A tobacco field film removal device

Abstract

This utility model relates to the field of tobacco seedling cultivation technology, specifically to a tobacco field film-removing device, comprising: a frame, a blade assembly mechanism, a film-removing mechanism, and a controller. The controller is fixedly installed at the center of the top surface of the frame, and the film-removing mechanism is slidably connected to the bottom surfaces of both sides of the frame. The blade assembly mechanism is fixedly installed on the top surface of the film-removing mechanism, and the controller controls the operation of the blade assembly mechanism and the film-removing mechanism. The blade assembly mechanism cuts open the film, and simultaneously, at both sides of the film, the film-removing rod pushes upward, causing the soil pressing on the film to separate from the film. At the same time, friction gears are installed on the film-removing rods, which drive the film to move horizontally, thereby separating the cut film from the ridges. This improves the efficiency of film removal and reduces the labor intensity of the operator.

Description

Technical Field

[0001] This utility model relates to the field of tobacco seedling cultivation technology, specifically to a tobacco field film removal device. Background Technology

[0002] Under-film transplanting of flue-cured tobacco seedlings refers to transplanting seedlings with 3 to 5 leaves and 1 bud. During transplanting, watering, fertilization, and film covering are all completed in one process, allowing the seedlings to grow under the film with warmth and moisture for a period before opening the holes for normal management. This drought-resistant and water-saving cultivation method is widely used in Yunnan due to its significant water-saving effect and high seedling survival rate. After the seedlings grow, the film needs to be removed. Traditional methods require squatting or bending over, which is labor-intensive. To allow standing work, a tool using a long pole with a fixed knife was developed to cut the film. However, the operator still needs to lift the pole and knife, bearing their weight, further increasing the labor intensity. Additionally, the film needs to be secured with soil, making conventional knife-cutting techniques ineffective at removing it.

[0003] In view of this, there is an urgent need to design a tobacco field film-removing device that uses a blade mechanism to cut open the film, while simultaneously using a film-removing rod on both sides to push the soil pressing on the film away from it. Furthermore, friction gears are installed on the film-removing rods, which drive the film horizontally, thereby separating the cut film from the ridges. This improves the efficiency of film removal and reduces the labor intensity of the operator. Utility Model Content

[0019] Working principle:

[0020] First, a frame 1 is provided, which consists of a frame body 11 and rollers 12. Rollers 12 are installed on the bottom surfaces of both sides of the frame body 11, and the rollers 12 can move the frame body 11 on the road surface.

[0021] The frame 1 has movable sleeves 31 installed on both sides, which can slide vertically along both sides of the frame 1. A telescopic cylinder 32 is installed on the top surface of the movable sleeve 31, and the driving end of the telescopic cylinder 32 is fixedly connected to the movable sleeve 31. The telescopic cylinder 32 can drive the movable sleeve 31 to rise and fall vertically.

[0022] The film-removing rod 33 is rotatably mounted on the side wall of the movable sleeve 31.

[0023] When the operator uses the device, the film-removing mechanism 3 is first inserted into the film. The controller 4 then controls the film-removing rod 33 to rise and move the frame 1. The film-removing rod 33 then separates the film from the soil. At the same time, the rotation of the friction gear 35 moves the film, thereby separating the film from the soil ridge.

A blade assembly 2 cuts open the film, while simultaneously, film-removing rods 33 push upwards from both sides of the film, separating the soil pressing on it. Friction gears 35 are mounted on the film-removing rods 33, which drive the film horizontally, thus separating the cut film from the ridges. This improves the efficiency of film removal and reduces the operator's workload.
