Description

Technical Field

[0001] This application relates to the technical field of field ridging, and more particularly, to a ridging device and a ridging method. Background Art

[0002] Ridging in tobacco fields increases the thickness of the soil layer, which is beneficial for moisture conservation, drought prevention, drainage, waterlogging prevention, and disease prevention. It can also increase the soil surface area to receive more light and heat, raise the soil temperature, and promote crop growth. The most ideal ridge body soil layer structure for tobacco seedlings is loose at the bottom, medium-loose in the middle, fine and broken on the surface, and the ridge ditch and ridge surface are flat: the middle soil layer of the loose degree has a high moisture content, and a large amount of air between the gaps is convenient for maintaining a stable high soil temperature, which is beneficial for the growth of plant roots; the fine surface soil can block the rapid evaporation of the middle layer of water and has good moisture retention; the flat ridge ditch and ridge surface are conducive to realizing high-quality mechanical transplanting. An ideal seedbed is conducive to the quick greening and high survival rate of tobacco seedlings after transplanting.

[0003] Currently, in dry farming tobacco areas, the method of first digging pits and then transplanting tobacco seedlings is generally adopted. Usually, the operation steps are divided into three steps: first ridging, then digging pits, and finally transplanting. The ridging type used is a trough-like ridging type with extremely poor accuracy, and the ridging device used is a rotary tiller with a ditch plow attached. Due to the action of the ditch plow, there is less soil piled on the ridge top, and a groove is naturally formed in the middle of the ridge top surface. This ridging type has poor quality and is not convenient for subsequent pit digging and transplanting operations, resulting in low operation efficiency. Summary of the Invention

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0038] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] As Figure 1 shown, the trough-shaped ridge 200 has two grooves 201 and a ridge body located between the two grooves 201. The ridge body has a first slope surface 202, a second slope surface 203, a groove 204, a first top surface 205, and a second top surface 206. Such a regular trough-shaped ridge 200 has a flat surface, good linearity, and is convenient for the subsequent efficient operation of the pond-digging and transplanting integrated machine.

[0040] As Figures 2 to 5 shown, the embodiment of the present application provides a ridging device 100. The ridging device 100 can be mounted on a vehicle to move along with the vehicle in the driving direction, thereby ridging out the trough-shaped ridge 200. The vehicle can be a tractor, a three-wheeled vehicle, etc.

[0041] The ridging device 100 includes: a housing 10, a rotary tillage blade 20, a shaping plate 30, and a secondary shaping component 40.

[0042] The rotary tillage blade 20 is rotatably arranged in the housing 10 and is used for cutting the soil to achieve primary soil fragmentation. The primary soil fragmentation after cutting is thrown to the inner wall of the housing 10 to achieve secondary soil fragmentation. As an example, the rotary tillage blade 20 includes a rotating shaft and a plurality of blades arranged on the rotating shaft. The rotating shaft can be driven to rotate by a transmission shaft of a power vehicle, can also be driven to rotate by a motor, and can also be driven to rotate by a hydraulic system, an electrical system, etc.

[0043] The shaping plates 30 are arranged on the opposite sides of the housing 10. The shaping plates 30 and the housing 10 together stack up the soil blocks to form a ridge body. At the same time, the two shaping plates 30 respectively extrude the first slope surface 202 and the second slope surface 203 of the ridge body, forming a primary shaping of the slope surface of the ridge body. The bottom surface of the shaping plate 30 is lower than the first ridge slope pressing wheel 421, the second ridge slope pressing wheel 422, and the ridge top surface grooving wheel 423.

[0044] The secondary shaping assembly 40 is arranged between the two opposite shaping plates 30. The secondary shaping assembly 40 includes a mounting shaft 41 and a pressing wheel group 42 arranged on the mounting shaft 41. The pressing wheel group 42 includes a first ridge slope pressing wheel 421, a second ridge slope pressing wheel 422, and a ridge top surface grooving wheel 423. The first ridge slope pressing wheel 421, the second ridge slope pressing wheel 422, and the ridge top surface grooving wheel 423 are coaxial and arranged at intervals along the axial direction of the mounting shaft 41. The ridge top surface grooving wheel 423 is located between the first ridge slope pressing wheel 421 and the second ridge slope pressing wheel 422. Among them, the part of the mounting shaft 41 located between the first ridge slope pressing wheel 421 and the ridge top surface grooving wheel 423 constitutes a first ridge top surface flattening part 424; the part of the mounting shaft 41 located between the second ridge slope pressing wheel 422 and the ridge top surface grooving wheel 423 constitutes a second ridge top surface flattening part 425.

