Description

Technical Field

[0001] The present invention relates to the field of crop planting, in particular to a soil-raising machine and a soil-raising method. Background Art

[0002] In the field of agricultural cash crop cultivation, such as tobacco, when the crop seedlings reach a certain stage of growth, it is generally necessary to add soil to the crop ridges. That is, while weeding the sides of the ridges where the crops are growing, soil from the bottom and sides of the ridges is piled onto the crop roots at the top of the ridges. This improves the growth environment of the crop roots and increases their depth, thereby improving yield, quality, and lodging resistance. Traditionally, adding soil is generally done manually with handheld tools. Currently, in cases where soil conditions are good (sandy loam) and the requirements for adding soil are not high, some people use soil-adding machines for adding soil. However, in some areas, such as southern Hunan, due to the extremely high toughness and viscosity of the soil, if soil is to be accurately added to the top of the crop root pocket, extremely high requirements are placed on the soil-adding ability of the soil-adding machine. So far, manual soil-adding has basically been used to solve the above problems.

[0003] Existing soil-raising machines are generally equipped with one or two driving wheels with a diameter of less than 40 cm for passing within a single ridge. The soil-raising plows are horizontally distributed on a plow shaft. When the plows are performing soil-raising operations, the rotating surface of the plow is always perpendicular to the horizontal plane. After the soil is dug up, the soil is turned over by the soil-raising blades and the inclined surface of the rear side of the plow is used to throw it onto the ridge surface on one side or both sides. When the soil is clay soil with a large amount of water, especially when there is water accumulation and the bottom of the ditch is in a muddy state, the soil is affected by the viscosity of the soil. Due to the strong adhesion of the soil to the blades, the lateral throwing effect is obviously insufficient, so that the roots of the crops that need soiling the most are not covered with soil at all. Therefore, the current soil-raising machines cannot meet the soiling needs of crops in areas with particularly high toughness and viscosity of the soil. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a soil-raising machine and a soil-raising method, which can make up for the defect that the existing soil-raising machine has a poor soil-raising effect in soil with excessive viscosity.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A soil-raising machine comprises a driving device, a soil-raising device and a guide device connected in sequence along a first direction;

[0007] The soil-raising device includes a transmission mechanism, a transmission box, a plowshare soil-throwing mechanism and a soil-retaining mechanism;

[0008] The driving device is in transmission connection with the transmission mechanism;

[0009] The two ends of the transmission mechanism are respectively connected to the corresponding plow blade throwing mechanism through a transmission box;

[0010] The axis of the transmission mechanism is parallel to the second direction, and the first direction and the second direction are perpendicular to each other;

[0011] A first angle greater than 100° and less than 120° is formed between the longitudinal direction of the transmission case and the axis of the transmission mechanism, and a second angle greater than or equal to 90° is formed between the axis of the plow blade throwing mechanism and the longitudinal direction of the transmission case;

[0012] The soil retaining mechanism is connected to the transmission box, and has a retraction channel distributed along the first direction. The soil retaining mechanism also has a blocking member, and at least a portion of the blocking member is arranged opposite to the soil throwing port of the plow blade soil throwing mechanism.

[0013] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0014] A soil training method comprises the following steps:

[0015] The crops are gathered into the gathering channel inside the soil retaining mechanism through the soil retaining mechanism; the two plow blade soil throwing mechanisms cut into the ridge body from both sides respectively and throw soil in the direction gradually approaching the ridge top, and the rotation axis of the plow blade soil throwing mechanism forms an angle of 10° to 30° with the horizontal plane formed by the first direction and the second direction.

