Description
Technical Field
[0001] The utility model relates to the technical field of tobacco planting, in particular to a device for integrally harvesting and transporting six leaves on a tobacco plant. Background Art
[0002] The top six leaves of a tobacco plant refer to the top six leaves remaining after the middle leaves are harvested. The overall harvesting of the top six leaves can ensure the consistency of maturity of the top leaves, and the overall harvesting method is to cut and harvest together with part of the stems, and at the same time, the stems are braided into poles and sent to the drying room for baking. Compared with harvesting the top leaves in batches, the overall harvesting and baking method of the top six leaves can effectively improve the coordination of the internal chemical composition of the tobacco leaves, thereby meeting the raw material requirements of high-end cigarettes. However, in the prior art, there is the following problem when cutting and harvesting the top six leaves, that is, because the six leaves are integrated with the stems, they cannot be stacked on the basis of fully utilizing the space, and random stacking and stacking will cause some leaves to be pierced by the stems. Utility Model Content
[0003] The purpose of the utility model is to provide a device for harvesting and transporting the six leaves on a tobacco plant as a whole. The utility model has a simple structure and can effectively gather and shape the six leaves that have been cut and harvested, optimize their stacking method in the space of a transport trolley, and improve the harvesting and transport efficiency and effect.
[0004] To achieve the above object, the present invention provides the following technical solutions:
[0005] A device for harvesting and transporting six leaves from a tobacco plant, comprising a crawler vehicle with a storage frame on the top, a shaping mechanism for shaping tobacco leaves installed on the top of the width side wall of the storage frame, the shaping mechanism comprising a hollow ring fixedly connected to the storage frame through a support rod at the bottom, and the axial direction of the hollow ring is arranged parallel to the length direction of the storage frame;
[0006] The inner ring surface of the hollow ring is provided with a plurality of ventilation holes at equal intervals in the circumferential direction, and the hollow portion of the hollow ring is connected with the exhaust pipe of the air pump, and the air pump is fixed on the side wall of one end of the storage frame facing the forward direction.
[0007] Preferably, one end of the hollow ring facing away from the forward direction of the storage frame is smoothly connected to a reducer with a decreasing inner diameter.
[0008] Preferably, two groups of clamping plates for limiting the film roll are respectively arranged at two ends of the top surface of the hollow ring along the axial direction.
[0009] Preferably, the same group of card plates on the side away from the forward direction of the storage frame have a film cutting knife with a cutting edge facing downwards between their tops.
[0010] Preferably, the outer wall of the hollow circular ring is provided with limiting components symmetrically relative to the axis, and the two limiting components are used to limit the two ends of the film roll in the length direction.
[0011] Preferably, the limit assembly includes a limit plate with an ear plate at the bottom and a pin fixed to the outer wall of the hollow ring. The limit plate is rotatably connected to both ends of the pin through the ear plate, and a torsion spring is sleeved on the pin shaft between the ear plates. One end of the torsion spring is against the outer wall of the hollow ring below the pin, and the other end is against the side wall of the limit plate away from the other limit plate.
[0012] The working process of this utility model is as follows:
[0013] First, put the film roll between the clamping plates, and at the same time, the two limit plates are pressed against the axial ends of the film roll under the elastic force of the torsion spring, and the free end of the film is taken out from the gap between the film cutting knife and the outer wall of the hollow ring.
[0014] The upper six leaves after being cut are passed through the hollow ring with the stem as the front end, and then the air pump is turned on. An airflow with a certain pressure blows toward the tobacco leaves from the ventilation holes of the hollow ring and makes the six leaves close together. As the stem passes through the reducing tube, the upper six leaves basically form a cylindrical structure with the stem as the tip and the leaves close to each other. The overall closing process of the upper six leaves is evenly stressed and relatively gentle, which prevents the phenomenon of leaf breakage caused by artificial leaf closing.
[0015] Then stretch the film and wrap it around the outer wall of the tobacco leaves to keep the upper six leaves in a cylindrical state, preventing the upper six leaves from opening relative to the stems again. Then use a film cutting knife to cut the film and tear it off, then remove the upper six leaves from the hollow ring and place them horizontally in the storage frame. The upper six leaves stacked in sequence in the storage frame have the same stem orientation so there will be no puncture. At the same time, the space inside the cylinder can be used to deform and compensate for the gravity of the overlapping, preventing the leaves from being squeezed and damaged.
[0016] The rolling of the film roll itself can realize the continuous supply of film. At the same time, the restriction of the clamping plate can prevent the film roll from moving axially along the hollow ring, and the restriction of the limit plate can prevent the film roll from moving radially along the hollow ring.