[0045] The secondary shaping assembly 40 can be without a power source. During the ridging operation, it can move along the driving direction following the ridging device 100. During the movement, the first ridge slope pressing wheel 421, the second ridge slope pressing wheel 422, and the ridge top surface grooving wheel 423 can freely rotate following the mounting shaft 41. The secondary shaping assembly 40 without a power source can reduce the equipment cost and the failure rate. In addition, the freely rotating first ridge slope pressing wheel 421, second ridge slope pressing wheel 422, ridge top surface grooving wheel 423, and mounting shaft 41 can improve the quality of the trough-shaped ridge.

[0046] The pressing wheel group 42 can be set in one set (one set) or multiple sets. The secondary shaping assembly 40 is located at the rear side in the forward direction of the driving direction.

[0047] The rotary tillage blade 20 is rotatably arranged in the housing 10, so that the cut soil is thrown to the inner wall of the housing 10 to achieve secondary soil crushing. Through the secondary soil crushing, the soil clods are finer, increasing the fluidity of the soil clods, facilitating the shaping plate 30 and the housing 10 to gather and pile up the soil clods into a ridge body; at the same time, the two shaping plates 30 respectively extrude the two slopes (the first slope 202 and the second slope 203) of the ridge body, forming a primary shaping of the slopes of the ridge body, so that the proportion of fine soil on the surface layer of the slopes of the ridge body is large, that is, the proportion of fine soil clods on the surface layer of the ridge body and large soil clods in the middle layer is relatively large, and the shaping plate 30 can also scrape the soil clods in the ridge trench, thereby leveling the ridge trench; the top of the ridge body is suppressed by the ridge top groove pressing wheel 423, the first ridge top flattening part 424 and the second ridge top flattening part 425, so that a groove 204 and two tops (the first top 205 and the second top 206) respectively located on both sides of the groove 204 are formed at the top of the ridge body, and, the first slope pressing wheel 421 and the second slope pressing wheel 422 respectively extrude the first slope 202 and the second slope 203 to complete the secondary shaping of the first slope 202 and the second slope 203, so that the first slope 202, the second slope 203, the groove 204, the first top 205 and the second top 206 of the formed trough-shaped ridge have higher flatness and better linearity, facilitating the efficient operation of the subsequent pond-digging and transplanting integrated machine.

[0048] In some embodiments, along the axial direction of the mounting shaft 41, the first slope pressing wheel 421 has a first conical surface 421a facing the ridge top groove pressing wheel 423, and the second slope pressing wheel 422 has a second conical surface 422a facing the ridge top groove pressing wheel 423; the outer diameters of the first slope pressing wheel 421 and the second slope pressing wheel 422 are the same and are both larger than the outer diameter of the ridge top groove pressing wheel 423.

[0049] The first conical surface 421a and the second conical surface 422a are respectively used for secondary shaping of the first slope 202 and the second slope 203. Since the outer diameters of the first slope pressing wheel 421 and the second slope pressing wheel 422 are larger than the outer diameter of the ridge top groove pressing wheel 423, the depth of the groove 201 is deeper than that of the groove 204. Thus, the quality of the trough-shaped ridge can be further improved.

[0050] Optionally, along the axial direction of the mounting shaft 41, the maximum width of the first slope pressing wheel 421 and the maximum width of the second slope pressing wheel 422 are smaller than the maximum width of the ridge top groove pressing wheel 423. The maximum width of the first slope pressing wheel 421 is the distance between the centers of both ends of the first slope pressing wheel 421 along the axial direction of the mounting shaft 41. The maximum width of the second slope pressing wheel 422 is the distance between the centers of both ends of the second slope pressing wheel 422 along the axial direction of the mounting shaft 41. The maximum width of the ridge top groove pressing wheel 423 is the distance between the centers of both ends of the ridge top groove pressing wheel 423 along the axial direction of the mounting shaft 41.

