Description

A film rolling mechanism for tobacco cultivation Technical Field

[0001] This utility model belongs to the field of tobacco planting technology, specifically relating to a film rolling mechanism for tobacco leaf planting. Background Technology

[0002] In my country, the area covered by plastic film mulching for tobacco cultivation accounts for approximately 70% of the total tobacco planting area. Plastic film mulching has become an important technical measure in tobacco cultivation. However, due to the high cost and low acceptance of biodegradable films, ordinary PVC plastic film is mostly used for tobacco planting. Because it is non-biodegradable, leaving it in the field causes serious soil pollution, sometimes hindering seedling root growth, isolating water, and in severe cases, causing seedlings to wither and die. Therefore, when the tobacco leaves reach a certain size, the plastic film needs to be recycled. Current technologies for plastic film recycling suffer from low efficiency, excessive soil contamination on the film, and reduced soil around tobacco roots, which is detrimental to tobacco growth. Therefore, a film-rolling mechanism for tobacco planting is needed to solve these technical problems. Summary of the Invention

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a film-rolling mechanism for tobacco planting, including a traveling trolley; the traveling trolley is equipped with a film-rolling roller, the film-rolling roller is connected to the body of the traveling trolley via a bracket, and the film-rolling roller is connected to and driven.

[0004] One side of the support is hinged to the vehicle body. The support is connected to a soil-shaking assembly. The soil-shaking assembly includes a telescopic rod. One end of the telescopic rod is hinged to the vehicle body, and the other end of the telescopic rod is hinged to the lower surface of the middle part of the support.

[0005] It should be noted that the extension and retraction of the telescopic rod drives the support to rotate back and forth around the junction of the support and the vehicle body, thereby causing the film rolling roller to shake the section of film buried in the soil, shaking off the soil on the film, reducing the load on the film rolling roller, and improving the film rolling effect and efficiency.

[0006] Preferably, the telescopic rod is an electric push rod or a hydraulic cylinder.

[0007] Preferably, the bracket includes two support rods, which are respectively disposed on both sides of the vehicle body. One end of each support rod is hinged to the vehicle body via a hinge shaft. The ends of the two support rods away from the vehicle body are connected by a rotating shaft. A sprocket is fixed at the center of the rotating shaft. A fixing rod is fixed at the middle of the two support rods. A motor is mounted on the fixing rod. A sprocket is connected to the motor and the sprocket is connected to the sprocket via a transmission chain. Film rollers are connected to both ends of the rotating shaft.

[0008] It should be noted that by setting up two film-rolling rollers and using one motor to drive the film-rolling rollers, the film-rolling efficiency is improved. The film-rolling operation can be carried out on the ridges on both sides of the field at the same time, which also improves the energy utilization rate.

[0009] Preferably, each end of the rotating shaft is connected to a telescopic rod two, the fixed end of the telescopic rod two is fixedly connected to the rotating shaft, and the telescopic end of the telescopic rod two passes through the corresponding support rod and is connected to the film roll.

[0010] It should be noted that by extending and retracting the telescopic rod two, the two film-rolling rollers can be adapted to field ridges of different widths, further improving the film-rolling effect.

[0011] Preferably, the film-winding roller is detachably connected to the telescopic end of the telescopic rod two via a connecting flange. This detachable connection facilitates the removal of the rolled-up mulch film and the installation of new film-winding rollers, further improving the efficiency of film winding.

[0012] Preferably, the second telescopic rod is an electric push rod, which is connected to a power source via a conductive slip ring. The conductive slip ring ensures that the electric push rod's extension and retraction are not affected during rotation.

[0013] Preferably, baffles are provided at both ends of the film-winding roller. The baffles prevent the mulch film from falling off the film-winding roller.

[0014] Preferably, the vehicle body is equipped with a soil-gathering assembly, which includes an inclined soil-gathering plate connected to the vehicle body via a connecting rod. The soil-gathering plate allows soil rolled up during the mulch film rolling to be gathered back onto the field ridges and up to the roots of the tobacco seedlings, reducing the impact on the seedlings.

[0015] Preferably, the connecting rod is a telescopic rod three, which is an electric push rod or a hydraulic cylinder. The distance between the soil-collecting plate and the tobacco seedlings can be adjusted by extending and retracting the telescopic rod three, thereby improving the soil-collecting effect.

[0016] Preferably, the soil-collecting plate is connected to a second motor, which is a forward and reverse rotating motor. The output shaft of the forward and reverse rotating motor is connected to the soil-collecting plate, driving the soil-collecting plate to rotate, which can lift the soil-collecting plate off the ground, allowing selection of whether to perform soil-collecting operation as needed.

[0017] Working principle: The traveling trolley moves in the field ridges, and one end of the plastic film is wound around the film-winding roller. Then, as the traveling trolley moves and the film-winding roller rotates, the plastic film is continuously lifted and wound around the film-winding roller. During the above process, the telescopic rod continuously extends and retracts periodically to shake off the soil on the film, reduce the load on the film-winding roller, and improve the film-winding effect and efficiency.

[0018] This utility model also includes other components that enable the normal operation of a film-rolling mechanism for tobacco planting, such as control components for electric push rods, hydraulic rods, traveling trolleys, and motors one and two, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as electric push rods, hydraulic cylinders, conductive slip rings, and traveling trolleys, all employ conventional technologies and equipment in the field.

[0019] The beneficial effects of this utility model are: it can efficiently wind up mulch film, and the soil shaking operation can be carried out during the winding process to reduce the burden on the winding roller and improve the winding efficiency and effect; it is suitable for winding up mulch film with different widths of field ridges and has a wide range of applications.

One end of the telescopic rod 5 is hinged to the vehicle body, and the other end of the telescopic rod 5 is hinged to the lower surface of the middle part of the bracket.

[0030] It should be noted that the extension and retraction of the telescopic rod 5 drives the support to rotate back and forth around the junction of the support and the vehicle body, thereby causing the film rolling roller 3 to shake the film cloth section buried in the soil, shaking off the soil on the film cloth, reducing the load on the film rolling roller 3, and improving the film rolling effect and efficiency.

[0031] The telescopic rod 5 is an electric push rod or a hydraulic cylinder.

[0032] The support frame includes two support rods 2, which are respectively located on both sides of the vehicle body. One end of each support rod 2 is hinged to the vehicle body via a hinge shaft 1. The ends of the two support rods 2 furthest from the vehicle body are connected by a rotating shaft 15.

As the traveling trolley 1 moves and the film-winding roller 3 rotates, the plastic film is continuously lifted and wound around the roller 3. During this process, the telescopic rod 5 periodically extends and retracts, shaking off the soil from the film, reducing the load on the film-winding roller 3, and improving the film-winding effect and efficiency.
