Technical Field
[0001] This utility model relates to the field of tobacco planting technology, and more specifically, to a tobacco curing film tearing device. Background Technology
[0002] Flue-cured tobacco is the most widely cultivated type of tobacco in my country and the world. It is the main raw material for the cigarette industry and is also used for pipe tobacco. When tobacco is planted, it needs to be covered with plastic film to keep it moist and warm. After the tobacco seedlings have grown for a period of time, the plastic film needs to be broken and the seedlings removed to allow them to breathe and grow.
[0003] Existing methods for breaking the film on flue-cured tobacco involve manually tearing a slit in the film near the tobacco seedlings. This method requires workers to constantly bend over and manually tear the film, which can cause back injuries to workers over long periods of time, and the efficiency is also low. Therefore, we have proposed a film-tearing device for flue-cured tobacco. Utility Model Content
[0004] To solve the above problems, this utility model provides a tobacco curing film-tearing device, which adopts the following technical solution: A tobacco curing film-tearing device includes a first support rod and a second support rod disposed on one side of the first support rod. The first and second support rods are assembled by a pivot. Both the first and second support rods have film-tearing claws at their ends. The first support rod includes a first main rod disposed on the same side as the film-tearing claw, and a first movable rod disposed on the side of the first main rod away from the same side as the film-tearing claw. The second support rod includes a second main rod disposed on the same side as the film-tearing claw, and a second movable rod disposed on the side of the second main rod away from the same side as the film-tearing claw. The ends of the first and second main rods away from the same side as the film-tearing claw have movable grooves that match the first and second movable rods on the same side. Both the ends of the first and second movable rods away from the same side as the film-tearing claw have handles. Both the first and second main rods are fixed to the same side as the film-tearing claw. The opposite sides of the first and second movable rods are each provided with movable grooves, and each movable groove is provided with a positioning component.
[0005] By adopting the above technical solution, when using the equipment, the grower can place the film-tearing claw at one end of the first and second support rods, and fix the film-tearing claw to the first or second support rod using the fixing component, which facilitates subsequent disassembly and maintenance. The grower drives the first and second support rods to rotate and fit together on the side wall of the rotating shaft by using the handle, and then brings the film-tearing claw into contact with the mulch film. Then, by driving the first and second support rods to move in the opposite direction by using the handle, the two film-tearing claws move in opposite directions, which can tear open the mulch film, allowing the tobacco to be exposed and breathe, which is conducive to subsequent growth. Large-area mulch film removal can be completed in a short time. At the same time, it greatly reduces the labor intensity of farmers, eliminating the hardship of bending over and manually tearing the film. More importantly, its precise operation effectively reduces damage to tobacco plants, lowers the risk of pest and disease transmission during manual operations, ensures healthy growth of tobacco plants, and lays the foundation for a bumper tobacco harvest. The first support rod is assembled from the first main rod and the second moving rod, and the second support rod is assembled from the second main rod and the second moving rod. Positioning components are provided between the first main rod and the second moving rod, and between the second main rod and the second moving rod, which can be used to position the first moving rod and the second moving rod, and facilitate the adjustment of the distance between the first main rod and the second moving rod, and between the second main rod and the second moving rod, thereby adjusting the length of the first support rod and the second support rod. This makes it easier for growers of different heights to use and improves the effectiveness of the equipment.
[0006] Furthermore, each of the two tearing claws has a plug fixedly installed on the side of the handle on the same side. The first main rod and the second main rod have slots that match the plugs on the same side at the ends of the tearing claws on the same side. Each of the first main rod and the second main rod has a mounting frame fixedly installed on the opposite side. Each of the two mounting frames has a fixing block slidably installed inside. Each of the two fixing blocks has a connecting rod fixedly installed on the opposite side. Each of the two connecting rods has a first spring sleeved on its sidewall. The two connecting rods slide through the mounting frame on the same side at the end away from the fixing block on the same side. Each of the two connecting rods has a pull ring fixedly installed on the end away from the fixing block on the same side. Each of the two fixing blocks slides through the slot on the same side at the end away from the connecting rod on the same side. Each of the two plugs has a fixing groove on its sidewall that matches the fixing block on the same side.