[0017] It should be noted that the air pump and the tracked vehicle are powered by lithium batteries, lead-acid batteries, etc. The switch positions of the air pump and the motor controlling the tracked vehicle can be designed according to market needs, such as being set on the outer wall of the hollow ring or the storage frame.
[0018] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure, can effectively gather and shape the upper six leaves that have been cut, optimize their stacking method in the space of the transfer cart, prevent the upper six leaves from being penetrated by leaves and squeezed, and greatly improve the harvesting and transportation efficiency and effect.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] like Figure 1-3 As shown, a device for harvesting and transporting six leaves on a tobacco plant as a whole comprises a crawler vehicle 1 with a storage frame 11 on the top and a shaping mechanism arranged at the top of the width side wall of the storage frame 11, wherein the shaping mechanism comprises a hollow ring 3 fixedly connected to the storage frame 11 through a support rod 2 at the bottom, the axial direction of the hollow ring 3 is arranged parallel to the length direction of the storage frame 11, and the end of the hollow ring 3 facing away from the forward direction of the storage frame is smoothly transitioned and connected to a reducer 31 with a decreasing inner diameter;
[0024] Two groups of clamping plates 32 for limiting the film roll 4 are respectively arranged at both ends of the top surface of the hollow ring 3 in the axial direction. The same group of clamping plates 32 on the side away from the forward direction of the storage frame 11 has a film cutting knife 33 with a downwardly facing edge between its tops.
[0025] The outer wall of the hollow ring 3 is symmetrically provided with a limit assembly relative to the axis, and the limit assembly includes a limit plate 35 with an ear plate 34 at the bottom and a pin 36 fixed to the outer wall of the hollow ring 3. The limit plate 35 is rotatably connected with both ends of the pin 36 through the ear plate 34, and a torsion spring 37 is sleeved on the shaft of the pin 36 between the ear plates 34. One end of the torsion spring 37 is against the outer wall of the hollow ring below the pin, and the other end is against the side wall of the limit plate away from the other limit plate.
[0026] The inner surface of the hollow ring 3 is provided with a plurality of ventilation holes 38 at equal intervals in the circumferential direction, and the hollow portion of the hollow ring 3 is connected to the exhaust pipe 51 of the air pump 5, and the air pump 5 is fixed on the side wall of one end of the storage frame 11 facing the forward direction.
[0027] The working process of this utility model is as follows:
[0028] First, the film roll 4 is placed between the clamping plates 32, and at the same time, the two limit plates 35 are pressed against the axial ends of the film roll 4 under the elastic force of the torsion spring 37, and the free end of the film is taken out from the gap between the film cutting knife 33 and the outer wall of the hollow ring 3.
[0029] The upper six leaves after cutting are passed through the hollow ring 3 with the stem as the front end, and then the air pump 5 is turned on. An airflow with a certain pressure is blown toward the tobacco leaves from the ventilation hole 38 of the hollow ring 3 and the six leaves are brought together. As the stem passes through the reducer 31, the upper six leaves basically form a cylindrical structure with the stem as the tip and the leaves close to each other. The overall gathering process of the upper six leaves is uniformly and gently stressed, which prevents the phenomenon of leaf breakage caused by manual gathering (the tobacco leaves of the upper six leaves are relatively large in volume and 25-35CM in length).
[0030] Then the film is stretched and wrapped around the outer wall of the tobacco leaf to keep the upper six leaves in a cylindrical state, preventing the upper six leaves from opening relative to the stems again. Then the film is cut with a film cutting knife 33 and then torn off, and the upper six leaves are withdrawn from the hollow ring 3 and can be placed horizontally in the storage frame 11. The upper six leaves stacked in sequence in the storage frame 11 have the same stem orientation so that no puncture occurs. At the same time, the space inside the cylindrical shape can be used to deform and compensate for the gravity of the overlapping, preventing the leaves from being squeezed and damaged.
[0031] The rolling of the film roll 4 itself can realize the continuous supply of film. At the same time, the restriction of the clamping plate 32 can prevent the film roll 4 from moving axially along the hollow ring, and the restriction of the limit plate 35 can prevent the film roll from moving radially along the hollow ring.
[0032] It should be noted that the air pump and the tracked vehicle are powered by lithium batteries, lead-acid batteries, etc. The switch positions of the air pump and the motor controlling the tracked vehicle can be designed according to market needs, such as being set on the outer wall of the hollow ring or the storage frame.
