Description

Technical Field

[0001] This utility model relates to the field of film laying machine technology, and in particular to a soil extraction and film covering device for a film laying machine. Background Technology

[0002] Film laying machines are commonly used film laying equipment in the field of agricultural planting. They are highly practical and can be used in a variety of occasions. They generally consist of a frame, furrow opener, film laying device, soil covering device, and film pressing rollers.

[0003] After the film-laying machine lays the film, it is necessary to reinforce both sides of the film with soil. Most existing soil-covering devices use power output to extract soil, which means that the film-laying machine needs to be powered to complete the soil extraction operation. The soil is then transported to the soil collection box of the film-laying machine through a conveying device, and the soil collection box covers the edges of the film with soil to reinforce the film. Therefore, it consumes the power of the film-laying machine, resulting in high power consumption and high production costs during the operation. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a soil extraction and film covering device for a film laying machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a soil-taking and film-covering device for a film-laying machine, comprising mounting frames arranged on both sides of the film-laying machine, a horizontally arranged rotating shaft at the bottom of the mounting frame, a soil-taking wheel rotatably mounted on the rotating shaft, a fixing plate fixedly mounted on the rotating shaft outside the soil-taking wheel, a plurality of soil-collecting troughs arranged in a ring array on the outer periphery of the side of the soil-taking wheel near the fixing plate, the opening of the soil-collecting troughs being located on the side of the soil-taking wheel near the fixing plate, the bottom of the troughs being an inclined surface extending from the side of the soil-taking wheel towards the wheel rim, a soil inlet being provided on the trough wall on the side of the soil-collecting trough near the wheel rim, a plurality of soil-taking components arranged in a ring array on the wheel rim of the soil-taking wheel corresponding to the soil inlet, and a soil outlet of the same size as the opening of the soil-collecting trough being provided at the upper edge of the fixing plate.

[0006] Furthermore, the soil sampling assembly includes a surrounding plate disposed at the soil inlet on both sides of the soil sampling wheel along the thickness direction, and a baffle at the soil inlet on the rear side of the soil sampling wheel along the forward direction. The two ends of the baffle are connected to the surrounding plates on both sides to form a soil sampling trough.

[0007] Furthermore, a soil collection trough is provided on the rear side of the soil-collecting wheel. The opening of the soil collection trough faces the forward direction of the soil-collecting wheel, and the bottom of the trough is arc-shaped. An installation hole is provided on the side of the soil collection trough near the fixing plate for fixing to the fixing plate with screws.

[0008] Furthermore, the soil collection trough is entirely covered behind the soil-collecting wheel.

[0009] In summary, this utility model has the following beneficial effects: In this application, by setting a rotating shaft, a soil-collecting wheel, a fixing plate, a soil storage trough, and a soil-collecting component, the soil-collecting component is connected to the soil storage trough through the soil inlet. As the film-laying machine moves forward, the soil-collecting wheel will rotate with the soil-collecting component, loading soil into the soil-collecting component. As the soil-collecting component moves upward from the rear side of the soil-collecting wheel, the collected soil enters the soil storage trough from the soil inlet. When the soil-filled soil storage trough is about to move directly to the top, the opening of the soil storage trough begins to overlap with the soil outlet on the fixing plate. Under the action of the inclined surface at the bottom of the soil storage trough, the soil in the soil storage trough flows out from the soil outlet and covers the two sides of the film, completing the soil collection and film covering work. The soil-collecting wheel can be driven to rotate simply by the movement of the film-laying machine, without the need to provide additional power to the soil-collecting wheel, saving energy and reducing costs.

