on the two connecting shafts 26. The transmission belt 28 is rotatably sleeved on the two rotating sleeves 27. The output shaft of the stepper motor 29 is fixedly connected to the fixedly sleeved rotating sleeve 27. The motor frame 30 is fixedly sleeved on the stepper motor 29. The weight sensing unit 32 is fixedly connected to the support frame 31 and located inside the transmission belt 28, in contact with the transmission belt 28. The weight sensing unit 32 is electrically connected to the stepper motor 29. The transmission belt 28 has multiple grooves, and the storage box 33 is placed in the grooves. When the weight detected by the weight sensing unit 32 reaches a certain value, the stepper motor 29 will be started. The output shaft of the stepper motor 29 drives the rotating sleeves 27 to rotate, thereby driving the transmission belt 28 to rotate, and thus conveying the storage box 33. This allows the tobacco leaves with a fixed weight to be conveyed.

[0036] In this utility model, the sorting mechanism includes: a box body 3, a discharge port 4, a chute 6, a top box 7, a compartment 8, a motor 9, a rotating rod 10, a fixing block 11, a limiting rod 12, a connecting rod 13, a pull rod 14, a U-shaped pull rod 15, two U-shaped blocks 16, a U-shaped sliding plate 17, a sliding hole 18, a slider 19, a first sieve plate 20, and a second sieve plate 21;

[0037] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the box body 3 is fixedly connected to the stepped table body 1. The discharge port 4 is opened on one side of the box body 3. The slide 6 is opened on the inner wall of one side of the box body 3. The fixing block 11 is fixedly connected to the upper end of the box body 3. The top box 7 is fixedly sleeved on the upper end of the box body 3. The output shaft of the motor 9 rotates through the top box 7 and is rotatably connected to one end of the rotating rod 10 in the compartment 8. The other end of the rotating rod 10 is rotatably connected to one side of the connecting rod 13 and one end of the pull rod 14. The two ends of the connecting rod 13 are rotatably connected to one end of the limiting rod 12 and one end of the U-shaped pull rod 15, respectively. The other end of the limiting rod 12 is rotatably connected to one side of the fixed block 11. The U-shaped slide plate 17 is slidably connected to the slide groove 6. The slide hole 18 is opened at the top of the U-shaped slide plate 17. The slider 19 slides inside the U-shaped slide plate 17. Two U-shaped blocks 16 are fixedly connected to the upper ends of the U-shaped slide plate 17 and the slider 19, respectively. The U-shaped end of the U-shaped pull rod 15 is rotatably connected to the inner walls of the two sides of the U-shaped block 16 on the U-shaped slide plate 17. The other end of the pull rod 14 slides through the inner walls of the two sides of the U-shaped pull rod 15 and the slide hole 18 and is rotatably connected to the U-shaped block 16 on the slider 19. On the inner walls of both sides, the No. 1 sieve plate 20 and the No. 2 sieve plate 21 are fixedly connected to one side of the U-shaped sliding plate 17 and the slider 19, respectively, and slide within the housing 3. By starting the motor 9, the output shaft of the motor 9 drives one end of the rotating rod 10 to rotate, which in turn drives the connecting rod 13 to swing around one end of the rotating rod 10 and rotate around the other end of the rotating rod 10. At the same time, the limiting rod 12 will pull and limit the connecting rod 13. The two ends of the limiting rod 12 rotate around one end of the connecting rod 13 and the fixing block 11, respectively. The rotational and swinging forces of rod 13 can reciprocate the lifting operations of U-shaped pull rod 15 and pull rod 14, thereby reciprocating the lifting operations of U-shaped slide plate 17 and slider 19. At the same time, the two ends of pull rod 14 rotate about one side of connecting rod 13 and the U-shaped block 16 on slider 19, respectively, and the two ends of U-shaped pull rod 15 rotate about the other end of connecting rod 13 and the U-shaped block 16 on U-shaped slide plate 17, thereby reciprocating the lifting operations of screen plate 20 and screen plate 21, thereby screening the tobacco leaves on the screen plates.

