Description

Technical Field

[0001] The utility model relates to a ridge body shaping and film pressing device, belonging to the technical field of film covering on ridge surfaces of tobacco fields. Background Art

[0002] In modern agricultural production, especially in tobacco planting, the use of mulch has become an important means to improve the crop growth environment, control weed growth, and maintain soil moisture and temperature. Traditional mulching technology usually relies on manual or simple mechanical equipment to complete the laying of mulch, which is not only inefficient, but also difficult to ensure the quality and uniformity of the mulch.

[0003] However, the existing mulching devices mostly rely on the ridge body being well shaped in advance. For the original or unfinished ridge body, these devices are often difficult to adapt, resulting in poor mulching effect. Therefore, there is an urgent need for a device that can simultaneously shape the ridge body during the mulching process, ensure the close fit between the ground film and the ridge body, and improve the mulching efficiency and quality. Utility Model Content

[0004] Based on the above, the utility model provides a ridge shaping and film pressing device to overcome the shortcomings of the prior art.

[0005] The technical solution of the utility model is: a ridge shaping and film pressing device, comprising:

[0006] The frame unit comprises a film covering frame, a film rolling drum, a running wheel and a soil guide wheel, wherein the film rolling drum is rotatably mounted on the film covering frame, the running wheels are mounted on both sides of the film covering frame, and the soil guide wheels are mounted on both sides of the rear end of the film covering frame;

[0007] The ridge-shaping unit includes a shaping plate, a film pressing plate and a film pressing wheel. The shaping plate is arranged at the front end of the film covering frame, and the shaping plate matches the surface of the standard ridge body. The film pressing plate is arranged between the film rolling drum and the soil guide wheel. The film pressing plate is arc-shaped, and a plurality of film pressing wheels are installed at intervals at the bottom of the film pressing plate.

[0008] In one example, the film laminating frame includes two longitudinal bars and two transverse bars, which are connected in sequence to form a frame structure, and the film roll can be rotatably installed between the two longitudinal bars.

[0009] In one example, at least two guide rods are provided on the top of the film pressing plate, the guide rods are movably mounted on the cross bar, and the guide rods are located between the film pressing plate and the cross bar and are provided with springs.

[0010] In one example, the front end of the shaping plate is in an eight-shaped shape, and a baffle is provided on the upper side of the front end of the shaping plate.

[0011] In one example, the shaping plate is fixed to the laminating frame via a bracket.

[0012] In one example, the lamination plate and the shaping plate have the same longitudinal cross-sectional shape.

[0013] The beneficial effects of the utility model are as follows: through the setting of the shaping plate, the film pressing plate and the film pressing wheel, during the film covering process, the shaping plate first shapes the surface of the ridge body, and then the film pressing plate and the film pressing wheel can press the ground film onto the ridge surface, thereby improving the film covering effect. In addition, the front end of the shaping plate is in an eight-shaped shape, and a baffle is provided on the upper side of the front end of the shaping plate. In this way, when the ridge surface is trimmed, the excess soil on the top of the ridge body will be diverted to the two sides of the ridge surface under the action of the baffle to fill the gaps on both sides, and the excess soil will be guided from the two side edges to the edge of the ridge surface or into the ridge ditch, which is convenient for the subsequent soil guiding and film covering by the soil guide wheel. The guide rod and spring structure on the top of the film pressing plate enable the film pressing plate to adapt to the ups and downs of the ridge surface, thus avoiding damage to the ground film caused by hard contact.

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0023] See also Figures 1 to 3, this embodiment provides a ridge shaping and film pressing device, including a frame unit and a ridge shaping unit.

[0024] The frame unit includes a film covering frame 11, a film rolling drum 12, a walking wheel 13 and a soil guide wheel 14. The film covering frame 11 includes two longitudinal rods 111 and two transverse rods 112, and the two longitudinal rods 111 and the two transverse rods 112 are connected in sequence to form a frame structure. The film rolling drum 12 is rotatably installed between the two longitudinal rods 111 near the front end, and the walking wheels 13 are installed on both sides of the middle part of the film covering frame 11. The distance between the two walking wheels 13 is the distance between two adjacent furrows. Two soil guide wheels 14 are installed on both sides of the rear end of the film covering frame 11, and they are installed tilted inward so as to guide the soil at the edge of the furrow or ridge body to the ground film when moving.

[0025] The ridge-shaping unit includes a shaping plate 21, a film pressing plate 22 and a film pressing wheel 23. The shaping plate 21 is installed at the front end of the film covering frame 11 through a bracket 24. The shaping plate 21 matches the surface of the standard ridge body and can trim the shape of the ridge body when moving. The film pressing plate 22 is installed between the film rolling drum 12 and the soil guide wheel 14. The film pressing plate 22 is arc-shaped. The longitudinal cross-sectional shape of the film pressing plate 22 is the same as that of the shaping plate 21. Multiple film pressing wheels 23 are installed at intervals at the bottom of the film pressing plate 22. The ground film released by the film rolling drum 12 is attached to the ridge surface after being pressed by the film pressing wheel 23.

[0026] In order to improve the ridge surface finishing effect, the front end of the shaping plate 21 is in an eight-shaped shape, that is, the middle part thereof protrudes forward, and the two side parts are inclined backward, and a baffle 25 is provided on the upper side of the front end of the shaping plate 21. In this way, when the ridge surface is trimmed, the excess soil on the top of the ridge body will be diverted to the two sides of the ridge surface under the action of the baffle 25 to fill the gaps on both sides, and the excess soil will be guided from the two side edges to the edge of the ridge surface or the ridge ditch, so as to facilitate the subsequent soil guiding and covering by the soil guide wheel 14.

[0027] In order to prevent the film pressing wheel 23 from making hard contact with the ridge surface and damaging the ground film, two guide rods 26 are installed on both sides of the top of the film pressing plate 22. The guide rods 26 can be movably installed on the cross bar 112, and a spring 27 is installed between the guide rods 26 and the cross bar 112, so that the entire film pressing plate 22 can adapt to the undulating ridge surface and avoid scratching the ground film due to hard contact with the ridge surface.

[0028] The working principle of the above-mentioned ridge shaping and film pressing device is as follows:

[0029] When covering the film, the device is moved to one end of the ridge body and connected to a micro-tillage machine, etc. When the device moves forward, the shaping plate 21 first corrects the shape of the ridge surface, and then the film drum 12 gradually releases the film, which is pressed against the ridge surface by the film pressing wheel 23 and fits the ridge surface. Then, the soil guide wheel 14 guides the soil at the edge of the ridge ditch or ridge body to the edges of both sides of the film, thereby realizing the film covering operation.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
