Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a mulch film covering machine. Background Technology
[0002] Mulching technology has the advantages of increasing soil temperature, maintaining soil moisture, reducing weeds, and preventing pests and diseases, and is widely used in agricultural production. Currently, mulching technology has shifted from traditional manual mulching to automated mulching using mulching machines. A mulching machine includes a traction device, film-pressing wheels, and a soil-covering device. The soil-covering device is positioned behind the traction device and passively follows its movement. While moving forward, it uses the power of the traction device to scrape soil onto both sides of the mulch film, completing the mulching process.
[0003] When existing plastic film covering machines are used to cover plastic film on slopes, the soil covering device passively follows the traction device, which generates a lot of resistance. This can easily cause the traction device to slip and make it difficult to move, resulting in poor covering effect or even failure to cover the plastic film. Utility Model Content
[0004] The purpose of this invention is to solve the problem of slippage and walking difficulties of the traction device in the existing technology, which leads to poor covering effect or even failure to cover the mulch film.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic film mulching machine, comprising a hand-held tractor body and a support frame.
[0006] The hand tractor body is equipped with a generator, which is connected to the pulley on the hand tractor body via a belt. The support frame is mounted on the hand tractor body, and the support frame is equipped with a soil covering wheel, a film pressing wheel, and a film mounting base. The support frame is also equipped with a battery, and the soil covering wheel is equipped with a soil shoveling blade.
[0007] The covering wheel is connected to the support frame via a column, and an electric motor is installed on the column. The electric motor is connected to the covering wheel via a bearing.
[0008] Beneficial effects: Because the covering wheel is powered, it forms a four-wheel drive system with the drive wheels of the walking tractor, thus avoiding slippage of the traction device and difficulty in movement during the mulching process, a problem common in traditional mulching machines. It is suitable for various complex terrains, especially for mulching on slopes. Furthermore, the addition of a soil-shoveling blade on the covering wheel improves the mulching effect.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0017] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0018] Reference Figure 1-6 A plastic film mulching machine includes a walking tractor body 1 and a support frame 2. A generator 9 is mounted on the walking tractor body 1, and the generator 9 is connected to a pulley 8 on the walking tractor body 1 via a belt. In this embodiment, the generator 9 is an AC generator with a voltage of 14V and a power of 2200W.
[0019] The support frame 2 is mounted on the body 1 of the hand-held tractor. A soil-covering wheel 3, a film-pressing wheel 4, and a film mounting base 6 are mounted on the support frame 2. A battery 5 is also mounted on the support frame 2. Soil-shoveling blades 13 are evenly mounted on the soil-covering wheel 3. In this embodiment, the number of soil-shoveling blades 13 is four.
[0020] The covering wheel 3 is symmetrically mounted on both sides of the support frame 2 in a figure-eight shape via the column 12. The column 12 is equipped with a motor 10, which is connected to the covering wheel 3 via a bearing 11, which is a one-way bearing. In this embodiment, the motor 10 is a DC motor with a voltage of 12V, a power of 380W, and a speed of 60 rpm.
[0021] The contact points between the soil covering wheel 3 and the drive wheel 7 and the ground are located on the same horizontal plane. In this embodiment, the diameter of the drive wheel 7 is 60 cm, the diameter of the soil covering wheel 3 is 30 cm, and the height of the pressing wheel 4 from the ground is 5-8 cm.
[0022] Working principle: When the hand-held tractor body 1 is started, the pulley 8 on the hand-held tractor body 1 drives the generator 9 to rotate and generate electricity. The electricity generated by the generator 9 enters the battery 5 through the transmission line, and the electricity in the battery 5 then enters the motor 10 through the transmission line. The motor 10 drives the covering wheel 3 to rotate. The drive wheel 7 and the covering wheel 3 form a four-wheel drive mulching machine, avoiding slippage and difficulty in movement when mulching on complex terrain, especially on slopes. The shovel blade 13, as the covering wheel 3 rotates, scrapes soil and covers it onto the mulch film.
