DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail an adjustable ridging device of the present utility model with reference to the drawings.
[0022] As Figures 1-5As shown in the figure, the adjustable ridging device of the present utility model includes a ridging plate 1 and a connecting plate 2. The ridging device is externally installed on a ridging frame 3 through the connecting plate 2, and then connected to a corresponding power machine through the ridging frame 3. The ridging plate 1 and the connecting plate 2 are detachably and fixedly connected, and a corresponding connecting device 4 is provided between the two. Under the action of the connecting device 4, the ridging plate is adjustable at multiple angles relative to the connecting plate 2. By adjusting the ridging plate 1 at multiple angles, the ridging device realizes the ridging requirements of various different ridge widths, ridge heights and ridge surface widths.
[0023] The connecting device 4 includes fixing ears and a connecting arm. A pair of fixing ears are respectively provided on the outer side of the ridging plate 1 and the inner side of the connecting plate 2. The two pairs of fixing ears are vertically corresponding. Each pair of fixing ears consists of two corresponding ear plates. The fixing ear fixedly installed on the outer side of the ridging plate 1 is the first fixing ear 11. In this embodiment, the first fixing ear 11 consists of two vertically corresponding parallel ear plates. The fixing ear fixedly installed on the inner side of the connecting plate 2 is the second fixing ear 21. The second fixing ear 21 consists of two horizontally corresponding parallel ear plates. A corresponding connecting arm is provided between the first fixing ear 11 and the second fixing ear 21. This connecting arm is the first connecting arm 41. The two ends of the first connecting arm 41 are respectively correspondingly connected to the first fixing ear 11 and the second fixing ear 21. Connecting ears corresponding to the first fixing ear 11 and the second fixing ear 21 are provided at the two ends of the first connecting arm 41. The first connecting arm 41 is rotatably connected to both the first fixing ear 11 and the second fixing ear 21, and the rotation axis between the first connecting arm 41 and the first fixing ear 11 is perpendicular to the rotation axis between it and the second fixing ear 21. Locking devices for controlling rotation are provided at both ends of the first connecting arm 41. At the outer end of the first connecting arm 41, a pair of connecting ears extending outward from its upper and lower end faces are formed. This pair of connecting ears are a pair of horizontal connecting ears 411 corresponding to the second fixing ear 21. At the inner end of the first connecting arm 41, a pair of connecting ears extending outward from its front and rear end faces are formed. This pair of connecting ears are a pair of vertical connecting ears 412 corresponding to the first fixing ear 11. Corresponding connecting holes are provided on the fixing ears and the connecting ears. The fixing ears and the first connecting arm 41 are installed in cooperation with a corresponding connecting shaft passing through the connecting holes and a corresponding nut. At the same time, the connecting shaft and the corresponding nut cooperate as a locking device to control the rotation between the connecting arm and the fixing ear. The connecting shaft between the first vertical plate and the first connecting arm 41 is the first connecting shaft 51, and the connecting shaft between the second fixing ear 21 and the first connecting arm 41 is the second connecting shaft 52. When the nut corresponding to the first connecting shaft 51 is loosened, the first fixing ear 11 can swing up and down with the first connecting shaft 51 as the axis, thereby changing the angle between the ridging plate 1 and the connecting plate 2 in the vertical direction. After adjustment, by tightening the nut corresponding to the first connecting shaft 51, the angle between the ridging plate 1 and the connecting plate 2 in the vertical direction no longer changes. When the nut corresponding to the second connecting shaft 52 is loosened, the first fixing ear 11 can swing back and forth with the second connecting shaft 52 as the axis through the first connecting arm 41, thereby changing the horizontal included angle between the ridging plate 1 and the connecting plate 2. Through the cooperation of the above two, the height of the corresponding ridge and the slope of the ridging slope can be changed. After adjustment, by tightening the nut corresponding to the second connecting shaft 52, the included angle between the ridging plate 1 and the connecting plate 2 in the horizontal direction no longer changes. During use, the change in the angle between them in the vertical and horizontal directions can affect the height of the ridge, the slope of the ridge, and further affect the ridge width and the width of the ridge surface. Specifically, the larger the vertical included angle between them, the greater the inclination of the ridging plate 1 in the vertical direction, and the narrower the formed soil ridge surface. On the contrary, the smaller the included angle between them,The smaller the inclination of the ridging plate 1 in the vertical direction, the wider the formed ridging surface. The larger the angle between the ridging plate 1 and the connecting plate 2 in the horizontal direction, the higher the ridging formed after the front cultivated soil is collected. On the contrary, the smaller the angle between the ridging plate 1 and the connecting plate 2 in the horizontal direction, the lower the height of the ridging formed by the cultivated soil collected during use.
