Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, and in particular relates to a device for facilitating the laying of ground film. Background Art

[0002] Ground film laying refers to a measure of covering the ground surface with agricultural plastic film. First, it can reduce the impact of raindrops, prevent erosion and crust formation; second, it can effectively reduce the evaporation of soil moisture, retain soil moisture during droughts and increase soil moisture after rain, promote crop absorption and growth, and improve soil moisture utilization efficiency; third, it can keep the soil at a suitable temperature and humidity, slow down the drop in ground temperature and last for a long time, which is conducive to the decomposition and ripening of fertilizers and improve soil fertility. Ground film laying is usually done manually or by operating ground film laying machinery and equipment, but the current ground film laying machinery and equipment can only use ground film rolls of uniform width for laying, that is, the laying width of the ground film cannot be adjusted. When the ground film roll is wide, it cannot be installed on the equipment. When it is narrow, the shoveled soil cannot cover the two sides of the ground film, making the ground film unable to be fixed. Different crops have different requirements for ridge spacing, which brings many inconveniences to farmers. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provide a device that is convenient for laying ground film.

[0004] The utility model is realized by the following technical solutions:

[0005] The lifting of the lifting rod is symmetrical and is suspended in two groups, and the bottom of the lifting rod is symmetrical and suspended in two groups, and slide rails are arranged at the bottom of the left and right ends of the lifting rod, and two hydraulic cylinders are arranged on the middle lifting rod opposite to each other front and back; sliding sleeves are arranged at both ends of the moving rod, and the moving rod is mounted on the two ends of the slide rails through the sliding sleeves, and the output end of the hydraulic cylinder is fixedly connected to the moving rod, and the left end of the moving rod is provided with a supporting arm, and the top of the supporting arm is provided with a clamp, and a mulch reel is embedded in the clamp, and a guide wheel is hung on the moving rod at the lower right side of the mulch reel, and the right end of the moving rod is provided with a mounting groove, and a covering shovel is embedded in the mounting groove, and the shovel handle of the covering shovel is threadedly connected to the mounting groove.

[0006] Furthermore, a handle is provided at the top of the handle of the soil covering shovel.

[0007] Furthermore, the suspension beam and the suspension arm, the suspension arm and the slide rail, and the support arm and the moving rod are all connected by welding.

[0008] Furthermore, the bottom of the hydraulic cylinder is detachably connected to the boom.

[0009] Furthermore, the shovel mouth of the soil covering shovel is arranged to be inclined outward.

[0010] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model enables the moving rod to slide along the slide rails at both ends through the sliding sleeve through the extension and retraction of the hydraulic cylinder. Therefore, when the mulch film reel is removed, the two moving rods can be separated or the distance can be shortened through the hydraulic cylinder. When in use, the distance between the moving rods can be adjusted according to the width of the mulch film reel, so that the installation length of the mulch film reel is the same as the width of the mulch film reel, and the distance between the covering shovels at the rear end of the moving rods is also adjusted simultaneously with the width of the mulch film reel, so that the soil scooped up by the covering shovel can cover both sides of the mulch film, and the mulch film reel of appropriate width can be used to cover the ridges, which is suitable for the planting needs of different crops and improves the convenience of mulch film laying; 2. The utility model replaces the traditional manual operation of mulch film laying with mechanical equipment, which can save a lot of manpower, material resources and time, and is more suitable for the needs of contemporary agricultural development.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited by the embodiments. Example 1

[0015] like Figure 1-2The device shown in the figure is convenient for laying ground film, comprising a vehicle body 1 and a suspension frame installed at the rear of the vehicle body 1, the vehicle body 1 is an agricultural tractor, the suspension frame is composed of two parallel suspension beams 2, six suspension arms 5 and two moving rods 13, the suspension arms 5 are divided into three groups, two of which are symmetrically suspended and welded and installed below the left, middle and right parts of the suspension beam 2, the bottom of the suspension arms 5 at the left and right ends are provided with slide rails 8, the middle part of the slide rails 8 is divided into two points and is welded to the bottom of a group of suspension arms 5, and the middle suspension arm 5 is provided with two front and rear oppositely A hydraulic cylinder 11 is connected to the tractor power, and the bottom of the two hydraulic cylinders 11 is detachably connected to the bottom of the middle group of booms 5 through brackets, so that the hydraulic cylinders 11 are parallel to the slide rails 8 at both ends; both ends of the moving rod 13 are welded and installed with sliding sleeves 7, and the moving rod 13 is installed on the two ends of the slide rail 8 through the sliding sleeves 7. The moving rod 13 can be moved apart or together along the slide rail 8 through the sliding sleeves 7. The output end of the hydraulic cylinder 11 is fixedly connected to the moving rod 13 to control the extension of the piston rod in the hydraulic cylinder 11. When the movable rods 13 are extended, they are separated; when the movable rods 13 are retracted, they are brought together; a support arm 14 is provided at the left end of the movable rod 13; the bottom of the support arm 14 is welded to the movable rod 13; the height of the support arm 14 is lower than the cantilever beam 2; a clamp 3 is welded on the top of the support arm 14; a ground film reel 4 is embedded in the clamp 3; the ground film reel 4 can be quickly installed or removed by the clamp 3; a guide wheel 12 is hung on the movable rod 13 at the lower right corner of the ground film reel 4; the ground film is pressed to the ground by the guide wheel 12 On the surface, the right end of the moving rod 13 is provided with a mounting groove 9, and the mounting groove 9 is arranged on the outer side of the moving rod 13. A covering shovel 10 is embedded in the mounting groove 9. Threads are arranged inside the mounting groove 9 and on the shovel handle of the covering shovel 10. The shovel handle of the covering shovel 10 is threadedly connected with the mounting groove 9. A handle 6 is provided at the top of the shovel handle of the covering shovel 10, and the handle 6 is fixedly connected with the shovel handle.
