The single-trellis structure is the most widely trellis structure adopted by densely planted grapes in current domestic and foreign production, and is suitable for large-scale flat-land vineyards. The surface of the hedge frame is vertical to the ground, and the branches and tendrils of the grapes are distributed on the surface to form a hedge wall shape, so the hedge frame is called as a hedge frame. When the single hedge frame is built, a row of upright columns is arranged along the planting row direction of the grapes, the distance between the upright columns and the planting row of the grapes is 30-40 cm, and the frame surface is vertical to the ground. The height of the frame is determined by the line spacing, and is generally 150-180 cm. 2-4 iron wires are transversely pulled on the frame. The specific application is that the elevating and the number of the iron wires are determined according to the conditions of variety, tree form, climate, soil and the like.

the angle adjustment device 703 comprises a slide block 706 and three guide rods 707, the direction of movement q of the angle adjustment device 703 forms an angle α (fig. 2) with the horizontal plane,
the two ends of each guide rod 707 are fixed on the support frame 701, the included angle formed by the extension direction of the three guide rods 707 and the horizontal plane is equal to the degree of the included angle α, the included angle formed by the plane A714 formed by the three guide rods 707 and the horizontal plane is equal to the degree of the included angle α,
the sliding block 706 is arranged on the three guide rods 707 and can move along the extending direction of the three guide rods 707, and the tensile rope 705 can be wound out from the lower side surface of the sliding block 706 on the plane A714;
the sliding block 706 is sleeved on the three guide rods 707, wherein the middle guide rod 707 is a threaded lead screw, the threaded lead screw is in threaded connection with the sliding block 706, the threaded lead screw is driven by the motor 716 to rotate axially, and the sliding block 706 is controlled to slide upwards or downwards along the direction of the lead screw by adjusting the rotating direction of the threaded lead screw; thereby controlling the height and the pulling angle of the tensile rope 705, and simultaneously controlling the rising or falling speed of the pulled upright post by controlling the sliding speed of the sliding block 706; in the process of pulling up or falling the whole stand column, the height difference between the height of the tension rope and the height difference of the stand column is always kept in a smaller numerical value, so that the stand column is guaranteed to have only a smaller height difference between the top end and the bottom when falling, and the condition that the stand column cannot be completely fallen is avoided.
In the hedge frame landing gear 7, the included angle α is an acute angle (as shown in fig. 2, the included angle α degree can be 45-80 degrees, and can be adjusted according to the actual situation), preferably 75 degrees, the labor saving principle is similar to that of an inclined plane, and the labor saving effect is achieved, and the smaller the inclined angle is, the smaller the force value is needed, namely, the angle adjusting device 703 slides along the inclined direction, so that the vertical downward acting force generated by the tension rope 705 on the angle adjusting device 703 is relatively smaller, the resistance of the angle adjusting device 703 during lifting is reduced, and the service life of related parts (such as a threaded lead screw described below) is prolonged;

the winding direction m of the tensile rope 705 at the angle adjusting device 703 is perpendicular to the winding direction n; since the second guiding wheel 709 mainly serves to support the tensile cord 705, the second guiding wheel 709 is in close contact with the tensile cord 705 wound by the first guiding wheel 708 without affecting the original tensile force, so the winding-in direction m and the winding-out direction n of the tensile cord 705 at the angle adjusting device 703 are perpendicular to each other, and when the winding-in direction m and the winding-out direction n of the tensile cord 705 at the angle adjusting device 703 are smaller than 90 °, the force applied to the tensile cord 705 at the second guiding wheel 709 increases, which results in an increase in the final required tensile force, i.e., the tensile force of the driving device 704 on the tensile cord 705.
The winding-out direction p of the tensile cord 705 in the cord positioning portion 702 and the winding-in direction m of the tensile cord 705 in the angle adjusting device 703 are parallel to the moving direction q of the angle adjusting device 703;
all the winding paths of the tensile cord 705 are in the same plane;

the driving device 704 comprises a tension rope take-up pulley 711, and a wheel shaft 715 of the tension rope take-up pulley 711 is driven by a motor 716;
a fixed support member (e.g., six anchors 712) and a walking member (e.g., four ground wheels 713) are provided under the base 700 to facilitate fixing or moving;
the driving device 704 further comprises a tensile rope 705, one end of the tensile rope 705 sequentially winds through the angle adjusting device 703 and the pull rope positioning part 702 and then is connected with the driving device 704, and the other end of the tensile rope 705 winds out of the angle adjusting device 703 so as to be connected with a corresponding upright column conveniently;
the highest position of the pull rope 705 wound by the angle adjusting device 703 is higher than the highest position of the pulled column body, so that the column body is always pulled (erected or laid down) from the upper part.
The method of use and operation of the above described hedge landing gear 7 is as follows:
in operation, the hedge frame landing gear 7 is moved to the side of the column by the ground wheels 713, the bottom base 700 is unfolded and fixed to the ground by the ground feet 712, and the sliding block 706 can move up and down along the guide rod 707 to change the direction and angle of the pulling tension rope 705 (iron wire).
In the process of putting down the column or the hedge frame, the sliding block 706 slowly moves downwards along the guiding rod 707 from a position higher than the column, so as to ensure that the pulling rope 705 pulled at the top end of the column drives the column to slowly fall on the ground, and simultaneously drives the column and the whole hedge frame to be put down.
In the process of pulling up the upright post or the hedge frame, the sliding block 706 slowly moves upwards in an inclined manner along the guiding rod 707 from a position higher than the post body, so as to ensure that the pulling rope 705 for pulling up the post body is always higher than the post body, and the pulling rope 705 is pulled upwards in an inclined manner to drive the post body and the whole hedge frame where the post body is located to stand up.
Those not described in detail in this specification are within the skill of the art. The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
