Description

Technical Field

[0001] The present invention relates to the technical field of soil scarifying equipment, in particular to an agricultural soil scarifier. Background Art

[0002] In agricultural production, soil looseness is crucial to crop growth. Loose soil promotes the growth and development of crop roots, better retains water and nutrients, and improves soil aeration, thereby promoting healthy crop growth. Traditional soil loosening methods rely primarily on manual labor using tools such as hoes and plows. This method is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale agricultural production.

[0003] With the development of agricultural mechanization, various agricultural tillers have emerged. Existing agricultural tillers usually include a power unit, a transmission device and a loosening component, wherein the loosening component usually uses a rotary blade assembly to loosen the soil.

[0004] However, in practice, traditional rotary tillers lack weed-cutting and anti-entanglement structures. When encountering long, dense weeds, the rotation of the blade can trap the weeds between the blade and the blade shaft. As the blade continues to rotate, the weeds become increasingly entangled. Especially in humid conditions, weeds cling to each other, accelerating the entanglement process. The entangled weeds increase the resistance to the blade's rotation, leading to increased power loss and, in severe cases, even preventing the blade from rotating properly. This significantly reduces the efficiency of the tillage operation and increases the farmer's cleaning burden and time costs. Summary of the Invention

[0005] The main purpose of the present invention is to provide an agricultural tiller, which solves the problem that traditional rotary tillers are easily entangled in weeds, resulting in large power loss and low operating efficiency, by arranging main cutter bodies and auxiliary cutter bodies at intervals and staggered distribution on the rotating shaft, thereby improving the efficiency and quality of tilling operations, reducing the burden on farmers, and meeting the diversified agricultural production needs.

[0008] In a possible implementation, the elastic reset structure includes a fixed disk fixedly disposed on the rotating shaft. The fixed disk and the mounting disk are coaxially disposed with the rotating shaft, and a coil spring is connected therebetween.

[0009] In a possible embodiment, the cutting edge on one side of the auxiliary blade body includes a plurality of guide portions equidistantly arranged on one side of the auxiliary blade body, and a cutting gap with a larger opening on the outside and a smaller opening on the inside is formed between adjacent guide portions, and the peripheral sides of the cutting gap are all arranged in a blade shape.

[0010] In a possible implementation manner, the thickness of the guide portion gradually becomes thinner from the end away from the auxiliary tool body toward the auxiliary tool body, and the end of the guide portion is configured as an arc head.

[0011] In a possible implementation manner, a pair of drive disks are fixedly provided on the rotating shaft, and the plurality of main blade bodies are circumferentially arranged between the pair of drive disks.

The angle adjustment component is used to adjust the insertion angle of a plurality of soil turning heads when they are inserted into the soil.

[0014] In one possible embodiment, the angle adjustment assembly includes a support plate arranged on the drive disk, an adjustment motor electrically connected to the control module is provided on the support plate, and the adjustment motor is provided with one, which is connected to one of the operating shafts; and also includes a transmission assembly connected to several operating shafts, and the transmission assembly is used to make the several operating shafts rotate synchronously in the same direction.

[0021] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] like Figure 1-8 As shown, the present invention provides an agricultural tiller, comprising a vehicle body 1 with a driving unit 2 and a tiller component 3 provided on the vehicle body 1, wherein the driving unit 2 is used to drive the vehicle body 1 and the tiller component 3 to work, as shown in FIG. Figure 1-3 As shown, it includes a power source and a control module arranged on the vehicle body 1. The control module is arranged at the handle position of the vehicle body 1 to facilitate the user to perform control operations. The power source is a drive motor 5 fixed on the vehicle body 1. The output shaft of the drive motor 5 is connected to a sub-power box 6 through a coupling. The sub-power box 6 is respectively connected to the motion mechanism of the vehicle body 1 and the loosening component 3.

[0024] like Figure 3 As shown, the movement mechanism of the vehicle body 1 is a sprocket connected to the wheel, and the sprocket is connected to one of the output shafts of the power distribution box 6 through a sprocket set 7 and a chain, thereby realizing power transmission, so that the vehicle body 1 can automatically move forward under the action of the drive motor 5, thereby allowing users to save more effort and improve efficiency during work.

