Description

Technical Field

[0001] This utility model belongs to the field of tobacco processing technology, specifically relating to a mechanical leaf remover for removing flue-cured tobacco leaves from the main stem after harvesting and curing with the stem attached. Background Technology

[0002] During tobacco processing, the leaves with stems need to be dried. After being dried, the leaves with stems are taken out of the drying room and then moderately moistened. Without damaging the leaves, the leaves are manually removed from the main stem using a leaf-picking tool.

[0003] However, after the tobacco leaves have been rehydrated, the stems are quite flexible. Manually cutting the leaves with ordinary scissors is labor-intensive, time-consuming, and physically demanding, resulting in low efficiency due to prolonged manual labor. Using a dedicated electric tobacco leaf trimmer saves labor and time, allows for extended operation, and offers high mechanical efficiency without damaging the leaves, ensuring the leaves remain intact after trimming, thus improving grade acceptance standards and increasing economic benefits.

[0004] The cutter head of conventional mechanical data loggers is mostly exposed. If an operator's hand or other body part accidentally comes into contact with the cutter head, the sharp edge can easily cause cuts, scratches, or even more serious injuries. Furthermore, if the equipment is in operation, accidental collisions during rapid movement of the cutter head could lead to even more serious accidents for the operator. Utility Model Content

[0005] The purpose of this utility model is to provide a mechanical leaf remover for removing tobacco leaves from the main stem after harvesting and curing with the stem attached. It enables operators to perform high-speed cutting of the tobacco stem (stem), while employing multiple protection and safety measures to ensure the safety of the operator and guarantee the safe operation of the cutting process.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A mechanical leaf-picking device for removing tobacco leaves from the main stem after harvesting and curing with the stem, including a control box, wherein the control box is connected to a cutter via a conductive cable, and the cutter is powered by the control box;

[0008] The cutter is equipped with a safety mechanism inside, which is designed to work in conjunction with the operator's hand position. The safety mechanism must be squeezed to operate the cutter, thus preventing accidental operation.

[0009] The cutter includes a mounting housing, a limiting housing, a cutter head, an extrusion seat, a drive shaft, and a drive motor. The interior of one end of the mounting housing is electrically connected to the interior of a control box via a conductive cable. The limiting housing is fixedly mounted on one side of the other end of the mounting housing by bolts. The cutter head is mounted inside the other end of the mounting housing and is positioned between the mounting housing and the limiting housing. The extrusion seat is slidably disposed inside the mounting housing, and one end of the extrusion seat is slidably connected to the upper end of the cutter head. The outer edge of one end of the drive shaft is threadedly connected to the interior of the extrusion seat. The drive motor is fixedly connected to the interior of the mounting housing, and the output end of the drive motor is fixedly connected to the other end of the drive shaft.

[0010] This utility model is further configured such that the interior of the mounting housing and the limiting housing is provided with a cutting groove.

[0011] The present invention is further configured such that: the cutter head includes a fixed base, a fixed blade, a rotating blade, and a linkage base; the fixed base is assembled inside the mounting housing; one end of the fixed blade is fixedly connected to the fixed base; the rotating blade is rotatably connected to the fixed base; the linkage base is fixedly connected to the rotating blade; and the interior of the linkage base is slidably connected to one end of the extrusion seat.

[0012] The present invention is further configured such that: a positioning hole is provided inside the fixed blade, and the positioning hole cooperates with the interior of the mounting housing.

[0013] The present invention is further configured such that a strip-shaped limiting groove is provided inside the linkage seat.

[0014] The present invention is further configured such that: the safety unit includes a finger guard ring, an index finger switch, and a thumb switch; the finger guard ring is fixedly connected to the mounting housing; the index finger switch is fixedly disposed at the lower part of the mounting housing and cooperates with the interior of the finger guard ring; the thumb switch is fixedly disposed at the upper part of the mounting housing; and the control box, the index finger switch, the thumb switch, and the drive motor are connected in series.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This practical mechanical leaf remover, which removes tobacco leaves from the main stem after harvesting and curing with the stem attached, adopts a cutting design.