[0016] The beneficial effects of the present invention are as follows: by providing a plowshare throwing mechanism and making the rotation axis of the plowshare throwing mechanism have an angle of 10° to 30° with the horizontal plane formed by the first and second directions, the present invention can adapt to the shape of the ridge side, allowing the rotating surface of the plowshare throwing mechanism to deeply excavate and weed the soil surface and ridge base of the ridge, while also allowing the excavated broken soil and grass to be thrown onto the crop root pocket at the top of the ridge along a parabolic motion trajectory. Compared with existing soil-raising machines, the performance and effects of soil extraction, weeding, and throwing are improved and enhanced, and can meet the soil-raising requirements of soil conditions with high moisture content and high viscosity. A soil retaining mechanism is provided to cushion and guide the thrown clay, so that the soil can be thrown to the appropriate position at the top of the ridge. The present invention adopts an inclined plow blade throwing mechanism to overcome the defects of existing soil-throwing machines that have poor throwing effect and unreliable performance for soil with high viscosity, so that the soil can be thrown to the specified position at a suitable angle after being dug up. Without increasing the driving force, the digging depth and the throwing force can be improved, which is more suitable for soil with high viscosity. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0034] Please refer to Figure 1-Figure 5, a soil-raising machine comprises a driving device 1, a soil-raising device 2 and a guide device 3 connected in sequence along a first direction; the soil-raising device 2 comprises a transmission mechanism 21, a transmission box 22, a plow blade throwing mechanism 23 and a soil retaining mechanism 24; the driving device 1 is transmission-connected to the transmission mechanism 21; both ends of the transmission mechanism 21 are transmission-connected to the corresponding plow blade throwing mechanism 23 through a transmission box 22; the axis of the transmission mechanism 21 is parallel to the second direction, and the first direction and the second direction are perpendicular to each other; a first angle α is formed between the length direction of the transmission box 22 and the axis of the transmission mechanism 21, which is greater than 90° and less than 120°, and a second angle β is formed between the axis of the plow blade throwing mechanism 23 and the length direction of the transmission box 22; the soil retaining mechanism 24 is connected to the transmission box 22, and a retraction channel 240 distributed along the first direction is provided in the soil retaining mechanism 24, and the soil retaining mechanism 24 has a blocking member 241, and the blocking member 241 is at least partially arranged opposite to the soil throwing port of the plow blade throwing mechanism 23. Among them, the guide device 3 includes two relatively arranged guide assemblies 31, the guide assembly 31 includes a guide wheel 311 and a guide frame 312, one end of the guide frame 312 is connected to the transmission box 22, and the other end of the guide frame 312 has a wheel fork 313. The length direction of the wheel fork 313 is inclined relative to the radial direction of the guide wheel 311, and the end of the wheel fork 313 connected to the guide wheel 311 to the end of the wheel fork 313 connected to the guide frame 312 is inclined in a direction gradually away from the drive device 1, that is, with reference to Figure 1 The longitudinal direction of the wheel fork 313 and the vertical direction form a third angle θ that is less than 45°. The guide assembly 31 can automatically correct the deviation, so that the plow blade throwing mechanism 23 always moves in the first direction. Preferably, the third angle θ is 34°.

[0035] It is understood that the present invention, by providing a plowshare throwing mechanism 23 and forming an angle between the axis of the plowshare throwing mechanism 23 and the axis of the transmission mechanism 21 to adapt to the shape of the ridge surface, digs the soil more deeply. After being dug up, the soil can move parabolically and be thrown to the top of the ridge. Compared with existing soil-raising machines, both digging and throwing effects are better, and it is suitable for soils with higher viscosity. A retaining mechanism 24 is provided to cushion and guide the thrown clay, so that the soil is thrown to the appropriate position on the top of the ridge. The present invention uses an inclined plowshare throwing mechanism 23 to overcome the shortcomings of existing soil-raising machines that have poor throwing effects on soils with higher viscosity. After being dug, the soil is thrown to the designated position at an appropriate angle. Without increasing the driving force, the digging depth and throwing force are increased, making it more suitable for soils with higher viscosity. Among them, the guide device 3 is used to cooperate with the driving device 1 to form a stable drive structure, while also supporting and guiding the plowshare throwing mechanism 23. Specifically, the drive device 1 includes a drive assembly 11, a drive frame 12, and a drive wheel 13. The two ends of the drive frame 12 are respectively connected to the two drive wheels 13. The drive assembly 11 is respectively connected to the drive frame 12 and the plow blade throwing mechanism 23. The drive frame 12 is connected to the transmission mechanism 21 via a crossbeam 14.

[0036] In some embodiments, the soil-cultivating device 2 further includes a cover 25; the cover 25 is connected to the transmission case 22 and surrounds the plow blade throwing mechanism 23. The cover 25 has an opening 251 on the side facing away from the transmission case 22, and a clearance opening 252 is formed on the side facing away from the transmission mechanism 21, allowing the plow blade throwing mechanism 23 to contact the soil. Specifically, the cover 25 is configured to guide and block excavated soil, preventing it from being thrown into other areas and ensuring effective soil throwing.

[0037] In some embodiments, the soil retaining mechanism 24 includes two opposing soil retaining frames 242, two opposing leaf lifting frames 243, and two opposing blocking members 241. A collection channel 240 is formed between the two soil retaining frames 242 and the two leaf lifting frames 243. The leaf lifting frames 243 are connected to one end of the soil retaining frames 242 near the guide device 3. A portion of the blocking member 241 is connected to the soil retaining frames 242, while another portion of the blocking member 241 is connected to a side edge of the cover 25 near the guide device 3. The two soil retaining frames 242 and the two leaf lifting frames 243 are provided to form the collection channel 240 to protect crops during the soil cultivation process. The blocking members 241 are provided to guide and cushion the thrown soil, causing it to strike the blocking members 241 and fall to the top of the ridge. Specifically, the soil retaining frames 242 extend away from the transmission case 22, providing ample space for the thrown soil to move.

[0038] In some embodiments, each leaf lifting rack 243 is connected to a corresponding soil retaining rack 242; the distance between the two leaf lifting racks 243 gradually increases from the side where the driving device 1 is located to the side where the guide device 3 is located, so as to expand the range of collecting crops and provide full protection for the crops.