[0025] The loosening component 3 includes a rotary tillage bracket 30 connected to the vehicle body 1, and a rotating shaft 31 connected to the driving unit 2 is rotatably provided on the rotary tillage bracket 30. Specifically, Figure 2As shown, a transmission wheel 8 is provided on the rotating shaft 31, and a driving wheel 9 is provided on the output shaft at the other end of the sub-power box 6, which is connected to the transmission wheel 8 on the rotating shaft 31. The driving wheel 9 and the transmission wheel 8 are driven by a transmission chain or belt, thereby driving the rotating shaft 31, and then driving the main blade body 32 and the auxiliary blade body 33 to rotate, thereby completing the loosening of the soil.

[0026] Among them, such as Figure 4-5 As shown, a plurality of main blade bodies 32 and auxiliary blade bodies 33 are arranged on the rotating shaft 31 in a circumferential distribution with the rotating shaft 31 as the center. The main blade bodies 32 and the auxiliary blade bodies 33 are arranged alternately at intervals, and the auxiliary blade bodies 33 are located on the side of the main blade body 32 close to the rotating shaft 31; the auxiliary blade body 33 is long and has a comb-shaped cutting blade 37 along one side thereof along the rotation direction relative to the rotating shaft 31. The cutting blade 37 is used to cut weeds during the rotation of the auxiliary blade body 33.

[0027] When the tiller starts working, the drive unit 2 drives the rotating shaft 31 to rotate at high speed, and the main blade body 32 and the auxiliary blade body 33 installed on the rotating shaft 31 perform circular motion accordingly. Since the auxiliary blade body 33 is located on the side of the main blade body 32 close to the rotating shaft 31 and is staggered at intervals, during the rotation process, the auxiliary blade body 33 will be the first to contact the weeds due to its position advantage. The auxiliary blade body 33 is long and has a comb-like cutting edge 37 on one side of the rotation direction relative to the rotating shaft 31, which penetrates into the weeds like a comb. Under high-speed rotation, the comb-like cutting edge 37 uses its sharp cutting edge to cut the weeds. Since the comb teeth are reasonably spaced, the weeds will not accumulate excessively between the comb teeth, ensuring smooth cutting.

[0028] Under the influence of centrifugal force, the cut weeds fly away from the secondary blade body 33 along the tangential direction, making it difficult for them to get close to the space between the primary blade body 32 and the blade shaft. This effectively prevents weeds from becoming entangled between the primary blade body 32 and the blade shaft, thereby reducing the additional resistance during the rotation of the cutter head and reducing power loss. This eliminates the need for the drive unit 2 to consume excessive energy to overcome the resistance caused by entangled weeds, thereby improving energy utilization efficiency.

[0029] After the auxiliary blade 33 completes the weed-cutting pre-processing, the main blade 32 smoothly cuts into the soil to loosen it. Without the interference of weeds, the main blade 32 can rotate more stably, maintaining efficient loosening. This collaborative operation between the main blade 32 and the auxiliary blade 33 not only improves loosening efficiency but also ensures the continuity of the loosening operation, reducing the frequency of machine failures or downtime due to weeds, significantly improving the overall operational efficiency of the scarifier.

[0030] Among them, Figure 4-7As shown, the specific structure of the auxiliary blade body 33 is that a pair of mounting plates 34 are rotatably connected to the rotating shaft 31, and a plurality of connecting rods 35 extending away from the rotating shaft 31 are circumferentially arranged on the mounting plates 34, and the auxiliary blade body 33 is fixedly arranged between the pair of connecting rods 35; it also includes an elastic reset structure 36 arranged between the mounting plates 34 and the rotating shaft 31, and the elastic reset structure 36 is used to drive the auxiliary blade body 33 to reset and rotate in the rotation direction of the rotating shaft 31; wherein the elastic reset structure 36 includes a fixed plate 360 ​​fixedly arranged on the rotating shaft 31, and the fixed plate 360 ​​and the mounting plate 34 are coaxially arranged with the rotating shaft 31, and a coil spring 361 is connected between the two.