[0051] Thus, the forming quality of the grooved ridge 200 can be further improved.

[0052] In some embodiments, along the axial direction of the mounting shaft 41, the distance between the first ridge slope pressing wheel 421 and the ridge top pressing groove wheel 423 is adjustable to change the size of the first ridge top flattening portion 424; and / or, along the axial direction of the mounting shaft 41, the distance between the second ridge slope pressing wheel 422 and the ridge top pressing groove wheel 423 is adjustable to change the size of the second ridge top flattening portion 425.

[0053] The distance between the first ridge slope pressing wheel 421 and the ridge top pressing groove wheel 423 can be adjusted by adjusting the position of the first ridge slope pressing wheel 421 on the mounting shaft 41.

[0054] The distance between the second ridge slope pressing wheel 422 and the ridge top pressing groove wheel 423 can be adjusted by adjusting the position of the second ridge slope pressing wheel 422 on the mounting shaft 41.

[0055] The distance between the first ridge slope pressing wheel 421 and the ridge top pressing groove wheel 423 and the distance between the second ridge slope pressing wheel 422 and the ridge top pressing groove wheel 423 can also be adjusted by adjusting the position of the ridge top pressing groove wheel 423 on the mounting shaft 41.

[0056] As an example, the mounting shaft 41 can be provided with a mounting groove extending along its axial direction. The first ridge slope pressing wheel 421, the second ridge slope pressing wheel 422, and the ridge top pressing groove wheel 423 can be mounted on the mounting shaft 41 by cooperating with the mounting groove through locking pins. When it is necessary to adjust the positions of the first ridge slope pressing wheel 421, the second ridge slope pressing wheel 422, and the ridge top pressing groove wheel 423 on the mounting shaft 41, loosen the locking pins, adjust the positions, and then install the locking pins.

[0057] By making the distance between the first ridge slope pressing wheel 421 and the ridge top pressing groove wheel 423 adjustable and the distance between the second ridge slope pressing wheel 422 and the ridge top pressing groove wheel 423 adjustable, different grooved ridge size requirements can be met, and the versatility can be improved.

[0058] In some embodiments, the height of the secondary shaping assembly 40 is adjustable.

[0059] Thus, it is convenient to adapt to different soil conditions.

[0060] In some embodiments, the ridging device 100 further includes a fixed frame 50, a mounting frame 60 and a telescopic rod 70. The mounting frame 60 is rotatably arranged on the fixed frame 50, and the mounting shaft 41 is arranged on the mounting frame 60; the telescopic end of the telescopic rod 70 is rotatably connected to the mounting frame 60, and the end of the telescopic rod 70 away from the telescopic end is rotatably connected to the fixed frame 50; wherein, the telescopic end of the telescopic rod 70 is extended and retracted to drive the mounting frame 60 to rotate relative to the fixed frame 50, so as to adjust the height of the secondary shaping component 40. A plurality of telescopic rods 70 may be provided.

[0061] Of course, the height adjustment of the secondary shaping component 40 can also be driven by other driving devices, such as telescopic cylinders, telescopic hydraulic cylinders, motors and transmission components.

[0062] In some embodiments, the shaping plate 30 includes a plate body 31 and a gathering portion 32, the plate body 31 is connected to the shell 10, and the gathering portion 32 is connected to the plate body 31; wherein the gathering portions 32 of two opposite shaping plates 30 are bent close to each other along the axial direction of the mounting axis 41.

[0063] The gathering portion 32 has a certain inclination angle with the traveling direction and is in an inward-gathering shape, so that it can quickly gather soil during operation and pile up soil blocks quickly.

[0064] Each gathering part includes a bottom surface and a side surface, and the side surface is adjacent to and connected to the bottom surface. The bottom surface and the side surface are used to squeeze and flatten the slope of the ridge body, and the bottom surface is used to clean the dirt from the ridge ditch.

[0065] In some embodiments, the housing 10 includes two side baffles 11 and a top baffle 12 connected between the two side baffles 11 , and the two side baffles 11 and the top baffle 12 together constitute a receiving groove for receiving the rotary blade 20 .