[0039] In some embodiments, the blocking member 241 is made of a flexible material, which can not only buffer the soil but also guide the soil. Because it is made of a flexible material, when the soil hits the blocking member 241, the blocking member 241 will deform, and the soil will fall along the surface of the blocking member 241 to the top of the ridge.

[0040] In some embodiments, the opening 251 of the cover body 25 is at least partially arranged opposite to the blocking member 241. Specifically, the area of ​​the opening 251 of the cover body 25 close to the transmission mechanism 21 is arranged opposite to a part of the area of ​​the blocking member 241. After the soil is excavated by the plow blade throwing mechanism 23, it will be thrown along the side of the cover body 25 close to the transmission mechanism 21 and collide with the blocking member 241, thereby buffering the soil.

[0041] In some embodiments, the leaf lifting frame 243 gradually sinks from the side where the driving device 1 is located to the side where the guide device 3 is located, and is used to contact the stems of the crops, thereby gathering the crops into the gathering channel 240 to avoid damaging the leaves of the crops. Specifically, the leaf lifting frame 243 is triangular in shape, and has a first leaf lifting edge 2431, a second leaf lifting edge 2432, and a third leaf lifting edge 2433 arranged in sequence. The first leaf lifting edge 2431 and the third leaf lifting edge 2433 gradually sink from the side where the driving device 1 is located to the side where the guide device 3 is located, wherein the angle formed between the first leaf lifting edge 2431 and the longitudinal direction of the soil retaining frame 242 is greater than the angle formed between the second leaf lifting edge 2432 and the longitudinal direction of the soil retaining frame 242.

[0042] In some embodiments, the plow blade throwing mechanism 23 includes a rotating shaft 231 and a throwing blade 232 ; the throwing blade 232 is connected to the transmission box 22 via the rotating shaft 231 . Specifically, the transmission box 22 is connected to the transmission mechanism 21 via a cross coupling 26 .

[0043] A soil cultivation method includes the following steps: crops are gathered into a gathering channel 240 in the soil retaining mechanism 24 by a soil retaining mechanism 24; two plowshare soil throwing mechanisms 23 are respectively inserted from both sides of the ridge body to the ridge base and throw soil in a direction gradually approaching the ridge top, and the rotation axis of the plowshare soil throwing mechanism forms an angle of 10 to 30 degrees with the horizontal plane formed by the first direction and the second direction.

Specifically, the transmission mechanism 21 includes a housing 211, a clutch 212, and a drive shaft 213. The drive shaft 213 is rotatably mounted within the housing 211. The clutch 212 is in transmission connection with the drive shaft 213. The clutch 212 is in chain transmission connection with the drive device 1. Both ends of the drive shaft 213 are also in transmission connection with corresponding transmission boxes 22.

[0046] In this embodiment, the soil-raising device 2 also includes a cover 25; the cover 25 is connected to the transmission box 22 and is arranged around the outside of the plow blade throwing mechanism 23; the cover 25 has an opening 251 on the side away from the transmission box 22, and the cover 25 has a clearance opening 252 on the side away from the transmission mechanism 21 for the plow blade throwing mechanism 23 to contact the soil.

[0047] In this embodiment, the soil retaining mechanism 24 includes two opposing soil retaining frames 242, two opposing leaf lifting frames 243, and two opposing blocking members 241. A retraction channel 240 is formed between the two soil retaining frames 242 and the two leaf lifting frames 243. The leaf lifting frames 243 are connected to one end of the soil retaining frames 242 near the guide device 3. A portion of the blocking member 241 is connected to the soil retaining frames 242, and another portion of the blocking member 241 is connected to a side edge of the cover 25 near the guide device 3. Preferably, the blocking member 241 is made of a flexible material, such as nylon cloth.

[0048] In this embodiment, the opening 251 of the cover 25 is disposed adjacent to the transmission mechanism 21 and is located opposite to a portion of the blocking member 241 .

[0049] In this embodiment, the leaf lifting frame 243 gradually sinks from the side where the driving device 1 is located to the side where the guiding device 3 is located.

[0050] In this embodiment, the plow blade throwing mechanism 23 includes a rotating shaft 231 and a throwing blade 232. The throwing blade 232 is connected to the transmission box 22 via the rotating shaft 231. Specifically, the transmission box 22 is connected to the transmission mechanism 21 via a cross coupling 26.

[0051] The working principle of this embodiment is:

In practice, as long as the rotation plane of the plowshare throwing mechanisms 23 forms an angle of 10° to 30° with the horizontal plane formed by the first and second directions, and the rotation plane gradually tilts toward the ridge body 4 from bottom to top, the soil-building effect can be improved and the resistance of the plowshare throwing mechanisms 23 during soil-building can be reduced. The ridge base refers to the base portion of the ridge body.