[0031] When the agricultural tiller is in operation, the shaft 31 begins to rotate, driven by the drive unit 2. A pair of mounting plates 34 attached to the shaft 31 rotate accordingly. Because the auxiliary blade body 33 is secured between connecting rods 35 extending circumferentially from the mounting plates 34, the auxiliary blade body 33 also moves in a circular motion around the shaft 31. During this motion, the comb-like cutting edges 37 on the auxiliary blade body 33 cut the weeds.

[0032] When the auxiliary blade body 33 encounters greater resistance, such as when cutting tough weed roots or encountering hard objects hidden in the weeds, the auxiliary blade body 33 will be subjected to a force opposite to the rotation direction of the rotating shaft 31. At this time, the elastic reset structure 36 between the mounting plate 34 and the rotating shaft 31 comes into play. The coil spring 361 in the elastic reset structure 36 is connected to the fixed plate 360 ​​fixed on the rotating shaft 31 at one end, and to the mounting plate 34 at the other end. Under the action of resistance, the coil spring 361 undergoes elastic deformation, storing elastic potential energy, allowing the mounting plate 34 to drive the auxiliary blade body 33 to rotate in the opposite direction relative to the rotating shaft 31 at a certain angle, so as to cushion the impact of the resistance on the auxiliary blade body 33 and the entire structure, and prevent the auxiliary blade body 33 from being damaged due to rigid force.

[0033] When the resistance disappears, the coil spring 361 releases its stored elastic potential energy, driving the mounting plate 34 to drive the auxiliary blade body 33 to return to the rotation direction of the rotating shaft 31, so that the auxiliary blade body 33 can continue to maintain a normal cutting position and angle and continue to cut the weeds.

[0034] This structural design effectively solves the problem of the auxiliary blade body 33 being easily damaged by unexpected resistance during weed cutting. Furthermore, the elastic reset structure 36 enables the auxiliary blade body 33 to adaptively adjust its position and angle in complex weed environments, enhancing cutting stability and continuity, ensuring efficient weed cutting, and ultimately improving the overall operating efficiency of the scarifier while reducing repair costs and operational downtime caused by damage to the auxiliary blade body 33.

[0035] Further, such as Figure 7As shown, the cutting edge 37 on one side of the auxiliary blade body 33 includes a plurality of guide portions 370 equidistantly arranged on one side of the auxiliary blade body 33, and a cutting gap 371 with an opening that is larger on the outside and smaller on the inside is formed between adjacent guide portions 370, and the circumference of the cutting gap 371 is arranged in a blade shape; and the thickness of the guide portion 370 gradually becomes thinner from the end away from the auxiliary blade body 33 toward the auxiliary blade body 33, and the end of the guide portion 370 is arranged as an arc head 372.

[0036] Specifically, the cutting edge 37 is composed of a plurality of guide portions 370 equidistantly arranged on one side of the auxiliary blade body 33 . These guide portions 370 have the key function of guiding weeds into the cutting area during rotation.

[0037] The thickness of the guide portion 370 gradually tapers from the end away from the secondary blade body 33 toward the secondary blade body 33, and the end is designed with a rounded head 372. This ingenious design has multiple benefits: when contacting weeds, the rounded head 372's smooth shape allows it to smoothly push away weeds, effectively reducing direct impact and preventing them from being scattered due to excessive force. Furthermore, the gradually tapering design makes it easier for the guide portion 370 to be inserted into weeds.

[0038] Furthermore, the rounded end 372 provides crucial protection when encountering hard objects such as rocks during weeding. Compared to a sharp end, the rounded end 372 applies force over a larger area when colliding with hard objects, dispersing the impact force and reducing the risk of damage to the auxiliary blade 33 due to excessive localized force.

[0039] Adjacent guide portions 370 form cutting gaps 371, which are larger on the outside and smaller on the inside. Once weeds are successfully guided into the cutting gaps 371, their unique shape, larger on the outside and smaller on the inside, gradually gathers the weeds within them. The edges of the cutting gaps 371 are blade-like. As the auxiliary blade body 33 rotates, the blade-like edges exert a shear force on the weeds gathered within the gaps, thereby severing them.

[0040] This structural design of the cutting blade 37 effectively solves a series of problems, including uneven weed cutting, splashing, and low cutting efficiency. The unique shape of the guide 370 and the carefully designed cutting gap 371 not only significantly improve the success rate of weed cutting, but also ensure a smoother cutting process, greatly reducing the possibility of weeds entangled on the cutting blade 37, and extending the service life of the auxiliary blade body 33.

