[0002] A rotary tiller is a tillage machine that is matched with a tractor to complete tillage and harrowing operations. Because of its strong soil crushing ability and flat surface after tillage, it has been widely used; at the same time, it can cut and crush the stubble buried below the ground surface, which is convenient for the operation of the seeder and provides a good seedbed for later sowing.

[0003] Chinese Patent Publication (Publication No.: CN217656930U) discloses a height adjusting device for an agricultural rotary tiller, including a rotary tiller body. The rotary tiller body includes a gantry and a cutter shaft. Through grooves are formed on both sides of the gantry. Fixed blocks are slidably installed inside the through grooves. An adjusting screw is also rotatably installed inside the through grooves. The adjusting screw is threadedly installed inside the fixed blocks. The upper end of the adjusting screw extends to the outside of the gantry and is installed with a sprocket. The two sprockets are connected by a chain drive. The upper end of one of the adjusting screws is installed with a rotary handle. Vertical plates are installed on one side of the two fixed blocks. The bottom of the vertical plate is of an arc-shaped structure. The cutter shaft is rotatably installed inside the two vertical plates.

Detailed implementation manners

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0028] As Figures 1-5 shown, the embodiment of the present utility model provides an agricultural rotary tiller height adjustment device, including a horizontal angle adjustment assembly 101, a height adjustment assembly 201, and a control panel 30;

[0029] The horizontal angle adjustment assembly 101 includes a top plate 10, a mounting plate 11, a support plate 12, a cylinder 13, a protective shell 14, and a scraper 15;

[0030] The top of the support plate 12 is fixedly connected to the bottom of the mounting plate 11, the bottom of the support plate 12 is hinged to the top of the top plate 10, the outer wall of the air cylinder 13 is fixedly connected to the bottom of the mounting plate 11, and the piston rod of the air cylinder 13 is hinged to the top of the top plate 10.

[0031] In one embodiment, one side of the protective shell 14 is fixedly connected to one side of the top plate 10, the top of the scraping plate 15 is mounted on the bottom of the protective shell 14. By setting the bottom of the support plate 12 to be hinged to the top of the top plate 10 and the piston rod of the air cylinder 13 to be hinged to the top of the top plate 10, when the ground to be rotary tilled is uneven left and right, the control panel 30 controls the air cylinder 13 to drive one side of the top plate 10 to flip, so that the top plate 10 drives the side plate 20 to flip, thereby enabling the side plate 20 to drive one end of the cutter shaft 26 to lift or lower, so as to adjust the horizontal angle of the rotary tillage blade 27, avoiding the problem of uneven soil tillage caused by left-right unevenness, improving the work efficiency. Through the setting of the protective shell 14, it can play a role in preventing soil splashing. When the rotary tiller is performing deep tillage, the protective shell 14 restricts the rotating soil inside the machine, avoiding soil splashing outside the vehicle, thereby ensuring the cleanliness of the cultivated land. At the same time, when the rotary tillage blade 27 is damaged and broken when tilling the land, the protective shell 14 can also prevent the broken rotary tillage blade 27 from flying out, avoiding harm to the staff. Through the setting of the scraping plate 15, the tilled land can be leveled, thereby improving the utilization efficiency of the land and the growth conditions of crops.

[0032] In one embodiment, the height adjustment assembly 201 includes two side plates 20, a through groove 21, a sliding groove 22, a sliding block 23, a lead screw 24, a driving motor 25, a cutter shaft 26 and rotary tillage blades 27; the tops of the two side plates 20 are fixedly connected to the bottom of the top plate 10, the through groove 21 is opened on one side of the side plate 20, the sliding groove 22 is opened on the inner side wall of the through groove 21, the outer wall of the sliding block 23 is slidably connected to the inside of the sliding groove 22, the outer wall of the driving motor 25 is fixedly connected to the top of the top plate 10, the output end of the driving motor 25 is fixedly connected to one end of the lead screw 24, the other end of the lead screw 24 is rotatably connected to the inner side wall of the sliding groove 22, the outer wall of the lead screw 24 is threadedly connected to the inside of the sliding block 23, one end of the cutter shaft 26 is rotatably connected to one side of the sliding block 23, and the inner side walls of a plurality of rotary tillage blades 27 are mounted on the outer wall of the cutter shaft 26. By controlling the driving motor 25 through the control panel 30 to drive the lead screw 24 to rotate, the lead screw 24 drives the sliding block 23 to move in the sliding groove 22, so that the sliding block 23 drives the cutter shaft 26 to move, thereby enabling the rotary tillage blades 27 to be quickly adjusted up and down, reducing the working time and improving the work efficiency.

[0033] In one embodiment, one side of the control panel 30 is mounted on one side of the support plate 12. An alarm 31 is mounted on one side of the support plate 12. The cylinder 13, the drive motor 25, and the alarm 31 are all electrically connected to the control panel 30. When the control panel 30 controls the cylinder 13 or the drive motor 25 to work, the alarm 31 emits a beep, thereby reminding the user and nearby personnel to pay attention to safety.

[0034] When the present utility model is working: First, install the present utility model at a designated position. Control the drive motor 25 through the control panel 30 to drive the lead screw 24 to rotate. The lead screw 24 drives the slider 23 to move in the chute 22, so that the slider 23 drives the cutter shaft 26 to move, making the rotary tillage blade 27 approach the ground. Observe whether the ground clearance heights of the left and right rotary tillage blades 27 are the same. When the ground to be rotary tilled is uneven on the left and right, control the cylinder 13 through the control panel 30 to drive one side of the top plate 10 to flip, so that the top plate 10 drives the side plate 20 to flip, thereby enabling the side plate 20 to drive one end of the cutter shaft 26 to lift or lower, so as to adjust the horizontal angle of the rotary tillage blade 27, avoiding the problem of uneven soil tillage caused by unevenness on the left and right, improving the working efficiency. At this time, control the drive motor 25 through the control panel 30 again to drive the lead screw 24 to rotate, so that the lead screw 24 drives the slider 23 to move in the chute 22, making the slider 23 drive the cutter shaft 26 to move, thereby adjusting the height of the rotary tillage blade 27, so that the tillage depth of the rotary tiller for the soil is more uniform, improving the land use efficiency and the growth conditions of crops.

[0035] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
