Description

Technical Field

[0001] This application relates to the field of agricultural cultivation technology, and in particular to a soil covering device for planting pigment peppers. Background Technology

[0002] In pepper cultivation, soil covering devices are mainly used to cover the root system, prevent lodging, maintain soil moisture and temperature, promote growth, reduce weed competition, and improve efficiency when used with transplanters and seeders. Manual soil covering tools are suitable for small-scale planting or replanting; they are flexible to operate but inefficient.

[0003] A search revealed that CN218851257U discloses an automatic soil covering device. In use, the device is connected to the rear end of agricultural machinery. Seeds are placed inside the hopper. As the equipment moves, the motor is started, causing one shaft to rotate, which in turn rotates the gear connected to it. Through the meshing of the gears, the other shaft rotates, resulting in the two augers rotating in opposite directions, thus loosening the soil. During this process, the seeds are separated by a partition and enter the hopper. Under their own weight, the seeds slide down to the ground through the guide plate and discharge port, thus achieving sowing. After sowing, a soil covering plate acts on the soil to cover the seeds.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: Although the above-mentioned device achieves a certain soil loosening effect, its trenching depth is fixed and not easy to adjust, making the device unsuitable for soil surfaces with complex terrain, thereby reducing the soil covering effect.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a soil covering device for planting pigment peppers. (Refer to...) Figures 1 to 5 The soil covering device for planting peppers includes a positioning plate 1, an unobstructed rotating arm 2, a movable plate 3, a soil covering wheel 4, an extension assembly 5, and a soil covering fine-tuning assembly 6. The positioning plate 1 is threaded to the outside of the small tractor, the unobstructed rotating arm 2 is rotatably connected to the outside of the positioning plate 1, the movable plate 3 is slidably connected to the inside of the unobstructed rotating arm 2, the soil covering wheel 4 is rotatably connected to the inside of the movable plate 3, the extension assembly 5 is installed on the outside of the unobstructed rotating arm 2, and the soil covering fine-tuning assembly 6 is installed on the outside of the soil covering wheel 4.

[0033] The positioning plate 1 is used to connect to the small tractor. The unobstructed swing arm 2 is used to limit the movement trajectory of the covering wheel 4 and extends in a straight line inside the groove of the unobstructed swing arm 2. The movable plate 3 is used to connect to the covering wheel 4. The covering wheel 4, together with the covering fine-tuning component 6, is used to fine-tune the trenching depth at the extended covering position. The extension component 5 is used to connect to and push the movable plate 3, and to control the working position of the covering wheel 4.

[0034] The soil covering fine-tuning component 6 includes a sliding chuck 61, a transverse abutment 62, an arc-shaped groove 63, a loosening tooth 64, a protrusion 65, and a compression spring 66. The sliding chuck 61 is sleeved on both ends of the soil covering wheel 4. The transverse abutment 62 is fixedly connected to the inner side of the sliding chuck 61, and the surface of the transverse abutment 62 abuts against the surface of the loosening tooth 64. The arc-shaped groove 63 is opened on the inner side of the soil covering wheel 4. The surface of the loosening tooth 64 is rotatably connected to the inner side of the soil covering wheel 4 located in the arc-shaped groove 63. The protrusion 65 is fixedly connected to the outer side of the transverse abutment 62. The two ends of the compression spring 66 are fixedly connected to the opposite side surfaces of the loosening tooth 64 and the protrusion 65, respectively.

[0035] If a quick depth adjustment is required, the set nut 8 can be manually rotated to lock or release the displacement allowance of the sliding chuck 61.

[0036] The extension assembly 5 includes a push cylinder 51, a push rod 52, a linear shaft 53, and a limiting plate 54. The push cylinder 51 is installed on the outside of the unobstructed rotating arm 2. The push rod 52 is fixedly connected to the outside of the output end of the push cylinder 51. The limiting plate 54 is fixedly connected to the outside of the push rod 52, and the inner side of the limiting plate 54 is fixedly connected to the surface of the movable plate 3. The linear shaft 53 passes through the interior of the limiting plate 54 and is fixedly connected to the surface of the unobstructed rotating arm 2.

[0037] The amount of pressure applied by the soil-covering wheel 4 is controlled by adjusting the pressure of the cylinder 51.

[0038] A stepper motor 7 is also provided on one side of the movable plate 3. The motor shaft of the stepper motor 7 is fixedly connected to one end of the soil covering wheel 4 through a coupling.

[0039] A set nut 8 is also provided at the connection between the sliding chuck 61 and the soil covering wheel 4.

[0040] A DC motor 9 and a rotating shaft 10 are also provided on the side of the positioning plate 1 near the unobstructed rotating arm 2. The output end of the DC motor 9 is fixedly connected to one end of the rotating shaft 10, and the outer wall of the rotating shaft 10 is welded to one side of the unobstructed rotating arm 2.

[0041] The process of using the soil covering device for peppers according to this embodiment is roughly as follows:

[0042] The positioning plate 1 is fixed to the reserved interface on the outside of the small tractor by threads, ensuring its horizontal stability. The DC motor 9 is started, driving the rotating shaft 10 to rotate the unobstructed swing arm 2 to the initial working position perpendicular to the tractor's direction of travel. The tractor's hydraulic system supplies air to the push cylinder 51, which pushes the push rod 52 outward along the linear axis 53. The push rod 52, through the limiting plate 54, drives the movable plate 3 to move linearly within the groove of the unobstructed swing arm 2 until the covering wheel 4 reaches the target row spacing position. During soil covering, the stepper motor 7 is turned on, driving the covering wheel 4 to rotate clockwise through the coupling. The tractor moves forward slowly, and the covering wheel 4 begins to cut into the soil. By adjusting the pressure of the push cylinder 51, the downward pressure of the covering wheel 4 is controlled. During operation, rotating the sliding chuck 61 causes the outer lateral abutment 62 to push the loosening teeth 64 to rotate along the inner side of the arc-shaped groove 63 of the covering wheel 4. The compression spring 66 ensures that the loosening teeth 64 are always stably connected with the protrusion 65, thereby achieving the angle adjustment effect of the loosening teeth 64 and controlling the cutting depth. When adjusting the row spacing, stop the tractor, reverse the air supply to retract the push cylinder 51, pull the covering wheel 4 back to a position close to the unobstructed swing arm 2, rotate the unobstructed swing arm 2 to a new angle via the DC motor 9, and then extend the push cylinder 51 to the new row spacing.

[0043] The beneficial technical effects of the soil covering device for peppers according to the embodiments of this application are roughly as follows:

[0044] This device, through the linkage of the soil covering fine-tuning component 6 and the extension component 5, adjusts the downward pressure of the soil covering wheel 4 and the cutting angle of the loosening teeth 64 in real time. On slopes and in uneven soil, the soil covering wheel 4 can automatically fine-tune the depth according to the terrain undulations to ensure uniform soil covering. The sliding groove structure of the unobstructed rotating arm 2 allows the movable plate 3 to freely extend and retract along the linear axis 53, and the working trajectory of the soil covering wheel 4 is not interfered with by the mechanical structure. In addition, the loosening teeth 64, through the arc-shaped groove 63, in conjunction with the compression spring 66 and the transverse abutment 62, can preset the trenching depth for different soil hardness, achieving a flexible adjustment effect.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