[0026] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1 to 6 As shown, a mechanical leaf remover that removes tobacco leaves from the main stem after harvesting and curing with the stem includes a control box 1. The control box 1 is connected to a cutter 2 via a conductive cable, and the cutter 2 is powered by the control box 1.

[0028] The cutter 2 has a safety device 3 inside, which is coordinated with the hand position of the operator. When operating the cutter 2, the safety device 3 needs to be squeezed to complete the operation, thereby avoiding accidental operation.

[0029] The cutter 2 includes a mounting housing 201, a limiting housing 202, a cutter head 203, an extrusion seat 204, a drive shaft 205, and a drive motor 206. The interior of one end of the mounting housing 201 is electrically connected to the interior of the control box 1 via a conductive cable. The limiting housing 202 is fixedly mounted on one side of the other end of the mounting housing 201 by bolts. The cutter head 203 is mounted inside the other end of the mounting housing 201 and is located between the mounting housing 201 and the limiting housing 202. The extrusion seat 204 is slidably disposed inside the mounting housing 201, and one end of the extrusion seat 204 is slidably connected to the upper end of the cutter head 203. The outer edge of one end of the drive shaft 205 is threadedly connected to the interior of the extrusion seat 204. The drive motor 206 is fixedly connected to the interior of the mounting housing 201, and the output end of the drive motor 206 is fixedly connected to the other end of the drive shaft 205.

[0030] Specifically, when it is necessary to harvest the target, the operator holds the cutter 2 and aligns it with the target position. Then, the operator applies pressure to the safety part 3 on the cutter 2, so that the power inside the control box 1 supplies power to the drive motor 206 through the wire cable. The power supply to the drive motor 206 can drive the drive shaft 205 to rotate. The rotation of the drive shaft 205 causes the threaded extrusion seat 204 to slide inside the mounting housing 201. The sliding of the extrusion seat 204 can drive the cutter head 203 to rotate and extend inside the mounting housing 201, thereby extruding and cutting the target to be harvested.

[0031] After the cutting is completed, the operator releases the pressure applied to the safety unit 3, causing the power inside the control box 1 to drive the drive motor 206 to rotate in the opposite direction. The output end of the drive motor 206 drives the drive shaft 205 to rotate in the opposite direction, causing the drive shaft 205 to drive the extrusion seat 204 to slide in the opposite direction. This causes the extrusion seat 204 to drive the cutter head 203 to retract into the interior of the mounting housing 201, returning to the initial state.

[0032] The control box 1 has an integrated control module that is responsible for the control, power supply and safety of the cutter 2.

[0033] like Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, the mounting housing 201 and the limiting housing 202 are provided with cutting grooves. The target to be cut is placed inside the cutting groove, and the target is cut by the extension of the blade 203, so as to achieve accurate cutting of the target.

[0034] At the same time, assembling the cutter head 203 between the mounting housing 201 and the limiting housing 202 can prevent the operator from bumping into the cutter head 203, thereby preventing injury to the operator and ensuring the operator's safety.

[0035] like Figure 4 As shown, the cutter head 203 includes a fixed base 2031, a fixed blade 2032, a rotating blade 2033, and a linkage base 2034. The fixed base 2031 is assembled inside the mounting housing 201. One end of the fixed blade 2032 is fixedly connected to the fixed base 2031. The rotating blade 2033 is rotatably connected to the fixed base 2031. The linkage base 2034 is fixedly connected to the rotating blade 2033, and the interior of the linkage base 2034 is slidably connected to one end of the extrusion base 204.

[0036] When the cutter head 203 needs to be maintained or replaced, the limiting housing 202 should be removed first, and then the entire cutter head 203 should be removed to facilitate the removal of the cutter head 203.

[0037] When installing the cutter head 203, the blade 2033 needs to be rotated so that the angle of the linkage seat 2034 can be inserted into the interior of the extrusion seat 204. Then, the fixing seat 2031 and the fixing blade 2032 are installed into the interior of the mounting housing 201, and the linkage seat 2034 is also inserted into the interior of the extrusion seat 204, thus realizing the overall installation of the cutter head 203.

