[0001] The utility model relates to the technical field of laying of weed-proof cloth, and particularly relates to an auxiliary fixing device for laying weed-proof cloth. Background Art

[0002] Weed-proof cloth, also called weed-killing cloth, is a non-woven fabric for fields that has good air permeability, fast water seepage, and is specifically used to prevent the growth of weeds. Black weed-proof cloth can effectively prevent sunlight from penetrating the ground and shining on the weeds below, control the photosynthesis of the weeds, and thus control the growth of the weeds.

[0003] Weed-proof cloth is widely used in agricultural planting. When applying weed-proof cloth, it is usually manually laid on the plot that needs to prevent weeds, and fixing nails are passed through the weed-proof cloth and inserted into the soil to fix the weed-proof cloth, so as to prevent the weed-proof cloth from being blown away by the wind. This laying method requires manual bending to lay, and a hammer or other knocking object is used to knock the fixing nails to achieve the effect of inserting the fixing nails into the soil. Therefore, it is easy to cause fatigue of the laying personnel and the laying efficiency is relatively low.

[0004] Based on this, it is necessary to design an auxiliary fixing device for laying weed-proof cloth that can achieve efficient laying and is convenient to use. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment: An auxiliary fixing device for laying a weed-proof cloth, as Figure 1 and Figure 2As shown in the figure, it includes a frame 1, a rotating shaft 2, a sliding frame 3, a limiting plate 31, a first cylinder 4 and a second cylinder 5. Rollers for facilitating the movement of the frame 1 are symmetrically installed on both left and right sides of the frame 1. A guide plate 10 for guiding the winding or releasing of the weed-proof cloth is provided on the front side of the top of the frame 1. Lifting blocks 11 for facilitating the lifting of the frame 1 are provided on the left and right side walls of the frame 1. The rotating shaft 2 is detachably installed on the left and right sides of the top of the frame 1 through protrusions. The rotating shaft 2 is used for winding and releasing the weed-proof cloth. The first cylinders 4 are installed on the outer walls of both left and right sides of the frame 1. The movable ends of the telescopic rods of the first cylinders 4 are respectively connected with two limiting plates 31. Arc-shaped grooves 30 are symmetrically opened on the opposite sides of the lower parts on the right sides of the two limiting plates 31. The diameter of the circle formed by the enclosure of the two arc-shaped grooves 30 is adapted to the diameter of the head of the fixing nail. A gap for the fixing nail of the weed-proof cloth to pass through is provided between the two limiting plates 31. A retaining piece 6 for blocking the fixing nail to limit the fixing nail in the two arc-shaped grooves 30 is provided between the lower parts of the two limiting plates 31. A sliding frame 3 is commonly installed on the two limiting plates 31. A chute adapted to the gap between the two limiting plates 31 is opened on the side of the sliding frame 3 facing the limiting plate 31. This chute is used for the head of the fixing nail to slide through. A second cylinder 5 is installed at the end of the sliding frame 3. The telescopic rod of the second cylinder 5 passes through the sliding frame 3. The movable end of the telescopic rod of the second cylinder 5 is connected with a pressing plate 51 for increasing the contact area with the fixing nail. The diameter of the pressing plate 51 is less than or equal to the diameter of the head of the fixing nail. When the fixing nail slides from the upper end of the limiting plate 31 to the lower end of the limiting plate 31, the telescopic rod of the second cylinder 5 extends downward to press the fixing nail downward.

[0019] As Figure 1 and Figure 3 shown in the figure, it further includes a cutting knife 7 and a third cylinder 9. The third cylinders 9 are installed on both left and right sides of the outer wall of the front part of the frame 1. The movable ends of the telescopic rods of the third cylinders 9 are commonly connected with a cutting knife 7. The cutting edge of the cutting knife 7 faces the outer wall of the front part of the frame 1. Through the extension movement of the telescopic rod of the third cylinder 9, the telescopic rod of the third cylinder 9 drives the cutting knife 7 to move towards the outer wall of the front part of the frame 1, thereby cutting the weed-proof cloth. A heating element 8 is provided on the back side of the cutting knife 7. The heating element 8 is used for heating the cutting knife 7. The setting of the heating element 8 can avoid the situation of the weed-proof cloth being drawn when cutting. After the heating element 8 heats the cutting knife, the weed-proof cloth is easily melted by heat when being cut by the cutting knife 7. Therefore, the situation of the weed-proof cloth being drawn due to the cutting action of the cutting knife 7 can be avoided.

[0020] During use, one end of the weed-proof cloth is fixed, and then the weed-proof cloth is released through the rotation of the rotating shaft 2 by moving the vehicle frame 1. The weed-proof cloth is guided and limited by the guide plate 10, thereby achieving the effect of efficiently laying the weed-proof cloth. During the laying process, when it is necessary to use fixing nails to fix the weed-proof cloth, first, through the contraction movement of the telescopic rod of the first cylinder 4, the lower end of the limiting plate 31 contacts the surface of the weed-proof cloth. Then, the fixing nail is placed in the gap between the two limiting plates 31. The vehicle frame 1 is moved, and the fixing nail slides downward along the gap between the two limiting plates 31 until it slides into the arc groove 30 below the limiting plate 31. Then, through the extension movement of the telescopic rod of the second cylinder 5, the telescopic rod of the second cylinder 5 extends downward, the pressing plate 51 moves downward to contact the top of the fixing nail, and gradually presses the fixing nail, thereby inserting the fixing nail into the ground to achieve the effect of fixing the weed-proof cloth. After the weed-proof cloth is fixed, the first cylinder 4 moves upward in extension, and the limiting plate 31 moves away from the weed-proof cloth. When it is necessary to cut the weed-proof cloth, the telescopic rod of the third cylinder 9 moves in extension, thereby pushing the cutting knife 7 against the outer wall of the front side of the vehicle frame 1 to cut the weed-proof cloth.

[0021] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