[0007] By adopting the above technical solution, the user places the insert block installed on one side of the film-tearing claw into the slot opened on one side of the first main rod and the second main rod. Both the insert block and the fixing block have chamfers on one side. When the insert block moves into the slot on the same side, the insert block pushes the fixing block on the same side to move into the mounting frame on the same side. The fixing block pushes the first spring on the same side to retract. When the insert block and the slot are fully engaged, the fixing block returns to its original position under the elastic force of the first spring on the same side, and the fixing block engages with the fixing groove opened on the side wall of the insert block on the same side, which can play the role of fixing the insert block and achieving the effect of fixing the film-tearing claw. When it is necessary to replace the film-tearing claw, the user pulls the pull ring, the pull ring pulls the connecting rod on the same side, and the connecting rod moves the fixing block with the fixing groove opened on the side wall of the insert block on the same side, so that the fixing block and the fixing groove opened on the side wall of the insert block on the same side are disengaged, making it easy for the user to pull the insert block out of the slot on the same side, which can play the role of disassembling the film-tearing claw.
[0008] Furthermore, a first magnet is embedded on the side of each of the two inserts away from the same-side tearing claw, and a second magnet is fixedly installed on the inner wall of each of the two slots away from the same-side tearing claw.
[0009] By adopting the above technical solution, a first magnet is provided on one side of the insert block and a second magnet is provided in the slot. The attraction force of the first magnet and the second magnet on the same side can further fix the stability of the insert block and the slot engagement, which is conducive to maintaining the stability of the film tearing claw installation.
[0010] Furthermore, both mounting frames have grooves at the top and bottom, and sliders are slidably installed in the grooves. The two sliders on the same side are fixedly connected to the opposite side of the fixed block on the same side.
[0011] By adopting the above technical solution, when the fixed block slides within the mounting frame, the fixed block, along with the slider, slides within the same-side groove. The cooperation between the slider and the groove helps maintain the stability of the fixed block's movement and helps prevent the fixed block from detaching from the same-side mounting frame.
[0012] Furthermore, the positioning assembly includes a positioning rod that is slidably installed in the movable groove. A second spring is fixedly connected between the positioning rod and the inner wall of the opposite side of the movable groove. Multiple positioning holes matching the positioning rod are opened on the opposite sides of the first main rod and the second main rod.
[0013] By adopting the above technical solution, when adjusting the length of the first support rod and the second support rod, the user can press the positioning rod to disengage it from the positioning hole, and then pull the first or second moving rod to move it within the moving groove on the same side. This can adjust the length of the first and second support rods, making it easier for users of different heights to use and improving the equipment's performance. Furthermore, the positioning rod can move under the force of the second spring on the same side, allowing it to engage with the corresponding positioning hole again, thus fixing the first and second moving rods in place.
[0014] Furthermore, screws are fixedly installed on the side walls of both handles, and the first and second moving rods have threaded grooves that match the screws on the same side at the ends near the handles on the same side.
[0015] By adopting the above technical solution, the first moving rod, the second moving rod, and the handle on the same side are all fixed by screws and screw grooves, which facilitates disassembly and assembly by users.
[0016] In summary, this utility model has the following beneficial technical effects: (1) In this utility model, the cooperation of the first support rod, the second support rod, the handle and the film tearing claw makes it easy for the planter to tear the mulch without having to bend over many times, which is conducive to improving the tearing efficiency of the mulch and reducing the workload of the planter. The distance between the first main rod and the first moving rod, the second main rod and the second moving rod can be adjusted, which can adjust the length of the first support rod and the second support rod, making it convenient for planters of different heights to use and improving the use effect of the equipment.
[0017] (2) In this utility model, the first main rod, the second main rod and the same side tearing claw are all assembled by fixing components. The interlocking of the insert block and the slot plays the role of positioning the tearing claw. Then, the fixing slot opened on the side wall of the fixing block and the insert block can be used to fix the tearing claw, and it is convenient to disassemble and assemble the tearing claw later.
