Description

Technical Field

[0001] This utility model belongs to the technical field of land improvement, specifically relating to a non-woven fabric covering device for land improvement. Background Technology

[0002] my country has a wide distribution of saline-alkali land. Improving saline-alkali land and transforming it into land suitable for normal planting will play an important role in the development of agriculture.

[0003] There are many steps involved in improving saline-alkali land. One of them is to evenly lay non-woven fabric on the saline-alkali land. This can reduce the evaporation of water from the soil surface, regulate the soil temperature to a suitable level, and over time, increase the organic matter in the soil and effectively inhibit the rise of salt content.

[0004] In the preparation stage, the saline-alkali land must first be leveled, and stones, weeds, and other debris removed from the surface to ensure that the non-woven fabric can adhere tightly to the soil surface and guarantee the covering effect. The non-woven fabric is then evenly laid on the saline-alkali land, which can be done manually or mechanically. During the laying process, the edges of the non-woven fabric need to be fixed. The traditional method is to place a mound of soil behind the non-woven fabric and press it down to fix it after it is laid. This method is not only labor-intensive but also inefficient. The weight of the soil mound also depends on human experience, and the pressing effect cannot be guaranteed. To address the above problems, a more efficient non-woven fabric covering device for land improvement is proposed. Utility Model Content

Non-woven fabric is wound around the winding roller. An opening is provided on the base corresponding to the winding roller, and a uniform automatic feeding mechanism is provided on the base corresponding to the storage box. The uniform automatic feeding mechanism includes feeding holes symmetrically arranged between the base and the storage box. A transmission rod is rotatably connected inside the base, and a rotating block is rotatably connected inside the feeding holes. Symmetrically arranged arc-shaped grooves are provided on the rotating blocks. The transmission rod is fixedly connected to the rotating blocks and to one of the wheels.

[0024] Please refer to the accompanying diagrams for all instruction manuals:

[0025] A non-woven fabric covering device for land improvement includes a base 1, wheels 2 uniformly rotatably connected to the base 1, a storage box 3 fixedly installed on the base 1, supports 4 symmetrically fixedly installed on the base 1, a winding roller 5 rotatably connected to the support 4, a fixed damping mechanism on the support 4 corresponding to the winding roller 5, non-woven fabric wound and connected to the winding roller 5, an opening 7 on the base 1 corresponding to the winding roller 5, and a uniform automatic feeding mechanism on the base 1 corresponding to the storage box 3.

[0026] The uniform automatic feeding mechanism includes feeding holes 8 symmetrically arranged between the base 1 and the storage box 3. A transmission rod 9 is rotatably connected inside the base 1. A rotating block 10 is rotatably connected inside the feeding hole 8. An arc-shaped groove 11 is symmetrically provided on the rotating block 10. The transmission rod 9 is fixedly connected to the rotating block 10. The transmission rod 9 is fixedly connected to one of the wheels 2.

[0027] As described above, the take-up roller 5 is installed between the brackets 4 to pull out the non-woven fabric, move it to the bottom of the base 1 through the opening 7, fix the movable end, push the base 1 to move, and lay the non-woven fabric. As the wheel 2 rotates, it can drive the transmission rod 9 to rotate. The transmission rod 9 causes the rotating block 10 to rotate, so that the soil piles accumulated in the arc groove 11 are discharged in turn through the discharge hole 8 to the bottom of the base 1, pressing the non-woven fabric.

[0028] As a technical optimization of this utility model, the fixed damping mechanism includes a fixed rod 12 rotatably connected to the bracket 4, a screw 13 threadedly connected to the fixed rod 12, a fixed plate 14 rotatably connected to the lower end of the screw 13, a spring 15 fixedly installed below the fixed plate 14, and an arc plate 16 fixedly installed at the other end of the spring 15. The arc plate 16 is slidably connected to the winding roller 5.

[0029] As can be seen from the above description, the fixing rod 12 can be flipped, and during the replacement of the take-up roller 5, it can control the up and down movement of the take-up roller 5. By moving the screw 13, the fixing plate 14 can be moved downward, which in turn moves the spring 15 and the arc plate 16, so that the arc plate 16 contacts the take-up roller 5, so that the take-up roller 5 has a certain resistance when it rotates, which can limit the rotation of the take-up roller 5. When the base 1 suddenly stops, there will be no excess nonwoven fabric flowing out, ensuring efficient laying.

[0030] As a technical optimization of this utility model, a knob 17 is fixedly installed on the upper end of the screw 13;

[0031] As can be seen from the above description, knob 17 can easily control the rotation of screw 13.

[0032] As a technical optimization of this utility model, a push rod 18 is fixedly installed on the base 1;

[0033] As can be seen from the above description, the worker can notify the entire equipment to move by pushing lever 18.

[0034] As a technical optimization of this utility model, a ramp 19 is provided inside the storage box 3 corresponding to the material discharge hole 8;

[0035] As can be seen from the above description, the slope 19 can better guide the soil into the discharge hole 8.

[0036] As a technical optimization of this utility model, a feeding pipe 6 is fixedly installed on the lower side of the base 1 corresponding to the feeding hole 8;

[0037] As can be seen from the above description, the feed pipe 6 can more effectively transport the soil pile onto the nonwoven fabric, reducing the exposure time in the air.

[0038] The working process of this utility model is as follows:

[0039] Pre-fill the storage box 3 with a certain amount of soil; place the winding roller 5 wrapped with non-woven fabric on the bracket 4, rotate the fixing rod 12 so that the arc plate 16 is above the winding roller 5, rotate the knob 17 to control the screw 13 to rotate downward so that the arc plate 16 can fit against the winding roller 5 and provide a certain resistance; pull out the non-woven fabric, guide it through the opening 7, and enter the bottom of the base 1, and fix the non-woven fabric; push the base 1 to move by the push rod 18. As the wheel 2 rotates, it can drive the transmission rod 9 to rotate. The transmission rod 9 causes the rotating block 10 to rotate, so that the soil piles accumulated in the arc groove 11 are discharged in turn through the discharge hole 8 to the bottom of the base 1, pressing down the non-woven fabric.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