[0024] A regulating nut 6 is provided below the first connecting arm 41. A corresponding regulating bolt 61 passes through the regulating nut 6. The regulating bolt 61 is parallel to and corresponds to the first connecting arm 41. The top of the regulating nut 6 is fixedly connected to the bottom surface of the first connecting arm 41 on the side close to the first fixing ear 11. The bottom end of the regulating bolt 61 abuts against the outer side surface of the ridging plate 1 below the first fixing ear 11. The regulating bolt 61 can be flexibly moved left and right relative to the regulating nut 6 by rotation, so as to adjust the distance between the regulating nut 6 and the outer side surface of the ridging plate 1. As the distance between the two changes, the first fixing ear 11 can be assisted to change the angle between the ridging plate 1 and the connecting plate 2 in the vertical direction.
[0025] Behind the first fixing ear 11 on the outer side of the ridging plate 1, there is a third fixing ear 12. In this embodiment, the third fixing ear 12 has the same structure as the first fixing ear 11. The two ear plates of the third fixing ear 12 are parallel to the two ear plates of the first fixing ear 11, and the four ear plates are in the same plane. On the outer side of the third fixing ear 12, there is a second connecting arm 42. The structure of the second connecting arm 42 is the same as that of the first connecting arm 41, and its length is not greater than half of the first connecting arm 41. The third fixing ear 12 and the second connecting arm 42 are rotatably connected. The two are installed by passing the corresponding third connecting shaft 53 through the reserved corresponding connecting holes, and the third connecting shaft 53 and the corresponding nut cooperate as a locking device to control the rotation between the two. The axis of the third connecting shaft 53 is on the extension line of the axis of the first connecting shaft 51. Loosen the nut corresponding to the third connecting shaft 53. When the first fixing ear 11 swings up and down with the first connecting shaft 51 as the axis, the third fixing ear 12 makes a synchronous movement with the third connecting shaft 53 as the axis under the drive of the ridging plate 1. After the vertical angle between the ridging plate 1 and the connecting plate 2 is adjusted, simultaneously tighten the nuts corresponding to the first connecting shaft 51 and the third connecting shaft 53. Rotate the adjusting bolt 61 to the appropriate position of the adjusting nut 6 so that its bottom end abuts against the outer side surface of the ridging plate 1. The vertical included angle between the ridging plate 1 and the connecting plate 2 is adjusted and can be fixed without further change. Behind the second fixing ear 21 on the inner side of the connecting plate 2, there is a fixed connecting arm 22 corresponding to the second connecting arm 42. In this embodiment, the two are parallel and corresponding in the same horizontal plane. The fixed connecting arm 22 is fixed on the corresponding inner side surface of the connecting plate 2 through the base at its outer end. Between the second connecting arm 42 and the fixed connecting arm 22, there is a rail plate 43. In this embodiment, a pair of corresponding rail plates 43 are provided between the second connecting arm 42 and the fixed connecting arm 22. The two corresponding rail plates 43 are exactly the same and parallel to each other. The two rail plates 43 are respectively located on the upper and lower sides of the second connecting arm 42 and are connected to the two respectively. Among them, the rail plate 43 and the second connecting arm 42 are rotatably connected, and the rail plate 43 and the fixed connecting arm 22 are slidably connected. The rail plate 43 is provided with a corresponding track 44. In this embodiment, the track 44 is arc-shaped. The rail plate 43 and the second connecting arm 42 are connected together by passing the corresponding fourth connecting shaft 54 through the track 44 and the connecting hole corresponding to the outer side of the second connecting arm 42 in sequence. The fourth connecting shaft 54 and the rail plate 43 are slidably connected. With the cooperation of the fourth connecting shaft 54, a pair of rail plates 43 are respectively fixed on the upper and lower sides of the second connecting arm 42, and both of the two rail plates 43 can rotate around the fourth connecting shaft 54. The tail end of the fourth connecting shaft 54 is provided with a corresponding nut for its installation. The fourth connecting shaft 54 and the corresponding nut cooperate as a locking device to control the rotation between the two. The other side of the rail plate 43 is slidably connected to the fixed connecting arm 22 through the track 44. The upper and lower ends of the inner side end of the fixed connecting arm 22 extend outward to form a pair of fixed connecting ears 221.The fixed