[0041] On the basis of the above, a pair of driving disks 38 are fixedly provided on the rotating shaft 31 , and a plurality of main blade bodies 32 are circumferentially arranged between the pair of driving disks 38 .

[0042] Specifically, such as Figure 6As shown, a pair of drive discs 38 are provided with a plurality of circumferentially arranged connecting holes; the main blade body 32 includes an operating shaft 320 arranged between the pair of drive discs 38 through the connecting hole, and the operating shaft 320 is fixed with a plurality of scimitar-shaped turning heads 321, which are arranged at equal distances along the axial direction of the operating shaft 320, and the turning heads 321 are bent and extended in the rotation direction of the rotating shaft 31; and the operating shaft 320 is rotatably arranged between the pair of drive discs 38, and an angle adjustment component 4 is also provided between the drive disc 38 and the operating shaft 320, and the angle adjustment component 4 Used to adjust the insertion angle of several turning heads 321 when they are inserted into the soil; the angle adjustment component 4 includes a support plate 40 arranged on the drive disk 38, and an adjustment motor 41 electrically connected to the control module is provided on the support plate 40, and the adjustment motor 41 is provided with one, which is connected to one of the operating shafts 320; it also includes a transmission component connecting several operating shafts 320, the transmission component includes a driving gear 42 arranged at the end of several operating shafts 320, and the several driving gears 42 are connected to each other by rotating the transmission gear 43 arranged on the drive disk 38.

[0043] When the tiller starts working, the driving disc 38 rotates under the power, which in turn drives the operating shaft 320 and the tiller head 321 to rotate. The tiller head 321 cuts into the soil with its scimitar shape, turning and breaking the soil to achieve the soil loosening function. However, different soil conditions and crop planting requirements have different requirements for the loosening depth and angle, which requires the tiller head 321 to be inserted into the soil at an adjustable angle.

[0044] At this time, the angle adjustment assembly 4 comes into play. The support plate 40 in the angle adjustment assembly 4 is fixed on the drive disk 38. An adjustment motor 41 electrically connected to the control module is installed on the support plate 40, and only one adjustment motor 41 is connected to one of the operating shafts 320. The transmission assembly connecting the multiple operating shafts 320 is composed of a driving gear 42 set at the end of each operating shaft 320 and a transmission gear 43 that rotates on the drive disk 38. When the control module issues an instruction, the adjustment motor 41 starts, driving the operating shaft 320 connected to it to rotate, and the driving gear 42 at the end of the operating shaft 320 rotates accordingly. The transmission gear 43 engages with the driving gears 42 at the ends of other operating shafts 320, realizing the synchronous and unidirectional rotation of the multiple operating shafts 320, thereby adjusting the insertion angle of all the turning heads 321 when they are inserted into the soil.

[0045] This design effectively solves the problem of the traditional tiller's main blade 32 having a fixed turning angle, making it difficult to adapt to different soil and crop needs. The adjustable insertion angle of the tiller head 321 allows the tiller head 321 to be inserted deeper into the soil when working with harder soils, such as clay, allowing it to break up the soil with greater torque, improving the loosening effect. When working with looser soils, such as sandy soil, or for shallow-rooted crops, the insertion angle can be reduced to avoid damage to the soil structure and crop roots caused by excessive loosening. This not only improves the adaptability of the tiller in different operating scenarios, but also optimizes the loosening quality, meeting the diverse needs of agricultural production and improving operational efficiency and the quality of the crop growth environment.

[0046] Furthermore, in the technology of the above-mentioned scheme, a sliding connection can be adopted between the rotating shaft 31 and the rotary tillage bracket 30, so that the height of the rotating shaft 31 can be adjusted up and down, thereby adjusting the depth of loosening the soil. Specifically, a support block 10 is slidingly arranged on the rotary tillage bracket 30, and the rotating shaft 31 is rotatably arranged on the support block 10, and a screw 11 is arranged between the support block 10 and the rotary tillage bracket 30, and one end of the screw 11 is connected to the rotating motor 12. The height of the support block 10 can be adjusted by rotating the rotating motor 12 to drive the height adjustment of the rotating shaft 31.