[0066] The two side baffles 11 and the top baffle 12 may be disposed on the fixing frame 50 .

[0067] The two side baffles 11 and the top baffle 12 together form a receiving groove for accommodating the rotary tiller 20, so that the crushed soil thrown out by the rotary tiller 20 can collide with the shell 10 more, making the secondary soil crushing more complete, the soil blocks more finely broken, and further increasing the fluidity of the soil blocks.

[0068] An embodiment of the present application also provides a ridging method, which is applied to the ridging device 100 mentioned above, wherein the ridging device 100 performs the following operations during the moving process.

[0069] The soil is cut by the rotary tiller 20 to complete the primary soil crushing, and the primary soil crushing is thrown to the inner wall of the housing 10 to complete the secondary soil crushing;

[0070] The shell 10 and the shaping plate 30 are used together to pile up the secondary crushed soil to form a ridge body having a first slope surface 202 and a second slope surface 203;

[0071] The top of the ridge body is compacted by the ridge top grooving wheel 423, the first ridge top flattening part 424 and the second ridge top flattening part 425, so that grooves 204 are formed on the top of the ridge body and two top surfaces (the first top surface 205 and the second top surface 206) are respectively located on both sides of the groove 204. And the first slope surface of the ridge 202 and the second slope surface of the ridge 203 are respectively extruded by the first ridge slope pressing wheel 421 and the second ridge slope pressing wheel 422 to complete the secondary shaping of the first slope surface 202 and the second slope surface 203.

[0072] The rotary tillage blade 20 cuts the soil and throws the primary soil crushing to the inner wall of the housing 10 to achieve secondary soil crushing. Through the secondary soil crushing, the soil blocks are finer, increasing the fluidity of the soil blocks, which is convenient for the shaping plates 30 and the housing 10 to gather and pile up the soil blocks into a ridge body. At the same time, the two shaping plates 30 respectively extrude the two slope surfaces of the ridge body (the first slope surface 202 and the second slope surface 203), forming the primary shaping of the slope surface of the ridge body, so that the proportion of fine soil on the surface layer of the slope surface of the ridge body is large, that is, the relative proportion of fine soil blocks on the surface layer of the ridge body and large soil blocks in the middle layer is large. And the shaping plates 30 can also scrape the soil blocks in the ridge trench, thus leveling the ridge trench. The top of the ridge body is compacted by the ridge top grooving wheel 423, the first ridge top flattening part 424 and the second ridge top flattening part 425, so that grooves 204 are formed on the top of the ridge body and two top surfaces (the first top surface 205 and the second top surface 206) are respectively located on both sides of the groove 204. And, the first slope surface of the ridge 202 and the second slope surface of the ridge 203 are respectively extruded by the first ridge slope pressing wheel 421 and the second ridge slope pressing wheel 422 to complete the secondary shaping of the first slope surface 202 and the second slope surface 203, making the first slope surface 202, the second slope surface 203, the groove 204, the first top surface 205 and the second top surface 206 of the formed trough-shaped ridge have higher flatness and better linearity, which is convenient for the subsequent efficient operation of the pond digging and transplanting integrated machine.

[0073] Refer to Figure 6 , the formation of the trough-shaped ridge generally goes through three stages. The first stage is soil loosening and crushing, the soil is crushed once by the blades on the rotary tillage blade 20, and the soil is crushed twice by the housing 10. The first stage is the primary shaping of the ridge body. The crushed soil is pushed up to form a ridge body by the shaping plates 30 and the housing 10, and the shaping plates 30 extrude the slope surface once to clean the trench. The third stage is the secondary shaping of the ridge body. The first slope surface 202 and the second slope surface 203 are respectively extruded twice by the first ridge slope pressing wheel 421 and the second ridge slope pressing wheel 422. The top of the ridge body is compacted by the ridge top grooving wheel 423, the first ridge top flattening part 424 and the second ridge top flattening part 425, so that grooves 204 are formed on the top of the ridge body and two top surfaces (the first top surface 205 and the second top surface 206) are respectively located on both sides of the groove 204.

[0074] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
