Description

Technical Field

[0001] The utility model relates to the technical field of film laying machines, in particular to a soil covering device for film laying machines. Background Art

[0002] As a commonly used film laying equipment, the film laying machine is highly practical and can be used in various occasions. However, after laying the film, the ground film needs to be covered with soil for reinforcement. The existing equipment does not solidify the film evenly and does not compact the soil after covering, resulting in unsatisfactory soil covering and film solidification effects. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a soil covering device for a film laying machine, which is used to solve the problem that after the film laying machine lays the film, the soil covering device attached to the film laying machine solidifies the film unevenly and the soil is not compacted after covering, resulting in unsatisfactory soil covering and film solidification effect.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A soil covering device for a film laying machine comprises a soil covering trolley. Two soil taking shovels are arranged at the front end of the soil covering trolley. The spacing between the two soil taking shovels is greater than the width of the ground film. The inlet ends of the soil taking shovels are inserted into the ground. Two soil covering buckets are arranged at the rear end of the soil covering trolley. The soil covering buckets are of the same width as the ground film. A soil covering conveying trough is arranged between the soil taking shovels and the soil covering buckets. The soil covering conveying trough is located on the top of the soil covering trolley. A soil pressing wheel is arranged at the rear of the soil covering bucket through a connecting mechanism.

[0006] Furthermore, the connecting mechanism comprises a cross beam, the cross beam is arranged on the soil covering bucket, the cross beam is connected to a connecting rod, and the connecting rod is connected to a soil pressing wheel via a rotating shaft.

[0007] Furthermore, the wheels of the soil-covering trolley are crawlers.

[0008] Furthermore, the soil covering trolley is composed of left and right parts plugged into each other, the soil covering conveying trough is movably arranged on the top of the soil covering trolley, and the soil covering bucket is movably connected to the end of the soil covering trolley.

[0009] Furthermore, the connecting rod and the crossbeam are connected in an adjustable rotational manner.

[0010] Furthermore, the soil covering trolley is provided with a traction ring installed at one end of the soil taking shovel, and the traction ring is connected to the film laying machine.

[0011] Furthermore, a limit pin is installed at the end of the rotating shaft.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and is easy to install. The soil shovel digs soil from both sides of the ground film and transports it to the soil covering bucket through the soil covering conveying trough. The soil covering bucket evenly covers the soil on both sides of the ground film and then compacts it through the soil pressing wheel, thus avoiding the problems of uneven soil covering and unsatisfactory film solidification effect after traditional devices. The track has a lower ground contact ratio than the wheel type, which better protects the soil and avoids a greater impact on the soil during the film laying process. The tracks distributed on both sides prevent the utility model from directly contacting the ground film and affecting the ground film. The width of the soil covering trolley is adjusted according to the width of the ground film, which improves the practicality and adjustability of the utility model.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] A soil covering device for a film laying machine comprises a soil covering trolley 1, two soil taking shovels 2 are arranged at the front end of the soil covering trolley 1, the spacing between the two soil taking shovels 2 is greater than the width of the ground film, the soil taking shovels 2 are inserted into the ground, two soil covering buckets 3 are arranged at the rear end of the soil covering trolley 1, the soil covering buckets 3 are the same width as the ground film, a soil covering conveying trough 10 is arranged between the soil taking shovels 2 and the soil covering buckets 3, the soil covering conveying trough 10 is located at the top of the soil covering trolley 1, a cross beam 4 is arranged on the soil covering bucket 3, the cross beam 4 is connected with a connecting rod 5, the connecting rod 5 is connected with a soil pressing wheel 6 through a rotating shaft 8, and the soil pressing wheel 6 is located behind the soil covering bucket 3. The utility model has a simple structure and is easy to install. The soil taking shovel 2 digs soil from both sides of the ground film and conveys it to the soil covering bucket 3 through the soil covering conveying trough 10. The soil covering bucket 3 evenly presses the soil on both sides of the ground film, and then compacts it through the soil pressing wheel 6, thereby avoiding the problem of uneven soil covering and unsatisfactory film solidification effect in traditional devices.

[0021] The wheels of the soil covering vehicle 1 are crawlers, which are divided into left and right parts. Compared with the wheel type, the crawler has a lower ground contact pressure, which better protects the soil and avoids a greater impact on the soil during the film laying process. The crawlers distributed on both sides prevent the utility model from directly contacting the ground film and causing impact on the ground film.

[0022] The soil covering trolley 1 is composed of two parts connected to each other, the soil covering conveying trough 10 is movably arranged on the top of the soil covering trolley 1, and the soil covering bucket 3 is movably connected to the end of the soil covering trolley 1. The width of the soil covering trolley 1 is adjusted according to the width of the ground film, which improves the practicality and adjustability of the utility model.

[0023] The connecting rod 5 is rotatably connected to the cross beam 4. The connecting rod 5 is rotated according to the actual situation on site, and then positioned by the limit bolt 11, so as to change the height of the soil pressing wheel 6 and realize the change of the degree of soil covering and compaction.

[0024] The soil covering trolley 1 is provided with a soil taking shovel 2, one end of which is provided with a traction ring 9, and the traction ring 9 is connected to the film laying machine.

[0025] A limiting pin 7 is installed at the end of the rotating shaft 8 .

[0026] Example

[0027] The utility model is connected to a film laying machine through a traction ring 9, or farmers can follow the film laying progress of the film laying machine and independently complete the ground film covering with soil through the utility model. This embodiment takes the use of a film laying machine as an example. After the connection is completed, the film laying machine pulls the utility model forward, and the soil shovel 2 is inserted into the ground to dig soil, and the soil is transported to the soil covering bucket 3 through the soil covering conveying trough 10. The soil covering bucket 3 evenly covers the soil on both sides of the ground film, and then compacts it through the soil pressing wheel 6, thereby improving the soil covering quality.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