[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] like Figure 1-4As shown in the illustration, this application discloses a soil-collecting and mulching device for a film-laying machine, including a mounting frame, a rotating shaft 10, a soil-collecting wheel 20, a fixing plate 30, and a soil-collecting assembly 40. The mounting frame is mounted on the film-laying machine at both edges of the mulch film. A horizontally arranged rotating shaft 10 is located at the bottom of the mounting frame. The soil-collecting wheel 20 is rotatably mounted on the rotating shaft 10, and the soil-collecting assembly 40 is mounted on the soil-collecting wheel 20. A fixing plate 30 is fixedly mounted on the rotating shaft 10 outside the soil-collecting wheel 20. Specifically, the fixing plate 30 is located on the inner side and near the edge of the mulch film being laid, the soil-collecting wheel 20 is located on the outer side, and the inner side of the soil-collecting assembly 40 is outside the edge of the mulch film. The mounting frame has a lifting function, meaning the soil-collecting wheel 20 can be raised or lowered by adjusting the mounting frame. When the film laying machine is not in operation, the soil-collecting wheel 20 is suspended in the air by adjusting the mounting frame to avoid contact between the soil-collecting wheel 20 and the ground. When the film laying machine is in operation, the soil-collecting wheel 20 is lowered to the lowest soil-collecting component 40 and inserted into the ground by adjusting the mounting frame. So that when the film laying machine moves forward, the soil-collecting wheel 20 can drive the soil-collecting component 40 to rotate and collect soil.

[0017] Specifically, a plurality of soil storage troughs 21 are arranged in a ring array on the outer periphery of the side of the soil-collecting wheel 20 near the fixing plate 30. The opening of the soil storage trough 21 is located on the side of the soil-collecting wheel 20 near the fixing plate 30, and the bottom of the trough is an inclined surface extending from the side of the soil-collecting wheel 20 towards the wheel rim. A soil inlet 22 is provided on the wall of the soil storage trough 21 on the side of the wheel rim of the soil-collecting wheel 20. A plurality of soil-collecting components 40 are arranged in a ring array on the wheel rim of the soil-collecting wheel 20 corresponding to the soil inlet 22. The soil-collecting components 40 include a surrounding plate 41 located on both sides of the soil inlet 22 in the thickness direction and a baffle 42 located on the rear side of the soil inlet 22 in the forward direction of the soil-collecting wheel 20. The two ends of the baffle 42 are connected to the two surrounding plates 41 to form a soil-collecting trough, which is used to collect soil from the ground into the soil storage trough 21 when the soil-collecting wheel 20 rolls.

[0018] A soil outlet with the same size as the opening of the soil storage trough 21 is provided at the upper edge of the fixed plate 30. When the soil storage trough 21 containing soil is rotated to the top, the opening of the soil storage trough 21 overlaps with the soil outlet, so that the soil in the soil storage trough 21 can flow out from the soil outlet.

[0019] Specifically, a further configuration includes a soil collection trough 50 located behind the soil-collecting wheel 20. The opening of the soil collection trough 50 faces the forward direction of the soil-collecting wheel 20, and the bottom of the trough is arc-shaped. An mounting hole 51 is provided on the side of the soil collection trough 50 near the fixing plate 30. The fixing plate 30 has several corresponding connecting holes, and the soil collection trough 50 is fixedly connected to the fixing plate 30 using screws. The soil collection trough 50 completely covers the rear of the soil-collecting wheel 20 to prevent soil from being thrown behind by the rolling action of the soil-collecting wheel 20 after the soil-collecting assembly 40 has collected all the soil.

[0020] The working principle of the soil-collecting and mulching device for a film-laying machine in this embodiment is as follows: During operation, the soil-collecting wheel 20 is lowered to the lowest point, and the soil-collecting component 40 is inserted into the ground, adjusted by the mounting frame. As the film-laying machine moves forward to lay the film, the soil-collecting wheel 20 rolls along with it, causing the soil-collecting component 40 to continuously insert into the ground and carry soil up. When the soil-collecting component 40 moves upward behind the soil-collecting wheel 20, the soil enters the soil storage tank 21 through the soil inlet 22. When the soil storage tank 21, which is filled with soil, rotates to the top, the opening of the soil storage tank 21 overlaps with the soil outlet, allowing the soil in the soil storage tank 21 to flow out from the soil outlet and cover the laid mulch film. Since several soil storage tanks 21 and soil-collecting components 40 are arranged in a circular array, continuous soil collection and mulching can be achieved.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