[0038] like Figure 5 and Figure 6 As shown, the housing 3 has a dust inlet 5. A dust cover 22 is fixedly connected to one side of the housing 3, which is fitted over the outside of the discharge port 4 and the dust inlet 5. An air pump 24 is bolted to one side of the dust cover 22. An air supply pipe 25 is fixedly connected to the air outlet of the air pump 24. One end of the air supply pipe 25 passes through the dust cover 22 and is fixedly connected to an air blowing pipe 23. The air pump 24 is started before the tobacco leaves fall from the discharge port 4 after screening. The gas generated by the air pump 24 is blown out from the air blowing pipe 23 through the air supply pipe 25. This can blow the dust in the tobacco leaves into the housing 3 from the dust inlet 5 when the tobacco leaves fall, thus avoiding the spread of a large amount of dust that may affect the health of the staff.

[0039] like Figure 1 As shown, a storage box 2 slides through one side of the stepped table body 1. The storage box 2 is connected to the bottom of the box body 3. When dust from the tobacco leaves enters the box body 3, it falls into the storage box 2, thus collecting the dust.

[0040] like Figure 1 and Figure 7 As shown, a flip door 34 is rotatably connected to the opening of the top box 7. A handle 37 is fixedly connected to the flip door 34, and two pipe clamps 35 are fixedly connected to one side of the flip door 34. Two fixing posts 36 are fixedly connected to one side of the opening of the top box 7. The fixing posts 36 and the pipe clamps 35 are engaged. By pulling the handle 37, the pipe clamps 35 are disengaged from the fixing posts 36, thereby opening the flip door 34, so that tobacco leaves can be put in from the opening of the top box 7.

[0041] It should be noted that the specific models of the electric motor 9, air pump 24, stepper motor 29, and weight sensing unit 32 used can be selected by those skilled in the art. Furthermore, the electric motor 9, air pump 24, stepper motor 29, and weight sensing unit 32 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0042] The working principle of this utility model:

[0043] First, pull handle 37 to disengage pipe clamp 35 from fixed post 36, allowing flip door 34 to open and tobacco leaves to be inserted through opening of top box 7. Then, start motor 9. The output shaft of motor 9 drives one end of rotating rod 10 to rotate, which in turn causes connecting rod 13 to swing about one end of rotating rod 10 while simultaneously rotating about the other end. At the same time, limiting rod 12 pulls and limits connecting rod 13, with its two ends respectively centered on one end of connecting rod 13 and fixed block 11. The rotation of the center, utilizing the rotational and oscillating forces of the connecting rod 13, allows for the reciprocating lifting operation of the U-shaped pull rod 15 and pull rod 14, thereby enabling the reciprocating lifting operation of the U-shaped slide plate 17 and slider 19. Simultaneously, both ends of the pull rod 14 rotate about one side of the connecting rod 13 and the U-shaped block 16 on the slider 19, respectively. Similarly, both ends of the U-shaped pull rod 15 rotate about the other end of the connecting rod 13 and the U-shaped block 16 on the U-shaped slide plate 17, thus enabling the reciprocating lifting operation of the first screen plate 20 and the second screen plate 21. The operation involves pulling the tobacco leaves on the screen plate to screen them. Before the screened tobacco leaves fall from the discharge port 4, the air pump 24 is activated. The air pump 24 generates gas that is blown out through the air pipe 25 and the air blowing pipe 23. This blows the dust from the tobacco leaves into the housing 3 through the dust inlet 5 as the leaves fall, and the dust falls into the storage box 2. This dust collection helps to prevent large-scale dust diffusion from affecting the health of the workers. Qualified tobacco leaves fall into the collection box 33. The weight is detected by the weight sensing unit 32. When a certain value is reached, the stepper motor 29 will be activated. (The weight sensing unit 32 is prior art, cited from patent publication number CN214826779U. It utilizes the actual operating principle and start-up control program in the prior art to control the start-up of the stepper motor 29 through weight.) The output shaft of the stepper motor 29 drives the rotating sleeve 27 to rotate, thereby driving the transmission belt 28 to rotate, which in turn can transport the storage box 33, thereby transporting the tobacco leaves that have been detected to a fixed weight.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
