Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, and specifically relates to a film breaker. Background Technology
[0002] Fully biodegradable mulch film is a novel agricultural input product. Because it degrades into carbon dioxide and water in the soil, it does not need to be recycled from farmland after use. This provides a highly beneficial way to reduce white pollution and promote soil ecological security. Due to the non-recyclable nature of fully biodegradable mulch film, new demands have arisen in specific application scenarios. It is designed to address the need to break the mulch film during the high temperatures of summer to improve soil permeability and reduce soil temperature. Simultaneously, the film-breaking device largely maintains the mulch film's coverage of the soil surface, which can suppress weed growth and reduce the splashing of soil-borne diseases caused by rainfall. However, existing film-breaking devices are complex in structure, expensive, and inconvenient to use.
[0003] In view of this, in order to solve the above problems, this utility model proposes a biodegradable mulch film breaker with a simple structure and convenient use. Summary of the Invention
[0004] This utility model provides a plastic film breaker that is lightweight, simple in structure, easy to use, and inexpensive. The specific solution is as follows:
[0005] A film breaker includes an installation shaft and a traveling wheel sleeved in the middle of the installation shaft. A push rod that can push the traveling wheel forward is connected to the installation shaft. A handrail is horizontally connected to one end of the push rod away from the installation shaft. Film breaker blades are vertically downward on the installation shafts at both ends of the traveling wheel.
[0006] Furthermore, the push rod has a Y-shaped structure, wherein the two free ends on the open side are detachably connected to both ends of the mounting shaft, and the other end is fixedly connected to the handrail.
[0007] Furthermore, each end of the mounting shaft is fitted with a loose sleeve, the two membrane-breaking knives are connected to the two loose sleeves respectively, and compression springs are connected between the two membrane-breaking knives and the two rods on the opening side of the push rod respectively.
[0008] Furthermore, the two membrane-breaking blades and the push rod are set at an acute angle.
[0009] Furthermore, both the push rod and the handrail are hollow structures and connected at the joint. A winch is rotatably connected to both ends of the handrail. A knob connected to the winch is provided at one end of the handrail. Traction ropes are connected to the two membrane-breaking knives respectively, and the two traction ropes pass through the push rod and are connected to the winch.
[0010] The beneficial effects of this utility model are:
[0011] This utility model discloses a film breaker, which consists of an installation shaft, film-breaking blades at both ends of the installation shaft, a traveling wheel in the middle of the installation shaft, and a push rod that can push the traveling wheel forward. When biodegradable film needs to be broken, the traveling wheel is placed in the trench between two unit rows, so that the film-breaking blades at both ends of the installation shaft are placed on the film of the two unit rows respectively, and the push rod is pushed to make the traveling wheel roll forward, thereby achieving the purpose of breaking the biodegradable film. The film breaker has a simple and reasonable structural design, is lightweight, easy to use and operate, and has low manufacturing cost, making it highly practical. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] See Figs. 1-2 A film breaker includes an installation shaft 1 and a traveling wheel 2 sleeved in the middle of the installation shaft 1. A push rod 3 is connected to the installation shaft 1 to push the traveling wheel 2 forward. A handrail 4 is horizontally connected to one end of the push rod 3 away from the installation shaft 1. Film breaker blades 5 are vertically downward on the installation shaft 1 at both ends of the traveling wheel 2, and the two film breaker blades 5 are symmetrically arranged on the installation shaft 1.
[0017] The push rod 3 has a Y-shaped structure, with its two free ends on the open side being detachably connected to both ends of the mounting shaft 1, and its other end being fixedly connected to the handrail 4. The Y-shaped structure design helps the push rod 3 maintain stability when pushed.
[0018] The mounting shaft 1 is fitted with two loose sleeves 6 at both ends. The two film-breaking knives 5 are connected to the two loose sleeves 6 respectively, so that the film-breaking knives 6 can rotate along the mounting shaft 1 in the front and back direction. The two film-breaking knives 5 are connected to the two rods on the open side of the push rod 3 respectively. The compression springs 7 can provide the film-breaking knives 5 with a certain rebound force during the film-breaking process to reduce the travel resistance of the film-breaking knives 5, and can also effectively extend the service life of the film-breaking knives 5.
[0019] The two membrane-breaking blades 5 are set at an acute angle to the push rod 3, which makes it easier to break the membrane when the push rod 3 is pushed through the membrane-breaking blades 5.
[0020] Both the push rod 3 and the handrail 4 are hollow structures and connected at the joint. A winch is rotatably connected to both ends of the handrail 4. A knob 8 connected to the winch is provided at one end of the handrail 4. Two film-breaking blades 5 are respectively connected to traction ropes 9, and the two traction ropes 9 pass through the push rod 3 and are connected to the winch. The design of the knob 8 and the traction ropes 9 makes it easy to adjust the angle between the film-breaking blades 5 and the push rod 3 at any time to accommodate operators of different heights and avoid the film-breaking blades 5 from penetrating too much into the soil when breaking the film. When adjusting, simply rotate the knob 8, and the winch connected to it will rotate, driving the traction ropes 9 to pull the film-breaking blades 5.
[0021] The working principle of this utility model:
[0022] First, place the traveling wheel 2 of this film breaker in the trench between two unit ridges, so that the two film-breaking blades 5 on both sides of the traveling wheel 2 are respectively located on the biodegradable film of the two unit ridges and placed inside the buried film. Then push the handle 4 forward to make the two film-breaking blades 5 cut the film. Repeat the above operation to break the film of other ridges. This film breaker has a simple structure design, is easy to operate, and has strong practicality.
