[0020] The utility model aims to provide a ridge surface shaping device for a furrowing and soil-raising machine, so as to solve the problems existing in the prior art, improve the efficiency of ridging operation and reduce the work intensity.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model provides a ridge surface shaping device for a ditching and soil-raising machine, such as Figures 1 to 5 As shown, in this embodiment, the ridging machine body is provided with a driving mechanism 2 and a ridging structure, the ridging structure includes a bracket 50 and two ridging push plates symmetrically arranged on both sides of the bracket 50, the two ridging push plates are respectively a left ridging push plate 51 and a right ridging push plate 52, the lower fixed end 501 of each ridging push plate is rotatably connected to the bracket 50, and a transmission mechanism connected to the driving mechanism 2 is provided on the bracket 50, and the transmission mechanism is preferably a sprocket transmission mechanism 8, and the transmission mechanism has an eccentric The output shaft 80 and the bracket 50 are rotatably connected to a T-shaped connecting piece 53, one end of the first connecting rod 54 is rotatably connected to the eccentric output shaft 80, and the other end is rotatably connected to the first end of the T-shaped connecting piece 53, one end of the second connecting rod 55 is rotatably connected to the upper rotating end 502 of the left ridging pushing plate 51, and the other end is rotatably connected to the second end of the T-shaped connecting piece 53, one end of the third connecting rod 56 is rotatably connected to the upper rotating end 502 of the right ridging pushing plate 52, and the other end is rotatably connected to the third end of the T-shaped connecting piece 53.

[0023] The action principle of the ridging mechanism 5 provided by the utility model is as follows: Figure 4As shown, when the eccentric output shaft 80 is in the initial state, the first connecting rod 54 is at the lowest end, and the ridging push plates on the left and right sides are in a closed state; when the driving mechanism 2 drives the eccentric output shaft 80 to rotate 180°, as shown in FIG. Figure 5 As shown, the first connecting rod 54 installed on the eccentric output shaft 80 moves up to the highest end, driving the second connecting rod 55 to rotate 30-45°, and the ridging push plate fixed at one end on the bracket 50 rotates 30-45° under the drive of the second connecting rod 55 and the third connecting rod 56 respectively, at which time the ridging push plates on the left and right sides are in an open state. When the eccentric output shaft 80 rotates 180° again to return to the initial state, the ridging push plates on the left and right sides return to the original closed state. Driven by the drive mechanism 2 and driven by the sprocket, when the eccentric output shaft 80 rotates, the left and right ridging push plates are opened and closed back and forth, and the soil processed by the furrowing blade is pushed to both sides to realize the ridging operation.

[0024] The ridging machine body includes a frame 1, a walking wheel 4 arranged under the frame 1, an operating armrest 3 arranged on the frame 1, and a furrowing mechanism 6 arranged on the frame 1. The furrowing mechanism 6 includes a furrowing blade, a bracket 50 is fixedly arranged on the frame 1, and the walking wheel 4 is transmission-connected to the driving mechanism 2.

[0025] The ridging machine body also includes a gearbox transmission assembly 7 fixedly arranged on the frame 1 , and the travel wheels 4 and the transmission mechanism are both connected to the drive mechanism 2 through the gearbox transmission assembly 7 .

[0026] The drive mechanism 2 is driven by the gearbox transmission assembly 7, which drives the sprocket transmission mechanism 8 to move, drives the eccentric output shaft 80 to rotate, drives the first connecting rod 54 connected thereto to move up and down, and drives the second connecting rod 55 and the third connecting rod 56 to move up and down through the T-shaped connecting piece 53. Since the lower fixed ends 501 of the two ridging push plates are connected to the bracket 50, and the upper rotating ends 502 are respectively connected to the second connecting rod 55 and the third connecting rod 56, when the second connecting rod 55 and the third connecting rod 56 rotate and move up and down with the T-shaped connecting piece 53, the two ridging push plates on both sides are driven to rotate around their respective lower fixed ends 501, and the soil plowed by the furrowing blades is pushed to both sides to complete the ridging operation. The furrowing and ridging action is completed by the combined operation of the furrowing structure and the furrowing blades of the furrowing mechanism 6, and the mechanical method is replaced by the manual method, which improves the mechanization degree of the equipment, reduces the intensity of manual work, and improves the work efficiency.

[0027] The first connecting rod 54 , the second connecting rod 55 and the third connecting rod 56 are all telescopic rods. By changing the length of the first connecting rod 54 , the second connecting rod 55 or the third connecting rod 56 , the opening angle of the ridging push plate can be adjusted.

[0028] The first connecting rod 54, the second connecting rod 55 and the third connecting rod 56 each include a connecting rod shaft 57 and joint bearings 58 disposed at both ends of the connecting rod shaft 57. Each joint bearing 58 has a sleeve 59. The end of the connecting rod shaft 57 can extend into the sleeve 59 and be threadedly connected to the sleeve 59. By rotating the connecting rod shaft 57, the number of tightening circles between the connecting rod shaft 57 and the sleeve 59 can be adjusted, thereby changing the overall length of the first connecting rod 54, the second connecting rod 55 and the third connecting rod 56. According to the soil quality conditions, after plowing by the furrowing blade, when the ridging angle of the current ridging mechanism 5 cannot meet the requirements, the overall length of the second connecting rod 55 and the third connecting rod 56 is increased by tightening the connecting rod shaft 57 and the sleeve 59 of the second connecting rod 55 and the third connecting rod 56 for a number of turns. At the same time, by increasing the number of tightening the connecting rod shaft 57 and the sleeve 59 of the first connecting rod 54 for a number of turns and shortening the length of the first connecting rod 54, the opening angles of the ridging push plates on the left and right sides can be increased to adapt to the ridge surface shaping operation of soil with different moisture contents.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