[0038] Then, the limiting housing 202 and the mounting housing 201 are fixed with bolts, and the cutter head 203 is limited between the mounting housing 201 and the limiting housing 202 to prevent the cutter head 203 from falling off, thus realizing the convenient replacement of the cutter head 203.

[0039] like Figure 3 and Figure 4 As shown, the fixed blade 2032 has a positioning hole inside, which cooperates with the inside of the mounting housing 201. The positioning hole of the fixed blade 2032 can provide a precise installation position when changing the blade head 203. At the same time, the positioning hole can also prevent the fixed blade 2032 from shifting after the mounting housing 201 and the limiting housing 202 are fixed by bolts, thus improving the stability of the fixed blade 2032 after installation.

[0040] like Figures 3 to 6 As shown, the linkage seat 2034 has a strip-shaped limiting groove inside. When the extrusion seat 204 moves, it is a straight path. When the extrusion seat 204 pulls the linkage seat 2034, the linkage seat 2034 rotates in an arc. In order to match the two path trajectories, the strip-shaped limiting groove is used as a sliding compensation to prevent the linkage seat 2034 from getting stuck during the process of being pulled by the extrusion seat 204, thus ensuring the linkage between the linkage seat 2034 and the extrusion seat 204.

[0041] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the safety unit 3 includes a finger guard ring 301, an index finger switch 302, and a thumb switch 303. The finger guard ring 301 is fixedly connected to the mounting housing 201. The index finger switch 302 is fixedly installed at the lower part of the mounting housing 201. The index finger switch 302 is in the same position as the operator's index finger when holding the device, and the index finger switch 302 cooperates with the inside of the finger guard ring 301. The finger guard ring 301 protects the index finger switch 302 and prevents it from being triggered incorrectly. The thumb switch 303 is fixedly installed at the upper part of the mounting housing 201. The thumb switch 303 is in the same position as the operator's thumb when holding the device. The control box 1, the index finger switch 302, the thumb switch 303, and the drive motor 206 are connected in series.

[0042] When the operator holds the device, pressure can be applied to the corresponding index finger switch 302 and the thumb-mouth switch 303 through the index finger and the web of the hand as an opening signal to be sent to the control box 1. The control box 1 then controls the drive motor 206 to rotate to perform the cutting.

[0043] Cutting can only be performed when the index finger switch 302 and the tiger's mouth switch 303 are pressed and in the open state, which can avoid the operator's mistaken operation of cutting and further ensure the operator's safety.

[0044] When the operator relaxes their grip, the pressure applied to the index finger and the web of the hand is stopped, and the corresponding index finger switch 302 and web of the hand switch 303 are sent to the control box 1 as a closing signal. The control box 1 then controls the drive motor 206 to rotate to perform the retraction.

[0045] The working principle of this utility is as follows: When it is necessary to harvest the target, the operator holds the cutter 2 and aligns it with the target position. Then, the operator applies pressure to the safety part 3 on the cutter 2, so that the power inside the control box 1 supplies power to the drive motor 206 through the wire cable. The power supply to the drive motor 206 can drive the drive shaft 205 to rotate. The rotation of the drive shaft 205 causes the threaded extrusion seat 204 to slide inside the mounting housing 201. The sliding of the extrusion seat 204 can drive the cutter head 203 to rotate and extend inside the mounting housing 201, thereby extruding and cutting the target to be harvested.

[0046] After the cutting is completed, the operator releases the pressure applied to the safety unit 3, causing the power inside the control box 1 to drive the drive motor 206 to rotate in the opposite direction. The output end of the drive motor 206 drives the drive shaft 205 to rotate in the opposite direction, causing the drive shaft 205 to drive the extrusion seat 204 to slide in the opposite direction. This causes the extrusion seat 204 to drive the cutter head 203 to retract into the interior of the mounting housing 201, returning to the initial state.

[0047] The control box 1 has an integrated control module that is responsible for the control, power supply and safety of the cutter 2.

[0048] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