connection ear 221 is provided with a through hole 222 corresponding to the track 44 of the rail plate 43. The corresponding screw 5 passes through the track 44 and the through hole 222 in sequence, and a corresponding tightening nut is provided at its tail end. When the tightening nut is not tightened, the screw 5 and the track 44 are in a sliding connection. At this time, when the first fixed ear 11 swings back and forth around the second connecting shaft 52 through the first connecting arm 41, the screw 5 slides in the track 44 accordingly. The position of the screw 5 on the track 44 changes with the adjustment of the horizontal angle between the ridging plate 1 and the connecting plate 2. After the horizontal angle between the ridging plate 1 and the connecting plate 2 is adjusted, the nuts corresponding to the second connecting shaft 52 and the tightening nut are tightened together, and the position of the screw 5 in the track 44 can be fixed, thereby preventing the change of the horizontal angle between the ridging plate 1 and the connecting plate 2. The cooperation of the screw 5 and the track 44 can prevent the uneven ridging caused by the change of the horizontal angle between the ridging plate 1 and the connecting plate 2 during the use of the ridging device. The above settings increase the firmness during the connection adjustment between the ridging plate 1 and the connecting plate 2.
[0026] Furthermore, when the ridging device is used externally, it is installed on the ridging frame 3 in pairs. The two paired ridging devices are respectively installed on the left and right sides of the ridging frame 3, and the two are in a left-right mirror image correspondence. The two ridging plates 1 of the two paired ridging devices correspond to each other. By simultaneously adjusting the vertical angles of the two ridging plates 1 and the corresponding connecting plates 2, the width of the corresponding ridging between the two can be changed. By simultaneously adjusting the horizontal angles of the two ridging plates 1 and the corresponding connecting plates 2 correspondingly, the height of the corresponding ridging between the two can be changed. In this way, one ridging can be completed at a time, which is more time-saving and labor-saving.
[0027] Furthermore, on the ridging frame 3, multiple pairs of ridging devices are installed side by side in sequence. The adjacent two pairs of ridging devices are closely arranged, and a reverse V-shaped plate fixedly connected to the ridging frame 3 is provided corresponding to the front of the adjacent two ridging devices. During use, it cooperates with the corresponding two ridging devices to work. In this way, multiple soil ridges can be formed at a time, which is more suitable for the ridging operation of large-area land.
[0028] During use, first install the ridging device on the ridging frame 3 of the externally connected power machine in front of it through the connecting plate 2. In this embodiment, a pair of ridging devices are installed on the ridging frame 3. Adjust the angles between the ridging plate 1 and the connecting plate 2 of the ridging device in the vertical and horizontal directions according to the requirements of the ridge width, ridge height, and ridge surface width. At this time, the two corresponding ridging plates 1 present a trapezoid shape that is wider at the front and narrower at the back, and wider at the bottom and narrower at the top. After the ridging device is adjusted, it can be used. Under the action of the power machine, the ridging device moves forward with the power machine. The cultivated soil on the front-end travel route of the ridging plate 1 is collected as it moves. Since the rear ends of the two corresponding ridging plates 1 gradually become narrower, the collected cultivated soil is piled up higher and stacked behind it. The cultivated soil collected by the right ridging device is stacked on its left rear, and the cultivated soil collected by the left ridging device is stacked on its right rear. Thus, under the combined action of a pair of corresponding ridging devices, the piled-up and stacked cultivated soil is squeezed into a trapezoidal soil ridge as the machine continues to move forward, and a soil ridge is formed.
[0029] The adjustable ridging device of the present utility model realizes multi-angle adjustment of the vertical and horizontal angles between the ridging plate 1 and the connecting plate 2. By adjusting the angle between the two, it can meet various different ridge widths, ridge heights, and ridge surface widths, enabling a single ridging machine to meet the different planting requirements of various crops for ridging, reducing the planting cost of ridged crops, and improving their economic benefits. The cooperation method of multiple groups of ridging devices can ridge multiple rows at one time, making ridging more time-saving and labor-saving, and is more suitable for crops planted on a large scale.
